Circulation air cooker

Abstract

The invention discloses a circulation air cooker, comprising a cooker cabinet, a fan for providing airflow power and an airflow filtering device, wherein the cooker cabinet is composed of a hearth for the placement of stoves and a hood provided with an air suction port; the hood is connected with the air suction port of the fan through an air inlet duct, the airflow filtering device comprises a primary filtering device which is arranged inside the air inlet duct; the airflow filtering device further comprises a wet filtering device for performing secondary filtering on the airflow which is filtered by the primary filtering device, and the airflow carrying cooking fume is subjected to primary filtering and wet filtering and then delivered to an air exhausting port through an air returning duct to be directly exhausted out of the cooker and to working environment or outdoor atmosphere. The circulation air cooker can recycle the airflow so as to avoid environmental pollution caused by exhausting the cooking fume outside, can be used in the place at which an external air exhausting duct cannot be mounted, and can effectively prevent the cooking fume of the hearth from diffusing towards the space out of the hearth, leading to more sanitary working environment.

Description

technical field [0001] The invention relates to a cooker for kitchen, in particular to a cooker which filters the air flow carrying oil fume and then circulates it. Background technique [0002] At present, the cooker with the oil fume suction device used in the prior art usually discharges the sucked air flow with oil fume directly into the external atmosphere through the pipeline or discharges the air flow into the external atmosphere after simple oil fume filtering; The disadvantage is that even if the simply filtered fume flow is directly discharged into the external atmosphere, it will still pollute the external atmosphere. At the same time, this device cannot be used in environments such as restaurants where external exhaust pipes cannot be installed. Contents of the invention [0003] The present invention aims to overcome the above-mentioned defects in the prior art, by setting a device for preliminary oil fume filtration and wet filtration on the suction cooktop t...
