Abstract

The utility model discloses a kind of electric cooker with bimetallic temperature controller protection circuit; include electric cooker body and the heating and thermal insulation circuit positioned at electric cooker body interior; the heating and thermal insulation circuit includes the heating module circuit and heat preservation module circuit of concatenation; one connection end of heating module circuit connects zero line circuit by protector; the series side of heating module circuit and heat preservation module circuit is connected with key switch, and the other end line of key switch and heat preservation module simultaneously connects live wire circuit after connecing by bimetallic temperature controller.The utility model installs anti-dry bimetallic temperature controller additional in heating and thermal insulation circuit; circuit structure is simple; cost is low; utilize the power-off of bimetallic temperature controller high temperature, the automatically reset architectural characteristic of low temperature; bimetallic temperature controller can be disconnected automatically when electric cooker constant temperature is too high in use, and so as to cut off circuit, bimetallic temperature controller and can automatically resets after constant temperature reduces; circuit is reclosed, plays safeguard protection effect.

Description

A kind of electric cooker with bimetallic temperature controller protection circuit
Technical field
A kind of electric cooker is the utility model is related to, belongs to machine for kitchen use product technical field, is referred in particular to a kind of with double The electric cooker of metal temperature control device protection circuit.
Background technology
In the heating and thermal insulation circuit of existing electric cooker, magnetic control elastic sheet switch and warmer etc. are substantially to be connect by shell fragment elastic force Touching what is be powered, shell fragment elastic force increases with access times, can gradually weaken under the high temperature conditions, on the other hand, switch contact Resistance for a long time in the environment such as kitchen humidity, oil smoke using also gradually increasing, such high current by when easily generate heat, a hair Thermoelastic piece elastic force reduces again, causes loose contact, and loose contact resistance increases again, causes magnetic switch and warmer to be operated in one In individual high temperature vicious circle, following danger, such as magnetic control elastic sheet switch are easily caused easily to be failed, resistance is excessive, and high current is led to Cross heating easy burn-out and burn heating disk of electric rice pot and inside and outside portion's electric power connection line etc., not only cause damage to property, and peace be present Full hidden danger.
Utility model content
The purpose of this utility model is to overcome shortcoming and deficiency of the prior art, there is provided one kind has bimetallic temperature control The electric cooker of device protection circuit, the heating and thermal insulation circuit of the electric cooker have anti-dry bimetallic temperature controller, when electric cooker generates heat When the constant temperature of disk heating is too high, bimetallic temperature controller meeting automatic shutdown circuit, safeguard protection effect is played, treats bimetallic temperature Control device Wen Duxiajiang after, electric cooker again can turn on automatically power supply work on.
To achieve these goals, the utility model is realized according to following technical scheme:
A kind of electric cooker with bimetallic temperature controller protection circuit, includes electric cooker body and positioned at electric cooker body Internal heating and thermal insulation circuit, the heating and thermal insulation circuit include the heating module circuit and heat preservation module circuit of concatenation, added One connection end of thermal modules circuit connects the series side of zero line circuit, heating module circuit and heat preservation module circuit by protector It is connected with key switch, the other end line of key switch and heat preservation module simultaneously connects live wire line after connecing by bimetallic temperature controller Road.
Further, the bimetallic temperature controller uses rectangle Automatic-reset resilient structures, has two soft metal electricity Draw line in source.
Further, the bimetallic temperature controller is fixed on the bottom inner chamber of electric cooker body by clip, in electric cooker The heating dish in internal portion disengages.
Compared with prior art, its advantage is the utility model:
The utility model installs anti-dry bimetallic temperature controller additional in heating and thermal insulation circuit, and circuit structure is simple, and cost is low, Using the power-off of bimetallic temperature controller high temperature, the automatically reset architectural characteristic of low temperature, in use when electric cooker constant temperature Bimetallic temperature controller can be disconnected when too high automatically, so as to cut off circuit, after constant temperature reduces bimetallic temperature controller and can from It is dynamic to reset, circuit is reclosed, plays safeguard protection effect.
In order to be able to apparent understanding the utility model, illustrated below with reference to brief description of the drawings of the present utility model specific real Apply mode.
Brief description of the drawings
Fig. 1 is the real electrical block diagram of the utility model.
Fig. 2 is inner-cavity structure schematic diagram in bottom of the present utility model.
Remarks:Respectively cooked indicator lamp, D2 insulation indicator lamps, R3 and R4 marked as R1 heat-generating discs, R2 insulation sheets, D1 in Fig. 1 Dropping resistor, AN key switches, T bimetallic temperature controllers, RD protectors.
Embodiment
As shown in Figure 1, 2, the electric cooker described in the utility model with bimetallic temperature controller protection circuit, includes electric meal Pot body and the heating and thermal insulation circuit positioned at electric cooker body interior.
Above-mentioned heating and thermal insulation circuit includes the heating module circuit and heat preservation module circuit of concatenation, heating module circuit One connection end connects zero line circuit by protector, and the series side of heating module circuit and heat preservation module circuit is connected with button and opened Close, the other end line of key switch and heat preservation module simultaneously connects live wire circuit after connecing by bimetallic temperature controller.
Further, the bimetallic temperature controller is fixed on the bottom inner chamber of electric cooker body by clip, in electric cooker The heating dish in internal portion disengages, and it uses rectangle Automatic-reset resilient structures, and there are two soft metal power supplys to draw Line.
Protection circuit of the present utility model uses bimetallic temperature controller, has the function of automatic switching electricity, when electric cooker Heating-up temperature can automatically power off when exceeding safe temperature, reach the purpose of anti-dry, treat the temperature automatic descending of overheating of electric rice cooker To after design safety temperature value, electric cooker is the electrified regulation that automatically resets, and being not required to artificial reset can just work.
The utility model is not limited to above-mentioned embodiment, if various changes or modifications to the utility model do not take off From spirit and scope of the present utility model, if these changes and modification belong to the claims and equivalents of the utility model Within the scope of, then the utility model is also intended to comprising these changes and modification.
