Door handle for a cooking appliance

The innovation relates to a door handle for a cooking appliance, E.g. an oven, with a treatment room that can be locked by a door, which door handle consists of a heat Poorly conductive material and is directly connected to the door body.

With such a door handle, zti & r becomes a relatively strong one Heat gradient between the door body (door base) and the gripping area of the door handle achieved; however, are longer Operating time, e.g. of baking, is within reach detect uncomfortably high temperatures.

The innovation is based on the task of a door handle of the aforementioned type in such a way that its surface temperature is further reduced in the gripping area can be.

This object is achieved according to the Neuezmg in that at least on the part of the door handle which is directly connected to the door body and which is in the gripping area is, an additional layer is applied from a material whose thermal conductivity is even lower than that of the door handle. This layer can, for example, consist of a plastic adhesive tape or it can be sprayed on or foaming of appropriate material can be formed.

In this way, a temperature reduction on the surface of the door handle is within the reach, e.g. within the handle shell, feasible without affecting the construction the door handle would be required or a different material would have to be used for the door handle. The innovation shows particular advantages when it comes to a door handle, the so-called integrated The door handle is partially recessed behind the door front level and therefore particularly strong, e.g. from the The oven is exposed to outgoing heat. Because of this coating, which can be carried out easily and subsequently becomes the temperature on the handle surface when the door handle is grasped, i.e. in this case on the outer surface of the coating is greatly reduced compared to the temperature in the vicinity of the door handle. This coating, for example on the back of the handle, also largely prevents

that heat beam can get to the front handle part.

Advantageous details of the innovation emerge from that shown in the drawing and described below Execution example.

The figure shows a partial sectional view of an oven. Here, 1 is generally an oven housing referred to, which is connected in a known manner to an oven muffle 2 and surrounds it. Muffle 2 for its part is surrounded by an insulating layer 3 and is limited to the front side by a muffle flange 4. Die The muffle, which is open at the front, can be closed by a door 5 »which is designed, for example, as a so-called oven door is and can be moved perpendicular to the muffle flange like a drawer in the direction of the arrow and for this purpose in corresponding Rails is slidably mounted. The load-bearing part of the door is a door body or door base 6, which delimits the door forms towards the inside of the muffle. On this door base 6 are hook-like holding elements 7 for hanging baking trays and the like attached. A pane composite with two glass panes 8 is arranged in a section of the door bottom. The door bottom is pulled forward on all sides and serves there to support a front glass pane 9. On the muffle flange 4 is at least largely circumferential Door seal 10 attached, on which the closed door 5 is supported with the door base 6. On the upper boundary side of the door base 6 is not further described A so-called integrated door handle 12 is attached to the connecting means and is directly connected to the door base 6. The door handle 12 consists in the official we made of a plastic with poor thermal conductivity. He has a bowl-like Recessed grip 13, limited at the top by a

Grip extension 14 and delimited at the bottom and back by a grip wall 15 * On the horizontal port set of the grip extension Ik there are ventilation openings 16 for the recessed grip 13. As can be seen in the figure, the part directly in the gripping area of the recessed grip is within the recessed grip 13 the rear handle wall 15 and part of the horizontal extension of the handle attachment ik provided with a layer 17 which consists of a material whose thermal conductivity is even lower than that of the material from which the actual door handle 12 is made. This layer can consist of a plastic adhesive tape which is glued to the aforementioned handle parts or can be applied in a spray or foam process to form the layer 17.

Claims (3)

TZP 83/635 protection claims 1. Door handle for a cooking appliance, for example an oven, with a treatment room that can be closed by a door, which door handle consists of a material with poor heat conductivity and is directly connected to the door body, characterized in that at least on the part (15) of the door handle (12 ), which is directly connected to the door body (6) and which is in the gripping area, an additional layer (17) is applied made of a material whose thermal conductivity is even lower than that of the door handle. 2. Door handle according to claim 1, characterized in that the layer (17) consists of a plastic adhesive tape. 3. Door handle according to claim 1, characterized in that the layer consists of a sprayed or foamed Material consists.
