[0039] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0040] This embodiment provides an oven frame, which can be used in an oven to support the oven body and store objects such as gas cylinders in the oven, thereby improving the appearance and reliability of the oven frame.

[0041] like Figures 1 to 3 As shown, the oven frame includes a frame body 2, a door panel 3, and a door hinge assembly 1. The frame body 2 has a storage space with a side opening. The door panel 3 is installed at the side opening of the frame body 2 and one side is hinged to the frame body 2 through the door hinge assembly 1, so that the door panel 3 can rotate relative to the frame body 2 to open or close the opening.

[0042] In one embodiment, two door panels 3 are provided, and the two door panels 3 are arranged in a split-type arrangement, that is, the sides of the two door panels 3 facing away from each other are hingedly connected to the frame 2 via the door hinge assembly 1. In other embodiments, only one door panel 3 may be provided, and either side of the door panel 3 is rotatably connected to the frame 2 via the door hinge assembly 1.

[0043] The door axis assembly 1 includes a door axis part 11, a mounting seat 12 and an adjusting bolt 13. The door axis part 11 includes a door axis body 111 and a guide portion 113 and an adjusting portion 112 protruding from the door axis body 111. The door axis body 111 extends along a first direction, and the guide portion 113 and the adjusting portion 112 both extend along a second direction, which is perpendicular to the first direction. The guide portion 113 and the adjusting portion 112 can both be slidably inserted into the mounting seat 12 along the second direction. The door axis body 111 is located outside the mounting seat 12, and an adjusting threaded hole is provided on the end face of the adjusting portion 112. The adjusting bolt 13 passes through the mounting seat 12 along the second direction, and the end thread is screwed into the adjusting threaded hole.

[0044] When the door hinge assembly 1 is connected between the door panel 3 and the frame 2, the first direction is vertical and the second direction is along the width direction of the side opening. The mounting seat 12 is installed on one of the door panel 3 and the frame 2, and the other of the door panel 3 and the frame 2 is rotatably connected to the door hinge member 11.

[0045] For the convenience of subsequent description, the side of the door panel 3 that cooperates with the door shaft assembly 1 is referred to as the hinge side, and the other opposite side of the door panel 3 is referred to as the opening and closing side.

[0046] In this embodiment, the mounting seat 12 is mounted on the frame 2, and the door shaft 11 is rotatably connected to the door panel 3 to facilitate the installation of the door shaft assembly 1. That is, under this arrangement, when the gap between two adjacent door panels 3 or between a door panel 3 and the frame 2 is large, the door shaft 11 is slid toward the mounting seat 12 by screwing the adjusting bolt 13, thereby reducing the distance between the door shaft body 111 and the outer surface of the frame 2, so that the opening and closing side of the door panel 3 is closer to the edge of the other door panel 3 or the side opening, thereby reducing the door gap; when compression occurs between the two door panels 3 or the opening and closing side of the door panel 3 is compressed against the frame 2, the door shaft 11 is moved in a direction away from the outer side of the frame 2 by screwing the adjusting bolt 13, so that the opening and closing side of the door panel 3 is moved along the other side edge away from the other door panel 3 or the opening through the cooperation between the door shaft body 111 and the intersection side of the door panel 3, thereby preventing the opening and closing side of the door panel 3 from being compressed against the other door panel 3 or the frame.

[0047] In other embodiments, the mounting seat 12 is installed on the door panel 3, and the door axis 11 cooperates with the frame 2. At this time, when it is necessary to increase the gap between the opening and closing side of the door panel 3 and the frame 2 or another door panel 3, the adjusting bolt 13 is screwed to make the door axis 11 slide in the direction close to the mounting seat 12. When it is necessary to increase the gap between the opening and closing side of the door panel 3 and the frame 2 or another door panel 3, the adjusting bolt 13 is screwed to make the door axis 11 slide in the direction away from the mounting seat 12.

[0048] That is, the door axis assembly 1 and the oven frame provided in this embodiment are provided with an adjusting bolt 13 and a door axis part 11, and the adjusting bolt 13 rotates through the mounting seat 12 and is transmission-connected to the door axis part 11, so that the distance between the door axis main body 111 and the mounting seat 12 can be adjusted by rotating the adjusting bolt 13, thereby adjusting the relative position between the door panel 3 and the frame 2, avoiding the problem of a large door gap or uneven extrusion between the door panel 3 and the frame 2 due to processing or assembly errors, thereby improving the safety of use and the appearance of the oven frame; at the same time, since the guide part 113 and the adjusting part 112 extend in the same direction and are both slidably inserted in the mounting seat 12, the door axis part 11 can only slide along the second direction and cannot rotate, thereby improving the reliability of adjustment; furthermore, the guide part 113 and the adjusting part 112 are concentrated on one side of the door axis main body 111, which is conducive to simplifying the structure of the mounting seat 12, reducing the size of the mounting seat 12, thereby simplifying the overall structure of the door axis assembly 1, reducing the occupied space and facilitating the hidden installation of the mounting seat 12.

[0049] In one embodiment, when the door panel 3 is in a state of closing the side opening, the mounting seat 12 is located on the rear side of the door panel 3, thereby enabling hidden installation of the mounting seat 12, improving the aesthetics of the door axis assembly 1 after installation, and improving the aesthetics of the installation of the oven frame; at the same time, this arrangement allows the adjusting bolt 13 to be hidden inside the rear side of the door panel 3, avoiding exposure of the adjusting bolt 13 and causing accidental collision.

[0050] To further enhance the overall aesthetics of the oven frame, the door panel 3 comprises a bent, connected panel body 31 and a mounting side portion 32. The mounting side panel 21 is perpendicular to the panel body 31, and the side of the mounting side portion 32 facing away from the panel body 31 forms the hinged side of the door panel 3. This arrangement facilitates positioning the door hinge assembly 1 rearward relative to the front side of the door panel 3, thereby reducing the likelihood of the door hinge assembly 1 scratching the user. In other embodiments, the door panel 3 can also be a flat, plate-like structure. Furthermore, the mounting side panel 21 is an arc-shaped structure, with the tangents at both ends perpendicular to each other, to enhance the overall aesthetics of the oven frame.

[0051] Furthermore, a hinge portion 33 is protruding from the hinged side of the door panel 3. The hinge portion 33 has a hinge hole 331. The door shaft body 111 is rotatably inserted into the hinge hole 331, thereby improving the convenience of rotating and installing the door panel 3 and the door shaft body 111. Furthermore, a hinge plate is connected outwardly to the installation side 32. The hinge plate is rolled around the hinge portion 33, and the hollow space of the roll forms the hinge hole 331, thereby facilitating the processing of the hinge portion 33.

[0052] In one embodiment, the door hinge body 111 includes a mounting shaft portion 1111 and a rotating shaft portion 1112 that are coaxially connected. A guide portion 113 and an adjustment portion 112 are protruding from the side wall of the mounting shaft portion 1111. The diameter of the mounting shaft portion 1111 is larger than the diameter of the rotating shaft portion 1112. As a result, a limited step surface is formed between the mounting shaft portion 1111 and the rotating shaft portion 1112. When the door hinge assembly 1 is installed on the frame 2, the rotating shaft portion 1112 is located on the upper side of the mounting shaft portion 1111. The rotating shaft portion 1112 is inserted into the hinge hole 331, and the hinge portion 33 can abut against the limiting step surface to support the hinge portion 33 through the limiting step surface, thereby supporting the door panel 3 and preventing the door panel 3 from falling downward.

[0053] To facilitate installation of the mounting base 12 on the frame 2, the frame 2 has two side panels 21 disposed opposite and spaced apart in the second direction. A side opening is formed between the first ends of the two side panels 21. At least one side panel 21 is connected to a front flange portion 22 in a direction toward the other side panel 21. The mounting base 12 is located on the side of the front flange portion 22 facing away from the door panel 3. This allows the mounting base 12 to be concealed within the frame 2, improving the overall structural compactness and aesthetics of the door hinge assembly 1 and the oven frame. Furthermore, the provision of the front flange can enhance the structural strength of the frame 2 at the edge of the side opening, reducing the probability of deformation of the frame 2. Furthermore, it can prevent the sharp edges on the front side of the frame 2 from scratching the door panel 3.

[0054] In one embodiment, the end of the front flange 22 away from the side panel 21 is bent into a side flange 23 in a direction away from the door panel 3. The mounting seat 12 is located between the side panel 21 and the side flange 23, and the adjustment bolt 13 passes through the side flange 23 and the mounting seat 12 in sequence. This arrangement allows the mounting seat 12 to be located in the space enclosed by the side panel 21, the front flange 22, and the side flange 23, further concealing the mounting seat 12 and improving the overall structural aesthetics of the oven frame. Furthermore, the provision of the side flange 23 further strengthens the structure at the edge of the side opening.

[0055] In one embodiment, the mounting base 12 and the side plate 21 are connected by fastening screws 14 provided therethrough, and the fastening screws 14 penetrate from the outside of the side plate 21 to the inside of the side plate 21. In other embodiments, the mounting base 12 can also be connected to the side flange portion 23 by fastening screws 14.

[0056] To improve the stability of the door shaft 11 on the mounting base 12, in one embodiment, guide portions 113 are provided on opposite sides of the adjustment portion 112 along the first direction, thereby increasing the stability and reliability of the door shaft 11 sliding relative to the mounting base 12 along the second direction. In other embodiments, only one guide portion 113 may be provided.

[0057] Furthermore, the guide portion 113 and the adjustment portion 112 are both cylindrical structures, and the diameter of the guide portion 113 is smaller than the diameter of the adjustment portion 112. This facilitates the opening of an adjustment threaded hole on the adjustment portion 112 while reducing the size of the guide portion 113, thereby reducing the length requirement of the installation shaft portion 1111, reducing the structural size of the door shaft assembly 1, and simplifying the structure of the door shaft assembly 1.

[0058] In order to further simplify the structure of the door hinge assembly 1, the mounting seat 12 has a hollow cavity extending through it in a third direction, which is perpendicular to both the first direction and the second direction, so as to reduce the overall weight of the door hinge assembly 1 and reduce the difficulty of processing the door hinge assembly 1. Specifically, the mounting seat 12 has a first side portion 121 and a second side portion 122 forming opposite side walls of the hollow cavity, the guide portion 113 and the adjustment portion 112 are slidably provided on the first side portion 121, and the adjustment bolt 13 passes through the second side portion 122 and the first side portion 121 in sequence.

[0059] The first side portion 121 is provided with an adjustment hole 1212 and a guide hole 1211 . The guide holes 1211 are provided in a one-to-one correspondence with the guide portions 113 . The adjustment portion 112 is slidably inserted into the adjustment hole 1212 , and the guide portion 113 is slidably inserted into the guide hole 1211 .

[0060] In one embodiment, the first side portion 121 and the second side portion 122 are arranged parallel to each other and spaced apart, so that the mounting base 12 has an overall rectangular frame structure, which facilitates installation of the mounting base 12 on the frame 2 and simplifies the overall structure of the mounting base 12. A connecting portion 123 is connected between the ends of the first side portion 121 and the second side portion 122, so that the first side portion 121, the second side portion 122, and the two mounting portions together form a hollow cavity.

[0061] The first side portion 121 and the second side portion 122 are both plate-shaped structures, and the connecting portion 123 is formed by vertically bending the first side portion 121 or the second side portion 122 , thereby facilitating the processing of the mounting seat 12 and reducing the processing difficulty of the mounting seat 12 .

[0062] In one embodiment, the connecting portion 123 is formed by bending the second side portion 122, and the connecting portion 123 is bent in a direction away from the second side portion 122 to provide a fixing portion 124, and the fixing portion 124 is fitted and connected to the inner side of the first side portion 121, thereby improving the processing convenience of the mounting base 12 and helping to ensure the overall structural strength and rigidity of the mounting base 12.

[0063] In one embodiment, fastening holes 1213 are defined on the first side portion 121, and mounting holes are defined on the frame 2. The mounting holes are aligned with the fastening holes 1213 and are arranged one-to-one. The mounting base 12 and the frame 2 are connected via fastening screws 14 that pass through the fastening holes 1213 and the mounting holes. Two fastening holes 1213 are spaced apart on the first side portion 121, and the guide hole 1211 and the adjustment hole 1212 are located between the two fastening holes 1213 to prevent interference between the structures.

[0064] The fixing portion 124 is provided with a clearance hole, and the fastening hole 1213 is arranged opposite the clearance hole to avoid the fastening screw 14. This arrangement allows the fastening holes 1213 to be located close to both ends of the first side portion 121, thereby meeting the installation and fastening requirements while reducing the size of the mounting base 12 in the first direction. At the same time, the connecting portion 123 also structurally strengthens the portion of the first side portion 121 where the fastening hole 1213 is provided.

[0065] In one embodiment, the first side portion 121 and the second side portion 122 define rod through-holes for the adjustment bolt 13 to pass through. The adjustment portion 112 is slidably inserted into one of the rod through-holes. A retaining member 15 is attached to the adjustment bolt 13. The retaining member 15 is positioned within the hollow cavity and prevents it from passing through the rod through-hole. The retaining member 15, through its contact with the first side portion 121 or the second side portion 122, prevents the adjustment bolt 13 from exiting the mounting base 12, ensuring the stability and reliability of the mounting of the adjustment bolt 13 on the mounting base 12. The rod through-holes on the first side portion 121 form the aforementioned adjustment through-holes 1212.

[0066] In one embodiment, the anti-slip component 15 is a nut threaded onto the adjusting bolt 13 to improve the installation convenience and stability of the anti-slip component 15 on the adjusting bolt 13. In other embodiments, the anti-slip component 15 can be a retaining spring or other structure clamped on the adjusting bolt 13.

[0067] The utility model also provides an oven, comprising an oven body and the oven frame. By adopting the oven frame, the reliability and aesthetic appearance of the oven can be improved, the structure of the oven can be simplified, the cost can be reduced, and the user experience can be improved.
