Description

  The present invention relates to a building ventilation unit that can be easily installed in a building without deteriorating the appearance of the building.

  In order to improve the external appearance of a building, a ventilation unit has been proposed in which a louver for ventilation is integrated with a gutter provided at the top of a window (Patent Document 1).

This consists of a small girdle part on the outdoor side, a horizontal part that penetrates the wall of the building, and a standing part that rises obliquely upward on the indoor side as an integral hollow body, and the width of the girder part, the horizontal part, and the standing part Is set to the same width as the opening width of the building window. A plurality of ventilation ducts in the building can be connected to the upright portion, and a ventilation louver is formed on the lower surface of the gavel portion.
JP-A-10-72921

  When using such a conventional technique, the horizontal part penetrating the wall of the building and the standing part standing on the indoor side are both formed to have the same width as the gavel part on the outdoor side, and therefore should be opened to the wall of the building. In addition to an excessively large opening for mounting, the overall weight tends to be large, and there is a problem that installation work is extremely complicated.

  Therefore, in view of the problems of the prior art, the object of the present invention is to minimize the mounting opening and reduce the installation work by combining a ventilation duct and elbow with an outdoor housing. It is to provide a building ventilation unit that can be simplified.

  In order to achieve such an object, the structure of the present invention includes a ventilation duct penetrating the wall of the building in and out, an elbow connected to the outside end of the duct, and an elbow that is housed and protrudes to the outside. The main body of the main body is to open the lower end of the elbow to the lower surface.

  The casing can be filled with a heat insulating material.

  In addition, a grill adapted to the tip of the elbow may be attached to the lower surface of the housing, a register may be attached to the indoor side end of the duct, and a ventilation fan may be installed in the duct.

  In such a configuration, the duct penetrating the wall of the building and the elbow connected to the outdoor side end of the duct form an air passage communicating with the inside and outside of the building and can exhibit an indoor ventilation function. it can. On the other hand, the outdoor housing houses the elbow and conceals the elbow, so that the appearance of the building can be put together in an orderly manner. However, the frame may be used as a shade for a sun shade attached to an opening such as a window or an entrance of a building. It may be installed as a dummy where there is no part. In other words, the width dimension of the housing only needs to be larger than the width of the duct or elbow, and can be arbitrarily set in consideration of the appearance of the entire building. Moreover, it is only necessary to provide an opening for mounting the duct on the wall, and the casing may be assembled so that, for example, an elbow is incorporated and made separate from the duct, and the duct and elbow are connected at the time of installation. Therefore, the entire installation work is easy.

  The heat-insulating material filled in the housing can simultaneously block solar heat when the solar radiation is blocked by the housing. The heat insulating material is preferably a lightweight material having a high heat insulating effect. For example, a block-like or granular foamed polystyrene material, a rock wool material, a glass wool material, or the like is preferable.

  By attaching a grill that fits the tip of the elbow to the lower surface of the housing, it is possible to prevent entry of small animals such as birds and mice, and wind and rain. In addition, a register attached to the indoor side end of the duct can adjust the ventilation amount as necessary. However, the register here refers to a grill having a ventilation amount adjusting means such as a shutter or a damper.

  The ventilation fan built in the duct can perform indoor forced ventilation by operating it. The ventilation fan may be either for exhaust or for intake, and may be a type that can switch between the two.

  Hereinafter, embodiments of the invention will be described with reference to the drawings.

  The ventilation unit of a building includes a duct 11 for ventilation, an elbow 12, and a housing 20 on the outdoor side (FIGS. 1 and 2).

  The ventilation unit of the building is attached to the wall W of the building. The wall W is configured by adding an indoor wall member W2 on the indoor side and an external wall member W3 on the outdoor side to a wall main body W1 including a building structural material (not shown).

  The duct 11 penetrates through the wall body W1 and the inner wall material W2 of the wall W, and substantially penetrates the wall W inward and outward. The duct 11 is formed in a rectangular shape having a rectangular cross section by a single material or a composite material having good heat insulation. The indoor side end of the duct 11 slightly protrudes from the inner wall material W2, and a resistor 13 is attached. The outdoor side end of the duct 11 opens to the outdoor side of the wall body W1.

  The elbow 12 is incorporated in the housing 20 and is connected to the outdoor side end of the duct 11 via a mounting plate 21 of the housing 20. The downward tip of the elbow 12 opens to the lower surface of the housing 20, and a grill 14 that fits the tip of the elbow 12 is attached to the lower surface of the housing 20. The mounting plate 21 is formed with an opening 21a that matches the cross-sectional shape of the elbow 12, and the elbow 12 is housed in the housing 20 with the horizontal base aligned with the opening 21a. However, the vertical and horizontal dimensions of the opening 21 a are not larger than the outer dimension of the duct 11 and are not smaller than the inner dimension of the duct 11.

  The casing 20 is formed by attaching a single-flow type flange 22 to the mounting plate 21 with the opening 21a. The eaves 22 are configured by, for example, filling an outer shell made of sheet metal with a heat insulating material 23, and on the lower surface of the eaves 22, there are step portions 22 a for draining along three sides excluding the mounting plate 21 side. It is formed continuously (FIG. 3).

  The housing 20 is fixed to the outdoor side of the wall body W1 through the mounting plate 21 so as to protrude to the outdoor side of the building (FIG. 1). The duct 11 is fixed to the mounting opening Wa formed in the wall W prior to fixing the housing 20. The outer wall material W3 in the vicinity of the housing 20 is mounted so as to cover the mounting plate 21 after the housing 20 is fixed. At this time, by aligning the opening 21a of the mounting plate 21 with the outdoor side end of the duct 11 (FIG. 2), the duct 11 and the elbow 12 in the housing 20 are communicated with each other through the opening 21a. Therefore, the duct 11 and the elbow 12 form an air passage that communicates with the inside and outside of the building, and can ventilate indoors. Moreover, since the register 13 at the indoor side end of the duct 11 is exposed on the indoor side of the building (FIG. 4), the amount of ventilation can be adjusted by operating the adjustment knob 13a attached to the register 13.

  In the above description, the duct 11 can be equipped with the ventilation fan F (FIGS. 1 to 3). The ventilation fan F can forcibly ventilate the indoor space by exhausting indoor air or sucking outdoor air. The ventilation fan F is activated and stopped by an indoor switch, and is preferably automatically stopped by fully closing the indoor register 13. In addition, the ventilation fan F is a type which can be used for both intake and exhaust, and can select a rotation direction to be normal or reverse.

  Further, the lower part of the duct 11 and the housing 20 may be an opening of a building such as a window or an entrance, instead of the wall W of the building as shown in FIG. 1 is used as a mere dummy, it may be used as a sunshade for an opening of a building. In addition, it is preferable to match | combine the left-right width dimension of the housing 20 at this time with the opening width of the opening part of a building.

  Generally, the opening 21a of the mounting plate 21 may be formed at the center in the left-right width direction of the housing 20, that is, at the center of the mounting plate 21, but is shifted to the left or right of the mounting plate 21 as necessary. It may be. For example, when installing in the upper part of the opening part of a building, the register | resistor 13 on the indoor side can be arranged to be shifted to the left or right of the opening part. It should be noted that the elbow 12 in the housing 20 is always arranged in alignment with the opening 21a.
