Embodiment Construction
[0036] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0037] The main solution of the embodiment of the present invention is:
[0038] regularly obtain the water temperature in the water tank of the water heater;
[0039] When the water temperature is obtained, it is judged whether the water temperature drops according to the currently obtained water temperature and the last obtained water temperature;
[0040] When the water temperature drops, and the number of drops of the water temperature within a preset time period is greater than the preset number of drops, it is determined that the water heater is in a state of using water.
[0041] In the prior art, at present, in the structure of the water heater, flow sensors or flow switches are generally used to detect whether water is used, and the price of these two devices is relatively high, and they have a high impact o...

The invention discloses a water consumption detection method of a water heater. The water consumption detection method of the water heater comprises the steps that the water temperature in a water tank of the water heater is obtained regularly; when the water temperature is obtained, whether the water temperature drops or not is judged according to the currently obtained water temperature and thewater temperature obtained last time; and when the water temperature drops and the drop frequency of the water temperature in the preset time period is larger than the preset drop frequency, it is judged that the water heater is in a water consumption state. The invention further discloses the water heater, a water consumption detection system of the water heater and a computer readable storage medium. When the water temperature of the water heater is detected, whether the water heater is in the water consumption state or not is judged according to the drop frequency of the water temperature,the purpose that water consumption detection can be conducted only through a temperature sensor is achieved, and installation of devices such as a flow sensor is avoided, so that the manufacturing cost of the water heater is reduced.
Description
technical field [0001] The present invention relates to the technical field of water heaters, in particular to a water heater and its water detection method, system, and computer-readable storage medium. Background technique [0002] During the use of the water heater, it is often necessary to detect whether the user is currently using water, for example, to control the temperature compensation function of the water outlet according to the water consumption status, that is, during the water use process, because the outlet water temperature is lower than the set temperature, it is necessary to activate the water outlet near the water outlet. The heating rod is used for heating, and for example, the water heater is controlled to be heated in advance according to the time rule of the user's water consumption, so as to make the water heater intelligent. [0003] At present, in the structure of water heaters, flow sensors or flow switches are generally used to detect whether wate...
