TECHNICAL FIELD
[0001] The present application relates to the technical field of handles, in particular to a handle assembly and a refrigerator. BACKGROUND
[0002] In the related art, the assist handle structure and the lock structure have been applied to refrigerators and freezers. However, generally, a refrigerator / freezer only has a lock structure or only has an assist handle structure, and only a few refrigerators / freezers have both assist function and locking function, and the lock structure and the assist handle structure are separately arranged, and the two separately realize their respective functions, and almost all of them lock after closing the door, and need to be unlocked before opening the door, and then open the door through the assist handle, which is very inconvenient to operate. SUMMARY
[0003] The present application aims to at least solve one of the technical problems existing in the prior art. To this end, the present application provides a handle assembly which can simultaneously realize the functions of assist and locking, and is convenient to operate.
[0004] The present application also provides a refrigerator having the above handle assembly.
[0005] According to the handle assembly of the first aspect of the present application, the handle assembly comprises:
[0006] a handle;
[0007] a connecting piece, one end of which is fixedly connected with the handle;
[0008] a fixing piece, which is hingedly connected to the connecting piece, and is provided with a clamping opening and an avoiding opening which are in communication, and the width of the avoiding opening is smaller than the width of the clamping opening;
[0009] a movable piece, which is slidingly installed on the fixing piece and can abut against the other end of the connecting piece;
[0010] a lock, which comprises a lock tongue, an elastic piece and a box body, the box body and the fixing piece are respectively installed on two components which are relatively rotatable, the box body has an abutting portion for abutting against the movable piece, the width of the lock tongue is smaller than the width of the avoiding opening, and the lock tongue is telescopically installed on the box body by the elastic piece and can extend into the clamping opening to lock the fixing piece;
[0011] a top block, which is fixedly connected to the movable piece, and the width of the top block is smaller than the width of the avoiding opening, and the top block can move with the movable piece to push open the lock tongue in the clamping opening to release the locking of the fixing piece by the lock tongue.
[0012] According to the handle assembly of the first aspect of the present application, at least the following beneficial effects are achieved:
[0013] When the door is closed, the latch is positioned within the latch of the fixing member. Because the width of the latch is smaller than the width of the clearance opening, the fixing member is locked by the latch and cannot move when the door is pulled. The fixing member is fixedly connected to the door, preventing the door from moving and keeping it closed, thus preventing children from opening the door or other abnormal opening situations. When it is necessary to open the door, pulling the handle causes the handle to rotate relative to the fixing member with the connecting member. The end of the connecting member pushes the movable member forward, causing the top block to push open the latch, causing the latch to retract from the latch and release the locking of the fixing member. Then, the top block continues to move forward into the clearance opening until the movable member abuts against the blocking part of the housing. At this point, the movable member is blocked by the housing and cannot move forward any further. The connecting piece continues to rotate and acts as a lever to move the fixing piece backward, thus initially opening the door. During the backward movement of the fixing piece, the top block is located in the bayonet and can enter the clearance slot. Therefore, the top block does not obstruct the movement of the fixing piece and prevents the bolt from entering the bayonet. This continues until the handle stops rotating and moves directly horizontally. At this point, the fixing piece and the moving piece will move with the entire door, thus opening the door. When closing the door, the handle moves with the door. At this time, the fixing piece moves forward and squeezes the bolt, causing the bolt to retract into the housing. When the door moves to the closed position, the bayonet of the fixing piece also moves above the bolt. The bolt, pushed by the elastic piece, extends into the bayonet, thus locking the fixing piece and locking the door. This handle assembly integrates power-assist and locking functions. When closing the door, it locks the door through the cooperation of the fixed parts and the lock. When opening the door, it assists in opening the door through the cooperation of the connecting parts, fixed parts, moving parts and the housing. At the same time, it unlocks the door through the cooperation of the top block and the lock tongue, making the operation quick and convenient.
[0014] According to some embodiments of the present invention, one of the fixed member and the movable member is provided with a slide rail, and the other is provided with a slide groove, and the movable member is slidably mounted on the fixed member by the cooperation of the slide rail and the slide groove.
[0015] According to some embodiments of the present invention, the movable member is provided with a bent portion opposite to the blocking portion, and the bent portion is equipped with a buffer block.
[0016] According to some embodiments of the present invention, the outer wall of the movable part is provided with a slot, and the top block is snapped and fixed in the slot.
[0017] According to some embodiments of the present invention, the end of the movable member is provided with a snap-fit position, and the end of the connector is provided with a snap-fit block, the snap-fit block being rotatably snapped into the snap-fit position.
[0018] According to some embodiments of the present invention, the snap-fit block is provided with arc-shaped portions on both sides, and the movable member is provided with a receiving portion that cooperates with the arc-shaped portions.
[0019] According to some embodiments of the present invention, the connector is provided with a rotating hole, the fixing member is provided with a mating hole, and the connector is rotatably connected to the fixing member by means of a rotating shaft passing through the rotating hole and the mating hole.
[0020] According to some embodiments of the present invention, the box body includes an inner box, the inner box being provided with a mounting cavity, and at least a portion of the locking tongue being disposed within the mounting cavity.
[0021] According to some embodiments of the present invention, the mounting cavity is equipped with a partition plate, the partition plate has a slot, the locking tongue includes a locking part, a sliding part and a limiting part, the locking part and the limiting part are located on both sides of the partition plate, the sliding part passes through the slot and connects the locking part and the limiting part, the elastic member is sleeved on the outside of the sliding part, and its two ends abut against the locking part and the partition plate.
[0022] According to some embodiments of the present invention, the locking part has an inclined end on the side facing the top block, and the height of the inclined end gradually decreases along the direction toward the top block.
[0023] According to some embodiments of the present invention, the handle assembly further includes a decorative element that covers the outside of the connector.
[0024] A refrigerator according to a second aspect of the present invention includes a handle assembly according to a first aspect of the present invention.
[0025] The refrigerator according to a second aspect embodiment of the present invention has at least the following beneficial effects:
[0026] When the refrigerator door is closed, the latch is positioned within the latch of the fixing component. Because the width of the latch is smaller than the width of the clearance opening, the fixing component is locked by the latch and cannot move when the refrigerator door is pulled. The fixing component is fixedly connected to the door, preventing the door from moving and keeping it closed, thus preventing children from opening the door or other abnormal opening situations. When it is necessary to open the door, pulling the handle causes the handle to rotate relative to the fixing component with the connecting component. The end of the connecting component pushes the movable component forward, causing the top block to push open the latch, causing the latch to retract from the latch and release the lock on the fixing component. Then, the top block continues to move forward into the clearance opening until the movable component abuts against the stop part of the refrigerator body. At this point, the movable component is blocked by the refrigerator body and cannot move forward any further. The handle and connecting parts continue to rotate, acting as a lever to move the fixing parts backward, thus initially opening the door relative to the housing. During the backward movement of the fixing parts, the top block, located in the bayonet and able to enter the clearance slot, does not obstruct the movement of the fixing parts and prevents the latch from entering the bayonet until the handle stops rotating and moves directly horizontally. At this point, the fixing and moving parts will move with the door as a whole, thus opening the door. When closing the door, the handle moves with the door, and the fixing parts move forward, squeezing the latch and causing it to retract into the housing. When the door moves to the closed position, the bayonet of the fixing parts also moves above the latch, and the latch, pushed by the elastic part, extends into the bayonet, thus locking the fixing parts and locking the door. This handle assembly integrates power-assist and locking functions. When closing the door, it locks the door through the cooperation of the fixed parts and the lock. When opening the door, it assists in opening the door through the cooperation of the connecting parts, fixed parts, moving parts and the housing. At the same time, it unlocks the door through the cooperation of the top block and the lock tongue, making the operation quick and convenient.

[0053] In the description of this invention, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.
[0054] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.
[0055] In related technologies, assisted handle structures and locking structures have been applied to refrigerators and freezers. However, typically, a refrigerator / freezer only has a lock structure or only an assisted handle structure. The few refrigerators / freezers that combine both assisted and locking functions have separate lock and assisted handle structures, each performing its own function independently. Furthermore, they almost always lock only after the door is closed, requiring unlocking before opening via the assisted handle, which is inconvenient. For many large refrigerators / freezers, opening the door requires considerable force, making it difficult and necessitating assistance. Given the large size of refrigerators, a locking function is also needed to prevent children from accidentally opening the door and entering. Additionally, for deep-freeze refrigerators / freezers with low temperatures, the large temperature difference between the inside and outside creates a large pressure difference, making opening difficult and requiring assistance. Moreover, deep-freeze refrigerators require excellent sealing; adding a locking mechanism ensures this sealing and prevents cold leakage or frost buildup.
[0056] Therefore, the present invention proposes a handle assembly that can simultaneously provide assistance and locking functions, and is easy to operate.
[0057] Reference Figures 1 to 4 This invention provides a handle assembly that simultaneously assists in opening and locking doors. It can be applied to the doors of refrigerators or freezers, and also to the doors of other appliances, such as dishwashers, cabinets, bedroom doors, or other types of doors. Taking a refrigerator as an example, the handle assembly is described in detail below: The handle assembly includes a handle 100, a connector 200, a fixing member 300, a movable member 400, a top block 500, and a lock 600. The handle 100 can be rod-shaped or other shapes, and can be fixedly connected to one end of the connector 200 by bolts or snap-fit connections. The fixing member 300 can be fixedly installed to the refrigerator door 700 by bolts or snap-fit connections, thus allowing the fixing member 300 to move with the door 700. One end of the fixing member 300 is hinged to the middle of the connector 200. The connector 200 is rotatable relative to the fixed member 300. The fixed member 300 may be provided with a limit block 350, which is used to limit the connector 200 from rotating too much. The end of the fixed member 300 away from the connector 200 is provided with a bayonet 310 and a clearance opening 320, the width of the clearance opening 320 being smaller than the width of the bayonet 310. The movable member 400 is slidably mounted on the fixed member 300, and the movable member 400 can abut against the other end of the connector 200.
[0058] Reference Figure 1 , Figure 8 and Figure 9 The lock 600 includes a latch 610, a resilient element 620, and a housing. The housing is fixedly mounted relative to the refrigerator body 800. For example, the housing can be fixedly installed on the outer wall of the body 800, or it can be fixedly installed on the wall where the refrigerator is mounted. The housing is provided with a stop 631 for blocking the movable part 400. The width of the latch 610 is smaller than the width of the clearance opening 320. The latch 610 is retractable and extendable to the housing via the resilient element 620 and can extend into the latch 310, thereby locking the fixing part 300. (See reference...) Figure 9 When the latch 610 is inside the latch 310, if the door 700 is pulled, the fixing member 300 moves with the door 700, causing the clearance opening 320 to tend to move toward the latch 610. Since the width of the latch 610 is greater than the width of the clearance opening 320, the latch 610 cannot enter the clearance opening 320, thus preventing the fixing member 300 from moving. Therefore, the door 700 is locked and cannot be opened.
[0059] The top block 500 is fixedly installed on the movable part 400, and the width of the top block 500 is smaller than the width of the clearance opening 320. The top block 500 can move between the latch 310 and the clearance opening 320 as the movable part 400 moves. Therefore, when the top block 500 moves forward with the movable part 400, the top block 500 can push open the locking tongue 610 located in the latch 310, thereby releasing the locking tongue 610 from locking the fixed part 300, allowing the door 700 to be opened.
[0060] Reference Figure 9 When the refrigerator door 700 is in the closed position, the latch 610 is located within the latch 310 of the fixing member 300. Since the width of the latch 610 is smaller than the width of the clearance 320, when the refrigerator door 700 is pulled, the fixing member 300 is locked by the latch 610 and cannot move, thus preventing the door 700 from moving and remaining closed. This prevents children from opening the door or other abnormal opening situations. When it is necessary to open the door 700, refer to... Figure 10 By pulling the handle 100, the handle 100 rotates relative to the fixed member 300 along with the connecting member 200. The end of the connecting member 200 pushes the movable member 400 forward, causing the top block 500 to push open the locking tongue 610, thus releasing the locking of the fixed member 300 from the latch 310. (Refer to...) Figure 11 Then, the top block 500 continues to move forward into the clearance opening 320 until the movable part 400 abuts against the blocking part 631 of the box body. At this point, the movable part 400 is blocked by the box body and cannot move forward any further. The handle 100 and the connecting part 200 continue to rotate and act as a lever to drive the fixed part 300 to move backward, thereby initially opening the door 700 relative to the box body 800. During the backward movement of the fixed part 300, since the top block 500 is located in the bayonet 310 and can enter the clearance opening 320, the top block 500 will not hinder the movement of the fixed part 300 on the one hand, and can prevent the latch 610 from entering the bayonet 310 on the other hand, until the handle 100 stops rotating and moves directly horizontally. Figure 12 At this time, the fixed part 300 and the movable part 400 will move together with the door body 700, as shown in the figure. Figure 13The door 700 is opened when the fixing member 300 is completely disengaged from the latch 610. When closing the door, the handle 100 moves with the door 700. At this time, the fixing member 300 moves forward and squeezes the latch 610, causing the latch 610 to retract into the housing. When the door 700 moves to the closed position, the latch 310 of the fixing member 300 also moves above the latch 610. The latch 610 is pushed into the latch 310 by the elastic member 620, thereby locking the fixing member 300 and thus locking the door 700. This handle assembly integrates power-assist and locking functions. When closing the door, the door 700 is locked by the cooperation of the fixing part 300 and the lock 600. When opening the door, the door is assisted by the cooperation of the connecting part 200, the fixing part 300, the moving part 400 and the housing. At the same time as opening the door, the door 700 is unlocked by the cooperation of the top block 500 and the lock tongue 610. The operation is quick and convenient.
[0061] Understandably, in order for the moving part 400 to slide smoothly on the fixed part 300, reference is made. Figure 2 , Figure 3 and Figure 5 In some embodiments of the present invention, one of the fixed member 300 and the movable member 400 is provided with a slide rail 410, and the other is provided with a slide groove 330. The movable member 400 is slidably mounted on the fixed member 300 through the cooperation of the slide rail 410 and the slide groove 330. For example, the fixed member 300 is provided with a slide groove 330 located on the outer edge of the fixed member 300, and the movable member 400 is provided with a slide rail 410, so that the movable member 400 can slide on the slide groove 330 of the fixed member 300 through the slide rail 410. Of course, the outer edge of the fixed member 300 may also be provided with a slide rail 410, and the movable member 400 may be provided with a slide groove 330 that cooperates with the slide rail 410, so that the movable member 400 can be smoothly slidably mounted on the fixed member 300. In some embodiments, the movable member 400 includes two sliders, which are slidably mounted on both sides of the fixed member 300, respectively.
[0062] Understandably, since the moving part 400 generates a relatively large impact force when it strikes the box, in order to improve the structural strength of the moving part 400 and reduce the damage caused by the impact between the moving part 400 and the box, refer to Figure 3 and Figure 4In some embodiments of the present invention, the movable member 400 is provided with a bent portion 420 opposite to the abutment portion 631. The bent portion 420 can improve the structural strength of the part of the movable member 400 that contacts the box body. Simultaneously, by installing a buffer block 430 on the bent portion 420, when the movable member 400 moves towards the box body and the bent portion 420 impacts the abutment portion 631 of the box body, the buffer block 430 can reduce the impact force between the bent portion 420 and the abutment portion 631, thus preventing excessive impact force from damaging the movable member 400 or the box body. Specifically, the buffer block 430 can be made of rubber, silicone, or other elastic materials.
[0063] Understandably, in order for the top block 500 to be securely connected to the moving part 400, refer to Figure 4 In some embodiments of the present invention, the outer wall of the movable member 400 is provided with a slot 460, and the top block 500 is engaged with the slot 460. Specifically, the top block 500 includes a body portion 510 and a connecting portion 520. The body portion 510 and the connecting portion 520 are fixedly connected. The body portion 510 is used to push open the locking tongue 610. The connecting portion 520 is generally frame-shaped and fits around the outer periphery of the movable member 400. At the same time, part of the connecting portion 520 is embedded in the slot 460, so that the connecting portion 520 can be stably installed on the movable member 400. When the movable member 400 moves, it can drive the top block 500 to move synchronously, preventing the top block 500 from easily loosening and falling off the movable member 400.
[0064] It should be noted that, in order for the connector 200 to push the movable part 400 forward to open the door, and then for the connector 200 to move the movable part 400 backward back to its original position, refer to... Figure 3 and Figure 4 In some embodiments of the present invention, the end of the movable member 400 is provided with a locking position, and the end of the connecting member 200 is provided with a locking block 220, which can be rotatably locked into the locking position. When it is necessary to open the door, the handle 100 is pulled, causing the connecting member 200 to rotate relative to the fixed member 300 and push the movable member 400 forward, thereby causing the movable member 400 to push open the latch 610 and open the door 700; when the door 700 is opened, during the process of the connecting member 200 returning to its original position, since the locking block 220 rotates and locks into the locking position, the connecting member 200 can drive the movable member 400 to move backward to its original position through the locking block 220, avoiding the movable member 400 from extending too far relative to the fixed member 300.
[0065] Understandably, in order for the connector 200 to better push the movable part 400 forward when it rotates relative to the fixed part 300, refer to... Figure 4In some embodiments of the present invention, the snap-fit block 220 is provided with arc-shaped portions 230 on both sides, and the movable member 400 is provided with a receiving portion 450 that cooperates with the arc-shaped portions 230. The receiving portion 450 is generally planar. When the connector 200 rotates, the outer wall of the receiving portion 450 and the outer wall of the arc-shaped portion 230 can fit tightly together, thereby better bearing the thrust of the connector 200. Specifically, when the connector 200 rotates relative to the fixed member 300, the arc-shaped portion 230 abuts against the receiving portion 450. The arc-shaped portion 230 slides on the surface of the receiving portion 450 and rotates at a certain angle relative to the receiving portion 450 to push the movable member 400 forward. During the process of pushing the receiving portion 450, the arc-shaped portion 230 can always maintain a close fit with the receiving portion 450, thereby making the force transmission between the connector 200 and the movable member 400 more stable, so that the movable member 400 can move more smoothly, and at the same time, the generation of abnormal noise can be reduced.
[0066] Understandably, in order for the connector 200 to rotate smoothly relative to the fixed part 300, reference is made. Figure 2 , Figure 4 and Figure 5 In some embodiments of the present invention, the connector 200 has a rotating hole 210 in its middle, and the fixing member 300 has a mating hole 340 that mates with the rotating hole 210. The connector 200 is rotatably connected to the fixing member 300 by passing through the rotating hole 210 and the mating hole 340 via a rotating shaft 240, thereby allowing the connector 200 to rotate smoothly relative to the fixing member 300. Of course, to allow the connector 200 to return to its original position, a torsion spring is sleeved on the outer side of the rotating shaft 240, and the end of the fixing member 300 is sleeved on the outer side of the torsion spring. Under the action of external force, such as when opening a door, the user pulls the handle 100. At this time, the handle 100 can rotate relative to the fixing member 300 around the axis of the rotating shaft 240 via the connector 200, simultaneously compressing the torsion spring. When the external force is released, under the action of the torsion spring, the handle 100 and the connector 200 will rotate back to their original positions.
[0067] Understandably, in order for the locking tongue 610 to extend and retract within the housing, refer to... Figure 2 and Figure 9In some embodiments of the present invention, the box body includes an inner box 630 and an outer box. The inner box 630 is disposed inside the outer box, and the abutment 631 is located at the end of the outer box. The inner box 630 is provided with a mounting cavity, and the locking tongue 610 is at least partially disposed in the mounting cavity. An elastic member 620 is installed in the mounting cavity. Under the action of the elastic member 620, the locking tongue 610 can partially extend out of the mounting cavity and enter the bayonet 310. The outer box is fixed to the outer wall of the refrigerator body 800, or can be fixedly installed on the wall of the refrigerator mounting position. The inner box 630 is fixed inside the outer box, thereby enabling the box body to be fixed. At the same time, the outer box can protect and hide the locking tongue 610, making the structure of the lock 600 more concealed.
[0068] Understandably, referring to Figure 9 In some embodiments of the present invention, a partition 632 is installed in the mounting cavity. The partition 632 has a slot 633, which can be U-shaped or other shapes. The locking tongue 610 passes through the slot 633 of the partition 632. The locking tongue 610 has a locking part 611, a sliding part 612, and a limiting part 613. The locking part 611 cooperates with the bayonet 310 to lock the fixing member 300. The two ends of the sliding part 612 are connected to the locking part 611 and the limiting part 613 respectively. The sliding part 612 and the limiting part 613 are generally cylindrical. The outer diameter of the sliding part 612 is smaller than the width of the slot 633, and the outer diameter of the limiting part 613 is larger than the width of the slot 633. The sliding part 612 passes through the slot 633. The locking part 611 and the elastic member 620 are located on one side of the partition 632. The elastic member 620 can be a compression spring. The compression spring is sleeved on the outside of the sliding part 612 and its two ends abut against the locking part 611 and the partition 632 respectively. The limiting part 613 is located on the other side of the partition 632. When the top block 500 moves forward, the locking part 611 is pushed downward by the top block 500. At this time, the locking part 611 moves toward the partition 632, and the compression spring is compressed. When the top block 500 moves away from the locking part 611, the locking part 611 can move away from the partition 632 under the action of the compression spring.
[0069] Understandably, in order to make it easier for the locking part 611 to move toward the partition 632 when the top block 500 moves forward, refer to Figures 6 to 9In some embodiments of the present invention, the locking part 611 is further provided with an inclined end, which is located on the side of the locking part 611 facing the bolt 610, and the height of the inclined end gradually decreases along the direction towards the bolt 610. When it is necessary to open the door 700, pushing the handle 100 causes the connecting member 200 to rotate, which in turn pushes the movable member 400 forward. The movable member 400 drives the top block 500 forward and abuts against the inclined end of the locking part 611. When the top block 500 continues to move forward, the top block 500 can move along the surface of the inclined end and apply a vertical component force to the locking part 611, thereby allowing the locking part 611 to disengage from the latch 310, making the movement of the bolt 610 smoother. Of course, the main body 510 of the top block 500 may also be provided with a mating end 511. The mating end 511 is provided with an inclined surface that mates with the surface of the inclined end. Therefore, when the main body 510 abuts against the locking part 611, surface contact can be achieved through the mating end 511 and the inclined end, thereby making the force distribution of the top block 500 and the locking tongue 610 more uniform, thus further improving the smoothness of the movement of the locking tongue 610.
[0070] It is understandable that connector 200 is connected to movable part 400, fixed part 300, and handle 100. Each connection point has numerous structural components. To conceal these connections and improve the aesthetics of the handle assembly, [following the provided text]... Figure 2 In some embodiments of the present invention, the handle assembly further includes a decorative element that covers the outside of the connector 200, thereby preventing external objects from affecting the rotation of the components at each connection point of the connector 200, improving the reliability of the connection between the connector 200 and the components, and simultaneously concealing the connector 200 to enhance the aesthetics of the handle assembly. Of course, the decorative element may also include a first decorative element 110 and a second decorative element 120. The first decorative element 110 covers the outside of the connector 200, and the second decorative element 120 covers the outside of the fixed element 300 and the movable element 400, thereby making the overall handle assembly more aesthetically pleasing, compact, and better concealed.
[0071] The refrigerator according to a second aspect of the present invention can be a deep-freezing refrigerator or a regular refrigerator. It includes a door 700, a cabinet 800, and a handle assembly according to the first aspect of the present invention. One end of the door 700 is hinged to the cabinet 800, and the other end of the door 700 is connected to the cabinet 800 via the handle assembly. The handle assembly has the function of assisting in opening the door and also has the function of locking the door 700.
[0072] Because the refrigerator uses the aforementioned handle assembly, when the door 700 is closed, the latch 610 is located within the latch 310 of the fixing member 300. Since the width of the latch 610 is smaller than the width of the clearance 320, when the refrigerator door 700 is pulled, the fixing member 300 is locked by the latch 610 and cannot move, thus preventing the door 700 from moving and remaining closed. This prevents children from opening the door or other abnormal opening situations. When it is necessary to open the door 700, the handle 100 is pulled. The handle 100 rotates relative to the fixed member 300 along with the connector 200. The end of the connector 200 pushes the movable member 400 forward, causing the top block 500 to push open the locking tongue 610, thus releasing the locking of the fixed member 300 from the latch 310. Then, the top block 500 continues to move forward into the clearance opening 320 until the movable member 400 abuts against the blocking part 631 of the housing. At this point, the movable member 400 is blocked by the housing and cannot move forward any further. As component 200 continues to rotate, it acts as a lever to move component 300 backward, thus initially opening the door 700 relative to the housing 800. During the backward movement of component 300, because top block 500 is located in latch 310 and can enter clearance 320, top block 500 does not obstruct the movement of component 300, and at the same time prevents latch 610 from entering latch 310, until handle 100 stops rotating and moves directly horizontally. At this point, component 300 and movable component... 400 will move along with the door body 700 as a whole, thereby opening the door body 700; when closing the door, the handle 100 moves with the door body 700, at which time the fixing member 300 moves forward and squeezes the latch 610, causing the latch 610 to retract into the housing. When the door body 700 moves to the closed position, the latch 310 of the fixing member 300 also moves above the latch 610. The latch 610 is pushed into the latch 310 by the elastic member 620, thereby locking the fixing member 300, and thus locking the door body 700. This handle assembly integrates power-assist and locking functions. When closing the door, the door 700 is locked by the cooperation of the fixing part 300 and the lock 600. When opening the door, the door is assisted by the cooperation of the connecting part 200, the fixing part 300, the moving part 400 and the housing. At the same time as opening the door, the door 700 is unlocked by the cooperation of the top block 500 and the lock tongue 610. The operation is quick and convenient.
[0073] It should be noted that the refrigerator door 700 typically has a large vertical dimension, therefore the handle 100 usually has a relatively long vertical length on the door 700. This is to ensure more even force distribution on both ends of the handle 100 along the vertical direction and to improve the locking capability of the handle assembly. (Refer to...) Figure 1 and Figure 2In some embodiments of the present invention, two connectors 200 are provided, which are connected to the two ends of the handle 100 along the vertical direction. Two locks 600 are also provided accordingly. Each connector 200 is connected to the corresponding lock 600 through a corresponding fixing member 300 and a movable member 400. Alternatively, only one lock 600 may be provided as needed. For example, one connector 200 may be connected to the lock 600 through a corresponding fixing member 300 and a movable member 400, while the other connector 200 may not have a corresponding lock 600. In this case, both ends of the handle assembly have the function of assisted opening, but only one end has the locking function, thus meeting different usage requirements.
[0074] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
