[0080] Meanwhile, the small submersible pump is connected with the second joint through the submersible pump pipe body, water is made to enter the main submersible pump (in the water chiller) through the connecting piece and the hose, conditions are provided for normal starting of the main submersible pump, the exhaust operation that may occur in use of the water chiller by the customer is saved, and the customer is facilitated to use. Compared with the above scheme, the exhaust scheme has the characteristics of silence. Meanwhile, after the vacuum pump in the water chiller is damaged, it is difficult to repair, and the water chiller needs to be disassembled for repair. If the submersible pump in the water inlet and outlet connecting body is damaged, only a new water inlet and outlet connecting body needs to be configured for the water chiller, even if the vacuum pump in the water chiller is not repaired, the submersible pump in the water inlet and outlet connecting body can ensure normal exhaust of the water chiller, and the maintenance cost is reduced.

[0081] On the basis of the above embodiment, another embodiment is shown in the drawing. Figure 11 The water chiller system provided by the utility model is applicable to various bathtubs without any modification, realizes supply of cold and hot water, is simple to operate, and is convenient to use.

[0082] The working principle of the utility model is as follows:

[0083] One end of the water inlet and outlet connector is inserted into the water storage device, the bathtub is opened, the vacuum pump in the starting emptying system is started, the gas in the cold water pipeline before the main water pump is discharged to the rear end of the one-way valve 13 through the vacuum pump, the cold water pipeline before the main water pump forms a negative pressure state, the water in the bathtub can flow into the main water pump inlet through the cold water machine water inlet connected with the water inlet and outlet connector under the action of negative pressure, then the main water pump is started, the vacuum pump is stopped, the water flows through the evaporator in the refrigeration cycle circuit system, the evaporator evaporates the water into superheated steam, the superheated steam passes through the compressor, the compressor compresses the superheated steam into high-temperature and high-pressure gas, and discharges to the condenser, the condenser condenses the high-temperature and high-pressure gas into high-pressure liquid, and the high-pressure liquid is discharged through the cold water machine water outlet communicated with the water inlet and outlet connector, and then enters the bathtub through the water inlet and outlet connector, so that the temperature of the bathtub is lowered, and the hot water in the bathtub enters the cold water circulation system through the water inlet and outlet connector, so that the cold and hot exchange is repeated, and the refrigeration purpose is achieved.

[0084] The utility model provides a high applicability, convenient to use's cold water machine system provides a simple connection, installation mode for the user, has improved the experience feeling of customer to product. The present application overcomes the installation operation, installation applicability problem of the prior art of cold water machine technology can not provide effectively, and avoids the operation problem of the customer to the cold water machine exhaust, greatly simplifies the installation process of cold water machine, makes the user can plug and play, and the operation is simple and convenient, and the market competitiveness is improved greatly.

[0085] The specific embodiments of the utility model are described above. It should be understood that the utility model is not limited to the above specific embodiments, and those skilled in the art can make various changes or modifications within the scope of claims, which does not affect the essential content of the utility model. In the case of no conflict, the embodiments of the present application and the features in the embodiments can be combined with each other arbitrarily.
