Description
Technical Field
[0001] This application relates to the field of refrigerator technology, and more particularly to a scissor-type concealed door handle device and a refrigerator. Background Technology
[0002] A refrigerator is a refrigeration device that maintains a constant low temperature, and it's also a product that keeps food or other items at a constant low temperature. To facilitate opening and closing the refrigerator door, a handle is usually placed somewhere on the door. Among these, concealed door handles are particularly valued by users because they don't take up external space, are less prone to dust and other impurities, and are less likely to be scratched or deformed during refrigerator transportation.
[0003] The hidden door handles in related technologies use a rotating handle cover to open or close the hidden door handle. This method not only requires manual closing, but also easily results in situations where multiple rotations are needed to fully close the hidden door handle due to inertia, making the refrigerator's hidden door handle inconvenient to use. Summary of the Invention
[0004] This application provides a scissor-type concealed door handle device and a refrigerator to solve the problem of inconvenience in using concealed door handles in refrigerators.

[0006] The handle body is located at the bottom of one side of the refrigerator door. The handle body includes a handle rotation shaft, a scissor bracket, a spring, and a handle latch. The handle cover includes a handle cover rotation shaft and a limiting groove. Both ends of the scissor bracket have through holes. One end of the scissor bracket is rotatably connected to the handle rotation shaft through the through hole. The other end of the scissor bracket is rotatably connected to the handle cover rotation shaft through the through hole. One end of the spring is fixedly connected to the refrigerator door. The other end of the spring is connected to the limiting groove. When the spring is in an uncompressed state, the outer surface of the handle cover and the outer surface of the door glass are on the same plane. The handle latch is located at the top of the handle body.
[0007] By pressing the handle cover, the scissor bracket can be rotated around the handle rotation axis and the handle cover rotation axis, moving perpendicular to the refrigerator door towards the refrigerator body, exposing the handle position for opening the door; after the external force is removed, the spring rebounds, causing the scissor bracket to rotate in the opposite direction around the handle rotation axis and the handle cover rotation axis, moving perpendicular to the refrigerator door away from the refrigerator body, resetting the handle cover, thus solving the problem of inconvenience in using the refrigerator's hidden door handle.
[0008] Optionally, the spring is located in the middle of the handle body, and there are three springs and three limiting grooves.
[0009] The three springs can reduce vibration, suppress the tilting of the handle cover, and improve overall rigidity.
[0010] Optionally, the handle body further includes a limiting claw, which is located on the side of the handle body near the edge of the refrigerator door; the handle cover also includes a second limiting block; when the spring is in an uncompressed state, the limiting claw engages with the second limiting block.
[0011] The limiting claw and the second limiting block can constrain one side of the handle cover, thereby restoring the outer surface of the handle cover to a position flush with the outer surface of the door glass.
[0012] Optionally, the handle cover is further provided with a first limiting block, which is located on the side of the handle cover away from the second limiting block; when the spring is in an uncompressed state, the first limiting block engages with the door glass of the refrigerator door.
[0013] The first limiting block can constrain the other side of the handle cover, thereby restoring the outer surface of the handle cover to a position flush with the outer surface of the door glass.
[0014] Optionally, the number of scissor lift brackets is two, and each scissor lift bracket includes a first bracket and a second bracket. The first bracket and the second bracket are both strip-shaped structures and are hinged to each other with the center of the first bracket and the second bracket as the axis.
[0015] The scissor bracket 2243 can have good foldability and spatial flexibility by means of the first bracket and the second bracket that are hinged to each other.
[0016] Optionally, the number of handle rotation shafts is four; two of the handle rotation shafts are located at the top of the handle body, and the other two are located at the bottom of the handle body.
[0017] The four handle rotation axes not only provide a more stable connection to one end of the two sets of scissor lift brackets, but also reduce the occurrence of handle body breakage due to localized stress.
[0018] Optionally, the number of the handle cover rotation shafts is four; two of the handle cover rotation shafts are located at the top of the handle cover, and the other two of the handle cover rotation shafts are located at the bottom of the handle cover.
[0019] The four rotating shafts of the handle cover not only provide a more stable connection to the other end of the two sets of scissor brackets, but also reduce the occurrence of handle cover breakage due to localized stress.
[0020] The second aspect of this application provides a refrigerator, including a refrigerator body, a refrigerator door, and the scissor-type concealed door handle device described in the first aspect.
[0021] The refrigerator body and the refrigerator door are hinged together by hinges and support rods; the refrigerator door includes a door glass, a door liner, and a trim strip; the door liner is fixedly connected to the door glass and the scissor-type concealed door handle device respectively; the door glass can be engaged with the scissor-type concealed door handle device; the trim strip is set on the edge of the door glass and the scissor-type concealed door handle device.
[0022] Since the refrigerator has all the beneficial effects of the scissor-type concealed door handle device described in the first aspect above, it will not be repeated here.
[0023] As can be seen from the above technical solutions, this application provides a scissor-type concealed door handle device and a refrigerator. The scissor-type concealed door handle device includes: a handle body and a handle cover. The handle body is located at the bottom of one side of the refrigerator door. The handle body includes a handle rotation shaft, a scissor bracket, a spring, and a handle latch. The handle cover includes a handle cover rotation shaft and a limiting groove. Both ends of the scissor bracket are provided with through holes. One end of the scissor bracket is rotatably connected to the handle rotation shaft through the through hole. The other end of the scissor bracket is rotatably connected to the handle cover rotation shaft through the through hole. One end of the spring is fixedly connected to the refrigerator door. The other end of the spring is connected to the limiting groove. When the spring is in an uncompressed state, the outer surface of the handle cover and the outer surface of the door glass are on the same plane.

Detailed Implementation
[0031] The embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described below do not represent all embodiments consistent with this application. They are merely examples of systems and methods consistent with some aspects of this application as detailed in the claims.
[0032] A refrigerator is a refrigeration device that maintains a constant low temperature, and it's also a product that keeps food or other items at a constant low temperature. To facilitate opening and closing the refrigerator door, a handle is usually placed somewhere on the door. Among these, concealed door handles are particularly valued by users because they don't take up external space, are less prone to dust and other impurities, and are less likely to be scratched or deformed during refrigerator transportation.
[0033] In the relevant embodiments, the hidden door handle is opened or closed by rotating the handle cover. This method not only requires manual closing, but also easily results in the need to rotate multiple times to fully close the hidden door handle due to inertia, making the refrigerator's hidden door handle inconvenient to use.
[0034] To address the inconvenience of using concealed door handles on refrigerators, see [link / reference]. Figures 1-3 ,in, Figure 1 A schematic diagram of the structure of a scissor-type concealed door handle device after installation; Figure 2A schematic diagram of the main handle structure of a scissor-type concealed door handle device; Figure 3 This is a schematic diagram of the handle cover structure of a scissor-type concealed door handle device. Some embodiments of this application provide a scissor-type concealed door handle device, including: a handle body 224 and a handle cover 225. The handle body 224 is located at the bottom of one side of the refrigerator door 2. The handle body 224 includes a handle rotation shaft 2242, a scissor bracket 2243, a spring 2244, and a handle latch. The handle cover 225 includes a handle cover rotation shaft 2252 and a limiting groove 2253. Both ends of the scissor bracket 2243 are provided with through holes. One end of the scissor bracket 2243 is rotatably connected to the handle rotation shaft 2242 through the through hole. The other end of the scissor bracket 2243 is rotatably connected to the handle cover rotation shaft 2252 through the through hole. One end of the spring 2244 is fixedly connected to the refrigerator door 2. The other end of the spring 2244 is connected to the limiting groove 2253. When the spring 2244 is in an uncompressed state, the outer surface of the handle cover 225 and the outer surface of the door glass 221 are on the same plane. The handle latch is located at the top of the handle body 224.
[0035] It should be understood that the handle cover 225 consists of three surfaces: the front surface, the side surface, and the bottom surface. The side of the front surface of the handle cover closest to the refrigerator body 1 is the inner surface, and the side furthest from the refrigerator body 1 is the outer surface. The limiting groove 2253 is provided on the inner surface. The outer surface of the handle cover 225 and the outer surface of the door glass 221 are made of the same material and color. The outer surfaces of the side surface and the bottom surface of the handle cover are both provided with decorative strips 223, which can better conceal the handle cover 225. By pressing the handle cover 225, the scissor bracket 2243 can be rotated around the handle rotation axis 2242 and the handle cover rotation axis 2252, so that it moves perpendicular to the refrigerator door 2 towards the refrigerator body 1, exposing the handle position for opening the door; after the external force is removed, the spring 2244 rebounds, causing the scissor bracket 2243 to rotate in the opposite direction around the handle rotation axis 2242 and the handle cover rotation axis 2252, so that it moves perpendicular to the refrigerator door 2 away from the refrigerator body 1, resetting the handle cover 225. This not only reduces the harm to the human body in case of accidental contact, but also solves the problem of the inconvenience of using the refrigerator's hidden door handle.
[0036] Specifically, without any external force applied, the handle cover 225 is flush with the door glass 221, concealing the handle position and achieving a smooth overall appearance for the refrigerator door 2. When the refrigerator door 2 needs to be opened, under external force, the scissor bracket 2243 rotates around the handle rotation axis 2242 and the handle cover rotation axis 2252, respectively. The handle cover 225 moves perpendicular to the refrigerator door 2 towards the refrigerator body 1, exposing the handle position and enabling the door to open. After the external force is removed, the spring 2244 is in a compressed state and applies an outward force to the handle cover 225. The scissor bracket 2243 rotates in opposite directions around the handle rotation axis 2242 and the handle cover rotation axis 2252 respectively. The handle cover 225 moves perpendicular to the refrigerator door 2 away from the refrigerator body 1, making the outer surface of the handle cover 225 flush with the outer surface of the door glass 221, improving the overall appearance of the refrigerator door and the concealment effect of the door handle structure.
[0037] In some embodiments, the spring 2244 is located at the middle position of the handle body 224, and there are three springs 2244 and three limiting grooves 2253.
[0038] It should be understood that the three springs 2244 are the same size, arranged in parallel with equal spacing. The three springs 2244 can reduce vibration, suppress the tilt of the handle cover 225, and improve the overall rigidity.
[0039] In some embodiments, the handle body 224 further includes a limiting claw 2241, which is located on the side of the handle body 224 near the edge of the refrigerator door 2; the handle cover 225 further includes a second limiting block 2254; when the spring 2244 is in an uncompressed state, the limiting claw 2241 engages with the second limiting block 2254.
[0040] It should be understood that the vertical distance between the second limiting block 2254 and the outer surface of the handle cover 225 is equal to the vertical distance between the limiting claw 2241 and the outer surface of the door glass 221. After the external force is removed, the spring 2244 applies an outward force to the handle cover 225, causing the handle cover 225 to move perpendicularly to the refrigerator door 2 away from the refrigerator body 1. The limiting claw 2241 and the second limiting block 2254 can constrain one side of the handle cover 225, thereby restoring the outer surface of the handle cover 225 to a position flush with the outer surface of the door glass 221.
[0041] In some embodiments, the handle cover 225 is further provided with a first limiting block 2251, which is located on the side of the handle cover 225 away from the second limiting block 2254; when the spring 2244 is in an uncompressed state, the first limiting block 2251 engages with the door glass 221 of the refrigerator door body 2.
[0042] It should be understood that the first limiting block 2251 may be a cuboid structure, and the distance between the limiting block 2251 and the outer surface of the handle cover 225 is equal to the thickness of the door glass 221. After the external force is removed, the spring 2244 applies an outward force to the handle cover 225, causing the handle cover 225 to move perpendicularly to the refrigerator door 2 away from the refrigerator body 1. The first limiting block 2251 can constrain the other side of the handle cover 225, thereby restoring the outer surface of the handle cover 225 to a position flush with the outer surface of the door glass 221.
[0043] In some embodiments, there are two scissor lift brackets 2243, each of which includes a first bracket and a second bracket. Both the first bracket and the second bracket are strip-shaped structures and are hinged to each other with the center of the first bracket and the second bracket as the axis.
[0044] The scissor lift bracket 2243 can have good foldability and spatial flexibility due to the mutual hinge of the first and second supports. In some other embodiments, the scissor lift bracket 2243 may also include multiple mutually hinged supports.
[0045] In some embodiments, the number of handle rotation shafts 2242 is four; two handle rotation shafts 2242 are located at the top of the handle body 224, and the other two handle rotation shafts 2242 are located at the bottom of the handle body 224.
[0046] The four handle rotation shafts 2242 can not only be connected more stably to one end of the two sets of scissor brackets 2243, but also reduce the occurrence of the handle body 224 breaking due to local stress.
[0047] In some embodiments, the number of the handle cover rotation shafts 2252 is four; two of the handle cover rotation shafts 2252 are located at the top of the handle cover 225, and the other two of the handle cover rotation shafts 2252 are located at the bottom of the handle cover 225.
[0048] The four handle cover rotation shafts 2252 not only provide a more stable connection to the other end of the two sets of scissor brackets 2243, but also reduce the occurrence of local stress causing the handle cover 225 to break.
[0049] This application also provides a refrigerator in some embodiments, including a refrigerator body 1, a refrigerator door 2, and the scissor-type concealed door handle device described in the above embodiments.
[0050] The refrigerator body 1 and the refrigerator door 2 are hinged together by hinges and support rods; the refrigerator door 2 includes a door glass 221, a door insert 222, and a trim strip 223; the door insert 222 is fixedly connected to the door glass 221 and the scissor-type hidden door handle device respectively; the door glass 221 can be engaged with the scissor-type hidden door handle device; the trim strip 223 is provided on the edges of the door glass 221 and the scissor-type hidden door handle device.
[0051] Since the refrigerator has all the beneficial effects of the scissor-type concealed door handle device described in the above embodiments, it will not be repeated here.
[0052] It should be understood that, see Figure 4 , Figure 4 This is a schematic diagram of a refrigerator structure. The refrigerator body 1 can be a French four-door refrigerator body, and the refrigerator door 2 may include a freezer door and a refrigerator door. See again. Figure 2 The decorative strip 223 can be installed on the side and bottom of the refrigerator door 2, and the scissor-type hidden door handle device can be better hidden through the decorative strip 223.
[0053] As can be seen from the above technical solutions, the embodiments of this application provide a scissor-type concealed door handle device and a refrigerator. The scissor-type concealed door handle device includes: a handle body 224 and a handle cover 225. The handle body 224 is located at the bottom of one side of the refrigerator door 2. The handle body 224 includes a handle rotation shaft 2242, a scissor bracket 2243, a spring 2244, and a handle latch. The handle cover 225 includes a handle cover rotation shaft 2252 and a limiting groove 2253. Both ends of the scissor bracket 2243 are provided with through holes. One end of the scissor bracket 2243 is rotatably connected to the handle rotation shaft 2242 through the through hole. The other end of the scissor bracket 2243 is rotatably connected to the handle cover rotation shaft 2252 through the through hole. One end of the spring 2244 is fixedly connected to the refrigerator door 2. The other end of the spring 2244 is connected to the limiting groove 2253. When the spring 2244 is in an uncompressed state, the outer surface of the handle cover 225 and the outer surface of the door glass 221 are on the same plane. The handle latch is located at the top of the handle body 224. By pressing the handle cover 225, the scissor bracket 2243 can be rotated around the handle rotation axis 2242 and the handle cover rotation axis 2252, moving perpendicular to the refrigerator door 2 towards the refrigerator body 1, exposing the handle position for opening the door; after the external force is removed, the spring 2244 compresses and rebounds, causing the scissor bracket 2243 to rotate in the opposite direction around the handle rotation axis 2242 and the handle cover rotation axis 2252, moving perpendicular to the refrigerator door 2 away from the refrigerator body 1, resetting the handle cover 225, thus solving the problem of inconvenience in using the refrigerator's hidden door handle.
