Description

Refrigeration ice container cold air supply device

The present invention relates to a refrigerator ice cold supply device of the refrigerator, and more particularly, a refrigerator ice cold supply device of the refrigerator which can adjust the amount of cold air so that the user can quickly freeze the water contained in the ice maker container when a large amount of ice is required It is about.

As is well known in general, when looking at the cooling cycle of the refrigerator, the refrigerant compressed by the compressor and gasified at high temperature and high pressure is liquefied by heat release by heat exchange with external air while passing through the condenser. The liquefied refrigerant passes through a dryer and a capillary tube to form a cold liquid refrigerant at a low temperature and low pressure in a state where impurities and moisture are removed and is sent to an evaporator in a cooler chamber formed at the rear side of the freezer compartment.

The low temperature and low pressure liquefied refrigerant passing through the evaporator is heated in the freezer compartment and the refrigerating compartment and exchanged by the cold and the evaporator returned through the cold air return duct. The light vapor phase refrigerant, which remains at the bottom of the chamber, is sent to the compressor and the circulation of the refrigerant compressed to high temperature and high pressure by the compressor is performed.

The cold cold heat exchanged by the evaporator in the cooler chamber is supplied to the freezing chamber through the cold air discharge port of the freezing chamber by the rotation of the blowing fan.

Hereinafter, with reference to the accompanying drawings a preferred embodiment of the ice-making container cold air supply of the refrigerator according to the present invention.

Figure 2 is a side cross-sectional view and enlarged cross-sectional view of the freezer compartment showing the ice-making container cold air supply of the refrigerator according to the present invention, Figure 3 is a perspective view of the operating state of the main part according to the present invention.

Referring to FIGS. 2 and 3, the rear wall of the freezing chamber 40 forms a rear wall of the freezing chamber 40 and cold air outlets 42 and 44 are formed at upper and middle portions thereof, and cold air is provided at both sides of the lower end. The freezing chamber 48 in which the return opening 46 is formed is installed.

On the lower surface of the cold air discharge port 44 of the middle portion, a semicircular concave groove 50 having an open upper side is formed.

On the other hand, the rotatable rotating shaft 52 is fixedly installed in the concave groove 50, and one side of the outer circumferential surface of the rotating shaft 52 can open and close the cold air outlet 44 along the longitudinal direction thereof. The plate-shaped opening and closing member 54 is formed.

In addition, a snap protrusion 56 is formed at one side of the outer circumferential surface of the rotation shaft 52 to be perpendicular to the opening and closing member 54.

In addition, the front surface of the middle cold air discharge port 44 of the freezing chamber 48 is provided with a shelf 60 having a cold air flow guide 58 therein.

The shelf 60 is placed on the upper surface of the shelf is stored in the freezer compartment 40, the both ends of the shelf 60 in the shelf bead 62 formed on the inside of the freezer compartment 40 as shown in FIG. The placement part 64 is formed so that it may be settled.

The placement unit 64 is simply formed to extend outward from both side ends of the upper surface of the shelf 60, respectively.

In addition, the cold air flow guide 58 is formed to have a rectangular shape extending downward from the bottom surface of the shelf 60, the front and rear surfaces are opened.

In addition, the rear surface of the shelf 60 is formed with a cutout 66 recessed into the interior of the shelf 60 so that the opening and closing member 54 can be rotated.

The cutout 66 is preferably formed to have the same length as the opening and closing member 56.

In addition, an ice container 68 for freezing ice is installed in the cold air flow guide 58 to be pulled in and out.

Referring to the operation of the ice-making container cold air supply of the refrigerator according to the present invention configured as described above are as follows.

The cool air generated in the evaporator 72 of the cooler chamber 70 is supplied to each inside by a blower fan 74 forcibly discharging into the inside of the refrigerator.

At this time, the cold air supplied to the freezing chamber 40 is supplied to the freezing chamber 40 through the cold air outlets 42 and 44 of the upper and middle portions formed in the freezing chamber 48 and is supplied to the ice making container 68 by the cold air. The water received will freeze.

In particular, when the user needs a large amount of ice in a short time, the opening and closing member 54 which is blocking the cold air outlet 44 of the middle part is opened.

That is, when the user pushes the snap protrusion 56 of the pivot shaft 52 fixed to the indentation groove 50 on the lower surface of the cold air discharge port 44 in the middle portion downward, accordingly, the pivot shaft 52 is At the same time, the opening and closing member 54 blocking the cold air outlet 44 in the middle portion is moved downward to open the cold air outlet 44.

At this time, the cold air supplied through the cold air discharge port 44 of the intermediate part is guided to the cold air guide flow path 58 and is discharged and supplied to the front surface of the freezing chamber 40 through the opening in front of the cold air discharge passage 44.

In addition, at this time, the ice making vessel 68 placed on the cold air flow guide 58 is concentrated by the cold air to freeze ice in a short time.

On the contrary, when a lot of ice is not needed in a short time, the user closes the cold air discharge port 44 of the middle part by the opening / closing member 54.

In this way, the opening and closing member 54 is in close contact with the freezing chamber 48 to block the cold air outlet 44 of the middle portion of the freezing chamber 48 in the cut portion 66 of the shelf (60). The amount of cold air supplied to the cold air guide flow path 58 of the shelf 60 can be appropriately adjusted while being rotated within a range of approximately 90 ° positioned in parallel with the shelf 60.

Therefore, the user can easily adjust the amount of cold air supplied to the cold air flow guide 58 while adjusting the opening and closing member 54 as necessary.

As described above, the present invention provides a cold air control means for controlling the cold air supplied to the ice making container in front of the cold air discharge port of the freezing chamber, when the user needs a lot of ice or wants to make ice in a short time. There is an effect that can increase the amount of cold air.
