Description

Technology Field

[0001] The present invention relates to a water softener. Background Technology

[0002] Generally, tap water supplied to households contains a large amount of chlorine during the purification process, and may also contain hardness components such as calcium ions and magnesium ions. If users consume tap water containing these hardness components as is, it may not be fatal to the human body, but it can cause various skin diseases such as allergies or accelerate skin aging.

[0003] As a result, the development of water softeners that provide users with tap water from which hardness components have been removed (hereinafter referred to as "soft water") is actively underway. Such water softeners can provide users with soft water from which calcium ions and magnesium ions have been removed by exchanging calcium ions and magnesium ions contained in raw water with sodium ions.

[0004] These water softeners are equipped with a softening tank and a regeneration tank. The softening tank contains ion exchange resin with a high concentration of NaCl, while the regeneration tank holds NaCl to regenerate the ion exchange resin when the concentration of NaCl within the resin in the softening tank decreases. When the NaCl in the regeneration tank is depleted, the tank must be removed to replenish the NaCl.

[0005] However, conventional water softeners have a problem in that the regeneration tank is positioned at the top and moves vertically upward to detach from the water softener, making it difficult for the user to remove the tank. In other words, the user must apply upward force toward a high point to detach the tank, requiring a significant amount of force.

[0006] In this regard, Korean Published Patent Application 10-2019-0035295 by the present applicant, "Separable regeneration tank of a water softener and drain basket of a regeneration tank" (Patent Document 1), discloses a water softener comprising a separable regeneration tank. Additionally, Korean Published Patent Application 10-2009-0025018 by the present applicant, "Water softener tank" (Patent Document 2), discloses a regeneration tank that is separably disposed on the upper side of a water softener.

[0007] However, since the regeneration tank of Patent Document 1 and the regeneration tank of Patent Document 2 must be moved vertically upward to be separated from the water softener, there is a problem that it is difficult for users who are short or physically disabled to separate the regeneration tank. In other words, according to Patent Document 1 and Patent Document 2, there is a problem that it is difficult to separate the regeneration tank because the user must move the regeneration tank vertically upward to separate it. Since the regeneration tank requires periodic maintenance such as cleaning, the difficulty in separating the regeneration tank is a problem that cannot be ignored. Prior art literature

For the same reason, some components in the attached drawings may be exaggerated, omitted, or schematically depicted, and the size of each component does not entirely reflect its actual size.

[0026] Additionally, terms including ordinal numbers, such as first, second, etc., may be used to describe various components, but such components are not limited by such terms. These terms are used solely for the purpose of distinguishing one component from another.

[0027] The meaning of "comprising" as used in the specification specifies certain characteristics, areas, steps, actions, elements and / or components, and does not exclude the existence or addition of other specific characteristics, areas, steps, actions, elements, components and / or groups.

[0028] Hereinafter, a water softener (1) according to one embodiment of the present invention will be described with reference to the drawings.

[0029] Referring to FIGS. 1 and 2, a water softener (1) is installed on a bathroom wall or the like to provide softened water by chemically changing the hard water ions contained in raw water, or to provide purified water to the user by filtering raw water. Hereinafter, among the water flowing into the water softener (1) from the outside, water that has not passed through a water purification filter is defined as raw water, and water that has been filtered through a water purification filter is defined as purified water. The water softener (1) may include a body (100), a tank unit (200), a shower head mounting part (300), a flow path unit (400), a regeneration tank (500), a support member (600), a hand shower (700), and a rain shower (800).

[0030] The body (100) can support a tank unit (200), a shower head mounting part (300), a flow path unit (400), a regeneration tank (500), a support member (600), a handheld shower (700), and a rain shower (800). Additionally, the body (100) may be a housing that provides the overall appearance of the water softener (1). This body (100) may be installed indoors such that its rear surface contacts the wall of the room, but is not limited thereto. Inside this body (100), an internal receiving space (110) capable of accommodating the tank unit (200), the shower head mounting part (300), the flow path unit (400), the regeneration tank (500), and the support member (600) may be provided.

[0031] The body (100) may include a guide (120) that guides the rotation of the regeneration container (500). The guide (120) engages with a latching part (520) to be described later, provided in the regeneration container (500), and the latching part (520) can move along the guide (120). Such a guide (120) may be positioned on the left and right sides inside the body.

[0032] The guide (120) may extend in an arc shape from the upper side of the body (100) toward the front and may have a predetermined curvature centered on a rotation axis (Ax1). Additionally, the front side of the guide (120) may have a connecting part (520) of the regeneration container (500) connected to the guide (120). By means of this guide (120), the regeneration container (500) may rotate around a rotation axis (Ax1) oriented in a horizontal direction. The horizontal direction may be the left and right direction of the water softener (1).

[0033] The tank unit (200) can provide one or more of purified water and soft water. Additionally, the tank unit (200) can chemically soften raw water or purified water to provide soft water. For example, the tank unit (200) can [pronounce] calcium ions (Ca ions) contained in the purified water or raw water. 2 + ) and magnesium ions (Mg 2 +) sodium ions (Na + ) exchange with calcium ions (Ca 2 + ) and magnesium ions (Mg 2 + Softened water with ) removed can be produced. Such a tank unit (200) may include a water purification filter (210) and a water softening tank (220).

[0034] The water purification filter (210) can filter raw water flowing into the water softener (1) to provide purified water. Additionally, the water purification filter (210) can provide purified water to one or more of the water softening tank (220), the hand shower (700), and the rain shower (800). For example, this water purification filter (210) may include a ceramic filter to remove rust contained in the raw water. However, this is merely an example, and the water purification filter (210) may include well-known filters such as a pre-filter, an activated carbon filter, and a microfilter.

[0035] The water softening tank (220) can provide softened water by ion-exchanging purified water with an ion-exchange resin. The ion-exchange resin of the water softening tank (220) may contain sodium chloride (NaCl) in a high proportion. The purified water introduced into the water softening tank (220) ions calcium ions (Ca 2 + ) or magnesium ions (Mg 2 + When ion exchange occurs with cations such as ), the hardness components contained in the purified water are sodium (Na + It is replaced by ) and adsorbed onto the ion exchange resin, and the sodium (Na) contained in the ion exchange resin + ) is included in the purified water to become soft water. When this ion exchange resin is used a predetermined number of times, the concentration of sodium chloride decreases, so it can no longer remove cations. In this case, the ion exchange resin is not replaced, and the concentration of sodium chloride in the ion exchange resin is increased through a regenerating agent containing sodium ions. Additionally, the water softening tank (220) can provide soft water to one or more of a hand shower (700) and a rain shower (800).

[0036] The shower head mounting part (300) is positioned inside the body (100) to mount a handheld shower (700). The handheld shower (700) can be accommodated inside the body (100) by this shower head mounting part (300).

[0037] The flow unit (400) may provide a passage for one or more of raw water, purified water, and regenerated water to flow. The flow unit (400) may flow raw water introduced into the water softener (1) to one or more of the regeneration tank (500) and the tank unit (200), and may flow regenerated water discharged from the regeneration tank (500) to the water softening tank (220). Additionally, the flow unit (400) may flow purified water or softened water discharged from the tank unit (200) to one or more of the hand shower (700) and the rain shower (800). Such a flow unit (400) may include a combined flow member (410), a discharge flow (420), a raw water supply flow (430), a regenerated water flow (440), and a shower connection flow (450).

[0038] Referring further to FIGS. 3 and 4, the connecting channel member (410) is configured to be detachably connected to the regeneration tank (500) and may be in communication with the raw water supply channel (430) and the regeneration water channel (440). In other words, at least a portion of the raw water flowing in the raw water supply channel (430) flows into the regeneration tank (500) through the connecting channel member (410), and the regeneration water discharged from the regeneration tank (500) may flow back into the tank unit (200) through the connecting channel member (410). Additionally, the connecting channel member (410) is supported by a support member (600) and may rotate around a rotation axis (Ax1) when the regeneration tank (500) is rotated. These combined flow path members (410) may include a discharge part combined flow path (411), a rotational flow path (412), and a locking part (413).

[0039] The discharge section connecting channel (411) can be configured to allow the regeneration tank (500) to be detachably connected. When raw water flows into the regeneration tank (500), the raw water is introduced into the regeneration tank (500) through the discharge section connecting channel (411), and when regeneration water is discharged from the regeneration tank (500), the regeneration water can be discharged through the discharge section connecting channel (411) to the rotation channel (412) and the regeneration water supply channel. The discharge section connecting channel (411) is positioned at the center of the rotation channel (412) and can accommodate at least a portion of the flow opening (530) of the regeneration tank (500), which will be described later.

[0040] The rotational channel (412) is connected to the discharge unit coupling channel (411) and is supported by a support member (600) and positioned on a rotation axis (Ax1) so that it can rotate around the rotation axis (Ax1). For example, both sides of the rotational channel (412) may be rotatably supported by the support member (600). This rotational channel (412) can rotate around the rotation axis (Ax1) together with the discharge unit coupling channel (411). Additionally, one side (e.g., the left side) of the rotational channel (412) may be connected to the raw water supply channel (430), and the other side (e.g., the right side), which is opposite to the one side, may be connected to the regenerated water channel (440). The raw water discharged from the raw water supply channel (430) by this rotating channel (412) flows into the discharge unit connecting channel (411), and the regenerated water discharged from the discharge unit connecting channel (411) can flow into the regenerated water channel (440).

[0041] Referring further to FIGS. 5 and 6, the catch portion (413) extends from the rotational channel (412) in a direction perpendicular to the rotational axis (Ax1) and interferes with a plurality of ribs (610, 620) of the support member (600) to be described later, thereby limiting the rotation of the regeneration container (500).

[0042] The discharge channel (420) can discharge the regenerated water overflowing from the regeneration tank (500) to the outside of the body (100). The discharge channel (420) may have an upper part that is adjacent to the discharge projection (541) of the regeneration tank (500) which will be described later, having a predetermined gap, and a lower part that is connected to the lower part of the body (100). The regenerated water overflowing through this discharge channel (420) can flow downward and be discharged to the outside of the body (100).

[0043] The raw water supply channel (430) can flow raw water supplied from the raw water supply source to one or more of the combined channel member (410) and the tank unit (200). Additionally, the raw water supply channel (430) is connected to one side of the rotating channel (412) so that at least a portion of the raw water can flow to one side of the rotating channel (412).

[0044] The regenerated water channel (440) can flow the regenerated water discharged from the combined channel member (410) to the tank unit (200). In other words, the regenerated water channel (440) is connected to the other side of the rotating channel (412) and can flow the regenerated water discharged from the rotating channel (412) to the softened water tank (220) of the tank unit (200).

[0045] The shower connection path (450) can provide a path for soft water or purified water discharged from the tank unit (200) to flow into one or more of the hand shower (700) and the rain shower (800).

[0046] Referring further to FIG. 7, the regeneration tank (500) is detachably coupled to the body (100) and the coupling channel member (410) and can generate regenerated water by receiving raw water. Additionally, the regeneration tank (500) may contain a regenerating agent such as sodium chloride. This regenerating agent may be dissolved by the raw water flowing into the regeneration tank (500) to form regenerated water. The regeneration tank (500) may be positioned on the upper side of the body (100), but is not limited thereto.

[0047] The regeneration container (500) can be rotated around a rotation axis (Ax1). When the regeneration container (500) is rotated so that its upper surface faces upward, it can be placed in an inseparable state where it cannot be separated from the body (100). When the regeneration container (500) is in an inseparable state, the upper surface of the regeneration container (500) can be positioned parallel to a virtual horizontal plane and positioned above the rotation axis (Ax1). On the other hand, when the regeneration container (500) is rotated downward, it can be placed in a separable state where it can be separated from the body (100). When the regeneration container (500) is in a separable state, the upper surface of the regeneration container (500) can be oriented to form a predetermined angle with respect to the horizontal plane (ground). For example, the regeneration container (500) can be rotated so that its upper surface is positioned forward of the rotation axis (Ax). When this regeneration container (500) is in a detachable state, it can be separated from the body (100) by moving it in a direction tilted forward rather than in the up-and-down direction of the body (100) by the user.

[0048] The regeneration container (500) may include a regeneration container body (510), an interlocking part (520), a flow hole (530), a discharge body (540), and a regeneration agent basket (550).

[0049] The regeneration tank body (510) can store raw water flowing in from the flow port (530). Regeneration water is generated by dissolving a regeneration agent in the raw water stored within the regeneration tank body (510), and the generated regeneration water can be discharged through the flow port (530). This regeneration tank body (510) can be rotated around a rotation axis (Ax1). Additionally, the upper surface of the regeneration tank body (510) can be open to accommodate a regeneration agent basket (550).

[0050] Referring again to FIGS. 5 and 6, the engaging portion (520) may be protruded or recessed from both sides of the regeneration container body (510) and may be moved by engaging with the guide (120) when the regeneration container body (510) is rotated. When the regeneration container (500) is in a separable state, the engaging portion (520) may be positioned at the front end of the guide (120) and detached from the guide (120). Additionally, when the regeneration container (500) is in a non-separable state, the engaging portion (520) may be positioned at the rear end of the guide (120).

[0051] The flow channel (530) may provide a passage for raw water to flow into the regeneration tank body (510) or a passage for regeneration water to be discharged from the regeneration tank body (510) when the regeneration tank (500) is in a non-separable state. This flow channel (530) may be detachably coupled to the discharge part coupling channel (411) of the coupling channel member (410). For example, the flow channel (530) may protrude downward from the regeneration tank body (510) and be detachably inserted into the discharge part coupling channel (411). The flow channel (530) may be separated from the discharge part coupling channel (411) when the regeneration tank (500) is in a separable state. Additionally, the flow channel (530) and the discharge part coupling channel (411) may be arranged in a direction offset from the vertical direction of the body (100) when the regeneration tank (500) is in a separable state.

[0052] The discharge body (540) may have a height lower than the top of the regeneration tank body (510) so that the regeneration water overflowing within the regeneration tank body (510) flows in. The overflowing regeneration water may refer to the regeneration water that overflows from the regeneration tank body (510) and flows into the discharge body (540) when the water level of the regeneration water stored in the regeneration tank body (510) rises higher than the top of the discharge body (540). Such a discharge body (540) may be configured through a partition wall connected to the inner side of the regeneration tank body (510), but is not limited thereto.

[0053] Additionally, the discharge body (540) may be provided with a discharge projection (541) that protrudes downward and has a discharge hole formed therein through which the overflowed regenerated water can be discharged. The discharge projection (541) may be positioned adjacent to the upper part of the discharge channel (420). In other words, the overflowed regenerated water can be discharged outside the body (100) through the discharge projection (541) and the discharge channel (420).

[0054] The support member (600) can support the coupling channel member (410) so that the coupling channel member (410) can rotate. This support member (600) can be placed between the tank unit (200) and the regeneration tank (500). Additionally, the support member (600) can interfere with the coupling channel member (410) when the regeneration tank (500) is in a separable or non-separable state so that it can rotate within a predetermined range, thereby preventing the regeneration tank (500) from rotating excessively. In other words, the rotation range of the regeneration tank (500) can be determined by the support member (600).

[0055] Additionally, the support member (600) may include a plurality of ribs (610, 620) protruding in a direction parallel to the rotation axis (Ax1). The plurality of ribs (610, 620) may include a first rib (610) and a second rib (620). The first rib (610) may contact the locking part (340) when the regeneration container (500) is in a non-separable state, and the second rib (620) may contact the locking part (340) when the regeneration container (500) is in a separable state.

[0056] The handheld shower (700) can provide the user with softened or purified water. In other words, purified or softened water can be introduced into the handheld shower (700) from the shower connection channel (450). Additionally, the handheld shower (700) can be mounted on the shower mounting part (300).

[0057] The rain shower (800) is connected to the upper side of the body (100) and can provide soft or purified water to the user. In other words, purified or soft water can be introduced into the rain shower (800) from the shower connection channel (450).

[0058] Hereinafter, the operation and effect of a water softener (1) according to one embodiment of the present invention will be described.

[0059] According to one embodiment of the present invention, the regeneration container (500) of the water softener (1) can be rotated around a rotation axis (Ax1) to be in a non-separable or separable state. The user can easily separate the regeneration container (500) from the body (100) by rotating it forward to position it in a separable state and then lifting the regeneration container (500) toward the upper front side. Therefore, even a user with a small stature can easily separate the regeneration container (500).

[0060] Additionally, since the regeneration container (500) and the coupling channel member (410) can be rotated simultaneously in the same direction, the coupling channel member (410) can be oriented toward the direction in which the flow hole (530) of the regeneration container (500) is coupled. In other words, when the regeneration container (500) is removed from the body, the coupling channel member (410) can be tilted toward the front side in the same direction as the regeneration container (500) is removed. Therefore, when coupling the separated regeneration container (500), the user can connect the regeneration container (500) in the direction opposite to the direction in which it was removed without needing to adjust the orientation of the coupling channel member (410). In other words, the user can connect the regeneration container (500) to the coupling channel member (410) simply by the action of mounting the regeneration container (500) to the body (100).

[0061] Although embodiments of the present invention have been described as specific forms, they are merely illustrative and the present invention is not limited thereto, but should be interpreted as having the broadest scope in accordance with the technical concept disclosed herein. Those skilled in the art may implement patterns of shapes not specified by combining or substituting the disclosed embodiments, and this also does not deviate from the scope of the present invention. Furthermore, those skilled in the art may easily modify or alter the disclosed embodiments based on this specification, and it is evident that such modifications or alterations also fall within the scope of the present invention.
