Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an insulating air intake member that is attached to the upper part of the ventilation wall or ventilation roof of an air cycle house.

(Prior art and problems) In air cycle houses, ventilation walls or ventilation roofs made of insulation boards are installed on the inside of the building's exterior walls or under the roof at a distance from the exterior walls, etc. By introducing natural ventilation into the ventilation layer formed between the ventilation wall, etc., or by allowing the air within this ventilation layer to absorb solar heat through the wall or roof, etc., the air flow within the ventilation layer can be stopped or stopped. Control and adjust the temperature and humidity of the building. In such houses, when air warmed by solar heat in the ventilation layer is introduced into the interior space of the building during the day in winter, or when outside air taken in from under the floor is passed through the ventilation layer in summer, the ventilation layer is usually used. As seen in the wall example in Figure 7, an air intake opening B is provided at the top of the ventilation wall A, from which air is allowed to naturally flow into the internal space of the building.

However, if the air intake port B at the top of the ventilation wall is constructed as described above, the intake port B will be connected to the ventilation layer C.
Since the opening area of the intake port B is perpendicular to the intake port B, there is a problem that the upward air current cannot smoothly flow into the interior space of the building unless the opening area of the intake port B is increased.

Furthermore, heat conduction insulation is insufficient in the vicinity of such air intake openings, and radiant heat from the interior space of the building is large, resulting in poor heat retention of the building. In particular, when the outside temperature drops, dew condensation E occurs on the back surface of the outer wall D, etc. facing the air intake opening B, which accelerates the decay of the building.

In view of these points, the present invention allows the air in the ventilation layer to smoothly flow into the interior space of the building without making the air intake port on the upper part of the ventilation wall of the air cycle house so large. An object of the present invention is to provide a heat insulating air intake member for an air cycle house, which can improve the heat insulation near the intake and make this type of house system function more efficiently.

(Means for solving the problem) In order to achieve the above-mentioned purpose, the insulating air intake member of the present invention is made entirely of a heat insulating material such as expanded styrene, and is used for ventilation of air cycle houses. A main body that can be fitted into an opening provided at the top of a wall or ventilation roof, an upper brim that protrudes toward the front of the main body on the top surface of the main body, and a rear side of the main body on the bottom surface of the main body. The air flows inside the main body through a protruding lower flange, an air inlet formed at the lower corner of the front of the main body, and an air outlet formed at the upper corner of the back of the main body. It includes a communication path that communicates the inlet and the air outlet, a front radiation prevention wall provided above the inlet on the front of the main body, and a rear radiation prevention wall provided below the outflow port on the back of the main body. , the air inlet is opened toward the ventilation layer of the air cycle house, the air outlet is opened toward the interior space of the air cycle house, and the air outlet is opened toward the interior space of the air cycle house; The stepped portion formed by the upper edge of the opening of the ventilation wall is locked to the upper edge of the opening of the ventilation wall, etc., while the stepped portion formed by the front surface of the lower brim and the bottom surface of the main body is locked to the lower edge of the opening of the ventilation wall. It is characterized by being locked in.

A step different from the step may be formed in the thickness direction on the front surface of the lower flange, and this may be secured to the lower edge of the opening of the ventilation wall or the like.

(Function) When this insulated air intake member is installed in the opening provided at the top of the ventilation wall of an air cycle house, the inlet, communication path, and outlet of the main body are diagonally upward relative to the ventilation layer. Since the inclined flow path is formed, the air rising in the ventilation layer is naturally led to the interior space of the building through this flow path, even if the opening is not very large.

In addition, this air intake member is formed using a heat insulating material such as expanded styrene, and is installed in close contact with an air inflow opening such as a ventilation wall, so that the heat conduction insulation properties of the ventilation wall are lost. do not have. At the same time, since radiation prevention walls are formed on the front and back sides of the main body of the air intake member, it is possible to block heat dissipation due to radiation from inside the building. Moreover, as mentioned above, the openings of the inlet and outlet are not large, and the channel connecting them is long and slopes diagonally upward, so the heat dissipated by radiation from inside the building through the channel is small ( The amount of radiant heat dissipated is inversely proportional to the square of the distance).

Furthermore, if a step is formed on the front surface of the lower flange, it becomes possible to mount the insulation board according to the thickness of the insulation board constituting the ventilation wall or the like.

Reference numeral 1 in the figure is the main body of this air intake member, which is made of a heat insulating material such as expanded styrene and has a shape and size that can be fitted into an opening provided at the top of a ventilation wall, etc. . An air inlet 2 is provided at the lower end corner of the front of the main body that faces the inner surface of the outer wall when installed, and an air outlet 3 is provided at the upper end corner of the back of the main body that faces the interior space of the building during installation. It is provided along the width direction of the main body part 1. Reference numeral 4 denotes an upwardly inclined communication path that communicates the inlet 2 and the outlet 3 inside the main body. The upper part 5 of the main body extends from the inlet 2 to the outlet 3 via the communication path 4.
The lower part 6 of the main body functions as a front radiation prevention wall and a rear radiation prevention wall, respectively, and shields heat radiation from the inside of the building such as a ventilation wall to the ventilation layer during use.

Reference numeral 7 designates an upper flange portion for mounting that is integrally provided on the upper surface of the main body portion 1 and is integrally provided with the main body portion 1. This upper brim portion 7 is provided along the width direction of the main body portion 1, and both ends thereof are attached to the main body portion 1 as they are. A side flange 8 is formed by falling down along the side surface of the portion 1 . If the main body portion 1 is reliably fitted into the opening, the side flange portions 8 are not necessarily required.

Reference numeral 9 designates a lower flange portion for attachment that protrudes from the bottom surface of the main body portion 1 in the same manner as the upper flange portion 7.

To explain the installation state of this air intake member with reference to FIGS. 3 and 4, first, an air inflow opening 13 of a predetermined size is formed in the insulation board that is the ventilation wall 12 or the ventilation roof 16. After opening with a cutter or the like and applying adhesive to the back of the upper collar 7 and the front of the lower collar 9, insert the lower collar 9 into the opening from the front side of the ventilation wall, etc., and then insert the lower collar 9 into the opening. The front side of 9 is fixed to the back side of the ventilation wall 12, etc., and the back side of the upper brim part 7 is fixed to the front side of the ventilation wall 12, etc., respectively. Next, the outer wall 17 or the like or the plywood 18 or the like is assembled from the front side of the air intake member to form the ventilation layer 19 between the ventilation wall 12 or the like and the outer wall 17 or the like.

In addition, FIG. 5 shows a conceptual configuration diagram of the installation position of this air intake member and the air flow state in an air cycle house. In the figure, reference numeral 20 indicates the air intake member, and 21 is an air damper attached to the lower part of the ventilation wall 12 or the ventilation roof 16, and air flows into the ventilation layer 19 from the internal space 23 of the building. However, it has a valve 22 that prevents leakage from inside the ventilation layer 19 to the internal space 23 of the building.
