Abstract

An interior cleaning device for a machine tool includes a pipe arranged inside a cover covering at least a periphery of a machining section of the machine tool, and a pump for supplying liquid into the pipe, the interior cleaning device being for ejecting liquid from the pipe and cleaning accumulated substances accumulated inside the cover, wherein the pipe includes a first pipe provided with a first ejection section for ejecting liquid or air into the cover, and a second pipe installed inside the first pipe and that is provided with a second ejection section at a part facing other than downward in a vertical direction.

First claim

The invention claimed is:

1. An interior cleaning device for a machine tool, said interior cleaning device comprising:
a pipe arranged inside a cover covering at least a periphery of a machining section of the machine tool, and
a pump for supplying liquid into the pipe,
wherein the pipe includes:
a first pipe provided with a first ejection section for ejecting the liquid or air into the cover;
a second pipe installed inside the first pipe and provided with a second ejection section at a part facing other than downward in a vertical direction, and

wherein
the interior cleaning device is configured to eject the liquid, which is supplied by the pump into the second pipe, through the second ejection section and the first ejection section to clean accumulated substances accumulated inside the cover, and
the first pipe further includes a hole for supplying air between the first pipe and the second pipe.

2. The interior cleaning device according to claim 1 , comprising:
a check valve configured to prevent the liquid or air from flowing into the pump from the second pipe.
