  By the way, the dishwashers proposed in each of the above-mentioned patent documents are all provided with an electrolyzed water generator dedicated to the dishwasher, and the electrolyzed water generator is expensive. As a result, the dishwasher integrated with the electrolyzed water generating device is expensive. For this reason, although the dishwasher integrally equipped with the dedicated electrolyzed water production | generation apparatus is useful, it is the present condition that it has not yet spread.

  On the other hand, in recent years, the electrolysis generator itself has become sufficiently widespread, and installed in a kitchen or the like independently from a dishwasher, the electrolyzed acidic water produced by the electrolyzed water generator is not limited to various types. A large amount of electrolytically generated alkaline water is used for sterilizing and cleaning foodstuffs and tableware, and is generated by the electrolyzed water generator, but as a wash water for cleaning contaminants such as foodstuffs and tableware. May be used.

  The present invention is less used in the electrolyzed water produced by the electrolyzed water producing device installed and used independently from the dishwasher as described above, and compared with the electrolyzed acidic water. The amount of water used is low, or it is made by paying attention to the electrolytically generated alkaline water that is drained without being used, and its purpose is to use the electrolytically generated alkaline water generated by the electrolytic water generating device, The purpose is to eliminate the use of washing water, which is an aqueous solution of a general-purpose detergent, so that it can be used as washing water for a dishwasher installed independently of the electrolyzed water generator. In particular, the present invention has a cleaning function for cleaning water prepared in a cleaning tank in consideration of the introduction into the cleaning tank of electrolytically generated alkaline water that is effectively used as a detergent in the dishwasher having such a configuration. The purpose is to further improve.

  The present invention relates to a dishwasher using electrolytically generated alkaline water as washing water. A dishwasher to which the present invention is applied has a washing process using electrolytically generated alkaline water contained in a washing tank as washing water, and a rinsing process using water contained in the rinsing tank as rinsing water. And a washing step using the electrolytically generated alkaline water contained in the washing tank as washing water and a rinsing step using the water contained in the rinsing tank as rinsing water, It is a dishwasher which starts the washing process after confirming that the rinsing water and the washing water in the washing tank are sufficient, and starts the rinsing process after completion of the washing process.

  Therefore, the first dishwasher according to the present invention is configured to wash the electrolytically generated alkaline water generated in the diaphragm membrane electrolytic cell of the electrolyzed water generating device installed independently of the dishwasher with the washing tank. Introducing a dedicated conduit for electrolytically generated alkaline water to be introduced into the interior, and diluting strongly alkaline electrolytically generated alkaline water introduced into the washing tank with rinse water introduced into the washing tank in the rinsing step The introduction of strong alkaline electrolytically generated alkaline water into the cleaning tank is started in response to the start of the rinsing step, and after a predetermined time has elapsed, the electrolytically generated alkaline Basically, the introduction of water into the washing tank is stopped, and the temperature of the washing water in the washing tank is equal to or higher than a set value and constant after electrolytically generated alkaline water is introduced. If it is passed between is characterized in that additionally injecting a predetermined amount of electrolyzed alkaline water into the washing tank.

  The second dishwasher according to the present invention has the same configuration as the first dishwasher according to the present invention, and the introduction of strong alkaline electrogenerated alkaline water into the cleaning tank is the rinse. It is started at the start of the process, and after a predetermined time has elapsed, the introduction of electrolytically generated alkaline water into the cleaning tank is basically stopped. A predetermined amount of electrolytically generated alkaline water is additionally introduced into the tank.

  In the first and second dishwashers according to the present invention, strongly alkaline electrolyzed alkaline water generated by electrolysis operation of an electrolyzed water generator installed independently of the dishwasher is used as tableware. While being introduced into the washing tank in synchronism with the start of the rinsing process in the washing machine, introduction of the electrolytically generated alkaline water into the washing tank is stopped after a predetermined time has elapsed.

  For this reason, in the washing tank into which the strongly alkaline electrogenerated alkaline water generated by the electrolyzed water generating device that is electrolyzed in synchronization with the rinsing process of the dishwasher is introduced, in one step of the rinsing process The rinse water used will be introduced. As a result, the ratio of strongly alkaline electrolytically generated alkaline water to rinsing water is constant, and strong alkaline electrolytically generated alkaline water is diluted to a constant ratio, so that cleaning water having stable characteristics and constant cleaning ability is obtained. Will be prepared.

  Therefore, in the dishwasher according to the present invention, strongly electrolyzed alkaline water generated by the electrolyzed water generating device installed independently of the dishwasher is independent of the electrolyzed water generating device. It can be effectively used as washing water for the dishwasher installed.

  By the way, the washing water prepared in the washing tank in each dishwasher according to the present invention is obtained by diluting strong alkaline electrogenerated alkaline water to a predetermined concentration, and the washing water is in a heated state. In the case where the washing water is left alone or when the washing operation using the washing water is repeated, the pH of the washing water is gradually lowered to cause a phenomenon that the washing ability is gradually lowered. The first dishwasher according to the present invention is intended to deal with the former case, and the second dishwasher according to the present invention is intended to cope with the latter case.

  In the first dishwasher according to the present invention, when the hot water temperature of the washing water in the washing tank is equal to or higher than a set value and a certain period of time has elapsed since the introduction of electrolytically generated alkaline water, A predetermined amount of electrolytically generated alkaline water is additionally introduced. As a result, in the cleaning water in the cleaning tank that has been left at a hot water temperature that is higher than the set temperature and the cleaning performance is decreased due to a decrease in pH, the pH is restored by the predetermined amount of electrolytically generated alkaline water introduced. The cleaning ability is restored.

  The second dishwasher according to the present invention additionally introduces a predetermined amount of electrolytically generated alkaline water into the washing tank when the washing operation exceeds a certain number of times. As a result, in the washing water in the washing tank whose pH is lowered due to repeated washing operation and the washing ability is lowered, the pH is restored by the predetermined amount of electrolytically generated alkaline water introduced, and the washing ability is reduced. Return.

  The present invention is a dishwasher using electrolytically generated alkaline water as washing water. The dishwasher according to the present invention is of a type having a washing process using the electrolytically generated alkaline water contained in the washing tank as washing water, and a rinsing process using the water contained in the rinsing tank as rinsing water. It is a dishwasher, and electrolyzed alkaline water generated by an electrolyzed water generator installed independently from the dishwasher is used as washing water. FIG. 1 schematically shows a dishwasher according to an embodiment of the present invention.

  The dishwasher A uses strongly alkaline electrogenerated alkaline water generated in the cathode side electrolysis chamber of the diaphragm electrolyzer of the electrolyzed water generating apparatus B installed independently from the raw water of the washing water. Therefore, the washing water is prepared by diluting the raw water with the rinsing water introduced into the washing tank in the rinsing step. The electrolyzed water generating device has a known configuration except for the connection relationship with the electrolyzed water generating device B and the operation control relationship with the electrolyzed water generating tank B. The structure itself is also known.

  The dishwasher A includes a washing tank 11 at the bottom of the washing chamber formed in the case body, and a washing nozzle 12 is disposed above the washing tank 11 at a predetermined height, and a rinse nozzle 13 is disposed above the washing nozzle 12. Thus, a storage shelf 14 for storing tableware is installed between the cleaning tank 11 and the cleaning nozzle 12. Moreover, the dishwasher A includes a rinsing tank 15 in a machine room formed in the case body.

  The dishwasher A has a washing process and a rinsing process, and in the operation of the washing process, the washing water in the washing tank 11 is supplied to the washing nozzle 12 through the supply line 21 by driving the washing pump 11a. Then, it is sprayed from the cleaning nozzle 12. The tableware stored in the storage shelf 14 is cleaned by the cleaning water sprayed from the cleaning nozzle 12, and the sprayed cleaning water falls into the cleaning tank 11. The cleaning pump 11a circulates cleaning water through the cleaning nozzle 12 for a predetermined time, and promotes cleaning of the tableware in the storage shelf 14 during this period. After the cleaning of the tableware in the storage shelf 14 is completed, the used cleaning water in the cleaning tank 11 is once drained and then the operation proceeds to the rinsing process. Note that the water supply control of the cleaning water to the cleaning tank 11 is performed by a water supply control method described later.

  In the operation of the rinsing process in the dishwasher A, the rinsing pump 15a is driven to supply the rinsing water (hot water) in the rinsing tank 15 to the rinsing nozzle 13 through the supply line 22 and to be ejected from the rinsing nozzle 13. Washed dishes stored in the storage shelf 14 are rinsed and washed with water. The rinsing water sprayed from the rinsing nozzle 13 drops and is stored in the washing tank 11, but in one-step operation of the rinsing process, a predetermined amount of rinsing water is jetted from the rinsing nozzle 13. When the rinsing water is jetted, the driving of the rinsing pump 15a is stopped and the operation of one process of the rinsing process is terminated. Therefore, when one process of the rinsing process is completed, the cleaning tank 11 is constant. An amount of rinse water will be introduced.

  The rinsing water used in the rinsing process uses rinsing water accommodated in the rinsing tank 15, and the rinsing tank 15 is supplied with water through a water supply line 23 connected to a water pipe in advance. The water supply is stopped when the inside of the rinsing tank 15 becomes full. Rinsing water supply control with respect to the rinsing water tank 15 is performed by opening / closing control of the water supply valve 24 interposed in the middle of the water supply pipe 23.

  Therefore, in the dishwasher A, the electrolytically generated alkaline water generated by the electrolyzed water generator B installed independently of the dishwasher A is used as the cleaning water. The electrolyzed water generator B is a diaphragm electrolysis type electrolyzed water generator known per se. The electrolyzed water generating apparatus B uses dilute saline solution of a predetermined concentration as electrolyzed water, and strongly acidic electrolyzed acidic water is generated in the anode side electrolysis chamber of the diaphragm electrolyzer, and the cathode side electrolysis chamber Then, strong alkaline electrogenerated alkaline water is produced. In this embodiment, so as to generate electrolytically generated acidic water having a very low pH of about 2, so as to generate electrolytically generated alkaline water having a very high pH of about 12 correspondingly. Electrolysis conditions are set.

  In the diaphragm electrolyzer, an extraction pipe 31 dedicated for electrolytically generated acidic water, which is a pipe for extracting each electrolytically generated water generated in each electrolytic chamber, and an extraction pipe 32 dedicated for electrolytically generated alkaline water are provided. I have. The extraction conduit 31 dedicated for the electrolytically generated acidic water is connected to the outlet conduit 33, and the outlet conduit 33 extends above the sink 34 installed in the kitchen. As a result, the electrolytically generated acidic water can be used by being jetted onto the sink 34, and is used for sterilizing and washing various foods.

  On the other hand, the extraction conduit 32 dedicated to electrolytically generated alkaline water in the diaphragm membrane electrolytic cell has a lead-out conduit 35 extending to a location different from the sink 34 and an introduction tube extending above the cleaning tank 11 of the dishwasher A. The flow path switching valve 26 (three-way valve) is interposed at the branch portion of the pipe lines 25 and 35. Thereby, the strongly alkaline electrogenerated 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 26.

  The dishwasher A uses electrolytically generated alkaline water generated in a diaphragm membrane electrolyzer of an electrolyzed water generating device B installed independently of this as cleaning water, and the electrolyzed water generating device B The strongly alkaline electrolytically generated alkaline water generated by the above is introduced into the washing tank 11 through the introduction pipe line 25 by the switching operation of the flow path switching valve 26, and the strong alkaline water introduced in the washing tank 11 is introduced into the washing tank 11. Electrolytically generated alkaline water is diluted to a certain ratio with rinsing water to prepare washing water that is electrolytically generated alkaline water having a predetermined concentration. The washing water is prepared by starting the electrolysis operation of the electrolyzed water generating device B in response to the start of the rinsing process in the dishwasher A, and into the washing tank 11 of the strongly alkaline electrolyzed alkaline water. Is started in response to the start of the rinsing process, and the introduction of the electrolytically generated alkaline water into the washing tank 11 is stopped after a predetermined time has elapsed.

  In this way, if the wash water is prepared in the wash tank 11, the strongly alkaline electrolyzed alkaline water produced by the electrolyzed water producing device B that is electrolyzed in synchronization with the rinsing process of the dishwasher A is obtained. Rinsing water used in one step of the rinsing step can be introduced into the cleaning tank 11 to be introduced. As a result, the ratio of strong alkaline electrolytically generated alkaline water to rinsing water is constant, and strong alkaline electrolytically generated alkaline water is diluted to a constant ratio. Will be prepared.

  In this case, when the inside of the washing tank 11 does not become full, the above-described strong alkaline electrogenerated alkaline water and rinse water are repeatedly introduced into the washing tank 11 as appropriate, and the inside of the washing tank 11 is filled with the washing water. can do. Thereby, in the said dishwasher A, the strongly alkaline electrolysis production | generation alkaline water produced | generated by the electrolyzed water production | generation apparatus B installed independently of this is installed independently of this It can be effectively used as washing water for the dishwasher A.

  In the preparation of the washing water, it is preferable that the supply of the rinsing water into the rinsing tank 15 is stopped while the electrolytically generated alkaline water is introduced into the washing tank 11. This prevents the next operation of the rinsing process from entering the next operation while a predetermined amount of strongly alkaline electrolyzed alkaline water is introduced into the washing tank 11 after the operation of the rinsing process. By repeating the above, the washing tank can be filled with washing water having a constant ratio of strongly alkaline electrogenerated alkaline water to rinsing water. Moreover, if the water level of the rinsing water in the rinsing tank 15 is low during the operation of the washing process in the dishwasher A, there is a possibility that the operation of the rinsing process may not be performed after the washing process is completed. For this reason, the water supply to the rinse tank 15 can be enabled only during the operation of the cleaning process.

  By the way, in the tableware washing machine, depending on the washing operation, the washing operation may be stopped with the washing water stored in the washing tank 11, and the washing operation may be resumed after a while. In some cases, the operation of the rinsing process is performed after repeating the above. In these cases, in the former cleaning operation, the cleaning water in the cleaning tank is left in a heated hot water state, and the pH of the cleaning water gradually decreases, resulting in a phenomenon in which the cleaning performance gradually decreases. Will do. Further, in the latter cleaning operation, by repeatedly using the cleaning water, a phenomenon occurs in which the pH of the cleaning water gradually decreases and the cleaning performance gradually decreases.

  The inventors of the present invention have assumed that the cleaning operation is stopped in a state where the cleaning water is accommodated in the cleaning tank 11, and the cleaning water in the cleaning tank 11 is heated assuming that the cleaning operation is resumed after a while. An experiment was conducted to examine the time-dependent behavior of the pH of the cleaning water in the cleaning tank 11 when left in a hot water state, and the results shown in Table 1 were obtained. In this experiment, the wash water whose pH was adjusted to 11.30 was left in a state maintained at 70 ° C., and the pH of the wash water was measured over time. The pH of the wash water gradually increased according to the standing time. It was confirmed that it decreased. In order to cope with this behavior, strong alkaline electrogenerated alkaline water (pH 11.8) was added to the washing water in an amount of 3% by weight (ratio to washing water) per hour. Confirmed to maintain.

  Therefore, in the dishwasher A, as a first means to deal with these problems, a certain time has elapsed since the temperature of the cleaning water in the cleaning tank 11 is equal to or higher than the set value and the electrolytically generated alkaline water is introduced. In this case, a means for additionally introducing a predetermined amount of electrolytically generated alkaline water into the cleaning tank 11 is adopted. As a result, in the washing water in the washing tank 11 that has been left at a hot water temperature that is higher than the set temperature and the washing ability is lowered due to the lowered pH, the pH is restored by the predetermined amount of electrolytically generated alkaline water introduced. The cleaning ability will be restored.

  In addition, as a second means to deal with each of the above-mentioned problems, a means for additionally introducing a predetermined amount of electrolytically generated alkaline water into the cleaning tank 11 is adopted when the cleaning operation exceeds a certain number of times. . Thereby, in the washing water in the washing tank 11 whose pH is lowered due to repeated washing operation and the washing ability is lowered, the pH is restored by the predetermined amount of electrolytically generated alkaline water introduced, and the washing ability. Will return.

  The dishwasher A executes an operation control program based on a flowchart shown in FIG. 2 based on a cleaning operation command. In step 101, the control device determines whether or not the level of the rinsing water in the rinsing tank 15 is sufficient. If not, the control device opens the water supply valve 24 to supply water into the rinsing tank 15 (step 102). ). When it is determined that the water level of the rinsing water in the rinsing tank 15 is sufficient, the control device determines whether or not the level of the rinsing water in the cleaning tank 11 is sufficient in step 103, and If not, the rinse pump 15a is driven (step 104), and the control program is returned 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 11a is driven to start the cleaning process (step 106), and the cleaning process has been operated for a predetermined time. At the time, the operation is stopped and the washed water in the washing tank 11 is drained, and then the rinsing pump 15a is driven to start the rinsing process (step 107). The control device returns the control program to step 101 after the stop of the rinsing process.

  On the other hand, in the electrolyzed water generating apparatus B, the electrolysis operation is started in response to the start of the operation of the rinsing process in the washing operation of the dishwasher A, and the control device is a flowchart showing the operation control program of the electrolysis operation in FIG. Run based on. In step 201, the control device determines whether or not a certain time has elapsed since the introduction of the electrolyzed alkaline water when the temperature of the cleaning water in the cleaning tank 11 is equal to or higher than the set temperature, and satisfies the condition for the cleaning water to be applied. If yes (YES), the operation control program for the electrolysis operation is shown in FIG. 4 and proceeds to step 210 of the flowchart. If the condition for applying the washing water is not satisfied (NO), the operation control program is shown in FIG. Proceed to step 202 in the flowchart shown. The control device detects the drive of the rinsing pump 15a (step 202), turns on the start switch of the electrolysis operation in the electrolyzed water generating device B, and switches the flow path switching valve 26 to perform the electrolyzed water generating device B. The electrolysis operation is started (step 203).

  Next, the control device closes the water supply valve 24 to stop the water supply into the rinsing tank 15 (step 204), and continues the electrolysis operation for the first set time (step 205). 11 determines whether or not the temperature of the cleaning water in the water 11 is equal to or higher than the set temperature and the number of times of cleaning is equal to or higher than a certain value. When the condition for the washing water is satisfied (YES), the operation control program of the electrolysis operation is advanced to step 207, the electrolysis operation is extended by the second set time, and then the electrolysis operation is stopped (step) 208), the water supply valve 24 is opened and the water supply into the rinsing tank 15 is resumed (step 209). In addition, when the condition for applying the washing water is not satisfied (NO), the control device advances the operation control program of the electrolysis operation to Step 208 and stops the electrolysis operation.

  In step 201, the control device determines whether or not the temperature of the cleaning water in the cleaning tank 11 is equal to or higher than the set temperature and a certain time has elapsed after the introduction of the electrolyzed alkaline water, and the condition where the cleaning water is applied. If YES is satisfied (YES), the operation control program for the electrolysis operation is advanced to step 210 of the flowchart shown in FIG. In step 210, the control device continues the electrolysis operation for a third set time (step 211), then stops the electrolysis operation (step 212), and opens the water supply valve 24 to supply water into the rinse tank 15. Is started (step 213).

  The first set time, which is the electrolysis operation time, is a time during which electrolytically generated alkaline water corresponding to the amount of rinse water introduced into the cleaning tank 11 is introduced. In this embodiment, the amount of rinse water is In the case of 4L, it is set to 2 minutes (flow rate 1L / min, pH 11.8). The second set time, which is the electrolysis operation time, is set corresponding to the time during which the wash water is left. In this embodiment, the hot water temperature of the wash water is 70 ° C. and the electrolyzed alkaline water is generated. Is set to 1 minute (cleaning tank 40L). The third set time for the electrolytic operation is set corresponding to the number of times of cleaning with the same cleaning water. In this embodiment, every time the number of times of cleaning increases by one, 20 seconds are added and a maximum of 2 minutes is set. Is set to add.

  Thus, in the dishwasher A according to the present invention, strongly alkaline electrolyzed alkaline water generated by the electrolysis operation of the electrolyzed water generator B installed independently of the dishwasher A, While being introduced into the washing tank 11 in synchronization with the start of the rinsing process in the dishwasher A, the introduction of the electrolytically generated alkaline water into the washing tank 11 is stopped after a predetermined time.
