Description

Oven cabinet

The present invention relates to an oven cabinet; in particular, to a cabinet that can be disassembled and assembled.

The commonly used oven includes a box and a heater. The box has a baking space inside for placing the objects to be baked. The heater is set in the box to heat the baking space so that the objects to be baked are heated in the baking space.

Take a household oven as an example. Although an oven can bring convenience and fun to baking food, the oven box is composed of multiple plates, which are fixedly connected to each other. Therefore, the shape of the box is fixed and occupies a considerable volume. When the oven needs to be moved, the user usually has to hold the box to move, which makes it inconvenient to move. In addition, when the oven needs to be stored, since the box occupies a considerable volume, the oven requires more storage space to store the box.

Since ovens are inconvenient to move and store, they are usually used and placed in a fixed location indoors at home, and are rarely used outdoors when camping.

Therefore, the design of commonly used ovens is still not perfect and needs to be improved.

In view of this, the purpose of the present invention is to provide a box of an oven that can be disassembled and assembled, and when the box is folded, the panels can be stacked to reduce the volume.

In order to achieve the above-mentioned purpose, the present invention provides a box body of an oven, comprising a base, two first plates and two second plates, wherein the base has two first sides and two second sides, wherein each of the first sides has two first pivoting parts, and each of the second sides has two second pivoting parts; two first axes and two second axes are defined, each of the first axes passes through the two first pivoting parts of each of the first sides, and each of the second axes passes through the two second pivoting parts of each of the second sides; in a height direction of the base, the two first axes and the two second axes are separated from each other; the two first plates respectively have two first hinges, and the two first hinges of each of the first plates are respectively pivoted to the two first pivoting parts of each of the first sides, and each of the first plates can be relatively The base is pivoted between a first folded position and a first assembly position. When each of the first plates is pivoted to the first folded position, the two first plates overlap in the height direction of the base. The two second plates each have two second hinges. The two second hinges of each second plate are respectively pivoted to the two second hinges of each second side. Each of the second plates can be pivoted between a second folded position and a second assembly position relative to the base. When each of the second plates is pivoted to the second folded position, the two second plates overlap in the height direction of the base. When each of the first plates is pivoted to the first assembly position and each of the second plates is pivoted to the second assembly position, the two first plates and the two second plates together enclose a baking space.

Thus, when the box is folded, the two first plates overlap in the height direction of the base by virtue of the four axes being located at different heights, and the two first plates overlap in the height direction of the base, which can effectively reduce the volume of the box and facilitate storage of the box.

In order to explain the present invention more clearly, a preferred embodiment is given and described in detail with drawings. Please refer to Figures 1 to 17, which are a first preferred embodiment of the present invention, an oven 1, comprising a box 10 and a heat source 36. The inside of the box 10 can be used to place the baked object, and the heat source 36 is used to heat the inside of the box 10. The heat source 36 can be, for example, a heater, such as a gas burner or an electric heater, but it is not limited thereto, and charcoal fire can also be used as a heat source. The box 10 includes a base 12, two first plates 28 and two second plates 32.

The base 12 has four side portions, including two first side portions 14 and two second side portions 16. In this embodiment, the two first side portions 14 are located at two opposite sides of the base 12, and the two second side portions 16 are located at the other two opposite sides of the base 12 and between the two first side portions 14. However, the present invention is not limited thereto. Alternatively, one first side portion 14 and one second side portion 16 may be located at two opposite sides of the base 12, and another first side portion 14 and another second side portion 16 may be located at the other two opposite sides of the base 12. Each of the first side portions 14 has two first pivot portions 142 and a blocking portion 144. The two first pivot portions 142 are located below the blocking portion 144. Each of the second side portions 16 has two second pivot portions 162.

In more detail, please refer to FIG. 3 , FIG. 11 and FIG. 12 , the base 12 includes a carrier plate 18, a first support plate 20, a second support plate 22, two first pivot frames 24 and two second pivot frames 26. The carrier plate 18 is a rectangular plate and has four sides, and two opposite sides 184 of the carrier plate 18 respectively constitute the abutment portions 144 of the two first side portions 14. The first support plate 20 and the second support plate 22 are combined with the other two opposite sides of the carrier plate 18. One end of the first support plate 20 has a first pivot hole 202, and the other end has a second pivot hole 204. One end of the second support plate 22 has a first pivot hole 222, and the other end has a second pivot hole 224. The two first pivot holes 202, 222 face each other, the second pivot holes 204, 224 face each other, and in a height direction of the base 12, the positions of the two first pivot holes 202, 222 are higher than the positions of the two second pivot holes 204, 224. One end of the first supporting plate 20 and one end of the second supporting plate 22 form one of the first pivot portions 142, and the other end of the first supporting plate 20 and the other end of the second supporting plate 22 form another first pivot portion 142, thereby, the first supporting plate 20 and the second supporting plate 22 have two first pivot portions 142 located below the carrier plate 18. Two first axes A1a and A1b are defined, one of which passes through the two first pivot holes 202 and 222, and the other first axis A1b passes through the two second pivot holes 204 and 224. In other words, each of the first axes A1a and A1b passes through the two first pivot parts 142 of each of the first side parts 14, and the two first axes A1a and A1b are separated from each other in the height direction of the base 12.

The two first hinge frames 24 and the two second hinge frames 26 are respectively disposed at four corners of the upper surface 182 of the carrier 18. The two first hinge frames 24 are adjacent to the first support plate 20, and the two second hinge frames 26 are adjacent to the second support plate 22. The two first hinge frames 24 are coupled to the upper surface 182 of the carrier 18 and constitute one of the second hinge portions 162. Each of the first hinge frames 24 has a first hinge hole 242, and the two first hinge holes 242 face each other. The two second hinge frames 26 are coupled to the upper surface of the carrier 18 and are located on opposite sides of the two first hinge frames 24. The two second hinge frames 26 constitute another second hinge portion 162. Each of the second pivot frames 26 has a second pivot hole 262, and the two second pivot holes 262 face each other. In the height direction of the base 12, the positions of the two second pivot holes 262 are higher than the positions of the two first pivot holes 242. Thus, the two first pivot frames 24 and the two second pivot frames 26 form two second pivot portions 162 located above the carrier 18. Two second axes A2a and A2b are defined, one of the second axes A2a passes through the first pivot holes 242 of the two first pivot frames 24, and the other second axis A2b passes through the second pivot holes 262 of the two second pivot frames 26. In other words, each of the second axes A2a, A2b passes through the two second pivoting portions 162 of each of the second side portions 16, and in the height direction of the base 12, the two second axes A2a, A2b are separated from each other and from the two first axes A1a, A1b.

In this embodiment, the height of each second hinge frame 26 is higher than the height of each first hinge frame 24. The first support plate 20 has an extension section 206, which extends upward beyond the upper surface 182 of the carrier plate 18 and is located between the two first hinge frames 24 to cover the gap between the two first hinge frames 24. The second support plate 22 has an extension section 226, which extends upward beyond the upper surface 182 of the carrier plate 18 and is located between the two second hinge frames 26 to cover the gap between the two second hinge frames 26. The height of the extension section 226 of the second support plate 22 is higher than the height of the extension section 206 of the first support plate 20.

Please refer to Figures 4 to 9. Each of the first plates 28 has two first hinges 282. The two first hinges 282 of each of the first plates 28 are respectively hinged to the two first hinge portions 142 of each of the first side portions 14, so that each of the first plates 28 can be hinged relative to the base. More specifically, the two first hinges 282 of one of the first plates 28 are respectively hinged to the first hinge holes 202, 222 of the first support plate 20 and the second support plate 22, and the two first hinges 282 of the other first plate 28 are respectively hinged to the second hinge holes 204, 224 of the first support plate 20 and the second support plate 22.

Each of the first plates 28 has a first inner surface 28a, a first outer surface 28b and two side edges 28c. In this embodiment, each of the first plates 28 is a trapezoidal plate, and its side edges 28c are oblique side edges, and the distance between the two side edges 28c gradually decreases from bottom to top. When each of the first plates 28 is pivoted upward to a first assembly position P11, each of the first plates 28 is positioned by leaning against each of the abutting portions 144, that is, each of the first inner surfaces 28a leans against the side edges 184 of the carrier 18. Each of the first plates 28 can be stably positioned by its own weight without the need for support from the user. When the two first plates 28 are both located at the first assembly position P11, the first inner surfaces 28a of the two first plates 28 face each other, and the distance between the two first inner surfaces 28a gradually decreases from bottom to top. By flipping each first plate 28 away from the carrier 18, each first plate 28 can be flipped to a first unfolded position P21 as shown in FIG. 10 .

In one embodiment, each first plate 28 is not limited to being tilted against the abutment portion 144, but can also be positioned by other means, such as magnetic attraction or snap-fit positioning.

As shown in FIG. 1 and FIG. 2 , the first plate 28 located at the front side of the oven 1 has an inlet 28d, and a door panel 30 is pivoted on the first plate 28. When the first plate 28 is pivoted to the first assembly position P11, the door panel 30 can be pivoted between a closed position P0 and an open position P1. As shown in FIG. 1 and FIG. 7 , when the door panel 30 is located at the closed position P0, the door panel 30 leans against the first plate 28 obliquely and closes the inlet 28d. The inlet 28d can be stably closed by the weight of the door panel 30 itself. As shown in FIG. 2 and FIG. 8 , when the door panel 30 is located at the open position P1, the entrance 28d is opened, and an outer surface 302 of the door panel 30 is positioned against the bottom edge of the entrance 28d. At this time, the door panel 30 is supported by the first plate 28 and is higher than the base 12. Thus, when the box 10 is placed on a smaller bearing surface, the door panel 30 can be suspended without being supported by the bearing surface.

Each of the second plates 32 has two second hinges 322, and the two second hinges 322 of each of the second plates 32 are respectively hinged to the two second hinge portions 162 of each of the second side portions 16, so that each of the second plates 32 can be hinged relative to the base 12. More specifically, the two second hinges 322 of one of the second plates 32 are respectively hinged to the two first hinge holes 242 of the first hinge frame 24, and the two second hinges 322 of the other second plate 32 are respectively hinged to the two second hinge holes 262 of the second hinge frame 26.

Each of the second plates 32 has a second inner surface 32a, a second outer surface 32b and two folds 32c. In this embodiment, each of the second plates 32 is a trapezoidal plate, the two folds 32c are located on both sides of each of the second plates, and the distance between the two folds 32c of each of the second plates gradually decreases from bottom to top. As shown in FIGS. 1 and 2 , when each of the first plates 28 pivots to the first assembly position P11 and each of the second plates 32 pivots upward to a second assembly position P12, the two second plates 32 and the two first plates 28 together enclose a baking space S1. In more detail, the two second inner surfaces 32a face each other, and the second inner surface 32a of each second plate 32 is inclined against one of the side edges 28c of the two first plates 28, and the distance between the two second inner surfaces 32a gradually decreases from bottom to top, thereby achieving the purpose of positioning the second plate 32, and the user no longer needs to hold the second plate 32. It is worth mentioning that the folds 32c located on both sides of each second plate 32 are respectively against the first outer surface 28b of the two first plates 28, thereby closing the gap between the adjacent first plates 28 and second plates 32. By flipping each second plate 32 away from the carrier 18, each second plate 32 can be flipped to a second unfolded position P22 as shown in FIG. 10.

In this embodiment, the box 10 further includes a top cover 34. When each of the first plates 28 is pivoted to the first assembly position P11 and each of the second plates 32 is pivoted to the second assembly position P12, the top cover 34 can be detachably mounted on the top of the two first plates 28 and the two second plates 32 to close the top of the baking space S1, and the top cover 34 can limit each of the second plates 32 to the second assembly position P12. In this embodiment, the heat source 36 (heater) of the oven 1 is disposed inside the top cover 34, but this is not limited thereto, and a heat source such as a heater or charcoal fire can also be placed on the carrier 18.

Preferably, the base 12, the two first plates 28, the two second plates 32, the door panel 30 and the top cover 34 are made of metal plates.

The oven 1 of this embodiment further includes a baking net 38, wherein the baking net 38 can be placed on the carrier plate 18, and the object to be baked can be placed on the baking net 38, or the baking net 38 can be removed from the carrier plate 18 and the object to be baked can be directly placed on the carrier plate 18.

As shown in FIG. 10 , when the box 10 is in the unfolded state, the objects to be baked that are larger than the inlet 28d can be placed on the carrier plate 18 or the baking net 38 , and then the two first plates 28 are moved to the first assembly position P11 and the two second plates 32 are moved to the second assembly position P12 , so that the larger objects to be baked can be placed in the baking space S1 .

Please refer to Figures 13 to 17 to explain the steps of folding the box 10. Each of the first plates 28 can be pivoted to a first folded position P31 relative to the base 12, and each of the second plates 32 can be pivoted to a second folded position P32 relative to the base 12.

As shown in FIG. 13 , each second plate 32 can be pivoted to the second folded position P32. Since the two second axes A2a and A2b are separated from each other in the height direction of the base 12, the two second plates 32 can overlap on the carrier 18, that is, one second plate 32 abuts against the upper surface 182 of the carrier 18, and the other second plate 32 abuts against the second outer surface 32b of the second plate 32.

As shown in FIG14, after the base 12 is turned over to face the bottom upward, the first plate 28 is first pivoted to the first folded position P31, at which time the first plate 28 is against the lower surface 186 of the carrier 18, and the first inner surface 28a is opposite to the lower surface 186 of the carrier 18. Referring to FIG15, the grill 38 is placed on the first plate 28. Then, as shown in FIG16, the first plate 28 with the door panel 30 is pivoted to the first folded position P31. Since the two first axes A1a and A1b are spaced apart from each other in the height direction of the base 12, the two first plates 28 can overlap on the carrier 18, that is, Furthermore, a receiving space S2 is formed between the two first plates 28. The receiving space S2 is used to receive the grill 38, but is not limited to receiving the grill 38. In practice, the receiving space S2 can also be formed between the one of the two first plates 28 closest to the carrier 18 and the carrier 18 to receive the grill 38. Of course, the grill 38 can also be moved to another receiving space between the carrier 18 and the one of the two second plates 32 closest to the carrier 18.

As shown in FIG. 17 , after the base 12 is turned over to face downward, each of the first plates 28 is located below the carrier 18, and each of the second plates 32 is located above the carrier 18. This can effectively reduce the volume of the box, making it easier to store or carry. The top cover 34 can be placed on the second plate 32 for storage or carrying.

FIG. 18 shows a box of an alternative embodiment, in which the first pivot frame 24 and the second pivot frame 26 are higher. Therefore, when each of the second plates 32 pivots to the second folded position P32, a receiving space S3 is formed between one of the second plates 32 close to the carrier 18 and the carrier 18. The receiving space S3 can be used to receive the top cover 34, thereby limiting the position of the top cover 34, and the box is more convenient to store and carry. In practice, by increasing the height of the second pivot frame 26, the receiving space S3 can be formed between the two second plates 32 to receive the top cover 34.

FIG. 19 and FIG. 20 show an oven 2 of a second preferred embodiment of the present invention, which is based on the structure of the first embodiment, and further has two supporting structures 40 disposed on the inner side of the top cover 34 , the two supporting structures 40 being located at two opposite sides of the inner side of the top cover 34 . When the top cover 34 is sleeved on the top of the two first plates 28, the top of the two first plates 28 is respectively inserted into a positioning groove 402 of the two supporting structures 40, thereby the two supporting structures 40 respectively abut the top of the two first plates 28, and the top of each first plate 28 is supported by each supporting structure 40, and the lower part is supported by the abutting portion 144 of the base 12, so as to increase the strength of each first plate 28.

FIG. 21 shows an oven 3 of a third preferred embodiment of the present invention, which has a structure substantially the same as that of the first embodiment, except that each of the first plates 44 and each of the second plates 46 of the box body 42 of the present embodiment is a rectangular plate. The folded state of the box body 42 is similar to that of the first embodiment, that is, the two first plates 44 overlap at the bottom of the base 48, and the second plates 46 overlap at the top of the base 48, which will not be described in detail. In addition, each of the first plates 44 is positioned by being upright against the abutment portion of the base 48, but is not limited thereto, and can also be positioned by other means, such as by magnetic attraction or snap-fit positioning. The support structure 40 of the second embodiment can also be provided on the inner side of the top cover 50 of the box body 42 of the present embodiment to support the top of the first plate body 44.

Figures 22 to 29 show an oven 4 of a fourth preferred embodiment of the present invention, which has a structure substantially the same as that of the first embodiment, except that: A gas connector 542 is provided on the rear side of the top cover 54 of the box body 52, and the gas connector 542 is connected to the heater and is provided for connecting to a gas source. Two anti-scalding handles 56 are connected to both sides of the top cover 54, respectively, and the material of the two anti-scalding handles 56 can be an insulating material, such as wood, bakelite, etc., and the anti-scalding handle 70 can be provided for the user to take the top cover 54.

In addition, as shown in FIG. 23 , two grip pads 62 are also provided on both sides of the base 60. The thickness of the two grip pads 62 is greater than the thickness of the plate on both sides of the base 60, so that the user can hold the box 52 with both hands more comfortably.

The top cover 54 has at least two elastic buckles 58 on the inner side, and at least two of the two first plates 64 and the two second plates 66 have at least one buckle hole 642a, 666 on the top. In this embodiment, there are four buckles 58 and they are respectively located near the four corners of the top cover 54. Each of the first plates 64 has a fold 642 on both sides, and each of the folds 642 has a buckle hole 642a on the top, and each of the buckle holes 642a forms an open side at the edge of each of the folds 642. Each of the second plates 66 also has a buckle hole 666 on both sides near each of the folds 662. The first outer surface 64a of each first plate 64 has a concave portion 64b on both sides, and the inner side of each fold 662 of each second plate 66 has a convex portion 664. Each concave portion 64b and each convex portion 664 are formed by stamping.

When each of the first plates 64 is located at the first assembly position P11 and each of the second plates 66 is located at the second assembly position P12, each of the protrusions 664 enters each of the concave portions 64b to form a positioning method in which the concave and convex portions match each other, so that each of the first plates 64 and each of the second plates 66 are not easily moved by external forces. In addition, as shown in FIGS. 25 to 27 , in FIG. 27 , the second plate 66 is partially removed to show the buckle hole 642a. The buckle holes 642a of the folded edges 642 of each of the first plates 64 correspond to the buckle holes 666 of each of the second plates 66, whereby when the top cover 54 is put on the tops of the two first plates 64 and the two second plates 66, the arc surface at the bottom of each of the buckles 58 is elastically deformed along the top edges of each of the second plates 66 and/or the first plates 64, so that each of the buckles 58 can extend into each of the buckle holes 642a, 666 and engage with each of the buckle holes 642a, 666 to prevent the top cover 54 from loosening. It is worth mentioning that each buckle 58 can form a supporting structure, so that the hole edge of the buckle hole 642a of the fold 642 of each first plate 64 can be located on the side of each buckle 58, so that when each first plate 64 is pushed by external force, the hole edge of each buckle hole 642a can be against the side of each buckle 58, thereby increasing the strength of each first plate 64.

To remove the top cover 54, press each buckle 58 inward, then flip the top cover 54 upward to remove the top cover 54.

The door panel 68 is provided with a handle 70. In this embodiment, the handle 70 is provided on the outer surface 68a of the door panel 68 through a hinge frame 72. The material of the handle 70 can be a heat-insulating material, such as wood, bakelite, etc. As shown in FIG. 28 , the hinge frame 72 has a hinge 722 and a stopper 724. The handle 70 is hinged to the hinge 722. The stopper 724 is located on one side of the hinge 722. The handle 70 can be pivoted between a first position P41 and a second position P42. When the handle 70 is at the first position P41, a free end 702 of the handle 70 is close to the door panel. When the handle 70 is at the second position P42, the free end 702 of the handle 70 is away from the outer surface 68a of the door panel 68, and the other side of the handle 70 abuts against the barrier rod 724 to limit a pivot angle θ of the handle 70. The pivot angle θ of the handle 70 between the first position P41 and the second position P42 is greater than 90 degrees, preferably between 110 and 130 degrees. In this embodiment, the pivot angle θ is substantially 120 degrees.

The user can pull the handle 70 to flip the door panel 68 down. As shown in FIG. 29, when the door panel 68 is located at the open position P1 and the handle 70 is located at the second position P42, the free end 702 of the handle 70 abuts against a bearing surface F. In this way, the handle 70 forms a support frame for the door panel 68, increasing the load-bearing capacity of the door panel 68, allowing the user to temporarily place food, pots, or grills on the open door panel 68.

The above is only the preferred feasible embodiment of the present invention. Any equivalent changes made by applying the present invention specification and the scope of patent application should be included in the patent scope of the present invention.
