The embodiment of the utility model provides an in the refrigerator, first damping pad 61 is also not only in the mode of setting on wind channel wall 3, for example can be following mode of setting: as shown in fig. 7, the air duct wall 3 includes a wall surface 31 and a first connecting seat 32 disposed on the wall surface 31, the first connecting seat 32 has a fixing slot 321, and as shown in fig. 5, a first damping pad 61 is disposed in the fixing slot 321 in an interference manner and separates the connecting pin 41 from the first connecting seat 32. As shown in fig. 10, the first damper pad 61 may be directly connected to the wall surface 31 of the air duct wall 3 by a fastener (e.g., a screw). Compared with the embodiment that the first damping pad 61 is directly connected with the wall surface 31 of the air duct wall 3 through the fastener, the embodiment that the first damping pad 61 is arranged in the fixed clamping groove 321 of the first connecting seat 32 in an interference manner has the advantages that the first damping pad 61 is more convenient and quicker to install, and the installation time of the fastener is saved; further, the first damper pad 61 is provided on the first connection seat 32, so that the wall surface 31 of the air duct wall 3 is not easily damaged.

For example, as shown in fig. 7, the fixing clip groove 321 may be opened on a side surface a of the first connecting seat 32 (i.e., a surface of the first connecting seat 32 extending along the height direction Y thereof), as shown in fig. 5, an installation groove 611 is opened on a side surface of the first damping pad 61, and an orientation of the installation groove 611 is the same as an orientation of the fixing clip groove 321, and the connecting pin 41 extends into the installation groove 611 and is connected to the first damping pad 61 through the first connecting structure 7. In addition, as shown in fig. 11, the fixing slot 321 may also be opened on an end surface of the first connecting seat 32 away from the wall surface 31, and the first vibration damping pad 61 with a dovetail-shaped cross section of the fixing slot 321 extends into the fixing slot 321 and is in interference fit with the fixing slot 321. The connecting pin 41 is disposed on the end surface of the first damping pad 61 far away from the fixing slot 321, and is connected with the first damping pad 61 through the first clamping structure 7. Compare fixed slot 321 and offer on the terminal surface of first connecting seat 32, when fixed slot 321 offered on the side of first connecting seat 32, first damping pad 61 can be fixed better to first connecting seat 32, first damping pad 61 sets up in fixed slot 321, the cell wall of fixed slot 321 can wrap up first damping pad 61, the vibration range that connecting pin 41 drove first damping pad 61 is connected in the better restriction, thereby be favorable to weakening the vibration transmission between connecting pin 41 and the first connecting seat 32.

Through setting up first dodge mouthful 6221, when fan body 42 stretches into spacing space 623, connect foot 41 just can stretch out from first dodge mouthful 6221 and first damping pad 61 joint like this, not only made things convenient for fan 4 to connect foot 41 and first damping pad 61 joint, connect foot 41 just need not to connect the foot 41 and just need not to stagger the setting with lateral wall 622 along the thickness direction of first damping pad 61 in addition to make the mounted position of connecting foot 41 on fan body 42 unrestricted.

As shown in fig. 13, when the side surface of the first vibration damping pad 61 is provided with the mounting groove 611, the notch of the mounting groove 611 faces the first escape opening 6221.

In order to facilitate the harness of the fan 4 to penetrate out of the limiting space 623 of the second vibration damping pad 62 and fix the harness, as shown in fig. 12 and 13, a second avoiding opening 6222 is further formed in the side wall 622, a harness clamping groove 6211 is formed in the position, corresponding to the second avoiding opening 6222, of the bottom wall 621 in the circumferential direction of the bottom wall 621, and the harness of the fan 4 penetrates out of the second avoiding opening 6222 and is clamped with the harness clamping groove 6211. Through setting up the second and dodging mouth 6222, after fan 4 finishes with first damping pad 61, second damping pad 62 installation, the pencil of fan 4 just can be worn out and with pencil draw-in groove 6211 joint from the second dodge mouth 6222, just so prevents that the pencil of fan 4 from removing to just can avoid appearing the pencil and remove the problem of the unusual noise that causes of scraping fan 4's flabellum.

In the vibration damping device 6, the second vibration damping pad 62 may be made of a rubber material, or may be made of other vibration damping materials, and is not particularly limited herein. The second damping pad 62 may be integrally formed with the first damping pad 61 (as shown in fig. 13), or may be designed separately, which is not limited herein.
