The water supply / drainage cover part 11 is provided behind the toilet body 10, and a water supply valve 90 for supplying water to the bowl part 20, a turn trap part 50, and the like are provided in the water supply / drainage cover part 11.
The toilet device 1 also includes a cleaning switch 12 (see FIG. 1), a water supply unit 3, and a water supply valve 90. The cleaning switch 12 is operated by a user and serves as a trigger for starting cleaning in the bowl portion 20. The washing switch 12 may be provided on the toilet body 10 or may be provided on a remote controller (not shown) provided on a wall surface or the like. The water supply unit 3 is a water supply tank that stores water to be cleaned in the bowl unit 20 and may be provided in the water supply / drainage cover unit 11 or may be externally attached. The water supply valve 90 is controlled to supply water by the control unit 4 (see FIG. 1) constituted by a CPU or the like, and starts and stops water supply into the bowl unit 20. That is, the water supply valve 90 is an electromagnetic valve that opens and closes the valve electrically by a drive command from the control unit 4.
In addition, the water supply part 3 is not limited to the example used as the above-mentioned water supply tank, The structure connected directly to a water pipe may be sufficient.

Furthermore, the toilet device 1 includes a drainage channel 80 that extends from the bowl portion 20 and a turn trap portion 50 that is a bellows-like hollow tube. The turn trap portion 50 is made of rubber, flexible resin, or the like, and has one end connected to the drainage channel 80 and the other end being a free end 50a. And the free end 50a side of the turn trap part 50 can be reversed up and down by the drive of the electric motor M which is the turn trap drive part 9b (refer FIG. 1). The driving source of the motor M is not particularly limited, but may be the same power source as that for driving the cleaning switch 12 (see FIG. 1). In the figure, 51 is a rotating member that rotates the free end 50a of the turn trap portion 50 by driving the motor M. The turn trap driver 9b is driven when receiving a signal from the controller 4, and drives the free end 50a of the turn trap 50 in the vertical direction. The turn trap portion 50 is covered with a case body 52, and an opening 52a is formed on the floor surface side of the case body 52, and floor side drainage connected to a sewer pipe (not shown) is formed in the opening 52a. A tube 53 is connected. The case body 52 is desirably airtight in order to prevent odor leakage from a sewer pipe (not shown).
As shown in FIG. 2 (a), when the free end 50a side is positioned upward as shown in FIG. 2 (a), the turn trap portion 50 is blocked by the drainage of water in the bowl portion 20 and becomes sealed. When the free end 50a side is located in the downward direction as shown in FIG. 4, the water in the bowl portion 20 is drained smoothly.

FIG. 1 is an example of a block diagram of the toilet device 1.
The toilet device 1 receives power supply from a power source 2 connected to a commercial power source during normal operation, and performs washing, draining, sealing, and the like. And a power-off detection unit 6 that transmits power failure detection information to the control unit 4.
The toilet device 1 includes a storage unit 7, a water amount detection unit 8, a turn trap position detection unit 9a, a turn trap, in addition to the water supply valve 90, the washing switch 12, the control unit 4, and the turn trap drive unit 9b. And a drive unit 9b. The memory | storage part 7 is comprised with the memory which memorize | stores the operation state of the toilet device 1 at the time of power-off. The water amount detection unit 8 includes a level sensor or the like, and detects the amount of water in the bowl unit 20. The turn trap position detection unit 9 a detects whether the free end 50 a of the turn trap unit 50 is in the upper or lower position, and transmits the detected position information to the control unit 4.
Here, the method of detecting the amount of water by the water amount detection unit 8 is not particularly limited, and may detect whether or not there is water in the bowl unit 20 or measure the amount of water sealed in the bowl unit 20. It may be. Moreover, the water level of the bowl part 20 may be measured.

Next, an example of the operation of the toilet device 1 during a power failure will be described with reference to FIG.
First, when power off, that is, a power failure is detected by the power off detection unit 6, the backup power source 5 is activated, and the operation state at the time of the power failure is stored in the storage unit 7 (S100, S101). For example, information or the like by the water amount detection unit 8 is stored in the storage unit 7 as to whether or not there is a standby state, that is, whether or not there is water in the bowl unit 20 at the time of a power failure.
After the storage process is completed, the turn trap position detector 9a detects whether or not the free end 50a of the turn trap 50 is in the upper position (S102, S103). When the free end 50a of the turn trap unit 50 is in the upper position, the drive of the turn trap unit 50 is stopped and the drive of the backup power source 5 is also stopped as it is (S104). On the other hand, when the free end 50a of the turn trap part 50 is other than the upper position, that is, when it is off the upper position, the turn trap driving part 9b is driven to move the free end 50a of the turn trap part 50 to the upper position (S105). .
According to the above structure, even if a power failure occurs, the free end 50a of a turn trap part can be moved to an upper position. Therefore, when the water is not sealed at the time of a power failure, if the water pumped into the bucket is supplied to the bowl portion 20, the water sealing to the bowl portion 20 can be achieved.
In addition, operation | movement of the toilet device 1 at the time of a power failure is not limited to the above-mentioned flow, For example, when it detects that the free end 50a of the turn trap part 50 is a lower position, it moves from an upper position to a sealing operation You may make it perform.

Next, an example of the operation of the toilet device 1 at the time of power failure recovery will be described with reference to FIG.
When power supply is recovered from the power supply unit 2 connected to the commercial power source after the power failure, the turn trap position detection unit 9a first detects whether or not the free end 50a of the turn trap unit 50 is in the upper position. . Therefore, if it is a detection result that it is in the upper position, the operation state stored in the storage unit 7 at the time of a power failure is read. If the stored content is a detection result that there is water in the bowl part 20, the normal operation, that is, the standby state is entered as it is (S200, S201). When the detection content of the turn trap position detection unit 9a is other than the upper position, the turn trap unit is moved to the upper position and then water is supplied to the bowl unit 20 (S200, S205 to S207). On the other hand, even if the detection content by the turn trap position detection unit 9a is the upper position, if the storage content by the storage unit 7 is a detection result that there is no water in the bowl unit 20, water is supplied to the bowl unit 20 (S201). , S202 to S204). If the storage content of the storage unit 7 is the amount of water in the bowl unit 20, a predetermined amount of water can be supplied to the bowl unit 20 based on this (S 201, S 202 to S 204).

According to the above, since the state of the toilet device 1 at the time of a power failure is stored and the control at the time of power failure recovery is performed based on the stored state, water supply can be performed only when necessary to the bowl portion 20 at the time of power failure recovery. Therefore, useless water supply can be prevented and the reliability of ensuring the sealing water to the bowl part 20 can be improved.
Specifically, for example, when the bowl portion 20 is not sealed at the time of power failure recovery, the sealed water can be secured even if the user does not perform the toilet bowl cleaning operation (operating the cleaning switch 12). Further, if the storage unit 7 stores a normal standby state at the time of a power failure, that is, a sealed water state, water supply is not performed. Therefore, useless water supply can be prevented and the reliability of securing the sealed water can be improved. .
Furthermore, even if the water level is lowered due to, for example, cleaning at the time of a power failure, or even if the water level is lowered due to some trouble, if the water is supplied based on the detection result of the water amount detection unit 8, the necessary amount of water can be supplied. It is possible to prevent wasteful water supply.

  In addition, the toilet device 1 is not limited to the structure of this embodiment, The operation example of FIG. 3, FIG. 4 is only an example. Moreover, although the toilet device 1 of this embodiment consists of a resin molded product etc. and mainly demonstrated the example which employ | adopted the turn trap system as a drainage structure, it is a trap structure where the drain pipe meandered in the substantially S shape. May be. In this case, the toilet body 10 may be made of earthenware. Although illustration of the toilet lid and toilet seat of the toilet device 1 is omitted, it may be provided, and is not limited to the floor drainage type but may be a wall drainage type. The toilet device 1 may be provided with a cleaning nozzle for cleaning and drying a local part of the human body, a drying function, a toilet seat heating function, and an armrest.
