Referring to fig. 1 to 6, the present utility model provides a laundry care machine 100, comprising: a box 1001, a main control unit 1002, a first care unit 1003 and a second care unit 1004.

As a working mode, when the laundry care machine 100 starts a low-temperature care mode, the main control unit 1002 controls the humidifying assembly 2 to work to generate normal-temperature water mist, and controls the dehumidifying assembly 1 to not work, and the normal-temperature water mist performs low-temperature care on the laundry in the box 1001; when the clothes care machine 100 starts a high Wen Huli mode, the main control unit 1002 controls the humidifying assembly 2 to work to generate normal-temperature water mist, and simultaneously controls the dehumidifying assembly 1 to work to heat the inside of the box 1001, specifically controls the refrigerating plate 11, the heater 13 and the second fan 15 of the dehumidifying assembly 1 to work, the first fan 14 does not work or works at a low speed, the temperature of the dehumidifier 12 is reduced to be lower than 0 ℃ through detection of the first temperature sensor, condensed water on the surface of the dehumidifier 12 is cooled to be frozen, the dehumidifier 12 stores cold to transfer more heat to the heater 13, so that the heater 13 generates a large amount of heat, and high-temperature care is performed on clothes; when the laundry machine 100 starts a drying mode, since the temperature of the dehumidifier 12 has fallen below 0 ℃, the ice stored on the surface of the dehumidifier 12 can be used to condense water vapor, and the first fan 14 can operate at a high speed, so as to accelerate the drying speed; the wind speed of the first fan 14 is adjusted in time according to the temperature rise of the dehumidifier 12, and when the temperature of the dehumidifier 12 is higher than a preset temperature, the rotating speed of the first fan 14 is reduced, so that the temperature of the dehumidifier 12 is reduced, and the dehumidification amount is increased; when the temperature of the dehumidifier 12 is lower than a predetermined temperature, the rotation speed of the first fan 14 is increased, the dehumidification rate is increased, and the drying is accelerated, thereby realizing the optimization of the dehumidification rate and the dehumidification amount.

In some application examples, the dehumidifying assembly 1 further includes a dew point sensor (not shown), where the dew point sensor is disposed at an air inlet of the first fan 14 or between the first fan 14 and the dehumidifier 12, and is used for detecting a dew point temperature of air entering the dehumidifier 12, and feeding back to the main control unit 1002, so as to control the temperature of the dehumidifier 12 below the dew point temperature by controlling the rotation speed of the first fan 14, and adjusting the flow rate of air flowing through the dehumidifier 12, so as to optimize the dehumidifying speed and the dehumidifying amount.

As a mode of operation, when the laundry machine 100 starts the drying mode, the main control unit 1002 controls the cooling sheet 11, the dehumidifier 12 and the first fan 14 to operate, the temperature of the dehumidifier 12 gradually increases from 0 degrees or less, the main control unit 1002 collects the dew point temperature of the air entering the dehumidifier 12 detected by the dew point sensor, controls the rotational speed of the first fan 14 according to the temperature, and adjusts the flow rate of the air flowing through the dehumidifier 12 to control the temperature of the dehumidifier 12 to be below the dew point temperature. The introduction of dew point temperature may be a floating adjustment of the predetermined temperature of the dehumidifier 12 in the drying mode, which varies the rotational speed of the first fan 14. For example, when the dew point temperature is 60 degrees, and when the temperature of the dehumidifier 12 is higher than 60 degrees, the rotation speed of the first fan 14 is reduced, so that the temperature of the dehumidifier 12 is reduced, and the dehumidification amount is increased; when the temperature of the dehumidifier 12 is lower than 30 degrees, the rotation speed of the first fan 14 is increased, the dehumidification rate is increased, and the drying is accelerated, so that the optimization of the dehumidification speed and the dehumidification amount is realized.
