[0037] Reference Figures 1 to 6 As shown, this embodiment provides a gas oven, which includes an oven body 100, an upper cover 200, and a heat reflector 300.

[0038] Specifically, the oven body 100 is provided with a grilling cavity 110; the upper cover 200 is rotatably connected to the oven body 100 and opens or closes the grilling cavity 110. When the upper cover 200 closes the grilling cavity 110, a smoke outlet gap 101 communicating with the grilling cavity 110 is formed between the rear end of the upper cover 200 and the oven body 100; the heat reflector 300 is provided at the lower rear end of the upper cover 200 and is used to reflect the heat of the smoke flowing through the grilling cavity 110.

[0039] In this embodiment, the heat from the flue gas flowing through the heat reflector 300 in the reflective grilling cavity 110 is immediately reflected by the heat reflector 300, which facilitates the circulation of heat throughout the grilling cavity 110. The heat reflector 300 is positioned at the lower rear end of the upper cover 200 so that it is close to the smoke outlet gap 101. When grilling in the gas oven, some of the flue gas flowing towards the smoke outlet gap 101 in the grilling cavity 110 will flow to the heat reflector 300, effectively reducing heat loss, improving heating speed and thermal efficiency, and allowing food to be cooked faster, providing users with a better grilling experience.

[0040] For example, the height H of the smoke outlet gap 101 can be 5mm-15mm, such as 8mm or 10mm, which can reduce the heat loss of the grilling cavity 110 and reduce the concentration of carbon monoxide in the grilling cavity 110.

[0041] For example, the heat reflector 300 has an aluminum-plated layer on its surface. After absorbing a certain amount of heat, the surface layer reflects 80% of the incident heat back. For example, the heat reflector 300 can be an aluminum-plated steel plate.

[0042] In this embodiment, reference is made to Figure 1 As shown, the upper cover 200 includes a rear end plate 211. When the upper cover 200 closes the grilling cavity 110, a smoke outlet gap 101 communicating with the grilling cavity 110 is formed between the lower part of the rear end plate 211 and the oven body 100. The heat reflector plate 300 includes a plate body 310 that abuts against the rear end plate 211, and the plate body 310 is located on the lower inner side of the rear end plate 211. In this embodiment, by placing the plate body 310 on the lower inner side of the rear end plate 211, the user can rotate the upper cover 200 with less effort. Of course, the heat reflector plate 300 can also be located in other positions on the upper cover 200, and this embodiment is not limited to this.

[0043] In this embodiment, reference is made to Figures 2 to 3 As shown, guide plates 320 are connected to both long sides of the plate body 310. The guide plates 320 protrude from the side of the plate body 310 away from the rear end plate 211. Furthermore, along a direction perpendicular to the plate body 310, the projection of the plate body 310 onto the rear end plate 211 does not coincide with the projection of the guide plate 320 onto the rear end plate 211. When the upper cover 200 closes the grilling cavity 110, the guide plate 320 located below the plate body 310 approaches the smoke outlet gap 101. In this embodiment, the plate body 310 and the guide plate 320 reflect heat in different directions, and the guide plate 320 can guide the heat reflected by the heat reflector 300, which is more conducive to heat circulation throughout the grilling cavity 110, further reducing heat loss and improving thermal efficiency. In addition, the guide plate 320 can also increase the structural strength of the heat reflector 300, effectively preventing the heat reflector 300 from deforming and reducing its thermal efficiency.

[0044] In one feasible implementation, the guide plate 320 is configured as an arc-shaped plate, with the guide plate 320 recessed from the side away from the rear end plate 211 towards the side facing the rear end plate 211. This facilitates heat circulation throughout the grilling cavity 110, reduces heat loss, and improves thermal efficiency. Alternatively, the guide plate 320 can also be recessed from the side away from the rear end plate 211 towards the side facing the rear end plate 211. It is understood that when the heat reflector plate 300 is mounted on the rear end plate 211, the guide plate 320 is recessed from the side away from the rear end plate 211 towards the side facing the rear end plate 211.

[0045] In one feasible implementation, such as Figure 4 As shown, the guide plate 320 is a flat plate, and the guide plate 320 is set at an angle to the plate body 310 to facilitate the circulation of heat in the entire grilling cavity 110, reduce heat loss, and improve thermal efficiency.

[0046] For example, the included angle α between the plate body 310 and the guide plate 320 is set to 100°-135°, such as 105°, 110°, 115°, 120° or 130°, so as to improve the thermal efficiency.

[0047] In this embodiment, reference is made to Figure 1 , Figure 3 and Figure 4 As shown, the heat reflector 300 can be fixed to the upper cover 200 via a connector (not shown). Specifically, the heat reflector 300 is provided with a first mounting hole 301, and the upper cover 200 is provided with a second mounting hole (not shown). The heat reflector 300 is connected to the upper cover 200 by passing through the first mounting hole 301 and the second mounting hole via the connector, which facilitates the assembly of the heat reflector 300 and ensures a stable and reliable connection.

[0048] For example, the connectors include, but are not limited to, screws or rivets.

[0049] In one feasible embodiment, the two short sides of the plate body 310 are bent toward the side opposite to the rear end plate 211 to form a fixing plate 330. The fixing plate 330 is provided with a first mounting hole 301. The fixing plate 330 is connected to the upper cover 200 by means of a connector passing through the first mounting hole 301 and a second mounting hole. In this embodiment, in addition to being used to connect with the upper cover 200, the fixing plate 330 can also increase the structural strength of the heat reflector 300, and more effectively prevent the heat reflector 300 from reducing its thermal efficiency due to deformation.

[0050] Specifically, the top cover 200 also includes side plates 220 disposed on both sides of the rear end plate 211. The side plates 220 are provided with second mounting holes, and the fixing plate 330 is flush with the corresponding side plate 220. In this embodiment, the fixing plate 330 abuts against the corresponding side plate 220 and is connected by a connector, which effectively ensures a stable and reliable connection between the heat reflector plate 300 and the top cover 200, and facilitates assembly.

[0051] For example, the plate body 310 and the fixing plate 330 are perpendicular to each other. Of course, depending on the angular relationship between the side plate 220 and the rear end plate 211, the plate body 310 and the fixing plate 330 can also be set at other included angles, which is not limited in this embodiment.

[0052] In one feasible implementation, the heat reflector 300 has a symmetrical structure, which provides good error prevention and effectively prevents the heat reflector 300 from being installed in the wrong orientation relative to the upper cover 200, thus facilitating assembly. Exemplarily, the outline of the fixing plate 330 includes, but is not limited to, a triangle, trapezoid, or semicircle.

[0053] In one feasible implementation, the first mounting hole 301 is an elongated hole, and the first mounting hole 301 extends in a direction perpendicular to the plate body 310, so as to facilitate the adjustment of the position of the heat reflector plate 300 relative to the upper cover 200, so as to achieve the abutment between the heat reflector plate 300 and the rear end plate 211.

[0054] In one feasible implementation, the second mounting hole is designed as an elongated hole, and the extension direction of the second mounting hole is perpendicular to the extension direction of the first mounting hole 301, so as to facilitate the adjustment of the height of the heat reflector 300 relative to the smoke outlet gap 101.

[0055] In one feasible implementation, a clearance hole 302 is provided at the bend between the plate body 310 and the fixing plate 330, and the clearance hole 302 is connected to the first mounting hole 301. The clearance hole 302 can avoid screws or rivets on the top cover 200 to avoid positional interference and affect the abutment between the plate body 310 and the rear end plate 211.

[0056] For example, the distance b1 between the inner walls of the two sides of the clearance hole 302 along the width direction of the plate body 310 is greater than the width b2 of the first mounting hole 301, so as to better avoid screws or rivets.

[0057] In this embodiment, reference is made to Figure 1 As shown, the top cover 200 also includes a front end plate 212 and a middle plate 213. The front end plate 212, the middle plate 213 and the rear end plate 211 are bent and connected to form the cover body. Two side plates 220 are respectively provided on both sides of the cover body.

[0058] Specifically, the side plate 220 is rotatably connected to the furnace body 100 on the side near the rear end plate 211.

[0059] Specifically, to facilitate users in opening or closing the barbecue cavity 110, a handle 230 is provided on the front panel 212.

[0060] In one feasible implementation, such as Figure 2 , Figure 5 and Figure 6 As shown, when the upper cover 200 closes the grilling cavity 110, the heat reflector 300 is lower than the lower rear end of the upper cover 200 and partially blocks the smoke outlet gap 101. This allows the heat reflector 300 to guide the smoke flowing towards the smoke outlet gap 101, which is more conducive to heat circulation throughout the grilling cavity 110, further reducing heat loss and improving thermal efficiency. It is understandable that if the heat reflector 300 were higher than the lower rear end of the upper cover 200, its heat reflection effect would be poor, resulting in a less effective improvement in thermal efficiency and affecting the user's grilling experience.

[0061] Specifically, when the top cover 200 closes the grill cavity 110, the guide plate 320 located below the plate body 310 is lower than the lower rear end of the top cover 200.

[0062] For example, taking the abutment between the plate body 310 and the rear end plate 211 of the upper cover 200 as an example, when the upper cover 200 closes the grilling cavity 110, the heat reflector 300 is lower than the lower part of the rear end plate 211, and the heat reflector 300 is flush with the lower part of the side plate 220 of the upper cover 200. In this embodiment, the flushness between the heat reflector 300 and the lower part of the side plate 220 of the upper cover 200 can effectively ensure that the shielding area of ​​the heat reflector 300 on the smoke outlet gap 101 is not too large, so that the smoke can be smoothly discharged from the smoke outlet gap 101 into the grilling cavity 110, preventing the concentration of carbon monoxide in the grilling cavity 110 from being too high. In addition, the heat reflector 300 is positioned at the lower part of the side plate 220 to achieve the positioning and assembly of the heat reflector 300 relative to the upper cover 200, and effectively prevent the heat reflector 300 from interfering with the position of the oven body 100 when the upper cover 200 rotates.

[0063] Specifically, the guide plate 320 located below the plate body 310 is lower than the lower part of the rear end plate 211 and flush with the lower part of the side plate 220.

[0064] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0065] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
