Therefore, the drainage unit of the present invention can be appropriately installed according to the medical condition of the patient.

Another example is a combination of the sitting toilet and the bed. In the case where the user who was originally standing and excreting with the sitting toilet at the side of the bed began to do so in the bed as his condition worsened,
This can be done by arranging one drainage unit and the exterior body separately.

In the drainage device of this embodiment, the drainage unit can be easily attached to the temporary toilet 85, the load load of the user can be supported by the exterior body, and the structure whose position can be easily changed can be realized.

FIG. 14 is a system diagram showing the device configuration of the drainage unit according to the tenth embodiment. Also, FIG.
5 is a control time chart in the tenth embodiment, in which a user operation (input), control (output), (water level) is performed.
It is divided into the states and shown. The user operation (input) shows input signals from the seating switch 102 and the cleaning switch 103, and the control (output) shows output signals to the water supply solenoid valve 61, the on-off valve 21, and the pump 32. ing. Further, as the (water level) state, the water level of the accumulated water 1A in the bowl portion 1 and the water level of the accumulated water 3A in the pressurized discharge portion 3 are shown. Since the pump 32 is driven by the motor, the stirring blade 33 is also driven while the pump 32 is being driven.

Next, these operations will be described. [Initial state] The water supply solenoid valve 61 and the on-off valve 21 are closed, and the pump 32
Is stopped, the water level of the accumulated water 1A in the bowl is 0 mm,
The water level of the accumulated water 3A in the pressure discharge part is about 30 mm (the amount of water is about 1 L).
Equivalent). The water level of the accumulated water 3A in the pressurizing / discharging portion is higher than the height of the pump suction port 35, which means that the pump 32 can be driven without priming.

[Standby state] When the user sits on the toilet seat,
Based on the ON signal from the seating switch 102, the power supply circuit 101 of the control unit opens the water supply solenoid valve 61 and closes the water supply solenoid valve 61 after a predetermined time. While the solenoid valve 61 for water supply is opened, the water level of the accumulated water 1A in the bowl is about 55 mm.
(Equivalent to about 0.7 L of water). FIG. 11 (a)
Shows the state of the accumulated water in the bowl portion 1A, and FIG. 11 (b) shows the state of the accumulated water in the pressurized discharge portion 3A.

[At the start of washing] When the user excretes, the water level of the accumulated water 1A in the bowl portion rises according to the amount of waste. Then, when the user presses the cleaning switch 103, the control unit 64 opens the water supply solenoid valve 61 again based on the signal. After the water supply solenoid valve 61 is opened, the water level of the accumulated water 1A in the bowl portion rises again. FIG. 12A shows the accumulated water 1A in the bowl.
12B, the state of the accumulated water 3A in the pressurized discharge part is shown. The cleaning water supplied from the cleaning spout 62 is preferably 9 to 16 L / min. In this state, the heavy filth is sinking to the bottom of the bowl 1, and the light filth is floating in the bowl 1 due to the flow of washing water.
[At the time of starting pressure feeding] After a predetermined time (when the water level of the accumulated water 1A in the bowl portion rises to about 80 mm) after opening the electromagnetic valve 61 for water supply, the control portion 64 opens the opening / closing valve 21 and simultaneously drives the pump 32. . The drainage capacity of the pump 32 is 30 to 60
L / min. Then, the heavy dirt sunk at the bottom of the bowl portion 1 starts to move to the drainage outlet 14 together with the surrounding washing water (reserved water) due to the head pressure of the water level of the accumulated water 1A in the bowl portion and the water pressure of the washing water. (1A of accumulated water in the bowl
The water level will drop). Here, at the same time that the water level of the accumulated water in the bowl portion 1A is lowered, the water level of the accumulated water 3A in the pressurized discharge portion is also lowered, so that the compression of the air in the pressurized discharge portion 3 is reduced. That is, the weight of compressed air is reduced by lowering the pressure in the pressure discharge part 3 before the accumulated material of the bowl part 1 flowing toward the pressure discharge part 3 after supplying the wash water reaches the pressure discharge part 3. The obstruction of waste transportation is reduced.

In a preferred modification, the control unit 64 opens the open / close valve 21 (the stored material (heavy filth and surrounding storage, cleaning water) in the bowl 1 flows toward the pressurized discharge unit 3. (Before) the pump 32 can be driven. In this case, when the on-off valve 21 is opened, the inside of the pressurizing / discharging portion 3 has a negative pressure, so that the suction force due to this negative pressure can be used for filth transport.

As another modification, the control unit 64 can drive the pump 32 before opening the electromagnetic valve for water supply 61 (before supplying the cleaning water through the cleaning spout 62). In this case, it is necessary to take care so that the water level of the accumulated water 3A in the pressurized discharge portion does not become lower than the height of the pump suction port 35.

[Pressurized state] The water level of the accumulated water 1A in the bowl,
After the water level of the accumulated water 3A in the pressured discharge section is lowered together, when the stored matter in the bowl section 1 reaches the pressured discharge section 3 through the drainage discharge port 14, the water level of the accumulated water 3A in the pressure discharge section rises. Turn to. After that, the water level of the accumulated water 3A in the pressurized discharge portion rises for a while, but eventually reaches a peak of about 100 mm and then begins to fall. FIG. 13A shows the state of the accumulated water 1A in the bowl, FIG.
3 (b) shows the state of 3A of accumulated water in the pressurized discharge part. After that, the water level of the accumulated water 1A in the bowl portion becomes substantially zero, and the water level of the accumulated water 3A in the pressurized discharge portion 3 becomes
When the height is less than 5, the controller 64 stops driving the pump 32. This ends the pressure-feeding state.

The [priming water] control unit 64 keeps the water supply solenoid valve 61 and the on-off valve 21 open even after the pump 32 is stopped, and turns on the water supply solenoid valve 61 and the on-off valve 21 after a predetermined time elapses. Close (Pressurized discharge part 3 even after driving of pump 32 is stopped.
Water is supplied inside. ). This is priming control for making the water level of the accumulated water 3A in the pressurized discharge portion about 30 mm above the height of the pump suction port 35 in the above-mentioned [initial state]. The following are modifications of this priming control. At the same time as the driving of the pump 32 is stopped, the water supply solenoid valve 61,
The on-off valve 21 is closed. At this time, the water level of the accumulated water 3A in the pressurized discharge portion is less than the height of the pump suction port 35. At the next [at the time of starting the pressure feeding], the opening / closing valve 21 is maintained in the half-open state for a predetermined time before the opening / closing valve 21 is fully opened and the pump 32 is started to be driven simultaneously. As a result, before the driving of the pump 32 is started, the water level of the accumulated water 3A in the pressurized discharge portion is set to about 30 mm which is higher than the height of the pump suction port 35.

Here, the full opening of the on-off valve 21 means the state shown in FIG.
The state of (b) is shown, and half-opening of the on-off valve 21 means
It is assumed that an intermediate state between FIG. 6A and FIG. 6B is shown. For example, with the reference position in FIG. 6B, the on-off valve 21 can be rotated by 10 ° about the rotary shaft 23 in a half-open state, and rotated by 90 ° in a fully-open state. FIG. 16 is a diagram showing an eleventh embodiment of the present invention. The feature of this embodiment is that a drain trap 13 is provided upstream of the on-off valve 21 of the accumulated water holding portion 2 and at the bottom of the drain unit. It is provided with a water supply pipe connector 52 and a drainage pipe connector 51, and the drainage unit is a portable type with a cartridge cart having casters 93 attached. The drainage pipe connector 51 and the water supply pipe connector 52 may be rotatably connected to each other, which has an advantage that there is no restriction on the direction when the drainage unit is moved.

Further, the upper part of the cartridge cart has a chuck structure for mounting and fixing the drainage unit. For example, the structure is such that the drainage unit is slid from the side or pressed by being chucked from above. May be
In a further preferred embodiment, the chuck structure is provided with a connector for the secondary water supply system pipeline and the primary drainage system pipeline, and at the time of mounting the drainage unit on the cartridge cart, pipe connection construction is performed at the same time. It is a structure that can do. Therefore, the pipe connecting work does not need to be separately performed after the locking work, and the construction can be easily completed. Further, as a preferred embodiment, the connector of the pipeline is a primary water supply pipeline that communicates with a water main and is connected to a secondary water pipeline, and a secondary drainage pipeline that communicates with a sewer main. It can also be equipped with a connector for the road and is a structure that can be freely rotated. Therefore, when it is desired to change the installation direction of the drainage unit on the cartridge cart, it is not necessary to loosen the connector of the connected and fixed pipeline as in the conventional case. Further, if the conduit connected to the connector is flexible, the mobility of the drainage unit can be further improved.

In the case of the drainage unit having the drainage trap 13 in the accumulated water holding portion 2, the degree of hindrance of the waste transportation by the compressed air in the pressurized discharge portion 3 is smaller than that of the drainage unit having no drainage trap 13. Become.

However, as shown in FIG. 16, since the accumulated water holding portion 2 extends in the lateral direction of the bowl portion 1 and the pressure discharge portion 3 is positioned beside the bowl portion 1, the heavy filth is laterally moved. Since it is inevitable to move to and is affected by the compressed air in the pressurized discharge portion 3 to some extent, it is effective to perform the same drive control as in the tenth embodiment. When the same drive control is performed, the state shown in FIG. 16 shows the “standby state”, the state shown in FIG. 17 shows the “starting cleaning”, and the state shown in FIG. 18 shows the “pressure feeding state”. In the present invention, "lateral" does not mean just beside. Except "underneath", it is included in the concept of "horizontal".
