The first air inlet 11 is communicated with the outdoor space, and the air supply outlet 16, the second air inlet 12 and the third air inlet 13 are communicated with the indoor space.
In the indoor unit of an air conditioner provided in this embodiment, the third air inlet 13 is not provided with a switch, so that the second air compartment is always kept in a conduction state with the indoor space. No matter whether the fresh air mode is started or not, the second air chamber uses an indoor air circulation mode so as to ensure the basic functions (refrigeration, heating or air supply and the like) of the indoor unit of the air conditioner. When the fresh air exchange function is started, the first switch 14 is opened, the second switch 15 is closed, the first air inlet 11 is communicated, the second air inlet 12 is closed, the first air chamber is communicated with the outdoor space, outdoor air can be sucked into the first air chamber and finally sent into the room through the air supply opening 16, and the fresh air exchange function is achieved.

Correspondingly, in combination with the above, the first subspace is a first air chamber, and the second subspace is a second air chamber. The air supply assembly 3 is disposed in the second space, and the air supply opening 16 is disposed at a lower portion of the housing 1 and is communicated with the second space. It is to be noted that the heat exchanger 2 merely divides the first space and the second space, but does not seal the first space and the second space from each other. That is, the air introduced into the first space can be introduced into the second space through the gap of the heat exchanger 2, and finally discharged from the air outlet 16. I.e. the air entering the first and second air chambers, can both enter the second space through the gaps of the heat exchanger 2 and finally be discharged from the supply air outlet 16.

Meanwhile, the first partition plate is provided to prevent air in the first air chamber from entering the second air chamber. Taking cooling in summer as an example, the second air chamber sucks indoor air, then is cooled by the heat exchanger 2, enters the second space and is discharged from the air supply outlet 16. When the fresh air exchange function is started, the first air chamber is communicated with the outdoor space, and the outdoor temperature is higher than the indoor temperature, so that the temperature of the sucked outside air is also higher than the temperature of the sucked air in the second air chamber. If the air in the first air chamber enters the second air chamber, the overall temperature of the air in the second air chamber is increased, and at this time, under the condition that the power of the heat exchanger 2 is not changed, the air passing through the heat exchanger 2 is higher than the previous temperature, so that the customer experience is reduced. In order to reduce the influence on the temperature of the output air as much as possible, in this embodiment, a first partition plate is provided to prevent the air in the first air chamber from entering the second air chamber, so that the two air chambers are independent from each other and do not interfere with each other.

Further, referring to fig. 4-7, in the present embodiment, a second partition plate is further disposed inside the casing 1, the second partition plate is disposed at a lower side of the heat exchanger 2, and the second partition plate cooperates with an inner side wall of the casing 1 to divide the second space into a third subspace and a fourth subspace. Specifically, the left side of the second partition board is a third subspace, and the right side of the second partition board is a fourth subspace. Meanwhile, the third subspace is communicated with the first subspace, the fourth subspace is communicated with the second subspace, the third subspace and the fourth subspace are communicated with the air supply opening 16, and the air supply assembly 3 is arranged in the third subspace and the fourth subspace at the same time. That is, the air entering the first air chamber enters the third subspace after passing through the gap of the heat exchanger 2, and is discharged from the air supply outlet 16; the air entering the second air chamber passes through the gap of the heat exchanger 2, enters the fourth subspace and is discharged from the air supply outlet 16. In this embodiment, through setting up the second baffle, make first plenum and second plenum discharge the air in the second space still keep the separate state, prevent that two kinds of air of different temperatures from mixing in the second space, influencing the air-out effect, guarantee customer experience as far as. Specifically, the second partition plate is composed of a third plate body 23 and a fourth plate body 24, the third plate body 23 is directly connected with the lower surface of the heat exchanger 2, the fourth plate body 24 is connected with the inner wall of the shell 1, and after installation, the third plate body 23 and the fourth plate body 24 are spliced to form the second partition plate, so that the third subspace and the fourth subspace are isolated. The air supply outlet 16 has the same form as the air supply outlet 16 in the existing room, is arranged at the lower half part of the shell 1, is in a long strip shape, and is communicated with the third subspace and the fourth subspace.

In this embodiment, the driver 33 may be a motor.
Because the first air chamber and the second air chamber use the same heat exchanger 2, the power for heat exchange is the same. However, after the fresh air exchange function is started, the temperatures of the air sucked by the first air chamber and the second air chamber are different, so that the temperatures of the air blown out from the third subspace and the fourth subspace are different to a certain extent, and the user experience is influenced to a certain extent. In order to ensure the efficiency of exchanging fresh air and ensure the experience of customers as much as possible, in this embodiment, the ratio a of the volume of the first subspace to the volume of the second subspace is 1/1-1/7.
