JPS586949Y2 - Western style flush toilet - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to a Western-style flush toilet.

In general, when using a flush toilet, especially for women, water is sprayed not only when flushing feces, but also during use to muffle the sound of defecation, so the water used is extremely wasteful. It was the economy.

The present invention eliminates the above-mentioned drawbacks and provides a water-saving flush toilet that can save water by generating an onomatopoeic sound similar to the sound of water being discharged during use.

The water-saving flush toilet of the present invention will be explained below with reference to the drawings.

In FIG. 1 and the second page, reference numeral 1 denotes a Western-style flush toilet, and a lid 3 is mounted on a toilet seat 9 of a main body 2 so as to be openable and closable.

A small speaker 4 is embedded in the lid 3 with its cone facing toward the surface of the lid 3, and a white noise generator 5 connected to the small speaker 4 is attached.

Further, a microswitch 6 is connected to the white noise generator 5, and the microswitch 6 is attached to the peripheral edge 7 of the lid body 3, and when the lid is closed, an operation button 8 of the microswitch 6 is pressed. The toilet seat 9 on the top of the main body 2 is pushed in to open the contacts, but when the lid is opened, the operating button 8 is opened and the contacts are closed.

FIG. 3 shows a circuit diagram of the above embodiment, in which the white noise generator 5 and the microswitch 6 are connected in series to the power supply 10, and the small speaker 4 is connected to the white nozzle generator 5. That will happen.

It is preferable that each of the above-mentioned members be constructed to be highly moisture-proof, and it is preferable that the power source 10, for example, a small dry cell battery, be incorporated into a moisture-proof casing (not shown) of the white noise generator 5.

The white noise generator 5 itself is configured to amplify the sound of white noise similar to the sound of water spray, such as the out-of-tuned sound in an FM receiver, and send it to the speaker.

That is, the white noise generator 5 is configured as shown in FIG. 4, for example.

In the illustrated white noise generator, a relatively large current is passed through the first stage transistor Tri to obtain thermal noise, which is amplified by the transistor Tr2 and then filtered through the filter F.
A sound frequency around 350 KHz is taken out through the transistor Tr3, amplified by the transistor Tr3, and detected through the detection circuit DC to obtain vertically symmetrical white noise.

The white noise thus obtained is preferably applied to a power amplifier PA incorporated in the white noise generator 5, and the small speaker 4 is driven via the power amplifier PA.

Thermal theory The white noise generator 5 described above can be integrated into an IC and can be miniaturized.

Therefore, in the present invention, when the lid 3 is opened and the toilet seat 9 disposed facing the lid 3 is separated from the toilet seat 9, the microswitch 6 is automatically closed, and the circuit shown in FIG. When the power source 10 is turned on, the white noise generator 5 as shown in FIG. 4 is driven.

As a result, even if water is not sprayed during excretion, an onomatopoeic sound similar to that before water is sprayed is emitted from the small speaker 4 embedded in the lid 3 to the used shrine.

In the above-described embodiment, instead of the microswitch 6, a non-contact switch that closes when the user sits on the toilet bowl 1 may be used.

Further, although the above-mentioned embodiment shows a Western-style flush toilet, in the case of a Japanese-style flush toilet, the same effect can be obtained by attaching a switch to the door or a foot switch to the footrest.

According to the flush toilet of the present invention configured as described above, when the lid 3 is lifted during use, a pseudo-preparation state, such as before draining, can be automatically obtained, and as a result, there is no need to waste water. As a result, significant practical effects can be achieved, such as significant water savings.
