Description

Combustion gas, fuel oil automatic rice cooker

The application to as if belong to a kind of valve self closing device of household electrical appliance, combustion gas or fuel oil stove and accessory industry.

Before the application, background technology is that known domestic gas or fuel oil stove and accessory valve are manual substantially, with pot heat up water or during cooking by manual time-keeping, monitor combustion case, need after finishing with manual-lock stove and accessory valve, not only elapsed time but also fritter away energy, as the untimely stove and accessory valve of closing, also can cause waste combustion gas or fuel oil, even have an accident.In addition, known sound-controlled apparatus and timer seldom are used on domestic gas or the fuel oil stove and accessory.

The purpose of the application's object is for the pot for cooking rice that makes combustion gas or fuel oil, steamer, pressure cooker, kettle etc., below is referred to as pot for cooking rice, closes air inlet or oil-feed valve in official hour automatically.

The application's task is finished as follows: the one, load onto the gas whistle that is at least with having the pot for cooking rice body of prescribed strength or covering; The 2nd, on the air intake valve of known combustion gas or fuel oil stove and accessory, load onto known servo, or directly use known magnetic valve; The 3rd, on servo or magnetic valve, load onto known timer; The 4th, on timer, must load onto known sound-controlled apparatus, can also load onto the recoil simulator of buzzer, indicator lamp one class, the recoil simulator of not adorning buzzer and indicator lamp one class certainly also can.This device is powered by external power supply.During use, pot for cooking rice is placed on the commercially available stove and accessory and with sound-controlled apparatus remains in the operating distance of regulation.When with combustion gas or fuel oil pot for cooking rice cooking or when liquid such as heating up water, at first connect the external power supply of this device, open air intake valve with manual knob thereafter, also can manual knob be set certainly and adopt electronicly, open air intake valve; Simultaneously by the required time, be that water or liquid boiling or food boil time or time set timer rule of thumb, this moment, timer did not pick up counting, then turn stove and accessory switching point burner tool, certainly also the stove and accessory switch can be set, and when opening air intake valve, light stove and accessory.When the temperature in the pot for cooking rice reaches boiling point and promptly boils, steam pressure in the pot makes the sound-producing device of the gas whistle one class send sound, by after the sound-controlled apparatus reception timer being started, the timer work that picks up counting this moment, when arriving the time of setting, timer is connected servo or power of electromagnetic valve, and air intake valve is closed, the recoil simulator of buzzer and indicator lamp one class sends and reports to the police or index signal simultaneously, and food in the pot for cooking rice or water etc. are burned at this moment.The timing knob of timer and the manual knob of air intake valve can adopt linkage manner, promptly open air intake valve when setting timer time.Sound-controlled apparatus can adopt known audio-switch, and its gas whistle can be adopted and can be sent the gas whistle of specifying the sound, and the sound that sends as the commercially available audio-switch gas whistle or pressure cooker safety valve etc. are to avoid the interference of other sound.

Make according to the application's object, by known sound-controlled apparatus, timer, servo and air intake valve or magnetic valve, and the signalling alarm equipment of buzzer and indicator lamp one class, the common timing automatic valve of forming of acoustic control, combustion gas or fuel oil pot for cooking rice are play a part to close automatically on time, make have steaming, boil, stew, boil in a covered pot over a slow fire, multi-functional combustion gas or fuel oil pot for cooking rice economy easy to use, safe such as pot.
