All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of the technical solutions claimed by the present utility model.
[0027] Embodiment:
[0028] As Figures 1 to 4 shown, this embodiment provides an air conditioning device for a burner, including a burner head 1 and a burner base 2 provided on the burner head 1. It further includes a damper adjustment assembly 3. At least one ring of gas passages 4 is provided on the burner base 2. The cross-sectional area of the gas passage 4 gradually increases or gradually decreases from top to bottom. The damper adjustment assembly 3 is movably provided in the gas passage 4, and the damper adjustment assembly 3 is driven by an external force to move up and down in the vertical direction so that the damper adjustment assembly 3 adjusts the opening area of the gas passage 4.
[0029] In this embodiment, a burner base 2 is provided on the burner head 1. At least one ring of convex platforms is provided on the burner base 2. A hollow mixing cavity distributed along the ring surface is provided inside the convex platform to form a gas passage 4. The cross-sectional area of the gas passage 4 gradually increases or gradually decreases from top to bottom, so that the outer end wall of the gas passage 4 forms a slope structure. The damper adjustment assembly 3 is movably arranged in the gas passage 4. By an external force to drive the damper adjustment assembly 3 to move up and down in the vertical direction, the damper adjustment assembly 3 cooperates with the inner side wall of the gas passage 4 to adjust the opening area of the gas passage 4. Its structure is simple, which can effectively reduce the production cost of the product. At the same time, the opening adjustment of the damper can be visualized without disassembling the machine, thus further improving the uniformity of air mixing.
[0030] In this embodiment, the burner head 1 directly cancels the original damper plate and the bracket for installing the regulator around it, so that the blockage of the primary air intake passage can be reduced, thereby improving the mixing uniformity. At the same time, by directly transferring the damper adjustment assembly 3 to the upper part of the burner base 2, the opening condition of the gas passage 4 can be directly seen after directly removing the burner, thus further improving the user experience.
[0031] Furthermore, the damper adjustment assembly 3 includes a fixing plate 31, an adjusting rod 32 and a damper plate 33. The two ends of the fixing plate 31 are respectively connected to the two end walls of the gas passage 4. The upper end of the adjusting rod 32 is threadedly connected to the fixing plate 31. The damper plate 33 is movably arranged in the gas passage 4, and the damper plate 33 is connected to the lower end of the adjusting rod 32. The damper plate 33 adjusts the opening area of the gas passage 4 through the movement of the damper plate 33.
[0032] Preferably, a fixing hole is provided on the fixing plate 31, and an internal thread is provided on the fixing hole. The adjusting rod 32 is provided with an external thread at one end close to the fixing plate 31. The internal thread and the external thread are cooperatively connected to threadedly connect the adjusting rod 32 to the fixing plate 31.
[0033] Specifically, a groove 34 is recessed on the upper end wall of the adjusting rod 32.
[0034] Preferably, when the gas passage 4 is a pipe structure, the damper plate 33 is a circular plate structure.
[0035] Furthermore, when the gas passage 4 is an annular gas groove, the damper plate 33 is an annular structure.
[0036] In this embodiment, both ends of the fixing plate 31 are respectively connected to the two end walls of the gas passage 4, so that the fixing plate 31 is fixedly installed at the upper end position of the gas passage 4. Since there is a clearance fit between the air damper plate 33 and the gas passage 4, and the cross-sectional area of the gas passage 4 gradually increases or gradually decreases from top to bottom, the shape of the air damper plate 33 can be matched with the cross-sectional shape of the gas passage 4 in this way. The air damper plate 33 is fixedly installed on the adjusting rod 32. One end of the adjusting rod 32 away from the air damper plate 33 is threadedly connected to the fixing plate 31. Specifically, a fixing hole is provided on the fixing plate 31, and internal threads are provided on the inner side wall of the fixing hole. The adjusting rod 32 is provided with external threads at one end close to the fixing plate 31. After the end of the adjusting rod 32 close to the fixing plate 31 passes through the fixing hole, the adjusting rod 32 is threadedly connected to the fixing plate 31 through the cooperation of the internal threads and the external threads. Thus, by driving the adjusting rod 32 to move up and down in the vertical direction by an external force, the adjusting rod 32 drives the air damper plate 33 to move up or down synchronously through the action of the adjusting rod 32. In this way, the clearance between the circumferential side wall of the air damper plate 33 and the inner side wall of the gas passage 4 is adjusted through the lifting movement of the air damper plate 33, so as to adjust the opening area of the air damper plate 33 for the gas passage 4.
[0037] More preferably, a groove 34 is recessed on the upper end wall of the adjusting rod 32, which is beneficial for the user to operate the adjusting rod 32. After the user places other tools such as a screwdriver in the groove 34, the user can quickly drive the adjusting rod 32 to move up and down.
[0038] In this embodiment, when the cross-sectional area of the gas passage 4 gradually increases from top to bottom, when the air damper plate 33 is driven to move upward by an external force, the pressure becomes greater and greater, so that the amount of entrained air decreases. When the air damper plate 33 is driven to move downward by an external force, the pressure becomes smaller and smaller, so that the amount of entrained air increases. When the cross-sectional area of the gas passage 4 gradually decreases from top to bottom, when the air damper plate 33 is driven to move upward by an external force, the pressure becomes smaller and smaller, so that the amount of entrained air increases. When the air damper plate 33 is driven to move downward by an external force, the pressure becomes greater and greater, so that the amount of entrained air decreases.
[0039] Preferably, when the number of gas passages 4 is two rings, an outer ring gas passage 41 and an inner ring gas passage 42 with gradually decreasing radii are concentrically arranged on the burner base 2, and the air damper adjusting assemblies 3 are respectively arranged in the outer ring gas passage 41 and the inner ring gas passage 42.
[0040] Further, the outer end wall of the inner ring gas passage 42 is inclined from inside to outside and downward, so that the cross-sectional area of the inner ring gas passage 42 gradually increases from top to bottom, and the cross-sectional area of the outer ring gas passage 41 gradually decreases from top to bottom.
[0041] Specifically, it further includes an ejector pipe 5. One end of the ejector pipe 5 is connected to the external air supply, and the other end is connected to the gas channel 4.
[0042] In this embodiment, when the number of gas channels 4 is two rings, an outer ring gas channel 41 and an inner ring gas channel 42 with gradually decreasing radii are concentrically arranged on the burner base 2. The outer end wall of the inner ring gas channel 42 is inclined downward from the inside to the outside, so that the cross-sectional area of the inner ring gas channel 42 gradually increases from top to bottom, and the cross-sectional area of the outer ring gas channel 41 gradually decreases from top to bottom. At the same time, since the inner ring gas channel 42 is preferably a pipe structure, the air door plate 33 located in the inner ring gas channel 42 is a circular plate structure, and the outer ring gas channel 41 is preferably an annular gas groove, so that the air door plate 33 located in the inner and outer ring gas channels 42 is an annular structure. A damper adjustment assembly 3 is respectively arranged in the outer ring gas channel 41 and the inner ring gas channel 42 to adjust the opening area of the outer ring gas channel 41 and the inner ring gas channel 42 respectively.
[0043] In this embodiment, air enters the burner head 1 under the negative pressure generated by the high-speed gas at the front nozzle of the ejector pipe 5. Since there is no obstruction around the nozzle, the air will enter the burner base evenly from all around and mix with the gas for the first time. Since the air enters from all around, the mixing will be more uniform than when the air enters locally. At this time, the amount of air ejected into the burner base 2 is the largest, and the pressure and flow rate of the mixed gas are relatively large, which are likely to cause problems such as flame lift and failure to ignite during combustion. After adjusting the opening area of the inner ring gas channel 42 and the outer ring gas channel 41 respectively by using the damper adjustment assembly 3, the cross-sectional area of the upper part of the burner base 2 decreases, which will increase the pressure here, resulting in a decrease in the pressure difference formed between the nozzle and the external environment, and the amount of air ejected into the burner base 2 will decrease, so as to achieve the purpose of adjusting the primary air volume.
[0044] In this embodiment, the air adjustment device of the burner is preferably applied to an integrated stove, so as to overcome the defect that the air door piece is arranged inside the integrated stove and the user cannot intuitively understand the opening state of the air door through remote adjustment. Its design is reasonable, the operation is convenient, and the uniformity of air mixing can be effectively improved.
[0045] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the creative concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
