<First Embodiment>

1 is an exploded perspective view of an air conditioning apparatus according to an embodiment of the present invention. However, in FIG. 1, it should be referred to that the inverted state of the installation of the air conditioning apparatus is displayed for convenience of understanding.

Referring to FIG. 1, the air conditioner of the present embodiment is a ceiling type air conditioner, which includes a case 1, a fan 2 accommodated in the case 1, and an open portion above the case 1. An orifice provided in the drain pan 3 to be placed, the suction guide 4 provided in the inner portion of the drain pan 3, and the inner opened portion of the suction guide 4 to smoothly introduce air ( 5), a front panel 6 forming a front surface of the air conditioner and dividing the inside and the outside, and an intake grill 7 covering the inner space of the front panel 6 to filter the air flowing in from the outside. do.

The suction grill 7 forms a suction end to which the outside air is sucked. Therefore, all the air flowing into the air conditioner passes through the suction grill 7.

The front panel 6 is a part forming the front appearance of the air conditioning apparatus observed by the user, and constitutes a device for stably installing the suction grill 7, and further, guides the flow of the discharged air. Discharge openings 9 are provided at four corners of the front panel 6, and the discharge openings 9 are provided with vanes 8, and the angle of the vanes 8 is controlled to discharge through the discharge openings. The up and down position where the air is reached will be different.

The suction guide 4 and the orifice 5 is an article for stably introducing external air toward the fan 2 in a low noise state, but both may be provided as separate articles as shown. Both may be provided in an integrated article.

The drain pan 3 serves to receive and store condensate generated in the heat exchanger and to discharge the condensate from the heat exchanger, and at four corners of the drain pan 3, a discharge port through which air discharged from the fan 2 passes is provided. It is prepared.

It will be understood that the fan 2 is connected to a motor to rotate the fan. In addition, it is natural that heat exchangers are disposed on four sides of the case 1 so that heat exchange is performed on the air and the refrigerant pipe.

The operation of the air conditioner will be briefly described.

When the fan 2 is rotated, a negative pressure atmosphere is created in the inner space of the case 1. Then, the outside air is sucked through the suction grill 7, the orifice 5, the suction guide 4, and the fan 2 by the negative pressure inside the case 1. Then, the heat exchanged air passing through the heat exchanger is discharged to the outside through the discharge port of the drain pan (3), the front panel (6).

2 is a plan view of the air conditioning apparatus according to the present embodiment, in which a front panel of the air conditioning apparatus is shown.

Referring to FIG. 2, discharge holes 9 are formed at four corners of the front panel 6. And the vane 8 which adjusts to the flow direction of the air discharged through the discharge port 9 is provided in the opening part of the discharge port 9. The setting angle of the vanes is automatically adjusted by a motor installed on one side of the vanes 8.

Here, the front panel 6 is provided in a quadrangular shape, and the discharge holes 9, the vanes 8, and the vane motors (see 83 in FIG. 4) are individually installed at each corner of the square of the front panel 6. It is. Therefore, the flow direction of the air discharged through each discharge port 9 can be adjusted individually.

In the present embodiment, the direction of the air discharged through the discharge port 9 can be adjusted not only in the vertical direction by the vane 8, but also in the horizontal direction. The related structure and method are demonstrated in detail.

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 air conditioned air is discharged. A vane 8 is provided inside the discharge port 9, and a louver 81 is provided on an upper surface of the vane 8. The vane 8 may be discharged by adjusting the discharge air in the vertical direction, the discharge air may be adjusted by the louver 81 in the horizontal direction. In addition, it will be easily understood that the louvers 81 and the vanes 8 can be automatically adjusted by their respective motors.

Here, in the technical field for adjusting the air direction of the air conditioning apparatus, it is generally referred to as the vane to adjust the discharge direction of air in the up and down direction, and generally referred to as louver to control the discharge direction of the air in the left and right directions. Reference is made in the description of.

Referring to FIG. 4, a structure and a method capable of operating the vanes and louvers may be more clearly understood. First, the vanes 8 for switching the air flow direction in the vertical direction are provided with ribs 90 at both ends thereof. In addition, the driving shaft of the vane motor 83 is connected to any one side of the rib 90, the vane 8 can be adjusted in the vertical direction at an appropriate angle.

At least one, preferably a plurality of louvers 81 are supported on the top surface of the vanes 83. The louver 81 is rotatably supported on the upper surface of the vane 8 by the pivot hinge 85. In addition, a slot 84 is formed at one side of the louver 81, and the operation bar 89 is fitted into the slot 84. The louver 81 may move left and right about the pivot hinge 85 by the operation unit 89. In order to enable the louver 81 to move left and right by the operation bar 89, stoppers 95 are provided at positions of the operation bar 89 in contact with the louver 81, respectively.

The louver 81 may have a larger discharge side than the inlet side so that air discharged to the outside through the louver 81 may be smoothly discharged along the outer surface of the louver 81.

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

On the other hand, when the vane 8 is rotated up and down, in order to prevent the operation bar 89 and the louver 81 from causing interference, when the operation bar 89 is centered on the rib 90, It can be seen that the vane motor 83 is provided on the same shaft in the horizontal direction. Then, the vane 8 rotates up and down and the operation bar 89 moves left and right independently of each other.

5 is a view showing a state in which the air conditioning apparatus according to the present embodiment is installed.

Referring to FIG. 5, when the ceiling type air conditioner 10 is installed on the ceiling, since the ceiling type air conditioner is provided in a quadrangle, air may not be properly blown to the corners of the air conditioner. In other words, since the air discharged through the four sides of the ceiling type air conditioner is blown only in the discharge direction, the user located at the corner can hardly feel the air flow. Each corner portion is indicated by reference numerals 11, 12, 13, 14.

Therefore, when the user is located in the corner portion, it is necessary to allow the air conditioned to be blown to the corresponding position. Then, the user may control the air conditioning apparatus to allow air to be blown in the corresponding direction.

In more detail, the screen as shown in FIG. 5 may be displayed on the operation unit of the air conditioning apparatus, and air may be discharged to a corresponding portion. Then, the corner air conditioning mode is performed in which air conditioned in the indicated direction is blown.

FIG. 6 is a flowchart illustrating a control method of an air conditioner in which a corner air conditioning mode is performed. Referring to FIG. 6, the corner air conditioning mode will be described in more detail.

First, the user selects a position of a specific corner portion where air-conditioned air is to be blown with reference to the screen or other indicating means shown in FIG. 5 displayed on the display window of the device illustrated by the remote controller (S1). Then, the louver 81 is controlled in order to allow the air conditioned to the selected position to blow (S2).

In more detail, a process in which the louver 81 is controlled will be described with reference to FIG. 5.

For example, if it is indicated that the air conditioned to the corner portion indicated by 11 is blown, the louver 81 placed between 11 and 14 is deflected to the right to allow air to be blown to the right. And, the louver 81 placed between the 12 and 11 is to be deflected downward so that air is blown downward.

According to the position where the louver is placed, the air conditioned to the corner portion 11 can be blown.

On the other hand, even when the louvers 81 are rotated in the left and right directions, the vertical rotation of the vanes 8 does not cause interference with the louvers. Therefore, the flow direction of the air discharged in the vertical direction may also be operated exactly as desired by the user. The reason for such an operation has already been described.

Since the corner air conditioning mode as described can be performed, it can be expected that the old problem that has been pointed out as a fundamental problem of the ceiling type air conditioning apparatus can be solved.

The above-described first embodiment discloses the idea that the user can use the air conditioner more conveniently by switching the discharge direction of the air conditioner according to the situation desired by the user. However, the installation of a separate movable louver may be optimally used in the case of expensive air conditioners, but even in the case of low-cost models, such corner air conditioning mode is preferable because it causes a considerable increase in material cost. Can not.

Second Embodiment

The second embodiment of the present invention is to overcome the problems of the first embodiment described above, and is characterized by providing a manually operated louver instead of an automatically operated louver. Therefore, the description of the first embodiment is used for the parts without specific description, and the description is omitted.

7 is a perspective view showing a vane and its adjacent configuration in the air conditioning apparatus according to the second embodiment.

Referring to FIG. 7, the vanes 8, the ribs 90, and the vane motor 83 are provided as in the first embodiment. And the louver 81 is provided also in the upper surface of the vane 8, The said louver 81 is clamped on the upper surface of the vane 8 by the pivot hinge 85. As shown in FIG. Here, the degree of interference fit is such that the direction of the louver 81 is not changed by the discharged air, but the direction can be changed by an 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 form, the user can switch the direction desired by the user, in particular, the discharge direction of the air air-conditioned 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 will be more free. For example, in the case of the louver 81 placed on the outside of the vane 8, the upper and lower heights may be made larger so that the discharged air is guided more smoothly toward the corner portion. On the contrary, since the louver 81 placed inside may weaken the switching to the corner portion, it is possible to reduce the vertical height.

Furthermore, the louver 81 may adjust the amount of air switched toward the corner part by adjusting the degree of bending in the left and right directions. For example, the outer louver 81 can be bent further towards the corner, thereby allowing the flow of air toward the corner to be guided more clearly.

In addition, the closer to the corner portion, the more the density of the louver 81 is formed, so that the flow of air toward the corner portion can be made smoother. On the contrary, by forming a low density of louvers at the center of the vane 8, the flow of air toward the corners can be reduced, which is intended to extend the air to the user located at the side of the ceiling air conditioner. Has a purpose.

On the other hand, since the louver 81 is a component lying on the upper surface of the vane 8, there is no reduction in aesthetics that may occur due to the unnatural shape of the louver 81.

However, this embodiment has a problem that the user must individually adjust the angle of the louver.

Third Embodiment

The third embodiment of the present invention is proposed in order to overcome the above-mentioned problems, and the part without the detailed description uses the description of the second embodiment, and the description thereof is omitted.

8 is a perspective view showing a vane and its adjacent configuration in the air conditioning apparatus according to the third embodiment.

Referring to FIG. 8, vanes 81 are fitted to vanes 8 by pivot hinges 85. And an adjustment bar 91 is fitted to one side of the louver 81, and a stopper 95 is provided at the contact position of the louver 81 and the adjustment bar 91, so that the adjustment bar 91 is The louver 81 is moved in the lateral direction by the same degree.

The adjustment bar is a component operated by a user, and according to the present embodiment, the user can adjust the position of the louver 81 collectively by pushing or pulling the adjustment bar 91 once.

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, the louver is placed on the upper surface of the vane 8, so that the weight of the vane increases, thereby causing a problem that makes the vane rotational operation difficult.

Fourth Embodiment

The fourth embodiment of the present invention overcomes the problems of the first to third embodiments and is characterized by eliminating the need for a plurality of structures installed on the vanes. Therefore, the part which does not have a detailed description uses the description of any above-mentioned embodiment.

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

9, the air conditioner of the present embodiment has a discharge port, which may be made 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 vanes are installed at the discharge end of the discharge port 9 so that the flow of air in the vertical direction can be switched appropriately.

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

Like the louver provided in FIG. 7, the corner direction flow guide 201 may also adjust the formation density, the degree of bending to the left and right, the width of the discharge side, and the like to guide the operation of the discharge guide of air. There will be.

On the other hand, in this embodiment, it is described that the corner flow path guide 201 is provided to both the front panel 6 and the drain pan 4. However, the present invention is not limited thereto, and the corner flow path guide 201 may be provided by any one structure. However, by being provided together in the entire area constituting the discharge port, it can be expected to further increase the flow direction switching capacity of the air. This is because, in order to obtain a sufficient flow direction switching effect in a state in which it is provided in a fixed type and there is no flow path resistance, it is more preferable that the length is provided longer. Here, the corner 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 bent in the left and right directions.

This embodiment has been described that the flow direction of air is switched by the corner direction flow guide provided in the form of air foil (air foil) thin. However, such a configuration may cause a decrease in the switching capability to a certain degree, since the air flowing inside the discharge port 9 has a three-dimensional flow of air.

Fifth Embodiment

The fifth embodiment of the present invention improves the problem posed by the fourth embodiment, and is characterized in that the structure in which the flow direction of air is switched three-dimensionally to the air flowing inside the discharge port 9 is different. Therefore, the part without description makes reference to the description of the fourth embodiment.

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

Referring to FIG. 10, the other parts are generally the same, and the three-dimensional ridges 301 are provided on the drain pan 4 and the front panel 6 forming the inner surface of the discharge port 9. In other words, the inner side of the drain pan 4 and the front panel 6 providing the discharge portion are curved inwardly three-dimensionally so as to face the corner portion so that the flow direction of the discharged air is accurately To be guided. Here, the ridge 301 may be referred to as a louver in the sense that the rotational direction of the air discharged through the discharge port 9 is changed in the left and right directions.

In addition, the modifications described in the fourth embodiment may be similarly applied to the case of the present embodiment.

In the above-described embodiment of the present invention, another embodiment may be further provided by applying the configuration included in one embodiment to another embodiment. For example, the shape, structure, and arrangement of the louver may be included in the first embodiment, which is included in any one of the second embodiments, and it is apparent that such an embodiment is included in the spirit of the present invention. .

According to the present invention, when the center of the air conditioner, the air-conditioned air can be blown to the user located in any orientation, it can be expected to further improve the satisfaction with the air conditioner. Therefore, the user's comfort is enhanced, the air conditioning environment desired by the user has the advantage that 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 ceiling type air conditioning apparatus can operate the air conditioning apparatus according to his or her own choice, thereby improving the satisfaction of use.
