Description

Comprise that one can change the hair dryer of the device of air flow geometry

Technical field

[01] the present invention relates to a kind of electrical equipment that makes hair drying and/or moulding, particularly a kind of hair dryer that the air stream of shape-variable is provided.

Background technology

[02] hair dryer that uses of private or specialty generally comprises a shell, and shell has one handle, and is equipped with and makes air mobile parts and the parts that make the air heat that blows out between the outlet of the inlet aperture plate of shell and shell.The air mobile parts comprises one by the fan of electric notor drive, and heater block comprises the resistance that is arranged in air stream.The problem that this electrical equipment usually proposes is the intensity and the shape of the air stream that can change to come out from electrical equipment, so that adapt to different application, particularly realizes the hair style of different-style.

[03] in order to address this problem, some hair dryer uses one or more removable attachment, and these annexes are installed in the air outlet slit end of electrical equipment, and therefore the shape of the air stream of same quantity can be arranged.Such shortcoming is, when using this electrical equipment, must change a plurality of annexes, and during near operation is positioned at heater annex, this becomes pretty troublesome.Another shortcoming is the quantity of annex of being multiplied, and can produce the placement problem of volume heaviness and electrical equipment and its instrument like this, again the shape and the intensity of air stream is proposed some restrictions simultaneously.

[04] in addition, people understand some hair dryers, the hair dryer of describing among file US 4 232 454, US 4 977306 or the FR 2 530 132 particularly, and each hair dryer uses a pair of rotation valve that is arranged in the air outflow port pipe of electric appliance casing.Can handle these valve simultaneously by an adjusting knob that is positioned at electrical equipment pipeline outside, so that the cross section of either large or small ground limit air stream efferent duct.Therefore can the more concentrated air stream output cross section of an air stream output section transitions to of disperseing.But the startup of button is still not very comfortable, and simultaneously because the size and the position on shell of Action Button are more or less hidden, the action button is difficult to handle.Particularly, after valve is positioned at a catch net, make consequently to be difficult to make the direction of hair dryer to point to processed Tou Fa Dreadlocks in the position that is difficult to see from the outside relative another (close valve or the valve that leaves).

[05] among the file FR 2 640 857 that runs after fame with the applicant method to these problems has been proposed, the hair dryer of describing in the file comprises that one is rotated the deformable outlet nozzle assembly that control loop drives, and the diameter of rotation control loop is identical with the diameter of the air stream efferent duct of shell.Particularly, when making the control loop rotation, the interior inclined-plane of control loop moves, and two chutes are moved, these two chutes drive the rotational motion of two hinged frameworks to the outside of efferent duct in they move, so that the flexible pipe body by the nozzle of these frame supported is out of shape.This assembly forms the modular construction complexity of deformable nozzle than the easier operation of the electrical equipment of front, and this makes it use difficulty, and relatively more expensive.

[06] in the file FR 2 817 450 that runs after fame with applicant's name equally, other method is proposed, a kind of hair dryer that has the device of changing changing air stream output cross section has been described in this document, this device comprises that can be an axially movable tubular core delivery nozzle and some are positioned at the rotation valve of nozzle both sides in the air stream that is blown by electrical equipment.The rotational motion of the axial sliding movement of central nozzle and side direction valve is subjected to the control of outward turning change that is arranged in the air efferent duct extended line of shell.Make the outer shroud rotation, the interior inclined-plane of outer shroud moves axially nozzle body, has the longitudinal fluting of some inclinations on the inwall of nozzle body.Each longitudinal fluting will with the protruding pin embedding mutually of a valve, the axially-movable of nozzle body causes valve to rotate.Meet the same easy manipulation of device of this document, but shortcoming is to comprise many complex-shaped and component parts that size is little with previously described device, very fragile during these parts operations, make expensive simultaneously.

[07] in addition, recognize a kind of device of regulating the outlet of the air stream that hair dryer blows out from file WO 02/21967, this device comprises a plurality of overlapping circle segments, and these circle segments are driven around an axis rotation capable with the air levelling by a rotation outer shroud.The reason that this device that a plurality of overlay segments are arranged repeats to seal when being to use is particularly when from the open or position closed during to the another location transition, because the hair that becomes interlayer is between the different sections of device.

Summary of the invention

[08] the objective of the invention is to overcome above-mentioned shortcoming, and a kind of hair dryer proposed, this hair dryer has the cross section continually varying device that makes the air stream that is blown out by hair dryer, this device is handled easily, so that it is carry out the transition to a unidirectional concentrated air stream from a multidirectional diffused air stream, and opposite by the device that uses reliable, compact, a solid and designs simplification.

[09] another object of the present invention is a kind of hair dryer, and this hair dryer has a device that can change the geometry of the air stream that hair dryer blows out, the shape that can observe the cross section of such change again simultaneously.

[10] another object of the present invention is a kind of hair dryer, and this hair dryer has a device that can change the geometry of the air stream that hair dryer blows out, this device operation effectively, reliable, and carry out industrial production with lower manufacturing cost easily.

[11] reach these purposes by a kind of hair dryer, this hair dryer comprises and is used to heat and makes air stream mobile parts between the arrival end of a shell and a port of export, and the device that can change the geometry of the air stream that the port of export sends, this device comprises a rotation control part, so that drive at least one rotation valve motion of described device, it is characterized in that, when described part rotatablely moved around the longitudinal axis of air stream, described valve was directly driven around the axis rotation of an or inclination vertical with air stream by described part.

[12] device that can change the geometry of air stream comprises at least one rotation valve that can move between one first extreme position and one second extreme position, in primary importance, rotating valve makes the air that comes out from hair dryer flow the whole cross section of almost passing the hair dryer end, in the second place, rotate the output cross section of partially enclosed at least this air stream of valve.

[13] according to the present invention, the rotation control part by making device is able to the variation of air stream shape around the longitudinal axis rotation of air stream, so the setting of part is to rotate valve in order directly to drive, and does not have centre part.Therefore, can directly drive the valve rotation and rotate by cooperating with an adjacent movement device, for example this action component is the spiral coil of a cam, a screw, or any other can be directly converts the control part make-up piece of valve around the motion of the axis rotation of an or inclination vertical with air stream to around the rotation of the air stream longitudinal axis; Perhaps, the control part comprises the spiral coil etc. of a cam or screw, when it is driven axis rotation around air stream, valve is rotated, and contact with the end of valve.It is also conceivable that a modification, wherein rotation control part be a magnetic rings (have at least one be inserted in two other by a kind of nonmagnetic substance form fan-shaped between magnetic fan-shaped), when this magnetic rings centers on the axis rotation of air stream, this magnetic rings cooperates (for example this valve is made by a kind of ferromagnetic material) with an end of valve, this magnetic rings attracts valve, valve can be rotated, a spring can also be set, so that after magnetic attraction stops, valve brought back to its initial position.The diameter of this rotation control part equals the diameter of the hair dryer port of export at least, is convenient to handle so that guarantee the user.Therefore valve is driven under the effect of control part around an axis vertical with air stream or that tilt and is rotated (people understand the cylindricality of relative formation air stream, and the longitudinal axis of this cylindricality is arranged in the extended line of housing axis).

Therefore [14] obtain the continuous variation of air stream or air spray configuration, then the opening that forms between can the wall according to the end of valve front end and device wall or a make-up piece of the shape of air stream carries out the transition to the air-flow of an ellipse or rectangle from the air-flow of a circle, the perhaps air-flow of circular sector, this part cooperates with valve in the device.By position that changes valve and the geometry that therefore changes air stream, just can change the intensity and the speed of air stream, so that adapt to required forming operation in mode continuous or that be interrupted, and these devices with a designs simplification carry out, this device comprises that one directly acts on the control part on the valve, particularly this part is operated easily, therefore use its people to hold the hair dryer that points to hair with one, change the intensity of air stream with the another hand, leicht fallen D/A, and do not need from watching hair dryer nearby attentively.

[15] described rotation valve preferably includes a protruding pin that cooperates with a cam.

[16] this mechanism rotatablely moving of control part of device that can will change the geometry of air stream with the part (as a protruding pin that cooperates with the boss of a cam) of some designs simplifications is converted into the rotational motion of valve.

[17] in addition, described protruding pin is arranged in one and cooperates with the cam road (chemin de came) on the plane of the axis normal of air stream with one.

[18] in a modification, this protruding pin can comprise a forked end (being preferably V-arrangement), and this forked end is followed the rib in a formation cam road, perhaps, in another modification, comprises an end of swelling a little, and the groove in a formation cam road is followed in this end.Second modification preferably is because extraordinary guiding between the flank of this cam road valve protruding pin when guaranteeing the spinning movement of control part.For protruding pin and it and one of the valve coupling part less mechanical stimulus, thisly be arranged in one and directly protruding pin rotatablely move (or cam rotatablely moving relative to protruding pin) relative to the cam road be converted to rotating of valve with guiding channel that air flows vertical plane.

[19] the hair dryer port of export that is preferably in it comprises that one has the aperture plate in described cam road.

[20] therefore, the aperture plate of hair dryer has two functions: the firstth, and protection is positioned at the live part of electrical equipment, and the secondth, the part that the control valve rotates is because it has also formed the cam road.Can reduce the part number of the electrical equipment that has an air flow geometry modifier like this, therefore simplify the structure of electrical equipment.

[21] in addition, described cam road has the profile of sealing, and is positioned at the periphery of aperture plate.

[22] the cam road is positioned at the aperture plate periphery, and centers on the center symmetry of aperture plate, therefore is symmetrical in the center in electrical equipment air outlet slit cross section.This be arranged in the cam road that the air outflow port cross section has closed outline can be in the rotation of two direction of rotation, clockwise or trigonometry direction, the part that has this cam road is formed easily, and more solid, and this part is the outlet aperture plate in this case.

[23] described cam road is preferably between two adjacent ribs of described aperture plate and forms.

[24] can simplify the structure of aperture plate so more, between these two ribs spacing dimension determine make can be when protruding pin or aperture plate move the guiding protruding pin.

[25] described cam road is preferably oval.

[26] imagine that certainly one has four leaf closed outlines and (is shaped as square, its limit is a curve, and the angle is circular) the cam road, perhaps be flower shape, multiple-blade shape profile, wherein each blade sign is equivalent to the extreme position that valve is closed, blade is the closer to, the rotating distance that valve is rotated short more (for example to one or four leaf roads rotation, 1/8th circles).But oval cam road preferably because its not only easier realization, and can make valve rotate 1/4th circles when the control part of device is done bigger rotatablely moving, and is held in the hand so that will install better.

[27] preferably, described control device comprises a tubular bodies, and this tubular bodies is positioned at the air outlet slit end of described shell and supports described valve rotationally.

[28] thus air flow geometry modifier be set to tubular bodies so that is connected, and form the nozzle or the diffuser of hair dryer with the end that blows out of electrical equipment, then valve can rotate in this tubular bodies of installing, so that change the shape of its outlet.This tubular bodies of device can permanent with the port of export of hair dryer shell or removably be connected.But preferably a device that is fixed on the hair dryer shell so that therefore obtain a compactness and hair dryer that can be used as air diffusion or concentrator use, and does not need annex non-dismountablely.

[29] in addition, described tubular bodies forms the control part of described device.

[30] therefore,, drive valve, therefore drive their protruding pin along the cam road of aperture plate by the tubular bodies rotation that makes device according to this embodiment.

[31] in another embodiment, can consider to drive the aperture plate rotation, then valve and device body are fixed.In another modification, can use a different rotating ring, then this endless belt has the cam road, perhaps is used to drive the aperture plate rotation, and the cam road forms on aperture plate.

[32] described device preferably includes at least two rotation valve with the plane symmetry that comprises air stream axis.

[33] therefore, valve along the symmetrical plane of the longitudinal axis that comprises device, and therefore be the plane of symmetry of air stream when rotating mutually, rotate valve (two, four etc.) with such symmetry and can make air flow the center that concentrates on device better.

[34] in addition, described tubular bodies comprises two inwalls that form a central nozzle in its mid-plane both sides.

[35] this central nozzle can cooperate with two rotation valve that are positioned at the nozzle both sides, guides the air stream of concentrating the center of device into better, simultaneously the front end of the relative nozzle of valve is retreated, and the front end of nozzle preferably aligns with the front end of device body.

[36] flank of described inwall preferably has the opening that is sealed by described valve.

[37] can when valve is open, pass these opening diffused airs like this, particularly air be guided into the outside, these valve are abutted on the edge of opening in their closed position by the shape of valve.The device of this change air flow geometry is very compact, forms with economic material simultaneously, so that reduce cost.

bottom

16,17 that they contract backward respectively in tubular bodies 9, and their periphery is joined herein, so that form an oval central nozzle 20.In the upper wall 14 of device 7 tubular bodies 9, form an opening 18, in lower wall 15, form a similar opening 19.

[51] device 7 tubular bodies 9 has two and rotates valve, valve 23 and valve 24 once on one.For this reason, each

valve

23,24 comprises two cylindricality hinges 25 ' and 26 ', the tenon 25 that they form around the tubular bodies 9 with device 7 " and 26 " rotate.The axle of cylindricality hinge 25 ' forms a turning cylinder 25, and it is parallel to each other that the axle of hinge 26 ' forms a turning cylinder 26, two

turning cylinders

25,26, and the air stream that blows out with hair dryer is vertical.The shape and size of each

valve

23,24 are corresponding with the shape and size of the

opening

18,19 of the

inwall

14,15 of the tubular bodies 9 of device.

[52] according to the present invention, each

valve

23,24 comprises a

protruding pin

28 and 29 respectively in its inner, and when control part 8 centered on the longitudinal axis rotation of shell 1, protruding

28 and 29 is driven in a guiding channel 30 to slide.In an example shown, control part 8 is equivalent to the tubular bodies 9 of device 7.In the example in the accompanying drawings, cam road 30 forms between two
