Detailed Implementation

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Therefore, this utility model provides a French door structure for refrigerators, see [link / reference]. Figure 1 - Figure 4As shown, it includes a refrigerator body 1, a cabinet door 2 installed on the refrigerator body 1, a sealing strip 3 installed on the cabinet door 2, a pull hole 4 opened on the pull end face of the cabinet door 2, a protective component installed inside the cabinet door 2, the protective component includes a mounting groove 5, the mounting groove 5 is opened on the working surface of the cabinet door 2 around the sealing strip 3, the opening position of the mounting groove 5 is close to the opening of the pull hole 4, a long suction cup 6 is installed inside the mounting groove 5, fixing holes 7 are symmetrically opened on the inner arc surface of the mounting groove 5, a fixing short tube 8 is fixedly installed inside the fixing hole 7, an air inlet 9 is opened at the top of the fixing short tube 8, a through cavity is opened inside the fixing short tube 8, the air inlet 9 is connected to the through cavity, and the through cavity is connected to the long suction cup 6, and an auxiliary closing component is installed on the refrigerator body 1 and the cabinet door 2.

[0019] Inside the refrigerator body 1, a movable cavity 10 is provided around the pull hole 4. A through hole 11 is provided on the vertical inner wall surface of the pull hole 4 away from the refrigerator body 1. The through hole 11 communicates with the movable cavity 10. The two ends of the movable cavity 10 are connected to the fixed hole 7. One end of the fixed short tube 8 passes through the fixed hole 7 and is inserted into the interior of the movable cavity 10.

[0020] The movable cavity 10 is equipped with a movable frame 12. A pressing block 13 is fixedly connected to the movable frame 12 near the through hole 11. The pressing block 13 is inserted into the through hole 11. When the pressing block 13 is stationary, the pressing end is inserted into the pull hole 4, so that when a pulling force is applied to the cabinet door 2 through the pull hole 4, a pressing force is simultaneously applied to the pressing block 13.

[0021] Pull rods 15 are fixedly attached to the frame structure surfaces at both ends of the movable frame 12. The end of the pull rod 15 away from the movable frame 12 is inserted into the through cavity of the fixed short pipe 8. The end of the pull rod 15 inserted into the through cavity is connected to a sealing block 14. The cross-sectional radius of the sealing block 14 is the same as that of the through cavity.

[0022] A first limiting spring 16 is sleeved on the outside of the cross section of the pulling rod 15. One end of the first limiting spring 16 is connected to the moving frame 12, and the other end of the first limiting spring 16 is connected to the end of the fixed short tube 8.

[0023] When the first limiting spring 16 is in its natural state, the stationary position of the sealing block 14 completely covers the opening of the air inlet 9, and the frame of the moving bracket 12 is in contact with the vertical inner wall surface of the moving cavity 10 where the through hole 11 is located. When the sealing block 14 is pulled along with the pulling rod 15, the first limiting spring 16 is stretched and generates a reaction force. When the pressure on the pressing block 13 is removed, the reaction force of the first limiting spring 16 can reset the sealing block 14, facilitating the subsequent re-adsorption of the long strip suction cup 6.

[0024] On the vertical surface of the refrigerator body 1 where the cabinet door 2 is installed, a smooth patch 17 is fixed at the position covered by the long suction cup 6. The working area of ​​the smooth patch 17 can completely cover the working area of ​​the long suction cup 6. When the cabinet door 2 is closed, the long suction cup 6 is attached to the surface of the smooth patch 17, thereby increasing the resistance when the cabinet door 2 is opened and preventing the cabinet door 2 from being opened by children with less strength.

[0025] During operation, due to the structural design of the protective components, when a pulling force is applied to the cabinet door 2 through the pull hole 4, the puller's hand first comes into contact with the pressing block 13, and a pressing force is applied to the pressing block 13 during the pulling process. The pressing block 13 is subjected to force, causing the sealing block 14 to move away from the refrigerator body 1 along the moving cavity 10. At the same time, the pull rod 15 drives the sealing block 14 to move along the through cavity inside the fixed short tube 8. When the sealing block 14 disengages from the opening of the air inlet 9, air enters the through cavity inside the fixed short tube 8 through the air inlet 9 and enters the suction cavity of the long suction cup 6. The suction force disappears, and the long suction cup 6 disengages from the surface of the smooth patch 17, thereby removing the added resistance and facilitating the opening of the cabinet door 2. Since the pressing block 13 is hidden inside the pull hole 4, it prevents children from repeatedly pulling the cabinet door 2 out of curiosity, improving the protective effect and reducing potential dangers in the home.

[0026] Further, see Figure 1 , Figure 5 As shown, the auxiliary closing assembly includes a mounting cavity 18. Mounting cavities 18 are located at the upper and lower ends of the refrigerator body 1, near the hinge of the cabinet door 2. A mounting base 19 is installed at one end of the mounting cavity 18, and an electromagnet 21 is mounted on the mounting base 19. A structural hole 20 is located on the vertical surface of the refrigerator body 1 where it contacts the cabinet door 2, near the mounting cavity 18. The structural hole 20 communicates with the mounting cavity 18, and the electromagnet 21 is inserted into the structural hole 20. A fixing groove is located on the vertical surface of the cabinet door 2 where it contacts the refrigerator body 1, and a magnet 26 is installed inside the fixing groove. When the structural hole 20 is in operation, it generates magnetic force, which attracts the nearby magnet 26, providing a pulling force for the unclosed cabinet door 2 and ensuring its complete closure.

[0027] A pressure sensor 24 is installed inside the mounting cavity 18 at the end furthest from the mounting base 19. A telescopic hole 22 is provided on the vertical surface of the refrigerator body 1, near the structural hole 20, where it fits against the cabinet door 2. A limit rod 23 is installed inside the telescopic hole 22. One end of the limit rod 23 is inserted into the mounting cavity 18. A second limit spring 25 is fitted around the cross-section of the limit rod 23. One end of the second limit spring 25 is connected to the rod body of the limit rod 23, and the other end is connected to the pressure sensor 24. When the force applied by the second limit spring 25 to the pressure sensor 24 is continuously outside the preset range, the structural hole 20 activates and generates an adsorption force, attracting the nearby magnet 26 and causing the cabinet door 2 to close completely.

[0028] In its natural state, the active end of the limiting rod 23 extends outward through the telescopic hole 22. A sliding groove 27 is provided on the vertical surface of the cabinet door 2 that is in contact with the refrigerator body 1, near the magnet 26. When the cabinet door 2 approaches the refrigerator body 1, the active end of the limiting rod 23 moves along the opening of the sliding groove 27, preventing the end of the limiting rod 23 from scratching the cabinet door 2.

[0029] During operation, through the structural design of the auxiliary closing component, when the cabinet door 2 is pushed towards the refrigerator body 1 but not completely closed, the limit rod 23 will be squeezed by the refrigerator body 1 and move into the mounting cavity 18 along the telescopic hole 22. The second limit spring 25 is compressed and generates a reaction force. When the continuous force on the pressure sensor 24 for a certain period of time is not within the set threshold, the structural hole 20 generates a magnetic force and attracts the nearby magnet 26, causing the cabinet door 2 to rotate towards the refrigerator body 1, thus achieving the effect of completely closing the cabinet door 2.

[0030] In summary, this effectively addresses the existing problems faced by families with young children. Children, out of curiosity, pull on the refrigerator door, which not only consumes electricity but also poses a potential danger. Furthermore, when taking food and closing the door, children often apply too little force because they are holding items in their hands, resulting in the door not closing completely and increasing energy consumption due to prolonged door opening.
