[0002] As people's living standards improve, dishwashers have entered more and more households to automatically wash dishes and cooking utensils such as bowls, chopsticks, plates, and dishes. In order to improve the decontamination ability, the dishwasher needs to heat the detergent during operation. In traditional technology, electric heating tubes are usually used to heat the detergent, and after heating, they are sprayed out through the spray arm assembly to wash away the stains on the tableware. The heating principle of the electric heating tube is the thermal effect of electric current. It consumes more electrical power to heat the detergent in the dishwasher. In this case, dishwashers that use heat pump technology for heating have emerged, which can effectively reduce energy consumption.

[0028] like Figure 1 to Figure 2 As shown, this embodiment provides a heat pump system, which is used to heat washing water for use in a washing device. After the washing water is heated, it can be sprayed out through a spray arm assembly of the washing device to wash away stains on tableware. The heat pump system includes a compressor 1, a condenser 2, an evaporator 3, and a refrigerant pipeline that constitute a refrigerant cycle. The compressor 1 is used to compress the refrigerant, the condenser 2 and the evaporator 3 are used to exchange heat with the refrigerant, and the refrigerant pipeline is used to transport the refrigerant. The refrigerant pipeline is bent and coiled on the outer peripheral side of the compressor 1.

[0029] When the compressor 1 is working, the refrigerant expands by doing work in the compressor 1, and then enters the condenser 2 through the refrigerant pipeline. The refrigerant releases heat in the condenser 2 to heat the washing water. Then, the refrigerant enters the evaporator 3. After absorbing heat in the evaporator 3, the refrigerant finally returns to the compressor 1 through the refrigerant pipeline. The refrigerant pipeline is bent and coiled around the outer peripheral side of the compressor 1. The bending radius is determined according to the diameter of the pipeline itself, and the number of bends is determined by the outer diameter of the compressor 1. The refrigerant pipeline is as close to the compressor 1 as possible to achieve the best shock absorption effect. The design of the bent pipeline of the refrigerant pipeline coiled around the outer peripheral side of the compressor 1 plays a role in assisting the shock absorption of the compressor 1, reducing the vibration amplitude of the compressor 1 when it is working, extending the service life of the compressor 1, reducing the working noise of the washing equipment, enhancing the product competitiveness, and improving the user experience.

[0030] The bending direction of the bending structure is selected according to the internal space of the washing device. Optionally, the refrigerant pipeline is bent in the vertical direction; and / or the refrigerant pipeline is bent in the horizontal direction. In order to avoid the bending structure having a dead angle that affects the passage of the refrigerant, the bending structure can be designed to be relatively smooth, and the refrigerant pipeline is wavy.

[0031] Optionally, the refrigerant pipeline includes a condenser tube 4 and an evaporator tube 5, the compressor 1 is connected to the condenser 2 through the condenser tube 4, and the evaporator 3 is connected to the compressor 1 through the evaporator tube 5. When the compressor 1 is working, the refrigerant expands in the compressor 1 by doing work, and then enters the condenser 2 through the condenser tube 4, and the refrigerant releases heat in the condenser 2 to heat the washing water, and then the refrigerant enters the evaporator 3, and after absorbing heat in the evaporator 3, the refrigerant finally returns to the compressor 1 through the evaporator tube 5.

[0032] Since the evaporator 3 is installed on the side wall of the washing equipment and is not easy to bend, it will cause great inconvenience during the later installation and production. In order to facilitate the installation of the side evaporator 3 and the assembly and adjustment of the heat pump system, the evaporator 3 is optionally connected to the evaporation tube 5 through a connecting pipe 6, and the connecting pipe 6 includes a metal tube 61, a locking sleeve 62 and a rubber tube 63. The metal tube 61 is connected to the rubber tube 63 through the locking sleeve 62, the metal tube 61 is connected to the evaporator 3, and the rubber tube 63 is connected to the evaporation tube 5. The material selection of the rubber tube 63 is convenient for laying the evaporator 3 flat during transportation, and then erecting the evaporator 3 during installation. Optionally, the evaporator 3 is made of metal material. The locking sleeve 62 can be connected to the metal tube 61 by threaded connection, and the locking sleeve 62 can be connected to the rubber tube 63 by clamping. The evaporator 3 can be made of copper, which is easy to bend and forge, has excellent heat conduction efficiency, and good flexibility.

[0033] Optionally, the heat pump system further includes a throttling device 7, and the condenser 2 is connected to the evaporator 3 via the throttling device 7. The throttling device 7 can also keep the heat exchange between the refrigerant and the outside temperature low, reducing the heat loss of the refrigerant during transportation. The throttling device 7 can be a capillary tube. Since the throttling device 7 has excellent toughness, the evaporator 3 can be folded during the installation and subsequent maintenance of the washing equipment.

[0034] The condenser 2 is connected to the heating pump 8. The heating pump 8 is a device that utilizes low-temperature heat energy in the air, underground, surface or water body and converts it into high-temperature heat energy by increasing heat energy. Its working principle is based on the transfer and circulation process of heat energy. In the heating pump 8, there is a special working medium called refrigerant that plays the role of circulating heat energy. The refrigerant absorbs low-temperature heat energy in the evaporator 3 and is compressed in the compressor 1, and the temperature and pressure increase. Subsequently, the refrigerant transfers its high-temperature heat energy to the target that needs to be heated, such as the washing water of the washing equipment, through the heat exchanger. The condenser 2 can be a horizontal shell and tube condenser. The refrigerant condenses on the outer surface of the tube, and the cooling water flows in the tube under the action of the pump. The refrigerant enters from the upper air inlet pipe, condenses into liquid, and flows into the liquid storage tank through the liquid outlet pipe at the bottom of the cylinder. The two ends of the cylinder of the condenser 2 are sealed with end covers, and a water dividing baffle is used in the end cover to realize the multi-pass flow of cooling water. The number of tube bundles of the condenser 2 is an even number, so that the inlet and outlet of the cooling water can be arranged on the same end cover, with the inlet at the bottom and the outlet at the top.

[0035] In order to reduce the working noise of the compressor 1 as much as possible, optionally, a shock-absorbing pad is provided at the bottom of the compressor 1. The bottom of the compressor 1 has a support foot, and the shock-absorbing pad can be arranged at the bottom of the support foot. The shock-absorbing pad can be made of rubber material and has good cushioning performance. The shock-absorbing pad can also be made of other materials, which is not limited here. The working principle of the compressor 1 is roughly as follows: the low-temperature and low-pressure refrigerant is sucked in from the evaporator tube 5, and after the piston is driven by the motor to compress it, the high-temperature and high-pressure refrigerant is discharged to the condenser tube 4, providing power for the refrigeration cycle, thereby realizing the refrigeration cycle of compression, condensation (heat release), expansion, and evaporation (heat absorption).

[0036] The present embodiment also provides a washing device, including an inner tank and the above-mentioned heat pump system, and the washing device can be a heat pump dishwasher. When the compressor 1 is working, the refrigerant expands in the compressor 1, and then enters the condenser 2 through the refrigerant pipeline. The refrigerant releases heat in the condenser 2 to heat the washing water. Subsequently, the refrigerant enters the evaporator 3. After the refrigerant absorbs heat in the evaporator 3, it finally returns to the compressor 1 through the refrigerant pipeline. The refrigerant pipeline is bent and coiled on the outer peripheral side of the compressor 1. The bending radius is determined according to the diameter of the pipeline itself, and the number of bends is determined by the outer diameter of the compressor 1. The refrigerant pipeline is as close to the compressor 1 as possible to achieve the best shock absorption effect. The bending pipeline design of the refrigerant pipeline coiling around the outer peripheral side of the compressor 1 plays a role in assisting the compressor 1 in shock absorption, reducing the vibration amplitude of the compressor 1 when working, extending the service life of the compressor 1, reducing the working noise of the washing device, enhancing the product competitiveness, and improving the user experience.

[0037] Optionally, the washing device further comprises a base, the inner tank is arranged on the base, and the compressor 1 is arranged on the base and is located below the inner tank. Since the evaporator 3 is installed on the side wall of the washing device and is not easy to bend, the rubber tube 63 of the connecting pipe 6 is designed close to the base, so that the evaporator 3 can be placed flat during transportation. In some embodiments, the condenser 2 is arranged below the inner tank, so as to reasonably utilize the installation space in the washing device. Optionally, the evaporator 3 is arranged on the peripheral side of the inner tank, so as to reasonably utilize the structure of the existing dishwasher, reduce the amount of modification, and avoid increasing the height size of the dishwasher.
