具体实施方式Detailed ways

下面详细描述本发明的实施例,所述实施例的示例在附图中示出,其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的,仅用于解释本发明,而不能理解为对本发明的限制。Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

下面参考图1-图11描述根据本发明实施例的燃烧器100。The burner 100 according to an embodiment of the present invention will be described below with reference to FIGS. 1 to 11 .

如图1和图2所示,根据本发明实施例的燃烧器100包括分气盘10和火盖组件20,火盖组件20设于分气盘10,并且火盖组件20与分气盘10之间限定出多个分气通道,火盖组件20包括多个环形出火部,多个环形出火部与多个分气通道一一对应地连通。As shown in Figures 1 and 2, the burner 100 according to an embodiment of the present invention includes a gas distribution plate 10 and a fire cover assembly 20. The fire cover assembly 20 is arranged on the gas distribution plate 10, and a plurality of gas distribution channels are defined between the fire cover assembly 20 and the gas distribution plate 10. The fire cover assembly 20 includes a plurality of annular fire outlet portions, and the plurality of annular fire outlet portions are connected to the plurality of gas distribution channels in a one-to-one correspondence.

其中,火盖组件20包括内火盖201和外火盖202,内火盖201和外火盖202均形成环形结构,外火盖202设于内火盖201的外侧,至少两个环形出火部设于内火盖201,内火盖201与外火盖202之间设有热电偶31。Among them, the fire cover assembly 20 includes an inner fire cover 201 and an outer fire cover 202. The inner fire cover 201 and the outer fire cover 202 both form an annular structure. The outer fire cover 202 is arranged on the outside of the inner fire cover 201. At least two annular fire outlets are arranged on the inner fire cover 201. A thermocouple 31 is arranged between the inner fire cover 201 and the outer fire cover 202.

需要说明的是,热电偶31是提供熄火保护的元件,在工作时,当热电偶31的头部被燃烧火焰加热,其产生热电势以给电磁阀供电,从而使燃气通路打开,保证燃气供应,当热电偶31的温度没有达到预定温度,电磁阀没有足够的热电势维持而使燃气通路关闭,从而切断气源。It should be noted that the thermocouple 31 is an element that provides flameout protection. When in operation, when the head of the thermocouple 31 is heated by the burning flame, it generates a thermoelectric potential to power the solenoid valve, thereby opening the gas passage and ensuring the gas supply. When the temperature of the thermocouple 31 does not reach the predetermined temperature, the solenoid valve does not have sufficient thermoelectric potential to maintain the gas passage and closes the gas passage, thereby cutting off the gas source.

根据本发明实施例的燃烧器100,内火盖201可以形成至少内外双侧出火结构,燃气和空气的混合气可以在内火盖201的上表面内均匀分布,保证火焰的充满度,从而保证烹饪过程中烹饪器具可以实现均匀受热,提升烹饪效果。According to the burner 100 of the embodiment of the present invention, the inner fire cover 201 can form at least an inner and outer double-sided fire outlet structure, and the mixture of gas and air can be evenly distributed on the upper surface of the inner fire cover 201 to ensure the fullness of the flame, thereby ensuring that the cooking utensils can be evenly heated during the cooking process and improving the cooking effect.

此外,通过将热电偶31设在内火盖201与外火盖202之间,不仅能保证小负荷工况下的燃烧稳定性,避免熄火延迟,而且可以利用内火盖201或者外火盖202对热电偶31进行定位,提高热电偶31的安装可靠性。In addition, by arranging the thermocouple 31 between the inner fire cover 201 and the outer fire cover 202, not only can the combustion stability under low load conditions be ensured and the flameout delay be avoided, but the inner fire cover 201 or the outer fire cover 202 can also be used to position the thermocouple 31, thereby improving the installation reliability of the thermocouple 31.

如图2所示,根据本发明的一些实施例,分气盘10具有限位凹部123,热电偶31与限位凹部123配合。通过设置限位凹部123,可以限定热电偶31的位置,进一步保证热电偶31的安装可靠性。As shown in Fig. 2, according to some embodiments of the present invention, the gas distribution plate 10 has a limiting recess 123, and the thermocouple 31 cooperates with the limiting recess 123. By providing the limiting recess 123, the position of the thermocouple 31 can be limited, further ensuring the installation reliability of the thermocouple 31.

在一些实施例中,燃烧器100还包括炉头组件30,热电偶31安装在炉头组件30上,因此,通过将热电偶31与分气盘10上的限位凹部123配合,便于根据限位凹部123的位置确定分气盘10和炉头组件30的相对位置,进而便于实现炉头组件30和分气盘10的对接,避免炉头组件30和分气盘10发生错位,避免炉头组件30内的燃气发生泄露,避免造成安全隐患。In some embodiments, the burner 100 also includes a burner head assembly 30, and a thermocouple 31 is installed on the burner head assembly 30. Therefore, by cooperating the thermocouple 31 with the limiting recess 123 on the gas distribution plate 10, it is convenient to determine the relative position of the gas distribution plate 10 and the burner head assembly 30 according to the position of the limiting recess 123, thereby facilitating the docking of the burner head assembly 30 and the gas distribution plate 10, avoiding misalignment of the burner head assembly 30 and the gas distribution plate 10, avoiding leakage of gas in the burner head assembly 30, and avoiding safety hazards.

其中,如图3和图4所示,分气盘10包括分气座121和分气盖122,分气盖122设在分气座121上,限位凹部123可以设置在分气座121和/或分气盖122。As shown in FIG. 3 and FIG. 4 , the gas distributor plate 10 includes a gas distributor seat 121 and a gas distributor cover 122 . The gas distributor cover 122 is disposed on the gas distributor seat 121 . The limiting recess 123 can be disposed on the gas distributor seat 121 and/or the gas distributor cover 122 .

如图3所示,根据本发明的一些实施例,多个环形出火部包括第一环形出火部、第二环形出火部和第三环形出火部,第一环形出火部和第二环形出火部设于内火盖201,并且第二环形出火部位于第一环形出火部的外侧,第三环形出火部设于外火盖202,并且第三环形出火部位于第二环形出火部的外侧,热电偶31位于第二环形出火部与第三环形出火部之间,保证小负荷工况下的燃烧稳定性。As shown in Figure 3, according to some embodiments of the present invention, the plurality of annular fire portions include a first annular fire portion, a second annular fire portion and a third annular fire portion, the first annular fire portion and the second annular fire portion are arranged on the inner fire cover 201, and the second annular fire portion is located on the outside of the first annular fire portion, the third annular fire portion is arranged on the outer fire cover 202, and the third annular fire portion is located on the outside of the second annular fire portion, and the thermocouple 31 is located between the second annular fire portion and the third annular fire portion to ensure combustion stability under low load conditions.

如图4所示,在一些实施例中,多个分气通道包括第一环形分气通道101、第二环形分气通道102和第三环形分气通道103,第一环形分气通道101与第一环形出火部位置对应且连通,第二环形分气通道102与第二环形出火部位置对应且连通,第三环形分气通道103与第三环形出火部位置对应且连通。As shown in Figure 4, in some embodiments, the plurality of air distribution channels include a first annular air distribution channel 101, a second annular air distribution channel 102 and a third annular air distribution channel 103. The first annular air distribution channel 101 corresponds to and is connected with the first annular fire outlet portion, the second annular air distribution channel 102 corresponds to and is connected with the second annular fire outlet portion, and the third annular air distribution channel 103 corresponds to and is connected with the third annular fire outlet portion.

也就是说,第一环形分气通道101、第二环形分气通道102和第三环形分气通道103从内至外依次排布,使第一环形分气通道101形成内环分气通道,使第二环形分气通道102形成中环分气通道,使第三环形分气通道103形成外环分气通道。That is to say, the first annular air dividing channel 101, the second annular air dividing channel 102 and the third annular air dividing channel 103 are arranged in sequence from the inside to the outside, so that the first annular air dividing channel 101 forms an inner ring air dividing channel, the second annular air dividing channel 102 forms a middle ring air dividing channel, and the third annular air dividing channel 103 forms an outer ring air dividing channel.

其中,分气盘10具有第一进气部111和第二进气部112,第一进气部111与第一环形分气通道101连通,第二进气部112与第二环形分气通道102连通,第二进气部112与第三环形分气通道103可以通过过流通道(图中未示出)连通。Among them, the gas distribution disk 10 has a first air inlet part 111 and a second air inlet part 112. The first air inlet part 111 is connected to the first annular air distribution channel 101, and the second air inlet part 112 is connected to the second annular air distribution channel 102. The second air inlet part 112 is connected to the third annular air distribution channel 103 through a flow channel (not shown in the figure).

燃气与空气的混合气可以分别从第一进气部111和第二进气部112进入分气盘10,从第一进气部111进入的混合气可以沿着第一环形分气通道101流动,从而流动至指定区域。The mixture of gas and air can enter the gas distribution plate 10 from the first gas inlet 111 and the second gas inlet 112 respectively. The mixture entering from the first gas inlet 111 can flow along the first annular gas distribution channel 101 and thus flow to the designated area.

从第二进气部112进入的混合气的一部分可以沿着第二环形分气通道102流动,从而流动至指定区域,从第二进气部112进入的混合气的另一部分可以沿着过流通道流动,进入第三环形分气通道103,从而流动至指定区域。也可以是,从第二进气部112进入的混合气进入到第三环形分气通道103,,从而流动至指定区域,而第三环形分气通道103中的一部分混合气可以沿着过流通道流动至第二环形分气通道102,从而流动至指定区域。A portion of the mixed gas entering from the second air intake portion 112 can flow along the second annular air distribution channel 102, thereby flowing to the designated area, and another portion of the mixed gas entering from the second air intake portion 112 can flow along the flow passage and enter the third annular air distribution channel 103, thereby flowing to the designated area. Alternatively, the mixed gas entering from the second air intake portion 112 enters the third annular air distribution channel 103, thereby flowing to the designated area, and a portion of the mixed gas in the third annular air distribution channel 103 can flow along the flow passage to the second annular air distribution channel 102, thereby flowing to the designated area.

与相关技术相比,通过设置第一环形分气通道101、第二环形分气通道102和第三环形分气通道103,利用过流通道连通第二环形分气通道102和第三环形分气通道103,在不增加炉头组件30的引射通道的数量的基础上,使得燃气和空气的混合气可以通过第一进气部111和第二进气部112流动至第一环形分气通道101、第二环形分气通道102和第三环形分气通道103,从而在整个平面范围内均匀分布,保证烹饪过程中烹饪器具可以实现均匀受热,提升烹饪效果。Compared with the related art, by setting the first annular air distribution channel 101, the second annular air distribution channel 102 and the third annular air distribution channel 103, the second annular air distribution channel 102 and the third annular air distribution channel 103 are connected by the flow channel, and the number of injection channels of the burner head assembly 30 is not increased. The mixture of gas and air can flow to the first annular air distribution channel 101, the second annular air distribution channel 102 and the third annular air distribution channel 103 through the first air inlet part 111 and the second air inlet part 112, so as to be evenly distributed in the entire plane range, thereby ensuring that the cooking utensils can be evenly heated during the cooking process and improving the cooking effect.

在一些实施例中,分气盘10包括分气座121和分气盖122,分气盖122设于在分气座121上,分气盖122与火盖组件20之间限定出第一环形分气通道101和第二环形分气通道102,分气座121、分气盖122的外周壁与火盖组件20之间限定出第三环形分气通道103。In some embodiments, the gas distribution plate 10 includes a gas distribution seat 121 and a gas distribution cover 122. The gas distribution cover 122 is arranged on the gas distribution seat 121. A first annular gas distribution channel 101 and a second annular gas distribution channel 102 are defined between the gas distribution cover 122 and the fire cover assembly 20. A third annular gas distribution channel 103 is defined between the outer peripheral walls of the gas distribution seat 121 and the gas distribution cover 122 and the fire cover assembly 20.

分气盘10的结构简单,加工、成型容易,将分气盘10设置成上述结构,利用分气盘10与火盖组件20的结构,可以限定出第一环形分气通道101、第二环形分气通道102和第三环形分气通道103,从而保证混合气分布的均匀性,进一步保证烹饪过程中烹饪器具可以实现均匀受热,提升烹饪效果。The gas distribution plate 10 has a simple structure and is easy to process and form. The gas distribution plate 10 is set to the above structure. By utilizing the structure of the gas distribution plate 10 and the fire cover assembly 20, a first annular gas distribution channel 101, a second annular gas distribution channel 102 and a third annular gas distribution channel 103 can be defined, thereby ensuring the uniformity of the distribution of the mixed gas, further ensuring that the cooking utensils can be evenly heated during the cooking process, and improving the cooking effect.

在一些具体实施例中,分气盖122上设有多个过气部1220,多个过气部1220连通第二进气部112和第二环形分气通道102,多个过气部1220沿第二环形分气通道102的周向间隔排布。In some specific embodiments, the gas separation cover 122 is provided with a plurality of gas passages 1220 , which connect the second air inlet 112 and the second annular gas separation channel 102 , and are arranged at intervals along the circumference of the second annular gas separation channel 102 .

由此,通过设置多个过气部1220,可以从多个过气部1220进入到第二环形分气通道102,不仅可以增加单位时间内第二环形分气通道102的进气量,提升混合气进入第二环形分气通道102的效率,而且可以保证混合气在第二环形分气通道102内分布的均匀性,进一步保证烹饪过程中烹饪器具可以实现均匀受热,提升烹饪效果。Therefore, by setting up multiple air passages 1220, the air can enter the second annular air distribution channel 102 from the multiple air passages 1220, which not only can increase the air intake volume of the second annular air distribution channel 102 per unit time and improve the efficiency of the mixed gas entering the second annular air distribution channel 102, but also can ensure the uniformity of the distribution of the mixed gas in the second annular air distribution channel 102, further ensure that the cooking utensils can be evenly heated during the cooking process, and improve the cooking effect.

在一些示例中,过气部1220包括第一过气孔,第一过气孔形成沿第二进气部112的周向延伸的条形孔,加工容易,并且可以保证单位时间内的过气量,从而提高过气效率。In some examples, the air passage portion 1220 includes a first air passage hole, which is formed into a strip hole extending along the circumference of the second air inlet portion 112, is easy to process, and can ensure the amount of air passing per unit time, thereby improving the air passing efficiency.

在一些示例中,过气部1220包括多个第二过气孔,多个第二过气孔在第二进气部112的周向间隔排布,可以增加第二过气孔的数量,使燃气与空气充分混合,进一步保证混合气在第二环形分气通道102内分布的均匀性,从而保证烹饪过程中烹饪器具可以实现均匀受热,提升烹饪效果。其中,第二过气孔可以为圆孔、方孔等。In some examples, the air passage portion 1220 includes a plurality of second air passage holes, which are arranged at intervals in the circumferential direction of the second air inlet portion 112, and the number of second air passage holes can be increased to fully mix the gas and the air, and further ensure the uniformity of the mixed gas distribution in the second annular gas distribution channel 102, thereby ensuring that the cooking utensils can be evenly heated during the cooking process and improving the cooking effect. The second air passage holes can be round holes, square holes, etc.

在一些示例中,每个过气部1220的通流面积从第二进气部112至第二环形分气通道102渐扩。也就是说,过气部1220的通流面积沿混合气的流动方向逐渐增大。In some examples, the flow area of each air passage 1220 gradually expands from the second air inlet 112 to the second annular air splitting channel 102. In other words, the flow area of the air passage 1220 gradually increases along the flow direction of the mixed gas.

具体地,从第二进气部112进入的混合气,一部分可以朝上流动,从而通过多个过气部1220进入第二环形分气通道102,另一部分沿着过流通道朝第三环形分气通道103流动。Specifically, a portion of the mixed gas entering from the second air inlet portion 112 may flow upward and enter the second annular air distribution channel 102 through the plurality of air passing portions 1220 , and another portion may flow along the flow passage toward the third annular air distribution channel 103 .

由于过气部1220的通流面积从第二进气部112至第二环形分气通道102渐扩,可以将经过该位置的混合气增压、降速,从而提高混合气在第二进气部112与过气部1220之间的空间的充满度,最终使混合气在第二环形分气通道102内分配均匀,还可以更有效地分割第二环形分气通道102和第三环形分气通道103的混气量,进一步地保证混合气在整个平面范围内均匀分布,保证烹饪过程中烹饪器具可以实现均匀受热,提升烹饪效果。Since the flow area of the air passage 1220 gradually expands from the second air inlet 112 to the second annular air distribution channel 102, the mixed gas passing through this position can be pressurized and decelerated, thereby increasing the fullness of the space between the second air inlet 112 and the air passage 1220, and ultimately making the mixed gas evenly distributed in the second annular air distribution channel 102. It can also more effectively divide the mixed gas volume of the second annular air distribution channel 102 and the third annular air distribution channel 103, further ensuring that the mixed gas is evenly distributed in the entire plane range, ensuring that the cooking utensils can be evenly heated during the cooking process, and improving the cooking effect.

在一些具体实施例,分气盘10具有多个通风口113,多个通风口113位于第二环形分气通道102和第三环形分气通道103之间,多个通风口113在第二环形分气通道102的周向间隔布置,热电偶31位于其中一个通风口113内。环境中的空气可在多个通风口113处流动,通风口113处的空气不仅能够为燃气补充空气,以使燃气能够充分的燃烧,而且可以为热电偶31提供安装空间,从而提高空间利用率。In some specific embodiments, the gas distribution plate 10 has a plurality of vents 113, the plurality of vents 113 are located between the second annular gas distribution channel 102 and the third annular gas distribution channel 103, the plurality of vents 113 are arranged at intervals in the circumferential direction of the second annular gas distribution channel 102, and the thermocouple 31 is located in one of the vents 113. The air in the environment can flow through the plurality of vents 113, and the air at the vents 113 can not only supplement air for the gas so that the gas can be fully burned, but also provide installation space for the thermocouple 31, thereby improving space utilization.

在热电偶31与分气盘10上的限位凹部123配合的实施例中,限位凹部123位于通风口113内。In the embodiment where the thermocouple 31 cooperates with the limiting recess 123 on the gas distribution plate 10 , the limiting recess 123 is located in the vent 113 .

在一些具体实施例,分气盘10自身或者分气盘10与火盖组件20之间限定出多个过流通道,多个过流通道位于第二环形分气通道102和第三环形分气通道103之间,并且多个过流通道在第二环形分气通道102的周向间隔布置,每个过流通道连通第二环形分气通道102和第三环形分气通道103,以使燃气能够在第二环形分气通道102、分气通道和第三环形分气通道103内均匀的流动,避免燃气会聚集在第二环形分气通道102或第三环形分气通道103内。In some specific embodiments, a plurality of flow channels are defined by the gas distribution plate 10 itself or between the gas distribution plate 10 and the fire cover assembly 20, and the plurality of flow channels are located between the second annular gas distribution channel 102 and the third annular gas distribution channel 103, and the plurality of flow channels are arranged at circumferential intervals in the second annular gas distribution channel 102, and each flow channel connects the second annular gas distribution channel 102 and the third annular gas distribution channel 103, so that the gas can flow evenly in the second annular gas distribution channel 102, the gas distribution channel and the third annular gas distribution channel 103, thereby preventing the gas from gathering in the second annular gas distribution channel 102 or the third annular gas distribution channel 103.

通过设置多个过流通道,不仅可以提升混合气的流动效率,而且可以保证混合气分布的均匀性,进一步保证烹饪过程中烹饪器具可以实现均匀受热,提升烹饪效果。其中,热电偶31位于其中两个过流通道之间,避免热电偶31与过流通道形成干涉。By setting up multiple flow channels, not only can the flow efficiency of the mixed gas be improved, but also the uniformity of the distribution of the mixed gas can be ensured, further ensuring that the cooking utensils can be evenly heated during the cooking process, thereby improving the cooking effect. The thermocouple 31 is located between two of the flow channels to avoid interference between the thermocouple 31 and the flow channels.

在一些实施例中,炉头组件30具有第一引射通道、第二引射通道、第一混气腔和第二混气腔,第一混气腔连通第一进气部111和第一引射通道,第二混气腔连通第二进气部112和第二引射通道。In some embodiments, the furnace head assembly 30 has a first ejection channel, a second ejection channel, a first gas mixing chamber and a second gas mixing chamber. The first gas mixing chamber connects the first air inlet 111 and the first ejection channel, and the second gas mixing chamber connects the second air inlet 112 and the second ejection channel.

通过控制第一引射通道和第二引射通道内的燃气能够对火盖组件20上方的火焰进行控制,具体地,第一引射通道内的混合气可以依次流经第一混合腔、第一进气部111、第一环形分气通道101、位于内侧的环形出火部,第一引射通道内的混合气可以依次流经第二混合腔、第二进气部112,一部分混合气流动至第二环形分气通道102,最终从第二环形出火部流出,一部分混合气沿着过流通道流动至第三环形分气通道103,最终从第三环形出火部流出。By controlling the gas in the first injection channel and the second injection channel, the flame above the fire cover assembly 20 can be controlled. Specifically, the mixed gas in the first injection channel can flow through the first mixing chamber, the first air inlet portion 111, the first annular air distribution channel 101, and the inner annular fire outlet portion in sequence; the mixed gas in the first injection channel can flow through the second mixing chamber and the second air inlet portion 112 in sequence; a portion of the mixed gas flows to the second annular air distribution channel 102 and finally flows out from the second annular fire outlet portion; a portion of the mixed gas flows along the flow channel to the third annular air distribution channel 103 and finally flows out from the third annular fire outlet portion.

这样在调节火焰大小时,能够单独控制第一环形出火部处火焰的大小,例如在将燃烧器100产生的火焰从大火调为小火时,能够始终保持第一环形出火部处形成火焰。In this way, when adjusting the flame size, the size of the flame at the first annular fire outlet can be controlled separately. For example, when the flame generated by the burner 100 is adjusted from a high flame to a low flame, the flame formed at the first annular fire outlet can always be maintained.

在用户调节火焰大小时,能够同时调节第二环形出火部和第三环形出火部处的火焰大小,以便于在火盖组件20上方形成均匀的火焰,避免第二环形出火部和第三环形出火部温差过大,影响燃烧器100对烹饪器具的加热,保证烹饪过程中烹饪器具可以实现均匀受热,提升烹饪效果。When the user adjusts the flame size, the flame size at the second annular fire portion and the third annular fire portion can be adjusted at the same time, so as to form a uniform flame above the fire cover assembly 20, avoiding excessive temperature difference between the second annular fire portion and the third annular fire portion, which affects the heating of the cooking utensils by the burner 100, and ensuring that the cooking utensils can be evenly heated during the cooking process, thereby improving the cooking effect.

在一些实施例中,炉头组件30上设有点火件32,炉头组件30可以对点火件32的位置进行固定,使点火件32能够顺利点燃燃气,以能够在火盖组件20上方形成环形火焰。In some embodiments, an ignition element 32 is disposed on the burner head assembly 30 , and the burner head assembly 30 can fix the position of the ignition element 32 so that the ignition element 32 can smoothly ignite the gas to form a ring-shaped flame above the fire cover assembly 20 .

其中,点火件32设于内火盖201与外火盖202之间,以能够点燃内火盖201或外火盖202上方的燃气,进而在内火盖201或外火盖202上方形成火焰。The ignition element 32 is disposed between the inner fire cover 201 and the outer fire cover 202 so as to ignite the gas above the inner fire cover 201 or the outer fire cover 202 , thereby forming a flame above the inner fire cover 201 or the outer fire cover 202 .

如图5-图11所示,根据本发明进一步的实施例,内火盖201的上表面具有第一环形出火面2111和第二环形出火面2112,第二环形出火面2112设于第一环形出火面2111的外侧,第一环形出火部设于第一环形出火面2111,第二环形出火部设于第二环形出火面2112。As shown in Figures 5-11, according to a further embodiment of the present invention, the upper surface of the inner fire cover 201 has a first annular fire surface 2111 and a second annular fire surface 2112, the second annular fire surface 2112 is arranged on the outside of the first annular fire surface 2111, the first annular fire portion is arranged on the first annular fire surface 2111, and the second annular fire portion is arranged on the second annular fire surface 2112.

其中,第一环形出火部包括多个间隔布置的第一主火孔2101,多个第一主火孔2101与第一环形分气通道101连通,第二环形出火部包括多个间隔布置的第二主火孔2102,多个第二主火孔2102与第二环形分气通道102连通。Among them, the first annular fire portion includes a plurality of first main fire holes 2101 arranged at intervals, and the plurality of first main fire holes 2101 are connected to the first annular gas distribution channel 101; the second annular fire portion includes a plurality of second main fire holes 2102 arranged at intervals, and the plurality of second main fire holes 2102 are connected to the second annular gas distribution channel 102.

由此,通过在第一环形出火面2111上设置多个第一主火孔2101,在第二环形出火面2112上设置多个第二主火孔2102,使内火盖201形成内外双侧出火结构,燃气和空气的混合气从多个第一主火孔2101和多个第二主火孔2102流出,可以在内火盖201的上表面内均匀分布,保证火焰的充满度,从而保证烹饪过程中烹饪器具可以实现均匀受热,提升烹饪效果。Therefore, by arranging a plurality of first main fire holes 2101 on the first annular fire surface 2111 and a plurality of second main fire holes 2102 on the second annular fire surface 2112, the inner fire cover 201 forms an inner and outer double-sided fire structure, and a mixture of gas and air flows out from the plurality of first main fire holes 2101 and the plurality of second main fire holes 2102, and can be evenly distributed on the upper surface of the inner fire cover 201, thereby ensuring the fullness of the flame, thereby ensuring that the cooking utensils can be evenly heated during the cooking process, thereby improving the cooking effect.

进一步地,第三环形出火部包括多个第三主火孔2021,多个第三主火孔2021在外火盖202的周向间隔布置,第三主火孔2021处的燃气燃烧可以形成第三主火焰(外侧火焰)。Furthermore, the third annular fire outlet portion includes a plurality of third main fire holes 2021 , which are arranged at intervals in the circumferential direction of the outer fire cover 202 , and the combustion of gas at the third main fire holes 2021 can form a third main flame (outer flame).

在一些实施例中,多个第一主火孔2101在第一环形出火面2111的周向和径向上间隔排布。将多个第一主火孔2101如此布置,可以增加第一主火孔2101的分布面积,从而可以扩大出火范围,进一步保证火焰的充满度,使烹饪器具可以实现均匀受热,提升烹饪效果。In some embodiments, a plurality of first main fire holes 2101 are arranged at intervals in the circumferential and radial directions of the first annular fire outlet surface 2111. Arranging the plurality of first main fire holes 2101 in this way can increase the distribution area of the first main fire holes 2101, thereby expanding the fire outlet range, further ensuring the fullness of the flame, allowing the cooking utensil to be evenly heated, and improving the cooking effect.

在一些实施例中,多个第二主火孔2102在第二环形出火面2112的周向间隔排布。将多个第二主火孔2102如此布置,可以保证火焰在内火盖201的周向上的充满度,进一步使烹饪器具可以实现均匀受热,提升烹饪效果。In some embodiments, a plurality of second main fire holes 2102 are arranged at intervals in the circumferential direction of the second annular fire outlet surface 2112. Arranging the plurality of second main fire holes 2102 in this way can ensure that the flame is full in the circumferential direction of the inner fire cover 201, further allowing the cooking utensil to be heated evenly and improving the cooking effect.

如图5和图6所示,第二主火孔2102的尺寸大于第一主火孔2101的尺寸。As shown in FIGS. 5 and 6 , the size of the second main fire hole 2102 is larger than the size of the first main fire hole 2101 .

由于第一环形出火面2111上的第一主火孔2101的数量较多,并且多个第一主火孔2101的分布面积较大,第二环形出火面2112上的第二主火孔2102的数量较少,多个第二主火孔2102的分布面积较小。Since there are more first main fire holes 2101 on the first annular fire surface 2111 and the distribution area of the multiple first main fire holes 2101 is larger, there are fewer second main fire holes 2102 on the second annular fire surface 2112 and the distribution area of the multiple second main fire holes 2102 is smaller.

因此,通过将第二主火孔2102的尺寸设置为大于第一主火孔2101的尺寸,使混合气在第一环形出火面2111和第二环形出火面2112均匀地尽量分布,保证烹饪过程中烹饪器具可以实现均匀受热,提升烹饪效果。Therefore, by setting the size of the second main fire hole 2102 to be larger than that of the first main fire hole 2101, the mixed gas can be distributed as evenly as possible on the first annular fire surface 2111 and the second annular fire surface 2112, ensuring that the cooking utensils can be evenly heated during the cooking process, thereby improving the cooking effect.

其中,第一主火孔2101和/或第二主火孔2102为圆孔或者条形孔。Among them, the first main fire hole 2101 and/or the second main fire hole 2102 are circular holes or strip holes.

具体地,可以是,第一主火孔2101和第二主火孔2102均为圆孔;也可以是,第一主火孔2101和第二主火孔2102均为条形孔;还可以是,第一主火孔2101为圆孔,第二主火孔2102为条形孔;或者,第一主火孔2101为条形孔,第二主火孔2102为圆孔。Specifically, the first main fire hole 2101 and the second main fire hole 2102 may both be round holes; or the first main fire hole 2101 and the second main fire hole 2102 may both be strip holes; or the first main fire hole 2101 may be a round hole and the second main fire hole 2102 may be a strip hole; or the first main fire hole 2101 may be a strip hole and the second main fire hole 2102 may be a round hole.

需要说明的是,第一主火孔2101和第二主火孔2102的形状不限于圆孔或者条形孔,并且第一主火孔2101和第二主火孔2102的尺寸可以根据需要进行调整,以保证烹饪器具可以实现均匀受热,提升烹饪效果。It should be noted that the shapes of the first main fire hole 2101 and the second main fire hole 2102 are not limited to round holes or strip holes, and the sizes of the first main fire hole 2101 and the second main fire hole 2102 can be adjusted as needed to ensure that the cooking utensils can be heated evenly and improve the cooking effect.

如图7和图8所示,在一些实施例中,第一主火孔2101的轴向沿靠近第一环形出火面2111的中心的方向朝上延伸,第二主火孔2102的轴向沿远离第二环形出火面2112的中心的方向朝上延伸。As shown in Figures 7 and 8, in some embodiments, the axial direction of the first main fire hole 2101 extends upward in a direction close to the center of the first annular fire surface 2111, and the axial direction of the second main fire hole 2102 extends upward in a direction away from the center of the second annular fire surface 2112.

也就是说,在同一纵截面上的第一主火孔2101和第二主火孔2102中,第一主火孔2101和第二主火孔2102沿远离彼此的方向朝上倾斜延伸,第一主火孔2101处的燃气燃烧可以形成第一主火焰(内侧火焰),第二主火孔2102处的燃气燃烧可以形成第二主火焰(中部火焰)。That is to say, in the first main fire hole 2101 and the second main fire hole 2102 on the same longitudinal section, the first main fire hole 2101 and the second main fire hole 2102 extend upwardly and obliquely in a direction away from each other, and the gas combustion at the first main fire hole 2101 can form a first main flame (inner flame), and the gas combustion at the second main fire hole 2102 can form a second main flame (middle flame).

由此,通过将第一主火孔2101和第二主火孔2102如此设置,可以增加形成的内侧火焰和中部火焰的分布面积,可以增加烹饪器具的受热面积,提升烹饪效率。Therefore, by arranging the first main fire hole 2101 and the second main fire hole 2102 in this way, the distribution area of the inner flame and the middle flame formed can be increased, the heating area of the cooking utensil can be increased, and the cooking efficiency can be improved.

在一些实施例中,第一环形出火面2111和第二环形出火面2112沿远离彼此的方向朝下延伸。具体地,如图7和图8所示,第一环形出火面2111从外至内朝下延伸,第二环形出火面2112从内至外朝下延伸。In some embodiments, the first annular fire surface 2111 and the second annular fire surface 2112 extend downwardly in a direction away from each other. Specifically, as shown in Figures 7 and 8, the first annular fire surface 2111 extends downwardly from outside to inside, and the second annular fire surface 2112 extends downwardly from inside to outside.

如此设置,可以增加第一环形出火面2111和第二环形出火面2112的表面面积,从而可以增加第一主火孔2101和第二主火孔2102的总面积,使形成的内侧火焰和中部火焰的分布面积大幅增加,进而可以增加烹饪器具的受热面积,提升烹饪效率。Such a configuration can increase the surface area of the first annular fire surface 2111 and the second annular fire surface 2112, thereby increasing the total area of the first main fire hole 2101 and the second main fire hole 2102, greatly increasing the distribution area of the inner flame and the middle flame formed, thereby increasing the heating area of the cooking utensil and improving cooking efficiency.

如图5所示,在一些实施例中,内火盖201的外周壁设有稳火孔2105,稳火孔2105与第一环形分气通道101连通,热电偶31正对稳火孔2105。通过设置与第一环形分气通道101连通的稳火孔2105,即使只有第一环形出火部形成内侧火焰时,即在最小负荷工况下,热电偶31处依然有火焰维持,使热电偶31在任何工况下均能监测火焰。As shown in Fig. 5, in some embodiments, the outer peripheral wall of the inner fire cover 201 is provided with a flame stabilizing hole 2105, the flame stabilizing hole 2105 is communicated with the first annular gas distribution channel 101, and the thermocouple 31 is directly opposite to the flame stabilizing hole 2105. By providing the flame stabilizing hole 2105 communicated with the first annular gas distribution channel 101, even when only the inner flame is formed in the first annular fire outlet, that is, under the minimum load condition, the flame is still maintained at the thermocouple 31, so that the thermocouple 31 can monitor the flame under any condition.

在一些具体示例中,内火盖201的外周壁设有稳焰槽2104,稳焰槽2104位于第二环形出火部上方,并且稳焰槽2104的开口朝外,稳焰槽2104连通第二环形分气通道102和外界。In some specific examples, a flame stabilizing groove 2104 is provided on the outer peripheral wall of the inner fire cover 201. The flame stabilizing groove 2104 is located above the second annular fire outlet portion, and the opening of the flame stabilizing groove 2104 faces outward. The flame stabilizing groove 2104 connects the second annular gas distribution channel 102 and the outside.

从稳焰槽2104流出的燃气被点燃,可以形成稳焰火,稳焰火可以防止第二环形出火部形成的第二主火焰发生偏流,使第二主火孔2102处的燃气充分燃烧,这样烹饪器具可以实现均匀受热,提升烹饪效果。The gas flowing out of the flame stabilizing groove 2104 is ignited to form a stable flame fire, which can prevent the second main flame formed by the second annular fire outlet from deviating and make the gas at the second main fire hole 2102 burn fully, so that the cooking utensils can be evenly heated and the cooking effect is improved.

在一些具体示例中,第一环形分气通道101的外侧设有连接槽105,连接槽105正对稳火孔2105,连接槽105连通稳焰槽2104和稳火孔2105。即使在最小负荷的工况下,第一环形分气通道101也能为稳焰槽2104提供一定量的燃气,从而形成一定长度的线性稳火焰,来稳住稳火孔2105的火焰,保证在任何负荷的工况下,热电偶31都能监测到火焰。In some specific examples, a connecting groove 105 is provided on the outer side of the first annular gas distribution channel 101, the connecting groove 105 is directly opposite to the flame stabilizing hole 2105, and the connecting groove 105 connects the flame stabilizing groove 2104 and the flame stabilizing hole 2105. Even under the minimum load condition, the first annular gas distribution channel 101 can provide a certain amount of fuel gas to the flame stabilizing groove 2104, thereby forming a linear stable flame of a certain length to stabilize the flame of the flame stabilizing hole 2105, ensuring that the thermocouple 31 can monitor the flame under any load condition.

如图6-图8所示,在一些具体示例中,稳焰槽2104沿内火盖201的周向延伸,稳焰槽2104的槽壁设有多个通气孔2106,多个通气孔2106在稳焰槽2104的延伸方向间隔布置,通气孔2106连通稳焰槽2104和第二环形分气通道102。As shown in Figures 6 to 8, in some specific examples, the flame stabilizing groove 2104 extends along the circumference of the inner fire cover 201, and the groove wall of the flame stabilizing groove 2104 is provided with a plurality of air holes 2106, and the plurality of air holes 2106 are arranged at intervals in the extension direction of the flame stabilizing groove 2104, and the air holes 2106 connect the flame stabilizing groove 2104 and the second annular gas distribution channel 102.

具体地,第二环形分气通道102中的一部分混合气可以从多个第二主火孔2102流出,可以形成第二主火焰,一部分混合气经过多个通气孔2106流动至稳焰槽2104内,可以形成稳焰火,稳焰火可以防止第二主火孔2102形成的第二主火焰发生偏流,使第二主火孔2102处的燃气充分燃烧,使烹饪器具可以实现均匀受热,提升烹饪效果。Specifically, a portion of the mixed gas in the second annular gas distribution channel 102 can flow out from the multiple second main fire holes 2102 to form a second main flame, and a portion of the mixed gas can flow into the flame stabilizing groove 2104 through the multiple ventilation holes 2106 to form a stable flame fire. The stable flame fire can prevent the second main flame formed by the second main fire hole 2102 from deviating, so that the gas at the second main fire hole 2102 can be fully burned, so that the cooking utensils can be evenly heated, thereby improving the cooking effect.

如图5、图8和图11所示,在一些具体示例中,内火盖201的顶部具有传火槽2107,传火槽2107连通稳焰槽2104和第一环形出火部,即传火槽2107连通稳焰槽2104和第一主火孔2101。As shown in Figures 5, 8 and 11, in some specific examples, the top of the inner fire cover 201 has a fire transfer groove 2107, and the fire transfer groove 2107 connects the flame stabilizing groove 2104 and the first annular fire outlet, that is, the fire transfer groove 2107 connects the flame stabilizing groove 2104 and the first main fire hole 2101.

点火件32点火时,第二主火孔2102形成的第二主火焰(中部火焰)可以向内传递,中部火焰可以快速地将多个第一主火孔2101流出的燃气点燃,提升烹饪效率。When the ignition element 32 is ignited, the second main flame (middle flame) formed by the second main fire hole 2102 can be transmitted inward, and the middle flame can quickly ignite the gas flowing out of multiple first main fire holes 2101, thereby improving cooking efficiency.

当用户将燃气的火力调小到只剩下第一环形出火部有燃气时,只有内火盖201的第一环形出火部可以形成火焰,而内火盖201的第二环形出火部无法形成火焰。此时,为了避免热电偶因未能感受到火焰而自动关闭燃气开关,导致用户不能在小火力时持续用火,通过设置传火槽2107,可以使第一环形出火部形成的火焰沿着传火槽2107传火给热电偶所在的位置,保证热电偶感受到出火,使热电偶不做出关闭燃气开关的自动保护操作。When the user reduces the power of the gas to only the first annular fire outlet with gas, only the first annular fire outlet of the inner fire cover 201 can form a flame, while the second annular fire outlet of the inner fire cover 201 cannot form a flame. At this time, in order to prevent the thermocouple from automatically turning off the gas switch due to failure to sense the flame, resulting in the user being unable to continue using the fire at a low power, by providing the flame transfer groove 2107, the flame formed by the first annular fire outlet can be transferred to the position of the thermocouple along the flame transfer groove 2107, ensuring that the thermocouple senses the flame and prevents the thermocouple from performing the automatic protection operation of turning off the gas switch.

在一些实施例中,传火槽2107的一端与第一环形出火部连通,传火槽2107的另一端朝内火盖201的外周壁延伸,多个稳火孔2105在传火槽2107的周向上间隔布置。In some embodiments, one end of the fire transfer groove 2107 is connected to the first annular fire outlet, and the other end of the fire transfer groove 2107 extends toward the outer peripheral wall of the inner fire cover 201 , and a plurality of fire stabilizing holes 2105 are arranged at intervals in the circumferential direction of the fire transfer groove 2107 .

在任何负荷工况下,传火槽2107均能够连接第一环形出火部形成的内侧火焰和稳火孔2105形成的火焰,使稳火孔2105形成的火焰始终保持稳定,不离焰。Under any load condition, the flame transfer groove 2107 can connect the inner flame formed by the first annular fire outlet and the flame formed by the fire stabilizing hole 2105, so that the flame formed by the fire stabilizing hole 2105 always remains stable and does not separate.

如图1所示,传火槽2107贯通内火盖201的壁以连通第一环形分气通道101与内火盖201的上方空间,第一环形分气通道101内的混合气可以从传火槽2107流出,从而在传火槽2107处形成火焰,进一步保证热电偶即使是在小火力工况也可以感受到出火,使热电偶不做出关闭燃气开关的自动保护操作。As shown in Figure 1, the fire transfer groove 2107 passes through the wall of the inner fire cover 201 to connect the first annular gas distribution channel 101 with the space above the inner fire cover 201. The mixed gas in the first annular gas distribution channel 101 can flow out from the fire transfer groove 2107, thereby forming a flame at the fire transfer groove 2107, further ensuring that the thermocouple can sense the fire even under low-fire conditions, so that the thermocouple does not perform the automatic protection operation of closing the gas switch.

其中,传火槽2107在垂直于内火盖201轴向的平面内的投影沿内火盖201的径向延伸,尽可能地减短传火槽2107的延伸长度,保证热电偶感受火焰的灵敏度。The projection of the fire transfer groove 2107 in a plane perpendicular to the axial direction of the inner fire cover 201 extends radially along the inner fire cover 201, and the extension length of the fire transfer groove 2107 is shortened as much as possible to ensure the sensitivity of the thermocouple to the flame.

在一些具体示例中,内火盖201还设有多个稳焰孔2103,多个稳焰孔2103在内火盖201的周向间隔排布,稳焰孔2103与第二环形分气通道连通,第二环形出火部包括多个间隔布置的第二主火孔2102,稳焰孔2103位于相邻两个第二主火孔2102之间。In some specific examples, the inner fire cover 201 is also provided with a plurality of flame stabilizing holes 2103, which are arranged at intervals in the circumferential direction of the inner fire cover 201, and the flame stabilizing holes 2103 are connected to the second annular gas distribution channel, and the second annular fire outlet portion includes a plurality of second main fire holes 2102 arranged at intervals, and the flame stabilizing holes 2103 are located between two adjacent second main fire holes 2102.

具体地,燃气和空气的混合气从多个第一主火孔2101流出,可以形成第一主火焰,燃气和空气的混合气从多个第二主火孔2102流出,可以形成第二主火焰,燃气和空气的混合气从多个稳焰孔2103流出,可以形成稳焰火,稳焰火可以防止第二主火焰发生偏流,使第二主火孔2102处的燃气充分燃烧,使烹饪器具可以实现均匀受热,提升烹饪效果。Specifically, a mixture of gas and air flows out from multiple first main fire holes 2101 to form a first main flame, a mixture of gas and air flows out from multiple second main fire holes 2102 to form a second main flame, and a mixture of gas and air flows out from multiple stabilizing flame holes 2103 to form a stable flame fire. The stable flame fire can prevent the second main flame from deviating, so that the gas at the second main fire holes 2102 can be fully burned, so that the cooking utensils can be evenly heated, thereby improving the cooking effect.

其中,稳焰孔2103的尺寸小于第二主火孔2102的尺寸。Among them, the size of the flame stabilizing hole 2103 is smaller than the size of the second main fire hole 2102.

在一些示例中,多个第二主火孔2102和多个稳焰孔2103可以排布组合形成多个火孔组,多个火孔组在第二环形出火面2112的周向间隔布置,每个火孔组包括两个第二主火孔2102、位于该两个第二主火孔2102之间的稳焰孔2103。In some examples, multiple second main fire holes 2102 and multiple flame stabilizing holes 2103 can be arranged and combined to form multiple fire hole groups, and the multiple fire hole groups are arranged at circumferential intervals on the second annular fire outlet surface 2112, and each fire hole group includes two second main fire holes 2102 and a flame stabilizing hole 2103 located between the two second main fire holes 2102.

如图7和图8所示,在一些具体示例中,内火盖201包括第一顶板211、第一环形围板212、第二环形围板213和第三环形围板214,第一环形出火部和第二环形出火部设于第一顶板211,第一环形围板212的上端与第一顶板211连接,第二环形围板213的上端与第一顶板211连接,并且第二环形围板213位于第一环形围板212的外侧,第三环形围板214的上端与第一顶板211连接,并且第三环形围板214位于第一环形围板212与第二环形围板213之间,第一环形围板212、第三环形围板214和第一顶板211之间限定出第一环形分气通道101的一部分,第二环形围板213、第三环形围板214和第一顶板211之间限定出第二环形分气通道102的一部分。As shown in Figures 7 and 8, in some specific examples, the inner fire cover 201 includes a first top plate 211, a first annular enclosure plate 212, a second annular enclosure plate 213 and a third annular enclosure plate 214, the first annular fire outlet portion and the second annular fire outlet portion are arranged on the first top plate 211, the upper end of the first annular enclosure plate 212 is connected to the first top plate 211, the upper end of the second annular enclosure plate 213 is connected to the first top plate 211, and the second annular enclosure plate 213 is located on the outside of the first annular enclosure plate 212, the upper end of the third annular enclosure plate 214 is connected to the first top plate 211, and the third annular enclosure plate 214 is located between the first annular enclosure plate 212 and the second annular enclosure plate 213, a part of the first annular gas distribution channel 101 is defined between the first annular enclosure plate 212, the third annular enclosure plate 214 and the first top plate 211, and a part of the second annular gas distribution channel 102 is defined between the second annular enclosure plate 213, the third annular enclosure plate 214 and the first top plate 211.

其中,第一环形分气通道101与第一主火孔2101连通,第二环形分气通道102与第二主火孔2102连通,一部分混合气可以进入第一环形分气通道101,从多个第一主火孔2101流出,形成内侧火焰,另一部分混合气可以进入第一环形分气通道101,从多个第二主火孔2102流出,形成中部火焰。Among them, the first annular gas distribution channel 101 is connected to the first main fire hole 2101, and the second annular gas distribution channel 102 is connected to the second main fire hole 2102. A part of the mixed gas can enter the first annular gas distribution channel 101 and flow out from multiple first main fire holes 2101 to form an inner flame, and another part of the mixed gas can enter the first annular gas distribution channel 101 and flow out from multiple second main fire holes 2102 to form a middle flame.

由此,通过在第一环形围板212与第二环形围板213之间设置第三环形围板214,可以限定出相互不连通的第一环形分气通道101和第二环形分气通道102,可以与分气盘10上的至少两个环形分气腔对应连通,利于单独控制各通道的燃气量。Therefore, by setting the third annular enclosure plate 214 between the first annular enclosure plate 212 and the second annular enclosure plate 213, the first annular gas distribution channel 101 and the second annular gas distribution channel 102 that are not connected to each other can be defined, and can be connected to at least two annular gas distribution cavities on the gas distribution plate 10 accordingly, which is conducive to individually controlling the gas volume of each channel.

具体地,第一顶板211的上表面具有环形配合面2113,环形配合面2113位于第一环形出火部与第二环形出火部之间,内火盖201还包括第二顶板22,第二顶板22设于环形配合面2113的上方,并且第二顶板22与环形配合面2113之间限定出稳焰槽2104。Specifically, the upper surface of the first top plate 211 has an annular mating surface 2113, which is located between the first annular fire outlet portion and the second annular fire outlet portion. The inner fire cover 201 also includes a second top plate 22, which is arranged above the annular mating surface 2113, and a flame stabilizing groove 2104 is defined between the second top plate 22 and the annular mating surface 2113.

在一些示例中,环形配合面2113上设有多个通气孔2106,多个通气孔2106在环形配合面2113的周向间隔排布,并且通气孔2106连通稳焰槽2104和混气腔。In some examples, a plurality of ventilation holes 2106 are provided on the annular mating surface 2113 , and the plurality of ventilation holes 2106 are arranged at intervals in the circumferential direction of the annular mating surface 2113 , and the ventilation holes 2106 are connected to the flame stabilizing groove 2104 and the gas mixing chamber.

具体地,燃气和空气形成的混合气在混气腔内进一步混合,一部分混合气从多个第二主火孔2102流出,可以形成第二主火焰,一部分混合气经过多个通气孔2106流动至稳焰槽2104内,可以形成稳焰火,稳焰火可以防止第二主火焰发生偏流,使第二主火孔2102处的燃气充分燃烧,使烹饪器具可以实现均匀受热,提升烹饪效果。Specifically, the mixed gas formed by the gas and air is further mixed in the mixing chamber, and a part of the mixed gas flows out from the multiple second main fire holes 2102 to form a second main flame, and a part of the mixed gas flows through the multiple ventilation holes 2106 to the flame stabilizing groove 2104 to form a stable flame. The stable flame can prevent the second main flame from deviating and make the gas at the second main fire hole 2102 fully burn, so that the cooking utensils can be evenly heated and the cooking effect is improved.

其中,第二顶板22的外周沿设有朝外延伸的安装凸耳,安装凸耳上设有点火伞23。The outer circumference of the second top plate 22 is provided with a mounting lug extending outward, and an ignition umbrella 23 is provided on the mounting lug.
