Abstract

The utility model provides a no oil stick kitchen fan which is on the upper part of the ring tube; along the upper part of the ring are positioned a plurality of air outlets facing upwards; the oil smoke cover is covered on the upper part of the ring tube, and covers the air outlets; out of the oil smoke cover on the upper part of the ring tube is arranged an air inlet; on the upper part of the air inlet is provided with a fan opposite to the air inlet; on the central top of the oil smoke cover is arranged an exhaust tube. When starting the fan, the air through the air inlet is blown into the ring tube; after the ring tube being filled, the air is dispersed through a plurality of air outlets on the ring tube; the dispersed air is discharged through the exhaust tube facing the oil smoke cover on the oven, and the oil smoke produced by the oven is taken away, so most of the oil in the smoke is directly taken away and is not stick on the inner surface of the oil smoke cover; if on the top of the exhaust tube is arranged a transverse exhaust smoke pipe communicating with the exhaust tube and on one end of the exhaust smoke pipe is arranged a fan, the air flow produced by the fan will produce the negative pressure on the top of the exhaust tube to take the oil smoke away for discharging the oil smoke more smoothly.

Description

Non-oil stick cooking fume exhauster

Technical field

The utility model belongs to daily necessities, and specifically a kind of culinary oil that makes is difficult for sticking to smoke exhaust on the cover.

Background technology

Can produce a large amount of oil smoke during the kitchen cooking, work the mischief to health, so people have invented fume exhausting fan, but when the flue gas that has big gauging during through petticoat pipe, oil can stick to the inwall of petticoat pipe, is difficult to dispose.

The utility model content

Stick to the problem that the petticoat pipe inwall is difficult to dispose for solving tobacco tar, the technical solution of the utility model is: on the top of an annular canister, there is the air outlet of opening on a plurality of in top branch along annular, and oil smoke cover covers on the top of annular canister, and with the air outlet cover within it; Outside the oil smoke cover on annular canister top, leave air inlet, be installed in the fan that the subtend air inlet is arranged at oil smoke cover top, chimney fan is installed in the top center of oil smoke cover in the upper support of air inlet.

More smooth and easy for mist extractor, on the top of chimney fan the transverse row smoke pipe that communicates with it is installed, an end of smoke exhaust pipe is equipped with ventilating fan.

During use, open fan, after being full of in air inlet is blown into annular canister, disperses air through a plurality of air outlets on it, the chimney fan that is flung top by the oil smoke cover of air through kitchen range top after disperseing is discharged, the oil smoke that kitchen range are produced is taken away simultaneously, the oil overwhelming majority in the flue gas is directly taken away and can not be sticked on the inner surface of oil smoke cover like this, greatly reduces the number of times that oil smoke cover is removed; If on the top of chimney fan the transverse row smoke pipe that communicates with it is installed again, an end of smoke exhaust pipe is equipped with ventilating fan, and then air-flow that ventilating fan produces produces negative pressure on the top of chimney fan and takes away oil smoke, and mist extractor will be more smooth and easy.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a cross-sectional schematic of the present utility model;

Fig. 2 is the A-A cutaway view of Fig. 1.

The specific embodiment

Among Fig. 1, on rectangular closed ring tube 1 top that adapts with kitchen range, along the top branch of annular a plurality of air outlets that make progress 2 are arranged, described air outlet 2 can be circular hole, elliptical aperture, can also be elongated hole; Oil smoke cover 5 covers on the top of annular canister 1, and within it with air outlet 2 (referring to Fig. 2) cover, annular canister 1 top is outside oil smoke cover 5, leave air inlet 3, this air inlet 3 can be the hole that opening makes progress, can also be communicate with annular canister 1, tube that opening is upwards installed, air inlet 3 can be one, also can be positioned on the diagonal angle of annular canister 1 or opposite side a plurality of, preferably be installed in two of diagonal angle; The cover 6 that is buckled on the air inlet 3 and communicates with atmosphere is arranged at the top outside oil smoke cover 5, and fan 4 subtend air inlets 3 are bearing on the cover 6, in the top center of oil smoke cover 5 chimney fan 7 are installed; Annular canister 1 its cross section of described sealing can be square, D shape, also can be oval or other shapes, and its four jiaos was fillet when closed ring tube 1 was square.

More smooth and easy for oil smoke discharge, on the top of chimney fan 7 the transverse row smoke pipe 9 that communicates with it can be installed also, an end of smoke exhaust pipe 9 is equipped with ventilating fan 10.

For preventing the suction transverse row smoke pipe 9 of foreign material, be enclosed in the end of smoke exhaust pipe 9 at the also available screen cloth 11 in the outside of ventilating fan 10.

The above-mentioned specific embodiment is not the qualification to the utility model protection domain, and according to the main order of its innovation and creation, the specific embodiment can be done multiple variation.
