Description

[Detailed description of the invention] "Purpose of the invention" (Field of industrial application) The present invention relates to a flushing operation device for a simple flush toilet.

(Conventional Cleaning Operation Device) FIG. 5 is an exploded perspective view showing the installation state of the simple flush toilet 1. A conventional cleaning operation device 2 (hereinafter referred to as a conventional device) is installed in a water conduit 3 that communicates between the simple flush toilet 1 and a low tank (not shown). Although not shown in the drawings, the simple flush toilet 1 is installed in a pump-type toilet tank buried underground. Therefore, a dish-shaped flapper valve is pivotally attached to the toilet bowl outlet in order to prevent cold air, bad smells, etc. from blowing up from inside the toilet tank, and to prevent filth from being splashed up due to dropping. Therefore, the conventional device 2 is equipped with both a structure for supplying water into the toilet bowl and a structure for opening the flapper valve.

The conventional device 2 has only one operating handle 4, and by using the operating handle 4 in three different operating methods, the water supply status to the simple flush toilet 1 and the opening/closing status of the flapper valve can be changed. be. The configuration of the conventional device 2 will be explained based on FIGS. 5 to 8 in accordance with the respective usage conditions.
In addition, FIG. 6 shows the conventional device 2 along the pipe axis of the water conduit 3.
7 is a front sectional view of the conventional device 2, and FIG. 8 is a left sectional view of the conventional device 2.
FIG. 2 is a right sectional view showing the operation converting device 7 by cutting the right side thereof.

The first operation method of the conventional device 2 is performed when cleaning the toilet bowl and discharging waste after urinating or defecating. When the operating handle 4 is rotated toward the front, the peripheral cam 5a of the cam component 5 attached to the operating handle 4 via the driven rod 4a moves as shown in FIG.
As shown in FIG. 6, it comes into contact with the valve operating rod 6b of the flush valve 6, which constitutes the main body of the conventional device 2, and causes it to tilt. Therefore, the valve body 6a is separated from the valve port 6d of the valve seat 6c, and water is supplied to the simple flush toilet bowl 1. At the same time, in the operation conversion device 7 attached to the driven rod 4a (see FIG. 7), as shown in FIG.
Since a will push down the shaft rack 7b,
A drive transmission device 8 consisting of a cable 8a and a tube 8b connected to the shaft rack 7b is a closing weight 1 for a flapper valve of a simple flush toilet 1 as shown in FIG.
This will push up a. Therefore, the inside of the toilet bowl can be cleaned and the waste can be discharged.

The second and third operating methods in the conventional device 2 are as follows:
Do both before defecating. First, in the second operating method, the operating handle 7 is rotated so as to be slightly pushed in the opposite direction to the rotation direction. Therefore, as shown in FIG. 8, the shaft rack 7b of the operation conversion device 7 rises, and the hook 7d is inserted into the locking recess 7c between the projections protruding from the back surface of the shaft rack 7b.
becomes engaged. For this reason, the drive transmission device 8
The sliding movement is locked. In the third operating method, the operating handle 4 is pulled out to the right in FIGS. 5 and 7. As shown in FIG. 7, the axial long surface 5b of the cam component block 5 attached to the driven rod 4a of the operating handle 4 comes into contact with the valve operating rod 6b, causing it to tilt. Water is provided. However, in this case, since the closed state of the flapper valve in the simple flush toilet 1 is locked together with the sliding of the drive transmission device 8 as described above, the water supply is stored in the toilet bowl.
This prevents dirt, etc. from adhering to the inner surface of the toilet bowl.

(Problems to be Solved by the Invention) The three operating methods in the conventional device 2 are selectively used by one operating handle 4.
However, those who use the toilet for the first time have little understanding of how to operate it, and are often unable to take full advantage of the functions of the simple flush toilet 1. Of course, for those who are accustomed to using the conventional device 2, this was very confusing. Needless to say, erroneous operation of the conventional device 2 will unnecessarily increase the amount of water stored in the toilet tank.

The present invention has been developed in view of the above-mentioned circumstances, and allows even a first-time user to easily understand the different uses, prevents erroneous operations, and effectively utilizes the capacity of the toilet tank. The purpose of the present invention is to provide a new cleaning operation device (hereinafter referred to as the proposed device).

``Structure of the invention'' (Means for solving problems) The gist of the proposed device is that a flushing operation rod and a water storage operation rod are attached to a flush valve interposed in the water supply channel to a simple flush toilet. In the flush valve, a valve body with a valve operating rod is pressed against a valve seat, and an eccentric cam for tilting the valve operating rod is attached to the flushing operating rod. At the same time, an operation conversion device is provided which transmits linear power via a drive transmission device to a flapper valve pivotably mounted at the discharge port of the simple flush toilet, and the water operation rod contacts the valve operation rod of the flush valve. The valve operating rod is provided so that it can be tilted or moved forward or backward at any possible position.

(Function) In the proposed device, the operating rod that supplies water to the simple flush toilet can be operated separately for the first operating method and the third operating method out of the three operating methods that were conventionally required. There is. In other words, after urinating or defecating, as usual, by rotating the operating handle such as the operating handle attached to the washing operating rod, the eccentric cam opens the flush valve, and at the same time, the operation conversion device opens the flush valve. Open the toilet flapper valve. Therefore, the inside of the toilet bowl is cleaned and the filth inside the bowl is discharged. On the other hand, before defecating, there is an operating handle (not necessarily a handle-shaped one) attached to a water storage operating lever, which is separate from the washing operating lever.
operate. Therefore, the flush toilet valve is opened by the water storage operation lever, and water is supplied to the simple flush toilet bowl.
In this way, since the operation structure for supplying water to the simple flush toilet is made separate, the difference between the operation after urinating and defecating (in short, after defecating) and the operation before defecating (in short, before defecating) is clear. , and there is no risk of erroneous operation. Therefore, there is no need to increase the amount of water stored in the pump-type toilet tank. Regarding the mechanism for locking the flapper valve of a simple flush toilet, even if the flapper valve is locked incorrectly, the amount of water stored in the toilet tank will not increase. It may be attached to the operation conversion device or may be provided independently.

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

FIG. 1 is a perspective view showing a simple flush toilet 1 to which the present device is attached. The present device is provided with two operation handles for supplying water to the simple flush toilet bowl 1. One of them is the operation handle 10,
The other one is push button 17.

FIG. 2 is a front sectional view of the proposed device. A reservoir operating rod 18 is connected to the push button 17. The reservoir operation rod 18 is positioned so as to face the valve operation rod 21 of the flush valve 20, which constitutes the main body of the proposed device as shown in FIG. There is. As shown in Figure 2,
The water reservoir operation rod 18 is urged by a spring 19 in a direction to be pushed out to the left outside of the main body case 22, and when the push button 17 is pressed, the water reservoir operation rod 18 tilts the valve operation rod 21. It's becoming like that.

As shown in FIG. 2, a cleaning operation rod 11 is connected to the operation handle 10. An operation conversion device 13 and an eccentric cam 12 are attached to the cleaning operation rod 11. The eccentric cam 12 is located at the end of the cleaning operation rod 11 and directly above the valve operation rod 21. When the eccentric cam 12 is viewed from the side, it is as shown in FIG.
The valve operating rod 21 of 0 is now tilted. Further, the configuration of the operation conversion device 13 is similar to that of the conventional device 2.
It is almost the same as that of (see Figure 8), and the fourth
As shown in the figure, the fan-shaped pinion 14 and the shaft rack 15
It consists of Further, the shaft rack 15 is connected to a flapper valve (not shown) of the simple flush toilet 1 via a drive transmission device 8. Also,
A locking recess 15a is formed in the rear surface of the shaft rack 15, and a hook 16 is pressed toward the rear surface of the shaft rack 15.

In this way, in the present device, after urinating and defecating (in short, after defecating), the operation handle 1 shown in FIG.
0 is rotated, and the push button 17 is pushed in before defecating (in short, before using the toilet). Therefore, there is no mistake in the water supply operation to the simple flush toilet bowl 1. Originally, the operating method of operating handles, switches, etc. is something that is memorized by linking it to the state obtained by the operation, and this device focuses on this point and separates the operating lever related to water supply as an individual component. There are characteristics.

(Study of Alternative Aspects) In the embodiment described above, the operating handle 10 and the push button 17 are positioned opposite to each other, but this is a configuration for directing each operation to be performed with a different hand. be. By doing so, the operator can learn the operating method from the viewpoint of using the left hand before using the toilet and using the right hand after using the toilet, and further reliability can be achieved. It also has the advantage of being easy to explain to first-time users. However, this is not limited to
For example, the push button 17 may be placed on the front side. In addition, the push button 17 may be shaped like a lever by using the water storage operation rod 18 as a lever, or an eccentric cam 12 similar to the washing operation rod 11 may be attached to the water storage operation rod 18 to provide a handle. It is possible to make it into a shape. 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, there is no possibility of making a mistake in the water supply operation to the simple flush toilet.
As for the pump-out type toilet tank, it becomes possible to use its capacity for only the necessary minimum amount of washing water and filth. Furthermore, it has many excellent advantages, such as allowing even inexperienced users to operate it accurately and fully utilize the functions of the simple flush toilet.
