The housing 110 is provided with an air inlet 111 communicating with the air processing chambers 112, it is understood that the air inlet 111 communicates with each of the air processing chambers 112, and air can enter each of the air processing chambers 112 from the air inlet 111. Specifically, the air inlet 111 is disposed on a peripheral side wall of the housing 110, and the number of the air inlets 111 may be one, two or more. In addition, the shape of the air inlet 111 may be various, for example, it may be a circle, an ellipse, a square, a triangle, or other irregular shapes, and the like, which is not limited in particular. The shape of the air outlet 115 may be various, for example, it may be a circle, an ellipse, a square, a triangle, or other irregular shapes, and the like, which is not limited in particular. Without loss of generality, an air inlet grille can be arranged at the air inlet 111, and an air outlet grille is arranged at the air outlet 115.

The air-conditioning indoor unit 300 comprises a main unit 200 and a sub unit 100 detachably mounted on the main unit 200, wherein the sub unit 100 comprises a shell 110, a switching component 130 and an air processing module 140, the shell 110 is provided with a sub unit air duct, the sub unit air duct comprises at least two air processing cavities 112 and a fan cavity 115, and the shell 110 is provided with an air inlet 111 communicated with the air processing cavities 112 and an air outlet 116 communicated with the fan cavity 115; the switching component 130 is used for communicating or blocking the air duct of the submachine so as to communicate the at least one air processing cavity 112 with the fan cavity 115; each of the air treatment modules 140 is disposed within a corresponding one of the air treatment chambers 115; thus, when the switching component 130 connects one of the air processing chambers 112 with the blower chamber 115, air enters the air processing chamber 112 from the air inlet 111, passes through the blower chamber 115 after being processed by the air processing module 140 in the air processing chamber 112, and is finally blown out from the air outlet 116, so that the processing of a single function of air can be realized; when the switching assembly 130 connects the air treatment chambers 112 to the blower chamber 115, air enters the air treatment chambers 112 from the air inlet, passes through the air treatment modules 140 in the air treatment chambers 112, flows through the blower chamber 115, and is blown out from the air outlet 116, so that the air can be treated in multiple functions. Therefore, the sub-unit 100 of the air conditioning indoor unit 300 of the present invention can provide a plurality of air treatment modes, thereby well satisfying diverse air treatment demands of users.

Two air treatment chambers 112 will be described in detail below as an example. For ease of description, the at least two air treatment chambers 112 include a first air treatment chamber 113 and a second air treatment chamber 114. There are various arrangements of the first air processing chamber 113, the second air processing chamber 114 and the fan chamber 115, for example, referring to fig. 5, in some embodiments, the first air processing chamber 113, the second air processing chamber 114 and the fan chamber 115 may be arranged in an up-and-down direction.

Referring to fig. 9 and 10, in the present embodiment, the switching assembly 130 is located between the first air processing chamber 113 and the second air processing chamber 114, so as to connect the first air processing chamber 113 and/or the second air processing chamber 114 with the fan chamber 115. Wherein the first air treatment chamber 113 may be located below the second air treatment chamber 114, and the blower chamber 115 is located above the second air treatment chamber 114. The switching assembly 130 has a conducting position and a blocking position, when the switching assembly 130 is in the conducting position (as shown in fig. 9), a portion of air enters the first air processing chamber 113 from the air inlet 111, flows into the fan chamber 115 through the second air processing chamber 114 after being processed by the air processing module 140 in the first air processing chamber 113, another portion of air enters the second air processing chamber 114 from the air inlet 111, flows into the fan chamber 115 after being processed by the air processing module 140 in the second air processing chamber 114, and finally both portions of air can be blown out from the air outlet 116. When the switching assembly 130 is in the blocking position (as shown in fig. 10), air enters the second air processing chamber 114 only from the air inlet 111, flows into the fan chamber 115 after being processed by the air processing module 140 in the second air processing chamber 114, and finally is blown out from the air outlet 116.

It is understood that the first air treatment chamber 113 may also be located above the second air treatment chamber 114, and the blower chamber 115 may be located above the first air treatment chamber 113. When the switching assembly 130 is in the on position, a portion of the air enters the second air processing chamber 114 from the air inlet 111, flows into the fan chamber 115 through the first air processing chamber 113 after being processed by the air processing module 140 in the second air processing chamber 114, enters the first air processing chamber 113 from the air inlet 111, flows into the fan chamber 115 after being processed by the air processing module 140 in the first air processing chamber 113, and finally both portions of the air can be blown out from the air outlet 116. When the switching assembly 130 is in the blocking position, air enters the first air processing chamber 113 only from the air inlet 111, flows into the fan chamber 115 after being processed by the air processing module 140 in the first air processing chamber 113, and finally is blown out from the air outlet 116.

In this embodiment, the inlet 111 includes a first inlet 111a communicating with the first air processing chamber 113, and a second inlet 111b communicating with the second air processing chamber 114. The first air inlet 111a is provided on a peripheral side wall of the housing 110, and the number of the first air inlets 111a may be one, two or more. The second air inlets 111b are also disposed on the peripheral side wall of the housing 110, and the number of the second air inlets 111b may also be one, two or more. In addition, the shapes of the first air inlet 111a and the second air inlet 111b may be various, for example, they may be circular, oval, square, triangular or other irregular shapes, and the like, which is not limited in detail.

For ease of description, the air treatment module 140 located in the first air treatment chamber 113 may be defined as a first air treatment module and the air treatment module 140 located in the second air treatment chamber 114 may be defined as a second air treatment module. In an embodiment, the first air treatment module mainly serves to humidify air, and may particularly be a humidifying module, such as a wet membrane. The sub-machine 100 further comprises a water tank for supplying water to the first air treatment module. Optionally, the first air treatment module is annularly disposed, and the first air treatment module is disposed corresponding to the first air inlet 111a, so that the humidification area and the humidification efficiency can be increased. The second air treatment module mainly plays a role of purifying air, and the second air treatment module can be specifically a purification module. Optionally, the second air treatment module may be annularly disposed, and the second air treatment module is disposed corresponding to the second air inlet 111b, so that on one hand, a purification area may be increased, and purification efficiency may be improved, and on the other hand, resistance to air may be reduced, and air volume loss may be reduced.

In this embodiment, when the switching assembly 130 is in the on position (as shown in fig. 9), the air entering from the first air inlet 111a is humidified by the first air processing module, then flows through the second air processing chamber 114 and is purified by the second air processing module, and finally flows through the fan chamber 115 and is blown out through the air outlet 116, so that the air purification and humidification mode can be realized; when the switching assembly 130 is in the blocking position (as shown in fig. 10), the air entering the first air processing chamber 113 from the first air inlet 111a cannot flow into the second air processing chamber 114, and at this time, the air flowing into the second air processing chamber 114 from the second air inlet 111b flows to the blower chamber 115 after being purified by the second air processing module, and finally is blown out through the air outlet 116, so that the air-only purification mode can be realized.

It should be noted that, in the purification and humidification mode, as shown in fig. 9, a portion of air enters the first air processing chamber 113 from the first air inlet 111a, is humidified by the first air processing module 140, flows into the second air processing chamber 114 and is purified by the second air processing module 150, and meanwhile, a portion of air enters the second air processing chamber 114 from the second air inlet 111b and is directly purified by the second air processing module 150, and then the air and the air are mixed and blown out from the air outlet 116 through the fan chamber 115. So can guarantee that the humidity of room air is suitable, also can reduce the wind loss simultaneously, and then increase the air output to improve the purification humidification effect to room air.

In this embodiment, the first air processing chamber 113 is located below the second air processing chamber 114, that is, the humidifying module is located below the purifying module, which is beneficial to improving the overall stability of the submachine 100. Since the humidifying module is generally heavy, the humidifying module is attached to the bottom of the slave unit 100, so that the overall stability of the slave unit 100 can be improved and the slave unit 100 is less likely to fall over. In addition, in this embodiment, a water tank is disposed at the bottom of the first air processing chamber 113, the humidifying module is disposed in the water tank, and the water tank is used for supplying water to the water tank.

In addition, there may be various structures regarding the switching assembly 130. For example, referring to fig. 8, in an embodiment, the switching assembly 130 includes a fixed plate 131 and a movable plate 132, the fixed plate 131 is connected to the housing 110, and the movable plate 132 is slidably connected to the fixed plate 131, so that the first air processing chamber 113 and/or the second air processing chamber 114 is communicated with the blower chamber 115. Specifically, one end of the fixed plate 131 is connected to the housing 110, and the other end is slidably connected to the movable plate 132. Thus, by sliding the sliding plate, communication or blocking of the first air treatment chamber 113 from the second air treatment chamber 114 can be achieved, thereby allowing communication between the first air treatment chamber 113 and/or the second air treatment chamber 114 and the blower chamber 115.

In another embodiment, the switching assembly 130 includes a partition that is rotatably coupled to the housing 110 to place the first air treatment chamber 113 and/or the second air treatment chamber 114 in communication with the blower chamber 115. Specifically, the partition may be turned upside down to communicate or block the first air processing chamber 113 with the second air processing chamber 114, so that the first air processing chamber 113 and/or the second air processing chamber 114 communicates with the blower chamber 115. In order to reduce the space required for the partition to rotate, the partition may include a first sub-board and a second sub-board, and the first sub-board and the second sub-board are respectively rotatably connected to two opposite sidewalls of the housing 110.

Referring to fig. 11, in other embodiments, the first air processing chamber 113 and the second air processing chamber 114 may also be arranged along a horizontal direction, and the blower chamber 115 is located above or below the first air processing chamber 113 and the second air processing chamber 114.

In this embodiment, the switching member 130 is rotatably connected to the housing 110, and the switching member 130 has a first communication position, a second communication position and a third communication position. Wherein the switching assembly 130 communicates the first air handling chamber 113 with the blower chamber and communicates the second air handling chamber 114 with the blower chamber 115 when the switching assembly 130 is in the first communication position (as shown in fig. 11). That is, the switching assembly 130 is located between the first air processing chamber 113 and the second air processing chamber 114.

When the switch assembly 130 is in the second communication position, the switch assembly 130 communicates the first air handling chamber 113 with the blower chamber 115 and blocks the second air handling chamber 113 from the blower chamber 115.
