Abstract
The invention belongs to burning equipment and in particular belongs to energy-saving cooking stoves with flame detection sensors. The invention discloses an energy-saving cooking stove with a flame detection sensor. The energy-saving cooking stove comprises a furnace core, a cooking stove and a fan. The technical key points of the invention are as follows: the energy-saving cooking stove comprises a single chip microcomputer and the flame detection sensor, wherein the single chip microcomputer, as a controlling center, is connected with the flame detection sensor and the fan. According to the energy-saving cooking stove disclosed by the invention, the single chip microcomputer is introduced as the controlling center on the basis of the traditional cooking range and used for controlling the fan and the like, so that the fan is controlled by the single chip microcomputer by replacing manual operation; the flame detection sensor is used for detecting temperature in the furnace core and further controlling the rotational speed of the fan, and thus in the burning process, an air-fuel ratio mixing range is reasonable, burning is full, energy is saved, and discharge capacities of harmful gases, including CO, are reduced.
Description
Technical field
The invention belongs to combustion apparatus, especially belong to the energy-saving stove with flame detection sensor.
Background technology
The size of its combustion gas of cooking stove that catering trade uses is controlled by main air valve; the size of air inlet amount is by air-blower control; not interlock between the two; switch is not also at a place; by manually selecting respectively the two; usually there will be main air valve open degree to have changed, blower fan is not and then variation but, and the two does not mate and causes combustion gas usefulness to reduce.
Summary of the invention
The object of the invention is to overcome the shortcoming that existing food and drink cooking stove exists, provide a kind of can temperature in perception combustion chamber, and with this temperature for according to the energy-saving stove with flame detection sensor carrying out blower fan automatically controlling.
The technical solution adopted in the present invention is a kind of energy-saving stove with 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 flame detection sensor and blower fan as control centre.
The present invention introduces single-chip microcomputer to hand over it to control blower fan etc. as control centre on the basis of existing cooking stove, make blower fan from manually becoming Single-chip Controlling, the temperature in combustion chamber is detected by flame detection sensor, and then control rotation speed of fan, make combustion process air-fuel ratio blend range rationally, sufficient combustion, energy-conservation, reduce the pernicious gas discharge capacities such as CO.
Flame detection sensor is thermocouple, and it and igniter are all contained in combustion chamber, and the two angulation is 90--270 degree, and flame detection sensor is contained in the air outlet position of blower fan.
Utilize thermocouple to make flame detection sensor, when after flame combustion, create potential difference at its two ends after thermocouple is heated, flame is larger, the temperature of fire prospecting needle is higher, and the potential difference of generation is larger, on the contrary, flame is less, and the temperature of fire prospecting needle is lower, and the potential difference of generation is less; Single-chip microcomputer by with the comparator of flame detection sensor phase spare and accessory parts in set potential value and judge, according to flame size, control rotation speed of fan, when firepower is large, current potential is large, and rotation speed of fan is large; When firepower hour, current potential is little, and rotation speed of fan is slow; After flame-out, thermocouple heat radiation is accelerated in the air outlet good heat radiating position of blower fan, so that electrical potential information when CPU reads flame-out more rapidly.Time flame-out, current potential is minimum, by setting when current potential is less than definite value, blower fan full speed running, to dispel the fuel gas not having in burner to burn.
The present invention introduces single-chip microcomputer to hand over it to control blower fan etc. as control centre on the basis of existing cooking stove, make blower fan from manually becoming Single-chip Controlling, the temperature in combustion chamber is detected by flame detection sensor, and then control rotation speed of fan, make combustion process air-fuel ratio blend range rationally, sufficient combustion, energy-conservation, reduce the pernicious gas discharge capacities such as CO.

Detailed description of the invention
Be described in detail the present invention below in conjunction with view, the following examples can make professional and technical personnel more understand the present invention, but do not limit the present invention in any form.
Embodiment 1, as shown in Figure 1, Figure 2, a kind of energy-saving stove with flame detection sensor, it comprises combustion chamber 1, the kitchen range top 2, blower fan 4, in existing cooking stove, add single-chip microcomputer 5 and flame detection sensor 21, single-chip microcomputer 5 is connected with flame detection sensor 21 and blower fan 4 as control centre.
Flame detection sensor 21 is thermocouple, and it and igniter 6 are all contained in combustion chamber 1, and flame detection sensor 21 is contained in air outlet 44 position of blower fan, the two angulation is 90--270 degree, be preferably 180 degree, when preventing high-tension ignition, high-tension electricity seals in sensor, damages sensor.
The course of work of the present invention is after power switch is opened, single-chip microcomputer is to blower fan 4, flame detection sensor 21 detects, after all are in normal condition, single-chip microcomputer 5 is in order: power switch 11--starts button 12--driving switch 13, accept the instruction of operating key successively, after igniting, temperature in combustion chamber is passed to single-chip microcomputer 5 by flame detection sensor 21, single-chip microcomputer adjustment rotation speed of fan, 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 according to flame detection sensor detect temperature in combustion chamber, by regulating the blower voltage angle of flow, ± the fine setting of 10% is had to the rotating speed of every grade of blower fan, extinguish when flame is abnormal, flame detection sensor temperature drops to setting value, the processing center of single-chip microcomputer closes all air valves, in case gas leakage, blower fan works on and dispels unburned combustion gas in 30 seconds.
