Problems solved by technology

[0003] However, when the gas water heater is turned off, there will be accumulated water in the hot water pipe, so that when the gas water heater is not used for a long time, a large number of bacteria will grow in the hot water pipe
When the gas water heater is used again, the bacteria-containing water retained in the hot water pipe will be provided to the user, causing the user to easily experience symptoms of physical discomfort under the action of bacteria when using water again

Embodiment approach 2

[0072] This embodiment provides a control method for a gas water heater. see Figure 6 , the control method of the gas water heater includes:

[0073] When the gas water heater 1 is in the standby state, execute S300;

[0074] S300: Start the burner 12 and the circulation pump 17, so that the burner 12 circulates and heats the water from the return water pipeline in the heat exchange pipeline 13.

[0075] After the cyclic heating of the burner 12 is completed, S400 is executed.

[0076] S400: Open the water outlet valve 5, so that the water in the return water line is discharged out of the return water line.

[0077] Compared with the prior art, the beneficial effect of the gas water heater control method provided by this embodiment is the same as that of the above-mentioned gas water heater 1 , which will not be repeated here.

[0078] When it needs to be explained, the combustion power of the above-mentioned burner 12 can be selected according to the actual situation. T...

Embodiment approach 3

[0109] This embodiment provides a computer-readable storage medium. The computer-readable storage medium includes computer instructions, and when the computer instructions are run on the processor 16 of the gas water heater 1 , the processor 16 is made to execute the above-mentioned control method.

[0110] Compared with the prior art, the beneficial effect of the computer-readable storage medium provided by this embodiment is the same as the beneficial effect of the above gas water heater control method, which will not be repeated here.

Embodiment approach 4

[0112] This embodiment provides a computer program product. The computer program product includes computer instructions, and when the computer instructions are run on the processor 16 of the gas water heater 1, the processor 16 is made to execute the above-mentioned control method.

[0113] Compared with the prior art, the beneficial effect of the computer program product provided by this embodiment is the same as the beneficial effect of the above gas water heater control method, and will not be repeated here.

[0114] In the description of this specification, specific features, structures, materials or characteristics may be combined in any one or more embodiments or examples in an appropriate manner.

Abstract

The invention discloses a gas water heater and a control method thereof, and relates to the technical field of gas water heaters. The gas water heater is used for sterilizing a hot water pipe and discharging accumulated water containing bacteria in the hot water pipe out of the hot water pipe. The gas water heater comprises a processor, wherein the processor is used for starting a combustor and a circulating pump when the gas water heater is in a standby state so that the combustor can circularly heat water, from a water return pipeline, in a heat exchange pipeline, and after circular heating of the combustor is completed, a water outlet valve is opened so that water in the water return pipeline can be discharged out of the water return pipeline. The control method is used for controlling the gas water heater.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a gas water heater and a control method thereof. Background technique [0002] Gas water heater is a commonly used household appliance, which is mainly used to heat pipe network water to provide domestic hot water for users. When the gas water heater is in use, it is necessary to connect the water inlet joint of the gas water heater with the cold water pipe, connect the water outlet joint of the gas water heater with the water terminal through the hot water pipe, and at the same time connect the cold water pipe with the water terminal. [0003] However, when the gas water heater is turned off, there will be accumulated water in the hot water pipe, so that when the gas water heater is not used for a long time, a large number of bacteria will grow in the hot water pipe. When the gas water heater is used again, the water containing bacteria retained in the hot water pipe will...
