[0008] Preferably, the compressor air inlet pipe of the refrigeration structure includes thermal insulation cotton.

[0009] Preferably, the refrigeration structure further comprises a pressure gauge arranged on the compressor, and the pressure gauge is used to monitor the pressure of the compressor.

[0010] Preferably, the heating tube is a U-shaped electric heating tube, and the heating tube is inserted into the side wall of the water collecting tank, and the interface between the heating tube and the water collecting tank is sealed with a waterproof tape.

[0011] Preferably, the water supply device also includes a temperature control device, which includes an air switch, an AC contactor, a cooling thermostat, a heating thermostat, and a temperature sensing probe arranged in a water collecting tank; the air switch is electrically connected to the AC contactor; the AC contactor is electrically connected to the cooling thermostat and the heating thermostat respectively; the AC contactor is electrically connected to the compressor, the fan, and the heating pipe respectively; the cooling thermostat and the heating thermostat are both electrically connected to the temperature sensing probe.

[0016] Due to the adoption of the above technical solution, the beneficial effects of the utility model are as follows:

[0017] (1) In the utility model, a refrigeration structure composed of a compressor, a condenser, and an evaporator arranged inside a water collecting tank is used to cool the water in the water tank. Since the evaporator is arranged inside the water collecting tank, it is convenient to wrap thermal insulation cotton on the outer surface of the water collecting tank, which can ensure both the refrigeration effect and the thermal insulation effect, effectively overcoming the problem in the prior art that it is not convenient to use thermal insulation cotton to wrap the water tank body, resulting in poor thermal insulation performance of the water tank body.

[0018] (2) In the present invention, a refrigeration structure composed of a compressor, a condenser, and an evaporator arranged inside a water collecting tank is used. The fine aperture inside the capillary tube is used to limit the flow of the refrigerant, thereby controlling the pressure difference between different areas of the refrigerant. When refrigeration is performed, the refrigerant will be compressed into a high-pressure gas under the action of the compressor, and then the heat will be released through the condenser tube to cool the refrigerant into a high-pressure liquid. After the high-pressure liquid refrigerant enters the capillary tube, the flow speed and pressure will be reduced due to the fine aperture inside the capillary tube. After the refrigerant flows through the capillary tube, the pressure drop causes its flow rate and pressure to be significantly reduced, and it becomes a low-pressure liquid and enters the evaporator. At this time, the refrigerant will further evaporate, absorb the heat of the water body inside the water collecting tank, and take it away. Under the action of the compressor, it will be compressed into a high-pressure gas and enter the condenser tube, and the above process will be repeated. In the present invention, by adopting the above refrigeration structure, the refrigeration effect is good, which is conducive to rapid refrigeration.

[0019] (3) In the present invention, by arranging a drying filter before the capillary tube, the purpose of filtering impurities and moisture can be achieved.

[0020] (4) In the present invention, by utilizing an air switch, an AC contactor, a cooling thermostat, a heating thermostat, and a temperature control device composed of a temperature sensing probe arranged in a water collecting tank, integrated cold and hot constant temperature control of water bodies is achieved, which can be used for indoor simulation experiments of water supply and drainage in engineering projects.

[0030] Combination Figures 1 to 4As shown, a water supply device with integrated cold and hot constant temperature control for a water collecting body comprises a water collecting box 42 and a water pipe 41, wherein the water inlet end of the water pipe 41 is connected to a water source, and the water outlet end of the water pipe 41 extends into the interior of the water collecting box 42, and also comprises a refrigeration structure and a heating structure; the heating structure is a heating pipe 31 arranged inside the water collecting box 42; the refrigeration structure comprises a compressor 25, a condenser 23, and an evaporator 27 arranged inside the water collecting box 42; the outlet of the evaporator 27 is connected to the inlet of the compressor 25 through a compressor air inlet pipe 251, and the inlet of the condenser 23 is connected to the outlet of the compressor 25 through a compressor exhaust pipe 252; the outlet of the condenser 23 is connected to the inlet of the evaporator 27 after being connected in series with a drying filter 21 and a capillary tube 22 in sequence; the condenser 23 is filled with refrigerant; a fan 24 for assisting condensation is arranged on one side of the condenser 23; a drain outlet 44 is arranged on the water collecting box 42; and thermal insulation cotton is wrapped on the outer surface of the water collecting box 42.

[0031] Combination Figure 1 , Figure 3 As shown, a variable frequency water pump 43 is provided at the water outlet of the water pipe 41 , and the water inlet of the water pipe 41 is connected to a water source which may be a tap water pipe, or a pool, etc. The variable frequency water pump 43 is used to pump water from the water source into the water collecting tank 42 .

[0032] Combination Figure 3 The compressor air inlet pipe 251 of the refrigeration structure includes heat insulation cotton. By providing the heat insulation cotton, the condensing agent in the compressor air inlet pipe 251 is prevented from exchanging heat with the air to liquefy, thereby affecting the normal operation of the compressor 25.

[0033] Combination Figure 1 and Figure 3 , Figure 4 As shown, the refrigeration structure further includes a pressure gauge 26 disposed on the compressor 25 . The pressure gauge 26 is used to monitor the pressure of the compressor 25 . By providing the pressure gauge 26 , it is convenient to observe the pressure inside the compressor 25 .

[0034] Combination Figure 3 As shown, the heating pipe 31 is a U-shaped electric heating pipe, and the heating pipe 31 is inserted on the side wall of the water collecting box 42, and the interface between the heating pipe 31 and the water collecting box 42 is sealed with a waterproof tape. The U-shaped electric heating pipe structure is conducive to simplifying the device structure.

[0035] Combination Figure 3As shown, the water supply device also includes a temperature control device, which includes an air switch 111, an AC contactor 112, a cooling thermostat 113a, a heating thermostat 113b, and a temperature sensing probe 12 arranged in the water collecting tank 42; the air switch 111 is electrically connected to the AC contactor 112; the AC contactor 112 is electrically connected to the cooling thermostat 113a and the heating thermostat 113b respectively; the AC contactor 112 is electrically connected to the compressor 25, the fan 24, and the heating tube 31 respectively; the cooling thermostat 113a and the heating thermostat 113b are both electrically connected to the temperature sensing probe 12. Specifically, there are two temperature probes 12, namely, a first temperature probe 12a and a second temperature probe 12b; the first temperature probe 12a is electrically connected to the cooling thermostat 113a; the second temperature probe 12b is electrically connected to the heating thermostat 113b; the air switch 111, the AC contactor 112, the cooling thermostat 113a, and the heating thermostat 113b are all integrated and installed on the temperature control box 11. The air switch 111 is used to control the power on or off of the entire device. The specific control principle is as follows:

[0036] The first temperature sensing probe 12a transmits the resistance signal to the refrigeration thermostat 113a, which converts the resistance signal into a standard voltage signal and transmits it to the AC contactor 112. The AC contactor 112 connects or disconnects the contacts, thereby changing the output of the cold source.

[0037] The second temperature sensing probe 12b transmits the resistance signal to the heating thermostat 113b, which converts the resistance signal into a standard voltage signal and transmits it to the AC contactor 112. The AC contactor 112 connects or disconnects the contacts, thereby changing the output of the heat source.

[0038] Combination Figure 4 As shown, the refrigeration principle includes compression process, condensation process, expansion process, and evaporation process, and the four processes are cyclically repeated. The small aperture inside the capillary 22 is used to limit the flow of the refrigerant, thereby controlling the pressure difference between different areas of the refrigerant. When refrigerating, the high-temperature and low-pressure refrigerant gas of the evaporator 27 will be compressed into high-pressure gas under the action of the compressor 25, and enter the condenser 23 through the compressor exhaust pipe 252 to release heat and cool the refrigerant into a low-temperature and high-pressure liquid. The low-temperature and high-pressure liquid refrigerant is filtered of impurities and moisture by the drying filter 21. After the low-temperature and high-pressure liquid refrigerant enters the capillary 22, due to the small aperture inside the capillary 22, the flow speed and pressure will be reduced. After the refrigerant flows through the capillary 22, the pressure drop makes its flow rate and pressure significantly reduced, and it becomes a low-pressure liquid and enters the evaporator 27. At this time, the refrigerant will further evaporate, absorb the heat of the water body inside the water collecting tank 42, and take it away. Under the action of the compressor 25, it will be compressed into a high-pressure gas and enter the condenser 23, and repeat the above process.

[0039] By adopting the above-mentioned temperature control device, when in use, there are two modes: one is cooling mode and the other is heating mode. The first temperature sensing probe 12a is electrically connected to the cooling thermostat 113a. When the water temperature detected by the first temperature sensing probe 12a is higher than the set value, the cooling thermostat 113a controls the AC contactor 112 to start the compressor 25 and the fan 24, and the heating tube 31 does not work at this time. The second temperature sensing probe 12b is electrically connected to the heating thermostat 113b. When the water temperature detected by the second temperature sensing probe 12b is lower than the set value, the heating thermostat 113b controls the AC contactor 112 to start the heating tube 31 for heating, and the compressor 25 and the fan 24 do not work at this time.

[0040] In this embodiment, the outlet end of the capillary tube 22 is inserted into the water collecting tank 42 and connected to the inlet of the evaporator 27; a sealant is provided between the outer peripheral surface of the outlet end of the capillary tube 22 and the plug hole of the water collecting tank 42. Furthermore, the inlet end of the compressor air inlet pipe 251 is inserted into the water collecting tank 42 and connected to the outlet of the evaporator 27; a sealant is provided between the outer peripheral surface of the inlet end of the compressor air inlet pipe 251 and the plug hole of the water collecting tank 42.

[0041] Combination Figure 1 As shown, in this embodiment, the evaporator 27 is installed on the inner wall of the water collecting tank 42 in a gradually descending and winding manner from the inlet end to the outlet end; the condenser tube 23 is a spiral tube structure.

[0042] Combination Figure 1 As shown, the water collecting tank 42, the temperature control box 11, the fan 24, the condenser 23, the drying filter 21, and the capillary tube 22 are all installed on the bracket 51 to form an integral structure.
