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 to muffle excretion sounds in a plurality of general flush toilets. The present invention relates to an onomatopoeia generating device for centrally managing a plurality of flush toilets with the single control unit, provided in separate locations, each toilet having only an input section and an output section.

Generally, the amount of water consumed by a toilet user in a flush toilet, that is, the amount of water consumed by the toilet user to purify the toilet bowl by flushing the toilet bowl after use, should be approximately constant. However, in general households, as well as in offices, companies, schools, hospitals, public restrooms in train stations, etc. where people often come and go, toilet users are conscious of the presence of people around them and remove excrement to muffle the sounds 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 wasted in this way is enormous even in a single day, especially in offices, companies, department stores, schools, hospitals, and train stations that have many flush toilets. In public facilities, a large amount of water is wasted, and at the same time, costs increase accordingly.

The present invention has been made to eliminate the above-mentioned drawbacks of the prior art, and its purpose is, for example, when a toilet user opens the door of a flush toilet, the luminous intensity inside the toilet changes. A photoresponse 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, for example, water flowing, so that toilet users can 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 allow toilet users to flush the water any time they want to flush out excrement, as usual, without causing any discomfort or inconvenience to the toilet user. Still another object is to provide a simple and compact onomatopoeia generator by electronically generating onomatopoeias, and to centrally manage a single control unit for multiple flush toilets. This eliminates the need to install electronic devices in each toilet, and only requires installing the minimum necessary elements in each toilet, that is, a photoresponse sensor as an example of an input part and a speaker as an output part. The objective is to achieve simplified configuration, improved functional efficiency, and significant cost savings. Another purpose is to provide commercial 100V power in each toilet through the centralized control of the above control unit.
The purpose is to eliminate problems such as insulation, leakage, and electric shock in the toilet, and to reduce equipment costs by requiring a power source and only needing extremely low-voltage wiring.

In summary, the present invention provides binary scale control data for generating a plurality of series of sounds in relation to a plurality of flush toilets that flush water and purify the toilet bowl by operating a manual lever in one direction. an electronic storage device for selectively temporarily storing a program signal having the scale control data; and a temporary storage device selectively operated to generate a selection signal; a scale selection device that selects a specific group of scale control 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 in the storage device in the temporary storage device; a control unit that includes an arithmetic unit that sequentially reads scale control data selected from the storage device based on the data at a scheduled timing; and a digital-to-analog converter that converts the read scale control data into voltage. Provided in a separate location from the plurality of toilets, each of the toilets is configured to serve as an input unit for the control unit to sense changes in phenomena within the toilet and generate an electrical signal to enable the scale selection device. The present invention is characterized in that it is configured by providing an input device and, as an output section of the control section, a speaker that outputs the output of the digital-to-analog conversion device as a musical scale.

The present invention will be explained below based on embodiments shown in the drawings. First, the onomatopoeic sound generating device and its operating principle, which are the basis of the present invention, will be explained using reference examples shown in FIGS. 1 to 3. In FIG. It is normal to do so. Inside the toilet 1, there is a toilet bowl 4 equipped with a water storage tank 3, and after use, the toilet user U operates a manual lever 5 provided on the water storage tank to flush out excrement. At the top of the toilet wall 6 facing the door 2 is a lighting lamp 7 as shown in the figure.

In FIGS. 2 and 3, the onomatopoeia generator 10
A light intensity response sensor 8, which is an example of an input device of an input section, is disposed on the front surface 10b of the container 10a, and inside the container there is a scale selection device 20, a central processing unit 21, and an electronic fixed storage device. 22, an electronic temporary storage device 23, a digital-to-analog converter 24, and a speaker 9,
As shown in FIG.
It is connected to the power supply 12 inside. Scale selection device 2
0 has a plurality of scale selection signals, each of which has its own selection switch S ₁ , S ₂ ...Sn
By operating the , various onomatopoeic scales stored in the electronic fixed storage device 22, such as the sound of running water, the sound of a babbling stream, and the cry of birds, can be arbitrarily selected. The electronic fixed storage device 22 is
It is a ROM (READ ONLY MEMORY) and stores multiple 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), which 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 is starting to be perceived. Next, when the toilet user opens 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 generator 1
0 at a predetermined potential for a predetermined time to operate this device.

In addition, in FIGS. 1 and 2, a switch button 13 is provided on the front surface 10b of the container 10a of the onomatopoeic sound generator 10, and this switch button 13 does not turn on at night because the illumination lamp 7 is out, and the light intensity reaction sensor 8 If the switch button 13 does not work, the toilet user can press the switch button 13 to switch the scale selection device 2

When you operate this switch button 14 when you are attacked by someone, when you feel that you are in danger, when you suddenly get sick and want to call someone, or when a disabled elderly person wants someone's help, you can hear an electronic sound that alerts you to an emergency. This is so that it occurs.

The reference example of 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 becomes a predetermined potential to operate the scale selection device 20, and the scale selection device generates a preselected scale selection signal. The scale selection signal is sent to the central processing unit 21.
operates in response, selectively organizes the scale control data of the electronic fixed storage device 22 according to a scheduled program, 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 continuously reads scale control data from the electronic fixed storage device 22 at the timing of an oscillator (not shown). These binary scale control data are converted into digital/analog converter 2.
4 receives the signal, converts it into a voltage, amplifies it, and then outputs it as an onomatopoeic sound of the scheduled scale from the speaker 9.
After a certain period of time has elapsed, the expected potential of the onomatopoeic sound generating device 10 disappears, and the onomatopoeic sound generating 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. The relationship between the light emitter and the light intensity responsive sensor 8 is limited by the size of the place where the sensor 8 is used, but 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 clear that

FIG. 4 shows an embodiment of the present invention constructed based on the above reference example, and in this embodiment, the onomatopoeic sound generating device 10 of the present invention is rationally applied to a plurality of flush toilets. be. That is, in public facilities where people frequently come and go, such as offices, companies, department stores, hospitals, schools, and stations, a large number of flush toilets are installed, and the onomatopoeic sound generating device 10 including a control unit is installed in all of these large number of toilets. It would cost more to do so. The present invention was proposed to solve this problem.

The present embodiment will be described below using the same reference numerals for the same parts as those of the above-mentioned reference example. That is, in this embodiment, as shown in the figure, each of the plurality of flush toilets 1 includes a part of the onomatopoeic sound generating device 10, that is, a light intensity response sensor 8, which is an example of an input device of an input section, and a speaker (not shown). ), and the scale selection device 2
0, central processing unit 21, electronic fixed storage device 2
2. A combination of the electronic temporary storage device 23 and the digital-to-analog conversion device 24 is installed as a control unit 30 in a location separate from the plurality of toilets 1, and is connected to an AC power source AC, with a changeover switch S. All flush toilets 1 are now centrally managed. In this case, the light intensity response sensor 8 and speaker (not shown) in each toilet 1 are connected in parallel to the input of the scale selection device 20 of the control unit 30 and the output terminal of the digital-to-analog conversion device 24, respectively, by conductive wires 40. .

Note that the control unit 30 may be provided with the same number of digital-to-analog converters 24 as the plurality of toilets 1 and connected to the speakers (not shown) in the toilets, and in this case, the central processing unit of the control unit 30 Device 21
and each digital-to-analog converter 24 are connected to each other via a changeover switch (not shown). Further, the control unit 30 may be provided with a single digital-to-analog converter 24 and commonly connected to a speaker (not shown) in each toilet 1. In this case, a single digital-to-analog converter 24 The analog converter 24 and each speaker (not shown) are connected via respective changeover switches (not shown). The conductive wire 40 connecting the control unit 30 and the photoresponse sensor 8 and speaker (not shown) in each toilet 1 may be a low voltage (several volts) wire.

The present invention is configured as described above, and its operation will be explained below. In FIGS. 1 to 3 showing reference examples and FIG. 4 showing an embodiment of the present invention, when a toilet user U opens the door 2 of one of the toilets 1, the luminous intensity inside the toilet changes. A light intensity reaction sensor 8 senses the change in light intensity and generates an electrical signal. This signal is sent to the digital/analog device 24 corresponding to the toilet 1 in the control unit 30.
and the central processing unit 21 (not shown) or between the single digital/analog device 24 and the speaker 9 of the toilet 1 used (not shown) is closed. , the scale selection device 20 of the control section 30 is operated to generate a previously selected scale selection signal. The central processing unit 21 operates upon receiving the scale selection signal, selectively organizes the scale control data of the electronic fixed storage device 22 according to a scheduled program, and temporarily stores the program contents in the electronic temporary storage device 23. Make me remember. 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 a voltage, and amplifies it. Then, the output of the digital-to-analog converter is received by the speaker in the toilet 1 and outputted as a scheduled scale. After a certain period of time has elapsed, the scheduled potential of the onomatopoeia generator 10 disappears, the onomatopoeia generation operation stops, and at the same time, a changeover switch ( (not shown) or a single shared digital
A switch (not shown) between the analog conversion device 24 and the speaker 9 of the toilet 1 used is opened.

As is clear from the reference example in Figure 1 and its description, if it becomes necessary to generate an onomatopoeic sound, the toilet user U should make some kind of movement, such as slightly shifting a part of his body or moving his arm. For example, the light intensity reaction sensor 8 senses the resulting change in the light intensity inside the toilet and generates an electrical signal again, and the onomatopoeic sound is generated again through the same operation as described above. In this case, in other toilets 1 that are not used, the light intensity response sensor 8
Since the control unit 30 does not operate, each switch (not shown) between each digital-to-analog converter 24 corresponding to these toilets and the central processing unit 21 or each speaker of these toilets 1 and the control unit 30 and the shared digital-to-analog converter 24 (not shown)
remains open, so no onomatopoeia occurs. When several toilets are used at the same time, the same onomatopoeia occurs in the other toilets at the timing of the onomatopoeic sound of the first toilet used.

In this way, the onomatopoeia generator 10 is controlled by a single control unit 3.
By centrally controlling a plurality of flush toilets with 0, this onomatopoeic sound generating device 10 achieves simplified configuration, improved functional efficiency, and significant cost savings.
The installation of the toilet is extremely easy, and the conductor 40 between the control unit 30 and each toilet 1 usually only needs to be supplied with a current of several volts.
There is no need to worry about electric shock or fire caused by electrical leakage. Therefore, the electric wires used need only be extremely thin and have low insulation performance, wiring is extremely easy, and equipment costs can be reduced accordingly.

Note that changes in phenomena inside the toilet 1 include not only changes in luminous intensity, but also changes in various phenomena such as the opening and closing of the door itself, touching the manual lever 5 by the toilet user U, and changes in temperature. is not limited to the photoresponsive sensor 8.

Since the present invention is configured and operates as described above, for example, when a toilet user opens the door of a flush toilet, the luminous intensity inside the toilet changes, and the luminous intensity reaction sensor detects this luminous intensity change. The onomatopoeic sound generator is operated for a certain period of time to continuously generate a sound similar to, for example, water flowing, eliminating the need for toilet users to simply flush water to muffle the sound of defecation. As a result, the amount of water used in flush toilets can be significantly reduced. Also, when you really want to flush the excrement, you can flush the water at any time as before.
The effect is that the toilet user does not feel strange or inconvenienced. In addition to providing a simple and compact onomatopoeia generator, by centrally managing a single control unit for multiple flush toilets, there is no need to install electronic devices in each toilet, and each toilet has the minimum required amount. Since it is only necessary to install the following elements, that is, the photoresponse sensor as the input part and the speaker as the output part, the advantage is that the configuration can be simplified, the functions can be made more efficient, and costs can be significantly reduced. It will be done. In addition, due to the centralized control of the control unit mentioned above, each toilet does not require a commercial 100V power supply and only needs to be wired at an extremely low voltage.Therefore, there is no risk of electric shock or fire due to electrical leakage in the toilet, and the wiring This is an invention with extremely high practical value, as it requires only extremely thin wires, requires low insulation performance, and reduces equipment costs.
