[The problem that the idea aims to solve]

According to the above-mentioned conventional configuration, there was a problem in that the wind direction and wind speed could not be adjusted sufficiently. This is due to the fact that there are few adjustment mechanisms and most of them are fixed.

The present invention was developed based on these points, and its purpose is to provide air-conditioning air that can uniformly send wind into the area to be air-conditioned by sufficiently adjusting the wind direction and wind speed. An object of the present invention is to provide a blowing device.

[Means to solve the problem]

In order to achieve the above object, the air conditioning air blowing device according to the present invention is attached to an air conditioning air outlet, adjusts the flow rate of air conditioning air flowing out from the air conditioning air outlet, and has an air flow rate with a diffusion function. a regulating valve mechanism; and an air outflow mechanism that is installed to block the outflow side of the air conditioning air outflow port and has a function of blowing out and diffusing the air conditioning air supplied from the air conditioning air outflow port into the air conditioning target area. and a rectifying mechanism provided between the air flow rate regulating valve mechanism and the air outflow mechanism and having a diffusion function, and a direction regulating valve mechanism provided between the rectifying mechanism and the air outflow mechanism. It is characterized by this.

[Effect]

First, the air conditioning air outlet has an air flow rate adjustment valve mechanism that adjusts the flow rate, and this air flow rate adjustment valve mechanism adjusts the flow rate, and this air flow rate adjustment valve mechanism also has a diffusion function. , where the air is first diffused. Next, the air is rectified by a rectifying mechanism and is also diffused here. It is then further diffused by the directional valve mechanism and finally diffused by the air outflow mechanism and flows out into the area to be air conditioned.

The air conditioning air outlet is, for example, an outlet of an air conditioning duct, or an outlet formed in a ceiling, a wall, or the like.

Although various types of air flow rate adjustment valve mechanism and direction adjustment valve mechanism can be considered, a typical example is one in which the flow rate or direction is adjusted by reciprocating or rotating a valve body.

The air outflow mechanism and the rectification mechanism include, for example, a perforated plate, a mesh, and the like, and there are various mounting angles, shapes, and the like.

Further, the directions of diffusion by each of the above mechanisms are not particularly limited, but the directions may be different, or may be different alternately, or may be diffused in all directions.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. Reference numeral 101 in FIG. 1 indicates a room that is an air-conditioned area, and the ceiling 10 of this room 101
2 is attached with an air blowing device 103 for air conditioning. That is, the frame 104 of the device 103 is fixed to the air conditioning air outlet 102a of the ceiling 102. A regulating valve 105 is located above the center of the frame 104 and is connected to the lease spring 1.
06, and this regulating valve 1
An adjustment bolt 107 is attached to 05. By turning the adjustment bolt 107 in a predetermined direction, the adjustment valve 105 is raised and lowered, thereby adjusting the air flow from above to some extent.

A diffusion plate 108 is attached to the lower end of the frame 104. This diffuser plate 108 has a V-shape as shown in FIG.
08 itself also functions as a conventional differential user panel. This diffusion plate 108 is, for example, a so-called punched metal made of austenitic stainless steel. As shown by the two-dot chain line in FIG. 2, a hinge 112 is provided at one end of the frame 104, and the frame 104 can be opened and closed together with the diffusion plate 108 using the hinge 112 as a fulcrum. Reference numeral 113 in the figure is a fixing screw. Note that not only the diffusion plate 108 but all the members in this embodiment are made of austenitic stainless steel. A rectifying plate 110 is attached inside the diffusion plate 108. The current plate 110 has an inverted V-shape as shown in FIG. 2, and is made of punched metal made of austenitic stainless steel like the diffuser plate 108 described above.

A wind direction adjustment valve 111 is installed between the diffusion plate 108 and the rectifying plate 110, and the device 10
This is to effectively diffuse the air in the direction of the short side of No. 3.

The operation will be explained based on the above configuration. Device 1
The air supplied from above 03 is first supplied to the regulating valve 10.
5, the air volume is adjusted to some extent. At the same time, the lease spring 106 causes the device 103 to
is diffused in the long side direction. In addition, adjustment bolt 1
By operating 07, the adjustment valve 105 can be raised and lowered to adjust the air volume. The air that has flowed into the device 103 via the regulating valve 105 is diffused by the diffusion plate 108, and
10 and the wind direction adjustment valve 111, the air is restricted from blowing directly downward and is effectively rectified and diffused in the direction of the short side of the device 103.

Due to the above-described actions, air is sufficiently diffused and supplied to the entire area within the chamber 101, and the air is supplied to the entire area within the chamber 101.
This will ensure uniform air conditioning inside.

According to this embodiment, the following effects can be achieved. That is, by effectively adjusting the wind direction and air volume, the air conditioning air can be uniformly blown into the room 101, and air conditioning with good airflow distribution at low wind speeds can be performed. This is because the lease spring 106 is first used as an elastic member for adjustment of the regulating valve 105, and this lease spring 106 enables the device 103 to spread in the long side direction. Next, the diffuser plate 108 is used as a differential user panel, has a V-shape, and is made of punched metal. Next, an inverted V-shaped rectifying plate 110 made of punched metal is provided, and a wind direction adjustment valve 111 is provided to effectively diffuse the air, particularly in the direction of the short side of the device 103.

Note that the present invention is not limited to the above embodiment. First, there are various configurations of each valve mechanism, and a mesh-shaped mechanism may also be used as the air outflow mechanism and rectification mechanism in addition to the above-described embodiments.

[Effects of the invention] According to the air-conditioned air blowing device according to the present invention,
Since there are many mechanisms for adjusting the air flow rate and direction, and some of them can be adjusted as appropriate, it is possible to perform good air conditioning by adjusting the air flow rate and direction.
