Description

Technical Field

[0001] This application relates to the field of cooking appliances technology, and in particular to a grill. Background Technology

[0002] A grill with a lifting lever has an upper grill pan assembly and a lifting lever rotatably connected, and the lifting lever and lower grill pan assembly are rotatably connected. The base of the lower grill pan assembly has a limiting groove, and the lifting lever has a limiting member that extends into the limiting groove. The limiting member's movement within the limiting groove restricts the range of rotation of the lifting lever relative to the lower grill pan assembly. Because the upper grill pan assembly is rotatably mounted on the lifting lever, the limiting member needs to withstand a significant pushing force when the upper grill pan assembly is opened. Therefore, the lifting lever of commercially available grills is usually made of die-cast aluminum to ensure that the limiting member can withstand the enormous pressure. However, the material and processing costs of die-cast aluminum are high, leading to a significant increase in the production cost of the grill. Utility Model Content

[0003] Therefore, it is necessary to provide a grilling machine that can greatly reduce production costs.

[0004] A grilling machine includes: a lower grilling pan assembly, an upper grilling pan assembly, and a lifting rod. The upper grilling pan assembly is rotatably connected to the lifting rod. The lower grilling pan assembly has a base. The end of the lifting rod is rotatably connected to the base via a pivot. The base has a limiting groove extending a predetermined length circumferentially along the pivot. The end of the lifting rod has a limiting member extending into the limiting groove and movable along the length direction of the limiting groove. The lifting rod is made of plastic, and the limiting member is made of metal.

[0005] The grilling machine provided in this application has a metal limiting component with high structural strength, which can meet the requirement of withstanding strong thrust when the upper grilling plate assembly is opened. At the same time, since the lifting rod is made of plastic, the material and manufacturing costs are greatly reduced compared to die-cast aluminum. This allows the grilling machine to greatly reduce production costs while meeting the lifting rod performance requirements, thereby effectively improving the market competitiveness of the grilling machine product.

[0006] In one embodiment, one end of the limiting member is embedded in the lifting rod.

[0007] This design eliminates the need for additional connecting and limiting components, resulting in a simpler structure and further reducing production costs.

[0008] In one embodiment, the limiting member is configured as a columnar rod, the length of the limiting member is L1, the length of the limiting member embedded in the lifting rod is L2, and L2 > 0.5L1.

[0009] This design ensures that the limiting component and the lifting rod have sufficient connection strength, reducing the possibility of the limiting component falling off, thus helping to extend the service life of the grill.

[0010] In one embodiment, the length L1 of the limiting member is 20mm~25mm.

[0011] This design ensures that the limiting component has sufficient length to be embedded in the lifting rod, and also has sufficient length to cooperate with the limiting groove, preventing the limiting component from coming out of the limiting groove, thereby ensuring the stability of the rotation angle locking of the lifting rod and the base.

[0012] In one embodiment, the cross-sectional area of ​​the limiting member is 7 mm. 2 ~13mm 2 .

[0013] In this way, sufficient structural strength of the limiting component is ensured without increasing costs.

[0014] In one embodiment, the limiting member is embedded in the lifting rod by an insert injection molding process.

[0015] Insert injection molding is a mature and easy-to-process technology that produces strong connections in the finished product and simplifies the assembly process.

[0016] In one embodiment, the limiting member is embedded in the lifting rod by a hot-pressing process.

[0017] In this way, the limiting component is embedded into the lifting rod through a hot pressing process, which reduces the requirements for the injection mold and helps to reduce production costs.

[0018] In one embodiment, the limiting member is made of stainless steel.

[0019] Stainless steel has high structural strength and is inexpensive, which helps to further control production costs.

[0020] In one embodiment, the limiting member is connected to the lifting rod by a fastener.

[0021] In this way, the lifting rod is easier to manufacture, and by connecting the limiting component and the lifting rod with fasteners, only the limiting component needs to be replaced if it is damaged.

[0022] In one embodiment, the limiting member is die-cast aluminum.

[0023] Thus, using die-cast aluminum to manufacture limiting parts is easy to form and simple to process.

[0024] In one embodiment, the lifting rod is made of bakelite, PA, or PBT.

[0025] Bakelite, PA, or PBT have excellent physical properties and are inexpensive, allowing for significant cost control while maintaining good lifting performance. Attached Figure Description

[0034] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0035] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected to" another component, it can be directly connected to the other component or there may be an intermediate component present. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application's specification are for illustrative purposes only and do not represent the only possible implementation.

[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0037] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature and the second feature are in indirect contact through an intermediate medium. Furthermore, "above," "over," and "on top" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0039] Please see Figures 1 to 6This application provides a grill, including: a lower grill pan assembly 10, an upper grill pan assembly 20, and a lifting rod 30. The upper grill pan assembly 20 is rotatably connected to the lifting rod 30. The lower grill pan assembly 10 has a base 11, and the end of the lifting rod 30 is rotatably connected to the base 11 via a rotating shaft 31. The base 11 has a limiting groove 111 extending a predetermined length circumferentially along the rotating shaft 31. The end of the lifting rod 30 has a limiting member 40, which extends into the limiting groove 111 and can move along the length direction of the limiting groove 111. Thus, by limiting the range of motion of the limiting member 40 through the limiting groove 111, the rotation angle of the lifting rod 30 relative to the base 11 can be limited. The lifting rod 30 is made of plastic, and the limiting member 40 is made of metal. Thus, the limiting component 40 is made of metal, which has high structural strength and can meet the requirement of withstanding strong thrust when the upper baking pan assembly 20 is opened. At the same time, since the lifting rod 30 is made of plastic, the material cost and manufacturing cost are greatly reduced compared to die-cast aluminum. This allows the grill to greatly reduce the production cost while meeting the performance requirements of the lifting rod 30, thereby effectively improving the market competitiveness of the grill product.

[0040] Furthermore, the lifting lever 30 is made of bakelite, PA (polyamide), or PBT (polybutylene terephthalate). These materials offer excellent physical properties and are inexpensive, allowing for significant cost control while maintaining the performance of the lifting lever 30. Of course, the lifting lever 30 can also be made of other plastics.

[0041] like Figures 2 to 6 As shown, in one embodiment, one end of the limiting member 40 is embedded within the lifting rod 30. This eliminates the need for an additional structure connecting the limiting member 40, resulting in a simpler structure and further reducing production costs.

[0042] Further, please see Figure 6 The limiting member 40 is configured as a columnar rod with a length of L1. The length of the limiting member 40 embedded in the lifting rod 30 is L2, where L2 ≥ 0.5L1. This ensures sufficient connection strength between the limiting member 40 and the lifting rod 30, reducing the possibility of the limiting member 40 falling off and thus helping to extend the service life of the grill.

[0043] Further, please see Figure 6The length L1 of the limiting member 40 is 20mm to 25mm. This ensures that the limiting member 40 has sufficient length to embed into the lifting rod 30, and also sufficient length to cooperate with the limiting groove 111, preventing the limiting member 40 from dislodging from the limiting groove 111, thereby ensuring the stability of the rotation angle locking between the lifting rod 30 and the base 11. Specifically, the length L1 of the limiting member 40 can be 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, or any other value within the range of 20mm to 25mm; this application does not impose any limitation on this.

[0044] In this embodiment, the cross-sectional area of ​​the limiting member 40 is 7mm. 2 ~13mm 2 If the cross-sectional area of ​​the limiting member 40 is too small, its strength will be insufficient and it will easily break. If the cross-sectional area of ​​the limiting member 40 is too large, a larger lifting rod 30 will be required, thus increasing costs. In this embodiment, the cross-sectional area of ​​the limiting member 40 is 7mm. 2 ~13mm 2 This design ensures sufficient structural strength for the limiting component 40 without increasing costs. Specifically, the cross-sectional area of ​​the limiting component 40 can be 7mm². 2 8mm 2 9mm 2 10mm 2 11mm 2 12mm 2 13mm 2 or at 7mm 2 ~13mm 2 This application does not limit any other value within the range.

[0045] like Figure 5 As shown, in this embodiment, the cross-section of the limiting member 40 is circular, but it is not limited to this. The cross-section of the limiting member 40 can also be square, hexagonal, octagonal, elliptical or other shapes.

[0046] Furthermore, the limiting component 40 is made of stainless steel. Stainless steel has high structural strength and is inexpensive, which helps to further control production costs. However, it is not limited to this; the limiting component 40 can also be made of other metal materials, such as copper.

[0047] In one embodiment, the limiting member 40 can be embedded into the lifting rod 30 using an insert injection molding process. That is, during the production of the lifting rod 30, the limiting member 40 is first installed in the injection mold, and then molten plastic is injected, so that the limiting member 40 and the lifting rod 30 are firmly joined together. The insert injection molding process is a mature and easy-to-process technology, and the finished product has a firm connection, which can also simplify the assembly steps.

[0048] However, this is not the only option. In another embodiment, the limiting member 40 can be embedded into the lifting rod 30 via a hot-pressing process. Specifically, the lifting rod 30 can be first injection molded from plastic. While the plastic is hot, the limiting member 40 is pressed into the plastic. After the plastic cools, one end of the limiting member 40 can be firmly embedded into the lifting rod 30. Embedding the limiting member 40 into the lifting rod 30 via a hot-pressing process requires less stringent injection mold requirements, which helps reduce production costs.

[0049] Furthermore, the surface of the limiting member 40 may be provided with grooves, barbs, holes, knurling, protrusions, etc., to increase the contact area between the limiting member 40 and the plastic, so that the limiting member 40 and the lifting rod 30 can be tightly joined after the plastic cools down, thereby preventing the limiting member 40 from falling off the lifting rod 30.

[0050] In the above embodiments, the limiting member 40 is directly embedded within the lifting rod 30, eliminating the need for a separate connecting structure, resulting in a very simple structure. However, this is not the only possibility. In other embodiments (not shown), the limiting member can also be connected to the lifting rod via fasteners. This simplifies the manufacturing of the lifting rod, and by connecting the limiting member and the lifting rod with fasteners, only the limiting member needs to be replaced if it is damaged.

[0051] Furthermore, the limiting component can be made of die-cast aluminum. Therefore, using die-cast aluminum to manufacture the limiting component makes it easy to form and simple to process. In this embodiment, the limiting component can be a column or a block, such as a cube or a sector-shaped block; this application does not impose any limitations on this.

[0052] like Figure 1 As shown, in this grill, there are two lifting levers 30, which are located on opposite sides of the upper grill plate assembly 20. A handle 50 is connected between the two lifting levers 30. During use, the user can open or close the upper grill plate assembly 20 by holding the handle 50. It is understood that the handle 50 and the two lifting levers 30 can be connected by fasteners or by snap-fit, and this application does not impose any restrictions on this.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
