Sealing system for refrigerator

#This application claims priority to and the benefit of Brazilian Patent Application No. PI1101701-5, filed Apr. 18, 2011, the entire disclosure of which is incorporated herein by reference in its entirety.

#The present invention relates to a sealing system for a refrigerator and, more particularly, to a sealing system located between the doors of a refrigerator and its acclimatized chambers and of the kind that comprises a gasket to be inserted in a receiving channel existing also between the doors of a refrigerator and its acclimatized chambers.

#Sealing the door of the refrigerated compartment of a refrigerator or freezer is essential for grating proper and efficient refrigeration. The inlet of hot air in the generated refrigerated compartment and the outlet of cool air from the same impact the efficiency in pre-serving the refrigeration, the energy consumption (excessive activation of the compressor), and may still cause water formation in the inside and outside of the compartment due to condensation or unwanted ice formation.

#Figures show:

#FIG. 1 illustrates the cross-sectional section of the preferred construction of the gasket belonging to the sealing system for refrigerator;

#FIG. 2 illustrates, in a schematic manner, a first gasket arrangement of FIG. 1;

#According to the concepts of the present invention, it is disclosed a sealing system for refrigerator comprising at least one gasket 1, which is disposed between at least one movable door 2 and at least one fixed cabinet 3. The gasket 1 is intended to prevent escape of fluids (in this case, air) existing within an acclimatized chamber to the external environment, while it also has the function of preventing the inlet of external fluids within a refrigerated chamber. That is, the gasket 1 has the function of sealing, in a hermetic manner, the internal environment of a refrigerated chamber from the external environment.

#Said gasket 1 can be attached to the movable door 2, or further to the fixed cabinet 3. The movable door 2, which preferably belongs to a refrigerator (not shown) is preferably attached in a pivoting manner to the fixed cabinet 3.

#According to the proposed in the present invention, the novelties evinced herein provide two different aspects, namely: interaction of gasket 1 with the movable door 2, and interaction of gasket 1 with the fixed cabinet 3. In this context, it is ascertained that the gasket 1 is preferably made of a material having mechanical resiliency, such as elastomers or polymers.
