Description

  The present invention relates to a house ventilation device for ventilating a room by natural ventilation and an opening frame provided with a ventilation vent.

  Conventionally, as a natural ventilation system for a house that does not require running energy, wind ventilation is used to ventilate the room using wind power by providing vents for natural ventilation on two walls in different rooms, and one wall of the room There is known a temperature difference ventilation in which ventilation holes for natural ventilation are provided at the upper position and the lower position, and the room is ventilated using the temperature difference between the inside and outside.

  When performing natural ventilation by temperature difference ventilation, it is necessary to provide ventilation vents at the upper and lower positions of one wall surface, but usually a large opening frame is provided on the wall surface for purposes such as lighting. For this reason, when the opening frame and the ventilation vent are provided together, the following various problems have occurred.

  For example, if an opening frame with an open / close-type window shoji that allows people to go in and out is provided on the wall surface, if you try to provide a lower ventilation vent under the window shoji, The straddle step at the time of entering / exiting the opening part frame is increased by the height of the lower vent, and it is particularly difficult to make a sweep-out type with no straddle step.

  In addition, it is conceivable to provide a side-sliding window or an awning window above the window shoji as the upper ventilation vent, but these are both expensive and incur high costs. Since the height of the window shoji is limited to a low level, the entrance / exit height of the person cannot be sufficiently secured, and the usability may be deteriorated.

  Furthermore, when an awning window or the like is used as a ventilation vent, the window must be closed when going out or sleeping to prevent rain from falling and security measures, and cannot be always opened.

  On the other hand, Patent Document 1 and Patent Document 2 describe a configuration in which upper and lower vents for natural ventilation are provided at the upper end and the lower end of an openable window shoji, respectively. In this way, by providing the upper and lower vents integrally with the window shoji, it is possible to provide natural ventilation using temperature difference ventilation as described above, but to provide a sweep-out type opening frame without straddle steps In addition to making it possible, it is possible to secure a sufficient height for people to enter and exit. Moreover, each ventilator is provided with an open / close type louver mechanism, and each ventilator can always be opened.

  However, as disclosed in Patent Document 1 and Patent Document 2, if the vents equipped with the louver are provided at the upper and lower ends of the window screen, the lighting area of the entire window screen is reduced accordingly. In particular, there is a drawback that the lighting that should originally be obtained is blocked by the upper louver. In addition, when the opening / closing type louver mechanism is provided at both upper and lower ends of the window screen, the weight of the entire window screen increases, so that the operability during opening / closing deteriorates.

  Therefore, the present invention eliminates the above problems and realizes natural ventilation by the upper and lower vents on one wall surface, and can cope with a sweeping window by preventing the straddle step under the window shovel from becoming high. In addition, an object is to secure a sufficient lighting area so as not to hinder the operability of the window shoji.

  In order to solve the above-described problems, a residential ventilation apparatus according to the present invention includes a first ventilating vent that is openable and closable formed in a heel portion above a window screen, and an open / close that is also formed at the lower end of the window screen. Natural ventilation can be obtained by a free second ventilation vent.

  In the above, the ridge part in which the said 1st vent was formed is a part of the upper ridge of the window frame surrounding the said window shoji.

  Further, the opening frame provided with the ventilation vent in the present invention is a first ventilating vent that can be opened and closed formed in a portion of the upper ridge of the window frame surrounding the window shoji above the window shoji. And a second ventilating opening that can be freely opened and closed formed at the lower end of the window shoji.

  A plurality of the above-mentioned window screens are provided so as to be mutually different. The ventilation vents can be opened and closed by louvers or dampers each having one or more movable blades. Further, the ventilation vents are provided over substantially the entire width of the window frame.

  The movable blade plate provided in the first ventilation port has translucency. Further, the movable blade plate provided in the first vent has a double glass or other heat insulating structure.

  The second ventilation port is a ventilation path bent in a substantially Z shape so that the indoor side is higher than the outdoor side when the damper provided in the ventilation port is opened. Further, the movable blade plate provided in the second vent is a fireproof heat insulating plate.

  In this invention, the first vent is provided in the heel portion above the window shoji, and the second vent is provided at the lower end of the window shoji, thereby realizing natural ventilation by the upper and lower vents on one wall surface, It is possible to cope with the sweep-out window by preventing the step difference below the window screen from becoming high, and it is easier to secure the lighting area than the case where the first vent is provided at the upper end of the window screen. Yes.

  Further, since the window shoji is provided with a vent at only its lower end, the number of members for opening and closing the vent is smaller than in the case where vents are provided at both upper and lower ends as in the prior art. Thus, the weight of the window screen can be reduced as much as necessary, and the opening / closing operability of the window screen can be improved.

  Furthermore, since the first vent is provided in the upper ridge of the opening frame surrounding the window shoji, compared to the case where the first vent is formed by providing an awning window or the like above the window shoji, Since the first vent is provided, the height of the window screen is not limited to a low level, and it is easy to ensure the height of the person entering and exiting the opening frame.

  Furthermore, since the ventilation vents are provided over substantially the entire width of the left and right of the opening frame, a sufficient effective opening area can be obtained even if the height is set low. In addition, by setting the height of the vent so low, it is possible to always open while restricting the intrusion of people.

  Moreover, since the movable blade provided in the first vent has translucency, the lighting from the first vent is not blocked by the movable vane, and the light collection area is increased accordingly. It can be secured sufficiently.

  Furthermore, since the movable blade provided in the first vent has a double-glass or other heat insulating structure, the first vent is closed with the vane to improve the indoor thermal environment. Can be maintained.

  Further, since the second vent is a vent path bent in a substantially Z shape so that the indoor side is higher than the outdoor side in a state where the damper is opened, it can block the line of sight from the outside, If it is a normal wind, it is possible to prevent the entry of rain almost completely, and since the unauthorized unlocking tool is difficult to enter, it is excellent in crime prevention.

  Furthermore, since the movable vane plate provided in the second vent is made of a fireproof and heat insulating plate, the second vent is closed with the vane to improve the indoor thermal environment and to prevent fire. Measures can be realized.
