Abstract

A washing machine adapted for washing equipment used in the field of pharmaceutical research and/or pharmaceutical production is described, which includes an inner compartment and a front wall having a door allowing access to the inner compartment and a device for opening/closing the door, the device for opening/closing the door includes components for imparting a lateral rotational-translational motion to the door relative to the front wall, thereby effecting the opening/closing action.

Claims

1. A washing machine adapted for washing equipment used in the field of pharmaceutical research and/or pharmaceutical production, comprising an inner compartment and a front wall comprising a door allowing access to the inner compartment and a device for opening/closing the door, wherein the device for opening/closing the door comprises a system configured for imparting a lateral rotational-translational motion to the door relative to the front wall, thereby effecting the opening/closing action.

2. The washing machine according to claim 1, comprising an automated system for opening/closing the door, connected to the system configured for imparting a lateral rotational-translational motion to the door.

3. The washing machine according to claim 1, wherein the system configured for imparting a rotational-translational motion to the door comprises:

a U-shaped handle, comprising a central part and ends hinged to the front part via a first hinge arranged in a laterally cantilevered position relative to the door;

a second hinge providing a connection between a first side of the door and the central part of the handle;

a third hinge arranged at an upper end of the door on a second side thereof opposite to the first side, the third hinging means sliding in a horizontal guide parallel to the front side of the machine and situated on the upper part of the door;

the rotation of the handle about the first hinge causing the rotational-translational motion for opening/closing the door, such that the first side rotates relative to the front wall and the second side translates laterally relative to the front wall.

4. The washing machine according to claim 3, wherein the second hinge comprises fasteners shaped as tube sections, fixedly connected to the handle and hingedly connected to the door.

5. The washing machine according to claim 4, wherein the automated system for opening/closing the door comprises a pneumatic cylinder connected to the handle via a fourth hinge and to the machine via a fifth hinge.

6. The washing machine according to claim 5, wherein the pneumatic cylinder is positioned above the inner compartment of the machine.

7. A device for opening/closing the door of a washing machine adapted for washing equipment used in the field of pharmaceutical research and/or pharmaceutical production, comprising a system configured for imparting a rotational-translational motion to the door in order to effect the opening/closing action, as claimed in claim 1.
