Technical Field
[0001] This utility model relates to the field of kitchen purification equipment technology, and in particular to a commercial kitchen multi-station integrated oil fume purification machine. Background Technology
[0002] Multi-station integrated kitchen fume purification units, as a highly efficient kitchen fume treatment device, have been widely used in large catering enterprises, canteens, and other places where multiple stoves operate simultaneously. In order to effectively purify the large amount of oil fumes generated during cooking and prevent the spread of oil fumes from adversely affecting the kitchen environment, the health of staff, and the surrounding air quality, mainstream commercial multi-station integrated kitchen fume purification units on the market all have highly efficient oil fume separation and purification functions.
[0003] The multi-station integrated kitchen fume purification unit mainly consists of a fan system, a purification module, an exhaust duct, and an intelligent control system. Its working principle is that when the fan system starts running, it generates negative pressure. Under the action of negative pressure, the fume collection hood quickly captures the cooking fumes generated at each station. Due to the airflow difference between the collection hood and the purification module, the fumes continuously enter the purification module from the collection hood. After passing through multiple purification processes such as primary filtration, electrostatic separation, and activated carbon adsorption, the purified clean air is discharged outdoors through the exhaust duct.
[0004] When using existing multi-station integrated kitchen fume purification machines, the exhaust pipes of some units become narrowed and the exhaust resistance increases due to long-term accumulation of grease and dirt without timely cleaning. This not only prevents the fumes from being discharged quickly, but also allows grease to continue to adhere to the inner wall of the exhaust vent, further aggravating the blockage problem. At the same time, the grease residue may cause malfunctions such as adhesion of exhaust vent components and abnormal operating noises, affecting the overall exhaust efficiency and service life of the equipment. Therefore, a commercial kitchen multi-station integrated kitchen fume purification machine is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a commercial kitchen multi-station oil fume purification integrated machine, which aims to improve the problem of oil sludge accumulating in the exhaust pipe and being unable to be cleaned in the existing technology.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A commercial kitchen multi-station oil fume purification integrated machine includes a body, a fixing ring fixedly connected to the top of the body, an exhaust vent fixedly connected to the top of the body, a cleaning mechanism inside the exhaust vent, and an auxiliary mechanism inside the body. The cleaning mechanism includes a rotating column, the front end of which is rotatably connected to the inside of the exhaust port, and multiple fixed columns are fixedly connected to the outside of the rotating column. An inclined plate is fixedly connected to the right end of each of the multiple fixed columns. A scraping assembly is provided on the outside of the rotating column, and a fixed plate is rotatably connected to the rear end of the rotating column. A stud is threaded onto the outside of the fixed plate. As a further description of the above technical solution: The auxiliary mechanism includes a telescopic column, the rear end of which is fixedly connected to the inside of the machine body. A spring is sleeved on the outside of the telescopic column. A fixing block is fixedly connected to the front end of the telescopic column. A limit post is fixedly connected to the front end of the fixing block. A brush plate is slidably connected to the front end of the limit post. A control block is fixedly connected to the outside of the brush plate. A connecting post is fixedly connected to the left end of the limit post. A sliding block is fixedly connected to the left end of the connecting post. As a further description of the above technical solution: The scraping assembly includes a connecting plate, the right end of which is fixedly connected to the left end of the rotating column, and the left end of which is fixedly connected to a scraping plate. As a further description of the above technical solution: The stud is externally threaded to the outside of the exhaust port, and the outside of the scraper plate is in contact with the inside of the exhaust port; As a further description of the above technical solution: Multiple fixed columns are arranged in an array outside the rotating column, and the outside of the fixed columns is rotatably connected to the inside of the exhaust port; As a further description of the above technical solution: The outer side of the body is provided with a sliding groove, and the outer side of the connecting column is slidably connected to the inside of the sliding groove; As a further description of the above technical solution: The brush plate is externally slidably connected to the inside of the machine body, and the sliding block is slidably connected to the left end of the machine body; As a further description of the above technical solution: One end of the spring is fixedly connected to the inside of the machine body, and the other end of the spring is fixedly connected to the rear end of the fixing block.
[0007] This utility model has the following beneficial effects: 1. In this utility model, when gas is output through the exhaust port, the inclined plate moves with the gas, thereby driving the rotating column to rotate. Simultaneously, the rotating column rotates, causing the connecting plate in the scraping assembly to rotate synchronously. The connecting plate, in turn, drives the scraper plate fixed to it to rotate. During the rotation of the scraper plate, accumulated oil stains on the inner wall of the exhaust port can be cleaned in a timely manner, and the oil stains are discharged with the gas output. When the scraper plate needs cleaning or replacement of the cleaning mechanism after a period of use, rotating the stud can disconnect the threaded connection between the exhaust port and the fixed plate. The fixed plate is fixed to the rear end of the rotating column. At this time, dragging the fixed plate allows the cleaning mechanism to slide out from inside the exhaust port.
[0008] 2. In this utility model, by controlling the sliding block, the connecting column is made to slide, which in turn causes the limiting column fixed to the connecting column to move the fixing block to the rear end, thereby causing the telescopic column to extend and retract to the rear end and compress the spring. When the limiting column slides to the designated position and slides out of the brush plate, the brush plate can be removed by dragging the control block. The oil stains at the air intake can be cleaned through the brush plate. Attached Figure Description

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0012] Commercial kitchen multi-station fume purification unit, refer to Figures 1 to 3 The system includes a body 1, which can absorb and treat oil fumes. A fixing ring 2 is fixedly connected to the top of the body 1. The fixing ring 2 is used to seal the connection between the body 1 and the exhaust port 3 to prevent the treated gas from leaking from the connection. A sliding groove is provided on the outside of the body 1. The sliding groove provides a guide path for the sliding of the connecting column 57 to ensure the stable movement of the connecting column 57. The outside of the connecting column 57 is slidably connected to the inside of the sliding groove. The connecting column 57 can drive the movement of subsequent components by sliding in the sliding groove. An exhaust port 3 is fixedly connected to the top of the body 1. The exhaust port 3 is the discharge channel for the treated normal gas, which guides the gas treated by the body 1 to the outside. A cleaning mechanism 4 is provided inside the exhaust port 3. The cleaning mechanism 4 is used to remove the oil stains accumulated on the inner wall of the exhaust port 3 to avoid the oil stains clogging the exhaust port 3 and affecting the exhaust efficiency. An auxiliary mechanism 5 is provided inside the body 1. The auxiliary mechanism 5 can clean the oil stains at the air intake of the body 1 to reduce the oil stains splashing into the inside of the body 1 and causing damage to the body 1. The cleaning mechanism 4 includes a rotating column 41, which is the rotating component of the cleaning mechanism 4. The front end of the rotating column 41 is rotatably connected to the inside of the exhaust port 3. This connection allows the rotating column 41 to rotate stably inside the exhaust port 3. Multiple fixed columns 42 are fixedly connected to the outside of the rotating column 41. The multiple fixed columns 42 are arranged in an array outside the rotating column 41. The fixed columns 42 are used to connect the rotating column 41 and the inclined plate 43, and transmit the force on the inclined plate 43 to the rotating column 41. The external connection of the fixed columns 42 to the inside of the exhaust port 3 further enhances the stability of the rotating column 41 during rotation. The right end of each of the multiple fixed columns 42 is fixedly connected to the inclined plate 43. The inclined plate 43 can move with the gas when the exhaust port 3 outputs gas, thereby driving the rotating column 41 to rotate. A scraping assembly 44 is provided on the outside of the rotating column 41. The scraping assembly 44 is the execution component for cleaning the oil stains on the inner wall of the exhaust port 3. The scraping assembly 44 includes a connecting plate 441, which connects the rotating column 41 and the scraper 442. The right end of the connecting plate 441 is fixedly connected to the left end of the rotating column 41, allowing the connecting plate 441 to rotate synchronously with the rotating column 41. The left end of the connecting plate 441 is fixedly connected to the scraper 442, which directly contacts the inner wall of the exhaust port 3 for scraping and cleaning. The outer surface of the scraper 442 contacts the inner surface of the exhaust port 3. As the scraper 442 rotates, it can promptly clean the oil stains accumulated on the inner wall of the exhaust port 3, which are then discharged with the gas output. The rear end of the rotating column 41 is rotatably connected to a fixed plate 45. The fixed plate 45 is used to limit and fix the rear end of the rotating column 41, and at the same time facilitates the overall disassembly of the cleaning mechanism 4. The fixed plate 45 is externally threaded with a stud 46. The stud 46 is the component that connects and fixes the fixed plate 45 to the exhaust port 3. The external thread of the stud 46 is connected to the outside of the exhaust port 3. When the scraper 442 needs to be cleaned or replaced after a period of use, rotating the stud 46 can cancel the threaded connection between the exhaust port 3 and the fixed plate 45, thereby dragging the fixed plate 45 to make the cleaning mechanism 4 slide out of the exhaust port 3.
[0013] Specifically, the cleaning mechanism 4 includes a rotating column 41, which is rotatably installed inside the exhaust port 3. A fixed column 42 is fixed to the outside of the rotating column 41, and an inclined plate 43 is fixed to the right end of the fixed column 42. When the exhaust port 3 outputs gas, the inclined plate 43 moves with the gas, thereby driving the rotating column 41 to rotate. Simultaneously, the rotating column 41 drives the connecting plate 441 in the scraping assembly 44 to rotate synchronously. The connecting plate 441, in turn, drives the scraper plate 442 fixed to it to rotate. During the rotation of the scraper plate 442, it can promptly clean the oil stains accumulated on the inner wall of the exhaust port 3 and allow the oil stains to be discharged with the gas output. When the scraper plate 442 needs to be cleaned or the cleaning mechanism 4 replaced after a period of use, rotating the stud 46 can disconnect the threaded connection between the exhaust port 3 and the fixed plate 45. The fixed plate 45 is fixed to the rear end of the rotating column 41. At this time, dragging the fixed plate 45 will slide the cleaning mechanism 4 out of the exhaust port 3.
[0014] Reference Figure 1 , Figure 2 and Figure 4The auxiliary mechanism 5 includes a telescopic column 51, which provides guidance and support for the forward and backward movement of the fixed block 53. The rear end of the telescopic column 51 is fixedly connected to the inside of the body 1, ensuring that the telescopic column 51 can be stably installed inside the body 1 and guaranteeing the reliability of the telescopic movement. A spring 52 is sleeved on the outside of the telescopic column 51. The spring 52 uses its own elastic deformation to achieve the reset function of the fixed block 53. One end of the spring 52 is fixedly connected to the inside of the body 1, providing a fixed support end point for the spring 52, and the other end of the spring 52 is fixedly connected to... The spring 52 is attached to the rear end of the fixed block 53 so that it can stretch and deform with the movement of the fixed block 53 and store elastic potential energy. The front end of the telescopic column 51 is fixedly connected to the fixed block 53. The fixed block 53 is used to connect the telescopic column 51 and the limiting column 54 and plays the role of force transmission. The front end of the fixed block 53 is fixedly connected to the limiting column 54. The limiting column 54 achieves the fixing and unlocking of the brush plate 55 through cooperation with the brush plate 55. The front end of the limiting column 54 is slidably connected to the brush plate 55. The brush plate 55 is the part in the auxiliary mechanism 5 that directly cleans the oil stains of the air intake. The brush plate 55 is externally slidably connected to the inside of the body 1, allowing the brush plate 55 to slide stably within the body 1 for easy removal for cleaning or installation and fixation. A control block 56 is fixedly connected to the outside of the brush plate 55, providing a gripping area for the operator to easily drag the brush plate 55 for picking up and putting it down. A connecting post 57 is fixedly connected to the left end of the limiting post 54, which connects the limiting post 54 and the sliding block 58 to achieve synchronous movement of the two. A sliding block 58 is fixedly connected to the left end of the connecting post 57, which is the operating component for the operator to control the action of the auxiliary mechanism 5. The sliding block 58 is slidably connected to the left end of the body 1, allowing the operator to drive the movement of subsequent components by sliding the sliding block 58, thereby unlocking and fixing the brush plate 55.
[0015] Specifically, the sliding block 58 is controlled to move the connecting post 57, which in turn causes the limiting post 54, fixed to the connecting post 57, to move the fixing block 53 to the rear end. This process causes the telescopic post 51 to extend and retract to the rear end, compressing the spring 52. When the limiting post 54 slides to the designated position and out of the brush plate 55, the brush plate 55 can be removed by dragging the control block 56. The brush plate 55 can be used to clean oil stains at the air intake. After the brush plate 55 is used, it is dragged in the same way to slide into the machine body 1. The compressed spring 52 will push the fixing block 53 in the opposite direction, allowing the limiting post 54 to slide into the brush plate 55, thus completing the fixation of the brush plate 55.
[0016] The implementation principle of this application embodiment is as follows: The commercial kitchen multi-station oil fume purification integrated machine is composed of a body 1, a fixing ring 2, and an exhaust port 3. The top of the body 1 is fixed with a fixing ring 2 and an exhaust port 3. The fixing ring 2 is used to seal the connection between the body 1 and the exhaust port 3. When using the commercial kitchen multi-station oil fume purification integrated machine, the body 1 is started. The body 1 can absorb and process the oil fume generated at the bottom of the body 1 into normal gas, which is then discharged through the exhaust port 3.
[0017] The exhaust vent 3 has a cleaning mechanism 4 inside for removing oil and grease buildup on its inner wall. The cleaning mechanism 4 includes a rotating column 41, which rotates inside the exhaust vent 3. A fixed column 42 is fixed to the outside of the rotating column 41. An inclined plate 43 is fixed to the right end of the fixed column 42. The inclined plate 43 moves with the gas flow when the exhaust vent 3 outputs gas, thereby driving the rotating column 41 to rotate. Simultaneously, the rotation of the rotating column 41 drives the connecting plate 441 in the scraping assembly 44 to rotate synchronously, thus... The scraper 442, which is fixed to the connecting plate 441, rotates. As the scraper 442 rotates, it can clean the oil stains accumulated on the inner wall of the exhaust port 3 in a timely manner and discharge them with the gas output. When the scraper 442 has been used for a period of time, and the cleaning mechanism 4 needs to be cleaned or replaced, the screw 46 can be rotated to cancel the threaded connection between the exhaust port 3 and the fixed plate 45. The fixed plate 45 is fixed to the rear end of the rotating column 41, so that the fixed plate 45 can be dragged, thereby allowing the cleaning mechanism 4 to slide out of the interior of the exhaust port 3.
[0018] The auxiliary mechanism 5 can clean the oil stains at the air intake of the machine body 1, reducing the oil stains from splashing into the interior of the machine body 1 and causing damage to the machine body 1. Specifically, the sliding block 58 is controlled to drive the connecting column 57 to slide, which in turn causes the limiting column 54 fixed to the connecting column 57 to drive the fixing block 53 to move to the rear end, thereby causing the telescopic column 51 to extend and retract to the rear end and compress the spring 52. When the limiting column 54 slides to the designated position and slides out of the brush plate 55, the brush plate 55 can be removed by dragging the control block 56. The oil stains at the air intake can be cleaned by the brush plate 55. After the brush plate 55 is used, similarly, the brush plate 55 is dragged to slide into the interior of the machine body 1. The compressed spring 52 pushes the fixing block 53 in the opposite direction, causing the limiting column 54 to slide into the interior of the brush plate 55, thereby completing the fixation of the brush plate 55.
[0019] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
