Description

refrigerator

FIELD OF THE INVENTION The present disclosure relates to a refrigerator.

BACKGROUND OF THE INVENTION Generally, in a refrigerator, cold air is generated in a cooling chamber on the back surface of a refrigerator main body, and the cold air is circulated into a refrigerating compartment, a freezing compartment, a vegetable compartment, or the like by a blower to cool the food in each compartment. In such a refrigerator, there is a refrigerator in which, in addition to the refrigerating compartment flap that adjusts the amount of cold air circulation toward the refrigerating compartment, a vegetable compartment baffle that controls the amount of cold air circulation toward the vegetable compartment is provided, and is capable of being efficient. The vegetable compartment is cooled (for example, refer to Patent Document 1).

FIG. 33 shows a conventional refrigerator described in Patent Document 1. As shown in FIG. 33, in the refrigerator 100, the cooling chamber 101 is provided on the back surface of the freezing compartment 102, and cold air is generated in the cooling chamber 101. The cold air is supplied to the refrigerating chamber 103 through the cold air passage portion 105 and the refrigerating chamber duct 106. The cold air passage portion 105 is provided in a partition 104 that partitions the refrigerating chamber 103 from the freezing chamber 102, and the refrigerating chamber duct 106 is connected. In the cold air passage portion 105. Further, the cold air is supplied to the vegetable compartment 108 through the vegetable compartment duct 107 in the refrigerator 100, and the vegetable compartment duct 107 is a duct that branches from the cold air passage section 105. A refrigerating compartment shutter 109 is incorporated in a portion of the refrigerating compartment duct 106 that faces the cold air passage portion 105. The vegetable compartment shutter 110 is incorporated in a branch portion of the cold air passage portion 105 formed in the partition 104 toward the vegetable compartment duct 107. With this configuration, it is possible to control the amount of supply of cold air to each of the rooms of the refrigerating compartment 103 and the vegetable compartment 108. Furthermore, the refrigerator shown in FIG. 33 has a cooling fan 111 and a cooler 112.

According to the refrigerator described in Patent Document 1, the supply of cold air to the vegetable compartment 108 can be controlled independently of the supply of cold air to the refrigerating compartment 103 (see FIG. 33). Accordingly, there is an advantage that the inside of the vegetable compartment 108 is not excessively cooled or dried, and the inside of the vegetable compartment 108 can be effectively cooled.

However, in the configuration of the conventional refrigerator described above, the cold air supplied from the cooling chamber 101 to the vegetable compartment 108 is blown up to the divergent portion of the cold air passage portion 105 of the partition 104 above the cooling chamber 101, and then It is supplied to the vegetable compartment 108 below the cooling chamber 101. Therefore, the length of the vegetable compartment pipe 107 becomes long, and the passage resistance becomes large. In such a conventional refrigerator, there is a problem in that when the vegetable compartment baffle 110 is opened, the total cold air circulation amount including the cold air circulation to the refrigerating compartment when the vegetable compartment 108 is cooled is lowered, and the cooling capacity is lowered. Question.

Further, in general, the refrigerator generates cold air in a cooling chamber on the back surface of the refrigerator main body, and circulates the cold air into a refrigerating compartment, a freezing compartment, a vegetable compartment, or the like by a blower to cool the food in each compartment. In such a refrigerator, there is a refrigerator in which, in addition to the refrigerating compartment flap that adjusts the amount of cold air circulation to the refrigerating compartment, a freezer compartment flapper that controls the amount of cold air circulation toward the freezing compartment is provided, and is capable of being efficient. The freezer compartment is cooled (for example, refer to Patent Document 2).

FIG. 34 is a longitudinal cross-sectional view of a conventional refrigerator described in Patent Document 2. As shown in FIG. 34, in the refrigerator 200, the freezing compartment 202 is provided below the refrigerating compartment 201, and the cooling compartment 203 is provided in the back of the freezing compartment 202. The refrigerator 200 is configured to circulate cold air to the refrigerating compartment 201 and the freezing compartment 202 by the cooling fan 205, which is generated by the cooler 204 provided in the cooling chamber 203. A freezer compartment flapper 207 is provided in the cold air outlet 206 of the cold air toward the freezer compartment 202. The refrigerator 200 is configured to be capable of controlling the amount of cold air supplied from the cooling chamber 203 to the freezing compartment 202 by the freezing compartment shutter 207.

According to the conventional refrigerator 200 described in Patent Document 2, since the amount of cold air supplied to the freezer compartment 202 can be controlled, there is an advantage that the frozen food can be efficiently stored frozen.

However, when the conventional refrigerator 200 performs the defrosting operation in the cooler 204, the high-humidity warm air after defrosting rises through the cooling chamber 203 through the draft to reach the cold air outlet 206, and the warm The chilled air will come into contact with the freezer compartment baffle 207 to condense. There is a concern that the condensed water droplets may freeze when the cooling operation after the defrosting operation is completed again, causing a problem that the operation of the baffle is poor.

Therefore, in the conventional refrigerator 200, in order to prevent icing, it is necessary to provide a heater for preventing icing in the freezer compartment shutter 207, which complicates the configuration and increases the cost. Question.

Further, in general, the refrigerator generates cold air in a cooling chamber provided on the back side of the refrigerator main body, and circulates the cold air into the refrigerating chamber by a cooling fan to cool the food in the refrigerating chamber. In such a refrigerator, the amount of cold air supplied to the refrigerating compartment is controlled by a baffle. The baffle is attached to the lower portion of the refrigerating compartment duct provided on the back surface of the refrigerating compartment (for example, refer to Patent Document 3).

FIG. 35 shows a configuration of a refrigerator compartment duct of a conventional refrigerator described in Patent Document 3. In Fig. 35, the refrigerating compartment duct 300 is composed of a duct member 301 which is made of a heat insulating material such as foamed styrene, and a duct cover 302 which is made of resin and which is covered. The surface of the pipe member 301. A refrigerator compartment shutter 304 is incorporated in a lower portion of the passage portion 303 formed on the duct member 301. The refrigerating compartment shutter 304 is covered by the flap cover 305 and is attached to the rear wall of the refrigerating compartment through the sealing member 306.

According to the refrigerating compartment duct 300 of the conventional refrigerator described in the patent document 3, the cold air permeation chamber 306 may leak into the passage portion 303 and condense. Therefore, recently, the refrigerating compartment duct is configured such that, on the back side of the duct member 301, that is, on the back wall side of the refrigerating compartment, the heat insulating sheet is adhered to cover the passage portion 303, and even if the cold air leaks from the refrigerating compartment, the leaked cold air does not enter the passage. In section 303.

However, in the refrigerating compartment duct thus constructed, the cold air leaking from the refrigerating compartment is condensed around the back side of the heat insulating sheet covering the passage portion 303. There is a problem in that the condensation is dripped depending on the situation, and the portion between the baffle cover 305 and the duct member 301 enters the portion of the refrigerating chamber shutter 304, which hinders the operation of the shutter and impairs reliability. Question.

Further, in general, there is a refrigerator in which a refrigerator is provided with a switching chamber or the like in addition to a refrigerating compartment, a freezing compartment, and a vegetable compartment, and the switching compartment is capable of switching a cooling temperature zone from a freezing temperature zone to a refrigerating temperature zone ( For example, refer to Patent Document 4).

FIG. 36 shows a conventional refrigerator described in Patent Document 4. As shown in FIG. 36, in the conventional refrigerator 400, in addition to the refrigerating compartment 401, the freezing compartment 402, and the vegetable compartment 403, the storage compartment 404 which becomes a switching chamber, and the ice-making compartment located in the side of the refrigerator compartment are provided. ). In the refrigerator 400, the cooling chamber 405 is disposed rearward of the freezing compartment 402, and a cooler 406 and a cooling fan 407 are provided in the cooling compartment 405.

In the storage chamber 404 and the ice making chamber, cold air is supplied to the respective chambers by the cooling fans 407 located at the rear.

According to the conventional refrigerator 400 described in the patent document 4, since the storage compartment 404 which is switchable from the refrigerating temperature zone to the switching zone of a freezing temperature zone is provided, it is easy to use.

However, the conventional refrigerator 400 described in Patent Document 4 is configured such that a cooling fan 407 supplies cold air to the ice making chamber in which the storage chamber 404 is placed side by side. Therefore, the cooling fan 407 is disposed at a position deviated from the center of the storage chamber 404 toward the ice making chamber side. Therefore, there is a problem that cold air from the cooling fan 406 is supplied to the ice storage chamber side of the storage chamber 404, and there is a problem that cooling is uneven.

In addition, a vegetable compartment baffle is installed in the vegetable compartment pipe. Further, a driving motor for the vegetable compartment baffle is disposed at the side of the vegetable compartment duct. Further, a flapper damper is disposed in the vegetable compartment duct.

With this configuration, the vegetable compartment duct becomes unnecessary to pass through the partition portion that partitions between the refrigerating compartment above the cooling compartment and the freezing compartment. According to this, the length of the pipe can be shortened correspondingly, and the passage resistance can be reduced. Thereby, the amount of cold air circulation can be increased, thereby improving the cooling performance.

In the refrigerator 500 configured as described above, the operation and the effect of the operation will be described below centering on the flow of the cold air.

First, the flow of cold air from the cooling chamber 23 toward the refrigerating chamber 14 and the vegetable compartment 17 will be described.

In the refrigerator 500, when the temperature of the refrigerating compartment 14 becomes higher than the set temperature, the compressor 27 and the cooling fan 25 are driven, and the cold air generated by the cooler 24 is supplied to the downstream side of the cooling fan 25.

The cold air supplied to the downstream side of the cooling fan 25 is supplied to the refrigerating compartment duct 28 through the refrigerating compartment shutter 37 from the first cold air supply port 33 opened to the upper upper surface on the downstream side of the cooling fan 25. Further, the cold air is blown out from the cold air outlets (not shown) opening to the left and right side surfaces of the refrigerating compartment duct 28 to the refrigerating compartment 14 to cool the inside of the refrigerating compartment 14.

In addition, the cold air supplied to the downstream side of the cooling fan 25 is supplied from the second cold air supply port 34 which is opened to the upper side of the downstream side of the cooling fan 25, and is also supplied to the vegetable compartment pipe 30 through the vegetable compartment baffle 75, and is supplied from the vegetable. The lower end opening of the chamber duct 30 is supplied to the vegetable compartment 17 to cool the inside of the vegetable compartment 17.

When the cooling temperature is set such that the temperature of the vegetable compartment 17 higher than the refrigerating compartment 14 reaches the set temperature, the vegetable compartment shutter 75 is closed, and the supply of cold air to the vegetable compartment 17 is stopped, so that the vegetable compartment 17 is maintained at the set temperature.

In this case, the refrigerator 500 of the present embodiment is configured such that the second cold air supply port 34 that supplies cold air to the vegetable compartment 17 and the first cold air supply port 33 that supplies cold air to the refrigerating compartment 14 are individually provided with respect to the cooling chamber 23 . The air supply is independently provided from the cooling chamber 23 directly to the refrigerating compartment duct 28 and the vegetable compartment duct 30 independently. With this configuration, even if the vegetable compartment shutter 75 is closed, the amount of cold air supplied to the refrigerator compartment duct 28 does not change, and the same amount as that when the vegetable compartment shutter 75 is opened is supplied.

Therefore, the cooling of the refrigerating compartment 14 can be performed to the same extent as when the cold air is being supplied to the vegetable compartment 17, and the cooling can be stably performed without being affected by the opening and closing of the vegetable compartment baffle 75.

Further, the vegetable compartment duct 30 is configured to be connected to the downstream side of the cooling fan 25 directly connected to the cooling chamber 23, and is connected to the rear projection area of the first freezing compartment 18 located before the cooling chamber 23, and is connected to Cooling chamber 23. With this configuration, since the vegetable compartment duct 30 does not pass through the partition 5 portion that partitions between the refrigerating compartment 14 above the cooling compartment 23 and the first freezing compartment 18, the length of the duct can be shortened correspondingly, and Resistance to the passage.

According to this configuration, the amount of cold air circulation of the entire refrigerator 500 circulated by the cooling fan 25 can be increased through the vegetable compartment duct 30 and the refrigerating compartment duct 28 and the like. Therefore, it is possible to increase the cooling performance by an amount corresponding to an increase in the amount of cold air circulation.

Here, in order to shorten the length of the vegetable compartment duct 30, the vegetable compartment duct 30 is connected to the cooling compartment within the rear projection area of the first freezing compartment 18, so that the vegetable compartment shutter 75 is located in the first freezing compartment 18 The vegetable compartment baffle loading portion of the vegetable compartment duct 30 protrudes from the side of the second freezing compartment 15 in the range of the rear projection area.

However, in the present embodiment, the vegetable compartment shutter 75 is provided with the vegetable shutter driving motor 76 on the side of the vegetable compartment duct 30, and the barrier damper 75a is provided in the front portion of the vegetable compartment duct 30. Therefore, the wall thickness of the front portion of the vegetable compartment baffle 75 facing the second freezing compartment 15 can be formed with a thinness of only the shutter damper 75a formed of a thin plate, so that it can be suppressed toward the second The protrusion of the freezing compartment 15 is. As a result, the internal volume of the second freezing compartment 15 can be ensured correspondingly, and the depth dimension of the freezing compartment container 62 can be increased.

Further, the vegetable compartment baffle 75 is provided at a height position overlapping the cooling fan 25 of the cooling chamber 23. According to this configuration, the above-described cooling performance improvement effect can be utilized, and the malfunction can be prevented, and the reliability of the refrigerator 500 can be ensured.

That is, since the vegetable compartment 17 is set at a relatively high temperature and the humidity is also in a high state, when the vegetable compartment baffle 75 is closed and the cold air circulation is stopped, there is a humidified cold air having a high humidity from the vegetable compartment 17 The inside is countercurrent to the vegetable chamber pipe 30. There may also be a case where the humidified cold air having a high humidity contacts the vegetable compartment baffle 75 to condense the moisture, and the condensed condensed water is caused by the cooling of the vegetable compartment 17 again. The cold air supplied from the vegetable compartment 17 is frozen, and the vegetable compartment baffle 75 is opened and closed.

However, in the refrigerator 500 of the present embodiment, since the vegetable compartment shutter 75 is provided at a height position overlapping the cooling fan 25, the distance from the vegetable compartment 17 to the vegetable compartment shutter 75 can be secured accordingly, so that it can be upward The distance corresponding to the height dimension of the cooler 24 is pulled apart. Therefore, it is possible to suppress the warming cold air having a high humidity in the vegetable compartment 17 rising in the vegetable compartment pipe 30 to reach the vegetable compartment baffle 75 when the cold air circulation is stopped, and the warming cold air is condensed. Happening.

According to this configuration, it is possible to prevent the vegetable compartment shutter 75 from freezing when the cold air circulation to the vegetable compartment 17 is restarted, thereby causing malfunction, and ensuring reliability.

That is, as in the refrigerator 500 of the present embodiment, the vegetable compartment duct 30 is connected to the cooling chamber 23 within the rear projection area of the first freezing compartment 18 located in front of the cooling chamber 23, and the vegetable compartment shutter 75 is The height position overlapping with the cooling fan 25 is incorporated, whereby the cooling performance can be improved, and the malfunction of the vegetable compartment shutter 75 can be suppressed to ensure reliability. In addition, the volume of the second freezing compartment 15 can also be secured.

Further, in the refrigerator 500 of the present embodiment, the vegetable compartment duct 30 is disposed to overlap the refrigerating compartment return duct 58 from the refrigerating compartment 14 toward the cooling compartment 23 in the front-rear direction. Further, in the refrigerator 500 of the present embodiment, the vegetable compartment duct 30 and the refrigerating compartment return duct 58 are formed of a material having elasticity such as foamed styrene, and are sandwiched between the vegetable compartment duct 30 and the refrigerating compartment return duct 58.

In detail, since the vegetable compartment baffle 75 is held by the vegetable compartment duct 30 and the refrigerating compartment return duct 58 (refer to FIG. 20), first, outside the refrigerator main body 1, the vegetable compartment duct 30 and the refrigerating compartment return duct are installed. 58. Then, the vegetable compartment shutter 75 is covered with the cooler cover 31 adjacent to the vegetable compartment duct 30 with the freezer compartment cover 32 in front, and the vegetable compartment flap 75 is preliminarily inserted between the refrigerator compartment return ducts 58. When the vegetable compartment duct 30 in which the vegetable compartment baffle 75 is placed and the accessory of the refrigerating compartment return duct 58 are placed beside the cooling chamber 23, the vegetable compartment duct 30 can be loaded into the refrigerator main body 1 to improve productivity. .

Moreover, both the vegetable compartment duct 30 and the refrigerating compartment return duct 58 are formed of foamed styrene and have elasticity. According to this, by the elasticity possessed by the vegetable compartment duct 30 and the refrigerating compartment return duct 58, it is possible to fit the vegetable compartment baffle 75 into the vegetable compartment in an airtight state in the cooler cover 31 without using a sealing member or the like. Pipe 30. Therefore, as in the case of the conventional case, when the vegetable compartment baffle is placed in the partition plate, it is not necessary to separately use a sealing member for ensuring airtightness, and the simplification of the configuration and the shortening of the steps become feasible. Can achieve more productivity.

In addition, since the vegetable compartment baffle 75 is elastically supported by the vegetable compartment duct 30 and the refrigerating compartment return duct 58, it is possible to suppress noise generated by microvibration which is likely to occur during opening and closing operations, and the like. Get a quiet and stable refrigerator.

Next, the cooling operation of the refrigerating compartment 14 will be described.

As described above, the refrigerating compartment 14 supplies cold air through the refrigerating compartment duct 28 for cooling. At this time, a part of the cold air supplied to the refrigerating compartment duct 28 is also supplied to the chilling chamber 22 provided in the lower portion of the refrigerating compartment 14 to cool the chilling chamber 22.

The cooling of the refrigerating compartment 14 and the chilling compartment 22 is controlled by the opening and closing of the refrigerating compartment shutter 37, which is maintained at a set temperature, and the refrigerating compartment shutter 37 is actuated according to the output from the refrigerating compartment temperature sensor 59. .

At this time, in the refrigerator 500, as described above, even if the vegetable compartment baffle 75 is opened and closed to control the cooling of the vegetable compartment 17, the amount of cold air supplied to the refrigerating compartment 14 does not change, but is stabilized by a certain amount. . Therefore, the temperature of the chilled room 22 requiring high control precision can be controlled and maintained with high precision as desired. Thereby, the storage quality of the foodstuff in the chilled room 22 and other each compartment in the refrigerator 500 can be improved.

Further, the left and right side portions of the duct cover 28b covering the surface of the duct member 28a on the side of the refrigerating chamber 14 are provided with extending ribs 28bb which are integrally formed with the duct cover 28b and which are formed from the left and right ends Extend to the left and right sides. According to this configuration, it is not easy to directly see the side discharge port 28d on the front side portion of the refrigerator compartment duct 28 from the front side, and the designability in the refrigerator compartment 14 can be improved.

Moreover, the lower surface of the side discharge port 28d has an inclined surface which flows the airflow of the cold air discharged from the side discharge port 28d to the upper side. According to this configuration, the air passage resistance caused by the vortex flow of the cold air flowing out from below can be reduced, and the cooling performance of the refrigerating chamber 14 can be further improved.

On the other hand, the refrigerating compartment duct 28 may cause condensation on the back surface of the heat insulating sheet 38 covering the passage portion 21 due to the cooling action by the cold air flowing through the passage portion 21, and the condensation may drip.

However, as shown in FIG. 11, in the refrigerator 500 of this embodiment, the drain member 40 is provided in the upper part of the installation part of the refrigerating compartment shutter 37 which covers the back surface of the heat insulation sheet 38 of the passage part 21. Therefore, the dripped condensed water is received by the drain member 40, and is drained toward a portion other than the portion where the refrigerating chamber shutter 37 is provided. In the present embodiment, the condensed water is disposed adjacent to the refrigerating chamber duct 28. The chamber return line 58 (see Fig. 4) is drained.

Therefore, it is possible to prevent the condensed water dripping on the back surface of the heat insulating sheet 38 from entering the portion of the refrigerating compartment shutter 37, and it is possible to prevent the operation of the shutter from being hindered. Further, since the condensed water is drained toward the refrigerating compartment return duct 58, the refrigerating chamber return duct 58 is returned to the cooling chamber 23, and the draining process is performed without any trouble by the defrosting operation or the like.

In particular, the heat insulating sheet 38 is adhered to the duct member 28a so as to cover the upper portion of the shutter cover 28c. With this configuration, it is possible to surely prevent the condensed water from intruding into the installation portion of the refrigerating compartment shutter 37 from the joint portion of the upper end portion of the baffle cover 28c and the duct member 28a.

Further, in the refrigerator 500 of the present embodiment, the drain member 40 is adhered to the baffle cover 28c across the heat insulating sheet 38. According to this configuration, it is possible to prevent the heat insulating sheet 38 from peeling off, and it is possible to more reliably prevent the intrusion of the condensed water from the joint portion of the upper portion of the shutter cover 28c.

Further, since the drain member 40 is adhered to the baffle cover 28c across the heat insulating sheet 38, the baffle cover 28c can be strongly fixed. Therefore, even if the configuration is such that only the passage cover 21 of the lower portion of the pipe member 28a is fitted into the baffle cover 28c, the baffle cover 28c can be surely attached and fixed to the duct member 28a. Accordingly, the baffle cover fixing member is not required separately, and the rationalization and simplification of the configuration can be achieved.

Further, since the heat insulating sheet 38 covering the passage portion 21 of the duct member 28a has heat insulating properties, it is possible to reduce the possibility of condensation due to the heat insulating effect, and it is possible to more effectively prevent the blockage caused by the condensed water. Board obstacles.

Further, the refrigerating compartment shutter 37 of the refrigerating compartment duct 28 is provided with a portion of the inner side of the refrigerating compartment 14, that is, the front side of the refrigerating compartment duct 28 is first contacted with the low-temperature cold air supplied from the cooling chamber 23, and is strongly cooled. It is easy to produce condensation. However, in the refrigerator compartment duct 28 of the refrigerator 500 of the present embodiment, the wall thickness of the duct installation portion is formed to be thicker than the thickness of the other portions. With this configuration, it is possible to prevent the temperature from being extremely low. Therefore, even if there is a large amount of use of outside air into the refrigerating compartment 14, for example, when the door 7 is used for a long time in the open state, the refrigerating compartment baffle in the refrigerating compartment duct 28 can be suppressed. 37 Set the condensation in front of the section. Further, in the refrigerator compartment duct 28 of the refrigerator 500 of the present embodiment, the thickness of the portion other than the portion where the refrigerator compartment shutter 37 is provided is formed to be thin. According to this configuration, the volume of the refrigerating chamber 14 can be increased by a portion corresponding to a thinner wall thickness.

As described above, according to the present embodiment, it is possible to eliminate the obstacle caused by the condensation in the refrigerator compartment 14, and it is possible to obtain a highly reliable refrigerator.

Next, the cooling of the second freezing compartment 15 will be described.

The second freezer compartment 15 is cooled by supplying cold air from the downstream side of the cooling fan 25 from the cold air outlet 43a provided in the freezer compartment cover 32 (see FIGS. 16 and 17). The cold air cooled in the second freezing compartment 15 is returned from the chilled cold air return port 64 provided at the lower portion of the first freezing compartment 18 toward the cooling chamber 23.

Here, as shown in FIG. 16 , the cold air outlet 43 a is formed on the front surface of the cold air guiding portion 44 that protrudes forward from the freezing compartment cover 32 and the side surface portion that is opposite to the ice making chamber 16 side. According to this configuration, the cold air from the cooling fan 25 supplied to the second freezing compartment 15 is not only the cold air blown from the cold air blowing port 43a opened in front of the cold air guiding portion 44, but also the opening. The cold air blown by the cold air blowing port 43a on the side opposite to the ice making chamber 16 side of the cool air guiding portion 44.

Therefore, even if the cooling fan 25 is located away from the center of the second freezing compartment 15 toward the ice making compartment 16 side, the cold air from the cooling fan 25 is sufficiently supplied to the side of the tray 45 and the ice making compartment 16 in the second freezing compartment 15. The opposite side. According to this configuration, the cold air is uniformly distributed in the tray 45 in the second freezing compartment 15, and the cooling unevenness of the second freezing compartment 15 can be eliminated.

In particular, in the refrigerator 500 of the present embodiment, the cold air outlets 43a are subdivided and provided in plurality. According to this configuration, the cold air can be dispersed and supplied to the second freezing compartment 15, and the cooling unevenness of the second freezing compartment 15 can be more reliably eliminated.

Further, in the cold air guiding portion 44, in addition to the front surface and the side surface portion opposite to the ice making chamber 16 side, a cold air blowing port 43aa is also provided on the lower surface. With this configuration, cold air can also be supplied to the vicinity of the rear wall portion of the second freezing compartment 15. Therefore, it is possible to prevent condensation which is likely to occur in the back wall portion of the second freezing compartment 15.

Further, as shown in FIG. 18, the tray 45 provided in the second freezing compartment 15 is provided with a plurality of ribs 45a on the bottom surface. With this configuration, the cold air from the cold air outlet 43a is guided by the ribs 45a and efficiently dispersed in the tray 45. Moreover, the cooling plate 47 placed on the rib 45a is formed of a material having good thermal conductivity. With this configuration, the food placed on the cooling plate 47 can be efficiently and uniformly cooled.

In particular, the rib 45a is provided toward the front-rear direction of the tray 45, and the cooling plate 47 is placed on the rib 45a of the front portion. With this configuration, the cold air blown out to the second freezing compartment 15 can be efficiently distributed to the front by the ribs 45a in the front-rear direction, and the food placed on the cooling plate 47 will be located in the second freezing compartment 15 It is easy to take out on the front side, and it is easy to use.

Finally, the cooling of the first freezing compartment 18 will be described.

As shown in FIG. 25, the first freezing compartment 18 is cooled by cold air supplied from the cold air blowing port 63 provided in the freezing compartment cover 32. The cold air cooled in the first freezing compartment 18 is returned to the cooling compartment 23 from the chilled cold air return port 64 provided in the lower portion of the first freezing compartment 18 together with the cold air which cooled the ice making compartment 16 and the 2nd freezing compartment 15.

Here, the refrigerator 500 of the present embodiment is provided with a freezer compartment shutter 68 in the chilled cold air return port 64 of the first freezing compartment 18. With this configuration, the amount of cold air supplied to the first freezing compartment 18 can be controlled. That is, although the first freezing compartment 18 has reached the set temperature, when the temperature of the refrigerating compartment 14 is high and the compressor 27 and the cooling fan 25 are driven, it is possible to prevent the cold air from being supplied to the first freezing compartment 18 and being excessively cooled. Able to achieve good cryopreservation.

In the refrigerator 500 of the present embodiment, in particular, the freezing compartment shutter 68 is not provided on the cold air blowing port 63 side of the first freezing compartment 18 but is provided in the lower portion of the first freezing compartment 18 as shown in FIG. Cold air return port 64 side. Therefore, the simplification of the configuration can be achieved, and a stable shutter operation can be obtained. According to this, the temperature control accuracy of the first freezing compartment 18 can be improved, thereby improving reliability.

That is, the first freezing compartment 18 is provided in front of the cooling chamber 23 and adjacent to the cooling chamber 23 in the front-rear direction. The cold air blowing port 63 provided in the freezer compartment cover 32 that covers the front surface of the cooling chamber 23 communicates with the downstream side of the cooling fan 25 of the cooling chamber 23. With this configuration, during the defrosting operation of the cooler 24, the high-humidity warm air after the defrosting rises in the cooling chamber 23 through the air current to reach the cold air outlet 63. Therefore, if the freezing compartment flap 68 is provided on the side of the cold air blowing port 63, there is a concern that the warming cold air of high temperature and high humidity will come into contact with the freezing compartment flapper 68 and condense, after the defrosting operation ends. When the cooling operation starts again, it will freeze, causing doubts about malfunction. Therefore, in order to prevent this icing, it is necessary to provide a heater for preventing icing in the freezing compartment shutter 68, so that the configuration is complicated.

However, in the refrigerator 500 of the present embodiment, when the freezer compartment shutter 68 is provided in the chilled cold air return port 64 at the lower portion of the cooling chamber 23, most of the high-humidity warm air generated during the defrosting will be generated by the airflow. It is above the chilled air return port 64, and the warm air cooling will continue to rise. Therefore, the warming cold air that is in contact with the freezing compartment baffle 68 is extremely small and the humidity is also small, and the icing caused by the condensation of the warming cold air will also become slight. Moreover, this icing can be prevented by the residual heat generated by the glass tube heater 26 for defrosting. Therefore, the operation of the freezing compartment shutter 68 can be stabilized. Further, since the glass tube heater 26 for defrosting is used, a heater or the like dedicated to defrosting is not required, and the configuration can be simplified. That is, the temperature control accuracy can be improved while the reliability is improved.

In addition, the freezing compartment flapper 68 is worried about the fact that a part of the defrosting water generated at the time of defrosting drops, and enters the terminal take-out portion of the freezing shutter driving motor 72 that drives the freezing compartment shutter 68. The case of the connector terminal portion 79. However, in the refrigerator 500 of the present embodiment, as shown in FIG. 31, the terminal take-out portion of the freezing shutter driving motor 72 is insulated by the two electric insulating plates 80, and is covered by the protective case 81 from above. Further, the opening end side of the protective case 81 is fitted by the sealing member 82, and the sealing member 82 is press-fixed by the support frame piece 83 (refer to FIG. 30) provided in the cooling chamber side port frame portion 66. Therefore, as described above, even if the defrosting water drops, it is possible to prevent the defrosting water from entering the charging portion (the connector terminal portion 79). Therefore, even if the freezer compartment shutter 68 is provided in the chilled-air-cooling-return port 64, it can be used safely without any problem, and a highly reliable cold air control structure can be obtained.

Further, the freezing compartment shutter 68 is fixed by being sandwiched between the cooling chamber cover 31 and the freezing compartment cover 32. The cooling compartment cover 31 and the freezing compartment cover 32 divide the cooling chamber 23 and the first freezing compartment 18. With this configuration, the sealing member 82 of the freezing shutter driving motor 72 provided in the freezing compartment shutter 68 can be fixed by the cooling chamber cover 31 and the freezing compartment cover 32, and the configuration can be simplified.

Further, since the sealing member 82 that seals the charging portion (connector terminal 79) of the freezing compartment shutter 68 is fixed by the freezing compartment cover 32, the fixing structure of the sealing member 82 can be simplified and can be further improved. Seek simplification of the composition.

Further, the freezer compartment shutter 68 is composed of a combination of a plurality of dampers 71. According to this configuration, the front and rear width dimensions of the plurality of dampers 71 can be greatly reduced as compared with the case where the baffle plate is constituted by one damper. Therefore, the freezer compartment shutter 68 itself can be miniaturized, and the space in which the freezer compartment shutter 68 is provided can be greatly reduced, and the volume in the first freezing compartment 18 can be increased accordingly.

Further, the plurality of dampers 71 of the freezer compartment shutter 68 are each disposed to open toward the cooling chamber 23 side. With this configuration, the volume in the first freezing compartment 18 can also be increased. In other words, when a plurality of dampers 71 are provided to be opened toward the first freezing compartment 18 side, each of the plurality of dampers 71 may be in a state of protruding from the first freezing compartment 18 side, and correspondingly, it is necessary to make the freezing compartment container 62. Located in front. Therefore, the volume of the freezer compartment container 62, that is, the volume of the first freezing compartment 18 has to be reduced. However, by forming the configuration of the refrigerator 500 of the present embodiment, such a problem can be eliminated, and the volume of the first freezing compartment 18 can be increased.

Further, as shown in Fig. 28, the cooling chamber side port portion 66 in which the freezing and cooling air return port 64 of the freezing compartment shutter 68 is attached is inclined so as to be located rearward with respect to the vertical line toward the upper side, that is, The more the side is located on the side of the cooling chamber 23. Moreover, the cooling chamber 23 side of the freezer compartment shutter 68 installed in the cooling chamber side port frame portion 66 is inclined so as to be located below the first freezing compartment 18 side of the freezing compartment shutter 68. With such a configuration, the warmed cold air generated in the cooling chamber 23 during the defrosting operation of the cooler 24 may cause the warming cold air to condense even if it comes into contact with the cooling chamber side port portion 66. This condensed water also flows down to the side of the cooling chamber 23, and is drained from the drain port 36 to the outside. Therefore, it is possible to prevent the condensed water from flowing down to the first freezing compartment 18 side, and the ice in the first freezing compartment 18 becomes an ice block and causes an obstacle.

Further, it is generally configured such that, during the defrosting operation, the freezing compartment flap 68 is closed, so that the warming cold air in the cooling chamber 23 does not enter the first freezing compartment 18.

Further, since the freezing compartment shutter 68 approaches the glass tube heater 26 at the lower portion of the cooling chamber 23, the temperature of the freezing compartment shutter 68 rises during the defrosting operation. However, the baffle frame 70, the plurality of dampers 71, and the like constituting the freezer compartment shutter 68 of the refrigerator 500 of the present embodiment are formed of a heat-resistant material. According to this configuration, it is possible to prevent thermal deformation or the like, and it is possible to ensure a good baffle action for a long period of time.

In particular, in the refrigerator 500 of the present embodiment, the lower portion of the freezer compartment shutter 68 (the lower portion of the shutter frame 70) is not disposed directly beside the glass tube heater 26, but is disposed to be located above it. According to this configuration, since the freezing compartment shutter 68 is disposed at a position separated upward from the glass tube heater 26, the direct thermal influence caused by the radiant heat line can be reduced, and the temperature rise can be suppressed. On the other hand, the warmed cold air which is heated by the glass tube heater 26 with less moisture will surely come into contact with the freezer compartment baffle 68, and even if the freezer compartment baffle 68 has frost, the frost will be surely Defrost. According to this configuration, the baffle can be operated very well.

In addition, the distance from the glass tube heater 26 is short, and the lower side 66a of the cooling chamber side port portion 66 that supports the lower portion of the freezing chamber baffle 68 is configured to protrude from the cooling chamber 23 (than the cooling chamber) The bottom surface 23a of the 23 is more protruded from the side of the glass tube heater 26). According to this configuration, it is possible to prevent the radiant heat rays from the glass tube heater 26 from directly irradiating the lower portion of the baffle frame 70 of the freezing compartment shutter 68, thereby preventing an extreme temperature rise. Further, the lower side 66a of the cooling chamber side port frame portion 66 is formed as a double wall, and the gap portion 66b is configured to face the first freezing chamber 18. According to this configuration, by the cooling action by the cold air in the first freezing compartment 18, the extreme temperature rise of the freezing compartment shutter 68 can be prevented, and good operation can be ensured.

Further, as shown in FIG. 26, the freezing compartment shutter 68 is provided at a position where the freezing shutter driving motor 72 does not face the heater portion 26a of the glass tube heater 26, and is disposed in the present embodiment. There is a side of the refrigerating compartment return duct 58 and the vegetable compartment duct 30 beside the cooling chamber 23. With this configuration, it is possible to alleviate the direct thermal influence of the irradiation of the radiant heat rays from the glass tube heater 26 on the freezing shutter driving motor 72. As a result, it is possible to prevent an extreme temperature rise of the freezing shutter driving motor 72, which is a precision component, in which a plurality of gears and the like are incorporated, and it is possible to ensure stable operation of the freezing shutter driving motor 72.

In this manner, the freezing shutter driving motor 72 maintains the state outside the heater portion 26a, and the freezing compartment shutter 68 is disposed such that the freezing shutter driving motor 72 is placed in the refrigerating compartment recirculation beside the cooling chamber 23. Pipe 58 side. With this configuration, a plurality of dampers 71 portions will be located at the center line portion of the cooler 24, so that the cool air flowing back toward the cooling chamber 23 can efficiently contact the cooler 24. As a result, the cooler 24 can fully utilize the original cooling performance of the cooler 24 itself, and the cooling performance can be greatly improved.

Further, the freezing compartment shutter 68 is disposed such that an upper portion thereof (the upper sheet portion of the shutter frame 70) is located above the lower end edge of the cooler 24, and a lower portion thereof (the lower side 66a portion of the shutter frame 70) ) will be located below the lower end of the cooler 24. According to this configuration, the cold air that has flowed back into the cooling chamber 23 can be surely flown to a portion lower than the lower end surface of the cooler 24. Therefore, most of the cold air will flow upward from the lower end surface of the cooler 24, and it is possible to effectively utilize the cooling of the cooler 24 as a whole, and the cooling performance can be further improved.

On the other hand, at the chilled cold air return port 64, a grill 67 is attached to the first freezer compartment 18 side of the freezer compartment shutter 68. The plurality of grid pieces 69 of the grid 67 are each inclined such that the end portion on the side of the cooling chamber 23 is located above the end portion on the side of the first freezing chamber 18. According to this configuration, when the freezer compartment container 62 is pulled out, it is possible to prevent the glass tube heater 26 and the like located behind the grille sheets 69 from being viewed from between the grid sheets 69, and the design can be improved and can be eliminated. The situation is uncomfortable.

Further, the plurality of grid pieces 69 of the grid 67 are formed such that the lower the grid piece 69 is, the longer the front-back length becomes. That is, the plurality of grid pieces 69 are configured to adjust the front and rear lengths of the respective grid sheets 69 so as to follow the shape of the rear surface of the freezer compartment container 62 in the first freezing compartment 18. According to this configuration, the flow of the cold air in the first freezing compartment 18 can be smoothed, and the cooling performance can be improved. Industrial availability

The present invention provides a refrigerator that reduces the total length of a vegetable compartment pipe to suppress a decrease in the amount of cold air circulation, and also minimizes a reduction in the volume of the freezer compartment caused by shortening the entire length of the vegetable compartment pipe, thereby ensuring the volume of the freezer compartment. Refrigerator. According to this, it can be applied to various types and sizes of refrigerators and cooling devices for home use and business use.
