Description

The invention relates to a liquid dispensing device, especially a hand-held sprinkler for the Home and garden area according to the preamble of claim 1.

Such mostly hand-held liquid dispensing devices, usually attached to the end of a garden hose have a flowable, single or multi-part, expediently accessible housing, which for Introducing liquid into the housing a liquid inlet assigned, which is usually at the rear end of a Handle area is arranged. Furthermore, the housing a first nozzle device and one separate from this second nozzle device for dispensing liquid from the Assigned housing. The nozzle devices serve to pass through their shape to determine in what form the dispensed Liquid emerges from the liquid dispenser and are appropriately designed to be different Allow dispensing types. The term nozzle device in this application includes all of the fluid delivery suitable facilities that have a flow shaping Have an effect on the dispensed liquid. In the simplest Case can be an opening of a given form. Furthermore, it is expedient to operate a liquid control device which can be operated manually to control the liquid flow between the liquid inlet and the nozzle devices intended.

There are many such liquid dispensers Executions. Facilities have already been proposed been where one or two different Nozzle-bearing nozzle holder against one with the liquid inlet connected output is rotatable, depending on the position of the nozzle carrier each with one of the nozzle devices to connect the liquid inlet. The necessary for this Movement of the nozzle devices can be limited affect the type and size of the nozzles. In addition, there are Facilities relatively complex.

DE 29 40 899 shows another type as a spray head trained, generic liquid delivery device. It has one with a rear hose connection Pipe socket, one on an external thread of the pipe socket screw-on nozzle body, one on an external thread of the Nozzle body screwable inner sleeve and one on one External thread of the inner sleeve screw-on jacket sleeve. The pipe socket and the nozzle body are closed trained top and have just like the inner one Sleeve, side outlet openings from which inflowing Water in the between the sleeve and the nearest outside Sleeve formed space can flow. At the front end the device has two different versions, concentric nozzle devices are provided, with a central front nozzle opening of the inner sleeve, into which a tip of the nozzle body protrudes, from one annular shower nozzle device with annular perforated plate is surrounded. Form the sleeves screwed into each other Control elements of a liquid control device that it by mutually twisting the sleeves and thus by mutual axial displacement of the sleeves allows only that centric spray nozzle or the outer shower ring with of flowing liquid. Also intermediate positions, where both the spray nozzle and the shower with variable, adjustable by turning the sleeves Quantities of water can be applied. The spray head allows many different delivery options for the Liquid, however, is both in the making, as well complicated to use. Another establishment of this Kind, which is also a variety of coaxial, one inside the other screwable sleeves for fluid control, and also with a central spray nozzle of one coaxial, annular shower device is surrounded, is in EP 0 842 705. Even with this facility, which in is able to water with a variety of different Providing irrigation patterns is the structure and handling complicated.

The invention has for its object a liquid dispenser of the type mentioned at the outset to create the simple and inexpensive to manufacture and very simple and can be operated reliably.

This object is achieved by a liquid dispenser with the features of claim 1. Preferred further developments are specified in the subclaims. The wording All claims become the content of the by reference Description made.

According to the invention, a directional control valve is included as a control device a rotatable control element provided in the manner of a chick and the control device is designed such that by Rotation of the control gear optionally only the first nozzle device or only the second nozzle device with the liquid inlet connectable or the liquid supply can be shut off is. A control body is referred to here as a chick, that between at least one inlet opening and at least an outlet opening of the control device flow paths defined that can be changed by rotating the chick. It a single tax body is sufficient, through which preferably manual rotation between different operating states the liquid dispenser switched can be. The operating states can change when the Taxes are and are passed one after the other certain, fixed rotational positions of the control member assigned. These positions can e.g. with the help of Alignment of a handle bar of an actuating toggle Control system easily recognizable from the outside and accordingly be securely adjustable. Because in contrast to the described State of the art, with sleeves screwed into each other works, no relative axial displacement of control elements is necessary for adjustment, an inventive Control device to be thread-free, whereby the Manufacture of the control device is particularly simple and inexpensive becomes. The elements of the control device can structurally and functionally completely independent of them of the nozzle devices, which is suitable for both Nozzle devices, as well as for the control device constructive scope.

For simple designs, it can be enough if optional the first or the second nozzle device full of liquid acted upon or the liquid supply to these is cordoned off. In a preferred further development on the other hand, the control device is designed such that Rotation of the control device the flow rates to the first Nozzle device and / or to the second nozzle device is adjustable, the setting preferably being infinitely variable is possible. So it is by operating a single one Tax control not only the complete blocking or Approval of nozzle facilities possible, but for everyone Nozzle devices also have a sensitive dosage of the in the Nozzle device inflowing amount of water. That means a very simple operation of the liquid dispenser.

A preferred development of the liquid control device uses a new, surprising and very effective Principle of fluid control, not only with generic ones Liquid dispensing devices with advantage is usable, but generally in liquid control devices can also be advantageous for other applications. The underlying principle can e.g. explained as follows become. It is envisaged that the control device Control device housing with one for receiving the control member provided, rotationally symmetrical receiving opening has, which is preferably cylindrical, but for example could also be conical. In this opening opens out transversely to one through the inside of the receiving opening defined area, for example in the radial direction, at least one liquid-conducting channel through which to controlling liquid can flow. At the scope of the tax body is at least one with the one serving as the sealing surface Co-rotating inner side of the receiving opening Seal provided, for example, one in a suitable groove-guided O-ring or a round cord seal may have, which is linear over the entire circumference Sealing engagement with the inside of the receiving opening. By the seal will separate two spaces from each other, which are in the axial direction, i.e. parallel to the axis of symmetry of the Receiving opening or the axis of rotation of the control member on the one or on the other side of the seal. On essential aspect is that the seal is not how in conventional sealing arrangements, in a radial plane of the tax body, but that they have at least one has an inclined peripheral portion that is transverse to one Radial plane of the control member or the receiving opening, that in at least one rotational position of the control member the above Channel of an axially sealed by the seal Space is separated and in at least one other Rotational position of the channel opens into this room. By rotation of the control member are so without the control member axially is moved, peripheral portions of the seal related to a Position of a channel mouth axially shifted. Sloping peripheral sections can the channel mouth area in Pass axial direction.

If the between the seal and inside of the receiving opening formed sealing surface is narrower than a diameter of one Channel mouth, so be extreme at the transition between these Run through intermediate rotary positions, at which the seal runs across the channel mouth, so that the channel in both rooms adjacent to the seal flows.

If now in at least one of the adjacent rooms If another channel opens, this is from the first channel separated according to the rotary position of the control member or it is in liquid-conducting connection with this. Among the The conditions described result in intermediate positions with regard to the flow cross-section, which leads to the stepless Control of the flow cross-section and thus the Flow rates can be used. To achieve the the effect described is useful the length and / or Inclination of the inclined peripheral portion of the size of the Channel mouth adjusted so that one of the seal as a whole Axial area swept by rotation has a width that is at least as large as the axial width of the channel mouth.

It is useful that the area of the confluence Channel or the opening channels and the seal in an axially sealed on both sides, the channel area and arranged control area enclosing the sealing area are. For example, this can be done in a conventional way Way in a radial plane around the control member Seals to be limited to the inside of the Interact sealingly together.

The principle described can be used in the control device for the liquid dispenser with two nozzle devices be implemented such that at least in the receiving opening an inlet channel assigned to the liquid inlet and for each nozzle device at least one of the nozzle devices assigned outlet channel open. If at least two channels open into the receiving opening, so it is special useful if the opening into the receiving opening Channels both in the axial direction and in the circumferential direction are offset from each other. This makes it possible to be extreme Avoid skewing the circumferential seals what the design and manufacture of the liquid control device simplified and influenced the function advantageous.

In a preferred embodiment it is provided that a first outlet channel assigned to the first nozzle device and a second one assigned to the second nozzle device Outlet channel and a preferably linear between the Outlet channels arranged, assigned to the liquid inlet Inlet channel are provided and that on the control member in Control area two circumferential seals with oblique peripheral sections are provided, one in the circumferential direction have varying axial spacing. Because of the oblique, non-parallel paths arise between the seals or between a seal with inclined sections and one axial end seal through which the control area can flow or flowable tax areas on the circumference of the tax body. If at a rotational position of the inlet channel and an outlet channel in open into the same, sealed area, these are flow-connected. Conversely, the Inlet duct in one in both axial directions opposite the adjacent outlet channels sealed intermediate area, so the liquid supply is shut off and none of the Outlet channels can carry liquid to the associated nozzle device flow out. This is in connection with the drawings explained in more detail.

In a further development, the first nozzle device is a Spray nozzle device, which is preferably a device for Beam adjustment is assigned, with the help of which, for example a beam expansion and / or a swirl of the under Pressure of escaping water is preferably continuously adjustable is. The second nozzle device can preferably be a Casting shower device, with the help of a comparison for sprinkler device softer, extensive irrigation e.g. of planted beds or flower boxes possible is. If desired, the sprinkler device can Device for beam pattern adjustment to be assigned to for example, to set the size and / or shape of the spray pattern.

A particularly advantageous training that is not only for liquid dispensing devices according to the invention, but in all liquid dispensers with spray heads can be advantageous is that the sprinkler device to create a substantially rectangular Beam pattern is formed. For example, a rectangular shower plate may be provided and / or Shower plate can have a rectangular pattern of Have shower openings. A suitably dimensioned right-angled spray pattern enables particularly advantageous watering generally rectangular flower boxes or the like with high uniformity down to the corner areas, without excessive spilled liquid next to the area to be poured falls.

A preferred further development of the sprinkler device provides that it is used to generate a fanned-out beam pattern is formed, whereby irrigation areas can be generated that are significantly larger than that with nozzle openings provided liquid outlet area of the shower. The fan can be expediently by a fan-like Achieve slanting of the individual shower opening channels. Because the production of a variety of different Directional shower opening channels especially in the Problematic with regard to demoulding during injection molding is, a preferred further development provides that for generation of the fanned jet pattern one with parallel shower opening channels perforated, flexible shower plate used is in a stress-free or relieved state in the substantially parallel shower opening channels has and that this shower plate before or at a Attachment of the shower plate to a shower body preferably uniaxially curved and attached in the curved state becomes.

With this method, the fanning out of the shower opening channels is thus carried out not in the manufacture of the shower plate itself, but only by bending the same during assembly generated. The manufacture of the shower plate is thereby particularly simple and inexpensive. The procedure is especially for single-axis or cylindrical curved shower plates advantageous. Leave with a type of shower plate the most varied by suitable curvatures Simply create a fan-out angle. It would also be possible carry out the assembly so that the shower plate curvature of the mounted shower plate is changeable, making it easy Way an adjustment of the beam pattern by adjusting the Fan-out angle is possible. (??)

Another training that is very beneficial to the Handling particularly highlighted by spraying sprinklers has, provides that the first nozzle device and the second Define the main radiation directions of the nozzle device, which are at an angle to each other, which is preferred is between approx. 45 ° and approx. 90 ° and in particular approx. Can be 60 ° to 70 °. Unlike known solutions, in which two coaxially arranged nozzle arrangements are parallel or have coaxial main emission directions, can by this Training can be achieved that the liquid dispenser regardless of the nozzle device currently used always more or less with the same orientation e.g. held horizontally and can thus be easily guided. So can, for example, a spray nozzle device essentially in extension of a connected hose be aligned, as is also the case with individual spray nozzles for Garden hoses is the case during a sprinkler set up an essentially obliquely downward Main radiation direction can have, causing a sprinkling the flower boxes to be supplied with liquid or the like from above is possible without manual contortion. These characteristics can in all generic liquid dispensing devices regardless of the type of upstream of the nozzle devices liquid control or distributions to be carried out can be used with advantage.

These and other features go beyond the claims also from the description and the drawings, wherein the individual features individually or separately several in the form of sub-combinations in one embodiment of the invention and in other fields be and can represent advantageous designs.

In Fig. 1 is a preferred in vertical longitudinal section Embodiment of a hand-held according to the invention Liquid dispenser 1 shown in the form of a Injection molding shower is designed, that is, a shower in which a spray function and a casting function in one device are united, being between the functions and a Locked position with shut off liquid supply manually can be switched or changed. Such spraying sprinklers e.g. at the front end of a garden hose by means of a suitable quick coupling and are particularly versatile in the house and garden area, for example without retrofitting a garden hose either larger lawns with a spray shower or For example, flower boxes, smaller beds or the like sprinkle with a sprinkler.

The shower 1 has a conveniently designed, about two Fingers wide, made of ABS by injection molding Plastic housing 2, the four functionally separate housing sections 3, 4, 5, 6 with related to each other Has housing spaces.

A rear, inlet-side housing section 3 is in the essentially cylindrical in shape and has a circular shape rear opening into which a plastic hose connection nipple 7 is used, which is liquid-tight with the housing 2 is connected by friction welding. On the hereby formed Liquid feed can be carried out in a known manner e.g. by means of the end of a garden hose is attached to a quick coupling become.

In axial extension of the inlet section of the housing 3 is an injection molding device 10, the main radiation direction 11 coaxial to the cylinder axis 8 of the inlet side Housing section 3 is directed. The injection molding device 10 includes one from the front into the housing section 3 used and by friction welding in the housing wall area with the housing 2 connected, flowable swirl body 12, in its central part an external thread 13 and has a tip 14 at its front end, which at one conical outer section 15, not shown in detail, obliquely to Has swirl grooves extending in the axial direction. Between Thread 13 and tip 14 are radial in the sleeve wall Passage channels 21 provided through the input side inflowing liquid to the outside in the area of Swirl grooves can flow.

On the external thread 13 of the swirl body 12 is an outer Nozzle sleeve 16 screwed on, which is turned by twisting the swirl body 12 axially adjustable and with this a round cord seal 17 upstream of the thread 13 is sealed. The nozzle sleeve 16 has a conical Outer section 15 adapted, outer section from the outside enclosing conical section 18 to which downstream a nozzle channel section 19 with a downstream slightly tapered and then step-shaped widening nozzle channel connects. By building this Spray nozzle device is a device for jet adjustment, especially for adjusting the beam expansion of the bundled beam and the swirl component of the emerging Water created. Because depending on the Axial position of the outer axially adjustable by rotation Sleeve 16 relative to the swirl body 12 fixed to the housing are in Area of interacting conical sections 15, 18 and the swirl grooves both the passage cross section for penetrating Water, as well as the proportion of water changed, that by means of the twist grooves with a twist around the central axis is provided and then through the nozzle channel 20th exit.

Below and slightly set back to the injection molding device 10 is a casting shower device 25 on the lower housing section 5 provided. As if looking at figures together 1 and 2, the housing section 5 is in cross section not round, but rectangular with a diameter of the cylindrical inlet section 3 corresponding width and one generally in the longitudinal direction of the sprinkler extending, about two to three times the length. The Central axis 26 of the housing section indicated by dashed lines 5, which determines the main radiation direction of the spray head 25, stands at an angle of between approx. 60 ° and 70 ° Main axis 8 of the housing upwards.

In the housing opening of the housing section open at the bottom 5, a shower head 27 is inserted and by means of a central screw 28 attached to the housing 2. The shower head 27 has a funnel-shaped bottom 29 which two in at an angle of approx. 130 ° to each other has an inlet connection 30 in the connection region thereof is formed by means of when the shower head is inserted a round cord seal sealed in a cylindrical Section 31 inserted within the housing section 5 becomes. In addition to the nozzle 30 is an outward Projection 32 with an internal thread for the central screw 28 trained. The ledge protrudes outwards over the level out, in which the bottom 29 forms, at an angle to each other aligned sections end.

The shower head 27 is outwardly by a assembled, cylindrical curved, rectangular shower plate 33 completed in a regular pattern a plurality of shower opening channels 34 are provided, which are generally perpendicular to the curved shower plate surface are aligned and thereby a fanning angle of generate approximately 20 °, for example. The shower plate is in its edge area with the cylindrically curved, rectangular Outer edge of the shower head by ultrasonic welding connected liquid-tight.

A particularly advantageous method, such a fanning out to achieve shower opening channels 34 in it, first a level made of resiliently flexible material Shower plate with shower opening channels running parallel to each other manufacture what is both in tool making, as well as no special during demolding Problems. When the sprinkler insert is completed then the still flat shower plate is cylindrical on the curved rectangle edge of the shower head placed and the free protruding ends in the direction of the inlet nozzle 30 with generation a cylindrical curvature of the shower plate 33 is bent, until they rest on the edge of the shower body. In this curved state, the ultrasonic welding takes place tool-free, solid and liquid-tight connection of shower plate and shower body. The sprinkler can deviating from the drawn embodiment, also adjustable his.

An essential element of the injection molding shower shown is a manually operable liquid control device 40 for Control of the liquid flow between the liquid inlet 7 and the nozzle devices 10, 25. The control device 40 is preferred as a 3/3-way valve with a rotatable control element trained like a chick and works so that by rotating the control member 41 either only the sprayer 10 or the spray head 25 in operation or Liquid supply to both showers can be shut off. Farther allows the control device between these extreme positions a continuous adjustment of the flow rates to the Nozzle devices 10, 25, for these settings likewise only the control member 41 into a suitable one Must be turned.

The one which can be seen particularly well in FIGS. 2 to 5 Control device 40 has a control device housing 42, by the one piece with the housing sections 3, 4 and 5 formed cylindrical housing section 6 is formed becomes. The controller housing 42 is in the cutting area of the three adjacent housing sections 3, 4, 5 and adjoins each of these housing sections. Internally of the controller housing is one to an axis 43 rotationally symmetrical, cylindrical receiving opening 44 formed, which, as can be seen in Fig. 2, the housing 2 perpendicular to the sectional plane of FIG. 1 or to the axis 8 enforced.

In the cylindrical housing wall there are three axially and in Essentially offset circumferential direction circular openings or channels 46, 47, 48 are provided. On Inlet channel 46 connects the receiving opening with the Inside the inlet-side housing section 3 and thus with the liquid inlet 7. Via a first outlet channel 47 is the receiving opening 44 in connection with the Spray device 10 associated interior of the housing section 4. A second outlet channel 48 connects the receiving opening with the inside of the lower housing section 5 or the interior of the cylinder section 31 and leads to Pouring shower device 25. As is particularly good in FIGS. 2 to 5 it can be seen that the axially successive channels lie offset in each case in the circumferential direction by approx. 90 °, where the dislocation distance is larger than the channel diameter is and corresponds approximately to three times the channel radius. The Inlet opening 46 lies centrally on one of the two Outlet openings 47, 48 connecting spiral line. A liquid-conducting Connection between the housings 3, 4, 5 only exists over the interior of the controller housing through the assigned channels, so that through Connection of the channels or mutual sealing of the channels 46, 47, 48 the described function of the control device is achievable.

The comfortably from an axial side of the receiving opening 44 in this usable and from the other side with a holding member 39 can be secured against being pulled out of the receiving opening Control member 41 has a one-piece made of suitable plastic manufacturable control body 50, on one Axial end a toggle section 51 with an end plate 52 and one running across the outside of the end plate Handle bar 53 is shaped. At the opposite end is one Opening for inserting the one rotating with the control element Holding member 39 provided. On the handle bar 53 opposite Side of plate 52 is coaxial with one Axis of rotation 43 of the control member is essentially cylindrical Seal carrier section 55 formed, the Outside diameter is about 20% to 45% less than that Inner diameter of the receiving opening 44. On the outside of the seal carrier section are radially projecting webs 56 formed together with the outside of the seal carrier portion or the end plate 52 grooves for round cord seals form when the control element is inserted with the inside 49 of the receiving opening 44 as a sealing surface work together.

Immediately adjacent to the end plate 52 and on the opposite End of the seal carrier section is in each case an axial circumferential in a radial plane of the control member End seal 57 and 58 provided. As the radial plane here a plane perpendicular to the axis of rotation 43 of the control member designated. These seals are outside of the with channels 46 to 48 provided area, seal this in the axial Direction outwards and delimit one between them partially flowable control area 61.

The webs 56 are in the control area by suitable guiding Sealing grooves created, the inlaid in Figures 3 to 5 partially indicated by dashed lines, in Circular cord seals or O-rings closed in the circumferential direction impose a course in which the orbiting Seals in the area of oblique peripheral sections across run a radial plane of the control member. In which shown 3/3-way valve (in the between the three connection channels 46, 47, 48 three extreme switching positions are possible) are two such oblique seals 59, 60 with oblique, not parallel course provided. The gag section 51 facing first seal 59 runs obliquely, that in the first open position shown in FIG Control device 41, the operation of the spray device 10 corresponds to the inlet duct 46 and the first outlet duct 47 in a common, through the seal 59 to the second Outlet channel 48 sealed and limited connection area 62 open out while the second outlet channel 48 is outside of the connection area 62. The connection area 62 here is a closed one in the circumferential direction Channel whose axial width through the circumferential direction varying axial distance between seal 57 and seal 59 determined and its radial expansion by the radial distance between the outside of the cylinder portion 55 and the inside 49 of the receiving opening is determined. The Flow cross section is expediently chosen here so that all desired flow rates even in maximum operation are transportable. The slope of the first seal 59 is in particular characterized by an axially extending characterized approximately sinusoidal bulge, which in 3, the inlet opening 46 encloses the side facing away from the gag.

If the gag, starting from the first shown in Fig. 3 Flow position to the syringe rotated counter-clockwise is, the passage cross-section on Inlet duct 46 is continuously reduced in that the first seal 59 is moved across the mouth opening, a part of the inflowing liquid continues to Outlet 47 and the rest in an area 63 between the Seal 59 and the seal 60 is passed. After rotation is the locking position of the control member shown in Fig. 4 reached, in which the inlet channel 46 in an approximately lens-shaped region 63 opens out to the first outlet 47 through the first seal 59 and towards the second outlet 48 is sealed by the second seal 60. The one at the inlet duct Incoming water under pressure can therefore none of the exits or to any of the nozzle devices get and the liquid supply to the spraying sprinkler is interrupted overall.

When the control member continues to rotate counterclockwise from the blocking position shown in Fig. 4 in the direction of in Fig. 5 second open position is first a small part of the inlet opening 46 in the direction of the outlet opening 48 released by a sloping section of the second Seal 60 slides obliquely over the mouth cross section. This can be used for continuous quantity regulation in the manner described of the inflow to the sprinkler can be used. Becomes finally the second open position shown in FIG. 5 set, starting from the first open position (Fig. 3) by rotating the locking member by 180 ° against the Clockwise results, the inlet channel 48 opens into one Connection area 64, which is opposite the first outlet 47 is sealed by both seals 59, 60 and the Inlet channel 46 with the second outlet channel 48 and thus the Inlet 7 connects to the shower head device 25.

The assigned the full passage positions (Figures 3 and 5) Rotational positions can be set with limit stops be what the toggle section 51 facing the housing Projection 65 can be provided, which in a corresponding semicircular groove engages on the outside of the housing.

This is based on a preferred embodiment of a 3/3-way valve operating principle explained for an injection molding shower 1 the liquid control device 40 is also to other directional valves with more or less than three connections and more or less than three switch positions transferable by using an appropriate number of helical seals is provided with a corresponding number of Interact connection channels according to the principle described. The use of such new directional control valves is not limited to spraying sprinklers. According to the invention Liquid control devices can also advantageously be used in other areas of fluid control especially where easy handling and a reliable function is desired. Since in accordance with the invention Control devices on the side of the control device housing only a rotationally symmetrical, in particular cylindrical Opening must be provided, the production of suitable housings of such control devices both at Injection molding process as well as for example in the case of material removal Procedure can be very inexpensive. The possibly higher tool and / or manufacturing costs for possibly irregularly shaped control elements with the appropriate seal guide may initially be higher than conventional ones Facilities. Due to the universal applicability such control bodies are, however, in large numbers be producible, so that there are higher tools Amortize initial investments very quickly.

The flow-controlling elements of the control device can structurally and functionally completely independent of the be flow-shaping elements of the nozzle device, whereby for the nozzle devices and the control device constructive scope. A control device according to the invention can also be used in other facilities be used advantageously, in which the described Control functions are desired or required, e.g. at All kinds of distribution facilities Advantages resulting from the special features of the nozzle equipment result (e.g. their angular position to each other or the Rectangular radiation of the sprinkler system) independently of the control device according to the invention also together with other control devices, e.g. with slide valves or the like
