Description

Technical Field

[0001] This utility model relates to the field of range hood cleaning technology, and in particular to a range hood with automatic surface cleaning. Background Technology

[0002] As an indispensable kitchen appliance, the core function of a range hood is to exhaust cooking fumes, moisture, and harmful gases generated during cooking to the outside through its suction and exhaust system, effectively improving kitchen air quality.

[0003] During long-term use, a large amount of oil and smoke stains easily accumulate on the surface of the range hood's oil and smoke separation mesh. These stains are mainly composed of a mixture of grease, dust, and water vapor, and are characterized by strong stickiness and adhesion.

[0004] Existing devices mostly require manual cleaning of the outer surface of the oil fume separation mesh. Since the range hood is installed in a high position, cleaning requires tiptoeing or the use of tools, which not only increases the user's housework burden, but also makes it easy for users to slip or get scratched when they come into contact with the greasy mesh and cleaning agents. Therefore, we propose a range hood with automatic surface cleaning to solve the above problems. Utility Model Content

[0005] The main purpose of this invention is to provide a range hood with automatic surface cleaning, which can effectively solve the above problems.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A range hood with automatic surface cleaning includes a range hood body, a drain pipe fixedly connected to the left end of the range hood body, an oil fume separation mesh fixedly connected to the inner wall of the range hood body, a cleaning component inside the range hood body, and an anti-splash component on the front of the range hood body.

[0008] Preferably, the cleaning component includes two threaded rods, the left and right outer surfaces of the two threaded rods are rotatably connected to the inner wall of the range hood body, a motor is fixedly connected to the right end of the range hood body, the output end of the motor is fixedly connected to the right end of the threaded rod located above, and a spray mechanism is installed on the top of the range hood body.

[0009] Preferably, the left ends of both threaded rods are fixedly connected to pulleys, and the outer surfaces of the two pulleys are connected to a belt for transmission.

[0010] Preferably, the outer surfaces of the two threaded rods are threadedly connected to a movable plate, and the inner wall of the movable plate is slidably connected to two sliding rods. The back of the two sliding rods is fixedly connected to a cleaning plate, and the back of the cleaning plate is in close contact with the front of the oil fume separation mesh.

[0011] Preferably, a spring is sleeved on the outer surface of each of the two slide rods, the back of each of the two springs is fixedly connected to the front of the cleaning plate, and the front of each of the two springs is fixedly connected to the back of the moving plate.

[0012] Preferably, the anti-splash assembly includes a baffle, the back of which is in close contact with the front of the range hood body, and two connecting plates are fixedly connected to the back of the baffle. The range hood body has slots on both the left and right ends, and the inner walls of the two slots are slidably connected to the outer surface of the connecting plates on the same side.

[0013] Preferably, the range hood body is fixedly connected to a mounting bracket at both the left and right ends. The two mounting brackets are arranged symmetrically with the center of the range hood body as the center point. A sliding rod is slidably connected to the inner wall of the mounting bracket. A locking block is fixedly connected to the end of the sliding rod near the range hood body. Insertion holes are opened at the ends of the two connecting plates that are far apart from each other. The outer surface of the locking block near the range hood body is inserted into the inner wall of the insertion hole on the same side.

[0014] Preferably, a second spring is sleeved on the outer surface of the sliding rod, and the end of the second spring near the range hood body is fixedly connected to the end of the locking block away from the range hood body on the same side, and the end of the second spring away from the range hood body is fixedly connected to the outer surface of the fixing frame on the same side.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This utility model, by setting up a cleaning component, specifically sprays cleaning liquid onto the outer surface of the oil fume separation net through a spraying mechanism. Turning on the motor drives the moving plate to move, and when the moving plate moves, it will drive the cleaning plate to move on the surface of the oil fume separation net, so that the surface of the oil fume separation net can be automatically cleaned without the need for manual cleaning by the user. This not only greatly reduces the user's housework burden, but also eliminates the need for manual contact with the greasy net and cleaning agent, reducing the occurrence of accidents such as slipping and scratches.

[0017] 2. This utility model incorporates a splash-proof component, specifically by installing a baffle on the front of the range hood body. A spring pushes a locking block to insert into the inner wall of the corresponding socket, thus fixing the baffle to the front of the range hood body. This prevents cleaning liquid from splashing everywhere when cleaning the oil fume separator. It not only avoids the need for additional wiping and cleaning of the stove, countertop, floor, or walls, but also keeps the kitchen clean and orderly during and after cleaning. Furthermore, it eliminates the need to be distracted or cover surrounding items in advance, simplifying the cleaning process and improving cleaning efficiency. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Example 1, as Figure 1-6 As shown, a range hood with automatic surface cleaning includes a range hood body 1, a drain pipe 11 fixedly connected to the left end of the range hood body 1, an oil fume separation net 12 fixedly connected to the inner wall of the range hood body 1, a cleaning component 2 disposed inside the range hood body 1, and a splash-proof component 3 disposed on the front of the range hood body 1.

[0027] Specifically, in order to achieve the goal of automatically cleaning the surface of the oil fume separation mesh, please refer to... Figure 2 and Figure 3 In this embodiment, the cleaning component 2 includes two threaded rods 21. The left and right outer surfaces of the two threaded rods 21 are rotatably connected to the inner wall of the range hood body 1. A motor 211 is fixedly connected to the right end of the range hood body 1. The output end of the motor 211 is fixedly connected to the right end of the threaded rod 21 located above. A spraying mechanism 22 is installed on the top of the range hood body 1.

[0028] The aforementioned spraying mechanism 22 includes a water tank, a water pump, two water pipes, and a spray box. When the device is in use, the water pump is turned on to transport the cleaning liquid inside the water tank to the inside of the spray box through the two water pipes. The cleaning liquid entering the spray box will be sprayed onto the surface of the oil fume separation net 12 through several nozzles at its bottom.

[0029] Further reading Figure 3 In this embodiment, the left ends of the two threaded rods 21 are fixedly connected to pulleys 23, and the outer surfaces of the two pulleys 23 are connected to belts 231 for transmission.

[0030] Further reading Figure 3 and Figure 4 In this embodiment, the outer surfaces of the two threaded rods 21 are threadedly connected to a movable plate 24. The inner wall of the movable plate 24 is slidably connected to two slide rods 241. The back sides of the two slide rods 241 are fixedly connected to a cleaning plate 242. The back side of the cleaning plate 242 is in close contact with the front side of the oil fume separation mesh 12.

[0031] During implementation, the cleaning liquid is sprayed onto the outer surface of the oil fume separation mesh 12 through the spraying mechanism 22. The motor 211 is turned on to drive the upper threaded rod 21 to rotate. When the threaded rod 21 rotates, it drives the belt pulley 23 to rotate. When the belt pulley 23 rotates, it drives the lower belt pulley 23 to rotate through the belt 231. This allows the two threaded rods 21 to rotate simultaneously within the inner wall of the range hood body 1. The rotation of the two threaded rods 21 also drives the moving plate 24 to move. When the moving plate 24 moves, it drives the cleaning plate 242 to move on the surface of the oil fume separation mesh 12, so that the surface of the oil fume separation mesh 12 can be automatically cleaned without the need for manual cleaning by the user. This not only greatly reduces the user's housework burden, but also eliminates the need for manual contact with the greasy mesh and cleaning agent, reducing the occurrence of accidents such as slipping and scratches.

[0032] Further reading Figure 4 In this embodiment, springs 243 are sleeved on the outer surfaces of both slide rods 241, the backs of both springs 243 are fixedly connected to the front of the cleaning plate 242, and the fronts of both springs 243 are fixedly connected to the back of the moving plate 24.

[0033] When the cleaning plate 242 wears down due to prolonged use, the two deformed springs 243 will push the cleaning plate 242 to the back due to elasticity, so that the cleaning plate 242 can always stick tightly to the front of the oil fume separation net 12.

[0034] The cleaning surface of the aforementioned cleaning plate 242 is made of soft and wear-resistant synthetic material Alcantara. This is a synthetic fabric that is soft and delicate to the touch, wear-resistant and has good tensile strength. Even if it comes into frequent contact and friction with the oil fume separation mesh, it is not easy to cause scratches or damage to it.

[0035] Example 2: This example is based on Example 1 and includes an anti-splashing component.

[0036] Specifically, in order to avoid cleaning solution splashing everywhere during cleaning, refer to... Figure 5 and Figure 6 In this embodiment, the anti-splash component 3 includes a baffle 31. The back of the baffle 31 is in close contact with the front of the range hood body 1. Two connecting plates 32 are fixedly connected to the back of the baffle 31. The left and right ends of the range hood body 1 are provided with slots. The inner walls of the two slots are slidably connected to the outer surface of the connecting plate 32 on the same side.

[0037] Further reading Figure 6 In this embodiment, a fixing bracket 33 is fixedly connected to both the left and right ends of the range hood body 1. The two fixing brackets 33 are arranged symmetrically with the center of the range hood body 1 as the left and right. A sliding rod 331 is slidably connected to the inner wall of the fixing bracket 33. A locking block 332 is fixedly connected to the end of the sliding rod 331 near the range hood body 1. Insertion holes are opened at the ends of the two connecting plates 32 that are far apart from each other. The outer surface of the locking block 332 near the range hood body 1 is inserted into the inner wall of the insertion hole on the same side.

[0038] Further reading Figure 6 In this embodiment, a second spring 333 is sleeved on the outer surface of the sliding rod 331. The end of the second spring 333 near the range hood body 1 is fixedly connected to the end of the locking block 332 on the same side away from the range hood body 1. The end of the second spring 333 away from the range hood body 1 is fixedly connected to the outer surface of the fixing frame 33 on the same side.

[0039] During implementation, when cleaning the surface of the oil fume separation mesh 12 is required, the baffle 31 is first installed on the front of the range hood body 1. Simultaneously, the installation of the baffle 31 causes the two connecting plates 32 to insert into their corresponding slots and move backward. After moving a certain distance, the back of the connecting plate 32 contacts the locking block 332. Since both the contact surfaces of the connecting plate 32 and the locking block 332 are angled, the continuous movement of the connecting plate 32 pushes the locking block 332 away from the center of the range hood body 1. As the locking block 332 moves, it causes the sliding rod 331 to slide within the inner wall of the corresponding fixing bracket 33. As block 332 moves, it also compresses spring 333, causing it to deform. After connecting plate 32 is inserted, the deformed spring 333 will push block 332 into the inner wall of the corresponding socket due to its elasticity, so that baffle 31 can be fixed on the front of range hood body 1. This can prevent cleaning liquid from splashing everywhere when cleaning oil fume separation mesh 12. It not only avoids the need for additional wiping and cleaning work on stove, countertop, floor or wall, but also keeps the kitchen clean and orderly during and after cleaning. Moreover, there is no need to be distracted or cover the surrounding items in advance, simplifying the cleaning process and improving cleaning efficiency.

[0040] The sprayed cleaning liquid will be blocked by the baffle 31 and fall into the bottom of the inner wall of the range hood body 1, and then discharged to the outside through the drain pipe 11.

[0041] The working principle of this utility model is as follows: When it is necessary to clean the surface of the oil fume separation mesh 12, the baffle 31 is first installed on the front of the range hood body 1. At the same time as the baffle 31 is installed, it will drive the two connecting plates 32 to be inserted into the corresponding slots and move to the back. After the connecting plates 32 move a certain distance, their backs will contact the card block 332. Since the contact surfaces of the connecting plates 32 and the card block 332 are both set at an angle, as the connecting plates 32 continue to move, they will push the card block 332 to move away from the center of the range hood body 1. When the card block 332 moves, it will drive the sliding rod 331 to slide in the inner wall of the corresponding fixing frame 33. As the locking block 332 moves, it also compresses the second spring 333, causing it to deform. After the connecting plate 32 is inserted, the deformed second spring 333 will push the locking block 332 into the inner wall of the corresponding socket due to its elasticity, so that the baffle 31 can be fixed on the front of the range hood body 1. This can prevent the cleaning liquid from splashing everywhere when cleaning the oil fume separation net 12. It not only avoids the extra wiping and cleaning work on the stove, countertop, floor or wall, but also keeps the kitchen clean and orderly during and after cleaning. Moreover, there is no need to be distracted or cover the surrounding items in advance, which simplifies the cleaning process and improves cleaning efficiency.

[0042] After the baffle 31 is installed, the cleaning liquid is sprayed onto the outer surface of the oil fume separation mesh 12 through the spray mechanism 22. The motor 211 is turned on to drive the upper threaded rod 21 to rotate. When the threaded rod 21 rotates, it drives the belt pulley 23 to rotate. When the belt pulley 23 rotates, it drives the lower belt pulley 23 to rotate through the belt 231. This allows the two threaded rods 21 to rotate simultaneously in the inner wall of the range hood body 1. The rotation of the two threaded rods 21 also drives the moving plate 24 to move. When the moving plate 24 moves, it drives the cleaning plate 242 to move on the surface of the oil fume separation mesh 12, so that the surface of the oil fume separation mesh 12 can be automatically cleaned without the need for manual cleaning by the user. This not only greatly reduces the user's housework burden, but also eliminates the need for manual contact with the greasy mesh and cleaning agent, reducing the occurrence of accidents such as slipping and scratches.
