Description
Technical field
The utility model belongs to combustion apparatus, especially belongs to the intelligent power saving kitchen range.
Background technology
The employed cooking stove of catering trade is because its working time is long, and efficient energy-saving gets more and more people's extensive concerning, and present employed cooking stove is as shown in Figure 1; Two identical combustion chambers about generally having, its course of work is for opening fan switch 71-open kindling material switch 72-open ignition switch 73-driving switch 13 to open, and whole process is operated by manual work; The size of complicated operating process, especially combustion gas is controlled by main air valve, and the size of air inlet amount is controlled by blower fan; The two is interlock not; Switch also not at a place, is selected respectively the two by manual work, the main air valve open degree usually can occur and change; Blower fan is not and then change but, and the two does not match and causes combustion gas usefulness to reduce.
Summary of the invention
The utility model purpose is to overcome the shortcoming that existing food and drink cooking stove exists, and a kind of operating process automation is provided, energy-efficient intelligent power saving kitchen range.
The technical scheme that the utility model adopted is a kind of intelligent power saving kitchen range; It comprises combustion chamber, the kitchen range top, blower fan, tap; Its structural feature is that it has the control system that is made up of single-chip microcomputer, operating key, sampling sensor, executive item; Described operating key comprises power switch, starts button, driving switch; Described sampling sensor comprises flame detection sensor, blower fan sensor, and described executive item comprises blower fan, air valve, igniter, and single-chip microcomputer is connected with all operating key, sampling sensor, executive items as control centre.
The utility model is on the basis of existing cooking stove, to introduce single-chip microcomputer as control centre blower fan, air valve, igniter to be handed over its control; Make blower fan by manually becoming Single-chip Controlling, detect the temperature in the combustion chamber by flame detection sensor, and then the control rotation speed of fan; Make combustion process air-fuel ratio blend range rationally, sufficient combustion, energy-conservation, reduce pernicious gas discharge capacity such as CO; In case accident extinguishing, single-chip microcomputer closes gas check valve, avoids gas leakage.
Has processing center, comparator, isochronous controller, IGNITION CONTROL, Air Valve Control, blower fan control in the single-chip microcomputer; Processing center is the core of single-chip microcomputer; Comparator, isochronous controller are connected with processing center respectively, and IGNITION CONTROL, Air Valve Control, blower fan control are connected with isochronous controller respectively, and flame detection sensor is connected with comparator; Power switch, startup button, driving switch, blower fan sensor are connected with processing center respectively; IGNITION CONTROL is connected with igniter, and air valve is connected with Air Valve Control, and blower fan control, blower fan sensor link to each other with blower fan.
Because air valve has different gears; Therefore there is different temperature in the burner hearth; Detect through flame detection sensor, in single-chip microcomputer, be provided with isochronous controller IGNITION CONTROL, Air Valve Control, blower fan are controlled, it except the rotating speed that makes blower fan with driving switch matches; In addition driving switch is controlled: isochronous controller opens firepower air valve II when cutting out firepower air valve I; Otherwise when transferring 1 grade to by 2 grades, isochronous controller opens firepower air valve I when cutting out firepower air valve II.
Sampling sensor has also comprised the pot sensor, and playing the pot sensor is that travel switch and single-chip microcomputer join.The utility model has also increased travel switch as playing the pot sensor, and the contact of travel switch is positioned on pot seat ring.Present to play a pot switch be photoemission, receiver, causes the state that does not receive easily, as: owing to cooking stove environment for use reason, cause the fuzzy of sending and receiving eyeglass and cause the state of not receiving; Can produce erroneous judgement, its reason be behind the pot when people's arm or other objects cover emission with RX path, it is to play pot back, pot replaced that this device can be judged by accident, main flame is lighted immediately, continues the sky burning, still causes energy waste; If the personnel that possibly cause because of carelessness burn.And the stroke of travel switch has been avoided maloperation, only when pot puts down, could shift travel switch onto the end, and travel switch just can be opened.
Flame detection sensor is a thermocouple, and it and igniter all are contained in the combustion chamber, and flame detection sensor is contained in the air outlet position of blower fan, and the two angulation is the 90--270 degree.
Utilize thermocouple to make flame detection sensor, behind flame combustion, produced potential difference at its two ends after thermocouple is heated, flame is big more; The temperature of fire prospecting needle is high more, and the potential difference of generation is big more, and is opposite; Flame is more little, and the temperature of fire prospecting needle is low more, and the potential difference of generation is more little; Single-chip microcomputer judges through setting potential value in the comparator of spare and accessory parts mutually with flame detection sensor, according to flame size, and the control rotation speed of fan, when firepower was big, current potential was big, and rotation speed of fan is big; When firepower hour, current potential is little, and rotation speed of fan is slow; After flame-out, the thermocouple heat radiation is quickened in the air outlet good heat radiating position of blower fan, so that CPU reads the current potential information when stopping working more rapidly.When flame-out, current potential is minimum, works as current potential less than definite value through setting, and the blower fan full speed running is so that dispel the fuel gas that does not have burning in the burner.
