The washing equipment includes a dewatering program for dewatering clothes in the tub.

[0043] The dewatering control method of the washing equipment in the present application includes: when the dewatering program is executed, the air inlet into the tub along the inner peripheral side wall of the tub can be controlled.

[0049] The step S2 of determining whether the air intake is needed in the application includes:

[0050] According to the amount of clothes in the barrel, it is determined whether the air intake is needed, if the amount of clothes is large, the air intake into the barrel is controlled; or, according to whether the clothes in the barrel are stacked, it is determined whether the air intake is needed, if the clothes are stacked, the air intake into the barrel is controlled; or, according to whether the air intake instruction of the user is received, it is determined whether the air intake is needed, if the air intake instruction is received, the air intake into the barrel is controlled.

[0051] Further specifically, in the application, the step S4 includes:

[0052] S41, presetting a total dehydration time;

[0053] S42, accumulating the dehydration time;

[0054] S43, comparing the accumulated dehydration time with the preset total dehydration time;

[0055] S44, if the accumulated dehydration time is greater than or equal to the preset total dehydration time, it is determined that the dehydration is completed; otherwise, it is determined that the dehydration is not completed.

[0056] In the application, by the air intake into the barrel along the inner circumferential side wall of the barrel, the clothes close to the inner circumferential side wall of the barrel can be separated from the inner circumferential side wall under the blowing action of the air, thereby avoiding the clothes stacking on the inner circumferential side wall of the barrel, so that the clothes can change position more easily in the dehydration process, thereby uniform dehydration, and avoiding the phenomenon of local uneven dehydration of the clothes.

[0064] As another embodiment of the present application, the control of the air introduction into the drum includes: controlling the air to be intermittently introduced into the drum. Further, the total dehydration time of the dehydration program is obtained, and the air introduction frequency of the intermittent air introduction is in a positive correlation with the total dehydration time.

[0065] In this embodiment, the longer the total dehydration time is, the more serious the clothes stacking in the drum is, and at this time, the corresponding air introduction frequency is controlled to be increased, so that the position of the clothes in the dehydration process can be timely and effectively adjusted, and the clothes tightly stacked together in the long-time dehydration rotation process is avoided, so that the dehydration effect of the stacked position is poor.

[0066] As still another embodiment of the present application, when the dehydration program is executed, it is judged whether the clothes in the drum are stacked, if yes, the air is controlled to be introduced into the drum, otherwise, the air is not controlled to be introduced into the drum.

[0080] In the embodiment, the camera is arranged on the washing device and is electrically connected or communicatively connected with the control system of the washing device, and is used to acquire the image in the barrel.

[0081] In the embodiment, if the position information of the clothes changes compared with the image acquired last time, it indicates that the clothes are not stacked and the position of the clothes is adjusted during the dehydration process, and air is not required to enter the barrel at this time, so as to reduce the waste of energy.

[0082] On the contrary, if the position information of the clothes does not change, it indicates that the clothes are stacked and the position of the clothes basically does not change during the dehydration process, and air is controlled to enter the barrel at this time, so as to adjust the position of the stacked clothes and make the clothes be fully dehydrated in the subsequent dehydration process.

[0083] As another embodiment of the embodiment, the control of air to enter the barrel includes: if the clothes are stacked, the position of the stacked clothes is locked, and air is controlled to enter the locked position.

[0085] S2, preset the time t0;

[0086] S3, acquire the image P1 in the barrel;

[0087] S4, acquire the image P2 in the barrel again after the interval time t0;

[0088] S5, compare the image P2 with the image P1, judge whether the position information of the clothes in the image P2 changes; if yes, execute step S6; otherwise, start to execute step S9; wherein the position information of the clothes includes: the position of the clothes in the barrel and the relative position relationship between the clothes and other clothes;

[0089] S6, judge that the clothes in the barrel are stacked;

[0091] S8, control the air inlet to the locked stacking position along the inner circumferential side wall of the barrel;

[0092] S9, judge whether the dehydration is completed, if yes, execute step S10; otherwise, return to step S1;

[0093] S10, the dehydration is completed.

[0094] In this embodiment, the air inlet to the stacked position of the clothes is controlled, which can be specially adjusted for the stacking position, can avoid the stacking of the clothes, and can fully and reasonably utilize the air inlet to avoid the waste of the air inlet.

[0095] As another embodiment of the application, during the control of the air inlet, it is judged whether the position of the locked stacked clothes changes, if yes, the air inlet is controlled to end.

[0096] Specifically, as shown in Figure 5 , the control step includes:

[0097] S1, dehydration;

[0098] S2, preset time t0;

[0099] S3, acquire the image P1 in the barrel;

[0100] S4, acquire the image P2 in the barrel again after the interval time t0;

[0101] S5, compare the image P2 with the image P1, judge whether the position information of the clothes in the image P2 changes; if yes, execute step S6; otherwise, start to execute step S11; wherein the position information of the clothes includes: the position of the clothes in the barrel and the relative position relationship between the clothes and other clothes;

[0102] S6, judge that the clothes in the barrel are stacked;

[0103] S7, control the position of the locked clothes stack; in particular, mark the coordinates of the position of the clothes stack, for example, mark the horizontal and vertical coordinates of the position of the clothes stack with the inner circumferential wall of the barrel as the coordinate system;

[0104] S8, control air inlet to the locked stack position along the inner circumferential wall of the barrel;

[0105] S9, determine whether the position of the locked clothes stack changes; if yes, execute step S10; otherwise, return to step S8;

[0106] S10, control air inlet to end

[0107] S11, determine whether the dehydration is completed, if yes, execute step S12; otherwise, return to step S1;

[0108] S12, dehydration ends.

[0109] In particular, in the embodiment, step S9 includes:

[0110] S91, before starting air inlet, mark the horizontal and vertical coordinates of the position of the clothes stack with the inner circumferential wall of the barrel as the coordinate system;

[0111] S92, during air inlet, recapture the horizontal and vertical coordinates of the clothes stack;

[0112] S93, compare whether the recaptured horizontal and vertical coordinates are the same as the horizontal and vertical coordinates before starting air inlet; if yes, determine that the position of the locked clothes stack does not change; otherwise, determine that the position of the clothes stack changes.

[0113] In the embodiment, when it is determined that the position of the clothes stack changes, it indicates that the position of the clothes has been successfully adjusted, at which time the air inlet is controlled to end, avoiding energy waste caused by continuous air inlet. The embodiment can reasonably control the length of time of air inlet according to the specific situation of the clothes stack during air inlet, which not only ensures good dehydration effect of the clothes, but also avoids energy waste.

[0114] As an embodiment of the embodiment, controlling air inlet to the locked stack position includes: obtaining the amount of clothes stacked at the locked stack position, and controlling the air inlet amount to be in a positive correlation with the obtained amount of clothes.

[0115] In particular, obtaining the amount of clothes stacked at the locked stack position includes: obtaining an image of the stack position, and obtaining the amount of clothes according to the obtained image. Alternatively, the circumferential wall of the barrel is provided with a pressure sensor, and the pressure value of the circumferential wall of the barrel at the stack position is obtained. The greater the pressure value, the more the amount of clothes stacked at the stack position.

[0116] In this embodiment, the more clothes stacked at the stacking position, the more difficult it is to adjust the position of the clothes, and thus the air inlet is controlled to be larger, so that the position of the stacked clothes can be adjusted in a shorter time. Conversely, when the amount of clothes stacked at the stacking position is small, it indicates that the difficulty of adjusting the position of the clothes is also small, and thus the air inlet is controlled to be small, so that the purpose of adjusting the position of the clothes can be achieved, and energy waste can be avoided.

[0117] As another embodiment of the present application, the dewatering program includes a rotation phase of controlling the rotation of the barrel and a pause phase of controlling the pause of the barrel, and air is introduced into the barrel in the pause phase. Further specifically, the bottom of the barrel is provided with an impeller structure, and the rotation of the impeller is controlled when air is introduced.

[0118] In this embodiment, air is introduced into the barrel in the pause phase, avoiding the influence of the centrifugal force on the clothes during the rotation of the barrel, so that the position adjustment effect of the air on the clothes is better. Further, the impeller structure is controlled to rotate during the air introduction process, so that the clothes can be moved to a new position, and the efficiency of adjusting the position of the clothes is improved by cooperating with the air introduction program.

[0119] In addition, when the user forgets to dry the clothes after completing the washing of the clothes, the hot air is introduced by the program control, so that the clothes can be dried. The introduction of the hot air can also sterilize the inner circumferential wall of the barrel and the clothes in the barrel at high temperature.

[0120] The present application also provides a washing device controlled by the dewatering control method.

[0121] The washing device of the present application is controlled by the control method of the present application, and the washing device of the present application can adjust the position of the clothes in the barrel during the dewatering process, so that the clothes can be uniformly dewatered, and the user experience is improved.

[0122] As an embodiment of the present application, as shown in Figure 6 to Figure 8 The washing device includes a barrel for accommodating clothes, and an air inlet 2 is arranged on the barrel mouth side along the circumferential direction of the barrel mouth for introducing air into the barrel. Specifically, the washing device includes a balance ring structure 1 arranged above the barrel mouth, the balance ring structure 1 is provided with an air inlet duct 3 arranged along the circumferential direction of the balance ring structure, and the air inlet 2 is arranged on the air inlet duct 3.

[0123] Preferably, the balance ring structure 1 includes a lower end face arranged towards the barrel mouth, and the air inlet duct 3 is integrated on the lower end face of the balance ring structure 1. The air inlet duct 3 is integrated on the balance ring structure 1, and can be disassembled and installed together with the balance ring structure 1.

[0124] Further, the washing device further comprises a fan, an air outlet end of the fan being communicated with the air inlet 31 of the air inlet duct 3. The fan blows air into the air inlet duct 3 through the air inlet 31, and the air in the air inlet duct 3 enters the tub through the air inlet 2.

[0125] In the embodiment, the air inlet duct 3 is integrated on the balance ring structure 1, and the air inlet 2 on the air inlet duct 3 is communicated with the inside of the tub, so that air can be blown into the tub. The installation structure is simple, and the clothes attached to the inner circumferential wall of the tub can be effectively peeled off from the inner circumferential wall.

[0126] The above is only the preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with the preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above-mentioned technical content without departing from the technical solution of the present application, and any simple modification, equivalent change and modification of the above-mentioned embodiment according to the technical essence of the present application still belong to the scope of the present application.
