[0054] In the present embodiment, as the driving device, for example, it has a movable iron core that is pushed forward FR when an electromagnet is excited, and a cylindrical coil (not shown) provided around the movable iron core, and uses a solenoid structure or a solenoid method that moves the movable iron core disposed inside the cylindrical coil by an electromagnetic force obtained by passing an electric current through the cylindrical coil.

[0055] The left door opening device 41A and the right door opening device 41B can open the left refrigerator door 11Aa and the right refrigerator door 11Ab by causing the movable iron core to move straight forward by the electromagnetic force generated when an electric current flows through the cylindrical coil by the above-described driving device using the solenoid structure or the solenoid method. A driving device using the solenoid structure or the solenoid method may be referred to as a solenoid actuator.

[0056] With such a driving device, the movable iron core inside the cylindrical coil can be vigorously advanced by the electromagnetic force, and thus the left refrigerator door 11Aa or the right refrigerator door 11Ab can be vigorously pushed out in the opening direction. Note that the power by the movable iron core is transmitted to the left refrigerator door 11Aa or the right refrigerator door 11Ab while the movable iron core is in contact with the left refrigerator door 11Aa or the right refrigerator door 11Ab.

[0057] The left refrigerator door 11Aa and the right refrigerator door 11Ab are opened by the pressing force of the movable iron core, and then rotate to open to a predetermined angle by the inertia due to the pushed-out force. When the action of inertia weakens, the opening speed of the left refrigerator door 11Aa and the right refrigerator door 11Ab decreases. In this way, the left refrigerator door 11Aa and the right refrigerator door 11Ab are set to an open state to a certain extent.

[0058] The left door opening device 41A is disposed behind RR of the left refrigerator door 11Aa. The left door opening device 41A has a plunger 41P as the movable iron core that is pushed out forward FR when the electromagnet is excited, and the cylindrical coil (not shown) provided around the plunger 41P.

[0082] The connecting portion 516 is a claw for fixing a reinforcing plate 52 provided on the back surface of the button portion 511 to the main body portion 51. The connecting portion 516 is provided on the back surface of the button portion 511 and has a substantially L-shaped cross section along the horizontal direction (width direction W and depth direction D) as shown in FIG. 6.

[0083] The reinforcing plate 52 is a member separate from the main body 51 and is a plate-shaped member provided along the back surface of the main body 51. The dimension of the reinforcing plate 52 in the vertical direction V is larger than the dimension of the reinforcing plate 52 in the width direction W.

[0084] As shown in FIG. 6, the reinforcing plate 52 is sandwiched by the connecting portions 516 in the width direction W and fixed to the main body 51. Further, the reinforcing plate 52 is sandwiched by the buckle portion 511 and the connecting portion 516 in the depth direction D and fixed to the main body 51.

[0085] A plurality of connecting portions 516 are provided on the main body 51. The main body 51 has an appropriate number of connecting portions 516 according to the dimensions of the reinforcing plate 52 and the like. The connecting portion 516 only needs to be able to fix the reinforcing plate 52 to the back surface of the main body 51 and is not limited to claws. For example, the connecting portion 516 may have a caulking structure capable of fixing the reinforcing plate 52 to the main body 51 by thermal deformation.

[0086] A drying process for drying the paint applied to the decorative surface 511a is performed on the main body 51. Since the main body 51 is formed of resin, it may be deformed by drying in the drying process. Specifically, the main body 51 may warp forward FR or backward RR due to drying. When warping occurs in the main body 51, the decorative surface 511a and the outer surface 11s of the door 11 may not be able to maintain substantially the same plane, which may damage the appearance of the refrigerator 1.

[0087] The reinforcing plate 52 is a correcting member for correcting the warp of the main body 51. Therefore, the reinforcing plate 52 is preferably formed of a material having higher rigidity than the resin material forming the main body 51. For example, the reinforcing plate 52 is formed of metal.

[0088] Even when warping occurs in the main body 51, by attaching the reinforcing plate 52 to the back surface of the main body 51, the warp of the main body 51 is corrected by the rigidity of the reinforcing plate 52. Therefore, the decorative surface 511a and the outer surface 11s of the door 11 can be maintained substantially on the same plane, and the appearance of the refrigerator 1 can be improved.

[0089] As described above, a slit portion 51s is provided in a side rear protruding portion 514 provided on the back surface of the main body portion 51. By dividing the side rear protruding portion 514 by the slit portion 51s, it is possible to suppress the rigidity of the side rear protruding portion 514 from becoming too high, and it is possible to improve the effect of correcting the warp of the main body portion 51 by the reinforcing plate 52.

[0090] The correction of the warp of the painted parts by the reinforcing plate is not limited to the door opening operation portion 50, and can be applied to various painted parts constituting the refrigerator 1. For example, in the painted parts provided inside the storage chamber 27 of the housing 10 (inside the cabinet), a reinforcing plate may be provided on the back surface of the main body portion where the decorative surface is painted to correct the warp of the main body portion.

[0091] The case portion 53 is a case member that forms an accommodation space 50s capable of accommodating a sensor capable of detecting that the main body portion 51 has been pushed backward RR. As shown in FIG. 4, the case portion 53 is a box-shaped member having an opening in the front FR, and an accommodation space 50s capable of accommodating the above-described sensor is formed in the internal space of the opening.

[0092] The case portion 53 is provided inside the door 11 rather than the member forming the outer surface 11s of the door 11. That is, the case portion 53 is not exposed outside the door 11. As shown in FIG. 4, extended portions 53a and 53b facing the back surface of the member forming the outer surface 11s of the door 11 are provided at the upper and lower ends of the case portion 53. The extended portions 53a and 53b are continuously formed along the outer periphery of the case portion 53, and also face the back surface of the member forming the outer surface 11s of the door 11 at the left LT and right RT ends.

[0093] The extended portions 53a and 53b of the case portion 53 are, for example, seal portions that prevent the foam heat insulating material filled inside the door 11 from entering the accommodation space 50s of the case portion 53.

[0094] Here, as shown in FIG. 4, a predetermined gap is provided between the edge of the opening 11h of the door 11 and the main body 51. Further, the refrigerator 1 is used in the water area and may be touched with wet hands, and the outer surface 11s of the door 11 may be wetted with water.

[0095] On the back surface of the main body 51 of the door opening operation unit 50, an upper rear protruding portion 512 protruding rearward RR and an upper protruding portion 513 protruding upward UP from the tip of the upper rear protruding portion 512 are provided. Further, no notch (slit) is provided in the upper rear protruding portion 512.

[0096] Therefore, even when a liquid such as water enters the interior of the door 11 from the gap between the edge of the opening 11h of the door 11 and the main body 51 along the outer surface 11s of the door 11, the liquid falls onto the upper surface (the surface facing upward UP) of the upper rear protruding portion 512 and falls downward LO of the main body 51 along the side rear protruding portion 514 via the connecting portion 51c from the upper rear protruding portion 512.

[0097] The liquid that has fallen onto the upper surface of the upper rear protruding portion 512 does not flow rearward RR because it is blocked by the upper protruding portion 513, but flows in the width direction W in which the side rear protruding portion 514 is provided. As a result, it is possible to suppress the liquid from splashing on the electrical components such as the sensor housed in the housing space 50s, and it is possible to suppress malfunctions and malfunction of the electrical components.

[0098] Since the upper rear protruding portion 512 and the upper protruding portion 513 can suppress the intrusion of liquid into the housing space 50s, there is no need to provide a separate component for preventing the intrusion of liquid, and an increase in the number of components of the door opening operation unit 50 can be suppressed.

[0099] In the present embodiment, the refrigerator 1 includes a housing 10 including a storage chamber 27 having an opening, a door 11 attached to the opening of the housing 10 so as to be openable and closable, and a painted component (door opening operation unit) 50 provided on the housing 10 or the door 11. The painted component 50 includes a main body 51 formed of resin and having a painted surface 511a, and a correction member (reinforcing plate) 52 provided along the back surface of the main body 51 on the side opposite to the painted surface 511a of the main body 51 for correcting the warp of the main body 51.

[0100] According to such a configuration, even when the main body portion 51 warps due to drying, the warp of the main body portion 51 can be corrected by the reinforcing plate 52.

[0101] As a result, it is possible to provide the refrigerator 1 that improves the appearance of the resin parts to which painting is applied.

[0102] (Modification 1) In the above embodiment, the painting is applied to the decorative surface 511a of the button portion 511 of the main body portion 51, but the aspect of the main body portion is not limited to this. The painting may be applied not only to the decorative surface 511a but also to the back surface of the main body portion. Even when the painting is applied not only to the decorative surface 511a but also to the back surface, by providing the reinforcing plate 52 to the main body portion, the warp of the main body portion due to drying can be corrected.

[0103] (Modification 2) In the above embodiment, the side rear protruding portion 514 extends to the vicinity of the lower end of the main body portion 51, but the aspect of the side rear protruding portion is not limited to this. The side rear protruding portion may have a shape that extends from the upper rear protruding portion 512 to the vicinity of the center of the main body portion in the vertical direction V. Even if the side rear protruding portion does not extend to the vicinity of the lower end of the main body portion, it is possible to suppress the liquid from entering the accommodation space 50s.
