Problems solved by technology
[0004] However, this fixed-time shift heating method will cause inconvenience
When the water flow rate of the gas water heater is low (that is, when the user uses less water), using a high-grade heating power (such as 12KW) will cause the water temperature in the gas water heater to rise too high. If the user stops using water for a period of time and uses it again When using hot water, you may be scalded by the hot water provided by the gas water heater
[0005] It can be seen that the shifting heating mode of the existing gas water heater may cause potential safety hazards
Moreover, when the water in the gas water heater rises to a certain temperature, it is of little practical significance to use high power for heating, and it will lead to waste of resources

Embodiments of the present invention provide a safety protection method and device for a water heating device. The method includes: acquiring the real-time detected water outlet flow rate of the water heating device, and comparing the water outlet flow rate with a preset value of the water outlet flow rate; The heating power of the heating device is adjusted to the lowest gear. Since the heating power of the water heating device can be adjusted to the minimum when the water flow rate is low, that is, when the user uses less water, so as to prevent the water from being rapidly heated to a higher temperature, the water heating device provided by the embodiment of the present invention The safety protection method can effectively prevent the user from being scalded by the high outlet water temperature of the water heating device, thereby eliminating potential safety hazards.
Description
technical field [0001] The invention relates to the technical field of water heating, in particular to a safety protection method and device for a water heating device. Background technique [0002] Existing water heating devices, such as common gas water heaters, are usually provided with several heating gears, and the heating power of each gear is different. [0003] For example, a certain type of gas water heater on the market has three levels of heating power: 6KW, 10KW and 12KW. When this type of gas water heater is working, the water is heated for a period of time by the power of 12KW, then by the power of 10KW for a period of time, and finally the power of 6KW is used to heat or keep the water warm. [0004] However, this fixed-time shift heating method will cause inconvenience. When the water flow rate of the gas water heater is low (that is, when the user uses less water), using a high-grade heating power (such as 12KW) will cause the water temperature in the gas ...
