Description

  The present invention relates to a ventilation tile useful for ventilating an attic or the like and / or a ventilation device installed on the ventilation tile.

  In recent years, various measures and technologies have been promoted to reduce artificial energy consumption in order to reduce carbon dioxide emissions and dependence on fossil fuels such as oil on a global scale. Such measures are called “eco” measures, and various products that realize such measures are also called “eco” products. These measures are being promoted by the public and private sectors.

As part of the realization of such an “eco” measure, energy consumption can be reduced. Here, in ordinary houses, it is important to reduce energy consumption for cooling and heating the houses.
In a typical house, so-called tiles are laid on the roof.
As a function required for the tiled roof, a waterproof function against rainwater is required at the time of rainfall. Since the way of raining changes depending on the wind direction at the time of raining, etc., the method of howling the tiles is devised.

A typical house has a ceiling under the roof. Therefore, there is a space between the ceiling and the roof, and this space portion is generally called an attic. This attic space is usually filled with air, and the air itself has a low thermal conductivity, so this attic space functions as an insulation between the outside air and the space under the ceiling. Attic temperature and ventilation will play an important role.

  Specifically, because the amount of solar radiation that falls on the roof is large in summer, the temperature of the roof tiles is considerably higher than the outside air temperature, leading to an increase in the temperature of the attic space and the air itself. Although the thermal conductivity is low, the temperature of the indoor space under the ceiling will gradually increase, so ventilating the air in the attic space can prevent the temperature of the indoor space under the ceiling from rising. .

  On the other hand, in winter, heat in the indoor space under the ceiling can be prevented from being released to the outside air by not ventilating the space in the attic.

  From this point of view, a ventilator is installed in a part of the attic, and when the temperature of the attic becomes higher than the temperature of the attic, mainly using electricity as a power source, the ventilation fan is operated to ventilate the air in the attic. However, when the temperature is lower than a certain temperature, an attic ventilation device is known that prevents the heat in the indoor space under the ceiling from being released to the outside air without operating the ventilation fan.

  However, such an attic ventilation device consumes energy of electricity and is a mechanical part, and therefore requires maintenance.

Therefore, in view of such circumstances, the inventor does not require any artificial energy,
An attic ventilation device having a function that is cheaper and can be installed, ventilates the attic space in summer, and does not ventilate the attic space in winter, the ventilation tile with the attic ventilation device, Invented a ventilation tile device with an attic ventilation appliance and an attic ventilation method.

Although not shown, a stainless steel wire mesh can be easily attached to the second ventilation hole 104 by being fixed to the wire mesh attachment portion 240.

  FIG. 7 is an explanatory perspective view showing a state in which ventilation tiles on which the attic ventilation device according to the present invention is mounted are spread on the roof. The place where the ventilation tile to which the appliance for attic ventilation of the present invention is attached and the number of the ventilation tiles to be installed are effectively arranged in consideration of the shape of the individual roof and the area of the roof.

In summer and winter, the temperature of the tiled surface covered by the roof varies greatly, and the temperature of the attic space also varies considerably.Therefore, the first ventilation hole opening / closing part of the attic ventilation device is set according to the temperature of the attic space. By being able to open and close, efficient ventilation of the attic according to the temperature can be realized. In summer, the amount of solar radiation that falls on the roof is high, so the temperature of the roof tiles is considerably higher than the outside air temperature, leading to an increase in the temperature of the attic space, and the thermal conductivity of the air itself is low. Since the temperature of the indoor space under the ceiling is gradually increased, if the air in the attic space is ventilated, the temperature of the indoor space under the ceiling can be prevented from increasing. On the other hand, in winter, heat in the indoor space below the ceiling can be prevented from being released to the outside air by not ventilating the space in the attic. Also, in general Japanese houses, due to insufficient heat insulation and airtightness, in winter the room temperature rises due to heating, and the temperature of the attic space increases due to heat conduction and air convection in the room. As a result, the temperature drops at night after the room heating is turned off, which often causes condensation in the attic space, but depending on the temperature of the attic space, opening and closing the first ventilation hole of the attic ventilation device By being able to open and close the part, it is possible to prevent dew condensation by naturally ventilating the space in the attic, and the effect of enhancing the durability of the house can be expected.
Also, the amount of solar radiation that falls on the roof changes depending on the weather, and when it is clear, the amount of solar radiation that falls on the roof increases, so the tile surface temperature rises. Also, the temperature of the tile surface should be low. Therefore, a large difference in heat conduction from the tile surface also occurs depending on the weather, and the temperature of the attic space also changes. Therefore, when the weather is clear, the first ventilation hole opening / closing part of the attic ventilation device opens and closes according to the temperature to ventilate the air in the attic space, but when the rainfall is heavy, the temperature of the attic space is relatively low, so the attic It is considered that the first ventilation hole opening / closing part of the ventilation device is closed or the degree of opening is small, and this can be expected to prevent rainwater from entering the attic.

  FIG. 8 is an explanatory perspective view showing the configuration of a protection plate for field plate used when the roof tile with an attic ventilation device according to the present invention is applied to the roof. When roofing ventilation tiles with attic ventilation equipment on the roof, there are openings in the appropriate positions of the base plate where the ventilation tiles are to be spread and the resin underlayment called roofing that is affixed on the base plate. Although it is provided, it is assumed that rainwater enters the attic from the opening in the case of bad weather. Therefore, in order to prevent rainwater from entering the attic through the opening from the ventilation tile due to strong winds, heavy rain, etc., it is considered effective to protect the opening of the field board. Then, the inventor considered the method of installing the protection board for field plates for protecting the opening part of a field plate when installing a ventilation tile. In addition, because the roof tiles are ceramic, the position of the ventilation holes in the ventilation tube section differs slightly for each roof tile, but by using the field plate protection plate, the position of the ventilation holes and the opening of the field plate differ for each roof tile. Fine adjustment of the position alignment can be facilitated, and the work time for installing the ventilation tile device with attic ventilation equipment on the roof can be shortened.

  In FIG. 8, an arrow U indicates a water direction, and an arrow D indicates a water direction. The same applies to FIGS. FIG. 9 is an explanatory front view showing the configuration of the surface side (surface side in contact with the ventilation tile) of the protection board for the field board used when the ventilation tile with the attic ventilation device according to the present invention is applied to the roof. .

  As shown in FIG. 8, the protective plate for the field plate is made of stainless steel, and is composed of a first protective plate and a second protective plate, and the surface of the first protective plate that is not in contact with the second protective plate is It is in contact with a plastic underlay called roofing that is laid on a field board. Reference numeral 300 denotes a protection plate for a field plate, 310 denotes a first protection plate, and 320 denotes a second protection plate. The first protective plate 310 includes a first rectangular hole facing the opening of the field plate, and a rising edge toward the roof tile to prevent rainwater from entering the long side above the first protective plate 310 above the water. And a bent edge toward the base plate to prevent rainwater from entering the long side of the first rectangular hole on the water side. Reference numeral 311 denotes a first rectangular hole, 312 denotes a rising edge to the roof side provided on the long side on the water side of the first protective plate 310, and 313 denotes a long side on the water side of the first rectangular hole 311. It is a bending edge part to the field board side provided in (refer FIG. 11). Reference numeral 314 denotes a screw hole for installing the field plate protection plate on the field plate, and is provided at four locations around the corner of the first protection plate 310. In addition, in accordance with the position where the ventilation tile with the attic ventilation equipment is arranged, the opening of the field plate is placed at an appropriate position sandwiched between the roof tiles 410 (see FIG. 12) installed on the roofing laid on the field plate. The first protection plate 310 of the protection plate for the field plate is fixed on the opening 420 (see FIG. 12) of the field plate with screws or the like.

The second protective plate 320 is disposed on the first protective plate and has a second rectangular hole having a smaller opening area than the first rectangular hole and having a size included in the first rectangular hole. The second protective plate 320 has a structure that allows the second rectangular hole portion to slide left and right to adjust the position of the hole with respect to the first protective plate fixed on the field plate. Reference numeral 321 denotes a second rectangular hole portion, and reference numeral 324 denotes a screw hole portion for allowing the second protection plate 320 to slide left and right. As shown in FIG. Provided.
The reason for using the protection plate for the field plate with such a configuration is that the tile is a pottery, and therefore the position of the ventilation hole of the ventilation cylinder portion of the ventilation tile, in particular, the size and position of the first ventilation hole 101 is delicate for each tile. Different. For this reason, when installing ventilation tiles with attic ventilation equipment, it is not easy to align the position of the opening of the field plate and the ventilation holes of the ventilation tiles. In order to install ventilation tiles with attic ventilation equipment in the tiles of the roof, it is not easy to efficiently align the holes, but the second protection plate 320 of the field plate protection plate 300 is left and right. This is because it is possible to easily adjust the position of the first ventilation hole 101 that is different for each roof tile and to shorten the installation time.

The second protection plate 320 is provided with a saucer portion on the long side below the second rectangular hole portion 321 to prevent the rainwater entering from the second ventilation hole 104 from being frozen into the field plate as much as possible. The outer periphery has a rising edge toward the roof tile, has a shape that passes through the first rectangular hole and inclines toward the base plate, and further prevents the intrusion of rainwater from the second rectangular hole. It has a rising edge to the roof tile side on the outer peripheral part other than the long side under the water. 322 is a saucer part, 323 is a rising edge to the roof side provided on the outer periphery of the saucer part other than the long side under water, and 325 is other than the long side to which the saucer part 322 of the second rectangular hole 321 is attached. It is a rising edge to the tile side provided in the outer peripheral part of (see FIG. 11). In this way, when installing a roof tile with attic ventilation equipment on the roof, the position of the second rectangular hole can be easily adjusted according to the position and size of the first ventilation hole of the tile. By using the protection plate for the field plate, an effect of preventing intrusion from the opening of the field plate such as rainwater into the attic can be expected.
The reason for installing a rising edge on the outer circumference of the waterside other than the long side and not installing a rising edge on the waterside (mizumizu) is the reason for rainwater to the waterside (mizumizu). This is to prevent intrusion and to flow the water dammed from the rising edge on the outer periphery other than the long side under the water to the underwater side.

As shown in FIG. 11, the tray 322 passes through the first rectangular hole and is slightly inclined toward the base plate. Further, the outer periphery of the second rectangular hole 321 other than the long side where the tray 322 is installed is provided with a rising edge 323 toward the roof tile side. The shape of the tray 322 is merely an example, and is not limited to this, and may be any shape that is effective for preventing rainwater from leaking indoors through the first rectangular hole and the second rectangular hole. As shown in FIG. 11, the rising edge 312 of the first protection plate 310 on the long side of the water side to the roof side and the bending edge of the long side of the first rectangular hole 311 on the side of the base plate The shape of 313 is also effective for preventing rainwater from entering.
