Toaster heat insulation and dissipation structure and toaster

Abstract

The invention discloses a toaster heat insulation and dissipation structure and a toaster. The toaster heat insulation and dissipation structure includes a heat insulation plate and a heating wire, and the heating wire is arranged on the heat insulation plate; and the upper part of the heat insulation plate is provided with a plurality of heat dissipation holes. The toaster includes a toaster body, and further includes the heat insulation and dissipation structure; and the heat insulation plate is arranged vertically on the inner side of the side wall of the toaster body, the heating wire is located on the inner side of the heat insulation plate, and the multiple heat dissipation holes are located in the upper part of the toaster body. According to the toaster heat insulation and dissipation structure and the toaster, by forming the multiple heat dissipation holes in the upper part of the heat insulation plate, heat trapping of the heat insulation plate is reduced, the heat dissipationeffect of the upper part of the heat insulation plate is improved, the surrounding temperature of a metal surface of the toaster, especially a roast slot window is lower than 45K, the requirement ofA13 in the (safety standard) EN60335-2-9 is met, heat insulation plate materials do not need to be additionally arranged, and thus the cost is lowered. The heat insulation and dissipation structure and the toaster have the characteristics that the structure is simple, heat trapping is reduced, and the over-temperature is prevented.

Description

technical field [0001] The invention relates to the field of small household appliances, in particular to a heat insulation and heat dissipation structure of a toaster and the toaster. Background technique [0002] <Safety standard> The test method of A13 metal surface temperature in EN60335-2-9 is: place a test point 25mm down from the window of the product oven, bake 100mm*100mm*10mm bread continuously for 3 times at the maximum power of the product, each time The interval is 10 seconds, and the highest temperature value measured when the bread is baked to a golden brown effect shall prevail, and the maximum temperature value shall not exceed 45K. [0003] In order to meet the requirements of this safety regulation, the existing toaster usually adopts the method of adding one or two layers of heat-insulating boards on the back of the heating element. Because the heat-shielding boards trap heat, the cooling effect is not obvious, and it is easy to exceed 45K, usually...

Problems solved by technology

[0003] In order to meet the requirements of this safety regulation, the existing toaster usually adopts the method of adding one or two layers of heat-insulating boards on the back of the heating element. Because the heat-shielding boards trap heat, the cooling effect is not obvious, and it is easy to exceed 45K, usually, the measured temperature of the toaster test point in the prior art is between 47.1-52.3K, and the addition of heat insulation boards also increases the cost
