Abstract

The invention discloses an intelligent gas stove with touch type keys and relates to an intelligent and automatic control method of the intelligent gas stove. The control method is as follows: A microcontroller A is used as a core, a touch type keys module B, a non-contact type infrared temperature measuring module C, a combustible gas leakage sensor D and a stove surface temperature detecting thermosensitive resistor E are used for sensing the work state of the gas stove; the word state is fed back to an operator through a display module G and a buzzer J; the whole process is controlled by a program; the ignition operation of an electronic fire maker H, the flame size adjustment of an electromagnetic gas valve I and the switch on or off of gas are all controlled through commands which the program emits. The wok temperature is adjustable; the intelligent gas stove is suitable for cooking of various dishes and has the function of preventing dry burning, fire hazards and gas leakage, the safety performance is greatly improved; the intelligent gas stove adopts the design of a tempered glass panel and the touch type keys, the stove surface is smooth, beautiful, not susceptible to oil stain, easy to wipe, full of modern fashion under the shining of a display light and high in intelligent level and is capable of connecting a network through communication ports.

Description

Touch-key intelligent gas-burning stove

Technical field

The present invention relates to a kind of intelligent automatic control aspect of intelligent automatic control field, especially gas-cooker.

Background technology

The gas-cooker that family uses at present all adopts mechanical switch to control, and the size of flame can only be struck sparks and regulate to this switch, and its shortcoming is: 1, on kitchen range face, there is the knob of a protrusion, and neither attractive in appearance, sticking oil stain again, also bad wiping; 2, can not temperature control, can not timing, control ability is low automatically, cannot meet modern multi-functional, intelligentized culinary art needs, fault-free monitoring and defencive function, security is poor.

Summary of the invention

In order to overcome above-mentioned defect, the present invention adopts the method for singlechip technology and automatic electronic control, realizes the basic function of gas-cooker is controlled, the particularly sparking function of gas-cooker, flame size regulatory function, the control function of temperature of boiler, timing cooking function, the automatic control function that fire-proof, anti-gas-leak are hurted sb.'s feelings in addition etc., and adopt touch-key design, make kitchen range face smooth, no concave-convex, easy to clean, kitchen range face is attractive in appearance, showing that under the shining of light, tool is born modern sense.

The technical solution adopted for the present invention to solve the technical problems is: the technology such as application single-chip microcomputer and touch-key, non-contacting infrared thermometric, sparking to gas-cooker, temperature adjustment, regularly, fault detect and troubleshooting etc. carry out intelligentized control.

Operation principle (seeing accompanying drawing 1):

Fig. 1 is the control system schematic diagram of gas-cooker, and A is single-chip microcomputer, and single-chip microcomputer, by the operation of program, is controlled input-output unit.In the time that B touch-key has input, program can judge it is what instruction, operates according to instruction.The elementary instruction that general gas-cooker will operate has: switch combustion gas, gas ignition, adjusting flame size etc., or selection is applicable to the temperature control mode of certain dish.In the time having the instruction of " opening ", I electromagnetic gas valve door is opened, and and then H electronic lighter is lighted a fire to combustion gas, and flame is lighted; In the time having the instruction of " pass ", I electromagnetic gas valve door is closed, fray-out of flame.In the course of work of gas-cooker, C Non-contact Infrared Temperature Measurement module is surveyed temperature of boiler, and detection data feeds back to program, and program can judge according to the culinary art pattern of dish, and decision is the temperature or reduce temperature of will raising, or keeps temperature.Temperature height regulates combustion gas input size by I electromagnetic gas valve door.For safety will arrange a highest threshold temperature, in the time reaching this limiting temperature, program can shut by order work electromagnetic gas valve door, fray-out of flame, thus protection pot body is not burned, or prevent the generation of fire.D combustible gas leakage sensor and E range surface temperature detect thermistor for safety designed, in the time having gas leakage or range surface temperature exceed when setting value and all can start work electromagnetic gas valve goalkeeper combustion gas and close, and make J buzzer sounding alarm, reach the object of safety kitchen range.G display module can show the duty of gas-cooker, and duty feeds back to operator by sound, light form.K network interface, for attachment networking is established.F power acquisition, with rechargeable battery and civil power and by mode, ensures that gas-cooker under any circumstance can normally use, minimum because of the power consumption of single-chip microcomputer, and also can be arranged under power-down mode and work, thereby consume energy and can ignore.

The invention has the beneficial effects as follows: kitchen range face is attractive in appearance easily wiping; Intelligent par is high, and pot temperature is controlled, is applicable to the culinary art of various dish, can do internet-of-things terminal; The functions such as dry combustion method, fire-proof, anti-flaming leakage of setting up defences, security improves greatly.

Detailed description of the invention

The present invention can transform with the toughened glass panel gas-cooker of selling on the market at present.

Selecting toughened glass panel is because toughened glass panel has attractive in appearance, easy wiping, can realize again the feature of the installation of soft-touch control, and transparent glass texture can make guidance panel seem modern sense very much, and printing word icon, light demonstration etc. all seems very beautiful.

The air valve of gas-cooker is used instead to electromagnetic gas valve door, and electromagnetic gas valve is convenient to automatically controlled, can realize well the function of switch combustion gas and adjusting flame temperature.Igniting can be used electronic lighter.Control system is made a unit box, is arranged on the next applicable position of safety glass.Non-contact Infrared Temperature Measurement module adopts TN series infrared measurement of temperature module, is installed under gas-cooker chassis, and probe is by the circular hole at Zao Yan center, and direct detection is to the temperature of center, the bottom of a pan.Combustible gas leakage sensor and temperature detection thermistor are embedded in the easiest perception gas leakage of toughened glass panel and the place being heated, and enable the existence of full out perception danger.Combustible gas leakage sensor can adopt semiconductor gas sensor, as MQ-4 type or 2M007 type etc.Display module, the mode of available light emitting diode, charactron, in order to display button state and running state of programs.Network interface only does reserved, wouldn't use.Power Management Design is for charging and civil power and by mode, and guarantee under any circumstance can normally be used, at ordinary times not the used time in single-chip microcomputer power-down mode, with the largest the electric energy of saving.Single-chip microcomputer can use STC12C5A60S2, and the program flow chart of single-chip microcomputer is shown in accompanying drawing 2.
