Title:
CONTINUOUS PREPARATION METHOD FOR BOILING WATER BASED ON GAS-LIQUID TWO-PHASE OBJECT DETECTION
Document Type and Number:
WIPO Patent Application WO/2023/173488
Kind Code:
A1
Abstract:
A continuous boiling water preparation system and a preparation method, based on gas-liquid two-phase object detection. The preparation system comprises a flow regulator (1), a heater (2), a temperature sensor (4), a two-phase object detection sensor (5), and a controller (3); the flow regulator (1) is used to inject a cold water flow obtained from outside into a water inlet of the heater (2); the heater (2) heats up according to heating power provided by the controller (3); the two-phase object detection sensor (5) and the temperature sensor (4) are connected behind the water outlet of the heater (2), and when a boiling water flow flows through the two-phase object detection sensor (5) and the temperature sensor (4), a gas-liquid ratio signal and a temperature signal, respectively, are obtained and transmitted to the controller (3); the controller (3), upon receiving the gas-liquid ratio signal, transmits a signal indicating a required heating power to the heater (2), or transmits a signal indicating a required flow value to the flow regulator (1), to execute output. The gas-liquid ratio signal serves as a closed-loop feedback signal in the continuous preparation of boiling water, ensuring that the user receives actually boiling water while retaining the advantages of current rapid-heating water dispensers.
