Household kitchen ventilation device based on fresh air circulation

Abstract

The invention discloses a household kitchen ventilation device based on fresh air circulation. The household kitchen ventilation device includes an air exhaust mechanism for discharging kitchen fumes,the output end of the air exhaust mechanism is connected with a filter protection assembly, and a multi-direction fresh air inlet mechanism is connected to the outside of a kitchen; the air exhaust mechanism includes a lampblack bucket installed at the top end of the kitchen, a filter oil collecting bucket is installed inside the lampblack bucket, an annular air inlet net is installed between thefilter oil collecting bucket and the lampblack bucket, and the lampblack bucket is connected with a exhaust pipe through a centrifugal fan; and the filter protection assembly includes a screen seat connected at the tail end of the exhaust pipe, the top end of the screen seat is connected with a sunshade seat through a guide pipe, the side face of the screen seat is connected with a plurality of sunshade plates, the side face of the guide pipe is connected with a plurality of air outlet pipes, and the tail end of the air outlet pipe is connected with vertical dustproof seats. According to thehousehold kitchen ventilation device based on fresh air circulation, lampblack air inside the kitchen is extracted through the air exhaust mechanism and residual lampblack is centralized and filtered,at the same time, comprehensive aeration and ventilation of the kitchen through the multi-directional fresh air inlet mechanism are achieved, and the air ventilation property is improved.

Description

technical field [0001] The invention relates to the technical field of kitchen ventilation, in particular to a ventilation device for a family kitchen based on fresh air circulation. Background technique [0002] A kitchen is a room in which food is prepared and cooked.

Problems solved by technology

[0006] (1) Since the exhaust end of the general kitchen ventilation device is directly exposed to the outside, after long-term use, it is easy to cause blockage of the air outlet, and under the action of high temperature irradiation, it is easy to produce peculiar smell;

[0007] (2) Moreover, when the fresh air circulation is realized, the external air is directly discharged into the kitchen, resulting in slow diffusion of fresh air in the kitchen and poor ventilation effect
