Description

A kind of refrigerator

Technical Field

The invention relates to the technical field of storage equipment, in particular to a refrigerator.

Background

A refrigerator, which is a storage device maintaining a low temperature, prevents food or other articles from being spoiled by maintaining the food or other articles in a cold state at a constant low temperature, and is an indispensable storage device in daily life of people. In order to improve the preservation performance of the refrigerator, the refrigerator with the vacuum pump mounted inside is adopted in the prior art, the storage chamber of the refrigerator is vacuumized through the vacuum pump, so that a vacuum space is formed in the storage chamber, and the stored food cannot be rotted due to the fact that air is rare and microorganisms do not have survival conditions under the vacuum condition, so that a good food preservation effect can be achieved. However, when the vacuum pump is operated, severe vibration is generated, which causes loud noise and affects the rest of the user.

In view of the above problems, the prior art has provided a vacuum pump capable of reducing vibration and noise for a refrigerator, for example, chinese utility model patent with application number 201420177671.0 entitled vibration and noise reduction vacuum pump for a refrigerator, as shown in fig. 1, which comprises a pump body 1, a driving motor 2 and a first sealing shell, the pump body is externally provided with a second sealing shell 11, the driving motor 2 is provided with a vibration reduction fixing ring 3, the first sealing shell comprises a first sealing shell upper cover 5 and a first sealing shell lower cover 4, the pump body 1 provided with the second sealing shell 11 and the driving motor 2 provided with the vibration reduction fixing ring 3 are integrally installed in the first sealing shell lower cover 4, then the first sealing shell upper cover 5 is covered with the first sealing shell lower cover 4, at this time, the first sealing shell seals the driving motor 2 and the pump body 1, when the pump body 1 is in operation, vibration is absorbed by the vibration reduction fixing ring 3 and the second sealing shell 11, and the first sealed shell can weaken the transmission of noise, thereby reducing the noise; then, still be provided with the one deck third sealed shell outside first sealed shell, the third sealed shell includes third sealed shell upper cover 8 and third sealed shell lower cover 7, and first sealed shell is packed into in the third sealed shell, is provided with spacing post 6 of damping between the bottom of third sealed shell lower cover 7 and the bottom surface of first sealed shell lower cover 4, and at the pump body 1 during operation, through spacing post 6 of damping cushion vibration once more, play the damping effect to form double-deck damping effect.

However, the vacuum pump is provided with three layers of sealed casings outside the pump body 1, and a vibration damping structure is arranged between every two layers of sealed casings, so that the overall volume is large, when the vacuum pump is installed in a storage chamber of a refrigerator, the vacuum pump occupies a large space inside the storage chamber, so that the effective use space in the storage chamber is reduced, and when the pump body 1 vibrates during operation, the first sealed casing is driven to vibrate together, and because the vibration damping limiting column 6 is arranged between the bottom surface of the first sealed casing lower cover 4 and the bottom of the third sealed casing lower cover 7, when the first sealed casing vibrates, the vibration damping limiting column 6 can only absorb the vibration of the first sealed casing in the direction close to the bottom of the third sealed casing, and can not absorb the vibration of the first sealed casing in other directions, that is, the outer wall of the first sealed casing except the bottom surface can not collide with the inner wall of the third sealed casing except the bottom surface, resulting in a non-ideal damping effect.
