Abstract
The present invention relates to a kitchen apparatus, particularly to a combined thermal insulation silencer in fume ducts of cooking fume removers. An outer layer of the combined thermal insulation silencer is a porous thermal insulation silencing layer of which the material is rock wool, and a silencer with a double-layer silencing panel with cavity gaps is arranged in the outer layer. The present invention has the advantages that oil drops in oil fume in a fume duct are separated by the silencer with a double-layer silencing panel with cavity gaps in the middle, and the oil drops can not permeate into the porous rock wool layer of the outer layer so as to eliminate the unsafety that the porous rock wool layer can catch fire owing to the porous rock wool layer saturated with the oil drops and restore the original thermal insulation silencing effect of the porous rock wool; meanwhile, on the aspect of silencing, owing to the additional superposed silencing effect of the silencer with a double-layer silencing panel with cavity gaps, the present invention is excellent in silencing performance.
Description
(1) technical field:
The present invention relates to cooking apparatus.
(2) background technology:
The inventor has applied for one " detachable cabinet type smoke exhaust ventilator " on August 1st, 2000 to Patent Office of the People's Republic of China, application number is 00245649.4, discloses a kind of heat insulation silencing apparatus as smoke exhaust ventilator such as one deck porous heat-insulating deadener such as rock wool that installs additional in the smoke exhaust ventilator flue.Its purpose one is that the protection flue both sides condiments of draining the oil in the salt sauce vinegar bottle kitchen cabinet is unlikely roasting as to cross thermal metamorphism by oil smoke, the 2nd, play further noise elimination effect.But through industrial experimentation repeatedly, find that its effect is undesirable, reason is this porous heat-insulating deadener layer such as rock wool etc., and its surface directly contacts with oil smoke, and the time has been grown, and the oil droplet in the oil smoke can slowly be penetrated in the porous heat-insulating deadener rock wool layer and go.Make the porous material rock wool layer become a rock wool layer that is full of oil-containing, not only lost the characteristic of heat insulation noise elimination, also existing causes the insecurity that oil droplet catches fire.
(3) summary of the invention:
Technical problem to be solved by this invention is how to prevent from technically that oil droplet in the oil smoke is penetrated in the porous heat-insulating silencing plate in the flue to go, with the heat insulation acoustic attenuation performance of raising porous heat-insulating silencing plate, and prevent that the porous heat-insulating silencing plate is because of containing the insecurity that oil droplet catches fire.
Technical problem to be solved by this invention is achieved in that the heat insulation silencing apparatus in a kind of smoke exhaust ventilator flue, comprise the porous heat-insulating silencing plate, it is characterized in that: it has formed a heat insulation silencing apparatus of combined type by being positioned at the outermost porous heat-insulating silencing plate of flue jointly with the silencer of the double-deck muffler plate of the band lacuna of being close to this porous heat-insulating silencing plate nexine, the internal layer muffler plate of lacuna is the muffler plate of a band micropore, it directly contacts with the flue oil smoke, the outer muffler plate of lacuna is a muffler plate of not boring a hole with micropore, and the outside of muffler plate then is described outer porous heat-insulating silencing plate outside.
The material of described porous heat-insulating silencing plate is rock wool or glass silk flosssilk wadding.
Described porous heat-insulating silencing plate is by being with the chemical fabric veneer of one deck aluminium foil veneer or heat-resisting antiseep on the inside and the one side that oil smoke contact.Purpose is to block oil droplet and is penetrated in the porous heat-insulating silencing plate and goes.
Described chemical fabric veneer is a heat-resisting chemical fabric veneer of being handled by process antiseep coating.
Described aluminium foil veneer or chemical fabric veneer available polyethylene glue or fire retardant glue are bonded on rock wool or the glass silk flosssilk wadding.
The advantage that the present invention is compared with prior art had:
1) advantage of the porous heat-insulating silencing plate of the chemical fabric veneer of band aluminium foil veneer or antiseep is: aluminium foil veneer or chemical fabric veneer have been blocked oil droplet and have been penetrated in the porous heat-insulating silencing plate and go, recovered the original heat insulation acoustic attenuation performance of porous heat-insulating silencing plate rock wool or glass silk flosssilk wadding, side by side except the porous heat-insulating silencing plate because of being full of the insecurity that oil droplet catches fire.
2) advantage of the heat insulation silencing apparatus of combined type is: oil droplet has been kept apart by the outer imperforate dull and stereotyped blocking-up of lacuna in the oil smoke, gone in the porous heat-insulating silencing plate of oil leakage infiltration less than ragged edge, both eliminated the porous heat-insulating silencing plate because of being full of the insecurity that oil droplet catches fire, recovered the original heat insulation noise elimination effect of porous heat-insulating silencing plate such as rock wool or glass silk flosssilk wadding again, simultaneously aspect noise elimination, because also added the noise elimination effect of the double-deck muffler plate silencer stack of band lacuna, therefore, has more excellent acoustic characteristics.
(4) description of drawings:
Fig. 1, Fig. 2 are the heat insulation silencing apparatus figure of the combined type in the separating kitchen ventilator flue, and Fig. 1 is the A-A cutaway view of Fig. 2.
(5) specific embodiment
Fig. 1 Fig. 2 is the heat insulation silencing means embodiment in the separating kitchen ventilator flue, wherein: the Connection Block 1 of external smoke extracting tube, both sides kitchen cabinet 2, porous heat-insulating silencing plate 3 (material is rock wool or glass silk flosssilk wadding), the outer muffler plate 4 of lacuna, it is a muffler plate of not boring a hole with micropore, the control crack 5 of silencer, be positioned at the centre of ectonexine muffler plate, the internal layer muffler plate 6 of lacuna, be the muffler plate of band micropore perforation, the flue 7 in the smoke extractor, smoking port 8, the oil collection box 9 of smoke exhaust ventilator bottom, the dodge gate 10 of both sides kitchen cabinet 2, the heat insulation silencing apparatus of this combined type by the porous heat-insulating silencing plate 3 of outside and the inside by lacuna 5, the common heat insulation silencing apparatus of forming a combined type of muffler that outer muffler plate 4 of lacuna and lacuna internal layer muffler plate 6 are formed, wherein the width of lacuna 5 is the 10-50 millimeter; The internal layer muffler plate 6 of the band micropore perforation of lacuna 5, the diameter of its micropore perforation is the 0.6-1.0 millimeter, punching rate is 1%-3%; The internal layer muffler plate 6 of lacuna 5 and the thickness of slab of outer muffler plate 4 are the 0.7-1.0 millimeter.
One deck aluminium foil veneer is arranged on porous heat-insulating silencing plate 3 inner surfaces, and it is between the outer muffler plate 4 of porous heat-insulating silencing plate 3 and lacuna, and the porous heat-insulating silencing plate that the oil droplet that the effect of this aluminium foil veneer is to block 7 li oil smoke of flue is penetrated into the outside goes for 3 li.
