Description

Technical Field

[0001] This invention relates to the field of tap water treatment equipment, which can treat contaminants, taste, and odor problems in tap water through filtration and agitation, making it drinkable and palatable. The contaminants mainly refer to chlorine present in the water, as well as trace amounts of pesticides, pharmaceuticals, or heavy metals (such as lead) that may also be present in tap water. Background Technology

[0002] Document EP1031539 A1 discloses a water treatment device including a water container containing a treatment assembly, the treatment assembly including a water treatment filter and a rotary agitator received within a central cavity defined by the filter.

[0003] However, the processing components according to EP1031539 A1 cannot achieve optimal filtration performance. Summary of the Invention

[0004] The present invention aims to overcome these shortcomings.

[0005] The fundamental technical problem of this invention lies in providing a water treatment component that can deliver optimal filtration performance in a short time. Filtration refers to any type of method for separating contaminants from water, namely mechanical filtration, physical or chemical adsorption methods / processes, or ion exchange processes.

[0006] Therefore, the present invention relates to a water treatment assembly housed within a water container of a water treatment device. The assembly includes a base equipped with a water treatment filter and a rotary agitator configured to generate movement of water through the filter. The filter includes a generally cylindrical housing defining a central cavity receiving the rotary agitator. According to the invention, the rotary agitator includes a lower portion opposite the housing and an upper portion extending vertically beyond the upper wall of the housing.

[0007] Thanks to this invention, the filtration performance of the processing unit is optimized because the rotary agitator's design facilitates water circulation through the filter and achieves optimal water agitation. In fact, the upper portion of the rotary agitator extends beyond the housing, which facilitates water circulation into the central cavity and surface agitation, advantageously generating eddies, while the lower portion guides water through the filter to improve filtration performance. Furthermore, the rotary agitator's architecture allows the user to visually confirm that water is circulating and filtration is in progress, as the user can observe the surface agitation and the generation of eddies.

[0008] According to an advantageous but non-mandatory aspect of the invention, such a processing component includes one or more of the following features, which can be combined in any technically permissible combination.

[0009] According to an advantageous feature of the invention, the upper wall of the housing defines an upper opening at the central cavity, and the upper portion extends vertically beyond the upper opening by at least 5 mm, preferably at least 10 mm.

[0010] This arrangement optimizes the agitation of the water surface and effectively generates water turbulence.

[0011] According to an advantageous feature of the invention, the rotary stirrer comprises a generally truncated cone-shaped body, with its largest bottom located at the bottom.

[0012] This arrangement optimizes the guidance of water toward and through the filter, thereby improving filtration performance. Water thus passes through the filter in a radial direction relative to the vertical.

[0013] According to an advantageous feature of the invention, the rotary stirrer includes blades fixed to the body, the width of which decreases downwards.

[0014] The shape of the blades optimizes water agitation and directs water toward the filter.

[0015] According to an advantageous feature of the invention, the blade includes a straight upper edge and / or a straight outer edge.

[0016] This arrangement also optimizes water agitation and directs water toward the filter.

[0017] According to an advantageous feature of the invention, the blade is flat and extends in a vertical direction.

[0018] This arrangement improves the guidance of water through the filter.

[0019] According to an advantageous feature of the invention, the blade has a surface exhibiting a concave variation along the vertical direction, and includes a first concave portion and a second convex portion along the vertical direction.

[0020] This arrangement provides excellent water agitation performance.

[0021] According to an advantageous feature of the invention, the filter includes activated carbon contained in the housing, the housing being adapted to be opened to replace the activated carbon inside.

[0022] This arrangement facilitates the replacement of activated carbon when its regeneration capacity (especially in boiling water) decreases, thus extending the lifespan of the treatment unit simply by replacing the adsorbent material. When filtration performance deteriorates or regeneration becomes ineffective, the entire treatment unit no longer needs to be discarded. Furthermore, activated carbon exhibits excellent adsorption properties.

[0023] According to an advantageous feature of the invention, the housing includes: an upper opening at the central cavity, and an inner peripheral wall and an outer peripheral wall, each of the inner and outer peripheral walls being provided with at least one through hole for water to flow through the filter.

[0024] This arrangement maximizes the contact between water and the filter, thereby improving filtration performance while providing optimal water circulation through the filter.

[0025] According to an advantageous feature of the invention, the upper wall of the housing is solid and extends between the inner peripheral wall and the outer peripheral wall, the upper wall defining the upper opening.

[0026] This arrangement ensures that water circulates radially and optimally through the filter, resulting in good filtration performance.

[0027] According to an advantageous feature of the invention, the rotary agitator is configured to generate movement of water through the upper opening and then successively through each through-hole of the inner and outer peripheral walls.

[0028] This arrangement also helps ensure optimal water circulation through the filter, resulting in good filtration performance.

[0029] According to an advantageous feature of the invention, the inner peripheral wall is opposite to the rotary stirrer, and the outer peripheral wall is positioned opposite to the inner wall of the container, wherein when the processing assembly is housed inside the container, the radial distance between the outer peripheral wall and the inner wall of the container is greater than 5 mm, preferably greater than 10 mm.

[0030] This arrangement facilitates water circulation through the filter, particularly at the outer peripheral wall, without creating flow disturbances that would degrade the filtration performance of the treatment components. In fact, the distance between the outer peripheral wall and the inner wall of the container allows water at the filter outlet to rise along the inner wall without obstruction.

[0031] According to an advantageous feature of the invention, the cross-section of each through hole in the outer peripheral wall is larger than the cross-section of the through hole in the inner peripheral wall, preferably the ratio is greater than 1.3.

[0032] This arrangement helps to achieve optimal water circulation through the filter, resulting in good filtration performance.

[0033] Advantageously, the base includes a wall equipped with a centering element for aligning the processing components in the water container.

[0034] This arrangement facilitates the positioning of components within the container.

[0035] According to an advantageous feature of the invention, the rotary stirrer is a magnetic stirrer adapted to cooperate with the receiving base of the container and to rotate the magnetic stirrer.

[0036] This arrangement simplifies the use and rotation of the rotary mixer.

[0037] According to an advantageous feature of the invention, the base is adapted to be immersed in boiling water to regenerate the filter.

[0038] This arrangement makes the processing components recyclable, thus improving their lifespan / usage time.

[0039] The present invention also relates to a water treatment apparatus comprising a water-containing container and a water treatment assembly inside the container. According to the present invention, the treatment assembly is the one described above.

[0040] According to an advantageous feature of the invention, the device includes a base for receiving a container and rotating a rotary stirrer. Attached Figure Description

Detailed Implementation

[0042] The accompanying drawings show only the elements necessary for understanding the invention. For ease of reading, the same elements are referred to using the same reference numerals across the figures.

[0043] In the following sections of this specification, the term "equipment" is used to refer to the water treatment equipment according to the invention, unless otherwise indicated.

[0044] In the following sections of this manual, terms such as “horizontal,” “vertical,” “low,” “up,” “high,” and “low” may be used, taking into account the usage position of the equipment when placed on a horizontal workbench.

[0045] The terms "outer" and "inner," as well as "external" and "internal," are defined relative to the central axis of the water treatment equipment. Therefore, the internal parts / sections are closer to the central axis than the external parts / sections.

[0046] Figure 1 The device 10 shown is a water treatment device, particularly for tap water.

[0047] The device 10 includes a container 12 capable of holding tap water, a water treatment component 13 housed in the container, and a base 14 for receiving the container 12.

[0048] The device 10 also includes a cover 16 for closing the filling opening 18 of the container 12. The cover 16 is adapted to prevent impurities from being introduced into the water contained in the container 12.

[0049] Tap water is introduced into container 12 through upper opening 18. For example, when a user wishes to fill container 12, container 12 is configured so that the user places it under the faucet with upper opening 18 opposite the faucet spout.

[0050] exist Figures 1 to 3 In the container 12, there is a main body 20, which is in the form of a cylindrical kettle, and its cross-section is approximately circular on the vertical axis Z.

[0051] The main body 20 has a water-treatment spout 22 at its upper end to facilitate water flow when the user drinks. Advantageously, the spout 22 is located around the periphery of the filling opening 18. The main body 20 is preferably made of glass.

[0052] In addition, the container 12 includes a handle 24, which is fixed to the peripheral edge of the body 20, preferably integral with the peripheral edge, and extends substantially parallel to the vertical axis Z.

[0053] The container 12 advantageously also includes a seat cover 26, which comprises a bottom 28 and a skirt 30, and is adapted, for example, to fit over the lower part of the body 20. The skirt 30 is advantageously adapted to protect the body 20 of the container 12 (which is preferably made of glass) from possible impacts.

[0054] like Figure 3 As shown, the bottom 28 includes a central opening 32 that extends from the lower wall of the bottom to the upper wall of the bottom. Advantageously, the central opening 32 is generally frustoconical and adapted to cooperate with the protrusion of the receiving base 14.

[0055] The water treatment component 13 is housed / secured inside the container 12 in a detachable manner.

[0056] Advantageously, such as Figures 1 to 3 As shown, the water treatment component 13 is positioned against the bottom of the container 12.

[0057] like Figure 4 As shown, the treatment assembly 13 includes a base 36 equipped with a water treatment filter 38 and a rotary agitator 40 configured to generate movement of water through the filter 38. A filter is any system that separates contaminants from water, i.e., any system that implements mechanical filtration, physical or chemical adsorption, or ion exchange processes.

[0058] The processing assembly 13 also includes a gripping lever 42 that extends upward from the base 36 along the central axis X1. When the processing assembly 13 is secured / accommodated inside the container 12, the gripping lever 42 is adapted to be gripped by a user through the filling opening 18.

[0059] The base 36 is adapted to be immersed in boiling water to regenerate the filter 38.

[0060] like Figure 4 As shown, the base 36 includes an outer wall equipped with a centering element 48 for aligning the processing assembly 13 within the container 12. The centering element 48 is adapted to cooperate with the inner wall 49 of the container 12 and is preferably elastically deformable upon contact with the inner wall 49. Advantageously, the centering element 48 detachably secures the processing assembly 13 to the container 12.

[0061] Centering elements 48 are regularly distributed on the periphery of the base 36. The base 36 includes, for example, three centering elements 48 distributed on the circumference of the base 36 at 120° intervals from each other.

[0062] The base 36 and more generally the processing assembly 13 are adapted to be positioned at the bottom of the container 12 and to be separated from the container 12 by 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 are adapted to be positioned in the container 12 by a downward vertical translational movement through the filling opening 18 of the container 12.

[0063] The filter 38 includes a generally cylindrical housing 52 that defines a central cavity 54 for receiving a rotary stirrer 40. The filter, particularly its housing 52, is adapted to contain an adsorbent material, such as activated carbon. As a variation, the housing may contain any other type of adsorbent material or a mixture of adsorbent materials.

[0064] Filter 38 is advantageously an activated carbon filter, and more advantageously a granular activated carbon filter, preferably with a particle size of 1 to 10 mm. In this case, the filter operates by adsorption.

[0065] The housing 52 is adapted to contain filter material (not shown in the figure), which comprises activated carbon, preferably coconut shell activated carbon. In fact, using coconut shell activated carbon has the ability to regenerate the filter material multiple times (at least six times) by immersion in boiling water to desorb, in particular, all volatile pollutants (e.g., chlorine). Other activated carbons are also suitable for use, such as coal-based activated carbon, bamboo activated carbon, or wood-based activated carbon (e.g., oak), depending on the target pollutant to be filtered.

[0066] As a variation, the filter includes ion exchange resin or ceramic, for example, positioned in a housing, or includes a mechanical filter screen.

[0067] The housing 52 is adapted to be opened to replace the activated carbon inside. For this purpose, the housing 52 includes, for example, an upper wall 56 that forms a cover leading into the interior of 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 adapted to be secured to the rest of the housing 52 by any means of fastening that ensures this movable and / or removable characteristic (e.g., screws, hinge systems, or snap-fit ​​systems).

[0068] The housing 52 includes an upper opening 58 in the central cavity 54. In other words, the upper wall 56 of the housing 52 defines the upper opening 58, which is located at the entrance of the central cavity 54.

[0069] The shell 52 includes an inner peripheral wall 60. The inner peripheral wall 60 surrounds the central cavity 54. The inner peripheral wall 60 is opposite to the rotary stirrer 40.

[0070] The inner peripheral wall 60 includes at least one through-hole 62 for water to flow through the filter. Figure 4 In the example, the inner peripheral wall 60 includes six through holes 62.

[0071] The housing 52 also includes an outer peripheral wall 64. When the processing assembly is housed in the container 12, the outer peripheral wall 64 is positioned opposite the inner wall 49 of the container 12. The radial distance between the outer peripheral wall 64 and the inner wall 49 of the container 12 is advantageously greater than 5 mm, preferably greater than 10 mm.

[0072] The outer peripheral wall 64 includes at least one through-hole 66 for water to flow through the filter 38. Figure 4 In the example, the outer peripheral wall 64 includes six through holes 66.

[0073] Each through-hole 62, 66 is advantageously partially closed by a grid (not shown) to retain activated carbon inside the housing 52. The mesh size of the grid is smaller than the minimum size of the filter material. The grid is microporous and is made, for example, of stainless steel, plastic, or nonwoven fabric.

[0074] The cross-section of each through hole 66 in the outer peripheral wall 64 is larger than the cross-section of the through hole 62 in the inner peripheral wall 60, preferably the ratio is greater than 1.3.

[0075] Generally speaking, the cross-sectional area through which water passes is greater than that through the cross-sectional area through the through hole 66.

[0076] The upper wall 56 is advantageously a solid wall, extending between the inner peripheral wall 60 and the outer peripheral wall 64.

[0077] Advantageously, the centering element 48 is fixed on the outer peripheral wall 64.

[0078] The housing 52 also includes a solid bottom 67, also known as a solid lower wall, extending between the inner peripheral wall 60 and the outer peripheral wall 64.

[0079] Preferably, the housing 52 is made of stainless steel, but other materials are also possible, such as plastics, polymers or minerals.

[0080] The rotary agitator 40 is configured to generate movement of water through the filter 38 and cause agitation of the water, particularly the surface. Advantageously, the rotary agitator 40 is configured to generate water eddies. An eddy refers to a vortex in the water that is visible to the user.

[0081] More precisely, the rotary agitator 40 is configured to generate movement of water through the upper opening 58 and then successively through each of the through holes 62, 66 of the inner peripheral wall 60 and the outer peripheral wall 64.

[0082] The rotary mixer 40 is rotatably hinged around the gripping rod 42.

[0083] The rotary stirrer 40 includes a lower portion 70 opposite to the housing 52, particularly opposite to the inner peripheral wall 60, and an upper portion 72 extending vertically beyond the upper wall 56.

[0084] The lower part 70 is opposite to the inner peripheral wall 60.

[0085] The upper portion 72 extends vertically beyond the upper opening 58 by at least 5 mm, preferably at least 10 mm. This configuration facilitates the generation of eddies and the circulation of water through the upper opening 58 and then successively through each through hole 62, 66 of the inner peripheral wall 60 and the outer peripheral wall 64.

[0086] like Figure 5 As shown, the rotary stirrer 40 includes a generally frustoconical body 74 with its largest bottom 76 located at the bottom. The body 74 extends along a central axis X2, which generally coincides with the central axis X1 of the rod 42.

[0087] The rotary stirrer 40 includes blades 78 fixed to the body 74, the width of which (measured radially in the direction of the vertical axis Z) decreases downwards. The width refers to the dimension of the blades 78 in the radial direction of the axis X2.

[0088] Advantageously, the blade 78 includes a straight upper edge 80 and / or a straight outer edge 82. Preferably, the upper edge 80 and the outer edge 82 are straight and extend horizontally and vertically, respectively. More advantageously, the blade 78 is flat and extends along a plane parallel to the central axis X2. The blade also includes an inner edge 84 that contacts the body 74, the shape of which conforms to the outer surface shape of the body 74 to which the blade is fixed. Advantageously, the blade 78 is integrally formed with the body 74. As a variation, the blade 78 is made of a flexible material. Flexibility refers to the blade's ability to deform elastically, particularly for ease of demolding during the manufacture of the stirrer 40.

[0089] Advantageously, such as Figure 5 As shown, the blade 78 extends approximately over the entire height of the body 74. As a variation, the blade 78 extends at least partially along the lower portion 70 and along the upper portion 72.

[0090] According to another variant, it conforms to Figure 6 The second embodiment shown (where the same reference numerals denote elements similar to those in the first embodiment) has an outer edge 82 that is curved and has an inflection point, such that it includes a first recess and a second convex portion along the axis X2. Figure 6 In the middle, the blade 78 has a surface with a concave change along the vertical direction, and includes a first concave portion 78A and a second convex portion 78B along the axis X2.

[0091] The rotary stirrer 40 is a magnetic stirrer that is adapted to work in conjunction with the base 14.

[0092] The rotary stirrer 40 includes, for example, a magnetic insert 86 located near the maximum bottom 76 in the body 74. The rotary stirrer 40 includes, for example, two magnetic inserts 86, located on either side of the central axis X2. The magnetic inserts 86 are, for example, magnets, such as magnets resistant to temperatures above 100°C. Advantageously, the magnetic inserts 86 comprise a plurality of stacked magnets. The magnetic inserts 86 are advantageously overmolded within the body 74 such that they never come into contact with water.

[0093] When the processing component 13 is positioned in the container 12, the gripping bar 42 extends from the base 36 parallel to the vertical axis Z until it approaches the filling opening 18.

[0094] The grip bar 42 includes a lower end 88 fixed to the base 36 and an upper end 90 equipped with a gripper 92. The gripper 92 is, for example, a grip ball, adapted to be gripped by the user's fingers when the user wishes to operate the handling component 13 and move it relative to the container 12. The grip ball is preferably made of stainless steel or silicone and is advantageously pressed or fitted onto the bar 42.

[0095] Rod 42 passes through rotary agitator 40 and also through the central receiving cavity 54 of rotary agitator. Rod 42 is centered relative to base 36, and in particular relative to filter 38 and rotary agitator 40.

[0096] The rod 42 includes a lower portion that forms a rotation guide for the rotary stirrer 40, which is pivotally connected and rotatably hinged around the guide.

[0097] Advantageously, the rod 42 includes at least one axial stop (not shown) for holding the agitator in its vertical position. The axial stop is positioned, for example, opposite to the upper portion 72 of the rotary agitator 40, i.e., above the rotary agitator 40.

[0098] Advantageously, such as Figure 3 As shown, the upper end of the rod 42, particularly the gripper 92, is configured to interact with the lower surface of the lid 16 of the container 12 to be held in a vertically centered position within the container 12.

[0099] The base 14 is a base that receives the base and rotates the magnetic stirrer 40.

[0100] The base 14 includes a motor 96 powered by an energy source, such as a rechargeable or disposable battery, or a transformer connected to a power source via a power cord equipped with a plug. The motor 96 causes the magnetic blades 98 to rotate about axis X3, which coincides with axis X2 when the container 12 is placed on the base 14.

[0101] The base 14 includes a protrusion 102 along axis X3 on its upper surface 100 for receiving the container 12, which is adapted to cooperate with the central opening 32 to form a centering device for aligning the container 12 on the base 14.

[0102] The magnetic blade 98 is positioned at the protrusion 102 so as close as possible to the magnetic insert 86.

[0103] When the container 12 is placed on the base 14, the magnetic attraction applied between the rotary stirrer 40, particularly the magnetic insert 86 and the magnetic blade 98, causes the rotary stirrer 40 to rotate when the magnetic blade 98 rotates.

[0104] like Figure 3As shown, the cover 16 includes a lower surface equipped with a receiving portion 106 for receiving the gripper 92. The receiving portion 106 is centered relative to the cover and ensures the alignment of the rod 42 and optimal retention of the processing assembly 13 within the container 12.

[0105] The lid 16 is adapted to be detachably secured to the container 12. Advantageously, the lid 16 is held secure to the container by form-fit or by the elastic deformation of a sealing ring around the inner wall 49 of the filling opening 18.

[0106] The operation and manner of the water treatment equipment 10 will now be described in order to better understand its operation and the technical advantages brought by the treatment components 13 and, more generally, the water treatment equipment 10.

[0107] During the first step, the user positions the processing assembly 13 inside the container 12. To do this, the user grasps the gripper 92 and passes the base 36 through the filling opening 18 until it contacts the bottom of the container 12. During this step, the centering element 48 ensures the centering position of the base 36 within the container and its translation along the inner wall 49. More advantageously, at the end of this step, the centering element 48, through its cooperation with the lower inner wall 49 of the container 12, ensures the processing assembly 13 is secured to the container 12.

[0108] The user then fills container 12 with water and closes it with lid 16. Grip 92 then cooperates with receiving portion 106, and the rod 42 is kept centered in container 12.

[0109] Subsequently, in the next step, the user places the container 12 on the base 14 and starts the motor 96, causing the magnetic blades 98 to rotate, thereby rotating the rotary mixer 40. The protruding part 102 ensures good centering and retention of the container on the base 14.

[0110] The rotary agitator 40 then generates vortices that facilitate the mixing and circulation of water, and drives the water to circulate successively through the upper opening 58, then through the inner through hole 62 and the outer through hole 64, so that the water rises along the inner wall 49 at the bottom of the container 12.

[0111] This operating method optimizes the circulation of water through the filter 38, particularly through the activated carbon, thereby facilitating water filtration. Furthermore, the housing dimensions facilitate the intake of water into the central cavity 54 and the discharge of water through the external through-hole 66, thus optimizing the flow rate through the filter 38 within a given time. Additionally, the centering element 48 ensures the spacing between the through-hole 66 and the inner wall 49, guaranteeing proper water discharge from the filter 38 after passing through it. Moreover, the frustoconical shape of the body 74 and the through-holes 64 and 66 ensure radial circulation of water through the filter, achieving optimal filtration performance. During operation of the water treatment equipment 10, water advantageously passes through the filter 38 multiple times.

[0112] Then, after a predetermined filtration time (e.g., between 3 and 15 minutes), the motor 96 is automatically stopped (e.g.), and an indicator light positioned on the base 14 signals that the filtration operation is complete and the water is ready to drink. Water thus passes through the filter 38 multiple times, thereby achieving optimized filtration performance.

[0113] In subsequent steps, once the water in container 12 has been consumed or has undergone a predetermined number of cycles (i.e., after a predetermined number of filtration operations), the user can remove the treatment element 13 for cleaning by manipulating the gripper 96 and sliding it upwards through the filling opening 18. Advantageously, the user can immerse the base in boiling water, for example, once a month, to regenerate the filtration capacity of filter 38, or regenerate it when the indicator light on the base is triggered after the motor has undergone a predetermined number of cycles. Furthermore, when the activated carbon contained in housing 52 has been used for more than a year, the user can replace the activated carbon by opening the housing, emptying the contents of the housing, and adding new activated carbon.

[0114] This operating method / arrangement extends the service life of the treatment component 13 while maintaining its filtration performance. Therefore, compared to existing products, the use of consumables is reduced, and the service life of the water treatment equipment and treatment components is significantly increased.

[0115] As a variation, container 12 includes a lower opening that allows the processing component 13 to be removed from container 12 via the bottom rather than by filling the upper opening 18.

[0116] Of course, the present invention is by no means limited to the embodiments described and shown, which are given by way of example only. In particular, modifications are possible in terms of the configuration of the elements or by substitution with technical equivalents, without departing from the scope of protection of the present invention.
