Description

Technical Field

[0001] This utility model specifically relates to a burner. Background Technology

[0002] The burner nozzles are located above the drip tray. During daily use, cooking may produce spills, which can accumulate in the drip tray and cause nozzle blockage. Alternatively, when cleaning, if the burner cap is removed and the nozzles are wiped with a cloth or other cleaning tools while wiping away spills, the spilled liquid on the cleaning tools may stick to the nozzles, causing them to become clogged. 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 located above the liquid tray in the prior art, and to provide a burner.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A burner includes a liquid collection tray, with a flame cap, an ejector tube, and a nozzle located above the liquid collection tray. The burner further includes:

[0006] A protective cover is provided with an extension along the height direction of the burner. The extension is located between the nozzle and the ejector tube, and the top of the extension has a shielding part. The shielding part is located above the nozzle and shields the nozzle. The protective cover is detachably connected to the liquid collection tray.

[0007] In this design, a protective cover is installed to enclose the nozzle, allowing the nozzle to be shielded from spillage, preventing direct clogging of the nozzle by spillage from the burner cap. Simultaneously, when the burner cap is removed and the liquid collection tray is cleaned, the extension covers the side of the nozzle, restricting the cleaning tool's range of motion if spillage adheres to it, thus isolating the cleaning tool and preventing it from getting too close to the nozzle and clogging it.

[0008] Preferably, a guide portion is provided at one end of the shielding portion away from the extension portion, and the guide portion extends obliquely downward from the plane where the shielding portion is located along the height direction of the burner.

[0009] In this solution, the above-mentioned arrangement guides the overflow to the collection tray when it drips onto the shielding part, thus preventing the overflow from accumulating on the shielding part.

[0010] Preferably, the flow guide includes a first flow guide plate and a second flow guide plate, the first flow guide plate and the second flow guide plate are connected in sequence, and the angle of inclination between the first flow guide plate and the plane where the shielding part is located is greater than the angle of inclination between the second flow guide plate and the plane where the shielding part is located.

[0011] In this solution, the above-mentioned settings accelerate the drainage of overflow by using a larger tilt angle of the first guide plate.

[0012] Preferably, the extension has a through hole corresponding to the area where the nozzle communicates with the ejector tube.

[0013] In this solution, the above settings ensure effective communication between the nozzle and the ejector tube.

[0014] Preferably, the diameter of the through hole is larger than the diameter of the ejector tube.

[0015] In this solution, the above settings are used to avoid the through-hole diameter being too small, which would affect the supply of gas from the nozzle to the ejector tube.

[0016] Preferably, the protective cover further includes a connecting portion, which is integrally bent with the extension portion and is parallel to the surface of the liquid collection tray. The connecting portion has a connecting hole, and the connecting portion is connected to the liquid collection tray by a bolt assembly passing through the connecting hole.

[0017] In this solution, the above-mentioned settings enable a detachable connection between the protective cover and the liquid collection tray.

[0018] Preferably, a slide is provided on the liquid collection tray corresponding to the connecting part, and a slider is slidably disposed in the slide, the slider being connected to the connecting part by the bolt assembly.

[0019] In this solution, the above-mentioned settings allow the protective cover to slide relative to the liquid collection tray.

[0020] Preferably, when the protective cover slides along the slide and approaches the nozzle, the air intake of the ejector tube is less than when the protective cover slides along the slide and moves away from the nozzle.

[0021] In this solution, the above-mentioned settings allow for adjustment of the primary air intake of the ejector tube while the protective cover is sliding, thus achieving the effect of a damper.

[0022] Preferably, the protective cover is provided with a clearance groove corresponding to the outer edge of the flame cap, and the clearance groove extends from the extension portion to the shielding portion.

[0023] In this solution, the above-mentioned settings are used to avoid interference with the flame cap when the protective cover is placed on the liquid tray, so that the positions of the flame cap and the nozzle do not need to be changed, which facilitates the upgrading of the existing structure.

[0024] Preferably, the shielding part is also provided with a clearance hole, which is provided corresponding to the top of the nozzle.

[0025] In this solution, the above-mentioned settings are used to avoid interference with the nozzle when the protective cover is placed on the liquid collection tray.

[0026] The positive and progressive effects of this invention are as follows: By setting a protective cover to enclose the nozzle, the nozzle can be shielded from overflow when facing liquid, preventing the overflow from the burner cap from directly clogging the nozzle. Simultaneously, when the burner cap is removed and the liquid tray is cleaned, the extension covers the side of the nozzle, restricting the range of motion of the cleaning tool if it has overflow on it, thus isolating the cleaning tool and preventing it from getting too close to the nozzle and clogging it.

[0049] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0050] This embodiment provides a burner, the specific structure of which is as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the burner includes a liquid collection tray 1, a burner cap 2, an injector tube 3, and a nozzle 4 located above the liquid collection tray 1. The burner also includes:

[0051] The protective cover 5 has an extension 51 along the height direction of the burner. The extension 51 is located between the nozzle 4 and the ejector tube 3, and the top of the extension 51 has a shielding part 52. The shielding part 52 is located above the nozzle 4 and shields the nozzle 4. The protective cover 5 is detachably connected to the liquid collection tray 1.

[0052] Specifically, the protective cover 5 includes an extension 51, which is a flat plate erected on the liquid tray 1. The extension 51 is located between the nozzle 4 and the ejector tube 3 to cover the side of the nozzle 4. This allows the extension 51 to block the side of the nozzle 4 when the flame cap 2 is removed and the liquid tray 1 is cleaned, so that the cleaning tool's range of motion is limited when the cleaning tool is covered with spilled liquid, i.e., the cleaning tool is isolated to prevent the cleaning tool from getting too close and touching the nozzle orifice and clogging the nozzle 4.

[0053] In addition, in this embodiment, the protective cover 5 also includes a shielding part 52. The shielding part 52 is a bent plate integrally formed with the extension part 51. The shielding part 52 is located above the extension part 51 to cover the top of the nozzle 4, so that the nozzle 4 can be shielded by the shielding part 52 when facing the overflow liquid, preventing the overflow liquid from the flame cap 2 from directly clogging the nozzle 4. This overcomes the problem that the nozzle 4 is easily clogged by overflow liquid or by cleaning tools with overflow liquid during cleaning.

[0054] Furthermore, such as Figure 3 and Figure 6 As shown, a guide portion 6 is provided at one end of the shielding portion 52 away from the extension portion 51. The guide portion 6 extends downward at an angle from the plane where the shielding portion 52 is located along the height direction of the burner.

[0055] Specifically, the guide section 6 is also made of sheet metal and is integrally formed with the shielding section 52. The guide section 6 is located at the edge of the shielding section 52 away from the extension section 51. The guide section 6 is inclined relative to the plane where the shielding section 52 is located, and along the height direction of the burner, the guide section 6 is inclined downward so that when the overflow drips onto the shielding section 52, the overflow can be guided to the liquid collection tray 1 through the inclined downward guide section 6, thus preventing the overflow from accumulating on the shielding section 52.

[0056] In this embodiment, the flow guide 6 includes a first flow guide plate 61 and a second flow guide plate 62, which are connected in sequence. The angle of inclination between the first flow guide plate 61 and the plane where the shielding part 52 is located is greater than the angle of inclination between the second flow guide plate 62 and the plane where the shielding part 52 is located.

[0057] Specifically, the flow guide 6 is not a single sheet material, but a flow guide structure composed of a first flow guide plate 61 and a second flow guide plate 62. Both the first flow guide plate 61 and the second flow guide plate 62 are integrally formed with the shielding part 52 and are bent. Both the first flow guide plate 61 and the second flow guide plate 62 form a downward angle with the shielding part 52 along the burner height direction. Furthermore, the angle between the first flow guide plate 61 and the shielding part 52 is greater than the angle between the second flow guide plate 62 and the shielding part 52. The second flow guide plate 62 is located between the first flow guide plate 61 and the shielding part 52. That is, the first flow guide plate 61, with its larger angle of inclination, is further away from the shielding part 52. This allows the overflow to be guided by the second flow guide plate 62 when it drips onto the shielding part 52, while the first flow guide plate 61 accelerates the flow of the overflow, enabling it to drip more quickly from the shielding part 52 onto the collection tray 1, preventing overflow from accumulating on the shielding part 52.

[0058] In this embodiment, the extension 51 has a through hole 511 in the area where the nozzle 4 and the ejector tube 3 communicate. By providing the through hole 511, a passage is formed between the nozzle opening of the nozzle 4 and the opening of the ejector tube 3, avoiding the extension 51 being a flat closed plate that would block the passage, so that the nozzle 4 and the ejector tube 3 can be effectively connected, that is, gas is supplied into the ejector tube 3.

[0059] In this embodiment, the diameter of the through hole 511 is larger than the diameter of the ejector tube 3. By limiting the diameter of the through hole 511, it is to avoid the through hole 511 being too small, which would affect the supply of gas from the nozzle 4 to the ejector tube 3, and to prevent the extension 51 from generating gas flow resistance, which would have an adverse effect.

[0060] In this embodiment, the protective cover 5 also includes a connecting part 53. The connecting part 53 is integrally bent with the extension part 51 and the connecting part 53 is parallel to the surface of the liquid tray 1. A connecting hole 531 is provided on the connecting part 53. The connecting part 53 is connected to the liquid tray 1 by means of a bolt assembly passing through the connecting hole 531.

[0061] Specifically, the connecting part 53 is a rod integrally formed with the extension part 51 and bent. The connecting part 53 is parallel to the surface of the liquid tray 1 used to receive the protective cover 5. A connecting hole 531 is provided at the end of the connecting part 53 away from the extension part 51. The connecting part 53 can be bolted to the liquid tray 1 through a bolt assembly, thereby realizing the detachable connection between the protective cover 5 and the liquid tray 1.

[0062] In this embodiment, a slide (not shown in the figure) is provided on the liquid tray 1 corresponding to the connecting part 53, and a slider (not shown in the figure) is slidably arranged in the slide. The slider is connected to the connecting part 53 by a bolt assembly.

[0063] Specifically, the slide is a groove formed by the downward indentation of the surface of the liquid-receiving tray 1 receiving the protective cover 5 along the height direction of the burner. A slider is slidably disposed in the groove, and rollers are provided on the wall of the groove corresponding to the slider or on the surface of the slider to realize the slider sliding relative to the groove. The groove extends from the nozzle 4 to the ejector tube 3 so that when the connecting part 53 is connected to the slider by a bolt assembly, the protective cover 5 can slide along the groove.

[0064] Furthermore, in this embodiment, when the protective cover 5 slides along the slide and approaches the nozzle 4, the air intake of the ejector tube 3 is less than the air intake when the protective cover 5 slides along the slide and moves away from the nozzle 4.

[0065] Specifically, the extension 51 of the protective cover 5 is a plate, positioned between the nozzle 4 and the ejector tube 3, and can affect the primary air intake volume into the ejector tube 3. Although the through hole 511 on the extension 51 can prevent interference with the communication between the nozzle 4 and the ejector tube 3, because the extension 51 itself has a solid structure, when the protective cover 5 can slide along the track, the air intake volume of the ejector tube 3 is smaller when the protective cover 5 is close to the nozzle 4 (i.e., when the extension 51 is close to the nozzle 4), and larger when the protective cover 5 is away from the nozzle 4 (i.e., when the extension 51 is away from the nozzle 4). In this embodiment, the position of the protective cover 5 can be adjusted by the user manually sliding the protective cover 5 before cooking.

[0066] In other embodiments, an additional drive unit, such as a servo motor, may be provided. The servo motor is connected to the slider through a transmission structure and electrically connected to the control board of the burner to drive the slider to slide and thus drive the protective cover 5 to move. This allows the primary air intake of the ejector tube 3 to be adjusted when the protective cover 5 is sliding, thereby achieving the effect of a damper.

[0067] In this embodiment, the protective cover 5 is provided with a clearance groove 54 on the outer edge of the flame cap 2, and the clearance groove 54 extends from the extension portion 51 to the blocking portion 52.

[0068] Specifically, the outer edge of the flame cap 2 protrudes outward with a protrusion designed to contact the liquid tray 1, thereby improving the stability of the flame cap 2 on the liquid tray 1. The protrusion is a flat plate. For the protrusion, the protective cover 5 has a clearance groove 54, which prevents interference between the protective cover 5 and the flame cap 2 when it is installed on the liquid tray 1, and eliminates the need for the flame cap 2 or other structures to be displaced to avoid the protective cover 5. This ensures that the positions of the flame cap 2 and the nozzle 4 do not need to be changed, facilitating the updating of existing structures.

[0069] In this embodiment, the shielding part 52 is also provided with a clearance hole 521, which is provided on the top of the nozzle 4.

[0070] Specifically, the top of the nozzle 4 is provided with a protrusion that mates with the bottom of the flame cap 2. An avoidance hole 521 is provided to avoid the protrusion. When the protective cover 5 is mounted on the liquid collection tray 1, the protrusion extends into the avoidance hole 521 to seal the avoidance hole 521 and prevent overflow from dripping onto the nozzle 4. Simultaneously, when the protective cover 5 is mounted on the liquid collection tray 1, interference with the nozzle 4 is avoided.

[0071] In other embodiments, the diameter of the clearance hole 521 is slightly larger than the size of the protrusion. Since the nozzle orifice of the nozzle 4 is located on the side of the nozzle 4 and protrudes from the side surface, when the overflow drips from the clearance hole 521 into the top of the nozzle 4, the overflow can drip from the side of the nozzle 4 into the liquid collection tray 1 without entering the nozzle orifice, thus preventing the overflow from clogging the nozzle orifice.

[0072] In addition, the burner in this embodiment can also be controlled by a voice module. The burner is equipped with a control board, a voice receiving module, and a voice parsing module, which are common in the prior art. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller starts or stops the burner accordingly, thereby realizing intelligent control of the burner and improving the user experience.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
