Description

本発明は、部屋等の換気に関する。 The present invention relates to ventilation of a room or the like.

一般的な住宅には、浴室やトイレなど、湿気や臭いがこもりやすく、充分な換気が必要で、さらに通常、ドアを閉めていることの多い部屋（以後「閉部屋」と呼ぶ）が存在する。 In a typical house, there are rooms such as bathrooms and toilets that tend to be damp and smelly, need adequate ventilation, and usually have doors often closed (hereinafter referred to as “closed rooms”). .

閉部屋には建築段階から電動換気扇やダクトなどの換気設備をもった場合もあるが、それらの設備を備えていない場合も多く、その場合、小さな窓が１つだけという場合が多いのが現状である。 Closed rooms may have ventilation equipment such as electric ventilation fans and ducts from the construction stage, but they are often not equipped with such equipment. In such cases, there are often only one small window. It is.

換気設備のない閉部屋は空気の循環が悪く、湿気や空気のにおいがこもりやすいなど空気の入れ替わりが少ない場合が多い。 Closed rooms without ventilation equipment often have poor air circulation, and there are many cases where the exchange of air is low due to the tendency of odors of moisture and air.

これにより、湿気を原因としたカビの繁殖や、臭いの定着につながる場合も多くある。 This often leads to mold growth and odor fixation due to moisture.

こういったカビや臭いは衛生的に良くない状況であることや、この閉部屋の使用時に使用者に対して不快感を与えることも多くある。 These molds and odors are often unsanitary and often cause discomfort to the user when using this closed room.

こういったカビや臭いを防ぐためには、充分換気を行うことが効果的である。「特許文献１」や「特許文献２」ような電動換気扇を据え付けるか、または、空気の出入りする窓をつくる方法、また、可能であれば、その両方を行うなどの方法が効果的である。 In order to prevent such mold and odor, it is effective to provide sufficient ventilation. A method of installing an electric ventilation fan such as “Patent Document 1” or “Patent Document 2” or a method of creating a window through which air enters and exits, and a method of performing both of them are effective.

浴室など湿気が多く充分な換気が必要な部屋でも、現実問題として、現在の段階で換気装置が付いていない状態の部屋に対して、電動換気扇など一般的な換気設備を取り付けるのは建物の工事や改装を伴うことから難しい場合が多い。 Even in a room with high humidity such as a bathroom where sufficient ventilation is required, as a practical matter, it is a construction work to install general ventilation equipment such as an electric ventilation fan in a room that does not have a ventilator at the current stage. It is often difficult because it involves renovation and renovation.

また、特に大規模集合住宅などでは、１方向の壁に、小さな明り取り兼用の窓を用意しているのみという場合も多く、１つの小窓のみでは、長い時間室内外の気圧差が発生し続けないことや、空気の出口と入り口の両方の働きをすることが１つの窓では難しいことなどから、空気の入れ替わりという現象が発生しにくく、換気能力がどうしても小さくなってしまう。 Also, especially in large-scale apartment houses, there are many cases where only a small light-sharing window is prepared on the wall in one direction. With only one small window, the atmospheric pressure difference between the room and outside continues for a long time. Since it is difficult to perform both functions of air outlet and entrance with a single window, the phenomenon of air exchange is unlikely to occur and the ventilation capacity is inevitably reduced.

そこで本発明は、閉部屋の窓を利用して効果的に寒気を行える事を目的とする。 SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to effectively cool air using a closed room window.

本発明の換気器具は、広い口を異なる方向に向けて配置された２つの漏斗状の空気取り入れ口と、窓の内側に向けて配置される２つの筒状の換気口と、前記２つの換気口のそれぞれの窓に向かう側の反対側に１方を接続して残る１方を前記２つの空気取り入れ口それぞれの狭い側の口に接続する２本のダクトと、前記２つの空気取り入れ口と前記２つの換気口と前記２つのダクトを固定する台座と、前記台座を窓枠に固定する固定具とを備える換気器具による換気 The ventilator according to the present invention includes two funnel-shaped air intake ports arranged with wide mouths oriented in different directions, two cylindrical ventilation ports arranged toward the inside of a window, and the two ventilations. Two ducts connecting one side to the opposite side of each side of the mouth facing the window and connecting the other side to the narrow side mouth of each of the two air intake ports, the two air intake ports, Ventilation by a ventilator comprising a pedestal for fixing the two ventilation openings and the two ducts, and a fixture for fixing the pedestal to a window frame.

本発明によれば、異なる方向を向いた２つの空気取り入れ口の開口部は、風などの自然の空気の流れ等により、その２つの開口部が互いに気圧差を生じやすく、窓の内側（室内）などのような気圧の変化の発生しにくい場所に対して、一方が正圧、もう一方が負圧の気圧をもつ可能性が高い。 According to the present invention, the openings of the two air intake ports facing in different directions are likely to cause a difference in atmospheric pressure between the two openings due to the flow of natural air such as wind. ) Etc., it is highly possible that one side has a positive pressure and the other has a negative pressure.

以下、本発明を具体化した形態を図面に基づいて説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

本発明の換気器具は、広い口を異なる方向を向けて配置された２つの漏斗状の空気取り入れ口と、窓の内側に向けて配置される２つの筒状の換気口と、２つの前記換気口のそれぞれの窓の内側に向く側の反対側に１方を接続され残る１方を２つの前記空気取り入れ口それぞれの狭い側の口を接続する２本のダクトと、これらを固定する台座と、前記台座を窓枠に固定する固定具を持つ換気器具を備え、異なる方向を向いた２つの空気取り入れ口の間で空気の流れにより気圧差が生じ、この気圧差により、窓の内側となる室内から２つの換気口とダクトを介して２つの空気取り入れ口との間で、空気の流れが生まれることにより、換気を効率よく行う。 The ventilator according to the present invention comprises two funnel-shaped air intakes arranged with different wide mouths oriented in different directions, two cylindrical ventilation ports arranged toward the inside of the window, and the two ventilations. One duct connected to the opposite side of each of the windows facing the inside of the window, the other one connecting the two narrow ducts of each of the two air intake ports, and a pedestal for fixing them , Provided with a ventilator having a fixture for fixing the pedestal to the window frame, and a pressure difference is caused by the flow of air between two air intake ports facing in different directions, and this pressure difference results in the inside of the window Ventilation is efficiently performed by creating an air flow between the two ventilation ports and the two air intake ports through the duct from the room.

本発明によれば、異なる方向を向いた２つの空気取り入れ口の開口部は、風などの自然の空気の流れ等により、その２つの開口部が互いに気圧差を生じやすく、窓の内側（室内）などのような気圧の変化の発生しにくい場所に対して、一方が正圧、もう一方が負圧の気圧をもつ可能性が高い。 According to the present invention, the openings of the two air intake ports facing in different directions are likely to cause a difference in atmospheric pressure between the two openings due to the flow of natural air such as wind. ) Etc., it is highly possible that one side has a positive pressure and the other has a negative pressure.

これは、小窓を境に一方の気圧が大きく変動する室外で、もう一方は変動する側の気圧の影響を受ける小部屋である場合、小部屋の気圧は気圧が大きく変動する室外の最大値と最小値の間となることと同じ原理である。 This is the outdoor maximum where the atmospheric pressure on one side is greatly fluctuating from the small window, and the other is a small room that is affected by the pressure on the fluctuating side. It is the same principle as being between and the minimum value.

室内から見た場合、この気圧差により、正圧となった側の空気取り込み口に接続されたダクト側の換気口では給気、負圧を持つ側の空気取り込み口に接続されたダクト側の換気口では排気という、空気の入れ替えに有効な２つの作用を併せ持つ働きをする。 When viewed from the inside of the room, due to this atmospheric pressure difference, the duct side ventilation port connected to the air intake port on the positive pressure side supplies air, and the duct side connected to the air intake port on the negative pressure side At the ventilation opening, it works to have two functions, effective for exchanging air, called exhaust.

その結果、２つの窓の付近に取り付けられた換気口の１方からは室内に向けて外気を吹き込み、もう１方の換気口からは室内の空気を屋外に吸い出す働きを持つ。 As a result, outside air is blown into one room from one of the ventilation openings installed near the two windows, and indoor air is sucked out from the other ventilation opening.

そして、この二つの換気口の働きは、風向きにより、２つの空気取り入れ口の気圧が逆になれば、逆の働きをもつことになる。 And these two vents work in reverse if the air pressure at the two air intakes is reversed due to the wind direction.

換気設備のない閉部屋では、図１４のような、小さな窓の換気能力は図１５の拡大図のように、多少の空気の入れ替わりはあるものの、部屋の中に空気が吹き込むような状況にはなりにくい。 In a closed room without ventilation equipment, the ventilation capacity of a small window, as shown in FIG. 14, is slightly changed as shown in the enlarged view of FIG. 15, but there is a situation where air blows into the room. Hard to become.

ここでは閉部屋を浴室２１として、窓が滑り出し窓形状の窓の場合の例を説明する。 Here, an example in which the closed room is the bathroom 21 and the window is a sliding window is described.

浴室２１に本発明の換気器具を図１のように取り付けた場合に、空気取り入れ口Ａ３と別方向を向いている空気取り入れ口Ｂ４は、その向きの違いから、自然の風が吹くことにより、２つの空気取り入れ口の間に気圧差が生じる。 When the ventilator of the present invention is attached to the bathroom 21 as shown in FIG. 1, the air intake B4 facing in a different direction from the air intake A3 is caused by the natural wind blowing from the difference in direction. There is a pressure difference between the two air intakes.

風が図１０のように左から吹く場合に、風上となる空気取り入れ口Ａ３の気圧は風向き（風上）２４の影響から上がる傾向となり、別方向を向いている空気取り入れ口Ｂ４は風向き（風下）２５の影響から気圧が下がる傾向にある。 When the wind blows from the left as shown in FIG. 10, the air pressure at the air intake A <b> 3 that becomes the windward tends to increase due to the influence of the wind direction (windward) 24, and the air intake B <b> 4 that faces in the other direction is the wind direction ( The air pressure tends to decrease due to the influence of 25 (leeward).

そのとき気圧が上がった空気取り入れ口Ａ３から空気取り入れダクトＡ５をとおり、換気口Ａ７から空気は吹き込んでくる。 At that time, air is blown from the ventilation port A7 through the air intake duct A5 from the air intake port A3 whose pressure has increased.

逆に気圧の下がった空気取り入れ口Ｂ４の影響で、換気口Ｂ８からは空気が換気状態となる。 On the contrary, the air is ventilated from the ventilation port B8 due to the influence of the air intake port B4 whose pressure has dropped.

また、図１２のように風の向きが逆になると、気圧の変化が図１０の場合と逆になり、気圧が上がった空気取り入れ口Ｂ４から空気取り入れダクトＢ６をとおり、換気口Ｂ８から空気は吹き込んでくる。 Further, when the direction of the wind is reversed as shown in FIG. 12, the change in the atmospheric pressure is opposite to that in FIG. 10, and the air is introduced from the air intake B4 through the air intake duct B6 and the air from the vent B8. Come in.

逆に気圧の下がった空気取り入れ口Ａ３の影響で、換気口Ａ７からは空気が換気状態となる。 On the contrary, the air is ventilated from the ventilation port A7 due to the influence of the air intake port A3 whose pressure has decreased.

図７は実施例１と同様な形状の換気器具を、内倒し窓形状の窓に取り付けた場合の図である。。 FIG. 7 is a view showing a case where a ventilator having the same shape as that of the first embodiment is attached to a window with an inside-down window shape. .

内倒し窓では、開口部が上部となるため、高い位置への取り付けとなるが、換気器具の影響で窓の明り取り性能が悪くなることも考えられるので、空気取り入れ口を図１の位置へ用意し、空気取り入れダクトを長くして、取り付け台座形状を変えることでの換気口を図７のような高い位置に配置することも有効な方法である。 In the case of an inward-facing window, the opening is at the top, so it will be installed at a high position. However, it is also possible that the light-clearing performance of the window will deteriorate due to the effects of ventilation equipment. It is also an effective method to arrange the ventilation port at a high position as shown in FIG. 7 by lengthening the air intake duct and changing the mounting base shape.

本発明は窓を持つが換気能力が低く、湿気や匂いの多い部屋に対して、窓を利用して換気を効率よく行う換気器具に掛かる発明である。 The present invention is an invention applied to a ventilator that efficiently ventilates a room having a window but having a low ventilation capacity and having high humidity and smell using the window.
