Description

Technical Field

[0001] The utility model relates to the technical field of cooking equipment, in particular to a bearing component and cooking equipment. Background Art

[0002] At present, ovens or microwave ovens generally have a baking tray / grill, which is installed through the slide rails protruding from the left and right side walls of the oven or microwave oven cavity. Since the oven or microwave oven cavity and the baking tray / grill are metal structures, when the baking tray / grill is pulled out, the baking tray / grill and the cavity will generate friction vibration during the relative sliding process, thereby generating a "creaking" harsh noise, which makes people feel uncomfortable. In addition, after the baking tray / grill is taken out and put in many times over a long period of time, the side wall of the baking tray / grill is easy to scratch the inner wall surface of the cavity, causing the baking tray / grill or the cavity wall surface to wear and fall off.

[0003] Therefore, how to design a bearing assembly that can reduce the harsh sound generated when the grill pan / grill is pulled out and increase the service life of the equipment has become an urgent problem to be solved. Utility Model Content

[0004] The utility model aims at least to solve the problems of harsh sound generated when the grill pan / grill is pulled out and short service life of the equipment.

[0005] To this end, a first aspect of the utility model provides a bearing assembly.

[0006] A second aspect of the present invention provides a cooking device.

[0007] In view of this, the first aspect of the utility model proposes a supporting assembly for a cooking device, the cooking device including a cooking cavity, the supporting assembly including: a supporting body, the supporting body including a first end and a second end arranged opposite to each other, at least one mounting protrusion being respectively arranged on the first end and the second end; at least two plastic parts, the plastic parts including a receiving groove, at least two plastic parts being respectively covered and mounted on the first end and the second end of the supporting body through the receiving groove; a limiting portion, arranged at the notch of the receiving groove, for limiting the mounting protrusion within the receiving groove.

[0008] The bearing assembly provided by the utility model can be used in a cooking device, and the cooking device includes a cooking cavity, so that the bearing assembly can be arranged in the cooking cavity to carry food for cooking. Specifically, the bearing assembly includes a bearing, at least two plastic parts and a limiter. The bearing includes a first end and a second end arranged opposite to each other, and at least one mounting protrusion is respectively arranged on the first end and the second end, so that the mounting protrusion can be extended into the receiving groove of the plastic part, and the first end and the second end of the bearing are covered with the plastic part, so that when the bearing assembly is arranged in the cooking cavity, the plastic parts at the first end and the second end can be used to contact the cooking cavity, thereby avoiding direct contact between the bearing and the cooking cavity, so that the bearing can be prevented from scratching the cooking cavity when the bearing is taken in and placed. It can be understood that the material of the bearing and the cooking cavity is generally metal material, and the friction coefficient of the metal material is relatively large, so when the bearing assembly is pulled out, it will produce friction with the cooking cavity, thereby producing harsh noise. The present application separates the carrier from the cooking cavity by setting a plastic part, and utilizes the contact and sliding between the plastic part and the cooking cavity, thereby avoiding the generation of harsh noises and improving the user experience.

[0009] At the same time, by providing a limiting portion to limit the installation protrusion in the accommodating groove, the plastic component can be more firmly fixed on the carrier, thereby improving the overall stability of the carrier assembly.

[0013] In some embodiments, optionally, the mounting protrusion is disposed at the top and / or bottom of the edge of the first end or the second end.

[0014] In this embodiment, the mounting protrusion can be arranged at the top and / or bottom of the edges of the first end and the second end, that is, the mounting protrusion is arranged on the edges of the first end and the second end, and is arranged on the upper surface and / or the lower surface along the thickness direction of the carrier, which is conducive to cooperation with the accommodating groove and facilitates the installation of the plastic part.

[0015] In some embodiments, optionally, there are multiple limiting portions, and the multiple limiting portions are arranged at intervals from each other.

[0016] In this embodiment, the number of the limiting parts can be set to multiple, and the multiple limiting parts can be arranged at intervals, so that the multiple limiting parts can be used for limiting, which improves the stability of the installation of the plastic part and is also beneficial to the assembly of the plastic part and the carrier.

[0020] In this embodiment, the plastic part further includes a guide surface. The guide surface is arranged on the limiting portion and is arranged close to the surface of the carrier. The guide surface is arranged to be gradually inclined toward the inside of the receiving groove along the depth direction of the receiving groove. In this arrangement, the opening of the receiving groove is increasingly larger from the inside to the outside by arranging the guide surface, so that when assembling the carrier and the plastic part, the mounting protrusion can be more easily installed in the receiving groove, thereby improving the assembly efficiency.

[0021] In some embodiments, optionally, the guide surface includes one or a combination of a guide plane and a guide arc surface.

[0022] In this embodiment, the guide surface includes one or a combination of a guide plane and a guide cambered surface. In this arrangement, the guide surface can be arranged as a guide plane or a guide cambered surface, or a combination of the two, so that different guide structures can be arranged according to the actual structure.

[0023] In some embodiments, optionally, the plastic part further includes: a sliding boss, which is disposed on the limiting portion and away from the surface of the carrier, and is used to contact and slide with the cooking cavity.

[0024] In this embodiment, the plastic part further includes a sliding boss. The sliding boss is disposed on the limiting portion and is disposed away from the surface of the carrier, and is used to contact and slide with the cooking cavity. In this arrangement, by providing the sliding boss, the sliding boss is directly in contact with the cooking cavity, thereby reducing the contact area between the plastic part and the cooking cavity, so that the sliding boss can be used to reduce the friction between the plastic part and the cooking cavity, thereby further reducing abnormal noise.

[0025] In some embodiments, optionally, the number of sliding bosses corresponds one to one with the number of limiting portions.

[0026] In this embodiment, the number of the sliding bosses corresponds to the number of the limiting parts. This arrangement allows the number of the sliding bosses to correspond to the number of the limiting parts, so that the sliding bosses can be arranged at intervals, which can not only improve the stability of the bearing assembly when in use, but also reduce the friction between the bearing assembly and the cooking cavity.

[0062] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0063] 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 protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0064] Refer to the following Figures 1 to 21 The present invention describes a carrying assembly and a cooking device according to some embodiments of the present invention.

[0065] According to an embodiment of the first aspect of the present utility model, Figures 1 to 21 As shown, the first aspect of the utility model proposes a bearing assembly 1 for a cooking device, the cooking device comprising a cooking cavity 22, the bearing assembly 1 comprising a bearing body 10, at least two plastic parts 12 and a limiting portion 14. The bearing body 10 comprises a first end and a second end arranged opposite to each other, and at least one mounting protrusion 100 is respectively arranged on the first end and the second end. At least two plastic parts 12, the plastic parts 12 comprise a receiving groove 120, and at least two plastic parts 12 are respectively covered and installed on the first end and the second end of the bearing body 10 through the receiving groove 120. The limiting portion 14 is arranged at the notch of the receiving groove 120, and is used to limit the mounting protrusion 100 in the receiving groove.

[0066] The support assembly 1 provided by the utility model can be used in a cooking device, and the cooking device includes a cooking cavity 22, so that the support assembly 1 can be arranged in the cooking cavity 22 to support food for cooking. Specifically, the support assembly 1 includes a support body 10, at least two plastic parts 12 and a limiting portion 14. Figure 4 , Figure 5 , Fig.14 and Fig.15As shown, the carrier 10 includes a first end and a second end that are arranged opposite to each other, and at least one mounting protrusion 100 is respectively arranged on the first end and the second end, so that the mounting protrusion 100 can be extended into the receiving groove 120 of the plastic part 12, and the first end and the second end of the carrier 10 are covered by the plastic part 12. In this way, when the carrier assembly 1 is arranged in the cooking cavity 22, the plastic parts 12 at the first end and the second end can be used to contact the cooking cavity 22, thereby avoiding direct contact between the carrier 10 and the cooking cavity 22, thereby preventing the carrier 10 from scratching the cooking cavity 22 when taking and placing the carrier 10. It is understandable that the material of the carrier 10 and the cooking cavity 22 is generally metal, and the friction coefficient of metal is relatively large. Therefore, when the carrier component 1 is pulled out, it will rub against the cooking cavity 22, thereby generating harsh noises. Moreover, if it is taken in and out for a long time and many times, the side wall of the carrier component 1 is easy to scrape against the inner wall of the cooking cavity 22, thereby causing the carrier component 1 or the wall of the cooking cavity 22 to wear and fall off (products with enamel and ceramic on the inner wall of the carrier component 1 and the cooking cavity 22 will wear and even damage the enamel or ceramic coating). However, the present application separates the carrier 10 from the cooking cavity 22 by setting a plastic part 12, and uses the plastic part 12 to slide in contact with the cooking cavity 22, thereby avoiding the generation of harsh noises and preventing scratches between the carrier component 1 and the cooking cavity 22, thereby improving the user experience.

[0067] At the same time, by providing the limiting portion 14 to limit the installation protrusion 100 in the receiving groove, the plastic component 12 can be more firmly fixed on the carrier 10, thereby improving the overall stability of the carrier assembly 1.

[0068] In some embodiments, optionally, Figure 6 and Figure 7 As shown, the mounting protrusion 100 is a flange structure 1002 formed by bending the first end or the second end of the carrier 10 .

[0069] In this embodiment, the first end and the second end of the carrier 10 can be bent to form a flange structure 1002, and the flange structure 1002 is the mounting protrusion 100. This configuration does not require an additional protrusion to be separately provided, which saves materials, and because the flange structure 1002 and the carrier 10 are an integrated structure, they are relatively stable, which is conducive to improving the overall stability of the carrier assembly 1.

[0070] In some embodiments, optionally, Fig.16 and Fig.17 As shown, the mounting protrusion 100 is disposed at the top and / or bottom of the edge of the first end or the second end.

[0071] In this embodiment, the mounting protrusion 100 can be arranged at the top and / or bottom of the edges of the first end and the second end, that is, the mounting protrusion 100 is arranged at the edges of the first end and the second end, and is arranged on the upper surface and / or the lower surface along the thickness direction of the carrier 10, which is conducive to cooperation with the accommodating groove 120 and facilitates the installation of the plastic part 12.

[0072] In some embodiments, optionally, Figure 8 , Fig.10 , Fig.18 and Fig. 20 As shown, there are multiple limiting portions 14, and the multiple limiting portions 14 are arranged at intervals from each other.

[0073] In this embodiment, the number of the limiting parts 14 can be set to be multiple, and the multiple limiting parts 14 are arranged at intervals, so that the multiple limiting parts 14 can be used for limiting, which improves the stability of the installation of the plastic part 12 and is also beneficial to the assembly of the plastic part 12 and the carrier 10. At the same time, since the multiple limiting parts 14 are arranged at intervals, it is also possible to save the use of materials, thereby saving costs.

[0074] In some embodiments, optionally, the mounting protrusion 100 includes a plurality of mounting protrusions 100 , the plurality of mounting protrusions 100 are an integrated structure, and / or the plurality of mounting protrusions 100 are spaced apart along the edge of the carrier 10 .

[0075] In this embodiment, the mounting protrusions 100 may be provided in plurality, the plurality of mounting protrusions 100 are an integrated structure, and / or the plurality of mounting protrusions 100 are arranged at intervals along the edge of the carrier 10. This arrangement, by providing a plurality of mounting protrusions 100 and connecting them into an integrated structure, can improve the stability of the connection between the plastic part 12 and the carrier 10.

[0076] In some embodiments, optionally, Fig. 9 and Fig.19 As shown, the plastic part 12 further includes: a guide surface 122 disposed on the limiting portion 14 and close to the surface of the carrier 10 ; the guide surface 122 is gradually inclined toward the inside of the accommodating groove 120 along the depth direction of the accommodating groove 120 .

[0077] In this embodiment, the plastic part 12 further includes a guide surface 122. The guide surface 122 is disposed on the limiting portion 14 and is disposed close to the surface of the carrier 10. The guide surface 122 is gradually inclined toward the inside of the receiving groove 120 along the depth direction of the receiving groove 120. In this arrangement, the opening of the receiving groove 120 becomes larger from the inside to the outside by providing the guide surface 122, so that when the carrier 10 and the plastic part 12 are assembled, the mounting protrusion 100 can be more easily installed in the receiving groove 120, thereby improving the assembly efficiency.

[0078] In some embodiments, optionally, the guide surface 122 includes one or a combination of a guide plane surface and a guide arc surface.

[0079] In this embodiment, the guide surface 122 includes one or a combination of a guide plane and a guide cambered surface. In this configuration, the guide surface 122 can be configured as a guide plane or a guide cambered surface, or a combination of the two, so that different guide structures can be configured according to the actual structure.

[0080] In some embodiments, optionally, the plastic member 12 further includes: a sliding boss 124 , which is disposed on the limiting portion 14 and away from the surface of the carrier 10 , and is used to contact and slide with the cooking cavity 22 .

[0081] In this embodiment, the plastic part 12 further includes a sliding boss 124. The sliding boss 124 is disposed on the limiting portion 14 and is disposed away from the surface of the carrier 10, and is used to contact and slide with the cooking cavity 22. In this arrangement, by providing the sliding boss 124, the sliding boss 124 is directly in contact with the cooking cavity 22, thereby reducing the contact area between the plastic part 12 and the cooking cavity 22, so that the sliding boss 124 can be used to reduce the friction between the plastic part 12 and the cooking cavity 22, thereby further reducing abnormal noise.

[0082] In some embodiments, optionally, the number of the sliding bosses 124 corresponds to the number of the limiting portions 14 one by one.

[0083] In this embodiment, the number of the sliding bosses 124 corresponds to the number of the limiting portions 14. In this arrangement, the number of the sliding bosses 124 can be set to correspond to the number of the limiting portions 14, so that the sliding bosses 124 can also be arranged at intervals, which can not only improve the stability of the bearing assembly 1 when in use, but also reduce the friction between the bearing assembly 1 and the cooking cavity 22.

[0084] In some embodiments, optionally, the mounting protrusion 100 includes an arc-shaped mounting protrusion.

[0085] In this embodiment, the mounting protrusion 100 comprises an arc-shaped mounting protrusion. This arrangement, by setting the mounting protrusion 100 as an arc-shaped mounting protrusion, facilitates the sliding of the bearing assembly 1 in the cooking cavity 22, thereby improving the user's experience.

[0086] In some embodiments, optionally, Figure 2 , Figure 3 , Fig.12 and Fig.13 As shown, the carrier 10 is one of a baking tray 102 and a baking rack 104 or a combination thereof.

[0087] In this embodiment, the carrier 10 can be one of a baking tray 102 and a grill 104 or a combination thereof, and can be specifically configured according to the actual use requirements of the user and the cooking device 2 .

[0088] In some embodiments, optionally, the plastic part 12 includes: one of a polyimide plastic part, a polytetrafluoroethylene plastic part, a polyetherketone plastic part, and a polyethylene plastic part.

[0089] In this embodiment, the plastic part 12 includes one of a polyimide plastic part, a polytetrafluoroethylene plastic part, a polyetherketone plastic part, and a polyethylene plastic part. It is understandable that the plastic part 12 made of the above material is resistant to high temperature, corrosion, has high hardness and strength, is environmentally friendly and non-toxic, can contact food, and has less noise when rubbed with metal, so it is suitable for cooking equipment.

[0090] Among them, polyimide is a high-performance engineering plastic with a very low friction coefficient, so it makes less noise when rubbing against metal. In addition, polyimide has good high temperature resistance and corrosion resistance, performs well when used in high temperature and harsh environments, has high hardness and strength, and good wear resistance. It is environmentally friendly and non-toxic, can contact food, and is suitable for oven structural parts. Of course, the plastic part 12 of the present application is not limited to the above-mentioned types, and the plastic part 12 can also be other material structural parts that produce low friction vibration and low abnormal sound with metal.

[0091] In some embodiments, optionally, the inner surface of the cooking cavity 22 is provided with an enamel or ceramic coating.

[0092] In this embodiment, providing an enamel or ceramic coating can make the inner surface of the cavity more resistant to high temperatures, corrosion, scratches, easier to clean, and have a higher hardness.

[0093] In some embodiments, the surface of the carrier 10 is provided with an enamel or ceramic coating.

[0094] In this embodiment, the enamel or ceramic coating can make the surface of the carrier 10 more resistant to high temperature, corrosion, scratch, easy to clean, and have higher hardness.

[0095] In some embodiments, the carrier 10 comprises a metal carrier.

[0096] In some embodiments, cooking cavity 22 comprises a metal cooking cavity.

[0097] In some embodiments, the plastic member 12 optionally comprises a low friction rubber-like structure.

[0098] In some embodiments, optionally, the material of the cooking cavity 22 includes galvanized sheet, aluminum sheet, stainless steel, low carbon steel, etc.

[0099] In some embodiments, the inner surface of the cooking cavity 22 is optionally coated with an enamel or ceramic coating.

[0100] In this embodiment, by coating the inner surface of the cooking cavity 22 with enamel or ceramic coating, the inner surface of the cooking cavity 22 can be made more resistant to high temperatures, corrosion, scratches, easy to clean, and has a higher hardness.

[0101] In some embodiments, optionally, the material of the carrier 10 includes stainless steel, aluminum alloy, and aluminum-plated steel plate.

[0102] In some embodiments, optionally, the surface of the carrier 10 is sprayed with enamel or ceramic coating.

[0103] According to an embodiment of the first aspect of the present utility model, Figures 2 to 21 As shown, the first aspect of the present application is described by taking the baking tray 102 as an example of the bearing assembly 1. First, a polyimide plastic sliding structure is added to the left and right sides of the baking tray 102 to reduce abnormal noise and reduce wear on the cavity and the baking tray 102 surface.

[0104] The baking tray 102 and the baking tray plastic sliding structure are as follows Figures 2 to 11 As shown, the plastic sliding structure (plastic part 12) has an upper arc structure and an oblique convex structure (the upper arc structure is the guide surface 122, and the oblique surface of the oblique convex structure is the guide surface 122). When installing, the baking tray 102 is inserted into the plastic channel (accommodating groove 120) and fixed. The oblique convex structure (equivalent to the limiting part 14) can prevent the baking tray 102 from detaching from the plastic structure (plastic part 12). The convex sliding structure (sliding boss 124) on the plastic sliding structure is used to reduce the contact surface between the plastic part 12 and the metal slide rail 20 of the cavity, reduce friction, and thus reduce abnormal noise and cavity wear. The concave structure thereon (the concave structure formed between the multiple limiting parts 14 after the multiple limiting parts 14 are arranged at intervals) is to facilitate its easy fixing and installation on the baking tray 102 and to reduce material and save costs.

[0105] According to an embodiment of the first aspect of the present utility model, Figures 12 to 21 As shown, the first aspect of the present application is described by taking the grill 104 as an example of the bearing assembly 1. First, a polyimide plastic sliding structure is added to the left and right sides of the grill 104 to reduce abnormal noise and reduce wear on the cavity and the grill pan 102 surface.

[0106] like Figure 7 and Fig.17As shown, the two arc structures (guide surfaces 122) at the opening of the grill plastic sliding part are used to facilitate its fixed installation on the grill 104 (the cylindrical structure on the side of the grill 104 is inserted into the arc groove). After the installation is completed, the arc convex structure (limiting part 14) extending below the plastic part 12 prevents the grill 104 from sliding out. The convex sliding structure (sliding boss 124) thereon is used to reduce the contact surface between the plastic part 12 and the cavity metal slide rail 20, reduce friction, and thus reduce abnormal noise and wear. The concave structure thereon (the concave structure formed between the multiple limiting parts 14 after the multiple limiting parts 14 are arranged at intervals) is also to facilitate its easy fixed installation on the grill 104 and to reduce material and save costs.

[0107] The second aspect of the present invention provides a cooking device 2, comprising: a bearing assembly 1 as in any technical solution of the first aspect.

[0108] The cooking device 2 provided by the utility model includes the bearing assembly 1 in any technical solution of the first aspect. Since the cooking device 2 includes the bearing assembly 1 in any technical solution of the first aspect, the cooking device 2 provided by the present application also has all the beneficial technical effects of the bearing assembly 1 in any technical solution of the first aspect, which will not be repeated here.

[0109] In some embodiments, optionally, the cooking device 2 is one of a microwave oven and an oven.

[0110] In this embodiment, the cooking device 2 is a kind of microwave oven and oven. Of course, it can also be other types of cooking devices.

[0111] In some embodiments, optionally, slide rails 20 are provided on the left and right sides of the cooking cavity 22 of the microwave oven and / or oven, and the carrying assembly 1 can slide in cooperation with the slide rails 20 .

[0112] The following is an explanation of the reason why the relative friction between two metal parts produces abnormal noise: Since the cavity and the baking tray / grill are both made of metal, the friction coefficient is relatively large. When the baking tray / grill is pulled out, the friction vibration (stick-slip effect) between the two during the relative sliding process will cause a "squeaking" harsh abnormal noise, which makes people feel uncomfortable. (Sticky effect: When two contact surfaces slide, the surface will produce micro-deformation as the friction force fluctuates during the relative sliding process between the two contact surfaces. This deformation will store a certain amount of energy, which will release energy during the relative movement to produce pulse vibration, and finally produce friction noise.) In addition, after the baking tray is taken in and out for a long time and many times, the side wall of the baking tray / grill is easy to scratch the inner wall of the cavity, causing the baking tray / grill or the cavity wall to wear and fall off (for products with enamel and ceramics, the enamel or ceramic coating will be worn or even damaged).
