Description

Technical Field

[0001] This utility model relates to the field of range hood technology, specifically to a range hood that is easy to clean. Background Technology

[0002] Traditional range hoods have long faced cleaning challenges. The grease filter is easily clogged with grease and is cumbersome to disassemble. The complex internal structure leads to grease buildup that is difficult to clean, requiring frequent professional cleaning. Existing designs often suffer from small grease cup capacity, leading to easy grease overflow, or numerous hard-to-reach crevices and corners that are difficult for cleaning tools to access, increasing user maintenance costs and time. Furthermore, the grease filter and panel materials are highly adhesive to grease, requiring large amounts of cleaning agents, which reduces cleaning efficiency and may cause secondary pollution. Therefore, developing a tool-free, quick-disassembly, grease-resistant, easy-to-wash range hood structure with no cleaning dead spots is crucial for improving user experience and equipment durability.

[0003] Chinese patent document CN213453788U discloses a range hood that is easy to clean. It includes a range hood body, a smoke extraction box fixedly connected to the top of the back side of the range hood body, an exhaust pipe connected to the top of the smoke extraction box, slots on both sides of the inner wall of the range hood body, a filter body installed on the front side of the range hood body, and fixed boxes fixedly connected to both sides of the filter body. This invention uses a rotating plate to drive a smooth rod to rotate inside the fixed boxes. The rotation of the smooth rod drives a turntable to rotate, which in turn moves a movable rod. The rotation of the movable rod pulls a vertical plate inward, which in turn moves a moving rod. The moving rod pulls a locking block out of the slot, achieving the advantage of easy cleaning. This solves the problem of existing range hoods being inconvenient to clean during use, often involving cumbersome filter removal, which hinders quick removal and affects cleaning effectiveness.

[0004] Although the device described in the aforementioned literature allows for easy disassembly of the filter, its structure is relatively simple, and its cleaning effect is still insufficient. The constant disassembly and cleaning adds to the user's cleaning burden, and the oil can connection is not convenient enough, causing trouble for the user and reducing the practical value of the device.

A rotating roller drives a belt to circulate, causing the brush plates to move reciprocally or unidirectionally, continuously rubbing the filter surface and removing grease in real time. This avoids the tedious process of traditional manual cleaning. Cleaning is completed simultaneously while the device is running, eliminating the need for frequent shutdowns to disassemble the filter, ensuring continuous operation of the range hood. It is particularly suitable for high-frequency usage scenarios such as restaurants. The brush plates effectively remove stubborn grease through mechanical friction, preventing filter pore blockage, maintaining fume extraction efficiency, and reducing fan overload or increased noise caused by filter blockage. Automated cleaning avoids problems such as uneven cleaning force, filter deformation, or improper installation during manual cleaning, ensuring consistent cleaning results. Rotating the manual lever causes the first rotating roller to rotate, causing the second rotating roller connected by a synchronous pulley to rotate as well. The operation of both causes the brush plates on the belt to move, thereby using friction to scrub the first filter. Attached Figure Description
