The invention relates to a filling and emptying battery for a boiling water device with a in the installation position going out backwards Cold water inlet, an outgoing Device connection for the boiling water device, one downward-facing outlet hole a swivel spout and operated from the outside adjustable actuators for the optional connection of Cold water inlet and outlet or boiling water device and spout, and one on the boiling water device arranged overflow pipe, the overflow pipe in the Exit bore opens into which the Water outlet channel of the battery opens out.

In the prior art there are filling and emptying known batteries in which the overflow pipe is constantly freely connected to the atmosphere, to prevent overpressure from building up inside of the otherwise closed boiling water device builds up. Such, for example, by the  DE-GM 19 25 377 known filling and emptying batteries have the disadvantage that the overflow pipe under side of the boiling water device opens freely, so that in addition to the actual water outlet through the Swivel spout is formed, another water outlet or a hot steam delivery point is formed.

The DE-GM 18 63 339 is a filling and drain battery known in which the Overflow pipe already opens into the outlet bore, in which is also the water outlet channel of the battery flows. With this arrangement, a functional malfunction occur because it is possible that the function the overflow pipe is affected by water, which through the water outlet channel of the battery opens into the battery exit hole. Such a malfunction is undesirable because they cannot ensure that the overflow pipe is completely freely connected to the atmosphere.

Based on this state of the art Invention the task of filling and To create a drainage battery of the type mentioned at the beginning,  in which the overflow pipe into the filling and Drain battery is integrated, however, a Impairment of the function of the overflow pipe Water flowing through the water outlet channel is excluded.

To achieve this object, the invention proposes that one of the two mouths is axial and one is radial or both mouths radially into the outlet bore flows or flow, and that in the exit hole usable swivel spout an axial mouth and one radial mouth or two radial mouths which is in the installation target position with the mouths of the overflow pipe or water outlet channel communicate, are sealed against each other and via separate channels in the swivel spout to each other separate discharge openings of the same are guided.

The fact that the overflow pipe in the outlet bore opens into which also the water outlet channel of the battery opens on the one hand an integration of the overflow pipe  or its connection to the battery or reached the battery body.

In addition, the inventive Arrangement of the overflow pipe with its mouth arranged so that it is independent of the Fixed movement of the swivel spout is.

Due to the axial or radial arrangement of the Mouths is relative to the exit bore a safe separation of the waterway from the Overflow path reached, with corresponding Channel training ensures that the Function in any swivel position the swivel spout is guaranteed.

Due to the separate ducting up to the separate delivery openings of Overflow and water outlet is also out concluded that an impairment of the Overflow from the battery  escaping water can enter.

It is also preferably provided that the Delivery opening of the water outlet channel on free end of the swivel spout and under is open-ended and the levy Opening of the overflow pipe parallel to the axis between the free end and the pivoted one End of the swivel spout is arranged.

This training ensures that the operator when removing water not accidentally caught up in hot steam or Water can hurt from the overflow pipe through the fitting to the corresponding one The discharge opening flows and exits there.

It is a preferred further training seen that in the exit hole usable end of the swivel spout as Pipe socket is formed and two with  Distance from each other sealing rings has, the sealing seats an annular chamber form and between which the radial mouth in the swivel spout is arranged while the axial mouth formed by the free end of the pipe socket is.

Furthermore, it is preferred that the pivot outlet after the vertically arranged Pipe socket with a horizontal outlet part has the discharge openings on the underside.

To achieve that in the swivel spout water even after closing the corresponding actuators completely flows, it is provided that the overflow pipe in the axial mouth of the pipe socket of the Swivel spout opens, the radial mouth of the pipe by an internal wall part  of the swivel spout opposite the axial mouth of the pipe connector separated to form a double channel is and in the immediate vicinity of the axial A vent in the wall part bore is formed.

At a boiling water device 1 of conventional construction, a filling and emptying battery 2 is connected on the underside, which has a swivel outlet 3 with a discharge opening 4 . Furthermore, an overflow pipe 5 is connected to the boiling water device 1 , which is connected to a discharge opening 6 of the swivel spout 3 in a manner described in more detail later.

A bellows 7 is arranged between the boiling water device 1 and the battery 2 to cover connecting parts.

The battery 2 has a rotary handle 35 for a cold water valve in the view on the right and a rotary handle 36 for a hot water valve in the drawing on the left side. The battery 2 has a battery body denoted by 9 , which has a cold water inlet 8 going out towards the rear.

In the cold water inlet 8 , a throttle screw 10 is used accessible from the outside. At the cold water inlet 8 is followed by a cold water channel 11 , which is connected via a cold water pipe 12 with the cold water inlet 13 of a butterfly valve 14 . The disk valve 14 is connected via a cold water outlet 15 to the boiling water device 1 , the water then flowing through connection channels 17, 17 ' and a device connection pipe 18 into the boiling water device 1 .

The device connection tube 18 is connected to the battery body 9 by means of a device connection screw 19 . Alternatively, by means of the disc valve 14, the cold water inlet 13 can also be connected to a further cold water outlet 16 , which passes via an outlet channel 23 and a water inlet channel 24 into an outlet channel 25, 25 'of the swivel outlet 3 and exits at the discharge opening 4 .

To the left of the fitting (see FIG. 3) is a hot water valve 21 with the rotary handle 36 , which controls the flow of hot water coming from the boiling water device 1 to the discharge opening 4 .

When the hot water valve 21 is open, the water heated in the boiling water device 1 flows through the device connecting pipe 18 and the connecting channels 17, 17 ' through the hot water inlet 20 of the hot water valve 21 into the valve chamber 22 and already there via the outlet channel 23 , the water outlet channel 24 and the outlet channel 25 , 25 ' in the swivel spout 3 towards the discharge opening 4 .

It is clear that in open hot water valve 21 cold water 14 can be mixed additionally by opening of the cold water influencing the disc valve.

The swivel spout 3 with a pipe socket 28 can be inserted into a downward-directed outlet bore 29 of the battery body 9 .

In this outlet bore 29 , in particular in a connection chamber 26 arranged above the outlet bore 29 , the overflow pipe 5 opens in a sealed manner. When the swivel spout 3 is inserted, the connecting chamber 26 is connected via an initially axially extending overflow channel 27 and via an essentially horizontally adjoining overflow channel 27 ' to the discharge opening 6 of the swivel spout 3 . The water outlet channel 24 opens radially into the outlet bore 29 and is connected via a radial opening of the pipe socket 28 with the outlet channels 25, 25 ' and the discharge opening 4 in connection. In the wall part, which separates the outlet channel 25 and the overflow channel 27 from each other, a ventilation hole 30 is provided above, which serves as a compensating hole and the Zwangsent emptying the outlet channel 25, 25 ' causes closed valves.

For optical reasons, the battery body 9 is encased by half shells 31, 32 , the wall-side connection (cold water inlet 8 ) along with the throttle screw 10 also being covered by a bellows 33 . The pipe socket 28 has two sealing rings that can be used in U-shaped, circumferential sealing seats. The sealing seats are like the outlet bore 29 sets abge, so that when inserted into the outlet bore 29 pipe socket 28 an annular channel is formed between the two sealing seats, which holds the water outlet channel 24 in connection with the outlet channel 25 regardless of the pivot position of the swivel spout 3 . To fix the mounting position of the pipe socket 28 , a screw 34 is provided, which is screwed through the wall of the battery body 9 and engages under the lower seal seat of the pipe socket 28 , so that its rotational movement is not hindered, but the axial position is secured.

The disk valve 14 is described in more detail below with regard to its internal structure. Reference is made in particular to the drawing figures 9 to 13.

In a corresponding receptacle of the battery body 9 , a cartridge cage 37 is inserted.

The cartridge cage 37 has a cartridge base 38 on which a fixed disk 39 is held non-rotatably.

The fixed disk 39 has a cold water inlet bore 13 which is connected to the cold water pipe 12 . Furthermore, the fixed disc has the cold water outlet 15 and the cold water outlet 16 , one of which leads to the boiling water device 1 and the other to the discharge opening 4 . On the fixed disc 39 , a regulating disc 40 is rotatably arranged, the side of the fixed disc 39 abge is coupled via a driver 41 with a spindle 42 which carries the handle 35 . To fasten the built-in parts, a head piece 43 is screwed into the receiving opening of the battery body 9 on the end face.

The driver 41 , which is operatively connected to the regulating disk 40, has a compression spring 47 and a ball 45 as a detent element in a radially extending recess. The ball 45 protrudes radially from the corresponding receiving opening of the driver 41 and, in the central position, which corresponds to the disk position according to FIG. 11, engages in a locking groove 44 which is formed on the inside of the cartridge cage 37 . In this way, the middle position shown in FIG. 11 becomes noticeably but releasably locked. The receiving bore for the ball 45 and the spring 47 is designated 46 .

The regulating disc 40 has a deflection channel 48 , which, depending on the position of the regulating disc, is either not connected to a bore of the fixed disc 39 or the cold water inlet 13 with the cold water outlet 15 for filling the boiling water device 1 or the cold water inlet 13 with connects the cold water outlet 16 for dispensing cold water from the dispensing opening 4 .

The angle of rotation of the regulating disk 40 is limited so that a maximum rotation into the position shown in FIG. 12 or in the opposite position (connection of cold water inlet 13 and cold water outlet 15 ) is possible.

In order to make it possible to translate the rotary movement of the spindle 42 via the driver 41 onto the regulating disk 40 , a driver shoulder 49 is provided, which brings about the necessary positive coupling during the rotary movement.

Furthermore, 50 is a channel seal and 51 locking lugs for securing the fixed disk 39 .

Through this training is achieved that the overflow on the one hand in the total battery is integrated, whereby on the other hand, it is ensured that the Overflow freely in every functional position communicates with the atmosphere so that Escape steam or overflowing water safely can.  

There is also a separation between overflow and normal water outlet guaranteed what perfect and safe operation is preferred and advantageous.

The disc valve enables the optional delivery of cold water for boiling water device or to the outlet, whereby also on the one hand a path limitation in both turns directions is reached and on the other hand which is not visible to the user or noticeable middle position by a spring catch is noticeable and therefore adjustable.
