Problems solved by technology

[0004] The lifetime of conventional light sources is limited due to relatively high operating temperatures during baking and due to vibrations originating from heating and air circulation mechanisms
As a result, the previously mentioned light sources have to be replaced frequently, which is time and cost intensive
[0005] In addition, many conventional oven luminaires provide only relatively dim lighting, which is often limited to the relatively small volume of the muffle or baking chamber.

Embodiment Construction

[0033] figure 1 A chamber 1 of a baking oven for domestic appliances is shown schematically. The muffle body 1 has side walls, a top wall and a rear wall defining a baking chamber 2 . The muzzle 1 has a front opening 3 for placing food to be baked (not shown) in and out of the baking chamber 2 .

[0034] Typically, a door (not shown) is provided for tightly closing the front opening 3 during baking. Normally, the door has a transparent glass portion. This glass portion is used for visual inspection and control by the user of the food product placed in the chamber 1 . This inspection is preferably performed without opening the door.

[0035] Since the muffle 1 of a baking oven is normally dark when the door is closed and viewed from the outside, the oven illuminators 4 for illuminating the inside of the muffle 1 are used to allow visual inspection during the baking process. The furnace lighting 4 is placed in a recess provided in the side wall of the muffle 1 . The positi...

Abstract

The invention in particular relates to an oven illumination (4) for illuminating the interior of a muffle (1) of an oven. Inter alia for improving lifetimes of light sources (6) of the oven illumination (4), a glass lens (7) arranged downstream the at least one light source (6) is provided. The glass lens (7) comprises a cavity (8) at least reducing heat conduction towards the at least one light source (6).

Description

technical field [0001] In particular the invention relates to an oven luminaire and an oven comprising such an oven illuminator. Background technique [0002] Ovens, especially baking ovens for domestic use, are usually provided with illuminators for illuminating the inner space of the muffle (ie the baking chamber). Such illuminators are provided primarily for the purpose of easy visual inspection and control of the baking process by the user. [0003] US4,853,508 and DE3803717 exemplarily show oven luminaires comprising incandescent lamps or halogen lamps as light sources. The furnace illuminator has a glass pane, glass cover or shield that isolates and shields the light source from the interior of the muffle. Such shielding is necessary due to the fact that a high temperature and a steamy and dusty atmosphere prevails in the baking chamber during baking of food products. [0004] The lifetime of conventional light sources is limited due to relatively high operating tem...
