Document Type and Number:
WIPO Patent Application WO/2022/062350
Kind Code:
A1
Abstract:
A washing and drying integrated machine (1), comprising a box body (2), a washing tub (3), an air circulation path (20), an air blowing part (21) that enables air to circulate by means of drawing the air in the washing tub (3) into the air circulation path (20) and returning the air to the washing tub (3), a heat pump (25), a filter (F2) that is configured in the air circulation path (20) and can be detached to the outside of the box body (2), a refrigerant temperature measuring part (35) that measures the temperature of a refrigerant that is compressed by a compressor (26) of the heat pump (25), and a control part (30) that controls the air blowing part (21) and the heat pump (25) to perform a drying operation. When the temperature measured by the refrigerant temperature measuring part (35) after a predefined time from the start of a drying operation or an increase in temperature is less than a predefined threshold, the control part (30) determines that there is no filter (F2) in the air circulation path (20).
