[0001] DESCRIPTION

[0002] MAGNETIC FILTER

[0003] Technical Field

[0004] The invention relates to a magnetic filter for use as a limescale inhibitor in electrical appliances such as washing machines, dishwashers, combi boilers, geysers, or water heaters or directly in water installations.

[0005] In particular, the invention relates to a magnetic filter which creates a strong magnetic field by placing magnets in the form of cylinders in a plastic sleeve with a screw-shaped outer surface such that the same poles are facing each other, and prevents the limescale formation by allowing the water entering the body made of plastic or brass in which it is placed through the screw form on the outer surface of the sleeve to circulate in a helical shape around these magnets and to be exposed to the strong magnetic field created by the magnets for a long time.

[0006] State of the Art

[0007] The main factors causing limescale formation in water are calcium (Ca2+) and magnesium (Mg2+) ions present in the water. When these positively charged ions combine with carbonate ions (Co32-) in water, they precipitate as calcium carbonate (CaCO3) and magnesium carbonate (MgCO3), leading to the limescale formation. High PH value in water is also a factor that increases limescale formation. Limescale water has a negative impact on electrical appliances such as washing machines, dishwashers and combi boilers, geysers and water heaters, causing malfunctions. If they’re not maintained and limescale inhibitors are not utilized,, these types of electrical appliances become inoperable after prolonged use. This leads to a shortened life of the machine. In limescale water, dirt, limescale and detergent residues accumulate behind the drum, inside the pipes and on the heaters, and the damages of limescale water are also visible on laundry and dishes.

[0008] In current applications, magnetic filters are the leading limescale prevention systems in electrical appliances such as washing machines, dishwashers, and combi boilers, geysers or water heaters. Said magnetic filters change the structure of these ions in thewater and thus the dynamics of their interaction with each other by creating a magnetic field with the magnets therein, transforming them into a structure that will form smaller and less sticky crystal structures instead of forming heavy deposits such as limescale. The effectiveness of magnetic filters in preventing limescale build-up depends on the duration of exposure of the water to the magnetic effect and the strength of the magnetic field in the filter.

[0009] In the present art, magnetic filters are generally divided into filters with a body made of metal and filters with a body made of plastic. The production of filters with plastic bodies is generally carried out by placing a core containing magnets in a plastic injection mold and injecting the plastic raw material melted at high temperature into the mold. Therefore, the high temperature applied during the manufacturing of the body has a negative effect on the magnet performance, which reduces the overall performance of the magnetic filter. In this case, the magnetic field needed for filtering also decreases, and the efficiency of the magnetic filter drops. On the other hand, due to the straight form of the channel through which water passes inside the body, the path and passage time of water inside the body are also short. In addition, existing magnetic filters commonly use magnets in the form of square or rectangular prisms. In square or rectangular prism-shaped magnets, the magnetic field is concentrated at the ends. Due to their position, the water passing through the system runs parallel to the lateral surfaces of the magnets, therefore the effect of this magnetic field on the water at the ends is very small. For this reason, in the state of the art, considering factors such as the water passing through the system being exposed to the magnetic field for only a very short time, the magnetic forces of the magnets within the filter not being utilized effectively due to their shapes and positions, and the temperature generated by the production technique (over injection) reducing the efficiency of the magnets, there is a need for a magnetic filter that eliminates these disadvantages.

[0010] An example of the state of the art in the research conducted in the literature is document numbered TR2021 / 004853. Said document relates to a magnetic limescale inhibitor apparatus. Said apparatus essentially consists of a cabin water passage channel through which water flows, and a cabin containing magnets above and below the cabin water passage channel, an insulation sheath cover attached to the cabin in the direction of the water coming from the mains and containing a sheath cover water passage channel through which the water coming from the mains flows. Since thecross-sectional area of the sheath cover water passage channel in said isolation sheath passage cover is smaller than the cross-sectional area of the cabin water passage channel in the cabin, as a result of the water coming from the mains passing from the sheath cover water passage channel to the cabin water passage area, which has a larger cross-sectional area, without reducing its flow rate but reducing its speed, the water coming from the mains is exposed to a greater magnetic field within the cabin. However, in this application, the exposure time of the water to the magnetic effect is still short, the magnets used have little interaction with each other due to the distance between them, and therefore the magnetic field generated is limited to the strength of the magnets themselves.

[0011] As a result, the existence of the above problems and the inadequacy of the existing solutions have made a development in the relevant technical field necessary.

[0012] Object of the Invention

[0013] The present invention relates to a magnetic filter which eliminates the aforementioned disadvantages and brings new advantages to the relevant technical field.

[0014] The primary object of the invention is to introduce a magnetic filter which prevents the limescale formation by creating a strong magnetic field by placing magnets in the form of cylinders in a plastic sleeve with a screw-shaped outer surface such that the same poles are facing each other, and by allowing the water entering the body made of plastic or brass in which it is placed through the screw form on the outer surface of the sleeve to circulate in a helical shape around the magnets and to be exposed to the strong magnetic field created by the magnets for a long time.

[0015] The object of the invention is to provide a magnetic filter that prevents the magnets from being affected by high temperature due to injection method by placing the magnet group in the body after the production of the body made of plastic by plastic injection method.

[0016] Another object of the invention is to provide a magnetic filter that, thanks to the screw form of the sleeve, enables the mains water flowing in a helical movement around the screw form on the outside of the sleeve to travel approximately 4.5 times the distanceof existing filters within the magnetic field and be exposed to the magnetic effect for approximately 3 times longer.

[0017] Another object of the invention is to introduce a magnetic filter that provides a magnetic field close to twice the level of the magnetic field obtained in the filters of the present art thanks to the magnets placed in the sleeve in the form of a cylinder and stacked on top of each other such that the same poles repel each other.

[0018] Another object of the invention is to introduce a magnetic filter that shapes the magnetic field formed by sheet metal parts placed between magnets, which are stacked on top of each other such that same poles repel each other, into a more linear form, causes it to act perpendicularly on the water passing over it, and increases the total magnetic field as a result of the induction of the sheet metal parts.

[0019] In order to fulfill all objects specified above and those that may be inferred from the detailed description, the invention is a magnetic filter used as a limescale inhibitor in electrical appliances such as washing machines, dishwashers, combi boilers, geysers or water heaters, or directly on water plumbing systems, and relates to comprising:

[0020] a body having a water inlet on one side and a baffled water outlet on the other side, through which mains water is supplied,

[0021] a sleeve located in the body, which guides the water flowing through the body by means of the screw form on its outer surface with a helical movement on its outer surface,

[0053] Detailed Description of the Invention

[0054] In this detailed description, the preferred alternatives of the magnetic filter of the invention are described only for a better understanding of the subject and without any limiting effect.

[0055] Fig. 1 shows the disassembled state of the magnetic filter of the invention. Accordingly, the magnetic filter essentially comprises a body (10) having a water inlet (11) and a water outlet (12) to ensure the flow of water therethrough, a sleeve (20) located in the body (10) and allowing the water passing through the body (10) to follow a long path by circulating it with a helical movement on its outer surface thanks to the screw form (21) in an helical form thereon, a magnet (30) which generates a magnetic field by being placed one on top of the other with the same poles facing each other in the sleeve (20), and reduces the effectiveness of limescale ions in the mains water circulated with a helical movement by means of the screw form (21) on the outer surface of the sleeve (20) over a long distance, a sheet metal part (40) located between said magnets (30) and induced in the magnetic field formed in the magnets (30) to ensure that the magnetic field has a linear structure and increase the total magnetic field, a sleeve cover (60) connected to the sleeve (20) and fixing the magnets (30) in the sleeve (20), a sleeve gasket (50) located within said sleeve cover (60) and providing sealing between the sleeve cover (60) and the sleeve (20), a union (80) located on the water inlet (11) side of the body (10) and enabling the body (10) to be connected to the water mains, a gasket (70) located in the union (80).

[0056] The body (10) forming the main structure of the magnetic filter of the invention is made of plastic or brass material and has a water inlet opening (11) on one side and a water outlet opening (12) on the other side. In the plastic body (10), a union (80) made of metal with a monolithic structure with the body (10) and a threaded inner surface is placed inside the water inlet mouth (11) mentioned in the magnetic filters. Thanks tothe threaded structure of the inner surface of the union (80), the body (10) is connected to the water mains. In the body (10) made of metal, connection of the body (10) to the water mains is achieved by forming screw threads on the inner surface of the water inlet mouth (11) of the body (10) through turning, thereby giving it a self-union structure (80) as shown in Fig. 9

[0057] A gasket (70) is located inside the union (80). The connection to the water mains is sealed by means of the gasket (70) in the union (80).

[0058] Connection threads (121) are also formed on the outer surface of the water outlet mouth (12) in the body (10) and the body (10) is connected from the water outlet mouth (12) to electrical appliances such as dishwashers, washing machines or combi boilers, geysers or water heaters by means of the connection threads (121).

[0059] A sleeve (20) made of plastic is placed inside the body (10) in order to prolong the passage time of the water passing through the body (10) and to ensure longer exposure to the magnetic field. Said sleeve (20) has the screw form (21) that helically wraps around its outer surface as shown in fig. 2. Said screw form (21) enables the water passing through the body (10) to pass through the outer surface of the sleeve (20) by circulating with a helical movement. Thanks to the screw form (21), the passage time of water through the body (10) is extended. The water passing through the body (10) passes through the water passage channels (22) in the baffled structure located on the upper side of the sleeve (20) as shown in fig. 3 and circulates through the screw form (21) on the outer surface of the sleeve (20) with a helical movement. Thanks to the baffled structure of the water passage channels (22), the water passing through the body (10) is ensured to enter the sleeve (20) in a controlled manner.

[0060] A cavity (23) extending along the length of the sleeve (20) was formed on the inner surface of the sleeve (20) as shown in fig. 4a, and cylindrical neodymium magnets (30) were placed in said cavity (23) with the same poles facing each other as shown in fig.

[0061] 4b. Sheet metal parts (40) are placed between said magnets (30) and induced in the magnetic field formed in the magnets (30) to ensure that the magnetic field has a linear structure and increase the total magnetic field.

[0062] Thanks to the cylindrical form of neodymium magnets (30), it is ensured that the magnets (30) exhibit a strong magnetic effect with their high surface area. This isbecause a cylindrical form of the same volume (using the same amount of material) always has a higher surface area (isoperimetric inequality) than a rectangular prism. Considering the homogeneity of the surface magnetic field distributions, the cylindrical magnet (30) always outperforms the rectangular prism magnet. Accordingly, cylindrical magnets (30) were used in the design of the magnetic filter subject to our invention and these magnets were stacked on top of each other in the form of NS-SN such that the same poles repel each other, resulting in an increase in the magnetic field.

[0063] The sleeve (20) has an externally threaded head (24) located on the sleeve (20) so that the sleeve is on the outside of the water passage channels (22). A sleeve cover (60) made of plastic which allows the magnets (30) to be fixed in the cavity (23) of the sleeve (20) is connected to the sleeve (20) by screwing by means of said externally threaded head (24). The sleeve cover (60) shown in fig. 5 has a baffled cover water passage channels (61) on the upper side. An internally threaded housing (62) is located within said sleeve cover (60), which enables the sleeve cover (60) to be connected by screwing onto the externally threaded head (24) on the sleeve (20). The sleeve cover (60) is fixed by screwing on the sleeve (20) as shown in fig. 6. After the fixing process, the cover water passage channels (61) in the sleeve cover (60) and the sleeve water passage channels (22) in the sleeve (20) are positioned coaxially and the uninterrupted passage of the water entering the body (10) to the sleeve (20) is ensured.

[0064] In order to ensure that the magnets (30) located in the cavity (23) in the sleeve (20) remain stationary in the sleeve (20), a clamping pin (63) extending gradually downwards is formed on the lower surface of the sleeve cover (60). Said clamping pin (63) fixes the magnets (30) and sheet metal parts (40) by clamping them into the cavity (23) of the sleeve (20).

[0065] To ensure water sealing between the sleeve cap (60) and the sleeve (20), at least one sleeve gasket (50) is placed inside the sleeve cover (60) as shown in fig. 7, preventing the magnets (30) from coming into contact with water and thus eliminating the risk of corrosion.

[0066] The magnetic filter of the invention shown in fig. 8a and 8b is connected to the water mains via a union (80) and to an electrical appliance such as a dishwasher, washingmachine, boiler, geyser or water heater via the connection threads (121) at the water outlet mouth (12) of the body (10), making it ready for use.

[0067] The working principle of the magnetic filter of the invention is as follows;

[0068] The mains water entering through the water inlet mouth (11) of the body (10) passes through the water passage channels (61) in the sleeve cover (60) and the sleeve water passage channels (22) in the sleeve (20) and circulates through the screw form (21) located outside the sleeve (20) with a spiral movement. In the meantime, the strong magnetic field generated in the neodymium magnets (30) in the sleeve (20) breaks down the limescale ions in the mains water. The mains water, which breaks down limescale ions by circulating around the outer surface of the sleeve (20), exits through the water outlet mouth (12) of the body (10) and enters the machine to which the magnetic filter is connected.
