  • This seal has pressure adjustment holes at certain points facing the inside and outside of the refrigerator. Air flows through the holes from outside the refrigerator, where the pressure is high, into the interior of the refrigerator, where the pressure is low, and this flow continues until the pressure is equalized.
  • the patent application FR2445916 provides an embodiment of a seal which facilitates the opening of the refrigerator door. Accordingly, a longitudinally extending space is defined between the leg and the connecting parts. At both ends of the longitudinally extending space there is a transverse passage. During the first passage the longitudinal space with the
  • the second passage connects it to the interior environment.
  • the operation is as follows. As a result of the vacuum created by closing the door, the air of the outside environment reaches the longitudinal space through the first passage; from there it enters the interior through the second passage. This airflow eliminates the generated pressure drop, and thus the door can be easily opened.

Therefore, if there is a negative pressure in the refrigerator, an air flow from the outside environment (30) is realized inwardly, and thereby the pressure difference is compensated in a short time.

Abstract

La présente invention concerne un appareil frigorifique (10) comprenant un corps (11), un compartiment intérieur (13) défini à l'intérieur de ce dernier, une porte (12) fermant le compartiment intérieur (13) et un canal d'étanchéité (25), une garniture d'étanchéité (20) comportant au moins une ouverture (251) sur une partie, orientée vers l'environnement extérieur (30), de l'appareil frigorifique (10), et au moins une ouverture (262) sur une partie, orientée vers l'environnement intérieur (13), de l'appareil frigorifique (10). L'objet de l'invention est amélioré en ce que la garniture d'étanchéité comprend une lèvre (261) qui, une fois la porte (12) fermée, interrompt le courant d'air entre le compartiment intérieur (13) et l'environnement extérieur (30) à travers le canal d'étanchéité (25) et les ouvertures (251, 262) et qui, lorsque la porte (12) est ouverte, s'étend à l'intérieur du canal d'étanchéité (25) pour permettre ainsi le passage du courant d'air lors d'un changement de forme de la garniture d'étanchéité (20).
