[0023] Figure 6 This is an enlarged view of embodiment A of the present invention. Detailed Implementation
[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0025] See Figures 1-6 This suspended anti-dry-burning burner includes a base 1 and a flame distribution seat 2. The flame distribution seat 2 has an outer ring flame distribution chamber 21, an inner ring flame distribution chamber 22, and a central flame distribution chamber 23. A supplementary air chamber 24 is formed between the outer ring flame distribution chamber 21 and the inner ring flame distribution chamber 22. The base 1 is provided with an outer ring air inlet 11, an inner ring air inlet 12, and a central air inlet 13 that are respectively connected to the outer ring flame distribution chamber 21, the inner ring flame distribution chamber 22, and the central flame distribution chamber 23. The three flames can be controlled independently, which can not only enable the equipment to have strong firepower, but also make the use of the suspended anti-dry-burning burner more flexible and convenient.
[0026] There is a gap between the bottom of the base 1 and the bottom of the flame distribution seat 2, forming an air inlet chamber 25. The air inlet chamber 25 is connected to the air supply chamber 24 and the central flame distribution chamber 23 respectively. When combustion begins above the flame distribution seat 2, a negative pressure is formed. The air in the air inlet chamber 25 will enter the combustion area through the air supply chamber 24 and the central flame distribution chamber 23 to participate in combustion. The air inlet chamber 25 can supplement the air supply chamber 24 and the central flame distribution chamber 23 with more air to participate in combustion, thereby improving the overall combustion efficiency of the equipment and reducing the chance of generating harmful gases.
[0027] Furthermore, the bottom of the burner seat 2 is provided with an outer ring air intake channel 26, an inner ring air intake channel 27, and a central air intake pipe 28, which are respectively connected to the outer ring burner chamber 21, the inner ring burner chamber 22, and the central burner chamber 23. The outer ring air intake channel 26, the inner ring air intake channel 27, and the central air intake pipe 28 are opened in the horizontal direction. The air intake ends of the outer ring air intake channel 26, the inner ring air intake channel 27, and the central air intake pipe 28 are aligned with the air outlet ends of the outer ring air intake section 11, the inner ring air intake section 12, and the central air intake section 13 in the horizontal direction and form a gap. When the gas enters the outer ring air intake channel 26, the inner ring air intake channel 27, and the central air intake pipe 28, it can drive the nearby air in, so that the gas and air are premixed in the outer ring air intake channel 26, the inner ring air intake channel 27, and the central air intake pipe 28 before participating in combustion.
[0028] Furthermore, the fire distribution seat 2 includes an upper seat plate 3 and a lower seat plate 4. The upper seat plate 3 and the lower seat plate 4 are fixed by riveting to form an outer ring air intake channel 26 and an inner ring air intake channel 27. The shapes of the outer ring air intake channel 26 and the inner ring air intake channel 27 are relatively complex. The processing difficulty of the outer ring air intake channel 26 and the inner ring air intake channel 27 can be simplified by riveting the upper seat plate 3 and the lower seat plate 4.
[0029] The central air intake pipe 28 is integrally formed with the lower base plate 4 or the upper base plate 3. Since the airflow output from the central air intake pipe 28 is concentrated in the central flame distribution chamber 23, the shape and structure of the central air intake pipe 28 are relatively simple. By integrally forming, the overall width of the central air intake pipe 28 can be reduced, which is conducive to increasing the area of the air intake holes on the flame distribution chamber 2 corresponding to the periphery of the central air intake pipe 28. This is beneficial to increase the amount of air supplied during combustion in the central flame distribution chamber 23, and further improve the combustion efficiency of the central flame distribution chamber 23.
[0030] Furthermore, the upper ends of the outer ring air intake 11, the inner ring air intake 12, and the central air intake 13 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 11, the inner ring air intake 12, and the central air intake 13, together with the support, enable the base 1 to support the ignition seat 2.
[0031] Furthermore, the upper end of the central air intake 13 is provided with a positioning recess 131, and the ignition seat 2 is provided with a positioning rib 29 corresponding to the positioning recess 131. The positioning rib 29 and the positioning recess 131 are fitted together to improve the installation accuracy between the base 1 and the ignition seat 2, making it easier for the air outlets of the outer ring air intake 11, the inner ring air intake 12 and the central air intake 13 to align with the air inlet ends of the outer ring air intake channel 26, the inner ring air intake channel 27 and the central air intake pipe 28.
[0032] Furthermore, the rear support includes several support columns 14, each with an upwardly protruding protrusion 141. A support step 142 is formed between the support column 14 and the protrusion 141. The ignition seat 2 abuts against the support step 142. The ignition seat 2 has a positioning hole 20 corresponding to the protrusion 141. The protrusion 141 and the positioning hole 20 are inserted and engaged, which can ensure the overall support effect of the base 1 on the ignition seat 2 and further improve the installation accuracy of the base 1 and the ignition seat 2.
[0033] Furthermore, the inner side of the support column 14 is provided with a hollow cavity 143 for installing an ignition needle or a thermocouple. The hollow cavity 143 extends from the upper end of the protrusion 141 to the lower end of the support column 14. The positioning insertion hole 20 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 143 first and then install and fix the base 1 and the ignition base 2, thereby improving the assembly efficiency.
[0034] Furthermore, the base 1 is connected to a telescopic temperature probe 5, which has a temperature measuring part 51. The temperature measuring part 51 extends from the central flame chamber 23 to the top of the flame base 2. The telescopic temperature probe 5 can measure the temperature of the bottom of the pot through the temperature measuring part 51. When the temperature is higher than the preset temperature value, an alarm can be issued through an external control device or the working state of the suspended anti-dry burning burner can be controlled, thereby achieving the anti-dry burning effect and improving the safety of the equipment.
[0035] Furthermore, the telescopic temperature probe 5 is provided with a mounting ear 52, which abuts against the bottom outer side of the base 1 and is fixed by a screw device, which facilitates the quick assembly of the telescopic temperature probe 5.
[0036] 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.
