Description
Technical field
The invention discloses a kind of burners for gas cooker, belong to gas cooker technical field.
Background technique
Existing gas stove burner can be divided into lower wind inlet type and upper wind inlet type two from the arbitrary way of primary air
Kind structure.Traditional burner for gas stove generally belongs to lower wind inlet type structure, i.e., primary air is from kitchen range inner cavity, inner cavity
Bottom needs to be reserved with the air inlet hole of supplement primary air, and this mode is conducive to the supplement of primary air and reduces kitchen range inner cavity
Temperature, but cupboard door need to there are sufficiently large ventilation hole, open cupboard door when have a certain impact to kitchen range combustion conditions；Especially
It is when being tempered for some reason, it is not easy to be found, the flammable components of kitchen range inner cavity can be burnt out, cause safety hidden
Suffer from, and easily cause spray nozzle clogging or aperture to become smaller containing impurity with the ingredient of combustion gas in gas pipeline, needs to open
Panel could be cleared up, replace nozzle, extremely inconvenient, make troubles to maintenance.Upper wind inlet type burner is introduced from European countries,
That is primary air can be easy to be found being tempered, handled not will cause thing in time from stove table-board
Therefore but due to the difference of Chinese and western cooking method, the requirement to the firepower size of gas cooker is different, upper wind inlet type burner
Thermic load is often less than normal, it is difficult to meet requirement of the compatriots to gas cooker firepower, this is mainly existing upper wind inlet type burner
Ejector pipe limited by structure and manufacture craft, be often designed to shorter straight pipe, the ejector capacity of primary air
Far short of what is expected more than Venturi tube used by traditional lower wind inlet type burner, primary air ratio is smaller, needs a large amount of two
Secondary air supplement ability normal combustion, the calorific intensity of fire hole is low, so this upper inlet wind type burner head diameter is big, thermic load phase
To smaller, the thermal efficiency is low.
Summary of the invention
To solve the above problems, there is heat the purpose of the present invention is to provide a kind of burner for gas cooker
Load is high, firepower is big, the thermal efficiency is high, Yi Genghuan nozzle, it is easy to maintenance, using it is safe the features such as.
In order to achieve the above objectives, solution of the invention is: a kind of burner for gas cooker, including bottom
Seat has main fiery gas outlet pipe on pedestal, has central flame gas outlet pipe in the center of main fiery gas outlet pipe；
There is main fiery ejector pipe, central flame ejector pipe in the base bottom, in the inlet end of main fiery ejector pipe and central flame ejector pipe
Be connected with a upper air inlet chamber, there is main fiery gas inlet pipe, central flame gas inlet pipe in upper air inlet chamber side, main fire combustion gas into
It is intracavitary and draw respectively with the main fiery ejector pipe and central flame that the outlet side of tracheae and central flame gas inlet pipe puts in upper air inlet
The inlet end for penetrating pipe is oppositely arranged in the intracavitary of upper air inlet chamber；It is logical that the outlet side of the main fiery ejector pipe is communicated with a fan-shaped arc
Road, fan-shaped curved channel are communicated with a straight channel, and straight channel is connected to the main fiery gas outlet pipe, the central flame ejector pipe
It is connected to the central flame gas outlet pipe；Tray for combustion, the main fiery gas outlet pipe and burning are also configured on the pedestal
Main blast tube in disk communicates, and central flame gas outlet pipe is communicated with the center blast tube in tray for combustion, the tray for combustion
It is upper to be configured with inner fire cover, outer fire cover.After adopting the above structure, air enters from upper air inlet chamber, and main fiery ejector pipe has been connected to fan
Shape curved channel and straight channel, in a limited space in the opposite length for extending ejector pipe, enhance drawing for primary air
Ability is penetrated, to improve thermic load, the thermal efficiency.The setting of inner fire cover, outer fire cover makes flame distribution more evenly, is conducive to secondary
The supplement of air and burning are abundant；Spray is typically provided in the outlet side of main fiery gas inlet pipe and central flame gas inlet pipe
Mouth can facilitate the work of maintenance personal directly in the intracavitary maintenance of upper air inlet chamber when spray nozzle clogging.
As the further setting of above-metioned scheme: there are two main fiery ejector pipe, the two main fire to draw for the base bottom tool
It is symmetrical as center line using central flame ejector pipe to penetrate pipe, in this way setting make air ejection ability of the present invention is stronger, thermic load more
Greatly, firepower is more violent, burning is more abundant, the thermal efficiency is higher, effect is best.
The outlet end section of the main fiery ejector pipe is intilted inclined-plane, by inclined-plane setting keep combustion gas smooth into
Enter in fan-shaped curved channel, the middle position of the fan-shaped curved channel arcwall face has a deflector, from two main fiery injections
The combustion gas that pipe comes out improves gas circulation efficiency by deflector intersection in straight channel.
The upper air inlet chamber is the unclosed cavity in top, by bottom surface, left side, right side, concave profile and outer arc
Shape face composition；The left side, right side, concave profile and outer arcuate face all have the flange A upwardly extended；On outer arcuate face
Flange A lower than left side, right side, concave profile flange A, in this way setting be convenient for air from the top in outer arcuate face into
Enter；The burning pan bottom be provided with can be combined together with the flange A on left side, right side, concave profile it is convex
Edge B, in this way setting can prevent soup from flowing into the intracavitary of upper air inlet chamber.
The left side of the upper air inlet chamber, right side, the flange A on concave profile are all equipped with chamfering A；The burning
There is the flange B of pan bottom chamfering B, the flange A and the flange B to be docking together by chamfering A and chamfering B, set in this way
Setting can further prevent soup to flow into the intracavitary of upper air inlet chamber.
The left side and right side bottom of the upper air inlet chamber are equipped with air inlet hole, and the setting of air inlet hole can supplement suitable one
Secondary air reduces the temperature of kitchen range inner cavity.
The tray for combustion includes endogenous fire cage and outer fire cover seat, presses ring by 3~5 between endogenous fire cage and outer fire cover seat
The combustion gas interface channel of shape uniform intervals arrangement connects, and auxiliary air compensation is formed between every two adjacent combustion gas interface channel
Hole has among the endogenous fire cage with central flame gas outlet pipe with hole together, the lateral wall of the endogenous fire cage with
The main fiery gas outlet pipe is docking together, and setting in this way comes out central flame gas outlet pipe and main fiery gas outlet pipe
Combustion gas can smoothly enter in center blast tube and main blast tube, and inner fire cover, outer fire cover can be made to generate flame；The flange
B is placed in outer fire cover seat bottom, and the arcwall face of flange B is with the identical cambered surface of diameter, in this way with the inner wall of outer fire cover seat
Setting structure design is reasonable.
A circle groove is equipped at the fascia edge of the outer fire cover seat bottom of the tray for combustion, the setting of this circle groove can prevent
Soup enters from the top in outer arcuate face.
The endogenous fire cage is upper to have an outlet trunnion ring A at the bottom in hole；The lateral wall bottom of the endogenous fire cage
Portion has an outlet trunnion ring B.The setting of outlet trunnion ring A and outlet trunnion ring B improve endogenous fire cage and central flame combustion gas
The fitness of escape pipe, main fiery gas outlet pipe.
After adopting the above structure, the present invention is high with thermic load, firepower is big, the thermal efficiency is high, Yi Genghuan nozzle, maintenance side
Just, using it is safe the features such as.
