[0002] As a household appliance that can dry clothes quickly, heat pump dryers can dry clothes quickly and energy-efficiently, especially in humid weather, reducing the space used for drying clothes and improving people's quality of life.

[0003] Most existing heat pump dryers use air cooling to dissipate heat from the compressor, that is, a cooling fan is installed at the front end of the compressor. The operation of the cooling fan will reduce the exhaust temperature of the compressor and the refrigerant pressure on the high-pressure side of the refrigerant cycle, which is beneficial to the safe operation of the heat pump system. It will also effectively improve the condensation problem in the dryer under low temperature conditions. However, in seasons with high ambient temperatures or in stacked applications of dryers, the compressor is prone to insufficient heat dissipation, causing thermal protection and failing to work properly. When using air cooling, an air inlet needs to be opened in the lower right corner of the front panel of the dryer, which damages the integrity of the front panel and affects the appearance. The noise generated when the cooling fan is in operation is relatively large, which affects the user experience. Dust accumulation inside the dryer is relatively serious, the cleaning cost is high, and the service life is short. Utility Model Content

[0025] like Figure 1 As shown, this embodiment provides a heat pump system, which includes a compressor 1 and a water cooling component, the water cooling component is used to cool the compressor 1, the water cooling component includes a water cooling pipeline, at least part of the water cooling pipeline is arranged on the shell of the compressor 1, the water cooling pipeline is made of a heat conductive material, cooling water flows in the water cooling pipeline, and the cooling water is used to exchange heat with the shell of the compressor 1. The heat conductive material can be copper, which has good thermal conductivity, is easy to obtain, and has low cost.

[0026] The water cooling component uses water cooling to cool down the compressor 1, with low operating noise, which improves the user's experience, reduces the accumulation of dust inside the dryer, reduces the cleaning cost of the dryer, extends the service life of the dryer, and alleviates the user's blind spot hygiene anxiety. Compared with the existing air cooling method, the water cooling method has higher cooling efficiency and richer application scenarios, which solves the problem of thermal protection caused by insufficient heat dissipation of the compressor 1. The compressor 1 adopts a water cooling method, and there is no need to open the front panel of the dryer, which retains the integrity of the front panel and makes the dryer more beautiful. At least a part of the water cooling pipeline of the water cooling component is arranged on the outer shell of the compressor 1, and the outer shell of the compressor 1 is directly contact-cooled, which improves the cooling efficiency. Since the water cooling pipeline is made of heat-conducting material, cooling water flows in the water cooling pipeline, and heat is exchanged between the cooling water and the outer shell of the compressor 1, the heat exchange efficiency is high and the cooling speed is fast.

[0027] In some embodiments, the water cooling pipeline includes an inlet pipeline 2, a cooling pipeline 3 and a return pipeline 4. The inlet pipeline 2 is connected to the return pipeline 4 through the cooling pipeline 3, and the cooling pipeline 3 is arranged on the outer shell of the compressor 1. The cooling water enters the cooling pipeline 3 through the inlet pipeline 2, completes heat exchange with the outer shell of the compressor 1 in the cooling pipeline 3, and then enters the return pipeline 4. In order to ensure the water temperature of the cooling water, an insulation layer can be arranged on the outer peripheral side of the inlet pipeline 2. The cooling pipeline 3 can be close to the outer shell of the compressor 1 to increase the contact area between the cooling pipeline 3 and the outer shell of the compressor 1, thereby improving the cooling efficiency of the compressor 1.

[0028] In order to improve the cooling efficiency of the cooling pipeline 3, the cooling pipeline 3 is optionally wound in a spiral shape on the outer shell of the compressor 1. The outer shell of the compressor 1 is usually cylindrical, and the cooling pipeline 3 is wound in a spiral manner on the outer shell of the compressor 1, which can maximize the contact area between the cooling pipeline 3 and the outer shell of the compressor 1 and achieve sufficient heat exchange. The shape of the cooling pipeline 3 is adapted to the shape of the outer shell of the compressor 1, which speeds up the cooling speed of the compressor 1.

[0029] In some embodiments, the water cooling assembly further includes a valve disposed on the water inlet pipe 2, and the valve is used to adjust the cooling water flow of the cooling pipe 3. The valve can be manually adjusted by a mechanical valve or automatically controlled by an electromagnetic valve to meet the needs of different application scenarios. The cooling water flow can be adjusted according to the temperature of the compressor 1 to achieve precise temperature control and save costs.

[0030] Optionally, the water cooling assembly further comprises a water storage container 5, the water outlet of the water storage container 5 is connected to the water inlet pipeline 2, and the water return port of the water storage container 5 is connected to the water return pipeline 4. The water storage container 5 can adopt a water box-shaped structure, which is easy to manufacture, convenient to install, has a large capacity, and occupies a moderate space. A sealing ring is provided between the water outlet of the water storage container 5 and the water inlet pipeline 2, and between the water return port of the water storage container 5 and the water return pipeline 4 to prevent cooling water from leaking at the joints.

[0031] In some embodiments, the water cooling assembly also includes a water pump, which is used to pressurize the cooling water in the water inlet pipe 2. The inlet of the water pump is connected to the water outlet of the water storage container 5, and the outlet of the water pump is connected to the water inlet pipe 2. By adjusting the speed of the water pump, precise temperature control can be achieved. The water pump transfers the mechanical energy of the motor to the cooling water, thereby increasing the energy of the cooling water. The water pump can be a volumetric water pump or a vane pump. A volumetric pump transfers energy by using the change in the volume of its working chamber. A vane pump transfers energy by using the interaction between rotating blades and water, and there are centrifugal pumps, axial flow pumps, and mixed flow pumps.

[0032] Optionally, the heat pump system further includes an evaporator 6, at least part of the evaporation tube of the evaporator 6 is located in the water storage container 5. The temperature of the cooling water entering the water storage container 5 through the return water pipeline 4 is relatively high, and the cooling of the cooling water in the water storage container 5 can be achieved through the evaporation tube of the evaporator 6. The refrigerant in the evaporation tube exchanges heat with the cooling water in the water storage container 5 to achieve cooling and lowering of the cooling water in the water storage container 5, and then the cooled cooling water is transported to the water inlet pipeline 2 under the pressure of the water pump to provide cooling water with a lower temperature for the cooling pipeline 3.

[0033] In some embodiments, the heat pump system further includes a condenser 7 and a throttle valve 8. The evaporator 6 is arranged upstream of the compressor 1, the condenser 7 is arranged downstream of the compressor 1, the throttle valve 8 is arranged downstream of the condenser 7 and upstream of the evaporator 6. The evaporator 6, the compressor 1, the condenser 7 and the throttle valve 8 constitute a heat pump circulation loop. The refrigerant is compressed into a high-temperature and high-pressure gas by the compressor 1, and then condensed into a liquid by the condenser 7, emitting a large amount of heat. The hot air is blown out by the fan to dry the clothes. The condenser 7 cools down. At this time, the refrigerant becomes a medium-temperature and medium-pressure gas-liquid mixture. Then, it is reduced in pressure and cooled by the throttle valve 8 to become a low-temperature and low-pressure gas-liquid mixture. Then, it is converted with external heat by the evaporator 6, absorbs a large amount of heat and vaporizes, and becomes a low-temperature and low-pressure gas again. The water is separated and discharged, and the low-temperature and low-pressure gas starts from the compressor 1 again, and the cycle is repeated. In the drying process, the heat is transferred to the drying room through the heat pump circulation system, and the heat is recycled to heat the air so that the clothes reach a dry state.

[0034] Optionally, the compressor 1 is provided with an exhaust port, and the exhaust port is provided with a temperature sensor, and the temperature sensor is used to detect the temperature of the compressor 1. The system sets an optimal operating temperature range for the compressor 1. When the temperature of the compressor 1 exceeds the optimal operating temperature range, the water pump starts to work, and the cooling water starts to circulate along the set path, exchanges heat with the compressor 1 when flowing through the surface of the compressor 1, and takes away the heat of the compressor 1.

[0035] The present embodiment also provides a clothes dryer, comprising a housing and the above-mentioned heat pump system, wherein the heat pump system is arranged in the housing. The water cooling component uses water cooling to cool down the compressor 1, with low operating noise, which improves the user's experience, reduces the accumulation of dust inside the clothes dryer, reduces the cleaning cost of the clothes dryer, prolongs the service life of the clothes dryer, and alleviates the user's blind spot hygiene anxiety. Compared with the existing air cooling method, the water cooling method has higher cooling efficiency and richer application scenarios, which solves the problem of thermal protection caused by insufficient heat dissipation of the compressor 1. The compressor 1 uses water cooling, and there is no need to open the front plate of the clothes dryer, which retains the integrity of the front plate and makes the clothes dryer more beautiful. At least a part of the water cooling pipeline of the water cooling component is arranged on the outer shell of the compressor 1, and the outer shell of the compressor 1 is directly contact-cooled, thereby improving the cooling efficiency. Since the water cooling pipeline is made of heat-conducting material, cooling water flows in the water cooling pipeline, and heat is exchanged between the cooling water and the outer shell of the compressor 1, the heat exchange efficiency is high and the cooling speed is fast.
