Description

「中央部」は、「中心部」だけでなく、その周辺を含む概念である。具体的には、送風機の吹き出し口と、試験室の天井、底及び側壁の間に隙間がある状態を指す。本態様によると、送風機の上下や左右に空間があるので、送風機から吹き出される空気を拡散させ易い。 The "central part" is a concept that includes not only the "central part" but also its surroundings. Specifically, it refers to a state in which there is a gap between the outlet of the blower and the ceiling, bottom, and side walls of the test room. According to this aspect, since there are spaces above, below, and to the left and right of the blower, it is easy to diffuse the air blown out from the blower.

これに対して、図５（ｂ）の様に、風向変更部材３３が前方に移動し、羽根部材３１の一部が風向変更部材３３の筒部４８から露出する位置に、風向変更部材３３があるならば、羽根部材３１で起こされた送風は、筒部４８が無い部分から周方向に向かって吹き出される。
羽根部材３１の全部が風向変更部材３３の筒部４８から露出する位置に、風向変更部材３３があるならば、羽根部材３１で起こされた送風は、全て、拡散方向に向かって吹き出される。 On the other hand, as shown in FIG. 5B, the wind direction changing member 33 moves forward, and the wind direction changing member 33 moves to a position where a part of the blade member 31 is exposed from the cylinder portion 48 of the wind direction changing member 33. If there is, the air blown by the blade member 31 is blown out in the circumferential direction from the portion without the cylindrical portion 48 .
If the air direction changing member 33 is located at a position where the entire blade member 31 is exposed from the cylindrical portion 48 of the air direction changing member 33, all of the air blown by the blade member 31 is blown out in the diffusion direction. .

Claims

An environmental test apparatus having a test room in which a test piece is installed, air conditioning means, and a blower, wherein air adjusted by the air conditioning means is blown into the test room by the blower,
The blower has a blade member, a wind direction changing member, and a rotating shaft,
The blade member is a centrifugal rotary blade that imparts centrifugal force to the sucked air by rotating and blows out the air in a direction that intersects the axial direction of the rotating shaft,
The wind direction changing member has a cylindrical portion with both ends open,
one end of the cylindrical portion serves as a suction side opening located on the suction side of the blade member;
The other end of the cylindrical portion serves as a blowout side opening,
The cylindrical portion can cover at least a portion of the circumference of the blade member,
A flow direction of part or all of the air blown out from the blade member in the intersecting direction is changed by the cylindrical portion, and the air whose flow direction has been changed is blown from the blowing side opening. An environmental test device characterized by being discharged.

2. The environmental test apparatus according to claim 1, wherein the wind direction changing member is movable in the axial direction.

The position and/or shape of the wind direction changing member can be changed, and a state in which part or all of the blade member is exposed from the cylindrical portion, and/or a state in which part or all of the blade member is exposed from the cylindrical portion. 3. The environmental test apparatus according to claim 1, wherein the environmental test apparatus can be visually observed from the peripheral side.

4. The environmental test apparatus according to any one of claims 1 to 3, wherein the cylindrical portion has a bottom portion that narrows the suction side opening.

5. The environmental test apparatus according to any one of claims 1 to 4, wherein an opening is provided in the circumference of the cylindrical portion, and the area of the opening is changeable.

6. The environmental test apparatus according to any one of claims 1 to 5, wherein said blower is installed so as to be positioned in the central portion of the wall surface of said test chamber.

4. The environmental test apparatus according to claim 3 , further comprising operating means for changing the position and/or shape of said cylindrical portion.
