BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous washing machine.

[0002]

2. Description of the Related Art In a continuous washing machine, inner and outer drums are connected in the axial direction, and adjacent inner drums communicate with each other at a central opening. The inner drum is a washing tub that imparts movement to the laundry through the washing liquid. The inner drum is rotated to perform washing with each inner drum, and the inner drum is rotated in reverse to send the wash to the downstream inner drum. Stroking like In such a driving device for the inner trunk, one driving device drives the entire inner trunk, or each inner trunk is driven by one driving device. In the former case, each inner cylinder rotates at the same rotational speed. Also in the latter case, each inner trunk is rotating at the same rotational speed. Therefore, a wide variety of linens, for example, relatively less stains such as wrappers, sheets, bath towels, face towels, bath mats, gowns, etc .; Terrible things are also washed by constant speed rotation. Therefore, those having different degrees of dirt are classified and then washed for each class, and the washing time is changed.

[0003]

Problems to be Solved by the Invention The laundry is of the same type with respect to the removal of dirt from the laundry, and when washing a fixed amount continuously, even if each inner copper is rotated at a constant speed at the same rotation speed as described above. No problem. However, since the type of laundry varies depending on the type of laundry, the washing time has conventionally been changed to wash laundry having different types of soil removal. In the case of a single continuous washing machine, the same type of laundry is not always handled, and washing of different types of laundry such as dirt, cloth type, and clothing type is not performed. In such a case, in order to change the washing time, the washing time for normal rotation of the inner body is simultaneously changed, and the washing time is reversed for a predetermined time to send the laundry to the adjacent inner body. In this case, since the washing tubs are rotating at the same speed, if the other rotating speed is suitable for the laundry to be washed next, all the laundry being washed now has the same rotation speed. The rotation speed cannot be changed unless it is discharged from the continuous washing machine. Therefore, in this case, the rotation speed cannot be changed until the front and rear bundles of the preceding laundry have left the continuous washing machine.
There is a waste of spinning, and even after the rotation speed is changed, there is an inner drum that spins until the first bundle of laundry reaches the last inner drum.

[0004] Disregarding this, the continuous washing machine is operated at a rotation speed that is not suitable for other types of linen, even if the rotation speed is appropriate for a wide variety of laundry, and the washing is performed. The power is excessive but the linen is damaged, or the linen is not good but the cleaning power is insufficient.

[0005] The present invention provides a continuous washing machine in which laundry can be washed at an optimum rotational speed even when mixed laundry having different dirt, cloth quality, and shape is mixed, so that the laundry is always washed in each inner body. The purpose is to:

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a longitudinal sectional view of an embodiment of the present invention. The inner shell 1 made of a perforated plate and the drum-shaped outer shell 2 are concentric with each other and constitute a tank together. A hollow cylindrical journal portion 3 at the center of the inner body 1 is rotatably fitted to a bearing portion 4 of the outer body 2. A transfer opening 8 is formed at the center of the journal 3. The outer shell 2 is provided with a partition 6 in the axial direction so as to partition between both end plates 5. Part of the partition 6 communicates as shown in the flow of the cleaning step described later.

A ring gear 9 is fixed to the outer periphery of the inner body 1, and a pinion 11 meshing with the ring gear is fixed to a motor shaft of a motor 12 such as an induction motor or a synchronous motor suitable for driving an inverter. The electric motor 12 is fixed to the outer shell 2. Each motor 12 is driven by an inverter 13. Each inverter 13 is controlled by a control device 14. The outer shell 2 is provided with a laundry input port 15 communicating with the transfer opening 8 of the inner shell 1 of the tub S1.

As shown in FIGS. 2 to 5, the inner body 1 rotates counterclockwise in the order shown. The inner body 1 is provided with blades 19 that are inclined so that the phase is delayed as viewed in the normal rotation direction as the radius increases. The blades 19 are also inclined so as to be out of phase in the axial direction toward the transfer opening 8 in the forward rotation direction. Therefore, during the forward rotation, the laundry W is moved toward the outer peripheral side by the blades 19, and during the reverse rotation, it is moved toward the center side, so that the laundry is transported to the downstream side through the transport opening 8.

FIG. 6 shows a schematic flow of a standard cleaning. The laundry put in through the laundry inlet 15 is immersed in water in the tub S1, pre-washed in the tub S2, and washed in the tub S3.
4, the tanks S5 and 6 are sterilized by injecting live steam, the tanks S7 to S10 are rinsed, and the tanks S10 to S10 are rinsed.
Then, gluing is performed.

FIG. 7 shows a part of the inverter 13 and the control device 14. The control device 14 includes a shift register device 16
The shift register device 16 urges the relay R to switch its contacts R1-1 and R1-2 so that the contents of the shift register device 16 are sent to the normal rotation setting device r0 and the optimum rotation setting device r1. Has become. By turning on the contact R-1, for example, a normal rotation setting r provided with a potentiometer
0 is set. This normal rotation speed determines the reverse rotation speed of the inner body 1 in the case of transferring the laundry. By turning on the contact R-2, for example, an optimal rotation setting device r1 having a potentiometer
Operates to set a rotation speed suitable for the washing conditions in the shift register device 16, whereby the inverter 13 rotates the electric motor 12 respectively. Although not shown, the control device 14 controls a relay coil (not shown) that operates the contact R1-1 for rotating the motor 12 forward and the contact R2-1 for rotating the motor 12 reversely.

FIG. 8 is a timing chart showing the control of the relay coil R by the shift register device 16. The figure shows the transfer of the laundry, N-1 on the upstream side (N is the order number)
The portion in the tank and the Nth tank immediately downstream thereof are shown. Prior to time t1, both the Nth tank and the (N-1) th tank are rotating forward. At time t1, the Nth tank on the downstream side stops, and after a while, at time t2, the Nth tank reversely rotates. Then, at time t3, the N-1 tank on the upstream side stops, and at time t3
At 4, the reverse rotation of the Nth tank is stopped. At time t5, the (N-1) th tank rotates reversely, and at time t6, the (N-1) th tank stops reverse rotation. Also, the Nth tank stopped at about time t6 rotates forward, and the N-1th tank rotates forward at time t7. In the forward rotation at times t6 and t7, the Nth tank and the (N-1) th tank are shifted at the set speed by the shift register device 16 via the relay contact R-2 at the set speed of the Nth tank and the Nth tank via the relay contact R-2. The inner trunk 1 of the first tank rotates. At the time of reverse rotation, the contact R-1 is turned on, and the inverter 13 drives the electric motor 12 by the normal rotation speed setter r0, and reversely rotates the inner body 1 at a rotation speed suitable for transfer. Then, the reverse rotation in the (N-1) th tank is stopped, and the data of the shift register device 16 in the (N-1) th tank is sent to the shift register device 16 in the Nth tank. A signal for sending this data is such that a trigger pulse Trs is issued at the same time as the stop signal for the reverse rotation of the (N-1) th tank at time t6. The trigger pulse T sent to the shift register device 16
At rf, the contents of the shift register device 16 in the (N-1) th tank are erased.

In the shift register device 16, for example, the type and amount of detergent, the amount of bleach, sour, softer,
Temperature data is recorded in the form of a table, and the optimum rotation speed of each inner cylinder 1 for these combinations is determined.

In FIG. 1, it is assumed that the laundry is stored and washed in the inner trunk 1 of the first tub S1 to S10.
When the signal Trs to be transferred is output, the control device 14 controls the electric motor 12 via the inverter 13 to rotate the tub S10 in the reverse direction to discharge the laundry, stop the tub S10, and stop the tub S9 as described above. The laundry is transferred in the reverse direction from the tub S9 to the tub S10. In the same manner, the laundry is sequentially transferred from the N-1th tank to the Nth tank. Thus, when the laundry is transferred from the tub S1 to the tub S2, if the laundry that has not been sufficiently washed unless the laundry is washed at a rotation speed different from that of the laundry that has been washed until now comes from the laundry input port 15, the washing is performed. The type of laundry is input to the control device 14 using an input device (not shown). The controller 14 automatically selects the data in the shift register device 16 corresponding to the tub S1 and finds the optimum rotation speed in the tub S1 at the optimum rotation speed in the tub S1 for the corresponding laundry, and automatically sets the optimum rotation speed applicator r1. And the electric motor 12 is driven via the inverter 13 to rotate the inner body 1 forward at the optimum rotational speed. Next, when the laundry in the tubs S2 to S10 is sequentially fed and the tub S2 becomes empty, the tub S1 stops the reverse rotation as already described, and the trigger signal Trf generated at the same time causes
The optimum rotation speed setting device r1 is set so that the rotation speed becomes the optimum rotation speed of the tank S2, and the electric motor 12 rotates the inner body 1 of the tank S2 at the optimum rotation speed via the inverter 13. Similarly, the tubs S3 to S10 are sequentially rotated at an optimum rotation speed suitable for a new laundry to advance each washing process of the laundry. Tank S1
In the state where the different laundry that has been newly thrown in reaches 0,
The laundry is rotated at a rotational speed suitable for the laundry.
Is spinning and this continues. Next, when laundry requiring a rotation speed of the inner body 1 different from that of the laundry that has been flowing so far is newly introduced, the tubs S1 to S1 are similarly set.
The rotation speed of 0 sequentially becomes a rotation speed suitable for new laundry.

In the embodiment, the variable speed driving device is provided for all the inner cylinders. However, the variable speed driving device may be provided for some of the inner drums, and the remaining inner drums may be rotated at a constant rotation speed. .

[0018]

According to the present invention, there is provided a continuous washing machine having a multi-stage inner and outer drum and a driving device for driving a washing tub serving as an inner drum. The devices are distributed and connected to the multi-stage washing tub, respectively.
The drive for the partially continuous washing tub is a variable speed drive.
And variable speed drive is suitable for different laundry
Because was laundered is driven by the rotational speed choice controller continuous washing machine according to claim Rukoto, different kinds of laundry even when the laundered in succession, laundry respective inner e.g. terrible thing of soil The body is rotated at a high speed, and those with less dirt can rotate the inner body loosely, and those with easily damaged fabric can be rotated more slowly, so that the laundry can be washed at a rotation speed suitable for each laundry. In addition, since it is possible to successively input different laundry items requiring different washing times, in the case of laundry items that had to be washed at different rotation speeds as in the past,
It is much more efficient than a continuous washing machine that has been waiting for the same type of laundry to be washed once.
