Abstract
The utility model relates to a cooking fume remover, and the cooking fume remover comprises a housing, an exhaust section, and a power section. The cooking fume remover is characterized in that the worm gear of the power section drives the external cleaning air into the exhaust section to form a low pressure area and inhale the fume gas and expel the fume gas by exhaust the pipe. The utility model has the advantages that the gas dose not contact the worm gear and the electrical machine, which improves the durability of the hood, and the cleaning and repair are simple and convenient.
Description
The utility model relates to a kind of smoke exhaust, belongs to the kitchen cleaning apparatus.
The smoke exhaust that generally uses is to produce pressure to fall at the impeller inlet place at present, make oil smoke gas directly enter impeller, by impeller centrifugal force oil smoke gas is discharged through blast pipe again, because oil smoke gas need be discharged through impeller, housing and motor seal are bad in addition, cause smoke exhaust very easily to stick oil stain, both be difficult to clean, influence result of use again.
The purpose of this utility model is at the problems referred to above, provides a kind of oil smoke gas without impeller, directly the smoke exhaust of being discharged by blast pipe.
Smoke exhaust of the present utility model comprises discharge portion, power section and casing, it is characterized in that described discharge portion comprises blast pipe, the jet ring, inner conical drogue, overcoat and gas skirt, blast pipe, the jet ring, inner conical drogue is connected from top to bottom successively with gas skirt, shape face constitutes oil smoke gas passing away in it, cavity between overcoat and the inner conical drogue is an ejection cavity, the big end of jet orifice (import) uniform on the jet ring is communicated with described ejection cavity, its small end (outlet) is communicated with blast pipe, screen pack and oil collecting ring are housed on the gas skirt, described power section comprises motor, worm gear and spiral case, air intake opening is arranged on the spiral case, the spiral case outlet is communicated with the ejection cavity of discharge portion by connecting tube, and connecting tube is provided with one-way cock.When the driven by motor worm gear rotates at a high speed, enter the interior extraneous air of spiral case under centrifugal action, enter the ejection cavity of discharge portion through connecting tube, one-way cock, when producing pressure when the jet orifice of jet ring penetrates at a high speed, air falls, in blast pipe, form a low-pressure area, because the static pressure of low-pressure area is lower than the atmospheric pressure at gas skirt place, makes the oil smoke gas below the gas skirt be inhaled into inner conical drogue, and discharge by blast pipe through filter screen.
The utility model has the advantages that oil smoke gas directly discharged by discharge duct without worm gear, avoided oil smoke pickup worm gear, motor etc., the service life of having improved smoke exhaust, and make and clean convenience easy to repair.
Fig. 1 is the novel structural representation of this real sheet.
Embodiment: referring to Fig. 1, smoke exhaust of the present utility model comprises casing 1, the discharge portion of being made up of blast pipe 7, jet ring 8, inner conical drogue 9, overcoat 6 and gas skirt 11 and the power section of being made up of motor 4, spiral case 16 and worm gear 15.Blast pipe 7, jet ring 8, inner conical drogue 9 and gas skirt 11 from top to bottom are connected successively, shape face constitutes oil smoke gas passing away in it, cavity between overcoat 6 and the inner conical drogue 9 is an ejection cavity, be processed with 24 uniform constricted jet holes on the jet ring 8, the big end (import) of jet orifice is communicated with ejection cavity, its small end (outlet) is communicated with blast pipe, gas skirt 11 is a peviform, screen pack 12 is equipped with in its porch, gas skirt 11 peripheries are equipped with oil collecting ring 13, and the oil stain on the screen pack 12 can flow into oil collecting ring 13 along the longitudinal fiber of net.Motor 4 is installed on the motor cabinet 14, motor 4 upper ends are motor cover 3, several air inlet windows 2 are arranged on the motor cover 3, there is not screen pack on the window 2, spiral case 16 outlets are connected with overcoat 6 by connecting tube 5, connecting tube 5 is provided with one-way cock 10, one-way cock 10 is two thin plates that are hinged in the connecting tube 5, extraneous air is entered by the air admission hole on the motor cover 3, pore on motor cabinet 14 enters spiral case 16 through worm gear 15, be pressed into the ejection cavity of discharge portion again through connecting tube, inject blast pipe 7 through the jet orifice of jet ring 8.Be equipped with seal in each parts connection place of airway and seal, gas skirt 11 and inner conical drogue 9 are for being threaded, so that unpick and wash cleaning.
