Description

Odzračevanje hladilno zamrzovalnega aparataVentilation of the refrigerating freezer

Predlagani izum se nanaša na hladilni in/ali zamrzovalni aparat, prednostno gospodinjski hladilni in/ali zamrzovalni aparat, obsegajoč hladilni prostor, obdan z izoliranim ohišjem, ki ga zapirajo vrata s tesnilom za tesnjenje ob robu notranjega dela vrat, pri čemer je tesnilo pritrjeno v posebej za to zasnovanem utoru, s pomočjo katerega je omogočena izravnava tlaka med hladilnim prostorom in okolico.The present invention relates to a refrigeration and / or freezer, preferably a household refrigeration and / or freezer, comprising a cooling compartment enclosed by an insulated enclosure closed by a door with a sealing gasket at the edge of the interior of the door, the gasket being secured in specially designed groove to allow pressure to be balanced between the cooling compartment and the surrounding area.

Pri pogostejšem odpiranju vrat hladilnega aparata pride do pojava, da je sila odpiranja vrat različna, včasih tudi moteče velika. Do povečanja sile odpiranja vrat prihaja zaradi temperaturne razlike med zunanjostjo in hladilnim prostorom hladilnika pri odprtju in zaprtju vrat hladilnega prostora, ko se le-ta začne po zaprtju vrat hladiti. V takšnem primeru ob dobrem tesnjenju vrat pride v hladilnem prostoru do podtlaka. Nasprotno pa pride v času cikla, ko hladilni kompresor ne deluje, do povečanja volumna zraka, saj je takrat lahko ob primernem tesnjenju vrat sila odpiranja majhna, kar zopet ni priporočljivo. Pri slabem tesnjenju vrat ne pride do pojava povečanja sile odpiranja vrat zaradi poddaka, vendar se zaradi pretoka zraka na mestih, kjer aparat ne tesni, začne nabirati vlaga ali led, kar je po eni strani moteče, po drugi pa predstavlja neželeno izgubo energije.More frequent opening of the door of the refrigeration appliance results in the fact that the door opening force is different, sometimes even disturbingly large. Increasing the door opening force is due to the temperature difference between the outside and the cooling compartment of the refrigerator when opening and closing the cooling compartment door when it starts to cool after closing the door. In such a case, when the door is properly sealed, there is a vacuum in the cooling compartment. On the contrary, during the cycle when the refrigeration compressor is not running, the volume of the air will increase, since when the door is properly sealed, the opening force may be small, which is again not advisable. Poor door sealing does not lead to an increase in the door opening force due to the underdog, but due to the flow of air in places where the appliance is not sealed, moisture or ice begins to accumulate, which on the one hand is annoying and represents an unwanted loss of energy.

Znanih je več pristopov k reševanju zgoraj navedenih težav. Ena od znanih rešitev predlaga vgraditev ročaja, ki s pomočjo odrivnega vzvodnega mehanizma ob potegu ročaja pomaga premagati silo podtlaka in magnetno silo tesnila ob odpiranju vrat. Druga rešitev predlaga izravnavo tlaka med hladilnim prostorom in okolico, kar je mogoče doseči z vgradnjo izenačevalnega tlačnega ventila, preko katerega je hladilni prostor povezan z okolico. Na tak način je zagotovljen pretok zraka iz zunanjosti v notranjost, v nasprotni smeri pa ne, kar preprečuje iztok hladnega zraka v okolico in posledično izgubo energije. Omenjeni ventil je lahko zasnovan npr. z uležajeno kroglico v lijaku ali na drug znan način, kar pa poveča izdelovalne stroške aparata.Several approaches are known to solve the above problems. One well-known solution is to install a handle which, by means of a pull-out lever mechanism, helps to overcome the vacuum force and the magnetic force of the seal when the door is opened when the handle is pulled. Another solution proposes to compensate for the pressure between the cooling compartment and the surroundings, which can be achieved by installing an equalizing pressure valve through which the cooling compartment is connected to the surroundings. In this way, the air flow from the outside to the interior is ensured, but not in the opposite direction, which prevents the cold air from flowing into the surroundings and the consequent loss of energy. Said valve may be designed e.g. with a ball bearing in a funnel or in another known way, which in turn increases the machine's manufacturing costs.

Nekatere rešitve predvidevajo uporabo elastične membrane, razporejene na odprtini, preko katere je hladilni prostor povezan z okolico. Elastična membrana se seveda deformira v smeri podtlaka, preprečuje pa prehajanje zraka in zato je rešitev, kar se izgube energije tiče primernejša. Slabost te rešitve je, da se na sami membrani lahko nabira vlaga, ki zmrzuje in ovira elastično deformacijo membrane. Tudi elastičnost membran se z leti zmanjšuje in material stara, tako da je delovanje membran po nekaj letih vprašljivo.Some solutions involve the use of an elastic membrane arranged at an opening through which the cooling space is connected to the surroundings. The elastic membrane, of course, deforms in the direction of the pressure, but prevents the passage of air, and therefore the solution for energy loss is more appropriate. The disadvantage of this solution is that moisture can accumulate on the membrane itself, which freezes and impedes the elastic deformation of the membrane. Also, the elasticity of the membranes decreases over the years and the material ages, making the functioning of the membranes questionable after a few years.

Še nadaljnja znana rešitev predvideva, da se na tesnilu izdelajo prečne odprtine, ki povezujejo hladilni prostor z okolico. Izdelava takšnega tesnila je dražja, pomanjkljivost te rešitve pa je tudi, da se v odprtinah tesnila začne nabirati vlaga, lahko tudi led in umazanija. Takšno tesnilo je znotraj profila in v okolici odprtin težko ali celo nemogoče očistiti, kar zmanjšuje funkcionalnost.Another well-known solution is to provide that transverse openings are made on the gasket to connect the cooling space to the surroundings. It is more expensive to produce such a seal, but the disadvantage of this solution is that moisture, even ice and dirt can start to accumulate in the gasket openings. Such a seal is difficult or even impossible to clean inside the profile and around the openings, reducing functionality.

Ena od znanih rešitev, ki je primerljivo najenostavnejša, predvideva, da se na notranji površini vrat z izdelavo prečne poglobitve pod tesnilom naredi direkten prehod iz zunanjosti v notranjost. S tem je izenačevanje tlaka enostavno doseženo, vendar ima rešitev lahko nekaj slabosti, še posebej pri pokončno postavljenih hladilnih aparatih. Če se direkten prehod razporedi pod tesnilom na zgornji rob vrat, je ob primernem tesnjenju aparata to najugodneje, ker ne pride do odtekanja hladnega zraka iz aparata, izenačevanje tlaka pa je zagotovljeno. Večino pokončnih aparatov ima v spodnjem delu vgrajene tudi manjše odprtine za iztekanje nastalega kondenzata. V tem primeru je razporeditev direktnega prehoda zgoraj neprimerna, saj je s tem omogočen stalen pretok zraka iz okolice v notranjost hladilnega prostora. Zato je primerneje, da se direkten prehod razporedi v spodnjem delu vrat na stranskih vertikalah ali na spodnjem robu vrat. Največja slabost direktnega prehoda je vsekakor ta, da pri slabšanju tesnjenja vrat tekom življenjske dobe aparata, direkten prehod nima viskoznega upora pretoka zraka in omogoča dodaten stalen neoviran iztok hladnega zraka in s tem posledično izgubo energije ter nabiranje vlage in kondenzata na spodnjem zunanjem delu aparata, kar je za uporabnika moteče.One of the known solutions, which is comparatively simplest, assumes that a direct passage from the outside to the interior is made on the inner surface of the door by making a transverse recess under the seal. This makes pressure equalization easy to achieve, but the solution may have some drawbacks, especially for upright refrigerators. If a direct passage is arranged under the gasket on the upper edge of the door, the proper sealing of the appliance is most advantageous because no cold air is escaping from the appliance and pressure equalization is ensured. Most upright appliances also have smaller openings in the lower part for leaking condensate. In this case, the arrangement of the direct passage above is inappropriate since this allows a constant flow of air from the surroundings to the interior of the cooling compartment. Therefore, it is more appropriate for the direct passage to be arranged in the lower part of the door on the side verticals or on the lower edge of the door. The biggest drawback of the direct passage is, in any case, that in the case of the door sealing, during the lifetime of the appliance, the direct passage does not have a viscous resistance to the flow of air and allows for an additional continuous unobstructed outflow of cold air and consequently loss of energy and the accumulation of moisture and condensate on the lower outer part of the appliance. which is annoying for the user.

V dokumentu FR2445916 je razkrita rešitev, ki predvideva prehod zraka po daljši poti pod tesnilom. Pri tem je utor pod tesnilom zasnovan tako, da vstopna odprtina poteka prečno na tesnilo, nato zrak potuje po poglobitvi pod tesnilom po vzdolžni osi tesnila in prehaja v notranjost preko prečno na tesnilo zasnovanega izhoda, ki je znatno oddaljen od prečnega vhoda. Za preprečitev iztoka hladilnega zraka je potrebno doseči večji viskozni upor, zato je kanal indirektnega prehoda pod tesnilom relativno dolg, prednostno po celotni širini aparata. Predolg kanal pa predstavlja pomanjkljivost, saj se v dolgem utoru nabira vlaga, ki zmrzuje in dviguje tesnilo ter zamaši prehod, zaradi česar je potrebno vgraditi dodane grelne elemente.Document FR2445916 discloses a solution that provides for the passage of air over a longer path under the seal. In this case, the groove under the seal is designed so that the inlet opening is transverse to the seal, then the air travels in the recess below the seal along the longitudinal axis of the seal and passes inward through the transverse to the sealed outlet, which is substantially distant from the transverse inlet. In order to prevent the cooling air from flowing out, a higher viscous resistance is required, so the channel of indirect passage under the seal is relatively long, preferably over the entire width of the apparatus. For too long, the duct is a disadvantage as moisture accumulates in the long groove, freezing and lifting the seal and clogging the passage, which makes it necessary to install additional heating elements.

Nadalje je v dokumentu US5228314 razkrita rešitev, ki sicer obravnava postopek hlajenja hrane na način uporabe kombinacije predhodnega hlajenja hladilnega vsebnika in umetno ustvarjenega podtlaka v njem. Z integriranjem primernih premerov kanalov indirektnega prehoda pod pokrovom se da doseči dovolj velik viskozni upor pri možnem pretoku hladnega zraka. Tako se lahko tlak med notranjostjo ohlajenega vsebnika in okolico izenači, pretok zraka pa je v večji meri zaradi primerne dolžine utorov in viskoznega upora zaradi velike razlike gostot notranjega hladnega in zunanjega toplega zraka onemogočen.Further, document US5228314 discloses a solution that otherwise addresses the process of food cooling by using a combination of pre-cooling of the refrigerant container and artificially created underpressure therein. By integrating suitable diameters of the indirect passage ducts under the hood, a sufficiently high viscous resistance can be achieved in the possible flow of cold air. Thus, the pressure between the inside of the cooled container and its surroundings can be equalized, and the flow of air is largely prevented due to the adequate groove length and viscous resistance due to the large difference in the densities of the internal cold and the outside warm air.

Naloga izuma je ustvariti hladilni in/ali zamrzovalni aparat, prednostno gospodinjski hladilni in/ali zamrzovalni aparat, pri katerem so odpravljene pomanjkljivosti znanih rešitev.It is an object of the invention to provide a refrigeration and / or freezer, preferably a household refrigeration and / or freezer, which eliminates the disadvantages of known solutions.

Zastavljena naloga je po predlaganem izumu rešena tako, da je indirektni prehod v utoru pod tesnilom zasnovan na področju spodnjega levega in spodnjega desnega vogala tesnila, gledano aparat s sprednje strani. Podolgovata odprtina, ki povezuje omenjeni indirektni prehod z okolico, je zasnovana na notranjem spodnjem robnem odseku ohišja vrat s poglobitvijo ob spodnjem robu tesnila. Podolgovata odprtina, ki povezuje omenjeni indirektni prehod s hladilnim prostorom aparata, je zasnovana na notranjem navpičnem levem oziroma desnem robu vrat, s poglobitvijo ob navpičnem notranjem robu tesnila na levi oziroma desni strani vrat. Obe podolgovati odprtini sta od vogala tesnila odmaknjeni v smislu potrebnega podaljševanja indirektnega prehoda za dosego dovolj velike viskozne upornosti pretoka zraka v indirektnem prehodnem kanalu pod tesnilom.The object of the present invention is solved in such a way that the indirect passage in the groove under the seal is designed in the region of the lower left and lower right corner of the seal, viewed from the front. An elongated opening connecting said indirect passage to the surroundings is designed on the inner lower edge portion of the door housing with a recess along the lower edge of the seal. The elongated opening connecting the said indirect passage with the cooling space of the appliance is designed on the inside vertical left or right edge of the door, with a recess along the vertical inner edge of the seal on the left or right side of the door. Both elongated openings are offset from the corner of the seal in terms of the necessary extension of the indirect passage to achieve a sufficiently high viscous resistance to the air flow in the indirect passage passage below the seal.

Z optimiziranjem dolžine in prereza omenjenega indirektnega prehodnega kanala se lahko pri različnih volumnih aparatov doseže želen učinek zmanjšanja sile zaradi nastalega podtlaka kot posledice pogostejšega odpiranja vrat. Ena od prednosti takšne izvedbe leži v tem, da se sočasno z izenačevanjem tlaka preko dveh vogalnih indirektnih prehodov doseže ugoden podvojen prerez za pretok zraka pri odpiranju vrat, sočasno pa se obdrži relativno visoko viskozno upornost pretoka zraka v obeh indirektnih prehodih.By optimizing the length and cross section of said indirect passage channel, the desired effect of reducing the force due to the resulting pressure can be achieved for different volume appliances, as a result of more frequent opening of the door. One advantage of such an embodiment is that, at the same time as the equalization of pressure through two corner indirect crossings, a favorable double cross section for the air flow is obtained when the door is opened, while maintaining a relatively high viscous air flow resistance in both indirect crossings.

Naslednja od prednosti predlaganega izuma je toga lega tesnila, pod katerim je zasnovan prehod. Zaradi kotne oblike v vogalu in stalnega naseda tesnila na enega od robov je tesnilo oz. položaj le-tega veliko bolj stabilen in ne more priti do naključnega premikanja.Another advantage of the present invention is the rigid sealing position under which the passage is designed. Due to the angular shape in the corner and the constant seating of the gasket on one of the edges, the gasket or. its position is much more stable and cannot be accidentally moved.

Nadaljnja prednost takšne izvedbe odzračevanja leži v tem, da se doseže gibanje zraka v področjih spodnjih prednjih vogalov hladilnega prostora, kjer se zrak običajno ne giblje. To ugodno vpliva na nastanek in sušenje kondenzata in na konstantno razporeditev temperature v tem področju.A further advantage of such a venting arrangement is that the movement of air is achieved in the regions of the lower front corners of the cooling compartment where the air does not normally move. This has a beneficial effect on the formation and drying of the condensate and on the constant temperature distribution in the area.

Še nadaljnja prednost tovrstne izvedbe leži tudi v tem, da kadar se kondenzat pojavi v prehodnem kanalu, kondenzat zaradi lastne teže steče po kanalu navzdol v smeri proti odprtini, ki povezuje prehod z okolico. V področju izteka indirektnega prehoda v okolico se nato kondenzat zaradi višje temperature zraka posuši. Ob zelo pogostem odpiranju vrat in visoki relativni vlažnosti okoliškega zraka se lahko ustvari večja količina kondenzata v indirektnem prehodnem kanalu. Kondenzat zaradi vertikalne postavitve kanala lahko steče v zunanjost aparata. Zaradi lastne teže je omogočeno samodejno odvajanje kondenzata iz prehodnega kanala, s čimer je preprečena zamašitev kanala in morebitno nastajanje ledu na vstopni odprtini, sočasno pa se obdrži indirektni prehodni kanal.Another advantage of this embodiment is that when the condensate occurs in the passage channel, the condensate flows due down its channel down the channel towards the opening connecting the passage to the surroundings. In the area where the indirect passage to the environment expires, the condensate is then dried due to the higher air temperature. With very frequent door openings and high relative humidity of the surrounding air, a larger amount of condensate can be generated in the indirect passage channel. Condensation due to the vertical placement of the duct can flow into the exterior of the appliance. Due to its own weight, condensate is automatically discharged from the passage channel, which prevents clogging of the channel and the possible formation of ice at the inlet, while maintaining the indirect passage channel.

Zaradi inventivne postavitve vhodno izhodnih odprtin, je možno z dodatnimi oblikovnimi detajli preprečiti vstop morebitnega kondenzata v prehodni kanal. Iztekanje kondenzata, ki nastane v prehodnem kanalu, v okolico aparata, se da preprečiti z dodatnimi oblikovnimi značilnostmi tako, da se kondenzat osuši pred izlitjem v okolico aparata.Due to the inventive layout of the inlet outlet openings, it is possible to prevent any condensate from entering the passage through additional design details. The leakage of condensate formed in the passage duct into the surroundings of the apparatus can be prevented by additional design features by drying the condensate before it is discharged into the surroundings of the apparatus.

Izum je v nadaljevanju podrobneje opisan na osnovi neomejujočega izvedbenega primera in s sklicevanjem na priloženo skico, kjer kaže sl. 1 hladilno zamrzovalni stroj v tridimenzionalnem pogledu, sl. 2 delni pogled na prerez II-II s sl. 1, sl. 3 del vrat hladilno zamrzovalnega aparata v tridimenzionalnem pogledu z notranje strani, sl. 4 prerez po črti IV-IV s sl. 3, sl. 5 prerez po črti V-V s sl. 3, sl. 6 prerez po črti VI-VI s sl. 3, sl. 7 prerez po črti VII-VII s sl. 3,The invention will now be described in more detail with reference to a non-limiting embodiment and with reference to the accompanying drawing, where FIG. 1 is a three-dimensional refrigerating freezer, FIG. 2 is a partial sectional view of II-II in FIG. 1, FIG. 3 is a three-dimensional view of the interior of the refrigerator-freezer door, FIG. 4 is a cross-sectional view taken along line IV-IV of FIG. 3, FIG. 5 is a cross-sectional view taken along line V-V of FIG. 3, FIG. 6 is a cross-sectional view taken along line VI-VI of FIG. 3, FIG. 7 is a cross-sectional view taken along line VII-VII of FIG. 3,

Izum je v nadaljevanju opisan na prednostnem izvedbenem primeru pokončnega hladilnega aparata, čeprav je bistvo izuma mogoče uporabiti tudi pri drugih hladilno zamrzovalnih aparatih, na primer pri zamrzovalni skrinji.The invention is described below in a preferred embodiment of an upright refrigerating appliance, although the essence of the invention can also be applied to other refrigeration freezers, such as a freezer compartment.

Hladilno zamrzovalni aparat obsega telo 1 s hladilnim in/ali zamrzovalnim predelkom, v katerem se hrani dobrine in ki se ga da zapreti z vrati 2. Vrata 2 so s svojo notranjo steno 3 pritisnjena k pripadajoči steni 4 telesa 1, pri čemer je med steno 3 vrat 2 in steno 4 telesa 1 razporejeno tesnilo 5, ki tesni hladilni in/ali zamrzovalni predelek proti okoliškemu zraku. Omenjeno tesnilo 5 je prednostno razporejeno v kanalu 6, ki je obrnjen proti omenjeni steni 4 telesa 1 in zasnovan po celotnem obodu omenjene stene 3 vrat 2.The refrigerating freezer comprises a body 1 with a refrigerating and / or freezer compartment in which the goods are stored and which can be closed by the door 2. The door 2 is pressed with its inner wall 3 against the corresponding wall 4 of the body 1, while between the wall 3 door 2 and body wall 4 1 arranged gasket 5 which seals the cooling and / or freezer compartment against the surrounding air. Said gasket 5 is preferably disposed in a channel 6 facing the said wall 4 of the body 1 and designed along the entire circumference of said wall 3 of the door 2.

Vsaj eno vogalno območje 7 omenjenih vrat 2 je zasnovano z vsaj parom poglobitev 8; 9, ki sta medsebojno povezani s pomočjo veznega kanala 10. Pri tem je po predlaganem izumu predvideno, da je omenjeni kanal 10 globlji od kanala 6, predvidenega za sprejem tesnila 5. Dalje je po izumu predvideno, da je vsakokratna poglobitev 8; 9 zasnovana tako, da preseka omenjeni kanal 6 oz. se kanal 6 izliva v vsakokratno poglobitev 8; 9. Po prednostnem izvedbenem primeru je predvideno, da je na primer prva poglobitev 8 zasnovana v vodoravnem odseku vrat 2, medtem ko je druga poglobitev 9 zasnovana v navpičnem odseku vrat 2. Pri predstavljenem izvedbenem primeru je omenjena poglobitev 8; 9, gledano v ravnini vrat 2, zasnovana kot pravokotnik. Mogoče je tudi, da je vsaj ena od sten 11, 12, 13 vsaj ene poglobitve 8; 9 zasnovana pod kotom glede na vzdolžni in/ali prečni potek kanala 6, tako da je prostorsko nagnjena v smeri proti notranjosti hladilnega predelka. Omenjena poglobitev 8; 9, gledano v ravnini vrat 2, lahko v splošnem zavzema obliko paralelograma, na primer romba, romboida, trapeza in podobno. Na tak način se doseže, da kondenzat, ki se nabira v območju nad poglobitvijo 9 v navpičnem odseku vrat 2 in v območju vstopa v poglobitev 9, ne teče neposredno v omenjeni vezni kanal 10, temveč steče po nagnjeni spodnji stranski steni 11 nazaj v hladilni predelek in navzdol do vzdolžnega roba tesnila 5 na spodnjem vodoravnem robu vrat 2, kjer tesnilo 5 tesni po celotni širini vrat 2. Zaradi tega kondenzat ne more iztekati pod tesnilom 5 v okolico, čeprav je v tem območju vezni kanal 10 povezan z okolico.At least one corner area 7 of said door 2 is designed with at least a pair of recesses 8; 9, which are interconnected by means of a connecting channel 10. According to the present invention, it is provided that said channel 10 is deeper than the channel 6 intended to receive the seal 5. Further, according to the invention, it is provided that each recess 8; 9 is designed to intersect said channel 6 or. the channel 6 flows into the respective recess 8; 9. According to a preferred embodiment, it is provided, for example, that the first recess 8 is formed in the horizontal section of the door 2, while the second recess 9 is designed in the vertical section of the door 2. In the presented embodiment, said recess 8; 9, viewed in the plane of door 2, designed as a rectangle. It may also be that at least one of the walls 11, 12, 13 has at least one recess 8; 9 is angled with respect to the longitudinal and / or transverse course of the duct 6, so that it is inclined spatially toward the interior of the cooling compartment. The said recess 8; 9, viewed in the plane of door 2, can generally take the form of a parallelogram, such as a rhombus, rhombus, trapezoid, and the like. In this way, it is achieved that the condensate that accumulates in the area above the recess 9 in the vertical section of the door 2 and in the area entering the recess 9 does not flow directly into said connecting channel 10, but flows down the inclined lower side wall 11 back into the cooling compartment and down to the longitudinal edge of gasket 5 at the lower horizontal edge of door 2, where gasket 5 seals the entire width of door 2. As a result, condensate cannot flow out of gasket 5 into the surrounding area, although in this area the connecting channel 10 is connected to the environment.

Kondenzat, ki ob pogostem odpiranju vrat 2 nastaja pod tesnilom 5 v navpičnem odseku 10' veznega kanala 10 teče v spodnji vodoravni odsek 10 veznega kanala 10 in dalje proti poglobitvi 8. Ker je temperatura zraka v tem območju že višja, se začne kondenzat sušiti. Ob morebitni večji količini nastalega kondenzata je smiselna uvedba dodatnih oblikovnih značilnosti v smislu integriranja vsebnikov na notranji površini vrat, ki zadržijo večjo količino kondenzata, da lahko le-ta izhlapi, še preden steče v okolico v področje dna aparata in na tla, na katerih aparat stoji. Eden od mogočih načinov je, da se poglobitev 8 dodatno poglobi in z negativnim kotom stranic ustvari vsebnik, ki ujame določeno količino kondenzata, da lahko le-ta izhlapi, preden se izlije v okolico aparata. Izbiroma se lahko tudi dodatno narebri dno in stene vodoravnega odseka 10 veznega kanala 10, s čimer se del kondenzata še dodamo zadrži.The condensate which, upon frequent opening of the door 2, forms under the seal 5 in the vertical section 10 'of the conduit 10 flows into the lower horizontal section 10 of the conduit 10 and further towards the recess 8. As the air temperature in the area is already higher, the condensate begins to dry. With the increased amount of condensate produced, it makes sense to introduce additional design features in terms of integrating the containers on the inner surface of the door, which retain a large amount of condensate so that it can evaporate before it enters the area into the bottom of the appliance and to the floors on which the appliance standing. One possible way is to further deepen the recess 8 and create a container that catches a certain amount of condensate with a negative side angle so that it can evaporate before it flows into the surroundings of the apparatus. Optionally, the bottom and walls of the horizontal section 10 of the connection channel 10 may be further grooved, thereby retaining a portion of the condensate.

Seveda so možne tudi druge izvedbe z veznim kanalom, ki so na osnovi opisanega izuma povsem očitne povprečnemu strokovnjaku na tem področju. Ena od mogočih izvedb predvideva, da sta poglobitvi vsakokratno zasnovani na navpičnem odseku tesnila na levi in/ali na desni strani vrat in prednostno na spodnji polovici vrat.Of course, other embodiments with a conduit are also possible, which, based on the present invention, are quite obvious to one of ordinary skill in the art. One of the possible embodiments assumes that the recesses are each based on a vertical section of gasket on the left and / or right side of the door and preferably on the lower half of the door.
