Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Example 1
Referring to fig. 1-3, embodiment 1 of the present invention provides a burner with adjustable fire hole fire form, which comprises a fire cover 1 and a burner head 2, wherein a central fire channel 11 and an outer ring fire channel 12 are vertically arranged on the fire cover 1, the upper end of the central fire channel 11 corresponds to a central fire hole 13, and the upper end of the outer ring fire channel 12 corresponds to an outer ring fire hole 14. The furnace end 2 is provided with a gas channel 21 and an injection pipe channel 22, the injection pipe channel 22 is connected with gas, one end of the gas channel 21 is vertically communicated with the injection pipe channel 22, the other end of the gas channel 21 is in butt joint with the central flame path 11 and the outer ring flame path 12, the gas can be introduced into the central flame path 11 and the outer ring flame path 12 through the injection pipe channel 22 and the gas channel 21, and the gas sprayed out of the central flame holes 13 and the outer ring flame holes 14 is combusted through an ignition device. The burner 2 is also provided with a movable air passage changing assembly 3, and the movement of the air passage changing assembly 3 can lead the gas passage 21 to be communicated with the central flame path 11 singly or lead the gas passage 21 to be communicated with the central flame path 11 and the outer ring flame path 12 simultaneously.
In the structure of the burner of the present invention described above, the air passage can be changed by changing the movement of the air passage changing member 3 in the case where only one injection pipe passage 22 supplies air, so that the central flame holes 13 can be burned individually or the central flame holes 13 and the outer ring flame holes 14 can be burned simultaneously. Thus, under the condition of not changing the heat load of the fuel gas, the flame distribution on the fire cover 1 is changed, the change of the fire is realized, and the fire power can reach the central fire concentration or the large-area uniform fire distribution according to the requirements of users, thereby achieving the purpose of the invention.
Referring to fig. 1 and 2, in a specific embodiment of the burner structure of the present invention, the air passage changing assembly 3 includes a ventilation slider 31, which is disposed in the cavity between the furnace cover 1 and the gas passage 21, and the ventilation slider 31 can be moved under the driving of the adjusting device 4, so that the central flame path 11 and the outer ring flame path 12 are communicated or closed. When the central flame path 11 and the outer ring flame path 12 are closed, the central flame path 11 is communicated with the fuel gas channel 21, and fuel gas introduced by the injection pipe channel 22 enters the fuel gas channel 21 and the central flame path 11, so that the central flame hole 13 is combusted independently; when the central flame path 11 is communicated with the outer ring flame path 12, the central flame path 11 is communicated with the fuel gas channel 21, and the fuel gas introduced by the injection pipe channel 22 enters the fuel gas channel 21 at the moment, and then is split and simultaneously enters the central flame path 11 and the outer ring flame path 12, so that the central flame hole 13 and the outer ring flame hole 14 are combusted simultaneously. In this way, the central flame path 11 and the outer ring flame path 12 are communicated or closed only by the movement of the ventilation slide block 31, so that the air path conversion is realized, and the purpose of independent combustion of the central flame hole 13 or simultaneous combustion of the central flame hole 13 and the outer ring flame hole 14 can be achieved. The structure is simple and ingenious in design, and the gas can be split by arranging the movable ventilation slide block 31 in the cavity between the furnace cover 1 and the gas channel 21 under the condition that the size of the burner is not required to be changed.
In the illustrated embodiment of the invention, the movement of the ventilation slider 31 is accomplished by means of the adjustment device 4. The adjusting device 4 is arranged outside the furnace end 2 and is connected with the air exchanging slide block 31 through a transmission piece 5, and the adjusting device 4 drives the transmission piece 5 to move so as to drive the air exchanging slide block 31 to move, so that the central flame path 11 and the outer ring flame path 12 are communicated or closed. In this structure, only the ventilation slide block 31 is arranged in the furnace end 2, the adjusting device 4 is remotely controlled by the transmission piece 5, the structure and the size of the furnace end 2 can not be changed, and the layout of the whole structure is facilitated. It is understood that the air exchanging slide block 31 may be directly connected to an electromagnetic valve or an air cylinder, the electromagnetic valve or the air cylinder may be disposed in an inner cavity (not shown) of the gas channel 21, the air exchanging slide block 31 is connected to a valve rod of the electromagnetic valve or a piston rod of the air cylinder, and the valve rod of the electromagnetic valve or the piston rod of the air cylinder is driven to move by an electric control manner, so as to drive the air exchanging slide block 31 to move, and the purpose of moving the air exchanging slide block 31 may be achieved. Of course, this configuration results in a change in the size of the burner, which will not be described in detail herein.
With further reference to fig. 1 and 2, when the ventilation slider 31 is connected with the adjusting device 4 through the transmission member 5, the ventilation slider 31 includes a disc-shaped plug 311 and a transmission rod 312, where the disc-shaped plug 311 is horizontally disposed, and the transmission rod 312 is vertically disposed, and one end of the transmission rod is vertically connected with the disc-shaped plug 311, and the other end of the transmission rod is connected with the transmission member 5. Because the disc-shaped choke plug 311 is horizontally arranged, the central flame path 11 and the outer ring flame path can be blocked in a movable mode, meanwhile, two half-moon-shaped through holes 34 are formed in the disc-shaped choke plug 311, and the two through holes 34 are communicated with the central flame path 11 and the fuel gas channel 21. When the disc-shaped choke plug 311 moves upwards to just prop against the central flame path 11 and the outer flame path 12, the fuel gas channel 21 and the outer flame path 12 are not communicated, and the central flame path 11 is still communicated with the fuel gas channel 21 due to the arrangement of the two through holes 34, and at the moment, fuel gas of the injection pipe channel 22 can still enter the central flame path 11 from the fuel gas channel 21 through the through holes 34; when the disc-shaped choke plug 311 moves downwards, the central flame path 11 is communicated with the outer ring flame path 12, and the fuel gas introduced by the injection pipe passage 22 can enter the central flame path 11 from the fuel gas passage 21 through the through hole 34, and the fuel gas entering the central flame path 11 can be split into the outer ring flame path 12. Further, the elastic member 32 may be sleeved on the transmission rod 312. The elastic member 32 can rely on the elasticity of the elastic member, so that when the disc-shaped plug 311 seals the outer ring flame path 12, the central flame path 11 and the outer ring flame path 12 can be reliably propped against by the elasticity of the elastic member 32, and the unstable and reliable communication between the central flame path 11 and the outer ring flame path 12 can be ensured.
Referring to fig. 2, in a specific embodiment, a hollow boss 23 may be disposed at the center of the gas channel 21 in an upward direction without changing the size of the burner, and the driving rod 312 may be inserted into the hollow of the boss 23, and driven by the driving member 5 to move, so that the positioning and guiding of the driving rod 312 are facilitated due to the hollow boss 23. Further, one end of the elastic member 32 may be located at the bottom of the disc plug 311, and the other end is located at the top of the hollow boss 23, so that the elastic member 32 may be reliably fixed. It will be appreciated that the elastic member 32 may be a spring or other elastic member, and specifically, the elastic member 32 may be positioned on the transmission rod 312 by a fixing member 33, where the fixing member 33 is disposed at the bottom of the transmission rod 312, and may be used to connect the transmission member 5 to connect the transmission rod 312 with the transmission member 5.
Referring to fig. 1 and 3, in the structural embodiment of the burner of the present invention, the adjusting device 4 includes an adjusting switch 41, the adjusting switch 41 is disposed on the existing stove knob 6, the middle portion of the stove knob 5 can be hollowed out, the adjusting switch 41 is embedded in the middle groove 61 of the stove knob 6, and then connected with the ventilation slider 31 on the air passage changing assembly 3 through the transmission member 5 (the illustrated embodiment is connected with the transmission rod 312 through the fixing member 33). Thus, the adjusting switch 41 is arranged on the kitchen knob 6, so that the structure can be improved and configured on the basis of the existing kitchen knob 6, the operation habit of a user is met, and meanwhile, the control is facilitated. Of course, it is also possible to configure the knob on the hob alone to fit the fixed adjustment means 4.
Since the adjusting device 4 is a remote control ventilation slide 31, the transmission 5 can preferably be a pull rope or a pull rope.
Referring to fig. 3 specifically, the adjusting switch 41 includes an adjusting slider 411, a sliding shaft 413 and a limiting rod 412, wherein the limiting rod 412 and the sliding shaft 413 are both fixed on the kitchen knob 6; the adjusting slide 411 is sleeved on the sliding shaft 413, so that the adjusting slide 411 is easy to slide and the adjusting slide 411 is prevented from being separated. The adjusting slide block 411 is provided with an upward shifting block, and protrudes out of the kitchen range knob 6, so that the user can conveniently control the kitchen range knob; the adjusting slide 411 is further provided with a first limiting hole 415 and a second limiting hole 416, and the limiting rod 412 can be inserted into the first limiting hole 415 or the second limiting hole 416 to be positioned according to the requirement by moving the adjusting slide 411. The first limiting hole 415 or the second limiting hole 416 may be a kidney-shaped hole, which is beneficial to the insertion and the insertion of the limiting rod 412. Meanwhile, a chute 62 is also arranged on the kitchen knob 6 and can be matched with the adjusting slide block 411, so that the sliding and guiding of the adjusting slide block 411 are facilitated. In specific adjustment, a user can drive the adjustment slide 411 to move transversely along the sliding shaft 413 through a shifting block on the adjustment slide 411, so that the adjustment slide 411 is separated from the limit of the limiting rod 412, the adjustment slide 411 enters the sliding groove 62, and then the adjustment slide 411 is driven to move longitudinally along the sliding groove 62 through the shifting block, so that the adjustment slide 411 can be moved to a position corresponding to the first limiting hole 415 or the second limiting hole 416 of the limiting rod 412, and the adjustment slide 411 is fixed. Since the adjusting slide 411 is connected with the ventilation slide 31 through the transmission member 5, the fixed positions of the first limiting hole 415 and the second limiting hole 416 through the limiting rod 412 are the positions where the ventilation slide 31 moves to connect or close the central flame path 11 and the outer ring flame path 12, respectively. In this way, through the movement of the adjusting slide 411 and the cooperation of the first limiting hole 415 or the second limiting hole 416 and the limiting rod 412, the adjusting slide 411 can be fixed at different positions, so that the position of the ventilation slide 31, that is, the position of the disc-shaped plug 311 in the fire cover 1, is adjusted, remote control of the adjusting device 4 is realized, and the fuel gas entering the central fire channel 11 can be concentrated or split according to the needs of a user.
Further, since the adjusting device 4 is remotely controlled by the driving member 5, when the driving member 5 is a pull rope or a pull rope, the driving member needs to be guided and tensioned, and therefore, in the specific embodiment of the burner structure of the invention, the burner structure is further provided with the fixed pulley 42 and the steering shaft 414, the fixed pulley 42 can be arranged outside the burner 2, and the pull rope or the pull rope is wound around the periphery of the fixed pulley 42; the steering shaft 414 can be arranged on the kitchen knob 6, and after the stay rope or the stay rope is connected with the adjusting slide block 411, the transmission direction of the steering shaft 414 can be changed, and the steering shaft is connected with the ventilation slide block 31, so that the kitchen range is rapid and convenient.
The working process of the embodiment 1 of the invention is as follows:
When the air inlet valve is opened, mixed gas of fuel gas and air enters the furnace end 2 from the furnace end 2 through the injection pipe 22, when the adjusting slide block 411 is at an initial position, the limiting rod 412 is clamped in the first limiting hole 415, the transmission part 5 is in a loose state, the elastic part 32 is against the air exchanging slide block 31 by virtue of elasticity of the elastic part, at the moment, the outer periphery of the disc-shaped plug 311 provided with the through hole 34 on the air exchanging slide block 31 fully blocks the outer ring flame path 12, the mixed gas only can pass through the through hole 34 provided on the disc-shaped plug 311 to reach the central flame path 11, and the central flame hole 13 burns; when the flame range needs to be enlarged, a user can move the adjusting slide block 411 on the kitchen knob 6, the transmission piece 5 drives the disc-shaped plug 311 to move downwards, the elastic piece 32 is compressed, the disc-shaped plug 311 leaves the blocking position when the limiting rod 412 is clamped in the second limiting hole 416, the central flame path 11 and the outer ring flame path 12 are communicated, mixed gas in the burner 2 flows to the central flame path 11 and the outer ring flame path 12 respectively, and the central flame hole 13 and the outer ring flame hole 14 burn.

The working process of the embodiment 2 of the invention is as follows:
When a user uses the gas stove, firstly, the adjusting valve is controlled to be opened through the stove knob 6, so that mixed gas of gas and air enters the stove head 2, and the mixed gas is sprayed out from the fire cover 1 and is ignited by the ignition device to form flame. When a user needs to use concentrated fire (cook less food or slowly heat), the user can control the position of the air exchanging slide block 31 by the adjusting slide block 411 on the kitchen knob 6 to be positioned at the position of the first limiting hole 415, so that mixed gas enters the gas channel 21 from the injection pipe channel 22 and passes through the through hole 34 formed on the disc-shaped plug 311 to reach the central flame path 11, and the central flame hole 13 burns to form central flame. When the flame range needs to be enlarged (such as a cake with larger cooking area or a fried fish with small fire with large area), the adjusting slide block 411 on the kitchen knob 6 can be moved to be positioned at the second limiting hole 416 so as to control the position of the ventilation slide block 31, at the moment, part of mixed gas in the burner 2 is shunted to the outer ring flame path 12 and is sprayed out from the outer ring flame hole 14 to form another group of flames, so that two annular flames are formed on the fire cover 1, and the flame range and the burning area are enlarged under the condition of not changing the heat load. In the whole adjusting process, the mixing ratio of the mixed gas entering the furnace end 2 from the valve body and the content of the fuel gas are not changed.
By adopting the scheme, compared with the prior art, the invention can control the trend of the gas in the burner of the burner, and finally the gas stove can achieve the effect of changing the flame distribution of the stove under the condition of not changing the load.
