BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a flush toilet according to an embodiment of the present invention;
FIG. 1 is a front view showing an embodiment of the flush toilet drainage device of the present invention. As shown in the example of FIG. 1, the drainage device (1) is disposed inside a low tank (2) provided in a flush toilet.

In the example of FIG. 1, the low tank (2) is provided with a ball tap (3) therein, and the washing water is supplied from the ball tap (3) into the low tank (2). . When a certain amount of washing water is accumulated, the washing water is automatically stopped. As this structure, a conventionally known structure can be appropriately adopted. A drain port (4) is formed at the bottom of the low tank (2).
The drain port (4) communicates with the toilet bowl (not shown). The drain port (4) is provided with a drain valve (5) as a valve body for opening and closing the drain port. This drain valve (5)
Is connected to an arm (7) provided in the drainage device (1) via a chain (6) as a connecting member.
The arm (7) is rotatable, as will be described later. By rotating upward, the drain valve (5) is lifted, the drain port (4) is opened, and the washing stored in the low tank (2). Water can be drained to the toilet. On the other hand, when it rotates downward from that state and returns to the initial state shown in FIG. 1, the drain valve (5) closes the drain port (4), stops outflow of the washing water, and enters the low tank (2). A predetermined amount of washing water can be stored.

FIGS. 2 and 3 are an enlarged front view and a side view of the drainage device illustrated in FIG. 1, respectively. For example, as shown in these Figures 2 and 3, plate Mounting the drainage device (1) (8) is provided. Driving means (9) is fixed to this mounting plate (8) by screws (10). The driving means (9) is provided with a rotating shaft (not shown) so that the arm (7) can be rotated in the direction of the arrow shown in FIG. Is connected to the arm (7). There is no particular limitation on the configuration and structure of such a driving means (9), and any conventionally used means can be appropriately used. A motor to allow the electric drive, further as to transmit a rotational force of the motor to the arm (7), provided such a clutch mechanism and deceleration mechanism for turning on and off the connection between the motor and the arm (7) be able to.

On the other hand, as illustrated in FIG. 3, the arm (7) penetrates from the rotation shaft of the driving means (9) to the back side of the mounting plate (8), and bends laterally. It has the shape of a mold. A weight (11) is attached to the tip. The mounting plate (8) is provided with through holes (12) so as to allow the arm (7) to pass therethrough.
Are formed. The arm (7) projects through the through hole (12) to the back side of the mounting plate (8).

In this example, the outer diameter of the weight (11) is substantially the same as the outer diameter of the arm (7).
In this way, when assembling the drainage device (1), for example, as shown in FIG. 4, the arm (7) is kept in a state in which the weight (11) is attached to the distal end of the arm (7) in advance. Can be made to penetrate through the through hole (12) and protrude to the rear surface side of the mounting plate (8). When the arm (7) is passed through the mounting plate (8), the weight (11) does not interfere, and there is no trouble that the weight (11) must be attached after passing through the arm (7).

A spring (13) as an elastic body is connected to the drive means (9) side of the arm (7). As the elastic body, the spring (13) is not limited to, but it may also be a rubber or the like. As the spring (13), various types such as a torsion coil spring and a compression coil spring can be appropriately adopted. Also, a manual lever (14) is provided on the driving means (9) side of the arm (7) so as to enable manual rotation of the arm (7) in consideration of a power failure or the like. The manual lever (14) is appropriately drawn out from the front or side of the low tank (2) illustrated in FIG. 1,
It is also possible to connect the handle or the like thereto.

FIG. 5 is an exploded side view of the drainage device. As illustrated in FIG. 5, the arm (7), drive means (9) and hand lever (14) is integral with the mounting plate (8) by a set stand is unitized. For this reason, the attachment of the drainage device (1) to the low tank (2) illustrated in FIG. 1 can be performed in a unit unit, and the installation in the low tank (2) having a narrow internal space is simple and easy. Further, in the event that the drainage device (1) has some trouble, the unit can be removed and taken out from the raw tank (2). For example, low tank (2)
To, by forming a through hole to the extent that the inside unitized drain device as illustrated in FIGS. 2 and 3 (1) can be inserted, inserting the arm (7) in the through hole After that, the driving means (9) can be inserted into the inside of the low tank (2) together with the mounting plate (8), and the workability of the above-mentioned mounting and dismounting is further improved.

FIG. 6 is a rear view of the drainage device. For example, as shown in FIG. 6, the spring (13) has one end fixed to the back surface of the casing (15) of the driving means (9), and the other end connected to the arm (7). . The spring (13) is stretched by being pulled in the direction of the arrow shown in FIG. 6 with the upward rotation of the arm (7) to generate an elastic force.

Further, stoppers (16) and (17) are provided on each of the arm (7) and the mounting plate (8), and the rotation limit of the arm (7) is defined. For example, in the drainage device (1) described above, the driving unit (9) is connected to a circuit unit (18) for supplying power and operating and controlling the driving unit, as illustrated in FIG. be able to.

In cleaning the toilet, for example, when the switch of the remote controller is turned on and the driving means (9) is operated, the rotating shaft of the driving means (9) is rotated, and is moved in the direction of the arrow shown in FIG. The arm (7) rotates upward, and this state is maintained for a certain time. At this time, the spring (13) is expanded, and the elastic force is accumulated. Then, by the rotation of the arm (7), the drain valve (5) illustrated in FIG. 1 is lifted through the ball chain (6), and as a result, the drain port (4) of the low tank (2) is opened. The washing water stored in the low tank (2) is drained from the drain port (4) to the toilet.

After a lapse of a predetermined time, the arm (7) is in a free state because the clutch mechanism provided in the driving means (9) is disengaged. Then, the elastic force accumulated in the spring (13) is released, and at the same time, the arm (7) rotates downward by the gravity acting on the weight (11). The arm (7) stops when the stopper (16) provided on the arm (7) hits the stopper (17) of the mounting plate (8), and returns to the initial state. At this time, the drain valve (5) closes the drain port (4) as illustrated in FIG. 1, and the drainage of the washing water ends. Thereafter, the washing water is stored in the low tank (2) to a predetermined amount.

As described above, in the drainage device (1),
The arm (7) can be returned to the initial state by both the gravity acting on the weight (11) and the elastic force of the spring (13). Also, for example, the spring (13) may be deformed due to a change in the surrounding environment due to rust or the like and may be broken, or the spring (13) may come off during the operation of the arm (7). Even if something goes wrong, the arm (7) is surely returned to the initial state by the weight of the weight (11). Therefore, the drain valve (5) can surely close the drain port (4) after draining a predetermined amount of the washing water, thereby preventing the washing water from flowing out. The washing water does not flow out more than necessary, making it economical.

FIG. 7 is an exploded front view illustrating a method of attaching a weight to the arm. For example, as shown in FIG. 7, an external thread (19) is formed at the tip of the arm (7), and an internal thread (20) is formed inside the weight (11). Can be. Female thread (20)
By rotating in the direction of the arrow shown in FIG.
The weight (11) can be screwed in and fixed to the arm (7). In this case, since a fixing member such as a screw or a nut is not required, assembling of the drainage device (1) is further simplified and facilitated, and the drainage device (1) is inexpensive. When the arm (7) is made of, for example, a resin molded product, it is easier to manufacture the male screw portion (19), and it is easier to manufacture the female screw (20) for the weight (11) from the viewpoint of processing. Is also convenient.

Of course, the present invention is not limited by the above examples. It goes without saying that various aspects are possible for details such as the configuration and structure of the low tank and the driving means.

[0025]

As described in detail above, according to the present invention, even if the elastic body is deteriorated due to a change in the surrounding environment and is deformed, cuts off, or comes off during operation, the present invention can be applied to the arm tip. The arm can be reliably returned to the initial state by the weight of the provided weight.
Water outlet of the low tank is reliably closed by the valve body after drainage of a predetermined quantity of washing water, the washing water does not become a release flow. The washing water is prevented from flowing out more than necessary, and the economy is stably maintained. Also, according to the present invention,
When assembling the water system, attach the weights in advance.
The arm can be passed through the through hole in the
