Description

Modularno zasnovana hladilna enotaModularly designed cooling unit

Predmetni izum se nanaša na modularno zasnovano hladilno enoto, prednostno na hladilno enoto pri t.i. no-frost zamrzovalnih aparatih, obsegajočo uparjalnik z grelnikom, uparjalnik obdajajočo izolacijo, ploščo odtoka kondenzata, nastavek za odtok kondenzata z grelnikom in ventilator, pri čemer se omenjeni sklop sestavi na ločenem mestu in kasneje vgradi v zamrzovalni aparat.The present invention relates to a modularly designed refrigeration unit, preferably to a refrigeration unit at e.g. no-frost freezers, comprising a evaporator with a heater, an evaporator surrounding insulation, a condensate drain plate, a condensate drain plug with a heater and a fan, said assembly assembled separately and subsequently incorporated into the freezer.

Uvodoma navedene hladilne enote so znane in se jih uporablja, a imajo kar nekaj znatnih pomanjkljivosti. Predvsem je za vse znane hladilne enote značilno, da je uparjalnik hladilne enote povezan s povratno cevjo na svoji zadnji, t.j. k hrbtu zamrzovalnega aparata obrnjeni strani. Zaradi tega mora biti v steni aparata zasnovana luknja, skozi katero je speljana omenjena povratna cev, kar pospeši propadanje izolacije. Prav tako je zaradi nedostopnosti povratne cevi otežena tako vgraditev kot tudi vzdrževanje in/ali servisiranje modularno zasnovane hladilne enote.The cooling units mentioned above are known and are being used, but they have some significant drawbacks. In particular, all known cooling units are characterized by the fact that the cooling unit evaporator is connected to a return pipe at its rear, i.e. facing the back of the freezer. For this reason, a hole must be designed in the wall of the apparatus through which the said return pipe is driven, which accelerates the decay of the insulation. The inaccessibility of the return pipe also makes it difficult to install and maintain and / or service a modularly designed cooling unit.

Naloga izuma je ustvariti modularno hladilno enoto, pri kateri bodo odpravljene pomanjkljivosti znanih rešitev.It is an object of the invention to create a modular cooling unit which will eliminate the disadvantages of the known solutions.

Hladilno enoto po izumu je prednostno namenjena uporabi pri t.i. no-frost zamrzovalnem aparatu. To je takšne vrste zamrzovalni aparat, pri katerem se led ne nabira na hladilni enoti, temveč se samodejno odtaljuje, vodo pa odvaja po ustreznem odvodu.The cooling unit of the invention is preferably intended for use in e.g. no-frost freezer. This is a type of freezer where the ice is not accumulated on the cooling unit but is thawed automatically and the water is drained off by a suitable drain.

Uvodoma zastavljeni problem je po izumu rešen s tem, da je tako dovodna cev hladilne tekočine kot tudi povratna cev hladilne tekočine priključljiva na hladilno enoto na k vratom zamrzovalnega aparata obrnjeni strani. S tem se močno oljaša dostop do priključnih mest in to tako pri montaži hladilne enote ali ob morebitnem popravilu oz. zamenjavi. Pri tem sta omenjeni cevi za hladilno tekočino od kompresorja do priključnih mest na hladilni enoti speljani v izolaciji hrbta in izolaciji stropa ter se k hladilni enoti spustita iz stropa neposredno pred omenjenima priključnima mestoma.The problem of the invention according to the invention is solved by the fact that both the coolant inlet pipe and the coolant return pipe are connected to the cooling unit on the side of the freezer. This greatly facilitates access to the connection points, both when installing the cooling unit or in the event of repair or repair. replace. In doing so, said coolant pipes from the compressor to the connection points on the cooling unit are routed in the back and ceiling insulation and are lowered from the ceiling directly in front of the said connection points.

Nadalje je po izumu predvideno, da je na strani hladilne enote, obrnjeni k hrbtu in proč od stropa, skozi odprtino v hladilni enoti vstavljiv ventilator. S tem se doseže hitro in enostavno menjavo ventilatorja.It is further provided according to the invention that a fan is inserted on the side of the cooling unit, facing the back and away from the ceiling, through an opening in the cooling unit. This makes it quick and easy to replace the fan.

K hrbtu obrnjen nastavek hladilne enote za odvod kondenzata je pri tem speljan v odtok, ki pa je predmet druge patentne prijave. Omenjeni odtok kondenzata je pri tem speljan v izolaciji hrbta zamrzovalnega aparata.The nozzle of the condensate drainage unit facing the back is driven into the drain, which is the subject of another patent application. Said condensate drain is in the insulation of the back of the freezer.

Izum je v nadaljevanju podrobneje predstavljen na osnovi izvedbenega primera in s pomočjo priložene skice, kjer je v navpičnem prerezu shematsko predstavljen t.i. no-frost zamrzovalni aparat.The invention will now be described in more detail on the basis of an embodiment and with the aid of the accompanying drawing, in which a so-called so-called schematic representation is shown in vertical section. no-frost freezer.

Zamrzovalni aparat obsega z vrati 1 zaprto ohišje 2, v katerem je po višini razporejen niz predalov 3 za shranjevanje hrane. V območju dna 4 ohišja 2 je razporejen kompresor 5, ki skrbi za vzdrževanje izbrane temperature v notranjosti zamrzovalnega aparata. V območju neposredno pod stropom 6 ohišja 2 je razporejena hladilna enota 7, ki je po eni strani povezana z dovodno cevjo 8 in povratno cevjo 9 hladilne tekočine, po drugi strani pa je nastavek 10 za odtok staljenega ledu povezan z odvodom 11 vode in/ali kondenzata. Hladilna enota 7 je nadalje opremljena z ventilatorjem 12.The freezer comprises a closed housing 2 with a door 1 in which a set of drawers 3 for storing food is arranged in height. A compressor 5 is arranged in the bottom area 4 of the housing 2, which maintains the selected temperature inside the freezer. In the area directly below the ceiling 6 of the housing 2 is arranged a cooling unit 7 which is connected, on the one hand, to the inlet pipe 8 and the coolant return pipe 9, and on the other, the melt ice outlet 10 is connected to the outlet 11 of water and / or condensate. The cooling unit 7 is further provided with a fan 12.

Po izumu je predvideno, da se tako dovodna cev 8 kot tudi povratna cev 9 hladilne tekočine priključita na hladilno enoto 7 na njeni sprednji strani, t.j. k vratom 1 zamrzovalnega aparata obrnjeni strani. Cevi 8, 9 sta od kompresorja 5 dalje napeljani v izolaciji zamrzovalnega aparata, tako da najprej potekata navpično v hrbtu 13 zamrzovalnega aparata, nakar sta dalje vodoravno speljani v izolaciji v stropu 6, iz katerega se v območju sprednjega dela hladilne enote 7, t.j. dela, ki je obrnjen k vratom 1 zamrzovalnega aparata, spustita navpično navzdol. S tem se močno olajša povezava dovodne cevi 8 in povratne cevi 9 hladilne tekočine s hladilno enoto 7, in to tako pri sami montaži hladilne enote 7 v zamrzovalni aparat kot tudi ob morebitnem popravilu ali zamenjavi hladilne enote. Povezava cevi 8, 9 s hladilno enoto 7 je po sebi znana in zato ni podrobneje opisana.According to the invention it is contemplated that both the inlet pipe 8 and the return pipe 9 of the coolant be connected to the cooling unit 7 on its front, i.e. to the door of the freezer door facing the side. The tubes 8, 9 are further routed from the compressor 5 in the insulation of the freezer so that they first extend vertically in the back 13 of the freezer, and then are horizontally routed in the insulation in the ceiling 6 from which, in the region of the front of the refrigeration unit 7, i.e. lower the portions facing the freezer door 1 vertically downwards. This greatly facilitates the connection of the inlet pipe 8 and the return pipe 9 of the coolant to the cooling unit 7, both when installing the cooling unit 7 in the freezer and when repairing or replacing the cooling unit. The connection of pipes 8, 9 to the cooling unit 7 is known per se and is therefore not described in detail.

V območju zadnjega dela hladilne enote 7, t.j. dela, ki je obrnjen k hrbtu 13 zamrzovalnega aparata, je razporejen ventilator 12, ki je v hladilno enoto 7 smotrno vstavljiv s proč od stropa 6 obrnjene strani skozi odprtino 14. Pri tem je po izumu predvideno, da je ventilator 12 vstavljiv v hladilno enoto 7 na način, da ostane hladilna enota 7, npr. ob zamenjavi ventilatorja 12, nepremično na svojem mestu in je ni potrebno na nikakršen način niti premikati niti odstraniti iz zamrzovalnega aparata.In the region of the rear of the refrigeration unit 7, i.e. of the part, which faces the back 13 of the freezer, there is arranged a fan 12, which is conveniently inserted into the cooling unit 7, away from the ceiling 6, facing through the opening 14. According to the invention, it is provided that the fan 12 is inserted into the cooling unit 7 in such a way that the cooling unit 7 remains, e.g. when replacing fan 12, it is stationary and must not be moved or removed in any way from the freezer.

Hladilna enota 7, v omenjenem zadnjem delu, obsega nastavek 10 za odvod vode in/ali kondenzata, ki je speljan v odvod 11, ki poteka v izolaciji hrbta 13 zamrzovalnega aparata. Omenjeni odvod 11 je predmet ločene patentne prijave in zato na tem mestu ni podrobneje opisan.The cooling unit 7, in said rear section, comprises a nozzle 10 for draining water and / or condensate, which is fed into the drain 11, which runs in the insulation of the back 13 of the freezer. Said branch 11 is the subject of a separate patent application and is therefore not described in detail here.
