Description
Technical field
The utility model belongs to combustion apparatus, especially belongs to the intelligent power saving kitchen range that can control rotation speed of fan automatically.
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.
On the other hand, blower fan adopts vertical installation usually, sucks air from the side and comes the needed oxygen of fuel gas in the supplementary furnace, can not get exchange and be positioned at kitchen range chamber, blower fan top air, and temperature is high, influences the life-span of the components and parts of being installed in the kitchen range chamber; Do not have delivery port in the intake stack, when cleaning the kitchen range top, water is prone to flow into blower fan along ajutage, causes the electrical machine insulation performance of blower fan to reduce, and makes the damage of motor, even produces the electric leakage accident.
Summary of the invention
The utility model purpose is to overcome the shortcoming that existing food and drink cooking stove blower fan exists, and provides a kind of and can control rotation speed of fan automatically, the intelligent power saving kitchen range of energy-efficient automatic control blower fan.
The technical scheme that the utility model adopted is a kind of intelligent power saving kitchen range that can control rotation speed of fan automatically; It comprises combustion chamber, the kitchen range top, blower fan; Its structural feature is that the control system of blower fan is made up of single-chip microcomputer, blower fan sensor, flame detection sensor; Flame detection sensor is a thermocouple, and flame detection sensor is contained in the fan outlet place in the combustion chamber, and power switch, startup button, driving switch, blower fan sensor, flame detection sensor, blower fan link to each other with single-chip microcomputer.
Has processing center, comparator, isochronous controller, 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 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.
The utility model is on the basis of existing cooking stove, to introduce single-chip microcomputer as control centre blower fan 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.The initial single-chip microcomputer of starting shooting detects the blower fan sensor, in case occur unusually, single-chip microcomputer will stop complete machine work, to try to avert accidents.
Flame detection sensor and igniter angulation are 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; Detect the combustion chamber temperature through flame detection sensor, single-chip microcomputer is controlled the wind speed of blower fan according to temperature, and when firepower was big, temperature was high, and current potential is big, and rotation speed of fan is fast; When firepower hour, temperature is low, and 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, sets through single-chip microcomputer and works as current potential less than definite value, and the blower fan full speed running is so that dispel the fuel gas that does not have burning in the burner.
The air-vent of blower fan makes progress, and the surfaces of revolution of fan blade is parallel to the ground.On the air-vent of blower fan, be connected to the air inducing dish, fan outlet straight tube below is equipped with drain valve.
And the utility model blower fan adopts horizontal installation, air-vent upwards, air intake has absorbed around the air-vent about 80% heat, reduces environment temperature in the kitchen range on the one hand, prolongs components and parts service life; Make air intake be able to heating on the other hand, deliver to burner by ajutage, take heat to burner, improve the calorific value in the stove, energy savings through the fan blade of blower fan; And below the fan outlet straight tube, drain valve is installed, in the time of can preventing to clean the kitchen range top, water flows into blower fan along ajutage, causes damage.
The advantage of the utility model is; Introduce single-chip microcomputer and blower fan is handed over its control as control centre; Make blower fan by manually becoming Single-chip Controlling; Can make it to change automatically through programming with the air valve driving switch, make combustion process air-fuel ratio blend range rationally, sufficient combustion, energy-conservation, reduce pernicious gas discharge capacity such as CO.Blower fan adopts horizontal installation, and air-vent makes progress, and air intake absorbs the outside heat of burner hearth, thereby reduces environment temperature in the kitchen range.
