Description

SPECIFICATION Household water-conducting installation The present invention relates to a household water-conducting installation including a machine operating with water.
In a known (DE-OS 30 14 427) safety divice against flooding in such an installation, in the event of breakage of an inlet hose of the installation the leadkage water issuing therefrom is conducted by way of the leakage water hose into a collecting trough, where a switching device immediately initiates closure of a liquid inlet. The switching device can be a float-controlled switch by which, on the occurrence of leakage water, the inlet valve is closed and/or an emptying pump of the machine is switched on, the pump being connected by an outlet hose to locally fixed waste water mains.If the inlet valve, for example connected to a stop cock of the water mains, consists of an electromagnetic valve actuable by the control equipment of the machine, then the magnet coil of the inlet valve is connected through an electrical line with the control equipment, for example a program control device and/or a switching device in the leakage water collecting trough of the machine.
The housing of the inlet valve is screwed at an inlet stub pipe thereof to the outlet of the stop cock and fastened to an outlet stub pipe of the valve housing is the inlet hose, which leads by way of a safety valve in the machine to a rinsing container of the machine. Moreover, a leadkage water hose is fastened by means of a hose clamp to the inlet valve housing and opens freely into the collecting trough.
There is, however, scope for simplification of the connections in such an installation.
According to the present invention there is provided a household water-conducting installation comprising a machine operating with water, an inlet hose to conduct water from an inlet valve to an inlet of the machine, an outlet hose to conduct water from an outlet of the machine to a discharge and a leakage water hose surrounding the inlet hose over at least part of the length thereof and arranged to conduct leakage water from the inlet valve to a leakage water collecting trough of the machine, the inlet, outlet and leakage water hoses being combined into a single pipe body.
Through the combination of the inlet hose, leakage water hose and outlet hose in one pipe body, a simple disposition of the hose connections is possible and the inlet valve can, if desired, be pre-assemblable with the pipe body. In addition, stock-keeping by the machine manufacturer is simplified.
Embodiments of the present invention will now be more particularly described with refrence to the accompanying drawings, in which: Figure 1 is a schematic elevation of an installation embodying the invention and comprising a dishwashing machine which is connected by a pipe body to waste water mains and to an inlet valve at a stop cock of water mains; Figure 2 is a cross-section of one form of such pipe body; Figure 3 is a cross-section of another form of such pipe body; and Figure 4 is a sectional view of part of the inlet valve and of the pipe body fastened thereto.
Referring now to the drawings, there is shown in Fig. 1 an installation comprising a dishwashing machine with a rinsing container 1, below which and at the bottom of the machine is a collecting trough 2 for leakage water. The water supply of the dishwashing machine is by way of a water mains with a locally fixed stop cock 3, to which an inlet stub pipe 5 of a housing of an electromagnetic inlet valve 6, which in the illustrated embodiment is controlled by contol equipment (not shown) of the machine, is fastened by means of a coupling nut 4. An inlet hose 8 leads from an outlet stub pipe 7 of the inlet valve housing to a safety valve 9 of the machine and from there by way of a water inlet unit 10 to the rinsing container 1.A leakage water hose 12, enclosing the inlet hose 8, leads from a connecting stub pipe 11 surrounding the outlet stub pipe 7 to the trough 2 and opens freely into the trough.
For control of the valve 6, its magnet coil is connected through an electrical lead 13 with the control equipment of the machine, for example a program control device and/or a valve of the machine, which, for example, stops the water feed to the rinsing container when the water level in the container has reached a safety level.
For the emptying of the rinsing container 1, the dishwashing machine has an emptying pump 14, an outlet hose 15 of which is coupled to a pressure stub pipe of the pump and conducts the used rinsing liquid to a locally fixed waste water mains 16.
The leakage water hose 12, the inlet hose 8 and the outlet hose 15 are combined into a single pipe body 17 and the electrical lead 13 to the inlet valve 6 can be included in this pipe body 17. It is possible to integrate tubes for the individual water conductions in a pipe body profile in such a manner that the tube of the inlet hose extends within the tube of the leakage water hose, while the electrical line either extends in the annular space between the inlet hose and leakage water hose or is embedded directly in the pipe body wall. For the connection of the pipe body 17, the housing of the inlet valve 6 has, part from the outlet stub pipe 7 or the inlet hose 8 and the connecting stub pipe 11 for the leakage water hose, an inlet stub pipe 18 for the outlet hose 15 and a second outlet stub pipe 19 for an outlet hose 20 leading to the waste water mains 16. The housing of the inlet valve 6 includes a passage 21 from the inlet stub pipe 18 to the outlet stub pipe 19.
The unitary pipe body 17, which can be pre-assembled with the inlet valve 6, enables a defined and simple mounting to the locally fixed stop cock 3 and to the waste water mains 16, which is usually present close to the stop cock. The pipe body can be led into the machine housing in a space-saving manner and defined arrangement and is divided only in the machine housing, where the inlet hose 8 is connected to the safety valve 9 of the machine, the outlet hose 15 to the pressure stub pipe of the pump 14 and the electrical lead 13 to the control equipment, while the leakage water hose 12 opens freely into the trough 2.
