本発明は、ドライクリーニング機の改良に関す
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in dry cleaning machines.
通常、ドライクリーニング機によつて衣料等を
洗濯する場合は、駆動源によつて回転する洗濯ド
ラム内に衣料等を入れ、低速回転で洗濯を行なつ
たのち、該洗濯ドラムを高速回転させ遠心力によ
り脱液を行なうが、その脱液時に衣料等が洗濯ド
ラム内に偏在していて均一に分布していないた
め、衣料等の偏荷重により大きな加振力が洗濯ド
ラムに発生して機械寿命を短かくするばかりでな
く、機械の振動が据付け地盤を通して周囲に伝播
して振動公害の一因となつているという欠点があ
つた。 Normally, when washing clothes etc. using a dry cleaning machine, the clothes etc. are placed in a washing drum that is rotated by a drive source, and after washing is done at low speed, the washing drum is rotated at high speed and centrifuged. The liquid is removed by force, but when the liquid is removed, clothes, etc. are unevenly distributed in the washing drum and are not evenly distributed, so a large excitation force is generated on the washing drum due to the uneven load of clothes, etc., which shortens the life of the machine. This not only shortens the length of the machine, but also has the disadvantage that the vibrations of the machine propagate to the surrounding area through the installation ground, contributing to vibration pollution.
これに対し、従来、行なわれている対策は、つ
ぎの3つに大別される。 Conventionally, countermeasures against this problem can be broadly classified into the following three types.
(i) 洗濯ドラム内の衣料等の偏荷重を低減させ
る。(i) Reduce the uneven load of clothes, etc. in the washing drum.
(ii) 機械の据付け地盤に対する振動を遮断する。(ii) Isolate vibrations to the ground where the machine is installed.
(iii) 据付け地盤を補強する。(iii) Reinforce the installation ground.
上記(i)の対策例としては、水平回転軸のクリー
ニンング機の場合、脱液前に洗濯ドラム内の衣料
等がほぼ1Gの遠心加速度を回転(バランス回
転)に、一定時間保持する対策があり、この対策
により衣料等の偏荷重をほぼ半減できるけれど
も、時々大きな偏荷重が発生する場合があつて、
十分な対策とはいえない。 As an example of countermeasures for (i) above, in the case of a cleaning machine with a horizontal rotating shaft, there is a countermeasure to maintain the centrifugal acceleration of approximately 1G of centrifugal acceleration of the clothes in the washing drum for a certain period of time before removing liquid. Although this measure can reduce the unbalanced load on clothing, etc. by almost half, sometimes a large unbalanced load may occur.
This is not a sufficient measure.
また、上記対策(ii)の例としては、ばねとダンパ
とで構成された防振架台により機械全体を弾性支
持したもの、あるいは洗濯ドラム部分のみを弾性
支持したものが知られている。この対策により機

面弾性支持された機械全体あるいは洗濯ドラム部
分の振動振幅は増大し、機械内の配管洩れ、締結
部分の緩み等の問題が発生し、この対策も十分な
ものとはいえない。 Further, as an example of the above-mentioned measure (ii), there are known ones in which the entire machine is elastically supported by a vibration-isolating frame composed of a spring and a damper, or in which only the washing drum portion is elastically supported. With this measure, the amount of vibration transmitted from the machine to the ground is reduced to a fraction of that of the conventional method, eliminating the problem of vibration pollution. However, on the other hand, the vibration amplitude of the whole machine or the washing drum, which is elastically supported, increases, and the machine Problems such as internal piping leakage and loosening of fastened parts occur, and these countermeasures cannot be said to be sufficient.
また、上記対策(iii)の例として、大きなコンクリ
ートブロツクの基礎上に機械を据付け、地盤の振
動を小さくする対策があるが、十分な防振効果を
得るがためには、基礎工事に要する経費が膨大な
ものとなるという欠点があつた。 In addition, an example of the above measure (iii) is to install the machine on the foundation of a large concrete block to reduce ground vibration, but in order to obtain a sufficient vibration-proofing effect, the cost required for foundation work is The disadvantage was that the amount of data was enormous.

In the figure, T indicates the time it takes for the washing drum to rotate once, and t indicates the time difference between the detection of the maximum vibration value and the detection of the reference point. From FIG. 5, the magnitude of the unbalanced load and the angle θ between the reference point and the unbalanced load are determined as follows.

P″はつぎのようにして求められる。 In Figure 6, F: Balanced load due to the liquid that entered chamber 2 (F = 0 in Figure 6) F': Balanced load due to the liquid that entered chamber 2' Kg, F'' :Balanced load (Kg) due to the liquid that has entered chamber 2'' As shown in Figure 7, clothing, etc. contains a large amount of liquid in the intermediate deliquing rotation, and the amount of unbalanced load is greater than when moving to the deliquing rotation. is big. In the example of the automatic balancing time schedule shown in Figure 8, the idea is to balance the unbalanced load at the time of transition to the dewatering rotation in advance at the intermediate dewatering rotation, and In order to balance the unbalanced load, each chamber 2,
Balance loads P, P′ due to the liquid put in 2′, 2″,
P″ can be found as follows.

(C×E)に1以下の定数をかけた値である。 This operation is continued two or three times if necessary, and when the residual unbalanced load becomes less than a specified value, a transition to liquid removal rotation is performed. Note that the periodic value here is not a constant value, but a value obtained by multiplying the first detected unbalanced load amount (C×E) by a constant of 1 or less.
脱液回転に移行後、衣料等に含まれている液体

By sending compressed air into each chamber 2, 2', 2'' through 18, liquid is carried out from each chamber.

In this case, calculate the amount of liquid to be put into each chamber 2, 2', 2'' from the above-mentioned values of the balanced loads F, F', F'',
Each liquid valve 17, 17', 17'' can be opened for a required period of time to allow liquid into each chamber to correct the imbalance.

The one-dot chain line shows the level of ground vibration when the present invention was implemented, and the two-dot chain line shows the level of ground vibration in the conventional case. As can be seen from this figure, according to the present invention,
The amount of residual unbalance is reduced to less than 1/5 compared to the conventional method, and the ground vibration level is reduced by more than 14 dB, completely solving the ground vibration problem.
