System and method for automatic detergent dispensing

Abstract

This invention provides an automatic detergent dispensing system and method, comprising: a control module for allowing users to program various instruction functions into a programming language and write them into built-in memory; at least one human-machine interface electrically connected to the control module for user operation and control via the human-machine interface, and displaying multiple washing function settings; a raw material dispensing unit having multiple pipelines and multiple solenoid valves and electrically connected to the control module; and multiple peristaltic pump units electrically connected to the control module.

Claims

1. An automatic detergent dispensing system, comprising: a control module for providing users with the ability to program various instruction functions into a programming language and write them into built-in memory, and the control module being electrically connected to a power supply to convert input electrical energy into multiple voltages and output them separately; at least one human-machine interface electrically connected to the control module for providing users with the ability to operate and control the system, and displaying multiple washing function settings; a material dispensing unit having multiple pipelines and multiple solenoid valves and being electrically connected to the control module; and multiple peristaltic pump units electrically connected to the control module, each of the peristaltic pump units having a peristaltic tube with one end connected to one end of the pipelines, and the peristaltic pump units extracting multiple detergents and then delivering the detergents to multiple washing machines through the material dispensing unit.

2. The detergent automatic dispensing system as claimed in claim 1, wherein the detergent automatic dispensing system further comprises: a plurality of detergent storage units, each having at least one feed pipe and the detergent storage units storing the detergents respectively, and the feed pipes being connected to the peristaltic pump units through the peristaltic tube.

3. The detergent automatic dispensing system as described in claim 1, wherein the detergent automatic dispensing system further includes: a flushing device connected to the pipes and electrically connected to the control module, and controlling the opening and closing of the solenoid valves through the control module, wherein when the solenoid valves are opened, the flushing device allows tap water to flow into the pipes to clean and remove the detergent residue in the pipes.

4. The detergent automatic dispensing system as described in claim 1, wherein the control module further includes: a wireless communication unit that transmits communication protocol signals to the human-machine interfaces.

5. The detergent automatic addition system as described in claim 1, wherein the control module further includes: a foolproof unit, which can be set to a signal interruption period, wherein if the peristaltic pump units deliver the detergent for a period exceeding the signal interruption period, a signal interruption command is transmitted to the control unit to stop a material delivery signal and to stop the peristaltic pump units from operating.

6. The detergent automatic dispensing system as described in claim 2, wherein the control module further includes: at least one alarm unit that, when the amount of detergent in the detergent storage units is insufficient for cleaning, transmits an alarm command to the control unit to receive and generate an alarm, wherein the alarm includes at least one of a light alarm and an audible alarm.

7. The detergent automatic addition system as described in Request 1, wherein the control module is a Programmable Logic Controller (PLC).

8. The detergent automatic addition system as described in claim 1, wherein the detergents include: a main detergent, a detergent additive, hydrogen peroxide, bleach, and a fabric softener.

9. A method for automatically adding detergent, performed in any one of claims 1 to 6, comprising the following steps: operating at least one human-machine interface, wherein when the at least one human-machine interface receives an instruction for a washing mode, the instruction for the washing mode is transmitted to a control module, the control module receiving and generating a washing signal; activating a plurality of peristaltic pump units, wherein the washing signal from the control module causes the plurality of peristaltic pump units to start, and the peristaltic pump units extract a plurality of detergents; and conveying a plurality of detergents through a plurality of pipelines of a raw material distribution unit and the control module causing a plurality of solenoid valves to open, thereby conveying the detergents to a plurality of washing machines.

10. The automatic detergent dispensing method as described in claim 9, wherein the automatic detergent dispensing method further includes the following steps: removing detergent by a flushing device allowing tap water to flow into the pipes to clean and remove any residual detergent in the pipes.
