The electromagnetic valve on the water inlet pipeline can also be controlled by a liquid level controller in the water collector.

For example, the secondary water turbidity identification flow dividing device may be such that: establish the induction zone of a quality of water turbidity degree on this inlet tube of water collector, at this department pipe wall mounting photoelectric sensor the low reaches of induction zone is equipped with two branch road pipes: one of the branch pipes is a water collecting pipe and is communicated with the secondary water inlet on the wall of the water collecting space, the other branch pipe is a sewer pipe and is communicated with the overflow space, an electromagnetic valve is arranged on the water collecting pipe and is controlled by the photoelectric sensor through a control circuit, when the turbidity of the secondary water passing through the induction area is greater than the set value of the photoelectric sensor, the electromagnetic valve on the water collecting pipe is closed, the secondary water is directly discharged to the overflow space from the sewer pipe and cannot enter a toilet flushing water tank, when the turbidity of the secondary water passing through the induction area is less than the set value of the photoelectric sensor, the electromagnetic valve on the water collecting pipe is opened, and the secondary water enters the water collecting pipe and enters the water collecting space;

The secondary water inlet pipe can be provided with a water return bend, and the photoelectric sensor is arranged at the water return bend.

The device for identifying the secondary water turbidity is suitable for collecting secondary water by gravity, such as a water collector arranged below a wash basin or a vegetable washing basin.

The specific action principle is as follows:

when the water in the water collector is satisfied, the photoelectric sensor does not work, the electromagnetic valve on the water collecting pipe is closed, and the drainage of the washing basin or the wash basin is directly drained to the overflow space of the water collector through the diversion pipeline and then is drained to an outdoor drainage pipeline.

When the water collector needs to be replenished with water, the liquid level controller in the water collector sends a water replenishing instruction. At the moment, the photoelectric sensor starts to work, the electromagnetic valve on the water collecting pipe is opened to identify the sewage, and when the sewage in the washing basin or the hand washing basin meets the use standard, the sewage is supplemented to the water collector through the water collecting pipe. If the water in the washing basin or the hand washing basin does not meet the use standard, the sensor on the water collecting pipe responds to close the electromagnetic valve, so that the water which does not meet the use standard enters the overflow space through the diversion pipeline and then is directly discharged outdoors, and the electromagnetic valve is opened after the water is identified by the photoelectric sensor until the water meets the use standard, and then the water is supplied to the water collector. After water is supplemented, a water full signal is sent by a liquid level controller in the water collector, at the moment, the photoelectric sensor stops working, and the electromagnetic valve is closed. And finishing the water replenishing program. At this time, if secondary water is discharged, the secondary water is directly discharged through the sewer pipe.

The washing machine is generally placed in a corner of a living room, and if a water collector for collecting secondary water by gravity is placed under or at a side of the washing machine, the washing machine occupies a space, and in addition, the appearance of the living room is damaged and the use of the washing machine is influenced. As is the case with bathtubs. However, there is typically a small space under the tub. In a household having both a washing machine and a bathtub, one of said catchments may be used to collect secondary water discharged by both devices: the wall of the water collecting space of the water collector is provided with a water inlet, and the water inlet and the liquid level controller arranged in the water collecting space are arranged in a staggered manner. The reason is that the water storage capacity of the washing machine or the bathtub is large, the impact force of water during water discharging is large, and the accuracy of the liquid level controller is prevented from being influenced by the fact that a water head with large impact force directly impacts the liquid level controller due to the staggered arrangement of the water storage capacity and the water storage capacity of the washing machine or the bathtub. And a secondary water outlet of the water collector is arranged on the side wall of the water collecting space, and the outlet is connected with a water inlet of the conveying pipeline leading to the water tank or water inlets of the water collecting spaces of other water collectors. A water draining opening of the water collecting space is arranged at the bottom of the partition wall between the water collecting space and the overflow space of the water collector, and an overflow weir is arranged at the top of the partition wall. After the washing machine or the bathtub finishes draining, the residual secondary water in the water collecting space can flow into the overflow space from the water draining opening in a short time and then is drained into a sewer, and no residual water is left in the water collector. The wall of the overflow space of the water collector is preferably provided with a secondary water inlet, and a connecting pipe is arranged on the secondary water inlet and is connected with the overflow port of the bathtub, so that overflow liquid flowing out of the overflow port of the bathtub directly enters the overflow space. The design is that the overflow port of the bathtub overflows water on the water surface of the bathtub, and the water is often provided with a plurality of floating objects, and the water is introduced into the water collecting space, wherein the floating objects can block the device, particularly the water collecting space, a water pump of a conveying pipeline and the like.

For the water collector, the structure of the secondary water turbidity identification flow dividing device can be as follows: the secondary water turbidity identification and diversion device is connected with the secondary water inlet pipe of the water collector, one or more branch pipes are connected with the water inlet pipe in front of the identification device and are respectively connected with a drain pipe of a washing machine, a drain pipe of a bathtub and the like; the secondary water turbidity identification and diversion device is controlled by a liquid level controller in the water collector, and is also controlled by the liquid level controller in the water tank or the water collector receiving secondary water of the water collector, and the identification device also controls the action of a water pump on the water conveying pipeline; the power supply in the secondary water turbidity identification and diversion device is connected with a low-voltage power supply through a normally closed and/or normally open contact of a liquid level controller in the water collector; the normally open and/or normally closed contacts of the built-in relay of the secondary water turbidity identification shunt device are connected in series in a contactor coil power supply loop for controlling the action of a water pump driving motor.

When a water tank or other water collectors arranged in front of the water collector need to be supplemented with water, the bathtub sewer and the washing machine sewer enter the water collecting area of the water collector and are identified by the identification device.

The working principle is as follows: when the water tank or the water collector which is arranged in front of the water tank and uses the water in the water collector as water supplement needs water supplement, the liquid level controller in the water tank or the water collector in front sends a water supplement signal, at the moment, water exists in the water collector, the photoelectric sensor starts working to identify the lower water, and when the water quality does not meet the use standard, the water is directly discharged into the overflow area and directly discharged to the outside. When the water quality meets the standard, the sensor identifies and gives an instruction, the water pump arranged on the conveying pipeline is started, when the toilet flushing water tank or the front water collector is full of water, the water pump stops working, the sensor stops working at the same time, and the water supplementing program is completed.

The photoelectric sensor and the electromagnetic valve are all safe in voltage, personal safety is guaranteed, and all control circuits are combined with an original reclaimed water system control circuit to complete program control of the whole reclaimed water system.

The water conveying pipeline is provided with a check valve, so that secondary water can only flow towards the direction of the toilet flushing tank, and otherwise, the secondary water is stopped; the water pump can be effectively prevented from being incapable of delivering water and damaging the water pump due to no water in the water suction pipe of the water pump on the pipeline.

In the device, the electromagnetic valve can be opened and closed according to a liquid level signal of the liquid level controller and the driving motor of the water pump is started and stopped, the water pump and/or the electromagnetic valve on the water collecting pipeline can be opened and closed according to a signal sent by the photoelectric sensor, and finally secondary water with the cleanliness meeting the requirement enters the water tank, and the secondary water which does not meet the requirement is directly discharged into a sewer.

Detailed Description

As shown in fig. 1 and 2, a sewer pipe 02 is led out from a sewer opening of a basin 01, after passing through a water return bend 05, one connector of a tee joint is connected to the horizontal sewer pipe 02, the other connector of the tee joint is connected with a shunt pipe 03, a water collecting pipe 08 is connected to the other connector of the tee joint, an electromagnetic valve 07 is arranged on the water collecting pipe 08, the water collecting pipe 08 is connected to the upper part of a water collecting space of a water collector 04 below the basin 1, and the shunt pipe 03 is directly connected to an overflow space 011 of the water collector 04 below the basin 1. An induction area 010 is arranged at the water return elbow 05, and a photoelectric sensor 06 is arranged at the induction area 010.

A liquid level controller 09 is installed in a water collecting tank 012 of a water collector 04, and a secondary water outlet pipe 013 is arranged and connected with a water inlet of a toilet flushing water tank or a pipeline on a secondary water inlet of the front water collector.

The working principle is as follows:

when the water collecting space 012 in the water collector 04 is full of water, the photoelectric sensor installed on the sensing area 010 does not work, the electromagnetic valve 07 is closed, and at this time, the drainage of the basin 01 is directly drained into the shunt pipe 03 from the sewer pipe 02, is drained into the overflow space 011 of the water collector 04 from the shunt pipe 03, and is then directly drained into an outdoor sewer pipe.

When the water collecting space 012 in the water collector 4 is lack of water and needs to be supplemented with water, the liquid level controller 09 gives a water supplementing instruction, at this time, the sensor 06 starts to work to identify the water drainage of the basin 1 and simultaneously controls the opening and closing of the electromagnetic valve 7. When the water quality is turbid and cannot meet the use requirement, the sensor 06 instructs the electromagnetic valve 07 to close, the water directly enters the shunt pipe 03 through the sewer pipe 2, and is discharged into the overflow space 011 of the water collector 04 from the shunt pipe 03 to be directly discharged to an outdoor sewer pipe. When the water quality meets the use requirement, the sensor 06 instructs the electromagnetic valve 07 to open, and then the sewage meeting the use requirement of the basin 01 flows into the water collecting pipe 08 through the sewer pipe 02, flows into the water collector 04 through the water collecting pipe 08, and enters the water collecting space 012 after being filtered.

When the water collecting space 012 in the water collector 04 is full, the liquid level controller 09 sends a full water command, at this time, the sensor 06 stops working, and the electromagnetic valve 07 is closed. The above process is circularly carried out.

As shown in fig. 3a and 3b, an embodiment with a secondary water turbidity identification shunt system on the water collector 80 connected to both the washing machine 85 and the bath tub 84 is shown.

The structure of the water collector 80 may be as shown in fig. 3 b: the water collector 80 divides the vessel of the water collector 80 by a partition 801 into a water collecting space 802 and an overflow space 803, the water collecting space 802 occupying two thirds of the total space of the vessel. Above the partition 801, a gap is provided from the upper tank cover 800 of the sump, which forms an overflow channel. The wall of the water collecting space 802 is provided with a water inlet 804, as shown in fig. 3b, the water inlet 804 is connected with a water inlet pipe, the water inlet pipe is connected with two branch pipes which are respectively connected with a drain pipe of the washing machine 5 and a drain pipe of the bathtub 4, a liquid level controller 806 is fixedly arranged in the water collecting space in a staggered way with the water inlet, and a secondary water outlet 807 is arranged on the side wall of the water collecting space. A water collecting space drain opening 808 is provided at the bottom of the partition 801 between the water collecting space 802 and the overflow space 803 of the water collector 80. After the drainage of the washing machine or the bathtub is finished, the remaining secondary water in the water collecting space can flow from the drainage opening to the overflow space in a short time and then be drained by the drainage opening without remaining in the water collector. The bottom of the overflow space is provided with a water outlet 809 connected with a sewer. A water inlet 810 is provided on the cover 800 at a position corresponding to the overflow space 803, where a cannula is provided to be connected to an overflow water port of the bathtub, and before a large amount of water is discharged from the bathtub, the water flowing out from the overflow port of the bathtub enters the overflow space of the water collector 80 and is directly discharged from the sewer.

The water inlet pipe of the water collector 80 is provided with a sensing area 83 (pipeline shape) which is connected with the water collecting area of the water collector 80, and a photoelectric sensor 86 is arranged at the sensing area 83. A check valve 81 and a water pump 82 are arranged on a delivery pipeline connected with a secondary water outlet of the water collector 80, and the delivery pipeline is connected with a front water tank or other water collectors.

The working principle is as follows:

when the front water tank or water collector is full, the photoelectric sensor 86 arranged on the water inlet pipe and the water pump 82 on the conveying pipeline do not work, and at the moment, if the washing machine 85 and the bathtub 84 discharge water, the water flows into the overflow area through the water collecting area of the water collector 80 and then directly flows into an outdoor sewer system.

When the water tank or the water collector in front is lack of water and needs to be supplemented with water, the bathtub 84 and the washing machine 85 have the drained water to flow out and enter the water collector 80, the liquid level controller 806 in the water collector 80 sends a water signal, at the moment, the photoelectric sensor 86 starts to work to identify the drained water, when the water quality does not meet the requirement, the water pump 82 does not work, the water passes through the water collecting area of the water collector 80 and is directly drained to the overflow area, and the water is directly drained to an outdoor drainage system from the overflow area. When the water quality meets the use requirement, the photoelectric sensor 86 sends out an instruction to start the water pump 82 and supply the water to the front water tank or the water collector, when the front water tank or the water collector is full, the liquid level controller in the front water tank or the water collector sends out a full water instruction, the water pump 82 and the sensor 86 stop working, and the water supply stops. The process is repeated cyclically.
