[0046] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0047] At present, the difficulty in opening the door has always been a pain point for refrigerator products. After refrigeration, the air inside the refrigerator shrinks as the internal temperature drops, forming a pressure difference between the inside and outside of the refrigerator, making it more difficult to open the refrigerator door. As the temperature difference between the inside and outside increases, the pressure difference also increases. Under the same door body, it is more difficult to open the door. As users' living standards improve, they sometimes store deep-sea fish, which puts forward new requirements for the refrigeration depth of refrigerators. Large-volume refrigerators are becoming more and more popular. The above situation combined will make the door opening force problem more prominent.

[0048] The related technology discloses a refrigerator, which includes: a box body, which defines a storage space; a door body, which is pivotally connected to the box body and is used for opening or closing the storage space; the refrigerator also includes an air pressure balance hole connected to the air flow inside and outside the storage space, and the air pressure balance hole is arranged on the door body; a handle, which is movably mounted on the door body and has an initial position and an open position; a guide device, which is arranged on the door body; a thrust piece, which is slidably connected to the guide device and can open or close the air pressure balance hole, one end of the thrust piece is transmission-connected to the handle, and the other end abuts against the box body, and the handle moves from the initial position to the open position to drive the thrust piece to slide to open the air pressure balance hole and transmit thrust to the box body. The refrigerator can open the door body with effort.

[0049] According to the related technology, when the handle is pulled, two air pressure balance holes and the air vents need to be connected at the same time to allow air to flow into the refrigerator, and the assisting effect on opening the door is poor.

[0050] Combination Figure 1-7 As shown, an embodiment of the present disclosure provides a handle assembly 01 for a refrigerator, including a handle box 1, a door opening device 2 and a ventilation device 4.

[0051] like Figure 1 and Figure 2 As shown, the handle box 1 encloses the installation space 11, including the opening 111; the ventilation device 4 is arranged outside the handle box 1, including a first end 41 and a second end 42, the first end 41 is connected to the inside of the refrigerator, and the second end 42 passes through the handle box 1 and is connected to the installation space 11; the door opening device 2 includes a connected blocking portion 20 and a handle 21, the blocking portion 20 is arranged in the installation space 11 and abuts against the second end 42, and the handle 21 is arranged at the opening 111 and can be turned over relative to the opening 111; wherein, when the handle 21 covers the opening 111, the blocking portion 20 abuts against the second end 42 to block the second end 42; when the handle 21 is turned toward the outside of the handle box 1 relative to the opening 111, it can drive the blocking portion 20 to move in a direction away from the second end 42, so that the blocking portion 20 is separated from the second end 42, and the installation space 11 and the inside of the refrigerator are connected.

[0052] The handle assembly 01 for a refrigerator provided by the embodiment of the present disclosure is adopted, and the handle 21 is arranged at the opening 111 of the installation space 11. In the initial state, the blocking portion 20 abuts against the second end 42, so that the installation space 11 and the interior of the refrigerator are not connected to each other, and the interior of the refrigerator is relatively closed. When the handle 21 is flipped toward the outside of the handle box 1 relative to the opening 111, the blocking portion 20 moves to separate the blocking portion 20 from the second end 42, and the air in the installation space 11 enters the interior of the refrigerator along the ventilation device 4, so that the installation space 11 is connected to the interior of the refrigerator to balance the air pressure inside and outside the refrigerator. When the handle 21 is pulled, only the blocking portion 20 and the second end 42 need to cooperate to reduce the air pressure difference between the inside and outside of the refrigerator to assist in opening the door, thereby improving the effect of assisting in opening the door.

[0053] Alternatively, if Figure 3 As shown, the door opening device 2 also includes a power assist component 3, which is arranged in the installation space 11 and connected to the handle 21 and the blocking portion 20; wherein, when the handle 21 is flipped toward the outside of the handle box 1 relative to the opening 111 by an external force, it can drive the power assist component 3 to move in a direction away from the second end 42, and then drive the blocking portion 20 to move in a direction away from the second end 42; when the external force is removed, the power assist component 3 generates a thrust on the blocking portion 20, so that the blocking portion 20 abuts against the second end 42.

[0054] When the handle 21 is flipped toward the outside of the handle box 1 relative to the opening 111 by an external force, the power assist assembly 3 can be driven to move in a direction away from the second end 42, thereby driving the blocking portion 20 to move in a direction away from the second end 42, so that the blocking portion 20 is separated from the second end 42, and the air in the installation space 11 enters the interior of the refrigerator along the ventilation device 4, so that the installation space 11 is connected with the interior of the refrigerator to balance the air pressure inside and outside the refrigerator. When the external force is removed, the power assist assembly 3 generates a thrust on the blocking portion 20, so that the blocking portion 20 abuts against the second end 42, so that the interior and exterior of the refrigerator are re-sealed to prevent the cold air inside the refrigerator from leaking out.

[0055] Alternatively, if Figure 2 As shown, a through hole 12 is provided on the side of the handle box 1 corresponding to the second end 42, and the power assist assembly 3 includes a push rod 31, one end of the push rod 31 is connected to the blocking portion 20, and the other end is passed through the through hole 12 and extends to the outside of the handle box 1, and can make linear reciprocating motion relative to the through hole 12; when the handle is flipped toward the outside of the handle box relative to the opening, the push rod moves in the direction away from the second end; when the handle is flipped from the outside of the handle box to the opening, the push rod moves in the direction close to the second end.

[0056] When the user drives the handle 21 to flip toward the outside of the handle box 1 relative to the opening 111, the push rod 31 is driven to move in a direction away from the second end 42, and the blocking portion 20 is away from the second end 42, so that the outside air flows from the installation space 11 along the ventilation device 4 from the second end 42 to the first end 41 to enter the refrigerator, balancing the air pressure inside and outside the refrigerator to help open the door. In addition, the handle 21 drives the push rod 31 to move, and the other end of the push rod 31 moves linearly along the through hole 12 in a direction away from the second end 42, and the part of the other end of the push rod 31 leaking out of the handle box 1 increases, pushing the refrigerator door body 001 and the box body open by a certain distance to help open the door.

[0057] When the user releases the handle 21 and the handle 21 returns to the state of covering the opening 111, the push rod 31 is driven to move in the direction close to the second end 42, and the blocking portion 20 is re-contacted with the second end 42, so that the inside and outside of the refrigerator are re-sealed to prevent the cold air inside the refrigerator from leaking out. In addition, the handle 21 drives the push rod 31 to move, and the other end of the push rod 31 moves linearly along the through hole 12 toward the direction close to the second end 42, and the push rod 31 gradually returns to the initial position, so that the refrigerator door 001 and the box body are closed.

[0058] Alternatively, if Figure 3 As shown, the handle 21 includes a first axle pin 5 arranged inside the handle box 1, and the power-assisting assembly 3 also includes a pendulum block 32. The pendulum block 32 is sleeved on the push rod 31 and is provided with an arc hole 321. The first axle pin 5 is slidably connected to the arc hole 321; wherein, when the handle 21 is flipped toward the outside of the handle box 1, the first axle pin 5 slides along the arc hole 321, driving the pendulum block 32 to move in a direction away from the second end 42, and the pendulum block 32 drives the push rod 31 to move in a direction away from the second end 42.

[0059] When the user drives the handle 21 to flip toward the outside of the handle box 1 relative to the opening 111, the push rod 31 and the swing block 32 are driven to move in a direction away from the second end 42. During the process of the handle 21 flipping, since the circular arc hole 321 and the first shaft pin 5 can move relative to each other, the first shaft pin 5 slides along the circular arc hole 321, driving the push rod 31 to move a first distance. When the handle 21 continues to flip, the swing block 32 is driven to move in a direction away from the second end 42, driving the push rod 31 to move a second distance. The setting of the swing block 32 allows the first shaft pin 5 to cooperate with the circular arc hole 321, so that the stroke of the push rod 31 is not only the stroke generated when the handle 21 moves, but also the stroke generated by the movement of the handle 21 along the circular arc hole 321, further increasing the movement distance of the push rod 31, so that the handle 21 can obtain a larger stroke when the structure and size are determined, thereby increasing the distance between the refrigerator door body 001 and the refrigerator body, so that the effect of power-assisted door opening is better.

[0060] Alternatively, if Figure 4 and Figure 5 As shown, the handle 21 is provided with an extension portion 22 relative to the pendulum block 32, the first axle pin 5 is passed through the extension portion 22 and partially extends into the arc hole 321, and when the handle 21 is flipped toward the outside of the handle box 1, the extension portion 22 drives the first axle pin 5 to move along the arc hole 321.

[0061] When the handle 21 is turned to the outside of the handle box 1, the extension 22 drives the first shaft pin 5 to move. The arc hole 321 includes a first end close to the bottom wall of the handle box 1 and a second end away from the bottom wall of the handle box 1. The first shaft pin 5 moves from the first end to the second end along the arc hole 321. In this process, the movement of the first shaft pin 5 drives the swing block 32 to move toward the through hole 12, so as to drive the push rod 31 to move toward the power-assisting position. The setting of the arc hole 321 makes the stroke of the push rod 31 not only the stroke generated when the handle 21 moves, but also the stroke generated when the first shaft pin 5 moves from the first end to the second end, which further increases the stroke of the push rod 31, so that the effect of power-assisting door opening is better.

[0062] Alternatively, if Figure 2 and Figure 3 As shown, the power assist assembly 3 also includes a reset member 33, which is sleeved on the push rod 31, and the push rod 31 is provided with a limiting protrusion 311, one end of the reset member 33 abuts against the limiting protrusion 311, and the other end abuts against the circumferential side wall of the through hole 12; wherein, when the handle 21 is acted upon by an external force and flipped toward the outside of the handle box 1, the reset member 33 generates a thrust on the push rod 31 toward the second end 42; when the external force is removed, the push rod 31 moves toward the second end 42 under the action of the thrust of the reset member 33, so that the blocking portion 20 abuts against the second end 42.

[0063] When the user opens the door, the user drives the handle 21 to move, the handle 21 drives the swing block 32 to move, the swing block 32 drives the push rod 31 to move, the push rod 31 moves along the through hole 12 in the direction away from the second end 42, the limit protrusion 311 moves with the push rod 31 in the direction close to the through hole 12, the reset member 33 arranged between the limit protrusion 311 and the through hole 12 is sleeved on the push rod 31, the distance between the limit protrusion 311 and the through hole 12 is reduced, the reset member 33 is squeezed, and the push rod 31 moves to push the refrigerator door body 001 away from the refrigerator body, completing the door opening step. The user releases the handle 21, and the squeezed reset member 33 stretches under the action of the restoring force and is about to return to the original state, the reset member 33 drives the push rod 31 to move toward the initial position, the push rod 31 drives the swing block 32 to move at the same time, and the swing block 32 drives the handle 21 back to the state of covering the opening 111, completing the door closing step.

[0064] Alternatively, if Figure 3 and Figure 6As shown, the handle box 1 includes a first support member 13 and a second support member 14. The first support member 13 is protruded from the bottom wall of the handle box 1 and is provided with a limiting hole 131. The push rod 31 is arranged in the limiting hole 131; the second support member 14 is protruded from the bottom wall of the handle box 1 and is rotatably connected to the handle 21.

[0065] The first support member 13 supports the push rod 31. One end of the push rod 31 is supported on the second end 42 of the ventilation device 4, and the other end is supported on the through hole 12. The first support member 13, the second end 42 and the push rod 31 abutment and the through hole 12 simultaneously support the push rod 31. The first support member 13, the limiting protrusion 311 and the reset member 33 are sequentially arranged in the direction close to the through hole 12, so that the push rod 31 moves in the direction away from the second end 42. The push rod 31 moves along the limiting hole 131 and the through hole 12, and the limiting protrusion 311 moves toward the position of the through hole 12 to squeeze the reset member 33. If the limiting protrusion 311 is located on the side of the first support member 13 away from the through hole 12, the push rod 31 cannot squeeze the reset member 33 when it moves, so that the reset member 33 cannot reset the push rod 31. In addition, the first support member 13 is provided so that the push rod 31 provided with the limiting protrusion 311 will not move in the direction away from the through hole 12 based on the initial position. The limiting protrusion 311 cooperates with the first support member 13 to play a blocking role.

[0066] The second support member 14 supports the handle 21. When the user drives the handle 21 to move, the handle 21 rotates relative to the second support member 14 to drive the pendulum block 32 and the push rod 31 to move. The setting of the second support member 14 makes the handle 21 more stable when flipping to the outside of the handle box 1 and returning.

[0067] Alternatively, if Figure 5 and Figure 6 As shown, the handle assembly 01 for the refrigerator further includes a second axle pin 6 , which is sequentially passed through the second support member 14 and the extension portion 22 for connecting the handle box 1 and the handle 21 .

[0068] When the user drives the handle 21 to flip toward the outside of the handle box 1, the extension portion 22 uses the second axle pin 6 as the rotation axis and rotates relative to the second support member 14, that is, the handle 21 rotates relative to the handle box 1. The setting of the second axle pin 6 makes the handle 21 rotate smoother relative to the handle box 1, and makes the subsequent power-assisting component 3 act on the refrigerator door body 001 or the refrigerator body more stable, so as to achieve a better power-assisting door opening effect.

[0069] Alternatively, if Figure 5As shown, the extension portion 22 includes a first extension portion 221 and a second extension portion 222, the first extension portion 221 is arranged on one side of the pendulum block 32; the second extension portion 222 is arranged on the other side of the pendulum block 32; the number of first axle pins 5 is equal to the number of extension portions 22, the first axle pin 5 includes a first sub-axle pin 51 and a second sub-axle pin 52, the first sub-axle pin 51 is passed through the first extension portion 221, and extends to one end of the arc hole 321; the second sub-connecting portion is passed through the second extension portion 222, and extends to the other end of the arc hole 321.

[0070] When the handle 21 is turned over to the outside of the handle box 1, the first extension part 221 and the second extension part 222 rotate along the second shaft pin 6, and the first extension part 221 and the second extension part 222 drive the swing block 32 to move with the handle 21 through the first sub-shaft pin 51 and the second sub-shaft pin 52, respectively. The movement of the swing block 32 drives the push rod 31 to move in a direction away from the second end 42 to assist in opening the door. When the handle 21 is turned over from the outside of the handle box 1 to the state of covering the opening 111, the first extension part 221 and the second extension part 222 drive the swing block 32 to move with the handle 21 through the first sub-shaft pin 51 and the second sub-shaft pin 52, respectively. The movement of the swing block 32 drives the push rod 31 to move in a direction close to the second end 42 to complete the door closing.

[0071] Alternatively, if Figure 5 As shown, the second support member 14 includes a first sub-support member 141 and a second sub-support member 142. The first sub-support member 141 is arranged on the outside of the first extension portion 221; the second sub-support member 142 is arranged on the outside of the second extension portion 222, and the second axle pin 6 is sequentially passed through the first sub-support member 141, the first extension portion 221, the second extension portion 222 and the second sub-support member 142.

[0072] The first sub-support member 141 and the second sub-support member 142 support the handle 21 at the same time. The first extension portion 221 and the second extension portion 222 use the second axle pin 6 as a rotation axis and rotate relative to the first sub-support member 141 and the second sub-support member 142 respectively to drive the pendulum block 32 and the push rod 31 to move. The arrangement of the first sub-support member 141 and the second sub-support member 142 makes the supporting force on the handle 21 more uniform and balanced, making the handle 21 more stable when moving, thereby achieving a better door opening effect.
