DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a cooking water generator according to the present invention will be described below with reference to the drawings. FIG. 1 is a main part configuration diagram showing a first embodiment of a cooking water generator according to the present invention. In FIG. 1, the cooking water generator 1 is an activated carbon for removing chlorine, trihalomethane and the like in tap water. The tap water flows into the activated carbon 2 by the operation of the three-way valve 20 when the cooking water is obtained. At that time, harmful components such as chlorine and trihalomethane are removed.

Next, the three-way valve 21 is controlled so that water flows into the filtration membrane 3. At this time, it is possible to collect turbid components and various bacteria contained in tap water. Next, when the user selects mineral addition and reduction, the purified water that has passed through the three-way valve 22 is branched, and a part goes to the three-way valve 23 and the other goes to the water stop valve 26. When the user selects mineral addition, the water stop valve 26 is opened, and purified water flows into the three-way valve 24. After that, the purified water flows into the mineral addition chamber 4 under the control of the three-way valve 24.

The purified water that has entered the mineral addition chamber 4 becomes high mineral water as the mineral elutes from the additive. Mineral water passes through check valve 18. After that, the hardness of the mineral water is detected by the hardness detecting means 10, the difference in hardness between the mineral water and the purified water is calculated by the control device 8, and the amount of mineral having the optimum hardness for cooking is adjusted by the flow control valve 9.

The mineral water adjusted to the optimum mineral amount flows into the electrolytic cell 6. The electrolytic cell 6 includes a separator 12
And an electrode 11 are provided, and mineral water can be separated into anode water and cathode water. During the electrolysis, a DC current is applied from the power supply 7. At that time, the input voltage and the three-way valve 25 are controlled so that the cathode water can be taken out of the water inlet mainly for cooking. Further, when the electrolysis is not performed, the drainage side is shut off by the water stop valve 28, so that the mineral water can be obtained without waste. FIG. 2 shows a flow chart at the time of intake of mineral adjustment water. With such a structure, cooking water containing minerals optimal for cooking can be generated.

A second embodiment of the cooking water generator of the present invention is shown. A description will be given of a mechanism for preventing clogging of the filtration membrane 3 and propagation of various germs in the cooking water generator of the present invention. The present invention has a water passage that allows water to flow through the filtration membrane 3 from the opposite side to the water. Filtration membrane 3
As a method of back washing, there are a back washing route using tap water and a method using anodic water that can be taken from the electrolytic cell 6, and both are arranged so as to be compatible.

FIG. 3 is a flowchart showing the case of back washing with tap water. In FIG. 3, tap water flowing from an intake port is supplied to a three-way valve 23 by controlling the three-way valve 20. At this time, tap water is not supplied to the activated carbon 2.
The tap water flowing into the three-way valve 23 flows into the three-way valve 22 under the control of the three-way valve 23. Tap water flowing into the three-way valve 22 is introduced into the filtration membrane 3. The tap water that has flowed into the filtration membrane 3 contains the turbid components and some of the germs that have been stored in the filtration membrane 3, is sent to the drainage side under the control of the three-way valve 21, and is discharged outside the machine.

Next, the flow at the time of back washing using the anodic water generated by the electrolytic cell 6 will be described with reference to FIG. In FIG. 4, tap water introduced into the three-way valve 23 flows into the electrolytic cell 6 in the same manner as in the case of the above-mentioned tap water. Tap water flowing into the electrolytic cell 6 is separated into anode water and cathode water by applying a voltage from the power supply 7 to the counter electrode 11. The anode water and the cathode water are configured to be able to take water while being separated by the action of the separation membrane 12.

At this time, it is desirable that the polarity of the counter electrode is reversed. This is for the purpose of removing scale that tends to accumulate on the cathode side when flowing water. The anode water taken in by the electrolysis flows into the three-way valve 22 under the control of the three-way valve 25. The anode water that has flowed into the three-way valve 22 flows into the filtration membrane 3 in the same manner as in the case of the tap water, and is discharged out of the apparatus at the same time as the dirt components and various germs. At this time, a part thereof stays in the filtration membrane, and it is possible to suppress the growth of various bacteria collected in the filtration membrane 3 by the bacteriostatic effect of the anode water.

Further, the present invention has a mineral reduction mechanism (means). The mineral reduction mechanism mainly uses an ion exchange resin. The hardness components calcium and magnesium contained in tap water are removed by the ion exchange resin. At this time, in the case of a sodium-substituted ion exchange resin, maintenance of the ion exchange resin is required because sodium ions are released instead of captured ions.

The cooking water generator of the present invention has a salt adding means 14 as a maintenance means when a mechanism for reducing mineral content is used. At the time of regeneration of the ion exchange resin, the saline is flowed into the mineral reduction mechanism 5 by the operation of the three-way valve 24 by the operation of the regeneration pump 16 to perform the regeneration.

At this time, an aqueous solution having a chlorine ion concentration higher than that of tap water flows into the electrolytic cell. At this time, when an input from the power source 7 is applied between the electrodes 11, sterilized water having a very high sterilizing effect can be obtained. When this sterilizing water is discharged from the water inlet, it is possible to provide sterilizing water capable of effectively sterilizing things such as hands and vegetables. In addition, when this sterilizing water is caused to flow into the filtration membrane 3 by the operation of the three-way valve 25, it is possible to effectively sterilize various bacteria collected in the filtration membrane 3.

The use of a semi-permanent remover eliminates the need for maintenance in the form of replacement, and furthermore, the invention according to claim 6 allows the optimum mineral amount to be accurately varied on the decreasing side. It is possible to
