In this embodiment, two air supply modes for the evaporator 202 are implemented by providing the first air supply sub-port 2042 and the second air supply sub-port 2044, generally, the second air duct 108 and the second air supply sub-port 2044 provide fresh clean air with high oxygen content for the evaporator 202 to improve the indoor air quality, the second air supply sub-port 2044 can be connected with the indoor space to serve as the air conditioning air supply port 204 for internal circulation, and the switching structure can also implement switching of the first air supply sub-port 2042 or the second air supply sub-port 2044 (in fig. 1, the second air supply sub-port 2044 is opened to close the first air supply sub-port 2042 to introduce fresh air into the indoor space, in fig. 2, the first air supply sub-port is opened to close the second air supply sub-port to cool or heat the air in the indoor space), thereby implementing a switching function of the air conditioner internal circulation mode or external circulation mode.
In one embodiment of the present invention, preferably, as shown in fig. 1 and fig. 2, further comprising: and an air inlet grill 206 disposed over the air inlet 204.
In this embodiment, the air inlet grille 206 is disposed on the air inlet 204, so that some large impurities can be filtered, the situation that the use of the evaporator 202 is affected or even the air conditioner equipment is damaged due to the impurities entering the evaporator 202 by mistake is avoided, and meanwhile, the air inlet direction can be controlled by setting the grille shape of the air inlet grille 206, so as to improve the air inlet efficiency and the heating or cooling efficiency of the air conditioner 20.
