Abstract

The utility model relates to a cooking-fume exhauster which can exhaust cooking fume through double surfaces, and the utility model belongs to the class of a kitchen device. The proposal is provided for overcoming the problems that cooking fume above the cooking-fume exhauster can not be exhausted by the existing cooking-fume exhauster and oil pollution stuck on an impeller is not easy to clean. The utility model is composed of a casing of the cooking-fume exhauster, an impeller, an air guide casing of the impeller, a drive motor and a cooking-fume exhaust pipe, wherein, a cooking-fume suction window on the impeller of the utility model is upwards arranged, and upper cooking fume can be sucked in; an overlapping opening of an impeller casing and the cooking-fume exhaust pipe is provided with multiple layers of air guide plates, airflow is made to be upward, and the cooking fume on the lower part can be sucked in and exhausted together by negative pressure caused by the upward airflow on the lower part of the pipe. An experiment shows that the product of the proposal has the characteristics of stable performance and good cooking-fume exhaust effect.

Description

Smoke exhaust that can two-sided smoking

The utility model belongs to the cooking apparatus class, and it is specifically related to a kind of structure of novel smoke exhaust.

Along with the rapid raising of people's living standard, the use of household electrical appliance is very general, and the smoke exhaust in the kitchen is exactly an example.The window of the suction oil smoke of general mist extractor down, the external smoke discharging pipe of the opening above the smoke exhaust housing.There is following problem in such smoke exhaust: it can only discharge the oil smoke below the smoke exhaust housing, then incompetent this power of oil smoke above it, and the user can only set an air draft door leaf again on the window of kitchen eminence, otherwise indoor cigarette is still a lot; In addition, oil smoke during culinary art and steam all suck and discharge from impeller, a large amount of greasy dirts all is trapped in impeller and the local part surface in addition of other oil smoke process, when greasy dirt accumulates too much, the throat sound of smoke exhaust is strengthened, make the ineffective and increasing load of motor rotation, long this is easy to burn motor before, and each parts that often cleans smoke exhaust are very annoying things.Know that through investigation present smoke exhaust all adopts the structure of the direct air draft of impeller, therefore two above-mentioned technical problems just can't overcome.

The purpose of this utility model is to provide a kind of novel smoke exhaust, and it can get rid of the oil smoke on its top, and main oil smoke can be avoided the difficulty of impeller cleaning without impeller.

By as above design, this programme provided can two-sided smoking smoke exhaust comprise the smoke evacuation impeller, drive motors, the smoke exhaust housing, inner impeller wind-guiding housing, smoke discharging pipe, the window opening that it is characterized in that its two impeller end face oil suction cigarettes makes progress, its smoke discharging pipe also is located at the meet of two impeller housings, and pipeline is open-minded outside the both ends of the surface up and down of smoke exhaust housing, its upper end open connects outside smokejack, the opening of bottom is for inhaling the window of oil smoke on the kitchen range, have passage at smoke discharging pipe and two impeller wind-guiding housing intersection places, wind deflector is housed at the open channel place of smoke discharging pipe.

Smoke discharging pipe in this programme is a cylindrical shape, open four to six rectangular apertures on the tube wall of it and two impeller wind-guiding housing intersections, wind deflector is the taper seat of a part, the mean radius of its taper seat equates with the radius of smoke discharging pipe, have the perpendicular muscle welding that rectangular indentation and smoke discharging pipe opening part stay on the middle part of every wind deflector and both sides fixing, and the osculum of its tapering up.Its wind deflector is provided with 2～4 layers altogether.Also can install the top flue on its oil suction smokestack mouth of upwards opening at two impeller places, it is the light-wall pipe of a vertical top band guard, and fresh air inlet is arranged on cylinder.

Adopt this programme can embody following superiority: 1. the window of the impeller of this kind smoke exhaust suction flue gas up, can suck the flue gas above the smoke exhaust housing, if smoking window place increases the top flue on two, also can strengthen the effect that the eminence flue gas is sucked; 2. the flue gas of two impellers suction enters smoke discharging pipe through wind deflector, because wind deflector is inclined upwardly in wind path, its distinguished and admirable making progress is discharged through the smokejack of outside, this moment, the distinguished and admirable smoke discharging pipe end opening that causes at a high speed had certain negative pressure, like this, the end opening of smoke discharging pipe can be discharged the oil smoke of smoke exhaust bottom, and its main oil smoke is discharged without impeller, therefore do not pollute impeller, the hardship that can avoid cleaning impeller; 3. it has the characteristics of novel form, simple in structure, low cost of manufacture, is convenient to promote the use of.

Fig. 1 is the outline drawing of the smoke exhaust that this programme can two-sided smoking.

Fig. 2, Fig. 3 are the structural representations of the smoke exhaust of this programme, and Fig. 3 is the side view of Fig. 2.

Fig. 4, Fig. 5 are the schematic diagrames of its smoke discharging pipe, and Fig. 5 is the B-B view of Fig. 4.

The embodiment of existing accompanying drawings this programme.This programme can two-sided smoking smoke exhaust formed by smoke exhaust housing 3, centrifugal smoke evacuation impeller 1, inner impeller wind-guiding housing 4, smoke discharging pipe 5.The window of its two impellers and the smoking device that makes progress, the opening part that its smoke discharging pipe and two impeller housings intersect is equipped with wind deflector 6, wind deflector is cone-shaped, establish 2～4 layers altogether, because wind deflector is to tilt to install, the distinguished and admirable guiding that it forms impeller is upwards discharged, and smoke discharging pipe is the lower ending opening outside housing also, end opening at smoke discharging pipe when high velocity air is upwards discharged causes negative pressure, discharges in the lump after the flue gas of smoke exhaust bottom can being sucked.The impeller of smoke evacuation and the window of smoking are upwards, so the flue gas of smoke exhaust top can be siphoned away, this be other smoke exhaust can not for, in order to strengthen its effect, window place at the oil suction cigarette on top can install top flue 7 again additional, it is a sheet-metal duct that certain altitude is arranged, and its cylinder is provided with fresh air inlet.Because the flue gas of main culinary art enters without impeller, so the contaminated degree of impeller is very low, so can avoid cleaning the hardship of impeller.The pilot sample of this programme proves that through running experiment it has stable performance, smoke discharging effect is good, especially can discharge the characteristics of the flue gas on smoke exhaust top.
