Description

Damper device using a motor {DAMPER APPARATUS USING A MOTOR}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a damper device, and more particularly, to a damper device that blows air for exhaust in a space such as a toilet, uses a motor (for example, an alternating current motor) and drives the damper.

The damper device is widely used to intake air in a space such as a toilet and exhaust it to the outside.

In one example, the damper device of the toilet is configured to interlock with the light. Therefore, when the user turns on the lamp of the toilet, the damper device operates like a lamp, and the damper device inhales the air inside the toilet and exhausts it to the outside. The damper device stops blowing by stopping the fan driving inside when the light in the toilet is turned off.

In the case of an apartment, the damper device of the toilet is configured to exhaust the intake air through the common pipe via several floors. Apartments are usually equipped with a ventilation system that exhausts the air exhausted from the toilets on the different floors to the outside of the building through common plumbing.

As described above, the damper device provides a function of inhaling air in the toilet and exhausting it to the outside. However, the damper device does not provide a function to effectively block air from the common pipe back into the toilet when the fan is not operated.

For the above reason, the conventional damper device is difficult to effectively prevent the air exhausted from the toilet on the other floor from flowing back into the toilet when the fan is not operated. Therefore, the conventional damper device has a difficulty in keeping the air in the toilet in a comfortable ring state.

It is formed, the exhaust port 14 is formed on the side of the cylinder (18). The housing 10 may be configured to have a short pipe for guiding air exhausted to the exhaust port 14.

The bracket 20 is installed on the upper surface of the housing 10, that is, the upper surface of the cylinder 18. The bracket 20 is used for installation of the AC motor 30 and the drive control module 40.

The AC motor 30 is installed on one surface of the bracket 20 and alternately provides driving force in the forward and reverse directions at each time of supplying power. The AC motor 30 means a motor using commercial AC power.

The blowing motor 80 is installed to drive the fan 70 at the center of the outer wall of the housing 10, that is, the upper surface of the cylinder 18.

The blower motor 80 may be installed to penetrate the upper surface of the cylinder 18 or may be installed on the upper surface of the cylinder 18, and may transmit the driving force by the shaft coupling by the fan 70 and the shaft coupling.

The fan 70 may be installed in the inner space of the housing 10, and may be blown by rotating by the driving force transmitted through the shaft joint from the blower motor 80. More specifically, the fan 70 is preferably installed to intake air from the intake port 12 and exhaust it toward the exhaust port. The fan 70 may use various types of fans capable of laterally exhausting air intake from the bottom, such as a sirocco fan or a blade fan, which may be installed in the inner space of the housing 10.

In the above, the AC motor 30 and the blower motor 80 may be operated in synchronization with the switching operation of the main switch (not shown). To illustrate the case where the main switch is configured to turn on and off the lights in the toilet, the blower motor 80 is also turned on when the main switch is turned on, and the blower motor 80 is also turned off when the main switch is turned off.

The AC motor 30 may be supplied with power at the turn-on time of the blower motor 80, and the AC motor 30 may be operated to provide a forward driving force. In addition, the AC motor 30 may be supplied with power again at the turn-off time of the blower motor 80. In this case, the AC motor 30 may be operated to provide a reverse driving force.

More specifically, the AC motor 30 is operated to provide a forward driving force when the power is supplied in response to the turn-on of the main switch and the blower motor 80, and the power supply in response to the turn-off of the main switch and the blower motor 80. When supplied, it is operated to provide reverse driving force.

As described above, the AC motor 30 changes the driving force in the forward direction and the reverse direction because the AC motor 30 is designed to alternately provide the driving force in the forward direction and the reverse direction every time the power is supplied. And, the circuit for supplying power to the AC motor 30 is preferably configured to supply power to the AC motor 30 in response to the turn on and turn off of the main switch, and those who are unfamiliar with the technical idea of the present invention Since it can be easily carried out, specific examples and explanations thereof will be omitted.

That is, the AC motor 30 provides the driving force in the forward direction when the power is supplied at the first time point, and provides the driving force in the reverse direction when the power is supplied at the second time after the first time point, and at the third time point following the second time point.

On the other hand, the drive control module 40 is installed on the rear surface of the bracket 20, it is configured to alternately provide and release the lowering force in response to the driving force of the AC motor (30). To this end, the drive control module 40 includes a pin 42, a rotating body 44, a rotary lever 46, a first limit switch 48 and a second limit switch 49.

The rotating body 44 receives the driving force from the AC motor 30 by the shaft joint penetrating the bracket 20. The rotating body 44 may be configured in a cylindrical shape and has a pin 42 protruding from the side. The rotating body 44 rotates in the forward direction corresponding to the driving force in the forward direction to rotate the pins 42 from the first position to the second position, and in the reverse direction corresponding to the driving force in the reverse direction, thereby rotating the pins 42 in the second position. Rotate to 1 position

The rotary lever 46 has a predetermined length and one end is connected to the rotating body 44. That is, the AC motor 30, the rotating body 44, and the rotating lever 46 are connected by concentric shafts, and the rotating body 44 and the rotating lever 46 may be rotated in the same direction.

The rotary lever 46 may be configured in various forms according to the intention of the manufacturer, but may be configured as a bar type having a predetermined length as an embodiment of the present invention.

The other end of the rotation lever 46 extending in the longitudinal direction is configured to be in direct or indirect contact with the horizontal bar 62 described later of the drive assembly 60. Accordingly, the rotation lever 46 may transmit a lowering force to the drive assembly 60 in response to the forward rotation of the rotating body 44.

The rotary lever 46 rotates downward in response to the forward rotation of the rotating body 44 to transmit the descending force by pressing the horizontal bar 62 of the drive assembly 60. In addition, the rotation lever 46 rotates upward in response to the reverse rotation of the rotating body 44, thereby releasing the pressing of the horizontal bar 62 of the drive assembly 60, thereby releasing the transmission of the lowering force.

As described above, the other end of the rotation lever 46 may be configured to transmit a lowering force by directly contacting the horizontal bar 62 of the drive assembly 60. Alternatively, the rotary lever 46 may be provided with a ring 46a rotatable at the other end, and may be configured to transmit a lowering force by indirectly contacting through the ring 46a. The ring 46a may be configured on the side of the end of the rotary lever 46. The sides of the ring 46a and the ends of the rotary lever 46 can be joined by pins that penetrate them and ensure rotation. At this time, the diameter of the ring 46a is preferably set larger than the width of the side of the end of the rotary lever 46.

The first limit switch 48 is configured at the first position of the bracket 20, and the second limit switch 49 is configured at the second position of the bracket 20.

Here, the first position may be defined as the position where the rotating body 44 starts the forward rotation, and the second position may be defined as the position where the rotating body 44 starts the reverse rotation.

The first limit switch 48 and the second limit switch 49 each have a contact piece (not shown), and each of the contact pieces is in contact with a tab (not shown) that drives an internal switch (not shown). Configured to operate. The contact of the first limit switch 48 and the second limit switch 49 with the pin 42 means that the rotating pins 42 each contact piece of the first limit switch 48 and the second limit switch 49. It can be understood to push the contact to the tang, detailed illustration and description thereof will be omitted.

By the above-described configuration, the first limit switch 48 and the second limit switch 49 operate when they are in contact with the rotating pin 42, and the first limit switch 48 and the second limit switch 49 are operated. In operation, driving of the AC motor 30 may be stopped by supplying power to the AC motor 30.

The circuit structure between the first limit switch 48, the second limit switch 49, and the AC motor 30 for controlling the AC motor 30 may be easily implemented by those skilled in the art. Detailed examples and descriptions are omitted.

On the other hand, the damper 50 has an area covering the inlet 12 and may be of a flat plate type disposed below the inlet 12. The damper 50 may have a shape corresponding to the inlet 12, and exemplarily includes a circular plate as an embodiment.

Embodiment of the present invention may be provided with a packing member to improve the airtight state by the packing of the damper 50 and the inlet 12.

The packing member may be configured for packing in at least one of an outer periphery of the inlet 12 facing the damper 50 and an edge region of the damper 50 facing the outer periphery of the inlet 12.

An embodiment of the present invention illustrates that the packing ring 52 is configured as a packing member at the edge of the damper 50. Here, the packing ring 52 wraps around the edge of the damper 50 and, when the damper 50 is raised, abuts against the outer periphery of the inlet 12 so that the inner space of the housing 10 and the lower portion of the damper 50 are closed. It can be configured to pack between spaces.

Meanwhile, the drive assembly 60 includes a horizontal bar 62, rods 64, guiders 66, and a coil spring 68.

In the drive assembly 60, the horizontal bar 62 receives the downward force through the rotation lever 46 of the drive control module 40. More specifically, the horizontal bar 62 is configured to have a width corresponding to the thickness of the ring 46a configured at the end of the rotary lever 46, has a spaced interval on the upper side of the blower motor 80, and has a cylindrical ( It may be arranged to correspond to the diameter of 12). At this time, the horizontal bar 62 is preferably configured to be spaced apart from the blower motor 80 so as not to hit the blower motor 80 when lowered by the lowering force.

The pair of rods 64 extends downward from both ends of the horizontal bar 62, and can be moved up and down along the wall of the housing, that is, the cylinder 18, and the damper 50 is connected to the extended end. The pair of rods 64 may be coupled to the damper 50 by various methods such as screw defects or welding, and may be coupled using an auxiliary assembly (not shown) to keep the damper 50 horizontal. .

In addition, the pair of guiders 66 respectively form channels in the outer walls of the housings, ie, the cylinders 18 in opposite directions, and the rods 64 are disposed in the channels to guide the lifting and lowering of the rods 64 as channels. It is composed. Each guider 66 is preferably configured to have the same height as the cylinder 18.

And the coil spring 68 is comprised by the pair of rod 64, respectively. Here, the coil spring 68 is located between the guider 66 and the horizontal bar 62 and is installed to wind the rod 64.

With the above configuration, when the horizontal bar 62 and the pair of rods 64 are lowered by the lowering force, the damper 50 coupled to the pair of rods 64 is lowered. On the contrary, when the lowering force is released, the horizontal bar 62 and the pair of rods 64 are elevated by the restoring force of the pair of coil springs 68, and as a result, the damper 50 is elevated.

The operation of the damper device according to the embodiment of the present invention configured as shown in FIGS. 1 to 3 will be described with reference to FIGS. 4 to 9.

First, a state in which the inlet 12 is closed by the damper 50 may be described with reference to FIGS. 4 to 6.

4 to 6 correspond to a state in which a main switch (not shown) is turned off. In the state where the main switch is turned off, the song * j motor 80 and the alternating current motor 30 are also turned off. The fan 80 is not driven by the turn-off of the blower motor 80.

4 to 6, the rotary lever 46 pivoted through the AC motor 30 and the rotating body 44 is lifted by releasing the lowering force, for example, parallel to the horizontal bar 62. Maintain state. In addition, the pin 42 provided in the rotating body 44 is in contact with the first limit switch 48.

4 to 6, the horizontal bar 62 is held up by the elastic force of the coil spring 68 and coupled to the ends of the pair of rods 64 connected to the horizontal bar 62. The damper 50 is raised like the horizontal bar 62.

That is, in FIGS. 4 to 6, the damper 50 is in close contact with the outer main surface of the inlet 12 to maintain the airtightness of the inlet 12. The airtightness of the damper 50 and the inlet 12 can be firmly held by the packing ring 52. As a result, outside air introduced through the exhaust port 14 is blocked from entering the space below the damper 50 through the inlet 12.

In the state of Figs. 4 to 6, when the user turns on the light to use the toilet, the main switch is turned on. The blower motor 80 is driven by being supplied with power in conjunction with the turn-on of the main switch, and the AC motor 30 is also driven by being supplied with power.

The fan 70 starts blowing while the blowing motor 80 starts to drive while rotating in one direction.

In addition, the AC motor 30 provides a forward driving force when the power is supplied.

When the AC motor 30 provides the forward driving force, the rotor 44, the pin 42 and the rotary lever 46 start forward rotation as shown by arrow A1.

The pin 42 rotates from the first position of the first limit switch 48 to the second position where the second limit switch 49 is located by the forward rotation of the rotating body 44.

And the rotation lever 46 descends in the direction of arrow A1 by a forward rotation, and the horizontal bar 62 pressed by the ring 46a of the edge part of the rotation lever 46 descends in the direction of arrow A2.

When the horizontal bar 62 descends as described above, the pair of rods 64 and the dampers 50 descend in the direction of the arrow A2.

The forward drive of the AC motor 30, the forward rotation of the rotary lever 46 and the lowering of the rod 64 and the damper 50 are in the second position where the pin 42 is in contact with the second limit switch 49. It stays until it is reached.

When the pin 42 contacts the second limit switch 49 by the rotation of the rotating body 44, the second limit switch 49 operates to stop the drive of the AC motor 30.

By stopping the drive of the AC motor 30 described above, the forward rotation of the rotary lever 46 and the lowering of the rod 64 and the damper 50 are stopped.

As a result, the damper 50 is opened by the forward driving of the AC motor 30. In this case, an open state of the damper 50 may be described with reference to FIGS. 7 to 9.

7 to 9 correspond to a state where the main switch is turned on as described above. In the state where the main switch is turned on, the song * j motor 80 is being driven and the AC motor 30 is turned off by the operation of the second limit switch 49. Therefore, in the state in which the damper 50 is opened, the fan 80 intakes air from the intake port 12 by driving the blower motor 80 and blows the air to the exhaust port 14.

7 to 9, the rotation lever 46 pivoted through the AC motor 30 and the rotating body 44 is in a state in which the lowering force is lowered, for example, an acute angle with the horizontal bar 62. Keep crossing at right angles. In addition, the pin 42 provided on the rotating body 44 is in contact with the second limit switch 48.

7 to 9, the horizontal bar 62 remains lowered by the lowering force of the rotation lever 46 and is coupled to the ends of the pair of rods 64 connected to the horizontal bar 62. The damper 50 is lowered like the horizontal bar 62.

7 to 9, when the user turns off the light after using the toilet, the main switch is turned off. The blower motor 80 stops driving in conjunction with the turn-off of the main switch. Therefore, the fan 70 stops driving.

When the main switch is turned off, the AC motor 30 is supplied with power. At this time, the AC motor 30 provides a reverse driving force by providing power.

When the AC motor 30 provides the reverse driving force, the rotating body 44, the pin 42 and the rotating lever 46 start the reverse rotation as shown by arrow B1.

The pin 42 rotates from the second position of the second limit switch 49 to the first position where the first limit switch 48 is located by the reverse rotation of the rotating body 44.

And the rotation lever 46 rises in the direction of arrow B1 by reverse rotation, and the horizontal bar 62 pressed by the ring 46a of the edge part of the rotation lever 46 rises in the direction of arrow B2.

When the lowering force is released by the reverse rotation of the rotary lever 46 as described above, the horizontal bar 62 is raised, the pair of rods 64 and the damper 50 is raised in the direction of the arrow A2.

The reverse drive of the AC motor 30, the reverse rotation of the rotary lever 46, and the rise of the rod 64 and the damper 50 are performed at the first position where the pin 42 is in contact with the first limit switch 48. It stays until it is reached.

When the pin 42 contacts the first limit switch 48 by the rotation of the rotating body 44, the first limit switch 48 operates to stop the drive of the AC motor 30.

By stopping the drive of the AC motor 30 described above, the reverse rotation of the rotary lever 46 and the rise of the rod 64 and the damper 50 are stopped.

As a result, the damper 50 is closed by the reverse driving of the AC motor 30 described above. In this case, since the damper 50 is closed as in FIGS. 4 to 6, duplicate description thereof will be omitted.

According to the present invention, the flat damper may be driven to move up and down by using an AC motor, and when the fan 70 does not blow, the lifted flat damper is in close contact with the intake port so that the outside air is returned to the internal space. You can block inflows.

In addition, the present invention can effectively drive the flat damper by driving the flat damper by using the AC motor and the limit switches for controlling the drive of the AC motor to alternately provide the driving force in the forward and reverse directions for each power supply.

In addition, the damper device is configured such that the flat damper is driven by the driving force of the AC motor and the restoring force of the coil spring, thereby driving the flat damper with a simple structure.
