(Embodiment 1)
1 to 3 show the configuration of the dishwasher according to Embodiment 1 of the present invention. 2 and 3, a first display unit 19 for displaying the operation state of the dishwasher and the like is provided on the upper front surface of the door 18. On the upper surface of the door 18, a power switch 20 for turning on / off the power, a start switch 21 for starting / pausing operation, a setting switch 22 for setting operation conditions such as an operation course and a drying time, and setting And a second display unit 23 for displaying operating conditions such as the driving course and the drying time. These switches 20, 21, 22 and the second display unit 23 provided on the upper surface of the door 18 are concealed in the cleaning machine body 1 when the cleaning tank 2 is stored in the cleaning machine body 1. It is configured.

  As described above, the display unit is divided into the first display unit 19 and the second display unit 23, and is optimally arranged in terms of both effective use of the arrangement location and appearance design. In other words, a setting course that is required before the start of operation where settings such as driving courses are set or during a temporary stop when setting changes are made, and does not necessarily require visual recognition during driving, and should be placed close to operation switches. The second display unit 23 that displays the operating conditions is arranged 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. In addition, the control unit 25 is provided with a buzzer 26 for notifying the user with a sound when the dishwasher is operated or when the operation is completed or detected.

  The control unit 25 does not accept any operation information from the power switch 20 and the start switch 21 when detection information is input from the storage detection unit 16 in the state where the cleaning tank 2 is stored (in the case of ON information). It is configured. On the other hand, when the detection information is not input from the storage detection unit 16 in the state where the cleaning tank 2 is pulled out (in the case of OFF information), any operation information of the power switch 20 and the start switch 21 is accepted. .

  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 conventionally 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, a case where the storage detection unit 16 is operating normally will be described. When the door 18 is closed and the operation of the dishwasher is stopped, the control unit 25 receives the ON information from the storage detection unit 16 and determines that the cleaning tank 2 is stored, and the power switch No operation information from 20 or the start switch 21 is accepted. At the same time, it waits for detection information from the storage detection unit 16 to be turned off. If the detection information from the storage detection unit 16 is turned off, any operation information of the power switch 20 and the start switch 21 is accepted.

  Then, the power switch 20 is turned on by the user, the operation conditions such as the operation course and the drying time are set by the setting switch 22, and after the start switch 21 is pressed, the cleaning tank 2 is stored in the main body 1. When the detection information from the storage detection unit 16 is switched from OFF to ON, that is, the door 18 is closed, the control unit 25 starts operation according to the operation conditions such as the set operation course and drying time, The operation state and the like are displayed on the first display unit 19 provided on the upper front surface of the door 18.

  During operation, the control unit 25 is waiting for detection information from the storage detection unit 16 to be turned off. In the meantime, any operation information from the power switch 20 and the start switch 21 is not accepted. However, in this state, all the switches such as the power switch 20 and the start switch 21 are hidden in the main body 1 of the washing machine, and the switches cannot be operated structurally.

  When the door 18 is opened by the user and the detection information from the storage detection unit 16 is turned off, the control unit 25 temporarily stops the operation. When the door 18 is closed again and the detection information from the storage detection unit 16 is turned on, the operation is resumed. The control unit 25 ends the operation if the power switch 20 is operated during the temporary stop, and accepts the change if the operation condition such as the operation course and the drying time is changed by the setting switch 22. Thereafter, the door 18 is closed, and the detection information from the storage detection unit 16 is turned ON, so that if the course has been changed, the operation is resumed with the course changed.

  As described above, when the cleaning tank 2 is housed in the main body 1, all the switches such as the power switch 20 and the start switch 21 are hidden in the main body 1, and the power switch 20 and the start switch 21 are started. Since any operation information from the switch 21 is not accepted, in normal use in which the storage detection unit 16 is operating normally, the switches can be operated only when the cleaning tank 2 is pulled out. .

  In the state where the cleaning tank 2 is stored such as during operation, the switches cannot be operated structurally. Therefore, while the storage detection unit 16 detects the storage state, the storage detection unit 16 detects the storage state. Even if control is performed so that the information is ON and neither operation from the power switch 20 and the start switch 21 is accepted, there is no problem in normal use.

  Next, an operation when the storage detection unit 16 fails will be described. In the case where the storage tank 16 is erroneously detected as being stored although the cleaning tank 2 is pulled out due to a failure of the storage detector 16, detection information (ON information) is being input from the storage detector 16. As a result, the control unit 25 does not accept operations such as the power switch 20 and the start switch 21. Thereby, it is possible to prevent a malfunction that the operation is started due to a failure of the storage detection unit 16, and it is possible to prevent an abnormal operation such as the flushing water jumping out.

  In addition, when the power switch 20 or the start switch 21 is pressed in this state, these switches are not structurally operated in the state where the washing tub 2 is originally housed. Judge as abnormal. At the same time, the dishwasher, in particular the washing tub 2 is pulled out by blinking the door opening lamp 24 provided on the second display unit 23 and visually informing it or by audibly informing the buzzer 26. It is possible to notify the user that there is an abnormality such as a failure in the device related to the storage detection unit 16 that detects that the storage state is in the state.

In addition, when it is erroneously detected that the cleaning tank 2 is stored due to a failure of the storage detection unit 16, the detection state is not input from the storage detection unit 16 (OFF information state). Thus, the control unit 25 is in a state of accepting operations such as the power switch 20 and the start switch 21, but all the switches are concealed in the cleaning machine main body 1, and the switches cannot be operated structurally. Moreover, since the detection information from the storage detection part 16 is not ON, the abnormal operation | movement that a driving | operation is started can be prevented.

  In addition, since the power switch 20 and the start switch 21 are arranged in a position that is concealed in a state where the cleaning tank 2 is housed, the switches are not touched by the body during operation, and an erroneous operation in an unconscious state is prevented. At the same time, it can also function as a child lock.

  Moreover, the 1st display part 19 which displays a driving | running state is arrange | positioned in the front surface of the door 18 which can be visually recognized also in the state which accommodated the washing tank 2, and the 2nd display part 23 which displays a setting course and a driving | running condition is the The upper surface of the door 18 whose area tends to be narrowed due to the necessity of securing the volume in the cleaning tank 2 is effectively used by being disposed on the upper surface of the door 18 that is concealed in a state in which the cleaning tank 2 is accommodated. In addition, the front face of the door 18 can be kept to the minimum necessary display, and the front face can be refreshed and simplified to improve the appearance design of the dishwasher and to improve the sense of unity with the system kitchen.

  Note that the correspondence between the presence / absence of detection information from the storage detection unit 16 and whether or not to accept operation information from the power switch 20 and the start switch 21 of the control unit 25 is the same as that of the present embodiment. However, it can be similarly realized.

  Moreover, although the 1st display part 19 was supposed to display a driving | running state, it is not limited only to the display of a driving | running state, If it is the range which can be accept | permitted on an external design, for example, a setting course etc. will be displayed, You may be able to check the course during driving.

  As described above, in the dishwasher according to the present invention, the power switch and the start switch are arranged at a position concealed in the state where the washing tub is stored, and the storage detection unit detects that the cleaning tub is in the storage state. In the state, it is configured not to accept the operation of the power switch and start switch, eliminating the switch on the front, improving the sense of unity between the system kitchen and the dishwasher, preventing malfunction, and failure of the storage detector Therefore, it is useful as a built-in type dishwasher or the like that pulls out the washing tank and puts in and out dishes.
