The invention relates to an under-shower device comprising a housing, a water tank arranged in the housing, a device for conveying the water arranged in the housing, a detergent tank, a

Detergent pump and a shower head with outlet nozzles.

From the prior art, for example DE 87 90 79 B, DE 1 779 795 U, DE 27 029 27 Al

Under shower devices known, which are designed as a structural unit with a water closet (WC), as a stationary separate device or as an attachment for a toilet.

In addition, are already portable

Under-shower devices have become known, which are suitable for mobile use without connection to a toilet, a toilet room or a toilet lid.

WO 00/55438 discloses a transportable

Under-shower device with several tanks, which optionally, for example, water, soap and disinfectant solution

take up. A controller controls the individual tanks

assigned pumps and mixes the different

Liquids, the liquid mixture being conveyed to a shower head via a common hose. The shower jet is operated via control elements of a control arranged on the housing. The energy supply of the pumps, the control and the heating element for the

Water tank requires an external power connection. If the mobile under-shower device is to be used on a toilet, operation on a control arranged on the device housing is a problem. In particular, it is not without problems that it is possible to switch back and forth between the supply of soap and water. It is also difficult to interrupt the spray of the shower head. Finally, the under-shower device is only suitable for mobile use to a limited extent, since an external power connection is absolutely necessary.

DE 203 12 736 Ul discloses a mobile

Under-shower device with a multi-chamber tank, the chambers of which contain soap and water. Using a single pump, soap and water are conveyed from the tank via a hose line to the shower head, the

Spray nozzles can be closed individually. The one by one

closable nozzles of the shower head only allow to control the total supply of the mixture of soap and water.

GB 2 336 533 A discloses an under-shower device which has a water tank in a housing which can be closed with a lid, the water contained in the water tank being heatable by means of a heating element. Detergent can be added to the water, which is then added to the shower head as a mixture via a pump.

US Pat. No. 6,968,580 B1 discloses an under-shower device in which water from a heated water tank is passed over a

Spiral hose to a shower head with a lever nozzle is conveyed by a pump. The device has a external energy supply and is therefore only suitable for mobile use to a limited extent.

Based on this prior art, the object of the invention is to create an under-shower device which is suitable for mobile use and is easy to operate and in which the supply of cleaning agent and water can be controlled separately. Furthermore, an under-shower device that is suitable for mobile use and does not require any electrical energy is to be proposed.

The solution to this problem is based on the idea that

Operation for the targeted supply of water and

Shift cleaning agents and their mixture into the shower head. In a particularly preferred embodiment of the mobile showering device, it does not require any electrical energy.

In particular, the object is achieved in an under-shower device according to the preamble of claim 1 in that the detergent tank is arranged in or on the housing,

a manually operated valve control is arranged in the shower head, the valve control having a first inflow connection, a second inflow connection, and an outflow connection,

the first inflow connection via a first

Hose line fluid-conducting with the water tank and the second inflow connection via a second Hose line fluidly with the

Detergent tank is connected,

the drain connection is connected in a fluid-conducting manner within the shower head to the outlet nozzles and the valve control is set up to temporarily interrupt the supply of water and / or cleaning agent to the outlet nozzles.

The mixture of water and cleaning agent takes place between the two inflow connections and the outflow connection, preferably in a mixing chamber provided for this purpose.

The valve control can be brought into a first, second and third switching position. In the first switch position, the flow paths between the two inflow connections and the outflow connection are interrupted. In this

Switch position no water or cleaning agent reaches the outlet nozzles of the shower head. In the second

Switch position is only the flow path between the first inflow connection for water and the

Drain connection open. In this switch position, only water gets to the outlet nozzles of the shower head. The flow paths are in the third switch position

between the two inflow connections for water and

Detergent and the drain connection open. Water and cleaning agent enter the mixing chamber of the directional control valve and from there via the two inflow connections

Water / detergent mixture to the drain connection, which is fluidly connected to the outlet nozzles of the shower head. A major advantage of the solution according to the invention is that not only a water / cleaning agent mixture, but also clear water is obtained via the shower head

can be supplied, with simultaneous easy operation of all functions using the in the shower head

arranged, manually operated valve control. The

under-shower device according to the invention allows a

one-handed operation. Operating operations on the control elements of the housing of the under-shower device are not necessary during the showering process, so that a significantly higher operator ergonomics with improved at the same time

Operational safety is achieved. In particular, the improved operation prevents uncontrolled spraying of water or water / detergent mixture during the shower process.

In one embodiment of the invention, the valve control can comprise separate valves for the water and the cleaning agent, with which the flow path of water can be defined

and / or detergent can be temporarily interrupted.

In a constructively advantageous embodiment of the

According to the invention, the valve control only comprises a valve which is designed as a manually operated directional valve (three-way valve). The directional control valve has one between the drain connection and the two inflow connections

arranged mixing chamber and a control element, wherein the control element into a first, second and third

Switch position can be brought. In the first switch position, the flow paths between the two inflow connections and the outflow connection are interrupted. In this switch position, neither water nor cleaning agents are added the outlet nozzles of the shower head. In the second switch position, only the flow path between the first inflow connection for water and the

between the two inflow connections for water and

Drain connection, which is fluidly connected to the outlet nozzles of the shower head.

The directional control valve can be moved into the three switch positions by means of a single actuator, so that the operator can change the composition or

Interruption of the spray jet during the shower process can easily change with one hand. A special one

space-saving arrangement of the directional valve at the same time

easy handling by a sliding movement of the

Actuator is achieved when the control element of the directional control valve comprises a valve slide. The valve slide moves along a longitudinal axis of the shower head. However, the control element can also be designed as a rotary slide valve.

To drive the device to promote the

To use water to convey the detergent at the same time, the detergent pump is preferably as

Water jet pump executed, which is integrated in the valve control, in particular the mixing chamber of the directional valve. The water entering the mixing chamber of the directional valve is also used as a propellant for the liquid

Detergent used. The the detergent

Conveying water jet pump does not require any electrical energy. At the same time, the cleaning agent is effectively mixed with the water in the mixing chamber before the water / cleaning agent mixture reaches the outlet nozzles of the shower head via the drain connection.

The water jet pump can be advantageously integrated into the directional control valve, in which the water jet pump has a nozzle pipe with an inlet opening and an outlet nozzle, and the nozzle pipe with the outlet nozzle in the

Mixing chamber of the directional valve opens and lies in the flow path between the first inflow connection for water and the outflow connection of the directional valve, the mixing chamber surrounds the nozzle tube to form an annular space and the annular space in the flow path between the second inflow connection for the cleaning agent and the outflow connection of the directional valve.

At its outer boundary, the mixing chamber has a negative pressure connection which opens into the annular space

Detergent on the fluid-conducting with the second

Inflow connection is connected, the fluid-conducting connection in the directional valve through the control element

is closed or opened. Between that quickly

flowing water jet and the surrounding liquid

Cleaning agents are caused by friction, turbulence, which causes the water and cleaning agent to mix well. In this process, the kinetic energy of the water jet is also transferred to the surrounding detergent, making an effective conveying mechanism for the Detergent is available from the detergent tank via the second hose line to the outlet nozzles of the shower head.

The detergent pump can also be used as a water jet pump in the case of a valve control with separate valves for controlling the flow path of water and detergent

be executed. The water flows in the direction of flow behind the first valve for controlling the flow path of water through a nozzle pipe into a mixing chamber

Valve control initiated. The mixing chamber surrounds this

Nozzle tube with formation of an annulus and the annulus lies in the flow path between the second inlet connection for the cleaning agent and the outlet connection of the

Valve control. The mixing chamber has on its outer

Limit one opening into the annulus

Vacuum connection for the cleaning agent on the

fluid-conducting with the second inflow connection for the

Detergent is connected, the fluid-conducting

Connection is closed or opened by the second valve for controlling the flow path of detergent.

To also the device for pumping the water without

Being able to operate electrical energy is all in one

advantageous embodiment of the invention provided that the device pressure-tight the water tank

lockable fuel cap and a manually operated

Air pump that is used to increase the pressure in the

Water tank is set up. How the

Conveying device for the water corresponds to that of one

Pressure sprayer. First, the The required amount of water is poured into the shower. Then, by operating the air pump, the pressure in the water tank designed as a pressure vessel is increased so that the water is conveyed through the first hose line to the shower head. If the detergent pump as

Water jet pump is executed, no electrical energy is required for the delivery of water and detergent to the shower head.

To facilitate the handling of the under-shower device when filling the water tank with water, the

Tank cap and the air pump in advantageous

Embodiment of the invention an assembly. To fill the water into the tank, the assembly is released from the filler neck of the tank, preferably via an upper housing opening. After filling, inserting the

Assembly at the same time the air pump with its pressure side in the water tank effective.

The water is preferably filled into the water tank at body temperature or a slightly higher temperature. In order to reduce cooling of the filled water in the water tank, the water tank advantageously has

Embodiment of the invention on thermal insulation. With such a configuration of the water tank, an additional heating element which requires electrical energy to heat the water in the water tank can be dispensed with when the water tank is filled daily.

If the under-shower device has a water jet pump, a device for conveying the water with a hand-operated air pump and a heat-insulated water tank, an under-shower device is created that is particularly suitable for highly mobile use without any electrical energy. The under-shower device is particularly light, since an electrical energy store can be dispensed with. Due to the absence of an electrical

Energy storage also results in more compact dimensions. Added to this is the robust, almost wear-free and therefore less prone to failure for mobile use

Technology.

Of course, the invention

Detergent and / or water pumps. If the under-shower device according to the invention only has an electrically driven water pump, the detergent pump is preferably designed as a water jet pump integrated in the shower head. This combination also results in significant weight and

Advantages of installation space, since the electrical energy store that only drives the water pump can be dimensioned smaller and no installation space in the housing for an electrical one

Detergent pump is needed.

The electrical energy store accommodated in the housing is preferably a rechargeable storage for

designed electrical energy. Operation of the

Under-shower device therefore does not set any electrical

Connection for the operation of the pumps during the

Showering ahead. The switches for switching on / off the electrical energy for operating the cleaning agent pump and / or water pump are preferably arranged on the housing of the under-shower device in order to be laid to avoid electrical lines along the hose lines to the shower head. The on the housing for the

Pumps switched on in the shower mode work against the

Valve control in the shower head, if the supply of water and / or cleaning agent is temporarily interrupted by the valve control.

To continue the hose lines to the shower head

simplify, in an advantageous embodiment of the invention the smaller diameter hose line for the cleaning agent is guided within the larger diameter hose line for the water. The water supplied to the shower head flows exclusively through the annular space between the outer jacket of the second

Hose line and the inner jacket of the first hose line, while the cleaning agent is passed exclusively through the second hose with a smaller diameter.

If the detergent tank is not located in, but on the outside of the housing, this can easily be carried

Detergents, e.g. a mild soap solution, filled or replaced by a filled detergent tank. The detergent tank is especially as

Disposable tank designed, which is replaced by a filled, new detergent tank after emptying. The detergent tank can be accommodated, for example, in a receptacle that is accessible from the outside, for example a housing cut that at least partially accommodates the tank. If the detergent tank is at least partially transparent, the fill level can also be easily checked. An electrically operated heater can be provided to temper the shower water. Preferably, however, the preheated water in the water tank is only kept at temperature by the thermal insulation. Is a

provided electrical heater, it is arranged in the housing and supplied by the electrical energy storage. The heater can be designed as a water heater, the inlet with the pressure side of the water pump and the

Output are connected to the first hose line. The instantaneous water heater does not require any maintenance energy, is compact and protects the energy storage.

The water tank can be filled in an alternative

Embodiment of the invention can be temporarily removed from the housing. For this purpose, the water tank can be pulled out of the housing in the manner of a drawer or removed via an opening which can be closed with a lid and filled outside the housing. The water tank preferably has a capacity of about 5-10 liters.
