Description

  The present invention relates to a remote control opening / closing device for a drain plug that opens and closes a drain of a water tank such as a basin and a bathtub.

A conventional remote control opening / closing device for a drain plug has a drain plug based on an operation transmitted from an operation unit disposed at a position separated from the drain port to a drive unit positioned at the drain port via a release wire. It was moved up and down to open and close the drain.
However, the remote-operated opening / closing device for the drain plug is designed to pass the release wire through the drain pipe, and thus is complicated in terms of the structure generated and the sealing performance.
In addition, because of the barrier-free relationship of the building of the house, the distance between the bottom of the bathtub and the floor is narrowed, the drain trap is lowered, the release wire passing through the drain pipe is sharply bent, and sliding with the drain valve opening and closing operation The resistance was so great that it made the sliding worse, causing problems and inconvenient.

Therefore, a remote operation opening / closing device that does not allow the release wire to pass through the drain pipe has been considered.
This remote control opening / closing device for the drain plug is operated by a solenoid disposed in the drain pipe for raising and lowering the drain plug for opening and closing the drain port.
The solenoid provided in the drain pipe operates to suck and return the plunger by electromagnetic force, and lifts and lowers the drain plug having a shaft rod connected to the plunger, thereby opening and closing the drain port.
Even so, the electromagnetic force of the solenoid that causes the plunger to perform the suction operation and the return operation must depend on the electric power from the electric wire from the outside of the drain pipe. (Patent Document 1)

Therefore, in order to solve the above, there are the following as a remote control opening / closing device for a drain plug that can be operated without passing a release wire or an electric wire through the drain pipe.
The drain plug that opens and closes the drain port of this apparatus is fixedly provided with a follower magnet for the shaft rod portion, and a drive magnet is disposed outside the drain pipe, and the drive magnet is connected to the drain pipe. When moved up and down along the outer peripheral surface, the driven magnet is moved up and down following this movement. The drain plug provided with this follower magnet moves up and down in the drain pipe without using a release wire and opens and closes the drain port. (Patent Document 2, Patent Document 3)

  By the way, the remote control opening / closing device of the drain plug in which the solenoid is disposed in the drain pipe has to wire the electric wire to the solenoid in the drain pipe. The construction and the construction work were made difficult by the fact that the construction was complicated and electrical work was required.

  In addition, it is assumed that no electric wire is wired in the drain pipe, and a follower magnet is fixed to the drain pipe, and a drain plug with a driving magnet that moves up and down along the outer peripheral surface of the drain pipe is provided. There is an operation switchgear. However, although this device does not require wiring work to the inside of the drain pipe, it is necessary to carry out the construction of transmission members such as wire wiring and release wire for remote control from the remote control unit to the drain port, The construction is difficult and the structure is complicated.

  This remote-operated opening / closing device for the drain plug is such that the drive magnet moving up and down along the outer peripheral surface of the drain pipe causes the driven magnet in the drain pipe to follow and the drain plug connected thereto is raised and lowered. However, due to the magnetic force of the follower magnet that follows, it is magnetized in the drain and the drain pipe, making it easy for dirt to adhere, slowing up and down the drain plug, and hindering the opening and closing of the drain Became.

A plug opening and closing drive shaft for opening and closing the drain outlet is installed.

  The stopper opening / closing drive shaft that slides in the axial direction to open and close the drain opening is provided with a shock absorber spring that absorbs the impact in the axial direction.

  Further, the remote control opening / closing device for the drain plug is mounted via a support member that is supported and fixed to the drain fitting of the drain port, so that it can be arbitrarily replaced and can be retrofitted.

  In addition, although opening / closing of a drain outlet is generally implemented by raising / lowering a drain plug, it is not limited to it, You may slide horizontally.

  The remote control opening / closing device of the drain plug according to the present invention transmits the remote operation by wireless in the operation unit to the drain plug, so that the release wire and the electric wire required for the remote operation are not required, and its arrangement and wiring Since there is no structure for the construction, the entire structure is simplified, and the construction work can be done easily and easily.

  In addition, since the drive unit, power supply, and control unit installed in the drain plug are embedded and sealed in the drain plug consisting of the main body case and the plug cover, the drain plug is structurally excellent in sealing performance. The lifting function is also good. Moreover, there is no difficulty in burying.

  And since the drain plug is equipped with the shock absorber which absorbs the impact of an axial direction, even if there is a stepping-on impact to a drain plug, there is no problem and it does not cause trouble.

  In addition, the remote control opening / closing device for the drain plug of the present invention can simply attach the drain plug equipped with the drive unit, the power source, and the control unit to the drain fitting of the drain port. It can be done without hesitation.

The rotation of the motor (drive unit) 3 is transmitted to the shaft bar portion 2 via the speed reduction mechanism 5, and the rotation transmission shaft 21 that raises and lowers the drain plug A by rotating and the support member C are fitted. A plug opening / closing drive shaft 22 that slides in the axial direction to open and close the drain port is configured.
The plug opening / closing drive shaft 22 is provided with a closing sensor 116 at the upper limit point of the sliding and an opening sensor 115 at the lower limit point. When the closing sensor 116 is turned on, the drain opening is closed. The raising and lowering of the drain plug is stopped, and the raising and lowering of the drain plug is stopped in a state where the drain port is opened by the switch ON of the open sensor 115.

  The speed reduction mechanism 5 may be a worm / worm gear mechanism that transmits the rotation of the motor (drive unit) 3 to the worm and worm gear, and the rotation transmission shaft 21 is rotated to move the drain plug A up and down. The sun gear 51 by the motor (driving unit) 3 rotates the planetary gear 53 with the ring gear 52 that is a rotation control gear, rotates the carrier 54 together, and the rotation transmission shaft 21 rotates. A planetary gear mechanism that raises and lowers A may be used.

By the way, as shown in FIGS. 3 and 4, the remote operation opening / closing device has a control unit 5 for controlling the raising / lowering operation of the drain plug only in the ON / OFF switch of the drain plug opening / closing display in the operation section to be remotely operated. First, the receiver 7, the motor (driving unit) 3 that operates the raising and lowering of the drain plug, the battery (power source) 4, the speed reduction mechanism 5, etc. may all be embedded in the drain plug A.

The control of the control unit 6 will be described with reference to FIG. 5. An open button 112 for displaying opening / closing of the drain port and a close button 113 are displayed by the transmitting unit 111 provided in the operation unit disposed at a position separated from the drain port. The operation of the ON-OFF switch is transmitted to the drain plug wirelessly.
This is received by the receiving unit 114 embedded in the drain plug, and the control unit 6 determines 115 whether the drain valve is open or closed correctly from the raised / lowered position of the drain plug. ) 3 is rotated forward and backward.
As a result, the upper and lower limits of the drainage plug that is moved up and down are detected by the open sensor 116 and the closed sensor 117 as being ON when the drain plug is on, and the motor (drive unit) 3 rotates. Is stopped 120, and the raising and lowering of the drain plug is stopped. When the position of the open sensor 116 and the closed sensor 117 is not detected and the open sensor 116 is in the OFF state, the drain plug is raised by the normal rotation 118 of the motor, and the drain port is opened. When the closing sensor 117 is OFF, the drain plug is lowered by the motor reversal 119 and the drain outlet is closed. Then, when the drain plug reaches the upper limit point and the lower limit point of the raising and lowering by forward and reverse rotation of the motor, the open sensor 116 and the close sensor 117 are turned on to stop the rotation of the motor.

  In FIG. 6, a motor (driving unit) 23 is installed in the shaft rod portion 2, and the plug body portion is slid in the axial direction, the speed reducing mechanism 5, the rotation transmission shaft 221 for raising and lowering the drain plug.
