[0032] This embodiment provides a gas distribution device 40 for a burner. Figure 1 is a schematic structural diagram of a burner provided according to an embodiment of the present invention, Figure 2 is Figure 1 a schematic exploded view of the burner shown, as Figure 1 and Figure 2As shown in the figure, the gas distribution device 40 includes a partition plate 41, at least one first partition cylinder 42, and a plurality of vertical partition plates 44. The partition plate 41 has a plurality of partition zones arranged uniformly along its circumferential direction, and each partition zone has at least two sub-partition zones. The at least two sub-partition zones are arranged in sequence along the circumferential direction of the partition plate 41. A communication hole 411 is provided on each sub-partition zone to form at least two groups of communication holes 411, and the at least two groups of communication holes 411 are arranged in sequence along the radial direction of the partition plate 41.

[0033] At least one first partition cylinder 42 is disposed below the partition plate 41 to divide the lower side of the partition plate 41 into at least two communication spaces arranged in sequence along the radial direction of the partition plate 41. Each communication space communicates with a corresponding group of communication holes 411. A plurality of vertical partition plates 44 are disposed above the partition plate 41, and each vertical partition plate 44 is located between two adjacent sub-partition zones to define an air supply space communicating with each communication hole.

[0034] When supplying gas, as Figures 6 to 8 shown, the gas first enters the communication space, undergoes circumferential diffusion and upward movement in the communication space, moves to the upper side of the partition plate 41 through a corresponding group of communication holes 411, diffuses radially and moves upward in the corresponding air supply space on the upper side of the partition plate 41 for gas transmission. Each air supply space extends along the radial direction of the partition plate, and partial communication space air supply can be realized, enabling some air supply spaces to supply air upward. Furthermore, it is convenient to make the upper burner cap have multiple fire outlet zones, and it is possible to ignite the fire outlet structures on some fire outlet zones as needed on the same burner cap, realizing partial heating of the fire outlet zones in the circumferential direction of the burner cap and extinguishing the other fire outlet zones, which can solve the problem that only the central fire heats the bottom of the pot when the burner is in a small fire state, and further realize large-area and uniform small-fire heating of the entire burner cap on the pot.

[0035] In some embodiments of the present invention, the gas distribution device 40 further includes one or more second partition cylinders 43. Each second partition cylinder 43 is disposed in a corresponding communication space to divide the corresponding communication space into a gas transmission space and other spaces. The gas transmission space communicates with a corresponding group of communication holes 411. The other spaces can be used for making way, screw structure installation, etc. The multiple sub-partition zones corresponding to each group of communication holes 411 are arranged uniformly along the circumferential direction of the partition plate 41.

[0036] As Figure 1 shown, and referring to Figures 2 to 10 , the present invention also provides a burner 100, which includes a base 30, a burner cap 20, and the gas distribution device 40 in any of the above embodiments. The burner cap 20 is installed on the base 30. The gas distribution device 40 is disposed in the space defined by the base 30 and the burner cap 20. As Figure 9As shown, a plurality of air supply ports 31 are provided on the base 30, and each group of air supply ports 31 communicates with a communication space. Each vertical partition 44 is integrally formed with the burner cap 20, or each vertical partition 44 is integrally formed with the partition plate 41.

[0037] As Figures 3 to 5 shown, the upper surface of the burner cap 20 has a plurality of fire outlet areas 211, and each fire outlet area 211 is located above a gas supply space. That is to say, a plurality of fire outlet areas 21 are provided on the upper surface of the burner cap 20 and are evenly arranged along the circumferential direction of the burner cap 20, and at least two fire outlet areas 211 are provided on each fire outlet area 21, and at least two fire outlet areas 211 are arranged in sequence along the circumferential direction of the burner cap 20. At least one first fire outlet structure 22 is provided on each fire outlet area 211.

[0038] The burner cap 20 is provided with fire outlet partitions, that is, a plurality of fire outlet areas 21 are provided, and a plurality of fire outlet areas 211 are provided on each fire outlet area 21. When used in conjunction with the air supply of the air distribution device 40, it is possible to ignite the fire outlet structures on some of the fire outlet areas 211 as needed on the same burner cap 20, so as to heat some of the fire outlet areas 211 in the circumferential direction of the burner cap 20 and extinguish the remaining fire outlet areas, which can solve the problem that only the central fire heats the bottom of the pot when the burner is in a small fire, and further realize the large-area and uniform small-fire heating of the entire burner cap 20 of the burner on the pot. For example, the plurality of fire outlet areas 211 on each fire outlet area 21 may include a first fire outlet area and a second fire outlet area to form a plurality of first fire outlet areas and a plurality of second fire outlet areas. According to the needs, only a plurality of first fire outlet areas, or only a plurality of second fire outlet areas, or a plurality of first fire outlet areas and a plurality of second fire outlet areas are ignited at the same time to achieve different firepower heating.

[0039] In some embodiments of the present invention, each first fire outlet structure 22 includes a plurality of fire outlet holes, and the plurality of fire outlet holes are arranged in sequence along the radial direction of the burner cap 20. For example, each fire outlet hole is a circular hole or a strip hole, each strip hole extends along the circumferential direction of the burner cap 20, or each strip hole is perpendicular to the radial direction of the burner cap 20. The plurality of fire outlet holes of each first fire outlet structure 22 include a plurality of first fire outlet holes and a plurality of second fire outlet holes, and the plurality of first fire outlet holes and the plurality of second fire outlet holes are arranged at intervals in sequence along the radial direction of the burner cap 20. The cross-sectional area of the first fire outlet hole is smaller than the cross-sectional area of the second fire outlet hole. In some alternative embodiments of the present invention, each first fire outlet structure 22 is a linear fire hole extending along the radial direction of the burner cap 20. In some other alternative embodiments of the present invention, each first fire outlet structure 22 is a curved fire hole, and one end of the curved fire hole is close to the middle of the burner cap 20 and the other end is close to the periphery of the burner cap 20. That is to say, in the embodiments of the present invention, each first fire outlet structure 22 is configured such that the flame on the upper surface of the burner cap 20 can cover more than 50% of the entire burner cap 20 in the radial direction.

[0040] In some embodiments of the present invention, in order to better adjust the firepower, on each fire outlet area 21, the firepower formed by at least one first fire outlet structure 22 on at least one fire outlet area 211 is different from the firepower formed by at least one first fire outlet structure 22 on other fire outlet areas 211. For example, on each fire outlet area 21, the number of first fire outlet structures 22 on at least one fire outlet area 211 is different from the number of first fire outlet structures 22 on other fire outlet areas 211. Correspondingly, the size of the corresponding fire outlet area 211 can be set accordingly. In some alternative embodiments, the number of first fire outlet structures 22 on it can be adjusted by changing the area of the fire outlet area 211. For example, all the first fire outlet structures 22 are evenly distributed on the burner cap 20, and the area of one fire outlet area 211 can be twice that of another fire outlet area 211, etc., so that the number of first fire outlet structures 22 on one fire outlet area 211 is twice that of the first fire outlet structures 22 on another fire outlet area 211, etc.

[0041] In some embodiments of the present invention, the burner cap 20 has an annular top wall, an inner peripheral wall extending downward from the inner circumferential edge of the annular top wall, and an outer peripheral wall extending downward from the outer circumferential edge of the annular top wall. A plurality of second fire outlet structures 23 are provided on the inner peripheral wall and / or the outer peripheral wall, and each second fire outlet structure 23 is correspondingly arranged with a first fire outlet structure 22 to work synchronously.

[0042] As Figure 10 shown, when the burner 100 of the embodiment of the present invention is installed and used in a gas stove, the burner cap 20 can be used as an outer ring burner cap. When adjusting the firepower, such as reducing the firepower, the inner ring fire 300 is not turned off, and some fire outlet areas 211 of the burner cap 20 are made to fire, so as to reduce the firepower. When the firepower is reduced, the problem that only the central fire heats the bottom of the pot when the burner 100 is in a small fire can be solved, and further, the entire burner cap 20 of the burner 100 can evenly heat the pot with a small fire over a large area. In some embodiments of the present invention, the inner ring fire, middle ring fire, etc. of the gas stove can all use the burner 100 in the embodiment of the present invention.
