[0065] In the embodiment, the number of the outer pilot channels 13 is four, and the four outer pilot channels 13 are arranged uniformly at intervals on the periphery of the inner pilot channel 12. In other embodiments, the number of the outer pilot channels 13 can also be two, three, five or any other number, which can be designed according to the needs.

[0066] In order to automatically control the fire size of the stove 100, as shown in the accompanying drawings, Figure 4 In combination with Figure 2 As shown, the control module further comprises a sensor 106 mounted on the burner head 1, the sensor 106 is used to detect the distance between the sensor 106 and the bottom of the pot 200 located on the pot rack 104, and the control unit can control the fire size of the burner 103 according to the value detected by the sensor 106.

[0067] Continuing as shown in the accompanying drawings, Figure 5 In combination with Figure 3 As shown, the fire deck 2 comprises a seat body 21 and an inner convex ring 22 and an outer convex ring 23 protruding from the seat body 21, the seat body 21 is placed on the outer pilot channel 13 to ensure the stability of the fire deck 2; the outer convex ring 23 is arranged at intervals around the periphery of the inner convex ring 22, and the fire cap 3 is sleeved outside the inner convex ring 22, so as to facilitate the installation of the fire cap 3 and the outer ring cap 4 on the fire deck 2.

It should be noted that the adjusting space is the space below the above-mentioned containing space, and in an ideal state, the mixed gas can only enter the adjusting space, and cannot enter the space above the adjusting space through the air blocking ring 51. In addition, the fire outlet channel 30 located below the air blocking ring 51 (i.e., the fire outlet channel 30 located in the adjusting space) can receive the mixed gas, and the fire outlet channel 30 located above the air blocking ring 51 cannot receive the mixed gas, so that the air blocking ring 51 can be driven to move up and down to change the height of the adjusting space, so as to adjust the number of layers of the fire outlet channel 30 that can supply the mixed gas, and then adjust the fire amount of the fire cover 3, that is, the firepower of the burner 103.

[0074] In order to limit the lifting stroke of the air blocking ring 51, the inner side wall of the outer peripheral wall 41 has two limiting stop surfaces 412 arranged at intervals along the height direction thereof, and the two limiting stop surfaces 412 are oppositely arranged, and the air blocking ring 51 moves up and down between the two limiting stop surfaces 412. It should be pointed out that when the air blocking ring 51 abuts against the lower limiting stop surface 412, the lowest layer of the fire outlet channel 30 of the fire cover 3 can receive the mixed gas; when the air blocking ring 51 abuts against the upper limiting stop surface 412, all the fire outlet channels 30 of the fire cover 3 can receive the mixed gas. The air blocking ring 51 is lowered by one layer of the height of the fire outlet channel 30, that is, one layer of the fire outlet channel 30 is closed; the air blocking ring 51 is raised by one layer of the height of the fire outlet channel 30, that is, one layer of the fire outlet channel 30 is opened.

[0076] Figure 6 The structure of the telescopic member 52 provided by the embodiment of the application is shown. As shown in Figure 6 A plurality of telescopic members 52 are arranged at intervals along the circumference of the air blocking ring 51 to ensure the stability of the lifting of the air blocking ring 51. It can be understood that the number of the telescopic members 52 can be two, three, four, five, six, seven or any number, and the specific number can be designed according to the needs, which is not limited here.

[0077] Figure 7 A schematic diagram of the structure of the flame cover 3 provided in an embodiment of this application is shown. Figure 7 As shown, the flame cap 3 is composed of multiple first stacked pieces 31 and multiple second stacked pieces 32 stacked alternately. The outermost layer of the flame cap 3 is always a second stacked piece 32. Both the first stacked pieces 31 and the second stacked pieces 32 are annular, and adjacent first stacked pieces 31 and second stacked pieces 32 cooperate to form a flame outlet channel 30. In addition, the first stacked pieces 31 are high-temperature resistant metal sheets; the second stacked pieces 32 are high-temperature resistant metal sheets, for example, both the first stacked pieces 31 and the second stacked pieces 32 are stainless steel sheets.

[0078] It should be noted that, Figure 7 The first stacked sheet 31 and the second stacked sheet 32 ​​shown are both annular. In other embodiments, the first stacked sheet 31 and the second stacked sheet 32 ​​can also be annular in other shapes, such as elliptical annular or regular octagonal annular, as long as the first stacked sheet 31 and the second stacked sheet 32 ​​are sheet-like structures with a through hole in the middle, which is not limited here.

[0079] In this embodiment, there are six first stacked pieces 31 and seven second stacked pieces 32. The six first stacked pieces 31 and the seven second stacked pieces 32 are stacked alternately to form six layers of fire outlet channels 30. In other embodiments, the number of first stacked pieces 31 can be any number, such as three, four, five, seven, eight, nine, or ten, and can be designed as needed. There are no restrictions on this.

[0080] Figure 8 This illustration shows a schematic diagram of the structure of the first stacked piece 31 and the second stacked piece 32 in the flame cover 3 provided in an embodiment of this application.

[0081] Among them, the end of the flame outlet 30a located inside the burner cap 3 is the gas outlet end, and the end located outside the burner cap 3 is the gas inlet end. When the burner 103 does not have a baffle ring 51, the mixed gas enters the containment space (when the burner 103 has a baffle ring 51, the mixed gas enters the regulating space). Then, the mixed gas in the containment space can enter the flame outlet 30a through the gas inlet end of each flame outlet 30a, and finally enter the interior of the burner cap 3 from the gas outlet end of the flame outlet 30a for combustion.

[0082] In the embodiment, the plurality of recesses 311 are arranged at intervals with the center of the first lamination sheet 31 as the center, so as to facilitate the molding of the first lamination sheet 31 and improve the processing precision of the first lamination sheet 31.

[0083] The first lamination sheet 31 comprises an inner ring region 311 and an outer edge region 312 surrounding the outer periphery of the inner ring region 311, and the plurality of recesses 3111 are arranged at intervals uniformly in the inner ring region 311 with the center of the first lamination sheet 31 as the center. The surface of the outer edge region 312 can be attached to the surface of the second lamination sheet 32. In this way, the outer edge of each layer of the fire outlet passage 30 has a buffer passage formed by the cooperation of the outer edge region 312 of the first lamination sheet 31 and the second lamination sheet 32, that is, the mixed gas in the accommodation space (or adjustment space) first enters the buffer passage and then enters the inside of the fire cap 3 through each fire outlet hole 30a, thereby improving the air intake amount of each fire outlet hole 30a.

[0084] The second lamination sheet 32 is flat, and the outer edge region 312 is flat, so as to ensure that the first lamination sheet 31 and the second lamination sheet 32 are stably attached, thereby forming a stable drainage fire outlet passage 30, and making each fire outlet hole 30a of each layer of the fire outlet passage 30 independent of each other, realizing the shunt drainage of the mixed gas and ensuring that the mixed gas flows into the fire cap 3 in an orderly manner.

[0085] The center line of the fire outlet hole 30a extends along the radial direction of the fire cap 3, so as to shorten the path of the fire outlet hole 30a and improve the air intake efficiency of the mixed gas into the inside of the fire cap 3.

[0086] The flow area of the fire outlet hole 30a gradually decreases from the air intake end to the air outlet end. Since the flow area of the air intake end of the fire outlet hole 30a is larger, more mixed gas enters the fire outlet hole 30a, and the flow area of the air outlet end of the fire outlet hole 30a is smaller, so that the mixed gas in the fire outlet hole 30a can flow faster, the mixed gas entering the fire cap 3 has a higher flow rate, the collision effect of the mixed gas from different fire outlet holes 30a is increased, the air and the gas are further mixed uniformly, and the combustion efficiency is improved.

[0087] The cross-sectional shape of the fire outlet hole 30a can be isosceles trapezoidal. At this time, the fire outlet hole 30a can be a prism structure with a quadrilateral longitudinal section, or a conical structure with a substantially circular longitudinal section, which will not be described one by one here.

[0097] Figure 11 Another flowchart of the stove load matching control method provided by the present application is shown. As shown in the figure, Figure 11 in step S200, the following steps are included:

[0098] S201, judging whether the time when the stove 100 is in the current gear is greater than T1; if yes, executing S202. If no, it indicates that the user has performed manual adjustment.

[0099] T1 can be any value between 5s and 8s, such as 5s, 6s, 7s, 8s.

[0100] S202, start the sensor 106, and acquire parameters L, L1 and L2.

[0101] Wherein, the value of L is directly related to the size of the pot 200 and the bottom shape of the pot 200, therefore, L is acquired by the sensor 106 in real time and transmitted to the control module, L1 and L2 are related to the height size of the burner 103 and the height size of the pot holder 104, and the height size of the burner 103 and the height size of the pot holder 104 are fixed values, therefore, L1 and L2 can be input into the control module in the form of manually measured preset parameters, so as to be called by the control module when making decisions.

[0102] S203, determine the number n of layers of the fire outlet channel 30 to be closed according to the relationship among L, L1 and L2.

[0103] Wherein, That is, all the fire outlet channels 30 are in the open state, and the burner 103 is in the maximum firepower gear. The burner 103 in the maximum firepower gear can be suitable for the cooking demand of the pot 200 with large size.

[0104]

[0105] S204, control the lifting stroke Sx of the gas blocking ring 51 according to n, Sx is the distance between the gas blocking ring 51 in the current state and the bottom of the containing space.

[0106] Wherein, the lifting stroke Sx of the gas blocking ring 51=S1-n*S2, S1 is the distance between the gas blocking ring 51 in the maximum stroke state and the bottom of the containing space, and when the gas blocking ring 51 is in the maximum stroke state, all the fire outlet channels 30 are in the open state; S2 is the distance between each layer of the fire outlet channel 30. S1 and S2 can be input into the control module in the form of manually measured preset parameters, so as to be called by the control module when making decisions.

[0108] Next, the stove load matching control method provided by the application is further described by taking specific examples.

[0109] In this example, the number of layers of the fire outlet channel 30 of the stove 100 is 6. Before the stove 100 is shipped, the stove 100 needs to be set up first. Different fire outlet loads are matched according to the diameters of different pots 200. For example, the fire outlet loads of different numbers of layers of the fire outlet channel 30 can be set based on pots 200 with diameters of 38 cm, 35 cm, 32 cm, 29 cm, and 26 cm. For example, when the diameter of the pot 200 is greater than 38 cm, the number of layers of the fire outlet channel 30 is 6; when the diameter of the pot 200 is greater than 35 cm and less than or equal to 38 cm, the number of layers of the fire outlet channel 30 is 5; when the diameter of the pot 200 is greater than 32 cm and less than or equal to 35 cm, the number of layers of the fire outlet channel 30 is 4; when the diameter of the pot 200 is greater than 29 cm and less than or equal to 32 cm, the number of layers of the fire outlet channel 30 is 3; when the diameter of the pot 200 is greater than 26 cm and less than or equal to 29 cm, the number of layers of the fire outlet channel 30 is 2; and when the diameter of the pot 200 is less than or equal to 26 cm, the number of layers of the fire outlet channel 30 is 1.

[0110] In the stove 100 load control method described above, the number of layers n of the fire outlet channel 30 that needs to be closed is determined according to the relationship between L, L1, and L2, specifically as follows:
