[0046] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0047] like Figure 1 As shown in Figure 8, the present invention provides a steam oven, including an oven door and a heating chamber 1, with a built-in support frame 2 suitable for carrying food, and also includes: a lifting assembly, which is arranged in the heating chamber 1, and includes a fixed part and a movable part, the fixed part is arranged on the inner wall of the heating chamber 1, and the movable part is connected to the support frame 2, suitable for moving in a vertical direction along the fixed part under the action of an external force, and has a locking position for locking with the fixed part.

[0048] With this arrangement, the support frame 2 connected to the movable part can change in height as the movable part moves, thereby achieving the purpose of adjustable height of the support frame 2 and ensuring the user's needs for various ingredients and cooking methods. At the same time, the movable part can be locked with the fixed part to ensure that the support frame 2 can be stably maintained at a required height to achieve the function of receiving food. This solution overcomes the defect that the height of the support frame 2 of the steam oven in the prior art cannot be adjusted.

[0049] In this embodiment, the fixed part is a vertical guide rail 3 relatively arranged on the inner wall of the heating cavity 1 adjacent to the oven door, and the movable part is a slider 4 engaged with the guide rail 3 and movably connected.

[0050] As a convertible embodiment, the guide rails 3 may be arranged on only one inner side wall, or a plurality of guide rails 3 may be arranged on each inner side wall of the heating cavity 1 adjacent to the oven door.

[0051] As another alternative embodiment, the guide rail 3 can be arranged obliquely on the inner wall of the heating chamber 1 .

[0052] The height change of the support frame 2 is achieved by adopting the form of a guide rail 3 in conjunction with a slider 4. This simple structure is convenient for installation and disassembly of the lifting component. At the same time, the structure is small in size and light in weight, and does not occupy the original cooking space in the heating chamber 1. In addition, multiple groups of such structures can be arranged in the heating chamber 1 to enhance the stability of the lifting device during movement and the mechanical properties of the support frame 2 for carrying food after the slider 4 is fixed.

[0053] There are several evenly arranged small holes 31 on the side of the guide rail 3 that fits the movement trajectory of the slider 4. The slider 4 is provided with a retractable protrusion 41 that is suitable for engaging with the small hole 31. In the present embodiment, the small hole 31 is a round hole and the protrusion 41 is a cylinder. As a convertible implementation method, the small hole 31 and the protrusion 41 can also be other matching shapes such as square holes and square protrusions.

[0054] A retractable protrusion 41 is provided on the slider 4 and is fixedly engaged with the small hole 31. Such a setting structure is simple. After engagement, the force direction borne by the protrusion 41 is perpendicular to the force direction required for release, and problems such as slippage are not easy to occur. The mechanical properties are better and the load-bearing weight is higher. At the same time, the small holes 31 are evenly arranged on the guide rail 3. The fixed height of the slider 4 can be selected according to the position of the small holes 31, so that the support frame 2 can be fixed at the height required by the user, which is convenient for cooking different types of food.

[0055] The slider 4 includes: a housing 42, which is provided with a receiving space 43 with a through hole 431. The housing 42 is engaged with the guide rail 3 and slides relative to each other. The through hole 431 is arranged corresponding to the small hole 31; a movable block 44 is arranged in the receiving space 43 and is provided with a protrusion 41 arranged toward the through hole 431; an elastic member is arranged between the movable block 44 and the housing 42, and is suitable for controlling the protrusion 41 to protrude or retract into the receiving space 43 under the action of an external force. In this embodiment, the guide rail 3 is arranged in a "concave" shape, and the housing 42 surrounds the two sides of the protrusion of the guide rail 3 and engages with it. The through hole 431 and the small hole 31 are both round holes, such as Figure 7 -8, the movable block 44 is a rectangular shell lacking two adjacent faces, and the two adjacent faces of the shell are respectively provided with a protrusion 41 and a protrusion 441, and the elastic member is arranged on the inner side of the rectangular shell and partially extends out of the shell.

[0056] As an alternative embodiment, the elastic member may not be provided.

[0057] The housing 42 includes a seat body 421 and a fixing plate 422. The seat body 421 is engaged with the guide rail 3, and a slot body opening toward the support frame 2 is provided inside. A through hole 431 is provided on the slot body. The fixing plate 422 is fixedly connected to the seat body 421, and a receiving space 43 formed with the slot body is provided. The fixing plate 422 is provided with a long hole corresponding to the opening on the slot body. The movable block 44 is also provided with a protrusion 441, which protrudes from the long hole and is suitable for reciprocating movement in the long hole. In this embodiment, the extension direction of the protrusion 441 is perpendicular to the extension direction of the protrusion 41.

[0058] In this embodiment, the elastic member is a spring 45, and a support column 442 is provided on the movable block 44. The extension direction of the support column 442 is arranged parallel to the extension direction of the protrusion 41. The spring 45 is sleeved on the support column 442, and the end facing away from the movable block 44 is in contact with the inner wall of the accommodating space 43. The setting of the support column 442 plays a role in fixing the spring 45, preventing the spring 45 from deflecting or slipping, and at the same time ensures that the direction of the elastic force of the spring 45 is consistent with the movement direction of the protrusion 41, so that the spring 45 can make the protrusion 41 telescopically move in the small hole 31, playing a role in controlling the locking and unlocking between the guide rail 3 and the slider 4.

[0059] As a convertible implementation, the elastic member can be a silicone sheet, etc., which cooperates with the movable block 44 in the shape of a complete rectangular parallelepiped. As another convertible implementation, the support column 442 can also be omitted.

[0060] The support frame 2 is provided with a connecting portion 21, which is fixedly connected to the protrusion 441. The support frame 2 is connected and fixed to the protrusion 441, and the user can realize the movement control of the protrusion 441 by pulling the support frame 2. The protrusion 441 is a part of the movable block 44. The movement of the protrusion 441 can be converted into the same direction movement of the protrusion 41 on the movable block 44, so that the user can control the locking and unlocking between the guide rail 3 and the slider 4. In this embodiment, multiple groups of connecting portions 21 can be provided on the support frame 2, and they are respectively connected and fixed to multiple groups of lifting components on an inner side wall of the heating chamber 1.

[0061] Fixing screws 32 are protruding from the middle of both ends of the guide rail 3. The fixing screws 32 are provided to, on the one hand, detachably fix the guide rail 3 to the inner wall of the heating chamber 1, and on the other hand, to limit the movement stroke of the slider 4 to prevent the slider 4 from slipping off the guide rail 3 during the unlocking movement, so that the support frame 2 connected to the slider 4 and the food carried by it fall off.

[0062] The small hole 31 is arranged on the side of the guide rail 3 away from the oven door. In this way, the user can unlock the locked state of the guide rail 3 and the slider 4 by pulling the support frame 2 outward from the oven door. Compared with the small hole 31 arranged at other positions, the user's touch locking method is more convenient and easy. In this embodiment, the opening direction of the small hole 31 is parallel to the horizontal plane and is arranged toward the oven door.

[0063] In addition, in the present embodiment, the fixing means of the fixing piece 422 and the shell 42, and the protrusion 441 and the connecting portion 21 are fixed by screws. As a convertible implementation method, it can also be fixed by welding or bonding.

[0064] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
