Specifically, the number of the air ducts 11c may be two, or may be two or more.
The plurality of air ducts 11c which are independently arranged and can be communicated through the air passing openings 11b means that each air duct 11c can be independently used, and any two air ducts 11c can be communicated through the air passing openings 11b, wherein the number of the air passing openings 11b needs to be determined according to the number of the air ducts 11c and the relative position between the air ducts 11c, for example, please refer to fig. 2 and 3, the air-conditioning indoor unit 10 shown in fig. 2 and 3 has three air ducts 11c, and three air passing openings 11b are arranged on the partition wall 11a in order to realize the communication between the three air ducts 11 c. In another embodiment, when the air conditioning indoor unit 10 has only two air ducts 11c, the two air ducts 11c may be communicated with each other through one air inlet 11 b.
For example, referring to fig. 2 and 3, the partition 11a may partition the air passing cavity 11f and a plurality of air channels 11c surrounding the air passing cavity 11f in the housing 11, and each air channel 11c is communicated with the air passing cavity 11f through an air passing opening 11 b. That is, the air channels 11c can be communicated with each other through the air passing chamber 11f, and the air flow from one air channel 11c needs to pass through the air passing chamber 11f to flow into the next air channel 11 c. When the number of the air paths 11c is large, providing the air passing chamber 11f may facilitate the arrangement of the positions of the respective air paths 11 c.
In some embodiments, the air inlets 11b may be disposed on the partition wall 11a between two adjacent air ducts 11c to communicate the two adjacent air ducts 11 c.
The number of the air valves 13 of the air ducts 11c needs to be determined according to the number of the air inlets 11b, that is, at least one air valve 13 is required at each air inlet 11b, and the air valve 13 can selectively open or close the corresponding air inlet 11b through opening and closing, so that communication or closing between the corresponding air ducts 11c can be realized.
The forward/reverse rotation fan 122 is a fan that can rotate forward or reverse, and the fan can change the flow direction of the air flow by rotating forward or reverse.
The type of the counter-rotating fan 122 is not limited, and the counter-rotating fan 122 may be an axial flow fan, for example.
The number of the forward/reverse fans 122 in the same air duct 11c may be determined as required, that is, the number of the forward/reverse fans 122 in the same air duct 11c may be one or multiple, for example, referring to fig. 2 and 3, two forward/reverse fans 122 are disposed in one air duct 11c of the air-conditioning indoor unit 10 shown in fig. 2 and 3, and one forward/reverse fan 122 is disposed in the other air duct 11 c.
Referring to fig. 1 to 3, the fact that each air duct 11c is in one-to-one communication with at least one part of the rooms through the air return opening 11d and the air outlet 11e means that the number of the air ducts 11c of the indoor unit 10 of the air conditioner may be less than the number of the rooms in the house 20, however, the number of the air ducts 11c should be the same as the number of the rooms in which the air conditioner provided in the embodiment of the present application needs to be used, and the air return opening 11d and the air outlet 11e of each air duct 11c are respectively disposed in different rooms. For example, five rooms are provided in the house 20 shown in fig. 1, but only three rooms (i.e., the room a 20a, the room B20B, and the room C20C shown in fig. 1) need to use the air conditioner provided in the embodiment of the present application, and therefore, an indoor air conditioner 10 having three ducts 11C (for convenience of description, the three ducts 11C corresponding to the room a 20a, the room B20B, and the room C20C are referred to as an air duct a 11ca, an air duct B11 cb, and an air duct C11 cc respectively) is provided in the house 20 shown in fig. 1, the return air opening 11d and the air outlet 11e of the air duct a 11ca are provided in the room a, the return air opening 11d and the air outlet 11e of the air duct B11 cb are provided in the room B, and the return air opening 11d and the air outlet 11e of the air duct C11 cc are provided in the room C20C.
In addition, the indoor air conditioner 10 may further include an openable return air grille, the return air inlets 11d of the air ducts 11c may be provided with return air grilles, and the opening or closing of the corresponding return air inlets 11d may be achieved by controlling the opening or closing of the return air grilles.
Similarly, the air conditioning indoor unit 10 may also be provided with an openable outlet grille, the outlet 11e of each air duct 11c may be provided with an outlet grille, and the opening or closing of the outlet grille may be controlled to open or close the corresponding outlet 11 e. It can be understood that, when the air conditioner is in an operating state, the air outlet grille at the air outlet 11e of the corresponding air duct 11c should be in an open state.
Another embodiment of the present application further provides a control method for an air conditioner, where the control method is used in the air conditioner described in any embodiment of the present application, the air conditioner has an interconnection mode, in the interconnection mode, at least one of the plurality of air ducts is an air guide duct, and at least one of the plurality of air ducts is a target air duct, please refer to fig. 4, and the control method includes the following steps:
step S101: and under the interconnection mode, opening an air valve for communicating the air guide air duct with the target air duct, controlling a forward and reverse rotating fan in the air guide air duct to rotate reversely, and controlling the forward and reverse rotating fan in the target air duct to rotate forwardly so as to introduce the air flow in the room communicated with the air guide air duct into the room communicated with the target air duct.
Specifically, the air guide duct refers to a duct that is required to guide an air flow in a room communicated with the air guide duct into another room among the plurality of ducts, and the target duct refers to a duct that receives the air flow from the air guide duct. It will be appreciated that the guide duct and the target duct are not fixed and may vary depending on the room in which the airflow is provided and the room in which the airflow is received, i.e. any one duct may become the guide duct or the target duct. In addition, in the interconnected mode, any air duct which is not communicated with other air ducts is not an air guide air duct or a target air duct.
Taking the air-conditioning indoor unit 10 shown in fig. 1 to 3 as an example, when the airflow in the room a 20a needs to be introduced into the room B20B, the air duct a 11ca is the air guide duct 11C, and the air duct B11 cb is the target duct 11C, and when the airflow in the room B20B needs to be introduced into the room a 20a, the air duct B11 cb is the air guide duct 11C, and the air duct a 11ca is the target duct 11C, in the above two scenarios, the air duct C11 cc is neither the air guide duct 11C nor the target duct 11C, but in some scenarios, when the airflow in the room C20C needs to be introduced into other rooms, the air duct C11 cc becomes the air guide duct 11C, and when the airflow in other rooms needs to be introduced into the room C20C, the air duct C11 cc becomes the target duct 11C.
In addition, in the same scene, there may be a plurality of air guide ducts and a plurality of target ducts, for example, also taking the air conditioner indoor unit 10 shown in fig. 1 to 3 as an example, in one scene, both the a duct 11ca and the B duct 11cb may be the air guide duct 11C, the C duct 11cc may be the target duct 11C, and in another scene, the a duct 11ca may be the air guide duct 11C, and the B duct 11cb and the C duct 11cc may be the target duct 11C.
