Description

[Detailed description of the invention] "Purpose of the invention" (Field of industrial application) This invention is a simple flush toilet installed in a toilet room and connected to a pump-type toilet tank via a toilet pipe, etc. It is related to.

(Conventional Simple Flush Toilet) FIG. 9 is a partially cutaway side view of a conventional simple flush toilet. The simple flush toilet has a toilet tank sealing body 3 at an outlet 2a of a toilet bowl 2, which communicates with a scoop-type toilet tank via a toilet pipe 17 and the like. The toilet tank sealing body 3 is formed into a dish shape, and a water bottle weight 16 is attached in series to the other end side via the fulcrum 4 to form a lever structure. In other words, the toilet tank sealing body 3 becomes the point of action, and the water bottle weight 16 becomes the point of force. Further, the lever structure is set so that the force side is slightly heavier than the point of action side, and the toilet tank sealing body 3 is pressed against the discharge port 2a of the toilet bowl 2 too much. Therefore, a very small amount of water can be accumulated on the toilet tank sealing body 3 facing the inside of the toilet bowl 2. When the load of filth, washing water, etc. is added to this accumulated water load, the load on the side of the action point of the lever structure becomes heavier than the side of the force, and the toilet tank sealing body 3 opens as shown by the two-dot chain line. The filth, toilet bowl washing water, etc. in the toilet bowl 2 are caused to fall into the toilet tank. In addition, after the filth falls, the weight on the side of the toilet becomes heavier again, so the toilet tank sealing body 3 returns naturally and closes the outlet 2a of the toilet bowl 2, causing the bad odor in the toilet tank to spread into the toilet room. The atmosphere is separated from each other to prevent it from spreading.

(Problems to be solved by the invention) As mentioned above, the level of accumulated water in conventional simple flush toilets does not reach the inner peripheral surface of the toilet bowl 2, and filth is rubbed against the inner surface of the toilet bowl. It is not possible to prevent the product from adhering to the surface. Therefore, it has a drawback that the attached dirt cannot be completely washed away by just one cleaning. Moreover, the closed state of the toilet tank sealing body 3 is set such that the added load of the toilet tank sealing body 3 itself and the accumulated water load is maintained in equilibrium with the load of the water bottle weight 16 itself. Therefore, the toilet tank sealing body 3 can be easily opened by a very small additional load other than the accumulated water load. This was also one of the important conditions for conventional simple flush toilets. However, for this reason, the toilet tank sealing body 3 opens and moves every time there is defecation during defecation, causing the user to suffer from a bad odor inside the toilet tank. Moreover,
Once the toilet tank sealing body 3 is opened, the accumulated water above it naturally disappears, so that subsequent filth also comes into direct contact with and adheres to the toilet tank sealing body 3. I come to do it. Furthermore, when filth adheres to the toilet tank sealing body 3 as described above, the toilet tank sealing body 3 may remain in a half-open state,
The stench continued to plague the building until the filth was removed.

The present invention has been developed in view of the above-mentioned circumstances, and it eliminates the problem of bad odor inside the toilet tank, at least while defecating, and also eliminates the problem of filth on the inside of the toilet bowl and the sealing body of the toilet tank. The purpose of the present invention is to provide a new simple flush toilet bowl (hereinafter referred to as the "proposed toilet bowl") that does not have any adhesion.

``Structure of the invention'' (Means for solving problems) The gist of the proposed toilet is that it is a simple flush system that is installed by connecting the outlet at the bottom of the toilet bowl to a distribution pipe that leads to a scoop-type toilet tank. In the toilet bowl, a lever structure in which a toilet tank sealing body for closing the toilet bowl outlet from below is provided at one end of the lever shaft, and a closing force weight is provided at the other end of the lever shaft, and the lever structure a bottom opening mechanism that is connected to a lever shaft of the toilet via a wire cable or the like and transmits a sliding force in a direction in which the toilet tank sealing body is separated from the toilet bowl outlet; An air isolation mechanism locks at a proper position on the axis and presses and fixes the toilet tank sealing body against the toilet bowl outlet; It consists of a water supply mechanism that supplies water to the water stored in the toilet bowl, and the bottom opening mechanism, the air insulating mechanism, and the water supply mechanism are each provided so that they can be operated independently.

(Function) The toilet tank sealing body that closes the outlet of the toilet bowl is configured such that its closed position is fixed by an air insulating mechanism. The toilet tank sealing body is configured such that its closed and fixed state is not released unless the bottom opening mechanism is operated. Therefore, even if an additional load due to filth or the like is applied to the toilet tank seal, the toilet tank seal will never open. In addition, by operating the water supply mechanism, it is possible to supply water from the water tank to the toilet bowl at any time, regardless of whether the toilet tank seal is in the open or closed position. There is.
Therefore, a sufficient amount of water can be accumulated before using the toilet to prevent filth from adhering to the inner surface of the toilet bowl or the toilet tank seal.

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

FIG. 1 is a side sectional view of the toilet according to the present invention, and the sectional views of the toilet main body side (left side in the figure) and the water tank side (right side in the figure) with the cutting line A as the boundary are drawn differently. The toilet bowl of the present invention is characterized by having a bottom opening mechanism 5, an air insulating mechanism 6, and a water supply mechanism 7.
Note that the discharge port 2a of the toilet bowl 2 is connected to a toilet pipe (not shown) leading to a scoop-type toilet tank (not shown).
are installed so as to have a communicating relationship, and the toilet tank sealing body 3 is provided so as to close the toilet bowl outlet 2a from below, and furthermore, the toilet tank sealing body 3 is The closing force weight 9 is provided on the side of the point of action of the lever structure with respect to the fulcrum 4, and is provided on the side of the point of force via the fulcrum 4 and the lever shaft 9b, unlike the conventional simple flush toilet (see Fig. 9). ) is roughly the same as However, in the lever structure of the toilet according to the present invention, the closing force weight 9 is set to be considerably heavier than the load of the toilet tank sealing body 3, so that the closing force weight 9 is set to be considerably heavier than the load of the toilet tank sealing body 3, so that the toilet tank sealing body 3 is strongly pushed toward the outlet 2a of the toilet bowl 2. It's starting to be forced.

The bottom opening mechanism 5 is installed in a water tank 8 such as a low tank installed around the toilet bowl 2. FIG. 2 is an enlarged sectional view of the bottom opening mechanism 5, showing the inside thereof. As shown in the figure, the bottom opening mechanism 5 is formed by meshing a fan-shaped pinion 5a and a shaft rack 5b within a gear case 5c. The shaft rack 5b has a wire cable 10 connected to its lower end, and is connected to the closing force weight 9 by the wire cable 10, as shown in FIG. The wire cable 10
is slidably inserted into a tube that is flexible with respect to bending, just like a camera release (remote control device for a shutter). As shown in FIG. 4, the connection structure between the wire cable 10 and the closing force weight 9 is as follows.
A ring end 10a provided at the end of the closing force weight 9 is loosely fitted into a mounting hole drilled in a lever shaft 9b of the closing force weight 9. Therefore, the shaft rack 5b
(See Figure 2) by sliding it in the downward direction.
As shown by the two-dot chain line in FIG. 1, the forced closing weight 9 is pushed up via the wire cable 10 and lever shaft 9b, and the toilet tank sealing body 3 opens in the direction away from the toilet bowl outlet 2a. do. Further, if the shaft rack 5b (see FIG. 2) is slid in the upward direction, the closing force weight 9 is pulled down, contrary to the above, and the toilet tank sealing body 3 is moved to close. The wire cable 10 is protected from water stored in the water tank 8 by a standpipe 8a installed upright in the water tank 8.

Further, as shown in FIG. 2, a hexagonal hole is bored in the fan-shaped pinion 5a. FIG. 3 is a sectional view taken along the line BB in FIG. 1. As shown in the figure, a shaft end portion 11a of a bottom opening lever 11, which is attached to the outer surface of the water tank 8 with an exposed operating portion, is inserted into the hexagonal hole of the fan-shaped pinion 5a. The bottom opening lever 11 is formed in a hollow shape as shown in FIG. 5, and its shaft end 11a
has a hexagonal cross section. Therefore, by inserting the bottom opening lever 11 into the fan-shaped pinion 5a, the rotation of both is restrained integrally. Further, as shown in FIG. 2, a self-returning torsion coil spring 5d is attached to the fan-shaped pinion 5a between it and the gear case 5c. Therefore, by rotating the bottom opening lever 11, the fan-shaped pinion 5a rotates and drive is transmitted to the shaft rack 5b and the wire cable 10, so that the toilet tank sealing body 3 is opened. There is. Further, the closing movement of the toilet tank sealing body 3 is performed by the return action of the fan-shaped pinion 5a by the torsion coil spring 5d and the falling action of the closing force weight 9.

The air insulating mechanism 6 is attached to the bottom opening mechanism 5 as shown in FIG. 2 above. That is, two to three locking recesses 6a are provided on the rear surface of the rack surface of the shaft rack 5b provided at one end on the sliding axis of the wire cable 10 of the bottom opening mechanism 5. ,
The hook 6b is urged toward the locking recess 6a. Therefore, by rotating the bottom opening lever 11 so that the shaft rack 5b slightly slides upward, the hook 6b fits into the locking recess 6a of the shaft rack 5b and is locked. As a result, the wire cable 10 becomes immovable and the toilet tank sealing body 3 is fixed in a state that closes the outlet 2a of the toilet bowl 2.

The water supply mechanism 7 is also provided together with the bottom opening mechanism 5 and the air isolation mechanism 6. As shown in FIG. 3, the water supply mechanism 7 is comprised of a water supply handle 12 and a hanging shaft 13 from which a float valve 8b (see FIG. 1) is suspended. The rotation shaft 12a of the water supply handle 12 is inserted into the cylindrical hole (see FIG. 5) of the bottom-opening handle 11 in the bottom-opening mechanism 5, and can be rotated separately from the bottom-opening handle 11. ing. The hanging shaft 13 is inserted and fixed to the shaft end of the rotating shaft 12a of the water supply handle 12. Therefore, when the water supply handle 12 is rotated, the float valve 8b in the water supply tank 8 as shown in FIG.
Water comes to be fed into the toilet bowl 2 through b.

In addition, as shown in FIG. 3, the bottom opening handle 11
The water supply tank 8 is connected by the cylindrical housing 14.
It is designed to be attached to the side wall of the As shown in FIG. 6, the housing 14 has a mounting base 14a having a square cross section, and is configured to be prevented from rotating against the side wall of the water tank 8.

FIG. 4 is a perspective view showing a lever structure constituted by the toilet tank sealing body 3 and the closing force weight 9. The closing force weight 9 has a rectangular planar shape that is wider than the toilet tank sealing body 3, and has a rod-shaped metal member 9a embedded therein as shown in FIG. The lever shaft 8b that supports the closing force weight 9 is bent so as to double as a support shaft 9c which becomes the fulcrum 4 of the lever structure.

By the way, as shown in FIG. 1, in this embodiment, the mounting structure of the closing force weight 9 is devised. That is, by bending the lever shaft 9b so that the closing force weight 9 is located below the toilet tank sealing body 3, the load of the closing force weight 9 is transferred onto the toilet tank sealing body 3. It acts so as to strongly repel the added dirt load, and does not provide much resistance to the upward force from the bottom opening mechanism 5. Further, as shown in FIG.
By supporting the wire cable 10 by the tube housing 10b which is rotatable relative to the wire cable 10 (see FIG. 1), the wire cable 10 can smoothly extend and slide into the tube.

Furthermore, as shown in FIG. 7, the structure of combining the bottom opening handle 11 and the water supply handle 12 is devised so that the bottom opening mechanism 5, the air insulating mechanism 6, and the water supply mechanism 7 can be operated separately. be. That is, a triangular protrusion 12b is provided on the back surface of the water supply handle 12, and a fan-shaped recess 11b is provided on the surface of the bottom-opening handle 11. The position and shape of the recess 11b in the bottom-opening handle 11 are determined by the virtual shape drawn by the protrusion 12b when the water supply handle 12 is rotated. Therefore, the bottom opening handle 11 and the water supply handle 1
2 is combined, the protrusion 12b of the water supply handle 12 fits into the recess 11b of the bottom-opening handle 11, and the movements of the handles 11 and 12 are correlated with each other. That is, when the water supply handle 12 is rotated, the protrusion 12b simply touches the bottom-opening handle 11.
It only moves in an arc within the recess 11b, and has no effect on the bottom-open handle 11. However, when the bottom-opening handle 11 is rotated, the vertical step surface 1 of the recess 11b in the bottom-opening handle 11
1c and the protrusion 12b of the water supply handle 12 engage with each other, causing the water supply handle 12 to rotate accordingly. Therefore, when creating water in the toilet bowl 2, only the water supply handle 12 needs to be rotated, and when cleaning the toilet bowl after using the toilet, only the bottom opening handle 11 needs to be rotated. It's getting old.

The operating situation of the proposed toilet in this way is described in the 8th section.
This will be explained based on Figures A and B. Note that the bottom-opening handle 11 and the water supply handle 12 are connected to the water supply tank 8.
(See Figure 1), but Figures 8A and 8B are drawn from the front side. First, as shown in FIG. 2A, when defecating, etc., rotate the bottom-opening handle 11 to the right (towards the back of the water tank 8), and move the shaft rack 5b (see FIG. 2). Lock the toilet tank seal 3 (see Figure 1) in the closed position. Also, the water supply handle 12 is rotated to the left (to the front side of the water supply tank 8) to create a desired amount of water in the toilet bowl 2 (see FIG. 1). After the toilet is finished, as shown in FIG. Deliver pot washing water. On the other hand, when urinating, etc., only the bottom-opening handle 11 is rotated to the left (toward the front) from the beginning, as shown in FIG. Note that the operation of creating water in the toilet bowl 2 using the water supply handle 12 is not limited to before using the toilet, but may be performed after using the toilet and washing the toilet bowl.

(Study of Alternative Embodiments) The toilet bowl of the present invention may be a Western-style toilet bowl or a Japanese-style toilet bowl. However, when it is a Japanese style toilet,
Install the water tank 8 as close to the toilet body as possible,
It is desirable that the wire cable 10 is not too long. Further, the operating structure of the bottom opening mechanism 5, the operating structure of the air insulating mechanism 6, the operating structure of the water supply mechanism 7, etc. are not limited to those of the above embodiments, and for example, the bottom opening handle, the air insulating handle, the water supply mechanism, etc. The handles may be provided at different positions throughout the entire area including the periphery of the toilet bowl body. In this way, the detailed configuration and shape of the toilet bowl of the present invention can be changed as appropriate depending on the mode of implementation.

"Effect of the invention" As is clear from the above explanation, according to the simple flush toilet according to the invention, the blocked state of the toilet bowl outlet by the toilet tank sealing body can be fixed by operating the air insulation mechanism. be able to. In this state, the toilet tank sealing body will not open unless the bottom opening mechanism is operated, so the user will not be bothered by the foul odor inside the toilet tank while defecating. In addition, even when the toilet tank sealing body is in a fixed state blocking the toilet bowl outlet, the water supply mechanism
It can be operated independently. Therefore, any amount of water can be stored in the toilet bowl before using the toilet. In this way, the filth is prevented from directly rubbing against the inner surface of the toilet bowl or the toilet tank sealing member, so that it is possible to prevent the filth from sticking.
Furthermore, since the sticking of filth is prevented in this way, the toilet bowl and the toilet tank seal can be thoroughly washed away even in a single cleaning operation. Therefore, it has many excellent advantages, such as being able to suppress the use of a large amount of washing water (multiple washing operations), and allowing the capacity of the toilet tank to be used effectively.
