Disclosure of Invention

The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

To this end, an aspect of the present invention is to provide a control method of a water heater.

Another aspect of the present invention is to provide a control system of a water heater.

In yet another aspect of the present invention, a water heater is provided.

Yet another aspect of the present invention is to provide a computer apparatus.

Still another aspect of the present invention is to provide a computer-readable storage medium.

In view of this, the present invention provides a control method of a water heater, the control method of the water heater includes: detecting the water inlet temperature of a water inlet pipe of the water heater; acquiring a power value of a heating component of the water heater according to the water inlet temperature; and controlling the heating assembly to heat according to the power value, so that after the hot water pipe in the heater and the water in the water inlet pipe are mixed, the water outlet of the water heater meets the preset water consumption of the preset water outlet temperature interval.

According to the control method of the water heater, firstly, the water inlet temperature of the water inlet pipe of the water heater is detected, the water inlet temperature is set to be T2, and the water inlet temperature is not constant under the influence of external factors such as different seasons, different weather, different regions or different water sources, so that the power value of the heating component of the water heater is obtained according to the detected water inlet temperature, the heating component is controlled to heat according to the obtained power value to obtain hot water with the temperature of T1, when a user needs to bath, the water mixing valve of the water heater mixes the hot water with the temperature of T1 with cold water with the temperature of T2, warm water with preset water consumption in a preset water outlet temperature interval is obtained, the preset water outlet temperature at the moment is preferably between 32 ℃ and 42 ℃, and the preset water consumption is preferably between 65L and 75L. So long as can guarantee that the water heater can last out when predetermineeing the water temperature and be the warm water of predetermineeing the water consumption after mixing, can not be complete with the heating temperature (generally 75 ℃) when heating to normal bathing with the courage internal water heating of water heater, avoid on the one hand needing the heating overlength and cause the user to wait for too long problem, on the other hand still avoid when bathing water consumption demand is less, with the extravagant problem that the excessive high temperature of whole courage water heating appears, the water consumption of predetermineeing the water temperature interval is satisfied to the water yield of yielding when bathing like this, can control heating element and heat according to a lower power like this, promoted the speed of boiling water, avoided the extravagant problem of hot water.

It is conceivable that the preset water outlet temperature may be obtained according to measurement of the water outlet temperature of the user during daily bathing, and the preset water consumption may be obtained according to water consumption of a person during daily bathing, so that it is avoided that the preset value set cannot meet all user demands.
