[0002] Commercial cooking, display cabinet and other equipment are widely used in hotels, restaurants, canteens and other commercial places to meet the dining needs of a large number of people. Such equipment usually needs to be operated multiple times for food storage and retrieval within a short period of time, so it is required to have efficient and convenient use performance. As an important part of commercial cooking equipment, the design of steam oven directly affects the efficiency and operation convenience of food preparation.
[0003] Commercial steam ovens, display cabinets and other equipment on the market are relatively large in size, and their door bodies usually adopt a side-opening door structure. However, this design has the following disadvantages in actual use: 1. The door body is inconvenient to fix after being opened. The traditional side-opening door structure cannot be stably stopped at a suitable angle after being opened, which requires the operator to hold the door body with one hand when storing or taking out food, affecting the operation efficiency and safety. The door body design of some steam ovens can be fixed at a specific angle, but the lower hinge structure is still simple in design and lacks flexibility, which cannot meet the needs of multi-angle and stable door opening and closing operation in commercial scenarios. 2. The door body structure is opened by turning downward, and the lower hinge adjustment is limited. The existing door body lower hinge structure cannot flexibly adjust the distance between the door body and the front end of the box in the front-back direction, which easily causes the door body to be jammed or the door seal to be not tight, affecting the sealing performance and cooking effect of the box.
[0004] In summary, the door body design of existing commercial steam ovens and display cabinets still has room for improvement in terms of structural optimization and use convenience, especially in terms of door opening and closing angle control, fixing method and hinge structure innovation, which needs to be further improved to improve the operation experience and use performance of the equipment.

[0033] Embodiment 1,
[0034] A door body positioning structure and cooking equipment, especially a side-opening door hinge system used in commercial steam ovens, aims to solve the problems of fixed opening angle of the door body, sealing performance and operation convenience.
[0035] In combination Figures 1-7 As shown in the figure, the cooking equipment includes a front-side opening box body 1, and the opening side of the box body 1 is pivotally connected with a door body 2 through a rotating shaft.
[0036] The door body positioning structure includes a support 3 fixedly connected with the lower part of the box body 1 of the cooking equipment and a limiting piece 4 fixed to the lower part of the door body 2. The support 3 is fixed to the lower part of the box body 1 through a support 5, the support 5 includes a horizontally extending support plate 51 and a vertically extending fixed plate 52, the support 3 is fixed to the upper surface of the support plate 51, so that the support 3 is located below the rotating shaft side of the door body 2, and the limiting piece 4 fixed to the lower part of the door body 2 is located above the support 3. The limiting piece 4 can rotate relative to the support 3, the upper surface of the support 3 is provided with a first limiting protrusion 31, and the lower surface of the limiting piece 4 is provided with a second limiting protrusion 41.
[0037] Under the action of external force, the door body 2 rotates to open, the limiting piece 4 rotates with the door body 2, and the second limiting protrusion 41 can pass over the first limiting protrusion 31; when the door body 2 is opened and no external force is applied, the first limiting protrusion 31 can limit the passing of the second limiting protrusion 41, limit the rotation of the limiting piece 4, and thus limit the rotation of the door body 2 to reset. When the door body 2 is opened and the second limiting protrusion 41 does not reach the first limiting protrusion 31, the second limiting protrusion 41 is in contact with the upper surface of the support 3, and the first limiting protrusion 31 is in contact with the lower surface of the limiting piece 4.
[0038] In order to enable the door body 2 to stay at a certain angle when it is opened, two first limiting protrusions 31 are provided, and one second limiting protrusion 41 can be limited between the two first limiting protrusions 31 after the door body 2 is opened. Alternatively, two second limiting protrusions 41 are provided, and one first limiting protrusion 31 can be limited between the two second limiting protrusions 41 after the door body 2 is opened.
[0039] In order to make the second limiting protrusion 41 more easily pass through the first limiting protrusion 31 during the rotation of the door body 2, the first limiting protrusion 31 is a circular arc boss extending radially along the first shaft hole 32, and the second limiting protrusion 41 is a circular arc boss extending radially along the second shaft hole 42. When a plurality of first limiting protrusions 31 are provided, they are spaced apart along the circumference of the first shaft hole 32; and when a plurality of second limiting protrusions 41 are provided, they are spaced apart along the circumference of the second shaft hole 42.
[0040] The edge of the first shaft hole 32 on the support 3 extends upward to form an annular wall to form a first shaft sleeve 33.

[0041] It should be noted that the door body 2 needs to be able to move axially along the rotation shaft, and when the second limiting protrusion 41 passes through the first limiting protrusion 31 during the rotation of the door body 2, the door body 2 and the limiting piece 4 move upward along the axis, and after the second limiting protrusion 41 passes through the first limiting protrusion 31, the door body 2 is reset downward under the action of gravity, so that the first limiting protrusion 31 can limit the passing of the second limiting protrusion 41.
[0042] In order to make the connection between the support 3 and the bracket 5 more stable, a positioning assembly is provided between the bracket 5 and the support 3, the positioning assembly includes a positioning block 34 and a positioning groove 53, one of the positioning block 34 and the positioning groove 53 is provided on the support 3, and the other is provided on the bracket 5, the positioning block 34 is inserted into the positioning groove 53, and the positioning groove 53 can be rectangular, square, waist-shaped, semicircular, etc.
[0043] According to the needs, the bracket 5, the support 3 and the limiting piece 4 can also be provided with threading holes 54 respectively, the three threading holes 54 are communicated, and the required light wire or temperature probe wire on the door body 2 passes through the three threading holes 54 and is introduced into the door body 2.
[0044] In order to better assemble and adjust the position, the positioning groove 53 is generally designed as a long strip hole or a waist-shaped hole, and after the positioning block 34 is inserted into the positioning groove 53, there is a space for moving forward and backward along the positioning groove 53, so as to facilitate the installation of the support 3, and after the appropriate position is found, the support 3 and the bracket 5 are locked and fixed by using screws or other fasteners.
[0045] Embodiment 2,
[0046] The difference between this embodiment and embodiment 1 is that the door body positioning structure in this embodiment is installed on the upper part of the cooking equipment box.
[0047] The door positioning structure comprises a support installed on the upper part of the cooking device cabinet and a limiting piece fixed to the lower part of the door body. The support is fixed on the cabinet, and the support comprises a horizontally extending support plate and a vertically extending fixing plate. The support is limitedly installed on the lower surface of the support plate, so that the support is located above the side of the door body pivot. The limiting piece fixed to the upper part of the door body is located below the support. The limiting piece can rotate relative to the support. The lower surface of the support is provided with a first limiting protrusion, and the upper surface of the limiting piece is provided with a second limiting protrusion.
[0048] The same as in example 1, under the action of external force, the door body rotates to open, and the limiting piece rotates with the door body. The second limiting protrusion can pass over the first limiting protrusion. When the door body is opened and no external force is applied, the first limiting protrusion can limit the passing of the second limiting protrusion, limit the rotation of the limiting piece, and thus limit the rotation of the door body to reset.

The compression spring pushes the support to move downward, so that the second limiting protrusion can limit the passing of the first limiting protrusion, and the door body is kept in an open state. When the door body is rotated to open or close under the action of external force, the compression spring is deformed by extrusion during the process that the first limiting protrusion passes over the second limiting protrusion, so that the support moves upward.
[0050] The positioning assembly arranged between the support frame and the support comprises a positioning block and a positioning groove. One of the positioning block and the positioning groove is arranged on the support, and the other is arranged on the support frame. The positioning block is inserted into the positioning groove. During the upward and downward movement of the support, the positioning block always remains at least partially in the positioning groove.
[0051] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features. Such modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
