Description

Refrigerator

The present invention relates to a refrigerator, and more particularly, to a refrigerator in which a plurality of intake pipes are provided on a heat sink of the refrigerator and a discharge pipe connected to the intake pipe is formed to facilitate cleaning of the heat sink of the refrigerator.

In general, most homes have refrigerators so that food and beverages can be stored refrigerated or frozen, and ice is also provided.

Such a general refrigerator includes a cabinet 1 having a refrigerator compartment and a freezer compartment as shown in FIG. 1, and a door 2 for opening and closing the refrigerator compartment and the freezer compartment of the cabinet, respectively.

In addition, a lower portion of the rear surface of the cabinet (1) is formed with a machine chamber (3), the refrigerant flow path tube (4) through which the refrigerant pressurized by the compressor installed in the machine chamber 3 is bent.

On the other hand, the coolant channel 4 is provided with a heat dissipation plate 5 for dissipating heat generated while the coolant circulates through the pipe, as well as shielding the coolant channel.

Such a refrigerator is generally disposed at a corner of a home, and the heat sink 5 is positioned at a predetermined distance from a wall of the home so that the refrigerator is not exposed to the outside of the refrigerator.

Meanwhile, a space is formed between the cabinet 1 and the heat sink 5 of the refrigerator, so that dust or foreign matter enters and is attached to or fixed to the refrigerant flow pipe 4, thereby blocking heat dissipation from the refrigerant flow pipe. There was a problem of lowering the efficiency of the refrigerator.

Accordingly, in each home it is necessary to periodically clean the heat sink of the refrigerator after a certain period of time, such a vacuum is used for cleaning.

However, there is a problem that the back of the refrigerator is close to the wall and its space is difficult to clean.

In addition, in order to clean the refrigerator easily and reliably, there was an inconvenience of moving the refrigerator.

Accordingly, the present invention has been made to solve the above problems and inconveniences, and an object of the present invention is to provide a refrigerator that can easily clean the refrigerant flow path and the heat sink or thick plate.

Another object of the present invention is to provide a refrigerator that can easily clean the refrigerant flow pipe and the heat sink to increase the heat dissipation efficiency as well as to improve the refrigerating / freezing efficiency.

These objects are achieved by the present invention, according to one aspect of the present invention, a cabinet in which a refrigerating compartment and a freezing compartment are formed, a door for opening and closing a refrigerating compartment and a freezing compartment of the cabinet, a refrigerant flow channel disposed at a rear portion of the cabinet, In the refrigerator comprising a heat sink for dissipating heat of the refrigerant path pipe, a machine room formed in the lower portion of the cabinet, and a cover for shielding the front lower portion of the cabinet, a plurality of branch pipes attached to the heat sink and directed downward And a cleaning member including a formed first suction pipe, a second suction pipe attached to the heat dissipation plate, and having a plurality of branch pipes facing upward, and a discharge pipe connected to a junction of the first suction pipe and the second suction pipe. do.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 and 3, the refrigerator 10 according to the present invention basically includes a cabinet 11 in which a refrigerator compartment and a freezer compartment are formed, and each refrigerator compartment and freezer compartment of the cabinet 11 has a respective door 12. It is opened and closed by.

In addition, the lower part of the cabinet 11 is formed with a machine room 13 in which a compressor and other components (not shown) are installed.

On the other hand, the rear side of the cabinet 11 is provided with a refrigerant flow passage 14 in a curved form to purify or condense the compressed refrigerant from the compressor installed in the machine room 13 to execute a refrigeration cycle.

In addition, the coolant flow path tube 14 is surrounded by a heat sink 15 to discharge the heat dissipated from the coolant flow path tube 14 to the outside to condense the refrigerant in the coolant flow path tube, thereby performing a refrigerating / freezing cycle. .

On the other hand, the front of the cabinet 11, more specifically, the cover 16 is provided in the lower portion of the door 12 of the refrigerator to close the front surface of the refrigerator, in particular the lower space to make the appearance compact.

In particular, the refrigerator according to the present invention is provided with a cleaning member 20 for cleaning the back of the refrigerator.

In more detail, the cleaning member 20 is formed in a pipe or tubular shape, and the cleaning member 20 includes a first suction pipe 21 and a second suction pipe 22.

The first suction pipe 21 includes a plurality of branch pipes 23 attached between the refrigerant flow channel 14 of the heat sink 15 and extended downward, and the second suction pipe 22 is the heat sink ( And a plurality of branch pipes 24 attached between the refrigerant flow channel pipes 14 of 15 and extending upward.

Each of the suction pipes 21 and 22 is preferably fixed by an attachment method such as spot welding.

In particular, the suction ports 21a, 22a; 23a, 24a are perforated in each of the suction pipes 21, 22 and the branch pipes 23, 24, and the respective suction ports 21a, 22a, 23a, 24a. ) Is preferably opened toward the refrigerant flow passage 14, and each of the intake holes is preferably formed at a predetermined distance along both sides of the respective suction and branch pipes.

The first suction pipe 21 and the second suction pipe 22 are connected to each other in the connection portion 25, the discharge portion 26 is connected to the connection portion 25 in communication.

The discharge pipe 26 extends, for example, from the top of the machine room 13 to the front lower part of the cabinet 11 and is shielded by the cover 16 in the normal state.

Optionally, the end of the discharge pipe 26 is closed by a cap 27 to prevent pests from entering through the discharge pipe 26 or to prevent foreign matter from entering.

According to the cleaning method of the refrigerator according to the present invention, the housewife or the worker removes the cover 16 provided on the front lower surface of the refrigerator in a state where the refrigerator is normally fixedly disposed.

Subsequently, when the discharge pipe 26 is exposed, the cap 27 is pulled out of the discharge pipe 26, and then the suction pipe P of the vacuum cleaner C is inserted into the discharge pipe 26.

When the cleaner is operated in this state, the suction force of the cleaner C is transmitted to the respective suction pipes 21 and 22 and the respective branch pipes 23 and 24 through the connection part 25 through the discharge pipe 26. Accordingly, the dust or foreign matter of the heat sink 25 is sucked and cleaned through the suction ports 21a, 22a, 23a, and 24a of each suction pipe and the branch pipe.

At this time, each of the suction ports 21a, 22a, 23a, and 24a is directed toward the entire refrigerant channel 14, in particular, to quickly and effectively suck in dust and foreign matter present on the refrigerant channel 14 Can be removed.

After the cleaning is completed, the suction pipe P of the cleaner C is removed from the discharge pipe 26, the cap 27 is inserted, and the cleaning operation is completed by mounting the cover 16 in the correct position.

As a result, according to the refrigerator according to the present invention, it is possible to easily clean the rear surface of the refrigerator, in particular, the refrigerant flow channel in a state in which the refrigerator is kept in a normal state, thereby improving convenience and cleaning the refrigerant flow path tube reliably. There is an effect of improving the efficiency.

While preferred embodiments of the present invention have been described above, it will be understood by those skilled in the art that various modifications and changes can be made without departing from the scope of the appended claims.
