点で不導通の区間を生じる。Conventional configuration and its problems Generally, in the case of a dishwasher that uses a slow-acting automatic time switch, when the automatic time switch's contact is switched from the top side to the bottom side, the contact is free and is lowered from the top to the bottom. As the cam rotates, it can quickly switch from the top side to the bottom side. However, when switching from the bottom side to the top side, the contacts are pushed up from the bottom to the top due to the inclination of the cam, resulting in a non-conducting section at the time of switching.

いように動作に応じた方向に配設する。 FIG. 2A shows an example of an intermittent feed type slow movement time switch, and 14 is a sub cam that is linked to a timer motor and is a partially toothed gear. 15 is sent intermittently by the main cam, and the operation is sent by the sub cam, so it moves gradually. Figure 2B is an enlarged view of the main cam.The T line is the part of the outside diameter of the cam that turns on the top T side of the contact, the N line is neutral, and the B line turns on the bottom B side of the contact. A predetermined operation is performed by switching the time switch configured as described above, and when switching, the contact can be instantly switched from the top side to the bottom side, and the contact can be switched instantly from the top side to the bottom side. The time during which the switch is not turned on is negligible, but since the contact is lifted from the bottom to the top, the bottom side
It is impossible to ignore the time during which neither contact is turned on between when it turns off and when the top side turns on. The present invention takes this point into consideration and arranges the main cam 15, which switches the contacts, in a direction that corresponds to the movement so as not to cause malfunction.

In the process, the normally closed contact 4 of relay 3 is connected to the power supply.
Top side of T ₈ , H contact of select switch 8,
The timer motor 9 can be energized through the bottom side of the contact _T3 . In this case, if the normally-closed contact 4 of the relay is connected to the timer motor 9 without passing through the main contact, when the time switch shaft is forcibly rotated manually, it may rotate to other electrical components. The motor malfunctions and rotates even though there is no water in it. Therefore, in this embodiment, the contact from the relay contact 4 to the timer motor 9 is switched from the top side to the bottom side, and the power line from the normally closed contact 4 of the relay is switched from the top side to the bottom side. The timer motor can be energized continuously without overlapping the power line and the power line that passes through the main contact of the time switch. The relay is controlled by a temperature control switch. By doing this, time control, temperature control, and time control can be performed. In addition, if the heater
Energization to the timer motor can be started at the same time as it is turned off.

When contact _T3 is switched to the bottom side, it is connected to the normally closed contact of the relay from the top side of contact _T8 through the H side of the select switch. Contact _T3 switches from the top side to the bottom side, so there is no overlap. Next, when switching from process J to process K (temperature control to time control), overlapping of the power supply lines does not occur by switching contact _T8 from the top side to the bottom side. Further, by turning on a select switch between contact point _T3 and contact point _T8 , it is possible to control the time of process C and process J.
