Kitchen ventilation device

Abstract

The invention discloses a kitchen ventilation device which comprises a kitchen inner wall. Mounting brackets are fixedly mounted at the top and the bottom of the right side of an inner cavity of the kitchen inner wall, a flue gas collecting box is fixedly mounted between the two mounting brackets, the right side of the flue gas collecting box communicates with a main ventilation device, and an exhaust pipeline is arranged in an inner cavity of the flue gas collecting box. During actual use of the kitchen ventilation device, in the ventilation process, if air leakage occurs at the joint of theventilation device, under the action of a flue gas backflow preventing mechanism, backflow flue gas is pumped out again, the flue gas can be exhausted out of a room through an exhaust pipe, and therefore the flue gas is prevented from leaking and flowing back into the room, the purity of indoor air is guaranteed, and convenience is brought to use by a user; and at the time, the user can start a cleaning mechanism to clean a second filter screen to remove oil stains on the second filter screen, cleanness of the second filter screen is guaranteed, and the filtering efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of kitchen ventilation, in particular to a kitchen ventilation device. Background technique [0002] A kitchen is a room in which food is prepared and cooked. A modern kitchen usually includes a stove (gas stove, electric stove, microwave or oven), and a counter (sink or dishwasher). And food storage equipment, it depends on the development of productivity on the one hand, and on the other hand, it also depends on the local natural conditions and the living habits of residents. Through the evolution of different periods, the functionality of the kitchen has gradually become more reasonable. [0003] When the kitchen is in use, there will be oily fumes in the room. At this time, it is necessary to install a ventilation device, but the traditional ventilation device has the following defects: [0004] 1. It is difficult to prevent the backflow of flue gas. When the traditional ventilation device is working, t...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a ventilation device for the kitchen, which has the advantages of being able to prevent backflow of flue gas and prevent oil fume stains from sticking to the inner wall of the pipe, and solves the problem that it is difficult to prevent backflow of smoke. Air often leaks from the joints of the pipes and then flows back into the room, which will greatly reduce the efficiency of ventilation and make it inconvenient for users to use. During long-term use, the stains in the oil fume will stick to the inner wall of the pipes It is difficult to remove, which reduces the effect of ventilation, reduces the speed of ventilation, affects the user experience, and is inconvenient for users to use
