The burner for the gas stove comprises a base body, wherein a gas cavity for containing gas is formed in the base body, a first fire outlet hole and a second fire outlet hole are formed in the base body, the radial distances from the first fire outlet hole to the center of the base body are different from those from the second fire outlet hole, the burner further comprises at least one core piece, a gas channel is formed in the core piece, and the gas channel is communicated with the gas cavity in a use state of the core piece; the core piece and the seat body have a first relative position relationship and a second relative position relationship, when the core piece is placed on the seat body and the core piece and the seat body are in the first relative position relationship, the gas channel is communicated with the first fire outlet hole, and the gas channel is blocked with the second fire outlet hole; when the core is placed on the base in the second relative positional relationship with the base, the gas passage communicates with the second fire hole and is blocked from the first fire hole.
The technical effect of above-mentioned scheme is embodied in, through the adjustment core piece with the relative positional relationship of pedestal can realize that the furnace head is by first fire hole goes out the fire or second fire hole goes out the fire, and the furnace end of a combustor just has different flame distribution, can satisfy the multiple demand of user.
The application provides a technical proposal with different technical conception, and the technical effect exceeds the level of the prior art.
Among them, in above-mentioned scheme, the relative position of first fire hole and second fire hole is different, and as required, first fire hole and second fire hole's play fire direction and/or aperture also can be different.
When the core piece and the seat body are in a first relative position relationship, the gas channel is communicated with the first fire hole and is blocked with the second fire hole; when the core piece and the seat body are in a second relative position, the gas channel is communicated with the second fire hole and is blocked from the first fire hole. The above-mentioned scheme can change the flame distribution of the burner, but the change of the flame distribution is not limited to two kinds of flame cohesion and flame total burner distribution, but can have more changes, for example, in one embodiment, the flame distribution of the burner has three kinds of change forms of flame cohesion, flame external spraying and flame total burner distribution; in another embodiment, the flame distribution of the burner has the form of a cohesive flame, an external flame spray, and an alternating cohesive and external flame spray. Therefore, the scheme can enable the flame distribution of the burner to change more remarkably, has more change types and more flexible forms, and can meet various cooking demands of various users.

The improvement of the embodiment can structurally facilitate the design of the gas channel and simplify the structure of the burner.
In one or more embodiments, the burner includes a plurality of independent gas passages, each of which corresponds to one of the first and second fire holes. Just because this scheme includes a plurality of independent gas passage, this scheme still has the advantage that can adjust the flame distribution of furnace end more nimble, and the flame of furnace end can have more various forms to distribute moreover, and then satisfies the various demands of various users. Wherein "the burner comprises a plurality of separate said gas passages" is to be understood as at least the outlet section of each gas passage being independent of each other, i.e. at least the section of the gas passage which meets the first and second fire holes is independent of each other. In some embodiments, the gas passages include inlet sections and outlet sections, the inlet sections of each gas passage communicating with each other to form an annular passage, the outlet sections of each gas passage being independent of each other. In other embodiments, the gas passages include an inlet section and an outlet section, each gas passage being independent of the other from the inlet section to the outlet section.
It should be noted that "each gas channel corresponds to one of the first fire holes and one of the second fire holes" does not mean that each gas channel is necessarily communicated with the corresponding one of the first fire holes and the corresponding one of the second fire holes at the same time. When the core piece and the seat body are in the first relative position relation, the gas channel is communicated with the corresponding first fire outlet hole; when the core piece and the seat body are in the second relative position relation, the gas channel is communicated with the corresponding second fire outlet hole.

The flame distribution of furnace end of this scheme has three kinds of forms, and the first fire hole that only goes out on the inner ring body goes out the fire, only the second fire hole that goes out on the outer ring body goes out the fire to go out the fire hole on inner ring body and the outer ring body and all go out the fire.
In one or more embodiments, the inner ring body and the outer ring body are respectively formed with protruding step portions on side walls facing each other, the step portions being for supporting the core member in a use state of the seat body. Therefore, through the simple step part, the inner ring body and the outer ring body are surrounded, a fuel gas cavity and a containing groove for containing the core piece are formed at the same time, and the fuel gas cavity is communicated with the containing groove, so that the structure design is extremely simplified, the relative position relation between the core piece and the seat body is convenient to adjust, and more flame distribution forms are obtained.

In this embodiment, each core is independent, so that the relative positional relationship of each core and the housing can be adjusted by the user, thereby making the flame distribution adjustment of the burner more free and flexible.
In one or more embodiments, one of the first fire-discharging holes and one of the second fire-discharging holes in communication with the same receiving groove at least partially overlap in a radial direction of the seat body.
In one or more embodiments, the core member is horizontally rotated 180 degrees after being separated from the base member and then placed in the receiving groove, so as to achieve switching between the relative positional relationship of the core member and the base member.
In order to ensure that the burner does not leak fire at a position where fire should not occur, in one or more embodiments, the housing is circular or annular, the receiving groove is a square groove and a plurality of the receiving grooves are distributed along the circumference of the housing, the core member has a shape matching with the receiving groove, and when the core member is received in the receiving groove, the core member closes the receiving groove such that the fuel gas of the fuel gas chamber flows out only from the first or second fire outlet holes.
In one or more embodiments, the gas channel extends in a straight line within the core and is inclined with respect to one wall of the core, or the gas channel extends in an L-shape within the core. Thus, when the gas channel is communicated with the first fire hole and is blocked with the second fire hole, the core piece is lifted up and horizontally rotated for 180 degrees and then put into the accommodating groove, and the gas channel is naturally communicated with the second fire hole and is blocked with the first fire hole.

[ detailed description ] of the application
For a further understanding of the objects, construction, features, and functions of the application, reference should be made to the following detailed description of the preferred embodiments.
Referring to fig. 1 to 4, fig. 1 is a perspective view of a burner according to a first embodiment of the present application; FIG. 2 is a cross-sectional view of a burner according to a first embodiment of the present application when the core and the base are in a first relative positional relationship; FIG. 3 is a perspective view of a base according to a first embodiment of the present application; fig. 4 is a cross-sectional view of a housing according to a first embodiment of the present application.
The burner 1 of the burner for a gas range of this embodiment has a ring shape and includes a ring-shaped base 10 and a ring-shaped core member 20 placed on the base 10.
The housing 10 has a gas chamber 11 for containing gas and a containing groove 12 for containing the core 20 (see fig. 4). Wherein, the holding groove 12 is an annular groove, and the holding groove 12 is communicated with the gas cavity 11. The core member 20 is adapted to be received in the receiving groove 12 and rotatable relative to the receiving groove 12.
In this embodiment, the base 10 actually includes an inner ring 10a and an outer ring 10b, and the inner ring 10a and the outer ring 10b are connected by a connecting rib 14 to form the base 10. Protruding step portions 13 are formed on side walls of the inner ring body 10a and the outer ring body 10b facing each other, respectively. In the use state of the base 10, as shown in fig. 2, the step portion 13 is used to support the core 20.
The base 10 is provided with a first fire hole 100 and a second fire hole 200, and the radial distances from the first fire hole 100 and the second fire hole 200 to the center of the base 10 are different. In particular, in the present embodiment, the first fire hole 100 is located on the inner ring of the base 10, and the second fire hole 200 is located on the outer ring of the base 10. The accommodating groove 12 is respectively communicated with the first fire hole 100, the second fire hole 200 and the gas cavity 11.
As shown in fig. 4, the first and second fire holes 100 and 200 are located at the same level. As shown in fig. 3, the first and second flame holes 100 and 200 are offset from each other in the radial direction of the base 10.
In this embodiment, as shown in fig. 1, a flame stabilizing slot 101 is further disposed between any two adjacent first fire holes 100, and a flame stabilizing slot 201 is disposed between any two adjacent second fire holes 200. The flame stabilizing groove 101 and the flame stabilizing groove 201 are not communicated with the gas cavity 11, if the first fire hole 100 or the second fire hole 200 has gas flowing out, the gas flows to the flame stabilizing groove 101 or the flame stabilizing groove 201, and when the burner works, the flame is formed at the flame stabilizing groove 101 or the flame stabilizing groove 201. The flame formed by the flame stabilizing groove is used for stabilizing the flame combustion of the corresponding first flame outlet hole or the second flame outlet hole.
As shown in fig. 2, a plurality of independent gas passages 21 are formed in the core member 20, the gas passages 21 including inlet sections 211 and outlet sections 212, the inlet sections 211 of each gas passage 21 being communicated with each other to form an annular passage, the outlet sections 212 of each gas passage 21 being independent of each other. Each gas channel 21 is T-shaped in radial cross section of the core 20. Each gas passage 21 corresponds to one first fire hole 100 and one second fire hole 200. In the use state of the core 20, the gas channel 21 communicates with the gas chamber 11.
The core 20 of the present embodiment has a first relative positional relationship and a second relative positional relationship with the base 10.
As shown in fig. 2, the burner 1 shown in fig. 2 is a cross-sectional view when the core member 20 and the base 10 are in a first relative positional relationship. When the core 20 is placed on the base 10 and the core 20 is in a first relative positional relationship with the base 10, the gas passage 21 communicates with the first fire hole 100, and the gas passage 21 is blocked from the second fire hole 200. The dashed line with an arrow in fig. 2 indicates the flow direction of the fuel gas, and the fuel gas in the fuel gas chamber 11 flows out from the first fire hole 100 through the gas passage 21. At this time, only the first flame outlet 100 in the inner ring of the burner 1 is discharged with fuel gas, and the burner is ignited to form flame. The second flame holes 200 located at the outer ring are not discharged with fuel gas, and thus flame cannot be formed. When the burner 1 works, only the inner ring has flame, and at the moment, the flame of the burner 1 is cohesive, so that the burner is suitable for heating cooking appliances with smaller diameters, such as milk pots, small frying pans and small soup pots.
It should be noted that the dashed line with an arrow in fig. 2 is only a simple illustration of the flow direction of the fuel gas, and does not represent the actual direction of the fire exiting the first fire exit hole 100, and in fact, by adjusting the angle of the first fire exit hole 100, the direction of the fire exiting the first fire exit hole 100 may be adjusted, such as being inclined upwards.
When the core 20 is placed on the housing 10 with the core 20 in a second relative positional relationship with the housing 10, the gas passage 21 communicates with the second fire hole 200, and the gas passage 21 is blocked from the first fire hole 100 (not shown). At this time, only the second flame outlet 200 in the outer ring of the burner 1 is discharged with fuel gas, and the burner is ignited to form flame. The first flame holes 100 located in the inner ring have no fuel gas flowing out, i.e., no flame is formed. When the burner 1 works, only the outer ring has flame, and at the moment, the flame of the burner 1 is sprayed outwards, so that the burner is suitable for heating cooking appliances with larger diameters, such as a large frying pan.
In this embodiment, when the core 20 and the base 10 are in the first relative positional relationship, the core 20 and the base 10 can be in the second relative positional relationship by rotating the core 20. The core member 20 is rotated back to return the core member 20 and the base 10 to the first relative position. Since the first and second fire holes 100 and 200 are distributed to be staggered from each other in the radial direction of the base 10. When the core 20 and the base 10 are in the first relative positional relationship, the gas passage 21 communicates with the first fire hole 100, and the gas passage 21 is blocked from the second fire hole 200. When the core 20 is rotated to bring the core 20 into a second relative positional relationship with the housing 10, the gas passage 21 communicates with the second fire hole 200, and the gas passage 21 is blocked from the first fire hole 100.
The angle of rotation of the core 20 may be specifically determined according to the distribution of the first and second fire holes 100 and 200. In order to remind the user, corresponding position marks may be provided on both the seat and the core, so as to remind the user that the core 20 is in a first relative position relationship with the seat 10 and the core 20 is in a second relative position relationship with the seat 10.
In order to maintain the core 20 and the housing 10 in a corresponding relative positional relationship, positioning structures, such as positioning studs and positioning holes, may be provided at corresponding locations on the housing and the core. When the core 20 is placed on the base 10 and the core 20 and the base 10 are in a first relative positional relationship, the core 20 can be rotated by a certain angle after being removed from the base 10, and then the core 20 is placed on the base 10, so that the core 20 and the base 10 are in a second relative positional relationship.
Next, a burner 2 according to a second embodiment of the present application is described with reference to fig. 5 to 8, wherein fig. 5 is a perspective view of a base of the second embodiment of the present application; FIG. 6 is a cross-sectional view of a housing according to a second embodiment of the present application; FIG. 7 is a cross-sectional view of a burner according to a second embodiment of the present application when the core and the base are in a first relative positional relationship; FIG. 8 is a cross-sectional view of a burner of a second embodiment of the present application with the core and the housing in a third relative positional relationship.
The same or similar structures in this embodiment and the first embodiment are denoted by the same or similar reference numerals, and the functions and actions thereof are the same or similar, and will not be described again here. Unlike the first embodiment, the housing 30 of the present embodiment includes an inner ring body 30a provided with a first fire hole 100 and an outer ring body 30b provided with a second fire hole 200, the outer ring body 30b being provided at the outer periphery of the inner ring body 30a and surrounding both to form a fuel chamber 31 and a receiving groove 32 for receiving the core member 20. The accommodating groove 32 is respectively communicated with the first fire hole 100, the second fire hole 200 and the gas cavity 31. The inner ring 30a is rotatable relative to the outer ring 30b such that the core 20 has a third relative positional relationship with the housing 30.
The inner ring 30a and the outer ring 30b are formed with protruding stepped portions 33 on side walls facing each other, respectively, as shown in fig. 7 and 8, the stepped portions 33 being for supporting the core 20 in the use state of the housing 30.
As shown in fig. 7, similar to the previous embodiment, when the core 20 is placed on the base 30 with the core 20 and the base 30 in the first relative positional relationship, the gas passage 21 communicates with the first fire hole 100, and the gas passage 21 is blocked from the second fire hole 200. The broken line with an arrow in fig. 7 indicates the flow direction of the fuel gas, and the fuel gas in the fuel gas chamber 31 flows out from the first flame holes 100 through the gas passage 21. When the burner 2 works, only the inner ring has flame.
When the core 20 is placed on the housing 30 with the core 20 in a second relative positional relationship with the housing 30, the gas passage 21 communicates with the second fire hole 200 and the gas passage 21 is blocked from the first fire hole 100 (not shown). At this time, only the second flame outlet 200 in the outer ring of the burner 1 is discharged with fuel gas, and the burner is ignited to form flame. When the burner 2 works, only the outer ring has flames.
As shown in fig. 8, when the core 20 is placed on the base 30 and the core 20 and the base 30 are in the third relative positional relationship, the gas passage 21 communicates with both the first fire hole 100 and the second fire hole 200. The broken line with an arrow in fig. 8 indicates the flow direction of the fuel gas, and the fuel gas in the fuel gas chamber 31 flows out from the first flame-out holes 100 and the second flame-out holes 200 through the gas passage 21. When the burner 2 works, the inner ring and the outer ring are provided with flames.
In the present embodiment, when the core member 20 is placed in the seat body 30, the switching between the first relative positional relationship and the second relative positional relationship of the core member 20 and the seat body 30 can be achieved by rotating the core member 20. By rotating the outer ring 30b or the inner ring 30a, the core member 20 and the seat body 30 can be switched from the first relative positional relationship or the second relative positional relationship to the third positional relationship.
The present embodiment has a further advantage over the first embodiment in that the burner 2 may have a more flame distribution pattern.
Here, the dashed lines with arrows in fig. 7 and 8 are only a simple illustration of the flow direction of the fuel gas, and do not represent the actual final fire direction, and in fact, the fire direction may be adjusted by adjusting the angles of the first fire hole 100 and the second fire hole 200.

Wherein one core 40 is placed in correspondence of one receiving groove 52.
As shown in fig. 10 to 13, the first and second fire holes 100 and 200 are located at the same level. And, a first fire hole 100 and a second fire hole 200 communicating with the same receiving groove 52 are at least partially overlapped in the radial direction of the housing 50.
The seat 50 is annular, the receiving groove 52 is a square groove, and the plurality of receiving grooves 52 are uniformly distributed along the circumferential direction of the seat 50. The core 40 has a shape matching the receiving groove 52, i.e., the core 40 is in the shape of a rectangular parallelepiped. When the core 40 is accommodated in the accommodation groove 52, the core 40 closes the accommodation groove 52 such that the fuel gas of the fuel gas chamber 51 flows out only from the first flame-out hole 100 or the second flame-out hole 200.
The gas passage 41 extends in a straight line in the core 40 and the gas passage 41 is inclined with respect to one wall surface of the core 40.
As shown in fig. 11, when all the core pieces 40 and the seat body 50 are in the first relative positional relationship, the gas passage 41 communicates with the first fire hole 100 while blocking with the second fire hole 200. The dashed arrow in fig. 11 illustrates the flow direction of the fuel gas, and at this time, the fuel gas flows out from the first fire hole 100 through the gas passage 41. When the burner 3 works, only the inner ring has flame, and the flame of the burner 3 is cohesive.
When all of the core pieces 40 and the housing 50 are in the second relative positional relationship, as shown in fig. 12, the gas passage 41 communicates with the second fire hole 200 while blocking with the first fire hole 100. The dashed arrow in fig. 12 indicates the flow direction of the fuel gas, and at this time, the fuel gas flows out from the second flame holes 200 through the gas passage 41. When the burner 3 works, only the outer ring has flames, and the flames of the burner 3 are sprayed outwards.
Wherein, the core member 40 is horizontally rotated 180 degrees after being separated from the base 50 and then placed in the receiving groove 52, so that the relative positional relationship between the core member 40 and the base 50 can be switched. When the core 40 and the base 50 are in the first relative positional relationship as shown in fig. 11, the core 40 is removed from the base 50, horizontally rotated 180 degrees and then placed in the receiving groove 52, and the core 40 and the base 50 are in the second relative positional relationship as shown in fig. 12.
As shown in fig. 13, the burner 3 may further have a first relative positional relationship between a portion of the core 40 and the base 50, and a second relative positional relationship between a portion of the core 40 and the base 50. In order to obtain a more uniform flame distribution, the core 40 in a first relative positional relationship with the housing 50 and the core 40 in a second relative positional relationship with the housing 50 are staggered with respect to one another.
