Description

Technical Field

[0001] The present invention belongs to the technical field of washing machines and related cleaning technologies, and specifically provides a shoe washing machine. Background Art

[0002] In the process of social development, people's living standards have been continuously improved, and the use of washing machines has also been popularized. A washing machine is an electrical appliance that converts electrical energy into mechanical motion to wash clothes. A washing machine mainly consists of components such as a cabinet, a washing and dehydration tub, a transmission system, and a control system. During use, clothes, bedding, etc. are placed in the washing and dehydration tub, and laundry detergent or washing powder is added. Starting the power supply motor can drive the motor shaft to rotate, and the motor shaft further drives the agitator to rotate. By the rotation of the agitator, the rotation of the washing and dehydration tub is driven to achieve operations such as friction, tumbling, and flushing between the items to be washed and water, and to wash away the dirt on the items to be washed. With the continuous change of user needs, the functional requirements for washing machines are also constantly improving, and it is no longer limited to just washing clothes.

[0003] With the acceleration of people's living rhythm, the demand for shoe washing is becoming increasingly urgent. When washing shoes only by hand with a shoe brush, it takes a lot of time, and the stains on the shoes are usually difficult to remove. Especially for sports shoes and casual shoes, there are a lot of sweat stains and stains on the surface. If washed by hand, it is time-consuming and laborious, with low efficiency, and often difficult to clean the shoes thoroughly, and cannot achieve an ideal cleaning effect. Against this background, shoe washing machines have emerged. However, many existing shoe washing machines are improved by adding modules on the basis of existing agitator washing machines. According to the washing principle of the washing machine, a shoe washing module is added to the inner tub of the washing machine to achieve a targeted washing process for shoes. For example, a vertically protruding rotatable cylinder is added in the middle of the inner tub of the washing machine, and then a brush is added. Through the contact and friction between the brush and the shoe surface, and under the combined action of water flow and laundry detergent or washing powder, the purpose of shoe washing is achieved. However, in actual washing, due to the high hardness of shoes, they are not easily deformed, and their sizes are irregular, resulting in problems such as easy shoe jamming, excessive friction, and washing the shoes out of shape during the washing process.

[0004] Correspondingly, there is a need in the art for a new shoe washing machine to solve the problems of easy shoe jamming and excessive friction during the existing shoe washing process. Summary of the Invention

[0005] To solve the above problems in the prior art, that is, to solve the problems that shoes are prone to jamming, excessive friction, and easy damage during the shoe washing process, the present invention provides a shoe washing machine, including a base body and a wave wheel. The base body is connected to the wave wheel. The area of the base body gradually decreases from the cross-section close to the wave wheel to the cross-section far from the wave wheel. A brush-like structure is provided on the surface of the base body.

[0006] In the preferred technical solution of the above shoe washing machine, the base body is a hemispherical structure.

[0007] In the preferred technical solution of the above shoe washing machine, a hollow barrel is provided at the center of the base body, and a connection hole is opened at the bottom of the barrel of the hollow barrel.

[0008] In the preferred technical solution of the above shoe washing machine, a clamping flange is provided around the base body.

[0009] In the preferred technical solution of the above shoe washing machine, the base body is formed by splicing two quarter spheres and is connected through a U-shaped groove. The wall thickness of the U-shaped groove is smaller than the wall thickness of the quarter sphere.

[0010] In the preferred technical solution of the above shoe washing machine, the brush-like structure is detachably connected to the base body.

[0011] In the preferred technical solution of the above shoe washing machine, the brush-like structure includes a covering layer and a plurality of bristles. The bristles are cylindrical and are provided on the covering layer.

[0012] In the preferred technical solution of the above shoe washing machine, the base body is provided at the center of the wave wheel.

[0013] In the preferred technical solution of the above shoe washing machine, there are a plurality of base bodies, and the plurality of base bodies are evenly distributed in a ring along the center of the wave wheel.

[0014] In the preferred technical solution of the above shoe washing machine, the base body is a frustum of a cone or a trapezoidal frustum.

[0015] Those skilled in the art can understand that in the technical solution of the present invention, a shoe washing machine is provided, including a base body and a wave wheel. The base body is connected to the wave wheel. The area of the base body gradually decreases from the cross-section close to the wave wheel to the cross-section far from the wave wheel. A brush-like structure is provided on the surface of the base body.

[0016] Through the above setting method, the base body is connected to the agitator. During the washing process, the base body rotates with the agitator. The surface of the base body is provided with a brush-like structure. During the process of the base body rotating with the agitator, the brush-like structure contacts and rubs against the shoes. Under the action of water flow and laundry detergent or washing powder, effective washing of the shoes is achieved. The area of the base body gradually decreases from the cross-section close to the agitator to the cross-section far from the agitator. That is to say, a gradually expanding space with an upward opening is formed between the base body and the side wall of the inner barrel of the washing machine, so that the shoe washing machine of the present invention can further avoid the situation of shoe jamming and excessive friction during the shoe washing process, which may damage the shoes.

[0017] Those skilled in the art can understand that shoes, especially sports shoes and casual shoes, have a fixed shape and are not in the shape of a regular circle. Their surfaces are relatively hard, and some shoes are relatively large in size. During the process of using a shoe washing machine for washing, it is very likely that the shoes will get jammed, and the shoes will rub against the inner barrel wall of the shoe washing machine and other components inside the inner barrel too much, damaging the shoes. Therefore, in the preferred technical solution of the present invention, a base body is provided inside the shoe washing machine. The area of the base body gradually decreases from the cross-section close to the agitator to the cross-section far from the agitator. Preferably, the base body is a hemispherical three-dimensional structure. A brush-like structure is provided on the base body, and the base body is connected to the agitator. During the shoe washing process, the agitator drives the base body to rotate. The brush-like structure contacts and rubs against the shoes, and effective washing of the shoes is achieved under the combined action of water flow and laundry detergent or washing powder. The brush-like structure includes a covering layer and bristles. The bristles are arranged on the covering layer. A clamping flange is arranged around the base body. The covering layer is detachably connected to the base body. Preferably, the covering layer is made of silicone material. The covering layer is sleeved on the base body and fixed by the clamping flange on the base body. According to different shoe conditions, the corresponding covering layer and bristle materials can be replaced to meet the washing requirements of different types of shoes. Compared with a shoe washing machine with a cylindrical or similar-shaped brush rod arranged at the center of the agitator, the shoe washing machine of this solution forms a gradually expanding space with an upward opening between the hemispherical base body and the inner barrel wall, which can effectively avoid shoe jamming during the washing process and the problem of shoe damage caused by excessive friction. Compared with a shoe washing machine that fixes the shoes on a bracket for washing, the shoe washing machine of this solution has a simpler structure, stronger operability during the washing process, and the covering layer is detachable and can be replaced according to the needs during actual use. Corresponding bristles are used for washing according to the materials and washing requirements of different shoes, further meeting the diversified washing requirements.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0026] First, refer to Figure 1 , and describe the shoe washing machine of the present invention. Among them, Figure 1 This is a schematic diagram of a shoe washing machine provided by an embodiment of the present invention.

[0027] AsFigure 1 As shown, to solve the problems of easy jamming and excessive friction in existing shoe washing machines, the shoe washing machine of the present invention includes a base body 4 and a wave wheel 3. The base body 4 is connected to the wave wheel 3. The area of the base body 4 gradually decreases from the cross-section close to the wave wheel 3 to the cross-section far from the wave wheel 3. A brush-like structure 41 is provided on the surface of the base body 4.

[0028] The advantages of the above setting method are as follows: An inner barrel 2 is provided in the outer barrel 1 of the shoe washing machine of this solution. A wave wheel 3, a base body 4, and a motor 5 are also provided in the inner barrel 2. The base body 4 is connected to the wave wheel 3. The wave wheel 3 drives the base body 4 to rotate under the action of the motor 5. The area of the base body 4 gradually decreases from the cross-section close to the wave wheel 3 to the cross-section far from the wave wheel 3. A space 6 with an upwardly opening gradually increasing is formed between the base body 4 and the inner barrel 2 of the shoe washing machine. During the shoe washing process, the situation of shoe jamming will not occur. Further, there is no situation of excessive friction and damage to the shoes. A brush-like structure 41 is provided on the surface of the base body 4. The base body 4 plays a role of a skeleton. In a preferred embodiment, the base body 4 is made of a hard material such as plastic. The hard plastic effectively supports the brush-like structure 41 to ensure that during the washing process, the brush-like structure 41 makes effective contact and friction with the shoes. The brush-like structure 41 is provided on the base body 4. During the washing process, the base body 4 rotates with the wave wheel 3. During the rotation process of the base body 4, its brush-like structure 41 contacts and frictions with the shoes, and under the combined action of water flow and laundry detergent or washing powder, the effect of cleaning the shoes is achieved.

[0029] The following will refer to Figure 1 and Figure 2 , and describe the shoe washing machine of the present invention in detail. Among them, Figure 2 is a partial schematic view of a shoe washing machine provided by an embodiment of the present invention.

[0030] In a possible embodiment, the base body 4 is a hemispherical structure.

[0031] The advantages of the above setting method are as follows: The base body 4 is set as a hemispherical structure. The structure of the base body 4 is more regular. The surface of the base body 4 is a smooth arc surface. During the washing process, situations such as violent impacts are not likely to occur, and it can also achieve more sufficient contact with the shoe surface to ensure the washing effect. The hemispherical structure and the side edge of the inner barrel 2 form a space 6 with an upwardly opening gradually increasing. During the process of the shoes reversing and rubbing in this space, the situation of jamming due to the large size of the shoes will not occur, and at the same time, the situation of damage to the shoes due to excessive friction will not occur.

[0032] In a possible embodiment, a hollow barrel is provided at the center of the base body 4, and a connection hole is opened at the bottom of the hollow barrel.

[0033] The advantages of the above setting method are as follows: A hollow barrel-shaped structure is provided at the center of the base body 4, and a connection hole is provided at the bottom of the barrel-shaped structure, and this connection hole can be tightly connected to the agitator 3. During the washing process, the base body 4 can rotate synchronously with the agitator 3. Preferably, a through hole is provided in the middle of the base body 4, and the bottom end of the through hole is inwardly recessed to form a step, and the radius of the through hole decreases. The agitator screw 31 can be connected through the through hole and the through hole on the agitator 3, and further tightly connected to the screw hole on the motor shaft 51 in place, so as to realize the tight connection among the base body 4, the agitator 3, and the motor shaft 51. The motor 5 drives the agitator 3 and the base body 4 to rotate through the motor shaft 51, and the agitator 3 rotates synchronously with the base body 4. At the same time, under the combined action of water flow and laundry detergent or washing powder, the purpose of shoe washing is achieved.

[0034] In a possible implementation manner, the brush-shaped structure 41 is detachably connected to the base body 4.

[0035] The advantages of the above setting method are as follows: The brush-shaped structure 41 is detachable. During use, the brush-shaped structure 41 can be selectively replaced according to the type, material, characteristics, and washing requirements of the shoes, etc., to realize the personalized washing process of the shoes.

[0036] In a possible implementation manner, the brush-shaped structure 41 includes a covering layer 411 and a plurality of bristles 412. The bristles 412 are cylindrical, and the bristles 412 are provided on the covering layer 411.

[0037] The advantages of the above setting method are as follows: A covering structure is provided on the surface of the base body 4. Preferably, this covering structure can use a silicone material, and a bristle 412 structure is provided on the covering layer 411. In a possible implementation manner, this bristle 412 structure is an elongated cylindrical soft bristle 412 made of silicone. The bristles 412 are evenly distributed on the base body 4. On the basis of ensuring the shoe cleaning effect, this soft bristle 412 causes less damage to the shoes. Further, this bristle 412 structure can be integrally formed with the covering layer 411. In another possible implementation manner, the bristle 412 structure is implanted on the covering layer 411, and its material can be a silicone material or other materials. During the shoe cleaning process, the bristles 412 come into contact with the shoes and generate friction, which can achieve the effect of shoe cleaning. Further, the bristle 412 structure is not limited to the elongated cylindrical bristles 412, and can be short and thick protrusions, or any other shape that can come into contact with the shoe surface and perform friction to achieve the washing effect.

[0038] Accordingly, the appropriate bristles 412 can be selected according to the type, material, characteristics, and washing requirements of the shoes. In a possible implementation, the bristles 412 are made of polypropylene. This material of bristles 412 has strong moisture absorption resistance, acid and alkali corrosion resistance, and solubility resistance. The polypropylene material hardly absorbs water, does not react with the vast majority of chemicals, and at the same time, the polypropylene material also has a lower cost and is more practical. This material of bristles 412 is more suitable for the washing process of ordinary shoes. In another implementation, the material of the bristles 412 is pig bristles. This material is elastic and not easily deformed, is easier to use in a humid environment, and is not affected by hot and cold environments. It is more suitable for the washing process of sports and casual shoes. In another implementation, the material of the bristles 412 is horsehair. Horsehair is soft and elastic, and is more suitable for the washing process of leather and similar materials of shoes. At the same time, the brush-like structure 41 is detachable from the base body 4, which can also make it more convenient for the disassembly, replacement, and cleaning of the brush-like structure 41.

[0039] In a possible implementation, a clamping flange 42 is provided around the base body 4.

[0040] The advantage of the above setting method is that: since the covering layer 411 is a soft structure and has a certain elasticity, it can be sleeved on the base body 4 through its own elastic deformation. In order to prevent the covering layer 411 from slipping off, a clamping flange 42 is provided around the bottom of the base body 4. After the covering layer 411 is sleeved on the base body 4, the edge of the covering layer 411 can be sleeved on the clamping flange 42 and effectively connected to the clamping flange 42 through contraction, preventing the covering layer 411 from slipping off during use and affecting the use effect.

[0041] In a possible implementation, as Figure 2 shown, the base body 4 is formed by splicing two quarter spheres 43 and is connected by a U-shaped groove 44. The wall thickness of the U-shaped groove 44 is smaller than the wall thickness of the quarter sphere 43.

[0042] The advantage of the above setting method is that: the base body 4 is formed by splicing two quarter spheres 43, and the structure is simpler. The two quarter spheres 43 are connected by a U-shaped groove 44, which can realize the effective fixation and connection of the two quarter spheres 43. The wall thickness of the U-shaped groove 44 is smaller than the wall thickness of the quarter sphere 43. After a force acts on the outer wall of the quarter sphere 43, due to the wall thickness of the U-shaped groove 44 being smaller than the wall thickness of the quarter sphere 43, under the action of the force, the U-shaped groove 44 can produce a certain degree of deformation pointing to the middle position of the U-shaped groove 44. In this way, the two quarter spheres 43 have a certain elasticity in the direction towards the U-shaped groove 44, which can further prevent the situation of shoe jamming caused by the large size of the shoes during the shoe washing process, and effectively solve the problem of excessive shoe friction and damage to the shoes.

[0043] In a possible implementation, the base body 4 is disposed at the center of the agitator 3.

[0044] The advantages of the above setting method are as follows: The base body 4 is arranged at the center of the agitator 3, and the structure is simpler. The base body 4 rotates synchronously with the agitator 3. Under the combined action of water flow and laundry detergent or washing powder, the effect of shoe cleaning is achieved. In a possible implementation, the agitator 3 and the base body 4 are integrally connected, and the connection between the base body 4 and the agitator 3 can be realized without additional connection structures, and the overall structure is simpler. In another possible implementation, the agitator 3 is connected to the base body 4 by a fastening method. Through holes are provided on the base body 4, and the through holes on the base body 4 correspond to the through holes on the agitator 3. Corresponding holes are also provided on the corresponding motor shaft 51. The through holes of the base body 4, the through holes on the agitator 3, and the holes on the motor shaft 51 are sequentially fastened and connected by the agitator screw 31, so as to effectively fix the agitator 3 and the base body 4, and drive by the motor 5, realize rotation at a corresponding frequency, and cooperate with the combined action of water flow and laundry detergent or washing powder, the purpose of washing shoes can be achieved. In this setting method, the base body 4 can be disassembled. When not in use or when washing other items, the base body 4 can be disassembled, and the agitator 3 can be directly used for washing, or cooperate with other modules for washing, realizing multi-functional use of one machine, and meeting diverse washing needs.

[0045] In a possible implementation, there are multiple base bodies 4, and the multiple base bodies 4 are evenly distributed in a ring along the center of the agitator 3.

[0046] The advantages of the above setting method are as follows: Multiple base bodies 4 are provided in the inner tub 2 of the washing machine, and the base bodies 4 are evenly distributed around the agitator 3. The multiple base bodies 4 rotate driven by the agitator 3, and the multiple base bodies 4 work simultaneously. The overall area of the covering layer 411 with bristles 412 is larger, and the contact area with the shoes also increases. At the same time, the cleaning process of more shoes can be realized, and the overall cleaning efficiency is higher.

[0047] In a possible implementation, the base body 4 is a frustum of a cone or a frustum of a pyramid.

[0048] The advantages of the above setting method are as follows: The base body 4 is a frustum of a cone or a frustum of a pyramid, and a space 6 with an upwardly opening gradually increasing is presented between the frustum of a cone or a frustum of a pyramid and the side wall of the inner tub 2, which can ensure that during the shoe cleaning process, the shoes will not get stuck due to too large size or other situations, and can also effectively avoid the situation that the shoes are damaged due to excessive friction. At the same time, diverse selections of the base body 4 are also given to better adapt to different application environments and scenarios.

[0049] In particular, the substrate 4 structure in the present invention can be applicable to different scenarios, and the covering layer 411 structure in the present invention can be applicable to different substrate 4 shapes. Those skilled in the art can make corresponding adjustments according to needs. For example, the technical solution of the present invention can be applied to the washing of shoes, and can also be applied to other similar washing devices, such as the washing of toys, the washing of fruits and melons, etc.

[0050] To sum up, the shoe washing machine of the present invention solves the problems such as jamming of shoes during the washing process and excessive wear of shoes caused by excessive friction by arranging the substrate 4 on the wave wheel 3. Specifically, the shoe washing machine of the present invention includes a wave wheel 3 and a substrate 4. The substrate 4 is connected to the wave wheel 3. The area of the substrate 4 gradually decreases from the cross-section close to the wave wheel 3 to the cross-section far from the wave wheel 3. A brush-like structure 41 is arranged on the surface of the substrate 4. The substrate 4 and the inner wall of the inner barrel 2 form a space 6 with an upwardly increasing opening. During the shoe washing process, it can effectively avoid the problem of shoe jamming caused by insufficient space between the inner wall of the inner barrel 2 and the brush due to the oversized shoes, and further avoid the problem of excessive wear of the shoes caused by excessive friction between the shoes and the brush and the inner wall of the inner barrel 2.

[0051] It should be noted that the above embodiments are only used to illustrate the principle of the present invention and are not intended to limit the protection scope of the present invention. Without departing from the principle 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.

[0052] For example, in an alternative embodiment, the clamping flange 42 can be a protruding rib or an inwardly recessed groove structure, as long as it can achieve the fixation of the brush-like structure 41. These do not deviate from the principle of the present invention, so they will all fall within the protection scope of the present invention.

[0053] For example, in another alternative embodiment, the substrate 4 can be a hemispherical structure, a frustum of a pyramid, a frustum of a cone, a pyramid-like structure, or a splicing structure of a frustum of a cone and a hemisphere, as long as it can ensure that the area of the substrate 4 gradually decreases from the cross-section close to the wave wheel 3 to the cross-section far from the wave wheel 3. These do not deviate from the principle of the present invention, so they will all fall within the protection scope of the present invention.

[0054] For example, in another alternative embodiment, the hollow barrel can be set separately, or a barrel-shaped hole can be opened on the substrate 4, or a groove-like structure can be opened on the substrate 4, as long as it can achieve that there is a connection hole at its bottom and the connection hole can be connected to the wave wheel 3. These do not deviate from the principle of the present invention, so they will all fall within the protection scope of the present invention.

[0055] For example, in another alternative embodiment, the base body 4 can be integral with the agitator 3 or detachable, as long as the shoe washing process can be achieved, and these do not deviate from the principle of the present invention, so they will all fall within the protection scope of the present invention.

[0056] For example, in another alternative embodiment, the covering layer 411 can be made of silicone or plastic. It can be fixed by connecting with the snap-over edge 42 of the base body 4 through its own elasticity, or the connection and fixation with the base body 4 can be achieved by adding an elastic structure at the edge of the covering layer 411. As long as the effective connection and fixation between the covering layer 411 and the base body 4 can be achieved, these do not deviate from the principle of the present invention, so they will all fall within the protection scope of the present invention.

[0057] Finally, it should be noted that although the present invention is described by taking the shoe washing machine as an example, it is obvious that the shoe washing machine of the present invention can also be applied to other similar washing devices. For example, the base body 4 of the present solution can also be applied to the washing of fruits, toys, hats with brims, etc., or the base body 4 can be applied to a washing machine to meet the diverse washing needs of users.

[0058] So far, the technical solution of the present invention has been described in combination with the preferred embodiments shown in the 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 all fall within the protection scope of the present invention.
