Description

Technical Field

[0001] The invention belongs to the field of washing equipment, and in particular relates to a washing equipment barrel self-cleaning device and a barrel self-cleaning method. Background Art

[0002] As an indispensable household appliance in modern families, washing machines occupy a large share of the home appliance market. However, during use, the stains produced are very easy to adhere to the outer wall of the inner drum and the inner wall of the outer drum, breeding bacteria and affecting the next washing effect. This affects the user experience and is not conducive to the long-term use of the product. At present, the solution to barrel self-cleaning is mainly to add elastic balls or high-pressure water flushing in the gap between the barrel walls. However, the use of this type of structure is unjudgmental. For example, the elastic balls are always colliding between the barrel walls. On the one hand, it has high requirements on the performance of the washing machine, and it is also very easy to wear after long-term use, affecting the cleaning effect.

[0003] The Chinese patent application number 201720475317.X discloses a washing machine drum cleaning system and a washing machine. A spray device is provided on the outer wall of the drum to spray water to a set area of ​​the drum. The water inlet of the spray device enters the water storage area of ​​the drum as the inner drum rotates, and then enters the spray device from the water inlet. The drum can be sprayed and cleaned without the help of a water pump. However, this cleaning structure will use a certain amount of water, resulting in a waste of resources.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a washing equipment barrel self-cleaning device and a barrel self-cleaning method. A magnetic suction component is used to clean the stains on the washing equipment barrel. A magnetic suction unit is arranged on the barrel wall of the outer barrel of the washing equipment. The cleaning ball is adsorbed on the magnetic suction unit when not working. When it needs to work, it falls off from the magnetic suction unit and moves freely between the inner and outer barrels, thereby achieving the effect of cleaning the washing equipment barrel.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0007] A first aspect of the present invention provides a washing equipment barrel self-cleaning device, comprising a magnetic suction component, for cleaning stains on the washing equipment barrel, wherein the magnetic suction component comprises:

[0008] A magnetic unit is arranged on the wall of the outer barrel of the washing equipment;

[0009] The cleaning ball is movably arranged between the outer barrel and the inner barrel of the washing device, and can be controllably adsorbed on the inner wall of the outer barrel by the magnetic attraction unit.

[0010] Specifically, when the barrel needs to be cleaned, the cleaning ball falls off the magnetic unit and moves freely between the inner and outer barrels with the water flow, thereby cleaning the barrel walls of the inner and outer barrels; when the inner and outer barrels do not need to be cleaned, the cleaning ball is adsorbed on the inner wall of the outer barrel due to the magnetic force of the magnetic unit.

[0011] Furthermore, the washing equipment barrel self-cleaning device also includes: a control unit, controlling the magnetic unit to release or absorb the cleaning ball; the control unit is communicatively connected with the magnetic unit.

[0012] Specifically, the control unit is communicatively connected with the magnetic unit. When the barrel needs to be self-cleaned, the control unit sends a signal to the magnetic unit to control the magnetic unit to release the cleaning ball. The cleaning ball falls off from the adsorption position and moves freely between the inner and outer barrels with the water flow to clean the stains on the inner and outer barrels. When the barrel is self-cleaned, the control unit sends a signal to the magnetic unit to control the magnetic unit to generate magnetic force to adsorb the cleaning ball to the adsorption position of the magnetic unit.

[0013] Furthermore, the washing equipment self-cleaning device also includes: a detection component for detecting the turbidity of the washing equipment barrel; the detection component is communicatively connected with the control unit.

[0014] Specifically, the detection component detects the dirtiness of the washing equipment barrel and feeds back the detection result to the control unit. After receiving the signal, the control unit controls the magnetic suction unit to absorb or release the cleaning ball.

[0015] In this embodiment, the monitoring and detecting component is configured as an infrared sensor, and the degree of dirtiness of the washing equipment barrel is detected by the infrared sensor.

[0016] A second aspect of the present invention provides a method for self-cleaning a washing equipment barrel, comprising:

[0018] S2, execute the barrel self-cleaning procedure;

[0019] S3, cleaning is completed, and the barrel self-cleaning program ends.

[0020] Optionally, in S1, the method for obtaining a signal for starting the barrel self-cleaning includes:

[0021] S11, the detection component detects whether the dirtiness of the barrel exceeds the cleaning threshold;

[0022] S12: If yes, the washing machine sends a prompt, and the user starts the washing machine barrel self-cleaning program.

[0023] Optionally, the detection component can be used to remind the user to start the barrel self-cleaning program of the washing equipment, and then obtain the barrel self-cleaning start signal. Alternatively, the barrel self-cleaning time can be set on the washing equipment, and when the barrel self-cleaning time is reached, the washing equipment starts the barrel self-cleaning program, thereby obtaining the barrel self-cleaning start signal.

[0024] Optionally, in S11, the detection component detects the dirtiness of the barrel once every period of time and compares it with the cleaning threshold.

[0025] Optionally, in S12, if the detection component detects that the dirtiness of the barrel does not exceed the cleaning threshold, the washing device does not start the barrel self-cleaning program.

[0026] Optionally, in S2, the method for executing the barrel self-cleaning program includes:

[0027] S21, the control unit receives a signal for starting the barrel self-cleaning;

[0028] S22, the control unit sends a command to the magnetic unit to control the magnetic unit to cut off power;

[0029] S23, the cleaning ball is separated from the magnetic unit and moves freely between the inner and outer barrels to complete the cleaning work.

[0030] Optionally, in S3, after the cleaning is completed, the detection component detects again whether the dirtiness of the barrel exceeds the cleaning threshold, and if so, the cleaning procedure continues.

[0031] Optionally, in S3, after the cleaning is completed, the detection component detects again that the dirtiness of the barrel does not exceed the cleaning threshold, the barrel self-cleaning program ends, and the method for recovering the cleaning ball includes:

[0032] S31, the control unit sends a command to the magnetic unit to control the magnetic unit to be powered on;

[0033] S32, the cleaning ball returns to the adsorption position under the action of the magnetic force of the magnetic attraction unit.

[0034] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art. By the user starting the barrel self-cleaning program at a fixed time or detecting the stains on the washing equipment barrel at irregular intervals and then cleaning, the breeding of bacteria can be reduced; by detecting the stains, the user can be reminded in time to clean the washing equipment barrel to keep the barrel clean; according to the detection, the barrel can be cleaned on demand, the loss caused by the long-term operation of the cleaning component can be reduced, and the service life and user experience can be improved; by cleaning the washing equipment barrel through the magnetic component, the waste of resources can be reduced.

[0045] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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.

[0046] like Figure 1 As shown, the first aspect of the present invention provides a self-cleaning device for a washing machine 1 barrel, comprising: a magnetic suction component 2, which cleans the stains on the washing machine 1 barrel.

[0047] Furthermore, the magnetic suction component 2 includes a magnetic suction unit 21 and a cleaning ball 22, the magnetic suction unit 21 is arranged on the barrel wall of the outer barrel 11 of the washing device 1; the cleaning ball 22 is movably arranged between the outer barrel 11 and the inner barrel 12 of the washing device 1, and can be controllably adsorbed on the inner wall of the outer barrel 11 by the magnetic suction unit.

[0048] Specifically, a magnetic unit 21 is provided inside the outer barrel 11 of the washing device 1. When the washing device 1 does not need to clean the barrel, the cleaning ball 22 is adsorbed on the inner wall of the outer barrel 11 by the suction force of the magnetic unit 21. When the barrel needs to be cleaned, the cleaning ball 22 falls off the magnetic unit 21 and moves freely between the inner barrel 12 and the outer barrel 11 with the water flow, thereby cleaning the barrel wall.

[0049] Furthermore, the washing equipment 1 barrel self-cleaning device also includes: a control unit, which controls the magnetic unit 21 to release or absorb the cleaning ball 22; the control unit is communicatively connected with the magnetic unit 21.

[0050] Specifically, the control unit is communicatively connected with the magnetic unit 21. When the washing device 1 needs to perform barrel self-cleaning, the control unit receives a signal to start the barrel self-cleaning program, and sends a control signal to the magnetic unit 21 to control the magnetic unit 21 to cut off the power, and the magnetic force disappears. Since the magnetic unit 21 has no magnetic force, the cleaning ball 22 falls off from the adsorption position and moves freely between the inner barrel 12 and the outer barrel 11 with the water flow, thereby achieving barrel cleaning; when the washing device 1 completes barrel self-cleaning or does not need to perform barrel self-cleaning, the control unit sends a signal to the magnetic unit 21 to control the magnetic unit 21 to be powered on, generating magnetic force, and the cleaning ball 22 returns to the position of the magnetic unit 21 under the adsorption of the magnetic force of the magnetic unit 21, thereby achieving the recovery of the cleaning ball 22.

[0051] Furthermore, the washing equipment 1 barrel self-cleaning device also includes: a detection component for detecting the turbidity of the washing equipment 1 barrel; the detection component is communicatively connected with the control unit.

[0052] Specifically, the detection component detects the degree of dirtiness of the outer wall of the inner barrel 12 and the inner wall of the outer barrel 11, determines that the washing device 1 needs to perform self-cleaning, and feeds back the detection result to the control unit. After receiving the feedback, the washing device 1 reminds the user to start the barrel self-cleaning program. After receiving the prompt, the user starts the self-cleaning program of the washing device 1. At the same time, the control unit receives the signal that the barrel self-cleaning program is started, and then sends a signal to the magnetic unit to control the magnetic unit 21 to cut off power. At this time, the magnetic unit 21 no longer has magnetic force, and the cleaning ball 22 falls off the magnetic unit 21, and moves freely between the inner barrel 12 and the outer barrel 11 with the water flow, thereby cleaning the outer wall of the inner barrel 12 and the inner wall of the outer barrel 11.

[0053] In this embodiment, the detection component is an infrared sensor, and the infrared sensor is communicatively connected with the control unit.

[0054] Specifically, the infrared sensor detects the degree of dirtiness of the outer wall of the inner barrel 12 and the inner wall of the outer barrel 11 of the washing device 1. If the detection result shows that the washing device 1 needs to be self-cleaned, a signal is sent to the control unit. After receiving the signal from the infrared sensor, the control unit sends a signal to the magnetic unit 21 to control the magnetic unit 21 to cut off the power. After the magnetic unit 21 is powered off, the magnetic force disappears, the cleaning ball 22 falls off the magnetic unit 21, and moves freely between the inner barrel 12 and the outer barrel 11, thereby cleaning the outer wall of the inner barrel 12 and the inner wall of the outer barrel 11 of the washing device 1.

[0055] Another aspect of the present invention provides a method for self-cleaning a washing machine 1 barrel, such as Figures 2 to 4 As shown, it includes steps S1 to S3.

[0056] In step S1, a signal for starting tub self-cleaning is obtained.

[0057] The method for obtaining the barrel self-cleaning requirement includes S11 to S12.

[0058] Optionally, the method for obtaining the barrel self-cleaning requirement also includes: S11 to S12.

[0059] In step S11 , the detection component detects whether the dirtiness of the barrel exceeds a cleaning threshold.

[0060] Specifically, according to the above description of the device, the detection component is an infrared sensor, which detects whether there are stains on the outer wall of the inner barrel 12 and the inner wall of the outer barrel 11, and detects the degree of dirt. The detected dirtiness of the barrel is compared with the set cleaning threshold to determine whether the washing device 1 needs to start the barrel self-cleaning program.

[0061] In step S12, if yes, the washing device 1 issues a prompt, and the user starts the self-cleaning program of the washing device 1.

[0062] Specifically, if the detection component detects that there are stains on the outer wall of the inner barrel 12 and the inner wall of the outer barrel 11, and the dirtiness exceeds the cleaning threshold, the washing device 1 emits a prompt sound to remind the user that the barrel needs to be self-cleaned. After the user receives the prompt sound initiated by the washing device 1, the barrel self-cleaning program of the washing device 1 is turned on, and the washing device 1 starts self-cleaning the barrel, and then receives a signal to start the barrel self-cleaning program.

[0063] Optionally, the time for tub self-cleaning may be set on the washing device 1. When the tub self-cleaning time is reached, the washing device 1 starts the tub self-cleaning program, thereby obtaining a signal for starting the tub self-cleaning program.

[0064] Optionally, in S11, the detection component detects the dirtiness of the barrel once every period of time and compares it with the cleaning threshold.

[0065] Specifically, the dirtiness of the barrel wall of the washing device 1 is detected by the detection component, and it is determined whether the barrel of the washing device 1 needs to be cleaned according to the detection result. After the cleaning is completed, the barrel cleaning program ends. After the washing device 1 has been used for a period of time, the detection component detects the inner and outer barrels of the washing device 1 again, and determines whether the dirtiness exceeds the cleaning threshold through the detection, and whether the barrel of the washing device 1 needs to be cleaned.

[0066] Optionally, in step S12, if it is detected that the dirtiness of the tub of the washing device 1 does not exceed the cleaning threshold, the washing device 1 does not start the tub self-cleaning program.

[0067] Specifically, if the detection component detects that the degree of dirt on the outer wall of the inner barrel 12 and the inner wall of the outer barrel 11 does not exceed the cleaning threshold, the washing device 1 will not emit a prompt sound, the user will not start the barrel self-cleaning program of the washing device 1, and the washing device 1 will not perform barrel self-cleaning.

[0068] In step S2, a barrel self-cleaning procedure is performed.

[0069] Optionally, the method of the barrel self-cleaning program includes: steps S21 to S23.

[0070] In step S21, the control unit receives a signal for starting tub self-cleaning.

[0071] Specifically, the user starts the barrel self-cleaning program at the barrel self-cleaning time set by the washing device 1, or after detection by the detection component, the washing device 1 needs to perform barrel self-cleaning. At this time, the washing device 1 transmits the signal of the barrel self-cleaning requirement to the control unit, and the control unit receives the signal of starting the barrel self-cleaning.

[0072] In step S22 , the control unit sends an instruction to the magnetic attraction unit 21 to control the magnetic attraction unit 21 to cut off power.

[0073] In step S23, the cleaning ball 22 is separated from the magnetic unit 21 and moves freely between the inner and outer barrels to complete the cleaning work.

[0074] Specifically, after the control unit receives the signal for starting the self-cleaning of the washing machine 1, the self-cleaning program of the washing machine 1 is started. First, the water inlet valve is opened to fill water into the washing machine 1. After the water filling is completed, the control unit sends a command to the magnetic unit 21 to control the magnetic unit 21 to cut off the power. After the magnetic unit 21 receives the command sent by the control unit, the magnetic unit 21 is cut off, the magnetic force disappears, and the cleaning ball 22 is separated from the preset position, and moves freely with the water flow between the inner barrel 12 and the outer barrel 11 of the washing machine 1 to clean the outer wall of the inner barrel 12 and the inner wall of the outer barrel 11.

[0075] In step S3, after the cleaning is completed, the barrel self-cleaning program ends.

[0076] Optionally, after cleaning is completed, the detection component detects the dirtiness of the inner and outer barrels of the washing device 1 again, and compares it with the cleaning threshold to determine whether it exceeds the cleaning threshold. If so, the washing device 1 continues to clean the barrel, otherwise, the barrel self-cleaning program ends.

[0077] Optionally, in step S3, after cleaning is completed, the detection component detects again that the dirtiness of the barrel does not exceed the cleaning threshold, the barrel self-cleaning program ends, and steps S31 to S32 are executed to recycle the cleaning ball 22.

[0078] In step S31 , the control unit sends a signal directly to the magnetic unit 21 to control the magnetic unit 21 to be powered on.

[0079] In step S32 , the cleaning ball 22 returns to the adsorption position under the action of the magnetic force of the magnetic attraction unit 21 .

[0080] Specifically, after the barrel self-cleaning program ends, the control unit receives a signal indicating the end of the barrel self-cleaning program, and sends an instruction to the magnetic unit 21 to control the magnetic unit 21 to be powered on. After the magnetic unit 21 is powered on, a magnetic force is generated, and the cleaning ball 22 returns to the adsorption position under the attraction of the magnetic force of the magnetic unit 21, that is, the position of the outer barrel 11 where the magnetic unit 21 is set, and is adsorbed on the magnetic unit 21.

[0081] More specifically, after the barrel self-cleaning program is completed, the washing device 1 drains the cleaning water, and then the cleaning balls fall to the bottom of the outer barrel 11 as the water is discharged, and then are recovered to the adsorption position along the set magnetic attraction line.

[0082] Washing equipment 1 is a household appliance used in our daily life. In addition to washing clothes, we should also pay attention to the cleanliness of washing equipment 1. The washing equipment 1 commonly used in our lives is divided into drum washing machines and pulsator washing machines. For the two different washing machines, the arrangement of the magnetic suction component 2 and the magnetic suction line is different according to the actual situation. In the drum washing machine, in order to reduce the influence of cleaning water on the magnetic suction component 2, the magnetic suction component 2 is set in the upper half of the outer drum, and the magnetic suction line is set on the outer wall of the outer drum or inside the outer drum wall. The magnetic suction line is set to extend upward along the lowest point of the lower half of the outer drum until the position of the magnetic suction component 2 is set.

[0083] For a pulsator washing machine, in order to reduce the impact of cleaning water on the magnetic component 2, the magnetic component 2 is set near the upper edge of the barrel, and the magnetic line is also set on the outer wall of the outer barrel or inside the outer barrel wall, extending from the bottom of the barrel to the installation position of the magnetic component 2.

[0084] In this embodiment, a self-cleaning device and a self-cleaning method for a washing machine 1 are provided. The self-cleaning program of the washing machine 1 is started by setting a self-cleaning time, or the detection component detects whether there are stains attached to the outer wall of the inner barrel 12 and the inner wall of the outer barrel 11 of the washing machine 1 from time to time, and detects the degree of dirtiness, and starts the self-cleaning program of the washing machine 1.

[0085] In this embodiment, the self-cleaning program of the washing machine 1 is started. After the control unit receives the signal that the self-cleaning program of the washing machine 1 is started, it sends a signal to the magnetic unit 21 to control the magnetic unit 21 to cut off the power. The magnetic unit 21 is an electromagnet. After the power is cut off, there is no magnetic force. The cleaning ball 22 falls from the preset position and moves freely along the outer wall of the inner barrel 12 and the inner wall of the outer barrel 11 of the washing machine 1 with the water flow to clean the inner and outer barrels of the washing machine 1.

[0086] In this embodiment, after the cleaning is completed, the detection component again detects whether the dirtiness of the inner and outer barrels of the washing device 1 is higher than the cleaning threshold. If it is higher than the cleaning threshold, the barrel self-cleaning program continues; if it is lower than the cleaning threshold, the barrel self-cleaning program of the washing device 1 ends.

[0087] In this embodiment, after the barrel self-cleaning program ends, the washing device 1 drains the cleaning water, and then the control unit sends a signal to the magnetic unit 21 to control the magnetic unit 21 to be powered on to generate magnetic force, and the cleaning ball 22 returns to the adsorption position under the attraction of the magnetic force of the magnetic unit 21 to prepare for the next cleaning.

[0088] Specifically, a magnetic line is provided on the outer wall of the outer barrel 11 or inside the wall of the outer barrel 11. The cleaning ball 22 is attracted by the magnetic line and adsorbed to the adsorption position closest to the cleaning ball 22. It may happen that multiple cleaning balls 22 are adsorbed at the same position and are connected in a series and adsorbed together by the magnetic force of the magnetic line and the magnetic unit 21. Through the action of the magnetic line and the magnetic unit 21, the cleaning ball 22 is recovered to prepare for the next barrel self-cleaning.

[0089] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation scheme in the above embodiment can also be further combined or replaced. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of the solution of the present invention.
