Detailed Description
Next, embodiments of the present invention will be explained.
Fig. 1 is an external perspective view of a toilet 1 to which a toilet device 10 according to the present embodiment is attached, fig. 2 is a schematic configuration diagram of the toilet device 10, and fig. 3 is a sectional configuration diagram of a toilet seat 12. Fig. 3 corresponds to the section a-a in fig. 2. The toilet 1 is a flush toilet, and a toilet device 10 is provided on the upper surface of the toilet 1. As shown in fig. 1, the toilet seat apparatus 10 includes: a toilet device main body 11 fixed to the rear of the toilet 1; a toilet seat 12 and a toilet cover 16 rotatably supported with respect to the toilet seat apparatus body 11; a toilet seat heater 14 and a vibration speaker 20 disposed in the toilet seat 12; and an operation panel 18 operated by a user.
The toilet seat apparatus main body 11 includes a local washing apparatus including a heat exchange unit for heating washing water and a spray nozzle for spraying the washing water to a local part of a human body, and a control device 19, the control device 19 controls the entire toilet seat apparatus 10, and the local washing apparatus and the control device 19 are housed in a resin case.
The toilet seat 12 is rotatably supported by the toilet seat apparatus body 11 via a hollow support shaft (rotation shaft) 13, and a toilet seat heater 14 for heating the seating surface 12a and a vibration speaker 20 for generating an artificial sound are disposed. The toilet seat 12 has a sealed structure in which water droplets do not enter the toilet seat, and the toilet seat heater 14 and the vibration speaker 20 are disposed in the hollow portion 12b in the toilet seat 12.
Although not shown in detail, the toilet seat heater 14 is configured to be attached to the toilet seat 12 by sandwiching a heater wire arranged in a meandering manner between two upper and lower metal foils, and attaching the upper metal foil to the back surface 12c on the back side of the seating surface 12 a. A wire 14a for supplying power through the hollow support shaft 13 is connected to the heater wire of the toilet seat heater 14. The metal foil is formed along the shape of the seating surface 12a of the toilet seat 12, but is discontinuous at the center portion on the front side of the toilet seat 12, and the toilet seat heater 14 is not disposed at the center portion on the front side of the toilet seat 12. This is because the center portion on the front side of the toilet seat 12 is generally not in contact with the body (legs) of the user seated on the toilet seat 12, and the necessity of heating the seating surface 12a is low.
The vibration speaker 20 generates pseudo sounds such as a water sound and a bird sound, thereby masking a user's excretion sound and the like when excreting. The vibration speaker 20 is disposed on the bottom surface 12d facing the back surface 12c in the hollow portion 12b of the toilet seat 12. A vibration speaker 20 is disposed on the rear side of the toilet seat 12 in the annular hollow portion 12b of the toilet seat 12. Therefore, the vibration speaker 20 is located in the further vicinity of the buttocks of the user seated on the toilet seat 12. The vibration speaker 20 includes a vibration element, and generates an artificial sound by transmitting vibration of the vibration element to the bottom surface 12d of the toilet seat 12 based on an audio signal input from the control device 19 and vibrating the toilet seat 12. In addition, as the vibration element, for example, a piezoelectric element, a giant magnetostrictive element, or the like is used in addition to an electromagnetic actuator.
The control device 19 includes a CPU, ROM, RAM, input/output ports, and the like, which are not shown. A detection signal from a seating sensor 17 that detects that a user is seated on the toilet seat 12, an operation signal from each operation switch provided on the operation panel 18, a detection temperature from a temperature sensor, not shown, that detects a temperature in the vicinity of the seating surface 12a of the toilet seat 12, and the like are input to the control device 19 via an input port, not shown. The operation panel 18 is provided with operation switches such as a cleaning operation switch 18a for starting the cleaning operation of the private parts cleaning apparatus, a cleaning stop switch 18b for stopping the cleaning operation of the private parts cleaning apparatus by the cleaning stop switch 18b, an imitation sound generation switch 18c for generating an imitation sound by the vibration speaker 20, and an imitation sound stop switch 18d for stopping the generation of the imitation sound by the vibration speaker 20. The operation signal transmitted to the private parts washing apparatus, the operation signal transmitted to the toilet seat heater 14, the operation signal transmitted to the vibration speaker 20, and the like are output from the control device 19 via the output port.
In the toilet apparatus 10 configured as described above, the following operation is performed in relation to the pseudo sound generation using the vibration speaker 20. For example, when the pseudo sound generation switch 18c of the operation panel 18 is operated, the control device 19 starts the generation of pseudo sound by operating the vibration speaker 20 and vibrating the toilet seat 12. At this time, the control device 19 may detect that the user is seated as an operation condition of the vibration speaker 20 based on the detection signal from the seating sensor 17. Alternatively, the toilet seat device 10 may have an automatic sound-imitating mode for automatically producing an imitation sound, and the control device 19 may start the operation of the vibration speaker 20 when it is detected that the user is seated. When the control device 19 determines that the pseudo stop switch 18d of the operation panel 18 is operated while the vibration speaker 20 is operating, the operation of the vibration speaker 20 is stopped. When the seating of the user is detected as the operation condition of the vibration speaker 20, the control device 19 may stop the operation of the vibration speaker 20 when the seating of the user is not detected.
Here, the vibration speaker 20 vibrates the toilet seat 12 as a vibrating body to generate pseudo sound. Since the vibration speaker 20 is disposed on the bottom surface 12d of the hollow portion 12b in the toilet seat 12, sound generated by vibration is diffused and emitted to the outside while being reflected on the inner surface of the hollow portion 12 b. Therefore, since the sense of sound diffusion can be improved, the acoustic effect can be improved even when the relatively small vibration speaker 20 is used. Further, since the vibration speaker 20 is disposed in the further vicinity of the hip of the user as described above, an artificial sound can be generated in the vicinity of the portion where the excretion sound is generated, and thus the excretion sound can be effectively masked.
In the toilet seat device 10 of the present embodiment described above, since the vibration speaker 20 is disposed in the hollow portion 12b in the toilet seat 12, the vibration speaker 20 can be disposed with a simple configuration without requiring a dedicated configuration for the toilet cover 16. Further, since the toilet seat 12 has a sealed structure and water droplets hardly enter, the water droplets can be prevented from being suspended from the vibration speaker 20. Further, by disposing the vibration speaker 20 in the hollow portion 12b, the sense of diffusion of sound can be improved, and the acoustic effect can be improved.
Further, since the wiring 20a of the vibration speaker 20 is passed through the hollow support shaft 13 through which the wiring 14a of the toilet seat heater 14 is passed, the vibration speaker 20 can be disposed in the toilet seat device 10 including the toilet seat heater 14 without largely changing the configuration.
Further, since the vibration speaker 20 is disposed on the rear side of the hollow portion 12b in the toilet seat 12, the excretion sound can be further effectively masked.
In the present embodiment, the vibration speaker 20 is disposed on the rear side of the toilet seat 12, but is not limited thereto. Fig. 4 is an external perspective view of a toilet seat apparatus 10B according to a modification, and fig. 5 is an external perspective view of a toilet seat apparatus 10C according to a modification. As shown in the toilet seat device 10B of fig. 4, the vibration speaker 20 may be disposed at the center portion in the front-rear direction of the toilet seat 12. In fig. 4, the vibration speaker 20 is disposed on the right side of the center portion of the toilet seat 12 as viewed by the seated user, but the vibration speaker 20 may be disposed on the left side of the center portion of the toilet seat 12. As shown in the toilet seat device 10C of fig. 5, a vibration speaker 20 may be disposed on the front side of the toilet seat 12. Further, as described above, the toilet seat heater 14 may be provided intermittently at the center portion on the front side of the toilet seat 12, and may be disposed on the back surface 12c of the seating surface 12a when the vibration speaker 20 is disposed on the front side. Therefore, the degree of freedom in the arrangement of the vibration speaker 20 can be improved.
In the present embodiment, the vibration speaker 20 is disposed in the hollow portion 12b in the toilet seat 12, but is not limited thereto. Fig. 6 is an external perspective view of a toilet seat device 10D according to a modification. As shown in the drawing, a vibration speaker 20 is disposed in a toilet seat apparatus main body 11 (housing) of the toilet seat apparatus 10D. In this case, the vibration speaker 20 can be attached to the upper surface (top surface) of the hollow portion in the seat device main body 11. The hollow portion of the toilet seat device body 11 is an internal space larger than the hollow portion 12a of the toilet seat 12, and the sound diffusion feeling can be further improved, thereby further improving the acoustic effect. Further, since it is not necessary to pass the wiring 20a of the vibration speaker 20 through the support shaft 13, the connection structure can be made simpler.
In the present embodiment, the pseudo sound is generated by the vibration speaker 20, but the present invention is not limited to this, and the vibration speaker 20 may vibrate the toilet seat 12 at a frequency different from that at the time of the pseudo sound generation. For example, the vibration speaker 20 is operated so that the 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 to transmit information to the user seated on the toilet seat 12. For example, when the user is seated on the toilet seat 12 for a predetermined time or more, the vibration speaker 20 is activated, whereby information that the user is seated for the predetermined time or more can be transmitted to the user. Further, by changing the generation mode of the vibration such as shortening the interval at which the vibration speaker 20 is operated as the time for which the user sits on the seat becomes longer, information that the use time of the toilet apparatus 10 becomes longer can be transmitted to the user. In this way, even when the toilet apparatus 10 is installed in a public structure such as a restaurant station, the user can be made aware of long-term use, and early termination of use can be promoted.
In the present embodiment, one vibration speaker 20 is provided as an example, but the present invention is not limited to this, and a plurality of vibration speakers 20 may be provided. In this case, the plurality of vibration speakers 20 are arranged on the same surface (upper surface of the hollow portion in the toilet seat apparatus main body 11, etc.) or the like. For example, when two vibration speakers 20 are attached to the upper surface of the hollow portion in the toilet seat apparatus main body 11, they are preferably arranged with a predetermined interval P in the lateral direction (left-right direction) of the toilet seat apparatus main body 11. When the lateral length of the toilet seat apparatus body 11 is L, the predetermined interval P is preferably substantially L/4 or less, whereby a stereo effect can be obtained. Further, the predetermined interval P is more preferably close to L/4 because it is difficult to generate bass sound when the predetermined interval P is wide and the positions of the vibration speakers 20 are close to both side walls, and because the stereophonic effect is reduced when the predetermined interval P is narrow and the positions of the vibration speakers 20 are too close to each other.
[ other embodiments ]
Next, a toilet seat apparatus 100 according to another embodiment will be described. In the above-described embodiment and modification, the vibration speaker 20 is disposed in the toilet seat apparatus main body 11 or the toilet seat 12, but in another embodiment, the vibration speaker 20 is disposed in the toilet cover. Fig. 7 is an external perspective view of the toilet 1 to which the toilet apparatus 100 according to another embodiment is attached, and fig. 8 is a schematic configuration diagram of the toilet apparatus 100. In the toilet seat apparatus 100, the same components as those of the toilet seat apparatus 10 are denoted by the same reference numerals, and detailed description thereof is omitted.
The toilet seat 112 of the toilet seat apparatus 100 is rotatably supported by the toilet seat apparatus main body 11 via a hollow support shaft 13, and the toilet seat heater 14 is disposed, similarly to the toilet seat 12, but the vibration speaker 20 is not disposed. Further, the toilet seat heater 14 is intermittent in the center portion on the front side of the toilet seat 12 as in the above-described embodiment, and the toilet seat heater 14 is not disposed in the center portion on the front side. The power supply coil 121 is disposed in a hollow portion of the center portion of the front side of the toilet seat 112 where the toilet seat heater 14 is not disposed. The power supply coil 121 is energized through a wire 121a passing through the hollow support shaft 13.
The toilet cover 116 of the toilet device 100 is openably and closably supported by the toilet device main body 11 (toilet seat 112) via a support shaft 116 a. In another embodiment, the toilet lid 116 is configured to have an internal 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 disposed.
In a closed state where the toilet lid 116 covers the toilet seat 112, the power receiving coil 123 is disposed at a position facing the power supply coil 121 of the toilet seat 112. Therefore, in the closed state of the toilet lid 116, electromagnetic induction type wireless power supply can be performed as follows: a current is caused to flow through the power transmission coil 121, and a magnetic flux is changed in the power reception coil 123 to generate an electromotive force, thereby causing the current to flow through the power reception coil 123. Further, wireless power feeding of another mode such as magnetic resonance may be performed as follows: a current is caused to flow through the power supply coil 121, and vibration of the generated magnetic field is transmitted to the power receiving coil 123 to cause resonance, so that the current flows through the power receiving coil 123. Thus, in the toilet seat apparatus 100, the power supply coil 121 and the power receiving coil 123 can be wirelessly supplied, and wireless power supply based on the Qi standard is performed as an example.
The charging unit 124 rectifies the ac power from the power receiving coil 123 into dc power and charges the battery 125. Speaker control device 127 controls vibration speaker 120 so as to operate vibration speaker 120 using the electric power of battery 125. The speaker control device 127 also performs control and communication necessary for wireless power supply based on the Qi standard, and transmits various data necessary for power supply to the control device 19 by wireless communication via the power receiving coil 123 and the power supply coil 121.
In the toilet apparatus 100 configured as described above, an operation related to the generation of pseudo-sound using the vibration speaker 120 is performed as follows. Fig. 9 is a flowchart showing an example of a power supply control routine, and fig. 10 is a flowchart showing an example of a speaker operation control routine. The power supply control routine of fig. 9 is executed by the control device 19. In the power supply control program, 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 with the speaker control device 127 of the toilet lid 116 (S100). Further, an open/close detection sensor for the toilet lid 116 may be provided in the toilet apparatus main body 11, and the control device 19 may detect the closed state of the toilet lid 116 based on a detection signal thereof. When the control device 19 determines that the toilet lid 116 is in the closed state, the wireless power supply is started by starting the energization of the power supply coil 121 (S110).
Next, it waits for determination whether or not charging of the battery 125 is completed (S120) or whether or not the toilet lid 116 is in a closed state (S130). The control device 19 determines the end of charging the battery 125 and the open state of the toilet lid 116 by wireless communication with the speaker control device 127. When the control device 19 determines at S120 that charging of the battery 125 is completed or determines at S130 that the toilet lid 116 is in the open state, the control device ends the wireless power supply by ending the energization of the power supply coil 121 (S140), and ends the power supply control routine.
The speaker operation control program of fig. 10 is executed by the speaker control device 127. In the speaker operation control program, it is determined whether or not the speaker control device 127 is in the state where the toilet lid 116 is opened (S200). In addition, 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 in a state where the charging of the battery 125 is not completed. Alternatively, the speaker control device 127 may detect the open state of the toilet lid 116 based on the connection state of wireless communication with the control device 19, or an open/close detection sensor may be provided in the toilet lid 116 in advance, and the open state of the toilet lid 116 may be detected based on a detection signal thereof.
When the speaker control device 127 determines that the toilet lid 116 is in the open state, an audio signal is output to the vibration speaker 120 and the generation of an artificial sound is started (S210). Therefore, the pseudo sound is generated from the toilet lid 116 (vibration speaker 120) based on the toilet lid 116 being brought from the closed state to the open state. Then, the speaker control device 127 determines whether or not the toilet lid 116 is in the closed state (S220). When the speaker control device 127 determines that the toilet lid 116 is in the closed state, the operation of the vibration speaker 120 is stopped to terminate the generation of the pseudo sound (S230), and the speaker operation control routine is terminated. In this way, the operation of the vibration speaker 120 is started when the toilet lid 116 is in the open state from the closed state, and the operation of the vibration speaker 120 is ended when the toilet lid 116 is in the closed state from the open state. The operation signals from the pseudo sound generation switch 18c and the pseudo sound stop switch 18d may be transmitted from the control device 19 to the speaker control device 127 by wireless communication. Speaker control device 127 may control the start or stop of the operation of vibration speaker 120 based on an operation signal transmitted from control device 19.
The toilet apparatus 100 described above can generate an artificial sound from the vibration speaker 120 by supplying power wirelessly (without contact) through the power supply coil 121 disposed on the toilet seat 112 and the power receiving coil 123 disposed on the toilet cover 116. The toilet seat heater 14 may be disposed on the toilet seat 112, and the wire 121a of the power supply coil 121 may be passed through 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 for passing the wiring 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, it is possible to generate pseudo sound in accordance with the use timing of the user and to suppress unnecessary waste of electric power by the vibration speaker 120. Further, since the power supply coil 121 is disposed in the center portion on the front side of the toilet seat 112 where the toilet seat heater 14 is not disposed, it is possible to wirelessly supply power without hindering the toilet seat heater 14 from heating the toilet seat 112. In the toilet lid 116, a battery 125 and a speaker control device 127 are disposed on a side close to the support shaft 116a (rear side in the closed state), a power receiving coil 123 is disposed on a side away from the support shaft 116a (front side in the closed state), and a vibration speaker 120 is disposed at the center. Since the vibration speaker 120 is disposed at the center, vibration is transmitted to the entire toilet lid 116 without fail, and therefore, the sense of diffusion of sound from behind the user can be improved, and the acoustic effect can be improved. Further, by disposing the battery 125 and the speaker control device 127, which are heavy, on the support shaft 116a side, which is the center of the opening and closing operation of the toilet lid 116, the load applied to the support shaft 116a of the toilet lid 116 can be suppressed, and the opening and closing operation can be performed smoothly.
In another embodiment, the power supply coil 121 is disposed in the center portion on the front side of the toilet seat 112, but the present invention is not limited thereto, and the power supply coil 121 may be disposed in a portion other than the center portion on the front side of the toilet seat 112. In this case, the power receiving coil 123 may be disposed at a position corresponding to the position where the power feeding coil 121 is disposed.
In another embodiment, the power receiving coil 123 is disposed on the front side of the closed state of the toilet lid 116, the vibration speaker 120 is disposed at the center, and the battery 125 and the speaker control device 127 are disposed on the rear side. That is, the locations where the power receiving coil 123, the vibration speaker 120, the battery 125, and the speaker control device 127 are disposed are not limited to the above-described locations, and may be disposed in the toilet lid 116.
In another embodiment, the vibration speaker 120, the power receiving coil 123, the charging unit 124, the battery 125, and the speaker control device 127 are disposed in the toilet lid 116, but the present invention is not limited thereto. Here, fig. 11 and 12 are external perspective views of a toilet seat apparatus 100B according to a modification. As shown in the drawing, in the toilet seat device 100B of the modified example, the toilet seat cover is composed of a front cover 116F that covers the toilet seat 112 in the closed state, and a rear cover 116R that covers the periphery of the support shaft portion of the toilet seat device body 11 and the front cover 116F in the closed state. In this modification, the rear cover 116R has a double-lid structure, and the vibration speaker 120, the power receiving coil 123, the charging unit 124, the battery 125, and the speaker control device 127 are disposed in the rear cover 116R. Although not shown, a power supply coil is disposed in the toilet seat apparatus main body 11. In a state where the rear cover 116R covers the toilet seat apparatus main body 11, the power receiving coil 123 of the rear cover 116R is disposed at a position facing the power supply coil in the toilet seat apparatus main body 11. In this way, as in the case of the toilet apparatus 100, the vibration speaker 120 can be operated by supplying power by wireless power supply. Further, since the power supply coil is disposed in the toilet seat apparatus main body 11, not only the wiring 121a can be shortened as compared with the case where the power supply coil 121 is disposed on the front side of the toilet seat 112, but also it is not necessary to pass the wiring through the support shaft 13. Therefore, the configuration in which the vibration speaker 120 can be operated by wireless power supply is referred to as a simpler configuration.
In another embodiment, the vibration speaker 120, the power receiving coil 123, the charging unit 124, the battery 125, and the speaker control device 127 are disposed in the toilet lid 116, but the present invention is not limited thereto. Here, fig. 13 and 14 are external perspective views of a toilet seat device 100C and a speaker unit 200 according to a modification. As shown in the drawing, the speaker unit 200 of the modification includes the vibration speaker 120, the power receiving coil 123, the charging unit 124, the battery 125, and the speaker control device 127, and these components are housed in the unit case 202. The lateral length (width) of the unit case 202 is formed along the shape of the curved edge portion of the toilet cover 116C and is formed in thickness to be accommodated at the height of the edge portion of the toilet cover 116C. The back surface of the unit case 202 is adapted to be engaged with the engaging portion 128 provided on the lower surface (front surface in the open state) of the toilet lid 116C in the closed state. Therefore, the unit case 202 is detachable from the toilet lid 116C. Further, a power receiving coil 123 is disposed in the unit case 202 such that: when the toilet lid 116C to which the unit case 202 is attached is in the closed state, the power receiving coil 123 is located at a position opposing the power supply coil 121 of the toilet seat 121. In addition, a flat plate or the like may be attached to the cover engagement portion 128 in a state where the unit case 202 is not attached, thereby preventing the external appearance of the toilet lid 116C from being damaged.
In the toilet seat apparatus 100C, the vibration speaker 120 can be operated by wireless power supply, as in the toilet seat apparatus 100. Further, since the speaker unit 200 is configured to be detachable from the toilet lid 116C, if the power supply coil 121 is disposed in the toilet seat 112 in advance, the user can mount the speaker unit 200 on the toilet lid 116C as desired or necessary, and the pseudo sound from the vibration speaker 120 can be generated. When the generation of the pseudo-sound is not necessary, the speaker unit 200 may be detached from the toilet lid 116C.
In another embodiment, the vibration speaker 120 is operated by wireless power supply, but the present invention is not limited to this. For example, a display screen such as a liquid crystal screen may be operated. Further, the speaker unit 200 is illustrated as being attachable to and detachable from the toilet lid 116C, but may be configured as a unit having a display screen.
Here, when the toilet lid is provided with a predetermined function such as a vibration speaker operated by electric power, as in the toilet device of patent document 2 (japanese patent application laid-open No. 2009-125502), it is necessary to pass a wiring for supplying electric power through a support shaft that supports the toilet lid. Therefore, the support structure of the toilet lid must be a dedicated structure. Therefore, in another embodiment, it is a main object to add a predetermined function to the toilet lid without providing a dedicated structure for supporting the toilet lid.
A toilet seat apparatus according to another embodiment includes: a main body fixed to the toilet bowl; a toilet seat supported by the main body; and a toilet lid supported by the main body so as to be openable and closable and covering at least either one of the main body and the toilet seat in a closed state, wherein the toilet device includes: a power supply coil disposed inside the main body or inside the toilet seat; a power receiving coil that is disposed on the toilet lid so as to face the power supply coil in a closed state of the toilet lid, and that receives power from the power supply coil in a non-contact manner; a battery disposed on the toilet lid and capable of charging the power received by the power receiving coil; and a functional unit disposed on the toilet lid and operated by the power of the battery.
In the toilet device of the present invention, the power supply coil is disposed inside the main body or inside the toilet seat, and the power receiving coil that receives power from the power supply coil in a non-contact manner, the battery that can charge the power received by the power receiving coil, and the functional unit that functions with the power of the battery are disposed on the toilet lid. Therefore, since power can be supplied to the functional unit in a non-contact manner by the power supply coil and the power receiving coil, it is not necessary to make the support shaft hollow in order to pass the wiring for supplying power to the functional unit through the support shaft of the toilet lid. Therefore, a predetermined function can be added to the toilet lid without making the toilet lid support structure a dedicated structure. The functional unit may be a vibration speaker that generates sound by vibrating the toilet lid, a display screen such as a liquid crystal screen that can display various information, or a combination of the above configurations. The power can be supplied from the power supply coil to the power receiving coil by an electromagnetic induction type, a magnetic field resonance type, or the like.
In the toilet seat apparatus of the present invention, the toilet seat may be supported by the main body through a hollow support shaft, and the toilet seat may further include a toilet seat heater for heating a seating surface of the toilet seat by supplying electric power through a wire passing through the support shaft, wherein the power supply coil is disposed inside the toilet seat and energized through the wire passing through the support shaft. In this way, the wiring of the power supply coil can be passed through the support shaft of the toilet seat through which the wiring of the toilet seat heater is passed, and a significant increase in the operation load can be suppressed.
In the toilet seat apparatus of the present invention, the central portion of the front side of the toilet seat may have a portion where the toilet seat heater is not disposed, and the power supply coil may be disposed in the portion where the toilet seat heater is not disposed in the interior of the toilet seat. Thus, the non-contact power supply can be performed without preventing the toilet seat heater from heating the seating surface of the toilet seat.
The toilet apparatus of the present invention may further include a control device that controls the functional unit as follows: the operation of the functional unit is started when the toilet lid is in the open state from the closed state, and the operation of the functional unit is ended when the toilet lid is in the closed state from the open state. In this way, the user can appropriately operate the functional unit in accordance with the opening and closing of the toilet lid when the toilet seat device is used, and thus unnecessary waste of electric power can be suppressed.
In the toilet apparatus of the present invention, the battery may be disposed on the rear side of the closed state of the toilet lid, the functional unit may be disposed in the center, and the power receiving coil may be disposed on the front side. By providing the functional portion at the center in this manner, the function of the functional portion can be easily exerted. For example, when a vibration speaker is used as the functional unit, vibration can be transmitted to the entire toilet lid without being biased, and the sound output from the back of the user can be enhanced in a diffuse feeling, thereby enhancing the acoustic effect. Further, since the heavy battery is disposed on the rear side, which is the side where the toilet lid to be opened and closed is supported by the main body, the burden imposed on the support shaft of the toilet lid can be suppressed, and the opening and closing operation of the toilet lid can be smoothly performed.
A functional unit disclosed in a modification of the other embodiment includes: a main body fixed to the toilet bowl; a toilet seat supported by the main body; and a toilet lid openably and closably supported by the main body and covering at least either the main body or the toilet seat in a closed state, wherein the functional unit is attachable to the toilet lid of a toilet apparatus in which a power supply coil is disposed in the main body or the toilet seat, wherein the functional unit further includes: a power receiving coil that contactlessly receives power from the power supply coil; a battery capable of charging the power received at the power receiving coil; a functional unit that functions by the electric power of the battery; and a unit case that is detachably attached to the toilet lid, and that houses the power receiving coil, the battery, and the functional unit so that the power receiving coil and the power feeding coil face each other in a closed state of the toilet lid.
Thus the utility model discloses a functional unit possesses: a power receiving coil that receives power in a non-contact manner from a power supply coil disposed inside the main body or inside the toilet seat; a battery capable of charging the power received at the power receiving coil; a functional unit that functions by the power of the battery; and a unit case configured to be attachable to and detachable from the toilet lid and to accommodate the power receiving coil, the battery, and the functional unit so that the power receiving coil and the power feeding coil face each other when the toilet lid is closed. Therefore, the power supply coil disposed on the toilet seat and the power receiving coil disposed on the toilet cover can supply the operating power to the functional unit in a non-contact manner. Further, since the unit case is configured to be attachable to and detachable from the toilet lid, when the power supply coil is disposed in the toilet seat, the functional unit can be attached to the toilet device to operate the functional unit. Therefore, a predetermined function can be added to the toilet lid without making the toilet lid support structure a dedicated structure. The functional unit may be a vibration speaker that generates sound by vibrating the toilet lid, or a display screen such as a liquid crystal screen that can display various information, or the like.
