Description

Technical Field

[0001] This utility model relates to the field of grilling machine technology, specifically a grilling machine shaft disassembly structure. Background Technology

[0002] Grills, a common kitchen appliance, are widely used in both home and commercial cooking. Their design typically consists of two main parts: an upper shell and a lower shell. The upper shell holds the upper baking tray, while the lower shell holds the lower baking tray. These two sections work together to heat and cook food. To enhance flexibility and convenience, the upper and lower shells are usually connected by a hinge structure, allowing the upper shell to flip relative to the lower shell for easy placement and removal of food. This also allows the grill to be folded away for storage when not in use, saving space. However, in actual use, after a period of cooking, food residue and grease often remain on the baking trays. These residues not only affect the taste and hygiene of the food but can also negatively impact the grill's performance, such as reducing heating efficiency or producing unpleasant odors. Therefore, regular cleaning and maintenance of the grill are crucial for maintaining its optimal working condition and extending its lifespan.

[0003] Traditional grill designs present inconveniences in terms of cleaning. Specifically, because the upper and lower shells are tightly connected by a hinge structure, users often encounter difficulties in disassembling and separating the upper and lower grill pans for individual cleaning. This design increases the difficulty of cleaning.

[0004] To solve the above problems, people have designed a structure in which the upper and lower baking pans can be separated. For example, a barbecue machine disclosed in CN118766323 A adopts a structure with a first plug-in component, a first plug-in support, a second plug-in component, a second plug-in support, a first plug post, an inner concave tooth groove, a first extended arc plate, and a second extended arc plate. This structure can separate the upper and lower baking pans and facilitate separate cleaning. However, it has the problem of being too complex.

[0005] Therefore, developing a simple structure for disassembling the rotating shaft of a grill is the direction that researchers in this field wish to explore. Utility Model Content

[0006] In view of the above-mentioned defects in the prior art, the purpose of this utility model is to provide a disassembly structure for the rotating shaft of a grill.

[0007] The technical solution of this utility model is: a grill machine shaft disassembly structure, including an upper shell and a lower shell. The upper shell has a shaft on both the left and right sides of the lower rear end, and the lower shell has a bearing fixed on both the left and right sides of the upper rear end. The bearing has a slot for the shaft to be inserted into. The slot includes an inlet slot, a movable slot and a circular slot connected from top to bottom. The shaft is a flat shaft with a major diameter and a minor diameter. The width of the inlet slot is greater than the minor diameter of the shaft. The width of the movable slot is greater than the minor diameter of the shaft and less than the major diameter of the shaft. The inner diameter of the circular slot is greater than the major diameter of the shaft.

[0008] Furthermore, the side walls and top of the slot are open to allow the rotating shaft to be inserted.

[0009] Furthermore, the inlet groove has a flared opening with the opening facing upwards, and the width of the flared opening gradually decreases from top to bottom.

[0010] Furthermore, after the upper and lower shells are assembled together, the rotating shaft is housed in the circular groove and rotates with the groove. When the rotating shaft rotates until its short diameter aligns with the movable groove, the upper shell is lifted up, causing the rotating shaft to move out of the slot.

[0011] The advantages of the grill shaft disassembly structure provided by this utility model are: simple structure, by designing a slot with a specific shape to cooperate with the rotating shaft, the user only needs to rotate the upper shell relative to the lower shell to a specific angle (i.e. when the short diameter of the rotating shaft is aligned with the movable slot) to easily lift the upper shell and disassemble the rotating shaft from the slot. This process greatly simplifies the complicated disassembly steps required for cleaning or maintenance of traditional grills and improves the user's operational convenience.

[0019] To provide a more intuitive and complete understanding of the technical solution of this utility model, the following non-limiting features are described in conjunction with the accompanying drawings:

[0020] like Figure 1 — Figure 6 As shown, a grill machine shaft disassembly structure includes an upper shell 1 and a lower shell 2. The upper shell 1 has a shaft 3 on both the left and right sides of its lower rear end, and the lower shell 2 has a bearing seat 4 fixed on both the left and right sides of its upper rear end. The bearing seat 4 has a slot 41 for the shaft 3 to be inserted into. The slot 41 includes an inlet slot 411, a movable slot 412, and a circular slot 413 connected from top to bottom. The shaft 3 is a flat shaft with a major diameter and a minor diameter. The width of the inlet slot 411 is greater than the minor diameter of the shaft 3. The width of the movable slot 412 is greater than the minor diameter of the shaft 3 and less than the major diameter of the shaft 3. The inner diameter of the circular slot 413 is greater than the major diameter of the shaft 3.

[0021] A flat axis is a non-cylindrical axis that is symmetrically set on both sides as planes. For example... Figure 5 As shown, the minor axis is the distance between the two planes above and below in the figure, and the major axis is the maximum distance between the two arc surfaces on the left and right sides in the figure.

[0022] To facilitate the insertion of the rotating shaft 3 into the slot 41, the side wall and top of the slot 41 are open for the rotating shaft 3 to be inserted.

[0023] like Figure 6 As shown, the inlet slot 411 has a flared opening, with the opening facing upwards and the width of the flared opening gradually decreasing from top to bottom. The flared opening is designed to facilitate the insertion of the rotating shaft 3.

[0024] After the upper shell 1 and lower shell 2 are assembled together, the rotating shaft 3 is housed in the circular groove 413 and rotates with the circular groove 413. When the rotating shaft 3 rotates until its short diameter aligns with the movable groove 412, as... Figure 5 As shown, lift the upper shell 1 upwards to move the rotating shaft 3 out of the slot 41. Figure 3 As shown, the minor diameter of the rotating shaft 3 is not aligned with the movable groove 412 at this time, and it cannot be disassembled.

[0025] The present invention provides a simple structure for disassembling the rotating shaft of a grill. By designing a slot 41 with a specific shape to cooperate with the rotating shaft 3, the user only needs to rotate the upper shell 1 relative to the lower shell 2 to a specific angle (i.e., when the short diameter of the rotating shaft 3 is aligned with the movable slot 412) to easily lift the upper shell 1 and disassemble the rotating shaft 3 from the slot 41. This process greatly simplifies the complicated disassembly steps required for cleaning or maintenance of traditional grills and improves the user's ease of operation.

[0026] Of course, the above are only preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any simple modifications and equivalent structural changes made based on the contents of the present utility model specification and drawings should also be included within the patent protection scope of the present utility model.
