The horizontal cross-sectional shape of the relief portion 28a3 is an arc connecting the corner portion side end portion 28a4 of the front surface portion 28a1 of the left frame piece 28a and the corner portion side end portion 28a5 of the side surface portion 28a2. The farthest portion P of the relief portion 28a3 of the left frame piece 28a exists in a circle Y having a radius (A + t) with the rotation axis center Q as the center.

  FIG. 11 is a horizontal cross-sectional view of the vicinity of the relief portion 28a3 when a wave shape is provided as the relief portion 28a3 of the corner portion 28a6 of the left door frame frame 28. The horizontal cross-sectional shape of the relief portion 28a3 is a wave shape connecting the corner side end portion 28a4 of the front surface portion 28a1 of the left frame piece 28a and the corner side end portion 28a5 of the side surface portion 28a2. The wave shape is a shape in which a plurality of arcs are connected on the wave. The farthest portion P of the relief portion 28a3 of the left frame piece 28a exists in a circle Y having a radius (A + t) with the rotation axis center Q as the center.

  In any of the chamfered shape, the arc shape, and the wave shape, the escape portion 28a3 is formed so that the farthest portion P of the escape portion 28a3 exists in the circle Y. Can open up to. The same can be said for the right refrigerator compartment door 4.

  Next, the configuration of the operation panel 5 will be described. FIG. 12 is a cross-sectional view of the operation panel 5. In FIG. 12, the operation panel 5 includes a film 32 on which characters and illustrations are printed, an operation front panel 33 integrated with the film 32, a substrate 36, an LED 39 for illuminating the characters and illustrations printed on the film, and a light guide. An optical plate 35, an elect box 34 for preventing light leakage, and a substrate holder 37 are provided. A boss shape for positioning the elect box 34 and the substrate 36 is attached to the back surface of the operation front panel 33. Moreover, you may have a light guide part with the same function as the light guide plate 35. The operation panel 5 is formed by integrating the film 32 printed with characters and illustrations and the operation front panel 33, positioning the elect box 34 on the back side thereof, inserting the light guide plate 35 into the hole of the elect box 34, 36, and finally it is fixed by the substrate holder 37. Since the operation panel 5 is a capacitance type, the substrate presser 37 is necessary for bringing the electrode 40 on the substrate into close contact with the pressing portion. Therefore, as shown in FIG. 12, the substrate 36 is on the back side of the elect box 34, and the electrode 40 is arranged on the substrate so as to be directly below the pressing portion. A certain LED 39 illuminates from a portion other than directly below. An operation panel receiver 38 is provided as a member for receiving the operation panel 5. The operation panel receiver 38 is disposed between the refrigerator compartment left door vacuum heat insulating material 16 and the refrigerator compartment left door 3. After the operation panel receiver 38 is temporarily fixed to the back side of the refrigerator compartment left door 3 before foaming, aluminum is used. Affixed with tape. Then, after foaming, the operation panel 5 is fitted into the operation panel receiver 38, whereby the operation panel 5 is arranged on the left door 3 of the refrigerator compartment. Note that the configuration of the operation panel 5 is not limited to this, and for example, a configuration using the transparent electrode 41 may be used.

  A configuration using the transparent electrode 41 in the operation panel 5 will be described below. FIG. 13 is a cross-sectional view of the operation panel 5 using the transparent electrode 41. The configuration of the operation panel 5 using the transparent electrode 41 is almost the same as the configuration shown in FIG. 12, but the positions of the electrodes are different. As shown in FIG. 13, since the transparent electrode 41 exists alone, it can be arranged on the operation front panel 33 side. Accordingly, since the LED 39 on the substrate can be illuminated from directly below, it is possible to evenly illuminate the display portion such as characters and illustrations. Further, since the position of the electrode is not on the substrate and is integrated with the operation front panel 33 side, the substrate holding member 37 for closely contacting the electrode is not necessary. Therefore, in the configuration of the operation panel 5 using the transparent electrode 41, the transparent electrode 41 on which characters, illustrations, and the like are printed is attached to the front portion of the elect box 34, and the light guide plate 35 and the substrate 36 are attached to the rear surface of the elect box 34. After placing, it is fixed. In the case of the operation panel 5 using the transparent electrode 41, the operation panel receiver 38 exists as a member that receives the operation panel 5. The operation panel receiver 38 is similarly disposed between the refrigerator compartment left door vacuum heat insulating material 16 and the refrigerator compartment left door 3, and after temporarily fixing the operation panel receiver 38 to the back side of the refrigerator compartment left door 3 before foaming, Affixed with aluminum tape. Then, after foaming, the operation panel 5 is fitted into the operation panel receiver 38, whereby the operation panel 5 is arranged on the left door 3 of the refrigerator compartment. As a method for fitting the operation panel 5 into the operation panel receiver 38, for example, there is a method of inserting from the side of the refrigerator door left door 3.

  FIG. 14 is a perspective view of the elect box. For example, when a guide is provided on the operation panel receiver 38 so that the operation panel 5 can be easily inserted, the operation panel receiver 38 is deformed at the time of foaming, causing a problem that the operation panel 5 is difficult to insert or cannot be inserted. By providing the spring shape 42 on the upper surface of the elect box 34, it is possible to cope with deformation of the operation panel receiver 38. Further, by providing the ribs 43 on the side surface of the elect box 34 on the insertion port side of the operation panel 5, the left and right positions after insertion can be fixed. Further, by hooking a part of the elect box 34 having the ribs 43 to the right frame piece 28b, it is possible to easily replace the board at the time of service, so that serviceability can be improved. However, the installation method of the operation panel 5 is not limited to this, For example, the method of fitting from the front surface of the refrigerator compartment left door 3 may be used. The arrangement of the operation panel 5 is not limited to the left side of the refrigerator compartment 3. The operation panel 5 may be disposed in the refrigerator compartment 2, for example.

  The operation panel 5 is a thin panel type operation panel, and even if the operation panel is installed in front of the left refrigerator compartment door 3, the thickness of the left refrigerator compartment door 3 hardly increases. In particular, if the operation panel 5 is installed in front of the left refrigeration room door 3 so that only the display surface on which characters, illustrations, etc. indicating the operation contents are printed is exposed, the thickness of the left refrigeration room door 3 does not increase. . The display surface is the upper surface of the film 32 in the operation panel 5 of FIG. 12, and the upper surface of the operation front panel 33 in the operation panel 5 of FIG. Even if the operation panel 5 is provided in front of the left refrigerator compartment door 3, the left refrigerator compartment door 3 can be opened 90 or more, and the operation relating to the refrigerator 1 can be performed by a simple operation of touching the operation panel 5. . The contents that can be operated on the operation panel 5 include, for example, switching of the energy saving mode, start / stop of rapid ice making, and switching of the switching chamber 6 to be a freezer compartment or a soft freezer compartment.

  FIG. 15 is an exploded perspective view of the door closing device 44 and the lower hinge 45. FIG. 16A is a plan view of the door closing device 44. FIG.16 (b) is a longitudinal cross-sectional view in the BB line of Fig.16 (a). FIG. 17A is a side view of the door closing device 44. FIG. 17B is a cross-sectional view taken along line AA in FIG. The lower hinge 45 has a vertical piece 45b provided with a plurality of screw insertion holes 45d and a horizontal piece 45 formed integrally therewith, and has a substantially L-shaped shape. The lower hinge 45 is fixed to the lower part of the refrigerator compartment 2 by fixing the vertical piece 45b to the lower part of the refrigerator compartment 2 with screws. A receiving portion 50c that is recessed upward is formed at a position corresponding to the lower hinge 45 at one end in the longitudinal direction of the lower frame piece.

  The door closing device 44 is fitted into the shaft 45a of the lower hinge 45 and is supported so as not to rotate, and has a cam 46 made of synthetic resin in which at least a pair of recesses 46a are formed symmetrically about the axis of the lower hinge 45, and a tip. A leaf spring 47 that the portion 47a directly clamps the cam 46 from both sides and rotates along the outer periphery of the cam 46, and a spring holding that holds the leaf spring 47 and is fixed to the left door 3 of the refrigerator compartment It consists of a member 48 and a base member 49 that supports them. When the door is closed, the front end 47a of the leaf spring 47 is engaged with the recess 46a of the cam 46 when the door is closed, and the spring force is almost released, but the refrigerator left door 3 is opened. When it starts, it gradually disengages and is urged, and reaches the maximum when it reaches the outer peripheral surface. In other words, when the refrigerator compartment left door 3 is closed, the spring force that is urged to the maximum is applied to the recess 46a and is suddenly released. In addition, the pair of recesses 46 a formed in the cam 46 of the door closing device 44 is more than the position where the refrigerator compartment left door 3 is locked by the refrigerator main body 13 in the state in which the tip 47 a of the leaf spring 47 is engaged. It arrange | positions so that it may be located in a closing direction. The starting point of the pair of recesses 46a formed on the cam 46 of the door closing device 44 is automatically set by the left door 3 of the refrigerator compartment by the magnetizing force of a magnet gasket (not shown) disposed on the peripheral edge of the door inner plate. Of course, it is in a wider angular position than the open angular position to close. The door closing device 44 is configured to be biased by the leaf spring 47 directly pressing the outer periphery of the cam 46, that is, the cam 46 is configured to directly bias the leaf spring 47. The strength of closing the refrigerator compartment left door 3 is determined only by its own spring strength and the size and shape of the cam 46, and there is almost no variation. Therefore, even if the spring force is not adjusted after being installed in the refrigerator compartment left door 3, the spring force is too strong and the closing sound of the refrigerator compartment left door 3 becomes too loud or too weak and the refrigerator compartment door 3 is in the middle. The refrigerator compartment left door 3 can be reliably closed without stopping. Similarly, the refrigerator door right door 4 is provided with a door closing device 44 and a lower hinge 45, and the same effect can be obtained.

  Further, since the leaf spring 47 clamps the cam 46 from both sides, a large spring force can be obtained. In other words, in order to increase the closing force, the concave portion 46a of the cam 46 is deepened so that a large drop is not required and a large space for increasing the height of the leaf spring 47 is not required, and the spring itself is thickened. Therefore, workability is not deteriorated.

  As described above, in the refrigerator 1 of the present embodiment, the left front panel 31a is attached and fixed to the front surface portion of the left door frame frame 28 by the double-sided tape 30. According to such a fixing method, compared with the conventional fixing method in which the left front panel 31a is held in and fixed with a resin material such as PP (polypropylene) resin, the thickness of the refrigerator compartment left door 3 is set to the thickness of the resin material. It can be made thinner. The thickness of the refrigerator compartment left door 3 can also be reduced by reducing the thickness of the refrigerator compartment left door vacuum insulating material 16 or urethane (not shown), but in this case, the heat insulation properties deteriorate. End up. On the other hand, according to the refrigerator 1 of the present embodiment, even when a weak material such as glass is used for the left front panel 31a, an increase in the thickness of the refrigerator door left door 3 can be suppressed and heat insulation can be achieved. You can keep it. Further, a relief portion 28a3 is provided at the corner portion 28a6 of the left frame piece 28a. By providing the escape portion 28a3, 90 or more of the refrigerator compartment left door 3 can be opened without the left frame piece 28a hitting the left wall surface W. According to this configuration, even when the refrigerator 1 is installed with the left side surface 60a and the left wall surface W of the refrigerator 1 being close to each other, the refrigerator compartment left door 3 can be opened 90 degrees or more. The refrigerating room right door 4 has the same structure and has the same effect. Thus, the refrigerator compartment left door 3 and refrigerator compartment right door 4 can each be opened 90 degree | times, and the case and shelf in the refrigerator compartment 2 can be easily pulled out outside a store | warehouse | chamber.

  As the relief portion 28a3, a shape such as a C-chamfered shape, a circular arc shape, or a wave shape can be adopted, so that the degree of freedom in design is increased and the compatibility with the overall shape of the refrigerator 2 is considered. The design can be improved by selecting the shape. Further, if the relief portion 28a3 is formed in this way, the rotation axis center Q can be disposed close to the front surface of the left front panel 31a, and the condition C ≦ (A + t) for opening the left refrigerator compartment door 3 90 or more. ) Is easily satisfied. The same applies to the right refrigerator compartment door 4.

  Also, ribs are provided at both ends of the left and right frame pieces 28a and 28b, claw portions are provided at both ends of the upper and lower frame pieces 28c and 28d, and the ribs and claw portions are fitted together to form the left door frame frame 28 as a frame. By doing so, there is an effect that the left and right frame pieces 28a and 28b cannot be removed in the left-right direction. The same effect can be obtained for the right door frame frame 29.

  Further, since the reinforcing material 54 is fixed along the longitudinal direction inside the side surface of the left frame piece 28a, the left door frame frame 28 is foamed when urethane filled in the gap in the closed space of the left and right doors 3 in the refrigerator compartment is foamed. Can be prevented from being deformed. Further, since the rear surface of the left front panel 31a is fixed to the left door frame frame 28 by the urethane, the fixing strength of the left front panel 31a is increased, and the left front panel 31a is not easily detached from the left door frame frame 28. Play. The same applies to the right refrigerator compartment door 4.

  Conventionally, there has been a fixing method in which the periphery of the front panel is held with resin, but in this case, the area of the front panel when viewed from the front of the refrigerator is reduced, and the design is impaired. Furthermore, when the front and back surfaces of the front panel are held together with resin, dust or the like tends to accumulate in the gaps, and cleaning properties are not good. In turn, according to the refrigerator 1 of the present embodiment, the area of the left front panel 31a when viewed from the front of the refrigerator 1 can be increased to improve the design and cleaning properties. If glass is used as the material of the left front panel 31a, the design can be further improved. Further, the design can be further enhanced by attaching and fixing the left front panel 32 so that a part of the front surface of the left door frame frame 28 is exposed when viewed from the front. The same applies to the right refrigerator compartment door 4.

  The refrigerator 1 of this embodiment includes an operation panel 5. The operation panel 5 is a thin panel type operation panel, and even if the operation panel is installed in front of the left refrigerator compartment door 3, the thickness of the left refrigerator compartment door 3 hardly increases. In particular, if the operation panel 5 is installed in front of the left refrigerator compartment door 3 so that only the display screen of the operation content is exposed, the thickness of the left refrigerator compartment door 3 does not increase. Therefore, even if the operation panel 5 is provided on the front side of the left refrigerator compartment door 3, the left refrigerator compartment door 3 can be opened 90 or more, and an operation relating to the refrigerator 1 can be performed by a simple operation of touching the operation panel 5. Can do. The same applies when the operation panel 5 is provided on the right refrigerator compartment door 4.

  The refrigerator 1 of this embodiment includes a door closing device 44. When a user takes out food in the refrigerator compartment 2 and puts the food on the kitchen or table and then closes the door of the refrigerator compartment 2, the cold air inside the refrigerator is removed while the refrigerator left and right doors 3 and 4 are open. The temperature in the refrigerator compartment 2 will rise. If it does so, in order to cool the inside of the refrigerator compartment 2 where temperature rose, air volume will increase and time until the compressor 26 will stop will extend, and it will lead to deterioration of power consumption. Therefore, it is desirable that the refrigerator compartment left and right doors 3 and 4 have a structure that can be easily and reliably closed. According to the refrigerator 1 of the present embodiment, the refrigerator compartment left and right doors 3 and 4 can be opened up to 90 degrees even when the refrigerator 1 is arranged close to the wall surface, and the refrigerator compartment left and right doors 3 can be opened by the door closing device 44. And 4 can be closed easily and reliably.

  Although the said embodiment is an example at the time of providing the refrigerator compartment left door 3 and the refrigerator compartment right door 4 in order to open and close the refrigerator compartment 2, it is not restricted to this. Instead of the refrigeration room left door 3 and the refrigeration room right door 4, one door for opening and closing the refrigeration room 2 can be provided. Even in the case of the configuration in which the refrigerator compartment 2 is opened and closed with one door, the same effects as in the above embodiment can be obtained. In this case, the thickness of the refrigerator compartment door and the distance relationship between the refrigerator compartment door and the wall surface are the same as the thickness and distance relationship shown in FIGS.

  Although the said embodiment is an example at the time of providing the refrigerator compartment 2 in the uppermost stage, it is not restricted to this. For example, the positions of the refrigerator compartment 2 and the freezer compartment 4 can be switched. Further, the positions of the switching chamber 6 and the ice making chamber 8 can be switched. Thus, the positions of the rooms can be arbitrarily changed. Even when the replacement is performed, the same effect as the above embodiment can be obtained. In this case, the thickness of the refrigerator compartment door and the distance relationship between the refrigerator compartment door and the wall surface are the same as the thickness and distance relationship shown in FIGS.

  Although the said embodiment is an example at the time of attaching the door closing apparatus 44 to the lower hinge 45, the door closing apparatus 44 is not necessarily required. Moreover, although the said embodiment is an example when the back surface peripheral part of the left front panel 31a is fixed to the front frame part of the door left frame frame 28 with the double-sided tape 30, the fixing method is not restricted to this. For example, they can be fixed with an adhesive. The same applies to the right door.
