Abstract

The utility model relates to a power saving automatic electric rice cooker which comprises a cooker body, a lining, a heating disk and a cover. The utility model is characterized in that a temperature inductor KW#-[2] is arranged at the central part of the cooker body; one end of the KW#-[2] is connected with the fuse LC through leaf spring, while the end is connected with the heating tube LR#-[2] through the leaf spring; the heating tube LR#-[2] is connected with the magnetic temperature limiter KW#-[1]; the heating tube LR#-[1] and LR#-[2] are respectively cast on the heating disk; the spring of the magnetic temperature limiter at the central part of the heating disk is longer than the common spring by one third. A thin round sheet is arranged at the cone section of the vent hole in the cover, and a small hole is excavated in the thin round sheet. The utility model has the advantages that: the structure is simple; the two heating tube are both working before the water is boiled; when the water is boiled, one heating tube automatically stops while the other is still at work, so that the power is reduced by half and the electricity is saved. The electric rice cooker is much greater in effect and saving electricity in the congee cooking and soup cooking.

Description

New type auto power saving electric cooker

Technical field:

The utility model belongs to electric cooker, especially a kind of new type auto power saving electric cooker.

Background technology:

Existing electric cooker continues heating with the boiled back of water earlier and boils up to food, because the temperature of water under normal pressure can only reach 100 ℃ when cooking.No longer heat up after water is boiled, the heat that heat-generating disc sends is most of to be taken away by a large amount of water vapours, has only small part to be used to compensate the other forms of heat that water temperature keeps boiling to be difficult to avoid and scatters and disappears, and causes energy dissipation.The pot body is made in thin rice gruel outflow simultaneously dirty.

Summary of the invention:

Technical solution of the present utility model is such, comprises by pot body, pot courage, heat-generating disc, pot cover, it is characterized in that in pot body centre position temperature inductor KW being housed ₂, KW ₂One end meets fuse LC by spring leaf, and the other end is by spring leaf sending and receiving heat pipe LR ₂, heat-generating pipe LR ₂Connect magnetic temperature limiter KW ₁, two heat-generating pipe LR ₁, LR ₂Cast on heat-generating disc heat-generating pipe LR respectively ₁One termination fuse LC, another termination magnetic temperature limiter KW ₁, the spring of the magnetic temperature limiter in the middle of the heat-generating disc adds 1/3rd than common, in the conical section of pot cover venthole a thin discs is housed, and diameter is isometric in the middle part of thin discs diameter and the conical section, and an aperture is opened at the thin discs center.The indicator lamp of cooking, heat, being incubated is installed on pot body.

The utility model has the advantages that water simple in structure, that pot is interior before not boiling, two bar heat-generating pipes are worked simultaneously, after poach is opened, are kept to the work of wall scroll heat-generating pipe automatically, and power reduces by half, and reaches purpose of power saving.This pan boiling congee, when boiling soup, better, the more power saving of effect.

Description of drawings:

Accompanying drawing is an electrical schematic diagram of the present utility model.

In the accompanying drawing, fuse LC, magnetic temperature limiter KW ₁, temperature inductor KR ₂, heat-generating pipe LR ₁～LR ₃, resistance R ₁～R ₃, indicator lamp XL cooks ₁, burner on light XL ₂, insulation indicator lamp XL ₃

The specific embodiment:

Most preferred embodiment of the present utility model is such, and shown in accompanying drawing, the pan structure of electric cooker is constant substantially, and temperature inductor KW is installed in pot body intermediate open position one hole ₂, KW ₂One end meets fuse LC by shell fragment, and the other end is by shell fragment sending and receiving heat pipe LR ₂, heat-generating pipe LR ₂Connect magnetic temperature limiter KW ₁, temperature inductor KW ₂Two shell fragments be fixed on the insulation board, the axle nail on the insulation board is fixed on the next door of heat-generating disc, the axle nail is a little more than heat-generating disc, a pot body is put into a pot courage and is depressed the axle nail and drive a temperature inductor KW ₂A contact pot courage, when in the pot courage temperature when reaching 100 ℃, temperature inductor KW ₂Automatic disconnection, heat-generating pipe LR ₂Do not work.Heat-generating pipe LR ₁One termination fuse LC, another termination magnetic temperature limiter KW ₁, two heat-generating pipe LR ₁, LR ₂Cast on heat-generating disc heat-generating pipe LR respectively ₁Adopt 350W, heat-generating pipe LR ₂Adopt 500W, the spring of the magnetic temperature limiter in the middle of the heat-generating disc adds 1/3rd than common, strengthen the spring dynamics, the disconnected temperature that rises than general electric cooker is lacked about 1 °, venthole circular cone (up big and down small) shape section at pot cover is equipped with a thin discs, thin discs diameter and conical section middle part diameter are isometric, an aperture is opened at the thin discs center, reach the heat that produces in the pot, the heat of discharging with this pore is directly proportional, and keeps the uniform temperature in the pot, and thin rice gruel does not outbound flow, pot body sanitation and hygiene, the indicator lamp of cooking, heat, being incubated is installed on pot body.

During use, two heat-generating pipe LR ₁, LR ₂Heating simultaneously, after the water in the pot courage has left, promptly pot in the courage temperature when reaching 100 ℃, temperature inductor KW ₂Automatic disconnection, heat-generating pipe LR ₂Do not work.Remaining heat-generating pipe LR ₁(350W) continuing heating boils up to food.Using electricity wisely is more than 20% like this.

Claims

A kind of new type auto power saving electric cooker comprises by pot body, pot courage, heat-generating disc, pot cover, it is characterized in that in pot body centre position temperature inductor KW being housed ₂, KW ₂One end meets fuse LC by spring leaf, and the other end is by spring leaf sending and receiving heat pipe LR ₂, heat-generating pipe LR ₂Connect magnetic temperature limiter KW ₁, two heat-generating pipe LR ₁, LR ₂Cast on heat-generating disc heat-generating pipe LR respectively ₁One termination fuse LC, another termination magnetic temperature limiter KW ₁, the spring of the magnetic temperature limiter in the middle of the heat-generating disc adds 1/3rd than common, in the venthole conical section of pot cover a thin discs is housed, and diameter is isometric in the middle part of thin discs diameter and the conical section, and an aperture is opened at the thin discs center.
