Description

Refrigerator {REFRIGERATOR}

The present invention relates to a refrigerator, and more particularly, to a refrigerator capable of efficiently implementing the fixing of the damper portion of the louver assembly.

In general, in the case of the refrigerator, as shown in FIG. 1, when the refrigerator is operated and is switched to the cooling mode, the refrigerator is heat exchanged with air around the cooling chamber 10 through the evaporator 11 installed in the cooling chamber 10. Refrigerant gas which produced cold air is sent to the compressor 31 provided in the machine room 30, and is compressed.

In addition, the refrigerant changed to a state of high temperature and high pressure through the compressor 31 generates heat of condensation through the condenser (not shown), and then liquefies to remove impurities and moisture while passing through the dryer (not shown). The evaporation is generated while passing through the expansion valve and the evaporator 11 in a state in which the evaporation is carried out.

The liquid refrigerant, which is not vaporized, passes through an accumulator (not shown) at a low temperature and low pressure, and forms a cooling cycle in which a refrigerant cycle in which liquid remains and gas flows back into the compressor 31 is repeated.

The cold air generated while the refrigerant is circulated according to the cooling cycle as described above is supplied to the storage compartment 20 by the blower fan 12 installed in the cooling chamber 10, and then cooled to circulate the inside of the refrigerator to cool the food stored in the refrigerator. After the operation is performed, the air is returned to the cooling chamber 10 along the cold return duct 21.

In this case, a damper portion 101 is provided in the louver assembly 100 that divides the storage chamber 20 and the cooling chamber 30 to adjust the amount of cold air supplied into the refrigerator.

By the way, the damper door (not shown) of the damper portion 101 is mainly fixed through a foam (Expanded Polystyren (EPS)), in order to maintain the shape of the foam is larger than the injection thickness is required.

Therefore, as the volume of the flow path space in which the cold air flows around the damper portion 101 decreases, the size of the portion fixing the damper door of the damper portion 101 is relatively increased, thereby assembling the louver assembly 100. There was a problem of this deterioration.

In addition, the foam has a problem that the shape required for design is not properly manufactured during the product process due to its physical properties, thereby increasing the defective rate and lowering the productivity.

Therefore, the present invention has been made in order to solve the above problems, an object of the present invention is to assemble the damper door of the damper portion of the damper unit, which is installed in the louver assembly to a separate damper receptor made of an injection, and By attaching it to the louver assembly, it is possible to increase the volume with respect to the flow path through which cold air flows, compared with the conventional.

In addition, the flow path switching portion is installed in the flow path below the damper portion to minimize the flow resistance of the cold air.

Another object of the present invention is to install an ion generator at the edge region of the cold air discharge port to improve the convenience of use by consumers by removing odors in the refrigerator and increasing the shelf life of food.

In order to achieve the above object, the refrigerator according to the present invention includes an upper louver and a lower louver; A fan fixing panel assembled to the upper louver to form a chamber, and having an accommodating opening corresponding to a cold air outlet; A damper part accommodated and mounted in the accommodation opening and configured to include a separate damper receiver and a damper door made of an injection molded product; A side opening of which one side of the receiving opening is opened so that the damper receptor is inserted laterally; And a cover for covering the side opening in a state in which a damper door and a damper receptor are inserted into the accommodation opening.

The lower portion of the cover, characterized in that the flow path switching unit having an inclined surface toward the louver assembly to block the portion of the flow path formed in the fan fixing panel to change the direction of the cold air.

An ion generator is installed inside the accommodation opening.

The receiving opening is characterized in that the receiving groove for the ion generator is installed is formed.

The receiving groove is characterized in that the through-hole is formed for the wire to pass through.

According to the refrigerator according to the present invention having the above-described configuration, by assembling the damper door of the damper portion installed in the louver assembly to a separate damper receptor made of an injection molding, and mounting the damper door to the louver assembly, the volume of the flow path of the cold air flows. Compared with the conventional, there is an effect that can be increased.

In addition, it is possible to minimize the flow resistance of the cold air by installing a flow path switching unit in the flow path under the damper unit.

By installing the ion generator in the edge region of the cold air discharge port, it is possible to increase the deodorization and sterilization effect in the refrigerator, as well as to increase the shelf life of the food, thereby improving consumer convenience.

As a perspective view showing the accommodating groove, the same reference numerals will be given to the same components as those of the prior art in the configuration of the present invention.

In the refrigerator according to the present invention, as illustrated in the conventional drawing of FIG. 1, the cold air generated in the evaporator 11 through the storage compartment 20 and the blowing fan 12 in which food is stored is transferred to the storage compartment 20. The cooling chamber 10 to supply is provided and the louver assembly 100 which divides the said storage chamber 20 and the cooling chamber 10 is provided.

The louver assembly 100 has a panel shape constituting a rear portion of the inside of the refrigerator, and includes an upper louver 110 and a lower louver 120 assembled and fixed to each other.

2 and 3, a blower fan 12 is fixed to the upper louver 110, and a fan fixing panel 130 having a flow path 13 through which cold air flows is assembled to form one chamber. The fan fixing panel 130 is provided with a damper unit 140 that is a cold air amount adjusting device so that the cold air generated in the evaporator 11 moves along the flow path 13 and is discharged into the storage chamber 20. have.

The damper part 140 is accommodated and mounted in the groove-shaped receiving opening 150 corresponding to the cold air outlet 111 provided on the louver assembly 100.

The damper unit 140 includes a damper door 141 for adjusting the amount of cold air through an opening and closing amount, and a separate damper receptor 142 including an injection material in which the damper door 141 is accommodated.

Here, the receiving opening 150 is formed with a side opening 151 having one side open so that the damper receptor 142 is inserted laterally together with the damper door 141.

As described above, the damper door 141 and the damper receptor 142 are inserted into the side opening 151 of the accommodation opening 150, thereby covering the open side opening 151 of the accommodation opening 150. 143).

The cover 143 may be coupled to the receiving opening 150 through a fastening member such as a bolt, which is a fastening means.
