Description
Technical Field
[0001] The utility model relates to the technical field of stoves, in particular to a burner and a stove comprising the burner. Background Art
[0002] A fire transfer hole is arranged on the fire cover of the burner in the stove. The mixed gas of the fuel gas and the air is mixed in the gas mixing chamber and then flows out through the fire transfer hole and is ignited to form a combustion flame.
[0003] However, since the flame transmission holes are usually exposed, when users are cooking, impurities such as soup overflow, oil stains, etc. can easily fall on the flame cover of the gas burner, thereby blocking the flame transmission holes and preventing the normal combustion of the burner, which not only affects the user's normal cooking but also poses a safety hazard. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the defect that the flame transfer hole of the burner in the prior art is easily blocked, and to provide a burner and a stove including the same.
[0005] The utility model solves the above technical problems through the following technical solutions:
[0006] A burner, comprising an inner ring fire cover and an outer ring fire cover, wherein the outer ring fire cover is arranged around the outer circumference of the inner ring fire cover; the inner ring fire cover and the outer ring fire cover both comprise a fire cover body, a protrusion and a plurality of fire transfer holes; the protrusion is arranged around the outer circumference of the fire cover body and is connected to the fire cover body; a plurality of the fire transfer holes are arranged along the circumference of the fire cover body, and any of the fire transfer holes passes through from the inner side of the fire cover body to the outer side of the protrusion; the protrusion is provided with an overflow groove, which extends in a vertical direction and is connected to the bottom of the protrusion; the overflow groove is arranged around the outer circumference of the fire cover body and is intersectingly connected with any of the fire transfer holes.
[0007] In this solution, through the above-mentioned structural form, when the user is cooking, the soup overflow and other impurities first splash onto the protrusion. Since the fire transmission hole is connected to the overflow groove and the overflow groove extends in the vertical direction, the impurities splashed into the fire transmission hole on the protrusion can flow down from the bottom of the protrusion along the overflow groove under the action of gravity, and will not flow into the fire transmission hole on the fire cover body, ensuring that the fire transmission hole is not blocked and the fire can be normally produced. In addition, the inner ring fire cover and the outer ring fire cover in this solution are both provided with a protrusion with an overflow groove, which has a better anti-blocking effect.
[0008] Preferably, the overflow groove passes through the fire transfer hole in a vertical direction.
[0009] In this solution, through the above-mentioned structural form, the overflow groove completely separates the fire transfer hole in the axial direction into two parts located at the protrusion and the fire cover body, thereby preventing overflow impurities from flowing from the protrusion into the fire cover body along the upper inner wall of the fire transfer hole.
[0010] Preferably, the protrusion includes a top; the top is arranged around the outer circumference of the fire cover body and is located above the fire transfer hole; the inner circumference of the top is connected to the fire cover body and extends radially outwardly along the fire cover body.
[0011] In this solution, since the top portion extends radially outwardly along the fire cover body, a vertical shield is provided above the fire transfer hole, thereby preventing overflow impurities from falling vertically into the fire transfer hole in the fire cover body.
[0012] Preferably, in the outer ring fire cover, the top portion extends from the edge of the top wall of the fire cover body and is inclined in a direction pointing vertically upward and in a radial direction outward of the fire cover body.
[0013] In the present solution, through the above-mentioned structural form, the overflow impurities falling on the top can flow toward the radial inner side of the fire cover body or the top wall of the fire cover body as much as possible, reducing the possibility of flowing to the fire transfer holes on the protrusion; and the overflow impurities flowing to the top wall of the fire cover body is also convenient for users to clean.
[0014] Preferably, in the inner ring fire cover, the top portion extends horizontally from the edge of the top wall of the fire cover body and is flush with the top wall of the fire cover body.
[0015] In this solution, the top of the protrusion in the inner ring fire cover is flush with the top wall of the fire cover body, which reduces the difficulty of manufacturing the inner ring fire cover.
[0016] Preferably, the protrusion also includes a baffle ring; the baffle ring is connected to the outer periphery of the top, and the baffle ring extends in a vertical downward direction; the fire transfer hole extends to the radially outer side of the baffle ring; the baffle ring is spaced a predetermined distance from the outer periphery of the fire cover body to form the overflow groove between the baffle ring, the top and the outer periphery of the fire cover body.
[0017] In the present scheme, the baffle ring, the top and the outer periphery of the fire cover body form an overflow groove with a notch pointing downward, which has a simple structure and is easy to manufacture; the baffle ring surrounds the outer periphery of the fire cover body, that is, it provides a shield in the radial direction of the fire transfer hole of the fire cover body. When overflow impurities splash onto the baffle ring, some of the impurities can slide vertically downward along the outer peripheral wall of the baffle ring, and some impurities flow into the overflow groove through the fire transfer hole on the baffle ring, and slide vertically downward along the groove wall of the overflow groove (or along the inner peripheral wall of the baffle ring), thereby avoiding clogging the fire transfer hole on the fire cover body.
[0018] Preferably, the diameter of the fire transfer hole on the protruding portion is larger than the diameter of the fire transfer hole on the fire cover body.
[0019] In this solution, the above-mentioned structural form allows the flame to pass through the flame transfer holes on the protrusion to the greatest extent, thereby reducing heat loss.
[0020] Preferably, the fire transfer holes are inclined in directions pointing vertically upward and radially outward of the fire cover body.
[0021] In this solution, the above-mentioned structural form facilitates the flame formed by the combustion of gas to spray upward, which is beneficial to heating the pot and the like located above the burner.
[0022] Preferably, the outer ring fire cover also includes a flame stabilizing groove; the flame stabilizing groove extends in the horizontal direction and is arranged circumferentially around the fire cover body in the outer ring fire cover, and the flame stabilizing groove is connected to the circumferential side wall of the fire transfer hole.
[0023] In this solution, by providing a flame stabilizing groove connected to the circumferential side wall of the fire transfer hole, secondary air can be added to the flame in the fire transfer hole in time to maintain flame stability.
[0024] A stove comprises the burner as described above.
[0025] In this solution, when the stove is used for cooking, the overflow impurities dropped from the pots and the like on the stove are not likely to clog the fire outlet of the burner, thus ensuring the normal use of the stove.
[0026] The positive and progressive effects of the utility model are:
[0027] By providing a protrusion with an overflow groove on the outer periphery of the fire cover body, when the user is cooking, impurities such as overflowed soup will first splash onto the protrusion. Since the fire transmission hole is connected to the overflow groove and the overflow groove extends in the vertical direction, the impurities splashed into the fire transmission hole on the protrusion can flow down from the bottom of the protrusion along the overflow groove under the action of gravity, and will not flow into the fire transmission hole on the fire cover body, ensuring that the fire transmission hole is not blocked and the fire can be normally emitted. In addition, the protrusion with the overflow groove is provided on both the inner ring fire cover and the outer ring fire cover, and the anti-blocking effect is better.

[0041] The present invention will be described more clearly and completely below through embodiments in conjunction with the accompanying drawings.
[0042] like Figure 1-Figure 3 As shown, this embodiment provides a burner, which includes an inner ring fire cover 10 and an outer ring fire cover 20. The outer ring fire cover 20 is arranged around the outer periphery of the inner ring fire cover 10; the inner ring fire cover 10 and the outer ring fire cover 20 both include a fire cover body 30, a protrusion 40 and a plurality of fire transfer holes 60.
[0043] The protrusion 40 is arranged around the outer circumference of the fire cover body 30 and is connected to the fire cover body 30; a plurality of fire transfer holes 60 are arranged along the circumference of the fire cover body 30, and any fire transfer hole 60 passes through from the inner side of the fire cover body 30 to the outer side of the protrusion 40; the protrusion 40 is provided with an overflow groove 50, which extends in a vertical direction and is connected to the bottom of the protrusion 40; the overflow groove 50 is arranged around the outer circumference of the fire cover body 30, and is intersected and connected with any fire transfer hole 60.
[0044] With the above-mentioned structure, when the user is cooking, the soup overflow and other impurities first splash onto the protrusion 40. Since the fire transmission hole 60 is connected to the overflow groove 50 and the overflow groove 50 extends in the vertical direction, the impurities splashed into the fire transmission hole 60 on the protrusion 40 can flow down from the bottom of the protrusion 40 along the overflow groove 50 under the action of gravity, and will not flow into the fire transmission hole 60 on the fire cover body 30, ensuring that the fire transmission hole 60 is not blocked and can be fired normally. In addition, both the inner ring fire cover 10 and the outer ring fire cover 20 are provided with the protrusion 40 with the overflow groove 50, and the anti-blocking effect is better.
[0045] Specifically, the protruding portion 40 includes a top portion 41 and a retaining ring 42 .
[0046] The top portion 41 is disposed around the outer circumference of the fire cover body 30 and is located above the fire transfer hole 60 ; the inner circumference of the top portion 41 is connected to the fire cover body 30 and extends outwardly along the radial direction of the fire cover body 30 .
[0047] The baffle ring 42 is connected to the outer periphery of the top 41 , and the baffle ring 42 extends in a vertical downward direction; the fire transfer hole 60 extends to the radial outer side of the baffle ring 42 .
[0048] The baffle ring 42 is spaced apart from the outer periphery of the fire cover body 30 by a predetermined distance, so that an overflow groove 50 is formed between the baffle ring 42 , the top portion 41 and the outer periphery of the fire cover body 30 .
[0049] Since the top 41 extends radially outwardly along the fire cover body 30, that is, it provides a vertical shielding above the fire transfer hole 60, preventing the overflow impurities from falling in the vertical direction and flowing into the fire transfer hole 60 in the fire cover body 30. The baffle ring 42 surrounds the outer circumference of the fire cover body 30, that is, it provides a shielding in the radial direction of the fire transfer hole 60 of the fire cover body 30. When the overflow impurities splash on the baffle ring 42, some of the impurities can slide vertically downward along the outer peripheral wall of the baffle ring 42, and some of the impurities flow into the overflow groove 50 through the fire transfer hole 60 on the baffle ring 42, and slide vertically downward along the groove wall of the overflow groove 50 (or along the inner peripheral wall of the baffle ring 42), avoiding blocking the fire transfer hole 60 on the fire cover body 30.
[0050] The overflow groove 50 with the notch downward is formed by the retaining ring 42, the top 41 and the outer periphery of the fire cover body 30, which has a simple structure and is easy to manufacture. There are many ways to manufacture the overflow groove 50. In this embodiment, the fire cover body 30 and the protrusion 40 are integrally formed when the burner is manufactured, and then the bottom of the protrusion 40 is excavated in a vertically upward direction to form the overflow groove 50 (the bottom of the overflow groove 50 is the top 41, and the groove walls on both sides of the overflow groove 50 are the outer peripheral wall of the fire cover body 30 and the inner peripheral wall of the retaining ring 42), thereby increasing the integrity of the burner; in other optional embodiments, the protrusion 40 can also be manufactured independently (or the top 41 and the retaining ring 42 are manufactured at a certain angle), and then the protrusion 40 (or the inner periphery of the top 41) is connected to the fire cover body 30 by welding or other methods.
[0051] The distance that the top 41 extends radially outward from the fire cover body 30 is the distance between the baffle ring 42 and the outer periphery of the fire cover body 30, that is, the width of the overflow groove 50. If this distance is too small, the effect of the overflow groove 50 will be affected, and some overflow impurities may directly pass through the overflow groove 50 from the fire transfer hole 60 on the baffle ring 42 and directly enter the fire transfer hole 60 on the fire cover body 30; if this distance is too large, it will not only waste manufacturing materials, but also easily affect the ignition of the fire transfer hole 60. Therefore, the distance between the baffle ring 42 and the outer periphery of the fire cover body 30 can be selected according to actual conditions. In this embodiment, this distance is selected to be 1-3 cm.
[0052] The distance that the retaining ring 42 extends in the vertical downward direction is the height of the retaining ring 42 . The height of the retaining ring 42 is set such that the projection of the retaining ring 42 on the fire cover body 30 at least partially covers the fire transfer holes 60 on the fire cover body 30 in the vertical direction.
[0053] In other optional embodiments, the protrusion 40 may also have other structural forms:
[0054] In this embodiment, the retaining ring 42 extends in the vertical direction as the outer peripheral wall of the protrusion 40. In other optional embodiments, the outer peripheral wall of the protrusion 40 may also be set to be inclined or in other shapes;
[0055] In this embodiment, the bottom end of the retaining ring 42 is directly spaced apart from the outer periphery of the fire cover body 30 to form a notch of the overflow groove 50, so as to realize the connection between the overflow groove 50 and the bottom of the protrusion 40. The notch of the overflow groove 50 is the bottom of the protrusion 40. In other optional embodiments, the bottom of the protrusion 40 can be connected with the overflow groove 50, and a liquid collecting groove can also be provided to collect the overflow impurities for unified cleaning.
[0056] Specifically, in the outer ring fire cover 20 , the top portion 41 extends from the top wall edge of the fire cover body 30 and is inclined in a direction pointing vertically upward and in a radial direction outward of the fire cover body 30 .
[0057] Through the above-mentioned structural form, the overflow impurities falling on the top 41 can flow toward the radial inner side of the fire cover body 30 or the top wall of the fire cover body 30 as much as possible, reducing the possibility of flowing to the fire transfer hole 60 on the protrusion 40; and the overflow impurities flowing to the top wall of the fire cover body 30 is also convenient for users to clean.
[0058] In the inner ring fire cover 10 , the top portion 41 extends from the edge of the top wall of the fire cover body 30 in the horizontal direction and is flush with the top wall of the fire cover body 30 .
[0059] Compared with the outer ring fire cover 20 , the risk of the fire transfer hole 60 in the inner ring fire cover 10 being blocked is lower. Making the top 41 of the protrusion 40 in the inner ring fire cover 10 flush with the top wall of the fire cover body 30 not only saves materials but also reduces the manufacturing difficulty of the inner ring fire cover 10 .
[0060] Furthermore, the diameter of the fire transfer hole 60 on the protrusion 40 is larger than the diameter of the fire transfer hole 60 on the fire cover body 30, so that the flame can pass through the fire transfer hole 60 on the protrusion 40 to the greatest extent, reducing heat loss.
[0061] Furthermore, the flame transfer hole 60 is inclined in a direction pointing vertically upward and radially outward of the fire cover body 30, so that the flame formed by the combustion of the gas can be ejected upward, which is beneficial to heating the pot and the like located above the burner.
[0062] Furthermore, in this embodiment, the overflow groove 50 passes through the fire transfer hole 60 in the vertical direction.
[0063] In other optional embodiments, the overflow groove 50 may also be vertically connected only with the peripheral side wall on the lower side of the fire transfer hole 60 .
[0064] The overflow groove 50 penetrates the fire transfer hole 60 in the vertical direction, that is, it is connected with the peripheral side walls on the lower side and the upper side of the fire transfer hole 60. The overflow groove 50 completely divides the fire transfer hole 60 in the axial direction into two parts located at the protrusion 40 and located on the fire cover body 30. Compared with the overflow groove 50 only intersecting and communicating with the peripheral side wall on the lower side of the fire transfer hole 60, the overflow groove 50 penetrates the fire transfer hole 60 in the vertical direction, which can prevent the overflow impurities from flowing from the protrusion 40 to the fire cover body 30 along the peripheral side wall on the upper side of the fire transfer hole 60. Therefore, the method selected in this embodiment is the most preferred.
[0065] Furthermore, the outer ring fire cover 20 also includes a flame stabilizing groove 70 ; the flame stabilizing groove 70 extends in the horizontal direction and is circumferentially arranged around the fire cover body 30 in the outer ring fire cover 20 , and the flame stabilizing groove 70 is connected to the circumferential side wall of the fire transfer hole 60 .
[0066] By providing the flame stabilizing groove 70 connected to the circumferential side wall of the fire transfer hole 60 , secondary air can be added to the flame in the fire transfer hole 60 in time to maintain flame stability.
[0067] This embodiment also provides a stove, which includes the burner as described above.
[0068] Therefore, when the stove is used for cooking, the overflow impurities dropped from the pots and the like on the stove are not easy to block the fire outlet of the burner, thus ensuring the normal use of the stove.
[0069] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by terms such as "upper", "lower", "radial", "vertical", "horizontal", "top", "bottom", "inside" and "outside" are based on the conventional positional relationships when the stove and the burner are installed and placed in accordance with the conventional usage method.

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.
