In one of the preferred embodiments of the zone water-treatment device 1 according to the invention, the zone water-treatment cartridge 3 is allowed to rotate continually in the head 2 of the device 1 between the first and the second limit position, as described above. In other words, in such an embodiment, the zone water-treatment cartridge 3 is allowed to be set in each possible rotational position relative to the head 2 of the device 1 between the first and the second limit position. In another preferred embodiment of the zone water-treatment device 1 according to the invention, the zone water-treatment cartridge 3 is allowed to rotate discretely in the head 2 of the device 1 between the first and the second limit position. In other words, in such an embodiment, the zone water-treatment cartridge 3 is allowed to be set in specific rotational positions relative to the head 2 of the device 1 between the first and the second limit position. The discrete positions for the zone water-treatment cartridge are selected as needed depending, for example, on the quality of the water from the water-supply network to be treated and/or the type of the zone water-treatment cartridge 3 used. The discrete positions of the zone water-treatment cartridge 3 in the head 2 of the water-treatment device are provided, for example, by means of a ratchet mechanism arranged in the head 2 of the zone water-treatment device, which cooperates with the determining elements in the form of notches or cavities arranged correspondingly on the zone water-treatment cartridge 3, for example near or on the neck 5 of the body of the cartridge 3.
In a preferred embodiment of the invention comprising a venting system, as described above, the zone water-treatment device 1 system is vented by pressing the vent button. Venting the zone water-treatment device 1 system can be performed at any moment following installation of the zone water-treatment cartridge and as many times as required. Venting the zone water-treatment device 1 system can be performed immediately after installation of the zone water-treatment cartridge 3 in the zone water-treatment device 1 after setting the cartridge 3 in the device 1 or at any moment during the operation of the device 1.
When it is necessary to uninstall or replace the zone water-treatment cartridge 3, for example, as a result of a damage, loss of its water-treatment properties, one should activate the releasing means 28, for example, as in one of the preferred embodiments, as shown in
In a preferred embodiment of the head 2 of the water-treatment device 1 comprising the terminating means 23, 24, during removal of the zone water-treatment cartridge 3 from the head 2 of the zone water-treatment device 1, the terminating means 23 are activated of the port 12 of the head 2 of the zone water-treatment device 1, terminating thus the fluid communication for feeding water from the port 12 to the seat 4 of the device 1 and the terminating means 24 are activated of the port 13 of the head 2 of the zone water-treatment device 1, terminating thus the fluid communication for water which could return to the seat 4 of the head 2 of the zone water-treatment device 1. This prevents the flooding the environment in which the zone water-treatment device 1 is situated while removing or after removing the zone water-treatment cartridge 3 from the device 1, that is, when the zone water-treatment cartridge 3 slides out of the seat 4 or is no longer in it.
After removing the zone water-treatment cartridge 3, a new zone water-treatment cartridge 3 or a reconditioned zone water-treatment cartridge 3 can be installed, as described above.
Therefore, the zone water-treatment cartridge 3 according to the invention, the head 2 according to the invention for the zone water-treatment device 1 according to the invention and the zone water-treatment device 1 according to the invention provide technical solutions, i.e., the cartridge, the head and the device, as described above, wherein by rotation of the zone water-treatment cartridge in the head of the zone water-treatment device the flow of water through the particular zones of the zone water-treatment cartridge is controlled quickly, easily and enjoyably. The zone water-treatment device comprises a remarkably simple and reliable setting or controlling system for establishing a flow of water through the particular zones of the cartridge, particularly useful in a confined space and without having to use additional tools, such as screwdriver, a hex key, etc.
Based on the above disclosure, it will be clear to a specialist that certain technical aspects can be realized in many different ways. For example, the cylindrical part 15 may be integrated with the cap 16 to form a uniform body of the zone water-treatment cartridge 3. Moreover, the zone water-treatment device 1 can comprise more than one head 2. Depending on the needs, the zone water-treatment device 1 can comprise two, three or more heads 2 in which the same or different zone water-treatment cartridges 3 can be installed, that is, cartridges 3 performing the same or different zone water treatments, as described above in detail. A specialist will be aware that these two or more heads 2 may be connected in series to perform a subsequent treatment or in parallel to perform a water co-treatment.
The invention is described above with respect to preferred embodiments by way of example only. Based on the above disclosure, a specialist will recognize that modifications, variants or equivalents are possible falling within the spirit and inventive intention of the present invention, and without exceeding the scope of the attached claims.
The features indicated in the embodiments of the invention described above, especially in the preferred embodiments of the present invention, can be combined or replaced to any extent and in any configurations, whereby all new possible combinations or configurations are deemed fully disclosed in the description of the present invention.
