Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.

[0040] The embodiments of the present application provide a washing and drying device and a self-cleaning control method, device and storage medium thereof, which are described in detail below.

[0041] A washing and drying device is a device that integrates the functions of washing and drying clothes. When drying clothes, impurities such as lint on the clothes will follow the airflow into the drying duct; lint and other impurities will remain in the drying duct, and after accumulating to a certain extent, they will cause blockage in the drying duct. In the prior art, the blockage is reduced by manually cleaning the lint and other impurities on the filter in the drying duct; however, the lint and other impurities may accumulate in some areas that cannot be removed by hand, and then gradually accumulate; therefore, the prior art has the technical problem of incomplete cleaning. Lint and other impurities accumulated in areas that cannot be removed are prone to breed bacteria and cause health problems. At the same time, they will also aggravate the blockage of the drying duct, resulting in technical problems such as inability to dry and / or poor drying effect.

[0042] To this end, an embodiment of the present application provides a self-cleaning control method for a washing and drying device to solve the technical problem of incomplete cleaning of impurities such as lint.

[0043] First, let's introduce the washing and drying equipment. The washing and drying equipment includes an inner drum, a drying duct, and a drying assembly. The inner drum is connected to the drying duct; the inner drum is connected to the drying assembly through the drying duct. The drying assembly includes a heating element for generating heat and a fan for driving air circulation. Under the action of the fan, hot air enters the inner drum to heat and dry the clothes; the humid air flow enters the drying duct and is returned to the heating element to dry the clothes. In addition to water, the humid air flow also contains impurities such as lint.

[0044] The washing and drying device also includes a controller, which is used to control the steps in the self-cleaning control method proposed in the embodiment of the present application. For example, the controller is used to control the motor that drives the inner drum to rotate; for example, the controller is also used to control the drying component to perform the drying task.

[0045] Specifically, Figure 1 As shown, it is a schematic diagram of an embodiment of a washing and drying device and a self-cleaning control method thereof in an embodiment of the present application; the self-cleaning control method comprises:

[0046] S100, obtaining a self-cleaning instruction;

[0047] The self-cleaning command can be generated by the user through the APP, operation panel or the washing and drying equipment after the preset conditions are triggered;

[0048] S200, based on the self-cleaning instruction and when the water level in the inner drum reaches a preset water level, controlling the inner drum to rotate at a preset speed and run for a first preset time, so that the water in the inner drum enters the drying air duct.

[0049] In an embodiment, when a self-cleaning instruction is executed, the water level in the inner drum reaches a preset water level, and the inner drum rotates at a preset speed and runs for a first preset time, so that the water in the inner drum enters the drying air duct under the action of centrifugal force, so that the lint and other impurities in the drying air duct are separated from the components in the drying air duct (such as corners, walls to which lint and other impurities are attached, etc.) under the action of centrifugal force, and are carried out of the drying air duct under the action of water flow, thereby clearing away the lint and other impurities in the difficult-to-clean areas in the drying air duct, thereby improving the cleaning degree in the drying air duct.

[0050] In the technical solutions of some embodiments, the inner drum can have at least one state when executing the self-cleaning instruction, that is, the first state of rotating at a preset speed and running for a first preset time; the inner drum can also have a second state when executing the self-cleaning instruction, that is, pausing the rotation or running at another speed lower than the preset speed and running a second state between the third presets; within a self-cleaning cycle, the inner drum switches between the first state and the second state; the first preset time and the third preset are set according to a preset ratio. When the inner drum is operated in this way, the centrifugal force is changed, which is conducive to the detachment of impurities such as lint from the drying air duct in the change of water flow and the detached impurities such as lint flow out of the drying air duct.

[0051] In some other embodiments, the inner drum can have at least one state when executing the self-cleaning instruction, that is, a first state that rotates at a preset speed and runs for a first preset time; the inner drum can also have a second state when executing the self-cleaning instruction, that is, another speed that is opposite to the preset speed and runs a third state between a fourth preset. In a self-cleaning cycle, the inner drum switches between the first state and the third state; the first preset time and the fourth preset are set according to a preset ratio. When the inner drum is operated in this way, the centrifugal force is changed, which is conducive to the detachment of impurities such as lint from the drying air duct in the change of water flow and the detached impurities such as lint flow out of the drying air duct.

[0052] In the above embodiment, the preset water level is related to the interface position between the drying duct and the inner drum; that is, the lower the interface position, the lower the preset water level is set; the higher the interface position, the higher the preset water level is set. In specific implementation, the preset water level is determined by testing the corresponding equipment so that sufficient water can enter the drying duct when the inner drum rotates at a preset speed.

[0053] As an optional implementation of the above embodiment, Figure 2 As shown, the obtaining of the self-cleaning instruction includes:

[0054] S111, obtaining current blockage information of the drying air duct;

[0055] S112: If the current blockage information matches the preset blockage information, a self-cleaning instruction is obtained.

[0056] In this embodiment, by obtaining the current blockage information in the drying air duct; when the current blockage cleaning meets the preset blockage information, a self-cleaning instruction is obtained. In this embodiment, the drying device can automatically detect the current blockage information of the drying air duct, such as wind speed or wind pressure. For example, when the wind speed is lower than the preset wind speed, the current blockage information meets the preset blockage information.

[0057] In this embodiment, when executing the self-cleaning instruction, it is necessary to inject washing water of a preset water level into the inner drum.

[0058] As an optional implementation of the above embodiment, Figure 3 As shown, controlling the inner drum to rotate at a preset speed and running for a first preset time includes:

[0059] S211, determining the preset speed and / or the first preset time according to the current congestion information;

[0060] S212, controlling the inner drum to rotate at a preset speed determined according to the current congestion information and to run for a first preset time determined according to the current congestion information.

[0061] That is, in an embodiment, the preset speed and / or the first preset time are determined according to the blockage situation in the drying air duct, that is, the magnitude of the centrifugal force and / or the duration of the water flow flushing are determined to flush out the impurities such as fluff inside. For example, when the wind speed is relatively low, the larger the preset speed and / or the longer the first preset time. In some embodiments, the blockage information is graded, such as low (wind speed is greater than the first preset wind speed), medium (wind speed is less than or equal to the first wind speed and greater than the second wind speed) and high (wind speed is less than or equal to the second wind speed and greater than the third wind speed), and the corresponding preset speeds are, from small to large, the first preset speed, the second preset speed and the third preset speed, and the corresponding first preset times are, from small to large, T1, T2 and T3. Specifically, in different models, the wind speed, preset speed and first preset time are set differently, which can be determined through experiments and set in the memory of the washing and drying equipment.

[0062] Reference Figure 4 As shown, the obtaining of the self-cleaning instruction includes:

[0063] S121, obtaining the current operation stage of the washing and drying equipment;

[0064] S122: If the current operation stage is the washing completion stage, a self-cleaning instruction is obtained.

[0065] In some embodiments, the self-cleaning instruction is automatically generated after the washing is completed. That is, the washing and drying equipment is preset with a corresponding program. After each washing is completed, since there is washing water in the inner drum, the drying duct can be cleaned without adding water or with less water, so that the drying duct is cleaned regularly and the operating efficiency of the drying equipment is improved.

[0066] In an embodiment, the washing and drying device includes a washing stage and a drying stage. The washing stage and the drying stage can be performed separately or in combination. For example, the user can select a washing and drying process, that is, washing first and then drying. The washing stage includes a washing process stage and a washing completion stage. The washing completion stage can be a stage after the last rinsing of the washing and drying device is completed and before the last drainage in the washing stage.

[0067] In an embodiment, when the washing and drying equipment starts to execute the self-cleaning control method, the rotation speed of the inner drum is increased compared to that during washing, that is, the preset rotation speed is greater than the rotation speed during normal washing, so as to generate sufficient centrifugal force to separate impurities such as lint in the drying air duct from the drying air duct.

[0068] As the technical solution of the above embodiment, Figure 5 As shown, based on the self-cleaning instruction, when the water level in the inner drum reaches a preset water level, the inner drum is controlled to rotate at a preset speed and run for a preset time so that the water in the inner drum enters the drying air duct, and the self-cleaning control method further includes:

[0069] S300, controlling the reverse airflow to enter the drying air duct and running for a second preset time; wherein the reverse airflow is opposite to the direction of the drying airflow of the washing and drying device in the clothes drying mode.

[0070] In the embodiment, the water flow flushes the impurities such as lint in the dead corners and attached to the channel wall to the state of being out of the drying duct, so that the lint and other impurities are in a free state; after the water flow flushing is completed, the lint and other impurities in the free state are flushed out of the drying duct by blowing the reverse air flow for a second and set time, further removing the lint and other impurities that are not carried out by the water flow, thereby improving the cleaning degree.

[0071] In an embodiment, the reverse airflow is the airflow generated by the reverse rotation of the drying fan in the washing and drying device. When the drying fan in the washing and drying device rotates forward, the airflow enters the drying air duct from the inner drum. When the drying fan in the washing and drying device rotates reversely, the airflow enters the inner drum from the drying air duct.

[0072] In an embodiment, the second preset time may be preset or determined according to the blockage information. The flow rate of the reverse airflow may also be preset or determined according to the blockage information.

[0073] As an optional real-time method of the above embodiment, Figure 6 As shown, based on the self-cleaning instruction, when the water level in the inner drum reaches a preset water level, the inner drum is controlled to rotate at a preset speed and run for a preset time so that the water in the inner drum enters the drying air duct. The self-cleaning control method includes:

[0074] S400, obtaining the amount of impurities thrown out;

[0075] The amount of impurities can be determined by a light curtain installed at the inlet of the drying air duct (the inlet of the gas during drying). The amount of impurities can be determined by the time the light curtain is blocked. The amount of impurities can also be determined by the turbidity of a turbidity sensor installed at the inlet of the drying air duct (the inlet of the gas during drying).

[0076] The step of controlling the drying air duct to enter a reverse airflow and running the reverse airflow for a second preset time comprises:

[0077] S310: If the number exceeds a preset number, control the drying air duct to enter a reverse airflow and run for a second preset time.

[0078] In this embodiment, the amount of impurities thrown out is detected to determine the amount of impurities in the drying duct. When the amount is large, the drying duct can be controlled to enter a reverse airflow and run for a second preset time to generate a reverse airflow for reverse purge.

[0079] As the technical solution of the above embodiment, Figure 6 As shown, the self-cleaning control method further includes: S500, if the number is less than a preset number, controlling the washing and drying device to enter a drainage mode. That is, when the number of impurities is small, the reverse airflow may not be allowed to enter the drying air duct temporarily, and drainage may be started directly to discharge the impurities along with the water.

[0080] In an embodiment, in order to ensure the thoroughness of the cleaning process, the washing and drying equipment is provided with a drainage module, and the drainage module includes a drainage channel and a drainage hole for discharging dirt and water generated during the cleaning process. Dirt and accumulated water are guided to the main drainage pipe of the washing machine through the drainage channel for discharge, ensuring that the dirt after cleaning no longer remains in the channel. The washing and drying equipment is provided with a drainage channel; the drainage channel is connected to the outer drum; there is a radial gap between the inner drum and the outer drum, and the space of the inner drum is connected to the gap. The drying channel is also connected to the gap. Washing water is filled between the gap and the inner drum; when the inner drum rotates at a preset speed, the water in the gap enters the drying air duct under the action of centrifugal force, and the impurities cleaned enter the gap; then the impurities are discharged through drainage.

[0081] The washing and drying equipment is also configured to regularly remind users to check and clean the drain outlets and filters to prevent debris from clogging the drainage system, thereby ensuring long-term unobstructed access to the drying channel.

[0082] In order to better implement the self-cleaning control method of the washing and drying equipment in the embodiment of the present application, on the basis of the self-cleaning control method of the washing and drying equipment, the embodiment of the present application also provides a self-cleaning control device for the washing and drying equipment, such as Figure 7As shown, the self-cleaning control device of the washing and drying equipment includes:
