Description

  The present invention relates to a toilet device having a trap portion that is rotatable upward (water storage position side) and below (drainage position side).

  In this type of toilet device, a 100 V AC power supply is generally used as a drive power supply for the trap section. Therefore, an apparatus using a rechargeable battery as a backup power source has been proposed in order to avoid a situation in which the trap unit does not operate due to a power failure or the like (see, for example, Patent Document 1).

  The thing of patent document 1 becomes a structure which charges a rechargeable battery with the electric power generated with the hydroelectric generator built in the apparatus for every water flow generation. Therefore, the trap part can be normally operated by a fully charged rechargeable battery at the time of a power failure.

Hereinafter, the overall configuration and characteristics of the toilet device 1 will be described in detail.
The toilet device 1 is a Western-style toilet device. As shown in the longitudinal sectional views of FIGS. 3 (a) and 3 (b), the toilet device 1 is provided with a bowl portion 10 that opens upward, and a storage space portion 12 is provided in the rear space thereof. is there. A case main body 13 is housed in the storage space 12.

  An attachment hole 13a is provided in the side wall of the case body 13 on the bowl part 10 side, and a trap part 20 in which the free end 21 of the rear end part can be turned upside down is attached to the attachment hole 13a. Most of the trap part 20 is disposed in the case body 13, while the connection part 22 at the front end of the trap part 20 protrudes from the case body 13. The connecting portion 22 is fitted and connected to the drain port 11 formed at the rear end portion of the bowl portion 10.

  The trap part 20 is formed in the bellows cylinder shape with the soft material. As shown in FIGS. 3 (a) and 3 (b), in the case main body 13, the trap portion 20 is operated by the rotating body 23 by the driving means (turn trap motor 32) (see FIG. 2), and the free end 21 is moved. The rear end portion is turned so as to be reversible in the vertical direction.

  The rotating body 23 is disposed behind the trap unit 20 so that the free end 21 of the trap unit 20 rotates when driven by a turn trap motor 32 (hereinafter referred to as a motor 32) disposed outside the case body 13. Connected to the end. That is, when the motor 32 is rotated in one direction, the trap 32 is turned downward so that the free end 21 of the trap portion 20 faces downward. On the other hand, when the motor 32 is rotated in the opposite direction, the free end 21 of the trap portion 20 is turned upward. Rotate to position.

  When the trap unit 20 moves up and down, each position (upper position: water storage position side, lower position: drainage position side) is detected by a turn trap position sensor 36 (see FIG. 2; hereinafter referred to as position sensor 36). And controlled to stop at those positions. The upper position is a position where water is stored in a sealed state in the bowl portion 10, while the lower position is a position where water in the bowl portion 10 is discharged.

  A discharge hole 13b is provided in the lower part of the case body 13, and an external drain pipe (not shown) is connected to the discharge hole 13b. That is, the drainage channel 2 is constituted by the drainage port 11 of the bowl portion 10, the trap portion 20, and the external drainage pipe.

  A water supply passage 34 for supplying water to the bowl portion 10 is disposed on the upper portion of the case body 13. The water supply channel 34 communicates with a rim portion 35 for water passage formed at the upper end opening edge of the bowl portion 10 at the tip end and is connected to the water pipe at the other end. A water supply means 33 including a water supply electromagnetic valve for opening and closing the water supply passage 34 is provided in the middle of the water supply passage 34.

  Although not shown, the toilet device 1 is provided with a toilet seat and a toilet lid rotatably attached thereto. These may be automatically rotated by a toilet seat / toilet lid opening / closing drive means (not shown).

  In the normal drainage, the trap portion 20 moves up and down by the operation of the washing switch 37 at the free end 21. Hereinafter, a cleaning operation involving water supply to the bowl unit 10 by the water supply means 33 will be described.

In the initial state, the free end 21 of the trap part 20 faces upward as shown in FIG. That is, the free end 21 of the trap part 20 exists in an upper position (water storage position side). Thus, when the free end 21 of the trap part 20 exists in an upper position, the water in the bowl part 10 and the trap part 20 has accumulated and it is in the sealed state.
When the toilet is operated in this state and the cleaning switch 37 is operated after the toilet is completed, the following operation is executed in accordance with an instruction from the control unit 30.

First, the water supply means 33 is turned on and water supply to the bowl portion 10 is started, the motor 32 is driven, the free end 21 of the trap portion 20 rotates downward, and stops at the lower position (drainage position side). The sewage is discharged (see FIG. 3B).
The free end 21 of the trap part 20 is hold | maintained for a fixed time at the drainage position side. During this time, sewage flows to the external drain.
After a predetermined time has elapsed, the motor 32 is driven, the free end 21 of the trap portion 20 is rotated upward, and stops at the water storage position side.
After the trap unit 20 stops on the water storage position side, the water supply means 33 is turned off after a lapse of a certain time, and a certain amount of water is stored in the bowl unit 10 to be in a sealed state (see FIG. 3A). .

Such a cleaning operation is performed by driving the control unit 30, the motor 32, the water supply means 33, and the like that are energized from the power supply unit 38 (see FIG. 2) when the cleaning switch 37 is operated. .
The control unit 30 is configured by a CPU or the like, has a timer, and has an operation configuration that outputs commands so that each unit operates at various timings such as operation of the cleaning switch 37.

  The toilet device 1 according to the present embodiment is provided with a backup power supply in case the energization from the power supply unit 38 is interrupted by a power failure or the like. The backup power source includes a battery 31 that is detachably mounted.

This backup power supply is connected so as to energize the pseudo load 45, the water supply means 33, the motor 32, the turn trap position sensor 36, the notification unit 39 and the control unit 30 configured by a buzzer and a lamp. A power failure switch 40 is connected to the backup power source, and the switch detection unit 42 detects the switch operation and notifies the control unit 30 that the power failure switch 40 has been operated.
The backup power source includes a low voltage detection unit 41 (low voltage detection IC) that detects that the battery voltage has fallen below a predetermined voltage threshold V3 (see FIG. 4B) when the power failure switch 40 is operated. ) Is connected.

  Further, the pseudo load 45 is configured by a resistor or the like as described above, and is connected to the battery 31 via the energization switch 46. The energization switch 46 is a relay switch that is turned on / off by a command from the control unit 30 that receives energization from the battery 31.

  The power failure switch 40 is an operation switch for causing the trap unit 20 to perform a predetermined series of operations. In the present embodiment, it is detected that the power failure switch 40 has been operated, and the pseudo load 45 is energized. By the energization, the battery 31 is judged to be deteriorated, and an operation corresponding to the deterioration (consumption) of the battery 31 is performed. It has become so.

The series of operations is a reset operation at the time of a power failure, and is an operation for the user to determine whether or not the trap unit 20 operates normally. The series of operations is an operation in which the free end 21 of the trap portion 20 first moves to the drainage position side, maintains a state for a certain time on the drainage position side, and then moves to the water storage position side that is the original position. (Refer to Drawing 5 (a)-(c)).
By the movement of the trap unit 20 toward the drainage position, which is the first operation in this series of operations, the sewage accumulated in the bowl unit 10 is discharged.

  The basic operation when the power failure switch 40 is operated will be described below with reference to the flowchart of FIG. 1, the block diagram of FIG. 2, and the graphs of FIGS. 4 (a) and 4 (b).

The graph of FIG. 4A is an example pattern in which the battery 31 is determined to have a voltage drop. The voltage within the time T1 from when the trap unit 20 starts moving from the water storage position side to when it moves to the drainage position side. An example in which a decrease occurs is shown. V1 in the graph is a voltage value when the battery 31 is deteriorated. V2 is a lower limit value of the operating voltage of the motor 32.
In order to detect a voltage drop as shown in FIG. 4A by energizing the pseudo load 45, as shown in FIG. 4B, corresponding to the graph of FIG. 4A. A voltage threshold V3 for low voltage detection by the pseudo load 45 is set in the low voltage detection unit 41. T2 is a monitoring time for energizing the pseudo load 45 to detect low voltage detection.

When a power failure occurs, a power failure standby mode is set (101 in FIG. 1). In this mode, even if the battery 31 is mounted as a backup power source, power is not supplied to each part, and the cleaning operation is not performed even if the cleaning switch 37 is operated.
In the toilet device 1, a power failure can be detected using a zero cross circuit (not shown).

When the power failure switch 40 is operated in this power failure standby mode, if the battery 31 is installed as a backup power source, the operation is triggered by the operation, and the power failure mode (available state) is entered. Notification is made (101 to 103 in FIG. 1).
Further, the control unit 30 turns on the energization switch 46 to energize the pseudo load 45 (104 in FIG. 1).

The deterioration of the battery 31 is determined based on whether or not the low voltage detection unit 41 detects low voltage within a predetermined time T2 (see FIG. 4B) (105 in FIG. 1).
When the battery voltage falls below the voltage threshold V3 and it is determined that there is a deterioration (see FIG. 4B), the notification unit 39 notifies that the battery is dead (105 and 108 in FIG. 1). And it waits for the re-operation of the power failure switch 40.

If it is determined that there is no deterioration (normal), the trap unit 20 is controlled to perform the above-described series of operations (106 in FIG. 1).
Thus, if it is determined that there is no deterioration, the trap unit 20 moves to the water storage position side and stops after holding for a certain time on the drainage position side (107 in FIG. 1). Further, when the operation is completed, the power failure switch 40 can be operated again (107 in FIG. 1).

Thus, even when the battery 31 is degraded when the power failure switch 40 is operated during a power failure, the degradation can be easily determined by energizing the pseudo load 45. Since there is a notification of deterioration, the user can immediately replace the battery with a new one.
In addition, when it is determined that there is deterioration, a series of operations of the trap unit 20 scheduled to be operated by the operation of the power failure switch 40 become invalid and no moving operation is performed. It can be avoided that the trap unit 20 becomes inoperative.

When it is determined that there is no deterioration, the trap unit 20 subsequently performs a series of operations, and thus can discharge sewage to the outside.
The series of operations may be performed with water supply. In that case, the bowl part 10 can be in a sealed state only by operating the power failure switch 40. Thereafter, the cleaning operation of the bowl unit 10 by the normal cleaning switch 37 can be executed.

Further, instead of the power failure switch 40, the deterioration determination operation by the pseudo load 45 may be executed by another switch operation. In the case where the battery 31 is always mounted, the deterioration determination operation may be executed at a regular timing (for example, once a week).
Of course, when the deterioration determination is performed at these timings, it is not based on the operation timing of the power failure switch 40 and is not intended to cause a series of operations. Therefore, it is desirable not to cause the trap unit 20 to perform a series of operations.
