JP 2007-170138 A

  Here, in the ventilation structure described in Patent Document 1, the ventilation efficiency is improved by promoting the inflow of outside air into the room by projecting the window panel to the outdoor side. However, as shown in this configuration, it is possible to improve the ventilation efficiency at the center of the room, for example, by simply increasing the inflow of outside air, but at the corners and corners along the wall of the room, for example. There is concern about poor ventilation. In other words, even if a partial improvement in ventilation efficiency can be expected, the benefit of the improvement in ventilation efficiency is expected to be small when viewed in the entire room.

  This invention is made | formed in view of the said situation etc., and aims at provision of the ventilation apparatus of the building which can improve indoor ventilation efficiency suitably.

  Hereinafter, effective means for solving the above-described problems will be described while showing effects and the like as necessary. In the following, for easy understanding, the corresponding configuration in the embodiment of the invention is appropriately shown in parentheses, but is not limited to the specific configuration shown in parentheses.

Means 1. Two window openings (window openings 41 and 42) provided on the outer wall portion (first outer wall portion 31) that is one surface of the building and spaced apart from each other at least in the width direction of the outer wall portion;
Each of these window openings is provided with a window opening / closing panel (window panels 51, 52, etc.) for opening and closing the window opening,
As the window opening / closing panel, a first window panel (window panels 51, 52) that is rotatable in a range including both a closed position that closes the window opening and an open position that protrudes from the window opening to the outdoor side and opens the window opening. )
The first window panels are configured such that an end that is closer to each other in the width direction is a rotation base end, and an end that is far from each other in the width direction is a rotation tip. ,
The outer wall part includes a first wall part (partition wall part 34 or third outer wall part 33) that faces the outer wall part from both sides in the width direction of the outer wall part, and the outer wall part across the first wall part. The interior space is partitioned with each wall portion of the second wall portion (second outer wall portion 32) facing each other,
Rectifying means (window panels 51, 52, inner window panel 101, rectifying so that the wind that flows in from one of the window openings to the windward side and flows toward the other of the window openings flows along the first wall portion. 102 or curtain 56).

  According to the means 1, when the wind blows along the outer wall portion (specifically, the outer wall surface) outdoors, the indoor ventilation can be performed by opening both the window openings, for example. Specifically, the first window panel on the windward side of the first window panels provided at each window opening to such an extent that outside air (outdoor air) can be guided indoors through the window opening on the windward side. The first window panel on the leeward side is rotated so that indoor air can be discharged through the window opening on the leeward side. In such a state, outside air is guided into the room by the first window panel associated with the window opening on the windward side. Also, negative pressure is generated in the vicinity of the window opening on the leeward side, so that the indoor air is expelled to the outdoors. Thereby, ventilation of the room where the window structure shown in this means was adopted can be performed.

  Further, in this means, in particular, rectification is performed so that the wind that flows from the windward window opening and flows toward the leeward window opening flows along the first wall portion. Thus, by causing the flow of the wind along the first wall portion, the replacement of the air near the first wall portion can be promoted, and the ventilation efficiency in the entire room can be suitably improved.

  Mean 2. The rectifying means is at least at the same height as the window opening in the indoor space, and a rectifying surface (curtain) provided at an end portion close to each other in the window opening or a position between the end portions. 56, which faces the walls 33 and 34), and adjusts the wind direction in the indoor space of the wind flowing in from the windward side by the rectifying surface. Ventilation device.

  According to the means 2, the flow of the wind flowing into the room through the window opening on the windward side is adjusted by the rectifying surface. Thereby, the flow of the wind along the 1st wall part shown to the means 1 is suitably realizable.

  For example, the rectifying function can be suitably exhibited by setting the rectifying surface to be opposed to the first wall portion and extending from the outer wall portion to the second wall portion side.

Means 3. The window opening and closing panel includes a second window panel (inner window panels 101 and 102) disposed so as to face the first window panel from the indoor side,
The second window panel is pivotable indoors with the end on the same side as the pivot base end of the first window panel as the base end.
Further, the second window panel constitutes the rectification means, and rectifies the wind in the indoor space in a state where the second window panel is rotated indoors. Ventilation equipment for buildings as described in.

  According to the means 3, the window opening is opened by rotating the first window panel to the outdoor side and rotating the second window panel to the indoor side. Here, for example, by causing the second window panel to face the window opening obliquely or to be orthogonal to the outer wall portion, the flow of the wind in the indoor space is closest to the second window panel. It can be rectified along the wall.

  Means 4. The building ventilation device according to claim 3, further comprising an interlocking mechanism for rotating the first window panel to the outdoor side in conjunction with the rotation of the second window panel to the indoor side.

  According to the means 4, when ventilation is performed, the indoor window panel (second window panel) is rotated so that the outdoor window panel (first window panel) moves to the outdoor side. It will turn. For this reason, when performing ventilation, the user turns the second window panel to the indoor side, the first window panel turns to the outdoor side, the window opening is opened, and the second window panel is turned. There is no need to rotate the first window panel after the operation. Therefore, the internal and external window panels can be used in combination to improve ventilation efficiency, and the complication of the ventilation preparation work caused by the improvement can be suppressed.

  Means 5. The first window panel is rotatable between an open position on the outdoor side and an open position on the indoor side with respect to the window opening, and is rotated indoors at the same rotation angle as the second window panel. The building ventilator according to the means 3 or 4, characterized by being movable.

  When the windward first window panel protrudes to the outdoor side, negative pressure is generated on the outer surface side of the first window panel (more specifically, near the rotating tip of the first window panel), and the windward first window The outdoor wind that has passed through the panel is drawn toward the outer wall side. When the outdoor wind drawn in this way flows into the window opening on the leeward side, the discharge of air through the window opening on the leeward side is hindered, and the ventilation efficiency may be reduced. In this regard, by rotating the leeward window panel to the outdoor side, it is possible to prevent such wind inflow and avoid a decrease in ventilation efficiency.

  Here, in the vicinity of the window opening on the leeward side, the outdoor wind crosses the window opening, so that negative pressure is generated in the vicinity of the window opening and the indoor air is sucked out, and ventilation efficiency can be improved by the sucking. For this reason, for example, when the outdoor wind that bypasses the windward window panel is drawn to the downstream position beyond the window opening on the leeward side, it is not necessary to project the first window panel on the leeward side. By projecting to the outdoor side, it is assumed that the first window panel becomes a resistance and the wind speed of the outdoor wind near the window opening on the leeward side decreases. This can weaken indoor air suction through the window opening on the leeward side and hinder the improvement of ventilation efficiency. In this means, paying attention to this point, the first window panel can be turned indoors. Thereby, the ventilation mode can be changed so that ventilation can be efficiently performed according to the wind speed or the like of the outdoor wind.

  In addition, about the 1st window panel, it replaces with the said 2nd window panel by enabling it to turn to an indoor side in the state which overlapped with the 2nd window panel (for example, with the same rotation angle as a 2nd window panel). The window panel can be given a rectifying function for indoor wind. In the case of adopting such a configuration, for example, the rotation base end portion of the first window panel may be biased to the nearest one side of the first wall portions relative to the rotation base end portion of the second window panel. .

Means 6. The first window panel is rotatable between an open position on the outdoor side and an open position on the indoor side with respect to the window opening,

  According to the means 6, the first window panel on the leeward side is turned to the indoor side so as to be opposed to the window opening obliquely or orthogonal to the outer wall part (that is, opposed to the first wall part). By doing so, it can rectify | straighten so that the wind in indoor space may move along the 1st wall part near the said window opening.

Means 7. The rectifying means has a curtain member (curtain 56) provided at the same height as the window opening and facing the first wall portions.
The curtain member has an end on the outer wall side facing the intermediate wall including the ends of the two window openings between the two window openings, and an end on the second wall side is the second. The building ventilator according to any one of means 1 to means 6, wherein the building ventilator is disposed so as to be separated from the wall.

  According to the means 7, the outside air flowing into the room from the window opening on the windward side moves along the first wall portion on the windward side → the second wall portion → the first wall portion on the opposite side. Thereby, the air which exists in the position along a wall part can be moved suitably.

  In addition, it is possible to guide the outside air to the back side (the second wall side) in the indoor space, and it is possible to preferably avoid the inconvenience that the outside air flowing into the room from one window opening immediately flows out from the adjacent window opening. it can. Therefore, it becomes possible to suitably improve the ventilation efficiency in the entire indoor space.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. This embodiment is embodied in a ventilation device provided in a bathroom of a building. 1A is a transverse cross-sectional view showing the bathroom 21 of the building 10, and FIG. 1B is a vertical cross-sectional view (cross-sectional view taken along line AA in FIG. 1) showing the bathroom 21.

  As shown in FIG. 1A, a building 10 includes a first outer wall portion 31 facing an adjacent building 11 and a second outer wall portion facing the first outer wall portion 31 from the side opposite to the building 11. 32 and a third outer wall portion 33 provided so as to straddle the first outer wall portion 31 and the second outer wall portion 32, and the interior and the exterior are partitioned by these outer wall portions 31 to 33. A partition wall portion 34 that partitions the bathroom 21 and the dressing room 22 is provided between the first outer wall portion 31 and the second outer wall portion 32, and the bathroom space BS is partitioned by these wall portions 31 to 34. Has been.

  The distance dimension L1 between the first outer wall part 31 and the second outer wall part 32 is set to be larger than the distance dimension L2 between the third outer wall part 33 and the partition wall part 34, and the bathroom 21 has a horizontally long shape as a whole. ing. In the bathroom 21, a bathtub is disposed so as to follow the first outer wall portion 31, and a portion closer to the second outer wall portion 32 than the bathtub is a washing place.

  An entrance / exit 38 (door 39) that connects the bathroom 21 and the dressing room 22 is provided in a part of the partition wall 34 that faces the washing area. The entrance / exit 38 is provided with a door sensor for detecting the opening / closing position of the door 39 and a door drive unit for driving the door 39 (not shown). The door drive unit is electrically connected to a control device for automatic ventilation, which will be described later, and the door 39 is opened and closed based on a drive signal output from the control device. Thereby, the door 39 can be opened / closed not only manually but also electrically controlled. Moreover, although the ventilation fan (not shown) is attached to the ceiling part 36 of the bathroom 21, it is also possible to abbreviate | omit about this ventilation fan.

  A portion of the first outer wall portion 31 that is above the bathtub (specifically, the portion of the floor portion 35 and the ceiling portion 36 that is closer to the latter) (see FIG. 1B) has a substantially rectangular shape that penetrates indoors and outdoors. Window openings 41 and 42 are formed. The window openings 41 and 42 are provided apart from each other in the width direction of the first outer wall portion 31, and window sashes are provided so as to correspond to the window openings 41 and 42 on a one-to-one basis. The window sash includes a sash frame (not shown) as an object to be attached to the first outer wall portion 31 and substantially rectangular window panels 51 and 52 (specifically, glass panels).

  The window panels 51 and 52 are single-opening type window panels, and are rotatable within a predetermined range including both a closed position that closes the window openings 41 and 42 and an open position that opens the window openings 41 and 42. It is attached to the window sash. More specifically, the window panels 51 and 52 are attached such that the end portions close to each other are the rotation base end portions, and the opposite end portions are the rotation tip end portions. Rotation in the range of 90 degrees outward (state orthogonal to the first outer wall 31) to 90 degrees indoor (state orthogonal to the first outer wall 31) is allowed.

  The first outer wall portion 31 is provided with a window panel drive section for individually driving the window panels 51 and 52. These drive sections are electrically connected to a control device for automatic ventilation described later. It is connected to the. And the window panels 51 and 52 are opened and closed based on the drive signal output from the control apparatus. Thus, the window panels 51 and 52 can be opened / closed not only manually but also electrically controlled.

  Since the thickness dimension of the first outer wall portion 31 is set to be larger than the thickness dimension of the window panels 51 and 52, when the window panels 51 and 52 are disposed at the closed position, the window opening is set. 41 and 42 are accommodated. More specifically, the window panels 51 and 52 are at the outermost positions in the window openings 41 and 42 in a state where the window panels 51 and 52 are disposed at the closed positions. When the window panels 51 and 52 are rotated to the outdoor side when the window openings 41 and 42 are opened, almost the entire window panels 51 and 52 protrude from the window openings 41 and 42.

  Further, the width dimension of the window panels 51 and 52 is set to be larger than the length dimension of the window openings 41 and 42 in the thickness direction of the first outer wall portion 31. For this reason, when the window panels 51 and 52 are rotated indoors when the window openings 41 and 42 are opened, most of the window panels 51 and 52 including the rotating front end portion are opened from the window openings 41 and 42. It will protrude.

  As shown in FIG. 1A, in the space between the adjacent building 11 and the main building 10, the wind is not in the direction intersecting the first outer wall portion 31 but in the direction along the first outer wall portion 31. Easy to flow. In the present embodiment, when wind is blowing along the first outer wall portion 31 (specifically, in the width direction of the first outer wall portion 31), ventilation efficiency is obtained by ventilating the bathroom 21 using the wind. One of the characteristics is that the improvement is achieved.

  Here, with reference to FIG.1 and FIG.2, the mode of ventilation in the bathroom 21 using the window openings 41 and 42 and the window panels 51 and 52 is demonstrated. FIG. 2 is a schematic diagram showing the state of ventilation, and the flow of air outdoors and the movement of air indoors are indicated by large and small arrows. In the following description, the case where the wind direction of the outdoor wind is directed from the partition wall 34 side to the third outer wall 33 side will be exemplified, and the windward window opening 41 and the window panel 51 are referred to as “windward window opening 41” and The “leeward window panel 51”, the leeward window opening 42 and the window panel 52 are referred to as “leeward window opening 42” and “leeward window panel 52”.

  About ventilation of the bathroom 21, since the effective ventilation aspect changes with the speed (wind speed) of the wind which flows along the 1st outer wall part 31, in the following description, the case where a wind speed is comparatively low is demonstrated first, and wind speed after that The case where is relatively high will be described.

  As shown in FIG. 2A, when the outdoor wind direction is from the windward side window opening 41 side to the leeward side window opening 42 side, the door 39 is in a closed state and the both-panel panel 51 is closed. , 52 is rotated outdoors to open the window openings 41, 42. In the windward window opening 41 located on the windward side, the window panel 51 is opened, so that inflow of outside air through the windward window opening 41 is allowed. Specifically, a part of the wind flowing along the first outer wall portion 31 is guided by the windward side window panel 51 protruding from the first outer wall portion 31 (windward side window opening 41) and is on the windward side window opening 41 side. The direction is changed and the air flows into the bathroom 21 (bathroom space BS) through the windward window opening 41.

  Thus, when the windward side window panel 51 protrudes outdoors and is used as a foothold for introducing outside air, it is negative in the vicinity of the outer surface of the windward side window panel 51 (more specifically, the region immediately downstream of the rotating tip). A pressure region is created. For this reason, a part of the wind that has passed outside the windward window panel 51 (windward window opening 41) is drawn toward the first outer wall 31 side. Here, when the leeward side window opening 42 is opened, the leeward side window panel 52 is rotated to the outdoor side (projected), so that the wind drawn toward the first outer wall 31 side as described above becomes leeward. Colliding with the side window panel 52, the inflow of the wind into the upwind window opening 41 is avoided. The outside air that has flowed into the bathroom through the windward window opening 41 moves toward the second outer wall 32 along the partition wall 34.

  In the outside air that moves toward the second outer wall portion 32 along the partition wall portion 34, the momentum when flowing into the bathroom 21 becomes weaker as it approaches the second outer wall portion 32. However, by reaching the second outer wall portion 32 and moving toward the third outer wall portion 33, the negative pressure generated in the vicinity of the leeward window opening 42 is attracted to the leeward window opening 42 side, and the momentum is attenuated. Thus, it is avoided that itching occurs.

  The air that has moved through the bathroom 21 in this manner is discharged to the outside through the leeward window opening 42. In particular, by suppressing the inflow of outside air into the leeward window opening 42 by the leeward window panel 52, the discharge of the air in the bathroom 21 through the leeward window opening 42 is ensured. That is, the windward side window opening 41 functions as an intake port, and the leeward side window opening 42 functions as a discharge port, and the outside air is prevented from flowing from the discharge port side and flowing to the intake port side. Thereby, a ventilation function will be exhibited suitably.

  Next, with reference to FIG.2 (b), the ventilation aspect in case a wind speed is comparatively large is demonstrated. In this embodiment, the case where the wind speed is relatively low means that the wind that bypasses the windward side window panel 51 on the outdoor side as described above from the leeward side window opening 42 or the leeward side window opening 42 in the first outer wall 31. The case where the wind speed is relatively high indicates that the wind that bypasses the windward window panel 51 on the outdoor side is leeward than the leeward window opening 42 on the first outer wall portion 31. The case where it is drawn to the part to become is shown.

  When the wind speed is relatively high, the wind that bypasses the windward side window panel 51 does not jump into the leeward side window opening 42, so that the leeward side window panel 52 protrudes to the outdoor side to restrict the flow of the wind. do not have to. Therefore, by rotating the leeward side window panel 52 to the indoor side, the wind resistance near the leeward side window opening 42 is reduced, and the wind speed on the outdoor side (the flow velocity of the wind along the first outer wall portion 31) is reduced. Reduce the decline. As a result, the negative pressure generated in the vicinity of the leeward window opening 42 is increased, and the suction of air in the leeward window opening 42 is increased. Therefore, improvement in ventilation efficiency can be expected.

  Further, by projecting the leeward window opening 42 on the indoor side, the negative pressure generated near the leeward window opening 42 is easily affected by the air existing along the third outer wall portion 33, The movement of air along the third outer wall portion 33 is promoted. That is, at least at a position close to the leeward window opening 42, the air toward the leeward window opening 42 is rectified so as to move along the third outer wall portion 33.

  In this Embodiment, the device for generating the movement (wind flow) of the air along the inner wall of the bathroom 21 more reliably and effectively is given. Hereinafter, with reference to FIG.1 and FIG.2, the structure concerning the device is demonstrated.

  A rail member 55 is disposed at a position adjacent to the ceiling portion 36 in the bathroom 21 shown in FIG. The rail member 55 straddles the second outer wall portion 32 and the intermediate portion between the window openings 41 and 42 in the first outer wall portion 31, and the curtain 56 can be attached to the rail member 55. .

  In a state where one end of the curtain 56 is fixed to the end portion of the rail member 55 on the first outer wall portion 31 side, the curtain 56 is expanded to the second outer wall portion 32 side, whereby the arrangement of the curtain 56 at the ventilation-compatible position is completed. (See FIG. 1 (b)).

  The width W of the curtain 56 is set to be smaller than the distance L1 between the outer wall portions 31 and 32 (see FIG. 1A). For this reason, in the state where the curtain 56 is disposed at the ventilation-compatible position, a separation portion is formed between the curtain 56 and the second outer wall portion 32.

  More specifically, the bathroom space BS is roughly divided into a region on the windward side window opening 41 side and a region on the leeward side window opening 42 side by the curtain 56, and passes through the separated portion by the walls 32 to 34 and the curtain 56. A passage (passage path) for air (wind) is formed. In this way, by forming an air passage, the outside air guided into the bathroom 21 is rectified so as to move along the wall portions 31 to 34.

  When the bathroom 21 is ventilated, the outside air flowing in from the windward side window opening 41 is immediately directed to the leeward side window opening 42 when the inflow speed of the outside air is small and the discharge speed of the air in the bathroom 21 is large. There is a possibility that the shortcut shown in the alternate long and short dash line of FIG. When such an event occurs, there is a concern that ventilation in the bathroom 21 as a whole, particularly the portion on the side of the second outer wall 32 in each of the wall portions 33 and 34 and in the vicinity of the second outer wall 32 will not be performed well. The

  In this regard, if the curtain 56 is arranged at the ventilation-compatible position, the passage of outside air is restricted so as to pass through the separated portion, so that it is possible to avoid the outside air from reaching the second outer wall portion 32. Therefore, generation | occurrence | production of the said inconvenience can be suppressed and the ventilation efficiency in the whole bathroom 21 (especially part along an inner wall) can be improved suitably.

  In addition, when performing natural ventilation mentioned above by opening the window openings 41 and 42, it is preferable to block the air flow between the bathroom 21 and the dressing room 22 by closing the door 39. Thereby, it can suppress that the relationship between both window openings 41 and 42 falls and air does not move well from one window opening to the other window opening.

  As described above in detail, in this embodiment, a ventilation structure is constructed using the window openings 41 and 42, the window panels 51 and 52, the curtain 56, and the like. According to this ventilation structure, the following effects can be expected.

  When the wind is blowing along the first outer wall portion 31, for example, the interior of the bathroom 21 can be ventilated by moving the window panels 51 and 52 to the open position. Specifically, the windward window panel is rotated to the outdoor side to open the windward window opening, and the leeward window panel is rotated to the outdoor side or indoor side to open the leeward window opening. Open. If both the window openings are opened in this way, the outside air is guided into the bathroom 21 by the window panel on the leeward side, and the air in the bathroom 21 is discharged to the outside due to negative pressure in the vicinity of the window opening on the leeward side. As a result, an air flow can be generated in the bathroom 21 from one window opening (inlet or inlet) to the other window opening (outlet or outlet).

  In particular, by arranging the curtain 56 in the bathroom 21 and restricting the passage of air, the air in the bathroom 21 is rectified so as to move along the wall portions 31 to 34. Thereby, the movement of the air staying along the walls 32 to 34 is promoted, and for example, the entire room (including the side of the wall) in which the window structure shown in this means is adopted can be efficiently ventilated. In particular, the efficiency of removing water droplets attached to the inner wall can be improved by positively ventilating the wall.

  By promoting the drying of the bathroom 21 in this way, the time required for drying, that is, the time during which the window openings 41 and 42 are kept open can be shortened. Thereby, the fall of crime prevention can also be suppressed.

  Further, by rotating the leeward window panel indoors to open the leeward window opening, the window panel faces the nearest wall (the third outer wall 33 or the partition wall 34). Become. As a result, at least room air is rectified along the wall on the leeward side, and ventilation efficiency at the wall can be improved.

  Further, according to the ventilation structure shown in the present embodiment, when the wind is blowing from the windward side window opening 41 side to the leeward side window opening 42 side, the wind is blown from the leeward side window opening 42 side to the windward side window opening 41 side. The ventilation function can be suitably exhibited in both cases where the air is blowing.

  Since ventilation can be executed only by opening each of the window panels 51 and 52, it is possible to suppress complication of preparation work due to improvement of ventilation efficiency.

  Further, in the present embodiment, a ventilation device (ventilation system) 60 is constructed by combining the above-described ventilation structure with an electrical configuration for controlling ventilation, thereby improving convenience and further improving ventilation efficiency. Improvements are being made. Hereinafter, the electrical configuration of the ventilation device 60 will be described with reference to the block diagram of FIG.

  The ventilation device 60 includes a control device 70 that executes control related to automatic ventilation. The control device 70 is provided with an MPU for performing various calculations and an input / output port.

  On the input side of the control device 70, a wind speed sensor 81 for detecting the wind speed and direction of the outdoor wind flowing along the first outer wall portion 31, a human sensor 82 for detecting whether or not there is a person in the bathroom 21, A humidity sensor 83 that detects humidity in the bathroom 21, a door sensor 84 that detects the position of the door 39, and an automatic ventilation switch 85 that switches on / off of automatic ventilation are connected. In the control device 70, various controls relating to automatic ventilation are executed based on information input from these various configurations 81 to 85.

  The wind speed sensor 81 is provided at a position adjacent to the window openings 41 and 42 on the outer wall surface of the first outer wall portion 31, and the human sensor 82 and the humidity sensor 83 are provided in the bathroom 21. The door sensor 84 and the automatic ventilation switch 85 are provided in the dressing room 22, but the detailed arrangement of these various configurations 81 to 85 is arbitrary.

  On the output side of the control device 70, a first window panel drive unit 91 for driving the windward side window panel 51, a second window panel drive unit 92 for driving the leeward side window panel 52, and the door 39 are driven. A door drive unit 93 and a ventilation fan 94 are connected.

  When the drive signal is output from the control device 70 to the various configurations 91 to 94, the window panels 51 and 52, the door 39, and the ventilation fan 94 are operated.

  Next, with reference to the flowchart of FIG. 4, the ventilation control process performed regularly (for example, every 1 second) in the control apparatus 70 is demonstrated.

  In the ventilation control process, first, in step S101, it is determined whether or not the automatic ventilation switch 85 is turned on. If a negative determination is made in step S101, the ventilation control process is terminated as it is.

  On the other hand, if an affirmative determination is made in step S101, the process proceeds to step S102 to determine whether or not automatic ventilation is being executed. If a negative determination is made in step S102, the process proceeds to step S103.

  In step S103, it is determined whether the bathroom is in use. Specifically, based on a detection signal (detection information) from the human sensor 82, it is determined whether or not there is a person in the bathroom 21. If an affirmative determination is made in step S103, the ventilation control process is terminated as it is. On the other hand, when a negative determination is made in step S103, that is, when it is determined that the bathroom 21 is not in use (when it is determined that there is no person in the bathroom 21), the process proceeds to step S104.

  In step S104, based on a detection signal (detection information) from the humidity sensor 83, it is determined whether or not the humidity of the bathroom 21 is equal to or higher than a preset value (specified value). When a negative determination is made in step S104, that is, when it is determined that the bathroom 21 is not wet, the ventilation control process is terminated as it is. On the other hand, if an affirmative determination is made in step S104, that is, if it is determined that the bathroom 21 is moist, ventilation execution processing in step S105 and subsequent steps is performed. That is, in the present embodiment, automatic ventilation is executed when all the conditions that the automatic ventilation switch is on, the bathroom is not in use, and the humidity is equal to or higher than a specified value are satisfied. In the automatic ventilation execution process, a different ventilation mode is selected according to the wind speed of the wind flowing along the first outer wall portion 31.

  In the ventilation execution process, first, in step S105, it is determined whether or not the velocity of the wind flowing along the first outer wall portion 31 is equal to or higher than a preset value (specified value). If an affirmative determination is made in step S105, that is, if it is determined that the wind speed is sufficient for ventilation using the window openings 41 and 42, the process proceeds to step S106.

  In step S106, a first automatic ventilation start process for performing ventilation using the window openings 41 and 42 is executed. In the first automatic ventilation start process, it is first determined whether or not the door 39 is opened based on the detection information from the door sensor 84. If the door 39 is opened, the door drive unit 93 is contacted. The drive signal is output to close the door 39.

  In addition, the control device 70 stores in advance rotation position information of each of the window panels 51 and 52 that can efficiently perform ventilation for each wind direction and wind speed, and rotation position information corresponding to the current wind direction and wind speed. Then, a drive signal is output to each window panel drive unit 91, 92 in accordance with the rotation position information. Specifically, for example, as shown in FIG. 2, when the wind speed of the outdoor wind is smaller than a preset value, the rotational position of the window panel on the leeward side is set to be on the outdoor side, When it is larger than the same value, the rotational position of the window panel on the leeward side is set to be on the indoor side. Thereby, the ventilation mode on the side with higher ventilation efficiency is selected according to the wind speed of the outdoor wind.

  The rotational position (rotational angle) of the windward window panel may be set stepwise in accordance with the wind speed of the outdoor wind. For example, the rotation angle can be reduced as the wind speed increases.

  Thereafter, a timer setting process for determining the execution time of the first automatic ventilation is executed, and the first automatic ventilation start process is ended. Note that the value set in the timer setting process is subtracted every time the ventilation control process is executed, and automatic ventilation is terminated when the value becomes zero.

  The window panel drive units 91 and 92 operate based on the drive signal output in step S105, so that the window panels 51 and 52 are arranged at the optimum positions, and natural ventilation using the window openings 41 and 42 is performed. Is started.

  On the other hand, if a negative determination is made in step S105, that is, if it is determined that the wind speed sufficient for natural ventilation using the window openings 41 and 42 is not secured, the process proceeds to step S107, and the forced fan 94 is used. The 2nd automatic ventilation start process for ventilating is started. In the second automatic ventilation start process, output of a drive signal to the ventilation fan 94 is started, and this ventilation control process is ended as it is. In the second automatic ventilation start process, the same process as the timer setting process is executed.

  Returning to step S102, if an affirmative determination is made in step S102, that is, if it is determined that automatic ventilation is being executed, the process proceeds to step S108. In step S108, it is determined whether it is time to end automatic ventilation. Specifically, referring to the timer value set in the timer setting process, it is determined whether or not the timer value is zero.

  When a negative determination is made in step S108, that is, when it is determined that it is not yet time to end the automatic ventilation process, the process proceeds to step S109, and it is determined whether or not the ventilation process currently being executed is the first automatic ventilation process. judge. If a negative determination is made in step S109, that is, if it is determined that forced ventilation is performed using the ventilation fan 94, the ventilation control process is terminated as it is.

  On the other hand, if an affirmative determination is made in step S109, the process proceeds to step S110 to execute a ventilation amount adjustment process. Specifically, based on the information on the wind direction and the wind speed input from the wind speed sensor 81, it is determined whether or not the current position of each window panel 51, 52 is optimal. If it is determined that the wind direction or wind speed has changed from the timing of starting ventilation and is no longer in an optimal state, the window panel 51, each window panel 51, A drive signal is output to the window panel drive units 91 and 92 so that 52 is arranged at an optimal position. By performing such processing, the window panels 51 and 52 are maintained at a position where the ventilation efficiency is most improved. After performing the process of step S110, this ventilation control process is complete | finished as it is.

  Returning to the description of step S108, if an affirmative determination is made in step S108, that is, if it is determined that it is time to end the automatic ventilation process, the automatic ventilation stop process is executed in step S111. End the ventilation control process.

  In the automatic ventilation stop process, first, the mode of ventilation being executed is grasped, and the return process to the state before the ventilation execution is performed accordingly. Specifically, when the first automatic ventilation is performed, the drive signals are output to the window panel drive units 91 and 92 so that the window panels 51 and 52 are returned to the closed positions, and the second automatic ventilation is performed. When ventilation is performed, the output of the drive signal to the ventilation fan 94 is stopped. When moving each of the window panels 51 and 52 to the closed position, it is preferable to first return the windward side window panel to the closed position and then return the windward side window panel to the closed position.

  As mentioned above, according to embodiment explained in full detail, there exist the following outstanding effects.

  By properly using the first automatic ventilation (natural ventilation) and the second automatic ventilation (forced ventilation) according to the wind speed, it is possible to improve the ventilation efficiency and suppress the consumption of electric power due to it.

  In the case of performing the first automatic ventilation, it is possible to improve the ventilation efficiency by adjusting the positions of the window panels 51 and 52 according to the wind speed, and to shorten the time required for the ventilation of the bathroom 21.

  When the bathroom 21 is used, it is possible to avoid giving a troublesome impression to the user of the bathroom 21 by adopting a configuration in which automatic ventilation is not performed.

  When performing automatic ventilation, the door 39 is forcibly closed, thereby blocking air movement between the bathroom 21 and the dressing room 22 to prevent air leakage to the dressing room 22 side. It is possible to suppress and allow the rectifying function in the bathroom 21 to be suitably exhibited. Thereby, improvement in ventilation efficiency can be expected.

  In an environment where priority is given to ensuring privacy, such as in the bathroom 21, the inside of the bathroom 21 can be hidden from the outdoors by arranging the window openings 41 and 42 as high as possible. However, if the window openings 41 and 42 are arranged at such a high position, it is difficult to manually open the window openings 41 and 42. In this regard, when automatic ventilation is performed, it is not necessary to manually open and close the window openings 41 and 42. Thereby, while protecting privacy, the fall of the convenience resulting from it can be suppressed.

  In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows. Incidentally, the configuration of another embodiment described below may be applied individually to the configuration in the above embodiment, or may be applied in combination with each other.

  (A) In the above embodiment, the window panels 51 and 52 and the curtain 56 are used as the “rectifying means”. However, it is not always necessary to employ a plurality of “rectifying means”, and one of them may be omitted. Is possible. For example, when the rectifying function of the window panels 51 and 52 is omitted, the window panels 51 and 52 can be configured not to rotate indoors but to the indoor side. is there.

  (B) The window openings 41 and 42 only need to be spaced apart at least in the horizontal direction, and can be arranged side by side, for example.

  (C) In the above embodiment, the windward side window opening 41 and the leeward side window opening 42 are formed in the first outer wall part 31 respectively. It is also possible to form a plurality of window openings by partitioning the through hole with a sash frame or a fixed window panel.

  Further, the window openings 41 and 42 are not necessarily closed by one window panel, and may be configured to be closed by a plurality of window panels. For example, each window opening 41, 42 can be configured to be closed by a plurality of window panels arranged side by side in the surface spreading direction of the first outer wall portion 31.

  (D) In the above-described embodiment, the configuration that allows the window panels 51 and 52 to be rotated indoors and the curtain 56 are employed as the “rectifying means”, but the following configuration may be employed instead. Is possible. That is, as shown in the schematic diagram of FIG. 5 (a1), the first inner window panel 101 and the second inner window panel 102 are made to correspond to the first outer window panel 51A and the second outer window panel 52A on a one-to-one basis. Provide. Each of the inner window panels 101 and 102 is composed mainly of a glass plate like the outer window panels 51A and 52A, and is opposed to the outer window panels 51A and 52A from the inside of the bathroom 21 with a gap. ing. As with the outer window panels 51A and 52A, the outer window panels 101 and 102 are formed to match the window openings 41 and 42, and the window windows 41 and 42 are closed by the inner window panels 101 and 102. Yes.

  The outer window panels 51A and 52A are different from the above-described embodiment in that the opening to the outdoor side is allowed when the window openings 41 and 42 are opened, while the turning to the indoor side is not allowed. It has become. On the other hand, for the inner window panels 101 and 102, the end on the same side as the rotation base end side of the opposed outer window panels 51A and 52A is the rotation base end, and the rotation base end The outer window panels 51A and 52A can be turned to the opposite side (indoor side). Note that the rotation range of the inner window panels 101 and 102 is restricted to a maximum of 90 degrees.

  When opening the window openings 41 and 42, as shown in FIG. 5A2, the inner window panels 101 and 102 are turned to the indoor side and the outer window panels 51A and 52A are turned to the outdoor side. This allows outside air to enter and exit through the window openings 41 and 42. About the inner side window panels 101 and 102, the front-end | tip part protrudes from the window openings 41 and 42, and it rectifies | straightens so that air may move along the wall parts 32-34 by the said inner side window panels 101 and 102. It becomes.

  When the configuration shown in this modification is employed, the following configuration may be employed in combination. That is, when the inner window panels 101 and 102 are opened to the indoor side, the window panels so that the outer window panels 51A and 52A rotate based on (in conjunction with) the operation of the inner window panels 101 and 102. It is advisable to employ an interlocking mechanism for interlocking movements between them. Specifically, the outer window panels 51A and 52A and the inner window panels 101 and 102 are connected by a link mechanism made of gears and the like, and the outer window panels follow the rotation of the inner window panels 101 and 102 toward the indoor side. 51A and 52A are comprised so that the same angle as the inner side window panels 101 and 102 may open to the outdoor side. Thus, when performing ventilation, the user turns the inner window panels 101 and 102 to the indoor side, thereby turning the outer window panels 51A and 52A to the outdoor side. Therefore, the fall of the work at the time of ventilation of the bathroom 21 resulting from combined use of the inside and outside window panels can be suppressed. In addition, it is not always necessary to configure the continuous mechanism so that the rotation angle of the inner window panels 101 and 102 toward the indoor side and the rotation angle of the outer window panels 51A and 52A toward the outdoor side are the same. The rotation angle of the inner window panels 101 and 102 is larger than the rotation angle of the outer window panels 51A and 52A, or the rotation angle of the inner window panels 101 and 102 is the rotation of the outer window panels 51A and 52A. It can also be configured to be smaller than the angle.

  Further, in the above-described modification using both the inner and outer window panels, the outer window panels 51A and 52A can be rotated only to the outdoor side. It is good. In the case of such a configuration, the wall portion closest to the rotation center portion (rotation center axis) of the inner window panels 101 and 102 is the rotation center portion (rotation center axis) of the outer window panels 51A and 52A. It is good to shift to the 33, 34 side. Thereby, it can suppress that the inner side window panels 101 and 102 become the obstruction at the time of rotating the outer side window panels 51A and 52A to an indoor side. By adopting such a configuration, the rotation direction of the outer window panels 51A and 52A can be selected indoors and outdoors according to the wind speed, which can contribute to the improvement of ventilation efficiency.

  As shown in the modification (d), when the inner and outer window panels are used in combination, a sealed space is formed between the inner window panel and the outer window panel with both the window panels closed. It is preferable to adopt a configuration. By setting it as this structure, the heat insulation function and soundproofing function of the bathroom 21 can be improved suitably.

  (E) In the above embodiment, the distance between the window openings 41 and 42 is set larger than the lateral width of the window openings 41 and 42, but the present invention is not limited to this. It is also possible to make the distance between the window openings 41 and 42 smaller than the width of the window openings 41 and 42.

  When making such a change, as shown in (b1) of FIG. 5, the rotation angle of the window panels 51B and 52B toward the indoor side may be set to about 90 degrees. In this case, as shown in FIG. 5 (b 2), the outside air flowing in from the windward side window opening 41 is rectified by the leeward side window panel 52 B so as to move along the partition wall portion 34, and from the leeward side window opening 42. The air that flows out is rectified so as to move along the third outer wall portion 33. That is, when one of the two window panels is opened outward and the other is opened inward, the other window panel that is opened inward functions as a rectifier.

  (F) When each of the window panels 51 and 52 is opened, if a lock device that can fix the window panels 51 and 52 at a desired position is employed, the position of the window panels 51 and 52 is changed by wind pressure. It can be made difficult to occur.

  (G) In the said embodiment, although the window opening 41 and 42 was provided in the 1st outer wall part 31 among the outer wall parts 31 and 32 located in the both sides in the longitudinal direction of the bathroom 21, it is not limited to this. A window opening may be provided in the second outer wall portion 32. Furthermore, you may provide a window opening in the 3rd outer wall part which comprises an outer wall among wall parts 33 and 34 located in the both sides in the transversal direction of the bathroom 21. FIG. However, in order to promote the movement of air along the inner wall of the bathroom 21, it is preferable to arrange a window opening on one outer wall portion in the longitudinal direction of the bathroom 21 as shown in the above embodiment.

  (H) In the above embodiment, the bathroom 21 is ventilated. However, the bathroom 21 and the dressing room 22 can be ventilated together. When performing such ventilation, the door 39 of the bathroom 21 is opened to allow the bathroom 21 and the dressing room 22 to communicate with each other, and the door of the dressing room 22 is closed to prevent air from entering and leaving other rooms. Good.

  (I) In the above embodiment, the ventilation structure (ventilation device 60) is applied to the bathroom 21, but the application target of the ventilation structure is not limited to the bathroom, and can be applied to a living room such as a living room. It is.

  (J) In the above embodiment, the ventilation device 60 is constructed using the ventilation structure, the various sensors 81 to 84, the automatic ventilation switch 85, the various drive units 91 to 93, and the control device 70, but at least corresponds to the ventilation structure.
