[0002] With the advancement of technology, washing machines, sock washing machines, shoe washing machines, and the like have gradually entered users' homes. In order to improve the washing effect, when washing clothes using the washing machine, detergent needs to be added to the washing drum of the washing machine, for example, the user manually adds detergent or uses a detergent dispensing device of the washing machine itself to dispense detergent.

[0003] However, the detergent does not fully dissolve every time the clothes are washed. In the case where the detergent is not completely dissolved, for example, the added washing powder settles to the bottom of the washing drum, the washing powder cannot be fully utilized, thereby lengthening the washing time to achieve the cleaning effect, or the original washing time remains unchanged, resulting in a deterioration in the washing effect.

[0021] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

[0022] In order to solve the problem that detergent cannot be fully dissolved when washing clothes in existing washing equipment, the present invention provides a control method for a washing equipment, wherein the washing equipment can be a washing machine, a sock washing machine, a shoe washing machine, etc. For the sake of convenience, the washing equipment of the present invention will be introduced below by taking a drum washing machine as an example.

[0023] The outer drum of the drum washing machine is provided with a drain port, and the inner drum is coaxially rotatably arranged in the outer drum. The drain pump of the drum washing machine of the present invention is arranged at a position lower than the drain port. For example, the drum washing machine is an upper drainage drum washing machine, that is, the drain port is connected to the inlet of the drain pump through the first drain pipe, and the outlet of the drain pump is connected to the second drain pipe. At least part of the pipe section of the second drain pipe is higher than the drain port, such as the water outlet end of the second drain pipe is higher than the drain port. Preferably, the drain pump is located at the lowest point of the drainage waterway so that part of the water can be stored in the drain pump after the drum washing machine finishes draining. It can be understood that when the drain pump drains water, the drain pump rotates forward so that the washing water in the outer drum is discharged from the drain port-the first drain pipe-the second drain pipe.

[0024] As a possible implementation, the drum washing machine of the present invention further includes a turbidity sensor, which is used to detect the turbidity value at the bottom of the inner drum or the outer drum. For example, the turbidity sensor is installed at the bottom of the outer drum.

[0025] like Figure 1 As shown, the control method of the drum washing machine of the present invention is introduced below. The control method of the drum washing machine of the present invention comprises the following steps:

[0026] Step S100: During or after the water inlet stage, the inner drum of the drum washing machine is controlled to rotate.

[0027] When washing clothes with a drum washing machine, a washing program is first selected and activated. After the washing program is activated, a water inlet stage is performed, during which water is injected into the inner and outer drums. After water is injected into the inner and outer drums, such as after a preset water level is injected, or after the water inlet stage is completed, the inner drum is controlled to rotate.

[0028] Step S200: After the inner drum rotates for a preset time, the drainage pump is controlled to rotate in reverse.

[0029] Due to the rotation of the inner drum, the mixture of clothes and water is stirred. After the inner drum rotates for a preset time, detergents such as washing powder can be precipitated to the bottom of the inner drum and the outer drum. At this time, the drainage pump is controlled to reverse, and the impeller of the drainage pump will stir the water flow at the bottom of the inner drum and the outer drum, thereby stirring the detergents precipitated at the bottom of the inner drum and the outer drum. Therefore, the precipitated detergents are fully dissolved and foam can be generated. The detergents are re-flowed into the inner drum to participate in washing clothes, thereby improving the washing effect. Since the detergents are fully utilized, the washing time is shortened, energy consumption is saved, and the energy efficiency level of the washing machine is improved.

[0030] The preset time mentioned above is the time that allows the detergent to settle to the bottom of the inner drum and the outer drum. The preset time can be determined based on experience or experiments, and the present invention does not limit the method of determining it.

[0031] Furthermore, after the inner drum rotates for a preset time, it is determined whether the detergent in the inner drum reaches a preset dissolution condition. If not, the drain pump is controlled to reverse.

[0032] That is to say, after the inner drum rotates for a preset time, it is determined whether the detergent in the inner drum has reached the preset dissolution condition. If the detergent in the inner drum has not reached the preset dissolution condition, that is, the detergent has not been fully dissolved, the detergent will sink to the bottom of the inner drum and the outer drum. In this case, the drainage pump is controlled to reverse so that the detergent is fully dissolved. If the detergent has reached the preset dissolution condition, that is, the detergent is fully dissolved, the detergent will not accumulate at the bottom of the inner drum and the outer drum. In this case, the drainage pump can be stopped to avoid wasting energy and save energy consumption of the washing machine.

[0033] Among them, there are many possible implementation methods for judging whether the detergent in the inner drum has reached the preset dissolution condition, and the following two embodiments will be introduced as examples.

[0034] Embodiment 1:

[0035] Determine whether the amount of foam in the inner cylinder is greater than a preset amount of foam.

[0036] That is, when the amount of foam in the inner drum is greater than the preset amount of foam, it proves that the detergent in the inner drum is fully dissolved and the detergent will not sink to the bottom of the inner drum and the outer drum. In this case, the drain pump can be controlled to stop rotating. When the amount of foam in the inner drum is less than or equal to the preset amount of foam, it proves that the detergent in the inner drum is not fully dissolved and the detergent has sunk to the bottom of the inner drum and the outer drum. At this time, the drain pump is controlled to reverse so that the detergent can be fully dissolved.

[0037] There are many methods for determining whether the amount of foam in the inner cylinder is greater than a preset amount of foam.

[0038] As a possible implementation, step S100 is further "controlling the rotation of the inner drum after the water inlet stage is over". Under the premise of step S100, after the water inlet stage is over, the first water level is obtained, and after the inner drum rotates for a preset time, the second water level is obtained, and the amount of foam in the inner drum is determined based on the difference between the second water level and the first water level.

[0039] Among them, a water level sensor can be installed on the outer drum to monitor the water level of the washing drum. After the water inlet stage is over, that is, after the first water inlet is over, the first water level is obtained. After the inner drum rotates for a preset time, at least part of the detergent will be dissolved, thereby generating foam. The foam floats on the water surface, causing the water level to rise. The water level obtained at this time is the second water level. The second water level is usually higher than the first water level, so the amount of foam in the inner drum is determined based on the difference between the second water level and the first water level. For example, a mapping relationship between the water level difference and the amount of foam is pre-stored in the drum washing machine. After determining the water level difference, the amount of foam can be obtained. Or the amount of foam can be determined by a formula. Since the volume of the inner drum is determined and its radius is also determined, the water level difference is used as a height value. Therefore, the foam volume can be obtained by the cylinder volume formula. The foam volume is the foam amount, which is equal to π×the square of the inner drum radius×the water level difference.

[0040] As another possible implementation, an image acquisition device is installed in the washing device, for example, the image acquisition device is a camera or a camera, etc., which can be set on a door body or the like, for acquiring an image in the inner drum. The control method of the present invention also includes: after the inner drum rotates for a preset time, acquiring an image in the inner drum, and determining the amount of foam in the inner drum based on the image.

[0041] The neural network model can be pre-trained, the image is used as the input end of the neural network model, and the foam amount is used as the output end of the neural network model. Therefore, the foam amount in the inner cylinder can be determined by inputting the image acquired by the image acquisition device.

[0042] As a possible implementation, the washing device of the present invention pre-stores a first correspondence between a washing program, a detergent dosage, and a foam amount. For example, the first correspondence exists in the form of a mapping table, or in the form of other mapping relationships. For example, if the washing program is large-piece washing, when the large-piece washing program is run, 10 ml of detergent is added, and the amount of foam generated is a; when the standard washing program is run, 8 to 10 ml of detergent is added, and the amount of foam generated is b, and when 4 to 6 ml of detergent is added, the amount of foam generated is c. Then the information of the first correspondence "washing program-detergent dosage-foam amount" includes: large-piece washing program-10 ml-a, standard washing program-8 to 10 ml-b, standard washing program-4 to 6 ml-c.

[0043] The preset foam amount of the present invention may be determined based on the following method.

[0044] When the washing device is activated, the current washing program and the current detergent usage are obtained, and based on the first corresponding relationship, the foam amount corresponding to the current washing program and the current detergent usage is determined as the preset foam amount.

[0045] When the washing device is enabled, the user will select a washing program through the control interface of the washing device, or select a washing program through the control terminal and send it to the washing device, or send the washing program to the washing device in other ways, and then the washing device will receive the washing program for this washing, that is, the current washing program, and then the washing device will run based on the washing program and start the water intake stage. Among them, the control terminal can be a remote control, or an APP set on a mobile terminal such as a mobile phone, a tablet computer, or a computer. When the washing device runs based on the program, if the washing device is provided with a detergent quantitative delivery box, the outlet of the detergent quantitative delivery box can be provided with a flow meter, and the washing device can obtain the amount of detergent delivered in this washing program, that is, the current detergent amount, through the flow meter; or the user directly inputs the detergent amount for this washing, so that the washing device directly obtains the current detergent amount. After the washing device obtains the current washing program and the current detergent amount, it can determine the foam amount corresponding to the current washing program and the current detergent amount based on the first corresponding relationship, and determine the foam amount as the preset foam amount. If the washing program this time is standard washing and the amount of detergent used is 5 ml, the preset foam amount is c.

[0046] The above control method can determine, based on the first corresponding relationship, that the amount of foam corresponding to the previous washing program and the current amount of detergent used is the preset amount of foam, thereby being able to obtain a more accurate preset amount of foam, and then being able to accurately judge whether the drain pump needs to be reversed, thereby being able to achieve energy-saving effects while ensuring that the detergent is fully dissolved.

[0047] Embodiment 2:

[0048] The washing device also includes a turbidity sensor, which is used to detect the turbidity value at the bottom of the washing tub.

[0049] After the inner drum is controlled to rotate for a preset time, the turbidity value detected by the turbidity sensor is obtained. The step of "determining whether the detergent in the washing drum reaches the preset dissolution condition" further includes: determining whether the turbidity value is less than the preset turbidity value.

[0050] That is, when the turbidity value is less than the preset turbidity value, it proves that the detergent concentration at the bottom is low, the detergent has been fully dissolved in the water, and the detergent has reached the preset dissolution condition. At this time, there is no need to control the drainage pump to reverse, and it can continue to be in the stopped operation. When the turbidity value is greater than or equal to the preset turbidity value, it proves that the detergent concentration at the bottom is high and the detergent is not fully dissolved in the water. At this time, the drainage pump is controlled to reverse so that the detergent can be fully dissolved.

[0051] The preset turbidity value of the present invention may be determined based on the following method.

[0052] The washing equipment has pre-stored a second correspondence between washing programs, detergent dosage and turbidity value. For example, the second correspondence exists in the form of a mapping table, or in the form of other mapping relationships. If the washing program is large-piece washing, when the large-piece washing program is running, 10 ml of detergent is added, and the turbidity value is M; when the standard washing program is running, 8 to 10 ml of detergent is added, the turbidity value is N, and when 4 to 6 ml of detergent is added, the turbidity value is Q. Then the information of the second correspondence "washing program-detergent dosage-turbidity value" includes: large-piece washing program-10 ml-M, standard washing program-8 to 10 ml-N, standard washing program-4 to 6 ml-Q.

[0053] The preset turbidity value of the present invention may be determined based on the following method.

[0054] When the washing device is activated, the current washing program and the current detergent usage are obtained, and based on the second corresponding relationship, the turbidity value corresponding to the current washing program and the current detergent usage is determined to be a preset turbidity value.

[0055] When the washing device is enabled, the user will select a washing program through the control interface of the washing device, or select a washing program through the control terminal and send it to the washing device, or send the washing program to the washing device in other ways, and then the washing device will receive the washing program for this washing, that is, the current washing program, and then the washing device will run based on the washing program and start the water intake stage. Among them, the control terminal can be a remote control, or an APP set on a mobile terminal such as a mobile phone, a tablet computer, or a computer. When the washing device runs based on the program, if the washing device is provided with a detergent quantitative delivery box, the outlet of the detergent quantitative delivery box can be provided with a flow meter, and the washing device can obtain the amount of detergent delivered in this washing program, that is, the current detergent amount, through the flow meter; or the user directly inputs the detergent amount for this washing, so that the washing device directly obtains the current detergent amount. After the washing device obtains the current washing program and the current detergent amount, it can determine the turbidity value corresponding to the current washing program and the current detergent amount based on the second corresponding relationship, and determine the turbidity value as the preset turbidity value. If the washing procedure is standard washing and the amount of detergent is 5 ml, the preset turbidity value is Q.

[0056] The above control method can determine, based on the second corresponding relationship, that the turbidity value corresponding to the previous washing program and the current detergent usage is the preset turbidity value, thereby being able to obtain a more accurate preset turbidity value, and then being able to accurately judge whether the drain pump needs to be reversed, thereby being able to achieve energy-saving effects while ensuring that the detergent is fully dissolved.

[0057] It is understandable that the two control methods of the above-mentioned embodiment 1 and embodiment 2 can be used alone or in combination, that is, the drainage pump is controlled to reverse only when the foam amount is less than or equal to the preset foam amount and the turbidity value is greater than or equal to the preset turbidity value. On the basis of ensuring that the detergent is fully dissolved, the washing device can be more energy-efficient.

[0058] As a possible implementation, the step of "controlling the drain pump to reverse" in step S200 further includes: "controlling the drain pump to reverse intermittently". For example, the drain pump is controlled to reverse once every preset time, and the reversal lasts for a certain time, such as controlling the drain pump to reverse once every 10 seconds, and the reversal duration is 5 seconds, etc. Those skilled in the art can reasonably set the reversal duration and preset time based on experiments or experience. Since the drain pump is controlled to reverse intermittently, energy saving and consumption reduction can be achieved, and washing energy efficiency can be improved.

[0059] After the washing program is finished, the drain pump is controlled to rotate forward to drain the water.

[0060] like Figure 2 As shown, as a first possible implementation, the control method of the washing device of the present invention includes the following steps:

[0061] Step S301: Execute a washing procedure.

[0062] Step S302: Get the current washing program.

[0063] Step S303: Obtain the current detergent usage.

[0064] Step S304: Based on the first corresponding relationship, determine that the foam amount corresponding to the current washing program and the current detergent usage is a preset foam amount.

[0065] Step S305: Execute the water intake phase.

[0066] Step S306: Control the inner drum of the drum washing machine to rotate.

[0067] Step S307: After the inner drum rotates for a preset time, the amount of foam in the inner drum is obtained.

[0068] Step S308: Determine whether the amount of foam in the inner cylinder is greater than a preset amount of foam, if not, execute step S309, if yes, execute step S310.

[0069] Step S309: Control the drainage pump to intermittently reverse.

[0070] Step S310: After the washing process is finished, the drain pump is controlled to rotate forward.

[0071] like Figure 3As shown, as a second possible implementation, the control method of the washing device of the present invention includes the following steps:

[0072] Step S401: Execute a washing procedure.

[0073] Step S402: Get the current washing program.

[0074] Step S403: Obtain the current detergent usage.

[0075] Step S404: Based on the second corresponding relationship, determine that the turbidity value corresponding to the current washing program and the current detergent dosage is a preset turbidity value

[0076] Step S405: Execute the water intake phase.

[0077] Step S406: Control the inner drum of the drum washing machine to rotate.

[0078] Step S407: After the inner drum rotates for a preset time, the turbidity value is obtained.

[0079] Step S408: Determine whether the turbidity value in the inner cylinder is less than the preset turbidity value, if not, execute step S409, if yes, execute step S410.

[0080] Step S409: Control the drainage pump to intermittently reverse.

[0081] Step S410: After the washing process is finished, the drain pump is controlled to rotate forward.

[0082] On the other hand, the present invention also provides a washing device, in which a drain pump is arranged at a position lower than a drain outlet of the washing device, and the washing device also includes a memory and a processor, the memory is suitable for storing multiple program codes, and the program codes are suitable for being loaded and run by the processor to execute the control method of the washing device of any of the above-mentioned embodiments.

[0083] Those skilled in the art can understand that the above-mentioned washing device also includes some other well-known structures, such as a processor, a controller, a memory, etc., wherein the memory includes but is not limited to a random access memory, a flash memory, a read-only memory, a programmable read-only memory, a volatile memory, a non-volatile memory, a serial memory, a parallel memory or a register, etc., and the processor includes but is not limited to a CPLD / FPGA, a DSP, an ARM processor, a MIPS processor, etc. In order to unnecessarily obscure the embodiments of the present disclosure, these well-known structures are not shown in the drawings.

[0084] So far, the technical solutions of the present invention have 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.
