Abstract

The utility model relates to a high-efficient flue exhauster with reduced flow area. The lower edge of the front baffle of the exhauster is 200 to 400mm higher than the lower edge of the left and right side plates, therefore the lower edge of the side plates is 50 to 200mm higher than the edge of the pot and a 300 to 600mm open space is provided above the pot with small flow area, halved power consumption and doubled suction capability. The utility model is low in cost, high-efficient and energy-saving in addition to convenient operation and beauty of art, with the side plates being possibly made of glass material. The utility model can better protect the kitchen environment if being used together with a smokeless pot with temperature indicator invented by the same applicant.

Description

Contracted flow leads to the efficient range hood of section type

Affiliated technical field

The utility model relates to a kind of range hood.

Background technology

Existing range hood installation site height (generally being higher than table top 650-700mm), left and right sides open wide, so flow area is big, often suction deficiency, efficient are low.In fact, after flow area was excessive, hot flue gas is the just simple rising thought of prior art but simultaneously with diffusion not only, so the top petticoat pipe of prior art can not be collected all oil smoke (unless continuing to strengthen power of fan).

Summary of the invention

For solving above deficiency, the efficient range hood that the utility model provides a kind of flow area to dwindle.

The technical solution of the utility model is: baffle plate lower edge, range hood front (operating surface) is than the best 250-350mm of the high 200-400mm in left and right side plate lower edge, during no front baffle plate is upper plate lower edge or positive lower edge, low level is installed and is made the side plate lower edge than the pot mouthful best 50-150mm of high 50-200mm, and make positive pot mouthful top that the open spaces of the best 350-450mm of 300-600mm be arranged, when pasting wall and installing because of wall is arranged, backboard lower edge and side plate lower edge can together can be uneven, and backboard lower edge status requirement is treated as the side plate lower edge when wall is installed.

The beneficial effects of the utility model are, because other face closure or open surface low discharge are little, the smoking effect is mainly by positive open area decision, because the minimum dimension that highly drops under the handled easily is opened wide in the front on pot top, realized that efficient is with rationally balanced easily, so, effective flow area of range hood work significantly reduces, increase the raising of suction enhancing efficient with power or with fume pollution weak spot under the flow (as outside pot mouth) flow velocity, simultaneously cost low (with existing the most frequently used side-mounting range hood than not increasing material consumption, especially also has reduced in the front), both sides are not shut and are made the side have a small amount of gas suction to avoid the inner left and right sides of range hood to form the dead angle and the material saving of oil smoke bumpy flow, and the scope that spills that side plate has also been isolated oil simultaneously helps keeping a public place clean.

Further specify below in conjunction with drawings and Examples.

Description of drawings

Fig. 1 is the front view of motor (blower fan) at an embodiment on range hood top, and Fig. 2 is its side sectional view, and what the M mark was arranged in the circle is motor, and the air outlet direction can be multiple and mark not; Fig. 3 is motor (blower fan) front view of an embodiment of side overleaf, and Fig. 4 is its side sectional view.For convenience of description, the pot that do not belong to range hood of having drawn among the figure, operating desk etc., but omitted and range hood parts that flesh and blood is irrelevant.

The specific embodiment

The front baffle plate can use transparent panel (as glass) or upper part opaque transparent as sanding/atomizing, lower part, also can be designed to move up and down the structure of (among Fig. 21 fix 1 removable) or upset (can overturn among Fig. 4), convenient observe again can be when no oil smoke be operated the increase operating space.The front baffle plate compresses flow area, and making pollution weak spot (outside pot mouth) [A] flow area that may spread flue gas reduce flow velocity increases, and [B] flow area big flow velocity in pot top reduces, the water evaporates of minimizing foodstuff surface helps fresh-keeping reduction heat waste.

Can there be a dodge gate [C, dotted line] in the front, another kitchen range of kitchen range cooking not with or when heating up water, close and can further reduce flow area behind the door.

(being that range hood bottom depth ratio operating desk depth is a few) best 100-150mm of 100-200mm or ratio pot mouthful outermost [A] indentation 50-100mm contract in the comparable operating desk outer in outer, side plate bottom, both sides [D], with handled easily and attractive in appearance but little to the smoking effectiveness affects, comparable bottom, side plate top is protruded (Fig. 2 Fig. 4 dotted line E) or is not protruded (Fig. 2 Fig. 4 solid line).

Side plate can contain light transmissive material (as glass) thereby the side can daylighting.

The form on (Fig. 1 right side promptly can) can be made and can be moved up and down to side plate, can reduce flow area when using single kitchen range cooking.

Can use single motor (blower fan), cost is low, has increased to the inboard fetch of pot to avoid the local excessive evaporation.Certainly also can with bi-motor.

Motor among Fig. 1 Fig. 2 (blower fan) is installed on top, the air inlet of range hood is preferably in depth direction (lifting mount type exception) in backboard 120mm, lead to the blower fan import by wind groove or airduct (dotted line of NM arrow points among Fig. 1 is the solid line of LM arrow points in Fig. 2).The range hood air inlet is different with the blower fan import, has broken the restriction of wind () machine installation site.Air inlet can be blocked in outside the sight line, does not decrease attractive in appearance and safer.Air inlet smoking point can inhale from the front L] and/or inhale [N] and/or tiltedly inhale [0] from inhaling down [M] and/or side, so the opening difference can be adjusted the suction of different directions.Because save the installation steel plate of the prior art products of motor side dress, become the used steel plate of air inlet and in fact also reduced the overhanging material that also do not increase of motor.

Use slim motor (blower fan) among Fig. 3 Fig. 4 and be loaded on rear side (metope side) [I], can add baffle plate [J] when air inlet is on the low side and stop that the bottom air intake reduces the inboard evaporation of pot to improve air inlet.

The convenient cooperation of air inlet installed silk screen [P], and the heavy oil cigarette that increases again attractive in appearance separates.Do not have barrier between oil smoke source and air inlet, it is clean that fuselage and printing opacity transparent material keep easily.The distance [fetch QR] of air inlet and baffle plate lower edge, front (during the baffle plate of no front is the upper plate lower edge): the ratio of the distance [fetch QA] of air inlet and outside pot mouth (weak spot) means that for a short time the path " short circuit " (by-pass shunt) that the velocity flow profile gradient is big, weak spot is lacked by fetch is many, the composition of blower fan power (flow) performance useful effect is little, efficient is low, and this ratio of the present utility model is obviously much bigger than prior art.And, the height of the utility model smoking port opening little (have can not enough 100mm), air inlet bore (about 250mm) when the prior art products motor side is adorned alleviates the shunting in the path that outside pot mouthful lacked by fetch when helping improving air inlet height (reducing the inboard evaporation of pot); Angle of flow [QR/QA angle] is little, the positive horizontal range of opening wide height even only being equivalent to outside pot mouthful (weak spot) and air inlet, and weak spot is to the fetch of air inlet and wait the fetch curved surface all to be compressed to the minimum state that satisfies under operating.These combinations have realized that really effective flow area minimizes.

Certainly, the utility model also can adopt the structure of the Western-style oil smoke type of installing by the smoke exhaust pipe lifting, electricity (wind) machine that is loaded on the top is in depth direction near backboard side (center of gravity in smoke exhaust pipe to keep balance), but upper plate can be put down also taper, the same printing opacity of backboard or transparent (as using tempered glass/overlay film plastics etc.) with side plate, backboard side plate lower edge is concordant, and the unique wall that both can paste is installed the characteristic that also can lift in the middle of the room, and changing layout need not change planes.

(motor top mount type contains the overhanging and about 450-600mm of motor sponson of air inlet to the high 350-550mm of the long 700-800mm of the utility model range hood representative configuration size, the lifting type contains the about 500-550mm of motor) dark 350-500mm, side-mounted range hood upper plate can be connected with the cabinet hanging cupboard, the flue lift-on/lift-off type is capable of hoisting under furred ceiling, its comparable flow area be about common range hood 1/3, only close behind the dodge gate 1/5, the power consumption effect that reduces by half doubles; Side plate indentation, side plate do not fall table top and side plate printing opacity transparent attractive in appearance, improved daylighting and little to the smoking influence, operating desk generally faces window, cooperate on every side the cooked parking space/high cube container of electrical equipment/life such as condiment lattice/microwave disinfection cabinet and with the concord of higher refrigerator etc., rational deployment and design cabinet, the range hood side plate does not only affect the appearance and also has special artistic grade, even lifting also has a distinctive flavour in the room.So the utility model is the breakthrough of matter, guaranteeing under easy to operate (cooking motion space, suitable height of observation, effectively observation) and the aesthetic, reduced flow area, energy-efficient, if the same applicant's of supporting use the Cooking pan with no smoke no fume that temperature indication is arranged then the kitchen environment protecting is better as far as possible.
