Since the drum 1 rotates, a lip seal 11 is attached for sealing the drain boxes 2 and 5 and the heating boxes 3 and 4. Usually, the lip seal 11 is fixed to the fixed sides of the drain boxes 2 and 5 and the heating boxes 3 and 4 with bolts (not shown). By using elastic rubber as the material of the lip seal 11, the leakage of the cleaning liquid 9 is prevented by the structure in which the elastic force of this rubber slides on the sealing surface of the drum 1.

Reference numeral 15 shown in FIG. 4 denotes an immersion water tank. When the object to be washed 10 is supplied into the drum 1, the immersion water is simultaneously supplied from the tank 15 to wet the object to be washed 40 in a short time. Makes it easier to remove dirt. Reference numeral 16 is a recycle tank, and rinse water 20 is supplied into the drum via a rotary joint 18. After rinsing the object to be washed 10, this rinse water 20 overflows from the height-adjustable water level adjusting pipe 21 attached to the drain box 5, and is stored in the recycle tank 16. At this time, the water level in the rinsing zone Z in the rotary drum 1 is kept constant by the water level adjusting pipe 21. Reference numeral 17 denotes a water recovery tank. This tank 17 is for recovering and storing the cleaning liquid 9 discharged from the rotating drum 1 together with the washed object 10 to be washed from a subsequent dehydrator or the like (not shown).

At this time, a certain amount of the cleaning liquid 9 is soaked from the recycle tank 16 by the pump 161 and is supplied to the water tank 15, and these mixed liquids are soaked and used as water.

Reference numeral 22 denotes a main washing water supply pipe, and a fixed amount of the cleaning liquid 9 is usually supplied from the recycle tank 16 to the heating tank 4 by the pump 162 via the main supply pipe 22. At this time, the valve 24 fixed to the height-adjustable water level adjusting pipe 23 attached to the heating tank 4 is in a closed state (FIG. 7). The cleaning liquid 9 supplied here flows in the direction opposite to that of the object to be cleaned 10 and is discharged to the outside of the drum 1 through the water level adjusting pipe 26 of the drain box 2 whose height can be adjusted. Normally, the valve 28 is open, and the cleaning liquid 9 supplied to the heating box 4 can be discharged. Reference numeral 25 denotes a drain water discharge pipe, which is fixed to the drain box 2 and discharges dirt deposited on the bottom surface of the drain box 2 by operating the air cylinder 27. The air cylinder 27 has a structure in which it is closed for a certain period of time by a timer (not shown) and then closed (FIG. 6). Reference numeral 31 is a cleaning liquid supply pipe, which is a supply pipe for supplying a cleaning solution from the drain box 2, and is normally supplied from the recovery tank 17 or a hot water tank (not shown) by a pump (not shown) in a fixed amount. Reference numeral 35 denotes a recycle tank drain valve that allows the water in the recycle tank 16 to be drained when the object to be washed 10 that easily discolors is treated. Reference numeral 36 denotes a fresh water supply pipe for main washing, which is a water source when the water in the recycle tank 16 cannot be used. The temperature of the wash water (discharged water) having the above-described structure is as shown in FIG.

[0005]

[Problems to be solved by the device]

 The objects to be washed transferred from the main washing zone to the rinsing zone are sent together with high temperature water. Initially, this high-temperature wastewater is subsequently fed to the recycling tank as lower-temperature rinse wastewater. By the way, it is not suitable to supply only the rinse drainage from the recycling tank to the prewash zone because it is necessary to keep the temperature below 35 ° C to prevent protein dirt from coagulating as the prewash water. .. Therefore, this high-temperature water must be mixed with the water recovered from the dehydrator, etc., and the temperature must be lowered before it is supplied to the prewash zone. On the contrary, since the rinse drainage water in the recycle tank for the main wash zone is at a low temperature for the main wash zone, it is necessary to raise the temperature in the heating box, resulting in poor efficiency. That is, as described above, there is a disadvantage that the drainage temperature of the recycling tank does not match the temperature of the destination. Therefore, the present invention provides a continuous water washing apparatus that eliminates the disadvantage of such drainage.

[0006]

[Means for Solving the Problems]

 For this reason, the present invention has a drum having an inlet and an outlet for the item to be washed, and separating the drum into each tank, and sequentially transferring the items from the inlet to the outlet, prewash zone, main wash zone, rinse zone. In a continuous water washing machine that performs continuous washing and rinsing of items, two or more tanks that collect wastewater from the rinsing tank and drainage water from the rinsing tank to each tank via a switching valve. The drainage connection pipe and the switching valve are switched to control each tank to store wastewater of different temperature, and the wastewater stored in each tank is supplied to the main wash zone and the prewash zone. And a means for doing so, which is a means for solving the problem.

[0007]

[Action]

 The drainage water from the drain box 5 is supplied to two or more tanks, for example, the recycling tanks 16a or 16b, via a switching valve controlled by a temperature detector of the wastewater by a controller or a timer. That is, when the temperature is equal to or higher than a preset temperature, it is supplied to the recycle tank 16a, and when it is lower than the preset temperature, it is supplied to the recycle tank 16b, and the waste water having different temperatures is stored in the tanks 16a and 16b. Further, since the timing at which the item to be washed is sent to the next tank is known, the switching valve may be switched by a timer from that time, and the recycle tanks 16a and 16b may be stored so as to have different temperatures. With the wastewater from the recycling tanks having different temperatures, high-temperature wastewater is supplied to the main wash zone and low-temperature wastewater is supplied to the prewash zone.
