The cleaning liquid is sprayed to the object to be cleaned in the basket by the nozzle, the cleaning liquid is stored in the cleaning tank to immerse the basket, and the cleaning is performed by the high-pressure jet jet from the nozzle, and after a predetermined time has elapsed, the cleaning liquid is discharged from the nozzle. Is stopped and the cleaning liquid stored in the cleaning tank is discharged back to the cleaning liquid circulation tank and the cleaning liquid adhering to the object to be cleaned is cut off by air blow. At this time, the air in the closed cleaning tank is sucked and discharged by operating the mist removing ventilation device.

After the cleaning process is completed, a rinse is sprayed from a nozzle onto the object to be cleaned in the rotating basket in the cleaning tank, the rinse is stored in the cleaning tank to immerse the object to be cleaned, and the nozzle Rinsing is performed by a high-pressure jet jet from the nozzle, the injection from the nozzle is stopped after a lapse of a predetermined time, and the rinse stored in the cleaning tank is discharged to the rinse circulation tank to complete the return rinse step. Performing precision cleaning by blowing the object to be cleaned this re <br/> Nsu process complete after ionized water (pure water) is injected from the ion water injection nozzle.
After the rinsing step is completed, the object to be cleaned in the rotating basket is blown with hot air to dry it, and the cleaning cycle is completed. At this time, as in the case of draining the cleaning liquid, the mist removing ventilator is operated to perform hot air drying.

Examples of the cleaning agent used in the above cleaning include an aqueous alkaline cleaning agent and a neutral cleaning agent. When a non-rinsing type cleaning agent is used and sometimes the cleaning liquid stored in the cleaning liquid circulation tank is used for the rinse circulation. The water supplied to the tank is supplied to the circulation tank for cleaning liquid by a pump, and the above cleaning agent is added to the tank to adjust the concentration to a predetermined concentration (for example, 3.0 to 10.0%). The rinse contained in the rinse circulation tank has the same concentration as that of the cleaning liquid contained in the cleaning liquid circulation tank and has a reduced concentration (for example, 0.5 to 1.0).
%), And a cleaning agent is added to obtain a cleaning solution, and the concentration is adjusted to a predetermined concentration.

Means for discharging and returning the cleaning liquid and rinse stored in the above-mentioned cleaning tank to the tank include gravity falling due to a difference in height or forced suction by a pump. These are a cleaning tank, a circulating tank for cleaning liquid and a rinse. It is selected as appropriate according to the positional relationship of the installation height of the circulation tank for use. or,
In the case of drainage by natural fall, the number of drainage outlets and the size of drainage outlets shall be set appropriately in order to shorten the drainage time.

A cleaning apparatus for carrying out the above-mentioned cleaning method comprises one cleaning tank, one cleaning liquid circulation tank, and one cleaning liquid circulation tank.
A cleaning circulation tank is provided, and a basket containing an object to be cleaned is rotatably supported inside the cleaning tank, and is configured to rotate in the forward and reverse directions by a driving unit installed outside. . In addition, a nozzle for spraying the cleaning liquid and the rinse is housed and installed in the cleaning tank, the cleaning liquid adhering to the object to be cleaned, an air blow with a heater for draining and drying the rinse, and a mist for sucking and discharging the air in the cleaning tank. A removal ventilator is installed in communication. Further, sensors for detecting the rising and falling water levels of the cleaning liquid or rinse stored in the cleaning tank are attached to the upper and lower parts of the cleaning tank. The lower water level detection is not limited to the sensor, and may be managed by a timer.

The cleaning liquid circulation tank and the rinse circulation tank are connected to each other via a pump so that water is supplied from the rinse circulation tank side to the cleaning liquid circulation tank side. In order to spray the cleaning liquid and the rinse stored in the tank from the nozzles arranged in the cleaning tank, the tanks and the nozzles are connected to each other via a pump, and valves are attached to the respective pipelines. The other liquid is prevented from flowing in. In addition, the outlet of the cleaning tank and the tank are connected to each other so that the cleaning liquid or rinse stored in the cleaning tank and returned to the respective tanks can be returned.Solenoid valves are installed on the upstream side where both pipes join. Therefore, the opening and closing of the return pipe is controlled. When returning the cleaning solution or rinse stored in the cleaning tank to both tanks, either drainage caused by natural fall when the tank is installed lower than the cleaning tank or forced drainage by a pump. Although it is good, if the tank is installed at the same height as or above the cleaning tank, forced drainage by a pump will be used and the pump will be installed in the middle of the drainage pipe.

Further, the circulation tank for cleaning liquid and the circulation tank for rinsing are separated from the positions of the return pipes from the cleaning tank and the positions of intake of the liquid to be sent from these tanks to the nozzles in the cleaning tank, and the inside of the tank is internal. Is partitioned by a partition plate so that the liquid purified to some extent is supplied to the nozzle. Furthermore, both tanks contain cleaning liquid,
A heater for heating the rinse to a predetermined temperature is attached.

Furthermore, the above-mentioned cleaning liquid circulation tank may be equipped with an oil / fat recovery means consisting of a filter and an oil / water separator, and the rinse circulation tank may be equipped with a purification means consisting of a filter and activated carbon. It is also possible to connect an ion exchanger to spray the ionized water generated from the ionized water jet nozzle onto the object to be cleaned. Since the cleaning liquid and rinse are each collected and circulated and used, the oil and fat degreased from the object to be cleaned by the cleaning are returned to the tank together with the cleaning liquid.The oil and fat is recovered by the filter and the oil-water separator. By equipping the circulation tank for cleaning liquid with the means, it is possible to collect and purify. Also, the rinse can be cleaned by equipping it with a filter and a purifying means consisting of activated carbon, since the rinse naturally becomes dirty when it is circulated and used for a long period of time.

[0014]

According to the above-mentioned cleaning method, the object to be cleaned is accommodated in the rotating basket provided in the cleaning tank, and the basket is rotated in the forward and reverse directions while spray cleaning, immersion cleaning, and The high-pressure jet jet cleaning can clean every corner even where it is difficult to clean. And since the cleaning agent is an aqueous cleaning agent, the cleaning solution and rinse can be purified and reused.

At the end of the washing process and the end of the rinsing process, air blow (hot air blow in the case of rinsing) is performed while rotating the basket respectively, so that the liquid is quickly drained and quick drying is possible. Therefore, a series of cleaning time can be shortened.

The cleaning device comprises one cleaning tank and two tanks (cleaning solution and rinse), and the object to be cleaned is stored in a rotating basket in the cleaning tank while the liquid from the tank is stored. Since the supply is switched to perform cleaning, rinsing and drying, downsizing of the entire apparatus is achieved.

By providing the tank for storing the cleaning liquid with the oil / fat recovery means and the tank for storing the rinse with the cleaning means, it is possible to prolong the period of use of the cleaning liquid and the rinse that are recovered and circulated. . Further, when the purifying means is one in which an ion exchanger is assembled, precision cleaning can be performed by spraying and rinsing the ionized water generated thereby with the object to be cleaned.

Further, when the drainage from the cleaning tank to the tank is forced drainage by the pump, the drainage time can be shortened significantly as compared with the drainage time due to natural fall, whereby the switching time from cleaning to rinse is shortened. The time can be shortened, the time for one cycle can be shortened, and the installation location of the tank can be positioned higher than the cleaning tank.
