The air duct, the air guide assembly and the air conditioner according to some embodiments of the present invention will be described with reference to fig. 1 to 10.

As shown in fig. 7, an embodiment of the first aspect of the present invention provides a wind tunnel 130, wherein the wind tunnel 130 is formed with an airflow channel 131 inside, the airflow channel 131 includes a first curved section 1311 and a second curved section 1312, one end of the second curved section 1312 is opposite to and joined with one end of the first curved section 1311, and the other end of the second curved section 1312 is formed as an outlet 136.

The utility model discloses above-mentioned embodiment provides a wind channel 130, its airflow channel 131 include the first bend section 1311 and the second bend section 1312 that link up each other and communicate, compare in current spiral case 132 formula wind channel 130 and have gone out a bend structure more, and compared in traditional axial flow wind channel 130 and have gone out two bend structures more. Through the design, on the one hand, the length, curvature and the like of the second curve section 1312 are adjusted, the position and orientation of the outlet 136 of the air duct 130 can be adjusted more flexibly, the limitation of the air outlet direction of the traditional volute 132 type air duct 130 and the axial flow type air duct 130 is broken through, and therefore the diversified position relation between the air outlet 1001 and the air inlet (such as the first air inlet structure 112 and the second air inlet structure 122) in the air conditioner can be better matched, the air outlet form is richer, and the popularization in the field is facilitated. On the other hand, compared to the volute 132 type air duct 130, by the two-stage curved design including the first curved section 1311 and the second curved section 1312, the first curved section 1311 can be used to match the fan 300 or the wind wheel to meet the requirements of wind pressure control and air flow straightening, and the second curved section 1312 is used to guide the air flow to turn again after the first curved section 1311, so that the air flow discharged from the outlet 136 of the air duct 130 can obviously carry on deflection inertia due to the guide of the second curved section 1312 before being discharged, and thus, a certain swirling phenomenon can be generated under the action of the deflection inertia after the air flow is discharged from the outlet 136 of the air duct 130 to form a spiral air flow, which is softer in air outlet, thereby improving the use experience of products.

More specifically, as shown in fig. 7, the air guide surface of the channel has a first side surface and a second side surface, and the first side surface and the second side surface are distributed opposite to each other and at intervals, so that the air flow channel 131 is defined between the first side surface and the second side surface. The first side surface is provided with a first convex surface and a first concave surface, the first convex surface is in transitional connection with the first concave surface, the second side surface is provided with a second convex surface and a second concave surface, the second convex surface is in transitional connection with the second concave surface, the first convex surface is opposite to the second concave surface, a first curve section 1311 is defined between the first convex surface and the second concave surface, the second convex surface is opposite to the first concave surface, and a second curve section 1312 is defined between the second convex surface and the first concave surface.

Example 1:

as shown in fig. 7, in addition to the features of the above embodiment, further defined are: the air duct 130 includes a volute 132 and a volute tongue 133, the air guide surface of the volute tongue 133 is disposed opposite to the air guide surface of the volute 132 and defines a first curved section 1311, and in detail, the air guide surface of the volute tongue 133 provides a first convex surface, and the air guide surface of the volute 132 provides a second concave surface, and the first curved section 1311 is defined by two opposite surfaces, namely a convex surface and a concave surface. Therefore, the matching performance of the first curve section 1311 and the wind wheel or the fan 300 can be improved, and the requirements of wind pressure control and airflow straightening are better met.

Of course, the volute 132 and the volute tongue 133 defining the first curve segment 1311 are preferred embodiments of the present design, and in other embodiments, one skilled in the art may construct the first curve segment 1311 with other types of curved structures as desired.

Example 2:

as shown in fig. 7, in addition to the features of embodiment 1 described above, there are further defined: the air duct 130 further comprises an air guide wall 134, the air guide surface of the air guide wall 134 is in a concave arc shape, and the air guide surface of the air guide wall 134 is in transitional connection with the air guide surface of the volute tongue 133; the end of the volute 132 adjacent to the outlet 136 is provided with a tab 135, and the wind guiding surface of the tab 135 is opposite to the wind guiding surface of the wind guiding wall 134, so that the wind guiding wall 134 and the tab 135 define a second curve section 1312. Therefore, the transition smoothness between the first curve section 1311 and the second curve section 1312 can be ensured more easily, the wind resistance is reduced, the structural design of the product is simplified, and the design has the advantage of convenience in processing and manufacturing.

In addition, because the wind guide surface of the wind guide wall 134 is concave arc, on one hand, on the premise of avoiding excessive increase of wind resistance by using arc transition formed by the concave arc wind guide surface, the backward inclination amount of the outlet 136 of the air duct 130 can be restrained, so that the air outlet of the air duct 130 is closer to the lower side or the front side, the air supply of the air conditioner is realized towards or forwards, on the other hand, the design idea that a straight air guide wall 134 is formed between the volute tongue 133 (or the volute 132) and the outlet 136 in the traditional structure is changed, the design utilizes the arc-shaped flow guide effect formed by the concave arc-shaped air guide surface, the air flow discharged from the volute tongue 133 can have a certain deflection inertia after passing through the air guide surface of the air guide wall 134, like this, the air current can produce certain phenomenon of circling round under the effect of deflection inertia after discharging from export 136 to make the air-out of air conditioner softer, promote the use of product and experience.

Preferably, as shown in fig. 7, the wind guiding surface of the wind guiding wall 134 is circular arc, and the length thereof is preferably 1/4 circular arc, but the length thereof can also be designed to be greater than or less than 1/4 circular arc according to specific requirements.

Example 3:

This is advantageous in ensuring smooth airflow on the air guide surface of the tab 135, reducing drag loss of the airflow at the tab 135, and reducing airflow noise by preventing back pressure from being easily generated at a portion of the tab 135 adjacent to the outlet 136.

Example 4:

as shown in fig. 7, in addition to the features of any of the above embodiments, further defined are: one end of the air guide surface of the tongue 135 is connected with the air guide surface of the volute 132, and the other end of the air guide surface of the tongue 135 and the air outlet end 1341 of the air guide wall 134 define an outlet 136. Thus, the deflection inertia of the airflow discharged from the air duct 130 can be kept high, and the problem that the deflection inertia of the airflow is dissipated is avoided.

For example, as shown in fig. 7, the tongue 135 is formed by a convex arc wall, which is substantially C-shaped, and the convex arc wall is located at one end of the opening of the C-shape to be connected to the volute 132, and the convex arc wall is located at the other end of the opening of the C-shape to define the outlet 136 with the air outlet end 1341 of the air guide wall 134.

It is understood that the shape of the air flow channel 131 is S-shaped, and not specifically the shape of the air flow channel 131 is strictly precise "S" shape, and here, the S-shape should be understood macroscopically to include "S" shape and to ensure that other shapes such as Z-shape, sine shape, etc. are approximated to "S". Alternatively, macroscopically understood to mean that the airflow channel 131 is substantially S-shaped.

In the present embodiment, the airflow channel 131 is provided with an S shape (for example, as shown in fig. 7, a dotted arrow in fig. 7 generally indicates the flow direction and path of the airflow along the air duct 130, the entire airflow channel 131 of the air duct 130 is generally S-shaped, and the flow direction and path of the airflow along the air duct 130 are correspondingly controlled to be generally S-shaped), which breaks through the air outlet angle limitation of the conventional volute type air duct, can adjust the orientation of the outlet 136 more flexibly, and can turn and guide the airflow again before the outlet 136, so that the airflow discharged from the air duct 130 can obviously bring deflection inertia, so that the airflow forms a spiral airflow when separating from the air duct 130, the air outlet softness is improved, and the use experience of the product is improved.

As shown in fig. 8, 9 and 10, an embodiment of the second aspect of the present invention provides an air guide assembly, including: in the wind tunnel 130 and the wind deflector 181 described in any of the above embodiments, as shown in fig. 7, the wind deflector 181 is disposed on the leeward side of the wind guide wall 134 of the wind tunnel 130, and the wind deflector 181 moves relative to the wind tunnel 130, so that at least a portion of the wind deflector 181 protrudes from the wind outlet end 1341 of the wind guide wall 134 and extends along the extension line of the wind guide wall 134 (as shown in fig. 8, 9 and 10).
