The wall-mounted air conditioner indoor unit of the present invention does not make the air supply air in the casing (referring to the air flow accelerated by the fan out of the air outlet and used to adjust the indoor environment, such as cold air in the cooling mode, and air in the heating mode). The hot air and the fresh air in the fresh air mode, etc.) are directly blown to the indoor environment through the air outlet, but an air guide hood is buckled on the outer cover of the air outlet, so that the air guide hood can receive part or all of the supply air flow from the air outlet. . In addition, the air guide hood is provided with an upper air outlet and/or a lower air outlet, so as to blow the air supply air upward and/or downward at a more vertical angle, so as to improve the upward blowing/downward blowing effect.

When the indoor unit of the wall-mounted air conditioner of the present invention operates in the cooling mode, the upper air outlet can be selected to discharge air, so as to make the cold air flow more vertically, that is, at a larger upward angle (the angle between the air blowing angle and the horizontal plane) Blow out, avoid the human body, and the cold air flow reaches the highest point and then scatters downward, realizing a "shower-style" cooling experience and improving the user's comfort. When the indoor unit of the wall-mounted air conditioner is running in the heating mode, the air can be discharged from the lower air outlet, so that the hot air can be blown downward and blow directly on the ground at an angle close to the vertical downward angle to achieve a warm foot experience.

In the wall-mounted air conditioner indoor unit of the present invention, an air guide cover is additionally arranged outside the air outlet, and the position of the air guide cover is further forward, so that it can protrude forward from the front surface of the casing, so as to avoid or reduce the casing of the upper air outlet.

Specifically, according to the present invention, the front end of the deflector is pivotally mounted on the air guide hood, so that the rear end of the air guide plate can be rotated to abut against the upper wall of the air guide hood to reach the aforementioned blowing position, or rotated to make Its rear end abuts against the lower wall of the air guide hood to reach the aforesaid downward blowing position, the structure is very simple, the feasibility is high, and the control is also very convenient.

Further, in the wall-mounted air conditioner indoor unit of the present invention, the upper edge of the air outlet constitutes the rear edge of the upper air outlet, that is, the rear edge of the upper air outlet is adjacent to the front surface of the casing. In this way, when the indoor unit of the wall-mounted air conditioner operates in the upward blowing mode, the air supply air blown upward from the upper air outlet will flow upward along the front surface of the cabinet, forming a Coanda effect, so that it can smoothly flow along the front surface of the cabinet. Reach the roof to make the up-blowing effect of the wall-mounted air conditioner indoor unit better.

Further, in the wall-mounted air conditioner indoor unit of the present invention, an upper air guide strip can be arranged at the upper air outlet, which can better guide the air supply air upward, and the structure is very ingenious. In the same way, a lower air guide strip can also be arranged at the lower air outlet, which can better guide the supply air flow downward. Moreover, in the present invention, the shapes of the upper air guide strip and the lower air guide strip are also designed as arc-shaped plates, so as to be more favorable for guiding the wind upward and downward more vertically. At the same time, the upper air guide strip and the lower air guide strip are used to guide the direction of the supply air flow, so that the direction transition process from the air outlet to the upward or downward blowing out the air guide hood is more gentle, reducing the loss of wind resistance and noise.

An embodiment of the present invention provides a wall-mounted air conditioner indoor unit. The wall-mounted air conditioner indoor unit is the indoor part of the split wall-mounted room air conditioner, which is used to regulate indoor air, such as cooling/heating, dehumidification, introducing fresh air, and so on. As shown in FIGS. 1 to 5 , the wall-mounted air conditioner indoor unit according to the embodiment of the present invention may generally include a cabinet 10 and an air guide cover 20 .

The front side of the casing 10 is provided with an air outlet 12 . For example, as shown in FIG. 1 to FIG. 5 , according to a common practice in the field of air conditioning, the air outlet 12 can be opened at the lower front side of the cabinet 10 so as to open toward the front and downward. Of course, the air outlet 12 can also be opened at other positions of the casing 10 . The air outlet 12 is used to discharge the air supply air in the cabinet 10 to the indoor environment, so as to adjust the indoor air. The supply air flow refers to the air flow that is acted by the fan in the casing 10 to accelerate the air flow that flows through the air outlet 12 and is used to adjust the indoor environment, such as cold air in the cooling mode, hot air in the heating mode and air in the fresh air mode. Fresh air, etc. The casing 10 as a whole can be in the shape of a long strip arranged laterally along the longitudinal direction, and the air outlet 12 can be in the form of a long strip with the longitudinal direction parallel to the longitudinal direction of the casing 10 .

The air guide cover 20 covers the air outlet 12 on the outer side of the casing 10 to receive at least part of the air flow discharged from the air outlet 12 . That is, the air guide hood 20 defines a cavity and has an air inlet 21 such that the air inlet 21 is opposite to the air outlet 12 so as to receive the supply air flow discharged from the air outlet 12 . Accepting at least part of the air supply air flow here includes two situations, which specifically refers to that part of the air flow discharged from the air outlet 12 is received by the air guide hood 20, and the other part is directly discharged to the indoor environment; or the entire air flow discharged from the air outlet 12 is made. Both are received by the wind guide cover 20 .

In addition, the air guide hood 20 is also provided with an upper air outlet 22 for discharging the received air flow upward and/or a lower air outlet 23 for discharging the air supply downward. In other words, the air guide hood 20 may be provided with only the upper air outlet 22 , or only the lower air outlet 23 , or both the upper air outlet 22 and the lower air outlet 23 .

The inventors realized that, in the existing wall-mounted air conditioner indoor unit, the air outlet is usually opened in the lower part of the front side of the cabinet, and is opened to the front and downward. In such a solution, due to being obstructed by the front of the cabinet, the air deflector at the air outlet is not convenient to guide the supply air flow in a vertically upward or nearly vertical upward direction. Therefore, the upward angle of the supply air flow is very limited.

However, the wall-mounted air conditioner indoor unit according to the embodiment of the present invention does not directly blow the air flow of the air conditioner to the indoor environment through the air outlet 12 as in the prior art. The air guide hood 20 receives part or all of the air supply air flow from the air outlet 12, and then the air supply air flow is directed upward and downward at a more vertical angle through the upper air outlet 22 and/or the lower air outlet 23 opened on the air guide cover 20. / or blow down. Since the position of the air guide cover 20 is further forward, and "protrudes" outward from the front surface of the casing 10, it can avoid or reduce the blocking of the air flow by the front part of the casing 10 when the upper fan is discharged, so that the air flow can be Blowing upwards at a more vertical angle also makes the upward wind flow more smoothly, which is beneficial to reduce wind resistance and facilitate the air supply with large air volume.

When the indoor unit of the wall-mounted air conditioner of the embodiment of the present invention operates in the cooling mode, the upper air outlet 22 can be selected to discharge the air, so as to make the cold air flow more vertically, that is, at a larger upward angle (the blowing angle of the air and the horizontal plane). The included angle) is blown out to avoid the human body, and the cold air flow reaches the highest point and then scatters downward, realizing a "shower-type" cooling experience and improving the user's comfort. When the indoor unit of the wall-mounted air conditioner operates in the heating mode, the air can be selected from the lower air outlet 23, so that the hot air can be blown downward, so that it can blow directly on the ground at an angle close to the vertical downward, so as to achieve a warm foot experience.

In some embodiments of the present invention, as shown in FIGS. 2 to 5 , an upper air outlet 22 and a lower air outlet 23 can be provided on the air guide hood 20 so that the air can be discharged both upward and downward. In addition, a deflector 26 is provided in the air deflector 20 . The deflector 26 has a passage that cuts off the air outlet 12 and the lower air outlet 23, so that the air supply air is only discharged through the upper air outlet 22, as shown in Figure 4; Passage, so that the blowing air flow is only discharged through the lower air outlet 23, as shown in FIG. 5 . The deflector 26 can be controllably moved to and maintained in the aforementioned blow-up position or blow-down position.

In this way, the indoor unit of the wall-mounted air conditioner has an upward blowing mode and a downward blowing mode for selection, so that the cooling and heating effects are significantly improved.

For example, when the wall-mounted air conditioner indoor unit performs cooling, the aforementioned blow-up mode can be operated. That is, the air guide plate 26 is adjusted to the upward blowing position, as shown in FIG. 4 , so that the air flow in the air guide cover 20 is blown upward through the upper air outlet 22 .

When the indoor unit of the wall-mounted air conditioner is heating, the down-blowing mode can be operated. That is, the air guide plate 26 is adjusted to the downward blowing position, as shown in FIG. 5 , so that the air flow in the air guide hood 20 is blown downward through the lower air outlet 23 .

In the wall-mounted air conditioner indoor unit of the present invention, only one deflector 26 is provided inside the air guide hood 20. By switching the deflector 26 to the upward blowing position or the downward blowing position, the upward blowing mode and the downward blowing mode of the wall-mounted air conditioner indoor unit are realized. The air outlet mode switching between the blowing modes is very ingenious, the structure is very simple and feasible, and the control is very simple and reliable.

In addition, no matter when the wall-mounted air conditioner indoor unit performs cooling or heating, the deflector 26 can be adjusted to an intermediate position between the upward blowing position and the downward blowing position, so that the wind deflector 20 can be upward and downward at the same time. Downward air supply constitutes a maximum air volume air supply mode.

In some preferred solutions, as shown in FIG. 4 , the upper edge (edge E) of the air outlet 12 may constitute the rear edge of the upper air outlet 22 , so that the supply air flow blown upward from the upper air outlet 22 can follow the casing 10 . The front surface flows upwards. In other words, the rear edge of the upper air outlet 22 is brought close to the front surface of the cabinet 10 . In this way, when the indoor unit of the wall-mounted air conditioner operates in the upward blowing mode, the air supply air blown upward from the upper air outlet 22 will flow upward along the front surface of the cabinet 10 to form a Coanda effect, which may also be called sticking. The effect is to flow upward along the front surface of the cabinet 10 to reach the roof more smoothly, so that the upward blowing effect of the wall-mounted air conditioner indoor unit is better. The front surface of the casing 10 can be a flat surface (reduced protruding structures), so that the air supply air can better fit the front surface of the casing 10 and flow upward.

In some embodiments of the present invention, as shown in FIGS. 4 and 5 , the front end (C-end) of the deflector 26 may be pivotally mounted to the wind deflector 20 and configured to be controllably rotated to Make its rear end (D end) abut against the upper wall of the air guide hood 20 to cover the upward blowing position of the lower air outlet 23, as shown in Figure 4; The lower wall is used to cover the downward blowing position of the upper air outlet 22, as shown in FIG. 5 .

In the above-mentioned embodiment, the deflector 26 realizes the position switching function in a rotating manner, the structure is simple, the feasibility is high, and the control is also very convenient. In order to realize the rotation of the deflector 26, a motor (not shown) can be installed on the air deflector 20, and the deflector 26 is driven by the motor to rotate. The motor is preferably a stepper motor, so that its rotation angle is more controllable, thereby making the position of the deflector 26 more controllable.

Of course, in order to save the internal space of the air guide hood 20 and prevent the motor from occupying a lot of space and affecting the passage of the air supply, the motor can also be arranged inside the casing 10, and the motor shaft and the guide plate 26 are connected by a transmission component. to drive the deflector 26 to rotate.

As shown in FIGS. 4 and 5 , a partition 25 can be extended backward from the inner wall of the air guide hood 20 between the upper air outlet 22 and the lower air outlet 23 to separate the interior space of the air guide hood 20 from top to bottom. The partition portion 25 and the main body of the air guide hood 20 can be an integral piece made by an integral molding process. The front end of the deflector 26 is pivotally mounted to the rear end of the partition 25 . In this way, on the one hand, it is convenient to set up a rotating connecting mechanism such as a shaft hole, for example, a hole is opened at the rear end of the partition part 25 to realize the pivotal installation of the deflector 26; on the other hand, the length of the deflector 26 is shortened. , it turns more lightly, and it weighs less to hold it more firmly in the blow-down position.

In some embodiments of the present invention, as shown in FIG. 1 to FIG. 5 , each edge of the air inlet 21 of the air guide hood 20 can be in sealing contact with each edge of the air outlet 12 , so that the air guide hood 20 can receive All the air supply air flowing out from the air outlet 12 is discharged into the room through the upper air outlet 22 or the lower air outlet 23 .

The air guide cover 20 can be detachably installed on the casing 10 by means of screws, clips, etc., and the connecting part of the wind guide cover 20 and the casing 10 is preferably provided with a sealing strip, so that the connection between the two has good sealing performance. , to avoid leakage of supply air flow.

Since the air guide cover 20 is detachably mounted on the casing 10, the air guide cover 20 can be used as an optional component when the air conditioner is shipped and sold, and the user can choose whether to install it.

In some embodiments of the present invention, as shown in FIG. 3 to FIG. 5 , at least one upper air guide bar 222 for guiding the supply air flow upward can be formed at the upper air outlet 22 . The number of the upper air guide strips 222 can be one, preferably multiple, so as to guide the supply air flow more strongly. The upper air guide strip 222 can be an integral piece formed integrally with the air guide hood 20 , or can be an independent part, which is installed on the air guide hood 20 by means of screws, clips, or the like.

In some preferred solutions, each of the upper air guide bars 222 can be formed into an arc-shaped plate that gradually bends upward from the rear to the front, that is, the convex side of the arc-shaped plate is directed toward the front and downward. In this way, when the air supply air flows through the rear surface of the arc-shaped upper air guide bar 222 , it will gradually flow forward and upward along the rear surface of the upper air guide bar 222 and the degree of upward inclination will become larger and larger.

In some preferred solutions, a plurality of upper air guide bars 222 can be provided, and the width of the upper air guide bar 222 relatively close to the air outlet 12 is wider in every two adjacent upper air guide bars 222, so that The air supply air is more guided by the upper air guide strips 222 adjacent to the air outlet 12 , so that the air supply air flows upwards more closely to the front surface of the casing 10 .

Similarly, in some embodiments of the present invention, as shown in FIG. 3 to FIG. 5 , at least one lower air guide bar 232 for guiding the supply air flow downward may be formed at the lower air outlet 23 . The number of the lower air guide strips 232 may be one, preferably a plurality of them, so as to provide stronger guidance to the air supply air. The lower air guide strip 232 can be an integral piece formed integrally with the air guide hood 20 , or can be an independent part, and is installed on the air guide hood 20 by means of screws, clips, or the like.

In some preferred solutions, it is preferable to make each lower air guide bar 232 be in the shape of an arc-shaped plate that gradually bends downward from the rear to the front, that is, the convex side of the arc-shaped plate is directed toward the rear and downward. In this way, when the air supply air flows through the rear surface of the arc-shaped plate-shaped lower air guide bar 232 , it gradually flows forward and downward along the rear surface of the lower air guide bar 232 and the degree of downward inclination becomes larger and larger.

In a word, in the embodiment of the present invention, the upper air guide bar 222 and the lower air guide bar 232 are arranged and the shape is designed as an arc-shaped plate, so as to guide the wind more vertically upward and downward. At the same time, in the embodiment of the present invention, the upper air guide strip 222 and the lower air guide strip 232 are used to guide the direction of the air supply air flow, and the direction of the air supply air flow flowing out from the air outlet 12 is the initial direction, which changes from the initial direction to upward or downward. In the direction of blowing, the direction change process is more gradual, reducing windage loss and noise.

In the preferred embodiment shown in FIGS. 1 to 5 , each of the upper air guide bars 222 and each of the lower air guide bars 232 is integrally formed with the air guide cover 20 . Of course, in some alternative embodiments of the present invention, the upper air guide strip 222 or the lower air guide strip 232 can also be rotatably installed on the air guide cover 20, so as to rotatably adjust the wind direction of the supply air flow.

The number of the upper air outlet 22 can be one, so that the upper air outlet 22 is in the shape of a long strip with a longitudinal direction parallel to the longitudinal direction of the air guide hood 20 . The number of the lower air outlet 23 can be one, so that the lower air outlet 23 is in the shape of a long strip with a longitudinal direction parallel to the longitudinal direction of the air guide hood 20 .

Of course, the number of the upper air outlets 22 can also be multiple, and the plurality of upper air outlets 22 can be arranged in a preset manner, for example, arranged along the length direction of the air guide hood 20 . Further, the air outlet directions of the corresponding upper air guide strips 222 of each upper air outlet 22 can be made different, so that a staggered air supply effect is formed when the air guide cover 20 supplies air upward.

Similarly, the number of the lower air outlets 23 can also be multiple, and the plurality of lower air outlets 23 can be arranged in a preset manner, for example, arranged along the length direction of the air guide hood 20 . The air outlet directions of the corresponding lower air guide strips 232 of each lower air outlet 23 can be further varied, so that a staggered air supply effect is formed when the air guide cover 20 blows air downward.
