[Detailed Description of the Invention] The present invention relates to a continuous washing machine that continuously washes clothes and other items to be washed.

Generally, a conventional continuous water washer used in the linen industry is constructed as shown in FIGS. 1 and 2. In the figure, reference numeral 1 denotes a cylindrical rotating tank 1 which is rotated in a predetermined direction by a drive device (not shown) to wash the items 2 to be washed. An article inlet 3 for washing is provided at one end of the rotary tank 1, and the articles 2 to be washed are introduced into the rotary bath 1 through the inlet 3. Further, a partition plate 4 is provided on the inner wall of the rotating tank 1. This partition plate 4 is provided continuously in a spiral shape along the inner wall of the rotating tank 1 so that the items 2 to be washed, which are inputted from the item input port 3, are moved in the direction of arrow A by the rotation of the rotating tank 1. ing. The partition plate 4 is provided with a large number of wash water holes 5, and the wash water 6 in the rotating tank 1 passes through the wash water holes 5 in a direction opposite to the object 2 to be washed. It's starting to flow.

Further, a fixed tank 7 is provided on the outer periphery of the rotating tank 1 to keep the water level in the rotating tank 1 constant. That is, a height-adjustable water level adjustment pipe 8 is provided in the fixed tank 7, and the water level adjustment pipe 8 discharges overflowing wash water to the outside of the machine to maintain a constant water level in the rotating tank 1. I'm learning to keep it that way. A large number of cleaning water inflow holes 9 are provided on the outer peripheral surface of the rotating tank 1 covered with the fixed tank 7, and the cleaning water in the rotating tank 1 flows into the fixed tank 7 through these inflow holes 9. There is an influx. Further, the gap between the rotating tank 1 and the fixed tank 7 is sealed by a sliding annular packing 10.

In the above configuration, the object to be washed 2 inputted from the object to be washed input port 3 advances in the direction of arrow A as the rotating tank 1 rotates, and is washed by the washing water 6 supplied from the opposite direction. Ru. On the other hand, the sludge separated from the object 2 by the washing water 6 flows into the fixed tank 7 from the washing water inlet 9, and the floating matter and floating dirt among the sludge are adjusted in water level along with the overflowing washing water 6. It is discharged from the machine through pipe 8.

By the way, in such a conventional continuous water washer, among the sludge separated from the object 2 to be washed, floating objects and floating dirt can be relatively easily discharged out of the machine through the water level control pipe 8, but sediments and There is a problem in that dirt and the like accumulate at the bottom of the fixing tank 7 and are difficult to discharge, and this sometimes causes back contamination.

The present invention was made to solve the above problems, and its purpose is to provide a continuous water washer that prevents the occurrence of back contamination and has an extremely high cleaning effect on the items being washed. .

In order to achieve the above object, the present invention includes a cylindrical rotating tank having an input port at one end, and a spirally arranged inner surface of the rotating tank, and the articles to be washed that are input from the input port into the rotating tank. a partition plate that conveys washing water in the direction opposite to the direction of the washing water flowing in the rotating tank toward the input port by the rotation of the rotating tank, and a partition plate that is provided on the outer periphery of at least both ends of the rotating tank and allows the rotating tank to freely rotate through a sealing member. a fixed tank supported by the rotary tank; an inflow hole formed on the outer circumferential surface of the rotary tank through which the sludge separated from the object to be washed flows into the fixed tank; A water level control pipe for discharging floating matter to the outside together with overflow water, and a sediment discharge device provided at the bottom of the fixed tank for discharging to the outside sediments among the sludge that has flowed into the fixed tank from the inflow hole. , and a water supply device connected to the fixed tank via a water supply pipe.

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 3 and 4.

FIG. 3 is a cross-sectional view of a continuous water washer showing an embodiment of the present invention. In the figure, the same parts as in FIG. In this embodiment, as shown in the figure, a sediment discharge port 11 is provided at the bottom of the fixed tank 7, and an automatic valve 12 as a sediment discharge device is attached to this sediment discharge port 11. This automatic valve 12 is housed in a box body 13 connected to a sediment discharge pipe 14, and is driven by a drive mechanism 15. Further, above the fixed tank 7, a water tank (water supply device) 16 is installed which stores water or hot water. This water tank 16 is connected to the intermediate portion of the fixed tank 7 via a water supply pipe 17, and is adapted to supply water or hot water to the fixed tank 7. An automatic valve 19 is attached to the water supply port 18 of this water tank 16, and this automatic valve 19 is connected to the drive mechanism 2.
0.

Next, the operation of this embodiment with the above configuration will be explained. As mentioned above, the object to be washed 2 inputted from the object to be washed input port 3 advances in the direction of arrow A as the rotary tank 1 rotates, and is washed by the washing water 6 supplied from the opposite direction. . On the other hand, the sludge separated from the object 2 by the washing water 6 flows into the fixed tank 7 from the washing water inlet 9, and floating matter and floating dirt among the sludge are raised to the water level along with the overflowing washing water 6. It is discharged from the control pipe 8 to the outside of the machine. In addition, sludge, which has a specific gravity heavier than water, becomes sediment and accumulates at the bottom of the fixed tank 7, but in this embodiment, the automatic valve 12 is opened for a certain period of time in accordance with the operating cycle, so that the sludge accumulates at the bottom of the fixed tank 7. The collected precipitate is discharged from the precipitate discharge port 11 to the outside of the machine together with the washing water 6 via the precipitate discharge pipe 14. Also, at this time, the water level in the rotating tank 1 temporarily decreases, but after closing the automatic valve 12, the automatic valve 19 of the water tank 16 is opened, so that the water in the water tank 16 is drained through the water supply pipe 17. Since the water is supplied to the fixed tank 7, the water level in the rotating tank 1 is restored to its original level.

As described above, according to this embodiment, in addition to the water level control pipe 8, the automatic valve 12 as a sediment discharge device is provided at the bottom of the fixed tank 7, so that all floating matter and sediment that have flowed into the fixed tank 7 can be removed. Since it can be discharged outside the machine, back contamination can be prevented. Furthermore, according to this embodiment, the water level that has fallen due to the discharge of sediment can be recovered in a short time by supplying water from the water tank 16, so that the cleaning effect on the object 2 to be washed can be achieved in approximately the same cleaning time as in the conventional method. can be increased.

In the above embodiment, the automatic valve 12 was used as the sediment discharge device, but according to the present invention, the same effect can be obtained even if a pump 31 is used instead of the automatic valve 12, as shown in FIG. . Also,
As shown in the figure, the water in the water tank 16 may be supplied to the fixed tank 7 by a pump 32.

As is clear from the above description, according to the present invention, there is provided a cylindrical rotating tank having an input port at one end, a spirally formed inner surface of the rotating tank, and the articles to be washed that are inputted from the input port into the rotating tank. A partition plate is provided on the outer periphery of at least both ends of the rotary tank to transport the washing water in the opposite direction to the direction of the input port in the rotary tank due to the rotation of the rotary tank, and a partition plate is provided on the outer periphery of at least both ends of the rotary tank to connect the rotary tank to the input port through a sealing member. a fixed tank supported rotatably; an inflow hole formed on the outer circumferential surface of the rotating tank through which sludge separated from the object to be washed flows into the fixed tank; and sludge that flows into the fixed tank from the inflow hole. A water level control pipe for discharging floating matter to the outside along with overflow water, and a sediment discharge pipe for discharging to the outside the sediments of the sludge that have flowed into the fixed tank from the inlet hole provided at the bottom of the fixed tank. and a water supply device connected to the fixed tank via a water supply pipe. Therefore, among the sludge that has flowed into the fixed tank from the inflow hole, suspended matter is discharged to the outside from the water level control pipe, and sediment is discharged from the sediment discharge device, so that the sludge that has flowed into the fixed tank is It is possible to prevent back contamination caused by washing and improve the cleaning effect of the items to be washed. In addition, since the fixed tank is connected to a water supply device via a water supply pipe, water can be replenished into the fixed tank from the water supply device, and the drop in the water level in the fixed tank caused by the sediment discharge device can be avoided in a short time. can be recovered.
