In this embodiment, since the brush rod 20 is moved back and forth as described above, the rod inserting portion 1a formed in the water storage tank 1 is also formed wider by the movement interval, and is connected to the brush rod 20. Preferably, the water supply pipe 5 is further provided with a flexible portion 5a so as not to restrict the movement of the brush rod 20.

 In the case of the cleaning apparatus according to another embodiment of the present invention having the above-described configuration, the brush rod 20 is continuously provided without the need for the brush rod 20 to be mounted and only to be removed at the time of cleaning as in the above-described embodiment. The washing process and the cleaning process are performed in the state mounted on the rod holder 10, and the brush rod 20 has a difference in operation of separating the brush rod 20 only in the case of cleaning or replacing the brush rod 20 itself.

That is, when looking at the operation of the cleaning device according to another embodiment of the present invention in detail, first, as shown in Figure 7 even in the state of using a washing machine for everyday laundry purposes, unlike the above-described embodiment the brush rod 20 The water tank 1 and the washing tank (2) is in a state of being mounted.

Even when the brush rod 20 is mounted in this way, since the rod holder 10 is maintained in the reversed state as shown in FIG. 7, the washing brush 30 does not come into contact with the outer surface of the washing tub 2. It will remain spaced apart.

Therefore, the cleaning apparatus of the present embodiment does not have any influence on the rotational force of the washing tank 2, so that the laundry is washed in the same manner as a conventional washing machine without degrading the washing force.

When the washing tank 2 needs to be cleaned by repeating the washing process several times, the rod holder 10 is moved forward by operating the reciprocating driving unit 40.

When the rod holder 10 is moved forward, the brush rod 20 moves forward as shown in FIG. 9, and the washing brush 30 formed on the front side thereof is in contact with the outer surface of the washing tank 2. .

When the cleaning brush 30 is in contact with the outer surface of the washing tank 2, the same as in the above-described embodiment, the outer surface of the washing tank 2 is cleanly cleaned by friction of the washing brush 30 and the injection of water. The cleaning process is in progress.

Then, after the cleaning is completed, the reciprocating drive unit 40 is operated again to move the rod holder 10 back to the original position. Accordingly, the washing brush 30 is also repositioned while being spaced apart from the outer surface of the washing tank 2. As a result, the subsequent washing process can be performed in the same way.

On the other hand, if a lot of contaminants such as hair to the cleaning brush 30 by repeating the cleaning process as described above may reduce the cleaning efficiency, in this case, after separating the brush rod 20 and cleaning it separately It may be used by mounting, if the cleaning brush 30 is damaged due to frequent cleaning it will be used to replace with a new brush rod (20).

As described above, the embodiment of the present invention, the cleaning device of the present invention, the user can easily wash the tank directly through the friction action of the washing brush and the spraying action of water without having to use a chemical cleaning agent or to request a client, etc. It can be seen that it can be cleaned cleanly, and at the same time, since the washing brush is selectively in contact with the washing tank only when cleaning, it can be seen that the general washing does not affect the rotational force of the washing tank at all.
