Problems solved by technology

[0008] These technologies have several disadvantages, such as: high cost of acoustic materials for covering or sealing; need for retrofitting in the compressor, which increases its cost; increase in compressor temperature; reduction in fan efficiency; reduction in efficiency; and the need for additional steps in the process of obtaining the refrigerating device, depending on the need for the process of installing and placing the covering and closing elements of said housing, which encloses the compressor in the refrigerating device

Embodiment Construction

[0045] The present invention provides a technical solution for attenuating the noise generated in the area of ​​the housing 1 defined above. The housing 1 is arranged in the lower rear area of ​​the cabinet 3 of a refrigeration device (for example, a refrigeration device in the form of a refrigerator or a freezer) .

[0046] The housing 1 is defined by a recess in the rear wall 3a of the refrigeration equipment cabinet 3.

[0047] As shown in the figure, the compressor 2 carries an evaporation tray 4, the size of the evaporation tray 4 is designed to be able to receive and store water from the defrosting process of the refrigeration system of the refrigeration equipment, the evaporation tray 4 is of this type , Which is attached to the enclosed housing 2a of the compressor 2 of the refrigeration system.

[0048] In this structural solution, the evaporating plate 4 is placed on the casing 2a of the compressor 2 so that the evaporating plate is heated by the heat generated by the comp...

Abstract

The invention refers to a resonator arrangement for the cabinet of a refrigeration appliance, said cabinet (3) defining a housing (1) and carrying, in the latter, a compressor (2) presenting a hermetic casing (2a) and a defrost water evaporating tray (10) comprising: a bottom wall (11), to be seated onto an upper portion of the casing (2a) of the compressor (2); and a peripheral wall (12) superiorly projecting from the bottom wall (11), at least one of the peripheral wall (12) and bottom wall (11) of the evaporating tray (10) carrying a noise absorbing means turned to a noise generation regionin said housing (1) and being dimensioned to define a certain reactive impedance and a certain dissipative impedance in the medium of the housing (1) for a determined frequency band.

Description

Technical field [0001] The present invention relates to the arrangement of the resonator provided in the cabinet of the refrigeration equipment, especially the arrangement of the resonator provided in the area where the compressor of the refrigeration system of the refrigeration equipment is housed in the cabinet. Noise generated by the operation and / or operation of the fan arranged in this area of ​​the housing. More specifically, the present invention relates to a resonator arrangement provided in a defrosting water evaporating plate of a refrigeration system of a refrigerator appliance, the evaporating plate adopts a type attached to the shell of a hermetic compressor of the refrigeration system. Background technique [0002] The noise emitted by the refrigerator can be confined in two regions of the frequency spectrum: in frequencies below about 2 kHz and in those frequencies above this value. [0003] In the first frequency spectrum area defined by the lower frequency, there ...
