The gas water heater supplies hot water through the thermal circulation pipeline so as to heat users, wherein the water in the thermal circulation pipeline contains calcium and magnesium ions, and when the water is heated in a circulating way, the calcium and magnesium ions are easy to form scale in the inner wall of the pipeline, so that the heat exchange efficiency of the circulation pipeline is low. Therefore, the scale needs to be cleaned. At present, after-sales maintenance personnel are used for cleaning by going on the door, the water outlet connecting pipe is detached firstly, then the water inlet valve is opened, and the scale in the warm pipeline is washed by water, so that the cleaning mode is very inconvenient, labor and effort are wasted, and the cleaning effect is poor.

In this way, the cleaning system for the gas water heater provided by the application can realize self-cleaning of scale in the circulating pipeline without disassembling the water outlet connecting pipe, and improves the cleaning convenience and the cleaning effect.

Referring to fig. 1 to 3, a cleaning system 100 for a gas water heater according to an embodiment of the present application includes a water circulation assembly and a cleaning assembly.

The water circulation assembly includes a circulation line 10 and a water pump 20 provided on the circulation line 10, and the circulation line 10 includes a venturi tube 11. The cleaning assembly includes a cleaning vessel 30, the cleaning vessel 30 including a cleaning agent chamber 31 and a liquid suction port 31a and a liquid suction port 31b communicating with the cleaning agent chamber 31, a drain chamber 32, and a drain inlet 32a and a drain outlet 32b communicating with the drain chamber 32, the liquid suction port 31b and the drain inlet 32a each being in selective communication with the throat suction port 11a of the venturi tube 11.

The circulation line 10 is used to communicate with a user load, which may be, for example, a radiator, a floor heating pipe, or the like. When the water pump 20 is operated, the water in the circulation line 10 is returned to the circulation line 10 after heat exchange by the user load, thereby forming a water circulation.

The venturi tube 11 has an inlet 11b, an outlet 11c and a throat suction port 11a communicating with each other. The venturi tube 11 is provided as a part of the circulation line 10, and during water circulation, water flows from the inlet 11b through the inner cavity of the venturi tube 11 and out the outlet 11c, during which a negative pressure is generated at the throat suction port 11a due to the structural characteristics of the venturi tube 11 to suck the detergent in the detergent chamber 31. The cleaning agent may be injected into the cleaning agent chamber 31 from the filling port 31a to be stored.

The drainage chamber 32 provides a drainage channel for cleaned sewage, which may enter the drainage chamber 32 from the drainage inlet 32a and drain from the drainage outlet 32 b.

For example, when it is necessary to clean the scale, the communication passage between the liquid suction port 31b and the throat suction port 11a of the venturi tube 11 is opened to communicate with each other, the communication passage between the drain inlet 32a and the throat suction port 11a of the venturi tube 11 is opened to communicate with each other, water circulates in the circulation line 10 by the action of the water pump 20, when the water flow passes through the venturi tube 11, the throat suction port 11a generates negative pressure to suck the cleaning agent in the cleaning agent chamber 31 into the circulation line 10, then the communication passage between the liquid suction port 31b and the throat suction port 11a of the venturi tube 11 is opened to clean the scale in the circulation line 10, for example, for 10 minutes, then the communication passage between the drain inlet 32a and the throat suction port 11a of the venturi tube 11 is opened to communicate with each other, and the cleaned sewage enters the drain chamber 32 via the throat suction port 11a and the drain inlet 32a to finally be discharged from the drain outlet 32 b.

In the above technical scheme, when water in the circulation pipeline 10 passes through the venturi tube 11, the negative pressure generated by the throat suction inlet 11a of the venturi tube 11 sucks the cleaning agent in the cleaning agent cavity 31 into the circulation pipeline 10 for circulation cleaning, and the cleaned sewage is discharged from the drainage cavity 32, so that the scale self-cleaning is realized without disassembling the pipeline, and the cleaning convenience and the cleaning efficiency are improved.

In some embodiments, the cleaning assembly includes a three-way connection 33 and a first solenoid valve 34 and a second solenoid valve 35 disposed on the three-way connection 33. The first port of the three-way joint 33 communicates with the throat suction port 11a of the venturi tube 21, the second port of the three-way joint 33 communicates with the liquid suction port 31b, and the third port of the three-way joint 33 communicates with the discharge port 32 a. The first solenoid valve 34 is used to open or close a communication passage between the first port and the second port so that the suction port 31b and the throat suction port 11a can be selectively communicated, and the second solenoid valve 35 is used to open or close a communication passage between the first port 33a and the third port so that the drain inlet 32a and the throat suction port 11a can be selectively communicated.

In the above technical solution, the three-way joint 33 and the first electromagnetic valve 34 and the second electromagnetic valve 35 arranged on the three-way joint 33 form a modularized unit, and the installation and the maintenance are convenient.

The first solenoid valve 34 and the second solenoid valve 35 may be electrically connected to a controller, and automatic opening or closing of the first solenoid valve 34 and the second solenoid valve 35 is achieved through configuration of the controller.

Further alternatively, the second port communicates with the liquid suction port 31b through the first hose 362. The third port communicates with the drain inlet 32a through a second hose 361. The first hose 362 and the second hose 361 are easy to install, connect, maintain and disassemble.

It will be appreciated that the cleaner chamber 31 and the drain chamber 32 are two separate chambers which are not in communication. For example, the partition plate 37 abuts against the inner top wall, the inner bottom wall and the inner peripheral wall of the cleaning container 30, thereby constituting two chambers that are isolated from each other.

In some embodiments, the water circulation assembly includes a heat exchanger 40, and the circulation line 10 includes a water inlet pipe 12 and a water outlet pipe including a first water outlet pipe segment 131 and a second water outlet pipe segment 132.
