Abstract

PURPOSE:To diminish noise and avoid uneven distribution of coldness in freezing and refrigerating compartments and a reduction in refrigerating performance by a method wherein a fan is enclosed in a cooler cover and the periphery part of a hole in the cooler cover, which surrounds the fan, has a thickness larger than that of the adjacent part. CONSTITUTION:The cold air is generated by a cooler 4 and discharged by a fan 6 through a hole 19 in a cooler cover 18. The cold air is distributed to an air port 15 and air outlets 13 by a protruding rub 10 on the cooler cover 18 and respectively led to and circulated through refrigerating compartment and a freezing compartment where heat exchange takes place. After that, the wet air is induced by the fan 4 and turned to cold dry air by heat exchanging while it flows through the cooler 4 from bottom to top. The hole 19 is provided in the cooler cover 18 so as to surround the fan 6 and its periphery part has a flange-like shape and a thickness thicker than the adjacent part. Therefore, as the periphery part has a larger mass and is enhanced in rigidity, the periphery part of the hole 19 provided on the cooler cover 18 is prevented from vibrating and producing noise. Moreover, as a clearance is prevented from being created between the protruding rib 10 and a contact face 17 of a grille 12, problems such as uneven distribution of coldness in the freezing and refrigerating compartments and a reduction in the refrigerating performance do not occur.

A cooler 4 is installed at the back of the freezer compartment 6, and above it a blower 6 is attached with mounting screws 7. Reference numeral 8 designates a cooler cover made of synthetic resin, which surrounds the air blower va 6 and has a hole 9 with a flange-shaped end, and directs the cold air coming out from the hole 9 to the end of the cooler cover 8. It has a protruding lip 19 for guiding, a recess 11, and an air intake port from inside the freezer compartment 6, and is installed on the front and side surfaces of the cooler 4. A grill 12 is made of synthetic resin, has a cold air outlet 13 into the freezer compartment 6, and is installed on the front surface of the cooler cover 8. Further, the air outlet 1 that guides cold air to the refrigerator compartment by the cooler cover 8 and the grill μ
6 is formed.

The operation of the refrigerator configured as described above will be explained below. First, the cold air generated in the cooler 4 is passed through the hole 9 of the cooler cover 8 by the blower 6 as shown by the arrow in FIG. Then, some of the air passes through all 16 air vents and flows into the refrigerator compartment. In addition, the cold air that circulates through the freezer compartment and exchanges heat with the stored items is passed through the intake port 14. The cold air that has circulated through the refrigerator compartment and exchanged heat with the stored items is guided below the cooler 4 by separately provided ducts 16, and when sucked upward by the blower 6,
It performs heat exchange with the cooler 4. The cold air that has passed through the hole 9 reaches the lip 1o and the lip 1o protruding from the cooler cover 8! At the contact surface 17 of J/l/12, it is distributed to the freezer compartment and the refrigerator compartment.

Problems to be Solved by the Invention However, in the above configuration, when the cold air cooled by the cooler 4 is discharged during the rotation of the air blower @e during refrigerator operation, the end portion provided on the cooler cover 8 is There were problems such as the area around the flange-shaped hole vibrating and generating noise. Also this evening, the cooler cover 8! j/l
If the mounting part 12 becomes loose, the lip 10 protruding from the cooler cover 8 and the contact surface 17 of the grill 12 will not come into contact with each other, and when a gap occurs, cold air will protrude into the freezer and refrigerator compartments. It leaks from the middle of 1° depending on the load in the freezer and refrigerator compartments.

Because of the inflow, the cooling of the freezer and refrigerator compartments varied, the cooling was slow, and the reliability was lacking.

In view of the above-mentioned problems, the present invention prevents noise by eliminating vibrations around the hole provided in the cooler cover, and also solves problems such as uneven cooling of the freezer compartment and refrigerator compartment, and slow cooling. The purpose is to

Means for Solving the Problems For the above purpose, the refrigerator of the present invention includes a cooler installed at the back of the freezer compartment, and a blower installed at the top of the cooler for forced circulation of cold air cooled by the cooler. , a cooler cover having a hole disposed on the side and front side of the cooler, surrounding the blower, having a flange-shaped end, and having a thicker plate thickness at the end than the surrounding area; It consists of a grill placed on the front of the cooler cover.

Effects According to the above-described configuration, the thickness of the end of the hole surrounding the blower provided in the cooler cover is thicker than the surrounding area, so that the mass is increased and the rigidity is increased. This eliminates vibrations around the hole provided in the cooler cover to prevent noise, and also solves problems such as uneven cooling of the freezer compartment and refrigerator compartment, and slow cooling.

EXAMPLE Hereinafter, a refrigerator according to an example of the present invention will be described with reference to the drawings.
