Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a refrigerator door opening structure, and more particularly to a refrigerator door structure that can be opened in both directions. Background Technology

[0002] Refrigerators, as containers that keep food or other items at a constant low temperature, have become an indispensable household appliance in modern homes. A refrigerator typically includes a separate upper and lower refrigerator compartment and a freezer compartment for storing items requiring different temperatures, with two doors for each compartment. Most refrigerators on the market currently have right-opening doors, meaning the hinges are installed on the right side of the door, allowing it to open from the left side. However, with increasing demands for personalization and comfort in refrigerator use, and influenced by home layouts and furniture arrangement, users also have certain requirements regarding the refrigerator's placement and door orientation. Especially when these requirements necessitate a left-opening door, a professional is needed to remove the hinges and reposition them to the other side of the refrigerator, allowing the door to open from the opposite side. This method of reversing the door opening direction is inconvenient, expensive, and requires further professional intervention whenever the refrigerator's location needs to be changed, making it quite troublesome. Especially for motorhomes, there is no availability for professional personnel to come and replace the hinges, and they also require more space. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to solve the technical problem that the refrigerator door cannot be opened in both directions in the prior art, this utility model provides a refrigerator door structure that can be opened in both directions through a switch assembly. The structure is simple and the operation is convenient.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a two-way opening refrigerator door structure, including a door body connected to the refrigerator body, second hinge seats symmetrically arranged on the left and right sides of the refrigerator body, and a second rotating shaft located on the door body and movable relative to the door body at the other end of the second hinge seat. Switch assemblies corresponding to the second rotating shaft are symmetrically arranged on the door body. The switch assembly includes: a latch corresponding to the second rotating shaft, the latch sliding along the x-direction inside the door body; a push-button switch, the push-button switch being disposed on the door body and movable along the z-direction; a connecting rod, the connecting rod being rotatably connected to the door body, with one end abutting against the push-button switch and the other end abutting against the latch; the push-button switch moving along the z-direction and the connecting rod rotating to push the latch to translate, so that the latch abuts against or separates from the second rotating shaft to lock or unlock the second rotating shaft; the door body rotating around the locked second rotating shaft, so that the unlocked second rotating shaft disengages from the door body to open the door body.

[0005] This utility model features a bidirectional refrigerator door structure that allows for switching of the opening direction via a switch assembly. Simply pressing the button switch unlocks the corresponding second pivot, and pulling the door allows the refrigerator door to open from one side. Switching the opening direction is simple and convenient.

[0006] Furthermore, in order to achieve linkage between the push-button switch and the bolt, the connecting rod includes a vertical section and a horizontal section. The vertical section enters the bolt and abuts against the bolt, and the end of the horizontal section abuts against the push-button switch. The push-button switch presses down on the horizontal section, causing the vertical section to rotate synchronously to push the bolt to move.

[0007] Furthermore, in order to enable the push-button switch to automatically reset, the door body has a cavity, the push-button switch is disposed in the cavity, and the push-button switch and the door body are connected by a reset spring.

[0008] Furthermore, in order to ensure that the connecting rod is always in contact with the push button switch, the push button switch includes a pressing part for pushing the horizontal section, the bottom surface of the pressing part pressing down on the horizontal section until the horizontal section disengages from the bottom surface of the pressing part and abuts against the side surface of the pressing part.

[0009] Furthermore, in order to achieve automatic reset of the latch, the end of the latch has a cavity, the vertical section extends into the cavity to push the latch to move horizontally, and the rear end of the latch is connected to the door body by a reset spring.

[0010] Furthermore, in order to ensure the running trajectory of the latch, a guide is connected to the door body, and the latch has a guide groove. The guide passes through the guide groove, causing the latch to move in the x-direction.

[0011] Furthermore, in order to ensure that the second pivot can be smoothly locked by the latch when the door is closed, the front end of the latch also has an arc-shaped guide surface, and the second pivot pushes the arc-shaped guide surface to retract the latch.

[0012] Furthermore, in order to lock the switch assembly, a locking component is also movably provided on the door body. The locking component contacts or separates from the switch assembly to lock or unlock the switch assembly.

[0013] Furthermore, in order to achieve a separate locking switch assembly, the locking component is a third switch, which is movably disposed within the door body and can be translated along the y-direction. The third switch abuts against or separates from the latch to lock or unlock the switch assembly.

[0014] Furthermore, in order to limit the locking tongue, the end face of the third switch facing the locking tongue has a boss, and the locking tongue has a rib corresponding to the boss. The boss and the rib abut against each other to limit the translation of the locking tongue.

[0015] Furthermore, in order to ensure the position of the third switch, a limiting post is provided inside the third switch, and at least two limiting parts are provided on the door body at intervals. The upper end of the limiting post is connected to the switch by a spring, and the sliding of the third switch causes the limiting post to selectively abut against either limiting part.

[0016] Furthermore, in order to achieve that the two switch components are in different states, the locking component is a second slide bar. The second slide bar is movably installed inside the door body and can be translated along the x-direction. The second slide bar is located between two push-button switches. One end of the second slide bar abuts against one push-button switch to lock the push-button switch, and the other end separates from the other push-button switch to unlock the push-button switch.

[0017] Furthermore, in order to limit the button switch, the button switch has a locking groove, and the end of the second slider enters the locking groove to lock the button switch.

[0018] Furthermore, in order to realize the translation of the second slide bar, the door body is also provided with a second knob. The second knob has a protrusion, and the second slide bar has a second groove. The protrusion extends into the second groove. The rotation of the second knob causes the protrusion to push the second slide bar to translate.

[0019] Furthermore, in order to ensure the rotation position of the second knob, a second knob limiting post is provided inside the second knob. The upper end of the second knob limiting post is connected to the second knob through a second knob spring. Multiple limiting grooves that cooperate with the second knob limiting post are evenly distributed along the circumference inside the door body.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. The refrigerator door structure of this utility model with bidirectional opening locks the corresponding second pivot through the switch components on both sides. When the button switch is pressed, the corresponding second pivot is unlocked by the locking tongue, thereby adjusting the opening direction of the refrigerator door. The door can be opened by simply pulling the door body.

[0022] 2. The refrigerator door structure of this utility model with bidirectional opening uses a locking switch to lock or unlock the switch assembly, so as to prevent the switch assemblies on both sides from opening at the same time. Attached Figure Description

[0038] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0039] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0040] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] Example 1, as Figures 1 to 2 As shown, a two-way opening refrigerator door structure includes a door body 1 connected to the refrigerator body. In this embodiment, the freezer door at the top of the refrigerator is used for illustration. Second hinge seats 21 are symmetrically provided on the left and right sides of the refrigerator body. The other end of each second hinge seat 21 is provided with a second pivot 22 located on the door body and movable relative to the door body 1. The second hinge seats 21 are located at the lower end face of the door body 1.

[0042] Specifically, the door body 1 is symmetrically equipped with switch assemblies corresponding to the second pivot 22. The switch assemblies include a latch 23, a push-button switch 24, and a linkage 25 corresponding to the second pivot 22.

[0043] Specifically, the latch 23 slides along the x-axis inside the door body 1. The push-button switch 24 is mounted on the door body 1 and can move along the z-axis. The connecting rod 25 is rotatably connected to the door body 1, with one end abutting against the push-button switch 24 and the other end abutting against the latch 23.

[0044] Specifically, the push-button switch 24 moves along the z-axis and the connecting rod 25 rotates to push the latch 23 to translate, causing the latch 23 to abut or separate from the second pivot 22 to lock or unlock the second pivot 22. The door body 1 rotates around the locked second pivot 22, causing the unlocked second pivot 22 to disengage from the door body 1 to open the door body 1.

[0045] Preferably, the door 1 has a second y-direction groove 26. In the locked state, the second pivot 22 is located at the end of the second y-direction groove 26 away from the refrigerator body and is in close contact with the end face of the latch 23, thereby locking the second pivot 22. When the button switch 24 pulls the latch to unlock, the latch 23 separates from the second pivot 22, and when the door 1 is opened, the second pivot 22 will disengage from the second y-direction groove 26.

[0046] Preferably, the locking tongue 23 is disposed within the second x-groove 27. When the front end of the locking tongue 23 extends into the second y-groove 26, the end face of the locking tongue 23 abuts against the second rotating shaft 22, which is in a locked state. When the locking tongue 23 retracts along the second x-groove 27, the front end of the locking tongue 23 exits the second y-groove 26, and the second rotating shaft 22 is unlocked. When switching on or off, the second rotating shaft 22 disengages from the second y-groove 26.

[0047] To open the refrigerator door from the right, simply press the right-side button switch 24. The button switch 24 moves downwards, pushing the connecting rod 25 to rotate. Simultaneously, the connecting rod 25 moves the latch 23 inwards along the x-axis. At this point, the latch 23 disengages from the inner second pivot 22, unlocking it. Then, simply pull the door body 1 to open the door. The unlocked second pivot 22 will detach from the door body 1, allowing the refrigerator door to open from the right. The same procedure applies to opening from the left. The button switch 24 allows for quick and easy opening of the refrigerator door.

[0048] Preferably, the connecting rod 25 includes a vertical section 251 and a horizontal section 252. The vertical section 251 enters and abuts against the latch 23, and the end of the horizontal section 252 abuts against the push-button switch 24. The push-button switch 24 presses down on the horizontal section 252, causing the vertical section 251 to rotate synchronously to move the latch 23. The push-button switch 24 includes a pressing part for pushing the horizontal section 252. The bottom surface of the pressing part presses down on the horizontal section 252 until the horizontal section 252 disengages from the bottom surface of the pressing part and abuts against the side surface of the pressing part. The end of the latch 23 has a cavity, and the vertical section 251 extends into the cavity to push the latch 23 to translate.

[0049] When the push-button switch 24 is pressed down, the end of the horizontal section 252 is pressed down by the squeezing part. At this time, the horizontal section 252 begins to rotate. As the squeezing part continues to descend, the horizontal section 252 separates from the bottom surface of the squeezing part and abuts against the side surface of the squeezing part. Since the vertical section 251 and the horizontal section 252 rotate synchronously, the vertical section 251 abuts against the side wall of the cavity. During the rotation of the vertical section 251, it pushes the locking tongue 23 to move inward until the push-button switch 24 descends to its limit position. At the same time, the locking tongue 23 also moves to its limit position, and the second rotating shaft 22 is unlocked, at which point the refrigerator door can be opened.

[0050] Preferably, the door body 1 has a cavity inside, and the push-button switch is located inside the cavity. The push-button switch 24 and the door body 1 are connected by a return spring. In order to better accommodate the user pressing the push-button switch 24 to open the refrigerator door at the same time, the user's hand can just grasp the refrigerator door when the push-button switch is pressed, integrating unlocking and opening into a single action, making the door opening action simpler and smoother, and optimizing the user experience.

[0051] Preferably, a guide member 28 is connected to the door body 1, and a guide groove 231 is provided on the latch 23. The guide member 28 passes through the guide groove 231, allowing the latch 23 to move along the x-direction. Through the cooperation of the guide member 28 and the guide groove 231, the latch 23 can always move smoothly along the x-direction, avoiding the latch 23 from deviating and causing it to be unable to open and close smoothly.

[0052] Preferably, the rear end of the latch 23 is connected to the door body 1 via a return spring. The front end of the latch 23 also has an arc-shaped guide surface 232, and the second pivot 22 pushes the arc-shaped guide surface 232 to retract the latch 23. Since the user often releases the button switch 24 after opening the refrigerator door, the button switch 24 and the latch 23 return to the pivot-locked position under the action of the return spring. In order not to affect the closing of the refrigerator door, the front end of the latch 23 is provided with an arc-shaped guide surface 232. When closing the door, the latch 23 moves towards the second pivot 22 until the arc-shaped guide surface 232 contacts the second pivot 22. At this time, the second pivot 22 will push the arc-shaped guide surface 232 to retract, and the latch 23 will automatically give way in the closed state. The latch 23 retracts until the refrigerator door is closed. At this time, the second pivot 22 has moved to the rear end of the latch 23 and separated from the arc-shaped guide surface 232. At this time, the lock is reset under the action of the return spring, locking the second pivot 22 again, completing the closing of the door.

[0053] Example 2, based on Example 1, such as Figures 8 to 10 As shown, the upper surface of the refrigerator body is symmetrically provided with first hinge seats 11 on the left and right sides, and the other end of the first hinge seat 11 is provided with a first pivot 12 located inside the door body 1 and movable relative to the door body 1.

[0054] Specifically, the door body 1 is symmetrically equipped with independent first switches 13, which can slide along the x-axis relative to the first rotating shaft 12. The first switch 13 abuts against the first rotating shaft 12 to lock the first rotating shaft 12, and the first switch 13 separates from the first rotating shaft 12 to unlock the first rotating shaft 12. Corresponding to the first rotating shaft 12, the first switches 13 are also symmetrically arranged on the door body 1.

[0055] The door body 1 is provided with a first x-groove 14 and a first y-groove 15. The first x-groove 14 is located on the side away from the refrigerator body. The first switch 13 slides within the first x-groove 14, causing a portion of the first switch 13 to enter or disengage from the first y-groove 15. When the first switch 13 enters the first y-groove 15, it locks the first rotating shaft 12; when the first switch 13 disengages from the first y-groove 15, it unlocks the first rotating shaft 12. When the first switch 13 slides within the first x-groove 14, it primarily limits the first rotating shaft 12 through its outer portion. When the outer portion of the first switch 13 enters the first y-groove 15, the first rotating shaft 12 is surrounded by the first y-groove 15 and the first switch 13, at which point the first rotating shaft 12 does not have the freedom to move along the first y-groove 15.

[0056] Specifically, according to the desired opening direction, slide the first switch 13 on one side to separate it from the first pivot 12, thus unlocking the first pivot 12 and locking the first pivot 12 on the other side. At this time, the door 1 rotates around the locked first pivot 12, causing the unlocked first pivot 12 to disengage from the door 1, thereby opening the door 1. To adjust the opening direction, simply switch the state of the first switch 13.

[0057] When it is necessary to open the door in the manner described in Embodiment 1, simply use the first switch 13 above the refrigerator door to unlock the corresponding first pivot 12 to open the door.

[0058] In Example 3, based on Example 2, a locking component is also movably provided on the door body 1. The locking component contacts or separates from the switch assembly to lock or unlock the switch assembly.

[0059] like Figures 3 to 5 As shown, specifically, the locking component is the third switch 29, which is movably disposed within the door body 1 and can be moved along the y-direction. The third switch 29 abuts against or separates from the latch 23 to lock or unlock the switch assembly. The second movable switch is disposed within the third y-direction groove 30, and the third switch 29 is located between the refrigerator body and the latch 23. By limiting the latch 23 with the third switch 29, the push-button switch 24 cannot be pressed in this state, thus locking the refrigerator door. When it is necessary to open the refrigerator door, the third switch 29 must first be activated to separate the third switch 29 from the latch 23.

[0060] Specifically, the end face of the third switch 29 facing the latch 23 has a boss 291, and the latch 23 has a corresponding rib 233. The boss 291 and the rib 233 abut against each other to restrict the translation of the latch 23. Because the boss 291 and the rib 233 are engaged, the button switch 24 cannot be pressed when the latch 23 is blocked. When the third switch 29 retracts and the boss 291 and the rib 233 separate, the latch 23 can move normally.

[0061] Specifically, the third switch 29 has a limiting post, and the door body 1 has at least two limiting parts spaced apart. The upper end of the limiting post is connected to the switch via a spring. The sliding of the third switch 29 allows the limiting post to selectively abut against either limiting part. Through the cooperation of the limiting post and the limiting parts, the third switch 29 is limited, preventing the third switch 29 from locking the latch 23 when the door is open, thus preventing the door from closing.

[0062] Example 4, based on Example 1, such as Figures 6 to 7 As shown, the locking component is a second slide bar 31, which is movably disposed within the door body 1 and can be translated along the x-axis. The second slide bar 31 is located between two push-button switches 24. One end of the second slide bar 31 abuts against one push-button switch 24 to lock it, and the other end separates from the other push-button switch 24 to unlock it. When it is necessary to open the door from the right side, slide the second slide bar 31, and the second slide bar 31 engages with the push-button switch 24 on the left side, locking the push-button switch 24 and unlocking the push-button switch 24 on the right side. At this time, press the push-button switch 24 on the right side to open the door as described in Embodiment 1. The same applies to opening the door from the left side; simply lock the push-button switch 24 on the right side with the second slide bar 31.

[0063] Preferably, the push-button switch 24 has a locking groove 241, and the end of the second slider 31 enters the locking groove 241 to lock the push-button switch 24. By cooperating with the slider and the locking groove 241, the push-button switch 24 can be quickly locked or unlocked, simplifying the structure and making operation more convenient.

[0064] Specifically, the door body 1 is also provided with a second knob 33. The second knob 33 has a protrusion, and the second slide bar 31 has a second groove. The protrusion extends into the second groove. Rotating the second knob 33 causes the protrusion to push the second slide bar 31 to move horizontally. By using the cooperation of the protrusion and the second groove, the second knob 33 can drive the second slide bar 31 to move horizontally, simplifying the structure.

[0065] Preferably, the second knob 33 has a knob limiting post inside, and the upper end of the knob limiting post is connected to the second knob 33 through a knob spring. Multiple limiting grooves that mate with the knob limiting post are evenly distributed circumferentially inside the door body 1. The second knob 33 can quickly move the second slide bar 31, and the limiting grooves, knob limiting post, and knob spring work together to limit the rotation angle of the second knob 33, improving control accuracy.

[0066] Since the second knob 33 and the first knob 19 have the same structure and the same connection relationship with the door 1, it can be ensured that the first slide bar 17 and the second slide bar 31 can move synchronously. When opening the refrigerator door, you only need to turn the second knob 33 or the first knob 19 to unlock the corresponding first and second pivots simultaneously. You can open the door by simply pressing the button switch.

[0067] In Embodiment 5, based on Embodiment 4, the upper surface of the refrigerator body is provided with symmetrical first hinge seats 11 on the left and right sides, and the other end of the first hinge seat 11 is provided with a first rotating shaft 12 located inside the door body 1 and movable relative to the door body 1.

[0068] Specifically, a first slide bar 17 is movably installed inside the door body 1, capable of reciprocating. One end of the first slide bar 17 abuts against a first pivot 12 to lock the first pivot 12, while the other end separates from another first pivot 12 to unlock it. Rotating the door body 1 around the locked first pivot 12 disengages the unlocked first pivot 12 from the door body 1, thus opening the door body 1. If it is necessary to open the refrigerator door from the right, simply move the first slide bar 17 to the left, locking the first pivot 12 on the left. At this time, the first slide bar 17 separates from the first pivot 12 on the right, allowing the refrigerator door 1 to rotate around the left pivot, thus opening the refrigerator door from the right. Sliding the first slide bar 17 to the right also allows the refrigerator door to be opened from the left.

[0069] Specifically, the door body 1 is provided with a first sliding groove and a first y-direction groove 15. The first sliding bar 17 slides within the first sliding groove, allowing its end to enter or disengage from the first y-direction groove 15 to lock or unlock the first pivot 12. The first sliding groove 17 is arranged along the x-direction, and both ends of the first sliding bar 17 are beveled. When the first sliding bar 17 disengages from the first y-direction groove 15, its end face is flush with the inner end face of the first y-direction groove 15. This prevents interference between the first pivot 12 and the first sliding bar 17 on the opening side.

[0070] Specifically, a first knob 19 is rotatably mounted on the first slide rail groove. The first knob 19 has a protrusion 191, and the first slide rail 17 has a groove 171. The protrusion 191 extends into the groove 171. Rotating the first knob 19 causes the protrusion 191 to push the first slide rail 17 to move horizontally. By simply rotating the first knob 19, the protrusion 191 rotates synchronously with the first knob 19 and pushes the side wall of the groove 171 to move the first slide rail 17 horizontally. The position of the first slide rail 17 can be quickly adjusted by the first knob 19, realizing quick switching between left and right door opening.

[0071] Preferably, the first knob 19 has two knob limiting posts 192. The upper ends of the knob limiting posts 192 are connected to the first knob 19 via knob springs 193. Multiple limiting grooves 18, which mate with the knob limiting posts 192, are evenly distributed circumferentially within the first slide groove. The knob limiting posts 192 and the limiting grooves 18 can limit the first knob 19, preventing it from becoming loose. Because the limiting grooves 18 are evenly distributed, the rotation angle of the first knob 19 can be precisely limited.

[0072] Preferably, the first knob 19 and the second knob 33 are connected by a synchronizing rod 32, which can ensure that the first knob and the second knob 33 rotate synchronously, realize the synchronous unlocking and locking of the upper and lower ends of the door, simplify the operation steps, and avoid the first pivot 12 and the second pivot 22 on the same side not being unlocked or locked synchronously.

[0073] In summary, the bidirectional opening refrigerator door structure of this utility model achieves the switching of the opening direction through a switch assembly. Simply press the button switch to unlock the corresponding second pivot, and directly pull the door to open the refrigerator door on one side. Switching the opening direction is simple and convenient to operate.

[0074] The above description is based on the preferred embodiments of this utility model. Through the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined by the scope of the claims.
