A room 131 is arranged, and in the right section, a vegetable room 133 having a pull-out door 132 and a freezing room 135 having a pull-out door 134 are arranged in order from the top.

  Here, the second partition wall 127 is disposed on substantially the same plane as the first partition wall 106 of the upper section in the vertical direction. That is, the first partition wall 106 and the second partition wall 127 are arranged in a positional relationship such that they are continuous in a straight line in the vertical direction when viewed from the front of the refrigerator body 101, and the drawer doors 109, 128 in the left compartment are arranged. 130 is configured with the same width.

  Next, the drawer structure of the drawer-type door 109 will be described with reference to FIGS.

  The pull-out door 109 is supported by an upper support rail 140 and a lower support rail 141 provided on the upper left side of the left region 107, and no support rail is provided on the right side surface of the pull-out door 109.

  More specifically, an upper frame 142 fixed as a frame body above the back surface of the drawer-type door 109 and a lower frame 143 fixed below the upper support rail 140 and the upper frame 142 are connected to the lower support rail 141. The lower frame 143 is engaged and fixed.

  Further, the upper support rail 140 includes a fixed rail 144, a moving rail 145, and an intermediate rail 146, and the sliding of the fixed rail 144 and the intermediate rail 146, and the moving rail 145 and the intermediate rail 146, respectively, via a plurality of bearings 147. Works. Then, the fixed rail 144, the moving rail 145, and the intermediate rail 146 are fixed in advance in a state in which the fixed rail 144 is assembled, and then the upper frame 142 and the moving rail 145 are connected and fixed by screws. The lower support rail 141 has the same structure and connection specifications as the upper support rail 140.

  In the present embodiment, the bottom surface of the drawer-type door 109 is further provided with a bottom surface support rail 148 as a drawer mechanism. The bottom support rail 148 has the same structure as the upper support rail 140, and the bottom support rail 148 is installed at least on the side far from the center in the lateral direction of the bottom with respect to the drawer mechanism provided on one of the left and right side surfaces. .

  The lower support rail 141 and the bottom support rail 148 are engaged and fixed to the left and right frames of the lower frame 143, respectively.

  The drawer type door 109 has a vertically long shape having a height dimension larger than a width dimension. Further, any or all of the upper support rail 140, the lower support rail 141, and the bottom surface support rail 148 may be installed so as to have a slight upward inclination toward the front of the refrigerator 101 main body.

  Further, as shown in FIG. 7, an L-shaped cover 149 may be provided on the bottom surface in the cabinet so as to cover the upper part of the bottom surface support rail 148.

  In addition, when the bottom support rail 148 is not used, it is desirable that the upper support rail 140 and the lower support rail 141 are installed at substantially equal positions in the vertical direction of the drawer door 109 from the end surface.

  Moreover, as shown in FIG. 8, you may provide the drawing-in apparatus 150 comprised with the spring etc. in the store | warehouse | chamber interior back side edge part of a support rail. Further, a damper mechanism (not shown) may be provided integrally with the retracting device 150.

  Next, the effect | action is demonstrated about the refrigerator comprised as mentioned above.

  First, due to the presence of the first partition wall 106, in the left region 107, one side of a rail mechanism that allows the storage container 113 to slide back and forth in accordance with the opening / closing operation of the pull-out door 109 is fixed to the side surface. On the other hand, the pull-out door 109 can be stably slidably supported by receiving a load in a balanced manner in a pair with the rail mechanism fixed to the side wall surface of the inner box 115 of the upper section.

  On the other hand, due to the presence of the first partition wall 106, the right side region 108 is a shelf holder in which one side of the shelf 114 is provided on the side wall surface of the first partition wall 106 and the other side is the side wall surface of the inner box 115. It is possible to receive a load in a well-balanced manner with a shelf holder provided on the, and to stably fix and support it. In addition, a rail mechanism on one side of the low temperature chamber 116 can be provided at the same time to provide a stable sliding structure for the storage container 117.

  When both the left region 107 and the right region 108 form a chamber using a hinged rotary door, a shelf for storing the storage items is provided across both regions, and both ends of the shelf are connected to both sides of the inner box. The wall shelf 114 may be supported by a wall surface, but when the area on one side is a room using the pull-out door 109 as in this embodiment, The wall surface of the inner box that supports the end on one side cannot be used, and a simple and inexpensive shelf support structure cannot be realized unless a structure that supports this is provided separately.

  Therefore, the first partition wall 106 is provided in the upper section 104 to support the shelf 114 in the right area 108 and at the same time has a function of slidingly supporting the storage container 113 provided in the pull-out door 109 in the left area 107. It is reasonable for the support structure to be stable and stable in strength.

  On the other hand, however, partitioning by simply providing a partition wall in the partition, as described in the above-mentioned prior art, gives a user and a purchaser a particularly visual narrowness. Although it was a negative factor, according to the present embodiment, the space 112 is provided in front of the first partition wall 106 and the left region 107 and the right region 108 are visually communicated with each other. In particular, when the hinged door 110 is opened and the inside of the right area 108 is looked into, the eyes of the user and the purchaser are open to the front, so the first partition wall 106 continues to the back side. Even if it is, it can feel a sense of spaciousness without feeling a feeling of pressure or blockage.

  In the right region, the front end surfaces of the plurality of shelves 114 and the low temperature chamber 116 are aligned with the front end surface of the first partition wall 106 so that the space 112 is substantially Since the depth of the door has a space to the front end surface of the indoor storage unit such as the shelf 114 and the low temperature chamber 116, the user and the purchaser have a sense of unity and feel refreshed. It is even more spacious and easy to use.

  Further, in the present embodiment, as a sealing structure body for the joint portion of the hinged door 110 and the pull-out door 109, the rotating partition 118 provided on the reverse side of the hinged door 110 on the reverse side is used. A seal structure is used, and the depth interval of the space 112 is set so that the rotation region of the rotating partition 118 is included within at least the space 112 formed in front of the first partition wall 106. Therefore, even if the rotating partition 118 rotates, it does not interfere with the first partition wall 106, and the door can be opened and closed without any hindrance, and the sealing seal at the joint between the hinged door 110 and the pull-out door 109 can be provided. It can be done.

  That is, in the present embodiment, the front of the first partition wall 106 is provided in order to provide a user and a purchaser with a sense of spaciousness in the room while providing a stable support structure for each storage structure of the upper section 104. A predetermined space 112 is provided in the door, and by utilizing this space 112, a door with a rotating partition 118 capable of hermetically sealing the hinged door 110 and the pull-out door 109 without using the front end face of the first partition wall 106. A seal structure can be realized at the same time.

  In addition, the visual effect mentioned above opens the hinged door 110 especially in the upper section 104 which a user will face and use in front of the eyes like this embodiment. Although it is remarkable for the room such as the right region 108 used while looking around the room, a certain effect can be expected even when the same configuration is adopted for the lower section 105.

  Next, the first partition wall 106 and the second partition wall 127 are arranged in a positional relationship such that they are continuous in a straight line in the vertical direction when viewed from the front of the refrigerator body 101, and the pull-out door 109 in the left compartment, 128 and 130 can be configured with the same width, and the design of the external appearance product of the refrigerator can be improved. Moreover, since it is comprised so that it may cross | intersect the partition wall 103 arrange | positioned on the straight line in the left-right direction in order to partition the refrigerator main body 101 up and down, the heat insulation box 102 increases the rigidity as a housing | casing, As a result, the rail mechanism that slidably supports the storage container 113 on the side surface on the left region side of the first partition wall 106 is fixed, and the storage shelf 114 is supported on the side surface on the right region side. The strength of the can be ensured.

  Next, regarding the cooling configuration in the upper section 104, the cold air supplied from the cold air outlet 123 in the back of the left region 107 is forward from the rear because the cold air outlet is the front space 112. The stored items or the like stored in the storage container 113 in the region are circulated while being cooled, and therefore the left region 107 is cooled substantially as a whole.

  The temperature distribution in the refrigerator is usually a temperature distribution in which the temperature is lower at the back of the interior where the cooling source such as the cooler 119 and the cold air duct is installed, and the temperature increases toward the front. In particular, the foremost part near the door is most difficult to receive the convection of the cold air, and particularly when the storage part such as a door shelf is provided in the vicinity of the front part, it is not easy to promote the cooling of the storage part. On the other hand, in the present embodiment, since the cooling air passage always passes through the space 112 in the front part of the region, it is easy to supply cold air to each storage part in the vicinity of the foremost part. The temperature distribution can be made uniform.

  Next, the cold air passes through the front end portion of the first partition wall 106 from the front space 112, flows into the right region 108, and is sucked into the cold air inlet 125 provided below the back portion. The items stored on the shelf 113 are cooled moderately with the inside facing from the front to the rear.

  That is, here, the space 112 also functions as a cold air circulation section between the left region 107 and the right region 108.

  On the other hand, the cool air supplied from the cool air discharge port 124 in the right region merges with the cool air flowing in from the left region 107 while cooling the stored items and the like stored on the shelf 114 from the rear to the front. Since the air is sucked into 125, the cooling air for cooling is supplied from the front-rear direction to the right region 108, and the entire region is uniformly cooled. Especially when the inner volume of the right area 108 having the hinged door is larger than the inner volume of the left area 107 having the pull-out door 109 as in the present embodiment, it is difficult to achieve uniform temperature overall. According to the cooling method in which cold air is supplied from both the front and rear directions, the temperature distribution width in the region can be suppressed as small as possible, and the cooling effect is large.

  In addition, even though the cold air inlet 125 is shared, the cold air outlets 123 and 124 have their own dedicated ones, so the air path is configured so that the two regions are connected in parallel, and the cooling design of each region is free. Therefore, it is easy to design the temperature in the region and make the temperature uniform.

  In this way, the presence of the first partition wall 106 allows cooling air to flow between the left and right regions through the space 112, so that in one embodiment, that is, in the present embodiment, the cold air suction port of the left region 107 and the cooling air intake port. There is no need to provide a subsequent cool air intake air passage, and a rational cooling air passage configuration in which the return path to the cooler 119 is simplified is possible.

In particular, in the case where it is supported on one side of the drawer type door 109 as in the present embodiment, there is a remarkable effect, and the drawer type door 109 becomes non-parallel, and there are problems such as deterioration in the appearance quality and cold air leakage in the storage room. Can also be reasonably addressed. Further, by providing the intermediate rail 146, the front drawer allowance (opening dimension to the front) of the drawer-type door 109 can be set large, so that food can be easily taken in and out and the usability is further improved.

  Further, any one or all of the upper support rail 140, the lower support rail 141, and the bottom support rail 148 are installed so as to be inclined slightly upward toward the front of the refrigerator 101 main body, so that the drawer type door can be operated with a light force. 109 can be closed securely.

  In the present embodiment, each support rail has been described as consisting of a fixed rail 144, a moving rail 145, and an intermediate rail 146. However, a frame connected to a drawer-type door, a roller fixed to the frame, A configuration provided with rails formed on the walls constituting the interior may be used. In this case, it is possible to simplify the assembling work by separating the slidability by the roller and the rail and the frame. In addition, it is possible to reduce the cost by using a simple drawing mechanism.

  Further, in the present embodiment, the bottom support rail 148 as a drawer mechanism is further provided on the bottom surface of the drawer-type door 109. However, the upper support rail 140 and the lower support provided on the upper left side of the left region 107 are described. It is good also as a structure supported only by the rail 141. FIG. At this time, the upper support rail 140 and the lower support rail 141 are installed at positions substantially equal to the end surface in the vertical direction of the drawer door 109 so that the displacement amount is equal to the lateral force of the drawer door 109. Therefore, the operability of the drawer type door 109 can be improved.

  The bottom support rail 148 provided as a drawer mechanism on the bottom surface of the drawer-type door 109 has been described as comprising the fixed rail 144, the moving rail 145, and the intermediate rail 146. However, the lower frame 143 is provided with a roller, The structure which receives the said roller by an inner bottom face may be sufficient. In this case, the cost can be reduced with a simple structure.

  Moreover, the reliability at the time of closing of the drawer | drawing-out type door 109 can be improved by providing the drawing-in apparatus 150 comprised with the spring etc. in the inner-end side edge part of a support rail. Further, by providing a damper mechanism integrally with the pull-in device 150, the impact when the drawer-type door 109 is closed can be alleviated, and tall foods stored inside are less likely to fall down, improving usability.
