【考案の詳細な説明】
［産業上の利用分野］
本考案は、室内の暖房及び冷房を行なう空調用
の吹出口であつて、特に室内壁上部に取り付けて
暖房時に温風を下向きに吹き出すことができるよ
うに構成した空調用吹出口の構造に関するもので
ある。[Detailed description of the invention] [Industrial application field] The present invention is an air conditioning outlet for heating and cooling a room, and in particular, it is installed on the upper part of an indoor wall to blow hot air downward during heating. The present invention relates to the structure of an air conditioning outlet configured to allow the following.
［従来技術とその問題点］
従来の空調用吹出口は、室内の天井近くに取り
付けられていると共に第２図に示すように、天板
０１と底板０２は平行で、この天板０１と底板０
２間に風向制御羽根０３を取り付け、この羽根０
３の角度を調節することによりその吹き出し方向
を制御している。[Prior art and its problems] In the conventional air conditioning outlet, the air outlet is installed near the ceiling of the room, and as shown in Fig. 2, the top plate 01 and the bottom plate 02 are parallel. 0
A wind direction control blade 03 is installed between 2, and this blade 0
By adjusting the angle of 3, the direction of the balloon is controlled.
このため、冷房時においては室内の上部に冷風
を水平に吹き出すために問題はないが、暖房時に
は次のような問題がある。 For this reason, there is no problem when cooling the room because the cold air is blown horizontally to the upper part of the room, but when heating the room there is the following problem.
ａ 比重の軽い温風は室内の床に向けて吹き出す
のが一般的であるが、この床に向けて温風を吹
き出すためには羽根０３を出来るだけ傾ける必
要がある。しかし、従来の羽根０３は10〜
20m／ｍの巾しかないために、水平の流れを床
側に向けるためにはその水平に対する角度を
60°前後まで傾ける必要がある。このため、吹
き出し時の抵抗が非常に大きくなり、風速が弱
まつて逆に床まで到達せず、垂直方向の温度分
布が悪いと共に暖房開始時に素早い暖房感を得
ることができない。a Generally, warm air with a light specific gravity is blown towards the floor of the room, but in order to blow out the warm air towards the floor, it is necessary to tilt the blade 03 as much as possible. However, the conventional blade 03 is 10~
Since the width is only 20m/m, in order to direct the horizontal flow toward the floor, the angle with respect to the horizontal must be adjusted.
It needs to be tilted to around 60 degrees. For this reason, the resistance when blowing air becomes very large, the wind speed becomes weaker and the air does not reach the floor, and the temperature distribution in the vertical direction is poor, and it is impossible to obtain a quick feeling of heating when heating starts.
ｂ 羽根０３を傾けた場合に吹出口の下縁が邪魔
になつてこれも吹き出しの抵抗を高める原因と
なつている。(b) When the blade 03 is tilted, the lower edge of the air outlet becomes a hindrance, which also causes an increase in the resistance to air blowing.
［本考案の目的］
本考案は、特に床に向けて温風を吹き出す際の
羽根及び吹出口の下縁が関係する抵抗を小さくし
て暖房感を早め、かつ室内の垂直方向の温度分布
を良くする空調用吹出口の構造を提案するのが目
的である。[Purpose of the present invention] The present invention reduces the resistance related to the blades and the lower edge of the air outlet when blowing hot air toward the floor, accelerates the feeling of heating, and improves the vertical temperature distribution in the room. The purpose is to propose an air conditioning outlet structure that improves the quality of air conditioning.
［本考案の構成及びその作用］
本考案は、上記目的を達成する手段として、吹
出口の下縁に沿つてスロープを設けると共に前記
スロープに平行な風向制御羽根の数を２〜３枚に
設定して成る空調用吹出口の構造を提案する。[Structure and operation of the present invention] As a means to achieve the above object, the present invention provides a slope along the lower edge of the air outlet and sets the number of wind direction control blades parallel to the slope to 2 to 3. We propose a structure for an air conditioning outlet made of:
上記構成において、羽根の巾は従来の場合に比
較して２〜３倍に設定してある。このため、羽根
を約45°に傾斜させて温風を吹き出すと、温風は
羽根に沿つて下向きに誘導され、然も羽根の角度
は小さく、この小さい分を羽根の巾を大きくする
ことにより温風を誘導するため、受ける抵抗は非
常に小さく、殆ど層流状となつて床に向けて流れ
る。この作用は吹出口の下縁にスロープが形成し
てあるためにより助長される。 In the above configuration, the width of the blade is set to be two to three times larger than that of the conventional case. For this reason, when the blades are tilted at an angle of about 45 degrees and hot air is blown out, the hot air is guided downward along the blades, but the angle of the blades is small, and this small amount can be compensated for by increasing the width of the blades. Since the hot air is guided, it encounters very little resistance and flows toward the floor in an almost laminar flow. This effect is further facilitated by the slope formed at the lower edge of the outlet.
なお、羽根の巾は吹出口の高さを２〜３等分し
たものとし、吹出口の下縁のスロープは45°〜60°
位が好ましい。羽根を４枚以上にすると、羽根の
巾は吹出口の高さの４分の１以下となり吹出方向
を床に向ける際にその水平に対する傾斜角度を
60°前後までとる必要があり、これが抵抗増の最
大の原因になる。このため、羽根の数は４枚以上
は好ましくない。又、羽根を１枚にすると、逆に
全風量が羽根に衝突し、ここで乱流を起すため、
抵抗が大きくなつてこの場合も好ましくない。 The width of the blade is the height of the outlet divided into 2 to 3 equal parts, and the slope of the lower edge of the outlet is 45° to 60°.
Preferably. If there are four or more blades, the width of the blade will be less than a quarter of the height of the air outlet, and when directing the air outlet toward the floor, the angle of inclination with respect to the horizontal will be adjusted.
It is necessary to take the angle up to around 60°, which is the biggest cause of increased resistance. For this reason, it is not preferable for the number of blades to be four or more. Also, if there is only one blade, the entire airflow will collide with the blade, causing turbulence.
This case is also unfavorable since the resistance increases.
［実施例及びその作用］
第１図は上記本考案の一実施例を示すもので、
１は吹出口全体、２は天板、３は底板、４は底板
３の前端を下方に向けて60°傾斜させたスロープ、
５は吹出口の天板２と底板３間において、水平方
向の支持により回転自在に取り付けられた風向制
御羽根にして、この羽根５は２枚から成り、羽根
５の巾はそれぞれ天板２と底板３間すなわち高さ
の約1/2である。[Embodiment and its operation] FIG. 1 shows an embodiment of the above-mentioned present invention.
1 is the entire air outlet, 2 is the top plate, 3 is the bottom plate, 4 is a slope with the front end of the bottom plate 3 tilted downward at 60 degrees,
Reference numeral 5 denotes a wind direction control blade which is rotatably mounted between the top plate 2 and the bottom plate 3 of the air outlet by horizontal support. It is between 3 feet of the bottom plate, or about 1/2 of the height.
なお、羽根５は水平に開いた際にその先端が吹
出口の正面から突出しないように支軸の位置が設
定されている。 Note that the position of the spindle of the blade 5 is set so that the tip thereof does not protrude from the front of the air outlet when the blade 5 is opened horizontally.
６は温風又は冷風が吹出口から出ないように遮
断する遮断装置である。 6 is a blocking device that blocks hot air or cold air from coming out of the outlet.
上記吹出口においては図のように羽根５を床側
に約45°傾斜させると、温風は羽根５及びスロー
プ４に沿つて下向きに層流状に吹き出しながら床
に届く。なお、羽根５の角度は、室内の広さ及び
吹出口の高さにより調整される。 In the above-mentioned air outlet, when the blades 5 are tilted at about 45 degrees toward the floor as shown in the figure, the warm air blows out laminarly downward along the blades 5 and the slope 4 and reaches the floor. Note that the angle of the blades 5 is adjusted depending on the size of the room and the height of the air outlet.
［本考案の効果］
本考案は、以上のように、吹出口の羽根を２〜
３枚に設定し、然も吹出口の下縁にスロープを形
成したので、羽根の角度をそれ程傾斜させなくと
も温風はスムーズに床に向けて吹き出す。[Effects of the present invention] As described above, the present invention has two to two blades at the air outlet.
Since the number of blades is set to three and a slope is formed at the lower edge of the air outlet, warm air is smoothly blown out towards the floor without having to tilt the angle of the blades that much.
この結果、羽根及び吹出口の下縁に起因する圧
力損失が小さく、効率的に温風を床に到達させる
ことができるので、暖房を入れた際に素早い暖房
感を得ることができると共に羽根の巾が大きいた
めに層流状に吹き出して室内の垂直方向の温度分
布を良くすることができる。 As a result, the pressure loss caused by the lower edges of the blades and the air outlet is small, and hot air can reach the floor efficiently, so when the heating is turned on, you can quickly feel the heating sensation, and the blades Since the width is large, the air can be blown out in a laminar flow to improve the vertical temperature distribution in the room.
