A kind of water drinker cold tank
Technical field
The utility model relates to water drinker cold tank, especially a kind of water drinker cold tank that uses inflation type evaporator to freeze.
Background technology
At present, producing of drinking machine cold-water generally has electronic refrigerating container and the cold tank dual mode of compression mechanism, and wherein the efficient because of compressor cooling is higher, generally uses in high-end water dispenser.The direct refrigeration of cold tank is to be realized by the evaporation tube evaporation endothermic in the compressor refrigeration system.The cold tank of existing water dispenser normally by evaporation tube directly on the outer wall of cold tank and be welded and fixed, this can cause some shortcomings and problem.Take up on the one hand and welding procedure complicated, the production efficiency of cold tank is lower, causes easily on the other hand evaporation tube and cold tank skin to have the gap, add that evaporation tube and cold tank skin are that line contacts, thereby heat transfer area is little, thereby reduces the refrigerating efficiency of cold tank.
Chinese patent CN201020173846.2 drinking water machine evaporator discloses a kind of roll-bond evaporator preparation method that can be used for water dispenser, and roll-bond evaporator often is aluminium sheet inflation type evaporator or aluminium zinc-aluminium composite plate roll-bond evaporator, and it is shaped as panel.The heat transfer area of roll-bond evaporator is large, and heat conduction efficiency is high, and refrigerating speed is fast, has been usually used in refrigerator and the refrigerator-freezer at present.Because whether the arrangement of roll-bond evaporator and water drinker cold tank to being convenient to installation and cold transmission is had considerable influence, and still there is not the technical scheme that can effectively address this problem in the prior art.
Summary of the invention
The purpose of this utility model provides a kind of water drinker cold tank that uses roll-bond evaporator, and the evaporimeter that mainly overcomes water drinker cold tank in the prior art is made installation question, promotes simultaneously cold tank refrigeration performance.
For realizing that the technical scheme that this purpose adopts is: a kind of water drinker cold tank includes cold tank (1) and outside lagging casing (2) thereof; It is characterized in that it comprises that also described roll-bond evaporator (3) assembling is adjacent to the surface of cold tank (1) be used to the roll-bond evaporator (3) that makes the water refrigeration in the cold tank (1).
Above-mentioned roll-bond evaporator (3) comprise around circular cylinder (31) and muffler (32), be provided with annulated column joint face (311) at the two ends of circular cylinder (31).
On the two sides of above-mentioned annulated column joint face (311), correspondence is provided with through hole, adopts by described through hole to be threaded or to rivet.
Perhaps a face of annulated column joint face (311) is provided with buckle, and another face is provided with draw-in groove, carries out clamping by cooperatively interacting of buckle and draw-in groove.
Perhaps weld or this circular cylinder (31) as closed loop of roll-bond evaporator (3) on annulated column joint face (311) two sides, circular cylinder (31) and/or cold tank (1) are provided with certain inclination angle, and roll-bond evaporator (3) carries out interference fit with cold tank (1) and installs.
Perhaps roll-bond evaporator (3) is the part of cold tank (1), is generally tank skin bottom and/or bottom, makes evaporation tube by blowing-up technology, and cold tank (1) is integrated with roll-bond evaporator (3).
Above-mentioned lagging casing (2) is formed by the first lagging casing (21) and the second lagging casing (22) combination merging.
Described the first lagging casing (21) is provided with fan-shaped bump (211), and the second lagging casing (22) is provided with corresponding recess (221).By the convex-concave design, can make elongated muffler (32) needn't pass aperture, thereby realize Fast Installation.
The outside of above-mentioned lagging casing (2) is provided with for the wrapping stopper slot of strap (20).
Above-mentioned lagging casing (2) material is insulating foam.
The beneficial effects of the utility model are, because roll-bond evaporator is provided with circular cylinder, can assemble the surface that is adjacent to cold tank, perhaps roll-bond evaporator is a part that consists of cold tank, therefore, can guarantee preferably fitting tightly of roll-bond evaporator and cold tank, compare to cold tank with the welding evaporimeter of prior art, install simplyr, can realize manufacturing rapidly and efficiently.In addition because having guaranteed face contact closely, thereby increased refrigerating efficiency and the cooling quality that heat transfer area has also improved cold tank.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Embodiment 1:
As shown in Figure 1, the utility model includes cold tank 1, lagging casing 2 and roll-bond evaporator 3 with the water drinker cold tank of roll-bond evaporator, and described roll-bond evaporator 3 assemblings are adjacent to the surface of the bottom of cold tank 1, as shown in Figure 3; And outer wrap has lagging casing 2 to be used for being incubated.
Such as Fig. 2~shown in Figure 6, roll-bond evaporator 3 comprise around circular cylinder 31 and muffler 32, be provided with annulated column joint face 311 at the two ends of circular cylinder 31.On the two sides of annulated column joint face 311, correspondence is provided with through hole, as shown in Figure 3, in order to be threaded or rivet.
As shown in Figure 2, lagging casing 2 is formed by the first lagging casing 21 and the 22 combination merging of the second lagging casing.Described the first lagging casing 21 is provided with fan-shaped bump 211, and the second lagging casing 22 is provided with corresponding recess 221.By the convex-concave design, can make elongated muffler 32 needn't pass aperture, thereby realize Fast Installation.The outside of above-mentioned lagging casing 2 is provided with for the wrapping stopper slot 20 of strap.Lagging casing 2 materials are insulating foam.
Embodiment 2:
As shown in Figure 7, the difference of present embodiment and embodiment 1 is that the circular cylinder 31 of roll-bond evaporator 3 does not have annulated column joint face 311, itself just is the circular cylinder 31 of closed loop.Circular cylinder 31 is provided with certain inclination angle with cold tank body 1, when roll-bond evaporator 3 promotes upward from cold tank body 1 bottom, and can be more and more tighter between the cold tank 1.Thereby cooperate rapidly installation by interference fit.
Embodiment 3:
The difference of present embodiment and embodiment 1, embodiment 2 is, there is not independently roll-bond evaporator 3, but with roll-bond evaporator 3 as the part in the cold tank 1, be generally tank skin bottom and/or bottom, make evaporation tubes by blowing-up technology, thereby do not need assembling, cold tank 1 itself is exactly the structure member that is integrated with roll-bond evaporator 3.
Above-mentioned three kinds of embodiment have specifically used the technical solution of the utility model preferably, but during concrete practicing, are not limited to can adopt other connected mode with above-mentioned three kinds.Protection scope of the present invention is not limited to this, and those of skill in the art are any to be included within protection domain of the present invention based on non-material change on the technical solution of the present invention.
