Abstract

The invention relates to a dual-purpose electric cooker heating device. The heating device comprises a heating disc, a tubular electric heating element circle is arranged on the inner wall face of the heating disc, two heating pieces are additionally arranged in the center of the heating disc, namely, and the two heating pieces are the 12 V constant-temperature heating piece I and the 12 V constant-temperature heating piece II. A circuit where the constant-temperature heating piece I is located is provided with a contact switch, and a magnetic steel temperature limiter is connected into the circuit in series. The dual-purpose electric cooker heating device has the advantages that two 12 V PTC heating pieces are arranged in the heating disc, two kinds of currents are adopted, namely, the 220 V current and the 120 V current can be used for cooking, and in combination with the daily 220 V tubular electric heating element, the effect of independent heating can be achieved through the independent current; when the 220 V current is set outside the heating disc, people can cook only by plugging a 12 V power source.

Description

A kind of dual-purpose electric cooker electro-heat equipment

Technical field

The present invention relates to electric rice cooker heated technology, relate in particular to a kind of dual-purpose electric cooker electro-heat equipment.

Background technology

Electric cooker is a kind of modernization cooker that the multiple processing such as can steam, boil, stew, simmer, boil in a covered pot over a slow fire.It not only can cook food ripe, and can be incubated, and uses sanitation and hygiene, does not pollute, time saving and energy saving, is one of indispensable apparatus of housework modernization; Its operating temperature is mostly upper and lower at 100 ℃.The temperature control component of electric cooker has bimetal leaf temperature control system and magnetic material temperature control system, electric cooker is divided into combined type and monoblock type by the version of pot body, during by use, pot inner pressure is divided into low pressure, middle pressure type and high voltage type, by the mode of heat food, is divided into direct-heating type and indirect heating type.

The heating adopting is generally metal pipe type, mostly casts from aluminium matter heating board, and the heat sending heats inner pan body bottom equably through heating board.General electric cooker is only established a bottom electrical thermal element, for obtaining the better effect of cooking, establishes 2～4 heatings on some expensive goods, and as capping heater, all heaters of side, power can divide many grades respectively.

The electric cooker using at present, all to adopt liner and heat-generating disc Split type structure, the effect of liner is mainly used for an electric component for fixing heat-generating disc, decoration, heat insulation and protection pot body the inside, heat-generating disc generally adopts cast aluminium heat-generating disc, be fixed on above the bottom of liner, the major defect operation of this structure is many, complex process, consumptive material is many and during installation fee; Meanwhile, the cast aluminium heat-generating disc adopting, there is the problems such as heat transfer is inhomogeneous, heat transfer efficiency is low in heat-generating pipe wherein.

These are all the basic summaries to existing electric rice cooker heated structure above, and this case institute emphasis is pointed out that, existing electric cooker only separately a 220V electric current cook or have a kind of truncate electric cooker 12V, but can only be incubated.Therefore,, for above aspect, need to effectively innovate prior art.

Summary of the invention

For above defect, the invention provides and a kind ofly adopt that two kinds of electric current 220V, 12V can cook, independent heating, dual-purpose electric cooker electro-heat equipment easy to use, to solve many deficiencies of prior art.

For achieving the above object, the present invention is by the following technical solutions:

A dual-purpose electric cooker electro-heat equipment, comprises heating disk body, on described heating disk body internal face, a circle tubular electrothermal element is set, and sets up two fever tablets, i.e. 12V constant temp. warming sheet I, 12V constant temp. warming sheet II at heating disk body center position;

The circuit band contact switch at described constant temp. warming sheet I place and series connection access magnetic steel temperature limiter, contact switch parallel connection outside access insulation indicator lamp wherein, indicator lamp of cooking of constant temp. warming sheet I parallel connection outside;

The circuit band contact switch at described constant temp. warming sheet II place, contact switch parallel connection outside access insulation indicator lamp, a branch road being connect by second contact switch and insulation temperature detect switch (TDS) group in parallel on insulation indicator lamp branch road.

The circuit series connection access magnetic steel temperature limiter at described constant temp. warming sheet II place; Indicator lamp of cooking of described constant temp. warming sheet II parallel connection outside.

The beneficial effect of dual-purpose electric cooker electro-heat equipment of the present invention is: when only having in the environment of 220V power supply, can adopt separately tubular electrothermal element to generate heat and cook; In the environment at 12V power supply, the PTC fever tablet that employing arranges two 12V in disk body in heating is generated heat and is cooked, can adopt separately wherein a kind of electric current, be that 220V or 12V power supply all can be cooked, because electric cooker arranges the power interface that is designed with respectively 220V and 12V, when not having in the environment of 220V power supply, only need plug the power supply of 12V and just can cook.

Accompanying drawing explanation

With reference to the accompanying drawings the present invention is described in further detail below.
