Is maintained. The first storage chamber 110 and the second storage chamber 130 are partitioned by the partition wall 170.

In addition, the first storage compartment 110 and the second storage compartment 130 may be utilized for various purposes such as a refrigerating compartment, a refrigerating compartment, and a quick freezing compartment by adjusting the room temperature. For convenience of description, the first storage compartment 110 will be described based on the fact that the refrigerator compartment and the second storage compartment 130 are used as the freezing compartment.

In addition, in the present embodiment, it has been described that two storage compartments are provided in the main body 100 of the refrigerator 10, but the present invention is not limited thereto. It can also be used as a quick freezer.

The machine room 150 is provided in the main body 100, and some of the components constituting the refrigeration cycle of the refrigerator 10, for example, a compressor, a condenser, and a fan motor assembly (not shown) are installed. The machine room 150 communicates with the cold air generation chamber 300 to be described later, and the refrigerant passing through the compressor and the condenser is transferred to the evaporator 310.

The cold air generating chamber 300 is provided at the rear of the second storage chamber 130, and is partitioned from the second storage chamber 130 by the barrier 132, and an evaporator 310 for generating cold air is installed therein.

The evaporator 310 receives coolant that is sequentially passed through the compressor and the condenser of the machine room 150 to generate cold air through heat exchange, and the cold air generated from the evaporator 310 may be described later in the first cold air supply duct 400. And the first storage chamber 110 and the second storage chamber 130 through the second cold air supply duct 500.

The first cold air supply duct 400 extends upward from the lower end of the rear of the first storage chamber 110 and is partitioned from the first storage chamber 110 through the barrier 112.

In addition, the first cold air supply duct 400 is in communication with the cold air generating chamber 300 through the cold air inlet 400a provided at the bottom, and through the plurality of cold air outlets 400b formed at predetermined intervals in the barrier 112. In communication with the first storage compartment 110.

Accordingly, the cold air generated in the cold air generating chamber 300 flows into the first cold air supply duct 400 and then into the first storage chamber 110 through the plurality of cold air discharge ports 400b formed in the barrier 112. Can be supplied.

The second cold air supply duct 500 is provided between the front surface of the cold air generating chamber 300, that is, between the cold air generating chamber 300 and the barrier 132, and extends downward from the upper end of the rear side of the second storage chamber 130. It is formed.

In addition, the second cold air supply duct 500 communicates with the cold air generating chamber 300 through the cold air inlet 500a provided on the rear surface, and through the plurality of cold air discharge ports 500b formed at predetermined intervals in the barrier 132. In communication with the second storage chamber 130.

Accordingly, the cold air generated in the cold air generating chamber 300 flows into the second cold air supply duct 500 and then into the second storage chamber 130 through the plurality of cold air discharge ports 500b formed in the barrier 132. Can be supplied.

Meanwhile, as described above, since the first cold air supply duct 400 and the second cold air supply duct 500 are configured to communicate with the cold air generation chamber 300, the cold air generated in the cold air generation chamber 300 may be the first. Branched into the cold air supply duct 400 and the second cold air supply duct 500 is bound to be supplied at the same time.

Accordingly, even when only one of the indoor temperatures of the first storage chamber 110 and the second storage chamber 130 is higher than the set temperature, cold air is supplied to both of the first storage chamber 110 and the second storage chamber 130. Power is wasted.

In addition, in order to supply cold air to both the first storage chamber 110 and the second storage chamber 130, the capacity of the compressor (not shown) constituting the refrigeration cycle of the refrigerator 10 must be increased, and thus the cost of the compressor increases. do.

Therefore, in order to solve this problem, in the first embodiment of the present invention, the first damper 410, the first blowing fan 430, and the second blowing fan 330 include the first storage chamber 110 or the second storage chamber ( 130 may optionally be supplied with cold air.

The first damper 410 is installed in the first cold air supply duct 400 to open and close the first cold air supply duct 400, and selectively block the flow of cold air supplied to the first storage chamber 110.

In addition, the first damper 410 is preferably installed in the cold air inlet 400a where the first cold air supply duct 400 and the cold air generation chamber 300 communicate with each other, but is not limited thereto.

The first blowing fan 430 may be installed in the first cold air supply duct 400, and guide the cold air generated in the cold air generation chamber 300 to the first cold air supply duct 400. More specifically, the first blowing fan 430 is disposed to be adjacent to the first damper 410 on the upper side of the first damper 410, a turbo fan or an axial fan may be used, but is not limited thereto.

The second blowing fan 330 may be installed in the cold air generating chamber 300, and guide the cold air generated in the cold air generating chamber 300 to the second cold air supply duct 500. More specifically, the second blowing fan 330 is disposed in the upper center of the cold air generating chamber 300 to be disposed above the evaporator 310, but a turbo fan or an axial fan may be used, but is not limited thereto.

Hereinafter, cold air is selectively supplied to the first cold air supply duct 400 or the second cold air supply duct 500 by using the first damper 410, the first blowing fan 430, and the second blowing fan 330. How to do this will be described.

First, as illustrated in FIG. 2A, when the first damper 410 opens the first cold air supply duct 400, the first blowing fan 430 is operated, and the second blowing fan 330 is not operated. Is stopped.

Accordingly, the cold air generated in the cold air generating chamber 300 is forcibly circulated by the first blower fan 430 and guided to the first cold air supply duct 400, and then the first storage chamber ( 110).

In this case, since the second cold air supply duct 500 is not provided with a structure for blocking cold air, cold air may flow into the second cold air supply duct 500, but cold air may be removed by the first blower fan 430. As forcedly circulated to the first cold air supply duct 400, substantially no cold air flows to the second cold air supply duct 500. As a result, the cold air generated in the cold air generating chamber 300 is intensively supplied to the first cold air supply duct 400.

Next, as shown in FIG. 2B, when the first damper 410 closes the first cold air supply duct 400, the operation of the first blowing fan 430 is stopped and the second blowing fan 330 is It works.

Accordingly, the cold air generated in the cold air generating chamber 300 is forcibly circulated by the second blower fan 330 and guided to the second cold air supply duct 500, and then the second storage chamber ( 130). As a result, the cold air generated in the cold air generating chamber 300 is intensively supplied to the second storage chamber 130.

As such, by providing the first damper 410, the first blowing fan 430, and the second blowing fan 330, the cold air generated in the cold air generating chamber 300 is provided in the first storage chamber 110 or the second storage chamber. It is possible to supply to 130 independently. As a result, the capacity of the compressor constituting the refrigeration cycle can be reduced compared to the case where cold air is simultaneously supplied to the first storage chamber 110 and the second storage chamber 130, thereby reducing costs.

In addition, after opening the first cold air supply duct 400 through the first damper 410 as well as selectively supplying the cold air independently of the first storage compartment 110 or the second storage compartment 130, It is also possible to supply cold air to the first storage compartment 110 and the second storage compartment 130 by operating both the first blower fan 430 and the second blower fan 330.

Here, the order of supplying cold air to the first storage compartment 110 and the second storage compartment 130 is not particularly limited, but before the first storage compartment 130 used as a freezer compartment in the first storage compartment 110 used as a refrigerating compartment, It is preferable to supply.

This is because the set temperature of the refrigerating compartment is higher than the set temperature of the freezer compartment, and therefore, when cold air is selectively supplied to the refrigerating compartment, the evaporator temperature of the evaporator 310 may be relatively higher than when cold air is selectively supplied to the freezer compartment. .

Therefore, after supplying cold air to the first storage compartment 110, which is a refrigerating chamber independently, and then supplying cold air to the second storage compartment 130, which is a freezing chamber, power consumption can be minimized.

Meanwhile, in order to return the cold air selectively supplied to the first storage chamber 110 or the second storage chamber 130 to the cold air generation chamber 300 as described above, the first cold air return duct 600 and the second cold air recovery are performed. Duct 700 is provided.

The first cold return duct 600 is provided inside the rear wall of the main body 100, but is not particularly limited, but two first cold return ducts 600 are provided in this embodiment. In addition, the first cold air return duct 600 communicates with the first storage chamber 110 through cold air inlets 600a formed at both ends of the lower portion of the barrier 112 of the first storage chamber 110, and the cold air generating chamber 300. It is communicated with the cold air generating chamber 300 through the two cold air discharge port (600b) formed spaced apart from each other at the lower portion of the back.

Accordingly, the cold air introduced into the first storage chamber 110 through the first cold air supply duct 400 may flow into the first cold air return duct 600 to be returned to the cold air generating chamber 300.

The second cold air return duct 700 extends from the cold air intake port 700a formed in the lower portion of the second storage chamber 130, and is formed through the cold air discharge port 700b formed in the lower surface of the front surface of the cold air generation chamber 300. In communication with the cold air generating chamber (300).

Accordingly, the cold air introduced into the second storage chamber 130 through the second cold air supply duct 500 may be introduced into the second cold air return duct 700 and returned to the cold air generating chamber 300.

3 is a side cross-sectional view of a refrigerator according to a second embodiment of the present invention. Hereinafter, a second embodiment of the present invention will be described with reference to FIG. 3.

In the case of the second embodiment of the present invention, the basic configuration is the same as the first embodiment of the present invention, except for the second damp air supply duct 500 and the second cold air return duct 700 in addition to the first damper 410. The difference is that additional dampers are provided for opening and closing each.

The second damper 510 is installed in the second cold air supply duct 500 to open and close the second cold air supply duct 500, and selectively block the flow of cold air supplied to the second storage compartment 130. In addition, the second damper 510 is preferably installed at the cold air inlet 500a in which the second cold air supply duct 500 and the cold air generation chamber 300 communicate with each other, but are not limited thereto.

The third damper 710 is installed in the second cold air return duct 700 to open and close the second cold air return duct 700, and selectively block the flow of cold air returned to the cold air generation chamber 300. In addition, the third damper 710 may be installed at the cold air inlet 700a in which the second cold air return duct 700 and the second storage chamber 130 communicate with each other, but are not limited thereto.

By installing the second damper 510 and the third damper 710, when cold air is selectively supplied to the first storage compartment 110, a part of the cold air may be more effectively blocked from entering the second storage compartment 130. have.

Hereinafter, the first cold air supply duct 400 or the second cold air supply duct (using the first to third dampers 410, 510, 710, the first blowing fan 430, and the second blowing fan 330). A method of selectively opening and closing 500) will be described.

First, when the first damper 410 opens the first cold air supply duct 400, the second damper 510 and the third damper 710 may return the second cold air supply duct 500 and the second cold air return. Each of the ducts 700 is closed, and the first blowing fan 430 is operated and the second blowing fan 330 is stopped.

That is, to selectively supply cold air to the first storage compartment 110, the second air conditioner 510 and the third damper 710 are used to completely cut off between the cold air generation chamber 300 and the second storage compartment 130. By operating the first blower fan 430 in the state, it is possible to forcibly circulate all the cold air generated in the cold air generating chamber 300 to the first storage chamber (110).

Next, when the first damper 410 closes the first cold air supply duct 400, the second damper 510 and the third damper 710 may be the second cold air supply duct 500 and the second cold air. Each of the return ducts 700 is opened, and the first blower fan 430 is stopped and the second blower fan 330 is operated.

That is, to selectively supply cold air to the second storage chamber 130, the second blower fan is completely blocked between the cold air generating chamber 300 and the first storage chamber 110 using the first damper 410. By operating the 330, all of the cold air generated in the cold air generation chamber 300 may be forcedly circulated to the second storage chamber 130.

In the second embodiment of the present invention, the order in which cold air is supplied to the first storage chamber 110 and the second storage chamber 130 is not particularly limited. However, as in the first embodiment of the present invention, in order to reduce power consumption, cold air is first independently supplied to the first storage chamber 110 used as the refrigerating chamber, and then independent of the cold air to the second storage chamber 130 used as the freezing chamber. It is preferable to supply.

4 is a view illustrating a state in which a first cold return duct is provided in the refrigerator according to the third embodiment of the present invention, and FIGS. 5A and 5B illustrate a cold air circulation structure of the refrigerator according to the third embodiment of the present invention. A diagram for explaining. Hereinafter, a third embodiment of the present invention will be described with reference to FIGS. 4, 5A and 5B.

The third embodiment of the present invention has the same basic configuration as the first and second embodiments of the present invention. However, the cold air discharge port 1600b in which the first cold air return duct 1600 and the cold air generation chamber 1300 communicate with each other, and the cold air discharge port 1600b in which the second cold air return duct 1700 and the cold air generation chamber 1300 communicate with each other. There is a difference between the position and the configuration of the blocking film 1312 in the evaporator 1310.

The first cold air return duct 1600 communicates with one side of the cold air generation chamber 1300, and the cold air returned from the first storage chamber 1110 to the cold air generation chamber 1300 passes through one side of the evaporator 1310, and then again. It may be supplied to the storage compartment 1110.

More specifically, the first cold air return duct 1600 is in communication with the first storage compartment 1110 through two cold air intake holes 1600a provided at the lower portion of the barrier 1112 of the first storage compartment 1110. It extends along the inside of the rear wall. As shown in the figure, the first cold air return duct 1600 extends to two galles along two cold air inlets 1600a and is combined into one flow path.

Here, the first cold air return duct 1600 combined into one flow path is in communication with the cold air generation chamber 1300 through a cold air discharge port 1600b which is formed to be biased toward one side of the lower rear surface of the cold air generation chamber 1300.

Also, in the case of the cold air inlet 1400a of the first cold air supply duct 1400, the cold air generation chamber 1300 corresponds to the position at which the cold air outlet 1600b of the first cold air supply duct 1400 is formed. It may be formed to be biased toward one side of the top surface.

As described above, the cold air discharge port 1600b of the first cold air return duct 1600 and the cold air inlet 1400a of the first cold air supply duct 1400 are biased to one side of the cold air generation chamber 1300 to circulate the cold air. The structure will be described later.

The second cold air return duct 1700 communicates with the other side of the cold air generating chamber 1300, and the cold air returned from the second storage chamber 1130 to the cold air generating chamber 1300 passes through the other side of the evaporator 1310, and then returns to the second side. It may be supplied to the storage compartment 1130.

More specifically, the second cold air return duct 1700 is in communication with the cold air generating chamber 1300 through the cold air discharge port 1700b formed in the lower portion of the front surface of the cold air generating chamber 1300. Here, the cold air discharge port 1700b of the second cold air return duct 1700 is lower than the front surface of the cold air generation chamber 1300 so as not to face the cold air discharge port 1700b of the first cold air return duct 1600. It is formed to be biased toward the other side of.

In addition, in the case of the cold air inlet 1500a of the second cold air supply duct 1500, the front surface of the cold air generation chamber 1300 corresponds to the cold air outlet 1700b of the second cold air return duct 1700, as shown in the drawing. It may be formed biased to the other side of.

As described above, in the third embodiment of the present invention, the cold air inlet 1400a of the first cold air supply duct 1400 for communicating the cold air generating chamber 1300 and the first storage chamber 1110, and the first cold air return duct ( The cold air discharge port 1600b of the 1600 is biased toward one side of the cold air generation chamber 1300.

Correspondingly, the cold air inlet 1500a of the second cold air supply duct 1500 for communicating the cold air generating chamber 1300 and the second storage chamber 1130, and the cold air outlet 1700b of the second cold air return duct 1700. ) Is biased toward the other side of the cold air generating chamber 1300.

The cold air circulation structure in the third embodiment of the present invention described above is as follows.

First, to selectively supply cold air to the first storage chamber 1110, the first cold air supply duct 1400 is opened through the first damper 1410, and the first blowing fan 1430 is operated. 2 The operation of the blower fan 1330 is stopped to circulate cold air to the first storage chamber 1110.

As illustrated in FIG. 5A, the cool air supplied to the first storage chamber 1110 is circulated through the first storage chamber 1110 and returned to the cold air generation chamber 1300 through the first cold return duct 1600.

Here, the cold air discharge port 1600b of the first cold air return duct 1600 and the cold air inlet 1400a of the first cold air supply duct 1400 are formed to be biased toward one side of the cold air generation chamber 1300, and thus, the first storage chamber ( The cold air returned from the 1110 is heat-exchanged while passing through one side of the evaporator 1310 and then supplied to the first storage chamber 1110 again.

Next, in the case of selectively supplying cold air to the second storage chamber 1130, the first cold air supply duct 1400 is closed through the first damper 1410 and the operation of the first blower fan 1430 is stopped. The second blower fan 1330 is operated to circulate cold air to the second storage compartment 1130.

The cold air supplied to the second storage chamber 1130 is circulated through the second storage chamber 1130 and returned to the cold air generating chamber 1300 through the second cold air return duct 1700 as illustrated in FIG. 5B.

Here, the cold air outlet 1700b of the second cold air return duct 1700 and the cold air inlet 1500a of the second cold air supply duct 1500 are formed to be biased toward the other side of the cold air generation chamber 1300, and thus, the second storage chamber ( The cold air returned from the 1130 is heat-exchanged while passing through the other side of the evaporator 1310 and then supplied to the second mortgage chamber 1130 again.

As described above, in the third embodiment of the present invention, the cold air supplied to or returned from the first storage chamber 1110 passes through only one side of the evaporator 1310 and is supplied to or returned from the second storage chamber 1130. Passes only the other side of the evaporator 1310.

That is, as shown in the drawing, in order to circulate cold air to the first storage chamber 1110, the first cold air passage 1800 passing through only one side of the evaporator 1310, and independently of this, circulates cold air to the second storage chamber 1130. In order to do so, the first cold air passage 1900 passing only the other side of the evaporator 1310 is provided.

By providing the first cold air passage 1110 and the second cold air passage 1130 independent of each other, it is possible to concentrate the cold air in a part of the evaporator 1310 to increase the efficiency of the evaporator 1310, a part of the evaporator 1310 In this case, since the amount of refrigerant circulating can be reduced, work of a compressor (not shown) can be reduced, thereby reducing power consumption.

On the other hand, in order to more clearly partition the first cold air flow path 1110 and the second cold air flow path 1130, the third embodiment of the present invention may further include a configuration of the blocking film 1312.

The blocking film 1312 is installed in the evaporator 1310 and prevents the cold returned from the first storage chamber 1110 and the cold air returned from the second storage chamber 1130 from being mixed with each other. That is, the cold air recovered from the first storage chamber 1110 is concentrated through the blocking film 1312 to the first refrigerant flow path 1800, and the cold air recovered from the second storage chamber 1130 is concentrated into the second refrigerant flow path 1900. You can.

Meanwhile, since the first storage chamber 1110 is used as a refrigerating chamber and the second storage chamber 1130 is used as a freezing chamber, the load of the second storage chamber 1130 is relatively greater. Accordingly, the regions corresponding to the second refrigerant passage 1900 are larger than the regions corresponding to the first refrigerant passage 1800 such that the cold air inlets 1400a and 1500a, the cold air outlets 1600b and 1700b, and the blocking film 1312 are formed. The position can be adjusted.

Meanwhile, in addition to the first storage chamber 1110 and the second storage chamber 1130, a third storage chamber (not shown) used as a quick freezing chamber may be further provided. In this case, by providing the third blowing fan 1350 on one side of the second blowing fan 1330 for guiding the cold air to the third storage chamber, the second blowing fan 1330 and the third sending fan 1350 together. In operation, cold air may be simultaneously supplied to the second storage chamber 1130 and the third storage chamber.
