Description

Range hood

The utility model relates to a kind of equipment that is used for kitchen pump drainage oil smoke, especially a kind of range hood.

The wider a kind of range hood of Ceng Liuhang on the market, its beautiful shape, luxurious, price be more than 1000 yuan, generally is installed in the kitchen on the kitchen range top, oil smoke is discharged outdoor by ventilation duct, this range hood is because the deficiency of aspects such as power, angle, design causes the smoke pumping effect bad, and volume is big in addition, need account for the kitchen certain space, install complicated, the difficult cleaning of greasy dirt, it is all multifactor that price is more expensive etc., progressively eliminated in recent years.

At present, the substitute material of ventilation fan as range hood generally adopted in general kitchen, this ventilation fan generally by housing, circular flue, be installed in the motor on the support that is connected as a single entity with housing and be installed on the motor shaft and the blade that matches with flue, the barge board that is installed in the louvre type on the housing of outdoor are formed.This ventilation fan generally is installed on the window page or leaf of kitchen, 0.5 meter left and right sides, cooking stove top exterior wall.This ventilation fan volume is little, and price is low, installs simply, does not account for kitchen space, and the smoke pumping effect is better than above range hood.But this ventilation fan of using as smoke extractor, still there is following defective: when one, this ventilation fan is worked, because the deadweight and the factors such as angle and power of motor of outdoor barge board, barge board can not be vertical with surface of shell in actual the use, generally can only open 30～60 degree, promptly still have very big resistance, when particularly big or greasy dirt applied too much when outdoor wind, wind-force almost can't be opened outdoor barge board; The flue outlet place is uncovered in addition, and the indoor side air intake can not be concentrated relatively, so the smoke pumping effect is still undesirable, when particularly strong wind weather and greasy dirt were too many, the smoke pumping effect was almost nil.Two, because this ventilation fan does not have sharp oily guide channel and oil catcher, inside and outside equal greasy dirt is had one's face covered with, also be that greasy dirt is expired wall on the inwall of kitchen.

The purpose of this utility model is to provide that a kind of both volumes are little, installation simply, does not account for kitchen space, price is low, is not subjected to weather effect again, has desirable smoke pumping effect and keeps the kitchen not have that oil smoke, inside and outside body itself reach bottom window page or leaf, wall does not have greasy dirt and cleans range hood easily.

The purpose of this utility model is achieved in that this range hood comprises: be installed in the housing on the kitchen exterior wall window page or leaf of about 0.5 meter of cooking stove top, circular flue, be installed in housing be motor on the support of one and the blade that is installed on the motor shaft and matches with flue, big outer conelet degree extended to the outdoor in flue was, and was characterized in: the outlet port, the outside of flue is provided with the closing in towards flue circle center; Support is positioned in the closing in outerplanar line, and apart from least 4 millimeters on outerplanar line, the bottom of motor is provided with the Oil Guide pad of the two stands that Residual oil can be led, and inboard surface of shell is provided with sharp oily protruding circle; The bottom of indoor side housing is provided with the Oil Guide oil line to lower convexity, and interior side body lower end is provided with detachable oil trap; Interior side body top is provided with to open and places the housing front upper place or close the cover plate that holds together to cover at surface of shell.

Owing to adopt above structure, the utlity model has following remarkable advantage and good effect:

One, owing to cancelled the outdoor baffle plate, increased the cover plate of side body front upper place in placing, to block the top air flows downward below air flows is accelerated, the more important thing is that outlet port, the flue outside is provided with closing in, make air along the very fast formation eddy current of blade sense of rotation that cooperates with flue, and then improve wind speed (wind-force can reach 3 meters of per seconds), reduce resistance, make chimney intake form one suction, thereby has a desirable smoke pumping effect, can thoroughly take oil smoke fast away, and it is smokeless to keep not having oil in the kitchen.Two, because oil smoke is extracted out outdoor with flue fast, so oil droplet is detained range hood itself seldom, oil trap and sharp oily protruding circle and the outside design of the Oil Guide tracks such as oily line of particularly setting up Oil Guide pad and projection of closing up in addition, even residual greasy dirt is arranged, also natural following current is advanced groove and can not polluted indoor exterior window page or leaf and wall.When three, this pumping unit is not worked, can cover cover plate, not only increase attractive in appearance but also can prevent in mosquito, the mouse inlet chamber, also can be windproof, antitheft.Four, the advantage that has kept the ventilation fan that the original work range hood uses: volume is little, and price is low, installs simply, does not account for kitchen space.Five, compare with former ventilation fan, this range hood power is big, and energy-conservation (existing one can be supported former two), it is convenient to clean, and can be widely used in kitchens such as family, hotel, dining room.

Below in conjunction with drawings and Examples the utility model is described in further detail.
