Abstract
The invention relates to a cleaning device for a piping system of a whirlpool tub where one or more outlet valves supply water and/or air into the interior of the tub. The outlet valves branch off from a cleaning-fluid circulation system using a delivery pump to circulate the cleaning fluid. When the cleaning fluid is circulated the outlet valves are in a closed position, receiving a flow of the cleaning fluid, but preventing the issuance of the cleaning fluid into the tub interior. The outlet valve has a water-supply line connecting into a water-distribution chamber disposed in a valve body, from which a water-outlet channel branches toward the tub interior. The water-outlet channel guides, in a watertight and axially movable manner, a sealing member passing through the water-distribution chamber. The sealing member has a smaller cross section than the water-distribution chamber, and an end face of the sealing remember, when in a closed position, is precisely flush with or bulges just slightly beyond an adjoining end face of the valve body.
