It is a time chart of cleaning operation in one embodiment of the present invention. The same as above, shows the case where the lower end of the trap portion is at each position, (a) is a cross-sectional view when it is in the upper position, (b) is a cross-sectional view when it is in the upper upper position, (c ) Is a cross-sectional view in the lower position. It is a block diagram of the structure relevant to a control part same as the above.

  Hereinafter, the present invention will be described based on the embodiment shown in FIGS.

  As shown in FIGS. 2 and 3, the toilet device includes a toilet body, cleaning water supply means 2, a rotatable trap unit 3, and a control unit that controls driving of the cleaning water supply unit 2 and the trap unit 3. 5 is provided.

  As shown in FIG. 2, the toilet body includes a bowl 1, and a case 11 serving as a rear outer shell is attached to the rear part, and a cleaning water supply means 2, a trap part 3, a control part 5, and the like are placed in the case 11. Stored. A discharge port communicating with the trap portion 3 is formed on the rear wall of the lower portion of the bowl 1.

  The cleaning water supply means 2 supplies cleaning water into the bowl 1. Although not shown, the cleaning water supply means 2 is connected to a water supply source such as tap water and communicates with the bowl 1, and a constant flow valve provided in the middle of the water supply path And an on-off valve composed of an electromagnetic valve.

  The trap portion 3 communicates with the inside of the bowl 1 and is provided so that a downstream end 31 thereof is freely rotatable in the vertical direction, and is driven by a driving means 4 such as a motor.

  The control unit 5 is composed of a microcomputer and controls the on-off valve of the cleaning water supply means 2 and the driving means 4.

  Further, a cleaning operation unit 9 (see FIG. 3) that is operated by a user when supplying cleaning water into the bowl 1 is provided.

  In this embodiment, an opening is formed on the floor surface where the case 11 is installed, and the accumulated water 10 and filth discharged from the trap portion 3 are discharged through this opening, but not on the floor surface but on the wall surface. An opening may be formed and discharged in a horizontal manner, and is not particularly limited.

  The basic operation of this toilet device will be described.

  As shown in FIG. 2A, in the state where the downstream end 31 of the trap portion 3 is located at a predetermined position in the upper part of the rotation range (this is referred to as the upper position U), the accumulated water 10 as sealed water 10 Is stored. The stored water 10 is designed so that a predetermined amount is supplied so that the water level becomes a predetermined value.

Further, when discharging the filth accumulated in the water 10, as shown in FIG. 2C, the downstream end 31 of the trap portion 3 is positioned at a predetermined position below the rotation range (this is called a lower position L). ), The accumulated water 10 and the filth in the bowl 1 are discharged.

  When the toilet device is not used, the downstream end 31 is at the upper position U, and when the toilet device is used and the filth and the accumulated water 10 accumulated in the bowl 1 are discharged, the downstream end 31 is at the upper position U. (This embodiment is the upper upper position UU shown in FIG. 2B, which will be described later), and a discharging operation that moves from the lower position L is performed (see time T4 in FIG. 1). The discharging operation is performed by a predetermined operation, and the predetermined operation is not particularly limited as long as it moves at a constant speed, moves in a predetermined pattern, or performs the same operation every time. For this reason, the time required for the discharging operation is a predetermined time T4 as shown in FIG. This predetermined operation is a pattern in which the control unit 5 sends a control signal to the drive means 4 and the like including the following steps. Even if the control signal is sent in the same pattern every time, the load applied to the drive means 4 and the like. Due to this, the actual time may vary. Therefore, the following control is performed.

  In this embodiment, prior to the discharging operation, the downstream end 31 shown in FIG. 2A is at the upper position U, and the downstream end 31 shown in FIG. A preliminary operation is performed in which the vehicle moves to the upper position UU over the predetermined time T2 shown in FIG. 1 and is held for the predetermined time T3. Thereafter, since the discharging operation is performed, the discharging operation in the present embodiment is an operation in which the downstream end 31 moves from the upper upper position UU to the lower position L.

  After the draining operation is finished and the downstream end 31 reaches the lower position L, a holding operation for holding the lower position L is performed for a predetermined time T5.

  After the holding operation, a restoring operation in which the downstream end 31 moves from the lower position L to the upper position U is performed. The restoration operation is a predetermined operation and is performed over a predetermined time T6. The predetermined operation is not particularly limited as long as it moves at a constant speed, moves in a predetermined pattern, or performs the same operation every time. .

  The discharge operation, the holding operation, and the restoring operation are sequence-controlled by the control unit 5 as a series of operations.

  Corresponding to the operation of the trap unit 3, cleaning water is supplied into the bowl 1 by the cleaning water supply means 2. In this embodiment, when the cleaning operation unit 9 is operated, the cleaning operation is started and the supply of cleaning water is started. However, the trap unit 3 holds the trap unit 3 at the upper position U for the first predetermined time T1. Is done. Note that the supply of cleaning water may not be started at the same time that the cleaning operation unit 9 is operated.

  And even if the flow rate of the wash water supplied into the bowl 1 by the wash water supply means 2 fluctuates, the toilet apparatus has a predetermined amount of water as the stored water 10 when the restoration operation is performed. As shown in FIG. 3, a flow rate detecting means 6, a time measuring means 7, and an integrated flow rate calculating means 8 are provided.

  The flow rate detection means 6 detects the flow rate per unit time of the cleaning water supplied into the bowl 1 by the cleaning water supply means 2 and is provided in the middle of the water supply path of the cleaning water supply means 2. As such a flow rate detection means 6, an existing one such as a flow rate sensor in which an impeller is housed in a cylindrical sensor case, and the number of passages of the blades is counted by a hall element provided in the sensor case, and the flow rate is obtained. Can be used and is not particularly limited, and detailed description thereof is omitted.

  In the present embodiment, the time measuring means 7 is provided as one function by the control unit 5, but may be provided separately.

  The integrated flow rate calculation means 8 calculates the integrated flow rate from the flow rate per unit time and time. In the present embodiment, the control unit 5 is provided as one function, but may be provided separately.

  When the stored water 10 is stored, the control unit 5 starts measuring time by the time measuring means 7 from any point in time of the discharging operation. In the present embodiment, as shown in FIG. 1, timing is started at the time when a discharge operation requiring a predetermined time T4 is started.

  Then, based on the time measured by the time measuring means 7 and the flow rate detected by the flow rate detecting means 6 during that time, the integrated flow rate calculating means 8 calculates the supply amount of cleaning water. When the calculated supply amount reaches a predetermined value, the control unit 5 stops the supply of the cleaning water by the cleaning water supply unit 2.

  As a result, the water level of the stored water 10 becomes the upper position U of the downstream end 31 in FIG. If the supply amount exceeds a predetermined value, the upper level U of the water level of the stored water 10 is the limit, so that it overflows from the downstream end 31 and is discharged from the opening. It will increase. In addition, if the supply amount is less than the predetermined value, the water level of the stored water 10 is lower than the upper position U, the amount of the stored water 10 is insufficient, and in some cases, the sealing ability is impaired. There is a concern.

  In the present embodiment, since the flow rate per unit time of the cleaning water is directly detected and the integrated flow rate is calculated based on this flow rate, a predetermined amount of water is supplied even if the flow rate fluctuates.

  Although not shown, the time measurement may be started when the discharge operation requiring the predetermined time T4 is completed, or the time measurement may be started at any point of the discharge operation. Furthermore, although not shown, the timing may be started when the restoration operation requiring a predetermined time T6 is started, or the timing may be started when the restoration operation is completed. Timing may be started at the time.

  That is, the cleaning water that contributes to the formation of the stored water 10 is also the cleaning water supplied slightly before the timing at which the downstream end 31 of the trap portion 3 reaches the upper position U, which is the timing at which the predetermined time T6 is completed. In order to contribute, the timing is started at the time when cleaning water that contributes to the formation of the stored water 10 starts to be supplied, and the cleaning water that is supplied up to that point and does not contribute to the formation of the stored water 10 is accumulated flow rate. It is intended not to be counted on. In this case, the predetermined value of the supply amount is the amount of the stored water 10 at the upper position U in FIG. However, in order to form the predetermined amount of the stored water 10, it does not necessarily have to be performed as described above. For example, even if the start of timekeeping is accelerated, the drained wash water is counted in the integrated flow rate. If the predetermined value of the supply amount is increased, the predetermined amount of the accumulated water 10 can be formed.
