Control method and system of water heater and water heater

Abstract

The invention provides a control method and system of a water heater. The control method of the water heater comprises the steps that the inlet water temperature of a water inlet pipe of the water heater is detected; a power value of a heating assembly of the water heater is acquired according to the inlet water temperature; and the heating assembly is controlled to conduct heating according to the power value so that the outlet water quantity of the water heater can be equal to the preset water supply quantity at the preset outlet water temperature interval after water in a hot water pipe andwater in the water inlet pipe of the water heater are mixed. According to the control method of the water heater, as long as the situation that the water heater can continuously supply warm water atthe preset outlet water temperature and with the preset water supply quantity after water mixing is accomplished can be guaranteed, water in a container of the water heater can be incompletely heatedto enable the temperature to be equal to the heating temperature in the normal bathing process, and therefore the heating assembly can be controlled to conduct heating according to the low power, thewater heating speed is increased, and the phenomenon of waste of hot water is avoided.

Description

technical field [0001] The present invention relates to the field of water heaters, in particular to a water heater control method, a water heater control system, a water heater, a computer device and a computer-readable storage medium. Background technique [0002] At present, the heating modes of conventional electric water heaters on the market include full-tank heating and half-tank heating. When the water is less, there is still the problem of longer heating time. In addition, when the bathing water is less, the existing heating method will either cause too much hot water to run out, resulting in waste of hot water, or insufficient water, resulting in unwashed baths. There is no hot water at all. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art. [0004] Therefore, one aspect of the present invention is to provide a water heater control method. [0005] Another asp...
