In conventional dehydrating/washing machines, a bearing cylinder as a shaft support is fixed to the bottom of a water receiving tank which is elastically suspended from an outer box, and a cylindrical dehydrating shaft is attached to this bearing cylinder via a ball bearing. It has a structure in which a rotary tank is supported rotatably, and a rotating tub serving as a washing tub and a dehydrating tub is supported at the upper end of this spindle. With this type of structure, the parts of the bearing cylinder are heavy, and other parts such as the water tank and rotating tank are made of plastic to make them lighter. The structure tends to have a long distance from the center of gravity of the vibration system in the vertical direction, which causes large vibrations, and the rolling noise of the balls caused by the ball bearings is large, resulting in a large amount of noise.

を劣化させる虞れが生ずる。 Therefore, to deal with this, the dehydration shaft is rotatably supported via a sliding bearing instead of a ball bearing, and
A configuration has been considered in which the upper end of this slide bearing is formed as a dewatering shaft and receives a thrust load from a large-diameter portion. Although this can significantly reduce vibration and noise, there is a risk that water leaking from the water tank will enter the sliding surface of the slide bearing and deteriorate the bearing performance.

This will be explained with reference to the figures. Reference numeral 1 denotes an outer box, inside of which a water receiving tank 3 serving as a water receiving chamber is elastically suspended via an elastic suspension mechanism 2, and a mechanical part 6 consisting of a shaft support part 4, a motor 5, etc. at the bottom of the water receiving tank 3. is fixed. 7 is a rotating tank that is rotatably arranged in the water receiving tank 3 and serves as a washing tank and dehydration tank; 8 is a stirring blade;
The bearing structure of the dewatering shaft 9 supporting the rotary tank 7 and the washing shaft 10 supported by the dehydrating shaft 9 and having the stirring blade 8 attached to its upper end will be described in detail below with reference to FIG. That is, 11 and 12 are cylindrical sliding bearings, which are made of, for example, porous sintered metal impregnated with oil. A substantially cylindrical dewatering shaft 9 is fitted into the portions 4a, 4a, and rotatably supported by these sliding bearings 11,12. 13,
13 is the shaft support portion 4 of these slide bearings 11 and 12.
An oil-immersed cylinder interposed between the outer circumference of the dehydration shaft 9 and the inner circumference of the shaft support part 4 in contact with each end face of the shaft, and the oil stored in this cylinder is supplied to the sliding bearings 11 and 12. . Reference numeral 14 denotes a connector that is press-fitted onto the upper end of the dewatering shaft 9 to constitute a large diameter portion, and the rotary tank 7 is fixed to a flange portion 14a formed at the upper end of this connector. Reference numeral 15 denotes a seal storage chamber shaped like a cylindrical container formed at the upper end of the shaft support portion 4, the upper end of which is connected to the bottom of the water tank 3;
A sealing member 16 is installed between the inner circumference of the connector 5 and the outer circumference of the connector 14, and a drain hole 17 is formed at the bottom of the seal storage chamber 15. Reference numeral 18 denotes an annular retaining protrusion protruding from the inner bottom of the seal storage chamber 15, which surrounds the upper end of the upper sliding bearing 11 slightly protruding into the seal storage chamber 15 with a predetermined gap. It is set up to do so. Reference numeral 19 denotes an annular oil-immersed zone, which is located between the outer periphery of the upper end of the slide bearing 11 and the holding protrusion 18.

く低減させることができる。 According to this embodiment with the above configuration, the dehydration shaft 9 is rotatably supported by the slide bearings 11 and 12, so vibration and noise are significantly reduced compared to the conventional one that uses ball bearings. In addition, it can be manufactured at low cost. Moreover,
Even if water were to leak between the connector 14 and the sealing member 16, the water would flow from the outer peripheral surface of the connector 14 to the upper surface of the washer 20, and during rotation of the dehydration shaft 9, the water would flow through the washer 20 due to centrifugal force. It is scattered from the outer circumference toward the inner circumferential wall of the seal storage chamber 15 of the shaft support part 4 and collected at the bottom of the seal storage chamber 15, and also flows down from the outer circumference of the washer 20 to the bottom of the seal storage chamber 15 while the dehydration shaft 9 is stopped. Eventually, the water will be drained out of the shaft support part 4 through the drain hole 17. Furthermore, even if water that has fallen onto the upper surface of the washer 20 slightly flows from the outer peripheral edge of the washer 20 to the lower surface side, the oil-immersed zone 19 is interposed between the washer 20 and the sliding bearing 11. Since the lower surface of the bearing is covered with an oil film, the water is repelled to the outer circumferential side and does not reach the sliding bearing 11 side. Therefore, it is possible to prevent water leaking from between the seal member 16 and the connector 14 from entering the sliding bearing 11 below the connector 14 and causing rust on the sliding bearing 11 and the dewatering shaft 9. This allows the bearing performance to be maintained well over a long period of time, and also eliminates the need to use materials with high corrosion resistance for the sliding bearing 11 and the dehydration shaft 9, making it possible to further reduce manufacturing costs. Furthermore, since the thrust load acting on the sliding bearing 11 from the connector 14 is equalized by the washer 20, it is of course more advantageous to improve the durability of the sliding bearing 11. Since oil is constantly supplied from the oil-immersed zone 19 between the sliding surfaces of
Thrust loads can be received with good lubrication, and wear of the slide bearing 11 and generation of sliding noise can be significantly reduced.

好に行うことができる。 FIG. 3 shows a different embodiment of the present invention, which differs from the previous embodiment in that a cover tube 23 made of, for example, Teflon resin is provided over the entire outer periphery of the oil-immersed zone 19, and has a height dimension approximately equal to the thickness dimension of the oil-immersed zone 19. The cover cylinder 23 is fitted so that the upper end portion of the cover cylinder 23 is in approximate contact with the lower surface of the washer 20. With this configuration, the cover tube 23 can more reliably prevent water from entering the oil-immersed zone 19, so water can almost completely prevent water from entering the sliding bearing 11 side, and the water can be prevented from entering the oil-immersed zone 19. Since scattering and evaporation of the oil can be prevented by the cover tube 23, the lubrication performance of the plain bearing 11 can be maintained for a long period of time.Furthermore, the oil-immersed zone 19 is in a sealed form, so that the oil inside is in a state of saturated pressure. Therefore, oil can be supplied between the slide bearing 11 and the washer 20 even better.

As described above, the present invention provides an oil-immersed zone on the outer periphery of the upper end of the uppermost sliding bearing provided on the shaft support, and the oil-immersed zone is provided between the sliding bearing and the large-diameter portion of the dewatering shaft. It is characterized by a structure in which a washer with a larger diameter than the oil-immersed zone is inserted, and it goes without saying that vibration and noise can be significantly reduced compared to those using ball bearings. It is possible to reliably prevent water from entering the sliding bearing side, preventing rusting of the sliding bearing and dehydrating shaft, and also supplying sufficient oil to the thrust load receiving surface of the dehydrating shaft, resulting in good lubrication. As a result, overall noise can be further reduced and the life of the bearing can be extended.
