As shown in fig. 1 to 8, the present embodiment provides an air conditioner indoor unit 10, and the air conditioner indoor unit 10 includes a fresh air device 100. The fresh air device 100 includes an air duct 110, a damper assembly, a water wash assembly, and a filter assembly 140. The air duct 110 is provided with a first air inlet 112 and a second air inlet 113 along the circumferential direction of the side wall of the air duct 110. The damper assembly is used to control the opening and closing of the first air inlet 112 and the second air inlet 113. The water washing assembly is used for washing the air entering the air duct 110 from the first air inlet 112. The filter assembly 140 is used for filtering the air entering the air duct 110 from the second air inlet 113.
In the present embodiment, as a specific example, as shown in fig. 7 and 8, the air conditioner indoor unit 10 is a floor air conditioner indoor unit 10.
In the present embodiment, the shape of the air duct 110 is not particularly limited. For example, the air chute 110 may be cylindrical, square-cylindrical, or other irregular shape. In the present embodiment, the inner sidewall of the air duct 110 refers to other inner sidewalls of the air duct 110 except for the upper wall and the lower wall. Taking the shape of the air duct 110 as a rectangular parallelepiped as an example, the inner side walls of the air duct 110 refer to the left inner wall, the right inner wall, the front inner wall, the rear inner wall, and the like of the air duct 110.
Air duct 110 in this embodiment, the air flowing in the air duct 110 may be only indoor air, outdoor air, or mixed air of the indoor air and the outdoor air.
In this embodiment, the flowing direction of the air in the air duct 110 is not limited, and can be selected according to the requirement. As a specific example, as shown in fig. 2, 4 and 6, the gas flows upward within the air chute 110. Here, the upward direction should be construed broadly. Upward may be vertically upward, obliquely upward, first upward then leftward, first upward then rightward, first upward then forward, or first upward then rearward, etc. As a specific example, as shown in fig. 2, 4 and 6, the arrow line indicates the flow direction of the gas. The gas flows upward within the air duct 110.
The air duct 110 is provided with a first air inlet 112 and a second air inlet 113 along the circumferential direction of the side wall of the air duct 110, that is, the first air inlet 112 and the second air inlet 113 are arranged along the circumferential direction of the side wall of the air duct 110. In this embodiment, the first air inlet 112 and the second air inlet 113 may be closed or non-closed along the circumferential direction of the side wall of the air duct 110. As a specific example, as shown in fig. 1 to 6, the first air inlet 112 and the second air inlet 113 are closed along the circumferential direction of the side wall of the air duct 110 so that the first air inlet 112 and the second air inlet 113 are annular in shape. Here, the ring shape is to be broadly understood and may be a circular ring shape, a square ring shape, or other irregular shape. The specific shape of the ring is related to the shape of the air duct 110, the path for opening the first and second air ports, and the like.
In this embodiment, the specific structures of the first air inlet 112 and the second air inlet 113 are not limited. Taking the first air duct 110 and the second air duct 110 not closed as an example, the first air inlet 112 and the second air inlet 113 may be long-strip-shaped through holes, or consist of a plurality of through holes arranged at intervals on the air duct 110. Taking the first air inlet 112 and the second air inlet 113 as an example, which are closed along the circumferential direction of the side wall of the air duct 110, the first air inlet 112 and the second air inlet are formed by a plurality of through holes arranged at intervals on the side wall of the air duct 110 to ensure the continuity of the air duct 110.
In this embodiment, the type, number, etc. of the dampers included in the damper assembly are not limited and may be selected as desired. For example, the damper assembly may include only one damper or two dampers, one damper controlling the opening and closing of the first and second intake ports 112 and 113, or two dampers controlling the opening and closing of the first and second intake ports 112 and 113, respectively.
In this embodiment, the specific opening and closing states of the first air inlet 112 and the second air inlet 113 are not limited, and can be selected according to the requirement. As a specific example, as shown in fig. 1 and 2, when the gas requires both water washing and filtering, the first and second intake ports 112 and 113 are simultaneously opened.
As shown in fig. 3 and 4, when the gas only needs to be filtered, the first intake vent 112 is in a closed state, and the second intake vent 113 is in an open state. As shown in fig. 5 and 6, when the gas only needs to be washed with water, the first intake port 112 is in an open state, and the second intake port 113 is in a closed state.
In this embodiment, the type of the water washing assembly is not limited, and it may be enough to wash the air entering the air duct 110 from the first air inlet 112. The type of the filter assembly 140 is not limited, and it may filter the air entering the air duct 110 from the second air inlet 113.
The first air inlet 112 and the second air inlet 113 are arranged along the circumferential direction of the side wall of the air duct 110, so that the air inlet volume of the air duct 110 is relatively large and the air inlet is relatively uniform. The opening and closing of the first air inlet 112 and the second air inlet 113 are switched so that the air output by the fresh air device 100 includes water-washed air, filtered air or water-washed and filtered air. This makes the new trend device 100 simple structure, and the function is various.
In other embodiments, the first air inlet 112 and the second air inlet 113 are both closed along the circumferential direction of the side wall of the air duct 110 so as to respectively surround the air duct 110. This makes the intake of the air duct 110 relatively uniform and relatively large.
In other embodiments, the air duct 110 is configured to be continuous at the first air inlet 112 and the second air inlet 113. In this embodiment, the specific manner of the air duct 110 being continuous at the first air inlet 112 and the second air inlet 113 is not limited, and can be selected according to the requirement. For example, the air duct 110 may be connected to the first air inlet 112 and the second air inlet 113 such that the air duct 110 is continuous. As a specific embodiment, the first air inlet 112 and the second air inlet 113 are formed by a plurality of through holes spaced apart from each other on a side wall of the air duct 110, so that the air duct 110 is continuous at the first air inlet 112 and the second air inlet 113.
In other embodiments, the first air inlet 112 and the second air inlet are formed by a plurality of through holes spaced apart from each other on the side wall of the air duct 110, so that the air duct 110 is continuous at the first air inlet 112 and the second air inlet 113. The continuity of the air duct 110 can be ensured without adding other structures, so that the fresh air device 100 has a simple structure and is elegant in appearance.
In other embodiments, the damper assembly includes a tubular damper 120, and the tubular damper 120 moves along the length direction of the air duct 110 to open and close the first and second air inlets 112 and 113.
In the present embodiment, the length direction of the air duct 110 refers to the flow direction of the air in the air duct 110. As a specific example, as shown in fig. 1 to 6, the gas flows upward in the wind tunnel 110, and thus, the length direction of the wind tunnel 110 refers to a vertical direction. The movement of the tube damper 120 in the lengthwise direction of the air duct 110 means that the tube damper 120 moves in the vertical direction.
In this embodiment, the tube damper 120 is sleeved outside the air duct 110, or the air duct 110 is sleeved outside the tube damper 120. The shape of the cylindrical damper 120 is adapted to both the first intake port 112 and the second intake port 113 so that the first intake port 112 and the second intake port 113 can be opened and closed.
As shown in fig. 1 and 2, when the tubular damper 120 is removed from the first intake vent 112 and the second intake vent 113, both the first intake vent 112 and the second intake vent 113 are in an open state. As shown in fig. 3 and 4, when the cylindrical damper 120 is moved to the first intake port 112 and is moved away from the second intake port 113, the first intake port 112 is in a closed state, and the second intake port 113 is in an open state. As shown in fig. 5 and 6, the tubular damper 120 moves to the second intake port 113, and when the tubular damper moves away from the first intake port 112, the second intake port 113 is in a closed state, and the first intake port 112 is in an open state. This makes the new trend device 100 simple in structure, easy to control.
In other embodiments, the water wash assembly further comprises a water tank assembly and a humidifying shade 133. The water tank assembly and the side walls of the air duct 110 together define a water storage chamber 132 for storing water.
