Description

  The present invention relates to a dishwasher for cleaning dishes and the like by jetting washing water.

  Conventionally, this type of dishwasher has been considered to be configured as shown in FIG. 12 (see, for example, Patent Document 1). The dishwasher described in Patent Document 1 stores an object to be cleaned such as tableware in a cleaning tank, and closes an opening 101 provided in the cleaning tank with an upper door body 102 and a lower door body 103, and then a cleaning pump. The cleaning and rinsing steps of the object to be cleaned are performed by operating and spraying cleaning water. On the other hand, the upper door body 102 is configured to be opened and closed by being moved to an upper space of the main body 105 by the upper door support member 104.

  Further, since the lower door support member 106 and the upper door support member 104 are connected by an interlocking member 107, when the lower door body 103 is opened and closed, the upper door body 102 is also opened and closed in conjunction with the opening and closing operation. Since the front opening 101 can be opened and closed, a user-friendly dishwasher is realized.

  On the other hand, the washing pump automatically stops when the washing and rinsing process is completed, but also stops the operation when the user presses the pause button during the washing and rinsing process. However, if the unlocking operation for holding the upper door body 102 and the lower door body 103 in the closed state is performed without pressing the pause button, the upper door body 102 and the lower door body are operated with the cleaning pump operating. Since 103 is opened and the front opening 101 is opened, there is a problem that washing water jumps out of the apparatus.

Therefore, a safety switch linked with the door body locking means is provided so that the washing pump does not operate when the door body is not closed, and the door body locking means is released during the operation of the washing pump. In such a case, it is considered that the operation is immediately stopped (for example, see Patent Document 2).

  However, in the conventional configuration described in Patent Document 1, since the upper door body 102 and the lower door body 103 are operated at the same time when the push button switch for releasing the lock unit is pressed, the opening 101 is greatly opened. Even if the operation of the cleaning pump is stopped simultaneously with the release of the locking means, the cleaning water is jetted for a certain time due to the inertia of the cleaning pump and does not stop instantaneously. It had the problem of jumping out of the plane.

  In addition, it is described in Patent Document 2 that the door body is locked so that it cannot be opened during operation, but when additional tableware is added after the start of operation, an operation to stop the operation is required each time. It is inconvenient and inconvenient. Since the door lock is also released by this operation, even if the operation of the cleaning pump is stopped simultaneously with the operation of the operation stop, the washing water jumps out due to the inertia of the cleaning pump as described above. There was a problem that could not be solved.
