Description
Technical Field
[0001] This utility model relates to the field of stove technology, and in particular to a top-intake burner and stove. Background Technology
[0002] Currently, the nozzles of top-intake burners on the market are usually located directly below the mixing chamber. There is a gap between the mixing chamber and the nozzle, and some overflow liquid flows down the bottom of the mixing chamber to the nozzle, causing nozzle blockage and affecting the combustion effect of the top-intake burner. Existing technology adds ribs to the nozzle to block the overflow, but this can only block part of the overflow liquid, and the effect of blocking the overflow liquid is poor. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the defect of easy clogging of the nozzle of the existing top-intake burner, and to provide a top-intake burner and stove.
[0004] The present invention solves the above-mentioned technical problems through the following technical solution:
[0005] This utility model provides an upper air intake burner, which includes a nozzle, a nozzle column, and a mixing chamber. The nozzle and the nozzle column are located below the mixing chamber. The nozzle includes a fixing part and an injection part. The fixing part is connected to the nozzle column, and the injection part is exposed outside the nozzle column. The injection direction of the nozzle is to horizontally spray towards the radially inner side of the upper air intake burner. The upper air intake burner also includes an anti-clogging structure, which includes an upper plate. The upper plate is located above the injection part, and the projection of the injection part toward the upper plate in the vertical direction is located on the upper plate.
[0006] In this design, the top-inlet burner includes a nozzle, a nozzle column, a mixing chamber, and an anti-clogging structure. The nozzle and nozzle column are located below the mixing chamber. The nozzle includes a fixed part and an injection part. The fixed part is connected to the nozzle column, and the injection part is exposed outside the nozzle column. The nozzle's injection direction is a horizontal injection to the radial inner side of the top-inlet burner. The anti-clogging structure has an upper plate. By placing the upper plate above the injection part and ensuring that the vertical projection of the injection part onto the upper plate is entirely on the upper plate, the upper plate completely covers the injection part of the nozzle. This allows the overflow above the injection part to be blocked by the upper plate, preventing it from falling directly onto the injection part. The overflow can be guided to the outside of the nozzle by the upper plate, preventing the overflow from flowing towards the nozzle and preventing the nozzle from being clogged by the overflow.
[0007] Preferably, the upper plate and the spray section have a gap in the vertical direction.
[0008] In this design, the gap between the upper plate and the spray section can increase heat dissipation, reduce splashing around the nozzle caused by high temperature, and further prevent overflow from clogging the nozzle.
[0009] Preferably, the anti-clogging structure further includes side plates, which are formed by downward extension of both sides of the upper plate. The side plates are located on both sides of the spray section and are parallel to the spray direction of the nozzle.
[0010] In this design, the side plates on both sides of the spray section can block the overflow from splashing on both sides, prevent the overflow from flowing to the nozzle, and prevent the nozzle from being blocked by the overflow. The side plates are parallel to the spray direction of the nozzle, thereby preventing the side plates from blocking the sprayed gas.
[0011] Preferably, the projection of the spray section toward the side plate in the horizontal direction is all located on the side plate.
[0012] In this solution, by ensuring that the projection of the spray section towards the side plate in the horizontal direction is located on the side plate, the side plate can fully block both sides of the spray section, thereby effectively blocking the overflow from both sides of the nozzle and further improving the overflow blocking effect.
[0013] Preferably, the side plate and the spray section have a gap in the horizontal direction.
[0014] In this design, the gap between the side plate and the spray section can increase heat dissipation, reduce splashing around the nozzle caused by high temperature, and further prevent overflow from clogging the nozzle.
[0015] Preferably, the lower end of the anti-blocking structure is open.
[0016] In this design, by opening the lower end of the anti-blocking structure, primary air can flow from the lower opening of the anti-blocking structure to the injection section inside the anti-blocking structure. This allows the primary air to mix more fully with the combustion gas injected by the injection section, resulting in more sufficient air replenishment and improved combustion efficiency of the burner.
[0017] Preferably, the anti-clogging structure is integrally formed with the nozzle column.
[0018] In this solution, the anti-clogging structure is integrally molded with the nozzle column, making the burner easier to manufacture.
[0019] Preferably, the upper end of the anti-clogging structure or the nozzle column is provided with a positioning element, and the lower end of the mixing chamber is provided with a positioning part that matches the positioning element.
[0020] In this solution, the positioning component at the upper end of the anti-clogging structure or nozzle column cooperates with the positioning part at the lower end of the mixing chamber, thereby positioning the nozzle and the mixing chamber more accurately. The positioning component and positioning part make it easier to position and assemble the burner.
[0021] Preferably, the projection of the injection section toward the mixing chamber in the vertical direction is all located on the mixing chamber.
[0022] In this solution, by placing the projection of the spray nozzle toward the mixing chamber in the vertical direction on the mixing chamber, the mixing chamber can fully block the spray nozzle, thereby preventing a portion of the overflow from flowing toward the spray nozzle and further enhancing the overflow blocking effect.
[0023] This utility model also provides a stove, which includes a stove panel and the upper air intake burner, with the nozzle and the nozzle column disposed above the stove panel.
[0024] In this design, the stove has the same effect as the aforementioned top-intake burner.
[0025] The positive and progressive effects of this utility model are as follows:
[0026] This utility model provides an upward-intake burner, which includes a nozzle, a nozzle column, a mixing chamber, and an anti-clogging structure. The nozzle and nozzle column are located below the mixing chamber. The nozzle includes a fixing part and a spraying part. The fixing part is connected to the nozzle column, and the spraying part is exposed outside the nozzle column. The spraying direction of the nozzle is a horizontal spraying towards the radial inner side of the upward-intake burner. The anti-clogging structure is provided with an upper plate. By placing the upper plate above the spraying part and ensuring that the projection of the spraying part towards the upper plate in the vertical direction is all located on the upper plate, the upper plate can fully block the overflow from above the nozzle. The overflow can be guided to the outside of the nozzle by the upper plate, preventing the overflow from flowing to the nozzle and preventing the nozzle from being blocked by the overflow.

[0044] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the following embodiments.
[0045] like Figures 1-3 As shown, this embodiment provides a cooktop, which includes a cooktop panel and an upper air intake burner 100. The upper air intake burner 100 includes a nozzle 200, a nozzle column 300, and a mixing chamber 400. The nozzle 200 and the nozzle column 300 are located below the mixing chamber 400 and above the cooktop panel. The nozzle column 300 has a gas passage 310 inside, which connects to the nozzle 200 and is used to supply gas to the nozzle 200.
[0046] The nozzle 200 includes a fixing part 210 and an injection part 220. The fixing part 210 is connected to the nozzle post 300, and the injection part 220 is exposed outside the nozzle post 300. The injection part 220 is used to inject the gas obtained from the gas passage 310 into the ejector tube 700, and then flow into the mixing chamber 400 through the ejector tube 700. In this embodiment, the injection direction of the nozzle 200 is a horizontal injection towards the radial inner side of the upward air intake burner 100. The upward air intake burner 100 also includes an anti-clogging structure 500, which includes an upper plate 510. The upper plate 510 is located above the injection part 220, and the projection of the injection part 220 toward the upper plate 510 in the vertical direction is all located on the upper plate 510, i.e. Figure 2 As shown, the spray section 220 completely covers the nozzle 200 above the nozzle 200, so that the upper plate 510 can fully block the overflow from the nozzle 200. The overflow can be guided to the outside of the nozzle 200 by the upper plate 510 to prevent the overflow from flowing to the nozzle 200 and to prevent the nozzle 200 from being blocked by the overflow.
[0047] As shown in Figure 2, the upper plate 510 and the spray section 220 have a gap in the vertical direction. The gap between the upper plate 510 and the spray section 220 can increase heat dissipation, reduce splashing around the nozzle 200 caused by high temperature, and further prevent overflow from clogging the nozzle 200.
[0048] The anti-clogging structure 500 also includes side plates 520, which extend downward from both sides of the upper plate 510 to form side plates 520. The side plates 520 are located on both sides of the injection section 220 and are parallel to the injection direction of the nozzle 200. The side plates 520 on both sides of the injection section 220 can block the overflow liquid splashed from both sides, preventing the overflow liquid from flowing to the nozzle 200 and preventing the nozzle 200 from being blocked by the overflow liquid. The side plates 520 are parallel to the injection direction of the nozzle 200, thereby preventing the side plates 520 from blocking the injected gas.
[0049] In this embodiment, the side plate 520 is parallel to the injection direction of the nozzle 200. In other embodiments, the side plate 520 may also be inclined to the outside of the nozzle 200, or other extension directions of the side plate 520 may be selected as appropriate by those skilled in the art. The position of the side plate 520 should, as far as possible, not obstruct the gas ejected from the injection section 220.
[0050] In this embodiment, the side plate 520 is a plane. In other embodiments, the side plate 520 may also be a curved surface, or other specific shapes of the side plate 520 may be selected as deemed suitable by those skilled in the art.
[0051] The projection of the spray section 220 toward the side plate 520 in the horizontal direction is all located on the side plate 520. That is to say, the side plate 520 completely covers the side of the spray section 220, so that the side plate 520 can fully block both sides of the spray section 220 and can fully block the overflow from both sides of the nozzle 200, further improving the overflow blocking effect.
[0052] The side plate 520 and the spray section 220 have a gap in the horizontal direction. The gap between the side plate 520 and the spray section 220 can increase heat dissipation, reduce splashing around the nozzle 200 caused by high temperature, and further prevent overflow from clogging the nozzle 200.
[0053] In this embodiment, the lower end of the anti-clogging structure 500 is open, thereby better drawing in the primary air below the nozzle 200, making the air supply more sufficient, and improving the combustion effect of the burner. In other embodiments, the lower end of the anti-clogging structure 500 may also be closed.
[0054] In this embodiment, the anti-clogging structure 500 and the nozzle column 300 are integrally formed, which facilitates the production and assembly of the burner. In other embodiments, the anti-clogging structure 500 and the nozzle column 300 may also be produced separately and then assembled.
[0055] The upper end of the anti-clogging structure 500 or the nozzle column 300 is provided with a positioning element 610, and the lower end of the mixing chamber 400 is provided with a positioning part 620 that matches the positioning element 610. The positioning element 610 at the upper end of the anti-clogging structure 500 or the nozzle column 300 cooperates with the positioning part 620 at the lower end of the mixing chamber 400, thereby positioning the nozzle 200 and the mixing chamber 400 more accurately. The setting of the positioning element 610 and the positioning part 620 facilitates the positioning and assembly of the burner.
[0056] In this embodiment, the positioning member 610 is a protruding columnar structure, and the matching positioning part 620 is a hole-like structure located at the lower end of the mixing chamber 400. The columnar structure is inserted into the hole-like structure to position the mixing chamber 400 and the anti-blocking structure 500. In other embodiments, the positioning member 610 may also be a hole-like structure, and the positioning part 620 may be a columnar structure. Alternatively, other specific structures of the positioning member 610 and the positioning part 620 that are deemed suitable by those skilled in the art may be selected.
[0057] In this embodiment, the vertical projection of the spray section 220 toward the mixing chamber 400 is all located on the mixing chamber 400, so that the mixing chamber 400 can fully block the spray section 220. That is, the spray section 220 is completely located below the mixing chamber 400, and the mixing chamber 400 can block a portion of the overflow from flowing toward the spray section 220, further improving the overflow blocking effect. In other embodiments, the vertical projection of the spray section 220 toward the mixing chamber 400 can also be located on the mixing chamber 400, which can also make the mixing chamber 400 effectively block a portion of the overflow from flowing toward the spray section 220.
