Abstract

Freezers and refrigerators in which the cooling is carried out by chilled air piping with a defined shape, in the thickness of the insulating walls, the usual freon pipes supplying this air via the draught from a fan. The latter is arranged vertically in order to lighten the rotor by reaction. Defrosting is carried out by stopping the fans. Extraction of the water is automatic. The compartments have walls which are externally and horizontally corrugated in order to reduce losses by convection. Their walls can be completely dismantled and their dimensions can be much larger than those of usual appliances. They have self-levelling feet.

Description

PERFECTIONNEMENTS DE LA STRUCTURE ET DU FONCTIONNEMENT DES CONGELATURES
ET REFRIGERATEURS DOMESTIQUES.IMPROVEMENTS IN THE STRUCTURE AND FUNCTIONING OF FREEZING
AND DOMESTIC REFRIGERATORS.

Les réfrigératuers et congélateurs domestiques sont généralement refroidis directement par les tubes de l'évaporateur dans lesquels se détend le fluide frigorigène,en général du fréon,souvent noyés dans l@solant (Fig.1-I-),côté ouve(Fig.1-2-),àlaquelle le froid est communiqué par contact direct.Parfois,ils sont fixés dans les ouves,et soumis ou non à un courant d'air de brazsaga.  Household refrigerators and freezers are generally cooled directly by the evaporator tubes in which the refrigerant, in general freon, expands, often embedded in the solant (Fig.1-I -), opening side (Fig.1 -2 -), to which the cold is communicated by direct contact. Sometimes, they are fixed in the openings, and subjected or not to a draft of brazsaga air.

Il a déjà été envisagé de remplacer ces tubes par des canaux dans lesquels circulerait de l'air glace produit par les tubes de fréon regroupés et sou- mis à l'action d'un ventilateur.It has already been envisaged to replace these tubes with channels in which ice air produced by the freon tubes grouped together and subjected to the action of a fan would circulate.

Ce système n'a pas été utilisé,ou de façon confidentielle,dans les appareils domestiques,probalement à cause de la durée trop limitée des ventilateurs, des difficultés du dégivrage,de l'étanchéité aléatoire des bacs à double @@ paroi,et d'une structure générale incompatible avec une fabrication économique,cette énumération n'étant pas limitative.This system has not been used, or in a confidential manner, in domestic appliances, probably because of the too limited duration of the fans, the difficulties of defrosting, the random watertightness of the double @@ wall tanks, and d 'A general structure incompatible with economical manufacturing, this list is not exhaustive.

Le but de la présente demande de brevet est d'éliminer les inconvénients précédents,pour tirer parti de l'avantage principal du système:l'indépendance du générateur frigorifiques.The purpose of this patent application is to eliminate the above drawbacks, to take advantage of the main advantage of the system: the independence of the refrigeration generator.

NOTRE SOLUTION. Le congélateur amélioré est conçu de la façon suivante: 1) La ouve à double cloison,simple ou crénelée,est remplacée par des canaux dé forme particulière(Fig.2-3-) moulés dans une mousse isolante rigide, au moment de son injection.Leur section est profonde et étroite pour éviter la déformation de la ouve(Fig.2-3-)chargée de marchandises,sans l'épaissir.OUR SOLUTION. The improved freezer is designed as follows: 1) The double-walled opening, simple or crenellated, is replaced by channels of particular shape (Fig. 2-3-) molded in rigid insulating foam, at the time of its injection Their section is deep and narrow to avoid deformation of the opening (Fig. 2-3) loaded with goods, without thickening it.

2) L'ensemble frigorifique(Fig.3-E-)est installé pendulairement(A-Fig.3-5-) dans une alvéole située dans les coffres,sur la couronne d'étanchéité(13-
Fig.5-)séparant obligatoirement le condenseur(9) et le compresseur(10-Fig.5) de l'évaporateur(6).Cette étanchéité,capitale,ne dépend donc pas d'un serrage de boulon ou d'une perte d'élasticité d'un bourrage.2) The refrigeration unit (Fig.3-E-) is installed pendularly (A-Fig.3-5-) in a cell located in the boxes, on the sealing ring (13-
Fig. 5-) obligatorily separating the condenser (9) and the compressor (10-Fig. 5) from the evaporator (6). elasticity of a jam.

Le 3) ventilateur(8)refroidissant le condenseur (9),le compresseur(10),et son @@@ propre moteur(Fig.5-) ) est vertical et chasse l'air de ventilation vers le bas.La réaction de l'hélice soulage ainsi les paliers,l'anneau de garde 11
Fig.5-étant rétréci pour augmenter l'allègement du rotor par effet de proximité.The 3) fan (8) cooling the condenser (9), the compressor (10), and its own motor (Fig. 5-)) is vertical and expels the ventilation air downwards. the propeller thus relieves the bearings, the guard ring 11
Fig.5-being narrowed to increase the lighter weight of the rotor by proximity effect.

4)Une turbine(Fig.5-et Fig.3-5),calé@ sur l'arbre du ventilateur (Fig.3).4) A turbine (Fig.5- and Fig.3-5), wedged @ on the fan shaft (Fig.3).

refoule dans les canaux en circuit fermé(Fig.3-7-)l'air aspiré à travers l'évaporateur (6-Fig.3 et 5),qui l'a refroidi.discharges the air drawn through the evaporator (6-Fig. 3 and 5), which has cooled it, into the closed-circuit channels (Fig. 3-7-).

5) L'ensemble turbine-volute et ventilateur constitue un groupe(12-Fig.4) amovible,mécaniquement indépendant du circuit frigorifique,et facilite la fabrication.5) The turbine-volute and fan assembly constitutes a removable group (12-Fig. 4), mechanically independent of the refrigeration circuit, and facilitates manufacture.

6) L'air glacé circulant en circuit fermé entre le générateur de froid -Fig.3-E-et les canaux (7) du coffre de conservation (C)-Fig.3-,subit à chaque cycle de fonctionnement,des variation de température,donc de volume.6) The icy air circulating in a closed circuit between the cold generator -Fig.3-E- and the channels (7) of the preservation box (C) -Fig.3-, undergoes variations at each operating cycle of temperature, therefore of volume.

Il y a ainsi un va et vient d'une petite quantité d'air extérieur qui pro.There is thus a comings and goings of a small quantity of outside air which pro.

voquerait à la longue le givrage complet de l'évaporateur,l'étanchéité n'étant pas absolue,toujours pour des raisons d'économie.in the long run would evoke the complete icing of the evaporator, the sealing not being absolute, always for reasons of economy.

Le dégivrage indispensable et peu fréquent est déclanché manuellement au moyen d'un thermostat(34-Fig.5-)placé à proximité de l'évaporateur.Il arrête les ventilateurs,et pas le compresseur.Le condenseur-9-n'étant plus refroidi,la température de l'évaporateur-6-devient positive,et le givrefond.The essential and infrequent defrosting is manually triggered by means of a thermostat (34-Fig.5-) placed near the evaporator. It stops the fans, not the compressor. The condenser-9-is no longer cooled, the temperature of the evaporator-6-becomes positive, and the frost melts.

L'eau produite se dépose dans un bac en couronne(19)-Fig.5-audessus du corps de la turbine-5-Elle est évacuée par un tube-T-Fig.5-dont l'extrémité (20-fig.5-) souple et aplatie se referme après le passage de l'eau,sous l'effet@upplémentaire de la légère dépression provoquée par la position de l'entrée du tube dans la zone d'aspiration(24-Fig.5-) de la turbine(5).The water produced is deposited in a ring tank (19) -Fig.5-above the turbine body-5-It is evacuated by a tube-T-Fig.5-whose end (20-fig. 5-) flexible and flattened closes after the passage of the water, under the additional effect of the slight depression caused by the position of the entry of the tube in the suction zone (24-Fig.5-) of the turbine (5).

(21)
Cette eau est recueillie dans une coupe(22)Fig.5-sous le congélateur et s'évapore sous l'effet de l'air du ventilateur
Quand le givre est fondu,le thermostat de dégivrage rétablit automatique- tent le courant électrique des ventilateurs,et le froid revient.(21)
This water is collected in a cup (22) Fig. 5-under the freezer and evaporates under the effect of air from the fan
When the frost has melted, the defrost thermostat automatically restores the electric current to the fans, and the cold returns.

7) Les habituelles parois lisses de la jupe(Fig.6-25-)facilitent la circulation de l'air ambiant(35-Fig.6)descendant le long du coffre (25) qu'il réchauf chauffe.Cela correspond à la consommation d'énergie"en conservateur".7) The usual smooth walls of the skirt (Fig. 6-25-) facilitate the circulation of ambient air (35-Fig. 6) descending along the trunk (25) which it heats up. This corresponds to the "conservative" energy consumption.

Cette perte peut être diminuée par des nervures transversalcs(17-Fig.9-)
si possible horizontales(Fig.10-18-),de profils divers (Fig. 7 et 8-)et choisis pour perturber l'écoulement de l'air au maximum,et le ralentir.This loss can be reduced by transverse ribs (17-Fig. 9-)
if possible horizontal (Fig. 10-18 -), of various profiles (Fig. 7 and 8-) and chosen to disturb the air flow as much as possible, and slow it down.

8) Lorsque les congélateurs-coffres sont lourdement chargés,et que le cala- ge des pieds est aauvais,ils peuvent se voiler à la longue,ce qui fait bailler le couvercle et compromet la durée des appareils.Nous supprimons ce risque en remplaçant deux des pieds par les extrémités arrondies dune barre rigide,pliées en sens inverse,en forme de manivelle(Fig.11 et
Cette barre(30) peut osciller sous le poids de l'appareil;les extrémités 31 et 32 formant deux leviers opposés,décalés angulairement,peuvent donc porter sur le sol en des endroits 36 et 37 de niveaux différents.La stabi-
lité est donc assurée par les 4 pieds,même avec un sol irrigulier. 8) When the chest freezers are heavily loaded, and the setting of the feet is poor, they can cloud over time, which makes the lid yawn and compromises the life of the appliances. We eliminate this risk by replacing two feet by the rounded ends of a rigid bar, bent in opposite directions, in the form of a crank (Fig. 11 and
This bar (30) can oscillate under the weight of the device; the ends 31 and 32 forming two opposite levers, angularly offset, can therefore bear on the ground in places 36 and 37 of different levels.
The bed is therefore assured by the 4 feet, even with an irrigated soil.

9) Une zone de congélation rapide(Fig.14-28-)existe ipso-facto à cô té de
l'alvéole contenant le groupe frigorifique-E-Fig.3-)la paroi métallique
(26-Fig.13-) entourant l'évaporateur(6) étant directement en contact avec
l'air glacé.Elle est délimitée par une cloison légère((27-Fig.14-),amovible pour faciliter le nettoyage.9) A rapid freezing zone (Fig. 14-28-) exists ipso-facto next to
the cell containing the refrigeration unit-E-Fig. 3) the metal wall
(26-Fig.13-) surrounding the evaporator (6) being directly in contact with
the icy air. It is delimited by a light partition ((27-Fig. 14 -), removable to facilitate cleaning.

10) L'absence des tubes de gaz frigorigène noyas dans les parois des coffres et soudés au compresseur permet de rendre démontables toutes les pa- rois des coffres,l'étanchéité des canaux dtair étant facile à réaliser au remontage.Des tiges filetées aux deux bouts(Fig.15 et 16-29-) suffisent
à assurer la cohésion de l'ensemble.Les avantages sont importants.10) The absence of tubes of refrigerant gas embedded in the walls of the boxes and welded to the compressor makes it possible to make all the walls of the boxes removable, the sealing of the air channels being easy to reassemble. ends (Fig. 15 and 16-29-) are sufficient
the cohesion of the whole. The advantages are important.

(I) Pour l,expedition à distance,le volume(Fig.18-) des appareils est réduit de moitié,ce qui perret de doubler la charge d'un conteneur,par exemple.(I) For remote shipping, the volume (Fig. 18-) of the devices is reduced by half, which makes it possible to double the load of a container, for example.

(2) Pour les appareils de grand volume,le démontage permet de paaser de champ dans toutes les portes.(Fig.17-).(2) For large volume devices, disassembly allows the field to be closed in all the doors (Fig.17-).

I1 faut renarquer que les passages @umérotés 2,3,7 et 8 sont applicables aux congélateurs et réfrigérateurs classiques,sàns air intermédiaire.  It should be noted that the passages numbered 2,3,7 and 8 are applicable to conventional freezers and refrigerators, without intermediate air.
