Description

  The present invention relates to a toilet flushing tank apparatus that can switch the amount of washing water flowing from a tank body to a toilet bowl to a large washing water amount and a small washing water amount, and to freely set the respective water amounts.

  Conventional tank drainage adjusting devices are roughly classified into a drain valve device unit and an operation handle device unit. The present invention relates to an operation handle device portion, and there are the following technologies in the field.

  When the spindle that is linked to the rotation of the operation handle is rotated to the drain valve body open state, the cam provided on the spindle and the rod disposed on the periphery are locked, and the spindle is fixedly held, When drainage is carried out and the water level in the tank drops by a certain amount, the rod is pulled by the connecting member of the floating body that slides down the outer peripheral surface of the overflow pipe, the locked state is released, and the drainage stops. There is a lock mechanism for a cam and a rod, and an overflow pipe in a fixed position is used for unlocking. (For example, refer to Patent Document 1).

  In addition, a damper device is provided between the tank outer wall of the handle rotation part and the operation handle.When the spindle rotates in the drain valve opening direction as the handle rotates, the drain valve body having an urging force in the valve closing direction is The spindle immediately rotates in the valve closing direction, but this rotation speed is due to the rotational resistance caused by the viscous resistance of the damper device. When the rotation angle is small, there is also a mechanism that delays for a short time and adjusts the required amount of drainage. (For example, refer to Patent Document 2).

  Also, a timer device provided to act on the spindle is fixed to the wall surface via a bracket on the inner wall side of the tank, and the return rotation speed is delayed by the timer device only when the spindle drains and rotates. The valve closing of the member is delayed and the drainage is adjusted. This mechanism acts only during large-scale drainage and is intended to reduce the amount of water (dead water) remaining in the tank. (For example, refer to Patent Document 3).

The object is to realize a device that can freely adjust the amount of large and small drainage.

  In order to achieve the above-mentioned object, the present invention has a drain valve body for discharging the stored water in the tank linked to the spindle linked to the operation handle, and moving the spindle to the operating position. The drain valve body is opened, and when the spindle operating position is small drainage, the drain valve body is closed by the water flow.When the spindle operating position is large drainage, the drainage is completed. In the tank drainage device that closes the valve body and returns the spindle to the non-operating position, the spindle is provided with an interlocking rod having an L-shaped tip, and the base is fixed around the spindle mounting hole on the inner wall of the tank. A suspended rotary body is provided on the central shaft provided above, with the lower portion biased toward the spindle. The rotating body is provided with a notch to insert the interlocking rod that rotates and rotates at the proper drainage position at the periphery where the rotation trajectory of the interlocking rod is difficult, and at the upper end of the periphery, and the spindle side lower part is exposed to gravity by exposing the water surface from the water It is characterized by the fact that a heavy object that acts to release the interlocking rod lock state is suspended in the water with a chain by causing the rotating body to reversely rotate against the spring due to its action It is.

  In the second problem solving means, the rotating body described in the first problem solving means is a small drainage rotating body (hereinafter referred to as a small rotating body), and is provided on one side of the substrate with the spindle interposed therebetween. A rotating body according to the first problem solving means is provided on the opposite side as a large drainage rotating body (hereinafter referred to as a large rotating body) except for a heavy object that hangs down. The large rotating body is formed by providing a large cutout portion in the lower part of the periphery in contact with the interlocking rod and extending the lower part to the small rotating body side. The small rotating body is added to the heavy object hanging from the lower end with a connecting tool, and a hook-shaped connecting rod is added to the distal end to extend the small rotating body. However, when the added heavy object rotates due to the increase in gravity due to the water surface exposure, the connecting rod rotates the large rotating body against the spring and unlocks the interlocking rod fitted with the large rotating body. It is characterized by this.

  FIG. 1 is a perspective view of an essential part of one embodiment of the present invention. The interlocking rod 11 that rotates integrally with the spindle 10 is fixed near the base of the spindle, and the distal end portion 12 bent into an L-shape of the interlocking rod 11 is fitted with a rotatable cylindrical portion 13 so that the spindle and Rotate in parallel position. On the base 17 fixed to the tank inner wall 16, the small rotating body 14 is disposed on the right side of the spindle, and the large rotating body 15 is disposed on the left side. FIG. 2 is a perspective view of the base 17 fixed to the tank inner wall 16, and the (small) projection 18 </ b> A and the (large) projection 18 </ b> B provided on the base 17 have a central axis of the small rotating body 14. 19A and the central shaft 19B of the large rotating body are provided, and the small rotating body 14 and the large rotating body 15 are respectively installed in a suspended form.

  In FIG. 3, the small rotating body 14 and the large rotating body 15 are separated from a part 21 </ b> A around the small rotating body 14 by the urging force of the (small) spring 20 </ b> A and the (large) spring 20 </ b> B on the base 17. The part 21B around the large rotating body 15 is pushed out so as to enter inside the circumferential locus 22 drawn by the interlocking rod, while the (small) rotation stopper 23A on the base and the (large) rotation The stopper 23B is adjusted to the optimum contact position with the interlocking rod 11.

  When the front end portion 12 of the interlocking rod 11 is rotated and raised from below at the same time as the spindle by the handle operation, the (small) periphery 21A and the (large) periphery 21B on the spindle side of the rotating body slide on the interlocking rod 11, It is pressed. When the interlocking rod 11 rises and rotates to the appropriate operating position of the small drainage or the large drainage at the upper end of each periphery, the interlocking rod 11 is inserted (small). A notch 24A and a (large) notch 24B are provided. The (small) bottom surface 25A and (large) bottom surface 25B of the notch are curved surfaces that support the interlock rod 11 with the (small) center axis 19A and (large) center axis 19B of the respective rotating bodies. The (small) upper surface 26A and the (large) upper surface 26B are projected in an eave-like shape to prevent excessive rotation of the interlocking rod 11.

  The center part of the tank is arranged so that the (small) heavy object 28A and (heavy) heavy object 28B hanging from the lower tip 27 extending to the spindle side of the lower rotating body 14 do not contact the tank inner wall 16. A suspension rod 29 (see FIG. 5) is provided at the tip, and a (small) heavy object 28A for a small rotating body is provided at the tip thereof by a (small) ball chain 30A, followed by (large). A heavy load 28B for a large rotating body is suspended in the tank and the water full of washing water W0 by the ball chain 30B. Each heavy object has a structure close to a specific gravity of 1 in consideration of buoyancy in water.

  A connecting rod 33 having a key-shaped tip 32 at the most distal end 31 of the small rotating body 14 is extended in the direction of the large rotating body 15.

  A large cutout portion 34 is provided in the lower portion on the spindle side of the large rotation body 15 so as to incorporate the connecting rod 33 of the small rotation body 14, and the lower extension 35 is formed by extending in the direction of the small rotation body 14. .

  The connecting rod 33 of the small rotating body 14 contacts the large cut portion 34 of the large rotating body 15 from the stationary position of the small rotating body 14 to the unlocked state of the interlocking rod 11 for the small drainage in FIG. Instead, as shown in FIG. 8, when the small rotating body 14 further rotates, the connecting rod 33 of the small rotating body 14 contacts, slides, and compresses the lower extension 35 of the large rotating body 15. To do.

  The operation of the above configuration will be described below. In FIG. 7, when the handle (not shown) is turned to the small washing water side, the interlocking rod 11 rotates in a counterclockwise direction with a circular locus 22 to contact and slide the periphery 21A of the small rotating body 14. When the small-sized drainage operation angle θ1 is reached by moving and compressing, the cut-out portion 24A of the small-sized rotating body 14 urged by the spring 20A inserts the interlocking rod 11, and drainage continues. Even if the interlocking rod 11 is further rotated upward, it is stopped at the eaves portion 26A on the upper surface of the notch portion.

  FIG. 7 is an operation diagram immediately before the unlocking of the interlocking rod for the small-sized washing water drainage. When the small-scale drainage amount reaches an appropriate amount, the water level in the tank drops to W1 and hangs in the water (small ) When the heavy object 28A is exposed to the water surface and increases in gravity, it acts on the lower end portion 27 of the small rotating body 27 to rotate the small rotating body 14 counterclockwise against the spring. Thereby, the lock of the interlocking rod 11 is released, so that the spindle returns, the drain valve is closed, and the drainage stops. Note that the amount of waste water for small use is freely adjusted by the length of the ball chain 30A connecting the (small) heavy object 28A and the shape of the (small) heavy object 28A. Further, the strength of the drainage water is adjusted by the magnitude of the ascending rotation angle θ1 of the interlocking rod 11.

  FIG. 8 is an operation diagram at the time of draining the washing water for general use. When the handle (not shown) is turned to the washing water side for general use, the interlocking rod 11 rotates clockwise, and the periphery 21B of the general rotating body 15 is moved around. When the large drainage operating angle θ2 is reached by contact, sliding and pressing, the notch 24B of the large rotating body 15 biased by the spring 20B inserts the interlocking rod 11, and drainage continues. Is done. As long as the water level in the tank reaches the small drainage amount W1, the connecting rod 33 does not touch the large rotating body 15 even if the small rotating body 14 rotates. After that, if the drainage continues, the connecting rod 33 becomes the large rotating body. When the water surface in the tank comes into contact with the lower extension 35 and falls to the water surface W2 having the appropriate amount of drainage for large use, the small rotating body 14 is further counterclockwise due to the increase in gravity due to the exposure of the heavy object 28B. Therefore, the state-of-the-art linkage rod 33 also rotates downward and counterclockwise.

  The lower portion of the large rotating body 15 and the lower portion 35 of the cut-out portion 34 in the direction of the small rotating body are contacted, slid and pressed by the connecting rod 33 of the small rotating body. The body 15 is rotated clockwise against the spring, the locked interlocking rod 11 is released, the spindle is restored, the drain valve is closed, and the drainage stops. The amount of washing water for general use can be adjusted freely according to the length of the ball chain 30B that connects the heavy object 28A and the heavy object 28B, and the shape of the heavy object 28B. Is done. Further, the strength of the water flow of the large drainage is adjusted by the magnitude of the rising rotation angle θ2 of the interlocking rod 11. By the way, in order to make the water flow of the general waste water stronger, when the rising rotation angle θ2 of the interlocking rod 11 is increased, the drain valve body 36 is always influenced by the buoyancy and always has a force in the valve closing direction. Shall be.

  As an example, the connecting rod 33 and the (large) heavy object 28 </ b> B are removed from the small rotating body 14, while the (small) heavy object 28 </ b> A of the small rotating body 14 is disposed below the large rotating body 15. A similar heavy object may be suspended, and the interlocking rod 11 may be unlocked independently.

  In addition, this invention is not restricted to said embodiment, In the range which does not deviate from the summary, it is possible to implement in various aspects.
