In an embodiment, referring to fig. 8, a setting height H2 of a bottommost end a5 of the air outlet 10a is lower than a setting height H3 of a top end a4 of a side wall of the water receiving tray 40 near the air outlet 10a, when the wind guiding water guiding device 52 is at the first wind guiding position, a tail end of the wind guiding water blocking device 52 along the wind guiding direction extends out of the water receiving tray 40, and when the wind guiding water blocking device 52 is at the second wind guiding position, a tail end of the wind guiding water blocking device 52 along the wind guiding direction is connected with a top end a4 of a side wall of the water receiving tray 40 near the air outlet 10a, so that the setting height H2 of the bottommost end a5 of the air outlet 10a is lower than the setting height H3 of the top end a4 of the side wall of the water receiving tray 40 near the air outlet 10a, and the side wall of the housing 10 below the air outlet 10a can be prevented from blocking the wind guiding device 52 due to processing errors and/or assembly errors.
In an embodiment, referring to fig. 7 and 8, when the indoor unit of the air duct is in the high-windshield cooling state, the air guiding and water blocking member 52 is in the first air guiding position.
Specifically, the air pipe indoor unit generally has three modes of a high windshield, an intermediate windshield and a low windshield, the air outlet speed of the high windshield is the highest, the air outlet speed of the low windshield is the lowest, and the air outlet speed of the intermediate windshield is between the high windshield and the low windshield, so that the air guide water piece 52 can be driven to rotate to the first air guide position with the highest setting height in the refrigeration high windshield state, thereby not only meeting the air outlet requirement, but also preventing the condensed water in the water collector 40 from being blown out from the air outlet 10 a.
In an embodiment, referring to fig. 10 and fig. 11, when the indoor unit of the air duct is in the cooling low damper state, the air guiding and water blocking member 52 is in the second air guiding position. Because the air outlet speed of the low windshield is lowest, when the air pipe indoor unit is in a refrigeration low windshield state, the air guide water piece 52 can be driven to rotate to the second air guide position with the lowest set height, so that the air guide and water retaining are met, the effective air outlet height H1 at the air outlet 10a can be increased, the effective air outlet area is increased, and the air outlet comfort can be further improved.
In one embodiment, when the indoor unit of the air duct is in the cooling intermediate air guiding state, the air guiding shutter 52 can be driven to rotate to a position between the first air guiding position and the second air guiding position.
In an embodiment, referring to fig. 10 and fig. 11, when the indoor unit of the air duct is in a heating state, the air guide water baffle 52 is in the second air guide position. When the air pipe indoor unit is in a heating state, no condensate water is generated on the heat exchanger assembly 30, therefore, no matter the air pipe indoor unit is in a high windshield, a medium windshield or a low windshield in the heating state, the air guide water retaining piece 52 can be in the second air guide position, therefore, the effective air outlet area can be increased, and the comfort of air outlet is improved.
The various embodiments/implementations provided herein can be combined with each other without contradiction.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application are included in the protection scope of the present application.
