Problems solved by technology

[0004] However, due to the low power density of the heating wire and the slow start-up speed, it is impossible to quickly increase the temperature of the top plate of the cavity to ensure that the temperature of the top plate is more than 5 degrees higher than the temperature of the center of the cavity, resulting in condensation water on the top plate during the heating up phase of cooking; at the same time, using aluminum foil The heating plate with heating wire structure is easy to cause uneven temperature on the top plate, and water droplets are easy to condense between the two heating wires, and the uncovered parts are also easy to condense due to low temperature

Abstract

The invention discloses a thick-film heat generation plate and an electric steam box with the same. The thick-film heat generation plate comprises a composite plate, a rare-earth thick-film dielectriclayer and a rare-earth thick-film circuit, wherein the composite plate comprises a substrate and a heat conduction layer, the heat conduction layer covers a surface of one side of the substrate, theheat conduction coefficient of the heat conduction layer is larger than the heat conduction coefficient of the substrate, the rare-earth dielectric layer is sintered on a surface of the other side ofthe substrate, and the rare-earth thick-film circuit is sintered on a surface of one side, deviating from the substrate, of the rare-earth thick-film dielectric layer and is arranged on a surface of the rare-earth thick-film dielectric layer. According to the thick-film heat generation plate disclosed by the embodiment of the invention, the composite plate comprises the substrate and the heat conduction layer, the heat conduction coefficient of the heat conduction layer is larger than the heat conduction coefficient of the substrate, so that rapid thermal starting speed, high thermal efficiency and relatively uniform heat distribution are achieved; and moreover, the rare-earth dielectric layer is arranged between the rare-earth thick-film circuit and the substrate, the insulation and heatconduction effect also can be effectively achieved, heat conduction can be ensured, and the application safety also can be improved.

Description

technical field [0001] The invention relates to the field of household appliances, more specifically, to a thick-film heating plate and an electric steamer with the same. Background technique [0002] When the electric steamer in the related art is in use, due to the cooling of the humid air in the box, the temperature drops, and the water vapor reaches saturation when the partial pressure of the water vapor is kept constant and the temperature drops to the saturation temperature corresponding to the partial pressure of the water vapor. state, when the humid air is further cooled, it will condense on the top of the box to form condensed water, and then drip on the food, affecting the taste. [0003] In some electric steamers in the related art, in order to reduce the influence of condensed water on the cooking effect, by increasing the temperature of the top plate of the electric steamer, the temperature at the top of the electric steamer is raised above the dew point temper...
