DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilating apparatus mainly mounted on a wall of a room such as a home or an office.

[0002]

2. Description of the Related Art Conventionally, this type of ventilator is generally shown in FIG.
As shown in FIG. 3, an opening 10 is formed in the room wall 101 so as to be inclined downward toward the outdoor 102 side.
3 and communicates between the room 104 and the outdoor 102, and the body 102 has the outdoor 102 side inclined downward.
A substantially box-shaped outdoor hood 107 provided with an air supply or exhaust opening 106 on the lower surface is provided on the outdoor 102 side of 05. In the outdoor hood 107, the outer peripheral portion of an annular cylindrical portion 109 protruding from the periphery of the hood hole 108 opened on the front side toward the room 104 is fitted to the inner peripheral portion of the outdoor-side opening portion 110 of the main body cylindrical portion 105. And a plurality of fixing portions 111 projecting outward from the peripheral edge of the front surface.
It is attached by being fixed to the room wall 101 at 12. Also, on the indoor 104 side in the main body cylindrical portion 105,
A ventilation fan 113 for exhaust or air supply is mounted.

In the above configuration, a ventilation fan 113 for exhausting air
, Dirty air in the room 104 is sucked into the exhaust ventilation fan 113, passes through the inside of the main body cylindrical portion 105 and the inside of the outdoor hood 107, and is discharged from the opening 106 to the outside 102. When the ventilation fan 113 for air supply is mounted on the main body tubular portion 105 instead of the ventilation fan 113 of the operation, the fresh air in the outdoor 102 is discharged by the ventilation fan 11.
Then, the air is supplied to the room 104 from the ventilation fan 113 through the opening 106 and the inside of the outdoor hood 107 and the inside of the main body tubular portion 105. In addition, the main body cylinder 10
The outdoor hood 107 can prevent rainwater or outside wind from entering the inside of the vehicle.

Then, a room 104 to be ventilated and an outside 102 are ventilated.
When the temperature difference between the main body and the main body is large, or when the ventilator is installed and used in a humid place such as a bathroom, a large amount of dew is generated inside the main body cylindrical portion 105, Because the outdoor 102 side is inclined downward, the dew condensation water flows down to the outdoor 102 side through the inside of the main body tubular portion 105 without flowing into the room 104, and passes through the cylindrical portion 109 of the outdoor hood 107. As a result, the air is discharged from the opening 106 to the outside 102.

[0005]

In such a conventional ventilator, although the dew water generated inside the main body tube portion 105 is surely prevented from flowing into the room 104, the room of the main body tube portion 105 is prevented. Since the outer peripheral portion of the cylindrical portion 109 of the outdoor hood 107 is fitted to the inner peripheral portion of the outer opening 110,
Part of the dew water flowing into the cylindrical portion 109 from the main body cylindrical portion 105 passes through the gap between the fitting portions between the main body cylindrical portion 105 and the cylindrical portion 109, and the opening 103 of the chamber wall 101 and the main body There is a problem in that the water penetrates into the narrow gap between the cylindrical portions 105 and between the room wall 101 and the front surface of the outdoor hood 107 to corrode the room wall 101.

[0006] The outdoor hood 107 has a cylindrical portion 1.
09 is fitted to the inner peripheral surface of the cylindrical main body tube portion 105, and the fixing portion 111 is attached to the chamber wall 1 with a wood screw 112.
01, the opening 106 may be staggered upward or sideways when the outdoor hood 107 is attached.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, and reliably prevents dew water generated inside a main body cylinder from leaking from a fitting portion between the main body cylinder and an outdoor hood to corrode a chamber wall. It is a first object to provide a ventilating apparatus capable of performing the above-described operations.

[0008] A second object is to reliably prevent a wrong installation direction of the outdoor hood.

[0009]

A first means for achieving the first object of the present invention is inserted and installed from the indoor side into an opening formed in a room wall, and communicates between the indoor and the outdoor. A main body cylindrical portion having a cylindrical shape and an outdoor side inclined downward, a blower disposed inside the main body cylindrical portion and exhausting room air or supplying outdoor air; and a chamber of the main body cylindrical portion. A ventilating device fitted with an outer peripheral portion and having an outdoor hood having a bottomed cylindrical shape covering an outdoor opening portion of the main body cylindrical portion and having an air supply or exhaust opening at a lower portion of the outdoor outer peripheral portion; The configuration is as follows.

The second means for attaining the second object corresponds to the main body fixing portion provided at one position off the center of the outdoor opening of the main body cylindrical portion of the first means. A hood fixing portion is provided on the outdoor hood, and a fixing device is provided between the fixing portions to form a ventilation device in which the outdoor hood is attached to the main body cylindrical portion.

[0011]

According to the first aspect of the present invention, even if the dew water generated inside the main body cylinder flows into the gap between the fitting part between the main body cylinder and the outdoor hood, the first means and the main body cylinder can be used. The outdoor hood is inclined downward at the outdoor side, and the inner peripheral part of the outdoor hood is fitted to the outer peripheral part of the main body cylinder, so that the outdoor hood can be reliably supplied through the outdoor hood without flowing backward to the indoor side. It will be discharged outside the room from the exhaust port.

According to the configuration of the second means, when the inner peripheral portion of the outdoor hood is fitted to the outer peripheral portion of the main body cylindrical portion, and the hood fixing portion is aligned with the main body fixing portion and fixed, the fixing direction is as follows. Since it is determined on one side, the air supply or exhaust opening is always located downward.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

As shown in the figure, an indoor wall 1 is inserted and installed in an opening 3 which is opened so as to be inclined downward toward the outdoor 2 side. A horn-shaped flange portion 6 extends outward along the chamber wall 1 around the outer periphery of the end of the cylindrical main body tube portion 5 whose two sides are inclined downward at the room 4 side. A grill 8 that covers the indoor opening 7 of the main body cylindrical portion 5 is detachably attached to the outer peripheral portion. A blade 9 and an electric motor 1 for driving the blade 9 are provided on the indoor 4 side inside the main body tubular portion 5.
An exhaust blower 12 including an air blower 0 and an orifice 11 for guiding air to the blade 9 is provided.

A thin rod-like connecting plate 14 is provided between the upper and lower ends of the main body cylinder 5 on the outdoor 2 side, and the connecting plate 14 is provided with respect to the center of the outdoor opening 13. A first boss 15 which is a main body fixing portion that is disengaged upward is provided. An outer hood 1 having a bottomed cylindrical shape that covers the outdoor opening 13 of the main body tube portion 5 is provided on an outer peripheral portion of the main body tube portion 5 on the outdoor side.
6 has an inner peripheral portion fitted therein, and its indoor 4-side end 16A.
Facing the interior of the room wall 1. At the rear of the outdoor hood 16, a second boss 17, which is a hood fixing portion that matches the first boss 15 of the main body cylinder portion 5, is provided to protrude toward the room 4. Is fixed by the fixing screw 18, so that the outdoor hood 16 is attached to the main body tubular portion 5. Further, an opening 19 for exhaust is provided in a lower portion of an outer peripheral portion of the outdoor hood 16 on the outdoor 2 side.

In the above configuration, when the exhaust blower 12 is operated, the dirty air in the room 4 is sucked by the blades 9, passes through the grill 8, the orifice 11, the inside of the main body tube 5, and the inside of the outdoor hood 16, and opens. From 19, it is discharged to the outdoor 2. In addition, the outdoor hood 16 can prevent the rainwater or the outside wind on the outdoor 2 side from entering the inside of the main body tubular portion 5.

If the temperature difference between the indoor room 4 and the outdoor room 2 to be ventilated is large, or if a ventilation device is installed in a humid place such as a bathroom, a large amount of air will be left inside the main body tube portion 5. However, since the outside of the main body tube portion 5 is inclined downward, the condensed water flows down the inside of the main body tube portion 5 to the outside 2 side without flowing into the room 4. Then, the air is discharged from the opening 19 to the outside 2 through the outdoor hood 16. Further, even if the dew condensation water penetrates into a narrow gap between the fitting portion of the main body tube portion 5 and the outdoor hood 16, the outdoor side of the main body tube portion 5 and the outdoor hood 16 is inclined downward, and Since the inner peripheral portion of the outdoor hood 16 is fitted to the outer peripheral portion, the dew condensation water does not directly touch the room wall 1,
In addition, there is no backflow to the indoor 4 side, and the air is reliably discharged from the opening 19 to the outdoor 2 through the inside of the outdoor hood 16.

As described above, according to the ventilating apparatus of the embodiment of the present invention, the dew condensation water generated inside the main body tubular portion 5 leaks from the fitting portion between the main body tubular portion 5 and the outdoor hood 16 and the wall of the room. 1 can be reliably prevented from corroding.

Further, a second boss 17 is provided on the outdoor hood 16 so as to match the first boss 15 provided above and off the center of the outdoor opening 13 of the main body cylindrical portion 5.
Since the outdoor hood 16 is attached to the main body tubular portion 5 by fixing the space between 5 and 17 with the fixing screw 18,
When the outdoor hood 16 is attached to the main body tubular portion 5, the outdoor hood 16 does not rotate in the rotation direction of the fixing screw 18, so that the mounting direction of the outdoor hood 16 is determined in one direction, and the opening 19 is always positioned downward. Will be done.

As described above, according to the ventilating apparatus of the embodiment of the present invention, it is possible to reliably prevent the mounting direction from being wrong when the outdoor hood 16 is mounted, and to improve the efficiency of the mounting operation.

In the embodiment, the case where the exhaust air blower 12 is provided in the main body cylindrical portion 5 and the dirty air in the indoor 4 is exhausted to the outside 2 to ventilate the indoor 4 has been described. Instead, an air supply blower for supplying fresh air from the outside 2 to the room 4 may be provided instead of the exhaust blower 12, so that there is no difference in the operation and effect.

Further, the bosses 15 and 17 for attaching the outdoor hood 16 to the main body tubular portion 5 are provided at positions deviated upward from the center of the outdoor-side opening portion 13. However, the present invention is not limited to this. The bosses 15 and 17 may be arranged off the center of the outdoor opening 13, so that there is no difference in the operation and effect.

[0023]

As is apparent from the above embodiment, according to the present invention, the outdoor opening of the main body cylindrical portion is covered on the outer peripheral portion of the cylindrical main body cylindrical portion whose outdoor side is inclined downward. By fitting the inner periphery of the bottomed cylindrical outdoor hood,
It is possible to provide a ventilator that can reliably prevent the dew water generated inside the main body cylinder from leaking out from the fitting portion between the main body cylinder and the outdoor hood and corroding the room wall.

Further, a hood fixing portion fixed to a main body fixing portion provided at a position deviated from the center of the outdoor opening portion of the main body cylindrical portion is provided on the outdoor hood, and the fixing portion is fixed between these fixing portions. Since the outdoor hood is attached to the main body cylindrical portion, it is possible to reliably prevent a mistake in the mounting direction of the outdoor hood.
