Maintenance device for household range hood

Abstract

The invention relates to the technical field of household appliances, and discloses a maintenance device for a household range hood. The maintenance device comprises a main body frame, rotating partsare arranged on the left portion and the right portion of the main body frame, driving wheels are arranged behind the rotating parts, driven wheels are arranged on the left portions of the driving wheels, toothed frames are connected to the lower portions of the driven wheels in a meshing mode, rotating wheels are connected to the lower surfaces of the toothed frames in a meshing mode, toothed plates are connected to the lower surfaces of the rotating wheels in a meshing mode, and elastic oil absorption blocks are fixedly connected to the lower surfaces of the toothed plates. According to themaintenance device, when the rotating parts rotate, the driving wheels are driven to rotate, the toothed plates drive the elastic oil absorption blocks to get close to the lower portion of a filter screen, oil stains on the filter screen are absorbed and cleared in the getting-close process, the elastic oil absorption blocks are extruded together to extrude the absorbed oil stains out and drip theabsorbed oil stains downwards into an oil collection box, after the driven wheels are separated from the toothed frames, the elastic oil absorption blocks are driven to return to the initial positions under the tension of reset springs, and therefore through the structure, the effect of automatically clearing the oil stains on the surface of the filter screen can be achieved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a maintenance device for a household range hood. Background technique [0002] Cooking is a way of processing food. During the cooking process, a lot of oily fume will be produced. The appearance of the range hood has solved the problem of cooking fume. Although the range hood can absorb and remove a large amount of oil fume, the range hood The following problems still exist during use: a large amount of oil will adhere to the internal filter of the range hood, and if it is not cleaned in time, it will affect the filtering effect; oil will adhere to the chimney, and long-term accumulation will cause the chimney to block; The oil will flow into the oil drain box at the bottom of the hood. The oil drain box has a limited volume and will overflow when it is full, causing pollution. In order to solve the above problems, a maintenance device for a household range hood is...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the existing technology, the invention provides a maintenance device for household range hoods, which can automatically clean the oil on the surface of the filter screen, so that the filter screen can maintain the filtering effect, and use the rapid flow of gas to remove the sundries inside the chimney. The advantages of extracting and cleaning the oil in the oil drain box, so that the oil in the oil drain box will not overflow to pollute the environment, solve the problem that a large amount of oil stains will adhere to the filter and affect the filtering effect, the chimney will be blocked, and the oil spill will pollute the oil drain box environmental problems
