Abstract
Description
Technical Field

[0002] Gas stoves are commonly used kitchen cooking appliances. During the use of the burner, the air supply situation affects the gas combustion efficiency and the energy efficiency level of the gas stove.
[0003] At present, a commonly used burner air supply scheme is to supply primary air naturally through an ejector tube, and supply secondary air to the space around the fire hole, thereby improving the combustion efficiency of the burner through the primary air and secondary air.
[0004] For example, a utility model patent with authorization announcement number CN217402548U discloses a burner, which includes a burner body and a rectifying component. The rectifying component includes a first flow portion, a first flow cavity is provided in the first flow portion, the first flow cavity is located between the inner ring mixing cavity and the outer ring mixing cavity, the rectifying component is provided with a plurality of groups of air holes for connecting the first flow cavity and the outside of the rectifying component, and the fan outlet is connected to the first flow cavity.
[0005] The airflow ejected by the fan is decelerated in a spiral manner through the first flow cavity, and then the airflow is evenly diffused out of the rectification component through the wind holes, thereby replenishing the primary air and / or secondary air required for the combustion process of the burner, thereby improving the combustion efficiency of the burner.

[0047] Embodiment 1
[0048] See also Figures 1 to 4 Combined with Figure 5 As shown, an embodiment of the present application provides a flame distributor 1 for a burner 3 of a stove.
[0049] The fire distributor 1 provided in this embodiment includes a gas distributor seat 10 , a fire cover 11 , a first partition 12 and a second partition 13 .
[0050] The fire cover 11 is covered on the gas distributor seat 10, and the fire cover 11, the first partition 12 and the second partition 13 are connected as a whole to separate the mixing chamber 18, the first flow channel and the second flow channel inside the fire distributor 1. One of the first flow channel and the second flow channel is the gas flow channel 20, and the other is the air flow channel 19. The gas flow channel 20 is used to pass the mixed gas of the gas, and the air flow channel 19 is used to pass the supplementary air.
[0051] Among them, the overall structure formed by the fire cover 11, the first partition 12 and the second partition 13 can be taken in, placed in, and disassembled relative to the gas distributor 10. Optionally, the fire cover 11, the first partition 12 and the second partition 13 are integrally cast or integrally frame-formed, thereby being connected as a whole.
[0052] The second flow channel is separated from the first flow channel and the mixing chamber 18 by the second partition 13 . In other words, the second flow channel is located on one side of the second partition 13 , and the first flow channel and the mixing chamber 18 are located on the other side of the second partition 13 .
[0053] The first partition 12 is arranged on the side of the second partition 13 facing the first flow channel and the mixing chamber 18, and the first flow channel and the mixing chamber 18 are separated by the first partition 12, that is, the first flow channel and the mixing chamber 18 are respectively located on different sides of the first partition 12, and thus are separated by the first partition 12.
[0054] The first partition 12 is provided with a first air outlet 120 , and the first flow channel and the mixing chamber 18 are communicated with each other through the first air outlet 120 .
[0055] The second partition 13 is provided with a second air outlet 130 , and the second flow channel and the mixing chamber 18 are communicated with each other through the second air outlet 130 .
[0056] Specifically, when the first flow channel is the gas flow channel 20 and the second flow channel is the air flow channel 19, the gas flow channel 20 and the mixing chamber 18 are separated by the first partition 12 and communicated through the first gas outlet 120, so that the mixed gas in the gas flow channel 20 can flow into the mixing chamber 18 through the first gas outlet 120. The second partition 13 separates the air flow channel 19 from the gas flow channel 20 and the mixing chamber 18, and the air flow channel 19 and the mixing chamber 18 are communicated through the second gas outlet 130, so that the air in the air flow channel 19 can flow into the mixing chamber 18 through the second gas outlet 130.
[0057] When the first flow channel is the air flow channel 19 and the second flow channel is the gas flow channel 20, the air flow channel 19 and the mixing chamber 18 are separated by the first partition 12 and are connected through the first air outlet 120, so that the air in the air flow channel 19 can flow into the mixing chamber 18 through the first air outlet 120, and the second partition 13 separates the gas flow channel 20 relative to the air flow channel 19 and the mixing chamber 18, and the gas flow channel 20 and the mixing chamber 18 are connected through the second air outlet 130, so that the mixed gas in the gas flow channel 20 can flow into the mixing chamber 18 through the second air outlet 130.
[0058] Furthermore, as long as one of the first flow channel and the second flow channel is the gas flow channel 20 and the other is the air flow channel 19, the mixed gas from the gas flow channel 20 and the supplementary air from the gas flow channel 20 are mixed in the mixing chamber 18, so that the air ratio in the mixed gas can be increased, and the purpose of air supplementing the gas inside the igniter 1 can be achieved. Usually, the outer wall of the igniter 1 is provided with a fire hole connected to the mixing chamber 18, and the mixed gas after air supplement flows out through the fire hole and burns, so that the combustion efficiency of the igniter 1 can be improved by air supplement.
[0059] Therefore, the gas flow channel 20, the air flow channel 19 and the mixing chamber 18 of the ignition distributor 1 at least share the first partition 12 and the second partition 13, thereby reducing the material used in the ignition distributor 1 and lowering the cost.
[0060] In an optional solution of this embodiment, the fire cover 11, the first partition 12 and the second partition 13 are all ring-shaped. Specifically, the fire cover 11 and the second partition 13 are both sheet-shaped rings, and the second partition 13 is a cylindrical ring.
[0061] The second partition 13 is connected between the first partition 12 and the fire cover 11, and the first partition 12 and the fire cover 11 are connected at a certain axial interval through the second partition 13, so that the whole formed by the fire cover 11, the first partition 12 and the second partition 13 is cut along the axial direction of the gas separator seat 10, and the obtained cross-section is roughly C-shaped.
[0062] Optionally, the ring may be a flat ring or a butterfly-shaped ring.
[0063] The second flow channel is annular and is disposed at the second partition, and the second flow channel has an opening. Specifically, when the second flow channel is an air flow channel 19, as Figure 2 As shown in the figure, the fire cover 11 located at the top is an outer ring fire cover, the air flow channel 19 is annular and is arranged in the second partition 13, and the air flow channel 19 has an opening, wherein the air flow channel 19 is arranged in the second partition 13 and extends along the circumference of the second partition 13, so that the air flow channel 19 is an annular space with a certain volume. When the second flow channel is the gas flow channel 20, as shown in FIG. Figure 2 As shown in the figure, the fire cover 11 located at the bottom is an inner ring fire cover, the gas flow channel 20 is annular and is arranged in the second partition 13, and the gas flow channel 20 has an opening, wherein the gas flow channel 20 is arranged in the second partition 13 and extends along the circumference of the second partition 13.
[0064] The second flow channel has an opening, so that the air or gas mixture can enter the interior of the second flow channel through the opening of the second flow channel, and flow, diffuse and slow down along the annular second flow channel, thereby preventing the air or gas mixture in the second flow channel from impacting the flame at the fire hole.
[0065] The gas separator seat 10 includes a seat body and an annular side wall 14 arranged on the seat body. The first flow channel is annular and arranged on the seat body. The first flow channel has an opening, wherein the first flow channel is arranged on the seat body and extends along the circumference of the seat body, so that the first flow channel is an annular space with a certain volume, and the mixed gas or air can flow and diffuse in a ring shape in the first flow channel.
[0066] Optionally, the seat body is disc-shaped.
[0067] The fire cover 11 is overlapped on the annular side wall 14, that is, the top of the annular side wall 14 abuts against the bottom surface of the fire cover 11, and the fire cover 11 is supported by the annular side wall 14 so that the annular side wall 14, the first partition 12, the second partition 13 and the fire cover 11 enclose a mixing chamber 18, and the mixing chamber 18 is in a ring shape extending around the second partition 13.
[0068] The first partition 12 overlaps the seat body and covers the opening of the first flow channel, that is, the first partition 12 abuts against the seat body, the seat body supports the first partition 12, and the first partition 12 is arranged corresponding to the opening of the first flow channel, and closes the opening of the first flow channel, so that the first flow channel forms an independent annular space, that is, the first flow channel and the mixing chamber 18 share the first partition 12 as the wall surface.
[0069] The seat body contacts the second partition 13 and covers the opening of the second flow channel, that is, the second partition 13 abuts against the seat body, so that the second partition 13 is supported by the seat body, and the seat body closes the opening of the second flow channel, so that the second flow channel forms an independent annular space, that is, the mixing chamber 18 and the second flow channel share the second partition 13 as the wall surface.
[0070] Combination Figure 3 and Figure 4 As shown, for the outer ring fire cover, the second flow channel is the air flow channel 19, so that the first partition 12 overlaps the opening of the gas flow channel 20, and the seat body contacts the second partition 13 and seals the opening of the air flow channel 19; for the inner ring fire cover, the second flow channel is the gas flow channel 20, so that the first partition 12 overlaps the opening of the air flow channel 19, and the seat body contacts the second partition 13 and seals the opening of the gas flow channel 20.
[0071] It can be seen that the air flow channel 19, the mixing chamber 18 and the gas flow channel 20 of the ignition divider 1 will not form a closed annular cavity on the gas divider seat 10 and the fire cover 11, but will form an annular cavity with an opening, so that the structure of the gas divider seat 10 is simplified, especially the processing and manufacturing convenience is improved.
[0072] In addition, the first air outlet 120 is integrally formed with the first partition 12 or formed by a hole in the first partition 12. Similarly, the second air outlet 130 is integrally formed with the second partition 13 or formed by a hole in the second partition 13. Obviously, the molding process is simple and easy to manufacture.
[0073] In an optional scheme of this embodiment, a plurality of second air outlets 130 are provided, and the plurality of second air outlets 130 are arranged at intervals along the circumference of the second partition portion 13. Based on the fact that the second flow channel and the mixing chamber 18 are both annular in shape, the supplementary air or mixed gas in the second flow channel flows evenly and stably to various locations of the mixing chamber 18 through the plurality of second air outlets 130, thereby improving the supplementation and mixing effects of the supplementary air and the mixed gas in the mixing chamber 18.
[0074] In an optional scheme of this embodiment, a plurality of first air outlets 120 are provided, and the plurality of first air outlets 120 are arranged at intervals along the circumference of the first partition portion 12. Based on the fact that the first flow channel and the mixing chamber 18 are both annular in shape, the mixed gas or supplementary air in the first flow channel can flow to various locations around the mixing chamber 18 through the plurality of first air outlets 120, thereby improving the supplementation and mixing effect of the mixed gas and supplementary air in the mixing chamber 18.
[0075] In an optional solution of this embodiment, an air intake channel 170 is provided inside the seat body, one end of the air intake channel 170 passes through the outer peripheral side wall of the seat body, and the other end of the air intake channel 170 is connected to the air flow channel 19, so that the outside air can flow into the air flow channel 19 through the air intake channel 170.
[0076] Optionally, the seat body is provided with an air inlet connecting the air flow channel 19 and the air inlet passage 170 .
[0077] Optionally, the ignition distributor 1 further includes an air intake pipe 17 , the air intake pipe 17 penetrates the seat body, and an air intake passage 170 is formed inside the air intake pipe 17 .
[0078] Optionally, the ignition divider 1 also includes a fan 16, which is arranged at one end of the air intake passage away from the air flow passage 19, so that air is blown into the air flow passage 19 through the fan 16, and the air flows into the air flow passage 19 through the air intake passage, thereby improving the air intake efficiency of the supplementary air, that is, improving the air supply efficiency of the mixed gas.
[0079] In an optional scheme of the present embodiment, the cross-sectional area of the air flow channel 19 decreases in both the clockwise and counterclockwise directions along the circumference of the air flow channel 19 starting from the connection point with the air inlet channel. In other words, the cross-sectional area of the air flow channel 19 gradually decreases along the air flow direction, so that the cross-sectional area of the air flow channel 19 at various circumferential locations matches the flow rate of the supplementary air, so that the supplementary air swirls in the entire air flow channel 19, further improving the stability and distribution uniformity of the supplementary air flowing in the air flow channel 19 and toward the mixing chamber 18.
[0080] In an optional scheme of the present embodiment, the annular side wall 14 or the fire cover 11 is provided with a first fire hole 150, and the first fire hole 150 is a circular hole, that is, the fire holes of the ignition divider 1 include the first fire hole 150, and the first fire hole 150 connects the outside with the mixing chamber 18, so that the mixed gas after gas replenishment in the mixing chamber 18 flows out through the first fire hole 150 and burns at the first fire hole 150.
[0081] Specifically, the gas distributor seat 10 includes two annular side walls 14, and the two annular side walls 14 are respectively arranged at the middle and the edge of the seat body, and the gas distributor seat 10 is provided with a gas flow channel 20 corresponding to the two annular side walls 14. The two annular side walls 14 are overlapped with fire covers 11, which are an inner ring fire cover and an outer ring fire cover respectively, and the inner ring fire cover and the outer ring fire cover are both connected with a first partition 12 and a second partition 13. Thus, a gas flow channel 20, an air flow channel 19 and a mixing chamber 18 are arranged in the middle of the ignition divider 1, and a gas flow channel 20, an air flow channel 19 and a mixing chamber 18 are arranged at the edge of the ignition divider 1. Among them, as Figure 4 and Figure 5 As shown, the inner ring fire cover is provided with a first fire hole 150 , and the annular side wall 14 corresponding to the outer ring fire cover is provided with a first fire hole 150 .
[0082] Optionally, there are multiple first fire holes 150 , and the multiple first fire holes 150 are evenly spaced and arranged along the circumference of the gas distributor 10 .
[0083] In an optional solution of this embodiment, a second fire hole 151 is provided at the abutment between the annular side wall 14 and the fire cover 11, and the second fire hole 151 is a strip groove, that is, the fire hole of the fire distributor 1 includes the second fire hole 151, wherein the abutment between the annular side wall 14 and the fire cover 11 is the top edge of the annular side wall 14, and the second fire hole 151 is a strip groove provided at the top edge of the annular side wall 14. Figure 1 and Figure 3 As shown, a second fire hole 151 is provided at the top edge of the outer ring fire cover.
[0084] The second fire hole 151 does not need additional drilling processing and can be configured to be integrally formed with the annular side wall 14, which can simplify the processing technology and reduce the manufacturing cost of the ignition divider 1 and the burner 3 using the ignition divider 1.
[0085] Optionally, the cross-sectional shape of the second fire hole 151 may be square, elongated or trapezoidal, so that the shape is regular and easy to shape. The cross-sectional shape of the second fire hole 151 may be selected according to actual needs.
[0086] In an optional solution of this embodiment, the fire cover 11 is provided with a fire outlet groove 110 , and at least part of the fire outlet groove 110 extends to the side of the annular side wall 14 facing the second partition 13 so that the fire outlet groove 110 is connected to the mixing chamber 18 .
[0087] In this technical solution, the mixed gas in the mixing chamber 18 can not only flow out to the outside of the ignition divider 1 through the second fire hole 151 and the first fire hole 150 for combustion, but can also flow out of the ignition divider 1 through the fire outlet groove 110 and burn. Since the fire cover 11 is buckled on the top of the gas distributor seat 10, the fire outlet groove 110 on the fire cover 11 can increase the distribution area of the flame in the space above the ignition divider 1 and the burner 3, enhance the transferability of the flame between the fire holes, and strengthen the heat exchange between the flame and the bottom of the pot, thereby improving the thermal efficiency.
[0088] Optionally, a plurality of fire outlet grooves 110 are provided, and the plurality of fire outlet grooves 110 are arranged at intervals along the circumference of the ignition distributor 1 .
