Description
Hladilni in/ali zamrzovalni aparatRefrigerator and/or freezer
Predmet izumaThe subject of the invention
Predmet izuma je hladilni in/ali zamrzovalni aparat, prednostno gospodinjski hladilni in/ali zamrzovalni aparat, ki obsega vsaj eno celico z vsaj enim prostorom za shranjevanje živil pod ali nad temperaturo ledišča, pri čemer je kroženje hladnega zraka v omenjenem prostoru izvedeno s pomočjo vsaj enega ventilatorja.The subject of the invention is a refrigerating and/or freezing appliance, preferably a household refrigerating and/or freezing appliance, which comprises at least one cell with at least one space for storing food below or above the freezing temperature, whereby the circulation of cold air in said space is carried out with the help of at least one fan.
Tehnični problemTechnical problem
Tehnični problem je, kako zasnovati hladilni in/ali zamrzovalni aparat, prednostno gospodinjski hladilni in/ali zamrzovalni aparat, da bo hrup, kije posledica delovanja ventilatorja, odpravljen ali vsaj zmanjšan do take mere, da za uporabnika ne bo moteč.The technical problem is how to design a refrigerating and/or freezing appliance, preferably a household refrigerating and/or freezing appliance, so that the noise resulting from the operation of the fan is eliminated or at least reduced to such an extent that it is not disturbing for the user.
Stanje tehnikeState of the art
Hladilni in/ali zamrzovalni aparat, prednostno gospodinjski hladilni in/ali zamrzovalni aparat, obsega ohišje z odprtino na sprednji strani, ki omogoča vlaganje živil v aparat in jemanje hlajenih živil iz aparata ter je zaprta z vrati. Hladilni sistem, ki je razporejen v gospodinjskem aparatu in omogoča hlajenje živil, obsega kompresor, ki dovaja delo v hladilni sistem, kondenzator, ki oddaja toploto v okolico, in uparjalnik, ki odvzema toploto iz notranjosti hladilnega aparata. Zrak ob uparjalniku se ohlaja in se zaradi povečane gostote spušča proti dnu notranjosti gospodinjskega aparata. Zaradi stalnega dotekanja hladnega zraka v spodnji del gospodinjskega aparata, je spodnji del hladnejši od zgornjega dela. To privede do razlik v temperaturi med zgornjim in spodnjim delom notranjega prostora gospodinjskega aparata, kar pa ni zaželeno.A refrigerating and/or freezing appliance, preferably a household refrigerating and/or freezing appliance, comprises a housing with an opening on the front, which enables food to be placed in the appliance and cooled food to be taken from the appliance, and is closed with a door. The refrigeration system, which is arranged in a household appliance and enables food to be cooled, comprises a compressor that supplies work to the refrigeration system, a condenser that emits heat to the surroundings, and an evaporator that removes heat from inside the refrigerator. The air near the evaporator cools down and, due to the increased density, descends towards the bottom of the interior of the household appliance. Due to the constant flow of cold air into the lower part of the household appliance, the lower part is colder than the upper part. This leads to differences in temperature between the upper and lower parts of the interior of the household appliance, which is not desirable.
Da se doseže čim bolj enaka temperature znotraj celotnega prostora gospodinjskega aparata, je v notranjosti prostora običajno razporejen vsaj en ventilator, ki ustvarja prisilno gibanje hladnega zraka. Ventilator je razporejen v zaščitnem ohišju, ki uporabniku preprečuje dostop do njega, še zlasti do vrteče se vetrnice in električnih delov. Hkrati mora biti ohišje ventilatorja zasnovano tako, da je kroženje hladnega zraka učinkovito.In order to achieve as uniform a temperature as possible within the entire room of the household appliance, at least one fan is usually arranged inside the room, which creates a forced movement of cold air. The fan is arranged in a protective housing that prevents the user from accessing it, especially the rotating windmill and electrical parts. At the same time, the fan housing must be designed in such a way that the circulation of cold air is efficient.
Ventilator je vpet v ohišju ventilatorja in skupaj tvorita ventilatorski sklop, ki je togo pritrjen na ohišje gospodinjskega aparata, npr. z vijakom. Predvsem zaradi vrtenja vetrnice ventilatorja nastajajo vibracije, ki se iz ventilatorja prenašajo na ohišje ventilatorja in nato naprej na stene gospodinjskega aparata, kar povzroča moteč hrup. Z vgradnjo vibroizolacijskega materiala na mesto, kjer je ventilator vpet v ohišje ventilatorja, je prenos vibracij sicer zmanjšan, vendar ne v taki meri, da ne bi povzročal motečega hrupa. Togost elementov vibroizolacijskega materiala mora namreč ostati dovolj velika, daje kljub prenosu teže in vibracij še vedno zagotovljena tudi zadovoljiva soosnost vetrnice in difuzorja ventilatorja, ki je del omenjenega ohišja.The fan is clamped in the fan housing and together they form a fan assembly that is rigidly attached to the housing of the household appliance, e.g. with a screw. Mainly due to the rotation of the fan blade, vibrations are created, which are transmitted from the fan to the fan housing and then on to the walls of the household appliance, which causes annoying noise. By installing vibration isolation material in the place where the fan is attached to the fan housing, the transmission of vibrations is reduced, but not to such an extent that it would not cause disturbing noise. The stiffness of the elements of the vibration isolation material must remain sufficiently high, so that, despite the transfer of weight and vibrations, a satisfactory alignment of the wind turbine and the diffuser of the fan, which is part of the aforementioned housing, is still ensured.
Vibracije se iz ohišja ventilatorja prenašajo na notranjo steno ohišja aparata na vseh njunih stičnih mestih, še zlasti na mestu pritrditve ohišja ventilatorja na ohišje aparata. Ventilatorski sklop je v notranjosti gospodinjskega aparata razporejen na mestu, ki je z energetskega stališča in stališča uporabnika aparata najbolj ugodno. Da je izguba uporabnega prostora za namestitev oz. manipulacijo z živili čim manjša, je to običajno na steni oziroma v neposredni bližini vrhnjega dela zadnje stene notranjosti aparata. Se posebej se pokaže ugodno mesto v enem od vogalov, npr. med zadnjo in zgornjo steno in/ali eno izmed stranskih sten. Zaradi toge pritrditve ventilatorskega sklopa na ohišje gospodinjskega aparata, se vibracije ohišja ventilatorja prenašajo na ohišje gospodinjskega aparata. Zaradi relativno toge strukture in nizke gostote ohišja gospodinjskega aparata se te vibracije iz notranjosti ohišja gospodinjskega aparata prenašajo na zunanjo stran ohišja gospodinjskega aparata in se pri tem celo ojačijo, kar se odraža v prekomernem hrupu.Vibrations are transmitted from the fan housing to the inner wall of the appliance housing at all their points of contact, especially at the point of attachment of the fan housing to the appliance housing. The fan assembly is arranged inside the household appliance in a place that is the most favorable from the point of view of energy consumption and the point of view of the user of the appliance. That the loss of usable space for installation or manipulation of food as little as possible, this is usually on the wall or in the immediate vicinity of the upper part of the rear wall of the interior of the appliance. A favorable spot in one of the corners is especially evident, e.g. between the back and top walls and/or one of the side walls. Due to the rigid attachment of the fan assembly to the housing of the household appliance, the vibrations of the fan housing are transmitted to the housing of the household appliance. Due to the relatively rigid structure and low density of the housing of the household appliance, these vibrations from the inside of the housing of the household appliance are transmitted to the outside of the housing of the household appliance and are even amplified in the process, which is reflected in excessive noise.
Prenos vibracij na stene aparata se lahko zmanjša z namestitvijo vihro izolacijskega materiala med ohišjem ventilatorja in notranjo steno aparata. Zmanjšanje prenosa vibracij na ohišje se lahko zmanjša z namestitvijo vibroizolacijskega materiala velike debeline med ohišje ventilatorja in notranjo steno ohišja, kar predstavlja izgubo delovnega prostora, ali izbiro vibroizolacijskega materiala z visoko dušilno karakteristiko, kar za aparat opisane vrste ni ekonomsko učinkovito.The transmission of vibrations to the walls of the appliance can be reduced by installing wind insulation material between the fan housing and the inner wall of the appliance. The reduction of vibration transmission to the housing can be reduced by installing a vibration-isolating material of great thickness between the fan housing and the inner wall of the housing, which represents a loss of working space, or by choosing a vibration-isolation material with a high damping characteristic, which is not economically efficient for the device of the described type.
Rešitev tehničnega problemaSolving a technical problem
Tehnični problem je rešen s hladilnim in/ali zamrzovalnim aparatom, prednostno z gospodinjskim hladilnim in/ali zamrzovalnim aparatom, z značilnostmi, kot so opredeljene v prvem patentnem zahtevku. Nadaljnje značilnosti so opredeljene v odvisnih zahtevkih.The technical problem is solved with a cooling and/or freezing device, preferably a household cooling and/or freezing device, with features as defined in the first patent claim. Further features are defined in the dependent claims.
Hladilni in/ali zamrzovalni aparat, prednostno gospodinjski hladilni in/ali zamrzovalni aparat, obsega ohišje z odprtino; vrata, ki zapirajo odprtino in skupaj z ohišjem obdajajo vsaj eno celico z vsaj enim prostorom za shranjevanje živil pod ali nad temperaturo ledišča; v celici razporejen vsaj en ventilatorski sklop za kroženje hladnega zraka znotraj celice, kateri ventilatorski sklop obsega ventilator z vetrnico in ohišje ventilatorja; pri čemer je ventilatorski sklop pritrjen na ohišje omenjenega aparata preko nosilca ventilatorskega sklopa, ki izkazuje pritrdilni del in vsaj eni nosilni krak, kije razporejen na pritrdilnem delu tako, da v montiranem stanju sega v notranjost celice in skupaj s pritrdilnim delom tvori prostor za sprejem ventilatorskega sklopa, pri čemer omenjeni nosilec ventilatorskega sklopa in/ali vsaj ena od njegovih pritrditev na ohišje aparata ali ohišje ventilatorja izkazuje vibroizolacijske lastnosti.A refrigerator and/or freezer, preferably a household refrigerator and/or freezer, comprises a housing with an opening; a door that closes the opening and, together with the casing, encloses at least one cell with at least one space for storing food below or above freezing temperature; at least one fan assembly arranged in the cell for circulating cold air within the cell, which fan assembly comprises a fan with a wind vane and a fan housing; wherein the fan assembly is attached to the housing of the mentioned apparatus via the support of the fan assembly, which shows a fastening part and at least one supporting arm, which is arranged on the fastening part in such a way that in the assembled state it reaches inside the cell and together with the fastening part forms a space for receiving the fan of the assembly, wherein said support of the fan assembly and/or at least one of its attachments to the device housing or the fan housing exhibits vibration isolation properties.
Prednostno je nosilni krak razporejen pravokotno na pritrdilni del. Nosilni krak je zasnovan tako, da vsaj ena njegova podporna točka, ki v vertikalni smeri podpira ohišje ventilatorja in s tem ventilatorski sklop, leži v ravnini, ki poteka vzporedno z ravnino stene gospodinjskega aparata, na kateri je pritrjen nosilec ventilatorskega sklopa oziroma njegov pritrdilni del, in je od ravnine stene omenjenega aparata oddaljena najmanj toliko, kot je oddaljenost ravnine, ki je vzporedna z ravnino stene omenjenega aparata in v kateri leži težišče ventilatorskega sklopa.Preferably, the support arm is arranged perpendicular to the fastening part. The supporting arm is designed in such a way that at least one of its support points, which vertically supports the fan housing and thus the fan assembly, lies in a plane that runs parallel to the plane of the wall of the household appliance, on which the fan assembly support or its fastening part is attached , and is at least as far from the plane of the wall of the mentioned device as the distance of the plane that is parallel to the plane of the wall of the mentioned device and in which the center of gravity of the fan assembly lies.
Vsakokratni nosilni krak je materialnosklepno povezan s pritrdilnim delom nosilca ventilatorskega sklopa. Pritrdilni del nosilca ventilatorskega sklopa ima v zgornjem delu na strani, ki v montiranem stanju gleda proti steni ohišja, nastavek s skoznjo vijačno luknjo. Pritrdilni del tvorjen kot ravninski element, lahko je v obliki ravne plošče.Each support arm is materially connected to the fastening part of the fan assembly support. The fastening part of the fan assembly support has a fitting with a through screw hole in the upper part on the side facing the wall of the housing in the assembled state. The fastening part is formed as a planar element, it can be in the form of a flat plate.
Da se doseže čim večje dušenje prenosa vibracij iz ohišja ventilatorja na nosilec ventilatorskega sklopa in naprej na ohišje aparata, je lahko na vsakokratnem nosilnem kraku nameščen elastični element iz vibroizolacijskega materiala za dušenje vibracij. Nosilec ventilatorskega sklopa je izdelan iz materiala iz umetne snovi ali iz kovinskega materiala.In order to achieve the greatest possible damping of the transmission of vibrations from the fan housing to the support of the fan assembly and further to the appliance housing, an elastic element made of vibration isolation material can be installed on each support arm to dampen vibrations. The support of the fan assembly is made of plastic material or metal material.
Ohišje ventilatorja je ločljivo pritrjeno na nosilec ventilatorskega sklopa s pomočjo oblikosklepne elastične povezave.The fan housing is detachably attached to the support of the fan assembly by means of a form-fitting elastic connection.
Hladilni in/ali zamrzovalni aparat , prednostno gospodinjski hladilni in/ali zamrzovalni aparat, po izumu zmanjšuje prenos vibracij z ventilatorskega sklopa in s tem znižuje hrup celotnega aparata. Prenos vibracij na ohišje omenjenega aparata je zmanjšan zaradi vgradnje nosilca ventilatorskega sklopa, ki izkazuje vibroizolacijske lastnosti.According to the invention, a cooling and/or freezing appliance, preferably a household cooling and/or freezing appliance, reduces the transmission of vibrations from the fan assembly and thereby reduces the noise of the entire appliance. The transmission of vibrations to the housing of the mentioned device is reduced due to the installation of the fan assembly support, which exhibits vibration isolation properties.
Nosilec ventilatorskega sklopa po izumu sam po sebi deluje kot elastični element kakor tudi s svojo pritrditvijo na ohišje omenjenega aparata in s pritrditvijo ventilatorskega sklopa nanj, s čimer se duši vibracije, da bi se prenašale z ventilatorskega sklopa preko področja vpetja na ohišje aparata.According to the invention, the support of the fan assembly acts in itself as an elastic element, as well as by its attachment to the housing of the mentioned apparatus and by the attachment of the fan assembly to it, thereby damping the vibrations to be transmitted from the fan assembly via the area of attachment to the housing of the apparatus.
Lastnosti nosilca kot elastičnega elementa so dosežene z obliko kot tudi z izbiro materiala omenjenega nosilca. K dušenju vibracij in zmanjšanju prenosa vibracij lahko prispevajo tudi elastični elementi na stičnih mestih med ventilatorskim sklopom in nosilcem ventilatorskega sklopa oziroma na stičnih točkah nosilca ventilacijskega sklopa z ohišjem gospodinjskega aparata. To je možno doseči s pomočjo znanih konstrukcijskih prijemov, kot so npr. vitki, lahko upogljivi deli nosilca ventilatorskega sklopa, preko katerih se prenašajo sile z ventilatorskega sklopa, nosilec ventilatorskega sklopa izveden iz več elementov, pri čemer so določeni deli izdelani iz mehkejšega in s tem bolj elastičnega in/ali vibroizolacijskega materiala, npr. po metodi tako imenovanega dvojnega brizganja itd.The properties of the support as an elastic element are achieved by the shape as well as by the choice of material of said support. Elastic elements at the points of contact between the fan assembly and the support of the fan assembly, or at the points of contact of the support of the ventilation assembly with the housing of the household appliance, can also contribute to the damping of vibrations and the reduction of vibration transmission. This can be achieved with the help of well-known construction methods, such as e.g. slender, easily bendable parts of the fan assembly support, through which the forces from the fan assembly are transmitted, the fan assembly support is made of several elements, whereby certain parts are made of a softer and therefore more elastic and/or vibration-isolating material, e.g. by the so-called double injection method, etc.
Zaradi podprtja ventilatorskega sklopa v področju njegovega težišča je dosežena minimalna statična obremenitev elastičnih elementov, kar ima pozitiven učinek na togost oziroma elastičnost elastičnih elementov. Togost teh elementov ostane skoraj nespremenjena. Visoke obremenitve elastičnih elementov bi namreč povečale togost teh elastičnih elementov in posledično bi bila zmožnost dušenja dinamičnih obremenitev znatno zmanjšana. V primeru vpetja ventilatorskega sklopa z nosilcem ventilatorskega sklopa se zniža prenosnost vibracij od področja vpetja ventilatorskega sklopa do ohišja aparata.Due to the support of the fan assembly in the area of its center of gravity, the minimum static load of the elastic elements is achieved, which has a positive effect on the stiffness or elasticity of the elastic elements. The stiffness of these elements remains almost unchanged. High loads on elastic elements would increase the stiffness of these elastic elements and, as a result, the ability to absorb dynamic loads would be significantly reduced. In the case of fastening the fan assembly with the fan assembly support, the transmission of vibrations from the area of fastening of the fan assembly to the device housing is reduced.
Nosilec ventilatorskega sklopa je togo pritrjen na ohišje gospodinjskega aparata z ločljivo ali neločljivo zvezo, kot je vijačna zveza ali katerakoli druga znana vrsta oblikosklepne zveze. Namestitev in pritrditev ventilatorskega sklopa na nosilec ventilatorskega sklopa je izvedena z ločljivo ali neločljivo zvezo, prednostno z oblikosklepno zvezo take vrste, ki omogoča njegovo namestitev in pritrditev brez uporabe dodatnega orodja, medtem ko se za njegovo odstranitev zahteva dodatno orodje. Takšna pritrditev je lahko izvedena npr. s splošno znano zaskočno povezavo. Na ta način je zagotovljena tudi varnost, da uporabnik gospodinjskega aparata ne more odstraniti in s tem posegati v področje njegovega delovanja.The support of the fan assembly is rigidly attached to the housing of the household appliance by a separable or integral connection, such as a screw connection or any other known type of form-fitting connection. The installation and fastening of the fan assembly to the fan assembly support is carried out with a separable or non-separable connection, preferably with a form-fitting connection of a type that allows its installation and fastening without the use of additional tools, while its removal requires an additional tool. Such attachment can be carried out e.g. with the commonly known snap connection. In this way, safety is also ensured, so that the user cannot remove the household appliance and thereby interfere with its area of operation.
Nosilec ventilatorskega sklopa je zaradi njegove enostavne oblike moč izdelovati iz različnih materialov, tako kovinskih kot tudi iz materialov iz umetne snovi. Še posebej je ekonomsko in oblikovno ugodna izdelava nosilca iz umetne snovi.Due to its simple shape, the support of the fan assembly can be made of various materials, both metal and plastic. It is especially economical and design-friendly to make the support out of synthetic material.

Ventilator 6 je vpet v ohišju 7 ventilatorja, pri čemer je vpetje izvedeno z elastičnimi elementi iz vibroizolacijskega materiala, ki dušijo vibracije in s tem zmanjšuje prenos vibracij z ventilatorja na ohišje ventilatorja.The refrigerating and/or freezing appliance 100 comprises a housing 1 with an opening 2, which enables food to be placed in said appliance and cooled food to be taken from it; the door 3, which closes the opening 2 and, together with the housing 1, surrounds at least one cell 4 with at least one space for storing foodstuffs below or above the freezing temperature; in the cell 4, at least one fan assembly 5 is arranged, which comprises a fan 6 with a fan and a housing 7 of the fan. The fan 6 is clamped in the fan housing 7, whereby the clamping is made with elastic elements made of vibration-insulating material, which dampen vibrations and thus reduce the transmission of vibrations from the fan to the fan housing.
Ventilatorski sklop 5 je na ohišje 1 aparata pritrjen s pomočjo nosilca 8 ventilatorskega sklopa. Nosilec 8 ventilatorskega sklopa obsega pritrdilni del 10 in vsaj en nosilni krak 9, ki je razporejen pravokotno na pritrdilni del 10 in z njim materialnosklepno povezan tako, da v montiranem stanju sega v notranjost celice 4 in skupaj s pritrdilnim delom 10 oblikuje prostor 18 za sprejem ventilatorskega sklopa 5. Vsaj en nosilni krak 9 je zasnovan tako, da podpira ohišje 7 ventilatorja in s tem ventilatorski sklop 5 v vertikalni smeri v vsaj eni podporni točki, ki leži v ravnini Z, ki poteka vzporedno z ravnino S stene omenjenega aparata, na kateri je pritrjen nosilec 8 ventilatorskega sklopa oziroma njegov pritrdilni del 10, in je od ravnine S stene omenjenega aparata oddaljena najmanj toliko, kot je oddaljenost ravnine T, v kateri leži težišče ventilatorskega sklopa 5 in je vzporedna z ravnino S stene omenjenega aparata.The fan assembly 5 is attached to the housing 1 of the device by means of the support 8 of the fan assembly. The support 8 of the fan assembly comprises a mounting part 10 and at least one supporting arm 9, which is arranged perpendicular to the mounting part 10 and is materially connected to it in such a way that in the assembled state it extends into the interior of the cell 4 and together with the mounting part 10 forms a space 18 for receiving of the fan assembly 5. At least one supporting arm 9 is designed to support the fan housing 7 and thus the fan assembly 5 in a vertical direction in at least one support point lying in the plane Z, which runs parallel to the plane S of the wall of said apparatus, on to which the support 8 of the fan assembly or its fastening part 10 is attached, and is at least as far from the plane S of the wall of the mentioned apparatus as the distance of the plane T, in which the center of gravity of the fan assembly 5 lies and is parallel to the plane S of the wall of the said apparatus.
Pritrdilni del 10 je v izvedbenem primeru tvorjen kot ravninski element v obliki ravne plošče, kar pa ne izključuje drugih oblik, kot je, okvir, neravna plošča in drugo. Pritrdilni del 10 ima v zgornjem delu 12 na strani, ki v montiranem stanju gleda proti steni 14 ohišja aparata, nastavek 15 s skoznjo vijačno luknjo 16 za pritrditev nosilca 8 ventilatorskega sklopa na ohišje 1 aparata s pomočjo vijaka.. Pritrdilni del 10 in vsakokratni nosilni krak 9 sta materialnosklepno povezana.

Ventilatorski sklop 5 je vstavljen v prostor 18, ki ga oblikujejo pritrdilni element 10 in vsakokratni nosilni krak 9. Ohišje 7 ventilatorja je oblikovano tako, da vsaj z enim delom ujema z vsakokratnim nosilnim krakom 9 in nanj nalega. Vsakokratni nosilni krak 9 je razporejen na nosilnem delu 10 tako, da ujema s soležnim pritrdilnim delom ohišja 7 ventilatorja.The fan assembly 5 is inserted into the space 18 formed by the fastening element 10 and the individual support arm 9. The fan housing 7 is designed so that at least one part matches the individual support arm 9 and rests on it. Each support arm 9 is arranged on the support part 10 in such a way that it matches the adjacent fastening part of the fan housing 7.
Ohišje 7 ventilatorja je lahko oblikovano tudi tako, da nalega na nosilni krak 9 po celotni dolžini nosilnega kraka 9, ali zgolj na delu njegove dolžine. Ne glede na dolžino naleganja, ohišje 7 ventilatorja, gledano pravokotno na pritrdilni del 10, vedno nalega na nosilni krak 9 v točki, ki je od pritrdilnega dela 10 vsaj enako oddaljena kot je od pritrdilnega dela 10 oddaljeno težišče T ventilatorskega sklopa 5.The housing 7 of the fan can also be designed so that it rests on the support arm 9 along the entire length of the support arm 9, or only on part of its length. Regardless of the mounting length, the housing 7 of the fan, viewed perpendicularly to the mounting part 10, always rests on the support arm 9 at a point that is at least the same distance from the mounting part 10 as the center of gravity T of the fan assembly 5 is from the mounting part 10.
Ohišje 7 ventilatorja je na nosilec 8 ventilatorskega sklopa ločljivo pritrjeno s pomočjo oblikosklepne elastične povezave, ki za namestitev in pritrditev ventilatorskega sklopa 5 ne zahteva dodatnega orodja. Za odstranitev ventilatorskega sklopa 5 je potrebno orodje. S tem je izpolnjena zahteva glede varnosti uporabnika.The housing 7 of the fan is separately attached to the support 8 of the fan assembly by means of a form-fitting elastic connection, which does not require additional tools for installation and fastening of the fan assembly 5. A tool is required to remove the fan assembly 5. This fulfills the requirement regarding user safety.
Ventilatorski sklop 5 je razporejen v celici 4 aparata, prednostno v enem izmed kotov, tako daje vpliv na zmanjšanje uporabnega prostora čim manjši.The fan assembly 5 is arranged in the cell 4 of the device, preferably in one of the corners, so that the impact on the reduction of usable space is as small as possible.
Nosilec 8 ventilatorskega sklopa je preko nastavka 15, kije razporejen na zadnji strani pritrdilnega dela 10, togo pritrjen na eno od notranjih sten 14 ohišja aparata, prednostno na zadnjo notranjo steno ohišja aparata. Pritrditev nosilca 8 ventilatorskega sklopa je izvedena z vijačno zvezo v zgornjem delu 12 osnovne plošče tako, da vsakokratni nosilni krak 9 sega v notranjost celice 4. Spodnji del 13 pritrdilnega dela je v montiranem stanju odmaknjen od notranje stene 14 ohišja aparata. Na spodnjem delu 13 pritrdilnega delaje razporejen vsaj en, prednostno več, elastičnih elementov 17 iz vibroizolacijskega materiala, ki dušijo prenos vibracij z ohišja 7 ventilatorja na ohišje 1 aparata.The support 8 of the fan assembly is rigidly attached to one of the inner walls 14 of the device housing, preferably to the rear inner wall of the device housing, via the attachment 15, which is arranged on the rear side of the fastening part 10. The support 8 of the fan assembly is fastened with a screw connection in the upper part 12 of the base plate so that each support arm 9 reaches inside the cell 4. The lower part 13 of the fastening part is moved away from the inner wall 14 of the device housing in the assembled state. At least one, preferably several, elastic elements 17 made of vibration-insulating material are arranged on the lower part 13 of the fastening device, which dampen the transmission of vibrations from the fan housing 7 to the device housing 1.
Za doseganje čim manjšega prenosa vibracij iz ohišja 7 ventilatorja na ohišje 1 aparata je nameščen dodatni elastični element 20 iz vibroizolacijskega materiala na vsakokratnem nosilnem kraku 9 na mestu, kjer ohišje 7 ventilatorja nalega na nosilni krak 9.In order to minimize the transmission of vibrations from the housing 7 of the fan to the housing 1 of the device, an additional elastic element 20 made of vibration isolation material is installed on each support arm 9 at the place where the fan housing 7 rests on the support arm 9.
Da se prepreči stik ventilatorskega sklopa 5 z ohišjem 1 aparata, so na ohišju 7 ventilatorja dodatno nameščeni elastični elementi 21 iz vibroizolacijskega materiala, ki dodatno dušijo prenos vibracij z ohišja 7 ventilatorja na ohišje 1 aparata.In order to prevent contact of the fan assembly 5 with the housing 1 of the device, elastic elements 21 made of vibration isolation material are additionally installed on the housing 7 of the fan, which additionally suppress the transmission of vibrations from the housing 7 of the fan to the housing 1 of the device.
