Abstract
The utility model relates to a double firepower rice cooker which belongs to the filed of household appliances. Compared with the prior common rice cooker, a larger improvement is provided for the circuit structure: the bottom of an electric plate is provided with two tubular electrical heating elements R1 and R2 with different powers, the total power is obviously more than that of the common rice cooker with same capacity, and the small power is also obviously less than that of the common rice cooker with same capacity; the two tubular electrical heating elements are connected with a magnetic steel temperature limiter K1 with 90-100 degrees of Curie point operating temperature in series, and the tubular electric heating element R2 with smaller power is also connected with a time delay switch K2 and a heat insulation switch K3 in series. The utility model has the advantages that the time is saved before water is boiled, half-cooked rice can be avoided being cooked, the phenomenon of rice sticking and overflowing the cooker is reduced after water is boiled, and the heating time of the small power can be adjusted according to the demands.
Description
Technical field
The utility model relates to the electric cooker field.
Background technology
Known electric cooker is mainly formed (when in the electric cooker during a more than electric hot tray, referring to prominent main electric hot tray) by housing, interior pot, electric hot tray and control circuit.Electric hot tray generally is made up of the single tubular electrothermal element of heat conduction disk body and bottom.Control circuit mainly is made up of a magnetic steel temperature limiter and an insulation switch.Its weak point is to have only a kind of power of continuous heating, and water dislikes firepower little before boiling, and loses time, cook cause more easily cook half-cooked; Dislike firepower big after water boils, the sticking easily pot and the pot that overflows are wasted electric energy simultaneously; And be not suitable for Baoshang.Though some intelligent electric cooker also possesses more than a kind of continuous heating power, structure is comparatively complicated, lacks economy and reliability.
The utility model content
The purpose of this utility model provides a kind of pair of firepower electric cooker at the above-mentioned weak point of present electric cooker exactly.
The utility model comprises electric hot tray and control circuit.The electric hot tray bottom is provided with two tubular electrothermal element R1 and R2, and control circuit comprises magnetic steel temperature limiter K1, delay switch K2 and insulation K switch 3, and the curie point operating temperature of magnetic steel temperature limiter K1 is 90 ℃～100 ℃.Connect two tubular electrothermal element R1 by magnetic steel temperature limiter K1 before water boils and R2 works simultaneously, boil and water is connected lower-powered tubular electrothermal element R2 by delay switch K2 after boiling and worked on a period of time near water.
The utility model has the advantages that: use big fire to save time before water boils, and can improve the palatability of food; Use little fire can reduce the sticking pot and the pot that overflows after water boils, and save electric energy; The cooperation that adds the delay switch that can adjust time span also is fit to Baoshang very much, cook congee, boil milk and soya-bean milk, boil water etc.Possess above-mentioned advantage than common electric cooker, possess economy and reliability than intelligent electric cooker.
Description of drawings
Accompanying drawing 1 is the utility model circuit diagram
The specific embodiment
Inventive concept of the present utility model is that the general configuration of existing electric cooker is constant, (with existing 4 liters of 600 watts of electric cookers is example to change the single tubular electrothermal element of electric hot tray bottom two tubular electrothermal elements of different capacity into, can change 1000 watts into and add 200 watts), and correspondingly change control circuit.During concrete enforcement two tubular electrothermal element R1 and R2 be installed in different zone, electric hot tray bottom; The curie point operating temperature of magnetic steel temperature limiter K1 is 90 ℃～100 ℃, and the time span of delay switch K2 can be adjusted; Magnetic steel temperature limiter K1, delay switch K2 and 3 parallel connections of insulation K switch, two tubular electrothermal element R1 and R2 by separately independently conductive contact connect with magnetic steel temperature limiter K1, lower-powered tubular electrothermal element R2 also respectively with delay switch K2 be incubated K switch 3 and connect.Lever far-end at magnetic steel temperature limiter K1 is provided with an elasticity touching part, touches the starting switch of delay switch K2 during tripping by inertia.During the beginning cook food, magnetic steel temperature limiter K1 connects two tubular electrothermal element R1 and R2 works simultaneously with parallel way, when the temperature of interior pot bottom is raised to 90 ℃～100 ℃, and the automatic tripping of magnetic steel temperature limiter K1; Automatically start delay switch K2 during magnetic steel temperature limiter K1 tripping, delay switch K2 connects lower-powered tubular electrothermal element R2 and works on, if cook then work about 10 minutes, if Baoshang then manually set the corresponding time; When the electric hot tray temperature was lower than 65 ℃ of left and right sides, the lower-powered tubular electrothermal element R2 of insulation K switch 3 controls was incubated; When attemperating unit break down or improper start delay switch K2 after, when causing the electric hot tray temperature too high, two tubular electrothermal element R1 of overtemperature prote device T automatic disconnection and R2.
Claims (2)
1, a kind of pair of firepower electric cooker mainly is made up of housing, interior pot, electric hot tray and control circuit, it is characterized in that being provided with bottom the electric hot tray two the tubular electrothermal element R1 and the R2 of different capacity; Control circuit comprises a magnetic steel temperature limiter K1 and a delay switch K2 at least; The curie point operating temperature of magnetic steel temperature limiter K1 is 90 ℃～100 ℃; Two tubular electrothermal element R1 and R2 all connect with magnetic steel temperature limiter K1, and lower-powered tubular electrothermal element R2 also connects with delay switch K2.
2, according to claim 1 pair of firepower electric cooker is characterized in that referring to prominent main electric hot tray when in the electric cooker during a more than electric hot tray.
