With the development of the times and the progress of technology, users not only expect faster cooling and heating speeds of air conditioners, but also pay more attention to the comfort performance of the air conditioners.

An indoor unit of an air conditioner, particularly an indoor unit of a floor air conditioner, is generally provided with a plurality of swing vanes at an air outlet to guide the left and right air outlet directions. However, the traditional swing blade can only swing air left and right, and cannot meet the air supply experience of natural wind without wind sensation.

Some prior art schemes arrange circular micropores on the swinging blades, can realize non-wind-sense air supply to a certain extent, but the dense hole opening mode can bring great air volume loss to the air flow, and only make the air volume become smaller, the wind sense is lighter, but there is not good natural wind effect.

SUMMERY OF THE UTILITY MODEL

The present invention aims to provide an air conditioner indoor unit and an air guide assembly thereof, which overcome the above problems or at least partially solve the above problems.

The utility model aims to improve the no-wind effect of air supply airflow of an air conditioner so as to enable the air conditioner to be closer to natural wind.

In one aspect, the present invention provides an air guide assembly for an indoor unit of an air conditioner, configured to be installed at an air outlet of the indoor unit of the air conditioner to guide an air outlet direction of the air outlet, wherein,

the air guide assembly comprises a plurality of swing blades, each swing blade can be rotatably installed at the air outlet around a respective rotation axis, and a plurality of notches are formed in the edges of at least two adjacent swing blades, so that when the swing blades rotate to a coplanar state, the notches of the two adjacent swing blades are opposite to one another to be spliced into a plurality of air dispersing openings.

Optionally, at least part of the air-dispersing openings are triangular air-dispersing openings.

Optionally, at least a part of the notch formed in one edge of at least one of the swing blades is a triangular notch, and at least a part of the notch formed in the edge of another swing blade adjacent to the triangular notch is a trapezoidal notch with an open top edge, so that when the two swing blades rotate to a coplanar state, the triangular notch and the trapezoidal notch are relatively spliced to form the triangular air diffuser.

Optionally, a plurality of the triangular notches and a plurality of the trapezoidal notches are respectively formed on two opposite side edges of each swing blade.

Optionally, the rotatable range of each of the pendulum blades is greater than 180 ° to allow both the triangular notch of each pendulum blade to oppose the trapezoidal notch of its adjacent pendulum blade and the trapezoidal notch of that pendulum blade to oppose the triangular notch of that adjacent pendulum blade.

Optionally, each of the swing blades is in the shape of a long strip extending in a vertical direction, a rotation axis of the swing blade is parallel to a length direction of the swing blade, and the swing blades are arranged in a transverse direction;

one long edge of each swinging blade is provided with a plurality of triangular notches arranged along the length direction of the swinging blade, and the other long edge of each swinging blade is provided with a plurality of trapezoidal notches arranged along the length direction of the swinging blade.

Optionally, when two adjacent swinging blades are in a coplanar state, the ratio of the width of the gap between the two swinging blades to the height of the triangular air diffuser is less than 0.07.

Optionally, the triangular gap is an equilateral triangle, and the trapezoidal gap is an isosceles trapezoid, so that the triangular air diffuser is an isosceles triangle.

Optionally, the ratio of the height of the triangular notch to the height of the trapezoidal notch is between 0.9 and 1.1.

In another aspect, the present invention provides an indoor unit of an air conditioner, including:

a shell which is provided with an air outlet; and

at least one wind guide assembly as described above, installed at the air outlet to guide the air outlet direction of the air outlet.

The air guide assembly for the indoor unit of the air conditioner does not have the advantages that the micro-holes are formed in each swing blade to obtain the breeze effect, so that the air guide assembly can avoid great air volume loss of air supply airflow caused by dense hole opening of the swing blades. The utility model ensures that the edges of the swing blades are respectively provided with the notches, and when the adjacent swing blades are in a coplanar state (when all the swing blades are in the coplanar state, each swing blade of the air outlet is closed), the notches of the adjacent swing blades are oppositely spliced to form the air dispersing port, thereby realizing good breeze effect. When the swinging blade rotates to the swinging position, the notch at the edge of the swinging blade makes the edge of the swinging blade uneven and has a scattering effect on the flowing air flow, so that the air flow is more natural and comfortable. The mode of opening the notch can not bring too large energy loss to the air current, and the strength of the swing blade can be ensured, so that the reliability is better.

Furthermore, the air guide assembly of the utility model enables the air diffuser to be triangular, and according to the aerodynamic principle, when air flows pass through the triangular air diffuser, the flow velocity is inevitably lower. The pressure loss of the bottom edge area (at the trapezoid notch) of the triangular air diffuser is less, the flow speed is slow and the turbulent kinetic energy is small; the top edge area (at the triangular notch) has large pressure loss, high flow speed and large turbulent kinetic energy. Under the comprehensive action, the stronger turbulent kinetic energy of the airflow in the top edge area can deviate to the bottom edge area, and rhythmic disturbance of a space flow field is caused in the process of continuously mixing the airflow with the airflow in the bottom edge area, so that soft, comfortable and natural non-wind feeling experience can be generated.

Furthermore, in the air guide assembly, the rotatable range of each swing blade is larger than 180 degrees, and when the swing blade A is in a closed state (coplanar with the adjacent swing blade B), the triangular notch of the swing blade A is opposite to the trapezoidal notch of the swing blade B. And when the two swing blades rotate 180 degrees, the trapezoidal notch of the swing blade A is opposite to the triangular notch of the swing blade B. Thus, two matching modes are formed, and the air supply mode is more diversified.

The above and other objects, advantages and features of the present invention will become more apparent to those skilled in the art from the following detailed description of specific embodiments thereof taken in conjunction with the accompanying drawings.

The utility model provides an air guide assembly for an indoor unit of an air conditioner and the indoor unit of the air conditioner. An indoor unit of an air conditioner is an indoor part of the air conditioner for conditioning indoor air, such as cooling/heating, dehumidifying, introducing fresh air, and the like. The air guide assembly is used for being installed at an air outlet 12 of a shell 10 of the air conditioning indoor unit so as to guide the air outlet direction of the air outlet 12.

Fig. 1 is a schematic structural view of an indoor unit of an air conditioner according to an embodiment of the present invention; fig. 2 is a schematic sectional view of the air conditioning indoor unit shown in fig. 1; FIG. 3 is an enlarged view at A of FIG. 1; fig. 4 is a schematic view of the air conditioning indoor unit shown in fig. 1 when the swing vanes 50 are in a coplanar state; fig. 5 is a schematic sectional view of the air conditioning indoor unit shown in fig. 4; fig. 6 is an enlarged view of fig. 4 at B.

As shown in fig. 1 to 6, the wind guiding assembly of the embodiment of the utility model may generally include a plurality of swinging blades 50. Each swing vane 50 is rotatably mounted at the outlet 12 about a respective axis. That is, each of the swing vanes 50 rotates about its own axis, rather than all of the swing vanes 50 rotating about the same axis. Of course, the swinging blades 50 can be rotated synchronously by the moving mechanism, so as to guide the air flow of the air outlet 12 to the same direction at the same time. Synchronous motion mechanisms are very common in the art and are not described in detail herein. For example, as shown in fig. 2, the plurality of swing blades 50 are in a state of guiding the wind toward the front side of the air conditioning indoor unit together, and in fig. 5, the plurality of swing blades 50 are rotated together to a coplanar state, or a closed state, to close the outlet 12.

Each swing blade 50 of the air guide assembly can be directly and rotatably mounted on the casing 10 of the indoor unit of the air conditioner. Of course, the wind guide assembly may include an outer frame, each of the swing blades 50 may be directly rotatably mounted to the outer frame, and the outer frame may be mounted to the housing 10.

As shown in fig. 2 and 5, a plurality of notches are formed on the edges of at least two adjacent swing vanes 50. When the swing blades 50 rotate to the coplanar state, the notches of the two adjacent swing blades 50 are opposite to each other one by one so as to splice into a plurality of air-dispersing openings.

For example, at least adjacent swing blades a and B exist, specifically, a first edge of the swing blade a is adjacent to a second edge of the swing blade B, at least the first edge of the swing blade a is provided with a plurality of notches, and the second edge of the swing blade B is provided with a plurality of notches. When the swing blade A and the swing blade B rotate to the coplanar state, the notches of the swing blade A are opposite to the notches of the swing blade B one by one, and a plurality of air dispersing openings are formed by splicing. For example, some (at least two) of the flaps 50 of the air guide assembly may be notched, while the other flaps 50 are not notched. Of course, all of the swinging blades 50 may be notched. Fig. 1 to 6 show an embodiment in which all the swing vanes 50 are notched.

The air guide assembly for the indoor unit of the air conditioner in the embodiment of the utility model does not provide a micro-hole on each swinging blade 50 to obtain a breeze effect. In some prior art schemes, a plurality of micropores are densely formed in the swinging blade 50 to obtain some breeze effects. However, the inventor finds that the proposal brings great air volume loss to the air supply flow, and only the air volume is smaller, the wind feeling is lighter, but the effect of natural wind is not good. In the first embodiment of the present invention, especially, the edges of the swing blades 50 are respectively provided with the notches, and when the adjacent swing blades 50 are in the coplanar state (when all the swing blades 50 are in the coplanar state, the swing blades 50 of the air outlet 12 are closed), the notches of the adjacent swing blades 50 are relatively spliced to form the air diffuser, so as to achieve a good breeze effect. When the swing blade 50 rotates to the swing position, the edge of the swing blade 50 is uneven due to the notch at the edge, and the flowing air flow is dispersed, so that the air flow is more natural and comfortable. The mode of opening the notch can not bring too large energy loss to the air current, and the strength of the swing blade 50 can be ensured, so that the reliability is better.

In some embodiments of the utility model, at least some of the dispersion openings are triangular dispersion openings 501. At least partially refers to a portion or all. For example, in the embodiment shown in fig. 1 to 6, all the air diffusing openings are triangular air diffusing openings 501, please refer to fig. 3 and 6. Of course, one dispersing air port can be a triangular dispersing air port, and the other dispersing air ports can be other dispersing air ports, which is easy to understand and is not described again.

The inventors have found that, according to aerodynamic principles, when there is an air flow through the triangular diffuser 501, the flow velocity is necessarily lower. The bottom edge area (the trapezoidal notch 51) of the triangular air diffuser 501 has less pressure loss, low flow speed and small turbulent kinetic energy; the top edge area (at the triangular notch 52) has large pressure loss, fast flow velocity and large turbulence energy. Under the comprehensive action, the stronger turbulent kinetic energy of the airflow in the top edge area can deviate to the bottom edge area, and rhythmic disturbance of a space flow field is caused in the process of continuously mixing the airflow with the airflow in the bottom edge area, so that soft, comfortable and natural non-wind feeling experience can be generated.

In some embodiments, referring to fig. 3 and fig. 6, at least a part of the notches (referring to a part of the notches or all of the notches) formed in one edge of at least one of the flaps 50 is a triangular notch 52, and at least a part of the notches (referring to a part of the notches or all of the notches) formed in an edge of another flap 50 adjacent to the one edge is a trapezoidal notch 51 with an open top side, so that when the two flaps 50 rotate to a coplanar state, the triangular notch 52 and the trapezoidal notch 51 are spliced into a triangular air diffuser 501.

It should be emphasized that the "triangular" air diffuser, "triangular" notch and "trapezoidal" notch of the embodiments of the present invention are not limited to the exact mathematical triangle or trapezoid, but only approximately triangle or trapezoid, for example, each side of the notch may be a straight side, or a curved side with a certain curvature, and the corner may be a sharp corner or a rounded corner.

Furthermore, a plurality of triangular notches 52 and a plurality of trapezoidal notches 51 can be respectively formed on two opposite side edges of each swing blade 50. In this way, the central flap 50 and the adjacent flaps 50 on both sides can form the triangular air diffuser 501.

In some embodiments, as shown in fig. 1 to 6, each of the swing blades 50 has a long plate shape extending in a vertical direction, a rotation axis thereof is parallel to a length direction thereof, and the swing blades 50 are arranged in a lateral direction. The air guide assembly formed by the vertically long strip-shaped swing blade 50 is particularly suitable for an air conditioner indoor unit with the air outlet 12 in a vertical strip shape, such as an air conditioner cabinet or a vertical wall hanging machine. In other embodiments, each of the swinging blades 50 may also extend in a horizontal direction, or extend in other directions, so that the swinging blades can be applied to a conventional horizontal-strip-shaped wall-mounted air conditioner indoor unit, which is not described herein again.

For the vertically extending swing blade solution, one long side of each swing blade 50 (two long sides of the swing blade 50 in the width direction are longer, and referred to as two long sides) is provided with a plurality of triangular notches 52 arranged along the length direction, and the other long side is provided with a plurality of trapezoidal notches 51 arranged along the length direction. Thus, when each of the flaps 50 rotates to the coplanar state, as shown in fig. 6, a plurality of rows of triangular air-dispersing openings 501 are formed, wherein the number of the rows is the total number of the flaps 50 minus one.

The inventor finds that factors such as the shape and the size of the triangular air diffuser 501 have certain influence on the airflow breeze effect. To this end, the inventors have computationally determined some preferred schemes. Specifically, when two adjacent swing blades 50 are in a coplanar state, the ratio of the gap width between the two swing blades to the height of the triangular air diffuser 501 is less than 0.07, preferably less than 0.06, so that the gap width is smaller, and the triangular air diffuser 501 is more complete, so that the disturbance effect is better. And, it is preferable to make the triangular notch 52 an equilateral triangle and the trapezoidal notch 51 an isosceles trapezoid, so that the triangular air diffuser 501 is an isosceles triangle, so that the air flow of the triangular notch 52 is exactly aligned with the air flow of the trapezoidal notch 51, so as to generate a stronger mixing and disturbing effect. It is also possible to make the ratio of the height of the triangular notch 52 to the height of the trapezoidal notch 51 between 0.9 and 1.1, more preferably between 0.95 and 1.05, for example 1, to control the ratio of the air flow throughput of the two to achieve the optimum mixing and turbulence effect.

Fig. 7 is a schematic view of the swing vanes 50 shown in fig. 6 after they are rotated by 180 °.

In some embodiments, the rotatable range of each pendulum blade 50 can be made greater than 180 ° to allow both the triangular notch 52 of each pendulum blade 50 to oppose the trapezoidal notch 51 of its adjacent pendulum blade 50 and the trapezoidal notch 51 of that pendulum blade 50 to oppose the triangular notch 52 of that adjacent pendulum blade 50.

Specifically, as shown in fig. 6, the triangular notches 52 of the three flaps 50 are all located on the right side, and the trapezoidal notches 51 are located on the left side, so as to form two rows of triangular air-diffusing openings 501 with the tips facing to the left. When the swing blades 50 rotate 180 °, the state shown in fig. 7 is reached, so that the triangular notches 52 of the three swing blades 50 are all located on the left side, and the trapezoidal notches 51 are located on the right side, so as to form two rows of triangular air dispersing openings 501 with the tips facing right. The different orientation of the tip of the triangular air diffuser 501 inevitably results in different air outlet directions. Therefore, the embodiment of the present invention can obtain different breeze effects by rotating the swing vane 50 by 180 °.

Of course, in order to normally close the air outlet 12 after the swing vane 50 rotates 180 °, the rotation axis of the swing vane 50 may be located at the center of the width direction.

The embodiment of the utility model also provides an air conditioner indoor unit. The air conditioning indoor unit generally comprises a casing 10 and at least one air guide assembly as described in any of the above embodiments. The casing 10 is provided with an air outlet for blowing air flow (cold air, hot air or fresh air) in the casing 10 to the indoor environment to adjust the indoor environment, and the air guide assembly is installed at the air outlet 12 to guide the air outlet direction of the air outlet 12.

As shown in fig. 1 to 4, the indoor unit of an air conditioner may be a cabinet air conditioner, which includes a casing 10. The housing 10 is an upright elongated shape. The casing 10 defines an accommodation space for accommodating components of the air conditioning indoor unit. Two air outlets 12 arranged up and down are opened on the front side of the housing 10, and each air outlet 12 is provided with an air guide device.

As shown in fig. 2, the indoor unit of the air conditioner may be an indoor portion of a split type room air conditioner that performs cooling/heating using a vapor compression refrigeration cycle system. The inside of the case 10 is provided with a heat exchanger 30 and a fan 40. The heat exchanger 30, the throttle device, and a compressor, a condenser, and other refrigeration components disposed outside the air conditioning chamber are connected by pipelines to form a vapor compression refrigeration cycle system. Under the action of the fan 40, the indoor air enters the inside of the casing 10 through the air inlet formed in the casing 10, after the forced convection heat exchange with the heat exchanger 30 is completed, forms heat exchange air and enters the air duct 20, and then is blown to the indoor environment through the air outlet 12, and is guided in the direction of receiving the plurality of swing blades 50 at the air outlet 12. The fan 40 is preferably a cross flow fan having an axis parallel to the length of the housing 10, and is disposed at the inlet of the air duct 20.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the utility model have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the utility model may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the utility model. Accordingly, the scope of the utility model should be understood and interpreted to cover all such other variations or modifications.
