The outer shell 1 is fixed, and the inner shell 2 can swing and rotate about a horizontal axis. The inside of the outer shell 1 is partitioned into a plurality of washing rooms 4a... 4f by a donut-shaped disk 3 having a round opening 5 at the center. The inner body 2 has a structure in which short cylindrical washing tubs 2a... 2f provided in the respective washing rooms 4a... 4f are integrally connected by a short pipe-shaped passage penetrating the opening 5 of the partition wall. At both ends, there are provided an inlet 6 for charging laundry and an outlet 7 for discharging washed laundry. Chutes 8 and 9 for guiding the laundry corresponding to the laundry inlet 6 and the outlet 7 of the inner trunk are provided at the small end of the outer trunk 1.
[0003]
The inner body 2 is rotatably and rotatably supported on the outer body 1 by a bearing (not shown) around the axis, and an electric motor (not shown) that swings and rotates one turn at a predetermined timing is provided. ing.
[0004]
Each of the inner tubs 2a to 2f is provided with a scoop 10 shaped like a conch shell connected to an opening connecting the adjacent tubs. The inner body 2 performs washing by swinging with the scoop 10 facing upward. Washing water and detergent liquid are supplied to each laundry room through a water supply pipe, a drain pipe, a steam pipe, a detergent supply pipe, and the like attached to the peripheral wall of the outer shell.
[0005]
The laundry room formed by dividing into a plurality of compartments is set from the laundry input port 6 side to, for example, two spare laundry rooms, two main laundry rooms, and two rinsing rooms, and accordingly, Detergent and fresh water are supplied. The laundry put into the inner body 2 is agitated in the washing water in each washing room by the swinging of the inner body, and the washing is performed. By rotating the inner body 2 one time at a time, the laundry is scooped up by the scoop 10, and the laundry is slid along the surface of the scoop inclined in a spiral conical shape, to the laundry tub adjacent to the discharge port 7 side. Transfer the laundry at the same time.
[0006]
In the conventional continuous washing machine having the above structure, a large number of punch holes 11 are provided on the entire circumference of the inner shell 2 so that washing water can freely flow between the outer shell and the outer shell. This conventional structure is basically intended to transfer only the laundry to the adjacent washing tub while leaving the washing water in each laundry room as it is, but in reality, the laundry has a large amount of water. Is contained, and a considerable amount of water flows with the laundry, so that the washing water of several times the dry weight of the laundry is transferred to the adjacent laundry room together with the laundry. Therefore, in this type of continuous flushing device, an operation is performed in which the flow of the wash water in the direction opposite to the transfer direction of the laundry is generated in the pipe provided on the outer body, and the wash water transported with the laundry is sent back. .
[0007]
[Problems to be solved by the invention]
As described above, the continuous washing machine continuously performs the washing while sequentially transferring the laundry from the input port 6 to the discharge port 7 into the plurality of washing tubs, and thus the linen for business use such as sheets and towels. Suitable for washing products in large quantities. As described above, in the continuous washing machine, since the washing water moves between the washing rooms, it is relatively difficult to maintain the detergent concentration and the temperature of the washing water in each washing room at desired values. However, linen products for business use are relatively free of dirt, so that no trouble was caused by washing with a conventional continuous washing machine.
[0008]
However, since a continuous washing machine can continuously process a large amount of laundry without human intervention, there is a demand for washing a highly soiled laundry with a continuous washing machine. The number of cases of washing with a continuous washing machine is increasing. However, in such a case, the conventional washing machine having a conventional structure has a problem that the washing power is insufficient and dirt remains.
[0009]
SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problem, and has as its object to provide a continuous washing machine capable of preventing washing liquid from being diluted by a flow and enabling washing of strongly soiled laundry.
[0010]
[Means for Solving the Problems]
The continuous washing machine of the present invention has a plurality of washing rooms 4a... 4f formed by partitioning the inside of an outer shell 1 with a partition wall 3 having an opening at the center, and a short cylindrical shape provided in each washing room. The washing tubs 2a... 2f are integrally connected by a short passage passing through the opening, and the laundry in each washing tub is scooped up and transferred to an adjacent washing tub when the inner trunk 2 makes one rotation. in a continuous washing machine comprising a scoop 10, the communication holes 11 for circulating the washing water between the tub 2a · · · 2f and laundry 4a · · · 4f scoop 10 of non-permeable for the washing tub The above-mentioned problem is solved by providing only the rear side portion. That is, a plurality of washing tubs (not necessarily all the washing tubs) provided on the inner body of the continuous washing machine of the present invention include a scoop formed of a water-impermeable plate material and a portion behind the scoop. It is provided with a water-permeable partition located therein and a non-water-permeable partition other than the part behind the partition.
[0011]
In the washing method using the continuous washing machine of the present invention, when the washing is continued without converting the washing water, the washing water circulation hole 11 reciprocates the inner body 2 within an angle range in which the washing water circulation hole 11 does not reach the washing water surface. When the water is swung to convert the washing water in the washing tub, the inner body 2 is swung to an angle at which the flow hole 11 of the washing water is positioned below the water level of the washing water.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
1 to 4 are schematic views showing one embodiment of the continuous water washer of the present invention and the operation thereof. The entire structure of the continuous washing machine of the present invention is the same as that of the conventional structure shown in FIG. The difference between the continuous washing machine of the present invention and the continuous washing machine of the conventional structure is that the washing water circulation hole (punch hole) 11 provided conventionally on the entire circumference of the inner body is replaced with the washing water flowing hole (punch hole) behind the scoop in the present invention. This is a point provided only in part. In the embodiment shown in FIG. 1, a large number of punch holes 11 provided on the outer peripheral surface of the inner body 2 form washing water circulation holes, and the punch holes 11 are provided only in a portion behind the scoop 10. I have. In addition, the scoop 10 is also formed of a metal plate that does not allow water to pass through (has no punch holes).
[0013]
The inner body 2 thus formed is swingably and rotatably mounted at a small distance from the inner wall surface of the outer body 1 in the same manner as that of the conventional structure, and the inner body 2 is swung by the swinging operation. Wash the items by stirring them in the washing water. The inner trunk shown in the figure is provided with three breakers 12 for effectively transmitting the movement of the inner trunk to the laundry.
[0014]
2 and 3 show a state in which washing without conversion of washing water is performed. FIG. 2 shows a position of the left swing end of the inner body 2, and FIG. 3 shows a position of the right swing end. is there. In the washing without the conversion of the washing water, the inner body 2 is swung within an angle range in which the area 13 provided with the punch holes of the inner body does not sink into the washing water. In this swing range, the washing water in the inner body 2 is in a state of being sealed in the inner body 2. In this state, when the inner drum 2 is rotated clockwise in the figure, the laundry put in each washing tub of the inner drum is transferred to the adjacent washing tub together with the washing water in the washing tub.
[0015]
That is, in the continuous washing machine according to the present invention, the inner body is swung within a range in which washing water does not flow between the outer body and the outer body, and the inner body is rotated once to transfer the laundry. Sometimes, the washing water is transferred together with the laundry, so that the phenomenon that the washing water is diluted does not occur, and the desired detergent concentration can be maintained. Therefore, by performing washing in this manner, it is possible to more completely wash laundry that is very dirty.
[0016]
When the washing water in the inner body is converted, as shown in FIG. 4, the inner body 2 is swung to an angle at which the portion 13 provided with the punch holes of the inner body enters the washing water. In this state, since the inside of the inner body 2 communicates with the inside of the outer body 1, the drain pipe 15 communicating with the drain port 14 opened on the bottom surface of the outer body 2 is opened to exchange the washing water. The washing water in the washing tub is discharged, and water and necessary detergent liquid are supplied from a water supply pipe and a detergent liquid supply pipe (not shown) communicating with the outer shell to convert the washing water. In a washing tub that does not convert washing water, a drain pipe or a water supply pipe communicating with the outer shell of that portion may be kept closed.
[0017]
If the gap between the inner shell 2 and the outer shell 1 is narrowed, the dilution or fluctuation of the washing water due to the communication between the outer shell and the inner shell is small. The temperature of the washing water in the inner shell can be controlled by supplying steam to the outer shell, and there is no need to communicate the inner shell with the outer shell.
[0018]
As described above, in the continuous washing machine of the present invention, the washing water can be transferred together with the laundry, and the washing liquid can be converted into the required washing tub at the required timing. Accurate washing according to dirt becomes possible. Further, in the continuous washing machine according to the present invention, the washing water can be moved together with the laundry, and the unintended flow of the washing water hardly occurs. The danger of coloring objects can be almost completely avoided.
