Energy-saving cooker with protection function

Abstract

The invention provides an energy-saving stove with a protection function. According to the stove, a liquid discharging pipe is arranged, so that when an oxygen increasing fan starts to work and the air pressure reaches a set value, the air pressure pushes a piston to move to seal a liquid discharging groove, and the newly-added oxygen enters a combustor through a ventilation groove to participatein the reaction; when the oxygen increasing fan stops working, the piston is returned under the action of the magnetic force of two magnets, and a liquid discharging opening is opened to allow a liquid entering the liquid discharging pipe to be discharged so that the liquid can be prevented from flowing backwards to damage the oxygen increasing fan or shorten the service life of the oxygen increasing fan; the piston automatically seals an air inlet under the action of the magnetic force of the two magnets in the non-working state of the oxygen increasing fan so that corrosive or polluted gas generated by combustion can be prevented from flowing back into the oxygen increasing fan, and the service life of the oxygen increasing fan can be prolonged; and an air pressure detection pipe linkedwith a fuel gas switch is arranged so that the gas supply can be cut off in time when the air pressure is lower than the set value, and fire disasters caused by backfire combustion can be prevented.

Description

technical field [0001] The invention relates to the technical field of energy-saving stoves, in particular to an energy-saving stove with a 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 an energy-saving cooker with a protection function that can effectively preven...

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.
