Description
Technical field
The present invention relates to kitchen utensils technical field more particularly to a kind of range hoods.
Background technology
At present, the generally double stoves used in subscriber household, there are two burners for left and right.The cookware of cooking is in the two of smoke machine
Side, and general range hood is in air inlet and air inlet only there are one putting, in the air inlet put generally be difficult by the oil of both sides
Cigarette suction is clean.
In view of the above-mentioned problems, current technical solution is generally solved using increase smoke collecting chamber or so, front and rear size.
The increased smoke collecting chamber of size can form a certain size tobacco control region, and stock size is bigger, and tobacco control region is bigger, such as certain brand
Series connection wind turbine is exactly in the case where air quantity promotion has bottleneck, and the side-to-side dimensions for holding together smoke chamber have been accomplished 1000mm.In market
Existing range hood holds together the side-to-side dimensions of smoke chamber generally between 600~1000mm, and anteroposterior dimension is between 350~550mm.
But the size of smoke chamber, the limitation of smoking effect enhancing are held together in simple increase.And the side-to-side dimensions for holding together smoke chamber are limited to stove
The influence of the factors such as anteroposterior dimension, cabinet size, the size of kitchen space and the user's operation convenience of platform, side-to-side dimensions are excessive
Most family of China is not suitable for it, general recommendations side-to-side dimensions are 895mm.So hold together the increase of smoke chamber to smoking effect
It is more to act on limited and limitation.
In addition, that the water conservancy diversion set on the babinet of range hood there are one elongated cavity also can be used is hardened for current technical solution
Structure, specifically as shown in Figures 1 to 4,100 complete machine of range hood is mainly by check-valves 101, babinet, deflector 102, cold plate
103rd, the components such as Inlet Network 105, lubricating cup 104 form, and fan assembly are equipped in babinet, fan assembly is mainly by spiral case 107, motor
108 and 109 grade components of impeller form；An air inlet is equipped at the middle part of elongated cavity, is overlapped with the air inlet of spiral case 107, to increase
Strong smoking effect can add cold plate 103 in 102 front end of deflector, and the presence of cold plate 103 causes air-flow along cold plate
103 surrounding air inlet so that the flue gas that both sides cookware generates enters cigarette by the air inlet runner of the left and right sides of cold plate 103
Inside machine, specific flue gas flow direction 106 can be obliquely installed referring to Fig. 3, and by spiral case 107 so that the air inlet of spiral case 107 and rising
The distance of flue gas is closer to be further beneficial to enhancing smoking effect.But deflector using the above structure, easily cause air quantity
Loss and noise increase, and cold plate is added so that flow disperses in cold plate surrounding, is unfavorable for oil smoke during quick-fried
Complete pump drainage.Particularly, the situation for running cigarette can occur in quick-fried in the subregion of cold plate surrounding, need to be mended with flow, flow velocity
It fills, and the increase of flow and flow velocity causes noise to increase, user's audio experience is very poor.
In addition, the setting of spiral case parallel connection also can be used in range hood in current technical solution, two wind turbines are symmetrical
It places.It is of high cost, efficiency is low, smoking effect increases under big back pressure using the method that two motors are set at left and right sides of range hood
Added with limit；And two independent blower fan systems, it can be tired there are whole wind pressure the phenomenon that air inlet interference, is caused to be promoted in air inlet front end
It is difficult.In addition, under equal air quantity, two fans noise will be far above single-fan system, and two fans system not can solve
Oil fume pump exhaust problem under larger pipeline back pressure.
