The control method of the present invention is described below using a drum washing machine as an example.

[0026] It should be noted that, in the description of the present invention, the term "inside" and other terms indicating direction or position relationship are based on the direction or position relationship shown in the drawings. This is only for the convenience of description, and does not indicate or imply that the relevant devices or elements must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0027] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the term "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 a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] In addition, it should be noted that in the description of the present invention, although the various steps of the control method of the present invention are described in this application in a specific order, these orders are not restrictive. Without departing from the basic principles of the present invention, those skilled in the art can perform the steps in a different order.

[0029] See first Figure 1 , which is a schematic diagram of the structure of the washing device of the present invention. Figure 1 As shown, the washing device includes a housing 1, a washing tub 2 arranged in the housing 1, a pump component 3, a connecting pipeline 4, a drainage pipeline 5, a circulation pipeline 6, a float 7 and a spray device 8. The washing tub 2 includes an inner tub 21 and an outer tub 22. The inner tub 21 is rotatably arranged in the outer tub 22. A gap cavity 23 is formed between the inner tub 21 and the outer tub 22. Clothes to be washed are placed in the inner tub 21. A drainage port 222 communicating with the gap cavity 23 is arranged on the outer tub 22. The drainage port 222 is communicated with the water inlet of the pump component 3 through the connecting pipeline 4. The water outlet of the pump component 3 can be selectively communicated with the drainage pipeline 5 or the circulation pipeline 6. The circulation pipeline 6 is further communicated with the spray device 8. The spray device 8 is configured to spray the inner tub 21. Specifically, when the water outlet of the pump component 3 is connected to the drainage pipeline 5, the washing tub 2 is in a drainage state. When the water outlet of the pump component 3 is connected to the circulation pipeline 6, the washing tub 2 is in a circulation spray state.

[0030] Exemplarily, the pump component 3 is configured as a water pump, and the pump component 3 is provided with two water outlets, which are respectively connected to the drainage pipeline 5 and the circulation pipeline 6. The drainage pipeline 5 and the circulation pipeline 6 are respectively provided with valves, and the opening and closing of the valves are controlled to achieve the selective communication of the water outlet of the pump component 3 with the drainage pipeline 5 or the circulation pipeline 6. Of course, the pump component 3 may also be provided with only one water outlet, which is respectively connected to the drainage pipeline 5 and the circulation pipeline 6 through valves at the water outlet. The present invention does not limit the connection structure between the pump component 3 and the drainage pipeline 5 and the circulation pipeline 6, as long as the water outlet of the pump component 3 can be selectively connected to the drainage pipeline 5 or the circulation pipeline 6.

[0031] Continue as Figure 1 As shown, a cavity 221 connected to the drain outlet 222 and extending downward is provided at the lower part thereof, the cavity 221 is connected to the connecting pipe 4, and the float 7 is provided in the cavity 221. When the float 7 rises relatively in the cavity 221, the drain outlet 222 can be closed, and when the float 7 falls relatively in the cavity 221, the drain outlet 222 can be opened. The float 7 is made of foam material as a whole, and is in the shape of a sphere with a horizontally cut bottom. The center of gravity is always located at the lower part of the float 7 as a whole. When the float 7 is placed in water, the float 7 rises relatively in the cavity 221, and the bottom of the float 7 is always located in the water, so that the drain port 222 can be closed, thereby blocking the drain port 222 from the connecting pipe 4. When the pump component 3 is started and running, the float 7 descends relatively in the cavity 221 under the action of the suction force of the pump component 3, so that the float 7 is separated from the drain port 222, so that the drain port 222 can be opened, thereby connecting the drain port 222 with the connecting pipe 4.

[0032] Furthermore, a magnetic member 71 (such as a magnet) is provided at the bottom of the float 7, and the provision of the magnetic member 71 can ensure the overall balance of the float 7. An induction coil 9 that can be electrically connected to the magnetic member 71 is provided inside the inner side of the lower part of the drain outlet 222, i.e., in the cavity 221. When water enters the washing tub 2, the float 7 rises under the buoyancy of the water. When it rises to a certain height, i.e., when the induction coil 9 can sense the magnetic member 71, it indicates that the float 7 closes the drain outlet 222.

[0033] Furthermore, a limiting member 10 is provided at the port of the drain outlet 222 . Exemplarily, the limiting member 10 is an overall closed structure to limit the float 7 and prevent the float 7 from entering the washing tub 2 .

[0034] See below Figure 2 , which is a flow chart of the main steps of the control method of the washing equipment of the present invention. Figure 2 As shown, the control method of the present invention comprises the following steps:

[0035] S1, before the washing device starts the washing program, controlling the washing device to execute the residual water discharge program;

[0036] The specific steps of "washing equipment executing residual water discharge procedure" include:

[0037] S11, water is introduced into the washing tub 2;

[0038] S12, when the drain port 222 is closed, the pump component 3 is controlled to start and operate so as to open the drain port 222 and control the washing tub 2 to be in a draining state.

[0039] In step S11, the step of "introducing water into the washing tub 2" specifically includes:

[0040] S111 , water is introduced into the inner tube 21 , and the water in the gap cavity 23 does not contact the inner tube 21 .

[0041] In step S12, the step of "controlling the washing tub 2 to be in a draining state" specifically includes:

[0042] S121, controlling the water outlet of the pump component 3 to communicate with the drainage pipeline 5.

[0043] In the above steps, since the connecting pipe 4 between the drain port 222 and the pump member 3 retains residual sewage that has not been discharged after the last washing process, in order to avoid the residual sewage in the connecting pipe 4 from contaminating the clothes, the residual water discharge process is performed before the washing device starts the washing process. Specifically, by first filling water into the washing drum 2, at this time, the float 7 closes the drain port 222 under the buoyancy of the water, so that the washing drum 2 and the connecting pipe 4 are blocked, so that the residual sewage in the connecting pipe 4 will not enter the washing drum 2. When filling water, the water intake is controlled not to exceed the bottom of the inner drum 21, that is, in the gap cavity 23 between the inner drum 21 and the outer drum 22, so as to avoid the water entering the outer drum 22 from being contaminated with the clothes to be washed in the inner drum 21, and further avoid the clothes to be washed from being contaminated. Then, the pump component 3 is controlled to start and run, so that the drain port 222 is opened, and the water outlet of the pump component 3 is controlled to be connected with the drain pipe 5, so that the washing drum 2 is in a draining state, thereby discharging the connecting hose together with the water in the gap cavity 23, realizing the residual water discharge action, and the connecting hose can also be flushed by the water in the gap cavity 23 to ensure that the clothes are not contaminated during subsequent washing.

[0044] The control method of the present invention further includes:

[0045] When the washing machine starts a washing program, the pump member 3 is controlled to be closed and water is fed into the washing tub 2;

[0046] When the drain port 222 is closed, water and / or detergent is added into the washing tub 2;

[0047] The pump component 3 is controlled to continue to operate so that the drain port 222 is opened, and the washing tub 2 is controlled to be in a circulating spraying state.

[0048] The step of "controlling the washing drum 2 to be in a circulating spraying state" specifically includes:

[0049] The water outlet of the control pump component 3 is communicated with the circulation pipeline 6 .

[0050] In the above steps, after the residual water discharge procedure of the washing device is finished, the pump component 3 is controlled to be closed, and water continues to be introduced into the washing tub 2, so that the float 7 closes the drain port 222 under the buoyancy of the water, so that the washing tub 2 is blocked from the connecting pipeline 4. Then water and / or detergent are added into the washing tub 2, and at the same time or after the water and / or detergent are added into the washing tub 2, the pump component 3 is controlled to operate, so that the drain port 222 is opened, and the water outlet of the pump component 3 is controlled to be connected with the circulation pipeline 6, so that the water in the washing tub 2 is sprayed into the washing tub 2 through the circulation pipeline 6 and the spray device 8, so that the washing device is in a circulation spraying state.

[0051] The detergent may be laundry liquid or laundry powder.

[0052] Specifically, in the washing stage and the rinsing stage, by adopting a circulating spray washing method, the washing water is recycled and sprayed onto the laundry, which can fully utilize the washing water, achieve fast washing and improve washing efficiency.

[0053] The control method of the present invention further includes:

[0054] In the washing stage, the parameter values ​​of the washing water in the washing tub 2 are obtained;

[0055] When the parameter value of the washing water is higher than the preset parameter value, the amount of detergent added to the washing equipment and the number of washes are increased.

[0056] In the above steps, during the circulating spray washing process in the washing stage, the parameter value of the washing water is detected. When the parameter value of the washing water exceeds the preset parameter value, it means that the washed clothes are too dirty. The cleanliness of the clothes is ensured by increasing the amount of detergent and the number of washes.

[0057] Exemplarily, the parameter value of the washing water is at least one of the turbidity value and the pH value of the washing water. Of course, in addition to the turbidity value and the pH value mentioned above, the parameter value of the washing water may also be the hardness value, the conductivity, etc. of the washing water. Among them, those skilled in the art may set a turbidity sensor in the washing tub 2 to detect the turbidity value of the washing water, and set a pH sensor in the washing tub 2 to detect the pH value of the washing water. In addition, the preset parameter value is set according to actual needs in this field, and is not limited in the present invention.

[0058] The control method of the present invention further includes:

[0059] In the rinsing stage, the turbidity value of the washing water in the washing tub 2 is obtained;

[0060] When the turbidity value of the washing water is higher than the preset turbidity value, the washing tub 2 is controlled to be in a drainage state;

[0061] When the turbidity value of the washing water is lower than the preset turbidity value, the washing tub 2 is controlled to continue to be in a circulating spraying state.

[0062] In the above steps, during the cyclic spray rinsing process, when the turbidity value of the washing water is higher than the preset turbidity value, it means that the washing water is not suitable for continued rinsing at this time, and the sewage needs to be discharged to re-introduce water for rinsing. When the turbidity value of the washing water is lower than the preset turbidity value, it means that the washing water can still continue to be rinsed at this time, and after multiple cyclic spraying cycles set by the program, the turbidity value of the washing water remains unchanged, then the washing equipment proceeds normally according to the set program until the washing is completed.

[0063] Specifically, by using the method for controlling the amount of detergent, the number of washes and the number of rinses in the present invention, when the user selects the intelligent state for washing, the washing machine can automatically select the amount of detergent, the number of washes and the number of rinses according to the degree of dirtiness of the clothes during the washing process without the need for human judgment. While improving the cleaning ratio, it avoids the waste of water and electricity resources due to improper program selection, and provides a better user experience.

[0064] The control method of the present invention further includes:

[0065] Before the washing machine starts a washing program, the weight and / or material of the laundry in the washing tub 2 is obtained;

[0066] The amount of water and / or detergent to be added is determined based on the weight and / or material of the laundry.

[0067] In the above steps, the weight of the clothes to be washed can be obtained by fuzzy weighing or by setting a weight sensor on the inner drum 21, and the material of the clothes to be washed can be obtained by adopting AI camera recognition technology, spectral analysis technology, etc., and the present invention is not limited to this.

[0068] Those skilled in the art will pre-store the mapping relationship between the different materials and weights of clothes and the amount of water and / or detergent sprayed, and then match the corresponding amount of water and / or detergent sprayed based on the actual weight and / or material of the clothes to be washed. For example, the greater the weight of the clothes to be washed, the greater the amount of water and / or detergent sprayed, and the longer the spraying time. Under the same weight, since the corresponding water absorption amount of clothes of different materials is different, for example, the amount of water and / or detergent sprayed required for cotton clothes is greater than that required for chemical fiber clothes. Correspondingly, the spraying time of water and / or detergent required for cotton clothes is longer than that required for chemical fiber clothes.

[0069] In the embodiments of the present invention, by accurately controlling the spraying amount of water and / or detergent based on the weight and / or material of the clothes to be washed, the cleaning effect of the clothes can be ensured and the purpose of saving water can be achieved.

[0070] Further, the number of washes and the number of rinses can also be controlled according to the weight and / or material of the clothes to be washed. In addition, the user can also customize the number of washes and / or the number of rinses according to actual cleaning needs.

[0071] In addition, the washing machine can perform a residual water draining procedure before or after the laundry is put in. Exemplarily, when the residual water draining procedure is performed after the laundry is put in, when water is inletted, the water sprayed into the inner drum 21 will first soak the laundry and then enter the gap cavity 23 between the inner drum 21 and the outer drum 22. At this time, the amount of water inletted during the washing procedure will be additionally increased based on the weight and / or material of the laundry to ensure the normal subsequent washing.

[0072] See below Figure 3 , a possible control process of the present invention is introduced. Figure 3 As shown, a possible complete process of the control method of the present invention is:

[0073] S101, obtaining the weight and / or material of the laundry in the washing tub 2;

[0074] S102, determining the amount of water and / or detergent to be added based on the weight and / or material of the laundry;

[0075] S103, controlling the washing equipment to execute a residual water discharge procedure;

[0076] S104, controlling the washing equipment to execute a washing program.

[0077] Based on the above embodiments, the present invention further provides a washing device, including a controller, wherein the controller is configured to be able to implement the above control method.

[0078] 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.
