Description

Embodiments of the present invention relate to refrigerators.

In recent years, with the widespread use of mobile information terminals such as smartphones and tablets, for example, household chores have come to be used while watching videos and music on mobile information terminals. However, since the battery consumption associated with viewing moving images and music is relatively large, the user needs to pay attention to the remaining battery level of the mobile information terminal. Therefore, for example, a configuration has been proposed in which a connection terminal to which an external device such as a mobile information terminal can be connected is provided in the refrigerator, and the refrigerator and the external device can be electrically connected to supply power from the refrigerator to the external device. ..

However, for example, every time power is supplied from the refrigerator to an external device, a cable or the like connecting the external device and the connection terminal is connected and disconnected, so that the connection terminal may be physically loaded when used frequently. Therefore, for example, as a result of frequent use for a long period of time, the connection terminal may be broken and an external device may not be able to be connected to the refrigerator.

As shown in FIG. 8, the claw portion 56 is provided so as to project downward from the upper portion 51, and the tip is curved so as to be formed on the L-shaped side as a whole. The claw portion 56 is locked to the side portion forming the thickness direction of the substrate 31 by the curved portion 561 at the tip. Therefore, the claw portion 56 restricts the movement of the substrate 31 in the vertical direction.

The fitting portion 55 projects downward from the upper portion 51 to form an inverted U shape. Further, as shown in FIG. 7, the substrate 31 has a fitted portion 311. The fitted portion 311 is formed by cutting out a piece in the longitudinal direction of the substrate 31, in this case, a part of the upper side thereof, and fits with the fitting portion 55 to restrict the movement of the substrate 31.

That is, when the connection unit 30 is attached to the holding member 50, the substrate 31 and the claw portion 56 are locked to restrict the movement of the substrate 31 in the vertical direction, and the fitted portion 311 and the fitting portion 55 are connected to each other. The fitting restricts the movement of the substrate 31 with respect to the insertion / removal direction of the connector 82. In this case, when the holding member 50 and the connecting unit 30 are accommodated in the accommodating portion 40, the thickness direction of the substrate 31 is parallel to the inner wall 431. That is, the longitudinal side and the familiar side of the substrate 31 are perpendicular to the inner wall 431. Further, in the present embodiment, the longitudinal side of the substrate 31 is parallel to the insertion / removal direction of the external device 80 and is inclined with respect to the left-right direction.

The upper portion 51, the fitting portion 55, and the claw portion 56 are formed by integrally molding a synthetic resin such as plastic. Therefore, the fitting portion 55 and the claw portion 56 basically bend in the insertion / removal direction of the external device 80 in the state where the holding member 50 is accommodated in the accommodating portion 40, except that the fitting portion 55 and the claw portion 56 are bent to allow the substrate 31 to be attached. It is also immovable in the front-back direction.

As shown in FIGS. 3 to 5, the refrigerator 1 further includes a lid member 60. The lid member 60 has a lid main body 61 and a sandwiching portion 62. The lid body 61 forms a plane parallel to the horizontal plane, and has a function of opening and closing the opening 41 of the accommodating portion 40 in a detachable manner. Further, the sandwiching portion 62 projects upward from the lid main body 61 and is formed in a U shape. The lid body 61 and the sandwiching portion 62 are integrally molded with a synthetic resin such as plastic.

When the opening 41 is closed by the lid member 60 in a state where the connection unit 30 held by the holding member 50 is housed in the housing portion 40, one side of the lower side of the substrate 31 is formed in the U-shaped groove of the sandwiching portion 62. Be sandwiched. As a result, the movement of the substrate 31 in the thickness direction is restricted.

As shown in FIGS. 2, 3 and 6, the connecting portion 33 is formed in a cylindrical shape having a substantially rectangular outer shape. The connecting portion 33 has a locking portion 331. In the present embodiment, the connecting portion 33 has a plurality of connecting portions 33, in this case, four locking portions 331. The locking portion 331 is formed by folding outward the front side of the connecting portion 33 with respect to the insertion direction, that is, the recessed portion 212 side with respect to the accommodating portion 40, and the right end portion in the case of the present embodiment. The locking portion 331 extends in a direction perpendicular to the insertion / removal direction of the connector 82. In a state where the connection unit 30 is mounted on the holding member 50, at least one locking portion 331 of the plurality of locking portions 331 is locked in the recess 54 of the holding member 50. In this embodiment, three locking portions 331 are locked in the recess 54. That is, the three locking portions 331 located on the upper side, the front side, and the rear side are locked to the upper side, the front side, and the rear side portion of the recess 54, respectively. The locking portion 331 located on the lower side of the four locking portions 331 is not locked to the recess 54 because the recess 54 is formed in an inverted U shape.

Further, in a state where the connection unit 30 and the holding member 50 are accommodated in the accommodating portion 40, at least one locking portion 331 of the plurality of locking portions 331 is on the front side, that is, in the accommodating portion with respect to the insertion direction of the connector 82. The recessed portion 212 side with respect to the portion 40 is locked to the inner wall 431. In this embodiment, four locking portions 331 are locked to the inner wall 431. Further, as described above, the locking portion 331 is locked in the recess 54 on the back side with respect to the insertion direction of the connector 82, that is, on the accommodating portion 40 side with respect to the recessed portion 212. Therefore, when the connector 82 is inserted into the connection unit 30, the force received by the connection portion 33 in the insertion direction is received by the recess 54 and eventually the holding member 50 via the locking portion 331. Further, when the connector 82 is pulled out from the connecting unit 30, the force received by the connecting portion 33 in the pulling direction, that is, in the semi-insertion direction is received by the inner wall 431 and eventually the door 21 via the locking portion 331.

Here, when the connecting portion 33 does not have the locking portion 331, the connecting portion 33 and the holding member 50, and the connecting portion 33 and the inner wall 431 are not locked. In that case, all the forces in the insertion / removal direction received by the connection portion 33 when the connector 82 is inserted / removed are received by the connection portion 33. Since the substrate 31 is regulated so as not to move in the insertion / extraction direction due to the fitting of the fitting portion 55 and the fitted portion 311 as described above, the force received by the connecting portion 33 is the same as that of the connecting portion 33. Concentrate on the fixed portion with the substrate 31, for example, the soldered portion. As a result, there is a risk that the substrate 31 and the connecting portion 33 may rattle due to long-term use or excessive use, the connecting portion 33 may come off from the substrate 31, and the connection unit 30 may be defective.

According to the embodiment described above, the refrigerator 1 includes a refrigerator main body 10 and doors 21, 22, 23, 24, 25, 26. The refrigerator body 10 has storage chambers 11, 12, 13, 14, and 15. The doors 21, 22, 23, 24, 25, and 26 are provided in the refrigerator main body 10, and open and close the corresponding storage chambers 11, 12, 13, 14, and 15, respectively. The refrigerator 1 includes a connecting portion 33 provided on the door 21 and a substrate on which the connecting portion 33 is mounted. The external device 80 can be directly or indirectly inserted and connected via the cable 81. The connecting portion 33 has a locking portion 331 that is locked to the door 21 and extends in a direction different from the insertion / removal direction of the external device 80. In this case, specifically, the connecting portion 33 has a locking portion 331 that is locked to the door 21 and extends in a direction perpendicular to the insertion / removal direction of the external device 80.

According to this, since the locking portion 331 is locked to the door, there is little wobbling of the substrate 31 when the external device 80 is inserted and removed, and the stability during use is excellent. Further, since the locking portion 331 extends in a direction different from the insertion / removal direction of the external device 80, the force received by the locking portion 331 in the insertion / removal direction can be released to the door when the external device 80 is inserted / removed. .. Specifically, since the locking portion 331 extends in a direction perpendicular to the insertion / removal direction of the external device 80, the force received by the locking portion 331 in the insertion / removal direction when the external device 80 is inserted / removed is applied. You can escape to the door more efficiently. Therefore, it is possible to suppress the application of force to the fixed portion between the connection portion 33 and the substrate 31, suppress rattling and falling off even after long-term use, and reduce the occurrence of defects in the connection unit 30. can do. As described above, according to the present embodiment, when the external device 80 is inserted into and removed from the connection portion 33 included in the refrigerator 1, the load applied to the connection portion 33 itself and the substrate 31 on which the connection portion 33 is mounted can be reduced. can.

Further, the locking portion 331 is located on the front side with respect to the insertion direction of the external device 80 with respect to the entire connecting portion 33. According to this, since the locking portion 331 is located in the front portion in the insertion direction where a force is easily applied when inserting and removing the external device 80, the force when inserting and removing can be released to the door 21 more efficiently. .. Therefore, it is possible to further suppress the application of force to the fixed portion between the connecting portion 33 and the substrate 31, suppress rattling and falling off even after long-term use, and cause a defect in the connecting unit 30. Can be reduced.

Further, the locking portion 331 is formed by folding back the end portion of the connecting portion 33 on the front side with respect to the insertion direction of the external device 80. Therefore, the locking portion 331 is integrally formed with the connecting portion 33. According to this, the strength can be further increased and the manufacturing cost can be reduced as compared with the case where the connecting portion 33 and the locking portion 331 are made of separate members.

Furthermore, the refrigerator 1 further includes a fitting portion 55 provided on the door 21. The substrate 31 is provided on a side extending in the insertion / extraction direction of the external device 80 among the peripheral sides of the substrate 31, and in this case, has a fitted portion 311 provided on the upper side and fitted with the fitting portion 55. ing. According to this, the movement of the external device 80 in the insertion / removal direction is restricted by the fitting of the fitting portion 55 and the fitted portion 311. Therefore, it is possible to suppress the occurrence of rattling of the substrate 31 when the external device 80 is inserted and removed, and as a result, it is possible to suppress the aged deterioration of the connection unit 30.

Furthermore, the insertion direction of the substrate 31 into the door 21 is different from the insertion / removal direction of the external device 80. In this case, the insertion direction of the substrate 31 into the door 21 is perpendicular to the insertion / removal direction of the external device 80. According to this, since the board 31 is not premised on moving in the insertion / removal direction of the external device 80 when installed on the door 21, the board 31 moves together in the insertion / removal direction when the external device 80 is inserted / removed. Therefore, it is possible to prevent the substrate 31 from rattling.

Furthermore, the refrigerator 1 includes a holding member 50 that holds the connecting portion 33 and the substrate 31, and an accommodating portion 40 that has an opening 41 that communicates with the outside and accommodates the substrate 31, the connecting portion 33, and the holding member 50. It has an inner wall 431 that blocks the accommodating portion 40 from the outside at least partially. The locking portion 331 is locked to the holding member 50 and the inner wall 431.

According to this, the locking portion 331 is locked to the inner wall 431 on the front side with respect to the insertion direction of the external device 80, and is locked with the holding member 50 on the back side with respect to the insertion direction of the external device 80. In this case, the force applied to the connecting portion 33 when the external device 80 is inserted into the connecting portion 33 is transmitted from the locking portion 331 to the holding member 50. Further, the force applied to the connecting portion 33 when the external device 80 is pulled out is transmitted from the locking portion 331 to the inner wall 431. Therefore, it is possible to suppress the force applied to the connecting portion 33 from being applied to the fixed portion between the connecting portion 33 and the substrate 31 in any movement in the insertion / removal direction of the external device 80.

The door 21 has an opening 41 communicating with the outside, an accommodating portion 40 for accommodating the substrate 31 and the connecting portion 33, and a lid member 60 for closing the opening 41. The lid member 60 has a sandwiching portion 62 that sandwiches a part of the substrate 31 and restricts the movement of the substrate 31 in the thickness direction. According to this, the movement of the substrate 31 in the thickness direction, that is, the movement in the direction perpendicular to the insertion direction of the external device 80 is restricted. Therefore, the rattling of the substrate 31 when the external device 80 is inserted is reduced, and the usability can be improved.

The locking portion 331 may be configured to lock at least one of the insertion / removal directions of the external device 80. That is, the locking portion 331 may be configured to be locked to at least the inner wall 431 or at least to the holding member 50.

Further, the locking portion 331 may be provided not only at the end portion of the connecting portion 33 on the front side with respect to the insertion direction of the external device 80, but also at any portion of the side extending in the insertion direction of the connecting portion 33. For example, the locking portion 331 is provided on the back side with respect to the insertion direction of the connection portion 33, that is, on the accommodating portion 40 side with respect to the recessed portion 212, or between the front side and the back side with respect to the insertion direction of the connection portion 33. It may have been. Further, the locking portion 331 may be provided on a part of the four surfaces of the cylindrical portion forming the connecting portion 33, for example, one of the upper and lower surfaces and one of the upper and lower surfaces.

In the above embodiment, the terminal according to the USB standard is disclosed as an example of the connection portion 33, but the connection portion 33 is not limited to the terminal according to the USB standard as long as it is of a standard capable of supplying power.
Further, the external device 80 connected to the connection unit 30 may be a personal computer or the like in addition to a portable information terminal such as a smartphone or a tablet.
