Then, the outside air is sucked through the suction grille 7, the orifice piece 5, the suction guide 4, and the fan 2 by the negative pressure inside the case 1. The heat-exchanged air passing through the heat exchanger is discharged to the outside through the discharge port of the drain pan (3) and the front panel (6).

2 is a plan view of the air conditioner according to the present embodiment, showing a front panel of the air conditioner.

Referring to FIG. 2, a discharge port 9 is formed at four corners of the front panel 6. A vane 8 for regulating the flow of the air discharged through the discharge port 9 is provided in the open portion of the discharge port 9. The setting angle of the vane is automatically adjusted by a motor installed on one side of the vane (8).

The front panel 6 is provided in a rectangular shape and the discharge port 9, the vane 8, and the vane motor (see 83 in FIG. 4) are separately installed at corner portions of the front panel 6 . Therefore, the flow directions of the air discharged through the respective discharge ports 9 can be individually adjusted.

In this embodiment, the direction of the air discharged through the discharge port 9 can be adjusted not only in the vertical direction but also in the left and right direction by the vane 8, The related structure and method will be described in detail.

FIG. 3 is a side sectional view showing the inside of the discharge port in the first embodiment, and FIG. 4 is a perspective view of the vane assembly in the first embodiment.

3 and 4, the front panel 6 and the drain pan 4 are provided with a discharge port 9 through which conditioned air is discharged. A vane 8 is provided in the discharge port 9 and a louver 81 is provided on an upper surface of the vane 8. The discharge air can be discharged in a controlled manner in the vertical direction by the vane 8 and the discharged air can be discharged in the left and right direction by the louver 81. [ It will be easily understood that the louver 81 and the vane 8 can be automatically adjusted in their angles of rotation by respective motors.

Herein, in the technical field for controlling the air direction of the air conditioner, it is generally called a vane to adjust the discharge direction of the air in the up-and-down direction, and the discharge direction of the air in the left- In the following description.

Referring to FIG. 4, the structure and the manner in which the vane and the louver can be operated can be understood more clearly. First, ribs 90 are provided at both ends of the vane 8 for switching the flow direction of air upward and downward. The driving shaft of the vane motor 83 is connected to either one of the ribs 90, so that the vane 8 can be adjusted up and down at an appropriate angle.

At least one or more, preferably a plurality of louvers 81 are supported on the upper surface of the vane 83. The louver 81 is rotatably supported on the upper surface of the vane 8 by a pivot hinge 85. A slot 84 is formed at one side of the louver 81 and an operation bar 89 is inserted into the slot 84. The louver 81 can be moved in the lateral direction about the pivot hinge 85 by the operating portion 89. A stopper 95 is provided at a position of the operation bar 89 in contact with the louver 81 so that the louver 81 can move in the left and right direction by the operation bar 89. [

The louver 81 may be provided so that the discharge side thereof is wider than the inlet side so that the air discharged to the outside through the louver 81 is smoothly discharged along the outer surface of the louver 81. [

A rack 88 is provided at one end of the operating bar 89 and a pinion 87 is engaged with the rack 88. The pinion 87 is engaged with the drive shaft of the louver motor 86, .

In order to prevent the operation bar 89 and the louver 81 from interfering with each other when the vane 8 rotates up and down, when the operation bar 89 is centered on the rib 90, And is provided on the same axis in the left-right direction with the vane motor 83. The movement of the vane 8 in the up and down direction and the movement of the operation bar 89 in the left and right directions can be performed independently of each other.

5 is a diagram showing a state in which the air conditioner according to the present embodiment is installed.

Referring to FIG. 5, when the ceiling air conditioner 10 is installed on the ceiling, since the ceiling air conditioner is provided in a quadrangular shape, there is a problem that air can not be properly blown into the corner of the air conditioner. In other words, since the air discharged through the four sides of the ceiling-mounted air conditioning apparatus is blown only in the discharge direction, the user located at the corner portion can hardly sense the air flow of the air. Each of the corner portions is indicated by reference numerals 11, 12, 13, and 14.

Therefore, when the user is positioned at the corner portion, it is necessary to blow air ventilated to the corresponding position. Then, the user can control the air conditioner to blow air in the corresponding direction.

More specifically, a screen as shown in Fig. 5 may be displayed on the operation unit of the air conditioner, and air may be discharged to the corresponding portion. Then, the corner air conditioning mode in which air is ventilated in the indicated direction is performed.

Fig. 6 is a flowchart for explaining the control method of the air conditioner in which the corner air-conditioning mode is performed. The corner air-conditioning mode will be described in more detail with reference to Fig.

First, the user selects a position of a specific corner portion to which the air is to be blown (S1), referring to the screen or other instruction means shown in FIG. 5 displayed on the display window of the device exemplified by the remote controller. Then, in order to blow air ventilated to the selected position, the louver 81 is controlled (S2).

The process of controlling the louver 81 will be described in more detail with reference to FIG.

For example, if it is instructed that the air ventilated to the corner indicated by 11 is blown, the louver 81 lying between 11 and 14 is deflected to the right to blow air to the right. Then, the louver 81 placed between No. 12 and No. 11 is deflected downward so that air is blown downward.

According to the position where the louver is placed, the air that has been air-conditioned can also be blown to the corner 11.

On the other hand, even when the louver 81 is being rotated in the left-right direction, the up-and-down rotation of the vane 8 does not cause interference with the louver. Therefore, the flow direction of the air discharged in the up-and-down direction can also be precisely operated as desired by the user. The reason for such an operation has already been explained.

Since the corner air conditioning mode as described can be performed, it is expected that an old problem that has been pointed out as a root cause of the ceiling air conditioner can be solved.

The first embodiment described above discloses an idea that the user can more conveniently use the air conditioner by switching the air discharge direction to be cooperated in accordance with a user's desired situation. However, installing a louver capable of operating separately can be used optimally in the case of an expensive air conditioner, but even in the case of a low-cost model, performing such a corner air conditioning mode is preferable because it causes a considerable increase in material cost Can not.

≪ Embodiment 2 >

The second embodiment of the present invention overcomes the problem of the first embodiment described above and provides a louver which is manually operated instead of a louver that is automatically operated. Therefore, the description of the first embodiment will be omitted for the description of the part without any specific explanation.

7 is a perspective view showing a vane and its adjacent structure in the air conditioner according to the second embodiment.

Referring to Fig. 7, the vane 8, the rib 90, and the vane motor 83 are installed as in the first embodiment. The louver 81 is also mounted on the upper surface of the vane 8 by the pivot hinge 85. The louver 81 is mounted on the upper surface of the vane 8, Here, the degree of the interference is determined by the direction of the louver 81 by the discharged air, but the direction can be changed by the external force applied by the user. In other words, the installation direction of the louver 81 can be changed only by the force applied by the user.

According to this aspect, the user can switch the direction of his / her desired direction, particularly, the discharge direction of the air ventilated to the corner portion.

In addition, when the user can adjust the louver 81 as in the present embodiment, the shape of the louver 81 can be made more freely. For example, in the case of the louver 81 placed outside of the vane 8, the height of the up-and-down direction can be made larger so that the discharged air can be more smoothly guided toward the corner portion. Conversely, since the louver 81 placed on the inner side can weaken the switching to the corner portion, the vertical height can be reduced.

Further, the louver 81 can adjust the amount of air to be switched to the corner portion by adjusting the degree of bending in the lateral direction. For example, the outer louver 81 can be bent further toward the corner portion, so that the flow of air toward the corner portion can be more clearly guided.

In addition, as the louver 81 is formed closer to the corner portion, the density of the louver 81 is increased, so that the flow of air toward the corner portion can be made more smooth. On the other hand, in the central portion of the vane 8, the forming density of the louvers is made low so that the flow of the air toward the corner portion can be reduced. This is because the user located at the edge of the ceiling- I have a purpose.

On the other hand, since the louver 81 is a part lying on the upper surface of the vane 8, there is no decrease in the aesthetics that can be caused due to the unnatural shape of the louver 81.

However, the present embodiment has a problem that the angle of the louver must be individually adjusted by the user.

≪ Third Embodiment >

The third embodiment of the present invention is proposed in order to overcome the above-described problems, and a description of the second embodiment will be omitted, and a description thereof will be omitted.

8 is a perspective view showing a vane and its adjacent structure in the air conditioner according to the third embodiment.

Referring to Fig. 8, the vane 81 is fitted in the vane 8 by a pivot hinge 85. Fig. A stopper 95 is provided at a contact position between the louver 81 and the adjustment bar 91 so that the adjustment bar 91 is positioned at a position And moves in the lateral direction to the same extent as the louver 81.

According to the present embodiment, the user can adjust the position of the louver 81 collectively by the operation of pushing or pulling the adjustment bar 91 by one step.

The embodiment described above provides an embodiment in which a louver is provided on the face of the vane. However, in the above-described embodiment, since the louver is placed on the upper surface of the vane 8, the weight of the vane is increased, thereby causing a problem of making the turning operation of the vane difficult.

<Fourth Embodiment>

The fourth embodiment of the present invention overcomes the problems of the first to third embodiments described above and is characterized in that a plurality of structures provided on the vanes are not required. Therefore, the description of any of the above-described embodiments is not intended to be exhaustive.

9 is a front view of a discharge port according to a fourth embodiment of the present invention, and virtually shows the inside thereof.

Referring to FIG. 9, the air conditioner of this embodiment has a discharge port, which can be formed by the drain pan 4 and the front panel 6. On the inner surface of the discharge port 9 formed by the drain pan 4 and the front panel 6, a corner flow path guide 201 is formed as a kind of louver.

In addition, the vane 8 and the vane motor 83 for driving the vane may be provided at the discharge end of the discharge port 9 so that the flow of air in the vertical direction is appropriately switched.

It can be seen that the corner direction flow path guide 201 is bent toward both side ends of the discharge port 9 from the upper side to the lower side. It can be easily predicted that the air passing through the discharge port 9 can be switched to flow toward the corner portion in view of the shape of the corner flow path guide.

7, the degree of formation density, the degree of bending to the left and right, and the width of the discharge side are controlled so that the degree of guiding of the discharge guide action of the air can be controlled There will be.

On the other hand, in the present embodiment, it is explained that both the front panel 6 and the drain pan 4 are provided with the corner direction flow path guide 201. However, the present invention is not limited thereto, and the corner flow path guide 201 may be provided by any one of the structures. However, it can be expected that the ability to switch the air flow direction is further increased by being provided together in the entire region constituting the discharge port. This is because it is more preferable that the length is provided to be long so as to obtain a sufficient flow direction switching effect in a state in which the flow path resistance is not provided. Here, the corner direction flow path guide 201 may be referred to as a louver in the sense that the discharge direction of the air discharged from the discharge port 9 is biased in the left and right direction.

The present embodiment describes that the direction of air flow is switched by the corner direction flow guide provided thinly in the form of air foil. However, such a configuration may cause a reduction in the switching capability to some extent, because the air flowing inside the discharge port 9 has a three-dimensional air flow.

<Fifth Embodiment>

The fifth embodiment of the present invention is different from the fourth embodiment in that the air flowing in the discharge port 9 is three-dimensionally switched in the air flow direction. Therefore, the description of the fourth embodiment is omitted.

10 is a front view of the discharge port according to the fifth embodiment, and virtually shows the inside thereof.

10, the other parts are entirely the same, and the drain pan 4 and the front panel 6 constituting the inner surface of the discharge port 9 are different from each other in that a three-dimensional raised portion 301 is provided. In other words, the drain pan 4 for providing the discharge portion and the portion protruding inward from the inner surface of the front panel 6 are smoothly and three-dimensionally curved so as to face the corner portion so that the flow direction of the discharged air is accurately Guide. Here, the raised portion 301 may be called a louver in the sense that the air discharged through the discharge opening 9 changes its rotational direction in the left-right direction.

In addition, the modifications described in the fourth embodiment may be applied to the case of this embodiment as well.

The embodiments of the present invention described above may be further provided with another embodiment in which the configuration included in any one of the embodiments is applied to another embodiment. For example, the shape, structure, and arrangement of the louver may be included in any one of the first and second embodiments, and such an embodiment is also included in the spirit of the present invention .

According to the present invention, when a ceiling air conditioner is mainly used, air that has been air-conditioned can be blown to a user located in any direction, so that an advantage that the satisfaction of the air conditioner is further improved can be expected. Therefore, there is an advantage that the user's comfort is enhanced and the air conditioning environment desired by the user can be created as desired.

In addition, since the air conditioning environment can be selectively created by the user, the user who is familiar with the conventional type of the ceiling-mounted air conditioning apparatus can operate the air conditioning apparatus according to his or her choice, thereby further enhancing the satisfaction of use.
