Hygiene-compliant display and control device

摘要

Machines and systems for chemical, foodstuffs and pharmaceuticals industry are subject to particularly demanding requirements for hygiene. In particular, equipment used in such machines, must avoid any gaps, in which dirt, bacteria or germs could settle. To avoid this, a hygiene-compliant display and control device having a front plate is proposed, having a peripheral groove, which is open on the outer peripheral surface of the front plate, on the outer edge of the front plate, and a sealing element fitted in the peripheral groove. The outer peripheral surface of the sealing element is arranged flush with the outer peripheral surface of the front plate, and a number of clamping arrangements with a pressing element are provided on the display and control device distributed around the periphery. One axial end of the pressing element engages with a fixing frame, which rests on the mounting plate, or with the mounting plate.

主权项

1. A hygiene-compliant display and control device comprising:
a front plate having an outer peripheral surface on an edge of the front plate and a peripheral groove provided on and open to the outer peripheral surface; a body, extending from the front plate; a mounting plate; a sealing element arranged in the peripheral groove and being positionable between the edge of the front plate and the mounting plate, wherein, in a particular state, an outer peripheral surface of the sealing element is arranged flush with the outer peripheral surface of the front plate; a plurality of clamping units being distributed around a periphery of the body and being structured and arranged to face the edge of the front plate and to create, with the edge of the front plate, a clamping connection, each of the clamping units comprising a pressing element; a fixing frame contacts and rests against the mounting plate and engages with axial ends of the pressing elements; and the mounting plate contacts the fixing frame and the sealing element of the front plate.
