Water filtering and storage system with internal circulation

Abstract

This invention relates to an internal circulation filtration and water storage system, comprising a water storage tank, a filter module, three drive modules, and a control unit. The filter module is located between an inlet and the water storage tank. Each drive module includes a pump and a motor. The control unit is electrically connected to the motor of each drive module. The three drive modules are an inlet module, an internal circulation module, and an outlet module. The pump of the inlet module drives water from the inlet through the filter module into the water storage tank. The pump of the outlet module drives water from the water storage tank to an outlet. The pump of the internal circulation module is connected to the water storage tank through an internal circulation pipeline and drives water from the water storage tank through the internal circulation pipeline back to the water storage tank. Each drive module has a first pressure switch, which is connected to the pump and located in the circuit between the motor and the power supply.

Claims

1. An internal circulation filtration and water storage system, comprising an inlet and an outlet, and including: a water storage tank; a filter module disposed between the inlet and the water storage tank, and including a plurality of filters; three drive modules, each drive module including a motor and a pump connected to it, and the three drive modules being an inlet module, an internal circulation module, and an outlet module, respectively; the pump of the inlet module is disposed between the inlet and the water storage tank, and can be powered by the motor to drive water from the inlet through the plurality of filters into the water storage tank; the pump of the internal circulation module is connected to the water storage tank through an internal circulation pipeline, and can be powered by the motor to drive water from the water storage tank through the internal circulation pipeline and back into the water storage tank; The pump of the water outlet module is located between the water storage tank and the water outlet, and is powered by the motor to drive water from the water storage tank to the water outlet; and a control unit is electrically connected to the motors of the three drive modules; wherein... Each of the drive modules is equipped with a first pressure switch, which is connected to the pump and located in the circuit between the motor and a power supply. When water enters the pump through the first pressure switch, the first pressure switch connects the circuit.

2. The internal circulation filtration and water storage system as described in claim 1, wherein the water inlet module is provided with a second pressure switch, the second pressure switch is located on the circuit of the motor and the power supply, the top of the water storage tank is connected to the second pressure switch through a pipe, and when water flows from the water storage tank through the second pressure switch, the second pressure switch disconnects the circuit.

3. The internal circulation filtration and water storage system as described in claim 1, wherein each of the drive modules is provided with a pressure reducing valve before the pump, so that water enters the pump after passing through the pressure reducing valve.

4. The internal circulation filtration and water storage system as described in claim 1, wherein one of the filters of the filtration module is located between the pump of the inlet module and the inlet, and the remaining filters are located between the pump of the inlet module and the water storage tank.

5. The internal circulation filtration and water storage system as described in claim 1, wherein a manual valve is provided between the water storage tank and the pump of the internal circulation module and the pump of the water outlet module.

6. The internal circulation filtration and water storage system as described in claim 1, comprising an operation button electrically connected to the control unit, wherein when the operation button is operated, an electrical signal is transmitted to the control unit, causing the control unit to control the motor of the internal circulation module to operate for eighty minutes, stop for twenty minutes, and then operate for another eighty minutes.

7. The internal circulation filtration and water storage system as described in claim 6 includes two status indicator lights, which are electrically connected to the control unit. When the control unit controls the motor of the internal circulation module to operate, it controls one of the status indicator lights to light up. When the control unit controls the motor of the internal circulation module to stop, it controls the other status indicator light to light up.

8. The internal circulation filtration and water storage system as described in claim 1, wherein the water storage tank is equipped with a level switch, which is located on the circuit between the motor of the water inlet module and a power supply unit. When the water level in the water storage tank rises to a certain height, it can be detected by the level switch, causing the level switch to disconnect the circuit.

9. The internal circulation filtration and water storage system as claimed in claim 1, wherein the water storage tank is provided with a plurality of filter screens inside, so that the water in the water storage tank flows through the plurality of filter screens respectively when it flows to the internal circulation pipeline of the internal circulation module and the pump of the water outlet module.
