Implement cold water tank of the present utility model and water dispenser, has following technique effect: in the utility model, temperature-sensitive pipe and evaporation tube connect to and are wholely set, thereby guaranteed the accurately actual temperature of sensing evaporation tube of temperature-sensitive pipe, and then control refrigeration system, thereby the pipe that can avoid evaporating is cold and icing because of crossing, and improves refrigerating efficiency.In addition, the principle that the utility model utilizes chilled water density to sink greater than normal-temperature water, top at closed cold water tank is provided with the outlet pipe of drawing from the cold water tank bottom, by hydraulic pressure the chilled water of cold water tank bottom is discharged from outlet pipe, thereby the normal-temperature water that the chilled water that has guaranteed discharge is not introduced by water inlet pipe can influence and heats up, the shelves water plate of water inlet pipe below has slowed down the speed that normal-temperature water enters the cold water tank bottom, the heat exchange that also can slow down normal-temperature water and chilled water.So, water dispenser refrigerating efficiency height of the present utility model, good heat insulating, the temperature precise control, significantly energy-conservation.
Description of drawings
Fig. 1 is the section plan of an embodiment of the closed cold water tank of the utility model;
Fig. 2 is the three-dimensional cutaway view of an embodiment of the closed cold water tank of the utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Be the structural representation of the employed cold water tank of water dispenser as depicted in figs. 1 and 2.Cold water tank illustrated in figures 1 and 25 adopts closed overall structure, can be formed by connecting by as shown in the figure housing and not shown front shroud.Perhaps, this cold water tank 5 also can seal by the cover plate on any one other face.Can realize being tightly connected by welding or existing variety of way such as gluing before housing and the cover plate.
As shown in the figure, the top in the cold water tank 5 is provided with a grade water plate 4, and shelves water plate 4 can adopt existing various design, is installed in the slot on cold water tank 5 inwalls.Evaporation tube 1 and temperature-sensitive pipe 2 adopt built-in, are arranged on grade below of water plate 4.As depicted in figs. 1 and 2, evaporation tube 1 can be that diameter is the three circle helix tube type evaporation tubes that the 304 stainless steel coilings of 6mm form.In order accurately to record the temperature of evaporation tube, the pipe that avoids evaporating is cold and icing because of crossing, and temperature-sensitive pipe 2 is arranged to the screwed pipe shape temperature-sensitive pipe that is complementary with evaporation tube 1, is close to the lower end of evaporation tube 1.Perhaps, temperature-sensitive pipe 2 also can be close to the upper end of evaporation tube 1, perhaps inserts between two bung flanges of evaporation tube 1, is close to the screwed pipe of evaporation tube 1.Be provided with in the temperature-sensitive pipe 2 and be used for the temperature controller of sensing temperature with the work of control refrigeration system.Evaporation tube 1 and temperature-sensitive pipe 2 all are fastened on the sidewall of cold water tank 5 by sealing ring 6 and nut 8.Sealing ring 6 can be a T type silica gel circle, and evaporation tube 1 and cold water tank 5 are separated, and direct contact the between the screw thread of having avoided stainless steel tube and the plastic cement hole of cold water tank 5 reduced and damaged.The whole periphery of cold water tank 5 is enclosed with one deck heat-insulation layer 7.Be provided with for the two opening that is connected with external structure corresponding to the position that evaporation tube 1 and temperature-sensitive pipe 2 are installed on the heat-insulation layer 7.Heat-insulation layer 7 can be made by foam or expanded material.Among another embodiment of the present utility model, evaporation tube 1 and temperature-sensitive pipe 2 can be fastened on the bottom of cold water tank 5 by sealing ring 6 and nut 8.
As depicted in figs. 1 and 2, water inlet pipe 9 and outlet pipe 3 all are arranged on the top of cold water tank 5.Water inlet pipe 9 is used for normal-temperature water is introduced in the cold water tank 5, the delivery port of water inlet pipe 9 is facing to shelves water plate 4, making normal-temperature water enter the back is cushioned by shelves water plate 4 earlier, enter the bottom of cold water tank 5 then from the slit between the tank skin of shelves water plate 4 and cold water tank 5, so just, can alleviate the normal-temperature water flow velocity greatly, slow down normal-temperature water and enter the speed that chilled water temperature is raise.Outlet pipe 3 passes a grade water plate 4, extends to the bottom of cold water tank 5 always, is used for the chilled water of cold water tank 5 bottoms is drawn from the cold water tank top.Because chilled water density is greater than normal-temperature water, chilled water always sinks to the cold water tank bottom, so, under the hydraulic pressure effect, the introducing of normal-temperature water forces the chilled water of bottom to enter and extends in the outlet pipe 3 of cold water tank 5 bottoms, thereby the temperature that has guaranteed the chilled water of discharge is not influenced by normal-temperature water.The bottom of cold water tank 5 also is provided with drainpipe 10, when water dispenser normally uses, and drainpipe 10 sealings.Only when cold water tank 5 is cleaned, just can open, to discharge the water in the cold water tank 5.
The above closed cold water tank of introducing of the utility model is assembled into integrative-structure, thereby can be used as that parts are produced individually or the strange land produces good manufacturability.Closed cold water tank of the present utility model is packed into behind the water dispenser, and two ends of evaporation tube 1 link to each other with refrigeration system, and temperature controller inserts in the temperature-sensitive pipe 2.During the compressor refrigeration system operation, cryogenic media in the evaporation tube 1 directly passes to cold water in the cold water tank 5 by evaporation tube 1, reduce the temperature of water in the cold water tank, and control opening of whole refrigeration system and stop by linking temperature controller in the all-in-one-piece temperature-sensitive pipe 2 with evaporation tube 1, make cold water remain on the temperature requirement scope of setting.Because water pot need not to carry out the cold conduction, can adopt plastic material to make, and has reduced cost when strengthening heat insulation effect.
