The embodiment of the invention provides a wall-mounted air conditioner indoor unit.

As shown in fig. 1 to 9, a wall-mounted air conditioning indoor unit according to an embodiment of the present invention may generally include a cabinet 10 and a hood panel 20.

An air outlet 12 is formed at a lower portion of the front side of the casing 10 for discharging the air flow in the casing 10 into 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 guided by the inner surface of the air guide cover plate 20 and then 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.

The air guide hood plate 20 has a partition 23 protruding from the inner surface thereof toward the outer circumferential surface of the casing 10 to partition the air guide passage 21 into an upper passage 212 having an upward opening and a lower passage 214 having a downward opening. The hood 20 is mounted on the housing 10 to be movable up and down to a down-blowing position where the lower channel 214 is opposite to the outlet 12 to guide the airflow downward, as shown in fig. 6 to 8; or to an upward blowing position where the upper duct 212 is opposed to the outlet 12 to guide the blowing air upward, as shown in fig. 1 to 4.

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.

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 to be operated, the air deflector panel 20 is moved to the down-blowing position, and the air flow is guided downward by the lower duct 214, as shown in fig. 8. When the air conditioner cooling requires the up-blowing mode, the air guide hood panel 20 is moved to the up-blowing position, 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.

As shown in fig. 5 and 9, the partition 23 has a tip 230 adjacent to 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. 9, the distance between the top edge and the bottom edge of the outlet 12 (i.e. the outlet width) is H1, and the vertical distances between the tip 230 and the top edge and the bottom edge of the wind deflector panel 20 are H2 and H3, respectively, which satisfy the following conditions: 0.5H1 ≦ H2 ≦ 0.7H1, 1.8H1 ≦ H3 ≦ 3.1H1, and for example, it is preferable to set H2 to 0.6H1, and H3 to 2.5H 1. Thus, in the up-blowing mode, the top edge of the air guiding cover plate 20 is lower than the top edge of the air outlet 12, so that the airflow at the lower part of the air outlet 12 is guided upwards by the air guiding cover plate 20, the airflow at the upper part of the air outlet 12 is directly blown forwards, the two airflows converge to cause the airflow to slightly deflect forwards, and the air blowing distance is further, as shown in fig. 4. When the air guide cover plate 20 is in the down-blowing mode, the bottom edge of the air guide cover plate is lower than that of the air outlet 12, and the air guide distance is longer, so that hot air can be better guided to blow downwards vertically, and the foot warming experience can be fully realized. In this embodiment, on the premise that the total height of the wind deflector 20 is not changed, the guiding distance of the hot wind is increased in the down-blowing mode, which is beneficial to the down-blowing of the hot wind, and the distance of the front surface of the housing below the air outlet 12 is short.

Referring to fig. 5 and 9, the upper surface of the partition 23 may be an upper arc surface 231 starting from the tip 230, extending forward and gradually inclined upward. Likewise, the lower surface of the partition 23 is a lower arc surface 232 starting from the tip 230, extending forward and gradually sloping downward. The tip 230 should be narrow, and preferably, the width H4 is less than or equal to 2mm, so as to avoid occupying more width and reducing the effective wind guiding distance of the wind guiding cover plate 20.

The radii of the upper arc 231 and the lower arc 232 are set to R1 and R2, respectively, and satisfy 1.1H1 ≦ R1 ≦ 1.3H1, and 1.1H1 ≦ R2 ≦ 1.3H1, and preferably, R1 ═ R2 ═ 1.2H 1. The air supply airflow blown forward can complete the wind direction change more smoothly and mildly under the guidance of the cambered surface, the air supply airflow is gradually changed from being blown forward to being blown upward or downward, and the wind loss and the noise are lower. The numerical ranges of R1 and R2 are determined according to the width of the air outlet, so that the conversion speed of the air supply flow is more reasonable, the phenomenon that the turning is too slow due to too large radius of the arc surface is avoided, and the phenomenon that the turning is not moderate due to too small radius of the arc surface is further avoided, so that the wind loss is increased. Further, the tangent c1 at the rear end point of the upper arc surface 231 may be inclined upward from rear to front, and the tangent c2 at the rear end point of the lower arc surface 232 may be inclined downward from rear to front, so as to properly accelerate the air flow turning process.

Referring to fig. 9, the top edge of the upper arc surface 231 may be made to constitute the top edge of the inner side surface of the wind deflector panel 20, and the inner side surface of the wind deflector panel 20 further includes a vertical surface 233 vertically extending downward from the bottom edge of the lower arc surface 232 to the bottom edge of the inner side surface of the wind deflector panel 20. That is, in the up-blowing mode, the air flow is guided only by the upper arc surface 231, and in the down-blowing mode, the air flow is guided to be turned by the lower arc surface 232 and then is guided by the vertical surface 233 to be blown out vertically and downward better.

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.

Referring to fig. 1 to 3, the wind deflector 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. 10 is a schematic exploded view of the wall-mounted air conditioning indoor unit shown in fig. 1; fig. 11 is another perspective view of the wall-mounted indoor unit of an air conditioner shown in fig. 1; FIG. 12 is a schematic view of the engagement of the end cap with the rack and pinion mechanism; fig. 13 is a schematic exploded view of the structure shown in fig. 12.

As shown in fig. 10 to 13, a rack and pinion mechanism is disposed on at least one end cover 106 of the casing 10 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. 12 to 13, 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. 10 shows a more specific structure of a wall-mounted type air conditioning indoor unit. As shown in fig. 10, 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 configuration of the cabinet itself and the structure and form of each member inside the cabinet. Namely, the wall-mounted air conditioner indoor unit can also selectively adopt other forms of heat exchangers, fans and air ducts.
