However, the endoscope cleaning and disinfecting apparatus disclosed in the above publication circulates again the cleaning liquid used for cleaning the endoscope and ejects the cleaning liquid toward the ceiling surface of the cleaning tank. Therefore, if the cleaning solution contains a large amount of contaminants such as bacteria, the contaminants may be sprayed on the ceiling surface together with the circulating cleaning solution.

[0005] When the jetting pressure of the cleaning liquid jetted from the ceiling surface cleaning nozzle is low, contaminants such as bacteria adhering to the ceiling surface cannot be completely washed away, or the cleaning liquid cannot be washed out. In the rinsing step for washing off the cleaning agent, there is a possibility that the detergent attached to the ceiling surface cannot be sufficiently washed away.

[0006] In the endoscope cleaning and disinfecting apparatus, it is necessary that the ceiling surface of the cleaning tank is kept clean. Otherwise, contaminants such as bacteria adhered to the ceiling surface may enter the cleaning tank. It may adhere to the set endoscope and re-contaminate the endoscope that has been thoroughly cleaned and disinfected.

Therefore, in order to solve the above-mentioned problem, in the endoscope cleaning / disinfecting apparatus disclosed in Japanese Patent Application Laid-Open No. 9-164117, in the cleaning step, the cleaning tank is not cleaned by the cleaning tank cleaning means. In the step performed after the cleaning step, the cleaning tank is cleaned by the cleaning tank cleaning means, thereby reliably removing dirt attached to the ceiling surface of the cleaning tank, and contaminating the endoscope with the dirt attached to the ceiling surface. Has solved the problem.

However, the area of the wall surface and the ceiling surface of the cleaning tank is large, and the cleaning liquid cannot be sprayed uniformly over the entire surface. There is a problem of complexity.

The present invention has been made in view of the above circumstances, and an object thereof is to surely disinfect a wall surface, a top cover, and the like in a cleaning tank, and to simplify the apparatus. An object of the present invention is to provide an endoscope cleaning / disinfecting apparatus.
