By the way, in this continuous washing machine, in order to control the rotation of the drum 1 and the operation of the conveyor 180 for putting the article 10 into the drum 1, an operation control device 200 is provided. The operation control apparatus 200 controls the operation of the drum 1 and the conveyor 180 according to the time schedule set by the setting device 201.
[0035]
That is, the setting device 201 can input and set the scheduled start time and the scheduled end time of the washing process by the continuous water washer. If attention is paid to the function of setting the scheduled end time among the functions of the setting device 201, the setting device 201 functions as an end setting means.
The operation control device 200 controls the operation of the drum 1 and the conveyor 180 based on the start time and end time set by the setting device 201 and the time information obtained from the timer 202. Based on the set end time, the following processing is performed.

Is stopped, the stoppage of the object to be washed 10 is instructed to be stopped into the drum 1, and then the area in which the object to be cleaned 10 is empty is not present in the drum 1 due to the stoppage of the object to be cleaned 10. As the vehicle advances, the operation of the drum 1 is instructed to stop when the inside of the rinsing zone Z becomes empty.
[0037]
Note that the function of commanding the operation stop of the object to be washed 10 in the operation control device 200 is referred to as the object to be washed input canceling means 200A, and the function of instructing to stop the operation of the drum 1 is referred to as the operation stopping means 200B.
By the way, the charging stop of the article to be cleaned 10 is performed for a predetermined time. This predetermined time is a time required for the article to be cleaned 10 to pass through the rinsing zone Z. In addition, the start of the charging stop is a time set in advance before the scheduled end time, and this set time is the same as that of the entire zone of the drum 1 [that is, the first (No. 1) ) Is the time required to pass the 14th (No. 14)] tank.
[0038]
The time required for the article to be washed 10 to pass through the rinsing zone Z corresponds to the number of tanks in the rinsing zone Z, and it is necessary for the article to be washed 10 to pass through all the zones of the drum 1. The time corresponds to the total number of tanks in the drum 1.
In other words, the object to be cleaned 10 is subjected to the scouring or scouring rinse (swinging) by forward / reverse rotation of the drum 1 a predetermined number of times (accordingly, for a certain period of time). Therefore, it is transferred to the next tank by the principle of screw. Therefore, it takes a certain amount of time (transfer) to be transferred from one tank to the next tank.SendingCycle) T₁ Will be required.
[0039]
When the article to be washed 10 enters the rinsing zone Z, the rinsing zone Z has No. 10-No. Since there are five tanks up to 14, the time required for the article to be washed 10 to pass through the rinsing zone Z is 5 cycles, that is, 5T.₁It becomes. In the drum 1, no. 1-No. Since there are 14 tanks up to 14, the time required to pass through all zones of the drum 1 is 14 cycles, ie 14T₁It becomes.
[0040]
Therefore, in the operation control apparatus 200, the time 14T is set with respect to the scheduled end time T.₁Only before (ie, time T-14T₁To 5T₁Time only (ie, time T-9T₁The operation of the conveyor 180 is stopped, the charging of the article 10 to be washed into the drum 1 is stopped, and thereafter (that is, time T-9T).₁From the start of the operation of the conveyor 180 again, the charging of the article to be washed 10 is started, and when the scheduled end time T is reached, both the operation of the conveyor 180 and the drum 1 are stopped.
[0041]
Since the embodiment of the present invention is configured as described above, the washing process is performed in the following procedure by the control through the operation control device 200.
That is, when performing a normal washing process, the conveyor 180 and the drum 1 are operated as shown in FIG. A constant amount of water is supplied from the immersion water tank 15 in accordance with the weight of the object to be cleaned, while the object to be cleaned 10 is rotated in the drum 1 by a predetermined number of forward and reverse rotations. A certain number of scouring washing processes are performed through a beater (not shown), and then the drum 1 is rotated once so that the object to be washed 10 is transferred to the next tank by the screw principle. Thereafter, in each tank, a washing process (pre-washing and main washing) and a rinsing process by a predetermined number of forward / reverse rotations are sequentially performed and sent to the dehydrator 181 in the next process.
[0042]
During this time, the object to be washed 10 is washed with water in the pre-wash zone X, in the main wash zone Y, with main wash water containing detergent, and in the rinse zone Z with a chlorine-based chemical (for example, sodium hypochlorite). It is rinsed with the rinse water that has entered, bleached and sterilized, and sent to the dehydrator 181 from the outlet 1B.
That is, at the end of the washing process, first, the operation control apparatus 200 has a time 14T required to pass through all zones of the drum 1 with respect to the scheduled end time T.₁Only before (ie, time T-14T₁), The time required for the article 10 to pass through the rinsing zone Z is 5T.₁Only (ie, time T-9T₁Until the operation of the conveyor 180 is stopped, the charging of the article to be cleaned 10 into the drum 1 is stopped (first step).
[0043]
As a result, an empty area without the object to be cleaned 10 is generated in the drum 1, and this area is moved.SendingHowever, as shown in FIG.
After this (ie, time T-9T₁ )) Again, the operation of the conveyor 180OpenIt starts and starts the injection | throwing-in of the to-be-washed object 10 (2nd step). When the scheduled end time T is reached, both the conveyor 180 and the drum 1 are stopped (third step).
[0044]
As a result, as shown in FIG. 1C, each tank in the rinsing zone Z becomes an empty area without the object to be cleaned 10. Here, the valve 52 is opened, and the rinse water in the rinse zone Z is discharged through the drain box 5 and the quick drain pipe 51.
At the start of work on the next day, after supplying rinsing water into each tank of the rinsing zone Z, the washing object 10 may be started and the regular washing process may be started.
[0045]
As a result, for example, until the time when the operation is resumed the next day, the rinsing zone Z is empty without the rinsing water 10 and the rinsing water containing the chlorinated chemical, and the continuous washing machine is suspended (from the end of the washing process). The washing object 10 is not immersed in the rinse water containing chlorine-based chemicals for bleaching and sterilization in the rinsing zone Z until the washing process is resumed the next day). In addition, the possibility of corrosion occurring in each tank of the rinsing zone Z can be eliminated.
[0046]
Of course, in the pre-washing zone X and the main washing zone Y other than the rinsing zone Z, the objects to be washed 10 and the washing liquid in the drum 1 are not emptied, so that these washing zones X and Y are emptied. There is no need for time or time for filling the objects to be cleaned 10 or the cleaning liquid in the empty washing zones X and Y at the start of work, and the advantage that the work efficiency can be improved, and the cleaning liquid, detergent or heating Efficient use of steamuseThere are advantages that you will be able to.
[0047]
In addition, the above-described discharge of rinse water at the end of work and the supply of rinse water at the start of work, as well as various supply and discharge processes for liquids, detergents, chemicals, etc. related to the washing process are performed automatically. May be.
In addition, the present washing method is not limited to automatic washing through the operation control device 200 as in the present embodiment, and may be performed manually.
[0048]
Further, if at least the tank in the rinsing zone Z of the drum 1 has sufficient durability against chlorine-based chemicals and the like, discharging of rinsing water at the end of the washing operation may be omitted.
Furthermore, in this apparatus and this method, it sets so that only each tank in the rinse zone Z may become an empty area | region without the to-be-washed object 10, as shown in FIG. From the viewpoint of efficient use of work efficiency, cleaning liquid, detergent, heating steam, etc., such a setting is most preferable, but at the end of the washing work, at least for each tank in the rinse zone Z The other tanks may be empty areas.
[0049]
That is, the stoppage of charging of the article 10 into the drum 1 is a time 14T required to pass through all zones of the drum 1 with respect to the scheduled end time T.₁Above (ie, time T-14T)₁5T before the washing object 10 passes through the rinsing zone Z₁Longer than (ie, time T-9T₁Or later).
[0050]
【The invention's effect】
As described in detail above, according to the washing method using the continuous water washer according to claim 1 and the continuous water washer according to claim 2, the washing process is completed at an appropriate timing. Since the introduction of the washing object is stopped, the washing zone becomes empty without the washing object at the end of the washing process, and even if the medicine is put in the rinsing zone, the next washing The washing object is damaged by the medicine in the rinse zone until the start of the treatment.situationIs avoidedAt the same time, since the rinsing liquid in the drum in the rinsing zone is emptied and the operation is completed, the occurrence of corrosion of the drum can be prevented.In addition, in the laundry zones other than the rinse zone, the items to be washed remain until the next washing process starts.ThingsThe time for emptying and the time for filling the objects to be washed and the cleaning liquid in the empty laundry zone at the start of work is not required, so that the work efficiency can be improved and the cleaning liquid, detergent, steam for heating, etc. Efficient useKiBecome so.
