The dishwasher 1 of the present invention is provided with an electrolysis unit 30 for producing electrolyzed water used as a cleaning liquid. As a result, it is possible to obtain the cleaning effect of the electrolytic water and to use, for example, the detergent for cleaning the dishes. In particular, in this embodiment, the electrolysis unit 30 is provided as a part of the water supply mechanism 8, and the electrolysis unit 30 is made to flow water from an external water supply facility by the water supply mechanism 8. Then, in the dishwasher 1, the electrolyzed water generated by the electrolysis unit 30 is supplied together with the cleaning liquid to the cleaning tank 6 as a part thereof, and the dishes are cleaned using the cleaning liquid in which the electrolytic water is diluted.

By thus diluting, the degree of electrolysis of electrolyzed water, that is, the so-called concentration, can be easily obtained to a desired degree. For example, since it is possible to enhance the cleaning effect with electrolytic water having a concentration suitable for cleaning dishes, it is preferable for a dishwasher that tends to target severe dirt. Further, since the electrolytic water is supplied to the cleaning tank 6 after it is diluted, for example, when the concentrated electrolytic water is used, it is possible to reduce the portion that requires high corrosion resistance corresponding to the concentrated electrolytic water.

In order to obtain such an action, it is conceivable to supply water from the cleaning tank to the electrolysis unit, or to carry out electrolysis while flowing water into the electrolysis unit. In the present embodiment, the following is performed. ing. Since the water supply mechanism 8 is connected to the electrolysis unit 30 and only clean water is put therein, there is no risk that dirt adhering to the dishes adheres to the electrodes 32. The electrolysis unit 30 is separated from the cleaning tank 6 as a separate room and has an electrolytic bath 31 as a water storage container of a predetermined internal volume capable of storing water therein, and a plurality of electrodes 32 arranged in the electrolytic bath 31. Have and. Electrolysis unit 3
0 is designed so that the electrolytic cell 31 and the plurality of electrodes 32 can be handled integrally. Each electrode 32 is made of a metal plate, particularly an electrode plate in which titanium is coated with platinum. This electrode plate is a plate material made of titanium or a titanium alloy having a platinum coating film formed on the entire surface thereof, and a known electrode plate can be used. Since this electrode plate has high corrosion resistance,
High durability can be secured even when thick electrolyzed water is obtained.

As described above, in the electrolysis unit 30, since the cleaning liquid can be efficiently electrolyzed in the electrolytic bath 31, it is preferable to obtain concentrated electrolyzed water. Therefore, even if diluted, the electrolyzed water can be thickened. Also, it can be obtained by diluting concentrated electrolyzed water to increase the amount of the cleaning liquid. In other words, the electrolytic cell 31 for generating the concentrated electrolyzed water can be downsized to a smaller amount than the amount of water used in the cleaning tank 6.

In the present embodiment, as shown in FIG. 3, the electrolysis unit 30 is covered with the cover 40 of the cabinet 5 and accommodated in the cabinet 5. The electrolysis unit 30 is arranged below the tableware basket 7 and on the side of the cleaning tank 6, for example, on the left side, and the bottom portion 13 of the cleaning tank 6 is disposed.
The side wall 42 and the cover 4 along the side wall 42 of the
It is placed in an empty space defined between 0 and 0 so that it does not interfere with the tableware storage space. The electrolysis unit 30 may be arranged on the right side or the rear side of the cleaning tank 6.

The water supply mechanism 8 is, as shown in FIG. 2, a first water supply passage 44 that can be opened and closed to supply water to the cleaning tank 6.
And a second water supply passage 45 as a water supply path that can be opened and closed to supply water to the electrolysis unit 30, and the electrolysis unit 30
And a communication passage 46 that connects the cleaning tank 6 and the cleaning tank 6. The first water supply passage 44 has a pipe 47 and an electromagnetic valve 48 capable of opening and closing the pipe 47. A water supply port 49 that can be connected to an external water supply facility is provided at one end of the first water supply passage 44. The other end of the first water supply passage 44 is connected to a hole formed in the side wall of the rear portion of the cleaning tank 6 so that water can pass therethrough.

The second water supply passage 45 has a pipe 50 and an electromagnetic valve 51 capable of opening and closing the pipe 50. Second water supply channel 45
Has one end connected to the vicinity of one end of the first water supply passage 44,
The water supply port 49 can also be used to connect to an external water supply facility. Further, the other end of the second water supply passage 45 is connected to the inlet 33 of the electrolysis tank 31 of the electrolysis unit 30 so that water can pass therethrough. Further, the second water supply passage 45 is provided with an addition unit 52 for adding a chemical agent such as an electrolysis accelerator to water supplied to the electrolysis unit 30 through the second water supply passage 45. The drug is
For example, it is formed into a solid tablet having a predetermined shape, can be automatically charged, and can be dissolved in water.

Since the addition unit 52 is on the upstream side of the electrolysis unit 30, the flow of the second water supply passage 45
The chemicals can be evenly supplied into the electrolysis unit 30 while being mixed with water. The position at which the addition unit 52 inputs the drug is not particularly limited, and for example, the addition unit 52 may be provided in the electrolytic bath 31 of the electrolysis unit 30 and the drug may be placed in the electrolytic bath 31. The addition unit 52 is electrically driven by a storage container 55 capable of storing a large number of tablets corresponding to a plurality of washings and a predetermined amount of tablets in the storage container 55, for example, a motor for taking out one tablet in order. And a take-out mechanism 56. When the motor is driven, a predetermined amount of electrolysis accelerator is introduced by the take-out mechanism 56 into the second water supply passage 45 through the introduction port formed in the second water supply passage 45. The take-out mechanism 56 can use a known structure. As will be described later, the addition unit 52 is configured so that the medicine can be injected at a predetermined timing by the control of the control unit 60, and by the control of the control unit 60 serving as a switching unit, when water is passed through the second water supply passage 45. Whether to operate or not can be switched.

By the way, it is possible to obtain electrolyzed water by directly supplying electricity to tap water by utilizing impurities that are usually mixed in tap water, but for example, electrolysis efficiency may be lowered. Therefore, in order to accelerate the electrolysis of tap water, an addition unit 52 is provided, and the above-mentioned chemicals contain at least an electrolysis accelerator. The electrolysis accelerator contains a chloride compound and a compound containing an alkali metal. Examples of the chloride compound include sodium chloride (sodium chloride) and calcium chloride. Examples of the compound containing an alkali metal include sodium carbonate and sodium hydrogen carbonate. As the electrolysis promoter, a predetermined amount of a chloride compound and a predetermined amount of a compound containing an alkali metal are both contained in the tablet.

The electrolysis promoter may be any of the above compounds,
Since electricity can be easily applied to water in a state of being dissolved in water, electrolysis efficiency can be increased as compared with the case where tap water is electrolyzed as it is. For example, concentrated electrolyzed water can be easily obtained, and hypochlorous acid and hypochlorite ions are easily generated, so that the concentration of hypochlorous acid and hypochlorite ions in electrolyzed water can be increased. As a result, the effect of bleaching tableware and the effect of sterilizing tableware can be enhanced. At the same time, since the degree of alkalinity of the electrolyzed water can be increased, the effect of dissolving and decomposing proteins can be increased.

The electrolysis accelerator can prevent the cleaning effect of electrolyzed water from varying between regions. That is, usually, the conductivity of tap water differs depending on the region, and the easiness of current flow differs depending on the conductivity of the water, and as a result, the degree of electrolysis of electrolyzed water differs when electrolyzing under the same conditions. However, by adding the above-mentioned electrolysis accelerator, the conductivity of the above-mentioned aqueous solution becomes significantly higher than that of tap water. Therefore, the conductivity of the water to be electrolyzed can be kept substantially constant at a value determined by the electrolysis promoter without being affected by the regional difference in the conductivity of tap water, and the degree of electrolysis of the generated electrolysis water, As a result, the cleaning effect can be almost constant. Further, when comparing the same amount of electric current that is passed to obtain electrolyzed water of a predetermined concentration, when the electrolysis promoter is added, the gap between the electrodes 32 can be widened, so that scale adhesion can be suppressed. Due to impurities in the water, this scale is
2 is a solid layer deposited on the surface of the electrode 32. If such a scale adheres to the surface of the electrode 32, the electrolysis efficiency decreases, but in the present embodiment, the adhesion is suppressed as described above.

In particular, when the electrolysis accelerator contains a chloride compound, in addition to chlorine originally contained in tap water, the chloride compound contained in the electrolysis accelerator dissolves in water to form chlorine in water. The concentration increases. Furthermore, the degree of electrolysis of electrolyzed water is increased by the action of the electrolysis accelerator. As a result, hypochlorous acid and hypochlorite ions are more easily generated in the electrolyzed water,
The concentration of hypochlorous acid and hypochlorite ion in the electrolyzed water is further increased, and the effects of bleaching tableware and sterilization are further enhanced. For example, when sodium chloride is used as the electrolysis accelerator, the predetermined amount of the electrolysis accelerator is dissolved in water to obtain an aqueous solution having a predetermined concentration, for example, 1% or less. Is preferred. This is because if the concentration of the aqueous solution exceeds 1%, an excessive amount of chlorine may be generated when the aqueous solution is electrolyzed.

When the electrolysis accelerator contains a compound containing an alkali metal, the compound containing an alkali metal is dissolved in the electrolyzed water to further enhance the alkalinity of the electrolyzed water, and thus the washing solution, to thereby enhance the protein content. The effect of dissolving can be further enhanced. For example, when sodium carbonate is used as the electrolysis accelerator, the predetermined amount is set to be an aqueous solution containing sodium carbonate in the electrolytic bath 31 at a concentration of 0.3% or more. An aqueous solution of this concentration is electrolyzed, the electrolyzed water obtained thereby is diluted, and this diluted electrolyzed water is used as a cleaning liquid. The cleaning liquid is made to have an alkalinity of pH 10.5 while being diluted and then stored in the cleaning tank 6. With this washing liquid, the action of dissolving the protein adhering to the dishes can be obtained to a sufficient extent for washing the protein.

Further, the drug may contain an enzyme such as amylase. Enzymes function as catalysts for chemical reactions that decompose dirt. In particular, amylase facilitates the decomposition of starch and the like. Since these chemicals are significantly cheaper than the detergent, the cost for cleaning can be reduced as compared with the case where the detergent is used for cleaning. Further, with the above-mentioned chemicals, even if the chemicals are discharged to the outside together with the cleaning liquid after cleaning, there is no fear of polluting the environment.

As the shape of the drug, for example, a projection may be formed on the surface of the tablet to increase the surface area and make it easier to dissolve in water. In addition, as a drug, a plurality of three components of an electrolysis accelerator composed of a chloride compound, an electrolysis accelerator composed of a compound containing an alkali metal, and an enzyme,
For example, all components may be contained in one tablet. When all the components are contained in one tablet, only one type of tablet needs to be handled, and therefore it is easy to put them in the electrolytic cell 31 or the like, and for example, the structure of the addition unit 52 can be simplified. Further, each of the above-mentioned three components may be formed into a separate tablet, and in this case, the time and effort for mixing the three components during the production of the tablet can be omitted, and the tablet can be easily produced.

The electrolysis promoter is not limited to the case where both the chloride compound and the compound containing an alkali metal are contained, and for example, only one of the compounds may be contained. Further, the structure of the addition unit 52 is not limited to that described above. For example, the chemical may be manually added every cleaning operation. For example, a container may be provided in the door 4 for containing the drug, and the drug may be dropped from the container into the electrolytic bath 31 or the second water supply passage 45 at a predetermined timing. In this way, the addition unit 52 is attached to the door 4.
It is preferable to provide the item because it is easy for the user to handle.

A configuration in which the addition unit 52 is omitted may be considered. In this case, the structure can be simplified. In addition, the second water supply passage 45 and the communication passage 46 are connected to the first water supply passage 44.
It is also possible to make it function as. Hereinafter, the case where the addition unit 52 is provided and the drug contains a chloride compound, a compound containing an alkali metal, and an enzyme will be mainly described.
The communication passage 46 is made of a pipe, and connects the outlet 34 of the electrolytic cell 31 of the electrolysis unit 30 and the opening 43 formed in the side wall 42 of the water reservoir 17 below the cleaning tank 6 as shown in FIG. . The communication passage 46 is configured to flow water from the electrolysis unit 30 to the cleaning tank 6.

The communication passage 46 has a raised middle portion 54, and this portion 54 is arranged at a position higher than the outlet 34 of the electrolytic cell 31 of the electrolysis unit 30 and higher than the opening 43. As a result, it is possible to more reliably prevent the entry of the residual food into the electrolysis unit 30. The outlet of the communication passage 46 may be connected to a portion which is the bottom portion 13 of the cleaning tank 6 and is separated from the filter 18 and in which residual food is hard to collect, but in the present embodiment, the outlet is connected as described below, and the cleaning pump 9 is connected. I'm trying to be sucked in quickly.

The opening 43 to the water reservoir 17, which is the outlet of the communication passage 46, is a portion where the cleaning liquid after being filtered by the filter 18 is stored, and the side wall 4 below the filter 18.
It is located in part 2. As a result, it is possible to prevent the leftover food from reaching the outlet of the communication passage 46, and thus it is possible to prevent an unnecessary reaction between the leftover food and the like and the electrolyzed water. Therefore,
It is possible to prevent the cleaning effect of electrolytic water from being lowered before being used for cleaning due to such a reaction, and as a result, it is possible to effectively clean the dirt adhering to the dishes while maintaining a high cleaning effect of electrolytic water. be able to.

When the cleaning liquid sprayed on the dishes falls and collects on the bottom portion 13 of the cleaning tank 6, the filter 18 filters the cleaning liquid to pass it through and removes the residual foods that have fallen together with the cleaning liquid from the cleaning liquid. It is for doing. The filter 18 is formed in a mesh shape and has holes through which the cleaning liquid passes. This hole is formed by, for example, a rectangular mesh having a side length of about 2 mm. With the water supply mechanism 8, water can be stored in the cleaning tank 6 through the first water supply passage 44, and at the same time, water can be stored in the electrolysis unit 30 through the second water supply passage 45. The electrolysis unit 30 electrolyzes water stored therein to generate electrolyzed water. Then, by opening the second water supply passage 45 and supplying water to the electrolysis unit 30, it is possible to dilute the electrolyzed water in the electrolysis unit 30 together with the water through the communication passage 46 to the cleaning tank 6.

Thus, the separate first and second water supply passages 44 and 45 of the water supply mechanism 8 can increase the degree of freedom of water supply and shorten the time for cleaning. For example, water can be supplied to the cleaning tank 6 in a state where water is not collected and stored in the electrolysis unit 30 during preliminary rinsing described later. Further, in order to supply the electrolyzed water after diluting it, the electrolyzer 31
Although it may be considered to flow out after dilution in the inside, in the present embodiment, it is achieved in a short time by utilizing the pushing of water into the electrolytic cell 31.

Further, since the pushing of the water flowing into the electrolytic bath 31 is used for supplying the electrolyzed water, the structure of the communication passage 46 can be simplified. For example, it is not necessary to provide a valve or the like in the communication passage 46.
Further, it can be effectively used for cleaning without leaving the thick electrolyzed water in the electrolytic bath 31. In addition, the second water supply passage 45 and the communication passage 4
6, when the electrolyzed water is supplied to the cleaning tank 6, the electrolyzed water can be surely diluted while being extruded with clean water, and the inside of the electrolysis unit 30 can be rinsed with water for extruding the electrolyzed water. . As a result, for example,
Since the adhesion of the scale can be suppressed, it is possible to prevent a short circuit between the electrodes 32 due to the scale and a decrease in electrolysis efficiency. Further, it is possible to prevent the electrolyzed water from remaining inside the electrolysis unit 30, so that the durability can be improved.

As shown in FIGS. 3 and 4, the electrolytic bath 31 is formed of a synthetic resin material separately from the cleaning tank 6, and the amount of water that can be used as a cleaning liquid by diluting the electrolytic water generated inside. It has an internal volume that can store
The cleaning tank 6 is designed to store an amount of water that is approximately one third or less of the amount of water that is stored during cleaning. With such an internal volume, the electrolytic unit 30 can be housed in the cabinet 5 without enlarging the outer shape of the dishwasher 1. For example, in the present embodiment, the amount of water accumulated in the electrolytic cell 31 is set to about 1/10 of the amount of water accumulated in the cleaning tank 6 during cleaning.

The electrolytic cell 31 is detachably fixed to the base 41 of the cabinet 5 as a structural member by screwing. The cleaning tank 6 may be used as the structural member. The electrolytic cell 31 is formed in a thin box shape that is thinned in the left-right direction. The electrolytic cell 31 is composed of a pair of split bodies 35 and 36 that can be split up and down. A space between the divided bodies is sealed by a sealing member 37 such as an O-ring.

The upper portion of the electrolytic cell 31 has a protruding portion 38 that protrudes higher. The inside of the protruding portion 38 is an air reservoir without the water stored in the electrolytic cell 31 entering. As a result, the gas generated during electrolysis can be stored in the electrolytic bath 31 without being discharged to the outside, and the gas stored therein can be redissolved in the electrolyzed water to improve the electrolysis efficiency. The projecting portion 38 is arranged biased to the front part of the electrolytic cell 31. The electrodes 32 are arranged so as to be biased toward the rear side, which is the side far from the protrusion 38. The upper end of the electrode 32 is made lower than the water level H accumulated in the cleaning tank 6 during cleaning, and even if the water in the electrolytic cell 31 flows into the cleaning tank 6 through the communication passage 46 due to the siphon effect.
The electrode 32 is designed to be surely submerged in water. Also,
The rear surface portion of the electrolytic cell 31 is close to and adjacent to the electrode 32, and a pair of tubular extending portions extends rearward. In the extension part,
The pipe of the communication passage 46 and the pipe 50 of the second water supply passage 45 are connected. One extension on the lower side defines an inlet 33 for introducing water into the inside, and the other extension on the upper side defines an outlet 34 for discharging water from the inside.

The inlet 33 of the electrolytic cell 31 is disposed near the bottom of the electrolytic cell 31, for example, at a position corresponding to a substantially middle portion of the electrode 32 in the height direction. The outlet 34 is arranged at the upper end of the side of the electrolytic cell 31 and above the upper end of the electrode 32. Inlet 33 and outlet 3 of the electrolytic cell 31
4 are spaced apart from each other in the vertical direction, and are arranged so that water flows in the horizontal direction in opposite directions and in parallel. As a result, water enters from the inlet 33, flows in a wide area inside in a folded manner, and the electrolyzed water inside and tap water are uniformly mixed between them, and the electrolyzed water inside is efficiently pushed out, and the outlet 34
Can be flushed through. In addition, stagnation of water inside the electrolytic cell 31 and generation of air pockets near the electrodes 32 can be suppressed, and efficient electrolysis can be performed.

Further, the electrolytic cell 31 serving as the inlet of the communication passage 46
The outlet 34 is located at a position higher than the water level H of the cleaning liquid stored in the cleaning tank 6 during cleaning, and can prevent the cleaning liquid from the cleaning tank 6 from flowing back to the electrolysis unit 30. Therefore, it is possible to prevent the entry of the residual food into the electrolysis unit 30. Each of the electrodes 32 is in the shape of a rectangular thin plate having substantially the same shape, and the electrodes 32 are arranged so as to face each other such that the surfaces of the respective electrodes 32 face the thinning direction of the electrolytic cell 31, for example, the left-right direction. Each electrode 32 stands upright, and the gas generated on the surface of the electrode 32 during electrolysis is generated by the electrode 32.
Since it can be easily separated from the surface of, the deterioration of the electrolysis efficiency due to the adhesion of gas can be suppressed.

The lower ends of the electrodes 32 are held in the electrolytic bath 31 and are separated by a predetermined distance (D3). The electrodes 32 may be held at the left and right ends and the upper end parts. The number of the plurality of electrodes 32 is, for example, three. The plurality of electrodes 32 are a pair of electrodes 3 having opposite polarities.
Have two. For example, in the case of three electrodes 32,
The polarities of the electrodes 32 may be alternately switched so that the two electrodes 32 adjacent to each other have opposite polarities. The number of electrodes 32 may be four or five, and at least a pair of electrodes 32 may be provided.

By the way, normally, when water is stored and electrolyzed,
The scale tends to adhere to the electrode 32. Therefore,
Even if the scale adheres to the electrode 32, the interval between the electrodes 32 is set as follows so that a short circuit between the electrodes 32 via the scale can be prevented for a long period of time. As a result, for example, there is no problem in practical use in standard home use. Distance between electrodes 32 (see D3)
The distance (see D4) between the electrode 32 and the inner wall 39 of the electrolytic cell 31 is preferably, for example, 3 mm or more and 5 mm or less. This is because if the distance is less than 3 mm, the scale is likely to adhere to the electrode 32, the electrolysis efficiency is reduced, and a short circuit due to the adhered scale may occur. Further, if the distance exceeds 5 mm, it is necessary to apply a high voltage in order to maintain high electrolysis efficiency, which makes it difficult to practically construct the device. The distance between the electrode 32 and the electrolytic cell 31 (D4)
May be of the above dimensions, or 0, ie
A gap may not be opened between the electrode 32 and the electrolytic cell 31.

By the electrolysis unit 30 and the washing tank 6 described above, electrolyzed water is produced as follows, and exerts a washing effect. That is, tap water is stored in the electrolytic bath 31. This tap water originally had iron, calcium,
A small amount of inclusions such as magnesium and chlorine are contained, and in addition to this, the above-mentioned electrolysis accelerator is mixed. In this way, tap water is stored in the electrolytic cell 31 and electrolyzed in a state of containing a large amount of inclusions to generate concentrated electrolytic water. The degree of electrolysis is increased by using an electrolysis accelerator, and the alkaline compound is further strengthened by using a compound containing an alkali metal as an electrolysis accelerator. In the electrolyzed water, hypochlorous acid (HC
10) and hypochlorite ions (ClO −) are generated, the degree of electrolysis is increased as described above, and a chlorine compound is further used as an electrolysis accelerator, whereby hypochlorous acid and hypochlorous acid are generated. Chlorate ion concentration is high. In addition, the electrolyzed water contains an enzyme.

Thereafter, the concentrated electrolyzed water as described above is supplied from the electrolyzer 31 to the cleaning tank 6 as a cleaning liquid while being diluted with tap water. As a result, the cleaning liquid has a predetermined degree of electrolysis and alkalinity suitable for cleaning dishes, and the enzyme, hypochlorous acid and hypochlorite ion flow into the cleaning tank 6 together with the electrolyzed water. Dirt adhering to the dishes in the washing tank 6
It is decomposed and dissolved by the effect of alkaline water, the effect of spraying the cleaning solution, the effect of hypochlorous acid and hypochlorite ion, and the effect of enzyme, and is dropped. Also, bleaching tableware due to the effect of hypochlorous acid and hypochlorite ions, for example,
The tea astringent is washed and sterilized. Further, since the cleaning liquid is strongly alkaline, it exhibits a high cleaning ability for proteins. In addition, enzymes make starch easier to break down.

The degree of dilution of the concentrated electrolyzed water can be appropriately set according to the degree of contamination, the presence or absence of chemicals, and the chemicals used. For example, electrolytic water having a relatively high degree of electrolysis can be generated by reducing the degree of dilution. Therefore, even when a compound containing an alkali metal is not used as the electrolysis accelerator, the degree of alkalinity can be increased and the concentration of hypochlorous acid or hypochlorite ion can be increased. As a result, the cleaning ability can be improved.

Further, the dishwasher 1 of the present invention is shown in FIGS.
As shown in FIG. 5, the control unit 60 has a control unit 60 for controlling the above-mentioned units according to a predetermined procedure to execute the cleaning operation, and an operation panel 61 connected to the control unit 60 for operation. The control unit 60 includes, for example, a microcomputer (CPU), RAM, ROM, timer, and the like, and controls the motor 21 and the like to perform cleaning based on a program stored in advance and a signal from a switch of the operation panel 61. .

The control unit 60 controls the rotation of the motor 21 via a drive circuit (not shown) and switches the rotation direction of the motor 21, thereby switching between the operation of the washing pump 9 and the operation of the drainage pump 22. . Further, the motor 21 can be driven in a predetermined manner, for example, intermittently.
In addition, the control unit 60 includes an energizing circuit 63 having a transformer or the like.
It is possible to control the energization to the plurality of electrodes 32 of the electrolysis unit 30 via the. Further, the control unit 60 operates the solenoid valves 48 and 51 to cause the first and second water supply passages 4 to operate.
Open and close 4,45. Although not shown, a water level sensor for detecting the water level in the cleaning tank 6 is connected to the control unit 60, whereby the first and second water supply paths 44, 4 are connected.
The water through 5 can be stored up to a predetermined water level.
In addition, the control unit 60, via a drive circuit (not shown),
It is connected to the heater 24 and the blower 25.

On the operation panel 61, a power key (not shown) for turning on the power, a start key 62 as a cleaning start means for starting cleaning, and a course as selection means for selecting a cleaning course. And a key (not shown). By operating the koskey, it is possible to select either the cleaning course or the electrolytic water course. In the detergent course, a standard washing operation is performed using detergent. In the electrolyzed water course, a cleaning operation is performed by using electrolyzed water as a cleaning liquid without using a detergent.

The control unit 60 executes the following processes based on the program stored in advance. Please refer to the flowchart of FIG. 5 and FIG. When the electrolyzed water course is selected, the control unit 60 executes the pre-washing execution process (step S1) executed by the start key 62 to remove rough dirt adhering to the dishes and the dish rinsing after the pre-washing execution process. The preliminary rinsing process (step S2) and the electrolyzed water production process (step S3) of producing electrolyzed water by the electrolysis unit 30 during the operation of the pre-washing process are performed. After that, the control unit 60 supplies the diluted electrolytic water as the cleaning liquid to the cleaning tank 6 to perform the main washing execution process of performing the main washing of the dishes using the electrolytic water (step S4), and performs the rinsing after the main washing. First to third rinse execution processing (step S
5, 6, 7) and a drying execution process (step S8) for drying the washed dishes.

In the prewashing process, the first water supply passage 44 is opened and water is stored in the washing tank 6 for prewashing. Cleaning pump 9
Is operated for a predetermined time, for example, 10 minutes, and the heater 24
Is washed with water at room temperature without being energized. Then drained. In the preliminary rinsing process, the first water supply passage 44 is opened and water is stored in the cleaning tank 6 for rinsing. The cleaning pump 9 is
The heater 24 is operated for a predetermined time, for example, for 1 minute, and the heater 24 is not energized and is rinsed with water at room temperature. Then drained. The predetermined time here is shorter than the operating time of the cleaning pump 9 in the pre-cleaning execution process.

The combination of the pre-washing execution process and the preliminary rinsing process may be executed a plurality of times. In addition, the operating time of the cleaning pump 9 in the pre-cleaning execution process may be extended or the heater 24 may be energized. In these cases, the cleaning effect can be further enhanced. When the operating time of the cleaning pump 9 is extended, it is desirable that the operating time be such that no bubbles are generated due to dirt. In addition, when the heater 24 is energized, it is preferable that the water temperature does not exceed 45 ° C. because the protein is not solidified and can be easily dropped.

In the prewashing process, water is supplied into the washing tank 6 using the second water supply passage 45, and the chemical agent is added to tap water by the addition unit 52 without operating the electrolysis unit 30 at this time. You may make it wash | clean the dish in the washing tank 6 by obtaining the cleaning liquid containing a chemical | medical agent.
That is, even if it is not electrolyzed water, by mixing the above-mentioned chemicals, the alkalinity of the cleaning liquid is increased to some extent, and proteins can be easily removed during pre-washing, and starch can be easily removed by the enzyme of the chemicals. When the chemical is added in the pre-washing process, after the water supply to the washing tank 6 is completed,
The electrolyzed water generation process is started, and the chemical is added again to obtain electrolyzed water.

In the electrolyzed water producing process, the second water supply passage 45 is opened to store water in the electrolysis unit 30, and electrolyzed water is produced from the water. The electrolyzed water generation process is simultaneously executed in parallel from the start of the pre-washing execution process to the end of the rinsing execution process, and during that time, electrolysis is continuously performed while water is stored in the electrolytic cell 31. As a result, the total stroke time for cleaning (steps S1 to S8) can be shortened.
In the electrolyzed water generation process, first, water is supplied up to a predetermined water level in the electrolyzer 31 of the electrolysis unit 30. For example, the second water supply passage 45 is opened for a predetermined time, and the addition unit 52 is
Causes a prescribed amount of drug to be introduced. In the meantime, a standard flow rate of tap water flows into the electrolytic cell 31 from the second water supply passage 45 to reach the above-mentioned predetermined water level. When the water exceeds the capacity of the electrolytic bath 31, the water flows out into the cleaning tank 6 through the communication passage 46 and is stored therein. Then, the plurality of electrodes 32 are energized. At this time, water does not enter and leave the electrolysis unit 30, the flow of water inside the electrolytic cell 31 is suppressed, and electrolysis efficiency is enhanced. Here, the predetermined water level is a water level at which the plurality of electrodes 32 are submerged and the electrolysis tank 31 is almost filled with water, but at least a part of the plurality of electrodes 32 is submerged to start electrolysis. The water level may be such.

The main-washing execution process is executed after the water used in the pre-washing is drained from the washing tank 6, and the second water supply passage 4
5 is opened to supply water, and the diluted electrolytic water in the electrolysis unit 30 is pushed into the cleaning tank 6 while being diluted, and the diluted electrolytic water is supplied to the cleaning tank 6 as a cleaning liquid to be stored therein for main cleaning. In the main washing, the washing pump 9 is operated for a predetermined time, for example, 17 minutes. Then, the heater 24 is energized to heat the water from room temperature to a predetermined temperature, for example, 60 ° C. While the cleaning pump 9 is operating, the heater 2
According to 4, cleaning is performed with a high temperature cleaning liquid containing electrolyzed water while maintaining the water temperature. Then drained.

In the main washing, washing is performed by the action of spraying the washing liquid, the action of the alkaline component of electrolyzed water, the action of hypochlorous acid and its ions, and the action of a high water temperature, and in particular, the water temperature is gradually raised during washing. By doing so, stains such as proteins and starch can be efficiently decomposed and washed. That is, tea astringent and protein are efficiently washed with electrolyzed water at a relatively low temperature. Hypochlorous acid has a high cleaning effect at a temperature of 30 ° C or lower. Subsequent relatively high temperature electrolyzed water can efficiently clean starch and oil stains.

As described above, since the rough dirt is removed by the prewash and discharged to the outside, in the main wash, the electrolytic water is sprayed only on the dirt remaining on the dishes without being removed by the prewash to remove the electrolytic water. It can be effectively used to enhance the cleaning effect. That is, it is possible to prevent an unnecessary reaction between the dirt removed by the pre-washing and the electrolyzed water, and thus it is possible to prevent the cleaning effect of the electrolyzed water from being lowered due to such a reaction. The main washing is not limited to the case where the above-described washing method is adopted, and the point is that washing is performed by using electrolytic water after drainage of pre-washing that does not use electrolytic water.

The first rinse execution process is performed by the second water supply channel 45.
The rinsing water used for rinsing is supplied to the cleaning tank 6 via the electrolysis unit 30. At this time, since the addition unit 52 is not operated, a chemical such as an electrolysis accelerator is not wasted during rinsing. Then, the cleaning tank 6 is filled with water and rinsed. The cleaning pump 9 is operated for a predetermined time, for example, 1 minute, and the heater 24 is not energized and rinsed with water at room temperature. Then drained.

The second rinse execution process is performed by the first water supply channel 44.
Open to rinse water by storing water in the cleaning tank 6. The cleaning pump 9 is operated for a predetermined time, for example, 1 minute, and the heater 24 is not energized and rinsed with water at room temperature. Then drained. In the third rinsing execution process, the first water supply passage 44 is opened and water is stored in the cleaning tank 6 to perform rinsing. The heater 24 is energized and the water is heated to a predetermined temperature, for example, 70 ° C.
Warm until reaching. Then, the cleaning pump 9 is operated for a predetermined time, for example, 20 minutes, during which the heater 24 is energized to perform rinsing with high-temperature rinsing water while maintaining the water temperature. The high-temperature rinsing water has a bactericidal effect, and even if stubborn oil stains remain, they can be reliably removed. Then drained.

As described above, in the first rinse execution process, the rinse water can be flowed to clean the inside of the electrolysis unit 30, so that the generation of rust due to the electrolysis accelerator can be prevented. Further, since adhesion of scale can be suppressed, it is possible to prevent a short circuit between the electrodes 32 due to the scale and a decrease in electrolysis efficiency.
Further, it is possible to suppress the electrolyzed water from remaining inside the electrolysis unit 30, so that the durability can be improved. In addition, when the electrolysis accelerator is not used, or when it is possible to pass the sufficient amount of water through the electrolysis tank 31 to wash the inside of the electrolysis unit 30 during the main washing, the first rinsing execution process is referred to as the second rinsing process. It is also conceivable to carry out a similar procedure and not supply the rinse water through the electrolysis unit 30.

Also, the electrolysis accelerator adhering to the inside of the cleaning tank 6 can be reliably discharged to the outside by a plurality of rinsing execution processes (first to third rinsing execution processes).
It is possible to prevent the generation of rust in the cleaning tank 6. In the second and third rinsing execution processes, the rinsing water may be supplied to the cleaning tank 6 through the second water supply passage 45, and at least once or more rinsing water is supplied after the electrolytic water generating process. The second water supply passage 45 and the electrolytic cell 31 may be passed through. It is also possible to open the first water supply passage 44 and simultaneously supply water through both water passages when the second water supply passage 45 is allowed to flow.

The rinsing may be performed by using the electrolyzed water by operating the electrolysis unit 30 during rinsing (first and second rinsing execution processes). Thereby, it is possible to sterilize the tableware. In this case, it is preferable to supply rinsing water through the electrolytic bath 31 during the subsequent rinsing. Further, in the detergent course, the electrolytic device 31 may be operated at the time of rinsing. In the drying execution process, the blower device 25 is operated for a predetermined time, for example, 20 minutes, the heater 24 is energized during that time, and the dishes are dried with a warm air flow.

Further, when the detergent course is selected, the control unit 60 omits the electrolyzed water generating process and similarly performs the above-mentioned processes other than the main washing. In the main washing of the detergent course,
Water is supplied to the predetermined water level through the first water supply channel 44 and the dishes are washed with a detergent. As described above, according to the embodiment of the present invention, the dishes can be washed without using the detergent by using the electrolyzed water generated by the electrolysis unit 30. Since clean water can be supplied to the electrolysis unit 30 from an external water supply facility, there is no risk that the residual food in the cleaning tank 6 will enter the electrolysis unit 30. Therefore, for example, it is possible to prevent the leftover food from clogging in the electrolysis unit 30 and the leftover food from adhering to the electrode 32, and it is possible to prevent a decrease in the electrolysis efficiency due to the leftover food.

Incidentally, the electrolysis unit 30 of the above-mentioned embodiment.
In the dishwasher 1 having the water supply mechanism 8 and the water supply mechanism 8, it is also conceivable to execute a control content different from the above-mentioned control content, for example, an electrolytic water generation process before the pre-washing. It is also possible to implement the above-mentioned control contents by composition other than the above-mentioned dishwasher 1. For example, it is conceivable to generate electrolytic water having an appropriate concentration in the large-sized electrolytic tank 31 and use the electrolytic water in the cleaning tank 6 without diluting it. Also in this case, the rough water is removed by pre-washing, and then the main washing is performed with electrolytic water, so that the electrolytic water is effectively used,
The cleaning effect can be enhanced.

In the above description, the case where both the chloride compound and the compound containing an alkali metal are contained as the electrolysis accelerator has been described, but the present invention is not limited to this. That is, when both are included, the above-mentioned cleaning effect can be enhanced, which is preferable. On the other hand, there are cases where it is not necessary to enhance the cleaning effect so much for only light dirt. Correspondingly, when setting a cleaning course for light dirt, as the electrolysis accelerator, use only one of a chloride compound and a compound containing an alkali metal, or any electrolysis accelerator It can be considered not to use it (in this case, tap water is directly electrolyzed). Also, use an electrolysis accelerator consisting only of chloride compounds in combination with an enzyme, use an electrolysis accelerator consisting only of compounds containing an alkali metal in combination with an enzyme, and put in only a drug containing only enzymes. It is also possible to

Further, the present invention may be applied to other types of dishwashers such as a tabletop type and a built-in type to be accommodated in a sink. Further, the planar shape of the dishwasher 1 may be elongated in the front-rear direction, may be elongated in the left-right direction, or may be formed in a substantially square shape. Moreover, you may apply the electrolysis unit 30, the addition unit 52, etc. which were mentioned above to washing machines other than a dishwasher. As this washing machine, a washing machine for washing clothes as an article to be washed can be exemplified. For example, a washing machine includes an electrolysis unit 30 for generating electrolyzed water, and the electrolysis unit 30 electrolyzes using water in which an electrolysis accelerator containing a chloride compound and a compound containing an alkali metal is mixed. The water is generated, and the electrolyzed water generated by the electrolysis unit 30 is supplied as a cleaning liquid to a washing tub as a cleaning tank, and a cleaning liquid containing electrolytic water is stored in the washing tub. Wash the stored clothes. A known washing machine configuration can be used as a configuration for collecting the washing liquid in the washing tub to wash the clothes. The washing liquid and the clothing are stirred in the washing tub, and the water flow, the clothes or the clothes and the washing tub are stirred. Clean by rubbing against. The electrolysis unit may be connected to the washing tub in the same manner as the washing tank 6 of the dishwasher 1 described above, or the washing liquid in the washing tub may be connected to the electrolytic tub of the electrolysis unit so that it can enter and leave. Well, a well-known connection method or mounting structure of the electrolytic unit to the washing tub can be used.

Since the concentration of hypochlorous acid and hypochlorite ion in electrolyzed water can be further increased by the above-mentioned chloride compound of the electrolysis accelerator, the effect of bleaching the object to be cleaned and the sterilization of the object to be cleaned can be obtained. It is possible to further enhance the effect. Furthermore, since the alkali metal-containing compound further strengthens the alkalinity of the electrolyzed water, the effect of dissolving the protein adhering to the object to be cleaned can be further enhanced. Therefore, the cleaning effect of the cleaning machine can be enhanced.

Besides, various modifications can be made within the scope of the claims of the present invention.
