[0034] The utility model provides an indoor unit of an air conditioner.

[0035] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the air conditioner indoor unit comprises:

[0036] Housing 100;

[0037] An integrally formed volute 200 is disposed in the housing 100 to construct an air duct, and an air guide wall is formed on opposite sides of the volute 200. The two air guide walls are respectively a first wall 211 for constructing a first air duct 221 and a second wall 212 for constructing a second air duct 222. The first wall 211 and the second wall 212 are asymmetrically arranged with respect to the central axis of the housing 100; and

[0038] The two wind guide wheels are a first wind wheel 310 installed corresponding to the inlet of the first wind duct 221 and a second wind wheel 320 installed corresponding to the inlet of the second wind duct 222 .

[0039] In the technical solution of the utility model, the air conditioner indoor unit is provided with two air ducts and two wind wheels, and the two wind wheels and the two air ducts are arranged one by one, which is conducive to increasing the air volume of the air conditioner indoor unit, thereby improving the heat exchange capacity of the air conditioner. On this basis, the first wall 211 and the second wall 212 are arranged asymmetrically, so that the entrance of the first air duct 221 and the entrance of the second air duct 222 can be staggered, and the first wind wheel 310 and the second wind wheel 320 can be staggered in the casing 100, which can make full use of the space in the casing 100, which is conducive to the miniaturization design of the air conditioner indoor unit, that is, the air conditioner can use a smaller space to generate a larger air volume. In addition, the volute 200 is processed and formed by an integrated molding process, which can avoid the generation of seams in the air duct and ensure the continuity of a single air duct. At the same time, the consistency of the first wall 211 and the second wall 212 can be high, which is conducive to ensuring the consistency of the wind guide of the two air ducts. In addition, the process of assembling the volute 200 can be omitted, which is conducive to improving the assembly efficiency of the air conditioner indoor unit.

[0040] Specifically, the volute 200 is integrally formed by an injection molding process or an extrusion molding process. It can be understood that the injection molding process is to feed the raw materials into the injection molding machine to heat and soften them, and then inject them into the mold by rotating and pressurizing the screw rod, wait until the material completely fills the mold, gradually cools and forms, and then use a ejector pin to push the product out of the mold; extrusion molding is extrusion molding, and the raw materials also need to be fed into the machine to heat and soften them, and then the material is squeezed by a screw rod or a plunger, and it is shaped through the head mold. After the product passes through the mold, it will continue to extend, and after cooling, it will be shaped, and finally the product will be cut according to the required length to obtain the final product. The volute 200 is formed by an injection molding process or an extrusion molding process, which can ensure the molding quality and production efficiency of the volute 200.

[0041] Furthermore, in the present embodiment, the first wall surface 211 is arranged closer to the rear of the housing 100 relative to the second wall surface 212. It can be understood that the rear end of the wind guide wall surface is also the entrance of the air duct, the entrance of the first air duct 221 is also further back than the entrance of the second air duct 222, and the first wind wheel 310 is also correspondingly further back than the second wind wheel 320. In this way, the first wind wheel 310 and the second wind wheel 320 can be staggered in the housing 100, which can make full use of the space in the housing 100, which is conducive to the miniaturization design of the air conditioner indoor unit, that is, the air conditioner can use a smaller space to generate a larger air volume. Of course, in other embodiments, the first wall surface and the second wall surface can also be staggered and extended in other directions.

[0042] Furthermore, in this embodiment, the volute 200 also includes a partition 230, which is connected to the rear end of the second wall 212 and extends backward. In this way, two spaces can be separated by the partition 230, and two wind guide wheels respectively operate in the spaces on both sides of the partition 230, and can respectively send the airflow on both sides of the outside of the casing 100 into the two air ducts, so that the air intake of the two air ducts can be more orderly, ensuring the air intake of the air conditioner indoor unit, and helping to reduce airflow noise. Of course, in other embodiments, the partition can also be achieved by other structures outside the volute 200, such as the casing 100.

[0043] Furthermore, in this embodiment, the partition portion 230 is arranged corresponding to the central axis extending in the front-to-back direction of the cross section of the housing 100. That is, the extending direction of the partition portion 230 coincides or approximately coincides with the above-mentioned central axis of the housing 100. In this way, the space sizes on both sides of the partition portion 230 are substantially equal, which can ensure that the air inlet areas of the two air ducts are equal, which is conducive to ensuring that the air volumes of the two air ducts are equal.

[0044] Furthermore, in this embodiment, the air conditioner indoor unit further includes a heat exchanger 400, which is U-shaped and arranged relative to the two wind guide wheels. It can be understood that the U-shaped heat exchanger 400 can provide a sufficiently large heat exchange area, and can match the contour shape of the housing 100, occupying a small space, and the remaining space in the housing 100 is large enough to facilitate the accommodation of the wind guide wheel, and to give up a large enough space for the air duct, while ensuring the miniaturization of the air conditioner indoor unit, ensuring the air volume of the air conditioner indoor unit. Among them, the symmetry axis of the heat exchanger 400 is arranged corresponding to the above-mentioned central axis of the housing 100, so that the partition part 230 is arranged corresponding to the symmetry axis of the heat exchanger 400, so that the heat exchanger 400 can provide a considerable heat exchange area for the airflow on both sides of the partition part 230, which is conducive to ensuring the consistency of the air outlet of the two air ducts. Of course, in other embodiments, the heat exchanger 400 can be other shapes, such as arc shape or M shape.

[0045] Furthermore, in this embodiment, the volute 200 further includes a connecting portion 240, and the rear end of the first wall 211 is connected to the partition portion 230 through the connecting portion 240. In this way, the back space of the first wall 211 can be closed, and when a gap is formed between the partition portion 230 and the rear section of the first wall 211, the airflow will not flow into the gap under the blocking of the connecting portion 240, which is conducive to reducing the airflow noise and ensuring the air intake of the first air duct 221. Of course, in other embodiments, the rear end of the first wall 211 may also abut against the heat exchanger 400 to form a blockage of the gap.

[0046] Furthermore, in this embodiment, the wind guide wall includes a first wind guide section 213 and a second wind guide section 214 distributed in the extension direction of the air duct, and the wind guide wheel is arranged corresponding to the first wind guide section 213, and the two first wind guide sections 213 are convexly arranged facing each other, and the two second wind guide sections 214 are convexly arranged facing each other. In this way, the orientation of the first wind duct 221 and the second wind duct 222 at the entrance will be relatively dispersed, which is conducive to inhaling more indoor air to ensure the air intake of the air conditioner indoor unit, and the orientation at the outlet will be relatively concentrated, which is conducive to the compact design of the two wind ducts. At the same time, it also enables the air conditioner indoor unit to centrally supply air, especially, it can make the air conditioner indoor unit centrally discharge air forward, which is conducive to improving the wind feeling felt by the user when the air conditioner indoor unit is configured as a cabinet unit. Of course, in other embodiments, the first wind duct 221 and the second wind duct 222 can also extend in other extension directions.

[0047] The air conditioner indoor unit can be configured as a wall-mounted cabinet or a vertical cabinet. In particular, when the air conditioner indoor unit is configured as a wall-mounted indoor unit, the air conditioner indoor unit can discharge air toward the main torso of the person, which is more conducive to improving the wind feeling felt by the user.

[0048] Further, in this embodiment, the two first air guide sections 213 intersect, and the front end of the first air guide section 213 of the second wall surface 212 is opposite to the second air guide section 214 of the first wall surface 211. It can be understood that the two second air guide sections 214 are convexly arranged in opposite directions, so that a gap is inevitably formed at the second air guide section 214 between the first wall surface 211 and the second wall surface 212, and the front side of the first air guide section 213 of the second wall surface 212 can at least partially be opposite to the second air guide section 214 of the first wall surface 211, so that the front side of the first air guide section 213 can be convexly arranged toward the gap, so that the space at the gap can be utilized, so that the two air ducts are arranged more compactly, which is conducive to realizing the miniaturized design of the air conditioner indoor unit.

[0049] Further, in this embodiment, two air inlet areas 101 are formed on opposite sides of the housing 100 corresponding to the first air duct 221 and the second air duct 222. In this way, the first air duct 221 and the second air duct 222 have their own air inlet areas 101. Specifically, each of the air guide wheels and the corresponding air inlet area 101 are respectively located on opposite sides of the heat exchanger 400. Under the action of the air guide wheels, the air on both sides of the housing 100 can enter the corresponding air duct through the air inlet area 101 on the corresponding side. Of course, in other embodiments, the housing 100 can also form an air inlet area 101 that can cover the entrances of the two air ducts.

[0050] Furthermore, in this embodiment, the housing 100 includes a back plate 110, and the two air inlet areas 101 are respectively located on opposite sides of the back plate 110, and the back plate 110 is provided with a hanging part. In this way, the indoor air conditioner can be hung on a wall or a cabinet through the hanging part, wherein the hanging part can be a hook, or can form a recessed space for the hook to hang. Of course, the indoor air conditioner can also be installed on the ground.

[0051] Optionally, the air conditioner indoor unit further includes an electric heater 600, and the electric heater 600 is disposed behind the second wind wheel 320. In this way, in the heating mode of the air conditioner, the electric heater 600 can assist in heating the air to improve the heating capacity of the air conditioner.

[0052] In one embodiment, if Figure 1 As shown, an air outlet 102 is formed on the front side of the housing 100, and the outlets of the two air ducts intersect at the air outlet 102. In this way, the air flowing out of the outlets of the two air ducts can be mixed at the air outlet 102 to ensure the consistency of the air outlet of the air conditioner. In particular, when the electric heater 600 is only arranged behind the second wind wheel 320, the air temperature at the outlet of the second air duct 222 will be higher, and after mixing with the air flowing out of the first air duct 221 at the air outlet 102, the temperature will be more uniform, and the user's body feeling will be better.

[0053] In one embodiment, if Figure 2 As shown, an air outlet 102 is formed at the front side of the housing 100 corresponding to the outlets of the two air ducts. In this way, air can be supplied in a wider range through the two air outlets 102, and the provision of the two air outlets 102 ensures the air volume of the indoor unit of the air conditioner, which is conducive to improving the user experience.

[0054] Further, in the above embodiment, the air outlet 102 is provided with an air guide, and the air guide includes a vertical air guide plate 520 and / or a transverse air guide plate 510. That is, the air outlet 102 is provided with at least one of the vertical air guide plate 520 and the transverse air guide plate 510. It can be understood that the vertical air guide plate 520 extends vertically, swings horizontally, and can swing the wind horizontally, and the transverse air guide plate 510 extends horizontally, swings vertically, and can swing the wind vertically. Under the action of the air guide, the air supply area of ​​the indoor unit of the air conditioner can be increased to achieve a large range of air supply, and when the outlets of the two air ducts intersect at an air outlet 102, the swing of the air guide can accelerate the mixing of the air to ensure the temperature uniformity of the air flowing out of the air outlet 102.

[0055] The utility model also proposes an air conditioner, which includes an air-conditioning indoor unit. The specific structure of the air-conditioning indoor unit refers to the above-mentioned embodiment. Since the air conditioner adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0056] The above description is only an optional embodiment of the present invention, and does not limit the protection scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly used in other related technical fields are included in the protection scope of the present invention.
