It has
又一方、環状凹所７の内周面には第２のシール部材２０
が嵌着されており、このシール部材２０は金属補強環１
１の外周面と密封摺動可能に径方向内方でかつ上方に向
って伸びているゴム状弾性材製シールリツプ２１を備え
ている。On the other hand, a second seal member 20 is provided on the inner peripheral surface of the annular recess 7.
is fitted, and this sealing member 20 is attached to the metal reinforcing ring 1.
The sealing lip 21 is made of a rubber-like elastic material and extends radially inwardly and upwardly so as to be able to seal and slide on the outer peripheral surface of the rubber-like elastic material.
本考案は上述した構戊を有する結果以下に述べる様な作
用効果が期待出来る。As a result of the present invention having the structure described above, the following effects can be expected.
金属補強環１１に設けられた連結穴１２に排水ホースを
連結することによりケーシング１内への水の漏洩を防止
できると共に、槽５下の水で満される容積を小さくでき
る。By connecting the drain hose to the connecting hole 12 provided in the metal reinforcing ring 11, leakage of water into the casing 1 can be prevented, and the volume filled with water below the tank 5 can be reduced.
したがって、例えば脱水洗濯機に本考案の密封装置を使
用した場合には、ケーシングにホースを取付ける従来の
脱水洗濯機に比較し、洗濯用の水を極めて節約すること
ができる。Therefore, for example, when the sealing device of the present invention is used in a dehydrating washing machine, water used for washing can be significantly saved compared to a conventional dehydrating washing machine in which a hose is attached to the casing.
又、第２のシール部材２０を槽５側に固定し、金属補強
環１１の外周面と密封摺動させる態様としているため、
回転軸３及び槽５が回転していない静止状態においては
第２のシール部材２０のシールリップ２１は弾性力によ
り金属補強環１１の外周面に良く圧接して、良好な密封
を達或する。Further, since the second seal member 20 is fixed to the tank 5 side and slidably seals with the outer peripheral surface of the metal reinforcing ring 11,
In a stationary state where the rotating shaft 3 and the tank 5 are not rotating, the seal lip 21 of the second seal member 20 comes into good pressure contact with the outer circumferential surface of the metal reinforcing ring 11 due to elastic force, achieving a good seal.
一方、回転軸３及び槽５が回転すると第２のシール部材
２０も共に回転し、この際発生する遠心力により第２の
シール部材２０のシールリップ２１の金属補強環１１に
対する圧接力は弱められ、この結果、シールリツプ２１
と金属補強環１１との摺動抵抗が低下するため、密封装
置全体として摺動抵抗を低く押えることができるもので
ある。On the other hand, when the rotating shaft 3 and the tank 5 rotate, the second seal member 20 also rotates, and the centrifugal force generated at this time weakens the pressing force of the seal lip 21 of the second seal member 20 against the metal reinforcing ring 11. , As a result, the seal lip 21
Since the sliding resistance between the metal reinforcing ring 11 and the metal reinforcing ring 11 is reduced, the sliding resistance of the entire sealing device can be kept low.
更に、環状凹所７は、第２のシール部材２０により密封
されているために、排出穴６から流入する水の水面と第
２のシール部材２０のシールリップ２１との間に圧縮さ
れた空気が封じ込まれ、水がシールリツプ２１まで達す
ることがない。Further, since the annular recess 7 is sealed by the second sealing member 20, compressed air is generated between the water surface of the water flowing in from the discharge hole 6 and the sealing lip 21 of the second sealing member 20. is sealed and water does not reach the seal lip 21.
したがって、第２のシールリツプ２０のシールリツプ２
１は、水が砂等の異物を含む場合であっても損傷を受け
ることがなく、長期に渡って安定したシール性能が期待
できるものである。Therefore, the sealing lip 2 of the second sealing lip 20
No. 1 is one that will not be damaged even if the water contains foreign matter such as sand, and can be expected to have stable sealing performance over a long period of time.
更に又、第１のシール部材１０の金属補強環１１の一端
をのばして、第２のシール部材２０の密封摺動面を提供
するとともに排水ホース等の連結穴１２をも提供する構
或としているため、密封装置全体の構造が簡単で製造コ
ストが安価な密封装置とできたものである。Furthermore, one end of the metal reinforcing ring 11 of the first seal member 10 is extended to provide a sealing sliding surface for the second seal member 20 and also provide a connection hole 12 for a drainage hose or the like. Therefore, the sealing device as a whole has a simple structure and is inexpensive to manufacture.
