Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular provides a drainage control method for a washing device and a washing device. Background Art

[0002] In today's daily life, the application of washing equipment has brought ease and convenience to people. Through the use of washing equipment, people's hands can be liberated, labor time can be saved, and people's living comfort can be significantly improved.

[0003] Taking washing machines and shoe washers as examples, existing washing equipment includes washing machines and shoe washers, which can wash clothes and shoes. However, during the use of existing washing machines and shoe washers, it is inevitable that some foreign objects such as paper balls and hairpins will be put into the washing machine or shoe washer. These foreign objects will enter the drainage pump along with the water flow during the drainage process, causing the drainage pump to work abnormally.

[0004] In view of the above technical problems, the art needs a new technical solution to solve the above problems in the prior art. Summary of the invention

[0005] In order to solve the above problems in the prior art, that is, to solve the technical problem that during the use of the existing washing machines and shoe washing machines, foreign matter will enter the drainage pump along with the water flow during the drainage process, causing the drainage pump to work abnormally.

[0006] In a first aspect, the present invention provides a drainage control method for a washing device, wherein the washing device comprises a washing tub, and the washing device further comprises: a drainage pump for pumping out water in the washing tub; a drainage pipe, both ends of which are respectively connected to the washing tub and the drainage pump, so that the water in the washing tub flows out from the drainage pipe; a foreign matter collecting component, which is arranged on a side of the drainage pipe close to the drainage pump, and is used to collect foreign matter in the water flow passing through the drainage pipe; the drainage control method comprises: when the washing device executes a drainage mode, the drainage pump is operated intermittently to slow down the flow rate of the water flow so that the foreign matter in the water flow falls into the foreign matter collecting component.

[0007] In the preferred technical solution of the above-mentioned drainage control method, when the drainage pump is made to work intermittently, the drainage control method also includes: obtaining the flow rate of water flowing through the drainage pipe; and selectively switching the drainage pump from intermittent operation to continuous operation according to the flow rate.

[0008] In the preferred technical solution of the above-mentioned drainage control method, the drainage pump is selectively switched from intermittent operation to continuous operation according to the flow rate, specifically including: comparing the flow rate with a preset flow rate; and according to the comparison result, selectively switching the drainage pump from intermittent operation to continuous operation.

[0009] In the preferred technical solution of the above drainage control method, the drainage pump is selectively switched from intermittent operation to continuous operation based on the comparison result, specifically including: if the flow rate is greater than or equal to the preset flow rate, the drainage pump is not switched from intermittent operation to continuous operation.

[0010] In the preferred technical solution of the above drainage control method, the drainage pump is selectively switched from intermittent operation to continuous operation based on the comparison result, specifically including: if the flow rate is less than the preset flow rate, the drainage pump is switched from intermittent operation to continuous operation.

[0011] In the preferred technical solution of the above drainage control method, when the drainage pump is operated intermittently, the drainage control method further includes: when the intermittent operation time of the drainage pump reaches a first preset time, the drainage pump is switched from intermittent operation to continuous operation.

[0012] In the preferred technical solution of the above-mentioned drainage control method, making the drainage pump work intermittently specifically includes: stopping working when the drainage pump running time reaches a second preset time; starting running when the drainage pump stop time reaches a third preset time; wherein, the second preset time is greater than the third preset time.

[0013] In a preferred technical solution of the above drainage control method, the drainage control method further comprises: when it is detected that the foreign matter collecting component is full of foreign matter, stopping the drainage pump.

[0014] In a second aspect, the present invention provides a washing device, comprising a controller configured to execute the above drainage control method.

[0015] In the preferred technical solution of the above-mentioned washing device, the washing device is a washing machine or a shoe washing machine.

[0016] When adopting the above-mentioned technical scheme, the drainage control method provided by the present invention includes: when the washing equipment executes the drainage mode, the drainage pump is operated intermittently, so that the water flow rate can be prevented from being too fast so as to prevent the foreign matter moving with the water flow from moving too fast, and by slowing down the water flow rate, the foreign matter in the water flow falls into the foreign matter collection component, preventing the foreign matter from entering the drainage pump with the water flow, thereby protecting the drainage pump.

[0017] Furthermore, when the drain pump is operated intermittently, the drainage control method provided by the present invention also includes: obtaining the flow rate of water flowing through the drain pipe; and selectively switching the drain pump from intermittent operation to continuous operation according to the flow rate. In this way, the drain pump can switch the working state according to the actual flow rate in the drain pipe, thereby improving the drainage efficiency.

[0018] Furthermore, the above-mentioned step of selectively switching the drain pump from intermittent operation to continuous operation based on the flow rate specifically includes: comparing the flow rate with a preset flow rate; based on the comparison result, selectively switching the drain pump from intermittent operation to continuous operation; specifically, the comparison result has the following two situations, situation 1: the flow rate in the drain pipe is greater than or equal to the preset flow rate; situation 2: the flow rate in the drain pipe is less than the preset flow rate; the working state of the drain pump can be adjusted according to the above two situations.

[0019] Furthermore, if the flow rate is greater than or equal to the preset flow rate, that is, the comparison result is the above-mentioned situation 1, the drain pump will not be switched from intermittent operation to continuous operation; specifically, when the flow rate in the drain pipe is greater than or equal to the preset flow rate, it means that there is sufficient water and the water flow speed is still at a faster stage. Therefore, in order to reduce the flow rate, the drain pump should also be operated intermittently to reduce the flow rate, so as to make it easier for foreign matter in the water flow to fall into the foreign matter collection component.

[0020] Furthermore, if the flow rate is less than the preset flow rate, that is, the comparison result is the above-mentioned situation 2, the drainage pump is switched from intermittent operation to continuous operation; specifically, when the flow rate in the drain pipe is less than the preset flow rate, it means that the water is almost drained, and the water flow rate will decrease as the flow rate decreases. Therefore, at this time, there is no need to make the drainage pump work intermittently, but switch to continuous operation to improve drainage efficiency.

[0021] Furthermore, in the case where the drainage pump is made to work intermittently, the drainage control method provided by the present invention also includes: when the intermittent working time of the drainage pump reaches a first preset time, the drainage pump is switched from intermittent operation to continuous operation; specifically, when the intermittent working time of the drainage pump reaches the first preset time, it means that the drainage has been carried out for a period of time, and there is not much water left in the drainage pipe, the flow rate has been reduced, and therefore the flow rate will also be reduced. Therefore, at this time, the drainage pump is switched from intermittent operation to continuous operation to improve the drainage efficiency.

[0022] Furthermore, the step of making the drainage pump work intermittently specifically includes: stopping working when the drainage pump running time reaches a second preset time; starting running when the drainage pump stop time reaches a third preset time; wherein the second preset time is greater than the third preset time; through such a setting, it is beneficial to the collection of foreign matter and can improve the drainage efficiency.

[0023] Furthermore, the drainage control method provided by the present invention also includes: when it is detected that the foreign matter collecting component is full of foreign matter, the drainage pump is stopped; at this time, the foreign matter in the foreign matter collecting component should be cleaned up in time to facilitate the collection of foreign matter again.

[0024] In addition, the washing equipment further provided by the present invention on the basis of the above-mentioned technical scheme adopts the above-mentioned drainage control method, and thus has the technical effect of the above-mentioned drainage control method. Compared with the washing equipment before the improvement, the washing equipment of the present invention can slow down the flow rate of water during the drainage process so that foreign matter in the water flow falls into the foreign matter collection component, preventing foreign matter from entering the drainage pump with the water flow, thereby effectively protecting the drainage pump.

[0032] 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 used 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.

[0033] It should be noted that in the description of the present invention, the terms "upper", "lower", "left", "right", "inner", "outer", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the relevant devices or elements must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, in the description of the present invention, ordinal numbers "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0034] Based on the technical problem raised in the background technology, during the use of existing washing machines and shoe washing machines, foreign objects will enter the drainage pump along with the water flow during the drainage process, causing the drainage pump to work abnormally. The present invention aims to solve the above problem. Therefore, a drainage control method for a washing device and a washing device are provided. The drainage control method is applied to the washing device, which can slow down the flow rate of the water flow so that the foreign objects in the water flow fall into the foreign object collection component, preventing the foreign objects from entering the drainage pump along with the water flow, and effectively protecting the drainage pump.

[0035] Specifically, see Figure 1 The present invention provides a washing device, wherein the washing device includes a washing tub, a drain pump 1, a drain pipe 2 and a foreign matter collecting component 3, wherein the drain pump 1 is used to pump out water in the washing tub; both ends of the drain pipe 2 are respectively connected to the washing tub and the drain pump 1, so that the water in the washing tub flows out from the drain pipe 2; the foreign matter collecting component 3 is arranged on a side of the drain pipe 2 close to the drain pump 1, and is used to collect foreign matter in the water flowing through the drain pipe 2.

[0036] Based on the above-mentioned washing equipment, the present invention also provides a drainage control method for washing equipment, specifically, as follows: Figure 2 As shown, the drainage control method includes:

[0037] S100: When the washing machine executes the drainage mode, the drainage pump is operated intermittently to slow down the flow rate of the water flow so that foreign matter in the water flow falls into the foreign matter collecting component.

[0038] Exemplarily, before the washing equipment executes the drainage mode, those skilled in the art can set specific parameters for the intermittent operation of the drain pump 1. For example, 10 seconds can be set as an intermittent operation cycle of the drain pump 1. During this cycle, the drain pump 1 can work for 5 seconds, stop working for 5 seconds, and operate in this cycle. In this way, the flow rate of the water flow in the drain pipe 2 can be reduced to collect foreign matter in the water flow.

[0039] It should be noted that, in actual applications, those skilled in the art can set the specific parameters of the intermittent operation of the drainage pump 1 according to actual conditions. For example, an intermittent operation cycle of the drainage pump 1 is 8 seconds. During this cycle, the drainage pump 1 works for 5 seconds and stops working for 3 seconds, and so on. Such adjustments and changes to the specific parameters of the intermittent operation of the drainage pump 1 do not deviate from the principle and scope of the present invention and should be limited within the protection scope of the present invention.

[0040] In addition, it should be noted that in actual applications, the drainage pump can be made to work intermittently until the drainage is completed, or conditions can be set. When the set conditions are met, the drainage pump is switched from intermittent operation to continuous operation, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be limited within the scope of protection of the present invention.

[0041] In the first preferred case, if Figure 3 As shown, in the case where the drainage pump is made to work intermittently, the drainage control method provided by the present invention further includes:

[0042] S210: Obtaining the flow rate of water flowing through the drain pipe;

[0043] S300: According to the flow rate, the drainage pump is selectively switched from intermittent operation to continuous operation.

[0044] The drainage control method provided by the present invention can adjust the working state of the drainage pump 1 according to the flow rate in the drainage pipe 2, and when necessary, the drainage pump 1 can be switched from intermittent operation to continuous operation, thereby improving the drainage efficiency.

[0045] Exemplarily, a flow sensor can be set at the drain outlet of the washing tub to detect the flow rate of water, and the flow sensor is electrically connected to the controller of the washing equipment so that the detected flow data can be sent to the controller in a timely manner. The controller determines whether it is necessary to switch the drain pump from intermittent operation to continuous operation based on the acquired flow data.

[0046] Preferably, in step S300, according to the flow rate, the drainage pump is selectively switched from intermittent operation to continuous operation, specifically including:

[0047] S310: Compare the flow rate with the preset flow rate;

[0048] S320: Based on the comparison result, selectively switch the drainage pump from intermittent operation to continuous operation.

[0049] Specifically, the above comparison results have the following two situations:

[0050] Case 1: The flow rate is greater than or equal to the preset flow rate.

[0051] Case 2: The flow rate is less than the preset flow rate.

[0052] Preferably, according to the above comparison result, the drainage pump is selectively switched from intermittent operation to continuous operation, specifically including:

[0053] If the flow rate is greater than or equal to the preset flow rate, that is, the comparison result is the above-mentioned situation 1, step S321 is executed: the drainage pump is not switched from intermittent operation to continuous operation.

[0054] S321: Do not switch the drainage pump from intermittent operation to continuous operation.

[0055] Specifically, when the flow in the drain pipe 2 is greater than or equal to the preset flow, it means that there is sufficient water and the water flow speed is still at a relatively fast stage. Therefore, in order to reduce the flow speed, the drain pump 1 should be operated intermittently at this time to reduce the flow speed, so that foreign matter in the water flow can easily fall into the foreign matter collection component 3; therefore, when the flow in the drain pipe 2 is greater than or equal to the preset flow, the drain pump 1 will not be switched from intermittent operation to continuous operation.

[0056] Preferably, based on the above comparison results, the drainage pump is selectively switched from intermittent operation to continuous operation, specifically including: if the flow rate is less than the preset flow rate, that is, when the comparison result is the above situation 2, step S322 is executed: the drainage pump is switched from intermittent operation to continuous operation.

[0057] S322: Change the drainage pump from intermittent operation to continuous operation.

[0058] Specifically, when the flow in the drain pipe 2 is less than the preset flow, it means that the water is about to be drained, and the water flow rate will decrease as the flow decreases. Therefore, there is no need to make the drain pump 1 work intermittently at this time, and foreign matter will also fall into the foreign matter collection component 3. At this time, the drain pump 1 is switched from intermittent operation to continuous operation, which effectively improves the drainage efficiency and saves drainage time.

[0059] In the second preferred case, if Figure 4 As shown, in the case where the drainage pump is made to work intermittently, the drainage control method provided by the present invention further includes:

[0060] S220: When the intermittent operation time of the drainage pump reaches a first preset time, the drainage pump is switched from intermittent operation to continuous operation.

[0061] Specifically, when the intermittent working time of the drain pump 1 reaches the first preset time, it means that the drainage has been going on for a period of time, there is not much water left in the washing tub, the flow rate has decreased, and therefore the flow rate will also decrease. Therefore, at this time, the drain pump 1 is switched from intermittent operation to continuous operation to improve the drainage efficiency.

[0062] Exemplarily, the first preset time is 120 seconds. When drainage starts, the drainage pump is first operated intermittently. After 120 seconds, the drainage pump is switched from intermittent operation to continuous operation.

[0063] It should be noted that, in actual applications, technical personnel in this field can adjust the duration of the first preset time according to actual conditions. For example, the first preset time can also be 100 seconds or 150 seconds, etc. Such adjustment and change of the specific duration of the first preset time does not deviate from the principle and scope of the present invention and should be limited within the protection scope of the present invention.

[0064] Preferably, the method of making the drainage pump work intermittently provided by the present invention specifically includes:

[0065] S110: When the drain pump operation time reaches a second preset time, the drain pump stops working;

[0066] S120: When the stop time of the drainage pump reaches a third preset time, the drainage pump starts to operate;

[0067] The second preset time is greater than the third preset time.

[0068] Exemplarily, the second preset time is 10 seconds, and the third preset time is 5 seconds. When the running time of the drain pump 1 reaches 10 seconds, the drain pump 1 is briefly stopped for 5 seconds. That is, the drain pump 1 stops for 5 seconds and then restarts, then runs for 10 seconds and then stops for 5 seconds. The above operation is repeated until the drainage is completed or the drain pump is switched to continuous operation.

[0069] It should be noted that the specific values ​​of the second preset time and the third preset time are not limited to the above-mentioned 10 seconds and 5 seconds. In practical applications, technical personnel in this field can flexibly set them based on experiments or experience. Such adjustments and changes to the specific values ​​of the second preset time and the third preset time do not deviate from the principle and scope of the present invention, and should be limited within the protection scope of the present invention.

[0070] Preferably, the drainage control method provided by the present invention further includes:

[0071] When it is detected that the foreign matter collecting component is full of foreign matter, the drainage pump stops working.

[0072] At this time, the drainage pump 1 should be stopped and the foreign matter in the foreign matter collecting component 3 should be cleaned out in time so as to collect the foreign matter again.

[0073] The washing device provided by the present invention comprises a controller, and the controller can execute the above-mentioned drainage control method.

[0074] Preferably, the washing device provided by the present invention is a washing machine or a shoe washing machine.

[0075] 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.
