Description

Technical Field

[0001] This invention belongs to the field of washing equipment technology, specifically relating to a shoe washing machine. Background Technology

[0002] A shoe washing machine is a washing device specifically designed to clean shoes. The washing chamber of a shoe washing machine typically contains brushes, spray devices, or a combination of brushes and spray devices to clean shoes through friction and / or water jets. To meet the needs of large-capacity shoe washing, most existing shoe washing machines are designed with a pulsator structure. Specifically, a pulsator-type shoe washing machine has a washing tub that can hold multiple pairs of shoes and a rotating pulsator at the bottom of the tub. The pulsator is equipped with shoe-washing brushes, which rotate as the pulsator rotates to agitate and rub the shoes inside the tub, thus achieving the purpose of washing.

[0003] Currently, most shoe washing brushes are set up independently of the impeller. After installation, there will be an installation gap at the connection between the shoe washing brush and the impeller. This installation gap not only causes collision noise between the shoe washing brush and the impeller when the shoes rub against each other, but also gets the shoelaces stuck when the shoes are turned over. This means that users can only avoid the problem of the shoelaces getting stuck by removing the shoelaces from the shoes before putting them in. This increases the preparation work when washing shoes, and the shoelaces also need to be washed separately, which is not very convenient for washing shoes.

[0004] Accordingly, there is a need in the field for a new shoe washing machine to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems in the prior art, specifically the issues arising from installation gaps between the shoe brush and the impeller in existing shoe washing machines, which cause collision noise and easily jam shoelaces during washing, this invention provides a shoe washing machine. The shoe washing machine includes a washing tub and an impeller rotatably disposed at the bottom of the washing tub. The impeller includes a wheel body, a rotating structure disposed on the wheel body, and multiple water-repelling ribs. The rotating structure is located at the top center of the wheel body, and its radial dimension gradually decreases from bottom to top. The rotating structure is provided with first bristles, and the multiple water-repelling ribs are arranged around the rotating structure, with second bristles disposed on the water-repelling ribs.

[0006] In the preferred embodiment of the above-mentioned shoe washing machine, the rotating structure is a hemispherical structure, and the first brush bristles are distributed on the hemispherical surface of the hemispherical structure.

[0007] In the preferred embodiment of the above-mentioned shoe washing machine, a plurality of first mounting holes are provided on the hemispherical surface of the hemispherical structure, and the bottom of the first brush bristles is fixed in the first mounting holes.

[0008] In the preferred embodiment of the above-mentioned shoe washing machine, the first brush bristles are rubber bristles, and the first brush bristles are integrally formed with the hemispherical surface of the hemispherical structure.

[0009] In the preferred embodiment of the above-mentioned shoe washing machine, the water-repellent rib is a raised structure arranged radially along the impeller, and the second bristles are arranged on the top and / or side of the raised structure.

[0010] In the preferred embodiment of the above-mentioned shoe washing machine, a second mounting hole is provided on the top and / or side of the raised structure, and the bottom of the second bristles is fixed in the second mounting hole.

[0011] In the preferred embodiment of the above-mentioned shoe washing machine, the second brush bristles are rubber bristles, and the second brush bristles are integrally formed with the top and / or side of the raised structure.

[0012] In the preferred embodiment of the above-mentioned shoe washing machine, the non-protruding part of the top surface of the wheel body is provided with a third brush.

[0013] In the preferred embodiment of the above-mentioned shoe washing machine, the non-protruding part of the top surface of the wheel body is provided with a plurality of bristle setting parts along the inner edge of the circumference. Each bristle setting part includes a plurality of third mounting holes arranged in a circumferential manner, and the root of the third bristle is fixed in the third mounting hole.

[0014] In the preferred embodiment of the above-mentioned shoe washing machine, the third bristles are rubber bristles integrally formed with the non-protruding part of the top surface of the wheel body, and the third bristles are arranged along the circumferential inner edge of the non-protruding part of the top surface of the wheel body.

[0015] Those skilled in the art will understand that the impeller of the shoe washing machine of the present invention has a rotating structure at the top center of the wheel body, and multiple water-repelling ribs are arranged around the rotating structure. Brush bristles are also arranged on the rotating structure and the water-repelling ribs. Through this arrangement, on the one hand, the impeller can simultaneously perform water-repelling and agitating functions and brushing, eliminating the need for an additional shoe brush and reducing gaps in the exposed parts of the impeller in the washing space, thereby preventing shoelaces from getting stuck on the impeller or causing significant collision noise during washing. On the other hand, the rotating structure at the center of the wheel body, with its radial dimension gradually decreasing from bottom to top, and the first brush bristles, can create a large brushing surface with gentle side curves. Compared with the brushing surface of conventional cylindrical or plate-shaped shoe brushes, the brushing surface of the rotating structure of the present invention has a greater spatial expansion, increasing the brushing angle of the first brush bristles and thus providing circumferential, thorough, and comprehensive cleaning of the shoes. In addition, the second bristles on the water-repellent ribs not only rub against the shoes during the agitation of the shoes and washing water by the impeller, assisting the first bristles in cleaning the shoes, but also enhance the agitation of the washing water and shoes by the water-repellent ribs, thereby increasing the friction between the shoes and the first bristles, the second bristles and the washing water, and deeply optimizing the cleaning effect of the shoes.

[0016] Preferably, the aforementioned rotating structure is a hemispherical structure. The brushing surface formed by arranging the first bristles on the hemispherical surface of the hemispherical structure gradually increases in radial dimension from top to bottom, with a smooth and gradually expanding streamline. This allows the brushing surface to provide a certain buffering effect on the shoes as they slide down the brushing surface during the process of being agitated and thrown up by the impeller, coming into contact with the first bristles, and falling. This prolongs the friction time when the shoes come into contact with the first bristles each time, improves the shoe brushing efficiency, and provides a gentle yet efficient shoe brushing effect when washing shoes.

[0017] Preferably, the non-protruding part of the top surface of the wheel is provided with a third bristle, so that the relatively concave part of the top of the wheel also has a brushing function. This allows the shoes that fall to the non-protruding part of the top of the impeller to be rubbed and washed during the agitation of the shoes. This ensures that the shoes can rub against the bristles at each position throughout the agitation process, further optimizing the brushing efficiency and comprehensive cleaning effect of the shoes.

[0022] Those skilled in the art should understand that, in the description of this invention, terms such as "center," "upper," "lower," "vertical," "inner," and "outer," indicating directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are 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 the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0024] First refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the top structure of the impeller of the shoe washing machine of the present invention. Figure 2 This is a schematic diagram of the side structure of the impeller of the shoe washing machine of the present invention. Figure 1 and Figure 2As shown, the shoe washing machine of the present invention includes a housing (not shown in the figure), a washing tub (not shown in the figure), an impeller, and a drive device (not shown in the figure) disposed within the housing. The washing tub is vertically disposed within the housing with its opening facing upwards, and the tub body is closed to hold washing water and shoes. The impeller is disposed at the bottom of the washing tub, and the drive device is disposed below the bottom of the washing tub and passes through the washing tub to connect with the impeller, so as to drive the impeller to rotate and thus stir the washing water and shoes in the tub (the structure of the drive device is the same as the conventional drive structure of an impeller shoe washing machine, as long as it can drive the impeller to rotate, such as a direct drive motor connected to the impeller; the structure of the drive device will not be described in detail here). Specifically, the impeller includes a wheel body 1 and a rotating structure 2 and multiple water-dispersing ribs 3 disposed on the wheel body 1. The wheel body 1 is a circular wheel-shaped structure with a radial dimension smaller than the internal radial dimension of the washing tub, and it is rotatably connected to the bottom of the washing tub and connected to the drive device. The rotating structure 2 is located at the center of the top of the wheel body 1 (i.e., the side of the wheel body 1 away from the bottom of the washing tub), and the radial dimension of the rotating structure 2 gradually decreases from the bottom (i.e., the end near the wheel body 1) to the top (i.e., the end away from the wheel body 1). Multiple water-repelling ribs 3 protrude from the outer periphery of the top of the wheel body 1 and surround the rotating structure 2. The part of the top of the wheel body 1 without water-repelling ribs 3 and the rotating structure 2 is the non-protruding part 4, which has a relatively flat top surface and is recessed relative to the raised water-repelling ribs 3 and the rotating structure 2. The rotating structure 2 is provided with first bristles 5, and the water-repelling ribs 3 are provided with second bristles 6. When the driving device drives the wheel body 1 to rotate, it can drive the rotating structure 2 and the water-repelling ribs 3 to rotate synchronously, so that the surface of the shoes can be cleaned by friction from the first bristles 5 on the rotating structure 2 and the second bristles 6 on the water-repelling ribs 3.

[0025] In the above embodiments, the rotating structure 2 can be any rotating structure that rises upward from the top surface of the wheel body 1 and whose radial dimension gradually decreases from the bottom to the top, such as a dome-shaped structure, a frustum-shaped structure, a hemispherical structure, a conical structure, a truncated cone-shaped structure, etc. The rotating structure 2 being located at the top center of the wheel body 1 specifically means that the rotating structure 2 is located in the central region of the top of the wheel body 1. This central region is defined by those skilled in the art as a central region divided by a radius of a predetermined distance from the wheel body 1's axis. The rotating structure 2 is located within this central region so that it can rotate coaxially with the wheel body 1 (the rotation center of the rotating structure 2 coincides with the axis of the wheel body 1) or rotate slightly eccentrically (the rotation center of the rotating structure 2 has a small distance relative to the axis of the wheel body 1). Multiple water-repelling ribs 3 are distributed around the rotating structure 2 and located in the remaining annular region surrounding the central region of the top surface of the wheel body. The portion of the remaining annular region of the top surface of the wheel body 1 without water-repelling ribs 3 is the aforementioned non-protruding portion 4.

[0026] The above configuration allows the impeller to simultaneously perform agitation and scrubbing. When the shoes are scattered at the bottom of the washing tub, the shoes and the washing water soaking them are agitated by the rotating structure 2 and the water-repelling ribs 3. This allows the shoes to rub against the washing water on one hand, and against the first brush bristles 5 and the second brush bristles 6 on the other. This ensures that the shoes receive dual cleaning and friction from the washing water and the brush bristles during the tumbling process, achieving all-around washing of the shoes.

[0027] In a preferred embodiment, the rotating structure 2 is a hemispherical structure as shown in the figure, and the first bristles 5 are distributed on the hemispherical surface of the hemispherical structure to form a hemispherical brushing surface. As one possible example, the first bristles 5 are embedded in the hemispherical surface of the hemispherical structure. Specifically, the number of first bristles 5 is multiple clusters, and multiple first mounting holes 21 are distributed on the hemispherical surface of the hemispherical structure. The bottom of each cluster of first bristles 5 is fixed in a first mounting hole 21 by means of adhesive bonding, snap-fitting, etc. As another possible example, the first bristles 5 are rubber bristles, and the number of rubber bristles is multiple. At least the hemispherical surface layer of the hemispherical structure is made of rubber material so that the first bristles 5 are integrally formed with the hemispherical structure.

[0028] By setting the rotating structure 2 as a hemispherical structure, the hemispherical structure covered with the first bristles 5 can have a brushing surface that is approximately hemispherical in shape. The brushing surface has a smooth and gentle curve, which can not only cushion the shoes that impact the rotating structure 2, thereby reducing the obvious friction damage to the shoe surface caused by the first bristles 5 under the impact of the shoes, but also brush the shoe surface in all directions and for a longer contact time through the first bristles 5 arranged in a spatial orientation, thus achieving a reliable brushing effect that does not damage the shoes.

[0029] In another preferred embodiment, the water-repellent rib 3 is a raised structure arranged radially along the impeller as shown in the figure, and the second bristles 6 are disposed on the top (i.e., the confluence of the raised surfaces) and / or the side (i.e., on the raised surface) of the raised structure. As one possible example, the raised structure has three rows of second mounting holes 31 arranged radially, wherein the second mounting holes 31 in the middle row are arranged along the top of the raised structure, and the other two rows of second mounting holes 31 are respectively disposed on one of the raised surfaces of the raised structure near the top. The number of second bristles 6 is multiple clusters, and the bottom of each cluster of second bristles 6 is fixed in a second mounting hole 31 by means of adhesive bonding, snap-fitting, etc. As another possible example, the second bristles 6 are rubber bristles, and the number of rubber bristles is multiple. At least the raised surface and the top end face of the raised structure are made of rubber material so that the second bristles 6 are integrally formed with the raised structure. The specific shape of the water-repelling rib 3 is not limited to a straight ridge along the radial direction of the wheel body 1. For example, the water-repelling rib 3 can also be an S-shaped ridge structure arranged radially. Those skilled in the art can improve the shape of the water-repelling rib 3 according to the water-repelling requirements.

[0030] By setting a second bristle 6 on the raised structure, the shoe surface can be scrubbed by the second bristle 6 when the wheel 1 rotates. At the same time, the second bristle 6, which are arranged in rows along the radial direction of the wheel 1, can also help the raised structure to stir the washing water and the shoes, thereby improving the tumbling effect of the washing water and the shoes. This significantly improves the friction effect of the washing water on the shoes and the friction effect of the first bristle 5 or the second bristle 6 on the shoes that are tumbling more noticeably, further optimizing the cleaning efficiency and cleanliness of the shoes.

[0031] In a more preferred embodiment, in addition to the first bristles 5 and the second bristles 6, the non-protruding portion 4 on the top surface of the wheel 1 is provided with a third bristle (not shown in the figure) so that the non-protruding portion 4 of the wheel 1 also has a brushing ability. During the process of the shoe being flipped and turned by the impeller, the shoe is highly likely to roll off to the non-protruding portion 4 after rubbing against the first bristles 5 on the rotating structure 2 or the second bristles 6 on the raised structure. In this case, the rolled-off shoe can rub against the third bristles to prolong the brushing time of the shoe and further improve the washing efficiency of the shoe. As a possible example, the third bristle is provided along the circumferential inner edge of the non-protruding portion 4 (i.e., the position of the top of the wheel 1 near the circumferential edge), and a plurality of bristle setting parts are provided along the circumferential inner edge. Each bristle setting part includes a plurality of third mounting holes 41 arranged in a circumferential manner. The root of the third bristle is fixed in the third mounting hole 41 by means of snapping, bonding or other methods. As another possible example, the third bristles are rubber bristles, and the non-protruding portion 4 is made of rubber material covering at least the portion of the circumferential inner edge, so that the third bristles and the non-protruding portion 4 are integrally formed.

[0032] Regarding the above embodiments, it should be noted that the distribution of the first bristles 5, the second bristles 6, and the third bristles is not limited to the examples described above. Those skilled in the art can set the distribution of the bristles (such as distribution area, bristle orientation, etc.) according to the specific shape or size of the rotating structure 2, the specific shape or size of the raised structure, etc. For example, the first bristles 5 can also be arranged vertically spirally on the rotating structure 2, or the second bristles 6 can also include multiple rows of bristles inclined relative to the radial direction, or the third bristles can be evenly distributed on the non-protruding area. The changes in the distribution of the bristles in the above embodiments do not exceed the protection scope of the present invention.

[0033] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles 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 such changes or substitutions will all fall within the scope of protection of the present invention.
