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 such a viewpoint, a ventilation device 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 and the air in the attic is discharged. Attic ventilation devices are known that ventilate and prevent the heat in the indoor space under the ceiling from being released to the outside air without operating the ventilation fan when the temperature is below a certain temperature.

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

Therefore, in light of the circumstances concerned, the inventor does not need any artificial energy,
More inexpensive, installable, ventilating the attic space in the summer, and not ventilating the attic space in the winter, an attic ventilation appliance, and a ventilation tile with the attic ventilation appliance The ventilation tile device with the attic ventilation appliance was devised.

The opening on the back of the tile is covered with the attic ventilation device. The attic ventilation device is made of stainless steel, and although not shown, a stainless steel wire mesh can be attached to the second ventilation hole 104.

  As shown in FIG. 2, the main body 210 has a shape similar to the first ventilation hole 101 of the ventilation tile 100, and the first ventilation hole opening / closing part 220 includes an opening provided in the main body 210 and the opening. A lid portion installed on the ventilation passage side of the lid portion, and a spring holding portion for fixing the spring portion.

  The spring portion 223 is made of a shape memory alloy that contracts and expands depending on the temperature around the spring. The lid portion 222 contracts when the temperature around the spring portion 223 is high, and the lid is opened. On the contrary, when the temperature around the spring portion 223 is low, the spring portion is extended and the lid is closed. The attic ventilation device of the present invention can naturally ventilate the attic through the opening of the field plate and the first ventilation hole opening / closing portion of the attic ventilation device by expansion and contraction of the spring made of shape memory alloy. And

  In summer and winter, the temperature of the tiled roof is greatly different and the temperature of the attic space is also quite different, so the opening can be opened and closed according to the temperature of the attic space, so that the attic according to the temperature Efficient ventilation 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, depending on the weather such as sunny days and rainy days, the temperature of the attic space varies depending on the amount of solar radiation, so the temperature of the attic space also differs, and the spring expands and contracts according to the temperature of the attic space to open the opening It is possible to select whether to ventilate by opening and closing, and on rainy days it is possible to close the opening and not ventilate.

  The partition part 230 is formed on one side of the main body part 210 so as to be substantially vertical, and has a shape similar to the vertical surface of the ventilation tile weir part 103 with respect to the ventilation passage. Closely fixed.

  The wire mesh mounting portion 240 is an elongated rectangular plate that is fixed at one end to the partition 230 and reaches the second ventilation hole 104, and the end that is not fixed is bent to close the second ventilation hole 104. It is possible to attach a wire mesh. Reference numeral 241 denotes an elongated arm portion of the wire mesh mounting portion 240, and reference numeral 242 denotes an end portion of the arm portion 241 that is not fixed and is bent. A hole 242 is provided to fix a stainless steel rainwater intrusion prevention wire mesh by screwing. Although the stainless steel wire mesh is omitted in FIG. 2, it is convenient for preventing invasion of small animals such as rainwater and reeds.

  When roofing ventilation tiles with attic ventilation equipment on the roof, openings are provided in the base plate at the position where the ventilation tiles are to be spread and the resin underlaying material called roofing that is affixed on the base plate, It is also assumed that rainwater enters the attic from the opening. Therefore, it is necessary to protect the opening on the field plate in order to prevent rainwater from entering the attic from the ventilation tile through the opening due to strong winds or heavy rain. Therefore, the inventor devised a device that uses a protective plate for field boards when installing ventilation tiles. In addition, since the roof tile is a ceramic, the position of the ventilation hole in the ventilation tube portion differs slightly for each roof tile. However, the position of the hole can be adjusted by using a field plate protection plate.
