The present invention relates to a refrigerator, and more particularly, to a refrigerator capable of smoothing the flow of cold air in the entire refrigerating compartment and preventing the surrounding area of the refrigerator compartment evaporator from being overcooled or frozen.

In general, a refrigerator is a device that can keep various stored foods fresh for a long time by supplying cold air provided through a freezing cycle to a storage compartment and lowering the inside thereof. Recently, an independent cooling refrigerator has been proposed in which an evaporator is installed in a storage compartment divided into a freezer compartment and a refrigerating compartment so as to maintain an optimal state for a food storage form.

Independent cooling refrigerators are provided with a separate cold air supply device at the rear of the freezer compartment and the rear of the freezer compartment. Such a cold air supply unit has an evaporator and a blower fan, and circulates inside the freezer compartment and the refrigerating compartment to inhale the elevated temperature of the cold air into the evaporator. It has a structure of forcibly exchanging heat, and forcibly cooling cold air having a lower temperature due to heat exchange to a freezer compartment and a refrigerating compartment through a blower fan.

In the conventional independent cooling refrigerator, as shown in FIG. 1, when the inside of the storage compartment satisfies a predetermined temperature and the operation of the blower fan 2 is stopped, the cold cool air around the evaporator 4 is introduced into the storage compartment. In order to prevent the inlet 6a of the cold air suction passage 6 is located on both sides of the upper end of the evaporator (4). Accordingly, the cold air circulated in the storage compartment is sucked through the inlet 6a of the cold air suction passage 6 located on both sides of the upper end of the evaporator 4, and the cold air sucked in this way can exchange heat with the evaporator 4. It is guided downward along the cold air suction passage 6 and discharged to the upper portion of the evaporator 4 through the outlet 6b of the cold air suction passage 6.

However, in the refrigerator having the above structure, the inlet 6a and the outlet 6b of the cold air suction passage 6 are located above the evaporator 4, and a box unit such as a vegetable box is installed in the lower region of the storage compartment. There is a problem that the cold air flow is mainly formed only in the upper region of the storage compartment corresponding to the upper side of the evaporator 4, and the cold air flow is not smoothly performed in the lower region. That is, since the cold air does not flow smoothly to the lower region of the storage chamber, the lower region of the storage chamber forms a higher temperature distribution than the upper region.

In particular, when the refrigerator compartment evaporator and the freezer compartment evaporator are connected in series, the temperature of the refrigerator compartment is satisfied, but the freezer compartment should continue to operate when the temperature of the refrigerator compartment is not satisfied. That is, the refrigerator compartment fan is stopped and the freezer compartment fan is driven so that the refrigerant is continuously supplied to the refrigerator compartment evaporator and the freezer compartment evaporator. Therefore, even if the refrigerator compartment temperature is set within the refrigerator compartment evaporator side, since the cold air is continuously generated and the cold air stays, the surrounding area of the refrigerator compartment evaporator is overcooled, so that the food stored in front of the refrigerator compartment evaporator is supercooled or freezes.

Therefore, uneven temperature distribution at the upper and lower sides of the refrigerating compartment and subcooling problems at the front side of the refrigerating compartment evaporator periodically occur during the operation of the refrigerant cycle.

It includes.

The main body 210 has an inner wound in which the outer shell 211 forming the outer appearance and the freezing chamber 214 and the refrigerating chamber 215 for storing the storage container and food at intervals filled with foaming material inside the outer shell 211 are partitioned left and right ( 212). In the lower rear region of the main body 210, a machine room is provided with a compressor 213a for compressing the high-temperature low-pressure gas phase refrigerant into a high-temperature high-pressure gas phase refrigerant, and a condenser 300 for condensing the refrigerant supplied from the compressor 213a with liquid phase refrigerant. 213 is provided. Accordingly, the refrigerant condensed from the condenser 300 is supplied to the freezer compartment evaporator 231 and the refrigerator compartment evaporator 241, and each of the evaporators 231 and 241 absorbs latent heat to cool the surrounding air.

An ice maker 216 is provided inside the freezer compartment 214, and the ice generated by the ice maker 216 can be taken out by the dispenser 220 provided on the front surface of the freezer compartment 219. Therefore, the user can easily be supplied with ice from the outside without opening the freezer door 219.

The freezer compartment cold air supply unit 230 is provided at the rear region of the freezer compartment 214 to supply the cold air generated by the freezer compartment evaporator 231 to the freezer compartment 214 using the freezer compartment fan 232.

In front of the freezer compartment cold air supply unit 230, a freezing chamber duct 235 having a discharge port 236 through which cold air is discharged and a suction port (not shown) through which cold air is sucked is mounted.

A plurality of shelves 217 are provided in the upper region of the refrigerating chamber 215, and an upper vegetable box 218a and a lower vegetable box 218b for storing fruits or vegetables are provided in the lower region. . In the lower rear region of the refrigerating chamber 215, a water tank 220a for the dispenser 220 is provided at a position corresponding to the upper vegetable box 218a.

The refrigerating compartment cold air supply unit 240 is provided at a rear region of the refrigerating compartment 215 to supply the cold air generated by the refrigerating compartment evaporator 241 to the refrigerating compartment 215 using the refrigerating fan 242. In front of the refrigerating chamber cold air supply unit 240, a refrigerating chamber duct 245 is formed to form a cold air flow path between the refrigerating chamber evaporator 241 and the refrigerating chamber 215.

The refrigerator compartment evaporator 241 is mounted to the rear of the upper vegetable box 218a, and is connected to the freezer compartment evaporator 231 in series. Thus, as shown in FIG. 7, the refrigerant supplied from the compressor 213a and the condenser 300 enters the freezer compartment evaporator 231 after passing through the refrigerator compartment evaporator 241, and then returns to the compressor 231a. Form. Here, the refrigerant supplied from the compressor 213a and the condenser 300 may be introduced into the refrigerator compartment evaporator 241 after passing through the freezer compartment evaporator 231 and then returned to the compressor 213a.

The refrigerator compartment duct 245 includes a suction port 248 and a discharge port 246 formed above the refrigerator compartment evaporator 241 so that the internal cold air of the refrigerator compartment 215 can be sucked and discharged into the refrigerator compartment evaporator 241, and the refrigerator compartment 215. A vent 247 is formed through the lower region of the refrigerator compartment evaporator 241 to allow cold air to enter and exit.

A plurality of suction ports 248 of the refrigerating chamber duct are spaced apart from each other at positions corresponding to the upper sides of the refrigerating chamber evaporator 241. Here, the suction port 248 is formed in the refrigerating chamber duct in the longitudinal direction in a predetermined length (see FIG. 1). Thus, the air of the refrigerating chamber 215 may be introduced into the refrigerating chamber evaporator 241 through the suction port 248.

The plurality of discharge ports 246 of the refrigerating chamber 245 are formed on the upper side of the suction port 248 so as to face the shelves 217. Thus, the cold air generated by the refrigerator compartment evaporator 241 may be discharged into the refrigerator compartment 215 through the discharge port 246.

The vent 247 of the refrigerating chamber 245 is formed below the suction port 248. Here, the vent 247 is formed to penetrate in the transverse direction of the refrigerating chamber 245, the total cross-sectional area of the vent 247 is preferably provided smaller than the total cross-sectional area of the suction port 248. At this time, the total cross-sectional area of the vent 247 must be such that the lower side of the refrigerating compartment 215 does not overcool or freeze when the cold air on the refrigerating chamber evaporator 241 flows rapidly into the lower region of the refrigerating compartment 215. . In addition, the vent 247 is preferably provided toward the right side region of the refrigerating chamber 215. Accordingly, the cold air may be supplied to the right region that forms a relatively high temperature distribution under the influence of the outside air, compared to the left region that maintains the low temperature due to the cold air of the freezing chamber 214.

Here, the guide duct 250 is installed along the inner image of the refrigerating compartment 215 to communicate with the vent 247 and the lower region of the refrigerating compartment 215 in front of the vent 247.

One end of the guide duct 250 is coupled to the vent 247 of the refrigerating chamber duct, and the other end 249 is opened toward the lower region of the refrigerating chamber 215. The guide duct 250 is installed to be inclined downward along the rear inner image of the refrigerating chamber 215. At this time, the other end 249 of the guide duct 250 is provided between the lower side of the refrigerator compartment evaporator 241 and the bottom of the refrigerator compartment 215. Therefore, when the operation of the refrigerating compartment 215, that is, the compressor 213a and the refrigerating compartment fan 242 are on, the air in the refrigerating compartment 215 is the other end 249 of the suction port 248 and the guide duct 250. After being sucked to the refrigerator compartment evaporator 241 side and cooled by the refrigerator compartment evaporator 241, it is discharged to the refrigerator compartment 215 through the discharge port 246 formed above the refrigerator compartment evaporator 241 to open the inside of the refrigerator compartment 215. Circulate Therefore, since the cold air discharged to the discharge port 246 is circulated to the middle and lower regions of the refrigerating chamber 215, the flow may be smooth. In addition, when the temperature of the refrigerating compartment 215 is satisfied and the operation of the refrigerating compartment 215 is stopped and the freezing compartment 214 is to be operated continuously, that is, the refrigerating compartment fan 242 is turned off and the freezer compartment fan 232 is turned on. On, the refrigerant is circulated through the refrigerator compartment evaporator 241 to the freezer compartment evaporator 231 for operation of the freezer compartment 214. Here, when there is no vent 247, the cold air generated by the refrigerator compartment evaporator 241 is not discharged to the refrigerator compartment 215 through the discharge port 246 formed above the refrigerator compartment evaporator 241 and continues on the refrigerator compartment evaporator 241 side. It cools and stays in the lower part of the refrigerator compartment evaporator 241. Therefore, the upper vegetable box 218a provided in front of the refrigerator compartment evaporator 241 may have a problem of being supercooled by the staying cold air or freezing of the water tank 220a. Therefore, the vent 247 is required so that the cold air on the refrigerator compartment evaporator 241 side does not stay under the refrigerator compartment evaporator 241, and the guide duct 250 is required to guide the further to the lower region of the refrigerator compartment 215. Do. Therefore, during the predetermined operation step, the cold air on the refrigerator compartment evaporator 241 side is slowly supplied to the lower side of the refrigerator compartment 215 by gravity, thereby preventing the supercooling of the upper vegetable box 218a and the freezing of the water tank 220a. In addition, the temperature of the lower portion of the refrigerating chamber 215 can be lowered appropriately.

Here, the guide duct 250 is preferably provided in the rear region of the lower vegetable box 218b. The machine room 213 is formed in the rear region of the lower vegetable box 218b. Thus, the lower region of the refrigerating chamber 215 heats from the machine room 213 into the refrigerating chamber 215 to form a temperature distribution relatively higher than the upper region of the refrigerating chamber 215. Therefore, the guide duct 250 is provided in the rear region of the lower vegetable box 218b to maintain the proper temperature of the lower vegetable box 218b.

In addition, the lower left area of the refrigerating chamber 215 may maintain a low temperature due to the cold air effect of the freezing chamber 214, but the right area is relatively high temperature due to the influence of outside air compared to the left area. Therefore, the guide duct 250 is preferably provided in the lower right region of the refrigerating chamber 215. Here, the shape of the guide duct 250 may be variously changed within a range capable of guiding the cold air flowing out from the refrigerating chamber duct 245 to the bottom side of the refrigerating chamber 215 along the inner phase 212 of the refrigerating chamber 215. However, the guided cold air is more preferably provided in a shape that can prevent movement of the guided cold air to the left region of the refrigerating chamber 215.

5 and 6, the cold air flow of the refrigerating chamber 215 will be briefly described as follows.

First, when the operation of the refrigerating compartment 215, that is, the compressor 213a and the refrigerating compartment fan 242 are on, as shown in FIG. 5, air in the refrigerating compartment 215 is provided through the inlet 248. The outlet 246 is sucked into the refrigerator compartment evaporator 241 and passed through the other end 249 of the guide duct 250 to the refrigerator compartment evaporator 241 through the vent 247 and cooled by the refrigerator compartment evaporator 241. Discharged through the refrigerating chamber 215 through. Therefore, the cold air discharged from the discharge port 246 may smoothly flow to the middle and lower regions of the refrigerating chamber 215.

In addition, during operation of the compressor 213a, even when the refrigerating compartment 215 is set inside and the refrigerating compartment fan 242 is turned off, when the freezer compartment 214 needs to be operated, the refrigerant is stored in the freezer compartment through the refrigerator compartment evaporator 241. It is circulated to the evaporator 231. For this reason, cold air continues to generate | occur | produce in the refrigerator compartment evaporator 241 although the set temperature inside the refrigerator compartment 215 is satisfied. The generated cold air may be supplied to the lower region of the refrigerating compartment 215 by its own weight through the guide duct 250 which is in communication with the vent 247 and the lower region of the refrigerating compartment 215, as shown in FIG. 6. .

By this configuration, the cold air in the lower part of the refrigerating compartment 215 during the operation of the refrigerating compartment 215 is sucked into the lower side of the refrigerating compartment evaporator 241 through the guide duct 250, and the refrigerating compartment evaporator 241 in the refrigerating compartment 215 stop operation stage. The cold air cooled at the) side slowly flows out into the lower region of the refrigerating compartment 215 by gravity, and thus the cooling performance of the refrigerating compartment 215 may be smoothly improved. In addition, the cold cold air flows out to the lower region of the refrigerating chamber 215 through the guide duct 250 only for a predetermined time, so that the supercooling or the water tank 220a of the upper vegetable box 218a disposed in front of the refrigerating chamber evaporator 241. Freezing can be prevented.

delete

In the above-described embodiment, the air in the refrigerating chamber is sucked through the vent through the other end of the guide duct to the refrigerating chamber evaporator, but if there is no guide duct, it may be directly sucked into the refrigerating chamber evaporator through the vent.

In the above-described embodiment, the guide duct is installed to be inclined along the inner wound at the rear of the refrigerating compartment, but may be installed toward the side from the rear of the refrigerating compartment. Thus, since cold air flows out to the side of the lower vegetable box affected by outside air, it is possible to maintain an appropriate temperature of the lower vegetable box.

As described above, according to the present invention, the inside of the refrigerating chamber may have a smooth flow of cold air, thereby improving cooling performance.

In addition, the cold air cooled by the refrigerating chamber evaporator flows out into the lower compartment of the refrigerating chamber, thereby preventing overcooling or freezing of the peripheral region of the refrigerating chamber evaporator.
