Description

Title of the invention: Water treatment system and water treatment apparatus comprising such a treatment system technical field

[0001] The present invention relates to the field of tap water treatment devices that remove pollutants and address taste and odor problems present in tap water by filtration, thereby making it safe and palatable. Pollutants are understood to mean primarily chlorine present in the water, as well as traces of pesticides, pharmaceuticals, or heavy metals, such as lead, which may also be found in tap water. State of the art

[0002] Document US8313644 B2 discloses a water treatment assembly comprising a filter designed to be moved within a carafe filled with water from a high position to a low position to filter the water inside the carafe. The entire treatment assembly is ready to be removed from the carafe for refilling.

[0003] However, the treatment assembly according to US8313644 B2 is complex to handle and if high filtration performance is desired it is then necessary to have a filter with reduced water passage cross-sections and therefore the user exerts a significant effort for a relatively long period to move the filter through the water in the carafe. Summary of the invention

[0004] The present invention aims to remedy these drawbacks.

[0005] The technical problem underlying the invention consists of providing a removable water treatment system, separate from a water container, offering optimized filtration performance and simplified use and maintenance. Filtration is understood to mean any type of method for separating pollutants from water, namely mechanical filtration methods, physical or chemical adsorption methods / processes, or ion exchange processes.

[0006] To this end, the invention relates to a water treatment assembly intended to be received in a removable manner inside a water receiving container of a water treatment device, the treatment assembly comprising a base equipped with a water treatment filter. According to the invention, the base is also equipped with a rotary agitator configured to create a displacement of water through the filter, the filter comprising a housing defining a central cavity for receiving the rotary agitator.

[0007] Thanks to the invention, handling and maintenance of the treatment unit are facilitated since the base includes both the filter and the rotary agitator. This allows the treatment unit to be easily separated from the container and then cleaned and regenerated, for example, by immersing it in boiling water. Furthermore, the rotary agitator, thanks to its positioning relative to the filter, creates water movement through the filter and agitation, which improves filtration performance and provides visual confirmation of water circulation and thus of the operation of the treatment unit.

[0008] According to advantageous but not mandatory aspects of the invention, such a processing set may incorporate one or more of the following features, taken in any technically permissible combination.

[0009] According to an advantageous feature of the invention, the filter comprises activated carbon received in the housing, the housing being suitable for being opened to replace the activated carbon within it.

[0010] Such an arrangement facilitates the replacement of activated carbon when its regeneration capacity, particularly in boiling water, diminishes, thus improving the lifespan of the entire treatment unit simply by changing the adsorbent material. It is no longer necessary to discard the entire treatment unit when filtration performance declines or regeneration becomes ineffective. Furthermore, activated carbon offers good adsorption performance.

[0011] According to an advantageous feature of the invention, the housing comprises: an upper opening at the level of the central cavity, and an internal circumferential wall and an external circumferential wall each provided with at least one through orifice for water circulation through the filter.

[0012] Such an arrangement maximizes the contact between the water and the filter and thus improves filtration performance while offering optimized water circulation through the filter.

[0013] According to an advantageous feature of the invention, the housing comprises a solid upper wall extending between the inner circumferential wall and the outer circumferential wall, the upper wall delimiting the upper opening.

[0014] Such an arrangement ensures radial and optimized water circulation through the filter and therefore good filtration performance.

[0015] According to an advantageous feature of the invention, the rotary agitator is configured to create a displacement of water through the upper opening and then successively through each orifice through the inner circumferential wall and the outer circumferential wall.

[0016] Such an arrangement helps to ensure optimized water circulation through the filter and therefore good filtration performance.

[0017] According to an advantageous feature of the invention, the agitator is configured to create a vortex of water agitation.

[0018] Such an arrangement promotes agitation and circulation of water in order to optimize the performance of the entire treatment system.

[0019] According to an advantageous feature of the invention, the processing assembly includes a gripping rod extending upwards from the base, the gripping rod being suitable for being grasped by a user through a filling opening of the container when the processing assembly is positioned inside the container.

[0020] Such an arrangement makes it easier to handle the entire treatment unit and in particular to remove it from the container when a cleaning or regeneration operation is necessary.

[0021] According to an advantageous feature of the invention, the rotary agitator is rotationally articulated around the gripping rod.

[0022] Such an arrangement facilitates the integration of the rod and the agitator into the processing unit. In addition to its handling function, the rod also guides the rotation of the agitator.

[0023] According to an advantageous feature of the invention, the gripping rod includes at least one axial stop for holding the rotary agitator in a vertical position, the axial stop being positioned opposite an upper portion of the rotary agitator.

[0024] Such an arrangement makes it possible to keep the rotary agitator in position and to prevent its movement in the vertical direction when it is set in rotation.

[0025] According to an advantageous feature of the invention, the gripping rod includes an upper end adapted to interact with an underside of a lid of the container in order to be kept centered in a vertical position.

[0026] Such an arrangement ensures proper positioning of the rod and the treatment assembly in the container.

[0027] According to an advantageous feature of the invention, the rotary agitator is a magnetic stirring element adapted to cooperate with a base for receiving the container and for rotating the magnetic stirring element.

[0028] Such an arrangement simplifies the use and rotation of the rotary agitator.

[0029] According to an advantageous feature of the invention, the base is suitable for being immersed in boiling water to regenerate the filter.

[0030] Such an arrangement makes it possible to obtain a regenerable processing unit and therefore one whose lifespan / use is improved.

[0031] According to an advantageous feature of the invention, the base comprises an outer wall provided with centering elements for the processing assembly in the container, the centering elements being adapted to cooperate with an inner wall of the container, and in that the centering elements are elastically deformable in contact with the inner wall and preferably ensure a removable attachment of the processing assembly to the container.

[0032] Such an arrangement ensures a centered position of the base within the container and allows for translation of the base along the inner wall during its insertion or removal from the container. Furthermore, such an arrangement advantageously ensures that the processing unit is secured to the container through the interaction of the centering elements with the inner wall at the bottom of the container.

[0033] According to an advantageous feature of the invention, the base is suitable for being positioned at the level of a bottom of the container and is suitable for being separated from the container via a vertical upward translation movement through a filling opening of the container.

[0034] Such an arrangement makes it possible to guarantee easy handling of the treatment unit, optimized water circulation in the container, and retention of the treatment unit in the container by contact with the bottom.

[0035] The invention also relates to a water treatment apparatus comprising a water receiving container and a water treatment unit within the container. According to the invention, the treatment unit is as described above.

[0036] According to an advantageous feature of the invention, the apparatus includes a base for receiving the container and for rotating the rotary agitator. Brief description of the figures

[0044] Only the elements necessary for understanding the invention have been shown. To facilitate reading the drawings, the same elements bear the same reference numerals from one figure to another.

[0045] In the following description, the term apparatus is used to designate a water treatment apparatus according to the invention, unless otherwise indicated.

[0046] In the following description, the terms "horizontal", "vertical", "lower", "upper", "top", "bottom"... which may be used, will be used in consideration of the position of the device resting on a horizontal work surface, in a situation of use.

[0047] The terms "external" and "internal," as well as the terms "outside" and "inside," are defined with respect to a central axis of the processing device. Thus, an internal / inside portion / part will be closer to the central axis than an external / outside portion / part.

[0048] The device 10 shown in [Fig.1] is a water treatment device, in particular for tap water.

[0049] The device 10 includes a container 12 capable of holding tap water, a water treatment unit 13 received in the container and a base 14 for receiving the container 12.

[0050] The device 10 also includes a cover 16 for closing a top opening 18 for filling the container 12. The cover 16 is designed to prevent the introduction of impurities into the water contained in said container 12.

[0051] Tap water is introduced into the container 12 through the upper opening 18. The container 12 is, for example, configured to be positioned by a user under the tap with the upper opening 18 opposite a tap water outlet when they wish to fill the container 12.

[0052] In figures 1 to 3, the container 12 comprises a body 20 which is in the form of a cylindrical carafe with a substantially circular cross-section about a vertical axis Z.

[0053] The body 20 is provided at its upper end with a spout 22 for dispensing treated water, facilitating the flow of water when the user pours a drink. Advantageously, the spout 22 is located on the periphery of the upper filling opening 18. The body 20 is preferably made of glass.

[0054] In addition, the container 12 includes a gripping handle 24 fixed to a peripheral edge of the body 20, preferably integral with said peripheral edge, and extending substantially parallel to the vertical axis Z.

[0055] The container 12 advantageously also includes a base 26 which includes a bottom 28 and a contour 30 and is for example suitable for being fitted onto a lower part of the body 20. The contour 30 is advantageously suitable for protecting the body 20 of the container 12, which is preferably made of glass, from possible impacts.

[0056] As can be seen in [Fig. 3], the bottom 28 includes a central opening 32 extending from a lower wall of the bottom to an upper wall of the bottom. Advantageously the central opening 32 has a substantially frustoconical shape and is suitable for cooperating with a projecting portion of the receiving base 14.

[0057] The water treatment assembly 13 is intended to be received / fixed in a removable manner inside the container 12.

[0058] Advantageously and as shown in figures 1 to 3, the water treatment assembly 13 is intended to be positioned against a bottom of the container 12.

[0059] As can be seen in [Fig. 4], the processing set 13 comprises a base 36 equipped with a water treatment filter 38 and a rotary agitator 40 configured to create a movement of water through the filter 38. A filter is understood to mean any system for separating pollutants from water, namely any system implementing mechanical filtration, physical or chemical adsorption or ion exchange processes.

[0060] The processing assembly 13 also includes a gripping rod 42 extending upwards from the base 36 along a central axis XL. The gripping rod 42 is suitable for being grasped by a user through the filling opening 18 when the processing assembly 13 is fixed / received inside the container 12.

[0061] The base 36 is suitable for immersion in boiling water to regenerate the filter 38.

[0062] As seen in [Fig. 4], the base 36 comprises an outer wall equipped with elements centering elements 48 of the processing assembly 13 in the container 12. The centering elements 48 are adapted to cooperate with an internal wall 49 of the container 12 and are preferably elastically deformable in contact with the internal wall 49. Advantageously, the centering elements 48 ensure a removable attachment of the processing assembly 13 to the container 12.

[0063] The centering elements 48 are regularly distributed around the perimeter of the base 36. The base 36 includes, for example, three centering elements 48 distributed every 120° around the circumference of the base 36.

[0064] The base 36 and more generally the processing assembly 13 is adapted to be positioned at the bottom of the container 12 and is adapted to be separated from the container 12 by means of an upward vertical translational movement through the filling opening 18 of the container 12. Similarly, the base 36 and more generally The processing assembly 13 is designed to be positioned in the container 12 via a downward vertical translation movement through the filling opening 18 of the container 12.

[0065] The filter 38 comprises a generally cylindrical housing 52 defining a central cavity 54 for receiving the rotary agitator 40. The filter, and in particular its housing 52, is adapted to contain an adsorbent material such as activated carbon. Alternatively, the housing comprises any other type of adsorbent material or a mixture of adsorbent materials.

[0066] The filter 38 is advantageously an activated carbon filter, and advantageously of granular activated carbon, preferably of size 1 to 10 mm. In this case, the filter then operates by adsorption.

[0067] The housing 52 is suitable for receiving a filter material not shown in the figures containing activated carbon, preferably coconut activated carbon. Indeed, the use of coconut activated carbon has the advantage of being able to regenerate the filter material several times (at least six) by immersion in boiling water to desorb, in particular, all volatile pollutants such as chlorine, for example. Other types of activated carbon are suitable for use, such as coal carbon or bamboo or tree activated carbon such as oak, depending on the pollutants targeted for filtration.

[0068] Alternatively, the filter includes ion exchange resins or ceramics positioned for example in the housing or a mechanical filtration mesh.

[0069] The housing 52 is designed to be opened for replacing the activated carbon inside it. For this purpose, the housing 52 includes, for example, an upper wall 56 forming an access cover inside the housing, allowing access to the activated carbon contained within the housing 52. The cover is movable and / or removable relative to the rest of the housing 52 and is designed to be attached to the rest of the housing by any type of fastener that ensures this movable and / or removable character, such as screws, a hinge system, or a clip system.

[0070] The housing 52 includes a top opening 58 at the level of the central cavity 54. In other words, the top wall 56 of the housing delimits the top opening 58 which is located at the entrance of the central cavity 54.

[0071] The housing 52 includes an internal circumferential wall 60. The internal circumferential wall 60 surrounds the central cavity 54. The internal circumferential wall 60 is opposite the rotary agitator 40.

[0072] The inner circumferential wall 60 includes at least one through-hole 62 for water circulation through the filter. In the example of [Fig. 4], the inner circumferential wall 60 includes six through-holes 62.

[0073] The housing 52 also includes an external circumferential wall 64. The external circumferential wall 64 is intended to be opposite the internal wall 49 of the container when the treatment assembly is received in the container 12. The radial distance between the external circumferential wall 64 and the internal wall 49 of the container 12 is advantageously greater than 5 mm, preferably greater than 10 mm, when the treatment assembly 13 is received in the container 12.

[0074] The outer circumferential wall 64 includes at least one through orifice 66 for water circulation through the filter 38. In the example of [Fig.4], the outer circumferential wall 64 includes six through orifices 66.

[0075] Each through orifice 62, 66 is advantageously partially closed by a grid (not shown) to retain the activated carbon inside the housing 52. The grid has a mesh size smaller than the smallest dimension of the filter material. The grid is micro-perforated and is, for example, made of stainless steel, plastic, or non-woven fabric.

[0076] Each orifice traversing 66 of the external circumferential wall 64 has a cross-section greater than those of the internal circumferential wall 60 with a ratio preferably greater than 1.3.

[0077] In general, the through orifices 66 offer a water passage cross-section greater than the water passage cross-section of the through orifices 62.

[0078] The upper wall 56 is advantageously a solid wall extending between the inner circumferential wall 60 and the outer circumferential wall 64.

[0079] Advantageously, the centering elements 48 are fixed to the external circumferential wall 64.

[0080] The housing 52 also includes a solid bottom 67, also called a solid lower wall, extending between the inner circumferential wall 60 and the outer circumferential wall 64.

[0081] Preferably, the housing 52 is made of stainless steel, other materials remaining conceivable, for example plastics, polymers or mineral materials.

[0082] The rotary agitator 40 is configured to create a displacement of water through the filter 38 and to cause agitation of the water, particularly at the surface. Advantageously, the rotary agitator 40 is configured to create a vortex of water agitation. A vortex is understood to be the appearance of a swirl in the water visible to the user.

[0083] More specifically, the rotary agitator 40 is configured to create a displacement of water through the upper opening 58 and then successively through each orifice 62, 66 of the inner circumferential wall 60 and the outer circumferential wall 64.

[0084] The rotary agitator 40 is articulated in rotation around the gripping rod 42.

[0085] The rotary agitator 40 comprises a lower portion 70 opposite the housing 52 and in particular the internal circumferential wall 60 and an upper portion 72 extending in a vertical direction from the upper wall 56.

[0086] The lower portion 70 is opposite the internal circumferential wall 60.

[0087] The upper portion 72 protrudes from the upper opening 58, in the vertical direction, by at least 5 mm, preferably by at least 10 mm. Such a configuration facilitates the creation of a vortex and the circulation of water through the upper opening 58 and then successively through each orifice 62, 66 of the inner circumferential wall 60 and the outer circumferential wall 64.

[0088] As can be seen in [Fig. 5], the rotary agitator 40 comprises a body 74 of substantially frustoconical shape with the larger base 76 located at the bottom. The body 74 extends along a central axis X2 which is generally coincident with the central axis XI of the rod 42.

[0089] The rotary agitator 40 comprises blades 78 fixed to the body and whose width, measured radially to the vertical axis Z, decreases downwards. Width is understood to mean the dimension of the blades 78 in a radial direction to the axis X2.

[0090] Advantageously, the blades 78 comprise a straight upper edge 80 and / or a straight outer edge 82. Preferably, the upper edge 80 and outer edge 82 are straight and are respectively horizontal and vertical. Advantageously still, the blades 78 are flat and extend in a plane parallel to the central axis X2. The blades also comprise an inner edge 84 in contact with the body 74 and whose shape conforms to that of an outer surface of the body 74 to which each blade is fixed. Advantageously, the blades 78 are one piece with the body 74. Alternatively, the blades 78 are made of a flexible material. By flexible, it is understood that the blades are capable of being elastically deformed, particularly for reasons of demolding during the manufacture of the agitator 40.

[0091] Advantageously and as shown in [Fig.5], the blades 78 extend substantially over the entire height of the body 74. Alternatively, the blades 78 extend at least partially along the lower portion 70 and along the upper portion 72.

[0092] According to another variant, conforming to the second embodiment shown in [Fig. 6], for which the same reference numerals are used as for the first embodiment to designate similar elements, the outer edge 82 is curved and has a point of inflection such that it comprises, along the axis X2, a first concave portion 82A and a second convex portion 82B. In [Fig. 6], the blades 78 have, along the vertical direction, a surface exhibiting a change in concavity and comprising, along the axis X2, a first concave portion 78A and a second convex portion 78B.

[0093] The rotary agitator 40 is a magnetic stirring element suitable for cooperating with the base 14.

[0094] The rotary agitator 40 includes, for example, magnetic inserts 86 in the body 74 near the large base 76. The rotary agitator 40 includes, for example, two magnetic inserts 86 on either side of the central axis X2. The magnetic inserts 86 are, for example, magnets, for example, magnets resistant to a temperature above 100°C. Advantageously, the magnetic inserts 86 comprise several superimposed magnets. The magnetic inserts 86 are advantageously overmolded into the body 74 so that they never come into contact with water.

[0095] When the processing assembly 13 is positioned in the container 12, the gripping rod 42 extends parallel to the vertical axis Z from the base 36 to the vicinity of the upper filling opening 18.

[0096] The gripping rod 42 comprises a lower end 88 fixed to the base 36 and an upper end 90 provided with a gripping member 92. The gripping member 92 is, for example, a gripping ball suitable for being grasped by the user with their fingers when they wish to manipulate the processing assembly 13 and move it relative to the container 12. The gripping ball is preferably made of stainless steel or silicone and is advantageously crimped or fitted onto the rod 42.

[0097] The rod 42 passes through the rotary agitator 40 and also through the central receiving cavity 54 of the rotary agitator. The rod 42 is centered with respect to the base 36 and in particular with respect to the filter 38 and the rotary agitator 40.

[0098] The rod 42 includes a lower portion which forms a rotational guide element for the rotary agitator 40 around which the rotary agitator is articulated via a pivot joint.

[0099] Advantageously, the rod 42 includes at least one axial stop, not visible in the figures, for holding the agitator in a vertical position. The axial stop is, for example, positioned opposite the upper portion 72 of the rotary agitator 40, that is to say, above the rotary agitator 40.

[0100] Advantageously, as seen in [Fig.3], the upper end of the rod 42 and in particular the gripping member 92 is configured to interact with an underside of the lid 16 of the container 12 to be kept centered in a vertical position in the container 12.

[0101] The base 14 is a base for receiving and rotating the magnetic stirring element 40.

[0102] The base 14 includes a motor 96 which is powered by a power source which may be, for example, a rechargeable or disposable battery or even a transformer powered by a power cord with a plug that connects to the mains. The motor 96 drives a magnetic blade 98 in rotation along an axis X3 which coincides with the axis X2 when the container 12 is placed on the base 14.

[0103] The base 14 includes on an upper face 100 receiving the container 12 a projecting portion 102 along the axis X3 suitable for cooperating with the central opening 32 so as to form a means of centering the container 12 on the base 14.

[0104] The magnetic blade 98 is positioned at the protruding portion 102 so as to be as close as possible to the magnetic inserts 86.

[0105] When the container 12 is placed on the base 14, the magnetic attraction force exerted between the rotary agitator 40 and in particular the magnetic inserts 86 and the magnetic blade 98 allows, during the rotation of the magnetic blade 98, to cause the rotation of said rotary agitator 40.

[0106] As seen in [Fig.3], the lid 16 includes a lower face provided with a housing 106 for receiving the gripping member 92. The housing 106 is centered with respect to the lid and ensures centering of the rod 42 and optimized retention of the processing assembly 13 in the container 12.

[0107] The lid 16 is suitable for being removably fixed to the container 12. Advantageously the lid 16 is held fixed to the container via cooperation of form or elastic deformation of a seal at the level of the internal wall 49 surrounding the filling opening 18.

[0108] The operation and handling of the treatment device 10 will be described below in order to fully understand its operation and the technical advantages provided by the treatment unit 13 and more generally the treatment device 10.

[0109] In a first step, the user positions the processing unit 13 inside the container 12. To do this, the user grasps the gripping member 92 and passes the base 36 through the filling opening 18 until it comes into contact with the bottom of the container 12. During this step, the centering elements 48 ensure that the base 36 is centered within the container and moves along the inner wall 49. Advantageously, at the end of this step, the centering elements 48 ensure that the processing unit 13 is secured to the container 12 by means of their interaction with the inner wall 49 at the bottom of the container 12.

[0110] Next, the user fills the container 12 with water and closes it with the lid 16. The gripping member 92 then cooperates with the housing 106 and a centered positioning of the rod 42 in the container 12 is ensured.

[0111] Then, in a subsequent step, the user positions the container 12 on the base 14 and starts the motor 96 to rotate the magnetic blade 98 and consequently the rotary agitator 40. The projecting portion 102 ensures proper centering and secure retention of the container on the base 14.

[0112] The rotary agitator 40 then allows the creation of a vortex promoting the mixing and circulation of the water and causes the water to circulate successively through the upper opening 58, then through the internal through orifices 62 and the external through orifices 64 so that the water rises to the lower part of the container 12 along the internal wall 49.

[0113] This design optimizes water circulation through the filter 38, particularly through the activated carbon, thus enhancing water filtration. Furthermore, the housing's dimensions facilitate water intake into the central cavity 54 and water discharge through the external through-holes 66, thereby optimizing the volume of water circulating through the filter 38 over a given time. Moreover, the centering elements 48 ensure spacing between the through-holes 66 and the inner wall 49, guaranteeing proper water drainage from the filter 38 after it passes through the filter. In addition, the frustoconical shape of the body 74, along with the through-holes 64 and 66, ensures radial water circulation through the filter, resulting in optimal filtration performance. Water flows advantageously several times through filter 38 during the operation of treatment device 10.

[0114] Then, after a predetermined filtration time, for example between 3 and 15 minutes, the motor 96 is automatically switched off, for example, and an indicator light, positioned for example on the base 14, signals that the filtration operation is complete and that the water is ready to be consumed. The water thus circulates several times through the filter 38, and optimized filtration performance is achieved.

[0115] In a subsequent step, once the water in the container 12 has been consumed or after a predetermined number of cycles, i.e., a predetermined number of filtration operations, the user can remove the treatment element 13 for cleaning by handling it via the gripping member 96 and sliding it upwards through the filling opening 18. Advantageously, the user immerses the base in boiling water, for example, monthly to regenerate the filtration capacity of the filter 38, or following the activation of a light indicator on the base after a predetermined number of motor cycles. Furthermore, when the activated carbon received in the housing 52 is more than one year old, the user can replace it by opening the housing and emptying it to add new activated carbon.

[0116] Such an operation / arrangement makes it possible to obtain an improved service life of the treatment unit 13 while guaranteeing its filtration performance. Thus, the use of consumables is reduced compared to existing products and the The lifespan of the treatment device and the entire treatment system is significantly increased.

[0117] Alternatively, the container 12 includes a lower container opening element allowing the treatment assembly 13 to be removed from the container 12 from the bottom rather than via the upper filling opening 18.

[0118] Of course, the present invention is in no way limited to the embodiment described and illustrated, which has been given only by way of example. Modifications remain possible, particularly with regard to the composition of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
