In this embodiment, the airflow enters the first air duct 114 from the first air inlet 112, enters the second air duct 115 from the second air inlet 113, exchanges heat with the first heat exchanger 30 and the second heat exchanger 50 respectively, and then is blown out from the air outlet 111. The first air duct 114 and the second air duct 115 may be connected to each other or may be independent of each other, and are not limited herein, and only need to be connected to the air outlet 111. The first heat exchanger 30 may be disposed between the first air inlet 112 and the wind wheel, or between the air outlet 111 and the wind wheel, which is not limited herein, and only needs to satisfy that the airflow will flow through the first heat exchanger 30 before flowing through the air outlet 111; the second heat exchanger 50 works in the same way. It should be noted that the first heat exchanger 30 and the second heat exchanger 50 are both indoor heat exchangers, that is, the first heat exchanger 30 and the second heat exchanger 50 cool or heat simultaneously. The air is supplied to the air outlet 111 through the double air ducts, so that the air output and the air supply distance of the air outlet 111 can be increased, and the air supply requirement of a user can be met.

The window air conditioner of the utility model realizes double-air-channel air inlet and heat exchange by arranging two air inlets and two air channels at the indoor side 11 and arranging wind wheels and heat exchangers in the two air channels; the two air channels can discharge air through the same air outlet 111, so that the discharged air flow can be more concentrated, and the air output and air supply distance of the air outlet 111 can be increased.

It should be noted that, if directional indications (such as upper, lower, left, right, front and rear … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are changed accordingly.

In addition, if there is a description relating to "first", "second", etc. in the embodiments of the present invention, the description of "first", "second", etc. is for descriptive purposes only and is not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.

The window air conditioner further comprises a rear partition plate for separating the indoor side 11 from the outdoor side 12, and the guide plate and the middle partition plate 61 can be connected with the rear partition plate or integrally formed, so that the structural strength and the assembly stability of the guide plate and the middle partition plate 61 are improved.

In an embodiment, as shown in fig. 2, the air duct component further includes a first volute tongue portion 64 abutting against the front end of the first wind wheel 20, and a second volute tongue portion 65 abutting against the front end of the second wind wheel 40; the first volute tongue portion 64, the first baffle plate 62 and the middle partition plate 61 enclose to form the first air duct 114, and the second volute tongue portion 65, the second baffle plate 63 and the middle partition plate 61 enclose to form the second air duct 115. In this embodiment, the baffle plate is connected with the middle partition plate 61 to form the volute, the volute tongue portion and the volute enclose to form the air duct, the front end of the wind wheel abuts against the volute tongue portion, and the rear end of the wind wheel abuts against the inner wall surface of the volute, so that the gap between the wind wheel and the volute tongue portion can be reduced, and the air flow can be ensured to flow to the air outlet 111 completely.

second volute sections

64 and 65 are respectively connected to the rear edges of the two vertical frame strips of the frame body 71. In this embodiment, the volute tongue portion has a forward-extending abutting plate, and the front side of the abutting plate is connected to the mullion strip of the frame 71, so as to realize the sealing transition between the air duct and the air outlet 111, so that the air flow of the first air duct 114 can all flow to the air outlet 111, thereby improving the air outlet efficiency.

In practical applications, as shown in fig. 2, two vertical frame bars of the frame 71 surround to form a forward flaring shape. In this embodiment, the two mullions strips have a certain width in the front-back direction and extend obliquely in the direction away from each other to form a flaring shape facing forward. Because the air outlet surface of each air duct corresponding to the air outlet 111 is actually positioned between the vertical frame strip of the air outlet frame and the middle partition plate 61, the air outlet is concentrated; the two vertical frame strips of the air-out frame form an opening-expanding shape, so that the air-out angle can be expanded, and the air-out area is increased. In addition, the two transverse strips of the frame strip can also be enclosed to form a flaring shape so as to further improve and enlarge the air supply area.
