In this embodiment, the butt joint structure of the outer ring fire cover 2 and the base 1 is adopted.
An outer liquid storage tank 3 extending inwards from the wall surface of the outer ring gas mixing chamber along the circumferential direction is arranged on the inner ring wall of the outer ring gas mixing chamber, and the outer liquid storage tank 3 is annular. The position of the external liquid tank 3 is specifically set according to the requirement, and the external liquid tank 3 can be arranged on the outer surface of the inner ring wall of the outer ring fire cover 2 and also can be arranged on the outer surface of the inner connecting wall of the base 1. The external liquid storage tank 3 in this embodiment is specifically connected to the inner annular wall of the outer annular fire cover 2. Specifically, an annular plate 31 is connected to the inner annular wall of the outer annular gas mixing chamber along the circumferential direction, and the plate 31 gradually inclines upwards from outside to inside along the radial direction, so that the outer liquid storage tank 3 is formed between the plate 31 and the inner annular wall of the outer annular gas mixing chamber. When the top surface of the outer ring fire cover 2 has the overflow, the overflow flows to the inner ring surface of the outer ring fire cover 2 along the inclined direction of the top surface of the outer ring fire cover 2, and then flows to the outer liquid storage tank 3 along the inner ring wall of the outer ring gas mixing chamber, so that the probability that the outer fire hole 20 is blocked by the overflow is reduced. In addition, the inclined arrangement mode of the top wall of the outer ring fire cover 2 in the embodiment is favorable for gathering flue gas, so that the flue gas can be fully and effectively contacted with the bottom of a pot above the combustor, and the heat efficiency is improved.
In order to further prevent the overflowing liquid flowing outwards from the edge of the top surface of the outer ring fire cover 2 from blocking the outer fire hole 20, the structure of the outer ring fire cover 2 is improved in the embodiment. Specifically, the outer ring fire lid 2 includes a fire lid base 21 and a top plate 22 disposed above the fire lid base 21, and a top surface of the top plate 22 constitutes a top surface of the outer ring fire lid 2, that is, the top surface of the top plate 22 is gradually inclined downward from an outer edge to a center direction. The top plate 22 is connected to the upper surface of the fire lid base body 21 through the supporting block 23, and a gap 24 is formed between the top plate 22 and the fire lid base body 21. In order to ensure the firmness of supporting the top plate 22, at least two supporting blocks 23 may be provided, and the two supporting blocks 23 are uniformly arranged along the circumferential direction of the fire cover base body 21. In the present embodiment, four support blocks 23 are provided, and the included angle between every two support blocks 23 is 90 °.
The outer peripheral edge of the top plate 22 is located above the upper surface of the fire lid base 21, and the inner peripheral edge of the top plate 22 is located above the outer liquid reservoir 3. Thus, the gap 24 between the top plate 22 and the fire lid base body 21 not only can form a channel for the external air to enter, but also can be used as a guide channel for the outflow overflow, in this embodiment, the upper surface of the fire lid base body 21 gradually inclines downwards from the outer edge to the center direction, so that the overflow drops on the upper surface of the fire lid base body 21 after flowing outwards from the outer edge of the top plate 22, and then the overflow flows into the external liquid tank 3 along the upper surface of the fire lid base body 21 and the inner ring wall of the outer ring gas mixing chamber, thereby preventing the overflow from flowing into the external fire holes 20 and blocking the external fire holes 20. The outer ring fire cover 2 of this structure not only can initiatively inwards drain the overflow, can also inwards drain the overflow of outflow for outer fire hole 20 prevents blockking up the effect better.
An annular secondary air supply passage 200 for supplying secondary air is defined between the outer and inner air mixing chambers 500. The base 1 is provided with a secondary air introduction passage 300 radially communicating with the secondary air supply passage 200, the secondary air introduction passage 300 is isolated from the outer ring air mixing chamber, and when in use, external air enters the secondary air supply passage 200 through the secondary air introduction passage 300 to supply secondary air to the inner sides of the inner ring flame and the outer ring flame. However, after the air enters the secondary air supply passage 200 from the secondary air introduction passage 300, since there is no guide member, the air is in a freely diffused state, and there is no pertinence in supplying the secondary air required for flame combustion, which is not favorable for sufficient combustion.
In the present embodiment, in order to improve the sufficiency of combustion at the internal fire holes 40, the external liquid sump 3 is provided above the secondary air introduction passage 300, and the outer peripheral wall of the external liquid sump 3 extends obliquely upward of the internal fire holes 40. While the outer peripheral wall of the inner liquid storage tank 5 is disposed facing the secondary air introduction passage 300, and the outer peripheral wall of the inner liquid storage tank 5 is gradually inclined upward of the inner fire holes 40 from the outside inward in the radial direction. So this outer periphery wall of depositing cistern 3 constitutes a passageway to interior fire hole 40 direction secondary air with the periphery wall of depositing cistern 5 jointly, and the air admission secondary air channels 300 back, then by the direction of direct guidance to interior fire hole 40, has reduced secondary air's flow resistance, does benefit to the abundant burning of interior fire hole 40 department flame, reduces the production of flue gas.
However, if the air is directed directly to the direction of the inner fire hole 40, the supply of the secondary air to the inside of the outer flame generated from the outer ring fire cover 2 is reduced. In order to solve this problem, the secondary air introduction passage 300 in the present embodiment is provided corresponding to the position where the support block 23 is provided, an air guide passage 400 extends inside the outer ring air mixing chamber into the support block 23, an inlet of the air guide passage 400 is provided on the base 1 and communicates with the secondary air introduction passage 300, and an outlet of the air guide passage 400 is provided on the support block 23 and communicates with the gap 24. In order to achieve a better air guiding effect, the gaps 24 on the supporting block 23 facing the two sides of the supporting block 23 are all provided with outlets of the air guiding channels 400. Thus, a part of the air entering from the secondary air introduction passage 300 is diverted to the air guide passage 400, and the air output from the outlet of the air guide passage 400 flows to the inner side of the outer ring flame through the gap 24 between the top plate 22 and the fire cover base body 21, so as to supply secondary air to the inner side of the outer ring flame for full combustion. Meanwhile, air entering the gap 24 between the top plate 22 and the fire cover base body 21 forms an air layer in the gap 24, so that the downward transmission of heat on the top plate 22 can be effectively reduced by the air layer, and the heating efficiency of a pot above the burner is improved.
The outer ring fire cover 2 and the inner ring fire cover 4 in the burner of the gas stove can effectively prevent the fire holes from being blocked, and have the functions of guiding and containing liquid, and the cleaning difficulty of overflowing liquid is reduced. Meanwhile, a space channel formed between the external liquid storage tank 3 and the internal liquid storage tank 5 plays a role in directional flow guide of secondary air, so that the external secondary air is directly supplied to the internal fire holes 40 after coming in, and full combustion is facilitated. The top wall of the outer ring fire cover 2 is obliquely arranged, so that overflow can flow inwards to the outer liquid storage tank 3 as much as possible, and smoke generated by the inner ring has a directional flow guiding effect, so that the smoke can be fully and effectively contacted with the bottom of the pot, and the heat efficiency is improved. In order to further prevent overflowing liquid from flowing outwards behind the top of the outer ring fire cover 2 to block the fire hole, a gap 24 is arranged on the top of the outer ring fire cover 2, so that overflowing liquid can flow into the outer liquid storage tank 3 after flowing from the top of the outer ring fire cover 2 to the gap 24. And the air guide channel 400 for supplying secondary air upwards is also designed at the secondary air guide channel 300, so that air is conveniently supplied to the inner side of the flame of the outer ring fire hole from the gap to be beneficial to full combustion, and meanwhile, an air layer can be formed in the gap 24 to play a heat insulation role, so that the heat transfer of the top plate 22 of the outer ring fire cover 2 to the lower part can be reduced, and the heat efficiency is further improved.
