This will be described with reference to FIG. FIG. 5 is a diagram showing a state in which the object α to be cleaned is immersed in the vapor phase 6 of the cleaning agent 5 by applying the present embodiment. In the figure, 9 and 9 ′ are openable / closable double-sided open / close lids attached to the upper opening 1 a of the cleaning tank 1. In this embodiment, when the object α to be cleaned is immersed in the vapor phase 6, the opening / closing lid 9,
After 9 ′ is opened and it is confirmed that the object α to be cleaned is immersed in the vapor phase 6, the opening / closing lids 9 and 9 ′ are closed and cleaning is performed. After the cleaning, the opening / closing lids 9 and 9 ′ are opened again, the object α to be cleaned is pulled up and dried. The difference from the first embodiment is the opening / closing lids 9 and 9 ′ attached to the upper opening 1a of the washing tank 1, but the opening and closing lids 9 and 9 ′ are used to clean the washing tank 1 during washing.
Since the emission from the upper opening 1a of the internal vapor phase 6 to the outside can be smaller than that in the first embodiment, the pressure and temperature of the vapor phase 6 in the cleaning tank 1 are set to be lower than those in the first embodiment. It is possible to raise the temperature, and it becomes possible to perform cleaning and drying in a shorter time, so that the cleaning agent 5 that has entered the gap of the object α to be cleaned is evaporated early to eliminate the occurrence of rust. The open / close lids 9 and 9 ′ are closed even when it is necessary to prevent the vapor phase 6 from escaping from the upper opening 1a even during the cleaning of the object α to be cleaned.

This will be described with reference to FIG. FIG. 6 is a diagram showing a state where the object α to be cleaned is immersed in the vapor phase 6 of the cleaning agent 5 by applying the present embodiment. In the figure, 10 is a heater installed in the vapor phase 6 along the inner peripheral surface of the intermediate portion below the condensing pipe 3 and the condensate gutter 4 inside the cleaning tank 1. In the present embodiment, after the article to be cleaned α is immersed in the vapor phase 6, the heater 10 is operated to raise the temperature of the vapor phase 6. By operating the heater 10, it becomes possible to clean and dry the vapor phase 6 at a temperature higher than that of the first embodiment, and the cleaning / drying can be performed in a shorter time.
Since it becomes possible to dry, the cleaning agent or the like 5 that has entered the gap of the object α to be cleaned is evaporated early to eliminate the occurrence of rust. In addition,
The heater 10 is operated even when it is necessary to heat the vapor phase 6 other than during the cleaning of the cleaning object α.
