Description

  The present invention relates to a ventilation device for a wooden house, and more particularly to a mounting structure of an air supply device in a forced ventilation system.

  The ventilation system in a detached wooden house has natural ventilation and forced ventilation, but in a recent wooden house with high airtightness, an exhaust device equipped with a fan device is provided at an appropriate location in the house, and no fan device is provided. Provide an appropriate number of air supply devices (for example, outside air introduction pipes) and perform 24-hour ventilation with gentle air supply / exhaust.

  FIG. 6 shows an example of a ventilation system in a wooden house, where an exhaust device 2 for forced ventilation is arranged at an appropriate location of the house 1 and an air supply device 4 for introducing outside air is arranged at a plurality of locations. To do.

  Reference numeral 6 denotes a duct (exhaust pipe) for sending indoor air taken from the air supply device 4 to the exhaust device 2. The duct 6 is arranged in the ceiling / under the floor / the back of the hut. In the case where it can be shared, for example, room air that has entered from a plurality of air intakes 5 is sent to the exhaust device 2 via a single shared duct 6-1. You may send to the exhaust apparatus 2 via the independent duct 6-2.

  Conventionally, as shown in FIG. 7, the air supply device 4 is provided so as to protrude (expose) to the outdoor side of the outer wall decorative material (exterior material) 7 (for example, Patent Documents 1 and 2 below). Reference numeral 4-1 denotes an outdoor air intake unit on the outdoor side, 4-2 denotes a pipe material, and 4-3 denotes an outdoor air discharge unit on the indoor side. In some cases, the outside air intake section 4-1 is provided with a filter material for avoiding the entry of dust and insects.

  8 is a foundation, 9 is a base, 11 is a pillar (a pillar of a frame), 12 is a floor (floor structure), 13 is an interior material (inner wall structure), 14 is a torso, 16 is an interior material 13 It is a receiving material.

  The problem is that the exterior wall decorative material 7 is soiled by condensation by exposing the outside air intake portion 4-1 of the air supply device 4 to the outdoor side.

  Although the air supply device 4 arranged on the first floor portion is illustrated in FIG. 7, since the air supply device 4 is also arranged on the second floor portion, when the outer wall (7) becomes more dirty, the entire house looks dirty.

  Since the exhaust device 2 performs exhaust for 24 hours by a small motor (for example, a DC motor or the like), normally, no condensation occurs around the outside air intake portion 4-1. However, when the air pressure is unstable (strong wind), or when the exhaust device 2 has stopped operating due to long-term going out / power failure, etc., the indoor air flows out through the outside air intake section 4-1. In this case, warm air (room air) and cold air (winter outside air) are mixed to form dew and stain the outer wall (7).

  Therefore, an object of the present invention is to prevent the outer wall (outer wall decorative material) from being soiled by the air supply device in the forced ventilation system.

  In order to achieve the above object, a ventilator for a wooden house according to the present invention is technically premised on a ventilator for a wooden house that includes an exhaust device that includes a fan device and an air supply device that does not include the fan device. As described above, the outside air intake portion of the air supply device is provided in a clearance portion between the column member of the housing and the outer wall decorative material.

  If an outside air intake is provided in the clearance (gap) between the columnar pillar and the outer wall decorative material, the outside air intake will be covered with the outer wall decorative material, so it will be affected by changes in atmospheric pressure (strong winds, etc.) Even if the exhaust system is not affected, condensation is less likely to occur.

  Even if condensation occurs, the surface of the outer wall decorative material is not soiled. For this reason, the beauty of the wooden house can be guaranteed for a long time.

  The outside air intake portion of the air supply device is formed into a box-like body having a vertical surface substantially parallel to the outer wall decorative material, and an air intake opening is provided on at least one of the side, top, and bottom surfaces of the box-like body There is a case (Claim 2).

  Although the width dimension of the clearance part between the pillar material of the frame and the outer wall decorative material is small (narrow), the outside air intake part of the air supply device is formed into a box-like body having a vertical surface substantially parallel to the outer wall decorative material. Thus, it is possible to easily install the outside air intake portion in the narrow gap.

  Further, by providing an air intake opening in at least one of the side surface, the upper surface, and the lower surface of the box-shaped body, even when the vertical surface substantially parallel to the outer wall decorative material and the outer wall decorative material are approaching / contacting each other Stable air intake is possible.

  In some cases, the structural plywood is disposed on the outdoor side of the columnar material of the housing, and the outside air intake portion of the air supply device is disposed in the clearance portion between the structural plywood and the outer wall decorative material.

  In order to increase the earthquake resistance of wooden houses, structural plywood may be placed on the outdoor side of the pillars of the frame. In this case as well, air is supplied to the clearance (gap) between the outer wall decorative material and the pillars. By arranging the outside air intake part of the device, the surface contamination of the outer wall decorative material is prevented. You may arrange | position a heat insulating material or / and a structural plywood between the pillar materials which comprise a housing.

  According to the configuration of the present invention, the surface fouling of the outer wall decorative material due to the air supply device in the wooden house using the forced ventilation system can be prevented.

It is a top view which shows the ventilation apparatus of the conventional wooden house. It is a longitudinal cross-sectional view which shows the air supply apparatus which concerns on FIG.

  FIG. 1 shows a ventilation device for a wooden house according to the present invention.

  This ventilation device is provided with an exhaust device 31 having a fan device at an appropriate location of a house (wooden house) 30, and constantly discharges the air inside the house 30 to the outside while supplying air into the appropriate location of the house 30. A device 40 is provided.

  32 is an outer wall body, 33 is an outer wall decorative material, 34 is a partition wall, 35 is an air intake for exhausting indoor air, etc., and 36 is a duct (exhaust gas) for sending indoor air to the exhaust device 31. Dedicated pipe). The configuration will be specifically described below.

  As the exhaust device 31, it is desirable to use a motor with low power consumption and quiet operation noise, such as a DC motor. Exhaust capacity should just be the thing which can replace the air in the house 30 in total, for example in 24 hours. It may be a type that can switch the displacement in several steps.

  The exhaust port 31-1 of the exhaust device 31 is preferably disposed so as to protrude from the outer wall decorative material 33 to the outdoor side. 31-2 is a connector (pipe connection part) for connecting the exhaust device 31 and the duct 36.

  A plurality of connectors 31-2 are preferably provided. This is because the duct 36 may not be shared depending on the structure of the house 30 or the like, and common / independent ducts are often mixed. The duct 36 for discharging the air in the house 30 to the outdoors is disposed at an appropriate location that is not exposed to the living room, for example, under the floor / behind the ceiling.

  As shown in FIG. 2, the air supply device 40 includes, for example, an outdoor-side outdoor air intake unit 41, a pipe material 42, and an indoor-side outdoor air discharge unit 43. Unlike the exhaust device 31, a motor device for forcibly sucking outside air is not required, but a motor device for forcibly sucking outside air may be mounted.

  As for the outer wall of the house 30, for example, a trunk rim 32-2 is arranged on the outdoor side of a pillar material (including a stud) 32-1 constituting the outer wall main body 32, and this trunk rim 32-2 (for example, disposed in the lateral direction). The outer wall decorative material 33 is disposed on the outdoor side of the horizontal trunk edge.

  30-1 is a foundation, 30-2 is a base, 30-3 is a floor (floor structure), 30-4 is an interior material (for example, gypsum board / interior decorative material, etc.), 30-5 is a torso, 30-6 Is a receiving material for the interior material 30-4.

  Since the trunk edge 32-2 is provided, a clearance portion (gap due to the inclusion of the trunk edge) 32-4 is generated between the pillar material (including the intermediate pillar) 32-1 and the outer wall decorative material 33.

  The outside air intake portion 41 of the air supply device 40 is arranged in a clearance portion 32-4 between the column material (including the intermediary column) 32-1 and the outer wall decorative material 33.

  For example, as shown in FIG. 3, the outside air intake portion 41 is preferably formed into a thin box-like body having a vertical surface 41-1 substantially parallel to the outer wall decorative material 33. Then, for example, an air intake opening 41-3 is provided on the side surface / upper surface 41-2 of the box-like body, and a filter for preventing intrusion of dust, insects, or the like is provided in the portion. The shape of the vertical surface 41-1 may be any of a rectangle, a circle, and a polygon other than a rectangle. An air intake opening may be provided on the lower surface.

  The trunk edge 32-2 for fixing the outer wall decorative material 33 may be a horizontal trunk edge (see FIG. 2) or a vertical trunk edge (see FIG. 4).

  The outside air discharge portion 43 provided on the indoor side can also have a configuration substantially similar to that of the outside air intake portion 41. This is because by supplying air from the side surface (41-2) of the box-shaped body, the air flow can be relaxed (softened) compared to supplying air from the vertical surface (41-1).

  As shown in FIG. 4, for example, the outer wall main body 32 of the house 30 is preferably provided with a heat insulating material 32-7 between a pillar material (including an intermediate pillar) 32-1 and a pillar material 32-1. As the heat insulating material 32-7, for example, glass wool can be used. It is desirable to use so-called high performance glass wool having a low thermal conductivity. Glass wool is inexpensive and has a stable market supply. As the heat insulating material 32-7, a polystyrene-based material can also be used. However, in addition to requiring a fireproof coating, there are difficulties such as easy contraction due to aging.

  When high performance glass wool is used as the heat insulating material 32-7, for example, a moisture permeable waterproof sheet 32-8 is disposed on the outdoor surface, and a moisture-proof confidential film 32-9 is disposed on the indoor surface. desirable. The moisture-permeable waterproof sheet 32-8 and the moisture-proof confidential film 32-9 may be made of different materials or the same material. The trunk edge 32-2 shown in FIG. 4 showed the longitudinal trunk edge distribute | arranged to the vertical direction along the pillar material 32-1. This is to make the arrangement structure of the air supply device 40 clearer.

  The width dimension of the clearance part 32-4 on the back side of the outer wall decorative material 33 formed by the trunk edge 32-2 is, for example, 10 mm to 20 mm.

  In FIGS. 2 and 4, it is illustrated that there is a slight gap between the outside air intake portion 41 arranged in the clearance portion 32-4 and the back side of the outer wall decorative material 33, but the outside air intake portion 41 presenting a box-like body. When the air intake opening 41-3 is provided on the side surface 41-2 (see FIG. 3), there may be no gap between the outside air intake 41 and the back side of the outer wall decorative material 33.

  Although the arrangement | positioning location of the air supply apparatus 40 is not specifically limited, It is desirable to arrange | position for the place which uses a fire (thing with a direct open flame, such as a boiler / kerosene stove) for external air supply. In particular, the kitchen / bathroom preferably supplies the outside air directly by the air supply device 40.

  Therefore, according to such a configuration, in the ventilation system (forced ventilation) that compensates the negative pressure in the house 30 caused by the operation of the exhaust device 31 by introducing the external air through the air supply device 40, the outside air intake portion of the air supply device 40 41 is provided in the clearance portion 32-4 on the back side of the outer wall decorative material 33, so that the surface contamination of the outer wall decorative material 33 due to condensation of ventilation air can be prevented, and the appearance beauty of the house can be ensured for a long time.

  Further, since the outside air intake 41 is located on the back side of the outer wall decorative material 33, it prevents the strong indoor air from flowing in during strong winds and prevents rainwater from entering the house during heavy rainfall such as typhoons. Comfort can be secured.

  By forming the outside air intake portion 41 of the air supply device 40 into a box-like body having a vertical surface substantially parallel to the outer wall decorative material 33, the outside air intake portion 41 can be easily installed in a narrow gap (clearance portion 32-4). I can do it.

  Further, by providing the air intake opening 41-3 on the side surface 41-2, the gap between the outer wall decorative material 33 and the back surface of the outer wall decorative material 33 is narrow, and for example, even when it is close / contacted, a sufficient amount of outside air is stabilized. Can be incorporated.

  The housing (especially the outer wall) of the house 30 may be a traditional frame construction method or a framed wall structure (including a 2 × 4 construction method). The frame wall structure is an outer wall structure that enhances the seismic performance of the frame by arranging an appropriate number of frames (frame members) between the base 30-2 and the trunk difference 30-5.

  FIG. 5 shows an outer wall structure in which a structural plywood 50 is provided on the outdoor side of a pillar material (including a spacer) 32-1 to enhance the seismic performance of the frame.

  The structural plywood 50 is fixed to the pillar member 32-1 through a nail 51, for example. The interior material 30-4 is also fixed through, for example, a nail 51.

  Also in this case, the outer wall decorative material is provided by arranging the outside air intake portion 41 of the air supply device 40 in the clearance portion 32-4 between the pillar material (including the intermediate pillar) 32-1 and the back surface of the outer wall decorative material 33. 33 surface contamination can be prevented. It is preferable to arrange high-performance glass wool (heat insulating material; not shown) between the column material (including the intermediate column) 32-1 and the column material (including the intermediate column) 32-1.

  The structural plywood 50 enhances the seismic performance of the housing, but has almost no air permeability. Therefore, a hole (not shown) for disposing (installing) the air supply device 40 is provided, and the pipe material 42 is provided in the hole. When mounting, it is not always necessary to fill a delicate gap between the hole and the pipe material 42 (for example, caulking).

  The gap formed between the hole provided in the structural plywood 50 and the outer periphery of the pipe material 42 may be filled. However, the structural plywood 50 originally has high airtightness, and an excessively high airtight state is not preferable. Since there is a design philosophy, it is preferable to individually handle / construct.

  In addition, it is preferable that the pipe member 42 constituting the air supply device 40 has a so-called telescopic structure that can be expanded and contracted in order to be able to flexibly cope with the width dimension of the outer wall main body 32.

  In the above description, the air supply device 40 is illustrated as being disposed near the floor (floor structure) 30-3 (see FIG. 2). However, it is desirable to design the height position of the air supply device 40 individually based on the live activity line in the bathroom / kitchen / room, etc., and it is not always necessary to position the outside air discharge unit 43 at a location close to the floor. Absent.

  However, more preferably, the outside air discharge portion 43 of the air supply device 40 and the air intake 35 for exhausting air such as indoors are arranged at diagonal positions in the vertical direction in a room including a bathroom. This is because the air in the room or the like can be replaced without stagnation.
