Fig. 1 is a structural schematic diagram of a wall-mounted air conditioner indoor unit according to an embodiment of the present invention; Fig. 2 is a sectional enlarged view of the wall-mounted air conditioner indoor unit shown in Fig. 1; Fig. 3 is a wall-mounted air conditioner indoor unit shown in Fig. A schematic diagram of the first wind deflector 51 and the second wind deflector 52 at the converging wind deflecting position.

As shown in FIG. 1 to FIG. 3 , the wall-mounted air conditioner indoor unit according to the embodiment of the present utility model may generally include a housing 10 , a first wind deflector 51 , a second wind deflector 52 and a driving mechanism 30 .

The casing 10 defines an air outlet 12 . The casing 10 defines an accommodating space for accommodating main components of the wall-mounted air conditioner indoor unit, such as a fan, an indoor heat exchanger, swing leaves, and the like. The air outlet 12 can be provided at the lower front side of the housing 10 to open forward and downward. The air outlet 12 is used to exhaust the conditioned airflow in the housing 10 to the indoor environment, so as to adjust the indoor air. The regulated air flow is heat exchange air flow, humidification air flow, washing air flow, fresh air flow and the like. The casing 10 may be in the shape of a strip whose length direction is horizontally arranged, and the air outlet 12 may be in the shape of a strip whose length direction is parallel to the length direction of the casing 10 .

The first wind deflector 51 and the second wind deflector 52 are arranged side by side at the air outlet 12 , and the rotation axes of the two are parallel to each other. Preferably, the rotation axes of the first wind deflector 51 and the second wind deflector 52 are parallel to the length direction of the air outlet 12 , that is, horizontally and transversely.

The driving mechanism 30 is used to drive the first wind deflector 51 and the second wind deflector 52 to rotate in opposite directions, so that the first wind deflector 51 and the second wind deflector 52 have a gradual wind direction along the air outlet 12 . The convergent wind guide position is close, as shown in Figure 3; and the divergent wind guide position is gradually away from the air outlet direction, as shown in Figure 4.

As shown in Figure 3, at the convergent air guide position, the first air guide plate 51 and the second air guide plate 52 gradually approach along the air outlet direction of the air outlet 12, and a tapered flow channel is formed between the two, and the air flow of the air outlet When passing through the tapered flow channel, it is gradually compressed to form a polymerization effect. The wind force of the aggregated airflow is stronger and the air supply distance is longer, which is suitable for directional and strong air supply.

As shown in Figure 4, at the divergent air guide position, the first air guide plate 51 and the second air guide plate 52 gradually move away from each other along the air outlet direction of the air outlet 12, so that the air flow is divided into multiple streams and scattered, and then the wall-mounted air conditioner The front of the indoor unit converges at a distance to form an enveloping air supply effect, which makes the user's wind experience more comfortable and reduces the discomfort of direct blowing. Specifically, as shown in FIG. 4 , for the scheme that the air outlet 12 is open to the front and the bottom, the first air guide plate 51 can be made close to the upper edge of the air outlet 12 , and the second air guide plate 52 can be made close to the lower edge of the air outlet 12 . In the divergent air guide position, the first air guide plate 51 guides the airflow above it forward or forward, and the second air guide plate 52 guides the airflow behind it downward. The first air guide plate 51 and the second air guide plate The air-flow between 52 is blown out towards the front and the bottom. In this way, the airflow is divided into three and gradually dispersed to flow out, the wind becomes weaker, making the human body feel more comfortable. Moreover, the airflow above the first air deflector 51 sinks gradually during the forward flow process, and finally merges with other airflows to form an enveloping effect.

In some embodiments, as shown in FIG. 2 to FIG. 4 , the first wind deflector 51 and the second wind deflector 52 can be curved plates with one side concave and the other side convex. For example, the first wind deflector 51 and the second wind deflector 52 can be made to be arc-shaped plates whose center line is parallel to their own rotation axis, so as to facilitate processing. Of course, the first wind deflector 51 and the second wind deflector 52 may also be non-curved plates.

When the first wind deflector 51 and the second wind deflector 52 are in the converging wind deflecting position, the inner concave sides of the two face each other, as shown in FIG. 3 , so that the airflow between the two is more strongly converged. When the first wind deflector 51 and the second wind deflector 52 are in the divergent wind deflecting position, the convex sides of the two face each other. Taking FIG. 4 as an example, such arrangement can make the air flow above the first wind deflector 51 be lifted up. Guide, so that the airflow behind the second wind deflector 52 can be guided downward as much as possible, and the airflow between the first wind deflector 51 and the second wind deflector 52 can be more dispersed.

In some embodiments, the first wind deflector 51 and the second wind deflector 52 can also have a wind-shielding position with their convex sides facing the outside of the housing 10 , as shown in FIG. 2 . In the wind-shielding position, there is a wind outlet space between the first wind deflector 51 and the second wind deflector 52 and between the two and the edge of the air outlet 12 . In this way, the outlet air is allowed to blow out through these narrow air outlet intervals, and the air flow is weaker, forming a breeze effect and making the human body feel more comfortable.

When the indoor unit of the wall-mounted air conditioner is in a shutdown state, the first wind deflector 51 and the second wind deflector 52 can also be switched to the wind-shielding position. In addition, a rotatable outer wind deflector can be provided at the air outlet 12 for opening or closing the air outlet 12 .

Fig. 5 is a schematic block diagram of an air conditioner in an embodiment of the present invention.

In some embodiments, as shown in FIG. 5 , the wall-mounted air conditioner indoor unit may further include a human sensing module 200 and a control module 100 .

The human sensing module 200 is used for sensing the body surface temperature of the human body. The control module 100 is electrically connected with the human sensing module 200 and the driving mechanism 30 , and is used to control the driving mechanism 30 according to the body surface temperature of the human body, so as to adjust the air guiding positions of the first air deflector 51 and the second air deflector 52 .

For example, in the cooling mode, when the body surface temperature of the human body is lower than the first preset temperature, the control module 100 controls the driving mechanism 30 to drive the first air deflector 51 and the second air deflector 52 to the aforementioned diverging deflector. Wind position, to avoid strong cold wind directly blowing the human body. When the body surface temperature of the human body is higher than the second preset temperature, the control module 100 controls the driving mechanism 30 to drive the first wind deflector 51 and the second wind deflector 52 to the above-mentioned converging wind deflecting position, so that the cold wind aggregates and blows out , to speed up the cooling speed.

In the heating mode, when the body surface temperature of the human body is higher than the third preset temperature, the control module 100 controls the driving mechanism 30 to operate to drive the first air deflector 51 and the second air deflector 52 to the aforementioned divergent air deflector. position to avoid strong hot air blowing directly on the human body. When the body surface temperature of the human body is lower than the third preset temperature, the control module 100 controls the driving mechanism 30 to drive the first wind deflector 51 and the second wind deflector 52 to the aforementioned converging wind deflecting position, so that the hot air is aggregated and blown out , to speed up the heating speed.

As shown in FIGS. 5 and 6 , in some embodiments, the driving mechanism 30 includes a first gear 31 , a second gear 32 , a third gear 33 , a fourth gear 34 and a motor 35 .

Wherein, the first gear 31 is installed on the first wind deflector 51 . The second gear 32 is installed on the second wind deflector 52 . The third gear 33 is used to mesh with the first gear 31 . The fourth gear 34 is used to mesh with the second gear 32 and the third gear 33 . The motor 35 is used to directly or indirectly drive the third gear 33 or the fourth gear 34 to rotate, so that the first gear 31 and the second gear 32 rotate oppositely. As shown in FIG. 1 and FIG. 6 , the housing 10 includes a panel 14 and a skeleton 15 , and the skeleton 15 constitutes a structural main body of the housing 10 for defining an air duct 150 . The panel 14 covers the outer side of the framework 15 to form the appearance of the casing 10 . As shown in FIG. 7 , the first gear 31 , the second gear 32 , the third gear 33 , the fourth gear 34 and the motor 35 can be attached to the frame 15 .

For example, FIG. 6 shows a scheme in which the motor 35 directly drives the fourth gear 34: the rotating shaft of the motor 35 is fixedly connected to the fourth gear 34 so as to directly drive the fourth gear 34 to rotate. An intermediate gear (the third gear 33 ) is also included between the first gear 31 and the drive wheel (the fourth gear 34 ), which has been reversed twice, so its steering is the same as that of the fourth gear 34 . The second gear 32 is in direct mesh with the drive wheel (the fourth gear 34 ), and its direction of rotation is opposite to that of the fourth gear 34 . As a result, the rotation of the second gear 32 is opposite to that of the first gear 31 . Of course, other transmission gears can also be arranged between the motor 35 and the fourth gear 34 to form a scheme of indirectly driving the fourth gear 34 . The number of teeth of the first gear 31, the second gear 32 and the third gear 33 are equal and less than the number of teeth of the fourth gear 34, so as to form a deceleration effect, to allow the higher speed of the motor 35, to facilitate control, and to make the first wind guide The rotation speeds of the plate 51 and the second wind guide plate 52 are equal, so as to adjust the angle.

The plate 51 and the second air deflector 52 are adjusted from the converging air supply position to the divergent air supply position, and the first air deflector 51 and the second air deflector 52 are adjusted from the divergent air supply position to the convergent air supply position by reversing. It should be understood that the forward rotation and reverse rotation of the motor 35 are opposite, but which direction the motor 35 rotates is forward rotation and which direction is reverse rotation is only an artificial definition.
