Gas steaming oven

The invention discloses a gas steaming oven, and relates to the technical field of steaming oven equipment. The gas steaming oven comprises an oven body, wherein the oven body comprises a steam chamber and a water tank chamber, wherein a gas heating system is arranged outside the water tank chamber; the gas heating system comprises a gas delivery pipeline; the gas delivery pipeline is communicatedwith a gas-controlled combustion device and an ignition detecting device; the gas-controlled combustion device comprises a combustion head and a first valve for controlling the switching on and off of the combustion head; the ignition detecting device comprises an ignition head and a second valve for controlling the switching on and off of the ignition head; a flame probe is linked with the ignition head; the gas delivery pipeline is communicated with a third valve linked with the flame probe; the flame probe controls the switching on and off of the third valve; the first valve and the thirdvalve are connected in series, and the second valve and the third valve are connected in parallel. Ignition and combustion actions are completed through the matching of the ignition detecting device and the gas-controlled combustion device, and explosion risks caused by gas leakage of the pipeline, gas leakage of the combustion head or gas leakage of the ignition head can be reduced through the matching of the ignition detecting device and the gas-controlled combustion device, so that the purpose of increasing the using safety of the gas steaming oven can be achieved.
