Abstract

The invention discloses a pipeline system of a gas water heater and a control method. The system comprises a gas water heater body, a water return pump, a temperature sensor, a water return branch pipe and a one-way valve arranged on the water return branch pipe, and the water return pump and the temperature sensor are both arranged on a water inlet pipeline of the gas water heater body; the waterreturn branch pipe is used for being connected with an external hot water pipe and an external cold water pipe of the gas water heater body to form a water return pipeline; the pipeline system further comprises a water flow sensor, a pipeline control assembly and a controller; the water flow sensor is arranged at the cold water end of an external water point and used for detecting the water flowof the cold water end of the external water point; the pipeline control assembly is arranged on the water return branch pipe, and the pipeline control assembly is used for preventing the condition that the water flow in the water return branch pipe reaches the starting flow of the gas water heater body due to the fact that water is used at the cold water end of the external water using point; andthe controller is electrically connected with the water flow sensor and the pipeline control assembly.

Description

technical field

[0001] The invention relates to the technical field of gas water heaters, in particular to a pipeline system and a control method of a gas water heater. Background technique

[0002] Existing zero-cold water gas water heaters are usually divided into three-pipeline schemes (hot water pipes, cold water pipes, return water pipes) and two-pipeline schemes (hot water pipes, cold water pipes). The branch pipe and the one-way valve connect the cold and hot water pipes. When you turn on the cold water faucet of the sink, flushing the toilet, showering cold water or washing machine, there is usually a problem of self-starting of the gas water heater, especially when flushing the toilet. When the toilet is flushed, it will self-start for a short time. After the toilet is flushed, there will be no water flow through the gas water heater, and the gas water heater will automatically shut down. In addition to the noise caused by frequent self-starting (the ignition noise ...
