Background technology:
In the modern life, use the liking deeply by housewife of gas-cooker, it is greatly convenient to bring to the life of people, general gas stove needs a large amount of auxiliary airs to carry out auxiliary could burning completely when burning, this just needs to keep larger distance between the bottom of a pan and burner, otherwise the bad phenomenon that there will be incomplete combustion of twice aeration, remote heating process makes the thermal efficiency of gas-cooker very low, the good level of general gas stove also only has about 50%, and the energy of half is wasted, in order to solve the lower problem of the thermal efficiency, many enterprises have all carried out the research and development of air blowing gas range technology, if Chinese Patent Application No. is the utility model patent of CN201120541655.1, authorized announcement date is on August 22nd, 2012, disclose " air blowing gas range burner ", described in it: the output of induction tunnel is provided with distributor, at the input of induction tunnel, air blast is set, be provided with in induction tunnel separate in ring fire injection passage and outer ring fire injection passage, the entrance of interior ring fire injection passage and outer ring fire injection passage is aimed in the outlet of described air blast, such scheme design can in the object to a certain degree reaching economize energy and the increase thermal efficiency, but structure is too simple, just air blast is directly aimed at distributor by induction tunnel, this structure is difficult to air and combustion gas to carry out Homogeneous phase mixing in induction tunnel, therefore there will be the phenomenon of the uneven and de-fire of burning, burning quality is not high.
Summary of the invention:
Object of the present invention is exactly the deficiency in order to solve prior art, and the structure provided is simple, premixed combustion is effective, the Draught gas burner of obvious energy conservation full premix injection control device.
The present invention's adopted technical scheme of dealing with problems is achieved in that and the present invention includes burner, premix barrel, Venturi tube, blast switch, blower fan and gas joint; It is characterized in that: between the high pressure air port and the premix barrel of burner of blower fan, or the air inlet of blower fan is provided with induction tunnel; Be provided with Venturi tube in induction tunnel, be provided with venturi waist hole between the contraction chamber and expansion cavity of Venturi tube, venturi waist hole is circular or long linear hole; There is the gap of 3-8 millimeter between venturi waist hole and induction tunnel, form negative pressure cavity.
Induction tunnel is mounted with gas joint communicate with negative pressure cavity; Be provided with throttling valve core in gas joint, throttling valve core has throttle orifice.
In high pressure air port, place is provided with pressure tap, communicates with blast switch;
Air register is equipped with in air inlet.
Compared with the prior art, beneficial effect is embodied in the present invention:
1, the present invention adopts in induction tunnel and arranges Venturi tube, between the Venturi tube waist hole and induction tunnel of Venturi tube, there is the gap of 3-8 millimeter to form negative pressure cavity, the wind blasted is from contraction chamber through expansion cavity, and combustion gas is introduced expansion cavity uniformly at venturi waist hole place and mixed.
2, the gas joint that the present invention settles on induction tunnel communicates with negative pressure cavity; Be provided with throttling valve core in gas joint, regulate the size of throttle orifice, can thermic load be changed, deduct gas nozzle.
3, the present invention is provided with blast switch at high pressure air port place, improves burner security in combustion and controllability.
4, the present invention is equipped with air register in air inlet, increases the amplitude of accommodation of air quantity.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 is induction tunnel detonation configuration schematic diagram of the present invention;
Fig. 3 is another embodiment of the present invention structural representation;
Detailed description of the invention:
By the following examples, the invention will be further described by reference to the accompanying drawings;
Description of reference numerals: 1-burner, 2-premix barrel, 3-Venturi tube, 4-induction tunnel, 5-venturi waist hole, 6-negative pressure cavity, 7-blast switch, 8-blower fan, 9-air inlet, 10-air register, 11-pressure tap, 12-high pressure air port, 13-contraction chamber, 14-gas joint, 15-throttle orifice, 16-throttling valve core, 17-expansion cavity.
Embodiment: see accompanying drawing 1, Fig. 2; The present invention includes burner (1), premix barrel (2), Venturi tube (3), blast switch (7), blower fan (8) and gas joint (14); Induction tunnel (4) is provided with between the high pressure air port (12) and the premix barrel (2) of burner (1) of blower fan (8); Venturi tube (3) is provided with in induction tunnel (4), the venturi waist hole (5) of Venturi tube (3) is circular port, aperture is 1 millimeter, there is the gap of 5 millimeters between venturi waist hole (5) and induction tunnel (4), form negative pressure cavity (6); Induction tunnel (4) is mounted with gas joint (14) communicate with negative pressure cavity (6), in gas joint (14), is provided with throttling valve core (16); High pressure air port (12) place is provided with pressure tap (11), communicates with blast switch (7); Air register (10) is equipped with at air inlet (9) place.
