In the wall-mounted air conditioner indoor unit, the air guide cover plate is arranged outside the casing, and an air guide channel is defined by the air guide cover plate and the outer peripheral surface of the casing. After being blown out from the air outlet of the casing, the supply air flow (such as cold air, hot air, fresh air or purified air flow) inside the casing is blocked by the air guide cover plate, and cannot be directly and horizontally blown out, but is blown out upwards and/or downwards along the outer peripheral surface of the casing. Because the air supply flow flows along the periphery of the casing, a wall attachment effect is formed, and the air supply flow can smoothly reach the roof or the ground along the periphery of the casing, so that the wall-mounted air conditioner indoor unit has better refrigerating or heating effect. Meanwhile, the discomfort of human body caused by cold air or hot air blowing can be avoided.

In addition, in the wall-mounted air conditioner indoor unit, the distance between the air guide cover plate and the outer peripheral surface of the casing is adjustable. When the distance is increased, the air outlet section of the air guide channel is enlarged, air is more smoothly discharged, and the air outlet quantity is larger; when the distance is adjusted to be small, the air outlet section of the air guide channel is reduced, and the air outlet volume is reduced.

Furthermore, in the wall-mounted air conditioner indoor unit, the air guide cover plate moves vertically relative to the machine shell, and the partition part divides the air guide channel into an upper channel with an upward opening and a lower channel with a downward opening, so that the wall-mounted air conditioner indoor unit has an upward blowing mode and a downward blowing mode for selection, and the refrigeration and heating effects are improved. For example, when the air conditioning heat needs to operate in the down-blowing mode, the air guide cover plate is moved to a position where the partition part is located above the air outlet, and the air flow is guided downwards by the lower channel. When the air conditioning needs to run in an upward blowing mode, the air guide cover plate is moved to a position where the separation part is positioned below the air outlet, and the air supply flow is guided upwards by the upper channel, so that the air conditioning device is simple in structure and convenient to adjust.

Furthermore, in the wall-mounted air conditioner indoor unit, the upper surface and the lower surface of the partition part are both concave cambered surfaces, so that the direction change is more moderate when the air supply flow is blown out from the air outlet and then turns upwards or downwards, and the wind power loss and the noise are reduced.

The embodiment of the invention provides a wall-mounted air conditioner indoor unit. An indoor unit of a wall-mounted type air conditioner is an indoor part of a split wall-mounted type room air conditioner for conditioning indoor air, such as cooling/heating, dehumidifying, introducing fresh air, and the like.

Fig. 1 is a schematic structural view of a wall-mounted type air conditioning indoor unit according to an embodiment of the present invention; fig. 2 is a schematic front view of the wall-mounted air conditioning indoor unit of fig. 1; fig. 3 is a schematic plan view of the wall-mounted air conditioning indoor unit shown in fig. 1; FIG. 4 is a cross-sectional view M-M of FIG. 2; FIG. 5 is an enlarged view at A of FIG. 4; fig. 6 is a schematic view showing the wall-mounted air conditioning indoor unit shown in fig. 1 in a state where the air guide plate is moved forward and backward.

As shown in fig. 1 to 6, a wall-mounted air conditioning indoor unit according to an embodiment of the present invention may generally include a cabinet 10, two installation bases 90, and a hood panel 20.

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

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

The air guiding plate 20 includes a front section 201 extending transversely in front of the outlet 12 and two bent sections 202 extending rearward from both ends of the front section 201. The rear end of each bent section 202 is mounted to a mounting base 90 to be movable forward and backward. The air guide hood plate 20 and the outer circumferential surface of the casing 10 define an air guide passage 21. 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, and fig. 6 to 8 show the blowing air flow blowing downward.

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.

Since the bent section 202 of the air guiding cover plate 20 is mounted on the mounting base 90 in a manner of being capable of moving forward and backward, the whole air guiding cover plate 20 can move forward and backward, so that the width of the air guiding channel 21 (i.e. the distance between the air guiding cover plate 20 and the outer circumferential surface of the casing 10, which is marked as B in fig. 5) can be changed as required, so as to adjust the air output of the air guiding channel 21.

Specifically, after the distance B is increased, the air outlet cross section of the air guide channel 21 is increased, so that the air outlet is smoother, and the air outlet volume is larger, as shown in fig. 6, where B1 is greater than B in fig. 6. When the distance B is reduced, the air outlet section of the air guiding channel 21 is reduced, and the air outlet volume is reduced, as shown in fig. 1 to 5. The embodiment of the invention realizes the adjustment of the air output by adjusting the position of the air guide cover plate 20, and meets the adjustment requirements of different use working conditions or scenes on the air output.

Fig. 7 is a schematic view of the wall-mounted air conditioning indoor unit of fig. 1 switched to a down-blowing mode; fig. 8 is a schematic front view of the wall-mounted air conditioning indoor unit of fig. 7; fig. 9 is a cross-sectional view N-N of fig. 8.

In some embodiments, as shown in fig. 1 to 9, two of the mounting bases 90 may be mounted to the end cover 106 to be movable up and down, so that the air deflection cover plate 20 may be movable up and down with the two mounting bases 90. The air guide cover plate 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: can 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 air flow downward through the lower channel 214, as shown in fig. 7 to 9; or move with the mounting seat 90 to a position where the partition 23 is located below the air outlet 12, so as to guide the air flow upward through the upper channel 212, as shown in fig. 1 to 6.

Therefore, the wall-mounted air conditioner indoor unit has an upward blowing mode and a downward blowing mode for a system or a user to select, so that 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. 9. When the air conditioner cooling mode needs to be operated in the up-blowing mode, the air guide cover plate 20 is moved to a position where the partition portion 23 is located below the outlet 12, and the air flow is guided upward by the upper duct 212, as shown in fig. 4.

Of course, the air guide plate 20 may be moved to a position between the upper blowing mode and the lower blowing mode, so that both the upper duct 212 and the lower duct 214 communicate with the outlet 12, and a part of the blowing air flow flowing out of the outlet 12 is guided upward by the upper duct 212 and the other part is guided downward by the lower duct 214, so as to simultaneously blow air upward and downward, thereby increasing the air conditioning speed.

As shown in fig. 1 and 12, each bent section 202 may have a wind shielding portion 2021 extending toward the end cover 106, and the inner side of the wind shielding portion 2021 abuts against the outer wall of the end cover 106 to block the backward flow of the supply air flow, so that the supply air flow can better flow upward or downward, and the backward flow can be prevented from spreading to affect the upward and downward wind forces.

In some embodiments, referring to fig. 4 and 5, the partition 23 has a tip 230 adjacent to the outer peripheral 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 air flow is avoided; when the air guide hood plate 20 is in the downward blowing position, the partition 23 and the outer peripheral surface of the casing 10 are better sealed to prevent the upward leakage of the air flow. Of course, if the tip 230 is too close to the outer surface of the casing 10, when the wind deflector plate 20 moves up and down, the tip 230 and the outer surface of the casing 10 rub against each other, which may 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 inwardly concave curved surface starting from the tip 230, extending away from the casing 10 and gradually inclining upwards, and tangent to the inner side surface of the rest of the air guiding hood plate 20. Similarly, the lower surface 232 of the partition 23 is a concave arc surface starting from the tip 230, extending away from the casing 10 and gradually inclining downwards, and tangent to the inner side surface of the rest of the air guide cover 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. 9. 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 9, 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 air outlet 12 may be opened on the front surface of the casing 10, specifically, on the lower portion of the front surface of the casing 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 air outlet 12 to the bottom e of the front surface of the housing 10 to the width (cd) of the air 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 between the separating portion 23 and the bottom end of the air guide cover plate 20 may be greater than the distance between the separating portion 23 and the top end of the air 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 air 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.

Fig. 10 is a schematic exploded view of the wall-mounted air conditioning indoor unit of fig. 1; fig. 11 is an enlarged view of fig. 10 at B.

As shown in fig. 10 and 11, in some embodiments, the mount 90 is connected to the wind deflector plate 20 through a rack and pinion mechanism to drive the wind deflector plate 20 to translate back and forth.

Specifically, a first rack 76 extends rearward from a rear end of each bending section 202, a first motor 74 and a first gear 75 disposed on the first motor 74 are mounted on each mounting seat 90, and each first gear 75 is engaged with the first rack 76 to drive the bending sections 202 to move back and forth.

Each of the mounts 90 defines a forwardly opening mounting cavity 910, and the first motor 74 and the first gear 75 are disposed within the mounting cavity 910 with the first rack 76 extending therethrough through the front opening of the mounting cavity 910 to engage the first gear 75. The mounting seat 90 specifically includes a box 91 and a cover 92, the box 91 is provided with the aforementioned mounting cavity 910, an opening is formed on a side surface of the box 91 so as to mount the first motor 74 and the first gear 75, and the cover 92 is used for covering the opening of the box 91.

Fig. 12 is another perspective view of the wall-mounted indoor unit of an air conditioner shown in fig. 1; FIG. 13 is a schematic view of the mating of the end cap with the second rack gear mechanism; fig. 14 is a schematic exploded view of the structure shown in fig. 13.

As shown in fig. 12 to 14, a second rack and pinion mechanism is disposed on each of the two end caps 106 of the casing 10, and is used for driving the mounting seat 90 to move up and down, so as to switch between the up-blowing position and the down-blowing position.

Each second gear rack mechanism comprises a second motor 71, a second gear 72 and a second gear rack 73 which are meshed with each other. The second motor 71 is disposed inside the end cap 106. The second gear 72 is mounted on the second motor 71, the second rack 73 is disposed inside the end cover 106 in a vertically movable manner, and a portion of the second rack extends out of the end cover 106 through a vertical strip-shaped offset hole 1061 formed in the end cover 106 so as to be connected to the mounting base 90. 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 seat 90 to translate up and down.

Specifically, as shown in fig. 13 to 14, a mounting member 107 may be fixed to an inner wall of the end cap 106. The mounting member 107 is coupled by screws with a plurality of mounting portions 1072 provided thereon and a plurality of mounting portions 1062 provided on an inner wall of the end cap 106. Two slide rails 1071 are formed on the mounting member 107 and arranged at an interval and extend vertically. Two sliding grooves 731 having opposite opening directions are formed at both ends of the second rack gear 73 in the width direction, and each sliding groove 731 is matched with one sliding rail 1071 to allow the second rack gear 73 to slide up and down along the mounting part 107. That is, the mount 107 functions to form a slide rail 1071 on which the second rack 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 second motor 71. The second gear rack 73 is sandwiched between the second gear 72 and the mount 107, or the second gear 72 is located on a side of the mount 107 facing away from an inner wall of the end cap 106. The second rack 73 is toothed on a side facing the second gear 72 to engage with the second gear 72, and a rib 732 is formed to protrude outward on a side facing the cap 106, wherein the rib 732 extends out of the cap 106 through the vertical strip relief hole 1061 and is connected to the mounting seat 90, 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, and the main structure of the second rack and pinion mechanism is mounted inside the end cover 106, so that the appearance of the wall-mounted air conditioning indoor unit is not affected. And the vertical strip abdicating hole 1061 is formed in the end cover 106 to connect the mounting seat 90 positioned on the outer side of 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.
