DETAILED DESCRIPTION

[0044] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0045] In the present disclosure, the orientation words such as "upper, lower" used without the opposite description generally refer to the upper and lower in the space of the air conditioner when it is in use. "Inner, outer" refers to the inner and outer relative to the outline of the component or structure itself. In addition, it should be noted that the terms such as "first, second" used are to distinguish one element from another element, and do not have sequentiality and importance. In addition, in the description referring to the drawings, the same marks in different drawings represent the same elements.

[0046] According to a first aspect of the present disclosure, a duct device is provided, referring to Figures 1 to 9 The duct device includes a duct structure 1 and a light-emitting assembly 2, wherein the duct structure 1 has a duct 110 and a first air port 120 communicating with the duct 110, and the inner wall surface 150 of the duct structure 1 surrounding the duct 110 has a light area 130; the light-emitting assembly 2 is connected to the duct structure 1 and includes a light-emitting piece 210, which is used to emit light to the light area 130, so that at least part of the light passing through the light area 130 can be observed through the first air port 120 from outside the first air port 120.

[0047] Through the above technical solution, that is, the duct device provided by the present disclosure, the light-emitting piece 210 connected to the duct structure 1 is used to emit light to the light area 130 on the inner wall surface 150 of the duct structure 1 surrounding the duct 110, so that at least part of the light passing through the light area 130 can be observed through the first air port 120 from outside the first air port 120. Such arrangement can improve the lamp effect atmosphere at the first air port 120 when the light area 130 irradiated by the light-emitting piece 210 presents a light effect such as lamp light effect, and by adaptively adjusting the light-emitting effect of the light-emitting piece 210, for example, the free switching of different light effects can be realized, which helps to improve the aesthetics and user experience of the air conditioner, for example.

[0048] In addition, since the light on the light area 130 can be observed through the first air port 120, for example, the light effect such as the light effect presented by the light area 130 irradiated by the light-emitting piece 210 can be observed through the first air port 120, compared with the lamp structure directly exposed to the air conditioner arrangement and the direct light of the lamp to the human eye in the related art, the light effect provided by the present disclosure is relatively soft, which can reduce visual fatigue, and can also realize the hidden arrangement of the light-emitting piece 210, avoiding the direct exposure arrangement of the lamp structure in the related art. Therefore, the present disclosure can realize the simplification of the external structure of the air conditioner after hiding the light-emitting piece 210, which helps to improve the aesthetics of the air conditioner, for example, and can reduce the possibility of the problem of dust accumulation on the surface of the light-emitting piece 210, and improve the lamp effect atmosphere and light effect at the first air port 120.

[0049] Among them, it should be noted that when the illumination area 130 illuminated by the light-emitting element 210 presents light effects such as lighting effects, the above-mentioned light effects can be the effects produced after the light is irradiated to the illumination area 130, for example, it can present light effects such as light color or a combination of different light colors, and it can be understood that the image formed after the light is irradiated on the illumination area 130 can present, for example, different light curtain effects, and the light curtain effects can include but are not limited to light effects such as light color changes, brightness changes, flickering or changes in illumination position. The present disclosure does not make specific limitations on this. Its purpose is to be able to enhance the lighting atmosphere at the first air outlet 120, so as to achieve the purpose of improving, for example, the aesthetics of the air conditioner and the user experience.

[0050] In some embodiments, reference Figures 3 to 5 As shown, the illumination area 130 can be arranged relative to the position of the first air outlet 120 so that at least part of the light is reflected by the illumination area 130 and then emitted through the first air outlet 120. This arrangement makes it easy to observe the light on the illumination area 130 through the first air outlet 120, and by emitting the lighting effect at the illumination area 130 through the first air outlet 120, the lighting atmosphere and sense of space at the first air outlet 120 can also be improved.

[0051] In some embodiments, reference Figures 3 to 5 As shown, the air duct structure 1 may have a second air outlet 140 connected to the air duct 110, and the inner wall surface 150 of the air duct structure 1 has a turning portion 160, so that the air duct 110 is at least partially turned between the first air outlet 120 and the second air outlet 140, and the illumination area 130 is located on the turning portion 160, and the projection of the turning portion 160 in a direction perpendicular to the plane defined by the first air outlet 120 is at least partially located in the first air outlet 120, so that the light reflected by the illumination area 130 is emitted through the first air outlet 120. With such an arrangement, it is possible to realize adaptive adjustment of the air outlet direction of the air duct 110 by emitting the lighting effect at the illumination area 130 through the first air outlet 120.

[0052] Among them, Figures 3 to 5 As shown, the turning portion 160 may include a curved portion, that is, it can be understood that the inner wall surface 150 of the air duct structure 1 may be, for example, a curved surface, which can make the air duct 110 extend at least partially in a curve between the first air outlet 120 and the second air outlet 140. In this way, by setting the curved portion, the turbulence and impact of the air flow in the air duct 110 can be reduced, the air flow resistance can be reduced, and it is helpful to reduce operating noise and improve air supply efficiency.

[0053] In addition, in some other alternative embodiments not shown in the figure, the turning portion 160 may also include a planar portion, that is, it can be understood that the inner wall surface 150 of the air duct structure 1 may also be, for example, a slope, so that the air duct 110 can at least partially extend in an oblique line between the first air outlet 120 and the second air outlet 140, or, in some other alternative embodiments not shown in the figure, the turning portion 160 may also include the above-mentioned curved surface portion and the planar portion at the same time. The present disclosure does not specifically limit this type of deformation method, and those skilled in the art can adaptively design it according to actual application requirements.

[0054] In addition, in some embodiments, reference Figures 3 to 5 As shown, the air duct structure 1 may include an air duct wall plate 170, which encloses an air duct 110, a first air outlet 120, and a second air outlet 140. The air duct wall plate 170 has a light-transmitting portion 180 and an illumination area 130. The light-emitting component 2 is arranged on a side of the light-transmitting portion 180 away from the interior of the air duct 110 to emit light to the illumination area 130 through the light-transmitting portion 180. That is, it can be understood that by arranging the light-emitting component 2 outside the air duct 110 of the air duct structure 1 and making The light emitted by the light-emitting element 210 passes through the light-transmitting portion 180 and illuminates the illumination area 130 in the air duct 110. This arrangement ensures that the light irradiated into the illumination area 130 forms, for example, a lighting effect in the illumination area 130. At the same time, since the light-emitting component 2 is located outside the air duct 110 of the air duct structure 1, the light-emitting component 2 is prevented from occupying the internal space of the air duct 110, thereby ensuring that the air duct structure 1 has a good air outlet effect and air supply efficiency, which helps to improve the overall performance of the air conditioner.

[0055] Among them, such as Figures 3 to 5 As shown, the air duct wall panel 170 may include a first plate body 171 and a second plate body 172 arranged relatively to each other, one of the first plate body 171 and the second plate body 172 is provided with a light-transmitting portion 180, and the other has an illumination area 130 (the illumination area 130 is located on the turning portion 160). Such arrangement allows the light emitted from the light-emitting component 210 provided on the side of the light-transmitting portion 180 away from the interior of the air duct 110 to directly illuminate the illumination area 130 in the air duct 110 after passing through the light-transmitting portion 180, thereby shortening the path of the light and reducing energy loss, ensuring that the light irradiated into the illumination area 130 forms a better lighting effect in the illumination area 130, and improving the lighting atmosphere and sense of space at the first air outlet 120.

[0056] For example, in some embodiments, reference Figures 3 to 5As shown, the first plate 171 can be located above the second plate 172, the first plate 171 is provided with a light-transmitting portion 180, and the second plate 172 has an illumination area 130. This arrangement allows the light emitted from the light-emitting component 210 provided on the side of the light-transmitting portion 180 away from the inside of the air duct 110 to pass through the light-transmitting portion 180 and directly illuminate the illumination area 130 in the air duct 110, and can form a better lighting effect in the illumination area 130.

[0057] It can be understood that the above-mentioned first plate 171 can be located above the second plate 172, the first plate 171 is provided with a light-transmitting portion 180, and the second plate 172 has an illumination area 130. The specific embodiment is exemplary. In other alternative embodiments not shown in the figures, the above-mentioned first plate 171 can also be located below the second plate 172, the first plate 171 is provided with a light-transmitting portion 180, and the second plate 172 has an illumination area 130. The present disclosure is not limited to this. The purpose is to enable the light emitted by the light-emitting component 210 to pass through the light-transmitting portion 180 and directly illuminate the illumination area 130 in the air duct 110, and to form a better lighting effect in the illumination area 130. Those skilled in the art can design adaptively according to actual application requirements.

[0058] In addition, in some embodiments, reference Figures 3 to 5 As shown, the first plate body 171 may include a first plate portion 1711, a light-transmitting portion 180 and a second plate portion 1712. The extension directions of the first plate portion 1711 and the second plate portion 1712 form an angle, and the light-transmitting portion 180 is connected between the first plate portion 1711 and the second plate portion 1712. In addition, the second plate body 172 may include a third plate portion 1721, a fourth plate portion 1722 and a fifth plate portion 1723 connected in sequence. The extension directions of the third plate portion 1721 and the fifth plate portion 1723 form an angle, and the illumination area 130 is provided on the fourth plate portion 1722. The light-transmitting portion 180 is connected between the first plate portion 1711 and the second plate portion 1712. It is constructed as a curved plate body or a flat plate body protruding toward the illumination area 130. Such an arrangement makes it easy for the light emitted from the light-emitting part 210 arranged on the side of the light-transmitting portion 180 away from the inside of the air duct 110 to pass through the light-transmitting portion 180 and directly illuminate the illumination area 130 in the air duct 110 (that is, the illumination area 130 on the fourth plate portion 1722). This can shorten the path of the light and reduce energy loss, ensuring that the light irradiated into the illumination area 130 forms a better lighting effect in the illumination area 130, thereby improving the lighting atmosphere and sense of space at the first air outlet 120.

[0059] It can be understood that, due to the arrangement of the extension directions of the first plate portion 1711 and the second plate portion 1712 at an angle, and the arrangement of the extension directions of the third plate portion 1721 and the fifth plate portion 1723 at an angle, the orientation direction of the first air outlet 120 of the air duct 110 can be changed adaptively according to the blowing direction of the air duct 110 by changing the angle value of the corresponding angle, thereby improving the applicability of the air conditioner. It should be noted that the specific angle value of the angle between the extension directions of the first plate portion 1711 and the second plate portion 1712, and the specific angle value of the angle between the extension directions of the third plate portion 1721 and the fifth plate portion 1723 are not limited in the present disclosure, and can be designed adaptively according to actual application requirements by those skilled in the art.

[0060] In addition, it should be noted that the specific connection mode of the first plate portion 1711, the light-transmitting portion 180, and the second plate portion 1712 is not limited in the present disclosure, and can be designed adaptively according to actual application requirements by those skilled in the art. For example, the first plate body 171 can include the first plate portion 1711, the light-transmitting portion 180, and the second plate portion 1712 connected in sequence, and in order to ensure that the connection has good sealing effect, the corresponding connection position can be sealed and connected by, for example, adhesive, so as to ensure that the first plate body 171 has high structural strength, and the air duct 110 has high sealing performance. Alternatively, the first plate body 171 can include the first plate portion 1711 and the second plate portion 1712 connected, and a mounting opening (not shown) is formed between the first plate portion 1711 and the second plate portion 1712. The light-transmitting portion 180 includes, for example, a light-transmitting plate sealed and connected to the mounting opening. For example, the light-transmitting plate can be sealed and fitted to the first plate portion 1711 and the second plate portion 1712 and cover the mounting opening. The present disclosure is not limited to this, and the purpose is to ensure that the first plate body 171 has high structural strength, and the air duct 110 has high sealing performance. Those skilled in the art can design adaptively according to actual application requirements.

[0061] In addition, the specific connection mode of the third plate portion 1721, the fourth plate portion 1722, and the fifth plate portion 1723 is not limited in the present disclosure, and can be designed adaptively according to actual application requirements by those skilled in the art. For example, the third plate portion 1721, the fourth plate portion 1722, and the fifth plate portion 1723 can be arranged integrally or assembled. The purpose is to ensure that the second plate body 172 has high structural strength, and the air duct 110 has high sealing performance.

[0062] In addition, in some embodiments, with reference to Figures 3 to 5As shown, the air duct wall plate 170 can include two side plates 173 arranged oppositely and connected between the first plate body 171 and the second plate body 172, and the first plate body 171, the second plate body 172 and the two side plates 173 together enclose the air duct 110, the first air outlet 120 and the second air outlet 140. In this way, the air duct structure 1 can ensure that the air duct 110 stably sends air, and the overall structure arrangement is relatively simple and convenient to install and manufacture.

[0063] In order to facilitate the light emitted by the light emitting member 210 to directly irradiate the illumination area 130 in the air duct 110 after penetrating the light-transmitting part 180, in some embodiments, the light-transmitting part 180 can include at least one of a transparent ABS plate, a light-transmitting polycarbonate plate, an acrylic plate or a glass plate. In this way, the light emitted by the light emitting member 210 can directly irradiate the illumination area 130 in the air duct 110 after penetrating the light-transmitting part 180, so as to achieve the purpose of forming a light effect in the illumination area 130.

[0064] It should be noted that the light-transmitting part 180 can be a single light-transmitting plate structure or a composite light-transmitting plate structure, and the present disclosure does not make specific limitations on such transformation modes, and those skilled in the art can adaptively design according to actual application requirements. In addition, the transparent ABS plate can be obtained by adjusting the components of a commonly known ABS plate in the art to achieve a transparent effect, and the present disclosure does not make specific limitations thereon, and the purpose is to be able to achieve the light-transmitting effect through the transparent ABS plate.

[0065] In addition, in some embodiments, the air duct wall plate 170 can be, for example, any suitable engineering plastic plate known in the art, for example, it can be a common ABS [a copolymer of acrylonitrile (Acrylonitrile), butadiene (Butadiene) and styrene (Styrene)] plate or it can also be, for example, a PP-GF20 (a composite material mixed with 20% glass fiber reinforced material) plate, and the present disclosure does not make specific limitations thereon. In order to ensure that the illumination area 130 forms a better light effect, it is necessary to ensure that the surface of the air duct wall plate 170 has a high glossiness to improve the reflection effect of the air duct wall plate 170 and improve the light effect atmosphere and space sense at the first air outlet 120.

[0066] In some embodiments, the light emitting assembly 2 can be configured such that the light effect of the light irradiating onto the illumination area 130 includes an image effect, for example, the light can be imaged on the illumination area 130. In this way, the image effect can include, but is not limited to, for example, a light color or a combination of different light colors, or it can also be, for example, a light curtain effect, so as to be able to improve the light effect atmosphere and space sense at the first air outlet 120.

[0067] In addition, in order to facilitate the switching and design of different light effects, in some embodiments, as shown in Figures 3 to 6 The light emitting assembly 2 can include an imaging member 220 arranged on the light emitting path of the light emitting member 210, so that the light emitted by the light emitting member 210 passes through the imaging member 220 and is irradiated on the light irradiation area 130. In this way, the first air inlet 120 can be freely switched among different light effects by arranging imaging members 220 with different structures, which can improve the light effect atmosphere and space sense at the first air inlet 120, and help improve the aesthetics and user experience of the air conditioner.

[0068] Alternatively, in some alternative embodiments, the light emitting assembly 2 can also be configured such that the light effect of the light irradiated on the light irradiation area 130 can include a dynamic effect. For example, the image formed after the light irradiated on the light irradiation area 130 can present a dynamic light curtain effect, which can include but is not limited to light effects such as light color change, brightness change, flicker or irradiation position change, etc. This helps improve the light effect atmosphere and space sense at the first air inlet 120, and improve the aesthetics and user experience of the air conditioner.

[0069] In addition, in order to facilitate the presentation of the above-mentioned dynamic effect, in some embodiments, as shown in Figures 3 to 6 The light emitting assembly 2 can include an imaging member 220 and a first driving mechanism 230 drivingly connected with the imaging member 220 for driving the imaging member 220 to move. The imaging member 220 is arranged on the light emitting path of the light emitting member 210, so that the light emitted by the light emitting member 210 passes through the imaging member 220 and is irradiated on the light irradiation area 130, thereby facilitating the presentation of the above-mentioned dynamic effect, such as the generation of a dynamic water flow effect or other dynamic image effect. The overall structure is simple and easy to install.

[0070] The imaging member 220 can be configured in any suitable manner, and the purpose is to enable the light to be irradiated on the light irradiation area 130 via the imaging member 220 to form an image effect (which can be a static image effect or a dynamic image effect). For example, in some embodiments, as shown in Figures 3 to 6As shown, the imaging member 220 can include an imaging cylinder 221, the first driving mechanism 230 is used to drive the imaging cylinder 221 to rotate, and the imaging cylinder 221 includes a texture structure 2212 arranged on the outer peripheral wall of the imaging cylinder 221. For example, the imaging cylinder 221 can be a light-transmitting roller 2211, and the corresponding texture structure 2212 is arranged on the outer peripheral wall of the light-transmitting roller 2211. In this way, by arranging different styles of texture structures 2212 on the outer peripheral wall of the light-transmitting roller 2211, the purpose of being able to form different image effects after the light emitted by the light-emitting member 210 is irradiated on the light-irradiation area 130 via the imaging cylinder 221 can be achieved, and the structure is simple and convenient to install and manufacture.

[0071] It can be understood that the specific embodiment of the imaging member 220 including the light-transmitting roller 2211 is exemplary. For example, in other alternative embodiments, the imaging member 220 can also include a light-transmitting member with other shapes, or the imaging member 220 can also include a light-reflecting member, such as a light-reflecting prism, to achieve the purpose of being able to form different image effects after the light emitted by the light-emitting member 210 is irradiated on the light-irradiation area 130 via the imaging member 220.

[0072] In addition, the texture structure 2212 can include grooves and / or protrusions, and the disclosure does not make specific limitations on such transformation modes, and the purpose is to be able to achieve the purpose of being able to form different image effects after the light emitted by the light-emitting member 210 is irradiated on the light-irradiation area 130 via the imaging member 220. For example, the texture structure 2212 can include Figure 8 and / or Figure 9 The groove structure shown, but not limited thereto.

[0073] In addition, it can be understood that the light-transmitting roller 2211 and other light-transmitting members can be made of any suitable light-transmitting material in the art, for example, the light-transmitting roller 2211 can be made of high-transmittance PC material (polycarbonate material). Since the high-transmittance PC material has good light-transmitting effect and structural strength, it can ensure that a good light effect can be stably formed at the light-irradiation area 130, improve the light effect atmosphere and spatial sense at the first air inlet 120, and help improve the aesthetics and user experience of the air conditioner. In addition, it can be understood that in order to ensure that the first air inlet 120 has a high light effect atmosphere and spatial sense, it is necessary to ensure that the surface of the light-transmitting roller 2211 has a high glossiness to increase the light effect and light uniformity.

[0074] It can be understood that the shape of the light-transmitting roller 2211 can include but is not limited to, for example, a cylindrical roller. For example, in other embodiments not shown, the light-transmitting roller 2211 can also be a roller structure of other polygonal cross sections, and the present disclosure does not make specific limitations thereto.

[0076] In addition, in some embodiments, referring to Figures 3 to 6 As shown, the shell 260 can be provided with a light-emitting hole 262 which is in communication with the mounting cavity 261 and is located between the light-emitting element 212 and the imaging member 220, so as to realize the irradiation of the light emitted by the light-emitting member 210 on the outer peripheral wall of the imaging member 220, which is simple in structure and convenient to install and manufacture.

[0078] In addition, it can be understood that, in the case where the shell 260 is configured to be, for example, non-light-transmitting, the light emitted by the light-emitting member 210 can be irradiated on the outer peripheral wall of the imaging member 220 through the light-emitting hole 262, and the light can be irradiated on the light-illuminating area 130 through the imaging member 220 to form an image effect and then be emitted out through the first air outlet 120, so that the first air outlet 120 can present different light effects, which can reduce visual fatigue.

[0079] In addition, as Figure 3 and Figure 6As shown, the above-mentioned housing 260 can include a second shell 263 with a mounting cavity 261 and two support columns 264 connected to the bottom wall of the second shell 263, and one side of the second shell 263 has a baffle 265 extending to the side wall surface of the two support columns 264, so that after the housing 260 is connected to the air duct structure 1, the second shell 263, the two support columns 264, the baffle 265 and the light-transmitting part 180 of the air duct structure 1 can jointly form the above-mentioned containing cavity 270, wherein the imaging member 220 is arranged in the containing cavity 270 and can be rotatably connected to the two support columns 264, so as to realize the dynamic image effect of the dynamic light curtain effect at the light illumination area 130, which helps to improve the light effect atmosphere and space sense at the first air outlet 120.

[0081] In addition, it should be noted that the specific structure of the first transmission connection structure 232 between the driving motor 231 and the imaging cylinder 221 is not limited in the present disclosure, and the purpose is to realize the stable transmission connection of the driving motor 231 to the imaging cylinder 221, and those skilled in the art can adaptively design according to the actual application requirements.

[0084] In addition, it can be understood that when the above-mentioned light emitting element 212 is arranged in multiple, the lamp cup 240 can also be arranged in multiple and one-to-one corresponding to the multiple light emitting elements 212, that is, it can be understood that each lamp cup 240 is arranged around the corresponding light emitting element 212 (for example, a lamp bead) and located between the circuit board 211 and the imaging piece 220, so that the image clarity of the image effect formed at the illumination area 130 can be improved, and the light effect at the first air inlet 120 can be improved.

[0085] In addition, as shown in the figure, Figures 4 to 6 As shown, the lamp cup 240 can include a barrel 241 disposed in the mounting cavity 261 and connected to the second shell 263 at one end and connected to the circuit board 211 at the other end, and the inside of the barrel 241 is provided with a light outlet channel 242, the inner diameter of the light outlet channel 242 gradually increases from the light emitting element 212 to the imaging piece 220, that is, it can be understood that the one end of the barrel 241 connected to the circuit board 211 is formed with a light inlet hole communicated with the light outlet channel 242, and the one end of the barrel 241 connected to the second shell 263 is formed with the above-mentioned light outlet hole 262 communicated with the light outlet channel 242 and the imaging piece 220, so that through the arrangement of the barrel 241, the light emitted by the light emitting element 212 can be converged, achieving the effect of light condensation, while ensuring that the light at the light outlet hole 262 has a larger range of divergence angle, improving the light uniformity at the light transmission part 180, and helping to improve the light uniformity at the first air inlet 120.

[0086] In addition, in some embodiments, the lens assembly 250 is arranged in the lamp cup 240, and the lens assembly 250 is located between the light emitting element 212 and the imaging element 220, that is, the lens assembly 250 can be arranged in the light outlet channel 242 of the lamp cup 240, so that the lens assembly 250 can be installed and fixed through the lamp cup 240, and higher light beam quality and energy density can be obtained through the arrangement of the lens assembly 250, which helps to improve the image clarity of the image effect formed at the light illumination area 130 and improve the lighting effect at the first air inlet 120.

[0087] In the present disclosure, the specific structure of the lens assembly 250 and the specific arrangement number of the lenses are not limited, and those skilled in the art can adaptively design according to the actual application requirements.

[0089] Optionally, in some embodiments, referring to Figure 2 and Figure 3 The air duct structure 1 can further include a shielding assembly 190 arranged at the first air inlet 120, and the shielding assembly 190 includes a plurality of guide plates 191, and the plurality of guide plates 191 have an opening state for opening the first air inlet 120 and a closing state for closing the first air inlet 120. In the opening state, at least part of the light passing through the light illumination area 130 can be observed through the gap between the plurality of guide plates 191 outside the shielding assembly 190. Therefore, when the plurality of guide plates 191 are in the opening state, the lighting effect formed at the light illumination area 130 can be presented through the first air inlet 120, which helps to improve the lighting atmosphere at the first air inlet 120. In addition, due to the arrangement of the guide plates 191, the wind direction at the first air inlet 120 can be adjusted by adjusting the opening angle of the guide plates 191 when the guide plates 191 are in the opening state, and the airflow in the air duct 110 can be smoothly discharged, which can reduce the noise during the operation of the air conditioner.

[0090] In addition, it can be understood that when the above-mentioned flow guide plate 191 is adjusted to, for example, a closed state, it can also play a dustproof effect on the air duct 110, and when the flow guide plate 191 is adjusted to, for example, a closed state, the flow guide plate 191 can be made of, for example, a light-transmitting material, so that even if the flow guide plate 191 is in a closed state, the light effect formed in the illumination area 130 can still be presented at the first air inlet 120, improving the light effect atmosphere of the first air inlet 120. The present disclosure is not limited to this.

[0091] Exemplarily, in some embodiments, with reference to Figure 2 and Figure 3 As shown, the shielding assembly 190 can include a second driving mechanism 192 drivingly connected with the plurality of flow guide plates 191 to drive the plurality of flow guide plates 191 to switch between the open state and the closed state. The second driving mechanism 192 is located between the first air inlet 120 and the light-emitting assembly 2. Exemplarily, the air duct structure 1 includes a first plate body 171 including a first plate portion 1711, a light-transmitting portion 180, and a second plate portion 1712 connected in sequence. The extension directions of the first plate portion 1711 and the second plate portion 1712 form an included angle. The first air inlet 120 is located at one end of the second plate portion 1712 away from the first plate portion 1711. The second driving mechanism 192 is arranged on the outer wall surface of the second plate portion 1712. In this way, the light-emitting assembly 2 is arranged between the first plate body 171 and the second driving mechanism 192, and emits light to the illumination area 130 through the light-transmitting portion 180. That is, the second driving mechanism 192 is located between the first air inlet 120 and the light-emitting assembly 2. In this way, the light effect formed in the illumination area 130 can be presented at the first air inlet 120, and the overall structure of the air duct device is compact, providing more design space for the design of, for example, an air conditioner. By arranging the light-emitting assembly 2 between the first plate body 171 and the second driving mechanism 192 and emitting light to the illumination area 130 through the light-transmitting portion 180, the path of the light is short, energy loss is reduced, and the light irradiated into the illumination area 130 forms a good light effect in the illumination area 130.

[0092] Wherein, the present disclosure does not make specific limitation on the specific connection structure of the second driving mechanism 192 and the plurality of flow guide plates 191, and those skilled in the art can adaptively design the second transmission connection structure (not shown) between the second driving mechanism 192 and the plurality of flow guide plates 191 according to the actual application requirements, for example, the second driving mechanism 192 can include a motor, and the corresponding second transmission connection structure can include a gear transmission structure or a connecting rod mechanism transmission structure, etc., the purpose is to be able to realize the second driving mechanism 192 driving the plurality of flow guide plates 191 to switch between the open state and the closed state.

In addition, the indoor unit has all the beneficial effects of the air duct device provided in the first aspect, which will not be described here again.

Since the air outlet passage is arranged in communication with the second air outlet 140 of the air duct 110 of the air duct structure 1, the air flow in the air conditioner can be made to pass through the air outlet passage and be discharged to the outside of the first shell 3 through the opening at the bottom end of the first shell 3 in communication with the first air outlet 120 of the air duct 110 of the air duct structure 1 along the extension direction of the air duct 110 of the air duct structure 1, so as to achieve air outlet of the air conditioner.
