Description

この発明は、エネルギーを使用して窓開口部の有る室内を冷暖房する時の冷暖房に必要なエネルギーを抑える省エネルギーを目的として、窓開口部の屋外側で、窓框もしくは外壁面に装着できる簡易型の窓カバーによる省エネルギーと窓開口部の室内側の結露防止に寄与する装置と使用方法に関する。 The present invention is a simple type that can be mounted on a window stile or an outer wall surface on the outdoor side of a window opening for the purpose of energy saving that suppresses the energy required for heating and cooling when heating and cooling a room having a window opening by using energy. The present invention relates to a device and a method of use that contributes to energy saving by the window cover and prevention of dew condensation on the indoor side of the window opening.

室内を冷暖房するときに外気温度と室内温度との間に温度差が有るために、冷房時には窓を通して温度の高い外気から室内に熱気が侵入し、暖房時には窓を通して温度の低い外気から室内に冷気が侵入してくるが、カーテンを閉めることでこの侵入熱を低減できることは広く知られている。しかし、カーテンを閉めただけでは、カーテンの上下左右に開いている壁面との隙間を通して室内空気が循環するために、窓とカーテンの間の窓際空間の空気が室内に入ることはあまり知られていない。 Since there is a temperature difference between the outside air temperature and the room temperature when heating and cooling the room, hot air enters the room from the hot outside air through the window during cooling, and cold air enters the room from the low temperature outside air through the window during heating. Is invading, but it is widely known that this invading heat can be reduced by closing the curtain. However, it is not well known that just by closing the curtain, the air in the window space between the window and the curtain enters the room because the indoor air circulates through the gaps between the wall surfaces that are open up, down, left and right. Absent.

この室内の空気の循環は対流と呼ばれ、冷房時には外気によって暖められた窓を通して室内の窓とカーテンの間の窓際空間の空気が暖められて上昇した後に、冷房により冷やされた室内空気がカーテンの下方から窓際空間に引き込まれることで、窓際空間の空気と室内空気の間に対流が起こり、暖房時には逆に、外気によって冷やされた窓を通して窓際空間の空気が冷やされて下降した後に、暖房により暖められた室内空気がカーテンの上方から窓際空間に引き込まれることで、窓際空間の空気と室内空気の間に対流が起こり、この空気の対流は室内温度と外気温度との温度差が有る限り継続するので、冷暖房時の大きなエネルギー損失になっている。 This circulation of air in the room is called convection, and when cooling, the air in the window space between the window and the curtain in the room is warmed and rises through the window warmed by the outside air, and then the indoor air cooled by the cooling is curtained. By being drawn into the window space from below, convection occurs between the air in the window space and the indoor air, and conversely during heating, the air in the window space is cooled and lowered through the window cooled by the outside air, and then heated. The indoor air warmed by the above is drawn into the window space from above the curtain, causing convection between the air in the window space and the indoor air, and this air convection is as long as there is a temperature difference between the indoor temperature and the outside air temperature. As it continues, it causes a large energy loss during heating and cooling.

また、冬季においては、窓の室内側での結露が大きな問題となっている。窓の室内側における結露の原因は、仕切られていない室内空間内では水蒸気の絶対圧力がどこでも概ね一定で有ることに対して、空気中の水蒸気の飽和蒸気圧は温度が下がるに従って低くなることから、外気温度が下がり室内の窓際の空気の温度が下がるに従い窓際の空気中の水蒸気の飽和蒸気圧が下がり、室内空気の水蒸気の絶対圧力より窓際の空気中の水蒸気の飽和蒸気圧が低くなると、窓際の空気中の水蒸気は水蒸気のままでは居られなくなり温度の低いところから順に凝縮して結露となる。 Moreover, in winter, dew condensation on the indoor side of the window has become a big problem. The cause of dew condensation on the indoor side of the window is that the absolute pressure of water vapor is almost constant everywhere in the unpartitioned indoor space, whereas the saturated vapor pressure of water vapor in the air decreases as the temperature decreases. As the outside air temperature decreases and the temperature of the air near the window in the room decreases, the saturated vapor pressure of the water vapor in the air near the window decreases, and when the saturated vapor pressure of the water vapor in the air near the window becomes lower than the absolute pressure of the water vapor in the room air, The water vapor in the air near the window cannot stay as it is, and condenses in order from the lowest temperature to form dew.

一般的なカーテンは、光を通さないものであっても通気性はある程度有るので、水蒸気は自由に通り抜けることができるため、水蒸気に対しては仕切りが無いに等しいことになり、カーテンを閉めて空気を遮蔽して省エネルギーを行うことで、窓際の空気の温度がカーテンで仕切らない時より下がって外気温度に近づくことになるので結露し易くなる。 Even if a general curtain does not allow light to pass through, it has some air permeability, so water vapor can pass through freely, which means that there is no partition against water vapor, and the curtain is closed. By shielding the air to save energy, the temperature of the air near the window will be lower than when it is not partitioned by the curtain and will approach the outside air temperature, so condensation will be more likely to occur.

かかる問題を解決するため、例えば、特許文献1には外壁全体を断熱性の有る回動可能な構造体で覆うことで、省エネルギーと結露を防止する装置が開示されているが、既設の建物に追加設置するにはコストと手間が掛かるため導入は困難である。 In order to solve such a problem, for example, Patent Document 1 discloses a device for saving energy and preventing dew condensation by covering the entire outer wall with a rotatable structure having heat insulating properties, but in an existing building It is difficult to introduce it because it takes cost and labor to install it additionally.

特許公開文献1には、窓開口部の屋外側に上下左右の窓枠に固定する形で設置するロールスクリーンの設置方法が開示されているが、設置工事と機器の費用が高価になるので普及させることは困難である。 Patent Publication Document 1 discloses a method of installing a roll screen that is fixed to a window frame on the top, bottom, left, and right on the outdoor side of a window opening, but it is widely used because the cost of installation work and equipment is high. It is difficult to make it.

実用新案公開文献1には、窓の全面を屋外から覆う防護スクリーンを窓の屋外側に装着することで、窓の屋外側に閉鎖された空間を保持する方法が開示されているが、前記同様、設置工事と機器の費用が高価になるので普及させることは困難である。 Utility model publication document 1 discloses a method of maintaining a closed space on the outdoor side of a window by attaching a protective screen that covers the entire surface of the window from the outside to the outdoor side of the window. , Installation work and equipment costs are high, so it is difficult to popularize.

既設の一般的な窓開口部は、一般的な外壁と比べて断熱性能が極端に悪いので、建物の省エネルギーを考える上で一番対策が必要な箇所である。一般的な窓とカーテンという組み合わせの窓開口部では、窓の開閉とカーテンの開閉でしか外部からの侵入熱を抑えることができないために現状のままでは限界が有る。 The existing general window opening has extremely poor heat insulation performance compared to the general outer wall, so it is the place where the most measures are required when considering energy saving of the building. With a window opening that is a combination of a general window and a curtain, the heat entering from the outside can be suppressed only by opening and closing the window and opening and closing the curtain, so there is a limit as it is.

窓開口部の屋外側に雨戸が有る場合には、これを閉めることで省エネルギーと室内側の結露防止に寄与できるが、雨戸が光を通さないので昼間に使用するには適さない。 If there is a shutter on the outdoor side of the window opening, closing it can contribute to energy saving and prevention of dew condensation on the indoor side, but it is not suitable for use in the daytime because the shutter does not allow light to pass through.

窓開口部に窓とカーテンだけの部屋を冷暖房する時に、カーテンを閉めても外気温度と室内温度との温度差が有る為に、冷房時には窓際空間の空気が暖められて比重が軽くなり上昇して壁面とカーテン上部の隙間から室内に侵入した後に、室内の冷房で冷やされた空気が壁面とカーテン下部の隙間から窓際空間に引き込まれ、それがまた暖められて上昇して室内に侵入してという空気の対流が起こり、暖房時には逆に、窓際空間の空気が外気温度により冷やされて下降して、壁面とカーテン下部の隙間から室内に侵入した後に、室内の暖房で暖められた空気が壁面とカーテン上部の隙間から窓際空間に引き込まれ、それがまた冷やされて下降して室内に侵入してという空気の対流が起こり、この空気の対流は室内温度と外気温度との温度差が有る限り継続されるので、この空気の対流を止めることができれば省エネルギーとなる。 When heating and cooling a room with only windows and curtains at the window opening, there is a temperature difference between the outside air temperature and the room temperature even when the curtains are closed, so the air in the window space is warmed during cooling and the specific gravity rises. After entering the room through the gap between the wall surface and the upper part of the curtain, the air cooled by the indoor cooling is drawn into the window space through the gap between the wall surface and the lower part of the curtain, and it is warmed up again and invades the room. On the contrary, when heating, the air in the window space is cooled by the outside air temperature and descends, and after entering the room through the gap between the wall surface and the bottom of the curtain, the air warmed by the indoor heating flows to the wall surface. As long as there is a temperature difference between the room temperature and the outside air temperature, air convection occurs in which the air is drawn into the window space through the gap above the curtain, which is then cooled and descends into the room. Since it will continue, if this air convection can be stopped, energy will be saved.

さらに、冬季は外気温度が下がるために絶対湿度が下がり乾燥しやすくなるために、室内では乾燥防止のために加湿することが多くなり、外気温度が下がる夜間に窓開口部の室内側で結露が発生することが大きな問題となっている。 Furthermore, in winter, the outside air temperature drops, which lowers the absolute humidity and makes it easier to dry. Therefore, it is often humidified indoors to prevent drying, and condensation forms on the indoor side of the window opening at night when the outside air temperature drops. It is a big problem to occur.

本発明は、窓開口部の屋外側において、窓框もしくは外壁面に後付けで簡単に設置できる開閉可能な窓カバーと、その設置方法を提供する。この窓カバーを閉じることにより、窓開口部の屋外側に概ね閉じられた空間を創設することができる。 The present invention provides an openable and closable window cover that can be easily retrofitted to a window stile or an outer wall surface on the outdoor side of a window opening, and an installation method thereof. By closing the window cover, a substantially closed space can be created on the outdoor side of the window opening.

窓開口部の屋外側で窓框もしくは外壁面に後付けで簡単に設置できる窓カバーにより、窓開口部の屋外側に概ね閉じられた空間を創設することにより、その空間を空気の断熱層として利用することで、窓開口部の室内側の結露防止と、冷暖房時の省エネルギーを図ることができる。 By creating a nearly closed space on the outdoor side of the window opening with a window cover that can be easily retrofitted to the window stile or outer wall surface on the outdoor side of the window opening, that space can be used as an air insulation layer. By doing so, it is possible to prevent dew condensation on the indoor side of the window opening and save energy during heating and cooling.

本発明に係る後付けの屋外側の窓カバーについて、図面に基づいて実施の形態を説明する。なお、以下の図面において同一または相当する部分には同一の参照符号を付しその説明は繰り返さない。 An embodiment of the retrofitted outdoor window cover according to the present invention will be described with reference to the drawings. In the following drawings, the same or corresponding parts are designated by the same reference numerals, and the description thereof will not be repeated.

図1は、後付けの屋外側の第一実施形態の窓カバーの設置状態を示す正面図であり、図2は、図1に1点鎖線X−Xで示す位置で水平に切断した水平断面図である。さらに、図3は、図1に1点鎖線Y−Yで示す位置で垂直に切断した垂直断面図である。 FIG. 1 is a front view showing an installed state of the window cover of the first embodiment on the outdoor side of the retrofit, and FIG. 2 is a horizontal cross-sectional view taken horizontally at the position indicated by the alternate long and short dash line XX in FIG. Is. Further, FIG. 3 is a vertical cross-sectional view taken vertically at the position indicated by the alternate long and short dash line YY in FIG.

屋外側の第一実施形態の窓カバーは、左右の固定軸ボックス1を取付ネジ7を使用して窓框11に固定し、その間にカバーシート4を左右の固定軸2に掛けて張り巡らせ、上下を閉鎖ボックス3で抑えて使用することを特徴とする。 In the window cover of the first embodiment on the outdoor side, the left and right fixed shaft boxes 1 are fixed to the window stile 11 by using the mounting screws 7, and the cover sheet 4 is hung on the left and right fixed shafts 2 in the meantime. It is characterized in that the upper and lower parts are suppressed by the closing box 3 for use.

図1では、カバーシート4を上の閉鎖ボックス3cから外して少し下げた状態を示しているが、この窓カバーを使用する時には、カバーシート4を上の閉鎖カバー3cまで上げて使用し、使用しない時には、カバーシート4を下まで下ろせば良いが、反対に、カバーシート4を上の閉鎖ボックス3cで固定して、下の閉鎖ボックス3dから外して上に上げても良い。 FIG. 1 shows a state in which the cover sheet 4 is removed from the upper closing box 3c and slightly lowered. However, when using this window cover, the cover sheet 4 is raised to the upper closing cover 3c and used. When not, the cover sheet 4 may be lowered to the bottom, but conversely, the cover sheet 4 may be fixed by the upper closing box 3c, removed from the lower closing box 3d, and raised upward.

カバーシート4は、ロールスクリーンの様に一方に巻き取る様式でも良いが、蛇腹状に折り曲げて片側に寄せる様にしても良い。 The cover sheet 4 may be wound on one side like a roll screen, or may be bent in a bellows shape and brought closer to one side.

図2及び図3に示すように、張り巡らせたカバーシート4に対して、左右の固定ボックス1及び上下の閉鎖ボックス3が線で接触する様に抑えることにより、カバーシート4の四方が固定ボックス1及び閉鎖ボックス3を介して窓框と四方で繋がることになり、カバーシート4と窓の間の空間を外気と概ね遮蔽することができるので、この遮蔽された空間が遮蔽された空気層となり断熱に寄与することができる。 As shown in FIGS. 2 and 3, the left and right fixing boxes 1 and the upper and lower closing boxes 3 are suppressed so as to be in line contact with the stretched cover sheet 4, so that the four sides of the cover sheet 4 are fixed boxes. Since it is connected to the window sill on all sides via 1 and the closing box 3, the space between the cover sheet 4 and the window can be substantially shielded from the outside air, and this shielded space becomes a shielded air layer. It can contribute to heat insulation.

この空気層は、四方を閉じられている方が空気の出入りが完全に無くなるので望ましいが、この空気層への出入りが温度差による対流により起こることを想定すると、上下の閉鎖ボックス3は、上下共に有ることが望ましいが、上もしくは下のどちらか一方しかなくても、左右を閉じていれば対流を止めることができ遮蔽された空気層として同様の省エネ効果が期待できる。 It is desirable that this air layer is closed on all sides because the inflow and outflow of air is completely eliminated. However, assuming that the inflow and outflow to this air layer is caused by convection due to a temperature difference, the upper and lower closed boxes 3 are moved up and down. It is desirable to have both, but even if there is only one of the upper or lower, convection can be stopped if the left and right are closed, and the same energy saving effect can be expected as a shielded air layer.

図3では、閉鎖ボックス3がカバーシート4を挟む様にして固定しているが、カバーシート4との接触が閉鎖ボックス3の両端まで繋がっていれば空気を通さないので、挟まずに抑えるだけでも使用できるが、外気の風によりカバーシート4が波打つことが有ると接触が離れる恐れが有るので、少なくとも上下のどちらか一方は挟む様に固定した方が良い。 In FIG. 3, the closing box 3 is fixed so as to sandwich the cover sheet 4, but if the contact with the cover sheet 4 is connected to both ends of the closing box 3, air does not pass through, so it is only suppressed without sandwiching. However, if the cover sheet 4 is wavy due to the wind of the outside air, the contact may be separated. Therefore, it is better to fix at least one of the upper and lower sides so as to sandwich it.

図4は、固定ボックス内で固定軸2にカバーシート4を繋ぐ方法を示し、伸縮自在の輪ゴム状の留めリング5を固定軸2に通し、留めリング5に取り付けたクリップ6でカバーシート4の端を挟んで固定する固定形態を示しており、このリング5とクリップ6とを併せた長さが長過ぎると、カバーシート4の端が固定ボックス1内に留まらなくなり、固定ボックス1とカバーシート4との線的接触が途切れることになるので注意がいる。 FIG. 4 shows a method of connecting the cover sheet 4 to the fixed shaft 2 in the fixed box. A stretchable rubber band-shaped fastening ring 5 is passed through the fixed shaft 2, and a clip 6 attached to the fastening ring 5 is attached to the cover sheet 4. It shows a fixed form in which the end is sandwiched and fixed. If the combined length of the ring 5 and the clip 6 is too long, the end of the cover sheet 4 does not stay in the fixing box 1, and the fixing box 1 and the cover sheet are fixed. Note that the linear contact with 4 will be interrupted.

カバーシート4の端をクリップ6で固定する方法にすることで、カバーシート4を自在な長さにカットして使用することができ、窓開口部の幅に左右されない。 By fixing the end of the cover sheet 4 with the clip 6, the cover sheet 4 can be cut to a free length and used, and is not affected by the width of the window opening.

屋外側に窓カバーを設けて外気と窓12の間に遮蔽された空気層ができることで、冷暖房において窓開口部の省エネ効果が期待できるとともに、冬季の外気温度が下がった場合においては、屋外側の窓カバーが無い時に比べて窓12の温度を高く保つことが可能となり、窓開口部の室内側の結露防止の効果が期待できる。 By providing a window cover on the outdoor side to form a shielded air layer between the outside air and the window 12, the energy saving effect of the window opening can be expected in heating and cooling, and when the outside air temperature in winter drops, the outdoor side It is possible to keep the temperature of the window 12 higher than when there is no window cover, and the effect of preventing dew condensation on the indoor side of the window opening can be expected.

図5は、窓開口部の屋外側の第二実施形態の窓カバーの斜視図であり、一般的な水平の窓格子の格子部分の後ろにシート状のカバーを組み込んだもので、釣りバンド206にて窓カバーを開けた状態で固定したところであり、正面から見ると水平の窓格子に見える窓カバーの斜視図である。 FIG. 5 is a perspective view of the window cover of the second embodiment on the outdoor side of the window opening, in which a sheet-shaped cover is incorporated behind the grid portion of a general horizontal window grid, and the fishing band 206 It is a perspective view of the window cover that looks like a horizontal window grid when viewed from the front, where the window cover was fixed in the open state.

図6は、窓開口部の屋外側の第二実施形態の窓カバーを使用しないで開けている時の外壁面に直交する垂直断面図である。この状態の時には格子部分を庇として利用できるので、夏季の昼間の日除け効果が期待できる。 FIG. 6 is a vertical cross-sectional view orthogonal to the outer wall surface when the window cover of the second embodiment on the outdoor side of the window opening is opened without being used. In this state, the lattice part can be used as an eave, so a daytime awning effect in summer can be expected.

図7は、窓開口部の屋外側の第二実施形態の窓カバーを使用するために閉めている時の外壁面に直交する垂直断面図である。図6の窓カバーを開けている状態から、窓カバー固定軸204を中心に概ね90度回動させて、窓カバーのカバーシート202の上下の端部が重なる様に連なって閉じた状態となり、窓カバーのカバーシート202と窓の間の空間を外気と概ね遮蔽することができるので、この遮蔽された空間が遮蔽された空気層となり断熱に寄与することができる。 FIG. 7 is a vertical cross-sectional view orthogonal to the outer wall surface when the window cover of the second embodiment on the outdoor side of the window opening is closed. From the state in which the window cover of FIG. 6 is opened, the window cover fixed shaft 204 is rotated about 90 degrees, and the upper and lower ends of the window cover cover sheet 202 are connected and closed so as to overlap each other. Since the space between the cover sheet 202 of the window cover and the window can be substantially shielded from the outside air, this shielded space becomes a shielded air layer and can contribute to heat insulation.

図8は、図9の既設の屋外用の風を通さないロールスクリーン装置の風を通さないロールスクリーン301を改造して、窓開口部の屋外側に概密閉された空気層を作る場合の、風を通さないロールスクリーン301を所定の位置まで降ろして、閉鎖カバー304との間のファスナー305を下から嵌めて、上まで閉じた状態の第三実施形態の窓カバーの正面図である。FIG. 8 shows a case where the wind-impermeable roll screen 301 of the existing outdoor air-impermeable roll screen device of FIG. 9 is modified to form a generally sealed air layer on the outdoor side of the window opening. It is a front view of the window cover of the third embodiment in a state where the airtight roll screen 301 is lowered to a predetermined position, the fastener 305 between the closing cover 304 and the closing cover 304 is fitted from below, and the roll screen 301 is closed to the top.

図9は、既設の屋外用の風を通さないロールスクリーン装置の風を通さないロールスクリーン301を冷房時に日射遮蔽を目的として使用する時の、風を通さないロールスクリーン301を途中まで降ろした設置状態を示す正面図である。FIG. 9 shows an installation in which the wind- impermeable roll screen 301 is halfway lowered when the wind-impermeable roll screen 301 of the existing outdoor air-impermeable roll screen device is used for the purpose of shielding sunlight during cooling. It is a front view which shows the state.

図9の風を通さないロールスクリーン301を日射遮蔽できる位置まで降ろしているだけでは、風を通さないロールスクリーン301の両サイドには窓框11との間に隙間が開いているので、窓開口部の屋外側と風を通さないロールスクリーン301の間の空気は、風を通さないロールスクリーン301を左右に横切るように、又は、横から下に流れ落ちるように流れるので、密閉された空気層としての機能は働かない。If the wind-impermeable roll screen 301 of FIG. 9 is simply lowered to a position where it can shield the sunlight, there are gaps between the roll screen 301 and the window stile 11 on both sides of the air-impermeable roll screen 301. air between the roll screen 301 impervious to weather side and wind parts are across the rolling screen 301 impervious to wind on the left and right, or, since the flows from the side as run off down as sealed air layer Function does not work.

一方、図8に示す第三実施形態の窓カバーは、風を通さないロールスクリーン301の両サイドに各々ファスナー305の片一方を取り付け、各々のファスナー305の他方を風を通さないロールスクリーン301の左右に配置した閉鎖カバー304に取り付け、風を通さないロールスクリーン301を窓開口部が閉止できる所定の位置まで降ろした後に、この風を通さないロールスクリーン301の両サイドの各々のファスナー305の片一方と、左右に配置した各々の閉鎖カバー304に取り付けた各々に対応するファスナー305の他方とを各々下で繋いだ後に、各々のファスナー305を上に上げて、左右の閉鎖カバー304と風を通さないロールスクリーン301とを上下方向に全面的に繋いだ状態を示す正面図である。On the other hand, in the window cover of the third embodiment shown in FIG. 8, one of the fasteners 305 is attached to both sides of the roll screen 301 that does not allow air to pass through , and one of the fasteners 305 is impermeable to the other side of the roll screen 301. attached to the closure cover 304 disposed on the left and right, after unloading the roll screen 301 that is impervious to air to a predetermined position of the window opening can be closed, pieces of both sides of each of the fastener 305 of the rolling screen 301 impervious to the wind After connecting one and the other of the corresponding fasteners 305 attached to each of the left and right closing covers 304 underneath, each fastener 305 is raised up to blow the left and right closing covers 304 and the wind. It is a front view which shows the state which the roll screen 301 which does not pass through is totally connected in the vertical direction.

この図8に示す第三実施形態の窓カバーは、左右の閉鎖カバー304と風を通さないロールスクリーン301をファスナー305にて接続固定して、概密閉された空気層を創設することを特徴とする。Window cover of the third embodiment shown in FIG. 8, and characterized in that the roll screen 301 impervious closure cover 304 and wind the right and left connecting fixed by fasteners 305, to establish an air layer which is approximate sealed To do.

図8では、正面から見て風を通さないロールスクリーン301を窓開口部の下方が完全に隠れる所定の位置まで降ろしてから、左右にあるファスナー305を用いて風を通さないロールスクリーン301と左右にある閉鎖カバー304とを下で接続して後に各々のファスナー305を下から上に繋ぎながら上げて行き、ロールスクリーンボックス302の下辺より上まで完全に上げている状態を示し、風を通さないロールスクリーン301を使用した窓開口部の屋外側を全面的にカバーした窓カバーの実施形態となる。In Figure 8, since the lower the rolling screen 301 impervious to wind as viewed from the front to a predetermined position where downward completely hidden in the window opening, a shade 301 which is impervious to air by using a fastener 305 to the left and right lateral each of the fasteners 305 go up while connecting from bottom to top and a closure cover 304 in the later connected below, shows a state in which fully raised to above the lower side of the roll screen box 302, impervious to air This is an embodiment of a window cover that completely covers the outdoor side of the window opening using the roll screen 301.
