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.

[0028] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation 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.

[0029] 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.

[0030] This application provides a ceiling machine, such as Figures 1-9 As shown, the ceiling air conditioner includes a housing, a water collection tray 200, and an annular air outlet 300. The housing includes a chassis 110, which is disposed opposite to the water collection tray 200. The annular air outlet 300 is located between the chassis 110 and the water collection tray 200. The two axial ends of the annular air outlet 300 are respectively connected to the chassis 110 and the water collection tray 200. The side wall of the annular air outlet 300 is provided with multiple ventilation openings 301.

[0031] The ceiling air conditioner provided in this application embodiment has an annular air outlet 300 between the chassis 110 and the water collection tray 200. The side wall of the annular air outlet 300 is provided with multiple ventilation holes 301. The two axial ends of the annular air outlet 300 are respectively connected to the chassis 110 and the water collection tray 200, thereby suspending and fixing the water collection tray 200 below the annular air outlet 300. That is, the outer periphery of the water collection tray 200 is not connected to the outer periphery of the machine casing. This eliminates the original connection structure around the water collection tray 200 and the corners, effectively reducing the obstruction of the airflow around the water collection tray 200 and the corners, thereby increasing the actual air volume of the ceiling air conditioner and helping to achieve a full-area surround air outlet effect, resulting in better comfort.

[0032] It is understandable that, since the ceiling machine of this application eliminates the original connection structure around the water tray 200 and at the corners, the overall weight and cost of the ceiling machine can be reduced, while the types and quantities of assembly parts can be reduced, thus improving assembly efficiency.

[0033] In some embodiments of this application, the two axial ends of the annular air outlet 300 are detachably connected to the chassis 110 and the water receiving tray 200, respectively. That is, one axial end of the annular air outlet 300 is detachably connected to the chassis 110, and the other axial end of the annular air outlet 300 is detachably connected to the water receiving tray 200. By detachably connecting one axial end of the annular air outlet 300 to the chassis 110, the annular air outlet 300 can be removed from the chassis 110 for maintenance or replacement. By detachably connecting the other axial end of the annular air outlet 300 to the chassis 110, the annular air outlet 300 can be separated from the water receiving tray 200 for maintenance or replacement.

[0034] Optionally, one axial end of the annular air outlet 300 is screwed to the chassis 110; or, one axial end of the annular air outlet 300 is snapped to the chassis 110.

[0035] Optional, combined Figure 7 , Figure 8 and Figure 9As shown, one end edge of the annular air outlet 300 is provided with a groove 302, and the edge of the water receiving tray 200 is provided with a snap-fit ​​protrusion 210, which engages with the groove 302. By setting the annular air outlet 300 and the water receiving tray 200 to engage with each other through the snap-fit ​​protrusion 210 and the groove 302, the installation and disassembly of the annular air outlet 300 and the water receiving tray 200 are facilitated, thereby improving the efficiency of installation and disassembly.

[0036] Specifically, one end edge of the annular air outlet 300 is provided with multiple slots 302, which are arranged at intervals along the circumference of the annular air outlet 300; the edge of the water receiving tray 200 is provided with multiple snap-fit ​​protrusions 210, which are arranged at intervals along the circumference of the water receiving tray 200, and the multiple snap-fit ​​protrusions 210 are snap-fitted into the multiple slots 302 in a one-to-one correspondence.

[0037] In some embodiments of this application, such as Figure 9 As shown, the annular air outlet 300 has a first flange 310 and a second flange 320 at its two axial ends. The first flange 310 is connected to the chassis 110, and the second flange 320 abuts against the water receiving tray 200. By providing the first flange 310 and the second flange 320, this application allows the first flange 310 to facilitate the connection between the annular air outlet 300 and the chassis 110, while also improving the fit between them. The second flange 320 ensures that the edge of the annular air outlet 300 fits snugly against the upper surface of the water receiving tray 200, thereby improving the fit between them. The upper surface can be understood as the surface above the ceiling-mounted unit in the height direction during operation.

[0038] Specifically, such as Figure 5 and Figure 6 As shown, the chassis 110 is provided with a first connecting hole 111, and the first flange 310 of the annular air outlet 300 is provided with a second connecting hole. The first connecting hole 111 and the second connecting hole are connected by screws, that is, the first flange 310 of the annular air outlet 300 is connected to the chassis 110 by screws.

[0039] In some embodiments of this application, such as Figure 9As shown, the vent 301 is a strip-shaped vent (i.e., the vent 301 is strip-shaped), extending along the axial direction of the annular air outlet 300. By setting the vent 301 as a strip-shaped vent extending along the axial direction of the annular air outlet 300, this application, while ensuring the structural strength of the annular air outlet 300, facilitates controlling the distance between the two vents 301 to be as small as possible, so as not to obstruct airflow and affect air volume; at the same time, it can also make the distance between the two vents 301 more uniform, thereby improving the overall structural strength of the annular air outlet 300, and the strip-shaped vent is easier to manufacture. For example, the vent 301 can be a rectangular vent 301.

[0040] Optionally, the number of vents 301 can be 35 to 60. Without affecting the overall structural strength of the annular air outlet 300, the number of vents 301 can be as large as possible to enable the airflow to be quickly and evenly distributed into the ceiling unit, thereby improving the overall performance of the ceiling unit.

[0041] Optionally, the number of vents 301 is odd. An odd number of vents 301 can prevent the annular air outlet 300 from fatigue due to resonance during the operation of the ceiling machine, which could lead to breakage of the annular air outlet 300, thereby improving the performance of the ceiling machine.

[0042] In some embodiments of this application, multiple vents 301 are evenly spaced along the circumference of the annular air outlet 300. This arrangement allows the airflow generated during the operation of the fan 400 to be more evenly distributed into the ceiling unit through the vents 301 of the annular air outlet 300, significantly improving the overall performance of the ceiling unit. In addition, the even distribution of airflow within the ceiling unit through the vents 301 effectively avoids abnormal noise caused by collisions due to concentrated airflow, thereby enhancing the user experience.

[0043] Optionally, the material of the annular air outlet 300 is not limited. For example, in some embodiments, the annular air outlet 300 is made of plastic, such as ABS plastic or HIPS (high impact polystyrene) injection molded.

[0044] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the housing of the ceiling air conditioner also includes a panel 120 and side panels 130 around the perimeter. The chassis 110 and the side panels 130 around the perimeter form an accommodating cavity with an opening. The panel 120 closes the opening. The water receiving tray 200 and the annular air outlet 300 are both disposed in the accommodating cavity.

[0045] Specifically, the panel 120 is positioned opposite the chassis 110. The panel 120 has an air inlet and an air outlet 121, with the air outlet 121 surrounding the air inlet. The air inlet is connected to the annular air outlet 300, and the water collection tray 200 is located between the air inlet and the air outlet 121 and surrounds the air inlet. The air inlet is used to allow air to enter the ceiling-mounted unit, and the multiple air outlets 121 are used to allow air to exit the ceiling-mounted unit. The water collection tray 200 has a ventilation hole 202 in the middle that communicates with both the air inlet and the annular air outlet 300, and the water collection trough 201 is arranged around the ventilation hole 202.

[0046] Optional, such as Figure 1 As shown, a grille 122 can be installed at the air inlet, so that the incoming airflow passes through the grille 122 first, and then enters the interior of the annular air outlet 300. Optionally, an air guide plate 123 is provided at the air outlet 121. The air guide plate 123 is used to adjust the outflow direction of the airflow, so that the airflow is smoother.

[0047] Optionally, the air outlet 121 may include multiple sub-air outlets, which are arranged at intervals along the circumference of the air inlet to achieve the effect of the air outlet 121 surrounding the air inlet. Alternatively, the air outlet 121 may be annular, with the annular air outlet 121 surrounding the outer periphery of the air inlet. This also achieves the effect of the air outlet 121 surrounding the air inlet, and the annular air outlet 121 facilitates a full-area surround airflow effect, resulting in better comfort.

[0048] In some embodiments of this application, such as Figures 2-4 As shown, the ceiling-mounted air conditioner also includes a fan 400 and a heat exchanger 500. The fan 400 is mounted on the chassis 110, and an annular air outlet 300 surrounds the fan 400. The heat exchanger 500 surrounds the annular air outlet 300. By arranging the annular air outlet 300 around the fan 400 and the heat exchanger 500 around the annular air outlet 300, the airflow from the air inlet can fully contact the heat exchanger 500 after flowing out of the vent 301 of the annular air outlet 300, thus improving heat exchange efficiency and enhancing the performance of the ceiling-mounted air conditioner.

[0049] Specifically, when the ceiling unit is installed on the ceiling, the chassis 110 is located above the drip tray 200. The annular air outlet 300, the fan 400, and the heat exchanger 500 are all located between the chassis 110 and the drip tray 200. The fan 400 is installed on the chassis 110. The annular air outlet 300 surrounds the fan 400, and the heat exchanger 500 surrounds the annular air outlet 300. The drip tray 200 is used to collect the condensate dripping from the heat exchanger 500.

[0050] The fan 400 may include axial fan blades and a motor for driving the axial fan blades to rotate, with the motor fixed to the chassis 110. When the motor starts, it drives the axial fan blades to rotate, thereby causing airflow to enter the housing through the air inlet on the panel 120. Then, the airflow enters the interior of the annular air outlet 300 through the ventilation hole 202 of the water tray 200, and then flows out from the ventilation port 301 of the annular air outlet 300 to the heat exchanger 500 for heat exchange. After heat exchange in the heat exchanger 500, the airflow flows to the air outlet 121 on the panel 120 and is finally blown out from the air outlet 121.

[0051] In some embodiments of this application, such as Figure 8 As shown, the water receiving tray 200 forms a water receiving groove 201 with the groove opening facing upwards. The lower end of the heat exchanger 500 is clamped within the water receiving groove 201, and the upper end of the heat exchanger 500 abuts against the base plate 110. The upward-facing water receiving groove 201 facilitates the collection of condensate dripping from the heat exchanger 500. During assembly, the lower end of the heat exchanger 500 is first inserted into the water receiving groove 201 through the groove opening, clamping it within the groove. Then, the upper end of the heat exchanger 500 is abutted against the base plate 110, allowing for quick and stable assembly of the heat exchanger 500. The "upper end" can be understood as the upper end in the vertical direction when the ceiling-mounted unit is in use, and the "lower end" is the lower end in the vertical direction when the ceiling-mounted unit is in use.

[0052] In the prior art, the heat exchanger 500 of a ceiling-mounted air conditioner typically consists of two rows of heat exchangers 500, which are usually connected and fixed together using fixing hooks. This assembly is relatively cumbersome. Since the fixing hooks are sheet metal parts and are directly clipped onto the fins of the heat exchanger 500, they can affect the fins over time, thereby affecting the performance of the heat exchanger 500. However, this application achieves the fixation of the heat exchanger 500 by clamping the lower end of the heat exchanger 500 into the water receiving tank 201. This eliminates the need for existing fixing hooks, preventing them from affecting the heat exchanger 500 during the operation of the ceiling-mounted air conditioner. It also reduces the types and number of assembly parts, improves assembly efficiency, and reduces the overall cost of the ceiling-mounted air conditioner.

[0053] Optionally, the height of the annular water receiving tank 201 can be 3mm to 10mm, for example, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, or 10mm, etc., which can be set according to actual needs. By setting the height of the annular water receiving tank 201 within the range of 3mm to 10mm, this application can not only ensure effective clamping of the heat exchanger 500 and prevent the heat exchanger 500 from moving, but also help control material costs.

[0054] Optional, such as Figure 4As shown, a buffer element 600 is provided between the heat exchanger 500 and the inner surface of the water receiving tank 201. By providing the buffer element 600 between the heat exchanger 500 and the inner surface of the water receiving tank 201, friction between the heat exchanger 500 and the water receiving tank 201 can be prevented, thus preventing damage to the heat exchanger 500 and affecting its performance. Specifically, the buffer element 600 can be a sponge or other material that can provide cushioning.

[0055] This application also provides an air conditioner, which includes a ceiling unit. The specific structure of the ceiling 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, and will not be described in detail here.

[0056] In some embodiments of this application, the air conditioner also includes an outdoor unit, which is connected to the ceiling unit via a connecting pipe.

[0057] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0058] The ceiling-mounted air conditioner and air conditioner provided in the embodiments of this application have been described in detail above.
