Detailed Description

The following further description is made with reference to the drawings and specific embodiments.

As shown in fig. 3-5, the present embodiment provides a power-enhanced burner 100 with a reduced height, comprising a burner body 10 and a burner 20 disposed in the burner body 10, wherein the burner 20 has a flange 21, and a ring of laterally-pulled burner holes 22 are disposed on the flange 21 in an annular arrangement; a cavity 30 is formed between the furnace body 10 and the burner 20, the cavity 30 is communicated with an air inlet pipe 11 arranged below the furnace body 10, and the side-pull combustion holes 22 are communicated with the cavity 30; a fire pressing ring 40 is arranged above the burner 20, the fire pressing ring 40 is integrally cylindrical, and is covered on the outer side of the side-pull combustion hole 22, and the fire pressing ring 40 is movably embedded in the furnace body 10.

When the burner 100 is in operation, a combustible gas, which may be liquefied petroleum gas, natural gas or other civil gas, or a premixed gas of the civil gas and air mixed in a certain ratio, is introduced from the bottom of the burner 20 through an inlet pipe 50. The bottom of the burner 20 is provided with a burner head 23, and the combustible gas is ignited and burned at the burner head 23. The air inlet pipe 11 under the furnace body 10 is connected with a blower for introducing air, the air enters the interior of the combustor 20 through the air supplementing holes 24 arranged on the side wall of the combustor 20 to increase oxidation supply so as to enable the combustible gas to be more fully combusted, and the air enters the upper part of the combustor 20 through the side-pulling combustion holes 22 to further increase oxidation supply so as to enable gases such as the combustible gas which is not fully combusted or carbon monoxide generated by combustion to be further combusted.

As is well known, the combustible gas or carbon monoxide can be normally combusted under the condition of reaching a certain air-fuel ratio, if the combustible gas which is not combusted or the carbon monoxide which is generated due to insufficient combustion from the inside of the burner 20 directly contacts the outside, the combustible gas or the carbon monoxide may not be normally combusted due to no flame generation, but the side-pull combustion holes 22 of the embodiment are small holes which can take root for the flame, and the outer side of the side-pull combustion holes is provided with the fire pressing ring 40 which can isolate the excessive air from the outside to enable the air-fuel ratio at the position to meet the combustion condition, so that the fire pressing ring 40 and the side-pull combustion holes 22 just form a combustion area which can create the combustion condition for the combustible gas or the carbon monoxide, thereby achieving the effect of sufficient combustion and increasing the extra flame, thereby enhancing the power of the burner 100.

In this embodiment, the side pull combustion holes 22 are uniformly arranged along a circumference, and the radius of the circumference is smaller than the inner diameter of the flame pressing ring 40, so that the flame pressing ring 40 is located inside all the side pull combustion holes 22. Of course, in the other embodiments of the present invention, two or more circles of side-pulling combustion holes 22 may be provided, and these two or more circles of side-pulling combustion holes 22 are concentrically and alternatively disposed to further increase the area of flame, thereby enhancing the power of the furnace end of the present invention.

As shown in fig. 6, the fire ring 40 is provided with a flange 41, and the fire ring 40 is supported on the upper end surface of the furnace body 10 through the flange 41. The structure facilitates taking and placing of the fire suppression ring 40, and the height of the fire suppression ring 40 can be flexible without corresponding to the height of the combustor 20, so that the processing difficulty of the fire suppression ring 40 is reduced.

The inner wall of the flame pressing ring 40 of the present embodiment is in a gradually decreasing trumpet shape from bottom to top, and the minimum inner diameter of the flame pressing ring 40 is smaller than the radius of the ring where the side pull combustion holes 22 are located (if the side pull combustion holes 22 are two or more rings, the radius of the outermost ring is the radius). The purpose of this design is that the upper part of the fire pressing ring 40 can block the water, oil and vegetable residue falling from the upper part during cooking, and prevent the side-pull combustion hole 22 from being blocked due to falling.

In addition, a pilot device 60 is disposed beside the furnace body 10, and the flame generated by the pilot device 60 is suitable for igniting the combustible gas in the burner 20. Meanwhile, a notch 42 (see fig. 3 and 5) is formed downward from the upper end surface of the flame pressing ring 40, and the notch 42 corresponds to the position of the pilot burner 60 and guides the flame to the upper side of the burner 20. In general, in order to smoothly introduce the flame of the pilot device 60 into the burner 20, the burner of the pilot device 20 needs to be higher than the burner ring 40 and the upper end surface of the burner body 10, and in this embodiment, the notch 42 is provided so that the flame can be introduced into the burner 20 without raising the burner in order to further reduce the heights of the burner body 10 and the entire burner 100.

To sum up, the utility model discloses a set up the flame ring for cylindricly to inlay in the furnace body movably, reach the effect of reducing flame ring and furnace end height, make the whole height of furnace end basically the same with ordinary furnace end, thereby can reform transform ordinary furnace end, only need not originally to incline the combustor replacement cost of drawing the burner port with the combustor, in addition press the flame ring can, the whole size of replacement back furnace end is unchangeable basically, can not influence the normal use of original and supporting kitchen utensils and appliances of burning kitchen.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
