The present invention relates to cooking apparatus.

The smoke exhaust ventilator of prior art has shallow type flat roof type smoke exhaust ventilator (United States Patent (USP) 5,027,790), dark type integral type smoke exhaust ventilator (China Patent No. 95224919 with band fume collecting chamber, 7) both common drawback are: (1) volume is big, hangs highly, and oil smoke is taken out unclean; (2) the adjacent people's of blower fan the crown, noise is big.For overcoming above-mentioned shortcoming, the inventor has applied for that in nineteen ninety-five one " split type kitchen cabinet smoke exhaust ventilator " (China Patent No.: ZL95229144,4) as shown in Figure 1, is characterized in that: blower fan is contained in outdoor, the kitchen noiseless; Not contain the blower fan volume little for smoking cover after the split, width dimensions has dwindled particularly, see from the side, it is a pancake separating kitchen ventilator of vertical type, be smoking cover below, top centre is rectangular flue, two limits are branch kitchen cabinets, because be uprightly flat, do not keep off the cooking sight line, therefore bottom smoking port setting height(from bottom) can reduce half, its distance is near, and draft is big, and smoking efficient improves 1 times, the inventor has also done an interesting test for this reason, has reached to fry the effect that capsicum also can't smell some pepper flavors.But also found split type following 2 shortcomings that yet exist: installation of (1) outdoor fan and maintenance trouble are unfavorable for its popularization; (2) blower fan knot greasy dirt often needs to clean, and this also is a common fault of prior art smoke exhaust ventilator.

At the above-mentioned problems in the prior art, main purpose of the present invention is: effectively reduce integral type the intrinsic big shortcoming of noise.

Second purpose of the present invention is to solve blower fan and do not tie greasy dirt and exempt from the cleaning problem.

The 3rd purpose of the present invention is to provide a kind of dependable performance, and assembling is fast, is fit to scale smoking port opening and closing device of giving birth in enormous quantities.

In view of the material that has oil pumper now is that thin plate adds the appearance spraying, have more than is needed what years, sprayed coating comes off, and steel plate gets rusty, and complete machine must be scrapped.So the 4th purpose of the present invention is to reduce production costs, and boosts productivity and service life.

Main purpose of the present invention is achieved in that

A kind of integral cupboard-type kitchen ventilator, comprise a smoking cover, the cover bottom surface has smoking port, it above this smoking cover a cabinet type flue, the flue of cabinet type flue and following smoking cover is connected, blower fan is contained in the cabinet type flue, and has a smoke exhaust pipe, it is characterized in that: the heat-resisting insulation material layer that is surrounded by one deck 50 millimeter around the blower housing in cabinet type flue.

As follows to described feature description: the bag acoustic material is still initiated on the blower fan of integral type smoke exhaust ventilator, why it becomes possibility, just because of this integral cupboard-type kitchen ventilator design feature determined, it is the integral cupboard-type kitchen ventilator of a vertical type pancake or vertical type shape wide at the top and narrow at the bottom, the front and back horizontal width B on smoking port plane, bottom is the 220-320 millimeter at the bottom of the smoking cover, because the shared spatial volume of acoustic material is the spatial volume on the vertical direction of upright flat oil pumping cover, it does not increase the size of the width B before and after the smoking cover, reduction that can overslaugh smoking port setting height(from bottom), thereby also can not hinder the raising of smoking efficient.And wrapping the puigging of 2 * 50 millimeters of one decks before and after on the horizontal smoke exhaust ventilator of prior art again, size of width B will increase to the 600-650 millimeter from original 500-550 before and after it, will meet and discuss more, can influence the sale of its product because of operating inconvenience.So, do not adorn sound arrester in the existing integral type smoke exhaust ventilator, its reason is to be subjected to the restriction that the horizontal width increases.This also is the structural distinguishing characteristics why integral cupboard-type kitchen ventilator provided by the present invention can effectively reduce fan noise.Prevent from the overheated too thin 10-15 of the having only millimeter of thermal insulation layer of condiment product in the kitchen cabinet from can not blower fan be played effective deadening as for original conduct in the kitchen cabinet flue.Described heat-resisting acoustic material has the glass silk flosssilk wadding, rock wool, and the fluffy cotton of terylene, hollow polyester cotton or needle punched non-woven fabrics also can be wrapped one deck galvanized sheet or aluminium matter glass fabric again in the acoustic material outside.

Unusual characteristics to above-mentioned feature also have: as can be seen from Figure 2, the setting height(from bottom) H of smoking cover smoking port can be reduced to 400 millimeters from existing 800 millimeters, key just is that the front and back horizontal width B on its smoking port plane can narrow down to below 320 millimeters, greater than 320 millimeters, will block the cooking sight line of cooker, B is less than 220, and smoking port is too too big by wall and frying pan center deflection, and smoking efficient is also bad.As everyone knows, pumping efficiency is square being inversely proportional to of distance of bleeding with it, and this is a simple law on the aerodynamics.Hang lowlyer, smoking efficient is higher.The upright integral type smoke exhaust ventilator of the present invention that Here it is and prior art horizontal integral type smoke exhaust ventilator different distinguishing characteristics, also be an inventive point of the present invention.

Second purpose of the present invention is achieved in that in the flue system before cabinet type flue blower fan auto-cleaning and screen net type oil filter is housed.Its distinguished characteristic is: because the smoking and the cabinet type flue installation degree height of integral cupboard-type kitchen ventilator are low, near from burning things which may cause a fire disaster, be contained in the screen net type oil filter in this place's smoking port or the cabinet type flue, its oil smoke temperature height, setting temperature much larger than this place's oil smoke, the good fluidity of oil droplet, can not tie greasy dirt on the mesh, also can utilize the temperature thermal energy of oil smoke self to reach the function of auto-cleaning and screen net even tied greasy dirt, the screen net type oil filter in Here it is the utility model integral cupboard-type kitchen ventilator and the screen net type oil filter of prior art smoke exhaust ventilator have the distinguishing characteristics of difference in functionality, key is it is where to be contained in, result of the test has also confirmed this point, thereby the inventive application with new function is worth, with regard to patent, any Devices Characteristics all is the temperature with its installation present position, conditions such as pressure are relevant, are not that all screen net type oil filters all have automatic cleaning function, just people do not recognize the factor of their inherences, can't be used.

Described screen net type oil filter following two kinds of structures are arranged: (1) board plug type screen net type oil filter; (2) pocket type screen net type oil filter.Wherein, particularly a kind of board plug type silk screen oil strain cigarette of splitting of the single or multiple lift that is contained in cabinet type flue lower end import department is compared with the pocket type oil filter and is had more new substantial advantage, this be because: (1) the former to be installed in cupboard flue lower end import department lower than the position of the pocket type oil filter that is contained in cupboard top, the temperature of oil smoke of living in is than latter Yao Genggao, the flowability of oil droplet is better, and mesh is more difficult to be stopped up by greasy dirt; (2) cabinet type flue lower end import department split the board plug type screen net type oil filter change convenient, need only old silk screen plate be taken out from smoking port, and push new silk screen plate, and need not tear machine open and just can change, the latter then must ask special mechanic to open top cover to the doorstep and could change.(China Patent No.: 96225618) compare another advantage that is had is pocket type screen net type oil filter under screen net type oil filter in the described flue and the prior art smoke exhaust ventilator smoking port of hanging highly: after latter's mesh has amassed the pasty state greasy dirt, seem very dirty, unhygienic, even having amassed, the screen net type oil filter in the former flue puts dirty black sump oil, the outside also be cannot see, do not influence the clean and tidy health in kitchen, have more coml and be worth.

There is not the cold district of heating can clean silk screen in the winter time by manually heating yet, method is: remove frying pan, directly suck combustion gas from smoking port, in cabinet type flue and be provided with the heat indicator of an artificial heating of monitoring, best artificial cleaning temperature is controlled at below 50-80 ℃, in order to avoid burn out the plastics exhaust tube on the cabinet top.Also can before artificial heating, open blower fan earlier, under the situation of not opening combustion gas, spray into kitchen cleaning agent, spend a quarter of an hour from smoking port, treat that greasy dirt is dissolved after, carry out artificial heated wash again, effect is better.The material of silk screen can be selected for use: stainless steel wire, and galvanized wire, copper wire, the hot nonwoven of combustion is burnt in fire-retardant chemical fibre silk and resistance.

It is reliable that the 3rd purpose of the present invention provides a kind of serviceability; assembling is fast; be fit to the smoking port opening and closing device that scale is produced in enormous quantities; this purpose is achieved in that and the invention provides a kind of smoking port turnover shutter device; it is characterized in that pinning and do not fall the locking mechanism that gets off after valve plate open to promote after rise and comprise two kinds of permanent magnet locking mechanism and spring clip locking mechanisms; the former directly is absorbed and fixed under the cowl top panel by its permanent magnet pieces; or under the support under the cowl top panel; during unlatching; when valve plate or turning arm promote when running into permanent magnet pieces; promptly being held locking does not fall after rise; when closing; by the opposite spin button, valve plate or turning arm break away from permanent magnet pieces and fall after rise, and seal smoking port.Support can be with constant slope fixed, also can make the movable support of the angle that can rock back and forth.The contact area of requirement permanent magnet pieces and cowl top panel or the adsorption area of permanent magnet pieces and support must be greater than the adsorption areas of permanent magnet pieces and valve plate or permanent magnet pieces and turning arm, for example the former is the face contact, the latter becomes line to contact with the rotation arm axle, with the adsorption area that guarantees the former greater than the latter.Permanent magnet pieces just can not left behind with the latter's falling.The annealing temperature of permanent magnet is more than 300 ℃, in the smoking cover oil smoke temperature only 50-80 ℃ thus permanent magnet pieces can use for a long time and not demagnetize.Greasy dirt does not have separated magnetic effect, can not influence its suction behind the long-pending greasy dirt yet.

Latter's spring clip type locking mechanism, its spring accompany three kinds of structures: (1) opening garden ring type spring clip; (2) bilateral spring clip; (3) one-sided spring clip.Under smoking cover 50-100 ℃ temperature, reach the annealing temperature of spring far away, so spring clip can not follow the string because of annealing, can use for a long time.

The 4th purpose of the present invention is achieved in that smoking cover, and cabinet type flue and Fan casing partly or entirely adopt the engineering plastics moulding to replace steel plate punching press splice.The advantage of engineering plastics is that cost is low, the productivity ratio height, and non-corrosive, the life-span is long.

The present invention compares the advantage that is had with the prior art smoke exhaust ventilator: it is low that (1) had both had the separating kitchen ventilator setting height(from bottom), and the advantage that smoking efficient is high has the shallow type of integral type again or advantage is easily installed and unpicked and washed to dark type oil pumper; (2) auto-cleaning and screen net type oil filter is housed, blower fan is not tied greasy dirt, exempts to clean, and safeguards simply, has guaranteed smoke exhaust ventilator high-efficiency operation all the year round simultaneously; (3) the blower fan periphery in the cabinet type flue has been packed puigging and can effectively have been reduced the big shortcoming of the traditional noise of integral type; (4) smoking port opening and closing device magneto locking mechanism dependable performance is fit to scale and produces in enormous quantities; (5) replace steel plate with engineering plastics, cost is low, the productivity ratio height, and the life-span is long.
