This nozzle preferably includes air stream guiding elements, and this air stream guiding elements can be connected to the inwall of nozzle.This guiding surface is preferably limited by the outer surface of air stream guiding elements.This air stream guiding elements can limit mobile control port at least in part.In a preferred embodiment, this mobile control port is located between the internal surface of air stream guiding elements and the 3rd wall of nozzle.This of nozzle the 3rd wall is preferably the antetheca of nozzle.The antetheca of nozzle is preferably connected at least one of inner and outer wall of nozzle.
This mobile control port is preferably arranged to the second outer surface that guides air stream to cross nozzle.This of nozzle the second outer surface is preferably a part for the outer surface of the antetheca of nozzle.This second outer surface can limit the hole of nozzle at least in part, more preferably limits at least in part the front section in the hole of nozzle.This second outer surface preferably includes the second coanda surface, and this second coanda surface is located in the tight downstream of the control port that flows.This second outer surface preferably includes the second diffuser surface, and this second diffuser surface is outwards tapered with respect to the axis in hole.This second diffuser surface can be frustoconical or it and can be bending.

Air stream often depends on the shape of the final outer surface that air stream adheres to from the direction of nozzle transmitting.In the time that the Air Flow through the control port that flows is suppressed, for example, by sealing the control port or by suppressing through the Air Flow of mobile control chamber that is connected to the control port that flows of flowing, the shape of the first guiding surface is preferably arranged so that air stream is directed away from the second outer surface of nozzle, and thus away from the second guiding surface of nozzle.Therefore, when the air when suppressed through the air of control port of flowing of flowing will depend on the shape of the first guiding surface of nozzle from the direction of nozzle transmitting.
When air is when air is launched from air outlet from the control port transmitting of flowing simultaneously, will trend towards being attached to from the air of the control port transmitting of flowing and be positioned to flow second outer surface in control port downstream.Air has changed the pressure gradient across the air stream from air outlet transmitting from the transmitting of the control port that flows.For example, relatively low pressure can be based upon near a part that is positioned the tight-lipped downstream of mobile control end for the second outer surface, and thus on a side of the air stream of launching from air outlet.The pressure difference generated force across the air stream from air outlet transmitting of setting up thus, this is made every effort to promote makes air stream towards the second outer surface.This can cause the air of launching from the air of air outlet transmitting with from the control port that flows to be all attached to the second outer surface of nozzle.As mentioned above, air depends on the shape on the final surface that air stream adheres to from the direction of nozzle transmitting, so in this case, air will depend on the shape of the second guiding surface of nozzle from the direction of nozzle transmitting.

As mentioned above, this mobile control port is preferably arranged to the second outer surface that guides air stream to cross nozzle.When air is when air is launched from air outlet from the control port transmitting of flowing simultaneously, will trend towards being attached to second outer surface in the downstream that is located in the control port that flows from the air of air outlet and the transmitting of mobile control port.But, this nozzle can alternative be arranged so that, in the time that the Air Flow through the control port that flows is suppressed, be attached to the second outer surface from the air of air outlet transmitting, and in the time being allowed to through the Air Flow of the control port that flows, separate from the second outer surface from the air of air outlet transmitting.For example, mobile control port can be arranged to towards the inwardly mobile air stream of controlling of guiding of vertical plane, and for example radially inside, this vertical plane extends through axially bored line and comprises axially bored line.Control air stream from mobile control port transmitting during when flowing, the air deflection of launching from air outlet is away from the second outer surface of nozzle.Therefore,, in the time being allowed to through the Air Flow of control port of flowing, air will depend on the shape of the first guiding surface of nozzle from the direction of nozzle transmitting.
Air outlet is preferably the form of groove.This inner passage is preferably around the hole of nozzle.Preferably extend around hole at least in part this air outlet.For example, nozzle can comprise the single air outlet of extending around hole at least in part.For example, this air outlet also can be around hole.This hole can have circular cross section in the plane perpendicular to axially bored line, so that this air outlet can be is round-shaped.Alternatively, nozzle can comprise multiple air outlets, and open around the span of nozzle the plurality of air outlet.

The geometrical shape of air outlet and guiding surface can be controlled two different profiles of the air stream being produced by nozzle at least in part.For example, when when observing through axially bored line and in being located in the cross section of the plane that the cardinal principle the top and bottom of nozzle locates midway, the shape of the first guiding surface can be different from the shape of the second guiding surface.For example, in this cross section, the folded angle of axially bored line and the first guiding surface can be less than axially bored line and the folded angle of the second guiding surface.
This control means preferably has the first state and the second state, and this first state suppresses the Air Flow through the control port that flows, and this second state allows the Air Flow through the control port that flows.This control means can be the form of valve, and it comprises valve body and actuator, and this valve body is controlled the suction port of chamber for sealing to flow, and this actuator is for moving valve body with respect to entrance.Alternatively, this valve body can be arranged to the mobile control port of sealing.This valve can be can manually-operable valve, and it promotes between these two states by user, pulls or other modes are moved.In one embodiment, this actuator is driven by motor.This motor is preferably driven by control circuit or the controller of nozzle.This control circuit can be the main control circuit of fan component.Alternatively, this control circuit can be second control circuit, and this second control circuit is connected to the main control circuit of fan component.This main control circuit is preferably arranged to the signal drive motor that response receives from the user interface of fan component.This user interface can comprise that button on the body that is located in fan component or other users can actuation member, and it is actuated with drive motor by user.Alternatively, or additionally, this fan component can comprise remote control unit, and this remote control unit is the state with change control means for signal transmission instruction main control circuit drive motor.
This control chamber that flows can have suction port, and this suction port is located on the outer surface of nozzle.In this case, all air streams that received by inner passage can be launched from air outlet.But the control chamber that flows is preferably arranged to and receives the control air stream that flows from inner passage.In this case, the first portion of the air stream being received by inner passage is optionally allowed to enter the mobile chamber of controlling to form the mobile air stream of controlling, and wherein the remainder of this air stream can launch through air outlet to be combined with the control air stream that flows in downstream, air outlet again from inner passage.
This inner passage can be controlled chamber from flowing by the inwall of nozzle and separate.This wall preferably includes to flow controls the suction port of chamber.This suction port that flows control chamber is preferably positioned near the base portion of nozzle, and air stream enters nozzle through this base portion.
Flowing, it is extensible through nozzle and adjacent with inner passage to control chamber.Therefore, this control chamber that flows can extend around the hole of nozzle at least in part, and can be around this hole.
This inner passage can comprise the device of at least a portion for heating the air stream being received by nozzle.
In the third aspect, the utility model provides a kind of fan component, and this fan component comprises impeller, the motor for rotary blade with generation air stream, for the said nozzle of admission of air stream, and for controlling motor and for changing the controller of state of control means.This controller can be arranged as the speed of adjusting motor in the time that the state of control means is changed.For example, this electric machine controller can be arranged to the speed that is changed to reduce while producing concentrated air stream motor when the state of control means, and in the time that the state of control means is changed to produce the air stream of diffusion, increases the speed of motor.

First,, in the time that fan component 10 is closed in advance, the speed of being selected by main control circuit 38 arranges corresponding to the speed of previously having been selected by user.For example, if user previously selection speed arrange 7, motor 60 is with 7600rpm rotation, and numeral " 7 " is displayed on display device 30.When user selects different speed settings, present speed setting is displayed on display device 30.
Motor 60 rotary blades 56 cause main air flow to pass the suction port 52 that suction port 14 enters body 12 and advances to pipeline 50.This air stream enters the lower knuckle section of the inner passage 94 of nozzle 16 through the outer surface guiding of the shaping of pipeline 50 and the air outlet 54 by pipeline 50.In the lower knuckle section of inner passage 94, main air flow is divided into two strands of air streams, and it is advanced around the hole 80 of nozzle 16 along contrary directional ring.One in air-flow enters the straight section of the inner passage 94 of a side that is located in hole 80, but another strand of air-flow enters the straight section of the inner passage 94 on the opposite side that is located in hole 80.When this air-flow is during through the straight section of inner passage 94, per share air-flow turns over approximately 90 ° and through airflow path 128,156,178, advances towards the corresponding air outlet 18 of nozzle 16, and this airflow path 128,156,178 is limited by frame 120.
The main air flow of launching from air outlet 18 and then cross the coanda surface 190 being limited by the rear portion housing section 84 of nozzle 16, cross the diffuser surface 192 being limited by the rear portion housing section 84 of nozzle 16, and finally cross the guiding surface 206 being limited by the air guiding segments 88 of nozzle 16.When this main air flow is crossed these whens surface, so so shape that it is attached to these surfaces and profiles of main air flow and direction depend on guiding surface 206 in the time that main air flow is launched from nozzle 16.As mentioned above, in this example, so this guiding surface 206 tapers inwardly and the main air flow launched from nozzle 16 has the profile tapering inwardly towards axially bored line X equally towards the axially bored line X of nozzle 16.
Air stream causes by producing ancillary air stream from external environment condition entrapped air from the transmitting of air outlet 18.Air is sucked and enters air stream from the surrounding environment of nozzle 16 and anterior environment through the hole 80 of nozzle 16.This ancillary air stream and the air stream of launching from nozzle 16 mix, mix or total air draught to produce, or air-flow, spray forward from fan component 10.At air stream in the situation that axially bored line X tapers inwardly, the surface area of its exterior contour is relatively low, itself so cause carrying secretly and through the relatively low flow of the air in the hole 80 of nozzle 16, so the combined air flow being produced by fan component 10 has relatively low flow from the relatively low air of the front area of nozzle 16.But for the flow of the given main air flow being produced by impeller, the flow that reduces the combined air flow being produced by fan component 10 is associated with the increase of the top speed of the combined air flow standing on the fixed pan in downstream that is positioned nozzle.Direction together with air stream towards axially bored line X, this makes combined air flow be suitable for rapid cooling fan component 10 user above that is positioned at.This user can activate swing mechanism 40 by the dedicated button of depressing in remote control unit, sprays forward direction to swing combined air flow from fan component 10.
If fan component 10 is placed in the second operator scheme or some heating mode by the button that user presses in remote control unit, this remote control unit produces and transmission infrared signal, and this infrared signal comprises the data of indicating the behavior.This signal is received by the receiver 28 of user interface circuitry 26, and what it transmitted this signal receives main control circuit 38 so that fan component 10 is placed in to the second operator scheme.When in this second operator scheme, this main control circuit 38 is by the temperature T of previously having been selected by user s, with in fan component 10 or through the temperature T of the air of fan component 10 acompare this temperature T adetect and be provided to main control circuit 38 by control circuit for heater 112 by thermistor.Work as T a<T stime, these main control circuit 38 instruction control circuit for heater 112 activate heater assembly 104.
In this second operator scheme, this main control circuit 38 is selected the rotational speed of motor 60 from second value scope, and the example of this second value scope is listed below.Equally, corresponding one of the each value within the scope of second value and at user option speed setting is associated.

Normally, arrange for the most of speed that can be selected by user, low in second value scope than in the first number range of the rotational speed being associated of motor 60, to avoid producing less desirable air-flow in the local environment that will be heated by fan component 10.For example, in the time that fan component 10 is converted to the second operator scheme from the first operator scheme, if user selects speed to arrange 7, the rotational speed of motor 60 reduces to 6150rpm from 7600rpm.
As mentioned above, in the time that this air-flow passes the straight section of inner passage 94, per share air-flow is through airflow path 128,156,178 towards the corresponding air outlet 18 of nozzle 16, and this airflow path 128,156,178 is limited by frame 120.The first portion of per share air-flow is through the first airflow path 128, and the second portion of per share air-flow is through the second airflow path 156, and the Part III of per share air-flow is through the 3rd airflow path 178.In the time that heater assembly 104 is activated, the heat being produced by the heater assembly 104 being activated is transferred to the first portion of main air flow with the temperature of the first portion of rising main air flow by convection current.The second portion of this main air flow is advanced along the internal surface 98 of inner shell section 92, thereby serves as the thermodynamic barrier between relatively hot first portion and the inner shell section 92 of main air flow.The Part III of this main air flow is advanced along the internal surface 96 of external casing section 90, thereby serves as the thermodynamic barrier between relatively hot first portion and the external casing section 90 of main air flow.
The 3rd airflow path 178 is arranged to the Part III of main air flow is transported to and is located in 94Nei air outlet, inner passage 180.Once launch from air outlet 180, the Part III of this main air flow and the first portion of main air flow converge.The part of converging of this main air flow is transported to air outlet 184 between the internal surface 96 of portion's housing section 88 and the inwall 122 of heater housing outside.This air outlet 184 is arranged to guiding main air flow relatively hot converge first with Part III above the relative cold second portion of the main air flow of launching from air outlet 158, this relatively cold second portion serve as the outer surface 92 of inner shell section 90 and the relatively hot air launched from air outlet 184 between thermodynamic barrier.Therefore, most of internal surface of nozzle 16 shields from the relative hot air being produced by fan component 10 with outer surface.
When with the second operation mode, the profile of the air stream of the mixing that the profile of the air stream of the mixing being produced by fan component 10 and fan component 10 produce during with the first operation mode is substantially identical.In the time that the temperature of the air in external environment condition increases, be sucked the temperature T of the main air flow that enters fan component 10 through suction port 14 asimilarly increase.Indicate the signal of this main air flow temperature to output to control circuit for heater 112 from thermistor.Work as T arise to T son 1 DEG C, this control circuit for heater 112 makes heater assembly 104 is closed and main control circuit 38 reduces motor 60 rotational speed to 1000rpm.When the temperature of this main air flow drops to T sunder approximately 1 DEG C time, this control circuit for heater 112 restarts speed that heater assembly 104 and main control circuit 38 reply motor 60 to the speed being associated with the speed setting of current selection.
If fan component 10 is placed in the 3rd operator scheme or room heating mode by the button that user presses on remote control unit now, this remote control unit produces and transmission infrared signal, and this infrared signal comprises the data of indicating this action.This signal is received by the receiver 28 of user interface circuitry 26, and what it transmitted this signal receives main control circuit 38 fan component 10 is placed in to the 3rd operator scheme.When in this 3rd operator scheme, this main control circuit 38 is selected the rotational speed of motor 60 from third value scope, and the example of this third value scope is listed below.Equally, corresponding one of the each value within the scope of third value and at user option speed setting is associated.

Normally, for at user option most of speed setting, the rotational speed that is associated of motor 60 is the height in second value scope at third value scope ratio, to increase speed and the flow of the combined air flow being produced by fan component 10, thus and the more promptly heating of the room at promotion fan component 10 places or other positions.For example, in the time that fan component 10 is converted to the 3rd operator scheme from the second operator scheme, if user has selected speed to arrange 7, the rotational speed of motor 60 is increased to 7200rpm from 6150rpm.
In the 3rd operator scheme, these main control circuit 38 instruction control circuit for heater 112 along second direction drive motor 254 control mechanism 240 is placed in to its second state.This actuate actuator 252 with by valve body 242 along the second angle direction pivotable, valve 244 is moved away from the front surface 194 of inner shell section 92, control the suction port 236 of chamber 220 to open to flow.At control mechanism 240, at the second state in the situation that, the first portion of this air stream controls air stream through suction port 236 to form to flow from the lower knuckle section of inner passage 94, and this air stream is controlled chamber 220 through flowing.The second portion of this air stream is maintained in inner passage 94, and wherein, as mentioned above, it is divided into two strands of air-flows, and these two strands of air-flows are advanced in opposite direction around the hole 80 of nozzle 16.The ratio of the air stream that entering flows controls chamber 220 preferably in from 5 to 30% scope, and is approximately 20% in this example.
Control in chamber 220 mobile, this control air stream that flows is divided into two strands of air streams, and these two strands of air-flows are similarly advanced around the hole 80 of nozzle 16 along contrary directional ring.As in inner passage 94, corresponding and the upper bend section transport of upwards controlling chamber 220 along Vertical direction substantially towards flowing that these air-flows per share enters two straight section controlling chamber 220 of flowing is through each of these sections.In the time that these air-flows are controlled the straight section of chamber 220 through flowing, air is launched from the control port 226 that flows.From flowing the mobile control air stream launched of control port 226 and then cross the coanda surface 232 being limited by the front shell section 86 of nozzle 16, and cross the diffuser surface 234 being limited by the front shell section 86 of nozzle 16.
In the time that the control air stream that flows is crossed these surfaces, it is attached to these surfaces 232,234 to produce relatively low air pressure near the end of the front section 204 in air stream guiding segments 88.The pressure reduction on each (its each exterior guiding surface 206 being limited by the front section 204 of air stream guiding surface 88 of crossing) of the air-flow that this and then generation are launched across the air outlet 18 from nozzle 16.This pressure difference generated force of setting up across air-flow thus, this is made every effort to promote makes the outer surface 228 of air-flow towards front shell section 86, and it causes the outer surface 228 of air-flow contact front shell section 86 and is combined again to form main air flow with the control air stream that flows.
As mentioned above, the diffuser of front shell section 86 surface 234 is taperedly away from the axially bored line X of nozzle 16, so air stream is launched from nozzle 16 away from the profile of axially bored line X with outwards tapered.Now outwards tapered away from axially bored line X in the situation that at air stream, the surface area of its exterior contour is relatively large, itself so cause carrying secretly from the relatively high air of nozzle 16 front regions, so for the given air mass flow being produced by impeller, the combined air flow being produced by fan component 10 has relatively high flow.Therefore, control mechanism 240 being placed in to its second state has fan component 10 and produces the result of relatively wide heated Air Flow through room or office.
If subsequently user select fan mode or some heating mode, these main control circuit 38 instruction control circuit for heater 112 along first direction drive motor 254 control mechanism 240 is turned back to its first state.This activates actuator 252 so that valve body 242 is controlled to the suction port 236 of chamber 220 towards the front surface 194 of inner shell section 92 to seal to flow so that valve 244 is moved along the first angle direction pivotable.Because the air passageways of controlling chamber 220 through flowing is suppressed by mobile control mechanism 240 now, be removed across the pressure difference of the air-flow of launching from air outlet 18.This causes air-flow to separate from the outer surface 228 of front shell section 86, and by the profile of the main air flow of launching from nozzle 16 be returned to taper inwardly towards that of axially bored line X.
In a word, for the nozzle of fan component comprise suction port, air outlet, for air is transported to inner passage, the annular inner wall of air outlet and the outer wall extending around inwall from suction port.This inner passage is located between inner and outer wall.This inwall limiting hole at least in part, is aspirated through this hole by the air of launching from air outlet from the air of nozzle outside.Air outlet is arranged to the outer surface that guides air to cross nozzle.Mobile control port is located in this surperficial downstream.The control chamber that flows is provided for air is transported to mobile control port.Control mechanism optionally makes Air Flow pass mobile control port to turn to from the air stream of air outlet transmitting.
