Fig. 1 is a schematic view of an air conditioner indoor unit 20 according to one embodiment of the present utility model.

Referring to fig. 1, the present embodiment provides an air conditioner indoor unit 20, and the air conditioner indoor unit 20 includes a housing 21, an air intake baffle 22, and a supporting device 23.

The front surface of the housing 21 is provided with an air inlet. The air intake damper 22 is provided at the front side of the housing 21 and is used to open and close the air intake. The supporting means 23 is provided on the housing 21 and serves to support the air intake damper 22 and guide the air intake damper 22 to move forward and backward, thereby opening and closing the air intake.

The air inlet of the indoor unit 20 of the air conditioner is arranged on the front surface of the shell 21, the front side of the shell 21 is provided with an air inlet baffle 22 for opening and closing the air inlet, and a supporting device 23 is arranged on the shell 21 and used for supporting the air inlet baffle 22 and guiding the air inlet baffle 22 to move back and forth so as to open and close the air inlet. The air inlet baffle 22 capable of opening and closing the air inlet is arranged, so that the air conditioner indoor unit 20 can close the air inlet, and the air inlet is not exposed in the sight range of a user.

When the air inlet is opened, an air inlet gap is formed between the peripheral side of the air inlet baffle 22 and the front surface of the casing 21 of the air conditioner indoor unit 20, so that air flow can enter the air conditioner indoor unit 20 from the upper, lower, left and right edges of the air inlet baffle 22 through the air inlet gap.

In the embodiment shown in fig. 1, the air conditioner indoor unit 20 includes two sets of support devices 23 and is disposed on both lateral sides of the air conditioner indoor unit 20 to simultaneously provide support to both lateral sides of the air intake baffle 22. It will be appreciated that the support means 23 on one side of the embodiment of figure 1 is not visible due to the obstruction by the air inlet baffle 22.

In some alternative embodiments, the indoor unit 20 may also include only one set of supporting devices 23, and be disposed in a lateral middle portion of the indoor unit 20 and connected to a lateral middle portion of the air intake baffle 22. Of course, the indoor unit 20 of the air conditioner may include three or more sets of supporting devices 23, which is not limited herein.

The support device 23 guides the air intake baffle 22 to move back and forth, which means that the support device 23 guides the air intake baffle 22 to move back and forth vertically, can translate right in front of or right behind, can also move obliquely upwards or obliquely downwards, but does not guide the air intake baffle 22 to rotate, i.e. causes the air intake baffle 22 to change in inclination angle.

The supporting device 23 of this embodiment may be a transmission link composed of one or more links, or may be a mechanical arm or a mechanical rod capable of moving back and forth, such as an electric push rod or an electric screw rod.

The supporting device 23 is disposed on the housing 21, which means that the supporting device 23 may be disposed on an outer side of the housing 21, for example, on an outer surface of one or both lateral walls of the housing 21, or may be disposed on an inner side of the housing 21, for example, directly disposed on an inner surface of one or both lateral walls of the housing 21, or indirectly connected and fixed to the housing 21 through other connection structures.

Fig. 2 is a schematic perspective view of an indoor unit 20 of an air conditioner according to an embodiment of the present utility model, in which the structure of a supporting device 23 is more clearly and intuitively illustrated, and fig. 2 conceals other devices, components and structures than a casing 21, an air intake baffle 22 and the supporting device 23 of the indoor unit 20, and illustrates positions of the air intake baffle 22 and the supporting device 23 when the air intake is closed in a dotted line.

Referring to fig. 2, the supporting device 23 includes a first supporting link 231 and a second supporting link 232 disposed to cross the first supporting link 231 and rotatably connected at a crossing position.

Wherein the first support link 231 has a first end rotatably coupled to the housing 21 and the second support link 232 has a first end slidably coupled to the housing 21. And one of the first support link 231 and the second support link 232 has a second end rotatably coupled to the air intake damper 22 and the other has a second end slidably coupled to the air intake damper 22.

Referring to fig. 2, the air intake damper 22 of the present embodiment is vertically disposed, and the supporting means 23 includes a first supporting link 231 and a second supporting link 232 disposed to intersect and rotatably connected at an intersecting position, the first supporting link 231 is longitudinally aligned with a first end and a second end of the second supporting link 232 are also longitudinally aligned (i.e., the projections on the horizontal plane are located at the same position), and the intersecting position is located at the center of the respective lengths of the first supporting link 231 and the second supporting link 232. So that when the magnitude of the angle between the first support link 231 and the second support link 232 is changed, the first end of the first support link 231 and the second end of the second support link 232 are moved closer to or away from each other, respectively, the first end of the first support link 231 and the second end of the second support link 232 are moved away from or closer to each other.

In some embodiments where the air intake baffle 22 is disposed obliquely, or the surfaces of the air intake baffle 22 are not vertically planar, the first end or the second end of the first support link 231 and the second support link 232 may not be longitudinally aligned, and the intersecting position may not be centered on the respective lengths of the first support link 231 and the second support link 232. The supporting means 23 can guide the air inlet damper 22 to move forward and backward to open and close the air inlet as long as the first end of the second support link 232 moves vertically up and down while the first end of the first support link 231 is fixed.

In some alternative embodiments, the air conditioner indoor unit 20 further includes a driving device (not shown). The driving device is used for driving the first end of the second support link 232 to move up and down.

Since the first end of the first support link 231 is fixed, the first end of the second support link 232 is driven to move up and down by the driving device, so that the second end of the second support link 232 can translate back and forth, and simultaneously the second end of the first support link 231 moves up and down synchronously with the first end of the second support link 232 and moves back and forth synchronously with the second end of the second support link 232. As the second ends of the first and second support links 231 and 232 move, the air inlet damper 22 connected to the second ends of the first and second support links 231 and 232 moves back and forth accordingly, thereby opening or closing the air inlet.

The driving means may be various electric driving means including an electric hydraulic ram, an electric ball screw, and the driving means is connected to the first end of the second support link 232 and drives the first end of the second support link 232 upward or downward.

In the embodiment shown in fig. 2, the first end of the first support link 231 is located above the first end of the second support link 232, so that the driving means may be disposed below the first end of the second support link 232, thereby pushing the first end of the second support link 232 upward to push the air intake flap 22 forward to open the air intake, or pulling the first end of the second support link 232 downward to pull the air intake flap 22 rearward to close the air intake. The driving means may also be provided above the first end of the second support link 232. Here, lower and upper include right upper and obliquely upper.

In other embodiments, the first end of the first supporting link 231 may be located below the first end of the second supporting link 232, but the principle of opening and closing the air inlet is similar, so that the description thereof will not be repeated.

It should be noted that, in this embodiment, the air inlet may be opened or closed automatically or manually, that is, in some embodiments in which the indoor unit 20 of the air conditioner is not provided with a driving device, the user may also manually push or pull the air inlet baffle 22, where the air inlet baffle 22 is supported and guided by the supporting device 23, and can be opened or closed along a specific direction and maintain the opened or closed state.

In some alternative embodiments, the support 23 further comprises a first sliding groove 233 and a second sliding groove 234.

A first sliding groove 233 fixed to the housing 21 in a longitudinal direction, a sliding block 232A provided in the first sliding groove 233, the sliding block 232A in the first sliding groove 233 rotatably connected with the first end of the second support link 232 to restrict the first end of the second support link 232 from sliding along the first sliding groove 233, and

The second sliding groove 234 is longitudinally fixed to the air intake damper 22, at least one sliding block 231B and/or 232B is provided in the second sliding groove 234, and the sliding block 231B and/or 232B in the second sliding groove 234 is rotatably connected to the second end of the first support link 231 and/or the second support link 232, thereby restricting the second end of the first support link 231 and/or the second support link 232 from sliding along the second sliding groove 234.

Fig. 3 is a schematic perspective view of an indoor unit 20 of an air conditioner according to another embodiment of the present utility model, in which, in order to more clearly and intuitively illustrate the structure of a supporting device 23, fig. 3 conceals other devices, components and structures except for a housing 21, an air intake baffle 22 and the supporting device 23 of the indoor unit 20 of the air conditioner, and illustrates positions of the air intake baffle 22 and the supporting device 23 when the air intake is closed in a dotted line.

Fig. 2 and 3 show an exemplary embodiment of a support device 23 and an air intake flap 22, respectively. In the embodiment shown in fig. 2, a first end of the first support link 231 is rotatably connected to the housing 21 and a second end of the second support link 232 is rotatably connected to the air intake damper 22. The sliding block 232A in the first sliding groove 233 is rotatably coupled to the first end of the second support link 232, thereby restricting the first end of the second support link 232 from sliding up and down along the first sliding groove 233. The sliding block 231B in the second sliding groove 234 is rotatably coupled to the second end of the first support link 231, thereby restricting the second end of the first support link 231 from sliding up and down along the second sliding groove 234.

Although the first slide groove 233 in the embodiment of fig. 2 is further provided therein with the slide block 231A connected to the first support link 231 and the second slide groove 234 is further provided therein with the slide block 232B connected to the second support link 232, the first end of the first support link 231 in the embodiment may be rotatably connected to the housing 21 indirectly through the slide block 231A fixed in the first slide groove 233 as in the embodiment of fig. 2, or may be directly connected to the housing 21 without the slide block 231A. Similarly, the second end of the second support link 232 in this embodiment may be rotatably connected to the air intake damper 22 via a sliding block 232B fixed in the second sliding groove 234 as shown in the embodiment of fig. 2, or may be directly connected to the air intake damper 22 without the sliding block 232B.

In the embodiment shown in fig. 2, since the first end of the first support link 231 is fixed relative to the housing 21 and the second end of the second support link 232 is fixed relative to the air intake damper 22, the air intake damper 22 keeps translating back and forth without shifting up and down during the opening and closing process as schematically shown in the dashed line to solid line positions in fig. 2.

The driving device in this embodiment may be directly connected to the first end of the second support link 232, or may be connected to the slider 232A so as to be indirectly connected to the first end of the second support link 232.

The air inlet baffle 22 in this embodiment can move in parallel in the front-rear direction, so that the air inlet baffle 22 can be well applied to an environment with insufficient space above the air conditioner indoor unit 20, and the air inlet baffle 22 cannot collide with a cabinet, a wall surface or other objects above the air conditioner indoor unit 20 when being opened.

In the embodiment shown in fig. 3, the first and second ends of the first support link 231 are rotatably connected to the housing 21 and the air intake baffle 22, respectively. The sliding block 232A in the first sliding groove 233 is rotatably coupled to the first end of the second support link 232, thereby restricting the first end of the second support link 232 from sliding up and down along the first sliding groove 233. The sliding block 232B in the second sliding groove 234 is rotatably coupled to the second end of the second support link 232, thereby restricting the second end of the second support link 232 from sliding up and down along the second sliding groove 234.

Similar to the embodiment shown in fig. 2, the first support link 231 in this embodiment may be indirectly connected to the housing 21 by a sliding block 231A fixed in the first sliding groove 233 and indirectly connected to the air intake damper 22 by a sliding block 231B fixed in the second sliding groove 234 as shown in the embodiment of fig. 3, but the sliding blocks 231A and 231B may not be provided and may be directly connected to the housing 21 and the air intake damper 22.

In the embodiment shown in fig. 3, since the first end of the first support link 231 is fixed relative to the housing 21, and the second end of the first support link 231 is fixed relative to the air intake damper 22, the air intake damper 22 moves upward while moving forward during the opening process, and thus the support device 23 drives the air intake damper 22 to move obliquely upward as indicated by the dashed line to the solid line in fig. 3.

In this embodiment, when the air inlet is opened, since the air inlet baffle 22 is located obliquely above the air inlet, a part of the air inlet can draw air flow from the right front without bypassing the air inlet baffle 22, so the air inlet effect of this embodiment is better than that of the embodiment shown in fig. 2, and the air inlet baffle 22 is suitable for the environment where the space above the indoor unit 20 of the air conditioner is sufficient and the air inlet baffle 22 is supported to move obliquely above.

In some alternative embodiments, the number of sliding blocks in the second sliding groove 234 is two, and the sliding blocks 231B and 232B in the two second sliding grooves 234 are rotatably connected to the second ends of the first support link 231 and the second support link 232, respectively.

And the supporting means 23 further comprise a locking member 235. The locking member 235 is detachably disposed on the second sliding groove 234 for fixing the sliding block 231B or 232B connected to the second end of the first support link 231 or the second support link 232 with the second sliding groove 234, thereby rotatably connecting the second end of the first support link 231 or the second support link 232 with the air intake damper 22.

Referring to fig. 2 and 3, in the present embodiment, by providing the locking member 235, one of the two sliding blocks 231B or 232B in the second sliding groove 234 is prevented from moving in the second sliding groove 234, so that the air intake damper 22 is switched to be translated back and forth as shown in fig. 2 or to be opened and closed obliquely upward as shown in fig. 3. When the user installs the indoor unit of the air conditioner, the indoor unit 20 of the air conditioner can be conveniently switched according to the installation environment space and the use requirement.

The locking member 235 may be a removable member, and the second sliding groove 234 is formed with a through hole at a position corresponding to the two sliding blocks 231B and 232B when the air inlet damper 22 is closed, and when the locking member 235 is inserted into one through hole, the sliding block 231B or 232B at the corresponding position is prevented from moving upwards, so that the weight of the air inlet damper 22 is borne on the corresponding sliding block 231B or 232B. The locking member 235 may be a screw, a buckle, or other locking member 235 that can be used to prevent the sliding block 231B or 232B in the second sliding groove 234 from moving upward or in any direction.

Fig. 4 is a schematic cross-sectional view of an air conditioner indoor unit 20 according to one embodiment of the present utility model;

Referring to fig. 4, in some alternative embodiments, the air inlet is opened at an upper portion of the front surface of the housing 21, and the air outlet is opened at a lower portion of the front surface of the housing 21.

The air conditioner indoor unit 20 of the present embodiment may be an embedded air conditioner indoor unit 20, that is, the air conditioner indoor unit 20 is embedded in a cabinet. Unlike the conventional wall-mounted air conditioner indoor unit 20, the embedded air conditioner indoor unit 20 is embedded and arranged in a cabinet, so that the air conditioner indoor unit 20 is hidden in appearance, and the household arrangement is more attractive.

In order to adapt to the opening of the cabinet, the air conditioner indoor unit 20 of the present embodiment has an air inlet at the upper portion of the front surface of the housing 21, and an air outlet at the lower portion of the front surface of the housing 21, that is, the front surface of the housing 21 has both the air inlet and the air outlet, that is, the air inlet and the air outlet of the air conditioner indoor unit 20 are located at the same side and correspond to the opening position of the cabinet, so that the air conditioner indoor unit 20 can simultaneously intake air and exhaust air from the front side.

In some alternative embodiments, the air conditioner indoor unit 20 further includes an air supply fan 24, a heat exchanger 25, and an air intake baffle 26.

An air blower 24 is provided in the housing 21 for causing an air flow to be formed from the air intake into the air conditioner indoor unit 20 and from the air outlet. The heat exchanger 25 is disposed in the housing 21 and between the air inlet and the air blower 24, for exchanging heat with the air flow entering the air conditioner indoor unit 20 from the air inlet. An air inlet partition 26 is horizontally disposed in the housing 21 and has one end adjacent to the air inlet and one end adjacent to the heat exchanger 25, thereby dividing the air flow entering the air conditioner indoor unit 20 from the air inlet into upper and lower portions.

An air inlet partition 26 is horizontally disposed in the housing 21 and has one end adjacent to the air inlet and one end adjacent to the heat exchanger 25, thereby dividing the air flow entering the air conditioner indoor unit 20 from the air inlet into upper and lower portions.

Referring to fig. 4, in order to improve the heat exchange efficiency, the air conditioner indoor unit 20 of the present embodiment is provided with a heat exchanger 25 on the upper peripheral side of the air blower 24, wherein a part of the heat exchanger 25 is close to and faces the air inlet of the air conditioner indoor unit 20, and a part of the heat exchanger 25 is far from the air outlet due to bending backward and downward.

In order to avoid that the air flow of the air intake passes through only the front half heat exchanger 25 near the air intake and the rear half heat exchanger 25 does not or does not participate in heat exchange, an air intake partition 26 is particularly disposed in the housing 21, and one end of the air intake partition 26 is near the air intake and one end is near the heat exchanger 25, thereby dividing the air flow entering the indoor unit 20 of the air conditioner from the air intake into upper and lower parts.

The air conditioner indoor unit 20 of the embodiment utilizes the interval of the air inlet baffle 26 to enable the air flow entering the air conditioner indoor unit 20 from the air inlet of the lower half part to pass through the heat exchanger 25 of the front half part, and simultaneously ensures that the air flow entering the air conditioner indoor unit 20 from the air inlet of the upper half part can flow to and pass through the heat exchanger 25 of the rear half part, thereby fully utilizing the heat exchanger 25 and avoiding accumulation of cold energy.

In the present embodiment, a space is formed between the upper end of the heat exchanger 25 and the upper portion of the housing 21 to allow the air flow to pass therethrough, and the end of the air inlet partition 26 may be close to the upper end of the heat exchanger 25, thereby dividing the heat exchanger 25 into front and rear portions and ensuring that the air flow entering from the air inlet of the upper half is guided to the heat exchanger 25 of the rear half.

In some embodiments of the present application, the air intake partition 26 may be disposed in the housing 21 not horizontally, i.e., inclined or formed in a bent shape, and may divide the air flow entering the indoor unit 20 of the air conditioner from the air intake into two parts. However, the above embodiment may affect the normal flow of the air flow and cause the air intake efficiency of the indoor unit 20 of the air conditioner to be lowered, and thus is not generally the most preferred embodiment.

In some alternative embodiments, the heat exchanger 25 may not be disposed on the upper peripheral side of the blower fan 24 as in the example shown in fig. 4, and may be disposed longitudinally or otherwise in the housing 21, and the air intake partition 26 may be disposed correspondingly with its end portion being located in the middle of the height of the heat exchanger 25, so as to divide the heat exchanger 25 into upper and lower portions opposite the air intake.

In some alternative embodiments, air conditioner indoor unit 20 further includes a first air deflection 31.

The first air deflector 31 is disposed at the air outlet and has a rotation shaft adjacent to the upper side of the air outlet and extending laterally.

Fig. 4 illustrates a position of the first air deflector 31 in an open state, in which the first air deflector 31 of the present embodiment is turned upward around a rotation axis near the upper side of the air outlet, and the air inlet is separated from the air outlet by its own plate body. Therefore, when the first air deflector 31 of this embodiment is opened, the air outlet air flow can be guided by adjusting the rotating height, and the distance between the air outlet and the air inlet is changed, and meanwhile, the air inlet and the air outlet on the upper side and the lower side of the first air deflector are separated, so that the air inlet is prevented from directly sucking the heat exchange air flow blown from the air outlet into the air conditioner indoor unit 20 again, the air inlet and the air outlet effects of the air conditioner indoor unit 20 are optimized, and the heat exchange efficiency and the air supply effect are improved.

In some alternative embodiments, the end of the first air deflector 31 away from the rotation axis thereof is bent toward the air outlet.

Fig. 4 illustrates the airflow direction at the air outlet by using an arrow, and the first air deflector 31 of the present embodiment is bent at one end far from the rotation axis thereof toward the air outlet, thereby forming a concave cambered surface. When the first air guide plate 31 is opened and the air conditioner indoor unit 20 is discharged, the discharge air flow direction at the discharge port is guided to be inclined downward along the arc surface.

Because the air outlet of the embedded air conditioner indoor unit 20 is located at the front side thereof, the shape of the first air deflector 31 of the present embodiment can ensure that the air flow can be blown obliquely downwards under the condition of large opening of the air outlet, so as to avoid the situation that the air supply height of the air conditioner indoor unit 20 is too high to meet the direct blowing demands of some users. And the air flow blown from the air outlet is guided by the first air deflector 31, and the flowing direction of the air flow tends to be far away from the air inlet, so that a certain effect is also achieved for preventing the air flow blown from the air outlet from being directly sucked into the air inlet again.

The first air deflector 31 in this embodiment may be formed by bending the whole plate body and forming an arc shape as a whole, or may be formed by bending only the surface of the first air deflector 31 facing one side of the air outlet and forming a flat surface on the other side to adapt to the shape of the air outlet as shown in fig. 4.

In some alternative embodiments, the air conditioner indoor unit 20 further includes a supply air duct 27, a second air deflection 32, and a third air deflection group.

An air supply duct 27 is provided in the housing 21, and one end is connected to an air outlet. The second air guide plate 32 is disposed in the air supply duct 27 and has a rotation axis extending laterally near the lower surface of the air supply duct 27 for guiding the air outlet direction of the air conditioner indoor unit 20. The third air deflector group is disposed in the air supply duct 27 and includes a plurality of third air deflectors 33 distributed in a transverse direction, and each of the third air deflectors 33 has a rotation shaft extending in a longitudinal direction for guiding an air outlet direction of the air conditioner indoor unit 20.

Referring to fig. 4, the air supply duct 27 of the present embodiment has one end connected to the air outlet and one end connected to the air supply fan 24, so as to guide the air flow formed by the air supply fan 24 to blow toward the air outlet. The first air deflector 31 is disposed at the air outlet, and both ends of its rotation shaft are connected to both lateral side walls of the air supply duct 27. The second air deflector 32 is disposed adjacent to the lower surface of the air supply duct 27, and both ends of its rotation shaft may be connected to both lateral side walls of the air supply duct 27.

The second air guide plate 32 may swing upward from a position proximate to the lower surface of the air supply duct 27, thereby adjusting the air outlet height of the air conditioner indoor unit 20. When the swing height of the second air deflector 32 is higher, the size of the air outlet can be reduced, so that the distance between the air outlet and the body feeling wind speed can be changed in cooperation with the change of the rotation speed of the air supply fan 24. For example, when the second air guide plate 32 swings to a high height and the air outlet is reduced while the rotational speed of the blower fan 24 is not changed, the actual air outlet speed of the air conditioner indoor unit 20 is increased due to the reduction of the air outlet. When the rotation speed of the air supply fan 24 decreases, the swing of the second air deflector 32 is used to reduce the size of the air outlet, so that the actual air outlet speed of the air conditioner indoor unit 20 can be maintained stable, and the air supply quantity of the air conditioner indoor unit 20 is reduced under the condition that the somatosensory air speed is basically unchanged, so that the environmental temperature can be conveniently regulated.

Only one third air deflection 33 of the third air deflection group can be seen in fig. 4, but it will be appreciated that a plurality of third air deflection 33 of the present embodiment are arranged laterally side by side within the supply air duct 27. In some alternative embodiments, the plurality of third air deflection panels 33 in the third air deflection panel may be synchronously controlled to rotate and adjust the lateral air outlet direction of the air conditioner indoor unit 20.

In the example shown in fig. 4, the third air deflection group is provided on the lower surface of the supply air duct 27, and in other alternative embodiments, the third air deflection group may also be provided on the upper surface of the supply air duct 27.
