Description

Gas stove switch timing means capable of automatic assembling

Technical field

The utility model relates to a kind of gas stove switch timing means, refers to a kind of various gas stove switch that is applicable to especially, assemble voluntarily by the user, and the design of the timing means of function such as tool clutch for clutch control.

Background technology

The switch of early stage gas furnace only possesses the function of the control of the switch of stove fire and flame size, because people stew because of the long-time slow fire of need for some food and boil, or situation such as busy need kitchen away from keyboard, therefore, people delay having forgotten the time because of thing sometimes, and food is still arranged in boiling on the gas furnace, cause food excessively can not be eaten or the dangerous situation of boilers from drying burning by boiling.

For this reason, someone successively designs the switch of all kinds gas furnace, as No. the 14089th, TaiWan, China patent announcement " regular automatical shutoff device of gas furnace ", announce No. 94421 by " gas furnace self-timing shutoff device ", announce No. 112217 " the gas furnace self-timing stops the stove fire device ", announce No. 174442 " improvement of gas furnace timing means ", announce No. 212203 " timing control apparatus of gas furnace ", announce No. 222809 " watt stove and accessory of tool timing means ", announce No. 296040 by " automatic timer of gas furnace ", announce No. 344444 by " the safety fuel gas stove of tool timing music caution ", announce No. 353510 " gas furnace mechanical type timing control apparatus ", announce No. 433439 " the safety fuel gas stove of tool timing " and announce shown in No. 443474 many novel patent cases such as " improvement of gas furnace timing valve device construction ", in order to the device that provides user one can the timing controlled stove fire to close automatically.

By learning in the above-mentioned known gas stove switch timing means structure, no matter each timing means is to integrally combine with the stove fire switch or the separate type design, need by the manufacturer before the gas furnace shipment, finish through professional's assembling, therefore, the original gas stove switch that uses of consumer does not possess timing function, if want to make gas furnace to possess the timing automatic function of closing of stove fire, promptly need existing gas furnace is abandoned, change another one and possess the new gas furnace of closing stove fire automatically, this mode has the suspicion of waste for consumers in fact.

Secondly, above-mentioned each timing means is the gas stove switch interlock that integrally combines, the structure that does not possess clutch for clutch control, even if that is the user does not set the stove fire shut-in time, when only operating gas stove switch control gas furnace stove fire, this timing means also can be activated simultaneously, and because during people's cooked food, the all operations in the kitchen of this section period, or only merely leftovers is heated, do not need special setting, therefore, this timing means is activated at this moment, cause the user to operate greatest inconvenience, and because of the knob of gas furnace control stove fire switch and size often by turn, do the above-mentioned correction of unnecessary action so related timing means is driven, therefore cause this timing means that the situation of lacking partially service life is arranged.

Summary of the invention

In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of clutch for clutch control function that has, and allows the user select regularly to close stove fire whether gas stove switch timing means capable of automatic assembling voluntarily.
