Abstract

PURPOSE:To make it possible to separate an air flow which cools a condenser and a compressor and hence carry out more efficient cooling by dividing a machine chamber whose ceiling side is slanted upward on the rear side into two sections or the front side and the rear side by means of a specific partitioning wall, and installing a condenser and a first ventilation port on the front side, and a compressor and a second ventilation port and a third ventilation port on the rear side. CONSTITUTION:When a compressor 8 is operated to carry out cooling operation, the heat of operation is generated in the compressor 8 and a condenser 11. When the condenser 11 generates heat, an air flow A, which blows out from a ventilation port 17 on the side of the condenser to a ventilation port 19 for a cover section, is formed in a machine chamber 4. When the compressor 8 generates heat, an air flow B, which blows out from a ventilation port 18 for a base section to the ventilation port 19, is arranged to flow when the hot air flow A is discharged from the machine chamber 4 by a partitioning wall 13 while the compressor 8 is cooled by the less hot air flow B. Moreover, the partitioning wall 13 is positioned behind the start section 7 of the slanting side 6 of the ceiling side 5, and provides a rise section 14a. This construction makes it possible to promote the air flow A by tunnel effect where the slanting section 6 is placed near a slanting section 14b on the whole at a proper span and hence enhance the cooling performance of the condenser 11.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a refrigerator mainly used for home use.

BACKGROUND OF THE INVENTION In order to improve cooling performance, refrigerators used at home have been equipped with a method of separating air flows for cooling a condenser and a compressor.

As a conventional technique for separating the airflow for cooling the condenser and the compressor, for example, as shown in Japanese Utility Model Application No. 134571, the compressor is placed in the lower machine room of the refrigerator body, and Some refrigerators are equipped with a separating material on the back of the refrigerator body to separate the air flow that cools the compressor from the air flow that cools the condenser.

In the above configuration, the airflow that has cooled the compressor does not flow to the condenser due to the separation material, and the airflow flows to the condenser without receiving heat from the compressor. Therefore, the condenser can be efficiently cooled and the cooling performance can be improved. Improvements can be made.

Problems to be Solved by the Invention However, in recent years, it has become necessary to provide a cover at the rear of the refrigerator machine room from the viewpoint of aesthetics and soundproofing, and in this case, how to separate the airflow has become a problem. In view of this problem, the aim is to improve the cooling performance of refrigerators by separating the airflow that cools the condenser and compressor to efficiently cool the condenser and compressor.

Means for Solving the Problems In order to solve the above problems, the refrigerator of the present invention has a machine room located at the bottom of the refrigerator main body, the ceiling surface of which is inclined upward on the rear side. The room is partitioned into two areas, a front side and a rear side, by a partition wall which is separated from the ceiling surface of the room and whose upper end side slopes rearward at least, and which is located rearward from the beginning of the slope of the ceiling surface. A condenser is arranged on the front side, and a first vent is provided, and a compressor is arranged on the rear side, and a second vent located below the compressor and a third vent located on the rear side are provided. It is prepared.

Effect: With the above-described configuration, the present invention is capable of separating the airflow for cooling the condenser and compressor even when a cover is provided at the rear of the refrigerator machine compartment, thereby achieving efficient cooling of the condenser and compressor. It is.

Embodiment Hereinafter, an embodiment of the refrigerator of the present invention will be described with reference to the drawings.

FIGS. 1 to 3 show an embodiment of the refrigerator of the present invention. In FIG. 0, 1 is a refrigerator main body made of an insulating box with a refrigerating compartment 2 and a refrigerating compartment 3 inside. Reference numeral 4 designates a machine room, and the ceiling surface 5 has an upwardly inclined inclined surface 6 on the rear side, and the starting point t-7 of this inclined surface 6 is defined as a starting point t-7. 8 is a compressor, 9 is a base that supports this compressor 8, and 10 is a cover. 11 is a condenser, and 12 is an evaporating dish. 1
Reference numeral 3 denotes a partition wall, which is located behind the starting part 7 of the inclined surface 6 of the ceiling surface 5, and the substantially vertical rising part 14a and the inclined surface 6 are inclined rearward in substantially parallel without contacting each other. Part 14
It has b. 2 in the machine room 4 by the partition wall 13
Of the chambers divided into two, the condenser side is a condenser chamber 15,
The compressor side is defined as a compressor chamber 16. The front and lower sides of both sides of the condenser chamber 15 communicate with the outside, and these communicating portions are collectively referred to as the condenser side vent 17. A plurality of base vent holes 18 are provided below the compressor 8 of the base 9, and cover part vent holes 19 are provided at the upper portions of both ends of the cover.

The operation of the refrigerator configured as above will be explained below. When the compressor 8 is operated and a cooling operation is performed, operating heat is generated in the condenser 11 as well as the compressor 8. As the condenser 11 generates heat, a first gas is generated in the machine room 4.
As shown by arrow A in the figure, air mA is formed which escapes from the condenser side vent 17 to the cover partial vent 19. on the other hand,
As the compressor 8 generates heat, an air flow B flows from the pace part vent 18 to the cover part vent 19 as shown by arrow B. At this time, the air IA warmed by the condenser 11 is discharged from the machine room 4 by the partition wall 13 without passing through the compressor 8, and the compressor 8 is heated by the air flow B that has not been warmed in the previous stage by the condenser 11. cooled down. Therefore, the compressor 8 can be cooled more efficiently than when there is no partition wall 13, and the cooling performance of the refrigerator can be improved.

Moreover, since the partition wall 13 is located rearward from the starting part 7 of the inclined surface 6 of the ceiling surface 5 and has an upright part 14a, the inclined part 1
The entire structure 4b can be placed close to the inclined surface 6 at an appropriate distance, and the chimney effect can promote the flow of air and people. Therefore, the cooling performance of the condenser 11 can be improved, and the cooling performance of the refrigerator can be improved. Furthermore, by providing the base vent 18 in the lower part of the compressor 8, most of the airflow A passes around the compressor 8, so the compressor 8 can be efficiently cooled, and the refrigerator The performance of the cold section can be improved.

Moreover, since the noise of the compressor 8 is not directly radiated to the front part by the partition wall 13, the noise can also be reduced.

Effects of the Invention As described above, the present invention provides a machine room which is located at the lower part of the refrigerator main body and whose ceiling surface slopes upward on the rear side, which runs substantially perpendicularly in the front-rear direction and whose upper end is away from the ceiling surface of the machine room at least at the upper end. A partition wall located behind the starting point of the slope of the ceiling surface whose side slopes toward the rear side divides the ceiling into two parts, a front side and a rear side, and a condenser is placed on the front side of these. By providing a first vent with a first air vent, a compressor on the rear side, a second vent located below the compressor, and an eighth vent located on the rear side, condensation can be achieved. In addition to separating the airflow that cools the equipment and the airflow that cools the compressor, it also promotes an increase in the flow rate of the airflow that cools the condenser and improves the cooling efficiency of the airflow that cools the compressor. The cooling performance of the refrigerator can be improved.
