Description

Technical Field

[0001] This invention relates to the field of refrigeration technology, and in particular to a refrigerator. Background Technology

[0002] In the refrigerator industry, some refrigerators are equipped with door handles that protrude from the front surface of the door to facilitate opening and closing.

[0003] Currently, for refrigerators with door handles, the door handles are basically fixed by threaded handle bases pre-embedded in the foam layer of the door body. In order to increase the cabinet capacity and reduce logistics costs, the handles are usually not installed at the factory. After unpacking, the door handles are installed by after-sales personnel.

[0004] During production, the handle base is fixed to the inner side of the door using screws and a matching screwdriver. Then, foam is applied. After foaming, the screws are removed, and a corresponding handle cover is used to cover the corresponding holes on the door for the screws. During after-sales installation, the after-sales personnel remove the handle cover and then use bolts to fix the door handle and handle base to the door. In this production and installation method, the installation and removal of screws requires a significant amount of manpower and time, reducing production efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a refrigerator to improve production efficiency.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] According to one aspect of the present invention, a refrigerator is provided, comprising a cabinet and an openable door covering the cabinet. The door includes a door shell, a handle base, a handle cover, and a foam layer. A perforation is formed in the shell. A locking hole is formed on the front side of the handle base, and an internal thread is provided in the locking hole. The front side of the handle base is abutted against the inner side of the door shell, surrounding and closing the outer periphery of the perforation. The locking hole and the perforation are in communication. The handle cover includes a cover portion and a locking portion protruding from the cover portion. The locking portion passes through the perforation and the locking hole sequentially and is detachably locked within the locking hole. The cover portion abuts against the outer side of the door shell. The foam layer is disposed on the inner side of the door shell and covers the handle base.

[0008] In some embodiments, a limiting protrusion is provided on the outer periphery of the engaging portion, and the limiting protrusion elastically abuts against the inner peripheral wall of the engaging hole.

[0009] In some embodiments, a locking protrusion is provided on the inner peripheral wall of the locking hole; the limiting protrusion is located behind the locking protrusion and elastically abuts against the locking protrusion.

[0010] In some embodiments, the handle base includes a base body and a baffle; the engaging hole is disposed on the base body; and the baffle closes the rear end of the engaging hole.

[0011] In some embodiments, the baffle is provided with a connecting rib, which is detachably connected to the base.

[0012] In some embodiments, a cavity is formed within the engaging portion, making the engaging portion elastic and capable of stretching and contracting radially.

[0013] In some embodiments, the engaging portion includes two engaging arms with one end connected to the cover portion and a connecting arm connecting the other ends of the two engaging arms; the two engaging arms are spaced apart, and the cavity is formed between the two engaging arms; the engaging arms engage in the engaging hole.

[0014] In some embodiments, the outer periphery of the front end of the engaging portion and the perforation are interference-fitted.

[0015] In some embodiments, the handle seat further includes a nut, which is integrally injection molded into the engagement hole and has an internal thread formed in the engagement hole.

[0016] In some embodiments, the outer periphery of the handle seat is provided with a wing plate.

[0017] As can be seen from the above technical solution, the present invention has at least the following advantages and positive effects:

[0018] In this invention, the handle base is provided with a locking hole. Before the door body is foamed, the locking part of the handle cover passes through the perforation in the door shell and locks into the locking hole, with the cover part abutting against the outer side of the door shell, thereby limiting the handle base to the door shell, thus limiting and fixing the handle base. This facilitates the limiting of the handle base before the door body is foamed and seals the perforation in the door shell. After foaming, the handle cover is installed and transported together with the door shell. The handle cover is detachably locked into the locking hole. During after-sales installation, the handle cover is pulled out of the locking hole, and the bolts connect with the internal threads in the locking hole to fix the door handle to the door shell. By utilizing the detachable locking of the handle cover and handle base, the positioning and fixing of the handle base before foaming and the sealing of the perforation are achieved. The positioning of the handle cover and the sealing of the door shell do not require separate bolt installation or removal, simplifying the production process and improving production efficiency.

During after-sales installation, the after-sales personnel remove the handle cover and then use bolts to fix the door handle and handle base to the door. In this production and installation method, the installation and removal of screws requires a significant amount of manpower and time, reducing production efficiency.

[0031] Figure 1 This is a schematic diagram of the structure of an embodiment of the refrigerator of the present invention.

[0032] In this embodiment, with the refrigerator as a reference, the direction facing the inside of the refrigerator is called "inside," and the direction away from the inside of the refrigerator is called "outside."

[0033] See Figure 1 This embodiment provides a refrigerator, including a cabinet 100, a door 200, and a door handle 300. The cabinet 100 forms a refrigeration compartment with a front opening for storing items at low temperatures. The door 200 is an openable cover on the cabinet 100. When closed, the door 200 seals the opening of the refrigeration compartment, creating a closed environment. The door handle 300 opens or closes the door 200, allowing items to be placed or removed from the refrigeration compartment. The door handle 300 is installed on the door 200 to facilitate pushing and pulling the door, making it easier to open and close, and providing a better user experience.

[0034] In this embodiment, the door 200 is rotatably connected to the housing 100 to form a rotating door shell 210. The cooling compartment of the housing 100 is opened or closed by rotating the door 200.

[0035] In some embodiments, the door 200 is slidably connected to the box 100 to form a drawer-type door shell 210, and items can be taken out and put in the box 100 by sliding the door 200.

[0036] In this embodiment, the door handle 300 is disposed on the left and right sides of the door body 200. In some embodiments, the door handle may be disposed on the front of the door body 200.

[0037] Figure 2 This is a schematic diagram of the door of a refrigerator according to an embodiment of the present invention. Figure 3 This is an exploded structural diagram of the door of a refrigerator according to an embodiment of the present invention.

[0038] In this embodiment, the door body 200 includes a door shell 210, a handle base 220 disposed on the inner side of the door shell 210, and a handle cover 230 disposed on the outer side of the door shell 210. The door body 200 is foamed, and a foam layer is formed on the inner side of the door shell 210. The handle base 220 is disposed within the foam layer and covered by the foam layer. A hole is provided on the door shell 210 corresponding to the handle base 220. During the transportation of the refrigerator, the hole on the door shell 210 is sealed by the handle cover 230. After transportation to the destination, the handle cover 230 on the door shell 210 is removed. The door handle 300 is then connected to the handle base 220 after passing through the hole on the door shell 210 with a fastener, so as to fix the door handle 300 to the door shell 210. The door handle 300 and the handle base 220 are connected to install the door handle 300 on the door shell 210.

[0039] Figure 4 This is a cross-sectional structural diagram of the door of a refrigerator according to an embodiment of the present invention.

[0040] See Figure 4 In this embodiment, the handle cover 230 can be inserted into the handle base 220. Before the door body 200 is foamed, the handle base 220 is limited and fixed on the door shell 210, so that the handle base 220 is in a preset position on the rear side of the door shell 210 after the door body 200 is foamed, for connecting the door handle 300.

[0041] In this embodiment, the door shell 210 is rotatably connected to the housing 100, and a through hole 211 is provided on the door shell 210.

[0042] In this embodiment, the perforation 211 is circular in shape. In some embodiments, the perforation 211 is square or elliptical in shape, etc.

[0043] Figure 5 This is a schematic diagram of the handle base of an embodiment of the refrigerator of the present invention. Figure 6 This is a cross-sectional structural diagram of the handle base in an embodiment of the refrigerator of the present invention.

[0044] See Figures 2 to 6 Before the door body 200 is foamed, the handle base 220 is attached to the inner side of the door shell 210 and is locked in place by the handle cover 230. The front side of the handle base 220 is provided with a locking hole 229. The handle cover 230 can pass through the through hole 211 on the door shell 210 and extend into the locking hole 229, fixing the handle base 220 and limiting it to the inner side of the door shell 210.

[0045] In this embodiment, the handle base 220 includes a base body 221, a baffle 222, and a nut 223. The front side of the base body 221 is attached to the inner side of the door shell 210, and the engaging hole 229 is provided on the front side of the base body 221.

[0046] In this embodiment, the front side of the seat 221 is flat. After the front side of the seat 221 is attached to the inner side of the door shell 210, the engaging hole 229 and the through hole 211 are aligned and connected. The flat structure of the front side of the handle seat 220 surrounds and closes the outer periphery of the engaging hole 229 and the through hole 211. That is, after the front side of the seat 221 is attached to the inner side of the door shell 210, there is no gap between the front side of the seat 221 and the inner side of the door shell 210. During foaming, the foaming material will not enter the engaging hole 229 and the through hole 211 from the front side of the seat 221, effectively preventing the foaming material from clogging the engaging hole 229 or overflowing from the through hole 211 to the outer side of the door shell 210.

[0047] In some embodiments, an annular or circular blocking ring is formed on the front side of the seat 221 around the axis of the engaging hole 229. The blocking ring fits against the inner side of the door shell 210, thereby sealing the outer periphery of the engaging hole 229 and the through hole 211.

[0048] In this embodiment, the seat 221 has a length in one direction in the radial direction that is greater than the length in any other direction in the radial direction of the seat 221, thereby effectively preventing the seat 221 from rotating within the foam layer after foaming.

[0049] In this embodiment, a wing plate 2212 protrudes from the outer peripheral surface of the handle base 220. Specifically, the wing plate 2212 protrudes from the outer periphery of the base body 221, extending outward beyond the peripheral side of the base body 221, thereby providing a larger contact area between the base body 221 and the foam material of the foam layer, making the base body 221 more stable within the foam layer. The wing plate 2212 protruding from the outer periphery of the base body 221 also restricts the rotation of the base body 221 within the foam layer.

[0050] In this embodiment, the inner circumference of the engagement hole 229 is circular, and the engagement hole 229 is provided with an internal thread so that the door handle 300 can be installed on the door shell 210 after the refrigerator is transported to its destination.

[0051] In this embodiment, the nut 223 is integrally injection molded into the engagement hole 229, and an internal thread is formed within the engagement hole 229. The nut 223 is made of metal. The metal material of the nut 223 ensures the strength of the internal thread within the engagement hole 229.

[0052] In some embodiments, no nut 223 is provided in the engagement hole 229, and the internal thread is formed by machining the inner peripheral wall of the engagement hole 229.

[0053] In this embodiment, the rear end of the engagement hole 229 is closed to prevent foaming material from entering the engagement hole 229 from the rear end during foaming. The engagement hole 229 extends through both sides of the base 221, and the baffle 222 closes the rear end of the engagement hole 229.

[0054] In this embodiment, the baffle 222 is provided with a connecting rib, which is detachably connected to the base 221. The front side of the baffle 222 abuts against the nut 223, thereby closing the rear end of the engagement hole 229, and the connecting rib on the baffle 222 is connected to the inner peripheral wall of the engagement hole 229.

[0055] When installing the door handle 300, the bolt can press the baffle 222 and the seat 221 apart when the fastener and the internal thread in the engagement hole 229 are connected, making the connection of the bolt in the engagement hole 229 more secure. The baffle 222 does not affect the installation of the door handle 300.

[0056] In this embodiment, the base 221, the baffle 222, and the nut 223 are integrally injection molded. After injection molding, the baffle 222 has a gap between its outer periphery and the outer periphery of the retaining hole, and they are connected by connecting ribs.

[0057] Both the seat 221 and the baffle 222 are made of plastic. Compared with the handle seat 220 of the prior art, which is made of metal, the plastic material of the seat 221 and the baffle 222 in this embodiment saves costs.

[0058] In some embodiments, the baffle 222 is attached to the rear side of the seat 221 and closes the engagement hole 229. The baffle 222 is fixed to the sealing seat 221 by means of connecting ribs or adhesive, so as to close the engagement hole 229 and be able to separate from the seat 221 under a certain force.

[0059] In some embodiments, the handle base 220 includes a base body 221 and a nut 223. A locking hole 229 is formed on the front side of the base body 221 and does not penetrate the rear side of the base body 221. The nut 223 is disposed in the locking hole 229.

[0060] In some other embodiments, the handle seat 220 includes only the seat body 221, excluding the nut 223 and the baffle 222. The engaging hole 229 is opened on the front side of the seat body 221 and does not penetrate the rear side of the seat body 221. An internal thread is formed on the inner circumference of the engaging hole 229.

[0061] In other embodiments, the engaging hole 229 extends through both ends of the base 221. The rear end of the engaging hole 229 is not closed. After the handle cover 230 engages in the engaging hole 229, the handle cover 230 can prevent some foam material from entering the engaging hole 229. When installing the door handle, the external thread on the fastener and the internal thread on the engaging hole 229 cooperate. The external thread on the fastener can effectively squeeze out the foam material on the internal thread of the engaging hole 229, similar to self-tapping, which can also realize the installation and fixation of the door handle and the handle base 220.

[0062] In this embodiment, a locking protrusion 2211 is provided on the inner sidewall of the locking hole 229 to limit the handle cover 230 within the locking hole 229. The inner circumference of the locking protrusion 2211 is an arc surface in the axial direction of the locking hole 229.

[0063] In this embodiment, the latching protrusion 2211 is arranged circumferentially around the axis of the engaging hole 229. In some embodiments, the latching protrusion 2211 is spaced at multiple intervals around the axis of the engaging hole 229.

[0064] In this embodiment, the locking protrusion 2211 is located outside the internal thread inside the engagement hole 229, and the inner diameter of the locking protrusion 2211 is larger than the inner diameter of the internal thread.

[0065] In some other embodiments, the engaging hole 229 does not have a protrusion 2211, but a groove is provided in the engaging hole 229. The groove is used to engage and limit the handle cover 230.

[0066] Figure 7 This is a schematic diagram of the handle cover of a refrigerator embodiment of the present invention.

[0067] See Figure 4 and Figure 7 The handle cover 230 can be inserted into the handle base 220 to fix the handle base 220 to the inner side of the door shell 210 before foaming, and to block the perforation 211 on the door shell 210 after foaming. The handle cover 230 includes a cover portion 231 and a locking portion 232 protruding from the cover portion 231; the locking portion 232 is sequentially inserted through the perforation 211 and the locking hole 229, and is detachably locked in the locking hole 229; the cover portion 231 abuts against the outer side of the door shell 210.

[0068] In this embodiment, the engaging portion 232 is arranged along the axial direction of the engaging hole 229 on the handle seat 220. A cavity 2321 is formed inside the engaging portion 232, so that the engaging portion 232 is elastic and can extend and retract radially.

[0069] After the engaging part 232 extends into the engaging hole 229, the engaging part 232 contracts and elastically presses against the inner peripheral wall of the engaging hole 229, and can be pulled out from the engaging hole 229.

[0070] In this embodiment, the engaging portion 232 includes two engaging arms 2322 connected at one end to the cover portion 231 and a connecting arm 2323 connecting the other end of the two engaging arms 2322; the two engaging arms 2322 are spaced apart, and a cavity 2321 is formed between the two engaging arms 2322; the engaging arms 2322 engage in the engaging hole 229.

[0071] In some embodiments, a reinforcing arm is provided in the cavity 2321, the reinforcing arm 2322 is connected between the cover portion 231 and the connecting arm 2323, and is spaced apart from the two engaging arms 2322 to enhance the structural strength of the engaging arm 2322.

[0072] In this embodiment, a limiting protrusion 2324 protrudes from the outer periphery of the engaging portion 232, and the limiting protrusion 2324 elastically abuts against the inner peripheral wall of the engaging hole 229. The outer periphery of the limiting protrusion 2324 is arc-shaped to facilitate its fitting with the engaging hole 229.

[0073] In this embodiment, the limiting protrusion 2324 is disposed on the outer periphery of the engaging arm 2322, and the transition surface between the front end and the rear end of the limiting protrusion 2324 and the engaging arm is a sloped surface or a circular arc surface. The transition surface of the limiting protrusion 2324 and the circular arc surface of the engaging protrusion 2211 cooperate to facilitate the insertion and removal of the limiting protrusion 2324 in the engaging hole 229.

[0074] When the limiting protrusion 2324 engages within the engaging hole 229, the limiting protrusion 2324 is located behind the engaging protrusion 2211 and elastically abuts against the engaging protrusion 2211, causing the handle seat 220 to press firmly against the door shell 210. The cover portion 231 of the handle cover 230 fits against the outer side of the door shell 210, and the limiting protrusion 2324 on the handle cover 230 provides an outward force to the handle seat 220, so that the handle seat 220 is pressed firmly against the door shell 210. This ensures the stability of the handle seat 220's position and effectively prevents foam material from entering the engaging hole 229 from the front side of the handle seat 220.

[0075] In this embodiment, the locking protrusion 2211 abuts against the transition surface at the front end of the limiting protrusion 2324. The cooperation between the locking protrusion 2211 and the limiting protrusion 2324 makes the limiting protrusion 2324 exert a greater force on the handle seat 220, and makes the engagement of the handle seat 220 more stable.

[0076] In some embodiments, when a groove is provided in the engaging hole 229, the limiting protrusion 2324 engages in the groove.

[0077] The outer periphery of the front end of the engaging part 232 is interference-fitted with the through hole 211 to prevent the engaging part 232 from moving radially relative to the through hole 211, thereby effectively ensuring the stability of the position of the handle seat 220 engaged with the engaging part 232.

[0078] In this embodiment, the outer peripheral surface of the engaging part 232 is an arc surface, and the diameter of the front end of the engaging part 232 is larger than the diameter of the through hole 211. When the engaging part 232 engages in the through hole 211, the engaging part 232 is elastic and thus elastically presses against the through hole 211.

[0079] In this embodiment, the outer peripheral surface of the engaging portion 232 is an arc surface, allowing the handle base 220 to rotate relative to the engaging portion 232. After the door body 200 is foamed, the position of the handle base 220 is limited, preventing it from rotating. Therefore, a single handle base 220 only needs to be limited by one handle cover 230. When fixing the door handle, it is only necessary to pre-set one handle base 220 at the corresponding position on the door shell 210 at each end of the door handle. When installing the door handle, only two fasteners need to be installed, improving assembly efficiency.

[0080] In some embodiments, the engaging hole 229 is provided with both a protrusion 2211 and a groove. The outer side of the limiting protrusion 2324 abuts against the protrusion 2211 while the limiting protrusion 2324 extends into the groove, so that the limiting protrusion 2324 is limited in the circumferential direction. The groove restricts the rotation of the limiting protrusion 2324 relative to the handle seat 220.

[0081] In this embodiment, a step is provided on the outer periphery of the cover portion 231 of the handle cover 230, and the step is spaced from the outer side of the door shell 210 so as to facilitate the removal of the handle cover 230 from the door shell 210.

[0082] The cover 231 has a flat structure, so that the handle cover 230 will not protrude from the refrigerator and will not increase the volume of the refrigerator's packaging box during transportation.

[0083] Referring to the above technology, before the door body 200 is foamed, the engaging portion 232 of the handle cover 230 passes sequentially through the through hole 211 of the door shell 210 and the engaging hole 229 of the handle seat 220, limiting and pressing the handle seat 220 against the inner side of the door shell 210. Foaming material is injected into the inner side of the door shell 210 to form a foam layer, which simultaneously covers the handle seat 220, allowing the handle seat 220 to be positioned within the foam layer. During subsequent assembly, the handle cover 230 remains installed on the door shell 210. After the refrigerator is sold, after-sales personnel remove the handle cover 230 and use bolts or screws to engage with the internal threads in the engaging hole 229 of the handle seat 220 to install the door handle onto the door shell 210.

[0084] In this invention, the handle base 220 is provided with a locking hole 229. Before the door body 200 is foamed, the locking part 232 of the handle cover 230 passes through the through hole 211 of the door shell 210 and engages with the locking hole 229. The cover part 231 of the handle cover 230 abuts against the outer side of the door shell 210, thereby limiting the handle base 220 on the door shell 210, thus limiting and fixing the handle base 220, facilitating the limiting of the handle base 220 before the door body 200 is foamed, and sealing the through hole 211 on the door shell 210. After foaming is completed, the handle cover 230 is installed and transported together with the door shell 210. The handle cover 230 is detachably engaged in the engagement hole 229. During after-sales installation, the handle cover 230 is pulled out of the engagement hole 229, and the bolts connect with the internal threads in the engagement hole 229 to fix the door handle to the door shell 210. The detachable engagement of the handle cover 230 and the handle base 220 allows for the positioning and fixing of the handle cover 230 to the handle base 220 before foaming, as well as the sealing of the perforation 211. The positioning of the handle cover 230 and the sealing of the door shell 210 do not require separate bolt installation or removal, simplifying the production process and improving production efficiency.

[0085] Although the invention has been described with reference to several typical embodiments, it should be understood that the terminology used is illustrative and exemplary, and not restrictive. Since the invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
