Definitions

  • the invention relates to a bathtub or swimming pool (so-called whirlpool) with a device for injecting air and water through nozzles arranged below the water surface, the water being conveyed by means of a pump and the air being conveyed by a blower and / or by the Venturi effect is carried out and processes for their cleaning.
  • bathtubs or small swimming pools are often operated as so-called whirlpools.
  • Air, water or a mixture of both media is injected by a pump or a blower under pressure through nozzles introduced into the basin at the bottom and edge below the water surface, so that massaging currents occur and the blown-in air bubbles up.
  • nozzles suitable for dispensing one of the media as well as nozzles with two connections which can dispense both air and water simultaneously or alternately.
  • the nozzles are connected at the end to one or more ring lines running around the basin, i.e. the lines each serve to act on a plurality of outlet openings arranged at a distance from one another.
  • the ring line it is necessary for the ring line to have a sufficiently large diameter so that no pressure drop arises in its interior, which would lead to a differently strong flow through the individual nozzles.
  • the nozzles cannot be arranged in many areas of the basin, or can only be arranged with great difficulty, and their minimum distance corresponds to the diameter of the ring line.
  • the assembly of the nozzles is complex due to a rigid connection to the ring line and must be carried out with high precision.
  • the invention has set itself the task of developing a whirlpool, in which a simple assembly of the nozzles in any arrangement is possible and a uniform flow through all nozzles is guaranteed.
  • This object is achieved in that the medium conveyed by the pump or the blower is directed into a distributor, the distributor is connected to each nozzle by a separate line of approximately the same flow resistance and the flow resistance of the connecting line between the pump or blower and the distributor is smaller than between the distributor and the parallel connection of the Is nozzles.
  • the centerpiece of the proposed whirlpool is a distributor into which the medium conveyed by the pump or the blower is directed.
  • the distributor is connected to each individual nozzle by a separate line, the lines having approximately the same flow resistance with one another, that is to say generally being approximately the same length.
  • a whirlpool with a comparatively large water depth it is possible to choose a lower flow resistance to nozzles arranged on the bottom in order to compensate for the influence of the water pressure.
  • the flow resistance of the connection between the pump or blower and the distributor is expediently significantly lower than between the distributor and the nozzles. In practice, this means that the medium is led through a large pipe cross section to the distributor, which is arranged in such a way that the feed lines to the nozzles with a small pipe cross section and a correspondingly high flow resistance can be made as short as possible.
  • the whirlpool according to the invention has the advantage that it opens up the possibility of simple and rapid assembly of the nozzles at any position.
  • the connection with the distributor prevents the formation of pressure gradients and ensures a uniform conveying of the medium through all the nozzles arranged in the different areas of the tub.
  • the venturi effect or a blower can alternatively introduce air into the whirlpool. While in the latter case the nozzles can also be charged with pure air, there is always the option of introducing water or a water-air mixture.
  • the feed lines of the nozzles originating from the distributor consist of a flexible material.
  • the distributor is expediently arranged with a spatial gradient to the nozzles, ie it is approximately at the level of the intended water surface of the whirlpool or above it.
  • the distributor is preferably located at the highest point of the water-loaded lines and also has a slope to the pump. After the pump has been switched off and, if necessary, the water has been drained from the tub, any liquid remaining in the distributor and its feed line runs through the nozzles into the whirlpool, so that there is a risk of Propagation of bacteria or fungi is reduced. In contrast to a large-volume ring line arranged at the height of the nozzles, complete emptying of the distributor is ensured, with minimal quantities of residual water remaining in the substantially smaller volume of the connecting lines to the nozzles.
  • the flow resistance of the line system and thus the efficiency or the energy consumption of the pump required for operation can be significantly improved by equipping the trough with several distributors, preferably having two distributors arranged on opposite sides.
  • the feed lines of the nozzles which have a small cross section, can thus be shortened at the expense of the length of the lines between the pump and distributor, the flow resistance of which is largely negligible.
  • the arrangement of round basins is largely arbitrary, it is advisable to attach the distributors on the long sides of a whirlpool in the form of a bathtub. In the case of a large-volume whirlpool in particular, there is the possibility of further increasing the effectiveness by using more than two distributors.
  • a blower is advantageous in addition to a pump, with which air can be pressed into the pipe system.
  • a check valve after the blower.
  • a simple and reliable design consists of a ball made of floatable material, which is in the form of a fan is arranged vertically downward line that it causes a watertight seal when floating, ie when a large amount of water penetrates.
  • the whirlpool is equipped with separate pipes and distributors for both media. In this way, a safe supply of air and water to the nozzles in the desired amount can be achieved in a simple manner and the noise level during operation can be considerably reduced.
  • preferred nozzles are those which are connected to both line systems and are suitable for dispensing both media at the same time.
  • the bridge line has a valve which closes when the line system for water is pressurized by the pump and thus prevents water from penetrating into the line system for air. If the latter is pressurized by the blower, the valve opens only when the line system for water is depressurized, that is, the pump is switched off. It is therefore still possible to operate the pump and blower at the same time without water being able to penetrate the air duct system.
  • a pressure switch which is connected to the bridge line, is preferably arranged between the check valve arranged downstream of the blower and the valve in the bridge line. If the valve in the bridge line fails, water penetrates and causes the check valve to close, whereby the pressure in the bridge line increases and exceeds the maximum delivery pressure of the blower, which is generally considerably lower than that of the pump. In this case, the pressure switch expediently brings about an emergency shutdown of the pump.
  • a pressure switch integrated in the bridge line which is connected to the pump via an electrical line, and the connection of the bridge line with a hose to a pressure switch arranged in the pump are conceivable.
  • the whirlpool is preferably equipped with nozzles or nozzle heads which can be removed from the nozzle body and which are detachably fastened from the inside of the tub. While maintaining the supply system, different flow patterns can thus be generated with little effort, the range of variation being expandable by the optional application of air or water. In addition, the maintenance effort of the system is considerably reduced due to the easy accessibility of the nozzles.
  • the hot water in the whirlpool offers excellent conditions for the fungi and bacteria it contains, especially if it has been in the pipe system for a long time. For this reason, regular and thorough cleaning should be sought.
  • a simple method in a whirlpool equipped with a fan is to press water through the line system under pressure and with a large excess volume of air. With this procedure, dirt that is stuck on the inside of the line can also be easily removed.
  • a cleaning medium for example a disinfectant to inhibit the growth of microorganisms or a lime-dissolving acid.
  • Drying of the pipe system can be achieved by blowing air through with the blower when the tub is empty.
  • the particular advantage of this procedure arises in connection with the small diameter of the feed lines to the nozzles, so that any water remaining in them can be squeezed out completely. Even with separate piping systems for air and water, it is possible to empty the water-filled system in this way if both media exit through the same nozzle of suitable geometry.
  • the effect also arises from the Venturi effect, that is to say that the air emerging from the nozzle at high speed creates a negative pressure and thus sucks out any water remaining in the other pipe system.
  • the drawing shows a schematic representation of a Whirlpools according to the invention, which consists of a tub (2) filled with water (1), which can be pressurized with air or water under pressure by means of a pipe system and nozzles (3) below the water surface.
  • the pipe system is divided into two sections, each of which is used to apply a medium.
  • the central component of both sections is a distributor (4, 12), which is connected to the nozzles (3) mounted in the tub (2) via flexible lines (5, 13) which have approximately the same flow resistance in each section.
  • the distributors (4, 12) are expediently arranged approximately in the region of the surface of the water (1) or above, so that there is a gradient to the nozzles (3) and water remaining in the system can run off after the system has been switched off.
  • Water is conveyed into the distributor (4) by means of a pump (6) arranged below, which pumps it out of the trough (2) via a suction line (7) and into a connecting line (8) with a large cross-section and correspondingly low flow resistance pumps.
  • a blower (9) is used to pressurize air drawn in from the environment, which it presses through the feed line (14) into the distributor (12), downstream check valves (10) protecting the blower (9) against the ingress of water.
  • a suitable embodiment consists, for example, of a ball made of floatable material, which closes vertical lines in a watertight manner when floating.
  • the blower (9) allows the entire line system to dry, with residual water remaining almost completely being blown out due to the small diameter of the lines (5, 13).
  • a bridge line (15) is used to connect the two sections of the line system, so that the air can also reach the part to which water can be applied.
  • the bridge line (15) is provided with two safeguards to protect water from entering the blower (9).
  • a check valve (10) described above is followed by a further valve (16), which is closed when the pump (6) is operated and pressurizes the distributor (4).
  • valve (16) fails due to a defect, it closes above it arranged check valve (10), so that the part of the bridge line (15) located between the two valves (10, 16) is put under pressure during operation of the pump (6) which exceeds the delivery pressure of the blower (9) and a pressure switch ( 17) triggers, which is connected to the pump (6) via a cable (18).
  • the triggering of the pressure switch (17) causes it to be switched off, so that there is further protection against the ingress of water into the blower (9).
