Present invention also offers a kind of refrigerator, in this refrigerator, be provided with above-mentioned vibration and noise reducing device, effectively reduce the noise that in refrigerator, compressor operating produces.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 provides by the embodiment of the present invention structural representation of vibration and noise reducing device;
Fig. 2 is the plan view of Fig. 1.
Embodiment
The embodiment of the invention discloses a kind of vibration and noise reducing device, to reduce because compressor operating produces noise.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technological scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Please refer to Fig. 1 and Fig. 2, the vibration and noise reducing device that the embodiment of the present invention provides comprises housing 1 and buffer solution 2.
Inner chamber 11 is provided with in housing 1.
Buffer solution 2 is filled among inner chamber 11, and its volume is less than the volume of inner chamber 11.
The vibration and noise reducing device that the present embodiment provides is arranged on the top of vibration source, namely utilizes fastening piece that housing 1 is fixed on the top of compressor 3.Operate at compressor 3, when producing vibration, the vibrated generation motion of the buffer solution 2 in inner chamber 11.In the process, on the one hand, buffer solution 2 is provided with flowing kinetic energy; Meanwhile, all heat-dissipating because of relative movement between buffer solution 2 interior molecules, between buffer solution 2 and housing 1 surface, is converted into energy in device by portion of energy.Therefore, the vibrational energy of compressor is converted into kinetic energy and interior energy by the vibration and noise reducing device that the present embodiment provides, thus reduces compressor and the vibration of taking over that is connected with compressor, achieves the object reduced because of compressor operating generation noise.
In the vibration and noise reducing device that above-described embodiment provides, housing 1 both can be the container of single cylindrical body, cuboid or fillet cuboid profile, also can for the combined shell be made up of multiple subshell.
