Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an onomatopoeic sound generating device, and in particular to an onomatopoeic sound generating device used to muffle the sound of defecation in general flush toilets. The present invention relates to an onomatopoeia generating device having an emergency alarm function in case it is necessary.

In general, the amount of water consumed by a user in a flush toilet, ie, the amount of water used by a toilet user to flush excrement and purify the toilet bowl after use, should be approximately constant. However, in public facilities such as offices, companies, department stores, schools, hospitals, stations, etc. where people often come and go, as well as in general households, toilet users are conscious of the presence of people around them and remove excrement to muffle the sound of defecation. Since the water is flushed before the toilet is empty and purified water is flushed again after using the toilet, the disadvantage is that precious water is wasted for purposes other than its intended purpose. It is well known that the amount of water consumed in this way is enormous even in a single day. Furthermore, it is well known that toilets are private rooms and there is a high possibility of crimes occurring there, and it is also well known that people often need help due to sudden illness or seizures in the toilets. However, the reality is that no consideration has been taken to prepare for such a situation.

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 photoresponsive sensor detects the change and activates the sound generator for a certain period of time to continuously generate a sound similar to the sound of running water, for example, so that the toilet user simply tries to eliminate the sound of defecation. The goal is to eliminate the need to flush water for 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 away excrement, as usual, without causing any discomfort or inconvenience to the user. Another purpose is to provide a simple and compact onomatopoeic sound generating device, and in particular, to prevent crimes and accidents in toilets by equipping this onomatopoeic sound generating device with an emergency alarm function for crime prevention or emergency relief. It is.

In summary, the present invention provides an electronic fixture storing binary scale control data for generating a plurality of sequences of sounds in a flush toilet that drains water and purifies the toilet bowl by operating a manual lever in one direction. a storage device; a temporary storage device for selectively temporarily storing a program signal having said scale control data; and a temporary storage device selectively operated to generate a selection signal; a scale selection device for selecting a specific group of the scale selection devices, the scale selection device being operable in response to a selection signal of the scale selection device to program the scale control data of the electronic fixed storage device in the electronic temporary storage device; an arithmetic unit that sequentially reads scale control data selected from the electronic fixed storage device at scheduled timings based on the program; and a digital processor that converts the read scale control data into voltage.
an analog converter; a speaker that outputs the output of the digital-to-analog converter as a musical scale;

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 attached.

In FIGS. 2 and 3, the onomatopoeia generator 10
A photoresponse sensor 8 is disposed on the front surface 10b of the container 10a, and inside the container there is a sound selection device 20, a central processing unit 21, an electronic fixed storage device 22, and an electronic temporary storage device. A device 23;
Digital-to-analog converter 24 and speaker 9
As shown in FIG. 1, it is connected to a power source 12 in the toilet 1 by a cord 11. The scale selection device 20 has a plurality of scale selection signals, and these scale selection signals are selectively specified by operating respective selection switches S ₁ , S _{2 .} . . sounds, birds chirping, etc.
Various scales stored in the electronic fixed storage device 22 can be arbitrarily selected. The electronic fixed storage device 22 is ROM (READ ONLY MEMORY)
It stores 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 ME
-MORY) and temporarily stores the program contents organized by the central processing unit 21. The central processing unit 21, the electronic fixed storage device 22, and the electronic temporary storage device 23 constitute a microcomputer.

As shown in FIG. 1, when the door 2 of the toilet 1 is closed, the incident light A of the illumination 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 response sensor 8. It's starting to be perceived. Next, when the toilet user U opens the door 2, the reflected light A' becomes unspecified with respect to the light intensity reaction sensor 8.
That is, the luminous intensity inside the toilet 1 changes. The light intensity reaction sensor 8 detects this change in light intensity, and the onomatopoeic sound generating device 1
0 at a predetermined potential for a predetermined time to operate this device. In addition, in FIGS. 1 and 2, the container 10 of the onomatopoeia generator 10
A switch button 13 for manual operation is provided on the front surface 10b of the photosensitive sensor 8.
This is for the toilet user U to operate the onomatopoeic sound generating device 10 when the toilet user U does not work. Furthermore, an emergency manual switch button 14 is arranged on the side surface 10c of the container 10a, and this is provided in relation to a specific scale selection switch button _S0 of the scale selection device 20 shown in FIG. This is designed to prevent crimes in the restroom, or in case someone needs help due to sudden illness, seizures, etc. When pressed, an emergency alarm sound is generated. ing.

The present invention is configured as described above, and its operation will be explained below. In FIG. 1, when a toilet user U opens the door 2, the reflected light A' of the illumination lamp 7 becomes unspecified with respect to the luminous intensity reaction sensor 8, and the luminous intensity inside the toilet 1 changes. The light intensity reaction sensor 8 senses the change in light intensity, and the electric potential reaches a predetermined potential, thereby operating the scale selection device 20 and generating a preselected 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 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 an oscillator (not shown).
The digital-to-analog converter 24 receives these binary scale control data, converts it into voltage, amplifies it, and outputs it from the speaker as an onomatopoeia of the planned scale. After a certain period of time, this onomatopoeia generator 1
The expected potential of 0 disappears, and the onomatopoeic sound generation operation stops.

In FIG. 1, the state of the light A-A' of the lamp 7 while the toilet user U is using the toilet is as shown in the figure.
It is assumed that the generation of onomatopoeic sounds has already stopped at this time. However, the need for further onomatopoeic generation may arise. In this case, if the toilet user U makes some movement, such as shifting his or her body a little or moving his arm, the sensor 8 detects the change in the luminous intensity inside the toilet and maintains the planned potential again, and the onomatopoeic sound generator 10 operates and generates onomatopoeia. Although the relationship between the light emitter and the light intensity responsive sensor 8 is limited by the space in which the sensor 8 is used, it is clear that the volume of a typical private toilet 1 is sufficient to ensure the reaction of the sensor 8 to changes in light intensity or brightness. It is. However, the illumination lamp 7 does not light up due to the filament of the light bulb being burnt out or some other inconvenience.
If the photoresponse sensor 8 does not work in the dark, the toilet user U can use the container 1 of the onomatopoeia generator 10.
When the manual operation switch button 13 provided on the front surface 10b of 0a is operated, this is applied as an electrical signal to the scale selection device 20 to enable it, and the onomatopoeic sound generation device 10 operates.

In addition, if the user U feels that he or she is in danger due to a criminal act in the toilet 1, or if he or she needs help due to a seizure or physical illness, the side 10c of the container 10a of the onomatopoeic sound generating device 10 When the manual operation switch button ₁₄ disposed in
The emergency alarm sound is generated by specifying the specific scale control data stored in 2. In general homes, this emergency alert sound is sufficiently effective if it is generated only in the toilet where the onomatopoeic sound generator 10 is installed, but in offices, companies, department stores, schools, stations, etc.
In large-scale facilities, it is also possible to provide direct access not only to the restrooms but also to security stations, staff rooms, etc. In addition, in hospitals, it is possible to have direct access to the nurse's station. In the present invention, a manual operation switch button 13 as a substitute for the sensor 8 is arranged on the front surface 10b of the container 10a, while a manual operation switch button 14 for emergency notification is arranged on the side surface 10c of the container 10a. Therefore, the toilet user U does not have to press the wrong switch button, and can casually press the switch buttons when a woman or woman is attacked by a thug.

Since the present invention is constructed and operates as described above, when the user opens the door of the flush toilet, the light intensity inside the toilet changes, and the light intensity reaction sensor senses this change in light intensity, thereby producing an onomatopoeic sound generating device. It operates for a certain period of time and continuously generates a sound similar to the sound of running water, for example, so toilet users do not have to flush water just to eliminate the sound of defecation. The effect is that the usage amount can be significantly reduced. In addition, when it is desired to flush water to actually flush away excrement, the water can be flushed at any time as before, so that the toilet user does not feel strange or inconvenienced. In addition, by providing a simple and compact onomatopoeic sound generator and equipping it with an emergency alarm function for crime prevention or emergency relief, it is possible to prevent crimes and accidents in the toilet beforehand, making it practical. This is an extremely valuable invention.
