[0037] Embodiments of this disclosure are described in detail below, with examples of these embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting it.

[0038] like Figures 1 to 4 As shown, the air conditioner 100 of this embodiment includes a casing 1, an evaporator 2, an axial fan 3, and an air outlet duct 4. The lower part of the casing 1 has an air inlet 11, and the upper front side of the casing 1 has an air outlet 12. The evaporator 2, the axial fan 3, and the air outlet duct 4 are all disposed inside the casing 1. The axial fan 3 is disposed above the evaporator 2, and the air outlet duct 4 is disposed between the axial fan 3 and the air outlet 12. At least a portion of the air outlet duct 4 is arc-shaped and inclined upwards towards the air outlet 12.

[0039] The air conditioner 100 of this embodiment has an air inlet 11 at the lower part of the casing 1 and an air outlet 12 at the upper front of the casing 1. This allows indoor airflow to enter the air conditioner 100 through the air inlet 11, driven by an axial fan 3. After heat exchange with the evaporator 2, the airflow is guided by the air outlet duct 4 and flows out through the air outlet 12, providing cooling and heating effects to the room. It is understood that the axial fan 3 blows air vertically. By making at least a portion of the air outlet duct 4 arc-shaped and inclined upwards towards the air outlet 12, the airflow within the air outlet duct 4 can be guided to the air outlet 12.

[0040] Therefore, by utilizing the higher air pressure of the axial fan 3, the air delivery distance of the air conditioner 100 can be extended. Furthermore, the smaller overall size of the axial fan 3 improves the ease of assembly and disassembly.

[0041] Optionally, such as Figure 1 , Figure 3 and Figure 4 As shown, the air conditioner 100 also includes an air guide plate 9, which is movably disposed at the air outlet 12.

[0042] By setting an air guide plate 9 at the air outlet 12, the air outlet state of the air conditioner 100 can be controlled by moving the air guide plate 9, such as achieving horizontal air outlet, thereby continuously and stably providing comfortable cooling and heating effects for the room and improving the user experience.

[0043] In some embodiments, such as Figure 1 and Figure 2As shown, the air outlet duct 4 includes a first duct housing 401 and a second duct housing 402, with the first duct housing 401 located behind the second duct housing 402. Both the first duct housing 401 and the second duct housing 402 include an air intake section 41 and an air guide section 42, with the air guide section 42 located between the air intake section 41 and the air outlet 12. The air guide section 42 is in the shape of a convex arc with an upward protrusion.

[0044] By setting the air guide section 42 of the first air duct housing 401 and the second air duct housing 402 to an upwardly convex arc shape, the airflow can be facilitated to flow out from the air outlet 12 in a horizontal direction, thereby stably providing a comfortable cooling and heating effect for the room and improving the user experience of the air conditioner 100.

[0045] Optionally, such as Figure 2 As shown, the air guiding section 42 of the first air duct housing 401 includes a first convex arc section 4011, a second convex arc section 4012, and a third convex arc section 4013 connected sequentially from back to front. The lower end of the first convex arc section 4011 is tangent to the air intake section 41 of the first air duct housing 401, and the front end of the third convex arc section 4013 extends to the upper edge of the air outlet 12.

[0046] For example, such as Figure 2 As shown, the second convex arc segment 4012 is located in front of the first convex arc segment 4011, and the third convex arc segment 4013 is located in front of the second convex arc segment 4012, with the front end of the third convex arc segment 4013 extending to the upper edge of the air outlet 12.

[0047] By configuring the air guide section 42 of the first air duct housing 401 to include a first convex arc section 4011, a second convex arc section 4012, and a third convex arc section 4013 connected in sequence, the lower end of the first convex arc section 4011 is tangent to the air intake section 41 of the first air duct housing 401, and the front end of the third convex arc section 4013 extends to the upper edge of the air outlet 12. This reduces the flow resistance at the connection between the first convex arc section 4011 and the air intake section 41, as well as the flow resistance at the connection between the front end of the third convex arc section 4013 and the air outlet 12. Therefore, the flow resistance inside the air outlet duct 4 can be reduced, thereby increasing the air outlet speed of the air conditioner 100.

[0048] Optionally, such as Figure 2 As shown, the two ends of the second convex arc segment 4012 are tangent to the first convex arc segment 4011 and the third convex arc segment 4013, respectively.

[0049] For example, the rear end of the second convex arc segment 4012 is tangent to the first convex arc segment 4011, and the front end of the second convex arc segment 4012 is tangent to the third convex arc segment 4013.

[0050] By setting the two ends of the second convex arc segment 4012 to be tangent to the first convex arc segment 4011 and the third convex arc segment 4013 respectively, the flow resistance at the connection between the second convex arc segment 4012 and the first convex arc segment 4011, as well as the flow resistance at the connection between the second convex arc segment 4012 and the third convex arc segment 4013, can be reduced. This further reduces the flow resistance inside the air outlet duct 4, thereby increasing the air outlet speed of the air conditioner 100.

[0051] Optionally, the lower end of the air-guiding section 41 of the second air duct housing 402 is tangent to the air-guiding section 41 of the second air duct housing 402, and the upper end of the air-guiding section 42 of the second air duct housing 402 extends to the lower edge of the air outlet 12.

[0052] By tangenting the lower end of the guide section 42 of the second air duct housing 402 to the air intake section 41 of the second air duct housing 402, the flow resistance at the connection between the guide section 42 and the air intake section 41 of the second air duct housing 402 can be reduced; by extending the upper end of the guide section 42 of the second air duct housing 402 to the lower edge of the air outlet 12, the flow resistance at the connection between the air intake section 41 and the air outlet 12 of the second air duct housing 402 can be reduced. Therefore, the flow resistance inside the air outlet duct 4 can be further reduced, thereby increasing the air outlet speed of the air conditioner 100.

[0053] Optionally, the air intake section 41 of both the first air duct housing 401 and the second air duct housing 402 is a flat plate extending in the vertical direction.

[0054] It is understandable that the air supply direction of the axial flow fan 3 is along the vertical direction. By setting the air intake section 41 as a flat plate extending in the vertical direction, the flow resistance between the axial flow fan 3 and the air outlet duct 4 can be reduced, thereby increasing the air outlet speed of the air conditioner 100.

[0055] Optionally, such as Figures 1 to 4 As shown, the evaporator 2 includes multiple heat exchange sections 21 arranged sequentially along the front-to-back direction. The multiple heat exchange sections 21 are connected in sequence, and two adjacent heat exchange sections 21 are arranged in a V-shape.

[0056] For example, such as Figures 1 to 4 As shown, the evaporator 2 includes four heat exchange sections 21, and the evaporator 2 is W-shaped as a whole.

[0057] By configuring the evaporator 2 to include multiple heat exchange sections 21, with adjacent heat exchange sections 21 arranged in a V-shape, the heat exchange area of ​​the evaporator 2 can be increased within a limited space. This improves the heat exchange efficiency of the evaporator 2 and the efficiency of the air conditioner 100.

[0058] Of course, in other embodiments, the evaporator 2 can also be configured as other shapes such as U-shaped or V-shaped.

[0059] Optionally, such as Figure 2 and Figure 4 As shown, there are multiple axial flow fans 3, which are arranged at intervals along the left and right directions.

[0060] For example, there are three axial flow fans 3, which are arranged at intervals in the left and right directions.

[0061] By setting multiple axial flow fans 3, the air volume of the air conditioner 100 can be increased, thereby further improving the heat exchange efficiency of the air conditioner 100.

[0062] Optionally, the air conditioner 100 also includes a drip tray 5, which is disposed below the heat exchange section 21 and corresponding to the lower end of the heat exchange section 21. At least one drip tray 5 is used to collect condensate from two adjacent heat exchange sections 21.

[0063] By collecting the condensate from two adjacent heat exchange sections 21 with at least one drip tray 5, the number of drip trays 5 can be reduced, thereby lowering the cost of the air conditioner 100.

[0064] Optionally, the number of water receiving pans 5 is n, and the number of heat exchange sections 21 is 2n. Each water receiving pan 5 is used to receive the condensate from two adjacent heat exchange sections 21, where n is a positive integer greater than or equal to 1.

[0065] For example, there are two water receiving pans 5, which are arranged at intervals in the front-to-back direction. There are four heat exchange sections 21, which are connected in sequence in the front-to-back direction. The water receiving pan 5 located on the rear side is used to receive the condensate from the two heat exchange sections 21 located on the rear side, and the water receiving pan 5 located on the front side is used to receive the condensate from the two heat exchange sections 21 located on the front side.

[0066] By implementing the above design with water tray 5 and heat exchange section 21, the number of water trays 5 can be reduced while maintaining a large heat exchange area for evaporator 2.

[0067] Optionally, such as Figure 3 As shown, the vertical dimension of evaporator 2 is d1, where 80mm ≤ d1 ≤ 100mm. The thickness of heat exchange section 21 is d2, where 15mm ≤ d2 ≤ 35mm. The included angle between two adjacent heat exchange sections 21 is A, where 30° ≤ A ≤ 150°.

[0068] By setting the vertical dimension of the evaporator 2 to 80mm-100mm, the thickness of the heat exchange section 21 to 15mm-35mm, and the included angle between two adjacent heat exchange sections 21 to 30°-150°, the heat exchange area of ​​the evaporator 2 can be effectively increased, thereby improving the cooling and heating effect of the air conditioner 100.

[0069] Optionally, such as Figures 1 to 4As shown, the air conditioner 100 also includes an electric heating component 6, which is disposed on the upper side of the evaporator 2 and located between two adjacent heat exchange sections 21.

[0070] Among them, the electric heating component 6 can be a PTC heating component.

[0071] When the air conditioner 100 is in heating mode, the electric heating element 6 heats up, so that the airflow enters from the air inlet 11 under the drive of the axial fan 3 and is heated after flowing through the electric heating element 6, and then flows out from the air outlet 12 through the air outlet duct 4.

[0072] By setting up the electric heating component 6, the heating efficiency of the air conditioner 100 can be improved.

[0073] Optionally, such as Figures 1 to 4 As shown, the air conditioner 100 also includes a guide ring bracket 7, which is located inside the housing 1 and connected to the housing 1. The axial flow fan 3 is fixed inside the guide ring bracket 7.

[0074] When assembling the air conditioner 100, the axial fan 3 can be fixed inside the guide ring bracket 7 first, and then the guide ring bracket 7 can be connected to the casing 1, which facilitates the installation and fixing of the axial fan 3.

[0075] By setting the guide ring bracket 7, it is convenient to fix the axial flow fan 3 inside the housing 1, and further facilitate the disassembly and assembly of the axial flow fan 3.

[0076] Optionally, such as Figure 3 As shown, the distance between the upper part of the evaporator 2 and the lower part of the guide ring support 7 is d3, where 20mm≤d3≤40mm.

[0077] The distance between the upper part of the evaporator 2 and the lower part of the guide ring support 7 is set to 20mm to 40mm, which can effectively increase the heat exchange area of ​​the evaporator 2 and improve the cooling and heating effect of the air conditioner 100.

[0078] Optionally, such as Figure 1 and Figure 2 As shown, the housing 1 has a first protrusion 13 inside, and the lower part of the guide ring bracket 7 abuts against the first protrusion 13. The guide ring bracket 7 is connected to the first protrusion 13. The guide ring bracket 7 and the first protrusion 13 can be connected by screws.

[0079] For example, the front and rear sides of the housing 1 are provided with first protrusions 13, the front side of the flow guide ring bracket 7 is connected to the first protrusion 13 located on the front side, and the rear side of the flow guide bracket 7 is connected to the first protrusion 13 located on the rear side.

[0080] By setting a first protrusion 13 inside the housing 1, the air guide ring bracket 7 is connected to the first protrusion 13, which facilitates the connection and fixation of the air guide ring bracket 7 and the housing 1, thereby improving the assembly efficiency of the air conditioner 100.

[0081] Optionally, such as Figure 1 and Figure 2 As shown, the lower part of the air outlet duct 4 is provided with a second protrusion 43, which abuts against the upper part of the guide ring bracket 7 and is connected to the guide ring bracket 7.

[0082] For example, the lower part of the first air duct housing 401 and the second air duct housing 402 are both provided with a second protrusion 43. The second protrusion 43 of the first air duct housing 401 is connected to the rear side of the guide ring support 7, and the second protrusion 43 of the second air duct housing 402 is connected to the front side of the guide ring support 7.

[0083] By providing a second protrusion 43 at the lower part of the air outlet duct 4, and connecting the second protrusion 43 to the guide ring bracket 7, it is convenient to connect and fix the second protrusion 43 to the guide ring bracket 7, thereby improving the assembly efficiency of the air conditioner 100.

[0084] Optionally, the air inlet 11 is provided with an air inlet grille 8, and the distance between the upper part of the air inlet grille 8 and the lower part of the evaporator 2 is d4, 30mm≤d4≤50mm.

[0085] By setting the distance between the upper part of the air inlet grille 8 and the lower part of the evaporator 2 to 30mm to 50mm, the heat exchange area of ​​the evaporator 2 can be effectively increased, thereby improving the cooling and heating effect of the air conditioner 100.

[0086] The air conditioner 100 of this embodiment adopts a brand-new air outlet duct 4 and utilizes an axial flow fan 3 to extend the air delivery distance, thereby increasing the air delivery distance of the air conditioner 100. Simultaneously, the impeller size of the axial flow fan 3 is smaller, making installation and disassembly more convenient. The evaporator 2, comprising multiple heat exchange sections 21, increases the heat exchange area of ​​the evaporator 2, ensuring the cooling and heating effects of the air conditioner 100. Furthermore, the bottom air intake and top air outlet design effectively avoids direct cold air blowing, continuously providing cooling and heating effects to the room and improving the user experience.
