Description

Technical Field

[0001] The invention relates to the technical field of refrigeration equipment manufacturing, and in particular to a two-way door opening refrigeration equipment. Background Art

[0002] The refrigeration equipment currently on the market generally has a one-way door opening method. For example, if a hinge shaft is installed on the right side of the door, the door is opened from the left side. This limits the placement of the refrigeration equipment and causes inconvenience to users. Although some refrigeration equipment has a hinge shaft hole on the left side of the door, this requires after-sales engineers to replace or swap the position of the hinge. In daily life, a family may have different habits. Some are used to opening the door from the left, while others are used to opening the door from the right. With the trend of home appliances becoming more and more intelligent, the existing one-way door opening refrigeration equipment can only meet the door opening habits of some people, which reduces the user experience. It is impossible to intelligently change the door opening method according to user needs and cannot meet the needs of smart homes. Summary of the invention

[0003] The present invention provides a two-way door refrigeration device to solve the above technical problems.

[0004] To achieve one of the above-mentioned purposes of the invention, an embodiment of the present invention provides a two-way door opening refrigeration device, comprising: a box body, a door body and hinge structures arranged at the four corners of the box body and the door body, wherein the door body has a door body and handles arranged on both sides of the door body.

[0005] The hinge structure comprises: a hinge seat, which is arranged on the box body and has a hinge axis;

[0006] A shaft sleeve assembly is arranged on the door body and cooperates with the hinge shaft. The shaft sleeve assembly includes a first clamping member and a second clamping member arranged opposite to each other, a containing space formed between the first clamping member and the second clamping member, a first opening and a second opening arranged between two ends of the first clamping member and the second clamping member, and an elastic mechanism; the hinge shaft can enter or move out of the containing space from the first opening in a radial direction;

[0007] The driving assembly includes: an actuator and a connecting rod mechanism connected between the actuator and the handle; the actuator is arranged in cooperation with the sleeve assembly, and when the handle is pulled outward, the handle drives the actuator to move through the connecting rod mechanism, so that the opening size of the first opening increases and the hinge shaft is unlocked. At this time, the elastic mechanism cooperates with the first clamping member and the second clamping member to maintain the opening size of the first opening after unlocking.

[0008] As a further improvement of the above technology, the connecting rod mechanism is movably connected to the door body through a connecting rod, and the connecting rod mechanism can rotate with the connecting rod as a base point; and when the handle is pulled outward, the connecting rod mechanism rotates with the connecting rod as a base point, thereby driving the actuator to move toward the inside of the accommodating space.

[0009] As a further improvement of the above technology, the connecting rod and the connecting rod structure are movably connected on a side of the connecting rod structure close to the handle.

[0010] As a further improvement of the above technology, the handle is passed through and fixed on the door body, and has an operating part extending along the height direction of the door body and a fixing part extending from the operating part toward the door body; the fixing part is connected from the handle through hole on the door body to the connecting rod structure arranged up and down on the same side of the door body.

[0011] As a further improvement of the above technology, the first clamping member and the second clamping member are both semi-annular structures, the elastic mechanism is arranged at the second opening between the first clamping member and the second clamping member, and the second opening is arranged opposite to the first opening.

[0012] As a further improvement of the above technology, the actuator is arranged in the second opening, the cross-sectional area of ​​one end of the actuator is larger than the cross-sectional area of ​​the other end, and when the handle is pulled outward, the connecting rod mechanism drives the actuator to move inwardly toward the accommodating space in the second opening, so that the cross-sectional area of ​​the part thereof in the second opening gradually decreases, and under the action of the elastic mechanism, the opening size of the first opening gradually increases, so that the hinge shaft can move out of the accommodating space.

[0013] As a further improvement of the above technology, the actuating member extends radially along the shaft sleeve assembly and is always disposed in the second opening.

[0014] As a further improvement of the above technology, the large end of the actuating member is arranged toward the inside of the accommodating space, and a matching surface matching with the hinge shaft is formed at the large end.

[0015] As a further improvement of the above technology, the actuating member is a conical structure radially extending through the second opening along the shaft sleeve assembly.

[0016] As a further improvement of the above technology, the door body is provided with a receiving groove cooperating with the shaft sleeve assembly and a guide hole for the movement of the actuator on the four corners close to the box body, and the guide hole intersects the receiving groove vertically and the guide hole is perpendicular to the contact surface between the door body and the box body.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] In the description of the present invention, it should be noted that if there are descriptions involving "first", "second", etc., the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, it cannot be understood as limiting the present invention.

[0028] like Figures 1 to 4 As shown, an embodiment of the present invention provides a two-way door refrigeration device 100, which includes a box body 200, a door body 300, and hinge structures 400 arranged at four corners of the box body 200 and the door body 300. The door body 300 has a door body 310 and handles 320 arranged on both sides of the door body 310.

[0029] In one embodiment of the present invention, the hinge structure 400 includes a hinge seat 410, a sleeve assembly 420 and a drive assembly 430.

[0030] The hinge seat 410 is disposed on the box body 200 and has a hinge shaft 412 .

[0031] The sleeve assembly 420 is disposed on the door body 310 and is arranged in cooperation with the hinge shaft 412. The sleeve assembly 420 includes a first holding member 421 and a second holding member 422 that are arranged opposite to each other, an accommodation space 423 formed between the first holding member 421 and the second holding member 422, a first opening 424 and a second opening 425 that are arranged between the two ends of the first holding member 421 and the second holding member 422, and an elastic mechanism 426. The hinge shaft 412 can enter or move out of the accommodation space 423 from the first opening 424 in the radial direction.

[0032] The driving assembly 430 includes an actuating member 432 and a connecting rod mechanism 434 connected between the actuating member 432 and the handle 320, wherein the actuating member 432 is arranged in cooperation with the shaft sleeve assembly 420. When the handle 320 is pulled outward, the handle 320 drives the actuating member 432 to move through the connecting rod mechanism 434, so that the opening size of the first opening 424 increases and the hinge shaft 412 is unlocked. At this time, the elastic mechanism 426 cooperates with the first holding member 421 and the second holding member 422 to maintain the opening size of the first opening 424 after unlocking.

[0033] In one embodiment of the present invention, in order to realize the movement of the hinge shaft 412 into or out of the accommodation space 423 and thus complete the opening and closing of the door body 200, the first holding member 421 and the second holding member 422 are both configured as semi-annular structures, and an elastic mechanism 426 is provided at the second opening 425 between the first holding member 421 and the second holding member 422. The second opening 425 is arranged opposite to the first opening 424. Optionally, the elastic mechanism 426 can be configured as a tension spring or other elastic elements.

[0034] In one embodiment of the present invention, the second opening 425 is provided with not only an elastic mechanism 426 but also an actuating member 432. The actuating member 432 is inserted into the second opening 425, and the cross-sectional area of ​​one end of the actuating member 432 is larger than the cross-sectional area of ​​the other end. When the handle 320 is pulled outward, the connecting rod mechanism 434 drives the actuating member 432 to move toward the inner side of the accommodating space 423 in the second opening 425, so that the cross-sectional area of ​​the part in the second opening 425 gradually decreases, and under the action of the elastic mechanism 426, the opening of the first opening 424 gradually increases, so that the hinge shaft 412 can be moved out of the accommodating space 423, thereby completing the opening of the door body 300.

[0035] The actuating member 432 extends radially along the shaft sleeve assembly 420, and the actuating member 432 is always inserted into the second opening 425 during the movement of the actuating member 432 in the second opening 425. During the movement of the actuating member 432, the moving distance of the actuating member 432 in the second opening 425 is substantially the same, and accordingly, the moving distances of the first clamping member 421 and the second clamping member 422 under the action of the elastic mechanism 426 are also constant, thereby ensuring that the opening direction of the first opening 424 is always facing the hinge shaft 412.

[0036] In one embodiment of the present invention, the large end of the actuating member 432 is disposed toward the inner side of the accommodating space 423, and a matching surface 4322 matching with the hinge shaft 412 is formed at the large end. Figure 5 As shown, the mating surface 4322 is a smooth curved surface that matches the outer peripheral surface of the hinge shaft 412. When the actuator 432 rotates around the hinge shaft 412, the mating surface is always tightly fitted with the outer side surface of the hinge shaft 412, thereby preventing the door body 300 from being separated from the box body 200 and improving user satisfaction.

[0037] In the process of opening or closing the door body 300, the working process needs to be smooth, and the corresponding actuating member 432 needs to move smoothly in the second opening 425, and at the same time, the cross-sectional area of ​​one end must be greater than the cross-sectional area of ​​the other end. Therefore, the actuating member 432 can be set as a conical structure radially penetrating the second opening 425 along the shaft sleeve assembly 420. Of course, the actuating member 432 also has other implementations, which will not be described one by one.

[0038] In one embodiment of the present invention, the end of the actuating member 432 with a smaller cross-sectional area is movably connected to the connecting rod mechanism 434. The connecting rod mechanism 434 is disposed between the actuating member 432 and the handle 320, and the movement of the handle 320 drives the actuating member 432 to move forward and backward relative to the accommodating space 423. The connecting rod mechanism is disposed on both left and right sides of the door body 300.

[0039] Reference Figure 6 and Figure 7 In one embodiment of the present invention, the door body 300 further includes accommodating cavities 330 disposed on both sides of the door body 310 in the width direction. The accommodating cavities 330 extend along the height direction of the door body 300, and the opening is disposed toward a side away from the box body 200, for accommodating the connecting rod mechanism 434.

[0040] The link mechanism 434 is movably connected to the door body 310 via a connecting rod 436. Specifically, the link mechanism 434 and the connecting rod 436 are disposed in the accommodating cavity 330. The link mechanism 434 can rotate with the connecting rod 436 as a base point, and when the handle 320 is pulled outward, the link mechanism 434 rotates with the connecting rod 436 as a base point, thereby driving the actuating member 432 to move toward the inside of the accommodating space 423.

[0041] In one embodiment of the present invention, the space in which the handle 320 can move relative to the door body 300 is small, and therefore the connecting rod 436 is arranged in the accommodating cavity 330 near the handle 320. Accordingly, the connecting rod 436 and the connecting rod mechanism 434 are movably connected on the side of the connecting rod mechanism 434 near the handle 320. Optionally, the movable connection point between the connecting rod 436 and the connecting rod mechanism 434 can be set at 1 / 4 of one end of the connecting rod mechanism 434 near the handle 320.

[0042] Reference Figure 8 , one end of the connecting rod 436 is connected to the door body 310, and the other end of the connecting rod 436 is hinged to the connecting rod mechanism 434. The connecting rod mechanism 434 is provided with a hole 4342, and the connecting rod 436 is passed through the hole 4342 of the connecting rod mechanism 434. In one embodiment of the present invention, one end of the connecting rod 436 is connected to the door body 310, and the other end of the connecting rod 436 is provided with an external thread, and the connecting rod 436 passes through the hole 4342 on the connecting rod mechanism 434, and is positioned by nuts on both sides of the hole 4342 to ensure that the connecting rod mechanism 434 will not slip off the connecting rod 436 during the rotation process.

[0043] In other embodiments of the present invention, the connecting rod 436 can be fixed at both ends on the left and right side walls of the accommodating cavity 330, and the connecting rod 436 passes through the hole 4342 to enable the connecting rod mechanism 434 to rotate around the connecting rod 436. Similarly, the connection form between the connecting rod mechanism 434 and the connecting rod 436 can also be other forms, which can ensure that the connecting mechanism 434 can rotate around the connecting rod 436.

[0044] In one embodiment of the present invention, the door body 300 further includes a cover plate 360 ​​for covering the front opening of the accommodating cavity 330. The cover plate 360 ​​can be arranged at the front opening of the accommodating cavity 330 by welding or snap-fitting structure. The cover plate 360 ​​is provided with a handle through hole 362 in a direction perpendicular to the door body 310, and the handle 320 passes through the cover plate 360 ​​and is movably connected to the connecting rod mechanism 434.

[0045] In one embodiment of the present invention, there are four groups of the shaft sleeve assembly 420, which are arranged at the upper top and lower bottom of the left and right sides of the door body 300. Correspondingly, there are also four groups of driving assemblies 430 matching the shaft sleeve assembly 420. Therefore, in order to facilitate the door body 300 to be able to be opened and closed from the left or right side, the connecting rod mechanisms 434 in the two driving assemblies 430 on the same side are connected to the handle 320 on the same side. Specifically, the two groups of connecting rod mechanisms 434 on the left side of the door body 300 are connected to the handle 320 on the left side of the door body 300, and the two groups of connecting rod mechanisms 434 on the right side of the door body 300 are connected to the handle 320 on the right side of the door body 300.

[0046] In one embodiment of the present invention, the handle 320 is fixed on the door body 300, and has an operating portion 322 extending in the height direction of the door body 300 and a fixing portion 324 extending from the operating portion 322 toward the door body 300. The fixing portion 324 is connected to the link mechanism 434 arranged on the same side of the door body 300 from the handle through hole 362 on the door body 300. In one embodiment of the present invention, the handle through hole 362 is arranged on the cover plate 360, and the handle can be set as a U-shaped handle.

[0047] In one embodiment of the present invention, the door body 300 further includes a receiving groove 340 located at a corner of the door body 310 and matched with the shaft sleeve assembly 420. The receiving groove 340 is connected with the receiving cavity 330 along the front-to-back direction to accommodate the shaft sleeve assembly 420. Specifically, the receiving groove 340 is arranged at the four corners of the door body 310 close to the box body 200, and the receiving groove 340 is connected with the receiving cavity 330 through a guide hole 350 for the movement of the actuator 432, and the guide hole 350 intersects the receiving groove 340 vertically and the guide hole 350 is perpendicular to the contact surface between the door body 300 and the box body 200. Optionally, the receiving groove 340 can be set as a semi-annular slide groove that matches the first clamping member 421 and the second clamping member 422.

[0048] During the use of the two-way door refrigeration device 100, when the user of the two-way door refrigeration device 100 opens the door from the left side, the door body 300 rotates around the axis of the hinge shaft 412 in the hinge structure 400 installed on the right side of the box body 200. At this time, the user pulls the handle 320 outward, driving the connecting rod structure 434 to rotate with the connecting rod 436 as the base point, and then drives the actuator 432 to move toward the inside of the accommodating space 423. At this time, the cross-sectional area of ​​the actuator 432 in the second opening 425 gradually decreases, and under the action of the elastic mechanism 426, the opening width of the first opening 424 between the first clamping member 421 and the second clamping member 422 gradually increases until the hinge shaft 412 can be completely moved out of the first opening 424.

[0049] When the user closes the door, under the action of the elastic mechanism 426, the opening width of the first opening 424 can pass through the hinge shaft 412, and the hinge shaft 412 moves from the outside of the accommodating space 423 to the inside, and then contacts the matching surface 4322 of the actuating member, and the hinge shaft 412 continues to push the actuating member 432 to move from the inside of the accommodating space 423 to the outside. At this time, the cross-sectional area of ​​the actuating member 432 in the second opening 425 becomes larger and larger, and then the width of the first opening 424 becomes smaller and smaller, completing the locking of the hinge shaft 412 and realizing the closing of the door body 300. In the process of the hinge shaft 412 moving from the inside of the accommodating space 423 to the outside, the handle 320 and the connecting rod mechanism 430 gradually return to the state before the door is opened.

[0050] When the refrigeration device 100 opens the door from the left side, the actuator 432 in the hinge structure 400 installed on the right side of the door body is always in close contact with the outer peripheral surface of the hinge shaft 412 with a smooth matching surface 4322, and rotates around the hinge shaft 412 to prevent the door body 300 and the box body 200 from falling off during the opening or closing process of the door body 300.

[0051] Similarly, when the user opens or closes the door from the right side, the actuation process of each part in the two-way door refrigeration device is similar to the process of opening or closing the door from the left side, and will not be described in detail here.

[0052] In summary, the beneficial effects of the present invention are as follows: the two-way door opening refrigeration equipment provided by the present invention can realize rapid switching of the door opening direction to satisfy simultaneous use by users with different usage habits; at the same time, the hinge structure of the present invention realizes the entry or removal of the hinge axis through the opening and closing of the first opening between the first clamping member and the second clamping member, thereby completing the opening or closing of the door body. The hinge structure is a purely mechanical structure with small implementation limitations, low implementation cost, and relatively high feasibility. In the two-way door opening refrigeration equipment provided by the present invention, the connection point between the connecting rod and the connecting rod mechanism is close to the side of the handle, which makes the user's opening / closing process more labor-saving and provides a better user experience.

[0053] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0054] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the present invention. They are not intended to limit the scope of protection of the present invention. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the present invention should be included in the scope of protection of the present invention.
