Fig. 1 shows a toilet apparatus 100 showing an example of an embodiment of the present invention.

In Fig. 1, a state in which the water trap 2 is held is indicated by a solid line, and a state in which the water trap 2 is maintained in a drain state is indicated by an imaginary line.

The toilet apparatus 100 of the present embodiment includes: a tank 1 having a drain port 11 at the bottom thereof; a drain pipe 12 extending horizontally from the drain port 11; and a water trap 2 installed at the downstream end of the drain pipe 12 , freely deformable; and the housing 3, housing the water trap 2.

The water trap 2 is a tubular member having a bellows shape. The upstream end of the water trap 2 is fixed to the downstream end of the drain pipe 12, and the drain pipe 2 is transmitted through the drain pipe 2 so that the drain port 11 of the tank cell 1 and the water trap 2 are connected to each other. The drain port 21 is opened at the downstream end of the water trap 2.

The water trap 2 is disposed in the internal space 31 of the casing 3. The housing 3 has a drain opening 32 at the bottom. The drain port 32 is connected in communication with an external drain pipe (not shown).

That is, the internal space 31 of the casing 3 is a space in which the water trap 2 can be accommodated in a freely changeable state, and this space passes through the drain port 32 and is connected to the external drain pipe so as to communicate with each other.

The state changing means for changing the state of the water trap 2 is constituted by the electric device 4 that mechanically operates the water trap 2. The electric device 4 is composed of a motor (not shown) disposed on the side of the casing 3, and an arm portion 41 that rotates by the rotational power generated by the motor.

The front end portion of the arm portion 41 is mechanically coupled to the downstream end portion of the water trap 2. The state of the water trap 2 is changed in accordance with the rotation of the arm portion 41.

The upstream end of the water trap 2 is fixed to the drain pipe 12 in a state in which the upstream end opening faces the horizontal direction.

The water outlet 2 at the downstream end of the water trap 2 is in a position and a state in which the water trap 2 is opened upward, and is in a position and a state in which the water trap 2 is opened downward when the water trap 2 is in a drain state. The upper part here is not limited to the upper side, but also includes the oblique upper side, and the lower part here is not limited to the right side, but also includes the oblique lower side.

The drain port 21 of the water trap 2 is rotated about the rotation axis of the arm portion 41, and its state is changed between the water sealing state and the drain state.

The water-sealing state of the water trap 2 is shown by a solid line in Fig. 1, and its downstream end portion is located above the upstream end portion, and an arc-shaped curved state is formed from the side. As shown in the imaginary line of Fig. 1, the downstream state of the water trap 2 is lowered to a position lower than the upstream end portion, and an arcuate bending state is formed from the side.

In the present embodiment, the water supply means 5 for supplying water to the water supply pipe 1 and the electric water supply means 5 which is directly connected to the water supply pipe 51 and the electric opening and closing valve 52 inserted in the flow path of the water supply pipe 51 are provided. The water supply means 5 supplies water directly from the water pipe to the tank 1.

Further, the toilet device 100 of the present embodiment includes a partial washing device 6 for discharging the washing water to a part of the user. The partial washing device 6 includes a nozzle 61 that is freely expandable and retractable, and discharges the washing water from the front end portion of the nozzle 61 toward the user.

Further, the toilet device 100 of the present embodiment includes a toilet seat 7 that is freely opened and closed above the tank 1. The toilet 7 has a built-in heater 71. The surface of the toilet seat 7 is heated by energizing the heater 71.

The toilet device 100 of the present embodiment further includes a control unit 8 and a power source 9 (see FIG. 2). The control unit 8 controls the operations of the respective units included in the toilet device 100. The parts, for example, make the water trap 2 The rotating electric device 4, the electric opening and closing valve 52 that controls the feed water to the tank 1, the partial washing device 6, the heater 71 built in the toilet seat 7, and the like.

The control unit 8 further performs charging control of the backup power source 9. The power source 9 is a power source for supplying electric power to the electric device 4 at the time of power failure. The control unit 8 charges the power source 9 every time the power of the toilet device 100 is turned on.

In the present embodiment, power supply to the electric opening and closing valve 52 at the time of power failure is also performed by the power source 9. In other words, the power source 9 also serves as a power source for supplying electric power to the electric opening and closing valve 52 at the time of power failure. Further, in addition to the power source 9 that supplies electric power to the electric device 4 at the time of power failure, a power source that supplies electric power to the electric opening and closing valve 52 at the time of power failure may be provided.

As shown in FIG. 2, the control unit 8 includes a current control unit 81, a device control unit 82 to which a current from the current control unit 81 is supplied, and a charge control unit 83 to which a current from the current control unit 81 is supplied.

The device control unit 82 supplies electric power to the high load device 10 including at least the electric device 4, and drives the high load device 10 to drive the controller. In the present embodiment, the high load device 10 includes a heater 71 for the toilet seat 7 and a partial washing device 6 in addition to the electric device 4.

The control unit 8 further includes a power source voltage detecting unit 84 that detects an input power source voltage, and a charging completion determining unit 85 that determines whether or not the charging operation of the power source 9 by the charging control unit 83 is completed.

In the present embodiment, the charging completion determining unit 85 determines whether or not charging is completed based on the information of the charging time output from the charging control unit 83. Further, it is also possible to determine whether or not the charging is completed based on the charging current information output from the charging control unit 83.

When the power of the toilet device 100 is turned on, the power supply voltage detecting unit 84 having the control unit 8 detects the input power supply voltage, and receives the detection information. The current control unit 81 first supplies the power. The charging control unit 83 is configured to charge the power source 9.

The current control unit 81 does not perform power supply to the device control unit 82 while the charging of the power source 9 is being performed by the charging control unit 83.

Whether or not the charging operation of the charging control unit 83 is completed is determined by the charging completion determining unit 85. When the charging completion determination unit 85 determines that the charging is completed, the current control unit 81 that has received the determination information ends the supply of electric power to the charging control unit 83, and supplies power to the device control unit 82.

In other words, the control unit 8 included in the toilet device 100 of the present embodiment automatically performs the charging operation of the power source 9 immediately after the power of the toilet device 100 is turned on, and in the charging operation, it is assumed that the user operates the control button. The current supply to the high load device 10 is also not performed. The control unit 8 allows current supply to the high load device 10 after the charging operation of the power source 9 is completed.

Here, the high load device 10 includes the electric device 4, the heater 71 for the toilet seat 7, and the partial washing device 6 as described above. Therefore, in the toilet device 100 according to the present embodiment, even if the user operates the control button indicating the drainage in the charging operation of the power source 9, the control unit 8 does not drive the electric device 4 to operate the water trap 2.

Similarly, in the toilet device 100 of the present embodiment, even when the user operates the control button for indicating the heating of the toilet seat 7 in the charging operation of the power source 9, the control unit 8 does not supply the current to the heater 71. Further, even in the charging operation of the power source 9, the user operates the control button indicating the partial cleaning, and the control unit 8 does not supply the current to the partial cleaning device 6.

In Fig. 3, the current supply by the control unit 8 of the present embodiment is schematically shown. The vertical axis represents current and the horizontal axis represents time. As shown, the present embodiment aspect, at times t ₁ after the supply current i (for causing the charging power source 9) _1, 10 allowing the supply current i ₂ for the high load device. Therefore, the supply of the current i ₁ (to charge the power source 9) and the supply of the current i ₂ to the high load device 10 do not occur simultaneously. Therefore, the maximum use current amount can be suppressed, and it is not necessary to design the substrate and the parts to be large because the rated current is increased, and the manufacturing cost can be reduced.

In Fig. 4, the current supply in the comparative example is schematically shown. The vertical axis is current and the horizontal axis is time. In this comparative example, as a conventional technique, a controller who displays the toilet device described above displays a current supply in a case where a high load operation can be performed even during a charging operation.

In this case, the supply of the current i ₁ for charging the power source and the supply of the current i ₂ to the high-load device are required to have the capability of supplying the current i ₁ + i ₂ , so that the manufacturing cost of the toilet device is improved. On the other hand, the toilet device 100 of the present embodiment can be provided at low cost.

As described above with reference to the accompanying drawings, the toilet device 100 of the present embodiment includes the tank 1 having the drain port 11 and the tubular water trap 2 connected to the drain port 11 in an electrically connected manner; The device 4 switches the water sealing state and the drainage state by operating the water trap 2. The toilet device 100 further includes a backup power source 9 that supplies electric power to the electric device 4 at the time of power failure, and a control unit 8. The power source 9 can also be a rechargeable person. In the present embodiment, a large-capacity capacitor is used as the power source 9, but other members such as a secondary battery may be used.

The control unit 8 performs charging control for charging the power source 9 and drive control of the high load device 10 including the electric device 4. The control unit 8 prohibits the drive control of the high load device 10 when charging the power source 9, and allows the drive control of the high load device 10 to be provided when the charging of the power source 9 is completed.

Therefore, in the toilet device 100 of the present embodiment, the supply of the current for charging the power source 9 and the supply of the current to the high load device 10 are not simultaneously performed. Therefore, in the toilet device 100 of the present embodiment, the maximum amount of used current can be suppressed, and it is not necessary to provide a large-sized substrate or each component due to an increase in the rated current, and the manufacturing cost can be reduced.

Further, in the toilet device 100 of the present embodiment, the electric opening and closing valve 52 is further provided to start and stop the supply of water in the tank 1. The power source 9 is also capable of supplying electric power to the electric opening and closing valve 52 during a power failure.

Therefore, in the toilet device 100 of the present embodiment, the water supply to the tank 1 can be started and stopped even in the event of a power failure. Moreover, since the increase in the maximum use current amount is suppressed, the manufacturing cost can be reduced.

Further, in the toilet device 100 of the present embodiment, the control unit 8 is provided to determine whether or not the charging is completed based on the elapsed time or the amount of current charged.

In the case where it is set in such a manner as to determine whether or not charging is completed based on the elapsed time, since complicated detecting means is not required, the manufacturing cost can be further suppressed.

In the case where it is set so as to determine whether or not the charging is completed in accordance with the amount of current to be charged, it is possible to more reliably determine whether or not the charging is completed, and it is possible to charge the power source 9 more reliably.

The present invention has been described above with reference to the embodiments shown in the drawings, but the present invention is not limited to the embodiments, and appropriate design changes can be made within the scope of the invention.
