  Hereinafter, embodiments will be described in detail with reference to the drawings.

  As shown in FIG. 1 to FIG. 3, the refrigerator 1 of the embodiment has a refrigerator compartment 2 that is closed by two doors 11 and 12 that are opened and closed in a double door manner, and a vegetable compartment 3 below the refrigerator half 1. An ice making chamber 4 and an upper freezing chamber 5 as an upper storage chamber are provided below, and a main freezing chamber 6 as a lower storage chamber is further provided below the ice making chamber 4 and an upper storage chamber. The vegetable compartment 3 has a vegetable case 3A, the ice making chamber 4 has an ice box 4A, the upper freezer compartment 5 has an upper freezer compartment case 5A, and the main freezer compartment 6 has a main freezer compartment case 6A as a lower case. The sub freezing case 6B for quick freezing which opens on the box shape as a sub case which slides on it is accommodated in a drawer type. Doors 3B, 4B, 5B, and 6C are attached to the vegetable case 3A, ice box 4A, upper freezer compartment case 5A, and main freezer compartment case 6A, respectively.

  In the front opening of the refrigerator compartment 2, the opening is divided in the width direction, and is a left-handed left (toward left) that is pivotally supported by hinges 21 and 22 provided on both left and right sides of the refrigerator main body. A door 11 and a right door 12 (to the right) are provided and are configured to be closed by both doors 11 and 12. Gaskets 141 and 142 each provided with a magnet (not shown) are attached to the peripheral edges of the back surfaces of both doors 11 and 12, respectively. 1 and 2, a vertical partition member 15 having a length extending substantially over the entire length in the vertical direction is pivotally supported along with the gasket 141 on the back surface of the free end of the left door 11.

  When both doors 11 and 12 are opened and closed simultaneously, or when one of the doors 11 and 12 is opened and closed, the operation of sealing the refrigerator compartment 2 by the vertical partition member 15 and the gaskets 141 and 142 is as follows. When the left door 11 is closed from the open state in which the vertical partition member 15 is in a posture substantially perpendicular to the door surface, the vertical partition member 15 is rotated to a posture substantially parallel to the door surface by a spring action. The left half of the front side of the member 15 faces the back side of the free end of the left door 11, and the right half of the front side of the vertical partition member 15 faces the back of the free end of the right door 12. And the magnet inserted in the inside of the gaskets 141 and 142 adsorb | sucks to the iron plate of the surface of the vertical partition member 15, the gaskets 141 and 142 closely_contact | adhere to the surface of the vertical partition member 15, and the refrigerator compartment 2 is sealed.

  As shown in FIG. 3, the outer box of the refrigerator 1 is composed of a heat insulating panel filled with urethane foam. However, heat insulation is improved by disposing vacuum heat insulating panels 30 on both side surfaces of the main body. The panel is made thinner and the outer volume is made compact while ensuring a large inner volume. Further, a heat radiating pipe 31 is circulated in the heat insulating panels on the side surface, top surface, and front surface of the refrigerator 1 to prevent dew condensation due to the heat dissipation of the cooler and the contact of each part with the outside air in a low temperature state.

  The structure of the storage space 40 will be described with reference to FIGS. As detailed in the cross-sectional views of FIGS. 4 to 6, the space below the vegetable compartment 3 in the refrigerator 1 is partitioned by a heat insulating partition plate 41 to form a storage space 40. The storage space 40 is partitioned by the partition member 42 into the upper freezer compartment 5 and the main freezer compartment 6 therebelow. The heat radiation pipe 43 described above is passed through the inside of the front surface of the partition member 42, and by heating the partition member 42, it is possible to suppress a certain amount of outside air coming into contact with the surface and causing condensation.

  As shown in detail in FIGS. 5 and 6, the ice making chamber 4 is provided with an ice tray 401 on the upper side, and an ice box 4 </ b> A for storing ice made on the ice tray 401 on the lower side. It is installed. An ice making room door 4B is attached to the ice box 4A. A reinforcing plate 402 is provided below the ice box 4A, and supports the ice box 4A so that it can slide back and forth. The reinforcing plate 402 has a length up to the middle of the depth of the ice making chamber 4, and an opening 403 is formed on the far side.

  In the upper freezer compartment 5, an upper freezer compartment case 5 </ b> A with the upper freezer compartment door 5 </ b> B attached to the front surface is accommodated in a drawer type. Also in the main freezer compartment 6, a main freezer compartment case 6A with a main freezer compartment door 6C attached to the front surface is accommodated in a drawer type. A cold air inlet 6Aa is formed in the rear portion of the main freezer compartment case 6A by a notch. A sub freezing case 6B for quick freezing is slidably provided on the upper side of the main freezer compartment case 6A.

  A cold air duct 45 in which a refrigeration cooler 44 is installed is formed at the back of the storage space 40. At the lower end of the cold air duct 45, a cold air inlet 45A that opens to the main freezer compartment 6 is formed. The inside cold air is taken into the cold air duct 45 from the cold air inlet 45A, passed through the refrigerating cooler 44 from the bottom to the top to be cooled to the freezing temperature, and the cooled free air from the back to the upper freezing chamber 5 is cooled. At the same time, the cool air is circulated through the cool air outlets 46 and 47 formed at the positions of the upper part and the middle part of the main freezer compartment 6, respectively. This forced circulation of cold air is performed by a cold air fan (not shown) installed in the upper part of the cold air duct 45.

  A horizontal rear portion of the partition member 42 that partitions the storage space 40 up and down is a small space 48 that divides the upper freezer compartment 5 and the main freezer compartment 6, and a cool air blowing duct 49 is installed at the position of the small space 48. It is. As shown in detail in the external views of FIGS. 7 and 8, the cold air blowing duct 49 includes a flat cylindrical cold air guide duct portion 49A having a wide rear portion and a narrow front portion, and a periphery of the duct portion 49A. It is comprised by the cover part 49B integrated with the surface. Further, in the lid portion 49B, a communication portion 49C is formed in a portion (the left rear portion in FIG. 7) located below the rear portion of the ice box 4A, and the hole edge on the front side of the communication portion 49C A plurality of inclined ribs 49D, which become lower as they approach the communication portion 49C, are formed as guide portions. Further, in the cool air guide duct portion 49A, an inclined portion 49E that becomes lower as it approaches the communication portion 49C is expanded at a portion corresponding to the hole edge on the side of the communication portion 49C described above than the other portions of the duct portion 49A. It is formed as a protruding bulge.

  In the case of the present embodiment, the communication portion 49C is formed by cutting out a part of the lid portion 49B of the cool air blowing duct 49, but a hole is formed in the corresponding portion of the lid portion 49B. The hole can be used as the communication portion 49C.

  A cold air outlet 50 is formed on the lower surface of the front end portion of the cold air guide duct portion 49A in the cold air outlet duct 49 so as to open downward. The rear end opening 51 of the cold air guide duct portion 49A is wide, and at the same time, is also wide. The rear end opening 51 is fitted and fixed around the cold air outlet 46 on the upper side of the cold air duct 45. As indicated by a dotted line in FIG. 7, reinforcing ribs 52 are provided in the front-rear direction in the internal space of the cool air guide duct portion 49A.

  The cold air guide duct portion 49 </ b> A in the cold air blowing duct 49 has such a length that the cold air outlet 50 is located at an intermediate position in the front-rear direction of the small space 48. As a result, the cold air blown forward from the cold air outlet 46 of the cold air duct 45 is blown into the cold air guide duct portion 49A of the cold air outlet duct 49, and further proceeds forward in the cold air guide duct portion 49A. The food is blown downward from the cold air outlet 50 on the lower surface, and the food stored in the upper sub freezing case 6B in the main freezer compartment 6 is quickly frozen by the blown cold air. In particular, since the rear end is wide, a large amount of cool air from the cool air duct 45 can be taken in, and the cool air is collected at the cool air outlet 50 located at the center of the front end of the duct 49A to be blown out to the center of the auxiliary refrigeration case 6B. Can do. Then, as depicted by a chain line in FIG. 4, by setting the aluminum plate 54 at the bottom of the auxiliary refrigeration case 6B, the cold air is diffused throughout the space in the auxiliary refrigeration case 6B through the aluminum plate 54, and the case 6B. The inside can be frozen and cooled evenly.

  The main refrigeration case 6A is cooled by the cold air blown out from the cold air duct 45 through the cold air outlet 47 in the middle of the back portion. Since the auxiliary freezing case 6B is covered with the lid portion 49B of the cold air blowing duct 49, the upper freezing room 5 and the main freezing room 6 can be partitioned, and the auxiliary freezing case 6B can be substantially sealed. Can be quickly frozen and cooled. Further, since the auxiliary refrigeration case 6B has a smaller storage capacity than the main refrigeration case 6A and is provided with the aluminum plate 54, it can be refrigerated and cooled more rapidly. Furthermore, since the height is the same as that of the lower surface of the partition member 42, it is possible to prevent food frozen when being pulled out from being caught by the partition member 42 and being unable to be pulled out. Further, the portion of the main refrigeration case 6A can be cooled effectively because the cold air that has cooled the upper freezing chamber 55 also descends through the side of the sub refrigeration case 6B and cools.

  In this way, by installing the cool air blowing duct 49 in the small space 48 in the horizontal rear portion of the partition member 42, it is possible to use a space that is not originally provided for food storage for the installation of the cold air blowing duct 49. It is possible to guide the cold air to a predetermined blowing position without reducing the food storage space, and there is an advantage that the main freezer compartment can be cooled uniformly.

  At the same time, since the cold air is blown downward from the cold air outlet 50 on the lower surface of the front end of the cold air guide duct portion 49A at the front and rear intermediate positions of the small space 48, it can be cooled uniformly from the upper center of the main freezer compartment 6. Furthermore, since the aluminum plate 54 is placed, it is possible to transfer cold air from the center of the plate to the outside. In addition, cold air does not directly hit the partition member 42 located in front of the small space 48 from behind, and for this reason, it is effective that the partition member 42 is excessively cooled and dew condensation is caused by outside air that contacts the front side. Can be suppressed. In the case of the present embodiment, since the heat radiating pipe 43 is passed through the inside of the partition member 42, it is possible to reliably prevent condensation on the partition member 42, coupled with the heat generated by the heat radiating pipe 43.

  Furthermore, since the cold air is blown out into the main freezer compartment 6 through the cold air duct 45 and the cold air outlet 50 and the lower cold air outlet 47 through the cold air outlet 45 and the lower cold air outlet 47. The portion of the freezing case 6B and the portion of the main freezing case 6A below it can be effectively cooled simultaneously in parallel. In particular, the sub refrigeration case 6B can be rapidly refrigerated and cooled by blowing out the cold air from the upper cold air outlet 50, and the chilled air can also be sent to the main refrigeration case 6A located below the sub refrigeration case 6B. Can accommodate food separately for different purposes, such as being accommodated in the sub-frozen case 6B. At the same time, the cold air outlet 47 is arranged so that the cold air is blown out from the lower rear side to the front side of the sub refrigeration case 6B. Therefore, the bottom surface of the sub refrigeration case 6B is also cooled by the cold air blown out from the cold air outlet 47. The cooling performance by the aluminum plate 54 can be further improved, and at the same time, the cold air inlet 6Aa is provided by notching the rear of the main refrigeration case 6A so that the cold air enters the main refrigeration case 6A. Cold air can be reused in the main refrigeration case 6A. Further, the rear end of the cold air inlet 6Aa extends rearward, is located below the cold air duct 45, and is disposed along the upper end of the cold air inlet 45A for sucking the cold air in the cabinet. It is possible to prevent cold air from the blowout port 47 from being directly sucked into the cold air suction port 45A and being used as a shortcut, and to effectively use the cold air for cooling the freezer compartment.

  Further, a cold air blowing duct 49 is installed at the position of the small space 48, and the auxiliary refrigeration case 6B is covered with a lid portion 49B of the cold air blowing duct 49. The cold air blown out from the back portion does not enter the upper freezing case 6B of the main freezer compartment 6, but passes through both sides thereof downward and flows into the main freezing case 6A. The part can also be cooled from the surroundings.

  Further, in the lid portion 49B of the cool air blowing duct 49, a communication portion 49C is provided at a position below the rear portion of the ice box 4A, and the inclined rib 49D and the inclined portion 49E that become lower as the communication portion 49C is approached are connected to the communication portion 49C. Due to the formation at the hole edge, there are the following effects.

  The ice made in the ice tray 401 is automatically stored in the ice box 4A. When the communication portion 49C, the inclined rib 49D, and the inclined portion 49E are not formed, if the ice stored in the ice box 4A is full, the ice that is further made and dropped from the ice tray 401 is removed from the ice box 4A. It may overflow and remain caught in the gap between the ice box 4A and the ice making chamber 4. In addition, when the ice box 4A is almost full, the user pulls out the ice box 4A to take out the ice, and then pushes the ice box 4A into the ice making chamber 4. The ice in 4A may overflow and remain in the gap between the ice box 4A and the ice making chamber 4. In such a case, it may be impossible to smoothly pull out and push in the ice box 4A.

  On the other hand, in the case of the present embodiment, since the communication part 49C is formed, when the ice stored in the ice box 4A is full, the ice that is further made and dropped from the ice tray 401 is Even if it overflows from the ice box 4A, it falls to the part of the communication part 49C through the opening 403 at the rear of the reinforcing plate 43, and further reaches the lower storage chamber below it through the communication part 49C. There is no.

  In addition, since the inclined rib 49D and the inclined portion 49E are formed adjacent to the hole edge, the ice falling around the communication portion 49C can be communicated with the inclined rib 49D and the inclined portion 49E as a slide guide. It guides so that it may fall into the part 49C, and it will reach the lower storage room below it through the communication part 49C, and it will not get caught on the way.

  Further, the main freezer compartment 6 which is a storage room is divided into upper and lower parts, a sub freezer case 6B is installed on the upper side, a main freezer case 6A is installed on the lower side, and the communication part 49C is connected to the upper sub freezer case 6B. Since it forms so that it may communicate, the ice which falls through the communicating part 49C from the ice making chamber 40 can be stopped by the upper sub freezing case 6B, and there is an advantage that it is easy to remove the falling ice.

  For this reason, according to the present embodiment, the ice that is made in the ice making chamber 4 and stored is not caught in the gap between the ice box 4A and the ice making chamber 4, and the ice box 4A can be pulled out and pushed in smoothly. For this reason, the ice box 4A is not disturbed by the overflowing ice and caught in the middle of the ice making chamber 4, so that the ice making chamber door 4B cannot be completely closed. For this reason, ice does not melt without the user's knowledge and contributes to energy saving.
