Abstract

The so far execution of a door on a household oven, which is composed of a housing of the appliance (1), a control panel (2) and a heating chamber or baking chamber (3), is the one with a single wing door (4). Such a door occupies a lot of space in front of the appliance (v1) when opened, makes the access to the interior of the appliance more difficult and causes a great drop in temperature when opening the oven. These drawbacks are eliminated by a vertically sliding door composed of two horizontally separated parts (7) and (8). During opening, the upper part of the door is moving outwards and upwards, yet being positioned horizontally all the time, and the lower part is moving outwards and downwards. The opened door (7a) and (8a) moves to the space (v2) only so much that it does not lean against the control panel or against a rail or a drawer. Such a property assures a minimum displacement of the door to the space in front of the appliance as well as an unimpeded access to the appliance. It enables also the use of a smaller door opening when loading the oven, which contributes to a smaller drop of temperature within the appliance during its opening.

VRATA GOSPODINJSKEGA APARATADOORS OF THE HOUSEHOLD APPARATUS

Izum se nanaša na vrata gospodinjskega aparata, v osnovi samostojne ali vgradne gospodinjske pečice, lahko pa tudi gostinske, ki so vertikalno premična.The invention relates to the door of a household appliance, basically a stand-alone or built-in household oven, but also catering units that are vertically movable.

Izum je po IPC standardu uvrščen v kategorijo F24C 15/02.The invention is classified under F24C 15/02 by the IPC standard.

Vertikalno premična vrata rešijo več problemov. Prvo je zanemarljivo mala poraba prostora pred aparatom, ko se vrata odpirajo in ko so vrata popolnoma odprta. Druga rešitev je lažji dostop do notranjosti pečice. Tretja rešitev, ki jo nudijo takšna vrata, pa je uporaba manjše odprtine vrat pri vstavljanju, kar pripomore k manjšemu padcu temperature v grelnem prostoru.Vertically movable doors solve several problems. The first is the negligible use of space in front of the appliance when the door opens and when the door is fully open. Another solution is easier access to the inside of the oven. The third solution offered by such a door is to use a smaller door opening when inserting, which helps to reduce the temperature in the heating compartment.

Dosedanja znana rešitev oz. izvedba vrat je takšna, da so vrata pritrjena na spodnjem robu aparata in se z zgornje strani odprejo stran od aparata v prostor in navzdol. Takšna izvedba ima precej pomanjkljivosti.The known solution so far or. the design of the door is such that the door is fixed at the bottom edge of the appliance and opens from the top side away from the appliance into the room and down. There are many drawbacks to such an implementation.

Kot prvo se pojavi potreba po velikem prostoru pred aparatom. Ker se vrata odpirajo navzven, zahtevajo pred aparatom prostor vsaj za višino vrat. Druga slabost pri tako odprtih vratih je omejen dostop do notranjosti pečice. Dostop je možen s sprednje strani, vendar z velike oddaljenosti, ker prostor pred aparatom zasedajo odprta vrata, ali pa s strani, kar pa tudi ni priročno. Naslednja pomanjkljivost pa je, da se morajo vrata v večini primerov odpreti do konca, da se lahko vstavi ali pa odstrani pekač. Medtem, ko so vrata odprta na tak način, v prostor aparata vdira veliko hladnega zraka in hkrati izhaja veliko vročega. S tem se med vstavljanjem in odstranjevanjem pekača temperatura v pečici zelo zniža, kar ponavadi ni primemo v procesu peke.First, there is a need for a large space in front of the appliance. Since the door opens outwards, they require space at least for the height of the door in front of the appliance. Another drawback with the door open is limited access to the oven interior. Access is possible from the front, but from a great distance, since the space in front of the appliance is occupied by an open door, or from the side, which is not convenient. Another disadvantage, however, is that in most cases the door must be fully open to allow the baking tray to be inserted or removed. While the door is opened in this way, a lot of cold air enters the room and a lot of hot air flows. This greatly reduces the oven temperature during insertion and removal of the baking tray, which is usually not observed in the baking process.

Z vertikalno pomičnim načinom odpiranja vrat se predstavljenim problemom izognemo. Na naslednjih slikah je prikazana primerjava omenjenega dosedanjega stanja in izuma ter sestava in način odpiranja vrat.With the vertically sliding door opening method, the problems presented are avoided. The following figures show a comparison of the present state of the invention and the composition and method of opening the door.

Sedanja izvedba vrat na pečici je prikazana na sliki 1. Aparat sestavlja ohišje aparata (1), komandna plošča (2), grelni prostor oz. prostor za peko (3), ki je zaprt z enojnimi vrati (4). Vrata so vpeta v tečaju na spodnjem delu (5) in se odpirajo z zgornje strani navzven in navzdol. Kot se vidi s slike, takšna izvedba zahteva najmanj za višino vrat aparata prostora pred aparatom (vi).The current version of the oven door is shown in Figure 1. The appliance consists of the housing of the appliance (1), the control panel (2), the heating compartment or. baking space (3) closed by single doors (4). The door is clamped in the hinge at the bottom (5) and opens from the upper side inwards and downwards. As can be seen from the figure, such a design requires at least the height of the door of the appliance space in front of the appliance (you).

Na sliki 2 pa je prikazana izvedba z vertikalno premičnimi vrati. Aparat ima za razliko od obstoječe izvedbe, dvodelna vrata. Oznaki (7) in (8) označujeta zaprta vrata, medtem ko so s (7a) in (8a) označena odprta vrata. Vrata so horizontalno ločena in vertikalno gibljiva. Ko so vrata zaprta, se spodnji rob zgornjih vrat (7) in zgornji rob spodnjih vrat (8) ujemata, tako da ne prepuščata toplote iz notranjosti aparata.Figure 2, however, shows a design with vertically movable doors. Unlike the existing version, the appliance has a two-piece door. Marks (7) and (8) denote closed doors, while (7a) and (8a) denote open doors. The door is horizontally separated and vertically movable. When the door is closed, the lower edge of the upper door (7) and the upper edge of the lower door (8) match so that no heat is released from the inside of the appliance.

Med odpiranjem vrat aparata, se zgornja vrata pomikajo navzven in navzgor, vendar so ves čas postavljena horizontalno, za razliko od dosedanjega postopka odpiranja, kjer vrata rotirajo okoli tečaja na spodnji strani. Za spodnji del vrat velja podobno; med odpiranjem so v vertikalni poziciji, kot takrat, ko so zaprta, pomikajo pa se navzven in navzdol. Zgornji (7) in spodnji (8) del vrat se morata pri odpiranju pomakniti v smeri od aparata v prostor (v2) le toliko, da se ne naslonita zgoraj na kontrolno ploščo, in spodaj na letev ali predal, odvisno od izvedbe aparata. Proces odpiranja vrat je prikazan na sliki 3 in si sledi po korakih od (ki) do (k3), medtem, ko proces zapiranja vrat poteka v obratnem vrstnem redu kot odpiranje, v korakih od (k3) do (ki). Izometrično sliko aparata z odprtimi vertikalno premičnimi vrati pa prikazuje slika 4.When opening the door of the appliance, the upper door moves inwards and upwards, but is permanently positioned horizontally, unlike the previous opening procedure, where the doors rotate around the hinge on the underside. The lower part of the door is similar; they are in a vertical position when opened, as they are closed, and move up and down. The upper (7) and lower (8) portions of the door must, when opened, move away from the appliance into the room (v2) only so that they do not lean upwards on the control panel and down on the lath or drawer, depending on the version of the appliance. The door opening process is shown in Figure 3 and is followed in steps (ki) to (k3), while the door closing process is in the reverse order of opening, in steps (k3) to (ki). The isometric image of the apparatus with the vertically movable door open is shown in Figure 4.

Specifičnost odpiranja vertikalno pomičnih vrat pa določa tudi postavitev ročajev oziroma ročic (9) za odpiranje vrat. Ko se vrata odprejo, topel oz. vroč zrak iz grelnega prostora hitro prodre v prostor navzgor in tudi ob zgornjem delu vrat (7). Na, do sedaj znanih, rotirajoče se odpirajočih enojnih vratih, je ročaj za odpiranje vrat horizontalno na zgornjem delu vrat. Ker pa bi bil zaradi omenjenega pojava na tem delu večji pretok toplega oz. vročega zraka, je uporaba takšnega ročaja v predlaganem primeru neprimerna. Zaradi tega mora biti ročica na strani vrat, kjer je stena in ni neposrednega toka toplote iz notranjosti aparata. S tem zagotovimo varno odpiranje in zapiranje vrat. Ker pa se lahko vrata odpirajo z različnih strani, je najbolj primemo, da sta ročici za odpiranje nameščeni vsaka na svoji strani vrat.The specificity of opening vertically sliding doors also determines the positioning of the handles or levers (9) for opening the door. When the door opens, warm or warm. hot air from the heating compartment quickly penetrates the compartment upwards as well as at the top of the door (7). On the hitherto known rotating single door, the door handle is horizontal at the top of the door. However, because of the mentioned phenomenon, a higher flow of warm or hot water would be in this part. the use of such a handle is inappropriate in the proposed case. For this reason, the lever must be on the side of the door where the wall is and there is no direct heat flow from inside the appliance. This ensures a safe opening and closing of the door. However, since the door can be opened from different sides, it is best to note that the door handles are located on each side of the door.

Takšen način izvedbe in odpiranja vrat zagotavlja minimalen pomik vrat v prostor pred aparatom, kar omogoča neoviran pristop k aparatu, saj pred njim ni ovirajočih ležečih vrat.This way of opening and opening the door ensures minimal door movement in the space in front of the appliance, which enables unobstructed access to the appliance, since there are no obstructive doors in front of it.

Pojavi pa se še ena prednost pred dosedanjo izvedbo vrat. V veliko primerih ne potrebujemo celotne višine grelnega prostora, ker je velikokrat naložen pekač visok le nekaj centimetrov. Pri dosedanji izvedbi je potrebno vrata popolnoma odpreti, če želimo vstaviti pekač. Z vertikalno premičnimi vrati pa imamo v takšnih primerih dodatno možnost. Če se vrata odprejo npr. samo do polovice v višino, ustvarijo odprtino, ki je že dovolj velika za vstavljanje in odstranjevanje pekača. S takšno majhno odprtino, v primerjavi z odprtino, ki jo tvorijo enojna rotirajoča vrata, kjer se grelni prostor aparata v celoti odpre, pa pripomoremo k veliko manjši izmenjavi hladnega in toplega zraka med prostorom in grelnim prostorom aparata in s tem tudi k veliko manjšemu padcu temperature v grelnem prostoru aparata.However, there is another advantage over the previous design of the door. In many cases, we do not need the full height of the heating compartment because many times the baking tray is only a few inches high. To date, the door has to be completely opened in order to insert a baking tray. With vertically sliding doors, however, we have an additional option in such cases. If the door opens e.g. only half way up, they create an opening that is already large enough to insert and remove the baking tray. With such a small opening, compared to the opening formed by a single rotating door, where the heating space of the appliance is fully opened, we contribute to a much smaller exchange of cold and warm air between the space and the heating space of the appliance and thus to a much smaller drop. temperatures in the heating compartment of the appliance.
