There was a problem that unpleasant noise was generated. Furthermore, since the drainage system is designed to suck up waste water from the bottom of the bottomed casing 3, there is also a problem in that contaminants with light specific gravity floating on the surface of the drainage water are difficult to be sucked into the impeller chamber 14 through the suction port 6. In addition, there is the problem that cleaning the casing of the submersible pump 5 when it becomes dirty with limescale or foreign matter from wastewater is unpleasant and troublesome, and fine dust such as hair that is not collected by the mesh basket 4 gets wrapped around the impeller 15. Submersible pump 5
There is also the problem that the submersible pump 5 may malfunction due to an increase in the motor load. A failure of the submersible pump 5 may also occur when the waterproofness of the shaft sealing portion of a rotating part such as the impeller 15 is impaired. Also,
Since the submersible pump 5 is heavy, there is an inconvenience that a large load is always applied to the attachment point of the bottomed casing 3 to the drain port 2.

強制排水が止まる。[0008] When water flows into the bottomed casing and its internal water level rises, from when the second detection means detects the lower limit of the water level to when the first detection means detects the upper limit of the water level, the water level increases. It flows into the wastewater intake chamber under its own weight. Therefore, when the water level is higher than the drainage outlet passage of the drainage intake chamber, water is naturally drained. When the water level rises further and the upper limit of the water level is detected by the first detection means, the on-off valve is opened by the action of the control section, and water is forced into the pressure storage chamber through the water passage using the water pressure that is constantly applied in the water pipe, and the turbine After rotating the impeller, the tap water is drained through the outlet passage. When the turbine impeller is rotated by the water pressure of the tap water in this way, the drainage impeller installed in the wastewater intake chamber rotates, which forces the water in the wastewater intake chamber. is discharged. When the water level becomes low due to such forced drainage and the second detection means detects the lower limit of the water level, the control unit closes the on-off valve.
Forced drainage stops.

。When the water from the faucet 41 or the water in the water reservoir 1 flows into the bottomed casing 3 from the drain port 2 and the internal water level rises, the water level rises until the water level reaches the drain pipe connection port 46. The water collects in the drainage intake chamber 33, the drainage outlet passage 44, and the bottom of the bottomed casing 3. Then, from the time when the water level reaches the drain pipe connection port 46 until the upper limit water level H is detected by the first detection means 21, the on-off valve 42 remains closed, and the water flows into the bottomed casing 3. The water flows through the water intake 35, the wastewater intake chamber 33, and the wastewater outlet passage 44 due to the drop of the water, accompanied by an internal vortex flow, to the drain pipe connection port 4.

が閉じ、強制排水が止まる。[0018] As the water level becomes higher, the first detection means 21
When the water level upper limit H is detected, the detection signal is sent to the control unit 23.
The on-off valve 42 is opened in response to a command from the control unit 23. Therefore, water is forced into the impeller chamber 36 through the water passage 39 by the water pressure constantly applied in the water pipe 40, rotates the turbine impeller 55, and then passes through the opening 52 and the tap water outlet passage 49 to the outlet 50. The water is vigorously sprayed from the drain pipe connection port 46. When the turbine impeller 55 is rotationally driven by the water pressure of tap water in this way, the rotation is caused by the connection shaft 59.
The water is transmitted to the drainage impeller 56, and the drainage impeller 56 rotates as a result of the turbine impeller 55. Due to the driven rotation of the drainage impeller 56, the water that has flowed into the drainage intake chamber 33 through the water intake 35 while accompanied by a vortex is forcibly discharged to the drainage pipe connection port 46 through the drainage outlet passage 44. Ru. At this time, since tap water is vigorously jetting out from the outlet 50 of the tap water outlet passage 49, the suction action of the jetting water flow further promotes forced drainage from the drain pipe connection port 46, resulting in prompt drainage. be exposed. When the water level becomes low due to such forced drainage and the lower limit L of the water level is detected by the second detection means 22, the on-off valve 22 is activated by a signal from the control unit 23.
closes and forced drainage stops.

用羽根車５６の作用で排出される。When such forced drainage is being performed, even when the water level is close to the water intake port 35, the water flowing into the drainage intake chamber 33 is prevented by the drainage impeller 56.
This is done not only by the water suction action that accompanies the rotation of the
This is also done by the weight of the water itself, so
Until the water in the bottomed casing 3 completely flows into the drainage intake chamber 33, it becomes difficult for air to be drawn into the drainage intake chamber 33, making it difficult for discharge failure to occur, and at the same time, the discomfort caused by air entrainment is reduced. Sound is also less likely to be generated. In addition, since the water in the bottomed casing 3 flows into the wastewater intake chamber 33 from the water intake port 35 while being accompanied by a whirlpool, contaminants with a light specific gravity also effectively flow into the wastewater intake chamber 33 together with the water, and the It is discharged by the action of the impeller 56.

室３３に流し込むことに役立つという利点がある。By the way, as shown in FIGS. 1 and 2, in this embodiment, the tap water outlet passage 49 is provided with a branch passage 61, and the branch passage 61 is connected to the bottom wall 2 of the bottomed casing 3.
4, and a cover body 62 is provided to cover the opening, and the guide action of the cover body 62 causes tap water to flow in the flow direction of the vortex F generated in the bottomed casing 3 during forced drainage from the branch passage 61. It is designed to be discharged in the direction along the line. By doing this, the force of the vortex F generated inside the bottomed casing 3 during forced drainage is transferred to the branch passage 6.
The flow is further strengthened by the discharge flow from the bottom casing 3, which helps water flow into the drainage intake chamber 33, and also removes foreign substances that try to stay on the bottom wall 24 of the bottomed casing 3 and the inner surface of the attachment 26. This has the advantage of being useful in forcing the water to flow from the water intake port 35 into the wastewater intake chamber 33.

る。Further, in this forced drainage device, the drainage impeller 56 only rotates as the turbine impeller 55 is rotationally driven by the water pressure of the tap water; Since it is not driven by the water source, fine impurities such as hair that are not collected by the mesh basket 4 during forced drainage may be sucked together with water from the water intake port 35 and become wrapped around or tangled with the drainage impeller 56. However, there is no need to worry about malfunctions caused by this, and normal operation can be restored simply by removing the contaminants.

こともなくなる。[Effects of the Invention] According to the present invention, during forced drainage, air is less likely to be drawn into the drainage intake chamber in which the drainage impeller is installed, so it is less likely that water will be discharged improperly to the discharge side. , unpleasant noises caused by air entrainment are less likely to occur. In addition, drainage is performed by the rotation of the drainage impeller following the rotation of the turbine impeller driven by the water pressure of tap water, which simplifies the water sealing structure of the shaft seal and reduces power consumption compared to conventional methods. In addition, since a heavy rotational drive source such as a motor is not required, the forced drainage mechanism is lighter than before, and there is no need to place a large load on the mounting point of the bottomed casing to the drain outlet of the sink etc. It is no longer possible for a situation in which the There will be no more problems caused by hair etc.
