Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0027] The utility model is further described below in conjunction with the accompanying drawings:

[0028] The cooking appliance of this embodiment may be an oven, a microwave oven, an air fryer, etc., wherein the oven may be a household oven, a commercial oven, a microwave oven, a steam oven, etc.

[0029] Taking commercial ovens as an example, considering the need to meet the cooking needs of a large number of baked ingredients, the baking space is generally designed to be relatively large, and the size of commercial ovens is relatively large. In addition, considering that commercial ovens are frequently used and need to be easy for users to operate, the oven door generally adopts a side-opening method, which is usually connected to the oven with a hinge to avoid the oven door extending out of the operating table when it is open to block the user from approaching the oven, making it inconvenient to take and put ingredients in the oven. The problem with this type of commercial oven in use is that a larger commercial oven must be equipped with a larger oven door body. In frequent use scenarios, when the user opens the door body to the maximum position, the end position will block the door body and generate a rebound force, causing the door body to bounce back after opening. At this time, if the larger door body collides with the user, it is easy to cause injury to the user. In addition, when the user wants to bake multiple layers at the same time, the oven door will close again before the ingredients are placed, which causes the trouble of opening the door repeatedly.

[0030] Based on the above practical difficulties, the hinge assembly proposed in this embodiment can keep the door at an open angle when opening the door, so as to avoid the risk of the door rebounding and colliding with the user, and the trouble of repeatedly opening the door. In addition, the hinge assembly provided in this embodiment can ensure the reliability of the door in frequent use.

[0031] like Figure 1-Figure 2 As shown, a hinge assembly is applied to a cooking utensil (not shown in full in the figure), the cooking utensil includes a box body 1 and a door body 2, wherein a cooking space is formed in the box body 1 to cook the food placed therein, and the door body 2 is used to open or close the cooking space, so as to facilitate the taking and placing of food in the cooking space. The hinge assembly of this embodiment includes a hinge main shaft 6, which provides a basis for the rotation when opening and closing the door body 2, that is, the door body 2 rotates around the box door 1 with the hinge main shaft 6 as the center. The hinge main shaft 6 is connected to a suspension mechanism 4, and the suspension mechanism 4 can be used to keep the door body 2 at an open angle to prevent the door body 2 from rebounding and closing after being opened. In this embodiment: the suspension mechanism 4 includes a damping sleeve 41 arranged around the hinge main shaft 6, specifically, the damping sleeve 41 can be arranged on the periphery of the hinge main shaft 6, or the damping sleeve 41 is installed on other components and surrounds the hinge main shaft 6 in projection. The damping sleeve 41 includes a first damping sleeve connected to the box body 1, and a second damping sleeve connected to the door body 2, and the first damping sleeve and the second damping sleeve are provided with concave-convex structures on opposite sides. In this way, when the door body 2 needs to be opened or closed, the door body 2 will rotate around the box body 1 with the hinge main axis 6 as the center. At this time, the concave-convex structure of the first damping sleeve is engaged with the concave-convex structure of the second damping sleeve, so as to keep the door body 2 at the angle opened by the user, that is, the concave-convex structure of the first damping sleeve and the second damping sleeve is used to impose a restriction on the door body 2 during rotation to prevent it from rotating freely around the hinge main axis 6, thereby avoiding the trouble of rebounding and closing due to rebound during rotation, colliding with the user or needing to open it again.

[0032] In this embodiment: at least one of the hinge main shaft 6 and the suspension mechanism 4 is provided with a lubrication structure, that is, the lubrication structure can be designed on the hinge main shaft 6 or the suspension mechanism 4 alone, or the lubrication structure can be designed on both the hinge main shaft 6 and the suspension mechanism 4. The lubrication structure is used to reduce the friction generated by the rotating door body 2 on the concave-convex structure, thereby reducing the wear of the concave-convex structure of the damping sleeve 41 caused by the door body 2 during rotation, so as to improve the reliability of the concave-convex structure, especially in the scenario where the commercial oven is frequently used, the service life of the entire hinge assembly can be increased.

[0033] In this embodiment: the concave-convex structure includes a protrusion 421 and a recess 422. The protrusion 421 and the recess 422 of the first damping sleeve are staggered with the protrusion 421 and the recess 422 of the second damping sleeve in the circumferential direction. That is, the first damping sleeve is designed with alternating protrusions 421 and recesses 422 along the circumferential direction. Similarly, the second damping sleeve is also designed with alternating protrusions 421 and recesses 422 along the circumferential direction. The specific number of protrusions 421 and recesses 422 can be adjusted as needed, and this embodiment does not impose any specific restrictions. Figure 1 , 2 As shown, the transition profile of the protrusion 421 and the recessed portion 422 is an arc, and, in order to facilitate the smooth engagement of the door body 2 and the box body 1 after the two are assembled, the protrusion 421 of the first damping sleeve corresponds to the recessed portion 422 of the second damping sleeve, and the recessed portion 422 of the first damping sleeve corresponds to the protrusion 421 of the second damping sleeve. When the door body 2 is rotated, the second damping sleeve connected to the door body 2 rotates together with the door body 2, and then, the protrusion 421 of the second damping sleeve climbs out of the recessed portion 422 of the first damping sleeve connected to the box body 1, and after crossing the adjacent protrusion 421, it slides downward into the other recessed portion 422 under the action of gravity, thereby completing the door body 2 to remain at its opening angle after rotation.

[0034] In this embodiment: the lubrication structure includes a lubrication channel and a lubricating substance disposed in the lubrication channel. Specifically, the lubrication channel may be a hole, a groove or other structure, and the lubricating substance may be at least one of lubricating oil and lubricating grease. In one implementation of this embodiment, the lubrication channel is disposed on at least one of the concave-convex structure surface of the first damping sleeve and the concave-convex structure surface of the second damping sleeve. That is, by designing a lubrication channel on the surface of the concave-convex structure, the concave-convex structure in contact friction can be directly lubricated. For example, Figure 3 As shown, a lubrication hole is designed on the surface of the concave-convex structure, and lubricating oil / grease is filled in the lubrication hole. In this way, when the concave-convex structure surfaces of the first damping sleeve and the second damping sleeve engage with each other during rotation of the door body 2, the lubrication structure designed on the surface of the concave-convex structure will reduce the friction between the two, thereby increasing the service life of the entire hinge assembly and avoiding problems such as the door body 2 being stuck when opening due to friction loss.

[0035] Specifically, the lubrication channel is arranged in the recessed portion 422 of the concave-convex structure, and the lubricating material is at least one of lubricating oil and grease, which is conducive to keeping the lubricating oil / grease filled in the lubrication channel in the filling position, and can fill the recessed portion 422 with more lubricating oil / grease than the lubrication channel, thereby providing more lubrication for the concave-convex structure and reducing friction loss.

[0036] In other implementations of this embodiment: a first groove is provided on the outer side of the hinge main shaft 6, a second groove is provided on the inner side of the damping sleeve 41, and the first groove and the second groove are enclosed to form a lubrication channel. That is, a lubrication channel is formed between the hinge main shaft 6 and the damping sleeve 41, and a lubricating substance is filled in the lubrication channel to reduce the friction between the hinge main shaft 6 and the damping sleeve 41 caused by the rotation of the door body 2.

[0037] In this embodiment: the damping sleeve 41 is made of a rigid material, specifically, can be made of hard metal materials such as steel and iron, so as to meet the heavy weight support requirements, and through the designed lubrication structure, it can meet the heavy weight support requirements of the door body 2 while achieving smooth opening and closing of the door body 2 and long-term, frequent and reliable use.

[0038] In this embodiment: the hinge assembly also includes a hinge seat 3, wherein the hinge main shaft 6 is installed on the hinge seat 3, and the hinge seat 3 is connected to the box body 1. Specifically, the hinge seat 3 includes a vertically arranged connection portion and a horizontally arranged installation portion, and the hinge main shaft 6 and the first damping sleeve are arranged at the installation portion. That is, the cross-section of the hinge seat 3 is roughly L-shaped, the vertically arranged connection portion is connected to the box body 1, and the horizontally arranged installation portion, the hinge main shaft 6 and the first damping sleeve provide an installation foundation, so that the hinge assembly is installed on the box body 1 using the hinge seat 3, which can reduce the structural changes to the box body 1 caused by adding the hinge assembly.

[0039] Working principle: When the door body 2 is installed in the box body 1, the second damping sleeve connected to the door body 2 will be sleeved on the outer periphery of the hinge main shaft 6. In this way, when the user needs to open the door body 2, the door body 2 is rotated, and the second damping sleeve connected thereto will follow the door body 2 to rotate around the hinge main shaft 6. At this time, the concave-convex structure of the first damping sleeve and the second damping sleeve will provide a restriction on the rotation of the door body 2 around the hinge main shaft 6, so that the door body 2 can be kept at an open angle to prevent it from rotating freely around the hinge main shaft 6, thereby preventing the door body 2 from rebounding and closing due to the rebound force during the rotation of the door body 2, and then avoiding the trouble of the door body 2 rebounding and colliding with the user and the need to open the door body 2 frequently. At the same time, during the rotation, the friction caused by the rotational contact of the concave-convex structure can be reduced by the lubrication structure designed in the hinge main shaft 6 and / or the hovering mechanism 4, so as to improve the reliability of the hinge assembly in the frequent opening of the door body 2.

[0040] This embodiment also provides a cooking utensil, including a box body 1, on which a door body 2 is arranged, wherein the above-mentioned hinge assembly is installed at least at the bottom connection between the box body 1 and the door body 2, and the hinge assembly can be used to keep the door body 2 of the cooking utensil at an open angle, so as to avoid the door body 2 rebounding and colliding with the user during opening, and to avoid the trouble of opening the door body 2 multiple times when baking multiple layers at the same time, and to ensure reliability in frequent use scenarios. Specifically, only one hinge assembly can be arranged at the bottom connection between the box body 1 and the door body 2, and the hinge assembly can also be designed at the upper end, middle end, etc. connection between the box body 1 and the door body 2.

[0041] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
