And a second display unit 23 for displaying operating conditions such as the set operation course and drying time. These switches 20, 21, 22 and the second display unit 23 provided on the upper surface of the door 18 are configured to be concealed in the main body 1 when the washing tub 2 is stored in the main body 1 of the dishwasher. Has been.

  As described above, the display unit is divided into the first display unit 19 and the second display unit 23, and is arranged in consideration of both effective use of the arrangement location and appearance design. In other words, it is necessary before the start of driving where settings such as driving courses are set or at the time of temporary stop when setting changes are made, and does not necessarily require the user's visual recognition during driving, and should be placed close to the operation switches. The second display unit 23 that displays the set course and the operating conditions is disposed on the upper surface of the door 18 that is concealed in a state where the cleaning tank 2 is stored. On the other hand, the first display unit 19 that displays the operation state that does not need visual recognition when setting before starting operation or temporarily changes to change the setting and requires visual recognition after operation starts stores the cleaning tank 2. It is arranged on the front surface of the door 18 that can be visually recognized even in the state of being.

  As shown in FIG. 3, the second display unit 23 is provided with a door opening lamp 24 for displaying that the cleaning tank 2 is pulled out and the door 18 is open. A storage detector 16 that detects whether or not the cleaning tank 2 is stored is provided below the cleaning tank 2. Inside the door 18 is provided a control unit 25 that controls the operation of the dishwasher. The control unit 25 turns on or off the door opening lamp 24 based on the detection information from the storage detection unit 16.

  Further, the control unit 25 is provided with a time measuring unit 27 that measures an elapsed time after detecting the operation start information from the start switch 21. In addition, the control unit 25 is provided with a notifying unit 26 including a buzzer and a sound device for notifying the user with sound when operating the dishwasher or detecting the end of operation / abnormality. Then, the storage detection unit 16 detects that the door 18 is closed even when the elapsed time measured by the time measuring unit from the time when the start switch 21 is operated exceeds the predetermined time T1. If not, the notification unit 26 is configured to notify that the operation is not started and that it is abnormal.

  About the dishwasher comprised as mentioned above, the operation | movement and an effect | action are demonstrated. Since the basic operation and action of the dishwasher are the same as those of a well-known built-in type dishwasher, a description thereof will be omitted, and the operation, operation, and display in the operation display unit will be described below.

  First, an operation in the case where the control unit 25 does not notify that it is abnormal because the operation cannot be started will be described. The user pulls out the door 18 and the washing tub 2 from the state in which the door 18 is closed, places the tableware 3 in the washing basket 4 and accommodates it in the washing tub 2, and puts detergent into the washing tub 2. Next, when the power switch 20 is pressed, the control unit 25 can accept setting of operation conditions such as an operation course and a drying time by the setting switch 22. When the user finishes setting the operation course and the drying time, the user then presses the start switch 21 to start the operation, and closes the door 18 within a predetermined time T1 (for example, 5 seconds). That is, as the cleaning tank 2 is stored in the main body 1, the control unit 25 detects that the detection information from the storage detection unit 16 is switched from OFF to ON within a predetermined time T <b> 1 after the start switch 21 is operated. Detect that. Then, the control unit 25 starts the operation according to the set operation conditions such as the operation course and the drying time, and displays the operation state and the like on the first display unit 19 provided on the upper front surface of the door 18.

  Next, the operation in the case where the control unit 25 notifies that it is abnormal that the operation cannot be started will be described. The user pulls out the door 18 and the washing tub 2 from the state in which the door 18 is closed, places the tableware 3 in the washing basket 4 and accommodates it in the washing tub 2, and puts detergent into the washing tub 2. Next, when the power switch 20 is pressed, the control unit 25 can accept setting of operation conditions such as an operation course and a drying time by the setting switch 22. When the user finishes setting the driving course and drying time, the user then presses the start switch 21 to close the door 18 in order to start driving.

  At this time, after detecting the operation of the start switch 21, the control unit 25 starts a countdown of a predetermined time T1 (for example, 5 seconds) by the time measuring unit 27. However, if the door 18 is not completely closed for some reason contrary to the user's will, the detection information from the storage detection unit 16 is not detected until the countdown of the predetermined time T1 by the time measuring unit 27 ends. Does not turn from OFF to ON. That is, the control unit 25 determines that the door 18 is not closed even after the predetermined time T1 has elapsed, and notifies the user of the abnormality by the notification unit 26, assuming that the operation cannot be started.

The predetermined time T1 is preferably a time within a range where the notification of the notification unit 26 can be heard as much as possible even if the user moves from the place after closing the door 18. Of course, if the detection information from the storage detection unit 16 is turned from OFF to ON before the door 18 is closed again and the countdown by the timing unit 27 is finished, the control unit 25 notifies the abnormality by the notification unit 26. Without starting, operation is started as it is.

  As described above, according to the configuration of the present invention, the sense of unity and design between the system kitchen and the dishwasher are improved by eliminating the switch from the front, and the start switch is operated with the door changed accordingly. Only when the door is not completely closed while responding to the operation procedure of closing the door, it can be informed that the operation cannot be started and that it is abnormal.

(Embodiment 2)
A dishwasher according to a second embodiment of the present invention will be described with reference to FIGS. The dishwasher of the second embodiment is the same component as that of the first embodiment, and only the control method by the control unit 25 is different. The operation and action will be described below.

  The user pulls out the door 18 and the washing tub 2 from the closed state of the door 18, places the tableware 3 in the washing tub 4 in the washing tub 4 and stores it in the washing tub 2, and puts the detergent into the washing tub 2. To do. Next, when the power switch 20 is pressed, the control unit 25 can accept setting of operation conditions such as an operation course and a drying time by the setting switch 22. When the user finishes setting the driving course and drying time, the user then presses the start switch 21 to start driving. When detecting the operation of the start switch 21, the control unit 25 starts a countdown of a predetermined time T <b> 1 (for example, 5 seconds) by the time measuring unit 27.

  Here, before the user closes the door 18, for example, when the user notices that the tableware 3 is forgotten to be inserted, the user starts and pauses the operation so that the user is not notified of an abnormality that the operation cannot be started. The start switch 21 is pressed to temporarily stop the operation. When detecting a temporary stop operation by the start switch 21, the control unit 25 stops the countdown of the predetermined time T <b> 1 by the time measuring unit 27 so as not to notify the abnormality that the operation cannot be started. Thereafter, the user adds the tableware 3 and presses the start switch 21 again to restart the operation. When the control unit 25 detects the operation of the start switch 21 during the temporary stop state, the control unit 25 resets the counter for the predetermined time T1, and counts down the predetermined time T1 from the beginning, not from the middle of the stopped counter. Start. That is, for example, when the predetermined time T1 is 5 seconds and the start switch 21 is pressed for a temporary stop at the remaining 2 seconds, when the operation is resumed, the predetermined time T1 is not counted down from 2 seconds. Countdown starts from 5 seconds of time T1.

  When the door is not closed even after the predetermined time T1 elapses, the control unit 25 detects that the count from the storage detection unit 16 is not reached until the time counting unit 27 counts down (becomes zero). If the detection information does not change from OFF to ON, the notification unit 26 notifies the driver that the operation cannot be started and is abnormal. Moreover, if the detection information from the storage detection part 16 turns from OFF to ON before the countdown by the time measuring part 27 ends, the control part 25 does not perform the notification by the notification part 26 and starts driving.

  As described above, according to the configuration of the second embodiment, when the user cancels the temporary stop state, the notification that it is abnormal that the operation cannot be started is always performed after a predetermined time has elapsed. The user can always carry out with sufficient margin without preparing for driving.

In addition, although the above embodiment demonstrated the dishwasher of the structure which moves a washing tank to the front-back direction and takes in / out from a main body, it does not restrict to this. For example, the door is fixed to the opening of the main body so that it can be opened and closed with a hinge, and the cleaning basket is put in and out. Such a configuration is also included. Further, the storage detection unit is not limited to detecting whether or not the cleaning tank is stored, and may be one that detects opening and closing of the door.

  As described above, in the dishwasher according to the present invention, the start switch is disposed at a position where it is concealed when the door is closed, and the door is changed in accordance with the opening of the door. Corresponding to the operation procedure of closing the door, only when the door is not completely closed, the user is informed that it is abnormal that the operation cannot be started, and the user surely executes the washing of the dishes. It can be applied to a dishwasher in which the start switch is hidden during operation.
