Abstract

PURPOSE:To obtain an airflow direction changing device, simple, inexpensive arid highly reliable without employing any complicated link mechanism, by a method wherein an airflow direction changing body is rotated to change the direction of outlet air automatically. CONSTITUTION:An airflow direction changing body 7 is fitted into an air outlet port 5. The airflow direction changing body 7 is a cylindrical rod body, formed of a resin material having heat insulating property, and is provided with a shaft for turning while a plurality of penetrated passages 8, forming air outlet passages, are provided in directions intersecting with the axis for turning. The penetrated passages 8 are arranged so that the directions of central axes of the holes are deviated from each other. The directions of the airflow passages 8 are turned and the directions of airflows are fluctuated by turning the airflow direction changing body 7. A plurality of penetrated passages 8 are arranged on the airflow direction changing body 7 whereby outlet air or outlet airflow, guided by an air-conditioning machine, is sent out as comfortable and uneven air flow.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a wind direction changing device for controlling a blowing direction of blown air in a decorative panel of an air conditioner indoor unit.

[0002]

2. Description of the Related Art A conventional air-condition changing device for air conditioning is disclosed in Japanese Patent Laid-Open No.
As described in Japanese Laid-Open Patent Publication No. 41845/1992, a method in which the angle of the wind direction plate combined by flat plates is operated by a rotary motion of an electric motor via a link mechanism using a rod is general.

[0003]

In the above-mentioned prior art, since the wind direction plate is operated through the linear motion of the link mechanism using the rotary motion of the motor by using the parts such as the rod, the number of parts is increased and the structure is complicated. Yes, especially when the number of air conditioner indoor units and the number of decorative panel outlets increases in two or four directions, the number of parts increases, the mechanism becomes more complicated, the cost increases, and the moving parts differ. There is a risk that the reliability may be reduced due to noise and malfunction. Furthermore, since each part is located in the blowout air passage, it is necessary to prevent the flocking or the like from being exposed to each part.

An object of the present invention is to provide a simple, inexpensive and highly reliable wind direction changing device without using a complicated link mechanism. Another object of the present invention is to provide a less expensive wind direction changing device that eliminates the need for flocking.

[0005]

In order to achieve the above object, the present invention uses a cylindrical rod body having an axis in the longitudinal direction. In this cylindrical rod body, a plurality of through holes were used as blowout air passages in a direction intersecting the axis.

By rotating the wind direction body, the wind direction of the blown air can be automatically changed. Since this wind direction body only rotates about its axis, it can transmit the rotation movement of the electric motor, which is the rotation drive source, by means of gears, and it is not necessary to use a complicated link mechanism.

Further, by using a heat insulating resin material such as styrofoam as the material of the wind direction member, it is not necessary to take into consideration the dew condensation even without processing such as hair transplanting.

[0008]

[Operation] The wind direction body rotates about the axis. This wind direction body has a plurality of through holes in the direction intersecting the axis, in the longitudinal direction of the cylindrical rod body,
Since each angle is shifted to make an air outlet passage,
The blowing direction of the blowing air can be moved in the direction of rotation of the wind direction body. By stopping the rotation of the wind direction body, an arbitrary blowing direction can be obtained. Further, since the angles of the through holes are different from each other, it is possible to sequentially blow in the longitudinal direction of the wind direction body, and a comfortable wind can be obtained in a wide range.

Since the wind direction body is driven by a small electric motor,
Since the driving force can be transmitted directly to the shaft of the wind direction member or by a gear, a link structure is not used, a simple structure is advantageous in terms of cost, and a highly reliable wind direction changing device can be realized. .

Further, by using a resin material having a heat insulating property such as styrofoam as the material of the wind direction member, there is no problem such as dew condensation even if the processing such as the flocking and the attachment of the heat insulating material is not caused, and it is inexpensive. A wind direction changing device can be created.

[0011]

[Embodiment] FIG. 1 shows that air blowing in a room is bidirectional.
It is a ceiling-mounted decorative panel, and in FIG. 2, there are four air outlets.
Oriented ceiling-mounted decorative panel. One embodiment of the present invention is shown in FIG.

A wind direction body 7 is fitted in the air outlet 5. The wind direction body 7 is a cylindrical rod body formed of a resin material having a heat insulating property, has a shaft 6 for rotating, and has a plurality of through holes 8 forming a blowout air flow path in a direction intersecting with the shaft. I have one. Further, the through holes are arranged so as to be displaced in the hole central axis direction.

The wind direction body 7 is disposed at the air outlet 5, and the wind direction body 7 is rotated by a small motor or the like (not shown), so that as shown in FIGS. 4, 5 and 6. In the wind passage 8
The direction of will rotate and the wind direction will fluctuate. Since a plurality of through passages 8 are arranged in the wind direction body 7 so as to be displaced from each other, the blown air and wind into the air-conditioned room are blown out as a comfortable uneven wind.

As shown in FIGS. 7, 8 and 9, by forming the through holes 9 and 10 into large and small openings, not only the direction of the wind, but also the strength of the wind changes. It is also possible to add a new element of comfort.

[0015]

According to the present invention, when air is blown out from an air conditioner indoor unit, a simple structure can be used as an automatic changing device for the blowing direction. Is advantageous to. The contents of wind fluctuations include vertical fluctuations, deviations in the blowing direction on the left and right, and strength fluctuations.
These can be automatically changed and can be an element of comfort.

Further, the conventional structural measures against the phenomenon of dew condensation, such as the attachment of a heat insulating material and the flocking process, are not necessary at all because the wind direction body itself is a resin molded body having a heat insulating property, and the cost is reduced. Will have an advantage.
