As shown in FIG. 1 and FIG. 2, the dishwasher main body 13 is provided with a washing tank 14, and an opening 15 of the washing tank 14 is formed by an upper door body (door body) 16 and a lower door body (door body) 17. It is configured to open and close. An upper support member 18 is fixed to the upper door body 16, and the upper support member 18 is pivotally supported on the base member 20 by an upper fixed pivot 19. A lower support member 21 is fixed to the lower door body 17, and the lower support member 21 is pivotally supported on the base member 20 by a lower fixed pivot 22.

  Further, a through hole into which a bolt 23 welded to the outer wall surface of the cleaning tank 14 is provided is provided at the lower portion of the base member 20 and is fixed by a nut 24.

  Further, an interlocking link 25 is provided as an interlocking means for interlocking the upper support member 18 and the lower support member 21. The upper link pivot 26 and the lower link pivot 27 are pivotally supported by the upper support member 18 and the lower support member 21, respectively. ing. The base member 20, the upper support member 18, and the lower support member 21 are provided on both the left and right sides of the cleaning tank 14.

  The lower door body 17 is provided with a push button switch 28 and a lock means 29 for fixing the lower door body 17 in the closed state, and interlocked with the push button switch 28 from the locking portion 30 provided in the cleaning tank 14 to the lock means. 29 can be released. The lock means 29 is linked with the input function of the operation of the dishwasher so that it is not operated when the lower door body 17 is not completely closed. Further, a seal member (not shown) having an elastic body is installed in the seal between the lower door body 17 and the upper door body 16 and the opening 15 and the seal between the lower door body 17 and the upper door body 16.

  Further, the interlocking link 25 is provided with a first holding part 31 and a second holding part 32, and the first holding part 31 is connected to the base member 20 by a first spring 33 (a tension coil spring). In the closed state of the door body, a force is applied to the open side, and in the open state, a force is applied in the closing direction. The second holding portion 32 is connected to the upper support member 18 by a second spring 34 (a tension coil spring), and is configured to apply a force in a direction to always open the upper door body 16. The first spring 33 and the second spring 34 constitute a mechanism for automatically opening the upper door body 16 and the lower door body 17 from the closed state to the open state.

  The base member 20 supports a sliding member 35 that slides on the upper support member 18. The sliding member 35 applies a load to the sliding surface with the upper support member 18 by a third spring 36. ing.

  Further, the upper support member 18 is made of resin, and a closed contact portion 37 and an open contact portion 38 are provided separately from the support portion of the upper door body 16, and the upper door body 16 is in a closed state and in the middle of opening. The sliding member 35 is in contact with the sliding member 35. Further, a spring holding portion 39 that holds the second spring 34 is provided between the upper fixed pivot 19 and the upper link pivot 26.

  Further, the pivot holding portion 40 that holds the upper link pivot 26 has a long hole shape in the direction of the substantially interlocking link 25 that can move at least upward from the position of the upper link pivot 26 in the closed state of the upper door body 16. It is configured to absorb the variation of the link mechanism and reliably close it.

  The operation in the above configuration will be described. The upper door body 16 and the lower door body 17 are configured to be opened and closed by the upper support member 18 and the lower support member 21 respectively, and the upper door is rotated by the rotation of the upper fixed pivot 19. The body 16 rotates upward, and the lower door body 17 rotates downward by the rotation of the lower fixed pivot 22.

  At this time, the locking means 29 is released by operating the push button switch 28 provided on the lower door body 17 by the interlocking link 25 biased to the open side by the first spring 33 and the second spring 34. Since the upper door body 16 and the lower door body 17 rotate in conjunction with each other, the user does not need to grasp the door body and perform an opening operation, and the upper door body 16 and the lower door body 17 are released from the closed state. It can be automatically released to the state.

  Further, the first spring 33 urges a force in the closing direction during the opening operation of the door body, so that the impact force when the door body is opened can be reduced.

  Further, the closing contact portion 37 provided on the upper support member 18 applies a force to the closing side by the sliding member 35 biased by the third spring 36, thereby delaying the opening speed of the door body, Even when the user operates the push button switch 28 during the operation, the opening speed of the upper door body 16 and the lower door body 17 immediately after release can be reduced, and the washing water sprayed simultaneously with the release of the locking means 29 Can be prevented from being ejected outside the dishwasher body 13.

  In addition, the friction force generated by the opening contact portion 38 and the sliding member 35 urged by the third spring 36 reduces the opening speed of the door body and reduces the impact force when opening. The rebound due to the impact of the lower door body 17 can be prevented.

  Further, the sliding member 35 is installed on the base member 20 on which the upper support member 18 and the lower support member 21 are installed, so that the error of the respective installation positions becomes only the processing error, and the upper door body 16 and the lower door body 17. The movement of the door body after assembly can be stabilized, for example, the variation in the opening speed and the impact force at the time of opening can be made extremely small.

  Even if the washing tank 14 is made of resin and the base member 20 is integrally formed, the same effect can be obtained and a dishwasher can be provided at a lower cost.

  In addition, since the base member 20 is a bolt / nut system, the base member 20 with the upper support member 18, the lower support member 21, the sliding member 35, and each spring attached thereto can be easily removed during maintenance inspection. And positioning after maintenance is easy.

  In the vicinity of the closed state of the upper door body 16, the second spring 34 generates a moment force that causes the upper door body 16 to act on the upper fixed pivot 19 and the spring support portion 39 in the closing direction. The position of the pivot 26 is such that the upper door body 16 can always be positioned in the closing direction in the pivot holding portion 40 having a long hole shape. With this configuration, it is possible to eliminate the poor linkage between the upper door body 16 and the lower door body 17 due to dimensional variations in the link configuration, and the opening and closing operation of the upper door body 16 and the lower door body 17 can be performed smoothly and stable sealing performance Can be secured.

  In the present embodiment, the first spring 33 and the second spring 34 constitute a mechanism for automatically opening the lid, but the upper support member 18 and the lower support that constitute the link mechanism. Either the member 21 or the interlocking link 25 may be driven by a motor or a solenoid, or the interlocking link 25 may be constituted by a wire and wound up by a motor, both of which obtain similar actions and effects. Can do.

As described above, the dishwasher according to the present invention automatically releases the upper door body and the lower door body in conjunction with each other, thereby eliminating troublesomeness during use and improving usability. Therefore, it is useful as a dishwasher or the like for storing dishes and washing by spraying washing water.
