[0003] In the prior art, an outdoor gas grill generally includes a furnace body, a combustion chamber is provided in the furnace body, and a burner is provided in the combustion chamber. Gas is transported to the burner head and burns at the fire hole of the burner head, thereby heating the air in the furnace body. The hot air formed by the heating is used to cook and grill the food on the grill on the furnace body.

[0004] However, in the prior art, the power of the burner is relatively small, which makes it difficult to meet the user's demand for higher temperature grilling. Utility Model Content

The gas flowing out of the fire hole corresponding to the fire gathering strip hole can flow to the fire gathering strip hole through the air guide gap.

[0011] Compared with the background technology, the burner head of the utility model has the following beneficial effects:

[0012] When the burner is in operation, the gas entering the fire tube flows out from the fire holes of the fire hole group. Because a fire gathering bar hole is provided corresponding to at least two fire holes of the fire hole group, the gas flowing out of the fire hole corresponding to the fire gathering bar hole can flow to the fire gathering bar hole through the gas guide gap. Therefore, each fire gathering bar hole can gather the gas flowing out of at least two fire holes. When the mixture of gas and air formed at each fire gathering bar hole is ignited, the flame is larger, thereby increasing the power of the burner and ensuring stable combustion of the burner even in a pressurized environment.

[0013] In one embodiment, the fire gathering member comprises:

[0014] A pressure plate extends along the first direction and is arranged at a relative interval on the outer side of the fire tube, and the fire gathering strip hole is penetrated by the pressure plate;

[0021] In one embodiment, the second sub-plate and the third sub-plate are in a "V"-shaped structure with the opening facing away from the fire tube, and the fire gathering strip hole is provided at the connection between the second sub-plate and the third sub-plate.

[0022] In one embodiment, two groups of fire hole groups are provided on the side of one end of the fire tube, and the two groups of fire hole groups are spaced apart along the second direction; one group of fire hole groups is provided on the side of the other end of the fire tube, and each of the fire hole groups is correspondingly provided with the fire gathering strip hole, and the second direction is perpendicular to the first direction.

[0023] In one embodiment, along the fire-emitting direction of the fire-gathering strip hole, the corresponding fire-gathering strip holes and the fire holes are staggered.

[0024] In one embodiment, the two inner side surfaces of the fire focusing strip hole extending along the first direction are arranged in a "V" shape.

[0025] The second technical problem mentioned above is solved by the following technical solution:

[0026] The oven comprises a furnace body, wherein the furnace body is provided with the above-mentioned furnace head.

[0027] Compared with the background technology, the oven described in the utility model has the following beneficial effects:

[0028] When the oven is in operation, the gas entering the fire tube of the burner flows out from the fire holes of the fire hole group. Because a fire gathering bar hole is provided corresponding to at least two fire holes of the fire hole group, the gas flowing out of the fire hole corresponding to the fire gathering bar hole can flow to the fire gathering bar hole through the gas guide gap. Therefore, each fire gathering bar hole can gather the gas flowing out of at least two fire holes. When the mixture of gas and air formed at each fire gathering bar hole is ignited, the flame is larger, thereby increasing the power of the burner and ensuring stable combustion of the burner even in a pressurized environment.

Therefore, they should not be understood as limitations on this application.

[0045] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. Throughout this application, unless otherwise specified, "plurality" means two or more.

[0046] In the description of this application, it should be noted that, unless otherwise specified or limited, the term "connection" should be understood in a broad sense. For example, it can mean a fixed connection, a detachable connection, or an integral connection; it can mean a mechanical connection or an electrical connection. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0047] This embodiment provides an oven.

[0048] Specifically, the oven is a gas oven.

[0049] See also Figure 1 and Figure 2 The oven comprises a furnace body 10, and a burner is arranged in the furnace body 10. The burner burns in the furnace body, heats the air in the furnace body, and thus heats the grill of the oven.

[0050] See also Figure 2-Figure 4 The burner head includes a fire tube 1 and a fire gathering part 2.

[0051] The fire tube 1 is provided with a plurality of fire hole groups, each of which includes a plurality of fire holes 11 spaced apart along a first direction.

[0052] The fire gathering piece 2 is arranged on the fire tube 1 and an air guide gap 3 is formed between the outer surface of the fire tube 1 and the fire gathering piece 2. The fire gathering piece 2 is provided with a plurality of fire gathering strip holes 23 arranged at intervals along the first direction. One fire gathering strip hole 23 is arranged corresponding to at least two fire holes 11 of the fire hole group. The gas flowing out of the fire hole 11 arranged corresponding to the fire gathering strip hole 23 can flow to the fire gathering strip hole 23 through the air guide gap 3.

[0053] It can be understood that one fire hole group is correspondingly provided with at least one fire gathering strip hole 23 . Furthermore, in this embodiment, one fire hole group is correspondingly provided with a plurality of fire gathering strip holes 23 .

[0054] Compared with the burner in the prior art, the burner provided in this embodiment has improved power and can also burn stably in a pressurized environment.

[0055] When the burner provided in this embodiment is in operation, the gas entering the fire tube 1 flows out from the fire holes 11 of the fire hole group. Since one fire gathering bar hole 23 is provided corresponding to at least two fire holes 11 of the fire hole group, the gas flowing out of the fire hole 11 corresponding to the fire gathering bar hole 23 can flow to the fire gathering bar hole 23 through the gas guide gap 3. Therefore, each fire gathering bar hole 23 can gather the gas flowing out of at least two fire holes 11. When the mixture formed by the gas and air at each fire gathering bar hole 23 is ignited, the flame is larger, thereby increasing the power of the burner and enabling the burner to burn stably even in a pressurized environment.

[0056] See also Figure 2 In one embodiment, the two inner side surfaces of the fire focusing hole 23 extending along the first direction are arranged in a "V" shape. This arrangement makes the fire focusing hole 23 a flared hole, which can not only guide the flow of air, but also facilitate the secondary replenishment of air in the area, ensuring sufficient combustion.

[0057] For example, Figure 2 In the embodiment, the two inner side surfaces of the fire focusing strip hole 23 extending along the first direction are respectively the first inner side surface 231 and the second inner side surface 232 , and the first inner side surface 231 and the second inner side surface 232 are arranged at an angle, which is an acute angle, a right angle or an obtuse angle.

[0058] Further, see Figure 2 and Figure 4 In one embodiment, the fire condenser 2 includes a pressure plate 21 and a side plate 22.

[0059] The pressing plate 21 extends along the first direction and is arranged at a relative interval on the outer side of the fire tube 1 . The fire focusing strip hole 23 is penetrated by the pressing plate 21 .

[0060] Side plates 22 are provided on opposite sides of the pressure plate 21 extending along the first direction. The free sides of the side plates 22 are connected to the outer side of the fire tube 1. The side plates 22, the pressure plate 21 and the outer side of the fire tube 1 form an air guide gap 3.

[0061] The side plates 22 , the pressure plate 21 and the outer side surfaces of the fire tube 1 are surrounded to form an air guide gap 3 to ensure that the gas flowing out of the fire hole 11 corresponding to the fire focusing strip hole 23 can flow to the fire focusing strip hole 23 through the air guide gap 3 .

[0062] Optionally, the side plate 22 is welded to the outer side of the fire tube 1. Further, optionally, the side plate 22 is welded to the outer side of the fire tube 1 by spot welding; the number of welding points can be multiple.

[0063] Furthermore, in one embodiment, the pressure plate 21 includes a first plate 211 and a second plate 212 arranged at an angle, the end of the first plate 211 away from the second plate 212 is connected to a side plate 22, and the side of the second plate 212 away from the first plate 211 is connected to the other side plate 22.

[0064] At least one of the first plate 211 and the second plate 212 is provided with a fire focusing hole 23, and the fire tube 1 is provided with a fire hole group corresponding to the fire focusing hole 23; and / or

[0065] A fire gathering hole 23 is provided at the connection between the first plate 211 and the second plate 212 , and a fire hole group corresponding to the fire gathering hole 23 is provided on the fire tube 1 .

[0066] The first plate 211 and the second plate 212 are arranged at an angle to ensure that the air guide gap 3 will have an inclined surface facing the outer side of the fire tube 1, ensuring the air compression effect of the pressure plate 21, and further ensuring that the gas flowing out of the fire hole 11 corresponding to the fire gathering strip hole 23 can flow through the air guide gap 3 to the fire gathering strip hole 23.

[0067] Optionally, in some embodiments, a fire gathering strip hole 23 is provided at least one of the first plate 211 and the second plate 212, and a fire hole group corresponding to the fire gathering strip hole 23 is provided on the fire tube 1. In some further embodiments, a fire gathering strip hole 23 is provided at the connection between the first plate 211 and the second plate 212, and a fire hole group corresponding to the fire gathering strip hole 23 is provided on the fire tube 1.

[0068] Specifically, in this embodiment, fire focusing holes 23 are provided on both the first plate 211 and the second plate 212. The fire tube 1 is provided with a group of fire holes corresponding to the fire focusing holes 23 on the first plate 211, and a group of fire holes corresponding to the fire focusing holes 23 on the second plate 212. Furthermore, a fire focusing hole 23 is provided at the junction of the first plate 211 and the second plate 212, and the fire tube 1 is provided with a group of fire holes corresponding to the fire focusing holes 23. This arrangement allows a large number of fire focusing holes 23 to be provided on the fire focusing member 2, ensuring a pressurizing effect.

[0069] For the convenience of description, the fire hole group on the fire tube 1 corresponding to the fire gathering strip holes 23 on the first plate 211 is called the first fire hole group, the fire hole group on the fire tube 1 corresponding to the fire gathering strip holes 23 on the second plate 212 is called the second fire hole group, and the fire hole group on the fire tube 1 corresponding to the fire gathering strip holes 23 at the connection between the first plate 211 and the second plate 212 is called the third fire hole group.

[0070] The number of fire holes 11 in the first fire hole group, the second fire hole group and the third fire hole group can be the same or different; the arrangement positions can be the same (such as all arranged from one end to the other end of the fire tube 1) or different, and can be set as needed without making too many restrictions here.

[0071] Optionally, in one embodiment, two groups of fire holes are provided on the side of one end of the fire tube 1, and the two groups of fire holes are spaced apart along the second direction; a group of fire holes is provided on the side of the other end of the fire tube 1, and each fire hole group is provided with a corresponding fire gathering strip hole 23, and the second direction is perpendicular to the first direction.

[0072] Specifically, the first direction is parallel to the axial direction of the fire tube 1 , and the second direction is parallel to the radial direction of the fire tube 1 .

[0073] Specifically, Figure 3 and Figure 5 As an example, the first direction is parallel to Figure 3 The upper side of the fire tube 1 is provided with two groups of fire hole groups, which are the first fire hole group and the second fire hole group, and the first fire hole group and the second fire hole group are spaced along the second direction; the lower side of the fire tube 1 is provided with a group of fire hole groups, which is the third fire hole group.

[0074] Furthermore, in actual use, the first fire hole group and the second fire hole group are arranged at the end of the fire tube 1 close to the gas source, and the third fire hole group is arranged at the end of the fire tube 1 away from the gas source. Since the end of the fire tube 1 close to the gas source has sufficient gas supply, two fire hole groups are arranged at this end to ensure that the airflow entering the fire tube 1 flows fully to the various fire gathering strip holes 23 corresponding to these two groups of fire hole groups. The end of the fire tube 1 away from the gas source has relatively less gas supply, and only one fire hole group is arranged at this end. Such an arrangement can ensure the uniformity of the gas supply to each fire gathering strip hole 23, thereby ensuring that the combustion state of the flame at each fire gathering strip hole 23 is basically consistent, and ultimately ensuring the temperature uniformity of the combustion of the entire burner.

[0075] Further, see Figure 2 In one embodiment, the first plate 211 is a V-shaped structure with its opening facing the fire tube 1, comprising a first split plate 2111 and a second split plate 2112 arranged at an angle. The side of the first split plate 2111 away from the second split plate 2112 is connected to a side plate 22, and the side of the second split plate 2112 away from the first split plate 2111 is connected to the second plate 212. A fire focusing hole 23 is provided at the junction of the first split plate 2111 and the second split plate 2112. The first fire hole group is provided corresponding to the fire focusing hole 23 at this location.

[0076] The inner side surfaces of the first sub-plate 2111 and the second sub-plate 2112 can form air compression slopes.

[0077] Further, see Figure 2In one embodiment, the second plate 212 has a V-shaped structure with its opening facing the fire tube 1 and includes a third split plate 2121 and a fourth split plate 2122 arranged at an angle. The side of the third split plate 2121 facing away from the fourth split plate 2122 is connected to the second split plate 2112, and the side of the fourth split plate 2122 facing away from the third split plate 2121 is connected to the other side plate 22. A fire focusing hole 23 is provided at the junction of the third split plate 2121 and the fourth split plate 2122. The second fire hole group is provided corresponding to the fire focusing hole 23 at this location.

[0078] The third split plate 2121 and the fourth split plate 2122 can both form compressed air slopes.

[0079] Furthermore, in one embodiment, the second and third split plates 2112 and 2121 are V-shaped with their openings facing away from the fire tube 1, and a fire focusing hole 23 is provided at the connection between the second and third split plates 2112 and 2121. The third fire hole group is provided corresponding to the fire focusing hole 23 at the connection.

[0080] With such arrangement, the "V"-shaped structure there can also form a compressed air structure, which fully ensures that the gas flowing out from the fire hole 11 corresponding to this location can flow to the fire gathering strip hole 23 at the connection between the second sub-plate 2112 and the third sub-plate 2121, thereby ensuring the fire gathering effect of the fire gathering strip hole 23 there.

[0081] In this embodiment, the cross-sectional shape of the fire gathering member 2 is roughly "M"-shaped, which can effectively disturb the gas flow path in the gas guide gap 3, ensure the uniformity of the gas flowing to each fire gathering strip hole 23, and thus ensure the combustion uniformity at each fire gathering strip hole 23.

[0082] In one embodiment, see Figure 5-Figure 7 Along the fire-emitting direction of the fire-gathering strip hole 23, the corresponding fire-gathering strip hole 23 and the fire hole 11 are staggered.

[0083] It should be noted that, along the fire-emission direction of the fire-emission strip hole 23, the staggered arrangement of the corresponding fire-emission strip hole 23 and the fire hole 11 means that, projected along the fire-emission direction of the fire-emission strip hole 23, the projections of the corresponding fire-emission strip hole 23 and the fire hole 11 are completely staggered or partially overlapped, and the two are not arranged directly opposite each other.

[0084] Such arrangement prevents the gas flowing out of the fire hole 11 from flowing directly to the fire focusing strip hole 23 in a straight line. The gas flowing out of the fire hole 11 first impacts the inner surface of the pressure plate 21 and is then pressed down by the pressure plate 21. After the air flow flows evenly in the air guide gap, it flows along the air guide gap to the fire focusing strip hole 23, ensuring the uniformity and stability of the gas flowing out of each fire focusing strip hole 23, thereby avoiding adverse phenomena such as backfire or flame separation of the flame at the fire focusing strip hole 23 during ignition.

[0085] In one embodiment, see Figure 6 and Figure 7 With the center point of the cross section of the fire tube 1 as the center of the circle, the central angle of the fire focusing strip hole 23 is greater than the central angle of the fire hole 11. This arrangement makes the flow cross section of the fire focusing strip hole 23 larger. Since one fire focusing strip hole 23 corresponds to multiple fire holes 11, the larger the flow cross section of the fire focusing strip hole 23, the more air can flow out, thereby ensuring a larger flame at the fire focusing strip hole 23, and thus improving the power of the burner.

[0086] For example, Figure 7 In the figure, the cross-sectional center point of the fire tube 1 is point C, and the angle α represents the central angle of the fire hole 11 with the cross-sectional center point of the fire tube 1 as the center of the circle; the angle β represents that the central angle of the fire focusing strip hole 23 is greater than the central angle of the fire hole 11 with the cross-sectional center point of the fire tube 1 as the center of the circle.

[0087] Angles α and β can be completely different or can be Figure 7 The partially overlapping state.

[0088] Furthermore, in one embodiment, with the cross-sectional center point of the fire tube 1 as the center of the circle, the central angle of the fire focusing strip hole 23 is greater than the central angle of the fire hole 11; that is, the angle β is greater than the angle α.

[0089] Optionally, the difference between the angle β and the angle α is 5°-10°. Exemplarily, the difference between the two can be 5°, 6°, 7°, 8°, 9° or 10°.

[0090] Of course, in other embodiments, the difference between the angle β and the angle α may also be set to other values as needed, which will not be described in detail here.

[0091] Specifically, see Figure 8 , Figure 8 When the fire tube 1 burns stably, each fire-gathering strip hole 23 is an arc-shaped flame 100, and the shapes of the flames 100 at each location are basically the same, and the combustion is stable.

[0092] In the prior art, the maximum power of a burner with only a fire hole and burning at the fire hole is about 3.5Kw, which can only heat the local temperature of the grill of the oven to 350℃-400℃, and cannot meet the needs of users who like to grill food at high temperatures.

[0093] The burner in this embodiment can achieve stable combustion in a pressurized environment (e.g., at a gas pressure of 50 mbar), with a burner power of over 4.5 kW, without experiencing abnormal combustion conditions such as flashback or flameout. This burner can raise the grilling zone temperature to over 500°C, significantly enhancing the user's grilling experience and meeting their high-temperature grilling needs.

[0094] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0095] The specific contents of the above-mentioned specific embodiments only express several embodiments of the present invention. Although the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the appended claims.
