Abstract

PURPOSE:To improve the outside view and eliminate the need for the cost of material and work required to mount a hood by forming a hood outdoors by a shutter plate and a shutter side plate when a shutter is rotated upward during the drive of a ventilating fan, and housing the entire shutter within a frame during the suspension of said ventilating fan. CONSTITUTION:When operation starts by an operation switch, a wire 8 is lowered so that an operation plate 4 may rotate in a direction depicted by the arrow A. Interlocked with the above operation, a support shaft 3 rotates so that a shutter 2 may rotate in a direction depicted by the arrow B, thereby ventilating. The shutter 2 forms a hood outside an outdoor side wall surface with a shutter plate 2a and a shutter side plate 2b, and prevents the penetration of rain indoors slantingly from above. The rain penetrates a clearance 7 of a frame member 1 along the shutter side plate 2b, cut it can not penetrate further inside. Therefore, the penetration of rain and water can be prevented without the installation of a separate hood. Furthermore, any thing which projects from the outdoor side wall surface can be eliminated even when the ventilating fan is suspended.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a wall-mounted ventilation fan used primarily in homes.

Conventional Technique FRT Light 2 ・＼-) Conventionally, this type of ventilation fan had a configuration as shown in FIG. 3. That is, the shutter 12 is fitted into the outdoor opening 11a of the ventilation fan 11, and the shutter 12 is opened in conjunction with the pulling operation of the pull cord (not shown), and the electric motor is operated to rotate the blades and exhaust indoor air. or supply outdoor air. However, since the shutter 12 and the outdoor opening 11a do not have any protection against rain from blowing in from diagonally above, generally a hood 13 is attached to the outdoor side as shown in FIG. It prevented infiltration.

Problems to be Solved by the Invention In such a conventional configuration, the hood 13 protrudes from the outdoor wall surface, which often seriously impairs the aesthetic appearance of modern buildings. Also, the construction costs to install it were not cheap.

The present invention is intended to solve these problems, and aims to improve the aesthetic appearance of buildings and eliminate the need for capital and construction costs for installing a hood.

Means for Solving the Problem In order to solve this problem, the present invention provides a shutter plate that opens and closes the outdoor space ``1'' and a shutter plate that is integrated with both ends of the shutter plate at the outdoor opening of the frame of the ventilation fan main body. A shutter consisting of a fan-shaped shutter side plate provided on the frame is rotatably provided on a support shaft rotatably provided on the upper part of the frame, and an actuating plate is fixed to one end of the support shaft so as to be rotatable in the vertical direction. ,
A spring biased to always rotate upward and a shutter opening/closing device that pulls downward to open the shutter are connected to this operating plate, and the shutter side plate is connected to a partition plate inside the side plate of the frame body. The ventilation fan is placed in the gap formed by the ventilation fan.

With this configuration, when the ventilation fan is operated, the shutter rotates upward to open the outdoor opening, and the shutter plate and the shutter side plate form a lid on the outdoor side, and the mountain blows against the shutter, causing the shutter side plate to open. Even if it passes through the frame and enters the frame, it will not enter the interior through the gap.

On the other hand, when the ventilation fan is stopped, the entire shutter is housed within the frame, and there is no protrusion from the outdoor wall surface.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2. In FIG. 1, 1 is a frame of the ventilation fan main body, which forms the ventilation path of the ventilation fan.

The outdoor side opening 1a of this frame 1 has an outdoor side opening 1a.
A shutter 2 consisting of a shutter plate 2a that opens and closes and fan-shaped shutter side plates 2b integrally provided at both ends of the shutter plate 2a is rotatable by a support shaft 3 rotatably provided at the top of a frame 1. It is set in. Support shaft 3
An actuating plate 4 is provided at one end of the actuating plate 4, which is fixed at one end and is rotatable in the vertical direction. The other end of the actuating plate 4 has one end fixed to the frame body 1 and the other end of a spring 5 which is always biased upward, and the other end of a spring 5 which is attached to the lower part of the frame body 1 and is connected to the electric motor and moves up and down. Operation switch (5, - shown).

The wire 8 connected to the wire (not shown) is connected. A partition plate 6 having approximately the same shape as the side plate 1b is arranged inside the side plate 1b of the frame 1 to form a gap 7 partitioned from the inside of the frame 1. 2
b, and the shutter side plate 2b rotates to fill this gap 7.
They come in and out from.

When the ventilation fan configured as described above starts operating by pressing the operation switch, the wire 8 is pulled and the actuating plate 4 rotates in the direction of arrow A, and in conjunction with this, the support shaft 3 rotates. ,
The shutter 2 rotates in the direction of arrow B and opens, and ventilation is performed. The shutter 2 forms a hood from the outdoor side wall surface to the outside by the shutter plate 2a and the shutter side plate 2b, and prevents rain from entering the indoor side from diagonally above. In addition, although the rain passes through the shutter side plate 2b and enters the gap 7 of the frame 1, it does not enter the inside of the frame 1, thereby reliably preventing rain from entering the room.

In this way, it is possible to prevent rainwater from entering the room without installing a separate hood, and it is also possible to eliminate anything protruding from the outdoor wall when the ventilation fan is stopped.

Effects of the Invention As is clear from the description of the embodiments above, according to the present invention, the shutter also has the function of preventing rainwater from entering the hood, so there is no need to separately install a hood that protrudes to the outside of the building. The effect is that the aesthetic appearance of the building is not impaired, and the cost of materials and construction required for installing the hood is not required.
