DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the overall structure of a continuous water washing machine according to an embodiment of the present invention, FIG. 2 shows the internal structure of the drum, and FIG. 3 shows the state of the line III--III in FIG. FIG. 4 shows IV-I in FIG.
FIG. 5 shows the state as viewed from the direction of the arrow V, and FIG.

In FIGS. 1 and 2, reference numeral 51 denotes a drum, which is composed of a series of separable tanks, or two or more tanks are constituted by one drum, and each tank is divided by partition plates 52 and 52 '. It is divided into multiple rooms. A scoop 53 as a transfer means is fixed over the drum 51 and the partition plates 52, 52 ', and the shape of the scoop 53 is such that when the drum 51 rotates normally, the object 54 to be washed is picked up and sent to the adjacent tank. Therefore, when the drum 51 is reversed, even if the washing object 54 is scooped up, it is not transferred to another tank.

A beater 55 is fixed to the drum 51 and the partition plates 52 and 52 '. Although four beaters 55 are attached to the opposite side of the scoop 53 in the one shown in FIG. 2, any number of beaters 55 may be attached at any position. Drum 5
When 1 rotates, the scoop 53 and the beater 55 integrally rotate. On the bottom of the drum 51, an article to be washed 54 exists along with washing water (not shown).

As shown in FIG. 1, fixed drums 56, 57 and 58 are provided outside the drum 51, and the fixed drum 5
Water supply and drainage, supply of detergent and the like to the drum 51 and heating are performed via 6, 57 and 58. In FIG. 1, 59 is an inlet for the article to be washed 54, and 60 is an outlet for the article to be washed 54.

The drum 51 is provided with a drum ring 61, and as shown in FIG. 4, the drum ring 61 is supported by a plurality of (four in the illustrated example) support rollers 62. A drum sprocket 63 is provided on the drum 51 near the charging port 59, and a frame 64 for holding the drum 51 is provided.
Is provided with a first geared motor 65 and a second geared motor 66 as drive motors. The first sprocket 6 is attached to the first geared motor 65 and the second geared motor 66.
7 and the second sprocket 68 are attached, and as shown in FIG. 3, the drum sprocket 63, the first sprocket 6
A silent chain 69 as a driving force transmission mechanism is wound around the 7 and the second sprocket 68. That is, the drum 51 is rotationally driven through the silent chain 69 by driving the first geared motor 65 and the second geared motor 66.

As shown in FIG. 5, the drum sprocket 6 is
3 is held by a pair of guide rollers 70, and the movement of the drum sprocket 63 in the direction of the rotation center axis is restricted.

The operation of the continuous type water washing machine having the above structure will be described with reference to FIGS. 6 to 8.

As shown in FIG. 6B, the drum 51 is normally rotated from the state (a) to the state (b) → (c), and from the state (d) to (e) → (e). When the state is reversed to the above state, the beater 55 cleans the object 54 to be washed (rocking washing). The rocking washing does not involve scooping up the article to be washed 54, and therefore a large driving force is not required to rotate the drum 51. Therefore, as shown in FIG. 6A, only the first geared motor 65 is driven in the forward and reverse directions (clockwise direction: CW and counterclockwise direction: CC) at the time of rocking washing.
W) to rotate the drum 51. Incidentally, FIG. 6 (a)
Medium t is the time during which the first geared motor 65 switches from forward rotation to reverse rotation. Further, as shown by a broken line in the drawing, it is possible to use the second geared motor 66 only during reverse rotation drive and stop the first geared motor 65 during reverse rotation.

As shown in FIG. 7 (b), the drum 51 is changed from the state (a ') to the state (b') → (d ') 36.
When 0 ° reverse rotation is performed, the object to be washed 54 is scooped up by the back side of the scoop 53 to a high place of the drum 51 and dropped, and is tapped to be washed (lifted drop washing). In the lifting drop washing, since the object 54 to be washed is picked up, the drum 5
A large driving force is required for one rotation. Therefore, in FIG.
As shown in (a), during the lifting and drop washing, the first geared motor 65 and the second geared motor 66 are simultaneously driven in reverse to rotate the drum 51.

As shown in FIG. 8B, from the state of the drum 51 in (a ″), (b ″) → (c ″) → (d ″) →
When the normal rotation is performed from the state of (e ") to (e"), the washing object 54 is washed by the beater 55 within the range of (a "), (b"), and (c "). (Ni ″),
Within the range of (e) and (e), the scoop 53 is scooped up and transferred to the next tank (transfer). At the time of transfer, since the object 54 to be washed is picked up from the middle (the state of "2"), the drum 5 is in the range of (2 "), (H"), and (H ").
A large driving force is required for one rotation. Therefore, in FIG.
As shown in (a), during transfer, the first geared motor 65
Is driven in the forward direction over the entire range, and (d "),
The second geared motor 66 is driven to rotate in the normal direction in the range of (e) and (e) to rotate the drum 51.

In the above continuous washing machine, when a large driving force is required to rotate the drum 51, the first geared motor 65 is used.
Also, since the second geared motor 66 is driven to change the driving force, even a driving motor having a small capacity can perform lifting drop washing and transfer which require a large driving force to rotate the drum 51. For this reason, the drive motor can be downsized, and maintenance is facilitated. Further, since the driving force of the first geared motor 65 and the second geared motor 66 is transmitted to the drum 51 via one silent chain 69, it is not necessary to adjust the drive timing of the first geared motor 65 and the second geared motor 66.

[0019]

The continuous washing machine of the present invention transmits the driving force of two driving motors to the drum through one driving force transmission mechanism, and one driving motor is used when a large driving force is not required to rotate the drum. The drive motor rotates the drum, and when a large drive force is required to rotate the drum, the two drive motors rotate the drum, so the drive motor with a small capacity can rotate the drum. .. As a result, the size of the drive motor can be reduced, cost reduction and labor saving operation can be performed, and maintainability can be improved.
