The invention discloses an automatic
temperature control water heating device, and relates to the field of
water heating and temperature controlling equipment. The automatic
temperature control waterheating device mainly comprises a thermoelectric power generating piece, an
electromagnet, an armature and a hot water tank with a heating
assembly, wherein a hot end of the thermoelectric power generating piece is arranged on a tank wall of the hot water tank, the thermoelectric power generating piece is communicated with the
electromagnet in a closed mode, the
electromagnet is aligned with a driving end of the armature, and a passive end of the armature is provided with a normally closed first contact switch for controlling opening and closing of the heating
assembly. When a temperature in the hot water tank reaches a set temperature, a magnetic force generated by a current supplied by the thermoelectric power generating piece to the electromagnet can attract the armature to slide, and the passive end of the armature is used for disconnecting the first contact switch; when the temperature in the hot water tank
dose not reach the set temperature, the passive end of the armature is communicated with the first contact switch, therefore the hot water tank can be automatically heated and powered off, and
electric power waste caused by idle burning is avoided. Heating can be carried out in time when water cools, and a
water temperature is kept constant. The automatic
temperature control water heating device is more intelligent, and the technical effects that the structure principleis simple, the control efficiency is high and the device cost is lower are achieved.
