For example, a part of the air duct wall 320 of the air outlet duct may be formed by a cover of the casing 300, and the air outlet through hole 322 may be opened on the cover forming the air duct wall 320. Fig. 3 is a partially enlarged view of a portion a in fig. 2. As shown in fig. 3, the plurality of air outlet holes 322 may be arranged in an array.
The inside of the casing 300 is further formed with a heat exchange air duct, which is communicated with the air outlet duct and is located at the upstream of the air outlet duct. And a heat exchanger and an air supply fan are arranged in the heat exchange air duct. Wherein the heat exchanger is configured to exchange heat with a gas stream flowing therethrough. The casing 300 is further provided with an air inlet, and the air supply fan is used for promoting air from the indoor environment to enter the heat exchange air duct from the air inlet, and flow through the air outlet duct and the air outlet 310 in sequence after flowing through the heat exchanger, so as to flow into the indoor environment. The air supply fan can be a cross-flow fan, and the heat exchanger can be a three-section type heat exchanger surrounding the upper part of the cross-flow fan.

Fig. 4 is a schematic side view of the air conditioner indoor unit 10 shown in fig. 1. In some optional embodiments, the air conditioner indoor unit 10 further includes a wind deflector 200 having a first wind guiding section 210 located outside the wind outlet hole 322 for guiding the airflow exiting the wind outlet hole 322 to flow in a predetermined direction.
It should be noted that the terms indicating directions or positional relationships, such as "outside", "inside", "front", "back", "up", "down", etc., are based on the directions or positional relationships of the indoor unit 10 in the use state, which are only for convenience of description, and do not indicate or imply that the described devices or elements must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
For example, the air outlet 310 may be located at the bottom side of the front of the cabinet 300, and the air outlet hole 322 may be located at the bottom of the cabinet 300 and disposed adjacent to the air outlet 310. The outer side of the air outlet hole 322 may be the lower side thereof. The first air guiding section 210 is located below the air outlet hole 322, and is configured to guide the airflow exiting the air outlet hole 322 backward.
By arranging the first air guiding section 210 on the air deflector 200 and utilizing the first air guiding section 210 to enable the airflow flowing out of the air outlet through hole 322 to flow towards the preset direction, the air conditioner indoor unit 10 can adjust the flow path of the airflow flowing out of the air outlet through hole 322 while increasing the air outlet area, thereby improving the air supply effect.
In the present embodiment, a gap is formed between the first air guiding section 210 and the air outlet hole 322. The first wind guiding section 210 may be plate-shaped, and is disposed to be inclined downward from front to back so as to be inclined by a first preset angle with respect to a horizontal plane. With such an arrangement, the gap between the first air guiding section 210 and the air outlet through hole 322 may be in a shape of a "bell mouth" gradually expanding from front to back, which may promote the airflow to flow out of the gap quickly, ensure the air outlet amount of the air outlet through hole 322, and further promote the airflow to blow toward the rear lower side of the casing 300. In the wall-mounted type air conditioner indoor unit, since the air conditioner indoor unit 10 is usually hung on a wall, the air flow blown toward the rear lower side of the cabinet 300 may be blown toward the lower side of the cabinet 300 by the shielding effect of the wall and may be blown forward by the shielding effect of the ground to form a circulating wind. The first predetermined angle may be 0 to 30 °.
In some embodiments, the air duct wall 320 where the air outlet hole 322 is located may be substantially flat and is inclined upward from front to back, so that a bell mouth opening between the first air guiding section 210 and the air outlet hole 322 is increased, thereby further increasing the discharge amount of the air flow. In other embodiments, the plate surface of the first wind guiding section 210 may also be disposed parallel to the horizontal plane.
In some embodiments, the air guiding plate 200 further includes a second air guiding section 220 disposed outside the air outlet 310 for guiding the airflow flowing out of the air outlet 310 toward the front upper side of the chassis 300. In this embodiment, the air outlet 310 is located at the bottom side of the front portion of the chassis 300, and the outer side of the air outlet 310 may be the front side thereof.
That is to say, the air guiding plate 200 of the present embodiment includes a plurality of air guiding sections, and each air guiding section has its own air guiding function, which can improve the integration degree of the air guiding plate 200, simplify the structure, and facilitate the synchronous adjustment.
Since the first air guiding section 210 can guide the airflow discharged from the air outlet 322 backward, the second air guiding section 220 can guide the airflow discharged from the air outlet 310 toward the front upper side of the casing 300, and the air conditioner 10 can simultaneously supply air in a plurality of different directions, based on the solution of the present embodiment, the air conditioner 10 is easy to realize a circulating air,
the second wind guiding section 220 may be a plate shape, which is inclined upward from back to front to be inclined at a second preset angle with respect to the horizontal plane. The second preset angle may be 10 to 80 °. That is, the second air guiding section 220 is configured to obliquely blow up the air flowing out of the air outlet 310, and the air can be blown toward the front upper side of the indoor unit 10 of the air conditioner under the guidance of the second air guiding section 220, which can prevent the air from blowing straight to the user due to downward or forward blowing.
In this embodiment, the air deflector 200 has a plurality of air deflecting sections with different directions, and since the air deflector 200 is configured to blow the air flowing through the air outlet duct forward and upward or backward, the air conditioner indoor unit 10 can reduce or prevent the air from blowing directly to the user. The scheme of the embodiment is particularly suitable for the areas with only refrigerating requirements but no heating requirements. When the air conditioner performs a cooling function, the air flow is prevented from blowing directly to the user without excessively adjusting the working angle of the air deflector 200, which is advantageous to simplify the control process of the indoor unit 10 of the air conditioner.
The bottom end of the second air guiding section 220 is lower than the air outlet 310, and the top end of the second air guiding section 220 is higher than the air outlet 310, so that the guiding effect of the second air guiding section 220 for the air flow can be enhanced, the excessive deviation of the flow path of the air flow is reduced or avoided, and the air flow blowing directly to the user is prevented.
The air deflection plate 200 may further include a connecting section 230 connected between the first air deflection section 210 and the second air deflection section 220, so that the air deflection plate 200 forms a single piece. The connecting section 230 extends from the front end of the first wind guiding section 210 to the bottom end of the second wind guiding section 220 in a forward and downward inclination manner.
The wind deflector 200 further includes an arc-shaped section 240 connected between the connecting section 230 and the second wind guiding section 220, so that the connecting section 230 and the second wind guiding section 220 are smoothly connected. By connecting the second air guiding section 220 and the connecting section 230 through the arc-shaped section 240, a smooth airflow flow passage can be formed, which is beneficial to reducing the air supply noise.
The inner surfaces of the connecting section 230, the arc section 240 and the second guiding section 220 can be disposed around the outer side of the air outlet 310. The inner surface of the connecting section 230, the inner surface of the arc-shaped section 240, and the inner surface of the second air guiding section 220 define an air guiding passage. The airflow flowing out of the air outlet 310 flows through the air guiding channel under the guidance of the air guiding plate 200, and then flows into the indoor environment.
The angle between the connecting section 230 and the second wind guiding section 220 is an obtuse angle. The included angle between the connecting section 230 and the second wind guiding section 220 is an included angle between a plane where the connecting section 230 is located and a plane where the second wind guiding section 220 is located. For example, the angle between the connecting section 230 and the second wind guiding section 220 may be 100 to 170 °. Under the condition that the included angle between the connecting section 230 and the second air guiding section 220 is an obtuse angle, the air guiding channel can form a smooth channel, which is beneficial to smooth discharge of air flow.
In some optional embodiments, the air conditioner indoor unit 10 may further include a rotating arm 400, one end of which is fixedly connected to the cabinet 300, and the other end of which is fixedly connected to the inner surface of the connecting section 230, and configured to rotate the connecting section 230, so as to adjust the tilt angles of the first air guiding section 210 and the second air guiding section 220.
That is, the air guiding plate 200 of the present embodiment is movably connected to the chassis 300. For example, the rotating arm 400 may be fixedly connected to the air duct wall 320 inside the air outlet 310.
The rotating arm 400 is utilized to drive the connecting section 230 to rotate, so as to adjust the inclination angles of the first air guiding section 210 and the second air guiding section 220, and air flow can be blown out towards the front upper part and the rear part of the casing 300 along different angles, which can improve the flexibility of the air outlet process of the indoor unit 10 of the air conditioner, and the second air guiding section 220 can be rotated to the position of shielding the air outlet 310 when the air conditioner is turned off, thereby reducing or preventing dust from entering the air outlet duct through the air outlet 310. The rotary arm 400 may be driven by a motor, such as a stepping motor, disposed on the cabinet 300.
When the air conditioner is switched from the shutdown state to the refrigeration state, the air flow can be blown toward the front upper side and the rear side of the casing 300 only by driving the rotating arm 400 to drive the connecting section 230 to move, opening the air outlet 310 by the second air guiding section 220 and opening the air outlet through hole 322 by the first air guiding section 210, and the control process is very simple.
