DETAILED DESCRIPTION
[0030] In order to make the purpose, technical solution and effect of this application clearer and more specific, the technical solution in the embodiment of this application will be clearly and completely described below in conjunction with the drawings in the embodiment of this application. Obviously, the described embodiment is only a part of the embodiment of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0031] In related technologies, such as Figure 1 , Figure 2 and Figure 3 As shown, the drainage process of the drum washing machine is to pump out the sewage in the washing container 100 of the drum washing machine through the drainage pump 300 and the drainage bellows 200 connected between the washing drainage port 110 and the pump water inlet 310, and then discharge the sewage to the floor drain or sewer pipe of the user's home through the drainage pipe 400 connected to the pump drainage port 320. The sewer pipe is directly connected to the washing container 100 through the drainage pipe 400, the drainage pump 300, and the drainage bellows 200. Various harmful insects such as cockroaches in the sewer pipe, various harmful bacteria, and even sewage in the sewer pipe can directly enter the washing tub, thereby seriously affecting the sanitary state in the washing tub and endangering the health of the user.
[0032] Conventional drum washing machine: ① By raising the drain pipe 400, a height difference is formed between the highest point of the drain pipe 400 and the drain pump 300, thereby preventing the water in the washing container 100 (washing tub) from flowing directly out of the drain pipe 400 during washing, and at the same time preventing the sewage in the sewer pipe from siphoning back into the washing container 100. This solution cannot solve the problem that insects such as cockroaches and various harmful germs in the sewer pipe enter the washing tub (washing container 100). ② By setting a blocking rib in the impeller cavity of the drain pump 300, it can, to a certain extent, prevent larger harmful insects from entering the washing tub. This solution cannot solve the problem that smaller harmful insects, various harmful germs and sewage enter the washing tub (washing container 100).
[0033] This application can be applied to washing machines, specifically in the following scenarios: applicable scenarios such as pulsator washing machines, drum washing machines, and agitator washing machines.
[0034] Regarding the problem in the related art mentioned above that the drain pipe 400 of the washing machine is aligned with the sewer pipe, resulting in the easy entry of organisms in the sewer pipe into the washing tub, this application provides a drainage check structure and a washing machine for healthy washing of the washing machine. In this drainage check structure, the elastic check valve 20 prevents organisms in the sewer pipe from entering the washing container 100 through the liquid discharge hole 101, and enables the liquid in the washing container 100 to flow out of the liquid discharge hole 101 to the sewer pipe under the action of gravity, thereby effectively blocking the entry of harmful insects such as cockroaches, harmful germs, and sewage in the sewer pipe into the washing container 100, and further keeping a hygienic and healthy environment in the washing container 100 all the time, ensuring the washing health of users. Thus, the technical problem in the related art that the drain pipe 400 of the washing machine is aligned with the sewer pipe, resulting in the easy entry of organisms in the sewer pipe into the washing tub, is solved.
[0035] The following uses specific embodiments to elaborate in detail on the technical solution of this application and how the technical solution of this application solves the above technical problems. These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.
[0036] In the embodiment of this application, the drainage check structure for healthy washing of the washing machine can overcome the problem that currently it is unable to effectively block the entry of harmful insects such as cockroaches, harmful germs, and sewage in the sewer pipe into the washing container 100, thereby keeping a hygienic and healthy environment in the washing container 100 all the time, ensuring the washing health of users.
[0037] It can be understood that organisms include all life forms from simple single-celled organisms such as bacteria to complex multi-cellular organisms such as plants and animals. Organisms include insects, germs, and other smaller life forms. Sewage contains germs, so this application can prevent insects, germs, sewage, etc. in the sewer pipe from entering the washing container 100.
[0038] As Figure 4 shown, an embodiment of this application provides a drainage check structure for healthy washing of a washing machine. The drainage check structure for healthy washing of the washing machine is installed in the drainage port of the washing container 100, facing the sewer pipe; the drainage check structure for healthy washing of the washing machine includes a support assembly 10 and an elastic check valve 20. The support assembly 10 is connected to the inner wall of the drainage port, and the support assembly 10 has a liquid discharge hole 101; the elastic check valve 20 fits against the bottom end of the support assembly 10 in the initial state to block the liquid discharge hole 101, and disengages from the bottom end of the support assembly 10 in the elastic state to dredge the liquid discharge hole 101; the elastic check valve 20 is used to prevent organisms in the sewer pipe from entering the washing container 100 through the liquid discharge hole 101, and to allow the liquid in the washing container 100 to flow out of the liquid discharge hole 101 to the sewer pipe under the action of gravity.
[0039] It should be noted that the drainage port of the washing container 100 corresponds to Figure 2 the washing drainage port 110 in
[0040] Specifically, as Figure 4 and Figure 5 shown, the washing drainage port 110 is a circular hole, but is not limited thereto, and can also be set as a square hole. The support assembly 10 is installed on the inner wall of the circular hole. The support assembly 10 can be made of the same material as the periphery of the washing drainage port 110, and the two are integrally formed or separately manufactured and installed; the elastic check valve 20 has elasticity. The initial state of the elastic check valve 20 is the state after rebounding, that is, at this time, the liquid discharge hole 101 is blocked (no liquid is discharged downward), and the elastic state of the check valve is the state in which the self-gravity of the liquid acts on the check valve to form its elastic deformation, that is, at this time, the liquid discharge hole 101 is dredged (liquid is discharged downward).
[0041] Furthermore, at least part of the structure of the elastic check valve 20 (i.e., the unsealing structure 22) is located below the support assembly 10, so that the liquid in the washing container 100 first passes through the liquid discharge hole 101 formed by the support assembly 10, and then the elastic check valve 20 releases the liquid discharge hole 101 due to the self-weight of the liquid, so that the liquid flows downward from the liquid discharge hole 101 to the sewer pipe. It should be noted that the sewer pipe is located below the washing drain port 110. Correspondingly, the support assembly 10 and the elastic check valve 20 are located above the sewer pipe, and the support assembly 10 and the elastic check valve 20 can be vertically installed (the unsealing structure 22 is installed directly below the support assembly 10) or inclinedly installed (the unsealing structure 22 is installed obliquely below the support assembly 10) to facilitate the liquid to flow downward smoothly from the liquid discharge hole 101 formed by the support assembly 10.
[0042] In an embodiment of the present application, refer to Figure 4 and Figure 5 , the support assembly 10 includes an annular structure 11 and a plurality of support ribs 12; the plurality of support ribs 12 are distributed on the outer side of the annular structure 11, and the annular structure 11 and every two support ribs 12 form a liquid discharge hole 101.
[0043] Specifically, the annular structure 11 is annular, and the annular structure 11 is used to install the elastic check valve 20. The plurality of support ribs 12 form at least one liquid discharge hole 101, and every two adjacent support ribs 12 form a liquid discharge hole 101. The plurality of support ribs 12 are arranged to be evenly distributed on the outer side of the annular structure, so as to form liquid discharge holes 101 with the same size. However, this is not limited thereto, and the layout of the support ribs 12 can also be set so that the formed liquid discharge holes 101 have different sizes, so as to facilitate the liquid in the washing container 100 to flush at least part of the elastic check valve 20 (unsealing structure 22) downward through the liquid discharge hole 101, so that the liquid can flow out smoothly to the sewer pipe.
[0044] In an embodiment of the present application, the number of the support ribs 12 is four, and the four support ribs 12 are in a cross shape.
[0045] Specifically, as Figure 4 and Figure 5 shown, the middle of the four support ribs 12 is connected to the annular structure 11. The annular structure 11 has an installation hole 102 for installing the elastic check valve 20. Four support ribs 12 are used to form four liquid discharge holes 101. The cross section of each liquid discharge hole 101 is fan-shaped, and the liquid can form a sufficient self-weight in the liquid discharge hole 101 to impact the unsealing structure 22, so as to discharge the liquid to the sewer pipe.
[0046] In an embodiment of the present application, refer to Figure 6, the elastic check valve 20 includes a mounting post 21 and a sealing structure 22; the annular structure 11 has a mounting hole 102, the mounting post 21 is connected to the annular structure 11 through the mounting hole 102, and the sealing structure 22 is connected to the lower end of the mounting post 21.
[0047] Specifically, as Figure 4 and Figure 6 shown, the center of the top of the sealing structure 22 is connected to the mounting post 21. The mounting post 21 is inserted into the mounting hole 102 of the annular structure 11 from bottom to top. The sealing structure 22 is located below the annular structure 11 and the plurality of drainage holes 101 formed by the plurality of support ribs 12. The sealing structure 22 can be opened by the self-gravity of the liquid from outside to inside, so that the liquid flows out from the drainage holes 101.
[0048] It can be understood that the resilience of the elastic check valve 20 can be adjusted by the hardness and cross-sectional shape structure of the elastic check valve 20, but not limited thereto. An auxiliary structure can also be provided to assist the elastic check valve 20 to rebound.
[0049] It should be noted that the material of the elastic check valve 20 is not limited to materials such as rubber and silica gel, and any elastic material is applicable.
[0050] In an embodiment of the present application, the cross-section of the sealing structure 22 is in an umbrella shape, and the umbrella-shaped converging end of the sealing structure 22 is connected to the lower end of the mounting hole 102.
[0051] Specifically, in this embodiment, the sealing structure 22 is an umbrella-shaped structure. The converging end of the umbrella-shaped structure is connected to the lower end of the annular structure 11 and blocks the mounting hole 102 to prevent the liquid from flowing out of the mounting hole 102.
[0052] In an embodiment of the present application, the cross-section of the sealing structure 22 is circular or square.
[0053] It can be understood that in this embodiment, the cross-section of the structure of the elastic check valve 20 is in an umbrella shape, but not limited thereto. The cross-section of the sealing structure 22 can also be set to be circular or square.
[0054] In an embodiment of the present application, the mounting post 21 has an anti-back structure 23, and the anti-back structure 23 abuts against the upper end surface of the annular structure 11.
[0055] Specifically, as Figure 4 and Figure 6 shown, the anti-back structure 23 in this embodiment is four anti-backs. The four anti-backs abut against the upper end surface of the annular structure 11, so as to prevent the elastic check valve 20 from being washed out when the liquid impacts the sealing structure 22 and ensure that the liquid will not flow out of the mounting hole 102.
[0056] In an embodiment of the present application, the lower end surface of the support rib 12 has an inclination with respect to the horizontal end surface. The upper surface of the sealing structure 22 in the initial state is attached to the lower end surface of the support rib 12. When the liquid in the washing container 100 flows through the upper surface of the sealing structure 22, the sealing structure 22 is switched to an elastic state.
[0057] Specifically, the sealing structure 22 is an umbrella-shaped structure, so that the inclined surface formed by the lower end surface of the support rib 12 is convenient for adapting to the upper surface of the umbrella-shaped structure, improving the tight fit degree, and further preventing insects and germs in the sewer pipe from entering the washing container 100 through the umbrella-shaped structure and the liquid discharge holes 101.
[0058] It should be noted that the support structure inside the drain outlet of the washing tub is not limited to the support rib 12 with an inclination.
[0059] In an embodiment of the present application, the annular structure 11 and the mounting post 21 are located at the center of the drain outlet, so that the liquid in the washing container 100 flows around the annular structure 11 to pass through the sealing structure 22.
[0060] Specifically, as Figure 4 and Figure 5 shown, the annular structure 11 and the mounting post 21 at the center are convenient for diverting the liquid (water) flowing downward in the washing container 100, so that the liquid converges into the plurality of liquid discharge holes 101 respectively. The self-weight and impact force of the liquid in the liquid discharge holes 101 switch the sealing structure 22 to an elastic state, so that the liquid in the washing container 100 flows downward through the liquid discharge holes 101 into the sewer pipe.
[0061] Next, in combination with Figure 4 、 Figure 5 and Figure 6 , the above-mentioned drainage check structure for the healthy washing of the washing machine in the present application will be further described through specific embodiments:
[0062] An elastic check valve is additionally installed inside the drain outlet of the washing tub. A number of rib positions are provided inside the drain outlet of the washing container 100 (i.e., the washing tub). The lower part of these rib positions needs to have an inclination, and an installation hole 102 is provided at the middle position of these rib positions; an installation post 21 is provided in the middle part of the elastic check valve 20, an inverted buckle structure 23 is provided on the installation post 21, and a structure similar to an umbrella-shaped structure is connected below the installation post 21; the elastic check valve 20 is installed in the installation hole 102 inside the drain outlet of the washing tub through the middle installation post 21 and fixed to the installation hole 102 through the inverted buckle structure 23 provided thereon, and the installation is simple; the sealing structure 22 (i.e., the umbrella-shaped structure) of the elastic check valve 20 is attached to the rib positions with an inclination in the radial direction inside the drain outlet of the washing tub, playing a function similar to that of a one-way valve.
[0063] When the drum washing machine drains water, the sewage in the washing tub can flow out normally through the elastic check valve 20 due to gravity; after the drainage is completed, the elastic check valve 20 will rebound and fit against the radial rib position (i.e., the bottom wall of the support rib 12) inside the drainage opening of the washing tub, completely blocking the drainage opening of the washing tub, thereby preventing harmful insects such as cockroaches, harmful germs, and sewage in the sewer from entering the washing tub.
[0064] Exemplarily, as Figure 3 shown, an embodiment of the present application further provides a washing machine, wherein the drainage check structure for healthy washing of the washing machine includes the drainage check structure for healthy washing of the washing machine according to any one of the above solutions, the washing machine further includes a washing container 100, the washing container 100 has a drainage opening, and the drainage check structure for healthy washing of the washing machine is installed in the drainage opening.
[0065] It should be noted that in the embodiment of the present application, the washing machine is a drum washing machine. For the structural solution of the drum washing machine with a drainage check function, by adding an elastic check valve 20 in the washing drainage opening 110, when the drum washing machine enters the drainage stage during operation, the sewage in the washing container 100 (washing tub) can flow out of the washing tub normally through the check valve, but various harmful insects such as cockroaches, various harmful germs, and even the sewage in the sewer pipe cannot enter the washing tub, ensuring the washing health of the user.
[0066] The washing machine provided by the embodiment of the present application has all the above beneficial effects due to the drainage check structure for healthy washing of the washing machine described in any one of the above technical solutions, and will not be elaborated here.
[0067] A control method for the drainage check structure for healthy washing of the washing machine according to any one of the above solutions, wherein the control method for the drainage check structure for healthy washing of the washing machine includes the following steps:
[0068] Step S101, when the washing container discharges liquid, the liquid in the washing container flows into the liquid discharge hole through the support assembly, and the liquid flowing into the liquid discharge hole causes the elastic check valve to switch to an elastic state under the action of gravity, and the elastic check valve disengages from the bottom end of the support assembly to dredge the liquid discharge hole, so that the liquid flows into the sewer pipe;
[0069] Step S102, when the washing container stops discharging liquid, the elastic check valve switches to the initial state under the action of the resilience force, and the elastic check valve fits against the bottom end of the support assembly to block the liquid discharge hole, so that the organisms in the sewer pipe are blocked outside the washing container.
[0070] The control method of the drainage check structure for the healthy washing of the washing machine provided by this application is applied to the drainage check structure for the healthy washing of the above-mentioned washing machine, and thus has all the beneficial effects of the above-mentioned drainage check structure for the healthy washing of the washing machine, which will not be elaborated here.
