Abstract

Riešenie sa týká zabezpečenia cyklického odmrazovania výparnikov chladničiek a mrazničiek proti vzniku Iadových zostatkov na prechodkách, t. j. na prívodných a odvádzacích potrubiaoh, stěnou spotrebiča a výparníkom. Tvorbě Iadových zostatkov sa zabráni tým, že tykavka termostatu s konštantnou zapínacou teplotou nad 0 °C je připevněná k telesu výparníka, pričom zároveň prechádza prechodkou, alebo sa jej len z vonkajška dotýká. V mieste dotyku s prechodkou je na tykavke termostatu vytvořené zobáčkovité vyhnutie, pre umožnenie úplného odkvapkania roztopenej námrazy.The solution concerns the provision of cyclic defrosting of the evaporators of refrigerators and freezers against the formation of Iodine residues on transitions, i.e. on the inlet and outlet pipes, the wall of the appliance and the evaporator. The formation of iodine residues is prevented by the fact that the thermocouple with a constant switch-on temperature above 0 °C is attached to the body of the evaporator, while at the same time passing through the passage, or only touching it from the outside. At the point of contact with the transition, there is a beak-like avoidance created on the thermostat's flask, to allow the melted ice to drip completely.

Description

Vynález sa týká zariadenia pre zabezpečenie cyklického odmrazovania výparníkov chladničiek a mrazničiek proti tvorbě ladových zostatkov na prechodkách, to je na prívodných a odvádzaclch potrubiach, medzi výparníkom a stěnou chladničky alebo mrazničky.BACKGROUND OF THE INVENTION The present invention relates to a device for providing cyclic defrosting of refrigerators and freezer evaporators against the formation of ice residues at the transition, i.e., inlet and outlet pipes, between the evaporator and the wall of the refrigerator or freezer.

V chladničkách s cyklicky odmrazovaným výparníkom, najma v chladničkách, ktoré obsahujú komoru vybavenú automaticky odmrazovaným výparníkom pomocou ohřevu elektrickým vyhrievacim telesom, zostávajú niekedy na prechodkách ladové zostatky, ktoré obyčajne nařastajů tak, že sa poruší funkcia odmrazovania. Takýto stav je uživatelom považovaný za poruchu, ktorú žiada odstránit. Výrobca takúto chybu nemohol opravit a z tohto dfivodu bol nútený vymieňať výrobok za nový.In refrigerators with a cyclically defrosted evaporator, especially refrigerators that contain a chamber equipped with an automatically defrosted evaporator by heating with an electric heater, there are sometimes left-over ice residues on the transitions, which usually grow so that the defrost function is impaired. Such a condition is considered by the user to be a malfunction that he / she wishes to remedy. The manufacturer could not correct such a mistake and for this reason he was forced to replace the product with a new one.

Kombinované jednokompresorové chladničky mávajú v chladiacom priestore automaticky odmrazovaný výparník pomocou elektrického vyhrievacieho telesa po každom cykle činnosti chladiacej jednotky. Teplota v chladiacom aj mraziacom priestore je obyčajne regulovaná termostatom s konštantnou zapínacou teplotou pohybujúcou sa nad 0 °C. Tykavká termostatu bývá umiestnená na odmrazovacom výparniku. Pri hraničných podmienkach činnosti výrobku, jeho nadmernom zatažení, následkom starnutia použitých materiálov, neodborného zásahu obsluhy alebo nedokonalého servisu, začínají! sa vytvárať ladové zostatky na prechodkách a Iadový dendrit sa postupné rozrastie aj na časti samotného výparníka. Tento stav považuje uživatel za poruchu, ako bolo už uvedené.Combined single-compressor refrigerators have an automatically defrosted evaporator in the refrigerator compartment by means of an electric heater after each cycle of the chiller operation. The temperature in both the freezing and freezing compartments is usually regulated by a thermostat with a constant switching temperature above 0 ° C. The thermostatic volatile is located on the de-icing evaporator. Under extreme conditions of product operation, overloading, aging of used materials, improper operator intervention or imperfect service, they begin! The ice dendrite will gradually expand to parts of the evaporator itself. This condition is considered as a malfunction by the user as already mentioned.

Popísanej poruche zabráni zariadenie pre zabezpečenie cyklického odmrazovacieho výparníkov chladničiek a mrazničiek podlá vynálezu, ktorého podstatou je, že tykavka termostatu je připevněná k telesu výparníka, pričom zároveň prechádza prechodkou, alebo sa jej len dotýká z vonkajšej časti. V mieste dotyku s prechodkou je na tykavke vytvořené zobáčkovité vyhnutie pre umožnenie úplného odkvapkania roztopenej námrazy.The described failure is prevented by the device for providing cyclic defrosters of refrigerators and freezers according to the invention, which is based on the fact that the thermostat rod is attached to the evaporator body while passing through the grommet or just touching it from the outside. At the point of contact with the bushing, a beak-like curvature is formed on the bulb to allow complete melting of the melted icing.

Výhodou zariadenia podlá vynálezu je, že zabezpeč! dokonalú funkciu odmrazovania aj v případe abnormálneho zaťaženia výrobku, čím sa zabráni vzniknút poruche, ktorá bola považovaná za neodstránitelnú.An advantage of the device according to the invention is that perfect defrosting function even in case of abnormal load on the product, thus avoiding the occurrence of a malfunction that was considered unrecoverable.

Na pripojenom výkrese je v schéme naznačený příklad použitia zariadenia podlá tohoto vynálezu.The accompanying drawing shows an example of the use of the device according to the invention.

V stene J5 skrlne chladničky je umiestnená prechodka £ v ktorej je uložené privodné a odvádzacie potrubie výparníka 2 cyklicky odmrazovaného ohrevom. Zariadenie je tvořené tykavkou 3 termostatu 2 s konštantnou zapínacou teplotou nad 0 °C, ktorá je upevněná na výparniku J sponou 2, pričom zároveň sa dotýká vonkajšej časti prechodky 4. V mieste dotyku prechodky _4 a tykavky 2 íe na tykavke 2 vytvořené zobáčkovité vyhnutie 6, ktoré umožňuje odkvapkávanie roztopenej námrazy. Zariadenie nedovol! zapnúť termostatu 2 chladiacu jednotku chladničky bez dokonalého odmrazenia výparníka 1 aj v kritických miestach tvorenia ladových zbytkov, to je na prechodke 4.In the wall 5 of the refrigerator cabinet there is a bushing 6 in which the inlet and outlet pipes of the evaporator 2 are cyclically defrosted by heating. The device consists of a thermostat tube 2 with a constant switching temperature above 0 ° C, which is fastened to the evaporator J by a clip 2, while at the same time touching the outer part of the tube 4 . 6, which allows the melted icing to drip. Do not allow the device! turn on the thermostat 2 of the refrigerator cooling unit without perfect defrosting of the evaporator 1, even at critical points of ice formation, that is at junction 4.

Použitie zariadenia podlá vynálezu umožňuje pri znížených výrobných nákladoch zvýšit spolahlivost a životnost chladničiek a mrazničiek a v servisněj sieti, pri nepatrných nákladoch, opravit výrobok priamo u uživatela.The use of the device according to the invention makes it possible to increase the reliability and durability of refrigerators and freezers at a reduced production cost and to repair the product directly at the user in a service network at a low cost.
