    The invention relates to a shower installation for disposing of a jelly, designed mainly for shower rooms in cultural and sports centers, in the medical sector and in military enterprises. The installation is applicable both in the construction of new buildings, hooks and in the reconstruction of existing showers with minimal costs.
    A well-known shower installation includes a combined bath, a heat exchanger installed therein with inlet and outlet nozzles, the first of which is connected to the cold water supply pipeline, and the second to the heated water removal pipeline connected to the last hot water supply pipeline with a valve installed on it and a mixed feed pipeline with a shower screen placed on it. (See US Patent No. 4291423, A 47 1C 3/22 (4-598), 1981).
    However, the known solution has a disadvantage: the heat exchanger is subjected to the pressure of the water supply network lying in the range of 0.8-1.0 MPa. This means that the heat exchanger must be manufactured in accordance with the conditions of work, which leads to complex structural forms while saving material or to relatively simple forms at high material costs. Further, there is no satisfactory possible leakage in a heat exchanger, which can be caused, for example, by ionization processes. This is particularly true for damage from the side of the pool or the less accessible elements of the heat exchanger.
    The purpose of the invention is to increase the reliability of work and ensure the possibility of controlling its tightness.
    FIG. 1 schematically shows the shower installation; in fig. 2 - housing with valves and an alarm device located in it; FIG. 3 is a section A-A in FIG. 2; in fig. 4 shows a section of B — b in FIG. 3; FIG. - section A-A in FIG. 2 (embodiment of the signal device).
    The shower installation (contains the combined bath 1, the heat exchanger 2 located in this bath, the additional valve b, the valve 5, the signaling device 17 with the optical indicator of water leakage, the shower net 4. The additional valve 6 is mounted in front of the heat exchanger 2 on the pipe 11 of the cold water The pipeline 12 for withdrawing the under-heated water is connected to the pipeline 13 for supplying hot water and to pipe 19 for withdrawing mixed water, n &
    where the shower mesh 4 is located. The water flowing out of the shower mesh, after use, enters the heat transfer surfaces of the heat exchanger 2 and is discharged from the collecting tank 1 to the sewer network.
    The additional valve 6 in the closed state protects the heat exchanger 2 from the effect of the mains pressure from the cold water side and makes it possible to exclude other control valves in the pipes from the heat exchanger 2 to the shower mesh 4. Thus, in any state of the shower installation, the heat exchanger 2 is subjected to
    5 with relatively low pressures, which allows optimal design of the heat exchanger 2 from the point of view of material utilization. So for example when using corrugated hoses from
    Copper as a heat transfer element saves material over 50%.
    In order to determine the softening, heat exchanger 2 is provided with a signal
    5, the device 17, which, together with the valves 5 and 6, is housed in the housing 3. The first embodiment of the signaling device with an optical indicator of water leakage comprises a transparent locking lid 7 fixed on the ledge 10 of the housing 3. Between these elements are stretched thin-walled membranes 8 and 9, for example, from a rubber fabric with a thickness of 0.1-0.2 mm of various colors, the membrane 9 being made 5 with slots 18. The water in the pipe 19 after closing the shower installation deforms the membranes 8 and 9 under the force of gravity to spherical shape The inner surface of the closure cap 7, in which the slots 18 are opened in the membrane 9 and the membrane 8 lying behind it becomes visible. This state continues until the decomposition in the heat exchanger 2 is determined.
    5 or pipelines connected to it.
    Another embodiment of the signal device comprises a gasket 14 of a porous material, preferably plastic or non-ferrous metal, which
    In conjunction with sealing washers 16 tension between the protrusion 10 and the transparent locking lid 7, between the inside surfaces of the locking lid 7 and the gasket 14 of porous material, granular silica 15 is placed, which has the ability to change its color when in contact with water or air. Lowering the water level below the signal level of the signal device 17, for example, in in-decompressions with long interruptions in use
    shower device, leads to a change in the color of silica 15.

    Claims (3)
    [1]
    The timely detection of invisible loosenings and their timely elimination is very important, since the penetration of microscopic particles of dirt that are in the used water and on the walls of the heat exchanger into clean water leads to unhygienic conditions for using a shower installation.
