FIG. 2 shows an example in which the communication unit 2 is always provided with power via the communication power line 21.

Further, the first sensor 61 and the second sensor 63 not only transmit an electrical signal to the second control unit 9 but also transmit an electrical signal to the first control unit 8, which can determine whether the door has opened the door As shown in FIG.

Fig. 3 shows an example of a control method of the dishwasher having the above-described structure.

The control method of the present invention is characterized in that the control unit includes a holding step S11, S13 and S15 for maintaining a state in which power is supplied to the sensing unit 6 and the second control unit 9, A first control unit power supply step S52 for supplying power to the first control unit 8 when the first control unit 8 is opened and the first control unit 8 for supplying power to the first control unit 8 when the first control unit 8 causes the lamp 7 to emit light to the tub 11 And a lamp power supply step (S53).

The maintenance steps S11, S13 and S15 are performed by the second control unit power line 91 (FIG. 9) without the user supplying power to the first control unit 8, the control command input unit 53 and the display unit 55 via the power input unit 51 And supplying power to the second control unit 9 and the sensing unit 6 through the sensing unit power line 65. [

That is, in the step S11, the power is supplied to the second control unit 9 even if the power supply signal through the power input unit 51 is not input, (S13, S15) of supplying power to the first sensor 61 and the second sensor 63 even if no input is made.

The first control unit power supply step S52 is performed when the input port 111 is opened. The step S51 of determining whether the input port 111 is opened is performed by the first sensor 61 and the second sensor 2 sensor 63 to determine whether the second control unit 9 has received a signal indicating that the input port 111 is opened.

When the second control unit 9 receives an electrical signal generated when the input port 111 is opened from the first sensor and the second sensor, the second control unit 9 controls the second power line switch 81 (S52) for supplying power to the first control unit (8) by operating the first control unit (8).

The lamp power supply step S53 is a step in which the first control unit 8 controls the lamp switch 73 to turn on the lamp 7 by closing the lamp power line. Therefore, even if power is not supplied to the dishwasher through the power input unit 51, the lamp 7 can be turned on only when the user opens the door 12, thereby allowing the user to easily store the dishes And the consumption of standby power can be minimized.

The power supplied to the lamp 7 can be progressed until the inlet 111 is closed by the door 12. [ The second control unit 9 determines whether the first sensor 61 and the second sensor 63 have closed the inlet 111 in the step S56 of determining whether the inlet 111 is closed by the door It is determined that the input port 111 is closed.

The first control unit 8 controls the lamp switch 73 so that the power supplied to the lamp 7 is supplied to the first control unit 8 And proceeds to the step S57 of cutting off the lamp power to be interrupted.

When the power supplied to the lamp is cut off, the second controller 9 controls the second power line switch 81 to cut off the power supplied to the first controller 8, .

When the steps S57 and S58 for cutting off the power supplied to the lamp and the first control unit are completed, the control method of the present invention will proceed only to the maintenance steps S11, S13 and S15.

Meanwhile, step S53 of supplying power to the lamp 7 may be set to be terminated when a predetermined reference time elapses after power is supplied to the lamp (S561).

The inlet 111 is opened without supplying power to the dishwasher through the power input unit 51 because the dishwasher is housed in the racks 171 and 173 or the tableware housed in the rack is taken out to the outside . Therefore, even if a signal for requesting power supply to the first load terminal is not input through the power input unit 51, lighting the lamp 7 when the input port 111 is opened allows the user to store or retrieve the tableware .

A situation in which the inlet 111 is not closed until a predetermined time elapses after the lamp 7 is turned on can be seen as opening of the door 12 which is not intended by the user, A failure of the door, a failure of the door, a user opening the door to ventilate the inside of the tub, etc.), the lamp 7 will be wasted.

Accordingly, the power supplied to the lamp 7 when the door is opened after the reference time has elapsed after the door is opened also has the effect of minimizing the consumption of standby power.

FIG. 4 illustrates another embodiment of the control method of the present invention. In the control method according to the present embodiment, a power supply request signal is transmitted through the power input unit 51 during the maintenance step S11, S13, and S15 (S20, primary power supply request signal checking step).

The step S20 of determining whether the power supply request signal is inputted determines whether the first control unit 8 receives power through the first power line 85 of the control unit opened and closed by the power input unit 51 .

When power is supplied through the power input unit 51, the control method of the present invention includes the steps of supplying power to the first control unit 8 (S31), supplying power to the control command input unit 53 (S32 ).

Although not shown in FIG. 4, when the power is supplied through the power input unit 51, the control method of the present invention will also proceed to supply power to the display unit 57. FIG.

When the first control unit 8 and the control command input unit 53 are supplied with electric power S31 and S32, the control method of the present invention determines whether or not the input port 111 is opened (S33) (S34) of supplying power to the lamp (7) when the lamp is opened.

Whether or not the input port 111 is opened S33 is detected by the second control unit 9 by detecting the signal transmitted by the first sensor 61 and the second sensor 63 and the input port 111 The second control unit 9 notifies the first control unit 8 via the communication unit 2 that the first control unit 8 can supply power to the lamp through the lamp switch 73 (S34).

However, the first control unit 8 may receive the electrical signals generated by the first sensor 61 and the electrical signals generated by the second sensor 63 directly. In this case, it is determined whether or not the input port 111 is opened (S33). That is, the first controller 8 controls the signals generated by the first sensor 61 and the second sensor 63 without passing through the second control unit and the communication unit It will proceed by detecting it directly.

In step S34, power is supplied to the lamp, and then the charging port is closed (S35) after power is supplied to the lamp. When the predetermined reference time elapses after the opening of the charging port is detected (S351) )do.

Whether or not the input port 111 is closed is determined by the second control unit 9 detecting the signal transmitted by the first sensor 61 and the second sensor 63 and the input port 111 is closed The second control unit 9 notifies the first control unit 8 via the communication unit 2 that the first control unit 8 cuts off the power supplied to the lamp through the lamp switch 73 do.

When the first control unit 8 is provided to receive the signal generated by the first sensor 61 and the signal generated by the second sensor 63 directly, it is determined whether the input port 111 is closed S33 will proceed by directly sensing the electrical signals generated by the first sensor 61 and the second sensor 63 without the first control unit 8 passing through the second control unit and the communication unit.

After completing the step S36 of interrupting the power supplied to the lamp, the present invention proceeds to step S37 of determining whether a control command is input through the control command input unit 53. [

The step S37 of judging whether or not the control command is inputted can be proceeded through whether or not the signal generated in the control command input part 53 is transmitted to the second control part 9. [

When a control command is input through the control command input unit 53, the present invention proceeds to step S38 of executing the input control command. The control command execution step S38 is a step in which when the second control unit 9 transmits a control command to the first control unit 8 through the communication unit 2, Can be proceeded by controlling the first load through the load switch (82).

When the execution of the input control command is completed, the control method of the present invention cuts off the power supplied to the first control unit 8 and the power supplied to the control command input unit 53 (S391, S393) S13, and S15.

If it is detected that the input port 111 is opened (S51) even though there is no input of the power supply request signal in the primary power supply request signal checking step S20, the second control unit 9 The first control unit power supply step S52 for supplying power to the first control unit 8 through the second power line switch 81 is performed.

When power is supplied to the first control unit S52, the first control unit 8 controls the lamp switch 73 to supply power to the lamp 7 (S53) .

During the lamp power supply step (S53), the control method of the present invention proceeds to step S54 (step S54) of checking whether the power supply request signal is input through the power input unit (S54) .

If it is determined that the power supply request signal is input while the lamp power supply step S53 is in progress, the control method of the present invention may include a control panel power supply step S55 for supplying power to the display unit 55 and the control command input unit 53 (S35, S351, S36, S37, S38, S391, and S393) are executed sequentially after confirming whether or not the input port is closed, the lamp power is cut off, and the inputted control command.

However, if it is determined that the power supply request signal is not inputted in the secondary power supply request signal checking step S54, the control method of the present invention may include a step S56 of determining whether the charging port is closed, S57) and the first controller power cutoff step (S58), and executes the maintenance steps (S11, S13, S15).

As in the embodiment of FIG. 3, the lamp power cutoff step S57 may be set such that the lamp is powered on even if the input port is not closed by the door, and then proceeds after the reference time elapses.
