Abstract
The utility model discloses a household centrifugal jet type range hood, which is structurally characterized in that an isolation chamber and a gas collection cavity for collecting oil smoke are arranged in a shell with an air inlet and an air outlet. The isolating chamber is provided with an exhaust port and is connected with a fluid air channel, an outlet of the air channel is arranged in the air collecting cavity, and compressed air generated by the air blower is directly sent into the air collecting cavity through the fluid air channel. In order to increase the exhaust effect, a reducing nozzle can be arranged at the tail end of the fluid air duct. The utility model discloses because motor and centrifugal fan thoroughly keep apart with the oil smoke, therefore no longer need clean.
Description
The utility model relates to a kind of exhaust apparatus of cooking flue gas, especially relates to a kind of smoke exhaust.
Improve constantly with first people's living standard, smoke exhaust has become requisite Kitchen hygiene sanitary equipment.The smoke exhaust that present family generally adopts is the fan-type fume exhausting fan, the structure of this lampblack absorber is that motor takes the blast fan rotation to, the blast fan that makes smoke exhaust is directly to the oil smoke work done, thereby a large amount of greasy dirts deposits on blast fan and the motor, pipeline is interior etc., so that be difficult to clean and maintenance, the serious load because of motor is excessive to cause the motor damage to be scrapped.
The CN2129898Y utility model patent discloses a kind of range hood of exempting to clean, and it just adds a greasy dirt filter assemblies at the place, air port of common lampblack absorber, thereby, not from defective according to the common lampblack absorber existence of last solution.
The disclosed fume exhaust device of CN2118931U notification number, it connects air blast and blast pipe by a cylindrical reducing tee member respectively at axial two ends, air intake duct of ejector indirect, air intake duct and fume exhaust cover are connected.Though the smoke exhaust oil smoke of this structure does not pass through air blast, but drives oil smoke discharge by the air blast jet air indirectly by air intake duct, so its inefficiency, the mist extractor effect is bad, is difficult to reach hygienic requirements.
The utility model adopts compressed air directly to drive oil smoke discharge according to principle of hydrodynamics, and its objective is provides a kind of smoke exhaust that need not clean, to overcome the problem that above-mentioned prior art exists.
The utility model is included in the housing of the smoke exhaust that is provided with the inlet and outlet mouth and is equipped with air blast, this air blast is made up of motor and centrifugal fan impeller, its design feature is that said air blast is arranged in the isolation ward that is processed with the inlet and outlet mouth in the housing, the exhaust outlet of air blast connects the air fluid air channel, this ducting outlet is located in the housing air collecting chamber, and the air driven oil smoke that discharge in the air channel rises by the exhaust of air collecting chamber gas outlet.This smoke exhaust produces compressed air by air blast and directly sends in the air collecting chamber by the fluid air channel according to aerodynamic principle, utilizes the high-velocity fluid injection to collect oil smoke, and the gas outlet and the tube connector thereof that make oil smoke pass through smoke exhaust are discharged outdoor.
The outlet end in above-mentioned fluid air channel can be equipped with at least one undergauge jet nozzle, utilizes the jet nozzle self-characteristic, further improves the flowing velocity that fluid enters air collecting chamber, makes air conduction produce bigger suction force, collects oil smoke in the kitchen better.Above-mentioned jet nozzle can be designed to annular shape, zigzag or other suitable shape according to lampblack exhauster structure.Jet nozzle distribution installation site and angle can select best injection effect position of generation and angle to install according to the air collecting chamber inner wall shape.
This smoke exhaust can be selected single-drum wind list air channel structure, also can select the two air channel structures of dual blower.The utility model adopts isolates motor and blade wheel structure thereof, thereby, make a large amount of greasy dirts accumulate in smoke exhaust inside guaranteeing to have avoided traditional smoke exhaust directly to aspirate oil smoke under smoke exhaust operating efficiency and the mist extractor effect prerequisite, not only be difficult to clean, and maintenance difficult.This lampblack exhauster structure is simple, and is convenient and healthy, for ease of maintenaince.Because air collecting chamber is that tubular should not accumulate greasy dirt, though the chamber wall slightly greasy dirt also be convenient to clean.This smoke exhaust can be designed to horizontal, vertical two kinds of structures according to user's needs.This smoke exhaust can be used as ventilation fan simultaneously and uses, and the smoke exhaust inlet port is communicated with the parlor with pipe or can take a breath in the bedroom.These characteristics are another advantages that existing traditional smoke exhaust can't be by comparison.
Introduce embodiment of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is the horizontal lampblack exhauster structure schematic diagram of the utility model unit.
Fig. 2 is the vertical lampblack exhauster structure schematic diagram of the utility model unit.
Fig. 3 is the horizontal lampblack exhauster structure schematic diagram of the utility model two-shipper.
Embodiment 1:
Embodiment 2: be the smoke exhaust of the two air channel structures of two-shipper.Its principle is identical with the smoke exhaust of unit list air channel structure.Just air blast and fluid air channel are two, and jet nozzle also increases to 6 accordingly, and the effect of discharging oil smoke like this is even more ideal.
Claims (3)
