In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0037] Embodiment 1

[0038] like Figures 1 to 3As shown, in one embodiment of the present invention, a refrigeration appliance 10 is provided. The refrigeration appliance 10 includes a box body 11, a door body 12, and a door opening device 13. A storage chamber is provided in the box body 11, and the door body 12 is used to open and close the storage chamber. The door opening device 13 includes a pressing component 131, an ejection component 132, a connecting rod structure 14 rotatably arranged relative to the box body 11, and a fluid pipeline 133 connecting the pressing component 131 and the ejection component 132. The ejection component 132 has an ejector rod 1321 that is rotatably arranged relative to the box body 11.

[0039] 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.

[0040] In this embodiment, the connecting rod structure 14 includes a driven end 142 and an active end 141 connected to the top rod 1321. The connecting rod structure 14 is disposed in one of the box body 11 and the door body 12, and the driven end 142 has an abutting state with the other of the box body 11 and the door body 12, and the driven end 142 also has a disengaged state with the other of the box body 11 and the door body 12.

[0041] When the pressing assembly 131 is subjected to a force, the fluid in the pressing assembly 131 flows to the ejecting assembly 132 through the fluid pipeline 133, and the ejector rod 1321 drives the connecting rod structure 14 to rotate, so that the driven end 142 pushes against the box body 11 or the door body 12, so that the door body 12 opens. The ejector rod 1321 can be in contact with the active end 141, or can be hinged to the active end 141, as long as the movement of the ejector rod 1321 can be transmitted to the connecting rod structure 14.

[0042] Further, the ejection assembly 132 is disposed on the box body 11, the connecting rod structure 14 is disposed on the door body 12, and the driven end 142 can push against the box body 11 to open the door body 12. The connecting rod structure 14 includes a connecting shaft 143, a first section 144 and a second section 145 extending radially from the connecting shaft 143, the connecting shaft 143 is rotatably connected to the box body 11 or the door body 12, the first section 144 defines a driving end 141, and the second section 145 defines a driven end 142.

[0043] Furthermore, the first section 144 and the second section 145 are arranged at a non-zero angle around the connecting shaft 143, so that the driven end 142 can abut against the box body 11 when the rotation angle is small, so that the door body can be opened. The distance from the connecting shaft 143 to the active end 141 is smaller than the distance from the connecting shaft 143 to the driven end 142, so that the force of the top rod 1321 can be amplified, so that the user can open the door body 12 with less force, which helps to improve the user's comfort. In addition, the lengths of the first section 144 and the second section 145 can be set as needed, as long as it can ensure that the door body 12 has a larger opening angle.

[0044] Optionally, the top rod 1321 can be arranged along the front-to-back direction of the box body 11, or can be arranged 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 11.

[0045] In this embodiment, the connecting rod structure 14 also includes a mounting shaft 146 connected to the box body 11 or the door body 12, and the connecting shaft 143 is provided with a through hole 1431 for the mounting shaft 146 to pass through. That is, the mounting shaft 146 can be fixedly connected to the box body 11 or the door body 12, and the connecting shaft 143 can be sleeved on the mounting shaft 146 through the through hole 1431, so as to reduce the wear of the box body 11 or the door body 12 during the rotation of the connecting rod structure 14, which helps to extend the service life of the door opening device 13. Specifically, the ejection assembly 132 can be arranged on the box body 11, the connecting rod structure 14 is arranged on the door body 12, the connecting shaft 143 can be fixed to the door body 12 through the mounting shaft 146, and the driven end 142 pushes against the box body 11 to realize the opening of the door body 12.

[0046] Furthermore, the connecting rod structure 14 further includes a stop pin 147, and the mounting shaft 146 is provided with a pin hole for the stop pin 147 to pass through. The pin hole is provided at one end of the mounting shaft 146 away from the door body 12, so as to facilitate the fixing of the connecting shaft 143 to the mounting shaft 146. When the connecting shaft 143 is sleeved on the mounting shaft 146, the stop pin 147 is inserted into the pin hole, thereby realizing the connection between the connecting shaft 143 and the mounting shaft 146, and preventing the connecting shaft 143 from being separated from the mounting shaft 146.

[0047] Optionally, the limiting pin 147 may be configured as an R-shaped pin.

[0048] In this embodiment, the connecting rod structure 14 further includes a reset elastic member 148. When the driven end 142 is in the abutment state and the ejection assembly 132 drives the connecting rod structure 14 to rotate relative to the box body 11 to open the door body 12, the deformation of the reset elastic member 148 increases.

[0049] Further, the resetting elastic member 148 is configured as a spring, one end of which is connected to the connecting rod structure 14, and the other end of which is connected to the box body 11 or the door body 12. In this embodiment, the spring can be sleeved on the outside of the mounting shaft 146, and the connecting shaft 143 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.

[0050] When the ejector 1321 pushes the active end 141 and the driven end 142 to rotate relative to the door body 12, the deformation of the spring increases. After the door body 12 is opened, the deformation of the spring is restored to drive the active end 141 and the driven end 142 to rotate, so that the ejector 1321 is restored to the initial position, and then the fluid in the ejection assembly 132 flows to the pressing assembly 131, so as to facilitate the next opening of the door body 12.

[0051] In some embodiments, the door opening device 13 can also make the box body 11 press against the driven end 142 when the user closes the door body 12, pushing the active end 141 and the driven end 142 to rotate relative to the door body 12, so that the push rod 1321 returns to its original position, and the fluid in the ejection assembly 132 flows to the pressing assembly 131, so as to facilitate the next opening of the door body 12.

[0052] like Figure 4 and Figure 5 As shown, the pressing assembly 131 has a pressing portion 1311 for receiving 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] In this embodiment, the actuating member 1314 and the transmission member 1324 may both be configured as a piston 134. For the convenience of description, the piston 134 in the ejection chamber 1322 may be an ejection piston 134, and the piston 134 in the pressing chamber 1312 may be a pressing piston 134. The action area of ​​the pressing piston 134 is larger than the action area of ​​the ejection piston 134, 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 at the same time, the door body 12 can be opened with a relatively small action force.

[0060] 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 can be disposed on the door body 12, the ejecting assembly 132 can be disposed on the box body 11, and the fluid pipeline 133 can pass through the pivot shaft to connect the ejecting assembly 132 and the pressing assembly 131.

[0061] 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.

[0062] 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.

[0063] During the opening process of the door body 12, the user can press the pressing part 1311 to push the pressing piston 134 to move, and the ejection piston 134 is pushed to move by the fluid. The ejection piston 134 drives the ejector rod 1321 to move, and the ejector rod 1321 pushes the active end 141 and the driven end 142 to rotate to push against the box body 11, thereby realizing automatic opening of the door body 12.

[0064] Embodiment 2

[0065] like Figure 6 and Figure 7 As shown, in one embodiment of the present invention, a refrigeration appliance 20 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. The connecting rod structure 24 includes a first rotating shaft 243, a second rotating shaft 244 arranged along the radial direction of the first rotating shaft 243, a third section 245 and a fourth section 246 extending radially from the first rotating shaft 243, and a fifth section 247 and a sixth section 248 extending radially from the second rotating shaft 244. The third section 245 defines a driving end 241, the fourth section 246 and the fifth section 247 are hinged, and the sixth section 248 defines a driven end 242.

[0066] Specifically, the connecting rod structure 24 and the ejection assembly 232 are both disposed on the box body 21. When the ejector rod 2321 pushes the active end 241 to rotate relative to the box body 21, the active end 241 drives the fourth section 246 to rotate through the first rotating shaft 243, and the fourth section 246 drives the fifth section 247 to move, thereby causing the driven end 242 to rotate so that the sixth section 248 extends out to push against the door body 22, thereby realizing the opening of the door body 22.

[0067] Furthermore, the distance from the first rotating shaft 243 to the active end 241 is L1, the length of the fourth section 246 is L2, the length of the fifth section 247 is L3, and the distance from the second rotating shaft 244 to the driven end 242 is L4, wherein L1<L2, L3<L4, thereby amplifying the force generated by the push rod 2321, allowing the user to open the door body 22 with less force, which helps to improve the user's comfort.

[0068] In this embodiment, the first rotating shaft 243 and the second rotating shaft 244 can be fixed to the box body 21 in a similar manner to the third embodiment. Specifically, the connecting rod structure 24 also includes a first positioning shaft and a second positioning shaft connected to the box body 21 or the door body 22, and the first rotating shaft 243 and the second rotating shaft 244 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 243 is sleeved on the first positioning shaft through the through hole, and the second rotating shaft 244 is sleeved on the second positioning shaft through the through hole.

[0069] In this embodiment, the connecting rod structure and the ejection assembly are both arranged on the box body, so that the driven end pushes against the door body to open the door body. The box body is also provided with an opening for the driven end 242 to pass through, and when the ejector rod 2321 pushes the active end 241 and the driven end 242 to rotate relative to the door body 22 or the box body 21, the driven end 242 can extend from the opening, so that the driven end 242 extends out of the joint surface between the door body 22 and the box body 21 to resist the box body 21 or the door body 22, so as to open the door body 22.

[0070] Embodiment 3

[0071] like Figure 8 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 3324 and the actuating member is configured as a telescopic bag 336, and the telescopic bag 336 is configured in the ejection cavity 3322 or the pressing cavity, and the cavity in the telescopic bag 336 is connected to the fluid pipeline 333. Figure 8 The internal structure schematic diagram of the ejection assembly 332 provided in this embodiment is shown. The internal structure schematic diagram of the pressing assembly is similar to the internal structure schematic diagram of the ejection assembly 332, which can be referred to Figure 8 .

[0072] Furthermore, the telescopic bag 336 can be set as a rubber piece. The telescopic bag 336 is elastic and can be deformed under the action of fluid or force to drive the pressing part and the ejector 3321 to move. In some embodiments, the telescopic bag 336 can also be set as a plastic piece, which can only realize the transmission between the pressing component and the ejection component 332.

[0073] Furthermore, the ejector rod 3321 may be configured as a plastic part, so that the ejector rod 3321 has high working strength and hardness, meeting the working requirements of the ejection assembly 332. Optionally, the telescopic bag 336 may be configured as an integral part with the ejector rod 3321.

[0074] In this embodiment, the transmission member 3324 and the actuating member may both be configured as a telescopic bag 336. For the convenience of description, the telescopic bag 336 in the ejection cavity 3322 may be an ejection bag, and the telescopic bag 336 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 3322, 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 3322, and the effective area of ​​the pressing bag may be understood as the cross-sectional area of ​​the pressing cavity.

[0075] 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 telescopic bag 336 to prevent the telescopic bag 336 from being damaged by external objects and causing fluid leakage.

[0076] To sum up, the beneficial effect of the present invention is that during the use of the above-mentioned refrigeration appliance, when the pressing assembly is subjected to a force, the fluid in the pressing assembly flows to the ejection assembly through the fluid pipeline to push the ejector rod to move, and the ejector rod pushes the active end and the driven end to rotate relative to the box body, so that the driven end pushes against the door body or the box body to achieve the opening of the door body. When the ejector rod moves a certain distance, the opening angle of the door body can be increased, which helps to improve the user comfort.
