Description

Gas appliance

Technical field

For example the present invention relates to the Gas appliance of the gas kitchen ranges that can control by the action of combustion gas burners such as the fuel gas supply of the formula contact witch subtend combustion gas burner that automatically resets and gas flow adjusting thereof etc.

Background technology

This gas kitchen ranges is known for example special fair 7-94890 communique of Japan Patent.This gas kitchen ranges can be divided in the kitchen range body, be arranged to be positioned at place in front of the top board opening 2 Ben Shengshi cooker burners and be arranged at two kinds of ceramic board-like grid burners on the grid.The mixing tube of each burner respectively be that the branched pipe of 1 Gas Pipe branch of open and close valve is connected from being provided with magnetic valve.

In each branched pipe, be provided with flow control valve from usefulness to the gas flow of each burner of kitchen range and grid that regulate.This flow control valve for example has the driving body of the area of passage increase and decrease usefulness of fuel gas path, and this driving body is driven by the motor of stepper motor etc.

Wherein, the gas kitchen ranges that is provided with respectively a plurality of combustion gas burners that are connected with branched pipe from 1 Gas Pipe branch, in order individually to use each burner, the combustion gas of must each burner of subtend supplying with is controlled.

For this reason, in the above-mentioned structure, flow control valve has the apolipsis function.And, each burner of kitchen range and grid catch fire and the control of action such as firepower adjusting is that contact witch by the formula that automatically resets on the guidance panel that is arranged at kitchen range body front carries out.

In case by pressing the igniting indication that the operation contact witch sends burner, then by the motor-driven driving body, flow control valve travels to out valve position from closing valve position, the valve opening solenoid valve is lighted a fire simultaneously.In this occasion, reliably catch fire in order to make the combustion gas burner, Flux Valve Control must be become make the combustion gas burner to place the combustion gas of the gas flow of strong fire to flow into.And the gas flow of combustion gas is by regulating the contact witch of usefulness, by the motor-driven driving body aperture area of fuel gas path is changed to carry out by pressing the operation firepower.

Yet, in this structure, for example use the occasion of 2 cooker burners at the same time, during a certain side's cooker burner quench, because of magnetic valve can not close valve, so must close valve with the cooker burner corresponding flow control valve of wanting quench.In this occasion, by motor the valve position that closes that driving body travels to flow control valve is needed time several seconds, so exist quench to need the problem of spended time.

In case when the cooker burner behind the quench is wanted to light a fire, by motor driving body is urged to and makes the combustion gas burner, need the problem of spended time so also produced to light a fire for the ignition location that the combustion gas of the gas flow of strong fire flows into again.

And, when lighting a fire, for the valve action need of opening of driving valve operation and flow control valve that carries out magnetic valve simultaneously has big electric current at the initial stage of each burner.In this occasion, for example must strengthen transformer capacity, cause cost to increase.

Summary of the invention

For this reason, in view of the above problems, the object of the present invention is to provide a kind of igniting quench that can carry out the combustion gas burner fast, and can reduce the Gas appliance of current drain.

Adopt the present invention, in case carry out the igniting indication of combustion gas burner by pressing the operation contact witch, then each open and close valve of the 1st and the 2nd is driven valve respectively.In this occasion,, can will not close valve position so when combustion gas last time burner quench, do not need that flow regulator is travelled to the fuel gas supply blocking of each burner by the 2nd open and close valve owing in branched pipe, be provided with the 2nd open and close valve.Thus, when each open and close valve of the 1st and the 2nd is driven valve, can make combustion gas flow into the combustion gas burner immediately and carry out ignition operation.

And, for example when the occasion of using 2 combustion gas burners, when either party's combustion gas burner quench if the 2nd open and close valve is closed valve, but this combustion gas burner quench then.In this occasion, compare with the structure that by the motor-driven driving body flow regulator is travelled to close valve position to carry out quench and can carry out quench fast.

Again, in case when the combustion gas burner behind the quench is wanted to light a fire, because of flow regulator is in the position that the fluid of combustion gas does not interdict, so in case the 2nd open and close valve is driven valve, then combustion gas is supplied with and lighted a fire to the combustion gas burner immediately.Thus, and move to the structure that ignition location lights a fire and compare from closing valve position, its igniting need not spended time.

In addition, described flow regulator can not be provided with the apolipsis function.Thus, because of flow control valve itself does not need sealing highly, so can reduce manufacturing cost.

In sum, adopt Gas appliance of the present invention, not only can carry out the igniting quench of combustion gas burner apace, and can obtain to reduce the effect of current drain.
