Description

Wall-mounted air conditioner indoor unit

Technical Field

The invention relates to the technical field of air conditioning, in particular to a wall-mounted air conditioner indoor unit.

Background

The cold air density tends to sink relatively more and the hot air density tends to rise relatively less. Therefore, the air conditioner needs to blow cold air upward as much as possible during cooling, and needs to blow hot air toward the ground as much as possible during heating, so that the cold air or the hot air is diffused more uniformly in the indoor space, and the cooling and heating speed is higher.

An existing wall-mounted air conditioner indoor unit is generally provided with a forward air outlet, and air guide structures such as an air guide plate and a swing blade are utilized to guide the air outlet direction of air supply airflow so as to realize upward air blowing or downward air blowing. However, the current wind guide structures have limited wind guide angles, and can only supply wind obliquely upwards or obliquely downwards, so that cold wind or hot wind hardly reaches the roof or the ground, and the refrigerating or heating effect is influenced.

and the outer cover plate is arranged on the outer side of the air guide cover plate and is fixed on the machine shell, so that the air guide cover plate is hidden on the inner side of the outer cover plate when being positioned at the upward blowing position and the downward blowing position.

Optionally, the air deflector cover plate and the outer cover plate are both vertically arranged plate-shaped as a whole, and the air deflector cover plate is superposed on the inner side of the outer cover plate.

Optionally, a bottom end of the exterior cover plate is lower than a bottom end of the cabinet.

Optionally, the partition has a tip adjacent to the outer peripheral surface of the housing; the upper surface of the partition part is an inwards concave cambered surface which starts from the tip end, extends in the direction away from the shell, gradually inclines upwards and is tangent to the inner side surface of the rest part of the air guide cover plate; and the lower surface of the partition part is an inwards concave cambered surface which starts from the tip end, extends towards the direction far away from the shell, gradually inclines downwards and is tangent to the inner side surface of the rest part of the air guide cover plate.

Optionally, the air deflector plate is further configured to be movable to a position where the partition portion is located in the middle of the air outlet, so as to guide part of the supply air flow by each of the lower duct and the upper duct.

Optionally, the air outlet is arranged on the front surface of the casing; the air guide cover plate comprises a front section positioned in front of the air outlet and two bending sections which respectively extend backwards from the two transverse ends of the front section, and the two bending sections are respectively arranged on the end covers at the two transverse sides of the machine shell; the outer cover plate comprises a front plate section opposite to the front section and two bent plate sections opposite to the two bent sections, and the two bent plate sections are fixedly installed on the two end covers respectively.

Optionally, a rack and pinion mechanism is arranged on at least one end cover of the housing, and is used for driving the air guide cover plate to move up and down, and the rack and pinion mechanism comprises a motor, a gear and a rack which are meshed with each other; the motor set up in the end cover is inboard, the gear install in the motor, the rack can set up with translation from top to bottom in the end cover is inboard, and its part passes through the vertical rectangular hole of stepping down that the end cover was seted up stretches out to the end cover outside, and with the wind-guiding cover plate is connected.

Optionally, a ratio of a distance from the lower edge of the air outlet to the bottom end of the front surface of the housing to the width of the air outlet is greater than 1/2.

In the wall-mounted air conditioner indoor unit, the air guide cover plate is arranged on the outer side of the shell in a translation mode and defines 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 blow molding mode for selection, and the refrigeration and heating effects are improved. For example, when the air conditioning heat needs to blow the air flow downward, the air guiding cover plate may be moved to the downward blowing position, and the air flow (e.g., cold air, hot air, fresh air, or purified air flow) is guided by the lower channel to flow downward along the outer peripheral surface of the casing. After the air flow flows out of the lower channel, the air flow continues to flow downwards along the outer peripheral surface of the shell by means of the wall attachment effect so as to smoothly reach the ground, and a carpet type air supply effect is formed. Similarly, when the air conditioner cooling operation is in the up-blowing mode, the air guide cover plate is moved to the up-blowing position, the air supply airflow is guided by the upper channel to flow upwards along the outer periphery of the shell tightly, and after flowing out of the upper channel, the air supply airflow continues to flow upwards along the outer periphery of the shell by virtue of the wall attachment effect so as to smoothly reach the roof.

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.

Furthermore, the wall-mounted air conditioner indoor unit of the invention enables the front surface of the casing to be a vertical surface, so that the air flow of the air supply can form a wall attachment effect on the front surface of the casing, and the air flow can flow upwards or downwards along the front surface of the casing better. In addition, the ratio of the distance between the lower edge of the air outlet and the bottom end of the front surface of the machine shell to the width of the air outlet is larger than 1/2, so that the front surface of the machine shell below the air outlet has enough height, and when the air conditioner runs in a downward blowing mode, the lower channel is longer, the wall attachment effect is more favorably formed, and the air supply airflow is better guided to the right lower side.

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

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 cabinet 10, a louver 20, and an outer louver 90.

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, or 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 deflection cover plate 20 is translatably installed to the casing 10, and defines an upper passage 212 opened upward and a lower passage 214 opened downward together with the outer circumferential surface of the casing 10. That is, the air guide hood panel 20 is parallel or nearly parallel to the outer peripheral surface of the casing 10, and a space between the two constitutes an upper duct 212 and a lower duct 214. The wind deflector panel 20 is configured to: the lower channel 214 can be moved to a downward blowing position for communicating with the air outlet 12 so as to guide the air flow downward; or to an upward blowing position where the upper duct 212 communicates with the outlet 12 to guide the flow of the blast air upward.

After being blown out from the outlet 12 of the casing 10, the blowing air flow is blocked by the inner wall of the air guide cover plate 20, and cannot be directly blown out horizontally, but is blown out upward or downward along the outer periphery of the casing 10. Because the air flow flows upwards or downwards along the periphery of the casing 10, a wall attachment effect (also called an attachment effect) can be formed, so that the air flow can smoothly reach the roof or the ground along the periphery 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.

Specifically, fig. 1 to 5 show the blowing air flow blowing upward, and fig. 6 to 8 show the blowing air flow blowing downward. When the air conditioner cooling operation is in the up-blowing mode, the air guide cover plate 20 is moved to the up-blowing position, as shown in fig. 1 to 5, the upper channel 212 guides the supply air flow to flow upwards along the outer peripheral surface of the casing 10, and after the supply air flow flows out of the upper channel 212, the supply air flow continues to flow upwards along the outer peripheral surface of the casing 10 by virtue of the coanda effect, so as to smoothly reach the roof. When the air conditioning heat needs to blow the air flow downward, the air guiding cover plate 20 may be moved to the downward blowing position, as shown in fig. 6 to 8, so that the air flow is guided by the lower channel 214 to flow downward along the outer peripheral surface of the casing 10, and after flowing out of the lower channel 214, the air flow continues to flow downward along the outer peripheral surface of the casing 10 by virtue of the coanda effect, so as to smoothly reach the ground, thereby forming a carpet type air blowing effect.

The area of the outer peripheral surface of the casing 10 through which the air flow flows can be a flat surface, so that the air flow can better adhere to the outer peripheral surface of the casing 10 to flow. 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.

As shown in fig. 1 to 8, the outer cover plate 90 is disposed outside the wind deflector plate 20 and fixed to the cabinet 10 such that the wind deflector plate 20 is hidden inside the outer cover plate 90 in both the up-blowing position and the down-blowing position. That is, the upper end of the outer cover plate 90 is higher than or at least flush with the upper end of the air deflector plate 20 at any position of the air deflector plate 20; the lower ends of the outer shroud panels 90 are all below or at least flush with the lower end of the air deflection shroud panel 20. Therefore, the position and the moving process of the air guide hood plate 20 are invisible, and the fixed outer hood plate 90 plays a role in decoration so as to keep the stability of the appearance of the wall-mounted air conditioner indoor unit. The top of the exterior cover plate 90 is higher than the top end of the air guide cover plate 20, and the bottom thereof is lower than the bottom end of the air guide cover plate 20.

In some embodiments, referring to fig. 4 and 8, the wind deflector plate 20 and the outer cover plate 90 may be both vertically disposed plates as a whole, and the wind deflector plate 20 is stacked on the inner side of the outer cover plate 90. Specifically, the outer surface of the air deflection cover plate 20 may be attached to the inner surface of the outer cover plate 90, or may be spaced apart by a small distance, for example, 1cm or less. The bottom end of the exterior cover plate 90 may be lower than the bottom end of the casing 10, so that the air is better guided to flow downwards by the inner surface of the exterior cover plate 90 in the down-blowing mode, and the defect of a shorter guiding distance (de) of the front surface of the casing below the air outlet 12 is overcome.

In some embodiments, the air guide cover plate 20 may be mounted on the casing 10 to be vertically translatable, and has a partition portion 23 protruding from an inner surface thereof toward an outer circumferential surface of the casing 10 to partition the upper passage 212 and the lower passage 214. That is, the partition 23 partitions the annular space defined between the air guide cover plate 20 and the outer surface of the casing 10 into upper and lower portions, i.e., an upper duct 212 and a lower duct 214. When the air guiding hood plate 20 is in the upward blowing position, the partition portion 23 is located below the air outlet 12, as shown in fig. 1 to 5, so that the upper channel 212 is communicated with the air outlet 12; when the air guide hood plate 20 is in the downward blowing position, the partition portion 23 is located above the air outlet 12, so that the lower channel 214 is communicated with the air outlet 12, as shown in fig. 6 to 8. Of course, the air guide cover plate 20 may be configured to be movable to a position (not shown) where the partition 23 is located in the middle of the outlet 12 (i.e., a position between fig. 4 and 8) to guide a part of the blowing air flow from each of the lower duct 214 and the upper duct 212, so that the wall-mounted air conditioning indoor unit can blow air in both the upper and lower directions at the same time, thereby increasing 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 an inward 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 can enter the guide range of the partition 23 smoothly 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 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.

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 106 on 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.

In addition, in order to match the outer shape of the wind deflector panel 20 to sufficiently cover the wind deflector panel 20, the outer panel 90 includes a front plate section 901 and two bending plate sections 902. The front plate segment 901 faces the front section 201 of the air deflection cover plate 20, and the two bent plate segments 902 respectively face the two bent sections 202 of the air deflection cover plate 20. The two bent plate sections 902 are fixedly mounted to the two end caps 106, respectively. For example, each buckle plate segment 902 may be provided with a projection toward the end cap 106, to be fixed to the end cap 106 by screws or other means, and the detailed structure is not described.

Fig. 9 is a schematic exploded view of the wall-mounted air conditioning indoor unit of fig. 1; fig. 10 is a schematic view of the wall-mounted air conditioning indoor unit of fig. 1 from another perspective with the outer cover plate hidden; FIG. 11 is a schematic view of the engagement of the end cap with the rack and pinion mechanism; 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 gear 73 in the width direction, and each sliding groove 731 is matched with one sliding rail 1071 to allow the rack gear 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 sucked into the air duct 40 by the cross-flow fan 50, and flows to the air outlet 12.

Fig. 9 shows a more specific structure of a 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 casing 10. A motor 51 is installed at 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.
