Clothing processing equipment

Abstract

The operation of the heat pump can be appropriately controlled by determining the dryness of the clothes. [Solution] The garment processing apparatus comprises a storage tank in which garments are stored, an air passage for supplying air to the storage tank, a heat pump for dehumidifying and heating the air flowing through the air passage, a solenoid valve which constitutes part of the heat pump and adjusts the amount of refrigerant flowing between the condenser and evaporator of the heat pump, a humidity detection unit for detecting the humidity in the air passage, and a control unit which controls the heat pump to perform an operation including a drying process for drying the garments in the storage tank. The control unit controls the solenoid valve based on the detection result of the humidity detection unit during the execution of the drying process.

Claims

1. A storage tank in which clothing is stored, A duct for supplying air to the aforementioned storage tank, A heat pump that dehumidifies and heats the air flowing through the aforementioned air passage, A solenoid valve, which constitutes part of the heat pump, is used to adjust the amount of refrigerant flowing between the condenser and evaporator of the heat pump. A humidity detection unit for detecting the humidity inside the air passage, The system includes a control unit capable of controlling the heat pump to perform an operation that includes a drying process for drying the clothes in the storage tank, The control unit controls the solenoid valve based on the detection result of the humidity detection unit during the execution of the drying process. Garment processing device.

2. The storage tank further includes a weight detection unit for detecting the weight of the clothing inside, The control unit does not control the solenoid valve based on the detection result of the humidity detection unit if the weight detected by the weight detection unit is greater than or equal to a predetermined value. The garment processing apparatus according to claim 1.

3. An inlet temperature detection unit detects the inlet temperature, which is the temperature of the refrigerant flowing on the inlet side of the evaporator. The system further includes an outlet temperature detection unit that detects the outlet temperature, which is the temperature of the refrigerant flowing on the outlet side of the evaporator. The control unit controls the solenoid valve based on the temperature difference, which is the difference between the outlet temperature and the inlet temperature. The garment processing apparatus according to claim 1.

4. The control unit controls the solenoid valve after starting the drying process so that the temperature difference becomes a first temperature difference, and then controls the solenoid valve so that the temperature difference becomes a second temperature difference which is smaller than the first temperature difference. The garment processing apparatus according to claim 3.

5. The system further includes an airflow temperature detection unit that detects the temperature inside the airflow path, If the control unit determines that there is an abnormality in the humidity detection unit, it controls the solenoid valve based on at least one of the detection result of the air passage temperature detection unit and the elapsed time of the drying process. The garment processing apparatus according to claim 1.

6. The control unit can control the solenoid valve again after a predetermined waiting period has elapsed since the initial control. The garment processing apparatus according to claim 1.
