That is, in this embodiment, the 1st partition shelf 211 so that the clearance gap d2 is formed between the uppermost part P3 used as the rear end of the ridge part 413, and the front-end | tip part P1 of the 1st partition shelf 211. FIG. By setting the front and rear lengths of the opening and closing lids 402, the opening and closing cover 402 can be opened large.

In addition, the thickness (up and down height) of the 1st partition shelf 211 and the height of installation set the height dimension d1 so that the upper surface of the 1st partition shelf 211 may substantially correspond with the height of the uppermost part P3. have. As a result, food entering or exiting the first partition shelf 211 touches the tip of the ridge 413 or the first partition shelf 211 to damage the ridge 413 or the first partition shelf 211, Or it reduces the dropping of food, etc., and the spillage of the cup or the like.

In addition, the tip portion P4 of the water supply tank 400 is set in size so as to be located between the tip portion P1 of the first partition shelf 211 and the tip portion P2 of the housing 2.

In addition, in this embodiment, the height H10 from the bottom surface to the upper surface of the lateral compartment wall 4 is set to 830 mm, and the height dimension H1 is 200 mm on the upper surface of the lateral compartment wall 4. The water supply tank 400 is provided. Therefore, in this embodiment, water is supplied to the water supply part 403 arrange | positioned in the position where the height dimension H11 from the bottom surface to the highest part P3 of the water supply tank 400 is about 1000 mm. Since this height is set to the same height as the height of the elbow of a standard adult, the water can be supplied through a plastic bottle or the like without forcing the posture.

In addition, in this embodiment, since the handle part 407 of the water supply tank 400 is also located in the height of about 900 mm, the attachment or detachment of the water supply tank 400 which hold | maintained this handle part 407 is also unreasonable to a user. There is no force.

Next, with reference to FIG. 10, the ease of use in the state set in the refrigerating chamber 210 of this water supply tank 400 is demonstrated concretely. 10 is an operation flowchart for explaining the water supply operation to the water supply tank.

First, the refrigerator 1 called side by side which concerns on this embodiment is a layout structure of the storage room of a standard style in a excluded country. Therefore, when setting the capacity of the water supply tank 400, it is also necessary to consider the consumption of the excluded countries. For example, if you examine the use of homogeneous side-by-side refrigerators in the UAE and Saudi Arabia of the Near and Middle East countries, as a result of 100 households, the number of times you drink cold water is up to 10 times per day, 1 The amount of meetings is 200 kW, and the maximum consumption is 2 L per day. In addition, if the frequency of use of ice is to extract ice up to 11 to 12 times a day, and 100 kPa at a time, there is a maximum consumption of 1.1 L to 1.2 L per day.

Therefore, in the present embodiment, the capacity of the water supply tank 400 is set to 3.5 L to 4 L by adding an extra amount of plus alpha to 3.2 L of the total consumption of cold water and ice making. In addition, in this embodiment, the capacity | capacitance of an ice accommodating part is set to 1.7L in consideration of the use frequency of ice. If it is this capacity | capacitance, even if the usage-amount of ice increases, it can respond. And if it is this 4 L water supply tank 400, even if it is sufficient capacity | capacitance of this ice, since 2.3 L of cold water is ensured, even if the consumption amount of the said cold water increases to some extent, it can respond.

The water supply tank 400 according to the present embodiment can be separated from the refrigerating chamber 210 to supply water from the tap water or to allow internal cleaning, but there is a problem in frequently separating the heavy water supply tank 400. Therefore, in this embodiment, as shown in FIG. 10, even in a state where the water supply tank 400 is set in the refrigerating chamber 210, water can be supplied in a comfortable posture.

That is, in FIG. 10, when the refrigerating compartment door 60 is opened, as shown in FIG. 10A, the water supply tank 400 is set at the lower left side of the refrigerating compartment 210. In this set state, the water supply part 403 closed by the opening / closing cover 402 is exposed in the front part of the 1st partition shelf 211. As shown in FIG. If this water supply part 403 is closed, dust will not mix in the water supply tank 400 when entering and leaving food to the 1st partition shelf 211. FIG. Moreover, since the inclined surface 412 provided with the water supply part 403 is continuous with the 1st partition shelf 211 without a step | step, the container which loaded food hits the water supply tank 400, and reduces food falling. You can. In addition, since the 1st partition shelf 211 is made transparent, the food in the refrigerator compartment 210 can be monitored to every corner.

From the state of FIG. 10A, as shown in FIG. 10B, when the opening / closing button 415 provided in the uppermost part of the upper surface of the feed water tank 400 is operated, FIG. As shown in FIG. 2, the opening and closing cover 402 is opened rearward, and as shown in FIG. 10D, the opening and closing cover 402 can be opened. That is, the opening / closing cover 402 can be opened easily by one touch.

In the open state of FIG. 10D, the water supply part 403 is greatly opened, and the opening / closing cover 402 is in a standing position at the rear thereof, so that the first partition shelf 211 and the water supply part 403 are opened. Can be clearly separated. In addition, since the front of the water supply portion 403 is lower than the rear side, as shown in Fig. 10E, water inlet can be easily provided by injecting a plastic bottle inlet in front of the water supply portion 403. have.

In addition, as shown in FIG. 7C, the water injected from the water supply unit 403 is reduced by the lower inclined surface 405 to the user side, and the spring to the rear is in the standing position. It is prevented and reduced by the opening / closing cover 402. In addition, at the time of water supply, since the open state of the opening-closing cover 402 is maintained, water can be supplied while holding a plastic bottle with both hands.

Then, as shown in Fig. 10F, when the water supply is finished, the opening / closing cover 402 is closed, and the tip of the opening / closing cover 402 is locked by the opening / closing button 415. The closing operation can be performed.

Next, referring to Figures 11 and 12, the specific structure of the lower storage pocket 220 adjacent to the water supply tank 400 will be described. Here, Fig. 11 is an external view showing the installation state of the lower storage pocket, Fig. 11A is an external perspective view of the refrigerating chamber door in which the lower storage pocket is installed, and Fig. 11B shows the opening and closing state of the refrigerator compartment door. It is a cross-sectional view. 12 is an external view of the lower storage pocket, FIG. 12A is a perspective view from the front, and FIG. 12B is a perspective view from the rear.

11 and 12, in a very general refrigerator having a refrigerating compartment at the top, storage pockets are provided on the inner wall of the refrigerating compartment door to improve storage. In particular, since the storage pocket provided in the lower part of the inner wall of the refrigerating compartment door is at the height which is convenient to use, a large storage pocket is provided by securing a large space in the front part of a partition shelf.

Also in the refrigerator 1 which concerns on this embodiment, the large lower storage pocket 220 is arrange | positioned under the inner wall of the refrigerating chamber door 60. As shown in FIG. However, in this embodiment, since the front-end | tip part (projection part 401) of the water supply tank 400 protrudes in front of the 1st partition shelf 211, it is in the environment where it is difficult to provide a large storage pocket.

Therefore, in this embodiment, the lower storage pocket 220 which cut | disconnected the large storage pocket and the part which the water supply tank 400 wraps, and formed the notch 221 is employ | adopted. The cutout portion 221 has a suitable gap such that the lower storage pocket 220 does not come into contact with the water supply tank 400 even when the refrigerating compartment door 60 is opened or closed, and has a large rounding at the corner portion.

11A and 12 show the appearance of the lower storage pocket 220 having such a feature. The lower storage pocket 220 has a structure in which both sides are fitted and installed in the installation ribs 66 formed on both sides of the inner wall surface of the refrigerating compartment door 60 in the same manner as the other storage pockets 219. For this reason, the width | variety of the lower storage pocket 220 is set to the same length as the width | variety of the other storage pocket 219, and the installation groove | channel 223 which the upper end part is closed and the downward opening is provided in the both side wall is provided.

According to this structure, the lower storage pocket 220 can be installed in the refrigerating compartment door 60 by fitting it from the upper part through the installation groove 223 to the installation protrusion which is not shown in the installation rib 66. . In addition, with this structure, since the lower storage pocket 220 can be replaced with another storage pocket, development to the model which does not employ the water supply tank 400 is possible.

Thus, the lower storage pocket 220 according to the present embodiment employs the cutout portion 221, whereby the first storage portion 426 having a large depth dimension and the depth dimension formed adjacent to the cutout portion 221. Has a small second housing portion 427. For this reason, the large 1st accommodating part 426 can accommodate large foods, such as a plastic bottle and a beer bottle, and the small 2nd accommodating part 427 can accommodate small foods with a frequency of use.

In addition, the lower storage pocket 220 has a structure in which the inner side of the refrigerating chamber door 60 is used as the rear wall by opening the rear surface side. In addition, the lower storage pocket 220 is divided into two vertically, the upper portion is formed of a transparent resin material, and the lower portion is formed of an opaque resin material. This makes it easy to check the inside through the transparent part even when food having a short length is stored while concealing dust collected on the floor.

Next, with reference to FIG. 9, FIG. 13, and FIG. 14, the upper drawing container 264 of the vegetable chamber 260 is demonstrated. Here, FIG. 13 is a cross-sectional view showing the withdrawal structure of the top takeout container. 14 is a contrast diagram of the top takeout container and another takeout container.

First, in FIG. 9, in this embodiment, the casing accommodation space 261 of the vegetable chamber 260 is made into the several sealed storage space comprised from the several draw container 263. In FIG. Specifically, the housing storage space 261 is divided into three parts up and down, and the upper end is made up of the upper drawer container 264 provided with the opening and closing cover 265, and the middle end and the lower end are made up of the container 268a with the upper part open. It is set as the intermediate | middle stage drawing container 267a and the lower stage drawing container 267b. These top and bottom three-stage takeout containers 263 can be moved in and out of the housing storage space 261 by moving in the front-rear direction through support rails (not shown) provided on the inner wall surfaces of both sides of the vegetable chamber 260.

In addition, in this embodiment, in order to form the sealed storage space, the upper drawing container 264 is covered upward by the horizontal partition wall 4 in a storage state. The intermediate stage take-out container 267a and the bottom take-out container 267b are disposed below the top take-out container 264 and include a sealing cover 269 covering the upper portion of the container 268a.

In addition, in this embodiment, in order to ensure the storage capacities of the three drawing containers 263 similarly, the lower end drawing container 267 of the lower end draw container 267 by which the storage capacity is reduced by the presence of the machine room 12 of the housing | casing 2 is carried out. A space 270 is formed in the front portions of the intermediate stage take-out container 267a and the top take-out container 264 by protruding forward to the front end portion P2, and the door storage space ( 262).

In Fig. 13, the upper lead-out container 264 according to the present embodiment is disposed adjacent to the lower side of the horizontal partition wall 4, and the vegetable chamber 260 is provided to secure the door storage space 262 in the front portion thereof. Is placed in the rear of the. In addition, since the refrigerator 1 which concerns on this embodiment is equipped with the automatic ice-making apparatus 300, the ice storage part 320 and the blower outlet 350 are provided in the freezer compartment door 50. As shown in FIG. For this reason, there exists a thickness of the freezer compartment door 50, and the thickness of the refrigerating compartment door 60 also inevitably becomes large. Therefore, in the upper lead-out container 264, the length D10 of the door surface 9 of the refrigerating compartment door 60 and the front end of the upper lead-out container 264 located in the front part of the horizontal partition wall 4 is Since it becomes an obstacle when entering and leaving a food, there exists a subject that food cannot enter and exit from the top taking out container 264 unless it pulls out the top taking out container 264 forward beyond this obstacle.

However, in the case where the top takeout container 264 is pulled forward, the top takeout container 264 cannot be held unless it is partially wrapped with support rails (not shown) formed on both inner wall surfaces of the vegetable chamber 260. Since there exists a subject, there exists a limit to the solution which draws out the top draw container 264 largely forward.

So, in this embodiment, the front surface of the top drawing container 264 is opened with movement to the front of the top drawing container 264, and it opens and closes stored below the horizontal partition wall 4 at the time of opening. The cover 265 is adopted. That is, in this embodiment, the upper side is opened and the front side is obliquely cut, the storage container 271, the opening-closing cover 265, and this opening-closing cover 265 through both sides of the movable guide means 272. It comprises a side plate 273 supported by the.

The movable guide means 272 includes an upper support protrusion 274a and a lower support protrusion 274b formed at upper and lower ends of both sides of the opening and closing cover 265, and a first support rail 275a supporting two protrusions from both sides. And a second support rail 275b. The first support rail 275a is a groove formed toward the rear, and supports the upper support protrusion 274a from both sides, and moves the upper support protrusion 274a in a substantially horizontal direction. On the other hand, the second support rail 275b is a groove formed in the vertical direction, and supports the lower support protrusion 274b from both sides, and moves the lower support protrusion 274b in the approximately vertical direction.

As shown in Fig. 13A, the opening / closing cover 265 is held in a vertical position so as to prevent the cut front surface portion of the storage container 271 in the stored state. On the other hand, as shown in Fig. 13C, in the state where the upper lead-out container 264 is taken out, it is held in a horizontal position between the lateral compartment wall 4 and the intermediate stage lead-out container 267a.

Next, with reference to FIG. 13, the opening / closing operation | movement of the opening / closing cover 265 accompanying movement of this upper drawing container 264 is demonstrated more concretely.

First, in the state where the upper lead-out container 264 shown in FIG. 13A is housed, the front surface of the upper lead-out container 264 is the front part of the storage container 271 provided with the handle part 276. It is covered by the opening-closing cover 265 in a vertical posture arranged above it. From this state, when the storage container 271 is pulled out through the handle part 274 forward, the guide rail of the upper wall surface which the lower end part of the opening-closing cover 265 of the vertical posture was obliquely cut on both sides of the storage container 271 ( 277) is pressed forward. However, the lower end of the opening / closing cover 265 is prevented from moving forward by fitting the lower support protrusion 274b and the second support rail 275b, and the stress supports the lower support protrusion 274b for the second time. It moves upward along the rail 275.

In connection with this, the upper support protrusion 274a moves rearward along the 1st support rail 275a. As the storage container 271 moves forward by this operation, the lower end of the opening / closing cover 265 moves on the guide rails 277 and moves upwards. As a result, as shown in FIG. As described above, the opening / closing cover 265 is accommodated in a horizontal position between the horizontal partition wall 4 and the moved storage container 271.

Moreover, when the storage container 271 is pushed in like FIG.13 (c) from FIG.13 (b), the opening / closing cover 265 supported by the guide rail 277 also has a guide rail by its own weight. It gradually descends along 277 to (c) in FIG. 13, and returns to the original storage state as shown in FIG.

Fig. 14B shows a prior art having a storage container 271a with an open top. According to this prior art, since the storage container 271a can access the food only from above, the food entrance space D20 formed between the upper end of the front surface of the opening of the storage container 271a and the lower end of the refrigerating compartment door 60. ) There is problem that becomes narrow.

However, as shown in Fig. 14A, in this embodiment, since the wall surface of the front portion of the storage container 271 is cut, the front upper end of the front portion of the opening of the storage container 271 and the refrigerating chamber door 60 The food in / out space D20 formed between the lower end portions can be made larger than that of the prior art in Fig. 14B. In addition, in this embodiment, since the opening-closing cover 265 is concealed below the horizontal partition wall 4, it does not interfere with the food in and out.

The refrigerator 1 having the above-described configuration includes a first storage part 100 and a second storage part 200 in which the housing 2 having an open front is arranged in the width direction by a vertical partition wall 3 having a heat insulating material. Each storage part (100, 200) is closed by the door (50, 60, 70) which is installed through the hinge portion 5 on both sides of the width direction of the housing (2), the first storage part The dispenser unit 80 capable of supplying water to the door 50 to close the 100 is installed, and the door 50 to close the first storage unit moves the first storage unit 100 in the vertical direction. It is constituted by a single door 50 to be closed throughout, and the plurality of doors 60 and 70 are installed side by side in the vertical direction in the second storage part 200. Therefore, when storing or taking out goods in the second storage unit 200, only the corresponding doors 60 or 70 need to be opened.

By the way, the water provided in the dispenser unit 80 is blown from the outside of the door 50, specifically, for cold water from the outside of the door 50 to the dispenser unit 80 through the hinge portion 5 The water supply pipe 7 is formed. However, since the hinge part 5 is a part which becomes an axis | shaft when the door 50 opens and closes, piping to this part is not easy. In this regard, in the refrigerator 1 having the above-described configuration, since the door 50 closes the first storage part 100 over the entire up and down direction (that is, the outer door), the hinge part that needs to be piped ( 5) can be fixed to only one necessary place. Therefore, the structure of the refrigerator 1 can be simplified, and the ease of manufacture and maintainability can be improved.

In addition, a water supply tank 400 for supplying water provided from the dispenser unit 80 is installed in the second storage unit 200, and the water supply tank 400 may include a second storage unit 200. It can be handled from the open front side, and the said water supply tank 400 is arrange | positioned in the up-down position corresponding to any one of the said door 60, 70 among the said 2nd storage part 200. FIG. Therefore, when handling the water supply tank 400, only one of the plurality of doors 60, 70 arranged in the vertical direction may be opened. In addition, as the operation | movement which handles the water supply tank 400, although the various operation | movement which targets the water supply tank 400 can be considered, the operation | movement which draws out the water supply tank 400 as mentioned above out of a ship or water supply specifically, The operation | movement, such as replenishing water, in the state which arrange | positioned the tank 400 to the 2nd storage part 200 is mentioned.

In addition, the water supply tank 400 is disposed in the middle portion of the vertical direction of the second storage unit 200. Here, the vertical direction middle portion of the second storage portion 200 corresponds to the height of the general user's hand, and thus easily extends the hand naturally. Therefore, forcing a user into an unreasonable posture when handling the water supply tank 400 is reduced.

In addition, the water supply tank 400 is disposed in the vicinity of the vertical section wall (3). For this reason, the water supply tank 400 is arrange | positioned in the position on the opposite side to the hinge part 5 in the 2nd storage part 200 in the width direction. Therefore, as shown in Fig. 17, the space required for handling the water supply tank 400 can be obtained only by slightly opening the door 60 or 70, which closes the second storage part 200, without opening it completely. It can be secured. For example, an operation such as opening the door 60 with the right hand and withdrawing the empty water supply tank 400 with the left hand can be performed.

Second Embodiment

Next, with reference to FIG. 19, the refrigerator 1b which concerns on 2nd Embodiment is demonstrated concretely. Here, FIG. 19 is a schematic view of the refrigerator according to the second embodiment, FIG. 19A is a front view of a state in which the door is opened, and FIG. 19B is a vertical partial sectional view of the freezer compartment. In addition, the same part, arrow, etc. as 1st Embodiment are demonstrated with the same code | symbol, and the overlapping description is abbreviate | omitted.

In the first embodiment described above, the automatic ice maker 300 is installed on the ceiling surface of the housing storage space 105 of the freezer compartment 100, and the ice generated by the automatic ice maker 300 is stored in the freezer compartment door 50. Although it was set as the structure which receives and accumulate | stores in the ice accommodating part 320 provided in the inner wall surface of this, it is not limited to this in this embodiment. For example, as shown in FIG. 19, the structure which installs the automatic ice-making apparatus 300 and the ice accommodating part 320 in the inner wall surface of the freezer compartment door 50 is applicable.

In this case, the connection between the ice maker pump 473 and the automatic ice maker 300 of the tank base 470 is connected to the water supply pipe 6 for ice making through the hinge portion 5 of the upper part of the freezer door 50. Pipe it. In addition, the ice-making water supply pipe 6 in the freezing chamber 100 allows the inside of the heat insulating material of the housing 2 to be piped so that the cold water in the ice-making water supply pipe 6 does not freeze.

In addition, about another structure, since it is common to the said 1st Embodiment, description is abbreviate | omitted.

Third Embodiment

Next, a third embodiment will be described with reference to FIGS. 20 to 24. 20 is a sectional perspective view of the refrigerating compartment 210 and the vegetable compartment 260. Fig. 21 is a perspective view of the vegetable chamber duct 280 of the vegetable chamber 260, the upper lead container 264, the intermediate stage lead container 267a, and the lower lead container 267b. 22 is an exploded perspective view of the vegetable chamber duct 280. 23 is a partial sectional view of the refrigerating compartment and the vegetable compartment. FIG. 24 is a partially enlarged view near the vegetable chamber duct of FIG.

20 shows a state in which the vegetable chamber duct 280 of the vegetable chamber 260, the upper end drawing container 264, the middle end drawing container 267a, the lower drawing container 267b, and the like are separated. The rear wall 22d is provided with a vegetable chamber ejection opening 22d1 for ejecting cold air into the vegetable chamber. Specifically, a plurality of vegetable chamber ejection openings 22d1 are provided in the vertical direction of the rear wall 22d. Thereby, the temperature change in the vegetable chamber 260 can be suppressed, and what is called a temperature nonuniformity in which the inside of the vegetable chamber 260 becomes partly high temperature or partly becomes low temperature can be suppressed.

In addition, as shown in Fig. 23, the vegetable chamber ejection opening 22d1 has a height corresponding to the vegetable chamber duct 280, the upper end drawing container 264, the intermediate stage drawing out container 267a, and the lower drawing container 267b, respectively. It is installed.

In addition, the vertical compartment wall 3 is provided with a vegetable compartment and a cold air return port 22d2. Specifically, 22 d2 of vegetable chamber cold air return ports are provided in the position of the height where the intermediate | middle stage drawout container 263 is provided. The vegetable chamber cold air return port 22d2 communicates with the cooling chamber 16 behind the freezing chamber 100. That is, the vegetable chamber cold air return port 22d2 is almost the same height as the height in which the cooling chamber 16 is installed, and is installed in the height which cold air flows below the heat exchanger 13.

As a result, the cold air ejected from the vegetable chamber outlet 22d1 into the vegetable chamber 260 flows from the vegetable chamber cold air return port 22d2 to the cooling chamber 16, flows from the lower side of the heat exchanger 13 upwards, and heat exchanges again. It is a circulation structure ejected at 260.

In the vegetable chamber 260, as shown in FIG. 21, the upper end drawing container 264, the intermediate | middle stage drawing container 267a, and the lower drawing container 267b are provided from the top. In addition, the vegetable chamber duct 280 is provided above the upper drawer 264. Any draw container is adapted to form a closed space in which gas movement is suppressed so that cold air is not blown directly into the storage. And, as shown in Figs. 20, 23, and 24, the vegetable chamber ejection opening 22d1 has a vegetable chamber duct 280, a lower end of the upper lead-out container 264, a lower end of the intermediate stage lead-out container 267a, and a lower lead-out container ( 267b) are provided at the rear, respectively. That is, the vegetable chamber 260 is configured to prevent the storage from being dried by indirect cooling, thereby preventing the humidity of the storage space from lowering.

As shown in Fig. 22, the vegetable chamber duct 280 provided above the upper lead-out container has the upper lead-out container upper wall member 280a, the insulator 280b for the vegetable chamber duct, the vegetable chamber duct frame 280c and the thermoelectric from below. It is the structure which has the conductive panel 280d.

The upper lead-out container upper wall member 280a is a member constituting the upper wall of the upper lead-out container 264. As shown in Fig. 24, a cold air passage is formed in the vegetable chamber duct insulator 280b so that the cold air ejected from the vegetable chamber ejection opening 22d1 flows from the rear of the upper end drawing container upper wall member 280a to the front. Specifically, as shown in Fig. 22D, a plurality of convex portions 280b1 are provided on the lower surface of the heat insulating material 280b for vegetable chamber ducts. And a cold air path is formed by combining the upper drawing container upper wall member 280a and the vegetable compartment duct heat insulating material 280b. That is, the upper surface of the upper drawing container upper wall member 280a forms one surface of the cold air passage, and the vegetable chamber duct heat insulating material 280b forms the upper surface and the side surface of the cold air passage. The vegetable chamber duct frame 280c and the upper lead-out container upper wall member 280a are coupled with screws 280e, and the vegetable chamber duct insulation 280b is installed in the space formed thereby.

As a result, it is possible to suppress the blowing of cold air directly into the stock of the upper lead-out container 264 to indirectly cool it, and to allow the cold air to flow from the rear of the vegetable chamber to the front.

Moreover, the thermally conductive panel 280d is provided above the vegetable chamber duct heat insulating material 280b through the vegetable chamber duct frame 280c. The vegetable chamber duct frame 280c and the upper lead-out container upper wall member 280a are made of resin, while the thermally conductive panel 280d is made of metal (eg, aluminum). In addition, as shown in FIG. 23, a return passage 22 through which cold air blown into the refrigerating compartment 210 passes is provided in the horizontal partition wall 4 that divides the vegetable compartment 260 and the refrigerating compartment 210. As shown in FIG. 24, the thermally conductive panel 280d is provided in the vicinity of the horizontal partition wall 4 below. In other words, the thermally conductive panel 280d is provided near the return passage 22. Thereby, the thermal conductive panel 280d is cooled by cold air passing through the return passage 22. Therefore, even when there is no supply of cold air in the vegetable chamber 260 during the injury prevention operation of the heat exchanger 13, the temperature change in the vegetable chamber 260 can be suppressed by the radiant heat of the low-temperature thermal conductive panel 280d. As a result, the load applied to the storage can be reduced by changing the temperature.

Further, even when there is no supply of cold air in the refrigerating compartment 210 during defrosting operation of the heat exchanger 13, the refrigerating compartment 210 is formed by the radiant heat of the radiation plate 222 and the thermal conductive panel 280d provided on the rear surface of the refrigerating compartment. It is possible to suppress the temperature change in the crest and to reduce the load applied to the storage by the temperature change.

In addition, about another structure, since it is common to the said 1st Embodiment, description is abbreviate | omitted.

Next, a fourth embodiment will be described with reference to FIGS. 25 to 27. 25 is a longitudinal sectional view of the freezing compartment 100. 26 is a longitudinal cross-sectional view of the refrigerating chamber 210. 27 is a plan sectional view of the freezing compartment 100 and the refrigerating compartment 210.

In this embodiment, the cooling chamber 16 is installed behind and behind the freezer compartment 100, and the machine room 12 is installed behind and behind the refrigerator compartment 210. In other words, the cooling chamber 16 and the machine room 12 are installed side by side to the left and right of the rear lower part of the refrigerator 1. In this embodiment, two heat exchangers 13 are provided in the cooling chamber 16 side by side in the front-rear direction, and defrost heaters 17 and 17 are provided below each. That is, the lower part of the freezing chamber 100 becomes a shape which protrudes forward only by the dimension by which the heat exchanger 13 is installed. Therefore, the machine room 12 is provided in the rear of the refrigerating chamber 210 so that the height position and the front-back direction position of the protruding shape of this freezer compartment 100 are matched. Thereby, the storage volume of the freezer compartment 100 and the refrigerating compartment 210 can be balanced and designability can be improved.

In general, since the freezing chamber 100 has a lower temperature than the refrigerating chamber 210, the machine chamber 12 that becomes hot is provided at the rear of the refrigerating chamber 210, and the cooling chamber 16 is located at the rear of the freezing chamber 100. By installing in, the influence of the temperature from the machine room 12 is reduced. Thereby, cooling efficiency can be improved. That is, the energy required for cooling can be reduced.

In the present embodiment, the freezing chamber 100 and the refrigerating chamber 210 are divided left and right by the vertical partition wall 3, but a structure in which the vegetable chamber is further provided below the refrigerating chamber 210 may be used. In this case, the machine room 12 is provided behind the vegetable room and below.

In addition, in this embodiment, although the machine room 12 is provided in the back and below the refrigerating chamber 210, the structure which installs the machine room 12 in the rear and upper direction of the refrigerating chamber 210 may be sufficient. Thereby, while using the upper back of the refrigerating chamber 210 which is a space which is hard to reach, it can improve the ease of use.

Next, the flow of cold air in the freezing chamber 100 will be described. Above the cooling chamber 16, a freezing chamber rear passage 18 is provided over the entire rear of the freezing chamber 100. In addition, a plurality of intermediate cold air ejection openings 104 are provided in the freezer compartment rear passage 18 at positions corresponding to the heights of the plurality of partition shelves 101. In addition, a blower fan 14 is provided above the freezer compartment back passage 18. An upper cold air jet port 103 is provided in the freezer compartment rear passage 18 at the height position of the blower fan 14. In addition, a freezer compartment cold air return port 19a is provided at the lower rear portion of the freezer compartment 100. The freezer compartment cold air return port 19a communicates with the cooling chamber 16 and is provided at a position where cold air flows from below the heat exchanger 13.

As a result, the cold air heat-exchanged by the heat exchanger 13 of the cooling chamber 16 flows upward from the freezing chamber rear passage 18, and the blower fan 14 provides the intermediate cold air jet 104 and the upper cold air jet 103. Is ejected into the freezing chamber 100 from the. The cold air ejected into the freezer compartment 100 is a circulation structure that is returned from the freezer compartment cold air return port 19a to the cooling chamber 16, heat exchanges with the heat exchanger 13, and is ejected back into the freezer compartment 100. In this way, the blower fan 14 is installed at the top of the freezer compartment rear passage 18 and the freezer compartment cold air return port 19a is installed at the bottom of the freezer compartment 100, whereby cold air is circulated in the entire upper and lower portions of the freezer compartment 100. The cooling efficiency in the freezer compartment 100 can be improved.

Next, the flow of cold air in the refrigerating chamber 210 will be described. The communication air path 21 which communicates with the refrigerating chamber 210 is provided in the height position of the blowing fan 14 of the vertical block wall 3. At the rear of the refrigerating chamber 210 and at the upper portion, an upper cold air jet port 213 is connected to the communication air passage 21 and blows cold air into the refrigerating chamber 210. Moreover, the refrigerator compartment cold air return port 22d4 is provided in the lower part of the vertical division wall 3, and the refrigerator compartment 210 side. The refrigerating chamber cold air return port 22d4 is connected to the refrigerating chamber cold air return duct 22d3 provided in the vertical compartment wall 3 and communicates with the cooling chamber 16.

Thereby, the cold air heat-exchanged by the heat exchanger 13 of the cooling chamber 16 flows upwards in the freezer compartment back surface path 18, and communicates with the cold air blown into the freezing chamber 100 by the blower fan 14, 21 Branch into cold air flowing through The cold air flowing through the communication air passage 21 is ejected from the upper cold air jet port 213 to the refrigerating chamber 210, and is returned from the refrigerating chamber cold air return port 22d4 to the cooling chamber 16 after passing through the refrigerating chamber cold air return duct 22d3. And it heat-exchanges with the heat exchanger 13, and is a circulation structure which cool air blows out to the refrigerating chamber 210 again.

In this way, since the upper cold air jet port 213 is provided at the top of the refrigerating compartment 210, and the refrigerating compartment cold air return port 22d4 is provided at the lowermost part of the refrigerating compartment 210, cold air is circulated over the entire upper and lower sides of the refrigerating compartment 210. Thus, the cooling efficiency in the refrigerating chamber 210 can be improved. In addition, in the case where the refrigerating chamber 210 divides the upper part into the refrigerating chamber and the lower part into the vegetable chamber, the same effect can be obtained by providing the cold air return port on the lower side of the vertical partition wall 3 and on the vegetable chamber side.
