[0002] Traditional wall-mounted air conditioner indoor units have a narrow airflow range, only able to deliver air to the front, leaving the left and right sides as blind spots, resulting in poor comfort. To address this, some existing technologies design wall-mounted air conditioner indoor units with a side-discharge structure, allowing them to deliver air both forward and sideways, thus increasing the airflow range. However, current wall-mounted air conditioner indoor units suffer from high noise levels when delivering air laterally, leading to a poor user experience. Utility Model Content

[0003] This application provides a wall-mounted air conditioner indoor unit and an air conditioner to solve the problem of loud airflow noise in existing wall-mounted air conditioner indoor units when discharging air laterally.

[0004] In a first aspect, embodiments of this application provide a wall-mounted air conditioner indoor unit, the wall-mounted air conditioner indoor unit including a casing and a fan, the front side of the casing is provided with a first air outlet, at least one end face of the casing along its length is provided with a mounting groove, the bottom of the mounting groove is provided with a second air outlet communicating with the interior of the casing; the groove wall of the mounting groove near its opening protrudes arc-shaped toward the inside of the mounting groove, the fan is disposed in the mounting groove, and an air outlet channel is formed between the outer periphery of the fan and the groove wall of the mounting groove, the fan is used to drive the airflow inside the casing to flow from the second air outlet to the air outlet channel.

[0005] Optionally, the wall of the mounting groove includes a connecting portion and an arc-shaped portion connected sequentially along the depth direction of the mounting groove. The arc-shaped portion is closer to the opening of the mounting groove than the connecting portion, and the inner surface of the arc-shaped portion protrudes arc-shaped toward the inner side of the mounting groove.

[0006] Optionally, the inner surface of one end of the arcuate portion near the edge of the mounting groove is inclined toward the outside of the mounting groove to form a guide slope.

[0007] Optionally, a guide section is provided inside the housing near the second air outlet, and the guide section has a guide surface for guiding the airflow inside the housing to the second air outlet.

[0008] Optionally, the guide surface is an arc surface or a straight surface.

[0009] Optionally, the fan includes a housing and a fan wheel. The air outlet channel is formed between the outer periphery of the housing and the wall of the mounting groove. The housing is provided with an air inlet and a third air outlet. The air inlet is connected to the second air outlet, and the third air outlet is connected to the air outlet channel. The fan wheel is disposed inside the housing. The air inlet side of the fan wheel is connected to the air inlet, and the air outlet side of the fan wheel is connected to the third air outlet.

[0010] Optionally, the housing has a bottom wall and a side wall, which are respectively disposed opposite to the bottom and side wall of the mounting groove.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] In this application, the term "exemplary" is used to mean "serving as an example, illustration, or illustration." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The term "and / or" includes any and all combinations of one or more of the associated listed items.

[0034] This application provides a wall-mounted air conditioner indoor unit, such as... Figures 1 to 13As shown, the wall-mounted air conditioner indoor unit includes a housing 100 and a fan 200. The front side of the housing 100 is provided with a first air outlet 101. At least one end face of the housing 100 in the length direction is provided with a mounting groove 102. The bottom of the mounting groove 102 is provided with a second air outlet 103 that communicates with the inside of the housing 100. The groove wall 104 of the mounting groove 102 near its opening protrudes arc-shaped toward the inside of the mounting groove 102. The fan 200 is disposed in the mounting groove 102. An air outlet channel 105 is formed between the outer periphery of the fan 200 and the groove wall 104 of the mounting groove 102. The fan 200 is used to drive the airflow inside the housing 100 from the second air outlet 103 to the air outlet channel 105.

[0035] The wall-mounted air conditioner indoor unit provided in this application embodiment has an installation groove 102 provided on at least one end face of the casing 100 along its length. The bottom of the installation groove 102 has a second air outlet 103 communicating with the inside of the casing 100. The groove wall 104 of the installation groove 102 near its opening protrudes arc-shaped toward the inside of the installation groove 102. An air outlet channel 105 is formed between the fan 200 and the groove wall 104 of the installation groove 102, thereby driving the air outlet inside the casing 100 through the fan 200. The airflow flows from the second air outlet 103 to the air outlet channel 105 and is blown out, achieving lateral air supply. As the airflow is blown out of the air outlet channel 105, the groove wall 104 of the mounting groove 102 near its opening protrudes inward in an arc shape. Under the influence of the arc-shaped inward protrusion of the groove wall 104, the airflow will generate the Coanda effect, changing from the initial turbulent flow (the turbulent airflow will hit the inner wall of the air outlet channel 105 and form a whistling sound) to a stable laminar flow. This can effectively reduce the noise of the airflow and improve the user experience.

[0036] The Coanda Effect, also known as the wall adhesion effect, refers to the tendency of a fluid (water or air) to deviate from its original flow direction and flow along the surface of a convex object. When there is surface friction between the fluid and the surface of the object it flows over (which can also be described as fluid viscosity), as long as the curvature is not large, the fluid will flow along the surface of the object.

[0037] Optionally, the mounting groove 102 and the second air outlet 103 may be provided only on one end face along the length of the housing 100, or the mounting groove 102 and the second air outlet 103 may be provided on both ends face along the length of the housing 100. Taking the length of the housing 100 as the left-right direction as an example, the mounting groove 102 and the second air outlet 103 may be provided only on the left end face of the housing 100, or the mounting groove 102 and the second air outlet 103 may be provided only on the right end face of the housing 100; for example... Figures 1-10As shown, mounting grooves 102 and second air outlets 103 can also be provided on both the left and right end faces of the housing 100, and fans 200 are provided on the mounting grooves 102 at both ends of the housing 100.

[0038] By providing a second air outlet 103 and a mounting groove 102 on both ends of the casing 100 along its length, the wall-mounted air conditioner indoor unit can supply air to both the left and right sides, further expanding the air supply range, effectively enhancing indoor air flow, and accelerating indoor air circulation. It is especially suitable for large spaces or long rooms, reducing temperature differences in corners, and creating a surround air atmosphere or gentle breeze, making the user feel more comfortable.

[0039] It is understandable that by setting up a wall-mounted air conditioner indoor unit, air can be supplied from both the left and right sides, so there is no need to set left and right sweeping blades at the first air outlet 101. That is, the left and right sweeping blades set at the front air outlet of the traditional wall-mounted air conditioner indoor unit are eliminated. The negative pressure formed by the fans 200 on both sides guides the airflow inside the casing 100 to the left and right sides, thereby achieving the left and right sweeping effect while reducing the air volume loss at the first air outlet 101.

[0040] In some embodiments of this application, such as Figure 7 and Figure 10 As shown, the groove wall 104 of the mounting groove 102 includes a connecting portion 1041 and an arc-shaped portion 1042 connected sequentially along the depth direction of the mounting groove 102. The arc-shaped portion 1042 is closer to the opening of the mounting groove 102 than the connecting portion 1041, and the inner surface of the arc-shaped portion 1042 protrudes arc-shaped towards the inner side of the mounting groove 102. Specifically, the connecting portion 1041 connects the arc-shaped portion 1042 and the bottom of the mounting groove 102. By setting the inner surface of the arc-shaped portion 1042 to protrude arc-shaped towards the inner side of the mounting groove 102, the airflow from the outlet channel 105 will generate a Coanda effect under the influence of the inner surface of the arc-shaped portion 1042, changing the initial turbulent flow into a stable laminar flow, thereby effectively reducing outlet noise and improving the user experience.

[0041] Optionally, the inner surface of the end of the arc-shaped portion 1042 near the edge of the groove 102 is inclined towards the outside of the groove 102 to form a guide slope 1043. This arrangement allows the airflow from the outlet duct 105 to diffuse along the guide slope 1043, expanding the air supply coverage area and making the airflow gentler, thus improving user comfort.

[0042] In some embodiments of this application, a guide section 110 is provided inside the housing 100 near the second air outlet 103. The guide section 110 has a guide surface 111 for guiding the airflow inside the housing 100 to the second air outlet 103. This arrangement allows the airflow inside the housing 100 to flow to the second air outlet 103 more quickly and effectively after being guided by the guide surface 111, thereby improving the lateral air supply efficiency.

[0043] Optionally, the airflow guide surface 111 can be curved or straight, as long as it can guide the airflow inside the housing 100 to the second air outlet 103. The specific settings can be made according to actual needs.

[0044] In some embodiments of this application, such as Figure 7 , Figure 10 , Figures 12-13 As shown, the fan 200 includes a housing 210 and a rotor 220. An air outlet channel 105 is formed between the outer periphery of the housing 210 and the groove wall 104 of the mounting groove 102. The housing 210 is provided with an air inlet 201 and a third air outlet 202. The air inlet 201 communicates with the second air outlet 103, and the third air outlet 202 communicates with the air outlet channel 105. The rotor 220 is disposed inside the housing 210. The air inlet side of the rotor 220 communicates with the air inlet 201, and the air outlet side of the rotor 220 communicates with the third air outlet 202. For details, please refer to [reference needed]. Figure 7 and Figure 10 The thick solid arrows in the figure indicate the direction of airflow. When the impeller 220 is working, the airflow in the drive housing 100 flows through the second air outlet 103, the air inlet 201 and the third air outlet 202 in sequence into the air outlet channel 105, and finally blows out from the air outlet channel 105 to achieve lateral air supply.

[0045] Optionally, the housing 210 has a bottom wall 211 and a side wall 212, which are respectively positioned opposite to the bottom and wall 104 of the mounting groove 102. An air inlet 201 is located on the bottom wall 211, and a third air outlet 202 is located on the side wall 212. The axis of the impeller 220 is positioned along the length of the housing 100. This configuration allows the impeller 220 to occupy a smaller area in the depth direction of the mounting groove 102, and also enables the airflow to flow effectively into the air outlet channel 105. Guided by the arc-shaped, convex groove wall 104, the airflow generates a Coanda effect, transforming the initial turbulent flow into a stable laminar flow, thereby reducing airflow noise and improving the user experience.

[0046] Optionally, the fan 200 includes multiple impellers 220, which are spaced apart along the length of the mounting groove 102. By setting multiple impellers 220, their synergistic effect can significantly improve the air volume and efficiency; arranging the multiple impellers 220 spaced apart along the length of the mounting groove 102 allows for uniform distribution of the airflow within the outlet channel 105, thereby achieving uniform airflow. For example, as... Figure 10 As shown, the fan 200 includes two impellers 220, which are arranged at intervals along the length of the mounting groove 102.

[0047] Optionally, the impeller 220 can be either a cross-flow impeller 220 or a centrifugal impeller 220, depending on the actual needs.

[0048] In some embodiments of this application, such as Figures 1-10 As shown, the wall-mounted air conditioner indoor unit also includes a decorative panel 300. The decorative panel 300 is disposed at the opening of the mounting groove 102 to cover the fan 200. An annular air outlet 107 is formed between the periphery of the decorative panel 300 and the periphery of the opening of the mounting groove 102, and the annular air outlet 107 is connected to the air outlet duct 105. With this arrangement, the decorative panel 300 can cover the fan 200 without affecting the lateral air supply, so that the user cannot directly see the fan 200 from the outside, thereby improving the overall aesthetics of the unit.

[0049] For details, please refer to Figure 7 and Figure 10 The thick solid arrows in the figure indicate the direction of airflow. When the impeller 220 is working, the airflow in the drive housing 100 flows through the second air outlet 103, the air inlet 201 and the third air outlet 202 in sequence into the air outlet channel 105, and finally blows out from the air outlet channel 105 through the annular air outlet 107 to achieve lateral air supply.

[0050] Optionally, the wall-mounted air conditioner indoor unit also includes an air guide plate 400, which is disposed at the first air outlet 101. The air guide plate 400 extends along the length of the casing 100 and can rotate around the length of the casing 100 to open or close the air outlet. When the air guide plate 400 opens the first air outlet 101, the wall-mounted air conditioner indoor unit can achieve front airflow.

[0051] This application also provides an air conditioner, which includes a wall-mounted indoor unit. The specific structure of the wall-mounted indoor unit is as described in the above embodiments. Since this air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.
