Description

Heater for On-Demand Hot Water Dispensing
FIELD OF THE INVENTION
This invention relates to a water heater, particularly one for use in a hot water dispenser or a beverage machine.
BACKGROUND OF THE INVENTION
Apparatuses for heating and dispensing hot water, typically used for preparing hot drinks, are known.
For example, US patent 7,596,306 discloses a combination water dispenser with heating mechanism that includes a reservoir holding water that is automatically replenished. The reservoir has a controlled water outlet for dispensing the water. An electric heating element is disposed in the reservoir with an associated indicating means for indicating the activation and deactivation of the heating element that is included on the dispenser. When a user actuates the dispenser the heating element and the indicating means are simultaneously activated. A temperature regulator that is responsive to the temperature of the water monitors the temperature of the water during the heating of the water. The reservoir heating element is automatically deactivated upon receiving a signal from the temperature regulator.
SUMMARY OF THE INVENTION
The present invention provides a water heating device for use, for example, in an on-demand hot water dispenser. The term "hot water" in the context of the present invention refers to a water temperature typically exceeding 85°C, 90°C or at times exceeding 95°C.
Provided by the invention is a water heating device. The device comprises a water reservoir with a water inlet; a heating compartment defined within the reservoir and in water flow communication therewith; a heating element disposed within the heating compartment for heating the water therein; a communication duct leading from within the heating compartment to an expansion chamber; a pressure releasing vent in said expansion chamber; and a water outlet duct from said expansion chamber.
By an embodiment of the invention, the reservoir has an entry compartment, which defines a space surrounding the heating compartment. The reservoir has typically heat-insulating walls.
The heating compartment typically defines a relatively small confined space. According to an embodiment of the invention, the heating element is an electric heating element. According to an embodiment of the invention, the heating element occupies a significant portion of the heating compartment and has a power output such so as to permit it to rapidly heat the water within this compartment. Rapid heating according to one embodiment refers to heating the water within said compartment to a hot water temperature within a period of several seconds, typically less than 20, 15 or even less than 10 seconds. According to another embodiment, rapid heating means heating the water while it is being dispensed and thus while it flows through said compartment and eventually out of the water outlet; such flow being typically at a rate applicable to hot water dispensers, namely at rate of at least 10, 15, 20, 30, 40, 50 , 75 or even 100 ml/sec.
According to an embodiment of the invention, the heating compartment is substantially a vertically oriented cylindrical enclosure, having walls typically made of metal and/or polymeric material. The heating element according to an embodiment of the invention is a spiral coil. When disposed in a cylindrical heating compartment, the spiral coil's axis is typically, albeit not exclusively, oriented so as to be parallel and often coaxial to the axis of the cylindrical heating compartment.
A temperature probe may be disposed within the heating chamber for temperature monitoring and/or control. At times more than one temperature probe may be included, for example one in the heating chamber and another in one or both of the expansion chamber and the entry compartment for a more accurate temperature monitoring and/or control.
The expansion chamber is typically situated above the water reservoir. The communication duct leading to the expansion chamber may be made to be coaxial with the opening of the water outlet duct. According to one embodiment of the invention, the opening of the communication duct within the expansion chamber is opposite and in close proximity to the opening of the water outlet duct. According to one embodiment of the invention, the diameter of at least a portion, typically the upper portion of the communication duct, has a narrower diameter than the water outlet duct; and consequently, there is a pressure differential between the heating compartment and the expansion chamber. Therefore, the vapor (steam), that might build-up, will form in the entire expansion chamber and would not exit through the water outlet duct. This ensures flow continuity that may have been disrupted otherwise. The pressure valve ensures release of vapor formed in the expansion chamber. In accordance with an embodiment of the invention, the outlet of the pressure release vent is in flow-communication with a hot water dispensing tubing, which is linked to the water outlet duct.
The water heating device may be used for an on-demand water dispensing apparatus. In such an apparatus, the water heating may be continuous and controlled by a temperature control mechanism. According to such an embodiment, a volume of water is heated in a batch-type manner and once heated the hot water may be dispensed. In addition or in the alternative the device may be used with an on-demand heating arrangement, whereby heating is actuated when water is dispensed to heat the water as it flows through the heating compartment.
As may be appreciated, through convection or other heat exchange mechanism, heat generated within the heating compartment is transported also to the rest of the reservoir. The larger heated body of water ensure that heat is maintained over time period and thus more rapid heating the water to yield hot water for dispensing when need arises.
BRIEF DESCRIPTION OF THE DRAWINGS
In order to understand the invention and to see how it may be carried out in practice, embodiments will now be described, by way of non-limiting example only, with reference to the accompanying drawings, in which:
Fig. 1 is a top perspective view of a device according to an embodiment of the present invention.
Fig. 2 is an exploded view of the device of Fig. 1.
Fig. 3 is an isometric longitudinal section through the device of Fig. 1.
Fig. 4 is a longitudinal cross-section of the device of Fig. 1 along line A-A. DETAILED DESCRIPTION OF EMBODIMENTS
The drawings show a device according to an embodiment of the invention which may be installed in a beverage-preparation machine or a hot water dispensing machine, not shown, which may provide hot water for use upon demand. As will be appreciated, this is only one embodiment of the water heating device within the scope of the invention, as defined above and in the appended claims.
Device 10, shown in Fig. 1, depicts a water reservoir 20 with a water inlet 22. The device 10 has a body 24 with heat insulating walls 26, defining a water entry compartment 28. The device has a base 30, which is tightly screw-fitted to the body 24, through screw coupler 32. A gasket 34 is positioned between a bottom face of water reservoir 20 and a top face of base 30 in order to provide a water-tight engagement with screw coupler 32. The water inlet 22 leads into the entry compartment 28 for feeding water therein. In one embodiment of the invention depicted in Fig. 1, the water inlet 22 is at the side of the water reservoir 20. In another embodiment depicted in Fig. 3, a water inlet 22' extends through the top cover element 72, into water entry compartment 28.
A cylindrical body 40, within the reservoir, typically made of metal, defines a heating compartment 42. A plurality of lateral openings 46 are disposed along the circumference at the bottom portion of the walls of cylindrical body 40. Through these openings water communicates between entry compartment 28 and heating compartment 42.
Spiral electric heating element 50, defining a generally cylindrical shape, coaxial with walls 40, is disposed within the heating element and power-supplied by electrical couplings 36. Given its structure and the tight arrangement of its coils, it has a large heating capacity to permit rapid heating of the water within the heating compartment 42.
Disposed within the heating compartment is temperature probe 52 extending down from the top of the device; and which is typically part of a temperature control mechanism (not shown). The temperature probe 52 is held in place by a heat insulating, fastening member 54.
Formed on top of the reservoir is expansion chamber 60. Linking duct 62 provides flow communication between heating chamber 42 and expansion chamber 60. The expansion chamber 60 is provided with a water outlet 66, extending outwards from a top cover element 72. The bottom portion 68 of outlet duct 66 is opposite, substantially coaxial and in close proximity to the upper end 64 of linking duct 62. As can be seen, outlet duct 66 is of a larger diameter than duct 62; and accordingly there is a pressure drop, whereby the pressure within the expansion chamber is lower than the pressure within the heating compartment. Consequently, vapor will build up in the expansion chamber, released throughout the chamber and such vapor can then exit through vent opening 80. By some embodiments, the arrangement is such that any released vapor is fed into the tubing that transports hot water and linked to the outlet duct (not shown). A bleed aperture 86 is provided between the chamber 60 and the compartment 28. A top cover element 72 is fastened to the expansion chamber 60 by a plurality of screws 76. A gasket 74 is positioned between a top face of the expansion chamber 60 and the bottom face of the top cover element 72, thereby providing a water- and/or steam-tight engagement.
