Description

COMBINED WATER HEATER AND WATER TREATMENT UNIT
Field of the invention
The present invention relates to a combined water heater and water treatment unit, especially intended for a system allowing for purification and recycling of water or separation of water.
Technical Background
There are of course known systems where water heating and treatment are involved, also in systems where purification and recycling of water or separation of water are involved. One example is disclosed in WO2013/095278 which describes a hybrid device for a recirculation shower comprising a filter system with a nano-filter. In WO2013/095278 the treatment is made by filtration and heating is performed in a flow-through water heater.
One main purpose of the present invention is to provide a combined water heater and water treatment unit.
Summary of the invention
The latter stated purpose above is achieved by a combined water heater and water treatment device, said combined water heater and water treatment device comprising a water treatment unit being embedded by a single container of the combined water heater and water treatment device, and said combined water heater and water treatment device also comprising a heater element arranged on the outside of the single container of the combined water heater and water treatment device.
One advantage of the present invention is the compact arrangement. This implies that less space is needed. Furthermore, the use of only a single container and providing the heater on the outside of that single container also provides the advantage of less components needed and creates a simple arrangement in relation to installation and maintenance.

Specific embodiments of the invention
Below specific embodiment of the present invention are disclosed. The actual water treatment unit according to the present invention may vary in terms of technology and function. According to one specific
embodiment, the water treatment unit comprises granulate. These granulates then have a disinfection function which is intended to purify the water.
According to yet another specific embodiment of the present invention, the water treatment unit is a light unit or a radiation unit. In this case, different form of light is the treating medium. The light unit may be a LED unit, UV-LED unit or a conventional UV unit. Furthermore, the wavelength and color of the light should be set to optimize for the treatment of water to purify it from contaminants.
According to one specific embodiment, the light unit is a UV unit, e.g. a UV lamp. In this case the combined water heater and water treatment device according to the present invention preferably also comprises a UV sensor which at least gives an indication of the function of the UV treatment. If a sufficient amount of light reaches the UV sensor, this is an indication that light penetrates the water flow space contained inside the water treatment unit. In the case of a UV lamp, then preferably this is surrounded by a transparent protective cover, e.g. made of a plastic or glass material, such as a quartz glass, to make sure not to contaminate the UV lamp. The space between the quartz glass and the inside wall of the single container holds the water to be treated. The UV light is intended to penetrate all of that space as effectively as possible. Therefore, it is important to make sure that the UV lamp and also the quartz glass is free from contaminants and fouling. Therefore, to enable cleaning of the transparent protective cover is of importance in relation to the present invention. Therefore, according to one specific embodiment of the present invention, the light unit is a UV lamp being surrounded by a transparent protective cover and wherein both the UV lamp and the transparent protective cover are removable from the bottom of the single container. This functionality may be seen in fig. 1 A and 1 B where it can be seen that it is possible to remove the UV lamp and protective cover from the bottom by removing a protective bottom cap. In one example, it may also be possible to remove the UV lamp and protective cover from the top by removing a protective top cap. As illustrated, two caps, one in each end, can be used.
According to another specific embodiment of the present invention there is arranged a cleaning unit in the form of a brush, wiper or scraper rotating around and cleaning the outside of the transparent protective cover.
According to yet another specific embodiment of the present invention, the heater element of the present invention is one coherent single unit. To arrange the heater element as one single unit is of interest to simplify the entire device. As current is intended to be fed to the heater element it is of course of interest only to use one electric connection instead of multiple.
According to yet another specific embodiment of the present invention, the heater element is embedded in isolation. The isolation may comprise different material and have different size etc. As an example, a size of around 10 mm may be sufficient to embed the heater element in an effective way.
According to yet another specific embodiment of the present invention, the heater element is a film attached to a portion of the outside surface of the single container. The use of one coherent single heater film is preferable to provide an effective and compact device according to the present invention. The present invention also has other possible features. According to one specific embodiment, the combined water heater and water treatment device has one or more electricity safety functions. Possible alternatives are e.g. earthing of the container cover and a thermostat connected to the container cover, where the latter stops the power supply during a short circuit or overheating.
Moreover, according to another specific embodiment of the present invention both an inflow and an outflow of the combined water heater and water treatment device are arranged on the side of the device. This decreases the needed height when installing the device, which is beneficial. This is further seen for example in fig. 2 of the drawings.
The above disclosed features are also som other differences between the present invention when being compared to CN104556271 A.
The present invention also refers to a system allowing for purification and recycling of water or separation of water, comprising a combined water heater and water treatment device according to the present invention.
According to one specific embodiment of the present invention, the combined heater and water treatment unit is arranged subsequent a water filtration unit in terms of process flow in such a system allowing for purification and recycling of water or separation of water.

The vertical positioning of the filtration unit and combined heater and water treatment unit in that order has several advantages. First of all, this arrangement enables back-flushing of the filter unit, and also the combined heater and water treatment unit, by draining water in the system from the top to the bottom by using gravity. Secondly, such a draining of the filtration unit also implies that the draining is performed from a cleaner part of the filtration unit to a dirtier side thereof, which also is beneficial. Repeated filling and draining enables a cleaning cycle which, if needed, can be made more potent using a chemical solution. Furthermore, when filling the system from bottom to top, then air in the system is transported the same direction. As such, there is no need to ventilate the system and there is minimal risk for air pockets.
According to yet another specific embodiment of the present invention, there is disclosed a method for allowing for purification and recycling of water or separation of water in a system intended therefore, said method
