Abstract

PURPOSE:To gradually increase the angle of a rectifying plate when the rectifying plate is opened by making the distance between an interlocking shaft and a rotating shaft of a lower rectifying plate larger than the distance between an interlocking shaft and a rotating shaft of an upper rectifying plate, and making the distance between upper and lower interlocking shafts of the connecting rod smaller than the distance between adjacent upper and lower interlocking shafts of the connecting rod. CONSTITUTION:A plurality of rectifying plates 1, 2 and 3 are disposed vertically and equidistantly at a discharge port 8 provided in the front of a cylindrical vane 102, and are rotatable around rotary shafts 4 at both ends thereof. The interlocking shafts 7 and 9 provided rearward of the side surfaces of the rectifying plates 1 and the rectifying shafts 7 and 9 provided rearward of the side surfaces of the rectifying plate 2 and the rectifying plate 3 are rotatably connected by a connecting rod 5. The length L of the connecting rod 5 is made smaller than the distance D between the rotary shafts 4. The distance A between the centers of the rotary shaft 4 and the interlocking shaft 9 is slightly longer than the distance B between the centers of the rotary shaft 4 and the interlocking shaft 7. In the above described structure, when the rectifying plates 1, 2, and 3 are in the opened state, the angles of the rectifying plates are increased more as they are disposed at upper positions. Therefore, when an air flow flows out at an angle of alpha deg., the distribution of the air flow rate uniformly extends depending on respective rectifying plates, and the air flow can be discharged in a wide range from the breast to the face of the person.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a device for controlling the direction of air blown from an electric fan or air conditioner.

BACKGROUND OF THE INVENTION In recent years, with the spread of air-conditioning equipment, there has been a trend towards creating more comfortable wind through improved methods of controlling blown air.

Conventionally, this type of wind direction control device has had a structure as shown in FIGS. 6 and 7. That is, blades 102 are attached to the electric motor 101, and a rectifying plate 104 is provided at the outlet of the blower casing 103, which are interlocked by an interlocking plate 105.

Each of the above-mentioned parts was housed in the main body 106.

Here, the higher the current plate 104 is placed, the larger the angle of elevation, and the lower the plate 104 is placed, the larger the angle of depression, thereby expanding the range of wind direction in the vertical direction and creating a comfortable wind that envelops the upper body. This is something that can be obtained.

Problems to be Solved by the Invention In such a conventional configuration, as shown in FIG. As the angle increases, a gap T is created between the rectifier plates, which causes a problem in that dust tends to enter the inside of the air outlet when the air outlet is not used for a long period of time.

The present invention is intended to solve these conventional problems.
It is an object of the present invention to provide a wind direction control device that can create a wide range of wind speed distribution, which is a conventional function, and can also completely close the current plate.

Means for Solving the Problems In order to achieve this object, the present invention has a cylindrical blade built into a main body, a volute chamber covering this blade, and a volute chamber disposed at equal intervals in the vertical direction at the outlet of the volute chamber. a plurality of rectifying plates, a rotating shaft rotatably supporting the rectifying plates at both ends, at least one interlocking shaft provided rearward from the rotating shaft, and each of the vertically adjacent rectifying plates; It has a connecting rod that rotatably connects the interlocking shaft, and when looking at the relationship between a pair of adjacent current plates of the current plate, the distance between the interlocking shaft of the lower current plate and its rotation axis is the same as that of the upper current plate. The distance between the interlocking shaft and its rotation axis is greater than that of the connecting rod, and the distance between the upper and lower interlocking axes of the connecting rod is smaller than the distance between adjacent rotation axes.

Function: With this configuration, when the equipment is operating, a wide range of wind speed distribution can be obtained by the function of the rectifying plates arranged so that the angle gradually widens, and when the equipment is not operating, the rectifying plates are arranged to gradually widen the angle. The board can be completely closed.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1, 2, 3, and 4. Incidentally, since the blower device is the same as the conventional example, the same number will be given and detailed explanation will be omitted.

As shown in the figure, a plurality of current plates 1.2.3 are arranged at equal intervals in the vertical direction at the air outlet 8 provided in front of the cylindrical blade 102. The current plates 1, 2.3 are mounted rotatably around rotation shafts 4 at both ends. An interlocking shaft 7 provided on the rear side of the rectifying plate 1 and an interlocking shaft 9 provided on the rear side of the rectifying plate 2 are rotatably connected by a connecting rod 6.
An interlocking shaft 7 provided on the rear side of the rectifying plate 3 and an interlocking shaft 9 provided on the rear side of the rectifying plate 3 are rotatably connected by a connecting rod 5. Here, the length L of the connecting rod 5 is smaller than the distance between the rotating shafts 4. Further, the distance A between the centers of the rotating shaft 4 and the interlocking shaft 9 is slightly longer than the distance B between the centers of the rotating shaft 4 and the interlocking shaft 7.

In the above configuration, when the current plate 1.2.3 is in the open state,
The angle increases as the angle of each rectifying plate is placed higher, so if the wind flows out at an angle of α0, the wind speed distribution will be uniformly spread by each of the rectifying plates, and the angle will increase as the angle increases. It can blow out over a wide area from the face to the face.

Further, when the current plate 2 is pushed down by γ0 from the open state to a near vertical state, the current plate 1 is also pushed down by the connecting rod 6. Here, the distance A between the centers of the rotating shaft 4 of the current plate 20 and the interlocking shaft 9 is longer than the distance B between the centers of the rotating shaft 4 of the current plate 1 and the interlocking shaft 9, and the length L of the connecting rod 5 is: Rotation axis 4
Since the distance between them is smaller than the distance between them, the rotation angle of the current plate 1 is β0, which is larger than γ0, and the current plates 1 and 2 can be closed without any gap. Similarly, the current plates 2 and 3 can be closed without any gaps, and the air outlet 8 can be completely closed as shown in FIG.

Effects of the Invention As explained in the above embodiments, according to the present invention, when the current plate is opened, the angle of the current plate gradually increases to obtain a wide range of wind speed distribution. By lowering the rectifying plates, each baffle plate can be brought into a fully closed state without any gaps, thereby realizing an excellent wind direction control device that can prevent dust from entering from the air outlet.
