In the technical scheme, when the ambient temperature is greater than or equal to the first temperature threshold, the ambient temperature is high, a user may feel hot, the operation mode matched with the indoor unit of the air conditioner may be any one or a combination of a cooling mode, a dehumidification mode and an air supply mode, when the ambient temperature is less than the first temperature threshold, the indoor temperature is low, the user may feel cold, the determination unit 206 determines that the operation mode matched with the indoor unit of the air conditioner is the heating mode, the matched operation mode of the indoor unit is determined by detecting the ambient temperature, when the user selects the operation mode which is suitable for operation but conflicts with the current mode, the indoor unit does not send a conflict prompt, the operation mode is directly switched, the number of times of mode conflicts for reminding the user is reduced, and the use experience of the user is improved.

In an embodiment of the present invention, as shown in fig. 6, preferably, the determining unit 206 is further configured to, based on the situation that the ambient temperature is greater than or equal to the first temperature threshold and less than the second temperature threshold, and the ambient humidity is greater than the first humidity threshold, match the operation modes as follows: an air supply mode and a dehumidification mode.

In this embodiment, when the ambient temperature is greater than or equal to the first temperature threshold and less than the second temperature threshold, and the ambient humidity is greater than the first humidity threshold, the ambient temperature is not high, and cooling is not necessary, but the humidity is high, and the user has a certain stuffiness feeling, so dehumidification is necessary, at this time, the determining unit 206 determines that the matched operation mode of the indoor unit of the air conditioner is the air supply mode and the dehumidification mode, and the user can flexibly select according to the situation of the user, and the indoor unit does not prompt a conflict.

In an embodiment of the present invention, as shown in fig. 6, preferably, the determining unit 206 is further configured to, based on the situation that the ambient temperature is greater than or equal to the second temperature threshold and the ambient humidity is greater than the second humidity threshold, match the operation modes as follows: a cooling mode and a dehumidification mode.

In this embodiment, when the ambient temperature is greater than or equal to the second temperature threshold and the ambient humidity is greater than the second humidity threshold, the ambient temperature is higher and needs to be cooled, and meanwhile, because the humidity is higher, the user feels sultry and needs to dehumidify, at this time, the determining unit 206 determines that the matched operation mode of the indoor unit of the air conditioner is the cooling mode and the dehumidification mode, the user can flexibly select according to the self condition, and the indoor unit does not prompt a conflict.

In an embodiment of the present invention, as shown in fig. 6, preferably, the determining unit 206 is further configured to, based on the situation that the ambient temperature is greater than or equal to the second temperature threshold and the ambient humidity is less than the second humidity threshold, match the operation modes as follows: a cooling mode.

In this embodiment, when the ambient temperature is greater than or equal to the second temperature threshold and the ambient humidity is less than the second humidity threshold, the ambient temperature is high, and cooling is required, and meanwhile, because the humidity is not high, the user only feels heat, and therefore dehumidification is not required, at this time, the determining unit 206 determines that the matched operation mode of the indoor unit of the air conditioner is the cooling mode, and the user can flexibly select according to the self condition, and the indoor unit does not prompt a conflict.

In one embodiment of the present invention, preferably, when the ambient temperature is greater than or equal to 26 ℃ and the humidity is less than 60%, the user feels hot but not stuffy (the humidity is low and sweat can evaporate), the currently suitable operation mode of the air conditioner is determined as the cooling mode, when the ambient temperature is greater than or equal to 26 ℃ and the humidity is greater than or equal to 60%, the user feels stuffy (the temperature is high and the humidity is high and the sweat is not evaporated), the currently suitable operation mode of the air conditioner is determined as the dehumidification mode and the cooling mode, when the ambient temperature is greater than or equal to 18 ℃ and less than 26 ℃ and the humidity is greater than 70%, the user feels stuffy (the humidity is high and the sweat is not evaporated), the currently suitable operation mode of the air conditioner is determined as the dehumidification mode and the air supply mode, when the ambient temperature is less than or equal to 18 ℃, the user feels cold, and the.
