Abstract

The invention relates to an automatic gas stove, comprising a shell 1, a burning disc 2, a cooking utensil supporting bracket 3, an electric weight controller 4, an electric flameout controller 5, an electric igniter 6 and an electromagnetic pipe valve 7. The cooking utensil supporting bracket 3 is provided with three supporting legs and is supported by a supporting bracket plate 8 which is fixed on the bottom plate of the shell 1; a pressure sensor 9 is arranged below one supporting leg; an elastic switch 10 is arranged below another supporting leg; two electrodes 11 and 12 which are fixed beside the burning disc 2 and are insulated with the burning disc 2 form a flame detector of the electric flameout controller 5; an electric weight displaying disc and a control key panel are arranged in the left front of the shell 1; and the electromagnetic pipe valve 7 is controlled by the electric weight controller 4, the electric flameout controller 5 and the elastic switch 10 which are connected in series. The automatic gas stove is controlled automatically according to the change of the weight of the heated cooking utensil, without being controlled manually, thereby being protected against dry heating, flameout and waste, and the automatic gas stove is convenient to use and simple in structure.

Description

Automatic gas stove

What the present invention relates to is gas range device.

In existing technology, though gas-cooker is of a great variety, function is different, its characteristics are respectively arranged, but all can not control automatically, cause some such things usually take place in the life the cooker that it heated, originally wanted to burn a kettle boiling water, point goes busy other thing after catching fire again, treats that flash upon makes a return journey when seeing, finds that water in the kettle has soon evaporated and do not had; Originally wanted to stew a pot liquor, the result remembers after a while and making a return journey when seeing that the soup in the pot has soon dryouied, and steam one pot of steamed bun, and the water in the pot has been put many just wastes combustion gas, puts to have lacked and be afraid of and dryouied pot that the existing gas-cooker of these problems all can't solve not enough.

I am at present gas-cooker technology above shortcomings, have invented a kind of automatic gas stove, according to the variation of weight of heated cooker it is controlled automatically, boil water, stew, steamed sweet bun etc. need not manually to keep an eye on, and are easy to use, energy-conservation.

The present invention includes: housing 1, tray for combustion 2, cooker carriage 3, electronics weight controller 4, the electronics controller 5 that stops burning, ignition 6, pipeline magnetic valve 7 constitutes, it is characterized in that, cooker carriage 3 is provided with 3 legs, and by carrier frame plate 8 supports that are fixed on gas-cooker housing 1 base plate, the pressure sensor 9 of electronics weight controller 4 is equipped with in one underfooting of cooker carriage 3, another props up the elastic switch 10 that ignition is housed the underfooting, the sensor of controller 5 of stopping burning is by two electrodes 11 that are fixed on the tray for combustion 2,12 form, electrode 11,12 each other at a distance of about 1 millimeter, and with tray for combustion 2 insulation, electronics display panel and control the left front that the setting of key panel is installed in housing 1, magnetic valve 7 is installed in the gas pipeline porch, right side of tray for combustion 2,13 is the probe of ignition 6, provides power supply by civil power.

When cooker is placed on the cooker carriage 3, because of the gravity effect, cooker carriage 3 presses down, and pressure sensor 9 is given electronics weight controller 4 with feedback information, and the electronics display panel on the panel demonstrates the weight of cooker immediately, and conducting electronic valve 7 is put into combustion gas, meanwhile, elastic switch 10 closures of the another underfooting of cooker carriage 3, ignition 6 igniting, gas-cooker enters duty, electronics weight controller 4 and electronics controller 5, the elastic switch 10 series connection control magnetic valves 7 that stop burning.If will control automatically, only need to set a gravimetric value and get final product according to actual conditions to cooker.Such as the weight of wanting boiled water flask is 4500g, and our weight of choosing setting is that 4490g gets final product so, when 10g water is fallen in the water explosive evaporation in the kettle, electronics weight controller 4 cuts out the power supply of magnetic valve 7 automatically, cut off combustion gas, stop heating, need not manually to nurse constantly.In steamed sweet bun, before not adding water in the pot, be placed on and demonstrate its weight on the gas-cooker, as 8000g, and then add entry, as 1000g, then be set in 8500g and get final product, when the gross weight of steamer reduces to 8500g, promptly close burning things which may cause a fire disaster, need not artificial nurse, both convenient, prevent not only dry combustion method but also energy-conservation.

The electronics of the present invention controller 5 that stops burning promptly enters the conducting duty after gas-cooker is lighted, because the air between the electrode 11,12 is by flame ionization and conducting, in case stop burning, then the resistance between electrode 11 and the electrode 12 increases immediately, the electronics controller 5 that stops burning is cut the power supply of magnetic valve 7 immediately, turn-offs combustion gas.

There is not setting weight or under greater than the weight situation of setting, ignition when cooker is placed on the cooker carriage 3, when cooker left, elastic switch 10 disconnected, and magnetic valve 7 cuts out, and gas-cooker stops burning.The present invention is simple in structure, and is easy to use, and promptly safety is energy-conservation again.

Accompanying drawing is an embodiment of the invention structural representation, see shown in the accompanying drawing, automatic gas stove of the present invention comprises: housing (1), tray for combustion (2), cooker carriage (3), electronics weight controller (4), the electronics control (5) of stopping burning, ignition (6), pipeline magnetic valve (7) constitutes, it is characterized in that: cooker carriage (3) is only established three legs, and by carrier frame plate (8) support that is fixed on housing (1) base plate, the pressure sensor (9) of electronics weight controller (4) is equipped with in one underfooting of cooker carriage (3), another props up the elastic switch (10) that the underfooting is housed by ignition (6), stop burning the sensor of controller (5) by electrode (11), (12) form, (13) be the probe of ignition, electronics display panel and control the left front that the setting of key panel is installed in housing (1), magnetic valve (7) is installed in the right side of tray for combustion (2), system power supply is provided by civil power, electronics weight controller (4) and the electronics controller (5) that stops burning, elastic switch (10) series connection control magnetic valve (7).
