Energy conservation stove with protection function

Abstract

The invention provides an energy conservation stove with a protection function. A liquid discharging pipe and a liquid discharging valve are arranged, when an oxygenation draught fan starts to work and the air pressure reaches a set value, the air pressure pushes a movable cover plate to rotate, a liquid discharging opening is closed, and newly-increased oxygen enters a burner to participate in reacting; when the air pressure is lower than the set value, the movable cover plate automatically rotates under the effect of the elastic force of a spring snap joint, the liquid discharging opening isopened, and the condition that liquid flows backwards, and consequently the oxygenation draught fan is damaged or the service life of the oxygenation draught fan is shortened is avoided; the liquid discharging pipe is provided with an air blowing pipe, cold air blown out from the oxygenation draught fan can be used for cleaning and cooling circuit control devices, and the service life of the circuit control devices is prolonged; and an air pressure detecting pipe linked with a fuel gas switch is arranged, and therefore when the air pressure is lower than the set value, fuel gas supply can becut off in time, and fire hazards caused by return fire burning are 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.
