この考案は、洗浄液を収容した洗浄槽に、洗浄
液を加熱する加熱装置を設け、かつ、洗浄液の減
少を検出するようにした洗浄装置に関する。[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a cleaning device in which a heating device for heating the cleaning liquid is provided in a cleaning tank containing the cleaning liquid, and a decrease in the cleaning liquid is detected.
従来、工業製品等の被洗浄物を洗浄する洗浄装
置は、第３図に示すように構成されている。
Conventionally, a cleaning apparatus for cleaning objects to be cleaned, such as industrial products, is configured as shown in FIG.
すなわち、洗浄槽１にトリクロロエタン、フロ

に、減少した洗浄液２の液面を検出するリードス
イツチ型の検出器５が設けられている。 That is, a cleaning tank 1 contains a solvent such as trichloroethane or chlorofluorocarbon, or a cleaning liquid 2 such as water, an alkaline solution, or an acidic liquid, and the cleaning liquid 2 is placed at the bottom of the cleaning tank 1 in order to enhance the cleaning effect of the object 3 to be cleaned. A heating device 4 is provided for heating, and a reed switch type detector 5 is provided on the inner wall of the cleaning tank 1 to detect a decreased level of the cleaning liquid 2.
なお、洗浄効果をより高めるために、洗浄槽１
の底部に超音波洗浄機（図示せず）を設けられる
ことがある。 In addition, in order to further enhance the cleaning effect, cleaning tank 1
An ultrasonic cleaner (not shown) may be provided at the bottom of the container.
そして、洗浄液２が減少すると、所定の水位で
検出器５が動作し、その検出信号により、加熱装

報を出し、被洗浄物３の洗浄液２からの露出およ
び、洗浄槽１の空焚きを防止している。 When the cleaning liquid 2 decreases, the detector 5 operates at a predetermined water level, and depending on the detection signal, the power to the heating device 4 is cut off or an alarm to add the cleaning liquid 2 is issued, and the cleaning liquid 2 on the object 3 is This prevents the cleaning tank 1 from being exposed to water and from being heated dry.
ところで、前記従来の装置では、被洗浄物３の
洗浄時に被洗浄物３から出される洗浄残滓が、洗
浄液２の中あるいは上部に浮遊し、その洗浄残滓

By the way, in the conventional apparatus, cleaning residues discharged from the object to be cleaned 3 during cleaning of the object to be cleaned 3 float in or on top of the cleaning liquid 2, and the cleaning residues adhere to the detector 5.
そのため、検出器５が正常に動作しなく、洗浄
液２の減少を検出しないため、被洗浄物３が洗浄
液２から露出し、被洗浄物３が洗浄されない。 Therefore, the detector 5 does not operate normally and does not detect the decrease in the cleaning liquid 2, so the object 3 to be cleaned is exposed from the cleaning liquid 2, and the object 3 to be cleaned is not cleaned.
その上、加熱装置４により洗浄液２が空焚きの
現象になり、洗浄液２が分解して有害ガスを発生
する。 Moreover, the heating device 4 causes the cleaning liquid 2 to dry up, causing the cleaning liquid 2 to decompose and generate harmful gases.

Therefore, according to this invention, a proximity switch as a detector is provided in the cleaning liquid via an isolation sheet, so when the cleaning liquid that was in contact with the sheet runs out, the proximity switch is activated and the amount of cleaning liquid decreases. Detect accurately.
つぎに、この考案を、その１実施例を示した第
１図および第２図とともに、詳細に説明する。
Next, this invention will be explained in detail with reference to FIGS. 1 and 2 showing one embodiment thereof.
それらの図面において、第３図と同一記号は同
一のものを示し、異なる点はつぎのとおりであ
る。 In those drawings, the same symbols as in FIG. 3 indicate the same things, and the differences are as follows.

動作し、検出信号を出力する。 11 is a blank flange that is applied to the sheet 9; 12 is a circular insertion hole provided in the center of the blank flange 11; and 13 is a capacitive type that is inserted into the insertion hole 12 and whose tip is in contact with the sheet 9. This is a proximity switch, which is installed opposite to the cleaning liquid 2 through the sheet 9, and operates when the cleaning liquid 2 that has come into contact with the sheet 9 runs out, and outputs a detection signal.

つぎに、前記実施例の動作について説明する。 Next, the operation of the above embodiment will be explained.
いま、洗浄液２が十分にあり、その液面が検出
口６より上方の位置にある場合、近接スイツチ１
３は、シート９を介してシート９面に洗浄液２の
あることを検出し、近接スイツチ１３が正の動作
状態にある。 If there is enough cleaning liquid 2 and the liquid level is above the detection port 6, the proximity switch 1
3 detects the presence of the cleaning liquid 2 on the surface of the sheet 9 via the sheet 9, and the proximity switch 13 is in the positive operating state.
つぎに、洗浄液２が減少し、筒体７内に洗浄液
２が無くなると、近接スイツチ１３は空気層を検
出し、正の動作状態にならなく、逆の動作状態に
なる。 Next, when the cleaning liquid 2 decreases and there is no cleaning liquid 2 in the cylinder 7, the proximity switch 13 detects an air layer and does not enter the positive operating state, but enters the reverse operating state.
したがつて、その検出信号により、洗浄液２の
減少を表示し、加熱装置４への電力を遮断し、洗
浄液２を補充する。 Therefore, the detection signal indicates that the cleaning liquid 2 has decreased, the power to the heating device 4 is cut off, and the cleaning liquid 2 is replenished.
したがつて、前記実施例によると、近接スイツ
チ１３がシート９により洗浄液２に直接接触しな
いため、洗浄残滓が洗浄液２の中あるいは上部に
浮遊していても、その洗浄残滓が近接スイツチ１
３に付着しなく、近接スイツチ１３が洗浄液２の
液面を正確に検出し、被洗浄物３が洗浄液２から
露出したり、空焚き現象の生じることがない。 Therefore, according to the embodiment, since the proximity switch 13 does not come into direct contact with the cleaning liquid 2 due to the sheet 9, even if the cleaning residue is floating in or on top of the cleaning liquid 2, the cleaning residue will not reach the proximity switch 1.
3, the proximity switch 13 accurately detects the liquid level of the cleaning liquid 2, and the object 3 to be cleaned is not exposed from the cleaning liquid 2, and the dry heating phenomenon does not occur.
なお、シート９の厚みが大であると、近接スイ
ツチ１３がシート９を検出して動作するため、シ
ート９を検出しない程度の厚みのシート９を選定
する。 Note that if the thickness of the sheet 9 is large, the proximity switch 13 will detect the sheet 9 and operate, so a sheet 9 that is thick enough not to detect the sheet 9 is selected.
以上のように、この考案は、近接スイツチが減
少した洗浄液の液面を正確に検出することがで
き、被洗浄物の露出および空焚きを防止すること
ができる。
As described above, in this invention, the proximity switch can accurately detect the reduced level of the cleaning liquid, thereby preventing exposure of the object to be cleaned and dry heating.
