Document Type and Number:
WIPO Patent Application WO/2022/160882
Kind Code:
A1
Abstract:
A warm boiled water machine (10) able to perform precise temperature adjustment, and a milk brewing machine comprising the warm boiled water machine (10). The warm boiled water machine (10) comprises a segmented control heater (100), a heat exchanger (200), and an electronic control system (300); the segmented control heater (100) comprises a heating base body (110) which has a plurality of heating areas (111) and a water passage member (120) which has a plurality of water passage areas (121), each heating area (111) being provided with a heating body (112) and a temperature sensor (113); pre-heated cold water from a sub-heater is introduced into a cold water channel (220) of the heat exchanger (200), an outlet end of the cold water channel (220) conveys a water source to another sub-heater, and a hot water channel (230) of the heat exchanger (200) accepts boiled water that has undergone heating by a sub-heater and exchanges heat with cold water within the cold water channel (220) so as to output warm water; the electronic control system (300) comprises a switch circuit (320), a power supply circuit (330), and a main control circuit (310) connected to each of the temperature sensors (113), the power supply circuit (330) comprises a voltage input circuit (331), a voltage transforming circuit (332), an optical coupling circuit (333), a voltage processor (334), and a rectifier circuit (335), and a main control chip (311) controls a voltage value that the rectifier circuit (335) outputs to a heating body (112) so as to adjust the heating temperature of the heating body (112).
