DE60201158T2 - Drainage for massage bathtubs - Google Patents

Abstract

Water discharging device for hydromassage tubs actuated by a driving cable (6) to which a pawl (3) is attached that moves the stem (7) of a plug in vertical direction. Together with the pawl the driving cable also moves the swinging link (4) that switches a solenoid valve (20) which opens and closes the connection between outlet (22) and the inlet to the hydraulic circuit (21). <IMAGE>

Description

BACKGROUND THE INVENTION

The The present invention relates to a water drain, in particular was developed for use with massage bathtubs.

massage bathtubs are known usually a hydraulic circuit with outlet openings for the supply of Water in the bath with the help of a feed pump in conjunction with the Inside of the bathtub.

In earlier solutions However, when you drain water from the bathtub, the water will go out the hydraulic circuit is not emptied, since the hydraulic circuit normally is placed at a level lower than that of the Bathtub.

Out For this reason, an undesirable amount of backwater remains in the hydraulic circuit, which can be a source of bacterial contamination.

in the Document US-5 381 831 discloses a drainage according to the preamble of claim 1.

SUMMARY THE INVENTION

Accordingly The object of the present invention is to solve the above problem in particular, by providing an outflow of water for massage bathtubs was developed and with which this problem can be completely solved can, by causing backwater avoided by water and thereby the hygienic conditions the bathtub to be improved.

in the Under the above objective, the main objective of the present Invention in to provide a drainage, operated in such a way that can be an automatic emptying of the entire water in the bathtub and in the hydraulic circuit that supplies the massage bathtub, guaranteed can be.

One Another object of the present invention is to provide a drainage to offer due to the specifically designed construction very reliable and is safe in its application.

One Another object of the present invention is to provide a drainage to provide that easily using readily available elements and materials can be constructed.

One Another object of the present invention is to provide a drainage which is very competitive from a purely economic point of view.

According to one Aspect of the present invention will be the purposes mentioned above objectives and other objectives, which will become clearer in the following, implemented with a water drainage according to claim 1.

SUMMARY THE DRAWINGS

Further Features and advantages of the present invention will become apparent below by the comprehensive description of the preferred, but not exclusive, embodiment a water drainage according to the invention clearly, in particular for Massage baths was developed and in the accompanying drawings is shown, wherein:

1 a schematic detail view of the water drainage according to the present invention is;
and

2 an electrical and hydraulic diagram of the water drainage according to the invention is.

DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to the reference numbers of the above figures, the water drainage according to the invention, which has been developed especially for massage bathtubs, and which is generally identified by the reference number 1 is called, an operating device for the drainage 2 with a pawl 3 on, connected to a swinging connection 4 is coupled, which in turn to a cable 5 coupled, which in a sheath 6 is slidable and to open the drain of the massage bathtub by lifting the stopper 7 in the pawl 3 engages, is driven.

The plug 7 is displaceable in a per se known manner in a terminal block 8th for coupling the emptying element 9 to the lower emptying agent 10 accommodated.

The main feature of the invention is that on the coupling connection 4 the drainage drive element 2 a loading actuating element is mounted, which in the illustrated embodiment, a permanent magnet 15 which is in an open position with a sensor 16 cooperates, which is formed for example by a reed relay.

The latter drives a solenoid valve 20 on, which is the opening of the emptying means of Hydraulikkrei Ses the massage bathtub controls, said drainage means an inlet 21 which is coupled to the hydraulic circuit, and an outflow 22 leading to the underground water drainage channel 10 leads.

In the above-described device is at the opening of the stopper 7 the massage bathtub the pawl 4 vibrated, causing the reed relay accordingly 16 is actuated and the solenoid valve 20 is driven to open the hydraulic circuit, whereby a complete drainage is ensured.

The above actuator can also have a web which actuates a sensor having a microswitch which is arranged in a sealed housing to the solenoid valve to press and drive.

Out The above description should be apparent that the Invention fully fulfills the intended purposes and objectives.

Especially should be pointed out to the fact that the water drain according to the present Invention when opening of the stopper the massage bathtub an automatic and simultaneous pressing of Solenoid valve allows which opens the drainage means of the hydraulic circuit.

On this way, the water from the hydraulic circuit and the pump automatically drained, thereby avoiding a backlog of water becomes, the undesirable odors and can cause bacterial contamination.

The described invention may have various changes and variants, which are all included within the scope of the invention.

Of Further can All structural details are replaced by other technically equivalent elements.

at the practical execution There are no limitations on the materials used in the invention as well as the possible Size and shapes that depend on the requirements.

Claims (2)

Water drainage ( 1 ) for massage bathtubs, where the drain is a stopper ( 7 ), wherein the plug has an open position in which the bathtub is emptied, and a closed position in which water is held in the bathtub, the plug being attached to a pawl (FIG. 3 ), which is connected to an oscillating connection ( 4 ), which in turn to a drive channel ( 5 ), wherein the oscillating connection ( 4 ) Operates switching means which switch a valve which controls the opening of evacuation means ( 21 . 22 . 10 ), which are connected to the hydraulic circuit of the bathtub, characterized in that the valve is a solenoid valve ( 20 ) is that the switching means a permanent magnet ( 15 ) and a reed relay ( 16 ) which are arranged so that the reed relay ( 16 ) the valve switches to an open state when the stopper ( 7 ) and it switches to a closed state when the plug is closed. Drain according to claim 1, characterized in that the permanent magnet ( 15 ) by an end portion of the oscillating connection ( 4 ) is held.
