本発明は洗濯兼脱水槽を内装した外槽と、この外槽を本
体上部より懸垂支持する防振装置を備えた脱水洗濯機に
関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dehydrating washing machine equipped with an outer tub containing a washing and dehydrating tub, and a vibration isolator that suspends and supports the outer tub from the upper part of the main body.
一般にこの種の脱水洗濯機における防振装置は第3図お
よび第4図に示すような構成となっていた。Generally, a vibration isolating device in this type of dehydrating washing machine has a structure as shown in FIGS. 3 and 4.
すなわち、第3図においては、脱水時洗濯兼脱水槽内の
洗濯物の偏荷重によって外槽が上下に振動した場合、そ
の振動はスプリング41を介して緩衝管42と鉄板を絞
り成形したスプリング受43の円筒部44間の摺動抵抗
により防止していた。That is, in FIG. 3, when the outer tub vibrates up and down due to the unbalanced load of the laundry in the washing and dehydrating tub during spin-drying, the vibration is transmitted via the spring 41 to the buffer tube 42 and the spring receiver formed by drawing an iron plate. This was prevented by the sliding resistance between the cylindrical parts 44 of 43.
そして前記緩衝管42は弾力性を有するゴムにより製作
されているが、内径寸法の精度が出しにくいため、スプ
リング受43との締め代がばらつきやすく、このため摺
動抵坑が安定せず、振動吸収が不安定になるという欠点
があった。Although the buffer tube 42 is made of elastic rubber, it is difficult to achieve accurate inner diameter dimensions, so the tightness with the spring receiver 43 tends to vary, making the sliding resistance unstable and causing vibrations. The drawback was that absorption was unstable.
また前記ゴムは温度により硬度が変化して、高温では軟
かくなり、かつ低温では硬くなるため、夏は摺動抵抗が
小さく、冬は大きくなるというふうに摺動抵抗が不安定
になりやすい。Further, the hardness of the rubber changes depending on the temperature, becoming soft at high temperatures and hard at low temperatures, so the sliding resistance tends to be unstable, with the sliding resistance being small in summer and increasing in winter.
そしてまたこの構成によれば、緩衝管42とスプリング
受43間の摺動によりゴム製の緩衝管42が摩耗しやす
く、耐久性に欠けるとともに、摩耗により締め代が小さ
くなって摺動抵抗が小さくなるという欠点を有していた
。Furthermore, according to this configuration, the rubber buffer tube 42 is easily worn out due to sliding between the buffer tube 42 and the spring receiver 43, resulting in a lack of durability, and the wear reduces the tightening margin, resulting in low sliding resistance. It had the disadvantage of being
この第3図の欠点を解決するために第4図に示すような
防振装置が考案されている。In order to solve the drawbacks shown in FIG. 3, a vibration isolating device as shown in FIG. 4 has been devised.
すなわち、球面部45より下方に、緩衝管42に相当す
る円筒部46を合成樹脂で一体に形成して摺動体47を
構成している。That is, below the spherical part 45, a cylindrical part 46 corresponding to the buffer tube 42 is integrally formed of synthetic resin to constitute the sliding body 47.
そしてロツド48の下側は座金49の上に弾力性を有す
るゴムパッキング50を設け、かつこのゴムパッキング
50の外周にはリツプ51を形成し、そしてゴムパッキ
ング50の上側にはオイルを含浸させたフエルト52を
設け、このフエルト52の上にはスプリング53を受け
るスプリング受54を設けている。A resilient rubber packing 50 is provided on the washer 49 on the lower side of the rod 48, a lip 51 is formed on the outer periphery of the rubber packing 50, and the upper side of the rubber packing 50 is impregnated with oil. A felt 52 is provided, and a spring receiver 54 for receiving a spring 53 is provided on the felt 52.
そしてこの構造におけるゴムパッキング50のリツプ5
1は摺動体47内の空気を密封し、ロツド48と球面部
45内のボス55に形成した穴56との隙間よりゴムパ
ッキング50がロツド48とともに上下に往復運動する
とき、摺動体47内の空気が流出入して空気ダンパーの
作用をなし、防振を行なっていた。And the lip 5 of the rubber packing 50 in this structure
1 seals the air in the sliding body 47, and when the rubber packing 50 reciprocates up and down with the rod 48 through the gap between the rod 48 and the hole 56 formed in the boss 55 in the spherical part 45, the air inside the sliding body 47 is sealed. Air flows in and out, acting as an air damper and providing vibration isolation.
しかしながらこの構成によれば、洗濯兼脱水槽が脱水時
に高速回転する回転数と同じストロークだけ前記ゴムパ
ッキング50が上下に往復運動するため、フエルト52
に含浸させたオイルが上下に飛ばされる。However, according to this configuration, since the rubber packing 50 reciprocates up and down by the same stroke as the rotation speed at which the washing and dehydration tub rotates at high speed during dehydration, the felt 52
The oil impregnated in the water is sprayed upward and downward.
すなわち円筒部46の上部内壁までオイルが飛散してし
まい、その結果オイルが有効に潤滑しない。That is, the oil scatters to the upper inner wall of the cylindrical portion 46, and as a result, the oil does not lubricate effectively.
また前記ゴムパッキング50は上下ストローク運動が激
しいため、わずかの量のオイルがゴムパッキング50の
リツプ51を通過したとしても多量のオイルが下側に流
れ落ちることになる。Furthermore, since the rubber packing 50 undergoes intense vertical stroke movement, even if a small amount of oil passes through the lip 51 of the rubber packing 50, a large amount of oil will flow downward.
このようにフエルト52に含浸できる程度の粘度の低い
オイルが飛散する状態で長期使用された場合、オイル切
れが発生し、その結果、摩擦抵抗が急激に高くなり、ゴ
ムパッキング50が摩耗して密封できなくなるという問
題点を有していた。If the felt 52 is used for a long period of time in a state where oil with a low viscosity that can be impregnated is scattered, the oil will run out, and as a result, the frictional resistance will increase rapidly, causing the rubber packing 50 to wear out and seal. The problem was that it was impossible to do so.

るものである。As described above, according to the present invention, a receiver for receiving a spring is attached to the lower end of the rod, a packing is provided on the outer periphery of the receiver, this packing has elasticity, and the above-mentioned forming an upper lip and a lower lip that contact the inner wall of the sliding body; sealing a lubricant between the upper and lower lips;
The packing is made to slide vertically between the inner wall of the sliding body, and its vibration isolation is achieved by letting air in the sliding body flow in and out through the gap between the rod and the spherical part when the packing reciprocates up and down with the rod. This eliminates the air damper effect, making it more effective. Also, the packing prevents the lubricant from flowing up and down, which prevents the packing from wearing out due to lack of oil, which was the case in the past. As a result, the durability can be improved, and since the receiver serves both as a spring receiver and a packing retainer, the structure can be simplified, and has various other excellent features. It is.
