Description

Upper air inlet burner

Technical Field

The utility model relates to the field of gas stoves, in particular to an upper gas inlet burner.

Background

When the gas stove works, gas enters the stove from the gas inlet pipe, enters the stove head through adjustment of a user through the knob, the stove head is provided with a distributor, and the gas is sprayed out through fire holes of the distributor and is simultaneously ignited by an ignition device to form flame; during cooking, the temperature is too high due to the fact that the pot bottom is too close to the furnace end, a gas pipeline is blocked, and the like, and the tempering phenomenon is caused, so that the safety problem is caused.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an upper air inlet burner can effectively prevent the tempering, improves the security performance of gas-cooker.

In order to achieve the above purpose, the technical solution of the present invention is as follows:

the utility model provides an go up gas burner, includes the furnace end to and the distributor of setting on the furnace end, the furnace end is provided with the main jet hole, and the main jet hole is provided with a plurality of times fumaroles all around, leave the clearance between time fumarole and the distributor.

The burner and the distributor are separated by a certain distance, so that flame can not be tempered along the air inlet pipeline, and high-temperature tempering can also be prevented.

Further, the distributor includes interior fire lid seat and outer fire lid seat, and interior fire lid seat is installed in the main jet-propelled hole department of furnace end, and outer fire lid seat is provided with a plurality of bleed pipes, the bleed pipe corresponds the inferior fumarole of furnace end, and leaves the clearance between bleed pipe and the inferior fumarole.

Further, a clamping ring is arranged on the pipe body of the main air injection hole, a plurality of grooves are formed in the side edge of the clamping ring, and the inner fire cover seat is buckled on the clamping ring.

In order to make the secondary air injection hole correspond to the air vent of the distributor, the main air injection hole is provided with a snap ring, so that the air holes of the two air injection holes correspond.

Furthermore, the gas guide pipe is arranged beside the air outlet hole of the inner fire cover seat and is provided with a blocking piece, and the blocking piece enables the gas coming out of the gas guide pipe to diffuse to the two sides of the air outlet hole.

The existence of the blocking piece can enable fuel gas to be diffused in the fire divider instead of being directly sprayed out from the combustion holes of the fire divider, so that flame can be uniformly combusted, and the condition that people are injured due to the spraying of the flame can be prevented.

Further, the blocking piece comprises a side flange arranged beside the air outlet hole and an upper flange arranged above the air outlet hole.

This embodiment is further preferable to the above embodiment.

Furthermore, a plurality of upper flanges are connected through a ring, and the ring is sleeved on the outer fire cover seat.

Further, the number of the secondary air injection holes is 1-4.

According to the size of the furnace end of the gas stove, the number of the secondary air injection holes can be reasonably designed, so that the number of the air guide pipes can be correspondingly adjusted.

From the perspective of part processing, the side flanges and the upper flanges of the blocking piece are more conveniently processed separately.

After the scheme is adopted, compared with the prior art, the utility model, have following advantage:

through redesign to furnace end and distributor, very big reduction the phenomenon of tempering when the gas-cooker burns to improve the security of gas-cooker, and considered the utilization of gas and the distribution when burning simultaneously, improved the utilization ratio to gas.

description of the reference symbols

The burner comprises a burner head 1, main air injection holes 11, secondary air injection holes 12, a clamping ring 13, a distributor 2, an inner fire cover seat 21, an inner fire cover 22, an outer fire cover seat 23, an air guide pipe 231, an outer fire cover 24, a side flange 3, an upper flange 4 and an air outlet hole 5.

Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments.

As shown in the figure, an go up gas burner, includes furnace end 1 to and set up distributor 2 on furnace end 1, wherein, distributor 2 divide into inner circle and outer lane, comprises respective interior fire lid seat 21 and interior fire lid 22, outer fire lid seat 23 and outer fire lid 24, all is provided with the round burner orifice on interior fire lid 22 and the outer fire lid 24.

Wherein, the main jet orifice 11 of furnace end 1 corresponds interior fire cover seat 21, and the secondary jet orifice 12 of furnace end 1 corresponds outer fire cover seat 23, and interior fire cover seat 21 is connected with the body of main jet orifice 11, is provided with snap ring 13 on the body of main jet orifice 11, and a plurality of recesses have been seted up to snap ring 13 side, and interior fire cover seat 21 lock is on snap ring 13 to make secondary jet orifice 12 corresponding with the air vent of outer fire cover seat 23 below.

The bleed ducts 231 are formed to extend from below the outer fire cover base 23 so that the air vents at the ends of the bleed ducts 231 are spaced closer to the secondary air ports 12, but with a gap therebetween, thereby preventing the flames from burning directly along the secondary air ports 12 to form flashback, and as shown in the drawing, in this embodiment, three of the bleed ducts are caused to correspond to respective ones of the secondary air ports 12 and are uniformly distributed.

The bleed pipe 231 is located the other venthole 5 that is provided with of interior fire cover seat 21 and blocks, blocks the gas that makes bleed pipe 231 come out and to 5 both sides diffusion of venthole, and the existence that blocks can make the gas diffuse in distributor 2, rather than spout in the direct burner port from distributor 2, can be so that the flame combustion is even, can prevent again that the flame blowout from hurting the people.

This stop piece is including setting up side flange 3 by venthole 5 to and set up last flange 4 in venthole 5 top, accessible ring connection between the three flange 4 of going up, and cup joint the ring on outer fire lid seat 23, it is more convenient with the separate processing of side flange 3 and last flange 4 of stopping like this.

The aforesaid is only the embodiment of the utility model discloses, all simultaneously the utility model discloses in related words such as "upper and lower, left and right, centre" only do the reference usefulness, not absolutely restricted, all utilize the utility model discloses carry out insubstantial change, all shall belong to the act of infringing the protection scope of the utility model.
