This embodiment provides a control method of a clothes treatment device, where the clothes treatment device includes an inner tub and a heat pump module. The clothes treatment apparatus of this embodiment has an air washing program, and during the process of executing the air washing program, the heat pump module is controlled to be turned on to dehumidify the circulating air introduced into the inner cylinder.

In this embodiment, during the process of performing the air washing procedure, the clothes treating apparatus dehumidifies the circulating air by using the heat pump module, which saves water resources compared with the method of removing moisture by entering condensed water in the prior art. The cooling effect of the circulating air is remarkable, resulting in a better dehumidification effect.

Further, the clothes treatment device of this embodiment further includes an electric heating device. During the execution of the air washing program, the electric heating device is controlled to be turned on, and cooperates with the heat pump module to heat the circulating air passing into the inner cylinder.

In this embodiment, the electric heating device and the heat pump module cooperate to heat the circulating air, so that the inside of the inner cylinder can reach a higher temperature, so that the fibers of the clothes can be fully stretched, the cleaning effect of the clothes is better, and the drying effect of the clothes can be increased at the same time. Elasticity makes the fabric of the garment softer.

Specifically, in this embodiment, the clothes treatment device includes an air duct communicating with the inner cylinder, and a fan is arranged in the air duct. During the operation of the air washing program, the fan continues to run, forming circulating air between the air duct and the inner cylinder. The heat pump module includes an evaporator and a condenser. After the circulating air is drawn out from the inner cylinder, it is cooled down through the evaporator along the air duct, and the water vapor in it is condensed and separated from the circulating gas. The dehumidified circulating gas is reheated by the condenser, and then reheated by the electric heating device to obtain high-temperature dry air, which enters the inner cylinder again to wash the clothes.

As shown in Figure 1, in this embodiment, after the air washing program is started, the electric heating device is controlled to be turned on to heat the circulating air introduced into the inner cylinder. The air is dehumidified and heated simultaneously with the electric heating device.

Preferably, the clothes treating apparatus further includes a humidity sensor for detecting the humidity of the circulating air, and when the humidity detected by the humidity sensor is higher than a first preset humidity, the heat pump module is controlled to be turned on.

In the above solution, after the air washing program is started, the electric heating device is preferentially turned on to heat the circulating air, so that the temperature of the circulating air rises at a faster heating rate, thereby rapidly increasing the temperature inside the inner cylinder. At the same time, in the initial stage of the air washing process, the humidity of the circulating air does not rise significantly, so the heat pump module can be turned on for dehumidification first.

In this embodiment, a humidity sensor is set to detect the humidity of the circulating air, and when the humidity of the circulating air is higher than the first preset humidity, the heat pump module is turned on to perform dehumidification, so as to prevent the humidity from rising further, and the humidity of the circulating air can be controlled within a certain range inside, to prevent the high humidity of the circulating air from affecting the cleaning effect of the clothes.

For clothes of different materials or weights, in order to achieve a similar cleaning effect, the temperature and cleaning time required for air washing are different. The clothes treatment device determines the working time of the electric heating device according to the material and/or weight information of the laundry. , so that different clothes can achieve good cleaning effect when air-washed in the clothes treatment device.

In a further solution of this embodiment, the clothes treating device further includes a spray device capable of spraying water into the inner tub. In the process of executing the air washing program, the spray device is controlled to spray water into the inner cylinder for a certain period of time. Preferably, the spray device sprays water into the inner cylinder in the form of a spray.

In the above solution, the clothes treatment device sprays water into the inner tub during the execution of the air washing program, and the sprayed water will form steam under the action of the high-temperature air, quickly soaking the clothes, thereby improving the cleaning effect of the clothes, and It can also play a certain bactericidal effect. Spraying water into the inner drum in the form of a spray can form water vapor more quickly, so that the clothes can be soaked more quickly and evenly, and the cleaning effect can be further improved.

In this embodiment, the water spraying duration of the spraying device can be a set value in the program. For example, after the spraying device is turned on, water spraying continues for 30 seconds, and the spraying device is controlled to stop spraying water.

Preferably, the clothes treating device determines the water spraying time of the spraying device according to the material and/or weight information of the clothes in the inner tub. When the water absorption of the laundry is good or the amount of laundry is large, the water spraying time of the spray device is controlled to be longer, that is, the water spraying amount is increased, which can ensure that the laundry is fully soaked, thereby effectively improving the cleaning of the laundry. Effect.

Further, after the air washing program is started, the electric heating device is firstly controlled to be turned on to heat the circulating air introduced into the inner cylinder.

After the electric heating device is turned on, after a fourth preset time T ₄ , the spray device is controlled to be turned on to spray water into the inner cylinder. Alternatively, the clothes treatment device further includes a temperature sensor for detecting the temperature of the circulating air, and when the temperature detected by the temperature sensor reaches the second preset temperature, the spraying device is controlled to be turned on to spray water into the inner tub.

In the above scheme, the electric heating device is first turned on to heat the circulating air, and after the electric heating device has been working for a period of time, the spraying device is turned on to spray water into the inner cylinder, so as to ensure that when the water is sprayed, the interior of the inner cylinder has reached a higher temperature, and the sprayed The water can be quickly vaporized to form steam.

In this embodiment, the spray device is controlled to be turned on by means of timing. After the air washing program is started, first turn on the electric heating device to heat the circulating air. After 3 minutes, turn on the spraying device and spray water into the inner cylinder in the form of a spray for 30 seconds.

Preferably, the clothes treating apparatus determines the _fourth preset time T4 or the second preset temperature according to the material and/or weight information of the clothes in the inner tub. The clothing treatment device of this embodiment determines the timing of the spraying device to start spraying water according to the material and/or weight of the laundry, so as to ensure that the sprayed water can be quickly vaporized in the inner tub, fully soaks the clothing, and ensures that the clothing is safe and clean. cleaning effect.

In a further solution of this embodiment, after the clothes treatment device is turned on, if a signal for the user to select the air washing program is received, during the operation of the clothes treatment device, the heat pump module is controlled to be turned on, and the circulating air entering the inner cylinder is controlled to be turned on. Dehumidification.

Specifically, the user puts the clothes into the inner tub, turns on the clothes treatment device, and can judge by himself whether the air washing program needs to be run according to the type of the clothes to be washed. When the laundry cannot be washed with water, the user can operate the laundry treatment device to select an air washing program, and then activate the laundry treatment device to start running.

The laundry treatment device receives the signal of the user selecting the air washing program, determines that the air washing program needs to be run, and then turns on the fan when receiving the start signal to generate circulating air, and simultaneously turns on the electric heating device to heat the circulating air. For a period of time after the electric heating device is turned on, the spray device is controlled to spray water into the inner cylinder in the form of a spray to fully wet the clothes. Turn on the heat pump module in the middle stage of the air washing program operation process, control the heat pump module to work continuously for a period of time, dehumidify the circulating air, and heat the circulating air at the same time with the electric heating device. After the heat pump module is turned off, the electric heating device remains on until the air washing program ends, and the electric heating device and the fan are controlled to stop working.

In this embodiment, the clothes treating apparatus has an air washing program, and the clothes that cannot be washed with water are washed by passing high-temperature air into the inner cylinder. In the initial stage of the air washing program, water is sprayed into the inner cylinder in the form of a spray, and the sprayed water is rapidly vaporized to form steam in the high temperature environment of the inner cylinder, which evenly wets the clothes, improves the cleaning effect of the clothes, and plays a role in Certain bactericidal effect. The heat pump module is turned on for a period of time in the middle stage of the air washing program, dehumidifies the circulating air, and heats the circulating air at the same time as the electric heating device. The use of a heat pump module instead of the method of continuous cooling and dehumidification of condensed water in the prior art has a more significant cooling effect on the circulating air, so that the removal of moisture in the circulating air is more effective, and the cleaning effect of air washing for clothes is better. At the same time, since it is not necessary to continuously feed condensed water during the operation of the air washing program, water resources are saved.

Embodiment 2

After a certain period of time, the electric heating device is controlled to be turned off, and the heat pump module is controlled to be turned on simultaneously. Dehumidifies the circulating air that is passed into the inner cylinder, and heats the dehumidified air.

In a further solution of this embodiment, after the electric heating device continues to work for a _third preset time T3 after being turned on, the electric heating device is controlled to be turned off and the heat pump module is turned on.

In another solution of this embodiment, the clothes treatment device further includes a temperature sensor for detecting the temperature of the circulating air, and when the temperature detected by the temperature sensor reaches a first preset temperature, the electric heating device is controlled to be turned off, Turn on the heat pump module.

Keep the temperature of the circulating air at a high level to ensure the cleaning effect of the clothes.

Compared with the above-mentioned first embodiment, the solution of this embodiment has a relatively slow heating rate in the inner cylinder because there is no simultaneous heating stage of the electric heating device and the heat pump module, and the running time of the air washing program is longer. However, for clothes made of some materials, rapid heating may damage the clothes. The solution of this embodiment can achieve a good cleaning effect by air washing on the premise of effectively protecting the clothes.

In a preferred solution of this embodiment, the clothes treating apparatus determines the _third preset time T3 or the first preset temperature according to the material and/or weight information of the clothes in the inner tub.

After the heat pump module runs for a period of time, the laundry in the inner tub is completely dry, that is, the air washing process of the laundry is completed.

In this embodiment, when the laundry treatment device performs the air washing procedure, the electric heating device is used to heat the circulating air to reach the required temperature, and then the electric heating device is turned off and the heat pump module is turned on independently. The heat pump module dehumidifies and heats the circulating air at the same time. Circulates the air temperature while removing moisture from it.
