Abstract

The utility model discloses a heating plate. The heating plate body is formed by a metal casing and a metal sub cover, the heating plate body is internally equipped with a heat-transfer metal and a heating device and is stuffed with heat-transfer materials. A pressure foot and at least three striking flake pressure-relief abutments are arranged at the bottom of the heating plate, wherein the striking flake pressure-relief abutment is equipped with a screw in the centre, the heating plate is connected with a pan casing through fastening screws. When the pressure of the pan is increased because of heating, the heating plate sinks and extrudes downwards, and the striking flake pressure-relief abutment is deformed, and the temperature-control circuit is cut off or to heating power is adjusted and reduced by the pressure foot actuates inching switch (pressure switch). The heating plate of the utility model has the advantages that the product structure is simplified, the manufacture cost is reduced, the service life of the heating plate is prolonged because striking flake pressure-relief abutment can be changed conveniently, and can be widely applicable to electrical appliances with heating components at the bottom, such as an electric pressure cooking saucepan, an electric chafing dish, an electric steamer, an electro thermal saucepan, an electric cooker, and an electric kettle or the like.

Description

A kind of heat-generating disc

Technical field

The utility model relates to home cooking apparatus technical field, especially a kind of heater.

Background technology

Electric pressure cooker is a mess kit common in the family, and its environmental protection and energy saving easy to use is more and more accepted for people and liked.Electric pressure cooker normally changes by the perception domestic pressure, realizes the control to the state of power supply.Electric pressure cooker of the prior art is all installed elastic supporting mechanism on heat-generating disc, change with perception pot body pressurized.The heat-generating disc elastic mechanism, mainly adopt and establish compression spring, helical spring between heat-generating disc and outer mistake, the dish type elastic device makes behind the heat-generating disc pressurized outer pot generation micro-displacement relatively, thereby touch switch and control heating power is to reach the purpose of control pot inner pressure.As application number is 9724005, and name is called a kind of pressure adjustable electric pressure cooker, and realize by the spirality support spring by being provided with for its pressure relief device, and it is characterized in that: A is evenly distributed with some identical spirality support springs between heat-generating disc and outer pot; B, be provided with drive link between outer pot and the shell, one end of drive link connects reset button, the other end is fixed with pushing piece and driving convex position, be provided with a drive rod directly over the driving convex position, drive the upper end of doing and be fixed on the heat-generating disc bottom, drive rod and driving convex position are with a switch spring outward, the middle part is done in transmission has the articulated mounting that is fixed on the outer pot bottom surface hinged, a side in the enclosure is provided with adjusting slider, the upper end of adjusting slider is connected to by a cam and regulates the preface knob, and the lower end of adjusting slider is friendship magnet fixedly, and magnet is positioned at the below of reset button one end of drive link.This supporting mechanism adopts the spirality support spring exactly, by displacement switch control inner pot pressure, but this product structure complexity, the production cost height.

The utility model content

The purpose of this utility model provides a kind of heat-generating disc, and heat-generating disc comprises pressure relief device, and it is simple in structure, is easy to change, and reduces production costs.

The utility model is realized above-mentioned purpose by following technical proposal: a kind of heat-generating disc, metal housing and metal bottom cover surround the heat-generating disc main body, the heat-generating disc center is provided with through hole, the heat-generating disc body interior is provided with heat-transfer metal sheet and electro-heat equipment and fills heat-transfer matcrial, the heat-generating disc bottom is provided with pressure foot, the heat-generating disc bottom is provided with at least three shell fragment release bearings, and shell fragment release bearing center is provided with screw and by trip bolt heat-generating disc and the external cover of pot is coupled together.

Further, described shell fragment release bearing is made of at least three thin slice legs, is symmetrical petal-shaped and launches, and leg outwards is form of hooks.

Further, described shell fragment release bearing center bends depression downwards, is provided with screw in the depression.

The utility model heat-generating disc has been simplified product structure, has reduced production cost, and shell fragment release bearing can change easily, thereby prolongs the useful life of heat-generating disc.The utility model can be widely used in bottom heating electrical appliance parts such as electric pressure cooker, electric chafing dish, electric steamer, electrothermal furnace, electric rice cooker and electric kettle.

Embodiment

Below in conjunction with Fig. 1, Fig. 2 is described in detail the utility model: a kind of heat-generating disc, metal housing 1 and metal bottom cover 10 surround the heat-generating disc main body, attemperating unit is arranged in the heat-generating disc central through hole 3, the heat-generating disc body interior is provided with heat-transfer metal sheet 2 and electro-heat equipment 5 and fills heat-transfer matcrial 4, the heat-generating disc bottom is provided with pressure foot 6, the heat-generating disc bottom is provided with at least three shell fragment release bearings 8, every bearing 8 has at least two thin slice legs 82 and formation, being symmetrical petal-shaped launches, the leg 82 outwardly-bent form of hooks that are, described shell fragment release bearing 8 centers bending recess is provided with screw 81 and by trip bolt 9 heat-generating disc and the external cover of pot is coupled together.In the time of in the heat-generating disc heating pot, interior pot is because internal pressure reaches setup pressure value and moves down, heat-generating disc is sunk to be pushed downwards, shell fragment release bearing generation elastic deformation, the pressure foot that is arranged on the heat-generating disc bottom touches sensitive switch (pressure switch), temperature control circuit is opened circuit or regulate the reduction heating power, thereby realize the purpose of control heat-generating disc work.

Be provided with thermal insulation layer between heat-generating disc internal heat transfer material 4 and the metal bottom cover 10, filling with insulation material 7 effectively deadens heat and scatters and disappears from the bottom, thereby improves heating efficiency.There is anti-skidding striped on heat-generating disc metal housing 1 surface, and anti-skidding striped not only has antiskid function, and increases heat transfer area, effectively improves the heat-generating disc heat transfer efficiency.

The utility model heat-generating disc, simplified product structure, improve heating properties, effectively reduce production cost simultaneously, and shell fragment release bearing can be changed easily, thereby prolong the useful life of heat-generating disc, the utility model can be widely used in bottom heating electrical appliance parts such as electric pressure cooker, electric chafing dish, electric steamer, electrothermal furnace, electric rice cooker and electric kettle.
