Abstract

The invention discloses a control method of a gas water heater. The control method includes the steps that a set heat value is determined; data collection time is set, timing begins from starting of the gas water heater, and the heat values in the data collection time are calculated every other the set data collection time; the total heat value is obtained by sequentially adding of the heat valuesobtained through calculation; and the total heat value is compared with the set heat value, and the gas water heater is controlled to work according to a comparison result. By means of the control method of the gas water heater, the problem that oxygen defect flameout protection in an existing water heater is limited by the space can be solved to a certain degree.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a control method for a gas water heater. Background technique [0002] In related technologies, the use of gas water heaters is inseparable from oxygen. The heat energy released by the reaction between oxygen and natural gas or liquefied petroleum gas heats water. When the oxygen supply is insufficient, the gas water heater will automatically turn off and stop working to prevent accidents. At present, the oxygen-deficiency flameout protection methods of gas water heaters after hypoxia mainly include the combination protection mode of thermocouple and solenoid valve and the automatic flameout protection mode of 40 minutes (or other time set by the program), among which the combination protection mode of thermocouple and solenoid valve The main principle is to detect the size of the flame by the thermocouple and output different thermoelectric potentials to control the openin...
