The following description will be made by taking an example of the operation in the cooling mode of the outdoor unit of the general household separate air conditioner. In the refrigeration working process of the air conditioner, the fan of the outdoor unit works, and air is sucked from the air inlet in the back of the outdoor unit. The air then flows through the outdoor unit heat exchanger surface and is blown out by the fan from the air outlet in front after the heat exchange is completed. Therefore, the outdoor unit of the air conditioner has both "suction" and "discharge". The working principle of the air conditioner also determines that enough space is ensured around the outdoor unit during the process of using the air conditioner at ordinary times, the ventilation is smooth, no close-distance sheltering object is needed, and no leaves, leathers, plastic bags and the like are needed to be attached to the back surface of the outdoor unit, so that the circulating air quantity and the heat dissipation effect of the outdoor unit are ensured, and the good refrigeration effect of the air conditioner is ensured. With the development of urban building design, urban high-rise buildings seek compatibility of external beauty and internal functions more and more, utilize advanced air conditioning technology and equipment at home and abroad outside and meet the requirements of relevant national and industrial specifications and regulations, and limit the installation position of an air conditioner more and more in order to create healthy and comfortable indoor air quality and environment. In most cases, the outdoor unit of the air conditioner is designed to be installed in a concealed manner in the form of shutters or grills. The installation mode has certain blocking effect on the outlet air of the outdoor unit of the air conditioner, and particularly has the effect of reflecting the outlet air when the grid strips are obliquely arranged, so that hot air can be reflected to the periphery of the air conditioner. The grille and the peripheral auxiliary structure seriously affect the heat dissipation air duct of the outdoor unit of the air conditioner, so that a large amount of hot air is concentrated near the air conditioner table to wrap the whole outdoor unit. Such a high temperature environment affects not only the heat transfer efficiency of the outdoor unit radiating fins but also the indoor cooling effect, thereby affecting the performance of the air conditioner.
In order to reduce this effect, the cooling and heating experience of the user using the air conditioner is satisfied. The Chinese patent application: CN 110836419 a discloses an air guiding device and an air conditioner outdoor unit. The air guide device comprises an induced air duct structure with a telescopic elastic structure, and the inlet end of the induced air duct structure is configured to be connected with an air outlet of the air conditioner outdoor unit; the outlet end of the induced air duct structure is configured to be connectable to a windowsill grille at the air conditioner mounting deck. Wherein, induced air wind channel structure can change its length and direction of buckling through scalability structure to make the exit end can install the front portion or the top or the side portion of windowsill grid, in order to change the air-out direction of air current. Therefore, the air flow coming out of the air outlet can be discharged from the gap of the windowsill grating along the induced air duct through the induced air duct structure, so that the temperature of the working environment around the external machine is effectively reduced, meanwhile, the phenomenon that the return air enters the heat exchanger to influence the heat exchange efficiency is avoided, and the indoor refrigeration efficiency is improved. However, the cross-sectional area of the passage of such an air inducing device cannot be adjusted, and the versatility thereof is to be improved.
Accordingly, there is a need in the art for a new solution to the above problems.

The angle and magnitude of rotation of the blade 252 depends on the length and arc of the displacement groove 531.
Fig. 13 is a plan view schematically showing the structure of an embodiment of the first opening state of a plurality of blades in the adjustment portion in an embodiment of the air inducing apparatus of the present invention; fig. 14 is a plan view schematically showing the structure of an embodiment of the second opening state of a plurality of blades in the adjustment portion in an embodiment of the air inducing apparatus of the present invention; fig. 15 is a schematic plan view of the structure of an embodiment of the third opening state of the plurality of blades in the adjustment portion in the embodiment of the wind-guiding device of the present invention. As shown in fig. 13-15, in one or more embodiments, the driving portion (not shown) is configured to simultaneously drive the plurality of blades 252 to move along the respective moving slots 531 via the moving rod 522, and to enable the plurality of blades 252 to rotate about the respective matching connecting shafts 254. During synchronous rotation of the plurality of blades 252, the size of the central aperture 255 formed by the inner edges 252c of the plurality of blades 252 may change as the plurality of blades 252 rotate.
As shown in fig. 13, when the moving rods 522 of the plurality of blades 252 are synchronously driven by the driving unit to move to the outer ends 531b of the corresponding moving grooves 531, the center hole 255 surrounded by the inner edges 252c of the plurality of blades 252 is maximized, that is, the plurality of blades 252 are in the fully open state 252 c. As shown in fig. 14, when the moving rods 522 of the plurality of blades 252 are synchronously driven by the driving unit to move to the substantially middle positions of the corresponding moving grooves 531, the center hole 255 formed by the inner edges 252c of the plurality of blades 252 is substantially half of the maximum opening, that is, the blades 252 are in the half-open state 252 b. As shown in fig. 15, when the moving rods 522 of the plurality of blades 252 are synchronously driven by the driving unit to move to the inner ends 531a of the corresponding moving grooves 531, the center holes 255 formed by the inner edges 252c of the plurality of blades 252 are closed, that is, the plurality of blades 252 are in the fully closed state 252 a. Therefore, the size of the cross section of the induced air channel body 32 can be adjusted by adjusting the opening degree of the blade 252.
FIG. 16 is a schematic expanded plan view of an embodiment of a duct wall in another embodiment of an air-inducing apparatus of the invention; fig. 17 is a schematic closed plan view of an embodiment of a passage wall in another embodiment of an air-inducing device of the invention. As shown in fig. 16 and 17, in an alternative embodiment, the induced draft channel body 32 may not include the adjustment portion 325, and the induced draft channel body 32 may be configured to be enclosed by the channel wall 324. As shown in fig. 16 and 17, in one or more embodiments, the flexible or pliable channel wall 324 has opposing channel wall first and second edges 324a, 324b, overlapping and conforming the channel wall first and second edges 324a, 324b to enclose a closed channel shape.
Based on the orientation shown in fig. 17, the inner side of channel wall first edge 324a conforms to the outer side of channel wall second edge 324 b. Alternatively, the outer side of channel wall first edge 324a fits inside of channel wall second edge 324 b. The portion of channel wall first edge 324a that overlaps channel wall second edge 324b is referred to as overlap 3241. By adjusting how much of the overlap 3241, the size of the inner diameter of the channel enclosed by the channel wall 324 can be varied. In other words, the more portions of the channel wall first edge 324a and the channel wall second edge 324b overlap, the smaller the inner diameter of the channel enclosed by the channel wall 324, and vice versa. Thus, by adjusting the overlapping portion 324, it is possible to change the cross section of the induced air passage body 32 to enhance the versatility of the induced air passage.
Based on the above-mentioned embodiment that the channel wall 324 with variable cross-sectional area encloses the induced air channel body 32, the structure of the corresponding first connecting portion 321 and second connecting portion 322 at the first end 32a and the second end 32b is changed correspondingly. As shown in fig. 3, the first connection portion 321 and the second connection portion 322 at the first end 32a and the second end 32b are respectively ring structures extending to the outside and the inside of the air inducing channel body 32. Based on the orientation shown in fig. 3, when the inner side of the first edge 324a of the channel wall is attached to the outer side of the second edge 324b of the channel wall, the first edge and the second edge at the first connecting portion 321 will also overlap in the horizontal direction, and likewise, the first edge and the second edge at the second connecting portion 322 will also overlap in the horizontal direction, since the elastic portion 323 is provided between the first end 32a and the second end 32b, so as to allow the first connecting portion 321 and the second connecting portion 322 to have a suitable amount of deformation in the horizontal direction.
As shown in fig. 4 to 6, in the embodiment of enclosing the air inducing duct body 32 by the duct wall 324 with variable cross-sectional area, the connection modes of the first connection portion 321 and the second connection portion 322 with the casing 12 and the air exhausting connection portion 21 are adjusted accordingly as required. When the induced draft passage body 32 surrounded by the passage wall 324 is adjusted to be matched with the air outlet 13, the first connection portion 321 is provided with a first connection hole 3211 matched with the housing connection hole, and then the first tie 31a or the first screw 31b connects the first connection portion 321 with the housing 12. Similarly, a second connection hole 3221 is provided in the second connection portion 322 to match the exhaust connection portion 21, and the second connection portion 322 is connected to the exhaust connection portion 21 by a second tie 33a or a second screw 33 b.
In the case of using the coupling member of the first and second magnetic members 31c and 33c, a magnetic material may be coated on the first coupling portion 321, the second coupling portion 322, the periphery of the case coupling hole (not shown in the drawings), and the discharge air coupling portion 21, so as to achieve the coupling of the case 12 with the first coupling portion 321 by the magnetic force of the first magnetic member 31c and the coupling of the discharge air coupling portion 21 with the second coupling portion 322 by the magnetic force of the second magnetic member 33 c. Alternatively, the first connector 31 and the second connector 33 may adopt different forms of connectors or the first connector 31 and the second connector 33 may be provided in other suitable forms of connection.
