Kind Code:
B2
Abstract:
To provide a bathtub washing device capable of efficiently spraying detergent waster in a limited amount to an entire inside wall surface of a bathtub, and capable of suppressing an occurrence of a part on the inside wall surface of the bathtub to which detergent waster does not adhere.SOLUTION: A bathtub washing device includes: a tank for storing detergent; a detergent mixing part for generating detergent water; a nozzle provided on an inner bottom surface of a bathtub for jetting the detergent water toward a part of an inside wall surface of the bathtub; a jetting control part for controlling the jetting of the detergent water; a rotation part for rotating the nozzle with a vertical direction as an axis; and a control part. The inside wall surface includes a first region whose distance in a horizontal direction to the nozzle is less than a predetermined distance, and a second region whose distance in a horizontal direction to the nozzle is equal to or longer than the predetermined distance. The control part controls the jetting control part and the rotation part so that the nozzle is rotated a plurality of times, and a jetting amount in a predetermined angular range in jetting the detergent water toward the second region becomes larger than a jetting amount in the predetermined angular range in jetting the detergent water toward the first region.SELECTED DRAWING: Figure 6
