step S200: when the water heater conveys water to the water storage device, the water quantity and the water temperature in the water storage device are obtained.
Specifically, when the water heater delivers water to the water storage device, the control device can receive water quantity and water temperature data acquired by the data acquisition device arranged on the water storage device. Wherein, controlling means can adopt the existing water heater mainboard of water heater, also can adopt independent controller. The water storage device can be a bathtub, a wash basin or a sink, etc. For ease of understanding, the water supply to the tub will be explained below with reference to a water heater.
When a user needs to use the bathtub for bathing, the water heater can be adjusted to the bathtub mode, the water outlet valve of the water heater is opened at the moment, and the water after being heated is conveyed into the bathtub through the water outlet pipe by the water heater. In the process of injecting water into the bathtub by the water heater, the data acquisition device monitors the water quantity and the water temperature of the bathtub in real time and sends the water quantity and the water temperature to the control device to serve as a reference basis for water outlet control of the control module. Wherein, data acquisition device specifically can include level sensor and temperature sensor, and the depth of water and the temperature in the bathtub are monitored respectively to level sensor and temperature sensor, and controlling means combines the depth of water of collection and the bathtub bottom area of storage then can calculate the water yield in the bathtub.

Specifically, after analyzing the relationship between the actual water temperature in the bathtub and the set water temperature, the control device correspondingly adjusts the combustion power of the water heater so as to match the actual water temperature in the bathtub with the set water temperature. For example, if the water temperature is too high, the combustion power of the water heater is reduced, and if the water temperature is too low, the combustion power of the water heater is increased.
According to the water outlet control method of the water heater, when the water heater conveys water to the water storage device, the water quantity and the water temperature in the water storage device are collected, and when the water quantity in the water storage device does not reach the set water quantity, the combustion power of the water heater is adjusted according to the relation between the water temperature collected in real time and the set water temperature, so that the water temperature in the water storage device is matched with the set water temperature, the problem that the water temperature cannot reach the set water temperature when the water quantity in the water storage device reaches the set water quantity is avoided, and the water outlet control method is convenient for.

The control device may also pre-store an allowable error value, and after receiving the set water temperature input by the user, use the sum of the set water temperature and the allowable error value as the upper limit value of the temperature control range, and use the difference between the set water temperature and the allowable error value as the lower limit value of the temperature control range.
step S420: and adjusting the combustion power of the water heater according to the water temperature in the water storage device and the temperature control range so as to enable the water temperature in the water storage device to be within the temperature control range.

Specifically, when the water temperature of the bathtub is larger than the upper limit value of the temperature control range, the control device reduces the opening degree of the gas proportional valve, reduces the gas combustion amount, reduces the combustion power and reduces the water outlet temperature.
Step S424: and when the water temperature in the water storage device is smaller than the lower limit value of the temperature control range, the opening degree of a gas proportional valve of the water heater is increased. Specifically, when the water temperature of the bathtub is smaller than the lower limit value of the temperature control range, the control device increases the opening of the gas proportional valve, increases the gas combustion amount, improves the combustion power and raises the water outlet temperature.
step S426: when the water temperature in the water storage device is within the temperature control range, the opening degree of a gas proportional valve of the water heater is kept unchanged. Specifically, when the water temperature of the bathtub is within the temperature control range, the opening size of the gas proportional valve is kept, the gas combustion amount is stabilized, the combustion power is stabilized, and the water outlet temperature is stabilized.
And correspondingly adjusting the opening degree of a gas proportional valve of the water heater or keeping the opening degree unchanged according to the relation between the acquired actual water temperature and the temperature control range, and the operation is simple, convenient and reliable. In addition, in another embodiment, the step S400 may also be directly comparing the collected water temperature with the set water temperature, decreasing the opening degree of the gas proportional valve when the collected water temperature is higher than the set water temperature, increasing the opening degree of the gas proportional valve when the collected water temperature is lower than the set water temperature, and keeping the opening degree of the gas proportional valve unchanged when the collected water temperature is equal to the set water temperature.
