Detailed description of the invention
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.
Below with reference to the accompanying drawings the ducting assembly according to the embodiment of the present invention is described in detail.
As shown in Figure 2, according to the ducting assembly of the embodiment of the present invention, comprising: spiral case 10, centrifugal blower 20 and annular guide duct 30.
Specifically, centrifugal blower 20 is located in spiral case 10.Advantageously, the molded line of spiral case 10 is spiral of Archimedes.
Annular guide duct 30 has main air inlet 301 and main air outlet 302.Main air inlet 301 is communicated with the air outlet 101 of spiral case 10.Advantageously, main air inlet 301 is relative with main air outlet about 302.Annular guide duct 30 is also provided with spaced apart multiple secondary air outlet 305.
According to the ducting assembly of the embodiment of the present invention, centrifugal blower realizes the speed-raising pressurization of air-flow in spiral case, through spiral case diffusion and the conveying of laggard row airflow circulating is stablized in flow field, effectively can reduce aerodynamic noise, promote user user satisfaction.
According to an example of the present invention, the inner ring of annular guide duct 30 is configured to the first bending wind deflector 303 bent outwardly towards the part of the air outlet 101 of spiral case 10.Thus, the air-flow that can export the air outlet 101 by spiral case 10 distributes.
Advantageously, as shown in Figure 2, in the horizontal plane, the projection interval predetermined distance d at the projection of the bending part of the first bending wind deflector 301 and the center of centrifugal blower 20.Further, described predetermined distance d can be 10mm.
That is, the position on the top of the first bending wind deflector 301 is to the ratio of distribution of air flow and direction important.Consider the offset characteristic of centrifugal blower 20 air-out direction, the position on the top of the first bending wind deflector 301 should be departed from slightly with the center of centrifugal blower 20.As shown in Figure 2, centrifugal blower 20 is according to rotating clockwise, then the position on the top of the first bending wind deflector 301 is positioned at the 10mm place, left side at the center of centrifugal blower 20.
According to an example of the present invention, the inner ring of annular guide duct 30 is configured to the second bending wind deflector 304 bent outwardly towards the part of main air outlet 302.Advantageously, the bending part of the second bending wind deflector 304 is just to the center of main air outlet.Thus, air-flow enters in the main body of annular guide duct 30 at main air inlet 301 place after the first bending wind deflector 302 distributes, and fraction can flow out from secondary air outlet 305.When residual gas stream arrives main air outlet 302 place, again collect through the second bending wind deflector 304, flow out from main air outlet 302.
According to the ducting assembly of the embodiment of the present invention, centrifugal blower realizes the speed-raising pressurization of air-flow in spiral case, through spiral case diffusion and flow field stable after enter in annular guide duct, pneumatic convey is carried out through main air outlet and secondary air outlet, and effective distribution of air-flow is realized by the reasonable Arrangement of the first bending wind deflector, the second bending wind deflector, main air outlet and secondary air outlet, effectively can improve distribution of air flow and reduce aerodynamic noise.
When being arranged on the refrigeration plants such as such as refrigerator, refrigerator, showcase according to the ducting assembly of the embodiment of the present invention, aerodynamic noise is low, and distribution of air flow is reasonable, greatly improves the user satisfaction of user.
