物跳ね返りの問題もあった。2. Description of the Related Art As a conventional filth pumping apparatus, for example, Japanese Patent Laid-Open No. 11-342092 is known. This device comprises a manure tank 33 at the bottom of a bowl 31 via an opening / closing mechanism 32.
Since the bowl 31 and the human waste tank 33 are vertically arranged, the user's sitting position becomes high when the human waste tank 33 is placed on the floor, which is not convenient. . Further, regarding the filth transport performance of this apparatus, although heavy filth is gravity-falling, there is no problem, but floating filth has been feared to adhere to the bowl surface.

とが有効とされていた。In order to solve these problems, therefore, there has been proposed a device in which the crushing pressure pump 13 is arranged next to the toilet body 11 as shown in Japanese Patent Laid-Open No. 2001-161597. However, this device has a problem in terms of the performance of transporting heavy filth. That is, in this device, heavy filth has to move laterally until it reaches the crushing pressure-feeding pump 13 after it has fallen to the bottom of the toilet body 11, so it cannot be conveyed by gravity falling alone. In such a case, the same method as in JP 2001-16159 A
As shown in FIG. 7, the washing tank 12 to the toilet body 11
It has been considered effective to supply washing water to and to push heavy dirt into the washing water.

ともあった。However, in this way, when the wash water is sent into the suction pressure feeding chamber including the crushing pressure feeding pump 13 and the like through the waste container of the toilet body 11 and the like,
It has been found that if the suction pressure feeding chamber is closed, the air in the container is compressed by the flow of washing water, and a part of the air flows back to the waste receiving side. According to the conventional technique, as shown in Japanese Patent No. 3104392, the float SW in the storage tank 2 (suction pressure feeding chamber) including the submersible pump 3 is used.
This is because it is common to start driving the submersible pump 3 after the accumulated waste in the waste container reaches 4b. Such backflow of air hinders the transportation of heavy filth. That is, the backflow air becomes a resistance and the flow velocity of the wash water flow decreases.
In addition, heavy air was sometimes pushed back by the backflow air.

After a predetermined time (when the accumulated water level A rises to about 80 mm) after opening 6, the control unit 106 opens the opening / closing valve 402 and simultaneously drives the submersible pump 506. Submersible pump 506
Has a drainage capacity of 30 to 60 L / min. Then, the heavy sewage sunk at the bottom of the sewage receiver 300 is
Due to the head pressure and the water pressure of the wash water D, the movement to the transport path 400 is started together with the surrounding wash water (reserved water) (the accumulated water level A decreases). Here, since the accumulated water level A is lowered and the accumulated water level B is also lowered, the compression of the air in the suction pressure feeding chamber 500 is reduced. That is, before the stored material of the waste container 300 flowing toward the suction pressure feeding chamber 500 after the washing water is supplied reaches the suction pressure feeding chamber 500 (the suction pressure feeding chamber 500).
By decreasing the pressure in the suction pressure feeding chamber 500 (at substantially the same time that the flow starts to flow in the transport path 400 toward), the obstruction of the heavy waste transport by the compressed air is reduced.

The accumulated water level B starts to rise. After that, the accumulated water level B rises for a while, but eventually reaches a peak of about 100 mm and then begins to fall. This is shown in FIG. 9, in which the state of the accumulated water level A is shown in FIG. 9 (a), and the state of the accumulated water level B is shown in FIG. 9 (b). After that, when the accumulated water level A becomes substantially zero and the accumulated water level B becomes less than the height C of the pump suction port 554, the control unit 1

What is different from the previous embodiments is that a trap 408 is provided upstream of the on-off valve 402 of the transport path 400 and that the waste material is pumped. The point is that the apparatus 100 has a caster 108 and is portable. Also in such an embodiment, the same thing as the 1st-8th embodiment can be performed. In the case of the filth pumping apparatus 100 including the trap 408 in the transfer path 400, the degree of hindrance of filth transfer by the compressed air in the suction pressurizing chamber 500 is smaller than that of the filth pumping apparatus 100 having no trap 408. However, as shown in FIG. 17, the transport path 400 extends in the lateral direction of the waste container 300, and the suction pressure feeding chamber 500 is located beside the waste container 300. Therefore, the heavy waste must be moved in the horizontal direction. However, since it is affected by the compressed air in the suction pressure feeding chamber 500 to some extent, it is effective to perform the same operation as in the first to eighth embodiments. In the present invention, "horizontal"
Does not mean right next to. Anything other than "just below" is included in the concept of "sideways." Note that FIG. 17 (a) is the [standby state] of the first embodiment (there is no state in which the accumulated water level A is zero, so there is no [initial state]), and FIG. 17 (b) is the first.
FIG. 17 (c) corresponds to the [pressure supply state] of the first embodiment, [at the start of cleaning] in the first embodiment. In the above-described first to ninth embodiments, the crushing cutter 504 and the submersible pump 506.
Is coaxially connected to the motor 502, and both are connected to the suction pressure feeding chamber 50.
However, the crushing cutter 504 and the submersible pump 506 are driven by separate motors, and the crushing chamber 530 containing the crushing cutter 504 is a suction pressure feeding chamber 500.
It may be provided outside.
