(Embodiment 1)
FIG. 1 is an explanatory view schematically showing the configuration of the first embodiment of the dishwasher according to the present invention. In this dishwasher, tableware 45 placed on a tableware bowl 3 is stored in a washing tub 2 that occupies most of the cabinet 1 (housing). The tableware bowl 3 is accommodated in the washing tub 2 so as to be slidable outside with the door of the cabinet 1 opened.

A pump 7 connected to the shaft of the motor 8 is disposed at the bottom of the cleaning tank 2. The pump 7 uses, for example, a forward / reverse rotating motor 8, and the pump casing is formed with one suction port and two discharge ports. The discharge ports are respectively connected to the cleaning discharge pipe 9 and the drain discharge pipe 10, and a switching valve (not shown) is provided at both discharge openings so that only one of the discharge openings is opened.
When the pump 7 rotates in the forward direction, the water sucked from the suction pipe 6 is pumped to the washing discharge pipe 9 by closing the drain discharge port in the switching valve by the dynamic pressure of the flow in the casing by the rotation of the pump impeller. The When the pump 7 rotates in the reverse direction, the water in the cleaning tank 2 has a structure in which the switching discharge valve closes the cleaning discharge port and is pumped to the drain discharge pipe 10.

As the pump 7 rotates forward, the cleaning water stored in the cleaning tank 2 is filtered by the residue filter 5 and is pumped from the suction pipe 6 through the cleaning discharge pipe 9 to the rotary nozzle 11. The plurality of mouths are sprayed onto the tableware 45 stored above.
Next, when the pump 7 rotates in the reverse direction, the water accumulated in the cleaning tank 2 is discharged from the suction pipe 6 to the outside through the drain discharge pipe 10.
The configuration of the pump 7 is not limited to this, and one motor shaft has a casing of two chambers, and a suction port and a discharge port are formed in each chamber. An impeller may be provided to switch between cleaning and drainage by forward and reverse rotation, and a cleaning pump and motor, a drainage pump and motor may be provided independently.

A heater 4 is disposed at a position where the water is immersed in water in a state where water has accumulated in the cleaning water level near the bottom of the cleaning tank 2. The heater 4 heats cleaning water during cleaning and rinsing, and heats and dry the air in the cleaning tank during drying.
A control circuit 12 for executing and controlling a series of sequences from washing, rinsing, and drying using various sensors is disposed at the bottom of the cabinet 1.

  The connection unit 14 is connected to a water tap through a hose (not shown) and supplies tap water into the system. On the downstream side of the connecting portion 14, the water supply path branches in two directions, one of which directly leads from the tap water supply valve 18 through the tap water supply pipe 20 to the tap water supply port 21 of the cleaning tank 2. . The other communicates from the functionalized water supply valve 19 via the functionalized water supply pipe 22 to the upper part of the water supply functionalization device 24 (functionalization means).

Inside the water supply functionalization device 24, a functionalized cartridge 25 having a large number of openings around it is disposed, and inside this is filled with pellets 26 formed by molding silver-exchanged zeolite in the form of granules as a functionalizing component. Has been. The functionalized cartridge 25 containing the pellet 26 can be easily removed from the cabinet 1 and replaced by opening the lid 28 on the top surface of the cabinet 1 and removing the cap 27 at the top of the water supply functionalizing device 24. I can do it.
A functional water supply pipe 29 is connected to the bottom of the water supply functionalizing device 24 and communicates with the functional water supply port 23 of the cleaning tank 2.

Below, operation | movement of the dishwasher of such a structure is demonstrated.
First, the user sets the tableware 45 in the tableware bowl 3, puts a special detergent into the cleaning tank 2, and closes the door of the cabinet 1.
When the start key is pressed, the control circuit 12 opens the tap water supply valve 18, supplies a certain amount of tap water into the cleaning tank 2, rotates the pump 7 forward, and starts injection from the rotary nozzle 11. . At the same time, the heater 4 is energized, the water is heated to the set temperature, and the washing process is executed by the action of the hot water and the physical force by the jet from the hot water nozzle and the detergent.

When the set time or the set temperature of water reaches about 60 ° C., the control circuit 12 rotates the pump 7 in the reverse direction to drain the water from the drain port 13.
Next, the control circuit 12 repeats several times the water supply by the tap water supply valve 18 and the rinsing process from the water nozzle injection to the drainage without energizing the heater 4 several times.
In the final rinsing step, the control circuit 12 opens the functionalized water supply valve 19 to supply water to the upper part of the water supply functionalizing device 24, and the granular silver exchanged zeolite 26 layer in the functionalized cartridge 25 incorporated therein. , And the water is fed into the cleaning tank 2 through the functionalized water supply pipe 29 at the bottom.

At this time, since silver ions are eluted from the granular silver-exchanged zeolite 26 while the water passes through the functionalized cartridge 25, the washing tank 2 is filled with water containing silver ions, and in this state, the final rinsing step I do.
In the final rinsing step, the control circuit 12 performs nozzle injection from the rotary nozzle 11 while energizing the heater 4 to heat the water, and rinses the dishes 45 with hot water.
The control circuit 12 starts drainage when the set time or the set temperature of water reaches about 70 ° C., and when the drainage is completed, the control circuit 12 blows air with a blower fan (not shown) and executes a drying process for energizing the heater 4 for a certain period of time. .

  Thereby, water containing silver ions evaporates in the inside of the washing tank 2, the residue and residue filter 5, and the hydrophilic portion of the tableware 45, and the silver ions remain and are coated to give an antibacterial action. Furthermore, even if the residue is forgotten and left in the cleaning tank 2 for a long period of time, the generation of bad odor due to decay can be suppressed, and slimming in the cleaning tank 2 can also be suppressed.

  Further, if the number of times of washing is counted, the control circuit 12 can predict the time point at which silver ions are not eluted, and can notify the user of the replacement timing of the functionalized cartridge 25. When the user is notified of the replacement timing of the functionalized cartridge 25, the user can easily remove the functionalized cartridge 25 by opening the lid 28 on the top surface of the cabinet 1 and removing the cap 27 at the top of the water supply functionalizing device 24. It can be removed from the main unit and replaced.

When 8g of powdered silver-exchanged zeolite 26 (trade name Bactekiller) is filled in the functionalized cartridge 25 and normal temperature water is passed at a flow rate of 1.5 liters / min, silver ions are stably eluted at a concentration of 30-80 ppb. This state lasted 600 minutes.
A polyethylene chopping board sample was rinsed and dried using water having a silver ion concentration of 90 ppb, and 35 ng / cm ² of silver ions were adhered to the cutting board surface. The antibacterial activity value of this sample against Escherichia coli was 2 or more, and an antibacterial action could be added to the cutting board. That is, when the functionalized water is used for cleaning, an antibacterial action can be added to the cleaning tank 2 and the tableware 45. Similarly, when 80 g of this powdery silver exchanged zeolite 26 is used, approximately 9,000 liters of water can be functionalized.

  The form of the functional component shown in the first embodiment is not limited to this, and the silver exchanged zeolite may be formed into other shapes such as pellets, granules, honeycombs, foams, etc. The shape may be left as it is. Further, it may be kneaded into the resin. In addition to silver-exchanged zeolite, silver may be supported on a porous ceramic such as calcium phosphate, or a compound containing silver may be used.

(Embodiment 2)
FIG. 2 is an explanatory view schematically showing the configuration of the second embodiment of the dishwasher according to the present invention. In this dishwasher, the water supply path branches in three directions from a connection part 14 for supplying tap water into the cabinet 1 through a hose (not shown) from a tap faucet. Water is supplied directly from the tap water supply port 21 of the cleaning tank 2 through the water supply pipe 20. The other communicates from the first functionalized water supply valve 30 via the first functionalized water supply pipe 32 to the upper part of the first water supply functionalization device 34 (functionalization means).

Inside the first water supply functionalizing device 34, a first functionalized rod 35 having a large number of openings around it is disposed, and this is filled with powdered sodium sesquicarbonate 36 as a functionalizing component. . As a form of sodium sesquicarbonate, other than powder, it may be formed into granules, pellets or honeycombs.
The first functionalized rod 35 containing the functionalized component (36) is easily opened by opening the lid 42 on the top surface of the cabinet 1 and removing the cap 37 at the top of the first water supply functionalizing device 34. Can be removed and filled. A functional water supply pipe 29 is connected to the bottom of the first water supply functionalization device 34 and communicates with the functional water supply port 29 of the cleaning tank 2.

  The other branch in the three directions communicates from the second functionalized water supply valve 31 to the upper portion of the second water supply functionalization device 38 (functionalization means) via the second functionalized water supply pipe 33. Inside the second water supply functionalizing device 38, a second functionalized tub 39 having a large number of openings around it is disposed, and this is filled with granular citric acid 40 as a functionalized component.

  The second functionalized basket 39 containing the pellet 40 is also easily removed from the main body by opening the lid 42 on the top surface of the cabinet 1 and removing the cap 41 at the top of the second water supply functionalizing device 38. Can be filled. The functionalized water supply pipe 29 is also connected to the bottom of the second water supply functionalizing device 38 and communicates with the functionalized water supply port 29 of the cleaning tank 2. Other configurations are the same as the configuration of the dishwasher described in the first embodiment, and thus the same parts are denoted by the same reference numerals and description thereof is omitted.

Below, operation | movement of the dishwasher of such a structure is demonstrated.
The user first sets the tableware 45 in the tableware bowl 3 and closes the door of the cabinet 1.
When the start key is pressed, the control circuit 12 opens the first functional water supply valve 30 to supply water to the upper portion of the first water supply functional device 34, and the granularity in the first functionalized tank 35 incorporated therein. The sesquisodium carbonate 36 is passed through and fed into the washing tank 2 through the functionalized water supply pipe 29 at the bottom.

At this time, since the sodium sesquicarbonate is eluted in the water supply while passing through the first functionalized tank 35, the cleaning tank 2 is filled with water containing sodium sesquicarbonate. Since sesquisodium carbonate is hydrolyzed to exhibit alkalinity, water containing sodium sesquicarbonate is supplied into the washing tank 2 in a certain amount as alkaline water.
In this state, the control circuit 12 rotates the pump 7 in the forward direction and starts injection from the rotary nozzle 11 to the dishes 45. At the same time, the heater 4 is energized to heat the water in the cleaning tank 2 to a set temperature.

At this time, the stains on the tableware 45 are washed by a physical force generated by spraying hot water and hot water nozzles without using a detergent, and the oil stains are emulsified in water by the saponification action of alkaline water. The process is executed.
When the set time or the set temperature of water reaches about 60 ° C., the control circuit 12 rotates the pump 7 in the reverse direction to drain the water from the drain port 13.
Next, the control circuit 12 repeats the water supply by the tap water supply valve 18 and the rinsing process from the water nozzle injection to the drainage without energizing the heater 4 several times.

  In the final rinsing step, the control circuit 12 opens the second functionalized water supply valve 31 to supply water to the upper part of the second water supply functionalizing device 38, and the granular quencher in the built-in second functionalized tank 39. The acid 40 is allowed to pass through, and the water is fed into the cleaning tank 2 through the functionalized water supply pipe 29 at the bottom.

At this time, since the citric acid elutes while the water passes through the second functionalized tub 39, the washing tank 2 is filled with water in which citric acid is dissolved, that is, acidic water having a pH of about 2, and in this state A final rinse step is performed.
In the final rinsing step, the control circuit 12 performs nozzle injection from the rotary nozzle 11 while energizing the heater 4 to heat the water, and rinses the dishes 45 with hot water.
The control circuit 12 starts drainage when the set time or the set temperature of water reaches about 70 ° C., and when the drainage is completed, the control circuit 12 blows air with a blower fan (not shown) and executes a drying process for energizing the heater 4 for a certain period of time. .

At this time, since the calcium carbonate in the tap water is dissolved in the acidic water, it is possible to obtain a good dry state in which the traces of water droplets hardly remain on the tableware 45. Furthermore, sterilization is possible without raising the water temperature by the action of acidic water.
Similarly to the first embodiment, the control circuit 12 can predict the time when the functionalized component disappears by counting the number of times of cleaning, and notifies the user of the timing of filling the functionalized bag with the functionalized component. I can do it. When the user is notified of the filling timing of the functionalized tub, the lid 42 on the top surface of the cabinet 1 is opened, and the cap 37 or 41 at the top of the first water supply functional device 34 or the second water supply functional device 38. By removing the, the functionalized basket 35 or 39 can be easily removed from the main body and filled.

Here, the functional component of the 1st water supply functionalization apparatus 34 may be sodium carbonate or sodium hydrogencarbonate. The functional component of the second water supply functionalization device 38 may be obtained by impregnating porous ceramic with acetic acid zeolite or calcium phosphate in addition to citric acid.
Moreover, you may add the 3rd functionalization tank filled with calcium salt or magnesium salt to this as a 3rd water supply functionalization apparatus.

  In this case, first, protein stains such as eggs that easily coagulate with heat by passing through the third water supply functionalization device and using hard water rich in calcium ions or magnesium ions and washing at a low temperature of 50 ° C. or less. Is effectively washed using the salt-solubility effect. Next, in the same manner as described above, the oil and fat stains and the starch stains are washed by passing water through the first water supply functionalizing device 34 and washing with warm water of about 50 ° C. or higher of alkaline water. As final rinsing, water can be passed through the second water supply functionalizing device 38 to generate acidic water for rinsing, thereby further improving the cleaning performance without a detergent. You may use this 3rd water supply functionalization apparatus independently.

The form of the functional component shown in the second embodiment is not limited to this. If a functional ceramic component impregnated with a porous ceramic is used in the cleaning step, oil and fat stains can be emulsified, and soil re-adhesion can be prevented.
Moreover, if an enzyme such as amylase, which is a starch degrading enzyme, or protease, which is a proteolytic enzyme, is used as a functionalizing component in the washing step, starch dirt or protein dirt can be effectively washed.

In addition, if a bleaching component such as sodium hypochlorite is used as a functionalizing component in the washing step, a bleaching action can be obtained, and a dish bleaching course can be set in which this is used alone in the washing step.
In addition, if a final finishing process using a porous ceramic impregnated with a finishing agent such as glycerin fatty acid ester and sorbitan fatty acid ester as a functionalizing component is used in the final rinsing step, the water droplet traces on tableware are reduced and the drying efficiency is improved. I can plan.
In addition, if a perfume that is easy to volatilize as a functional component is included in cyclodextrin, which is a sustained-release material, and passed through the final rinsing process, it can relieve the bad odor generated by the residue by masking it. It is possible to suppress the volatilization of the volatile fragrance component and maintain the effect for a long time.

  One or more of the above functionalized components can be used as a functional component of the water supply functionalization device, and can be used properly according to the cleaning course. For example, when there is a lot of oil stains, by selecting a dedicated course for oil stains, the water passing time of the water supply functional device using a surfactant as a functional component can be increased, and the amount of surfactant added can be increased. It becomes possible to make more. In addition, when there are many starch stains or protein stains, by selecting the respective dedicated courses, the water passing time of the water supply functional device using the enzymes that digest each of them is lengthened, and the amount of each enzyme added can be increased. As a result, it is possible to carry out cleaning according to the type of dirt, without the need to put in a detergent.
