Description

Technical Field

[0001] This utility model relates to the field of small-scale shoe and clothing cleaning equipment, specifically to a shoe washing machine with an automatic drum return function. Background Technology

[0002] A shoe washing machine is a device used for washing shoes. Its internal design is different from that of a washing machine. Shoe washing machines have brushes added to the inside of the inner tub and the impeller shaft. When the machine is running, the friction between the brushes and the shoes can achieve the effect of washing shoes. However, the appearance and size of existing shoe washing machines on the market are similar to those of washing machines.

[0003] For example, Chinese patent application CN202310159838.4 discloses: "A shoe washing machine with a column brush structure, comprising: a washing tub; a shoe rack disposed within the washing tub; a turntable rotatably disposed within the washing tub; a column brush structure with its lower end mounted on the turntable; a limiting block for limiting the upper end of the column brush structure; the column brush structure is movable up and down to achieve relative rotation or relative stillness between the column brush structure and the shoe rack. The vertical movement of the column brush structure allows for relative rotation or relative stillness between the column brush structure and the shoe rack; during washing, controlling the relative rotational movement of the column brush structure and the shoe rack enables brushing of the outer side of the shoes; during spin-drying, controlling the relative stillness between the column brush structure and the shoe rack prevents relative movement between them, avoiding wear between the column brush structure and the shoes, and protecting both the column brush structure and the shoes; and the vertical movement of the column brush structure simplifies the structure."

[0004] However, including the solutions described in the aforementioned patents, one problem with existing shoe washing machines on the market is their large size, making them inconvenient to move indoors and impossible to carry outdoors. As the demand for different environments increases, portable shoe washing machines are gradually appearing on the market. Compared to the original bucket brush type shoe washing machines, they mainly rely on the internal drum to wash shoes. The shoes to be washed can be placed in the drum, and when the drum rotates under the drive device, the brushes on the inner wall of the drum can complete the washing of the shoes. This type of shoe washing machine can greatly reduce its overall size.

[0005] However, existing small drum shoe washing machines have more than one opening on the outer shell. Since shoes need to be loaded into the drum, a pick-up and drop-off window also needs to be made on the drum to facilitate the removal and placement of shoes. This leads to a problem: since the orientation of the pick-up and drop-off window on the drum is uncontrollable after each washing cycle, when users need to take out the washed shoes, they often need to manually rotate the drum to align the pick-up and drop-off window with the opening on the outer shell before taking out the shoes. This operation not only makes the overall operation of the shoe washing machine complicated, but manually rotating the drum can also easily damage the drive unit. Summary of the Invention

[0006] In order to overcome the shortcomings of existing small-sized drum shoe washing machines, which cannot automatically return the drum to its correct position and require manual operation, resulting in complicated operation and potential damage to the drive device, this utility model provides a shoe washing machine with an automatic drum return function.

[0007] The technical solution of this utility model to solve its technical problem is: a shoe washing machine with an automatic drum return function, comprising:

[0008] The outer shell has a cleaning chamber inside and an opening at the top that communicates with the cleaning chamber. A flip cover is also rotatably connected to the opening on the outer shell. The flip cover can be closed or opened relative to the opening.

[0009] A roller is disposed in the cleaning chamber and rotatably connected to the outer shell. The roller has a water passage hole. Liquid can be injected into the cleaning chamber and the liquid level can be at least above the bottom side of the roller, so that the liquid can enter the roller through the water passage hole. A pick-up and put-out window is also provided on the periphery of the roller, through which shoes enter and exit the roller.

[0010] A drive unit is connected inside the housing and is connected to the roller in a transmission connection to drive the roller to rotate relative to the cleaning chamber;

[0011] The roller has a centered state relative to the outer casing, in which the pick-up and put-down window on the roller is directly opposite the opening of the outer casing;

[0012] It also includes:

[0013] The return assembly includes a first sensor connected inside the housing and a first trigger connected to the roller. The first trigger can rotate with the roller, thereby moving away from or closer to the first sensor.

[0014] When the roller is in the aligned state relative to the outer shell, the first trigger is in the closest position relative to the first sensor, thereby triggering the first sensor.

[0015] Furthermore, it also includes a door contact assembly, which includes a second sensor connected inside the housing and a second trigger connected to the flip cover, the second trigger being able to move away from or closer to the second sensor relative to the flip cover;

[0016] Furthermore, when the flip cover is closed relative to the opening of the outer shell, the second trigger is in the closest position relative to the second sensor, thereby triggering the second sensor.

[0017] Furthermore, an electronic control board is also provided inside the outer casing. The drive device, the first sensor, and the second sensor are all electrically connected to the electronic control board. When the flip cover switches from the closed state to the open state, the electronic control board can control the drive device to start, so as to drive the roller to rotate, until the first trigger triggers the first sensor, and then the electronic control board controls the drive device to stop.

[0018] Furthermore, an element cavity is provided on one side of the cleaning chamber inside the outer casing. The driving device and the first sensing element are both disposed in the element cavity. The roller is placed horizontally in the cleaning chamber so that the right end of the roller is close to the element cavity, and the first trigger element is connected to the right end face of the roller.

[0019] In one preferred embodiment of the present invention, the rotation center of the roller is located at the center of its left and right end faces, while the trigger is located at the periphery of the right end face of the roller.

[0020] Furthermore, a mounting base is protruding on the right end face of the roller, and a fitting groove is also provided on the mounting base. The first trigger element is fixedly fitted into the fitting groove. Two limiting ribs are also protruding on the cavity wall of the element cavity. The two limiting ribs together form a mounting position, and the first sensing element is connected to the mounting position.

[0021] Furthermore, an electrical control cavity is also provided on one side of the cleaning chamber inside the outer shell. The electrical control board and the second sensing element are both disposed in the electrical control cavity. When the flip cover is in a closed state relative to the opening of the outer shell, the right side of the flip cover corresponds to the formation of the electrical control cavity, and the second trigger element is connected to the right side of the flip cover.

[0022] Furthermore, two first mounting ribs protrude from the inner wall of the right side of the flip cover, and the first mounting ribs together form a first slot, in which the second trigger is fixedly inserted; two second mounting ribs protrude from the inner wall of the electronic control cavity, and the second mounting ribs together form a second slot, in which the second sensing element is fixedly inserted.

[0023] In one preferred embodiment of the specific configuration of the return component and the door contact component in this utility model, the first sensing element and the second sensing element are both configured as Hall elements, and the first trigger element and the second trigger element are both configured as magnetic blocks.

[0024] Furthermore, a flip door is also connected to the roller at the pick-up / placement window.

[0025] The automatic return-to-center process of this utility model:

[0026] Before, during, or after washing shoes, when the flip-top is opened from the opening in the casing, the second sensor detects the movement of the second trigger and sends the information back to the control board. If the first trigger is not in the closest position relative to the first sensor at this time, the control board will start the drive unit, causing the drum to rotate until the first trigger moves to the closest position relative to the first sensor. At this point, the first sensor is triggered and sends the information back to the control board, which then stops the drive unit, causing the drum to stop rotating. Simultaneously, the pick-up and drop-off window on the drum is aligned with the opening in the casing and is in the correct position. In this state, the user can directly open the flip-top door on the drum through the opening in the casing to put shoes into or take shoes out of the drum.

[0027] The beneficial effects of this utility model are as follows:

[0028] 1. This shoe washing machine is equipped with a return-centering component. By relying on the sensing of the first trigger element by the first sensor element, the rotation of the roller inside the shoe washing machine shell can be monitored. When the first trigger element is in the trigger position relative to the first sensor element, the roller is in the return-centering state relative to the shell, thus providing a control basis for the return-centering of the roller every time the shoe washing machine is opened.

[0029] 2. Relying on the door contact structure, the opening and closing status of the flip cover on the shoe washing machine can be monitored. With the return component and the electronic control board, the roller can rotate and switch to the return state in time whenever it is in the open state. This ensures that the pick-up and drop-off window of the roller is facing the opening of the outer shell in this state, without the need for additional manual operation, thus simplifying the overall operation process of this shoe washing machine.

[0030] 3. An optimal setting scheme for the first trigger element on the roller is provided. Setting the first trigger element on the right end face of the roller not only ensures that it rotates with the roller, but also brings it closer to the first sensing element located in the element cavity. Setting the first trigger element on the periphery of the right end face of the roller can make the angular deviation of the roller during the return process smaller.

[0031] 4. The connection method between the return component and the door contact component in this shoe washing machine is simple and effective. It not only ensures the firmness of the connection, but also makes the installation of the two components very convenient during the production process of this shoe washing machine.

[0048] Example 1

[0049] Reference Figures 1 to 11 As shown, a shoe washing machine with an automatic roller return function includes a housing 1, a roller 5, a drive unit 8, and a return assembly. The housing 1 has a cleaning chamber 2 inside, with an opening 3 at its top communicating with the cleaning chamber 2. A flip cover 4 is rotatably connected to the housing 1 at the opening 3, and the flip cover 4 can be closed or opened relative to the opening 3. The roller 5 is disposed within the cleaning chamber 2 and rotatably connected to the housing 1. The roller 5 has a water passage hole 6, allowing liquid to be injected into the cleaning chamber 2 until the liquid level at least covers the bottom of the roller 5, thus enabling the liquid to enter the roller 5 through the water passage hole 6. A pick-up / drop-off window 7 is also provided on the periphery of the roller 5, through which shoes enter and exit the roller. 5; The driving device 8 is connected inside the housing 1, and the driving device 8 is connected to the roller 5 to drive the roller 5 to rotate relative to the cleaning chamber 2; The roller 5 has a return state relative to the housing 1, in which the pick-up and drop window 7 on the roller 5 is directly opposite the opening 3 of the housing 1; The return assembly includes a first sensing element 9 connected inside the housing 1 and a first trigger element 10 connected to the roller 5. The first trigger element 10 can rotate with the roller 5, thereby moving away from or closer to the first sensing element 9; When the roller 5 is in the return state relative to the housing 1, the first trigger element 10 is in the closest position relative to the first sensing element 9, thereby triggering the first sensing element 9.

[0050] Combination Figure 6 , Figure 7 , Figure 10 and Figure 11As shown, this embodiment also includes a door contact assembly, which includes a second sensor 11 connected to the housing 1 and a second trigger 12 connected to the flip cover 4. The second trigger 12 can move with the flip cover 4, thereby moving away from or closer to the second sensor 11. When the flip cover 4 is closed relative to the opening 3 of the housing 1, the second trigger 12 is in the closest position relative to the second sensor 11, thereby triggering the second sensor 11.

[0051] Combination Figure 4 and Figure 11 As shown, in this embodiment, an electronic control board 13 is also provided inside the outer shell 1. The driving device 8, the first sensing element 9, and the second sensing element 11 are all electrically connected to the electronic control board 13. When the flip cover 4 switches from the closed state to the open state, the electronic control board 13 can control the driving device 8 to start, so as to drive the roller 5 to rotate until the first trigger element 10 triggers the first sensing element 9, and then the electronic control board 13 controls the driving device 8 to stop.

[0052] Combination Figure 4 , Figure 5 , Figure 8 and Figure 9 As shown, in this embodiment, an element cavity 14 is also provided on one side of the cleaning chamber 2 inside the outer shell 1. The driving device 8 and the first sensing element 9 are both disposed in the element cavity 14. The roller 5 is placed horizontally in the cleaning chamber 2 so that the right end of the roller 5 is close to the element cavity 14, and the first trigger element 10 is connected to the right end face of the roller 5.

[0053] Combination Figure 2 and Figure 8 As shown, in this embodiment, the rotation center of the roller 5 is located at the center of its left and right end faces, while the trigger is located at the periphery of the right end face of the roller 5.

[0054] Combination Figure 4 , Figure 5 , Figure 8 and Figure 9 As shown, in this embodiment, a mounting base 15 is protruding on the right end face of the roller 5, and a fitting groove 16 is also provided on the mounting base 15. The first trigger 10 is fixedly fitted into the fitting groove 16. Two limiting ribs 17 are also protruding on the cavity wall of the element cavity 14. The two limiting ribs 17 together form a mounting position 18, and the first sensing element 9 is connected to the mounting position 18.

[0055] Combination Figure 6 , Figure 7 , Figure 10 and Figure 11As shown, in this embodiment, an electrical control cavity 19 is also provided on one side of the cleaning cavity 2 inside the outer shell 1. The electrical control board 13 and the second sensing element 11 are both disposed in the electrical control cavity 19. When the flip cover 4 is in a closed state relative to the opening 3 of the outer shell 1, the right side of the flip cover 4 corresponds to the formation of the electrical control cavity 19, and the second trigger element 12 is connected to the right side of the flip cover 4.

[0056] Combination Figure 6 , Figure 7 , Figure 10 and Figure 11 As shown, in this embodiment, two first mounting ribs 20 protrude from the inner wall of the right side of the flip cover 4, and the first mounting ribs 20 together form a first slot 21, in which the second trigger 12 is fixedly inserted; two second mounting ribs 22 protrude from the inner wall of the electronic control cavity 19, and the second mounting ribs 22 together form a second slot 23, in which the second sensing element 11 is fixedly inserted.

[0057] Combination Figures 4 to 11 As shown, in this embodiment, the first sensing element 9 and the second sensing element 11 are both configured as Hall elements, and the first trigger element 10 and the second trigger element 12 are both configured as magnetic blocks.

[0058] Combination Figures 2 to 8 As shown, in this embodiment, a flip door 24 is also connected to the roller 5 at the pick-up / placement window 7.

[0059] The automatic return process in this embodiment is as follows: Before, during, or after washing shoes, when the flip cover 4 is opened from the opening 3 of the housing, the second sensor 11 senses the movement of the second trigger 12 away and feeds the information back to the electronic control board 13. If the first trigger 10 is not in the closest position relative to the first sensor 9 at this time, the electronic control board 13 will control the drive device 8 to start, so that the roller 5 rotates under the drive device 8 until the first trigger 10 moves to the closest position relative to the first sensor 9. At this time, the first sensor 9 is triggered and feeds the information back to the electronic control board 13. The electronic control board 13 then controls the drive device 8 to stop, so that the roller 5 stops rotating. At the same time, the pick-up and drop-off window 7 on the roller 5 is facing the opening 3 on the housing 1 and is in the return state. In this state, the user can directly open the flip door 24 on the roller 5 through the opening 3 of the housing 1 to put shoes into the roller 5 or take shoes out of the roller 5.

[0060] The advantage of this embodiment is that, by relying on the setting of the return component and the door contact component, the status of the flip cover and the roller on this shoe washing machine can be monitored in real time. When the flip cover is opened, the roller can be controlled to rotate automatically to return to the center, thereby ensuring that the pick-up and put-down window on the roller is aligned with the opening on the outer shell every time the flip cover is opened, so as to facilitate the user to pick up and put down shoes and reduce the steps of manual operation by the user.

[0061] Example 2

[0062] Reference Figure 12 and Figure 13 As shown, the main difference between this embodiment and the first embodiment described above is that:

[0063] In this embodiment, the first trigger 10 is disposed on the right end face of the roller 5 near the center, and the corresponding first sensing element 9 is also located near the center of the element cavity 14.

[0064] The orientation of the return component in this embodiment differs from that in Embodiment 1, resulting in a difference in the actual return effect of the roller 5. Since the first trigger 10 is closer to the center of the right end face of the roller 5, the deviation that occurs after the roller 5 returns to center is greater than the deviation of the roller 5 in Embodiment 1, but it can still achieve basic return to center. Therefore, this is hereby explained.

[0065] Similarly, in addition to setting the first trigger 10 on the circumference of the right end face of the roller 5 in Embodiment 1, and setting the first trigger 10 near the center of the right end face of the roller in this embodiment, the first trigger 10 can also be set in other places on the right end face of the roller 5. Only the setting position of the first sensing element 9 needs to be adjusted adaptively.

[0066] The remaining structures, methods, and advantages of this embodiment are consistent with those of Embodiment 1 above, and will not be repeated here.

[0067] Example 3

[0068] The difference between this embodiment and Embodiment 1 described above is as follows:

[0069] In this embodiment, the first sensing element 9 and the second sensing element 11 are configured as laser sensors, and the first trigger element 10 and the second trigger element 12 are configured as reflectors; the orientation of the return assembly and the door contact assembly is consistent with that of the first embodiment described above.

[0070] The working principle of the return component and trigger component in this embodiment differs from that in Embodiment 1. Embodiment 1 relies on magnetic induction for detection, while this embodiment relies on optical induction. The remaining structures, methods, and advantages of this embodiment are consistent with those in Embodiment 1 and will not be repeated here.

[0071] The above specific embodiments are merely explanations of the present utility model and are not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to the embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.
