Technical Field

[0002] This disclosure relates to a filter assembly, and more specifically to a filter assembly capable of filtering water. Background Technology

[0003] Generally, a water purifier refers to a device used to filter water. Water purifiers remove impurities, heavy metals, and other contaminants from raw water by passing it through a filter. Such water purifiers may include a pretreatment filter to filter relatively large particles or residual chlorine from the raw water, a reverse osmosis (RO) filter to filter impurities such as heavy metals, and a post-carbon filter to improve the taste of the water.

[0004] Filters need to be replaced regularly. However, in existing technology, filters are only replaced when the bag and filter in the water purifier are in a relatively specific position, which makes the assembly and replacement process difficult. Summary of the Invention

[0005] This disclosure is intended to enable users to easily assemble and replace filters in water purifiers.

[0006] To achieve the above objectives, one aspect of this disclosure provides a filter assembly comprising: a filter module configured to filter raw water therein; and a bag module configured to house the filter module, wherein the bag module includes a bag body region having a receiving space S configured to communicate with the outside via one side of the bag body region in an outward longitudinal direction A1, wherein the filter module includes: a filter body region configured to be housed in the receiving space S; an inlet region formed on the outer surface of the filter body region in an inward longitudinal direction A2, the inward longitudinal direction being opposite to the outward longitudinal direction A1; and an outlet region formed on the outer surface of the filter body region in an inward longitudinal direction A2, wherein the inlet region and the outlet region are spaced apart from each other in a radial direction R of the filter module.

[0007] The filter module may also include a partition wall region disposed radially between the inlet and outlet regions and protruding from the filter body region in an inward longitudinal direction A2. The cross-section obtained by cutting the partition wall region in a direction perpendicular to the inward longitudinal direction A2 may have a closed curve shape.

[0008] The inlet area can be set outside the outlet area based on the radial direction R.

[0009] The exit area may include: a first exit area, which is disposed inside the inlet area based on a radial direction R; and a second exit area, which is disposed inside the first exit area based on a radial direction R.

[0010] The partition wall region may include: a first partition wall region disposed radially between the inlet region and the first outlet region; and a second partition wall region disposed radially between the first outlet region and the second outlet region.

[0011] The second outlet area can be formed at the center of the filter body area based on the radial direction R.

[0012] The entrance area, the first exit area, and the second exit area can be set on a straight line.

[0013] The entrance area and the first exit area can be set to face each other, with the second exit area inserted between the entrance area and the first exit area.

[0014] The entrance area and the second exit area can be configured to face each other, with the first exit area inserted between the entrance area and the second exit area.

[0015] The separator wall region can be inserted into the bag body region. The filter module may also include an O-ring member disposed on the following surface of the separator wall region, which is inserted into the bag body region and faces the bag body region in the radial direction R. The O-ring member can be inserted into the separator wall region.

[0016] The O-ring components can be configured as multiple O-ring components, and all of the multiple O-ring components can be inserted into the partition wall area. All of the multiple O-ring components are arranged in the area where the partition wall area and the bag body area face each other in the radial direction R.

[0017] According to this disclosure, users can easily assemble and replace the filter in a water purifier. Attached Figure Description

[0036] The filter assembly of the present invention will be described below with reference to the accompanying drawings.

[0037] The filter assembly according to this disclosure can be installed in and used in a water purifier to purify raw water. The filter assembly according to this disclosure can be applied to an RO filter configured to filter out impurities or a carbon filter configured to improve the taste of water.

[0039] The filter assembly 10 according to this disclosure may include a filter module 100 and a bag module 200. The filter module is configured to filter raw water in the filter module 100, and the bag module is configured to house the filter module 100 therein. More specifically, the filter module 100 may be configured to be attachable to or detachable from the bag module 200. As described below, according to this disclosure, the filter module 100 can be easily detached from the bag module 200 and easily assembled into the bag module 200.

[0040] like Figures 1 to 3 As shown, the bag module 200 may include a bag body region 210 and a bag fixing region 220. The bag body region has a receiving space S, which is configured to communicate with the outside through one side of the bag body region 210 based on the outward longitudinal direction A1 of the filter assembly 10. The bag fixing region is disposed on one side of the bag body region 210 based on the outward longitudinal direction A1. Meanwhile, in this specification, the direction in which the filter module 100 is detached from the bag module 200 along the length of the filter assembly (based on...) Figure 2 The leftward direction is defined as the outward longitudinal direction A1, which is the direction in which the filter module 100 is assembled into the bag module 200 (based on...). Figure 2 The rightward direction is defined as the inward longitudinal direction A2.

[0041] Meanwhile, the filter module 100 may include a filter body region 110 and a filter relief region 120. The filter body region is configured to be housed in a receiving space S. The filter relief region is disposed on the outer peripheral surface of one side of the filter body region 110 based on an outward longitudinal direction A1 and is configured to be connected to the bag fixing region 220. As described below, based on the assembled state of the filter module 100 and the bag module 200, the filter relief region 120 can be connected to the bag fixing region 220, thereby preventing the filter module 100 from being spaced apart from the bag fixing region 220 in the outward longitudinal direction A1.

[0042] In addition, such as Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the bag module 200 may further include a pop-out region 230, which is configured to face the filter body region 110 and press the filter module 100 in the outward longitudinal direction A1 when the filter module 100 is received in the receiving space S. When the filter module 100 is assembled to the bag module 200, the pop-out region 230 can press the filter module 100 in the outward longitudinal direction A1. As described below, when the filter concave-convex region 120 and the bag fixing region 220 are physically separated, the pop-out region 230 presses the filter module 100 in the outward longitudinal direction A1, allowing the filter module 100 to smoothly separate from the bag module 200.

[0043] More specifically, the pop-up area 230 may include a pop-up spring member 232 and a pop-up pressing member 234. The pop-up spring member is housed on one side of the receiving space S in the main body area 210 of the bag portion, and the pop-up pressing member is disposed on one side of the pop-up spring member 232. More specifically, the pop-up pressing member 234 may be configured to face the filter concave-convex area 120, wherein the filter main body area 110 is inserted between the pop-up pressing member 234 and the filter concave-convex area 120. The pop-up spring member 232 and the filter main body area 110 may be configured to face each other in the outward longitudinal direction A1, wherein the pop-up pressing member 234 is inserted between the pop-up spring member 232 and the filter main body area 110. Therefore, the pop-up spring member 232 can press the filter main body area 110 in the outward longitudinal direction A1 by the pop-up pressing member 234.

[0044] At the same time, such as Figure 9 and Figure 10 As shown, the bag fixing region 220 may include a button member 221 and a plate member 222. The button member is configured to move in a first width direction W1 perpendicular to the outward longitudinal direction A1. The plate member is configured to interfere with the button member 221 and is configured to move via the button member 221 in a direction intersecting the outward longitudinal direction A1. It also has an opening H configured to connect the receiving space S to the outside. More specifically, in the assembled state of the filter module 100 and the bag module 200 (see...), Figure 8 The filter's uneven area 120 and the plate member 222 interfere with each other, so that the filter's uneven area 120 and the bag fixing area 220 can be fixed.

[0045] Furthermore, according to this disclosure, the bag fixing region 220 may also include a configuration configured as a pressing plate member 222. More specifically, the bag fixing region 220 may also include a spring member 223 configured to press the pressing plate member 222 toward the hole H. The spring member 223 can be configured to press the pressing plate member 222, thereby causing the plate member 222 and the filter uneven region 120 to continue to interfere with each other. Therefore, according to this disclosure, the filter module 100 and the bag module 200 can be stably maintained in an assembled state.

[0046] Furthermore, according to one example of this disclosure, the aforementioned plate member 222 may include multiple components. More specifically, the plate member 222 may include a first plate member 222a and a second plate member 222b, the first plate member being configured to form part of a defining hole H on the inner surface of the plate member 222, and the second plate member being configured to form another part of the defining hole H on the inner surface of the plate member 222. In particular, the plate member 222 may include the first plate member 222a and the second plate member 222b. The first plate member 222a and the second plate member 222b may have shapes symmetrical to each other.

[0047] Simultaneously, an inclined surface can be formed in the area where the first plate member 222a and the second plate member 222b contact the button member 221. More specifically, as... Figure 9 and Figure 10 As shown, the first-first inclined surface 222-1 can be formed on i) the surface of the first plate member 222a that is configured to contact the button member 221 and ii) the surface of the second plate member 222b that is configured to contact the button member 221, respectively. The first-first inclined surface 222-1 extends to be inclined at a predetermined angle relative to the first width direction W1.

[0048] In this configuration, the spring member 223 can be disposed between the inner surface of the bag body region 210 and the plate member 222, and the second width direction W2 can intersect perpendicularly with the first width direction W1. This second width direction W2 is the direction in which the inner surface of the bag body region 210 and the plate member 222 face each other, wherein the spring member 223 is inserted between the inner surface of the bag body region 210 and the plate member 222. In this configuration, as... Figure 9 and Figure 10 As shown, based on the cross-section obtained by cutting the first-first inclined surface 222-1 in a direction perpendicular to the outward longitudinal direction A1, the first-first inclined surface 222-1 can be extended to be inclined at a predetermined angle relative to the second width direction W2.

[0049] The operating principle of the bag fixing area 220 will be described below based on the above explanation. For example... Figure 9As shown, when the button member 221 is pressed inward along the first width direction W1, the first plate member 222a and the second plate member 222b, which are in contact with the button member 221, are pressed outward along the second width direction W2 via the first-first inclined surface 222-1, causing the hole H to enlarge. This first-first inclined surface 222-1 intersects the first width direction W1, the second width direction W2, and the length directions A1 and A2. With the hole H enlarged, the filter module 100 can be accommodated in the accommodating space S through the hole H. In this case, the spring member 223 is compressed by the plate member 222, which is pushed outward along the second width direction W2.

[0050] Alternatively, when the filter module 100 is assembled into the bag module 200, the filter module 100, which is normally pressed by the pop-out area 230, can be separated from the bag module 200 when the button member 221 is pressed inward along the first width direction W1 to enlarge the hole H.

[0051] Then, as Figure 10 As shown, when the force applied to the button member 221 is removed, the first plate member 222a and the second plate member 222b move inward along the second width direction W2 by the force applied to the plate member 222 by the compressed spring member 223, causing the hole H to contract. Therefore, when the hole H contracts, the plate member 222 and the filter concave-convex region 120 can interfere with each other, thereby preventing the filter module 100 from separating from the bag module 200 in the outward longitudinal direction A1.

[0052] Continue to refer to Figure 5 and Figure 8 The inner surface of the first plate member 222a or the inner surface of the second plate member 222b may further include a first-second inclined surface 222-2, which is positioned laterally outward in the outward longitudinal direction A1. When the filter module 100 is inserted into the receiving space S of the bag module 200, the first-second inclined surface 222-2 can be configured to allow the filter concave-convex region 120 to enter smoothly while pushing the plate member 222 outward. That is, according to this disclosure, even if the user simply pushes the filter module 100 into the bag module 200 without manipulating the button member 221, the hole H defined by the plate member 222 can be enlarged so that the filter module 100 can be smoothly inserted into the bag module 200.

[0053] Figure 11 It is a view used to show the shape of the filter's raised and recessed areas in the filter assembly according to this disclosure.

[0054] like Figure 11As shown, the filter's uneven region 120 may include a second inclined surface 122 formed in the region corresponding to the first-second inclined surface 222-2, and the second inclined surface 122 is positioned outwardly oriented in the outward longitudinal direction A1. More specifically, during the insertion of the filter module 100 into the bag module 200, the second inclined surface 122 may be configured to contact the first-second inclined surface 222-2. Therefore, during the insertion of the filter module 100 into the bag module 200, the second inclined surface 122 may push the first-second inclined surface 222-2 outward. More specifically, the angle defined between the second inclined surface 122 and the longitudinal directions A1 and A2 may correspond to or be equal to the angle defined between the first-second inclined surface 222-2 and the longitudinal directions A1 and A2.

[0055] Continue to refer to Figure 11 The filter recessed area 120 may further include a first recessed surface 124, which is configured to be spaced apart from the second inclined surface 122 in the outward longitudinal direction A1 and has an inwardly recessed shape. Based on the assembled and connected state of the filter module 100 and the bag module 200, the first-second inclined surface 222-2 of the plate member 222 can be accommodated in the space defined by the first recessed surface 124 (see...). Figure 8 ).

[0056] At the same time, such as Figure 11 As shown, according to this disclosure, the filter recessed area 120 may further include a second recessed surface 126, which is configured to be spaced apart from the first recessed surface 124 in the outward longitudinal direction A1 and has an inwardly recessed shape. The second recessed surface 126 may be configured to provide space for inserting another external tool (e.g., a screwdriver) in an emergency situation where the filter module 100 cannot be separated from the bag module 200 by pressing the button member 221. More specifically, the second recessed surface 126 may be formed at the end of the filter recessed area 120 based on the outward longitudinal direction A1.

[0057] Figure 12 This is a second perspective view of the filter component according to this disclosure.

[0058] At the same time, such as Figure 12As shown, the filter module 100 may further include a connecting member 130, which is attached to the outer surface of the filter body region 110 in an outward longitudinal direction A1. Similar to the second recessed surface 126, the connecting member 130 may also be configured to provide an area for a user to hold and pull the filter module 100 in an emergency situation where the filter module 100 cannot be separated from the bag module 200. For this purpose, the surface of the connecting member 130 facing the filter body region 110 may include an attachment surface 132 and a non-attachment surface 134. The attachment surface 132 has an adhesive material applied thereto and is attached to the filter body region 110, while the non-attachment surface 134 is disposed on one side of the attachment surface 132 and spaced apart from the filter body region 110. More specifically, the non-attachment surface 134 may not be attached to the filter body region 110. Therefore, the non-attachment surface 134 may be an area configured to be gripped by a user. Therefore, with the user gripping the non-attached surface 134, the user can pull the filter module 100 in the outward longitudinal direction A1.

[0059] Figure 13 This is a cross-sectional view of the filter module disposed in the filter assembly according to this disclosure, and Figure 14 This is a view showing the inlet area, outlet area, and partition wall area disposed in the filter module according to this disclosure. Figure 15 This is a view illustrating another example of the inlet area, outlet area, and partition wall area arranged in a filter module according to this disclosure, and Figure 16 This is a cross-sectional view showing the state in which the filter module according to this disclosure is inserted and connected to the bag module.

[0060] Additionally, according to this disclosure, the filter body region 110 may be further configured to provide a path for introducing raw water intended for purification into the filter module 100 and discharging purified water.

[0061] More specifically, such as Figures 13 to 15 As shown, the filter module 100 may further include an inlet region 140 and an outlet region 150. The inlet region 140 is formed on the outer surface of the filter body region 110 based on an inward longitudinal direction A2, which is opposite to the outward longitudinal direction A1. The outlet region 150 is formed on the outer surface of the filter body region 110 based on the inward longitudinal direction A2. The inlet region 140 provides a path for supplying fluid (e.g., raw water) into the filter module 100, and the outlet region 150 provides a path for discharging fluid (e.g., purified water, wastewater) from the interior of the filter module 100 to the exterior. In this case, according to the present disclosure, the inlet region 140 and the outlet region 150 may be arranged to be spaced apart from each other in the radial direction R of the filter module 100.

[0062] Furthermore, the filter module 100 may also include a partition wall region 160 disposed between the inlet region 140 and the outlet region 150 along a radial direction R perpendicular to the longitudinal directions A1 and A2, and protruding from the filter body region 110 along the inward longitudinal direction A2. The partition wall region 160 may be configured to prevent fluid introduced into the filter module 100 through the inlet region 140 and fluid discharged from the filter module 100 through the outlet region 150 from mixing with each other. To achieve the above objective, the cross-section obtained by cutting the partition wall region 160 in a direction perpendicular to the inward longitudinal direction A2 may have a closed curve shape. More specifically, the partition wall region 160 may have a circular cross-sectional shape.

[0063] Meanwhile, for example, the inlet region 140 may be positioned outside the outlet region 150 based on a radial direction R. Furthermore, the outlet region 150 may be configured as a single outlet region 150. Alternatively, the outlet region 150 may be configured as multiple outlet regions 150. More specifically, the outlet region 150 may include a first outlet region 151 and a second outlet region 152, the first outlet region 151 being positioned inside the inlet region 140 based on a radial direction R, and the second outlet region 152 being positioned inside the first outlet region 151 based on a radial direction R. When the outlet region 150 is configured as a single outlet region 150, the filter assembly can be applied to a carbon filter. When the outlet region 150 includes a first outlet region 151 and a second outlet region 152, the filter assembly can be applied to an RO filter. For example, the first outlet region 151 may be configured to discharge fluid containing foreign matter (e.g., wastewater) to the outside, and the second outlet region 152 may be configured to discharge fluid with foreign matter removed (e.g., purified water) to the outside.

[0064] Meanwhile, when the exit area 150 includes a first exit area and a second exit area, the partition wall area 160 can be configured as multiple partition wall areas 160 corresponding to the first exit area and the second exit area. More specifically, as... Figure 14As shown, the partition wall region 160 may include a first partition wall region 161 and a second partition wall region 162. The first partition wall region 161 is radially disposed between the inlet region 140 and the first outlet region 151, and the second partition wall region 162 is radially disposed between the first outlet region 151 and the second outlet region 152. The first partition wall region 161 and the second partition wall region 162 may each have a closed-curve cross-sectional shape. More specifically, the first partition wall region 161 and the second partition wall region 162 may have a concentric circular cross-sectional shape. Meanwhile, for example, the second outlet region 152 may be formed at the center of the filter body region 110 based on the radial direction R.

[0065] Continue to refer to Figure 14 and Figure 15 The entrance area 140, the first exit area 151, and the second exit area 152 can be arranged in a straight line. For example, as shown... Figure 14 As shown, the inlet region 140 and the first outlet region 151 can be configured to face each other, with the second outlet region 152 inserted between the inlet region 140 and the first outlet region 151. However, in another example, as... Figure 15 As shown, the inlet area 140 and the second outlet area 152 can be configured to face each other, wherein the first outlet area 151 is inserted between the inlet area 140 and the second outlet area 152.

[0066] At the same time, refer to Figures 14 to 16 The partition wall region 160 can be inserted into the main body region 210 of the bag portion. In this case, the configuration in which the partition wall region 160 is inserted into the main body region 210 of the bag portion can be a configuration in which a concave-convex region can be formed on the inner surface of the main body region 210 oriented toward the partition wall region 160, and the partition wall region 160 can be inserted into the concave-convex region and can prevent movement in the radial direction R.

[0067] In addition, such as Figure 16As shown, according to this disclosure, the filter module 100 may further include an O-ring member 170 disposed on a surface of the partition wall region 160 that inserts into the bag body region 210 and faces the bag body region 210 in the radial direction R. The O-ring member 170 may be configured to ensure a seal in the region where the partition wall region 160 and the bag body region 210 are joined. In this case, for example, the O-ring member 170 may be inserted into the partition wall region 160. Multiple O-ring members 170 may be provided. More specifically, all of the multiple O-ring members 170 may be inserted only into the partition wall region 160 and not into the bag body region 210, and all of the multiple O-ring members 170 may be arranged in the regions where the partition wall region 160 and the bag body region 210 face each other in the radial direction R.

[0068] Figure 17 This is an enlarged cross-sectional view showing the button component and surrounding components of the pocket module according to this disclosure, and showing the state of the button component before it is pressed. Figure 18 This is an enlarged cross-sectional view showing the button component and surrounding components of the pocket module according to the present disclosure, and showing the state of the button component after it has been pressed.

[0069] Even if the pop-up area 230 fails to function, the filter assembly according to this disclosure may also include a structure that ensures the filter module 100 can be separated from the bag module 200 by manual operation.

[0070] More specifically, according to this disclosure, before the button member 221 is pressed, the button member 221 is spaced apart from the filter relief region 120. When the button member 221 is pressed, a portion of the button member 221 may interfere with the filter relief region 120. That is, as Figure 17 and Figure 18 As shown, the button component 221 may include a button extension region 221a having a shape that protrudes toward the filter relief region 120. For example, the button extension region 221a includes regions extending in the outward longitudinal direction A1 and the inward longitudinal direction A2, such that the button extension region 221a may have a tortuous cross-sectional shape.

[0071] In this case, with the filter module 100 housed in the bag module 200, the button extension region 221a can be configured to face the second inclined surface 122 of the filter recessed region 120, and the region of the button extension region 221a facing the second inclined surface 122 can have a shape corresponding to the second inclined surface 122. Therefore, according to this disclosure, before the button member 221 is pressed, the button extension region 221a is spaced apart from the second inclined surface 122 (see [link to disclosure]).
