Hereinafter, the operation of the notification system for controlling the pause of the dishwasher according to the exemplary embodiment of the present invention and the control method thereof in association with the apparatus for controlling the pause of the dishwasher according to the embodiment of the present invention configured as described above and the control method thereof The effect is explained in detail.

It is assumed that a user opens the door of the dishwasher, puts the dishes to be cleaned, and closes the door.

On the other hand, it is assumed that no voltage is yet supplied to the power supply means 103 from an external AC power source.

On the other hand, it is assumed that the water supply valve 121 for supplying the washing water to the dishwasher is closed.

In FIG. 3, S means step (STEP).

As shown in FIG. 3, when the user presses the power switch in step S1, an AC voltage of 220 V is output from the external AC power source to the power supply means 103. Then, a DC voltage of 5V is supplied from the power supply means 103 to the control means 101.

In step S2, the user inputs the washing course arbitrarily selected from among the soaking, strong, standard, and saving courses by using the key input means 105 that can input the entire washing stroke to the control means 101. The control means 101 stores the input washing course in the memory 133.

In step S3, the control means 101 determines whether the operation switch installed in the key input means 105 is turned on. As a result of this determination, when the control means 101 determines that the operation switch is turned on by the user (if YES), the processing proceeds to step S4.

In step S4, the control means 101 outputs a control signal to the water supply circuit 117 to open the water supply valve 121. In response to the control signal, the water supply circuit 117 outputs a driving signal to the water supply valve 121 to supply the washing water.

The water supply valve 121 is opened by the driving signal, and the washing water is supplied into the washing tank of the dish washing machine. The washing water supplied into the washing tank is supplied to the sump.

In step S5, the pressure of the washing water supplied into the washing tank is sensed by the water level sensor 111 installed below the washing tank. The frequency corresponding to the water level in the washing tank is output from the water level sensor 111 to the control means 101 by the detection of the water level sensor 111.

The control means 101 determines whether the water level in the washing tank is equal to the normal water level preset in the memory 133 by comparing the frequency output from the water level sensor 111 with the set frequency input to the memory 133. do.

As a result of this determination, when it is determined that the water level in the washing tank is equal to the normal water level preset in the memory 133 (if YES), the process proceeds to step S6.

In step S6, the control means 101 outputs a control signal to the water supply circuit 117 to close the water supply valve 121. In response to the control signal, the water supply circuit 117 outputs a driving signal to the water supply valve 121 to stop the supply of the washing water.

The water supply valve 121 is closed by the driving signal to stop the supply of the washing water into the washing tank of the dish washing machine. The wash water supplied into the wash bath is stored in the sump.

In the state where the washing water is stored in the sump, the control means 101 outputs a control signal to the water supply circuit 117 to drive the water supply pump 119. In response to the control signal, the water supply circuit 117 outputs a driving signal to the water supply pump 119 so that the washing water is sprayed onto the dishes through the nozzle guide.

The water supply pump 119 is driven by the driving signal, and the washing water is sprayed into the dishwasher to start the washing operation. Then proceed with the entered course.

In step S7, the control means 101 determines whether there is a pause signal for the user to pause the input course stroke while the input course is in progress. As a result of this determination, when the control means 101 determines that the user inputs a pause signal for pausing the input course stroke (if YES), the process proceeds to step S8.

In step S8, the control means 101 outputs a control signal for temporarily stopping driving to the heating circuit 113, the water supply circuit 117, the drain pump driving circuit 123, and the like. The heating circuit 113, the water supply circuit 117, the drain pump driving circuit 123, and the like are driven by the control signal to the heater 115, the water supply pump 119, the water supply valve 121, the pump 125, and the like. Outputs a drive signal to stop the operation. The heater 115, the feed water pump 119, the feed water valve 121, the pump 125, and the like stop operation by the driving signal.

In step S9, the control means 101 stops driving of the heater 115, the feed water pump 119, the feed water valve 121, the pump 125 and the like by the pause signal. Set T1 = 0 to save to memory and start counting. The set time of T0 is, for example, 60 minutes. The set time of T1 is, for example, 60 seconds.

In step S10, the control means 101 determines whether the operation switch is reapplied by the user within the set time of T1. If it is determined that the operation switch has not been reapplied as a result of this determination (step NO), the flow proceeds to step S11.

In step S11, the control means 101 determines whether time T1 has reached a preset time set in the memory 133. As a result of this determination, when it is determined that the time T1 is a preset time set in the memory 133 (if YES), the processing proceeds to step S12.

In step S12, when the control time 101 reaches the setting time of T1 = 60, the control means 101 increments 1 to T0 and stores it in the memory 133.

In step S13, when T1 = 60, the control means 101 outputs an acoustic signal to the sound generator 131 indicating that the washing operation is paused. The sound signal generates a warning sound informing the user of the pause state from the sound generator 131.

In step S14, the control means 101 determines whether time T0 has reached a preset time set in the memory 133. As a result of this determination, when it is determined that the time of T0 is a preset time set in the memory 133 (if YES), the processing proceeds to step S15.

In step S15, the control means 101 outputs a control signal for turning off the power to the power supply means 103. In response to the control signal, the power supply means 103 turns off the power to the control means 101 and the load means to terminate the washing operation.

On the other hand, when it is determined in step S3 that the operation switch installed in the key input means 105 is turned on in step S3, and it is determined that the operation switch is not turned on (if NO), the process goes to step S2. Proceed.

Meanwhile, in step S5, the control unit 101 compares the frequency output from the water level sensor 111 with the set frequency input to the memory 133, and the water level in the washing tank is normally set in the memory 133 in advance. If it is determined that the water level is equal to the water level, and it is determined that the water level in the washing tank is not equal to the normal water level preset in the memory 133 (if NO), the flow advances to step S4.

On the other hand, when the user determines whether there is a pause signal for pausing the input course stroke while the course is being input in step S7, and if it is determined that there is no pause signal for pausing (if NO Proceeds to step S16.

In step S16, the control means 101 determines whether all course administration has been completed. As a result of this determination, when the control means 101 determines that all course administration has been completed (if YES), the process proceeds to step S17.

When all the course stroke is completed in step S17, the control means 101 outputs a control signal to automatically cut off the voltage supplied to the load, such as the water supply valve 121, the water supply pump 119 and the heater 115 . Power is automatically turned off by the control signal.

On the other hand, in step S10, the control means 101 determines whether the operation switch is turned on again by the user during the set time of T1, and as a result, the control means 101 is applied again by the user. If it is determined that it is turned on (YES), the flow proceeds to step S18.

In step S18, the control means 101 outputs the remaining washing stroke from the memory 133 to proceed with the remaining washing stroke.

On the other hand, in step S11, the control means 101 determines whether time T1 has reached the preset time set in the memory 133, and as a result, the time T1 has not reached the preset time set in the memory 133. If it is determined (NO), the flow proceeds to step S10.

On the other hand, in step S14, the control means 101 determines whether T0 has reached the preset time set in the memory 133, and has determined that T0 has not reached the preset time set in the memory 133. If NO (NO), the process proceeds to step S10.

On the other hand, if it is determined in step S16 that all the course strokes have been completed, the control means 101 determines that all the course strokes have not been completed (if NO), and the flow advances to step S6.

When the user pauses during the washing stroke, the alarm sounds every set time, so that the user can recognize that the washing stroke is paused.
