[0045] like Figures 1-10 As shown, this application embodiment provides a door opening device for opening a door 5 at the opening of a box (not shown). The door 5 has a mounting groove. The door opening device includes a rotating handle 1 and a push rod assembly 2. The rotating handle 1 is rotatably disposed in the mounting groove of the door 5. The rotating handle 1 includes a rotating assembly 11 and a door handle 12 slidably connected to the rotating assembly 11. The door handle 12 includes a first state of covering the mounting groove and a second state of moving out of the mounting groove. The push rod assembly 2 is disposed in the mounting groove of the door 5. The push rod assembly 2 is linked with the rotating assembly 11 of the rotating handle 1 to apply assistance to the box to open the door 5 when the rotating handle 1 is rotated.

[0046] In this application, by sliding the door handle 12 to the second state, the door handle 12 moves out of the mounting groove and forms a latch position between the door handle 12 and the mounting groove. By turning the door handle 12, the rotating handle 1 is driven to rotate, so that the rotating component 11 of the rotating handle 1 drives the top rod component 2 to apply assistance to the cabinet to open the cabinet door 5. Normally, the door handle 12 can be slid to the first state to cover the mounting groove. It can not only provide assistance when opening the cabinet door 5, but also adopt a hidden design to improve the flatness of the refrigerator's outer surface and the user experience.

[0047] Specifically, the door handle 12 is switched between the first state and the second state by sliding. When the door handle 12 is in the first state, the door handle 12 just covers the mounting groove of the cabinet door 5, so that the surface of the cabinet door 5 is flat. When it is necessary to open the cabinet door 5 by the assisted manner, the door handle 12 is slid to the second state, the door handle 12 is separated from the mounting groove, and then a hand holding position is formed between the door handle 12 and the mounting groove. The hand can be held in the hand holding position to pull the rotary handle 1, the rotary assembly 11 of the rotary handle 1 is linked with the jacking rod assembly 2 to drive the jacking rod assembly 2 to apply a pushing force between the cabinet and the cabinet door 5, and the door is assisted to be opened.

[0048] In the related art, some assisted handles are designed in a naked manner to ensure that the hand holding position is large. However, the naked design makes the assisted handle protrude outside the cabinet door 5, which affects the flatness of the surface of the refrigerator. Some assisted handles are arranged in the mounting groove of the cabinet door 5 in a semi-hidden manner. A hand holding position still needs to be reserved between the assisted handle and the mounting groove. If the reserved hand holding position is wide, a large groove exists on the surface of the cabinet door 5. If the reserved hand holding position is small, it is inconvenient to hold the fingers in the hand holding position and inconvenient to rotate the assisted handle. In the present application, the rotary handle 1 is arranged as the rotary assembly 11 and the door handle 12. The rotary assembly 11 is rotatably arranged in the mounting groove of the cabinet door 5. The door handle 12 is slidably connected with the rotary assembly 11. The door handle 12 is switched between the first state and the second state by sliding. When the door handle 12 is in the first state, the door handle 12 just covers the mounting groove of the cabinet door 5, so that the surface of the cabinet door 5 is flat and no groove exists. When it is necessary to rotate the rotary handle 1, the door handle 12 is first slid to the second state, a large hand holding position is formed between the door handle 12 and the mounting groove, the fingers are conveniently held in the hand holding position and conveniently apply force, and the rotary handle 1 is rotated to open the cabinet door 5.

[0049] Optionally, a traction part can be arranged on the door handle 12 in the present application. Specifically, the traction part can be a small groove or a pull rod. The door handle 12 is pulled from the first state to the second state by inserting the fingers into the groove or pulling the pull rod, so that a hand holding position is formed between the door handle 12 and the mounting groove. After the cabinet door 5 is closed, the door handle 12 is restored to the first state by pressing the door handle 12.

[0050] In some embodiments, the door opening device further comprises a locking assembly 3 arranged in the mounting groove. The locking assembly 3 comprises a locking part 31 and a control button 32. The locking part 31 is used to lock the door handle 12, so that the door handle 12 is in the first state. The control button 32 is used to release the locking of the door handle 12 by the locking part 31.

[0051] As Figure 6As shown, in the present application, by setting the locking assembly 3 in the installation groove, the locking part 31 of the locking assembly 3 is used to lock the door handle 12, so that the door handle 12 is kept in the first state, that is, to ensure the flatness of the surface of the box door 5; as Figure 7 As shown, when it is needed to open the box door 5, the control button 32 is controlled to release the locking of the door handle 12 by the locking part 31, so that the door handle 12 is in the active state, and the door handle 12 can be slid to the second state, and the subsequent door opening operation is completed.

[0052] In some embodiments, the door opening device further comprises a pre-embedded box 4 arranged in the installation groove, and the rotating handle 1, the top rod assembly 2 and the locking assembly 3 are arranged on the pre-embedded box 4.

[0053] As Figure 2 and 10 As shown, in the present application, the rotating assembly 11 is rotatably arranged in the pre-embedded box 4 through the rotating shaft 114, the rotating handle 1, the top rod assembly 2 and the locking assembly 3 are integrated in the pre-embedded box 4 by arranging the pre-embedded box 4 in the installation groove of the box door 5, so that the whole door opening device becomes a whole, and then is assembled into the installation groove of the box door 5, facilitating the assembly and disassembly of the whole door opening device.

[0054] Alternatively, of course, the door opening device can also have no pre-embedded box 4, and the rotating handle 1, the top rod assembly 2 and the locking assembly 3 are assembled in the installation groove respectively, which can also provide assistance when opening the box door 5, and ensure the flatness of the surface of the box door 5.

[0055] In some embodiments, the pre-embedded box 4 is provided with a mounting boss 41, the mounting boss 41 is provided with a first insertion slot 42, the first insertion slot 42 is provided with a first elastic part 43, and the door handle 12 is provided with a first insertion rod 121 for inserting into the first insertion slot 42 and abutting against the first elastic part 43; the first elastic part 43 is used to push the door handle 12 out to the second state after the control button 32 releases the locking of the door handle 12 by the locking part 31.

[0056] As Figure 5As shown in this application, the first elastic element 43 is a spring and fixed in the first slot 42. The first slot 42 on the door handle 12 can be inserted into the first slot 42 and abut against the first elastic element 43. When the door handle 12 is in the first state, the first elastic element 43 is in a compressed state. When the control button 32 releases the locking member 31 from limiting the door handle 12, the door handle 12 is popped out by the first elastic element 43, so that the door handle 12 automatically slides to the second state without having to manually pull the door handle 12 out to the second state, further improving the convenience of operation. When the cabinet door 5 is closed, the first insert rod 121 is inserted into the first slot 42 again and abuts against the first elastic element 43. The locking member 31 limits the door handle 12 to maintain the first state, ensuring the flatness of the cabinet door 5.

[0057] In some embodiments, the door handle 12 is provided with a through hole 122 along the depth direction of the mounting groove, the control button 32 passes through the through hole 122, the mounting boss 41 is provided with a second slot 44, the second slot 44 is provided with a second elastic member 45, the control button 32 is provided with a second insert 321 that is slidably disposed in the second slot 44, the second insert 321 abuts against the second elastic member 45, so that the control button 32 partially protrudes outside the through hole 122 when the door handle 12 is in the first state.

[0058] like Figure 2 , 6 As shown in Figure 8, in this application, the control button 32 passes through the through hole 122 on the door handle 12 and can move within a certain range along the depth direction of the mounting groove. When the door handle 12 is in the first state, the second insert 321 of the control button 32 is in contact with the second elastic member 45 in the second slot 44. The second elastic member 45 is in a compressed state, so that the control button 32 can partially protrude from the outside of the door handle 12, making it convenient to press the control button 32. When the control button 32 is pressed, the control button 32 moves toward the inside of the mounting groove, releasing the locking member 31 from limiting the door handle 12.

[0059] In some embodiments, the door handle 12 is provided with a first locking part 123 on the side facing the pre-embedded box 4. The locking member 31 includes: a slider 311, which is slidably disposed on the mounting boss 41 along the first direction X, and a second locking part 3111 for locking the first locking part 123 is provided on the slider 311; and a third elastic member 312, which is disposed between the slider 311 and the mounting boss 41, so that the second locking part 3111 is kept locked with the first locking part 123; when the control button 32 slides toward the inside of the mounting groove, it can push the slider 311 to slide along the first direction X, so that the second locking part 3111 disengages from the first locking part 123; wherein, the first direction X is perpendicular to the depth direction of the mounting groove.

[0060] In the application, the sliding block 311 can slide on the mounting boss 41 in the first direction X, and the third elastic member 312 applies an elastic pushing force to the sliding block 311, so that the sliding block 311 is located at one end of the first direction X, at this time, the second locking part 3111 of the sliding block 311 and the first locking part 123 of the door handle 12 are engaged with each other to complete locking; when the control button 32 slides towards the inside of the mounting groove, the sliding block 311 is squeezed to slide in the first direction X, so that the second locking part 3111 of the sliding block 311 and the first locking part 123 of the door handle 12 are separated, and the locking and limiting of the door handle 12 are released.

[0061] As shown in Figure 2 Specifically, the sliding block 311 is provided with a movable hole 3112, the control button 32 has a pressing part 322 and a wedge surface 323 away from the pressing part 322, when the control button 32 slides towards the inside of the mounting groove, one end of the wedge surface 323 is inserted into the movable hole 3112 and is squeezed by the wedge surface 323 and the edge of the movable hole 3112, the direction is changed by the wedge surface 323, so that the sliding block 311 moves towards the third elastic member 312, and then the second locking part 3111 of the sliding block 311 and the first locking part 123 of the door handle 12 are separated, the door handle 12 in the limiting state is slid to the second state under the action of the first elastic member 43, the control button 32 is reset under the elastic force of the second elastic member 45 and is separated from the sliding hole of the sliding block 311, the sliding block 311 is reset under the elastic force of the third elastic member 312, and waits for the next locking of the door handle 12.

[0062] In the application, the first locking part 123 and the second locking part 3111 respectively include locking hooks, the locking hooks of the first locking part 123 and the second locking part 3111 are engaged with each other to complete locking and limiting, the first locking part 123 and the second locking part 3111 also respectively include transition arc surfaces adjacent to the locking hooks, when the door handle 12 is pressed into the mounting groove, the two transition arc surfaces are squeezed to push the sliding block 311 to slide towards the third elastic member 312, when the door handle 12 slides to the first state, the two transition arc surfaces are separated, and the two locking hooks are engaged with each other to complete locking of the door handle 12.

[0063] As shown in Figure 8As shown, specifically, when the first locking portion 123 of the door handle 12 is separated from the second locking portion 3111 of the sliding block 311, the door handle 12 is in the active state and slides to the second state under the action of the first elastic member 43, at this time, the transition arc surfaces of the first locking portion 123 and the second locking portion 3111 are kept in abutment, and under the action of the pushing force of the third elastic member 312, the transition arc surface of the second locking portion 3111 exerts a certain pushing force on the transition arc surface of the first locking portion 123, so that the rotating assembly 11 of the rotating handle 1 rotates a certain angle towards the opening direction, and the top rod assembly 2 is driven by the rotating assembly 11 to exert a certain pushing force on the cabinet door 5, which is insufficient to separate the cabinet door 5 from the cabinet, but can check whether the door handle 12 is closed in place, if the door handle 12 is not pressed into the mounting groove to the first state, the end of the top rod assembly 2 abuts against the cabinet, so that a gap is left between the cabinet and the cabinet door 5, and a pressure difference cannot be formed inside and outside the cabinet door 5, so that the closing of the cabinet door 5 cannot be realized, thereby playing a role of checking whether the door handle 12 is closed in place. Only when the door handle 12 is fully slid to the first state and the limit is reached, the rotating assembly 11 of the rotating handle 1 will be in the initial state, and the top rod assembly 2 is also in the initial state, ensuring that the cabinet door 5 is closed in place.

[0064] In some embodiments, the mounting boss 41 is provided with a limiting portion 46 for limiting the control button 32, for preventing the control button 32 from being separated from the mounting boss 41.

[0065] As shown in Figure 2 and 5 In the present application, the control button 32 is limited by the limiting portion 46 on the mounting boss 41, so that the control button 32 only moves within a certain range and does not separate from the mounting boss 41.

[0066] In some embodiments, the rotating assembly 11 is provided with a sliding groove 111 at one end towards the door handle 12, and the door handle 12 is provided with a sliding lug 124 at one end towards the rotating assembly 11, the sliding lug 124 is slidingly arranged in the sliding groove 111, so that the door handle 12 is switched between the first state and the second state.

[0067] As shown in Figures 3-4 In the present application, the sliding lug 124 of the door handle 12 is slidingly arranged in the sliding groove 111 of the rotating assembly 11, so that the door handle 12 can slide relative to the rotating assembly 11, thereby realizing the switching of the door handle 12 between the first state and the second state.

[0068] Specifically, when the rotating assembly 11 of the rotating handle 1 is in the initial state, i.e., the cabinet door 5 is in the closed state, the extension direction of the sliding groove 111 is the depth direction of the mounting groove, and the door handle 12 slides along the depth direction of the mounting groove, so that a larger hand holding position between the door handle 12 and the mounting groove can be formed in the shortest distance. Alternatively, the extension direction of the sliding groove 111 can also be arranged at an angle with the depth direction of the mounting groove, and the door handle 12 slides along the sliding groove 111 while moving away from the mounting groove and approaching the rotating assembly 11, thereby increasing the gap width between the door handle 12 and the mounting groove, and facilitating the hand to be held in the hand holding position between the door handle 12 and the mounting groove.

[0069] In some embodiments, a strip-shaped groove 112 is arranged on the inner side wall of the sliding groove 111 along the extension direction of the sliding groove 111, and a sliding rod 125 is arranged on the sliding protrusion 124, and the end of the sliding rod 125 is slidingly arranged in the strip-shaped groove 112.

[0077] As shown in Figure 2 and 4 In the present application, the circular arc surface 212 of the push rod 21 cooperates with the concave surface 1131 of the driving portion 113, when the rotating assembly 11 rotates, the push rod 21 can move at a uniform speed, and when the push rod 21 is reset under the elastic force of the fourth elastic member 22, the rotating assembly 11 can be rotated and reset in the closing direction through the cooperation of the circular arc surface 212 and the concave surface 1131, so as to realize the automatic reset of the rotating assembly 11.

[0078] As shown in Figure 4 Specifically, the rotating assembly 11 adopts a hemispherical structure, so that the two sides of the sliding groove 111 have a reinforcing structure, which not only saves materials, but also facilitates molding and processing.

[0079] The door opening device is switched to the second state by sliding the door handle 12 out of the mounting slot and forming a handhold position between the door handle 12 and the mounting slot. The rotating handle 1 is rotated by pulling the door handle 12, so that the rotating assembly 11 of the rotating handle 1 drives the top rod assembly 2 to apply auxiliary opening force to the cabinet to assist the opening of the cabinet door 5. The door handle 12 can be slid to the first state to cover the mounting slot at ordinary times, which not only provides assistance when the cabinet door 5 is opened, but also adopts a hidden design to improve the flatness of the refrigerator surface and the user experience.

[0080] Figure 11 A structure schematic diagram of a door opening device provided by an embodiment of the application on a cabinet door is shown.

[0081] As shown in Figure 11 A refrigerator provided by an embodiment of the application includes a cabinet, a cabinet door 5 arranged at an opening of the cabinet to open or close the opening of the cabinet, and the door opening device described above.

[0082] The door opening device in the application is applied to a large-capacity refrigerator. A large-capacity refrigerator often has a larger door. Due to the existence of negative pressure inside the refrigerator, the increase of the door will cause the increase of the door opening force. When the cabinet door 5 is opened, the user not only needs to overcome the magnetic attraction force between the door seal and the cabinet, but also needs to overcome the pressure caused by the temperature difference between the inside and outside. The door opening device in the application not only plays a certain assisting role when the cabinet door 5 is opened, but also has the effect of facilitating the opening of the cabinet door 5. In addition, the door opening device adopts a hidden design, which can ensure the flatness of the refrigerator surface at ordinary times.
