Electronic oven provided with cooling system

Abstract

The invention relates to an electric oven with cooling system. It comprises a oven body, which is separated into upper and lower spaces by inner cover board, the lower space is space with high temperature to open door for high temperature zone, heater installed in inner wall and thermal insulating material installed around wall in high temperature zone; the upper space is equipped with a cooling fan, control element and control panel; the outer cover board above fan is equipped with air inlet, air channel cover board and inner cover board, all of which form into air channel; said air channel extends to top of door frame to introduce wind into the slot between inner and outer glass through upper guide board, and then the wind is discharged out from door bottom through lower guide board connected with inner glass bottom. The invention can cool control panel and control element, which guarantees life length of electric oven, and the whole surface and handle can be cooled in short time effectively for safe operation.

Description

technical field [0001] The invention relates to a device for household food processing, in particular to an electric oven with a cooling system. Background technique [0002] Electric oven is a commonly used household food processing equipment. It uses the electric heating element inside the box to grill food at high temperature. Since the internal temperature of the entire oven can be as high as 250-260°C, it may burn out electrical components during use. Affect its service life and quality, moreover, the user is also easy to be scalded accidentally. In order to prevent such possible accidents, it is conceived to design a cooling structure that can cool down the control panel and the door that opens and closes the high-temperature heating area. European Patent No.EPO330727 discloses a food oven. In this invention, the door is designed to be composed of three layers of flat glass: inner, middle and outer. Convection to achieve the purpose of natural cooling. However, cool...

AI Technical Summary

Problems solved by technology

However, cooling is inefficient as hot air escapes through the small gaps between the plates

Moreover, natural convection does not provide enough cooling effect, and the hot air discharged is directed towards the handle of the door, so the user's safety is not ideal

Also, the control panel is not well cooled

Chinese patent CN200410063728.5 discloses an "electric oven with a door cooling structure", which is similar to the above-mentioned patent door structure. Under the forced convection of the cooling fan, the air passes through the gap between the outer layer and the middle plate glass. Bottom to top, from top to bottom through the gap between the middle layer and the inner flat glass, then through the bottom, back and top of the high temperature chamber, and finally discharged from the upper end of the door, the natural air circles around the wall of the high temperature area of ​​the oven , the stroke is very long, and the contact area between the air and the high-temperature area of ​​the box is too large, resulting in a large loss of heat in the oven and a reduction in the energy consumption level of the whole machine
