Because there may be substances such as dust and even other solid particles in the outdoor new trend, need carry out purification treatment when outdoor new trend is introduced indoorly to prevent to cause the influence to indoor environment, reduce the cleanliness of indoor foul smell. As shown in fig. 1 to 6, an air purifying module is disposed in the first air duct 51 to purify air entering the second air duct 11 from the first air duct 51; the air purification module is installed on the purification frame 3 so as to set the air purification mode in the first air duct 51; since the air purification module needs to be periodically cleaned, replaced or overhauled, in order to facilitate the installation and disassembly of the air purification module, the purification frame 3 is detachably installed in the first air duct 51; the top of the fresh air shell is provided with a mounting opening 22, and the purifying frame 3 is inserted into the mounting opening 22 so as to mount the purifying frame 3 in the first air duct 51; when the purifying frame 3 is disassembled, the purifying frame 3 is pulled out from the mounting opening 22; the cleaning frame 3 is installed in the first air duct 51 in a plugging manner, so that the cleaning frame 3 can be conveniently installed and detached; it should be noted that the working principle of the air purification module for purifying air belongs to the common knowledge technology in the field, and is not described herein again.

In practical application, indoor foul air sometimes needs to be purified, but outdoor fresh air does not need to be introduced, and in order to solve the technical problem, as shown in fig. 7, the purification frame 3 divides the first air duct 51 into a first chamber 512 and a second chamber 513, the first chamber 512 and the second chamber 513 are arranged in parallel and communicated with each other, the first chamber 512 is communicated with the outdoor, the fresh air opening 511 is arranged in the first chamber 512, and the second chamber 513 is communicated with the second air duct 11. The air passes through the air purification module when entering the second chamber 513 from the first chamber 512, therefore, if the air passes through the first chamber 512 and the second chamber 513 in sequence and then enters the second air duct 11, the air entering the second air duct 11 is clean air purified by the air purification module, and if the air directly enters the second air duct 11 from the second chamber 513, the air entering the second air duct 11 is not purified by the air purification module; as shown in fig. 8, the fresh air housing opening 23 is divided into a first opening 231 and a second opening 232 by the purification frame 3, the first opening 231 is disposed in the first chamber 512, the second opening 232 is disposed in the second chamber 513, indoor foul air is introduced into the first chamber 512 from the first opening 231 through the operation of the fresh air blower 8, enters the second chamber 513 after being purified by the air purification module, and then flows into the room from the fresh air outlet 111 through the second air duct 11, so that indoor foul air can be purified, during the indoor foul air purification process, the outdoor fresh air can be prevented from entering the first air duct 11 from the fresh air opening 511 by opening the second switching module 9, if the second switching module 9 is closed, outdoor fresh air is also introduced into the first chamber 512 from the fresh air outlet 511 while indoor foul air is introduced into the first chamber 512 from the first opening 231 through the operation of the fresh air blower 8, at this time, the air in the first chamber 512 is a mixture of outdoor fresh air and indoor foul air, and the mixture enters the second chamber 513 after being purified by the air purification module, and the fresh air flows into the indoor air outlet 111 through the second air duct 11; therefore, when purifying indoor foul air, the air conditioner can only purify the indoor foul air, and can also purify introduced outdoor fresh air when purifying the indoor foul air.

When indoor foul air is purified and outdoor fresh air is not introduced, as shown in fig. 3, 5, 12 and 16, the controller controls the fresh air fan 8 to work and controls the first motor 41 to drive the first baffle 43 to slide in the slide way 451 to the first position, so as to open the first air port 231 and close the second air port 232; controlling the second motor 92 to drive the second baffle 91 to rotate to an open state, so that the fresh air opening 511 of the first air duct 51 is separated from the fresh air shell air opening 23, and the first air duct 51 is communicated with the third air duct 12; meanwhile, the third motor 72 drives the third baffle 71 to rotate to a closed state, so that the second air duct 11 and the third air duct 12 are separated, indoor foul air is introduced into the first chamber 512 from the first air inlet 231 through the operation of the fresh air fan 8, and the foul air flows into the room from the fresh air outlet 111 through the second chamber 513 and the second air duct 11 after being purified by the air purification module, so that the air conditioner enters a self-purification mode.

The air output of the fresh air mode is adjusted by adjusting the rotation angle of the third baffle 71, when the third baffle 71 rotates between the open state and the closed state, although the second air duct 11 and the third air duct 12 are both in the half-open state, the air originally flowing into the room from the fresh air outlet 111 of the second air duct 11 may enter the third air duct 12, but because the second baffle 91 is in the closed state and the first air duct 51 is separated from the third air duct 12, the air entering the third air duct 12 cannot flow, and therefore, the operation of the air conditioner in the fresh air mode cannot be affected by adjusting the rotation angle of the third baffle 71 to adjust the air output of the second air duct 11.

The air output of the self-purification mode is adjusted by adjusting the size of the air opening of the first air opening 231, but cannot be adjusted by adjusting the rotation angle of the third baffle 71, because in the self-purification mode, the second baffle 91 is in the closed state, at this time, the first air duct 51 is communicated with the third air duct 12, if the third baffle 71 is rotated to the position between the open state and the closed state, the second air duct 11 and the third air duct 12 are both in the half-open state, the air originally flowing into the room from the fresh air outlet 111 of the second air duct 11 may enter the third air duct 12, at this time, the third air duct 12 is communicated with the first air duct 51, and the air in the third air duct 12 flows into the room from the fresh air opening 511, so that the adjustment of the air output of the second air duct 11 by adjusting the rotation angle of the third baffle 71 affects the operation of the air conditioner in the self-purification mode, and thus, the air output of the air conditioner in the self-purification mode adjusts the size of the air opening of the first air opening 231.

The air output of the air exhaust mode is adjusted by adjusting the size of the second air opening 232; in the air mixing mode, the mixing ratio of the indoor foul air and the outdoor fresh air in the first cavity 512 and the air output in the air mixing mode can be adjusted by adjusting the size of the first air opening 231.

The air conditioner can switch among a fresh air mode, an air exhaust mode, a self-purification mode and a mixed air mode by controlling the first motor 41, the second motor 92 and the third motor 72 through the controller so as to meet various requirements of users on indoor foul air, and the switching efficiency is high; the air output of the fresh air mode can be adjusted by adjusting the rotation angle of the third baffle 71, the air output of the self-purification mode, the mixing ratio of indoor foul air and outdoor fresh air in the first cavity 512 in the air mixing mode and the air output of the air mixing mode can be adjusted by adjusting the size of the air opening of the first air opening 231, the air output of the air exhaust mode can be adjusted by adjusting the size of the air opening of the second air opening 232, and the air output in each working mode can be adjusted so that the air conditioner can better meet the requirements of users.
