Fig. 4 is the M-M sectional view of Fig. 2; Fig. 5 is the enlarged view of A of Fig. 4;

As shown in FIG. 1 to FIG. 6 , the wall-mounted air conditioner indoor unit according to the embodiment of the present invention may generally include a casing 10 , two mounting seats 90 and an air guide cover plate 20 .

The front side of 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 the cooling mode, hot air produced in the heating mode, or fresh air introduced in the fresh air mode, or purified air generated in the purification mode, etc. . The casing 10 can be a horizontally extending elongated structure as a whole.

The two mounting bases 90 are respectively mounted on the end covers 106 on both lateral sides of the casing 10 . The outer walls of the two end caps 106 constitute the appearance of the left and right sides of the casing 10 .

The wind deflector 20 includes a front section 201 extending laterally in front of the air outlet 12 and two bent sections 202 extending rearward from both ends of the front section 201 . The rear end of each bending section 202 is mounted on a mounting seat 90 so as to be movable back and forth. The air guide cover plate 20 and the outer peripheral surface of the casing 10 define an air guide channel 21 . That is, the air guide cover plate 20 is parallel or nearly parallel to the outer peripheral surface of the casing 10 , and the space between them constitutes the air guide channel 21 . The air guide channel 21 is used for guiding the air supply air flowing out of the air outlet 12 to flow upward and/or downward along the outer peripheral surface of the cabinet 10 . That is, after being blown out from the air outlet 12 of the casing 10, the supply air flow (such as cold air, hot air, fresh air, or purified air) is blocked by the inner wall of the air guide cover plate 20 and cannot be directly blown out horizontally, but along the casing. The periphery of 10 is blown up and/or down. The upward and/or downward blowing here means that the supply air flow can be blown out only upwards, or only downwards, or both upwards and downwards. Figures 1 to 5 illustrate the situation in which the air supply air is blown upward, and Figures 6 to 8 illustrate the solution in which the air supply air is blown out downward.

Since the air supply air flows upwards or downwards against the outer peripheral surface of the casing 10, a Coanda effect (also referred to as a sticking effect) can be formed, so that the outer peripheral surface of the casing 10 can reach the roof or the ground smoothly, so that the The cooling or heating effect of the wall-mounted air conditioner indoor unit is better. At the same time, it can also avoid the discomfort caused by cold or hot wind.

In some embodiments, the area on 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 . For example, 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.

Since the bent section 202 of the wind deflector 20 is installed on the mounting seat 90 so as to be movable back and forth, the entire wind deflector 20 can be translated back and forth, so that the width of the wind deflector 21 (that is, the wind deflector plate) can be changed as required. The distance between 20 and the outer peripheral surface of the casing 10 is marked as B) in FIG.

Specifically, after the distance B is increased, the air outlet section of the air guide channel 21 becomes larger, the air outlet is smoother, and the air outlet volume is larger, as shown in FIG. 6 , where B1>B in FIG. 6 . When the distance B is reduced, the air outlet section of the air guide channel 21 becomes smaller, and the air outlet volume becomes smaller, as shown in FIG. 1 to FIG. 5 . The embodiment of the present invention realizes the adjustment of the air output by adjusting the position of the air guide cover plate 20 , and satisfies the adjustment requirements for the air output in different operating conditions or scenarios.

7 is a schematic diagram of the wall-mounted air conditioner indoor unit shown in FIG. 1 when switched to a blowdown mode; FIG. 8 is a schematic front view of the wall-mounted air conditioner indoor unit shown in FIG. 7 ;

In some embodiments, as shown in FIGS. 1 to 9 , the two mounting bases 90 can be mounted on the end cover 106 so as to translate up and down, so that the wind deflector plate 20 can translate up and down with the two mounting bases 90 . In addition, the wind deflector 20 has a partition portion 23 protruding from the inner surface thereof toward the outer peripheral surface of the cabinet 10 . The partition part 23 is used to partition the air guide channel 21 into an upper channel 212 with an upward opening and a lower channel 214 with an opening downward. The air baffle plate 20 is configured to: move with the mounting seat 90 to a position where the partition 23 is located above the air outlet 12, so as to guide the supply air flow downward by the lower channel 214, as shown in FIGS. 7 to 9; or with the mounting seat 90 is moved to a position where the partition 23 is located below the air outlet 12 to guide the supply air flow upward by the upper channel 212, as shown in FIGS. 1 to 6 .

In this way, the indoor unit of the wall-mounted air conditioner has an upward blowing mode and a downward blowing mode for the system or the user to choose, so that the cooling and heating effects are significantly improved. For example, when the air conditioner needs to operate in the downward blowing mode, the air deflector 20 is moved to the position where the partition 23 is located above the air outlet 12, and the air flow is guided downward by the lower channel 214, as shown in FIG. 9 . When the air-conditioning cooling needs to operate in the upward blowing mode, the air deflector 20 is moved to a position where the partition 23 is located below the air outlet 12, and the upper channel 212 guides the supply air upward, as shown in FIG. 4 .

Of course, the air deflector 20 can also be moved to a position between the upward blowing mode and the downward blowing mode, so that both the upper channel 212 and the lower channel 214 are communicated with the air outlet 12, so that the air flow from the air outlet 12 is One part is guided upward by the upper channel 212, and the other part is guided downward by the lower channel 214, so as to supply air upward and downward at the same time, increasing the air conditioning speed.

As shown in FIG. 1 and FIG. 12 , each bending section 202 can have a wind shield 2021 extending toward the end cover 106 , so that the inner side of the wind shield 2021 abuts against the outer wall of the end cover 106 for blocking the feeding The air flow flows backwards, so that the supply air flow can flow upward or downward better, avoiding the diffusion of backward flow and affecting the upward and downward wind force.

In some embodiments, please refer to FIGS. 4 and 5 , the partition 23 has a tip 230 adjacent to the outer peripheral surface of the casing 10 . The tip 230 is close to the outer peripheral surface of the casing 10 , so that it can fit with the outer peripheral surface of the casing 10 . When the air deflector 20 is in the blowing position, the sealing performance between the partition 23 and the outer peripheral surface of the casing 10 is better, so as to prevent the airflow from leaking downward; when the air deflector 20 is in the downward blowing position, the partition The sealing performance between 23 and the outer peripheral surface of the casing 10 is better, and the upward leakage of the air flow is avoided. Of course, if the tip 230 is too close to the outer surface of the casing 10 , when the wind deflector 20 moves up and down, the tip 230 and the outer surface of the casing 10 may rub against each other, which may generate relatively large noise. To avoid this noise, a certain gap can also be reserved between the tip 230 and the outer surface of the casing 10 .

Please refer to FIGS. 4 and 5 , the upper surface 231 of the partition 23 starts from the tip 230 , extends away from the casing 10 and slopes upward gradually, and is tangent to the inner surface of the rest of the air guide hood 20 . Concave surface. Similarly, the lower surface 232 of the partition portion 23 is a concave arc surface that starts from the tip 230 , extends away from the casing 10 and slopes downward gradually, and is tangent to the inner surface of the rest of the air baffle plate 20 . . In this way, when the supply air flow is blown out from the air outlet 12 and then turned upward or downward, it will be gradually turned along the upper or lower surface of the partition 23, the process is more moderate, and the wind loss and noise are smaller.

When the air deflector 20 is in the upward blowing mode, the tip 230 of the partition 23 can be positioned opposite to the lower edge of the air outlet 12, so that the upper surface 231 of the partition 23 is in contact with the lower wall of the air duct 40, refer to Figure 4. In addition, since the upper surface 231 of the partition portion 23 is a concave arc surface, the upper surface 231 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 smoothly and with low resistance. The guide range of the partition 23 .

Similarly, when the air deflector 20 is in the downward blowing mode, the tip 230 of the partition 23 can be positioned opposite to the upper edge of the air outlet 12 so that the lower surface 232 of the partition 23 is in contact with the upper wall of the air duct 40 Next, refer to Figure 9. Since the lower surface 232 of the partition part 23 is a concave arc surface, the lower surface 232 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 partition part smoothly and with low resistance 23 boot range.

In some embodiments, as shown in FIGS. 1 to 9 , 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 can be opened on the front surface of the casing 10 , and specifically can be the lower part 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 distance between the partition portion 23 and the bottom end of the air deflector plate 20 can also be made larger than the distance between the partition portion 23 and the top end of the air deflector plate 20 (specifically, the tip 230 of the partition portion 23 can be used as the measurement reference), that is, the partition portion 23 It is located on the upper part of the air deflector plate 20 so as to better guide the airflow to blow down in the downward blowing mode, making up for the short guiding distance (ie de) of the front surface of the casing on the lower side of the air outlet 12.

When the second motor 71 drives the second gear 72 to rotate, the second gear 72 drives the second rack 73 to translate up and down, so as to drive the mounting base 90 to translate up and down.

Specifically, as shown in FIGS. 13 to 14 , a mounting member 107 can be fixed on the inner wall of the end cover 106 . The mounting member 107 is connected with a plurality of mounting portions 1062 provided on the inner wall of the end cover 106 by screws through a plurality of mounting portions 1072 provided thereon. Two vertically extending slide rails 1071 are formed on the mounting member 107 . Two sliding grooves 731 with opposite opening directions are formed at both ends of the second rack 73 in the width direction, each sliding groove 731 is matched with a sliding rail 1071 to allow the second rack 73 to slide up and down along the mounting member 107 . That is, the role of the mounting member 107 is to form the slide rail 1071 for the second rack 73 to be mounted thereon so as to be able to translate up and down.
