Description

Energy-saving electric cooker

Technical field

The utility model belongs to a kind of kitchen electric equipment, is specifically related to a kind of electric cooker.

Background technology

At present, at the electric cooker that occurs on the market, mainly by pot cover, shell, internal layer, inner bag, control panel, magnetic steel temperature limiter, heat-generating disc, the insulation sheet, after electric cooker connection power supply is pressed heater switch, pogo stick promotes the thimble of magnetic steel temperature limiter, the pulling pogo stick that attracts each other of two magnetic sheets in the electric cooker magnetic steel temperature limiter, pogo stick further makes the contact of steel disc contact, heat-generating disc begins heating work, when reaching the design temperature of magnetic steel temperature limiter, magnetic sheet in the magnet steel loses magnetism, contained spring can make magnetic sheet separate, the thimble of magnetic steel temperature limiter can promote pogo stick makes the steel disc contact separately, thereby disconnect heater circuit and make it to be in keeping warm mode, this shows that electric cooker is in process is cooked in heating, no matter how many heats inner bag can absorb, the power of electric cooker output remains constant, after material boiling in the electric cooker, the power of actual needs electric cooker output can reduce, and wastes thereby make heat-generating disc send unnecessary heat, and unnecessary heat energy makes the internal layer temperature in the pot very high, iron plate in the pot also is very easy to get rusty, and simultaneously, electric power connection line is easy to wear out, therefore, existing electric cooker is not only wasted electric energy but also is not durable.

The utility model content

Constant all the time and cause the waste problem much larger than the actual power demand of inner bag because of power output in digestion process in order to solve existing electric cooker, the purpose of this utility model is to provide a kind of electric energy and more durable electric cooker saved.

For achieving the above object, the technical scheme that the utility model adopted is:

A kind of energy-saving electric cooker, comprise pot cover, shell, internal layer, inner bag, control panel, magnetic steel temperature limiter, heat-generating disc, the insulation sheet, control panel and magnetic steel temperature limiter, heat-generating disc and insulation sheet constitute electric cooker thermal circuit and heater circuit jointly, described heater circuit is by heating contact switch (K1), heat-generating disc (R3), fusing fuse (F1) is held the formation of connecting with AC input L end with N, it is characterized in that: be connected in series a Kick type temperature controller (K2) again, Kick type temperature controller (K2) two ends crystal diode (D1) in parallel between described heat-generating disc (R3) and heating contact switch (K1).

Preferably, described Kick type temperature controller (K2) is arranged at the gap of heat-generating disc below or internal layer and inner bag sidewall.

Preferably, described pot cover below is provided with a metal-back, and described Kick type temperature controller (K2) is located in the metal-back of pot cover

Preferably, described inner bag is individual layer stainless steel inner container or ceramic liner.

After the utility model connection power supply is pressed the switch of cooking, the heating contact switch K1 closure of electric cooker, heater circuit is started working, heat-generating disc begins heating inner bag is heated, when the water temperature in the electric cooker reaches 80 ℃～100 ℃, Kick type temperature controller K2 disconnects, crystal diode D1 starts working thereupon, because crystal diode D1 has forward conduction, the characteristic of oppositely ending, therefore, this heater circuit is equivalent to a half-wave rectifying circuit, and it is original 1/2 that the voltage effective value of supplying with heat-generating disc is reduced to, the heat kept in balance that heat that this moment, heat-generating disc sent and inner bag absorb, thereby reached higher efficient, compare economize on electricity with existing electric cooker about 30%, and electric cooker internal layer temperature reduces about 50% than existing electric cooker temperature simultaneously, thereby iron plate and power line life-span in the pot are longer.
