Referring to fig. 1, fig. 1 is a transverse sectional view of an air conditioning indoor unit 1 according to one embodiment of the present utility model. The utility model provides an air conditioner indoor unit 1, wherein the air conditioner indoor unit 1 can be a household air conditioner or a central air conditioner. Specifically, the specific form of the air conditioning indoor unit 1 may be various forms such as split wall hanging, split standing, integral, patio type, and the like. The embodiment of the utility model does not limit the concrete form of the air conditioner. Fig. 1 illustrates only an embodiment of a floor air conditioner.

The air conditioning indoor unit 1 may include a cabinet 10, an evaporator, and a cross flow fan. The air supply port 12 is provided on the front side of the casing 1010. The casing 1010 is formed with a middle air duct 30 and two heat exchange air ducts 20, the middle air duct 30 has a middle air outlet 31 opened forward, the middle air outlet 31 is located behind the air supply outlet 12, and an air outlet channel 180 is formed between the middle air outlet 31 and the air supply outlet 12. The two heat exchange air channels 20 are arranged side by side along the transverse direction of the casing 1010, and the outlets 21 of the two heat exchange air channels are respectively positioned at two transverse sides of the air outlet channel 180, so that the blown heat exchange air flow and the air flow flowing out of the middle air outlet 31 are mixed in the air outlet channel 180.

Each heat exchange air duct 20 is defined by two air duct walls arranged at a lateral interval, and the outlet ends of the two air duct walls form an outlet 21 of the heat exchange air duct 20. The heat exchange air duct 20 is used for blowing out heat exchange air flow, namely cold air produced by the air conditioner in a refrigerating mode or hot air produced by the air conditioner in a heating mode. The outlets 21 of the two heat exchange air channels 20 are opposite, which means that one heat exchange air channel 20 outputs air towards the left or the left front, and the other heat exchange air channel 20 outputs air towards the right or the right front, and the air flows of the two heat exchange air channels can be intersected without the guidance of an air guiding device. An air deflector 50 may be provided at each outlet 21 to adjust the direction of air flow/open and close the outlet 21.

The air flow blown by the middle air duct 30 may be non-heat exchange air flow, for example, indoor room temperature air flow, purified air flow, humidified air flow, fresh air flow, etc. The non-heat exchange air flow and the heat exchange air flow are mixed before being blown out of the air supply port 12, so that the air supply temperature during refrigeration is raised to a certain extent, the air supply temperature during heating is lowered to a certain extent, and the air supply air flow is cooled and not cooled (during refrigeration) and heated and not dried (during heating). The three directional airflows impinge on each other and mix vigorously within the air outlet channel 180, mixing very uniformly. The mixed air flows are blown to the indoor environment from the air supply outlet 12, the temperature is more appropriate, and the wind feeling experience of a user is better.

A through-flow fan 80 is arranged at the inlet of each heat exchange air duct 20, and the axis of the through-flow fan 80 extends along the vertical direction. A heat exchanger 40 is disposed between each cross-flow fan 80 and the air intake. Air conditioners may utilize vapor compression refrigeration cycle systems for cooling/heating. The heat exchanger 40 is an "indoor heat exchanger" in the refrigeration cycle, and forms a cycle together with an outdoor heat exchanger, a compressor, a throttle device, and other refrigeration components. Under the driving of the cross-flow fan 80, indoor air enters the casing 1010 through the air inlet to exchange heat with the heat exchanger 40 to form heat exchange air flow, and the heat exchange air flow enters the heat exchange air duct 20.

Referring to fig. 2, fig. 2 is a schematic view of a front casing in the indoor unit 1 of the air conditioner according to one embodiment of the present utility model. In some embodiments, the indoor unit 1 may further include a fragrance device 70, and the fragrance device 70 is mounted with solid fragrance to emit fragrance smell so as to improve smell of the indoor space. In some embodiments, the fragrance means 70 can be arranged in the air outlet channel 180, and the fragrance gas can be forcefully impacted in the air outlet channel 180, so that the fragrance gas can be dispersed more quickly.

The drive mechanism 740 is disposed in the mounting cavity 714 and is configured to controllably actuate the fragrance housing 720 in a translation along the height of the housing 710 between a retracted position and an extended position, and is capable of retracting the solid fragrance entirely into the mounting cavity 714 through the first opening 712 when the fragrance housing 720 is in the retracted position, and is capable of extending at least a portion of the solid fragrance out of the mounting cavity 714 through the first opening 712 when the fragrance housing 720 is in the extended position.

In some embodiments, a first opening 712 is provided corresponding to a fragrance housing 720, i.e., a fragrance housing 730, a solid fragrance, and a set of driving mechanisms 740. In some specific embodiments, the number of the first openings 712 may be further set to be plural, that is, the fragrance means may include a plurality of solid fragrances controlled independently of each other, one or more of which may be selected by a user according to preference to improve the smell in the room. In order to more clearly describe the working principle of the present utility model, one of the solid aromatherapy will be described as an example.

When the driving mechanism 740 receives the instruction for opening the fragrance, the fragrance support 720 can be driven to move upwards, so as to drive the fragrance housing 730 on the fragrance support 720 and the solid fragrance therein to move upwards, and finally, at least part of the housing body of the fragrance housing 730 extends out of the mounting cavity 714 through the first opening 712. The peripheral wall and/or top wall of the fragrance housing 730 is provided with air flow holes (not shown), so that the fragrance emitted from the solid fragrance can be sufficiently emitted into the air through the air flow holes after the fragrance extends out of the mounting cavity 714, thereby improving the smell of the indoor air.

When the driving mechanism 740 receives the instruction for closing the fragrance, the fragrance support 720 can be driven to move downwards, so that the fragrance housing 730 on the fragrance support 720 and the solid fragrance therein can be driven to move downwards, and finally the fragrance housing 730 is integrally retracted into the mounting cavity 714 through the first opening 712, so that the fragrance housing 730 and the solid fragrance therein are sealed relatively by the stretched housing 710, and fragrance emission is reduced.

The casing 710 of the aromatherapy device 70 may be further embedded under the wall surface of the air outlet channel 180 of the indoor unit 1, and the top of the casing 710 is flush with the wall surface of the air outlet channel 180. For example, the air outlet channel 180 of the indoor unit 1 is in a vertical strip shape, and the casing 710 of the aromatherapy device 70 can be embedded into the lower wall of the air outlet channel 180 and is flush with the lower wall of the air outlet channel 180, so that the operation of a user is facilitated, and the appearance is attractive.

In some embodiments, the driving mechanism 740 further comprises a gear 744, a rack 746, and a driving motor 742, the rack 746 extends along the height direction of the housing 710 and is connected to the bottom of the fragrance housing 720, the gear 744 is meshed with the rack 746, and an output shaft of the driving motor 742 is connected to the gear 744 to drive the fragrance housing 720 to move along the height direction of the housing 710.

Referring to fig. 8, fig. 8 is a schematic diagram illustrating an electric control principle of an indoor unit of an air conditioner according to an embodiment of the present utility model. In some embodiments, the drive motor 742 may also be a stepper motor that can be set with two extreme angular displacements to correspond to the retracted and extended positions, respectively, prior to shipping. In addition, the stepper motor can be electrically connected with a main control board 90 of the indoor unit of the air conditioner. The main control board 90 of the indoor unit of the air conditioner can receive a remote control command or a voice command, for example, a voice command of "fragrance on", "fragrance off". When the main control board 90 receives the instruction for controlling the fragrance to rise and fall, the stepping motor is controlled to rotate according to the instruction, so that the gear 744 is further driven to rotate, and finally the fragrance cover 730 is controlled to rise and fall.

In some embodiments, the aromatherapy device may further comprise a mounting box 750, the mounting box 750 is fixed in the mounting cavity 714, the gear 744 is mounted inside the mounting box 750, and a second opening 752 and a third opening 754 are respectively formed at a top and a bottom of the mounting box 750, which are opposite to each other in a height direction of the housing 710, and the rack 746 is penetrated through the mounting box 750 through the second opening 752 and the third opening 754.

Specifically, the mounting box 750 is disposed below the first opening 712, and the first opening 712, the second opening 752, and the third opening 754 are opposite in the height direction. The rack 746 is inserted into the mounting box 750 through the second opening 752 and the third opening 754, and when the rack 746 moves upward, the top end thereof may protrude out of the mounting box 750 through the second opening 752, and when the rack 746 moves downward, the bottom end thereof may protrude out of the mounting box 750 through the second opening 752 to freely extend and retract up and down inside the housing 710.

In some embodiments, the mounting boxes 750 are formed with limiting plates 756 at opposite edges of the second opening 752, respectively, and the two limiting plates 756 extend upward, respectively, to constrain the trajectory of the motion of the fragrance housing 720.

Because the first opening 712 and the second opening 752 are opposite in the height direction, the two limiting plates 756 respectively extend upwards, and therefore in some specific embodiments, the two limiting plates 756 respectively abut against the edge of the first opening 712, that is, the two limiting plates 756 form a track between the first opening 712 and the second opening 752, so that the track of the movement of the fragrance bracket 720 can be restrained, and the reliability is improved.

In some embodiments, when the fragrance housing 720 is in the extended position, the fragrance housing 720 is within the mounting cavity 714.

Because the fragrance housing 730 is fastened to the fragrance housing 720, when the fragrance housing 720 is in the extended position, the fragrance housing 720 is disposed in the mounting cavity 714, i.e., when the fragrance housing 720 is in the extended position, the bottom thereof is slightly recessed into the mounting, so that the fragrance housing 730 is prevented from being separated from the housing 710.

In addition, the distance between the fragrance housing 720 and the top wall of the housing 710 is not greater than 3cm, for example, 3cm, 2cm, etc., so that not only can the fragrance housing 730 be prevented from being separated from the housing 710, but also the fragrance housing 730 can be extended upwards as much as possible, so as to improve the efficiency of emitting the odor.

In some embodiments, when the fragrance housing 720 is in the retracted position, the top wall of the fragrance housing 730 is flush with the top wall of the housing 710, which not only enables blocking of the first opening 712, prevents dust from entering the mounting cavity 714, but also ensures aesthetics.
