[Means for Solving the Problems] The means will be described below with reference to FIGS. 1 and 2. The sunshade structure 1 according to the present invention has a structure in which a plurality of evaporation holes 3 on the side surface thereof or a plurality of elongate evaporation grooves along the longitudinal direction thereof are separated from each other and the cylinders 2 are arranged in parallel. And 10mm or more 30m

A structure for inserting and fixing, a structure for additionally providing a water supply tank 7 on the side surface of the cylindrical upper support 5, and a water evaporation member 4
One end of the inside of the water tank, and an intermediate portion thereof is suspended in suspension grooves provided in the water tank upper end, the cylinder upper end, and the cylinder upper support 5, respectively, and the inside of the cylinder 2 extending from the middle portion is suspended. The water evaporating member 4 is arranged so that the middle portion thereof is along the longitudinal direction of the tubular body 2 and the other end is located below the tubular body.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION A plurality of evaporation holes 3 are formed on a side surface of a cylindrical body 2 which is one of the constituent elements of a sunshade structure 1 according to the present invention.
Alternatively, a plurality of elongated evaporation grooves are provided along the longitudinal direction. Here, the evaporation hole 3 or the evaporation groove is a passage for allowing outside air to flow into the cylindrical body 2 and discharging cool air generated in the cylindrical body to the outside of the cylindrical body. However, the transpiration holes 3 or the transpiration grooves are of a size and number sufficient to facilitate the inflow of outside air and the discharge of cold air. Here, the function of the cylindrical body 2 is to protect the water evaporation member 4 arranged in the cylindrical body and to prevent dust from adhering.

The cylindrical bodies 2 are separated from each other and arranged in parallel with each other. Here, the arrangement of the cylinders 2 is such that the upper cylinder support body 5 having openings provided at intervals of 10 mm or more and 30 mm or less and the cylinders having openings or recesses provided at intervals of 10 mm or more and 30 mm or less. This is done by inserting and fixing the upper end and the lower end of the tubular body 2 into the lower support 6. Here, the arrangement of the cylinders 2 is the cylinder 2
In case of arranging in one column, in addition to arranging in zigzag, it is also included in arranging in plural columns.

A water supply tank 7 is provided on the side surface of the cylindrical upper support 5.
Is attached. Here, the water supply tank 7 is a water tank for supplying water to the water evaporating member 4 arranged in the cylindrical body, and the water supply is performed at the upper portion of the water evaporating member 4 at the middle part of the water evaporating member 4 in the form of a strip. Suspended in the suspension grooves provided on the upper end of the body and the cylindrical upper support 5, respectively, one end of the suspension is submerged in the water tank, and water is sucked up to the suspension grooves by utilizing the capillary phenomenon, and then it is naturally dropped. This is done by spreading the water evaporation member 4 to the lower end or near the lower end. The water evaporating member 4 has its intermediate portion disposed in the upper end of the water supply tank, the upper end of the cylinder, and the suspension groove provided in the upper support 5 of the cylindrical body so that the size and direction of the water supply member 5 coincide with each other. The water evaporation member 4 is fixed by pressing the upper lid 8 of the water supply tank 7 that covers the body 5 and the upper end of the cylindrical body. Here, it is desirable that the water evaporating member 4 has a weight 9 attached so that one end of the water evaporating member 4 is stably submerged in the water tank.

In the cylindrical body, the water evaporating member 4 is arranged so that its intermediate portion is along the longitudinal direction of the cylindrical body 2 and the other end is located below the cylindrical body. Here, the water evaporation member 4 is the water evaporation member 4
Since it is a member for evaporating water contained in, it is preferable to use a polymer compound having a property of being easily adapted to water, that is, easily bonded to water. One of the preferable examples is a cotton cloth made of cellulose to which glucose is bound and sewn in multiple layers. The water evaporation member 4 preferably has a black color or a black color in order to further enhance energy absorption by receiving sunlight and solar heat.

[0010]

When one end of the water evaporating member 4 is submerged in the water supply layer, the water evaporating member 4 includes water in the water supply layer, and the water is capillarity to cause the upper end of the water supply layer, the cylindrical upper support 5 and the cylindrical body. It is sucked up to the suspension groove provided at the upper end. Here, since the suction height of water due to the capillary phenomenon is inversely proportional to the distance between the respective members constituting the water evaporation member 4, the smaller the distance, the higher the water suction height. By the way, the water level of the water injected into the water supply layer 7 is lowered by the water supply to the water evaporating member 4, but even if the water level is lowered, it is sufficient to suck up the water to the suspension grooves provided in each of them without being traced. The water vaporization member 4 used in the awning structure 1 according to the present invention is required to have a space of only this.

Water contained in the water evaporating member sucked up from the water supply layer 7 to the suspension grooves provided at the upper end of the water supply tank, the upper support member 5 and the upper end portion of the cylindrical member passes through the suspension grooves. After reaching the upper end of the cylinder, the gravity gradually falls from the upper end of the cylinder toward the lower end of the water evaporation member by gravity. However, in the process of the natural fall, the water contained in the water evaporation member 4 receives energy absorption by sunlight and solar heat and changes from a liquid phase to a gas phase, so-called water evaporation occurs. By the way, the heat of vaporization (also called heat of vaporization) Q when the water is vaporized
Varies depending on the temperature of evaporation, and Q [cal / gr] = 539.1-0.6 at t ° C. in the temperature range of 0 to 180 ° C.
428 (t-100) -0.000834 (t-10
0) given by ² . Here, when the temperature of the water contained in the water evaporation member 4 is 50 ° C., the heat of evaporation is t =
Substituting 50 gives a considerably large amount of heat of 569.16 cal / gr, and this amount of heat is deprived from the air present in the cylinder, so the temperature of the air inevitably drops. The temperature-decreased air becomes cold air and is pushed out of the cylinder through the evaporation hole 3 or the evaporation groove by the outside air flowing in from the evaporation hole 3 or the evaporation groove of the tube 2. However, as long as this phenomenon continues, cold air is continuously discharged to the outside of the cylinder, and the cold air diffuses toward the inside of the cylinder and the outside air toward the room that passes through the space between the cylinders. If the cold air is pushed indoors due to the circulation of, the indoor temperature will drop.

In the awning structure 1 according to the present invention, the water contained in the water evaporating member 4 naturally drops from the upper end of the cylinder toward the lower end of the water evaporating member 4 due to gravity, and the water evaporating member 4 It is required to evaporate the water contained in 4 and set the water surface of the water supply tank 7 at a position where the water does not drip from the lower end of the water evaporating member. This is because, if the water surface of the water supply tank 7 is considerably lower than the suspension grooves provided at the upper end of the water supply tank, the cylindrical upper support body 5, and the upper end of the cylindrical body, the water evaporation member 4 will reach the suspension groove by the capillary phenomenon. This is because it cannot be sucked up, and therefore water cannot be supplied to the water evaporation member 4 arranged in the cylinder. On the contrary, if the water surface of the water supply tank 7 is in the vicinity of the suspension groove, water will be sucked up excessively by the capillary phenomenon, and water will drip from the lower end of the water evaporation member 4 arranged in the cylinder. It is necessary to frequently fill the water tank 7 with water. By the way, since the amount of water evaporated from the water evaporating member 4 arranged in the cylinder varies depending on the outside temperature, humidity, wind speed, etc., the amount of water supplied from the upper end of the cylinder to the water evaporating member 4 is also the amount of water evaporation. It is necessary to make the total amount of water. Therefore, the amount of water can be adjusted by setting the height from the water surface in the water tank to the suspension groove within a predetermined range. Specifically, the length of the water evaporation member 4 made of laminated cotton cloth arranged in the cylinder is 1
In the case of 450 mm, the height from the water surface in the water supply tank 7 to the suspension groove can be reached within the range of 100 to 200 mm.

The factors that influence the amount of water evaporated from the water evaporation member 4 in the cylinder are the outside temperature, the humidity, the wind direction and speed, the ventilation of the cylinder, the water evaporation area, the water content of the water evaporation member 4, and the water. There is an energy absorption rate of the evaporation member 4 and the like. However, among these factors, the outside temperature, humidity, wind direction and wind speed cannot be artificially changed, but other factors can be artificially changed to some extent. That is, the ventilation of the cylindrical body 2 is set so that the evaporation holes 3 or the evaporation grooves provided in the cylindrical body 2 are sufficiently large in size and number, and the evaporation area of water is the water evaporation member 4
The length of the water vaporization member 4 is sufficient, and the water content of the water vaporization member 4 does not rise sufficiently in a short time when the water content of the water vaporization member 4 is sufficiently high. The absorptance can be reached to a considerable extent by applying black or a blackish color having a high energy absorptivity to the water evaporation member 4.

Next, as the water evaporating member 4 to be arranged in the cylinder, a strip of cotton cloth having a length of 1450 mm and a width of 22 mm in the cylinder is tripled and finely sewn in a straight line and zigzag with a sewing machine. Further, as another embodiment, a belt-shaped water evaporation member arranged in two rows at intervals in the cylinder is effective because the water evaporation area is enlarged and the water evaporation amount is increased accordingly. is there.

Since the water supply tank 7 attached to the side surface of the cylindrical upper support 5 needs to be large enough to supply water to the water evaporation member 4 for a long time, at least the internal capacity of 2 liters is required. Use one. Here, water injection into the water supply tank 7 is performed from a water injection port 10 provided in the upper lid 8 of the water supply tank 7.

[0018]

The first effect of the present invention is that, in addition to the blinding effect of the conventional blinds, the indoor temperature rise suppressing effect of the conventional blinds can be further increased without using any artificial energy. . Specifically, the effect of suppressing the temperature rise in the room varies depending on the outside temperature, but it is more remarkable as the outside temperature is higher, and when the outside temperature is 30 ° C. or higher, the present invention relates to the present invention at a point 100 mm outside of the conventional blind. The shade structure shows a lower value at least 3 ° C.
