Abstract

PROBLEM TO BE SOLVED: To improve rigidity of a supply air duct in vertical and lateral directions and to reduce vibration of the duct and noise of a fan lay providing ribs a cooler cover at an air duct side and bringing it into contact with air duct surface of a partition material in vertical and lateral directions. SOLUTION: In a refrigerator body 1, form heat insulator 4 is filled in a space formed of an outer case 2 and an inner case 3, and a cooler 6 and a blower 7 are disposed on a back part of a deep freezing chamber 5. Cold air formed by the cooler 6 is supplied to the chamber 5 and a cold storage chamber 9 via a supply air duct 8 constituted by a cooler cover 10 and partition material 13. In this case, upper and lower protrusion ribs 11 of vertical directions and right and left protrusion ribs 12 of lateral directions of the air duct side are provided on the cover 10, and brought into contact with the air duct surface of the material 13 in the vertical and lateral directions. Thus, since rigidities of the duct 8 in the vertical and lateral directions are improved and another component may not be added to reduce fan noise, fan noise reducing effect of the refrigerator is obtained with a low cost.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation duct for a fan-cooled refrigerator, freezer, or the like.

[0002]

2. Description of the Related Art In recent years, in fan-cooled refrigerators and freezers, a cooler is provided at the back of a freezing room, and cool air cooled by the cooler is sent into each room through a blower duct by a blower. The room is being cooled. However, since the cool air from the blower is directly blown to the blow duct, the blow duct vibrates and causes an increase in fan noise. Therefore, as a method for improving these problems, for example, a method disclosed in Japanese Patent Application Laid-Open No. 3-274366 has been proposed.

Hereinafter, an example of the above-described refrigerator will be described with reference to the drawings. FIG. 4 is a sectional view of a conventional refrigerator. In FIG. 4, reference numeral 1 denotes a refrigerator main body, and a space formed by an outer box 2 and an inner box 3 is filled with a foamed heat insulating material 4. Reference numeral 5 denotes a freezing room, and a cooler 6
The blower 7 is arranged on the upper part. Cooler 6
The cool air produced by the blower is blown from the blower 7 and the cooler 5
Cool air is supplied to the freezer compartment 5 by the ventilation duct 8 arranged in front of the
And sent to the refrigerator compartment 9. The air duct 8 includes a cooler cover 10 and a partition member 13. Further, at a position on the front of the blower 7 in the cooler cover 10,
A soft tape 14 as a heat insulating member is provided. As shown in FIGS. 5 and 6, a plurality of bosses 15 are erected on the upper rear surface of the cooler cover 10, and holes 16 formed in the soft tape 14 are fitted into the bosses 15.
Thereby, the soft tape 14 is attached to the cooler cover 10. An annular bush nut 17 is fitted over the boss 15 protruding from the soft tape 14. Here, the bush nut 17 has a conical cut and raised portion formed inside the annular flange portion 18, and when the bush nut 17 is fitted to the boss 15, the cut and raised portion strongly bites into the boss 15, and the soft tape 14 comes off. Has been prevented. Here, since the soft tape 14 has a sound absorbing property, fan noise from the blower 7 can be absorbed by the soft tape 14, thereby reducing the noise.

[0004]

However, in the above-described configuration, the blower duct 8 requires a separate component other than the cooler cover 10 and the partition member 13 in order to reduce the noise of the blower 7, which increases the cost. There were drawbacks.

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a refrigerator that can reduce noise of a blower at low cost.

[0006]

In order to achieve the above object, the present invention provides a structure in which a rib is provided on the air path side of a cooler cover so that the rib is brought into contact with the air path surface of the partition member in the vertical and horizontal directions. It is.

As a result, the rigidity of the air duct in the vertical and horizontal directions is improved, vibration of the air duct is reduced, and fan noise can be reduced. In addition, the cost can be reduced without requiring a separate component other than the cooler cover and the partition member.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention provides an outer box, an inner box, a foam insulation material filled between the two boxes, a freezer compartment formed by the inner box, and a cooler attached to the inner part of the freezer compartment. A blower attached to the top of the cooler, a blower duct that guides cool air blown to the front of the cooler into the refrigerator compartment, the blower duct has a cooler cover having protruding ribs, and for heat insulation of the cooler. A refrigerator, characterized in that the projecting ribs of the cooler cover and the air path surface of the partition material are abutted in the vertical and horizontal directions, in addition to the cooler cover and the partition material in the air duct. Without the need for separate parts
The fan noise of the refrigerator can be reduced at low cost.

[0009]

FIG. 1, FIG. 2 and FIG.
This will be described with reference to FIG. To avoid duplication of explanation,
The same components as those of the conventional example are denoted by the same reference numerals, and detailed description thereof will be omitted.

(Embodiment 1) FIG. 1 is a cross-sectional view of this embodiment, which reduces the fan noise of a refrigerator at low cost without requiring a separate part other than a cooler cover and a partition member in an air duct. As shown in FIGS. 2 and 3, reference numeral 10 denotes a cooler cover, which has a vertically protruding rib 11 in the vertical direction on the air path side and a left and right protruding rib 12 in the horizontal direction.
The partition 13 is brought into contact with the air path surface in the vertical and horizontal directions.

[0011]

As described above, according to the present invention, the projecting ribs are provided on the air path side of the cooler cover in the vertical direction and the horizontal direction, and are brought into contact with the air path surface of the partition member. The rigidity in the direction is improved, and there is no need to add another component for reducing the fan noise, so that the effect of reducing the fan noise of the refrigerator can be obtained at low cost.
