Description
[ technical field ]
The present invention relates to a refrigeration appliance, and more particularly to a refrigeration appliance such as a refrigerator, a wine chest, a freezer, and the like, having a door hinge assembly.
[ background art ]
It is known that the height of a door of a refrigeration appliance relative to the appliance body can be adjusted by means of a door hinge assembly having a height adjustment device. For example, publication CN201731720U discloses a refrigerator door height adjusting device including a hinge support and an adjusting member, an upper end of a hinge shaft fixed on the hinge support having gradually rising/falling adjusting teeth, the adjusting member being provided with insections at a section of the adjusting teeth facing the hinge shaft to engage with the adjusting teeth. When the adjusting piece is rotated, the adjusting piece rotates relative to the hinge shaft, the height of the adjusting piece relative to the refrigerator main body is changed, and then the height of the door body supported by the upper end of the adjusting piece is changed.
After the refrigerator is assembled, it is not easy for a worker to check information about the height of the refrigerator door.
[ summary of the invention ]
It is an object of the present invention to provide an improved refrigeration appliance having a door height adjustable hinge assembly.
The above object is achieved by the features of the independent claims. Preferred embodiments of the invention are the subject of the figures, the description and the dependent claims.
One aspect of the present invention relates to a refrigerator appliance including a main body, a rotatable door, and a hinge assembly connecting the door and the main body and adjustable in height, characterized in that the hinge assembly includes a visual indicator unit displaying information about the height of the hinge assembly.
Since the height information of the hinge assembly can be directly obtained by viewing the indicating unit, when the height of the door needs to be adjusted, a worker/after-sales service person can directly obtain information on the height of the door with respect to the main body, thereby making the adjustment of the hinge assembly easier. On the other hand, by viewing the information displayed by the indicator unit, it is possible for the hinge assembly to be adjusted to a uniform height position (e.g., a height position that facilitates transport of the refrigeration appliance) prior to packaging of the refrigeration appliance, thereby facilitating production and transport quality control of the refrigeration appliance.
In the present invention, the height of the hinge assembly refers to the distance between the support surface of the hinge assembly to be directly against the door and a reference surface immovable with respect to the main body. For example, since the hinge bracket is typically immovably fixed to the main body, when the hinge bracket is used as a reference plane, the height of the hinge assembly may be the distance of the hinge bracket to the support plane of the hinge assembly against the door.
The height of the hinge assembly may be adjusted by a step, for example the hinge assembly is adjusted by a step between a plurality of heights (e.g. three to five heights). It is also possible to adjust the height of the hinge assembly steplessly, for example the hinge assembly may comprise an adjustment with a thread or an adjustment with gear teeth to steplessly adjust the height of the door.
In one possible embodiment, the information about the height of the hinge assembly may include whether the hinge assembly is in a state of having a predetermined height. For example, the indicator unit may be arranged as an indicator portion which may indicate one or more heights. This is advantageous to ensure that the hinge assembly is adjusted to the same predetermined height when the refrigeration appliance is shipped, for example a height particularly suitable for transportation.
In one possible embodiment, the information about the height of the hinge assembly may include whether the height of the hinge assembly is at the extreme of its adjustable range. Such as whether the hinge assembly is at a minimum height or whether the hinge assembly is at a maximum height. Based on this, it is contemplated that the hinge assembly is in a lowermost or uppermost position when the refrigerator is shipped. This not only facilitates adjustment of the hinge assembly for subsequent servicing, but for some hinge assemblies, locating the hinge assembly at the lowest position also facilitates avoiding damage to the adjustment unit during transport.
In one possible embodiment, the indicator unit is located outside the door. Since the indication unit is exposed outside the door, rather than being received inside the door (e.g., in the hinge hole), the indication unit can be seen without taking additional measures (e.g., lifting the door to a predetermined height to expose the indication unit), thereby facilitating the operation of a worker or an after-sales service person.
In one possible embodiment, the hinge assembly may include a first member immovably fixed to the main body and an adjustment member rotatable with respect to the first member, and the indication unit includes a first indication portion on the first member and a second indication portion on the adjustment member, and information on a height of the hinge assembly is indicated by a relative position of the first indication portion and the second indication portion. By distributing the first indicator and the second indicator over the first part, which is fixed relative to the main body, and the adjuster, which is operated to rotate, respectively, the state of the hinge assembly can be determined directly and reliably. The first component may for example be a hinge bracket or a hinge shaft which is not movable relative to the body during height adjustment of the door.
In one possible embodiment, the first component is a hinge bracket attached to the main body. Since the hinge bracket is usually of a relatively large size, it is not only easy to provide the first indication on the hinge bracket, but also to identify itself and the first indication located on the hinge bracket.
In one possible embodiment, the hinge bracket includes a horizontal support portion, and the first index portion is located on an upper surface or a lower surface of the support portion. This is particularly advantageous for the arrangement and identification of the first marking portion.
In one possible embodiment, the adjustment member includes an adjustment groove, and the second indicator is disposed in association with the adjustment groove. Thereby facilitating the operator to quickly and directly obtain an indication of the indicating unit.
In one possible embodiment, the second index portion may be adjacent to one end of the adjustment groove and have a center plane coincident with a center plane of the adjustment groove. In an alternative embodiment, at least one end of the adjustment slot forms the second indicator.
In one possible embodiment, the hinge assembly has a minimum height when the second indicator points toward the first indicator or the first indicator points toward the second indicator. This is advantageous in that the door of the refrigerator can be set at a minimum height when leaving the factory and can be adjusted upwards as required when the door is lowered during use. In addition, the operator can conveniently determine the direction needing to be adjusted according to the indication of the marking unit. At least one of the first indicating portion and the first indicating portion may have an arrow shape to make the indicating function of the indicating unit more apparent.
In one possible embodiment, the adjusting unit includes a first adjusting portion and a second adjusting portion, the first adjusting portion and the second adjusting portion respectively include a plurality of bearing surfaces located at different heights, when the bearing surfaces of the first adjusting portion and the second adjusting portion are complementarily butted, the hinge assembly is at a minimum height, and the indicating unit is used for indicating whether the hinge assembly is at the minimum height. Since the first adjusting part and the second adjusting part can be mutually limited in the circumferential direction, the possibility of damage to the adjustable hinge assembly of the refrigeration appliance during transportation is reduced.
The construction of the present invention and other objects and advantages thereof will be more apparent from the following description of the preferred embodiments taken in conjunction with the accompanying drawings.

[ detailed description of the invention ]
Fig. 1 shows a partial perspective view of a refrigeration appliance 100 according to a preferred embodiment of the present invention. As shown in fig. 1, the refrigerator appliance 100 includes a main body 101 having a storage chamber and a pair of doors 102, 102' connected to the main body 101 to close or open the storage chamber. Doors 102, 102' are respectively hinged at left and right sides of the body 101 to open or close the corresponding storage compartments. The refrigeration appliance 100 may further comprise a drawer-type door 103 located at a lower portion of the main body 101.
The refrigeration appliance 100 includes a hinge assembly 1 connected between a lower end of each door 102, 102' and the main body 101. The hinge assembly 1 is provided to adjust the height of the corresponding door 102, 102' with respect to the main body 101.
Fig. 2 illustrates an exploded perspective view of the hinge assembly 1 according to a preferred embodiment of the present invention. Referring to fig. 2 in conjunction with fig. 1, the hinge assembly 1 includes a hinge frame 2 fixed to a main body 101, a hinge shaft 8 fixed to the hinge frame 2, and an adjusting member 3 rotatably connected to the hinge shaft 8 with respect to the hinge shaft 8. The adjusting member 3 is operated during the height adjustment of the door.
The hinge bracket 2 includes a mounting portion 21 fixed to the main body 101. The mounting portion 21 may be provided with a plurality of fixing holes 22 to allow suitable fasteners (not shown) to pass through the mounting portion to secure the hinge bracket to the main body 101. The fixing member may be a screw. In this embodiment, the mounting portion 21 is attached to the front surface of the main body 101. In an alternative embodiment, the hinge bracket may also be fixed to the lower surface of the main body, which is particularly suitable in the case where the lower wall of the storage compartment is formed by the bottom wall of the main body.
The hinge bracket 2 includes a support portion 23 extending forward from the mounting portion 21. The support 23 is substantially plate-shaped perpendicular to the front surface of the main body 101. The supporting portion 23 and the mounting portion 21 may be integrally formed.
The hinge assembly 1 comprises a hinge shaft 8 immovably fixed on the hinge frame 2. The hinge shaft 8 defines a rotation axis of the door 102, and is immovable with respect to the main body 101.
The hinge shaft 8 is fixed to the support 23 and extends vertically upward from the support 23. During the rotation of the door 102, the hinge shaft 8 is not movable relative to the support 23. In this embodiment, the hinge shaft 8 and the support 23 are integrally formed. In an alternative embodiment, the hinge shaft 8 and the support 23 may also be manufactured separately and then assembled together.
In this embodiment, the hinge shaft 8 is a hollow cylinder with a central hole 80. The central aperture 80 may penetrate the support 23.
The adjuster 3 includes a base 31 and a rod body 32 vertically extending downward from a lower end of the base 31. The base 31 and the rod 32 are solid cylinders of different diameters, so that the longitudinal section of the adjustment member 3 is substantially T-shaped. The diameter of the base 31 may be equal to the outer diameter of the hinge shaft 8 and the diameter of the rod 32 is slightly smaller than the smallest inner diameter of the hole 80.
The adjusting member 3 is rotatably installed on the door 102 or 102'. Specifically, the rod body 32 is received in the hole 80, and the lower end surface of the base 31 is seated on the upper end surface of the hinge shaft 8.
The adjusting member 3 may be formed with at least one adjusting groove 37 at a lower end surface thereof. An operator can insert an adjusting tool such as a screwdriver into the adjusting slot 37 from below the hinge bracket 2. The adjusting member 3 is rotated with respect to the hinge shaft 8 by inserting a corresponding tool into the adjusting groove 37 and rotating the adjusting member 3.
The lower end of the base 31 forms a first regulation part 33, and the hinge shaft 8 includes a second regulation part 82 in face-to-face contact with the first regulation part 33 in the vertical direction. The second regulation part 82 may be formed by an upper end portion of the hinge shaft 8, integrally formed with the hinge shaft 8.
The hinge assembly 1 includes a bushing 6 which is sleeved outside the adjusting member 3 and the hinge shaft 8 from the top down. The bushing 6 may be inserted within the door 102. The bushing 6 extends into an axial hole (not shown) at the bottom of the door 102 and is at least largely accommodated within the door 102.
In order to reduce friction between the top wall 60 of the bushing 6 and the top surface of the adjustment member 3, a gasket 7 may be provided between the top wall 60 of the bushing 6 and the top surface of the adjustment member 3.
As shown in fig. 2 and 3, the first regulation portion 33 includes a plurality of bearing surfaces. Specifically, a first support surface 34a, a second support surface 34b and a third support surface 34c are included at different heights. The first, second and third bearing surfaces 34a, 34b and 34c are stepped down as viewed from above, with a step formed between adjacent bearing surfaces 34a, 34b and 34 c.
In this embodiment, the first bearing surface 34a, the second bearing surface 34b and the third bearing surface 34c are parallel to the horizontal plane.
In order that the adjusting member 3 can be stably supported on the upper end surface of the hinge shaft 8, the bearing surfaces 34a, 34b, 34c located at different heights are respectively arranged in pairs, and each pair of the bearing surfaces 34a, 34b, 34c is symmetrically arranged with respect to the central axis of the rod body 32. Preferably, adjacent bearing surfaces 34a, 34b, 34c have the same height difference therebetween.
Correspondingly, the second adjusting part 82 also comprises a plurality of stepped-up horizontal fourth 8a, fifth 8b and sixth 8c bearing surfaces. The fourth bearing surface 8a, the fifth bearing surface 8b and the sixth bearing surface 8c are also provided in pairs, respectively.
The adjacent first, second, and third bearing surfaces 34a, 34b, and 34c are connected by a vertical first connecting surface 35. The adjacent fourth to sixth bearing surfaces 8a, 8b, 8c are also connected by a vertical second connecting surface 84.
When the adjusting member 3 rotates relative to the hinge shaft 8, the relative positions of the bearing surfaces of the first adjusting part 33 and the second adjusting part 82 are changed, so that the height of the adjusting member 3 relative to the main body 101, and thus the height of the door 102 supported by the adjusting member 3 relative to the main body 101, can be changed. At least one of the bearing surfaces 34a, 34b, 34c of the first adjustment part 33 seats on a corresponding bearing surface 82a, 82b, 82c of the second adjustment part 82.
The height of the hinge assembly 1 should be the distance between the support surface against the door 102 and a reference surface that is not movable relative to the body. The reference plane should be constant over the adjustable height of the hinge assembly 1. For example, when the upper surface of the support 23 is taken as a reference surface, the height of the hinge assembly 1 is embodied as a distance between the top surface of the bushing 6 and the upper surface of the support 23. It is obvious that the ground or the bottom surface of the body 101, for example, can also be used as a reference surface.
It will be appreciated that when other components of the hinge assembly 1, such as the adjuster or hinge axis, are directly against the door 102, then the height of the hinge assembly 1 should be calculated on the top surface of these components.
Fig. 3 illustrates an engaged state of the first and second adjusting portions 33 and 82 when the hinge assembly 1 has a minimum height. In this position, as shown in fig. 3, the bearing surfaces of the first and second adjustment parts 33, 82 abut like a complementary, with no spacing between the opposing bearing surfaces of the first and second adjustment parts 33, 82. Specifically, the first bearing surface 34a of the first regulation part 33 is supported by the sixth bearing surface 8c of the second regulation part 82, and accordingly, the second bearing surface 34b and the fifth bearing surface 8b are engaged, and the third bearing surface 34c and the fourth bearing surface 8a are engaged. Each first coupling face 35 and the corresponding second coupling face 84 are in circumferential abutment, preventing the rotation of the adjustment member 3.
In the position shown in fig. 4, the hinge assembly 1 is adjusted to have an intermediate height, the second bearing surface 34b is in abutment with the sixth bearing surface 8c, the third bearing surface 34c is in abutment with the fifth bearing surface 8b, and the first bearing surface 34a is spaced from the fourth bearing surface 8 a.
Similarly, when the hinge assembly 1 has the maximum height, the relationship between the adjuster 3 and the hinge shaft 8 is as shown in fig. 5. In this position, the third bearing surface 34c and the sixth bearing surface 8c abut, and the first bearing surface 34a and the second bearing surface 34b are spaced apart from the fifth bearing surface 8b and the fourth bearing surface 8a, respectively.
Referring to fig. 6, the hinge assembly 1 includes a marking unit 5 displaying information about the height of the hinge assembly 1. In this embodiment, the indicating unit 5 may indicate information whether the hinge assembly 1 is in a position having a minimum height.
The indicating unit 5 is located outside the door 102. In this embodiment, the indicating unit 5 includes a pair of first indicating portions 51 on the hinge bracket 2 and a pair of second indicating portions 52 on the adjuster 3, and information on the height of the hinge assembly 1 is indicated by the relative positions of the first and second indicating portions 51 and 52.
It will be understood that it is also possible that the hinge bracket 2 and the adjustment member 3 are provided with only one first indicator and one second indicator, respectively, for indicating a height.
The first indicating portion 51 is located on the lower surface 230 of the horizontal support portion 23. The second indicator 52 is located at the bottom of the adjustment member 3 and is arranged in association with the adjustment groove 37. In this embodiment, each second index 52 is adjacent a respective end of the adjustment slot 37 at 37 and has a central plane coincident with the central plane of the adjustment slot 37.
In this embodiment, the second indicator portion 52 is arrow-shaped. When the second indicator 52 is directed to the first indicator 51, the hinge assembly 1 has a minimum height.
In this embodiment, the first and second indications 51, 52 are formed by a configuration of the hinge bracket 2 and the adjustment element 3, respectively, which has an indicating effect on its own, for example a projection or a recess on the hinge bracket 2 and the adjustment element 3, respectively. In an alternative embodiment, the first and second indicators 51, 52 may be formed by patterns, letters, and/or logos, etc. attached to the adjustment member 3 by means of gluing or printing.
The various embodiments of the individual components described in connection with fig. 1 to 6 may be combined with each other in any given way to achieve the advantages of the invention. In addition, the present invention is not limited to the illustrated embodiments, and other means than those shown may be generally used as long as the same effects are obtained.
