[0027] Another embodiment of the present application provides an air conditioner, including the air conditioner indoor unit described above.

[0028] Another embodiment of the present application provides an air conditioning control method for the above-mentioned air conditioner, the method comprising:

[0029] Determining an air outlet mode of the air conditioner;

[0030] If the air outlet mode is the normal air outlet mode, the partition is controlled to be in the storage position, and the first fan and the second fan are controlled to operate;

[0031] If the air outlet mode is a single-side air outlet mode, the partition is controlled to be in the separation position, and the first fan or the second fan is controlled to operate according to a set control strategy.

There is almost no cross-wind phenomenon between the first air duct and the second air duct, and the air outlet effect in the single-side air outlet mode is also good. It can be seen that by setting a separation component, the air conditioner indoor unit of the embodiment of the present application can have a good air outlet effect in multiple air outlet modes.

[0051] An embodiment of the present application provides an air conditioner. Figure 1 , the air conditioner includes an air conditioner indoor unit.

[0052] See also Figures 1 to 7 The air conditioner indoor unit includes a housing 10 and a partition assembly 20 , a first fan 30 and a second fan 40 .

[0053] The housing 10 is provided with an air inlet 10a, a first air outlet 10b and a second air outlet 10c. A wind passage 10d, a first air duct 10e and a second air duct 10f are provided in the housing 10. The first air duct 10e and the second air duct 10f are located on the side of the wind passage 10d away from the air inlet 10a.

[0054] The first air duct 10e is communicated with the first air outlet 10b, and the second air duct 10f is communicated with the second air outlet 10c.

[0055] The air inlet 10a is the entrance for the external air flow to enter the shell 10, the first air outlet 10b is the outlet for the air flow in the first air duct 10e to flow out of the shell 10, and the second air outlet 10c is the outlet for the air flow in the second air duct 10f to flow out of the shell 10.

[0056] The air passage space 10d is a space through which the airflow passes after entering the housing 10 from the air inlet 10a and before entering the first air duct 10e or the second air duct 10f.

[0057] A heat exchanger 70 is disposed in the housing 10 of the air conditioner indoor unit. The heat exchanger 70 includes a heat exchange body 71 and a delivery pipe connected to the heat exchange body 71 . The delivery pipe is used for the refrigerant to flow into or out of the heat exchange body 71 .

[0058] For example, see Figure 1 The heat exchange body 71 can be arranged between the air inlet 10a and the wind passing space 10d, that is, after the airflow enters the shell 10 from the air inlet 10a, it first passes through the heat exchange body 71, and after heat exchange at the heat exchange body 71, it enters the wind passing space 10d.

[0059] Please continue reading Figures 1 to 7 The partition assembly 20 includes a partition plate 21 and a driving mechanism 22 ( Figures 1 to 5 The air conditioner indoor unit shown does not show the driving mechanism 22, and the driving mechanism 22 drives the partition plate 21 to move so that the partition plate 21 can be switched between the storage position and the separation position.

[0060] That is to say, the partition 21 is a movable structure, and the partition 21 can move under the drive of the driving mechanism 22, thereby realizing the switching between the storage position and the separation position.

[0061] The driving mechanism 22 drives the partition 21 to move in any manner. For example, the driving mechanism 22 can drive the partition 21 to rotate so that the partition 21 can switch between the storage position and the separation position. The driving mechanism 22 can also drive the partition 21 to move horizontally so that the partition 21 can switch between the storage position and the separation position.

[0062] The driving mechanism 22 includes a driving motor. According to different driving modes, the driving motor can directly drive the partition 21 to move, or the driving mechanism 22 can be further provided with a transmission component, and the driving motor drives the transmission component to move, so that the transmission component drives the partition 21 to move.

[0063] See also Figure 1 , Figure 2 and Figure 6 When the partition 21 is in the storage position, the air inlet 10a is connected to the first air duct 10e and the second air duct 10f respectively through the wind passage space 10d.

[0064] That is, when the partition plate 21 is in the storage position, the airflow flowing into the housing 10 from the air inlet 10a directly passes through the wind space 10d and flows into the first air duct 10e and the second air duct 10f respectively.

[0065] See also Figures 3 to 5 , Figure 7 When the partition 21 is in the separation position, the partition 21 divides the wind passage space 10d into a first wind passage 10d1 connecting the air inlet 10a and the first air duct 10e and a second wind passage 10d2 connecting the air inlet 10a and the second air duct 10f.

[0066] That is to say, part of the airflow flowing from the air inlet 10a into the wind space 10d enters the first wind duct 10e from the first wind passage 10d1, and the other part of the airflow enters the second wind duct 10f from the second wind passage 10d2. The airflow flowing from the air inlet 10a into the housing 10 is divided into two paths at the wind space 10d. For the convenience of description, the two paths can be respectively referred to as the first airflow path and the second airflow path, wherein the first airflow path passes through the first wind passage 10d1, the first wind duct 10e and the first air outlet 10b, and the second airflow path passes through the second wind passage 10d2, the second wind duct 10f and the second air outlet 10c.

[0067] The main difference between the separation position and the storage position is that when the partition 21 is in the separation position, the wind space 10d will be divided into the first wind channel 10d1 and the second wind channel 10d2 by the partition 21, while when the partition 21 is in the storage position, the wind space 10d will not be divided into the first wind channel 10d1 and the second wind channel 10d2.

[0068] It should be noted that the partition 21 is not limited to having only a separation position and a storage position. In some embodiments, the driving mechanism 22 can also drive the partition 21 to move to other positions. For example, the partition 21 can also have an initial position. The driving mechanism 22 can drive the partition 21 from the initial position to the separation position, and can also drive the partition 21 from the initial position to the storage position. In other words, the switching of the partition 21 between the separation position and the storage position only means that the driving mechanism 22 can drive the partition 21 to move to the separation position or the storage position, rather than that the partition 21 can only move between the separation position and the storage position.

[0069] Please continue reading Figure 2 The first fan 30 drives the airflow to flow along the first air duct 10e, and the second fan 40 drives the airflow to flow along the second air duct 10f.

[0070] Specifically, the air conditioner indoor unit can be set to a normal air outlet mode and a single-side air outlet mode. In the normal air outlet mode, both the first fan 30 and the second fan 40 are turned on to drive the air to flow along the first air duct 10e and the second air duct 10f respectively. In the single-side air outlet mode, only one of the first fan 30 and the second fan 40 is turned on. For example, when the first fan 30 is turned on, the airflow mainly flows along the first air duct 10e, and when the second fan 40 is turned on, the airflow mainly flows along the second air duct 10f.

[0071] It should be noted that, in the single-sided air outlet mode, a small amount of airflow will also flow into the air duct where the fan is not turned on. For example, when only the first fan 30 is turned on, a large amount of airflow flows into the first air duct 10e driven by the first fan 30, but a small amount of airflow still flows into the second air duct 10f. Similarly, when only the second fan 40 is turned on, a large amount of airflow flows into the second air duct 10f driven by the second fan 40, but a small amount of airflow still flows into the first air duct 10e.

[0072] Another embodiment of the present application provides an air conditioning control method, which is used for the air conditioner provided by any embodiment of the present application. Figure 8 , the method comprises the following steps:

[0073] Step S101: determining the air outlet mode of the air conditioner;

[0074] Step S102: If the air outlet mode is the normal air outlet mode, the partition is controlled to be in the storage position, and the first fan and the second fan are controlled to operate;

[0075] Specifically, controlling the partition to be in the storage position means that if the partition is in the storage position before entering the normal air outlet mode, then after entering the normal air outlet mode, the partition is still in the storage position; if the partition is not in the storage position before entering the normal air outlet mode, then after entering the normal air outlet mode, it is necessary to control the operation of the driving mechanism to drive the partition to move to the storage position.

[0076] The first fan and the second fan may be operated simultaneously, or one of them may be controlled to operate first and then the other one may be controlled to operate.

[0077] When the partition needs to move to the storage position, the three steps of controlling the operation of the driving mechanism, controlling the operation of the first fan and controlling the operation of the second fan are performed in no particular order.

[0078] Step S103: If the air outlet mode is the single-side air outlet mode, the partition is controlled to be in the separation position, and the first fan or the second fan is controlled to operate according to the set control strategy.

[0079] Specifically, controlling the partition to be in the separation position means that if the partition is in the separation position before entering the single-sided air outlet mode, then after entering the single-sided air outlet mode, the partition is still in the separation position; if the partition is not in the separation position before entering the single-sided air outlet mode, then after entering the single-sided air outlet mode, it is necessary to control the operation of the driving mechanism to drive the partition to move to the separation position.

[0080] When the partition needs to move to the separation position, the steps of controlling the driving mechanism to operate and controlling the first fan or the second fan to operate are performed in no particular order.

[0081] That is to say, the partition position of the partition is mainly used for the single-sided air outlet mode. In the single-sided air outlet mode, the partition divides the air passage space into a first air passage and a second air passage, and controls the operation of the first fan or the second fan according to the set control strategy.

[0082] Exemplarily, controlling the operation of the first fan or the second fan according to the set strategy may include the following manner: determining whether to start the first fan, and if so, controlling the first fan to start, and if not, controlling the second fan to start.

[0083] That is to say, if it is determined that the first fan needs to be started, the first fan is turned on. If it is determined that the first fan does not need to be started, it is equivalent to assuming that the second fan needs to be started. In this case, the second fan is turned on.

[0084] In some embodiments, the method of controlling the operation of the first fan or the second fan according to the set strategy may also be to determine whether to start the second fan, and if so, control the second fan to start, and if not, control the first fan to start. Alternatively, the method of controlling the operation of the first fan or the second fan according to the set strategy may also be to control the first fan to start upon receiving a control signal for controlling the operation of the first fan; and control the second fan to start upon receiving a control signal for controlling the operation of the second fan.

[0085] Also, see Figures 1 to 7 A first air guide plate 80 may be provided at the first air outlet 10b, and a second air guide plate 90 may be provided at the second air outlet 10c. In the single-side air outlet mode, if the first fan is turned on, the first air guide plate is opened, and if the second fan is turned on, the second air guide plate is opened.

[0086] In the related art, the indoor unit of the air conditioner generally sets a partition structure between the two air ducts to separate the two air ducts. However, the two air ducts separated from each other can actually only prevent the cross-wind between the two air ducts in the single-side air outlet mode. In the normal air outlet mode, that is, when the two fans are running at the same time, the airflow will flow into the corresponding air ducts respectively under the action of the two fans. Therefore, in the normal air outlet mode, there is no problem of cross-wind. In the related art, the partition structure separating the two air ducts is fixed inside the indoor unit of the air conditioner. That is to say, no matter what air outlet mode the indoor unit of the air conditioner is in, the two air ducts are always separated. When the two fans are running at the same time, part of the faster airflow will hit the partition structure, which is equivalent to the partition structure having a certain obstruction effect on the airflow flowing to the two air ducts, thereby causing the indoor unit of the air conditioner to have problems such as large air intake resistance, low air volume, and high noise.

[0087] The air-conditioning indoor unit of the embodiment of the present application is provided with a partition assembly 20 having a partition 21 and a driving mechanism 22. The driving mechanism 22 drives the partition 21 to move, so that the partition 21 can be switched between a storage position and a partition position. When the partition 21 is in the storage position, the air inlet 10a is connected to the first air duct 10e and the second air duct 10f respectively through the wind space 10d; when the partition 21 is in the partition position, the partition 21 divides the wind space 10d into a first wind channel 10d1 connecting the air inlet 10a and the first air duct 10e and a second wind channel 10d2 connecting the air inlet 10a and the second air duct 10f. In the normal air outlet mode when the first fan 30 and the second fan 40 are both in operation, the partition 21 can be in the storage position, and the airflow flowing into the shell 10 from the air inlet 10a directly passes through the wind space 10d and flows into the first air duct 10e and the second air duct 10f respectively without being blocked by the partition 21. In other words, the airflow can flow smoothly in the wind space 10d, thereby reducing the air intake resistance, increasing the air volume, and effectively reducing the noise, thereby improving the air outlet effect in the normal air outlet mode. When the single-side air outlet mode is required, the partition 21 can be in the separation position, and the partition 21 separates the first air duct 10e from the second air duct 10f. If the first fan 30 is turned on at this time, a large amount of airflow flows into the first air duct 10e through the first air passage 10d1 under the action of the first fan 30. If the second fan 40 is turned on at this time, a large amount of airflow flows into the second air duct 10f through the second air passage 10d2 under the action of the second fan 40. There is almost no cross-wind phenomenon between the first air duct 10e and the second air duct 10f, and the air outlet effect in the single-side air outlet mode is also good. It can be seen that by setting the partition component 20, the air conditioner indoor unit of the embodiment of the present application can have a good air outlet effect in multiple air outlet modes.

[0088] In one embodiment, please refer to Figures 1 to 7The air conditioner indoor unit may be provided with a first air housing 50 and a second air housing 60 in the housing 10. The first air housing 50 defines a first air duct 10e, and the second air housing 60 defines a second air duct 10f. An end of the first air housing 50 close to the air passing space 10d and an end of the second air housing 60 close to the air passing space 10d are arranged at a distance, so that an installation space 10g communicating with the air passing space 10d is formed at the distance, and the partition 21 may be installed in the installation space 10g.

[0089] The driving mechanism 22 may be disposed in the installation space 10g or outside the installation space 10g.

[0090] That is, an installation space 10g for accommodating the partition 21 may be provided between the first wind shell 50 and the second wind shell 60, and the installation space 10g is close to the wind passing space 10d, thereby facilitating the partition 21 to switch between the separation position and the storage position.

[0091] For example, see Figure 1 , one end of the first wind shell 50 close to the wind passing space 10d and one end of the second wind shell 60 close to the wind passing space 10d can be deflected in directions away from each other to form the installation space 10g.

[0092] That is to say, one end of the first wind shell 50 close to the wind space 10d and one end of the second wind shell 60 close to the wind space 10d can be deflected in two opposite directions respectively, so that the first wind shell 50 and the second wind shell 60 can form a separation space at the deflected position, and the separation space is the installation space 10g.

[0093] One end of the first wind shell 50 close to the wind passage space 10d and the other end of the second wind shell 60 close to the wind passage space 10d are respectively deflected in directions away from each other, so that the entrance of the first air duct 10e and the entrance of the second air duct 10f can be directed toward the air inlet 10a from different directions, respectively. In this way, the airflow flowing into the shell 10 from different positions of the air inlet 10a can flow into the first air duct 10e and the second air duct 10f respectively, and the first wind shell 50 and the second wind shell 60 can also play a certain guiding role on the airflow, so that the airflow can flow into the first air duct 10e and the second air duct 10f more smoothly.

[0094] In addition, after one end of the first wind shell 50 close to the wind passage space 10d and the other end of the second wind shell 60 close to the wind passage space 10d are deflected in directions away from each other, the interval space formed by the first wind shell 50 and the second wind shell 60 at the deflected position is actually an idle area. Therefore, by using this area as the installation space 10g, the space inside the shell 10 can be fully utilized, so that the partition assembly 20 can be arranged more compactly inside the shell 10.

[0095] For the rotating partition 21, in one embodiment, please refer to Figures 1 to 5 The partition 21 can be rotatably installed in the installation space 10g. When the partition 21 is in the storage position, the partition 21 is located in the installation space 10g. That is, the partition 21 can be stored in the installation space 10g to minimize the partition 21 from obstructing the airflow flowing into the wind space 10d in the normal air outlet mode.

[0096] Please continue reading Figures 3 to 5 , Figure 7 Under the drive of the driving mechanism 22, the partition 21 enters the wind passage space 10d by rotation, and the partition 21 switches to the separation position.

[0097] For further information, see Figures 1 to 5 The installation space 10g can be separated into an installation groove 10g1 communicating with the wind passing space 10d, and the installation groove 10g1 is located at the junction of the wind passing space 10d and the installation space 10g. When the partition 21 is in the storage position, the partition 21 is located in the installation groove 10g1.

[0098] See also Figure 2 When the partition 21 is in the storage position, it only needs to avoid obstructing the airflow flowing into the wind space 10d as much as possible. In other words, the partition 21 only needs to avoid the wind space 10d as much as possible. Compared with the partition 21, the installation space 10g is actually a relatively large area. Therefore, an installation groove 10g1 is provided at the junction of the wind space 10d and the installation space 10g, which is convenient for storing the partition 21 and can minimize the travel of the partition 21 in the installation space 10g.

[0099] In addition, by separating the installation groove 10g1 in the installation space 10g, it is also possible to prevent the airflow from flowing into a narrow area in the installation space 10g to cause turbulence and air volume loss.

[0100] In one embodiment, please refer to Figure 3 and Figure 4 The separation position may include a first separation position and a second separation position. The horizontal plane P when the air conditioner indoor unit is in the installation state is used as the reference plane. The installation state refers to the state when the air conditioner indoor unit is installed indoors during the use phase. The horizontal plane P is a virtual reference plane defined for the convenience of description. Figure 3 When the partition 21 is in the first partition position, the angle between the surface of the partition 21 facing the first air passage 10d1 and the reference surface is the first angle θ1, see Figure 4 When the partition 21 is in the second separation position, the angle between the surface of the partition 21 facing the first air passage 10d1 and the reference plane is a second angle θ2, and the first angle θ1 is greater than the second angle θ2.

[0101] Specifically, for ease of description, the opening of the first air passage 10d1 toward the air inlet 10a may be referred to as the first opening, and the opening of the second air passage 10d2 toward the air inlet 10a may be referred to as the second opening. Figure 3 When the partition plate 21 is in the middle position, the size of the first opening of the first air passage 10d1 is larger than that of the partition plate 21 in the second separation position (i.e. Figure 4 When the partition 21 is in the second partition position, the size of the second opening of the second air passage 10d2 is larger than the size of the second opening when the partition 21 is in the first partition position. That is to say, when the partition 21 is in the first partition position, the size of the opening of the first air passage 10d1 toward the air inlet 10a is relatively large. When the partition 21 is in the second partition position, the size of the opening of the second air passage 10d2 toward the air inlet 10a is relatively large. Therefore, in the single-side air outlet mode, the partition 21 can be controlled to be in the first partition position or the second partition position as needed.

[0102] For example, in the air conditioning control method, in the single-side air outlet mode, if the first fan is controlled to operate, the partition can at least be controlled to be in the first partition position. If the second fan is controlled to operate, the partition can at least be controlled to be in the second partition position.

[0103] That is to say, if air is discharged from the first air duct 10e, the partition 21 can be in the first partition position, and the opening size of the first air passage 10d1 toward the air inlet 10a is relatively large (that is, the size of the first opening at this time is relatively large), and more airflow enters the first air passage 10d1, thereby increasing the air volume.

[0104] Similarly, if the second air duct 10f is outlet, the partition 21 can be in the second partition position, and the opening size of the second air passage 10d2 toward the air inlet 10a is relatively large (that is, the size of the second opening at this time is relatively large), and more airflow enters the second air passage 10d2, thereby also playing a role in increasing the air volume.

[0105] It should be noted that in some embodiments, in the single-side air outlet mode, if the first fan is controlled to run, the partition can also be controlled to be in the second separation position. Similarly, if the second fan is controlled to run, the partition can also be controlled to be in the first separation position. In other words, whether the first fan is controlled to run or the second fan is controlled to run, the partition can be controlled to be in the first separation position or the second separation position according to the required air volume.

[0106] In addition, the size of the first angle θ1 can be set as needed. Preferably, the first angle θ1 can be greater than 90° and less than 150°, that is, 30°<θ1<90°. This angle can not only make the partition plate 21 play a better separation role, but also increase the size of the opening of the first air passage 10d1 toward the air inlet 10a as much as possible.

[0107] The size of the second angle θ2 can be set as needed. Preferably, the second angle θ2 can be greater than 30° and less than 90°, that is, 30° < θ2 < 90°. This angle can not only make the partition plate 21 play a better separation role, but also increase the size of the opening of the second air passage 10d2 toward the air inlet 10a as much as possible.

[0108] In one embodiment, please refer to Figure 5 The partition position may also include a third partition position. When the partition 21 is in the third partition position, the angle between the surface of the partition 21 facing the first air passage 10d1 and the reference plane is a third angle θ3, and the third angle θ3 is greater than the second angle θ2 and less than the first angle θ1.

[0109] Specifically, for the first air passage 10d1, the partition plate 21 is in the third separation position (i.e. Figure 5 For the second air passage 10d2, when the partition 21 is in the third partition position, the size of the second opening of the second air passage 10d2 is smaller than the size of the second opening when the partition 21 is in the second partition position, but larger than the size of the second opening when the partition 21 is in the first partition position. That is, compared with the first and second partition positions, when the partition 21 is in the third partition position, the difference between the size of the first opening and the size of the second opening is relatively small.

[0110] For example, see Figure 5 , the third angle θ3 can be equal to 90°, that is, when the partition 21 is in the third separation position, the size of the first opening is approximately the same as the size of the second opening, which is equivalent to the air volume entering the first air passage 10d1 from the first opening being approximately the same as the air volume entering the second air passage 10d2 from the second opening.

[0111] In some embodiments, the third angle θ3 may not be equal to 90°, that is, as long as the third angle θ3 is greater than the second angle θ2 and less than the first angle θ1.

[0112] See also Fig. 9, taking the partition plate being able to rotate to the first separation position, the second separation position and the third separation position as an example, if the air outlet mode is a single-side air outlet mode, the method may include the following steps:

[0113] Step S1031: controlling the partition to be in the third partition position, and controlling the first fan or the second fan to operate according to a set control strategy;

[0114] Step S1032: Determine to open the high wind shield. If the first fan is running, control the partition to rotate from the third separation position to the first separation position; if the second fan is running, control the partition to rotate from the third separation position to the second separation position.

[0115] Specifically, when the partition is in the third separation position, it can be considered that the air conditioner indoor unit turns on the conventional windshield. In the single-side air outlet mode, whether it is controlling the operation of the first fan or the second fan, the partition can be in the third separation position first, that is, the conventional windshield is turned on by default. If a control signal to turn on the high windshield is received, and the first fan is currently turned on, the partition is controlled to rotate from the third separation position to the first separation position. If a control signal to turn on the high windshield is received, and the second fan is currently turned on, the partition is controlled to rotate from the third separation position to the second separation position, which is equivalent to switching from the conventional windshield to the high windshield if the high windshield needs to be turned on.

[0116] In some embodiments, the partition 21 may be provided with only the first partition position and the second partition position without providing the third partition position, or may be provided with only the third partition position without providing the first partition position and the second partition position.

[0117] Also, see Figure 1 For an indoor air conditioner in which the partition plate 21 is rotatably disposed in the housing 10 and the heat exchange body 71 of the heat exchanger 70 is disposed between the air inlet 10a and the air flow space 10d, the setting position of the rotation axis C3 of the partition plate 21 also needs to avoid the delivery pipe of the heat exchanger 70. For example, refer to Figure 1 Taking the air conditioner indoor unit in the installation state as an example, the air conditioner indoor unit has a first vertical plane C1 coincident with the rotation axis of the first fan 30, a second vertical plane C2 coincident with the rotation axis of the second fan 40, and a central vertical plane C0 located between the first vertical plane C1 and the second vertical plane C2. The first vertical plane C1, the second vertical plane C2 and the central vertical plane C0 are all virtual reference planes defined for the convenience of description. The first vertical plane C1, the second vertical plane C2 and the central vertical plane C0 are all aligned with the horizontal plane P (reference plane Figure 3), the distance between the first vertical plane C1 and the central vertical plane C0 is equal to the distance between the second vertical plane C2 and the central vertical plane C0, which is equivalent to the first vertical plane C1 and the second vertical plane C2 being symmetrically arranged relative to the central vertical plane C0. The rotation axis C3 of the partition 21 and the conveying pipe (not shown) can be located on opposite sides of the central vertical plane C0 respectively. Figure 1 In the embodiment, if the rotation axis C3 of the partition 21 is located on the side of the central vertical plane C0 close to the second vertical plane C2, the delivery pipe can be arranged on the side of the central vertical plane C0 close to the first vertical plane C1. In another embodiment, if the rotation axis C3 of the partition 21 is located on the side of the central vertical plane C0 close to the first vertical plane C1, the delivery pipe can be arranged on the side of the central vertical plane C0 close to the second vertical plane C2.

[0118] The distance between the rotation axis C3 of the partition 21 and the central vertical plane C0 can be determined according to the setting position of the conveying pipe and the length of the conveying pipe. For example, the distance between the rotation axis C3 and the central vertical plane C0 can be about 10 mm.

[0119] It should be noted that the delivery pipe may also be arranged at other positions, and on the premise that the arrangement position of the delivery pipe does not interfere with the rotation of the partition 21 , the rotation axis C3 of the partition 21 may also coincide with the central vertical plane C0 .

[0120] For the translational partition 21, in one embodiment, please refer to Figure 6 and Figure 7 The partition 21 may be arranged in a translationally movable manner in the installation space 10g, see Figure 6 When the partition 21 is in the storage position, the partition 21 is located in the installation space 10g, that is, the partition 21 can be stored in the installation space 10g to minimize the partition 21 from obstructing the airflow flowing into the wind space 10d in the normal air outlet mode.

[0121] Please continue reading Figure 7 Under the drive of the driving mechanism 22, the partition 21 moves into the wind passage space 10d by translation, and the partition 21 switches to the separation position. That is, the partition 21 extends from the installation space 10g into the wind passage space 10d by translation, thereby dividing the wind passage space 10d into the first wind passage 10d1 and the second wind passage 10d2.

[0122] See also Figure 6 and Figure 7 For an indoor air conditioner in which the heat exchange body 71 of the heat exchanger 70 is disposed between the air inlet 10a and the air flow space 10d, the partition 21 should also avoid the delivery pipe of the heat exchanger 70. Therefore, the partition 21 and the delivery pipe can also be disposed at Figure 1 Opposite sides of the central vertical plane C0 shown.

[0123] For further information, see Figure 6 and Figure 7 , the installation space 10g is connected to the wind passing space 10d through the connecting port 10g2, and the partition 21 enters the wind passing space 10d through the connecting port 10g2. When the partition 21 is in the storage position, the partition 21 can block the connecting port 10g2. That is, in the storage position, the airflow entering the wind passing space 10d will hardly flow into the installation space 10g from the connecting port 10g2, thereby reducing the air volume loss.

[0124] In addition, the driving mechanism 22 drives the partition plate 21 to move in a translational manner. For example, please refer to Figure 6 and Figure 7 The driving mechanism 22 may be provided with a driving motor (not shown) and a gear 221 and a rack 222 that mesh with each other. The gear 221 and the rack 222 are actually a transmission assembly. The rack 222 is provided on the partition 21. The driving motor drives the gear 221 to rotate, so that the rack 222 drives the partition 21 to move horizontally.
