Description

Kitchen automatic smoke discharging device

One, technical field

The utility model belongs to a kind of kitchen natural draught system device, is a kind of kitchen automatic smoke discharging device specifically.

Two, background technology

People had used chimney (vertical gas pass) smoke evacuation in the past, but just were used to discharge the flue dust that produces when cooking stove burns coal or burns bavin, and the oil smoke that produces on the kitchen range top during culinary art operation is still polluting environment within doors.Immediate prior art " range hood " because the area of the volume of its smoke collecting chamber and exhaust opening is too little, exists following defective and deficiency though can get rid of oil smoke in the smoke evacuation process: 1, lifelong consume electric power, and smoke evacuation produces economic drain; 2, produce dry sound interference environment, the communication that influence is outer within doors; 3, the operation sequence of startup and shutdown and forget start or the shutdown pollution or the waste that cause is arranged; When 4, producing a large amount of oil smoke suddenly rapidly and rise (during or on the kitchen range several pots reach fluidized state simultaneously) as firm proclamation lid, the oil smoke that its smoke collecting chamber cannot not hold intactly, that is to say the oil smoke of not getting into smoke collecting chamber, at once do not have condition to discharge and contaminated environment still in the roof with regard to being raised to; 5, discharge outside window oil smoke have by wind again blowback advance own other problem that pollutes within doors; 6, the smoke evacuation function of most range hood is too poor, must shut backstairs during smoke evacuation, causes the staff can't breathe the problem of fresh air for this reason; 7, frequent (general annual) consumption money of existence and trouble of asking the professional take parts cleaning grease to the doorstep apart consuming time.

Three, utility model content

This novel purpose is to provide smoke evacuation not need to add a kind of kitchen automatic smoke discharging device that electric energy and electrical equipment carry out at the above problem and shortage of prior art, and its exhaust smoke level is bigger, it is more convenient to use.This novel purpose is realized by following design: a kind of kitchen automatic smoke discharging device, comprise smoking channle common duct and only family flue that connects smoke collecting chamber, also comprise every layer within doors the common duct smoking channle place of top-side rectangle be set be this layer smoking channle import within doors for horizontal mouthful, also be the smoke collecting chamber outlet; Solely flue smoking channle bottom in family connects an elbow, and the open wells bigger slightly than floss hole area of elbow tail end is only family chimney intake, and solely the family chimney intake is installed in the top-side outlet of smoke collecting chamber; The outer installation of outlet flue of the family common duct attic and only flue can be enclosed to keeping out the wind of the lower end of upper end and flue outlet periphery smoke evacuation; Keep out the wind and cross mouth upper end installation rain visor; Oil guiding net and oil storage tank are installed in the smoke collecting chamber.From above-mentioned design as seen, smoke collecting chamber is with after vertical smoking channle is communicated with, strengthened the attraction of smoke collecting chamber and smoking channle, strengthened the accommodation function of smoke collecting chamber again, heat energy and oil smoke produce the power of the principle of leaning on the rising of hot-air meeting nature in the back upwards in pouring smoke collecting chamber from the kitchen range top, heat energy is protected by smoke collecting chamber and is being controlled the power that can not laterally scatter and disappear and protect continuation to rise, and rushes at outside the outlet smoothly by vertical smoking channle; Keep out the wind and enclose the outlet that the pressure that prevents strong wind is pushed down outside smoke evacuation; Rain visor prevents that rainwater from entering in flue; Oil guiding net is derived the greasy dirt to airborne release; Oil storage tank fills can take off behind the oil and pours out; The attraction of the smoke collecting chamber of speciality has prevented that the oil smoke of lower floor's flue from scurrying into the problem in the kitchen, upper strata.Whenever therefore, no matter have oil smoke to produce on the kitchen range top, whenever it can both upwards discharge (smoke evacuation of business restaurant needs to increase pipeline area and height) completely automatically.

Compared with prior art, this is novel following characteristics and advantage: 1, the volume of smoke collecting chamber is roomy, the degree of depth is sufficient, discharge area is big, can exhaust a large amount of oil smoke that produce rapidly suddenly on the kitchen range top, oil smoke can lead to smoking channle from smoke collecting chamber smoothly, oil smoke is from the process that smoke collecting chamber passes through, oil smoke seldom puts off till the inwall around the smoke collecting chamber, the protection of nature the cleaning of smoke collecting chamber; 2, the greasy dirt of hiding nowhere in the smoke collecting chamber; 3, simple in structure, easily manufactured, material source is wide; 4, smoke evacuation does not need to add electric energy and electrical equipment, has solved smoke evacuation and has produced the economic drain problem; 5, solve dry sound and disturbed, influenced the inside and outside communication problem in kitchen; 6, the smoke evacuation function of having a rest is arranged never, solved the trouble of startup and shutdown in the smoke evacuation every day process and forgotten start or shutdown pollutes or the waste problem; 7, solve oil smoke and run the problem that to discharge in the roof that goes up; 8, solved the oil smoke of discharging can by wind again blowback advance other problem that pollutes within doors of oneself; 9, solved close just be beneficial to the doorstep discharge oil smoke and operating personnel's breathing not the problem of fresh air; 10, solved and often to consume money and the professional of asking consuming time and tear the problem that machine cleans grease open; This novel common duct type has solved others' environmental problem of fume pollution of discharging.This novel product that caused uses and observes confirmation through for a long time, above technical know-how is in full accord with actual situation about using, and family kitchen is with this new technique mist extractor, can reach save worry, relieved, satisfactory purpose.
