Preheating method and device for water heater and water heater

Abstract

The invention discloses a preheating method and device used for a water heater and the water heater. The preheating method comprises the steps that corresponding relationships between the environment temperature of the environment where the water heater is located in each period of time during a past preset cycle and water habits are stored; the water habits comprise the highest water temperature and the largest water consumption; the forecast temperature of the environment in each period of time during the preset cycle in the future is obtained; and according to the highest water temperature and the largest water consumption corresponding to the environment temperature identical to the forecast temperature in the stored water habits, the highest water temperature and the largest water consumption of the period of time to which the forecast temperature belongs are determined. According to the scheme, the defects that in the prior art, the heating efficiency is low, the temperature control difficulty is high, and the energy-saving effect is poor can be overcome, and the beneficial effects of high heating efficiency, low temperature control difficulty and good energy-saving effect can be achieved.

Description

technical field [0001] The invention belongs to the technical field of water heaters, and in particular relates to a preheating method and device for the water heater and the water heater. Background technique [0002] A water heater refers to a device that raises the temperature of cold water into hot water within a certain period of time through various physical principles. At present, various water heaters such as air energy water heaters, electric water heaters, and solar water heaters are moving toward intelligent control. For example: a water heater intelligent control device disclosed in the prior art is equipped with a WIFI module, a wireless router, and a server, etc., enabling the user to realize real-time control, and can solve simple real-time or remote control of the opening of the air energy water heater, which is convenient to use. [0003] However, with the improvement of consumers' quality of life, while improving the effect of user experience products, the...
