Description
Kjøleskap. Refrigerator.
Oppfinnelsen angår et kjoleskap med et kjolefag og et frysefag med hver sin fordamper og en felles kompressor og kondensator, hvor kjolefagsfordamperens kanalsystem strekker seg fra inngangen til et dypere sted med en viss høydeforskjell for ved avstengt kompressor å oppnå avriming av kjolefagsfordamperen ved hjelp av varme fra den omgivende kjolefagsluften. The invention relates to a refrigerator with a dress compartment and a freezer compartment each with a separate evaporator and a common compressor and condenser, where the duct system of the dress compartment evaporator extends from the entrance to a deeper place with a certain height difference in order to achieve defrosting of the dress compartment evaporator with the help of heat from the surrounding air of dressmaking.
Ved kjoleskap av denne art arbeider kjolefagsfordamperen i serie med en frysefagsfordamper, idet kjolefagsfordamperen under kompressorens avstengning i det minste stort sett avrimes ved natur-lig oppvarmning, mens kjolemidlet under kompressorens gang forst ledes gjennom kjolefordamperen og deretter gjennom frysefordamperen. En slik fremgangsmåte, ved hvilken kjolefagsfordamperen ikke avrimes på kunstig måte, har store fordeler sammenliknet med avriming ved kunstig oppvarmning. Ifolge oppfinnelsen kreves der således ingen elektrisk energi for avrimingen, hvorved store driftsomkostninger spares og utformningen av kjoleskapet blir enklere. Disse og andre fordeler med denne såkalte "naturlige avriming" medforer dog den lille vanskelig-het å holde tiden for de enkelte avrimingsperiodene så kort at temperaturen i frysefagsfordamperen," som er koplet i serie med kjolefagsfordamperen, ikke stiger for meget. In refrigerators of this type, the clothes evaporator works in series with a freezer evaporator, as the clothes evaporator during the shutdown of the compressor is at least mostly defrosted by natural heating, while the refrigerant during the operation of the compressor is first led through the clothes evaporator and then through the freezer evaporator. Such a method, in which the garment evaporator is not defrosted artificially, has great advantages compared to defrosting by artificial heating. According to the invention, no electrical energy is required for the defrosting, whereby large operating costs are saved and the design of the wardrobe becomes simpler. These and other advantages of this so-called "natural defrosting" entail, however, the slight difficulty of keeping the time for the individual defrosting periods so short that the temperature in the freezer section evaporator, which is connected in series with the clothes section evaporator, does not rise too much.
Med uttrykket "frysefag" menes den del av et kjoleskap i hvilken man holder en temperatur under frysepunktet, fortrinnsvis på -18°C og lavere, og med uttrykket "kjolefag" menes den del som har en temperatur over frysepunktet, fortrinnsvis på +3°C til +7°C. Med kjoleskap menes vanlige kjoleskap for husholdning og liknende kjoleanordninger. By the term "freezer section" is meant the part of a refrigerator in which a temperature is kept below the freezing point, preferably at -18°C and lower, and by the term "dressing section" is meant the part that has a temperature above the freezing point, preferably at +3° C to +7°C. Wardrobes mean ordinary household wardrobes and similar wardrobe devices.
Oppfinnelsens hovedformål er derfor å påskynde den naturlige avriming i kjolefagsfordamperen, forkorte de for avrimingen nodvendige stillstandstider for kompressoren, og å forbedre temperaturforholdene i kjole- og frysefagene. Oppfinnelsen tilsikter også å oppnå dette på en særdeles enkel og drifts-sikker måte. The main purpose of the invention is therefore to speed up the natural defrosting in the dress compartment evaporator, shorten the standstill times for the compressor required for defrosting, and to improve the temperature conditions in the dress and freezer compartments. The invention also aims to achieve this in a particularly simple and reliable way.
Dette oppnås ifolge oppfinnelsen ved at et med kondensatorens utlop forbundet kapillarrør munner ut i en ovre del av kjolefagsfordamperens kanalsystem, og at det dypeste sted i dette system via en kanal er forbundet med frysefagsfordamperen,idet denne kanal forst strekker seg oppover til en ovenfor frysefagsfordamperen beliggende terskel og derfra til frysefagsfordamperen, og at kanalen er således dimensjonert at det etter påbegynnelsen av en kompressor-stillstand i kjolefagsfordamperen frembragte pneumatiske trykk befordrer det flytende kjblemiddel fra kjolefagsfordamperen til frysefagsfordamperen, hvorved nevnte terskel forhindrer tilbakestromning av kjole-middel til kjolefagsfordamperen. According to the invention, this is achieved by a capillary tube connected to the outlet of the condenser opening into an upper part of the cold room evaporator's channel system, and that the deepest place in this system is connected via a channel to the freezer compartment evaporator, as this channel first extends upwards to a place located above the freezer compartment evaporator threshold and from there to the freezer compartment evaporator, and that the channel is dimensioned in such a way that the pneumatic pressure produced after the start of a compressor standstill in the clothes compartment evaporator conveys the liquid conditioner from the clothes compartment evaporator to the freezer compartment evaporator, whereby said threshold prevents the backflow of clothing agent to the clothes compartment evaporator.
Ved et sådant kjoleskap samler det flytende kjdlemiddel seg ved hver fråkopling av kompressoren i det laveste punkt av fordamperen. Det herved enda en stund gjennom kapillarrøret inn-strommende varme kjblemiddel fordampes ved sin ekspansjon og det herved frembragte damptrykk trykker det i fordamperen stå-ende flytende kjblemiddel hurtig gjennom mellomkanalen til frysefagsfordamperen der det oppbevares inntil kompressoren påny settes igang. Det virker herved stabiliserende på frysefagsfordamperen hvis kjolemidlet under stillstanden langsomt kan fordampes og frembringe kulde. Kjolefagsfordamperen kan med fordel utformes som en i faget anordnet platefordamper. Ettersom kjolefagsfordamperen under hver stillstandsperiode With such a refrigerator, the liquid refrigerant collects at the lowest point of the evaporator every time the compressor is switched off. The hot refrigerant flowing in through the capillary tube for a while is vaporized by its expansion and the vapor pressure thus produced pushes the liquid refrigerant in the evaporator quickly through the intermediate channel to the freezer compartment evaporator where it is stored until the compressor is restarted. This has a stabilizing effect on the freezer evaporator if the cooling agent can slowly evaporate during standstill and produce cold. The clothes compartment evaporator can advantageously be designed as a plate evaporator arranged in the compartment. As the dresser evaporator during each standstill period
blir praktisk talt helt avrimet, er ved begynnelsen av perioden rimsjiktet, hvis det overhodet fins, meget tynt, slik at det gjennom den hurtige tomning av fordamperen hurtig toer opp, is practically completely defrosted, at the beginning of the period the frost layer, if it exists at all, is very thin, so that due to the rapid emptying of the evaporator it rapidly rises,
I det område der kapillarrøret innfores i fordamperen, medvirker også det innforte varme kjblemiddel til oppvarmning av fordamperen. Denne fordamper-oppyarmning er dog begrenset i rommet og virker praktisk talt utelukkende i nærheten av inniopet til fordamperen. På den annen side opptrer det ved utgangen fra fordamperens kanalsystem særskilt lave temperaturer under kompressorens gang. For å unngå denne ulempe og forbedre avrimingen står hensiktsmessig et uttak fra kjolefagsfordamperen i varmevekslende forbindelse med et inntak, i hvilket kapillar-rørets munning er således plassert at temperaturen i uttaket kan hbynes av den hbyere temperatur i inntaket. In the area where the capillary tube is inserted into the evaporator, the inserted hot coolant also contributes to heating the evaporator. However, this evaporator arming is limited in space and practically only works near the inlet of the evaporator. On the other hand, particularly low temperatures occur at the outlet of the evaporator's duct system during the operation of the compressor. In order to avoid this disadvantage and improve the defrosting, an outlet from the dresser evaporator is suitably in heat-exchange connection with an inlet, in which the mouth of the capillary tube is placed in such a way that the temperature in the outlet can be increased by the higher temperature in the inlet.
Kapillarrørets munning er med fordel anbragt i fordamper- The mouth of the capillary tube is advantageously placed in the evaporator
platen for kjolefagsfordamperen i avstand fra platens ytterkant. En utforelsesform for oppfinnelsen beskrives i det fblgende the plate for the dresser evaporator at a distance from the outer edge of the plate. An embodiment of the invention is described in the following
med henvisning til tegningene, på hvilke fig* 1 skjematisk viser et kjoleskap med et frysefag og et kjolefag, fig. 2 et husholdningskjbleskap, hvis dor tenkes borttatt og som inne-holder en kjolemaskin ifolge fig* 1, sett forfra, og fig* 3 viser et forstbrret avsnitt av den i fig. 2 viste fordamper. Kbmpressorkjblemaskinen ifolge fig. 1 har på kjent måte en with reference to the drawings, in which fig* 1 schematically shows a wardrobe with a freezer compartment and a clothes compartment, fig. 2 a household wardrobe, the door of which is thought to be removed and which contains a dress machine according to fig* 1, seen from the front, and fig* 3 shows an enlarged section of the one in fig. 2 showed vaporizer. The Kbmpressor cable machine according to fig. 1 has, in a known manner, one
til det elektriske nett sluttet kompressor 11, en kondensator 12, en vertikalt anordnet tbrke 13 med et kapillarrør 14, som er innfort i inngangen 15 til et ror 16 (fig. 3) i normal-ska|>-platefordamperen 18, en som dypf rysef ordamper tjenende U-fordamper 19 med tilhørende samlebeholder 20 og en suge-ledning 21. Fordamperen 18 har fra innlopet 16 til det dypeste sted 23 stadig synkende rbrslbyfer 17, og derfra et oppadgående rbrstykke 24, som i sin bvre del danner en utgang 26 fra fordamperen 18 og der er sluttet til en mellorakanal 25, hvis bvre, to the electrical network connected compressor 11, a condenser 12, a vertically arranged tube 13 with a capillary tube 14, which is inserted into the entrance 15 of a tube 16 (fig. 3) in the normal-ska|>-plate evaporator 18, one which deepf rysef orvamper serving U-evaporator 19 with associated collection container 20 and a suction line 21. The evaporator 18 has from the inlet 16 to the deepest place 23 a constantly descending pipe tube 17, and from there an upward tube piece 24, which in its left part forms an outlet 26 from the evaporator 18 and there is connected to an improvement channel 25, whose left,
i U-form bbyde ende 28 utgjor en hbydeterskel og inngangen til in U-shape, both ends 28 form a height threshold and the entrance to
dypfrysefordamperen 19. U-boyen eller terskelen 28 ligger hoyere enn det tilsluttede rorsystem frem til samlebeholderen 20. Den vertikalt anordnede normalfordamper 18 har forholdsvis stor flate og strekker seg ifolge fig. 2 stort sett over hele hoyden og bredden av kjolefaget 30 i et kjoleskap 31, som også inne-holder et ovenfor kjolefaget anordnet frysefag 32. Normal-fordamperen 18 er anordnet som for-fordamper, mens frysefordamperen 19 derimot danner en etter-fordamper i kjblemaskinen. De to fordampere er innbyrdes forbundet gjennom mellomkanalen 25, som har liten stromningsmotstand. the deep-freeze evaporator 19. The U-buoy or threshold 28 is higher than the connected rudder system up to the collection container 20. The vertically arranged normal evaporator 18 has a relatively large surface and extends according to fig. 2 largely over the entire height and width of the garment compartment 30 in a cabinet 31, which also contains a freezer compartment 32 arranged above the garment compartment. The normal evaporator 18 is arranged as a pre-evaporator, while the freezer evaporator 19, on the other hand, forms a post-evaporator in the ironing machine . The two evaporators are interconnected through the intermediate channel 25, which has little flow resistance.
Av fig» 2 fremgår det også at frysefordamperen 19 på kjent måte er utformet som U-fordamper og kan fremstilles av f.eks. aluminium ved valsning, hvilket også kan skje med normal-fordamperen 18. Man foretrekker dog i henhold til fig. 3 å anvende en ryggskive 33 av plast i hvilken rorsloyfene 17 og det tilsluttende rorstykket 24 innleires. Ryggskiven 33 kan utfores i to sjikt, idet det mellom disse innlegges tynne aluminiumsbånd 54 i kontakt med rorene 17 og 24 for å utjevne temperaturene i fordamperen. Som det fremgår av figuren er kapillarrøret 14 innfort på det hoyeste sted i fordamperen slik at kjolemidlet strommer inn i sloyfen 17 ovenfra. Denne anord-ning er fordelaktig for den pneumatiske utblåsning av fordamperen når kompressoren har stanset. It is also clear from Fig. 2 that the freezer evaporator 19 is designed in a known manner as a U-evaporator and can be made from e.g. aluminum by rolling, which can also happen with the normal evaporator 18. However, according to fig. 3 to use a back disc 33 made of plastic in which the rudder slots 17 and the connecting rudder piece 24 are embedded. The back disc 33 can be lined in two layers, with thin aluminum bands 54 inserted between these in contact with the rudders 17 and 24 to equalize the temperatures in the evaporator. As can be seen from the figure, the capillary tube 14 is inserted at the highest point in the evaporator so that the cooling agent flows into the sloyfen 17 from above. This device is advantageous for the pneumatic blowing out of the evaporator when the compressor has stopped.
Den periodiske inn- og utkopling av kompressoren 11 skjer ved hjelp av en termostat 36, hvis temperaturfoler 37 er plassert i fordamperen 18 i den i fig, 1 viste stilling. Foleren likesom termostatens ovrige deler er utformet på kjent måte og på-virker en stillanordning 39 med en strbmbryter 40,' som i avheng-ighet av foleren 37 bryter og slutter stromraen til kompressoren 11. Denne innkoples for en temperatur over 0°C, f.eks. +5°C, The periodic switching on and off of the compressor 11 takes place by means of a thermostat 36, whose temperature sensor 37 is placed in the evaporator 18 in the position shown in Fig. 1. The sensor, like the other parts of the thermostat, is designed in a known manner and affects a setting device 39 with a power switch 40, which, depending on the sensor 37, breaks and closes the current to the compressor 11. This is switched on for a temperature above 0°C, f .ex. +5°C,
og utkoples ved en bestemt lavere temperatur, f.eks. -10°C. Gjennom den over 0°C liggende innkoplingstemperatur oppnås and is switched off at a certain lower temperature, e.g. -10°C. Through the switch-on temperature above 0°C is achieved
at fordamperen i det minste stort sett er avrimet.når kompressoren igjen innkoples. Avrimingen skjer uten kunstig oppvarmning bare gjennom den under kompressorens stillstand inntred-ende naturlige oppvarmning gjennom den omgivende luft i normal - kjolefaget, hvis temperatur ligger over 0°C, vanligvis mellom that the evaporator is at least largely defrosted. when the compressor is switched on again. The defrosting takes place without artificial heating, only through the natural heating occurring during the compressor's standstill through the surrounding air in the normal garment, whose temperature is above 0°C, usually between
<+>3°C og +7°C. Ved den i fig. 2 og 3 viste kjolefordamper 18 er de to rbr 45 og 26, som danner til- og avlop til fordamperen, anordnet i liten avstand fra hverandre, slik at den av det gjennom kapillarrøret 14 strbmmende varme kjblemedium forårsak-ede temperaturstigning i rorstykket 45 for en del overfores til det av kanalen 26 oppvarmede område 44 og hbyner dettes temperatur. Det er derfor fordelaktig å fore kapillarrørets munning 42 så langt inn fra ryggskivens kant 47 som vist i fig. 3. <+>3°C and +7°C. By the one in fig. 2 and 3, the two tubes 45 and 26, which form the inlet and outlet to the evaporator, are arranged at a small distance from each other, so that the temperature rise in the tube piece 45 caused by the hot cooling medium flowing through the capillary tube 14 for a part is transferred to the area 44 heated by the channel 26 and increases its temperature. It is therefore advantageous to line the mouth of the capillary tube 42 as far in from the edge 47 of the back disc as shown in fig. 3.
Kj61eskapet fungerer som folger: The kitchen works as follows:
Etter at kompressoren er innkoplet av termostaten, suger den via sugeroret 21 kjblemiddel fra frysefordamperen 19 og trykker det til kondensatoren 12, der det varmes og kondenser-es og flyter gjennom tbrken 13 videre gjennom kapillarrøret 14 ovenfra inn i kjblefordamperen 18 på dennes hbyeste sted. I slbyfene 17 og 24 begynner kjblemidlet å koke og delvis fordampes, hvorved det trekker til seg varme fra kjblerommet, som derved avkjbles. Via mellomkanalen 25 ledes nå det flytende kjblemiddel til frysefordamperen 19, der det fordampes slik at frysefaget avkjbles til en meget lavere temperatur enn kjolefaget. Fra frysefordamperen strbmmer nå kjblemidlet, som her som regel er helt fordampet, via samlebeholderen 20 og sugeledningen 21 tilbake til kompressoren. Fordamperen 18 avkjbles under kompressorens gang stadig mer. Temperaturfbleren 37 fra-kopler kompressoren ved en bestemt temperatur gjennom termostaten 39, slik at tvangsmatning av kjblemiddel avbrytes. Det ved avbruddet i kapillarrbret gjenværende kjblemiddel, hvis mengde er meget liten, strbmmer nå i det minste delvis fra rbret inn i fordamperen og fordampes. Gjennom den herved oppstående trykkstigning som gjennom det på det dypeste sted samlede kjblemiddel forhindres fra å trenge frem til frysefordamperen 19, fores derimot det i kjblefordamperen 18 værende kjblemiddel gjennom rbret 24 og mellomkanalen 25 via rbr-bbyen 28 til frysefordamperen og samles der. After the compressor is switched on by the thermostat, it sucks coolant from the freezer evaporator 19 via the suction pipe 21 and presses it to the condenser 12, where it is heated and condensed and flows through the tube 13 further through the capillary tube 14 from above into the coolant evaporator 18 at its highest point. In the slbyfs 17 and 24, the cooling agent begins to boil and partially evaporates, whereby it draws heat from the cooling room, which is thereby cooled. Via the intermediate channel 25, the liquid coolant is now led to the freezing evaporator 19, where it evaporates so that the frozen object is cooled to a much lower temperature than the dressed object. From the freezer evaporator, the cooling agent, which here is usually completely evaporated, now flows via the collection container 20 and the suction line 21 back to the compressor. The evaporator 18 is increasingly disconnected during the operation of the compressor. The temperature switch 37 switches off the compressor at a certain temperature through the thermostat 39, so that forced feeding of coolant is interrupted. The cooling agent remaining at the break in the capillary tube, the amount of which is very small, now at least partially flows from the tube into the evaporator and evaporates. Through the resulting pressure rise, which is prevented by the cooling agent collected in the deepest place from penetrating to the freezing evaporator 19, the cooling agent in the cooling evaporator 18 is, on the other hand, fed through the rib 24 and the intermediate channel 25 via the rib 28 to the freezing evaporator and is collected there.
Diameteren på rbret 24 og kanalen 25 mellom stedene 23 og 28 er således dimensjonert at det opp langs væskesbylen oppstående pneumatiske overtrykk ikke kan trenge forbi spylen men skyver denne foran seg over terskelen 28 inn i frysefordamperen 19, slik at fordamperen 18 helt tommes. The diameter of the rib 24 and the channel 25 between the locations 23 and 28 is dimensioned in such a way that the pneumatic overpressure arising along the liquid plume cannot penetrate past the flush but pushes it in front of it over the threshold 28 into the freezing evaporator 19, so that the evaporator 18 is completely emptied.
Samlebeholderon 20 tjener herved som sikkerhetsrom for at det under stillstand ikke skal komme noe flytende kjblemiddel inn i sugeledningen 21, hvilket ville fore til uønsket kondens-vanndannelse og oke driftsomkostningene. Ettersom fordamperen 18 allerede kort tid etter kompressorens avstengning er helt tom avkjbles den ikke mer, men kan uhindret oppvarmes og avrimes av luften i kjblefaget. Etter avrimingens slutt, som avfbles av temperaturfbleren 37, innkoples igjen kompressoren og sirkulasjonsprosessen gjentas. Collecting container 20 thereby serves as a safety space to ensure that no liquid caulking agent enters the suction line 21 during standstill, which would lead to unwanted condensation and water formation and increase operating costs. As the evaporator 18 is already completely empty shortly after the compressor is switched off, it is no longer de-energized, but can be unhindered and heated and defrosted by the air in the cooling compartment. After the end of the defrosting, which is signaled by the temperature sensor 37, the compressor is switched on again and the circulation process is repeated.
