Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of an onomatopoeia generator installed in a flush toilet bowl.

[0002]

2. Description of the Related Art Conventionally, in order to dissipate the excretion sound generated when a toilet is used, an artificial sound generating apparatus has been used in which an artificial sound similar to the outflow sound of washing water is generated from a speaker to save water. However, since this onomatopoeia generator is a mechanism that reproduces an onomatopoeia signal stored in a storage element such as a ROM in advance, it is an offensive artificial sound and is different from a natural outflow sound. The person sometimes dared not use this kind of onomatopoeia, and could not achieve a sufficient water saving effect. Therefore, in order to generate a more natural outflow sound as an onomatopoeia, a device has been proposed in which a water discharge passage of a system different from the water supply flow path to the toilet bowl is provided and the water discharge sound from the water discharge passage is generated as an onomatopoeia. (For example, the actual Kaihei 3-621
66, Japanese Utility Model Publication No. 4-61168).

[0003]

[Problems to be Solved by the Invention] However, the actual Kaihei 3-6
The device proposed in Japanese Patent No. 2166 can generate an onomatopoeia until the toilet cleaning tank is filled with water, but when it is full, the onomatopoeia cannot be generated unless it is drained. Further, the device proposed in Japanese Utility Model Laid-Open No. 4-61168 overflows water discharge for artificial sound generation even after the toilet bowl cleaning tank is full, so that artificial sound can be generated even after full water. However, there is a problem that it is impossible to save water because the wash water is wasted.

[0004]

According to a first aspect of the present invention, there is provided an onomatopoeia sound generating device, which is provided with a toilet for accompaniment to an onomatopoeia, and has a path for circulating the stored water in the tank. It is an apparatus provided with a region where water falls and a power source for circulating water on the way.

According to a second aspect of the present invention, there is provided an onomatopoeia sound generating device which is provided with a toilet bowl, has a water absorption path for absorbing water stored in the tank, and which is provided in the middle of the water absorption path. It is an apparatus provided with a region where water falls and a power source for absorbing water.

According to a third aspect of the present invention, there is provided the artificial sound generating device according to the first or second aspect, wherein the artificial sound generating tank is provided inside the toilet bowl cleaning tank.

According to a fourth aspect of the present invention, there is provided an onomatopoeia generation apparatus according to the first or second aspect, wherein an opening for leading out the onomatopoeia is opened and closed on the wall surface of the onomatopoeia generation tank. This device is equipped with a damper.

[0008]

With the provision of an onomatopoeia sound generation tank associated with the toilet bowl, the stored water in the tank is circulated through the power source separately from the stored water in the toilet bowl cleaning tank to the water surface in the onomatopoeia sound generation tank. Since the running water sound generated when water is spouted is generated as an onomatopoeic sound, even when the cleaning tank is full of water, it is possible to generate an onomatopoeia without wasting the cleaning water. Further, as described in claim 3, by providing the onomatopoeia generation tank in the toilet cleaning tank, the structure becomes compact. Further, as in claim 4, when an opening for leading out the onomatopoeia and a damper for opening and closing the opening is provided on the wall surface of the onomatopoeia generation tank, and the damper is opened only when the onomatopoeia is generated, The onomatopoeic effect can be enhanced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An onomatopoeia generating apparatus according to the present invention will be described below with reference to the drawings. 1 and 2 are drawings showing a first embodiment of an onomatopoeia generating device according to the present invention, and FIG. 1 is a perspective view showing a whole flush toilet 2 with the onomatopoeia generating device 1 in a partially transparent state. 2 is a sectional view. In addition,
In FIG. 1, some pipes such as a water supply pipe are omitted. In the case 3 placed on the rear surface of the flush toilet 2, the low tank 4
The low tank 4 is divided into a toilet bowl cleaning tank section 6 by partitioning the inside with a partition plate 5 and an onomatopoeia generation tank section 7 that is stored only at a water level lower than the toilet bowl cleaning tank section 6. There is. The height of the partition plate 5 is set to a height obtained by opening a pipe gap 9 through which a water supply pipe or the like (see FIG. 2) is piped from the ceiling plate 8 of the low tank 4. The water level difference stored in the tank portions 6 and 7 is smaller than the amount of water supplied to the tank portion 6 from a water channel branched from the water channel or a water channel of another system when water is supplied to the toilet bowl tank 6, for example. It is made by supplying water into the above-mentioned onomatopoeia generation tank portion 7 with a water supply amount.

The onomatopoeia generation tank portion 7 is a storage tank for circulating the stored water and repeatedly ejecting water into the tank portion 7 to generate the water ejection sound at this time as an onomatopoeia. From the water outlet 10 formed in the lower portion of the onomatopoeia generation tank portion 7 to the onomatopoeia nozzle 14 arranged at the upper position of the tank portion 7 through the first switching valve 11, the pump 12 and the second switching valve 13. A circulation path 15 is formed to reach. The artificial sound nozzle 14 shown in FIG. 1 has three spouts 15a, 15b, 15c.
With.

The first switching valve 11 and the second switching valve 1
3 switches between the circulation path 15 and the hot water washing path 18 from the hot water tank 17 for supplying hot water to the shower nozzle 16 for hot water washing, and the pump 12 corresponds to the switching of the switching valves 11 and 13. , Works for circulation or for washing with hot water.

An artificial sound generating port 20 is opened on a side surface 19 of the artificial sound generating tank portion 7, and a damper 21 which is opened when circulating water is circulated in the case 3 corresponding to the artificial sound generating port 20. It is attached (see Figure 2).
The opening position of the artificial sound generating port 20 is not limited to the side surface 19 as a matter of course, but it is preferable to open the artificial sound generating port 20 at a position where splash water spouted from the artificial sound nozzle 14 is not applied to the toilet user.

The partition plate 5 shown in FIG.
2 is configured to open and close by rotating about 2 as a base point 22a, and as shown in the drawing, a lower plate 22 and a float valve 23
And 24 are connected by a chain 24 and the float valve 23
The partition plate 5 is automatically opened as water is moved upward, and the water stored in the onomatopoeia generation tank portion 7 is drained. Even with such a configuration, since the lower plate 22 is pressed toward the tank 7 side by the water pressure of the tank portion 6 while the circulating water is circulating,
There is no particular problem with the partitioning effect of the partition plate 5.

In the onomatopoeia generating device having the above structure,
When a dummy sound switch (not shown) provided to generate a dummy sound is operated, the pump 12 is driven in a state where the first switching valve 11 and the second switching valve 13 are switched to the circulation path 15 side. At this time, the water stored in the onomatopoeia generation tank portion 7 is circulated to the onomatopoeia nozzle 14 through the circulation path 15, and the water is discharged from the onomatopoeia nozzle 14 toward the water surface in the onomatopoeia generation tank portion 7. The outflow sound of water and its collision sound become imitative sounds. On the other hand, when a shower for washing with hot water is used, the first switching valve 11 is switched to the side of the hot water tank 17, and the second switching valve 13 is switched to the shower nozzle 16 for washing with hot water.

FIG. 3 is a sectional view showing a second embodiment of the onomatopoeia generating apparatus according to the present invention. In this example, the toilet bowl cleaning tank portion 6a and the onomatopoeia sound generating tank portion 7a are separately structured by the partition plate 5a extending to the ceiling plate 8. In this case, since the water supply into the toilet bowl cleaning tank portion 6a is supplied to the tank portion 7a through the lower plate 22, the water supply piping to the artificial sound generating tank portion 7a is not necessary. For this reason, no water supply noise is generated when water is supplied to the onomatopoeia generation tank portion 7a, so that a damper is not required and the onomatopoeia generation port 20
The portion of the case 3 corresponding to [3] may have a sliding door structure, for example. Other configurations are the same as those in FIG.

FIG. 4 is a sectional view showing a third embodiment of the onomatopoeia generating apparatus according to the present invention. In this example, a water absorption pipe 25 is erected from a lower position to an upper position of the onomatopoeia generation tank portion 7, and a water absorption tank 26 is arranged at this upper position. A water discharge pipe 27 that is curved downward is provided at the boundary between the water suction pipe 25 and the water absorption tank 26.
Further, a valve body 28 is provided so that the water collected in the water absorption tank 26 does not flow back through the water absorption pipe 25. The tip of the water discharge pipe 27 serves as an onomatopoeia nozzle 14. The air path 29 for sucking water through the water suction pipe 25 is
The switching valve 30 and the pump 3 from the upper position of the water absorption tank 26
1 is formed.

Therefore, in the onomatopoeia generation device shown in FIG. 4, when an onomatopoeia switch (not shown) provided for producing onomatopoeia is operated, the switching valve 30 causes the air passage 29 to move.
The pump 31 is driven and inhaled while being switched to the side. For this reason, the water stored in the onomatopoeia generation tank portion 7 is sucked up and discharged through the drain pipe 27 from the onomatopoeia nozzle 14 toward the water surface inside the onomatopoeia generation tank portion 7, and the outflow sound of the water is discharged. And the collision sound becomes an onomatopoeia. On the other hand, when using a shower for washing with warm water, the pump 31 is driven with the switching valve 30 switched to the side of the warm water tank 17.

5 to 7 are views illustrating an opening / closing mechanism of the damper 21. As shown in FIG. The damper 21 is configured to be opened only when the onomatopoeia is generated and closed for sound insulation when the onomatopoeia is not generated. The mechanism may be configured to open and close electrically using, for example, a motor and a gear, but as shown in FIGS. 5 to 7, it can also be opened and closed by the pressure of circulating water.

FIG. 5 shows a structure in which a pressure sensitive plate 32 that moves in response to the pressure of circulating water is inserted at the tip of the circulation path 15, and the pressure sensitive plate 32 and the lower part of the damper 21 are connected by a push rod 33. The damper 21 is opened like a door with the base shaft 34 as a rotation shaft. FIG. 6 shows a shutter 35 of a shutter type. A water pan 37 is provided from the upper part of the damper 35 by connecting a link 36, and the damper 35 is slid vertically by the pressure when circulating water is discharged to the water pan 37. It is an open structure. At this time, the waterproof cover 38 is attached to the case 3. In FIG. 7, the onomatopoeia generation port 20 is shielded by a shield plate 40 biased to a fixed position by a spring member 39, and circulating water is applied to the water receiving surface 41 formed by bending from the lower portion of the shield plate 40. Rotate the shielding plate 40 around the base point 42,
It is a structure in which the onset of the artificial sound generating port 20 and the shielding plate 40 is released by opening the polymerization.

FIGS. 8A to 8D are views showing a structural example other than the onomatopoeia nozzle 14 shown in FIG. FIG. 8 (A)
8B shows a drooping wide nozzle, and FIG. 8B shows a shower nozzle shape, which spreads downward and is dropped.
In addition, FIG. 8C shows a nozzle formed in a tapered shape.
FIG. 8 (D) shows two types of drainage ports 43, 44 of a drooping type and a horizontal type.
It is formed by branching. As described above, the structure of the onomatopoeia nozzle is not particularly limited, and since the volume of the onomatopoeia and its sound change depending on the capacity of the tank portions 6 and 7, the capacity of the pump 12, etc., these factors are considered. Then, it may be appropriately selected and adjusted.

FIG. 9 shows the case where the artificial sound generating device according to the present invention is installed in the system toilet. In this case, the artificial sound generating device 45 is installed in the wall of the unit 46 accommodating the pipe, and the damper 47 is installed. For example, it is provided at a location where the wall surface of the unit 46 is opened.

In the above embodiment, the toilet bowl cleaning tank portion 6 and the artificial sound generating tank portion 7 are configured by the partition plate 5, but the toilet bowl cleaning tank is provided separately from the tank. You may put in the onomatopoeia generation tank which consisted of a cylindrical case. Further, although the pump 12 is arranged as the power source of the circulation path 15, of course, the pump 1
The pressure is not limited to 2, and pressure from a pressurizing device or the like can be used. Further, the onomatopoeia generation switch (not shown) may be operated in conjunction with the switch that is turned on when the onomatopoeia generation port 20 is opened, or may be configured to interlock with the seating sensor.

[0023]

As described above, according to the present invention, even when the cleaning tank is full, it is possible to generate artificial sound as a natural running water sound without wastefully discarding the cleaning water. The water saving effect can be further achieved.
