Detailed Description
As shown in fig. 1 and 2, the utility model relates to a hot air circulating system for clothes nursing machine, including clothes nursing inner bag 1, install heat pump 2, heat transfer device 3, inlet air channel 4 and centrifugal air-out device 5 in clothes nursing inner bag below. The heat pump 2, the heat exchange device 3, the air inlet channel 4 and the centrifugal air outlet device 5 are all arranged on the bottom frame 6, and a circulating air inlet 11 and a circulating air return 12 are arranged on the bottom surface of the clothes nursing liner 1.
As shown in fig. 3, the heat pump 2 includes a compressor 21, a condenser 24, a check valve 23, an electronically controlled expansion valve 25, and an evaporator 22. The compressor 21, the condenser 24, the one-way valve 23, the electronic control expansion valve 25 and the evaporator 22 are connected in sequence by a pipeline 26 to form a closed system. The refrigerant continuously circulates and flows in the system, changes, and exchanges heat in the air circulation system of the clothing care secret closed type. A temperature probe 27 is mounted on the wall of the conduit before the refrigerant inlet of the evaporator 22 of the condenser 24. Specifically, under the driving of the compressor 21, the refrigerant in a vapor state flows in the pipe from the compressor 21 to the condenser 24 to the check valve 23 to the motor-operated expansion valve 25. (the electric expansion valve 25 is equivalent to a capillary tube with a variable aperture of the shell) the refrigerant vapor is blocked by the small aperture of the electric expansion valve 25, and the refrigerant vapor is simultaneously acted by the high pressure of the compressor 21, so that the refrigerant is changed from a vapor state to a liquid state and releases heat. The condenser 24 generates heat by heat exchange with the condenser 24. At the same time, due to the action of the check valve 23, the liquid refrigerant flows into the evaporator 22 through the small hole of the electronically controlled expansion valve 25, due to the large volume of the evaporator 22 channel. The liquid refrigerant is subjected to a reduced pressure, expands and diffuses in volume, evaporates, and changes from liquid to gas, which is a heat absorption process. The temperature of the evaporator 22 decreases. Under the driving of the compressor 21, the refrigerant in the vapor state returns to the compressor 21 and is driven to the condenser 24, thereby achieving the purpose of continuously circulating heating and cooling. The temperature around the condenser 24 is thus relatively high. The air passing through will be heated. The temperature around the evaporator 22 is low, and moisture contained in the hot and humid air is condensed into water when the air passes through the evaporator 22.
