Description

Comprise the refrigerating plant that to extract drawer out

Technical field

The present invention relates to a kind of refrigerating plant, especially a kind of household refrigerating device, housing with closed storage room and the pallet that can extract out from storeroom.

Background technology

Refrigerating plant is known; Be installed with in the storeroom of refrigerating plant the inside lid and when be arranged at pallet storeroom place restrictions on the position time, said lid on pallet, extend a small distance and make to a great extent said pallet inside and around storeroom separate.Like this, the air exchange of restriction storeroom and pallet the inside.If the chilled goods that is stored in the pallet such as fresh, unpacked fruit, vegetables or the like gives out moisture; In pallet, can form the air humidity higher, during operation because the air in the storeroom constantly contacts with the cooling surface of evaporimeter and dewaters than storeroom surrounding environment.The water evaporates of high air humidity minimizing chilled goods makes that these chilled goods can the fresh-keeping long period in the pallet.

Yet the air humidity that have a mind to increase by means of lid can not be regenerated reliably and can not always be reached the degree that needs.The reason hypothesis that this situation occurs is the air flow behavior in the storeroom.A small amount of continuous air flow through the gap between pallet and the lid is enough to prevent in pallet, form the air humidity increase.The intensity that whether produces the effect of such air stream and air stream depend on chilled goods in storeroom stacking and placing restrictions on the position and extracting the inexactness of the guiding of pallet between the position out.

Summary of the invention

The objective of the invention is to propose a kind of refrigerating plant that to extract pallet out that has, in said refrigerating plant, can in said pallet, reach and keep high air humidity reliably.

A kind of refrigerating plant especially is interpreted as a kind of household refrigerating device, that is to say a kind of refrigerating plant that is used for housework, such as, for example refrigerator or refrigerator-freezer combination.Said refrigerating plant can be the refrigerating plant of frost-free, and wherein cold air blows into storeroom so that can cool off its storeroom from the evaporimeter chamber.

Said purpose is through a kind of refrigerating plant; Especially a kind of household refrigerating device is realized; Said refrigerating plant have storeroom and can be in said storeroom place restrictions on position and pallet from moving between the position that said apotheca is extracted out; When being in when placing restrictions in the position, said pallet tegmentum subcovering, said lid and pallet have the sealing surfaces of complementation overlapping when placing restrictions on the position.Through said around the inner sealing of storeroom and pallet can prevent that undesired moisture from leaking from said pallet.

If said pallet has base plate and around the wall of said base plate, the sealing surfaces of said pallet can be advantageously be made up of the top edge of said wall.

For fear of when said pallet is extracted out, having harmful friction between the said sealing surfaces, said sealing surfaces is advantageously tilting with the extraction of said pallet direction in the opposite direction.

If said lid can move on vertical, although in said pull-out location with place restrictions between the position, the guiding of said pallet is inaccuracy perhaps, and the contact fully between the sealing surfaces said pallet and lid can be guaranteed.

When said pallet leaves resting position, when this mobile lid when being in the pallet of placing restrictions on the position and advantageously contacting, said movably lid rises from resting position.

When said pallet is inserted into or when needing, said pallet arrive said place restrictions on the position before, said lid begins to rise from said resting position.Therefore can avoid said lid and sealing surfaces pallet mutual friction mutually on the part of pallet stroke.In order to make this section stroke partly keep short as far as possible, if the sealing surfaces of said lid is more precipitous than placing restrictions in the position in said resting position the time, this is useful.

Said lid preferably is suspended on the plate of separating said storeroom.Aspect said plate, said plate can be used in and prevents chilled goods.And, when using known refrigeration device housing, said lid be assemblied in the refrigeration device housing divided portion on and be installed in the said storeroom, this is convenient to embodiment of the present invention economically.

For said lid is kept being assembled to gap on the said plate, plate and lid especially can enough interlocking hooks and the hole assembling of eye shape.

And if said lid can be located in the position of placing restrictions on the said pallet of blow-by in the position of said pallet, this is useful.If desired, between said pallet and storeroom, can carry out air exchange, especially remove moisture condensation that said chilled goods distributes on the inwall of pallet and be collected in the danger on its base portion.

In the unsealed position of said lid, cross the inside of said pallet in order to guarantee not interrupted circulation of air, said lid preferably do not touch at any point with sealing surfaces pallet.

Serviceably, said pallet can have the sidewall of convergence (converge) on the rightabout of extracting direction out.On the one hand, these allow to optimize the refrigerating plant volume inside and use, and the sidewall of said refrigerating plant is according to equally generally convergence backward of manufacturing technology.On the other hand, when said pallet was inserted in the said storeroom, the sidewall of said convergence was convenient to the joint of pallet and lid.

For accurately each other location tray and lid, said lid serviceably is provided with ledge, and said ledge laterally defines the sealing surfaces of said lid and makes sidewall fringing on its outside of said pallet.

Description of drawings

Other characteristic of the present invention and advantage will show from the exemplary embodiment of describing with reference to the accompanying drawings, wherein:

Fig. 1 has shown the cross-sectional schematic with the refrigerating plant that can extract pallet out of the present invention;

Fig. 2 has shown the perspective diagram of lid and pallet;

Fig. 3 has shown the decomposition view of pallet according to another embodiment of the present invention, lid and plate, and wherein, said lid is suspended on the plate; And

Fig. 4 has shown the perspective view of the slide block that is used to adjust said lid height among the embodiment shown in Fig. 3;

The specific embodiment

Fig. 1 has shown the cross sectional representation of the household refrigerating device of frost-free, and said refrigerating plant has main body 1 and door 2, and the door 2 that shows among the figure is opened, and door 2 seals into interior chamber.In known mode, main body 1 comprise plastic inner container, the outside wallboard of deep-draw and be filled in said internal container and said outside wallboard between the insulating materials of wall of said main body.Depend on the deep-draw manufacturing technology, the sidewall of said container is not accurately parallel, but said sidewall is restrained towards rear wall a little.

The inside of said internal container is divided into pallet 3 that gets into 4 li of evaporimeter chambers below the lid that is installed in said main body and the storeroom 5 that is used to store chilled goods.Storeroom 5 usefulness level boards 6 are separated, and said plate especially may be embodied as glass plate so that near base portion, be formed for extracting out the shelf 7 of pallet 14.

It is indoor that evaporimeter 8 and fan 9 are contained in evaporator chamber in known manner.When fan 9 work; Fan 9 is drawn into evaporimeter chamber 4 through the opening 10 of the leading edge of pallet 3 with the air in the storeroom 5; In evaporimeter chamber 4; Said air contacts with evaporimeter 8 and is cooled, and forces said cooling air to enter into distribution duct 11, distribution duct 11 in the rear wall of main body 1 to extending below.A plurality of steam vents 12 of distributed lines 11 at the differing heights opening in storeroom 5; Minimum steam vent 13 in the lower aperture of plate 6 in shelf 7.Contents in the pallet 14 mainly through the air stream cooling from steam vent 13, cross the passage 16 that between plate 6 and lid 15, extends and scatter by circulation of air, lid 15 sealing pallets 14.

In Fig. 1; Pallet 14 leads on telescopic rail 19, and pallet 14 is presented in two positions, dots on the one hand to be arranged in the position of placing restrictions on that is inserted into shelf 7; On the other hand; Represent to be positioned at the pull-out location with solid line, in the pull-out location, whole pallet 14 is positioned at the front of the leading edge of plate 6.

In Fig. 2; Injection-molded plastic pallet 14 shows that with the mode from the perspective oblique view of following observation plastic pallet 14 roughly has the shape of flat cuboid, and upside is opened; Have the base plate 20, antetheca 21 of level, a little than low rear wall 22 of antetheca 21 and the sidewall 23 that connects

wall

21,22; Sidewall 23 has top edge 24 and step 25, and top edge 24 tilts towards rear wall 22 equably, in the telescopic guide 19 that step 25 receives separately one.Yet two telescopic guides 19 must align in parallel with each other, and sidewall 23 is at least above step 25, and the convergence towards the rear portion a little is corresponding to the convergence point of the sidewall of body 1.

Lid 15 slave plates 6 are via interlocking

hook

33,34 and

eye shape hole

29,30, and each in them lays respectively near four turnings of plate 6 or near four turnings of lid 15.Each

shape hole

29,30 has vertical slots 31, and

hook

33,34 is bonded in the slit 31 with having vertical gap, thereby lid 15 in fact also can be vertically but not flatly move.In Fig. 1, lid 15 shows and is arranged in resting position, and wherein, lid 15 can't help pallet 14 and supported, but only remains on plate 6 places.In the

hook

33,34 each all is positioned at the lower end of slit 31.Like what can see, this resting position ratio is low in the path of the top edge 24 of the sidewall of placing restrictions on pallet 14 in the position 23 that inserts, and in resting position, the gradient of lid 15 is also more precipitous than the gradient at edge 24.Because the leading edge 17 of lid 15 is higher than the top edge of rear wall 22, when pallet 14 was pulled in the shelf 17, pallet 14 contacted with lid 15 in lid 15 slid underneath and beginning easily, and only before raise it soon in the position of placing restrictions on that arrives insertion.Because the gradient of lid 15 is more precipitous than edge 24, has only the top edge of rear wall 22 to contact lid 15 earlier, and follow travelling forward continuously of pallet 14, lid 15 to begin to tilt.When the gradient that only is lifted to it at said lid at Background Region is equivalent to the gradient of top edge 24 of sidewall 23, on the edge of 24 and lid 15 between have contact fully.When the position is placed restrictions in the insertion that has arrived it when the said drawer of extracting out; The top edge contact lid 15 of all

walls

22,23,24 of pallet 14; Thereby the inboard of said pallet is roughly airtight, and in case the form of ventilating under any circumstance all seal.

Mentioned that as above Fig. 2 has also shown from the perspective oblique view of the lid 15 of following observation.As the sidewall 23 of pallet 14, the incline of lid 15 also on the skew extends each other, thereby prone web 18 extends along the incline and the back edge of lid 15, places restrictions in the position in the insertion of pallet 14, and web 18 is positioned near the

wall

23,24 of pallet 14.Because the distortion of pallet 14 or the distortion of lid 15; If under the load of the chilled goods that for example in pallet 14, holds; The top edge of

wall

21,22,23 does not place on the horizontal edge zone 43 of lid 15 along their whole length hermetically, and web 18 also prevents the inner ventilation of pallet 14 reliably.The central area 44 of the lid 15 that is surrounded by fringe region 43 is outwardly-bent a little to improve the rigidity of lid 15.

If the contents of pallet 14 send a large amount of moisture, water can condense on lid 15 and drip back in the pallet 14.Because their maintenance quality of the aqueous water that contacts with chilled goods infringement, this humidification again should be avoided as far as possible.Therefore; If lid 15 in no case places on the pallet 14 hermetically, but if desired, also can account for away from the position of pallet 14; In this position; Air flows out steam vent 13 through the inside of pallet 14, rather than flows out steam vent 13 through passage 16, and thereby can carry unnecessary ambient moisture.In Fig. 3, show having pallet 14, lid 15 and keeping extracted out the drawer of the plate 6 of lid 15 of meeting this requirement with the form of decomposition view.Here, the plate 6 of safety glass in its preceding and back edge by plastics or metal,

wide part

27,28 fringings of two types processed of aluminium especially.In the eye shape hole 29 of the wide part 27 of each anterior type each all has slit 31, and in this embodiment, slit 31 is inclined upwardly towards rear wall.

Said lid mainly comprises plastic plate; As shown in the figure; It can be smooth, perhaps like the instance of the lid among Fig. 2, can be separated into the middle section 44 of smooth fringe region 43 and protrusion; Each fringe region 43 of said plate can form sealing surfaces, and sealing surfaces can be placed restrictions on the top edge that is positioned at pallet 14 in the position in the insertion of pallet 14.In this case, the web 18 of the exemplary embodiment of Fig. 2 is reduced into the finger piece 45 of downward sensing on two inclines of lid 15, and in the rear edge complete obiteration of said lid.On the top side of said plate, the muscle 32 that projects upwards is molded integratedly to form rectangular frame.The antemarginal muscle 32 that adjoins said plate carries two hooks, and the free end of hook is formed by the sweptback tongue that projects upwards 33 respectively.Under assembled state, each tongue 33 extends through the opening separately in eye shape hole, rear portion 30.The preceding turning of adjoining lid 15, the angled slots 31 in pin 34 engage front eye shape hole 29 under installment state.Form is that the guide-contour of slit 35 stretches on the degree of depth of body 1 and width, on the leading edge of lid 15, extends.

In Fig. 4, show slider 36 with the form from the perspective oblique view of following observation, slider 36 breech lockeds are forwardly on the wide part 27 of type and removable on its longitudinal direction.Slider 36 comprise three integral types, be similar to the wide part of asymmetrical U-shaped type, the

wall elements

37,38,39 that connects at the place, right angle, under assembled state, these wall elements are in its preceding, top and the wide part 27 of rear side pinching.Handle portion 40 is outstanding forward from wall elements 37, and slider 36 can utilize handle portion 40 to be clamped easily to move it.Finger piece 41 is parallel to wall elements 38 and extends below the downside of the wide part 27 of type under assembled state, finger piece 41 is molded on the opposition side of wall elements 37 integratedly.Under installment state, end sections 42 downwarpings of finger piece 41 are with the slit 35 of engage cover 15.The length of this end sections is at least corresponding to the vertical motion free degree of the lid of being confirmed by the vertical extension of slit 31 and tongue 33 15.End sections 41 is bonded on and has limited slider 36 in the slit 35 and force the lid 15 on the depth direction of body 1, to move along the freedom of motion of the wide part 27 of type and it, and said motion can be coupled in the lateral displacement of slider 36.Pin 24 is bonded in the

lug

29,30 with tongue 33, and this is restricted to the path of rising with the freedom of motion of lid 15 again with receding, thereby lid 15 motion inevitable in the motion on the depth direction and on vertically interrelates.

That is to say; If being arranged in, slider 36 places restrictions on the position; Finger piece 41 in placing restrictions on the position in abutting connection with the right hand end of slit 35; Lid 15 is arranged in the position of the drawer 7 that sealing can extract out, and in this position, it places on the sealing surfaces of the pallet 14 that the top edge by

arm

21,22 and 23 forms fully and closely seals pallet 14.Following, rearward end and the tongue 33 that pin each in 14 is positioned at slit 31 is minimum through the joint of the opening in eye shape hole 30.

If said slider is placed restrictions on the position from the right hand and is moved to the left a little, lid 15 moves backward and moves up owing to pin 34 and tongue 33 are bonded in the

shape hole

29,30 simultaneously.Because web 18 disappears in the back edge of said lid; The little motion of slider 36 is enough to open the gap of on the whole width of the rear wall 22 of pallet, between pallet 14 and lid 15, extending, and dry cold air can get into the pallets 14 from distribution duct 11 via this gap.

If slider 36 is located at opposite the placing restrictions in the position on the left hand end of slit 35, lid 15 arrives the position of maximum lift.In this position, finger piece 45 also has been eliminated with the overlapping of sidewall 23, and air can get on all peripheries of said pallet and leave.

The extension of slit 35 on the width of body 1 is greater than its extension on depth direction.It is more little that the sensing more extreme or slit 35 of said ratio departs from said width, shown in the self-locking of guide strong more, said guide overcomes the gravity that acts on lid 15 and keeps it in the top edge a distance apart from pallet 3.Because this self-locking effect, lid 15 all is stable in each position of slider 36.
