An air guiding structure and a baking and cooking device with the air guiding structure

Abstract

The invention relates to an air guide structure and a baking and cooking device thereof, comprising an exhaust passage with an exhaust fan, the exhaust passage has an air inlet, a heat preservation cover and a heat preservation cover electrically connected with the exhaust fan are arranged in the exhaust passage. A thermoelectric power generation device, the heat preservation cover is arranged on the air inlet and an air outlet connected to the air inlet is opened on the cover wall, the thermoelectric power generation device is installed on the heat preservation cover, and the heat preservation cover has a heat conducting surface, the thermoelectric power generation device The cold end of the exhaust fan is opposite to the outlet of the exhaust fan, and the hot end of the thermoelectric power generation device is in contact with the heat transfer surface. The present invention can independently generate the electricity supplied to the exhaust fan through the thermoelectric power generation device, and can self-adaptively adjust the opening and closing of the power generation function according to the amount of hot gas discharged from the inner tank. With the operation of the fan, the cold end and the hot end of the thermoelectric power generation device can always maintain a certain temperature difference, so that the stable power generation of the thermoelectric power generation device can be realized and the efficiency of power generation can be improved.

Description

technical field [0001] The invention relates to the field of grilling and cooking devices, in particular to an air guiding structure and a grilling and cooking device with the same. Background technique [0002] Cooking equipment with baking functions, such as electric ovens and integrated steaming and roasting machines, exhaust the exhaust gas generated during the baking process through the air guide structure in the working state. The existing air guide structure generally includes an exhaust fan and an exhaust channel. , the exhaust channel is formed by the wind guide cover set on the upper mounting plate and surrounded by the upper surface of the upper mounting plate, and the above-mentioned exhaust fan is generally installed on the air inlet of the exhaust channel. For example, the Chinese invention patent whose application number is CN201911042278.4 (publication number is CN110693338A) discloses an oven, which includes an inner container, a baking pan is placed horizon...

AI Technical Summary

Problems solved by technology

[0003] When the cooking equipment starts to work, the exhaust fan starts to rotate, and the motor of the exhaust fan is powered by the power board of the cooking equipment, which occupies part of the power of the power board. The startup and shutdown are only controlled by time, which is not precise enough and consumes a lot of power
