Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an onomatopoeic sound generator, and more particularly to an onomatopoeic sound generator that is used to muffle the sound of defecation in a general flush toilet and can also be used as an alarm.

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. Another object of the present invention is to provide an alarm switch configured to generate an alarm sound by pressing a button several times in succession, and to stop the alarm sound by continuing to press the button for a predetermined period of time. Normally, even if you accidentally press the alarm switch, the alarm does not sound, and if there is an unexpected intruder such as a thug while you are using the toilet, or if there is any other emergency, press the alarm switch repeatedly to sound the alarm and alert the surrounding area. To improve the safety of an alarm device by notifying a person and making it impossible to easily stop the alarm sound unless the alarm switch is pressed for a predetermined period of time. Still another object is to provide a simple and compact onomatopoeia generator by electronically generating onomatopoeias.

In short, the present invention provides a digital-to-analog conversion device configured to output a voltage corresponding to a binary value in response to a binary input;
a storage device storing a plurality of binary voltage control data that determines the output voltage of the analog conversion device;
an onomatopoeia selection switch that selects a type of onomatopoeia; an onomatopoeia selection device that generates a selection signal according to the input type of the onomatopoeia selection switch and selects a specific group of voltage control data from the storage device; a temporary storage device that temporarily stores the address of each of the voltage control data thus selected; and a temporary storage device that operates in response to the selection signal and stores the address of the voltage control data selected from the storage device. an arithmetic device that sequentially reads voltage control data selected based on the program from the storage device at scheduled timing and inputs it to the digital-to-analog conversion device; The onomatopoeia selection device includes a speaker that outputs audio, an illuminance change detection device that includes a light sensor and generates an electric signal by detecting changes in surrounding illumination, and an alarm switch, and the onomatopoeia selection device receives electricity from the illuminance change detection device. When a signal is received, a selection signal determined by the onomatopoeia selection switch is generated and maintained for a certain period of time, and when a short pulse is received from the alarm switch more than a certain number of times consecutively at an interval of less than a certain time, an alarm sound is generated. The present invention is characterized in that the selection signal is generated preferentially, and the selection signal is maintained until a signal input for a certain period of time or more is received from the alarm switch.

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. Toilet wall surface 6 facing door 2
As shown in the figure, an illumination lamp 7 is attached to the upper part of the wall, and an onomatopoeic sound generator 1 is attached to the lower part of the wall.
0 is attached. The onomatopoeia generator is a second
As is clear from the figure and FIG. 3, the optical sensor 8
, an illuminance change detection device 19 , and an onomatopoeic selection device 20
, a central processing unit 21 , and an electronic fixed storage device 2
2, an electronic temporary storage device 23, a digital-to-analog conversion device 24, an audio amplification device 25, a speaker 9, an alarm switch _S0 , and onomatopoeic selection switches _S1 and _S2 . Illuminance change detection device 19
is configured so that the light sensor 8 provided on the front side of the onomatopoeic sound generating device 10 detects minute changes in the brightness received, that is, the illuminance inside the toilet 1, and generates an electric signal every time the illuminance changes. There is.

The onomatopoeic selection device 20 is configured to generate a selection signal when receiving an electrical signal from the illuminance change detection device 19 and when receiving an input from the alarm switch. In the former case, onomatopoeic selection switches S ₁ and S ₂
etc., a selection signal corresponding to a pre-selected onomatopoeic sound such as the sound of running water or a _babbling sound is generated and lasts for a certain period of time. When a plurality of short pulses are received a certain number of times (5 times in this embodiment) or more, an alarm is given priority regardless of the state of the onomatopoeic selection switches S ₁ and S ₂ and the presence or absence of the electrical signal of the illuminance change detection circuit 19. A sound selection signal is generated, and the selection signal is configured to last until a long input of a certain period of time (30 seconds in this embodiment) is received from the alarm switch _S0 .

The electronic fixed storage device 22 is a ROM (READ
ONLY MEMORY), and stores a plurality of binary voltage control data for generating onomatopoeia, that is, for determining the output voltage of the digital-to-analog converter 24. The central processing unit 21 selectively organizes the addresses of the voltage control data in the electronic permanent storage device 22 according to a predetermined program in response to the designated selection signal of the onomatopoeic selection device 20, and the electronic temporary storage device 23 is configured as a RAM. (RANDOM
ACCESS MEMORY), which temporarily stores the program contents. and central processing unit 2
1. The electronic fixed storage device 22 and the electronic temporary storage device 23 constitute a microcomputer.

The present invention is constructed as described above, and its operation will be explained below. As shown in Figure 1,
Lamp 7 when door 2 of toilet 1 is closed
The incident light A is reflected by the door 2 at a certain angle, and the reflected light A' shown by the imaginary line is detected by the optical sensor 8. Next, the toilet user enters door 2.
When opened, the light from the lamp 7 is reflected by the toilet user and becomes reflected light A'', so the sensor 8 detects the change in illuminance, the illuminance change detection device 19 generates an electric signal, and the onomatopoeic selection device 20 is operated, and the onomatopoeic selection device generates a preselected selection signal.The central processing unit 21 receives the selection signal and operates, and stores the electronic fixed storage device 2 in accordance with a predetermined program.
2 selectively organizes the addresses of the voltage control data of 2, and stores the program contents in the electronic temporary storage device 2.
3 to be temporarily stored. Based on this program, the central processing unit 21 transmits the voltage control data from the electronic fixed storage device 22 to a transmitter, etc. (not shown).
Read out continuously at the timing of The digital-to-analog converter 24 receives and converts these binary voltage control data into voltage, the audio amplifier 25 amplifies this, and the speaker 9 outputs it as an onomatopoeic sound of the scheduled scale. After a certain period of time has elapsed, the expected potential of the onomatopoeia generator 10 disappears, and the onomatopoeia generation operation stops. However, the need for further onomatopoeic generation may arise. In this case, if the toilet user U makes some movement such as slightly shifting his or her body or moving his/her hand, 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 movements to generate onomatopoeia.

Next, the operation when the onomatopoeia generator 10 is used as an alarm will be explained. Alarm switch S ₀
is located in an easy-to-operate position on the front of the onomatopoeic sound generator 10, so there is a high possibility that it will be pressed by mistake.
Even if a single push button operation or a plurality of button operations are performed, if the time interval between the operations is wide, the alarm sound selection signal of the onomatopoeic sound selection device 20 is not generated, thereby preventing the alarm from being erroneously issued. If there is an unexpected intruder such as a thug while using the toilet, the toilet user U can generate an alarm by continuously pressing the alarm switch _S0 as shown in FIG. FIG. 5 is a time chart showing the relationship between the operation of the alarm switch and the sound generated by the onomatopoeia generator 10.
The three broken lines L, M, and N indicate the output status of the alarm switch, alarm sound, and onomatopoeia, respectively. The upper line of each line indicates the ON state, the lower line indicates the OFF state, and the horizontal axis represents the time t. represents the progress of Now, when the toilet user U moves his arm as shown in Figure 4 to press the alarm switch _S0 at time a, the optical sensor 8 responds to the change in illuminance and an onomatopoeic sound is generated (the polygonal line N moves to the upper stage). . User U turns alarm switch S ₀ at time a
The two presses from to time b are onomatopoeic selection device 2.
However, since there is a gap of 1 second or more between time b and time c, the _two inputs are canceled and counting is restarted from time c. Alarm switch S ₀ from time c
If you press the button continuously at such a speed that the time t ₂ between press button operations is less than 1 second, an alarm sound will be generated for the fifth time and the onomatopoeia will stop (the polygonal line M will move to the upper row, and the polygonal line L will move to the lower row). ). If left in this state, the alarm will continue to sound. To stop the alarm, it is necessary to hold down the alarm switch _S0 for a predetermined period of time. If the alarm switch S ₀ is kept pressed from time e, the alarm sound will stop after 30 seconds, and then at time g the alarm switch S ₀ will be turned OFF.
In this way, the device of the present invention cannot stop the alarm sound unless a person knows how to use it in advance, and the alarm always continues for a predetermined period of time.
You can notify people around you of an emergency situation and disperse the thugs.

Since the present invention is configured and operates as described above, the user can hear onomatopoeia for a certain period of time simply 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. In addition, we have an alarm switch that generates an alarm by pressing a button several times in succession, and stops it by holding down the button for a predetermined period of time. If this does not occur and there is an unexpected intruder such as a thug while you are using the toilet, or if there is any other emergency, you can press the alarm switch repeatedly to sound the alarm and notify people around you. Since only a person who knows how to use the invented device can stop the alarm sound, the effect of high safety can be obtained. Furthermore, since the onomatopoeic sounds are 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.
