Hladilni aparat, zlasti no-frost uparjalnik vsebujoč hladilni aparatRefrigeration apparatus, in particular a no-frost evaporator containing refrigeration apparatus

Predloženi izum se nanaša na gospodinjski aparat, zlasti na hladilni aparat, kot na primer hladilnik, zamrzovalnik, kombinirani hladilnik in zamrzovalnik, hladilnik za hlajenje pijač in podobno, ki v zgornjem območju vsebuje tako imenovano no-frost uparjalno enoto, ki je zakrita z zaščitnim zaslonom, s čimer se prepreči nedovoljen dostop do no-frost uparjalne enote.The present invention relates to a household appliance, in particular a refrigeration appliance, such as a refrigerator, freezer, combination refrigerator and freezer, beverage refrigeration refrigerator, and the like, containing in the upper region a so-called no-frost evaporator unit covered by a protective screen to prevent unauthorized access to the no-frost evaporator unit.

Znani hladilni aparati uvodoma navedene vrste predvidevajo uporabo zaščitnega zaslona, sestavljenega iz ločenega okrasnega pokrova in ločene letve, ki sta pritrjena s pomočjo vijakov in/ali dodatnih plastičnih elementov. Namen vijakov in dodatnih elementov je z obliko ali trenjem preprečiti nenadno snetje pritrjenih sestavnih delov in s tem dostop do nevarnih delov aparata. Po drugi strani pa je dostop do nevarnih delov aparata omogočen le z uporabo orodja. Pomanjkljivost dosedanjih znanih rešitev leži v tem, da so po eni strani zamudne za montažo, po drugi pa cenovno neugodne. Pri montaži in/ali demontaži pogosto pride do obrabe ali celo porušitve navojev in/ali plastičnih elementov, zaradi česar jih je marsikdaj nemogoče zamenjati ali jih je potrebno sorazmerno pogosto menjati. Poleg tega je stik med okrasnim pokrovom in okrasno letvijo povsem viden, kar prispeva k neestetskemu videzu aparata.Known refrigeration apparatus of the foregoing type envisage the use of a protective screen consisting of a separate decorative cover and a separate strip, which are secured by means of screws and / or additional plastic elements. The purpose of screws and additional elements is to prevent, by form or friction, the sudden removal of attached components and thereby access to dangerous parts of the apparatus. On the other hand, access to hazardous parts of the appliance is only possible through the use of tools. The disadvantage of the known solutions so far is that they are expensive to install on the one hand and cost disadvantageous on the other. When mounting and / or dismantling, there is often wear and tear or even tearing of the threads and / or plastic elements, making them often impossible to replace or need to be changed relatively frequently. In addition, the contact between the hood and the trim is quite visible, contributing to the aesthetic appearance of the appliance.
