Description

Technical Field

[0001] The utility model relates to the technical field of combustion burners, and more specifically to a double-fire-divider combustion burner. Background Art

[0002] A premix burner is one that premixes gas and air in proportion and then sprays and burns it through high-voltage electronic ignition. Its advantages are high thermal efficiency and safety, and it is very common in commercial use.

[0003] Patent ZL201621220003.7 describes an efficient and silent double-rotation premix burner, which includes a high-temperature fire concentrating ring, an inner and outer double-rotation burner, a stainless-steel fire cap, a burner housing, a standing pilot tube, an ignition needle, a variable swirl number swirler, a standing pilot joint, a mixing air device, a main gas joint, a fixing nut, a heat collecting probe, a sealing gasket, a heat conducting tube, a heat insulating cotton, a heating coil, and a water tank.

[0004] In actual use, it can also be optimized in the following three aspects: (1) There is no obvious distinction between large and small combustion fire powers, only a large fire. In different cooking processes, sometimes chefs also need to use a small fire. (2) The standing pilot can quickly ignite the burner, enabling the large fire to be opened at any time. However, sometimes the airflow generated when the chef lifts or presses the pot can cause the standing pilot to go out, losing its value as a kindling. (3) The inner and outer double-rotation burner, more specifically the fire divider, can also be configured with a better type of fire divider to achieve the most ideal silent effect. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the above defects of the prior art and provide a double-fire-divider combustion burner, which has large and small fires with different combustion fire powers and can meet the different combustion fire powers required by different cooking processes; it is equipped with a double insurance kindling of a standing pilot and a small fire, which can quickly ignite the burner, thereby ensuring that the large fire can be opened at any time; it selects a laminated fire divider, which has more evenly distributed holes and a larger cross-sectional area of gas output, and the environmental protection and silent effect are more ideal.

[0006] To achieve the above object, the present utility model is realized through the following technical solutions: A double-division fire burner combustion furnace head, characterized in that it includes a furnace head outer shell, an inner bottom of the furnace head outer shell is provided with a furnace head inner shell, a small fire combustion chamber is formed in the furnace head inner shell, a small fire divider is implanted in the small fire combustion chamber, a large fire combustion chamber is formed in the upper part of the furnace head outer shell in the furnace head outer shell, a large fire divider is implanted in the large fire combustion chamber, the large fire divider and the small fire divider are laminated dividers with the same structure but different sizes, a large fire intake cavity is formed between the outer wall of the large fire divider and the upper inner wall of the furnace head outer shell, a large fire gas guiding cavity is formed between the lower inner wall of the furnace head outer shell and the outer wall of the furnace head inner shell, the large fire intake cavity is communicated with the large fire gas guiding cavity through a plurality of equally spaced distribution air guide holes, the lower part of the large fire gas guiding cavity is communicated with a large fire mixing cavity, a small fire intake cavity is formed between the outer wall of the small fire divider and the inner wall of the furnace head inner shell, the lower part of the small fire intake cavity is communicated with a small fire gas guiding cavity, and the side of the small fire gas guiding cavity is communicated with a small fire mixing cavity. A constant fire combustion chamber is hung on the outer wall of the furnace head outer shell, an ignition needle and a constant fire burner cap are arranged in the constant fire combustion chamber, and a constant fire mixing cavity is connected below the constant fire burner cap.

[0007] The present utility model has large and small fires with different combustion powers, which can meet the different combustion powers required for different cooking processes; it is equipped with a double insurance of constant fire and small fire, which can quickly ignite the burner, thus ensuring that the large fire can be opened at any time; it selects a laminated divider, which has more evenly distributed holes and a larger cross-sectional area of gas outlet, and the environmental protection and noise reduction effects are more ideal.

[0008] Preferably, the small fire gas guiding cavity is received in the large fire mixing cavity, and the small fire mixing cavity penetrates into the large fire mixing cavity from the side and then is communicated with the small fire gas guiding cavity.

[0009] Preferably, a ventilation hole communicated with the large fire mixing cavity is provided on the small fire gas guiding cavity. The air flow power of the large fire combustion is much larger than that of the small fire combustion, so the air flow pressure of the large fire combustion entering will hinder the air flow pressure of the small fire combustion, making the air flow pressure of the small fire unable to enter normally. Opening this ventilation hole stabilizes this positive pressure area and balances the air flow.

[0010] Preferably, the constant fire mixing cavity is communicated with the small fire mixing cavity. As long as the constant fire and the small fire meet the small air flow combustion and ensure that the ignition source does not go out, they can supply gas with the same air flow power.

[0011] Preferably, the laminated flame distributor includes an upper fixed ring plate and a lower fixed ring plate. Between the upper fixed ring plate and the lower fixed ring plate, a number of wavy ring plates and flat circular ring plates are laminated alternately up and down. Among them, the horizontal direction of the wavy ring plate is in a wavy shape, and the horizontal direction of the flat circular ring plate is in a plane. The laminated flame distributor has holes with more uniform distribution and a larger air output with a cross-sectional area, and the environmental protection and noise reduction effects are more ideal.

[0012] Preferably, a number of equally spaced large-fire partition plates are provided on the inner wall of the burner housing. The large-fire partition plates divide the large-fire air inlet cavity and the large-fire air guiding cavity into corresponding numbers of large-fire air flow chambers according to the number of the air guide holes. The large-fire air flow chambers are evenly divided, so that the large-fire supply air flow is more uniform, which can further reduce noise and ensure the stability of the flame at the same time.

[0013] Preferably, a number of equally spaced small-fire partition plates are provided on the inner wall of the inner burner housing. The small-fire partition plates divide the small-fire air inlet cavity into a number of small-fire air flow chambers. The small-fire air flow chambers are evenly divided, so that the large-fire supply air flow is more uniform, which can further reduce noise and ensure the stability of the flame at the same time.

[0014] Beneficial effects: The utility model has large and small fires with different combustion powers, which can meet the different combustion powers required by different cooking processes; it is equipped with a double insurance of a constant open fire and a small fire, which can quickly ignite the burner, so as to ensure that the large fire can be opened at any time; it selects a laminated flame distributor, which has holes with more uniform distribution and a larger air output with a cross-sectional area, and the environmental protection and noise reduction effects are more ideal.
