Abstract
Description
Technical Field
[0001] This invention relates to the field of clothing processing equipment technology, specifically providing a shoe washing machine and a control method for the shoe washing machine. Background Technology
[0002] A shoe washing machine is a washing device that can clean shoes.
[0003] Currently, most shoe washing machines with significant cleaning effects are brush-type shoe washing machines. These machines are equipped with shoe washing brushes inside, and the brushes and shoes move relative to each other by moving the brushes and / or moving the shoes, so that the shoes are cleaned by the friction of the brush bristles.
[0004] In order to improve the efficiency and effect of shoe washing, detergent is usually added to the washing water. When the brush rubs the shoes, a large amount of cleaning foam containing detergent is generated in the washing water that has soaked the shoes, which effectively removes dirt from the shoe surface.
[0005] Existing shoe washing machines all have the vents on the lid. When water is added to the washing tub, the air inside the tub is expelled through the vents. During the shoe washing process, a large amount of foam is generated inside the tub. After the foam rises to the lid, it is easy to leak through the vents, posing a safety hazard.
[0006] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention
[0007] The present invention aims to solve the above-mentioned technical problem, namely, to solve the problem that the foam generated by the washing tub during the washing of shoes in existing shoe washing machines is prone to leakage through the vent holes, which poses a safety hazard.
[0008] In a first aspect, the present invention provides a shoe washing machine, the shoe washing machine comprising a housing, a washing tub disposed within the housing, and a tub lid for closing an opening at the top of the washing tub. The washing tub is provided with a vent hole and an exhaust channel, the vent hole communicating with the inside of the washing tub, the exhaust channel communicating with the vent hole, and the exhaust channel extending from the vent hole toward the top of the washing tub, the top end of the exhaust channel being open.
[0009] In the preferred embodiment of the above-mentioned shoe washing machine, a filter component is provided in the vent and / or the exhaust channel, and the filter component is used to filter foam.
[0010] In the preferred embodiment of the above-mentioned shoe washing machine, the filter component has water absorption properties; and / or
[0011] The vertical dimension of the vent is greater than its horizontal dimension.
[0012] In the preferred embodiment of the above-mentioned shoe washing machine, the inner wall of the exhaust channel is provided with a spike structure, which can puncture the foam.
[0013] In the preferred embodiment of the above-mentioned shoe washing machine, the exhaust channel spirals upward along the wall of the washing tub.
[0014] In the preferred embodiment of the shoe washing machine described above, the inner diameter of the exhaust channel gradually increases from the bottom end to the top end of the exhaust channel.
[0015] In the preferred embodiment of the above-mentioned shoe washing machine, the exhaust channel is formed on the outer wall of the washing tub; and / or
[0016] The exhaust passage is flat; and / or
[0017] The top of the exhaust channel extends to the top of the washing tub.
[0018] In the preferred embodiment of the shoe washing machine described above, the housing is equipped with a pull-out drawer, and the washing tub is disposed inside the drawer.
[0019] In a second aspect, the present invention also provides a control method for the above-mentioned shoe washing machine, the control method comprising:
[0020] When water is being added to the washing tub, the water level in the washing tub is obtained;
[0021] When the water level in the washing tub reaches the upper limit, stop adding water to the washing tub;
[0022] The upper limit water level is not higher than the lower edge of the vent hole.
[0023] In the preferred embodiment of the control method for the aforementioned shoe washing machine, the upper limit water level includes a first upper limit water level and a second upper limit water level, wherein the first upper limit water level is lower than the second upper limit water level, and the second upper limit water level is not higher than the lower edge of the vent hole.
[0024] During the washing stage, the step of "stopping water intake into the washing tub when the water level in the tub reaches the upper limit" specifically includes:
[0025] When the water level in the washing tub reaches the first upper limit water level, stop adding water to the washing tub;
[0026] During the rinsing stage, the step of "stopping water intake into the washing tub when the water level in the washing tub reaches the upper limit" specifically includes:
[0027] When the water level in the washing tub reaches the second upper limit water level, stop adding water to the washing tub.
[0028] By adopting the above technical solution, the shoe washing machine of the present invention no longer places the vent hole on the lid, but instead places it on the washing tub, and provides an exhaust channel on the washing tub that communicates with the vent hole. This helps prevent foam overflow and reduces safety hazards. Specifically, during the shoe washing process, if foam enters the vent hole, it needs to climb upwards along the exhaust channel. The inside of the exhaust channel is relatively narrow, and the foam will automatically break up during its ascent. After breaking up, the foam becomes liquid and will automatically flow back into the washing tub along the exhaust channel.
[0029] Furthermore, the shoe washing machine of the present invention provides a filter component in the vent holes and / or exhaust channels, which causes the foam to break as it passes through the filter component, thereby more effectively preventing foam overflow and further reducing safety hazards.
[0030] Furthermore, the shoe washing machine of the present invention can prevent the air vents from being completely blocked by the filter component by making the vertical dimension of the air vents larger than the horizontal dimension. Specifically, after the foam is filtered by the filter component, it becomes liquid and is absorbed by the filter component. After the filter component absorbs the liquid, its air permeability becomes poor or even cannot be breathed. By making the vertical dimension of the air vents larger than the horizontal dimension, the water absorbed by the filter component will accumulate in the lower part of the filter component, so that the upper part of the filter component remains breathable and the air vents are not completely blocked.
[0031] Furthermore, the shoe washing machine of the present invention provides a spiked structure on the inner wall of the exhaust channel, which punctures the foam upon contact with the spiked structure, thereby more effectively preventing foam overflow and further reducing safety hazards.
[0032] Furthermore, the shoe washing machine of the present invention, by setting the exhaust channel in a flat shape, helps to reduce the space occupied by the exhaust channel, so that the exhaust channel is only attached to the outer wall of the washing tub, avoiding excessive protrusion from the outer tub wall.
[0033] Furthermore, by gradually increasing the inner diameter of the exhaust channel, the shoe washing machine of the present invention can slow down the speed of foam rising, which helps the foam to break before it rises to the top of the exhaust channel, thereby better preventing foam overflow and further reducing safety hazards.
[0034] Furthermore, the shoe washing machine of the present invention extends the length of the exhaust channel by making the exhaust channel spiral upward along the wall of the washing tub, thereby more effectively preventing overflow and further reducing safety hazards.
[0035] Furthermore, the shoe washing machine of the present invention, by setting the exhaust channel on the outer wall of the washing tub, can avoid occupying the internal space of the washing tub, avoid affecting the rotation of the shoes in the washing tub, thus ensuring the washing effect of the shoes, and also avoid scratching the shoes and causing damage. It is also easy to process and avoids making the tub wall too thick.
[0036] Furthermore, the shoe washing machine of the present invention makes full use of vertical space by extending the exhaust channel from the vent hole all the way to the top of the washing tub, thereby maximizing the length of the exhaust channel and improving the anti-overflow foaming effect.
[0037] Furthermore, the shoe washing machine of the present invention obtains the water level in the washing tub when water is introduced into the washing tub, and stops introducing water into the washing tub when the water level in the washing tub reaches the upper limit water level. The upper limit water level is not higher than the vent hole, which can avoid water leakage and further improve the safety of the shoe washing machine. Attached Figure Description

[0048] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.
[0049] It should be noted that in the description of this invention, terms such as "upper," "lower," "top," and "bottom," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0050] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "set," "connect," and "install" should be interpreted broadly, for example, referring to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0051] As pointed out in the background art, existing shoe washing machines often suffer from foam leakage from the vent holes during washing, posing a safety hazard. This invention provides a shoe washing machine and its control method. By placing the vent holes on the wall of the washing tub and providing an exhaust channel communicating with the vent holes on the tub wall, with the exhaust channel extending towards the top of the washing tub, this method helps prevent foam overflow from the washing tub and reduces safety hazards.
[0052] Specifically, such as Figure 1 As shown, the shoe washing machine of the present invention includes a housing 1 and a washing tub 2 disposed inside the housing 1.
[0053] For example, the shoe washing machine of the present invention is a drawer-type shoe washing machine. The front of the box 1 has an opening, and the box 1 is provided with a pull-out drawer 11. The drawer 11 can be pulled out from the opening. The washing tub 2 is provided on the drawer 11. The top of the washing tub 2 has a loading and unloading opening. The user can put the shoes to be cleaned into the washing tub 2 through the loading and unloading opening, and can also take out the cleaned shoes from the washing tub 2 through the loading and unloading opening. The top of the washing tub 2 is also provided with a tub lid 3. When washing shoes, the tub lid 3 is used to close the loading and unloading opening. After washing the shoes, the drawer 11 is pulled out, and then the tub lid 3 is opened to take out the washed shoes from the washing tub 2.
[0054] In the first possible scenario, the washing tub 2 of the present invention is a single-tub structure, also known as a water tank. The washing tub 2 is rotatably disposed inside the housing 1. In the case where a drawer 11 is provided, the washing tub 2 is rotatably disposed inside the drawer 11. The tub wall of the washing tub 2 is well sealed so as to hold washing water and shoes. The washing tub 2 can be driven to rotate by a drive motor disposed below the bottom of the washing tub 2.
[0055] In the case of washing shoes, the washing tub 2 can agitate the washing water and shoes by rotating, or dehydrate the shoes. The interior of the washing tub 2 can also be equipped with other components that can directly or indirectly clean the shoes, such as a rotatable impeller at the bottom of the tub, or a shoe-washing brush 4 installed in the impeller or in a location other than the impeller inside the tub.
[0056] In the second possible scenario, the washing tub 2 of the present invention has a double-tub structure, comprising an outer tub and an inner tub. The outer tub is fixed inside the housing 1. If a drawer 11 is provided, the outer tub is fixedly installed inside the drawer 11. The inner tub is rotatably installed inside the outer tub. The outer tub can hold washing water, and shoes are placed in the inner tub. The inner tub has water passage holes distributed on its wall to allow washing water to enter and exit. The inner tub can be driven to rotate by a drive motor located below the bottom of the washing tub 2.
[0057] In shoe washing, the inner tub can agitate the washing water and shoes by rotating, or spin-dry the shoes. The inner tub can also contain other components that directly or indirectly clean the shoes, such as a rotatable impeller at the bottom of the inner tub, or a shoe-washing brush 4 located inside the impeller or in a position other than the impeller itself.
[0058] The shoe washing machine of the present invention further includes a water inlet mechanism (not shown in the figure) and a drainage mechanism (not shown in the figure). The water inlet mechanism is used to introduce water into the washing tub 2, and the drainage mechanism is used to discharge the washing water in the washing tub 2.
[0059] For example, the water inlet mechanism includes a water inlet pipe and a water inlet valve installed on the water inlet pipe. The water inlet end of the water inlet pipe is connected to a water source (e.g., a faucet), and the water outlet end of the water inlet pipe is connected to the washing tub 2. The water inlet valve is communicatively connected to the controller of the shoe washing machine. When water needs to be introduced into the washing tub 2, the controller controls the water inlet valve to open, and water from the water source flows along the water inlet pipe into the washing tub 2. When water does not need to be introduced into the washing tub 2, the controller controls the water inlet valve to close.
[0060] In addition, a spray component can be installed inside the washing tub 2 so that the water outlet of the water inlet pipe is connected to the spray component, that is, water is introduced by spraying.
[0061] For example, the drainage mechanism includes a drainage pump, a drainage pipe, and a drainage valve installed on the drainage pipe. The inlet of the drainage pump is connected to the washing tub 2, and the outlet of the drainage pump is connected to the drainage pipe. The drainage pipe extends to the outside of the housing 1. Both the drainage pump and the drainage valve are connected to the controller of the shoe washing machine. When it is necessary to drain the washing water in the washing tub 2, the drainage pump is started and the drainage valve is opened, and the washing water in the washing tub 2 is discharged along the drainage pipe. When drainage is not required, the drainage pump and the drainage valve are closed.
[0062] As can be seen from the background technology, existing shoe washing machines all have the vent hole located on the lid 3. When water is fed into the washing tub 2, the air inside the washing tub 2 is discharged through the vent hole 3. During the shoe washing process, a large amount of foam is generated inside the washing tub 2. After the foam rises to the lid 3, it is easy to leak from the vent hole 3, which poses a safety hazard.
[0063] To address the problem of overflowing foam in existing shoe washing machines, such as Figure 2 As shown, the washing tub 2 of the present invention is provided with a vent 21 and an exhaust channel 22. Figure 2 The two dashed lines in the figure show the exhaust channel 22. The vent 21 is connected to the inside of the washing tub 2, which refers to the washing chamber inside the washing tub 2. The exhaust channel 22 is connected to the vent 21, and the exhaust channel 22 extends from the vent 21 toward the top of the washing tub 2. The top of the exhaust channel 22 is open.
[0064] In other words, the shoe washing machine of the present invention no longer places the vent 21 on the lid 3, but places the vent 21 on the washing tub 2, and provides an exhaust channel 22 on the washing tub 2 that communicates with the vent 21. This helps to prevent overflow and reduce safety hazards.
[0065] Specifically, during the shoe cleaning process, if foam enters the vent 21, it needs to climb up along the exhaust channel 22. The inside of the exhaust channel 22 is relatively narrow, and the foam will automatically break up during the climbing process. After the foam breaks up, it becomes liquid and will automatically flow back into the washing tub 2 along the exhaust channel 22.
[0066] It should be noted that the present invention does not limit the distance between the vent hole 21 and the top of the washing tub 2. For example, those skilled in the art can set the distance between the vent hole 21 and the top of the washing tub 2 to 50mm, 70mm, 90mm, 100mm, 120mm or 150mm, etc., preferably 80mm to 120mm.
[0067] Furthermore, it should be noted that, in practical applications, those skilled in the art may place the exhaust channel 22 on the inner wall of the washing tub 2, or on the outer wall of the washing tub 2, or between the inner and outer walls of the washing tub 2, etc. Such adjustments and changes to the specific location of the exhaust channel 22 do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.
[0068] Preferably, such as Figure 2 As shown, the exhaust channel 22 of the present invention is formed on the outer wall of the washing tub 2.
[0069] Compared to placing the exhaust channel 22 on the inner wall of the washing tub 2, placing the exhaust channel 22 on the outer wall of the washing tub 2 can avoid occupying the internal space of the washing tub 2, avoid affecting the rotation of the shoes inside the washing tub 2, thus ensuring the washing effect of the shoes, and also avoid scratching the shoes and causing damage.
[0070] In addition, compared to placing the exhaust channel 22 between the inner and outer walls of the washing tub 2, placing the exhaust channel 22 on the outer wall of the washing tub 2 is not only easier to process, but also avoids making the tub wall of the washing tub 2 too thick.
[0071] It should be noted that, in practical applications, those skilled in the art can make the exhaust channel 22 extend vertically from the vent 21 toward the top of the washing tub 2, or they can make the exhaust channel 22 extend obliquely from the vent 21 toward the top of the washing tub 2, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.
[0072] Preferably, such as Figure 2 As shown, the exhaust channel 22 of the present invention spirals upward along the wall of the washing tub 2.
[0073] In other words, the exhaust channel 22 does not extend vertically, but extends spirally along the outer contour of the washing tub 2. Compared to making the exhaust channel 22 rise vertically, by making the exhaust channel 22 spiral upward along the tub wall of the washing tub 2, the length of the exhaust channel 22 can be extended, which is more conducive to preventing overflow and further reducing safety hazards.
[0074] Preferably, such as Figure 2 As shown, the top of the exhaust channel 22 of the present invention extends to the top of the washing tub 2.
[0075] In other words, the exhaust channel 22 extends from the vent 21 all the way to the top of the washing tub 2, making full use of the vertical space and maximizing the length of the exhaust channel 22, thus improving the anti-overflow foaming effect.
[0076] Preferably, such as Figure 2 As shown, the inner diameter of the exhaust channel 22 gradually increases from the bottom end to the top end of the exhaust channel 22.
[0077] By gradually increasing the inner diameter of the exhaust channel 22, the speed of foam rise can be slowed down, which helps the foam to burst before it reaches the top of the exhaust channel 22, thus better preventing foam overflow and further reducing safety hazards.
[0078] Preferably, such as Figure 2 As shown, the exhaust channel 22 of the present invention is flat.
[0079] By making the exhaust channel 22 flat, it is beneficial to reduce the space occupied by the exhaust channel 22, so that the exhaust channel 22 is only attached to the outer wall of the washing tub 2, avoiding excessive protrusion from the outer wall.
[0080] Preferably, the vent 21 and / or exhaust channel 22 of the present invention are provided with a filter element (not shown in the figure), which is used to filter foam.
[0081] By incorporating a filter element within the vent 21 and / or exhaust channel 22, the foam breaks as it passes through the filter element, thereby more effectively preventing foam overflow and further reducing safety hazards.
[0082] It should be noted that the filter component is breathable and will not block the vent 21 and exhaust channel 22.
[0083] It should be noted that, in practical applications, those skilled in the art can place the filter component inside the vent hole 21, or the filter component inside the exhaust channel 22, or even place the filter component in both the vent hole 21 and the exhaust channel 22, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.
[0084] Furthermore, it should be noted that the present invention does not limit the specific structural form of the filter component. For example, those skilled in the art can set the filter component as a filter screen, cotton cloth, or sponge, etc.
[0085] Preferably, the filter element of the present invention has water absorption properties.
[0086] Compared to other types of filter components, using water-absorbing filter components results in better foam filtration and is more effective in preventing foam overflow.
[0087] For example, the absorbent filter element can be a sponge or cotton cloth, etc.
[0088] Preferably, such as Figure 2 As shown, the vertical dimension of the vent 21 of the present invention is larger than the horizontal dimension.
[0089] By making the vertical dimension of the vent 21 larger than its horizontal dimension, the vent 21 can be prevented from being completely blocked by the filter element. Specifically, after the foam is filtered by the filter element, it becomes liquid and is absorbed by the filter element. After the filter element absorbs the liquid, its air permeability becomes poor or even becomes impossible to breathe. By making the vertical dimension of the vent 21 larger than its horizontal dimension, the water absorbed by the filter element will accumulate in the lower part of the filter element, keeping the upper part of the filter element breathable and preventing the vent 21 from being completely blocked.
[0090] For example, the vent 21 is rectangular, and the rectangular vent 21 extends in the vertical direction. The length of the vent 21 is preferably 50 to 60 mm, and the width of the vent 21 is preferably 15 to 20 mm.
[0091] It should be noted that the shape of the vent 21 is not limited to the rectangle mentioned above. For example, the vent 21 can also be set as an oblong or elliptical shape, etc.
[0092] Preferably, the inner wall of the exhaust channel 22 of the present invention is provided with a spike structure (not shown in the figure), which can puncture the foam.
[0093] By setting a spiked structure on the inner wall of the exhaust channel 22, the foam is punctured when it comes into contact with the spiked structure, which is more effective in preventing foam overflow and further reducing safety hazards.
[0094] Those skilled in the art can provide multiple spike structures on the inner wall of the exhaust channel 22, such that the multiple spike structures are spaced apart along the length of the exhaust channel 22.
[0095] The present invention also provides a control method for the above-mentioned shoe washing machine, such as... Figure 3 As shown, the control method of the present invention includes the following steps:
[0096] S100: When water is introduced into the washing tub 2, the water level in the washing tub 2 is obtained;
[0097] S200: When the water level in the washing tub 2 reaches the upper limit, stop adding water to the washing tub 2.
[0098] The upper limit water level is not higher than the lower edge of the vent 21, where the lower edge of the vent 21 refers to the position of the bottommost part of the vent 21.
[0099] For example, in step S100 above, water is introduced into the washing tub 2 by opening the water inlet mechanism. A water level sensor is provided in the washing tub 2 and is connected to the controller of the shoe washing machine so as to send the detected water level data to the controller. In step S200 above, when the water level in the washing tub 2 reaches the upper limit water level, the controller controls the water inlet mechanism to close and stops the water from entering the washing tub 2.
[0100] By ensuring that the upper limit water level does not exceed the lower edge of the vent 21, water leakage can be avoided, thereby further improving the safety of the shoe washing machine.
[0101] Preferably, such as Figure 2 As shown, the upper limit water level includes a first upper limit water level 51 and a second upper limit water level 52. The first upper limit water level 51 is lower than the second upper limit water level 52, and the second upper limit water level 52 is not higher than the lower edge of the vent 21.
[0102] During the washing stage, the step of "stopping water intake into the washing tub 2 when the water level in the washing tub 2 reaches the upper limit water level" specifically includes:
[0103] When the water level in the washing tub 2 reaches the first upper limit water level 51, stop adding water to the washing tub 2;
[0104] During the rinsing stage, the step of "stopping water intake into the washing tub 2 when the water level in the washing tub 2 reaches the upper limit" specifically includes:
[0105] When the water level in the washing tub 2 reaches the second upper limit water level 52, stop adding water to the washing tub 2.
[0106] In other words, the present invention sets different upper limit water levels for the washing and rinsing stages. The first upper limit water level 51 is the upper limit water level for washing, and the second upper limit water level 52 is the upper limit water level for rinsing. By making the upper limit water level for washing lower than the upper limit water level for rinsing, the washing tub 2 has more space to accommodate foam, which is more conducive to preventing foam overflow. Furthermore, by making the upper limit water level for rinsing higher than the upper limit water level for washing, more water can be introduced into the washing tub 2 during the rinsing stage, which is beneficial to improving the rinsing effect on shoes.
[0107] For example, such as Figure 2 As shown, the second upper limit water level 52 is exactly flush with the lower edge of the vent 21, and the first upper limit water level 51 is located below the second upper limit water level 52. The vertical distance between the two is preferably set to 50 to 100 mm.
[0108] It should be noted that the control method provided in this embodiment can be stored as a program in a computer-readable storage medium. This storage medium includes several instructions to cause a computer device (which may be a personal computer, server, or network device, etc.) or processor to execute some steps of the methods of the various embodiments of the present invention. The aforementioned storage medium includes various media capable of storing program code, such as a USB flash drive, a portable hard drive, a read-only memory (ROM), a random access memory (RAM), a magnetic disk, or an optical disk.
