The third valve 254 is used to control the communication between the first fluid flow path f and the second fluid flow path m. The first fluid flow path f is connected to a water collection tank 29.

[0088] In some embodiments, a temperature sensor (not shown) is provided on the water collection tank 29 to monitor whether the temperature of the fluid (such as water) in the water collection tank 29 meets the cleaning temperature. When the cleaning temperature is met, the fifth valve port 252 is closed, and the fourth valve port 251 and the sixth valve port 253 are connected, that is, the second fluid flow path m is connected to the third fluid flow path n, so that the fluid in the water collection tank is sprayed into the washing chamber 300 through the spray section 30. When the cleaning temperature is not met, the fifth valve port 252 is closed, and the fourth valve port 251 and the sixth valve port 253 are connected, that is, the second fluid flow path m is connected to the first fluid flow path f, so that the fluid in the first fluid flow path f flows into the sleeve 131, exchanges heat with the heat exchange tube 132 to raise the temperature, and then the first fluid flow path f is connected to the third fluid flow path n, and then sprayed into the washing chamber 302 through the spray section 30.

[0089] The dishwasher heat pump system in this application includes a washing mode and a drying mode; in some embodiments, refer to Figure 16As shown, the cleaning mode is divided into a heat exchange fluid circulation path and a coolant circulation path. The heat exchange fluid circulation path is as follows: When the first fan 18 operates, the high-temperature, high-pressure gas heat exchange fluid discharged from the compressor 11 flows through the first valve 12 into the heat exchange tube 132 of the second condenser 13 for condensation, releasing a large amount of heat to heat the fluid in the sleeve 131. After passing through the first one-way valve 14 and the dryer filter 15, it enters the first throttling valve 16 for throttling. After throttling, it becomes a gas-liquid two-phase heat exchange fluid, and then enters the first air heat exchanger. The device 17 has a first fan 18 installed near the first air heat exchanger 17. The first fan 18 drives the air from the surrounding environment to enter the first air heat exchanger 17 through the compressor 11, and then discharges it to the outside environment through the first fan 18, forming a first flow ventilation duct 500. On the one hand, it can dissipate heat from the compressor 11 and improve the service life of the compressor 11. On the other hand, the first air heat exchanger 17 can use the waste heat generated by the compressor 11 for heat exchange. After absorbing heat in the first air heat exchanger 17, the heat exchange fluid becomes a low-temperature, low-pressure gas and returns to the compressor 11.

[0090] In some embodiments, during the cleaning mode, the fluid circulation path is as follows: the first water pump 24 is started, the coolant stored in the water collection tank 29 enters the second valve 25, the sixth valve port 253 is closed, the fourth valve port 251 is connected to the second valve port 252, the fluid enters the sleeve 131 for heating, then flows through the third fluid flow path n, and is sprayed into the washing chamber 302 through the spray section 30. The sprayed fluid flows back to the water collection tank 29, realizing a fluid flow cycle; when the fluid in the water collection tank 29 meets the cleaning temperature, the fourth valve port 251 is connected to the sixth valve port 253, the fifth valve port 252 is closed, the fluid in the water collection tank 29 flows through the second fluid flow path m, then through the second valve 25 and through the third fluid flow path n, enters the spray section 30 and is sprayed into the washing chamber 300. The sprayed fluid flows back to the water collection tank 29, realizing a fluid flow cycle.

[0091] In some embodiments, under the cleaning mode, the fluid circulation path is as follows: the first water pump 24 starts, the coolant stored in the water collection tank 29 enters the second fluid flow path m, the third valve 254 is opened, and the second fluid flow path m is connected to the first fluid flow path f and the third fluid flow path n respectively. The fluid in the first fluid flow path f enters the sleeve 131 for heating, and then returns to the water collection tank 29; the fluid in the third fluid flow path n directly enters the spray section 30 and is sprayed into the washing chamber 302. The sprayed fluid flows back to the water collection tank 29, and the fluid that passed through the first fluid flow path f and the sprayed fluid are collected in the water collection tank. The mixture in tank 29 raises the temperature of the fluid in the collection tank 29, causing continuous circulation until the washing temperature required for tableware such as bowls and chopsticks is reached. When the washing temperature is reached, the third valve 254 closes, and the fluid in the collection tank 29 enters the third fluid flow path n through the second fluid flow path m. The fluid in the third fluid flow path n directly enters the spray section 30 and is sprayed into the washing chamber 300. The sprayed fluid flows back to the collection tank 29, realizing a fluid flow cycle. That is, the first fluid flow path f and the third fluid flow path n are connected in parallel, which can reduce the operating resistance of the first water pump 24 and achieve energy saving and high efficiency.

[0092] In some embodiments, under drying mode, the circulation path of the heat exchange fluid is as follows: The second fan 22 operates, and the high-temperature, high-pressure gaseous heat exchange fluid discharged from the compressor 11 passes through the first valve 12, with the first valve port 121 connected to the second valve port 122. The heat exchange fluid then passes through the first condenser 21, where it releases latent heat and becomes a high-temperature, high-pressure liquid heat exchange fluid. This liquid then passes through the second one-way valve 124 and the drying filter 15, and is further throttled by the second throttling valve 20, becoming a two-phase gas-liquid heat exchange fluid that enters the second evaporator 23. After absorbing heat, it becomes a low-temperature, low-pressure gas and returns to the compressor. 11; The flow path of the gas-liquid dual-state coolant in the second flow ventilation duct 600 is as follows: the high-temperature and high-humidity gaseous coolant in the washing chamber 300 is liquefied and condensed into liquid on its surface through the second evaporator 23 and discharged. Then it passes through the first condenser 21, absorbs the heat released by the first condenser 21, and becomes a high-temperature and low-humidity gas that enters the washing chamber 300. The water droplets on the surface of the tableware in the washing chamber 21 absorb heat and evaporate. The water droplets formed on the surface of the second evaporator 23 are discharged from the dishwasher heat pump device through the water collection tank and other equipment. In this cycle, the humidity in the washing chamber 300 will decrease until the drying requirements are met.

[0093] In this application, a first air heat exchanger 17 and a second condenser 13 are used in the cleaning mode, and a first condenser 21 and a second evaporator 23 are used in the drying mode. That is, different evaporators and condensers are used in the cleaning mode and the drying mode respectively. Evaporators and condensers with different heat exchange areas can be provided according to the heat exchange needs of different modes to achieve energy saving and high efficiency. At the same time, it can also enable the dishwasher heat pump system to operate better.

[0094] It should be noted that the refrigerants mentioned in this application include, but are not limited to, R22, R32, R290, R410A, etc.; the washing liquid includes, but is not limited to, water, cleaning agents, and liquids mixed with water and cleaning agents.
