Description

Totally enclosed type kitchen smoke exhaust ventilator

The invention belongs to exhaustor for kitchen.

As everyone knows, when cooking food, can produce the oil smoke that is harmful to health, simultaneously this kitchen fume also can disperse indoor, hinder indoor cleaning.The exhaustor for kitchen of the various models in existing various countries still fails to stop ideally kitchen fume to the invasion and attack of cooker and to indoor wall floor splashing down and fly away contamination everywhere.According to the relevent statistics, kitchen fume is to cause one of maximum cause of death of human dead top ten.

Purpose of the present invention is just in order to reach the basic invasion and attack of kitchen fume to human body of thoroughly eliminating.Reach technical scheme of the present invention, as follows: (in conjunction with the drawing explanation)

Technical scheme of the present invention is fully closed smoke exhaust ventilator, even make the personnel of cooking foods such as cook, housewife also can not be subjected to the invasion and attack and the harm of kitchen fume in operation cooking (fry in shallow oil and fry boiling) process.

In structure of the present invention, following several basic part is arranged: one, sucktion fan; Two, the pipeline of past outdoor oil extraction flue gas; Three, the radome of cooking stove; Four, air inlet; Five, the air bag oversleeve of the arm of cooking food time envelope in moving up and down; The body feed tank that six, the double closing door that replaces is arranged; Seven, observation window; Eight, door; Nine, the lid of the slice bowl in door and cooking stove radome shelf.

Above-mentioned " one " and " two " are set, make kitchen fume to resemble to produce the conventional smoke exhaust ventilator to the suction force of oil smoke with toward the passage of outdoor discharge.So so inventive point of the present invention or unique distinction are being gone along with sb. to guard him cooking stove at the fully closed radome of adorning transparent air-locked fire proofing material formation on locus suitable around the cooking stove.Certainly need constantly there be fresh air to flow into during gas-fired, so establish the air inlet of louvre type at cooking stove two side lower parts, also have one to overlap the cover plate that venetian blind type independently can open with pull bar/close on this air inlet, when closed the air inlet inner air and outer air can not be circulated mutually.Even electric furnace, this air inlet also needs, so that the work of superincumbent sucktion fan the time allows the hot gas oil smoke after food is held in the pot upwards flow into outer smokejack, constantly has fresh air to flow into simultaneously, makes the oil smoke when cooking reverse flow not go into indoor.

Common cooking stove is two one rows (about each) or four, front and back two rows (about every row each one), and under most of occasions, people use that cooking stove on the left side to carry out cooking operation, also can use that cooking stove on the right side to carry out cooking operation simultaneously.Most of people hold the shovel shake operation with the right hand, especially the cooking food of Chinese style, people need be with holding shovel constantly brandishing the arm front and back mobile to some extent displacement in ground up and down, for this reason, the present invention has designed " oversleeve " of special-purpose special semi-pneumatic light (being enclosed within no ballast sense on the arm) integral gasbag bag, this gasbag is made the fire prevention veneer towards the side of cooking stove with the synthetic material of heat resistant fire-proof, be semi-pneumatic (filling then with lighter-than-air gas, for example helium etc. has noninflammability again) gasbag.Because be semi-pneumatic, so be not full harder gasbag.This semi-pneumatic soft gasbag can allow that arm random swing in certain amplitude range of people is brandished.This gasbag is radiation-like ground towards periphery by middle position (people's wrist part) and scatters the filament that some heat resistanceheat resistant fire prevention have certain elasticity or elasticity again, these filaments have certain outside tension force, it is a kind of outside away from the cooking stove focus that this gasbag is had, the tendency of the power that the direction of standing towards the operator bloats, simultaneously, operator's arm each when mobile, one servo-actuated slight power that makes the maintenance balance that resets than gasbag is automatically all arranged on all directions.This gasbag has certain thickness, that is to say, when the operator stretches into " sleeve hole " part of central authorities with hand, can respectively establish the door that just can allow import that hand, wrist stretch into and import department on the surfaces externally and internally of this gasbag, these inside and outside two valves can carry out opening and closing of push pull type with finger.After finishing cooking operation, these two door drawings can be closed, again the cover plate of two side-inlets is carried out the keying of push pull type simultaneously.After finishing culinary art, these two door drawings can be closed, again the cover plate of two side-inlets is closed simultaneously, so the inside and outside air of this cooking stove is just completely cut off.Because this radome is made with fire proofing material, so when use is of the present invention, can produces isolated coal gas and leak, prevent possible fire spread effect of combustion, add conventional warning device, make the house safer.

In cooking process, thus food or batching often be not disposable whole addings be provided with a body feed tank in the present invention.This body feed tank can be located within the whole radome, and it has the door that opens/close of two activities, and a door is external, opens and closes door from the outside by the operator, puts into or take out the food or the auxiliary material that are contained in the container, and another is internal, and it also is able to turn on or off.Stretch into the air bag oversleeve on the right side by the operator with hand, remove to open/close the internal door of body feed tank again.Oil smoke gas leaks when preventing to cook, and before the operator opened the internal door of body feed tank, the operator should close the external door of body feed tank earlier.

Use or place slice for the ease of the operator, the present invention leaves slightly in shielded box that the mode with pylon or shelf is provided with a shelf for placing slice or basin bowl pot cover on the locus of cooking stove, so that the operator needn't open the door of radome as far as possible in gastronomical process, just can be engaged in the cooking and relevant essential operation thereof.

The front of radome, it is a door of splitting, the door topmost be on the left side the door on body feed tank, be observation window under it, this window is made transparent minute surface with the material of not being stained with heat steaming steam, takes the form of inclined plane, so that the food that cooker is observed in the pot is being fried in shallow oil the situation of frying in the boiling, the inner surface of this window also can be adorned the device of automatic or manual similar " windshield wiper ", the window face steam that swings back and forth and block sight line to wipe.If the space around the cooking stove is narrower, the hinge of door can be made and can be inserted, on the door of the movable installation that extracts.

The Lower Half of the door on the left side can be bigger, thereby the soft gasbag of its underpart can be greatly, so that operator's wrist scope of activities is bigger, for example, he can stretch into the oversleeve tube and stretch to hingle or pot cover on the cooking stove on the right side with hand, is engaged in operations necessary.

Vessel on cooking stove (so pot, hingle, pot cover may correspondingly should be arranged on the appropriate location by bigger, high this radome, is reserved enough bulk for putting vessel and with hand operated (put into material, or hold the pot cover pot handle)

The operation knob of cooking stove (coal gas or electric switch) is just in time to be located under the radome, so the existence of radome does not hinder the normal use of these switches.If some kitchen space is too narrow, totally-enclosed cover of the present invention can be made movable, the time spent does not push certain distance with it to the rear portion of cooking stove, can take one section soft foldable structure for this reason or adorn the structure of an activity on totally-enclosed cover top, this structure can move a suitable short distance forward or backward around a fixing axle center.

Effect of the present invention is: in gastronomical process, the operator can optionally stretch into radome and air bag oversleeve with hand, and each carries out and finish operations necessary going on foot preface and action to swing simultaneously.In this process, the kitchen oil flue gas is isolated with the operator basically and is extracted out, is discharged to outdoor up hill and dale.Thus; make cooking person exempt from the invasion and attack of kitchen oil flue gas or the invasion and attack of accumulation property; operator and indoor household's health is protected; also making objects such as indoor wall, floor, furniture exempt from greasy dirt is infected with; keep indoor cleaning; since this time can prevent that when closing coal gas from leaking and fire spread, to the protection of building construction with avoid gas poisoning, immeasurable important meaning is arranged also.

Owing to close the negative pressure and the effect of air inlet air-flow upper punch of subenvironment in the sealing cover,, also do not have in the oil smoke effusion inlet chamber basically even in gastronomical process, open the door on the right once in a while.Body feed tank should be located at the top of the door on the left side, and its width is the diameter of a jorum approximately, the height when highly approximating a bowl and piling with material (free height in the body feed tank).
