A comparator 15 which collects excretion sound directly or indirectly by a microphone 5 and compares a signal level in a predetermined frequency range collected by the microphone 5 with a preset reference level indicating an excretion state. And at least an onomatopoeia is generated by the output of the comparator 15.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an onomatopoeia generator that automatically generates an onomatopoeia to drown out excretion sounds when using a toilet bowl.

[0002]

[Prior art]

 Toilet users often use the excretion sound generated when using the toilet bowl by mixing it with the outflow sound of the wash water, but such a method causes wasteful water to be drained to that extent, which is not preferable. Absent. For this reason, an onomatopoeia generator that produces an onomatopoeia similar to the outflow sound of the wash water may be provided. Further, in the conventional onomatopoeia generation device, the switch for producing the onomatopoeia is either an automatic switching system in which an infrared sensor or the like detects by holding a hand, or a manual type in which a push button is pressed.

[0003]

[Problems to be solved by the device]

 However, with the former automatic switching method, which was configured to automatically generate artificial sounds after a predetermined time when it entered the toilet room, the timing with defecation may shift, and the system may not be able to defecate again. In some cases, the switch of the artificial sound generating device had to be manually operated. Also, in this system, the onomatopoeic sound generation time for one switch operation is fixed, so if the onomatopoeic sound generation time elapses during excretion, the extension operation is required. The onomatopoeia generation mechanism by the switch must be installed in parallel and does not function as a completely automatic switching.

[0004]

[Means for Solving the Problems]

 The automatic onomatopoeia generator according to claim 1 according to the present invention compares a microphone that collects excretion sound with a signal level in a predetermined frequency range collected by the microphone and a preset reference level. And an onomatopoeia generation circuit that is operable according to the comparison result of the comparator.

According to a second aspect of the present invention, there is provided an automatic onomatopoeia generation device, which is provided with a logic circuit for performing a logical product of the comparator and the predetermined state confirmation sensor in the device according to the first aspect. Is a device in which the above-mentioned onomatopoeia generation circuit is operated.

According to a third aspect of the present invention, the automatic onomatopoeia generation device is a device according to the second aspect, wherein the state confirmation sensor is a seating detection sensor and a washing handle state detection sensor.

[0007]

[Action]

 The excretion sound is detected by a microphone installed in the toilet bowl, a signal in a predetermined frequency region is extracted from the detected sound, and the extracted signal components are averaged to form an excretion sound voltage. Then, the excretion sound voltage is compared with a preset reference voltage in a comparator. When the excretion sound voltage is higher than the reference voltage, it is determined that excretion is in progress, and an artificial sound similar to the outflow sound of wash water is generated. At this time, in order to prevent the generation of unnecessary pseudo-noise, the states of a predetermined state confirmation sensor, for example, the seating detection sensor and the state detection sensor of the cleaning handle are simultaneously confirmed to generate the pseudo-noise.

【Example】

 An embodiment of an automatic onomatopoeia generating device according to the present invention will be described below with reference to the drawings. FIG. 1 is a partial perspective view showing a toilet room 1 in which an automatic onomatopoeia generator according to the present invention is installed. The automatic onomatopoeia generator is composed of an onomatopoeia generation section 4 in which a speaker 2 as a source of the onomatopoeia and a circuit block 3 for driving the speaker 2 are integrally formed, and a microphone 5 for collecting excretion sounds. (See FIG. 2).

The shape of the onomatopoeia generation part 4 is composed of a hook-shaped urethane resin body 8 attached to the central part 7 on the back side of the body of the toilet bowl 6, and the back wall of the toilet room 1 on the back side of the urethane resin body 8. The speaker 2 is attached at a position facing the speaker 9. To attach the urethane resin body 8 to the body of the toilet 6, for example, an epoxy resin agent is used. If the speaker 2 is waterproof, it is preferable for use in the humid toilet room 1 and is convenient for cleaning.

The microphone 5 is unidirectional, and is fixed to, for example, the toilet seat 11 within a range that does not interfere with the use of the toilet 6, and collects sound toward the trap reservoir 10 inside the toilet 6. It is made possible.

FIG. 2 shows a specific configuration example of the circuit block 3. In FIG. 2, the sound collected by the microphone 5 is broad-band amplified by the amplifier 12, and the filter 13 extracts only the sound in a predetermined frequency range. Here, the sound collected by the microphone 5 is, for example, not only the excretion sound itself but also the jumping sound in the trap reservoir 10 corresponding to the sound of indirect excretion, and by the installation of the filter 13, Although it depends on the person and the sex, it is possible to detect a signal in a region peculiar to excretion sounds.

The signal in the predetermined frequency region that has passed through the filter 13 is averaged by the averaging circuit 14 to become the excretion sound voltage which is a signal for detecting the time of excretion. The excretion sound voltage is compared with a preset reference voltage 16 in the comparator 15. Then, when the excretion sound voltage is higher than the reference voltage, the artificial sound generating circuit 20 is made operable. Further, in this example, a seating detection sensor 17 and a washing handle state detection sensor 18 are provided in order to prevent the generation of unnecessary artificial sound, and the seating detection sensor 17 confirms the sitting state of the toilet user, Moreover, the artificial sound generating circuit 20 is activated only after the logical product circuit 19 detects that the cleaning handle is not activated.

In this example, the outputs of both the seating detection sensor 17 and the washing handle state detection sensor 18 are input to the AND circuit 19, but of course only one sensor output may be input. Further, for example, the output of another state detection sensor such as an illuminance sensor that detects entry into the toilet room 1 may be input.

However, in the automatic onomatopoeia generation device of this example, a signal in a predetermined frequency region is extracted from the excretion sound and the water splash sound collected by the microphone 5, and the extracted signal is used as the excretion sound signal. When the value exceeds a certain value, it is judged to be excreting, and the states of the seating sensor 17 and the state sensor 18 of the washing handle are checked to automatically generate a dummy sound without waste. Further, in this example, the speaker 2 which is the source of the onomatopoeia is attached to the main body of the toilet 6, and since the speaker 2 produces the onomatopoeia toward the wall surface in the toilet room 1, the onomatopoeia is also generated for the toilet user. Doesn't get jarring.

Further, although the present example is an apparatus for automatically generating onomatopoeia, a manual switch (not shown) for generating onomatopoeia may be provided together, and in this case, the speaker 2 is operated by this operation. It may be provided integrally or separately in the housing provided with the switch.

FIG. 3 is a view showing another embodiment. In this example, the circuit block 3 and the speaker 2 are housed in a housing 21 fixed to the wall surface of the toilet room 1, and in this case also. A manual switch may be provided in parallel with the housing 21 as in the above-described embodiment.

[0017]

[Effect of device]

 As described above, according to the present invention, since the onomatopoeia generator automatically detects the time of excretion, the troublesome operation of operating the switch of the onomatopoeia generator at the timing of defecation is unnecessary.
