[0036] The following describes the air conditioner indoor unit 100 according to an embodiment of the present utility model with reference to the accompanying drawings.

[0037] As Figures 1 - 2 shown, the air conditioner indoor unit 100 according to an embodiment of the present utility model includes an air duct assembly. The air duct assembly includes a first air deflector 11 and a second air deflector 12. The first air deflector 11 and the second air deflector 12 are opposite to each other in a first direction. An air outlet passage 10 is defined between the first air deflector 11 and the second air deflector 12. That is to say, the air conditioner indoor unit 100 of the present utility model sends air into the room through the air outlet passage 10.

[0038] The first air deflector 11 is made of heat-insulating material. The first air deflector 11 has a convex portion 111 protruding in a direction away from the second air deflector 12. The convex portion 111 is adapted to be arranged on the installation surface to install the first air deflector 11 through the convex portion 111. That is to say, the convex portion 111 can be adapted to the installation surface so that the first air deflector 11 is stably placed or fixed on the installation surface through the convex portion 111.

[0039] Among them, the installation surface can be the inner wall surface of a furniture cabinet; or, the installation surface can be the inner wall surface of a room; or, the installation surface can be the inner wall surface of the housing of the air conditioner indoor unit 100; or, the installation surface can also be other surfaces capable of installing the first air deflector 11.

[0040] The indoor unit in the related art includes an upper guide plate and a lower air deflector assembly. The lower air deflector plate includes a lower air deflector plate, a support frame, and a heat-insulating layer. An air supply passage is formed between the lower air deflector plate and the upper guide plate. The heat-insulating layer can play a role in heat insulation and heat preservation. The heat-insulating layer is attached to the surface of the lower air deflector plate to avoid the influence on the air flow temperature in the air supply passage. The lower air deflector plate is connected to the support frame, and the support frame can be installed at a preset installation position (such as inside a furniture cabinet) so that the support frame plays a supporting role for the lower air deflector plate. When assembling the air duct, it is necessary to first install the air deflector plate and the support frame, and then attach the heat-insulating layer to the surface of the lower air deflector plate, resulting in a large number of assembly processes for the air duct and causing the problem of low assembly efficiency.

[0041] The first air guiding member 11 of the air conditioner indoor unit 100 according to the embodiment of the present utility model has a convex portion 111 for supporting and installing the first air guiding member 11. The convex portion 111 can be used to support and install the first air guiding member 11. And the first air guiding member 11 is made of heat insulating material as a whole, so that the first air guiding member 11 itself has the function of heat insulation and heat preservation. Compared with the related art, when assembling the air conditioner indoor unit 100 according to the embodiment of the present utility model, there is no need to assemble an additional support structure and a heat insulating layer for heat preservation on the first air guiding member 11. Therefore, the assembly process of the air conditioner indoor unit 100 according to the embodiment of the present utility model is reduced, and the assembly efficiency of the air conditioner indoor unit 100 according to the embodiment of the present utility model is improved.

[0042] In addition, the materials or structures of the lower air guiding plate, the support frame and the heat insulating layer of the lower air guiding assembly in the related art are different. When the environmental temperature changes, the volumes of the lower air guiding plate, the support frame and the heat insulating layer may change to different degrees, causing friction between the lower air guiding plate, the support frame and the heat insulating layer, and thus generating noise, which affects the user experience. The first air guiding member 11 of the air conditioner indoor unit 100 according to the embodiment of the present utility model is integrated with the convex portion 111 that supports it, and no noise will be generated when the environmental temperature changes, providing a better user experience.

[0043] To make the present application easier to understand, the following takes the first direction being consistent with the up and down direction and the width direction of the air outlet passage 10 being consistent with the front and back direction (not shown in the figure) as an example to further describe the air conditioner indoor unit 100 according to the embodiment of the present utility model. Among them, the front and back direction is perpendicular to the up and down direction and the left and right direction.

[0044] As Figures 1 - 2 shown, the air conditioner indoor unit 100 of the present embodiment further includes a housing, a blower 4 and a heat exchanger 5.

[0045] The housing includes an enclosure 2 and a first air guiding member 11. The enclosure 2 is connected to the first air guiding member 11, and an installation cavity 3 is defined between the enclosure 2 and the first air guiding member 11. A second air guiding member 12 is connected to the enclosure 2, and the second air guiding member 12 is located in the installation cavity 3.

[0046] The housing further includes an air inlet 21 and an air outlet 22. The heat exchanger 5 and the blower 4 are both arranged in the installation cavity 3. The blower 4 is used to promote the formation of an air flow that enters the air conditioner indoor unit 100 from the air inlet 21 and blows out from the air outlet 22. The heat exchanger 5 is located between the air inlet 21 and the blower 4, and the heat exchanger 5 is used to exchange heat with the air flow that enters the air conditioner indoor unit 100 from the air inlet 21.

[0047] The housing is formed by using the shroud 2 and the first air guiding member 11, making the structure of the housing simpler and reducing the redundancy of the housing structure. Moreover, when installing the housing, the protrusion 111 of the first air guiding member 11 can be used to support the entire air conditioner indoor unit 100 of this embodiment, so that there is no need to additionally assemble a support structure on the housing, reducing the assembly process of the air conditioner indoor unit 100 of this embodiment, and thus further improving the assembly efficiency.

[0048] Specifically, the lower part of the shroud 2 is open, and the first air guiding member 11 is connected to the lower part of the shroud 2, so that the first air guiding member 11 and the shroud 2 form an installation cavity 3. The air outlet end of the air outlet passage 10 is defined between the left end of the second air guiding member 12 and the left end of the first air guiding member 11. An air outlet 22 is formed on the left side wall surface of the shroud 2, and the left end of the second air guiding member 12 is connected to the air outlet 22, so that the air outlet end corresponds to the air outlet 22, and the air flow in the air outlet passage 10 is blown to the indoor area outside through the air outlet end.

[0049] In some embodiments, as Figure 6 shown, the air conditioner indoor unit 100 is an embedded air conditioner indoor unit 100, configured to be embedded and installed in an installation groove 201 for accommodating the air conditioner indoor unit 100. For example, the installation groove 201 is formed in a cabinet 200. The installation groove 201 has an open opening that is open to the right, so that the air conditioner indoor unit 100 enters the installation groove 201 through the open opening, facilitating the installation of the air conditioner indoor unit 100.

[0050] The protrusion 111 is provided on the bottom wall surface 202 of the installation groove 201, so that the protrusion 111 supports the air conditioner indoor unit 100, and the bottom wall surface 202 forms an installation surface.

[0051] The air conditioner indoor unit 100 is embedded in the installation groove 201 of a furniture cabinet or a wall, so as to hide the air conditioner indoor unit 100 in appearance, making the home layout more beautiful and achieving the purpose of improving the user experience.

[0052] Both the air inlet 21 and the air outlet 22 correspond to the open opening, that is, the air inlet 21 and the air outlet 22 are opened on the left side of the housing, so as to avoid the wall surface of the installation groove 201 blocking the air inlet 21 and the air outlet 22, facilitating the air intake and air outlet of the air conditioner indoor unit 100.

[0053] In some embodiments, as Figure 1 and Figure 2As shown, the first air guiding member 11 includes a first section 112 and a second section 113, and the first section 112 and the second section 113 are arranged in sequence in the extending direction of the air outlet channel 10. An air inlet end of the air outlet channel 10 is formed between one end of the first section 112 and one end of the second air guiding member 12. The other end of the first section 112 is connected to one end of the second section 113, and an air outlet end of the air outlet channel 10 is formed between the other end of the second section 113 and the other end of the second air guiding member 12.

[0054] The first section 112 forms an arc-shaped bend. The first section 112 is adapted to the outer contour of the blower 4, so that the wall surface of the first section 112 produces less resistance to the air flow, so that the air flow blown out by the blower 4 can enter the air outlet channel 10 more smoothly, avoiding the reduction of the air flow velocity and ensuring the air supply quality of the air conditioner indoor unit 100.

[0055] The second section 113 has a convex portion 111. That is to say, a part of the second section 113 plays a supporting role for the first air guiding member 11.

[0056] Preferably, the cross-sectional area of the second section 113 increases in the left-to-right direction. A part of the second section 113 forms a convex portion 111, that is, the outer contour of the cross-section of the second section 113 is triangular, making the structure of the second section 113 more stable, so as to provide a more stable support for the first air guiding member 11 and other components connected thereto.

[0057] Optionally, the material of the first air guiding member 11 can be polyurethane foam; or, the material of the first air guiding member 11 can be polystyrene foam; or, the material of the first air guiding member 11 can also be other heat insulating materials.

[0058] In some embodiments, as Figures 3 - 5 shown, the air duct assembly further includes a noise reduction structure, and a plurality of noise reduction structures are arranged in the air outlet channel 10. Thus, by arranging a plurality of noise reduction structures in the air outlet channel 10, the noise generated during air outlet is reduced, thereby improving the user experience of the customer.

[0059] In some embodiments, a plurality of noise reduction holes (not shown in the figure) are provided on the inner wall surface of the first air guiding member 11, and the noise reduction holes form a noise reduction structure. By arranging a plurality of noise reduction holes in the air outlet channel 10, when there is noise in the air outlet channel 10, for example, the sound generated when the blower 4 in the installation cavity 3 is running, the noise will spread to the noise reduction holes when passing through the air outlet channel 10 and collide repeatedly in the noise reduction holes, so that part or all of the energy of the noise sound wave is consumed in the noise reduction holes, achieving the purpose of noise reduction.

[0060] In some other embodiments, the air duct assembly further includes a plurality of protruding members 13, and the plurality of protruding members 13 are provided on the inner wall surface of the first air guiding member 11. Each protruding member 13 extends along the extending direction of the air outlet passage 10, and each protruding member 13 protrudes towards the second air guiding member 12. The plurality of protruding members 13 are arranged side by side in the front-rear direction, and a sound absorption groove 131 is defined between adjacent protruding members 13. The width direction of the air outlet passage 10 is perpendicular to the extending direction of the air outlet passage 10.

[0061] When there is noise in the air outlet passage 10, the noise will spread into the sound absorption groove 131 when passing through the air outlet passage 10 and collide repeatedly in the sound absorption groove 131, so that part or all of the energy of the noise sound wave is consumed in the sound absorption groove 131, achieving the purpose of noise reduction.

[0062] Furthermore, the cross-sectional area of each protruding member 13 increases in the direction from the first air guiding member 11 to the second air guiding member 12, enabling the sound absorption groove 131 to have a better attenuation effect on the noise sound wave, thereby further improving the noise reduction effect of the sound absorption groove 131.

[0063] Preferably, the plurality of protruding members 13 and the first air guiding member 11 are integrally formed, integrating the plurality of protruding members 13 and the first air guiding member 11, thereby facilitating the assembly of the air conditioner indoor unit 100 of the embodiment of the present invention.

[0064] The air conditioner of the embodiment of the present invention includes the air conditioner indoor unit 100 of any of the above embodiments. The first air guiding member 11 of the air conditioner indoor unit 100 of the embodiment of the present invention has a protruding portion 111 for supporting and installing the first air guiding member 11, and the protruding portion 111 can be used to support and install the first air guiding member 11. And the first air guiding member 11 is made of a heat-insulating material as a whole, enabling the first air guiding member 11 to have the function of heat insulation and heat preservation by itself.

[0065] When assembling the air conditioner indoor unit 100 of the embodiment of the present invention, there is no need to assemble an additional support structure and a heat-insulating layer for heat preservation on the first air guiding member 11. Therefore, the assembly process of the air conditioner indoor unit 100 of the embodiment of the present invention is reduced, and the assembly efficiency of the air conditioner indoor unit 100 of the embodiment of the present invention is improved.

[0066] So far, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, still, without departing from the spirit and scope of the present invention, many other variations or modifications that conform to the principles of the present invention can be directly determined or deduced based on the content disclosed in the present invention.
