Abstract
The utility model relates to a heat-insulating and energy-saving electric rice cooker which belongs to the technical field of household appliances. The utility model is composed of a casing, a heating plate, a rice holding box, a cover and an electronic circuit, and is characterized in that a high-power semiconductor rectifying diode is connected with a heat retainer contact in series in a heat-insulating circuit. The utility model has the advantages of simple structure, easy installation and low cost. In addition, electricity can be saved for more than 80% in the heat insulating stage of the heat-insulating and energy-saving electric rice cooker.
Description
A kind of heat-preserving energy-saving type electric cooker belongs to household electrical appliance technical field.
The holding stage of existing electric cooker after meal is ripe on the market all is to connect circuit by warmer contact (5) total power.As 700 watts electric cooker, be 700 watts when cooking, also be 700 watts during insulation.Become coke yellow so usually make meal stick with paste the end, particularly temperature retention time is a little longer, and as 20 minutes, then the sallow area in the bottom of a pan was just bigger.A period of time that also usually will be soaked in water when washing the meal basin can be cleaned, so the more time-consuming electricity that takes, the meal quality of boiling is also relatively poor.
The purpose of this utility model be reduce electric cooker in the electrical power of holding stage to reach the electricity saving and energy saving purpose.
The technical solution of the utility model is in the electric cooker thermal circuit, seals in a high power semi-conductor commutation diode (6) more than 2 amperes with warmer contact (5).
Accompanying drawing is the electrical schematic diagram of heat-preserving energy-saving type electric cooker.Sequence number among the figure (1) is a heat-generating disc, and (2) are power supply indication neon lamp, and (3) are current-limiting resistance, and (4) are the magnetic steel temperature limiter contact, and (5) are the warmer contact, and (6) are the high power semi-conductor commutation diode.
Further set forth its operation principle below in conjunction with accompanying drawing.When cooking, the series circuit short circuit by magnetic steel temperature limiter contact (4) form warmer contact (5) and semiconductor rectifier diode (6) makes it inoperative when cooking.After meal boiled, because the tripping of magnetic steel temperature limiter contact, warmer contact and semiconductor rectifier diode (6) just sealed in the insulation loop of electric cooker.Because of semiconductor rectifier diode (6) plays the halfwave rectifier effect in the insulation loop, its output voltage has only 0.45 times of supply voltage.Power is (0.45)
2Doubly, be 20% of former power, economize on electricity 80%.Do not stick with paste at the end through the meal after the insulation in 1 hour, do not have sallow phenomenon and reached and give the phase effect, overcome the shortcoming of former electric cooker.
With every electric cooker power is 700 watts, in every day, dinner respectively boils meal one time, is incubated 10 minutes at every turn and calculates for example.Be incubated 20 fens kinds every day, accumulative total insulation in 3 days is 1 hour, economizes on electricity 700 * 80%=560 watt=0.56 kilowatt 0.56 * 10=5.6 kilowatt/hour of economize on electricity in 30 days every month.The whole nation then can be 5.6 kilowatts/hour * 1000000=560 of country's economize on electricity, ten thousand degree electricity, obvious social benefit in every month for calculating with 1,000,000 electric cookers.
Present technique also has 3 characteristics: (1) is easy for installation, need only change a wiring. (2) cost is low, is no more than 3 yuans. (3) do not destroy structure and the profile of former electric cooker.
Claims (1)
1, a kind of heat-preserving energy-saving type electric cooker is made up of housing, heat-generating disc (1), the basin of filling a bowl with rice, lid, electronic circuit, it is characterized in that in thermal circuit, seals in a high power semi-conductor commutation diode (6) more than 2 amperes with warmer contact (5).
