Abstract

PURPOSE:To increase the washing capability of a continuous washing machine by causing a drum to rotate more than one turn, in addition to the oscillating motion thereof within the predetermined angular range, when the drum rotates in a direction not to shift a wash, and dropping the wash after scooping with the rear side of a scoop. CONSTITUTION:In a continuous washing machine having a scoop 14 for shifting a wash 21 to an adjacent drum during the normal rotation of a drum 11 while not shifting the wash 21 during the reverse rotation, even when the wash 21 is scooped, the drum 11 repeats oscillating rotation for the predetermined time in both normal and reverse directions at a phase angle (450 degrees or less) outside the range of shifting the wash 21. Thereafter, the wash 21 is shifted to an adjacent drum via a carrying process. In addition to the process of the oscillating rotation, a process is provided for causing the rotation of the drum 11, for example, by 660 degrees in a reverse direction. In this case, the wash 21 is lifted with a beater 31 and subjected to a rotating squeezing and rinsing process. Then, the wash 21 is scooped with the rear side of the scoop 14 up to the high position of the drum 11, and dropped for beating washing. All the foregoing processes are repeated before finishing a washing process.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for washing a continuous washing machine in which a drum is oscillated.

0002

2. Description of the Related Art FIG. 5 shows a continuous washing machine conventionally proposed in Japanese Utility Model Publication No. 61-1903, in which the articles to be washed are conveyed from a feeding conveyor C to a feeding chute or a hopper H.
Then, it is thrown into the drum 1 of the stopped first tank. Further, an appropriate amount of detergent and other additives may be added to the first tank together with the items to be washed, or an injection port or valve may be provided in either the second tank or the subsequent layer and the additives may be added individually or simultaneously.

In FIG. 5, water is supplied from the washing water inlet 17 to the bottom of each fixed tank 2'', 2', 2 to be washed 21, 21',
21'' and enters the contaminated wash water tank 16 as a continuous flow countercurrently to the contaminated washing water tank 16.The washing operation is performed by discharging an appropriate amount of the laundry into a plurality of drums 1, 1', 1'' connected in series. The drum is filled with detergent and other additives as shown in FIG. 7(a).
As shown in FIG.
When transferring the items to be washed from the drum 1' to the second drum 1', the procedure shown in
It is carried out by unidirectional rotation of at least 270 degrees or more as shown in b).

[0004] This full rotational movement of the drum, which is oscillated and transferred, is conveniently carried out by a sun gear mechanism 13, 13' connected to a motor 15 with a reduction gear for driving the drum, which is installed outside the drum unit, and by a variable speed clutch mechanism, which is known per se. can. The transfer action of the objects to be washed between adjacent tanks shown in FIGS.
4', 4'' make a complete rotation in one direction of at least 270 degrees, and the items to be washed are scooped up in each drum space, passed through the flange portion 11, and transferred to the second tank.At this time, the washing water is are scoops 4, 4', 4'' and auxiliary plates 5, 5', 5
``It escapes through the slit between.

In addition, in the above structure, instead of swinging 270 degrees, the drum is continuously rotated a certain number of times in the direction opposite to the direction of rotation in which the washing object 21 is transferred, as shown in FIG. There is also a method of washing by lifting and dropping the clothes behind the scoop 4. In this case, the object 21 to be washed falls only once per rotation of the drum.

[0006]

[Problems to be Solved by the Invention] As mentioned above, if the washing object is massaged only by the oscillating motion of the drum, the mechanical action exerted on the washing object is small, and it is difficult to wash the object with a large degree of dirt. The drawback was that it couldn't be washed properly. In addition, in the washing method where the drum is repeatedly lifted and dropped on the back of a transfer scoop, the drum rotates in a fixed direction, which causes the items to be washed to become twisted and tangled, making it difficult to loosen them in subsequent processes. This resulted in the need for a large number of manpower. The present invention has been proposed to solve the above-mentioned conventional problems.

[0007]

[Means for Solving the Problems] Therefore, the present invention provides a drum having an inlet and an outlet for washing items at both ends thereof, a partition plate that divides the inside of the drum, and a partition plate that divides the inside of the drum into sections to be washed. A device for scooping up and transferring objects, a supply device for supplying washing water, rinsing water, etc. into the drum, and a drainage section for discharging the washing water, rinsing water, etc. in the drum to the outside,
In a continuous water washing machine, the laundry is sequentially transferred from the input port to the output port, and washing water, rinsing water, etc. are passed through the washing machine to continuously wash, rinse, etc. the drum. a rotational movement without movement of less than 450° in the direction;
In addition to the above-mentioned rocking angle of 450 degrees or less in the rotational direction in which no transfer is performed, a rotational movement of one rotation or more is performed, and this is repeated alternately, so that the washing is carried out by combining the rocking movement and the lifting and falling movement of the object to be washed. It is intended to be used as a means to solve problems.

[0008]

[Function] When washing in the same tank, in addition to the conventional 270-degree swinging motion of the drum, when the drum rotates in the direction in which no transfer is performed, it performs an additional rotational motion of one or more rotations (360 degrees or more). At this time, lift the item to be washed behind the scoop and then let it fall. By such means, the items to be washed are alternately massaged by the swinging of the drum and beaten by being lifted by the scoop and dropped from a high place.

As described above, the present invention adds a dropping motion from a high position to the conventional scrubbing using a rocking motion to strengthen the scrubbing, thereby increasing the mechanical action and improving the cleaning performance. Also, since the rotation is not in a fixed direction but in a swinging motion, there is no chance of the laundry being tangled.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIGS. 1 to 4 show embodiments of the present invention. First, in FIGS. 1 and 2, reference numeral 11 is a drum, which is a series of drums that can be separated into individual tanks, or one drum consisting of two or more tanks, each of which is separated by partition plates 30 and 30'. It is made up of things that exist. 14 is a scoop fixed to the drum 11 and the partition plates 30, 30', and when rotated in the normal direction, the item 21 to be washed can be sent to the adjacent tank, and when rotated in the reverse direction, even if the item 21 to be washed is scooped up, other It has a shape that prevents it from being transferred to the tank. A beater 31 is fixed to the drum 11 and the partition plates 30, 30'. In addition, in FIGS. 1 and 2, four beaters 31 are attached on the opposite side of the scoop 14, but they can be attached at any position.
You can also attach any number of them. Further, when the drum 11 rotates, the scoop 14 and the beater 31 rotate as one. Note that the object to be washed 21 exists at the bottom of the drum 11 together with washing water (not shown).

Now, as shown in FIG. 3(a), the drum 11
When it performs 360° forward rotation from the state (A), the object 21 to be washed is scooped up by the scoop 14 and transferred to the next tank [(A)→(B)→(A')].

For this reason, in a continuous water washer having a scoop 14, the oscillating rotation of forward and reverse rotation is repeated for a certain period of time at a phase angle at which the object to be washed 21 is not normally transferred, and then the object to be washed is transferred to the adjacent tank. is being sent. As shown in FIG. 4(b), the phase angle at which the phase is not transferred is considered to be a maximum of 450 degrees, but it is generally around 270 degrees to 300 degrees.

[0013] In this embodiment, forward rotation is 300° and reverse rotation is 66°.
The rotation and rocking control of the drum at 0° is shown in Figure 3 (
c) and Fig. 4(c). First, Fig. 3(a)
), the drum 1 rotates 360 degrees in the normal direction, and the object 21 to be washed is transferred to the state (A) or (A').

Now, as shown in FIG. 3(c), when the drum 11 rotates in the reverse direction in which the laundry object 21 is not transferred, first (
In the range from a) to (d) to (e), the object 21 to be washed is lifted and rotated by the beater 31 and massaged, as in the conventional rocking motion. Further, in the range from (F) to (G), the object 21 to be washed is scooped up to a high position on the drum by the back side of the scoop 14, and is washed by being beaten by falling. Further, in the range from (ch) to (c), the beater 31 performs massaging. In other words (a)
→ (d) → (e) → (f) → (g) → (ch) → (c) By reversing the drum 11 by 660 degrees, the object to be washed 21
is lifted once and then falls.

Next, as shown in FIG. 3(b), the drum 11 performs a normal rotation of 300° in the order of (c)→(li)→(a). As a result, the object 21 to be washed is lifted and rotated by the beater 31, and the object 21 to be washed is massaged and washed as described above.
A twist or twist in one direction given to 1 can be undone. Next, drum 11 is reversed 660°, and drum 1 is rotated 660°.
The normal rotation of 300° in step 1 is repeated several times until the next transfer, and the laundry object 21 is washed.

By the way, the normal rotation angle of the drum 11 is possible as long as it is 450° or less as described above, but the reverse rotation angle is at least one rotation (360°) above the normal rotation angle. The angle is the sum of .

Next, FIGS. 4(a), (b), and (c) show normal rotation 45.
An example is shown in which the angle is 0° and the reverse is 810°. First, transfer [
(i)→(ro)→(i')] From the state of (i), the drum 11 rotates 360° forward, and the object to be washed 21 is scooped up by the scoop 14 and transferred to the next tank. [Figure 4
(a)].

Next, as shown in FIG. 4(c), the drum 11 rotates in the reverse direction from the state shown in (a) immediately after the transfer so that the object 21 to be washed is not transferred. First, in the range of (i) → (ni) → (ho), the object 21 to be washed is lifted and rotated by the beater 31.
Massage is performed. Further, in the range from (to) to (to) to (chi), the object 21 to be washed is scooped up by the back side of the scoop 14 to a high place on the drum and falls, thereby being beaten and washed. Next, in the range from (chi) to (ri), the beater 31 performs massaging. Again (ri)→
Although it is scooped up by the back surface of the scoop 14 in the range (a), the object 21 to be washed does not fall, the drum stops at (a), and then rotates forward [FIG. 4(b)].

As shown in FIG. 4(b), the drum 11
It rotates 450 degrees in the normal direction as follows: ha (ha) → (nu) → (ru) → (i). At this time, the object 21 to be washed is lifted and rotated by the beater 31, and the object 21 is massaged and washed, and as described above, the object 21 to be washed is lifted and rotated.
A twist or twist in one direction given to 1 can be undone.

Next, the drum 11 is reversed 81 in FIG. 4(c).
0°, and the forward rotation of the drum 11 of 450° in FIG. 4(b) is repeated several times until the next transfer is performed to wash the laundry object 21.

Effects of the Invention As explained in detail above, in the present invention, when washing in the same tank, in addition to the rocking motion, lifting and falling motions behind the scoop are combined. It is possible to effectively add both of
Cleanability can be improved by about 20% compared to the conventional method. This means that the washing time can be shortened compared to conventional machines, and productivity can be improved. In addition, in the case of unidirectional rotation washing, there is a problem that long items such as sheets may become twisted or tangled in the tank, requiring a great deal of manpower to loosen them in the subsequent process. High cleaning efficiency is possible without any tangles.
