Description

Flanged Shutters {FLANGE TYPE SHUTTER}

The present invention relates to a flange-type shutter installed between the exhaust device and the exhaust pipe and the exhaust pipe that needs to be ventilated to exhaust the odor generated in the kitchen or toilet and to prevent the odor flow back to the kitchen or toilet through the exhaust pipe In particular, the present invention relates to a flange-type shutter which facilitates connection of the exhaust device and the exhaust pipe by a flange formed at one end of the shutter body and a protrusion formed at the other end.

Conventionally used shutters are installed in places requiring ventilation, such as kitchens, toilets, heat exchangers, etc., to allow the air, odors, etc., which are contaminated from the inside to the outside, to be well discharged to the outside, while the inside (from outside) It serves to block the inflow of air or odor contaminated by the air from outside to indoor).

To this end, a disc-shaped blocking plate is installed inside the shutter to open and close the flow path at a desired angle. When the blocking plate is rotated at a right angle to the flow path, the flow path is blocked to prevent the inflow of fluid from the outside or the blocking plate is parallel to the flow path. When rotated properly, the flow path is opened to facilitate the discharge of the fluid from the inside to the outside.

In this way, the shutter to open and close the flow path to discharge the odor to the outside and prevent the odor from flowing back inside may be installed in the exhaust line or installed in the total heat exchanger.

The shutter has an annular protrusion formed on the outer circumferential surface so that a flexible tube such as a bellows is coupled to one side of the body, and an extension portion having a larger diameter than the annular protrusion side is formed on the other side to discharge contaminated air or odor. The discharge connection pipe connected to the discharge device such as the lead-in connection.

However, since the discharge connector connected to the discharge device such as the range hood is inserted into the extension part formed on one side of the shutter and combined, the shutter is separated to separate the shutter and the discharge connector of the ventilation discharge device for the replacement or repair of the shutter. Since it was necessary to release the fitting coupling with the discharge connector by moving the discharge connector and the separation of the shutter was very inconvenient and there was a problem that the work time is considerably required.

8 and 9, the final gear shaft 6 which rotationally drives the rotation shaft 4 of the blocking plate 2 which opens and closes the shutter 1 is generally connected by a coupling 5. The rotation shaft 4 and the gear shaft 6 are connected. For example, when the motor shaft 8 rotated by the rotation of the motor 7 is rotated, the worm gear coupled to the motor shaft 8 has a predetermined speed through a gear train 9 composed of a plurality of pinion gears. The deceleration of the furnace is carried out, and the rotation shaft 4 of the blocking plate 2 to which the gear shaft 6 of the final reduction gear connected finally among the gear train 9 is connected by the coupling 5 is at a predetermined angle (at a right angle). ) Repeat the forward and reverse rotation.

Herein, the motor 7 may be a DC motor or an AC motor.

Reference numeral 10 denotes a substrate (PCB) on which a motor, a gear train 9, etc. are installed, reference numeral 11 denotes a base cover that protects the substrate 10, and reference numeral 12 denotes a base cover by a shutter (1). Bracket for installation on The base cover 12 and the substrate 10 may be protected by a lid (not shown) to prevent foreign substances such as dust from penetrating into the substrate 10.

Therefore, as the blocking plate 2 is repeatedly driven by the motor 7 in a predetermined angle range, play is generated in the coupling 5 to which the rotation shaft 4 is coupled. The coupling 5 is coupled to the gear shaft 6, and a pressing portion (not shown) is formed at right angles to the longitudinal direction of the coupling 5. This pressing part comes in contact with a limit switch (not shown) installed on the substrate 10 as the coupling 5 rotates when the gear shaft 6 is rotated by the rotation of the motor shaft 8. ) Is repeatedly rotated at a predetermined angle, for example at right angles.

However, play is generated in the coupling 5 which is repeatedly rotated of the coupling 5 by the rotation of the motor shaft 8, and the play is gradually accumulated so that the blocking plate 2 does not rotate exactly at an angle of 90 degrees. Therefore, the blocking plate 2 is not rotated correctly vertically or horizontally to the flow path of the shutter 1. Therefore, a problem arises in that the opening and closing of the flow path of the shutter 1 is not made accurately by repeated forward and reverse rotation of the blocking plate 2.

As described above, when the rotating shaft 4 of the blocking plate 2 is not directly connected to the final gear shaft 6 of the gear train 9, but is directly coupled to the shaft of the motor (not shown). Edo coupling caused a problem that the rotational axis of the blocking plate was not repeatedly rotated at a predetermined angle.

In addition, the soft plate 3 coupled to the circumference of the barrier plate 2 and above and below the circumference of the barrier plate 2 causes the coupling force to be lowered by repeated rotation of the barrier plate 2 so that the durability of the flexible plate 3 is reduced. There was a problem of this deterioration.

The present invention was developed to improve the above-mentioned conventional problems, the object of the present invention is to improve the body structure of the shutter and the installation of the discharge device and the shutter or the connection pipe of the discharge device and the shutter assembly and installation work made easy To provide a shutter.

Another object of the present invention is to provide a flange-type shutter in which the blocking plate of the shutter is repeatedly rotated at the correct angle.

The present invention is achieved by forming a flange on one side of the shutter body and forming an annular protrusion on the other side so that one side can be connected to the connection pipe of the discharge device and the other side can be connected to the flexible pipe.

The present invention is achieved by forming the motor-driven shutter plate rotating shaft as the final gear shaft of the motor shaft or the reducer so that the rotating angle of the shutter plate is always kept constant.

The flange-type shutter of the present invention can be connected to the flange instead of the fitting by the flange formed on one side of the shutter body to simplify the assembly and disassembly work as well as to significantly reduce the work time required.

In addition, since the rotating shaft of the shutter plate is integrally formed with the motor shaft or the final gear shaft driven by the motor, the rotating angle of the shutter plate is always kept constant.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

In the flanged shutter of the present invention, a blocking plate is installed to be rotated in the shutter body to block a flow path in the shutter body, a flexible plate of an elastic material is coupled around the blocking plate, and a motor is coupled to rotate the blocking plate forward and reverse. In the shutter,

A flange is formed on one side of the shutter body and an annular protrusion is formed on the other side so that one side is connected to the flange and the other side is connected to the flexible tube.

In addition, the blocking plate is coupled to the motor shaft to be supported and driven to rotate in the shutter body and the other side is supported by the idling shaft to be supported by the shutter body,

The blocking plate has a plurality of through-holes formed around the blocking plate so that the flexible plate coupled to the upper and lower sides of the blocking plate is integrally connected.

The soft plate is characterized in that the extension portion is further formed, but more integrally connected through the through hole of the blocking plate.

Flange type shutter of the present invention is a flange 101 formed on one side of the cylindrical shutter body 100 through the through hole 103 of the connection pipe (T2) connected to the discharge device (not shown) (101) Can be easily assembled and connected, by fitting the flexible pipe (T2) such as corrugated pipe to the annular projection (102) formed on the other side can be simply connected to the exhaust port side.

The flange-type shutter of the present invention having the flange 101 formed thereon is installed at right angles to the air flow path inside the cylindrical shutter body 100 so as to block the air flow path of the shutter by repeating opening and closing operation. ) Is installed inside the shutter body 100. The blocking plate 110 has a plurality of through-holes 111 are spaced apart at regular intervals so as to be adjacent to the blocking plate 110 so that the soft plate 120 of the rubber material is connected to the upper, lower integral. The soft plate 120 made of rubber is formed to further extend in the radial direction while enclosing a portion of the upper and lower circumferences of the blocking plate 110, and the extension 121 is formed with the blocking plate 110. It serves to ensure contact with the inner peripheral surface of the shutter to ensure that the gap between the inner peripheral surface of the shutter body 100 is elastically sealed.

In addition, through the plurality of through holes 111 formed around the blocking plate 110, the flexible plate 120 surrounding the upper and lower surfaces of the blocking plate 110, the upper and lower soft plates are further connected to each other integrally to the blocking plate ( By the repeated opening and closing operation of 110, the soft plate 120 is not easily separated from the blocking plate (110).

In addition, the blocking plate 110 is provided with a rotating shaft 112-1, which is configured as the final gear shaft of the reduction gear driven by the motor 150, on one side of the blocking plate 110, and rotates the blocking plate 110. The idle shaft 112-2 is completely separated from the pivot shaft 112-1 so as to be supported, and is installed on the other side of the pivot shaft 112-1. Reference numeral 112 is a through hole for fixing the blocking plate 110 to the rotation shaft 112-1 and the idle shaft 112-2, respectively.

The rotating shaft 112-1 and the idle shaft 112-2 are preferably configured in a semicircular shape so that the assembly with the blocking plate 110 can be easily performed. Reference numeral 132 is a screw hole for fixing the rotating shaft 112-1 and the idle shaft 112-2 to the blocking plate 110 with a screw (S).

Here, the rotation shaft 112-1 is directly driven according to the rotation of the motor shaft when power is applied to the motor 150, and the idle shaft 112-2 is not directly connected to the motor shaft, but the blocking plate 110 is used. ) Is held in the shutter and the other side of the blocking plate 110 is supported so that the blocking plate 110 can be correctly and reversely rotated in the shutter body 100 when the rotating shaft 112-1 rotates. do. Reference numeral 131 denotes a bracket for mounting the shutter driver including the motor to the body 100, reference numeral 130-2 denotes a lower cover for connecting the shutter driver to the bracket 140, and reference numeral 130- 1 is an upper cover of the shutter driver.

The shutter of the present invention configured as described above has the rotational axis and the idling axis of the blocking plate 110 in the perpendicular direction when the blocking plate 110 is exactly horizontally in the flow path in the shutter body 100, as in the conventional blocking plate. Installed in the (100) is rotated in the forward and reverse direction, the rotation shaft is the final reduction gear shaft driven by the motor 150.

Therefore, when power is applied to the motor 150, the rotation shaft 112-1 is directly and reversely made by the motor shaft, and the blocking plate 110 to which the rotation shaft 112-1 is coupled is also positive, The reverse rotation is made so that the flow path of the surfer is opened or closed.

A limit switch 170 is installed on the rotational shaft 112-1, which is the final reduction gear shaft driven by the motor 150, at a desired angle on the substrate 140 to control the rotational angle, and is provided on the rotational shaft 112-1. The stopper 171 is installed between the rotational shaft 112-1 and the limit switch 170 to prevent the combined pusher 161 from being over contacted beyond the angle range of the limit switch 170. The pressing portion 161 may be coupled to the rotation shaft in a conventional coupling manner, and for example, a coupling hole having an axial engagement hole formed at the rear end side of the pressing portion that is not in contact with the limit switch is connected to the rotation shaft 112-1. It can be fixed by being screwed together after being fitted.

When the blocking plate 110 is rotated forward and backward, the extension part 121 of the flexible plate 120 installed around the blocking plate 110 elastically contacts the inner circumferential surface of the shutter body 100 to ensure blocking of the flow path of the shutter. Can be done. In addition, the soft plate 120 repeatedly contacting and releasing with the inner circumferential surface of the flow path of the shutter by repeated forward and reverse rotation of the blocking plate 110 is blocked through the through hole 111 formed around the blocking plate 110. The upper and lower portions of the plate 110 are further connected to each other so that the flexible plate 120 is not easily separated from or ruptured even when the soft plate 120 is repeatedly bent or compressed.

In addition, since the extension part 121 of the flexible plate 120 is made of an elastic material, the contact with the inside of the shutter is made elastic, so that the flow path inside the shutter is more surely sealed.

In the flange type shutter of the present invention, the rotation shaft 112-1 for rotating the blocking plate 110 is integrally formed with the final gear shaft of the gear train 160 driven by the motor 150, thereby blocking The angle at which the plate 110 is repeatedly rotated is not changed but is constantly rotated, for example, at an angle of 90 degrees.

Therefore, when the power is applied to the motor 150, as the forward and reverse rotation of the rotation shaft 112-1 is performed by the motor shaft, the other side of the blocking plate 110 to which the rotation shaft 112-1 is fixed is also the idle shaft. It is supported by the body (100) by (112-2), so that the forward and reverse rotation, the flow path of the shutter is selectively opened or closed by the blocking plate (110).

In the forward and reverse rotation of the blocking plate 110, the extension part 121 of the soft plate 120 provided around the blocking plate 110 elastically contacts the inner circumferential surface of the shutter body 100, so that the passage of the shutter is surely blocked. Can be done. In addition, the soft plate 120 repeatedly contacting and releasing with the passage circumferential surface of the shutter by repeated forward and reverse rotation of the blocking plate 110 is blocked through the through hole 111 formed around the blocking plate 110. Since the upper and lower portions 122 and 123 of the plate 110 are integrally connected to each other, the flexible plate 120 may not be easily peeled off or ruptured even when the flexible plate 120 is repeatedly bent or compressed.

In addition, since the extension part 121 of the flexible plate 120 is made of an elastic material, contact with the inside of the shutter is made elastic, so that the flow path inside the shutter is surely sealed.
