Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a detachable handle structure and cooking equipment. Background Technology

[0002] Handles are common components used to facilitate door opening and are widely used in various door structures, such as built-in ovens and refrigerators. Current handle designs typically employ an integrated structure with the door body, a design that presents significant drawbacks during maintenance. Because the handle is inseparable from the door body, maintenance requires disassembling the entire door. This is especially problematic for larger products like built-in ovens, where the disassembly and reassembly process is complex and time-consuming, causing considerable inconvenience to both users and maintenance personnel. Furthermore, built-in ovens need to be fully integrated into cabinets; disassembly is not only cumbersome but can also damage the cabinet structure. Therefore, a higher requirement is placed on the maintainability of components—that is, maintenance can be performed without removing the product.

[0003] In terms of transportation, the existing integrated handle design also has shortcomings. Since the handle is inseparable from the door body, the entire product needs to be protected during transportation, increasing the complexity and cost of packaging. Furthermore, the handle is easily damaged by impacts during transportation, further increasing the frequency and cost of after-sales maintenance.

[0004] In the prior art, for example, Chinese patent CN101033908A discloses a refrigerator door handle that uses a blind hole thread design. However, this design leads to uneven wall thickness of the handle seat, which can easily cause surface shrinkage problems in actual production, thus affecting the appearance quality. Since the handle seat is usually an important appearance component with high requirements for surface quality, this design defect limits its application in high-end products.

[0005] In summary, existing handle designs have significant shortcomings in terms of maintainability, transportability, and appearance quality, and there is an urgent need for an innovative design that can solve these problems. Utility Model Content

[0051] Reference Figures 1-11 This is one embodiment of the detachable handle structure of this utility model.

[0052] The detachable handle structure includes a door body 100, two mounting brackets 200, a handle assembly 300, and handle fastening screws 400.

[0053] The door 100 can be any type of door, such as a metal door, a wooden door, or a glass door. In this embodiment, a common household appliance door 100 is used, such as the glass door of an oven.

[0054] Two mounting brackets 200 are securely fixed to the front side of the door 100 using screws or other fixing methods. For example... Figure 6 As shown, each mounting bracket 200 has an upwardly protruding cylindrical structure 210, which has a through-hole 211 for connecting to the handle assembly 300. The wall of the fixing hole 211 can be internally threaded or smooth, and can be used with self-tapping screws.

[0055] The handle assembly 300 consists of a handle body 310 and two handle seats 320. The handle body 310 is the part the user actually grips and can be of various shapes and materials, such as stainless steel, plastic, or aluminum alloy. The two handle seats 320 are respectively fixed to both ends of the handle body 310, and can be secured by screws, clips, or adhesive. Figure 5 As shown, each handle base 320 is provided with a groove structure 321, the shape of which matches the cylindrical structure 210 on the mounting bracket 200. One end of the groove structure 321 is provided with a through hole 322 penetrating the handle base 320, and the other end is provided with a limiting groove 323. The through hole 322 and the limiting groove 323 are respectively opposite to the two ends of the fixing hole 211 of the cylindrical structure 210 of the mounting bracket 200. In this embodiment, the handle assembly 300 is placed horizontally, the bottom end of the groove structure 321 is provided with a through hole 322, and the top end is provided with a limiting groove 323.

[0056] like Figure 10 and Figure 11 As shown, the handle fastening screw 400 passes through the through hole 322 on the handle seat 320 and is threaded into the fixing hole 211 on the cylindrical structure 210 of the mounting bracket 200. Importantly, the length of the handle fastening screw 400 is greater than the length of the cylindrical structure 210, so that when the handle fastening screw 400 has completely passed through the fixing hole 211, its end will be inserted into the limiting groove 323 on the handle seat 320.

[0057] When installing the handle, first align the groove structure 321 on the handle seat 320 with the cylindrical structure 210 on the mounting bracket 200 and fit them together. Then, pass the handle fastening screw 400 from bottom to top through the through hole 322 on the handle seat 320 and screw it into the fixing hole 211 of the cylindrical structure 210 of the mounting bracket 200. Since the screw length is greater than the length of the fixing hole 211, when the screw is fully engaged with the fixing hole 211 and tightened further, the end of the screw will be squeezed into the limiting groove 323 on the handle seat 320, forming a certain plastic deformation or cutting on the plastic or metal material of the handle seat 320, thereby achieving double fixation. On the one hand, the threaded connection of the screw provides axial tightening force, pressing the handle seat 320 onto the mounting bracket 200; on the other hand, the squeezing and clamping action of the screw end in the limiting groove 323 further enhances the reliability of the connection and prevents the handle from loosening or falling off. When removing the handle, simply loosen the handle fastening screw 400; there is no need to disassemble the entire door body 100, which greatly simplifies the maintenance process and improves maintainability.

[0058] The aforementioned detachable handle structure, through its detachable design, allows the handle to be removed separately from the door body 100 without disassembling the entire door body 100. This greatly simplifies the maintenance process, improves product maintainability, and reduces maintenance costs and time. It also facilitates product transportation and packaging, reducing transportation costs and the risk of handle damage during transport. Furthermore, the engagement of the handle fastening screw 400 with the limiting groove 323 on the handle base 320 provides double fixation, enhancing the reliability of the connection between the handle base 320 and the mounting bracket 200, preventing the handle from loosening or falling off, improving product lifespan and safety, and enhancing surface quality while maintaining strength.

[0059] In this embodiment, see Figure 11 A guide structure 212 is provided at one end of the fixing hole 211 of the cylindrical structure 210 of the mounting bracket 200. This guide structure 212 can be in the form of a chamfer, a tapered hole, or a bevel, and its function is to guide the handle fastening screw 400 to more easily align and screw into the fixing hole 211. When installing the handle, because the guide structure 212 is provided at the entrance of the fixing hole 211, the handle fastening screw 400 is more easily aligned with the hole opening, avoiding misalignment or displacement of the screw during installation, thus improving installation efficiency and success rate.

[0060] like Figure 4 and Figure 5 As shown, handle seat fixing holes 324 are respectively provided on the handle seats 320 on both sides of the groove structure 321, and handle mounting holes 311 are provided on the handle body 310 at the corresponding positions of the handle seat fixing holes 324. Handle seat fastening screws 330 pass through the handle seat fixing holes 324 and handle mounting holes 311 to securely connect the handle seat 320 to the handle body 310. By adding handle seat fixing holes 324 and handle mounting holes 311, and using handle seat fastening screws 330 for connection, the connection between the handle seat 320 and the handle body 310 becomes more robust and reliable, effectively preventing the handle from loosening or shaking during use, and improving the stability and service life of the handle. Compared with traditional snap-fit ​​or adhesive methods, screw connections have higher strength and reliability, and are especially suitable for handle structures that withstand large tensile forces.

[0061] In this embodiment, the groove structure 321 extends through the handle base 320 from front to back. Designing the groove structure 321 to be continuous facilitates mold manufacturing and product molding, reducing production costs. The handle base 320 has several interlocking reinforcing ribs inside, which effectively improves the structural strength and rigidity of the handle base 320, preventing deformation or breakage during use. The effect of the reinforcing ribs is particularly pronounced when the handle is subjected to significant tensile force. The interlocking reinforcing ribs form a three-dimensional mesh structure, distributing external forces in various directions, thereby improving overall bending and torsional resistance.

[0062] In this embodiment, the handle fastening screw 400 is a self-tapping screw. Using a self-tapping screw eliminates the need for pre-tapping the mounting bracket 200, simplifying the installation process, improving production efficiency, and reducing manufacturing costs. During screwing in, the self-tapping screw's own threads can penetrate the material of the mounting bracket 200, forming a secure connection. The advantages of self-tapping screws are particularly evident when the mounting bracket 200 is made of plastic.

[0063] In this embodiment, a door trim strip 500 is also provided on the door body 100, such as... Figure 3 and Figure 8 As shown, the door trim 500 includes at least two side portions 510 respectively provided along both sides of the door body 100, with the side portions 510 partially located on the outer side of the door body 100 edge. Referring to the figure, the side portions 510 are connected into an integral structure by a middle portion 520 located at the lower part of the door body 100.

[0064] A door body mounting hole 110 is provided on the door body 100 located inside the door trim 500, and a trim mounting hole 511 is provided on the door trim 500 located outside the door body 100. A first mounting hole 220 and a second mounting hole 230 are provided on the mounting bracket 200 corresponding to the door body mounting hole 110 and the trim mounting hole 511, respectively.

[0065] A first bracket fastening screw (not shown) passes through the first mounting hole 220 and the door mounting hole 110 to fasten the mounting bracket 200 to the door 100. A second bracket fastening screw (not shown) passes through the second mounting hole 230 and the trim mounting hole 511 to fasten the mounting bracket 200 to the door trim 500.

[0066] The side 510 of the door trim 500 covers the edge of the door body 100, serving not only a protective and decorative function, but more importantly, it solves the special problem encountered in the installation of handles in products such as household ovens. The outer surface of most household ovens is made of tempered glass. For aesthetic and heat insulation reasons, tempered glass is difficult to process, and usually only simple round holes with a diameter of less than 15mm are machined at the handle connection point. However, to ensure sufficient connection strength, the size of the mounting bracket 200 often needs to be made larger, much larger than the size of the small hole pre-drilled in the glass.

[0067] Therefore, to ensure the stable installation of the mounting bracket 200 and avoid excessive damage to the fragile glass door, this embodiment specifically adds a door trim strip 500. The door trim strip 500 is made of sheet metal and has sufficient strength and rigidity to effectively withstand the fixing force of the mounting bracket 200. This avoids direct large-area or complex structural connections on the glass, ensuring both installation reliability and protection of the glass door.

[0068] Furthermore, the detachable handle structure also includes two fasteners 600. The two fasteners 600 are respectively disposed on the rear side of the door body 100 corresponding to the two mounting brackets 200. Mounting holes 610 are provided on the fasteners 600 corresponding to the door body mounting hole 110 and the trim mounting hole 511, for screwing in the first bracket fastening screw and the second bracket fastening screw.

[0069] By adding a fixing member 600 to the rear side of the door body 100, a "sandwich" fixing method is formed, which clamps the door body 100 between the mounting bracket 200 and the fixing member 600, greatly improving the firmness and stability of the installation. At the same time, the fixing member 600 can also disperse the tightening force of the screws, reduce the concentration of local stress on the door body 100, and further improve the reliability of the connection.

[0070] The fastener 600 is also provided with positioning posts 620, and positioning holes 512 / 240 are provided on the side 510 of the door trim 500 and the mounting bracket 200 corresponding to the positioning posts 620. By providing positioning posts 620 on the fastener 600 and providing positioning holes on the door trim 500 and the mounting bracket 200, precise alignment between the door trim 500 and the fastener 600 can be achieved, improving the accuracy and convenience of installation.

[0071] This utility model also includes a cooking device, such as an oven, microwave oven or steamer, on which the above-mentioned detachable handle structure is installed on the door 100.

[0072] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
