[0002] In the related art, the light of an air conditioner usually emits light directly. However, in this form, the lamp structure and its related installation structure can be seen from the outside of the air conditioner, which affects the aesthetics of the air conditioner and makes the external structure design of the air conditioner more complex. At the same time, there is a problem of poor lighting effect. Summary of the Invention

[0003] The purpose of the present disclosure is to provide an air duct device, an indoor unit, and an air conditioner, which can solve the problems of complex external structure design and poor lighting effect in the related art, and improve the lighting effect atmosphere and user experience of the air conditioner.

[0004] To achieve the above object, a first aspect of the present disclosure provides an air duct device, which includes: an air duct structure having an air duct and a first air outlet communicating with the air duct, and a lighting area is provided on the inner wall surface of the air duct structure surrounding the air duct; and a light-emitting assembly connected to the air duct structure and including a light-emitting member for emitting light to the lighting area so that at least part of the light passing through the lighting area can be observed through the first air outlet outside the first air outlet. Such an arrangement can solve the problems of complex external structure design and poor lighting effect in the related art, and improve the lighting effect atmosphere and user experience of the air conditioner.

[0005] In some possible embodiments, the position of the lighting area relative to the first air outlet is arranged such that at least part of the light is reflected by the lighting area and then emitted through the first air outlet, so as to facilitate observing the light on the lighting area through the first air outlet.

[0006] In some possible embodiments, the inner wall surface of the air duct structure has a turning portion, the lighting area is located on the turning portion, and the projection of the turning portion in a direction perpendicular to the plane defined by the first air outlet is at least partially located within the first air outlet, so that the light reflected by the lighting area is emitted through the first air outlet, so as to facilitate emitting the light of the light-emitting member through the lighting area and then through the first air outlet.

[0007] In some possible embodiments, the turning portion includes a curved surface portion and / or a flat surface portion, so as to facilitate emitting the light of the light-emitting member through the lighting area and then through the first air outlet.

[0008] In some possible embodiments, the air duct structure includes an air duct wall panel that encloses the air duct and the first air outlet. The air duct wall panel has a light-transmitting portion and the illumination area. The light-emitting component is disposed on a side of the light-transmitting portion facing away from the interior of the air duct to emit the light to the illumination area through the light-transmitting portion. With such an arrangement, while the light irradiated into the illumination area forms, for example, a lighting effect in the illumination area, since the light-emitting component is located outside the air duct of the air duct structure, the light-emitting component does not occupy the interior space of the air duct, ensuring that the air duct structure has a good air outlet effect and air supply efficiency, which helps to improve the overall performance of the air conditioner.

[0009] In some possible embodiments, the air duct wall panel includes a first plate body and a second plate body arranged opposite to each other. One of the first plate body and the second plate body is provided with the light-transmitting portion, and the other has the illumination area. With such an arrangement, it is convenient for the light emitted by the light-emitting member disposed on a side of the light-transmitting portion facing away from the interior of the air duct to directly irradiate the illumination area in the air duct through the light-transmitting portion, enabling the light path to be shorter, reducing energy loss, ensuring that the light irradiated into the illumination area forms a good lighting effect in the illumination area, and improving the lighting effect atmosphere and sense of space at the first air outlet.

[0010] In some possible embodiments, the first plate body is located above the second plate body. The first plate body is provided with the light-transmitting portion, and the second plate body has the illumination area. With such an arrangement, it is convenient to enable the light emitted by the light-emitting member disposed on a side of the light-transmitting portion facing away from the interior of the air duct to directly irradiate the illumination area in the air duct through the light-transmitting portion and form a good lighting effect in the illumination area.

[0011] In some possible embodiments, the first plate body includes a first plate portion, the light-transmitting portion, and a second plate portion. The extending directions of the first plate portion and the second plate portion form an angle, and the light-transmitting portion is connected between the first plate portion and the second plate portion. With such an arrangement, it is convenient to enable the light emitted by the light-emitting member disposed on a side of the light-transmitting portion facing away from the interior of the air duct to directly irradiate the illumination area in the air duct through the light-transmitting portion.

[0012] In some possible embodiments, the second plate body includes a third plate portion, a fourth plate portion, and a fifth plate portion that are sequentially connected. The extending directions of the third plate portion and the fifth plate portion form an angle. The illumination area is provided on the fourth plate portion. The light-transmitting portion is configured as a curved plate body or a flat plate body that protrudes toward the illumination area. Such an arrangement facilitates the light emitted by the light-emitting member disposed on the side of the light-transmitting portion facing away from the inside of the air duct to directly irradiate the illumination area in the air duct through the light-transmitting portion, enabling the light path to be shorter, reducing energy loss, ensuring that the light irradiated into the illumination area forms a good lighting effect in the illumination area, and enhancing the lighting effect atmosphere and sense of space at the first air outlet.

[0013] In some possible embodiments, the light-transmitting portion includes at least one of a transparent ABS plate, a light-transmitting polycarbonate plate, an acrylic plate, or a glass plate. Such an arrangement facilitates the light emitted by the light-emitting member to directly irradiate the illumination area in the air duct through the light-transmitting portion, achieving the purpose of forming a lighting effect in the illumination area.

[0014] In some possible embodiments, the light-emitting assembly is configured such that the light effect of the light irradiated onto the illumination area includes an image effect. Such an arrangement can enhance the lighting effect atmosphere and sense of space at the first air outlet.

[0015] In some possible embodiments, the light-emitting assembly includes an imaging member. The imaging member is disposed on the light-emitting path of the light-emitting member so that the light emitted by the light-emitting member irradiates onto the illumination area after passing through the imaging member. Such an arrangement achieves the purpose of forming a light effect in the illumination area.

[0016] In some possible embodiments, the light-emitting assembly is configured such that the light effect of the light irradiated onto the illumination area includes a dynamic effect. Such an arrangement can enhance the lighting effect atmosphere and sense of space at the first air outlet.

[0017] In some possible embodiments, the light-emitting assembly includes an imaging member and a first driving mechanism. The first driving mechanism is drivingly connected to the imaging member to drive the imaging member to move. The imaging member is disposed on the light-emitting path of the light-emitting member so that the light emitted by the light-emitting member irradiates onto the illumination area via the imaging member to present the dynamic effect. Such an arrangement achieves the purpose of enhancing the lighting effect atmosphere and sense of space at the first air outlet.

[0018] In some possible embodiments, the imaging member includes an imaging cylinder, and the first driving mechanism is configured to drive the imaging cylinder to rotate. The imaging cylinder includes a texture structure provided on the outer peripheral wall thereof. With such an arrangement, by providing different styles of texture structures on the outer peripheral wall of the imaging cylinder, it is possible to achieve the purpose of forming different image effects after the light emitted by the light-emitting member is irradiated on the illumination area through the imaging cylinder. The structure is simple and convenient for installation and preparation.

[0019] In some possible embodiments, the imaging cylinder is a light-transmitting roller. With such an arrangement, it is convenient to achieve the formation of different image effects after the light emitted by the light-emitting member is irradiated on the illumination area through the imaging cylinder.

[0020] In some possible embodiments, the texture structure includes grooves and / or protrusions. With such an arrangement, the purpose of forming different image effects can be achieved. The structure is simple and convenient for installation and preparation.

[0021] In some possible embodiments, the light-emitting member includes a circuit board and a light-emitting element provided on the circuit board. The light-emitting assembly further includes a lamp cup. The lamp cup is arranged around the light-emitting element and is located between the circuit board and the imaging member. With such an arrangement, through the setting of the lamp cup, the convergence of the light emitted by the light-emitting element can be realized, achieving a light-concentrating effect, so that the light emitted after being concentrated by the lamp cup irradiates the outer peripheral wall of the imaging member, and after the light irradiates the illumination area through the imaging member, it can be ensured that a relatively clear image effect can be formed at the illumination area, ensuring a high lighting effect at the first air outlet.

[0022] In some possible embodiments, a lens assembly is provided in the lamp cup. The lens assembly is located between the light-emitting element and the imaging member. With such an arrangement, higher beam quality and energy density can also be obtained through the setting of the lens assembly, which helps to improve the image clarity of the image effect formed at the illumination area and enhance the lighting effect at the first air outlet.

[0023] In some possible embodiments, the air duct structure includes a light-transmitting portion. The light-emitting assembly is provided on a side of the light-transmitting portion facing away from the inside of the air duct to emit the light to the illumination area through the light-transmitting portion. The light-emitting assembly further includes a housing. The housing and the light-transmitting portion define an accommodation cavity. The imaging member is provided in the accommodation cavity and is connected to the housing. The housing has an installation cavity, and the light-emitting member is provided in the installation cavity. With such an arrangement, it is possible to hide the light-emitting member, for example, and avoid directly exposing the light-emitting member, so as to improve the aesthetics of, for example, an air conditioner.

[0024] In some possible embodiments, a light-emitting hole communicating with the installation cavity and located between the light-emitting element and the imaging element is provided on the outer shell. Such an arrangement facilitates the light emitted by the light-emitting element to irradiate on the outer peripheral wall of the imaging element.

[0025] In some possible embodiments, the air duct structure further includes a shielding component disposed at the first air outlet. The shielding component includes a plurality of flow guiding plates. The plurality of flow guiding plates have an open state for opening the first air outlet and a closed state for closing the first air outlet. In the open state, at least part of the light passing through the illumination area can be observed through the gaps between the plurality of flow guiding plates from outside the shielding component. Such an arrangement can improve the lighting effect and atmosphere at the first air outlet. And due to the setting of the flow guiding plates, when the flow guiding plates are in the open state, the wind direction at the first air outlet can be adjusted by adjusting the opening angle of the flow guiding plates. At the same time, the air flow in the air duct can be discharged smoothly, and the noise during the operation of, for example, an air conditioner can be reduced.

[0026] In some possible embodiments, the shielding component includes a second driving mechanism. The second driving mechanism is drivingly connected to the plurality of flow guiding plates to drive the plurality of flow guiding plates to switch between the open state and the closed state. The second driving mechanism is located between the first air outlet and the light-emitting component. Such an arrangement can make the overall structure of the air duct device more compact, providing a larger design space for the design of, for example, an air conditioner.

[0027] A second aspect of the present disclosure provides an indoor unit, which includes the air duct device provided in the first aspect and a first housing. The first housing has an inner cavity for installing the air duct device and an opening for communicating the first air outlet with the outside.

[0028] In some possible embodiments, the opening is provided on the outer side wall of the first housing and adjacent to the bottom end of the first housing. Such an arrangement facilitates improving the energy efficiency of, for example, an air conditioner and reducing the accumulation of dust at the opening.

[0029] A third aspect of the present disclosure provides an air conditioner, which includes the indoor unit provided in the second aspect.

[0030] Through the above technical solution, that is, the air duct device provided by the present disclosure, the air duct device uses a light-emitting component connected to the air duct structure to emit light to an illuminated area on the inner wall surface of the air duct surrounded by the air duct structure, so that at least part of the light passing through the illuminated area can be observed through the first air outlet outside the first air outlet. With such an arrangement, when a lighting effect, for example, is presented in the illuminated area irradiated by the light-emitting component, the lighting effect atmosphere at the first air outlet can be improved, and by adaptively adjusting, for example, the lighting effect of the light-emitting component, free switching between different lighting effects can also be achieved, which helps to improve the aesthetics and user experience of, for example, an air conditioner. In addition, since the light on the illuminated area can be observed through the first air outlet, for example, the light effects such as a lighting effect presented in the illuminated area irradiated by the light-emitting component can be observed through the first air outlet. Compared with the related art in which the lamp structure is directly exposed outside the air conditioner and the light directly shines into the human eyes, the lighting effect provided by the present disclosure is relatively soft, which can reduce visual fatigue, and the light-emitting component can also be arranged in a hidden manner, avoiding the direct exposure arrangement of the lamp structure in the related art. Thus, after the light-emitting component is arranged in a hidden manner in the present disclosure, the external structure of, for example, an air conditioner can be simplified, which helps to improve the aesthetics of, for example, an air conditioner, and can reduce the possibility of dust accumulation on the surface area of the light-emitting component, enhancing the lighting effect atmosphere and lighting effect at the first air outlet.

Detailed description of the specific embodiment

[0034] The following will describe the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present disclosure, and are not intended to limit the present disclosure.

[0035] In the present disclosure, unless otherwise stated, the orientation terms such as "upper, lower" generally refer to the upper and lower in the space when the air conditioner is in use. "Inner, outer" refer to the inner and outer relative to the contour of the component or structure itself. In addition, it should be noted that the terms such as "first, second" are used to distinguish one element from another, and do not have sequentiality and importance. In addition, in the description with reference to the accompanying drawings, the same reference numerals in different drawings represent the same elements.

[0036] According to a first aspect of the present disclosure, there is provided an air duct device, refer to Figures 1 to 9As shown in the figure, the air duct device includes an air duct structure 1 and a light-emitting component 2. The air duct structure 1 has an air duct 110 and a first air outlet 120 communicating with the air duct 110. An illumination area 130 is provided on the inner wall surface 150 of the air duct structure 1 that encloses the air duct 110. The light-emitting component 2 is connected to the air duct structure 1 and includes a light-emitting element 210. The light-emitting element 210 is configured to emit light toward the illumination area 130 so that at least part of the light passing through the illumination area 130 can be observed through the first air outlet 120 from outside the first air outlet 120.

[0037] Through the above technical solution, that is, the air duct device provided by the present disclosure, the light-emitting element 210 connected to the air duct structure 1 is configured to emit light toward the illumination area 130 on the inner wall surface 150 of the air duct structure 1 that encloses the air duct 110, so that at least part of the light passing through the illumination area 130 can be observed through the first air outlet 120 from outside the first air outlet 120. With such an arrangement, when the illumination area 130 irradiated by the light-emitting element 210 presents a lighting effect, for example, the lighting effect atmosphere at the first air outlet 120 can be improved, and by adaptively adjusting the lighting effect of the light-emitting element 210, for example, the free switching of different lighting effects can also be achieved, which helps to improve the aesthetics and user experience of, for example, an air conditioner.

[0038] In addition, since the light on the illumination area 130 can be observed through the first air outlet 120, for example, the light effect such as a lighting effect presented on the illumination area 130 irradiated by the light-emitting element 210 can be observed through the first air outlet 120. Compared with the prior art in which the lamp structure is directly exposed outside the air conditioner and the light directly shines into the human eye, the light effect provided by the present disclosure is relatively soft, which can reduce visual fatigue, and the light-emitting element 210 can also be arranged in a hidden manner, avoiding the direct exposure arrangement of the lamp structure in the prior art. Thus, after the light-emitting element 210 is arranged in a hidden manner, the present disclosure can simplify the external structure of, for example, an air conditioner, which helps to improve the aesthetics of, for example, an air conditioner, and can reduce the possibility of dust accumulation on the surface area of the light-emitting element 210, enhancing the lighting effect atmosphere and light effect at the first air outlet 120.

[0039] Among them, it should be noted that when a light effect such as a lighting effect is presented in the illuminated area 130 irradiated by the light-emitting member 210, the above light effect can be an effect generated after the light irradiates the illuminated area 130. For example, it can present a lighting color or a combination of different lighting colors and other lighting effects. And it can be understood that the image formed after the light irradiates the illuminated area 130 can present, for example, different light curtain effects, and the light curtain effect can include but is not limited to light effects such as lighting color change, brightness change, flicker or irradiation position change, etc. The present disclosure does not make specific limitations thereon. The purpose is to be able to improve the lighting effect atmosphere at the first air outlet 120, and it is sufficient to achieve the purpose of improving the aesthetics and user experience of, for example, an air conditioner.

[0040] In some embodiments, referring to Figures 3 to 5 As shown, the illuminated area 130 can be arranged relative to the position of the first air outlet 120 such that at least part of the light is reflected by the illuminated area 130 and then emitted through the first air outlet 120. Such an arrangement is for facilitating observing the light on the illuminated area 130 through the first air outlet 120, and by emitting the lighting effect at the illuminated area 130 through the first air outlet 120, it can also improve the lighting effect atmosphere and sense of space at the first air outlet 120.

[0041] In some embodiments, referring to Figures 3 to 5 As shown, the air duct structure 1 can have a second air outlet 140 communicating with the air duct 110. The inner wall surface 150 of the air duct structure 1 has a turning portion 160 such that the air duct 110 turns at least partially between the first air outlet 120 and the second air outlet 140. The illuminated area 130 is located on the turning portion 160, and the projection of the turning portion 160 in the direction perpendicular to the plane defined by the first air outlet 120 is at least partially located within the first air outlet 120, so that the light reflected by the illuminated area 130 is emitted through the first air outlet 120. Such an arrangement can achieve emitting the lighting effect at the illuminated area 130 through the first air outlet 120 while also facilitating adaptively adjusting the air outlet direction of the air duct 110.

[0042] Among them, as Figures 3 to 5 shown, the turning portion 160 can include a curved surface portion, that is, it can be understood that the inner wall surface 150 of the air duct structure 1 can 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, through the setting of the curved surface portion, the turbulence and impact of the air flow in the air duct 110 can be reduced, the air flow resistance can be reduced, which helps to reduce the operating noise and improve the air supply efficiency.

[0043] In addition, in some alternative embodiments not shown, 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, an inclined surface, which can cause the air duct 110 to extend at least partially obliquely between the first air outlet 120 and the second air outlet 140. Alternatively, in some alternative embodiments not shown, the turning portion 160 may also include both the above-mentioned curved surface portion and the planar portion. The present disclosure does not specifically limit such deformation modes, and those skilled in the art can adaptively design according to actual application requirements.

[0044] In addition, in some embodiments, referring to Figures 3 to 5 as shown, the air duct structure 1 may include an air duct wall plate 170. The air duct wall plate 170 encloses the air duct 110, the first air outlet 120, and the second air outlet 140. The air duct wall plate 170 has a light-transmitting portion 180 and a lighting area 130. The light-emitting component 2 is disposed on the side of the light-transmitting portion 180 facing away from the inside of the air duct 110 to emit light to the lighting area 130 through the light-transmitting portion 180. That is, it can be understood that by disposing 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 member 210 pass through the light-transmitting portion 180 and then irradiate the lighting area 130 inside the air duct 110. With such an arrangement, while the light irradiated into the lighting area 130 forms, for example, a lighting effect in the lighting area 130, since the light-emitting component 2 is located outside the air duct 110 of the air duct structure 1, it also avoids the light-emitting component 2 occupying the internal space of the air duct 110, 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.

[0045] Among them, as Figures 3 to 5 shown, the air duct wall plate 170 may include a first plate body 171 and a second plate body 172 arranged opposite to each other. One of the first plate body 171 and the second plate body 172 is provided with the light-transmitting portion 180, and the other has the lighting area 130 (the lighting area 130 is located on the turning portion 160). With such an arrangement, it is convenient for the light emitted by the light-emitting member 210 disposed on the side of the light-transmitting portion 180 facing away from the inside of the air duct 110 to pass through the light-transmitting portion 180 and directly irradiate the lighting area 130 inside the air duct 110, which can make the path of the light shorter, reduce energy loss, ensure that the light irradiated into the lighting area 130 forms a good lighting effect in the lighting area 130, and improve the lighting effect atmosphere and sense of space at the first air outlet 120.

[0046] Exemplarily, in some embodiments, referring to Figures 3 to 5As shown, the first plate body 171 can be located above the second plate body 172. The first plate body 171 is provided with a light-transmitting portion 180, and the second plate body 172 has a lighting area 130. Such an arrangement is to facilitate enabling the light emitted by the light-emitting member 210 disposed on the side of the light-transmitting portion 180 facing away from the inside of the air duct 110 to directly irradiate the lighting area 130 in the air duct 110 through the light-transmitting portion 180, and a good lighting effect can be formed in the lighting area 130.

[0047] It can be understood that the above specific embodiment in which the first plate body 171 can be located above the second plate body 172, the first plate body 171 is provided with the light-transmitting portion 180, and the second plate body 172 has the lighting area 130 is exemplary. In some other alternative embodiments not shown, the first plate body 171 can also be located below the second plate body 172, the first plate body 171 is provided with the light-transmitting portion 180, and the second plate body 172 has the lighting area 130. The present disclosure is not limited thereto either. The purpose is to enable the light emitted by the light-emitting member 210 to directly irradiate the lighting area 130 in the air duct 110 through the light-transmitting portion 180, and a good lighting effect can be formed in the lighting area 130. Those skilled in the art can design adaptively according to actual application requirements.

[0048] In addition, in some embodiments, referring to Figures 3 to 5 As shown, the first plate body 171 can include a first plate portion 1711, a light-transmitting portion 180, and a second plate portion 1712. The extending directions of the first plate portion 1711 and the second plate portion 1712 form an angle. 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 can include a third plate portion 1721, a fourth plate portion 1722, and a fifth plate portion 1723 that are sequentially connected. The extending directions of the third plate portion 1721 and the fifth plate portion 1723 form an angle. The lighting area 130 is provided on the fourth plate portion 1722. The light-transmitting portion 180 is configured as a curved plate body or a flat plate body protruding toward the lighting area 130. Such an arrangement facilitates enabling the light emitted by the light-emitting member 210 disposed on the side of the light-transmitting portion 180 facing away from the inside of the air duct 110 to directly irradiate the lighting area 130 (i.e., the lighting area 130 on the fourth plate portion 1722) in the air duct 110 through the light-transmitting portion 180, enabling the path that the light passes through to be shorter, reducing energy loss, ensuring that the light irradiated into the lighting area 130 forms a good lighting effect in the lighting area 130, and improving the lighting effect atmosphere and sense of space at the first air outlet 120.

[0049] It can be understood that, by arranging the extending directions of the first plate portion 1711 and the second plate portion 1712 at an angle, and arranging the extending directions of the third plate portion 1721 and the fifth plate portion 1723 at an angle, it is also possible to adaptively change the angle value of the corresponding angle according to the air supply direction of the air duct 110 to change the orientation direction of the first air outlet 120 of the air duct 110, thereby improving the applicability of, for example, an air conditioner. Among them, the present disclosure does not specifically limit the angle value of the specific angle formed by the extending directions of the above-mentioned first plate portion 1711 and the second plate portion 1712, nor the angle value of the specific angle formed by the extending directions of the third plate portion 1721 and the fifth plate portion 1723. Those skilled in the art can adaptively design according to actual application requirements.

[0050] In addition, it should be noted that the present disclosure does not specifically limit the specific connection manner of the above-mentioned first plate portion 1711, the light-transmitting portion 180, and the second plate portion 1712. Those skilled in the art can adaptively design according to actual application requirements. For example, the above-mentioned first plate body 171 may include a first plate portion 1711, a light-transmitting portion 180, and a second plate portion 1712 that are connected in sequence. And in order to ensure a good sealing effect at the connection, the corresponding connection position can be sealed and connected by, for example, adhesive, so as to ensure that the first plate body 171 has a high structural strength and at the same time ensure that the air duct 110 has a high sealing performance. Alternatively, the above-mentioned first plate body 171 may also include a connected first plate portion 1711 and a second plate portion 1712, and an installation 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, and the light-transmitting plate is sealingly connected to the installation opening. For example, the light-transmitting plate can be sealingly attached to the first plate portion 1711 and the second plate portion 1712 and cover the installation opening. The present disclosure is not limited thereto. The purpose is to be able to ensure that the first plate body 171 has a high structural strength and at the same time ensure that the air duct 110 has a high sealing performance. Those skilled in the art can adaptively design according to actual application requirements.

[0051] In addition, the present disclosure does not specifically limit the specific connection manner of the above-mentioned third plate portion 1721, the fourth plate portion 1722, and the fifth plate portion 1723. Those skilled in the art can adaptively design according to actual application requirements. For example, the above-mentioned third plate portion 1721, the fourth plate portion 1722, and the fifth plate portion 1723 can be integrally formed or can also be assembled and connected. The purpose is to be able to ensure that the second plate body 172 has a high structural strength and at the same time ensure that the air duct 110 has a high sealing performance.

[0052] In addition, in some embodiments, refer to Figures 3 to 5As shown, the air duct wall panel 170 may include two side panels 173 arranged opposite to each other. The two side panels 173 are connected between the first plate body 171 and the second plate body 172. The first plate body 171, the second plate body 172 and the two side panels 173 together enclose the air duct 110, the first air outlet 120 and the second air outlet 140. Such an arrangement ensures that the air duct 110 of the air duct structure 1 can supply air stably, while the overall structure arrangement is relatively simple and convenient for installation and preparation.

[0053] 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 passing through the light-transmitting portion 180, in some embodiments, the light-transmitting portion 180 may include at least one of a transparent ABS board, a light-transmitting polycarbonate board, an acrylic board or a glass board. Such an arrangement facilitates the light emitted by the light-emitting member 210 to directly irradiate the illumination area 130 in the air duct 110 after passing through the light-transmitting portion 180, so as to achieve the purpose of forming a lighting effect in the illumination area 130.

[0054] It should be noted that the above-mentioned light-transmitting portion 180 may be a single light-transmitting board structure or a composite light-transmitting board structure. The present disclosure does not make specific limitations on such deformation methods, and those skilled in the art can adaptively design according to actual application requirements. In addition, the transparent ABS board can achieve the transparent effect by adjusting the components of the common ABS board known in the art. The present disclosure does not make specific limitations on this, and the purpose is to be able to achieve the light-transmitting effect through the transparent ABS board.

[0055] In addition, in some embodiments, the above-mentioned air duct wall panel 170 may be any suitable engineering plastic sheet known in the art, such as a common ABS [copolymerized by three monomers: acrylonitrile, butadiene and styrene)] board or also, for example, a PP-GF20 (a composite material mixed by polypropylene and 20% glass fiber reinforcement material) sheet. The present disclosure does not make specific limitations on this. And, in order to ensure a good lighting effect at the illumination area 130, it is necessary to ensure that the surface of the air duct wall panel 170 has a high gloss to improve the reflection effect of the air duct wall panel 170 and enhance the lighting effect atmosphere and spatial sense at the first air outlet 120.

[0056] In some embodiments, the light-emitting assembly 2 may be configured such that the light effect of the light irradiating on the illumination area 130 includes an image effect. For example, imaging can be performed on the illumination area 130 by using light. In this way, the image effect may include, but is not limited to, lighting effects such as lighting colors or combinations of different lighting colors, or may also be, for example, a light curtain effect, etc., so as to be able to enhance the lighting effect atmosphere and spatial sense at the first air outlet 120.

[0057] In addition, in order to facilitate the switching and design of different lighting effects, in some embodiments, referring to Figures 3 to 6 As shown, the light-emitting component 2 may include an imaging member 220. The imaging member 220 is disposed on the light-emitting path of the light-emitting member 210 so that the light emitted by the light-emitting member 210 irradiates the illumination area 130 after passing through the imaging member 220. With such an arrangement, it is convenient to freely switch different lighting effects at the first air outlet 120 by setting imaging members 220 with different structures, which can improve the lighting atmosphere and sense of space at the first air outlet 120, and contribute to improving the aesthetics and user experience of, for example, an air conditioner. At the same time, the user can also adaptively install imaging members 220 with different structures according to their own needs to achieve the switching of different lighting effects, and the structure is simple and convenient for disassembly, replacement and installation.

[0058] Alternatively, in some alternative embodiments, the light-emitting component 2 can also be configured such that the light effect of the light irradiating the illumination area 130 can include a dynamic effect. For example, the image formed after the light irradiates the illumination area 130 can present, for example, different dynamic light curtain effects, and the light curtain effect can include but is not limited to, for example, light color change, brightness change, flicker or irradiation position change and other light effects, which helps to improve the lighting atmosphere and sense of space at the first air outlet 120, and improve the aesthetics and user experience of, for example, an air conditioner.

[0059] In addition, in order to facilitate the presentation of the above dynamic effect, in some embodiments, referring to Figures 3 to 6 As shown, the light-emitting component 2 may include an imaging member 220 and a first driving mechanism 230. The first driving mechanism 230 is drivingly connected to the imaging member 220 to drive the imaging member 220 to move. The imaging member 220 is disposed on the light-emitting path of the light-emitting member 210 so that the light emitted by the light-emitting member 210 irradiates the illumination area 130 through the imaging member 220, so as to facilitate the presentation of the above dynamic effect, such as generating dynamic image effects such as dynamic water flow effects. The overall structure is simple and convenient for installation and preparation.

[0060] Among them, the imaging member 220 can be constructed in any suitable manner, and its purpose is to enable the light to irradiate the illumination area 130 through the imaging member 220 to form an image effect (the image effect can be, for example, a static image effect or a dynamic image effect). For example, in some embodiments, referring to Figures 3 to 6As shown, the imaging member 220 may include an imaging cylinder 221. The first driving mechanism 230 is used to drive the imaging cylinder 221 to rotate. The imaging cylinder 221 includes a texture structure 2212 provided on the outer peripheral wall of the imaging cylinder 221. Exemplarily, for example, the imaging cylinder 221 may be a light-transmitting roller 2211, and the corresponding texture structure 2212 is provided on the outer peripheral wall of the light-transmitting roller 2211. With such an arrangement, by providing different styles of texture structures 2212 on the outer peripheral wall of the light-transmitting roller 2211, the purpose of forming different image effects after the light emitted by the light-emitting member 210 is irradiated on the illumination area 130 through the imaging cylinder 221 can be achieved. The structure is simple and convenient for installation and preparation.

[0061] It can be understood that the specific embodiment in which the above imaging member 220 may include the light-transmitting roller 2211 is exemplary. For example, in some alternative embodiments, the imaging member 220 may also include, for example, a light-transmitting member with other outer shapes, or the imaging member 220 may also include, for example, a reflective member, such as a reflective prism, to achieve, for example, a rainbow image effect. And the reflective prism may be, for example, a triangular prism or a reflective prism structure with other polygonal profiles. The present disclosure does not make specific limitations thereto. The purpose is to be able to achieve the purpose of forming different image effects after the light emitted by the light-emitting member 210 is irradiated on the illumination area 130 through the imaging member 220.

[0062] In addition, the above texture structure 2212 may include grooves and / or protrusions. The present disclosure does not make specific limitations on such deformation methods. The purpose is to be able to achieve the purpose of forming different image effects after the light emitted by the light-emitting member 210 is irradiated on the illumination area 130 through the imaging member 220. For example, the above texture structure 2212 may include Figure 8 and / or Figure 9 the groove structure shown, but is not limited thereto.

[0063] In addition, it can be understood that the above light-transmitting members such as the light-transmitting roller 2211 may be prepared from any suitable light-transmitting material in the art. For example, the above light-transmitting roller 2211 may be prepared by a high-transparency PC material (polycarbonate material). Since the high-transparency PC material has good light-transmitting effects and structural strength, it can ensure that a better lighting effect can be stably formed at the illumination area 130, improving the lighting effect atmosphere and sense of space at the first air outlet 120, and helping to improve, for example, the aesthetics and user experience of the air conditioner. And it can be understood that, in order to ensure a high lighting effect atmosphere and sense of space at the first air outlet 120, it is necessary to ensure that the surface of the light-transmitting roller 2211 has a high gloss to increase the lighting effect and light output uniformity.

[0064] It can be understood that the external structure of the above-mentioned light-transmitting roller 2211 may include, but is not limited to, for example, a cylindrical roller. For example, in some other embodiments not shown, the light-transmitting roller 2211 may also be a roller structure with a polygonal cross-section. The present disclosure does not make specific limitations thereto.

[0065] Considering that since the air duct structure 1 includes a light-transmitting portion 180 and the light-emitting assembly 2 is disposed on the side of the light-transmitting portion 180 facing away from the inside 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 when the light-emitting assembly 2 is disposed outside the air duct 110 of the air duct structure 1, in order to be able to hide the light-emitting element 210, avoid direct exposure of the light-emitting element 210, and improve the aesthetics of, for example, an air conditioner. Therefore, in some embodiments, referring to Figures 3 to 6 as shown, the light-emitting assembly 2 may further include a housing 260. The housing 260 and the light-transmitting portion 180 enclose a receiving cavity 270. The imaging element 220 is disposed in the receiving cavity 270 and connected to the housing 260. The housing 260 has a mounting cavity 261, and the light-emitting element 210 is disposed in the mounting cavity 261. In this way, through the setting of the housing 260, the structures such as the light-emitting element 210 and the imaging element 220 can be hidden inside the housing 260, which helps to improve the aesthetics of, for example, an air conditioner, and the setting of the housing 260 can also protect the structures such as the light-emitting element 210 and the imaging element 220.

[0066] In addition, in some embodiments, referring to Figures 3 to 6 as shown, the housing 260 may be provided with a light-emitting hole 262 that communicates with the mounting cavity 261 and is located between the light-emitting element 212 and the imaging element 220, so as to facilitate the light emitted by the light-emitting element 210 to irradiate the outer peripheral wall of the imaging element 220. The structure is simple and easy to install and prepare.

[0067] Among them, the present disclosure does not make specific limitations on the specific connection manner between the housing 260 and the air duct structure 1. The purpose is to be able to stably connect the housing 260 to the air duct structure 1, and those skilled in the art can adaptively design according to actual application requirements.

[0068] In addition, it can be understood that when the above-mentioned housing 260 is constructed to be, for example, light-impermeable, the light emitted by the light-emitting element 210 can be irradiated on the outer peripheral wall of the imaging element 220 through the light-emitting hole 262, and the light can be irradiated on the illumination area 130 through the imaging element 220, so as to form an image effect and then be emitted through the first air outlet 120, so that different lighting effects can be presented at the first air outlet 120, which can reduce visual fatigue.

[0069] In addition, as Figure 3 and Figure 6As shown, the above-mentioned housing 260 may include a second housing 263 having an installation cavity 261 and two support columns 264 connected to the bottom wall of the second housing 263, and one side of the second housing 263 has a baffle 265 extending to the side wall surfaces of the two support columns 264. In this way, after connecting the housing 260 to the air duct structure 1, the second housing 263, the two support columns 264, the baffle 265, and the light-transmitting portion 180 of the air duct structure 1 can jointly enclose the above-mentioned accommodation cavity 270. Among them, the imaging member 220 is arranged in the accommodation cavity 270 and can be rotatably connected to the two support columns 264 to achieve a dynamic image effect such as a dynamic light curtain effect at the illumination area 130, which helps to improve the light effect atmosphere and sense of space at the first air outlet 120.

[0070] Among them, as Figure 3 and Figure 6 shown, the first driving mechanism 230 may include at least one driving motor 231. The driving motor 231 may be located outside the accommodation cavity 270 and connected to one of the support columns 264. For example, a receiving groove 266 for receiving the driving motor 231 may be provided on the corresponding support column 264 to achieve the hidden arrangement of the driving motor 231. And the output shaft of the driving motor 231 passes through the support column 264 and is in transmission connection with the imaging cylinder 221 arranged in the accommodation cavity 270 to drive the imaging cylinder 221 to rotate. And it can be understood that by adaptively adjusting the rotation speed of the driving motor 231, different dynamic lighting effects at the first air outlet 120 can be presented.

[0071] 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 specifically limited in this disclosure. The purpose is to be able to stably transmit the driving motor 231 to the imaging cylinder 221. Those skilled in the art can design adaptively according to actual application requirements.

[0072] In addition, in some embodiments, referring to Figure 3 and Figure 6 shown, the housing 260 may further include a cover body 267 connected to the second housing 263 and covering the installation cavity 261. In this way, by detachably connecting the cover body 267 to the second housing 263, it is convenient to repair and replace components such as the light-emitting member 210 in the installation cavity 261 later, and the operation is convenient.

[0073] Considering that in order to ensure a high lighting effect at the first air outlet 120, in some embodiments, referring to Figures 4 to 6As shown, the light-emitting component 210 may include a circuit board 211 (such as a PCB board) and a light-emitting element 212 (such as a lamp bead) disposed on the circuit board 211. Further, the light-emitting assembly 2 may further include a lamp cup 240 which is arranged to surround the light-emitting element 212 (such as a lamp bead) and is located between the circuit board 211 and the imaging component 220. In this way, through the arrangement of the lamp cup 240, the convergence of the light emitted by the light-emitting element 212 can be achieved, and the effect of light concentration can be obtained, so that the light emitted after being concentrated by the lamp cup 240 irradiates on the outer peripheral wall of the imaging component 220, and after the light irradiates on the illumination area 130 through the imaging component 220, it can be ensured that a relatively clear image effect can be formed at the illumination area 130, and a high lighting effect can be ensured at the first air outlet 120.

[0074] In addition, it can be understood that when the above-mentioned light-emitting elements 212 are arranged in plurality, the lamp cups 240 can also be adaptively arranged in plurality and arranged in one-to-one correspondence with the plurality of light-emitting elements 212. That is, it can be understood that each lamp cup 240 is configured to surround the corresponding light-emitting element 212 (such as a lamp bead) and is located between the circuit board 211 and the imaging component 220. In this way, the image clarity of the image effect formed at the illumination area 130 can be improved, and the lighting effect at the first air outlet 120 can be enhanced.

[0075] In addition, as Figures 4 to 6 shown, the lamp cup 240 may include a cylindrical body 241. The cylindrical body 241 is disposed in the installation cavity 261, one end is connected to the second housing 263, and the other end is connected to the circuit board 211. An outgoing light channel 242 is provided inside the cylindrical body 241, and the inner diameter of the outgoing light channel 242 gradually increases from the light-emitting element 212 towards the imaging component 220. That is, it can be understood that a light inlet hole communicating with the outgoing light channel 242 is formed at one end of the cylindrical body 241 connected to the circuit board 211, and an outgoing light hole 262 as described above communicating with the outgoing light channel 242 and the imaging component 220 is formed at one end of the cylindrical body 241 connected to the second housing 263. In this way, through the arrangement of the cylindrical body 241, the convergence of the light emitted by the light-emitting element 212 can be achieved. While achieving the effect of light concentration, it can also ensure that the light at the outgoing light hole 262 has a large divergence angle, improve the outgoing light uniformity at the light-transmitting part 180, and contribute to enhancing the outgoing light uniformity at the first air outlet 120.

[0076] In addition, in some embodiments, a lens assembly 250 is disposed within the lamp cup 240. The lens assembly 250 is located between the light-emitting element 212 and the imaging member 220. That is, it can be understood that the lens assembly 250 can be disposed within the light-emitting channel 242 of the lamp cup 240. In this way, while the lamp cup 240 can be used to mount and fix the lens assembly 250, a higher 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 formed at the illumination area 130 and enhance the lighting effect at the first air outlet 120.

[0077] Among them, the present disclosure does not specifically limit the specific structure of the above lens assembly 250 and the specific number of lenses arranged. Those skilled in the art can adaptively design according to actual application requirements. In addition, it can be understood that in order to facilitate the lamp cup 240 to converge light, the above lamp cup 240 can be prepared from, for example, light-impermeable materials.

[0078] In addition, the present disclosure does not specifically limit the distance between the light-emitting element 212 and the imaging member 220, the distance between the imaging member 220 and the light-transmitting portion 180, and the distance between the light-transmitting portion 180 and the illumination area 130. Those skilled in the art can adaptively design according to actual application requirements. The purpose is to ensure that the light-emitting member 210 emits light to the illumination area 130 on the inner wall surface 150 of the enclosed air duct 110 of the air duct structure 1, and at least part of the light is reflected through the illumination area 130 and emitted through the first air outlet 120 of the air duct 110, so that a lighting effect formed, for example, at the illumination area 130 can be presented at the first air outlet 120.

[0079] Optionally, in some embodiments, referring to Figure 2 and Figure 3 as shown, the air duct structure 1 may further include a shielding assembly 190 disposed at the first air outlet 120. The shielding assembly 190 includes a plurality of flow guiding plates 191. The plurality of flow guiding plates 191 have an open state for opening the first air outlet 120 and a closed state for closing the first air outlet 120. In the open state, at least part of the light passing through the illumination area 130 can be observed through the gaps between the plurality of flow guiding plates 191 from outside the shielding assembly 190. In this way, when the plurality of flow guiding plates 191 are in the open state, it is convenient to present a lighting effect formed, for example, at the illumination area 130 at the first air outlet 120, which helps to improve the lighting atmosphere at the first air outlet 120. And due to the arrangement of the flow guiding plates 191, when the flow guiding plates 191 are in the open state, the direction of the air flow at the first air outlet 120 can be adjusted by adjusting the opening angle of the flow guiding plates 191, and at the same time, the air flow in the air duct 110 can be discharged more smoothly, which can reduce the noise during the operation of, for example, an air conditioner.

[0080] In addition, it can be understood that when the deflector 191 is adjusted to a closed state, for example, it can also play a role in dust prevention for the air duct 110. Moreover, when the deflector 191 is adjusted to a closed state, for example, the deflector 191 can be made of a light-transmitting material. In this way, even when the deflector 191 is in the closed state, the lighting effect formed in the lighting area 130 can still be presented at the first air outlet 120, improving the lighting effect atmosphere at the first air outlet 120. The present disclosure is not limited thereto.

[0081] Exemplarily, in some embodiments, referring to Figure 2 and Figure 3 as shown, the shielding assembly 190 may include a second driving mechanism 192. The second driving mechanism 192 is drivingly connected to a plurality of deflectors 191 to drive the plurality of deflectors 191 to switch between an open state and a closed state. The second driving mechanism 192 is located between the first air outlet 120 and the light-emitting assembly 2. Exemplarily, the air duct structure 1 includes a first plate body 171. The first plate body 171 includes a first plate portion 1711, a light-transmitting portion 180, and a second plate portion 1712 that are sequentially connected. The extending directions of the first plate portion 1711 and the second plate portion 1712 form an angle. The first air outlet 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 disposed on the outer wall surface of the second plate portion 1712. In this way, the light-emitting assembly 2 is disposed between the first plate body 171 and the second driving mechanism 192, and emits light to the lighting area 130 through the light-transmitting portion 180. That is, the second driving mechanism 192 is located between the first air outlet 120 and the light-emitting assembly 2. Such an arrangement can achieve presenting, at the first air outlet 120, the lighting effect formed in the lighting area 130, for example, while also making the overall structure of the air duct device relatively compact, providing a larger design space for the design of, for example, an air conditioner. And by disposing the light-emitting assembly 2 between the first plate body 171 and the second driving mechanism 192 and emitting light to the lighting area 130 through the light-transmitting portion 180, the path that the light passes through can be shortened, reducing energy loss and ensuring that the light irradiated into the lighting area 130 forms a good lighting effect in the lighting area 130.

[0082] Among them, the present disclosure does not specifically limit the specific connection structure of the second driving mechanism 192 drivingly connected to the plurality of deflectors 191. 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 deflectors 191 according to actual application requirements. For example, the second driving mechanism 192 may include a motor, and the corresponding second transmission connection structure may include a gear transmission structure or a link mechanism transmission structure, etc. The purpose is to be able to achieve the second driving mechanism 192 driving the plurality of deflectors 191 to switch between an open state and a closed state.

[0083] According to a second aspect of the present disclosure, there is provided an indoor unit, which includes the air duct device provided in the first aspect and a first housing 3. The first housing 3 has an inner cavity (not shown) for installing the air duct device and an opening (not shown) for communicating the first air outlet 120 with the outside. This indoor unit can solve the problems in the related art that the external structure design of the air conditioner is relatively complex and the lighting effect is poor, and improve the lighting effect atmosphere and user experience of the air conditioner. In addition, this indoor unit has all the beneficial effects of the air duct device provided in the first aspect, and the present disclosure will not elaborate here.

[0084] In some embodiments, the opening can be provided on the outer side wall of the first housing 3 and adjacent to the bottom end of the first housing 3, so as to facilitate discharging the air flow in the air duct 110 of the air duct structure 1 from the opening at the bottom end of the first housing 3 to the outside of the first housing 3, so as to improve, for example, the energy efficiency of the air conditioner and reduce the accumulation of dust at the opening.

[0085] In addition, it can be understood that the second air outlet 140 can be arranged in communication with, for example, an air outlet passage (not shown) in the first housing 3 of the air conditioner, and an air outlet assembly (such as a fan not shown) can be provided in the first housing 3 to be able to send air into the air outlet passage through the air outlet assembly. And 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, it can be realized that the air flow in the air conditioner, for example, is sent through the air outlet passage and discharged to the outside of the first housing 3 along the extending direction of the air duct 110 of the air duct structure 1 through the opening located at the bottom end of the first housing 3 and in communication with the first air outlet 120 of the air duct 110 of the air duct structure 1, so as to achieve, for example, the air outlet of the air conditioner.

[0086] According to a third aspect of the present disclosure, there is provided an air conditioner, which includes the indoor unit provided in the second aspect. This air conditioner can solve the problems in the related art that the external structure design of the air conditioner is relatively complex and the lighting effect is poor, and improve the lighting effect atmosphere and user experience of the air conditioner, and has all the beneficial effects of the indoor unit provided in the second aspect, and the present disclosure will not elaborate here.
