Description

Technical Field

[0001] This utility model relates to the field of shoe washing machine technology, specifically to an energy-saving shoe washing machine. Background Technology

[0002] Shoe washing machines are household appliances specifically designed for cleaning footwear. Currently, shoe washing machines on the market typically fall into two categories based on brush configuration: One type has side brushes fixed directly to the inner wall of the outer tub, while a rotating main brush is located inside. A single motor drives the main brush, utilizing the friction between the rotating side and main brushes to scrub the shoes. This type of machine is simple, has low production costs, and is energy-efficient. However, because the side brushes are fixed, they cannot rotate synchronously with the main brush, thus preventing the dehydration of the shoes. The other type uses a dual-brush cleaning structure, exemplified by the impeller type (authorization number CN214434120U). Taking a shoe washing machine as an example, an inner tub is set inside an outer tub. A pulsator is set at the bottom of the inner tub, and an outer shoe brush is set on the inside of the inner tub to clean the outside of the shoes. A supporting pedestal is set on the pulsator, and multiple brush columns are set on the top of the supporting pedestal. Dual motors drive the inner tub and the pulsator separately, so that the pulsator and the inner tub can rotate in the same direction at different speeds or in opposite directions. By different rotation directions or speeds, the brush columns and the outer shoe brush can fully rub against the shoes, ensuring the friction and cleaning effect of the brush columns and the outer shoe brush on the inside and outside of the shoes. During dehydration, the dual motors drive the inner tub and the pulsator to rotate in the same direction at the same speed to dehydrate the shoes.

[0003] However, this pulsator-type shoe washing machine also has significant drawbacks in use: First, the dual-motor architecture increases the overall production cost; second, the dual-motor model consumes more electricity than the single-motor model, and is significantly less environmentally friendly and energy-saving than the single-motor solution. This not only increases the user's operating costs, but also does not conform to the current trend of green and energy-saving development in the home appliance industry. Utility Model Content

[0004] In view of this, it is necessary to provide an energy-saving shoe washing machine that is convenient for dehydration and can reduce energy consumption, so as to solve the technical problems existing in the above-mentioned technologies.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An energy-saving shoe washing machine includes an outer tub with a drain outlet at the bottom, a drive motor, a brush tub with an open top, and a transmission mechanism. The brush tub is rotatably and vertically mounted inside the outer tub. The transmission mechanism is rotatably mounted at the bottom of the inner side of the brush tub. Side brushes for cleaning the outer surface of the shoe are vertically mounted on the inner wall of the brush tub. Inner brushes for cleaning the inner lining of the shoe are vertically mounted at the top of the transmission mechanism. Multiple inner brushes are evenly distributed in a ring around the top of the transmission mechanism. Each inner brush can extend into the shoe, allowing the shoe to be hung in the brush tub and rotate around the inner brush. The side brushes can contact the outer surface of the shoe hanging in the brush tub. The drive motor is located at the bottom of the outer tub, and its shaft passes through the brush tub and connects to the transmission mechanism. The system connects to a drive motor that drives each inner brush to rotate via a transmission mechanism, washing the inside and outside of the shoe. The shoe body rotates adaptively around the inner brushes under their scrubbing force, allowing the side brushes to wash the outer surface of the shoe. A limiting component is located at the bottom of the outer tub, and a matching limiting groove is located on the lower end of the brush tub. During washing, the limiting component rises with the water level in the outer tub and inserts into the limiting groove, preventing the brush tub from rotating. This allows the transmission mechanism to rotate relative to the brush tub, driving each inner brush to revolve within the brush tub. During dehydration, the limiting component descends with the water level in the outer tub, separating from the limiting groove and releasing the stop on the brush tub. This allows the brush tub to rotate adaptively in the same direction as the transmission mechanism under friction, thus dehydrating the shoe.

[0007] Preferably, the limiting component includes a limiting cylinder with its upper and lower ends communicating and a floating buoyancy valve. The limiting cylinder is vertically fixed at the bottom of the inner part of the outer barrel. The lower end of the limiting cylinder is connected to the drain outlet of the outer barrel. The upper end of the limiting cylinder is directly opposite the limiting groove on the lower end face of the brush barrel. The buoyancy valve is movably inserted into the limiting cylinder and can float or sink in the limiting cylinder with the water level. Multiple limiting grooves are formed around the circumference of the lower end face of the brush barrel. After the buoyancy valve floats with the water level, the upper end of the buoyancy valve can extend out of the limiting cylinder and insert into any one of the limiting grooves to restrict the rotation of the brush barrel.

[0008] Preferably, the side brushes are in multiple sets, spaced apart along the circumferential direction of the inner wall of the brush bucket.

[0009] Preferably, rollers are provided at the edge of the lower end face of the brush bucket, and the rollers are evenly distributed around the circumference of the edge of the brush bucket.

[0010] Preferably, the transmission mechanism includes an annular rotating seat, a main gear, and auxiliary gears. The annular rotating seat is rotatably mounted at the bottom of the brush bucket and is coaxially mounted with the brush bucket. The main gear is located at the center of the annular rotating seat. There are four auxiliary gears, which are evenly distributed in parallel around the upper surface of the annular rotating seat and can all rotate freely. Each auxiliary gear meshes with the main gear. There are four inner brushes, which are vertically fixed to the upper end of each auxiliary gear. The drive motor is connected to the shaft of the main gear and drives each auxiliary gear through the main gear. While the auxiliary gears drive the inner brushes to rotate, the annular rotating seat adapts to the friction of brushing the shoe body and rotates in the brush bucket to drive each inner brush to revolve.

[0011] Preferably, the lower end face of the annular rotating seat is provided with freely rotatable balls evenly distributed in a ring. When the annular rotating seat rotates, the balls can roll along with the annular rotating seat at the inner bottom of the outer barrel.

[0012] Preferably, a protective cover is also provided above the main gear and the auxiliary gear, and the lower end of the inner brush passes through the protective cover and is coaxially fixedly connected to the auxiliary gear. The protective cover encloses the main gear and the auxiliary gear. A bottom brush is provided on the upper surface of the protective cover near each inner brush, and the bottom brush can contact the heel part of the shoe body hanging in the brush bucket.

[0013] Preferably, a connecting rod is vertically arranged at the upper center of the protective cover, and a protective cover is fitted on the top of the connecting rod. The protective cover seals the upper port of the brush bucket, and a top brush is arranged in a ring on the lower end face of the protective cover. The top brush is arranged in a ring and can contact the toe part of the shoe body hanging in the brush bucket.

[0014] Preferably, the transmission mechanism further includes a planetary reducer, the input end of which is connected to the drive motor shaft, and the output end of which is connected to the main gear shaft. The drive motor drives the main gear to rotate through the planetary reducer.

[0015] Preferably, the inner bottom of the brush bucket is provided with a stop mechanism, which includes a stop block, a stop post, and a pin. The pin is vertically disposed at the inner bottom of the brush bucket and located outside the annular rotating seat. The stop block is sleeved on the pin and can rotate freely around the pin. Three stop claws are provided parallel to the outer side of the stop block and are distributed at 90° intervals around the stop block. The stop post is fixed to the inner bottom of the brush bucket and located on the side of the pin away from the annular rotating seat, adjacent to the stop post. The outer side of the annular rotating seat is provided with a protrusion corresponding to the stop claw. Each time the annular rotating seat rotates in the same direction, the protrusion can contact one of the stop claws once and actuate the stop. When the pawl rotates once in the corresponding direction, the first pawl on the stop block is turned to face the annular rotating seat by the protruding post. The opposite end pawl can be stopped by the post to restrict the stop block from continuing to rotate. In turn, the first pawl can stop the protruding post on the annular rotating seat, restricting the annular rotating seat from continuing to rotate. When the annular rotating seat rotates in the opposite direction for one revolution, the protruding post can turn the pawl once. When the last pawl on the stop block is turned to face the annular rotating seat by the protruding post, the opposite first pawl can be stopped by the post to restrict the stop block from continuing to rotate. In turn, the last pawl can stop the protruding post on the annular rotating seat, restricting its continued rotation.

[0016] As can be seen from the above technical solution, the energy-saving shoe washing machine provided in this application, by vertically arranging a freely rotatable brush bucket inside an outer bucket, setting side brushes on the inner wall of the brush bucket, rotatably arranging a transmission mechanism at the inner bottom of the brush bucket, and setting an inner brush at the upper end of the transmission mechanism, drives the inner brush to rotate within the brush bucket via a drive motor, causing the shoe body to adaptively rotate around the inner brush under the brushing force, so that the side brushes can brush the outer surface of the shoe body. Furthermore, by setting a limiting component at the bottom of the outer bucket, its beneficial effect is that during brushing, the limiting component can float upwards with the water level in the outer bucket. The stop brush bucket rotates, and the friction force causes the transmission mechanism to rotate relative to the brush bucket. This allows the inner brush to rotate on its own axis and revolve around the center within the brush bucket, ensuring the brushing force of the inner and side brushes on the shoe body. During dehydration, the limiting component can separate from the limiting groove as the water level drops, releasing the stop on the brush bucket. This allows the brush bucket to adaptively rotate in the same direction with the transmission mechanism under the action of friction, thus achieving the dehydration operation of the shoe body. This energy-saving shoe washing machine can achieve brushing and dehydration operations with just one drive motor. It has a simple structure, low production cost, and achieves the goal of energy saving and consumption reduction. Attached Figure Description

Detailed Implementation

[0032] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0033] Please refer to Figures 1 to 5 This utility model provides an energy-saving shoe washing machine, including an outer tub 10 with a drain outlet 11 at the bottom, a drive motor 20, a brush tub 30 with an open top, and a transmission mechanism 40. The brush tub 30 is rotatably and vertically arranged inside the outer tub 10. The transmission mechanism 40 is rotatably arranged at the bottom of the brush tub 30. Side brushes 31 for brushing the exterior of the shoe are vertically arranged on the inner side wall of the brush tub 30, and inner brushes 41 for brushing the interior of the shoe are vertically arranged at the top of the transmission mechanism 40. The inner brushes 41 are cylindrical brushes, and multiple inner brushes 41 are evenly distributed in a ring around the top of the transmission mechanism 40. Each inner brush 41 can extend into the shoe, allowing the shoe to be cleaned. The inner brush 41 is hung in the brush bucket 30, allowing the shoe body to rotate around the inner brush 41. The side brush 31 contacts the outer surface of the shoe body hanging in the brush bucket 30. The drive motor 20 is located at the lower end of the outer bucket 10. The shaft end of the drive motor 20 passes through the outer bucket 10 and the brush bucket 30 and is connected to the transmission mechanism 40. The drive motor 20 can drive each inner brush 41 to rotate in the brush bucket 30 through the transmission mechanism 40. Since the shoe body is in contact with the side brush 31, the inner brush 41 and the side brush 31 form a mutual frictional force on the shoe body under the friction of the side brush 31. Under the brushing force of the inner brush 41, the shoe body will adaptively rotate around the inner brush 41. During the rotation of the shoe body, the side brush 41 rotates around the inner brush 41. 1. The outer surface of the shoe body is brushed. A limiting member 50 is provided at the bottom of the outer tub 10, and a limiting groove 32 matching the limiting member 50 is provided on the lower end face of the brush tub 30. When the shoe body is brushed, after water is added to the outer tub 10, the limiting member 50 can float up with the water level in the outer tub 10 and can be inserted into the limiting groove 32 to stop the brush tub 30 from rotating. At this time, the brush tub 30 is in a fixed state. During the process of the drive motor 20 driving the inner brush 41 to rotate and brush through the transmission mechanism 40, the mutual friction force formed by the inner brush 41 and the side brush 31 on the shoe body will act on the transmission mechanism 40, which can make the transmission mechanism 40 and the brush tub 30 rotate relative to each other. In this way, the transmission mechanism 40 rotates relative to the brush tub 30. The mechanism 40 can drive each inner brush 41 to revolve in the brush bucket 30, so that the shoe body moves in a ring in the brush bucket 30 during the brushing process, and performs dynamic brushing. When the brushing is completed and dehydration is performed, the limiting member 50 can separate from the limiting groove 32 as the water level in the outer bucket 10 drops, releasing the stop on the brush bucket 30. At this time, the brush bucket 30 is in a free rotation state. The drive motor 20 continues to drive the inner brush 41 to rotate. During the brushing process, the mutual friction force formed by the inner brush 41 and the side brush 31 on the shoe body will act on the transmission mechanism 40 and the brush bucket 30 at the same time, so that the brush bucket 30 follows the transmission mechanism 40 to adaptively rotate in the same direction. The centrifugal force of rotation can dehydrate the shoe body.

[0034] Please refer to Figure 3 , Figure 4 and Figure 12Specifically, the limiting component 50 includes a limiting cylinder 51 with its upper and lower ends communicating and a floating buoyancy valve 52. The limiting cylinder 51 is vertically fixed at the bottom of the inner wall of the outer tub 10. The lower end of the limiting cylinder 51 is connected to the drain outlet 11 of the outer tub 10, and the upper end of the limiting cylinder 51 is directly opposite the limiting groove 32 on the lower end face of the brush tub 30. The buoyancy valve 52 is movably inserted into the limiting cylinder 51. The buoyancy valve 52 is a hollow columnar structure that has buoyancy in water and can float on the water surface. During washing, the drain outlet 11 is closed. When water is added to the outer tub 10, the water will enter the limiting cylinder 51, and the buoyancy valve 52 will float with the water level. The limiting groove 32... Multiple grooves are formed around the lower end face of the brush bucket 30. When the limiting groove 32 of the brush bucket 30 rotates to the position corresponding to the buoyancy valve 52, the buoyancy valve 52 floats up. The upper end of the buoyancy valve 52 can extend out of the limiting cylinder 51 and insert into any one of the limiting grooves 32, while the lower end of the buoyancy valve 52 remains in the limiting cylinder 51. The limiting cylinder 51 provides lateral support to the buoyancy valve 52, and the buoyancy valve 52 restricts the rotation of the brush bucket 30. After the brushing is finished, the drain outlet 11 is opened, and the water in the outer bucket 10 is discharged. The water in the limiting cylinder 51 is also discharged. At this time, the buoyancy valve 52 will descend into the limiting cylinder 51 with the water level, releasing the restriction on the brush bucket 30.

[0035] Please refer to Figure 2 or Figure 11 The side brushes 31 are in multiple sets and are spaced apart along the inner wall of the brush barrel 30.

[0036] Please refer to Figure 12 Furthermore, a roller 33 is provided at the edge of the lower end face of the brush bucket 30. The roller 33 is evenly distributed around the edge circumference of the brush bucket 30. The roller 33 can roll freely in the direction of rotation of the inner bottom of the outer bucket 10 towards the brush bucket 30. The roller 33 is used to provide support for the brush bucket 30, reduce the friction between the brush bucket 30 and the outer bucket 10, and keep the brush bucket 30 stable during the brushing and dehydration process.

[0037] Please refer to Figures 6 to 8The transmission mechanism 40 includes an annular rotating base 42, a main gear 43, and auxiliary gears 44. The annular rotating base 42 is rotatably disposed at the bottom of the brush barrel 30 and is coaxially disposed with the brush barrel 30. The main gear 43 is rotatably disposed at the center of the annular rotating base 42. Preferably, there are four auxiliary gears 44, which are evenly distributed in parallel around the upper end face of the annular rotating base 42 and can all rotate freely. Each auxiliary gear 44 meshes with a main gear 43. A connecting sleeve for fixing an inner brush 41 is provided at the upper shaft end of each auxiliary gear 44. There are four inner brushes 41, which are vertically fixed in the connecting sleeves of each auxiliary gear 44. The shaft end of the drive motor 20 passes through the brush barrel 30 and is connected to the shaft of the main gear 43. The drive motor 20 drives the main gear 43. The rotation is driven by the main gear 43, which in turn drives the auxiliary gears 44 to rotate. The auxiliary gears 44 then drive the inner brush 41 to rotate. While the inner brush 41 is rotating and brushing the shoe body, the friction between the inner brush 41 and the side brush 31 acts on the annular rotating seat 42 and the brush bucket 30. When the brush bucket 30 is in a fixed state, the annular rotating seat 42 will rotate relative to the brush bucket 30 under the action of this friction, which will drive the inner brush 41 to revolve in the brush bucket 30. When the brush bucket 30 is in a free-rotating state, the friction between the inner brush 41 and the side brush 31 acts on the annular rotating seat 42 and the brush bucket 30 at the same time, so that the brush bucket 30 follows the annular rotating seat 42 to rotate in the same direction. Thus, the centrifugal force can be used to dehydrate the shoe body.

[0038] Please continue reading. Figure 6 In this embodiment, the drive motor 20 is a servo motor, which can rotate in both forward and reverse directions under the control of a controller. To improve transmission efficiency, the aforementioned transmission mechanism 40 further includes a planetary reducer 46. The input end of the planetary reducer 46 is connected to the output shaft of the drive motor 20, and the output end of the planetary reducer 46 is connected to the main gear 43. The drive motor 20 drives the main gear 43 to rotate through the planetary reducer 46. The planetary reducer 46 is used to reduce the rotational speed of the drive motor 20 and increase the output torque of the drive motor 20.

[0039] Please continue reading. Figure 6 Furthermore, the lower end face of the annular rotating seat 42 is provided with freely rotatable balls 45 evenly distributed in a ring. When the annular rotating seat 42 rotates, the balls 45 can roll along with the annular rotating seat 42 at the inner bottom of the outer barrel 10. The balls 45 are used to provide support for the annular rotating seat 42, reduce the friction between the annular rotating seat 42 and the brush barrel 30, and enable the annular rotating seat 42 to maintain stable rotation in the brush barrel 30.

[0040] Please continue reading. Figure 5 and Figure 6Furthermore, a protective cover 60 is also fastened above the main gear 43 and the auxiliary gear 44. The lower end of the inner brush 41 passes through the protective cover 60 and is coaxially fixedly connected to the auxiliary gear 44. The protective cover 60 is used to shield and protect the main gear 43 and the auxiliary gear 44, prevent the main gear 43 and the auxiliary gear 44 from being exposed, and improve the safety of use.

[0041] Please continue reading. Figure 5 and Figure 9 Furthermore, a connecting rod 62 is vertically arranged at the upper center of the protective cover 60. A detachable cover 63 is fitted onto the top of the connecting rod 62. After the shoe is hung in the brush bucket 30, the cover 63 is fitted onto the connecting rod 62, sealing the upper end of the brush bucket 30 and protecting the shoe. During the brushing process, the cover 63 can block splashes of water, preventing water from spreading. In addition, to improve the cleaning efficiency of the heel and toe of the shoe, a top brush 64 is arranged in a ring on the lower end of the cover 63. The top brush 64 is arranged in a ring and faces the upper end of the inner brush 41. After the cover 63 is fitted onto the connecting rod 62, the top brush 64 can contact the toe of the shoe hanging in the brush bucket 30. During the washing process, the top brush 64 can clean the toe area of ​​the shoe body; and a bottom brush 61 is provided on the upper surface of the protective cover 60 near each inner brush 41. The bottom brush 61 can contact the heel area of ​​the shoe body hanging in the brush bucket 30. During the washing process, the bottom brush 61 can clean the heel area of ​​the shoe body.

[0042] Please continue reading. Figure 5 , Figure 11 , Figure 13 , Figure 14Furthermore, a stop mechanism 70 is provided at the inner bottom of the brush barrel 30. The stop mechanism 70 includes a stop block 71, a stop post 72, and a pin 73. The pin 73 is vertically disposed at the inner bottom of the brush barrel 30 and located outside the annular rotating seat 42. The stop block 71 is sleeved on the pin 73 and can rotate freely around the pin 73. Three stop claws 74 are provided parallel to the outer side of the stop block 71 and are distributed at 90° intervals around the stop block 71. The stop post 72 is fixed at the inner bottom of the brush barrel 30 and located on the side of the pin 73 away from the annular rotating seat 42, adjacent to the stop post 72. A protrusion 47 corresponding to the stop claw 74 is fixedly disposed on the outer side of the annular rotating seat 42. Each time the annular rotating seat 42 rotates in one direction, the protrusion 47 can contact one of the stop claws 74 once and actuate the stop. When the pawl 74 rotates once in the direction corresponding to the rotation, after the first pawl 74 on the stop block 71 is turned by the protrusion 47 to face the annular rotating seat 42, the opposite end pawl 74 can be stopped by the stop post 72 to limit the stop block 71 from continuing to rotate. In addition, the first pawl 74 can stop the protrusion 47 on the annular rotating seat 42 to limit the annular rotating seat 42 from continuing to rotate. When the annular rotating seat 42 rotates once in the opposite direction, the protrusion 47 can turn the pawl 74 to rotate in the opposite direction once. After the last pawl 74 on the stop block 71 is turned by the protrusion 47 to face the annular rotating seat 42, the opposite first pawl 74 can be stopped by the stop post 72 to limit the stop block 71 from continuing to rotate. In addition, the last pawl 74 can stop the protrusion 47 on the annular rotating seat 42 to limit its continued rotation.

[0043] Specifically, in this embodiment, the stop block 71 adopts a three-claw structure. The stop claws 74 at the head and tail ends of the stop block 71 are two opposing stop claws 74 on both sides of the stop block 71. During the actual brushing operation, the drive motor 20 is controlled by the controller to drive the inner brush 41 to rotate in both forward and reverse directions. When the inner brush 41 rotates in the forward direction, the annular rotating seat 42 rotates in the reverse direction under the action of friction. The annular rotating seat 42 rotates one revolution in the reverse direction. The protrusion 47 on the annular rotary seat 42 will cause the stop block 71 to rotate forward once. When the annular rotary seat 42 rotates counterclockwise twice, the stop pawl 74 at the tail end of the stop block 71 will be blocked by the stop post 72. When the annular rotary seat 42 rotates counterclockwise for the third time, the protrusion 47 will touch the stop pawl 74 at the head end of the stop block 71. At this time, the stop block 71 stops rotating under the stopping action of the stop post 72, and the protrusion 47 is stopped by the stop pawl 74 at the head end, preventing it from passing through, thereby restricting its movement. The annular rotating seat 42 continues to rotate in the reverse direction; when the controller controls the inner brush 41 to rotate in the reverse direction, the annular rotating seat 42, under the action of friction, rotates in the brush barrel 30 in the forward direction. For each revolution of the annular rotating seat 42 in the forward direction, the corresponding protrusion 47 on the annular rotating seat 42 will push the stop block 71 to rotate in the reverse direction once. When the annular rotating seat 42 rotates two revolutions in the forward direction, the stop claw 74 at the head of the stop block 71 will be blocked by the stop post 72. When the annular rotating seat 42 rotates to the third revolution... When the protruding post 47 touches the stop claw 74 at the tail end of the stop block 71, the stop claw 74 at the tail end of the stop block 71 will block the protruding post 47 from continuing to pass, thereby restricting the annular rotating seat 42 from continuing to rotate in the forward direction. In this way, by restricting the annular rotating seat 42 to pause its rotation once every three revolutions by the stop block 71, the inner brush 41 can temporarily stop its revolution and only perform brushing in its own rotation state, changing the brushing operation state and realizing a brushing mode that combines dynamic brushing and static brushing.

Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
