The present invention relates to a refrigerator having a warmer, and more particularly, to a refrigerator having a warmer using waste heat generated from a compressor and a condenser.

A general refrigerator is a device that keeps food fresh for a period of time by keeping the inside of the refrigerator at a low temperature as the refrigerant performs compression, condensation, expansion, and evaporation.

Hereinafter, a general refrigerator will be described with reference to FIG. 1.

1 is a configuration diagram schematically showing a cooling system of a typical refrigerator.

The main body 10 of the refrigerator includes a freezing compartment 11, a refrigerating compartment 12, and a machine compartment 13.

A freezing chamber 11 is provided at an upper portion of the main body, a refrigerating chamber 12 is provided at a lower portion of the freezing chamber, and a machine chamber 13 is provided at a lower rear side of the refrigerating chamber.

A compressor 14, a condenser 15, a cooling fan 15a, and the like are installed in the machine room 13, and an evaporator 17 is installed in the freezing chamber 11. In addition, an expansion device 16 is installed in the refrigerant pipe between the condenser 15 and the evaporator 17. Accordingly, the refrigerant compressed in the compressor 14 is condensed in the condenser 15 and then sent to the expansion device 16, and the refrigerant expanded in the expansion device passes through the evaporator 17, and then again the compressor 14 Flows into.

At this time, since the high-temperature refrigerant flows through the compressor 14 and the condenser 15, the cooling fan 15a is rotated in the machine room to cool the compressor and the condenser.

As the cooling fan 15a is rotated, outside air flows into the machine room 13, and the outside air thus introduced is cooled after cooling the compressor 14, the condenser 15, and the like. Accordingly, by cooling the compressor and the condenser it is possible to improve the efficiency of the cooling system.

As described above, the process of cooling the compressor and the condenser is a process that must be performed in the refrigerant cycle, but recently, devices using such waste heat are urgently required.

In order to solve the above problems, an object of the present invention is to provide a refrigerator having a warmer using the waste heat generated from the compressor and the condenser.

In order to achieve the above object, the present invention is a main body that is installed in one side of the storage compartment; An evaporator installed inside the storage compartment; A condenser installed inside the warm room and connected by the evaporator and the refrigerant pipe; A damper provided at one side of the warm room to discharge heat in the warm room; In addition, the refrigerator is provided inside the warm room and has a warmer configured to include: a cooling fan: to condense the heat generated by the condenser.

Hereinafter, a first embodiment of a refrigerator having a warmer according to the present invention will be described with reference to FIGS. 2 to 4.

Figure 2 is a schematic view showing a cooling system of a refrigerator having a warmer of the present invention, Figure 3 is a schematic view showing a first embodiment of the warmer of Figure 2, Figure 4 is installed in the warmer of Figure 2 A diagram showing an embodiment of a condenser.

2 and 3, the refrigerator having a warmer is provided with a storage compartment and a warmer compartment 53.

The storage chamber is composed of a freezing chamber 51 and a refrigerating chamber 52. Or, it is also understood that the refrigerator may be provided with only a warm room and a freezer, or a warm room and a refrigerating room.

An evaporator 65 is installed in the freezing compartment 51, a warming chamber 53 is installed at one side of the freezing chamber, and a condenser 62 and a cooling fan 63 are installed in the warming chamber.
Here, the warm room is preferably installed on the upper portion of the freezer for convenience of use and mounting of the refrigerator.
In addition, it is preferable that a compressor 61 for compressing the refrigerant of the refrigerator is also provided inside the warming room.

The compressor 61, the condenser 62, and the evaporator 65 are sequentially connected by a refrigerant pipe, and an expansion device 64 is installed in the refrigerant pipe between the condenser and the evaporator.

It is preferable that the heater H is further installed in such a warm room chamber 53. The heater H may be installed on the bottom surface, side wall surface or top surface of the warm room chamber 53 according to the designer's intention.

The heater (H) applies a smaller capacity than the capacity of the heater used in the conventional warmer. This is because the heater (H) is only required to be raised by a predetermined temperature in a state in which the heater is maintained at a constant temperature by the heat generated by the compressor 61 and the condenser 62.

Of course, if it is possible to maintain the required temperature only by the heat generated from the compressor 61 and the condenser 62, it is also understood that there is no need to install a separate heater.

A discharge damper 67 is installed at a predetermined portion of the wall of the warm room 53 to discharge the heat of the warm room 53 to the outside. In addition, a suction damper 66 is installed to suck the outside air into the warm room. These dampers 66 and 67 are preferably installed at the position where the inflow and outflow of the outside air is best considering the positions of the compressor 61 and the evaporator 65.

In addition, the heat exchange fins 62a forming the upper surface of the condenser 62 are formed in a plate shape so as to place a heating object as shown in FIG. 4.

The condenser 62 has a structure in which a plurality of heat exchange fins are stacked to be parallel to the bottom surface, and a separate heat exchange fin 62a for placing a heating object on the top surface thereof is installed.

Of course, the heat exchange fin of the condenser 62 is erected in the vertical direction, it can be understood that a separate plate heat exchange fin can be installed to form an upper surface of the heat exchange fin.

Accordingly, the heat exchange fins 62a may be used as a shelf on which a drink container or a beverage container may be placed, and the drink container may be heated more quickly.

The operation of the first embodiment of the refrigerator having a warmer configured as described above will be described.

When the storage compartment is out of the temperature range preset by the controller, the refrigerator having the warmer performs a cooling cycle to maintain the freezing compartment 51 and the refrigerating compartment 52 within the preset temperature range.

At this time, the compressor 61 and the condenser 62 are heated by a high temperature refrigerant, and the inside of the warm room chamber 53 is also heated by heat.

In addition, the suction and discharge dampers 66 and 67 are both opened and the cooling fan 63 is operated.

The outside air introduced into the warm room chamber 53 by the action of the cooling fan 63 is discharged to the outside after heat exchange with the compressor 61 and the condenser 62. At this time, even if the heat is discharged to the outside, the warm room 53 is maintained at a somewhat high temperature.

Next, when the temperature of the storage compartment is maintained within the temperature range preset by the controller, the cooling cycle of the refrigerator having the warmer is stopped.

At this time, the suction and discharge dampers 66 and 67 are both closed and the cooling fan 63 is operated to convection the air in the warm room chamber 53.

This convection air is heated by the compressor 61 and the condenser 62 heated by the high temperature refrigerant to raise the temperature in the warm room 53 further.

In such a warmer, it is possible to heat the drink using the waste heat generated from the compressor and the condenser.

A second embodiment of a refrigerator having a warmer according to the present invention will be described with reference to FIG. 5.

Figure 5 is a schematic diagram showing a second embodiment of the warmer.

The warmer is provided with a compressor 61, a cooling fan 63, and a condenser 72.

The condenser 72 is installed to expose a predetermined portion on the indoor side and the outdoor side of the warmer. At this time, the exposure ratio of the indoor side and the outdoor side portions 72a and 72b should be determined in consideration of the capacity of the warm room 53.

The refrigerant pipe is branched so as to independently supply the refrigerant to the indoor portion 72a and the outdoor portion 72b of the condenser. In addition, at the branched portion of the refrigerant pipe, a switching valve 73 is provided to selectively switch the refrigerant to the indoor portion 72a and the outdoor portion 72b of the condenser. As the switching valve 73, a tree way valve is applied.

In addition, it is preferable to install a separate cooling fan 74 near the outdoor portion 72b of the condenser. This cooling fan 74 serves to cool the outdoor portion 72b of the condenser.

A suction damper 66 and a discharge damper 67 are provided at a predetermined portion of the wall of the warm room chamber 53 so as to suck the outside air to the outside.

In addition, it is preferable that a heater H is further installed inside the warm room 53. Such a heater may be installed on the bottom surface, side wall surface or top surface of the warm room according to the intention of the designer. In addition, the heater applies a smaller capacity than the capacity of the heater used in the conventional warmer.

Since the heater is the same as described above, a description thereof will be omitted.

The operation of the second embodiment of the refrigerator having a warmer configured as described above will be described.

When the temperature in the warm room chamber 53 is within a temperature range preset by the controller, the switching valve 73 is switched so that the refrigerant flows only into the outdoor portion 72b of the condenser. At this time, by operating the cooling fan 74 installed near the outdoor side portion 72b of the condenser, the refrigerant flowing in the outdoor side portion 72b is condensed.

The temperature in the warm room is kept constant by closing or slightly opening the suction and discharge dampers 66 and 67.

Next, when the temperature in the warm room 53 is outside the temperature range preset by the controller, the switching valve 73 is switched so that the refrigerant flows into the indoor and outdoor portions 72a and 72b of the condenser. .

At this time, by operating the cooling fan 74 installed near the outdoor side portion, the outdoor side portion 72b of the condenser is cooled.

At the same time, the suction and discharge dampers 66 and 67 are all closed and the indoor cooling fan 63 is operated to raise the inside of the warm room 53 to a predetermined temperature.

In addition, the heater (H) is operated to maintain the temperature of the warm room chamber 53 within a preset temperature range.

When the temperature of the warm room is maintained within the preset temperature range by this action, the switching valve 73 is switched so that the refrigerant flows only into the outdoor portion 72b of the condenser.

A third embodiment of a warm room according to the present invention will be described with reference to FIG. 6.

Figure 6 is a schematic diagram showing a third embodiment of the warmer.

In the warm room, partition plates 81 are provided to partition the inside of the warm room into two spaces 53a and 53b.

A compressor 61, a condenser 62, and a cooling fan 63 are installed in any one of the spaces 53a and 53b, to discharge the heat of any one of the spaces to the space or the outside. A switching damper 88 is provided. In addition, it is preferable that the heater H is further installed in the other space part.

For example, as illustrated in FIG. 6, a partition plate 81 is provided to partition the inside of the warm room 53 into front and rear space parts 53a and 53b, and a compressor 61 is provided in the rear space part 53b. ), A condenser 62 and a cooling fan 63 are installed, and a heater H is installed in the front space part 53a.

At this time, an outside air suction port 82 and a hot air discharge port 83 are formed on a wall surface of the rear space part 53b, and the hot air intake port 84 is configured to send heat to the front space part 53a in the partition plate 81. Is formed, and a switching damper 88 is installed to selectively open and close the hot air discharge port 83 and the hot air suction port 84.

Here, it is more preferable to provide a hot air inlet 84 near the hot air discharge port 83. This is for selectively opening and closing the hot air discharge port 83 and the hot air suction port 84 with one switching damper 88.

Of course, it is also understood that a damper may be provided at each of the hot air discharge port and the hot air suction port.

At this time, the hot air discharge port 83 is preferably formed in a position where the user is not exposed to heat.

In addition, the outside space inlet port 82 and the hot air discharge port 83 are formed to face each other in the rear space portion 53b, and the compressor 61 and the condenser 62 are installed on the cold air discharge side of the cooling fan 63. It is preferable.

This is to allow the compressor and the condenser to be cooled simultaneously as one cooling fan 63.

Next, the case where the said warming room is divided into both sides is demonstrated. Since the structure of such a warm room is almost similar to FIG. 6, illustration thereof will be omitted.

A partition plate is installed to partition the interior of the warm room into both space parts, a compressor, a condenser and a cooling fan are installed in one space part of the warm room, and a heater is installed in the other space part.

At this time, an outside air inlet and a hot air outlet are formed on a wall of the one side space portion, and a hot air inlet is formed on the partition plate to send heat to the other space, and a damper is installed to selectively open and close the hot air outlet and the hot air intake port. .

In this case, it is preferable that a hot air inlet is formed near the hot air outlet, and the hot air outlet is formed at a position where the user is not directly exposed to hot air.

Of course, it is also possible to install a damper in each of the hot air outlet and hot air inlet.

The operation of the third embodiment of the refrigerator having a warm room configured as described above will be described.

When the temperature in the warm room 53 is within a temperature range preset by the controller, the cooling fan 63 is rotated to cool the compressor 61 and the condenser 62.

At the same time, the switching damper 88 is rotated to open the hot air discharge port 83 and close the hot air suction port 84 formed in the partition plate 81.

Accordingly, the heat of the rear space portion 53b is discharged to the outside by the action of the cooling fan 63.

Next, when the temperature in the warm room chamber 53 is outside the temperature range set by the controller, the switching damper 88 is rotated to close the hot air discharge port 83 and open the hot air suction port 84. .

Accordingly, the heat of the rear space portion 53b is introduced into the front space portion 53a through the hot air suction port 84 of the partition plate 81, and the heat is increased by increasing the temperature of the front space portion. Warm up the received heating object.

At this time, when the temperature of the front space portion 53a is less than or equal to a preset temperature range, the heater H is operated to raise the temperature of the front space portion to a predetermined temperature.

As described above, the present invention makes it possible to utilize the waste heat generated in the compressor and the condenser in the warmer.
