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 a vapor compression refrigeration cycle system 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.

Referring to fig. 3 and 4, fig. 3 is a schematic view of an aromatherapy device in an air conditioner indoor unit according to an embodiment of the present utility model, showing a state in which an aromatherapy cover 720 is retracted into a mounting chamber, and fig. 4 is a schematic view of an aromatherapy device in an air conditioner indoor unit according to an embodiment of the present utility model, showing a state in which the aromatherapy cover 720 is extended out of the mounting chamber.

The fragrance means can further comprise a housing 710, a fragrance housing 720, a transmission rod 730 and a driving rod 740. The housing 710 defines a mounting cavity therein, the top wall of which has an opening 712. The fragrance housing 720 is configured to hold solid fragrance, and is disposed at the opening 712, and is configured to hold solid fragrance. The transmission rod 730 is disposed in the mounting cavity, and includes a main body section 732 extending in a vertical direction and a branch section 734 formed in the main body section 732 and extending in a horizontal direction, and a top end of the main body section 732 is connected to a bottom of the fragrance housing 720.

The driving rod 740 is disposed in the mounting cavity, has a first end connected to the branch section 734 and a second end directly or indirectly connected to the housing 710, and is configured to controllably rotate around the second end in a plane parallel to the main body section 732 and the branch section 734, so as to drive the branch section 734 to move up and down, and drive the main body section 732 to move up and down, so that the fragrance housing 720 can retract into the mounting cavity through the opening 712 or at least partially extend out of the mounting cavity.

In some embodiments, the housing 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 housing 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.

The fragrance housing 720 is provided with air flow holes (not shown), and after the fragrance housing 720 extends out of the installation cavity, the fragrance emitted by the solid fragrance therein can be fully emitted into the indoor environment through the air flow holes, so as to improve the smell of the indoor air. When the fragrance housing 720 is fully retracted into the mounting cavity, the solid fragrance is cut off to emit fragrance.

The main body section 732 of the transmission rod 730 extends in a vertical direction, and the top end is connected to the bottom of the fragrance housing 720, the branch section 734 of the transmission rod 730 extends in a horizontal direction, the first end of the driving rod 740 is connected to the branch section 734, and the second end of the driving rod 740 is directly or indirectly connected to the housing 710. When the driving lever 740 rotates around the second end thereof, the first end applies a force to the branch section 734, which has a component in the height direction, and thus drives the main body section 732 of the driving lever 730 to move up and down, thereby driving the fragrance housing 720 to move up and down, and thus realizing the function of opening and closing fragrance.

Further, the aromatherapy device further comprises a bracket 750, the bracket 750 is fixed to the mounting cavity, and a limit structure is provided on the bracket 750 to restrict the freedom of movement of the main body section 732 in the radial direction, so that the main body section 732 can only move up and down.

Further, since the bracket 750 restrains the main body section 732 from moving only up and down, that is, the bracket 750 restrains the driving branch section 734 from moving only up and down, the force applied to the branch section 734 by the first end of the driving lever 740 has a component force in the horizontal direction, so that the driving lever 730 can be prevented from moving up and down normally, the mechanism of the slider 760 can be used to eliminate the component force in the horizontal direction.

Specifically, the branch section 734 of the transmission rod 730 is provided with a sliding slot 736 along a length direction thereof, the aromatherapy device may further comprise a sliding block 760, the sliding block 760 is slidably disposed in the sliding slot 736, and the second end of the driving rod 740 is hinged to the sliding block 760, such that, during rotation of the driving rod 740, the sliding block 760 slides in the sliding slot 736, such that the first end of the driving rod 740 applies a force to the branch section 734 only in a vertical direction.

In some embodiments, bracket 750 may further include a vertically extending stop section 752 and a mounting section 754 formed in stop section 752 and parallel to branch section 734.

Because the spacing section 752 of the bracket 750 and the main body section 732 of the transfer lever 730 both extend in a vertical direction, i.e., are parallel; the mounting section 754 of the bracket 750 is parallel to the branch section 734 of the drive link 730, and thus the planes of the stop section 752 and the mounting section 754 are formed in the planes of the body section 732 and the branch section 734.

The drive rod 740 may be positioned between the two planes, a first end of the drive rod 740 may extend toward and be hinged to the slider 760 by one hinge section, and a second end of the drive rod 740 may extend toward and be hinged to the mounting section 754 by another hinge section (i.e., the second end of the drive rod 740 is indirectly connected to the housing 710).

In some embodiments, the limiting structure may include at least one protrusion 756, where the protrusion 756 is formed on the limiting section 752 and extends toward the plane of the main body 732 and the branch 734, and the protrusion 756 is formed with a limiting hole 756a, and the main body 732 is inserted into the limiting hole 756a to limit the freedom of the main body 732 moving in the radial direction.

Further, the number of the protrusions 756 is two, and the two protrusions 756 are arranged along the length direction of the limiting section 752, the axes of the limiting holes 756a of the two protrusions 756 are collinear, i.e. the axes of the two limiting holes 756a are in the same vertical direction. In some particular embodiments, two bosses 756 may be located at each end of the spacing section 752.

Further, the branch section 734 is located between the two bosses 756 such that the two bosses 756 can also limit the travel of the transfer lever 730 in the height direction.

Referring to fig. 5, fig. 5 is a schematic diagram illustrating an electric control principle of an indoor unit 1 of an air conditioner according to an embodiment of the present utility model. In some embodiments, the fragrance means can further comprise a drive motor 770, the drive motor 770 also being a stepper motor which can be set with two extreme angular displacements to correspond to the retracted and extended positions, respectively, before shipment. 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 aromatherapy to rise and fall, the stepping motor is controlled to rotate according to the instruction, so that the driving rod 740 is driven to rotate, and finally the aromatherapy cover 720 is controlled to rise and fall.

By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the utility model have been shown and described herein in detail, many other variations or modifications of the utility model consistent with the principles of the utility model may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the utility model.
