FIG. 3 is a perspective view of a ceiling-mounted type ventilator according to an embodiment of the present invention, and FIG. 4 is an exploded perspective view of a ceiling-mounted type ventilator according to an embodiment of the present invention.

The ceiling-mounted type ventilator 1000 according to an embodiment of the present invention is lowered together with the driving of the fan and is raised when the fan is stopped and opened or closed according to whether the fan is driven. Thus, a single cover can be used, 3 and 4, a casing 100, a guide casing 200, a suction unit 300, a front cover 400, and an opening / closing unit (not shown) 500).

The casing 100 is installed in a ceiling panel C (see FIG. 7). The casing 100 is embedded in a bathroom ceiling to discharge air including moisture, soap odor, odor, etc. generated in the bathroom. The casing (100) includes a main body (110) and a flange (120). The main body 110 has a structure in which a structure of a guide casing 200 and a suction portion 300 to be described later is mounted. The main body 110 is opened at its lower surface to form a suction port (not shown in the figure) A discharge port 130 is formed. A duct (D) communicating with the outside may be connected to the discharge port (130), and the duct (D) may be provided with a bellows. A flange 120 is formed on the lower edge of the main body 110 along the horizontal direction. The upper surface of the flange 120 abuts the lower surface of the ceiling panel C and is fastened to the ceiling panel C by a fastening member such as a screw.

The guide casing 200 guides indoor air sucked by the suction unit 300 to the discharge port 130 side. The guide casing 200 is a housing in which the suction unit 300 is accommodated. The guide suction hole 210 is formed on the lower surface of the guide casing 200. The guide discharge hole 220 is formed on one side wall. The indoor air is introduced into the guide casing 200 by the suction unit 300 and then discharged to the discharge port 130 through the guide discharge hole 220.

The suction unit 300 includes a first motor 310 and a sirocco fan 320 for exhausting indoor air to the outside. The first motor 310 is installed inside the guide casing 200 and a sirocco fan 320 is installed in the motor shaft of the first motor 310 as a centrifugal fan. By installing the sirocco fan 320, it is possible to efficiently discharge the indoor air while the noise is small.

Since the casing 100, the guide casing 200, and the sirocco fan 320 are constituted by a general ventilator, detailed description thereof will be omitted.

FIG. 5 is a bottom perspective view of a front cover of a ceiling-mounted type ventilator according to an embodiment of the present invention, and FIG. 6 is a view of an opening and closing part of a ceiling-mounted ventilator according to an embodiment of the present invention.

The front cover 400 has a substantially plate-like shape and finishes the lower surface of the casing 100. The front cover 400 is fastened to the flange 120 through fastening means such as screws. The front cover 400 is formed with a through hole 410 for air inflow. The through-hole 410 is passed through the front cover 400 in the thickness direction. A groove 420 is formed in the front cover 400 along the circumference of the through hole 410. The groove portion 420 has a configuration in which the wings of the opening and closing part 500 are closely attached. The groove portion 420 may be formed continuously along the periphery of the through hole 410. Details will be described later.

In this embodiment, the opening / closing part 500 is mounted on the front cover 400. The opening and closing part 500 includes a body part 510 disposed at the through hole 410 and a blade 520 formed at the lower end of the body part 510. As will be described later, the body 510 is preferably raised or lowered in the through hole 410 and the casing 100, and is preferably smaller than the through hole 410 so as to be easily raised and lowered. Further, a plurality of suction holes 511 may be formed on the sidewall of the body portion 510.

2), a grill is formed on the first cover 21 which closes the lower surface of the housing, and the second cover 22 is provided with a gap between the grill and the first cover 21, (21). Accordingly, the second cover 22 prevents the grill from being seen from the outside, and prevents the dust or the like falling from the inside of the casing 100 or the grill from falling to the floor of the room. When the fan is driven, the room air is sucked through the gap between the first cover 21 and the second cover 22 and flows into the housing through the grille. At this time, a gap is always formed between the first cover 21 and the second cover 22. That is, since the grill can not be completely shielded in order to allow air to flow through the grill, the second cover 22 is mounted on the first cover 21 with the gap between the first cover 21 and the first cover 21. Since the gap is always maintained, the inflowed air or the air exhausted from another home or another space can be adversely introduced into the room through the gap. As an example, the smell of a cigarette in the bathroom of another home can be introduced into the room through the duct D. In order to prevent this, an electric damper 23 must be installed in the conventional ceiling-mounted type ventilator.

However, the present embodiment has only a single front cover 400, not two covers. At this time, the penetrating part 410 formed on the front cover 400 is to be shielded. This is because the opening and closing part 500 is disposed on the through hole 410, not on a separate cover. The body 510 is smaller than the through hole 410 so that a gap is formed between the body 510 and the front cover 400 and air is sucked through the gap and the suction hole 511. At this time, external air can be introduced into the room by the gap. However, a groove 420 is formed in the front cover 400, and the wing 520 is closely attached to the groove 420, It can be completely shielded. That is, when the opening / closing part 500 is closed, the entire body part 510 is disposed inside the through hole 410 and the wing 520 is closely attached to the groove part 420 to completely block the through hole 410, 500 are opened, the body 510 is lowered and the wing 520 is separated from the groove 420. The room air is discharged by the gap between the body 510 and the front cover 400 formed at this time.

A second motor (not shown) is mounted in the casing 100, and the opening / closing part 500 is coupled to the second motor through a crank (not shown) to be able to move up and down. At this time, a speed reducer may be mounted on the second motor. That is, the opening / closing part 500 is provided so as to be movable up and down along the thickness direction of the front cover 400 through the crank. When the user presses the switch to start the ventilation (when the first motor 310 is driven and the sirocco fan 320 rotates), the second motor is driven and the motor shaft is rotated forward to lower the opening / closing part 500. Normally, the opening / closing part 500 completely closes the through hole 410. In this case, since air in the room can not be exhausted, the through hole 410 should not be shielded when the sirocco fan 320 is driven. Thus, the second motor is rotated in the forward direction when the first motor 310 is driven. The opening / closing part 500 is separated from the front cover 400 by descending through the crank, and the room air is separated from the opening / closing part 500 and the front cover 400, and is discharged to the discharge port 130. (See Fig. 8)

When the user depresses the switch again to terminate the ventilation, that is, when the first motor 310 is stopped and the sirocco fan 320 is stopped, the motor shaft of the second motor rotates reversely and the opening / closing part 500 ascends. That is, the opening / closing part 500 rises through the crank and is disposed in the through hole 410, and the through hole 420 is completely shielded by the blade 520 being in close contact with the groove part 420.

On the other hand, the reverse rotation of the motor shaft of the second motor can be realized by the charging section. The charging unit stores energy when the first motor 310 and the second motor are supplied with power, and when the first motor 310 is stopped because the power supply is interrupted, So that the through hole 420 is shielded by reversing the axis.

The opening / closing part 500 is provided so as not to protrude from the front cover 400. Specifically, the blade 520 of the opening / closing part 500 is provided below the depth of the groove 420 so that when the opening and closing part 500 completely shields the through hole 410, the opening and closing part 500 is separated from the front cover 400 So as to have a clean appearance, and a phenomenon in which the ceiling is seen to be low does not occur.

Meanwhile, the lamp unit 600 may be mounted on the opening and closing unit 500. The lamp unit 600 is supplied with power when the first motor 310 is driven and can be cut off when the first motor 310 is stopped. That is, only when the sirocco fan 320 is driven, power is supplied to the lamp to perform a function such as taillight and mood. The lamp unit 600 is mounted on the side wall of the opening / closing unit 500, and more specifically, directly mounted on the blade 520. Therefore, the light irradiated from the lamp 610 is not irradiated directly to the room but is indirectly illuminated after being impinged upon the blades 520 or irradiated after colliding with the front cover 400 or the like, And so on.

The operation of the ceiling-mounted type ventilator according to one embodiment of the present invention will now be described. For convenience, the ceiling-mounted type ventilator will be described as being driven and stopped.

FIGS. 7 and 8 are explanatory views of the operation of a ceiling-mounted type ventilator according to an embodiment of the present invention.

When the fan is driven

When the user presses the switch, this signal is applied to the first motor 310 and the second motor (not shown), and power is supplied to the lamp unit 600.

The motor shaft of the second motor rotates in a normal direction and the opening and closing part 500 descends through a crank (not shown) so that the wing 520 is separated from the groove part 420 and the opening / closing part 500, the front cover 400, (100). At the same time as the second motor is rotated, the first motor 310 is driven to rotate the sirocco fan 320, and the air in the room is sucked through the gap between the opening and closing part 500 and the front cover 400, 200). The air introduced into the guide casing 200 is guided by the guide discharge hole by the shape of the guide casing 200 and discharged through the discharge hole.

On the other hand, the light emitted from the lamp 610 impinges on the blades 520 and then is irradiated to the outside to be indirectly illuminated, thereby resulting in a mood and a mood that produces an atmosphere of antiquity.

When the ventilator stops

When the user again presses the switch, this signal is applied to the first motor 310 and the second motor, and the power supply to the lamp unit 600 is interrupted.

The first motor 310 is stopped and the sirocco fan 320 is stopped. In addition, the energy charged in the charger is supplied to the second motor, and the motor shaft of the second motor rotates in the reverse direction, and the opening / closing part 500 rises through the crank to completely block the through hole 410. The through hole 410 is completely shielded, thereby preventing the outside air from flowing into the room through the duct D.

Therefore, according to the present invention, when the fan is lowered while the fan is stopped and the fan is stopped, the fan can be opened and closed according to whether the fan is driven or not. Thus, a single cover can be used, and the appearance is good and noise is small. A flush ventilator is provided.
