[ detailed description of the invention ]
As shown in fig. 1, the refrigeration device 100 includes a heat-insulated main body 101, and the main body 101 includes a storage chamber (not shown). The refrigeration appliance 100 includes a door 1 rotatably disposed in front of a main body 101 with respect to the main body 101.
The refrigeration appliance 100 comprises a hinge assembly 2 for connecting the door 1. In one embodiment, the door 1 serves to close the storage chamber inside the main body 101, and the door 1 is rotatably connected to the main body 101 by a hinge assembly 2.
As shown in fig. 1 and 3, the hinge assembly 2 includes a hinge plate 3, a hinge part 4 fixed to the hinge plate 3, and a fixing part 5 to fix the hinge part 4 to the hinge plate 3.
In the embodiment in which the door 1 is rotatably coupled to the main body 101, one end of the hinge plate 3 is fixed to the main body 101. In an alternative embodiment, for example, when the door 1 is rotatably connected to another door (not shown) located in front of the main body 101, one end of the hinge plate 3 may be fixed to the other door so that the door 1 may move along with the movement of the other door.
The hinge assembly 2 may be connected to the bottom of the door 1. The hinge plate 3 may be made of metal to have sufficient strength to support the weight of the door 1. The hinge plate 3 may be substantially plate-shaped.
The hinge plate 3 may have a plurality of fixing holes 31 for fixing the main body 101 or another door. The screw 9 passes through the fixing hole 31 to fix the hinge plate 3 to the bottom 102 of the main body 101 or the bottom of another door.
The hinge portion 4 is fixed to the other end of the hinge plate 3 to be hinge-coupled with the door 1. The hinge part 4 may include a hinge shaft 41 hinge-coupled with the door 1. In one embodiment, the hinge shaft 41 may have a shaft hole to receive a shaft portion protruding from a lower portion of the door 1, the shaft portion of the door rotating within the hinge shaft 41. In another embodiment, the hinge shaft 41 extends into a shaft hole located in the door 1. Thereby, the door 1 can be rotated around the hinge portion 4 fixed to the hinge plate 3.
As shown in fig. 1 and 2, the hinge portion 4 may include a door movement fitting portion 42 to be fitted with a door closer 6 fixed to the bottom of the door 1. The door motion-fitting portion 42 is connected to a lower end of the hinge shaft 41. The door closer 6 is adapted to apply a force perpendicular to the axial direction of the fixing piece 5 to the hinge portion 4. The door closer 6 may have a generally G-shape with a resilient wall 61 that abuts the door motion engaging portion 42.
The bottom of the door 1 may have a stop 8 to define the maximum opening angle of the door 1. The stop 8 may be fixed with the door closer 6.
In one embodiment, the hinge shaft 41 and the door motion fitting 42 are integrally formed. The hinge portion 4 may be made of metal.
The door motion coupling part 42 may include a first coupling part 421. When the end of the elastic wall 61 of the door closer 6 passes the highest point 4211 of the first matching part 421 along the outer circumference of the first matching part 421 during the door closing process, the direction of the thrust applied to the door movement matching part 42 by the door closer 6 is changed, and the door 1 is forced to be automatically closed. During the opening process, when the door closer 6 passes the highest point 4211, the direction of the thrust force applied by the door closer 6 to the door movement fitting portion 42 changes again.
The door motion mating portion 42 may also include a second mating portion 422 located on an opposite side of the first mating portion 421. When the door 1 is closed, the stopping portion 8 fixed to the bottom of the door 1 is engaged with the second engaging portion 422 when the door 1 is opened to a certain angle, so that it is possible to ensure that the door 1 cannot be moved further in the opening direction when it is opened to the maximum angle.
The hinge portion 4 is fixed to the hinge plate 3 by a fixing member 5. In one embodiment, the fixing member 5 is screwed through the hinge plate 3 and the hinge part 4. Specifically, the fixing member 5 may be screw-coupled through the mounting hole 32 and the coupling hole 420 at the door motion-fitting portion 42. The fixing member 5 may be a screw or a bolt. As shown in fig. 4, the mounting hole 32 and the fixing member 5 have a slight clearance therebetween to facilitate the fixing member 5 passing through the mounting hole 32.
In other embodiments, the fixing member 5 may be a fixing pin passing through the hinge plate 3 and the door motion-fitting portion 42.
As described above, at the moment when the door closer 6 passes the highest point 4211 of the first engagement portion 421, the direction of the thrust of the door closer 6 to the door movement engagement portion 42 is changed. If the fixing member 5 is not fixed tightly enough, the door motion-fitting portion 42 may be instantaneously moved, causing noise generated when the inner wall of the mounting hole 32 of the hinge plate 3 hits the fixing member 5.
To solve this problem, a positioning mechanism 7 for preventing the hinge portion 4 from rotating relative to the hinge plate 3 is provided between the hinge portion 4 and the hinge plate 3. The positioning mechanism 7 and the fixing piece are arranged at intervals.
In one embodiment, the positioning mechanism 7 is located directly below the hinge axis 41, and the mount 5 is offset from the hinge axis 41 in an axial direction X along the hinge axis 4.
In one embodiment, the positioning mechanism 7 may be provided to the insertion portion 43 of the hinge portion 4 and to the positioning hole 33 of the hinge plate 3. The positioning hole 33 and the insertion portion 43 have a fitting structure. The positioning hole 33 and the insertion portion 43 have a non-circular cross section so that the hinge portion 4 can be prevented from rotating relative to the hinge plate 3 after the insertion portion 43 is inserted into the positioning hole 33. Therefore, at the moment when the door closer 6 passes the highest point 4211 of the first engagement portion 421, the direction of the thrust applied to the door motion engagement portion 42 by the door closer 6 is changed, and the hinge portion 4 tends to rotate relative to the hinge plate 3, and since the large insertion portion 43 of the positioning mechanism 7 and the positioning hole 33 have a structure for preventing the relative rotation therebetween, the hinge plate 3 and the hinge portion 4 do not rotate during the engagement of the door closer 6 and the hinge portion 4, and therefore, the possibility of noise generation due to the collision of the mounting hole 32 and the fixing member 5 is reduced. This is advantageous for improving the user-friendliness of the refrigeration appliance 100.
In an alternative embodiment, the insertion portion 43 may also protrude upward from the hinge plate 3, and the positioning hole 33 is provided in the hinge portion 4.
In one embodiment, the positioning aperture 33 includes at least one flat inner wall 331. The positioning aperture 33 may include a pair of oppositely disposed flat inner walls 331. The insertion portion 33 having a cross section corresponding to the positioning hole 33 includes an outer wall adapted to the inner wall 331.
An interference fit may be provided between the insert 43 and the locating hole 33 to further reduce the likelihood of relative movement between the hinge portion and the hinge plate. In one embodiment, the outer circumferential surface of the insertion portion 43 may have a plurality of ribs 431 spaced apart to achieve an interference fit after the insertion portion 43 is inserted into the positioning hole 33.
