Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of stove burners, and in particular to pressure equalization gas distribution plates. Background Technology
[0002] The burner is an important component of a stove. Existing stove burners include a gas distribution plate and a flame cap covering the gas distribution plate. The gas distribution plate has a central gas channel and an outer ring gas channel. The central gas channel extends vertically and connects to the air intake pipe. The outer ring gas channel is located outside the central gas channel and connects to the central gas channel through a connecting port. Gas enters the outer ring gas channel through the connecting port. The gas pressure is higher near the connecting port and lower further away from the connecting port in the outer ring gas channel. Due to the uneven gas pressure in the outer ring gas channel, the flame intensity of the outer ring of the stove burner is uneven, affecting the cooking effect. Utility Model Content
[0003] The purpose of this invention is to provide a pressure equalization gas distribution plate to solve the problem of uneven gas pressure in the outer ring gas channel of existing stove burners, which leads to uneven flame intensity in the outer ring of the stove burner and affects the cooking effect.
[0004] This utility model is achieved through the following technical solution:
[0005] The pressure equalizing distribution plate has an inner air passage and an outer air passage. The inner air passage extends vertically, and the outer air passage is arranged around the inner air passage. The outer air passage is connected to the inner air passage through a connecting port. A baffle is provided inside the outer air passage. The baffle extends outward from the upper side of the connecting port and is spaced apart from the lower wall of the outer air passage to form a pressurized space. The baffle has air passage holes that extend vertically.
[0006] Furthermore, the baffle extends outward from the upper edge of the communication port, and the baffle and the upper edge of the communication port are of equal length in the circumferential direction of the external air passage.
[0007] Furthermore, there are several air passages, which are spaced apart in the circumferential direction of the external air passage.
[0008] Furthermore, there are several connecting ports and several baffles, and they correspond one-to-one. The several connecting ports are spaced apart in the circumferential direction of the external air passage.
[0009] Furthermore, the inner wall of the external airway is formed with a slope, the slope is located below the baffle, and the slope extends obliquely from bottom to top in a direction away from the baffle.
[0010] Furthermore, the inclined surface is at least partially opposite the baffle.
[0011] Furthermore, the inner wall of the external airway is formed with a plurality of inclined surfaces, and the plurality of inclined surfaces correspond one-to-one with the plurality of baffles. The inclined surface group is composed of two inclined surfaces that are arranged opposite to each other in the length direction of the corresponding baffles, and the inclined surfaces extend obliquely from bottom to top in a direction away from the baffles.
[0012] Furthermore, it also has a connecting airway that connects the inner airway and the outer airway, the connecting opening being formed at one end of the connecting airway that connects to the outer airway, and the connecting airway extending obliquely upward toward the outer airway.
[0013] Furthermore, it includes an inner plate and an outer plate, the inner plate and the outer plate together forming the inner air passage and the outer air passage, and the inner plate and the outer plate are detachably fixedly connected.
[0014] Furthermore, the baffle is integrally formed with the inner disc.
[0015] The advantage of this technical solution is that by configuring a baffle in the external air passage, the baffle extends outward from the upper side of the connecting port and is spaced apart from the lower wall of the external air passage to form a pressurized space. After the gas flows into the pressurized space from the connecting port, part of it flows into the external air passage away from the connecting port in front of / back of the baffle, and part of it flows into the outlet space through the air hole. The baffle has a depressurization effect on the gas in the outlet space (the obstruction of the baffle makes the gas pressure entering the outlet space lower than the gas pressure near the connecting port when the baffle is not set). The baffle has a pressurization effect on the gas in the external air passage away from the connecting port (the gas pressure flowing into the external air passage away from the connecting port after being pressurized by the baffle is greater than the gas pressure flowing into the external air passage away from the connecting port when the baffle is not set). Thus, the gas pressure in the external air passage away from the connecting port tends to be consistent with the gas pressure in the outlet space, achieving pressure equalization gas output.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example: Figure 1-5 As shown, the equalizing gas distribution plate has an inner gas channel 1 and an outer gas channel 2. The inner gas channel 1 extends vertically, and the outer gas channel 2 is arranged around the inner gas channel 1. The outer gas channel 2 is connected to the inner gas channel 1 through a connecting port 3. A baffle 4 is provided inside the outer gas channel 2, extending outward from the upper side of the connecting port 3. The baffle 4 and the lower wall of the outer gas channel 2 are spaced apart to form a pressurized space 11. The baffle 4 has air passage holes 5 extending vertically to allow gas to pass through. This equalizing gas distribution plate is used in conjunction with a burner cap. The burner cap is placed on the upper end of the equalizing gas distribution plate and has an air outlet hole. The baffle 4 and the burner cap are spaced apart to form an air outlet space. Gas exits through the air outlet hole in the air outlet space, and the air outlet space is connected to the pressurized space 11 through the air outlet hole 5. For ease of description, the two opposite ends of the baffle 4 on the circumference of the outer gas channel 2 are defined as the front end and the rear end. This embodiment provides a pressure equalization gas distribution plate to solve the problem of uneven gas pressure in the outer ring gas duct of existing stove burners, which leads to uneven flame intensity in the outer ring of the burner and affects cooking performance. This is mainly achieved by configuring a baffle 4 inside the outer gas duct 2. The baffle 4 extends outward from the upper side of the connecting opening 3 and is spaced apart from the lower wall of the outer gas duct 2 to form a pressurized space 11. After the gas flows into the pressurized space 11 from the connecting opening 3, part of it flows towards the front / rear end of the baffle 4 into the outer gas duct 2 away from the connecting opening 3, and part of it flows into the outlet space through the air hole 5. The baffle 4 controls the outlet space... For the gas inside the space, the baffle 4 acts as a depressurizer (the baffle 4 makes the gas pressure entering the outlet space lower than the gas pressure near the connection port 3 when the baffle 4 is not installed). The baffle 4 acts as a pressurizer for the gas in the outer air passage 2 that is far from the connection port 3 (the gas pressure flowing into the outer air passage 2 that is far from the connection port 3 after being pressurized by the baffle 4 is greater than the gas pressure flowing into the outer air passage 2 that is far from the connection port 3 when the baffle 4 is not installed). This makes the gas pressure in the outer air passage 2 that is far from the connection port 3 more consistent with the gas pressure in the outlet space, thus achieving equal pressure outlet.
[0025] In this embodiment of the invention, the baffle 4 extends outward from the upper edge of the connecting port 3, and the baffle 4 and the upper edge of the connecting port 3 are of equal length in the circumferential direction of the external air passage 2. By configuring the baffle 4 to extend outward from the upper edge of the connecting port 3 and to be of equal length to the upper edge of the connecting port 3, the pressurized space 11 has a good interception effect and a pressurization effect.
[0026] In this embodiment of the invention, there are several air passages 5, which are spaced apart circumferentially in the outer air passage 2. By arranging several air passages 5 at intervals circumferentially in the outer air passage 2, the gas in the pressurized space 11 enters the outlet space evenly, thereby stabilizing the air pressure in the outlet space.
[0027] In this embodiment of the invention, there are multiple connecting ports 3 and baffles 4, each corresponding to one another. The multiple connecting ports 3 are spaced apart in the circumferential direction of the external air passage 2. By configuring multiple connecting ports 3 and baffles 4 in a one-to-one correspondence, the air pressure in the external air passage 2 tends to be uniform.
[0028] In this embodiment of the invention, an inclined surface 6 is formed on the inner wall of the external air passage 2. The inclined surface 6 is located below the baffle 4 and extends obliquely upwards away from the baffle 4. By configuring the inclined surface 6 on the inner wall of the external air passage 2, and having the inclined surface 6 located below the baffle 4 and extending obliquely upwards away from the baffle 4, the gas flowing away from the connecting opening 3 is pressurized a second time on the inclined surface 6, making the air pressure in the external air passage 2 away from the connecting opening 3 more consistent with the air pressure in the outlet space, resulting in uniform air output.
[0029] In this embodiment of the invention, the inclined surface 6 is at least partially aligned with the baffle 4. By configuring the inclined surface 6 to be at least partially aligned with the baffle 4, the gas flowing away from the connecting opening 3 is pressurized a second time on the inclined surface 6, making the gas pressure at the location of the external air passage 2 away from the connecting opening 3 more consistent with the gas pressure in the outlet space, resulting in uniform gas output.
[0030] In this embodiment of the invention, a plurality of inclined surface groups 7 are formed on the inner wall of the external air passage 2. Each of the inclined surface groups 7 corresponds one-to-one with a plurality of baffles 4. Each inclined surface group 7 consists of two inclined surfaces 6 arranged opposite each other along the length of the corresponding baffle 4. The inclined surfaces 6 extend obliquely upwards from the bottom towards the direction away from the baffle 4. This arrangement, by configuring a plurality of inclined surface groups 7 on the inner wall of the external air passage 2, with each group consisting of two inclined surfaces 6 arranged opposite each other along the length of the corresponding baffle 4, causes the gas flowing away from the connecting opening 3 to be pressurized a second time on the inclined surfaces 6, making the air pressure in the external air passage 2 away from the connecting opening 3 more consistent with the air pressure in the outlet space.
[0031] In this embodiment of the invention, the pressure equalizing and distributing plate further includes a connecting airway 8 that connects the inner airway 1 and the outer airway 2. A connecting port 3 is formed at the end of the connecting airway 8 that connects to the outer airway 2. The connecting airway 8 extends obliquely upwards towards the outer airway 2. This arrangement, by configuring the connecting airway 8 to extend obliquely upwards towards the outer airway 2, facilitates the flow of gas from the inner airway 1 into the outer airway 2.
[0032] In this embodiment of the invention, the pressure equalizing and distributing plate includes an inner plate 9 and an outer plate 10. The inner plate 9 and the outer plate 10 together form an inner air passage 1, an outer air passage 2, and a connecting air passage 8. A baffle 4 is integrally formed with the inner plate 9, and the inner plate 9 and the outer plate 10 are detachably and fixedly connected. This configuration, by setting the pressure equalizing and distributing plate as an inner plate 9 and an outer plate 10, with the inner plate 9 and the outer plate 10 together forming the inner air passage 1, the outer air passage 2, and the connecting air passage 8, and with the detachable and fixed connection, makes the pressure equalizing and distributing plate structurally reasonable and compact, and easy to assemble and disassemble.
[0033] In this embodiment of the invention, the baffle 4 and the inner disk 9 are integrally formed. By configuring the baffle 4 to be integrally formed with the inner disk 9, the structure of the pressure equalization and distribution disk is made reasonable and compact, simplifying the production steps.
