In the normal mode, as shown in fig. 6 and 7, the air mixing plate 4 is rotated to the first position, and the air mixing plate 4 abuts against the front plate 11 on the side facing the air mixing duct 7 to isolate the through-flow duct 5 from the air mixing duct 7; through the operation of the cross-flow fan 3, the heat exchange air flow which is subjected to heat exchange by the heat exchanger 8 is discharged into a room from the air outlet of the casing through the cross-flow air duct 5. The opening size and the opening direction of the air outlet of the shell can be adjusted by adjusting the rotation angle of the air deflector 2, so that the discharge direction of heat exchange air flow from the air outlet of the shell is adjusted.
In the heating and mixing mode, as shown in fig. 8 and 9, the air mixing plate 4 is communicated with the through-flow air duct 5 and the air mixing air duct 7, and the air mixing plate 4 rotates to the second position, through the operation of the through-flow fan 3, the heat exchange air flow in the through-flow air duct 5 is discharged from the air outlet of the casing, so that negative pressure is formed in the through-flow air duct 5, outdoor air enters the through-flow air duct 5 through the air mixing air duct 7 by the air mixing opening 111 and the side plate air opening 131 under the action of the negative pressure and is mixed with the heat exchange air flow to form air conditioning air, and the air conditioning air is discharged into a room from the air outlet of the casing under the operation of the through-flow fan 3. Because the air-conditioning wind is formed by mixing the heat exchange airflow with higher temperature and the indoor air with lower temperature, the temperature of the air-conditioning wind is between the indoor air and the mixed hot airflow, and the temperature of the air-conditioning wind is higher than that of the indoor air, the air-conditioning wind floats upwards relative to the indoor air when being discharged, and the air-conditioning wind 4 and the air deflector 2 form an extension air duct together by inclining the end of the air-mixing wind deflector 4 far away from the connecting plate 62 and the end of the air deflector 2 far away from the bottom plate 15 downwards, so that the air-conditioning wind downwards discharges the air-conditioning indoor unit along the extension air duct, the ascending path of the air-conditioning wind is prolonged, the heat exchange time of the air-conditioning wind and the indoor air is prolonged, and the air-conditioning wind can fully exchange heat with the indoor air.
In the cooling mixing mode, as shown in fig. 10 and 11, the air mixing plate 4 is communicated with the through-flow air duct 5 and the air mixing air duct 7 and rotates to a third position, heat exchange air in the through-flow air duct 5 is discharged from the air outlet of the casing through the operation of the through-flow air fan 3, so that negative pressure is formed in the through-flow air duct 5, outdoor air enters the through-flow air duct 5 through the air mixing air duct 7 by the air mixing air duct 111 and the side plate air opening 131 under the action of the negative pressure and is mixed with the heat exchange air to form air conditioning air, and the air conditioning air is discharged into a room from the air outlet of the casing under the operation of the through-flow air fan 3. Because the air-conditioning wind is formed by mixing heat exchange airflow with lower temperature and indoor air with higher temperature, the temperature of the air-conditioning wind is between the indoor air and the mixed hot airflow, and the temperature of the air-conditioning wind is lower than that of the indoor air, the air-conditioning wind can sink towards the opposite indoor air when being discharged, and the air-conditioning wind is upwards discharged out of the air-conditioning indoor unit by arranging one end of the air deflector 2 far away from the bottom plate 15 along the horizontal direction or upwards in an inclined manner, so that the sinking path of the air-conditioning wind is prolonged, the heat exchange time of the air-conditioning wind and the indoor air is prolonged, the air-conditioning wind can fully exchange heat with the indoor air, and the air-conditioning wind with lower temperature is prevented from directly blowing the human body; it should be noted that, the end of the air-mixing plate 4 far away from the connecting plate 62 extends into the air-mixing duct 7 and is disposed upwards, so as to prevent the air-mixing plate 4 from blocking the air-conditioning air and reduce the air volume of the air-conditioning air discharged from the air outlet of the casing.
The air conditioner indoor unit is provided with the air mixing duct 7, and the air mixing duct 7 is provided with the air mixing opening 111 so as to introduce indoor air into the interior of the machine shell and mix the indoor air with heat exchange air flow in the through-flow duct 5 to form air conditioner air, so that overheated or supercooled air is prevented from being discharged from the air outlet of the machine shell; the air mixing wind plate 4 is arranged to communicate or isolate the air mixing wind channel 7 and the through-flow wind channel 5, so that the indoor unit of the air conditioner can have various working modes, thereby meeting the diversified demands of users; by arranging the inner panel 61, the inner panel 61 is matched with the connecting plate 62 to divide the interior of the shell into the air mixing duct 7 and the through-flow duct 5; and the front plate 11 is provided with a mixing air port 111 to increase the mixing air quantity of the mixing air duct 7, so that the mixing air quantity can be increased according to the needs of users.
