Japanese Patent No. 4194817 JP 2009-125502 A

  In the toilet seat device of Patent Literature 2, since the through hole for generating sound is not required in the double lid structure, it is possible to prevent scattered water droplets and the like from entering the double lid structure. However, in order to dispose the vibrating speaker in the double lid structure toilet lid, it is necessary to not only prepare a dedicated toilet lid but also to configure the wiring for the vibration speaker to pass through a support shaft supporting the toilet lid. . For this reason, the toilet lid and the support structure are complicated, which leads to an increase in cost.

  An object of the present invention is to provide a vibration speaker in a toilet seat device with a simple configuration that does not require a dedicated configuration.

  The toilet seat device of the present invention employs the following means in order to achieve the above-mentioned main object.

  The toilet seat device of the present invention is a toilet seat device including a main body fixed to a toilet and a toilet seat supported by the main body, and is disposed in a hollow portion in the main body or a hollow portion in the toilet seat, The gist of the present invention is to provide a vibration speaker that generates sound by vibrating the main body or the toilet seat.

  The toilet seat device of the present invention includes a vibrating speaker that is disposed in a hollow portion in a main body or a hollow portion in a toilet seat and that generates sound by vibrating the main body or the toilet seat. Thus, a vibrating speaker can be provided in the toilet seat device with a simple configuration without using a double lid structure for the toilet lid. Further, since water droplets do not easily enter into the main body or the toilet seat, it is possible to prevent water droplets from being applied to the vibration speaker. Also, by disposing the vibrating speaker in the hollow portion of the main body or the hollow portion of the toilet seat, the sound generated by the vibration is diffused while being reflected on the inner surface of the hollow portion and is emitted to the outside. The sound effect can be improved by increasing the sense of spread of the sound.

  In the toilet seat device of the present invention, the toilet seat is supported by the main body by a hollow support shaft, is supplied with electric power by wiring passing through the support shaft, and is disposed on a back surface of a seating surface of the toilet seat. The vibration speaker may include a heater, the vibration speaker may be disposed on a bottom surface facing the back surface in a hollow portion in the toilet seat, and may be supplied with power by a wiring passing through the support shaft. In this case, since the wiring of the vibrating speaker can be passed through the support shaft through which the wiring of the toilet seat heater is passed, the vibrating speaker can be provided in the toilet seat device including the toilet seat heater without largely changing the structure. .

  In the toilet seat device of the present invention, the vibrating speaker may be disposed on a rear side of the hollow portion in the toilet seat. Thereby, the sound of the vibrating speaker can be generated closer to the buttocks where the user's excretion sound is generated, so that the excretion sound can be canceled more effectively.

  In the toilet seat device of the present invention, the vibrating speaker may be disposed in a hollow portion in the toilet seat, and vibrate the toilet seat at a frequency different from that at which sound is generated. In this way, information can be transmitted to the user sitting on the toilet seat by using the vibration from the vibration speaker.

  Next, an embodiment for carrying out the present invention will be described.

  FIG. 1 is an external perspective view of a toilet 1 to which a toilet seat device 10 of the present embodiment is attached, FIG. 2 is a schematic configuration diagram of the toilet seat device 10, and FIG. FIG. 3 corresponds to the AA cross section in FIG. The toilet 1 is a Western-style toilet, and a toilet seat device 10 is installed on an upper surface of the toilet 1. As shown in FIG. 1, the toilet seat device 10 includes a toilet seat device main body 11 fixed behind the toilet 1, a toilet seat 12 and a toilet lid 16 rotatably supported with respect to the toilet seat device main body 11, and a toilet seat 12. It includes a toilet seat heater 14 and a vibrating speaker 20 disposed therein, and an operation panel 18 operated by a user.

  The toilet seat device main body 11 includes a local cleaning device (not shown) including a heat exchange unit that heats the cleaning water, an injection nozzle that injects the cleaning water to a local part of the human body, and a control device 19 that controls the entire toilet seat device 10. These are accommodated in a resin housing.

  The toilet seat 12 is rotatably supported by the toilet seat device main body 11 through a hollow support shaft (rotating shaft) 13, and generates a toilet seat heater 14 for heating the seating surface 12 a and a dummy sound (sound). A vibration speaker 20 for generating the vibration is provided. The toilet seat 12 has a hermetically sealed structure so that water droplets do not enter the inside, and the toilet seat heater 14 and the vibrating speaker 20 are disposed in a hollow portion 12 b inside the toilet seat 12.

  Although not shown in detail, the toilet seat heater 14 is configured by sandwiching a meandering heater wire between two upper and lower metal foils, and the upper metal foil is provided on the seating surface 12a. It is attached to the toilet seat 12 by being attached to the back surface 12c on the back side. The heater wire of the toilet seat heater 14 is connected to a wiring 14 a for supplying electric power through the hollow support shaft 13. The toilet seat heater 14 has a metal foil formed along the shape of the seating surface 12 a of the toilet seat 12, but is interrupted at a central portion on the front side of the toilet seat 12, and has a central portion on the front side of the toilet seat 12. Not installed. This is because the central portion on the front side of the toilet seat 12 does not need to heat the seating surface 12a because the body (foot) of the user normally sitting on the toilet seat 12 does not contact.

  The vibrating speaker 20 is for generating an onomatopoeic sound such as a running water sound or a bird squeal to mask the excretion sound when the user excretes. The vibrating speaker 20 is disposed in the hollow portion 12b of the toilet seat 12 on the bottom surface 12d facing the back surface 12c. Further, a vibration speaker 20 is disposed behind the toilet seat 12 in the annular hollow portion 12 b of the toilet seat 12. Therefore, the vibration speaker 20 is located closer to the buttocks of the user sitting on the toilet seat 12. The vibrating speaker 20 has a vibrating element, and transmits a vibration of the vibrating element to the bottom surface 12 d of the toilet seat 12 based on a voice signal input from the control device 19 to vibrate the toilet seat 12 to generate a dummy sound. As the vibration element, for example, in addition to an electromagnetic actuator, a piezoelectric element or a giant magnetostrictive element is used.

  The control device 19 includes a CPU, a ROM, a RAM, and an input / output port (not shown). The control device 19 receives, via an input port (not shown), a detection signal from a seating sensor 17 for detecting the user's seating on the toilet seat 12, an operation signal from each operation switch provided on the operation panel 18, and a toilet seat 12. The temperature detected from a temperature sensor (not shown) that detects the temperature in the vicinity of the seating surface 12a is input. The operation panel 18 includes, for example, a cleaning operation switch 18a for starting a cleaning operation by the local cleaning device, a cleaning stop switch 18b for stopping the cleaning operation, a dummy sound generation switch 18c for starting generation of a dummy sound by the vibrating speaker 20, and a dummy sound. An operation switch such as an on-sound stop switch 18d for stopping the occurrence of the sound is provided. Further, the control device 19 outputs an operation signal to the local cleaning device, an operation signal to the toilet seat heater 14, an operation signal to the vibration speaker 20, and the like via an output port.

  In the toilet seat device 10 configured as described above, the operation related to the generation of the onomatopoeic sound using the vibration speaker 20 is performed as follows. For example, the control device 19 activates the vibration speaker 20 when the on-sound generation switch 18c of the operation panel 18 is operated, and starts generating on-sound by vibrating the toilet seat 12. At this time, based on the detection signal from the seating sensor 17, the control device 19 may use the fact that the user's seating is detected as the operating condition of the vibration speaker 20. Alternatively, the toilet seat apparatus 10 has an automatic onomatopoeic mode for automatically generating an onomatopoeic sound, in which the control device 19 starts the operation of the vibration speaker 20 when the user's seating is detected. It may be. Further, when the control device 19 determines that the on-sound stop switch 18d of the operation panel 18 has been operated during the operation of the vibration speaker 20, the operation of the vibration speaker 20 is stopped. In addition, in a case where the detection of the user's sitting is set as the operating condition of the vibration speaker 20, the control device 19 may stop the operation of the vibration speaker 20 when the user's sitting is no longer detected. .

  Here, the vibrating speaker 20 generates an imitation sound by vibrating the toilet seat 12 as a vibrating body. Since the vibrating speaker 20 is provided on the bottom surface 12d of the hollow portion 12b in the toilet seat 12, the sound generated by the vibration is diffused while being reflected on the inner surface of the hollow portion 12b and emitted to the outside. Become. For this reason, it is possible to enhance the sense of sound spread, and it is possible to improve the sound effect even when the relatively small vibration speaker 20 is used. Further, as described above, since the vibrating speaker 20 is disposed closer to the buttocks of the user, an imitation sound can be generated near the place where the excretion sound is generated, so that the excretion sound is effectively masked. be able to.

  In the toilet seat device 10 of the present embodiment described above, since the vibration speaker 20 is disposed in the hollow portion 12b inside the toilet seat 12, the vibration speaker 20 can be configured with a simple configuration without using the toilet lid 16 as a dedicated configuration. Can be arranged. Further, since the toilet seat 12 has a closed structure and water droplets do not easily enter, it is possible to prevent water droplets from splashing on the vibration speaker 20. In addition, by arranging the vibration speaker 20 in the hollow portion 12b, it is possible to enhance the sense of sound spread and improve the sound effect.

  Further, since the wiring 20a of the vibrating speaker 20 passes through the hollow support shaft 13 through which the wiring 14a of the toilet seat heater 14 passes, the vibration speaker 20 can be provided in the toilet seat device 10 including the toilet seat heater 14 without largely changing the structure. Can be.

  Further, since the vibrating speaker 20 is disposed on the rear side of the hollow portion 12b in the toilet seat 12, the excretion sound can be masked more effectively.

  In the present embodiment, the vibration speaker 20 is provided behind the toilet seat 12, but is not limited to this. FIG. 4 is an external perspective view of a modified toilet seat device 10B, and FIG. 5 is an external perspective view of a modified toilet seat device 10C. As shown in the toilet seat device 10B of FIG. 4, the vibration speaker 20 may be disposed at the center of the toilet seat 12 in the front-rear direction. In FIG. 4, the vibration speaker 20 is provided on the right side of the center of the toilet seat 12 when viewed from the seated user. However, the vibration speaker 20 may be provided on the left side of the center of the toilet seat 12. . Further, as shown in the toilet seat device 10C of FIG. 5, the vibration speaker 20 may be provided in front of the toilet seat 12. As described above, the toilet seat heater 14 is interrupted at the central portion on the front side of the toilet seat 12, and when the vibration speaker 20 is provided on the front side, it can be provided on the back surface 12c of the seating surface 12a. It becomes. For this reason, the degree of freedom of arrangement of the vibration speaker 20 can be increased.

  In the present embodiment, the vibration speaker 20 is provided in the hollow portion 12b in the toilet seat 12, but is not limited to this. FIG. 6 is an external perspective view of a modified toilet seat device 10D. As shown in the figure, a vibrating speaker 20 is provided in the toilet seat device main body 11 (housing) of the toilet seat device 10D. In this case, the vibration speaker 20 may be attached to the upper surface (ceiling surface) of the hollow portion in the toilet seat device main body 11. Since the hollow portion of the toilet seat device main body 11 is an internal space larger than the hollow portion 12a of the toilet seat 12, the sense of sound spreading can be further enhanced, and the acoustic effect can be further improved. Further, since it is not necessary to pass the wiring 20a of the vibration speaker 20 through the support shaft 13, the connection configuration can be simplified.

  In the present embodiment, the onset sound is generated by the vibration speaker 20. However, the present invention is not limited to this, and the toilet seat 12 may be vibrated at a frequency different from that at which the onset vibration speaker 20 generates the onset sound. For example, the vibration speaker 20 is operated so that the toilet seat 12 vibrates at a frequency of about 50 to 300 Hz. In this way, the vibration from the vibration speaker 20 can be used for transmitting information to the user sitting on the toilet seat 12. For example, when the user is seated on the toilet seat 12 for a predetermined time or more, by operating the vibration speaker 20, it is possible to inform the user that the user has been sitting for a predetermined time or more. Further, as the time during which the user is seated becomes longer, the use time of the toilet seat device 10 is increased by changing the mode of generation of vibration such as shortening the interval at which the vibration speaker 20 is operated. That can be communicated. In this way, when the toilet seat device 10 is for public use installed in a restaurant or a station, the user is alerted to long-term use, and promptly ends use. You can also.

  In the present embodiment, an example in which one vibrating speaker 20 is provided is exemplified. However, the present invention is not limited to this, and a plurality of vibrating speakers 20 may be provided. In this case, a plurality of vibrating speakers 20 are arranged on the same surface (such as the upper surface of a hollow portion in the toilet seat device main body 11). Further, for example, when two vibrating speakers 20 are mounted on the upper surface of the hollow portion in the toilet seat device main body 11, it is preferable that the two vibrating speakers 20 are arranged at a predetermined interval P in the lateral direction (left and right direction) of the toilet seat device main body 11. It is preferable that the predetermined interval P is substantially equal to or less than L / 4 when the lateral length of the toilet seat device main body 11 is L, whereby a stereo effect can be obtained. Also, if the predetermined interval P is wide and the position of each vibrating speaker 20 is close to both side walls, it is difficult to produce bass sound. If the predetermined interval P is too narrow and the position of each vibrating speaker 20 is too close, the stereo effect is reduced. P is more preferably close to L / 4.

[Another embodiment]
Next, a toilet seat device 100 according to another embodiment will be described. In the above-described embodiments and modifications, the vibration speaker 20 is provided in the toilet seat device main body 11 or the toilet seat 12, but in another embodiment, the vibration speaker 20 is provided in the toilet lid. FIG. 7 is an external perspective view of the toilet 1 to which the toilet seat device 100 of another embodiment is attached, and FIG. 8 is a schematic configuration diagram of the toilet seat device 100. In the toilet seat device 100, the same components as those of the toilet seat device 10 are denoted by the same reference numerals, and detailed description is omitted.

  The toilet seat 112 of the toilet seat device 100 is rotatably supported by the toilet seat device main body 11 via a hollow support shaft 13 similarly to the toilet seat 12, and the toilet seat heater 14 is provided. Is not provided. Further, the toilet seat heater 14 is interrupted at the central portion on the front side of the toilet seat 12 as in the above-described embodiment, and is not provided at the central portion on the front side. In the toilet seat 112, a power supply coil 121 is disposed in a hollow portion at a central portion on the front side where the toilet seat heater 14 is not disposed. The power supply coil 121 is energized through a wiring 121 a passing through the hollow support shaft 13.

  The toilet lid 116 of the toilet seat device 100 is supported by the toilet seat device main body 11 (toilet seat 112) via a support shaft 116a so as to be openable and closable. In another embodiment, the toilet lid 116 is configured to have an inner space as a double lid structure. Inside the toilet lid 116, a vibration speaker 120, a power receiving coil 123, a charging unit 124, a battery 125, and a speaker control device 127 are provided.

  The power receiving coil 123 is disposed at a position facing the power supply coil 121 of the toilet seat 112 in a closed state in which the toilet lid 116 covers the toilet seat 112. Therefore, in the closed state of the toilet lid 116, an electromagnetic induction wireless power supply in which a current flows in the power receiving coil 123 by applying a current to the power feeding coil 121 to change the magnetic flux of the power receiving coil 123 to generate an electromotive force. It is possible. Alternatively, wireless power feeding may be performed by another method, such as a magnetic field resonance method in which a current is caused to flow through the power receiving coil 123 by transmitting vibration to the power receiving coil 123 by causing vibration of a magnetic field generated by flowing a current through the power feeding coil 121 to cause resonance. . As described above, in the toilet seat device 100, wireless power supply can be performed by the power supply coil 121 and the power receiving coil 123, and wireless power supply conforming to the Qi standard is performed as an example.

  The charging unit 124 charges the battery 125 by rectifying the AC power from the power receiving coil 123 into DC power. The speaker control device 127 controls the vibration speaker 120 so that the vibration speaker 120 operates using the power of the battery 125. The speaker control device 127 also performs control and communication necessary for wireless power supply conforming to the Qi standard, and transmits various data necessary for power supply to the control device by wireless communication via the power receiving coil 123 and the power supply coil 121. Send to 19.

  In the toilet seat device 100 configured as described above, the operation related to the generation of the onomatopoeic sound using the vibration speaker 120 is performed as follows. FIG. 9 is a flowchart illustrating an example of a power supply control routine, and FIG. 10 is a flowchart illustrating an example of a speaker operation control routine. The power supply control routine of FIG. 9 is executed by the control device 19. In this power supply control routine, the control device 19 determines whether or not the toilet lid 116 is in the closed state based on the connection state of the wireless communication of the toilet lid 116 with the speaker control device 127 (S100). In addition, the opening and closing detection sensor of the toilet lid 116 may be provided in the toilet seat apparatus main body 11, and the control device 19 may detect the closed state of the toilet lid 116 based on the detection signal. When the controller 19 determines that the toilet lid 116 is in the closed state, the controller 19 starts power supply to the power supply coil 121 to start wireless power supply (S110).

  Then, it waits to determine whether the charging of the battery 125 has been completed (S120) or whether the toilet lid 116 has been opened (S130). The control device 19 determines the completion of charging of the battery 125 and the open state of the toilet lid 116 by wireless communication with the above-described speaker control device 127. When the controller 19 determines that the charging of the battery 125 is completed in S120 or determines that the toilet lid 116 has been opened in S130, the controller 19 terminates the power supply to the power supply coil 121 to terminate wireless power supply. (S140), ends the power supply control routine.

  The speaker operation control routine of FIG. 10 is executed by the speaker control device 127. In the speaker operation control routine, the speaker control device 127 determines whether the toilet lid 116 is in the open state (S200). Note that the speaker control device 127 may detect the open state of the toilet lid 116 based on the fact that the supply of power to the power receiving coil 123 is stopped when the battery 125 is not fully charged. Alternatively, the speaker control device 127 may detect the open state of the toilet lid 116 based on the connection state of the wireless communication with the control device 19, or may provide an open / close detection sensor on the toilet lid 116 and provide a detection signal to the detection signal. The open state of the toilet lid 116 may be detected based on this.

  When the speaker control device 127 determines that the toilet lid 116 is in the open state, the speaker control device 127 outputs an audio signal to the vibration speaker 120 and starts generating a dummy sound (S210). For this reason, an imitation sound is generated from the toilet lid 116 (the vibrating speaker 120) based on the fact that the toilet lid 116 has changed from the closed state to the open state. Then, the speaker control device 127 determines whether the toilet lid 116 has been closed (S220). When determining that the toilet lid 116 is in the closed state, the speaker control device 127 stops the operation of the vibrating speaker 120 to terminate the generation of the dummy sound (S230), and ends the speaker operation control routine. As described above, the operation of the vibration speaker 120 starts based on the toilet lid 116 being changed from the closed state to the open state, and the operation of the vibration speaker 120 based on the toilet lid 116 being changed from the open state to the closed state. Is the end. The operation signal from the onset switch 18c and the off switch 18d may be transmitted from the control device 19 to the speaker control device 127 by wireless communication. Then, the speaker control device 127 may control the start or stop of the operation of the vibration speaker 120 based on the operation signal transmitted from the control device 19.

  The toilet seat device 100 described above supplies power (wirelessly) wirelessly (in a non-contact manner) by the power supply coil 121 disposed on the toilet seat 112 and the power receiving coil 123 disposed on the toilet lid 116 to generate an imitation sound from the vibration speaker 120. Can be generated. Further, a toilet seat heater 14 is provided on the toilet seat 112, and the wiring 121 a of the power feeding coil 121 may be passed using the support shaft 13 of the toilet seat 112. Therefore, the vibration speaker 120 can be attached to the toilet lid 116 without changing the structure so that the wiring passes through the support shaft 116a of the toilet lid 116.

  Further, since the speaker control device 127 operates the vibration speaker 120 in accordance with the opening and closing of the toilet lid 116, the speaker control device 127 generates an imitation sound in accordance with the use timing of the user, and suppresses wasteful consumption of power by the vibration speaker 120. be able to. In addition, since the power supply coil 121 is provided at the front center of the toilet seat 112 where the toilet seat heater 14 is not provided, it is possible to perform wireless power supply without hindering the heating of the toilet seat 112 by the toilet seat heater 14.
