[0032] 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.

[0033] like Figures 1 to 5 As shown, the air conditioner 100 of this embodiment includes a casing 1, a plurality of axial flow fans 3, a plurality of air outlet ducts, and a plurality of air guide assemblies 9. The axial flow fans 3 and the air outlet ducts are both disposed within the casing 1. The air outlet ducts are disposed between the axial flow fans 3 and the air outlet 12, and the air guide assemblies 9 are disposed at the air outlet 12. Each air outlet duct corresponds to at least one axial flow fan 3, and each air guide assembly 9 corresponds to one air outlet duct. Each axial flow fan 3 and each air guide assembly 9 are independently controlled.

[0034] Each axial fan 3 is independently controlled, meaning that the user can control the on / off state and power of each axial fan 3 as needed, thereby controlling the airflow in the outlet duct corresponding to that axial fan 3. Each air guide assembly 9 is also independently controlled, meaning that the user can control the position of each air guide assembly 9 as needed, thereby controlling the airflow direction at the outlet 12 corresponding to that air guide assembly 9.

[0035] The air conditioner 100 of the embodiments of the present disclosure is provided with the air inlet 11 at the lower part of the casing 1 and the air outlet 12 at the upper part of the front side of the casing 1, so that the airflow in the room can enter the air conditioner 100 through the air inlet 11 under the driving of the axial flow fan 3, and then flow out through the air outlet 12 after heat exchange in the air conditioner 100, thereby providing the cooling and heating effects to the room. Since the air pressure of the axial flow fan 3 is high, the air supply distance of the air conditioner 100 can be extended. By arranging each air outlet channel corresponding to at least one axial flow fan 3, the air guide assembly 9 is arranged corresponding to the air outlet channel one by one, and each axial flow fan 3 and each air guide assembly 9 can be controlled individually, so that the axial flow fan 3 and the air guide assembly 9 corresponding to different air outlet channels can be controlled as needed, thereby controlling the air supply state of different areas in the air conditioner 100 and meeting the needs of users for different air feeling experiences.

[0036] In some embodiments, as shown in Figure 1 and Figure 2 The air conditioner 100 further comprises a plurality of air outlet air ducts 4, the air outlet air ducts 4 surround the air outlet channel, and at least a part of the air outlet air ducts 4 is arranged in a direction inclined to the air outlet 12 along the downward direction.

[0037] It can be understood that the air supply direction of the axial flow fan 3 is along the upward and downward direction, and the air outlet 12 is located above the air inlet in the front direction, and the airflow flowing along the upward and downward direction needs to be changed to flow along the front direction by using the air outlet channel.

[0038] By arranging at least a part of the air outlet air duct 4 in a direction inclined to the air outlet 12 along the downward direction, the airflow in the air outlet channel can be guided to the air outlet 12 and flow out in the front direction through the air outlet 12, thereby improving the ability of the air conditioner 100 to not directly blow the airflow.

[0039] Optionally, as shown in Figure 3 and Figure 4 The air outlet air duct 4 comprises an air duct inlet 41, an air guide section 42 and an air duct outlet 43, the air duct inlet 41 is in communication with the fan outlet of the axial flow fan 3, the air duct outlet 43 is in communication with the air outlet 12, and the air guide section 42 is arranged between the air duct inlet 41 and the air duct outlet 43. The air guide section 42 is arranged in a direction inclined to the air outlet 12 along the downward direction.

[0040] By arranging the air guide section 42 in a direction inclined to the air outlet 12 along the downward direction, the airflow in the air outlet channel is changed by the air guide section, thereby improving the ability of the air conditioner 100 to not directly blow the airflow.

[0041] Optionally, as shown in Figures 1 to 4 The air guide section 42 is arranged in a convex arc shape protruding upward.

[0042] By setting the air guide section 42 as a convex arc shape protruding upward, the air flow is facilitated to flow out of the air outlet 12 in a horizontal direction, thereby stably providing comfortable cooling and heating effects for the indoor space and improving the user experience of the air conditioner 100.

[0043] Optionally, the shape of the air duct inlet 41 is circular, and the shape of the air duct outlet 43 is rectangular.

[0044] It can be understood that the shape of the fan outlet of the axial flow fan 3 is generally circular, and the shape of the air outlet 12 is generally rectangular. Therefore, by setting the shape of the air duct inlet 41 as circular and the shape of the air duct outlet 43 as rectangular, the communication between the axial flow fan 3 and the air outlet 12 is facilitated by using the air outlet duct 4.

[0045] Optionally, the distance from the center of the air duct outlet 43 to the lower end of the air outlet passage is H, the diameter of the air duct inlet 41 is D, and the ratio of H to D is 0.3-1.

[0046] Experimental studies show that when the ratio of H to D is greater than 1, the overall height of the air outlet duct 4 is too high, resulting in an overall height of the air conditioner 100 being too large. When the ratio of H to D is less than 0.3, the pressure of the air flow in the air outlet passage impacting the upper surface of the air outlet duct 4 is relatively large, resulting in the air flow in the air outlet passage being difficult to flow out in a horizontal direction.

[0047] By setting the ratio of H to D to be 0.3-1, the air flow at the air outlet 12 of the air conditioner 100 can be ensured to flow out in a horizontal direction, improving the ability of the air conditioner 100 to blow air flow horizontally, and the overall height of the air conditioner 100 can be avoided from being too large, which is conducive to reducing the volume of the air conditioner 100.

[0048] Optionally, as shown in Figure 5 , the cabinet 1 includes an air outlet area 13, which is arranged between the axial flow fan 3 and the air outlet 12. The air outlet area 13 is provided with a partition plate 10, which divides the air outlet area 13 into a plurality of air outlet passages.

[0049] For example, as shown in Figure 5 , two partition plates 10 are arranged in the air outlet area 13, and the two partition plates 10 are arranged in the left-right direction and divide the air outlet area into three air outlet passages arranged in the left-right direction.

[0050] By arranging the partition plate 10 in the air outlet area 13 of the cabinet 1, the air outlet area 13 is divided into a plurality of air outlet passages by the partition plate 10, which is conducive to simplifying the structure of the air conditioner 100 and reducing the cost of the air conditioner 100.

[0051] Optionally, as shown in Figure 2 and Figure 5As shown, the air outlet channels are arranged one-to-one with the axial flow fans 3. The plurality of axial flow fans 3 are arranged at intervals in the left-right direction, and the plurality of air outlet channels are arranged at intervals in the left-right direction.

[0052] For example, the number of air outlet channels and axial flow fans 3 is three, the three axial flow fans 3 are arranged at intervals in the left-right direction, and the three air outlet channels are arranged at intervals in the left-right direction.

[0053] By arranging the air outlet channels one-to-one with the axial flow fans 3, the layout and installation of the air outlet channels and the axial flow fans 3 are facilitated.

[0054] Optionally, the air guide assembly 9 includes a first air guide plate 91 and a second air guide plate 92, the first air guide plate 91 being configured to control the air outlet direction of the air outlet 12 in the left-right direction, and the second air guide plate 92 being configured to control the air outlet direction of the air outlet 12 in the up-down direction.

[0055] The first air guide plate 91 can swing in the left-right direction to control the air outlet direction of the air outlet 12 in the left-right direction, and the second air guide plate 92 can swing in the up-down direction to control the air outlet direction of the air outlet 12 in the up-down direction.

[0056] By providing the air guide assembly 9 with the first air guide plate 91 and the second air guide plate 92, the air outlet direction of the air outlet 12 in the up-down direction and the left-right direction can be controlled by the first air guide plate 91 and the second air guide plate 92, facilitating the user to control the air outlet direction of the air outlet 12 according to the needs, and better meeting the user's needs.

[0057] The air conditioner 100 further includes a first drive motor and a second drive motor, the first drive motor being connected with the first air guide plate 91 to drive the first air guide plate 91 to move, and the second drive motor being connected with the second air guide plate 92 to drive the second air guide plate 92 to move.

[0058] The first drive motor is used to drive the first air guide plate 91 to move, and the second drive motor is used to drive the second air guide plate 92 to move, facilitating the movement of the first air guide plate 91 and the second air guide plate 92 to be controlled respectively.

[0059] As shown in Figure 1 , Figure 2 and Figure 5 , the air conditioner 100 further includes an evaporator 2 and a water pan 5, the axial flow fan 3 is arranged on the upper side of the evaporator 2, and the water pan 5 is arranged on the lower side of the evaporator 2, the water pan 5 being configured to receive the condensed water generated by the evaporator 2.

[0060] As shown in Figure 2 and Figure 5 , the evaporator 2 includes a plurality of heat exchange sections 21 arranged in sequence in the front-rear direction, the plurality of heat exchange sections 21 are connected in sequence, and adjacent two heat exchange sections 21 are arranged in a V shape.

[0061] For example, the evaporator 2 includes four heat exchange sections 21, and the evaporator 2 as a whole is in a W shape.

[0062] By arranging the evaporator 2 to include multiple heat exchange sections 21 and arranging two adjacent heat exchange sections 21 in a V shape, the heat exchange area of the evaporator 2 can be increased in a limited space. Thus, the heat exchange efficiency of the evaporator 2 can be improved, and the efficiency of the air conditioner 100 can be improved.

[0063] Of course, in other embodiments, the evaporator 2 can also be arranged in a U shape, a V shape, or other shapes. The lower side of the evaporator 2 corresponds to the lower end of the heat exchange section 21.

[0064] As shown in FIGS. 1, 2, and 3, the air conditioner 100 further includes at least one water collecting tray 5. Figure 2 Figure 4 As shown in FIGS. 1, 2, and 3, the air conditioner 100 further includes at least one water collecting tray 5.

[0065] By arranging the at least one water collecting tray 5 to collect the condensed water of two adjacent heat exchange sections 21, the number of water collecting trays 5 can be reduced, and the cost of the air conditioner 100 can be reduced.

[0066] Optionally, the number of water collecting trays 5 is n, the number of heat exchange sections 21 is 2n, and each water collecting tray 5 is arranged to collect the condensed water of two adjacent heat exchange sections 21, where n is a positive integer greater than or equal to 1.

[0067] For example, the number of water collecting trays 5 is two, the two water collecting trays are arranged in the front-rear direction, the number of heat exchange sections 21 is four, the four heat exchange sections 21 are sequentially connected in the front-rear direction, the water collecting tray 5 on the rear side is arranged to collect the condensed water of the two heat exchange sections 21 on the rear side, and the water collecting tray 5 on the front side is arranged to collect the condensed water of the two heat exchange sections 21 on the front side.

[0068] By arranging the water collecting tray 5 and the heat exchange section 21 as described above, the heat exchange area of the evaporator 2 can be increased while the number of water collecting trays 5 is reduced.

[0070] The electric heating assembly 6 can be a PTC heating assembly.

[0071] When the air conditioner 100 is in a heating mode, the electric heating assembly 6 is heated, so that the airflow entering the air inlet 11 under the driving of the axial flow fan 3 can be heated after flowing through the electric heating assembly 6, and then flows out of the air outlet 12 through the air outlet air duct 4.

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