[0059] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0060] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0061] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0062] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated.

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0063] Sterilization and wrinkle removal are important indicators of the treatment effect of current clothing treatment equipment. In the prior art, the existing high-temperature sterilization and pasteurization programs have a long washing time, high power consumption, and cannot remove wrinkles; sterilization program washing easily causes protein stains to denature and turn yellow; air washing has a worse wrinkle removal effect than steam washing. Therefore, steam washing has become an important functional option for clothing treatment equipment. Water consumption is an important indicator in steam washing, which not only affects the energy consumption of clothing treatment equipment, but also affects the sterilization and wrinkle removal effects. If the water is insufficient, the sterilization and wrinkle removal will be incomplete; if the water is excessive, the energy consumption will increase. Therefore, accurate water intake is the key to steam washing. However, due to the limitation of the accuracy of the water level sensor, how to accurately judge the water intake has become a technical problem that needs to be solved in steam washing. To this end, the embodiment of the present application provides a control method, device, clothing treatment equipment and storage medium for steam washing.

[0064] Specifically, the clothing processing device is used to steam, iron and wash clothing; the clothing processing device may be a washing machine, a dryer or an all-in-one washing and drying machine.

[0065] The clothing processing device includes a water inlet valve, a water inlet pipe, a drum, a motor and a controller. The water inlet valve is connected to the water inlet pipe. The water inlet pipe is configured to inject water into the drum. The motor is configured to drive the drum to rotate. The controller is configured to execute the control method of steaming and ironing described in the embodiment of the present application. The clothing processing device also includes a heating device, such as a heating pipe, etc., which is used to heat the air in the drum so that the temperature in the drum reaches the temperature required for steaming and ironing. The clothing processing device also includes a drainage pump, which is used to drain the water in the drum.

[0066] In the technical solution of the embodiment of the present application, Figure 1The clothes processing device shown in the figure will enter step S10-water inlet stage, step S20-water inlet confirmation stage, step S30-water replenishment stage, step S40-steaming and ironing stage, and step S50-drainage stage when performing steaming and ironing. In some embodiments, the clothes processing device will also enter step S60-ironing stage.

[0067] like Figure 2 As shown, the present application proposes a steaming and ironing control method for a clothing processing device, comprising:

[0068] S11, when the water inlet volume reaches the set water inlet volume, the water inlet valve is controlled to close;

[0069] S21, obtaining a first water level frequency value in the cylinder;

[0070] S22, controlling the motor to rotate; the motor is used to drive the cylinder;

[0071] S23, after a first preset time, controlling the motor to stop rotating;

[0072] S24, after a second preset time period, obtaining a second water level frequency value in the cylinder;

[0073] S25, obtaining a first difference between the first water level frequency value and the second water level frequency value;

[0074] S311, if the first difference is less than a first preset difference, controlling the water inlet valve to open;

[0075] S312, after a third preset time, controlling the water inlet valve to close;

[0076] S313, controlling the motor to rotate again;

[0077] S314, after a fourth preset time, controlling the motor to stop rotating;

[0078] S315, after a fifth preset time period, obtaining a third water level frequency value in the cylinder;

[0079] S41, controlling the clothes processing device to enter the steaming and ironing stage with the third water level frequency value as a reference water level frequency value;

[0080] S42: If the first difference is greater than a first preset difference, control the clothes processing device to enter the steaming and ironing stage using the second water level frequency value as a reference water level frequency value.

[0081] In the technical solution of the embodiment of the present application, after the water intake reaches the set water intake, the water intake valve is closed and the water intake is stopped; then the first water level frequency value in the drum is obtained; then the motor is controlled to start and the motor rotates, so that the clothes in the drum start to absorb water; after the motor rotates for a first preset time, the motor stops; and after a second preset time, the second water level frequency value in the drum is obtained again; the first difference between the second water level frequency value and the first water level frequency value is obtained; by comparing the first difference with the first preset difference, it is judged whether the water volume meets the steaming and ironing requirements of the clothes. If the first difference is less than the first preset difference, it means that the water intake is insufficient, and at this time, after executing steps S311 to S315, the steaming and ironing stage is entered; if the first difference is greater than the first preset difference, it means that the water intake meets the demand, and the steaming and ironing stage is entered without adding water; therefore, in the technical solution of the present application, after the water intake is completed, the water replenishment confirmation stage is entered, and the steaming and ironing stage is entered after the water replenishment confirmation, so as to accurately judge whether the water intake in the drum meets the steaming and ironing requirements.

[0082] It should be noted that, in the embodiment, the set water inlet is the minimum water inlet; the minimum water inlet is used as the water consumption for steaming and ironing, so that the temperature rise rate during steaming and ironing is fast, so that the drum can quickly enter the high-temperature steam.

[0083] It should be noted that, in the embodiment, the difference between the second water level frequency value and the first water level frequency value is obtained by subtracting the first water level frequency value from the second water level frequency value.

[0084] In the above embodiments, the set water intake, the first preset time, the second preset time, the third preset time, the fourth preset time, and the first preset difference are all preset parameters, which are factory parameters in the clothing processing device or parameters set by the user according to needs, and are not specifically limited here. In some embodiments, the first preset difference can be 0.03Khz.

[0085] In the above steps, step S11 belongs to the water inlet stage of S10; steps S21 to S25 belong to the water inlet confirmation stage; steps S311 to S315 belong to the water replenishment stage; steps S41 and S42 belong to the steaming and washing stage.

[0086] In the above embodiment, when the clothes processing device receives the steaming and ironing washing instruction, the control method of steaming and ironing washing is executed, that is, the water inlet valve is controlled to start water inletting, and the water inletting is stopped after the set water inlet volume is reached. In some embodiments, the water inlet valve can intermittently inlet water, for example, after inletting water for a period of time, it is closed for a period of time and then inlet water, so that the clothes can fully absorb water. Of course, in some other embodiments, the water inlet valve can also continue to inlet water until the set water inlet volume is reached. In some other embodiments, the flow rate of the water inlet valve can also be changed during the water inlet process, for example, water is inletted at a larger flow rate in the early stage of water inlet and at a smaller flow rate in the later stage of water inlet.

[0087] In the above embodiment, the first water level frequency value and the second water level frequency value are obtained by averaging values ​​collected continuously within a certain period of time, thereby improving accuracy and reliability.

[0088] like Figure 3 As shown, as an optional implementation of the above embodiment, after the motor stops rotating for a fifth preset time and the third water level frequency value in the cylinder is obtained, the method further includes:

[0089] S316, obtaining a second difference between the third water level frequency value and the second water level frequency value;

[0090] S317, if the second difference is less than a second preset difference, controlling the water inlet valve to open again;

[0091] S318, after a sixth preset time period, controlling the water inlet valve to close;

[0092] S411, controlling the clothes processing device to enter the steaming and ironing stage with the third water level frequency value as a reference water level frequency value;

[0093] S412: If the second difference is greater than a second preset difference, control the clothes processing device to enter the steaming and ironing stage using the third water level frequency value as a reference water level frequency value.

[0094] That is, in this embodiment, after water replenishment, the third water level frequency value after the drum rotates is obtained and compared with the second water level frequency value to obtain a second difference; if the second difference is less than the second preset difference, water replenishment continues within the sixth preset time length, and the third water level frequency value is used as the reference water level frequency value to enter the steaming and ironing stage; if, if the second difference is greater than the second preset difference, the third water level frequency value is directly used as the reference water level frequency value to enter the steaming and ironing stage, so that the water intake meets the steaming and ironing requirements of the clothes.

[0095] As an optional implementation of the above embodiment, the controlling the motor to rotate includes: controlling the motor to rotate forward by a preset number of revolutions or controlling the motor to rotate reversely by a preset number of revolutions or controlling the motor to rotate forward and reversely by a preset number of revolutions alternately. That is, in the embodiment, the motor can rotate counterclockwise, clockwise, or counterclockwise and clockwise alternately, so that the clothes can fully absorb water and be in an environment surrounded by steam, so that the H bonds and OH ions in the water molecules can repair the wrinkles on the clothes, and in the subsequent ironing operation of the clothes, the steam molecules and water molecules are evenly distributed in the clothes, and the clothes are evenly moist and flat after completion.

[0096] In implementation, the motor may rotate counterclockwise for one circle and then clockwise for one circle, and rotate alternately for the first preset time length or the third preset time length.

[0097] It should be noted that, in the above embodiment, if the first difference is equal to the first preset difference, or the second difference is equal to the second preset difference, a water replenishment operation may be performed, or the water replenishment operation may not be performed.

[0098] As an optional implementation of the above embodiment, Figure 4 As shown, the controlling the clothes processing device to enter the steaming and ironing stage with the third water level frequency value as the reference water level frequency value or the controlling the clothes processing device to enter the steaming and ironing stage with the second water level frequency value as the reference water level frequency value includes:

[0099] S401, control the heating device to turn on;

[0100] S402, when the temperature inside the cylinder is heated to a first preset temperature, controlling the heating device to enter a constant temperature heating state;

[0101] S403, obtaining the fourth water level frequency value in the cylinder in real time;

[0102] S404: If the difference between the fourth water level frequency value and the reference water level frequency value is greater than a third preset difference, the water inlet valve is controlled to open until the fourth water level frequency value reaches the reference water level frequency value.

[0103] In the above embodiment, the third preset difference may be 0.2 GHz.

[0104] In this embodiment, the heating device is used to heat the gas in the drum, and includes heating devices such as a heating tube or a heat exchanger. After the heating device heats the temperature in the drum to a first preset temperature, the heating device is controlled to enter a constant temperature heating state, so that the clothes are in a constant temperature environment as long as possible, which is convenient for cleaning and sterilization; because the water in the drum is consumed during the steaming and ironing stage, the fourth water level frequency value is obtained in real time, and if the difference between the fourth water level frequency value and the reference water level frequency value is greater than the third preset difference, water needs to be replenished, and the water is replenished so that the fourth water level frequency value reaches the reference water level frequency value again, so as to ensure that the water in the drum can meet the steaming and ironing requirements during the steaming and ironing stage to avoid damaging the clothes.

[0105] For example, if the reference water level frequency value is the second water level frequency value, then if the difference between the fourth water level frequency value and the second water level frequency value is greater than the third preset difference, water needs to be replenished, and the water is replenished so that the fourth water level frequency value reaches the second water level frequency value again. For another example, if the reference water level frequency value is the third water level frequency value, then if the difference between the fourth water level frequency value and the third water level frequency value is greater than the third preset difference, water needs to be replenished, and the water is replenished so that the fourth water level frequency value reaches the third water level frequency value again.

[0106] In the embodiment, if the fourth water level frequency value is equal to the reference water level frequency value, water replenishment may be performed or may not be performed.

[0107] As an optional implementation of the above embodiment, the controlling the clothing processing device to enter the steaming and ironing stage with the third water level frequency value as the reference water level frequency value or the controlling the clothing processing device to enter the steaming and ironing stage with the second water level frequency value as the reference water level frequency value also includes:

[0108] When the temperature inside the barrel is heated to a first preset temperature, the heating device is controlled to enter a constant temperature heating state. If the temperature inside the barrel is lower than a second preset temperature, the heating device is controlled to heat.

[0109] After the seventh preset time or after the temperature inside the cylinder is heated to the first preset temperature, the heating device is controlled to enter a constant temperature heating state.

[0110] Since water needs to be replenished during the steaming and scalding process, the temperature inside the drum will drop. Therefore, after the temperature inside the drum is lower than the second preset temperature, the heating device heats the drum to increase the temperature inside the drum to the first preset temperature to meet the temperature requirements of steaming and scalding.

[0111] In the above embodiment, the heating device may perform heating in an intermittent manner, for example, heating for a certain period of time and then stopping heating for another period of time to avoid damage to clothing due to excessive temperature rise.

[0112] As an optional implementation of the above embodiment, after the clothes processing device is controlled to enter the steaming and ironing stage and run for an eighth preset time, the clothes processing device is controlled to exit the steaming and ironing stage, and the drainage pump is controlled to run to drain the water in the drum. That is, in the embodiment, the steaming and ironing stage is set to a time length, and after running to the eighth preset time length, the clothes processing device exits the steaming and ironing stage, the clothes processing device enters the drainage stage, and the drainage pump drains the excess water in the drum.

[0113] In an embodiment, during the process of controlling the clothing processing device to enter the steaming and ironing stage for an eighth preset time period, the control method executes: when the temperature in the drum is heated to a first preset temperature, controlling the heating device to enter a constant temperature heating state; obtaining a fourth water level frequency value in the drum in real time; if the difference between the fourth water level frequency value and the reference water level frequency value is greater than a third preset difference, controlling the water inlet valve to open until the fourth water level frequency value reaches the reference water level frequency value, and executing when the temperature in the drum is heated to a first preset temperature, controlling the heating device to enter a constant temperature heating state, if the temperature in the drum is lower than a second preset temperature, controlling the heating device to heat; after the seventh preset time period or after the temperature in the drum is heated to the first preset temperature, controlling the heating device to enter a constant temperature heating state.

[0114] As an optional implementation of the above embodiment, after controlling the drainage pump to operate to drain the water in the drum, the control method further includes: controlling the clothing processing device to enter an ironing stage.

[0115] That is, after the drainage is completed, the clothes processing device enters the ironing stage, at which time the drum can be rotated at a preset speed so that water molecules and steam molecules can smooth out the wrinkles on the clothes. After running for a certain period of time, the clothes processing device stops running and sends an indication to the user that the washing is completed, such as sending a prompt message to the user's APP or emitting voice, music, etc.

[0116] In the above embodiments, the certain time period, the preset time period, the preset temperature, and the preset difference are set by the user or factory settings, and will not be described in detail again.

[0117] Compared with the prior art, the technical solution of the present application has the following characteristics and advantages: the water content of the load is accurately controlled through water inlet control and water inlet confirmation control, and the minimum water consumption of the heating tube is guaranteed; the temperature of the water with less heating rises quickly and quickly reaches the high-temperature steam state, and the high-temperature steam control allows the steam to be continuously generated. After the clothes are fully steamed, they are smoothed and evenly wetted through centrifugal rotation to achieve the effect of sterilization and wrinkle removal. Among them,

[0118] After the water is inletted, the water inlet confirmation stage is used to make up for the accuracy deviation of the water level detection to ensure the accuracy of the water inlet and meet the water volume requirements for steaming and ironing clothes. Specifically, the water inlet is further judged by the difference in the water level frequency value before and after the drum rotates. If the conditions are met, the steaming and ironing stage is entered. If not, the water continues to be inletted to further accurately control the water volume. Through heating control and temperature rise control, intermittent heating can be used to avoid the high temperature of the heating tube due to low water volume, which affects the life of the heating tube. At the same time, it is avoided that the clothes are heated up too quickly, which affects the changes in material properties, especially the deformation of the fabric. Through steam constant temperature control, the continuous steam generation is guaranteed, and the steam surrounding the clothes is guaranteed to be sufficient. The H bonds and OH ions of water molecules repair wrinkled clothes. Entering the ironing stage, the drum rotates so that the steam molecules and water molecules are evenly distributed in the clothes. After completion, the clothes are evenly moist and flat.

[0119] like Figure 5 As shown, the present application also proposes a control device for steaming and ironing, the control device comprising:

[0120] The control module 10 is used to control the water inlet valve to close when the water inlet volume reaches a set water inlet volume;

[0121] An acquisition module 20 is used to acquire a first water level frequency value in the cylinder;

[0122] The control module 10 is also configured to: control the motor to rotate; the motor is used to drive the drum of the laundry processing device; after a first preset time, control the motor to stop rotating;

[0123] The acquisition module 20 is further configured to: acquire a second water level frequency value in the cylinder after a second preset time; acquire a first difference between the first water level frequency value and the second water level frequency value;

[0124] The control module 10 is further configured to control the water inlet valve to open if the first difference is less than the first preset difference; control the water inlet valve to close after a third preset time; control the motor to rotate again; and control the motor to stop rotating after a fourth preset time.
