Description

Technical Field

[0001] The utility model relates to the technical field of gas stoves, in particular to a flame stabilizing structure of a fire cover, an inner ring fire cover and a burner. Background Art

[0002] Stir-frying and frying are common cooking methods used by users. Burners work in heavy oil environments for a long time, and it is inevitable that oil stains will adhere to the surface of the burners, especially in Sichuan and Chongqing. Frequent stir-frying and frying will cause oil stains to adhere to the inner and outer ring fire covers. When the oil stains are deposited in the flame stabilizing groove of the inner ring fire cover for a long time, the oil stains will block the flame stabilizing groove, resulting in ignition failure, abnormal flame protection, etc. According to market feedback, the main reason for abnormal ignition and flame protection is the flame separation caused by the blockage of the flame stabilizing groove and the ignition hole. Therefore, there is an urgent need for a structure that can solve the ignition and flame protection failure caused by oil stain blockage. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the defect in the prior art that the fire hole is easily blocked by oil dirt, resulting in failure of ignition and fire protection, and to provide a flame stabilizing structure of a fire cover, an inner ring fire cover and a burner.

[0004] The utility model solves the above technical problems through the following technical solutions:

[0005] A flame stabilizing structure of a fire cover, wherein the flame stabilizing structure of the fire cover is arranged on an inner ring fire cover, and the flame stabilizing structure of the fire cover comprises:

[0006] A drain hole, which is connected to the flame stabilizing groove of the inner ring fire cover. The drain hole is eccentrically arranged on the inner ring fire cover and close to the brim of the inner ring fire cover. The drain hole is perpendicular to the flame stabilizing groove along the length direction. Both ends of the drain hole pass through the side walls of the inner ring fire cover, and the gas channel of the inner ring fire cover is connected to the drain hole.

[0007] In this solution, a drain hole connected to the flame stabilizing groove is provided to discharge the oil deposited in the flame stabilizing groove through the drain hole to avoid the oil from clogging the flame stabilizing groove, and the gas can also enter the flame stabilizing groove through the drain hole, thereby realizing the continuous flame-keeping function of the flame stabilizing groove. At the same time, the drain hole arranged near the brim can not only discharge the oil in the flame stabilizing groove, but also the ignition hole of the inner ring fire cover is located below the brim, which simultaneously reduces the oil deposited in the ignition hole, so as to ensure the ignition success rate of the ignition hole and the service life of the fire cover.

[0008] Preferably, a plurality of flame stabilizing air outlet holes are provided in the flame stabilizing groove, one end of the flame stabilizing air outlet hole is connected to the flame stabilizing groove, and the other end of the flame stabilizing air outlet hole is connected to the sewage discharge hole.

[0009] In this solution, a plurality of flame stabilizing gas outlet holes are provided to ensure the amount of fuel gas entering the flame stabilizing tank, while avoiding the situation where there is no fuel gas supply in the flame stabilizing tank when some of the flame stabilizing gas outlet holes are blocked.

[0010] Preferably, the sewage discharge hole, the flame stabilizing groove and the flame stabilizing air outlet hole are all arranged in a horizontal direction.

[0011] In this solution, the drain holes arranged in the horizontal direction can prevent the oil from being deposited on one side of the side wall of the inner ring fire cover when draining the oil, so as to evenly drain the oil and avoid the situation where the oil is deposited on the same side and the fire holes are blocked, making it impossible to evenly heat the cookware.

[0012] Preferably, the thickness of the side wall of the inner fire ring cover on the side where the drain hole is arranged is greater than the thickness of the side wall of the inner fire ring cover away from the drain hole.

[0013] In this solution, through the above arrangement, the drain hole can be set in the side wall of the inner ring fire cover, avoiding the drain hole directly penetrating the gas channel of the inner ring fire cover and causing oil and dirt to enter the gas channel.

[0014] Preferably, the drain hole is provided with an air inlet hole along the vertical direction, and the drain hole is connected with the gas channel through the air inlet hole.

[0015] In this solution, the air inlet holes arranged in the vertical direction can slow down the flow rate of the gas entering the drain hole, so as to accumulate the gas in the flame stabilizing groove and improve the fire-keeping performance.

[0016] Preferably, a plurality of air inlet holes are provided and are spaced apart along the extension direction of the sewage discharge hole.

[0017] In this solution, multiple air inlet holes ensure that the amount of fuel gas entering the flame stabilizing groove is sufficient, thereby avoiding poor flame-keeping performance caused by insufficient gas volume.

[0018] Preferably, the diameter of the drain hole is not less than 3 mm.

[0019] In this solution, the drain hole greater than or equal to 3 mm can effectively drain the oil and prevent the oil from being deposited in the drain hole.

[0021] In this solution, the inner ring fire cover includes the above-mentioned fire cover flame stabilizing structure, so that the service life of the inner ring fire cover is correspondingly improved, the fire protection performance and the ignition success rate are guaranteed, and the cookware can be evenly heated to avoid uneven heating of the cookware caused by blockage of the fire hole on one side.

[0022] Preferably, the inner ring fire cover is also provided with a flame stabilizing hole, and the flame stabilizing hole is arranged below the flame stabilizing groove.

[0023] In this solution, flame stabilizing holes and flame stabilizing grooves are provided to further improve the fire-keeping performance.

[0024] A burner comprises the inner ring fire cover as described above.

[0025] In this solution, the burner includes the above-mentioned inner ring fire cover, so that the service life of the burner is correspondingly improved, the fire protection performance and the ignition success rate are guaranteed, and the cookware can be evenly heated to avoid uneven heating of the cookware caused by blockage of the fire hole on one side.

[0026] The positive and progressive effect of the utility model is that the utility model sets a drainage hole connected to the flame stabilizing groove to discharge the oil deposited in the flame stabilizing groove through the drainage hole to avoid the oil from clogging the flame stabilizing groove, and the gas can also enter the flame stabilizing groove through the drainage hole, so as to achieve the continuous flame-keeping function of the flame stabilizing groove. At the same time, the drainage hole set near the brim can not only discharge the oil in the flame stabilizing groove, but also the ignition hole of the inner ring fire cover is located below the brim, and the oil deposited in the ignition hole is simultaneously reduced to ensure the ignition success rate of the ignition hole and the service life of the fire cover.

[0043] Air Inlet 2 DETAILED DESCRIPTION

[0044] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0045] This embodiment provides a flame stabilizing structure of a fire cover, the specific structure is as follows Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the flame stabilizing structure of the fire cover is arranged on the inner ring fire cover 10, and the flame stabilizing structure of the fire cover includes:

[0046] The drain hole 1 is connected with the flame stabilizing groove 11 of the inner ring fire cover 10. The drain hole 1 is eccentrically arranged on the inner ring fire cover 10 and is close to the brim 12 of the inner ring fire cover 10. The drain hole 1 is perpendicular to the flame stabilizing groove 11 along the length direction. Both ends of the drain hole 1 pass through the side walls of the inner ring fire cover 10. The gas channel 13 of the inner ring fire cover 10 is connected with the drain hole 1.

[0047] Specifically, a brim 12 is provided on the top of the inner ring fire cover 10, and a flame stabilizing groove 11 and a plurality of fire holes are provided on the side wall of the inner ring fire cover 10. The flame stabilizing groove 11 and the plurality of fire holes are shielded from overflow from the cookware by the brim 12 to prevent the overflow from clogging the flame stabilizing groove 11 and the fire holes. The flame stabilizing groove 11 and the fire holes are connected with the gas channel 13 to obtain gas. This is the prior art and will not be elaborated on here.

[0048] The drain hole 1 is arranged on the side wall of the inner ring fire cover 10, and is located in the side wall of the inner ring fire cover 10 below the brim 12. The drain hole 1 is a circular hole, and of course it can also be a hole of other shapes, which will not be described in detail here. The circular hole is opened from the side wall of the inner ring fire cover 10 close to the brim 12. It should be noted that the circular hole is always located in the side wall instead of punching the circular hole into the gas channel 13. The drain hole 1 is connected to the flame stabilizing groove 11, and both ends of the drain hole 1 pass through the side wall of the inner ring fire cover 10. From the appearance point of view, the length direction of the drain hole 1 is perpendicular to the setting direction of the flame stabilizing groove 11. Compared with the method in which the drain hole 1 and the flame stabilizing groove 11 are set in the same direction, it can prevent oil from entering the drain hole 1 and then the distance when it is discharged is shorter, thereby reducing the deposition of oil in the drain hole 1.

[0049] When the oil is diverted, the oil first enters the drain hole 1 from the flame stabilizing groove 11, and then is guided out of the inner ring fire cover 10 through the two ends of the drain hole 1, so that the oil deposited in the flame stabilizing groove is discharged through the drain hole 1, thereby achieving the diversion of the oil and avoiding the oil from clogging the flame stabilizing groove 11. In addition, the above-mentioned diversion is continuous, that is to say, the oil can be continuously diverted each time it is used or used for a long time. The drain hole 1 is connected with the gas channel 13, and the gas can also enter the flame stabilizing groove 11 through the drain hole 1 when the fire cover is burning normally, thereby ensuring that the air intake of the flame stabilizing groove 11 is not affected by the oil deposition, thereby achieving the continuous fire preservation function of the flame stabilizing groove 11.

[0050] At the same time, the drain hole 1 arranged near the brim 12 can not only discharge the oil stains in the flame stabilizing groove 11, but the ignition hole of the inner ring fire cover 10 is also located below the brim 12. Since the ignition hole is close to the flame stabilizing groove 11, when the drain hole 1 guides the oil stains in the flame stabilizing groove 11, the oil stains in the area where the flame stabilizing groove 11 is located are also reduced accordingly, thereby simultaneously reducing the oil stains deposited in the ignition hole, so as to ensure the ignition success rate of the ignition hole and the service life of the fire cover.

[0051] In this embodiment, if Figure 5 and Figure 6 As shown, a plurality of flame stabilizing gas outlet holes 111 are provided in the flame stabilizing tank 11 , one end of the flame stabilizing gas outlet hole 111 is connected to the flame stabilizing tank 11 , and the other end of the flame stabilizing gas outlet hole 111 is connected to the drain hole 1 .

[0052] Specifically, the flame stabilizing gas outlet 111 is located between the flame stabilizing groove 11 and the drain hole 1, and the drain hole 1 supplies gas to the flame stabilizing groove 11 through the flame stabilizing gas outlet 111 to ensure the amount of gas entering the flame stabilizing groove 11, while avoiding the situation where there is no gas supply in the flame stabilizing groove 11 when some of the flame stabilizing gas outlets 111 are blocked. When the fire cover burns normally, the flame stabilizing groove 11 always keeps burning, and the gas can flow out from the end of the drain hole 1 after entering the drain hole 1, thereby removing the oil deposited in the drain hole 1.

[0053] In this embodiment, if Figure 3 and Figure 6 As shown, the sewage discharge hole 1, the flame stabilizing groove 11 and the flame stabilizing gas outlet hole 111 are all arranged in the horizontal direction.

[0054] Specifically, the drain hole 1 is opened in the horizontal direction to prevent the oil from being deposited on one side of the side wall of the inner ring fire cover 10 when the oil is removed, so as to evenly remove the oil and avoid the oil from being deposited on the same side, causing the fire hole to be blocked and the cookware to be unable to be evenly heated. In addition, the flame stabilizing groove 11 and the flame stabilizing air outlet 111 arranged in the horizontal direction reduce the gas flow rate when the flame stabilizing groove 11 burns, and the flame is more concentrated to avoid flame separation. Even if the oil enters the drain hole 1 from the flame stabilizing groove 11, compared with the inclined flame stabilizing air outlet 111, the horizontally arranged flame stabilizing air outlet 111 can prevent the oil from accelerating into the drain hole 1.

[0055] In this embodiment, the thickness of the side wall of the inner fire ring cover 10 on the side where the drain hole 1 is provided is greater than the thickness of the side wall of the inner fire ring cover 10 on the side away from the drain hole 1 .

[0056] Specifically, since the drain hole 1 is arranged in the side wall of the inner ring fire cover 10, in order to prevent the drain hole 1 from penetrating into the gas channel 13 when opening, the thickness of the side wall on the side where the drain hole 1 is arranged is thickened to ensure that the side wall of the drain hole 1 is a solid structure when opening, thereby ensuring that oil stains will not directly enter the gas channel 13 from the drain hole 1 and block the gas channel 13 when discharging sewage.

[0057] Furthermore, the thickened side walls of the inner ring fire cover 10 also provide sufficient space for setting the flame stabilizing groove 11 along the horizontal direction, thereby preventing the flame stabilizing groove 11 from directly penetrating into the gas channel 13 when grooving, thereby improving the structural reliability of the inner ring fire cover 10.

[0058] like Figure 7 As shown, in this embodiment, the drain hole 1 is provided with an air inlet hole 2 along the vertical direction, and the drain hole 1 is connected with the gas channel 13 through the air inlet hole 2.

[0059] Specifically, the air inlet 2 is arranged along the vertical direction, and the gas flow direction of the gas channel 13 is along the vertical direction. That is to say, after the gas enters the drain hole 1 from the air inlet 2, when it flows into the flame stabilizing outlet hole 111, the gas flows in the vertical direction, that is, the vertical direction is changed into horizontal flow, thereby slowing down the gas flow rate entering the drain hole 1. It can be understood that the vertical flow has a lower flow rate than the inclined air inlet 2, so that the gas is accumulated in the flame stabilizing groove 11 to improve the fire protection performance.

[0060] In this embodiment, a plurality of air inlet holes 2 are provided and are spaced apart along the extension direction of the sewage discharge hole 1 .

[0061] Specifically, a plurality of air inlet holes 2 are arranged at intervals along the length direction of the sewage discharge hole 1. The plurality of air inlet holes 2 ensure that the amount of fuel gas entering the sewage discharge hole 1 and the flame stabilizing groove 11 is sufficient, thereby avoiding poor flame preservation performance caused by insufficient gas volume.

[0062] In addition, the multiple air inlet holes 2 can also avoid the defect that a single air inlet hole 2 cannot provide gas when it is blocked.

[0063] In this embodiment, the diameter of the drain hole 1 is not less than 3 mm.

[0064] Specifically, the size of the oil stain is smaller than the diameter of the drain hole 1 , usually less than 3 mm, and the diameter of the drain hole 1 is set to be greater than or equal to 3 mm, so that the drain hole 1 can effectively drain the oil stain and avoid the oil stain from being deposited in the drain hole 1 .

[0065] This embodiment also provides an inner ring fire cover 10, and the inner ring fire cover 10 includes the flame stabilizing structure of the fire cover mentioned above.

[0066] Specifically, the inner ring fire cover 10 is a cylindrical structure with a gas passage 13 inside. A plurality of fire holes are opened on the side wall of the inner ring fire cover 10. A brim 12 is set on the top of the inner ring fire cover 10 to block overflow. In addition, a drain hole 1 is set in the side wall of the inner ring fire cover 10 near the brim 12. The drain hole 1 is set in the horizontal direction and is connected with the flame stabilizing groove 11. The drain hole 1 runs through the side wall of the inner ring fire cover 10 and the length direction of the drain hole 1 is perpendicular to the groove direction of the flame stabilizing groove 11. After the oil enters the drain hole 1 through the flame stabilizing groove 11, the oil will not stay in the drain hole 1 for too long, and the oil will be directly diverted out of the drain hole 1, so as to reduce the oil deposition in the flame stabilizing groove 11, improve the service life of the inner ring fire cover 10, and improve the fire protection performance accordingly.

[0067] The ignition hole of the inner ring fire cover 10 is also arranged close to the brim 12, so that when the drain hole 1 removes the oil stains at the flame stabilizing groove 11, the concentration of oil stains near the ignition hole is reduced, and the probability of ignition hole blockage is correspondingly reduced, and the ignition success rate is guaranteed. In addition, the two ends of the drain hole 1 remove oil stains more evenly, avoiding the accumulation of oil stains at one end and blocking the fire hole, so that the fire hole at that place has no flame when burning, and the bottom of the pot is heated unevenly when heating the pot, so as to evenly heat the pot and improve the user experience.

[0068] In this embodiment, the inner ring fire cover 10 is further provided with flame stabilizing holes, which are arranged below the flame stabilizing grooves 11 .

[0069] Specifically, the flame stabilizing hole is a flame stabilizing hole in the prior art, and its setting direction can be set in an outward inclined direction along the gas flow direction of the gas channel 13, or can be set in a horizontal direction, or can be a setting method in which the horizontal direction and the inclined direction are connected. It can be selected according to the actual use environment. The flame stabilizing hole and the flame stabilizing groove 11 are both located below the brim 12 and jointly maintain the flame of the inner ring fire cover 10. Compared with the method of separately setting the flame stabilizing groove 11, the fire maintenance performance is further improved.

[0070] like Figure 1As shown, this embodiment further provides a burner 100 , and the burner 100 includes the inner ring fire cover 10 mentioned above.

[0071] Specifically, the burner includes an inner ring fire cover 10 and an outer ring fire cover 20. The inner ring fire cover 10 is provided with a drain hole 1 to prevent oil from being deposited on the inner ring fire cover 10 during cooking. Since the outer ring fire cover 20 is located on the outer peripheral side of the inner ring fire cover 10 and has a larger contact area with the external environment, the outer ring fire cover 20 is not easily blocked by oil. In the case where the inner ring fire cover 10 is not easily blocked by oil, the service life of the burner 100 is correspondingly improved, and the fire-keeping performance and ignition success rate are guaranteed. When used for a long time, the cookware can be evenly heated to avoid uneven heating of the cookware caused by the blockage of the fire hole on one side.

[0072] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
