Description

  The present invention uses a net installed in order to find a vine plant planted outdoors in a building such as a school building having an opening / closing window, and causes the liquid heat to flow down at that time. This is a technology related to a green water curtain that lowers the air temperature and sends it as cold air from the open / close window to the room.

  In recent years, summer heat has become unbearable year by year due to the effects of global warming. For this reason, in the summer, the air temperature must be utilized to lower the room temperature and live, and the amount of power used tends to increase.

  Moreover, since the air conditioner exhausts high-temperature air to the outside through the heat exchanger, the air-conditioner is in a vicious cycle of further increasing the outdoor temperature that is covered with concrete and causing the heat island phenomenon.

On the other hand, in Patent Document 1 below, a window portion of a building that can effectively reduce the amount of heat flowing into the room through the opening / closing window of the building, bring the room to a comfortable temperature, and improve the cooling efficiency. A thermal insulation apparatus is disclosed.
JP-A-5-113081

  However, the technique disclosed in Patent Document 1 is provided with a spray pipe for allowing cold water to flow down in the upper frame body of the window frame, and a liquid collecting tank for collecting the water reaching the lower frame body into the waste liquid pipe. By providing it on the body, it is intended to reduce the amount of heat flowing into the room, and there is a disadvantage that the structure is very complicated and the installation cost increases.

  In view of the above-mentioned problems found in the prior art, the present invention is simple in structure and can be installed at a low cost by simply reducing the temperature of the air flowing in from the opening / closing window using heat of vaporization. Also aimed at providing an inexpensive green water curtain.

  The present invention has been made to achieve the above-mentioned object, and includes a water-exuding pipe laid horizontally above the opening / closing window of a building, and a water supply pipe connected to the water-extracting pipe to supply the liquid. The liquid exudation pipe is held by the upper edge portion, and the lower edge portion is fixed to the ground side, and is configured with a net body that is freely installed to entangle vines planted outdoors, The net body is most characterized in that the flow of the water that oozes out from the water ooze pipe is freely knitted.

  The mesh is preferably knitted by changing the mesh size so that the upper mesh is minimum and the lower mesh is maximum. In this case, the minimum mesh area of the mesh is It is desirable to provide an overlapping portion extending so as to cover the upper edge of the mesh area of the next mesh size at the edge.

  Further, the net body is formed by knitting a chain of a large number of ring portions to maintain a high tensile strength, and a large number of warp portions arranged in the left-right direction, and a thread-like fiber bundled so as to be rich in water retention. Skew yarns that are knitted with a large number of weft yarns that are inserted from the lateral direction into the individual loops of the warp yarns and arranged in the vertical direction, or that the surface regions excluding the minimum mesh region are arranged to cross each other. It can be organized as a part.

  According to the present invention, since it is possible to obtain a cold wind effect by air cooled by the heat of vaporization when the water liquid flows down the net body, it is possible to exhibit an excellent cooling effect that is friendly to the environment.

  FIG. 1 is a schematic side view of an example of the present invention. FIG. 2 is an explanatory view showing an example of a water / liquid brewing pipe constituting the present invention, in which (a) shows an overall perspective view and (b) shows an exploded perspective view of a main part.

  According to these drawings, the entire green water curtain 11 is connected to the water leaching pipe 12 laid horizontally above the opening / closing window 52 of the building 51, and supplies water liquid by being connected to the liquid oozing pipe 12. The water supply pipe 22 and the liquid exudation pipe 12 hold the upper edge portion 33 and the lower edge portion 34 is fixed on the ground 55 side so that the vine plant 57 planted outdoors can be freely entangled. And a net 32.

  Among these, for example, the water exudation pipe 12 formed using “irrigation porous pipe drip tube” manufactured by Kakudai Co., Ltd. has an appropriate length determined in relation to the specific situation of the building 51 to be installed. For example, it is formed as shown in FIG. In addition, when it is necessary to make the liquid effluent pipe 12 longer and horizontally mounted, as shown in FIG. 2 (b), a plurality of liquid effluent pipes 12 are connected to a connecting socket 13 having a length of 60 mm, for example. It can respond by connecting via. Note that the end of the water leaching pipe 12 is closed with a water stop lid 14.

  The water supply pipe 22 made of a flexible hose or the like has a start end side connected to a water tap or the like (not shown), and a terminal end side connected to the start end side of the water leaching pipe 12 via a fastening material 23.

  On the other hand, the net body 32 knitted using polyester fibers or the like is knitted with a large number of warp yarn portions 35 arranged in parallel and a large number of weft yarn portions 37 arranged in parallel. Moreover, the mesh body 32 is knitted by changing the mesh size so that the upper mesh 38 is minimum and the lower mesh 38 is maximum as shown in FIG.

  The mesh sizes in this case are as follows. Each mesh size of the surface area shown as A in FIG. 1 and FIG. 3 is 1 mm, for example, the surface area shown as B is 3 mm, the surface area shown as C is 6 mm, for example. For example, the mesh size becomes larger as it goes down, such as 10 mm. When it is necessary to make the longitudinal length of the net 32 longer in relation to the building 51, the surface area shown as D in FIG. 3 is further divided into two, and the mesh size of the lower surface area is divided. Can be appropriately changed as desired, for example, 30 mm. The mesh body 32 can gradually increase the thickness of the warp yarn portion 35 and the weft yarn portion 37 as the mesh size increases. In addition, the code | symbol 39 in FIG. 1 shows the stitching | suture part formed in each boundary area | region which differs in mesh size.

  Further, the surface area of the minimum mesh size indicated as A in the mesh body 32 covers the upper edge portion 47 of the surface area of the next mesh size indicated as B in order to contribute to the smooth flow of the permeated water liquid. The overlapping portion 46 extended in this manner can be provided on the lower edge portion 45 side.

  In this case, as shown in FIG. 4, the mesh body 32 is knitted in a chain shape in which a large number of ring portions 36 are connected to maintain a high tensile strength, and a large number of warp portions arranged in tandem in the left-right direction. 35 and a large number of weft yarn portions 37 arranged in a row in the vertical direction by inserting thread-like fibers such as polyester fibers bundled so as to be rich in water retention ability into the individual ring portions 36 of the warp yarn portions 35 from the transverse direction. It is preferable to do this. In addition, the code | symbol 37a in FIG. 4 shows the fixation part with respect to the warp yarn part 35 located in the outermost side.

  FIG. 5 is a front view showing another example of the net 32 corresponding to FIG. According to the figure, the mesh body 32 has a surface area indicated as B excluding the minimum mesh area indicated as A, with one skewed yarn portion 43 and the other skewed yarn portion 44 arranged so as to cross each other. It is organized under a certain positional relationship.

  In this case, the minimum mesh area indicated as A in the mesh body 32 has an overlapping portion 46 extended so as to cover the upper edge 47 of the mesh area of the next mesh size indicated as B. 45 side. In this example as well, the net 32 can be knitted under a mesh size as shown in FIG. 3 or a knitting structure as shown in FIG. 4 can be adopted.

  Further, the net body 32 knitted in this manner is wound with the vinyl auxiliary cover 16 after the upper edge portion 33 is wound around the aqueous liquid exuding pipe portion 12 by two or more turns as shown in FIG. By doing so, it is integrated with the liquid exudation pipe part 12 side. The exposed surface of the auxiliary cover 16 can be covered with a plastic cover.

  Further, the liquid exudation pipe portion 12 around which the mesh body 32 is wound is disposed in the building 51 after attaching the hooks 17 such as S-shaped hooks to a plurality of places with an interval of about 300 to 400 mm, for example. It can be placed horizontally by hooking each latching piece 18 such as a latching ring. In addition, attachment of the water-liquid leaching pipe portion 12 is performed in an arrangement relationship in which the auxiliary cover 16 faces the building 51 side.

  In this way, the net 32 having the upper edge portion 33 held on the side of the water-exuding pipe portion 12 is driven by a pile on the side of the planter 56 having a heavy weight, such as made of concrete, placed on the ground surface 55. Thus, the position of the lower edge 34 can be fixed. The net body 32 can be fixed in position by using a pile on the ground 55 side directly on the lower edge 34 side.

  Next, the operation and effect of the present invention having the above-described configuration will be described. The liquid exudation pipe portion 12 around which the upper edge portion 33 of the mesh body 32 is wound and the auxiliary cover 16 is attached is provided with a water supply pipe on the start end side. Then, the latching tool 17 is latched on the latching piece 18 on the upper side of the opening / closing window 52 of the building 51, and is placed horizontally.

  In addition, the upper edge portion 33 of the net body 32 is planted with a vine plant 57 such as a morning glory in a state in which an inclination angle with an internal angle θ of, for example, 70 to 80 degrees is secured with the ground 55 side. The position is fixed using a pile or the like on the concrete planter 56 side, and the entire net 32 is installed under the state shown in FIG.

  After the installation of the net 32 is finished in this way, the aqueous liquid is supplied to the aqueous liquid exuding pipe portion 12 from the water tap side or the like via the water supply pipe 22. The supplied aqueous liquid in the aqueous liquid exuding pipe portion 12 gradually begins to exude from the peripheral surface side, and flows down toward the net 32 while being guided by the inner side surface 17a of the auxiliary cover 17.

  Since the mesh body 32 is knitted by changing the mesh size so that the upper mesh 38 is the smallest and the lower mesh 38 is the largest, the entire area of the mesh body 32 is made while flowing more and faster. It is possible to keep a lot of water.

  In addition, the net 32 has a maximum lower mesh 38 of, for example, 30 mm, so that even the vine plant 57 that has not been sufficiently grown can be entangled with certainty.

  For this reason, if the green water curtain 11 is formed by using the net 32 around April-May, the vine plant 57 does not reach the position covering the open / close window 52, and is due to global warming around late May. Even if it reaches midsummer day, the air passing through the mesh 38 is cooled by about 4 to 5 ° C. as a result of taking away the heat of vaporization when the flowing liquid evaporates, and flows into the room from the opening / closing window 52 as cold air. I can do it.

  In addition, when the vine plant 57 has sufficiently extended to a position covering the open / close window 52, it can effectively block the summer sun, and it can also be caused by the heat of vaporization when the liquid falls down the net 32. The cool air effect by the chilled air can be obtained at the same time, and an excellent environmentally friendly cooling effect can be exhibited.

  The above is the description of the present invention based on the illustrated examples, and the specific contents thereof are not limited thereto. For example, the net 32 can be installed using not only a two- and three-story building 51 such as a school but also a narrow space such as a veranda. The mesh size of the mesh body 32 may be, for example, six or more sizes determined by the relationship with the height of the building. Further, the net body 32 can be knitted under other appropriate knitting patterns in addition to the lattice shape shown in FIG. 1 and the diamond shape shown in FIG. The knitting structure of the net body may be knitted like a normal net other than the illustrated example.
