[Industrial applications]

 The present invention relates to a low tank for a toilet that always keeps water supplied to a flush toilet.

[0002]

[Prior art]

 Conventional low tanks for toilets have a drain port on the bottom wall of the low tank, and this drain port is opened and closed in conjunction with a drain lever that is rotatably installed on the side wall of the low tank and is closed with an opening / closing plug that discharges all water at once. There is. In addition, a ball tap is provided on the water supply pipe that supplies water to the low tank, and this ball tap is a vertically movable valve opening / closing lever that opens and closes the valve part of the ball tap, and an arc-shaped sensing lever with its tip lowered downward. Was screwed on, and the float was fixed to the tip of the sensing lever. This float moves up and down according to the water level in the low tank to raise and lower the sensing lever, and at the height of the full water level in the low tank, the sensing lever is positioned at the tip of the sensing lever where it closes the valve part of the ball tap. The float is stuck. As a result, the water in the low tank was always kept full. However, because the float was installed at a high position in the low tank and the amount of water stored was large, and because the float was fixed to the tip of the sensing lever, the installation position could not be lowered, and the amount of drainage to the flush toilet was large. As a result, water was continuously discharged to the flush toilet even after the waste had been completely drained, and much water was wasted. For this reason, for the purpose of saving water, it was devised to put bottles, cans, blocks, etc. in the low tank to reduce the volume in the low tank. It damaged the mouth opening / closing plug, causing drainage failure and water leakage.

[0005]

[Action]

 As described above, in the present invention, a person operates the operation panel in advance, and the wire covered with the flexible tube connected to the float is slid and held in the flexible tube to a predetermined position, and the force for biasing the float is applied. Face the sensor lever to the predetermined position and slide along the sensor lever to hold it. If the wire tension is released by operating the wire operation panel, the force that biases the wire in the direction opposite to the tension direction causes the float to slide along the sensing lever, causing the wire to bend. Instead, the float inside the low tank can be easily held at the specified position of the sensing lever from an external wire operation panel, and the height position of the float can be changed. In the ball tap, if the water level of the water supplied from the water supply pipe rises to the height of the float mounting position, the float is pushed up together with this water level, and the sensing lever linked to this float operates to close the valve section and close the low tank. The water supply to the inside is stopped and the water is stored. Further, if the height of the mounting position of the float is increased, the amount of water stored in the low tank increases, and if it is lowered, the amount of water stored in the low tank decreases. Since the wire connecting the wire operation panel and the float slides in the flexible tube, the wire covered with the flexible tube is placed on the periphery of the opening of the raw tank body from the inside of the raw tank and is brought out to the outside. If the wire covered with the flexible tube is placed outside the raw tank by placing the outer peripheral edge of the raw tank lid on the opening edge, the wire will not come into direct contact with the raw tank lid, and The friction does not prevent the wire from sliding. In this way, in a low tank that stores a certain amount of water, if the toilet user turns the drain lever provided on the rotor and opens the opening / closing plug of the outlet, all the water in the low tank will be transferred to the flush toilet at once. In the empty low tank that was drained through the drainage pipe, the float that had been pushed up by the stored water dropped due to its own weight, the sensing lever linked to this float lowered, and the valve part of the ball tap opened. , Start water supply from the water supply pipe into the low tank. By repeating these steps, the low tank is always kept in a full state with a prescribed amount of water stored. Also, by adjusting the amount of water stored in the low tank from the wire operation panel, the amount discharged to the flush toilet can be changed, resulting in excellent water saving. If the sensing lever has a substantially inverted L-shape as described in claim 2, a part of the sensing lever is formed in a substantially vertical state in the low tank, so that the float can slide on the sensing lever in the vertical portion. If the float is moved up and down, the horizontal width can be suppressed and the sliding distance of the float can be set longer even in a narrow low tank, and the water storage volume can be widened and water saving can be improved. If the sensing lever having a substantially inverted L shape is defined in claim 3, if the connecting tool is detachably attached to the valve opening / closing lever in advance, and the sensing lever body is detachably attached to this connecting tool, the inside of the narrow raw tank is reduced. However, it is possible to easily attach the elongated sensing lever body that is the vertical part of the sensing lever. Most of the sensing lever and the valve opening / closing lever of the ball tap are screwed together, so that the sensing lever may be a substantially inverted L-shaped sensing lever comprising a connector and an elongated sensing lever body. For example, screw the connecting tool into the valve opening / closing lever in advance, insert the sensing lever body into the insertion hole of this connecting tool, and fasten it with the screw to detachably attach the connecting tool and the sensing lever body. If it is attached to the, it is not necessary to screw the valve on the valve opening / closing lever while rotating the sensing lever itself, and it can be easily attached even in a narrow raw tank, improving workability. In the wire operation panel according to claim 6, the wire connected to the float by a person holding the knob and sliding it along the opening that becomes the passage to the predetermined locking groove to hold it in place. Can be held by sliding for a predetermined distance, and the float can be held at a predetermined position of the sensing lever.

In this embodiment, the knob 21 of the wire operation panel 20 (see FIG. 4) previously attached to the outer surface of the low tank 2 is slid along the passage 22 and the knob 21 is fitted into the predetermined locking groove 23 and held. To do. By sliding the knob 21, the wire 17 attached to the knob 21 slides in the flexible tube 18, and the float 15 connected to the wire 17 moves to the sensing lever body 13 in the direction opposite to the urging force of the tension coil spring 16. Along with this, the sensing lever main body 13 is pulled toward the base end thereof, and is held at that position. In this way, the float 15 can be operated from the outside to easily change the mounting height position of the float 15 to the sensing lever 12.

[Effect of device]

 As described above, according to the present invention, the wire operation panel provided in the toilet room except the inside of the low tank with the wire covered with the flexible tube from the inside of the raw tank to the outside and the float inside the raw tank are provided. Since the float is biased in the direction opposite to the pulling direction of the wire, even if the tension of the wire operation panel is released, the wire is not bent by the biasing force and smoothly moves to the predetermined position along the sensing lever. It can be slid up to and held, and the height of the float mounting position can be changed. In this way, it is possible to easily and reliably change the amount of water stored in the low tank by setting the height of the float mounting position to a predetermined height by operating the wire operation panel, and not to waste the flush toilet. A low tank that suppresses drainage and is excellent in water saving. With the sensing lever having a substantially inverted L shape as claimed in claim 2, the lateral width can be suppressed, and even in a narrow raw tank, it may interfere with the operation of another device in the raw tank. Moreover, the float can be vertically slidably attached to the vertical position of the sensing lever, and the adjustment area of the low tank water storage was widened, resulting in excellent water conservation. If the sensing lever has a substantially inverted L shape as described in claim 3, the installation work is easy even in a narrow raw tank, and the sensing lever having the substantially inverted L shape as described in claim 4 is provided. If it is a sensing lever, it is not necessary to install it while rotating the sensing lever body, the installation work is very easy, and it is possible to install a sensing lever with a long vertical portion, which has a wide adjustment area of water storage and is very difficult to save water. It will be excellent. As described in claim 5, a wire whose outer periphery is covered with a flexible tube is placed on the peripheral edge of the opening of the raw tank body, and the outer peripheral lower edge of the lid of the raw tank is placed on the wire, and the wire is provided inside and outside the raw tank. Even if the wire is attached, since the outer circumference of the wire is covered with a flexible tube, the wire itself does not directly contact the lid of the raw tank or the opening edge of the raw tank body, and friction with the lid of the raw tank or the upper edge of the raw tank body does not occur. Since there is no concern that the wire will not slide, it is possible to securely slide the wire with the wire operation panel without the need to open a hole in the low tank body and with a simple installation work. With the wire operation panel according to claim 6, the wire can be easily moved in the flexible tube by a very simple operation of holding the knob connected to the wire in the predetermined locking groove along the opening serving as the passage. Moreover, it can be surely slid and held, and the float can be easily and reliably set at a predetermined mounting height position.
