Abstract

The invention discloses a water heater and a power adjusting method and system. The method comprises the steps that voltage reference values on the two ends of a branch circuit or a trunk circuit of a preset distribution line are obtained; adjusting the power of the load with the known power on the branch circuit, obtaining the voltage at the two ends of the branch circuit or the voltage on the main circuit, and obtaining the voltage change amplitude of the voltage at the two ends of the branch circuit or the voltage on the main circuit relative to the respective voltage reference value; based on the load power adjustment amplitude and the voltage change amplitude, obtaining a corresponding relation between the load power adjustment amplitude and the voltage change amplitude, and obtaining the maximum voltage change amplitude; the current voltage change amplitude is obtained, the current voltage change amplitude is compared with the maximum voltage change amplitude, and when the current voltage change amplitude is not smaller than the maximum voltage change amplitude, the power of the load with the known power is reduced, and / or the power of other loads connected with the load with the known power in parallel is reduced. According to the invention, power adaptive adjustment of the electric appliance can be reliably realized with low cost.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a water heater, a power adjustment method and a system. Background technique [0002] In the household electricity consumption of users, a series of electrical appliances are usually placed according to the use needs of an area. For example, kitchen appliances such as range hoods, refrigerators, microwave ovens, and dishwashers are placed; bathrooms are equipped with water heaters, fan heaters, Yuba, and hair dryers. , washing machines and other electrical appliances. Usually, electrical appliances in the same area use the same distribution line, and an air switch is set on the distribution line to protect the safety of users. [0003] Take the electrical appliances in the bathroom as an example. When the water heater is working, if other high-power electrical appliances are started at the same time, the air switch may be activated, causing the electrical appliances...
