Technical Field

[0001] This utility model relates to the technical field of gas equipment, specifically to a suspension burner. Background Technology

[0002] Suspension burners are widely used in gas stoves, which can improve cooking efficiency and quality.

[0003] Suspension burners typically feature an upward-facing central flame tube, allowing for increased central heat and stir-frying effects when needed. However, because the flame outlet is located at the bottom of the cookware, liquid overflowing from the cookware can flow into the central flame tube, potentially causing blockages.

[0004] Therefore, further improvements are needed. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a suspension burner that allows the liquid flowing into the high-power nozzle to be discharged outward through the central gas supply pipe, reducing the chance of blockage in the high-power nozzle and improving the reliability of the product.

[0006] The purpose of this utility model is achieved as follows:

[0007] A suspended burner includes a base and a flame distribution seat. A high-powered nozzle is located at the center of the flame distribution seat.

The air outlets of the outer ring air inlet and the inner ring air inlet are aligned horizontally with the outer ring ignition chamber and the inner ring ignition chamber, forming a gap.

[0010] As a specific embodiment, the ignition base includes an upper ignition plate and a lower ignition plate. The outer ring ignition chamber and the inner ring ignition chamber each include a corresponding outer ring air intake channel and an inner ring air intake channel. The upper ignition plate and the lower ignition plate are fixed by riveting to form the outer ring air intake channel and the inner ring air intake channel. The central air supply pipe is integrally formed with the lower ignition plate or the upper ignition plate.

[0011] As a specific embodiment, the base is provided with corresponding protrusions below the air outlets of the outer ring air inlet, inner ring air inlet, and central air inlet.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] First embodiment:

[0029] See Figures 1-7This suspended burner includes a base 1 and a flame distribution seat 2. A high-power nozzle 3 is provided at the center of the flame distribution seat 2. The inner side of the high-power nozzle 3 has a high-power channel 31. The bottom of the high-power nozzle 3 is connected to a central gas supply pipe 4, which extends horizontally. A central air inlet 11 is provided on the base 1. The outlet of the central air inlet 11 is aligned with the inlet of the central gas supply pipe 4 in the horizontal direction and forms a gap. When the gas is ejected from the outlet of the central air inlet 11, it can drive the surrounding air into the central gas supply pipe 4 at the same time. Moreover, the liquid in the central gas supply pipe 4 will not come into contact with the outlet of the central air inlet 11.

[0030] The outlet of the central gas pipe 4 is located vertically below the flame channel 31. The central gas pipe 4 is provided with a central gas delivery chamber 41. The central gas delivery chamber 41 is in the shape of a trumpet with its width increasing towards the central air intake 11. The shape of the central gas delivery chamber 41 can increase the flow speed of the gas mixture, so that the gas mixture can be discharged from the outlet of the flame nozzle 3 at high speed. The central gas delivery chamber 41 can not only increase the speed of the airflow entering the flame nozzle 3, but also discharge the liquid below the flame nozzle 3 through the air intake of the central air intake 11, thereby reducing the chance of liquid accumulating in the flame nozzle 3 or the central air intake 11 and causing blockage, and improving the reliability of the product operation.

[0031] Furthermore, a flame cap is connected to the upper side of the flame holder 2.

[0032] Furthermore, the ignition base 2 is provided with an outer ring ignition chamber 21 and an inner ring ignition chamber 22 arranged concentrically. The outer ring ignition chamber 21, the inner ring ignition chamber 22 and the high-power nozzle 3 are distributed from the outside to the inside, so that the suspension burner can have the effect of three-ring fire operation.

[0033] The ignition base 2 is provided with corresponding air inlets 23 at the positions between the outer ring ignition chamber 21 and the inner ring ignition chamber 22, and at the positions between the inner ring ignition chamber 22 and the high-power nozzle 3. The air inlets 23 penetrate the ignition base 2 vertically. When the gas is ejected and burned from the outer ring ignition chamber 21 and the inner ring ignition chamber 22, a negative pressure is generated, which allows the gas below the ignition base 2 to flow upward to the combustion position through the air inlets 23, thereby supplementing more air for combustion. This achieves the effect of supplementing air from the top, increasing the thermal efficiency of the product. More air entering the high-power nozzle 3 can increase the internal pressure of the high-power nozzle 3, thereby increasing the heat load of the high-power nozzle 3 during operation.

[0034] The base 1 is provided with an outer ring air inlet 12 and an inner ring air inlet 13, which correspond to the outer ring fire chamber 21 and the inner ring fire chamber 22, respectively. The air outlets of the outer ring air inlet 12 and the inner ring air inlet 13 are aligned horizontally with the outer ring fire chamber 21 and the inner ring fire chamber 22 and form a gap. The three rings can be controlled independently, making the use of the suspension burner more flexible and convenient.

[0035] Furthermore, the ignition base 2 includes an upper base plate 24 and a lower base plate 25. The outer ring ignition chamber 21 and the inner ring ignition chamber 22 respectively include corresponding outer ring air intake channels 211 and inner ring air intake channels 221. The upper base plate 24 and the lower base plate 25 are fixed by riveting to form the outer ring air intake channel 211 and the inner ring air intake channel 221. The shapes of the outer ring air intake channel 211 and the inner ring air intake channel 221 are relatively complex. The processing difficulty of the outer ring air intake channel 211 and the inner ring air intake channel 221 can be simplified by riveting the upper base plate 24 and the lower base plate 25.

[0036] The central gas supply pipe 4 is integrally formed with the lower base plate 25 or the upper base plate 24. Since the airflow output from the central gas supply pipe 4 is concentrated in the high-power nozzle 3, the shape and structure of the central gas supply pipe 4 are relatively simple. The integral forming method can reduce the overall width of the central gas supply pipe 4, which is conducive to increasing the area of ​​the air inlet 23 on the burner base 2 corresponding to the periphery of the central gas supply pipe 4. This is conducive to increasing the air supply during the combustion of the high-power nozzle 3 and further improving the combustion efficiency of the high-power nozzle 3.

[0037] Furthermore, corresponding bosses 14 are provided on the base 1 below the outlets of the outer ring air inlet 12, inner ring air inlet 13, and central air inlet 11, respectively. The bosses 14 are integrally formed with the base 1. The vertical projection of the boss 14 corresponding to the central air inlet 11 is offset from the vertical projection of the central air supply pipe 4 and forms a horizontal distance. The bosses 14 can improve the overall structural strength of the base 1. Moreover, when liquid drips from the central air supply pipe 4 onto the base 1, the bosses 14 can block the water from flowing to the outlets of the outer ring air inlet 12, inner ring air inlet 13, and central air inlet 11.

[0038] Furthermore, the upper ends of the outer ring air intake 12, the inner ring air intake 13, and the central air intake 11 are respectively located on the base 1 at the lower front side of the corresponding ignition seat 2. They abut against the bottom of the ignition seat 2. The base 1 is provided with a rear support at the lower rear side of the corresponding ignition seat 2. The rear support abuts against the ignition seat 2. The outer ring air intake 12, the inner ring air intake 13, and the central air intake 11, together with the support, enable the base 1 to support the ignition seat 2.

[0039] Furthermore, the upper end of the central air intake 11 is provided with a positioning recess 111, and the ignition seat 2 is provided with a positioning rib 26 corresponding to the positioning recess 111. The positioning rib 26 and the positioning recess 111 are fitted together to improve the installation accuracy between the base 1 and the ignition seat 2, making it easier for the air outlet of the central air intake 11 to align with the air inlet of the central air supply pipe 4.

[0040] Furthermore, the rear support includes several support columns 15, each support column 15 having an upwardly protruding protrusion 151. A support step 152 is formed between the support column 15 and the protrusion 151. The ignition seat 2 abuts against the support step 152. The ignition seat 2 has a positioning hole 27 corresponding to the protrusion 151. The protrusion 151 and the positioning hole 27 are inserted and matched, which can not only ensure the overall support effect of the base 1 on the ignition seat 2, but also further improve the installation accuracy of the base 1 and the ignition seat 2.

[0041] Furthermore, the inner side of the support column 15 is provided with a hollow cavity 153 for installing an ignition needle or a thermocouple. The hollow cavity 153 extends from the upper end of the protrusion 151 to the lower end of the support column 15. The positioning insertion hole 27 is set on the ignition base 2 at the position corresponding to the outer ring ignition cavity 21 and the inner ring ignition cavity 22. There is no need to open additional mounting holes for the ignition needle or thermocouple at other positions on the ignition base 2, which simplifies the structure of the ignition base 2. Workers can also install the ignition needle or thermocouple on the hollow cavity 153 first and then install and fix the base 1 and the ignition base 2, thereby improving the assembly efficiency.

[0042] Second embodiment:

[0043] See Figure 8 , Figure 9 The difference between this embodiment and the first embodiment is that the first end of the central gas delivery chamber 41 of this suspended burner corresponds to the air inlet end of the central air inlet 11, and the end of the central gas delivery chamber 41 extends to the vertical lower part of the high flame channel 31. The end of the central gas delivery chamber 41 forms a guide slope 411 at the position below the corresponding high flame channel 31. The guide slope 411 is inclined downward along the direction close to the central air inlet 11. After the liquid enters the lower part of the high flame channel 31, it can flow more quickly through the guide slope 411 to the central gas delivery chamber 41, and then be discharged outward through the air inlet end of the central gas delivery pipe 4. This can prevent the liquid from accumulating below the high flame channel 31 and further reduce the chance of liquid accumulating and blocking in the high flame channel 31.

[0044] The remaining undescribed parts are the same as in the first embodiment and will not be repeated here.

[0045] The above embodiments are merely preferred embodiments of this utility model, and other implementations are also possible. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model, and all such equivalent modifications or substitutions are included within the scope set forth in the claims of this application.
