Abstract

The utility model relates to a safety automatic turning off device for a gas combustion stove, which belongs to the technical field of a regulating and controlling device for combustion. When the utility model is used and the time reaches the preset fire needing time, gas can be automatic turned off, causing that the fire is extinguished. The utility model is characterized in that the utility model is that an electromagnetic valve is connected with a circuit composed of a loudspeaker, an indicating lamp, a motor, a switch and a timing switch. The utility model has the advantages of simple structure and high safety. When the utility model is arranged on the gas combustion stove, cooked food can be assured; the timing for automatic gas turning off can be carried out after cooking is completed; thereby, time can be saved.

Description

Gas-cooker safety automatic gas-off device

The utility model belongs to the adjusting or the control device technical field of burning.

During housework such as people cook in the kitchen in daily life, cooking, stewing soup, must wait in the kitchen.Otherwise accidentally just close the fire burning foods or burn out apparatus because of forgetting.Also have because the not enough food of the duration and degree of heating is not yet done or dull.Have, waiting for can not employ one's time to the best advantage in the kitchen does other housework again.

The purpose of this utility model is to provide-kind of gas-cooker safety automatic gas-off device, needs the fire time one to arrive when preestablishing, and then promptly closes the gas fire automatically and goes out.

The utility model is finished with following mode: feature is that it is by loudspeaker Y, indicator lamp L ₁L ₂L ₃, motor M, K switch ₁K ₂, time switch K _3ABThe circuit of forming is loaded in the box or is loaded on that gas-cooker is connected with magnetic valve 3 and the device that constitutes; K switch ₁Connect civil power 0～220 And connect time switch K _3ABBe connected indicator lamp L ₃, this indicator lamp L ₃Respectively with motor M, indicator lamp L ₂, magnetic valve 3 connects loudspeaker Y magnetic valve 3, the indicator lamp L of inserting in parallel ₁The loudspeaker Y that inserts in parallel, magnetic valve 3 connects time switch K _3ABIndicator lamp L ₂Also be connected with motor M; K switch ₂Together with motor M, time switch K _3ABBe connected.

The utility model is simple in structure, and is safe and reliable.Be loaded on can guarantee on the gas-cooker that food boils can timing automatic on demand pass gas after cooked, provide convenience, save time to people.

The detailed description of in conjunction with the accompanying drawings the utility model being done into-being gone on foot now.

Fig. 1 is structural representation of the present utility model and user mode figure.

With reference to Fig. 1, be example with the oil liquefied gas kitchen range, this device circuit is loaded in the box or is loaded in the gas-cooker 4, only needs magnetic valve 3 is connected on the air inlet pipe of gas-cooker 4.During use, enter gas-cooker 4 through magnetic valve 3 by the oil liquefied gas in the gas cylinder 1 again through pressure-reducing valve 2 and use for burning.Cooking, when cooking, simmering Tang Renxu and leaving the kitchen, use this device operation principle as follows: with K switch ₁Close and connect city's power supply, time switch K _3ABFix on the required time, at this moment time switch K _3ABEnter that SBR makes the A closure and B disconnects, when apparatus such as pressure cooker reach initial temperature, steam apparatus sound makes K switch ₂Close, motor M starts running, after predetermined required time arrives, and time switch K _3ABMake the B closure and the A disconnection, at this moment magnetic valve 3 is activated and cuts out, thereby closes gas automatically.Meanwhile, indicator lamp L ₁Bright and loudspeaker Y sends tweeting sound.Indicator lamp L ₁, L ₂Be respectively applied for motor M, time switch K _3ABAction show.When being used for boiling, the utility model sends kitchen utensils such as the sound such as pressure cooker with prodigiosin.
