Embodiment Construction

[0024] The refrigerator and freezer 1 shown in FIG. 1 comprises a substantially cuboidal body 2 which is closable by means of a door 3 which is pivotally mounted on this body 2 in a manner known per se and which extends around The vertical door rotation axis 4 rotates.

[0025] According to the embodiment shown in FIG. 2, the door operating device 5 includes an electric motor 6. In the illustrated embodiment, the electric motor 6 is installed on the body 2 and can rotate and open the door 3 through a gear transmission mechanism 7. closure. In the illustrated embodiment, the gear transmission mechanism 7 is a bevel gear transmission and is arranged at a position close to the door rotation axis 4, so that a larger rotation range can be achieved with a smaller size.

[0026] As shown in Figure 2, a slip clutch 8 is incorporated into the drive train from the electric motor 6 to the gear train 7, which ensures that when the door hits an obstacle, the movement of the door is stoppe...

Abstract

The invention relates to a refrigerating and / or freezing appliance comprising a body that can be closed by at least one door, and a motor-driven door-actuating device for automatically actuating the door. The inventive refrigerating and / or freezing appliance is characterised in that the door-actuating device comprises drive means for both automatically closing and automatically opening the door.

Description

technical field [0001] The invention relates to a refrigerator and / or freezer with a body which can be closed by means of at least one door and a powered door operating device for automatically controlling the door. Background technique [0002] DE 203 01 951 U1 discloses a refrigerator and freezer whose door is pushed open by a motor and a tappet driven by the motor to facilitate opening the door and in particular to overcome the Door seal retention and vacuum suction. The tappet is driven by a motor through an eccentric and disengages it after initially pushing the door open, allowing the door to be further opened by hand and closed again. Wherein, when the door is opened, the lifter is returned to the retracted position of the lifter by the motor, so that the door can be closed. While such door opening aids greatly facilitate door opening of refrigerator and freezer appliances, further simplification of door operation is desired. For example, when refrigerated items mu...
