Description

Technical Field

[0001] This utility model belongs to the field of barbecue oven technology, and more specifically, relates to a foldable barbecue oven. Background Technology

[0002] A foldable barbecue grill has been proposed. For example, Patent Document 1, Japanese Utility Model Registration No. 3215288, discloses a barbecue grill in which the front wall, rear wall, first side wall, and second side wall can be rotatably mounted relative to a frame. In the barbecue grill described in Patent Document 1, when in use, the front wall, rear wall, first side wall, and second side wall are rotated around their pivots to open and then fixed, based on the frame, thereby achieving an unfolded state. After use, the front wall, rear wall, first side wall, and second side wall are rotated in the opposite direction to the unfolded state and overlapped to achieve a folded state.

[0003] The foldable barbecue grill described in Patent Document 1 has a problem: the opening and closing operation is not simple enough. When switching from the folded state to the unfolded state, each wall needs to be rotated to an appropriate angle to unfold and fit together to fix it. Since the barbecue grill is used in a high-temperature environment, the frame and each wall may deform with the increase of use, making the unfolding operation difficult or making it difficult for the parts to fit together and fix accurately.

[0004] Switching from the unfolded to the folded state is typically done after the grill has been used. During use, the grill is at a high temperature, and it takes time for it to cool down to room temperature. However, in some cases, due to time constraints, users need to store the grill before it has fully cooled down. To fold the grill described in Patent Document 1, the interlocking parts between the walls need to be disassembled first, and then each wall needs to be folded and stored one by one. This is a delicate operation that must be done manually. Therefore, the foldable grill described in Patent Document 1 poses a risk of burns or injuries.

[0005] Furthermore, after use, the barbecue grill often accumulates a large amount of ash, especially on the walls around the charcoal storage area. Therefore, during the process of folding the barbecue grill described in Patent Document 1, the user's hands or clothing can easily become soiled.

[0006] As mentioned above, existing foldable barbecue grills are not convenient to open and close. Therefore, the object of the present invention is to provide a foldable barbecue grill that is easier to open and close. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a foldable barbecue grill that can be easily switched between an unfolded state and a folded state.

[0008] The present invention provides a foldable barbecue grill, comprising a first main panel and a second main panel arranged opposite to each other, and a first side panel and a second side panel arranged opposite to each other in the unfolded state.

[0009] Both the first main panel and the second main panel are rectangular in shape; the two pairs of opposite ends of the first main panel are the first main edge and the second main edge, as well as the first side edge and the second side edge; the two pairs of opposite ends of the second main panel are the third main edge and the fourth main edge, as well as the third side edge and the fourth side edge; the first main edge and the third main edge are opposite to each other, and the first side edge and the third side edge are opposite to each other; the first main edge and the third main edge are rotatably connected directly or indirectly through other components.

[0010] Both the first and second side panels are triangular in shape.

[0012] The first side panel includes a first sub-panel and a third sub-panel; the second side panel includes a second sub-panel and a fourth sub-panel; the first sub-panel and the third sub-panel are rotatably connected; the second sub-panel and the fourth sub-panel are rotatably connected.

[0013] As a further improvement of this utility model, in the unfolded state, the surface containing the first side and the third side is defined as the first side surface, and the surface containing the second side and the fourth side is defined as the second side surface;

[0014] The first side is covered by the first side panel, and the second side is covered by the second side panel.

[0015] As a further improvement of this utility model, in the unfolded state, the first sub-panel and the third sub-panel are installed and connected and located on the same plane; the second sub-panel and the fourth sub-panel are installed and connected and located on the same plane.

[0016] As a further improvement of this utility model, in the folded state, the first main panel, the first sub-panel, the third sub-panel, and the second main panel overlap each other; the first main panel, the second sub-panel, the fourth sub-panel, and the second main panel overlap each other.

[0017] As a further improvement of this utility model, in the folded state, the outer surfaces of the first sub-panel and the third sub-panel are arranged opposite to each other, and the outer surfaces of the second sub-panel and the fourth sub-panel are arranged opposite to each other.

[0018] As a further improvement of this utility model, it is arranged in a cuboid shape when folded and in a triangular prism shape when unfolded.

[0019] As a further improvement of this utility model, the first main panel includes sidewall portions extending along the first side and the second side respectively; the second main panel includes sidewall portions extending along the third side and the fourth side respectively; the first main side and the third main side are connected to each other through the corresponding sidewall portions.

[0020] As a further improvement of this utility model, the first side panel is connected to the first side and the third side through corresponding side wall portions; the second side panel is connected to the second side and the fourth side through corresponding side wall portions.

[0021] As a further improvement of this utility model, it also includes a sliding net; in the unfolded state, the sliding net is directly or indirectly disposed between the second main side and the fourth main side through other components;

[0022] The first and second main panels are equipped with guide rails;

[0023] The sliding net includes a guide rail receiving part that fits into the guide rail.

[0024] As a further improvement of this utility model, at least one of the first main panel and the second main panel is provided with a plurality of first openings; a sliding component is provided on the main panel with the first openings; the sliding component is movably provided on the first main panel or the second main panel with the first openings; and a plurality of second openings are provided on the sliding component.

[0025] As a further improvement of this utility model, the first main panel includes a first lower extension extending along the first main side; the second main panel includes a second lower extension extending along the third main side.

[0026] In the folded state, a gap is formed between the first lower extension and the second lower extension;

[0027] In the unfolded state, the first lower extension and the second lower extension abut against each other.

[0028] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0029] The barbecue grill can switch between an unfolded and a folded state thanks to its structure consisting of a main panel and side panels.

[0030] By unfolding the grill from its folded state to its unfolded state, the sides of the grill can be covered by its own components, namely the side panels; therefore, there is no need to carry additional components for covering the sides; in addition, when unfolded, the sides are covered, which helps to regulate the burning of the charcoal and also prevents ash from being scattered by the wind.

[0031] In the unfolded state, the two sub-panels are basically unfolded at 180 degrees, which can enhance the structural strength of the barbecue grill in the unfolded state.

[0032] In the folded state, the main panel and the sub-panel overlap each other; therefore, the grill can be folded without increasing the overall size; the outer sides of the sub-panels are arranged opposite each other; by folding the sides of the grill so that the outer sides face each other, the increase in the overall size of the grill due to folding can be easily suppressed.

[0033] When unfolded, the grill is approximately triangular prism-shaped; therefore, it is easier to form a structure that can efficiently transfer the heat from the charcoal to the food; in addition, when folded, it is approximately cuboid-shaped, making it easier to store the grill.

[0034] The two main sides are connected to each other through the side walls; therefore, when unfolded, the bottom of the grill is more likely to be wide in the horizontal direction, making it easier to leave space for placing heat sources such as charcoal.

[0035] The side panels are connected to each side via sidewalls; therefore, it is easier to leave space between the two main panels when folded, which makes it easier to store parts that are removed during folding (such as sliding mesh).

[0036] The sliding mesh is mounted on the main panel via guide rails; therefore, the heat transferred to the food can be easily adjusted by sliding the mesh.

[0037] When unfolded, the bottom of the grill is covered; when folded, the bottom is open. Therefore, it is easier to empty the charcoal ash when cleaning the grill after use.

[0038] The second opening of the sliding component corresponds to the first opening on the main panel, meaning that the following states can be achieved through the relative positional relationship between the sliding component and the main panel:

[0039] Fully open state: The first opening is completely overlapped with the second opening, so that the first opening is not blocked by the sliding part;

[0040] Completely blocked state: The first opening is completely overlapped with the sliding shielding part where the sliding component has no opening, so the first opening is completely blocked by the sliding component.

[0041] Partially blocked state: A portion of the first opening coincides with the sliding shielding part where the sliding component does not have an opening, so that a portion of the first opening is blocked by the sliding component;

[0042] By switching between fully open, fully closed, and partially closed states, and adjusting the proportion of the first opening blocked by the sliding component in the partially closed state, the firepower can be adjusted by regulating the air volume. Attached Figure Description

[0054] The present invention will be further described in detail below with reference to the embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0055] Specific Implementation Example 1: Please refer to Figures 1-8 A foldable barbecue grill,

[0056] like Figure 1 As shown, the barbecue grill 1 of this embodiment is nearly triangular prism-shaped when unfolded. Figure 2 As shown, it is close to a cuboid shape when folded.

[0057] like Figure 1 The bidirectional arrows shown represent the width direction 101, the depth direction 102, and the height direction 103, respectively; these directions are orthogonal to each other.

[0058] The depth direction 102 is the direction in which the dimensions of the barbecue grill 1 change between its folded and unfolded states; the height direction 103 is the direction perpendicular to the barbecue grill 1 when it is in use; the width direction 101 is the direction orthogonal to the depth direction 102 and the height direction 103; these directions are... Figure 1 The same direction is also indicated in the other accompanying figures; in the direction parallel to the height direction 103, such as Figure 1 As shown, the direction indicated by arrow 1031 is defined as the downward direction 1031, and the direction indicated by arrow 1032 is defined as the upward direction 1032; furthermore, in the barbecue grill 1, Figure 1 The part indicated by the middle arrow 1031 is called the lower part 1131, and the part indicated by the arrow 1032 is called the upper part 1132.

[0059] like Figure 1 As shown, the barbecue grill 1 includes a first main panel 11, a second main panel 12, a first side panel 31, and a second side panel 32;

[0060] The first main panel 11, the second main panel 12, the first side panel 31, and the second side panel 32 are all plate-shaped components made of metal.

[0061] The first main panel 11, the second main panel 12, the first side panel 31, and the second side panel 32 are rotatably connected to each other via externally provided connecting parts, etc.

[0062] The internal cavity formed by the first main panel 11, the second main panel 12, the first side panel 31, and the second side panel 32 is called the inner cavity 3.

[0063] Both the first main panel 11 and the second main panel 12 are plate-shaped components that are close to cuboids; the first main panel 11 and the second main panel 12 are arranged opposite each other in the depth direction 102; the first main panel 11 and the second main panel 12 have basically the same shape.

[0064] The following description of the main panel will be based on the first main panel 11 as an example; unless otherwise specified, the description of the first main panel 11 also applies to the second main panel 12.

[0065] The outer main surface of the first main panel 11; such as Figure 2As shown, the outer main surface of the first main panel 11 has a first outer main surface 111; in the folded state, the first outer main surface 111 is parallel to the width direction 101 and the height direction 103; optionally, the first outer main surface 111 is approximately rectangular.

[0066] Similarly, the second main panel 12 has a second outer main surface 121.

[0067] The inner main surface of the first main panel 11; such as Figure 1 As shown, the reverse side of the first outer main surface 111 of the first main panel 11 is the first inner main surface 112.

[0068] Similarly, the reverse side of the second outer main surface 121 of the second main panel 12 is the second inner main surface 122.

[0069] The first inner main surface 112 and the second inner main surface 122 both face the interior space 3 of the barbecue oven 1 and are arranged opposite to each other.

[0070] The first main panel 11 and the second main panel 12 are collectively referred to as the main panels; the main edges and side edges of the main panels are described below:

[0071] like Figure 1 As shown, on the first outer main surface 111 and the first inner main surface 112, among the upper and lower edges parallel to the width direction 101, the edge located below the height direction 103 (i.e., downward direction 1031) is called the first main edge 131; while the edge located above the height direction 103 (i.e., upward direction 1032) is called the second main edge 132.

[0072] Furthermore, on the first outer main surface 111 and the first inner main surface 112, among a pair of edges parallel to the height direction 103, one edge is referred to as the first side edge 141 and the other edge is referred to as the second side edge 142.

[0073] The second main panel 12 is the same as the first main panel 11; the main edge and side edge of the second outer main surface 121 and the second inner main surface 122 are respectively referred to as the third main edge 133, the fourth main edge 134, the third side edge 143 and the fourth side edge 144.

[0074] The main panel includes a side wall portion; the side wall portion refers to the portion extending from the side edge of the main panel along the depth direction 102; the first main panel 11 and the second main panel 12 each include two side wall portions.

[0075] like Figure 1 and Figure 2As shown, the sidewall portion extending from the first side 141 is the first sidewall portion 151, the sidewall portion extending from the second side 142 is the second sidewall portion 152, the sidewall portion extending from the third side 143 is the third sidewall portion 153, and the sidewall portion extending from the fourth side 144 is the fourth sidewall portion 154.

[0076] The following description uses the first sidewall portion 151 as an example to illustrate the sidewall portion; the first sidewall portion 151 extends a certain length from the first side 141 in the depth direction 102; the first sidewall portion 151 is approximately rectangular in shape, and its long side extends along the first side 141.

[0077] The first sidewall portion 151 has an end edge that is substantially parallel to the first side edge 141, and this end edge is the side edge of the sidewall portion; specifically, the side edge of the first sidewall portion 151 is the first sidewall portion side edge 161; the side edge of the second sidewall portion 152 is the second sidewall portion side edge 162; the side edge of the third sidewall portion 153 is the third sidewall portion side edge 163; and the side edge of the fourth sidewall portion 154 is the fourth sidewall portion side edge 164.

[0078] The first sidewall portion 151 has an end edge connected to the first main edge 131, which is called the first sidewall portion main edge 171; similarly, the end edge of the second sidewall portion 152 connected to the first main edge 131 is called the second sidewall portion main edge 172; the end edge of the third sidewall portion 153 connected to the third main edge 133 is called the third sidewall portion main edge 173; and the end edge of the fourth sidewall portion 154 connected to the third main edge 133 is called the fourth sidewall portion main edge 174.

[0079] The first main panel 11 and the second main panel 12 are connected by the first main edge 131 of the first main panel 11 and the third main edge 133 of the second main panel 12.

[0080] The portion of the first main panel 11 near the first main edge 131 is called the first main edge portion 181; the first main edge portion 181 includes the adjacent portion of the first side wall portion main edge 171 connected to the first main edge 131 and the adjacent portion of the second side wall portion main edge 172 connected to the first main edge 131.

[0081] Similarly, the portion of the second main panel 12 near the third main edge 133 is called the second main edge portion 182; the second main edge portion 182 includes the adjacent portion of the third side wall main edge 173 connected to the third main edge 133 and the adjacent portion of the fourth side wall main edge 174 connected to the fourth main edge 134.

[0082] The first main panel 11 and the second main panel 12 are connected by the first main edge 131 side and the third main edge 133 side, that is, the first main edge portion 181 of the first main panel 11 and the second main edge portion 182 of the second main panel 12 are connected to each other.

[0083] The barbecue grill 1 also includes a connecting part 200; the connection between the first main panel 11 and the second main panel 12 is achieved through the connecting part 200.

[0084] Regarding the connecting part 200, see Figure 1 , Figure 2 as well as Figure 3 Provide an explanation; Figure 3 yes Figure 1 Enlarged view of the circled area marked 90; the first main panel 11 and the second main panel 12 are rotatably connected by a connecting part 200; the connecting part 200 is provided at both ends of the width direction 101 of the main panel.

[0085] The following description takes one end of the connecting part 200 as an example, and the other end is also provided with the same connecting structure; each connecting part 200 includes two rivets, two rivet holes and a central guide 205.

[0086] A rivet hole refers to a through hole formed in the first main panel 11 or the second main panel 12; such as Figure 3 As shown, two rivet holes are respectively provided on the first main panel 11 and the second main panel 12; the one provided on the first main panel 11 is called the first rivet hole 211, and the one provided on the second main panel 12 is called the second rivet hole 212.

[0087] Specifically, rivet holes are located on the side walls of each main panel; such as Figure 3 As shown, the first rivet hole 211 is located near the main edge 171 of the first side wall portion 151, that is, the first rivet hole 211 is located on the first main edge portion 181; the second rivet hole 212 is located near the main edge 173 of the third side wall portion 153, that is, the second rivet hole 212 is located on the second main edge portion 182.

[0088] The central guide 205 is a plate-shaped structure; the central guide 205 is clamped and connected to the corresponding main panel by rivets, and is used to rotatably connect the first main panel 11 and the second main panel 12; the central guide 205 is located at the position corresponding to the rivet hole in the inner cavity 3 of the barbecue oven 1; the central guide 205 spans the first main panel 11 and the second main panel 12 in the depth direction 102, and is installed on the inner side wall of the first main panel 11 and the second main panel 12, that is, in the inner cavity 3 of the barbecue oven 1; specifically, the central guide 205 spans the first side wall portion 151 and the third side wall portion 153, and is located in the inner cavity 3 of the barbecue oven 1 between the first side wall portion 151 and the third side wall portion 153.

[0089] A rivet through hole 206 is provided through the center guide 205. The rivet through hole 206 is a through hole provided in the center guide 205. When the center guide 205 is installed in the inner cavity 3 of the barbecue oven 1, the rivet through hole 206 extends along the depth direction 102.

[0090] The rivets are inserted into the respective rivet holes; such as Figure 1 As shown, it is inserted into the first rivet hole 211 (see...) Figure 3 The rivet in the diagram is the first rivet 201, which is inserted into the second rivet hole 212 (see...). Figure 3 The second rivet 202 is mentioned in the original text. Figure 3 (not shown in the image); the first rivet 201 passes through the first rivet hole 211 and the rivet guide hole 206 of the center guide 205 and is fixed; the second rivet 202 passes through the second rivet hole 212 and the rivet guide hole 206 of the center guide 205 and is fixed.

[0091] In the connecting part 200, the first main panel 11 and the second main panel 12 are fixed together in a rotatable manner by passing through the rivet holes of the corresponding first main panel 11 and second main panel 12 and the rivet through hole 206 of the center guide piece 205 with both ends of the rivet.

[0092] By rotating the first main panel 11 and the second main panel 12 around the connecting part 200, the barbecue grill 1 can switch between a folded state and an unfolded state.

[0093] The following explains how the barbecue grill 1 switches from the folded state to the unfolded state:

[0094] In the unfolded state, the degree of unfolding of the first main panel 11 and the second main panel 12 can be limited by the fact that a portion of the first main panel 11 and a portion of the second main panel 12 abut against each other after the first main panel 11 and the second main panel 12 are unfolded; that is, when a portion of the first main panel 11 abuts against a portion of the second main panel 12, a state in which it cannot be unfolded further will occur, and this state is the unfolded state; as mentioned above, the portion in which the first main panel 11 and the second main panel 12 abut against each other is called the rotation stop end.

[0095] like Figure 3 As shown, a first rotation stop end 191 is provided on the first side wall portion 151; a second rotation stop end 192 is provided on the third side wall portion 153. The first rotation stop end 191 is the rotation stop end on the side of the first main panel 11, and the second rotation stop end 192 is the rotation stop end on the side of the second main panel 12.

[0096] The first rotation stop end 191 is provided at the end of the side wall portion of the first main panel 11 that is opposite to the side wall portion of the second main panel 12; similarly, the second rotation stop end 192 is provided at the end of the side wall portion of the second main panel 12 that is opposite to the side wall portion of the first main panel 11.

[0097] like Figure 3 As shown, the first rotation stop end 191 is disposed on the first side wall portion 151, and the second rotation stop end 192 is disposed on the third side wall portion 153; by the first rotation stop end 191 and the second rotation stop end 192 abutting against each other, the unfolding of the first main panel 11 and the second main panel 12 can be restricted.

[0098] In the unfolded state, the extension directions of both the first rotation stop end 191 and the second rotation stop end 192 are along the height direction 103; for example Figure 1 As shown, in the unfolded state, the angle between the first side 141 and the third side 143 is defined as angle 92.

[0099] Optionally, the angle 92 can be set to, for example, above 30 degrees or below 90 degrees.

[0100] like Figure 1 As shown, in the unfolded state, the component constituting the side portion of the width direction 101 of the barbecue grill 1 is called a side panel; the side panel includes a first side panel 31 and a second side panel 32; one side of the two sides of the barbecue grill 1 is defined as the first side panel 5 and the other side is defined as the second side panel 6; the first side panel 31 is the side panel constituting the first side panel 5; the second side panel 32 is the side panel constituting the second side panel 6.

[0101] In this embodiment, the side of the barbecue grill 1 is mainly composed of the side wall portion of the main panel and the side panel; specifically, the first side 5 is composed of the first side wall portion 151, the third side wall portion 153 and the first side panel 31; similarly, the second side 6 is composed of the second side wall portion 152, the fourth side wall portion 154 and the second side panel 32.

[0102] The sides of the barbecue grill 1 are approximately triangular in shape; correspondingly, the side panel is also approximately triangular in shape.

[0103] Each side panel contains multiple sub-panels; specifically, the first side panel 31 contains a first sub-panel 301 and a third sub-panel 303; the second side panel 32 contains a second sub-panel 302 and a fourth sub-panel 304; the following will mainly use the first side panel 5 as an example to explain the matters concerning the sub-panels; the matters explained below also apply to the second side panel 6.

[0104] The first sub-panel 301 and the third sub-panel 303 constitute the first side panel 31. The first sub-panel 301 and the third sub-panel 303 are formed by dividing the first side panel 31 into two parts along the height direction 103.

[0105] Two sub-panels forming the same side panel are rotatably connected by a hinge; the hinge connecting the first sub-panel 301 and the third sub-panel 303 is called the first hinge; the hinge connecting the second sub-panel 302 and the fourth sub-panel 304 is called the second hinge.

[0106] like Figure 1 and Figure 4 As shown, in the unfolded state, the two sub-panels are roughly on the same plane; in other words, the included angle between the two sub-panels is close to 180 degrees; when the barbecue grill 1 is folded from the unfolded state to the folded state, as... Figure 5 As shown, the hinge moves toward the inner cavity 3 of the barbecue grill 1; thereby, by folding the two sub-panels connected by the hinge, the included angle between the two sub-panels gradually approaches 0 degrees, achieving the purpose of folding.

[0107] The sub-panel and the main panel are rotatably connected by hinges; specifically, the sidewalls of the sub-panel and the main panel are connected by hinges; the hinge connecting the sub-panel and the main panel is called the main hinge.

[0108] like Figure 1 As shown, the main hinge connecting the first sub-panel 301 and the first side wall portion 151 is called the first main hinge 321; similarly, the main hinge connecting the second sub-panel 302 and the second side wall portion 152 is called the second main hinge 322, the main hinge connecting the third sub-panel 303 and the third side wall portion 153 is called the third main hinge 323, and the main hinge connecting the fourth sub-panel 304 and the fourth side wall portion 154 is called the fourth main hinge 324.

[0109] The main hinge is configured to extend along the side it is connected to; taking the first main hinge 321 as an example, the first main hinge 321 extends along the direction of the first side 141; the first side 141 is the edge of the end of the first side wall portion 151 connected by the first main hinge 321.

[0110] like Figure 1 and Figure 4As shown, in the unfolded state, the sub-panel and the side wall portion connected to the sub-panel are approximately on the same plane; in other words, the angle between the sub-panel and the side wall portion is close to 180 degrees; in addition, as mentioned above, in the unfolded state, the angle between the two sub-panels is also close to 180 degrees; thus, in the unfolded state, the two sub-panels constituting one side and the two side wall portions are approximately on the same plane; taking the first side 5 as an example, the first side wall portion 151, the first sub-panel 301, the third sub-panel 303 and the third side wall portion 153 are approximately on the same plane.

[0111] When the barbecue grill 1 is folded from the unfolded state to the folded state, as follows: Figure 5 As shown, two main hinges on the same side move towards each other along the depth direction 102; as the two main hinges move, the sub-panel rotates and moves towards the inner cavity 3 of the barbecue oven 1 with the corresponding main hinge as the axis of rotation; in the folded state, the two sub-panels contained in the same side are close to each other, and their included angle is close to 0 degrees; in the folded state, the dimensions in the depth direction 102 of the barbecue oven 1 are basically the same as the dimensions in the height direction 103; in other words, the shape of the barbecue oven 1 is roughly cuboid.

[0112] More specifically, in the folded state, the first main panel 11, the first sub-panel 301, the third sub-panel 303, and the second main panel 12 overlap each other; the first main panel 11, the second sub-panel 302, the fourth sub-panel 304, and the second main panel 12 also overlap each other; in addition, in the folded state, the outer surfaces of the first sub-panel 301 and the third sub-panel 303 face each other, and the outer surfaces of the second sub-panel 302 and the fourth sub-panel 304 also face each other; the term "outer surface" here refers to the surface opposite to the surface of the inner cavity 3 facing the grill oven 1 in the unfolded state.

[0113] When switching from an unfolded state to a folded state, for example, the first main panel 11 and the second main panel 12 abut against each other in the height direction 103, thereby switching from an unfolded state to a folded state.

[0114] As described above, the barbecue grill 1 shown in this embodiment can be unfolded and folded simply by opening and closing the main panel, providing a foldable barbecue grill with a simple structure; furthermore, the barbecue grill 1 of this embodiment can cover both sides in the unfolded state without special operation, thereby realizing a fully functional foldable barbecue grill.

[0115] like Figure 1As shown, the barbecue grill 1 includes a fixing component 70; the fixing component 70 is a component used to prevent the barbecue grill 1 from being accidentally folded in the unfolded state; the first side 5 and the second side 6 are respectively provided with corresponding fixing components 70; the following description takes the fixing component 70 provided on the first side 5 as an example, and the fixing component 70 provided on the second side 6 can also adopt the same structure.

[0116] The fixing component 70 includes a fixing arm component 71 and a fixing arm receiving component 72; the fixing arm component 71 is an elongated component used to limit the depth direction 102 dimension of the barbecue grill 1 in the unfolded state; the fixing arm component 71 is disposed on the upper part 1132 of the third side wall portion 153; the fixing arm receiving component 72 is a component used to fix one end of the fixing arm component 71, and it is disposed on the upper part 1132 of the first side wall portion 151.

[0117] The fixed arm component 71 includes an extension 711, a rotating part 712, and an inserting part 713; the extension 711 is an elongated component, and the length of the extension 711 corresponds to the length dimension of the depth direction 102 between the third side wall portion 153 and the first side wall portion 151 in the unfolded state; the rotating part 712 is a component that rotatably fixes one end of the extension 711 to the third side wall portion 153;

[0118] The fixed arm receiving component 72 includes a fitting hole 721; the insert portion 713 is disposed at the other end of the extension portion 711, and the other end of the extension portion 711 is fixed to the arm receiving component 72 by fitting into the fitting hole 721 disposed in the fixed arm receiving component 72; the fitting hole 721 is used to fit into the insert portion 713 of the fixed arm component 71, thereby realizing connection and fixation.

[0119] By inserting the insert 713 into the fitting hole 721 and fixing the fixing arm component 71 to the fixing arm receiving part 72, the size of the grill 1 in the depth direction 102 can be fixed; therefore, the grill 1 can be prevented from being accidentally folded in the unfolded state.

[0120] It should be noted that the fixing component 70 is not limited to being provided on both the first side 5 and the second side 6 at the same time, but may also be provided on only one of the first side 5 or the second side 6.

[0121] like Figure 6 As shown, one of the usage states of the barbecue grill 1; Figure 6 A schematic diagram showing the barbecue grill 1 installed on an externally mounted frame 1000; as shown. Figure 5 and Figure 6 As shown, the barbecue grill 1 has a handle 7; in addition, as Figure 1As shown, a handle recess 8 is formed between the handle 7 and the main panel; therefore, by inserting the tube 1001 provided on the frame 1000 into the handle recess 8 of the grill 1, the grill 1 can be easily and securely installed on the frame 1000.

[0122] like Figure 7 As shown, the barbecue grill 1 is equipped with a charcoal mesh component 80; Figure 7 This is a perspective view of the barbecue grill 1 from above; the charcoal mesh component 80 is a plate-shaped component used to support heat sources such as charcoal, and is installed in the inner cavity 3 of the barbecue grill 1 when the barbecue grill 1 is in use; the charcoal mesh component 80 has a plate-shaped structure with multiple continuously formed slender openings; these openings are called charcoal mesh openings 82; in addition, when the barbecue grill 1 is not in use, the charcoal mesh component 80 can also be stored between the first main panel 11 and the second main panel 12 in a folded state.

[0123] like Figure 6 and Figure 7 As shown, the barbecue grill 1 is equipped with a sliding mesh 40; the sliding mesh 40 is a plate-shaped component for placing food or pots and other heating items, and is set on the upper part 1132 of the barbecue grill 1; the sliding mesh 40 has a plate-shaped structure with multiple continuously formed elongated openings, which are called mesh holes 41; in addition, when the barbecue grill 1 is not in use, the sliding mesh 40 can also be stored between the first main panel 11 and the second main panel 12 in a folded state, just like the charcoal mesh component 80.

[0124] like Figure 7 As shown, the sliding net 40 has guide rail receiving parts 42 on both sides of the depth direction 102 and along the width direction 101; the structure of the guide rail receiving part 42 is that the end of the sliding net 40 is bent into a shape with a concave part.

[0125] like Figure 7 and Figure 1 As shown, a guide rail 43 is formed on the main edge of the main panel; specifically, guide rails 43 are respectively provided on the second main edge 132 of the first main panel 11 and the fourth main edge 134 of the second main panel 12.

[0126] The sliding net 40 can slide while food or cookware is placed on it; the sliding function can be achieved, for example, by interlocking the guide rail on the main panel with the guide rail receiving part on the sliding net 40.

[0127] It should be noted that the guide rail 43 is located on the main edge, not just directly on the main edge; it should also be included even if the guide rail 43 is indirectly located on the main edge through, for example, an extension connected to the main edge. Figure 1 In the example shown, the guide rail 43 is provided on the upper side via an upper side extension.

[0128] like Figure 1 As shown, the first main panel 11 includes a first upper extension 431; the first upper extension 431 extends from the second main side 132 in a direction opposite to the first main side 131; similarly, the second main panel 12 includes a second upper extension 432; the second upper extension 432 extends from the fourth main side 134 in a direction opposite to the third main side 133; guide rails 43 are respectively disposed on the end edges of the first upper extension 431 and the second main side 132 opposite to each other, and on the end edges of the second upper extension 432 and the fourth main side 134 opposite to each other.

[0129] The guide rail 43, for example, is machined from the end of the main panel into a shape that can fit into the guide rail receiving portion 42 of the sliding mesh 40; in addition, the guide rail 43 extends along the width direction 101; in Figure 7 and Figure 1 In the example shown, the guide rail 43 is a structure in which the end of the main panel is bent outward.

[0130] exist Figure 1 In the example shown, in the unfolded state, the first upper extension 431 and the second upper extension 432 extend along the height direction 103; the guide rail 43 extends from each upper extension toward the outside of the grill 1 along the depth direction 102.

[0131] It should be noted that the shapes of the guide rail receiving part 42 and the guide rail 43 are not limited to the above examples; as long as the guide rail receiving part 42 and the guide rail 43 can fit together and make the sliding net 40 slide, its structure is not particularly limited.

[0132] The barbecue grill 1 of this embodiment is equipped with a sliding mesh 40, which makes it easy to remove food from the fire source and add charcoal. In addition, there is no particular limitation on the number of sliding meshes 40 provided with the barbecue grill 1. For example, one sliding mesh 40 can be used to cover the upper part 1132 of the barbecue grill 1, or multiple sliding meshes 40 can be used to cover the upper part 1132.

[0133] like Figure 4 and Figure 5 As shown, the lower part 1131 of the barbecue grill 1, that is, the bottom of the barbecue grill 1; as Figure 4 As shown, when the barbecue grill 1 is in use (i.e., in the unfolded state), its lower part 1131 is in the closed state; therefore, it can prevent charcoal from falling from the lower part 1131 during grilling.

[0134] In contrast, when the barbecue grill 1 is finished using and in the folded state, such as Figure 5As shown, its lower part 1131 is in the open state; therefore, when the barbecue is finished and the charcoal needs to be disposed of, there is no need to flip the barbecue grill 1 or manually remove the charcoal ash inside. You can simply close (i.e. fold) the barbecue grill 1 at the charcoal disposal area to directly dispose of the charcoal or ash. The operation is simple.

[0135] Specifically, such as Figure 4 As shown, the first main panel 11 includes a first lower edge extension 501; the first lower edge extension 501 extends from the first main edge 131 in the opposite direction to the second main edge 132; similarly, the second main panel 12 includes a second lower edge extension 502; the second lower edge extension 502 extends from the third main edge 133 in the opposite direction to the fourth main edge 134; in the first lower edge extension 501, the end edge opposite to the first main edge 131 is called the first bottom edge 511; similarly, in the second lower edge extension 502, the end edge opposite to the third main edge 133 is called the second bottom edge 512.

[0136] In the unfolded state, such as Figure 4 As shown, the first bottom edge 511 and the second bottom edge 512 abut against each other; thus, as indicated by arrow 551, the lower part 1131 of the barbecue grill 1 is in a closed state; therefore, during the use of the barbecue grill 1, it is possible to prevent charcoal from falling from the lower part 1131.

[0137] On the other hand, in the folded state, such as Figure 5 As shown, the first bottom edge 511 and the second bottom edge 512 no longer abut against each other, and a gap is formed between them; that is, as shown by arrow 552, the lower part 1131 of the barbecue grill 1 is in the open state; therefore, when discarding charcoal, simply set the barbecue grill 1 to the folded state, and you can easily discard charcoal or ash from the lower part 1131.

[0138] like Figure 8 As shown, the barbecue grill 1 of this embodiment adjusts the amount of air entering the oven body by opening or closing the vent provided in the lower part 1131, thereby adjusting the heat. Figure 8 A perspective view of the barbecue grill 1 from depth direction 102.

[0139] The barbecue grill 1 is provided with an air conditioning unit 60 for regulating the amount of air. The air conditioning unit 60 includes: a slit 62 provided on the main panel, a sliding member 66 that can slide at a position corresponding to the slit 62 on the surface of the main panel, and a guide 64 for limiting the sliding position of the sliding member 66. The following description uses the first main panel 11 as an example. It should be noted that the second main panel 12 is also provided with an air conditioning unit 60 with the same structure as described below.

[0140] The slit portion 62 is disposed near the lower part 1131 of the first main panel 11 along the width direction 101; specifically, the slit portion 62 is disposed near the first main edge 131 and extends along the width direction 101; the slit portion 62 includes a plurality of slit openings 621 and a plurality of slit shielding portions 622; the slit openings 621 are through holes formed in the first main panel 11, through which air can enter and exit the interior of the barbecue oven 1; the slit openings 621 can be cuboids that are longer in the height direction 103, and a plurality of them are provided along the width direction 101; the slit openings 621 are also called the first opening, to distinguish them from the sliding opening 661 (second opening) described later; the portion between adjacent slit openings 621 is called the slit shielding portion 622.

[0141] The sliding member 66 is disposed on the outer side of the first main panel 11, corresponding to the slot 62; the sliding member 66 can slide along the slot 62 in the width direction 101; the sliding member 66 slides within a range defined by a guide portion 64 provided on the first main panel 11; the guide portion 64 may be a frame covering at least a portion of the end of the sliding member 66; Figure 8 In the embodiment shown, the guide portion 64 is disposed on the upper and lower sides of the slit portion 62 and extends along the width direction 101.

[0142] An opening and a shielding portion are provided on the sliding component 66 at positions corresponding to the slit opening 621 and the slit shielding portion 622 of the slit portion 62. The opening is a through hole that passes through the sliding component 66. The opening provided on the sliding component 66 is called a sliding opening 661. Multiple sliding openings 661 are arranged consecutively. Relative to the first opening (i.e., the slit opening 621), the sliding opening 661 can also be called the second opening. The shielding portion refers to the portion between adjacent sliding openings 661, and this shielding portion is called a sliding shielding portion 662. The sliding shielding portion 662 can also be understood as the area on the sliding component 66 where no sliding opening 661 is formed.

[0143] The sliding opening 661 and sliding shielding part 662 of the sliding member 66 correspond to the opening opening 621 and opening shielding part 622 of the opening part 62. This means that the following states can be achieved through the relative positional relationship between the sliding member 66 and the opening part 62:

[0144] Fully open state: The slit opening 621 is completely overlapped with the sliding opening 661, so that the slit opening 621 is not blocked by the sliding component 66.

[0145] Completely closed state: The opening 621 is completely overlapped with the sliding shielding part 662, so that the opening 621 is completely blocked by the sliding part 662.

[0146] Partially closed state: A portion of the slit opening 621 coincides with the sliding shielding part 662, so that a portion of the slit opening 621 is blocked by the sliding member 66.

[0147] The firepower can be adjusted by regulating the air volume, which can be achieved by switching between fully open, fully closed, and partially closed states, as well as by adjusting the proportion of the opening 621 that is blocked by the sliding component 66 in the partially closed state.

[0148] like Figure 1 As shown, in the barbecue grill 1 of this embodiment, the first side 5 is covered by the first side panel 31, and the second side 6 is covered by the second side panel 32, etc. Therefore, apart from the inflow from the upper part 1132, air enters the inner cavity 3 of the barbecue grill 1 only through the opening 62. Therefore, by adjusting the opening state of the opening 62 by the sliding member 66, the heat of the charcoal can be easily and accurately adjusted.

[0149] It should be noted that the air conditioning unit 60 is not limited to being installed on both the first main panel 11 and the second main panel 12; the air conditioning unit 60 may also be installed on only one of the first main panel 11 and the second main panel 12.

[0150] The barbecue grill includes: a first main panel and a second main panel arranged opposite to each other, and a first side panel and a second side panel arranged opposite to each other in the unfolded state; wherein:

[0151] The first main panel and the second main panel are arranged in an approximately cuboid shape. The two sets of opposite end edges of the first main panel are the first main edge and the second main edge, and the first side edge and the second side edge, respectively. The two sets of opposite end edges of the second main panel are the third main edge and the fourth main edge, and the third side edge and the fourth side edge, respectively.

[0152] The first main edge and the third main edge are arranged opposite to each other, and the first side edge and the third side edge are arranged opposite to each other. The first main edge and the third main edge are directly connected or indirectly rotatably connected through other components.

[0153] The first side panel and the second side panel are arranged in an approximately triangular shape;

[0154] One end of the first side panel is rotatably connected to the first side directly or indirectly through other components, and the other end of the first side panel is rotatably connected to the third side directly or indirectly through other components.

[0155] One end of the second side panel is rotatably connected to the second side directly or indirectly through other components, and the other end of the second side panel is rotatably connected to the fourth side directly or indirectly through other components.

[0156] The first side panel includes a first sub-panel and a third sub-panel, and the second side panel includes a second sub-panel and a fourth sub-panel. The first sub-panel and the third sub-panel are rotatably connected, and the second sub-panel and the fourth sub-panel are rotatably connected.

[0157] The aforementioned barbecue grill provides an easy-to-open and close folding design.

[0158] In the unfolded state, when the surface containing the first side and the third side is defined as the first side surface, and the surface containing the second side and the fourth side is defined as the second side surface, the first side surface is covered by the first side panel, and the second side surface is covered by the second side panel.

[0159] In the aforementioned barbecue grill, by unfolding the grill from its folded state to its unfolded state, the two sides of the grill can be covered by its own components; therefore, there is no need to carry additional components for covering the sides; in addition, in the unfolded state, the sides are covered, which helps to regulate the burning state of the charcoal fire and also prevents ash from being scattered by the wind.

[0160] In the unfolded state, the first sub-panel is installed and connected to the third sub-panel and is located approximately on the same plane, and the second sub-panel is continuously connected to the fourth sub-panel and is located approximately on the same plane.

[0161] In the aforementioned barbecue grill, when unfolded, the two sub-panels are essentially unfolded at 180 degrees, thereby enhancing the structural strength of the barbecue grill in the unfolded state.

[0162] In the folded state, the first main panel, the first sub-panel, the third sub-panel, and the second main panel overlap each other, as do the first main panel, the second sub-panel, the fourth sub-panel, and the second main panel.

[0163] In the above-mentioned barbecue grill, the main panel and the sub-panel overlap each other in the folded state; therefore, the barbecue grill can be folded without increasing the overall size.

[0164] In the above-mentioned barbecue grill, in the folded state, the outer surfaces of the first sub-panel and the third sub-panel are arranged opposite each other, and the outer surfaces of the second sub-panel and the fourth sub-panel are arranged opposite each other.

[0165] In the above-mentioned barbecue grill, the outer sides of the sub-panels are arranged opposite each other in the folded state; by folding the sides of the barbecue grill so that the outer sides are opposite each other, the increase in the external size of the barbecue grill due to folding can be easily suppressed.

[0166] In the aforementioned barbecue grill, it is approximately rectangular in shape when folded and approximately triangular prism in shape when unfolded.

[0167] In the above-mentioned barbecue grill, the grill is approximately triangular prism-shaped when unfolded; therefore, it is easier to form a structure that can efficiently conduct the heat of the charcoal to the food; in addition, it is approximately cuboid-shaped when folded, which makes it easier to store the barbecue grill.

[0168] In the aforementioned barbecue grill, the first main panel includes sidewall portions extending along a first side and a second side respectively; the second main panel includes sidewall portions extending along a third side and a fourth side respectively; the first main side and the third main side are connected to each other through corresponding sidewall portions.

[0169] In the aforementioned barbecue grill, the two main sides are connected to each other through the side walls; therefore, when unfolded, the bottom of the barbecue grill is more likely to be wide in the horizontal direction, thus making it easier to leave space for placing heat sources such as charcoal.

[0170] In the aforementioned barbecue grill, the first side panel is connected to the first side and the third side via corresponding side wall portions; the second side panel is connected to the second side and the fourth side via corresponding side wall portions.

[0171] In the aforementioned barbecue grill, the side panels are connected to each side via the side wall portion; therefore, in the folded state, it is easier to leave space between the two main panels, thereby making it easier to leave storage space for components (such as sliding mesh) that are disassembled during folding.

[0172] In the above-mentioned barbecue grill, the barbecue grill also includes a sliding mesh. In the unfolded state, the sliding mesh is directly or indirectly disposed between the second main side and the fourth main side through other components. The first main panel and the second main panel are provided with guide rails, and the sliding mesh includes a guide rail receiving part that fits into the guide rail.

[0173] In the aforementioned barbecue grill, the sliding mesh is mounted on the main panel via guide rails; therefore, by sliding the mesh, the heat transferred to the food can be easily adjusted.

[0174] In the aforementioned barbecue grill, at least one of the first main panel and the second main panel has a first opening; the barbecue grill also includes a sliding component, which has a second opening; the sliding component is movably disposed on the first main panel or the second main panel having the first opening.

[0175] In the aforementioned barbecue grill, the degree of obstruction of the main panel opening can be easily adjusted; therefore, the combustion status and temperature of heat sources such as charcoal can be more easily adjusted.

[0176] In the aforementioned barbecue grill, the first main panel includes a first lower extension extending along a first main side; the second main panel includes a second lower extension extending along a third main side.

[0177] In the folded state, a gap is formed between the first lower extension and the second lower extension; in the unfolded state, the first lower extension and the second lower extension abut against each other.

[0178] In the above-mentioned barbecue grill, the bottom of the grill is covered when it is unfolded, and the bottom of the grill is open when it is folded; therefore, it is easier to pour out the charcoal ash when cleaning the grill after use.

[0179] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto; any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and its improved concept, should be covered within the scope of protection of this application.
