Wo 2008055837

The present invention relates to a kind of Wo 2008055837.It has a chimney, at least one light source and at least one and is used to guide light guide member by the light of described at least one light emitted.

For the outward appearance DE 29909279U1 that improves a Wo 2008055837 has for example described a kind of Wo 2008055837 with a shielding and a chimney, wherein, parts of the shielding and/or the wall of chimney comprise the backplate that is made of glass as structure member.The backplate that is made of glass in this Wo 2008055837 of prior art is maintained on the framework.Also can instead these backplates be arranged on a back that has the plate of decorative groove.The backplate of prior art is glass plate preferably.On this glass plate, can melt a kind of decorative pattern.In order further to improve decorative effect and to provide a kind of space illumination of damping that some electroluminescence bodies are set in chimney.

The shortcoming of this structure of Wo 2008055837 is the manufacturing costliness of chimney on the one hand.Particularly in the supporting structure that for this reason is provided with, particularly in metal framework, must use the glass backplate, and must guarantee being tightly connected between glass backplate and the supporting structure on the other hand.

In addition, EP 1217309B1 has also described a kind of Wo 2008055837 that is used for the kitchen range top.This Wo 2008055837 has one or more turnover decorative panel.In this Wo 2008055837, decorative panel is arranged on the upper surface of shielding of Wo 2008055837.Described decorative panel preferably scribbles ornament materials in one side, and can be made by glass.Though, yet for the user of Wo 2008055837, can only see this decorative panel conditionally with of the way manufacturing of specific energy simplification Wo 2008055837 mutually of above-mentioned use backplate as the structure member use.Can only improve to little degree the decorative effect of Wo 2008055837 in this respect by decorative panel.

Therefore task of the present invention provides a kind of Wo 2008055837 with improved eye impressions, and even so can also be with the plain mode manufacturing.

This task has chimney, at least one light source and at least one and is used to guide the Wo 2008055837 by the light guide member of the light of described at least one light emitted to be accomplished by a kind of according to the present invention.The advantage of this Wo 2008055837 be with this light guide member be arranged on Wo 2008055837 chimney at least one the outside on.

According to the present invention, that part of the blower-casting that is holding Wo 2008055837 of Wo 2008055837 is called chimney.This chimney this regional attaching parts that are Wo 2008055837 particularly.Chimney comprises a front and two sides in a Wo 2008055837 that should be installed on the wall.If Wo 2008055837 is that (Inselesse) is set separately on the contrary, then chimney has a front, a back side and two sides.At the lower area of chimney, a smog screen can be set under chimney perhaps.

By can being guided further by the outside of the light of light emitted-be arranged on chimney, light guide member-by this light guide member can improve the visual appearance of Wo 2008055837.Usually the outside of chimney is vertically to extend, and it can be front, side and/or the back side of chimney according to the present invention.What these surfaces of Wo 2008055837 were different with smog screen upper surface is always observable for the end user.Simplified the manufacturing of Wo 2008055837 in addition by the outside that light guide member is arranged on chimney.In Wo 2008055837 according to the present invention, set up the stability of chimney by the material in the chimney outside.Therefore this light guide member can pure viewpoint by optics design.In Wo 2008055837 according to the present invention, there is no need light guide member is carried out integrated, as it in the prior art with regard to proposition with regard to a glass plate of a scaffold.

Preferably light guide member is arranged on the material in the outside of chimney.The advantage of this design form is that the material in the outside of chimney can form a continuous surface.Do not need the hole, for example the groove in the chimney of advising as prior art.Simplified the general construction of Wo 2008055837 by this measure.Particularly the material by the chimney outside always allows the people can't see the inside of chimney in this design form of Wo 2008055837, and therefore also can't see the blower-casting that is included in wherein or other parts.In Wo 2008055837 according to the present invention, needn't on light guide member, additionally apply cover layer.This in the prior art cover layer just stops people to look toward the inside.

Preferably light guide member is abutting on the outside of chimney on its length.Even by a unified outward appearance of light guide member also can be provided under the situation that provides a kind of continuous contact surface not having illumination between the outside of chimney and the light guide member.With like that some light guide members are opposite, promptly they only partly abut on the outside of chimney and for example cover hole or groove in the outside of chimney, give a kind of unified eye impressions of people according to light guide member of the present invention in this form of implementation.In addition, in this form of implementation, also simplified light guide member fixing on the outside.For example light guide member can be pasted and be bonded on the continuous contact-making surface.Not worrying amplexiforming agent in this case penetrates in the hole or groove of chimney.

According to a form of implementation groove can be set in the outside of chimney, and light guide member is accommodated at least in part in this groove.Though this form of implementation with reference to being described when the unique groove of of the outside of chimney, also can for example be provided with a plurality of grooves on front and the side below on a plurality of outsides of chimney in scope of the present invention.

Provide an additional maintaining part by arranged outside groove for the light guide member that holds therein at chimney.Therefore reduced other jockey, for example clamped connection or bonding connection requirement.Adopt another advantage of groove to be to make light guide member always to be arranged on the position of the regulation of Wo 2008055837 reliably in the outside of chimney.Additionally be used as the positioning auxiliary device of light guide member in this respect in this form of implementation further groove.

Last this groove can have and the corresponding degree of depth of the material thickness of light guide member.Therefore light guide member can be accommodated in the groove fully in this form of implementation, and the surface in the chimney outside is smooth surface.This version particularly has superiority aspect the outside of the cleaning chimney of necessity.Yet also can make light guide member stretch out the groove in the outside of chimney according to the present invention.

According to a form of implementation light guide member is a plate, and the edge is provided with hypotenuse (Fase) respectively in this plate.Plate is in the width that a side reduces by hypotenuse can be installed to groove on the outside of chimney, and the side with bigger width of plate exceeds this groove.Can improve eye impressions further by this layout.Particularly also can exceed groove ground in the side and penetrate, and the end user can see this light by the light guide member guided ray.

Be arranged near the end in the light guide member according to a preferred form of implementation light source.Light guide member is an elongated light guide member preferably, and particularly preferably has the cross section of a rectangle.Particularly can be with a plate as light guide member.This plate can have the corresponding curvature of arc in the outside of and chimney where necessary.One of them of end of longitudinal direction along it with light guide member in this form of implementation is called the end.

By light source being arranged near one of them a kind of like this distribution that can reach light by light guide member of light guide member, this distribution has Wo 2008055837 and makes us pleasing outward appearance.The highest at source region by the luminous intensity that light guide member provides, and its luminous intensity is along with the increase of the distance of light source and reduce.Near the of one of them end that in addition light source is arranged on light guide member is being favourable aspect the infield of light source.Particularly light source can be arranged on such position, the end user of Wo 2008055837 cannot see this light source on this position.Light guide member can begin from this position to extend to desirable aspect, and can be distributed on its whole length from the light that light emitted goes out.

For example light source can be arranged in the zone of a smog screen.This smog shields in the lower area that is arranged on chimney or under chimney.This design shape has special advantage, because in the zone of smog screen live part is set, for example is used for the functional unit of the air exhauster of Wo 2008055837, perhaps the electric component of other lighting device.Therefore simple mode in this location, and realize providing desired electric current to light source by little connection length.

Have a smog screen according to a preferred form of implementation smog eliminating, and light guide member extends upward from this smog screen.This vertical orientation by light guide member can be covered by light guide member along the big as far as possible section in the outside of the chimney of Wo 2008055837.The light effect optimization that can obtain with light guide member perhaps can be utilized this light effect particularly well by this measure.Particularly in a kind of zone, can produce the light that a kind of increase of the distance along with distance smog screen dies down continuously in by a kind of light guide member of light illumination at smog screen.Therefore, can avoid making the end user dizzy by a kind of light guide member that on whole length, has uniform luminous intensity.

Particularly advantageously light guide member extends on vertical direction ground in the middle of the level in front in the front of chimney.The advantage that light guide member is arranged on the front of fume hood is that on the one hand the common end user of this one side is observable, because the functional unit of Wo 2008055837 just is arranged on the front of Wo 2008055837 usually.The functional unit that is used to operate other lighting device air exhauster or Wo 2008055837 on the other hand also is arranged on the center, just is arranged on the centre in the front of Wo 2008055837.Like this, just simply mode realizes providing the light source of light and being connected of power supply to light guide member.Also light source can be arranged in the zone of functional unit in addition, and this set end user is invisible.

Preferably paste at least in part in the outside of light guide member and chimney.This fixed form has a series of advantage.On the one hand, perhaps do not need special processing by pasting the material that can not damage light guide member, for example needed in bolt connection etc.In addition, this connection be cannot see end user's incoming call in this stickup connects.If be provided for holding at least in part the groove of light guide member on the chimney of Wo 2008055837, then this stickup connection can be light guide member provides a kind of additional maintenance.In addition, by using bonding agent can regulate the optical characteristics that is fixed on the light guide member on the Wo 2008055837 best.Particularly can be filled in the intermediate space that exists between the bottom portion of groove on light guide member and the chimney outside or the chimney outside by bonding agent, and therefore can avoid on the back side of light guide member because the refraction or the reflection of the undesirable ambient light that intermediate cavity may occur.Refraction by ambient light when light source is closed or reflection observer only can see that the back side of light guide member can't see the outside of chimney.

For the visual appearance that influences light guide member further and its photoconductive property, can on the surface in the outside of chimney, handle, particularly hacking light guide member.This surface to the outside that faces chimney of light guide member, just the advantage handled of the back side of light guide member is to guarantee opposed surface, the just cleaning easily in the front of light guide member.

In addition, by the hacking on the surface that faces the chimney outside being handled or other processing can be given better photoconduction of light guide member or scattering power.Except the back side by the processing of this light guide member the caused scattering of the material of light guide member can cause entering the back scatter of the light of light guide member at light guide member by light source, and send so forward.Like this, this illumination is for the observer of light guide member, and just the end user for Wo 2008055837 sees easily, but also dazzle-free to him.

Particularly preferably be blasting treatment is carried out on the surface that faces the chimney outside of light guide member.Handling one side by the hacking of this form evenly distributes the surface texture on the light guide member.Adopt this method that the hacking on surface or processing are carried out simply and fastly on the other hand.

Preferably light guide member is a kind of scatter plate that preferably is made of plastics.For the present invention one since its material behavior will introduce the light of glass carry out scattering and so the direction that also enters with light dish or the plate launched obliquely be called scatter plate.

Scatter plate can well continue the light that is injected into light guide member by light source guiding on the one hand.On the other hand when adopting scatter plate to penetrate, even also can guarantee the outside of the visible chimney of end user's energy when particularly light source has been closed when the side of hacking leans against on the outside of chimney.
