[0029] 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.

[0030] 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.

[0031] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a refrigeration appliance 100, which includes a box body 11, a door body 12, and a door opening device 20. A storage chamber is provided in the box body 11, and the door body 12 is pivotally connected to the box body 11 to open and close the storage chamber. The door opening device 20 includes a pressing component 21, an ejecting component 22, a gear transmission mechanism 23 matched with the ejecting component 22, and a fluid pipeline 28 connecting the pressing component 21 and the ejecting component 22.

[0032] Further, one of the door body 12 and the box body 11 is provided with a gear transmission mechanism 23, and the other of the door body 12 and the box body 11 is provided with a meshing portion 121 matched with the gear transmission mechanism 23, and the meshing portion 121 is located on the pivot axis of the door body 12 rotating relative to the box body 11. When the pressing assembly 21 is subjected to a force, the fluid in the pressing assembly 21 flows to the ejection assembly 22 through the fluid pipeline 28, and the ejection assembly 22 drives the gear transmission mechanism 23 to move to drive the door body 12 to rotate through the meshing portion 121, thereby realizing the opening of the door body 12.

[0033] like Figures 3 to 6 As shown, the gear transmission mechanism 23 includes a transmission gear 231 matched with the meshing portion 121, and a clutch structure 232 provided between the transmission gear 231 and the meshing portion 121. During the operation of the gear transmission structure, the clutch structure 232 can be used to connect or disconnect the transmission cooperation between the transmission gear 231 and the meshing portion 121.

[0034] Specifically, the maximum angle at which the ejection assembly 22 drives the door body 12 to open is the first angle, and the angle at which the door body 12 is fully opened is the second angle, and the second angle is greater than the first angle. When the ejection assembly 22 drives the door body 12 to rotate to the first angle, when the user needs to continue to open the door body 12, that is, during the process of rotating the door body 12 from the first angle to the second angle, the clutch structure 232 can separate the transmission gear 231 and the meshing portion 121, so as to prevent the door body 12 from continuing to open and affecting the movement of the components between the transmission gear 231 and the ejection assembly 22, thereby reducing the resistance to the continued opening of the door body 12, and further enabling the continued opening of the door body 12 to be achieved with less force. Of course, in some embodiments, the maximum angle at which the ejection assembly 22 drives the door body 12 to open can also be the angle at which the door body 12 is fully opened.

[0035] In this embodiment, the gear transmission mechanism 23 can be arranged on the housing 11, and the meshing portion 121 can be correspondingly arranged on the door body 12. The meshing portion 121 includes an internal gear 1211 and an external gear 1212 meshed with the internal gear 1211, and the internal gear 1211 can be installed on the door body 12. The gear transmission mechanism 23 also includes a gear shaft 233 connecting the transmission gear 231 and the external gear 1212, and a fixing seat 236 for fixing the gear shaft 233, the fixing seat 236 is installed on the housing, and the fixing seat 236 is provided with a through hole 2361 for the gear shaft 233 to pass through. The clutch structure 232 includes a first stopper 2321 and a second stopper 2322 matched with the first stopper 2321, the first stopper 2321 is arranged on the gear shaft 233, and the second stopper 2322 can be arranged on the external gear 1212 or the transmission gear 231. The axis of the gear shaft 233 may coincide with the pivot axis of the door body 12 , that is, the gear shaft 233 is located on the pivot axis of the door body 12 .

[0036] When the ejection assembly 22 moves to the maximum stroke and the door body 12 continues to open, the first stopper 2321 and the second stopper 2322 are disengaged. That is, when the door body 12 closes and moves to the first angle, the first stopper 2321 and the second stopper 2322 abut against each other to realize the transmission from the transmission gear 231 to the outer gear 1212; when the door body 12 moves from the first angle to the second angle, the first stopper 2321 and the second stopper 2322 are disengaged to prevent the structure between the transmission gear 231 and the ejection assembly 22 from continuing to operate during the continuous opening of the door body 12. In some embodiments, the gear transmission mechanism 23 can also be provided on the door body 12, and the meshing portion 121 is correspondingly provided on the box body 11.

[0037] Further, a plurality of first stoppers 2321 and second stoppers 2322 may be provided and evenly arranged around the pivot axis. It should be noted that the contact surface between the first stopper 2321 and the second stopper 2322 may be provided as a plane passing through the axis, or as an inclined surface. The number and position of the first stopper 2321 and the second stopper 2322 may be provided correspondingly. Optionally, the first stopper 2321 and the second stopper 2322 may be provided as three groups.

[0038] In this embodiment, the gear transmission mechanism 23 includes a rack 234 connected to the ejection assembly 22, and a gear set 235 disposed between the rack 234 and the transmission gear 231. The rack 234 is slidably disposed relative to the box body 11. Optionally, the rack 234 can slide along the left and right directions of the box body 11.

[0039] Furthermore, the door opening device 20 also includes a slide 24, and a sliding structure 241 connecting the slide 24 and the rack 234. The sliding structure 241 includes a slide groove 2411 provided on one of the slide 24 and the rack 234, and a sliding member 2412 provided on the other of the slide 24 and the rack 234, and the sliding member 2412 cooperates with the slide groove 2411. Specifically, the slide 24 can be fixedly installed on the top of the box body 11, and the sliding member 2412 can be provided on the slide 24, and the sliding member 2412 can be provided as a V-shaped protrusion. The slide groove 2411 can be provided correspondingly to the rack 234, and the shapes of the slide groove 2411 and the sliding member 2412 match.

[0040] In this embodiment, the gear set 235 can be set to an enlarged size, which can increase the transmission ratio and improve the transmission efficiency during the transmission process of the gear set 235. The gear set 235 also includes a first gear 2351 meshed with the transmission gear 231, a second gear 2352 meshed with the first gear 2351, and a third gear 2353 meshed with the second gear 2352, and the third gear 2353 meshes with the rack 234. The second gear 2352 is set as a double gear, and the second gear 2352 includes a driven tooth 2354 meshed with the first gear 2351 and an active tooth 2355 meshed with the third gear 2353.

[0041] Among them, the module of the driven tooth 2354 is greater than the module of the driving tooth 2355, the module of the first gear 2351 is smaller than the module of the driven tooth 2354, and the module of the first gear 2351 is smaller than the module of the transmission gear 231, so that it can have a larger transmission ratio. When the movement distance of the rack 234 is certain, the door body 12 can have a larger opening angle.

[0042] In this embodiment, the pressing assembly 21 and the ejecting assembly 22 are both disposed in the box body 11. The ejecting assembly 22 can be disposed in the box body 11 and connected to the rack 234. The pressing assembly 21 can be disposed on the side wall of the box body 11 to facilitate the user to apply force to push the pressing assembly 21. Of course, in some embodiments, the force borne by the pressing assembly 21 can also be applied by other driving members. For example, the user can control the driving member to work on the control panel so that the force is applied to the pressing assembly 21.

[0043] like Figure 7 and Figure 8 As shown, the pressing assembly 21 has a pressing portion 211 for receiving the force, and the ejecting assembly 22 has a push rod 224 that moves relative to the box body 11, and the movement stroke of the pressing portion 211 is smaller than the movement stroke of the push rod 224. The push rod 224 can be connected to the rack 234, and the push rod 224 can push the rack 234 to move relative to the box body 11.

[0044] In this embodiment, the ejection assembly 22 includes an ejection seat 221 defining an ejection cavity 222, a transmission member 223 disposed in the ejection cavity 222, and the transmission member 223 is connected to the ejector rod 224. The pressing assembly 21 includes a pressing seat 212 defining a pressing cavity 213, an actuating member 214 disposed in the pressing cavity 213, and the actuating member 214 is connected to the pressing portion 211. Fluid can be stored in the ejection cavity 222, the pressing cavity 213, and the fluid pipeline 28.

[0045] When the pressing part 211 is subjected to a force, the pressing part 211 can drive the actuator 214 to move, so that the fluid in the pressing chamber 213 flows to the ejection chamber 222 through the fluid pipeline 28, and then the fluid can push the transmission part 223 to move, so that the transmission part 223 drives the ejector rod 224 to move, and the ejector rod 224 pushes the rack 234 to move, thereby realizing the opening of the door body 12.

[0046] Optionally, the pressing portion 211 may be configured as a plate-like structure, and the area of ​​the plate-like structure may be configured as required, as long as the user's comfort when pressing can be improved.

[0047] Furthermore, the ejection assembly 22 and the pressing assembly 21 may adopt a hydraulic cylinder or a cylinder structure. At least one of the actuating member 214 and the transmission member 223 is configured as a piston 26, and the piston 26 is movably disposed in the ejection chamber 222 or the pressing chamber 213. The ejection seat 221 is provided with a fluid inlet end 2211 for fluid to enter or flow out of the ejection chamber 222, and a push rod outlet 2212 for the push rod 224 to slide; the pressing seat 212 is provided with a fluid inlet end 2121 for fluid to enter or flow out of the pressing chamber 213, and a pressing opening 2122 for the pressing portion 211 to slide.

[0048] One end of the fluid pipeline 28 can be connected to the fluid inlet end 2211, and the other end of the fluid pipeline 28 can be connected to the fluid inlet end 2121. A spring 281 is also provided at the connection between the fluid pipeline 28 and the fluid inlet end 2211, 2121, and the spring 281 can be wound around the outside of the fluid pipeline 28 to strengthen the connection between the fluid pipeline 28 and the fluid inlet end 2121, 2211, and prevent the fluid from leaking from the fluid inlet end 2121, 2211.

[0049] In this embodiment, the action member and the transmission member 223 can both be configured as a piston 26. For the convenience of description, the piston 26 in the ejection chamber 222 can be an ejection piston 2231, and the piston 26 in the pressing chamber 213 can be a pressing piston 2141. The action area of ​​the pressing piston 2141 is larger than the action area of ​​the ejection piston 2231, so as to ensure that the movement stroke of the pressing portion 211 is smaller than the movement stroke of the ejector rod 224, and at the same time, the door body 12 can be opened with a relatively small action force.

[0050] In this embodiment, the ejector assembly 22 can be arranged at the top of the box body 11. The door opening device 20 also includes a box body 25, in which a receiving cavity is arranged, and the ejector assembly 22 and the gear transmission mechanism 23 can be arranged in the box body 25, which can ensure the neatness of the appearance of the refrigeration appliance 100 and improve the aesthetic appearance of the refrigeration appliance 100.

[0051] During the opening process of the door body 12, the user presses the pressing part 211, and the pressing part 211 pushes the pressing piston 2141 to move, and the ejection piston 2231 is pushed to move by the fluid, and the ejection piston 2231 drives the ejector rod 224 to move, and the ejector rod 224 drives the rack 234 to move and realize the opening of the door body 12 through the gear transmission mechanism 23. During the closing process of the door body 12, when the door body 12 moves to the first angle, the first stopper 2321 abuts against the second stopper 2322 to restore the ejection assembly 22 and the pressing assembly 21 to the initial position through the gear transmission mechanism 23, so as to facilitate the next opening of the door body 12.

[0052] like Fig. 9 As shown, in another embodiment of the present invention, at least one of the transmission member 223 and the actuating member 214 is configured as a bellows 27, the bellows 27 is disposed in the ejection cavity 222 or the pressing cavity 213, and the cavity in the bellows 27 is connected to the fluid pipeline 28 to allow the fluid to flow into or out of the bellows 27. Fig. 9 The figure shows the internal schematic diagram of the ejection assembly 22 provided in this embodiment. The internal schematic diagram of the pressing assembly 21 is similar to the internal schematic diagram of the ejection assembly 22 .

[0053] Furthermore, the bellows 27 can be configured as a rubber part. The bellows 27 is elastic and can be deformed under the action of fluid or force to drive the pressing part 211 and the ejector 224 to move. In some embodiments, the bellows 27 can also be configured as a plastic part, which can only realize the transmission between the pressing component 21 and the ejecting component 22.

[0054] Furthermore, the ejector rod 224 may also be configured as a plastic part, so that the ejector rod 224 has a high working strength and hardness, meeting the working requirements of the ejection assembly 22. Optionally, the telescopic bag 27 and the ejector rod 224 may be configured as an integral part.

[0055] In this embodiment, the transmission member 223 and the actuating member 214 may both be configured as a telescopic bag 27. For the convenience of description, the telescopic bag 27 in the ejection cavity 222 may be an ejection bag, and the telescopic bag 27 in the pressing cavity 213 may be a pressing bag. When the outer diameter of the ejection bag is the same as the inner diameter of the ejection cavity 222, and the outer diameter of the pressing bag is the same as the inner diameter of the pressing cavity 213, the effective area of ​​the ejection bag may be understood as the cross-sectional area of ​​the ejection cavity 222, and the effective area of ​​the pressing bag may be understood as the cross-sectional area of ​​the pressing cavity 213.

[0056] In summary, the beneficial effects of the present invention are as follows: during the use of the above-mentioned refrigeration appliance 100, when the pressing component 21 is subjected to a force, the fluid in the pressing component 21 flows to the ejection component 22 through the fluid pipeline 28 to push the ejector rod 224 to move, and the ejector rod 224 drives the gear transmission mechanism 23 to move, and drives the door body 12 to rotate relative to the box body 11 through the meshing portion 121, which can increase the opening angle of the door body 12 when the ejector rod 224 moves a certain distance, thereby helping to improve the user's comfort.

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.
