[0010] In the specific implementation of the control method of the above washing device, during the process of "opening the water inlet valve and closing the drain valve, and at the same time the drum rotates at a third preset speed", the water inlet valve is controlled according to the water level in the drum.

[0011] In the specific implementation of the control method of the above washing device, "controlling the water inlet valve according to the water level in the drum" includes: if the water level in the drum is higher than the first preset water level, closing the water inlet valve; and / or, if the water level in the drum is not higher than the first preset water level, the water inlet valve remains open.

[0012] In the specific implementation of the control method of the above washing device, after "opening the water inlet valve and closing the drain valve, and at the same time the drum rotates at a third preset speed", the water inlet valve is closed, the drain valve is opened, and the drum rotates at a fourth preset speed for dehydration.

[0013] In the specific implementation of the control method of the above washing device, after "closing the water inlet valve and opening the drain valve", it is determined whether to rotate the drum according to the change in the water level frequency of the washing device.

[0014] In the specific implementation of the control method of the above washing device, "determining whether to rotate the drum according to the change in the water level frequency in the drum" includes: if the change in the water level frequency of the washing device is lower than the preset value, rotating the drum for dehydration; and / or, if the change in the water level frequency in the drum is not lower than the preset value, the drum remains in a stopped state.

[0015] In the specific implementation of the control method of the above washing device, the washing device further includes a drum, and the control method of the washing device further includes: obtaining the amount of foam in the drum; determining whether to "open the water inlet valve and the drain valve simultaneously" according to the amount of foam.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0039] In addition, it should also be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "setting", "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and can also be the communication inside two elements. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0040] In order to solve the problem that the washing time is too long when removing foam in the existing washing device, the present invention provides a control method for a washing device and a washing device.

[0041] The washing device includes a drum, a water inlet pipe and a drain pipe. The water inlet pipe is provided with a water inlet valve, and the drain pipe is provided with a drain valve. After the water inlet valve is opened, the water inlet pipe can add tap water into the drum. After the drain valve is opened, the drain pipe can drain the water in the drum.

[0042] Generally speaking, an outer cylinder is provided outside the rotary drum, and the outer cylinder is fixedly connected to the housing of the washing device. The rotary drum can rotate relative to the outer cylinder. It should be noted that the washing device involved in the present invention is applicable to both drum washing devices and agitator washing devices, and the items to be cleaned include but are not limited to clothes and shoes. For a drum washing device, the inner cylinder can be used for washing, rinsing or dehydration. For an agitator washing device, it also includes an agitator. After the agitator rotates, it can agitate the clothes for washing and rinsing. At this time, the inner cylinder is mainly used for dehydration.

[0043] The washing device further includes a control module, and the control module is configured to execute the control method of the washing device.

[0044] As Figure 1 shown, the control method of the washing device provided by the present invention includes:

[0045] Open the water inlet valve and the drain valve simultaneously. At this time, water can continuously flow from the water inlet pipe to the clothes located in the rotary drum, rinse the clothes, wash away the foam on the surface of the clothes, and the water flow carrying a large amount of foam can directly drain from the drain pipe, achieving the purpose of quickly eliminating foam.

[0046] In some examples, while "opening the water inlet valve and the drain valve simultaneously", the rotary drum rotates at a first preset speed to agitate the clothes. The rotary drum rotates at the first preset speed, which can agitate the clothes, improve the contact effect between the water flow and the clothes, thereby improving the rinsing effect of the water flow on the foam attached to the surface of the clothes and shortening the time for removing foam. For example, the first preset speed is 300 RPM (Revolutions Per Minute). It should be noted that for an agitator washing device, the agitator rotates at the first preset speed.

[0047] In some examples, before "opening the water inlet valve and the drain valve simultaneously", the water inlet valve is closed and the drain valve is opened, and the rotary drum rotates at a second preset speed for dehydration, where the second preset speed is greater than the first preset speed, such as 450 RPM. Dehydrating the clothes before opening the water inlet valve and the drain valve to eliminate foam can reduce the moisture and foam content in the clothes, so that the effect of opening the water inlet valve and the drain valve to eliminate foam is better, and the washing time and water consumption for eliminating foam are less.

[0048] The dehydration is divided into two stages. In the first stage, the rotary drum stops, and first the water in the outer cylinder is drained; in the second stage, the rotary drum rotates at the second preset speed to spin-dry the clothes. The method for determining whether the first stage of dehydration ends to start the rotary drum for rotational dehydration includes:

[0049] Determine whether to rotate the drum according to the change in the water level frequency inside the washing device. Specifically, it includes: if the change in the water level frequency of the washing device is lower than the preset value, it indicates that the water in the drum has been basically drained, and the drum is rotated to drain the water in the clothes; if the change in the water level frequency of the washing device is not lower than the preset value, it indicates that the water in the drum has not been completely drained, and the drum remains stationary. Among them, the frequency-type water level sensor can detect the frequency of the water inside the washing device, obtain the water level according to the frequency of the water, and the change in the water level frequency is the change amount of the water level frequency per unit time, which is the change in the water level frequency within 5S in this example.

[0050] In some examples, after "opening the water inlet valve and the drain valve simultaneously", the water inlet valve is opened and the drain valve is closed, and the drum rotates at a third preset speed. At this time, when the water inlet valve is opened and the drain valve is closed, the water level inside the drum will gradually rise, and the drum drives the clothes to rotate for rinsing. At the same time, the drum can also stir the water flow, so that the water flow impacts and washes the inner surface of the outer drum, washing away the foam attached to the inner surface of the outer drum, so as to prevent the foam attached to the inner surface of the outer drum from dripping into the inner drum and contaminating the washed clothes during other washing processes. Among them, the third preset speed is greater than the first preset speed, for example, 450 RPM. It should be noted that for the pulsator washing device, the pulsator rotates at the third preset speed.

[0051] During the process of the drum rotating at the third preset speed to impact and wash the outer drum, the water level inside the drum should not be too high, otherwise the resistance of the water flow stirred after the drum rotates increases, the water flow velocity decreases, the impact force generated by the water flow decreases, and the effect of impacting and washing the outer drum will decrease. Therefore, during this process, it is necessary to keep the water level inside the drum below the preset water level. Specifically, it includes:

[0052] Control the water inlet valve according to the water level inside the drum. Specifically, it includes: if the water level inside the drum is higher than the preset water level, it indicates that the water level inside the drum is slightly high, and the water inlet valve is closed. Stop injecting water into the drum; if the water level inside the drum is not higher than the preset water level, it indicates that the water level inside the drum has not reached the preset water level, and the water inlet valve remains open, continuously injecting water into the drum to avoid affecting the washing of the clothes. In the example of the present invention, the preset water level is one-half of the drum height.

[0053] In some examples, after the clothes are washed and the outer drum is impacted and washed, the water inlet valve is closed and the drain valve is opened, and the drum rotates at a fourth preset speed for dehydration. For example, the fourth preset speed is 450 RPM. Among them, the dehydration is also divided into two stages. In the first stage, the drum stops, and the water in the outer drum is first drained; in the second stage, the drum rotates at the second preset speed to drain the water from the clothes.

[0054] A method for determining whether the first stage of dehydration is completed to start the drum for rotational dehydration includes: determining whether to rotate the drum according to the change in the water level frequency in the washing device. Specifically, if the change in the water level frequency of the washing device is lower than a preset value, it indicates that the water in the drum has been basically drained, and the drum is rotated to drain the water in the clothes; if the change in the water level frequency of the washing device is not lower than the preset value, it indicates that the water in the drum has not been completely drained, and the drum remains stationary. Among them, the change in the water level frequency is the amount of change in the water level at the bottom of the outer drum per unit time.

[0055] In some examples, the above control method is built into the washing device and performs corresponding washing processes according to the washing program selected by the user. For example, if the user selects the defoaming mode, the above control method is executed.

[0056] Of course, in some examples, the control method of the washing device further includes: obtaining the amount of foam in the drum and determining whether to "simultaneously open the water inlet valve and the drain valve" according to the amount of foam, that is, whether to enter the defoaming mode. Specifically, if the amount of foam is greater than the preset amount, it indicates that the conventional washing mode is not the optimal washing solution, which may cause waste of water resources or incomplete cleaning. Therefore, the water inlet valve and the drain valve are simultaneously opened to enter the defoaming mode; if the amount of foam is not greater than the preset amount, the defoaming mode is not entered, and the conventional washing mode is executed.

[0057] In summary, as Figure 2 shown, the specific steps of the control method of the washing device provided by the present invention include:

[0058] S1. Obtain the amount of foam in the washing device. This step is usually carried out after the washing stage is completed.

[0059] S2. Judge whether the amount of foam is greater than the preset amount. If the amount of foam is greater than the preset amount, it indicates that the current washing program may be difficult to completely eliminate the foam, resulting in incomplete washing. At this time, execute step S3 to enter the defoaming mode; if the amount of foam is not greater than the preset amount, execute step S21.

[0060] S21. Execute the current washing program.

[0061] S3. Close the water inlet valve and open the drain valve to drain the water in the washing device.

[0062] S31. Obtain the change in the water level frequency within 5S.

[0063] S32. Judge whether the change in the water level frequency is lower than the preset value. If the change in the water level frequency is lower than the preset value, it indicates that the water in the washing device has been basically drained, and execute step S33; if the change in the water level frequency is not lower than the preset value, it indicates that the water in the washing device has not been drained completely, and continue to execute step S32 after an interval of time.

[0064] S33: Rotate the drum at a second preset speed to dehydrate the clothes. This step lasts for a first preset time, and then proceeds to step S4.

[0065] S4. Open the water inlet valve and the drain valve, while the drum rotates at a first preset speed to agitate the clothes. This step continues for a second preset time, after which step S5 is executed. During this step, water continuously flows from the water inlet pipe to the clothes in the drum, rinsing the clothes and removing foam from the surface of the clothes. The water, carrying a large amount of foam, is then discharged directly from the drain pipe, achieving the purpose of quickly eliminating foam. Simultaneously, the drum rotates at the first preset speed, agitating the clothes and improving the contact between the water and the clothes, thereby improving the water's effectiveness in rinsing foam adhering to the clothing surface and shortening the time required to remove foam.

[0066] S5. Close the water inlet valve and open the drain valve to drain the water in the drum.

[0067] S51. Obtain the water level frequency change within 5 seconds.

[0068] S52: Determine whether the water level frequency change is lower than a preset value. If the water level frequency change is lower than the preset value, it indicates that the water in the washing machine has been substantially drained, and the process proceeds to step S6. If the water level frequency change is not lower than the preset value, it indicates that the water in the washing machine has not been completely drained, and the process proceeds to step S52 after a period of time.

[0069] S6. Open the water inlet valve and close the drain valve, and the drum rotates at a third preset speed. The water level in the drum gradually rises, driving the laundry to rotate and wash. Simultaneously, the drum agitates the water, causing it to impact the inner surface of the outer drum and rinse away any foam adhering to it, preventing it from dripping into the inner drum and contaminating the washed laundry. During step S6, step S61 is executed.

[0070] S61. Obtain the water level in the drum.

[0071] S62: Determine whether the water level in the drum is higher than a preset water level. If the water level in the drum is higher than the preset water level, it indicates that the water level in the drum is slightly high, and the process proceeds to step S63. If the water level in the drum is not higher than the preset water level, it indicates that the water level in the drum has not reached the preset water level, and the process proceeds to step S6.

[0072] S63: Close the water inlet valve and the drain valve, and the drum rotates at a third preset speed. The sum of the durations of step S6 and step S63 is the third preset time.

[0073] S7. Close the water inlet valve and open the drain valve to drain the water in the drum.

[0074] S71. Obtain the water level frequency change within 5S.

[0075] S72. Determine whether the water level frequency change is lower than the preset value. If the water level frequency change is lower than the preset value, it indicates that the water in the washing device has been basically drained, and step S8 is executed; if the water level frequency change is not lower than the preset value, it indicates that the water in the washing device has not been drained completely, and step S72 is continued after a certain period of time.

[0076] S8. Rotate the drum at the fourth preset speed for dehydration. This step lasts for the fourth preset time, and then the program ends.

[0077] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
