Description

[Detailed description of the invention] "Purpose of the invention" (Field of industrial application) This invention relates to a flushing operation device for simple flush toilets installed in areas where public sewage facilities are underdeveloped. It is something.

(Conventional Simple Flush Toilet Cleaning Operation Device) FIG. 6 is a side sectional view showing a situation where a Japanese-style simple flush toilet is installed. A simple flush toilet is configured to discharge filth, etc. in the toilet bowl to a pump-type toilet tank buried underground using a small amount of flushing water. Its structure will be briefly explained. As shown in an enlarged view in FIG. 7, the toilet main body 1 has a hemispherical valve body 2 (hereinafter referred to as a half-ball) attached to a discharge port 1b that opens at the bottom of the toilet bowl. A pedal rod 3a that protrudes toward the front side of the toilet main body 1 is connected to the half ball 2, as shown in FIG. (shown by the two-dot chain line in Figure 7),
Further, when the depression operation is released, the opening is rotated so as to return to the original closed state. Further, a wire cable 4 is connected to the rotation base 3b of the pedal rod 3a, and the flush valve 5 of the water conduit 7 opens in conjunction with the deep depression of the pedal 3.
Toilet bowl washing water and the like are supplied from the tank 6 to the toilet bowl main body 1. The flash valve 5 includes a valve seat 8 having a valve port 8a that opens along the water flow direction of the water pipe 7, and a valve seat 8, as shown in FIG. Valve body 9 to close
and an operating lever 11 connected via a lever fulcrum 10 to a valve operating rod 9a protruding from the valve body 9. The wire cable 4 is connected to the operating side end of the operating lever 11. That is, when the wire cable 4 is pulled by depressing the pedal 3 as described above, the operating side end of the operating lever 11 is pulled down, so that the valve operating rod 9a of the valve body 9 is pushed up in the opposite direction. Become. Therefore, the valve body 9 separates from the valve seat 8, and the flash valve 5 becomes open. Also, if the operating lever 11 is pushed down on its operating side,
Since it is possible to simply supply water into the toilet bowl main body 1, it is possible to create a reservoir of water in the toilet bowl 1a in preparation for toileting. Therefore, before defecating, etc., first push down the operating lever 11 of the flush valve 5 to create water in the toilet bowl 1a, and after defecating, press the pedal 3 deeply to release the toilet main body 1.
At the same time, the inside of the toilet bowl 1a is washed.

(Problems to be solved by the invention) Generally, in Japanese-style toilets, the person uses toilet paper after defecating in a half-slumped position. Therefore, if
If the Japanese-style toilet bowl is a flush type, the user operates a lever (or handle) to start flushing, and then arranges the clothes while the toilet bowl is being flushed. However, in the case of the above-mentioned simple flush type, the pedal 3 for starting the flushing operation protrudes from the front side of the toilet main body 1. I have to get off the floor. Therefore, after using toilet paper, the user first arranges his/her clothes on the upper floor of the step, then steps down to the lower floor and operates the pedal 3. Such an order not only amplifies the sense of disgust both visually and olfactory, but also because the clothes must be prepared in silence, without the sound of washing, which is a problem for women and others. It was something that was highly disliked.

By the way, Japanese-style toilets are classified into those that can be used for both urination and men's urination, and those that are exclusively used for urination, depending on how the toilet itself is installed. In other words, if the floor of the toilet room is formed with a step as in the above embodiment, and the toilet main body is installed on the upper floor of the step, it becomes a double-use type.
If the toilet bowl itself is installed on the flat floor of the toilet room, it can be used exclusively for urination. However, in a simple flush toilet, as mentioned above, on the front side of the toilet main body 1,
Since the pedal rod 3a and the pedal 3, which are essential to constructing a simple flush toilet, protrude, it cannot be installed on a flat toilet room floor for exclusive use of urination. For this reason, all Japanese-style toilets with simple flushing had to be constructed as dual-purpose toilets. In addition, in toilet rooms with individual urinals or women-only toilet rooms, it is troublesome to go up and down the floor on the step above the height of the toilet body, and the construction area becomes larger than necessary. Due to these inconveniences, there was an extremely high need for construction specifically for feces.

The present invention was developed in view of the above-mentioned circumstances, and it is possible to start flushing after using the toilet without getting off the upper floor of the step, and it also provides a Japanese-style toilet with a simple flush type. The purpose of the present invention is to provide a new cleaning operation device (hereinafter referred to as the "proposed device") that can be used exclusively for feces.

``Structure of the invention'' (Means for solving problems) The gist of the proposed device is that the main feature of the device is a flush valve installed in a water pipe that guides toilet bowl flushing water, etc. to the main body of a simple flush toilet. The flash valve has a valve operating rod protruding from a valve body that biases a valve seat to close the valve, and a driven shaft of an operating handle is installed close to the valve operating rod in an intersecting manner. is provided with a circumferential cam that tilts the valve operating rod by rotation of the operating handle on a shaft circumferential surface corresponding to the valve operating rod, and a circumferential cam that tilts the valve operating rod by rotation of the operating handle, and a sliding surface of the operating handle on the shaft circumferential surface adjacent to the circumferential cam. A shaft surface cam is provided that tilts the valve operating rod when operated, and the driven shaft has an opening at the base or end thereof at the bottom of the toilet bowl of the toilet main body via a power converter that converts rotational force into linear power. A drive transmission device is connected to a flapper valve pivotally mounted to the discharge port.

(Function) When the operating handle is rotated, the circumferential cam of the driven shaft also rotates, so that the valve operating rod of the flash valve is tilted by being pushed by the circumferential cam. Therefore, in the flush valve, the valve body is separated from the valve seat, and the water conduit becomes in a water flow state. Therefore, toilet bowl cleaning water is supplied into the toilet bowl of the toilet bowl body. Further, a drive transmitting device is connected to the driven shaft of the operating handle via a power converting device, and by rotating the operating handle as described above, the drive transmitting device is moved in a straight line from the power converting device. The flapper valve that closes the toilet bowl outlet is driven to open by receiving power. In other words, by rotating the operating handle, the flapper valve opens and the flushing water for the toilet bowl is simultaneously supplied on the toilet main body side. On the other hand, when the operating handle 4 is slid in the push-in or pull-out direction, the shaft surface cam of the driven shaft also slides, so that the flush valve is pushed by the shaft surface cam. The valve operating rod will now be tilted. Therefore, water is supplied into the toilet bowl of the toilet main body, but at this time, the power converter attached to the driven shaft does not transmit linear power to the drive transmitter,
The flapper valve on the toilet body also remains closed. For this reason, the supplied water is stored in the toilet bowl of the toilet main body, and a pool of water is created in preparation for toileting. Note that the sliding operation of the operating handle as described above may be performed before using the toilet, or may be performed after using the toilet as a preparation for the next user.

(Example) The present invention will be described below based on drawings showing examples thereof.

FIG. 1 is a perspective view showing a simple flush type Japanese-style toilet to which the present device is attached. The present device mainly consists of a flush valve 12 interposed in a water pipe 7 that connects the toilet body 1 and the tank 6 with each other.

FIG. 2 is a side sectional view of the flush valve 12 cut along the pipe axis of the water conduit 7 and viewed from the left side. The flash valve 12 consists of a valve seat 13 and a valve body 15. The valve seat 13 has a valve port 13a that is
The opening is perpendicular to the water flow direction of the water pipe 7. The valve body 15 is horizontally biased and closed with respect to the valve seat 13 by a coil spring 14, and has a valve operating rod 15a that protrudes laterally from the valve port 13a of the valve seat 13. have. The biasing force of the coil spring 14 can be adjusted to some extent by adjusting the degree of screwing of the adjustment cap 21. And, directly above the valve operating rod 15a,
A cam component block 18 attached to the shaft end of a driven shaft 16 (indicated by a broken line), which will be described later, is positioned.

FIG. 3 is a front sectional view of the flush valve 12 taken along the axis of the driven shaft 16. The driven shaft 16 is connected to the flash valve 12
It is installed horizontally in a direction orthogonal to the valve operating rod 15a at a position close to the valve operating rod 15a, and its shaft center portion is supported by a bearing 19. The bearing 19 is inserted into the driven shaft 16 with a slight circumferential gap, and is capable of sliding the driven shaft 16 in a sliding direction along its axis and in a rotating direction about the axis. It is held in A cam component block 18 is attached to the driven shaft 16 at the shaft end corresponding to the valve operating rod 15a,
An operating handle 17 is attached to the shaft base on the other end side, and a power converter 24 is attached to the shaft base near the operating handle 17. The driven shaft 16
In this case, the cam component block 18 at the end of the shaft is attached to the bearing 1.
A coil spring 21 is inserted through the coil spring 21 which urges the coil spring 21 in the direction of pulling it away from the coil spring 9 . Further, a stroke regulating cavity 19a is recessed in the inside of the bearing 19, and the stroke width of the sliding movement of the driven shaft 16 is adjusted by contact with a collar 20 fitted to the driven shaft 16. are becoming regulated. Therefore, the operating handle 17 can be slid in the pulling direction (to the right in FIG. 3), and returns to its original position by the coil spring 21 when the operation is released. It is also possible to perform rotational operations.

The cam component block 18 has a generally truncated conical outer shape, and includes a circumferential cam 22 having a cam surface formed along its circumferential direction, and an axial surface having a cam surface formed along its axial direction. A cam 23 is provided. As shown in FIG. 2, the circumferential cam 22 is formed so that its diameter increases smoothly toward the eccentric top portion 22a that tilts the valve operating rod 15a. In addition, the shaft surface cam 23, as shown in FIG.
The valve operating rod 15a is formed so that its diameter increases smoothly toward the large diameter portion 23a that tilts the valve operating rod 15a. Therefore, when the operating handle 17 is rotated or slid, the valve operating rod 15a is tilted in either case, the water conduit 7 (see FIG. 1) is brought into a state of water flow, and the water is drawn from the tank 6 to the toilet main body 1. Water will be supplied to

The shaft base of the driven shaft 16 to which the power converter 24 is attached is chamfered so that its cross-sectional shape is a regular hexagon. Cut this chamfer,
When viewed from the operating handle 17 side, it is as shown in FIG. The power converter 24 consists of a fan-shaped pinion 25 and a shaft rack 26 that meshes with the fan-shaped pinion 25. At the lower end of the shaft rack 26, a drive transmission device 2 is provided.
7 is connected. The drive transmission device 27 is a tube 27 that is flexible for bending, just like a camera release (remote control device for a shutter).
A wire cable 27a is slidably inserted into the inside of the cable 27b, and its output end is connected to a flapper valve to be described later. Therefore, when the operating handle 17 is rotated, the fan-shaped pinion 25 will push down the shaft rack 26,
Linear power is transmitted to the drive transmission device 27.

FIG. 5 is a side sectional view showing the vicinity of the outlet 1b of the toilet main body 1. A flapper valve 30 is pivotally attached to the outlet 1b of the toilet main body 1 and is pivotable about a pivot shaft 30a to open and close the outlet 1b. The pivot shaft 30a is bent so that both ends protruding to the outside of the toilet tube 29 provided so as to surround the flapper valve 30 are directed downward and in the lateral direction opposite to the flapper valve 30. Hereinafter, for convenience, the downwardly bent shaft portion of the pivot shaft 30a will be referred to as a vertical rod 30b.
The shaft portion bent laterally from the lower end of 0b is called a horizontal rod 30c). Further, a closing weight 31 is attached to the tip of the horizontal rod 30c, and the outlet 1b of the toilet main body 1 is opened by the flapper valve 30.
It is designed to keep it closed.

The drive transmission device 2 is attached to the outer wall of the toilet tube 29.
7 is fixed, and a ring-shaped connector 28 that becomes the output end of the wire cable 27a of the drive transmission device 27 is loosely fitted into the vertical rod 30b of the pivot shaft 30a. . Therefore, as described above, when linear power is transmitted to the drive transmission tool 27 by rotating the operating handle 17, the connecting tool 28 is connected to the vertical rod 30b of the pivot shaft 30a.
is pushed out, and the flapper valve 30 begins to open as shown by the two-dot chain line. Incidentally, if the vertical rod 30b of the pivot shaft 30a is tilted so that the bent portion at the lower end thereof is closer to the flapper valve 30 than the bent portion at the upper end, as the operating handle 17 is rotated, Since the connecting tool 28 of the drive transmission tool 27 moves along the vertical rod 30b of the pivot shaft 30a,
The connecting tool 28 comes to extend straight.
Therefore, the drive transmission device 27 is not subjected to excessive bending force, etc., and the operation of the operating handle 17 becomes extremely smooth.

The operation status of the device of the present invention constructed in this way will be explained. For example, when defecating or the like, the user slides the operating handle 17 so as to pull it out to the right in FIG. As a result, as shown in FIG. 3, the shaft surface cam 23 comes into contact with the valve operating rod 15a of the flush valve 12 and tilts it.
Water is supplied from the tank 6 into the toilet bowl 1a of the toilet main body 1, and is stored within the toilet main body 1.
As mentioned above, in order to prevent the operating handle 17 from rotating when the operating handle 17 is slid, in this embodiment, the power converter 24 is provided with a mechanism shown in FIG. 4. A locking mechanism 35 such as the one shown in FIG. The locking mechanism 35 has two to three locking recesses 2 recessed in the back surface of the shaft rack 26.
6a, and a hook 36 that is pressed toward the locking recess 26a. Therefore, before sliding the operation handle 17, the shaft rack 26
The hook 3 is inserted into the locking recess 26a of the shaft rack 26 by slightly rotating it in the direction in which the flapper valve 30 is raised (the direction opposite to the direction in which the flapper valve 30 is opened).
6 is fitted, and the sliding movement of the drive transmission device 27 is locked. As described above, since water continues to be supplied while the operating handle 17 is being pulled, the amount of water stored in the toilet bowl can be adjusted as desired. Also, after finishing your errand,
The operating handle 17 is rotated in the direction in which the shaft rack 26 is lowered. Therefore, as shown in FIG.
This causes the tank to come into contact with and tilt it, and water is supplied from the tank 6 into the toilet bowl 1a of the toilet main body 1. Moreover, in this case, the power converter 24
Since the linear power is transmitted to the drive transmitting device 27 by (see FIG. 3), the flapper valve 30 is opened and the toilet bowl 1a is washed. On the other hand, if you need to urinate, etc., use the operating handle 1 from the beginning.
By rotating the flapper valve 7 in the direction in which the shaft rack 26 descends, the flapper valve 30 is opened and the toilet bowl flushing water is supplied at the same time. The closing movement of the flapper valve 30 relies on the falling force of the closing weight 31 as shown in FIG. 5, but as shown in FIG.
By attaching a torsion coil spring 33 that generates a repulsive force between the discharge port 1b and the discharge port 1b, the discharge port 1b can be reliably closed.

Unlike the conventional toilet bowl shown in FIG. 6, the Japanese-style simple flush toilet equipped with the present device does not have the pedal rod 3a or the pedal 3 protruding toward the front side of the toilet body 1, so the toilet room is flat. It can be installed on the floor and used exclusively for feces.

(Study of Alternative Embodiments) The device of the present invention may be installed at any position in the water conduit that connects the toilet main body and the tank. Moreover, although the toilet main body has been described only in a Japanese style, by making the tank a high tank, it becomes possible to attach the present device to a Western style simple flush toilet. In this way, the configuration of the present device can be changed as appropriate depending on the mode of implementation.

"Effects of the invention" As is clear from the above explanation, according to the simple flush toilet flushing operation device according to the present invention, the operating handle for starting the flushing operation is a guide that connects the toilet body and the tank with each other. Since it is installed in the water pipe, you can start washing without having to get off the upper floor of the step after using the toilet. Therefore, it becomes possible to perform post-urinary treatment in the same order as in a Japanese-style flush toilet, and the visual and olfactory disadvantages of the conventional toilets are eliminated. In addition, with the development of the proposed device,
Since a Japanese-style simple flush toilet can be installed on a flat toilet room floor, it has many excellent advantages, such as the ability to construct a simple flush toilet exclusively for urination.
