Fel、 、NiCu、 。(Example) An example of the present invention will be described below with reference to the drawings. FIG. 1 shows the basic structure of a gas laser device having an outlet 6 and a discharge lower. The sealed container 1 is filled with gas. During laser oscillation, a gas flow generated by the fan 3 passes through the wind guide 5, is cooled by the heat exchanger 4, and is then guided to the electrode 2. At this time, the dust generated inside the device is scattered by the high-speed gas flow, and deposits on the bottom of the container and on each component except during laser oscillation. Therefore, in order to clean these dusts, first the valve 9 is opened and the cleaning liquid is vigorously sprayed from the cleaning liquid outlet 6 installed for each part. The cleaning liquid blows away the dirt that has accumulated in various parts, flows along the inner surface of the sealed container and the wind guide to the discharge lower, and is discharged outside the sealed container. Among various gas laser devices, dust generated in an excimer laser device consists of fine fragments of metal members and insulators that constitute the device, and corrosion products generated when the metal members are corroded by the halogen gas used. This was confirmed by the inventor by actually investigating the interior of an excimer laser device in which oscillation experiments were repeatedly conducted. In particular, corrosion products generated when chlorine is used as a halogen element are chlorides (

However, metal chlorides include water, alcohols with 10 or less carbon atoms such as methyl alcohol and ethyl alcohol, and ketones with 10 or less carbon atoms such as acetone.

すれば固着した腐食生成物も簡単に溶解し洗い流せる。It has the property of being easily soluble in ethers having carbon atoms of 10 or less, such as dimethyl ether, and if these liquids are used as cleaning liquids, fixed corrosion products can be easily dissolved and washed away.

することができる。In addition, when using fluorine as a halogen element, the corrosion products that are generated are fluorides (FeF2゜NiF, Al2F, etc.) of the metal parts used inside the equipment.These fluorides absorb moisture. Since it rarely sticks, it can be easily washed off by simply spraying cleaning liquid on it. The cleaning liquid used at this time is not only metal chloride cleaning liquids such as methyl alcohol and ethyl alcohol, but also the pressure (0.1 Torr) used to reduce the pressure once to replace the gas in the gas laser device, and the pressure used to rotate the blower fan. The range in which the temperature rises when gas is flowed (room temperature to 6
By using a liquid that boils at 0℃), the cleaning liquid remaining inside the container can be easily vaporized by the basic operations of gas laser equipment such as replacing the gas and blowing air, and can be exhausted outside the equipment, making it easy to use the laser again. The time until oscillation can be shortened.

ない。Next, an embodiment of the air outlet suitable for the shape of the part will be described with reference to the drawings. Figure 2 shows a cleaning liquid outlet for wide parts such as electrodes, and the cleaning liquid can be sprayed evenly onto the electrode 2 and electrode support 8, and the wide parts can be cleaned evenly with this blower. can. FIG. 3 shows a cleaning liquid outlet for rotating parts such as a blower fan. When cleaning a rotating body such as the fan 3, by spraying the cleaning liquid while rotating at a low speed, the entire body can be cleaned with one cleaning liquid outlet, and as shown in Fig. 3, the tip of the outlet 6 is formed small. By using the outlet 6 having a similar structure, the fan 3 will not be damaged.

洗浄ができる。When the capacity of the airtight container 1 is small, when parts such as the heat exchanger 4 have a complicated structure, or when it is difficult to spray the cleaning liquid because it is in the shadow of other parts, the cleaning liquid outlet 6 can be opened while the discharge lower is closed. The inside of the apparatus can be cleaned by filling the closed container 1 with cleaning liquid until it is almost full and rotating the fan 3 to circulate the cleaning liquid. In addition, the dust removal net 11 can remove dust floating in the cleaning liquid while the cleaning liquid is being circulated. Next, stop the fan 3, open the discharge lower to discharge the cleaning liquid, and remove the dust. net 1
If the dust trapped in 1 is removed, the device can be cleaned without disassembling it.
