detailed description

The present invention will be described based on the embodiments shown in the drawings.

In FIG. 1, the toilet device 100 which is an example of embodiment of this invention is shown.

In FIG. 1 , the state in which the water trap 2 is held in the water-sealing posture is shown by a solid line, and the state in which the water trap 2 is held in the drainage posture is shown by a phantom line.

The toilet device 100 of the present embodiment includes: a urinal 1 having a drain port 11 at the bottom; a drain pipe 12 extending horizontally from the drain port 11; and a housing 3 for storing the water trap 2.

The water trap 2 is a cylindrical member having a corrugated shape. By fixing the upstream end of the trap 2 to the downstream end of the drain pipe 12 , the drain outlet 11 of the urinal 1 and the trap 2 are connected through the drain pipe 12 . At the downstream end of the trap 2, a drain port 21 is opened.

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

That is to say, the internal space 31 of the housing 3 is a space where the posture of the trap 2 can be freely accommodated, and this space is connected to an external drain pipe through the drain port 32 .

The posture changing mechanism for changing the posture of the water trap 2 is constituted by an 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 housing 3 and an arm 41 that is rotated by the rotational power generated by the motor.

The front end portion of the arm 41 is mechanically connected to the downstream end portion of the trap 2 . The posture of the trap 2 is changed with the rotation of the arm 41 .

The upstream end of the trap 2 is fixed to the drainpipe 12 with the upstream end opening facing the horizontal direction.

The outlet 21 at the downstream end of the trap 2 is in a position and posture that opens upward when the trap 2 is in a water-sealed posture, and is in a position and posture that opens downward when the trap 2 is in a drainage posture. The above here is not limited to directly above but includes the meaning of obliquely above, and the below here is not limited to directly below but includes the meaning of obliquely below.

The water discharge port 21 of the water trap 2 turns around the rotation axis of the arm 41 to change its posture between the water sealing posture and the drainage posture.

As shown by the solid line in FIG. 1 , the water-sealing posture of the trap 2 is a posture in which the downstream end is lifted above the upstream end and curved in an arc shape when viewed from the side. The drainage posture of the trap 2 is a posture in which the downstream end portion is lowered below the upstream end portion and curved in an arc shape when viewed from the side, as shown by phantom lines in FIG. 1 .

As the water supply mechanism 5 for supplying water into the toilet bowl 1 , in the present embodiment, a water supply pipe 51 directly connected to a water channel and an electric on-off valve 52 present in the flow path of the water supply pipe 51 are provided. The water supply mechanism 5 is a mechanism for directly supplying water from a water channel into the toilet bowl 1 .

Moreover, the toilet device 100 of this embodiment is equipped with the local area washing facility 6 for spraying washing water to a user's area. The local cleaning device 6 includes a nozzle 61 that can move forward and backward, and sprays washing water from the tip of the nozzle 61 toward the user's local area.

Moreover, the toilet device 100 of this embodiment is equipped with the toilet seat 7 which can be opened and closed above the toilet bowl 1. As shown in FIG. The toilet seat 7 has a built-in heater 71 . The surface of the toilet seat 7 is heated by energization to the heater 71 .

The toilet device 100 of the present embodiment further includes a control unit 8 and a power supply 9 (see FIG. 2 ). The control unit 8 controls the operation of each unit included in the toilet device 100 . The above components are, for example, an electric device 4 for rotating the water trap 2, an electric on-off valve 52 for controlling water supply to the toilet bowl 1, a local cleaning device 6, a heater 71 built in the toilet seat 7, and the like.

Furthermore, the control unit 8 controls charging of the backup power supply 9 . The power supply 9 is a power supply for supplying electric power to the electric device 4 during a power failure. The control unit 8 charges the power source 9 every time the power source of the toilet device 100 is turned on.

In the present embodiment, power supply to the electric on-off valve 52 during a power failure is also performed by the power supply 9 . In other words, the power supply 9 doubles as a power supply for supplying electric power to the electric on-off valve 52 during a power failure. In addition, a power supply that supplies power to the electric on-off valve 52 during a power failure may be provided separately from the power supply 9 that supplies power to the electric device 4 during a power failure.

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

The device control unit 82 supplies electric power to the high-load device 10 including at least the electric device 4 , and controls the drive of the high-load device 10 . In the present embodiment, the high-load equipment 10 includes the heater 71 for the toilet seat 7 and the local cleaning equipment 6 in addition to the electric equipment 4 .

Furthermore, the control unit 8 includes a power supply voltage detection unit 84 that detects an input power supply voltage, and a charging completion determination unit 85 that determines whether the charging operation of the power supply 9 by the charging control unit 83 is completed.

In the present embodiment, charging completion judging unit 85 judges that charging is complete based on information on charging time output from charging control unit 83 . In addition, it is also preferable to judge the completion of charging based on the information of the charging current output from the charging control unit 83 .

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

The current control unit 81 does not supply power to the device control unit 82 while the power supply 9 is being charged via the charging control unit 83 .

Completion of the charging operation by the charging control unit 83 is judged by the charging completion judging unit 85 . When charging completion determination unit 85 determines that charging is complete, current control unit 81 , having received the determination information, ends power supply to charging control unit 83 and enables power supply to device control unit 82 .

That is, 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 supply of the toilet device 100 is turned on, and in this charging operation, even if the user operates the operation button, Current supply to the high-load device 10 is also not performed. The control unit 8 permits the current supply to the high-load device 10 after the charging operation of the power supply 9 is completed.

Here, the high-load equipment 10 includes the electric equipment 4, the heater 71 for the toilet seat 7, and the local cleaning equipment 6 as described above. Therefore, in the toilet device 100 of this embodiment, even if the user operates the operation button for instructing drainage during the charging operation of the power supply 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 this embodiment, the control unit 8 does not supply current to the heater 71 even if the user operates the operation button for instructing heating of the toilet seat 7 during the charging operation of the power supply 9 . In addition, during the charging operation of the power supply 9 , even if the user operates the operation button for instructing local cleaning, the control unit 8 does not supply current to the local cleaning device 6 .

FIG. 3 schematically shows the current supply by the control unit 8 of the present embodiment. The vertical axis is current, and the horizontal axis is time. As illustrated, in the present embodiment, after the supply of the current i1 for charging the power supply ₉ is completed at time _t1 , the supply of the current _i2 to the high-load device 10 is permitted. Therefore, the supply of the current i1 for charging the power source ₉ and the supply of the current _i2 to the high-load device 10 are not performed simultaneously. Therefore, the maximum amount of current used can be suppressed, and there is no need to provide a large substrate and components in order to increase the current rating, thereby reducing manufacturing costs.

In FIG. 4 , current supply in the comparative example is schematically shown. The vertical axis is current, and the horizontal axis is time. This comparative example shows the control of the above-mentioned toilet device as the prior art, and shows the current supply in the case where a high-load operation is possible even during the charging operation.

In this case, the supply _of the current i1 for charging the power supply and the supply of the current _i2 to the high-load equipment are performed simultaneously, and a capability of supplying the current i1 _{+ i2} is required, and thus the manufacturing cost of the toilet device increases. On the other hand, the toilet device 100 of this embodiment can be provided at low cost.

As above, as described based on the drawings, the toilet device 100 of the present embodiment includes: the urinal 1 having the drain port 11; the cylindrical trap 2 communicated with the drain port 11; The water trap 2 is operated to switch between the water sealing posture and the drainage posture. Furthermore, the toilet device 100 is provided with the control part 8 and the backup power supply 9 which supplies electric power to the electric equipment 4 at the time of a power failure. The power supply 9 is a rechargeable power supply. In this embodiment, a large-capacity capacitor is used as the power source 9, but other components such as a secondary battery may also be used.

The control unit 8 performs charging control for charging the power supply 9 and drive control for high-load equipment 10 including the electric equipment 4 . The control unit 8 is configured to prohibit the drive control of the high-load device 10 when the power source 9 is being charged, and to permit the drive control of the high-load device 10 when the power source 9 is charged.

Therefore, in the toilet device 100 of this embodiment, the current supply for charging the power supply 9 and the current supply to the high-load facility 10 are not performed simultaneously. Therefore, in the toilet device 100 of the present embodiment, the maximum amount of current used can be suppressed, and it is not necessary to provide a large board and each component in order to increase the current rating, and the manufacturing cost can be reduced.

In addition, the toilet device 100 of the present embodiment is further provided with an electric on-off valve 52 for starting and stopping water supply into the toilet bowl 1 . The power supply 9 also supplies electric power to the electric on-off valve 52 during a power failure.

Therefore, in the toilet device 100 of the present embodiment, the water supply into the toilet bowl 1 can be started and stopped even during a power failure. Furthermore, since an increase in the maximum amount of current used is suppressed, it is possible to reduce manufacturing costs.

Moreover, in the toilet device 100 of this embodiment, the control part 8 is provided so that it may judge completion|finish of charging based on the elapsed time or the amount of electric current charged.

In the case where the completion of charging is judged based on the elapsed time, since a complicated detection mechanism is not required, the manufacturing cost can be further suppressed.

In the case where the completion of charging is judged based on the amount of charged current, the completion of charging can be judged more reliably, so the power supply 9 can be charged more reliably.

As above, the present invention has been described based on the embodiments shown in the drawings, but the present invention is not limited to the above-described embodiments, and appropriate design changes can be made within the intended scope of the present invention.
