Description

Rotary control device of non-powered fan {rotary control device of ventilator}

The present invention is installed to rotate on the roof of the building material is rotated by a driving force of the drive motor when the non-powered ventilator (ventilator) to inhale and ventilate the muddy air, smoke, etc. inside the building during rotation is weak. For example, the present invention relates to a rotation control device of a non-powered fan that can be rotated by wind speed when the wind power is strong.

More specifically, the driven rotating body is installed to be rotatable by frictional contact with the driving rotating body integrally formed with the non-powered fan, and the drive for rotating the non-powered fan when the torque of the driving rotating body according to the rotational speed of the fan is higher than the set value. Automatically turn off the power of the motor, and if the wind power is weak and the torque of the driving rotor is below the set value, the power of the driving motor is turned on to force the rotation of the non-powered fan. It is about.

In general, a non-powered fan is installed on the roof of a residential high-rise building so as to inhale and discharge the odor or muddy air such as food smell, toilet, and the like inside the building.

As schematically shown in FIG. 3, the non-powered fan according to the prior art is rotated by a cylindrical member 1 installed on the roof of a building or the like, and a plurality of curved pieces 2 on the cylindrical member 1. Rotating material is mounted on the main rotating body (3) to be mounted and the rotating piece (4) on the main rotating body (3) and the rotating blade (4) in the opposite direction of rotation, and the main rotating body (3). It is provided with an auxiliary rotating body (5) rotated separately with respect to).

Therefore, according to the wind speed, the curved piece 2 of the main rotating body 3 rotates in one direction to inhale and ventilate the muddy air of the room, and the auxiliary rotating body 5 rotates even when the wind is weak. To purify the indoor air.

However, such a non-powered fan can perform its own function of purifying the air inside the building by rotating itself by the wind speed under strong wind conditions, while the windless or weak wind power does not allow the non-powered fan to rotate itself. In the case of not being able to do it, especially in a closed toilet, the ventilation is not made smoothly, so that the odor is not discharged in a timely manner, so that the tenant suffers from the inconvenience of having to live in poor environmental conditions.

In consideration of this, a timer is mounted and used so that power is supplied to the driving motor and the powerless fan is forcibly rotated during the time set by the user.However, the time zone and the non-powered fan driven by the driving motor are set by the timer. If the wind blowing time is strong enough to rotate, there is a problem that the power to drive the non-powered fan is unnecessary.

Accordingly, an object of the present invention is to provide a non-powered ventilator that automatically cuts off the power of the drive motor for the non-powered ventilator when the wind power is strong enough to rotate the non-powered ventilator to prevent unnecessary power consumption. It is to provide a rotation control device.

Another object of the present invention, when the wind power is weak enough that the non-powered fan can not rotate by itself, by automatically connecting the power of the drive motor by forcibly rotating the non-powered fan can create a pleasant environment by smoothly ventilating the indoor air It is to provide a rotation control device of the non-powered fan.

Still another object of the present invention is a pair of rotors that detect the strength and weakness of wind power by mutual frictional force, even when their contact surfaces are worn, continuously maintaining the frictional force in the initial state, so that no after-care is required for the rotation of a non-motor fan. It is to provide a control device.

It is formed into a conical shape.

According to a preferred embodiment of the present invention, the on / off switch for detecting the wind speed may include: a first state of turning off the power of the driving motor due to the pressing of a button contacting the lever when the torque of the driving rotor is greater than or equal to the set value according to the strength of the wind; When the torque of the drive rotary body is less than or equal to the set value, a button-type switch for driving to have a second state for maintaining an initial state for turning on the power of the drive motor is used.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, which are intended to be described in detail to be easily carried out by those skilled in the art to which the present invention pertains, and thus the present invention It does not mean that the technical spirit and scope of the company is limited.

As shown in Fig. 1 and 2, the rotary shaft 11 is fixed to the support frame 13 installed on the roof of the building, such as apartments, buildings, etc. by the bearing 19, and the upper end of the rotary shaft 11 A fan 10 which is fixed to the fan 10 so as to forcibly rotate the non-powered fan by the wind speed or the rotational force of the driving motor according to the wind power sensed in one direction, and a drive motor for driving the power-driven fan by forcibly turning it on when the power is applied. It is applied to the rotation control device of the non-powered fan having a.

Therefore, according to a preferred embodiment of the present invention, the drive rotary body 12 and the drive rotary body which is integrally fixed to the other end of the rotary shaft 11 of the fan 10 to rotate in conjunction with the above-described rotation of the fan 10, A driven rotary body 14 which is seated on the support frame 13 described above so as to rotate in frictional contact with the driven shaft 12 and selectively rotates by a mutual frictional force with the driving rotary body 12 according to the strength and weakness of wind power. ).

In addition, when the torque of the drive rotary body 12 according to the strong rotational force of the fan 10 is in contact with the lever 15 fixed to one side of the driven rotary body 14 or more (the driven rotary body 14 is the drive rotation) When the whole 12 and the power can be rotated by mutual frictional force by the wind. The power applied to the driving motor for the non-powered fan is turned off, and the torque of the driving rotor 12 is less than the set value (the driven rotor). (14) can not be rotated by the mutual frictional force by the driving rotor 12 and the wind) wind speed on / off switch 17 for turning on (ON) the power applied to the drive motor.

At this time, the cross-sectional shape of the site where the above-mentioned driving rotary body 12 and the driven rotary body 14 are in frictional contact may cause the driving rotary body 12 to pressurize the driven rotary body 14 even when the contact surfaces 12a and 14a are worn. It is preferable to form a triangular or trapezoidal conical shape so as to maintain the mutual frictional force in the initial state.

In addition, the on / off switch 17 for wind speed detection described above, when the torque of the drive rotary body 12 is greater than or equal to the set value according to the strength of the wind, due to the pressing of the button 18 in contact with the lever 15 of the drive motor It is preferable to use a button-type switch for driving to have a first state of turning off the power and a second state of maintaining an initial state of turning on the power of the driving motor when the torque of the driving rotor 12 is less than or equal to the set value.

Hereinafter, the method of using the rotation control apparatus of the non-powered fan according to the present invention will be described with reference to the accompanying drawings.

As shown in FIG. 2, the above-described fan 10, which is fixed to the support frame 13 installed on the roof of a building such as an apartment, by means of a bearing 19, rotates in one direction by wind power, and thus, no power is applied. The indoor air can be purified by inhaling the air in the building and venting it into the atmosphere.

At this time, when the above-described fan 10 rotates rapidly in a strong wind, the rotational force of the fan 10 is greater than the frictional force generated between the driving rotary body 12 and the driven rotary body 14, When the driving rotary body 12 fixedly integrally fixed to the lower end of the rotating shaft 11 of one fan 10 rotates in frictional contact with the driving rotary body 12, the driven rotary body 12 is driven by mutual frictional force with the driving rotary body 12. Rotate in one direction.

Accordingly, the lever 15 integrally formed on the outer circumferential edge of the driven rotary body 14 presses the button 18 of the on / off switch 17 for detecting the wind speed, which is installed on the support frame 13 to contact the terminal ( Even when S1) is disconnected and the power applied to the drive motor is automatically disconnected, the fan 10 is continuously rotated by the wind speed, so that the mutual frictional force is continuously maintained between the drive rotary body 12 and the driven rotary body 14. Can be generated.

As a result, when the fan 10 rotates at a high speed such that mutual friction is generated between the driving rotor 12 and the driven rotor 14 according to the wind speed, that is, driving in a strong wind. It is possible to purify the indoor air by rotating the non-powered fan by the wind speed without using the driving force of the motor.

On the other hand, even when the wind is not blown at all, or the wind is weak (when the wind is), even when the fan 10 is rotated, the mutual frictional force does not occur between the above-described driving rotor 12 and the driven rotor 14. In other words, when the rotational force of the fan 10 is dissipated upon transmission to the driven rotating body 14 through the driving rotating body 12 (the rotating force of the fan 10 is between the driving rotating body 12 and the driven rotating body 14). Is generated less than the frictional force of the above-mentioned contact terminal (S1) of the on / off switch 17 for detecting the wind speed is to maintain the initial state that the power is applied to the drive motor is to forcibly rotate the non-powered fan.

Therefore, when the wind is not blown or the wind is weak, the power is automatically applied to the driving motor to rotate the non-powered fan forcibly to clean the air inside the building to create a comfortable environment.

As mentioned above, according to a preferable embodiment, it has the following advantages.

When the wind is strong enough to rotate the non-powered fan, the power of the drive motor for the non-powered fan can be automatically cut off to prevent unnecessary power consumption.

If the wind speed is weak enough that the non-powered fan does not rotate by itself, the power of the drive motor is automatically connected and the non-powered fan is forcibly rotated, so the indoor air can be smoothly ventilated to create a pleasant environment.

Even if the pair of rotors selectively rotating in accordance with the strength and weakness of the wind speed maintains the initial frictional force even when their contact friction surfaces are worn out, no after-care is necessary.
