However, conventionally, this type of cleaning equipment
When the shield is opened as the object to be cleaned comes in and out, the cleaning chamber is communicated with the outside, and the solvent gas flows out and diffuses outside from the entrance and exit of the object to be cleaned.

Problems to be Solved by the Invention The present invention attempts to solve the above-mentioned problems.Even when objects to be cleaned enter and exit the cleaning device, communication between the cleaning chamber and the outside is cut off, and the solvent gas is removed. This is intended to prevent the items to be cleaned from flowing out and spreading outside through the entrance and exit.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides an introduction chamber into which the objects to be cleaned are introduced, a cleaning chamber in which the cleaning work is performed on the objects to be cleaned, and an outlet through which the objects to be cleaned are brought out to the outside. A chamber for moving objects to be cleaned is formed through a communication port in the upper part of the introduction chamber, cleaning chamber, and outlet chamber, and a chamber for moving objects to be cleaned is formed in the upper part of the introduction chamber, washing chamber, and outlet chamber, and a chamber for moving objects to be cleaned is formed adjacent to the chamber in the horizontal direction. A horizontal movement mechanism is formed to move the object to be cleaned to the top of each chamber, and a vertical movement table is formed in each chamber to place the object to be cleaned on the upper surface and move it from each chamber to the transfer chamber. Each of the movable tables has a support member projecting upwardly, and a cover that covers and seals a communication port between the transfer chamber and each chamber can be opened by pushing up the cover body with the support member.

Further, the vertically movable table may form a shield that can seal the communication port while the object to be cleaned is not placed in the movable chamber.

Operation Since the present invention is configured as described above, in order to clean the object to be cleaned, the object to be cleaned is first introduced into the introduction chamber and placed on the upper surface of the vertically movable table. When the vertically movable table is raised, the support body projecting upward from the vertically movable table pushes up and opens the lid that covers and seals the communication port between the moving chamber and the introduction chamber. Then, the vertically movable table moves into the moving chamber and positions the object to be cleaned within the moving chamber.
