Below with reference to Fig. 1 descriptions, embodiment is used for refrigerator according to a first aspect of the present invention（It is not shown）Ducting assembly
100。
As shown in figure 1, the ducting assembly 100 for refrigerator of embodiment according to a first aspect of the present invention, including：Air channel part
1st, rotary air valve 2 and knob 3.
Reference picture 1, rotary air valve 2 are located at the rear side of air channel part 1, and rotary air valve 2 is provided with rotary shaft 21, rotary shaft 21
Front end passes through air channel part 1, and knob 3 is located at the front side of air channel part 1, and knob 3 is provided with knob post 31, and the rear end of knob post 31 passes through
Screw（It is not shown）It is connected to rotary shaft 21.
Such as in the example of fig. 1, the rear side of air channel part 1 is provided with rotary air valve 2, and rotary shaft 21 is before rotary air valve 2
End face extends forward, and the front end of rotary shaft 21 passes through air channel part 1 from back to front, and rotary shaft 21 can rotate in air channel part 1, rotation
The rear open of button 3, the rear end face of knob post 31 from knob 3 extend back, and the rear end of knob post 31, which is connected by screw, is revolving
In rotating shaft 21.Further optionally, knob post 31 can be integrally formed with knob 3, and rotary shaft 21 can be with the one of rotary air valve 2
Shaping.
Together with being connected by screw with rotary shaft 21 due to knob post 31, knob post 31 can revolve together with rotary shaft 21
Turn, simultaneously as knob post 31 is fixed on knob 3, rotary shaft 21 is fixed on rotary air valve 2, when user's turning knob 3
When, rotary air valve 2 can follow knob 3 to rotate in the lump, so as to realize that the air quantity of refrigerator inside is adjusted, so, be connected by screw thread
Rotary air valve 2 and knob 3 are connect, the comfortableness of feel when user uses can be improved.
Ducting assembly 100 for refrigerator according to embodiments of the present invention, is connected by screw and securely fixes knob 3
On rotary air valve 2, so as to prevent knob 3 from coming off, and more preferable feel can be experienced when user's use.
In one embodiment of the invention, on knob post 31 formed with the first mounting hole 32, on rotary air valve 2 formed with
The second mounting hole 22 communicated with first mounting hole 32, screw sequentially pass through the second mounting hole 22, the first mounting hole 32 with
Rotary air valve 2 is connected on knob 3.As a result, screw is easier for installation, the structure of knob post 31 and rotary shaft 21
Simply, easily realize.
As shown in figure 1, the cross sectional shape of the first mounting hole 32 can be circle, and the first mounting hole 32 is from knob post 31
Rear end is recessed forward, and the second mounting hole 22 runs through forward from the rear end of rotary air valve 2, the second mounting hole 22 and the first installation
Hole 32 is connected, and screw is sequentially passed through into the second mounting hole 22 and the first mounting hole 32, so as to which rotary air valve 2 and knob 3 are firm
Ground links together.Here it is more convenient, smooth when so installing, it is necessary to which explanation, screw can be tapping screw.
Further, the second mounting hole 22 is stepped hole.Such as in the example of fig. 1, the section shape of the second mounting hole 22
Shape is circle, and the anterior area of section of the second mounting hole 22 is less than the area of section at the rear portion of the second mounting hole 22, so, the
The area of section of the rear end of two mounting hole 22 is equal with the area of section of the first mounting hole 32, and the free end of the bar portion of screw is through the
After two mounting holes 22, the screw cap of screw can be contained in the front portion of the second mounting hole 22（It is not shown）.
Yet further, reference picture 1, the front portion of rotary shaft 21 is formed with the receiving hole communicated with the second mounting hole 22, rotation
The rear end of button post 31 is stretched into receiving hole.
As shown in figure 1, receiving hole is backwardly recessed from the front end of rotary shaft 21, until receiving hole is connected with the second mounting hole 22
Logical, the area of section of receiving hole is more than the anterior area of section of the second mounting hole 22, so as to which knob post 31 can be from front to back
Receiving hole is stretched into, the rear end of knob post 31 can only be against the bottom surface of receiving hole（Such as the rear wall of the receiving hole shown in Fig. 1
Face）On, so, knob post 31 is just embedded in the axle of knob 3.Further, the internal face of receiving hole is formed as and the knob
The shape of the shape adaptation of the outside wall surface of post 31, for example, in one of example of the present invention, receiving hole and knob post 31
Cross sectional shape is circle, so that knob 3 can drive rotary shaft 21 to rotate when rotation, and then drives 2 turns of rotary air valve
It is dynamic, and be easy to assemble.Certainly, the invention is not restricted to this, in another example of the present invention, receiving hole is cut with knob post 31
Face shape can be ellipse, polygon and irregular shape being mutually adapted etc., allow knob 3 rotate when more
Stably drive rotary shaft 21 to rotate, ensure the reliability that rotary air valve 2 rotates.Further, it is also possible to improve the torsion of knob post 31
Square, increase rotation dynamics.
Further, so that the front end of rotary shaft 21 passes through, air channel part 1 leads to the through hole being formed through on air channel part 1
The axially extending extension 11 along through hole is provided with hole.
Such as in the example of fig. 1, through hole runs through air channel part 1 in the horizontal direction, extension 11 is connected on through hole, extension
The shape of cross section in portion 11 is circle, and formed with the connecting hole run through in the horizontal direction on extension 11, and rotary shaft 21 is from rear
Connecting hole is advanced through, and rotary shaft 21 can freely rotate in connecting hole, it is preferable that the shape of cross section of connecting hole and rotation
The shape of cross section of the periphery wall of rotating shaft 21 is circle.Alternatively, extension 11 can be integrally formed with air channel part 1.
Alternatively, the lateral dimension at the second mounting hole of correspondence 22 of rotary shaft 21 is more than the corresponding receiving hole of rotary shaft 21
The lateral dimension at place, i.e. rotary shaft 21 are formed as stepped.Such as in the example of fig. 1, the correspondence second of rotary shaft 21 is installed
Cross sectional shape at hole 22 is circular, its a diameter of H, and the cross sectional shape at the corresponding receiving hole of rotary shaft 21 is also circle, its
A diameter of h, and diameter h is less than diameter H, so as to which rotary air valve 2 only can be against on the rear end face of extension 11.
Alternatively, the length positioned at the front side of air channel part 1 of extension 11 be more than extension 11 be located at air channel part 1 after
The length of side.For example, in the example of fig. 1, the front end face of extension 11 to the horizontal range at the center of through hole is L2, extension
11 rear end face to the horizontal range at the center of through hole be L1, L1Value be less than L2Value.
The refrigerator of embodiment according to a second aspect of the present invention, including be used for according to above-mentioned first aspect embodiment of the invention
The ducting assembly 100 of refrigerator.
Refrigerator according to embodiments of the present invention, by the ducting assembly for refrigerator for setting above-mentioned first aspect embodiment
100, so as to improve the overall performance of refrigerator.
