Description

The burner adopts the combined combustion technology of external direct fire and internal swirling fire

technical field

The utility model relates to the field of cooking utensils, in particular to a burner which adopts the combined combustion technology of external direct fire and internal swirling fire.

Background technique

Atmospheric burners for cookers currently in the market are arranged in a variety of fire holes, but they are roughly divided into two fire types: direct fire and swirling fire. These two fire types have their own advantages and disadvantages. The direct fire is easy to contact with the secondary air and burns fully. , but the single straight fire flame belongs to laminar flow combustion, the flame burning speed is slow, and the combustion temperature is low, so the efficiency is lost. Air is not easy to supply, and the range of adaptation is relatively smaller than that of direct fire combustion.

Contents of the invention

The utility model aims to solve the shortcomings of the above-mentioned prior art, and provides a burner using the combined combustion technology of external direct fire and internal swirling fire, which is a high-efficiency and energy-saving combustion device. This burner focuses on taking the advantages of the two and optimizing the burner , under the limited fire distribution area, reasonably distribute the position and ratio of the two, and maximize the distribution fire hole area to achieve the optimal heat intensity of the bottom of the pot. Thereby greatly improving the thermal efficiency of the burner. Improve energy utilization and reduce harmful gas emissions.

The technical scheme adopted by the utility model to solve its technical problems: this kind of burner adopting the combined combustion technology of external direct fire and internal swirling fire mainly includes a small firearm, a large firearm and a base, and the outer ring of the large firearm is provided with The upper fire holes on the outer ring and the lower fire holes on the outer ring, the two rows of round fire holes are arranged in a large and small arrangement, and the upper fire holes in the outer ring are arranged at intervals in the middle of the two lower fire holes in the outer ring; The inner ring of the Oita firearm described above is provided with an inner ring fire hole of a serrated hole, and forms a negative pressure spiral air-mixing channel along the center of the circle.

As a preference, the fire hole angle of the upper fire hole on the outer ring and the lower fire hole on the outer ring is 40 degrees along the vertical direction; the fire holes on the inner ring are arranged horizontally and vertically.

The beneficial effect of the utility model is: adopting the arrangement of the outer straight fire, the inner rotation fire and the double row of fire hole arrangement of the fire core, finally forming a flat flame combustion effect.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in Figure 1-3, this kind of burner adopting the combined combustion technology of external direct fire and internal swirling fire mainly includes a small firearm 1, a large firearm 2 and a base 3, and the outer ring of the large firearm 2 is provided with The upper fire discharge hole 2-1 of the outer ring and the lower fire discharge hole 2-2 of the outer ring. The middle positions of the holes 2-2 are arranged at intervals; the inner ring of the Oita firearm 2 is provided with an inner ring fire hole 2-3 of tooth-shaped holes, and forms a negative pressure spiral air-mixing channel along the center of the circle. The fire hole angle of the upper fire hole 2-1 on the outer ring and the lower fire hole 2-2 on the outer ring is 40 degrees in the vertical direction; the fire hole 2-3 in the inner ring is 30 degrees in the horizontal direction, and The direction is arranged at 45 degrees.

The burner rationally optimizes the structure of the traditional burner head, pays attention to the key structural dimensions, re-optimizes the design of the burner head, and uses the negative pressure spiral gas mixing channel to reduce the channel resistance and enhance the air ejection and mixing capabilities; Reasonable design of channel structure, channel area and location; reasonable distribution of secondary air supply channels under the condition of sufficient gas channels, rational use of limited space, and try to meet the balanced combustion of secondary air required by all fire holes, large firearms, and small firearms , through verification and calculation, the reasonable distribution size is divided into the size and position of the fire hole of the firearm, and finally the three-dimensional balanced combustion is realized.

In addition to the above embodiments, the utility model can also have other implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the utility model.
