The evaporator 900 is used for exchanging heat with air entering the housing 100 from the air inlet 110 to form heat-exchange air (specifically, cold air during cooling and hot air during heating). Evaporator 900 is preferably a three-section finned evaporator covering the space in front of and above crossflow blower 800.
The top of the housing 100 has an air inlet 110, and the air inlet 110 has an air inlet grille. The lower portion of the front side of the case 100 is provided with an upper outlet 120 and a lower outlet 130. The upper outlet 120 and the lower outlet 130 are arranged in the up-down direction. The upper outlet 120 is provided at an upper side and facing forward, and the lower outlet 130 is opened at a lower side and facing forward and downward. As shown in fig. 1, the housing 100 may be an elongated structure extending in the transverse direction (i.e., left-right direction). The upper outlet 120 and the lower outlet 130 are elongated openings extending in the transverse direction.
An air duct 300 is arranged in the casing 100, an inlet end of the air duct 300 is located at the fan, and an outlet end of the air duct 300 is located at the two air outlets. The air duct 300 is used to guide the heat-exchange air from the evaporator 900 to the air outlet, so that the air is blown out from the air outlet, thereby realizing cooling/heating of the indoor environment.
The front edge of the baffle 500 is pivotally mounted to the housing 100 between the upper outlet 120 and the lower outlet 130, with the pivot axis 510 positioned as shown in fig. 2. The pivot axis 510 extends in a transverse direction.

In some embodiments, the second flow guide plate 520 extends from the width-wise central region 521 of the baffle 500 such that the angle between the second flow guide plate 520 and the baffle 500 is greater, and the flow of wind in the vicinity of the baffle 500 is more gradual when the baffle is in the upwind position.
Specifically, the air duct 300 is composed of an upper volute 320 and a lower volute 310, the inner wall of the lower volute 310 is the lower wall of the air duct 300, and the inner wall of the upper volute 320 is the upper wall of the air duct 300. With the baffle 500 in the aforementioned up-blowing position, the rear end thereof may be made to abut against the front edge of the lower volute 310. The upper volute 320 has a volute tongue 321, and when the guide plate 500 is at the downward blowing position, the rear end of the guide plate abuts against the volute tongue 321, so that after the guide plate 500 and the lower volute 310 form a new air duct together, the upper wall of the new air duct forms a complete volute profile again, the wind direction meets the flow direction requirement of the cross flow fan 800, and the fan efficiency is improved.
In some embodiments, a motor is mounted at the pivot axis of the baffle 500 for driving the baffle 500 to pivot. The motor is preferably a stepping motor capable of rotating forward and backward.
In some embodiments, as shown in fig. 3 and 4, when the baffle 500 is in the aforementioned down-blowing position, the baffle 500 and the lower wall of the wind tunnel 300 are both extended to be gradually inclined downward from back to front, so that the wind is inclined downward from front to front. As shown in fig. 2, when the baffle 500 is in the above-mentioned upward blowing position, the baffle 500 and the upper wall of the air duct 300 are both inclined upward from the rear to the front, so that the wind direction is inclined upward from the front.
In some embodiments, as shown in fig. 1 to 4, a wind deflector 200 is disposed at the lower wind outlet 130. The air guiding plate 200 is configured to be rotatable around a transverse axis to adjust the upward and downward air outlet directions of the lower air outlet 130. In addition, when the flow guiding plate 500 is located at the above-mentioned upward blowing position, the air guiding plate 200 is located outside the flow guiding plate 500, so that when the lower air outlet 130 is not needed for air supply, the air guiding plate 200 seals the lower air outlet 130, as shown in fig. 1 and fig. 2, the bottom appearance of the indoor unit of the air conditioner is more beautiful.
In some embodiments, as shown in fig. 2 to 4, an air outlet grille is disposed at the upper air outlet 120. The upper air outlet 120 is more beautiful due to the arrangement of the air outlet grille. Meanwhile, the air outlet grille can be configured to enable the air to pass through and then be blown obliquely forwards and upwards, so that the air outlet grille has the function of guiding the wind direction.
The wall-mounted air conditioner indoor unit provided by the embodiment of the invention can realize multiple air supply modes:
(1) no blowing mode. As shown in fig. 2, the baffle 500 is in the up-blow position. At the moment, wind is blown out in an upward mode, the user cannot be blown out, the refrigerating/heating performance cannot be influenced, the air supply effect of people cannot be blown out, discomfort caused by direct blowing of the user is avoided, and the wind feeling experience of the user is improved. When the air conditioner is used for refrigerating or heating, the mode of blowing no people can be adopted.
(2) A powerful heating mode. As shown in fig. 3, the baffle 500 is in the down-blowing position, and the air deflector 200 directs the wind downward such that the wind blows straight downward. Because the density of the hot air is low and the hot air has an ascending trend, the hot air is blown downwards as much as possible, and the heating effect can be enhanced.
(3) A forced cooling mode. As shown in fig. 4, the air guide plate 500 is in the downward blowing position, and the air guide plate 200 guides the air forward, so that the air blows forward, and the cold air is blown upward as much as possible due to the sinking tendency of the cold air with high density, thereby enhancing the cooling effect.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
