The window type air conditioner air duct assembly 100 can effectively reduce noise of a window type air conditioner and improve user experience.

Referring to fig. 2, fig. 2 is a schematic view illustrating a connection structure between the volute 110 and the wind wheel 120 of the window air conditioning duct assembly 100.

The volute 110 includes a combined back plate 111, a cover plate 112, and a surrounding plate 113 disposed between the combined back plate 111 and the cover plate 112, the combined back plate 111, the cover plate 112, and the surrounding plate 113 together enclose an inner space of the volute 110, and the wind wheel 120 is mounted on the combined back plate 111. An air inlet 1121 is formed through the cover plate 112, the wind wheel 120 corresponds to the air inlet 1121 and is used for sucking external air into the volute 110 through the air inlet 1121, the combined back plate 111, the cover plate 112 and the surrounding plate 113 jointly define an air outlet 114, and an air flow sucked into the volute 110 flows in an air duct of the volute 110 under the centrifugal action, so that the air flow is blown out of the air outlet 114.

Considering that in practical applications, the airflow sucked from the air inlet 1121 will flow to the surface of the combined back plate 111 at a large angle under the action of the wind wheel 120, and in order to avoid the airflow from being strongly squeezed on the surface of the combined back plate 111, the airflow flowing direction is disordered, and large noise is generated, in this embodiment, a trumpet-shaped rectifying cavity 1111 with an opening facing the cover plate 112 is concavely arranged on the inner wall of the combined back plate 111, and the wind wheel 120 is arranged in the rectifying cavity 1111 and corresponds to the air inlet 1121.

The arrangement of the rectifying cavity 1111 is equivalent to increase the axial distance between the molded line of the combined back plate 111 and the molded line of the volute 110, so that when the airflow flowing in the molded line direction collides with the gas accumulated on the surface of the combined back plate 111, the airflow can obtain enough rectifying space from the rectifying cavity 1111, thereby avoiding the flow direction confusion caused by the extrusion of the airflow, ensuring the orderly flow direction to the air outlet 114 in the operation process of the wind wheel 120, and avoiding the generation of noise.

In this embodiment, on the plane where the axis of the rectifying curved plate 116 is located, the opening angle of the rectifying curved plate 116 is in the range of 150 ° to 160 °, that is, on the plane where the axis of the rectifying curved plate 116 is located, the included angle B between the rectifying curved plate 116 and the mounting flat plate 115 is in the range of 10 ° to 15 °, so that the airflow accumulated in the rectifying cavity 1111 can be ensured to enter the circumferential air duct of the volute 110 at a gentle angle, and strong impact caused by an excessively large entering angle is avoided.

The combined back plate 111 further comprises a flow guide plate group, one part of one end, far away from the installation flat plate 115, of the flow guide curved plate 116 is connected with one end, far away from the cover plate 112, of the surrounding plate 113, the other part of the other end of the flow guide curved plate is connected with one end of the flow guide plate group and is in smooth transition, two opposite sides of the flow guide plate group are connected with the surrounding plate 113, and one end, far away from the flow guide curved plate 116, of the flow guide plate group, the surrounding plate 113 and the cover plate 112 form an air outlet 114.

In practical applications, when the airflow on the surface of the curved flow-straightening plate 116 flows out of the curved flow-straightening plate 116 along the profile of the volute 110, the airflow can enter the flow-guiding plate set in a smooth transition state, and then flows out of the volute 110 through the air outlet 114 under the guidance of the flow-guiding plate set, so that the impact between the airflow and the solid structure at the connection position of the curved flow-straightening plate 116 and the flow-guiding plate set is avoided, and the noise is further reduced.

The part of the outer edge of one end of the rectifying curved plate 116 far away from the installation flat plate 115, which is connected with the guide plate group, is provided with a radius R ₁ In the range of 100mm to 110 mm. The part that rectification bent plate 116 and guide plate group are connected is arc, guarantees that the air current in rectification chamber 1111 can disperse under the centrifugal action and flow into guide plate group, avoids the air current too concentrate and takes place the extrusion, further promotes the noise reduction effect.

In order to solve this problem, in this embodiment, the transition straight plate 117, the flow guiding curved plate 118, and the flow guiding straight plate 119 of the flow guiding plate set are sequentially connected and smoothly transited, and the transition straight plate 117 is connected and smoothly transited with the flow guiding curved plate 116, so that the air flow flowing out from the surface of the flow guiding curved plate 116 is smoothly guided to the air outlet 114.
