Embodiment Construction

[0011] The present invention refers to the attached Figure 1 to Figure 4 design production;

[0012] figure 1 As shown, the figure includes:

[0013] Microcomputer controller; power-down detection circuit; temperature detection circuit: reset circuit; clock circuit; sound prompt circuit; display circuit; output circuit; key input circuit; power supply circuit.

[0014] The signals of the power-down detection circuit, the temperature detection circuit, the reset circuit and the key input circuit are respectively sent to the 19th pin; the 20th pin; the 13th pin; the 3rd, 4th, and 17th pins of the microcomputer controller IC2. The output signal of the microcomputer controller IC2 is sent to the display circuit through pin 1 and pin 2; it is sent to the sound prompt circuit from pin 7; it is sent to the output circuit from pin 15 and pin 16, and the output circuit is connected to the heating plate control Main and auxiliary heating plate. The above circuit is mounted on a cir...

Abstract

Electric hot water bottle computer controller comprises hardware part and software part. The hardware part including the processor controller, power failure detection circuit and key entry circuit etc. sends the detected signals to controller. Then the controller sends signals to display circuit, sound hint circuit and output circuit to control the basic heating disk and auxiliary heating disk. Dynamic method for determining boiling point is used in the software so as to be able to determine boiling point of water at different air pressure. Thus, production technique is simplified and cost islowered. Power failure detection function makes better functions.

Description

technical field [0001] The invention relates to a computer controller for an electric thermos bottle, in particular to a computer controller for an electric thermos bottle with the function of automatically detecting power failure, and belongs to the field of electronic technology. Background technique [0002] After searching, I found two kinds of computer controllers for electric thermos bottles: [0003] 1. Check the "China Scientific and Technological Achievements Database" in the related literature "Fuzzy Control Electric Hot Water Bottle". The fuzzy control chip of the electric hot water bottle of this achievement has water dry protection and dumping overflow device. Under different atmospheric pressures, its working point can be realized without readjustment water boiling; [0004] 2. Related literature "Intelligent Full Air Pressure Control Device for Electric Hot Water Bottle" Chinese Patent No. CN2385647Y, this invention uses an external resistor and capacitor RC ...
