[0036] The utility model provides a burner 100 for a gas stove.

[0037] See also Figures 1 to 7 In one embodiment of the present utility model, the burner 100 comprises:

[0038] Outer ring fire cover 1; and

[0039] An annular gas distribution plate 2 is provided with a first air inlet channel 21 on its inner periphery and an outer ring channel 22 on its outer periphery. The outer ring fire cover 1 is installed on the outer ring channel 22. The annular gas distribution plate 2 is also provided with a gas channel 23 and an air inlet channel 24 which are separated from each other. The gas channel 23 and the air inlet channel 24 are alternately arranged along the circumference of the annular gas distribution plate 2. One end of the gas channel 23 is connected to the first air inlet channel 21, and the other end is connected to the outer ring channel 22. A flow baffle is provided on one end of the gas channel 23 facing the outer ring channel 22, and the air inlet channel 24 axially penetrates the annular gas distribution plate 2.

[0040] Specifically, the annular gas distribution plate 2 is arranged in an annular shape as a whole, so the annular gas distribution plate 2 has an inner periphery and an outer periphery, the inner periphery forms a first air inlet channel 21, and the outer periphery forms an outer ring channel 22, that is, the outer ring channel 22 is arranged on the outer periphery of the first air inlet channel 21, and the gas channel 23 is arranged between the first air inlet channel 21 and the outer ring channel 22. One end of the gas channel 23 is connected to the first air inlet channel 21, and the other end is connected to the outer ring channel 22, so that part of the gas enters the gas channel 23 from the first air inlet channel 21 and then enters the outer ring channel 22, and passes out from the first outlet hole 11 of the outer ring fire cover.

[0041] However, since the gas channel 23 and the air inlet channel 24 are arranged alternately along the circumference of the annular gas distribution plate 2, the gas channel 23 does not completely cover the outer circumference of the annular gas distribution plate 2. Figure 1 and Figure 4In this embodiment, the gas channel 23 and the air inlet channel 24 are both configured in three numbers, and the gas channel 23 is configured as a straight channel extending radially along the annular gas distribution plate 2, and the outer ring channel 22 includes a first section facing the gas channel 23 and a second section facing the air inlet channel 24, and the first section and the second section are arranged alternately in sequence. The outer ring channel 22 is directly connected to the first section of the gas channel 23, and is connected to the second section through the first section. Therefore, when the gas enters the outer ring channel from the gas channel 23, the gas first enters the first section and then enters the second section. This will inevitably lead to the gas concentration in the first section of the outer ring channel 22 being higher than the concentration of the gas in the second section, which in turn leads to uneven gas outlet of the first air outlet 11 on the outer ring fire cover 1, resulting in uneven flame intensity and distribution at the outer ring fire cover 1.

[0042] Therefore, a baffle is provided at one end of the gas channel 23 facing the outer ring channel 22, that is, a baffle plate 27 is provided at one end of the gas channel 23 connected to the first section, thereby providing a certain buffering effect for the gas from the gas channel 23 to the first section, and the baffle has a certain guiding effect, so that the gas flows along the extension direction of the baffle plate 27, thereby further guiding the gas to the second section, thereby promoting the uniformity of the concentration of the gas in the outer ring channel 22, reducing the flame intensity and the possibility of uneven distribution at the outer ring fire cover 1, thereby improving the combustion performance of the gas stove, improving the cooking effect and the cooking quality of food.

[0043] The air inlet channel 24 penetrates the annular air distributor 2 along the axial direction of the annular air distributor 2, thereby providing air to the inner ring fire cover 3 and the outer ring fire cover 1, thereby promoting full mixing of the gas and air, and the gas channel 23 and the air inlet channel 24 are alternately arranged along the circumference of the annular air distributor 2, thereby promoting the uniformity of mixing of the gas and air in the outer ring fire cover 1, ensuring full contact between the gas and the external air at the outer ring fire cover 1, thereby reducing the possibility of incomplete combustion of the burner 100.

[0044] In the embodiments of the present invention, please refer to Figures 1 to 7 The annular gas distribution plate 2 includes an upper cover assembly 26 and a lower cover assembly 25, the upper cover assembly 26 and the lower cover assembly 25 are mutually enclosed to form a gas channel 23 and an outer ring channel 22, the inner periphery of the outer ring fire cover 1 is connected to the outer edge of the upper cover assembly 26, the outer periphery of the outer ring fire cover 1 is connected to the outer edge of the lower cover assembly 25, and the air inlet channel 24 runs through the upper cover assembly 26 and the lower cover assembly 25;

[0045] The baffle is installed on the upper cover assembly 26 and / or the lower cover assembly 25 , and is provided with a flow hole 271 connected to the first air outlet 11 of the outer ring fire cover 1 .

[0046] Specifically, the annular gas distributor 2 includes an upper cover assembly 26 and a lower cover assembly 25, which are mutually enclosed to form a gas channel 23 and an outer ring channel 22, that is, the upper cover assembly 26 and the lower cover assembly 25 are mutually spliced ​​and fixed, so that the upper cover assembly 26 and the lower cover assembly 25 can be independently manufactured and processed, and then assembled together, so as to facilitate the processing of the burner 100. The upper cover assembly 26 and the lower cover assembly 25 are covered to form the gas channel 23. This design allows the annular gas distributor 2 to be easily replaced or maintained without disassembling the entire burner 100.

[0047] The inner periphery of the outer ring fire cover 1 is connected to the outer edge of the upper cover assembly 26, and the outer periphery of the outer ring fire cover 1 is connected to the outer edge of the lower cover assembly 25, so that the outer ring fire cover 1 is fixed to the annular gas distribution plate 2. The outer ring fire cover 1 can be detachably connected to the annular gas distribution plate 2, so as to facilitate the replacement of the outer ring fire cover 1 and the maintenance of the burner 100, and can also be non-detachably connected to the annular gas distribution plate 2, so as to ensure the sealing of the outer ring fire cover 1 and the annular gas distribution plate 2.

[0048] The baffle 27 can be installed on either the upper cover assembly 26 or the lower cover assembly 25, or one side of the baffle 27 is connected to the upper cover assembly 26 and the other side is connected to the lower cover assembly 25, that is, in this solution, the installation position of the baffle 27 is not limited, and can be specifically set according to the structure of the annular gas distribution plate 2. The baffle is provided with a flow hole 271 connected to the first gas outlet 11 of the outer ring fire cover 1, so that the gas from the gas channel 23 to the first section is divided into two parts, one part enters the first section through the flow hole 271, and the other part flows to the second section along the extension direction of the baffle 27, so that the baffle 27 can provide a buffer for the flow of the gas, but does not completely block the gas from flowing to the first section, thereby further promoting the uniformity of the concentration of the gas in the outer ring channel 22.

[0049] In order to facilitate the processing of the annular gas distribution plate 2, in the embodiment of the present utility model, please refer to Figures 1 to 3The inner circumference of the outer ring fire cover 1 is provided with a first flange 12 extending downward, and the upper cover assembly 26 has a second flange 261 extending upward, the first flange 12 is connected to the second flange 261, and the first flange 12 abuts against the side of the second flange 261 away from the lower cover assembly 25, that is, the outer ring fire cover 1 and the upper cover assembly 26 are formed separately, and in order to reduce the occurrence of gas leakage between the outer ring fire cover 1 and the upper cover assembly 26, the inner circumference of the outer ring fire cover 1 is provided with a first flange 12 extending downward, and the upper cover assembly 26 has a second flange 261 extending upward, and the first flange 12 and the second flange 261 abut against each other and are connected together, thereby increasing the contact area between the outer ring fire cover 1 and the upper cover assembly 26, thereby ensuring both the connection strength between the outer ring fire cover 1 and the upper cover assembly 26 and the sealing between the outer ring fire cover 1 and the upper cover assembly 26. The first flange 12 abuts against the side of the second flange 261 away from the lower cover assembly 25, that is, the first flange 12 is arranged on the inner side of the second flange 261 section, that is, the outer ring fire cover 1 is covered on the outer edge of the upper cover assembly 26, thereby further improving the sealing performance of the outer ring fire cover 1 and the upper cover assembly 26.

[0050] In another embodiment of the present invention, please refer to Figures 4 to 7 The outer ring fire cover 1 and the upper cover assembly 26 are integrally formed, that is, the outer ring fire cover 1 and the annular upper cover 265 are integrally formed, thereby reducing the assembly process of the outer ring fire cover 1 and the annular gas distribution plate 2 and facilitating the processing of the annular gas distribution plate 2.

The third flange 13 and the fourth flange 251 abut against each other and are connected together, thereby increasing the contact area between the outer ring fire cover 1 and the lower cover assembly 25, thereby ensuring both the connection strength between the outer ring fire cover 1 and the lower cover assembly 25 and the sealing between the outer ring fire cover 1 and the lower cover assembly 25.

In other embodiments, the baffle protrusion 272 can also be installed with the upper cover assembly 26 by welding, clamping or connecting with fasteners.

[0055] The baffle protrusion 272 extends toward the lower cover assembly 25 and is set at an angle to the top surface of the outer ring fire cover 1, so that a certain buffer space is provided between the baffle protrusion 272 and the top surface of the outer ring fire cover 1 to facilitate the mixing of gas and air and reduce the possibility of the gas in the flow hole 271 directly flowing out of the first air outlet 11 of the outer ring fire cover 1, thereby further promoting the uniformity of the flame intensity and distribution of the outer ring fire cover 1.

One part enters the first air inlet channel 21, and then enters the inner ring fire cover 3, and passes out from the second air outlet 31 of the inner ring fire cover 3, and ignites the inner ring fire cover 3; the other part enters the gas channel 23, and is distributed to the outer ring channel 22 through the baffle plate 27, and then passes out from the first air outlet 11 of the outer ring fire cover 1, and ignites the outer ring fire cover 1 with the help of heat transfer from the inner ring fire cover 3.

[0066] In the embodiment of the utility model, the inner ring fire cover 3 and / or the outer ring fire cover 1 and / or the annular gas distribution plate 2 are made of stainless steel. The material of the burner 100 is usually required to have the characteristics of high temperature resistance, corrosion resistance, and non-deformation to adapt to the high temperature environment of the gas cooker during cooking. Therefore, the inner ring fire cover 3 and / or the outer ring fire cover 1 and / or the annular gas distribution plate 2 are generally made of materials such as copper or cast iron, or ceramic materials, which results in the inner ring fire cover 3 and / or the outer ring fire cover 1 and / or the annular gas distribution plate 2 being relatively expensive and often having a relatively large thickness. Therefore, in an embodiment of the utility model, the material of the inner ring fire cover 3 and / or the outer ring fire cover 1 and / or the annular gas distribution plate 2 is stainless steel, thereby ensuring the high temperature resistance and corrosion resistance of the inner ring fire cover 3 and / or the outer ring fire cover 1 and / or the annular gas distribution plate 2. On the other hand, the cost of the stainless steel material is relatively low, which helps to reduce the cost of the inner ring fire cover 3 and / or the outer ring fire cover 1 and / or the annular gas distribution plate 2. On the other hand, the stainless steel material can manufacture a thinner inner ring fire cover 3 and / or outer ring fire cover 1 and / or the annular gas distribution plate 2.

[0067] The utility model also proposes a gas stove, which includes a burner 100. The specific structure of the burner 100 refers to the above embodiment. Since the gas stove adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0068] The above are only exemplary embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields are included in the patent protection scope of the present invention.
