Abstract: A washing method of a water treatment apparatus is provided. The washing method includes a wash water inflow operation in which wash water flows into circulation members, and a circulation washing operation in which a circulation modulation circulates the wash water through passages of the water treatment apparatus.

Abstract: A washing device for a water treatment apparatus is provided. The washing device includes circulation members connected to passages of the water treatment apparatus to circulate wash water through the passages of the water treatment apparatus, a circulation module connected to the circulation members for circulating the wash water through the passages of the water treatment apparatus, with the circulation members thereby washing the passages of the water treatment apparatus, a drainpipe connected to the circulation members, a passage switching unit connected to a portion where the circulation members are coupled to the drainpipe to switch passage of the wash water, and a circulation pump connected to the circulation members to selectively circulate the wash water in the connection pipes through the drainpipe or the passages of the water treatment apparatus.

Abstract: A washing device for a water treatment apparatus is provided. The washing device includes circulation members and a circulation module. The circulation members are connected to passages of the water treatment apparatus to circulate wash water through the passages of the water treatment apparatus. The circulation module is connected to the circulation members for circulating the wash water through the passages of the water treatment apparatus, with the circulation members thereby washing the passages of the water treatment apparatus.

Abstract: The present invention relates to a washing device for a water treatment apparatus and a washing method thereof that can wash hard to reach areas with hands inside the water treatment apparatus. A washing device for a water treatment apparatus according to an aspect of the invention may include: circulation members connected to passages of the water treatment apparatus to circulate wash water through the passages of the water treatment apparatus; and a circulation module connected to the circulation members and circulating the wash water through the passages of the water treatment apparatus and the circulation members to thereby wash the passages of the water treatment apparatus.
