Also, as shown in fig. 6, in the first blowing mode, the air H blown out of the first main ventilation opening 131 flows along the ceiling T and descends along the opposite wall K of the indoor unit 10 of the air conditioner 1. Subsequently, the air H flows along the floor surface U, rises along the wall K of the indoor unit 10 provided with the air conditioner 1, and is sucked from the second ventilation opening 140.
As shown in fig. 7, in the indoor unit 10 of the air conditioner 1 of the present embodiment, the heat exchanger 300 is a condenser, the air filter is in the second filter position, both the first horizontal louver 150 and the first vertical louver 160 are in the open position, the first opening/closing portion 170 is in the open position, the second horizontal louver 180 is in the open position, and the air H is blown out from the second main vent 141 while the air H is being sucked from the first vent 130 at the time of the heating operation (in the second blowing mode). At this time, the second horizontal louver 180 can adjust the wind direction in the up-down direction. As shown in fig. 7, in the second blowing mode, the air H blown out from the second main ventilation opening 141 descends along the wall K and flows along the floor surface U. Subsequently, the air H rises along the wall K opposite to the indoor unit 10 of the air conditioner 1, flows along the ceiling T, and is sucked from the first ventilation opening 130.
When the indoor unit 10 of the air conditioner 1 is in heating operation, the first fan rotates at a high speed while the second fan rotates at a low speed. In addition, when the indoor unit 10 of the air conditioner 1 is in heating operation, the second fan rotates at a high speed while the first fan rotates at a low speed. That is, the indoor unit 10 of the air conditioner 1 can be switched between the cooling operation and the heating operation by using the heat exchanger 300 as an evaporator or a condenser and controlling the rotation speeds of the first fan and the second fan. That is, the flow direction of the air passing through the heat exchanger 300 may be reversed. In the present embodiment, the controller can control not only the first fan and the second fan to rotate at different rotational speeds, but also either the first fan or the second fan to stop rotating.
In the above manner, the indoor unit 10 of the air conditioner 1 of the present embodiment can operate both the first air blowing mode and the second air blowing mode, and the air direction can be adjusted regardless of whether the air outlet is the first air vent 130 or the second air vent 140, so that an air flow suitable for a cooling operation or an air flow for a heating operation can be generated in the indoor space. In addition, the area of the suction port can be enlarged regardless of whether the suction port is the first ventilation port 130 or the second ventilation port 140. A sufficient air volume can be obtained in either the cooling mode or the heating mode. Therefore, the air temperature distribution in the indoor space can be made uniform regardless of whether in the cooling mode or the heating mode.
The indoor unit 10 of the air conditioner 1 sucks air from the lower surface (second air inlet 140) and blows it out horizontally (first air inlet 130) during cooling operation, sucks air from the horizontal surface (second air inlet 140) and blows it out from the lower surface (second air inlet 140) during heating operation, and this reverse air flow can provide an air flow which does not feel supercooled by a user during cooling, and warm air can directly heat the floor during heating.
The invention provides an indoor unit of an air conditioner, wherein an upper guide part is arranged on the inner wall of an upper shell, namely the upper half part of the indoor unit of the air conditioner comprises the upper shell and the upper guide part; the drain pan and the lower guide part are arranged on the inner side of the bottom wall of the lower shell, namely the lower half part of the indoor unit of the air conditioner comprises the lower shell, the drain pan and the lower guide part; the upper and lower casing parts of the indoor unit of the air conditioner can be easily disassembled or assembled together due to the detachable and fixed connection of the upper and lower casing parts. In this way, the indoor unit can be conveniently mounted at a position where the space is narrow. In addition, if the first blower, the second blower or the heat exchanger needs to be maintained, the maintenance can be performed only by disassembling the half part, and the maintenance efficiency is improved.
While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that the foregoing is a further detailed description of the invention with reference to specific embodiments, and it is not intended to limit the practice of the invention to those descriptions. Various changes in form and detail may be made therein by those skilled in the art, including a few simple inferences or alternatives, without departing from the spirit and scope of the present invention.
