Baking oven with heat dissipation structure

Abstract

The invention relates to a baking oven with a heat dissipation structure. The heat dissipation structure comprises a heat dissipation passage communicated with the outside, a heat dissipation cavity and a fan cavity in which a heat dissipation fan is mounted; the heat dissipation fan is provided with an upper impeller and a lower impeller which are arranged up and down; the fan cavity is respectively provided with upper and lower air inlets corresponding to the upper and lower impellers; the upper air inlet of the fan cavity is communicated with an upper mounting space, and the lower air inletof the fan cavity is in fluid communication with an air outlet of the heat dissipation cavity; an air outlet of the fan cavity is in fluid communication with an air inlet of the heat dissipation passage; and an air inlet of the heat dissipation cavity is in fluid communication with an air outlet end port of a ventilation interlayer. According to the invention, active heat dissipation on a bakingoven door body can be implemented, so as to effectively avoid the potential safety hazard of scalding a user due to an excessively high temperature of the door body; and meanwhile, active heat dissipation on the electrical apparatus elements can be implemented, so as to avoid influence of excessively high temperatures of the electrical apparatus elements on performance and the service lives of theelectrical apparatus elements.

Description

technical field [0001] The invention relates to the field of ovens, in particular to an oven with a heat dissipation structure. Background technique [0002] The current oven generally heats food through the radiant heat emitted by the heating device, and the maximum temperature of the oven can reach 200-250°C. When modern kitchens are decorated, the block box is usually embedded in the cabinet or other structures. When the oven is working, it is easy to accumulate heat in the box and it is difficult to dissipate it. This will accelerate the aging speed of the oven circuit and electronic components, and shorten the service life of the oven. In addition, during the operation of the oven, the heat in the oven liner is transferred to the oven door, making the temperature of the oven door relatively high, and there is a risk of being scalded when the user opens the oven door.

Problems solved by technology

Although the heat dissipation structure in this patent can enter the hot air generated around the oven into the heat dissipation box through the introduction of the heat dissipation fan, and then force it to be discharged to the air outlet of the heat dissipation box to the front of the cabinet where the electric oven is embedded in the box body, which accelerates the heating process. The convection of the air around the box prevents a large amount of heat from accumulating in the cabinet embedded with the electric oven, but it still cannot completely solve the problem of heat dissipation of the oven circuit and electronic components and the problem of excessive temperature of the oven door
