  By the way, in a dishwasher equipped with an electrolyzed water generator equipped in a dishwasher, or a dishwasher connected to an electrolyzed water generator and a wash water tank separately from the dishwasher via a supply line If the electrolysis operation of the electrolyzed water generating device is set to be performed synchronously with the washing operation of the dishwasher, the electrolyzed alkaline water in the wash water tank even after the rinsing step is completed. Supply to will continue. For this reason, the electrolytically generated alkaline water that is continuously supplied is supplied into the washing water tank, but a portion of the supplied electrolytically generated alkaline water is discharged directly through the overflow pipe. In the electrolyzed water generating apparatus that generates electrolyzed alkaline water that cannot be effectively used as a cleaning agent and cannot be used effectively, the electrolyzed water generating apparatus takes a long time for electrolysis and is disposed in a diaphragm electrolyzer. As a result, the load on each electrode is increased, and the life of each electrode is shortened early.

  Further, in the electrolyzed water generating apparatus, at the start of electrolysis operation, if an attempt is made to quickly set the electrolysis current to the set current value by applying a voltage between the electrodes of each electrolysis chamber constituting the diaphragm electrolyzer, However, the electrolytic current value may exceed the set current value. This phenomenon causes a heavy load on each electrode and shortens the life of each electrode at an early stage. For this reason, as the number of times of electrolytic operation increases, a large load is repeatedly applied to each electrode. In this case, the life of each electrode is remarkably shortened.

  Therefore, in the electrolyzed water generating apparatus, electrolysis operation is performed by looking at the optimal timing such as the washing process and the rinsing process in the washing operation of the dishwasher, and the electrolyzed alkaline water is supplied into the washing water tank without waste. Thus, it is necessary to reduce the time of electrolysis operation of the electrolyzed water generating apparatus and reduce the number of electrolysis operations. An object of the present invention is to address such problems.

  The present invention relates to a dishwasher using electrolytically generated alkaline water as washing water. A dishwasher to which the present invention is applied is a dishwasher using electrolytically generated alkaline water generated by a diaphragm electrolysis type electrolyzed water generating device as cleaning water, and is supplied into a cleaning water tank. Tableware having a washing process using electrolytically generated alkaline water diluted with water contained in a washing water tank as washing water, and a rinsing process using water contained in the rinsing water tank as rinsing water It is a washing machine.

  Therefore, the first dishwasher according to the present invention is a dishwasher of the above-described type, and in the dishwasher, the number of times of operation of the rinse pump for supplying the rinse water to the rinsing process is set. When the predetermined number of times is reached, the electrolyzed water generating apparatus is electrolyzed for a predetermined time, and during this time, a predetermined amount of electrolyzed alkaline water is supplied into the washing water tank.

  Moreover, the 2nd dishwasher which concerns on this invention is a dishwasher of the above-mentioned type, Comprising: In the said dishwasher, the operation time of the rinse pump which supplies a rinse water to the said rinse process was set. When the time is reached, the electrolyzed water generating device is electrolyzed for a predetermined time, and during this time, a predetermined amount of electrolyzed alkaline water is supplied into the washing water tank.

  The third dishwasher according to the present invention is a dishwasher of the above-described type, and the electrolyzed water generating device is set at the start of operation of a washing pump that supplies washing water to the washing step. Electrolytically generated alkaline water is supplied for a predetermined amount into the washing water tank during this time electrolysis operation.

  In the dishwasher according to the present invention, during the washing operation of the dishwasher, strong alkaline electrogenerated alkaline water generated by the electrolyzed water generator is supplied into the wash water tank, and the wash water tank It can mix with the water (washing water, rinse water, etc.) accommodated and dilute, and the washing water containing a cleaning agent can be prepared. Thereby, the washing | cleaning function of the electrolyzed alkaline water produced | generated with an electrolyzed water production | generation apparatus can be utilized effectively with respect to a to-be-cleaned object.

  Thus, in the first dishwasher according to the present invention, when the electrolysis operation of the electrolyzed water generating apparatus reaches the predetermined number of times that the number of times of operation of the rinse pump that supplies the rinse water to the rinsing process is set. The electrolytically generated alkaline water is supplied for a predetermined amount into the washing water tank during this time. For this reason, compared with the case where the electrolysis operation of the electrolyzed water generator is made synchronously with the wash operation of the dishwasher, the number of electrolysis operations of the electrolyzed water generator during the wash operation of the dishwasher is reduced. Can do.

  As a result, it is possible to greatly reduce the load on each electrode in each electrolysis chamber constituting the diaphragm membrane electrolytic cell of the electrolyzed water generating device, and to greatly improve the life of each electrode. However, the number of times of electrolysis operation is set according to the degree to which strongly alkaline electrolyzed alkaline water is diluted with water in the washing water tank, and the washing function is equivalent even when diluted with water in the washing water tank. One criterion is to be demonstrated to the extent.

  Further, in the second dishwasher according to the present invention, when the electrolysis operation of the electrolyzed water generating apparatus reaches a predetermined time in which the operation time of the rinse pump that supplies the rinse water to the rinsing process is set. The electrolytically generated alkaline water is supplied for a predetermined amount into the washing water tank during this time. For this reason, compared with the case where the electrolysis operation of the electrolyzed water generator is made synchronously with the wash operation of the dishwasher, the number of electrolysis operations of the electrolyzed water generator during the wash operation of the dishwasher is reduced. Can do. As a result, it is possible to greatly reduce the load on each electrode in each electrolysis chamber constituting the diaphragm membrane electrolytic cell of the electrolyzed water generating device, and to greatly improve the life of each electrode.

  Further, in the third dishwasher according to the present invention, the electrolysis operation of the electrolyzed water generating device is continued for a predetermined time set at the start of operation of the cleaning pump that supplies the cleaning water to the cleaning step. During this time, a predetermined amount of electrolytically generated alkaline water is supplied into the washing water tank. At the start of the operation of the washing pump, the level of the washing water in the washing tank in the full tank state is instantaneously lowered, and the lowered state of the water level is continued during the washing operation. For this reason, the supply of electrolyzed alkaline water into the wash water tank with a lowered wash water level does not drain the electrolyzed alkaline water supplied directly from the overflow pipe. And can be supplied into the washing water tank.

  The dishwasher according to the present invention is a dishwasher that uses electrolytically generated alkaline water generated by an electrolyzed water generating apparatus of the diaphragm electrolysis type as cleaning water. FIG. 1 schematically shows an embodiment of a dishwasher according to the present invention. The dishwasher according to the embodiment uses a diaphragm electrolysis-type electrolyzed water generator installed in the kitchen independently of the dishwasher itself, and the dishwasher itself uses a dedicated electrolyzed water generator. Compared to the dishwasher equipped, it is inexpensive and easy to use without impeding the use of each electrolyzed water produced by the electrolyzed water producing device in a wide field.

  The dishwasher is housed in a rinsing water tank with a washing process using electrolytically generated alkaline water diluted with water (washing water, rinsing water, etc.) contained in the washing water tank, and the rinsing water tank. It has a rinsing process using water as rinsing water.

  The dishwasher A shown in FIG. 1 is connected to an electrolyzed water generating device B of a diaphragm electrolysis type that is installed independently, and is connected to the electrolyzed water generating device B, and electrolyzed water is generated. Except for the operation control relationship with the apparatus B, the configuration itself is known. Moreover, the electrolyzed water generating apparatus B is also known per se.

  The dishwasher A includes a washing water tank 11 at the bottom of the washing chamber formed in the case body, and a washing nozzle 12 is disposed above the washing water tank 11 at a predetermined height, and a rinsing nozzle 13 is disposed above the washing nozzle 12. A storage shelf 14 for storing tableware is installed between the cleaning water tank 11 and the cleaning nozzle 12. Moreover, the said dishwasher A is provided with the booster 15 installed outside the case main body.

  The washing water tank 11 constituting the dishwasher A is provided with an overflow pipe 11b in the tank body 11a, and a water level sensor 11c is disposed on the side of the tank body 11a. The cleaning water stored in the cleaning water tank 11 is used in the cleaning process, and the strongly alkaline electrolytically generated alkaline water supplied from the electrolytic water generator B is stored in the cleaning water tank 11. It is prepared by diluting with water (washing water, rinsing water, etc.). In the washing water tank 11, the set predetermined volume of washing water is accommodated by the action of the overflow pipe 11b and the water level sensor 11c, and is maintained at the set predetermined water level.

  The overflow pipe 11b penetrates the bottom of the tank body 11a in a liquid-tight manner so that it can be inserted and removed, and is inserted into a cover pipe 11d erected on the bottom of the tank body 11a. For this reason, when the washed water stored in the washing water tank 11 is drained, the overflow pipe 11b is pulled out from the bottom of the tank body 11a.

  The booster 15 is a kettle-type rinse water tank, and includes a heater at the bottom inside the tank. Tap water is supplied into the booster 15 through a water supply valve 24, which will be described later, and the water supplied into the booster tank 15 is heated when the water level becomes a certain level or higher, and has a predetermined temperature set. It becomes warm water.

  In the operation of the cleaning process in the dishwasher A, the cleaning pump 16 is operated. The cleaning water in the cleaning water tank 11 is supplied to the cleaning nozzle 12 through the supply pipe 21 by the operation of the cleaning pump 16 and is jetted from the cleaning nozzle 12. The sprayed cleaning water cleans the tableware stored in the storage shelf 14 and falls into the tank body 11a of the cleaning water tank 11 after cleaning. The cleaning pump 16 circulates cleaning water through the supply pipe 21 and the cleaning nozzle 12 for a predetermined time, and promotes cleaning of the dishes in the storage shelf 14 during this period. In the embodiment of the dishwasher according to the present invention, the operation of the rinsing process is performed following the end of the operation of the cleaning process. The cleaning operation is controlled by a control device (not shown).

  In the operation of the rinsing process in the dishwasher A, the rinsing water (warm water) accommodated in the booster 15 is supplied to the rinsing nozzle 13 through the supply pipe 22 by the operation of the rinsing water pump 17, and the rinsing nozzle. 13 is injected. The rinse water sprayed from the rinse nozzle 13 rinses and cleans the cleaned dishes stored in the storage shelf 14, and then drops into the tank body 11 a of the cleaning water tank 11 and is stored.

  In the tank main body 11a, as the rinse water falls, the existing washed water in the tank main body 11a is sequentially drained through the overflow pipe 11b in accordance with the amount of rinse water to be accommodated. After the end of the operation, the inside of the tank body 11a is substantially replaced with rinsing water. Note that tap water is used as the rinsing water, and the tap water is supplied into the booster 15 by opening a water supply valve 24 provided in the middle of the water supply pipe 23. The opening / closing control of the water supply valve 24 is controlled by a control device (not shown).

  The washing water in the dishwasher A is prepared by performing an electrolysis operation of the electrolyzed water generator B. The electrolysis operations in the first, second, and third dishwashers according to the present invention will be described later. Thus, according to the condition of the washing operation of the dishwasher A, it is performed at different timings. The electrolyzed water generator B is known per se, and employs an existing electrolyzed water generator installed independently of the dishwasher A.

  In the electrolyzed water generating apparatus B, a flow switching valve 25 (three-way valve) is provided in a dedicated outlet pipe 31 for deriving electrolytically generated alkaline water generated in the cathode side electrolysis chamber constituting the diaphragm membrane electrolytic cell. ) Is connected to the introduction pipe 26 extending above the washing tank 11 of the dishwasher A and the outlet pipe 32 for draining the electrolytically generated alkaline water or draining it.

  Thereby, the strongly alkaline electrolytically generated alkaline water generated in the diaphragm membrane electrolytic cell is selectively supplied to the outlet conduit 35 side and the inlet conduit 25 side by the switching operation of the passage switching valve 25. In addition, an introduction conduit 34 that faces the upper side of the sink C is connected to a dedicated outlet conduit 33 that leads out the electrolytically generated acidic water generated in the anode-side electrolytic chamber constituting the diaphragm membrane electrolytic cell.

  FIG. 2 shows a flowchart for executing the operation control program for the washing operation of the first dishwasher of the present invention, and FIG. 3 shows a flowchart for executing the operation control program for the rinse water preparation operation. FIG. 4 shows a flowchart for executing the operation control program of the electrolysis operation of the electrolyzed water generator B. In the first dishwasher, the washing operation (washing process operation and rinsing process operation) of the dishwasher A and the electrolysis operation of the electrolyzed water generator B are controlled by a control device (not shown).

  The control apparatus with which the 1st tableware washing machine which concerns on this invention equips is based on the instruction | indication of washing | cleaning operation, and performs an operation control program based on the flowchart shown in FIG. In step 101, the control device determines whether or not a full water signal is output from the booster. If not, the control device waits for a predetermined time (step 102). After confirming the output of the full water signal, step 103. Then, it is determined whether or not the water level in the washing water tank 11 is sufficient. If the water level in the washing water tank 11 is not sufficient, the rinsing water pump 17 is operated (step 104), and the control program is executed. To step 101.

  When it is determined that the level of the cleaning water in the cleaning tank 11 is sufficient, the control device determines in step 105 whether or not the switch for instructing the cleaning operation is ON, and when the switch is not ON. Returns the control program to step 101, and when it is determined that the switch is ON, the cleaning pump 16 is operated to start the cleaning process (step 106), and the cleaning process has been operated for a predetermined time. The operation is stopped at the time, and the rinse water pump 17 is driven to start the operation of the rinsing process (step 107). The control device stops the operation when a predetermined time elapses during the rinsing process, and returns the operation control program to Step 101 after the stop.

  In the meantime, in the booster 15, the operation control program of the rinse water preparation operation is executed based on the flowchart shown in FIG. In step 201, the control device determines whether or not the water level in the booster tank 15 is sufficient. If the water level is not sufficient, the control device opens the water supply valve 24 and waits for water supply (step 202). If it is determined that the water level is sufficient, a full water signal is output (step 203).

  Thereafter, in step 204, the control device determines whether or not the water temperature in the booster tank 15 has reached the set temperature. If the temperature is lower than the set value, the controller heats the water in the booster tank 15. (Step 205), the operation control program is returned to Step 201. When it is determined in step 204 that the water temperature in the booster tank 15 has reached the set temperature, the control device returns the operation control program to step 201.

  On the other hand, in the electrolysis operation of the electrolyzed water generator B, the control device executes the operation control program based on the flowchart shown in FIG. In step 301, the control device determines whether or not the water level in the washing water tank 11 is sufficient. If the water level is sufficient, the control device detects the operation signal of the rinse water pump 17 in step 302 and When the number of operations is counted and the number of operations of the rinse water pump 17 reaches a predetermined number of times, the electrolysis operation of the electrolyzed water generating device B is started in step 303 and the operation of the rinse water pump 17 is performed. Clear count and reset.

  Simultaneously with the start of operation of the electrolyzed water generator B, the control device cuts the full water signal of the booster 15 output from the booster 15 to the dishwasher A, and continues the electrolysis operation for a predetermined time. However, the full signal of the booster 15 is not cut when the cleaning pump 16 is operated. In step 304, the control device continues the electrolysis operation for a predetermined time, stops the electrolysis operation when the electrolysis operation elapses for a predetermined time, and outputs a full water signal of the booster 15 output from the booster 15 to the dishwasher A. The cut is canceled (step 305). Thereafter, the control device stops the electrolysis operation of the electrolyzed water generating device B (step 306), and returns the control program of the electrolysis operation to step 301.

  In the electrolysis operation of the electrolyzed water generator B, for example, the number of operations of the rinse pump 17 is set to 3 times, and the electrolysis operation is started when the number of operations of the rinse pump 17 becomes 3, and the electrolysis operation is performed 3 Continue for a minute. Since the supply flow rate of the electrolyzed alkaline water in the electrolysis operation is 1 L / min, the supply amount of the electrolyzed alkaline water in the electrolysis operation into the cleaning tank 11 is 3 L.

  In the electrolysis operation, diaphragm electrolysis using dilute saline as electrolyzed water is performed, and strongly alkaline electrogenerated alkaline water is generated in the cathode side electrolysis chamber of the diaphragm electrolyzer constituting the electrolyzed water generator B. The The generated electrolytically generated alkaline water is supplied into the cleaning water tank 11 through the lead-out conduit 31 dedicated to the electrolytically generated alkaline water connected to the cathode side electrolytic chamber and the inlet conduit 26. The inside of the washing water tank 11 is filled with washing water and / or rinsing water, and the supplied electrolytically generated alkaline water is mixed with washing water and / or rinsing water in a full water state to dilute washing. The washing water is prepared by supplementing the agent (electrolytically generated alkaline water) and sufficiently restoring the washing function.

  In the dishwasher, when the washing water tank 11 is not filled with washing water during the washing operation, the rinse water pump 17 is operated so that the washing water tank 11 is filled with water, Rinsing water is supplied from the booster 15 into the washing water tank 11. In this case, in the operation control of the electrolysis operation, the control device determines in step 301 that the water level in the wash water tank 11 is not sufficient, and advances the operation control program to step 303. While starting the electrolysis operation of the production | generation apparatus B, the count of the frequency | count of the operation of the rinse water pump 17 is cleared and reset. Thereafter, the control device continues the electrolytic operation for a predetermined time, supplies a predetermined amount of electrolyzed alkaline water into the cleaning water tank 11, and fills the cleaning water tank 11 with cleaning water having a sufficient cleaning function. To.

  As described above, in the first dishwasher according to the present invention, the electrolysis operation of the electrolyzed water generating apparatus B is performed when the number of times of operation of the rinse water pump 17 that supplies the rinse water to the rinse process reaches the set number of times. It starts and continues for a predetermined time. During this period, a predetermined amount of electrolytically generated alkaline water is supplied into the wash water tank 11.

  Therefore, compared with the case where the electrolysis operation of the electrolyzed water generator B is performed synchronously with the washing operation (washing step and rinsing step) of the dishwasher A, the electrolysis operation time can be greatly reduced, The number of electrolysis operations of the electrolyzed water generating apparatus during the cleaning operation of the dishwasher A can also be reduced. As a result, the load on each electrode of each electrolysis chamber constituting the diaphragm membrane electrolytic cell of the electrolyzed water generating apparatus B can be greatly reduced, and the life of each electrode can be greatly improved.

  In the second dishwasher according to the present invention, the electrolysis operation of the electrolyzed water generator B is started when the operation time of the rinse water pump 17 that supplies the rinse water to the rinsing process reaches the set time. The electrolytically generated alkaline water is supplied into the washing water tank 11 for a predetermined time.

  The flowchart for executing the operation control program for the washing operation of the second dishwasher according to the present invention and the flowchart for executing the operation control program for the preparation operation for rinsing water are the same for the first dishwasher. This is the same as the flowchart for executing these operation control programs. FIG. 5 shows a flowchart for executing the operation control program for the electrolytic operation of the second dishwasher according to the present invention.

  As in the case of the first dishwasher, the control device provided in the second dishwasher according to the present invention executes the operation control program based on the washing operation command based on the flowchart shown in FIG. The operation control program for the water preparation operation is executed based on the flowchart shown in FIG. Moreover, a control apparatus performs the operation control program of the electrolysis operation in the said electrolyzed water generating apparatus B based on the flowchart shown in FIG.

  When executing the operation control program for the electrolysis operation of the electrolyzed water generating apparatus B, the control device first determines whether or not the water level in the wash water tank 11 is sufficient in step 311 and is sufficient. In some cases, the operation time of the rinse water pump 17 is detected, the operation time is added to the counters D and E (step 312), and the counter D reaches a predetermined time (step 313). In Step 314, the electrolysis operation of the electrolyzed water generator B is started, the counter D is reset, and the full water signal of the booster 15 output from the booster 15 to the dishwasher A is cut. However, the full signal of the booster 15 is not cut when the cleaning pump 16 is operated.

  Thereafter, the control device continues the electrolysis operation for a predetermined time (315), and determines whether or not the counter E has reached the predetermined time set in step 316 when the electrolysis operation has elapsed for a predetermined time. When it is determined in step 316 that the counter E has not reached the predetermined time set in step 316, the control device stops the electrolysis operation of the electrolyzed water generating device B in step 317 and the tableware is supplied from the booster 15. The cut of the full water signal of the booster 15 output to the washing machine A is canceled, and the operation control program is returned to step 311.

  The counter D in the electrolysis operation is a predetermined time in which the operation time of the rinse pump 17 is set, and is set to 18 seconds, for example, and the electrolysis operation time is set to 3 minutes, for example. Since the operation time per rinse pump 17 is 8 seconds, the supply amount of the electrolyzed alkaline water in the washing tank 11 in the electrolysis operation is 3L.

  In addition, when it is determined in step 316 that the counter E has reached the predetermined time, the control device extends the electrolytic operation for the predetermined time (step 318), and then the electrolyzed water generating device. The electrolytic operation of B is stopped, the cut of the full signal of the booster 15 output from the booster 15 to the dishwasher A is canceled, and the operation control program is returned to step 311. If it is determined in step 311 that the water level in the wash water tank 11 is not sufficient, the control device resets the counter E (step 319) and advances the operation control program to step 312.

  The counter E in the electrolysis operation is an integrated value of the operation time of the rinse pump 17 after the end of the initial hot water supply, and is set to, for example, 300 seconds in the electrolysis operation. The counter E serves as a standard for knowing a decrease in the cleaning power of the cleaning water stored in the cleaning tank 11. In the dishwasher A, when the number of times of operation of the rinse pump 17 is about 50 times, the cleaning water stored in the cleaning tank 11 reduces its cleaning power due to contamination. In the electrolysis operation, in order to cope with this, when the integrated value of the operation time of the rinse pump 17 reaches 300 seconds, the operation time per operation of the rinse pump 17 is extended by a predetermined time, and the electrolysis generated alkalinity is increased. The supply amount of the water into the cleaning tank 11 is increased by a predetermined amount to compensate for the decrease in the cleaning power of the cleaning water.

  In the electrolysis operation, diaphragm electrolysis using dilute saline as electrolyzed water is performed, and strongly alkaline electrolyzed alkaline water is generated in the cathode side electrolysis chamber of the diaphragm electrolyzer constituting the electrolyzed water generator B. The The generated electrolytically generated alkaline water is supplied into the cleaning water tank 11 through the lead-out conduit 31 dedicated to the electrolytically generated alkaline water connected to the cathode side electrolytic chamber and the inlet conduit 26. The inside of the washing water tank 11 is filled with washing water and / or rinsing water, and the supplied electrolytically generated alkaline water is mixed with the washing water and / or rinsing water in a full water state to dilute washing. A washing water having a sufficient washing function is prepared by supplementing the agent (electrolytically generated alkaline water).

  Thus, in the second dishwasher according to the present invention, the electrolysis operation of the electrolyzed water generator B is performed for a predetermined time (counter) in which the operation time of the rinse water pump 17 that supplies the rinse water to the rinse process is set. D) is started when the temperature reaches D) and continues for a predetermined time. During this period, a predetermined amount of electrolytically generated alkaline water is supplied into the washing water tank 11. Therefore, compared with the case where the electrolysis operation of the electrolyzed water generator B is performed synchronously with the wash operation of the dishwasher A, the number of electrolysis operations of the electrolyzed water generator during the wash operation of the dishwasher A is reduced. can do. As a result, the load on each electrode of each electrolysis chamber constituting the diaphragm membrane electrolytic cell of the electrolyzed water generating apparatus B can be greatly reduced, and the life of each electrode can be greatly improved.

  Further, in the third dishwasher according to the present invention, the electrolysis operation of the electrolyzed water generating apparatus B is started during the operation of the cleaning pump 16 that supplies the cleaning water to the cleaning process, and continues for a predetermined time. A predetermined amount of generated alkaline water is supplied into the washing water tank 11. Note that the flowchart for executing the operation control program for the washing operation of the third dishwasher and the flowchart for executing the operation control program for the rinse water preparation operation are those for the first dishwasher. It is the same as the flowchart. FIG. 6 shows a flowchart for executing the operation control program for the electrolytic operation of the third dishwasher according to the present invention.

  As in the case of the first dishwasher, the control device provided in the third dishwasher according to the present invention executes the operation control program based on the flowchart shown in FIG. The operation control program for the water preparation operation is executed based on the flowchart shown in FIG. Moreover, a control apparatus performs the operation control program of the electrolysis operation of the said electrolyzed water generating apparatus B based on the flowchart shown in FIG.

  When executing the operation control program for the electrolysis operation of the electrolyzed water generator B, the control device first detects the operation signal of the rinse water pump 17 in step 321 and then in step 322 the washing water tank. It is determined whether the water level in 11 is sufficient. When it is determined that the water level in the washing water tank 11 is not sufficient, the control device starts electrolysis operation of the electrolyzed water generating device B in step 323 and is output from the booster 15 to the dishwasher A. The boost signal of the booster 15 is cut and the electrolytic operation is continued for a predetermined time. However, the full signal of the booster 15 is not cut when the cleaning pump 16 is operated.

  The control device continues the electrolytic operation for a predetermined time (step 324), stops the electrolytic operation when the predetermined time has elapsed, and cancels the cut of the full signal of the booster 15 output from the booster 15 to the dishwasher A. (Step 325) and the control program of the electrolysis operation is returned to Step 321. In the electrolysis operation, the electrolysis operation is continued for 1 minute, for example.

  In the control of the electrolytic operation, for example, when the cleaning water tank 11 is empty before the cleaning process operation, the electrolytic operation is performed in the cleaning water tank 11 to prepare cleaning water having a cleaning function, The level of the cleaning water in the cleaning water tank 11 is made sufficient. In this state, the control device determines in step 322 that the water level in the cleaning water tank 11 is sufficient, detects the operation signal of the cleaning pump 16 in step 326, and sets the operation control program to step 323. Proceed. In Step 323, the control device starts electrolysis operation of the electrolyzed water generating device B and advances the operation control program to Steps 324 and 325 to wash the electrolyzed alkaline water generated by the electrolyzed water generating device B with a washing water tank. A predetermined amount is supplied into the inside 11.

  As described above, in the third dishwasher according to the present invention, the electrolysis operation of the electrolyzed water generating apparatus B is started during the operation of the cleaning pump 16 that supplies the cleaning water to the cleaning process, and continues for a predetermined time. The electrolytically generated alkaline water is supplied into the washing water tank 11 in a predetermined amount. At the start of the operation of the cleaning pump 16, the water level of the cleaning water in the cleaning water tank 11 in a full tank state is instantaneously lowered, and the lowered state of the water level is maintained during the cleaning operation. For this reason, the supply of the electrolyzed alkaline water into the wash water tank 11 in which the water level of the wash water has decreased is such that the supplied electrolyzed alkaline water is not directly drained from the overflow pipe 11b, and the electrolyzed alkaline water is supplied. Water can be supplied into the washing water tank 11 without waste.
