Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an onomatopoeic sound generating device, and more particularly to an onomatopoeic sound generating device used for muffling the sound of defecation in a general flush toilet.

In general, the amount of water used by a user in a flush toilet, ie, the amount of water used by a toilet user to flush waste and purify the toilet bowl after use, should be approximately constant. However, in general households as well as offices and companies where people often come and go, toilet users are aware of the presence of people around them, flush water before there is any excrement in order to muffle the sound of defecation, and flush water after using the toilet. The drawback was that precious water was being consumed for purposes other than its original purpose, since the purified water had to be flushed once again. It is well known that the amount of water wasted in this way is enormous even in a single day.

The present invention has been made to eliminate the above-mentioned drawbacks of the prior art, and its purpose is to change the luminous intensity inside the toilet when the toilet user opens the door of the flush toilet. A photoreactive sensor detects a change in the amount of water, and the onomatopoeic sound generator is activated for a certain period of time to continuously generate a sound similar to the sound of running water. The goal is to eliminate the need to flush water to flush toilets, thereby significantly reducing the amount of water used in flush toilets. Another purpose is to allow the user to flush water at any time to flush out excrement, as usual, without causing any discomfort or inconvenience to the user. Still another object is to provide a simple and compact onomatopoeia generator by electronically generating onomatopoeias.

In short, the present invention provides an onomatopoeia generator used in flush toilets, which includes an electronic fixed storage device that stores binary scale control data for generating a plurality of series of sounds, and the scale control data as contents. an electronic temporary storage device for selectively temporarily storing program signals; and an electronic temporary storage device selectively operated to generate a selection signal to select a particular group of scale control data in the electronic permanent storage device. a scale selection device, which operates in response to a selection signal of the scale selection device, programs scale control data of the electronic permanent storage device in the electronic temporary storage device; an arithmetic device that sequentially reads scale control data selected from the device at scheduled timing; a digital-to-analog conversion device that converts the read-out scale control data into voltage;
It is characterized by comprising a speaker that outputs the output of the analog conversion device as a scale, and a light intensity responsive sensor that applies an electrical signal to the scale selection device in response to a change in light intensity in the toilet to make it effective. That is.

The present invention will be explained below based on embodiments shown in the drawings. In FIG. 1, a flush toilet 1 is a private room and is normally used by opening and closing the door 2.
Inside the toilet 1, there is a toilet bowl 4 equipped with a water storage tank 3, and after using the toilet, the toilet user U operates a manual lever 5 provided on the water storage tank to flush away excrement. As shown in the figure, an illumination lamp 7 is attached to the upper part of the toilet wall 6 facing the door 2, and an onomatopoeic sound generator 1 is attached to the lower part of the wall.
0 is installed. As is clear from FIGS. 3 and 4, the onomatopoeic sound generator includes a light intensity response sensor 8, a scale selection device 20, and a central processing unit 21.
, an electronic fixed storage device 22 , an electronic temporary storage device 23 , and a digital-to-analog conversion device 24
and a speaker 9, and as shown in FIGS. 1 and 2, it is connected to a power source 1 by a cord 11.
Connected to 2. The scale selection device 20 has a plurality of scale selection signals, and these scale signals are selectively _specified by operating respective selection switches S ₁ , S ₂ . Various onomatopoeic scales can be selected at will, such as babbling sounds and bird calls. Electronic fixed storage device 22
is ROM (READ ONLY MEMORY),
It stores a plurality of binary scale control data for generating onomatopoeia. The central processing unit 21 receives the designated scale selection signal from the scale selection device 20 and selectively organizes the scale control data in the electronic permanent storage device 22 according to a predetermined program, and the electronic temporary storage device 23 is configured to store the RAM ( RANDOM ACCESS
MEMORY) and temporarily stores the program contents. and a central processing unit 21, an electronic permanent storage device 22, and an electronic temporary storage device 23.
constitutes a microcomputer. As shown in FIG. 1, when the door 2 of the toilet 1 is closed, the incident light A of the lamp 7 is reflected by the door 2 at a certain angle, and the reflected light A' shown by the imaginary line is reflected by the light intensity reaction sensor 8. It is becoming more and more perceivable. Next, when the toilet user opens the door 2, the light from the lamp 7 is reflected on the toilet user and becomes reflected light A'', so the sensor 8 detects the change in the luminous intensity, and the onomatopoeic sound generator 1
0 at a predetermined potential for a predetermined time to operate this device. The above relationship between the lamp 7 and the light intensity response sensor 8 is a simple example, and in the present invention, even if the lamp is not used, the sensor 8 can detect changes in light intensity even in the sunlight according to the opening and closing of the door 2. It is something to be sensed. In short, the configuration is such that the sensor 8 only needs to detect changes in the luminous intensity or brightness within the toilet 1.

The present invention is constructed as described above, and its operation will be explained below. In FIG. 1, when a toilet user U opens the door 2, the light beam A of the lamp 7
-A' changes to A-A'', and the sensor 8 detects the change in luminous intensity and becomes the expected potential, operating the scale selection device 20, which generates a pre-selected scale selection signal. The central processing unit 21 operates upon receiving the scale selection signal, selectively organizes the scale control data in the electronic fixed storage device 22 according to a scheduled program, and temporarily stores the program contents in the electronic temporary storage device 23. Then, based on this program, the central processing unit 21 continuously reads scale control data from the electronic fixed storage device 22 at the timing of a transmitter or the like (not shown).These binary scale control data The digital-to-analog converter 24 receives the signal, converts it into a voltage, amplifies it, and outputs it from the speaker 9 as an onomatopoeia of the planned scale.After a certain period of time, the planned potential of the onomatopoeic sound generator 10 disappears, and onomatopoeia is generated. The operation stops.In Figure 2, the state of light A-A' of the lamp 7 while the toilet user is using the toilet is as shown, and it is assumed that the generation of onomatopoeia has already stopped at this time. However, there may be cases where it is necessary to generate onomatopoeic sounds.In this case, if the toilet user U makes some movement, such as slightly shifting his body or moving his hand, the sensor 8 detects the change in the light intensity in the toilet. The onomatopoeia generating device 10 operates to generate an onomatopoeic sound by sensing and maintaining the predetermined potential again.The relationship between the light emitting body and the light intensity response sensor 8 is limited by the size of the place where the sensor is used. However, it is clear that the customer volume of a typical private toilet 1 sufficiently guarantees the response of the sensor 8 to changes in luminous intensity or brightness.

As described above, in the onomatopoeic sound generating device of the present invention, an onomatopoeic sound, for example, the sound of running water, is generated simply by opening the door of the flush toilet, so the toilet user U does not need to simply flush water to eliminate the sound of excretion. Be aware of this and don't waste water.

Next, if there is excrement and it is really necessary to flush the water, the user can operate the manual lever 5 to flush water from the water storage tank 3 to the toilet bowl 4 and flush the excrement as usual. At this time, as the toilet user U moves his or her body, the luminous intensity within the toilet 1 may change and onomatopoeia may occur, but this is not a problem.

Although FIGS. 1 and 2 show a Western-style flush toilet with a water storage tank, it does not have to be a water tank type, and it is of course possible to use a Japanese-style toilet. When using the toilet, the user U opens the door 2 and enters the toilet 1, so that the light intensity or brightness inside the toilet changes.

Further, the power source 12 may be an AC power source, a non-rechargeable dry battery, a storage battery, or a solar battery.

Since the present invention is configured and operates as described above, the user can hear onomatopoeia for a certain period of time just by opening the door of the flush toilet and entering the toilet.
For example, since the sound of running water or other sounds is continuous, if the user simply wants to muffle the sound of defecation, there is no need to flush, thereby significantly reducing the amount of water used in flush toilets. The effect that can be obtained is obtained. In addition, since there is no need to operate any specific parts other than the toilet door to generate onomatopoeic sounds, even users who do not know that the toilet is equipped with an onomatopoeic sound generator can hear the sound of running water when opening the door. By generating the onomatopoeic sound, the user knows that there is no need to waste water, and has the effect of being able to thoroughly use this type of toilet from then on.
Furthermore, if the user really wants to flush away excrement, water can be flushed at any time as before, so the user can use it as desired and has the advantage of not feeling strange or inconvenienced. Furthermore, since the sound is generated electronically without using a tape recorder, it is possible to provide a simple and compact onomatopoeia generating device, which is an invention of extremely high practical value.
