PRIPRAVA ZA PRITRDITEV PLINSKE NAPELJAVE V GOSPODINJSKEM APARATUPREPARATION FOR MOUNTING OF THE GAS IN THE HOUSEHOLD APPARATUS

[0001] Predlagani izum se nanaša na gospodinjski aparat, konkretneje na samostoječi oz. vgradni plinski štedilnik, ki obsega ohišje s kuhalno površino in pečico, pri čemer je na kuhalni površini nameščen vsaj en plinski gorilnik, ki se ga s plinom oskrbuje preko oskrbovalnega sklopa, obsegajočega glavno dovodno plinsko cev z vsaj enim plinskim zapornim elementom, pri čemer je glavna dovodna plinska cev s pomočjo vsaj enega pritrdilnega sredstva pritrjena na ohišje gospodinjskega aparata.[0001] The present invention relates to a household appliance, more specifically to a stand-alone or a built-in gas cooker comprising a hob with a hob and an oven, wherein at least one gas burner is provided on the hob and is supplied to the gas through a supply assembly comprising a main gas supply pipe with at least one gas shut-off element, wherein the main gas inlet hose is attached to the housing of the household appliance by means of at least one fastener.

[0002] Znani gospodinjski aparati, na primer samostoječi oziroma vgradni plinski štedilniki, imajo omenjeni oskrbovalni sklop pritrjen preko glavne dovodne plinske cevi pritrjen na sprednjo steno štedilnika oz. na upogib na zgornjem robu omenjene stene. Omenjena stena štedilnika je običajno izdelana iz tanke pločevine, zaradi česar je izpostavljena deformacijam zaradi nihanja mehanskih lastnosti materiala in postopka emajliranja. Poleg tega je razdalja med točko pritrditve glavne dovodne plinske cevi na sprednjo steno in vretenom plinskega ventila sorazmerno velika, kar lahko privede do dodatnih dimenzijskih odstopanj.[0002] Known household appliances, such as freestanding or built-in gas cookers, have said supply assembly attached via a main gas supply pipe to the front wall of the cooker or. to the bend at the upper edge of said wall. Said wall of the cooker is usually made of thin sheet metal, which makes it subject to deformation due to fluctuations in the mechanical properties of the material and the enameling process. In addition, the distance between the attachment point of the main gas inlet pipe to the front wall and the gas valve spindle is relatively large, which may lead to additional dimensional deviations.

[0003] Znani so tudi gospodinjski aparati uvodoma navedene vrste, kjer je glavna dovodna plinska cev s posebnim nosilcem pritrjena neposredno na s prirobnico zasnovanem izseku na čelni plošči gospodinjskega aparata, ki je sicer predviden za namestitev električnih stikal. Tovrstna pritrditev sicer omogoča neposredno pritrditev glavne dovodne plinske cevi, pri čemer pa kasneje ni omogočen nikakršen poseg več v omenjeno pritrditev oz. prilagoditev le-te.[0003] Household appliances of the aforementioned type are also known, wherein the main gas inlet pipe with a special carrier is attached directly to a flange-shaped section on the front panel of the household apparatus, which is otherwise intended to be fitted with electrical switches. This kind of attachment allows direct attachment of the main gas inlet pipe, but later no further interference with said attachment or connection is possible. adjusting it.

[0004] Naloga predlaganega izuma je ustvariti gospodinjski aparat uvodoma navedene vrste, pri katerem je pritrditev plinske napeljave zanesljiva in ponovljiva, tako da so odpravljene pomanjkljivosti znanih rešitev.[0004] The object of the present invention is to provide a household appliance of the type mentioned above in which the fixing of the gas line is reliable and reproducible, so that the disadvantages of the known solutions are eliminated.
