摘要： Gasket for refrigerator cabinets of the kind including a soft bellows-type portion used for sealing the area between the cabinet and the door and extending from a base portion able to match the outer door and/or inner door of the refrigerator cabinet. The base portion is substantially rigid and has at one end, a sealing portion made of substantially soft material extending toward the inner door. The soft material portion has good flexible and spring back features when exposed to refrigerator and freezer temperatures. These features make the gasket able to further seal, preferably by compression, the space located between the cabinet and inner door in a more internal area of the refrigerator cabinet. Furthermore, the soft sealing portion is independent and free from constraints with respect to the soft bellows-type portion.

摘要： A refrigeration circuit (3) for household appliances comprises a compressor (4) suitable for compressing a predetermined cooling fluid and for allowing the circulation thereof within said circuit (3), a first heat exchanger (5) or condenser in fluid communication with the compressor (4) for allowing the cooling and the consequent condensation of the cooling fluid going through, and a second heat exchanger (7) or evaporator in fluid communication with the first exchanger (5) through a circuit with a special device (6) suitable for decreasing the pressure of the cooling fluid at a space (2) to be cooled (normally inside the refrigerator). The second exchanger (7) allows the cooling fluid to evaporate, absorbing heat, thus cooling the space (2) and returning through the tubing (17) to the compressor (4). The cooling fluid circulates from the compressor (4) towards the first exchanger (5), from the latter towards the second exchanger (7) and then returns to the compressor (4) for a subsequent cycle. At least one of the heat exchangers (5, 7) comprises a plastic tubing (9), at least a portion whereof exhibits such corrugated profile as to impart flexibility thereof and/or increase the thermal exchange surface.

摘要： A method and apparatus for heat-welding corners lengths of profiles together, for sealing gaskets, where the profiles include at least one extendible or compressible air chamber and are cut at their ends at an angle. The method includes positioning two profiles, with one of the cut ends of each profile opposite each other inside a suitable device including clamps which make the positioning possible, heating the positioned ends until the positioned ends reach a softened state, choking the profiles so as to completely occlude the air chambers along choking sections, closing the clamps in order to cause the profiles to come into mutual mating contact at the heated ends, injecting air into the air chambers by perforating the air chambers in a region between the choking sections and the heated ends so as to apply pressure to walls of the profiles in that region, pressing the walls against walls of the clamps to join the heated ends by heat-welding under pressure, and opening the occluded sections. The apparatus includes a heating element to heat one of the ends of each profiles, clamps to position the profiles with the cut ends opposite each other and for mutually mating the heated ends together, needles for injecting air inside an interior of the air chambers nearby the ends to be heat-welded, and devices to choke the profiles by completely occluding said air chambers along choking sections.

摘要： A plastic material profile (1) for refrigerators and freezers include a door (30) and an inner door (31) having a bellows gasket (20) portion which provides a seal between the door and the cabinet (32). The profile and the gasket portion are coupled together, or they are just one integral part obtained by coextrusion of two materials having different stiffness in order to allow, when needed, an easy disjunction of the gasket portion from the profile along their connection area, said profile having a groove (23) suitable to receive, in substitution, a bellows gasket portion, said groove (23) being defined by a pair of walls (5) and (5') which extend vertically or obliquely from a base (3), characterized in that said base (3) is shaped substantially as a C-section which can be elastically deformed by means of a soft material elbow (8) obtained by coextrusion on the same section, such elbow thus working as a hinge to allow the elastic enlargement of said C-section, in order to realize the snap engagement of the edge of said inner door (31) inside (19) the section itself, and, externally and below said C-section, of the profile, providing a sealing on the edge of said door (30).
