As shown in fig. 1 to 8, a wall-mounted air conditioning indoor unit according to an embodiment of the present invention may generally include a casing 10 and a wind deflector panel 20.

The casing 10 is provided with an air outlet 12 for discharging the air flow from the casing 10 to the room. The air supply flow can be cold air produced by the wall-mounted air conditioner indoor unit in a refrigeration mode, hot air produced in a heating mode, fresh air introduced in a fresh air mode, purified air produced in a purification mode and the like. The cabinet 10 may be a transversely extending elongated structure as a whole.

The air guide hood plate 20 is disposed outside the air outlet 12 to define an air guide passage 21 with an outer circumferential surface of the cabinet 10. That is, the air guide cover plate 20 is parallel or nearly parallel to the outer peripheral surface of the casing 10, and a space between the two forms the air guide passage 21. The air guide passage 21 is used to guide the air flow flowing out from the air outlet 12 to flow upward and/or downward along the outer circumferential surface of the casing 10. That is, after the airflow (for example, cold air, hot air, fresh air, or purified air) is blown out from the outlet 12 of the casing 10, the airflow is blocked by the inner wall of the air guide cover plate 20, and cannot be blown out directly horizontally, but is blown out upward and/or downward along the outer circumferential surface of the casing 10. The upward and/or downward blowing here means: the blowing air flow can be blown out only upwards, or only downwards, or both upwards and downwards. Fig. 1 to 5 show the blowing air flow blowing upward, fig. 6 to 8 show the blowing air flow blowing downward, and fig. 13 shows the blowing air flow blowing upward simultaneously.

Because the air current of supply air is close to the peripheral face of the casing 10 and flows upwards or downwards, the wall attachment effect (also called attachment effect) can be formed, thereby the air current can smoothly reach the roof or the ground along the peripheral face of the casing 10, and the cooling or heating effect of the wall-mounted air conditioner indoor unit is better. Meanwhile, the discomfort of the human body caused by cold air or hot air blowing can be avoided.

In some embodiments, the area of the outer peripheral surface of the casing 10 through which the supply airflow flows may be a flat surface, so as to facilitate the supply airflow to better fit the outer peripheral surface of the casing 10. For example, as shown in fig. 1, in the case where the air outlet 12 is opened at 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, may be a flat surface.

In some embodiments, as shown in fig. 1 and 8, the air deflection cover plate 20 may be mounted to the cabinet 10 to be movable up and down in a translational manner. In this case, the air guide cover plate 20 is a vertical plate. The air guide hood panel 20 has a partition 23 projecting from the inner surface thereof toward the outer peripheral surface of the casing 10. The partition 23 is used to partition the air guide passage 21 into an upper passage 212 opening upward and a lower passage 214 opening downward. The wind deflector panel 20 is configured to: the partition 23 can be moved to a position above the outlet 12 to guide the air flow downward through the lower channel 214, as shown in fig. 6 to 8; or to a position where the partition 23 is located below the outlet 12, so as to guide the blowing air upward through the upper duct 212, as shown in fig. 1 to 4.

Therefore, the wall-mounted air conditioner indoor unit has an upper blowing mode and a lower blowing mode for selection, and the refrigeration and heating effects are obviously improved. For example, when the air conditioning heat requires the down blowing mode, the air guide hood panel 20 is moved to a position where the partition 23 is located above the outlet 12, and the air flow is guided downward by the lower duct 214, as shown in fig. 8. When the air conditioner cooling needs to operate the upward blowing mode, the air guide hood plate 20 is moved to a position where the partition portion 23 is located below the air outlet 12, and the air flow is guided upward by the upper duct 212, as shown in fig. 4. Of course, the air guide hood panel 20 may be configured to be movable to a position (not shown), where the partition 23 is located at the middle of the outlet 12 in the vertical direction (i.e., at a position between fig. 4 and 8), so as to guide a part of the supplied air flow from each of the lower duct 214 and the upper duct 212, so that the wall-mounted air conditioning indoor unit supplies air in two directions, i.e., up and down, at the same time, so as to increase the air conditioning speed.

In some embodiments, as shown in fig. 4 and 5, the partition 23 has a tip 230 adjacent to the outer circumferential surface of the casing 10. The tip 230 is adjacent to the outer circumferential surface of the casing 10, and can be made to fit with the outer circumferential surface of the casing 10. When the air guide cover plate 20 is at the upward blowing position, the sealing performance between the partition part 23 and the outer peripheral surface of the casing 10 is better, and the downward leakage of the air flow is avoided; when the air guide hood plate 20 is at the down-blowing position, the sealing performance between the partition portion 23 and the outer peripheral surface of the casing 10 is improved, 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 cowl panel 20 moves up and down, the tip 230 may rub against the outer surface of the casing 10 to generate a loud noise. To avoid this noise, the tip 230 may be spaced from the outer surface of the casing 10.

Referring to fig. 4 and 5, the upper surface 231 of the partition 23 is an inward concave curved surface starting from the tip 230, extending in a direction away from the casing 10 (in the embodiment shown, forward), and gradually inclining upward, and being tangent to the inner side surface of the rest of the wind deflector plate 20. Similarly, the lower surface 232 of the partition 23 is a concave arc surface starting from the tip 230, extending in a direction away from the casing 10 and gradually inclining downwards, and tangent to the inner side surface of the rest of the air guide hood plate 20. In this way, when the blowing air flow is blown out from the outlet 12 and then turns upward or downward, the blowing air flow gradually turns along the upper surface or the lower surface of the partition 23, and the process is more gentle, and the wind loss and the noise are less.

When the air guide hood panel 20 is in the upper blow-molding mode, the tip 230 of the partition portion 23 may be positioned opposite to the lower edge of the air outlet 12, so that the upper surface 231 of the partition portion 23 is connected to the lower wall of the air duct 40, referring to fig. 4. Moreover, since the upper surface 231 of the partition 23 is a concave arc surface, the upper surface 231 corresponds to an extension of the lower wall of the air duct 40, so that the air flow flowing out of the air duct 40 enters the guiding range of the partition 23 smoothly and with low resistance.

Similarly, when the wind deflector panel 20 is in the down-blowing mode, the tip 230 of the partition 23 may be opposite to the upper edge of the outlet 12, so that the lower surface 232 of the partition 23 is in contact with the upper wall of the wind tunnel 40, as shown in fig. 8. Since the lower surface 232 of the partition portion 23 is a concave arc surface, the lower surface 232 is equivalent to an extension of the upper wall of the air duct 40, so that the air flow flowing out of the air duct 40 smoothly enters the guiding range of the partition portion 23 with low resistance.

In some embodiments, as shown in fig. 1 to 8, the front surface of the casing 10 may be a vertical surface (a part of the front surface of the casing 10, that is, the outer peripheral surface of the casing 10) as a whole, and specifically may be a vertical plane or a curved surface such as an arc surface whose axis extends vertically. The outlet 12 may be opened at a lower portion of the front surface of the cabinet 10. The outlet 12 may be more specifically an elongated shape having a length direction parallel to the transverse direction of the cabinet 10.

Referring to fig. 5, the ratio of the distance (de) from the lower edge d of the outlet 12 to the bottom e of the front surface of the housing 10 to the width (cd) of the outlet 12 is greater than 1/2, i.e. de/cd > 1/2, preferably greater than 3/4. Thus, when the wall-mounted air conditioner indoor unit operates in the down-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 air flow to flow downwards, thereby improving the wall attachment effect. In addition, the distance from the separating portion 23 to the bottom end of the wind guide cover plate 20 may be greater than the distance from the separating portion 23 to the top end of the wind guide cover plate 20 (specifically, the tip 230 of the separating portion 23 may be used as a measurement reference), that is, the separating portion 23 is located on the upper portion of the wind guide cover plate 20, so as to better guide the air to flow downwards and blow in the downward blowing mode, and make up for the defect that the guiding distance (i.e., de) of the front surface of the chassis on the lower side of the air outlet 12 is short.

Referring to fig. 1 to 3, for the solution that the air outlet 12 is opened on the front surface of the casing 10, the air guiding cover plate 20 may include a front section 201 and two bending sections 202. The front section 201 is located in front of the air outlet 12, and is mainly used for guiding the air flow. Two bent sections 202 extend rearward from both lateral ends of the front section 201 to be mounted to the end caps of both lateral sides of the casing 10, respectively. In this embodiment, the wind deflector 20 is connected to the transverse end cover 106 of the casing 10 through the two bent sections 202, so that the front side of the wind deflector 20 has a more complete appearance, and a driving mechanism does not need to be disposed on the front side of the casing 10 to occupy an air outlet space. Moreover, each bent section 202 is provided with a wind shield 2021 extending towards the end cover 106 for blocking the backward flow of the supply air flow, so that the supply air flow can better flow upwards or downwards, and the backward flow diffusion can be prevented from affecting the upward and downward wind force.

fig. 12 is a schematic exploded view of the structure shown in fig. 11.

As shown in fig. 9 to 12, at least one end cover of the casing 10 is provided with a rack and pinion mechanism for driving the wind deflector plate 20 to move up and down, so as to switch between the up-blowing position and the down-blowing position. Preferably, a rack and pinion mechanism is disposed on each of the two end caps 106 to drive the two transverse ends of the wind deflector plate 20 to move up or down synchronously, so that the movement is more stable and smooth.

Each of the rack and pinion mechanisms includes a motor 71, a pinion 72 and a rack 73 that mesh with each other. The motor 71 is disposed inside the end cap 106. The gear 72 is mounted on the motor 71, the rack 73 is disposed inside the end cover 106 in a vertically movable manner, and a portion of the rack extends out of the end cover 106 through a long vertical offset hole 1061 formed in the end cover 106 so as to be connected to the wind deflector plate 20. When the motor 71 drives the gear 72 to rotate, the gear 72 drives the rack 73 to move up and down, so as to drive the air guide hood panel 20 to move up and down.

Specifically, as shown in fig. 11 to 12, a mounting member 107 may be fixed to an inner wall of the end cap 106. The mounting member 107 is screwed to a plurality of mounting portions 1062 provided on an inner wall of the end cap 106 via a plurality of mounting portions 1072 provided thereon. The mounting 107 is formed with two spaced and vertically extending slide rails 1071. Two sliding grooves 731 having opposite opening directions are formed at both ends of the rack 73 in the width direction, and each sliding groove 731 is matched with one sliding rail 1071 to allow the rack 73 to slide up and down along the mounting member 107. That is, the mount 107 functions to form a slide rail 1071 on which the rack gear 73 is mounted so as to be movable in translation up and down.

A bracket 108 is also secured to the inner wall of the end cap 106 for mounting the motor 71. The rack 73 is sandwiched between the gear 72 and the mount 107, or the gear 72 is located on the side of the mount 107 facing away from the inner wall of the end cap 106. The side of the rack 73 facing the gear 72 is formed with teeth to engage with the gear 72, and a rib 732 is formed to protrude outward from the side facing the end cap 106, and the rib 732 extends out of the end cap 106 through the vertical strip relief hole 1061 and is connected to the air guide cover plate 20, for example, by a screw. Specifically, the convex strip 732 may be connected to the wind blocking portion 2021. Thus, the wind blocking portion 2021 is used for connecting the protruding strips 732 and blocking the airflow, and the design is very ingenious.

In this embodiment, the mounting member 107 and the bracket 108 are provided on the inner wall of the end cover 106, so that the main structure of the rack and pinion mechanism is mounted inside the end cover 106, which does not affect the appearance of the wall-mounted air conditioning indoor unit. And the air guide cover plate 20 positioned outside the end cover 106 is connected by arranging the vertical strip abdicating hole 1061 on the end cover 106, so that the design is very simple and reasonable.

As shown in fig. 4, the top of the casing 10 is provided with an air inlet 11, an air duct 40 is disposed inside the casing 10, and an outlet of the air duct 40 is communicated with the air outlet 12. A cross-flow fan 50 having an axis extending in a lateral direction is provided at an inlet of the air duct 40. The three-stage heat exchanger 30 surrounds the crossflow blower 50. When the wall-mounted air conditioner indoor unit operates in a cooling mode or a heating mode, indoor air enters the interior of the casing 10 through the air inlet 11, exchanges heat with the three-section heat exchanger 30, is finally sucked into the air duct 40 by the cross-flow fan 50, and flows towards the air outlet 12.

Fig. 9 shows a more specific structure of the wall-mounted type air conditioning indoor unit. As shown in fig. 9, the casing 10 includes a front panel 101, a front lower panel 102, a bottom plate 103, a cover 104, a skeleton 105, and two end caps 106. The front panel 101 and the front lower panel 102 are connected to form the front part of the casing 10, and the outlet 12 is opened in the region where they are connected. The bottom plate 103 constitutes the bottom of the cabinet 10. The casing 104 and the frame 105 are disposed at the rear side of the front panel 101 to form the air inlet 11 and the air duct 40. The two end caps 106 constitute both lateral end portions of the cabinet 10. A motor 51 is mounted to an end of the crossflow blower 50 to drive the crossflow blower 50 to rotate. The motor 51 is mounted on a motor mount 52. An electric cabinet 53 is arranged on one side of the motor base 52 in the transverse direction. The air outlet 12 is provided with a swing blade assembly 60 to adjust the left and right air outlet directions of the air outlet 12. Sensor 80 is installed to horizontal one side top of bottom plate 103 to be used for detecting the indoor condition, thereby according to the indoor condition (detect temperature, human condition etc.), thereby carry out intelligent control to empty regulation control parameter (wind speed, wind direction, temperature etc.).

Of course, the present invention is not limited to the structure of the casing itself and the structure and form of each member inside the casing. Namely, the wall-mounted air conditioner indoor unit can also selectively adopt other forms of heat exchangers, fans and air ducts.

Fig. 13 is a schematic cross-sectional view of a wall-mounted air conditioning indoor unit according to another embodiment of the present invention.

As shown in fig. 13, the difference between this embodiment and the embodiment shown in fig. 1 to 12 is that in this embodiment, the wind deflector 20 is fixedly installed on the casing 10, and the partition 23 is located at the middle position of the vertical direction of the air outlet 12, so that both the lower duct 214 and the upper duct 212 are communicated with the air outlet 12, and the air flow is guided by the lower duct 214 and the upper duct 212, so that the wall-mounted air conditioning indoor unit can simultaneously blow air in both the upper and lower directions, thereby increasing the air conditioning speed.

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.
