Abstract

The utility model relates to an electronic timing switch for a gas stove, which is provided with an electronic timer; a power switch of the electronic timer is a linking contact switch arranged on a switch for a gas stove. The utility model can realize the timing prompting function after the switch for gas stove is opened. The utility model can also restart a timer and regulate the timing time at any time when the gas is used, realizing the timing prompting in the process of cooking some one boiled object. If the timing is not required, the timer can be turned off. The utility model realizes self-timing prompting function and has the advantages of convenient operation, flexibility, and safety.

Description

A kind of electronic timing gas stove switch

The utility model is a kind of electronic timing gas stove switch, and it can open the function that the back realizes that regularly newspaper is named at gas stove switch.

In prior art, Chinese patent has been announced many timing burnt gas switchs, and they mostly are to finish the function that timing automatic is closed.Regularly closing is a kind of compulsory safety measure, for the user, not necessarily needs enforceable closing sometimes, and only needs suitably regularly to remind, and like this, can guarantee safety, can continue follow-up culinary art again, need not drive valve again again.Therefore, the burnt gas switch that this timing is closed needs the users that regularly remind just not too suitable to those, can not reach not only convenient, but also the application requirements of safety.

The purpose of this utility model is at the problem in the prior art, provides a kind of and can regularly report the electronic timing gas stove switch that cries.

For achieving the above object, solution of the present utility model is as follows: it has a gas-cooker machinery switch, also set up an electronic timer, the mains switch of this electronic timer is made of a linked contact switch that is located on the described gas-cooker machinery switch.

By above-mentioned solution as can be seen, the utility model has been set up a kind of electronic timer on existing gas-cooker machinery switch, and the mains switch of this electronic timer and gas-cooker machinery switch gearing, when combustion gas machinery switch opens, the mains switch of electronic timer also starts working timer thereupon closure, when timing one arrives, it just sends tweeting sound and reminds the user, thereby the self-timing newspaper of realizing whole cooking time is named; Simultaneously, the user also can be in cooking process any one restart timer constantly and regulate timing, cries with the timing newspaper of realizing a certain single Stewed Dish in the cooking process, if when not preferring, can also turn-off timer.The utility model has been realized regularly reporting the function of being the user, and easy to operate, flexible, safety.

Below according to realizing example explanation structure of the present utility model and operation principle.

Fig. 1, overall structure schematic diagram of the present utility model.

The A-A face diagrammatic sketch of Fig. 2, Fig. 1.

Two of Fig. 3, linked contact switch structure figure.

The A-A face structure chart of Fig. 4, Fig. 3.

Three of the structure chart of Fig. 5, linked contact switch.

Four of the structure chart of Fig. 6, linked contact switch.

The circuit theory diagrams of Fig. 7, electronic timer.

Referring to Fig. 1,2, described linked contact switch constitutes by being located at contact 1 on the gas stove switch axostylus axostyle 3 and the ring type contact 2 that is located on the panel 4.When gas stove switch is opened, axostylus axostyle 3 clockwise or rotate counterclockwise and rest on a certain position, then contact 1 contacts with ring type contact 2 and closure, electronic timer is started working.

Referring to Fig. 3,4, ring type contact among Fig. 1 can also replace with a kind of flange shell-like contact 6, and contact can replace with the contact 5 of the projection on the axostylus axostyle, coat insulating varnish on the circle wall of axostylus axostyle except that the contact, mechanical switch described contact when closure is not contacted with contact, and when the axostylus axostyle up time or when rotating counterclockwise, contact 5 contacts with contact 6 and closed.

Referring to Fig. 5, the ring type contact among Fig. 1 can also replace with taper elastic contact blade 7, and axostylus axostyle is provided with the contact 7 of projection, and scribbles insulating varnish on axostylus axostyle.

Referring to Fig. 6, described linked contact switch is made of a fixed contact 16, swing contact 17 and the extension spring 18 of be connected and fixed contact and swing contact and the shifting block 19 that is located in the rotating shaft of gas-cooker machinery switch.The relative switch hole limit that is installed in the gas-cooker panel of described fixed contact with swing contact.When gas stove switch is in the position of closing, shifting block 19 with 17 groups of swing contact from, it is not contacted with fixed contact; And open when gas stove switch is switch shaft during to counter clockwise direction, and shifting block rotates thereupon, and then swing contact resets under the effect of extension spring 18, contacts with fixed contact, and timer is started working.

If the afterbody of gas stove switch has living space, also can adopt a knob type switch, wherein the axostylus axostyle of rotation axis and gas stove switch links, and switch body is fixed on the kitchen range shell.When gas stove switch is opened, but the servo-actuated of knob type switch and closure.

The circuit form of electronic timer described in the utility model is a lot, and in general, existing timing and delayer can both be applicable to the utility model, only the mains switch of timing or delayer need be changed to above-mentioned linked switch and get final product.This example has adopted one than general purpose timer, its circuit structure is referring to Fig. 3, it is is mainly connected and composed by delay circuit 8, oscillator 11 and the loud speaker 12 that is connected on oscillator output end, and wherein the potentiometer in the delay circuit 9 is used to regulate delay time, and button 10 is the knobs that reset of this delay circuit; Oscillator 11 also can adopt integrated devices such as various music, voice etc.; Switch 13 in the circuit is above-mentioned linked contact switch, and in parallel with it is self check push switch 14, series connection with it be normally closed switch 15.Its operation principle is: when burnt gas switch was opened, mains switch 13 was closed thereupon, then delay circuit 8 triggers, delay time one arrives, it makes oscillator 11 work just from triggering signal of 3 pin output, and the oscillator signal of its output drives the tweeting sound that loud speaker 12 sends interruption.In when culinary art, can press knob 10 at any time, then delay circuit restarts and carries out new time-delay; Can change delay time by regulator potentiometer 9.In addition, when combustion gas is not opened, can press 14 pairs of these timing circuits of self check knob and carry out self check; Disconnect normally closed switch 15 electronic timer is quit work, recover common combustion gas user mode.
