Description

Technical Field

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

[0002] As shoe washing machines become increasingly sophisticated and the demand for reducing household chores and freeing up hands grows, they are gradually becoming a common household item. Simultaneously, the growing user base is placing higher demands on the washing experience. Common shoe washing machines feature a "waterfall-shaped" water inlet similar to that of washing machines. However, because shoes float on water and don't easily absorb water, shoe washing machines cannot thoroughly wet a large area of ​​the shoes during the water intake process, reducing cleaning efficiency.

[0003] Secondly, the presence of the bottom brush during the washing process generates a large amount of foam. While foam helps improve the cleanliness of the shoes, foam residue can remain on the inner surface and bottom edges after washing, affecting the cleanliness of rinsing and the user experience. This issue is particularly frequent when users add excessive amounts of detergent, not according to the recommended dosage.

[0004] Existing solutions to the above two problems involve pre-soaking or pre-washing the shoes before placing them in the shoe washing machine; or waiting for the foam to dissipate automatically after opening the lid, or manually wiping or washing away the foam with clean water or a cloth. However, these existing solutions require manual handling by the user, increasing their workload and reducing their satisfaction with the user experience.

[0034] Referring to Figures 1-10 It is an embodiment of a top-spraying shoe washing machine proposed in the present application, which comprises a washing cavity (not shown in the figure) and an upper cover 10, the washing cavity has an upper opening, and the upper cover 10 is arranged at the opening end of the washing cavity and can be opened and closed; an upper fixed cover 20 is arranged at the upper side of the washing cavity, and the upper cover 10 is hingedly arranged on the upper fixed cover 20. The upper cover 10 has a water inlet cavity 11, and a plurality of water spray nozzles 12 are arranged on the bottom surface of the water inlet cavity 11; a water spray opening 121 is arranged on the side of the water spray nozzle 12 away from the center of the water inlet cavity 11, and the included angle between the outer edge of the plurality of water spray openings 121 and the bottom surface of the water inlet cavity 11 gradually decreases in the direction away from the center of the water inlet cavity 11.

[0035] In the embodiment, by setting the angle between the outer edge of the plurality of water outlets 121 and the bottom surface of the water inlet cavity 11 gradually decreases in the direction away from the center of the water inlet cavity 11, the full range of spraying in the washing cavity can be achieved, the foam is eliminated, and the cleaning efficiency is increased. The water outlet on the water nozzle 12 away from the center of the water inlet cavity 11 sprays the water flow outward, which is beneficial to wash the foam reaching the upper cover 10 or the bottom edge of the washing cavity, and avoids the residue of the foam. The water outlet 121 on the water nozzle 12 close to the center of the water inlet cavity 11 sprays the water flow obliquely downward, which forms the full range of spraying in the washing cavity, is beneficial to realize the multi-angle washing of the shoes, and is beneficial to improve the cleaning efficiency. The water outlet 121 is provided on the side of the water nozzle 12 away from the center of the water inlet cavity 11, so that the water outlet 121 sprays the water flow downward and outward, avoids the intersection of the water flows sprayed by the plurality of water outlets 121, and is beneficial to the flushing and cleaning of the shoes. As shown in Figure 4 the angle between the outer edge of the water outlet 121 and the bottom surface of the water inlet cavity 11 is α, and the plurality of angles α gradually decreases in the radial outward direction of the water inlet cavity 11, that is, the height of the sprayed water flow gradually increases, which is beneficial to form the water flow in the outward direction and is beneficial to eliminate the foam reaching the upper cover 10 or the upper fixed cover 20.

[0036] In some embodiments of the present application, the water nozzle 12 has a downward spray groove 122, the water outlet 121 is provided on the groove wall of the spray groove 122, the spray groove 122 has an upper opening, and the water outlet 121 is provided on the groove wall of the spray groove 122 away from the center of the water inlet cavity 11. One water outlet 121 is preferably provided on one spray groove 122, and the center limit of the water outlet 121 is located in the radial plane of the water inlet cavity 11. The spray groove 122 is a hemispherical shell, which is beneficial to the water flow gathering in the spray groove 122 and forming pressure on the water outlet 12, and is beneficial to increasing the spraying force of the water flow. The water outlet 121 has an outer spray edge 1211 located at the outer edge and an inner spray edge 1212 opposite to the outer spray edge 1211. The outer edge of the water outlet 121 is the outer spray edge 1211, the outer spray edge 1211 is a plane structure, and the inner spray edge 1212 is a downward vertical plane structure. The outer spray edge 1211 and the inner spray edge 1212 are away from each other in the direction away from the center of the spray groove 122, which is beneficial to form the spraying and diffusing water flow.

[0037] In some embodiments of the present application, the angle between the outer spray edge 1211 and the inner spray edge 1212 of the plurality of water spray openings 121 gradually decreases in the direction away from the center of the water inlet cavity 11. The angle between the outer spray edge 1211 and the inner spray edge 1212 is the opening width of the water spray opening 121. The greater the angle between the outer spray edge 1211 and the inner spray edge 1212, the greater the width of the water flow after the water spray opening 121 sprays. Under the same water pressure, the smaller the opening, the greater the spraying force. The width of the plurality of water spray openings 121 gradually decreases in the outward direction, which is beneficial to make the water spray openings 121 away from the center of the water inlet cavity 11 spray outward and downward with great force.

[0038] In some embodiments of the present application, the water inlet cavity 11 is divided into a plurality of water inlet areas by the partition plate 13, which is beneficial to control the water inlet area of water supply and in turn control whether the water spray nozzle sprays. The first water inlet area 111 farthest from the center of the water inlet cavity 11 is provided with a first water spray nozzle that sprays water flow in the outward direction. The water inlet cavity 11 is divided into a plurality of annularly sleeved water inlet areas, so that the water spray nozzles 12 located in the same water inlet area are close to the center of the water inlet cavity 11. The water supply to one or more water inlet areas can be controlled to control the horizontal spraying range of the spray. For example, during the washing process, the first water spray nozzle can not spray water flow, which is not always horizontal. When draining at the end of the washing process, water needs to be supplied to the first water inlet area 111 for rinsing the edge of the upper cover 10, the inner side of the upper fixed cover 20, and the side of the washing cavity, etc.
