The wastewater flows into the inside from the inflow port in the drainage pressure feed chamber through the passage. The communication part is a drainage channel of a toilet bowl or a drainage connection pipe connected to a drainage port of a toilet bowl, and is attached to and detached from the inlet. Further, the drainage pumping device of the present invention is configured such that the inflow port is opened and closed by an opening and closing unit provided in the inflow port. The opening / closing unit closes the inflow port when not connected to the communication unit, and is opened and drained when wastewater flows in from the toilet in a state connected to the communication unit. Is formed. Here, as the suitable state, the closed state is a state in which the inflow port is kept watertight by the opening and closing unit.
Therefore, the opening / closing part closes the inflow port when the communication unit and the inflow port are not connected to each other, so that there is little possibility that unsanitary residual water or odor in the drainage / pressure feeding device leaks to the outside. In addition, it is difficult for foreign substances to enter and to cause a failure.
[0009]
Examples of the opening / closing unit include a flapper valve having a rotating shaft, a snap valve having a pantograph mechanism, and a movable water conduit that forms a weir and stored water and closes the inlet.

Wherein the opening / closing section closes the inflow port when the communication section is detached.
[0011]
According to this aspect, the pulverizing means is provided with a mechanism for driving the solid waste in the inflowing waste water to be finely divided, and if it comes into contact with a human body, there is a danger of immediately incising the wound. Is high. Some are equipped with grinding means having a sharp structure, which is even more dangerous. The drainage pumping device of the present invention has a structure in which the inflow port is closed by the opening / closing unit when the transmission unit is detached, so that the inside of the drainage pumping chamber is not unexpectedly accessed, and the above-described danger can be reduced. .
Further, similarly to the effect according to the first aspect of the present invention, the opening / closing section closes the inflow port when the communication section and the inflow port are not connected to each other. And odors are less likely to leak out. Further, foreign matters are hardly mixed into the inside of the drainage pressure feeding chamber, so that it is hard to break down.
As a preferred embodiment, the diameter of the inflow port is 50 mm or more, which is particularly effective for a case where a hand or the like is easily inserted. In another preferred embodiment, the drainage pumping device of the present invention is provided at a position where the crushing unit cannot be directly seen from the inlet.

Opening and closing speed can be obtained. Therefore, the drainage pumping device of the present invention, for example, at the time of separation from the communication section, immediately closes the inlet to prevent unsanitary residual water and odor inside the drainage pumping device from leaking from the inlet. .
Further, the drainage pressure feeding device of the present invention, for example, when connected to the transmission portion, when the flapper valve is opened at the time of cleaning, the inflow port can immediately obtain a large-area opening, so that the inflowing wastewater is Immediately, the flow rate becomes large, and a high cleaning and discharging power is obtained. Further, for example, in the drainage pressure feeding device of the present invention, the connection with the communication portion may be made such that the communication portion is inserted into the inflow port, and the flapper valve is large. When the toilet is connected, it operates according to the fitting operation to open the inflow port, and when the communication part is separated, it can also operate to rotate and close according to the separating operation. , Can be interlocked with the attachment / detachment operation of the communication unit.
As a preferred embodiment, the flapper valve may be configured to open and close inside the drainage pumping device. In this case, since the flapper valve abuts and closes from the inside of the drainage pumping chamber toward the outside, the unsanitary residual water inside the drainage pumping device flows backward to the inlet. Also, since pressure is applied in the direction in which the flapper valve closes, there is little possibility that the residual water leaks outside.

In doing so, the opening / closing section 900 does not hinder the flow of drainage. Further, a part of the weir plate 923 forms a headrace of the drainage B, and has an effect of smoothly guiding the drainage B flowing together with the waste C to the unillustrated pumping means in the drainage pumping chamber 500.
[0019]
FIG. 3 shows one use mode in which the drainage pumping device of the present invention and the toilet are connected, and the second embodiment of the present invention in which the drainage pumping device 100 and the communication section 402 of the toilet 300 are connected.

[0023]
FIG. 4 is a configuration diagram as a second embodiment of the present invention in which the drainage pumping device 100 and the toilet 300 are not connected. The drainage pumping device of the present embodiment has the same configuration as the embodiment shown in FIG. The drainage pumping device 100 is detached from the gantry 001 by disconnecting the toilet bowl 300, the drainage pumping tube 750, and the control unit 600. The drainage pumping device 100 in this embodiment is separated from the toilet 300 and is in a portable state.
At the time of carrying, the liquid level of the drainage B remaining in the drainage pumping apparatus 100 may become wet and wet up to the upper part of the inner wall surface in some cases. However, in this case, the opening / closing unit 900 may be urged to close the inflow port 505, and effectively prevent the drainage B from leaking from the inflow port 505 to the outside.
[0024]
Next, an example of the opening / closing unit 900 in the second embodiment of the drainage pressure feeding device of the present invention will be described with reference to the structural diagrams of FIGS. 5 to 8 are elevational sectional views in the vicinity of the opening / closing unit 900 in the present embodiment. FIG. 9 is an exploded perspective view of the opening / closing unit 900. In this example, an opening / closing section 900 is provided at an inlet 505 on the side wall of the drainage pressure feeding chamber 500, and the inlet 505 is configured to open and close.
The specific structure will be described with reference to FIG. 9 (refer partially to FIGS. 5 to 8). The opening / closing unit 900 is configured such that the valve body 913 and the connection arm 924 are connected, and the connection arm 924 is connected to the closing urging unit 930 and the opening urging unit 931 via the driving mechanism 902. This is a flapper valve configured to rotate around a shaft 901. The drive mechanism unit 902 includes an opening / closing unit rotation shaft 901, a transmission variable unit including a drive cam 927 and a driven cam 928, a lever 925, and a bracket 929 including a stopper 9291.
The valve body 913 provided with the sealing material 914 abuts the seat portion 920 to close the inflow port 505. Further, the opening / closing section 900 is turned around the opening / closing section turning shaft 901 by the driving force of a power machine 932 (opening urging means 931) having a driving shaft 926 which is an electric motor, and opens and closes the inflow port 505. (The state shown in FIGS. 7 and 8).
In a state where the power motor 932 is not driven, the valve body 913 is constantly urged by the closing urging means 930 so that the sealing member 914 abuts against the seat portion 920 in a watertight state (the state of FIGS. 5 and 6). .
[0025]
The closing urging means 930 is a coil spring, which is locked by a lever 925 and the other end is locked by a spring fixing portion 912 fixed to the drainage pressure feeding chamber 500, and is held with a predetermined tension. I have.
The opening urging means 931 is a power motor 932, and is electrically driven and controlled by the control unit 600 in FIG. The power motor 932 is fixed to a bracket 929 fixed to the drainage pressure feeding chamber 500, and connects the drive shaft 926 to a convex drive cam 927.
The opening / closing part rotating shaft 901 has a concave driven cam 928 fixed at one end, a connecting arm 924 near the center thereof, and a lever 925 at the other end. Note that the opening / closing unit rotating shaft 901 may have a modified frame structure, and the valve body 913 may be directly connected thereto.
[0026]
The operation structure of the opening / closing section 900 according to this embodiment will be described. FIGS. 5 and 6 show a state where the opening / closing section 900 closes the inflow port 505 (standby state). In the standby state, the closing urging means 930 holds a predetermined tension in the winding axis direction, applies a rotating force of F1 to the opening / closing section rotating shaft 901, and links the valve with the opening / closing section rotating shaft 901. The sealing material 914 is compressed so that the body 913 presses the sheet portion 920 toward the outside of the drainage pressure feeding chamber 500. At this time, the power machine 932 is in a stationary state.
[0027]
The opening / closing section 900 in the second embodiment activates the power unit 932 when the toilet 300 in FIG. 3 is washed, and is brought into a driving state as shown in FIGS. When the power motor 932 is started, a larger acting force F2 opposing the acting force F1 of the closing urging means 930 acts on the opening / closing section rotating shaft 901 to open the opening / closing section 900. Further, after maintaining the fully open state for a predetermined time, the opening / closing section 900 reversely rotates the power machine 932 to close and returns to the standby state.
[0028]
In the above case, the variable coupling means functions as follows. The protruding drive cam 927 has a protruding portion whose rotation section is regulated by the stopper 9291, and rotates in accordance with the forward rotation (at the time of opening movement) and reversal (at the time of closing movement) of the power machine 932. Further, by engaging the concave portion of the concave driven cam 928 with the convex portion of the drive cam 927, the valve body 913 connected to the connecting arm 924 can be rotated in accordance with the forward rotation of the power machine 932. The operation of the drive cam 927 is restricted by the stopper 9291 depending on the positional relationship in the axial direction. However, the driven cam 928 is at a position where it does not interfere in the axial direction, and the rotation of the driven cam 928 is restricted by the stopper 9291. Absent.
Therefore, the valve body 913 performs normal rotation and reverse rotation while the acting force F1 of the opening urging means 930 and the acting force F2 of the power machine 932 acting as the opening urging means 931 act on the on-off valve rotation shaft 901. In the drainage pumping device according to the present embodiment, the opening urging means 931 is electrically controlled to drive the opening / closing unit 900, and always closes the inflow port 505 except when the toilet bowl 300 is being washed.
[0029]
In the second embodiment, the standby state is always maintained. That is, only the acting force F1 of the closing urging means 930 acts on the opening / closing portion rotation shaft 901, and the valve body 913 is brought into contact with the seat portion 920 with a predetermined pressing force.
Therefore, for example, even when the drainage pumping apparatus 100 is detached for maintenance, the inflow port 505 is already closed, and the drainage pumping apparatus 100 is shielded. There is no possibility that the drainage B remaining in the device 100 leaks outside. In addition, foreign matter can be prevented from entering the drainage pumping device 100 from outside.
Even when the valve element 913 receives an external force equal to or greater than the acting force F1 in opposition to the acting force F1, the standby state is automatically restored when the external force is released.
[0030]
10 to 12 are configuration diagrams of the inside of the drainage pumping device 100 in the third embodiment of the drainage pumping device of the present invention, FIG. 10 is a perspective view thereof, FIG. 11 is a plan view thereof, and FIG. FIG. The drainage pumping apparatus 100 according to the present embodiment includes a crushing unit 509 having a cutter 503 disposed coaxially with the motor 512 of the pumping unit 501, and a water conduit 510 that connects the crushing unit 509 and the inlet 505. . Others are the same as the second embodiment of FIG.
The central axis of the inflow port 505 and the rotation axis of the cutter 503 are arranged with a constant inter-axis distance. The headrace 510 has a bent portion 513, and the bent portion 513 forms a shielding wall 514.
In the present embodiment, for example, when the hand is inserted from the inflow port 505 by forcibly opening the opening / closing part 505, the hand collides with the opposite wall surface of the bent part 513, and further reaches in the direction of the cutter 503 (the minimum possible value). When the hand is inserted at the insertion angle θ <b> 1), it is blocked by the shielding wall 514. As described above, the drainage pumping apparatus 100 of this embodiment is configured such that safety measures are taken by the opening / closing section 900, the bent section 513, and the shielding wall 514 to prevent the hand or the like from entering the crushing means 509.
If the work is performed with the inflow port 505 opened for maintenance, or if the hand is forcibly inserted into the closed opening / closing unit 900, if the crushing unit 509 is placed in a position that cannot be directly reached, The risk of immediately suffering such a disaster is reduced.
[0031]
As shown in FIG. 12, the headrace 510 is formed with a downflow gradient θ2.
According to this, even if the drainage pumping device of the present invention is transported at an angle, there is a low risk that the residual drainage flows back through the water conduit 510 to the closed opening / closing section 900. When the door is re-installed, it flows down to the lower part of the drainage pumping chamber 500 without staying there, so that it is possible to prevent the residual drainage from leaking even when the opening / closing section 900 is opened arbitrarily.
