Description
Technical Field
[0001] The utility model relates to the technical field of kitchen utensils, in particular to a fire distributor and a burner. Background Art
[0002] The burner is an essential component of a gas stove. The fire cover of the burner is set on the fire distributor. Some fire distributors are equipped with a guide device to guide the incoming gas. Most of the guide devices are connected to the outer ring wall of the burner. There is no gap between the guide device and the outer ring wall, which leads to very little gas at the connection between the guide device and the outer ring wall on one side of the gas outlet direction. The gas diffusion in the burner is uneven, the flame is uneven, and it is easy to cause flying fire or flame separation. Utility Model Content
[0003] In order to at least partially solve the problems existing in the prior art, the utility model provides a fire distributor, and the technical solution is as follows.
[0004] The fire divider includes an inner wall, an outer wall and a bottom wall, which together form a fire divider cavity, and an air inlet connecting the fire divider cavity with the outside is arranged on the bottom wall; a guide plate is arranged on the upper part of the air inlet in the fire divider cavity, and the guide plate has a first side edge close to the outer wall and a second side edge close to the inner wall, a first gap exists between the first side edge and the outer wall, and a second gap exists between the second side edge and the inner wall.
[0005] The utility model provides a fire divider, wherein a first gap exists between the guide plate and the outer side wall, and a second gap exists between the second side and the inner side wall. The airflow diffuses in the direction of the outer side wall and the inner side wall through the first gap and the second gap, thereby increasing the residence time of the airflow in the fire divider cavity, thereby increasing the gas mixing time, making the gas mixing more uniform, and avoiding flying fire or flame separation.
[0006] Exemplarily, the guide plate has a first surface and a second surface, the first surface is opposite to the second surface, and the first surface is farther from the bottom wall than the second surface, and a guide hole is provided on the guide plate, which runs from the first surface to the second surface. In this way, the guide hole guides the local airflow, so that part of the airflow diffuses from the guide hole to the top of the first surface, reduces the airflow pressure of the local outer wall, avoids flying fire or flame separation, and quickly fills the airflow above the first surface in the fire separation cavity, increases the gas mixing time, makes the gas mixing more uniform, and makes the flame more uniform.
[0007] Exemplarily, the first interval is smaller than the second interval. In this way, the airflow diffused to the outer wall is less than the airflow diffused to the inner wall, because the fire outlet is closer to the outer wall than the inner wall, avoiding excessive airflow diffused from the first interval to cause flying fire or flame separation.
[0008] Exemplarily, the distance between the first side and the bottom wall is smaller than the distance between the second side and the bottom wall. In this way, the first side is closer to the bottom wall than the second side, so that the guide plate and the bottom wall form a certain angle, control the airflow direction, reduce the airflow pressure on the outer wall, avoid flying fire or flame separation, and increase the residence time of the airflow in the fire separation chamber, increase the gas mixing time, and make the gas mixing more uniform.
[0009] Exemplarily, an inclination angle α is formed between the guide plate and the bottom wall, and α is 10° to 30°. For example, α is 10°, 20° or 30°, etc. In this way, the guide plate controls the airflow direction, reduces the airflow pressure on the outer wall, increases the residence time of the airflow in the fire distribution chamber, increases the gas mixing time, and makes the gas mixing more uniform.
[0010] Exemplarily, the guide plate is connected to the bottom wall via a connecting piece. In this way, the guide plate is fixedly arranged in the fire distribution chamber.
[0011] Exemplarily, the end of the connecting member near the bottom wall is bent and extended to form a connecting plate, and the connecting plate is connected to the bottom wall. In this way, the connecting plate increases the connection area between the connecting member and the bottom wall, making the connection between the connecting member and the bottom wall more stable.
[0012] Exemplarily, the guide plate has a first end and a second end opposite to each other in the circumferential direction, the connecting member includes a first connecting portion and a second connecting portion, the first end is connected to the bottom wall via the first connecting portion, and the second end is connected to the bottom wall via the second connecting portion. In this way, both opposite ends of the guide plate are connected to the bottom wall, so that the position of the guide plate is more stable.
[0013] Exemplarily, the orthographic projection of the guide plate toward the plane where the bottom wall is located completely covers the air inlet. In this way, the guide plate guides all the gas entering the air inlet, reduces the air flow pressure of the local outer wall, avoids flying fire or flame separation, and makes the gas in the fire separation chamber more evenly mixed, making the flame more uniform.
[0014] Exemplarily, the air inlet is connected to an air inlet assembly, and a connecting groove is provided at the end of the air inlet assembly near the air inlet, and the edge of the air inlet is bent and extended toward the center of the air inlet to form a connecting edge, and the connecting edge is embedded in the connecting groove. In this way, the air inlet assembly is firmly connected to the air inlet to prevent gas leakage.
[0015] According to another aspect of the utility model, a burner is provided, comprising a fire cover and the above-mentioned flame divider, wherein the fire cover is arranged on the flame divider. The burner provided by the utility model, because it comprises the above-mentioned flame divider, must have the technical effect of the above-mentioned flame divider.
[0016] Exemplarily, the fire cover includes an inner connecting wall and an outer connecting wall, the inner connecting wall is connected to the inner side wall, the outer connecting wall is connected to the outer side wall, a third gap exists between the second side edge and the inner connecting wall, and the outer connecting wall has a fire outlet hole connecting the fire separation cavity with the outside. In this way, part of the airflow diffuses from the third gap, and the airflow diffuses in multiple directions in the fire separation cavity, so that the gas mixing is more uniform.

DETAILED DESCRIPTION
[0028] In the following description, a large number of details are provided so that the present invention can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only illustrates preferred embodiments of the present invention, and the present invention can be implemented without one or more of such details. In addition, in order to avoid confusion with the present invention, some technical features known in the art are not described in detail.
[0029] According to one aspect of the utility model, a flame distributor is provided, which is mainly applied to a burner. Therefore, according to another aspect of the utility model, a burner is provided.
[0030] Firstly, the fire distributor will be described in detail below in conjunction with the accompanying drawings.
[0031] See also Figures 1 to 4 The fire divider 100 includes an inner wall 110, an outer wall 120 and a bottom wall 130, which enclose a fire dividing chamber 101. The bottom wall 130 is provided with an air inlet 131 connecting the fire dividing chamber 101 with the outside; a guide plate 140 is provided on the upper part of the air inlet 131 in the fire dividing chamber 101, and the guide plate 140 has a first side 141 close to the outer wall 120 and a second side 142 close to the inner wall 110, a first gap 1411 is present between the first side 141 and the outer wall 120, and a second gap 1421 is present between the second side 142 and the inner wall 110.
[0032] In the fire divider 100 provided by the utility model, there is a first gap 1411 between the guide plate 140 and the outer wall 120, and a second gap 1421 between the second side 142 and the inner wall 110. The airflow is diffused in the direction of the outer wall 120 and the inner wall 110 through the first gap 1411 and the second gap 1421, which increases the residence time of the airflow in the fire divider chamber 101, thereby increasing the mixing time, making the gas mixing more uniform, and avoiding flying fire or flame separation.
[0033] In one embodiment of the utility model, the first side 141 and the second side 142 are arcs cocentric with the bottom wall 130, so that the distance between the first side 141 and the outer wall 120 is the same at all locations, so that the airflow is evenly diffused at the first interval 1411, and the distance between the second side 142 and the inner wall 110 is the same at all locations, so that the airflow is evenly diffused at the second interval 1421, and the guide plate 140 formed by the first side 141 and the second side 142 is fan-shaped.
[0034] In one embodiment of the present invention, a base 170 is connected to the side of the bottom wall 130 away from the fire divider chamber 101 . The base 170 can be connected to the bottom wall 130 by welding or fasteners, and is used to support the fire divider 100 .
[0035] Combined with reference Figure 1 , Figure 3 , Figure 4 and Figure 6 The guide plate 140 has a first surface 143 and a second surface 144. The first surface 143 is opposite to the second surface 144, and the first surface 143 is farther away from the bottom wall 130 than the second surface 144. The guide plate 140 is provided with a guide hole 145 that penetrates from the first surface 143 to the second surface 144. The guide hole 145 guides the local airflow, so that part of the airflow is diffused from the guide hole 145 to the top of the first surface 143, reducing the airflow pressure of the local outer wall 120, avoiding flying fire or flame separation, and quickly filling the airflow above the first surface 143 in the fire-dividing cavity 101, increasing the gas mixing time, making the gas mixing more uniform, and making the flame more uniform.
[0036] In an embodiment of the present invention, the guide holes 145 are evenly spaced throughout the guide plate 140 , so that the airflow is evenly diffused after passing through the guide holes 145 .
[0037] See also Figure 4 , the distance between the first side 141 and the outer wall 120 (i.e., the first interval 1411) is smaller than the distance between the second side 142 and the inner wall 110 (i.e., the second interval 1421). The airflow diffused to the outer wall 120 is less than the airflow diffused to the inner wall 110, because the fire outlet is closer to the outer wall 120 than the inner wall 110, thereby avoiding excessive airflow diffused from the first interval 1411 to cause flying fire or flame separation.
[0038] Combined with reference Figure 3 , Figure 4 and Figure 6, the distance between the first side 141 and the bottom wall 130 is smaller than the distance between the second side 142 and the bottom wall 130. The first side 141 is closer to the bottom wall 130 than the second side 142, so that the guide plate 140 and the bottom wall 130 form a certain angle, control the airflow direction, reduce the airflow pressure on the outer wall 120, avoid flying fire or flame separation, and increase the residence time of the airflow in the fire separation chamber 101, increase the gas mixing time, and make the gas mixing more uniform.
[0039] Combined with reference Figure 3 , Figure 4 and Figure 6 The guide plate 140 and the bottom wall 130 form an inclination angle α, and α is 10° to 30°. For example, α is 10°, 20° or 30°, etc. The guide plate 140 controls the airflow direction, reduces the airflow pressure on the outer wall 120, increases the residence time of the airflow in the fire-dividing chamber 101, increases the gas mixing time, and makes the gas mixing more uniform. The design of the inclination angle α makes the gas volume above and below the guide plate 140 in the fire-dividing chamber 101 similar, so that the gas is evenly dispersed.
[0040] Combined with reference Figure 1 , Figure 3 and Figure 4 The guide plate 140 is connected to the bottom wall 130 via a connecting piece 150. The guide plate 140 is fixedly arranged in the fire distribution chamber 101.
[0041] In one embodiment of the present invention, the guide plate 140 and the connecting member 150 can be manufactured in one piece, or the guide plate 140 and the connecting member 150 can be connected by welding or fasteners.
[0042] In one embodiment of the utility model, the guide plate 140 can be connected to the outer wall 120 and / or the inner wall 110 (not shown in the figure) through a connecting piece 150. Compared with the guide plate 140 being connected to the outer wall 120 and / or the inner wall 110, when the guide plate 140 is connected to the bottom wall 130, there is no connecting piece 150 blocking the first interval 1411 and the second interval 1421, so that the airflow can be evenly diffused at the first interval 1411 and the second interval 1421.
[0043] See also Figure 1 The end of the connecting member 150 close to the bottom wall 130 is bent and extended to form a connecting plate 1501, and the connecting plate 1501 is connected to the bottom wall 130. The connecting plate 1501 increases the connection area between the connecting member 150 and the bottom wall 130, making the connection between the connecting member 150 and the bottom wall 130 more stable.
[0044] In an embodiment of the present invention, the connecting plate 1501 can be connected to the bottom wall 130 by welding or fastener connection.
[0045] Combined with reference Figure 1 and Figure 4 The guide plate 140 has a first end 146 and a second end 147 opposite to each other in the circumferential direction, and the connecting member 150 includes a first connecting portion 151 and a second connecting portion 152. The first end 146 is connected to the bottom wall 130 through the first connecting portion 151, and the second end 147 is connected to the bottom wall 130 through the second connecting portion 152. Both opposite ends of the guide plate 140 are connected to the bottom wall 130, so that the position of the guide plate 140 is more stable.
[0046] In one embodiment of the utility model, the connecting member 150 may also include multiple connecting parts (not shown in the figure), and the first connecting part 151, the second connecting part 152 or multiple connecting parts can be connected at any position of the second surface 144 of the guide plate 140, so that the guide plate 140 can be stably connected to the bottom wall 130.
[0047] Combined with reference Figure 1 , Figure 3 and Figure 4 The orthographic projection of the guide plate 140 toward the plane where the bottom wall 130 is located completely covers the air inlet 131. The guide plate 140 guides all the gas entering the air inlet 131, reduces the air flow pressure of the local outer wall 120, avoids flying fire or flame separation, and makes the gas in the fire chamber 101 more evenly mixed, making the flame more uniform.
[0048] Combined with reference Figure 2 , Figure 3 , Figure 5 and Figure 6 The air inlet 131 is connected to an air inlet assembly 160, and a connecting groove 161 is provided at the end of the air inlet assembly 160 near the air inlet 131. The edge of the air inlet 131 is bent and extended toward the center of the air inlet 131 to form a connecting edge 1311, and the connecting edge 1311 is embedded in the connecting groove 161. The air inlet assembly 160 is firmly connected to the air inlet 131 to prevent gas leakage.
[0049] According to another aspect of the present invention, a burner is provided. Figure 5 and Figure 6 , including a fire cover 200 and the above-mentioned fire distributor 100, the fire cover 200 is covered on the fire distributor 100. Since the burner provided by the utility model includes the above-mentioned fire distributor 100, the burner must have the technical effect of the above-mentioned fire distributor 100.
[0050] See also Figure 5 and Figure 6The fire cover 200 includes an inner connecting wall 210 and an outer connecting wall 220. The inner connecting wall 210 is connected to the inner side wall 110, and the outer connecting wall 220 is connected to the outer side wall 120. There is a third interval between the second side edge 142 and the inner connecting wall 210. The outer connecting wall 220 has a fire outlet 230 connecting the fire chamber 101 with the outside. Part of the airflow diffuses from the third interval, and the airflow diffuses in multiple directions in the fire chamber 101, so that the gas mixes more evenly. The fire cover 200 is placed on the fire distributor 100, so that the fire chamber 101 becomes a closed space, and the gas flows out of the burner from the fire outlet 230.
[0051] In one embodiment of the present invention, the flame outlet holes 230 are evenly spaced on the outer connecting wall 220 to ensure good flame uniformity.
