Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following instance for illustration of the present invention, but is not used for limiting the scope of the invention.
In describing the invention, it should be noted that, term " on ", D score, "left", "right", " in " etc. instruction orientation or position relationship be based on orientation shown in the drawings or position relationship, only the present invention for convenience of description and simplified characterization, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as limitation of the present invention.
In describing the invention, it should be noted that, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should be interpreted broadly, and such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be mechanical connection, also can be electrical connection; Can be directly be connected, also indirectly can be connected by intermediary, can be the connection of two element internals.For the ordinary skill in the art, concrete condition above-mentioned term concrete meaning in the present invention can be understood.
In addition, in describing the invention, except as otherwise noted, the implication of " multiple ", " many ", " many groups " is two or more.
With reference to the accompanying drawings 1 and 2, describe the air duct board of the refrigerator of the embodiment of the present invention in detail, it comprises outer panel 1, interior plate 2 and coaming plate 3, outer panel 1 is positioned opposite with interior plate 2, coaming plate 3 is connected with outer panel 1 and interior plate 2 respectively, coaming plate 3, outer panel 1 and interior plate 2 limit sound absorption chamber 4 jointly, and interior plate 2 is interval with multiple sound-absorbing hole 21 be communicated with sound absorption chamber 4.It should be noted that, in use, interior plate 2 is towards the inner side in air channel, and namely air-flow is when duct flows, the internal face of airflow passes interior plate 2 for the air duct board of refrigerator of the present invention, and wherein, " internal face " refers to towards the one side in air channel here.
In the present invention, arrange sound-absorbing hole 21 at interior plate 2, sound-absorbing hole is all communicated with sound absorption chamber 4, is communicated with sound absorption chamber 4, forms the Helmholtz resonator of many parallel connections because sound-absorbing hole 21 is all corresponding, forms a good Absorption System.Compared with prior art, effectively improve the acoustically effective of air duct board, reduce the noise of refrigerator air duct, promote the quiet quality of refrigerator.Particularly when incident sound wave frequency is consistent with the frequency of Absorption System, just evoke resonance.Of reciprocating vibration at the sound-absorbing hole 21 aperture place air column of interior plate 2, speed, amplitude reach maximum, and friction is also maximum with damping, and now acoustic energy is transformed into heat energy maximum, namely sound energy consumption is maximum.
Further, the thickness of interior plate 2 is preferably 2 ~ 8mm.The shape of sound-absorbing hole 21 can circular port, polygonal hole, irregular shape hole etc., and the shape of multiple sound-absorbing hole 21 can be identical, also can be incomplete same.Through experimental verification, the employing circular port that acoustically effective is best.In the present embodiment, sound-absorbing hole 21 is circular port.Preferably, the diameter of circular port is 2 ~ 5mm.Through experimental verification, when the diameter of circular port is 2 ~ 5mm, acoustically effective is preferentially when the diameter of circular port is less than 2mm or is greater than the situation of 5mm.Particularly when the thickness of interior plate 2 is 4mm, and when the diameter of circular port is 4mm, acoustically effective is best.
Preferably, interior plate 2 adopts composite plate to make.Through experimental verification, the interior plate 2 adopting composite plate to make has better acoustically effective.
Preferably, the gross area of sound-absorbing hole 21 and the area ratio of interior plate 2 are 10 ~ 30%.Area ratio is punching rate, and through experimental verification when punching rate is 10 ~ 30% time, acoustically effective is better than punching rate and is less than 10% or be greater than 30%.
Under entering, sound absorption is filled with sound-absorbing material in chamber 4.Filling sucting sound material in sound absorption chamber 4, effectively can improve acoustically effective.Sound-absorbing material preferably adopts foamed plastics, UF foamed plastics, industrial felt or foam glass, avoids sound-absorbing material to absorb condensate water, stops the problem that air duct board freezes.
Preferably, coaming plate 3 adopts rubber to make.Employing rubber is made, and improves the acoustically effective in sound absorption chamber.
The present invention also provides a kind of refrigerator, comprising: casing, door body and air channel, have refrigeration compartment in casing; Door body is arranged on casing, is used to open or close refrigeration compartment; Air channel is located in casing, and air channel comprises the air duct board described in any one embodiment above-mentioned, and the interior plate of air duct board described in this is inside air channel.The concrete structure easy understand for those skilled in the art of refrigerator, is no longer described in detail in the present invention.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
