The embodiment of the invention provides a vertical air conditioner indoor unit. An indoor unit of a floor type air conditioner is an indoor part of the air conditioner for conditioning indoor air, such as cooling/heating, dehumidifying, purifying, introducing fresh air, and the like.

Fig. 1 is a schematic structural view of a vertical air conditioner indoor unit according to an embodiment of the present invention; fig. 2 is an enlarged cross-sectional view C-C of the indoor unit of the air conditioner shown in fig. 1; fig. 3 is an enlarged view of the air guide duct 20 in fig. 2.

As shown in fig. 1 and 2, the indoor unit of a vertical air conditioner according to an embodiment of the present invention may generally include a cabinet 10, two air ducts 60, and two air ducts 20.

The housing 10 is formed with two air outlets 12 arranged transversely therealong for supplying air to the indoor environment. The front of the indoor unit of the upright air conditioner, which faces the user mainly, is the front, thereby defining the front-rear direction of the cabinet 10. The left-right direction perpendicular to the front-rear direction constitutes the lateral direction of the casing 10, "front-rear" and "lateral" have been indicated in fig. 2. The cabinet 10 defines an accommodation space for accommodating main components of the indoor unit of the floor type air conditioner, and the interior of the cabinet 10 forms an air flow for conditioning an indoor environment, such as cool air, warm air, fresh air flow, and the like.

Two air ducts 60 are disposed in the casing 10 and arranged along the transverse direction of the casing 10, and an outlet of each air duct 60 communicates with one air outlet 12. Specifically, each air duct 60 may be defined by first and

second duct walls

61, 62 that are spaced apart. Further, the first and second

air duct walls

61 and 62 may be a part of the cabinet 10.

Each air duct 20 is erected at one air outlet 12. Each air guide duct 20 is cylindrical, and the axial direction thereof is parallel to the vertical direction. The peripheral wall of each air duct 20 includes an air guiding section 21 and a ventilation section 22 arranged along the circumferential direction thereof, so as to allow the outlet air flow at the air outlet 12 to enter the inside of the air duct 20 through a partial area of the air guiding section 22, to be guided by the inner wall of the air guiding section 21, and to be blown to the indoor environment through the rest area of the air guiding section 22, and the air duct 20 is configured to be rotatable around the vertical axis x to adjust the outlet air direction thereof.

In the vertical air conditioner indoor unit of the embodiment of the invention, the air duct 20 is cylindrical, and compared with the traditional air deflector, the structure is more novel and unique. The circumferential wall of the air guide duct 20 includes an air guide stage 21 and a ventilation stage 22 arranged along the circumferential direction thereof. When the indoor unit of the floor air conditioner is operated, the outlet airflow firstly enters the air guide duct 20 through a part of the area of the air guide section 22, then is guided by the inner wall 211 of the air guide section 21, and then is blown to the indoor environment through the rest area of the air guide section 22, as shown in fig. 2. In the process, the air outlet flow passes through the ventilation section 22 twice and is scattered twice, and the air guide cylinder 20 is internally circularly rotated once, so that the softness of the air flow is further enhanced, the noise of the air flow is lower, and the wind sensation is softer. The vertical air conditioner indoor unit creates a quiet and comfortable air supply environment, so that a human body feels more comfortable.

Of course, the air guide duct 20 may also comprise two end walls (not shown) which together with the circumferential wall define the inner cavity of the air guide duct 20. The indoor unit of the upright air conditioner may include a motor having a rotation shaft connected to one of the end walls for driving the air guide duct 20 to rotate about the x-axis. The motor may be a stepper motor. The motor can be electrically connected with a controller of the vertical air conditioner indoor unit so as to be controlled by the controller.

In some embodiments, each air duct 20 is configured to: rotate towards a direction all the time when adjusting the air-out direction. That is, the air duct 20 can be rotated to any air outlet angle only by rotating the air duct 20 in the clockwise direction or the counterclockwise direction all the time. The controller does not need to control the positive and negative rotation of the motor, and the structure and the control logic of the motor are simplified. Of course, in alternative embodiments, the air guide duct 20 may be configured to rotate in both forward and reverse directions.

In the prior art, a plurality of micro-holes are formed in a casing or an air deflector so as to realize the micro-hole air supply effect. However, in these proposals, the direction of the air flow after being blown out is not guided, and the directivity of the air outlet is not good. The air duct 20 in the embodiment of the present invention not only softens the outlet airflow, but also guides the air particularly by using the inner wall 211 of the air guiding section 21, and the air guiding section 21 performs the function of a conventional air guiding plate, so that the directivity of the outlet airflow is stronger. The air duct 20 of the invention gives consideration to both the direction guiding of the air outlet flow and the breeze effect, and has simple and ingenious structure.

In some embodiments of the present invention, as shown in fig. 3, the ventilation section 22 may be a plate shape with a plurality of air dispersing holes 222. Specifically, each of the air dispersing holes 222 may be a long hole having a length direction parallel to the length direction of the air guiding duct 20, and the air dispersing holes 222 may be sequentially arranged at intervals in the circumferential direction of the air guiding duct 20. Compared with round holes or square holes arranged in a matrix manner, the ventilation area of the strip holes is larger, so that unsmooth air outlet caused by too small ventilation area is avoided, and the refrigerating/heating efficiency of the vertical air conditioner indoor unit is influenced. In addition, both ends of each air dispersing hole 222 in the length direction may extend to positions adjacent to both ends of the air guide duct 20 in the length direction, respectively, so that the length thereof can cover the entire length direction of the outlet 12.

In some embodiments, as shown in fig. 3, the width of any wind dispersing hole 222 may be m, and the width of the solid portion between the wind dispersing hole 222 and any adjacent wind dispersing hole 222 is n; satisfies the following conditions: m/n is more than or equal to 1.9 and less than or equal to 2.1. Preferably, 1.95. ltoreq. m/n.ltoreq.2.05, for example, 2. Therefore, the balance between smoothness and softness of air outlet can be realized. The width m of each air dispersing hole 222 may be the same or different. The width n of each solid portion may be the same or different. Preferably, the width m of each air dispersing hole 222 is the same, and the width n of each solid portion is the same.

In some embodiments, as shown in fig. 3, the inner wall 211 of the air guiding section 21 is a concave curved surface with a generatrix parallel to the length direction of the air guiding duct 20. So set up, can make inner wall 211 can guide the wind better to for the turning of air current is more gentle. For example, the inner wall 211 of the air guiding section 21 may be an inner concave arc surface whose central axis is parallel to the length direction of the air guiding duct 20. Further, the central axis of the air guide duct may be coincident with the rotation axis x of the air guide duct 20.

In some embodiments, as shown in fig. 2-4, the air guide duct 20 may be cylindrical, with its axis of rotation coinciding with the central axis of the cylinder. The central angle a of the outer contour of the air guide segment 21 ranges from 110 ° to 130 °, and is, for example, 120 °.

In other embodiments, the air duct 20 may have a polygonal prism shape, and the rotation axis of the air duct coincides with the central axis of the polygonal prism. Of course, the present embodiment does not strictly limit the air guiding duct 20 to be a geometrical polygonal prism, and each side surface thereof is not necessarily a plane, and may also be a concave or convex curved surface, as long as the overall polygonal prism is substantially the same, which falls within the protection scope of the present invention. The air duct 20 may be in a regular hexagonal prism shape, two of the six outer side surfaces of the air duct form the outer surface of the air guiding section 21, and the inner side surfaces corresponding to the two outer side surfaces form an integral arc surface to form the inner wall 211 of the air guiding section 21.

In some embodiments of the present invention, the operation of each air duct 20 is independently controlled so as to independently adjust the air supply direction of the corresponding air outlet 12. As shown in fig. 2, both of the outlets 12 may be opened diagonally forward, and the opening directions may be away from each other in the lateral direction of the casing 10. That is, the left outlet port 12 is opened to the front left, and the right outlet port 12 is opened to the front right. The opening directions of the two air outlets 12 are designed in this embodiment, so that the air outlet direction of each air outlet 12 is adjustable between an oblique front air supply direction and an oblique rear air supply direction. In the above-mentioned oblique forward blowing direction, the air flow gradually approaches the oblique forward direction right in front of the lateral center of the casing 10, for example, to the left air outlet 12, the air is blown to the right forward direction by the oblique forward blowing fingers, as shown in fig. 5. In the aforementioned oblique rear blowing direction, the airflow is laterally away from the casing 10 and gradually flows obliquely rearward, as shown in fig. 6. Therefore, the range of the air outlet angle of each air outlet 12 in the embodiment of the present invention is wider.

Because the range of the air outlet angles of the two air outlets 12 is larger in the embodiment of the invention, the combination of various air supply angles can be formed by independently adjusting the air supply angles of the two air outlets 12, so that the indoor unit of the vertical air conditioner has more diversified air supply modes.

For example, as shown in fig. 2, the indoor unit of the floor standing air conditioner may be operated in the front blowing mode. Specifically, both air ducts 20 supply air to the front, and the outlet air flows of both air outlets 12 flow forward.

As shown in fig. 4, the indoor unit of the floor air conditioner may be operated in the wrap-around blowing mode. Specifically, the two air ducts 20 are both blown out obliquely forward and are separated from each other in the air-out direction, so that the two airflows flow forward on the two sides of the casing 10.

As shown in fig. 5, the indoor unit of the floor air conditioner may be operated in the unified blowing mode. Specifically, the two air ducts 20 are all supplied with air to the oblique front, so that the air outlet flows of the two air outlets 12 gradually approach to each other and converge in front of the casing 10, so that the wind power is stronger, and the air supply distance is longer.

As shown in fig. 6, the indoor unit of the floor air conditioner may be operated in the soft air supply mode. Specifically, both air ducts 20 are used for blowing air in a direction transversely far away from the casing 10, so that the air flow is far away from the front of the casing 10, and the two air flows are diffused to other indoor areas along the wall, so that the temperature of the indoor environment is reduced/increased in a softer manner, and people feel more comfortable.

Fig. 4 to 6 illustrate a mode in which both the outlet vents 12 are opened. As shown in fig. 7 or 8, only one outlet 12 may be opened, and the other outlet 12 may be closed by the air duct 20.

As shown in fig. 9, when the indoor unit of the vertical air conditioner is in a shutdown state or other states not requiring air supply, the air guiding barrel 20 may be rotated to an angle that the air guiding section 21 faces outward, so as to seal the air outlet 12 with the air guiding section 21. So as to prevent impurities such as dust from entering the interior of the casing 10 through the outlet 12.

In some embodiments, the vertical air conditioner indoor unit is provided with a sensor capable of sensing the position of a human body, and the sensor is electrically connected with a controller of the air conditioner, so that the controller can automatically select an air supply mode according to the distance between the human body and the vertical air conditioner indoor unit.

Specifically, when the sensor detects that the person is far away from the indoor unit of the vertical air conditioner, the controller automatically adjusts the angle of the air duct 20, so that the indoor unit of the vertical air conditioner operates in the aggregated air supply mode.

When the sensor senses that a person approaches the indoor unit of the vertical air conditioner from far to near, the controller automatically adjusts the angle of the air duct 20, so that the indoor unit of the vertical air conditioner runs in a front air supply mode. The airflow is sent out straightly and is not converged any more, the wind speed is reduced, and the discomfort caused by cold air blowing on a human body is avoided;

when the sensor senses that a person is positioned right in front of the vertical air conditioner indoor unit, the controller automatically adjusts the angle of the air guide cylinder 20, so that the vertical air conditioner indoor unit operates in an encircling air supply mode, air flow is exhausted from two sides of the casing at the moment, the air flowing efficiency of the space is increased, and the comfort of the person is increased.

When the sensor senses that the person is in a sleeping or quiet state, the angle of the air duct 20 is automatically adjusted, a soft air supply mode is entered, air flow supplies air through the strip-shaped slit holes in the air duct 20 twice, air speed is low, noise is low, wind sense is soft, air supply is performed from two sides slowly, and a quiet and comfortable environment is created.

When the sensor senses that the person is positioned at the left/right front of the vertical air conditioner indoor unit, the air outlet 12 at the right/left side is closed, and air is guided only by the air guide cylinder 20 at the left/right side.

As shown in fig. 2, in the embodiment of the present invention, the indoor unit of the vertical air conditioner may be an indoor part of a split-type room air conditioner that performs cooling/heating using a vapor compression refrigeration cycle system. The inside of the cabinet 10 is also provided with a heat exchanger 30. The heat exchanger 30, the throttle device, and a compressor, a condenser, and other refrigeration components disposed in the air conditioning outdoor unit are connected by pipelines to form a vapor compression refrigeration cycle system. Under the action of the fan 40, the indoor air enters the interior of the casing 10 through an air inlet (not shown, which may be disposed on the rear wall or the lateral two side walls of the casing) of the casing 10, and after completing the forced convection heat exchange with the heat exchanger 30, forms heat exchange air, which is guided to the air outlet 12 by the air duct 60 and then blown to the indoor environment, thereby completing the conditioning of the indoor ambient air.
