Problems solved by technology
[0002] Existing water heaters do not have the function of providing water at a constant temperature, so if the water temperature is too high, there is a risk of scalding the user
Furthermore, when the amount of water heated by the water heater becomes smaller, and the heating power of the water heater has not decreased in real time as the water amount becomes smaller, the temperature of the hot water in the water heater will fall into an overheating state due to receiving too high heat. area, causing the user to be at risk of scalding due to excessive water temperature
In addition, when the hot water temperature falls into the overheating zone, the user must additionally adjust the mixed cold water, resulting in waste of water resources during the adjustment process

The invention discloses a water inlet throttle valve control method of a water heater and a water heater control method. The water inlet throttle valve control method of the water heater and the waterheater control method are suitable for the water heater comprising a water inlet throttle valve, a heater and a controller, and the water inlet throttle valve comprises a water inlet, a heating wateroutlet and a bypass water outlet. The control method comprises the steps that the previous flow and the current flow of the water inlet are obtained, the flow ratio is calculated, the temperature value of cold water flowing through the water inlet throttle valve is obtained, the temperature value of hot water is obtained, when the temperature value of the hot water falls into an overheat area orthe flow ratio is larger than 1, and the controller calculates the flow dividing ratio and controls the flow of the bypass water outlet to be the product of the flow of the water inlet and the flow dividing ratio. According to the water inlet throttle valve control method of the water heater and the water heater control method, by detecting the temperature value of the hot water in the water heater and the temperature value of the cold water flowing into the throttling valve, the flow dividing ratio is calculated according to the temperature value of the hot water, the temperature value of thecold water and the default temperature value so as to control the flow of the cold water flowing out of the bypass water outlet, the risk that a user is scalded due to too high water outlet temperature is avoided, and water wasted when the user adjusts and controls the water temperature by himself / herself is saved.
Description
technical field [0001] The invention relates to a control method of a water heater, in particular to a control method of a water inlet throttle valve of the water heater. Background technique [0002] Existing water heaters do not have the function of providing water at a constant temperature, so if the water temperature is too high, there is a risk of scalding the user. Furthermore, when the amount of water heated by the water heater becomes smaller, and the heating power of the water heater has not been reduced in real time as the water amount becomes smaller, the temperature of the hot water in the water heater will fall into an overheating state due to receiving too high heat. area, causing the user to be at risk of scalding due to the high temperature of the outlet water. In addition, when the temperature of the hot water falls into the overheating zone, the user has to additionally adjust the mixed cold water, resulting in waste of water resources during the adjustmen...
