Description

The on-bladed fan
Technical field
The utility model relates to fan component, relates in particular to a kind of on-bladed fan that is used for producing in indoor environment air-flow and increase circulation of air flow.
Background technique
The conventional domestic fan generally includes a rotatingshaft, drives this blade or wheel rotation to produce the driving arrangement of air-flow around a cover blade or an impeller and being used to of this rotation.Flowing and circulation formation wind of air-flow, heat energy can obtain distributing consequently by cross-ventilation, and the user can experience nice and cool.The shortcoming of this conventional domestic fan is can not be experienced uniformly by the user by the blade of rotation or the air-flow of impeller generation, thereby the user can produce by the sensation of " beating " because of experiencing disorderly air-flow; Simultaneously, the blade occupation area is bigger, can reduce ambient brightness.
Existing a kind of on-bladed fan, it comprises the ring nozzle that the base portion that is used to form air-flow and support are located at this base portion, ring nozzle limits an opening, and nozzle comprises the mouth of inner passage and ejection air-flow, base portion comprises air inlet and the impeller of being located at its shell, and the discharge portion of impeller and the inner passage of nozzle are communicated with pipeline in the base portion respectively.Impeller passes through the air inlet extracting gases, the pipeline in the base portion of flowing through and the inner passage of nozzle, and the mouth by nozzle sprays air-flow (main air-flow) again; Entrainment its ambient air from the air-flow (main air-flow) of the mouth of nozzle ejection and entrainment air-flow (secondary airflow), entrainment air-flow mainly through opening that nozzle limited with formation.The air-flow that mouth sprayed of nozzle combines and forms the total air flow of launching forward from the opening that nozzle limited with entrainmenting air-flow, and this total air flow has approximate average velocity distributions in the diameter range of nozzle.Compare with the conventional domestic fan, existing on-bladed fan has lower turbulent flow to the air-flow that the user carries, and the user can experience uniform airflow more.As everyone knows, have a large amount of suspended dust particles in the air, dust have household electric appliance killer's title, and their existence greatly influences the performance of household electric appliance.The particulate matter that suspends in the air is made up of solid or liquid particle.Airborne particulates comprises the polydisperse aerosol of solid particle and liquid particulate.The air inlet of existing on-bladed fan is not provided with air filter; after using for a long time; airborne dust can stick to the mouth of pipeline, inner passage and nozzle in impeller, the base portion; especially its internal structure complexity due to the blade wheel structure; be difficult to take apart cleaning; if no air filter will adhere to too much dust, the motor load of impeller is increased, shorten its working life and increase energy consumption.Simultaneously, too much dust can cause the finedraw of nozzle mouth blocked, makes nozzle can not spray air-flow, thereby has shortened the working life of fan.
Simultaneously, exist in the air as harmful organic substance such as formaldehyde, methylamine, benzene, dimethylbenzene and pollutant, foul smell, bacterium etc., have the on-bladed fan now and do not have deodorizing and air-cleaning function.
In summary, existing on-bladed fan obviously exists inconvenience and defective on reality is used, so be necessary to be improved.
