Description

[Detailed Description of the Invention] This invention relates to a ventilation system, and more specifically, to a ventilation system that includes both a forced draft and a natural ventilation window that can be opened and closed.

In general, ventilation fans installed in kitchens, living rooms, and other areas use a fan to force ventilation, so when cooling or heating, cold or warm air escapes due to forced ventilation. This results in a large loss of energy.

Therefore, in such cases, there is a need for a ventilation system that can moderately save ventilation so that cold or warm air does not escape unnecessarily, and can also perform forced ventilation if necessary.

The purpose of this invention is to provide a ventilation system that can meet the above demands.

As shown in the attached drawings, the ventilation device according to this invention is equipped with a forced draft fan 12 and a natural ventilation window 7 that can be opened and closed, and a ventilation device main body 1 that is attached to the indoor side of the mouth, and a looper 25. The attachment consists of a rain infiltration prevention member 2 that is attached to the outdoor side of the mouth, and a connecting cylindrical body 3 that connects the member 2 and the main body 1.

This invention will be specifically explained below with reference to illustrated examples.

In Figures 1 to 3, the ventilation system according to this invention has a ventilation system main body 1 attached to the indoor side of the opening, a rain infiltration prevention member 2 attached to the outdoor side of the opening, and a connection between these parts. It consists of a connecting cylindrical body 3.

4 is a synthetic resin casing of the ventilation device main body 1; 5 is a rectangular front wall also made of synthetic resin provided at the front of the casing 4; this has a forced ventilation opening 6 in the center in the longitudinal direction; It also has a pair of natural ventilation windows 7 at both ends.

The forced ventilation opening 6 is formed in a grid shape, and a motor 8 and a fan 10 attached to a drive shaft 9 of the motor 8 are disposed on the rear side thereof.

The motor 8 is activated or deactivated by a switch operation string 11.

Thus, in the central part of the ventilation system, a forced ventilation device 12 consisting of a forced ventilation opening 6, a motor 8, and a fan 10 is provided.

The natural ventilation window 7 consists of a natural ventilation opening 13 connected to the front wall 5, and a shutter part 14 arranged along the back side of the natural ventilation opening 13 and attached to the front wall 5 so as to be movable left and right.

The natural ventilation opening 13 includes a peripheral frame 15, four thick vertical bars 16, four thin horizontal bars 17 connecting these, and a central core 18 connecting the pair of vertical bars 16 in the center. The central core 18 has long holes 1 in the horizontal direction.
9 is open.

Further, the shutter part 14 is made up of a peripheral frame 20, four thick vertical bars 21, and a central core 22 that connects the pair of vertical bars 21 in the center. Supported by 32.

A knob 23 is provided on the central core 22 in a forwardly projecting manner, and this knob 23 projects forward through the long hole 19 of the natural ventilation opening 13.

Here, the width of the vertical bar 16 of the natural ventilation opening 13 and the opening width between these, and the vertical bar 21 of the shutter part 14
and the width of the opening between them are all made equal.

Therefore, by moving the knob 23 within the elongated hole 19 toward the center of the front wall 5, each vertical bar 21 of the shutter portion 14 can be moved closer to the natural ventilation opening 13, as in the window on the right side of FIG. Corresponding to the position of the opening between each longitudinal bar 16, the window is closed.

Conversely, by moving the knob 23 closer to the end of the front wall 5, a part of the shutter 1
Each of the vertical bars 21 of 4 coincides with the position of each vertical bar 16 of the natural ventilation opening 13 and is hidden behind the vertical bars 16, and the window is opened.

In this way, natural ventilation windows 7 provided at both ends of the ventilation system
can be opened and closed by operating a knob 23.

The rain infiltration prevention member 2 is also made of synthetic resin, and the third
As shown in the figure, it consists of a rectangular peripheral frame 24 and a looper 25 made of a large number of horizontal blades installed horizontally on the frame 24, and a gap 26 between the loopers 25 serves as a ventilation passage.

Further, the rain infiltration prevention member 2 is provided with an annular front protrusion 27 at the longitudinal center of the inner surface thereof.

On the other hand, an annular rear protrusion 28 is also provided in the fan storage section at the longitudinal center of the casing 4 .

The connecting cylindrical body 3 connects the ventilation device main body 1 and the rain infiltration prevention member 2 by fitting both ends into the front protrusion 27 and the rear protrusion 28.

The length of the connecting cylinder 3 is determined by the thickness of the wall W.

29 is a screw for attaching the ventilation device to the wall W, 30 is a screw for attaching the front wall 5 to the casing 4, and 31 is an indicator lamp indicating that the forced ventilation device 12 is in an operating state.

In snowy regions, a hood is attached to the outside of the ventilation system to prevent snow from entering the ventilation system.

As described above, since the ventilation system according to this invention is equipped with a forced draft fan 12 and a natural ventilation window 7 that can be opened and closed, it is necessary to avoid strong ventilation during cooling or heating. By stopping the forced ventilation fan 12 and opening the natural ventilation window 7 to perform ventilation only by natural ventilation, it is possible to prevent cold or warm air from escaping more than necessary.

Furthermore, even if the room is not being heated or cooled, if strong ventilation is not required, ventilation can be performed using only natural ventilation as described above.

On the other hand, if you want to perform strong ventilation, use a forced draft fan 12.
can be activated to provide powerful forced ventilation.

Furthermore, if necessary, natural ventilation and forced ventilation can be performed simultaneously.

In this way, according to the ventilation system of this invention, ventilation can be performed by appropriately selecting or using forced draft and natural draft, making it extremely easy to use, and by avoiding unnecessary forced draft, the power consumption can be reduced. Reducing consumption can also be a distant relative.

In addition, the ventilation device according to this invention includes a ventilation device main body 1 that is attached to the indoor side of the mouth, a rain infiltration prevention member 2 that is attached to the outdoor side of the mouth, and a connection that connects the member 2 and the main body 1. Since it consists of a cylindrical body 3, it is possible to securely and firmly attach the ventilation device to the opening, and there is no risk of it coming off the opening.In addition, the rain infiltration prevention member 2 prevents rainwater from entering the opening. Infiltration can be completely prevented.
