Description

Technical Field

[0001] The utility model relates to the technical field of gas stoves, in particular to a burner and a gas stove device. Background Art

[0002] A gas stove is a kitchen appliance that uses direct flame heating through the combustion of gas fuel. The burner, as an important component of a gas stove, mainly functions to mix fuel and air and ignite them to produce a flame. Multiple combustion holes are evenly distributed around the entire circumference of the burner, with the air inlet of the burner head located in the center. The fuel and air are mixed and diverted through the inlet flow duct inside the burner head, allowing the mixed gas to enter the outer ring cavity around the burner head, thereby providing gas for the combustion holes. The flow direction of the gas changes during the process of entering the outer ring cavity from the inlet flow duct, making it difficult to form a uniform left-right diversion when entering the outer ring cavity. This will cause uneven distribution of gas flow in different areas of the outer ring cavity, and the flame formed inside the combustion hole will burn unevenly, resulting in incomplete combustion and increased carbon monoxide emissions.

[0003] In addition, a pot stand is set above the burner. In order to prevent the temperature of the pot stand legs from being too high, resulting in defects such as de-enamelling and deformation, the burner is usually provided with a fire avoidance hole. The aperture of the fire avoidance hole is small, and the gas flow rate that can pass through it is small. Therefore, the location of the fire avoidance hole will further hinder the uniformity of the gas flow in the outer ring cavity. Utility Model Content

[0036] like Figure 1 and Figure 2 As shown, this embodiment first provides a burner, which includes an outer ring fire cover 1. The outer ring fire cover 1 is provided with a first combustion hole 11 and a fire avoidance hole 12. The aperture of the first combustion hole 11 is larger than the aperture of the fire avoidance hole 12. Therefore, the gas flow rate of the first combustion hole 11 is relatively large, forming a combustion flame. The gas flow rate of the fire avoidance hole 12 is relatively small, and the combustion temperature is low. The position of the fire avoidance hole 12 corresponds to the support leg of the pot rack (not shown in the figure), which can prevent the support leg of the pot rack from being peeled off, deformed, etc. due to the high combustion flame temperature and the large flame.

[0037] The burner also includes a fire distribution assembly 2, which includes a fire cover base 21 and a diverter cover 22 provided on the fire cover base 21. The fire distribution assembly 2 is provided with an air inlet 201, a guide channel 202 and an outer ring gas mixing channel 203. The air inlet 201 is connected to the ejector tube assembly 4. The ejector tube assembly 4 provides fuel gas and drives the air flow. The fuel gas and air enter the guide channel 202 through the air inlet 201 and mix during the flow. The outer ring gas mixing channel 203 is arranged on the circumference of the fire cover base 21. The outer ring gas mixing channel 203 can connect the first combustion hole 11 and the fire avoidance hole 12, and provide mixed gas to the first combustion hole 11 and the fire avoidance hole 12. The two ends of the guide channel 202 are respectively connected to the air inlet 201 and the outer ring gas mixing channel 203 to guide the fuel gas. The outlet end 2021 of the guide channel 202 is provided with a connecting seat 23. When the gas flows in the guide channel 202 to the outlet end 2021, it encounters the connecting seat 23 and is diverted along the direction of gas flow. The diverted gas enters the outer ring gas mixing channel 203 on both sides of the connecting seat 23, respectively, so that the gas flow to both sides is equal, improving the uniformity of the gas flow in the outer ring gas mixing channel 203. The first combustion hole 11 on the entire circumference of the outer ring fire cover 1 can form a relatively uniform flame, promote full combustion, and avoid increased carbon monoxide emissions. The connecting seat 23 is used to connect the fire cover base 21 and the diverter cover 22, or the connecting seat 23 is used to connect the fire distribution assembly 2 and the outer ring fire cover 1, to realize the assembly of the fire cover base 21 and the diverter cover 22 or to realize the assembly of the outer ring fire cover 1 on the fire distribution assembly 2. Connector 23 faces flame avoidance hole 12. Since the gas is diverted at connector 23, the gas flow rate at connector 23 is relatively low, meeting the small aperture requirement of flame avoidance hole 12 and preventing turbulence caused by sudden changes in gas flow at flame avoidance hole 12, which could affect the uniformity and smoothness of gas flow. Connector 23 has multiple functions: while achieving installation and connection, it can evenly divert gas flow and provide a flame avoidance function, improving the combustion quality of the burner.

[0038] The air inlet 201 is located at the center of the ignition distributor assembly 2. The inlet end 2022 of the flow channel 202 is connected to the air inlet 201. The flow channel 202 extends radially along the ignition distributor assembly 2. The width of the flow channel 202 gradually increases from the inlet end 2022 to the outlet end 2021. This gradually expands the width of the flow channel 202, forming a gradually expanding structure within the flow channel 202. This reduces gas pressure, minimizes pressure loss during gas flow, and ensures combustion quality.

[0039] In order to further increase the uniformity of gas flow distribution, the fire distribution assembly 2 is provided with multiple guide channels 202, which are evenly spaced along the circumference of the air inlet 201, and the outlet ends 2021 of the multiple guide channels 202 are all provided with connecting seats 23. Figure 3As shown, the fire distribution assembly 2 is provided with four guide channels 202, with four evenly spaced inlet ports 2022 formed around the air inlet 201. The four guide channels 202 are radially connected to the outer annular gas mixing channel 203 on the periphery. The gas in the four guide channels 202 is evenly distributed by the connector 23 at the outlet ports 2021, flowing into the outer annular gas mixing channels 203 on both sides of the connector 23, and is mixed within the outer annular gas mixing channels 203. Figure 3 The arrows in the middle indicate the direction of gas flow.

[0040] Specifically, the fire cover base 21 includes a base plate 211 and side panels 212 arranged around the base plate 211. The outer ring mixing channel 203 is opened on the base plate 211. The base plate 211 is also provided with a first groove, and the diverter cover 22 is provided with a second groove. When the diverter cover 22 is placed on the base plate 211, the first groove and the second groove are connected to form the guide channel 202. The connecting seat 23 is connected to the inner side wall of the side panel 212 and extends to the outlet end 2021, as shown in FIG. Figure 3 As shown, this can increase the structural strength of the connecting base 23 and prevent the connecting base 23 from being broken or damaged after long-term use.

[0041] In order to increase the smoothness of the gas flow, the inner groove wall 214 of the first groove is connected to the inner cavity wall 215 of the outer ring gas mixing channel 203, and the connection between the inner groove wall 214 and the inner cavity wall 215 has a transition arc surface 213 (refer to Figure 3 ), the diverted gas flows along the transition arc surface 213 to avoid excessive flow resistance and pressure loss when the diversion is turned.

[0042] The connector 23 has an arcuate side surface 231 that faces the inlet end 2022 of the flow guide channel 202, further reducing resistance to the gas flow. The connector 23 may be cylindrical, or at least partially cylindrical, and the present embodiment is not limited thereto.

[0043] In one embodiment, the connecting seat 23 is used to realize the assembly of the fire cover base 21 and the diverter cover 22. Specifically, the connecting seat 23 includes a first mounting column 232 and a second mounting column 233. The first mounting column 232 is arranged on the fire cover base 21, and the second mounting column 233 is arranged on the diverter cover 22. The first fastener (not shown in the figure) passes through the first mounting column 232 and is connected to the second mounting column 233. The connecting seat 23 realizes the installation of the diverter cover 22 on the fire cover base 21. The outer ring fire cover 1 is connected to the fire separation assembly 2 to cover the outer ring gas mixing channel 203 to ensure the sealing of the outer ring gas mixing channel 203. The gas in the outer ring gas mixing channel 203 enters the first combustion hole 11 and the fire avoidance hole 12. The fire avoidance hole 12 is located above the second mounting column 233. A small amount of gas around the connecting seat 23 can meet the combustion requirements of the fire avoidance hole 12.

[0044] In order to realize the installation of the outer ring fire cover 1, the diverter cover 22 further includes a plurality of third installation columns 221, such as Figure 4 As shown; the outer ring fire cover 1 also includes a plurality of fourth mounting columns 13, and the plurality of fourth mounting columns 13 correspond one to one with the plurality of third mounting columns 221. The second fastener (not shown in the figure) passes through the third mounting columns 221 and is connected to the fourth mounting columns 13, so as to realize the installation of the outer ring fire cover 1 on the fire distribution assembly 2. The outer ring fire cover 1 is provided with a plurality of fire avoidance holes 12, and the plurality of fire avoidance holes 12 and the plurality of fourth mounting columns 13 are arranged in a staggered manner. As shown Figure 5 As shown in the figure, the outer ring fire cover 1 is provided with four fire avoidance holes 12 and four fourth mounting posts 13. The four fire avoidance holes 12 and the four fourth mounting posts 13 are staggered and spaced apart in sequence. This connection structure in which the first fastener and the second fastener are staggered can disperse the force and avoid deformation of the fire separation assembly 2 caused by the concentration of the tightening torque. In actual assembly, the diverter cover 22 and the outer ring fire cover 1 can be connected from bottom to top by the second fastener, and then the diverter cover 22 can be installed on the fire cover base 21 from bottom to top by the first fastener.

[0045] In one embodiment, the burner further includes an inner ring fire cover 3, which is arranged above the diverter cover 22 to form an inner ring gas mixing chamber 204. The second combustion hole 31 on the inner ring fire cover 3 is connected to the inner ring gas mixing chamber 204 to form an inner ring flame. The inlet of the inner ring gas mixing chamber 204 is connected to the air inlet 201, and the fuel gas enters the annular inner ring gas mixing chamber 204 through the inlet to provide fuel gas to the second combustion hole 31. The fire separation assembly 2 has a supplementary air intake channel 205 that runs through the axial direction. The supplementary air intake channel 205 is opened between two adjacent guide channels 202. The supplementary air intake channel 205 is arranged around the circumference of the inner ring fire cover 3. The supplementary air intake channel 205 is used to guide supplementary air. The supplementary air can participate in the combustion of the first combustion hole 11 and the second combustion hole 31 to avoid incomplete combustion.

[0046] The embodiment of the present invention secondly provides a gas stove device, which includes the burner in any of the above embodiments, and further includes an ejector tube assembly 4. The ejector tube assembly 4 ejects gas and drives air flow, and the gas and air simultaneously enter the air inlet 201 of the fire distribution assembly 2 and flow and mix in the guide channel 202. The fire distribution assembly 2 of the burner is provided with a connecting seat 23 at the outlet end 2021 of the guide channel 202, and the connecting seat 23 faces the fire avoidance hole 12 of the outer ring fire cover 1. The connecting seat 23 has multiple functions. While achieving installation and connection, it can evenly divert the gas and improve the uniformity of the gas flow in the outer ring mixing channel 203. The connecting seat 23 also has a fire avoidance function, which meets the small aperture requirement of the fire avoidance hole 12, avoids the turbulence caused by the sudden change of the gas flow at the fire avoidance hole 12 from affecting the uniformity and smoothness of the gas flow, and improves the combustion quality of the gas stove device.
