[0002] With economic development and improved living standards, people's expectations for air conditioners go beyond just faster and better cooling and heating speeds; they are increasingly concerned about the airflow experience. In related technologies, wall-mounted air conditioners have a single airflow pattern and a short airflow distance, leading to inconsistent temperatures within the room and reducing the user experience. Utility Model Content
[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0006] According to the embodiments of the present invention, the air conditioner's exhaust vent is connected to both the front and side air outlets. When the air conditioner is operating, the heat-exchange airflow blown by the centrifugal fan can be simultaneously discharged through both the front and side air outlets. This increases the air outlet area of the air conditioner and allows the heat-exchange airflow to be evenly distributed throughout the room. Furthermore, because the air conditioner of this invention uses a centrifugal fan to drive the heat-exchange airflow, compared to a cross-flow fan, it can extend the distance the heat-exchange airflow travels from the front and side air outlets. Therefore, the air conditioner of this embodiment can meet long-distance air delivery needs and has a better airflow effect, which is beneficial for improving the uniformity of room temperature.

The first partition is located behind the front air outlet and the side air outlet and is orthogonal to the front-rear direction of the housing. The second partition is located below the front air outlet and the side air outlet and is orthogonal to the vertical direction of the housing.
[0010] In some embodiments, the centrifugal fan includes a volute, the volute including a connected volute body and a diffuser section, the volute body being located behind the first partition, and the front end of the diffuser section passing through the first partition and extending into the air guide cavity.
[0011] In some embodiments, the heat exchanger is located below the centrifugal fan and the air guide cavity, and the heat exchanger is arranged opposite to the air inlet.
[0012] In some embodiments, the heat exchanger is a straight plate heat exchanger or an arc-shaped heat exchanger, the heat exchanger gradually extends downward in a front-to-back direction, and the air conditioner also includes a water receiving tray, the water receiving tray is located inside the housing and is disposed at the lower edge of the rear end of the heat exchanger.
[0013] In some embodiments, the angle between the heat exchanger wall and the front-rear direction of the shell is α, where 20°≤α≤50°.

[0030] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0031] The following is a reference appendix. Figures 1 to 6 An air conditioner according to an embodiment of the present invention.
[0032] like Figures 1 to 6 As shown, the air conditioner of this utility model embodiment includes: a housing 1, a heat exchanger 2, and a centrifugal fan 3. The housing 1 has an air inlet 11 on its lower side, a front air outlet 12 on its front side, and a side air outlet 13 on at least one side of the housing 1 along its left-right direction. The heat exchanger 2 is disposed inside the housing 1, and the centrifugal fan 3 is disposed inside the housing 1. The centrifugal fan 3 has an exhaust port 3121, which communicates with the front air outlet 12 and the side air outlet 13.
[0033] According to the embodiment of the present invention, since the exhaust vent 3121 is connected to the front air outlet 12 and the side air outlet 13, when the air conditioner is working, the heat exchange airflow blown by the centrifugal fan 3 can be discharged simultaneously through the front air outlet 12 and the side air outlet 13. This increases the air outlet area of the air conditioner and allows the heat exchange airflow to be evenly diffused to various locations in the room. On the other hand, since the air conditioner of the present invention uses a centrifugal fan 3 to drive the heat exchange airflow, compared with a cross-flow fan, the distance that the heat exchange airflow is blown out from the front air outlet 12 and the side air outlet 13 can be extended.
[0034] Therefore, the air conditioner of this utility model can meet the needs of long-distance air supply and has a better air output effect, which is conducive to improving the uniformity of room temperature.
[0035] It should be noted that the up, down, front, back, left, and right directions of the casing 1 are consistent with the up, down, front, back, left, and right directions of the air conditioner after installation.
[0036] For example, a side air outlet 13 may be provided only on the left side of the housing 1. Or, a side air outlet 13 may be provided only on the right side of the housing 1. Yet another example is that side air outlets 13 may be provided on both the left and right sides of the housing 1.
[0037] like Figure 2 and Figure 3 As shown in the example of this utility model, there are two side air outlets 13, which are located on the left and right sides of the housing 1, respectively. This allows the air conditioner to supply air from three sides, which can significantly increase the air supply area of the air conditioner and regulate the indoor temperature more quickly.
[0038] The two side air outlets 13 are at the same horizontal level as the front air outlet 12, which makes the air volume and air temperature of the air conditioner more uniform.
[0039] In some embodiments, such as Figures 4 to 6 As shown, the exhaust vent 3121 and the front air outlet 12 are arranged opposite each other and spaced apart in the front-rear direction of the housing 1. Thus, most of the heat exchange airflow discharged from the exhaust vent 3121 can be discharged through the front air outlet 12, while a small portion of the heat exchange airflow is discharged through the side air outlet 13. This ensures both effective front airflow from the air conditioner and gentle airflow from the left and right sides, thus solving the problem of rapid downward sinking of cold air in cooling mode. It allows the airflow to evenly cover the entire room, ensuring uniform temperature throughout the room and resolving the issue of poor user experience caused by direct airflow.
[0040] Optionally, such as Figure 4 and Figure 5 As shown, the air conditioner also includes a partition assembly 4, which is disposed within the housing 1 and forms an air guide cavity 43 with the inner wall of the housing 1. The exhaust port 3121, the front air outlet 12, and the side air outlet 13 are all connected to the air guide cavity 43. It can be understood that the centrifugal fan 3 can guide the heat-exchanged airflow into the air guide cavity 43, and then distribute it to the front air outlet 12 and the side air outlet 13, thereby reducing the turbulence on the heat-exchanged airflow during the operation of the centrifugal fan 3. In other words, the partition assembly 4 can separate the air intake and exhaust ends of the centrifugal fan 3, thus preventing airflow disturbance during the operation of the centrifugal fan 3. This helps to improve the air outlet efficiency of the air conditioner and reduce energy consumption.
[0041] Specifically, such as Figures 4 to 6 As shown, the partition assembly 4 includes a first partition 41 and a second partition 42. The first partition 41, the second partition 42 and the inner wall of the housing 1 form an air guide cavity 43. The first partition 41 is located behind the front air outlet 12 and the side air outlet 13. The first partition 41 is orthogonal to the front-rear direction of the housing 1. The second partition 42 is located below the front air outlet 12 and the side air outlet 13. The second partition 42 is orthogonal to the vertical direction of the housing 1.
[0042] It is understandable that, such as Figure 4 As shown, the first partition 41 is spaced apart from the front panel 14 of the housing 1 in the front-rear direction, and the second partition 42 is spaced apart from the top plate of the housing 1 in the vertical direction. The first partition 41, the second partition 42, and the inner wall of the housing 1 generally form a rectangular chamber structure. This allows for a more compact arrangement of components within the housing 1 and a higher space utilization rate.
[0043] like Figure 4 As shown, the side air outlet 13 is located on the side wall of the housing 1 and close to the front panel 14. In the projection plane orthogonal to the front and rear directions of the housing 1, the entire side air outlet 13 is located within the outer perimeter outline enclosed by the air guide cavity 43, thereby reducing the space occupied by the partition assembly 4 in the housing 1.
[0044] Optionally, such as Figure 4 and Figure 5 As shown, the centrifugal fan 3 includes a volute 31, which comprises a connected volute body 311 and a diffuser section 312. The volute body 311 is located behind the first partition 41, and the front end of the diffuser section 312 passes through the first partition 41 and extends into the air guide cavity 43. It can be understood that the impeller 32 of the centrifugal fan 3 is located inside the volute 31, and the volute 31 has an air intake on one axial side. The impeller 32 rotates inside the volute 31 to guide the heat exchange airflow into the diffuser section 312, and discharges it into the air guide cavity 43 through the exhaust port 3121.
[0045] like Figure 5 As shown, since the volute body 311 is located behind the first partition 41, the space behind the first partition can be fully utilized, allowing for a more compact arrangement of components within the housing 1. Because the front end of the diffuser section 312 passes through the first partition 41 and extends into the air guide cavity 43, the diffuser section 312 can guide the heat exchange airflow blown into the air guide cavity 43, allowing most of the heat exchange airflow to be discharged through the front air outlet 12, thus improving the overall airflow performance of the air conditioner.
[0046] Optionally, such as Figure 4 and Figure 5As shown, the heat exchanger 2 is located below the centrifugal fan 3 and the air guide cavity 43, and is arranged opposite to the air inlet 11. It can be understood that the airflow entering the casing 1 from the air inlet 11 passes through the heat exchanger 2 in an upward direction to exchange heat with the airflow. The heat-exchanged airflow is then drawn into the volute 31 by the centrifugal fan 3 and discharged into the air guide cavity 43 through the exhaust port 3121. Because the heat exchanger 2 is located between the centrifugal fan 3 and the air inlet 11, the arrangement of components within the casing 1 can be more rational.
[0047] In one example, such as Figure 4 and Figure 5 As shown, the heat exchanger 2 is a straight plate heat exchanger or an arc-shaped heat exchanger, and the heat exchanger 2 gradually extends downwards from front to back. The air conditioner also includes a water receiving tray 5, which is located inside the casing 1 and is located at the lower edge of the rear end of the heat exchanger 2. Due to the above-mentioned structural arrangement of the heat exchanger 2, the rear area inside the casing 1 can be used to accommodate the centrifugal fan 3, thus avoiding the installation of the centrifugal fan 3. Moreover, most of the heat exchange airflow can be integrated in the rear area of the casing 1 (i.e., the area where the centrifugal fan 3 is installed), which is beneficial to improving the heat exchange efficiency of the air conditioner.
[0048] like Figure 4 and Figure 5 As shown, the water receiving tray 5 is arranged at the lower edge of the rear end of the heat exchanger 2, and the water receiving tray 5 can collect the condensate on the fins of the heat exchanger 2. Optionally, the angle between the heat exchange wall surface of the heat exchanger 2 and the front-rear direction of the shell 1 is α, where 20°≤α≤50°. For example, α can be 20°, 30°, 35°, 40°, or 50°.
[0049] When α is too small (i.e., α is less than 20°), the condensate on heat exchanger 2 tends to drip vertically downwards under gravity, meaning the condensate on heat exchanger 2 is not easily guided along its inclined surface. When α is too large (i.e., α is greater than 50°), it results in a larger dimension of the air conditioner along its height, lower space utilization of components within the casing 1, and an unreasonable structure. Therefore, selecting α between 20° and 50° improves the heat exchanger's ability to guide condensate, reduces the likelihood of leaks in the air conditioner, and results in a more rational structural design and higher space utilization.
[0050] Optionally, such as Figure 1 and Figure 3 As shown, the air conditioner also includes a front air guide plate 6 and a side air guide plate 7. The front air guide plate 6 is rotatably mounted on the front air outlet 12, and the side air guide plate 7 is rotatably mounted on the side air outlet 13. It can be understood that the front air guide plate 6 can adjust the airflow direction of the front air outlet 12, and the side air guide plate 7 can adjust the airflow direction of the side air outlet 13. This increases the airflow range of the air conditioner and meets the needs of different users, thus improving the user experience.
