Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window device with a ventilation function that forcibly exhausts indoor air.

The offensive odor generated when the care receiver changes diapers causes pain not only to the care receiver but also to the care workers. Therefore, it is required to remove the offensive odor from the room where the care recipient's bed is located to the outside.

In the exhaust system disclosed in Patent Document 1, the suction port of the exhaust equipment is arranged on the ceiling, and the discharge port of the air conditioner is also arranged at a position away from the suction port. A bed on which the cared person sleeps is placed right under the suction port of the exhaust device. Air containing a bad smell in the vicinity of the person being cared for is exhausted outside the room from the suction port on the ceiling.

Patent Document 2 discloses a window device with an exhaust fan for use in a constant ventilation system. This window device is installed in a wall opening in an outer wall of a toilet room or the like. When the exhaust fan is driven, dirty air in the room is discharged to the outside. As a result, not only the toilet room but also the living room have a negative pressure, and fresh outside air is introduced into the living room and the toilet room from the air supply port formed on the outer wall of the living room.

As schematically shown in FIG. 3, drain holes 13x are formed in both ends of the lower frame portion 13 of the window frame 10 so as to penetrate vertically. Drainage guides 50 are installed at both ends of the space 45 . The internal space of the drainage guide 50 is provided as a drainage channel 51 through which water that has fallen from the drain hole 13x passes. The drainage guide 50 separates the drainage channel 51 from the space 45 beside it. The lower end of the drainage channel 51 is open at both ends of the gap 47, and a grid 52 is attached to the lower end opening.

The operation of the window device 5 with a ventilation function having the above configuration will be described. Normally, the operation member 24d of the ventilation frame 24 is operated to slide the operation plate 24c, and the ventilation port 24y is opened and closed as required. When the vent 24y is open, fresh outside air is supplied into the room through the vent 24x.

When it is required to remove an offensive odor generated in the vicinity of the care-receiver A, such as when changing diapers, the exhaust fan 35 is operated with the operation plate 24c in the open position. Then, the air in the vicinity of the cared person A passes through the air intake introduction path 40 under the bottom wall 34b of the second cover 34, enters the housing 31 from the suction port 34x, and is sucked from the suction portion 35a of the exhaust fan 35. is discharged from the discharge portion 35b. The air discharged from the discharge part 35b of the exhaust fan 35 is discharged to the outside through the exhaust path 45x.

The operation of the exhaust fan 35 creates a negative pressure in the room, so that fresh outside air is naturally supplied into the room through the air passage 24x of the ventilation frame 24. - 特許庁Since the ventilation path 24x and the suction port 34x of the exhaust unit 30 are separated vertically, an air flow indicated by an arrow in FIG. 1 is generated in the room. That is, the outside air supplied from the ventilation frame 24 of the sliding door 20 passes around the care-receiver A lying on the bed B and is discharged from the exhaust unit 30 to the outside of the room. As a result, the air containing the offensive odor in the vicinity of the care-receiver A can be discharged efficiently and quickly.

Since the suction port 34x and the ventilation frame 24 are spaced apart by 400 mm or more as described above, there is no short circuit such that the outside air supplied to the room reaches the exhaust unit 30 directly without passing around the person A being cared for. It is possible to avoid the formation of a circuit (so-called short circuit), and to reliably discharge the air containing the odor in the room. If the suction port 34x and the ventilation frame 24 are spaced apart from each other by 1000 mm or more, the air containing the offensive odor can be more reliably discharged.
In addition, it is preferable that the exhaust fan 35 has the ability to create a negative pressure of 7 pa or more in the room, and that the velocity of the air supplied from the ventilation frame 24 is 0.3 m/sec or more.

The air intake port 34x is formed in the bottom wall 34b of the housing 31 facing away from the ventilation frame 24, and the air intake passage 40 directs the inhaled room air laterally. It can pass around caregiver A.

When the wind and rain are strong, the raindrops hitting the sliding door 20 accumulate in the lower frame portion 13 of the window frame 10, but this water passes through drain holes formed at both ends of the rails 13a and is formed vertically in the lower frame portion 13. The drain guide 50 separates the drainage channel 51 from the space 45 on the side of the drainage channel 51 through the drainage hole 13x, and flows downward through the drainage channel 51 of the drainage guide 50. Therefore, it is possible to avoid going to the exhaust section 30 through this space 45 . In particular, it is possible to avoid going to the exhaust fan 35 through the exhaust path 45x in the central portion of the space 45. - 特許庁As a result, it is possible to reliably prevent water from entering the room.

The present invention is not limited to the above embodiments, and various modifications can be adopted without departing from the scope of the invention.
The exhaust housing may be integral with the lower frame portion of the window frame.
The upper frame of the sash door may serve as a ventilation frame.
A sash door that is opened and closed by rotation may be used instead of the sliding door.
