Description
Technical Field
[0001] This utility model relates to the technical field of tableware cleaning equipment, specifically a tableware cleaning brushing mechanism and a tableware cleaning machine. Background Technology
[0002] In the daily operations of large catering establishments such as restaurants and hotels, tableware that requires continuous heating, such as mini hot pots, shabu-shabu pots, and insulated soup pots, is used extremely frequently. Because these tableware are constantly under high-temperature simmering conditions, food residue and grease tend to adhere firmly to the bottom of the pot. After prolonged exposure to high temperatures, stubborn sticky and burnt stains form, making them extremely difficult to clean.
[0003] For large catering establishments, the cleaning of such tableware is particularly problematic. On the one hand, the large volume of tableware used means that manual cleaning requires a significant investment of manpower for repeated scraping and soaking, which is not only time-consuming and labor-intensive but also consumes a large amount of employees' effective working time, impacting overall operational efficiency. On the other hand, traditional dishwashers lack targeted cleaning methods, often employing an all-around spray design that struggles to focus on stubborn stains on the bottom of the tableware. The spray pressure and cleaning angle cannot precisely target sticky or burnt areas, often resulting in residual stains on the bottom of the pot after cleaning, failing to meet cleanliness standards and even affecting subsequent use and food safety.
[0004] The aforementioned cleaning challenges not only increase the labor costs and operational burden of catering establishments, but may also leave hygiene hazards due to incomplete cleaning, becoming a common pain point for large catering establishments. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a brushing mechanism and a tableware cleaning machine for cleaning tableware.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A dishwashing brushing mechanism includes a motor, an inner brush head, a gearbox, and a rotating pot rack. The output shaft of the motor is connected to a rotating shaft. The rotating pot rack is rotatably connected to the upper part of the gearbox. The rotating shaft moves through the gearbox and the rotating pot rack and is fixedly connected to the inner brush head. The inner brush head is located on the upper part of the rotating pot rack. A transmission component is provided inside the gearbox. The motor can drive the rotating pot rack to rotate in the opposite direction relative to the inner brush head through the transmission component.
[0007] In the above structure, the tableware to be washed is placed upside down on the rotating pot rack. The rotating pot rack causes the tableware to rotate, and at the same time, the inner brush head rotates in the opposite direction. The inner brush head rubs against the inner wall of the tableware, thereby more effectively removing food residue and stains from the inside of the tableware.
[0008] The transmission assembly includes a driving bevel gear, an intermediate bevel gear, and a pot frame rotating bevel gear. All three are rotatably connected to a gearbox. The driving bevel gear is fixedly connected to the outside of the rotating shaft. The pot frame rotating bevel gear is rotatably mounted outside the rotating shaft. The intermediate bevel gear meshes with both the driving bevel gear and the pot frame rotating bevel gear. The pot frame rotating bevel gear is fixedly connected to the rotating pot frame. This structure enables the inner brush head and the rotating pot frame to rotate in opposite directions.
[0009] To achieve better cleaning results, the inner brush head and the rotating pot rack can rotate at high speed. During rotation, in order to ensure that the tableware to be cleaned moves with the rotating pot rack, a positioning mechanism is provided on the upper part of the rotating pot rack. The positioning mechanism is used to limit the tableware to follow the rotation of the rotating pot rack.
[0010] Specifically, the positioning mechanism includes several positioning posts, which are evenly distributed on the upper part of the rotating pot rack. The handles of the small hot pot, shabu-shabu pot, insulated soup pot, and other tableware to be cleaned can be put on the positioning posts or locked between two positioning posts. When the rotating pot rack rotates, the positioning posts will drive the tableware to be cleaned to rotate synchronously.
[0011] A dishwashing machine includes a top cover and a body. The top cover is slidably connected to the body. Several external brush heads are fixedly connected inside the top cover. A water tank is provided inside the body. Several nozzles and several sets of brushing mechanisms are installed on the bottom plate of the water tank. The brushing mechanism includes a motor, an inner brush head, a gearbox, and a rotating pot rack. The output shaft of the motor is connected to a rotating shaft. The rotating pot rack is rotatably connected to the upper part of the gearbox. The rotating shaft moves through the gearbox and the rotating pot rack and is fixedly connected to the inner brush head. The inner brush head is located on the upper part of the rotating pot rack. A transmission component is provided inside the gearbox. The motor can drive the rotating pot rack to rotate in the opposite direction relative to the inner brush head through the transmission component. The motor and gearbox are located on the lower part of the bottom plate of the water tank, and the inner brush head and the rotating pot rack are located on the upper part of the bottom plate of the water tank.
[0012] In the above structure, the tableware to be washed is placed upside down on the rotating pot rack, which causes the tableware to rotate. At the same time, the inner brush head rotates in the opposite direction, and the inner brush head rubs against the inner wall of the tableware to be washed, thereby more effectively removing food residue and stains from the inside of the tableware. The outer brush head scrubs the outside of the tableware.
[0013] The transmission assembly includes a drive bevel gear, an intermediate bevel gear, and a pot frame rotating bevel gear. The drive bevel gear, intermediate bevel gear, and pot frame rotating bevel gear are all rotatably connected to the gearbox. The drive bevel gear is fixedly connected to the outside of the rotating shaft. The pot frame rotating bevel gear is rotatably disposed outside the rotating shaft. The intermediate bevel gear meshes with the drive bevel gear and the pot frame rotating bevel gear respectively. The pot frame rotating bevel gear is fixedly connected to the rotating pot frame.
[0014] The bottom plate of the water tank has several mounting holes, through which the rotating bevel gear of the pot frame passes. An end cap is rotatably mounted on the outside of the rotating bevel gear of the pot frame, and the end cap is located on the upper part of the bottom plate of the water tank. Bolt holes are provided on both the bottom plate of the water tank and the end cap. A threaded hole is provided on the top of the gearbox. Bolts pass through the bolt holes of the end cap and the bottom plate of the water tank respectively and are threaded into the threaded hole of the gearbox. A skeleton oil seal is provided between the end cap and the rotating bevel gear of the pot frame to prevent water in the water tank from entering the gearbox.
[0015] The upper part of the rotating pot frame is provided with a positioning mechanism, which includes a number of positioning posts that are evenly distributed on the upper part of the rotating pot frame.
[0016] The nozzles include a main wash nozzle and a rinsing nozzle. The machine body is equipped with a main wash water pump and a rinsing water pump. The main wash nozzle is connected to the main wash water pump, and the rinsing nozzle is connected to the rinsing water pump. The bottom plate of the water tank has a drain hole, which is connected to a circulating water tank, and the circulating water tank is connected to the main washing water pump.
[0017] The top cover is equipped with a handle on the outside, which allows the top cover to move up and down by pulling the handle. A fixing tube is installed inside the top cover, and a fixing plate is connected to the lower part of the fixing tube. The fixing plate is connected to the outer brush head.
[0018] The beneficial effects achieved by this utility model are: The brushing mechanism and tableware washing machine of this utility model greatly improve the cleaning cleanliness: through the transmission component, the inner brush head and the rotating pot rack rotate in opposite directions, and the inner wall of the tableware to be cleaned forms relative friction with the inner brush head, which accurately removes stubborn sticky stains, solves the problem of incomplete cleaning in traditional methods, and ensures the cleanliness standard. This utility model of tableware washing machine improves operational efficiency and reduces costs. It adopts mechanized automatic brushing to replace manual repeated scraping, reducing labor input and time consumption. Furthermore, it integrates several brushing mechanisms to adapt to batch cleaning needs, improve tableware turnover efficiency, and reduce labor and operating costs. Attached Figure Description

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0022] Example: like Figures 1-7 As shown, a dishwashing machine includes a top cover 1 and a body 2. The top cover 1 is slidably connected to the body 2, and the whole has a flip-top structure.
[0023] The top cover 1 is internally fixedly connected to four external brush heads 4.
[0024] The machine body 2 is equipped with a water tank 6, which is located at the bottom of the top cover 1. Four sets of nozzles and four sets of brushing mechanisms are installed on the bottom plate 15 of the water tank 6.
[0025] The scrubbing mechanism includes a motor 8, an inner brush head 13, a gearbox 7, and a rotating pot frame 10. The output shaft of the motor 8 is connected to a rotating shaft 25 via a coupling. The rotating pot frame 10 is rotatably connected to the upper part of the gearbox 7. The rotating shaft 25 passes through the gearbox 7 and the rotating pot frame 10 and is fixedly connected to the inner brush head 13. The inner brush head 13 is located on the upper part of the rotating pot frame 10. A transmission component is provided inside the gearbox 7. The motor 8 can drive the rotating pot frame 10 to rotate in the opposite direction relative to the inner brush head 13 through the transmission component.
[0026] The transmission assembly includes a driving bevel gear 26, an intermediate bevel gear 24, and a pot frame rotating bevel gear 23. All three are rotatably connected to the gearbox 7. Two intermediate bevel gears 24 are symmetrically arranged, and their central axes are perpendicular to the central axis of the driving bevel gear 26. The driving bevel gear 26 is fixedly connected to the outside of the rotating shaft 25. The pot frame rotating bevel gear 23 is rotatably disposed outside the rotating shaft 25. The intermediate bevel gear 24 meshes with both the driving bevel gear 26 and the pot frame rotating bevel gear 23. The pot frame rotating bevel gear 23 is fixedly connected to the rotating pot frame 10. Bearings are provided between the driving bevel gear 26 and the gearbox 7, between the rotating shaft 25 and the pot frame rotating bevel gear 23, between the pot frame rotating bevel gear 23 and the gearbox 7, and between the intermediate bevel gear 24 and the gearbox 7.
[0027] The upper part of the rotating pot rack 10 is equipped with a positioning mechanism, which includes several positioning posts 21 evenly distributed on the upper part of the rotating pot rack 10. The handles of the small hot pots, shabu-shabu pots, insulated soup pots, etc., to be washed can be fitted onto the positioning posts 21. When the rotating pot rack 10 rotates, the positioning posts 21 will drive the tableware 5 to rotate synchronously. Alternatively, the pot handle or handle can also be engaged between two positioning posts 21, similarly achieving synchronous rotation of the tableware 5 by the positioning posts 21. This positioning mechanism is suitable for tableware with handles or handles.
[0028] The motor 8 and gearbox 7 are located at the lower part of the bottom plate 15 of the water tank 6, while the inner brush head 13 and the rotating pot rack 10 are located at the upper part of the bottom plate 15 of the water tank 6. Specifically, the bottom plate 15 of the water tank 6 has four mounting holes 16, through which the rotating bevel gear 23 of the pot rack passes. An end cap 14 is rotatably mounted on the outside of the rotating bevel gear 23 of the pot rack, located at the upper part of the bottom plate 15 of the water tank 6. Bolt holes are provided on both the bottom plate 15 and the end cap 14. A threaded hole is provided on the top of the gearbox 7. Bolts pass through the bolt holes of the end cap 14 and the bottom plate 15 respectively and are threaded into the threaded hole of the gearbox 7. A skeleton oil seal 22 is provided between the end cap 14 and the rotating bevel gear 23 of the pot rack to prevent water in the water tank 6 from entering the gearbox 7.
[0029] Each set of nozzles includes a main wash nozzle 11 and a rinsing nozzle 12. A main wash water pump 20 and a rinsing water pump 9 are installed inside the machine body 2.

The rinsing water pump 9 is connected to a cleaning water tank.
[0031] The top cover 1 is equipped with a handle 3 on its exterior. One end of the handle 3 is rotatably connected to the body 2, and the other end is rotatably connected to the top cover 1. This is a conventional design of existing flip-top structures. The top cover 1 can be moved up and down by pulling the handle 3. The top cover 1 is equipped with a fixing tube 19 inside. The lower part of the fixing tube 19 is connected to a fixing plate 27, and the fixing plate 27 is connected to the outer brush head 4.
[0032] The outer brush head 4 has multiple nylon brushes arranged around the center of the tableware 5 to be cleaned, while the inner brush head 13 uses stainless steel wire brushes. Both the nylon brushes and stainless steel wire brushes of the outer brush head 4 and the inner brush head 13 can be designed as detachable structures and can be installed using existing structures such as screws or clips.
[0033] A locking buckle is provided between the top cover 1 and the body 2, which can close and lock the two together.
[0034] The specific working process of this utility model is as follows: 1. Positioning and Start-up: Taking the cleaning of a hot pot as an example, after placing the hot pot with the opening facing down on the rotating pot rack 10, when the top cover 1 is closed, the inner brush head 13 and the outer brush head 4 automatically press the pot body, and the locking buckle locks the top cover 1 in sync, ensuring that the pot does not shift during the cleaning process; after the top cover 1 is completely closed, the main washing program is started, and the equipment enters the automated operation stage.
[0035] II. Core Scrubbing Principle (Coaxial Reverse Motion and Multi-Physical Field Coordination): 1) Bidirectional rotation enhances friction: After the main washing program starts, the four variable speed motors 8 drive the inner brush head 13 to rotate in the forward direction, while the rotating pot rack 10 rotates in the reverse direction, forming a high-speed coaxial and opposite relative motion between the inner brush head 13 and the pot body. This design makes the friction speed between the inner brush head 13 and the surface of the pot superimposed, and with the water flow disturbance, it significantly improves the removal efficiency of food residue, oil stains and other stains on the inner wall of the pot bottom, covering the inner side, outer side and corner areas of the pot.
[0036] 2) Cleaning solution spray assists in stain removal: The main water pump 20 simultaneously sprays cleaning solution into the pot, accelerating the decomposition of stubborn stains and improving the cleaning depth through the dual action of chemical cleaning and mechanical friction.
[0037] III. Rinsing and Cleanliness Guarantee: After the main wash is completed, the equipment automatically switches to the rinsing program: the rinsing water pump 9 sprays 60℃ clean water. The high-temperature water flow can not only rinse away residual cleaning liquid, but also use the temperature to promote the dissolution of grease, ensuring that the cookware is free of chemical residues and meets hygiene standards.
[0038] IV. Material Protection and Lifespan Extension Design: When entering the next cleaning cycle, the variable speed motor 8 automatically switches the rotation direction (i.e., the rotation direction of the brush head and the pot rack are interchanged). This design avoids the "yielding and bending" of the stainless steel wire brush strip due to long-term unidirectional force by alternating the force direction of the inner brush head 13, maintains the elasticity and neatness of the bristles, thereby extending the service life of the brush head strip and ensuring a continuous and stable cleaning effect.
