Technical Field

[0001] This utility model belongs to the field of refrigerator technology and relates to the door opening and closing structure of a fully integrated refrigerator. Background Technology

[0002] As living standards improve, people have higher and higher aesthetic requirements for decoration and home appliances. Therefore, built-in refrigerators are being accepted and adopted by more and more people because they can be embedded in the cabinet and are more consistent with the cabinet in appearance.

[0003] Built-in refrigerators often use concealed door handles for aesthetic purposes. Concealed door handles are favored by users because they don't take up external space, are less prone to dust and debris accumulation, and are less likely to be scratched or accidentally bumped during transport. However, these concealed door handles are electrically controlled, and their complex internal components not only take up internal space and are inconvenient to install, but they are also prone to malfunctions, leading to problems such as inability to open the door or electrical leakage, making them very inconvenient to use.

[0004] The following technical problems were found in the existing technology: the electrically controlled hidden door handle device has too many internal components, which not only takes up internal space and is inconvenient to install, but is also prone to failure, resulting in failure to open or leakage of electricity, making it very inconvenient to use. Utility Model Content

[0005] The technical problem this invention aims to solve is that the electric hidden door handle device is inconvenient for opening and closing the cabinet door.

[0006] The door opening and closing structure of the fully integrated refrigerator described in this utility model includes a refrigerator body, a slide rail installed inside the side wall of the refrigerator body, a slide plate slidably connected inside the slide rail, a refrigerator door fixedly connected to the end of the slide plate away from the refrigerator body, a decorative panel fixedly connected to the top of the refrigerator door, a mounting box fixedly connected to the side of the decorative panel near the refrigerator body, a rectangular hole opened inside the decorative panel and corresponding to the mounting box, a handle slidably connected inside the mounting box, and a locking mechanism provided inside the mounting box.

[0007] The refrigerator body has hanging ears fixedly connected to the inner walls on both sides, and a hanging plate is slidably connected above the hanging ears.

[0008] A magnetic sealing strip is fixedly connected to the side of the refrigerator door near the refrigerator body. The magnetic sealing strip has a silicone sleeve on the outside and a magnetic strip on the inside.

[0009] Both sides of the sliding plate are rotatably connected to pulleys, which are rolledly connected to the slide rail. A sound-silencing pad is fixedly connected inside the slide rail at a position corresponding to the pulley. The width of the sound-silencing pad is adapted to the width of the pulley, and the length of the sound-silencing pad is adapted to the length of the slide rail.

[0010] Both sides of the handle are fixedly connected to sliders, and the mounting box has sliding grooves on both sides corresponding to the sliders, and the sliders are slidably connected to the sliding grooves.

[0011] The locking mechanism includes a positioning block. Positioning blocks are slidably connected to both sides of the handle. The end of the positioning block away from the side wall of the mounting box is arc-shaped. Positioning grooves are provided on both sides of the mounting box and at the corresponding positions of the positioning blocks.

[0012] Both sides of the positioning block are fixedly connected with protrusions, and a convex groove is opened inside the handle at the position corresponding to the protrusion. The protrusion and the convex groove are slidably connected.

[0013] A limiting post is fixedly connected inside the convex groove. A circular hole is opened through the inside of the protrusion and corresponding to the limiting post. The circular hole is slidably connected to the limiting post. A spring is sleeved on the outside of the limiting post.

The magnetic sealing strip 201 has a silicone sleeve on the outside and a magnetic strip on the inside. The silicone sleeve can enhance the sealing effect, and the magnetic strip can make the refrigerator door 2 fit tightly with the refrigerator body 1.

[0026] A decorative panel 5 is fixedly connected to the top of the refrigerator door 2. A mounting box 6 is fixedly connected to the side of the decorative panel 5 near the refrigerator body 1. The mounting box 6 can hide the handle 7, so that the refrigerator door 2 has no protrusion and the overall appearance is neater and more beautiful. A rectangular hole 501 is opened inside the decorative panel 5 and corresponding to the mounting box 6. The handle 7 is slidably connected inside the mounting box 6. A slider 701 is fixedly connected to both sides of the handle 7. A sliding groove 601 is opened on both sides of the mounting box 6 and corresponding to the slider 701. The slider 701 is slidably connected to the sliding groove 601. The handle 7 can slide inside the mounting box 6 through the cooperation of the slider 701 and the sliding groove 601.

[0027] When in use, if you need to open the refrigerator door 2, first unlock the handle 7, then slide the handle 7 out of the mounting box 6 and pull the handle 7 to open the refrigerator door 2. When the refrigerator door 2 moves, it drives the sliding plate 4 and the pulley 401 to move inside the slide rail 3. The sound-dampening pad 301 set inside the slide rail 3 can reduce the noise of the pulley 401 sliding inside the slide rail 3 and improve the user experience.

[0028] The mounting box 6 is equipped with a locking mechanism, which includes positioning blocks 8. Positioning blocks 8 are slidably connected to both sides of the handle 7, and can lock the handle 7. The end of the positioning block 8 away from the side wall of the mounting box 6 is arc-shaped. Positioning grooves 602 are opened on both sides of the mounting box 6 and corresponding to the positioning blocks 8. Protrusions 801 are fixedly connected to both sides of the positioning blocks 8. A convex groove is opened inside the handle 7 and corresponding to the protrusions 801. The protrusions 801 are slidably connected to the convex grooves. A limiting post 9 is fixedly connected inside the convex grooves. A circular hole is opened through the protrusions 801 and corresponding to the limiting post 9. The circular hole is slidably connected to the limiting post 9. The limiting post 9 and the protrusions 801 cooperate to guide the positioning blocks 8. A spring 901 is sleeved on the outside of the limiting post 9. One end of the spring 901 is fixedly connected to the inner wall of the convex groove, and the other end of the spring 901 is fixedly connected to the protrusions 801.

[0029] The locking mechanism also includes a pressing plate 10 and a squeezing plate 11. A squeezing plate 11 is provided inside the mounting box 6 and corresponding to the positioning block 8. The squeezing plate 11 contacts the arc-shaped end of the positioning block 8 and can push the positioning block 8 to move by squeezing the arc-shaped end of the positioning block 8. The pressing plate 10 is fixedly connected to the side of the squeezing plate 11 near the handle 7. The pressing plate 10 can drive the squeezing plate 11 to move. A sliding column 1101 is fixedly connected to the other side of the squeezing plate 11. A guide hole is provided on the inner wall of the mounting box 6 and corresponding to the sliding column 1101. The guide hole is slidably connected to the sliding column 1101. The guide hole and the sliding column 1101 cooperate to guide the squeezing plate 11. A second spring 1102 is sleeved on the outside of the sliding column 1101. One end of the second spring 1102 is fixedly connected to the squeezing plate 11, and the other end is fixedly connected to the inner wall of the mounting box 6.

[0030] When in use, if you need to pull the handle 7 out of the mounting box 6, first push the pressing plate 10 into the mounting box 6. The pressing plate 10 drives the squeezing plate 11 to move, and the second spring 1102 is compressed. The squeezing plate 11 moves away from the positioning block 8. At this time, the first spring 901 returns to its original position, pushing the protrusion 801 to slide along the outside of the limiting post 9. The protrusion 801 drives the positioning block 8 to move, so that the positioning block 8 is disengaged from the positioning groove 602, thus releasing the lock on the handle 7. Then you can pull out the handle 7. After use, you need to push the handle 7 back into the mounting box 6 to hide it. First, push the pressing plate 10 into the mounting box 6. The pressing plate 10 drives the squeezing plate 11 to move, and the second spring 1102 is compressed. Then slide the handle 7 into the mounting box 6, release the pressing plate 10, and the second spring 1102 returns to its original position, driving the squeezing plate 11 to move. The squeezing plate 11 squeezes the arc-shaped end of the positioning block 8 and pushes the positioning block 8 to move, so that the positioning block 8 enters the positioning groove 602, thus locking the handle 7.

[0031] During operation, to open the refrigerator door 2, first push the pressing plate 10 into the mounting box 6. The pressing plate 10 moves the squeezing plate 11, compressing the second spring 1102. The squeezing plate 11 moves away from the positioning block 8, at which point the first spring 901 returns to its original position, pushing the protrusion 801 to slide along the outside of the limiting post 9. The protrusion 801 moves the positioning block 8, causing it to disengage from the positioning groove 602, releasing the lock on the handle 7. Then, the handle 7 can be pulled out to open the refrigerator door 2. When the refrigerator door 2 moves, it causes the sliding plate 4 and the pulley 401 to move inside the slide rail 3. The sound-absorbing pad 301 inside the slide rail 3 reduces the noise of the pulley 401 sliding inside the slide rail 3, improving the user experience. When closing the refrigerator door 2, simply push the refrigerator door 2 close to the refrigerator body 1. When the magnetic sealing strip 201 approaches the refrigerator body 1, it will automatically attract the refrigerator door 2 onto the refrigerator body 1, completing the seal of the refrigerator body 1. Then, push the pressing plate 10 into the mounting box 6. The pressing plate 10 drives the squeezing plate 11 to move, and the second spring 1102 is compressed, pushing the handle 7 into the mounting box 6. Release the pressing plate 10, and the second spring 1102 returns to its original position, driving the squeezing plate 11 to move. The squeezing plate 11 squeezes the arc-shaped end of the positioning block 8 and pushes the positioning block 8 to move, so that the positioning block 8 enters the positioning groove 602, completing the locking of the handle 7 and hiding the handle 7 inside the mounting box 6, which is both aesthetically pleasing and space-saving.
