DETAILED DESCRIPTION

[0031] 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 as needed to adapt to specific applications. For example, although the present application is described in conjunction with a pulsator washing machine, this is not restrictive. The washing device of the present invention can also be a drum washing machine, a shoe washing machine, a sock washing machine, an underwear washing machine, etc. Those skilled in the art can set the specific purpose of the washing device as needed, and all fall within the scope of protection of the present invention.

[0032] It should be noted that, in the description of the present invention, terms such as "upper", "lower", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element 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.

[0033] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation" and "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; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] like Figure 1 As shown, in order to solve the problems of poor dissolution effect and disinfection effect of the slow-release disinfection box of the existing washing machine, the washing device of the present invention includes a rotatable washing tub 1, a water channel component 2 and a slow-release medicine box 3, the water channel component 2 is connected to the inner wall of the washing tub 1 and surrounds a circulating water channel 5 with the inner wall of the washing tub 1, the washing tub 1 is provided with a water inlet for letting water into the circulating water channel 5, a disinfection spray port 21 is formed on the water channel component 2, the disinfection spray port 21 is connected to the circulating water channel 5, and the slow-release medicine box 3 is arranged in the disinfection spray port 21 to spray and disinfect the washing tub 1.

[0035] The advantage of the above arrangement is that when the user needs to disinfect the clothes or the inside of the washing device, after the washing water is filled into the washing tub 1, the washing water enters the circulating waterway 5 from the water inlet on the washing tub 1. When the washing tub 1 rotates, the washing water flows in the circulating waterway 5 under the action of a certain centrifugal force. When it reaches the disinfection spray port 21, the washing water continuously flushes the slow-release medicine box 3 to slowly release and dissolve the slow-release tablets 33 and spray the disinfected clothes from top to bottom. While improving the solubility of the slow-release tablets 33, the washing water circulates into the slow-release medicine box 3, which can make the drug concentration of the washing water in the washing tub 1 more uniform, and spraying the disinfected clothes from top to bottom makes the spray range larger, and the disinfectant can fully contact the clothes, thereby improving the disinfection effect. In addition, since the washing water circulates into the circulating waterway 5 for flushing, the cleanliness of the circulating waterway 5 can be kept.

[0036] Reference Figure 1 In a possible embodiment, the washing device includes a rotatable washing bucket 1, a water channel component 2 and a slow-release medicine box 3. A balance ring 4 is provided on the top of the washing bucket 1. The water channel component 2 is connected to the inner wall of the washing bucket 1 and is surrounded by the inner wall of the washing bucket 1 to form a circulating water channel 5. An avoidance portion is provided on the balance ring 4. The inner wall of the washing bucket 1, the avoidance portion of the balance ring 4 and the water channel component 2 are jointly surrounded to form a disinfection spray port 21, so that the position of the disinfection spray port 21 is located above the water channel component 2. The higher the position of the disinfection spray port 21, the larger the spraying area when the washing water with disinfectant is sprayed from top to bottom onto the clothes, the higher the intensity, and the better the disinfection effect. The spraying water can also speed up the speed at which the floating clothes in the washing bucket 1 are immersed in the water, such as down jackets, etc.

[0037] Continue to refer to Figure 1 and Figure 2 The washing device further includes a one-way valve 6 and a spray nozzle 7. A washing spray port 22 connected to the circulating waterway 5 is provided on the waterway assembly 2. The washing spray port 22 is located below the disinfection spray port 21. The one-way valve 6 is provided between the washing spray port 22 and the disinfection spray port 21. The one-way valve 6 is provided to be able to open in the direction of the disinfection spray port 21. Optionally, the number of washing spray ports 22 is six, which are sequentially provided on the waterway assembly 2 from top to bottom. However, it should be noted that the number of washing spray ports 22 can also be one, two, three, four, etc. Those skilled in the art can set the number of washing spray ports 22 as needed, and all fall within the protection scope of the present invention.

[0038] Next refer to Figure 2, the spray nozzle 7 is arranged in the disinfection spray port 21, and the slow-release medicine box 3 is arranged in the spray nozzle 7. Optionally, the slow-release medicine box 3 is arranged above the spray nozzle 7, and there is a water flow buffer space below the slow-release medicine box 3, part of the water flow enters the slow-release medicine box 3 above, and the other part flows out from the water flow buffer space below the slow-release medicine box 3, so as to avoid the water flow gathering at the slow-release medicine box 3 and affecting the spraying effect, and can also provide certain protection for the slow-release tablets 33 to prevent the slow-release tablets 33 from being damaged due to excessive water flow impact. Further, a clamping groove is arranged on the spray nozzle 7, and the slow-release medicine box 3 is clamped on the clamping groove to realize the limiting and installation of the slow-release tablets 33, so as to facilitate the user to take out the slow-release medicine box 3, and the assembly process is simpler and convenient for the subsequent replacement of the medicine box, and the user can also observe the slow-release medicine box 3 at the spray nozzle 7.

[0039] The washing water enters the disinfection spray port 21 through the water inlet and the circulating water channel 5 on the washing tub 1. The water circulates and flushes the slow-release medicine box 3 to slowly release and dissolve the slow-release tablets 33, which are then sprayed onto the clothes from the spray nozzle 7, which can further increase the spray area and spray intensity and improve the disinfection effect.

[0040] Reference Figure 1 and Figure 2 Furthermore, a washing spray port 22 for spraying washing water into the washing tub 1 is provided on the water channel assembly 2. The washing spray port 22 is provided below the disinfection spray port 21. The one-way valve 6 is provided between the washing spray port 22 and the disinfection spray port 21. The one-way valve 6 is only opened in the direction of the disinfection spray port 21. When the user needs to disinfect the clothes, the rotation speed of the washing tub 1 is relatively high. Under the action of the large centrifugal force, the flow velocity and pressure of the water flow in the circulating water channel 5 are high, so that a part of the water flow can open the one-way valve 6 and enter the disinfection spray port 21 to disinfect the clothes, and the other part of the water flow can be sprayed on the clothes from the washing spray port 22, thereby achieving a double spraying effect of strengthening disinfection and washing.

[0041] On the contrary, when the user does not need to disinfect the clothes, the rotation speed of the washing tub 1 is low. Under the action of smaller centrifugal force, the flow rate of water in the circulating waterway 5 is low and the pressure is small, so that the water flow pressure is insufficient to open the one-way valve 6, and the washing water does not enter the slow-release medicine box 3. The washing water can only be sprayed onto the clothes through the washing spray port 22 to improve the cleaning effect of the clothes.

[0042] Therefore, the washing device of the present invention can control the washing device to disinfect or not disinfect clothes by adjusting the rotation speed of the washing barrel 1. It not only has a simple structure, low assembly cost and better disinfection effect, but also can achieve a double spray effect of disinfection and enhanced washing. Compared with the transient flushing of the sustained-release medicine box 3 to dissolve the sustained-release tablets 33 when the washing device is filled with water, the present invention can dissolve the sustained-release tablets 33 more easily, and on this basis, the density of the sustained-release tablets 33 can be increased, thereby preventing its small particles from scattering and preventing the disinfectant powder from remaining on the clothes.

[0043] Optionally, the washing device is a pulsator washing machine, and the washing tub 1 includes an inner drum 11 and an outer drum 12, the inner drum 11 is rotatably arranged in the outer drum 12, the inner drum 11 is provided with a water inlet for intake of water into the circulating water channel 5, a rotatable pulsator is provided at the bottom of the inner drum 11, a balance ring 4 is provided at the top of the inner drum 11, the water channel assembly 2 is connected to the inner wall of the inner drum 11 and is arranged with the inner wall of the inner drum 11 to form a circulating water channel 5, the balance ring 4 is provided with an avoidance portion 41, and the inner wall of the inner drum 11, the balance ring avoidance portion 41 and the water channel assembly 2 are jointly arranged to form a disinfection spray port 21.

[0044] Reference Figures 3 to 5 , further, the sustained-release medicine box 3 includes a box body 31, a cover plate 32, a sustained-release tablet 33, a filter screen 35 and a filter screen frame, the box body 31 is provided with an opening, the cover plate 32 is arranged on the box body 31 to close the opening, and optionally, the cover plate 32 is ultrasonically welded to the box body 31. The two ends of the box body 31 are respectively provided with a water inlet hole 311 and a sustained-release hole 312, two limiting plates 34 are arranged between the water inlet hole 311 and the sustained-release hole 312, the number of the sustained-release tablets 33 is at least two, each sustained-release tablet 33 includes a disinfectant component, and a plurality of sustained-release tablets 33 are arranged as a combination of multiple disinfectant components, thereby improving the disinfection effect. Further, the sustained-release tablet 33 is arranged between the two limiting plates 34, a sustained-release gap 36 is provided between the cover plate 32 and the top of the limiting plate 34, and a soluble coating film is provided on the outside of the sustained-release tablet 33. Optionally, the sustained-release tablets 33 are cross-shaped, and each group of sustained-release tablets 33 is limited and damped by a limiting plate 34 to avoid breakage caused by shaking and vibration, and to avoid a series of problems such as abnormal sounds. However, it should also be noted that the cover plate 32 is detachably arranged on the box body 31 to open and close the opening of the box body 31, so that the sustained-release tablets 33 can be easily replaced. Optionally, the cover plate 32 and the box body 31 are connected by a card slot buckle or bolt connection, etc. Those skilled in the art can set the connection method between the cover plate 32 and the box body 31 as needed, and all fall within the protection scope of the present invention.

[0045] Furthermore, the filter screen 35 is arranged on the filter screen frame, and the filter frame is respectively arranged at the water inlet hole 311 and the slow-release hole 312. The washing water enters the box body 31 through the water inlet hole 311, and then flows through the filter screen 35-slow-release gap 36-slow-release tablet 33-slow-release gap 36-filter screen 35-slow-release hole 312. After passing through multiple obstacles, the water flows out from the slow-release hole 312, which can better adapt to the impact of strong water flow and prevent damage and abnormal noise.

[0046] Optionally, the filter frame and the filter 35 are integrally formed, for example, the filter frame is made of polypropylene (PP) material, the filter 35 is made of polymer materials such as nylon or polypropylene mesh, and the mesh number of the filter 35 is between 30-300, which can buffer and reduce shock to prevent the tablets from being damaged, and the damaged particles can also be intercepted in the box body 31 to prevent leakage. Of course, the medicine box 3 can also be provided with no filter frame but directly set the filter 35 at the water inlet hole 311 and the slow-release hole 312. Those skilled in the art can set it by themselves according to their needs, and all fall within the protection scope of the present invention.

[0047] The sustained-release tablet 33 of the present invention is a substance such as hypochlorous acid tablets, bromochlorohydantoin, dichlorohydantoin, etc. The sustained-release slightly acidic hypochlorous acid water is a small molecule water, and its effective ingredient is hypochlorous acid (HClO), and the concentration level is 0.1-500ppm, optionally 0.2-200ppm, and preferably 0.5-5ppm. Hypochlorous acid is an immune substance released by neutrophils in the human body to phagocytize and kill pathogens. Now, low-concentration slightly acidic hypochlorous acid water can be generated by artificial technology. For the human body, hypochlorous acid is a safer and more effective disinfection product than sodium hypochlorite. The hypochlorous acid in slightly acidic hypochlorous acid water exists in the form of molecules that do not carry an electric charge, while the surface of bacteria carries a negative charge. Like a magnet, molecules with the same charge will repel each other. For example, negatively charged hypochlorite ions (ClO-) will repel each other from the surface of bacteria, so the ability of hypochlorite ions to kill bacteria is relatively poor. Hypochlorous acid can easily penetrate the bacterial cell wall, oxidize the cell wall to kill the bacteria, or enter through the cell wall and destroy important components in the bacteria.

[0048] The bactericidal ability of hypochlorous acid is 80 times that of hypochlorite ion. In the process of sterilization and virus killing, hypochlorous acid can not only act on cell walls and virus shells, but also because hypochlorous acid molecules are small and uncharged, they can penetrate into the bodies of pathogens and undergo oxidation reactions with the bacteria's body proteins, nucleic acids, enzymes, etc., leading to the death of pathogenic microorganisms. Studies have shown that when hypochlorous acid is close to neutral (pH 5.0-6.5), the effective chlorine exists almost entirely in the form of hypochlorous acid molecules.

[0049] Of course, the components of the sustained-release tablets 33 can also be silver ion glass, nanosilver, etc. Although the disinfectant component of each sustained-release tablet 33 can be any one of hypochlorous acid, bromochlorohydrin, dichlorohydrin, silver ion glass and nanosilver, those skilled in the art can also set the specific components of the sustained-release tablets 33 as needed. The present invention does not impose any limitation on this, and all of them fall within the protection scope of the present invention.

[0050] As stated in the first paragraph of this section, the above implementation mode is only used to illustrate the principles of the present invention and is not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above structure so that the present invention can be applied to more specific application scenarios.

[0051] In addition, the present invention also provides a control method for a washing device, wherein the washing device is the washing device described in any of the above embodiments;

[0052] The control method of the washing device mainly includes:

[0053] Step: receiving an instruction to run a disinfection and washing program;

[0054] Steps: When running the washing and / or rinsing program in the disinfection washing program, the speed of the washing tub is controlled to be N1, so that the water in the circulating water channel is sprayed out from the disinfection spray port.

[0055] The user selects a washing program. If the user selects a disinfection washing program, it means that the user needs to disinfect the clothes. The clothes can be disinfected during washing or rinsing. During washing or rinsing, the speed of the washing tub 1 is controlled to be N1. The washing water enters the circulating water channel 5 under the action of centrifugal force and enters the disinfection spray port 21 to flush the slow-release medicine box 3 to dissolve the disinfectant, so as to spray disinfectant onto the clothes in the washing tub 1.

[0056] Specifically, the washing device includes a rotatable washing bucket 1, a water channel assembly 2 and a slow-release medicine box 3. The water channel assembly 2 is connected to the inner wall of the washing bucket 1 and a circulating water channel 5 is formed with the inner wall of the washing bucket 1. A disinfection spray port 21 is formed on the water channel assembly 2, and the disinfection spray port 21 is connected to the circulating water channel 5. The slow-release medicine box 3 is arranged in the disinfection spray port 21; a washing spray port 22 connected to the circulating water channel 5 is arranged on the water channel assembly 2, and the washing spray port 22 is located below the disinfection spray port 21; the washing device also includes a one-way valve 6, which is arranged between the washing spray port 22 and the disinfection spray port 21, and the one-way valve 6 opens in the direction of the disinfection spray port 21;

[0057] The control method of the washing device specifically includes:

[0058] Steps: Turn on the washing device;

[0059] Step: receiving an instruction to run a disinfection and washing program;

[0060] Step: When running the washing and / or rinsing program in the disinfection washing program, the speed of the washing tub is controlled to be N1, so that the water flow in the circulating water channel can open the one-way valve;

[0061] Step: receiving an instruction to run a normal washing program;

[0062] Steps: When running the washing and / or rinsing program in the normal washing program, the speed of the washing tub is controlled to be N2, and N2 is less than N1, so that the water flow in the circulating water channel cannot open the one-way valve.

[0063] After turning on the washing device, the user selects a washing program. If the user selects a disinfection washing program, it means that the user needs to disinfect the clothes. The user can disinfect the clothes during washing or rinsing. Then, during washing or rinsing, the rotation speed of the washing tub 1 is controlled to be N1, and the washing water enters the circulating waterway 5 under the action of centrifugal force, and a part of the water pressure in the circulating waterway 5 can open the one-way valve 6. The water flows into the slow-release medicine box 3 and rinses it so that the medicine is slowly released in the water flow, and is sprayed from top to bottom into the washing tub 1 through the disinfection spray port 21 to spray and disinfect the clothes. The other part of the water does not pass through the one-way valve 6, but is directly sprayed onto the clothes from the washing spray port 22 on the waterway component 2 to enhance the washing or rinsing, so as to achieve the dual spraying effect of enhanced disinfection and washing.

[0064] On the contrary, if the user selects a normal washing program, that is, there is no need to disinfect the clothes during washing or rinsing, then the speed of the washing tub 1 is controlled to N2 during washing or rinsing. N2 is less than N1, and the water flow cannot open the one-way valve 6, and thus cannot enter the disinfection spray port 21, and then all the water is sprayed into the washing tub 1 from the washing spray port 22.

[0065] It should be noted that disinfecting clothes during washing or rinsing can save water and disinfection time compared to running a separate disinfection program separately, but disinfecting clothes during washing or rinsing does not limit the disinfection program in any way. Those skilled in the art can also run a separate disinfection program after washing and rinsing. The separate disinfection program is to fill water into the washing tub 1, and then rotate the washing tub 1 to disinfect the clothes, which falls within the protection scope of the present invention. In addition, the control method can also be set to disinfect clothes during both washing and rinsing. Those skilled in the art can set it according to their needs, and it falls within the protection scope of the present invention.

[0066] 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.
