The air mixing duct 1c is communicated with the heat exchange duct 1a through a communication port 1g, and the communication port 1g is positioned at the downstream side of the fan component 2, so that air flow in the heat exchange duct 1a firstly flows through the fan component 2 and then flows through the communication port 1g; when the heat exchange air flow of the heat exchange air duct 1a flows through the communication port 1g, at least part of the heat exchange air flow of the heat exchange air duct 1a can flow to the air mixing air duct 1c through the communication port 1g, and the air mixing air duct 1c is communicated with the outlet 1d of the fresh air duct 1b, then the heat exchange air flow and the fresh air flow can be mixed in the air mixing air duct 1c, when the fresh air function is started by the air conditioning indoor unit 100 and the second air outlet 1f is air-out, the difference between the fresh air flow blown out from the second air outlet 1f and the indoor temperature can be reduced, or when the first air outlet 1e and the second air outlet 1f are air-out, the temperature difference between the fresh air flow blown out from the second air outlet 1f and the heat exchange air flow blown out from the first air outlet 1e can be reduced, the temperature difference between the fresh air flow blown out from the second air outlet 1f and the fresh air outlet 1e can be easily caused, and the temperature difference between the fresh air flows to different indoor positions can be avoided, thereby improving the comfort of the fresh air outlet of the air conditioning indoor unit 100, the indoor temperature control can be easily realized, the uniformity of the indoor temperature control of the air conditioning indoor unit 100 can be improved, the user can be improved, and the comfort of the air conditioning indoor unit can be improved, and the air flow of the heat exchange air flow can be accelerated by the heat exchange air flow from the second air outlet 1f and the fresh air flow can be mixed in the indoor air circulation air duct 1.

For example, in the example of fig. 10, the housing 1 is further formed with an air inlet 1h, the air inlet 1h is located at the upstream side of the fan component 2 and the heat exchange component 3, the fan component 2 includes a cross flow wind wheel 21, the heat exchange component 3 includes a heat exchanger 31, in the airflow direction, the heat exchange component 3 is located between the air inlet 1h and the cross flow wind wheel 21, the cross flow wind wheel 21 rotates to drive airflow in the heat exchange air duct 1a to flow, and the airflow enters the heat exchange air duct 1a from the air inlet 1h and passes through the heat exchange component 3 to exchange heat and then flows through the cross flow wind wheel 21; when the fresh air function of the indoor unit 100 of the air conditioner is started and both the first air outlet 1e and the second air outlet 1f are used for air outlet, part of heat exchange air flow in the heat exchange air duct 1a is blown out from the first air outlet 1e, the other part of heat exchange air flow enters the air mixing air duct 1c through the communication port 1g and is mixed with fresh air flow flowing to the air mixing air duct 1c from the fresh air duct 1b, and mixed air flow (including fresh air flow and heat exchange air flow) is blown out from the second air outlet 1f.

Illustratively, when the indoor unit 100 is used for heating, the heat exchanger 31 serves as a condenser, the temperature of the heat exchange air flow is higher than that of the fresh air flow, and part of the heat exchange air flow can flow to the air mixing duct 1c through the communication port 1g to be mixed with the fresh air flow flowing to the air mixing duct 1c from the fresh air duct 1b, so as to improve the fresh air comfort.

According to the air conditioning indoor unit 100 of the embodiment of the utility model, the air mixing duct 1c is communicated with the heat exchange duct 1a through the communication port 1g, and then part of heat exchange air in the heat exchange duct 1a can flow to the air mixing duct 1c through the communication port 1g, so that the heat exchange air and fresh air are mixed in the air mixing duct 1c, the temperature of the mixed air blown out from the second air outlet 1f is appropriate, the temperature difference between the fresh air blown out from the fresh air duct 1b and the heat exchange air in the heat exchange duct 1a is avoided to be larger, the comfort of fresh air outlet of the air conditioning indoor unit 100 is improved, and the experience of a user is improved.

In some embodiments, as shown in fig. 6 to 10, the air conditioning indoor unit 100 further includes a wind mixing switch door 4, where the wind mixing switch door 4 is movably disposed at the communication port 1g to switch the communication port 1g, so as to control the closing and opening of the communication port 1g, thereby controlling whether the heat exchange air flow in the heat exchange air duct 1a enters the wind mixing air duct 1c to be mixed with the fresh air flow, enriching the operation modes of the air conditioning indoor unit 100, so as to adapt to different requirements of users, and facilitate the operation of the users.

It can be understood that when the indoor unit 100 of the air conditioner only opens the heat exchange air duct 1a, as shown in fig. 7, the air mixing switch door 4 closes the communication port 1g, so as to avoid that part of the heat exchange air flow of the heat exchange air duct 1a enters the air mixing air duct 1c to affect the flow rate and the air flow rate of the heat exchange air flow of the first air outlet 1e, thereby ensuring the normal operation of the heat exchange air duct 1a to realize indoor air circulation and adjusting the indoor temperature, and at this time, the fan component 2 and the heat exchange component 3 are both operated, the first air outlet 1e is used for air outlet, and the second air outlet 1f is not used for air outlet; when the air conditioner indoor unit 100 only opens the fresh air duct 1b, as shown in fig. 8, the air mixing switch door 4 closes the communication port 1g, so as to prevent the fresh air flow of the fresh air channel from flowing into the heat exchange duct 1a through the air mixing duct 1c to affect the flow rate and the air flow rate of the fresh air flow of the second air outlet 1f, so that outdoor fresh air enters the room to improve the indoor air quality, at this time, the fan component 2 and the heat exchange component 3 are not operated, the second air outlet 1f is used for air outlet, and the first air outlet 1e is not used for air outlet; when the heat exchange air duct 1a and the fresh air duct 1b are opened by the air conditioner indoor unit 100, as shown in fig. 10, the communication port 1g is opened by the air mixing switch door 4, so that part of heat exchange air flows to the air mixing air duct 1c through the communication port 1g to be mixed with fresh air of the fresh air duct 1b, so that the temperature difference between the mixed air and the heat exchange air is reduced, direct blowing of users by the supercooled or overheated fresh air compared with the heat exchange air is avoided, and the experience of the users is improved; when the air conditioner indoor unit 100 opens the heat exchange air duct 1a and the fresh air duct 1b, as shown in fig. 9, the air mixing switch door 4 may also close the communication port 1g, and the heat exchange air flow cannot flow to the air mixing air duct 1c through the communication port 1g, and the heat exchange air flow and the fresh air flow are blown out through different air outlets respectively.

Alternatively, the mixing switch door 4 is controlled to move by a driving motor.

In some embodiments, as shown in fig. 5 and 10, the air mix switch door 4 is rotatably provided at the communication port 1g, and opposite ends of the air mix switch door 4 in the air flow direction are an upstream end 4a and a downstream end 4b, respectively. Wherein the downstream end 4b is rotatably connected with the housing 1, and the upstream end 4a is adapted to rotate toward the inside of the heat exchange air duct 1a to open the communication port 1g; alternatively, the upstream end 4a is rotatably connected to the housing 1, and the downstream end 4b is adapted to rotate toward the outside of the heat exchange air duct 1a to open the communication port 1g. Therefore, when the communication port 1g is opened by the air mixing switch door 4, the air mixing switch door 4 can guide part of heat exchange air flow of the heat exchange air duct 1a to flow to the air mixing air duct 1c to be mixed with fresh air flow of the fresh air duct 1b, so that the temperature difference between the mixed air flow and the heat exchange air flow of the heat exchange air duct 1a is reduced, and the comfort of a user is improved.

For example, in the example of fig. 10, when the heat exchange airflow in the heat exchange air duct 1a enters from the air inlet 1h and is blown out from the first air outlet 1e after passing through the heat exchange component 3 and the fan component 2, the communication port 1g is located at the downstream side of the fan component 2 in the flowing direction of the heat exchange airflow, the downstream end 4b is rotationally connected with the housing 1, and in the airflow direction, the downstream end 4b of the air mixing switch door 4 is closer to the first air outlet 1e than the upstream end 4a, when the upstream end 4a of the air mixing switch door 4 rotates relative to the downstream end 4b to deflect the air mixing switch door 4 by a certain angle towards the first air outlet 1e, that is, the upstream end 4a rotates towards the inside of the heat exchange air duct 1a, the communication port 1g is opened by the air mixing switch door 4, and the opening direction of the air mixing switch door 4 faces the flowing direction of the heat exchange airflow towards the air mixing air duct 1c, so that the heat exchange airflow and the air flow of the air duct 1b can be better guided, and the air flow of the air mixing duct can be more evenly, and the temperature deviation of the air mixing air flow can be better improved, and the user experiences are facilitated. In some embodiments, as shown in fig. 5 and fig. 10, the opening of the air mixing switch door 4 is adjustable, and the opening of the communication port 1g can be adjusted to adjust the air flow entering the air mixing duct 1c in the heat exchange duct 1a, so as to ensure that a proper amount of heat exchange air flow flows into the air mixing duct 1c to be mixed with fresh air flow, effectively reduce the temperature difference between the mixed air flow and the heat exchange air flow, and ensure that the temperature of the mixed air flow blown to a user is proper. In addition, if the air conditioning indoor unit 100 has a plurality of different wind speed gears, the opening degree of the air mixing switch door 4 can be adjusted, so that the flow rate of different heat exchange air flows can be adapted to change the air flow rate entering the air mixing duct 1c.

In some embodiments, as shown in fig. 10, the outlet 1d and the communication port 1g of the fresh air duct 1b are respectively located at different sides of the air mixing duct 1c, so that the air flow direction at the outlet 1d of the fresh air duct 1b and the air flow direction at the communication port 1g form a non-zero included angle, so that the fresh air flow and the heat exchange air flow in the air mixing duct 1c are better mixed with each other, the fresh air flow and the heat exchange air flow are better mixed uniformly, the temperature of the mixed air flow is prevented from being uneven, and the air outlet comfort of the indoor unit 100 of the air conditioner is further improved.

The outlet 1d of the fresh air duct 1b is located at the end of the air mixing duct 1c in the second direction, so that fresh air flows along the second direction or flows along the direction inclined to the second direction, and heat exchange air flowing into the communication port 1g can flow towards the second air outlet 1f, so that the heat exchange air and the fresh air flow are better mixed in the heat exchange duct 1a, and meanwhile, the heat exchange air drives the fresh air flow to flow towards the second air outlet 1f, so that mixed air flows from the second air outlet 1f to the indoor, thereby being beneficial to accelerating fresh air efficiency of indoor air and improving indoor air quality.

For example, in the examples of fig. 5 and 10, the second air outlet 1f is located at the lower side of the first air outlet 1e, the first air outlet 1e is communicated with the heat exchange air duct 1a, the second air outlet 1f is communicated with the air mixing air duct 1c, the outlet 1d of the fresh air duct 1b is located at the left end of the air mixing air duct 1c, the outlet 1d of the fresh air duct 1b faces the right air outlet, the communication port 1g is located at the upstream side of the first air outlet 1e, part of the heat exchange air flow enters the air mixing air duct 1c through the communication port 1g and flows in the direction of the second air outlet 1f, the heat exchange air flow and the fresh air flow are mixed in the air mixing air duct 1c, and the heat exchange air flow drives the fresh air flow to flow toward the second air outlet 1f, so that the mixed air flow toward the second air outlet 1f is blown to the user.
