Abstract

The invention discloses a liquid heating device with adjustable power and a power control circuit of the device. The liquid heating device and the power control circuit are applied to the fields of liquid heaters such as electric water boilers and electric water heaters. The power can be adjusted automatically and intelligently according to different heating stages of the device. A group of relays and a group of three-terminal bidirectional silicon-controlled switches are connected in parallel on a circuit board, and switching and alternative use of the three-terminal bidirectional silicon-controlled switches and the relays are intelligently controlled in the heating stages of the liquid heating device according to an embedded chip calculation result. Therefore, when the liquid heating device operates under full power, the relays with low cost are switched to control opening and closing of a heating device. When the liquid heating device operates under low power, the three-terminal bidirectional silicon-controlled switches with small current are switched to control opening and closing of a heating pipe. The device achieves a power adjustable function, has high reliability, is low in cost and reduces energy consumption by means of calculation of software, an embedded intelligent chip and a control circuit, so that the liquid heating device avoids multiple boiling and effects of heavy metal produced in the multiple boiling on health.

Description

technical field [0001] The patent of the present invention relates to a liquid heater device, specifically, to an electric water heater and drinking water machine that can intelligently adjust the power in different heating operation stages by combining a relay and a three-stage bidirectional thyristor into a power control group. machine and its control circuit and control method. Background technique [0002] The current working states of liquid heaters such as electric water dispensers and water dispensers are generally divided into a heating stage and a heat preservation stage. In the heating stage, the water heating reaches the maximum setting temperature and stops, and enters the heat preservation stage. In the heat preservation stage, the water temperature is kept within the specified range by controlling the heating device to generate heat or stop generating heat. At present, no matter in the heating stage or the heat preservation stage of this type of product, the ...
