  First, the refrigerator 1 called side-by-side according to this embodiment has a standard style storage room layout configuration in various countries. Therefore, when setting the capacity of the water supply tank 400, it is necessary to consider the consumption of other countries. For example, when we investigated the actual usage of side-by-side refrigerators of the same type in UAE and Saudi Arabia in the Middle Eastern countries, the results for 100 households showed that the maximum number of cold water drinks was 10 times a day. If the amount is 200cc, there is a maximum consumption of 2L per day. Also, if ice is used at a maximum frequency of 11 to 12 times a day and 100 cc at a time, the maximum consumption is 1.1 to 1.2 L per day.

  Therefore, in this embodiment, the capacity of the water supply tank 400 is set from 3.5 L to 4 L by adding an extra amount of plus alpha to the total consumption amount 3.2 L of the cold water and ice making. In this embodiment, the capacity of the ice storage unit is 1.7 L in consideration of the usage frequency of ice. This capacity can cope with an increase in the amount of ice used. And if it is this 4L water supply tank 400, even if this sufficient capacity of ice is ensured, 2.3L of cold water is ensured, so it is possible to cope with a slight increase in the consumption of the cold water. .

  Although the water supply tank 400 which concerns on this embodiment removes from the refrigerator compartment 210 and supplies water from a water supply, or internal cleaning is possible, there exists a subject in removing the heavy water supply tank 400 frequently. Therefore, in this embodiment, as shown in FIG. 10, water can be supplied in an easy posture even when the water supply tank 400 is set in the refrigerator compartment 210.

  That is, in FIG. 10, when the refrigerator compartment door 60 is opened, the water supply tank 400 is set on the lower left side of the refrigerator compartment 210 as shown in FIG. In this set state, the water supply part 403 closed by the opening / closing lid 402 is exposed at the front part of the first partition shelf 211. If the water supply unit 403 is in a closed state, dust does not enter the water supply tank 400 when food is taken in and out of the first partition shelf 211. Moreover, since the inclined surface 412 provided with the water supply unit 403 is continuous with the first partition shelf 211 without a step, it is possible to reduce the drop of food by the container on which the food is placed hitting the water supply tank 400. Furthermore, since the 1st partition shelf 211 is transparent, the foodstuff in the refrigerator compartment 210 can be monitored all over.

  Now, when the open / close button 415 provided on the uppermost front surface of the water supply tank 400 is operated from the state shown in (a), as shown in (b), the open / close lid 402 is moved backward as shown in (c). (D) and the opening / closing lid 402 can be opened as shown in FIG. That is, the opening / closing lid 402 can be easily opened with one touch.

  In the open state of FIG. (D), the water supply unit 403 is largely opened, and the opening / closing lid 402 is in a standing posture behind it, so that the first partition shelf 211 and the water supply unit 403 can be clearly separated. it can. Further, since the front side of the water supply unit 403 is lower than the rear side, as shown in (e), water can be easily supplied with a spout of a plastic bottle attached in front of the water supply unit 403. .

  In addition, as shown in FIG. 7C, the water poured from the water supply unit 403 is less bounced to the user side by the lower inclined surface 405, and the bounce back is the open / close lid 402 in a standing posture. Is prevented and reduced. In addition, when the water is supplied, the open / close lid 402 is kept open, so that water can be supplied while holding the plastic bottle with both hands.

  And as shown in (f) figure, when water supply is complete | finished, since the front-end | tip of the opening-and-closing lid 402 will be in a locked state by the opening-and-closing button 415 by the operation | movement which closes the opening-and-closing lid 402, closing operation can be performed by one touch.

  Next, a specific structure of the lower storage pocket 220 adjacent to the water supply tank 400 will be described with reference to FIGS. 11 and 12. Here, FIG. 11 is an external view showing a state in which the lower storage pocket is attached, (a) is an external perspective view of the refrigerator compartment door with the lower storage pocket attached, and (b) is an open / closed state of the refrigerator compartment door. FIG. 12A and 12B are external views of the lower storage pocket, where FIG. 12A is a perspective view seen from the front, and FIG. 12B is a perspective view seen from the rear.

  11 and 12, in an extremely general refrigerator having a refrigerator compartment at the top, a storage pocket is provided on the inner wall of the refrigerator compartment door to improve the storage performance. In particular, since the storage pocket provided in the lower part of the inner wall of the refrigerator compartment door is easy to use, a large storage pocket is provided by securing a large space in the front part of the partition shelf.

  Also in the refrigerator 1 according to this embodiment, a large lower storage pocket 220 is disposed at the lower part of the inner wall of the refrigerator compartment door 60. However, in this embodiment, since the tip end portion (the overhang portion 401) of the water supply tank 400 is formed so as to protrude in front of the first partition shelf 211, it is difficult to provide a large storage pocket. .

  Therefore, in this embodiment, a lower storage pocket 220 in which a cutout portion 221 is formed by cutting out a portion where the large storage pocket and the water supply tank 400 wrap is adopted. The notch 221 has an appropriate gap so that the lower storage pocket 220 does not come into contact with the water supply tank 400 even when the refrigerator door 60 is opened and closed, and the corner is formed with a large roundness.

  FIG. 11A and FIG. 12 show the appearance of the lower storage pocket 220 having such characteristics. The lower storage pocket 220 has a structure in which both sides are fitted and attached to mounting ribs 66 formed on both sides of the inner wall surface of the refrigerator compartment door 60 in the same manner as the other storage pockets 219. For this reason, the horizontal width of the lower storage pocket 220 is set to the same length as the horizontal width of the other storage pockets 219, and mounting grooves 223 are provided on both side walls to close the upper end and open the lower side.

  According to this structure, the lower storage pocket 220 can be attached to the refrigerating compartment door 60 by fitting the attachment protrusions (not shown) provided on the attachment rib 66 from above via the attachment grooves 223. In addition, with this structure, the lower storage pocket 220 can be replaced with another storage pocket, and therefore, it is possible to develop into a model that does not employ the water supply tank 400.

  Now, the lower storage pocket 220 according to this embodiment employs the notch portion 221, so that the first storage portion 426 having a large depth dimension and the second having a small depth dimension formed adjacent to the notch portion 221. And a storage portion 427. For this reason, the large first storage unit 426 can store large foods such as PET bottles and beer bottles, and the small second storage unit 427 can store small-sized foods that are frequently used.

  Further, the lower storage pocket 220 has a structure in which the back side is opened and the inner wall surface of the refrigerator compartment door 60 is the back wall. In addition, the lower storage pocket 220 is divided into two parts, and the upper part is formed of a transparent resin material, and the lower part is formed of an opaque resin material. This makes it easy to check the inside through the transparent portion even if food with a low height is stored while hiding dust accumulated on the bottom.

  Next, the upper drawer container 264 of the vegetable compartment 260 will be described with reference to FIGS. 9, 13, and 14. Here, FIG. 13 is a cross-sectional view showing the drawer structure of the upper drawer container. FIG. 14 is a comparison diagram of the upper drawer container and other drawer containers.

  First, in FIG. 9, in this embodiment, the housing storage space 261 of the vegetable compartment 260 is a plurality of sealed storage spaces composed of a plurality of drawer containers 263. Specifically, the housing storage space 261 is divided into three upper and lower parts, the upper stage is an upper drawer container 264 having an opening / closing lid 265, and the middle stage and the lower stage are a middle drawer container 267a composed of a container 268a whose upper part is opened, and a lower drawer. The container is 267b. These upper and lower three-stage drawer containers 263 can be moved in and out of the housing storage space 261 by moving in the front-rear direction via support rails (not shown) provided on the inner wall surfaces on both sides of the vegetable compartment 260.

  In this embodiment, in order to form a sealed storage space, the upper drawer container 264 is covered with the horizontal partition wall 4 in the stored state. The middle drawer container 267a and the lower drawer container 267b are provided below the upper drawer container 264 and include a hermetic lid 269 that covers the top of the container 268a.

  Further, in this embodiment, in order to ensure the storage capacity of the three drawer containers 263 as well, the lower lower drawer container 267 whose storage capacity is reduced due to the presence of the machine room 12 is extended to the distal end portion P2 of the housing 2. A space 270 is formed in front of the middle drawer container 267a and the upper drawer container 264, and is used as a door storage space 262 by using the space 270.

  In FIG. 13, the upper drawer container 264 according to this embodiment is arranged adjacent to the lower side of the horizontal partition wall 4 and behind the vegetable compartment 260 in order to secure a door storage space 262 in the front part thereof. Be placed. In addition, since the refrigerator 1 according to this embodiment includes the automatic ice making device 300, the freezer compartment door 50 is provided with an ice storage portion 320 and an outlet 350. For this reason, there is a thickness of the freezer compartment door 50, and the thickness of the refrigerator compartment door 60 is inevitably large. Therefore, in the upper drawer container 264, the length D10 from the door surface 9 of the refrigerator compartment door 60 located at the front part of the horizontal partition wall 4 to the tip of the upper drawer container 264 is an obstacle when taking in and out food. Therefore, there is a problem that food cannot be taken in and out from the upper drawer container 264 unless the upper drawer container 264 is pulled forward beyond the obstacle.

  However, when pulling the upper drawer container 264 forward, there is a problem that the upper drawer container 264 cannot be held unless it is wrapped to some extent with support rails (not shown) formed on both inner wall surfaces of the vegetable compartment 260. There is a limit to the solutions that can be pulled forward.

  Therefore, in this embodiment, an opening / closing lid 265 that is opened in accordance with the forward movement of the upper drawer container 264 and is housed below the horizontal partition wall 4 is employed on the front surface of the upper drawer container 264. . That is, in this embodiment, the storage container 271 whose upper side is opened and whose front side is cut obliquely, the opening / closing lid 265, and both side plates 273 that support the opening / closing lid 265 on both sides via the movable guide means 272, Consists of.

  The movable guide means 272 includes an upper support protrusion 274a and a lower support protrusion 274b formed on upper and lower ends on both sides of the opening / closing lid 265, a first support rail 275a and a second support rail 275b that support the two protrusions on both sides. Consists of The first support rail 275a is a groove formed rearward, supports the upper support protrusion 274a on 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, supports the lower support protrusion 274b on both sides, and moves the lower support protrusion 274b in a substantially vertical direction.

  As shown in FIG. 13A, the open / close lid 265 is held in a vertical posture so as to close the cut front portion of the storage container 271 in the storage state. On the other hand, as shown in FIG. 6C, when the upper drawer container 264 is pulled out, it is held in a horizontal posture between the horizontal partition wall 4 and the middle drawer container 267a.

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

  First, in the state in which the upper drawer container 264 shown in FIG. 5A is housed, the front surface of the upper drawer container 264 is the front portion of the storage container 271 having the handle portion 276 and the open / close lid in the vertical posture disposed on the top thereof. H.265. From this state, when the storage container 271 is pulled forward through the handle portion 274, the lower end of the vertical opening / closing lid 265 is pushed forward by the guide rails 277 at the upper part of the wall surface that are obliquely cut on both sides of the storage container 271. Is affected. However, the lower end portion of the opening / closing lid 265 is prevented from moving forward by the fitting of the lower support protrusion 274b and the second support rail 275b, and the stress moves the lower support protrusion 274b along the second support rail 275 upward. Move to.

  Accordingly, the upper support protrusion 274a moves rearward along the first support rail 275a. By this operation, the storage container 271 moves forward, whereby the lower end portion of the opening / closing lid 265 moves on the guide rail 277 and moves upward. As a result, as shown in FIG. The opening / closing lid 265 is stored in a horizontal posture between the horizontal partition wall 4 and the moved storage container 271.

  Further, when the storage container 271 is pushed in as shown in FIGS. (C) to (b), the opening / closing lid 265 supported by the guide rail 277 is also gradually lowered along the guide rail 277 by its own weight. (C) It becomes a figure and it returns to the original accommodation state as shown in (a) figure.

  FIG. 14 (b) shows a conventional technique including a storage container 271a whose upper part is open. According to this prior art, since the storage container 271a can only take in and out food from above, a food access space formed between the front upper end of the open portion of the storage container 271a and the lower end of the refrigerator compartment door 60. There is a problem that D20 becomes narrow.

  However, as shown in FIG. 6A, in this embodiment, the front wall surface of the storage container 271 is cut, so that the front upper end of the open portion of the storage container 271 and the lower end of the refrigerator compartment door 60 are shown. The food access space D20 formed between the portions can be made larger than that of the prior art shown in FIG. In addition, in this embodiment, the opening / closing lid 265 is concealed below the horizontal partition wall 4, so that there is no obstacle to taking in and out food.

  The refrigerator 1 having the above configuration is divided into a first storage unit 100 and a second storage unit 200 that are arranged in the width direction by a vertical partition wall 3 having a heat insulating material. , 200 is closed by doors 50, 60, 70 attached to both ends of the casing 2 in the width direction via hinges 5, and the door 50 closing the first storage unit 100 can be provided with water outside the cabinet. The dispenser portion 80 is provided, and the door 50 that closes the first storage portion is constituted by a single door 50 that closes the first storage portion 100 in the entire vertical direction. The second storage unit 200 is provided with a plurality of doors 60 and 70 arranged in the vertical direction. Therefore, when storing or taking out an object in the second storage unit 200, only the corresponding door 60 or 70 needs to be opened.

  By the way, the water normally provided in the dispenser part 80 is taken in from the exterior of the door 50, and specifically, the cold water supply piping which reaches the dispenser part 80 through the hinge part 5 from the exterior of the door 50 is provided. 7 is formed. However, since the hinge part 5 is a part used as the axis | shaft at the time of the door 50 opening and closing, piping to this part is not easy. In this respect, in the refrigerator 1 having the above-described configuration, the door 50 closes the first storage unit 100 in the entire vertical direction (that is, a single door). It can be kept in only one place that is necessary. Therefore, the structure of the refrigerator 1 can be simplified and the ease of manufacture and maintainability can be improved.

  In addition, the second storage unit 200 is provided with a water supply tank 400 for supplying water provided by the dispenser unit 80, and the water supply tank 400 is provided from the opened front side of the second storage unit 200. The water supply tank 400 is disposed at a vertical position corresponding to any one of the plurality of doors 60 and 70 in the second storage unit 200. Therefore, when the water supply tank 400 is handled, only one of the plurality of doors 60 and 70 arranged in the vertical direction needs to be opened. In addition, as operation | movement which handles the water supply tank 400, although various operation | movement targeting the water supply tank 400 can be considered, specifically, the operation | movement which takes out the water supply tank 400 as mentioned above, the water supply tank 400, etc. The operation | movement of replenishing water with arrange | positioning in the 2nd storage part 200 is mentioned.

  In addition, the water supply tank 400 is disposed at an intermediate portion in the vertical direction of the second storage unit 200. Here, since the middle part of the second storage unit 200 in the vertical direction corresponds to the height of a general user's hand, it is easy to reach out naturally. Therefore, forcing the user into an unreasonable posture when handling the water supply tank 400 is reduced.

  The water supply tank 400 is disposed in the vicinity of the vertical partition wall 3. For this reason, the water supply tank 400 will be arrange | positioned in the position on the opposite side to the hinge part 5 in the 2nd storage part 200. As shown in FIG. Therefore, as shown in FIG. 17, a space necessary for handling the water supply tank 400 can be ensured even if the door 60 or 70 that closes the second storage unit 200 is opened slightly without being fully opened. For example, the operation of opening the door 60 with the right hand and pulling out the empty water supply tank 400 with the left hand becomes possible.

  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, (a) the figure is a front view with the door open, and (b) the figure is a vertical partial sectional view of the freezer compartment. . Note that the same parts and arrows as those in the first embodiment are described with the same reference numerals, and redundant descriptions are omitted.

For example, as shown in FIG. 19, a structure in which an automatic ice making device 300 and an ice storage unit 320 are provided on the inner wall surface of the freezer compartment door 50 is also applicable.

  In this case, the ice making device pump 473 of the tank base 470 and the automatic ice making device 300 are connected to the ice making water supply pipe 6 via the hinge part 5 at the upper part of the freezer compartment door 50. Further, the ice-making water supply pipe 6 in the freezer compartment 100 is provided in the heat insulating material of the housing 2 so that the cold water in the ice-making water supply pipe 6 is not frozen.

  Since other structures are the same as those in the first embodiment, description thereof is omitted.

  Next, a third embodiment will be described with reference to FIGS. FIG. 20 is a cross-sectional perspective view of the refrigerator compartment 210 and the vegetable compartment 260. FIG. 21 is a perspective view of the vegetable compartment duct 280, the upper drawer container 264, the middle drawer container 267a, and the lower drawer container 267b of the vegetable compartment 260. FIG. 22 is an exploded perspective view of the vegetable compartment duct 280. FIG. 23 is a partial cross-sectional view of the refrigerator compartment and the vegetable compartment. 24 is a partially enlarged view of the vicinity of the vegetable compartment duct of FIG.

  FIG. 20 shows a state in which the vegetable compartment duct 280, the upper drawer container 264, the middle drawer container 267a, the lower drawer container 267b, and the like of the vegetable compartment 260 are removed. The rear wall 22d is provided with a vegetable compartment outlet 22d1 for blowing cold air to the vegetable compartment. Specifically, a plurality of vegetable compartment outlets 22d1 are provided in the vertical direction of the back wall 22d. Thereby, the temperature change in the vegetable compartment 260 can be suppressed, and so-called temperature unevenness in which the inside of the vegetable compartment 260 partially becomes high temperature or partially becomes low temperature can be suppressed.

  Further, as shown in FIG. 23, the vegetable compartment outlet 22d1 is provided at a height corresponding to each of the vegetable compartment duct 280, the upper drawer container 264, the middle drawer container 267a, and the lower drawer container 267b.

  The vertical partition wall 3 is provided with a vegetable room cold air return port 22d2. Specifically, the vegetable room cold air return port 22d2 is provided at a height where the middle drawer container 263 is provided.

That is, the vegetable room cold air return port 22d2 is provided at a height that is substantially the same as the height at which the cooling chamber 16 is provided, and that the cold air flows below the heat exchanger 13.

  Thus, the cold air blown into the vegetable compartment 260 from the vegetable compartment outlet 22d1 flows from the vegetable compartment cold air return port 22d2 to the cooling chamber 16, flows from the lower side to the upper side of the heat exchanger 13, exchanges heat, and again. This is a circulation structure that is blown out to the vegetable compartment 260.

  In the vegetable compartment 260, as shown in FIG. 21, an upper drawer container 264, a middle drawer container 267a, and a lower drawer container 267b are provided from the top. In addition, a vegetable compartment duct 280 is provided above the upper drawer container 264. Each of the drawer containers constitutes a closed space in which the movement of the gas is suppressed so that the cool air is not directly blown onto the stored item. As shown in FIGS. 20, 23 and 24, the vegetable compartment outlet 22d1 is provided at the vegetable compartment duct 280, below the upper drawer container 264, below the middle drawer container 267a, and behind the lower drawer container 267b, respectively. Yes. In other words, the vegetable compartment 260 is configured to be indirectly cooled, thereby preventing the stored product from drying and preventing the humidity of the storage space from being lowered.

  As shown in FIG. 22, the vegetable compartment duct 280 provided above the upper drawer container is, from below, the upper drawer container upper wall member 280a, the vegetable compartment duct heat insulating material 280b, the vegetable compartment duct frame 280c, and the thermal conductivity. This is a configuration having a panel 280d.

  The upper drawer container upper wall member 280a is a member constituting the upper wall portion of the upper drawer container 264. In the heat insulating material 280b for the vegetable compartment duct, as shown in FIG. 24, a cold air passage is provided so that the cold air blown out from the vegetable compartment outlet 22d1 flows from the rear to the front above the upper drawer container upper wall member 280a. Is formed. Specifically, as shown in FIG. 22 (d), a plurality of convex portions 280b1 are provided on the lower surface of the vegetable room duct heat insulating material 280b. And a cool air path is formed by combining the upper drawer | drawing-out container upper wall member 280a and the heat insulating material 280b for vegetable compartment ducts. That is, the upper surface of the upper drawer container upper wall member 280a forms one surface of the cold air passage, and the vegetable room duct heat insulating material 280b forms the upper surface and side surfaces of the cold air passage. The vegetable room duct frame 280c and the upper drawer container upper wall member 280a are engaged with each other by screws 280e, and the vegetable room duct heat insulating material 280b is provided in the space formed thereby.

  Thereby, it can suppress that cold air is sprayed directly on the stored thing of the upper drawer container 264, can indirectly cool, and can make cold air flow ahead from the back of a vegetable compartment.

  In addition, a thermally conductive panel 280d is provided above the vegetable room duct heat insulating material 280b via a vegetable room duct frame 280c. The vegetable room duct frame 280c and the upper drawer container upper wall member 280a are made of resin, whereas the thermally conductive panel 280d is made of metal (for example, aluminum). Further, as shown in FIG. 23, a return passage 22 through which the cold air blown into the refrigerator compartment 210 passes is provided in the horizontal partition wall 4 that partitions the vegetable compartment 260 and the refrigerator compartment 210. As shown in FIG. 24, the heat conductive panel 280 d is provided near the lower side of the horizontal partition wall 4. In other words, the heat conductive panel 280d is provided in the vicinity of the lower portion of the return passage 22. Thereby, the heat conductive panel 280d is cooled by the cold air passing through the return passage 22. Therefore, even when there is no cold supply in the vegetable compartment 260 during the defrosting operation of the heat exchanger 13, the temperature change in the vegetable compartment 260 can be suppressed by the radiant heat of the low-temperature heat conductive panel 280d. In addition, the load applied to the stored item due to the temperature change can be reduced.

  Further, even when no cold air is supplied into the refrigerator compartment 210 during the defrosting operation of the heat exchanger 13, the inside of the refrigerator compartment 210 is radiated by the radiation heat of the radiation plate 222 and the heat conductive panel 280d provided on the back of the refrigerator compartment. It is possible to reduce the load applied to the stored item due to the temperature change.

  Since other structures are the same as those in the first embodiment, description thereof is omitted.

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

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

  In general, since the temperature of the freezer compartment 100 is lower than that of the refrigerator compartment 210, the machine room 12 that becomes high temperature is provided behind the refrigerator compartment 210, and the cooling room 16 is provided behind the refrigerator compartment 100, The temperature influence from the machine room 12 is reduced. Thereby, cooling efficiency can be improved. That is, energy required for cooling can be reduced.

  In addition, in this Embodiment, although the freezer compartment 100 and the refrigerator compartment 210 are divided into right and left with the vertical partition wall 3, the structure which further provides a vegetable compartment below the refrigerator compartment 210 may be sufficient. In this case, the machine room 12 is provided behind and below the vegetable room.

  In the present embodiment, the machine room 12 is provided behind and below the refrigerator compartment 210, but the machine room 12 may be provided behind and above the refrigerator compartment 210. As a result, it is possible to effectively use the upper rear portion of the refrigerator compartment 210, which is a space that is difficult to reach, and to improve usability.

  Next, the cold air flow in the freezer compartment 100 will be described. Above the cooling chamber 16, a freezer compartment back surface passage 18 that communicates with the entire rear portion of the freezer compartment 100 is provided.
