EP0682932B1 - Jet orienting device for hydromassage nozzles - Google Patents

Abstract

The hydromassage unit has a nozzle (4) that is larger than a cone-shaped discharge channel (14). In the absence of additional influences, the jet issues in a central position. Deflection of the jet is generated by the introduction of control flow at right angle (13) to the jet to produce the massaging effect. The flow can be pulsed by the operation of a valve. Control jets on opposite sides produce a bistable action. <IMAGE>

Description

The invention relates to a method for controlling a preferably in a sanitary Pool arranged hydromassage nozzle, one through the courtyard of the massage nozzle flowing through first fluid in this with at least one second fluid to form a an air-water mixture existing massage jet is applied.

In the area of sanitary facilities are devices for irradiation of pressurized liquid and / or gaseous media, in connection with a sanitary water basin, such as Shower bath, whirlpool, swimming pool or exercise pool, in a stationary or mobile arrangement known. The jet that can be emitted from such devices serves the purpose of treating the human body. In such devices, it is advantageous that the direction of the emittable beam is orientable that the emittable beam is emitted pulsed and not lastly, that the jet consists of a liquid and a gaseous medium. At acquaintances Devices use the principle of the water jet pump, a water / air mixture to generate which is used to treat the human body in a pool of water water is injected. In these known devices is within one Nozzle housing provided with the driving medium (water) supplyable central nozzle which the driving medium (water) can be dispensed as a free jet and the central nozzle at a distance comprehensive atmospheric ventable ring nozzle is provided from which the trapping medium (air) can be fed, the free jet due to its drag effect that can be dispensed via the ring nozzle Air is sucked in and ventilated all around its circumferential surface. Are also Hydromassage jets known to work on the reverse principle of the water jet pump, the central nozzle can be ventilated when the devices are in use; the driving medium is via the ring nozzle feedable. In both cases, a collecting nozzle (also called a jet pipe) is provided, which can be pivoted, via which the mixture can be dispensed into the water basin.

From DE G 9205316.6 a hydromassage nozzle for a sanitary device is known, whereby the direction of the jet which can be emitted from this single jet nozzle with the aid of mechanical ones Devices can be oriented. This device has the disadvantage that the seal against Loss of water is very expensive. There is a risk of leaks on inaccessible Components. A disadvantage is a complex mechanical drive and maintenance Movement device required, which is largely installed in inaccessible installation areas. The change in the beam orientation disadvantageously takes place in wiping movements which are carried out in the essentially only tangentially hit the body of a bather and therefore only one produce inadequate massage effect. The disadvantage is the change in Beam orientation limited by the mobility of the mechanical drive devices and sluggish.

From US 4,763,367, US 4,715,071 and US 4,710,990 hydromassage jets are known which Have rotatably mounted jet pipes, the jet pipes through the flowing medium in Rotation or roll movement can be offset. Due to the moving jet pipes is on such hydromassage jets are a significant risk of accidents, especially for children. A high jet pressure is required to cause a noticeable jet rotation. Too high Jet pressure causes skin and tissue damage when using underwater massage. The Size of such devices is disadvantageously so large that the mounting wall in considerable disconnection and weakening, which leads to static problems and Problems with sealing leads. A disadvantage of such devices is the fact that when Emptying the tub residual water remains in the devices and this for odor and poor hygiene conditions.

A whirlpool tub is known from EP 0 115 603, in which the one from the hydromassage nozzle dispensable beam is pulsable. A device is provided in the air supply line, which can be operated in cycles, interrupts the air flow. Such a device has the disadvantage that during the period of the air flow interruption, the hydromassage jet only hits a "hard" Water jet ejects, and that the jet emitted from the hydromassage nozzle is always a takes a constant directional orientation.

DE 2511856 A1 describes a spray device for dispensing a gas drawn in mixed liquid jet known. In this device, a central main nozzle is for Delivery of a liquid jet provided in an interaction chamber, in which Interaction chamber both air and water for the purpose of mixture formation are suckable; with a coaxial to the main nozzle, located downstream from a narrowest Cross section of diffuser-like widening collecting nozzle, the narrowest cross section of which is wider than that narrowest cross section of the main nozzle. At least one connection to the Interaction chamber for the supply of gas and additional liquid or at least one Connection for supplying additional liquid from the environment. The main nozzle and the The collecting nozzle has a rectangular cross section. From the description it can be seen that the right half of the interaction chamber has an open wall section which can obviously flow into the interaction chamber in an uncontrolled manner. 3, the outlet of the main nozzle is in the area the narrowest cross-section of the collecting nozzle, an interaction chamber is not intended. Two separate inlets are provided in the collecting area of the collecting nozzle the air and / or water can be sucked in. Means for orienting the direction from the Sprayable dispensable jet are not provided in DE 2511856 A1.

The invention has for its object a method and a device for control of hydromassage nozzles indicate the direction of flow from the hydromassage nozzle dispensable massage jet influenced, without this moving parts of the Hydromassage nozzle are required.

This task is in the method and the device of the type mentioned solved according to the invention in that the flow direction of the massage nozzle emitted massage jet by supplying a certain volume flow of second fluid to the first fluid by at least one at an angle to the direction of flow of the first fluid in control channel opening into the courtyard is changed.

With such a method and such a device, the control of Hydromassage nozzles allows without moving components to change the Flow direction of the massage jet must be used. In this way not only cost-effective production, but also an almost maintenance-free service life achieve.

The advantages you mentioned result from a hydromassage nozzle which has a nozzle housing and an inner courtyard is formed within the nozzle housing, with an outside Supply channel leads into the courtyard, which supply channel with at least one Supply nozzle, which opens into the inner courtyard, which is larger than the supply nozzle Inner courtyard is essentially formed by two at a distance and essentially parallel mutually extending walls which form a flat channel in the direction of flow, wherein the flat channel is laterally delimited by walls of smaller width, downstream the Flat channel has an outlet opening, the side of the supply nozzle opens into the courtyard at least one control channel, through which control channel a certain amount of fluid is supplied to the Inner courtyard can be fed in or removed from the inner courtyard, the directional orientation of the Power jet by the supply or discharge of a certain amount of fluid can be influenced.

The invention is based on the known Coanda effect and the knowledge that a free jet of fluid from its environment carries away fluid with it. However, once fixed limits are present, these can hinder the flow of the surrounding fluid, so that the Pressure in the vicinity of the jet is reduced. The pressure drop is uneven around distributes the jet so that a pressure difference between two opposite one another Beam side occurs, then the beam is due to this pressure difference from its original Deflectable direction.

• als Ringkanal ausgebildet, miteinander in Strömungsverbindung stehen, oder
• als Verbindungskanäle zwischen einem stromab der Versorgungsdüse gelegenen Bereich des Innenhofs und dem Nachbarbereich der Versorgungsdüse ausgebildet sind.

According to variant c), the hydromassage nozzle according to the invention is designed as a multivibrator, the inner courtyard of the nozzle housing in the vicinity of the supply nozzle having two control channel inputs or control channel outputs which are preferably arranged in opposite directions. To which control channel inputs or outputs connect flow channels provided from the outside, which flow channels either:

• can be supplied from the outside with a pulsed control medium, or
• formed as an annular channel, are in flow connection with each other, or
• are formed as connecting channels between a region of the inner courtyard located downstream of the supply nozzle and the neighboring region of the supply nozzle.

As a result of the nozzle effect, when the power jet is supplied, it is expanded laterally A negative pressure can be generated in the area of the inner courtyard. The side walls of the inner courtyard have at least one opening, to which opening a control medium can be supplied Control channel connects. When supplying a control medium that is in the wall of the The opening provided in the inner courtyard can be fed in, the opening formed by the nozzle effect Negative pressure balanced.

In a further variant in accordance with the embodiment of the hydromassage nozzle described under c), the mouth of at least one control channel is provided in the area of the supply nozzle, which control channel can either be supplied with a pulsed fluid from the outside, or is designed as a closed loop, and one on the right and opening to the left of the supply nozzle opens into the inner courtyard of the nozzle housing.
Instead of the ring channel, however, a control channel opening can also be provided at least on one side of the supply nozzle, this opening being in flow connection through a control channel with a downstream inlet opening. The downstream inlet opening protrudes with a wall section into the outflow channel, as a result of which the flow cross-section of the outflow channel is reduced, with part of the power jet being able to be returned through the control channel into the upstream region of the inner courtyard, into the vicinity of the supply nozzle.
In the embodiment of the invention according to the variant described under c), the signals serving to switch the beam can be transmitted in rapid succession to the power beam, so that the orientation of the beam can be emitted with a high cycle rate through the hydromassage nozzle as a multi-vibrator.

In the variant of the hydromassage nozzle described under b) it is provided that within the courtyard at least one upstream jumping into the flow channel directed edge is provided, to which edge is directed a sideways outward Bulge connects, the wall of the bulge having an opening which Opening opens into a sewer.
