Background technology
The design of the heat-proof device of traditional electric cooking appliance (comprising electric oven, micro-wave oven) is all that the left side plate of thermal insulation board and cavity is locked together.Or the top board of thermal insulation board and cavity is locked together.Chinese patent literature CN2779879 discloses a kind of electric oven on May 17th, 2006, comprise the electric oven body, the electric oven side, between the Shell Plate of the right plate of internal cavity of electric oven and electric oven, be provided with control panel, be provided with thermal insulation board between right plate and Shell Plate, form a heat insulation cavity between right plate, back side panel and thermal insulation board, sensor setting is in heat insulation cavity.It is said, it forms a heat insulation cavity by between the right plate at internal cavity of electric oven and Shell Plate, being provided with thermal insulation board between right plate, back side panel and thermal insulation board, cut off heat and the electrical equipment cavity direct heat transfer of internal cavity of electric oven, reduces the temperature of electrical equipment cavity; But this design is just undertaken heat insulation by the reflection of thermal insulation board, do not form runner, does not have the effect of heat radiation, so effect of heat insulation is not good.Therefore, be necessary to be further improved.
The utility model content
The purpose of this utility model aims to provide a kind of simple and reasonable, heat insulation and dissipation device of assembling the electric cooking appliance convenient, that cost of manufacture is low, to overcome weak point of the prior art.
The heat insulation and dissipation device of a kind of electric cooking appliance designed by this purpose, comprise cooker main body, thermal insulation board, header board and rear wall plate and outer cover, wherein header board and rear wall plate are assemblied in respectively front side and the rear side of cooker main body, the top of cooker main body is a top board, and its architectural feature is that thermal insulation board connects the top that is arranged between header board and rear wall plate, is positioned at top board.
The top, front side that is arranged at the cooker main body is extended on the top of described header board, and the top of header board has one and attaches together the installing hole of joining with the control panel assembly.
The downside of the corresponding installing hole in the top of described header board bending forming backward has a horizontal flange, and an end of thermal insulation board is fixed on flange, and the other end is fixed on rear wall plate.
Between described cooker main body and header board, rear wall plate and outer cover, assembling surrounds a heat insulation cavity volume, and heat insulation cavity volume is divided into upper and lower two opening runners by thermal insulation board.
The corresponding heat insulation cavity volume in the surface of described rear wall plate is provided with several louvres, and the corresponding heat insulation cavity volume in the surface of outer cover is provided with several shutters.
The utility model, by thermal insulation board is connected to locking with header board with rear header board, forms two opening runners simultaneously; By the shutter of outer cover surface convection current and the louvre of back drywall surface, heat is dissipated, improve the surface temperature rise of baking box and micro-wave oven, play the double effects of heat insulation and dissipation; In addition, this device connects header board and rear wall plate by thermal insulation board, has greatly strengthened the intensity of header board and rear wall plate, and there is to great role in the gap of improving outer cover and control panel.It can overcome the problem of electric cooking appliance (comprising baking box and micro-wave oven) surface temperature rise, and particularly the problem for the A12/A13 of European Union has important effect.
