Abstract
The utility model belongs to combustion equipment, and particularly belongs to an energy-saving stove with a flame detection sensor. The energy-saving stove with the flame detection sensor comprises a core, a cooking bench and a fan, and has the structural key point of being provided with a singlechip and the flame detection sensor, wherein the singlechip is used as a control center to be connected with the flame detection sensor and the fan. According to the energy-saving stove with the flame detection sensor, the singlechip is introduced to serve as the control center to control the fan and the like on the basis of the conventional cooking bench, so that manual control of the fan is change into control of the singlechip; and the temperature in the core is detected by the flame detection sensor to further control the rotation speed of the fan, so that the air-fuel ratio and mixing range is rational in a combustion process, the combustion is full, the energy is saved, and the emission of harmful gases such as CO is reduced.
Description
Technical field
The utility model belongs to combustion apparatus, especially belongs to the energy-saving stove that has flame detection sensor.
Background technology
The size of employed its combustion gas of cooking stove of catering trade is controlled by main air valve; The size of air inlet amount is controlled by blower fan, and the two is interlock not, and switch is not also at a place; By manual work the two is selected respectively; 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, provide a kind of can the perception combustion chamber in temperature, and serve as the energy-saving stove of controlling automatically according to blower fan that has flame detection sensor with this temperature.
The technical scheme that the utility model adopted is a kind of energy-saving stove that has flame detection sensor; It comprises combustion chamber, the kitchen range top, blower fan; Its structural feature is that it has single-chip microcomputer and flame detection sensor, and single-chip microcomputer is connected with blower fan with flame detection sensor as control centre.
The utility model is on the basis of existing cooking stove, to introduce single-chip microcomputer as control centre blower fan etc. 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.
Flame detection sensor is a thermocouple, and it and igniter all are contained in the combustion chamber, and the two angulation is the 90--270 degree, and flame detection sensor is contained in the air outlet position of blower fan.
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.
The utility model is on the basis of existing cooking stove, to introduce single-chip microcomputer as control centre blower fan etc. 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.
Description of drawings
Fig. 1 is the structural representation of the utility model
Fig. 2 is the control principle figure of the utility model
Wherein: 1 combustion chamber, 2 kitchens range top, 4 blower fans, 5 single-chip microcomputers, 6 igniters, 11 power switches 12 start button 13 driving switch 21 flame detection sensors 44 air outlets.
The specific embodiment
Below in conjunction with view the utility model is carried out detailed description, following embodiment can make the professional and technical personnel more understand the utility model, but does not limit the utility model in any form.
The course of work of the utility model is that single-chip microcomputer detected blower fan 4, flame detection sensor 21, after all are in normal condition after power switch was opened; Single-chip microcomputer 5 is in order: power switch 11--starts button 12--driving switch 13, accepts the instruction of operating key successively, after the igniting; Flame detection sensor 21 is passed to single-chip microcomputer 5 with the temperature in the combustion chamber, single-chip microcomputer adjustment rotation speed of fan, and the gear number of general blower fan is identical with the gear number of driving switch 13; Single-chip microcomputer carries out coarse adjustment according to driving switch to blower fan, and detects the temperature in the combustion chamber according to flame detection sensor, through regulating the blower voltage angle of flow; Rotating speed to every grade of blower fan has ± 10% fine setting; When flame extinguishes unusually, the flame detection sensor temperature drops to setting value, and the processing center of single-chip microcomputer is closed all air valves; In case gas leakage, blower fan works on and dispelled unburned combustion gas in 30 seconds.
