Background technique

Many ceiling fans are known.The standard ceiling fan comprises one group of blade installing around first axle and the actuator of also installing around this first axle that is used to rotate this group blade.The ceiling fan of another type produces one downward air-flow to the room.For example, GB 2,049, and 161 have described a kind of ceiling fan, have the motor driven impeller of dome shaped supporting element that dangles from ceiling board and the internal surface that is connected to supporting element.Transmitted through the substantial cylindrical main body that comprises one group of air flue from the air-flow of impeller emission, to produce from the linear flow of ceiling fan emission.

Summary of the invention

The present invention provides a kind of ceiling fan, comprising:

Ring nozzle; Comprise inwall, around outer wall, suction port, at least one air outlet that this inwall extends with between inner and outer wall, be used to transmit the inner passage of air-flow to said at least one air outlet; This inner wall limit hole, the air outer from nozzle passed through this hole by the air-flow suction from said at least one air outlet emission; With

Supporting component is used to support this nozzle in ceiling board;

Wherein nozzle can be with respect to supporting component around spin axis rotation between first orientation and second orientation, and along this first orientation, air-flow is directed leaving ceiling board, and along this second orientation, air-flow is guided towards ceiling board.

Carry the air of nozzle secretly from the air-flow of ring nozzle emission, it thus serves as air the amplifier air-flow of supplying emission and the air of carrying secretly to the user.This air of carrying secretly is called as secondary streams here.Secondary streams is by room space, external environment condition or zone suction from nozzle.The air-flow of emission combines this secondary streams of carrying secretly to form air-flow combination or overall that throws forward from nozzle.The part of secondary streams is drawn through the hole of nozzle, and other parts of secondary streams in the outer periphery of the outer wall of nozzle with anterior through to combine with the air-flow of the emission in downstream, hole.

Inwall is preferably annular shape to extend around the hole and to limit this hole.The inner passage and is more preferably limited inner and outer wall preferably between inner and outer wall at least in part.Nozzle comprises that at least one suction port is used to receive air-flow.Outer wall preferably limits suction port (one or more).For example, this or each suction port can be the form that is formed on the hole in the outer wall.Nozzle comprises at least one air outlet that is used to launch air-flow.This at least one air outlet preferably is located in the section of giving vent to anger of extending between the inner and outer wall.The section of giving vent to anger can be the independent parts that are connected between the inner and outer wall.Alternatively, at least a portion of the section of giving vent to anger can with inner and outer wall in one be one.The section of giving vent to anger preferably forms at least a portion of the end wall of nozzle.As in the section of giving vent to anger, forming substituting of air outlet (one or more), air outlet (one or more) can one in the section of giving vent to anger and inner and outer wall between.The suction port of nozzle (one or more) preferably is approximately perpendicular to the air outlet (one or more) of nozzle.

The section of giving vent to anger preferably is configured to launch air-flow and leaves axially bored line, is preferably the shape of outward-dipping taper.We have found that the emission along the direction of extending away from axially bored line can increase degree that air-flow that secondary streams launched carries secretly and the flow rate (flow rate) that increases the combined airflow that is produced by fan thus to air-flow from nozzle.Here the absolute or relative value of the flow rate of the combined airflow of indication, or top speed is meant those values in three times of recorded at distances of the diameter of the air outlet of nozzle.

Do not expect to receive the constraint of any theory, we think that degree that secondary streams carried secretly can be relevant with the size from the surface area of the external frame of the air-flow of nozzle emission.When the air-flow of launching was outward-dipping or expands, the surface area of external frame was relatively large, had promoted the air-flow of emission and the Air mixing of nozzle, and had increased the flow rate of combined airflow thus.Increase is had the effect of the top speed of reduction combined airflow by the flow rate of the combined airflow of nozzle generation.This can make nozzle be applicable to the fan that produces the air-flow that passes room or office.
