[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ventilation device used for indoor ventilation of a living room, a kitchen, a bathroom or a toilet in a general house, a temporary house or the like.

[0002]

[Prior art]

 Conventionally, in general houses and temporary buildings such as shower rooms, shops, and toilets, ventilation fans for indoor ventilation are installed on the walls and windows, but the exhaust direction is outside the axial direction of the ventilation fan. Yes, depending on the installation position of the ventilation fan, the height of the person outside the building or the height of the window of the adjacent building may cause the exhaust air from the ventilation fan to interfere with people and others. There were cases.

[0003]

[Problems to be solved by the device]

 In consideration of the problems of conventional ventilation fans used in general houses and temporary housing, the present invention configures a casing that integrates a ventilation fan mounting portion and a duct extending in the ventilation direction to form a ventilation fan. Regardless of the position of the building's ventilation port, the exhaust direction can be set to a position that does not hinder people or other things, and it is a single-piece structure that can be easily installed and removed. It is intended to provide a ventilation system that can be performed.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the ventilation device according to the present invention comprises a casing in which a mounting portion of the ventilation fan and a duct extending in the ventilation direction are integrated, and the ventilation fan is mounted on the mounting portion of the ventilation fan. An exhaust hole is provided on the end face in the exhaust direction.

[0005]

[Action]

 According to the ventilator of the present invention, a casing in which the attachment portion of the ventilation fan and the duct extending in the exhaust direction are integrated is configured, and the ventilation fan is attached to the attachment portion of the ventilation fan of this casing. Therefore, the duct can set the exhaust direction of ventilation by the ventilation fan to a suitable position without being restricted by the position of the ventilation port of the building. Further, the exhaust positions can be dispersed.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a casing, which is composed of a hollow body formed by blow molding a thermoplastic resin, and has a ventilation fan mounting portion 2 below and a duct 3 extending upwardly. Is configured. A ventilation fan 4 is attached to the attachment portion 2 of the ventilation fan.

A back surface 5 of the casing 1 is a flat surface, and a mounting portion 2 of the ventilation fan has a fan fitting recess 7 formed in a recess 6 recessed inward from the back surface 5. The fan fitting recess 7 is open to the hollow portion through a circular opening 8 and communicates with the duct 3. A cover 10 is connected to the lower end of the fan mounting portion 2 by a compression-thinned hinge 9 so as to be openable and closable, and the cover 10 has a fan fitting recess 11 for mating with the fan fitting recess 7. The fan fitting recess 11 is provided with a circular opening 12. By fitting the cover 10 to the recessed portion 6 by the hinge 9, the ventilation fan 4 fitted in the fan fitting recess 7 is sandwiched and fixed. The cover 10 locks and holds the latch 14 on the latch receiving portion 13. The cover 10 has a flange 17 that fits into the ventilation port 16 of the building wall 15, and the ventilation fan 4 is fixed to the ventilation port 16 of the building wall 15 by the flange 17. Reference numeral 18 denotes a mounting bracket, and the casing 1 is mounted on the wall 15 of the building with screws or the like by the mounting bracket 18.

On the other hand, the upper end surface 19 of the duct 3 forms a flat surface having the same width as the front-rear width of the duct 3, and an inclined surface 20 is formed so as to extend obliquely downward and forward from the front end of the upper end surface 19. The upper end of the duct 3 is a space 22 having a larger volume than the passage 21 of the duct 3. In addition, the duct 3 is formed with a rib 3a that projects toward the passage portion 21 and extends in the air blowing direction to prevent deformation of the casing including the guide for air blowing air and the attachment portion 2 of the ventilation fan 4. There is. The upper end surface 19 is provided with an upward exhaust hole 23, and the lower end surface 24 of the inclined surface 20 is provided with an exhaust hole 25. A solar cell 26 is provided outside the inclined surface 20, and the solar battery 26 supplies electric power for driving the ventilation fan 4. Reference numeral 27 indicates wiring for that purpose. The drive power of the ventilation fan 4 may be supplied from another power source instead of the solar cell 26. In order to increase the power generation efficiency of the solar cell 26, it is desirable to set the angle of the inclined surface 20 with respect to the horizontal plane to be equal to or close to the latitude of the installation location. 28 is a drain hole for drainage.

The thermoplastic resin forming the casing 1 is polyethylene, polypropylene, polyvinyl chloride, ABS resin or the like suitable for blow molding.

According to the ventilator according to the embodiment configured as described above, the casing 1 in which the ventilation fan mounting portion 2 and the duct 3 extending in the exhaust direction are integrated is a hollow body formed by blow molding. Since the ventilation fan 4 is attached to the ventilation fan attachment portion 2 of the casing 1, the exhaust direction of ventilation by the ventilation fan 4 can be positioned above by the duct 3. For this reason, the exhaust can be performed at a position that does not interfere with people or other things without being restricted by the position of the ventilation port 16 of the building. Further, the exhaust flow that has flowed into the space 22 through the passage 21 of the duct 3 is exhausted from the exhaust holes 23 and 25 provided in the upper end surface 19 and the lower end surface 24 of the inclined surface 20, respectively, so that the exhaust position is It is dispersed and the exhaust air pressure can be lowered. In particular, since the volume of the space 22 is larger than that of the passage 21 of the duct 3, the wind pressure of the exhaust flow in the space 22 becomes low, and the exhaust wind pressure from the exhaust holes 23, 25 can be further reduced. it can. In the embodiment described above, an example of ventilating from the inside to the outside of the building has been shown.However, the ventilator according to the present invention ventilates from the outside to the inside of the building, and the space partitioned inside the building, etc. Can also be used for ventilation between other spaces. Further, the positions and numbers of the ventilation holes 23 and 25 are not specified in the illustrated example, and the ventilation holes can be formed in the side wall. Further, the casing 1 does not necessarily have to include the cover 10, and the ventilation fan 4 can be attached to the casing 1 without using the cover 10.

[0011]

[Effect of device]

 According to the present invention, a casing in which a ventilation fan mounting portion and a duct extending in the ventilation direction are integrated is configured so that the ventilation direction can be set to a person or another regardless of the ventilation port position of the building where the ventilation fan is located. On the other hand, the position can be set so that it does not cause any obstacle, but the structure is integrated, and the effect that it can be easily attached or removed is obtained.
