DETAILED DESCRIPTION

[0016] To make the above objectives, features, and advantages of the present utility model clearer and more comprehensible, specific embodiments of the present utility model are described below in detail with reference to the accompanying drawings.

[0017] Referring to FIG. 1 and FIG. 2, the present utility model provides a refrigerator 1 and a fan assembly 10 disposed in the refrigerator 1. FIG. 2 is a diagram of an inner structure of the refrigerator 1 in FIG. 1 in a right view direction. The refrigerator 1 includes a body 3 having one or more storage rooms 2, and the fan assembly 10 is disposed in the storage room 2, and is generally disposed at one side that is of the storage room 2 and that is far away from a door of the refrigerator, that is, at an inner side of the storage room 2.

[0018] Referring to FIG. 3 and FIG. 4, the fan assembly 10 includes a mounting base 20 and a fan 30 that is fastened to the mounting base 20. The fan assembly 10 is fastened to the body 3 by using the mounting base 20. The mounting base 20 includes a housing 21 accommodating the fan 30, and a reinforcement member 22 that fastens the housing 21 to a to-be-mounted structure; the housing 21 is provided with a first connecting member 211 and the reinforcement member 22 is provided with a second connecting member 221 that matches and that is connected to the first connecting member 211; and the first connecting member 211 is indirectly connected to the second connecting member 221 by using a vibration reduction element 40.

[0019] An advantage of the solution is that the housing of the fan and the body of the refrigerator are indirectly flexibly connected by using the vibration reduction element without being directly rigidly connected any longer. Therefore, vibration energy of the housing of the fan is absorbed by the vibration reduction element without being directly transferred to the body of the refrigerator, thereby greatly reducing noise generated by high-speed operation of the fan.

[0020] In the fan assembly 10, a function of the fan 30 is accelerating air flowing in the storage room 2, so that temperature distribution within the storage room 2 is more uniform. Generally, an air exhaust vent of the fan 30 is close to an inner wall of the storage room 2, and an air intake vent faces a relatively large space, so that air in the storage room 2 flows towards the air intake vent, enters the fan 30 from the air intake vent, and flows out from the air exhaust vent after being mixed by the fan 30, thereby achieving a uniform air temperature. Therefore, it can be understood that when a user opens the door, one side of the air exhaust vent of the fan 30 is located at a relatively concealed location and is not easily seen.

[0021] It can be learned from the embodiment shown in FIG. 2 that, the fan assembly 10 is located at the inner side of the storage room 2, and an air intake vent 10a of the fan 30 is located at one side that is of the door and that faces the refrigerator 1, and an air exhaust vent 10b is located at one side that is of the door and that is away from the refrigerator 1. In this way, when a user opens the door, the user can see the air intake vent 10a of the fan 30, but cannot see the air exhaust vent 10b of the fan 30.

[0022] As shown in FIG. 3 and FIG. 4, the mounting base 20 includes the housing 21 accommodating the fan 30, and the reinforcement member 22 that fastens the housing 21 to the to-be-mounted structure. The reinforcement member 22 includes a body plate 222 and the second connecting member 221. In this embodiment, the second connecting member 221 includes a fastener 221a and a gasket 221b that may be connected together. In a process of mounting or dismounting the mounting base 20, the fastener 221a and the gasket 221b may be separated from each other.

[0023] The fastener 221a extends towards one side that is of the body plate 222 and that faces the housing 1. The fastener 221a and a plate surface of the body plate 222 are intersected. The plate surface of the body plate 222 has a first surface facing the housing 21, and a second surface away from the housing 21. The gasket 221 b has an end portion that is close to the body plate 222 and an end portion that is far away from the body plate 222. Particularly, the radial width of the end portion that is of the gasket 221b and that is close to the body plate 222 is greater than that of the end portion that is far away from the body plate 222. The end portion that is of the gasket 221b and that is close to the body plate 222 is connected to the fastener 221a. The end portion that is of the gasket 221b and that is far away from the body plate 222 passes through the vibration reduction element 40, that is, the vibration reduction element 40 is sleeved on the end portion that is of the gasket 221b and that is far away from the body plate 222. Preferably, the vibration reduction element 40 is made of a silica gel material and has a good vibration isolation effect. The first connecting member 211 of the housing 21 is engaged with the vibration reduction element 40. In this way, the first connecting member 211 is indirectly connected to the second connecting member 221 by using the vibration reduction element 40, so that the housing of the fan and the body of the refrigerator are indirectly flexibly connected by using the vibration reduction element without being directly rigidly connected any longer. Therefore, vibration energy of the housing of the fan is absorbed by the vibration reduction element without being directly transferred to the body of the refrigerator, thereby greatly reducing noise generated by high-speed operation of the fan.

[0024] Both the fastener 221a and the gasket 221b are provided with through holes that extend along a length direction and that are communicated with each other, and a screw 50 is driven into the through hole, to better implement a fixed connection between the housing 21 and the reinforcement member 22. Preferably, the end portion that is of the gasket 221b and that is far away from the body plate 222 exceeds a preset length, for example, 2-3 millimeters, of an end portion that is of the vibration reduction element 40 and that is far away from the body plate 222. In this way, after the screw 50 is driven into the gasket 221b, a head of the screw 50 may be prevented from pressing against the vibration reduction element 40, thereby ensuring that vibration isolation performance of the vibration reduction element 40 is not affected. Preferably, a gasket 51 is further disposed on the end portion that is of the vibration reduction element 40 and that is far away from the body plate 222, to further prevent the head of the screw 50 from excessively pressing against the vibration reduction element 40.

[0025] FIG. 5 is a schematic exploded view of a fan assembly according to a second embodiment of the present utility model. A difference between this embodiment and the first embodiment at least lies in that the second connecting member of the reinforcement member 22 is formed by extending the fastener 221a' through the vibration reduction element 40 to the side that is of the body plate 222 and that faces the housing 1. That is, in this embodiment, the second connecting member is basically formed by extending the fastener 221a', so that disposition of the gasket 221b is omitted. Preferably, the end portion that is of the fastener 221a' and that is far away from the body plate 222 exceeds the preset length, for example, 2-3 millimeters, of the end portion that is of the vibration reduction element 40 and that is far away from the body plate 222. In this way, after the screw 50 is driven into the fastener 221a', the head of the screw 50 may be prevented from excessively pressing against the vibration reduction element 40, thereby ensuring that vibration isolation performance of the vibration reduction element 40 is not affected.

[0026] FIG. 6 is a schematic exploded view of a fan assembly according to a third embodiment of the present utility model. A difference between this embodiment and the first embodiment at least lies in that the second connecting member of the reinforcement member 22 is basically directly formed by using the fastener 221a in FIG. 4, so that disposition of the gasket 221b is omitted. In addition, a screw 50' has a limiting step 52', and after the screw 50' directly passes through the vibration reduction element 40 and is driven into the through hole of the fastener 221a, the limiting step 52' of the screw 50' abuts against a hole edge 221c of the through hole of the fastener 221a, to implement a limitation, so that the screw 50' is prevented from further being driven into the through hole, and the head of the screw 50' may be prevented from excessively pressing against the vibration reduction element 40, thereby ensuring that vibration isolation performance of the vibration reduction element 40 is not affected.

[0027] Although the present utility model has been disclosed above, the present utility model is not limited thereto. Any person skilled in the art can make various modifications and changes without departing from the spirit and the scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the scope defined by the appended claims.
