Abstract

The utility model relates to an air-curtain fume extractor which comprises a fresh air machine case 3, a sleeve pipe 6, a fume collecting cover 2, an exhaust blower 5, a flow aid 4, etc., and the utility model belongs to the technical field of a kitchen and a toilet. Due to the disturbance of fume diffusion and lateral airflows, the present cooker hood has low extracting rate. The utility model uses a fresh air curtain as a fence so that fume only ascends and enters the exhaust blower in the fume collecting cover to be extracted, and meanwhile, fresh air continuously exchanges indoor dirty air. The air-curtain fume extractor is mainly characterized in that the air curtain is used for blocking the fume and exchanging air. The air-curtain fume extractor is used for extracting the fume for the kitchen so as to improve the kitchen environment.

Description

The wind curtain type range hood

The utility model is a kind of range hood, and it relates to a kind of wind curtain type range hood of making fence with air curtain.

This wind curtain type range hood is to be used for the kitchen to get rid of oil smoke and ventilation, belongs to kitchen guarding's technical field.

In existing range hood technology, normally form by oil-collecting petticoat pipe, exhaust blower, pipeline, light fixture and controller etc.No matter the range hood that existing market is sold be homemade or import, and its basic structure is similar.Though this class range hood is commonly used, its clean absorption rate is low, and the serious problem of kitchen pollution is well-known.The dark bell-type range hood of Chu Xianing in recent years, promptly the oil-collecting petticoat pipe is done very deeply, and slim opposite with original development its objective is in order to improve clean absorption rate.But the degree of depth of dark cover can not extend to the table top of kitchen range, at least the attraction apart from the dark bell-type range hood lower edge of 0.8 meter of table top is very low, when rising under thermodynamic activity, oil smoke follow diffusion also to be subjected to the influence of side direction wind disturbance simultaneously, so its clean absorption rate to oil smoke is still undesirable, influences its use to a certain extent.

The purpose of this utility model is to overcome the deficiency of existing technology, provides the new wind air curtain of a kind of usefulness to make fence, the wind curtain type range hood of displacement air in kitchen.

The purpose of this utility model is achieved like this: it comprises new air box 3, sleeve pipe 6, oil-collecting petticoat pipe 2, exhaust blower 5, helps stream machine 4 etc.New air box generally is located at the fresh place of outdoor air, and new wind inlet enters air blast from new air box bottom through filter, and one on top is provided with casing joint, and the other end is the pipe port of export in the oil transportation cigarette.Sleeve pipe is two multiple tubes that the caliber difference is nested together, and the interlayer between two pipes is by new wind, and the cover interface tube that it passes through on building enclosure and the indoor oil-collecting petticoat pipe joins, and imports new wind and interior pipe and gets rid of oil smoke.The oil-collecting petticoat pipe is contained in about 0.8 meter, kitchen range top, the inlet of exhaust blower is located at down in the middle of the funnel shaped inner cover, the space of making up between shell and the inner cover is as air chamber and peripheral bar shaped nozzle (does not establish on the one side by wall), after the air door of new wind before being located at the bar shaped nozzle regulated, penetrate formation air curtain fence from the bar shaped nozzle.What be located at oil-collecting petticoat pipe below helps the stream machine to the de-oiling just of part oil smoke and quicken to send into exhaust blower and discharge outdoor by pipe in the sleeve pipe.

The utlity model has following advantage: 1. the diffusion of oil smoke is subjected to the air curtain fence, makes its route by design rise to exhaust blower and discharges, so the clean absorption rate height; 2. resh air requirement can be replaced air in kitchen continuously by the standard ventilation volume, so improved the air ambient in kitchen, has eliminated the heavily contaminated in kitchen.

Further set forth the concrete enforcement of utility model technical scheme below in conjunction with accompanying drawing.

Fig. 1 is a kind of structural representation of the present utility model;

Fig. 2 is a kind of oil-collecting petticoat pipe structural representation of the present utility model;

Fig. 3 is a kind of new air box structural representation of the present utility model;

Fig. 4 is a kind of stream machine schematic diagram that helps of the present utility model.

See that Fig. 1 the utility model comprises new air box 3, sleeve pipe 6, oil-collecting petticoat pipe 2, exhaust blower 5, helps stream machine 4, controller and light fixture etc. (among the figure without drawing).New air box (see figure 3) is located at the fresh place of air, and the cabinet bottom is new wind inlet, and filter 7 is established in new wind porch in the cabinet, and cfentrifugal blower 8 is housed on it.Cabinet top is provided with the interior pipe extension 10 of cover interface tube 9 and sleeve pipe, and pipe end is equipped with anti-down draught device 11.Filtered new wind leads to the air chamber 12 in the oil-collecting petticoat pipe (Fig. 2) from sleeve pipe 6 interlayers, enter bar shaped nozzle 14 and penetrate formation air curtain fence 15 after air door 13 is regulated.16 is the air door regulating handle, and 17 is the air port, and 18 is housing, and 19 are the cover interface tube, and 20 is inner cover (referring to Fig. 4).The part oil smoke is discharged outdoor through helping the de-oiling just of stream machine and quickening to send to exhaust blower through axial flow blower 21 from the interior pipe of sleeve pipe.22 for helping the stream engine housing among the figure, and 23 is catchment cup, and 24 is motor.Help stream engine housing 22 to be connected with helping the dynamo-electric source of stream spool, the upper end of power wire pipe is connected the oil-collecting petticoat pipe helps the stream machine by conduct on the frame of wall support.Help the power line of stream machine to pass this pipe, its switch and range hood switch are set together centralized Control.

The applicant thinks that best implementation is that to seek two families at home more suitable, the factory or the company that certain marketing service ability and light sheet products working ability are arranged and be willing to compete in this field, certain professional unit is better, test-manufactures this product of trial sale marketing situation on market.If win the market, next step just can clearly show so.On manufacturing technology, there is not any difficult problem as for this product.
