Description
Technical field
The present invention relates to a kind of household gas range, more particularly to a kind of burner for household gas range.
Background technology
In household gas range, generally using the burner of Venturi tube injection air form, traditional Venturi tube is limited by
Structure limitation, its processing is not easy very much；In use, gas nozzle can stretch into the oral area of induction tunnel so that detection spray
At mouth to valve body during the air-tightness of gas circuit, using leak detector operating difficulties, therefore the means detected with naked light are usually taken, and naked light
Examine there is also limitation, it is less than normal but leakage of more than relevant criterion may can't check for air leakage, if there is gas leakage
Phenomenon and do not find, product, which comes into the market, will cause very big potential safety hazard.
The content of the invention
The purpose of the present invention is to overcome that above-mentioned not enough there is provided a kind of burner for facilitating nozzle leading portion air-leakage test.
The present invention is achieved through the following technical solutions.A kind of gas stove burner, including induction tunnel, furnace head base,
There is fixed nozzle burner, induction tunnel front end and is provided with the induced-draft plate in air inducing hole, and the air-breathing of the induction tunnel shrinks the pipe of pipeline section
Wall opening, its oral area has movable injection lid to be tightly connected, and the movable injection cap wall is the extension of injection inside pipe wall, protects
Hold injection inside pipe wall global shape.
Above-mentioned gas stove burner, the movable induction tunnel cover gab of induced-draft plate correspondence, part induced-draft plate and activity
Injection lid links together.
The connection faying face of above-mentioned gas stove burner, the movable injection lid and induction tunnel is stairstepping.
Above-mentioned gas stove burner, the escape pipe of the furnace head base has axial step, and burner is placed on furnace head base
Side is simultaneously pressed together on the step by air inlet pipe.
The gas stove burner of the present invention, pipeline section opening is shunk and equipped with corresponding movable injection in the air-breathing of induction tunnel
Lid, gas circuit and nozzle are affixed on the induced-draft plate of induction tunnel, detection nozzle to valve body at gas circuit air-tightness constantly,
First opening activity injection lid, fixture is entered in induction tunnel and blocks nozzle（It is difficult to block nozzle by fixture that traditional induction tunnel, which is,
Detect amount of leakage）, detect that the amount of leakage before nozzle, detection cover movable injection lid after finishing, detect easy to operate.
Pipeline section is shunk due to the air-breathing of induction tunnel and is in negative pressuren zone, therefore combustion gas will not be let out by the interface of movable injection lid and induction tunnel
Reveal in air, will not leave behind potential safety hazard, further, the interface of movable injection lid and induction tunnel, which is used, to be tightly connected,
There is cascaded surface to increase local resistance and the on-way resistance of inside and outside vent flow on its faying face, effectively prevent extraneous air to pass through
Contact surface enters induction tunnel, only allows from air-vent air inlet, beneficial to integrally-regulated primary air amount.
The induced-draft plate of former traditional butterfly piece type, because structure is limited, is reassembled with induction tunnel after needing respective machine-shaping
Together, by induced-draft plate opening, integral die-cast can be realized by part induced-draft plate is linked together with movable injection lid, while
The integral die-cast of induction tunnel and induced-draft plate can be realized, process for machining and assembly technology is optimized, it is cost-effective.
Burner directly can be coordinated with furnace head base by entering pipe hold gap, and a step is provided with furnace head base, combustion gas leakage is increased
The local resistance of gas, so as to ensure its security used.
Induction tunnel, movable injection lid, furnace head base, burner are made of die casting aluminium entirely in the present invention, and assembly precision is high, table
Face is smooth, primary air injection volume is increased, beneficial to burning.
Brief description of the drawings
Fig. 1 is the structural representation of the gas stove burner of the present invention.
Fig. 2 is that the section view of main fiery system in Fig. 1 just reaches schematic diagram.
Embodiment
The gas stove burner of the present invention is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of gas stove burner, including main fiery system and central flame system, induction tunnel and furnace head base
It is fixed in a fixed plate 7, the induced-draft plate of induction tunnel offers air inducing hole, and gas nozzle 8, compression spring 9, air flap 10 are successively
On induced-draft plate 1, the air-breathing contraction section of induction tunnel is stretched into the front end of gas nozzle 7.Main fiery system include main fiery induced-draft plate 1,
Air-breathing contraction section on main fiery induction tunnel 2, main stove headstock 3, main stove first 4, main fiery induction tunnel 2 from separating up and down, and main fire draws
The top of wind piece 1 is connected as a single entity with the movable injection lid 5 of main fire, is matched with 2 on main fiery induction tunnel, is fixed using screw 6；Main fire draws
The bottom of wind piece 1, the latter half air-breathing collapsible tube and mixation tube section, diffusion pipeline section constitute main fiery induction tunnel 2, and the main fiery activity is drawn
The extension that the inwall of lid 5 is the main inwall of fiery induction tunnel 2 is penetrated, injection inside pipe wall global shape is kept, as shown in Figure 2；Received in air-breathing
There is cascaded surface on the movable faying face of injection lid 5 of draw Duan Yuzhu fire, increase the local resistance of inside and outside vent flow and hindered along journey
Power, effectively prevents extraneous air to enter main fiery induction tunnel 2 by contact surface, only allows from the air inlet of end face induced-draft plate 1, again
Because air-breathing contraction section is negative pressuren zone, therefore combustion gas will not be leaked to air by the main movable injection lid 5 of fire and main fiery induction tunnel 2
In, so as to be beneficial to integrally-regulated primary air amount and air tight, while the movable injection lid 5 of main fire will biography with main fiery induction tunnel 2
1 point of the induced-draft plate of the butterfly piece type of system is two parts combining form, beneficial to die cast.Gas circuit and gas nozzle 8 are connected solid
Determine onto main fiery induction tunnel 2, gas nozzle 8 is blocked by fixture（It is difficult to block nozzle detection by fixture to let out that traditional induction tunnel, which is,
Dew amount）, detect that the amount of leakage before nozzle, detection cover the movable injection lid 5 of main fire, lock-screw 6 after finishing.
Main stove first 4 can directly with main stove first 3 coordinated by air inlet interporal lacuna, on main stove headstock 3 be provided with one
Step, main stove first 4 is placed on the main top of stove headstock 3 and is pressed together on by air inlet pipe on the step, increases gas leakage
Local resistance, so as to ensure its security used, have a socket in its opposite side, lock has the screw of copper post in the socket,
Axially position, it is ensured that cleaning cooktop and burner can be disassembled at any time.
Central flame system is consistent with above-mentioned main fiery system architecture.
