Description

A kind of energy timing power supply and the electric cooker that cuts off the power supply automatically

Technical field

The electric cooker that the utility model relates to a kind of energy timing power supply and cuts off the power supply automatically belongs to the electric heating cooker technical field.

Background technology

Electric cooker is the household electrical appliance commonly used during people live, and common electric cooker all has automatic meal braizing and heat insulation function at present, brings great convenience for people's life.Reservation is regularly steamed, rice-cooking function but general electric cooker does not have, after in a single day operating personnel connect the electric cooker power supply, electric cooker enters steaming immediately, cooks or keeping warm mode, and operating personnel can't not realize that reservation is regularly steamed, rice-cooking function at the scene the time, therefore make troubles to operating personnel; Ordinary electric rice cooker steams in addition, cooking to finish to cut off the electricity supply to operating personnel to be in keeping warm mode for a long time, at this moment not only wastes electric energy but also be unfavorable for safety.Though the high-grade electric cooker that also has on the market possesses timing power supply and automatic circuit break function now, the technical scheme complexity, manufacturing cost is higher.

Summary of the invention

The electric cooker that technical problem to be solved in the utility model provides a kind of energy timing power supply and cuts off the power supply automatically, and have advantage simple in structure, esy to use, safe and reliable, energy-conservation, with low cost.

The technical scheme that realizes the foregoing invention purpose is:

A kind of energy timing power supply and the electric cooker that cuts off the power supply automatically, it is made of pot cover, pot body, steamed rice insulation change-over switch, insulation indicator lamp, steamed rice indicator lamp, electric hot tray, preheating table, temperature control resistance, magnet steel, power line, its improvements are, electric cooker also is equipped with the power supply timer switch, one end of power supply timer switch is connected with the power supply line, and the other end is connected with steamed rice insulation change-over switch feeder ear.

Above-mentioned energy timing power supply and the electric cooker that cuts off the power supply automatically, it also has breaker timing device switch, and an end of breaker timing device switch is connected with steamed rice insulation change-over switch one end, and the other end is connected with preheating table.

Above-mentioned energy timing power supply and the electric cooker that cuts off the power supply automatically, the switching knob of described power supply timer switch and breaker timing device switch is installed on the lateral wall of electric cooker pot body.

The utility model has been realized timing automatic opening and closing electric cooker power supply function by installation power supply timer switch and breaker timing device switch on ordinary electric rice cooker, solved ordinary electric rice cooker do not have reservation regularly steam, cook and steam, cook finish after powered-down problem automatically, have advantage simple in structure, esy to use, safe and reliable, energy-conservation, with low cost, good market prospects are arranged.

Description of drawings:

Fig. 1 is a schematic appearance of the present utility model;

Fig. 2 is an electric functional-block diagram of the present utility model;

Fig. 3 is an electrical schematic diagram of the present utility model.

Mark among the figure: pot cover 1, pot drawer 2, pot body 3, breaker timing device switch 4, power supply timer switch 5, steamed rice insulation change-over switch 6, insulation indicator lamp 7, steamed rice indicator lamp 8, power line 9, electric hot tray 10, preheating table 11, temperature control resistance 12, power supply 13, magnet steel 14.

The specific embodiment

Show among the figure, the electric cooker of this energy timing power supply and outage automatically is made of pot cover 1, pot drawer 2, pot body 3, breaker timing device switch 4 (K3), power supply timer switch 5 (K1), steamed rice insulation change-over switch 6 (K2), insulation indicator lamp 7 (XD1), steamed rice indicator lamp 8 (XD2), electric hot tray 10 (E), preheating table 11 (C), temperature control resistance 12 (RK), magnet steel 14 and power line 9, and wherein breaker timing device switch 4, the timer switch 5 of powering are that the utility model is than the peculiar device of general electric cooker.

Fig. 3 is an electrical schematic diagram of the present utility model, the end of power supply timer switch K1 is connected with plug XP among the figure, the other end is connected with the 1st pin of steamed rice insulation change-over switch K2, be feeder ear, the 2nd pin of steamed rice insulation change-over switch K2 is connected with electric hot tray E, the other end of electric hot tray E is connected with temperature control resistance R K, the 3rd pin of steamed rice insulation change-over switch K2 is connected with an end of breaker timing device K switch 3, the other end of breaker timing device K switch 3 is connected with preheating table C, the other end of preheating table C is connected with the feeder ear of electric hot tray E, so just constituted the heating control loop of electric cooker system, mixed steamed rice indicator lamp XD2 again and both constituted complete electric cooker control circuit with insulation indicator lamp XD1.

Its course of work: after electric cooker power line 9 was connected power supply, by the delay time that the power supply of power supply timer switch K1 control electric cooker needs, delay time was manually set by operating personnel, if do not set power supply timer switch K1, then delay time is zero.After delay time arrived, power supply timer switch K1 connected.At this moment if steamed rice insulation change-over switch K2 is chosen in the steamed rice position, electric cooker begins steamed rice.After electric cooker steamed rice process finished, steamed rice insulation change-over switch K2 transferred the connection of insulation contact automatically under the effect of magnet steel 14, and the steamed rice contact disconnects, i.e. 2 pin of steamed rice insulation change-over switch K2 disconnect, and 3 pin are connected.After this time of breaker timing device K switch 3 being set according to operating personnel is controlled temperature retention time, if do not set breaker timing device K switch 3, then temperature retention time is zero.After the time that breaker timing device K switch 3 is set arrived, breaker timing device K switch 3 was cut off the insulation power supply automatically, makes electric cooker be in off-position.Just realize timing automatic opening and closing electric cooker power supply function by power supply timer switch K1 and breaker timing device K switch 3 like this, reached easy to use, energy-conservation simultaneously and improved the purpose of security.

When using this electric cooker, the first step should be put into electric cooker with the Mi Heshui that cooks in advance earlier, builds pot cover; Second step was set power supply timer switch 5 to needed delay time; The 3rd step was incubated change-over switch 6 with steamed rice and is arranged on the steamed rice position; The time that the 4th step was incubated as required is provided with breaker timing device switch 4, and the time of breaker timing device switch 4 settings at this moment should be time, steamed rice required time, the insulation required time sum that power supply timer switch 5 is set; The 5th step was connected power supply by power line 9.Operating personnel are by above five steps operation, and automatic electric rice cooker just can be finished the whole predetermined process of cooking of steamed rice insulation automatically in official hour, cut off the electricity supply automatically after the end.
