Description

Machine room separate type refrigerator

The present invention relates to a refrigerator, and more particularly, to a machine room detachable refrigerator capable of mounting the machine room of a refrigerator including a compressor, a condenser, and the like outdoors.

In general, a refrigerator is a device that keeps food fresh for a certain period of time by reducing the temperature in the refrigerator as the refrigerant is repeatedly compressed, condensed, expanded, and evaporated.

Such a refrigerator includes a compressor for raising / heating a low temperature / low pressure gas refrigerant to a high temperature / high pressure gas refrigerant, a condenser for condensing the refrigerant introduced from the compressor by outside air, and a narrow diameter compared to the diameter of other parts. It consists of an expansion valve for reducing the refrigerant introduced from the condenser, and the evaporator which absorbs the heat in the refrigerator as the refrigerant passing through the expansion valve in a low pressure state as a basic component constitutes a refrigeration cycle.

Hereinafter, a structure and an operation of a general refrigerator will be described with reference to the accompanying drawings.

As shown in FIG. 1, the refrigerator includes a freezer compartment 2 in which cold air heat-exchanged by the evaporator 17 is directly introduced into the case 1 to maintain an internal temperature of about −18 ° C., and the freezer compartment. The cold air inside is largely divided into a refrigerating chamber which maintains an internal temperature of about 0-7 ° C., and a machine room 3 is provided under the rear of the freezing chamber.

And the rear of the freezing chamber (2) is provided with a cold air duct (5) through which the hot air is introduced for heat exchange while circulating the freezer compartment and the refrigerating compartment, and the cold air duct along with the evaporator (17) through the evaporator to lower the temperature A blowing fan 18 for forcibly circulating the cold air to the freezing chamber 2 and a motor for driving the blowing fan are provided.

Meanwhile, although not shown in the drawing, the case 1 is divided into a freezing compartment 2 and a refrigerating compartment by a barrier, and the barrier 1 is formed with a plurality of communication ports through which free air of the freezing compartment and the refrigerating compartment can be freely exchanged. Is supplied to the refrigerating compartment and the cold air of the refrigerating compartment may be introduced into the cold air duct (5) through the freezing compartment.

The machine room 3 includes a plurality of components constituting a refrigeration cycle together with an evaporator, that is, a compressor and a condenser, and at the same time, radiates heat by forcibly blowing heat generated from the inside of the machine room, in particular, the heat generated from the condenser. The fan is further provided.

The refrigerator configured as described above is operated by receiving a control signal from a controller (not shown) in the freezer compartment 2 and the refrigerating compartment when power is applied, and the evaporator 17 is operated by the refrigerating cycle as described above. Heat exchange environment is created. Therefore, the cold air passing through the evaporator is lowered by the endothermic action, and is discharged to the refrigerating chamber 2 by the operation of the blower fan 18. Subsequently, some of the cold air is introduced into the refrigerating chamber through the cold air communication port. Thereafter, the cold air, which has been heated while circulating in the freezing chamber 2 and the refrigerating chamber, forms a cold air circulation structure introduced into the evaporator 17 through the cold air inlet again.

However, considerable noise and vibration are generated in the compressor of the machine room 3 during operation of the refrigerator as described above. In particular, due to the fact that most of the refrigerators are installed indoors, noise and vibration generated at night cause a significant burden on the user.

And the machine room (3) has a considerable volume, which results in a significant reduction in the internal volume to accommodate the object in the refrigerator.

On the other hand, the main occurrence of the failure in the refrigerator is the various components that make up the refrigeration cycle. In particular, when a component of the machine room such as a compressor or a condenser breaks down, it needs to be replaced. For this purpose, the inconvenience of having to remove the entire case 1 of the refrigerator or move the entire refrigerator.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a machine room separated refrigerator which is advantageous for securing an interior volume while providing a comfortable operating environment by separating a machine room equipped with a compressor.
