Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the invention, and
The embodiment being not all of.Based on the embodiment in the present invention, those of ordinary skill in the art are not doing
Go out all other embodiment obtained under the premise of creative work, belong to the scope of protection of the invention.
Fig. 1 is the rip cutting figure that refrigerating appliance casing is pass by from the side in the embodiment of the present invention.Such as Fig. 1 institutes
Show, refrigerating appliance casing 100 includes the storage compartment 101 for being used to store item to be cooled, in the storeroom
The inside back of room 101 sets air channel 10 and refrigeration chamber 50, and air channel 10 is connected with refrigeration chamber 50.System
Evaporator 51 is set in cold chamber 50 and the blower fan 52 of the top of evaporator 51 is arranged at.Evaporator 51 is used
The wind of refrigeration chamber 50 is flowed through in cooling, blower fan 52 is then to agitate wind in refrigeration chamber 50, the and of air channel 10
Circulated between the storage three of compartment 101.The specific cyclic process of wind is；The higher wind of temperature enters
Refrigeration chamber 50 is simultaneously cooled down by evaporator 51 and becomes the relatively low cold wind of temperature, under the agitating of blower fan 52,
Cold wind flows up into air channel 10, and is entered by being distributed in the air outlet 13 of the different zones of air channel 10
Enter to store compartment 101.Cold wind becomes the higher wind of temperature after storage compartment 101 takes away heat and but also returned not only
Refrigeration chamber 50 is returned to, so as to start next wind circulation again.Air channel 10 includes vertical connection connection respectively
First passage 11 and second channel 12.First passage 11 is directly connected with refrigeration chamber 50, to make by oneself
The cold wind of cold chamber 50 flows into first passage 11 directly up under the agitating of blower fan 52.13 points of air outlet
The different zones of the in the vertical direction of second channel 12 are not distributed in, and it is laggard that cold wind flows through first passage 11
Enter second channel 12, and storage compartment 101 is flowed into by each air outlet 13.
Fig. 2 is the rip cutting figure that refrigerating appliance casing is looked over from the back side in the embodiment of the present invention.It is logical first
The intersection in road 11 and refrigeration chamber 50 sets air inlet 53, and blower fan 52 is installed under air inlet 53
Side.The cold wind cooled down by evaporator 51 is agitated by blower fan 52 and directly enters first by air inlet 53
Passage 11.On cold wind flow direction straight up, the transverse width of first passage 11 is less and less,
The vertical section of especially first passage 11 is configured to approximate trapezoid shape, and such structure can be reduced positioned at wind
The ballast pressure of the first passage 11 of the top of machine 52, reduction blower fan 52 is loaded, so as to reach following two side
The noise reduction in face：On the one hand it is that the load of blower fan 52 diminishes, then its corresponding operating noise can also diminish,
Another aspect is that the ballast pressure in first passage 11 diminishes, then wind flows and produced in first passage 11
Raw fluid noise can also diminish., can be first in order to reach the effect of preferably reduction fluid noise
First silencing means 21 is set in passage 11, produced portion is flowed in first passage 11 to absorb wind
Shunting body noise, first silencing means 21 is preferably configured to be bloop, particularly takes shape in
Round blind hole on the internal face of first passage 11, such first passage 11 can be configured to possess dual
The function of noise reduction.
Similarly, in order to further reduce fluid noise, second can be set in second channel 12
Silencing means 22, produced another part fluid is flowed further to absorb wind in second channel 12
Noise.Second silencing means 22 is preferably configured to noise reduction chamber, and the noise reduction chamber has multiple
And take shape on the side wall of left and right two of second channel 12, from the aspect of Shooting Technique, noise reduction chamber more holds
Easily it is molded on the wall of air channel side, and manufacturing cost is relatively low.Along the flow direction of the apoplexy of second channel 12,
Multiple noise reduction chambers are set up in parallel on the side wall of second channel 12, can so be realized in second channel 12
The vertical regions of difference eliminate fluid noises, so as to reach more preferable noise reduction.Positioned at second channel 12
The vertical regions of difference some noise reduction chambers structure size it is basically identical, can so ensure silencing cavity
Room can eliminate the fluid noise of same frequency range simultaneously, reach more preferable noise reduction.It is being provided with
In the second channel 12 of noise reduction chamber, the resistance being subject to when being passed through due to wind flow is smaller, it is ensured that in list
Enter the cold wind air output of storage compartment 101 in the time of position by second channel 12.Second channel 12
Air channel structure so can take into account refrigeration and two functions of noise reduction simultaneously：On the one hand storeroom is maintained
The original cold wind air output in room 101 and reach its refrigeration performance, on the other hand again can reduce to greatest extent
The flow noise that fluid is produced in second channel 12.Noise reduction chamber is preferably configured to be Helmholtz
Acoustic resonator.Helmholtz resonator is as physics or a kind of basic sound absorption structure of acoustics, herein just not
Its principle and specific configuration expansion are repeated.
The silencing means of different zones is respectively used to eliminate the fluid noise of different frequency scope in air channel 10,
To reach the preferably overall fluid noise of reduction refrigerating appliance.Preferably, in first passage 11
One silencing means 21 can be set to the noise reduction blind hole of resistive silencing means, and the noise reduction blind hole is mainly used
In the fluid noise for eliminating high frequency scope, and the second silencing means 22 in second channel 12 can be with
The noise reduction chamber of resistant noise-reducing device is set to, and the noise reduction chamber is mainly used in eliminating lower frequency
The fluid noise of scope.First silencing means 21 and the second noise reduction are so set respectively in air channel 10
Device 22, can eliminate the fluid noise of bigger frequency range in air channel 10.
