Abstract
The invention relates to an oven (1), especially to a domestic oven, with a cooking cavity (2), wherein means (3, 4, 5, 6) are arranged for supplying hot air to the cavity (2). To improve the cooking result the invention is characterized in that the means (3, 4, 5, 6) comprise at least two heating elements (3, 4), wherein air is ventilated along or through the heating elements (3, 4) by at least one fan (5, 6). Furthermore, the invention relates to a method for operating such an oven.
Claims11
Oven comprising a cooking cavity, wherein means are arranged for supplying hot air to the cavity from the environment, wherein the means comprise at least a first and a second heating element, wherein air is ventilated through the first and second heating elements by at least one fan and prior to entering the cooking cavity, further wherein the first and second heating elements are arranged along one common flow path which leads to the cavity so that the second heating element is arranged downstream of the first heating element, wherein the first and second heating elements are designed to be independently operable, each having a switch on position and a switch off position only, and wherein each heating element has a heating power between 1,000 W to 2,000 W, wherein the flow path is vertically arranged parallel to a sidewall of the cooking cavity, the fan is positioned along the flow path near a top portion of the oven and the first and second heating elements are positioned downstream of the at least one fan at lower elevations than the at least one fan.
Method for operating an oven comprising, a cooking cavity and mechanism for supplying hot air to the cavity, wherein air is ventilated from the environment through one common flow path which leads to the cavity, wherein the air is heated up during its passage of the flow path by at least two heating elements prior to entering the cooking cavity and wherein air is ventilated through the at least two heating elements by at least one fan, and wherein each heating element is independently operable, each having a heating power between 1,000 W and 2,000 W, wherein the flow path is vertically arranged parallel to a sidewall of the cooking cavity, the fan is positioned near a top portion of the oven and the heating elements are positioned along the flow path downstream of the at least one fan at lower elevations than the at least one fan.
Oven comprising:
- a cooking cavity;
- a first heating element positioned within a flow path, the flow path being in fluid communication with the cooking cavity, the flow path vertically arranged parallel to a sidewall of the cooking cavity;
- a second heating element positioned within the flow path and downstream of the first heating element;
- and
- at least one fan configured to supply hot air to the cooking cavity, the fan positioned near a top portion of the oven,
- wherein the first heating element and the second heating element are independently operable and positioned along the flow path downstream of the at least one fan and at lower elevations than the at least one fan,
- wherein the hot air supplied to the cooking cavity is heated by the first and second heating elements prior to entering the cooking cavity, and
- wherein each heating element has a heating power between 1,000 W and 2,000 W.
