Definitions

  • the invention relates to a whirlpool tub with a drainage device and a pipe system equipped with a circulating pump for supplying at least one nozzle opening into the tub interior with water and / or air a connection chamber is in flow connection, a discharge nozzle equipped with a discharge valve and opening into the discharge line protruding into the connection chamber and the connection valve being effective between the discharge nozzle and the connection chamber wall.
  • connection valve effective between the drain connection and the connection chamber wall consists, for example, of an elastic membrane fixed on the discharge connection, for example made of rubber, which in the closed position rests with its outer edge on the connection chamber wall or a part thereof for the purpose of sealing and is exposed to excess pressure or negative pressure in the piping system or in the connection chamber opposite the inside of the tub either to the inside of the tub bends towards or away from the interior of the tub and thereby more or less releases the flow cross-section of the connection valve.
  • the sealing effect of such a connection valve which has an unfavorable flow resistance, is relatively low. At high flow velocities, undefined flow conditions arise.
  • the object of the present invention is to provide a whirlpool bath of the generic type with better functionality while avoiding the aforementioned disadvantages.
  • connection valve has a valve body which is guided on the drain connection and is pressed under the action of a closing spring in the direction of its sealing seat, and that the sealing seat narrows conically in the closing direction Valve seat surfaces of the drain connector and the connection chamber wall is formed.
  • the valve body of the connection valve always assumes a defined closing or opening position in accordance with the respective pressure conditions.
  • connection valve When the circulation pump in the pipeline system is actuated, that is to say when the whirl pool nozzle is in operation, the negative pressure which occurs in the connection chamber ensures that the valve body of the connection valve is lifted from the conical valve seat surfaces between the discharge nozzle and Connection chamber wall. Due to the flow pressure, the valve body of the connecting valve is kept open against the action of the closing spring. When the circulation pump is switched off, the connection valve is immediately reliably closed again under the action of the closing spring. A negative pressure above the connection valve increases the closing force due to the conically tapering valve seat surfaces of the connection valve.
  • connection chamber By protruding the drain connector into the connection chamber up to the drain opening in the tub floor, the entire area of the connection chamber remains filled with cleaning liquid during the period between two uses of the whirlpool tub, so that no sustainable dirt can be deposited in the entire area below the connection valve.
  • the closing spring force acting in the closing direction of the connecting valve is only slightly greater than the sum of all forces acting in the opening direction on the valve body of the connecting valve in the closing position of the connecting valve. In this way, a relatively low vacuum in the piping system is sufficient to open the connection valve. This can be achieved, for example, by switching on the circulation pump in a pulsed manner, as a result of which the initial static and sliding friction forces are overcome.
  • valve body of the connection valve coaxially surrounds the drain connection, so that it receives particularly good guidance on the drain connection, for which purpose the latter can have, for example, a special guide section on its circumference along which a sleeve-like extension of the valve body slides.
  • the closing spring is accommodated in a recess between the drain socket and the valve body of the connection valve.
  • the closing spring which can be supported on opposing shoulders of the drain connector and the valve body of the connection valve, securely maintains its position. It is also protected inside the valve body.
  • valve body of the connection valve has at its upper end a snap-on sealing ring with annular sealing lips projecting radially outward and radially inward, a reliable sealing function is achieved with the sealing ring being easy to replace.
  • a manufacturing simplification can be achieved in that the conical valve seat surface of the drain connector for the connecting valve is formed by a widened pipe end of the drain connector.
  • the widened pipe end of the drain connector can advantageously also form the inside of the valve seat for the drain valve.
  • a cover is usually assigned to the drain opening.
  • this can, for example, be arranged together with the valve body of the drain valve by means of an actuating device so that it can be raised and lowered in the closed position, so that the cover with its cover section rests on the inner surface of the trough bottom, while in the open position it has an annular gap of a defined width as a flow opening Drain opening releases.
  • an actuating device so that it can be raised and lowered in the closed position, so that the cover with its cover section rests on the inner surface of the trough bottom, while in the open position it has an annular gap of a defined width as a flow opening Drain opening releases.
  • other possibilities of movement of the cover hood are also conceivable.
  • the single figure of the drawing illustrates in vertical section a whirlpool tub having the invention in the area of the drainage device.
  • the drain device 10 is provided in the region of a recess 24 in the tub base 1.
  • a discharge sleeve 25 is inserted into the recess 24, which defines a drain opening 12.
  • the drain opening 12 opens into a connection chamber 15, from which laterally a piping system 2 branches off, which is intended for the supply of water and / or air to at least one nozzle (not shown) which opens into the interior of the tub.
  • the functionality of the whirlpool pool device is that during operation the amount of water which is injected into the interior of the tub via the whirl pool nozzle is returned via the drain opening 12 back into the pipeline system 2, in which a circulation pump (not shown) is located for this purpose.
  • connection valve 20 Between the drain opening 12 and the outlet opening 26 of the connection chamber 15 into the piping system 2 there is a connection valve 20.
  • the connection valve 20 has a valve body 21 which coaxially coaxially projects into the connection chamber 15 from below, which in turn opens into a drain line 17 surrounds.
  • the valve body 21 is guided with a downwardly projecting sleeve section 27 on a guide section 23 of the drain connector 16.
  • the valve body 21 of the connection valve 20 carries a sealing ring 22, which has a U-shaped radial cross section and acts on the upper end of the valve body 21, from which sealing lips 7 and 8 protrude radially outwards and radially inwards.
  • the sealing lips 7 and 8 work together with valve seat surfaces 4 and 5, which are formed on the one hand on the connection chamber 14, and on the other hand on the drain port 16.
  • the valve body 21 of the connecting valve 20 is pressed by a closing spring 3 in the closing direction, so that the sealing lips 7 and 8 are pressed against the conically inclined, frustoconical valve seat surfaces 4, 5.
  • the spring 3 designed as a helical spring is arranged in a recess 6 coaxially surrounding the drain connector 16 between the drain connector 16 and the valve body 21 of the connection valve 20, also coaxially with the connector 16 and surrounding it, by being on annular shoulders 28, 29 of the drain connector 16 and the Valve body 21 supports.
  • the taper of the valve seat surface 5 at the upper end of the drain connector 16 is formed by a widened pipe end of the drain connector 16.
  • a suitable valve seat 9 is simultaneously realized in the drain connection 16, against which a valve body 11 of a drain valve 18 can be sealingly adjusted. This is done, for example, by means of an actuating device 19 which is rod-shaped in the case shown and whose adjustment possibility is indicated by a double arrow.
  • a cover 13 is also adjusted in the exemplary embodiment shown, which with its cover section projecting over the drain opening 12 with the inner surface of the trough base 1 releases a more or less wide defined annular gap as a passage opening depending on the height position.
  • connection valve 20 has a valve body 21 which is guided on the discharge connection 16 and which is pressed under the action of the closing spring 3 in the direction of its sealing seat and that the sealing seat is constricted in the closing direction by valve seat surfaces 4, 5 of the connection chamber wall 14 or of the drainage pipe 16 is formed, the valve body 21 immediately lifts off from the valve seat surface 4, 5 when the circulation pump in the pipeline system 2 is suddenly switched on against the action of the closing spring 3 which is equipped with low spring force.
  • the valve body 21 of the connection valve 20 quickly reaches the opening position shown in dashed lines, with the participation of the flow of water entering the drain opening 12, for example via radial channels of the cover 13, which is maintained during operation of the whirlpool device.
  • the valve body 21 of the connecting valve 20 is immediately brought back into the higher closed position shown.
  • the negative pressure arising above the valve body 21 when the drain valve 18 is opened cannot be seen to open the connection valve 20, since the valve body 21 is only drawn more into its sealing seat.
  • the pipeline system 2 is hermetically sealed when the bathing water is drained into the drain line 17.
  • the interior A cleaning and disinfection solution can then be added to the piping system 2, which solution can remain in it until the next use of the whirlpool bath, as a result of which cleaning and disinfection liquid also remains applied to the interior of the connection chamber 15.
