Description
技术领域technical field
本发明涉及一种家用电器领域，特别是涉及家用洗衣机的零部件。The invention relates to the field of household appliances, in particular to parts of household washing machines.
背景技术Background technique
热泵是一种将低位热源的热量转移到高位热源的装置，也是全世界备受关注的新能源技术。热泵一般有四部分组成：压缩机、冷凝器、节流阀、蒸发器。其工作过程为：低温低压的液态制冷剂（例如氟利昂），首先在蒸发器（例如空调室内机）里从高温热源（例如常温空气）吸热并气化成低压蒸气。然后制冷剂气体在压缩机内压缩成高温高压的蒸气，该高温高压气体在冷凝器内被低温热源（例如冷却水）冷却凝结成高压液体。再经节流元件（毛细管、热力膨胀阀、电子膨胀阀等）节流成低温低压液态制冷剂。如此就完成一个制冷循环。热泵工作的循环过程中，冷媒的温度会持续上升，为了保证系统的安全性，通常通过降低热泵系统循环次数的方式来保证冷媒的温度不会过高。该方式严重影响热泵系统工作的连续性，需要对系统进行改进。A heat pump is a device that transfers heat from a low-level heat source to a high-level heat source, and it is also a new energy technology that has attracted much attention around the world. A heat pump generally consists of four parts: compressor, condenser, throttle valve, and evaporator. Its working process is: low-temperature and low-pressure liquid refrigerant (such as Freon), first absorbs heat from a high-temperature heat source (such as normal-temperature air) in an evaporator (such as an air-conditioning indoor unit) and vaporizes into low-pressure steam. Then the refrigerant gas is compressed into a high-temperature and high-pressure vapor in the compressor, and the high-temperature and high-pressure gas is cooled by a low-temperature heat source (such as cooling water) in the condenser to condense into a high-pressure liquid. Then it is throttled by throttling elements (capillary tube, thermal expansion valve, electronic expansion valve, etc.) to become a low-temperature and low-pressure liquid refrigerant. In this way, a refrigeration cycle is completed. During the cycle of heat pump operation, the temperature of the refrigerant will continue to rise. In order to ensure the safety of the system, the cycle times of the heat pump system are usually reduced to ensure that the temperature of the refrigerant will not be too high. This method seriously affects the continuity of the work of the heat pump system, and the system needs to be improved.

The compressor 1 , the condenser 2 , the throttle valve 3 , the evaporator 4 and the water cooling tank 5 form a heat pump system of the washing machine.
热泵工作流程为：压缩机1将高压的氟利昂气体送至冷凝器2，高温高压氟利昂气体在冷凝器2中冷凝液化，成为高压液态氟利昂，并在冷凝器2中释放大量热量，使得冷凝器2中的冷凝器制热翅片温度很高；高压液态氟利昂经过冷水降温罐5，进一步降低氟利昂的温度，降温后的高压液态氟利昂经过节流阀3后成为低温低压氟利昂液体，低温低压氟利昂液体在经过蒸发器4后，形成低压氟利昂蒸汽，并在蒸发器4的蒸发器制冷翅片41上吸收大量的热量，使得蒸发器制冷翅片41温度很低；低压氟利昂蒸汽在送到压缩机1，经过压缩机1压缩后，形成高压氟利昂气体，送移动到冷凝器2中，依此循环下去。The working process of the heat pump is: the compressor 1 sends the high-pressure Freon gas to the condenser 2, the high-temperature and high-pressure Freon gas is condensed and liquefied in the condenser 2, and becomes a high-pressure liquid Freon, and releases a large amount of heat in the condenser 2, making the condenser 2 The temperature of the heating fins in the condenser is very high; the high-pressure liquid freon passes through the cold water cooling tank 5 to further reduce the temperature of the freon, and the cooled high-pressure liquid freon becomes a low-temperature and low-pressure freon liquid after passing through the throttle valve 3, and the low-temperature and low-pressure freon liquid is After passing through the evaporator 4, low-pressure Freon vapor is formed, and a large amount of heat is absorbed on the evaporator cooling fin 41 of the evaporator 4, so that the temperature of the evaporator cooling fin 41 is very low; the low-pressure Freon vapor is sent to the compressor 1, After being compressed by the compressor 1, high-pressure Freon gas is formed, which is sent to the condenser 2 and circulated accordingly.
热泵循环系统的工作，使得冷凝器加热翅片21温度很高，蒸发器制冷翅片42温度很低。洗衣机烘干工作时，风机61将滚筒7中的湿空气抽出，经过进风管道62抽送到蒸发器4中，湿热空气经过蒸发器4中的蒸发器制冷翅片41时，湿热空气中的水分和干洗溶剂液化，经底部钣金凹槽汇流后的混合液体流入到油水分离器63中，经过油水分离器63的分离作用，水经过排水管道，直接排出到洗衣机外部，干洗溶剂经过管道，回收到干洗溶剂储存箱中。湿热空气经过蒸发器4液化后，成为干燥的空气，干燥的空气继续向冷凝器2中流动，经过冷凝器2中的冷凝器制热翅片21，成为干燥的热空气，干燥的热空气从出风管道65回到滚筒7中，将衣服上的水分或干洗溶剂带出，再次经过风机61，蒸发器4和冷凝器2，再回到滚筒7中，如此往复循环，从而将衣物烘干。The work of the heat pump circulation system makes the temperature of the condenser heating fin 21 very high, and the temperature of the evaporator cooling fin 42 is very low. When the washing machine is drying, the fan 61 extracts the humid air in the drum 7, and then pumps it into the evaporator 4 through the air inlet pipe 62. When the hot and humid air passes through the cooling fins 41 of the evaporator in the evaporator 4, the moisture in the hot and humid air The mixed liquid flows into the oil-water separator 63 after converging with the dry-cleaning solvent, and the mixed liquid flows into the oil-water separator 63. After the separation of the oil-water separator 63, the water passes through the drainage pipe and is directly discharged to the outside of the washing machine. The dry-cleaning solvent passes through the pipe and is recycled. into the dry cleaning solvent storage tank. After the hot and humid air is liquefied by the evaporator 4, it becomes dry air, and the dry air continues to flow into the condenser 2, passes through the condenser heating fins 21 in the condenser 2, and becomes dry hot air, and the dry hot air flows from The air outlet duct 65 returns to the drum 7 to take out the moisture or dry-cleaning solvent on the clothes, passes through the fan 61, the evaporator 4 and the condenser 2, and then returns to the drum 7, so that the cycle is repeated, thereby drying the clothes .
