DETAILED DESCRIPTION

[0032] 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.

[0033] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "front", "rear", "upper", "lower", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0034] Embodiment 1

[0035] like Figures 1 to 3 As shown, in one embodiment of the present invention, a refrigeration appliance 10 is provided, and the refrigeration appliance 10 includes a box body 11, a door body 12, and a door opening device 13. A storage room is provided in the box body 11, the door body 12 is used to open and close the storage room, and the door opening device 13 is used to open the door body 12. The door opening device 13 includes a pressing component 131, an ejection component 132, and a fluid pipeline 133 connecting the pressing component 131 and the ejection component 132. The ejection component 132 has a push rod 1321 that moves along the front and rear direction of the box body 11.

[0036] When the pressing assembly 131 is subjected to a force, the fluid in the pressing assembly 131 flows to the ejection assembly 132 through the fluid pipeline 133. The fluid pushes the ejector rod 1321 to move against the door body 12 or the box body 11, so that the door body 12 can rotate relative to the box body 11, thereby realizing the opening of the door body 12 and improving the user's comfort.

[0037] When the door body 12 is closed, the user can push the door body 12 to rotate relative to the box body 11, so that the door body 12 or the box body 11 can abut against the top rod 1321, so that the top rod 1321 pushes the fluid to flow to the pressing assembly 131 through the fluid pipeline 133, and the pressing assembly 131 is reset to facilitate the next opening of the door body 12. In addition, the refrigeration appliance 10 can also meet the appearance requirements of no handle, that is, the door body 12 is not provided with a handle or an invisible handle is provided, thereby improving the appearance of the refrigeration appliance 10.

[0038] Optionally, the fluid may be hydraulic oil, water or gas. The fluid may be selected as required, and any technical solution that is the same or similar to the present embodiment is within the protection scope of the present invention.

[0039] Furthermore, the pressing assembly 131 has a pressing portion 1311 for bearing the force, and the pressing portion 1311 can be exposed to the outside to facilitate the user to press. During the use of the pressing assembly 131, the user can press the pressing portion 1311 of the pressing assembly 131 to make the fluid in the pressing assembly 131 flow to the ejection assembly 132.

[0040] Among them, the movement stroke of the pressing part 1311 is smaller than the movement stroke of the top rod 1321, which can realize a greater degree of opening of the door body 12 while ensuring a smaller pressing distance, and can enable the door opening device 13 to drive the door body 12 to rotate at a larger angle. In some embodiments, the force can also be applied to the pressing part 1311 by other driving elements. Therefore, all technical solutions that are the same or similar to this embodiment are covered within the protection scope of the present invention.

[0041] In this embodiment, the ejection assembly 132 includes an ejection seat 1323 defining an ejection cavity 1322, a transmission member 1324 disposed in the ejection cavity 1322, and the transmission member 1324 is connected to the ejector rod 1321. The pressing assembly 131 includes a pressing seat 1313 defining a pressing cavity 1312, an actuating member 1314 disposed in the pressing cavity 1312, and the actuating member 1314 is connected to the pressing portion 1311. The fluid can be stored in the ejection cavity 1322, the pressing cavity 1312, and the fluid pipeline 133.

[0042] When the pressing part 1311 is subjected to a force, the pressing part 1311 can drive the actuator 1314 to move, so that the fluid in the pressing chamber 1312 flows to the ejection chamber 1322 through the fluid pipeline 133, and then the fluid can push the transmission part 1324 to move, so that the transmission part 1324 drives the ejector rod 1321 to move, thereby realizing the opening of the door body 12.

[0043] Optionally, the pressing portion 1311 can be configured as a plate-like structure, and the area of ​​the plate-like structure can be configured as required, as long as the comfort level of the user when pressing can be improved.

[0044] Furthermore, the ejection assembly 132 and the pressing assembly 131 may adopt a hydraulic cylinder or a cylinder structure. At least one of the actuating member 1314 and the transmission member 1324 is configured as a piston 134, and the piston 134 is movably disposed in the ejection chamber 1322 or the pressing chamber 1312. The ejection seat 1323 is provided with a fluid inlet end 1325 for fluid to enter or flow out of the ejection chamber 1322, and a push rod outlet 1326 for the push rod 1321 to slide. The pressing seat 1313 is provided with a fluid inlet end 1315 for fluid to enter or flow out of the pressing chamber 1312, and a pressing opening 1316 for the pressing portion 1311 to slide.

[0045] One end of the fluid pipeline 133 can be connected to the fluid inlet end 1325, and the other end of the fluid pipeline 133 can be connected to the fluid inlet end 1315. A spring 1331 is also provided at the connection between the fluid pipeline 133 and the fluid inlet end 1325 and the fluid inlet end 1315, and the spring 1331 can be wound around the outside of the fluid pipeline 133 to strengthen the connection between the fluid pipeline 133 and the fluid inlet end 1315 and the fluid inlet end 1325, so as to prevent the fluid from leaking from the fluid inlet end 1315 and the fluid inlet end 1325.

[0046] In this embodiment, the actuating member 1314 and the transmission member 1324 can both be configured as pistons 134. For ease of description, the piston 134 in the ejection chamber 1322 can be an ejection piston, and the piston 134 in the pressing chamber 1312 can be a pressing piston. The action area of ​​the pressing piston is larger than the action area of ​​the ejection piston, so as to ensure that the movement stroke of the pressing portion 1311 is smaller than the movement stroke of the ejector rod 1321, and the door body 12 can be opened with a relatively small force.

[0047] In this embodiment, the door body 12 is rotatably connected to the box body 11. The refrigeration appliance 10 further includes a pivot shaft connecting the box body 11 and the door body 12. The pressing assembly 131 may be disposed on the door body 12, the ejecting assembly 132 may be disposed on the box body 11, and the fluid pipeline 133 may pass through the pivot shaft to connect the ejecting assembly 132 and the pressing assembly 131.

[0048] Furthermore, the box body 11 has a pivot side 112 pivotally connected to the door body 12 and an open side 113 relatively far away from the pivot side 112, and the pivot side 112 and the open side 113 are arranged along the left and right directions of the box body 11. The ejection assembly 132 can be arranged on the open side 113, so that the door body 12 can be opened with a small force, which helps to improve the user's comfort. In some embodiments, the pressing assembly 131 and the ejection assembly 132 can also be arranged on the door body 12, or the pressing assembly 131 and the ejection assembly 132 can also be arranged on the box body 11.

[0049] In this embodiment, the ejector assembly 132 may be disposed at the top of the box body 11. The door opening device 13 further includes a box body 135, in which a receiving cavity is disposed, and the ejector assembly 132 may be disposed in the box body 135, and a side wall of the box body 135 facing the door body 12 is provided with an extension hole for the ejector rod 1321 to extend, thereby improving the appearance of the refrigeration appliance 10.

[0050] During the opening process of the door body 12, the user can press the pressing portion 1311 to push the pressing piston to move, and the ejection piston is pushed to move by the fluid, and the ejection piston drives the ejector rod 1321 to move, and the ejector rod 1321 extends out of the box body 135 to push against the door body 12 to open the door body 12. When the door body 12 needs to be closed, the user can rotate the door body 12 until the door body 12 abuts against the ejector rod 1321, so that the ejection assembly 132 and the pressing assembly 131 return to their original positions, so as to facilitate the next opening of the door body 12.

[0051] Embodiment 2

[0052] like Figure 4 As shown, in one embodiment of the present invention, a refrigeration appliance is further provided. Here, only the distinguishing features of this embodiment compared with the first embodiment are described, and the same parts are not described again. In this embodiment, at least one of the transmission member 2324 and the actuating member is configured as a telescopic bag 236, and the telescopic bag 236 is configured in the ejection cavity 2322 or the pressing cavity, and the cavity in the telescopic bag 236 is connected to the fluid pipeline 233. Figure 4 The schematic diagram of the internal structure of the ejection assembly 232 provided in this embodiment is shown. The schematic diagram of the internal structure of the pressing assembly is similar to the schematic diagram of the internal structure of the ejection assembly 232, which can be referred to Figure 4 .

[0053] Furthermore, the telescopic bag 236 can be set as a rubber piece. The telescopic bag 236 is elastic and can be deformed under the action of fluid or force to drive the pressing part and the ejector 2321 to move. In some embodiments, the telescopic bag 236 can also be set as a plastic piece, which can only realize the transmission between the pressing component and the ejection component 232.

[0054] Furthermore, the ejector rod 2321 may be configured as a plastic part, so that the ejector rod 2321 has a high working strength and hardness, and meets the working requirements of the ejection assembly 232. Optionally, the telescopic bag 236 may be configured as an integral part with the ejector rod 2321.

[0055] In this embodiment, the transmission member 2324 and the actuating member may both be configured as a telescopic bag 236. For the convenience of description, the telescopic bag 236 in the ejection cavity 2322 may be an ejection bag, and the telescopic bag 236 in the pressing cavity may be a pressing bag. When the outer diameter of the ejection bag is the same as the inner diameter of the ejection cavity 2322, and the outer diameter of the pressing bag is the same as the inner diameter of the pressing cavity, the effective area of ​​the ejection bag may be understood as the cross-sectional area of ​​the ejection cavity 2322, and the effective area of ​​the pressing bag may be understood as the cross-sectional area of ​​the pressing cavity.

[0056] In this embodiment, the pressing part can be connected to the pressing bag. The pressing part can not only facilitate the user to press, increase the area that the user can press, and help improve the comfort of the user when pressing the pressing component, but also protect the pressing bag to prevent the pressing bag from being damaged by external objects and causing fluid leakage.

[0057] Embodiment 3

[0058] like Figures 5 to 7 As shown, in one embodiment of the present invention, a refrigeration appliance 30 is also provided. Here, only the distinguishing features of this embodiment compared with the first embodiment are described, and the same parts are not introduced again. In this embodiment, the door opening device 33 also includes a connecting rod structure 34 that is rotatably arranged relative to the box body 31. The connecting rod structure 34 includes a driven end 342 and an active end 341 connected to the top rod. The connecting rod structure 34 is arranged in one of the box body 31 and the door body 32, and the driven end 342 has an abutting state with the other of the box body 31 and the door body 32, and the driven end 342 also has a disengaged state with the other of the box body 31 and the door body 32.

[0059] When the pressing assembly is subjected to a force, the fluid in the pressing assembly flows to the ejection assembly 332 through the fluid pipeline, and the ejector rod drives the connecting rod structure 34 to rotate, so that the driven end 342 pushes against the box body 31 or the door body 32, so that the door body 32 opens. The ejector rod can be in contact with the active end 341, or can be hinged to the active end 341, as long as the movement of the ejector rod can be transmitted to the connecting rod structure 34.

[0060] Optionally, the push rod may be arranged along the front-to-back direction of the box body 31 or along the first direction. It should be noted that the first direction is arranged at a non-zero angle with the front-to-back direction of the box body 31 .

[0061] Specifically, the ejection assembly 332 is disposed on the box body 31, the connecting rod structure 34 is disposed on the door body 32, and the driven end 342 can push against the box body 31 to open the door body 32. The connecting rod structure 34 includes a connecting shaft 343, a first section 344 and a second section 345 extending radially from the connecting shaft 343, the connecting shaft 343 is rotatably connected to the box body 31 or the door body 32, the first section 344 defines a driving end 341, and the second section 345 defines a driven end 342.

[0062] Furthermore, the first section 344 and the second section 345 are arranged at a non-zero angle around the connecting shaft 343, so that the door body can be opened when rotating at a relatively small angle. In addition, the distance from the connecting shaft 343 to the active end 341 is smaller than the distance from the connecting shaft 343 to the driven end 342, so that the force generated by the push rod can be amplified, so that the user can open the door body 32 with relatively small force, which helps to improve the user's comfort. In addition, the lengths of the first section 344 and the second section 345 can be set as needed, as long as the door body 32 can be guaranteed to have a relatively large opening angle.

[0063] In this embodiment, the connecting rod structure 34 also includes a mounting shaft 346 connected to the box body 31 or the door body 32, and the connecting shaft 343 is provided with a through hole 3431 for the mounting shaft 346 to pass through. That is, the mounting shaft 346 can be fixedly connected to the box body 31 or the door body 32, and the connecting shaft 343 can be sleeved on the mounting shaft 346 through the through hole 3431, so as to reduce the wear of the box body 31 or the door body 32 during the rotation of the connecting rod structure 34, which helps to extend the service life of the door opening device 33. Specifically, the ejection assembly 332 can be arranged on the box body 31, the connecting rod structure 34 is arranged on the door body 32, and the connecting shaft 343 can be fixed to the door body 32 through the mounting shaft 346.

[0064] Furthermore, the connecting rod structure 34 also includes a stop pin 347, and the mounting shaft 346 is provided with a pin hole for the stop pin 347 to pass through. The pin hole is provided at one end of the mounting shaft 346 away from the door body 32. When the connecting shaft 343 is sleeved on the mounting shaft 346, the stop pin 347 is inserted into the pin hole, thereby achieving the connection between the connecting shaft 343 and the mounting shaft 346, and preventing the connecting shaft 343 from being separated from the mounting shaft 346.

[0065] Optionally, the limiting pin 347 may be configured as an R-shaped pin.

[0066] In this embodiment, the connecting rod structure 34 further includes a reset elastic member 348. In the abutting state, when the ejection assembly 332 drives the connecting rod structure 34 to rotate relative to the box body 31 to open the door body 32, the deformation of the reset elastic member 348 increases.

[0067] Further, the resetting elastic member 348 is configured as a spring, one end of which is connected to the connecting rod structure 34, and the other end of which is connected to the box body 31 or the door body 32. The spring can be sleeved on the outside of the mounting shaft 346, and the connecting shaft 343 can be provided with a limiting portion for fixing the end of the spring. The limiting portion can be configured as a protrusion or a limiting hole, etc.

[0068] When the push rod pushes the active end 341 and the driven end 342 to rotate relative to the door body 32, the deformation of the spring increases. After the door body 32 is opened, the deformation of the spring is restored to drive the active end 341 and the driven end 342 to rotate, so that the push rod is restored to the initial position, and then the fluid in the ejection assembly 332 flows to the pressing assembly to facilitate the next opening of the door body 32.

[0069] In some embodiments, the door opening device 33 can also cause the box body 31 to press against the driven end 342 when the user closes the door body 32, pushing the active end 341 and the driven end 342 to rotate relative to the door body 32, thereby restoring the ejector rod to its original position and allowing the fluid in the ejection assembly 332 to flow to the pressing assembly to facilitate the next opening of the door body 32.

[0070] Embodiment 4

[0071] like Figure 8 and Fig. 9 As shown, in one embodiment of the present invention, a refrigeration appliance 40 is also provided. Here, only the distinguishing features of this embodiment compared with the third embodiment are described, and the same parts are not introduced again. The connecting rod structure 44 includes a first rotating shaft 443, a second rotating shaft 444 arranged along the radial direction of the first rotating shaft 443, a third section 445 and a fourth section 446 extending radially from the first rotating shaft 443, and a fifth section 447 and a sixth section 448 extending radially from the second rotating shaft 444. The third end defines a driving end 441, the fourth section 446 and the fifth section 447 are hinged, and the sixth section 448 defines a driven end 442.

[0072] Specifically, the connecting rod structure 44 and the ejection assembly 432 are both disposed on the box body 41. When the ejector rod 4321 pushes the active end 441 to rotate relative to the box body 41, the active end 441 drives the fourth section 446 to rotate through the first rotating shaft 443, and the fourth section 446 drives the fifth section 447 to move, thereby causing the driven end 442 to rotate so that the sixth section 448 extends out to push against the door body 42, thereby realizing the opening of the door body 42.

[0073] Furthermore, the distance from the first rotating shaft 443 to the active end 441 is L1, the length of the fourth section 446 is L2, the length of the fifth section 447 is L3, and the distance from the second rotating shaft 444 to the driven end 442 is L4, wherein L1<L2, L3<L4, thereby amplifying the force generated by the push rod 4321, allowing the user to open the door body 42 with less force, which helps to improve the user's comfort.

[0074] In this embodiment, the first rotating shaft 443 and the second rotating shaft 444 can be fixed to the box body 41 in a similar manner to the third embodiment described above. The connecting rod structure 44 also includes a first positioning shaft and a second positioning shaft connected to the box body 41 or the door body 42, and the first rotating shaft 443 and the second rotating shaft 444 are correspondingly provided with through holes for the first positioning shaft and the second positioning shaft to pass through. That is, the first rotating shaft 443 is fitted on the first positioning shaft through the through hole, and the second rotating shaft 444 is fitted on the second positioning shaft through the through hole.

[0075] In this embodiment, the box body is also provided with an opening for the driven end 442 to pass through, and the top rod 4321 pushes the active end 441 and the driven end 442 to rotate relative to the door body 42 or the box body 41, and the driven end 442 can extend from the opening, so that the driven end 442 extends out of the joint surface between the door body 42 and the box body 41 to resist the box body 41 or the door body 42, thereby realizing the opening of the door body 42.

[0076] In summary, the beneficial effect of the present invention is that during the use of the above-mentioned refrigeration appliance 10, when the pressing component 131 is subjected to a force, the fluid in the pressing component 131 flows to the ejection component 132 through the fluid pipeline 133, and the fluid pushes the ejector rod 1321 to move along the front and rear direction of the box body 11 to push against the door body 12 or the box body 11, so that the door body 12 rotates relative to the box body 11 to realize the opening of the door body 12, which can improve the user's comfort.

[0077] 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.
