Abstract
Description
Technical Field
[0001] This invention relates to the field of refrigeration equipment, and more particularly to a refrigerator. Background Technology
[0002] With the development of refrigerators towards intelligence and multi-functionality, refrigerator doors are usually equipped with some functional modules, such as ice water modules and touch control modules. These functional modules usually need to be connected to other modules in the refrigerator through pipelines in order to provide power, water and cooling to the various functional modules on the door.
[0003] Existing wiring connecting the door and the housing typically uses hinges on the door for routing. These hinges have through holes running vertically, through which wiring from the housing passes and extends into the door to connect with various functional modules. However, limitations in hinge size and strength restrict the through holes. With numerous wiring options, this congestion increases wear and tear, reducing the wiring's lifespan. Furthermore, these wirings often include both water pipes and electrical wires (both high-voltage and low-voltage). Wear or breakage of these congested pipes or wires can cause leaks or electrical malfunctions, posing safety hazards.
[0004] Chinese invention patent CN110130758B discloses a hinge assembly for a refrigerator, which solves the technical problem of difficulty in simultaneously allowing pipelines to enter the door through a single hinge structure by providing a second hinge structure for additional pipelines to pass through. However, on the one hand, the second hinge structure is a movable junction box structure. During the opening and closing of the door, the movable junction box itself swings too much, causing friction between the pipelines and affecting their service life. At the same time, when both high-voltage and low-voltage wires run inside the movable junction box, the pipelines will be severely worn due to compression and deformation, and noise will be generated.
[0005] In view of this, it is necessary to provide a new refrigerator to solve the above problems. Summary of the Invention
[0006] The purpose of this invention is to provide a refrigerator.
[0007] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: a refrigerator, comprising a cabinet, a door rotatably connected to the front side of the cabinet, and a pipeline extending from the cabinet to the door body, wherein the door body has a receiving groove for receiving the pipeline; the rear wall of the door body has an opening communicating with the receiving groove; the refrigerator further comprises a wire box fixed to the cabinet, wherein the outlet end of the wire box protrudes from the opening into the receiving groove, and at least a portion of the pipeline extends into the door body through the wire box.
[0008] As a further improvement of the present invention, the refrigerator also includes a baffle that is movably disposed in the receiving slot, the baffle being located between the pipeline and the opening, so that the pipeline is always located in the receiving slot.
[0009] As a further improvement of the present invention, the baffle is rotatably connected to the outlet end of the wire box, and the pipeline led out from the outlet end extends into the door body from the front side of the baffle.
[0010] As a further improvement of the present invention, the receiving groove also has a guide groove, and the end of the baffle away from the wire box has a guide post that is slidably connected to the guide groove.
[0011] As a further improvement of the present invention, the end of the guide groove near the rear wall of the door is close to the edge of the opening.
[0012] As a further improvement of the present invention, when the guide post is located at one end of the guide groove near the rear wall of the door, the baffle covers the gap between the wire box and the opening.
[0013] As a further improvement of the present invention, the end of the baffle away from the wire box has an anti-detachment part. When the guide post is located at the end of the guide groove near the rear wall of the door, the anti-detachment part is located on the side of the rear wall near the opening facing the front wall of the door.
[0014] As a further improved technical solution of the present invention, the door body has a pivot end rotatably connected to the box body and a free end opposite to the pivot end. The pipeline led out from the outlet end extends toward the free end, and the baffle extends from the outlet end toward the free end. The guide groove extends obliquely from one end near the front wall of the door body toward the rear wall and toward the pivot end.
[0015] As a further improvement of the present invention, the baffle includes a first plate and end plates extending from the upper and lower ends of the first plate toward the front wall of the door body, respectively, and the end plates are fitted with the receiving groove with a clearance.
[0016] As a further improved technical solution of the present invention, the refrigerator also includes a hinge plate disposed on the cabinet, the hinge plate having a hinge shaft rotatably connected to the door body, the hinge shaft having a wiring hole that runs through it in the vertical direction, and the remaining pipeline extending into the door body through the wiring hole.
[0017] As a further improved technical solution of the present invention, the pipeline includes a refrigeration inlet pipe, a refrigeration return pipe, a water pipe, a high-voltage wire, and a low-voltage wire; the refrigeration inlet pipe, the refrigeration return pipe, and the water pipe extend into the door body through the wiring hole, and the high-voltage wire and the low-voltage wire extend into the door body through the wire box.
[0018] The beneficial effects of the present invention are as follows: In the refrigerator of the present invention, by setting a wire box fixedly connected to the cabinet, the pipeline inside the wire box will not move or will move only slightly during the opening and closing of the door. This reduces the bending of the pipeline inside the wire box, reduces the friction between the pipelines inside the wire box, reduces noise, and increases the service life of the pipeline.

[0026] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. Please refer to the accompanying drawings for further details. Figure 1 - Figure 7 The figures shown represent preferred embodiments of the present invention. However, it should be noted that these embodiments are not intended to limit the invention. Any functional, methodological, or structural equivalent modifications or substitutions made by those skilled in the art based on these embodiments are within the scope of protection of the present invention. The accompanying drawings of the present invention only show a schematic diagram of the refrigerator structure corresponding to one side of the door.
[0027] In this invention, terms describing position and direction are defined with the side of the refrigerator facing the user as the front and the side away from the user as the back when the refrigerator is in normal use. Furthermore, it should be noted that unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, a connection can be a direct connection or an indirect connection through an intermediate medium; it can be a fixed connection, a movable connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0028] Please refer to Figures 1-7 As shown, the present invention provides a refrigerator 100, including a cabinet 1, a door 2 rotatably connected to the front side of the cabinet 1, and a pipeline 3 extending from the cabinet 1 into the door 2. The pipeline 3 is used to provide power and / or water and / or cooling to various functional modules on the door 2.
[0029] Specifically, the door 2 has a pivot end rotatably connected to the housing 1 and a free end opposite to the pivot end.
[0030] The refrigerator 100 also includes a wiring box 4 fixed to the cabinet 1 and protruding toward the door 2, through which at least a portion of the conduits 3 extend into the door 2. The wiring box 4 is fixedly installed, and during the opening and closing of the door 2, the conduits 3 within the wiring box 4 do not move or move only slightly. This reduces bending of the conduits 3 within the wiring box 4, reduces friction between the conduits 3 within the wiring box 4, lowers noise, increases the service life of the conduits 3, and enhances safety performance.
[0031] Furthermore, the door body 2 has a receiving groove 21 for accommodating the conduit 3 passing through the wiring box 4. The rear wall 22 of the door body 2 has an opening 221 communicating with the receiving groove 21. The outlet end of the wiring box 4 protrudes into the receiving groove 21 from the opening 221. During the opening and closing of the door body 2, the outlet end is always located within the receiving groove 21, which can prevent the conduit 3 from being exposed to the outside of the door body 2, enhance the stability of the fit between the wiring box 4 and the receiving groove 21, and enhance the appearance of the door body 2. At the same time, during the opening and closing of the door body 2, the conduit 3 extending from the outlet end into the receiving groove 21 has a large degree of freedom of movement, which can avoid friction and bending, reduce noise, increase the service life of the conduit 3, and enhance safety performance.
[0032] It is known that the width of the opening 221 is greater than the width of the wiring box 4, so that there will be no interference between the wiring box 4 and the door 2 during the opening and closing process. At the same time, the height of the opening 221 is matched with the clearance between the wiring box 4 and the door 2 to reduce friction between the wiring box 4 and the door 2 and reduce noise.
[0033] Specifically, the door body 2 includes an upper trim strip 23, and the receiving groove 21 is formed by the downward recess of the upper trim strip 23, and the receiving groove 21 opens rearward. The door body 2 also includes a cover plate 24 for covering the receiving groove 21 to prevent the pipeline 3 from being exposed upward on the outside of the door body 2. At the same time, the cover plate 24 and the rear end of the receiving groove 21 together form the opening 221.
[0034] As can be seen, in this embodiment, the rear wall 22 of the door body 2 includes the rear wall 22 of the upper trim 23, and the rear wall 22 of the door body 2 has the opening 221, that is, the rear wall 22 of the upper trim 23 has the opening 221. Of course, this is not a limitation.
[0035] Furthermore, the refrigerator 100 also includes a baffle 5 movably disposed within the receiving slot 21. During the opening and closing of the door 2, the baffle 5 is positioned between the pipeline 3 and the opening 221 to prevent the pipeline 3 from being exposed outwards through the gap between the wire box 4 and the opening 221, ensuring that the pipeline 3 remains within the receiving slot 21. That is, the baffle 5, the receiving slot 21, and the cover plate 24 together form a limiting space for the pipeline 3, ensuring that the pipeline 3 remains within the receiving slot 21, preventing its exposure, enhancing the appearance of the refrigerator 100, and improving safety performance.
[0036] In one specific embodiment, the baffle 5 is rotatably connected to the outlet end of the wire box 4. The conduit 3 leading from the outlet end extends into the door body 2 from the front side of the baffle 5, which can better stop the conduit 3 and simplify the connection structure between the baffle 5 and the receiving groove 21. During the opening and closing of the door body 2, the baffle 5 is always located between the conduit 3 and the opening 221 to prevent the conduit 3 from being exposed outward from the gap between the wire box 4 and the opening 221. Of course, this is not a limitation; in other embodiments, the baffle 5 can also be configured to be movably connected to the upper trim strip 23.
[0037] Furthermore, the receiving groove 21 also has a guide groove 211, and the end of the baffle 5 away from the wire box 4 has a guide post 51 slidably connected to the guide groove 211. That is, one end of the baffle 5 is rotatably connected to the outlet end, and the other end is slidably connected to the receiving groove 21. During the opening and closing of the door 2, the guide groove 211 and the guide post 51 cooperate to guide the movement of the baffle 5, reduce the shaking of the baffle 5 in the receiving groove 21, and enhance the blocking effect of the baffle 5 on the pipeline 3.
[0038] Furthermore, the end of the guide groove 211 near the rear wall 22 of the door body 2 is close to the edge of the opening 221. When the door body 2 is opened and closed until the guide post 51 is located at the end of the guide groove 211 near the rear wall 22 of the door body 2, the baffle 5 covers the gap between the wire box 4 and the opening 221 to prevent the pipeline 3 from being exposed.
[0039] In one specific embodiment, the end of the guide groove 211 near the rear wall 22 of the door body 2 extends from the inner periphery of the opening 221 to the edge of the opening 221, which can reduce the influence of the cooperation between the guide groove 211 and the guide post 51 on the opening of the door body 2 and increase the opening of the door body 2.
[0040] Furthermore, combined Figure 4 , Figure 7 As shown, the baffle 5 includes a baffle body 52 rotatably connected to the outlet end and an anti-detachment part 53 located at the end of the baffle body 52 away from the wire box 4. When the guide post 51 is located at the end of the guide groove 211 near the rear wall 22 of the door body 2, the baffle body 52 covers the gap between the wire box 4 and the opening 221. At the same time, the anti-detachment part 53 is located on the side of the rear wall 22 near the opening 221 facing the front wall of the door body 2, that is, the anti-detachment part 53 is located on the front side of the rear wall 22 at the opening 221, so as to prevent the end of the baffle 5 away from the wire box 4 from detaching from the opening 221 or becoming flush with the opening 221, which would cause the end of the baffle 5 away from the wire box 4 to interfere with the periphery of the opening 221 during the opening and closing of the door body 2, affecting the opening and closing of the door body 2, and at the same time preventing damage to the baffle 5.
[0041] In this embodiment, the pipeline 3 leading out from the outlet end extends toward the free end, and the baffle 5 extends from the outlet end toward the free end; the guide groove 211 extends obliquely from one end near the front wall of the door body 2 toward the rear wall 22 and toward the pivot end. This is more conducive to the arrangement of the pipeline 3 and reduces interference between the pipeline 3 passing through the wire box 4 and other pipelines 3. Of course, this is not a limitation; the extension direction of the baffle 5 only needs to be set to be the same as the extension direction of the pipeline 3 in the receiving groove 21, and can always be located between the pipeline 3 and the opening 221.
[0042] Furthermore, combined Figure 5 As shown, the baffle 5 includes a first plate 521 and end plates 522 extending from the upper and lower ends of the first plate 521 toward the front wall of the door body 2, respectively. The end plates 522 are clearance-fitted with the receiving groove 21. That is, the lower end plate 522 is clearance-fitted with the bottom of the receiving groove 21, and the upper end plate 522 is clearance-fitted with the cover plate 24. On the one hand, this can prevent the pipeline 3 from coming out of the gap between the upper or lower side of the baffle 5 and the receiving groove 21; on the other hand, it can reduce the friction between the baffle 5 and the receiving groove 21 during the opening and closing of the door body 2, thereby reducing noise.
[0043] Specifically, the first plate 521 and the end plate 522 mentioned above together form the baffle body 52. The specific structure of the anti-detachment part 53 is not limited here.
[0044] Furthermore, the refrigerator 100 also includes a hinge box 6 fixed to the cabinet 1, and the wire box 4 is fixed to the hinge box 6. The fixed connection between the wire box 4 and the cabinet 1 is achieved by the hinge box 6 fixed to the cabinet 1, which can reduce the connection parts on the cabinet 1 and simplify the assembly of the refrigerator 100.
[0045] Furthermore, after the wire box 4 is fixed to the hinge box 6, the hinge box 6 completely covers the wire box 4 to completely conceal the wire box 4 and enhance the appearance of the refrigerator 100.
[0046] Specifically, the hinge box 6 includes a middle hinge box 61 and an end hinge box 62 located at the end of the middle hinge box 61, and the wire box 4 is fixed to the middle hinge box 61.
[0047] Furthermore, the hinge box 61 has a receiving portion 611 that protrudes toward the door body 2 and is used to receive the wire box 4, the shape of the receiving portion 611 being adapted to the shape of the wire box 4.
[0048] Specifically, the receiving portion 611 includes an upper wall 6111 that covers the upper surface of the wire box 4, a lower wall 6112 located on the lower surface of the wire box 4, and a connecting wall 6113 on one side connecting the upper wall 6111 and the lower wall 6112. After the wire box 4 is fixed to the hinge box 6, the part of the wire box 4 that protrudes toward the door 2 is received in the receiving portion 611, and the wire box 4 is supported on the lower wall 6112.
[0049] Furthermore, the wire box 4 and the receiving part 611 together form a wiring groove for the conduit 3 to pass through. Specifically, the side of the wire box 4 corresponding to the connecting wall 6113 is open, so the conduit 3 can be first inserted into the wire box 4 through the side of the wire box 4 facing the connecting wall 6113. Then, the wire box 4 is assembled with the central hinge box 61 to form the wiring groove that guides and limits the conduit 3, facilitating the arrangement of the conduit 3.
[0050] Furthermore, the refrigerator 100 also includes a hinge plate 7 fixed to the cabinet 1, the hinge plate 7 having a hinge shaft 71 rotatably connected to the door 2. That is, the door 2 is rotatably connected to the hinge shaft 71. The end hinge box 62 is used to cover the hinge plate 7.
[0051] The hinge shaft 71 has a through-hole 711 extending vertically, through which the remaining conduit 3 extends into the door body 2. That is, in this invention, part of the conduit 3 extends into the door body 2 via the hinge shaft 71, and another part extends into the door body 2 via the wire box 4. This reduces the limitations on wiring in the hinge shaft 71 of the prior art, allows for flexible adjustment of the extension trajectory of each conduit 3, and avoids wire jamming.
[0052] Specifically, in combination Figure 3 As shown, the pipeline 3 includes a refrigeration inlet pipe 31, a refrigeration return pipe 32, a water pipe 33, a high-voltage wire 34, and a low-voltage wire 35. The refrigeration inlet pipe 31, the refrigeration return pipe 32, and the water pipe 33 extend into the door body 2 through the wiring hole 711, while the high-voltage wire 34 and the low-voltage wire 35 extend into the door body 2 through the wiring box 4. On the one hand, separating the water pipe 33 from the electrical wires avoids the impact of water leakage from the water pipe 33 on the electrical wires. On the other hand, routing the high-voltage wire 34 and the low-voltage wire 35 through the wiring box 4 ensures that the high-voltage wire 34 and the low-voltage wire 35 do not move relative to each other or move only slightly during the opening and closing of the door body 2. This reduces bending of the high-voltage wire 34 and the low-voltage wire 35, reduces friction between them within the wiring box 4, lowers noise, increases the service life of the high-voltage wire 34 and the low-voltage wire 35, and enhances safety performance.
[0053] In summary, the refrigerator 100 of the present invention, by setting a wire box 4 fixedly connected to the cabinet 1, ensures that the pipes 3 inside the wire box 4 do not move or move only slightly during the opening and closing of the door 2. This reduces the bending of the pipes 3 inside the wire box 4, reduces friction between the pipes 3 inside the wire box 4, reduces noise, and increases the service life of the pipes 3.
[0054] Meanwhile, a baffle 5 is installed in the receiving groove 21 on the door 2 to receive the pipeline 3, which can prevent the pipeline 3 from being exposed and keep the pipeline 3 always within the receiving groove 21, thereby enhancing the appearance of the refrigerator 100 and improving its safety performance.
[0055] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
[0056] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. All equivalent embodiments or modifications made without departing from the spirit of the present invention should be included within the scope of protection of the present invention.
