SESTAV TEČAJA VRAT PEČICE GOSPODINJSKEGA APARATA Z DUŠENIM ZAPIRANJEMHOUSEHOLD OVEN DOOR HINGER COMPOSITION COMPOSITION WITH SOUL CLOSED

Predmet izumaThe subject of the invention

Predmet izuma je sestav tečaja vrat pečice gospodinjskega aparata z dušenim zapiranjem vrat pečice gospodinjskega aparata iz vmesne priprte lege vrat pečice v končno zaprto lego vrat pečice skladno z uvodnim delom prvega patentnega zahtevka.The subject of the invention is the assembly of the hinge door hinge of the domestic appliance by the damped closing of the door of the domestic appliance oven from the intermediate closed position of the oven door to the closed end position of the oven door according to the introductory part of the first patent claim.

Tehnični problemA technical problem

Tehnični problem, ki ga rešuje izum, je kako zasnovati tečaj za vrata pečice gospodinjskega aparata opisanega v patentni prijavi P 2005 0 0243 istega prijavitelja, da bo omogočal dušeno zapiranje iz priprte lege v zaprto lego in pri tem ne bo bistveno posegel v obstoječo konstrukcijo tečaja vrat niti pečice gospodinjskega aparata in hkrati ne bo posegal v manipulacijski prostor med pečico in vrati pečice, pri čemer pa se mora ohraniti prvotna enostavna konstrukcija in montaža tečaja.A technical problem solved by the invention is how to design a hinge door for a household appliance described in patent application P 2005 0 0243 by the same applicant so that it can be damped from closed to closed position without significantly affecting the existing hinge structure door or oven of the domestic appliance and at the same time it will not interfere with the manipulation space between the oven and the oven door, while maintaining the original simple construction and mounting of the hinge.

Znano stanje tehnikeThe prior art

Tečaji vrat gospodinjske pečice morajo zaradi različnih zahtev pri kuhanju in pečenju omogočati priprtost vrat v vmesni legi med popolnoma zaprtimi oziroma odprtimi vrati, kar je rešeno na različne znane načine. Zaradi konstrukcije, ki omogoča tako pripiranje vrat, je zadnja faza zapiranja iz priprte v zaprto lego največkrat sunkovita, glasna in lahko povzroči celo poškodbe, zlasti prstov. Sunkovito zapiranje vrat v zadnji, sklepni fazi zapiranja se rešuje z različno zasnovanimi blažilniki, ki so nameščeni na notranji strani vrat pečice ali delno vgrajeni v ohišje pečice in posegajo v manipulacijski prostor. Zaradi tega morajo biti temperaturno obstojni, hkrati pa se jim zaradi velike verjetnosti zamastitve zmanjšuje življenjska doba. Tak je primer, ki je opisan v DE 10 2007 029696. V primerih, ko so blažilniki nameščeni v notranjosti vrat pečice, je njihova konstrukcija zapletena, sestavljajo jih številni sestavni deli, kotDue to the different cooking and baking requirements, the hinges of the oven door hinges must allow the door to be closed in an intermediate position between fully closed or open doors, which is solved in various known ways. Due to the structure that allows the door to be closed, the final closing phase from closed to closed is often jerky, loud and can even cause damage, especially to the fingers. The sudden closing of the door in the final, closing phase of the closing is solved by variously designed dampers, which are mounted on the inside of the oven door or partially integrated into the oven housing and encroach on the manipulation room. As a result, they have to be temperature resistant and, at the same time, have a high likelihood of fouling, reducing their service life. This is the case described in DE 10 2007 029696. In cases where the shock absorbers are located inside the oven door, their construction is complex, consisting of many components, such as

je npr. opisano v patentni prijavi EP 2362050. Tu je opisana rešitev blaženja vrat gospodinjske pečice z namensko konstruiranim blažilnikom, kije nameščen na koncu kraka tečaja vrat gospodinjske pečice in sega v predel pečice tako, daje oddaljen od vrat pečice. Pnevmatski blažilnik, v katerem je razporejen bat, je na krak tečaja pritrjen preko zaskočne zveze. Z batom nalega na poševni element, ki je prožen s posebnim potisnim elementom. Potisni element se nahaja v ohišju kraka tečaja in njegovo delovanje je preko več vzvodov povezano z gibanjem kraka tečaja. Sam blažilnik je sicer na enostaven način povezan s krakom tečaja pečice vrat, je pa njegovo proženje in delovanje povezano s številnimi konstrukcijskimi elementi znotraj osnovnega tečaja vrat. Posledica je zahtevna in komplicirana montaža s številnimi sestavnimi deli, kar znatno podraži proizvodnjo in hkrati oteži avtomatsko sestavljanje komponente. Dodatna slabost zaradi številnih med seboj mehansko povezanih delov je tudi velika možnost onesnaženja, zlasti zamastitve elementov, kar zmanjšuje življenjsko dobo omenjenega tečaja.is e.g. described in patent application EP 2362050. This describes a solution for damping the oven door with a purpose-built damper, which is located at the end of the hinge door hinge arm and extends into the oven compartment so that it is away from the oven door. The pneumatic damper in which the piston is arranged is secured to the hinge via a snap link. With the piston, it rests on an oblique element, which is flexible with a special thrust element. The thrust element is located in the hinge housing and its operation is connected to the movement of the hinge via several levers. The damper itself is connected to the door hinge hinge in a simple way, but its actuation and operation are related to many structural elements within the basic hinge. The result is complex and complicated assembly with many components, which significantly increases the cost of production and makes it difficult to assemble the component automatically. An additional disadvantage due to the many mechanically interconnected parts is the great potential for contamination, especially of the elements, which reduces the life of the hinge.

Rešitev tehničnega problemaThe solution to a technical problem

Opisani tehnični problem je rešen z izvedbo po izumu tako, da je v znani osnovni konstrukciji tečaja, kije opisana v patentni prijavi P 2005 0 0243 istega prijavitelja na bočnih pasovih ohišja izveden podolgovati izsek, znotraj katerega je prosto pomičen omejilni somik, ki je nepomično razmeščen na dvokrakem vezniku v območju kljunastega držala in da kljunasto držalo vsebuje daljšemu kraku v bistvu vzporedno razmeščeno skoznjo vodilno luknjo, v kateri se nahaja naležni somik, pri čemer naležni somik s svojim enim prostim koncem nalega na omejilni somik, medtem ko drugi prosti konec naležnega somika nalega na soosno na nosilnem ohišju razporejen blažilnik.The described technical problem is solved by the embodiment according to the invention, so that in the known basic construction of the hinge described in patent application P 2005 0 0243, an elongated section is formed on the lateral belts of the housing, within which the limiting jumper, which is fixedly disposed, is freely movable on a two-pointed binder in the region of the beak-holder, and that the beak-holder contains, in a substantially parallel manner, a substantially parallel guide hole in which the contact catfish is located, with the one catcher with one free end resting on the bounding catfish, while the other free end of the catfish catcher a shock absorber mounted on a coaxial housing.

Sestav 100 tečaja vrat pečice gospodinjskega aparata za dušeno zapiranje vrat pečice gospodinjskega aparata iz priprte lege vrat v končno zaprto lego vrat je izveden iz tečaja 50 vrat pečice gospodinjskega aparata, nameščenega v vratih (niso prikazana) pečice, nosilnega ohišja 60, nameščenega na notranji strani zunanje stene ohišja pečice (ni prikazana) in blažilnika 70 . Tečaj 50 vrat vsebuje ohišje 1, ki se nahaja v vratih pečice gospodinjskega aparata, znotraj ohišja 1 nahajajoč se mehanizem 16, vsebujoč ohišni element, vzporedni vzmeti in valjček na somiku, za držanje vrat pečice v priprti legi, kot je opisan v patentu SI 9600318 istega prijavitelja, in kljunasto držalo 4, ki pri zapiranju/odpiranju vrat pečice in držanju le-teh v priprti legi preko valjčka, sodeluje z mehanizmom 16 za držanje vrat pečice v priprti legi.The door hinge assembly 100 for the throttle door closure of the domestic appliance from the closed door position to the closed end position of the door is derived from the door hinge door hinge 50 installed in the door (not shown) of the oven, housing 60 mounted on the inside the outer walls of the oven casing (not shown) and the damper 70. The 50 door hinge comprises a housing 1 located in the oven door of the domestic appliance, inside the housing 1 a mechanism 16, comprising a housing element, parallel springs and a roller on the catcher, for holding the oven door in the closed position as described in patent SI 9600318 of the same applicant, and a beak holder 4 which cooperates with the mechanism 16 for holding the oven door in the closed position when closing / opening the oven door and holding it in the closed position via a roller.

Ohišje 1 je nameščeno na notranji steni vrat pečice gospodinjskega aparata, ki niso prikazana, in je izvedeno kot U profil s poljubnimi znanimi pritrdišči 2, npr. izvrtinami ali jezički, na ohišje vrat pečice. Na bočnih pasovih ohišja 1 so izvedeni izseki 5, 5' z zavihki, ki določajo območje vgraditve mehanizma 16 za držanje vrat pečice v priprti legi, kot je opisano v predhodnem patentu prijavitelja. Na enem koncu ohišja 1 je zasukljivo na somiku 3 uležajeno kljunasto držalo 4 vrat pečice. V ohišju 1 je nadalje izveden izsek 8, skozi katerega štrli kljunasto držalo 4 in omogoča sukanje okrog kljunastega držala 4 za približno pravi kot, oziroma kolikor je potrebno, da se odpirajo vrata pečice. Nadalje je na bočnih pasovih ohišja 1 izveden podolgovati izsek 6, katerega funkcija bo opisana kasneje.The housing 1 is mounted on the inner wall of the oven door of the domestic appliance, which is not shown, and is made as a U profile with any known anchorages 2, e.g. holes or tabs on the oven door housing. The flanges 5, 5 'with flaps defining the mounting area of the mechanism 16 for holding the oven door in the closed position as described in the prior patent of the applicant are made on the side belts of the housing 1. At one end of the housing 1 there is a rotatable beak holder 4 on the socket 3 of the oven door 4. In the housing 1, a section 8 is further made through which the beak holder 4 protrudes and allows rotation around the beak holder 4 by approximately the right angle or as needed to open the oven door. Further, an elongated section 6 is performed on the sidebands of the housing 1, the function of which will be described later.

Kljunasto držalo 4 je v bližini svojega uležajenja v somik 3 zasukljivo vpeto v somiku 30 preko dvokrakega veznika 9 na vzmet 10, ki je na drugem koncu vpeta preko somika 11 v ohišje 1 in sicer v zeva 12. Vzmet 10 je v dvokrakem vezniku 9 nameščena v izvrtini 91, medtem ko s svojim kavljastim koncem objema somik 11. Somik 11 je v zevu samo vložen, napeta vzmet 10 pa preprečuje izpad somika 11 iz zeva. Na dvokrakem vezniku 9 je v območju kljunastega držala 4 nepomično razmeščen omejilni somik 18 tako, da s svojima koncema sega v vsakokratni podolgovati izsek 6 na bočnih pasovih ohišja 1 in je znotraj izseka 6 prosto pomičen.The beak retainer 4 is rotatably fastened in the nozzle 30 near its bearing 3 by a two-pointed binder 9 to the spring 10, which is secured at the other end via a bell 11 to the housing 1 and into the yoke 12. The spring 10 is mounted in the two-pointed binder 9 in the hole 91, while with its hook end, it grips the catfish 11. The catfish 11 is only inserted in the yawn, and the taut spring 10 prevents the catfish 11 from escaping. On the two-way link 9, a restraining snap 18 is disposed in the region of the beak retainer 4 so that its ends extend into the respective elongate section 6 on the side belts of the housing 1 and are freely movable within the section 6.

Kljunasto držalo 4 je v območju somika 3 mogoče izvesti z razširitvijo, v prednostni izvedbi v smislu dvokrakega dela, da je zagotovljena večja trdnosti na morebitne bočne sile, ki lahko nastopijo pri odpiranju in zapiranju vrat. V taki izvedbi je tudi uležajenje dvokrakega veznika 9 v kljunasto držalo 4 s pomočjo sornika 30 izvedeno v območju razširitve.The beak retainer 4 can be extended in the area of the aperture 3, preferably in the form of a two-handed part, to provide greater strength to any lateral forces that may occur when opening and closing the door. In such an embodiment, the mounting of the two-pointed binder 9 into the beak retainer 4 by means of a bolt 30 is also carried out in the extension zone.

Kljunasto držalo 4 je izvedeno kot črka L, pri čemer je krajši krak uležajen v somiku 3, daljši krak sega skozi izsek 8 v nasproti ohišju 1 ležeče nosilno ohišje 60, ki je pritrjeno na notranji strani zunanje stene pečice. Na konveksni strani stika obeh krakov je izvedena grba 13, ki potuje med odpiranjem oziroma zapiranjem vrat skozi izsek 8 ohišja 1 in ki v določenem kotu fiksira priprta vrata, konkavna stran stika obeh krakov vsebuje ojačitveno rebro 14. Kljunasto držalo 4 vsebuje daljšemu kraku v bistvu vzporedno razmeščeno skoznjo vodilno luknjo 15, v kateri se nahaja naležni somik 17. Naležni somik 17 držala je v svoji vzdolžni osi gibljiv in je njegova dolžina večja od dolžina vodilne luknje 15. Ko so vrata pečice gospodinjskega aparata v priprti legi, naležni somik 17 s svojim koncem nalega na omejilni somik 18, medtem ko drugi prosti konec naležnega somika 17 nalega na soosno na nosilnem ohišju 60 razporejen blažilnik 70 znane vrste. Blažilnik 70 je na nosilno ohišje 60 pritrjen tako, da izkorišča prostor med toplotno izolacijo pečice in zunanjo steno pečice. S tako razporeditvijo blažilnik ne posega v manipulacijski prostor, je tesno zaprt za zunanje vplive s čimer je preprečeno njegovo zamaščevanje, razporejen je simetrično na obeh straneh vrat pečice, s čimer je zagotovljeno enakomerno dušeno zapiranje vrat.The beak retainer 4 is formed as the letter L, with the shorter arm resting in the snail 3, the longer arm extending through the section 8 in the housing 1 opposite to the housing 1, which is secured to the inside of the outer wall of the oven. On the convex side of the joint of the two arms is provided a coat of arms 13 which travels during the opening or closing of the door through the section 8 of the housing 1 and which fixes the door closed at a certain angle, the concave side of the contact of the two arms contains a reinforcing rib 14. The beak holder 4 contains a longer arm substantially parallel to the leading hole 15 in which the contact snap 17 is located. The retainer cat 17 is movable in its longitudinal axis and its length is greater than the length of the guide hole 15. When the oven door of the household appliance is in the closed position, the contact snail 17 s its end rests on the restraint catcher 18, while the other free end of the contact catcher 17 rests on a coaxially mounted shock absorber 70 of a known type. The damper 70 is fixed to the supporting housing 60 to take advantage of the space between the thermal insulation of the oven and the outer wall of the oven. With this arrangement, the damper does not interfere with the manipulation space, it is tightly closed to external influences to prevent its clogging, it is arranged symmetrically on both sides of the oven door, thus ensuring evenly damped door closure.

Tečaj 50 vrat pečice je z zaklepom 19 znane in poljubne vrste, ki je nameščen na kljunastem držalu 4, ločljivo povezan z nosilnim ohišjem 60.The hinge 50 of the oven door is detachably connected to the carrier housing 60 by a lock 19 of a known and arbitrary type mounted on the beak holder 4.

Razume se, da lahko strokovnjak s tega področja na osnovi poznavanja gornjega opisa izuma zasnuje tudi drugačne izvedbene primere, ne da bi obšel značilnosti in novosti izuma, kot so opredeljene v sledečih patentnih zahtevkih.It is understood that one of skill in the art may, on the basis of knowledge of the foregoing description of the invention, also conceive different embodiments without circumventing the features and novelties of the invention as defined in the following claims.
