Abstract

The utility model relates to a cold drink machine water tank which comprises a tank body, and a water inlet tube, a water outlet tube and a dirt drainage tube are arranged on the tank body. The utility model is characterized in that the tank body is of a detachable and fully sealed structure; the inner part of the tank body is provided with a water level control valve; an inflation tube is arranged on the tank body, and the air outlet point of the inflation tube is higher than the height of the cold drinking water in the tank body; the wall of the tank body is provided with a rectangular multi-tube heat exchanger. Because the utility model can automatically control the water level in the tank body, the water tank can not sustain pressure and the external appearance is free of limitation. The water tank adopts seal structure, so that air can be prevented from infiltrating and the quality of the water can not be polluted. Non-pressurized protective nitrogen is filled into the tank by utilizing the inflation tube, and oxygen can be isolated so as to prevent microbe form growing. The inflation tube also has the function of vacuum pumping so as to prevent air pollution and strengthen heat transferring effect.

Description

The cold drink machine water pot

One, technical field

The utility model relates to a kind of cold drink machine water pot.

Two, background technology

At present, the cold and hot water drinking machine in market has two classes: a class is to adopt bottled water, but the user needs normal water-exchanging bucket, and is very inconvenient.Another kind of is directly to connect tap water, utilize filtering installation with tap water filter to drinking, but because the water pot pressure-bearing belongs to pressure container.The pressure container shape is necessary for: middle for cylindrical, two is a semisphere.The problem of this type of pressure-bearing water pot existence is at present: 1, water pot belongs to pressure container, and manufacture process requirement is higher, is difficult to maximize produce.2, the heat exchanger that carries out cold exchange with water pot adopts circular copper pipe to be wrapped in the water pot outer wall, and the problem of bringing again thus is, A, heat exchange copper tube belong to line with the water pot outer wall and contact, and its contact is bad, so the heat exchange weak effect.The winding process quality of B, copper pipe (winding tightness) is difficult to control, and the product design fluctuation is big, also causes the refrigeration system fluctuation big simultaneously, and refrigeration system reliability descends.

Three, the content of utility model

The purpose of this utility model provides a kind of water pot and does not bear pressure, and profile is unrestricted, the cold drink machine water pot that tank skin can well contact with heat exchanger.

In order to achieve the above object, the utility model is achieved in that and comprises tank body, be provided with coolant inlet pipe, coolant outlet pipe and blow-off pipe on tank body; It is characterized in that: tank body is detachable all-sealed structure; In tank body, be provided with altitude valve; Be provided with appendix on tank body, the air extractor duct place of appendix is higher than jar height of interior Cold Drinking Water; On tank wall, be provided with the rectangle multi-pipe heat exchanger.

The utility model further is improved to, and altitude valve comprises spool that is installed in coolant inlet pipe water inlet place and the ball float of controlling spool.Tank body is made up of loam cake and housing, is provided with seal ring between loam cake and housing; On cover one toward the zone of lower recess, the part of its depressed area contacts with Cold Drinking Water, the rectangle multi-pipe heat exchanger is located on the depressed area; Above-mentioned coolant inlet pipe, coolant outlet pipe, blow-off pipe and appendix are located on the housing.

The utility model further is improved to again, is provided with heat-conducting medium on the surface of depressed area.

The utility model compared with prior art has following advantage:

1, owing to the water level in its automatic guidance tank body, water pot does not bear pressure, and profile is unrestricted;

2, water pot adopts hermetically-sealed construction, thereby prevents that air from infiltrating, and do not pollute water quality;

3, utilize appendix to charge into the protectiveness nitrogen of normal pressure in jar, starvation prevents growth of microorganism, and appendix also has the effect-anti-air-pollution that vacuumizes.

4, enhance heat transfer effect.

Four, description of drawings

Fig. 1 is a structural representation of the present utility model.

Five, the specific embodiment

Below in conjunction with drawings and Examples the utility model is done further detailed description:

As shown in Figure 1, comprise tank body 1, it is made up of loam cake 12 and housing 11, is provided with seal ring 10 between loam cake and housing, thereby constitutes the tank body of detachable all-sealed structure.On housing 11, be provided with coolant inlet pipe 5, coolant outlet pipe 3, blow-off pipe 4 and appendix 2.Loam cake 12 has a zone toward lower recess, and the part of depressed area 13 contacts with Cold Drinking Water, so that better carry out heat conduction, is provided with heat-conducting medium 9 in its surface, and rectangle multi-pipe heat exchanger 8 is located on the depressed area.In housing 11, be positioned at the ball float 7 that coolant inlet pipe water inlet place is provided with spool 6 and control spool; The air extractor duct place of appendix 2 is higher than jar height of interior Cold Drinking Water.

During use, water flows into from coolant inlet pipe 5, and when water level reach a certain height, ball float 7 was closed spool 6; Appendix 2 can play pressure release, also can charge into nitrogen by it, with starvation; After using a period of time, can pass through blow-off pipe 4 blowdowns.
