Description
HLADILNO-ZAMRZOVALNI APARAT Z NAPRAVO, KI OLAJŠA ODPIRANJE VRAT [00011 Predlagani izum se nanaša na hladilno-zamrzovalni aparat, obsegajoč vsaj en toplotno izoliran predelek za sprejem dobrin, ki je obdan z ohišjem in ki se ga da zapreti z vrati ali s pokrovom, pri čemer ohišje obsega obodne stene in hrbtno steno, in napravo, ki olajša odpiranje vrat hladilno-zamrzovalnega aparata.[00011 The present invention relates to a refrigerating-freezing apparatus comprising at least one heat-insulated compartment for receiving goods, which is enclosed by a housing and which can be closed by a door or a lid, the enclosure comprising a perimeter wall and a back wall, and a device facilitating the opening of the refrigerator-freezer door.
[0002] Za ustvarjanje temperaturne razlike med toplotno izoliranim predelkom za sprejem dobrin in okoliško atmosfero je predviden hladilni sistem, na primer kompresorski ali absorpcijski hladilni sistem ali podobno. Temperatura živil in zraka v omenjenem toplotno izoliranem predelku se zaradi cikličnega delovanja hladilnega sistema in/ali občasnega odpiranja vrat oziroma predelka spreminja, kar povzroča nihanje tlaka v toplotno izoliranem prostoru in posledično izmenjavo zraka z okoliško atmosfero. Pri vsakem odpiranju vrat oz. pokrova predelka se del zraka v toplotno izoliranem predelku zamenja s toplejšim iz okolice. Po zaprtju vrat oz. pokrova predelka se zaradi ohlajanja omenjenega toplejšega zraka ustvari podtlak, ki sesa topel in vlažen zrak iz okolice v notranjost hladilno-zamrzovalnega aparata oz. omenjenega predelka. Odvečna vlaga iz zraka se v obliki rose ali sreža odlaga na hladnih površinah, se tam kopiči in povzroči zaledenitev. Glede na tesnost ohišja ali tesnilnih površin med vrati oz. pokrovom in predelkom lahko izenačenje tlaka med okolico in toplotno izoliranim predelkom traja dalj časa. Omenjeni podtlak močno oteži ali celo začasno onemogoči odpiranje vrat oz. pokrova predelka. Za lažje odpiranje vrat oz. pokrova se uporablja različne mehanske sisteme in povezovalne odprtine z okoliško atmosfero, s čimer se dak v notranjosti hladilno-zamrzovalnega aparata oz. predelka hitreje izenači z okoliškim tlakom. Slaba stran tovrstnih rešitev je kopičenje sreža zlasti okoli povezovalne odprtine, na notranjih površinah aparata in na živilih, ki so blizu omenjene odprtine.[0002] A cooling system, such as a compressor or absorption cooling system, or the like, is provided to create a temperature difference between a thermally insulated compartment for receiving goods and the surrounding atmosphere. The temperature of the food and air in said thermally insulated compartment changes due to the cyclical operation of the refrigeration system and / or the occasional opening of the door or compartment, which causes fluctuations in the pressure in the thermally insulated space and the consequent exchange of air with the surrounding atmosphere. Each time the door is opened, the compartment cover is replaced by a portion of the air in the thermally insulated compartment with a warmer compartment. After closing the door or. Due to the cooling of said warmer air, a compartment cover is created which sucks the warm and moist air from the surroundings into the interior of the refrigerator and freezer. said compartment. Excess moisture from the air is deposited in the form of dew or dross on cold surfaces, accumulates there and causes icing. Depending on the tightness of the housing or the sealing surfaces between the door or the door. the lid and compartment, the pressure equalization between the surroundings and the thermally insulated compartment may take a long time. This underpressure makes it difficult or even temporarily impossible to open the door or door. compartment cover. For easier opening of doors or doors. different mechanical systems and connecting openings with the surrounding atmosphere are used, thus leaving the inside of the refrigerator-freezer or the compartment is faster equated to ambient pressure. The disadvantage of such solutions is the accumulation of frost, especially around the connection opening, on the interior surfaces of the appliance and on foods close to the opening.
Za odpravo zgoraj navedenih težav so razkrite rešitve, ki predvidevajo uporabo posebne razvlaževalne enote kot del hladilnega sistema, ali obnovljivo sušilno sredstvo v smislu molekularnega sita, ki je nameščeno v notranjosti hladilno-zamrzovalnega aparata ali v omenjeni povezovalni odprtini. Kadar je sušilno sredstvo nameščeno v notranjosti aparata, je posledično občutno zmanjšan uporabni prostor pa tudi srez, ki nastaja okoli povezovalne odprtine se odstrani le v manjši meri. Poleg tega mora uporabnik hladilno-zamrzovalnega aparata omenjeno sušilno sredstvo po nasičenju z vlago odstraniti in dati v regeneracijo ali namestiti novega, če želi preprečiti nastajanje sreza v hladilno-zamrzovalnem aparatu.To overcome the above problems, solutions disclosing the use of a special dehumidifier as part of a cooling system or a renewable desiccant in the sense of a molecular sieve placed inside the freezer or in the said connection opening are disclosed. When the desiccant is installed inside the appliance, the resulting usable space is significantly reduced, and the incision around the connection opening is only slightly removed. In addition, after drying the moisture-freezer, the user of the refrigerator-freezer must remove and put it into regeneration or install a new one in order to prevent the formation of a cut in the refrigerator-freezer.
Izvedbe, ki imajo sušilno sredstvo v povezovalni odprtini, sicer znatno zmanjšajo vstop vlage v aparat oz. predelek, vendar je zamenjava ali regeneracija tovrstnega sušilnega sredstva dokaj otežena. Namestitev v vezno odprtino lokalno zmanjša toplotno izolacijo ohišja aparata ali pa zmanjša uporabno prostornino le-tega, [0003] Naloga izuma je ustvariti napravo za izenačenje tlaka pri hladilno-zamrzovalnem aparatu, s katero so odpravljene pomanjkljivosti znanih rešitev.Designs that have a desiccant in the connecting hole, otherwise significantly reduce moisture entry into the appliance or. compartment, but the replacement or regeneration of such a drying agent is quite difficult. Installation in the connection opening locally reduces the thermal insulation of the apparatus casing or reduces its usable volume, [0003] The object of the invention is to create a pressure equalization device for a refrigerating-freezer apparatus, which eliminates the disadvantages of known solutions.
[0004] Zastavljena naloga je po predlaganem izumu rešena z značilnostmi, podanimi značilnostnem delu 1. patentnega zahtevka. Podrobnosti izuma so razkrite v pripadajočih podzahtevkih.[0004] The object of the present invention is solved by the features given in the characteristic part of claim 1. Details of the invention are disclosed in the corresponding sub-claims.
[0005] Izum je v nadaljevanju podrobneje predstavljen na osnovi neomejujočega izvedbenega primera in s sklicevanjem na priloženih skic, kjer kaže sl. 1 poenostavljen prikaz hladilno-zamrzovalnega aparata, sl. 2 napravo za izenačenje tlaka po izumu v vzdolžnem prerezu, sl. 3 vezni kanal v tridimenzionalnem pogledu, in sl. 4 napravo za izenačenje tlaka v tridimenzionalnem pogledu.[0005] The invention is hereinafter described in more detail on the basis of a non-limiting embodiment and with reference to the accompanying drawings, where FIG. 1 is a simplified view of a refrigerator-freezer, FIG. 2 is a longitudinal cross-sectional view of the pressure equalization device of FIG. 3 shows a three-dimensional connection channel, and FIG. 4 a device for equalizing pressure in three-dimensional view.
[0006] Hladilno-zamrzovalni aparat 1 obsega vsaj en toplotno izoliran predelek 2 za sprejem dobrin, ki je obdan z ohišjem 3 in ki se ga da zapreti z vrati 4 ali pokrovom. Omenjena vrata 4 so pri tem lahko zasnovana bodisi kot pokončna vrata ali kot ležeča vrata, odvisno od izvedbe hladilno-zamrzovalnega aparata 1. V nadaljevanje je izum opisan na izvedbenem primeru pokončnega aparata 1.[0006] The refrigerator-freezer 1 comprises at least one thermally insulated compartment for receiving goods, which is enclosed by a housing 3 and which can be closed by a door 4 or a lid. Said door 4 may be designed as either an upright door or a recessed door, depending on the embodiment of the refrigerator-freezer 1. The invention will now be described in the following embodiment of the upright apparatus 1.
[0007] Omenjeno ohišje 3 obsega stranski steni, spodnjo in zgornjo steno in hrbtno steno 5. Ob zunanji strani hrbtne stene 5 in v spodnjem območju le-te je razporejen po sebi znan kondenzator 6. Da bi se preprečilo nastanek podtlaka v predelku 2, je na zunanji strani ene od sten ohišja 3 ali vrat 4, v predstavljenem izvedbenem primeru pa na zunanji strani hrbtne stene 5 razporejena odstranljiva naprava 7 za izenačenje tlaka v predelku 2 oz. hladilno-zamrzovalnem aparatu 1. Omenjena naprava 7 je prednostno razporejena v območju neposredno nad * · kondenzatorjem 6 hladilno-zamrzovalnega aparata 1. Omenjena naprava 7 za izenačenje tlaka je z notranjostjo hladilno-zamrzovalnega aparata 1 oz. z notranjostjo predelka 2 povezana s pomočjo veznega kanala 8, ki je zasnovan v omenjeni hrbtni steni 5. Vezni kanal 8 pri tem poteka nagnjeno navzdol v smeri iz notranjosti predelka 2 proti okolici. V notranjosti naprave 7 za izenačenje tlaka je razporejeno sušilno sredstvo 9, na primer v obliki molekularnega sita.[0007] Said housing 3 comprises a side wall, a lower and an upper wall, and a back wall 5. A known capacitor 6 is arranged along the outside of the back wall 5 and in the lower region thereof, in order to prevent underpressure in compartment 2, there is on the outside of one of the walls of the housing 3 or the door 4, and in the embodiment shown, a removable device 7 for equalizing the pressure in the compartment 2 or 2 is arranged on the outside of the back wall 5. the freezer 1. The aforementioned device 7 is preferably arranged in the area directly above the condenser 6 of the refrigeration freezer 1. The said pressure equalizing device 7 is with the interior of the freezer 1 or. connected to the interior of compartment 2 by means of a connecting channel 8, which is designed in said back wall 5. The connecting channel 8 is then inclined downwards from the interior of compartment 2 towards the surroundings. A drying agent 9, for example in the form of a molecular sieve, is arranged inside the pressure equalizer 7.
[0008] Omenjena naprava 7 za izenačenje tlaka je zasnovana kot vsebnik 10, obsegajoč cevni nastavek 11, ki je tesno vstavljiv v omenjeni vezni kanal 8. Omenjeni cevni nastavek 11 poteka iz vsebnika 10 s približno enako poševnino kot vezni kanal 8. Slednji je na zunanji strani hrbtne stene opremljen s prirobnico 12, ki je predvidena za pritrditev naprave 7 za izenačenje tlaka. Omenjena naprava 7 je z omenjeno prirobnico 12 povezana bodisi oblikosklepno, na primer na način zaskoka, in/ali silosklepno, na primer s pomočjo vsaj enega vijačnega sredstva.Said pressure equalization device 7 is designed as a container 10, comprising a tubular nozzle 11 that is tightly inserted into said connecting channel 8. Said tubular nozzle 11 extends from the container 10 with approximately the same obliquity as the connecting channel 8. The latter is at the outer side of the back wall provided with a flange 12 which is provided for attaching a pressure equalization device 7. Said device 7 is connected to said flange 12 either in a locking manner, for example by snapping, and / or in a silo, for example by means of at least one screw means.
V ta namen je vsebnik 10 v območju povezave s cevnim nastavkom 11 opremljen s prirobnico 13, ki obsega bodisi nasprotna zaskočna sredstva kot omenjena prirobnica 12 veznega kanala 8 in/ali vsaj eno skoznjo luknjo 13a za sprejem omenjenega vijačnega sredstva. Dalje je vsaj ena stena in/ali dno 14 vsebnika 10 zasnovano z vsaj eno, prednostno z množico skoznjih lukenj 15 za pretok zraka iz okolice v notranjost predelka 2. Skupna površina skoznjih lukenj je tolikšna, da omogoča dober pretok zraka in s tem hitro izenačevanje tlakov med notranjostjo hladilnozamrzovalnega aparata 1 oz. predelkom 2 in okoliško atmosfero.For this purpose, the container 10 is provided in the area of connection with the tube nozzle 11 with a flange 13 comprising either counter-locking means such as said flange 12 of the connecting channel 8 and / or at least one through hole 13a for receiving said screw means. Further, at least one wall and / or bottom 14 of the container 10 is designed with at least one, preferably with a plurality of through holes 15 for the flow of air from the environment into the interior of the compartment 2. The total surface of the through holes is such that it allows good air flow and thus quick equalization pressures between the inside of the refrigerating freezer 1 oz. compartment 2 and the surrounding atmosphere.
[0009] Omenjeni vsebnik 10 je lahko izdelan v enem kosu za enkratno uporabo, pri čemer se ga po izrabi sušilnega sredstva 9 odstrani in zavrže. V alternativnem izvedbenem primeru je omenjeni vsebnik 10 zasnovan s pokrovom 16, ki zapira vsebnik 10 na nasprotni strani dna 14.[0009] Said container 10 may be made in a single disposable piece and is removed and discarded after use of the drying agent 9. In an alternative embodiment, said container 10 is designed with a lid 16 that closes the container 10 on the opposite side of the bottom 14.
V tem primeru se da izrabljeno sušilno sredstvo 9 odstraniti in nadomestiti z novim. Omenjeno sušilno sredstvo 9 je lahko v obliki granulata ali monolitnega oblikovanca, ki ga sprejme vsebnik 10. V vsakem primeru pa je vsakokratna omenjena skoznja luknja 15 manjša od izmere granulata oz. posameznega zrna sušilnega sredstva 9, s čimer se prepreči padanje delcev sušilnega sredstva 9 skozi luknje 15. Omenjeni vsebnik 10 je lahko izdelan iz materiala, ki je odporen proti visokim temperaturam, s čimer je omogočena regeneracija sušilnega sredstva 9 brez odpiranja, na primer v peči. Poleg tega je vsebnik 10 lahko izdelan iz prosojnega materiala, zaradi česar se dokaj hitro vidi, ali je sušilno sredstvo 9 že izrabljeno oz. ali je potrebna regeneracija le-tega. Za dodatno izboljšanje ugotavljanja izrabe sušilnega sredstva 9 je predvideno, da je sušilnemu sredstvu 9 primešan pigment, ki glede na stopnjo vlage oz. zasičenost z vlago spremeni barvo.In this case, the spent drying agent 9 can be removed and replaced with a new one. Said desiccant 9 may be in the form of a granulate or a monolithic mold received by the container 10. In each case, however, the said through hole 15 is smaller than the dimension of the granulate or. individual grain of the drying agent 9, thereby preventing the drying agent particles 9 from falling through the holes 15. Said container 10 may be made of a material that is resistant to high temperatures, thereby allowing the drying agent 9 to be regenerated without opening, for example in a furnace . In addition, the container 10 may be made of a translucent material, which makes it fairly quickly apparent whether the drying agent 9 is already worn out. whether regeneration is required. In order to further improve the determination of the utilization of the drying agent 9, it is envisaged that the drying agent 9 is admixed with a pigment which, depending on the degree of moisture or moisture content. moisture saturation changes color.
[00010] Omenjeni vezni kanal 8 in omenjeni cevni nastavek 11 tvorita v sestavljenem stanju tesen ujem, s čimer je preprečeno, da bi zrak iz okolice prehajal v hladilno-zamrzovalni aparat 1 oz. predelek 2 kjerkoli drugje, kot skozi skoznje luknje 15 in sušilno sredstvo 9. K omenjenemu tesnemu ujemu dodatno prispeva omenjena oblikosklepna zaskočna povezava med prirobnico 12 veznega kanala 8 in prirobnico 13 vsebnika 10. V ta namen je prirobnica 12 v območju vstopa cevnega nastavka 11 zasnovana z vsaj enim zobom 17, ki zgrabi za ustrezno spodrezan rob 18 prirobnice 13.[00010] Said connecting channel 8 and said tube nozzle 11 form a tight fit in the composite state, preventing air from flowing from the surrounding area into the freezer 1 or 2. compartment 2 anywhere other than through holes 15 and desiccant 9. In addition to said tight match, said locking connection between the flange 12 of the connecting channel 8 and the flange 13 of the container 10 contributes to this. with at least one tooth 17 that grabs the flange edge 18 of the flange 13 accordingly.
[00011] Zaradi tlačnih razlik, ki nastanejo kot posledica sprememb temperatur pri cikličnem delovanju hladilnega sistema ali odpiranja vrat/pokrova, teče zrak iz okolice v notranjost aparata ali obratno. Zrak potuje skozi sušilno sredstvo 9 v vsebniku 10, ki je razporejen na zunanji strani aparata 1, prednostno nad kondenzatorjem 6. Pri vstopu v aparat 1, sušilno sredstvo zadrži molekule vode, v aparat pa nadaljuje pot suh zrak. V obratnem primeru, ko suh zrak teče iz zamrzovalnika, prevzame na svoji poti molekule vode iz sušilnega sredstva in jih odvede v okolico. Ker je vsebnik 10 s sušilnim sredstvom 9 razporejen neposredno nad kondenzatorjem 6 oz. v njegovi neposredni bližini, k regeneraciji sušilne kapacitete adsorbenta pripomore tudi naravna konvekcija toplote. Če je v okoliški atmosferi prisotna izjemno visoka količina vlage, je kapaciteta sušilnega sredstva 9 lahko premajhna za dolgotrajno učinkovitost. V takih primerih se lahko sušilno sredstvo 9 regenerira s sušenjem pri ustrezni temperaturi ali zamenja z novim.[00011] Due to pressure differences resulting from temperature changes during the cyclic operation of the refrigeration system or the opening of the door / lid, air flows from the surroundings to the interior of the appliance or vice versa. The air travels through the desiccant 9 in the container 10 disposed on the outside of the appliance 1, preferably above the condenser 6. Upon entering the appliance 1, the desiccant retains water molecules and continues the path of dry air into the appliance. In the opposite case, when dry air flows from the freezer, it takes in its paths molecules of water from the desiccant and takes them to the surroundings. Because the container 10 with the drying agent 9 is disposed directly above the condenser 6 or. in its immediate vicinity, natural convection of heat contributes to the regeneration of the drying capacity of the adsorbent. If extremely high humidity is present in the surrounding atmosphere, the capacity of the drying agent 9 may be too small for long-term efficiency. In such cases, the drying agent 9 may be regenerated by drying at the appropriate temperature or replaced with a new one.
[00012] Ena od nadaljnjih prednosti zunanje namestitve naprave 7 za izenačenje tlaka po izumu leži tudi v tem, da ne zmanjšuje uporabnega prostora v zamrzovalniku. Poleg tega se omenjeno napravo 7 lahko servisno vgradi v vsak starejši hladilno-zamrzovalni aparat, kjer tovrstna naprava ni bila predvidena. S tem se zmanjša hitrost in količino nabiranja sreža na uparjalnih površinah in omogoča lažje odpiranje vrat/pokrova. Pri sanaciji obstoječih aparatov se skozi izolacijo na ustreznem mestu izvrta skoznjo luknjo, v katero se vstavi vezni kanal 8. V prirobnico 12 veznega kanala 8 se s pomočjo roba 18 zaskoči prirobnica 13 vsebnika 10 in po potrebi dodatno pritrdi z vijakoma.[00012] One of the further advantages of the external installation of the pressure equalization device 7 according to the invention also lies in the fact that it does not reduce the usable space in the freezer. In addition, said device 7 can be serviced in any older refrigerator-freezer, where such device was not intended. This reduces the speed and amount of fouling on the evaporation surfaces and makes it easier to open the door / lid. In the rehabilitation of existing appliances, a hole is inserted through the insulation at a suitable location through which a connecting channel 8 is inserted. The flange 12 of the connecting channel 8 is secured by means of the edge 18 to the flange 13 of the container 10 and further secured by screws.
[00013] Po predlaganem izumu je tudi mogoče, da je naprava 7 za izenačenje tlaka v hladilno-zamrzovalnem aparatu 1 razporejena na ali v katerikoli drugi steni ohišja 3 ali v vratih 3, ne le na hrbtni steni 5. Poleg tega je omenjena naprava 7 lahko razporejena zunaj ali znotraj hladilno-zamrzovalnega aparata 1. Po eni od mogočih izvedb je predvideno, da je naprava 7 zasnovana v ročaju hladilno-zamrzovalnega aparata 1, kar uporabniku močno olajša dostop do[00013] According to the present invention, it is also possible that the pressure equalizing device 7 in the freezer 1 is arranged on or in any other housing wall 3 or door 3, not only on the back wall 5. In addition, said device 7 can be arranged outside or inside the freezer 1. According to one of the possible embodiments, it is contemplated that the device 7 is designed in the handle of the freezer 1, which greatly facilitates the user access to
naprave 7 za izenačenje tlaka in rokovanje z njo.devices for pressure equalization and handling.
