Exhaust structure, cooking device with exhaust structure, and exhaust method of cooking device

Abstract

The invention relates to an exhaust structure. The exhaust structure comprises an inner container and an upper mounting plate positioned above the inner container; an exhaust hole is formed in the topwall of the inner container; the exhaust structure is characterized by further comprising an exhaust system with a fan and an exhaust cavity; an air inlet of the exhaust cavity is in fluid communication with the exhaust hole; the exhaust system comprises an exhaust channel communicating with the outside and a fan cavity used for installing the fan; the fan is provided with an upper impeller and alower impeller which are arranged in an up-down manner; the fan cavity is provided with an upper air inlet and a lower air inlet corresponding to the upper impeller and the lower impeller respectively; the lower air inlet of the fan cavity is in fluid communication with an air outlet of the exhaust cavity; and an air outlet of the fan cavity is in fluid communication with an air inlet of the exhaust channel. The invention further relates to a cooking device with the exhaust structure and an exhaust method of the cooking device. The exhaust efficiency of the cooking device can be improved; steam in the inner container can be prevented from being directly sprayed to a user after steaming; and the usage experience of the user is improved.

Description

technical field [0001] The invention relates to the field of steaming and cooking devices, in particular to an exhaust structure, a cooking device with the structure and an exhaust method thereof. Background technique [0002] The top of the liner of the integrated steaming and roasting machine is generally provided with an exhaust port, and the exhaust port is provided with an exhaust pipe, and the exhaust pipe communicates with the exhaust channel with the exhaust fan. When the exhaust blower rotates like this, the gas of inner bag enters in the exhaust channel by exhaust pipe, is discharged outward by exhaust channel. In the steaming mode, after the steaming is finished, a large amount of steam will remain in the inner tank. At this time, when the user opens the door, the steam in the inner tank will directly spray the user, thereby reducing the user's experience. [0003] The size of the exhaust port of the existing integrated steaming and roasting machine is fixed, whi...

AI Technical Summary

Problems solved by technology

[0003] The size of the exhaust port of the existing all-in-one steaming and roasting machine is fixed, which will make the baking uniformity poor, and the water vapor near the exhaust port evaporates faster, and the food is easily burnt, which affects the baking effect

Moreover, if the size of the exhaust port is small, the steam will not be discharged smoothly during steaming, which will cause whistling sound, and if the size of the exhaust port is large, the effect of steaming will be affected
