Description

Household natural soot exhauster

The utility model relates to the man kitchen of a kind of eliminating soot device, particularly gets rid of tame kitchen soot device naturally.

The flue gas that uses the gas-cooker burning to produce is diffused into the kitchen, will reduce indoor oxygen content as untimely eliminating, causes imperfect combustion, reduces the thermal efficiency, and contain CO, CO in the flue gas of imperfect combustion generation ₂, H ₂S, SO ₂, NO, NO ₂, CH ₄, C _mH _nDeng pernicious gas, make human body be subjected to serious infringement, coal gas fume pollution indoor environment becomes grease to be difficult to clean at kitchen tools with the kitchen surface area.General solution is ventilating fan is installed or in the top position of gas-cooker smoke exhaust is installed and is adopted flue gas in the force ventilated mode dilution chamber at the kitchen window, this method has just reduced the pernicious gas in the kitchen, oil smoke still fires seriously the pollution in kitchen, and use 60～120W motor, noise is arranged, cost is higher, service life is shorter.

The purpose of this utility model provides a kind of tame kitchen soot device of getting rid of naturally, and it can be got rid of the oil smoke of gas-cooker burning generation up hill and dale and get rid of flue gas and the steam that the cooking produces simultaneously, and is simple in structure, makes combustion gas completing combustion.

To achieve these goals, the utility model is taked following proposal: the utility model comprises windguard, hood, fume pipe, windguard is fixed on hood top, and the lower inside of windguard has oil trap, and the upper orifice of fume pipe extends and is higher than the windguard lower limb in the windguard; A back taper air blocking cap is installed in upper orifice top position at fume pipe; Be connected with the flue gas arm and form threeway at the fume pipe lower nozzle, in threeway, vertically fix a dividing plate with the partial fume arm; Each fixes one pot smoke-accumulating ring two mouths of pipe of flue gas arm, propping up a pot smoke-accumulating ring is the tubular enclosure of subtriangular or rectangle, form annular cavity in the pipe,, stopping table is arranged in a bottom of pot smoke-accumulating ring at a smoke hole that the inside circumference of pot smoke-accumulating ring distributes and communicates with inner chamber.Prop up inner chamber the flue gas arm and the fume pipe UNICOM of pot smoke-accumulating ring, on a pot smoke-accumulating ring, the individual fiery device of peeping is arranged, peep fiery device and link corresponding position, place promptly near the valve body position of the switch of gas-cooker, peep fiery device and peep fire hole or peep fiery groove at a pot smoke-accumulating ring and flue gas arm.Peeping fiery device for two kinds all separates with the inner chamber of metal with hole or a groove and a pot smoke-accumulating ring, pot smoke-accumulating ring replaces on the kitchen range face that pan bracket places gas-cooker and with stopping table and places in the kitchen range hole, stopping table can prevent to prop up a pot smoke-accumulating ring and slide along the kitchen range face, observes the flame of burner by propping up the fiery device of peeping of pot smoke-accumulating ring behind the some cooking stove burning.A pot smoke-accumulating ring can support pot and prevent that with the bottom of a pan combustion product gases expansion that leaks from teaching the kitchen, the flue gas of burning can only enter an inner chamber of pot smoke-accumulating ring by an exhaust hole of pot smoke-accumulating ring, enter fume pipe through the flue gas arm then, flue gas rises to windguard naturally, flue gas or steam major part except that small part is diffused into the kitchen that the cooking produces rise to hood, the getter plate at the hood both sides and the back side increases the getter function of hood, flue gas or steam that the cooking produces rise to windguard, and the flue gas that produces with burning is discharged outdoor by chimney by the kitchen window or discharged by flue.Few partial combustion oil smoke and cooking flue gas or steam rise get rid of run into windguard side plate particularly the chimney wall be condensed into liquid along chimney and windguard plate current to oil trap, be inverted vertebra shape air blocking cap and prevent that downdraught from entering fume pipe, and can limit exhaust smoke level and prevent to influence combustion efficiency.

Lay two pot rings that diameter is different at a pot smoke-accumulating ring, the external diameter of big pot ring adapts with a top mouth diameter of pot smoke-accumulating ring, so that will prop up pot ring is placed on the pot smoke-accumulating ring and with the oil smoke sealing of the bottom of a pan with the burner top, the external diameter of ramuscule pot ring is slightly larger than the internal diameter of big pot ring, be convenient to its peace side on big pot ring, have the step of high about 2mm to be convenient to locate at the outer ledge of large and small pot ring.There has been a pot ring can adapt to pan, the tip bottom pot of all sizes such as milk pot and 22,24,26,28cm of 16cm, also can have regulated the fire height.

In order to adapt to the gas-cooker of different size, flue gas arm of the present utility model can adopt the telescopic retractable structure, with the lower end horizontal fixed one straight tube formation threeway of fume pipe, will inject straight tube with an other end mouth of pipe of the bend pipe that the pot smoke-accumulating ring is fixing.Just can regulate the distance of two pot smoke-accumulating rings.

Can fix a conduit at the oil trap of windguard, the lower end of conduit puts in fume pipe from the side, and the oil of oil trap and condensed water flow to fume pipe chance hot gasization from conduit and discharge by fume pipe and windguard.

Because the utility model adopts the mode of a pot smoke-accumulating ring (with the bottom of a pan) with the smoke evacuation of burner top sealing fume pipe, just the oil smoke that can prevent from up hill and dale to burn is diffused into the kitchen and flue gas is discharged outdoor, avoided combustion gas grease and pernicious gas to indoor pollution, and be used simultaneously with windguard and hood and get rid of steam and the flue gas that the cooking produces, the utility model makes combustion gas completing combustion, owing to adopt the cavity tubular type with smoke hole to prop up the uniformity that pot smoke-accumulating ring has kept flame.The utility model utilizes natural draught system, not consumed power, method for maintaining, and is not fragile.

Concrete structure of the present utility model is provided by embodiment and accompanying drawing thereof.
