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 adjust the indoor air, such as cooling/heating, dehumidification, introducing fresh air, and so on.

As shown in FIGS. 1 to 8 , 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 plate 20 .

The casing 10 is provided with an air outlet 12 for discharging the air supply air in the casing 10 to the room. The supply air flow can be cold air produced by the wall-mounted air conditioner indoor unit in cooling mode, or hot air produced in heating mode, or fresh air introduced in fresh air mode, or purified air generated in purification mode, etc. Wait. The casing 10 can be a horizontally extending elongated structure as a whole.

The wind deflector 20 is disposed outside the air outlet 12 . The wind deflector 20 includes an upper deflector 21 and a lower deflector 22 arranged up and down. The upper baffle 21 and the outer peripheral surface of the casing 10 define an upper channel 212 that opens upward, and the opening angle of the upper channel 212 can be rotatably adjusted around its bottom end. Referring to FIG. 4 , if the upper deflector 21 is rotated forward, the upper end thereof will be further away from the casing 10 , so that the opening angle thereof will be increased. In the state of FIG. 4 , the opening angle of the upper channel 212 is already relatively large. If the upper deflector 21 is rotated backward, the upper end thereof will be closer to the casing 10, so that the opening angle thereof will be reduced. Similarly, the lower baffle 22 and the outer peripheral surface of the casing 10 define a lower channel 222 that opens downward, and the opening angle of the lower channel 222 can be rotatably adjusted around its top end. Referring to FIG. 8 , if the lower deflector 22 is rotated forward, its bottom end will be further away from the casing 10 , and the opening angle will be increased. In the state of FIG. 8 , the opening angle of the lower channel 222 is already relatively large. If the lower deflector 22 is rotated backward, its bottom end will be closer to the casing 10, so that the opening angle thereof will be reduced.

The air deflector 20 is installed on the casing 10 in a translational manner up and down, so as to be movable to connect the upper channel 212 with the air outlet 12 so that the air flow discharged from the air outlet 12 flows upward along the outer peripheral surface of the casing 10 . Up blowing position, as shown in Figure 1 to Figure 5. Alternatively, the air deflector 20 is moved to a blow down position where the lower channel 222 is communicated with the air outlet 12 so that the air flow can flow downward along the outer peripheral surface of the cabinet 10 , as shown in FIGS. 6 to 8 .

In this way, the indoor unit of the wall-mounted air conditioner has an upward blowing mode and a downward blowing mode to choose from, so that its cooling and heating effects are significantly improved. For example, when the air-conditioning cooling needs to operate in the blow-up mode, the air guide cover plate 20 is moved to the blow-up position, as shown in FIG. 1 to FIG. 4 . After the air flow (cold air) inside the casing 10 is blown out from the air outlet 12 , it is blocked by the upper deflector 21 and cannot be directly blown out horizontally, but is blown upward along the outer peripheral surface of the casing 10 . When the air-conditioning heating needs to operate in the downward blowing mode, move the air guide cover plate 20 to the downward blowing position, as shown in FIGS. 5 to 8 , so that the supply air flow (hot air) cannot be directly It blows out horizontally, but flows downward along the outer peripheral surface of the cabinet 10 .

Since the air supply air flows upward or downward against the outer peripheral surface of the casing 10, a Coanda effect (also referred to as an attachment effect) can be formed, so that the outer peripheral surface of the casing 10 can smoothly reach the roof or the ground, forming a The shower-type air supply effect and the carpet-type air supply effect make the cooling or heating effect of the wall-mounted air conditioner indoor unit better, and at the same time, it can also avoid cold or hot air blowing people and causing human discomfort. In addition, in the embodiment of the present invention, the opening angle of the upper channel 212 and the lower channel 222 can be adjusted by rotating the upper deflector 21 and the lower deflector 22, thereby adjusting the air flow, air speed and air angle range.

In addition, the wind deflector 20 can also be configured to be movable to a position where both the upper channel 212 and the lower channel 222 are communicated with the air outlet 12 (not shown, that is, the wind deflector 20 is located in the position in FIG. 4 and FIG. 4 ). 8), to guide the air supply air respectively, so that the indoor unit of the wall-mounted air conditioner can supply air in both directions at the same time, and improve the air conditioning speed.

In some embodiments, the area of the outer peripheral surface of the casing 10 through which the supply air flows can be a flat surface, so that the supply air flow can better fit the outer peripheral surface of the casing 10 . As shown in FIG. 1 , for the solution in which the air outlet 12 is opened on the front side of the casing 10 , the front surface of the casing 10 , that is, the outer peripheral surface through which the fresh air flows, can make the front surface of the casing 10 a flat surface.

In some embodiments, as shown in FIG. 5 , the lower section 210 of the upper deflector 21 is a curved section that is gradually bent toward the air outlet 12 from top to bottom. The upper section 220 of the lower deflector 22 is a curved section that is gradually bent toward the air outlet from bottom to top.

When the wind deflector 20 is in the upward blowing mode, the rear end of the upper deflector 21 can be connected to the lower wall of the air duct 40 , referring to FIG. 4 . Since the rear end of the upper deflector 21 is a curved section, its inner surface is equivalent to the extension of the lower wall of the air duct 40 , so that the air flow from the air duct 40 enters the upper deflector 21 smoothly and with low resistance. guide range. Similarly, when the air deflector 20 is in the downward blowing mode, the upper end of the lower deflector 22 can be connected to the upper wall of the air duct 40 , referring to FIG. 8 . Since the upper end of the lower deflector 22 is a curved section, its inner surface is equivalent to the extension of the upper wall of the air duct 40 , so that the supply air flow from the air duct 40 enters the lower deflector 22 smoothly and with low resistance. guide range.

Further, the curved section of the upper deflector 21 can be made into an arc shape, and the rotation axis x1 of the upper deflector 21 is collinear with the central axis of the arc, so that the upper deflector 21 is rotating, and its outer surface ( The distance between the arc surface) and the lower deflector 22 remains unchanged, so as to avoid interference between the lower end of the upper deflector 21 and the lower deflector 22 . Similarly, the curved section of the lower deflector 22 is arc-shaped, and the rotation axis x2 of the lower deflector 22 is collinear with the central axis of the arc, which can prevent the lower end of the lower deflector 22 from rotating with the upper deflector. The plate 21 interferes.

In some embodiments, as shown in FIGS. 1 to 8 , the entire front surface of the casing 10 can be a vertical plane (the front surface of the casing 10 is a part of the outer peripheral surface of the casing 10 ), specifically, it can be A vertical plane or a curved surface such as an arc surface whose axis extends vertically. The air outlet 12 may be opened at the lower portion of the front surface of the casing 10 . More specifically, the air outlet 12 may be a long strip with a longitudinal direction parallel to the lateral direction of the cabinet 10 .

Referring to FIG. 5 , the ratio of the distance (de) between the lower edge d of the air outlet 12 and the bottom end e of the front surface of the casing 10 and the width (cd) of the air outlet 12 is greater than 1/2, that is, de/cd>1/ 2, preferably greater than 3/4. In this way, when the indoor unit of the wall-mounted air conditioner operates in the downward blowing mode, the front surface of the casing 10 below the lower edge of the air outlet 12 has a sufficient length to guide the supply air to flow downward and enhance the Coanda effect. In addition, the width of the lower deflector 22 (the distance from the top end to the bottom end) can also be made larger than the width of the upper deflector 21, that is, the lower deflector 22 can be made wider, so as to better guide the airflow in the downward blowing mode Blow down to make up for the short guiding distance (ie, de) of the front surface of the casing on the lower side of the air outlet 12 .

In some embodiments, as shown in FIG. 1 to FIG. 8 , the wind deflector 20 further includes two mounting plates 23 arranged at intervals, and the two mounting plates 23 can be mounted on the casing 10 in an up-and-down translational manner. The upper deflector 21 and the lower deflector 22 are both located between the two mounting plates 23 and are respectively rotatably mounted on the two mounting plates 23 . That is, the wind deflector 20 includes an upper deflector 21 , a lower deflector 22 and two mounting plates 23 . The upper deflector 21 and the lower deflector 22 are installed on the mounting plate to guide the supply air flow, and the two mounting plates 23 are used to realize the moving connection with the casing 10, without the need for the upper deflector 21 or the lower deflector A moving drive mechanism is set on the plate 22, which will not affect the wind guide.

One of the mounting plates 23 may be provided with two motors (not shown) for respectively driving the upper deflector 21 and the lower deflector 22 to rotate.
