[0004] To this end, the utility model provides a cooking utensil.

[0005] In view of this, the utility model proposes a cooking utensil, comprising: a furnace body, which is provided with an opening; a cover body, which is arranged on the furnace body and is rotatably connected to the side wall of the furnace body to open or close the opening; and an anti-friction part, at least a part of the anti-friction part is arranged between the cover body and the furnace body, and the cover body contacts the side wall of the furnace body through the anti-friction part.

[0006] The cooking utensil provided by the present invention comprises a stove body, a cover, and an anti-friction member. The stove body is provided with an opening, and the cover is mounted on the stove body and is rotatably connected to the side wall of the stove body to enable opening and closing of the opening. At least a portion of the anti-friction member is disposed between the cover and the stove body, so that the cover contacts the stove body through the anti-friction member. During the rotation of the cover, the cover does not directly rub against the stove body, thereby preventing abnormal friction noise during the opening and closing of the cover.

[0007] The cooking appliance provided by the present invention may also have the following additional technical features:

[0008] In some embodiments, optionally, the cooking appliance further comprises: a rotating member, which is provided through the furnace body and the cover body, the cover body is rotatably connected to the furnace body through the rotating member, and the anti-friction member is sleeved on the outer side of the rotating member.

[0009] In this embodiment, the cooking utensil also includes a rotating part, and the cover body is rotatably connected to the furnace body through the rotating part, wherein the anti-friction part is sleeved on the outside of the rotating part, thereby realizing the installation of the anti-friction part. There is no need to add other connecting structures to realize the installation of the anti-friction part, which reduces the use of parts and reduces costs, and also reduces the possibility of the anti-friction part falling off.

[0010] In some embodiments, optionally, a first through hole is provided on the side wall of the furnace body, a second through hole is provided on the side wall of the cover body, the rotating part is passed through the first through hole and the second through hole, a part of the anti-friction part is located in the second through hole, and the other part is located between the cover body and the furnace body.

[0011] In this embodiment, the rotating member is inserted through the first through-hole of the furnace body and the second through-hole of the cover, achieving a rotatable connection between the cover and the furnace body. Part of the anti-friction member is disposed within the second through-hole, while the remaining part is located between the cover and the furnace body. This prevents direct friction between the rotating member and the cover, while also securing the anti-friction member and preventing movement.

[0012] In some embodiments, optionally, the anti-friction part includes: a first sleeve; a second sleeve, the second sleeve is located at one end of the first sleeve, the first sleeve and the second sleeve are both sleeved on the rotating part, the first sleeve is located in the second through hole, the second sleeve is located between the furnace body and the cover body, and the diameter of the outer wall of the second sleeve is larger than the diameter of the outer wall of the first sleeve.

[0013] In this embodiment, the anti-friction member includes a first sleeve and a second sleeve. The second sleeve is disposed at one end of the first sleeve, and both sleeves are sleeved outside the rotating member, thereby achieving installation of the anti-friction member. The first sleeve is located within the second through-hole, thereby securing the anti-friction member relative to the cover. The second sleeve is located between the cover and the furnace body, thereby isolating the cover and the furnace body. Furthermore, the outer wall of the second sleeve has a larger diameter than that of the first sleeve, thereby abutting the second sleeve between the furnace body and the cover. This prevents the anti-friction member from moving along the axis of the rotating member, thereby ensuring the reliability of the second sleeve in isolating the cover and the furnace body.

[0014] In some embodiments, optionally, the cover is located outside the furnace body, a sink is provided on the side wall of the furnace body, the sink is recessed toward the outside of the furnace body, the first through hole is provided in the sink, and the sink contacts the anti-friction member.

[0015] In this embodiment, a sink is provided on the side wall of the furnace body, which is recessed toward the outside of the furnace body, thereby forming a bulge on the outside of the furnace body. A first through hole is provided on the sink, and the sink is in contact with the anti-friction part, that is, the part of the furnace body that bulges outward is in contact with the anti-friction part, thereby reducing the contact area between the furnace body and the anti-friction part, reducing the friction area between the furnace body and the anti-friction part, thereby reducing the wear of the anti-friction part, and reducing the friction noise.

[0016] In some embodiments, optionally, the cover body is provided with a flange, and a portion of the anti-friction member located between the cover body and the furnace body is in contact with the flange.

[0017] In this embodiment, the anti-friction member contacts the flange on the cover body, which can effectively reduce the contact area between the cover body and the anti-friction member, thereby reducing the wear of the anti-friction member when the anti-friction member moves relative to the cover body.

[0018] In some embodiments, optionally, a flange is provided around the second through hole.

[0019] In this embodiment, the flange is provided around the second through hole, so that the flange can be manufactured together with the second through hole. For example, if the second through hole is a flange hole, the second through hole and the flange are formed together, which reduces the number of processing steps. At the same time, the provision of the flange also strengthens the strength of the cover at the second through hole.

[0020] In some embodiments, optionally, a convex rib is provided on a side of the anti-friction member facing the furnace body, and the anti-friction member contacts the outer side wall of the furnace body through the convex rib.

[0021] In this embodiment, a convex rib is provided on the side of the anti-friction member facing the furnace body, and the convex rib contacts the furnace body, thereby reducing the contact area between the furnace body and the anti-friction member, reducing the loss of the anti-friction member, and reducing the noise during the opening and closing process of the cover.

[0022] In some embodiments, optionally, there are multiple ribs, and the multiple ribs are spaced apart along the circumference of the anti-friction member; or the ribs are annular along the circumference of the anti-friction member.

[0023] In this embodiment, when there are multiple ribs, spaced apart along the circumference of the anti-friction member, the contact area between the anti-friction member and the furnace body is further reduced. This reduces wear on the anti-friction member and reduces noise during the opening and closing of the lid. When the ribs are annular, the manufacturing difficulty of the anti-friction member is reduced.

[0024] In some embodiments, optionally, the anti-friction component includes any one of the following: a plastic component, a rubber component, and a silicone component; and / or the furnace body includes a sheet metal component, and the cover body includes a sheet metal component.

[0025] In this embodiment, the anti-friction member comprises any one of a plastic member, a rubber member, and a silicone member; and / or the furnace body comprises a sheet metal member, and the cover body comprises a sheet metal member. Thus, the anti-friction member can reduce friction noise between the cover body and the furnace body.

[0026] In some embodiments, optionally, the cooking appliance further includes: a grill, disposed in the furnace body, the grill being used to carry food; and a heat preservation net, disposed in the furnace body, the heat preservation net being located on top of the grill.

[0041] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0042] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0043] Refer to the following Figures 4 to 7 The present invention describes a cooking appliance according to some embodiments of the present invention.

[0044] like Figure 4 、 Figure 5 and Figure 6 As shown, according to one embodiment of the present invention, a cooking appliance is provided, comprising: a stove body 1, a lid 2, and an anti-friction member 3. The stove body 1 is provided with an opening 10; the lid 2 is disposed on the stove body 1 and is rotatably connected to the side wall of the stove body 1 to open or close the opening 10; at least a portion of the anti-friction member 3 is disposed between the lid 2 and the stove body 1, and the lid 2 contacts the side wall of the stove body 1 through the anti-friction member 3.

[0045] The cooking device provided by the present invention includes a stove body 1, a lid 2, and an anti-friction member 3. The stove body 1 is provided with an opening 10. The lid 2 is mounted on the stove body 1 and is rotatably connected to the side wall of the stove body 1, thereby realizing the opening and closing of the opening 10. At least a portion of the anti-friction member 3 is disposed between the lid 2 and the stove body 1, so that the lid 2 contacts the stove body 1 through the anti-friction member 3. During the rotation of the lid 2, the lid 2 does not directly rub against the stove body 1, thereby preventing the occurrence of friction noise during the opening and closing of the lid 2.

[0046] It can be understood that the anti-friction member 3 can prevent friction between the cover body 2 and the furnace body 1. Specifically, the setting of the anti-friction member 3, on the one hand, creates a gap between the cover body 2 and the furnace body 1 to avoid direct contact between the cover body 2 and the furnace body 1. On the other hand, when relative friction occurs between the anti-friction member 3 and the cover body 2 or the furnace body 1, no abnormal sound will be generated, thereby ensuring that no abnormal noise is generated during the opening and closing process of the cover body 2.

[0047] It can be understood that the cover 2 and the furnace body 1 are both metal parts. Optionally, the cover 2 and the furnace body 1 are both sheet metal parts, and the anti-friction part 3 can be made of plastic or rubber.

[0048] Optionally, during the opening and closing process of the cover 2 , the anti-friction member 3 is relatively fixed to the furnace body 1 and rubs against the cover 2 ; or the anti-friction member 3 is relatively fixed to the cover 2 and rubs against the furnace body 1 .

[0049] like Figure 5 and Figure 6 As shown, in some embodiments, optionally, the cooking utensil further includes: a rotating member 4, which is passed through the furnace body 1 and the cover body 2, the cover body 2 is rotatably connected to the furnace body 1 through the rotating member 4, and the anti-friction member 3 is sleeved on the outside of the rotating member 4.

[0050] In this embodiment, the cooking utensil also includes a rotating part 4, and the cover body 2 is rotatably connected to the furnace body 1 through the rotating part 4, wherein the anti-friction part 3 is sleeved on the outside of the rotating part 4, thereby realizing the installation of the anti-friction part 3. There is no need to add other connecting structures to realize the installation of the anti-friction part 3, which reduces the use of parts and reduces costs, and also reduces the possibility of the anti-friction part 3 falling off.

[0051] Optionally, the rotating member 4 includes a rotating shaft.

[0052] Optionally, the rotating member 4 includes a rivet bolt, and the cooking appliance further includes a rivet nut, which is screwed together with the rivet bolt to achieve a rotational connection between the cover body 2 and the furnace body 1.

[0053] like Figure 5 and Figure 6 As shown, in some embodiments, optionally, a first through hole 12 is provided on the side wall of the furnace body 1, a second through hole 20 is provided on the side wall of the cover body 2, the rotating part 4 is passed through the first through hole 12 and the second through hole 20, a part of the anti-friction part 3 is located in the second through hole 20, and the other part is located between the cover body 2 and the furnace body 1.

[0054] In this embodiment, the rotating member 4 is disposed within the first through hole 12 of the furnace body 1 and the second through hole 20 of the cover 2, thereby achieving a rotational connection between the cover 2 and the furnace body 1. A portion of the anti-friction member 3 is disposed within the second through hole 20, while the remaining portion is located between the cover 2 and the furnace body 1. This prevents direct friction between the rotating member 4 and the cover 2 while also securing the anti-friction member 3 and preventing movement.

[0055] like Figure 7 As shown, in some embodiments, optionally, the anti-friction member 3 includes: a first sleeve 32; a second sleeve 34, the second sleeve 34 is located at one end of the first sleeve 32, the first sleeve 32 and the second sleeve 34 are both sleeved on the rotating member 4, the first sleeve 32 is located in the second through hole 20, the second sleeve 34 is located between the furnace body 1 and the cover body 2, and the diameter of the outer wall of the second sleeve 34 is larger than the diameter of the outer wall of the first sleeve 32.

[0056] In this embodiment, the anti-friction member 3 includes a first sleeve 32 and a second sleeve 34. The second sleeve 34 is disposed at one end of the first sleeve 32, and both sleeves are sleeved on the outside of the rotating member 4, thereby achieving the installation of the anti-friction member 3. The first sleeve 32 is located within the second through-hole 20, thereby fixing the anti-friction member 3 relative to the cover 2. The second sleeve 34 is located between the cover 2 and the furnace body 1, thereby achieving isolation between the cover 2 and the furnace body 1. Furthermore, the outer wall diameter of the second sleeve 34 is greater than that of the first sleeve 32, thereby allowing the second sleeve 34 to abut between the furnace body 1 and the cover 2, preventing the anti-friction member 3 from moving along the axis of the rotating member 4 and ensuring the reliability of the second sleeve 34 in isolating the cover 2 and the furnace body 1.

[0057] Optionally, the first sleeve 32 and the second sleeve 34 are coaxially arranged.

[0058] Optionally, the first sleeve 32 and the second sleeve 34 are an integral structure.

[0059] like Figure 5 and Figure 6 As shown, in some embodiments, optionally, the cover body 2 is located on the outside of the furnace body 1, and the side wall of the furnace body 1 is provided with a sinking platform 14, which is recessed toward the outside of the furnace body 1, and the first through hole 12 is provided on the sinking platform 14, which is in contact with the anti-friction part 3.

[0060] In this embodiment, a sink 14 is provided on the side wall of the furnace body 1, and the sink 14 is recessed toward the outside of the furnace body 1, thereby forming a bulge on the outside of the furnace body 1. The first through hole 12 is provided on the sink 14, and the sink 14 is in contact with the anti-friction part 3, that is, the part of the furnace body 1 that protrudes toward the outside is in contact with the anti-friction part 3, thereby reducing the contact area between the furnace body 1 and the anti-friction part 3, reducing the friction area between the furnace body 1 and the anti-friction part 3, thereby reducing the wear of the anti-friction part 3 and reducing the friction noise.

[0061] It is understandable that the cover 2 is located outside the furnace body 1 , and thus the anti-friction member 3 is located outside the furnace body 1 , so that at least a portion of the anti-friction member 3 is located between the furnace body 1 and the cover 2 .

[0062] In some embodiments, optionally, the cover body 2 is provided with a flange 22 , and a portion of the anti-friction member 3 located between the cover body 2 and the furnace body 1 is in contact with the flange 22 .

[0063] In this embodiment, the anti-friction member 3 contacts the flange 22 on the cover body 2, which can effectively reduce the contact area between the cover body 2 and the anti-friction member 3, thereby reducing the wear of the anti-friction member 3 when the anti-friction member 3 moves relative to the cover body 2.

[0064] In some embodiments, optionally, the flange 22 is disposed around the second through hole 20 .

[0065] In this embodiment, the flange 22 is disposed around the second through hole 20, allowing the flange 22 to be manufactured simultaneously with the second through hole 20. For example, if the second through hole 20 is a flanged hole, the second through hole 20 and the flange 22 can be formed simultaneously, thus reducing the number of manufacturing steps. Furthermore, the provision of the flange 22 also strengthens the strength of the cover 2 at the second through hole 20.

[0066] like Figure 7 As shown, in some embodiments, optionally, a convex rib 30 is provided on the side of the anti-friction member 3 facing the furnace body 1 , and the anti-friction member 3 contacts the outer side wall of the furnace body 1 through the convex rib 30 .

[0067] In this embodiment, a convex rib 30 is provided on the side of the anti-friction part 3 facing the furnace body 1. The convex rib 30 contacts the furnace body 1, thereby reducing the contact area between the furnace body 1 and the anti-friction part 3, reducing the loss of the anti-friction part 3, and reducing the noise during the opening and closing process of the cover body 2.

[0068] Optionally, the rib 30 is provided on a side of the second sleeve 34 that faces the furnace body 1 in the axial direction.

[0069] In some embodiments, optionally, there are multiple ribs 30 , and the multiple ribs 30 are spaced apart along the circumference of the anti-friction member 3 ; or the ribs 30 are annular along the circumference of the anti-friction member 3 .

[0070] In this embodiment, when there are multiple ribs 30, and when these ribs 30 are spaced apart along the circumference of the anti-friction member 3, the contact area between the anti-friction member 3 and the furnace body 1 is further reduced. This reduces wear on the anti-friction member 3 and also reduces noise during the opening and closing of the lid 2. When the ribs 30 are annular, the manufacturing difficulty of the anti-friction member 3 is reduced.

[0071] In some embodiments, optionally, the anti-friction component 3 includes any one of the following: a plastic component, a rubber component, and a silicone component; and / or the furnace body 1 includes a sheet metal component, and the cover body 2 includes a sheet metal component.

[0072] In this embodiment, the anti-friction member 3 comprises any one of a plastic member, a rubber member, and a silicone member; and / or the furnace body 1 comprises a sheet metal member, and the cover 2 comprises a sheet metal member. This allows the anti-friction member 3 to reduce abnormal friction noise between the cover 2 and the furnace body 1.

[0073] It can be understood that the anti-friction part 3 includes any one of a plastic part, a rubber part and a silicone part, so when the anti-friction part 3 rubs against the furnace body 1 or the cover body 2, no metal friction sound will be emitted, thereby reducing the noise during the process of the cover body 2 opening or closing the opening 10.

[0074] In some embodiments, optionally, the cooking appliance further includes: a grill, disposed in the furnace body 1, the grill being used to carry food; and a heat preservation net, disposed in the furnace body 1, the heat preservation net being located on top of the grill.

[0075] In this embodiment, the cooking utensil also includes a grill and a heat preservation net. The grill is arranged in the furnace body 1, and the heat preservation net is arranged in the furnace body 1 and located on the top of the grill, so that the hot air at the bottom of the grill can rise to the position of the heat preservation net to achieve the insulation of the food on the heat preservation net.

[0076] Optionally, the cooking appliance further includes a burner, which is disposed in the furnace body 1 , and the grill is disposed on the furnace body 1 and above the burner.

[0077] Optionally, the cooking appliance comprises a barbecue grill.

[0078] In a specific application, a sleeve (e.g., anti-friction member 3) passes through a flanged hole (e.g., second through-hole 20) in the side panel of the upper cover (e.g., cover body 2), and the upper cover's rotating shaft (e.g., rotating member 4) passes through both the flanged hole and the sleeve hole in the upper cover side panel. This solves the friction problem between the upper cover side panel and the side panel of the furnace body 1. The flanged edge 22 of the upper cover side panel contacts the sleeve (which is a plastic part), and the raised structure on the sleeve (e.g., rib 30) engages with the side panel of the furnace body 1, allowing the sleeve to transmit the friction, effectively solving the friction noise problem.

[0079] Optionally, the raised rib structure on the shaft sleeve slides with the side plate of the furnace body 1 , thereby reducing the noise caused by the friction between the flange 22 of the upper cover side plate and the side plate of the furnace body 1 .
