８−２０６３８８号公報のような防振機構がある。2. Description of the Related Art In a conventional spin-drying washing machine, after the washing and rinsing steps, the clothes are biased in the spin-drying and spin-drying tub in the outer tub. During rotation, the outer tub containing the washing and dewatering tub vibrates particularly during resonance. Various anti-vibration mechanisms have been put to practical use to suppress this vibration. As an example of this, there is an anti-vibration mechanism as disclosed in JP-A-8-206388.

ャップを備えた構成となっている。In this vibration isolating mechanism, a cylindrical body having a lower end opening is provided on the spherical support surface of the outer tub, and a lower part of a hanging rod mounted on an upper part of an outer frame of the washing machine is inserted into the cylindrical body. A sliding member that slides on the inner wall surface of the cylindrical body is attached to the lower end of the hanging bar, and an impregnating member such as felt impregnated with lubricating oil is disposed above the sliding member. An anti-vibration spring is interposed between the moving member and the upper inner wall of the tubular body, and the lower end of the tubular body is provided with a cap having a small hole in order to prevent the lubricating oil from falling to the floor surface. I have.

り、両空間の空気の粘性抵抗によりダンパ作用が働き、
振動の抑制を行う。The principle of vibration suppression of the vibration isolating mechanism is that when the washing and spinning tub rotates during spinning, the outer tub vibrates up and down and rolls, and the sliding member moves up and down in the cylindrical body. Then, when the sliding member moves upward, the air in the upper space in the cylindrical body is compressed, the air flows out from the gap between the hanging rod and the through hole of the cylindrical body, and the cylindrical body flows into the lower space. Outside air flows in from a small hole of the cap attached to the lower part. As a result, the damper function works due to the viscous resistance of the air in both spaces,
Suppress vibration.

ている。When the sliding member is moved downward, the movement is reversed, and the vibration is similarly suppressed. Lubrication of the sliding portion between the inner wall of the cylindrical body and the sliding member is performed by an impregnating member such as felt in which lubricating oil is impregnated on the upper side of the sliding member. In addition, the lubricating oil that oozes out of the impregnating member and accumulates in the lower part of the cylindrical member also vibrates in the cylindrical member due to the vibration of the outer tank, and a rotational centrifugal force is applied to the lubricating oil, so that the lubricating oil rises on the inner wall surface and the sliding member moves. To keep the sliding member moving smoothly and keep the sliding resistance constant. And
The wear of the sliding member and the cylindrical body is reduced, and the durability is improved.

十分になり摺動部材や筒状体の摩耗が進むことになる。In the above prior art, when the vibration of the outer tub is large, the vibration of the cylindrical body also increases, and the lubricating oil accumulated at the lower part of the cylindrical body can rise to the sliding member. If the vibration is small, or if there is a lot of laundry and the sliding member is on the upper side of the tubular body, it is difficult to raise the lubricating oil to the sliding member. As a result, the wear of the sliding member and the cylindrical body is increased.

る。Next, the operation of the present invention will be described. At the time of washing, by putting clothes, washing water, etc. into the rinsing and dewatering tub 5, the anti-vibration spring 19 of the anti-vibration mechanism 2 receives a load and comes into close contact, and the sliding body 20 moves above the cylindrical body 16. I do. Then, at the time of dehydration, the load applied to the anti-vibration spring 19 decreases, and the anti-vibration spring 19 extends, and the sliding body 20 moves below the cylindrical body 16. The amount of movement at this time is determined in proportion to the rigidity of the vibration-proof spring 19 and the weight of the clothes absorbing water. In other words, when there are many clothes or clothes having good water absorption, the vibration-proof spring 19 is used.
Does not extend much, but the amount of extension of the anti-vibration spring 19 increases when there is little clothing or when the clothing has poor water absorption. As described above, during the washing and the spin-drying, the sliding body 20 moves about several tens mm in the tubular body 16. Therefore, in one embodiment of the present invention, the lubricating oil 29 accumulated in the lower part of the cylindrical body 16 is supplied from the small hole 27 of the cap 24 through the tube 30 by utilizing the pump action by the movement of the sliding body 20. Cylindrical body 16
Of the inner wall of the cylindrical body 16 and the sliding portion of the sliding member 23 are prevented from running out of oil.

As described above, the anti-vibration spring 19 contracts, and the state shown in FIG. 2 is obtained. This figure is a schematic view of the anti-vibration spring 19 being contracted when the lubricating oil 29 is present in the lower part of the tubular body 16. As shown in the figure, the air in the space above the sliding body 20 in the cylindrical body 16 is compressed, and the air in the space below the sliding body 20 expands. Thereby, the air in the upper space of the cylindrical body 16 moves from the small hole 25 provided on the side surface of the cylindrical body 16 through the tube 30 to the lower space of the cylindrical body 16 from the small hole 27 of the cap 24. . When the movement of the sliding body 20 is completed and the pressures in the upper and lower spaces of the tubular body 16 become equal, the lubricating oil 29
The liquid level of the tube 16 and the tube 3 is the same as in FIG.
Inside 0 is equal.

きな減衰力を付加することが可能になる。Next, in the dewatering step, the vibration isolating spring 19 is extended, and the state shown in FIG. 3 is obtained. As shown in the figure, the air in the space below the sliding body 20 in the cylindrical body 16 is compressed, and the sliding body 2 is compressed.
The air in the space above zero expands. Thereby, pressure is also applied to the lubricating oil 29 accumulated in the lower part of the cylindrical body 16,
The pressure connected to the small holes 25 and 27 and the tube 30 moves to an upper space where the pressure is low, and is dropped from the small holes 25 of the tubular body 16. This ensures that the lubricating oil 2
9 can exist in the upper space of the cylindrical body 16. In addition, as shown in FIG.
When the air moves from the lower space to the upper space, only the air moves in the cylindrical body 16, the small hole 27 of the cap 24, and the tube 30. In this state, when the outer tub 3 vibrates and the sliding body 20 vibrates up and down, the tube 30
Air flows back and forth between the cylindrical body 16 and the small holes 25 and 27 of the cap 24 via the air, and due to the viscous resistance of the air generated at that time, the damping force due to the air is added to the damping due to the sliding, so that a larger damping force is added. It becomes possible.

Is not limited to any fixing method such as fitting, screwing, welding or the like. Further, it is better that there is no gap between the hanging rod through hole 17 and the sliding body 20 of the tubular body 16 because the pressure in the tubular body 16 does not leak to the outside. However, a gap is necessary in manufacturing, and at least the cylindrical shape is required. It is sufficient that the diameter is smaller than the inner diameters of the small holes 25, 27 of the body 16, the cap 24, and the tube 30.

For example, the flow path of the lubricating oil 29 may be configured by using a member other than the tube 30 such as by fitting into the small hole 25 of FIG. Then, the flow path of the lubricating oil 29 may be provided inside or outside the cylindrical body 16 if there is no problem in the function of the vibration isolating mechanism 2.
