Cooking device
First Claim
1. A cooking device including a muffle bounding a cooking space, the cooking space accessible through a muffle opening, a substantially linear door driven by a drive unit for opening and closing the door to open and close the muffle opening, the door including a surface facing the cooking space opposite of a front face of a muffle frame surrounding the muffle opening, comprising:
- an anti-trapping device which detects an object outside of said muffle opening between said door surface and said front face of said muffle frame; and
said anti-trapping device preventing trapping of said detected object by controlling said drive device, said anti-trapping device including an anti-trapping switch arranged on said front face of said muffle frame for providing signals to said anti-trapping device and said anti-trapping switch formed on said muffle frame around a substantial portion of said muffle opening accessible to an operator of said cooking device.

Abstract
A cooking device with a muffle bounding a cooking space, a linear door for closing a muffle opening and a drive device for moving the linear door to open or close the cooking space. In order to increase the operational reliability the cooking device has an anti-trapping device which detects an object outside the muffle opening between the inside of the linear door and a front face of the muffle frame. The anti-trapping device prevents trapping of the object between the linear door and the front face of the muffle frame when the object is detected.

5. A cooking device including a muffle bounding a cooking space, the cooking space accessible through a muffle opening, a substantially linear door driven by a drive unit for opening and closing the door to open and close the muffle opening, the door including a surface facing the cooking space opposite of a front face of a muffle frame surrounding the muffle opening, comprising:
-
an anti-trapping device which detects an object outside of said muffle opening between said door surface and said front face of said muffle frame; and
said anti-trapping device preventing trapping of said detected object by controlling said drive device, said anti-trapping device including an anti-trapping switch arranged on said front face of said muffle frame for providing signals to said anti-trapping device, said anti-trapping switch formed from a plurality of independent switch elements, said elements independently of one another providing signals to said anti-trapping device when pressure is exerted on one or more of the switches and said anti-trapping device detecting a time lag between said switch element signals to determine if said door is in the closed position or if a trapped object has been detected.

6. A cooking device including a muffle bounding a cooking space, the cooking space accessible through a muffle opening, a substantially linear door driven by a drive unit for opening and closing the door to open and close the muffle opening, the door including a surface facing the cooking space opposite of a front face of a muffle frame surrounding the muffle opening, comprising:
-
an anti-trapping device which detects an object outside of said muffle opening between said door surface and said front face of said muffle frame; and
said anti-trapping device preventing trapping of said detected object by controlling said drive device, said anti-trapping device including an anti-trapping switch arranged on said front face of said muffle frame for providing signals to said anti-trapping device and said anti-trapping switch forming a substantial portion of a peripheral edge of said muffle opening. - View Dependent Claims (7)

8. A cooking device including a muffle bounding a cooking space, the cooking space accessible through a muffle opening, a substantially linear door driven by a drive unit for opening and closing the door to open and close the muffle opening, the door including a surface facing the cooking space opposite of a front face of a muffle frame surrounding the muffle opening, comprising:
-
an anti-trapping device which detects an object outside of said muffle opening between said door surface and said front face of said muffle frame; and
said anti-trapping device preventing trapping of said detected object by controlling said drive device, said anti-trapping device having an adjustable switch lever which actuates said anti-trapping device when the predetermined pressure level is exerted; and
including a lead-through opening formed in said front face of said muffle frame and said switch lever is coupled to said anti-trapping device through said opening. - View Dependent Claims (9, 10, 11, 12)

13. A cooking device including a muffle bounding a cooking space, the cooking space accessible through a muffle opening, a substantially linear door driven by a drive unit for opening and closing the door to open and close the muffle opening, the door including a surface facing the cooking space opposite of a front face of a muffle frame surrounding the muffle opening, comprising:
an anti-trapping device which detects an object outside of said muffle opening between said door surface and said front face of said muffle frame; and
said anti-trapping device preventing trapping of said detected object by controlling said drive device, said anti-trapping device including an anti-trapping switch arranged on said front face of said muffle frame for providing signals to said anti-trapping device, including said anti-trapping switch formed as a hollow elastomeric section with at least one pressure chamber formed therein and said anti-trapping switch senses the pressure increase on said hollow elastomeric section to distinguish whether said pressure increase is due to a heating effect from said cooking space or to a trapped object.- View Dependent Claims (14, 15)
