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.

Generally, the amount of water used 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 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 disadvantage was that precious water was 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 one 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 flush toilet when the toilet user opens the door of the flush toilet. A light-responsive sensor detects changes in light intensity and operates an onomatopoeic sound generator for a certain period of time to continuously generate a sound similar to the sound of running water, allowing toilet users to simply muffle the sound of defecation. The aim 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 use rC so that when the user really wants to flush water to flush away excrement, the water can be flushed at any time as before, so that the user does not feel strange or inconvenienced. . Another object of the present invention is to provide a simple and compact onomatopoeia generator by electronically generating onomatopoeias.

In short, the present invention provides an electronic storage device for storing binary scale control data for generating a plurality of series of sounds in a flush toilet that drains water and purifies the toilet bowl by operating a manual lever in one direction. an electronic temporary storage device for selectively temporarily storing a program signal having said scale control data; A scale selection device that selects a specific group of data and a scale selection device that operates in response to a selection signal from the scale selection device, and programs the scale control data of the storage device W1 in the temporary storage device; an arithmetic unit that sequentially reads scale control data selected from the storage device at a scheduled timing based on the data; a digital-to-analog conversion device that converts the read-out scale control data into voltage; and the digital-to-analog conversion device. The toilet is characterized by comprising a speaker that outputs the output as a scale, and a light intensity 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. It is something.

The present invention will be explained below based on embodiments shown in the drawings. 1st
In the figure, the 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 corpse water storage tank to flush away excrement. An illumination lamp 7 is attached as shown in the upper part of the wall 6 of the toilet facing the door 2, and an onomatopoeic sound generator 10 is attached to the lower part of the wall. As is clear from FIGS. 3 and 4, the onomatopoeic sound generating device includes a photoresponse sensor 8, a scale selection device 20, a central processing unit 7;f121, an electronic identification memory value [22], and an electronic temporary It includes a storage device 23, a digital-to-analog converter 24, and a speaker 9, and is connected to a power source 12 by a cord 11, as shown in FIGS. 1 and 2. The scale selection device 20 has a plurality of scale selection signals, which are selectively selected by operating selection switches S, S, . . . a specific to each scale signal. Various onomatopoeic scales can be selected at will, such as the sound of running water, the sound of a babbling stream, and the chirping of birds. Electronic fixed storage device 22 ROM (READ)
0NLY MEMORY), and stores a plurality of binary scale control data for generating onomatopoeia. The central processing unit 21 receives the specified scale selection signal from the scale selection device 20 and stores the electronic fixed storage device 22 in accordance with the scheduled program.
selectively generates the scale control data of
88 MBMORY) and temporarily stores the program answer. and central processing unit 21. An electronic identification storage value #22 and an electronic temporary storage device 23 constitute a microcomputer. As shown in FIG. 1, when the door 2 of the toilet 1 is closed f', the person entering the lamp 7 is reflected by the door 2 at a constant angle, and the reflected light A' shown by the imaginary line is light. It is designed to be detected by the heavy reaction sensor 8. 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 X, so the sensor 8 detects the change in the luminous intensity, and
The device is operated by maintaining o at a predetermined potential for a predetermined time. 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 the 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 the toilet user U opens the door 2, the light ray AA' of the lamp 7 changes from A- to ', and the sensor 8 detects the change in luminous intensity to reach the expected potential, and the scale selection device 20 is operated, and the scale selection signal generates a scale selection signal which is selected in advance.The central processing unit 121 receives the scale selection signal and operates, and automatically fixes the scale according to the scheduled program. The scale control data in the storage device 22 is selectively organized and the program contents are temporarily stored in the electronic temporary storage 1f [23].Then, based on this program, the central processing unit 21 is stored in the fixed storage device [23]. 22 to transmit the scale control data to a transmitter, etc. (not shown)
Read out continuously at the timing of The digital-to-analog converter 24 receives these binary scale control data, converts them into voltage, amplifies the data, and outputs the same from the speaker 9 as an onomatopoeia of the planned scale. After a certain period of time [... has elapsed, the expected potential of this onomatopoeic sound generating device 10 disappears and the onomatopoeic sound generating operation stops. In FIG. 2, the state of the light A-4 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, the need for further onomatopoeic generation may arise. In this case, if the toilet user U makes some movement such as sliding his body or moving his hand, the toilet user U will sense the change in the luminous intensity inside the toilet and maintain the expected potential again. , an onomatopoeic sound generator 1 (operates to generate an onomatopoeic sound. The relationship between the light emitting body and the photoresponse sensor 8 is limited by the size of the place where the sensor is used, but it can be used in a typical private toilet. The customer volume of 1 is the sensor 8 for changes in luminous intensity or brightness.
It is clear that this reaction is sufficiently protected.

As described above, in the uninvented onomatopoeic sound generating device, an onomatopoeic sound, for example the sound of running water, is generated when the door of the flush toilet is opened, so the toilet user U/1'i simply uses water to muffle the sound of defecation. I realized that there is no need to flush water, so I don't waste water.

Next, when excrement is formed and it is necessary to flush 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 (J) moves his body, the luminous intensity inside the toys t and 1 changes, and onomatopoeic sounds occur, but this does not make any difference.

Furthermore, Figure 2 shows a Western-style flush toilet with a water storage tank, but this book does not necessarily have to be a water tank type book, and it is of course possible to use a Japanese-style toilet as well. When using the toilet 1, the user U opens the door 2 and the movement of the toilet user changes the luminous intensity or brightness inside the toilet.

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, when a toilet user opens the door of a flush toilet and enters the toilet, an onomatopoeic sound, such as the sound of running water or other sounds, continues for a certain period of time. Therefore, if the user simply wants to muffle the sound of excretion, there is no need to flush the water, resulting in the effect of significantly reducing the amount of water used in flush toilets. Also, there is no need to operate any specific parts other than the toilet door to generate onomatopoeic sounds.
Even if the user does not know that it is a flush toilet with an onomatopoeic sound generator, the sound of running water will be heard when the door is opened! By generating onomatopoeic sounds, the user learns that there is no need to waste water, and after a while, the user becomes more thorough in using this type of toilet.

Furthermore, if you really want to flush out the excrement, you can flush the water at any time as before, so you can use it as per the usage amount, and it has the advantage of not feeling strange or inconvenient.
Since the VcM sound is generated without using a tape recorder, it is possible to provide a simple and compact onomatopoeia generation second 1#, which is an invention with extremely high practical value.
