2. Description of the Related Art Conventionally, dishwashing and sterilizing apparatuses and methods have used a large amount of detergent and soap to wash away various stains such as fats and oils, proteins and starch attached to dishes. Also,
Most of the sterilization uses high temperature such as hot air or hot water.

[0003]

Detergent has a very strong detergency and is the most used detergent for household, workplace, and industry. However, instead of cleaning things, it now pollutes rivers and lakes as well as sea bays and coasts when it becomes drainage.
Soap has a lesser degree of pollution than detergents, but to some extent still remains a source of pollution. In addition, those that use high temperature such as hot water for sterilization use a lot of heating energy, which is a big problem today for energy saving.

Particularly strong detergents for dishwashers are used. Therefore, the wastewater discharged from these facilities and equipment cannot be caught up by the bacterial treatment even in the case of sewage treatment, and the untreated portion is discharged as it is to rivers and the sea, which has an important influence on environmental problems.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A dishwashing and sterilizing apparatus and method according to the present invention will be described below in detail with reference to the accompanying drawings by using an embodiment thereof. FIG. 1 is a schematic block diagram side view of an embodiment of the dishwashing and sterilizing apparatus and method according to the present invention. FIG. 2 is a schematic side view of the alternative embodiment. It should be noted that these figures are drawn by laying them sideways in relation to the space of the drawings in the electronic application, so of course, please stand them vertically.

First, the strong alkaline water tank 1 contains the strong alkaline water AL having a pH of about 11.5, and the strong acidic water tank 2 has a pH of 3%.
Below, especially strong acid water AC of about 2.5 to 2.6 is contained. The strong alkaline water AL and the strong acidic water AC are ideally obtained by electrolyzing while injecting saline into water such as tap water. Next, there is a permeation / prewashing means 3 using this strong alkaline water AL. The permeation / pre-washing means 3 with this strong alkaline water AL is one in which a part of the above strong alkaline water AL is injected, and the tableware D after eating is dipped into it for about 10 to 15 minutes for cleaning. At that time, the strong alkaline water
If the heating means H heats AL at about 40 ° C., while the aeration stirring means P convects and agitates the strong alkaline water AL in the permeation / pre-washing means 3, the tableware D after eating
Since it is strongly washed, dirt such as oil and fat, protein and starch can be easily removed.

Then, there is a cleaning / rinsing means 4 for jetting the strong alkaline water AL (see FIG. 2). This cleaning / rinsing means 4 is set after the above-mentioned permeation / pre-cleaning means 3, and another part of the strong alkaline water AL is 4 to 4 parts.
It is a rinsing dish which is ejected for about 5 minutes to wash and rinse the dishes D such as dishes washed in the previous stage. At this time, as in a dishwasher, this strong alkaline water AL is heated by the heating means H at 70 to 80 ° C.
If the tableware D that has been warmed to a certain degree and washed in the previous stage is constantly spouted with fresh strong alkaline water AL like a shower, the effect of washing and rinsing is further enhanced. Finally, there is the sterilization means 5 using the strongly acidic water AC mentioned above. The sterilizing means 5 with the strong acid water AC is set in the latter stage of the washing / rinsing means 4 described above. The strong acid water AC is injected and the tableware D rinsed in the previous stage is immersed in the sterilization means 5. Is to instantly sterilize.

Therefore, as shown in FIG. 1, the cleaning / rinsing means 4 for jetting the strong alkaline water AL is replaced with the cleaning means 4
It may be divided into two, a and rinsing means 4b. First, the cleaning means 4a is set after the above-mentioned permeation / pre-cleaning means 3, and another part of the above-mentioned strong alkaline water AL is ejected for about 1 minute, and the permeation / pre-cleaning is carried out at the previous step. The tableware D such as a plate is washed. At this time, like a dishwasher,
When the strong alkaline water AL is heated to about 70 to 80 ° C. by the heating means H so that the fresh strong alkaline water AL is constantly ejected like a shower on the tableware D prewashed in the previous stage, The effect of the rinse is further enhanced. On the other hand, the rinsing means 4b is set after the rinsing means 4a, and another part of the strong alkaline water AL is added to the rinsing means 4b.
Rinse the dishes D such as dishes washed in the previous stage after being ejected for about a second. At this time, as in the dishwasher, the fresh strong alkaline water AL is constantly sprayed on the dishes D washed in the previous stage like a shower, so that the rinsing effect is further enhanced. Finally, there is the sterilization means 5 using the strongly acidic water AC mentioned above. The sterilizing means 5 with the strong acidic water AC is set in the latter stage of the washing / rinsing means 4 or the rinsing means 4b, and the tableware D rinsed in the former stage after the strong acidic water AC is injected. It is soaked here, and it is instantly sterilized.

Next, the dishwashing and sterilizing method of the present invention will be described with reference to an embodiment thereof. First of all, tableware D after meal
About 10 minutes to 15 minutes of oil, fat, protein, starch and other sewage adhering to the
Soak and prewash by soaking for a minute. At this time, when the strong alkaline water AL is heated to about 40 ° C. and stirred with aeration, the tableware D becomes like laundry in a washing machine.
It is better because it can be prewashed more efficiently. Then, another part of the above strong alkaline water AL is jetted to the tableware like a shower for about 1 to 2 minutes, and the dish D prewashed in the previous stage is always washed with fresh strong alkaline water AL and rinsed. Furthermore, the effect of cleaning and rinsing may be improved. At this time, the effect of cleaning may be further improved by heating the strong alkaline water AL to about 70 to 80 ° C.

Therefore, it is advisable to separate the above washing and rinsing. That is, first, a part of the strong alkaline water AL is heated to about 70 ° C. and sprayed at ultrahigh pressure for about 1 minute on the tableware D prewashed in the previous stage. Next, the above strong alkaline water
Another part of AL should be sprayed on dish D like a shower for about 15 seconds to pour dish D. Finally, the tableware D rinsed in the previous stage is instantaneously sterilized by immersing it in a strongly acidic water AC of pH 3 or less, especially about 2.5 to 2.6. After that, it is said that the used strong alkaline water AL and strong acid water AC are mixed to neutralize and then drained. Ideally, these strong alkaline water AL and strong acidic water AC are obtained by electrolysis while injecting saline into water such as tap water.

EFFECTS OF THE INVENTION The dishwashing and sterilizing apparatus and method according to the present invention have the following great effects because of the above-mentioned effects. In other words, first, we eliminated the pollution of rivers, lakes and marshes and the coast with detergent. And since it does not heat the washing water to a high temperature, it is energy-saving. In addition, the time required for cleaning and sterilization has been shortened, resulting in labor savings.

Particularly, when this is used for business, the effect is great.
