Description

[Detailed description of the invention] Industrial application field The present invention relates to a ventilation system used in general homes and other places.

Conventional technology Ventilation systems installed in general homes and offices use fans to force ventilation, and most of them have a shutter installed on the indoor side or outdoor side of the fan. The shutter has a structure in which the shutter opens and closes in conjunction with the ON/OFF operation of the power switch of the drive motor.

Problems that the invention aims to solve When ventilating a room, it is necessary to prevent excessive cold or warm air from escaping through forced ventilation during cooling or heating; in this case, natural ventilation is necessary. It is desirable to be able to provide some ventilation. However, in conventional ventilation systems, the opening and closing of the shutter provided at the vent is linked to the drive of the fan, as described above.
It was not possible to open just the shutters.

Please note that the power switch for the fan drive motor
In addition to the one where the ON-OFF operation string and the shutter opening/closing operation string are attached separately so that they can be operated independently of each other, and the ventilation hole on the front of the fan,
Although it has been considered to provide separate vents for natural ventilation on the left and right sides, both methods have had problems such as complicating the device or making the operation complicated.

The purpose of this invention is to solve the above-mentioned problems in ventilation systems, and to provide a ventilation system that allows easy selection and setting of natural ventilation and forced ventilation using a simple device and operation. It is something to do.

Means for Solving the Problems In order to solve the above-mentioned problems, the ventilation system of the present invention includes a forced ventilation path consisting of a fan and a motor, and a power switch for the forced ventilation path located on either the left or right side of the forced ventilation path. a ventilation device main body having a section;
It is equipped with a cover that is removably attached to the front side of the ventilation device body, and has a shutter that opens and closes the ventilation holes by sliding vertically on the back side thereof, and a large number of ventilation holes. It has a rod that reciprocates between predetermined positions, and when one switch is operated, only the first rod is moved from the stopped state, when another switch is operated, the rod is moved and energized, and when the other switch is operated, the rod is moved and energized. It is equipped with a multi-stage pull switch that can be operated to return to the stopped state, and one end is attached to the ventilation device main body on the other side of the forced ventilation path.
A shutter operation bar is provided, the other end of which is connected to the rod of the power switch section, and an engaging section that engages with a predetermined position of the operation bar is detachably provided on the back side of the shutter. That is.

Effect In the above configuration, the power switch section of the forced draft fan in the ventilation device main body has a rod that moves back and forth between predetermined positions by switch operation, and
A multi-stage pull switch is provided in which the rod is only moved from a stopped state by one switch operation, the rod is moved and energized by another one-stage switch operation, and the rod is returned to the stopped state by another one-stage switch operation. An operating bar for opening and closing the shutter for the vent on the back side of the cover provided on the front side of the ventilation device main body is attached at one end to the ventilation device main body, and the other end is attached to the power switch. The shutter is connected to the rod of the power switch section, and an engagement section that can be freely engaged with and detached from the operation bar is provided on the back side of the shutter and engaged with the operation bar. When the rod moves, the other end of the operating bar swings in the vertical direction using one end of the operating bar as a fulcrum, and this swing causes the engaging portion of the shutter to move up and down,
The shutter opens and closes depending on the displacement. If the shutter is closed and the forced ventilation is stopped by one switch operation, and there is only movement of the rod, only the shutter will be opened and a natural ventilation state will be achieved. When the rod is moved and energized, the shutter is opened and the fan in the forced ventilation path is rotated to achieve a forced ventilation state.When the rod is returned to its original position and the energization is cut off by a further switch operation, The shutter closes and the forced ventilation returns to a stopped state.

Example An embodiment of the present invention will be described based on the drawings.

In FIGS. 1 to 6, the ventilation device includes a ventilation device main body 1 and a cover 2 that is detachably attached to the front side of the ventilation device main body 1.

The operation causes the rod 8 to move further downward and is energized, causing the fan 4a of the forced ventilation device 4 to rotate, and by pulling the third stage string 10, the rod 8 is biased by the spring 9. At the same time, the fan 4a of the forced ventilation device 4 stops and returns to the stopped state. Note that the first switch of the power switch section 7
The operations in the switch operations of the first stage and the second stage may be reversed. Next, the front surface 1a of the ventilation device main body 1
An operating bar 11 for opening and closing the shutter 6 on the back side of the cover 2 is located near the upper side of the ventilation opening 3, and its one end 11a is fixed to the front surface 1a, and the other end 11b is attached to the power switch section 7. It is connected to the upper end 8a of the rod 8 and is disposed substantially horizontally via a guide 12. The operation bar 11
As the rod 8 is moved up and down by the operation of the power switch section 7, the substantially horizontal intermediate portion 11c of the rod 8 swings up and down about the guide 12 fixed to the inner wall 1a as a fulcrum.

The vent holes 5 of the cover 2 are formed in the shape of a plurality of horizontally narrow slits with equal widths and intervals. The shutter 6 on the back side is plate-shaped and is fitted in contact with almost the entire back surface of the cover 2 so as to be slidable up and down, and can open and close the vent 5 of the cover 2 by sliding and moving up and down. As shown in FIG.
It is formed by b. When the cover 2 is attached to the ventilator main body 1 on the back side of the shutter 6, the operating bar 1 is located at a position corresponding to approximately the center of the intermediate portion 11c of the operating bar 11.
1 is provided with an engaging portion 13 that can be freely engaged and detached. If the cover 2 is attached to the ventilator main body 1, the engaging part 13 of the shutter 6 is engaged with the operating bar 11, and the power switch part 7 is operated as described above with the string 10, As the first stage switch is operated, the rod 8 is lowered as shown in FIG. It coincides with the vent 5, and in the same way, by operating the second stage switch, the shutter 6 is opened.
is slightly displaced downward and is energized to rotate the fan 4a of the forced draft fan 4, and as shown in FIG.
rises and returns to its original position, the electricity is cut off and the rotation of the fan 4a of the forced draft fan 4 stops, and at the same time, the operating bar 11 returns upward and the shutter 6 is also displaced upward. It returns to its original state and returns to the stopped state in which the shielding portion 6b shields the vent 5 of the cover 2. 14 is a pilot lamp, and 15 is a mounting screw for the cover 2.

The rear part 1d of the ventilation device main body 1 has a cylindrical shape and forms the ventilation opening 3, and a rainwater intrusion prevention plate 1e is integrally provided at the inner lower part of the rear end of the cylindrical shape to prevent rainwater from entering during use. etc. can be prevented from entering.
