Abstract

The utility model relates to a timing alarming power-off device for a universal electric rice cooker. The utility model can switch on or switch off the electric rice cooker according to the water quantity in the cooker and the degree of soft and hard of the rice when a housewife cooks. The output end of the utility model is connected with a power plug of the electric rice cooker, the input end of the utility model is connected with AC 220 V electric voltage, and the input end of the utility model is simultaneously connected with the timing alarming power-off device which is connection in series with a buzzer. The utility model has the advantages of simple structure and convenient operation. The timing alarming power-off device for the universal electric rice cooker is an ideal article which is necessary in a domestic kitchen.

Description

The timing alarm circuit breaker that ordinary electric rice cooker is used

The utility model relates to the timing alarm circuit breaker that a kind of family ordinary electric rice cooker is used.

At present, when the family expenses ordinary electric rice cooker is cooked, after connecting power supply, just work always, can't make the electric cooker outage work that stops doing business according to the soft or hard that the water yield in the pot what or the people that cooks like eating rice, the meal that electric cooker is cooked be not suitable for sometimes cooking people's taste, sometimes hard or soft, bring worry for housewifves.

The purpose of this utility model is the deficiency that exists according to existing ordinary electric rice cooker, proposes a kind of timing alarm circuit breaker, and the people that cooks controls the electric cooker power on/off according to the soft or hard of the water yield in the pot and rice.

The purpose of this utility model is achieved in that mainly by timing alarm circuit breaker and buzzer K and indicator lamp T ₁, T ₂And resistance R ₁, R ₂And fuse W forms, and input of the present utility model connects the power supply of alternating current 220V, an end of input respectively with timing alarm circuit breaker and indicator lamp T ₁Link to each other indicator lamp T ₁And resistance R ₁One end links to each other, the other end of input respectively with fuse W and resistance R ₁The other end link to each other, the other end of fuse W then respectively with buzzer K one end, resistance R ₂One end and output link to each other, and the other end of buzzer K links to each other with an end of timing alarm circuit breaker, the output of timing alarm circuit breaker respectively with indicator lamp T ₂And output links to each other indicator lamp T ₂The other end then and resistance R ₂An end link to each other resistance R ₂The other end link to each other with output.Timing alarm circuit breaker in the utility model is to form like this, central shaft 14 is multilayer step axles, left end is thick, right-hand member is thin, left end has a turn-knob 15, spacer pin 13 is arranged below turn-knob 15, spring 11 is contained in the barrel 12, and barrel 12 is fixed on the left-side bottom 10, and clockwork 16 is in the middle of left-side bottom 10 and right side base plate 17, cam 5 and cam 6 are installed in the right-hand member of central shaft 14, rotation push rod 8 is on cam 6, and rotation push rod 9 is on cam 5, and driving lever 7 is fixed on central shaft 14 right-hand members, stir cam 5 by synchronous rotational speed, 6, rotation push rod 8 and rotation push rod 9 join when working with the relay contact.Operation principle of the present utility model is: when cooking with electric cooker, at first the attaching plug of electric cooker is received output of the present utility model, input termination alternating current 220V voltage of the present utility model, electric cooker is started working, in the middle of cooking, stiff a bit when opening electric cooker as finding rice, water after a little while, with turning on the timing alarm circuit breaker, electric cooker is regularly cut off the power supply, utilize waste heat in the pot this moment, holding temperature, when power-off time one arrives, buzzer K sends the prompting sound, and electric cooker is connected power supply and worked on.

Contact

1,2 is a normally-closed contact, and contact 3,4 is a normally opened contact, and when turn-knob 15 turns, throw off

contact

1,2, contact 3,4 contacts, this moment electric current I ₁=0, I ₂=0, two cam jack-up are come, and timer is started working, when timing one arrives, and contact 1,2 contacts, contact, electric current I are continued in

contact

3,4 ₁Electricity is arranged, I ₂Electricity is arranged, and at this moment buzzer K reports to the police.

The utility model is simple in structure, and is easy to use, can solve effectively the housewife when cooking to the overflow phenomenon of pot of the uncontrollable soft or hard of rice in the pot and congee.
