Description

Decoct the control circuit of oil cauldron

Technical field

It the utility model is related to natural gas cooker technical field, and in particular to a kind of control circuit of pan-fried oil cauldron.

Background technology

In existing equipment, it is as follows to decoct the process of oil cauldron igniting, manually lights the naked light of burner first, starting ignition button, Steam supply valve is opened air blower simultaneously and run, and the combustion gas in burner is ignited, and pan-fried oil cauldron starts to warm up, while in the mistake of production and processing Need personnel to monitor the fired state of combustion gas always in journey, need operating personnel to close steam supply valve immediately when combustion gas is extinguished, but Be if not closing steam supply valve in time when combustion gas is extinguished in stove, will in assembly stove combustion gas it is excessive, when so lighting a fire again Detonation just occurs, great potential safety hazard be present.

Utility model content

When the utility model overcomes combustion gas extinguishing in pan-fried oil cauldron burner in the prior art, operating personnel do not close in time During steam supply valve, the deficiency that deflagration phenomenon occurs in igniting again be present, there is provided it is a kind of when combustion gas is extinguished in pan-fried oil cauldron burner, can To close steam supply valve in time, avoid decocting the control circuit of oil cauldron caused by deflagration phenomenon.

To achieve the above object, the utility model uses following technical scheme：

A kind of control circuit of pan-fried oil cauldron, it includes combustion controller, the first pin and the main combustion of the combustion controller Air valve electrically connects and accesses zero line N, and the second pin of the combustion controller electrically connects with ignition transformer and ignition electrode successively, 3rd pin of the combustion controller electrically connects with the air valve that ignites and accesses zero line N, the 4th pin of the combustion controller Electrically connected with live wire L, the 5th pin of the combustion controller electrically connects with zero line N, the 6th pin of the combustion controller Electrically connected with live wire L, the 7th pin of the combustion controller electrically connects with ignition switch and accesses live wire L, the burning control 8th pin of device processed electrically connects with shutdown switch and temperature controller and accesses live wire L respectively, the live wire detector difference Electrically connected with the 9th pin of combustion controller and the tenth pin.

Compared with prior art, the beneficial effects of the utility model are：

The utility model decocts the control circuit of oil cauldron by providing, and being realized by control circuit can when combustion gas is extinguished in stove To close main gas valve in time, during so as to avoid lighting a fire again, the generation of deflagration phenomenon.

Brief description of the drawings

Fig. 1 is a kind of circuit theory diagrams of the control circuit of the pan-fried oil cauldron of embodiment of the present utility model.

As shown in figure 1, wherein corresponding reference is entitled：

101 flame detectors, 102 temperature controllers, 103 shutdown switches, 104 ignition switches, 105 combustion controllers, 106 Main gas valve, 107 ignition transformers, 108 ignition electrodes, 109 ignite air valve.

Embodiment

The utility model is further elaborated below in conjunction with the accompanying drawings.

As shown in figure 1, a kind of control circuit of pan-fried oil cauldron, it includes combustion controller 105, the combustion controller 105 The first pin electrically connected with main gas valve 106 and access zero line N, the second pin of the combustion controller 105 successively with point Fiery transformer 107 and ignition electrode 108 electrically connect, and the 3rd pin of the combustion controller 105 electrically connects simultaneously with the air valve 109 that ignites Zero line N is accessed, the 4th pin of the combustion controller 105 electrically connects with live wire L, and the 5th of the combustion controller 105 draws Pin electrically connects with zero line N, and the 6th pin of the combustion controller 105 electrically connects with live wire L, the combustion controller 105 7th pin electrically connects with ignition switch 104 and accesses live wire L, the 8th pin of the combustion controller 105 respectively with stopping Switch 103 and temperature controller 102 electrically connect and access live wire L, the live wire detector 101 respectively with combustion controller 105 The 9th pin and the tenth pin electrical connection.

The model BC1000 for preferably producing combustion controller selection for Honeywell Int Inc in the present embodiment Combustion controller.

Operation principle of the present utility model is as follows：

Ignition switch 104 is pressed first, and combustion controller 105 controls the air valve 109 that ignites to open, while ignition transformer 107 work sparkings are ignited combustion gas, and when flame detector 101 detects that the conduit that ignites has ultraviolet, combustion controller 105 is controlled Make main gas valve 106 and air blower while work, put combusting range, decoct oil cauldron normal work, when temperature controller 102 detect it is pan-fried (shutdown switch 103 can be pressed) when vegetable oil in oil cauldron reaches design temperature, the normally-closed contact of temperature controller 102, which disconnects, to be cut Break main gas valve 106 and blower power supply, and main gas valve 106 and air blower stop, and turn off the air valve 109 that ignites；

When burner in the course of the work, if flame detector is not detected when the conduit that ignites does not have a ultraviolet (i.e. Combustion gas is extinguished), combustion controller 105 immediately simultaneously closes off main gas valve 106 and air blower, will not thus pass through main combustion gas Valve 106 by more than combustion gas introduce in stove, would not have the combustion gas of residual in stove, just can effectively avoid the hair of deflagration phenomenon It is raw；When flame detector 101 does not detect that 10 seconds after-burning burning controllers 105 of ultraviolet trigger ignition transformer in stove The air valve 109 that ignites is opened simultaneously for 107 sparkings, lights the combustion gas of air valve 109 of igniting；Flame detector 101 has detected ultraviolet, Combustion controller 105 opens main gas valve 106 and air blower, burner normal work.

Essence of the present utility model is described in detail above embodiment, but can not be to of the present utility model Protection domain is limited, it should be apparent that, under enlightenment of the present utility model, those of ordinary skill in the art can be with Carry out many improvement and modification, it should be noted that these are improved and modification all falls in claim of the present utility model protection Within the scope of.
