Title:
ELECTRICAL WATER HEATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/133062
Kind Code:
A1
Abstract:
Disclosed is an electrical water heating device, comprising a water inlet pipe (111), a barrel body (104), a barrel cap (110), a base (108), a heater (109), an upper water level controller (101) and a lower water level controller (102). The barrel body (104) comprises a liner (114) and a housing (113). A heating controller (106') and a heat insulating controller (105'), or a heating and heat insulating controller (106) and a heat insulating inductor (105), are arranged within the housing (113) or the base (108). The upper water level controller (101) and the lower water level controller (102) are both electrically connected to a water inlet controller (112) of the water inlet pipe (111). Water supply of the water inlet pipe (111) is controlled by the water inlet controller (112) so as to realize automatic water supply to the device. Each of the heating controller (106') and the heat insulating controller (105') is electrically connected to a temperature inductor (103) and the heater (109). The heating and heat insulating controller (106) is electrically connected to the heat insulating inductor (105), the temperature inductor (103) and the heater (109), respectively. In this way, effective heating to boiling and heat insulating at suitable temperatures can be realized, energy is saved, and harm to the human body by repeatedly boiled water can be avoided.
