Abstract

PURPOSE:To obtain a multitude of variations of the flow of indoor air through employing both of an upper outlet air and lower outlet air and improve especially the comfortable property of air conditioning by a method wherein the rotating center of an airflow deflecting plate for an upper air outlet port is provided at the fore end of the air outlet port to outlet the upper outlet air with an arbitrary angle. CONSTITUTION:The outlet angle of air which flows along an air guider 7 is regulated at the upper air outlet port 3 by an airflow deflecting plate 6. The rotating center of the airflow deflecting plate 6 is provided at a shaft 6a so as to be pivoted to and fixed at any arbitrary angle. According to this method, the outlet air, whose direction is controlled by the airflow direction deflecting plate 6, can be made to flow into any direction of forward, intermediate and upward. Built-in installation may be effected by guiding the outlet air forward by regulating the airflow direction deflecting plate. A temperature difference between the cooling surface side and the normal temperature surface side of the airflow direction deflecting plate 6 may be secured by constituting the same plate 6 of a shell pack structure and interposing a material having a high heat insulating property between a 2-piece member consisting of surfaces A, B. Accordingly, there is no possibility of dewing on the surface of the airflow direction deflecting plate 6 even when normal temperature air is contacted with the surface of the same plate 6.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a blowout structure for an air conditioner, and particularly to a structure suitable for adjusting the angle of blowout air from an upper blowout port of a floor-standing air conditioner.

[Conventional technology]

In the conventional device, as described in Utility Model Application No. 60-82125, holes are opened on the front side and the top side of the upper air outlet, and the blowing angle of the upper air is adjusted by a wind direction plate having a rotation center inside the air outlet. was doing.

Other known examples include those in which the cross-sectional shape of the wind direction plate is T-shaped and the center of rotation is located inside the outlet, as shown in FIGS. 5 and 7, or the direction in which the upper outlet member is attached to the main body. There were also those that selectively fixed the blowing angle.

[Problem to be solved by the invention]

The above-mentioned conventional technology does not take into consideration the angle of air blown from the upper air outlet, and has various problems.

Each problem will be described below with reference to FIGS. 4 to 8.

In FIG. 4, the air outlet 5 is placed in the center, and the upper air outlet 3 is placed above and below it. In an air conditioner provided with a lower outlet 4, the angle of the upper blown air is adjusted by a wind direction plate O. In this device, the upper air outlet 3 is opened in the front and upper sides, and even if the air outlet angle is adjusted with the wind direction plate 6, the adjustment may not be complete. %, when the air conditioner is installed built-in within a wall, there is discharged air that escapes upward even if the wind direction plate 6 is adjusted horizontally.
A problem occurs with built-in installation.

In FIG. 5, the upper air outlet 3 is adjusted upward and forward by rotating the wind direction plate 6. As shown in FIG. 6 in detail, the wind direction plate 6 has a single-shape shape, and the center of rotation 6α is located inside the air outlet.

In this device, the blowing angle of the upper blowing air becomes upward when the wind direction plate 6 is adjusted as shown by the solid line in FIG. 6, and forward when adjusted as shown by the broken line in FIG. In this case, the top blown air flows upward and forward, but does not flow diagonally in the middle. Air conditioners are most often used with an oblique blowout angle, but this device did not take this diagonal blowout into consideration.

In FIG. 7, the air outlet angle of the upper air outlet 3 is adjusted by attaching the air outlet member 6b to the upper side and the front side. For details, as shown in FIG. 8, the air outlet member 6b has one side open and the other side in the middle, and when the air outlet member 6b is in the position shown by the solid line in FIG. 8, the air blowing angle is upward as shown by the broken line. When the position fVC is lowered, it becomes forward-looking. At this time, the outlet member 6b is fixed to the air conditioner main body 1 by a screw 6c. Like the above-mentioned devices, this device did not take into account oblique blowing, nor did it take convenience into account in that adjustment of the blowing angle involved removing and attaching screws.

[Means to solve the problem]

The above object is achieved by providing the center of rotation of the wind direction plate of the upper outlet at the tip of the outlet.

[Effect]

The wind direction plate 6 of the upper air outlet 3 has its center of rotation at the position 6α, rotates between the position shown by the solid line and the position shown by the broken line in FIG. 1, and is fixed at an arbitrary angle. The blowing air controlled by the wind direction plate 6 is directed forward.

In the middle, it flows diagonally and upwards, making it 5.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1, 2, and 3.

In FIG. 2, the air conditioner of the present invention has a structure in which a makeup grille 2 is attached to the front of a main body 1, and an upper air outlet 3. It has a lower air outlet 4° at the bottom and an air outlet 5 in the middle, and the air blowing angle of the upper air is adjusted by a wind direction plate 6.

The flow of air will be explained with reference to FIG. After passing through the heat exchanger 10, the air blown through the air inlet 5 is rectified by the air cider 7, and then sent to the upper cross flow fan 81, the lower cross flow fan 9Kll, and the upper air outlet 3, respectively.
and is blown out from the lower outlet 4. The upper air outlet 3 is equipped with a wind direction plate 6, so that the blowing angle of the air blown from the upper part can be adjusted.

A mechanism for adjusting the blowing angle of air blown from the top will be explained with reference to FIG. The blowing angle of the air flowing along the air guider 7 is adjusted by the wind direction plate 6 at the upper blowing outlet 3. The wind direction plate 6 has its center of rotation at the axis 6α, and the first
It rotates between the position shown by the solid line and the position shown by the broken line, and is fixed at any angle. Thereby, the blown air controlled by the wind direction plate 6 can flow in any direction, such as forward, diagonally in the middle, or upward.

In this structure, the wind direction plate 6 located at the upper air outlet in FIG. 2 may be adjusted to the position indicated by the solid line and broken line in FIG. 1, as explained above.
E Both sides should be visible to the user.

In particular, in the floor-standing air conditioner disclosed in this example,
Both sides A and B appear on the outer surface of the product body. Therefore, it is possible to make the wind direction plate 6 a two-piece shell pack structure consisting of the A side and the B side, and make both sides have the same finished surface.

Further, in FIG. 1, the position of the wind direction plate 6 at the upper air outlet 3 can be adjusted to any angle, but depending on the angle, the air flow rate on the A side and the B side may change.

The way the air flows changes in various ways, and during cooling operation, cold air and normal temperature air mix on the surface of the wind direction plate 60, and moisture in the air may condense on the surface of the cooled wind direction plate 6.

Therefore, the wind direction plate 6 has the above-mentioned shell pack structure, and 3
．． By interposing a highly heat insulating material in the two-piece member consisting of eight surfaces, a temperature difference between the cooling surface side and the normal temperature side of the wind direction plate 6 can be ensured. Therefore, even if normal temperature air comes into contact with the surface of the wind direction plate B, there is no possibility of condensation on the surface of the wind direction plate 6.

Finally, to describe the unique effects of this embodiment, in a floor-standing air conditioner, the blowing angle of the upper blowing air is changed to forward,
It can be oriented upward or diagonally at any angle, and even when installed as a built-in device stored inside a wall, the blowout air can be directed forward by adjusting the wind direction plate. Furthermore, dew condensation on the wind direction plate, which has been difficult in air conditioners, can be solved by making the wind direction plate have a heat insulating structure.

〔Effect of the invention〕

According to the present invention, the upper blown air can be blown out at any angle, and when used in combination with the lower blown air, there are many variations of indoor air flow. It has the effect of improving comfort, especially for various needs. In addition, by forming both sides of the wind direction plate into a shell pack structure, there are no gaps, gate marks, etc. during injection molding that are sometimes found in conventional integrated wind direction plates. Furthermore, since there is no condensation on the surface of the wind direction plate, there is an effect of improving performance and comfort.
