Description

Technical Field

[0001] The present application relates to the technical field of cooking equipment, and in particular to a flame distributor and a burner. Background Art

[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.

[0006] It can be seen that in this scheme, the secondary air supplied by the fan has a fast flow rate. Although it is decelerated by the flow cavity, there is still a significant flow rate difference compared to the natural air supply in the space around the fire hole.

[0044] Embodiment 1

[0045] See also Figures 1 to 3 Combined with Figure 4 As shown, an embodiment of the present application provides a flame distributor 1 for a burner 2 of a stove.

[0046] The ignition distributor 1 provided in this embodiment is internally provided with a first flow channel, a second flow channel and a mixing chamber 102, wherein one of the first flow channel and the second flow channel is a gas flow channel 100, and the other is an air flow channel 101, the gas flow channel 100 is used to pass the mixed gas of the gas, and the air flow channel 101 is used to pass the air.

[0047] The second flow channel is separated from the first flow channel and the mixing chamber 102 by the first partition 12. In other words, the first partition 12 has a first side and a second side opposite to each other. The first flow channel and the mixing chamber 102 are arranged on the first side of the first partition 12, and the second flow channel is arranged on the second side of the first partition 12, so that the first partition 12 separates the second flow channel relative to the first flow channel and the mixing chamber 102.

[0048] The second flow channel and the mixing chamber 102 are separated by the second partition 13. In other words, the second partition 13 has a first side and a second side opposite to each other. The second flow channel is arranged on the first side of the second partition 13, and the mixing chamber 102 is arranged on the second side of the second partition 13, so that the second partition 13 separates the second flow channel and the mixing chamber 102.

[0049] The first partition 12 is provided with a first air outlet 105 , and the first flow channel and the mixing chamber 102 are communicated through the first air outlet 105 , so that the mixed gas or air in the first flow channel can flow into the mixing chamber 102 through the first air outlet 105 .

[0050] The second partition 13 is provided with a second air outlet 106 , and the second flow channel and the mixing chamber 102 are communicated through the second air outlet 106 , so that the air or mixed gas in the second flow channel can flow into the mixing chamber 102 through the second air outlet 106 .

[0051] Therefore, the air supplied by the air flow channel 101 to the mixing chamber 102 and the gas supplied by the gas flow channel 100 to the mixing chamber 102 are mixed in the mixing chamber 102, so that the mixed gas can be supplemented with air inside the ignition distributor 1, thereby improving the combustion efficiency of the mixed gas.

[0052] It can be seen that the ignition distributor 1, by providing the air flow channel 101, the gas flow channel 100 and the mixing chamber 102, realizes the air replenishment of the mixed gas inside the ignition distributor 1, and provides a new air replenishment method in addition to the natural air injection of the ejector pipe 211 of the burner head and the air injection in the space around the fire hole. In addition, the air flow channel 101, the gas flow channel 100 and the mixing chamber 102 share the first partition 12 and the second partition 13, which realizes the simplification of the structure, effectively reduces the material used in the gas distributor 10 and the ignition distributor 1, and is conducive to cost saving.

[0053] In an optional solution of this embodiment, the fire distributor 1 includes a gas distributor seat 10 and a fire cover 11 .

[0054] The gas distributor seat 10 includes a first annular side wall 16 and a second annular side wall 17 which are arranged around the axis of the gas distributor seat 10 , and a spacing space is formed between the first annular side wall 16 and the second annular side wall 17 .

[0055] The second partition 13 is annular and is disposed between the first annular side wall 16 and the second annular side wall 17 . In other words, a spacing space is formed between the second partition 13 and the first annular side wall 16 , and a spacing space is formed between the second partition 13 and the second annular side wall 17 .

[0056] The top of the second partition 13 is spaced apart from the top of the first annular side wall 16 , that is, the top of the first partition 12 is not directly connected to the top of the first annular side wall 16 , so that the spacing space between the second partition 13 and the first annular side wall 16 is open.

[0057] The first partition 12 is connected between the first annular side wall 16 and the second partition 13. The first partition 12 divides the interval space between the first annular side wall 16 and the second partition 13 into a mixing chamber 102 and a first flow channel. The mixing chamber 102 is higher than the first flow channel. Therefore, when the ignition divider 1 is in use, the mixing chamber 102 is located above the first partition 12, the first flow channel is located below the first partition 12, and the mixing chamber 102 is open.

[0058] The second partition 13 and the second annular side wall 17 enclose a second flow channel. In other words, the interval space between the second partition 13 and the second annular side wall 17 is the second flow channel.

[0059] A fire cover 11 is buckled on the top of the first annular side wall 16 and the second annular side wall 17, so that the fire cover 11 covers the open portion of the mixing chamber 102 and closes the mixing chamber 102. Furthermore, the first annular side wall 16 is provided with a fire hole, which is connected to the mixing chamber 102, and the mixed gas of the fuel gas flows out from the mixing chamber 102 through the fire hole and burns.

[0060] In this embodiment, the fire hole includes a first fire hole 103, which is a strip groove arranged at the junction of the first annular side wall 16 and the fire cover 11. In other words, the junction of the first annular side wall 16 and the fire cover 11 is the top edge of the first annular side wall 16, and the first fire hole 103 is a strip groove arranged at the top edge of the first annular side wall 16.

[0061] The first fire hole 103 does not need additional drilling processing and can be configured to be integrally formed with the first annular side wall 16, which can simplify the processing technology and reduce the manufacturing cost of the ignition divider 1 and the burner 2 using the ignition divider 1.

[0062] Optionally, the cross-sectional shape of the first fire hole 103 may be square, elongated or trapezoidal, so that the shape is regular and easy to shape. The cross-sectional shape of the first fire hole 103 may be selected according to actual needs.

[0063] In this embodiment, see Figure 3 The dotted line in the figure shows the axis of the fire divider. The extension direction of the axis of the fire divider is the axial direction of the fire divider. The first fire hole 103 has a depth along the axial direction of the fire divider 1. The depth of the first fire hole 103 is 0.5-4mm, for example 0.5mm, 1mm, 2mm, 3mm or 4mm.

[0064] The first fire hole 103 has a width along the circumference of the fire distributor 1 , and the width of the first fire hole 103 is 1.5-5 mm, for example, 1.5 mm, 2 mm, 3 mm, 4 mm or 5 mm.

[0065] The first fire hole 103 has a length along the radial direction of the fire distributor 1 , and the length of the first fire hole 103 is 2-8 mm, for example, 2 mm, 4 mm, 6 mm or 8 mm.

[0066] Thus, by limiting the depth, width and length of the first fire hole 103 respectively, the size of each dimension of the first fire hole 103 will not be too large, ensuring that the mixed gas provided by the gas flow channel 100 and the air provided by the air flow channel 101 can be fully mixed in the mixing chamber 102, and the air replenishment effect is not weakened. In addition, the size of each dimension of the first fire hole 103 will not be too small, ensuring that the mixed gas can flow out smoothly through the first fire hole 103 and burn.

[0067] Optionally, the cross-sectional shape of the first fire hole 103 is square, rectangular or trapezoidal.

[0068] In an optional scheme of this embodiment, the fire hole includes a second fire hole 104, and the second fire hole 104 is a circular hole lower than the first fire hole 103. In other words, the second fire hole 104 is a circular hole, and the second fire hole 104 is lower than the first fire hole 103, thereby making full use of the first annular side wall 16 to set the second fire hole 104, and the mixed gas in the mixing chamber 102 is discharged and burned together through the first fire hole 103 and the second fire hole 104, thereby improving the combustion efficiency.

[0069] In this embodiment, a plurality of the first fire holes 103 and a plurality of the second fire holes 104 are provided, and the plurality of the first fire holes 103 and the plurality of the second fire holes 104 are arranged at intervals along the circumferential direction of the first annular side wall 16 .

[0070] Along the circumference of the flame divider 1, each second fire hole 104 is located between two adjacent first fire holes 103, thereby preventing the first fire holes 103 and the second fire holes 104 from competing for the mixed gas and air in the mixing chamber 102, and shortening the distance between adjacent fire holes, thereby improving the flame transferability between the fire holes, making the flame combustion more stable and more efficient.

[0071] 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 first annular side wall 16 facing the mixing chamber 102 , so that the fire outlet groove 110 is connected to the mixing chamber 102 .

[0072] Therefore, the mixed gas in the mixing chamber 102 can not only flow out to the outside of the ignition divider 1 through the fire hole for combustion, but 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 ignition divider 1, 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 2, 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.

[0073] Optionally, the fire cover 11 is a sheet-shaped ring. Optionally, the ring can be a flat ring or a butterfly ring.

[0074] 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 .

[0075] In a specific example, the fire divider 1 includes an inner ring portion and an outer ring portion sleeved outside the inner ring portion, and both the inner ring portion and the outer ring portion include a first annular side wall 16, a second annular side wall 17, a first partition 12, a second partition 13 and a fire cover 11. Among them, the first annular side wall 16 of the inner ring portion (see Figure 3 The structure shown by the first reference numeral 16 from the right in the figure) is located on the second annular side wall 17 (see Figure 3 The inner side of the structure shown by the first number 17 from the right side in the figure) is formed so that the inner ring portion is ignited through the inner side thereof, and the first flow channel of the inner ring portion is the air flow channel 101 (see Figure 3 The second flow channel of the inner ring is the gas flow channel 100 (see Figure 3 The structure shown by the first reference numeral 100 from the right in the figure); the first annular side wall 16 of the outer ring portion (see Figure 3 The structure shown by the first reference numeral 16 from the left in the figure) is located on the second annular side wall 17 (see Figure 3 The outer side of the structure shown by the first number 17 from the left in the figure) is formed so that the outer ring portion emits fire through its outer side, and the first flow channel of the outer ring portion is the gas flow channel 100 (see Figure 3 The second flow channel of the outer ring portion is an air flow channel 101 (see Figure 3 The structure shown by the first reference numeral 101 from the left).

[0080] Further optionally, the burner 2 also includes an air inlet pipe 15 connected to the air distributor seat 10 of the ignition distributor 1, one end of the air inlet pipe 15 is connected to the fan 20, and the other end of the connecting pipe is connected to the air flow channel 101.

[0081] In addition, since the air flow channel 101 is annular, the air blown into the air flow channel 101 by the fan 20 swirls inside it and is buffered and decelerated, and then flows into the mixing chamber 102 to mix with the mixed gas, flows out through the first fire hole 103, the second fire hole 104 and the fire outlet groove 110 and burns, thereby ensuring a high air replenishment efficiency while avoiding air flow impact on the flame caused by excessive wind speed, thereby improving the combustion efficiency.

The nozzle 212 is used to inject gas into the ejector tube 211, and under the action of the gas jet, the outside air is ejected into the ejector tube 211 through the air ejection channel, so that the gas and air are introduced into the mixing chamber through the ejector tube 211, and the air is supplemented in the form of a jet, and the gas replenishment efficiency is too high compared to the natural gas replenishment method.

[0085] Furthermore, the mixed gas obtained after the air and the fuel gas are mixed in the gas mixing chamber serves as the gas source of the fuel gas flow passage 100 and flows into the ignition source 1 of the gas distributor seat 10 .

[0086] Furthermore, the burner 2 performs a primary air supplement to the fuel gas through the air injection channel of the injection tube 211, and performs a secondary air supplement to the fuel gas through the air flow channel 101. Optionally, a groove-shaped air flow port 14 can be provided at the top of the gas distributor 10 near the fire hole and the fire outlet groove 110 to perform a tertiary air supplement to the fuel gas.
