Description
The utility model relates to a kind of multi-functional hood, belongs to the kitchen auxiliary facility.
The family expenses air discharge hood for kitchen is multiple functional on China's city's field boundary at present, a great variety of models.The hood function singleness of the public kitchen in high-and middle-ranking hotel, stupid big stupid thick can not satisfy the needs that ventilate with sanitary condition by contrast.Conventional hood has only mist extractor and filters two kinds of functions of oil smoke, and the function that it has only air draft not replenish new wind, and unstable properties are subject to cross-flow invasion, and air quantity is wayward.Design air flow is little, and oil smoke overflows, and pollutes surrounding environment; , design air flow is big, forms negative pressure, causes the cooking stove drawing fires.Air-conditioned for air-conditioned kitchen or the dining room that is attached thereto, also can take away a large amount of air-conditioning gas, cause energy dissipation.
Task of the present utility model is the deficiency at above-mentioned hood, for the public kitchen in high-and middle-ranking hotel provides a kind of economical and practical multi-functional hood, it also has the induced air of generation, send multiple functions such as new wind, fire prevention, fire extinguishing and warning to the cook except that having filtration and mist extractor function.
The concrete measure of realizing above-mentioned functions is: the structure of multi-functional hood is formed, comprise shell, filter, exhaust blower and exhaust duct, shell longitudinally inboard is established an inclination demarcation strip and is separated out air supply plenum chamber, the air supply plenum chamber top connects blast pipe, the dividing plate lower end is bent into hook-shaped, the swash plate that is connected with the shell inside lower end forms bar seam air outlet, cook's air supplying hose is drawn in air supply plenum chamber, the end live splint horizontally slips on the chromium plating slide bar that is connected with the shell lower end, establish a side direction shower nozzle along the inboard long limit of shell point midway, shower nozzle is connected with the spray feed pipe, blast pipe and new blower fan group in the fan house, exhaust duct is connected with exhaust blower, advances, the Smoke proofing and fire proofing control valve is housed respectively on the exhaust duct.The Smoke proofing and fire proofing control valve adopts the Smoke proofing and fire proofing control valve on the air-conditioning system, is provided with five class and regulates air quantity, and its operating temperature is 93 ℃.There is miniature air grille the end of cook's air supplying hose, quantity-adjustable and wind direction.The side direction shower nozzle is a glass marble, and its operating temperature is 93 ℃.
This multi-functional hood is skillfully constructed, and is simple in structure, has multiple function.On former hood, increased air supply plenum chamber and bar seam air outlet, formed negative pressuren zone in the hood bottom, improved the efficient that captures oil smoke by short circuit air flow.Cook's air supplying hose has changed working environment for the cook.Fire prevention, fire extinguishing, warning device, in case breaking out of fire, the Smoke proofing and fire proofing control valve can manually or automatically cut out; Also can work as when temperature reaches 93 ℃ and close automatically, can export shutdown signal after closing, directly deliver to fire protection control center, after further examining the condition of a disaster, take corresponding fire extinguishing measure; When temperature reaches 93 ℃, be located at the broken automatic sprinkling fire-extinguishing of side direction shower nozzle on the shell, prevent fire spread.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Fig. 1 is multi-functional hood front view
Fig. 2 is the A-A cutaway view of Fig. 1
Fig. 3 is many hood scheme of installations
Multi-functional hood, comprise shell 1, filter 3, exhaust blower 11 and exhaust duct 15, shell 1 longitudinally inboard is established an inclination demarcation strip 16 and is separated out air supply plenum chamber 2, the air supply plenum chamber top connects blast pipe 14, dividing plate 16 lower ends are bent into hook-shaped, form bar seam air outlet 4 with the swash plate 17 of shell inside lower end welding, cook's air supplying hose 5 is drawn in air supply plenum chamber 2, prolonging the hood long side direction evenly distributes three, the end live splint is clipped on the chromium plating slide bar 6 that is connected with the shell lower end, and can horizontally slip on slide bar.Establish a side direction shower nozzle 7 along the inboard long limit of shell point midway, shower nozzle is connected with spray feed pipe 10.Blast pipes 14 are connected with exhaust blower 11 with new blower fan group 12, exhaust duct 15 in the fan house 13, advance, Smoke proofing and fire proofing control valve 8 be housed on the exhaust duct respectively, and it is provided with five class adjusting air quantity, and its operating temperature is 93 ℃.There are miniature air grille 18, quantity-adjustable and wind direction in the end of cook's air supplying hose 5.Side direction shower nozzle 7 is a glass marble, and its operating temperature is 93 ℃.But the hood separate unit uses, also can many in parallel uses.Fan house 11 is located at outside the public kitchen, opens earlier total exhaust blower 11 during use, opens new blower fan group 12 then, and each cook is according to the needs of oneself, and the manual adjustments hood advances, the Smoke proofing and fire proofing control valve 8 on the exhaust duct, generally once mixes up behind the air quantity motionless for a long time.The air quantity of cook's air supplying hose 5 can be regulated at any time.If have in many hoods several short-terms need not, but its Smoke proofing and fire proofing control valve on the airduct of temporary close.Total blower fan should be selected speed-changing draught fan for use, to adapt to load variations.When closing ventilating system on the spot during breaking out of fire in the kitchen.
Multi-functional hood, owing on shell 1, increased static pressure wind pushing box 2 and bar seam air outlet 4, because the air outlet place of bar seam air outlet has only 4 centimeters, wind speed is very high, forms a negative pressuren zone around it, has improved the efficient that captures oil smoke, resist cross-flow invasion, reduced exhaust air rate, improved ventilation efficiency, energy savings.
The special-purpose ajutage of cook is a condition of work of improving the cook, draws air supplying hose 5 in static pressure wind pushing box 2, can be on chromium plating slide bar 6 move left and right, adjust air supply direction.The time spent can not aimed at hood with air outlet.Increase air supplying hose 5, can be chef cook air-supply (being similar to the rotary supply outlet on the aircraft seat), cooling, for the cook creates a miniclimate district, prevent the oil smoke invasion and attack in the respiratory region, the protection cook's is healthy, has improved operating efficiency.
Often have on the naked light in the gastronomical process and scurry, the hood inner surface gathers grease easily and brings out fire.Because of on air-supply and exhaust duct, Smoke proofing and fire proofing control valve 8 being installed, employing be the Smoke proofing and fire proofing control valve of air-conditioning system, often open at ordinary times, be provided with five class adjusting air quantity, its control valve can manually or automatically cut out.In case when the exhaust case temperature reached 93 ℃, control valve can cut out automatically, and the output shutdown signal, this signal directly closes fire protection control center, takes corresponding fire extinguishing measure after further examining the condition of a disaster.Can manually opened Smoke proofing and fire proofing control valve after fire extinguishes.Extinguishing device at present each hotel public kitchen is only arranged shower nozzle at underfloor because the blocking of hood, shower water can not protective cover under cook zone.Set up the side direction shower nozzle at hood for this reason, when the oil smoke temperature reaches 93 ℃, the broken automatic water jetting of glass marble, shower nozzle communicates with water injection system in the kitchen, by the past spray of main building fire pump fire cistern pipe network water supply.
