The embodiment of the utility model provides a wall-hanging air conditioning indoor set. The indoor unit of the wall-mounted air conditioner is the indoor part of the split wall-mounted room air conditioner and is used for regulating indoor air, including refrigeration, heating, purification, humidity regulation, fresh air introduction and the like.

Fig. 1 is a schematic structural view of a wall-mounted air conditioner indoor unit according to an embodiment of the present invention; fig. 2 is an enlarged sectional view of the wall-mounted air conditioning indoor unit shown in fig. 1; fig. 3 is a schematic view of the wall-mounted air conditioning indoor unit shown in fig. 2, in which the first air deflector 51 and the second air deflector 52 are in the converging air guiding position.

As shown in fig. 1 to 3, a wall-mounted air conditioning indoor unit according to an embodiment of the present invention may generally include a casing 10, a first air deflector 51, a second air deflector 52, and a driving mechanism 30.

The housing 10 is opened with an air outlet 12. The casing 10 defines an accommodation space to accommodate main components of a wall-mounted air conditioning indoor unit, such as a fan, an indoor heat exchanger, a swing vane, and the like. The outlet 12 may be opened at a lower front portion of the housing 10 to open toward a front lower portion. The outlet 12 is used to discharge the conditioned air flow in the housing 10 to the indoor environment to condition the indoor air. The conditioning air flow is heat exchange air flow, humidifying air flow, washing air flow, fresh air flow and the like. The housing 10 may be a long strip with a length direction horizontally and transversely disposed, and the air outlet 12 may be a long strip with a length direction parallel to the length direction of the housing 10.

The first air deflector 51 and the second air deflector 52 are arranged side by side at the air outlet 12, and the rotation axes of the first air deflector and the second air deflector 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 wind outlet 12, i.e. horizontal transverse direction.

The driving mechanism 30 is configured to drive the first air guiding plate 51 and the second air guiding plate 52 to rotate in opposite directions, so that the first air guiding plate 51 and the second air guiding plate 52 have converging air guiding positions gradually approaching to each other along the air outlet direction of the air outlet 12, as shown in fig. 3; and has a divergent air guiding position gradually far away from the air outlet direction, as shown in fig. 4.

As shown in fig. 3, in the convergent air guiding position, the first air guiding plate 51 and the second air guiding plate 52 gradually approach to each other along the air outlet direction of the air outlet 12, a tapered flow passage is formed therebetween, the air outlet flow is gradually compressed when flowing through the tapered flow passage, so as to form a convergent effect, the wind power of the converged air flow is stronger, the air supply distance is longer, and the convergent air flow is suitable for directional powerful air supply.

As shown in fig. 4, in the divergent air guiding position, the first air guiding plate 51 and the second air guiding plate 52 are gradually far away from the air outlet direction of the air outlet 12, so that the air flow is dispersed and flows out in multiple strands, and then converges in the far front of the wall-mounted air conditioner indoor unit, thereby forming an encircling air supply effect, so that the user experiences more comfortably, and the discomfort of direct blowing is reduced. Specifically, as shown in fig. 4, for the solution that the air outlet 12 is opened forward and downward, the first air deflector 51 may be close to the upper edge of the air outlet 12, and the second air deflector 52 may be close to the lower edge of the air outlet 12. In the divergent air guiding position, the first air guiding plate 51 guides the air flow above the first air guiding plate forward or forward and upward, the second air guiding plate 52 guides the air flow behind the first air guiding plate downward, and the air flow between the first air guiding plate 51 and the second air guiding plate 52 is blown out forward and downward. Thus, the airflow is divided into three parts and gradually and dispersedly flows out, wind force is weakened, and the human body feels more comfortable. And the air flow above the first air deflector 51 sinks gradually in the forward flowing process and finally joins with other air flows to form the surrounding effect.

In some embodiments, as shown in fig. 2 to 4, the first wind deflector 51 and the second wind deflector 52 may be curved plates with one side concave and the other side convex. For example, the first air guiding plate 51 and the second air guiding plate 52 may be arc plates with center lines parallel to their rotation axes, so as to facilitate the manufacturing process. Of course, the first air guiding plate 51 and the second air guiding plate 52 may be non-arc-shaped plates.

When the first wind deflector 51 and the second wind deflector 52 are in the converging wind guiding position, the concave sides of the two are opposite, as shown in fig. 3, so that the converging force of the air flow between the two is stronger. When the first air deflector 51 and the second air deflector 52 are in the divergent air guiding position, the convex sides of the two are opposite, and taking fig. 4 as an example, the arrangement can enable the air flow above the first air deflector 51 to be upwards guided, enable the air flow behind the second air deflector 52 to be downwards guided as much as possible, and enable the air flow between the first air deflector 51 and the second air deflector 52 to be more dispersed.

In some embodiments, the first wind deflector 51 and the second wind deflector 52 may further have a wind shielding position in which the convex sides thereof are both directed to the outside of the casing 10, as shown in fig. 2. In the wind shielding position, there are wind-out intervals between the first wind deflector 51 and the second wind deflector 52 and between the first wind deflector and the second wind deflector and the edge of the wind outlet 12. Therefore, the air outlet flow is allowed to be blown out through the narrow air outlet intervals, the air flow is weaker, a breeze effect is formed, and the human body feels more comfortable.

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

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

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

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

For example, in the cooling mode, when the body surface temperature of the human body is lower than the first predetermined temperature, the control module 100 controls the driving mechanism 30 to operate, so as to drive the first air guiding plate 51 and the second air guiding plate 52 to the diverging air guiding position, thereby preventing the strong cold wind from 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 operate, and drives the first air deflector 51 and the second air deflector 52 to the aforementioned converging air guiding position, so as to converge and blow out the cold air, and accelerate 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, so as to drive the first air guiding plate 51 and the second air guiding plate 52 to the aforementioned diverging air guiding position, thereby preventing the strong hot air from directly blowing 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 operate, and drives the first air deflector 51 and the second air deflector 52 to the aforementioned converging air guiding position, so that the hot air is converged and blown out, and the heating speed is increased.

Fig. 6 is a schematic view of the framework 15, the driving mechanism 30, and the first and second air deflectors 51 and 52 of the wall-mounted air conditioning indoor unit shown in fig. 1; fig. 7 is an enlarged view of fig. 6 at a.

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

The first gear 31 is mounted on the first air deflector 51. The second gear 32 is mounted to the second air deflection plate 52. The third gear 33 is for meshing with the first gear 31. The fourth gear 34 is for meshing 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 in opposite directions. As shown in fig. 1 and 6, the housing 10 includes a panel 14 and a skeleton 15, and the skeleton 15 constitutes a structural body of the housing 10 and defines an air duct 150. The panel 14 covers the outside of the frame 15 and serves to form the appearance of the housing 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 may 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 (third gear 33) is also included between the first gear 31 and the driving wheel (fourth gear 34), and the direction of rotation is the same as that of the fourth gear 34 after two reversals. The second gear 32 is directly meshed with a driving wheel (fourth gear 34), and the rotation direction thereof is opposite to that of the fourth gear 34. Thereby, the second gear 32 is rotated in the opposite direction to the first gear 31. Of course, other transmission gears may be disposed 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 is equal to and less than that of the fourth gear 34, so as to form a speed reduction effect, so as to allow the rotation speed of the motor 35 to be higher, so as to facilitate control, and to equalize the rotation speeds of the first air deflector 51 and the second air deflector 52, so as to facilitate angle adjustment.

In other embodiments, the motor 35 may directly or indirectly drive the third gear 33, and the second gear 32 and the first gear 31 may also rotate in opposite directions, which is not described in detail herein.

The motor 35 is a stepping motor which can be controlled to rotate forward and backward, so that the rotation angle control is more accurate, the positions of the first air deflector 51 and the second air deflector 52 can be accurately adjusted, the first air deflector 51 and the second air deflector 52 can be adjusted from the converged air supply position to the diverged air supply position through forward rotation, and the first air deflector 51 and the second air deflector 52 are adjusted from the diverged air supply position to the converged air supply position through reverse rotation. It should be understood that the forward rotation and the reverse rotation of the motor 35 are opposite, but the direction in which the motor 35 rotates is the forward rotation and the direction in which the motor 35 rotates is the reverse rotation are merely defined artificially.

In other embodiments, the rotational ranges of the first wind deflector 51 and the second wind deflector 52 can be both larger than 360 °, and if the motor 35 can always rotate in one direction, the switching between the converging air supply position and the diverging air supply position can be realized.

In some embodiments, as shown in fig. 2, the wall-mounted air conditioning indoor unit may be an indoor portion of a split wall-mounted room air conditioner that utilizes a vapor compression refrigeration cycle system for cooling/heating. For example, as shown in fig. 2, an indoor heat exchanger 60 and a fan 70 are provided inside the casing 10. The indoor heat exchanger 60 and the throttle device are connected to a compressor, an outdoor heat exchanger and other refrigeration components disposed inside the outdoor unit of the air conditioner through pipes, thereby forming a vapor compression refrigeration cycle system. Under the action of the fan 70, the indoor air enters the inside of the casing 10 through the air inlet 11 at the top of the casing 10, and after the forced convection heat exchange with the indoor heat exchanger 60 is completed, heat exchange air is formed. The heat-exchange air is directed by the air duct 150 to the outlet 12. The fan 70 is preferably a cross flow fan having an axis parallel to the length of the housing 10, and is disposed at the inlet of the air duct 150. The indoor heat exchanger 60 may be a three-stage heat exchanger.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and interpreted to cover all such other variations or modifications.
