Abstract
The invention discloses a concentric-double-square-shaped vortex fume exhaust system used on an air exhaust and oil fume exhaust product, belongs to oil fume exhaust equipment, and aims at solving the problem that an existing oil fume exhaust system is relatively small in oil fume sucking range. According to the vortex oil fume exhaust system provided by the invention, an air inlet guide passage communicated with an air inlet is arranged on a volute, fixed spiral guide fan blades are arranged in the end hole of the air inlet guide passage; during work, guide air flow spirally enters the end hole of the air inlet guide passage, meanwhile, a vortex is generated at an air inlet in a pressed way, and drives abundant air flow to continuously enter the volute, so that integral sucking force of an oil fume exhauster is powerful, the oil fume sucking range is large, and the effective fume sucking effect is achieved.
Description
Technical field
The invention belongs to fume extractor, specifically a kind of hollow eddy current smoke evacuation system be used on air draft smoke evacuation product.
Background technology
Smoke exhaust as the equipment of kitchen discharged lampblack, by outside the oil smoke discharge chamber in kitchen during for cooking.Its version is different, has hanging structure, to be also integrated in integrated kitchen range.But existing smoke evacuation system smoking scope is less, smoking effect needs to be improved further.
Summary of the invention
The technical assignment of the technical problem to be solved in the present invention and proposition overcomes the less defect of existing smoke evacuation system smoking scope, provides a kind of hollow eddy current smoke evacuation system be used on air draft smoke evacuation product.
For achieving the above object, the hollow eddy current smoke evacuation system be used on air draft smoke evacuation product of the present invention, comprise spiral case, the centrifugal impeller be placed in spiral case, motor for driving centrifugal impeller to rotate, described spiral case has axial air inlet and tangential air outlet, it is characterized in that: described spiral case is configured with the air intake guiding channel being communicated with described air inlet, in the port of described air intake guiding channel, be provided with spiral helicine guiding flabellum.
As optimization technique means: the port of described air intake guiding channel towards consistent with the radial direction of described spiral case.
As optimization technique means: the port of described air intake guiding channel is rectangular or circular.
As optimization technique means: be provided with central passage in the port of described air intake guiding channel, described guiding flabellum is distributed between the perisporium of the port of described central passage and described air intake guiding channel.
As optimization technique means: the port of described air intake guiding channel upward.
As optimization technique means: the air outlet of described spiral case connects corrugated airduct through switching pipe fitting.
As optimization technique means: the air outlet of described spiral case connects corrugated airduct.
As optimization technique means: described guiding flabellum is fixed.
The invention has the beneficial effects as follows: by being configured with the air intake guiding channel being communicated with air inlet on spiral case, and in the port of air intake guiding channel, be provided with spiral helicine fixing guiding flabellum, flow rotation is guided to enter the port of air intake guiding channel during work, simultaneously produce eddy current in compressing mode at air inlet and drive mass air flow constantly to enter spiral case, make the overall suction of cigarette machine more powerful, smoking scope is larger, thus reaches more effective smoking effect.

Detailed description of the invention
Below in conjunction with Figure of description, the present invention will be further described.
As shown in Figure 1, the hollow eddy current smoke evacuation system be used on air draft smoke evacuation product of the present invention, comprise spiral case 01, the centrifugal impeller 02 be placed in spiral case 01, motor 03 for driving centrifugal impeller 02 to rotate, spiral case 01 has the air inlet 11 of the axis bearing of trend of motor shaft (in the figure) and the air outlet 12 of tangential (tangential direction of spiral case circular arc portion), spiral case 01 is configured with the air intake guiding channel 04 being communicated with air inlet 11, in the port 41 of air intake guiding channel, is provided with spiral helicine guiding flabellum 42.
Concrete, in order to be suitable for the downdraft lampblack absorber in integrated kitchen range, the port 41 of air intake guiding channel towards consistent with the radial direction of spiral case.The port 41 of air intake guiding channel is rectangular or circular, can also be defined as other shape according to demand.The port 41 of air intake guiding channel upward.In order to effectively guide air-flow, be provided with central passage 43 in the port 41 of air intake guiding channel, guiding flabellum 42 is distributed between the perisporium of port 41 of central passage 43 and air intake guiding channel.And the air outlet 12 of spiral case (can be illustrated as elbow bend through switching pipe fitting 05, the pipe fitting of suitable construction can be selected according to direction during concrete enforcement) connect corrugated airduct 06, or directly connect corrugated airduct, the other end of corrugated airduct is used for guiding chimney into.
When machine is started working, motor 03 drives centrifugal impeller 02 to rotate, and produces suction, make flow rotation enter the port 41 of air intake guiding channel in spiral case 01; Simultaneously produce eddy current in compressing mode at air inlet and drive mass air flow constantly to enter spiral case (chain-dotted line with arrow in figure illustrates the flow direction of air-flow), make the overall suction of cigarette machine more powerful, smoking scope is larger, thus reaches more effective smoking effect.
