[0001] This utility model relates to the field of dishwasher technology, specifically a dual-rinse device for a commercial dishwasher. Background Technology

[0002] In the commercial dishwasher sector, the rinsing effect of tableware directly affects the hygiene and user experience of subsequent use, especially in the catering industry where high-frequency and large-volume usage scenarios place even stricter requirements on rinsing efficiency and cleanliness.

[0003] In existing technologies, the spray structure is fixed and only the spray angle of the nozzles covers the tableware. However, for tableware with complex shapes or stacked tableware, spray dead corners are easy to occur, resulting in local detergent residue or stains. In addition, the tray on which the tableware is placed remains stationary, and the spray range is still limited by the movement trajectory of the spray pipe, making it difficult to ensure that all surfaces of each piece of tableware are fully in contact with the rinsing water, resulting in poor rinsing uniformity. Utility Model Content

[0004] The purpose of this invention is to provide a dual-rinse device for a commercial dishwasher to solve the problems mentioned in the background art.

Detailed Implementation

[0019] like Figures 1-4As shown, this utility model provides a technical solution: a dual-rinse device for a commercial dishwasher, including a rinsing tank 1. A drain pipe 11 is fixedly connected to the side wall of the rinsing tank 1, and the drain pipe 11 is used to discharge wastewater after rinsing. A horizontal plate 2 is fixedly connected inside the rinsing tank 1, and a placement tray 3 is rotatably connected to the surface of the horizontal plate 2. The horizontal plate 2 serves as the supporting base for the placement tray 3 and also provides a mounting carrier for the rotating assembly 5. The placement tray 3 is used to place the tableware to be rinsed and can rotate with the rotating assembly 5.

[0020] A spray assembly 4 is installed on the inner wall of the rinsing tank 1. The spray assembly 4 uses rotatable spray pipes 42 and nozzles 43 to rinse the tableware on the tray 3 from all directions. The spray assembly 4 includes a toothed ring 41, with two sets of toothed rings symmetrically arranged. The two sets of toothed rings 41 are rotatably connected to the inner walls on both sides of the rinsing tank 1. The toothed rings 41 serve as the support and transmission carrier for the spray pipes 42. Four sets of arrayed spray pipes 42 are fixedly connected between the two sets of toothed rings 41. Nozzles 43 are installed on the outer wall of the spray pipes 42. The spray pipes 42 rotate synchronously with the toothed rings 41 and spray rinsing water through the nozzles 43. A motor 44 is fixedly connected to the side wall of the rinsing tank 1. The output shaft of the motor 44 passes through and is rotatably connected to the inner wall of the rinsing tank 1. A spur gear 45 is fixedly connected to the end of the output shaft of the motor 44. The spur gear 45 meshes with the side wall of the toothed rings 41. After the motor 44 starts, it drives the gear ring 41 to rotate through the spur gear 45, which in turn drives the four sets of spray pipes 42 to rotate around the center of the gear ring 41, so that the nozzles 43 spray in all directions.

[0021] A rotating component 5 is provided on the bottom surface of the horizontal plate 2. The rotating component 5 transmits the power of the spray component 4 to the placement plate 3 through the transmission structure, so that the tableware rotates with the placement plate 3, which in turn improves the uniformity of rinsing in conjunction with the spray component 4. The rotating assembly 5 includes a rotating shaft 51 and a drive shaft 53. The rotating shaft 51 passes through and is rotatably connected to the bottom surface of the horizontal plate 2. The top of the rotating shaft 51 is fixedly connected to the placement tray 3, and the bottom end of the rotating shaft 51 is fixedly connected to a bevel gear 52. The rotating shaft 51 connects the placement tray 3 and the bevel gear 52 together, so that the placement tray 3 and the bevel gear 52 rotate synchronously. The drive shaft 53 passes through and is rotatably connected to the side wall of the rinsing tank 1. One end of the drive shaft 53 is rotatably connected to the inner wall of the rinsing tank 1, and the other end of the drive shaft 53 is fixedly connected to a transmission wheel 54. A bevel gear 55 is fixedly connected to the outer wall of the drive shaft 53. The bevel gear 55 meshes with the bevel gear 52. When the drive shaft 53 rotates, the rotating shaft 51 and the placement tray 3 are driven to rotate through the meshing of the bevel gear 55 and the bevel gear 52.

[0022] The inner wall of the rinsing tank 1 has a through hole, and a connecting shaft 56 is rotatably connected to the through hole. One end of the connecting shaft 56 is fixedly connected to a second spur gear 57, which meshes with the side wall of the gear ring 41. The other end of the connecting shaft 56 is fixedly connected to a second transmission wheel 58, which is connected to a first transmission wheel 54 via a synchronous belt. The connecting shaft 56 connects the second transmission wheel 58 and the second spur gear 57. Through the meshing of the second spur gear 57 with the gear ring 41, the rotation of the gear ring 41 drives the connecting shaft 56 and the second transmission wheel 58 to rotate synchronously. The synchronous belt causes the first transmission wheel 54 to rotate synchronously with the drive shaft 53. The second bevel gear 55 on the drive shaft 53 meshes with the first bevel gear 52 on the rotating shaft 51, ultimately driving the placement tray 3 to rotate.

[0023] In this invention, during use, the tableware to be rinsed is first neatly placed on the placement tray 3, and then the device is started. The motor 44 starts working, and its output shaft drives the first spur gear 45 to rotate. Since the first spur gear 45 meshes with the side wall of the gear ring 41, it drives the two sets of symmetrically arranged gear rings 41 to rotate synchronously on the inner walls on both sides of the rinsing tank 1. As the gear rings 41 rotate, the four arrayed spray pipes 42 fixedly connected between the two sets of gear rings 41 also rotate around the center of the gear rings 41. The nozzles 43 on the outer wall of the spray pipes 42 will spray and rinse the tableware on the placement tray 3 from all directions and at multiple angles. At the same time, the rotation of the gear rings 41 will also drive the second spur gear 57, which meshes with it, to rotate. The second spur gear 57 is fixed to one end of the connecting shaft 56, so the connecting shaft 56 will rotate together with the second spur gear 57, thereby causing the second transmission wheel 58 at the other end of the connecting shaft 56 to rotate synchronously. Since the second transmission wheel 58 is connected to the first transmission wheel 54 at the other end of the drive shaft 53 via a synchronous belt, the first transmission wheel 54 drives the drive shaft 53 to rotate on the side wall of the rinsing tank 1. When the drive shaft 53 rotates, the second bevel gear 55 fixed on its outer wall also rotates. Because the second bevel gear 55 meshes with the first bevel gear 52 at the bottom of the rotating shaft 51, it drives the rotating shaft 51 to rotate on the bottom surface of the horizontal plate 2. The top of the rotating shaft 51 is fixedly connected to the placement tray 3, so the placement tray 3 rotates with the rotating shaft 51, allowing the tableware on the placement tray 3 to continuously change position and better contact the rinsing water sprayed from the nozzle 43. During the entire rinsing process, the wastewater generated during rinsing is discharged through the drain pipe 11 on the side wall of the rinsing tank 1. By coordinating the rotating spray of the spray assembly 4 with the rotation of the placement tray 3, a double rinsing of the tableware is achieved, effectively improving the rinsing effect and efficiency, and ensuring that the tableware is cleaned more thoroughly.

[0024] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
