Cooker with protection function

Abstract

The invention discloses a stove with a protection function. A liquid discharge tube and a return mechanism are set up, an aeration fan starts to work, when air pressure meets a set value, the return mechanism is driven by the air pressure to seal a liquid discharge hole, and new oxygen is fed into a combustor to join in combustion reactions; when the air pressure is lower than the set value, the return mechanism is returned, the liquid discharge hole is opened, and then the liquid is prevented from flowing back to damage the aeration fan or shorten the service life of the aeration fan; an airpressure detection tube linked with a gas switch is arranged on an air supply pipeline, gas supply can be cut off in time if the air pressure is lower than the set value, and the danger that fire hazards are caused by back combustion is avoided; an air blowing tube is arranged on the air supply pipeline, cleaning and cooling functions on a circuit control device are achieved through cold air blownout from the aeration fan, and the service life of the circuit control device is prolonged.

Description

technical field [0001] The invention relates to the technical field of energy-saving cookers, in particular to a cooker with protection function. Background technique [0002] Nowadays, many energy-saving cookers, especially semi-premixed commercial energy-saving cookers, when the blower pipeline pressure drops to a certain value, the premixed gas will be backfired and burnt, causing a fire in severe cases. [0003] In addition, during the use of the cooking range, liquid is often poured into it, and these liquids flow into the oxygenation fan along the outlet pipe of the oxygenation fan, causing damage to the oxygenation fan. [0004] Third, most of the current energy-saving cooking appliances are equipped with electrical appliances such as control circuits, ignition circuits, and solenoid valves. Contents of the invention [0005] In view of this, the present invention proposes a cooker with protection function that can effectively prevent liquid from pouring back and s...

Problems solved by technology

[0002] Now many energy-saving cookers, especially semi-premixed commercial energy-saving cookers, when the blower pipe pressure drops to a certain value, the premixed gas will be backfired and burnt, causing a fire in severe cases

[0003] In addition, during the use of the stove, liquid is often poured into it, and the liquid flows into the oxygenation fan along the outlet pipe of the oxygenation fan, causing damage to the oxygenation fan

[0004] Third, the current energy-saving cooker appliances are mostly equipped with electrical appliances such as control circuits, ignition circuits, and solenoid valves. The environment of the stove is relatively harsh: high temperature, humidity, and excessive oily smoke, which are prone to failure or shortened service life.
