Heat insulation cover of kitchen range

Abstract

The invention discloses a h at insulation cover of a kitchen range. The heat insulation cover comprises a heat insulation cover body, and the heat insulation cover body sleeves a combustor, and the bottom of the heat insulation cover body is detachably connected to a surface plate. The heat insulation cover body comprises a first channel and a second channel, the first channel leads to the outer side of an outer fire cover through a clearance between the heat insulation cover body and the outer fire cover, and the second channel leads to the clearance between the outer fire cover and an innerfire cover through a combustion channel. The second channel flows to the outer side of the outer fire cover and the outer side of the inner fire cover separately, so that more secondary air is provided for combustion of the inner fire cover and the outer fire cover, and then the combustion efficiency of the combustor is improved.

Description

technical field [0001] The invention relates to a cooker heat shield. Background technique [0002] At present, many cookers on the market use a double-layer heat shield to increase the efficiency of the cooker. The heat shield is composed of two layers, the inner and the outer. There are two connections between the two layers. The inner layer is close to the flame area and has a higher temperature. The inner layer quickly conducts to the outer layer through the contact parts, resulting in a very high temperature on the outer layer. Since the bottom of the outer layer of the heat shield is connected to the first panel, part of the heat in the outer layer of the heat shield is transferred to the first panel through heat transfer, causing the temperature rise of the first panel to be too high, posing a safety hazard; in addition , the outer layer of the heat shield is exposed to the air and is affected by the surrounding convection, resulting in the heat transfer from the out...

Since the bottom of the outer layer of the heat shield is connected to the first panel, part of the heat in the outer layer of the heat shield is transferred to the first panel through heat transfer, causing the temperature rise of the first panel to be too high, posing a safety hazard; in addition , the outer layer of the heat shield is exposed to the air and is affected by the surrounding convection, resulting in the heat transfer from the outer layer of the heat shield to the air through heat conduction and convection

[0003] Since the heat shield dissipates heat through the above two forms, the temperature of the outer la
