Abstract

A multifunctional electric cooker, which comprises an upper cover plate, a lower cover plate, a heating unit, support legs and a washer, wherein the application of a ceramic washer realizes complete inosculation of the interface between the heating unit and the electric cooker to reduce loss of heat, thus the ceramic washer is capable of both heating and insulation functions; or a temperature limiter can be added to limit the temperature. The utility model is characterized by: rational design, simple structure, convenient installation, small size, light weight, material saving, easy manufacturing and low cost, thus is fit for popularization.

Description

The multifunctional electric cooker heat-generating disc

Technical field

The utility model belongs to the electro-heat equipment of kitchen utensils, particularly a kind of multifunctional electric cooker heating board.

Background technology

At present, the electro-heat equipment of kitchen utensils such as the heat-generating disc of electric cooker, when running into 600-800 ℃, its surface can be out of shape to some extent, and misfit the R position in the electric cooker between the heat-generating disc of pot, the coefficient of overall heat transmission is reduced, thereby influence the quality of electric cooker, and promptly be that traditional heater and heating container contact-making surface are inconsistent and loss heat energy causes the waste of energy, be not inconsistent energy-conservation requirement.

Summary of the invention

The purpose of this utility model provides a kind of multifunctional electric cooker heat-generating disc, utilizes ceramic washer that heater and electric cooker contact-making surface are fitted like a glove, and reduces the loss of heat energy, and heating and heat insulating functions are arranged, or install temperature limiter additional, and reaching the purpose of limit temperature, should promote the use of.

The utility model is made up of loam cake, lower cover, heater, leg, packing ring, between loam cake (1) and lower cover (2), heater (3) is housed, between heater (3) and lower cover (2) projection, 3 packing rings (4) are housed, at loam cake (1) through hole (6) is arranged, go up uniform 3 legs (5) at lower cover (2).

The utility model is reasonable in design, and is simple in structure, easy for installation, and volume is little, in light weight, saves material, makes easily, and cost is low, should promote the use of.

The specific embodiment

As shown in Figure 1, 2, available steel of loam cake of the present utility model (1) or aluminium drawing and forming, there is through hole (6) centre.Heater (3) be on the heatproof mica sheet around nickel-chromium resistance wire, lower cover (2) is used the steel punch forming, leg (5) is made with bakelite or steel plate, packing ring (4) is made with pottery, presses shown in Fig. 1,2 assembling then and just can.

Shown in Fig. 3,4, the utility model can reach the function of limit temperature if in the through hole (6) of loam cake (1) temperature limiter (7) is housed.

As Fig. 5, shown in 6, heater of the present utility model (3) is made up of heatproof mica sheet (8) and 3 blocks of heatproof mica sheets (9), 2 blocks of heatproof mica sheets (9) are arranged on the heatproof mica sheet (8), there is 1 block of heatproof mica sheet (9) to stack below, heatproof mica sheet (9) punch forming rear perimeter edge is evenly equipped with 50-80 tooth, tooth depth is 0.3-0.5mm, be wound with nichrome wire (10) at tooth root, heating wire (10) can be circle or flat, insulation sheet (11) is housed on every block of heatproof mica sheet (9), and insulation sheet (11) is to be wound with nichrome wire (12) in two heel teeth mouths of fan-shaped mica sheet.

The various functions of the utility model collection tradition electric heater are got Qi Gechang.Be that the various advantages of polymerization tradition electric heater are one, its volume is little, in light weight, the novel heating board that the thermal efficiency is high, function with heating and insulation, limit temperature, function with unidirectional thermal-radiating efficient heating, it is inconsistent and loss heat energy causes the waste of energy to have solved traditional heater and heating container contact-making surface, and than traditional heat-generating disc economize on electricity 30%, firing rate is fast, during than the electric cooker of traditional heat-generating disc joint 30%.
