Hereinafter, the operation of the present invention will be described in detail with reference to the accompanying drawings. 3 is a flowchart for explaining the main operation of the present invention.

As shown, in step S301 the user through any one of the control tube 123 or the one key input unit 221 provided on one side of the housing 125 provided in each of the storage tube (101,103) Perform keystrokes to control sequential cleaning of one or two receiving tubes. Accordingly, the control unit 201 patches the washing control algorithm corresponding to the washing mode from the program memory 219. For example, the control algorithm mounted in the program memory 219 may be a first washing mode in which dishes are seated in the first storage tube 101 or a dish for washing dishes in the second storage tube 103. A washing algorithm corresponding to the third washing mode for washing both dishes in the second washing mode or the first receiving tube 101 and the second receiving tube 103 is included.

From this, the control unit 201 recognizes the washing mode provided by the key input unit 221. That is, the control unit 201 enters the step S303 to determine whether the first washing mode, the determination result is the first washing mode, that is, if you want to wash the dishes in the first receiving tube 101 to step S305 The heater 209 is started to enter. Thereafter, the controller 201 determines whether the current washing water temperature is a preset temperature T1. The set temperature is the temperature of the washing water for dish washing seated on the first receiving tube 101, and may be set by the user according to the type of the dish. Accordingly, the plurality of types of set temperatures T1, T2, T3, and T4 described below may be the same temperature, and may be set by the user as needed.

When the temperature of the washing water currently detected does not reach the preset temperature T1, the controller 201 enters the step S305 to continuously operate the heater. On the other hand, when the set temperature T1 is reached, the process proceeds to step S309 and the control unit 201 selectively controls the three-way water supply valve 205. This is a valve control for supplying the currently provided washing water to the first receiving tube 101 or the second receiving tube 103, the control unit 201 is currently set to the first cleaning mode, the first receiving tube Valve control (A) is performed so that the washing water is supplied to 101. After that, the control unit 201 enters the step S311 for spraying the pre-heated washing water to the three-way water supply valve 205 by starting the pump 207, and performs the corresponding process for a predetermined time in step S313.

On the other hand, if the washing mode recognized by the control unit 201 in step S303 is not the first washing mode, it is determined whether the second washing mode. Here, when the control unit 201 recognizes the second washing mode, the control unit 201 enters the step S317 to start the heater 209. As described above, the control unit 201 determines in step S319 whether the washing water temperature T2 input from the key input unit 221 is reached using a temperature sensor provided inside the heater 209. . If the current wash water temperature does not reach the preset temperature T2, the process proceeds to step S317 to continuously operate the heater 209 to increase the temperature of the wash water.

On the other hand, when it is determined in the step S319, when the set temperature (T2) is reached, the control unit 201 switches the three-way water supply valve 205 to the 'B' state to wash water to the second receiving tube Control to be supplied to (103). This is based on the algorithm of the program memory 219 according to the second wash mode. In addition, as a result of the determination in step S315, if it is not the second washing mode, the controller 201 enters the step S323 and determines whether the current washing mode is the third washing mode.

As a result of the determination, when the control mode is not the third washing mode, the control unit 201 outputs an error message for setting the washing mode by feeding back to the step S301 and induces a reset of the washing mode. If it is recognized as the washing mode and enters the step S325, the control unit 201 controls the rise of the temperature of the washing water by starting the heater 209. Thereafter, the control unit 201 determines whether the preset set temperature T3 is reached by measuring the current washing water temperature in step S327. As a result of determination, when the set temperature (T3) is not reached, the heater 209 is continuously operated to increase the temperature of the washing water. As a result of the determination in step S329, the current washing water temperature is set to the preset setting temperature (T3). When reaching, the control unit 201 controls the three-way water supply valve 205 in step S329. This is to set the washing order for washing the dishes of the first storage tube 101, after washing the dishes of the first storage tube 101 according to the third cleaning mode, the first embodiment of the present invention The dishwashing of the storage tube 101 is preceded.

Therefore, the control unit 201 sets the three-way water supply valve 205 in the 'A' direction to supply the currently heated washing water to the first receiving tube 101. This is the injection is made through step S331, so that the washing is made for a predetermined washing time in step S333. Of course, this cleaning time may be set by the user.

As described above, in step S333, the controller 201 recognizes a predetermined washing time and then performs washing water heating to wash the dishes of the second receiving tube 103. That is, in step S335, the control unit 201 starts the heater 209 again, and enters step S337 to determine whether the current washing water reaches the set temperature T4 set by the user. In the same way, if the current washing water does not reach the set temperature (T4) to feed back to the step S335 to perform a continuous heating operation of the heater 209.

On the other hand, if it is recognized in step S337 that the current wash water temperature has reached the set temperature (T4), the control unit 201 switches to the 'B' state by controlling the three-way water supply valve 205. This is for supplying the washing water to the second receiving tube 103, the injection is made through step S341. After that, in step S343, the control unit 201 determines whether the current washing water injection is performed for a predetermined time and ends the washing operation.
