Abstract
A switch valve body of a gas-fired cassette-type furnace is applicable to an infrared cassette-type furnace. Based on the former valve body, a frequently close ignition switch is added. An igniting and gas-firing passage is switched on by lifting-off a mandril of the ignition switch. The ignition spark ignites the gas, which is sprayed from an ignition nozzle to form a taking-fire flame, and accordingly to ignite an infrared burning device. The valve body realizes the convenient ignition of the infrared cassette-type furnace and has the advantages of reliable ignition and low cost.
Description
Technical field:
The utility model relates to the improvement of combustion gas cassette cooker, especially the improvement of cassette cooker switch valve body.
Background technology:
As everyone knows, household gas utensils all are to adopt piezo-electric ignition and pulsed electron igniting dual mode basically, and an urgent demand has the go out barbecue and the cooking gas appliance of superior performance on the market, and cassette cooker just arises at the historic moment.Yet, because the combustion gas cassette cooker wind resistance of this normal atmospheric formula is poor, the use when not fitting into outdoor big wind speed, infrared burner has efficient energy-saving, sufficient combustion, advantage that wind resistance is good, and the utmost point is adapted to outdoor application.Cassette cooker valve body on the market all adopts the sparking mode of direct pilot spark in burner now.The advantage of this sparking mode is that cost is low, easy for installation; It has the defective of following aspect:
(1) because it is to adopt the piezoelectric ceramics igniting, single pilot spark directly acts on the burner and lights a fire, the igniting weak effect, and the rate of catching fire is low.
(2) it can only be used for the cassette cooker of atmospheric burning type mode; When adopting infrared burner, just can not light a fire, can't normally use.
Solve the ignition problem of infrared ray cassette cooker, be a big technical barrier of the high-performance cassette stove design of outdoor application always.
Summary of the invention:
The purpose of this utility model is by improving the ignition structure of cassette cooker switch valve body, the infrared ray cassette cooker to be lighted a fire reliably.
The utility model is achieved through the following technical solutions:
A kind of combustion gas cassette cooker switch valve body, form by valve chest (1), safety device switch (2), escape pipe nozzle assembly (3), air inlet (4), rotary switch (5), epithelium (6), pressure stability device (7), be connected with an ignition switch (8) on the valve chest (1), be connected with Gas Pipe (9) on the ignition switch (8), there is ignition burner (10) Gas Pipe (9) outer end, and there is the support (11) of igniting of lighting a fire the front portion of ignition burner (10); One big cavity (12) is arranged on the ignition switch (8), between air cavity (13) that is connected with air inlet (4) in the valve body and big cavity (12) blast tube (14) is arranged; A sealing push rod (15) is arranged on the ignition switch (8), there is little cavity (16) big cavity (12) below in ignition switch (8), big cavity (12) links to each other with little cavity (16), sealing push rod (15) places in the big cavity (12), big cavity (12) and little cavity (16) can be separated, and extend to outside the cavity of big cavity (12), the outer end of sealing push rod (15) is provided with spring (17), makes sealing push rod (15) be in normally closed under normal conditions and big cavity (12) and little cavity (16) are separated; Gas Pipe (9) is communicated with little cavity (16), rotary switch (5) is gone up outer end (18) and will be sealed push rod (15) jack-up when rotary switch (5) rotating operation, big cavity (12) on the ignition switch (8) is communicated with little cavity (16), combustion gas is by air inlet (4), enter air cavity (13), through blast tube (14), enter big cavity (12), by little cavity (16) after Gas Pipe (9) arrives ignition burner (10), produce pilot spark simultaneously and light pyrophoric flame, meanwhile, escape pipe nozzle assembly (3) is connected combustion gas, and pyrophoric flame is lighted burner.Big cavity (12) on the ignition switch (8) is sealed separation with little cavity (16) when sealing push rod (15) is not backed down by external force.Rotary switch (5) can adopt the screw-type structure, also can adopt the cock-type structure.Like this, when using the infrared ray cassette cooker, the outer end (5) of valve body rotary switch (5) just can be with sealing push rod (15) jack-up, cut-in point internal heat source channels, and pilot spark is lighted pyrophoric flame, and pyrophoric flame is lighted infrared burner.After lighting infrared burner, unclamp rotary switch (5), because the spring force effect of spring (17), make big cavity (12) and little cavity (16) parting seal, can cut off the blast tube of ignition burner (10), the igniting pyrophoric flame extinguishes, and realizes ignition operation easily.
That advantage of the present utility model is to light a fire is effective, the rate of catching fire height, cost are low, can adapt to the use of infrared burner cassette cooker.

Specific embodiment:
Embodiment 1:
A kind of combustion gas cassette cooker switch valve body, form by valve chest (1), safety device switch (2), escape pipe nozzle assembly (3), air inlet (4), rotary switch (5), epithelium (6), pressure stability device (7), be connected with an ignition switch (8) on the valve chest (1), be connected with Gas Pipe (9) on the ignition switch (8), there is ignition burner (10) Gas Pipe (9) outer end, and there is the support (11) of igniting of lighting a fire the front portion of ignition burner (10); One big cavity (12) is arranged on the ignition switch (8), between air cavity (13) that is connected with air inlet (4) in the valve body and big cavity (12) blast tube (14) is arranged; A sealing push rod (15) is arranged on the ignition switch (8), there is little cavity (16) big cavity (12) below in ignition switch (8), big cavity (12) links to each other with little cavity (16), sealing push rod (15) places in the big cavity (12), big cavity (12) and little cavity (16) can be separated, and extend to outside the shell of big cavity (12), the outer end of sealing push rod (15) is provided with spring (17), makes sealing push rod (15) be in normally closed under normal conditions and big cavity (12) and little cavity (16) are separated; Gas Pipe (9) is communicated with little cavity (16), rotary switch (5) is gone up outer end (18) and will be sealed push rod (15) jack-up when rotary switch (5) rotating operation, big cavity (12) on the ignition switch (8) is communicated with little cavity (16), combustion gas is by air inlet (4), enter air cavity (13), through blast tube (14), enter big cavity (12), by little cavity (16) after Gas Pipe (9) arrives ignition burner (10), produce pilot spark simultaneously and light pyrophoric flame, meanwhile, escape pipe nozzle assembly (3) is connected combustion gas, and pyrophoric flame is lighted burner.Big cavity (12) on the ignition switch (8) is sealed separation with little cavity (16) when sealing push rod (15) is not backed down by external force.Rotary switch (5) is the screw-type structure.Like this, when using the infrared ray cassette cooker, the outer end (5) of valve body rotary switch (5) just can be with sealing push rod (15) jack-up, cut-in point internal heat source channels, and pilot spark is lighted pyrophoric flame, and pyrophoric flame is lighted infrared burner.After lighting infrared burner, unclamp rotary switch (5), because the spring force effect of spring (17), make big cavity (12) and little cavity (16) parting seal, can cut off the blast tube of ignition burner (10), the igniting pyrophoric flame extinguishes, and realizes ignition operation easily.
