Structure for covering door of electric oven

Abstract

A shielding structure for the gate of electric oven is composed of a front panel before the cavity of electric oven, a gate on said front panel and consisting of gate frame and glass plate in the gate frame, a heat shielding part on said front panel and in contact with said glass plate when the gate is closed for isolating heat and preventing the leakage of electromagnetic waves, and an electromagnetic shielding part on said glass plate.

Description

technical field [0001] The invention belongs to an electric oven device of microwave ovens, and in particular relates to an electric oven door covering structure that more completely cuts off electromagnetic waves and internal heat leaking to the outside in a pull-down door type. Background technique [0002] Generally, an electric oven is a machine for heating and cooking food with electromagnetic waves as a heating source. Recently, an electric oven with a heater is housed as another heating source for strengthening electromagnetic wave heating. In an electric oven with a built-in heater, the temperature inside the cavity rises above 450°C, so a covering structure is formed around the door to prevent electromagnetic waves from leaking to the outside and to cut off heat transfer to the outside. Such as figure 1 , 2 As shown, the electric oven includes a closable door 7 located on the front panel 5 in front of the shell forming the oven chamber 1 , and a covering structure...

Problems solved by technology

However, in the previous electric oven door covering structure as described above, in order to prevent electromagnetic waves from leaking through the gap generated by the heat covering parts, such as figure 2 Shown is provided with the blocking portion 17 that protrudes to the inside of furnace cavity, as image 3 As shown, the cover grooves 9a, 9b are formed on the door frame 9', but there is no structure for cutting off electromagnetic waves on the heat shielding parts 15, 15', so it is difficult to ensure that the electromagnetic waves are cut off, and the reliability is not high.

[0004] In addition, in image 3 The medium heat shielding member 15' is provided on the outer side between the door frame 9' and the front panel 5', so the glass fixing member 19 supporting the heat-strengthened glass 11' on its inner part can only be made of metal materials in terms of heat resistance. , which limits the scope of design material selection and increases manufacturing costs
