Control device of instantaneous heating water jug and control method thereof

Abstract

The invention relates to a control device of an instantaneous heating water jug and a control method thereof. The device comprises a panel type thick film heater and a circuit board, wherein heating resistors and thermistors are arranged on the thick film heater and respectively connected with the circuit board; and the thermistors are arranged on an area adjacent to the peripheral edge of the thick film heater and at least distributed in a whole circle mode or a mode approximate to a whole circle. In the invention, the thermistors for distinguishing procedures are arranged on the circuit board to detect temperature signals of the thick film heater, and then different heating procedures are adopted to guarantee that the thermistors enter a heating state after liquid all covers a heating disk and absorbs partial heat of the heating disk so as to guarantee that the heating disk cannot have dry burning phenomena; and moreover, heating is started after the afterheat of the heating disk issufficiently utilized to preheat liquid, which saves the energy.

Description

technical field [0001] The invention relates to a control device of an instant hot water bottle and a heating control method thereof, and is an improved technology of the control device and the control method of the instant hot water bottle. Background technique [0002] With the improvement of technology, the current instant hot water pot can already meet the requirement of complete boiling, and can produce hot water quickly, for example, within 10 seconds. This kind of heating plate generally uses a thick film heating plate, and the power is relatively large. The temperature rises quickly, and if no water is released, it can quickly rise to more than 200 degrees in a few seconds. But what follows is that because the general thick-film heater is sealed, the heat dissipation is relatively slow. When the kettle is used continuously, the thick-film heater will be relatively hot. If the button is pressed and the heater is heated immediately, the heater will The temperature wil...

Problems solved by technology

But what follows is that because the general thick-film heater is sealed, the heat dissipation is relatively slow. When the hot water bottle is used continuously, the thick-film heater will be relatively hot. If it is heated immediately after pressing the button, the heater will The temperature will rise rapidly, and when the water in the kettle has not had time to cover the entire heating plate, there is a great possibility that the heating plate will dry out. On the other hand, too much energy will be wasted.
