Abstract
A lampblack exhauster used in kitchens consists of a casing, a chimney, blowers, a smoke holding cover and an oil retaining coil, wherein, the chimney is positioned in the middle of the casing and is connected with a central hole of the lower bottom, and each of the two sides of the chimney which is arranged at the lower part of the casing is provided with a slotted hole; the blowers are arranged at the lower part of an upper top cover in the casing and at the two sides of the chimney, a tuyere of the blower is connected with the slotted hole of the chimney. The utility model which is a lampblack exhausting device applied in kitchens not only can exhaust the lampblack to the outdoors but also has the advantages of keeping the lampblack exhauster clean, no need of unpicking washing and no pollution caused by grease marks to the machine parts, which thus can keep the original working efficiency and prolong the service life.
Description
The utility model is the equipment of family kitchen sanitation and hygiene, is a kind of culinary smoke exhaust.
The utility model is before making, and family's kitchen smoke exhaust all is to utilize the rotation of driven by motor wind wing, oil smoke is extracted out outdoor by the rotation of wind wing.This mist extractor chance cause oil smoke to be attached on the wind wing and the electric drive axle of motor on and other positions.For a long time it, wind wing greasy dirt increases, arbor by oil stain, rotate unable, thereby operating efficiency reduces, and also reduces service life, therefore need often clean or unpick and wash.
The utility model its objective is a kind of separation cyclone type of design family kitchen smoke exhaust, makes its oil smoke discharge outdoor without power part.Cleaning in the maintenance machine, and oil stain mechanical part not, steady operation efficient increases the service life.
The utility model realizes that by following technical scheme its structure is by casing, formations such as pocket petticoat pipe, pressure fan, smoke evacuation tube, oil-collecting circle.A centre bore is respectively established in casing upper top cover and bottom surface center, and a pressure fan is respectively installed in the centre bore both sides, and the smoke evacuation tube is positioned at the casing middle part, promptly is installed on the bottom surface centre bore by the upper top cover centre bore.The bottom surface central hole is provided with the oil-collecting circle, and the pocket petticoat pipe is positioned at the casing below.
A rectangular otch is respectively opened in smoke evacuation tube corresponding position, lower bottom part both sides, its otch and an oblique angle that axially becomes 120 degree of discharging fume.
Pressure fan is to be made of motor, impeller and fan housing, and impeller is positioned on the arbor of fan housing motor below, and the air outlet of air blowing hood is tangential direction in smoke evacuation tube bottom two otch and engages.
Description of drawings:
Figure (1) the utility model structure content (normal cross-section) schematic diagram.
Figure (2) oil extraction chimney lower end two incision sites (master, side view) schematic diagram.
Air outlet of figure (3) pressure fan and smoke evacuation tube otch index map diagrammatic top view.
Be described in detail utility model structure content and operation principle in conjunction with the accompanying drawings below by embodiment.
Structure content: referring to Fig. 1, its structure is by casing (1), pocket petticoat pipe (9), pressure fan (5), smoke evacuation tube (3) and oil-collecting circle (2) formation.Respectively there is a centre bore casing (1) upper top cover and bottom surface center, and its aperture is consistent with smoke evacuation tube (3) bore, and casing (1) upper top cover centre bore two routine symmetries are respectively installed a pressure fan (5), are positioned at casing (1) upper top cover below.Smoke evacuation tube (3) is a cylindrical shape, and diameter is 150 centimeters, and long 45-50 centimetre is positioned at casing (1) middle part and promptly is connected together by casing (1) the upper top cover centre bore and the centre bore of going to the bottom.Form the oil smoke outlet.A kerf (4) (referring to Fig. 2) is respectively opened in smoke evacuation tube (3) lower bottom part two side corresponding positions, and its otch (4) is rectangle, and is about 5 * 7 centimeters, and otch (4) axially becomes 120 degree oblique angles with smoke evacuation tube (3).Pressure fan (5) is by motor (6), and impeller (8) and fan housing (7) constitute.Fan housing (7) is positioned at motor (5) below, and impeller (8) is positioned at fan housing (7), is installed on the arbor of motor (5) below, and fan housing (7) air outlet tangentially is tangential direction with smoke evacuation tube (3) otch (4) and engages (referring to Fig. 3).Casing (1) central hole tube (3) lower end of promptly discharging fume of going to the bottom is provided with oil-collecting circle (2), and pocket petticoat pipe (9) is positioned at casing (1) below.
Operation principle: when pressure fan (5) starts, send powerful high velocity air to smoke evacuation tube interior otch (4), because of wind is along the tangential direction in the tube and has the elevation angle to send into, so entering high velocity air counter-clockwise direction in tube of smoke evacuation tube (3) rotates up, form the high speed ascending air of rotation, and make a bottom opening produce blast upwards, the oil smoke suction end mouth that blast will enter in the pocket petticoat pipe (9) enters smoke evacuation tube (3), and discharges outdoor with the interior high speed rotation ascending air of smoke evacuation tube (3).
The utility model and prior art contrast are characterized in: the utility model adopts smoke evacuation So the structure that system and machine power parts and circuit are separated is not can oil stain and pollution Mechanical power member and circuit, while have also kept cleaning and health in the casing, do not need Often unpick and wash or clean, thereby also keep original operating efficiency and normal service life.
