The present invention is related in general to water treatment, in particular domestic treatment of tap water. More specifically, the present invention is related to a water-treatment cartridge for a water-treatment device. Furthermore, the present invention is related to a head of the water-treatment device. The present invention is related also to a water-treatment device comprising such a cartridge and such a head.
There are known water-treatment devices, especially for tap water, comprising a head with a water-treatment cartridge arranged therein. Such a water-treatment cartridge is also referred to as a water-treatment insert. A water-treatment cartridge of such solutions typically constitutes an exchangeable water-treatment cartridge. The exchangeable water-treatment cartridge usually constitutes a filtering cartridge. In such a case, the exchangeable water-treatment cartridge comprises an activated carbon bed on which water filtration and absorption of undesirable chemical compounds present in the water to be treated, especially in raw tap water, takes place. The water-treatment cartridge may also constitute a cartridge for adjusting water hardness, a cartridge for adjusting water pH, a cartridge for enriching water with a desired substance, for example, desired ions, such as calcium, magnesium ions, and a cartridge for biological treatment. In such a case, the exchangeable water-treatment cartridge comprises a bed for adjusting water hardness, a bed for adjusting water pH, a bed for enriching water with a desired substance, and a bed for biological treatment, respectively In some available domestic water-treatment devices, the water-treatment cartridge constitutes an exchangeable zonal water-treatment cartridge. Such a zonal water-treatment cartridge usually comprises two zones, typically comprising different water-treatment beds, wherein in the first zone, first water treatment on the first bed takes place, and in the second zone, second water treatment on the second bed takes place. Most frequently, such a zonal water-treatment cartridge comprises a cartridge which filters and softens tap water and changes its pH. The water-treatment cartridge wears out with time. That is, the filtering cartridge gets clogged, the cartridge for adjusting water pH loses its pH adjustment properties, the cartridge for enriching water wears out and no longer introduces the desired substances into water, and the cartridge for biological treatment no longer improves the biological purity of the water treated. If this is the case, the water-treatment cartridge needs replacing.
In the known domestic devices for tap water treatment, the exchangeable water-treatment cartridge is mounted in the head of a water-treatment device by means of methods that are simple and untroublesome for the user. Most frequently, the exchangeable water-treatment cartridge is click-fitted in the head of a water-treatment device. In such solutions, the exchangeable cartridge typically comprises a protrusion, which engages a latch system contained in the head of a water treatment device. The latch system in the head is connected to a button which, when pressed, releases the exchangeable water-treatment cartridge from the head of a water-treatment device. Following removing the previous, usually worn water-treatment cartridge, typically a new water-treatment cartridge is placed in the head. When mounted, the water-treatment cartridge is placed in the head by pressing it until a characteristic “click” sound is heard, said sound being produced as the latch system of the head of a water-treatment device latches on the protrusion of the water-treatment cartridge. After the “click” sound is heard, which means that the water-treatment cartridge has been fitted in the head of the water-treatment device, the device is substantially ready for use.
Although the click-fitting of the water-treatment cartridge in the head of a water-treatment device, as described above for devices known from prior art, is simple and untroublesome for the user, it does pose certain problems. One of them is that there is a play between the water-treatment cartridge and the head of a water-treatment device, which may result in imprecise fitting of the water-treatment cartridge in the head of a water-treatment device. Imprecise fitting of an exchangeable water-treatment cartridge in the head of a water-treatment device may result in an imprecise flow connection between the water-treatment cartridge and the head of a water-treatment device and, consequently, to a disruption of the flow of water to be treated into the water-treatment cartridge and/or a disruption of the flow of treated water from the water-treatment cartridge into the head of the water-treatment device and further outside said water-treatment device. Another problem is that while using a water-treatment device, the water-treatment cartridge may get jammed in the water-treatment head, thus hampering removal of the water-treatment cartridge from the head of the water-treatment device. Jamming of the cartridge in the head may result, for example, but not limited to, by precipitation of sediment from water, especially from raw tap water of high hardness, within the limits of the connection between the water-treatment cartridge and the water-treatment head, causing the cartridge to get jammed in the head of a water-treatment device. Another factor which may hamper or even prevent removal of the water-treatment cartridge is the jamming of the rubber sealings, usually in the form of O-rings arranged on the neck of the water-treatment cartridge, providing sealing between the water-treatment cartridge and the head. The jamming of the rubber sealings results from the sticking of the water-treatment cartridge to the head of a water-treatment device, which head and cartridge are typically made of a plastic. The jamming of the water-treatment cartridge in the head of a water-treatment device is the greater the longer the water-treatment cartridge operates in the head of a water-treatment device and/or the greater the sealing tension the O-rings of the sealing are subjected to in the head. Therefore, when removing the water-treatment cartridge from the head of a water-treatment device, it is necessary to overcome the jamming by tearing the sealing off from at least the surface of the head of the water-treatment device. The foregoing problems are particularly burdensome when a water-treatment device is installed within a confined space, such as especially the space under a sink, wherein such water-treatment devices are typically installed.
Therefore, there is a demand for a water-treatment device, wherein a precise positioning of an exchangeable water-treatment cartridge in the head of the water-treatment device is provided, such device facilitating removal of such exchangeable water-treatment cartridge from the head of the water-treatment device, especially after the device has been used for an extended period of time and subjected to poor quality raw water to be treated, such device being simple and ensuring quick exchange of said exchangeable water-treatment cartridge in the water-treatment device.
Therefore, in the first aspect of the present invention a water-treatment cartridge for a water-treatment device is provided, as specified in the independent claim 1.
The preferred embodiments of the water-treatment cartridges are specified in the dependent claims 2 to 8.
In another aspect of the present invention, a head for a water-treatment device is provided, as specified in the independent claim 9.

In another aspect of the present invention, a water-treatment device is provided, as specified in the independent claim 16.
The preferred embodiments of the water-treatment device are specified in the dependent claims 17 to 23.
Therefore, the technical solutions according to the above-mentioned aspects of the present invention provide a water-treatment cartridge, a head of a water-treatment device and a water-treatment device comprising said head and said cartridge, wherein a simple design allowing easy and quick mounting of the water-treatment cartridge in the head of the water-treatment device while ensuring more precise positioning of said cartridge in said head of the water-treatment device is provided. Furthermore, the technical solution according to the above-mentioned aspects of the present invention allows easier removal of the water-treatment cartridge from the head of a water-treatment device, especially when the device is installed in a space with a limited access, such as, for example, a sink cabinet.
The invention is now described in more detail with reference to the figures of the drawing, wherein:
The present invention provides a water-treatment cartridge 1 for a water treatment device 100. As shown in
