Abstract
An energy-saving heat-insulating automatic electric cooker is characterized by that a heating tube is embedded in the existent heating plate, and a heating tube is added. Two heating tubes are embedded in the heating plate; the periphery, the bottom and the cover of the electric cooker are insulated by heat-insulating materials. The load of two heating tubes or the load of one heating tube can be used according to the requirement. The power of two heating tubes in the heating plate can also be designed as follows: 2/3 and 1/3 are controlled by switches to be strong, medium and weak load gears. The energy-saving heat-preservation automatic electric cooker has the advantages of simple structure, convenient operation, safety, durability, higher thermal efficiency than that of the common electric cooker and remarkable energy-saving effect.
Description
The utility model relates to a kind of two heat-generating pipes of burying underground in the heat-generating disc of electric cooker; Around electric cooker, bottom, pot cover be with the electric cooker of insulation material insulation.Load be can reduce or increase as required, the load of a heat-generating pipe or the load of two heat-generating pipes promptly used.
At present, the main structure of known automatic electric rice cooker is: supply socket, pot body, magnetic steel temperature limiter, magnet steel temperature limit switch, heat-generating disc compositions such as (what bury underground in the heat-generating disc are a heat-generating pipe).During use, the magnet steel temperature limit switch closes, the heat-generating disc heating, magnetic steel temperature limiter is in closure state, when food in the pot boiled the evaporation minimizing, temperature of boiler raise, and the action of magnetic steel temperature limiter loss of excitation is disconnected, magnetic steel temperature limiter also disconnects by lever drives magnet steel temperature limit switch, the heating of heat-generating disc outage stopping at this moment.This automatic electric rice cooker has good characteristics such as esy to use, safe and reliable, durable in use, but also exist not enough be: can not reduce or increase load as required, it is bigger to dispel the heat all around, and the thermal efficiency is not high.
The purpose of this utility model provides a kind of energy-saving heat preserving formula automatic electric rice cooker, and it can not only reduce or increase load as required, and can reduce the heat radiation all around of electric cooker, can reach the purpose of saves energy effectively.
The purpose of this utility model is achieved in that buries a heat-generating pipe underground in the heat-generating disc, another utmost point of the utmost point of supply socket, magnet steel temperature limit switch, heat-generating pipe, supply socket is linked in sequence, in heat-generating disc, increase and bury a heat-generating pipe underground, one utmost point of supply socket is electrically connected with a contact of magnet steel temperature limit switch, another contact of magnet steel temperature limit switch is electrically connected with a contact of selector switch, another contact of selector switch is electrically connected with an end of heat-generating pipe, and the other end of heat-generating pipe is electrically connected with another utmost point of supply socket.Around electric cooker, bottom, pot cover be incubated with insulation material.During use, power supply is connected in supply socket, the magnet steel temperature limit switch closes, a heat-generating pipe heating power in the heat-generating disc, increase also heating power of this root heat-generating pipe of burying underground in the selector switch that then closes, heat-generating disc, after food boils and rises, disconnect selector switch, just have only a heat-generating pipe heating to keep boiling in the heat-generating disc.
Electricity is in adopting such scheme, and operating selection switch reduces or increases load as required, thereby reaches purpose of energy saving, only increases in heat-generating disc and has buried a heat-generating pipe underground, around electric cooker, bottom, pot cover be incubated with insulation material.Simple structure, easy to operate, durable in use.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is an electrical schematic diagram of the present utility model.
Fig. 2 is a vertical section of the present utility model structural map.
R1, R2---be embedded in two heat-generating pipes in the heat-generating disc (6);
R3, R4---indicator lamp dropping resistor;
ZSD1---the indicator lamp of cooking; ZSD2---insulation indicator lamp;
AN1---magnet steel temperature limit switch; This switch is made up of a button, magnetic steel temperature limiter work when closing, and the magnetic steel temperature limiter action drives this switch automatic disconnection, and Fig. 2 (12) is a button.
AN2---selector switch; This switch is made up of two buttons, and Fig. 2 (11) is to close, and (10) are branches.
XW---magnetic steel temperature limiter; Fig. 2 (7).
R5---resistance-type insulation electricity consumption.
