Description
Technical Field
The utility model relates to a radiation heat cooking utensils field specifically relates to an electric stove plate of compact structure.
Background
The domestic radiant-heating electric cooker originated from 1904 years, and the electric cooker is used as a heat source of the electric cooker by electrifying and heating through a resistance wire. Over a hundred years, the electric stove is greatly changed along with the development of material technology and control technology, but the heat conversion efficiency of the radiant heat stove in the latest technology is always limited to be about 70 percent due to the heat conversion characteristics and stove structure characteristics of the radiant heat stove; the manner of heat transfer has not always changed the weak point of slow thermal response.
The electric cooker disclosed in patent document CN203349318U comprises a shell with an upper opening, a panel, a heat insulation and heat collection disc with an upper opening, a nickel-chromium metal heating body, a fan and a control device, wherein the shell comprises a shell body made of metal material and provided with an upper opening and a lower opening, a bottom cover plate made of metal material, a base made of plastic material and provided with an upper opening, a guide rod and a pressure spring, an angular connecting seat is arranged on the heat insulation and heat collection disc, the connecting seat comprises a vertical plate and a horizontal plate, the vertical plate is fixedly connected with the heat insulation and heat collection disc, and a guide hole is arranged on the horizontal plate; the circuit board is embedded into the base, the lower end of the guide rod is fixedly connected with the bottom cover plate of the shell, and the upper end of the guide rod penetrates through the pressure spring and is in sliding fit with the guide hole of the horizontal plate.
Despite the rapid development of materials and control technology over the years, the energy efficiency improvement of heat radiation furnaces is limited by the bottleneck of slow temperature response. The reason for this is (see fig. 1):
the existing technology of a heat radiation oven plate is that an arc-shaped alloy resistance wire sheet is attached to an upper plate of a heat insulation oven plate formed by nanometer powder, the resistance sheet is electrified to generate heat, a microcrystalline glass ceramic plate is heated through conduction, radiation and convection, and then the microcrystalline glass ceramic plate conducts the heat to the bottom of a cooking pot. According to the safety standard requirement of an electric cooker, a heating wire (charged body) needs to be enhanced in insulation, although a microcrystalline glass ceramic plate of the cooker is an insulator at normal temperature, the microcrystalline glass ceramic plate is used for a cooking panel of a radiant heating furnace, the temperature of the microcrystalline glass ceramic plate can reach 600 ℃ when the cooker works, the insulation characteristic of the microcrystalline glass ceramic plate is rapidly reduced, and therefore, from the insulation safety of the cooker, the heating wire needs to be spaced from the microcrystalline glass ceramic plate by a certain distance (space 15mm distance) so as to meet the insulation requirement. Therefore, with current technology and materials used, the heater is not allowed to be directly attached to the glass ceramic plate.
Because the heating wire is 15mm away from the microcrystalline glass ceramic plate, the medium between the heating wire and the microcrystalline glass ceramic plate is air, and the heat conductivity coefficient of the dry air is 0.023W/m.k under a closed state, the ceramic plate belongs to a medium (heat insulation material) with poor heat conductivity. This special structure of the radiant heat furnace inevitably leads to the inevitable result of slow temperature change (large time constant) and low thermal conversion efficiency of the radiant heat furnace.
