This is merely to facilitate describing the utility model and to simplify the description and does not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operate in a particular orientation, and thus should not be construed as limiting the utility model.

Referring to fig. 1, fig. 1 is a transverse sectional view of an indoor unit of an air conditioner according to one embodiment of the present utility model. The utility model provides an air conditioner indoor unit which can be a household air conditioner or a central air conditioner. Specifically, the specific form of the indoor unit of the air conditioner can be various forms such as split wall hanging type, split vertical type, integral type, courtyard 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 indoor unit of the air conditioner may include a cabinet 10, a heat exchanger 40, and a cross flow fan 80. The air supply port 12 is provided on the front side of the casing 10. The casing 10 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 positioned 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 10, 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 10 through the air inlet and exchanges 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 case 710 in an indoor unit of an air conditioner according to an embodiment of the present utility model. In some embodiments, the indoor unit of the air conditioner may further include a fragrance means 70, and the fragrance means 70 is provided with a solid fragrance 100 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 to 5, fig. 3 is an internal structural view of the aromatherapy device 70 in the indoor unit of an air conditioner according to an embodiment of the present utility model, in which the lifting block 720 is in an extended position, fig. 4 is an internal structural view of the aromatherapy device 70 in the indoor unit of an air conditioner according to an embodiment of the present utility model, in which the lifting block 720 is in a retracted position, and fig. 5 is a schematic view of the lifting block 720 in the aromatherapy device 70 according to an embodiment of the present utility model.

Specifically, the aromatherapy device 70 may include a housing 710, a lifting block 720, a return spring 730, and a stopper 740, and the housing 710 has an upwardly open mounting chamber 712 therein. The lifting block 720 is disposed in the mounting cavity 712, a solid aromatherapy (not shown) is disposed on the top of the mounting cavity 712, and a limiting slot 722 is disposed on a side wall of the lifting block and configured to translate upward to an extended position or downward to a retracted position, so as to expose at least a portion of the solid aromatherapy in the extended position to the mounting cavity 712, and to entirely hide the solid aromatherapy in the mounting cavity 712 in the retracted position. A return spring 730 is disposed in the mounting cavity 712 and is configured to apply an elastic return force to the lifting block 720 that urges it to translate toward the extended position. The stopper rod 740 has a first end hinged to the housing 710 and a second end having a stopper protrusion 742 configured to extend the stopper protrusion 742 into the stopper groove 722 when the lifting block 720 is in the retracted position, so as to overcome the elastic restoring force, thereby locking the lifting block 720 in the retracted position.

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 this embodiment, the lifting block 720 is movable between an extended position and a retracted position, and when the lifting block 720 is operatively in the retracted position, the solid fragrance is retracted into the mounting chamber 712, effecting a relative seal, reducing fragrance emissions, i.e. turning off fragrance functions. When the lifting block 720 is operated in the extended position, the solid aromatherapy is extended into the installation cavity 712, so that the aroma emitted from the solid aromatherapy can be sufficiently emitted into the air to improve the smell of the indoor air, i.e., the aromatherapy function is turned on.

Further, the return spring 730 applies an elastic restoring force to the lifting block 720 that urges it to translate toward the extended position, that is, when the lifting block 720 is in the retracted position, the return spring 730 is in a compressed state and provides an upward elastic restoring force to the lifting block 720. Because the side wall of the lifting block 720 is further provided with the limit groove 722, the first end of the limit rod 740 is hinged to the housing 710, and the second end of the limit rod is provided with the limit protrusion 742, when the lifting block 720 is in the retracted position, the limit protrusion 742 extends into the limit groove 722, so that the limit rod 740 can provide a downward force for the lifting block 720 to overcome the elastic restoring force of the restoring spring 730 and stably lock the lifting block 720 in the retracted position.

Further, the limiting groove 722 is upwardly opened. The side wall of the lifting block 720 is also provided with at least one sliding groove 724, the upper end of the sliding groove 724 is connected to one side of the notch of the limiting groove 722, and the lower end of the sliding groove 724 is positioned right below the limiting groove 722. The fragrance means 70 is further configured to: the lifting block 720 is operable to continue to translate downwardly from the retracted position to disengage the limit projection 742 from the limit slot 722 and into the slide slot 724, such that the limit projection 742 gradually slides along the slide slot 724 to its lower end during upward translation of the lifting block 720 under the elastic restoring force.

In this embodiment, the limiting groove 722 is opened upwards, and when the lifting block 720 is in the retracted position, the return spring 730 applies an upward elastic restoring force to the lifting block 720, and the second end of the limiting rod 740 abuts against the bottom of the limiting groove 722 to counteract the elastic restoring force.

When the lifting block 720 is switched from the retracted position to the extended position, the lifting block 720 is first translated downward by the downward external force, so that the limit protrusion 742 is separated from the limit groove 722. Because the upper end of the sliding groove 724 is connected to one side of the notch of the limiting groove 722, and the first end of the limiting rod 740 is hinged to the housing 710, when the limiting protrusion 742 moves to the notch of the limiting groove 722, the limiting protrusion 742 at the second end of the limiting rod 740 can swing to deflect a little to easily enter the sliding groove 724, which can be understood as unlocking the lifting block 720.

In some embodiments, when the lifting block 720 is translated to the extended position, the limit protrusion 742 does not yet reach the downward end of the sliding groove 724, and the return spring 730 returns to the equilibrium state (the elastic restoring force is balanced with the gravity of solid fragrance or the like).

In other embodiments, as the lifting block 720 translates to the extended position, the stop tab 742 reaches the downward end of the slide channel 724 and the stop tab 742 engages the slide channel 724 to limit the lifting block 720 from continuing upward movement from the extended position. In this embodiment, the return spring 730 is further configured to be in a compressed state when the lifting block 720 is in the extended position, so as to generate an elastic pre-tightening force that makes the limit protrusion 742 collide with the intersection of the two limit grooves 722. The compressed state herein is understood to mean that the elastic restoring force is greater than the gravity force of solid aromatherapy or the like, that is, if the lifting block 720 is stably positioned at the extended position, a portion of downward pressure is applied to the lifting block 720, and this portion of downward pressure may be provided by the limit protrusions 742 of the limit lever 740. In other words, when the lifting block 720 translates to the extended position, the return spring 730 also provides a pre-tightening force for the lifting block 720, which is matched with the limiting protrusion 742, so that the overall structure is more stable.

Further, the number of the sliding grooves 724 is two, the upper ends of the two sliding grooves 724 are intersected above the notch of the limiting groove 722, and the lower ends of the two sliding grooves 724 are intersected below the limiting groove 722, that is, when the limiting protrusion 742 moves to the notch of the limiting groove 722, the sliding grooves 724 can be accessed from either side of the left side and the right side, so that the reliability of the system is ensured.

Further, each of the slide grooves 724 further includes a first segment 726 and a second segment 728, the beginning of the first segment 726 being the upper end of the slide groove 724, and the first segment 726 extending from the beginning thereof toward the lateral direction away from the slide groove 724 and downward, the beginning of the second segment 728 being connected to the end of the first segment 726 and extending toward the lateral direction near the slide groove 724 and downward.

In some embodiments, a guide protrusion 750 protruding toward the limit groove 722 is formed at the intersection of the upper ends of the two sliding grooves 724, and two guide surfaces 752 are provided on two lateral sides of the guide protrusion 750, and each guide surface 752 corresponds to one sliding groove 724, so as to guide the limit protrusion 742 into the corresponding sliding groove 724.

When the lifting block 720 continues to move downward from the retracted position by the external force, the limit projection 742 of the limit lever 740 may first contact one of the guide surfaces 752, and the guide surface 752 may guide the limit projection 742 to the slide groove 724 so as to be smoother when unlocked.

In some embodiments, return spring 730 is a compression spring having a first end connected to the bottom of lifting block 720 and a second end connected to the bottom wall of mounting cavity 712.

The number of the return springs 730 is plural, and the forces applied to the lifting blocks 720 by the plural return springs 730 keep the lifting blocks 720 balanced in the horizontal direction, that is, the resultant force of the forces applied to the lifting blocks 720 by the plural return springs 730 is in the widthwise center of the lifting blocks 720 to secure the balancing of the lifting blocks 720 in the horizontal direction.

In some embodiments, the fragrance means 70 further comprises a fragrance cover 760, the fragrance cover 760 is fastened to the top of the lifting block 720 to protect the solid fragrance, and the peripheral wall and/or the top wall of the fragrance cover 760 are provided with air flow holes. When the lifting block 720 is in the extended position, the solid fragrance extends out of the mounting cavity 712, which is capable of emitting fragrance to the indoor environment through the airflow aperture.

When the lifting block 720 is in the retracted position, the top wall of the fragrance cover 760 is flush with the top wall of the housing 710, which is both dust-proof and aesthetically pleasing. In some preferred embodiments, the peripheral wall of the fragrance housing 760 is provided with air flow holes, and the top wall thereof is not provided with air flow holes, so that dust prevention can be further achieved.

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.
