Abstract

The utility model relates to an automatic controller for a gas burner. An open and close valve for a gas circuit is added on a gas inlet pipe of an original gas burner; one or a plurality of bearing heads are arranged on a supporting frame for heated objects of the burner; the opening and the closing of the open and close valve for the gas circuit and the switching of an ignitor are controlled by a pressure driving mode. The utility model with simple structure can ignite and the extinguish a burner for a gas burner by making use of the placing and the pullout of the heated objects from the burner, and other actions are not used, so the gas saving effect can be obtained.

Description

The gas stove automaton

The utility model relates to the control of gas stove, relates to the switching and the igniting automaton of gas stove gas circuit specifically.

China town dweller and part rural area now have been extensive use of various fuel gas and have done fuel, the gas stove of selling on the market is also of a great variety, the gas circuit of cooking stove and the control of igniting mostly need manually substep operation, placing (end from) heating object and igniting (or flame-out) on cooking stove can not finish synchronously, to constantly light a fire or be flame-out in the interval of particularly cooking multiple food, when busy, often forget and close the cause of fire and waste energy, leave for toward becoming unsafe hidden danger.Though being 95234829.2 utility model patent, the patent No. of now having announced solved the problem of gas stove regular job preferably, but because its structure is complicated, thereby in implementation process, can make product cost too high, certain difficulty is arranged on applying.

The purpose of this utility model just provides a kind of gas stove automaton simple in structure, easy to use, it can utilize the placement of heating object easily or withdraw burner, and without other action, just can realize the switching of gas stove gas circuit and the unlatching of igniter, to reach the effect of saving combustion gas.

In order to finish the above object, the utility model adopts following solution, on the main inlet control valve external admission pipe of original gas stove, set up a gas circuit open and close valve, being heated of burner place be equipped with on the support can upper and lower motion pressure bearing head, and link by Pressure Actuated Device and gas circuit open and close valve and igniter, promptly when pressure bearing head was depressed, the gas circuit of gas circuit open and close valve was by open-minded, simultaneously the Reciprocative switch of igniter is opened and struck sparks the ignition combustion device; When pressure bearing head lifted, open and close valve was closed, and fire extinguishes naturally.During use, open the main inlet control valve of cooking stove earlier, when heating objects such as pot are placed on the burner place support, pressure bearing head is oppressed under the gravity effect moves downward, by the push rod on the Pressure Actuated Device promotion open and close valve, the sealing-plug that stops up gas circuit in the open and close valve is open, gas circuit is open-minded, combustion gas enters burner through main inlet control valve, and Pressure Actuated Device is when promoting push rod, simultaneously the switch of opening point firearm, make igniter sparking and light the combustion gas of coming out from burner opening, regulate flame size as need, can adjust main inlet control valve, in the hope of reaching stable flame face.When heating object end during from burner, the compressing weight on pressure bearing head disappears, and open and close valve is under himself spring action, and sealing-plug is trapped on the gas circuit, and the open and close valve gas circuit is closed, and burner extinguishes flame because of no fuel gas supply automatically.With this sequentially-operating, if on the heating object end or end just can reach from the burner opening support and light or extinguish cooking stove, realized the purpose of automatic control flame thus.So also just reduce the no purpose burning of gas stove, thereby reached the effect of good energy savings, realized the bivalve control of combustion gas gas circuit simultaneously, increased safety coefficient.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A-A structure for amplifying cutaway view of gas circuit open and close valve.

Among the figure, 1 is main inlet control valve, and 2 is the gas circuit open and close valve, 3 is pressure bearing head, and 4 is Pressure Actuated Device, and 5 is igniter, 6 is burner, and 7 is air inlet pipe (gas circuit), and 11 is the tolerance adjusting knob of main inlet control valve, 21 is push rod, and 22 is the gas circuit sealing-plug, and 23 is the gas circuit mouth, 24 is spring, and 25 is sealing gasket, and 26 are the sealing spring, 27 is push-rod handle, and 28 is the open and close valve upper press cover, and 29 is the open and close valve base, 41 is drive link, and 42 is the drive link gathering sill, and 43 are the transmission feather key, 44 is the drive link fixator, 45 is push arm, and 46 is fixed support, and 47 is rebound spring, 51 is ignition switch, and 52 is the ignition burner pipe.

Pressure Actuated Device 4 shown in Figure 1 is made up of drive link 41, push arm 45, fixed support 46, one end of drive link 41 should be fixed on the fixed support 46, for drive link 41 and push arm 45 not being departed from when pressure bearing head 3 falls and twisting, on support 46, be provided with gathering sill 42, making feather key 43 on the drive link 41 do with fixator 44 in groove 42 is the circular motion of center of circle fulcrum, and promptly can to do with transmission fixator 44 with moving up and down of pressure bearing head 3 be the pressure transmission of fulcrum for drive link 41 and push arm 45.In order to guarantee pressure bearing head 3 rapid return when the no pressure, should be provided with one or several rebound springs 47 for 41 times at drive link, the rebound spring of present embodiment be located at gathering sill 42 below.Ignition switch 51 is the Reciprocative switches that are fixed on the fixed support 46 among Fig. 1, and Reciprocative switch 51 contacts with the movable position drive link 41 or the push arm 45 of Pressure Actuated Device 4, presses switching by the motion of transmission device 4.The igniter of present embodiment is selected commercially available ignition for use, because of being that prior art this paper does not do detailed description.

Figure 2 shows that the structure cutaway view of gas circuit open and close valve 2, it is by push rod 21, sealing-plug 22, gas circuit spring 24, sealing gasket 25, sealing top spring 26, upper press cover 28, base 29 compositions such as grade.When pressure bearing head 3 falls, promote push rod 21 by Pressure Actuated Device 4, force spring 24 compressions, thereby make sealing gasket 22 leave air inlet pipe gas circuit 23, then gas circuit is unimpeded, and combustible gas can pass through smoothly, otherwise also anti-.
