Abstract

The utility model provides a weighing gas stove which can prevent flame from leaping up along the pot wall, automatically reduce fire when the pot is almost dry or even overflows until the gas valve is closed, and give alarms. The weighing gas stove comprises fire-blocking rings arranged on the disc-type gas stove pot supports and used for preventing the flame from leaping up along the pot wall, three groups of weighing press plates, tension springs, adjusting bolts, connecting rods, and press-open type gas valves and press-on type travel switches connected with the weighing press plates through drawbars. When the weight of the pot is gradually reduced to below the carrying load of the weighing press plates, the weighing press plates raise up slowly to allow the press-on type travel switches to be closed gradually and give alarm. Three water-receiving tanks are connected with pull-close type gas valves and the press-on type travel switches through press rods; and when the water levels of the water-receiving tanks reach the predetermined overflow limit, the gas valves are gradually closed while giving alarm. The various press-open type gas valves and the pull-close type gas valves are connected in series with ignition switches. The various press-on type travel switches are in electrically connected in parallel with one another and electrically connected in series with the ignition switches, an alarm and a battery. When the ignition switches are closed, the power supply of the alarm is cut off, thereby achieving safety and energy-saving effect.

Description

The gas-cooker of weighing

Technical field

The utility model relates to a kind ofly can prevent that flare is excessive, especially at pot and the gas-cooker that can the automatic self-closing gas valve when dryouting soon pot of overflowing.

Background technology

At present, known gas-cooker is to be configured to by the kitchen range top and the kitchen range that supports pot, and the combustion gas flare can be leapt up along a pot limit, Hu Bianshang in use, and waste combustion gas and heat energy can put out a fire by water when overflowing pot, is easy to cause fire when dryouting pot.

Summary of the invention

Flare can be along leaping up on the pot limit in use in order to overcome existing gas-cooker, waste combustion gas and heat energy, when overflowing pot, can put out a fire by water, dryout a pot deficiency that causes fire easily, the utility model provides a kind of energy-saving safety gas-cooker of weighing, this gas-cooker can not only stop the combustion gas flare to be leapt up on excessive, and can overflow pot and dryout pot soon in cut off burnt gas valve and send alarm signal.

What its technical problem that solves the utility model adopted is: be provided with the multilayer fire trapping ring on the gas-cooker frame, and three groups of compressing tablets of weighing that increase successively with fire trapping ring evenly distribute, be connected with the extension spring that pulling force from inside to outside strengthens successively, regulation cock can integrally-regulatedly weigh, in, the outer ring compressing tablet of weighing links to each other by connecting rod, the inner ring compressing tablet of weighing is connected with driving lever, the pressure general formula travel switch that connects pressing type burnt gas valve and pull bar place by pull bar, water receiving tank under the taper storehouse, draw the pressure general formula travel switch at pass formula burnt gas valve and depression bar place by the depression bar connection, counterweight is regulated tank water receiving amount, each pressing type burnt gas valve and draw pass formula burnt gas valve for being connected in series, each presses in parallel electrical connection the between the general formula travel switch, with ignition switch, alarm and battery are electrically connected in series, normal pressing type burnt gas valve down is for closing, the pressure general formula travel switch at pull bar place is for connecting, when the weight of pot during less than the weighing of the compressing tablet of weighing, the pressing type burnt gas valve drives by pull bar and closes burnt gas valve gradually, press the general formula travel switch to recover to connect power supply simultaneously, alarm rings, water receiving tank draws pass formula burnt gas valve and presses the general formula travel switch by the depression bar connection, normal drop-down pass formula burnt gas valve is open-minded, the pressure general formula travel switch at depression bar place is for disconnecting, the water that overflows when pot converges in the water receiving tank, make the whole whereabouts of tank, drive to close by depression bar and draw pass formula burnt gas valve, connect and press general formula travel switch power supply to send alarm signal.

The beneficial effects of the utility model are: save combustion gas, heat is concentrated indiffusion, and effective multiple protective when pot reaches the certain light weight and the pot that overflows is closed gradually until the disconnection burnt gas valve, and the prompting that gives the alarm, the guarantee energy-saving safety.
