Description
Technical Field
The utility model relates to an oven specifically is a take high-efficient thermal-insulated and heat radiation structure's electric oven.
Background
In recent years, the related technical trade measures for barbecue appliance products are becoming stricter in eu countries. In 2007, the A12 supplement of EN60335-2-9 standard exported by the European Union once influences related export products to a certain extent, and the European Committee for standardization of electrotechnics (CENELEC) formally releases the A13 supplement of EN60335-2-9 standard of household baking type electric appliances in 11 months in 2010. The supplement was started in the eu member countries from 2011 at 10/1 and was enforced from 2013 at 10/1. The A13 supplement greatly changes the requirement of temperature rise test of the barbecue appliance product and greatly increases the requirement of temperature rise limit value of the test component. If the metal surface of the coating is reduced to 55K from the original 85K (K refers to the temperature of each part in the electronic and electrical equipment higher than the environment), and the glass surface is reduced to 60K from the original 95K, the updating of the industrial standard puts higher and more rigorous requirements on the design and development of products, and a plurality of electric oven products in the current market cannot meet the new standard, so that enterprises are rejected from the market of European Union, and finally the market of European Union is abandoned passively.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the shortcomings of the prior art, providing an electric oven with high-efficiency heat insulation and heat dissipation structure, which has simple structure, convenient production and processing and low production cost and can meet the European Union A13 standard.
The utility model discloses the purpose is realized with following mode: an electric oven with a high-efficiency heat insulation and dissipation structure comprises an outer shell and an inner container, wherein openings are formed in the front ends of the outer shell and the inner container, a box door covers the openings, the inner container is hollow to form a baking area, and an electric heating tube and a baking net are arranged in the baking area.
The supporting legs are arranged by protruding the upper surface or the lower surface of the plate body material downwards or upwards, and the supporting legs between two adjacent heat insulation plates are arranged oppositely.
The supporting legs are arranged in a circular truncated cone shape in a protruding mode.
The back plate of the shell is also provided with heat dissipation holes.
The heat dissipation holes are transversely arranged in a long strip shape.
And shutter type heat dissipation windows are arranged on two sides of the shell.
The utility model has the advantages that: 1. simple structure, low production cost and improved market competitiveness. 2. In the scheme, the upper end of the inner container of the oven is provided with a plurality of layers of heat-insulating sheets, and the convection area is isolated between two adjacent heat-insulating sheets through the supporting legs, so that the heat-insulating sheets block the heat in the electric oven from being conducted to the outside, the surface temperature of the electric oven is effectively reduced, and the requirement of the temperature rise limit value of an supplement part of a domestic baking electric appliance EN60335-2-9 standard A13 which is exported from the European Union is met.

Detailed Description
The present invention will be further described with reference to the accompanying drawings. An electric oven with a high-efficiency heat insulation and dissipation structure comprises an outer shell 1 and an inner container 2, wherein openings are formed in the front ends of the outer shell 1 and the inner container 2, a door 3 is covered on the openings, a baking area 4 is formed in the inner container 2 in a hollow mode, and an electric heating tube 5 and a baking net 6 are arranged in the baking area 4.
The supporting legs 11 are arranged by protruding the upper surface or the lower surface of the plate body material downwards or upwards, and the supporting legs 11 between two adjacent heat insulation plates are arranged oppositely.
The supporting legs 11 are arranged in a circular truncated cone shape in a protruding mode.
The back plate of the shell 1 is also provided with heat dissipation holes 13.
The heat dissipation holes 13 are transversely arranged in a long strip shape.
And shutter type heat dissipation windows 15 are arranged on two sides of the shell 1.
The working principle is as follows: according to the scheme, the first heat insulation plate, the second heat insulation plate and the third heat insulation plate are arranged on the top of the inner container in a stacked mode, the two adjacent heat insulation plates are separated through the supporting legs to form a convection area, heat radiation and convection can be effectively reduced, heat conduction is effectively blocked, and the surface temperature of the shell is effectively reduced, so that the temperature rise limit requirement of a supplement piece of a domestic baking type electric appliance EN60335-2-9 standard A13 of the European Union is met.
