Description

Izboljšani hladilni sistem zamrzovalnikaImproved freezer cooling system

Predloženi izum se nanaša na izboljšani hladilni sistem zamrzovalnika, prednostno gospodinjskega zamrzovalnika, ki obsega celico, v kateri se nahaja vsaj en predelek za shranjevanje živil pod temperaturo ledišča, pri čemer je omenjeni predelek hlajen s pomočjo vsaj enega cevno žičnega uparjalnika, razporejenega ob vsaj eni steni omenjene celice.The present invention relates to an improved refrigeration system of a freezer, preferably a household freezer, comprising a cell in which at least one food storage compartment is located below freezing temperature, said compartment being cooled by at least one tubular wire evaporator arranged along at least one the wall of said cell.

Hladilni sistem zamrzovalnika uvodoma navedene vrste je znan. Tako obstaja na primer rešitev, pri kateri se ustrezno temperaturo v zamrzovalniku doseže s cevno žičnim uparjalnikom, ki je skupaj s hladilnim sistemom za hladilnik zasnovan kot en sam element in poteka v vodoravni ravnini, med predali za hrambo živil, in ob stenah hladilnika in/ali zamrzovalnika. Pomanjkljivost zadevne rešitve leži v tem, da se na opisan način znatno zmanjša koristen volumen zamrzovalnika.The freezer refrigeration system of the type mentioned above is known. Thus, for example, there is a solution in which a suitable temperature in the freezer is achieved by a tubular wire evaporator, which, together with the refrigerator cooling system, is designed as a single element and runs horizontally, between the food storage compartments, and along the walls of the refrigerator and / or freezer. The disadvantage of this solution is that the useful volume of the freezer is significantly reduced in the manner described.

Naloga predloženega izuma je ustvariti izboljšani hladilni sistem zamrzovalnika, s katerim se bo odpravilo pomanjkljivosti znanih rešitev in sočasno povečalo učinkovitost zamrzovalnika.It is an object of the present invention to provide an improved freezer refrigeration system which will eliminate the disadvantages of known solutions and at the same time increase the efficiency of the freezer.

Zastavljena naloga je po izumu rešena s tem, da je cevno žični uparjalnik, ki je razporejen v notranjosti celice zamrzovalnika, hidravlično povezan s cevnim uparjalnikom, ki na način navitja poteka po zunanjem obodu omenjenega predelka. Seveda pa se razume, ne da bi se pri tem oddaljili os smisla in obsega zaščite, da lahko omenjeni cevni uparjalnik meandrasto poteka v ravnini vsaj ene od sten omenjene celice zamrzovalnika. Omenjeni cevni uparjalnik pri tem v celoti poteka v izolaciji omenjene celice. Po izumu je predvideno, da se omenjeni cevni uparjalnik v zamrzovalnik namesti pred namestitvijo izolacije in pred sestavljanjem zamrzovalnika. Nadalje je po izumu predvideno, da se omenjeni cevno žični uparjalnik namesti v zamrzovalnik, ko je le-ta v celoti sestavljen, pri čemer se vsakokratni prosti konec omenjenega cevno žičnega uparjalnika hidravlično poveže z vsakokratnim, v notranjost hladilnega prostora zamrzovalnika štrlečim, prostim koncem omenjenega cevnega uparjalnika. Pri tem se omenjeni vsakokratni prosti konec omenjenega cevno žičnega uparjalnika hidravlično poveže z omenjenim vsakokratnim prostim koncem omenjenega cevnega uparjalnika s pomočjo hladnega spoja z mehansko deformacijo.The object of the invention is solved by the fact that the tubular wire evaporator disposed inside the freezer cell is hydraulically connected to the tubular evaporator which extends in the winding manner along the outer circumference of said compartment. However, it is understood without departing from the axis of meaning and scope of protection that said tubular evaporator may meander in the plane of at least one of the walls of said freezer cell. Said tube evaporator is completely run in isolation of said cell. According to the invention, it is contemplated that said tubular evaporator be installed in the freezer before installing the insulation and before assembling the freezer. It is further contemplated according to the invention that said tubular wire evaporator is installed in the freezer when fully assembled, with each respective free end of said tubular wire evaporator being hydraulically connected to the projecting, free inside end of the freezer cooling space of said tube evaporator. In doing so, said respective free end of said tubular wire evaporator is hydraulically connected to said respective free end of said tubular evaporator by means of a cold joint with mechanical deformation.

Izum je v nadaljevanju podrobneje opisan s sklicevanjem na priloženo skico, kjer je v tridimenzionalnem pogledu shematsko prikazan hladilni sistem zamrzovalnika po izumu.The invention will now be described in more detail with reference to the accompanying drawing, in which, in three-dimensional view, a cooling system of the freezer of the invention is schematically shown.

Zamrzovalnik po izumu sestoji iz celice 1, v katere notranjosti se nahaja zamrzovalni prostor 2, ki je po višini predeljen na več predelkov, v katerih se nahajajo predali za zamrzovanje in/ali shranjevanje živil. Vsakokratni omenjeni predelek oz. predal je na po sebi znan način ločen s cevno žičnim uparjalnikom 3, 4, 5, katerih vsak je prednostno razporejen v vodoravni ravnini. Omenjena celica 1 zamrzovalnika je obdana z neprikazano izolacijo. Z namenom izboljšanja učinkovitosti zamrzovalnika je omenjena celica 1 na način navitja 6 obdana s cevnim uparjalnikom 7, ki v celoti poteka v izolaciji omenjene celice 1. Seveda pa se razume, ne da bi se pri tem oddaljili os smisla in obsega zaščite, da lahko omenjeni cevni uparjalnik 7 meandrasto poteka v ravnini vsaj ene od sten omenjene celice 1.The freezer according to the invention consists of a cell 1, inside which is a freezer compartment 2, which is height-altered into several compartments in which there are drawers for freezing and / or storing food. The said compartment, respectively. the compartment is, in a manner known per se, separated by a tubular wire evaporator 3, 4, 5, each of which is preferably arranged in a horizontal plane. Said freezer cell 1 is surrounded by non-visible insulation. In order to improve the efficiency of the freezer, said cell 1 in the winding manner 6 is surrounded by a tubular evaporator 7, which is completely insulated in said cell 1. Of course, without departing from the axis of meaning and scope of protection, said the meandrast tube evaporator 7 runs in the plane of at least one of the walls of said cell 1.

Pri tem je prvi konec 8 prvega cevno žičnega uparjalnika, ki je na skici prikazan kot zgornji cevno žični uparjalnik 3, v celico 1 na po sebi znan način speljan od neprikazanega kondenzatorja. Omenjeni prvi cevno žični uparjalnik 3 se zatem nadaljuje v drugi cevno žični uparjalnik, ki je na skici prikazan kot srednji cevno žični uparjalnik 4, in še naprej v tretji cevno žični uparjalnik, ki je na skici prikazan kot spodnji cevno žični uparjalnik 5.In this case, the first end 8 of the first tubular wire evaporator, which is shown in the drawing as the upper tubular wire evaporator 3, is connected to the cell 1 in a known manner by itself from a non-shown capacitor. Said first tubular wire evaporator 3 then proceeds to a second tubular wire evaporator, shown in the sketch as a medium tubular wire evaporator 4, and further to a third tubular wire evaporator, shown in the sketch as a lower tubular wire evaporator 5.

Prosti konec omenjenega spodnjega cevno žičnega uparjalnika 5 je v območju stene povezan s cevnim uparjalnikom 7, ki na mestu 10 predira steno omenjene celice 1 in izstopa iz omenjene celice 1 ter se, kot že omenjeno, na način navitja 6 v izolaciji celice 1 • · ovija okoli omenjene celice 1. Prosti konec 11 omenjenega cevnega uparjalnika 7 na mestu predira steno celice 1 in je na po sebi znan način speljan bodisi v hladilnik ali kompresor zamrzovalnika.The free end of said lower tubular wire evaporator 5 is connected in the wall area with a tubular evaporator 7, which at point 10 penetrates the wall of said cell 1 and exits said cell 1 and, as already mentioned, winds 6 in the insulation of cell 1 · wrapped around said cell 1. The free end 11 of said tubular evaporator 7 penetrates the wall of cell 1 in place and is itself known in a known manner, either into a refrigerator or a freezer compressor.

Po izumu je nadalje predvideno, da je pot hladilnega sredstva tudi obrnjena. To pomeni, da je prvi konec 8 prvega cevno žičnega uparjalnika 3 v celico 1 na po sebi znan način speljan od neprikazanega kompresorja in je prosti konec 11 omenjenega cevnega uparjalnika 7, ki na mestu 9 predira steno celice 1, na po sebi znan način speljan v kondenzator.The invention further provides that the refrigerant path is also reversed. This means that the first end 8 of the first tubular wire evaporator 3 is in a known manner directed to the cell 1 by a non-shown compressor and the free end 11 of said tubular evaporator 7, which penetrates the wall of the cell 1 in a known manner, in a known manner into the capacitor.

Nadalje je po izumu predvideno, da se omenjeni cevni uparjalnik 7 navije okoli omenjene celice 1 pred namestitvijo izolacije in pred sestavljanjem zamrzovalnika. Prav tako je predvideno, da se vsakokratni omenjeni cevno žični uparjalnik 3, 4, 5 namesti v zamrzovalnik, ko je le-ta v celoti sestavljen.According to the invention, it is further provided that said tubular evaporator 7 is wound around said cell 1 prior to installation of the insulation and before assembly of the freezer. It is also envisaged that each said tubular wire evaporator 3, 4, 5 is to be installed in the freezer when fully assembled.

Pri tem je po izumu predvideno, da je povezava med cevno žičnim uparjalnikom 5 in cevnim uparjalnikom 7 zasnovana s pomočjo hladnega spoja z mehansko deformacijo.According to the invention, it is contemplated that the connection between the tubular wire evaporator 5 and the tubular evaporator 7 is designed by means of a cold joint with mechanical deformation.
