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

[0008] As a further improvement of the above, the actuating assembly is cooperated with the sleeve assembly and is arranged on the door body; when the hinge shaft moves from the accommodating space to the outside of the first opening, the opening of the first opening gradually increases, and when the hinge shaft moves from the first opening to the inside of the accommodating space, the opening of the first opening gradually decreases.

[0009] As a further improvement of the above, the first fixed shaft and the second fixed shaft are respectively arranged in the middle of the first clamping member and the second clamping member.

[0010] As a further improvement of the above, the first holding member and the second holding member are both semi-annular structures, and first elastic members are respectively provided on the outer sides of the first holding member and the second holding member to connect with the door body.

[0011] As a further improvement of the above, the actuating assembly includes a linkage member arranged at the second opening, the cross-sectional area of ​​one end of the linkage member is larger than the cross-sectional area of ​​the other end, and when the hinge shaft moves from the accommodating space to the outside of the first opening, the linkage member moves in the second opening and the cross-sectional area of ​​the part in the second opening gradually decreases, and under the action of the first elastic member, the opening size of the second opening gradually becomes smaller.

[0012] As a further improvement of the above, the linkage member extends radially along the shaft sleeve assembly and is always inserted into the second opening.

[0013] As a further improvement of the above, the linkage member is a conical structure radially extending through the second opening along the shaft sleeve assembly.

[0015] As a further improvement of the above, the actuating assembly further comprises an actuating member disposed at one end of the linkage member, and when the hinge shaft moves from the accommodating space to the outside of the first opening, the actuating member drives the linkage member to move toward the inside of the accommodating space.

[0016] As a further improvement of the above, the actuating member is a second elastic member connected to an end of the linkage member away from the hinge axis.

[0017] As a further improvement of the above, the four corners of the door body facing the box body are provided with receiving grooves matching the sleeve assembly and guide holes for movement of the actuating assembly, the guide holes intersect with the receiving grooves and are perpendicular to the contact surface between the door body and the box body.

[0026] Reference Figures 1 to 3As shown, in one embodiment of the present invention, a two-way door refrigeration device 100 is provided, and the two-way door refrigeration device 100 includes a box body 120, a door body 140, and hinge structures 200 arranged at four corners of the box body 120 and the door body 140. The hinge structure 200 has a hinge seat 220, a shaft sleeve assembly 240, and an actuating assembly 260.

[0027] In this embodiment, the hinge seat 220 is disposed on the box body 120, and the hinge seat 220 has a support plate 221 and a hinge shaft 223 disposed at one end of the support plate 221. One end of the support plate 221 is fixed to the box body 120 by welding, and the other end of the support plate 221 is provided with a hinge shaft 223. Similarly, in other embodiments of the present invention, the support plate 221 can also be fixed to the door body 140 by other connection methods such as bolt connection.

[0028] In one embodiment of the present invention, the sleeve assembly 240 is disposed on the door body 140 and is arranged in cooperation with the hinge shaft 223. The sleeve assembly 240 includes a first clamping member 241 and a second clamping member 242 that are arranged opposite to each other, a first fixed shaft 243 that passes through the first clamping member 241, and a second fixed shaft 244 that passes through the second clamping member 242. The first clamping member 241 and the second clamping member 242 are movably connected to the door body 140 through the first fixed shaft 243 and the second fixed shaft 244, respectively, and the axial direction of the first fixed shaft 243 and the second fixed shaft 244 is the same as that of the hinge shaft 223.

[0029] Furthermore, a first opening 245 and a second opening 246 are provided between the two ends of the first clamping member 241 and the second clamping member 242 , and the hinge shaft 223 can enter or move out of the accommodating space 247 formed in the first clamping member 241 and the second clamping member 242 from the first opening 245 in the radial direction.

[0030] Reference Figure 4 As shown, the door body 140 is also provided with a receiving groove 142 that matches the shaft sleeve assembly 240. The receiving groove 142 is provided at the four corners of the door body 140 facing the box body 120, and the receiving groove 142 is provided corresponding to the hinge shaft 223. The receiving groove 142 is recessed inward from the upper end surface or the lower end surface of the door body 140, and passes through the side surface of the door body 140 facing the box body 120. Optionally, the receiving groove 142 can be provided as a square or semicircular structure.

[0031] The first fixing shaft 243 and the second fixing shaft 244 are disposed in the receiving groove 142. Correspondingly, a first fixing hole 2411 is disposed in the middle of the first holding member 241, and a second fixing hole 2421 is disposed in the middle of the second holding member 242, so that the first fixing shaft 243 and the second fixing shaft 244 are disposed in the middle of the first holding member 241 and the second holding member 242, respectively. In this embodiment, the first holding member 241 can rotate around the first fixing shaft 243, and the second holding member 242 can rotate around the second fixing shaft 244, so as to change the opening size of the first opening 245.

[0032] In one embodiment of the present invention, in order to make the hinge shaft 223 move in or out of the accommodating space 247 more smoothly, the first clamping member 241 and the second clamping member 242 are both configured as semi-annular structures, and the first clamping member 241 and the second clamping member 242 are respectively provided with first elastic members 248 on the outer sides thereof to connect with the door body 140. The first elastic member 248 may be a tension spring, a rubber spring or other elastic elements.

[0033] Furthermore, side plates 143 protruding from the door body 140 toward the box body 120 are provided on both sides of the accommodating groove 142 , and the first elastic member 248 is connected to the door body 140 via the side plates 143 .

[0034] In one embodiment of the present invention, the first elastic member 248 can cooperate with the actuating assembly 260 to change the size of the first opening 245. The actuating assembly 260 is arranged on the door body 140 in cooperation with the shaft sleeve assembly 240. When the hinge shaft 223 moves from the accommodating space 247 to the outside of the first opening 245, the opening of the first opening 245 gradually increases. When the hinge shaft 223 moves from the first opening 245 to the inside of the accommodating space 247, the opening of the first opening 245 gradually decreases.

[0035] like Figure 5 As shown, the actuating assembly 260 includes a linkage member 261 arranged at the second opening 246, the cross-sectional area of ​​one end of the linkage member 261 is larger than the cross-sectional area of ​​the other end, and when the hinge shaft 223 moves from the accommodating space 247 to the outside of the first opening 245, the linkage member 261 moves in the second opening 246 and the cross-sectional area of ​​the part in the second opening 246 gradually decreases, and at the same time, under the action of the first elastic member 248, the opening size of the second opening 246 gradually becomes smaller.

[0036] The linkage member 261 extends radially along the sleeve assembly 240, and during the movement of the linkage member 261 in the second opening 246, the linkage member 261 is always disposed in the second opening 246. During the movement of the linkage member 261, the movement distance of the linkage member 261 in the second opening 246 is substantially the same, and accordingly, the size of the opening opened each time is ensured to be the same.

[0037] In one embodiment of the present invention, in order to prevent the linkage member 261 from being separated from the shaft sleeve assembly 240 when moving toward the outside of the first opening 245 , the linkage member 261 extends radially along the shaft sleeve assembly 240 and is always disposed in the second opening 246 .

[0038] Furthermore, in order for the linkage member 261 to move smoothly in the second opening 246 and satisfy the requirement that the cross-sectional area at one end is larger than the cross-sectional area at the other end, optionally, the linkage member 261 is a conical structure radially penetrated into the second opening 246 along the sleeve assembly.

[0039] Optionally, the linkage member 261 may be configured as a conical pin. Of course, the linkage member 261 also has other implementations, which will not be described one by one here.

[0040] In one embodiment of the present invention, the large end of the linkage member 261 is arranged toward the inner side of the accommodating space 247, and a matching surface 262 matching with the hinge shaft 223 is formed at the large end. The matching surface 262 can be set as a smooth curved surface matching with the outer peripheral surface of the hinge shaft 223. When the linkage member 261 rotates around the hinge shaft 223, the matching surface 262 is always closely fitted with the outer peripheral surface of the hinge shaft 223, thereby preventing the door body 140 from falling off from the box body 120, and improving user satisfaction.

[0041] In one embodiment of the present invention, in order to enable the linkage member 261 to move toward the first opening along with the hinge shaft 223 when the hinge shaft 223 moves toward the outside of the first opening 245, the actuating assembly 260 further includes an actuating member 263 disposed at one end of the linkage member 261, and one end of the actuating member 263 is connected to the linkage member 261, and the other end is connected to the door body 140. When the hinge shaft moves from the accommodating space 247 toward the outside of the first opening 245, the actuating member 263 drives the linkage member 261 to move toward the first opening 245. The actuating member 263 can also limit the moving distance of the linkage member 261, thereby ensuring that the linkage member 261 is always disposed in the second opening 246, thereby preventing the linkage member 261 from detaching from the shaft sleeve assembly 240.

[0042] In this embodiment, the actuating member 263 may be configured as a second elastic member connected to an end of the linkage member 261 away from the hinge shaft 223. Optionally, the actuating member 263 may be configured as a compression spring.

[0043] In one embodiment of the present invention, in order to ensure that the movement direction of the actuating assembly 260 is always from the second opening 246 to the first opening 245, a guide hole 144 for the actuating assembly 260 to move is further provided on the door body 140, and the guide hole 144 intersects with the receiving groove 142 and is perpendicular to the contact surface between the door body 140 and the box body 120. Optionally, the guide hole 144 is provided in the middle of the receiving groove 142.

[0044] During use of the two-way door refrigeration device 100, when the user opens the door from the left side, the door body 140 rotates around the axis of the hinge shaft 223 in the hinge structure 200 installed on the right side of the box body 120. At this time, when the user pulls the door body 140, the hinge shaft 223 in the hinge structure 200 installed on the left side of the box body 120 moves from the accommodating space 247 to the first opening 245. At the same time, the linkage member 261 moves toward the first opening 245 driven by the actuating member 263. Since the cross-sectional area of ​​the linkage member 261 in the second opening 246 gradually decreases during the movement, the first clamping member 241 and the second clamping member 242 are acted upon by the first elastic member 248, so that the opening width of the first opening 245 gradually increases until the hinge shaft 223 is completely moved out of the first opening.

[0045] When the user closes the door, the first opening 245 is always large enough to allow the hinge shaft 223 to pass through when the door body 140 is open. When the hinge shaft 223 moves from the first opening 245 toward the accommodating space 247, the hinge shaft 223 contacts the mating surface 262 of the linkage member 261. At this time, the hinge shaft 223 and the linkage member 261 move toward the second opening together. At this time, the cross-sectional area of ​​the linkage member 261 in the second opening 246 gradually increases, and at the same time, the width of the first opening gradually decreases, thereby completing the closing of the door body 140.

[0046] Among them, when the user opens the door from the left side, the linkage part 261 installed on the right side of the two-way door refrigeration equipment 100 is always in close contact with the outer peripheral surface of the hinge shaft 223 with a smooth mating surface 262, and rotates around the hinge shaft 223 to prevent the door body 140 from falling off from the box body 120 during the opening or closing process of the door body 140.

[0047] Similarly, when the user opens the door from the right side, the operation process of the entire device is similar and will not be described in detail here.

[0048] In summary, the beneficial effects of the present invention are as follows: the two-way door opening refrigeration equipment 100 provided by the present invention can realize the rapid switching of the door opening direction to meet the simultaneous use of users with different usage habits; at the same time, the hinge structure 200 of the present invention realizes the entry or removal of the hinge shaft 223 through the opening and closing of the first opening 245 between the first clamping member 241 and the second clamping member 242, thereby completing the opening or closing of the door body 140. The hinge structure 200 is a purely mechanical structure, with small implementation limitations, low implementation cost, and relatively high feasibility. In addition, the control method of the two-way door opening refrigeration equipment 100 provided by the present invention is flexible, so that the door body 140 is not in danger of falling off during the opening and closing process.

[0049] 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.

[0050] 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.
