Detailed Description

Air conditioner internal units can be generally divided into air conditioner hanging units and air conditioner cabinet units according to the installation mode. In the related art, for a cabinet air conditioner, a front shell of the cabinet air conditioner is generally provided with two air outlets, the two air outlets are respectively provided with a movable sliding plate, and the two sliding plates are respectively provided with a driving device, so that the sliding plates can be controlled to move relative to the front shell through the respective driving devices, and the opening and closing of the two air outlets are controlled. However, in the above cabinet air conditioner, because there is a difference in performance of the driving motors in different driving devices, there is a high risk that the two motors are not synchronized, which is very likely to cause a problem that the two sliding plates slide non-uniformly.

In order to overcome the above problems, the present embodiment provides an air conditioner internal unit and an air conditioner, and driving motor can drive the slide motion corresponding to two air outlets respectively through two sets of transmission racks, and driving motor can two slides move between the first position of opening the air outlet and the second position with the air outlet pipe wall in synchronous drive, does benefit to and avoids the inconsistent problem of two slides slip, and does benefit to and simplifies the assembly step, simplifies the circuit layout, does benefit to the cost that reduces the air conditioner internal unit.

The structure, function and implementation process of the water tank device of the present embodiment will be described below with reference to the accompanying drawings.

The embodiment provides an air conditioner which can comprise an air conditioner external unit and an air conditioner internal unit which are connected. An outdoor unit of an air conditioner generally includes an outdoor heat exchanger. An air conditioner indoor unit generally includes an indoor heat exchanger and a throttle device. The air conditioner also comprises a compressor, and the compressor can be arranged on an air conditioner external unit or an air conditioner internal unit. When the air conditioner performs refrigeration work, the compressor compresses a gaseous refrigerant into a high-temperature high-pressure gaseous state, and sends the gaseous refrigerant to the outdoor heat exchanger for cooling, the high-temperature high-pressure gaseous refrigerant is cooled and then becomes a medium-temperature high-pressure liquid refrigerant, the medium-temperature high-pressure liquid refrigerant is throttled and reduced by the throttling device and becomes a low-temperature low-pressure gas-liquid mixture, and the low-temperature low-pressure gas-liquid mixture absorbs heat in air by the indoor heat exchanger and is vaporized into a gaseous state, so that the refrigeration effect is achieved; the gaseous refrigerant returns to the compressor to continue to be compressed, and the circulation is continued to carry out refrigeration.

The indoor unit can be an air conditioner hanging machine or a cabinet air conditioner. For convenience of description, the present embodiment specifically exemplifies a cabinet air conditioner, but it should be understood that the structure described below is equally applicable to a hanging air conditioner without contradiction.

Fig. 1 is a schematic structural view of a slide plate of an air conditioner indoor unit according to an exemplary embodiment of the present invention when an air outlet is closed; fig. 2 is a schematic structural view of a slide plate of an air conditioner indoor unit according to an exemplary embodiment of the present invention when an air outlet is opened; fig. 3 is a schematic structural diagram of a driving mechanism when a slide plate closes an air outlet in an air conditioner indoor unit according to an exemplary embodiment of the present invention; fig. 4 is a schematic structural diagram of a driving mechanism when a slide plate opens an air outlet in an air conditioner indoor unit according to an exemplary embodiment of the present invention.

Referring to fig. 1 to 4, the indoor unit further includes a casing 100, a driving mechanism 500, and a sliding plate 300. An indoor heat exchanger, a throttle device, and the like may be provided in the cabinet 100. Alternatively, the cabinet 100 may include an upper cabinet 110 and a lower cabinet 120. The lower housing 120 may be used to house an air conditioner compressor and other devices. The upper case 110 may be used to house an indoor heat exchanger and the like.

The upper case 110 may include two side panels disposed opposite to each other and a front door panel disposed between the two side panels. The front door panel may be substantially perpendicular to the side panels. Air outlet 130 of the air conditioner internal unit can be specifically arranged on the front door panel and arranged in the area of the front door panel close to the side panels, that is, air outlet 130 can be arranged in the edge area of the front door panel close to the two side panels.

In order to improve the refrigeration effect, the air outlets 130 are arranged on the left side and the right side of the front door plate of the air conditioner indoor unit. Alternatively, a certain gap may be formed between the front door panel and the two side panels as the air outlet 130. In a specific implementation, in order to increase the air outlet area, a plurality of air deflectors 140 may be disposed at the air outlet 130, each air deflector 140 extends along the vertical direction, and the plurality of air deflectors 140 are disposed between the front door panel and the side panel and are spaced apart from each other along the circumferential direction of the casing 100, so as to improve the guiding effect of the air blown out from the air outlet 130.

An air inlet grille which can supply air to enter an air conditioner indoor unit can be arranged behind the front door panel. Taking the air conditioner internal unit in the cooling mode as an example, hot air can enter the upper casing 110 from the air inlet grille under the action of negative pressure in the air conditioner internal unit, and form cold air after passing through the heat exchanger, and then blow out to the indoor environment through the air outlet 130, thereby playing a role in reducing the ambient temperature.

In order to automatically open and close the air outlet 130 at each side, sliding plates 300 may be respectively disposed at the air outlets 130 at both sides of the front door panel. The drive mechanism 500 is drivingly connected to the two slide plates 300. The driving mechanism 500 drives the sliding plate 300 to move, so that the sliding plate 300 can shield the air outlet 130 to expose the wall of the air outlet 130, and can open the air outlet 130 to expose the air outlet 130 to the external environment.

Specifically, the driving mechanism 500 includes: the driving device comprises a driving motor 510 and two sets of transmission racks 530, wherein the output end of the driving motor 510 is provided with a transmission gear 520, the two sets of transmission racks 530 are respectively meshed with the transmission gear 520, and the two sets of transmission racks 530 are respectively connected with the two sliding plates 300. The driving motor 510 is used for driving the two sets of driving racks 530 to move along a first direction so as to drive the two sliding plates 300 to move to a first position where the air outlet 130 is opened; the driving motor 510 is further configured to drive the two sets of driving racks 530 to move along a second direction to drive the two sliding plates 300 to move to a second position where the air outlet 130 is closed, where the first direction is opposite to the second direction.

The driving motor 510 may be mounted to the front door panel, and the driving motor 510 may also be mounted to other positions of the cabinet 100. Taking the example that the driving motor 510 is installed to the front door panel, the driving motor 510 can be fixed on the front door panel in a detachable manner such as a screw or a buckle, so that the driving motor 510 is convenient to replace and maintain on the basis of ensuring the connection stability between the driving motor 510 and the front door panel. Of course, the fixing manner of the driving motor 510 and the front door panel is not limited thereto, and for example, the driving motor 510 may be fixed to the front door panel by welding, bonding, or the like.

The output shaft of the driving motor 510 can drive the transmission gear 520 to rotate. The transmission gear 520 may be integrally provided with an output shaft of the driving motor 510, the transmission gear 520 may also be welded to the output shaft of the driving motor 510, and the transmission gear 520 may also be keyed to the transmission gear 520.

Two sets of driving racks 530 engaged with the gears are arranged in the axial direction of the driving gear 520. Illustratively, the drive rack 530 may include a rack side and a connecting side. The rack side is for engaging with the pinion 520. The connection side is used for connection with the slide board 300. Thus, the transmission rack 530 can drive the sliding plate 300 to move together along the predetermined track.

In this example, when the air conditioner indoor unit needs to work, driving motor 510 starts, driving motor 510 corotation (or driving motor 510 rotates along the clockwise), driving motor 510 drives drive gear 520 and rotates, under the meshing effect of drive gear 520 and driving rack 530, driving rack 530 can drive slide 300 and move along first direction, air outlet 130 will expose gradually in the external environment of air conditioner indoor unit this moment, when air outlet 130 exposes the external environment in the air conditioner completely, slide 300 moves to the first position of opening air outlet 130, the wind of air conditioner indoor unit output can follow air outlet 130 and get into indoor environment.

When the air conditioner internal unit finishes working, driving motor 510 reverses (or driving motor 510 rotates along the counterclockwise), driving motor 510 drives transmission gear 520 to rotate, under the meshing effect of transmission gear 520 and transmission rack 530, transmission rack 530 can drive slide plate 300 to move along the second direction opposite to the first direction, slide plate 300 will shelter from air outlet 130 gradually at this moment, when slide plate 300 shelters from air outlet 130 completely, slide plate 300 moves to the second position of closing air outlet 130, slide plate 300 isolates air outlet 130 and air conditioner internal unit's external environment completely.

It should be noted that, during the above operation, the forward rotation and the reverse rotation of the driving motor 510 are only used to distinguish two different rotation directions during the opening and closing process. It is understood that, in some examples, the driving motor 510 may be in a reverse rotation state when the air outlet 130 is opened, and the driving motor 510 may be in a forward rotation state when the air outlet 130 is closed.

Optionally, the driving gear 520 and the driving rack 530 may be engaged in a horizontal direction, such that, when the slide board 300 is downwardly deviated by a certain distance under the action of gravity for a long time, the driving rack 530 may be deviated by a certain distance in a vertical direction along with the slide board 300, and the axial direction of the driving gear 520 is parallel to the vertical direction, such that, even if the driving rack 530 is downwardly deviated by a certain distance along with the slide board 300, the engagement between the driving rack 530 and the driving gear 520 may not be affected, thereby ensuring the operational reliability of the driving mechanism 500 and ensuring the stability of the slide board 300 during the movement process.

Optionally, in order to make the structure of the air conditioner internal unit more compact, the distance between the two sliding plates 300 in the first position is smaller than the distance between the two sliding plates 300 in the second position. In other words, movement in the first direction is a phase movement and movement in the second direction is an opposite movement. That is, the driving motor 510 is configured to drive the two sets of driving racks 530 to move in opposite directions to drive the two sliding plates 300 to move to the first position where the air outlet 130 is opened; the driving motor 510 is further configured to drive the two sets of driving racks 530 to move away from each other to drive the two sliding plates 300 to move to the second position where the air outlet 130 is closed.

Optionally, a concave portion is formed by recessing the middle portion of the front door panel between the air outlets 130 at the two sides toward the inside of the cabinet, and the middle decorative panel is covered on the concave portion. In some examples, by mounting the middle trim panel in front of the front door panel such that the middle trim panel is at the same level as the front side panel of the lower housing 120 of the housing 100, it is possible to secure a sufficient gap between the middle trim panel and the front door panel to receive the slide board 300.

Of course, in other examples, the distance between two sliding plates 300 in the first position may be greater than the distance between two sliding plates 300 in the second position; in other words, movement in the first direction is back-to-back movement and movement in the second direction is back-to-back movement.

The air conditioner provided by the embodiment, the driving motor 510 can respectively drive the sliding plates 300 corresponding to the two air outlets 130 to move through the two sets of transmission racks 530, the driving motor 510 can synchronously drive the two sets of transmission racks 530 to move along a first direction to drive the two sliding plates 300 to move to a first position for opening the air outlets 130, and can also synchronously drive the two sets of transmission racks 530 to move along a second direction opposite to the first direction to drive the two sliding plates 300 to move to a second position for closing the air outlets 130, so that the problem that the two sliding plates 300 are inconsistent in sliding is avoided, the assembly steps are simplified, the circuit layout is simplified, and the cost of an indoor unit of the air conditioner is reduced.

In one possible implementation, the two sets of driving racks 530 are spaced apart along the axial direction of the driving gear 520, so as to avoid the two sets of driving racks 530 interfering with each other. The axial spacing distance can be specifically set according to actual needs.

Alternatively, the two sets of transmission racks 530 in the driving mechanism 500 are disposed to intersect in the orthographic projection of the upper end surface of the housing 100. That is to say, the orthographic projections of the two sets of transmission racks 530 on the horizontal reference surface are intersected, so that the driving motor 510 can drive the two sets of transmission racks 530 to move synchronously, and further drive the two sliding plates 300 to move synchronously.

Optionally, two opposite long sides of the driving rack 530 are respectively provided with engaging teeth engaged with the driving gear 520. The driving racks 530 are oppositely disposed, and opposite long sides of the driving racks 530 are respectively engaged with the driving gears 520. Thus, according to practical situations, the transmission gear 520 can be connected with any one of the two sliding plates 300, so that the re-assembly caused by the assembly error of the transmission rack 530 in the direction can be reduced, and the assembly efficiency of the driving mechanism 500 can be improved.

In one possible implementation manner, the driving mechanism 500 further includes a motor box, the driving motor 510 is installed in the motor box, and the motor box is installed in the casing 100; the motor box is provided with dodges the mouth, dodges the mouth and is used for supplying the output or the transmission rack 530 of driving motor 510 to stretch out the motor box outside.

In some examples, an output shaft of the driving motor 510 extends out of the bypass opening and is connected with a transmission gear 520 arranged outside the motor box, so that the transmission gear 520 is driven.

In other examples, the driving motor 510 and the output shaft of the driving motor 510 may be accommodated in the motor case, and at this time, a part of the transmission gear 520 fixedly connected to the output shaft may be directly accommodated in the motor case; meanwhile, another portion of the transmission gear 520 protrudes from the escape opening of the motor case to the outside of the motor case to stably engage with the transmission rack 530.

Optionally, the motor box is provided with a first limiting groove, and the two sets of transmission racks 530 are respectively slidably disposed in the corresponding first limiting grooves, so as to ensure that the two sets of transmission gears 520 do not interfere with each other, and to facilitate avoiding the two sets of transmission gears 520 from shifting, thereby ensuring the reliability of the engagement between the transmission gears 520 and the driving motor 510.

The first limiting groove may be disposed on a side surface of the motor case facing the transmission gear 520 and the sliding plate 300. An avoidance opening of the motor box is arranged behind the first limit groove, one part of the transmission gear 520 is accommodated in the motor box, and the other part of the transmission gear 520 extends out of the avoidance opening and is meshed with the transmission rack 530 which is arranged in the first limit groove in a sliding mode.

The driving rack 530 may be fixed in the second limiting groove by welding, clamping, screwing, bonding, or the like. The second limit groove has at least a part which can be opposite to the first limit groove, so that the second limit groove can limit the corresponding moving space of the transmission gear 520 together with the first limit groove on the motor box, thereby further ensuring that the two groups of transmission gears 520 can not interfere and further ensuring the meshing reliability of the transmission gear 520 and the driving motor 510.

The driving rack 530 may be in the shape of an arc, which is disposed around the vertical axis of the cabinet 100; when the casing 100 is also configured in an arc-shaped structure around its vertical axis, the driving rack 530 may extend along the circumferential direction of the casing 100, so that the sliding plate 300 is moved along the circumferential direction of the casing 100 by the driving rack 530, i.e., the sliding plate 300 is moved along the circumferential surface of the casing 100.

The shape of the drive rack 530 matches the shape of the sled 300 to facilitate the mating of the drive rack 530 with the sled 300.
