Abstract

Fitted kitchen element with an edge or surface on the front, in an interior or on the working surface thereof which may be totally actively or passively illuminated.

Description

Refrigerator

The present invention relates to a kind of refrigerator with at least one Lighting Division section.

Well-known is all to illuminate the inner chamber of kitchen appliance basically fully with long light source a kind of approximate point-like or that embed, as refrigerator, top-open type refrigerator, baking box, micro-wave oven etc.Just can discern the article in the inner chamber for the user or understand their current situations with this inner chamber illumination.

Disclose a kind of device that is used for the refrigerator inner cavity illumination by patent documentation US 6 210 013 B1, in this device, light has been injected in the plate by the tubular lamp on the side arris that is arranged in plate.Plate by printing opacity or material transparent make, and have and be used for and will inject the mechanism of the light scattering of plate.Described lamp is connected with power supply by the cable that is provided with plug, and extends through the wall body of refrigerator.

Another kind is used for to the device of the inner chamber illumination of cooling apparatus open by open source literature EP 0 971186 A2.Use light emitting diode as light source at this, described light emitting diode is arranged in the lid or the recess on the sidewall of inner chamber.These recesses cover by the thin slice with light scattering or light boundling characteristic, are used for making light to be distributed in inner chamber with suitable manner.In a kind of scheme of design for scheme as an alternative, light emitting diode is arranged along the guide rail that is arranged in the glass plate in the inner chamber, thereby is imported in the glass plate by the light that light emitting diode penetrates.The energy of light emitting diode is supplied with useless going through in the document.

A kind of switching device that is used for the inner chamber illumination of refrigerator or household freezer is disclosed in open source literature DE 42 12 510 A1, in this switching device, use as the switch that is used to connect and cut off the inner chamber illumination and can respond to the switch element of adjusting, and be provided with the movable switch magnet of arranging.

Task of the present invention is to propose a kind ofly to make fundamentally improved, as to have emphasized refrigerator specific part and illumination scheme that expand designability greatly to known illumination design.

This task solves in the following manner, promptly at refrigerator with the lighting device that is used for the inner chamber illumination, this lighting device has a plurality of white light-LED and at least one diffuser of arranging adjacent to the light launch site of LED is used for the light of LED directional transmissions is assigned to big illuminated area, described diffuser is designed to the light conducting member on plane by flat, described white light-LED forms a kind of layout of straight line basically at least one arris of flat, and described white light-LED is provided with the plane that its radiation direction is parallel to flat, thereby the light of the LED that injects by arris just penetrates by at least one surface of flat, in sidewall of refrigerator or household freezer and/or door, be provided with an induction type device for transformer, be used on a plurality of precalculated positions, white light LEDs being carried out inductive power supply.

Preferably in refrigerator, or near the side arris of the inwall of an inner chamber rear wall scattered reflection, especially unglazed or intracavity sidewall or door on and/or arranged the white light-LED that is essentially straight line above and/or under the upper edge on the arris, its radiation direction becomes an acute angle with the plane of inner chamber rear wall or intracavity sidewall or door inwall, especially almost inswept, thereby all will be by the light scattering reflection of LED emission on its most surface.

In addition, can be the white light-LED of straight line being provided with basic on the arris that a large-area optical component and is positioned at this member at least on the inner chamber rear wall of refrigerator or the intracavity sidewall or on the door inwall, its radiation direction is basically parallel to the extension plane of optical component, thereby at least one section inner chamber rear wall, or on the intracavity sidewall, or make the light of injecting the LED in the optical component by edge regions to penetrate on the door inwall in large area.

Especially the optical component on plane has constituted basically or has covered whole inner chamber rear wall or intracavity sidewall or door inwall.

At least one arris of described flat is preferably inlayed with metal or plastics.

Preferably on a back arris of refrigerator, be provided with a kind of white light LEDs of straight line that is substantially in addition adjacent to the door storage frame of door inwall, its radiation direction becomes an acute angle with the plane of door inwall, especially almost inswept, therefore called the inwall scattered reflection by the light of LED emission at its most of area.

Described refrigerator can be on the front or be provided with the surface of a chromatic colour hologram in inner chamber.

With the solution of described suggestion,, improve the use value performance by " use up and guide the user " except expanding wittingly the designability for refrigerator.

In first flexible program of the present invention, be provided with a kind of arris, drawer arris or sales counter arris as the arris that illumination capability is arranged, they especially are furnished with a kind of LED (light emitting diode) device of straight line.In another kind of flexible program, be bumped into the edge regions of other bulking block floor or inner chamber as arris being provided with that illumination capability is arranged, this position especially is furnished with a kind of LCD device of straight line.Can also be provided with a kind of edge regions of handle in addition as the arris that illumination capability is arranged, it especially is furnished with the LED matrix of straight line.

Can produce the colored light (with by the known mode of other application itself) of strengthening with colored LED (light emitting diode) or long color lighting pipe, the illumination of the color neutrality on the arris of refrigerator or surface then can realize by the white light-LED of use can be provided nearby in the mode of the special saving energy.The efficient that this lighting apparatus produces luminous energy improves, and operating voltage is low, and this just can realize simple especially connection and needn't take various cooling provisions.

In Figure 1A to 1I, pointed out in cooling furniture or cooling apparatus, to realize by the solution of the present invention with a plurality of principle sketches.These diagrams and described embodiment preferred of the present invention in " refrigeration " envelop of function in a kitchen together corresponding to features that these diagrams are explained.

Here Fig. 1 F to 1I has illustrated the illumination scheme as a kind of ice maker of the specific function scope of an ice chest specially, and this refrigerator is considered all should use up to emphasize from the function profile.

Fig. 2 has represented to form the signal approach on a kind of illumination surface (for example surface of inlaying the bottom of a kind of general illumination of a refrigerator) by means of being arranged in narrow light source in the edge regions with sketch.Can use a kind of LED-device of straight line as this light source, and make the light that produces by it in a surface element with photoconduction performance, carry out " turning to " and scattering in compellent especially mode, this surface element is in principle by the display of electronic apparatus (notebook computer, mobile phone) cicada just.

Point out that clearly the present invention can also realize with a plurality of other forms of implementation except embodiment above-mentioned and simple expression in the accompanying drawings.Should emphasize in addition all to list in protection scope of the present invention with any combination of flexible program shown in the accompanying drawing.
