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 said inner compartment and a device for opening/closing said door, characterized in that said device for opening/closing the door comprises means for imparting a lateral rotational-translational motion to the door relative to said front wall, thereby effecting said opening/closing action, wherein said means for imparting a rotational-translational motion to the door comprises: - a U-shaped handle, comprising a central part and ends (45'', 45''') hinged to said front part via first hinging means (43, 44) arranged in a laterally cantilevered position relative to the door; - second hinging means (48, 49) providing a connection between a first side of the door and said central part of the handle; - third hinging means arranged at an upper end of the door on a second side thereof opposite to said first side, said 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 said handle about said first hinging means causing said rotational-translational motion for opening/closing the door, such that said first side rotates relative to said front wall, and said second side translates laterally relative to said front wall. 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 said inner compartment and a device for opening/closing said door, characterized in that said device for opening/closing the door comprises means for imparting a lateral rotational-translational motion to the door relative to said front wall, thereby effecting said opening/closing action, wherein said means for imparting a rotational-translational motion to the door comprises: - a U-shaped handle, comprising a central part and ends (45'', 45''') hinged to said front part via first hinging means (43, 44) arranged in a laterally cantilevered position relative to the door; - second hinging means (48, 49) providing a connection between a first side of the door and said central part of the handle; - third hinging means arranged at an upper end of the door on a second side thereof opposite to said first side, said 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 said handle about said first hinging means causing said rotational-translational motion for opening/closing the door, such that said first side rotates relative to said front wall, and said second side translates laterally relative to said front wall. - a U-shaped handle, comprising a central part and ends (45'', 45''') hinged to said front part via first hinging means (43, 44) arranged in a laterally cantilevered position relative to the door; - second hinging means (48, 49) providing a connection between a first side of the door and said central part of the handle; - third hinging means arranged at an upper end of the door on a second side thereof opposite to said first side, said 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 said handle about said first hinging means causing said rotational-translational motion for opening/closing the door, such that said first side rotates relative to said front wall, and said second side translates laterally relative to said front wall.
