Description

Technical Field

[0001] This invention relates to the field of refrigeration equipment technology, and particularly to refrigerators. Background Technology

[0002] A refrigerator has a cabinet and a door, which are connected by a magnetic or other structure to keep them closed. For example, a magnet on the door attracts the door to the cabinet, keeping the door in contact and thus closed. However, this connection also makes opening the door difficult. Related technologies use an assistive mechanism that extends a rod and presses against the cabinet to help open the door. This assistive mechanism can be located at the bottom or side of the door. The advantage of placing the assistive mechanism at the bottom is that it is not visible on the refrigerator's exterior, allowing for a concealed design and better aesthetics. However, the limited operating space at the bottom of the door restricts the structure of the assistive mechanism; for example, the handle has virtually no room to turn downwards, so it is generally designed to extend outwards.

[0003] In related technology, there is a refrigerator whose door can be opened and closed from either side (i.e., the right-hand side and the left-hand side). In this refrigerator structure, two cam mechanisms for engaging and disengaging the cabinet and door are mounted on the left and right sides of the door. (See reference...) Figure 19 As shown, if the assist mechanism is located at the bottom of the refrigerator door, the door rotates around the right side to open the left side. Since the left side requires a cam mechanism, the assist mechanism needs to be positioned slightly towards the center. Furthermore, to make the assist mechanism less strenuous, the push rod should be positioned towards the left, increasing the distance to the right-side pivot. Accordingly, the handle is located on the side of the push rod facing the door's centerline. When opening the door, the handle rotates from right to left (counter-clockwise as shown in the diagram), while opening the left side requires rotating the door from left to right (clockwise as shown in the diagram). These different rotation directions force the user to switch directions of force when opening the door, causing inconvenience. Summary of the Invention

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a refrigerator that can achieve a concealed design and improve ease of use.

[0005] According to a first aspect of the present invention, a refrigerator includes: a cabinet, a door, four hinges, and an assist mechanism. Each of the four corners of the door is connected to the cabinet via one of the hinges. The hinges allow either the left or right side of the door to engage and disengage from the cabinet. Each hinge includes a fixed member, a first pivot, and a movable member. The fixed member and the first pivot are connected to the cabinet, and the movable member is connected to the door. The movable member has a sliding groove, and the fixed member has a through hole. The first pivot passes through the through hole and is capable of sliding along the sliding groove. The opening of the sliding groove faces the cabinet. The sliding groove includes a first sliding section and a second sliding section. The first pivot moves in different directions in the first sliding section and the second sliding section. The opening of the sliding groove is located in the first sliding section. When the door is closed, the first pivots on both sides are held at the junction of the first and second sliding sections. When the door is opened on one side... When the door is closed, the door slides and the first pivot on the other side enters the tail end of the second sliding section, causing the door to rotate around the first pivot on the other side but restricting the sliding. The hinge also includes a roller assembly. The fixing member is provided with a guide portion. The roller assembly is installed at the bottom of the moving member and abuts against the guide portion. The guide portion is used to guide the movement of the roller assembly in the front-back direction. The guide portion includes a second inclined section, the front end of which is lower than the rear end of the second inclined section. The assist mechanism is located at the bottom of the door. The assist mechanism includes a handle, a transmission mechanism, and a push rod. The push rod is slidably disposed on the door. The transmission mechanism is used to amplify the power transmitted by the handle and continue to transmit it to the push rod. When the door is closed, the roller assembly is located behind the second inclined section. When the door is opened, the push rod abuts against the housing, causing one side of the door to open a certain distance, and causing the roller assembly to move forward past the rear end of the second inclined section.

[0006] The refrigerator according to an embodiment of the present invention has at least the following beneficial effects: When the push rod of the assist mechanism extends, causing the left door to open a certain distance, i.e., the right side of the door is at a predetermined distance from the edge of the cabinet opening, the roller assembly moves forward and has entered the second inclined section, i.e., the roller assembly has passed the highest point of the second inclined section and is located between the front end and the rear end of the second inclined section. Utilizing the inertia of the door opening and the gravity of the door, the roller assembly can continue to move along the second inclined section, thereby driving the door to rotate and realizing the opening action. The user can avoid the step of applying force to rotate the door from left to right, making it more convenient to use. In other words, the refrigerator of the present invention can achieve a hidden design, reduce the user's operating steps, and improve the user experience.

[0059] Reference Figure 1 As shown, an embodiment of the present invention provides a refrigerator whose door can be opened and closed on either side (i.e., the right-hand side and the left-hand side).

[0060] The refrigerator in this embodiment has a cabinet 1801 (see reference). Figure 18 The interior of the housing 1801 is divided into many vertically arranged refrigeration compartments, each with an opening at the front. The uppermost refrigeration compartment is equipped with a door 101 that can rotate horizontally. The opening can be opened and closed by rotating the door 101 around one side (i.e., the right-hand side or the left-hand side).

[0061] The refrigerator of this embodiment includes four hinges 201 (see reference). Figure 2 ), the four hinges 201 are respectively set at Figure 1 The diagram shows four A-regions, each equipped with one hinge 201. Two hinges 201 connect to the upper end of the door 101, two hinges 201 connect to the lower end of the door 101, two hinges 201 connect to the left side of the door 101, and two hinges 201 connect to the right side of the door 101. When the left side of the door 101 is opened, the two hinges 201 on the left side of the door 101 disconnect the door 101 from the housing 1801, while the two hinges 201 on the right side of the door 101 maintain the connection between the door 101 and the housing 1801. The door 101 can rotate around the two right-side hinges 201, thus opening and closing the housing opening.

[0062] Reference Figures 2 to 5As shown, the hinge 201 includes a fixed member 202, a first rotating shaft 301, and a movable member 203. The fixed member 202 and the first rotating shaft 301 are connected to the housing 1801 and remain relatively fixed to it. The movable member 203 is connected to the door 101 and remains relatively fixed to it. The fixed member 202 is provided with a first arc-shaped boss 302, and the movable member 203 is provided with a second arc-shaped boss 303. The first arc-shaped boss 302 and the second arc-shaped boss 303 are coaxially arranged with the first rotating shaft 301, that is, the rotation center of the first arc-shaped boss 302 and the rotation center of the second arc-shaped boss 303 are concentric with the rotation center of the first rotating shaft 301. The first arc-shaped boss 302 is located on the outer periphery of the second arc-shaped boss 303, so that the first arc-shaped boss 302 can guide the second arc-shaped boss 303 to rotate and achieve a limiting effect. The opening of the first arc-shaped boss 302 faces the door body 101. A sliding groove 304 is also provided on the movable part 203, and a through hole 609 is provided on the fixed part 202. The first rotating shaft 301 passes through the through hole 609 and can slide along the sliding groove 304. The opening of the sliding groove 304 faces the housing 1801. The second arc-shaped boss 303 is located along the periphery of the closed end of the sliding groove 304.

[0063] Reference Figure 4 As shown, it can be understood that the sliding groove 304 includes a first sliding section 401 and a second sliding section 402. The width of the first sliding section 401 matches the diameter of the first rotating shaft 301, and its trajectory matches the opening trajectory of the first rotating shaft 301. The second sliding section 402 extends outward at the tail end of the first sliding section 401, that is, there is a turning point between the first sliding section 401 and the second sliding section 402. The movement directions of the first rotating shaft 301 are different in the first sliding section 401 and the second sliding section 402.

[0064] Reference Figure 4 As shown, the outer surface of the second arc-shaped boss 303 includes a closing arc surface 403 and a revolving arc surface 404. (Refer to...) Figure 3 As shown, in the closed state, the first pivot 301 is located at the junction of the first sliding section 401 and the second sliding section 402, and the closing arc surface 403 matches the inner surface of the first arc-shaped boss 302. (Refer to...) Figure 5 As shown, in the open state, the first rotating shaft 301 on the rotating side is located at the end of the second sliding section 402, and the inner side of the first arc-shaped boss 302 matches the arc surface 404 of the revolving door.

[0065] For example, when the door is opened with the first pivot 301 on the left as the center, the first pivot 301 on the left slides into the tail end of the second sliding segment 402. The tail end of the second sliding segment 402 rotates in conjunction with the first pivot 301, resulting in the door body 101 rotating around the first pivot 301 on the left but restricting its sliding (see reference). Figure 5(as shown in the diagram); simultaneously, the first rotating shaft 301 on the right slides towards the opening of the sliding groove 304 on the right, and gradually disengages from the moving part 203 (refer to...). Figure 4 (The state shown).

[0066] To better achieve the position switching of the first rotating shaft 301 in the first sliding segment 401 and the second sliding segment 402, refer to Figure 3 As shown, the fixed member 202 is also provided with a sliding guide block 305, which is located inside the first arc-shaped boss 302. The movable member 203 is also provided with a sliding pressure block 306, which is used to slide and engage with the left or right side of the sliding guide block 305. By changing the positional relationship between the sliding guide block 305 and the sliding pressure block 306, the first rotating shaft 301 can be more stably held within the first sliding section 401 or the second sliding section 402.

[0067] Reference Figure 3 As shown, it can be understood that the sliding pressure block 306 is separated from the sliding guide block 305 and is arranged opposite to each other in the front-back direction. At this time, the first rotating shaft 301 is located at the junction of the first sliding section 401 and the second sliding section 402, and the door 101 is in the closed state.

[0068] Reference Figure 4 As shown, it can be understood that when the door opens, the door body 101 moves forward a certain distance, causing the first pivot 301 on the opening side to enter the first sliding section 401. That is, the door body 101 moves away from the sliding guide block 305 relative to the box body 1801, for example, to the left. Then, the sliding pressure block 306 abuts against the left side of the sliding guide block 305, and the outer surface of the sliding pressure block 306 slides along the outer surface of the sliding guide block 305. The sliding guide block 305 and the first pivot 301 work together on the door body 101, restricting the door body 101 in the left and right directions, thus making it less likely to fall off the box body 1801. When the door body 101 continues to rotate, both the first pivot 301 and the sliding guide block 305 on the opening side disengage from the door body 101, thereby realizing the opening of the door.

[0069] Reference Figure 5 As shown, it can be understood that when the door is opened, the door body 101 moves forward a certain distance, causing the first rotating shaft 301 on the rotating side to enter the tail end of the second sliding section 402. That is, the door body 101 moves away from the sliding guide block 305 relative to the box body 1801, for example, to the right. Then, the sliding pressure block 306 abuts against the right side of the sliding guide block 305. The outer surface of the sliding pressure block 306 slides along the outer surface of the sliding guide block 305. The sliding guide block 305 and the first rotating shaft 301 work together on the door body 101, so that the door body 101 rotates around the first rotating shaft 301. The door body 101 is not easy to wobble, and it ensures that the door body 101 and one side of the box body 1801 are always connected.

[0070] It should be noted that, in order to achieve the left and right door opening function, the refrigerator can also be equipped with other left and right door opening mechanisms. For example, the left and right door opening mechanism includes four hinges 201 connecting the cabinet 1801 and the door 101, each hinge 201 being respectively set at... Figure 1 In area A of the door, hinge 201 includes a fixing member 202, a first pivot 301, a third pivot, and a movable member 203. The fixing member 202 is provided with an arc-shaped guide rail, which includes two relatively parallel first extensions and second extensions, as well as a connecting part connecting the first extensions and the second extensions. The fixing member 202 and the arc-shaped guide rail are respectively provided with sliding grooves 304 facing the door body 101. The sliding groove 304 includes a first sliding section 401 along the longitudinal direction of the fixing member 202 and a second sliding section 402 at an angle to the first sliding section 401. The first sliding section 401 and the second sliding section 402 are connected. The first rotating shaft 301 and the third rotating shaft are fixedly mounted on the movable part 203. The first rotating shaft 301 is located inside the sliding groove 304 to enable the door 101 to rotate, and the third rotating shaft is located outside the sliding groove 304 to limit the arc-shaped guide rail. The distance between the first rotating shaft 301 and the third rotating shaft is equal to the width of the arc-shaped guide rail. When the door 101 is closed, the first rotating shaft 301 is located inside the sliding groove 304, and the third rotating shaft is located outside the sliding groove 304. When the first rotating shaft 301 and the third rotating shaft on one side of the door 101 disengage from the inner and outer sides of the arc-shaped guide rail, the first rotating shaft 301 on the other side moves to the innermost side of the sliding groove 304, that is, located in the second sliding section 402, and the first rotating shaft 301 and the third rotating shaft on the other side are located inside and outside the arc-shaped guide rail, respectively, and the door 101 opens.

[0071] Reference Figure 6 As shown, it can be understood that the embodiments of the present invention provide a power assist mechanism 601, referring to... Figure 1 As shown, the assist mechanism 601 is located in area B of the diagram, that is, at the bottom of the door body 101. The assist mechanism 601 helps the door body 101 overcome the initial resistance when opening, causing the door body 101 to move forward a certain distance, thereby allowing the first pivot 301 on the opening side to enter the first sliding section 401, and also allowing the first pivot 301 on the rotating side to enter the tail end of the second sliding section 402. For example, referring to… Figure 18As shown, the door 1801 has an outer shell, within which a resin component is sealed. The outer shell is made of painted steel sheet. The front end of the outer shell is bent inward to form the frame edge 1802 of the door opening. A sealing gasket 1803 is installed on the inner surface of the door 101 along its entire edge. This sealing gasket 1803 contains a magnet, which attracts the frame edge 1802 of the outer shell through its magnetic force, thereby keeping the sealing gasket 1803 in contact with the outer shell and thus keeping the door 101 closed. An assist mechanism 601 helps the user to use less force to allow the door 101 to break free from the magnetic force of the magnet and begin to move away from the frame edge 1802 of the outer shell. Region B is located in the lower part of the door 101, near the center. Figure 1 There are two assist mechanisms 601 shown, i.e., two regions B, with each assist mechanism 601 located within one region B. Each assist mechanism 601 is used to open the door 101 on the adjacent side. For example, the left-side assist mechanism 601 enables the left-side door 101 to open a certain distance, thereby allowing the door 101 to rotate about the right-side hinge 201.

[0072] It should be noted that, from Figure 1 From a certain perspective, hinge 201 and assist mechanism 601 are not exposed to the outside, therefore in Figure 1 Its outline is not shown; only its approximate location is indicated by dashed leader lines.

[0073] Reference Figures 6 to 10 As shown, in one embodiment, the assist mechanism 601 includes a handle 602, an assist rod 603, and a push rod 604. A second pivot 605 is provided on the assist rod 603, and the assist rod 603 is rotatably connected to the door body 101 at the second pivot 605. The second pivot 605 divides the assist rod 603 into a first rod portion 701 and a second rod portion 702. The handle 602 is connected to the first rod portion 701, and the second rod portion 702 is used to push the push rod 604 to move. The push rod 604 moves back and forth in a direction perpendicular to the door body 101, and the push rod 604 is used to abut against the sliding guide block 305.

[0074] It should be noted that in some other embodiments, the top rod 604 can also be used to directly abut against the box opening frame edge 1802 of the box body 1801.

[0075] Taking the user opening the left side of the door 101 as an example, when the user grasps the operating part of the left-side handle 602 and pulls it forward, the assist rod 603 is subjected to a force that tends to cause the assist rod 603 to rotate counterclockwise around the second pivot 605. Subsequently, the end of the second rod 702 pushes the push rod 604 toward the sliding guide block 305, and the push rod 604 applies pressure to the sliding guide block 305. Thus, the door 101 is subjected to a force that tends to cause the door 101 to rotate clockwise around the first pivot 301 on the right side. As a result, the left-side sealing gasket 1803 breaks free from the magnetic force of the magnet and begins to move away from the outer casing's frame edge 1802.

[0076] When handle 602 is pressed Figure 8 When the handle 602 is pulled to a certain angle and the push rod 604 is pushed back a certain distance relative to the second pivot 605, the door 101 is positioned a predetermined distance away from the edge 1802 of the refrigerator compartment 1801. In this state, if the handle 602 is pulled further toward the first pivot 301 on the rotation side, or if the door 101 is pulled, the door 101 rotates around the first pivot 301 on the rotation side. Thus, the opening of the refrigerator compartment 1801, previously closed by the door 101, is opened, allowing items to be placed or removed from the refrigerator.

[0077] like Figure 8 As shown, the distance from the point of force application on the handle 602 to the central axis of the second rotating shaft 605 is defined as L1, and the distance from the contact point between the assist rod 603 and the top rod 604 to the central axis of the second rotating shaft 605 is defined as L2. Therefore, distance L1 is greater than distance L2. Thus, according to the lever principle, a very small force can open the door 101 to a predetermined distance. Furthermore, the assist rod 603 is located at the bottom of the door 101, making it difficult to detect and resulting in a more consistent appearance.

[0078] Reference Figure 9 and Figure 10As shown, the first rod 701 includes a first connecting section 901 and a second connecting section 902. The first connecting section 901 and the second rod 702 are arranged in the same direction, i.e., both are arranged along the left-right direction. The two ends of the second connecting section 902 are respectively connected to the first connecting section 901 and the second rod 702. The first connecting section 901 is located on the rear side of the second rod 702. The handle 602 is installed on the first connecting section 901, so that the handle 602 can be placed further back, which facilitates the hidden design. The handle 602 is not easily exposed on the outside of the refrigerator, improving the uniformity of the refrigerator's appearance. If the handle 602 protrudes from the outer surface of the door 101 when the door is opened, the user's hand is located between the handle 602 and the door 101 when releasing the handle, which can easily cause a pinching problem. The solution of this embodiment, by setting the first connecting section 901 on the rear side of the second rod 702, can also prevent the handle 602 from protruding from the outer surface of the door 101, thereby achieving the anti-pinch function.

[0079] Reference Figures 6 to 10 As shown, the assist mechanism 601 also includes a first return spring 606. One end of the first return spring 606 is connected to the assist rod 603, and the other end is connected to the door body 101. The first return spring 606 has a deformed state and a natural state. When the door is closed, the first return spring 606 is in the natural state. When the door is opened, the user pulls the handle 602, and the assist rod 603 moves with the handle 602, causing the first return spring 606 to change to the deformed state. When the user releases the handle 602, the assist rod 603 returns to its original position under the action of the first return spring 606, and the first return spring 606 also changes from the deformed state to the natural state.

[0080] Reference Figures 6 to 12 As shown, the first return spring 606 can be a tension spring. One end of the tension spring is connected to the first rod 701, and the other end is connected to the door body 101. The tension spring is located on the side of the first rod 701 opposite to the direction of the pull handle 602. That is, when the user pulls the handle 602 forward, the tension spring is located behind the first rod 701. When opening the door, the user pulls the handle 602, and the handle 602 rotates forward relative to the door body 101. The assist rod 603 follows the movement of the handle 602, causing the tension spring to be extended. That is, the length of the tension spring changes from its original length to its extended length. The backward pulling force of the tension spring on the first rod 701 increases as the rotation angle of the assist rod 603 increases. When the user releases the handle 602, the first rod 701 is subjected to the backward pulling force of the tension spring, causing the assist rod 603 to rotate in the opposite direction and achieve reset. Correspondingly, the length of the tension spring changes from its extended length to its original length, and the tension spring returns to its natural state.

[0081] It should be noted that the tension spring can also be connected to the second rod 702, in which case the tension spring is located in front of the second rod 702. When opening the door, the user pulls the handle 602, and the second rod 702 stretches the tension spring backward. When the user releases the handle 602, the second rod 702, due to the forward tension of the tension spring, causes the assist rod 603 to rotate in the opposite direction and return to its original position.

[0082] It is understandable that the first return spring 606 can also be a compression spring. One end of the compression spring is connected to the first rod 701, and the other end is connected to the door body 101. The compression spring is located on the side of the first rod 701 facing the pull handle 602, that is, when the user pulls the handle 602 forward, the compression spring is located in front of the first rod 701. When opening the door, the user pulls the handle 602, and the handle 602 rotates forward relative to the door body 101. The assist rod 603 moves with the handle 602, causing the compression spring to be compressed. That is, the length of the compression spring changes from its original length to its compressed length. The backward thrust of the compression spring on the first rod 701 increases as the rotation angle of the assist rod 603 increases. When the user releases the handle 602, the first rod 701 is subjected to the backward thrust of the compression spring, causing the assist rod 603 to rotate in the opposite direction and achieve reset. Correspondingly, the length of the compression spring changes from its compressed length to its original length, and the compression spring returns to its natural state.

[0083] It should be noted that the compression spring can also be connected to the second rod 702, in which case the compression spring is located behind the second rod 702. When opening the door, the user pulls the handle 602, and the second rod 702 compresses the compression spring backward. When the user releases the handle 602, the second rod 702, due to the forward thrust of the compression spring, causes the assist rod 603 to rotate in the opposite direction and reset.

[0084] Understandably, the first return spring 606 can also be a torsion spring, sleeved on the second pivot 605. One end of the torsion spring is connected to the first rod 701, and the other end is connected to the door body 101. When opening the door, the user pulls the handle 602, which rotates forward relative to the door body 101. The assist rod 603 follows the movement of the handle 602, causing the torsion spring to deform. That is, the assist rod 603 rotates around the center of the torsion spring, generating torque or rotational force. The torsion spring can store and release angular energy or statically fix the assist rod 603 by rotating a lever arm around the central axis of the torsion spring. The end of the torsion spring can be wound into a hook shape or a straight torsion arm. When the user releases the handle 602, the assist rod 603, due to the rotational force of the torsion spring, rotates in the opposite direction and resets, correspondingly restoring the torsion spring to its natural state.

[0085] Reference Figures 6 to 12 As shown, it can be understood that the assist mechanism 601 also includes a fixing block 607, which is fixedly connected to the door body 101. (Refer to...) Figure 11 and Figure 12 As shown, a guide hole 1101 is provided on the fixing block 607. The guide hole 1101 is arranged in a direction perpendicular to the door body 101 and passes through the fixing block 607. The push rod 604 passes through the guide hole 1101 and moves along the axial direction of the guide hole 1101. The guide hole 1101 enables the push rod 604 to move in a predetermined direction, making the movement process more stable and less prone to deviation or shaking.

[0086] Reference Figure 11 and Figure 12 As shown, it can be understood that the fixing block 607 is provided with a clearance notch 1102, which is located on the side of the fixing block 607 near the second rod portion 702. The clearance notch 1102 communicates with the guide hole 1101, and at least a portion of the second rod portion 702 is located in the clearance notch 1102. The fixing block 607 is provided with an upper limit portion 1103 and a lower limit portion 1104, both of which are located at the clearance notch 1102. Specifically, the upper limit portion 1103 is located on the upper side of the clearance notch 1102, and the lower limit portion 1104 is located on the lower side of the clearance notch 1102. The upper limit portion 1103 and the lower limit portion 1104 define the upper and lower boundaries of the clearance notch 1102.

[0087] Reference Figure 7 , Figure 8 and Figure 10 As shown, it can be understood that during the opening and closing of the door, that is, during the rotation of the assist rod 603, the second rod 702 is always located between the upper limit part 1103 and the lower limit part 1104, thereby limiting the vertical direction of the second rod 702 and preventing the second rod 702 from deviating in the vertical direction and affecting the normal operation of the push rod 604.

[0088] Understandably, because the angle between the second rod 702 and the axis of the guide hole 1101 changes continuously during rotation, without a clearance notch 1102, the end of the push rod 604 near the second rod 702 will be suspended in mid-air, causing unstable movement and potential jamming. For example, when opening the door, if the push rod 604 is in the extended position with the end near the second rod 702 inside the guide hole 1101, then when closing the door, the push rod 604 will be in the retracted position, with the end near the second rod 702 extending out of the guide hole 1101. Only during the opening process will this end retract into the guide hole 1101. However, when the push rod 604 is in the retracted state, the end of the push rod 604 near the second rod portion 702 is located inside the guide hole 1101. Because there is no clearance notch 1102, the second rod portion 702 is interfered with by the fixing block 607 and cannot push the push rod 604 out. Therefore, by providing the clearance notch 1102, when the push rod 604 is in the retracted state, the end of the push rod 604 near the second rod portion 702 is located inside the guide hole 1101, allowing the second rod portion 702 to continue rotating and push the push rod 604 out without interfering with the fixing block 607. Thus, by providing the clearance notch 1102 on the fixing block 607, the end of the push rod 604 near the second rod portion 702 is always located inside the guide hole 1101. This supports the push rod 604 and limits its movement, preventing the push rod 604 from jamming due to force deviation.

[0089] It should be noted that the fixing block 607 can be an independent component, connected to the door body 101 via a connector, or the fixing block 607 can be an integral structure with the door body 101, that is, the fixing block 607 is one part of the door body 101.

[0090] Understandably, the assist mechanism 601 also includes a second return spring. One end of the second return spring is connected to the push rod 604, and the other end is connected to the fixing block 607. The second return spring has a deformed state and a natural state. When closing the door, the second return spring is in the natural state. When opening the door, the user pulls the handle 602, and the assist rod 603 moves with the handle 602, which causes the push rod 604 to push out, causing the second return spring to change to the deformed state. When the user releases the handle 602, the push rod 604 returns to its original position under the action of the second return spring, and the second return spring also changes from the deformed state to the natural state.

[0091] Reference Figure 9As shown, it can be understood that the push rod 604 is provided with a mounting boss 903. The mounting boss 903 is located at the end of the push rod 604 near the second rod portion 702, that is, the mounting boss 903 is located at the front end of the push rod 604. The mounting boss 903 is provided with a first mounting portion 904, and one end of the second return spring is mounted on the first mounting portion 904. The first mounting portion 904 is located on the rear side of the mounting boss 903. (Refer to...) Figure 11 and Figure 12 As shown, a mounting groove 1105 is provided on the fixing block 607 at the position corresponding to the mounting boss 903. The mounting groove 1105 accommodates the mounting boss 903 and the first mounting part 904, so that the push rod 604 does not interfere with the fixing block 607 in the direction of back-and-forth movement. A second mounting part 1201 is provided on the side of the mounting groove 1105 away from the mounting boss 903, and one end of the second return spring is mounted on the second mounting part 1201.

[0092] Understandably, the second return spring can be a compression spring, with one end connected to the first mounting part 904 and the other end connected to the second mounting part 1201, and the compression spring located behind the mounting boss 903. When opening the door, the user pulls the handle 602, which rotates forward relative to the door body 101. The assist rod 603 moves with the handle 602, and the push rod 604 pushes backward, reducing the distance between the first mounting part 904 and the second mounting part 1201. The compression spring is compressed, meaning its length changes from its original length to its compressed length. The backward thrust of the compression spring on the push rod 604 increases as the rotation angle of the assist rod 603 increases. When the user releases the handle 602, the push rod 604, due to the forward thrust of the compression spring, moves in the opposite direction and returns to its original length. Correspondingly, the length of the compression spring changes from its compressed length to its original length, and the compression spring returns to its natural state.

[0093] It is understood that in some other embodiments, the second return spring can also be a tension spring. In this case, the mounting boss 903 is located at the rear end of the top rod 604, the first mounting part 904 is located in front of the mounting boss 903, and the second mounting part 1201 is located in front of the first mounting part 904. One end of the tension spring is connected to the first mounting part 904, and the other end is connected to the second mounting part 1201. When opening the door, the user pulls the handle 602, and the handle 602 rotates forward relative to the door body 101. The assist rod 603 moves with the handle 602, and the top rod 604 pushes backward. The distance between the first mounting part 904 and the second mounting part 1201 increases, causing the tension spring to be stretched. That is, the length of the tension spring changes from its original length to its extended length. The forward pulling force of the tension spring on the top rod 604 increases as the rotation angle of the assist rod 603 increases. When the user releases the handle 602, the push rod 604 is pulled forward by the tension spring, causing the push rod 604 to rotate in the opposite direction and reset. Correspondingly, the length of the tension spring changes from the extended length to the original length, and the tension spring returns to its natural state.

[0094] Understandably, to enhance the effort-saving effect of the assist mechanism 601, the length of the first rod 701 can be increased, making the distance L1 from the point of force application of the handle 602 to the central axis of the second rotating shaft 605 longer. The handle 602 is installed at the end of the first rod 701, forming a cantilever structure. The handle 602 has a certain weight, which may cause the assist rod 603 to tilt, resulting in a jamming sensation when rotating the assist rod 603, affecting the user experience. Furthermore, if the assist rod 603 lacks a limiting structure, it may easily rotate beyond its predetermined position, causing spring failure or the handle 602 to strike the door 101 or the box 1801, generating noise.

[0095] Reference Figure 13 and Figure 14As shown, the assist mechanism 601 also includes a retainer 1301, which limits the movement of the handle 602 and the assist rod 603, making the rotation of the assist rod 603 smoother and restricting its rotation within a certain range. The retainer 1301 is provided with an operating groove 1302, in which the handle 602 is located, allowing the user to reach into the operating groove 1302 to grip the handle 602. A limiting groove 1401 is provided on the side of the retainer 1301 away from the top rod 604. The limiting groove 1401 is connected to the operating groove 1302. That is, the limiting groove 1401 is located on the right side wall of the operating groove 1302, and the right side of the handle 602 is located in the limiting groove 1401, so that the handle 602 can slide along the front and back direction of the limiting groove 1401. The limiting groove 1401 limits the vertical direction of the handle 602 to prevent the handle 602 from tilting in the vertical direction due to its own weight or the direction of force applied by the user. A limiting port 1303 is provided on the side of the retainer 1301 near the top rod 604. The limiting port 1303 is connected to the operating groove 1302, that is, the limiting port 1303 is located on the left side wall of the operating groove 1302. The first rod 701 enters the operating groove 1302 after passing through the limiting port 1303. The front and rear side walls of the limiting port 1303 can limit the front and rear directions of the first rod 701, thereby limiting the rotation angle of the assist rod 603 in two directions.

[0096] Reference Figure 6 and Figure 13 As shown, it can be understood that the handle 602 includes an auxiliary part 608, which is located inside the limiting port 1303. The auxiliary part 608 and the first rod part 701 are arranged in the vertical direction, so that they can have a certain limiting effect in the vertical direction, making the assist rod 603 rotate more smoothly.

[0097] The following is combined with Figures 15 to 17 This describes the process of the assist mechanism 601 and the hinge 201 cooperating in an embodiment of the present invention.

[0098] Reference Figure 15 As shown, it can be understood that when the door 101 is in the closed state, the sliding pressure block 306 and the sliding guide block 305 are separated and arranged opposite each other in the front-back direction. At this time, the first rotating shaft 301 is located at the junction of the first sliding section 401 and the second sliding section 402. The top rod 604 is retracted into the fixed block 607, and the first return spring 606 is in the natural state.

[0099] Figure 16The assist mechanism 601 and hinge 201 shown are located on the opening side of the door 101. It can be understood that when the handle 602 is pulled forward by the user, the assist rod 603 is subjected to a force that tends to cause the assist rod 603 to rotate around the second pivot 605. This causes the end of the second rod portion 702 to push the push rod 604 toward the sliding guide block 305. The push rod 604 exerts a rearward force on the sliding guide block 305. Since the sliding guide block 305 remains relatively stationary with the housing 1801, and the second pivot 605 remains relatively stationary with the door 101, the second pivot 605 is subjected to a forward reaction force. This reaction force causes the opening side of the door 101 to move forward. The outer surface of the sliding pressure block 306 slides along the outer surface of the sliding guide block 305, and the first pivot 301 slides toward the opening of the sliding groove 304 and gradually disengages from the moving part 203. As a result, the sealing gasket 1803 on the opening side breaks free from the magnetic force of the magnet and begins to leave the outer casing frame 1802.

[0100] Figure 17 The assist mechanism 601 and hinge 201 shown are located on the rotating side of the door 101. It can be understood that as the door 101 opens on the opening side, the first rotating shaft 301 slides into the tail end of the second sliding section 402. The tail end of the second sliding section 402 rotates and engages with the first rotating shaft 301. The inner side of the first arc-shaped boss 302 matches the arc surface 404 of the revolving door. The outer surface of the sliding pressure block 306 slides along the outer surface of the sliding guide block 305. The assist mechanism 601 remains relatively stationary with the door 101.

[0101] It should be noted that the assist mechanism 601 can also adopt other structural forms. For example, a gear transmission mechanism can be used instead of a lever transmission mechanism in the middle, and the handle 602 can be connected to the drive wheel. The handle 602 drives the drive wheel to rotate, the drive wheel transmits power to the driven wheel, and the driven wheel transmits power to the push rod 604 (with a rack), so that the push rod 604 can be driven to push out toward the housing 1801.

[0102] Reference Figure 2 and Figure 18 As shown, it can be understood that the hinge 201 installed at the lower part of the door body 101 also includes a roller assembly 204. The roller assembly 204 is installed at the bottom of the movable part 203. A guide part 205 is provided on the fixed part 202. The guide part 205 is located at the top of the fixed part 202 and cooperates with the roller assembly 204. The guide part 205 is used to guide the roller assembly 204 to move in the front and back direction.

[0103] Reference Figure 2 and Figure 18As shown, it can be understood that the guide section 205 includes a first inclined section 206, which is located in the rear half of the guide section 205, with the front end of the first inclined section 206 higher than its rear end. When closing the door, the roller assembly 204 slides on the guide section 205 to reduce the motion friction between the fixed member 202 and the moving member 203. When the roller assembly 204 passes the front end of the first inclined section 206, i.e., between the front end and the rear end of the first inclined section 206, and passes the highest point of the first inclined section 206, the door 101 falls back down along the trajectory of the first inclined section 206, achieving gravity self-locking. It then engages with the housing 1801 using the sealing gasket 1803, completing the seal.

[0104] Reference Figure 2 and Figure 18 As shown, it can be understood that the guide section 205 includes a second inclined section 207, which is located in the front half of the guide section 205, with the front end of the second inclined section 207 lower than its rear end. When closing the door, the roller assembly 204 slides on the second inclined section 207, and the door body 101 gradually rises relative to the housing 1801, helping to pass the highest point of the guide section 205 and reducing resistance during the closing process.

[0105] Reference Figure 2 and Figure 18 As shown, it can be understood that the movable part 203 is provided with a recess 208, which is used to accommodate the roller assembly 204, thereby reducing the space occupied by the hinge 201 and making the structure more compact. The roller assembly 204 includes a spindle and a wheel. The spindle is connected to the two side walls of the recess 208, and the wheel is sleeved on the spindle, enabling the wheel to rotate around the axis of the spindle.

[0106] Understandably, the assist mechanism 601 can be located either at the bottom of the door 101 or on its side. The advantage of placing the assist mechanism 601 at the bottom of the door 101 is that it is not visible on the outer surface of the refrigerator, achieving a concealed design and better aesthetic consistency. However, the limited operating space at the bottom of the door 101 restricts the structure of the assist mechanism 601. For example, the handle 602 has virtually no room to rotate downwards; therefore, it is generally designed as an outward-extending structure.

[0107] Taking the structure of handle 602 rotating outward as an example, refer to Figure 19As shown, it is understandable that the door 101 rotates around its right side to open the left side, and the left side requires the hinge 201. Therefore, the assist mechanism 601 needs to be positioned slightly towards the center. Furthermore, to make the assist mechanism 601 require less effort, the push rod 604 should be positioned towards the left, thus increasing the distance to the right pivot. Accordingly, the handle 602 is located on the side of the push rod 604 facing the centerline of the door 101. When opening the door, the handle 602 rotates from right to left (counterclockwise as shown in the diagram), while opening the left side of the door 101 requires rotating the door 101 from left to right (clockwise as shown in the diagram). The different rotation directions cause users to need to switch the direction of force when opening the door, resulting in inconvenience. In related products, to avoid this problem, an aesthetic compromise has been made by placing the assist mechanism 601 on the side of the door 101.

[0108] In this embodiment of the refrigerator, a roller assembly 204 is added to the hinge 201 at the lower part of the door 101, and a guide portion 205 is provided on the fixing member 202. The guide portion 205 includes a second inclined section 207, the front end of which is lower than the rear end of the second inclined section 207. When the door is closed, the roller assembly 204 is located behind the second inclined section 207, that is, the roller assembly 204 is located on the first inclined section 206 or between the first inclined section 206 and the second inclined section 207. When the push rod 604 of the assist mechanism 601 extends, the left door 101 opens a certain distance, meaning the right side of the door 101 is at a predetermined distance from the edge 1802 of the cabinet 1801. The roller assembly 204 moves forward and enters the second inclined section 207, meaning it passes the highest point of the second inclined section 207 and is located between the front and rear ends of the second inclined section 207. Utilizing the inertia of the opening door 101 and its gravity, the roller assembly 204 continues to move along the second inclined section 207, thereby rotating the door 101 and opening it. This eliminates the need for the user to apply force to rotate the door 101 from left to right, making it more convenient to use. In other words, the refrigerator of this embodiment achieves a concealed design, reduces user operation steps, and improves the user experience.

[0109] 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.
