Description

Technical Field

[0001] This utility model relates to the field of stove ignition technology, and more specifically to a stove-mounted permaluminator ignition device. Background Technology

[0002] As a major global consumer of catering products, my country has a huge market for commercial kitchen equipment, with over 30 million stoves alone. It is worth noting that a large number of commercial stoves still use traditional manual ignition methods. This outdated design not only increases the workload of chefs but also affects the efficiency of kitchen operations. The promotion and application of continuous flame ignition systems can effectively solve this industry pain point. By achieving automatic continuous ignition, it not only frees up chefs' hands but also links with intelligent flameout protection systems to significantly improve the safety level of the kitchen.

[0003] The existing traditional stove ring design has smoke exhaust grooves, which can buffer the impact of pot explosions and stabilize the stove pressure. However, the waste heat utilization stove has eliminated the groove design in order to improve thermal efficiency, which leads to increased stove pressure and makes it very easy for the flame to go out. This will not only trigger the flameout protection and cause combustion interruption, but also affect the normal operation of the anti-dry burning function.

[0004] Therefore, in order to solve the above problems, this application provides a stove-mounted permanent flame ignition device. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a stove-mounted permablaze ignition device to solve the problems existing in the background art.

[0007] Preferably, the positioning component includes a positioning sleeve, a first connecting hole, a vertical groove, and an annular groove. A second gas supply pipe is fixedly welded to the bottom of the positioning sleeve. The first connecting hole is provided at the bottom of the positioning sleeve, and the positioning sleeve is connected to the second gas supply pipe through the first connecting hole. Vertical grooves distributed in opposite directions are provided on the inner wall of the positioning sleeve, and an annular groove is provided at the bottom of the inner cavity of the positioning sleeve corresponding to the bottom of the vertical groove.

[0008] Preferably, the gas assembly includes a gas head, gas holes, corner edges, a positioning tube, a second connecting hole, and protrusions. The gas head has evenly distributed gas holes on its sidewalls, a corner edge at its top edge, a positioning tube at its lower end, and a second connecting hole at the middle of the lower end of the positioning tube. The second connecting hole communicates with the gas holes through the positioning tube. The lower edge of the positioning tube has opposing protrusions. When the internal pressure of the stove is too high, the circulating threaded groove design of the inner tube of the positioning tube allows the injected gas to form a... The vortex provides strong stability, and the multiple gas holes on the gas head can disperse the gas flow, reduce local flow velocity, and reduce pressure fluctuations while avoiding backfire or flameout. After long-term use, a certain amount of combustion residue will accumulate on the upper part of the positioning sleeve and the second gas supply pipe. At this time, the gas component can be rotated to make the protrusion rotate to the corresponding vertical groove, and the gas component can be pulled out upwards. The positioning sleeve and the inner tube of the second gas supply pipe can be cleaned by the cleaning rod. The protrusion has the same horizontal width as the vertical groove and the same vertical height as the annular groove.

[0009] Preferably, the auxiliary components include a fixing plate, a flame probe, an ignition needle, and a heat-insulating ceramic sleeve. The fixing plate is fixedly installed in the middle of the positioning sleeve. The flame probe and the ignition needle are both wrapped with heat-insulating ceramic sleeves, which are fixedly installed on the fixing plate. The extension end of the flame probe extending beyond the heat-insulating ceramic sleeve is located on the left side of the gas head, and the extension end of the ignition needle extending beyond the heat-insulating ceramic sleeve is located on the right side of the gas head and close to the gas orifice. At this time, the flame probe monitors the real-time combustion temperature, and the heat-insulating ceramic sleeve ensures that the connection between the middle of the flame probe and the ignition needle and the fixing plate will not experience thermal expansion and contraction due to excessive temperature, thus preventing the connection with the fixing plate from becoming loose. The outer diameter of the positioning tube is the same as the inner diameter of the positioning sleeve.

[0010] Preferably, the ash stacking assembly includes an ash stacking box, a third connecting hole, a threaded fixing sleeve, and a sealing cap. The ash stacking box is fixedly welded to the lower end of the second gas supply pipe. The upper end of the ash stacking box has a third connecting hole, and the ash stacking box is connected to the second gas supply pipe through the third connecting hole. The lower end of the ash stacking box has a threaded fixing sleeve, and the sealing cap is threadedly engaged with the lower side of the threaded fixing sleeve. During cleaning, the ash will fall into the ash stacking assembly through the second gas supply pipe. Subsequently, the sealing cap can be unscrewed downwards to remove the ash accumulated in the ash stacking assembly.

[0011] The technical effects and advantages of this utility model are as follows: The circulating threaded groove design of the inner tube of the positioning tube allows the injected gas to form a vortex in the middle, which has strong stability. The multiple gas holes opened on the gas head can disperse the gas flow, reduce the local flow velocity, reduce pressure fluctuations, and avoid backfire or flameout. At the same time, the detachable design of the positioning component and the gas component can clean the accumulated slag inside into the slag stacking component to avoid gas blockage.

A positioning tube 304 is located at the lower end of the gas head 301. A second connecting hole 305 is located in the middle of the lower end of the positioning tube 304, connecting to the gas holes 302 via the positioning tube 304. Opposite protrusions 306 are located at the lower edge of the positioning tube 304. When the pressure inside the stove is too high, the positioning tube 304... The circulating threaded groove design of the inner tube allows the injected gas to form a vortex in the middle, which has strong stability. At the same time, the multiple gas holes 302 opened on the gas head 301 can disperse the gas flow, reduce the local flow velocity, reduce pressure fluctuations, and avoid backfire or flameout. After long-term use, a certain amount of combustion residue will accumulate on the upper part of the positioning sleeve 201 and the second gas supply pipe 103. At this time, the gas component 3 can be rotated so that the protrusion 306 is rotated to the corresponding vertical groove 203, and the gas component 3 can be pulled out upwards. The positioning sleeve 201 and the inner tube of the second gas supply pipe 103 can be cleaned by cleaning rod. Reference Figure 2 and Figure 5The auxiliary component 4 includes a fixing plate 401, a flame probe 402, an ignition needle 403, and a heat-insulating ceramic sleeve 404. The fixing plate 401 is fixedly installed in the middle of the positioning sleeve 201. The middle of the flame probe 402 and the ignition needle 403 are both wrapped with heat-insulating ceramic sleeves 404.

The extension end of the flame probe 402 extending out of the heat-insulating ceramic sleeve 404 is located on the left side of the gas head 301. The extension end of the ignition needle 403 extending out of the heat-insulating ceramic sleeve 404 is located on the right side of the gas head 301 and is close to the gas hole 302. At this time, the flame probe 402 monitors the real-time combustion temperature. The heat-insulating ceramic sleeve 404 can ensure that the connection between the middle of the flame probe 402 and the ignition needle 403 and the fixing plate 401 will not experience thermal expansion and contraction due to excessive temperature, thus preventing the connection with the fixing plate 401 from becoming loose. Reference Figure 2 and Figure 6 The ash stacking assembly 5 includes an ash stacking box 501, a third connecting hole 502, a threaded fixing sleeve 503, and a sealing cover 504.

The lower end of the ash stacking box 501 has a threaded fixing sleeve 503, and the sealing cover 504 is threadedly engaged with the lower side of the threaded fixing sleeve 503. During cleaning, the ash will fall into the ash stacking assembly 5 through the second gas supply pipe 103. Subsequently, the sealing cover 504 can be unscrewed downwards to remove the ash accumulated in the ash stacking assembly 5.

[0021] The working principle of this utility model is as follows: When using this device, the entire device is installed at the bottom of the stove via a fixing plate 401. A detector is connected to the lower end of the flame probe 402, and an ignition controller is connected to the lower end of the ignition needle 403. A gas pipe is connected to the connecting valve 102. During ignition, gas is input into the second gas pipe 103 through the first gas pipe 101 and enters the positioning sleeve 201 through the first connecting hole 202, and then exits through the gas hole 302. At this time, the ignition controller controls the ignition needle 403 to ignite, and the gas exiting through the gas hole 302 is ignited. The flame probe 402 monitors the real-time combustion temperature. The heat-insulating ceramic sleeve 404 ensures that the connection between the middle of the flame probe 402 and the ignition needle 403 and the fixing plate 401 will not experience thermal expansion and contraction due to excessive temperature, thus preventing loosening of the connection. In case of excessive pressure inside the stove... The circulating threaded groove design of the inner tube of the positioning tube 304 allows the injected gas to form a vortex in the middle, which has strong stability. At the same time, the multiple gas holes 302 opened on the gas head 301 can disperse the gas flow, reduce the local flow velocity, reduce pressure fluctuations, and avoid backfire or flameout. After long-term use, the upper part of the positioning sleeve 201 and the second gas supply pipe 103 will accumulate a certain amount of combustion residue due to their proximity to the burner head, which will cause gas blockage. At this time, the gas component 3 can be rotated so that the protrusion 306 is rotated directly below the corresponding vertical groove 203, and the gas component 3 can be pulled out upwards. The positioning sleeve 201 and the inner tube of the second gas supply pipe 103 can be cleaned by the cleaning rod. The cleaned combustion residue falls into the slag accumulation component 5 through the second gas supply pipe 103. Subsequently, the sealing cap 504 can be unscrewed downwards to remove the combustion residue accumulated in the slag accumulation component 5.
