Description

The present invention relates to a holder for holding an undersink type water purifier installed under the sink in the kitchen, and a water purifier having the holder.

Conventionally, as a water purifier for purifying tap water, a faucet direct connection type water purifier directly connected to the outlet of a tap water faucet, a stationary water purifier used by placing it on the kitchen, and an undersink used by placing it inside the kitchen. Type (or built-in type) water purifiers are known. In both cases, the total amount of filtered water that can be processed by the filter medium filled in the filter cartridge for the water purifier is limited, so the user continues to use the water purifier while regularly replacing the filter cartridge for the water purifier.

The undersink type water purifier is larger than the faucet direct connection type water purifier and the stationary water purifier, and the total amount of filtered water that can be treated is large, so that it can be used for a long period of time. There is no water purifier near the faucet or sink in the kitchen, so it does not get in the way of work.

As an undersink type water purifier, for example, as in Patent Document 1, a hose having a raw water inlet and a water purification outlet and having a one-touch joint attached to the tip is connected and used. The user places the water purifier cartridge on the bottom of the space under the sink, and connects the hose for supplying raw water and the hose for discharging purified water. Purified water can be easily obtained by operating the faucet in the kitchen.

Further, the arrangement in which the water purifier cartridge is placed on the bottom surface of the space under the sink as in Patent Document 1 reduces the storage space below the kitchen, which is not possible in recent mainstream kitchens in which a drawer is provided in the space below the sink. Due to some problems, it has been proposed to suspend and install a water purifier in the space under the top plate of the kitchen sink as in Patent Document 2.

As shown in FIG. 1, on the back wall (not shown) of the space under the sink of the kitchen, for example, the filter cartridge 2 of the water purifier 1 is attached to the grip member 301 from the direction perpendicular to the central axis of the cylinder. It is gripped and attached to the water purifier holder 300. The water purifier holder 300 is composed of two gripping members 301 having an opening 312 and a mounting member 302 fixed to the wall surface, and has two upper and lower gripping members 301 (first gripping portion 305, second gripping portion 306). ) Holds the outside of the columnar filter cartridge 2.

FIG. 2 is a perspective view showing a water purifier holder 300 when the water purifier 1 is vertically mounted as shown in FIG. The gripping member 301 has a substantially C shape, and the inner diameter dh of the gripping member 301 is preferably 0.9 df or more and 1 df or less with respect to the outer diameter df of the filter cartridge 2 shown in FIG. When the inner diameter dh is 0.9 df or more, the filter cartridge 2 can be removed with an appropriate force. If the inner diameter dh is 1 df or less, the filter cartridge 2 can be prevented from falling off.

Further, the distance between both ends of the opening 312 of the gripping member 301 is smaller than the diameter of the cylindrical filter cartridge 2, and the opening tip 319 of the opening 312 is opened first in order to improve insertability. It has an inviting shape to ensure a secure fit after inserting the filter cartridge 2. The opening distance dp of the opening tip 319 is preferably 0.7 df or more and 0.9 df or less with respect to the outer diameter df of the filter cartridge 2 shown in FIG. When the opening distance dp is 0.7 or more, the filter cartridge 2 can be removed with an appropriate force. When the opening distance dp is 0.9 df or less, it is possible to prevent the filter cartridge 2 from falling off. Further, the opening tip 319 is provided with a reinforcing rib 318, and when the filter cartridge 2 comes into contact with the opening tip 319 and a force is applied, the opening tip 319 can be prevented from being deformed or broken. Further, the reinforcing rib 318 is also effective as a strength improving reinforcing rib in which the substantially C-shaped gripping member 301 firmly grips the filter cartridge 2.

In this embodiment, there are two locking portions for the gripping member 301 and the mounting member 302, respectively. First, the gripping member 301 is located at a position where it is arranged on the first central axis 314 which is the same as the opening direction of the opening 312. There is, and a first locking portion 313 with a pair of substantially L-shaped mounting members is provided at the tip thereof, which has a convex shape toward the mounting member 302. Further, the mounting member 302 is provided with a notched groove-shaped first locked portion 322 that fits with the first locking portion 313. Further, the gripping member 301 is provided with a second locking portion 316 having the same shape as the first locking portion 313 and arranged on a second central axis 317 different from the opening direction of the opening 312. .. Similarly, the mounting member 302 is provided with a notched groove-shaped second locked portion 323 that fits with the second locking portion 316 material.

In the first grip portion 305 on the upper side, a pair of substantially L-shaped first locking portions 313 and a second locking portion 316 are notches in the mounting member 302 from above the mounting member 302, respectively. It is fitted into the groove-shaped first locked portion 322 and the second locked portion 323, and is engaged with the mounting member 302. Similarly, in the second grip portion 306 on the lower side, a pair of substantially L-shaped locking portions are formed in the shape of two notched grooves in the mounting member 302 from below the mounting member 302. It is fitted to the locked portion and engaged with the mounting member 302. The mounting member 302 is fastened and fixed to the wall surface with two screws 304. By engaging the gripping member 301 and the mounting member 302 at two locking portions in this way, these two parts are stably fixed without wobbling, and the filter cartridge 2 can be firmly held in normal times. Further, when the filter cartridge 2 is replaced, it can be easily attached and detached. The gripping member 301 and the mounting member 302 may be fixed by any means such as screw fastening or claw fitting.

The columnar filter cartridge 2 is inserted through the openings 312 of the two gripping members 301, and the shapes of the two gripping members 301 fit each other firmly, and the elastic force of the gripping members allows the gripping members to be gripped securely without loosening. Further, the distance D between the outer ends of the first grip portion 305 and the second grip portion 306 shown in FIG. 4 is 0.35 Lf or more and 0.9 Lf or less with respect to the total length Lf of the filter cartridge 2 shown in FIG. desirable. If the distance D is 0.35 Lf or more, even if the filter cartridge has a long overall length, if the distance D that can be stably gripped is 0.9 Lf or less, even if the filter cartridge is moved in the longitudinal direction thereof. It is possible to prevent the filter cartridge 2 from falling off. If the width of the portion of the gripping member 301 that grips the filter cartridge is sufficiently wide, only one gripping member 301 is engaged with the mounting member 302, and the filter cartridge 2 is gripped by only one gripping member 301. It may be in the form.

In the embodiments of FIGS. 1 and 2, since the insertion direction of the filter cartridge 2 into the opening of the gripping member 301 is the direction perpendicular to the wall surface, the filter cartridge 2 is attached to the inner side wall of the limited space below the kitchen sink. However, the filter cartridge 2 can be easily attached and detached by inserting the hand straight.

As the material of the gripping member 301 and the mounting member 302, resins such as ABS resin, polycarbonate, polystyrene and polypropylene, and metals such as stainless steel, brass and bronze can be used. Among these, manufacturing ABS resin or polypropylene having a good appearance by injection molding has merits in terms of appearance and manufacturing cost, and has a merit that the filter cartridge 2 can be easily attached and detached.

FIG. 3 is a perspective view showing an example of a water purifier attached to a water purifier holder. The water purifier 1 includes a filter cartridge 2 containing a filter medium, a bottom lid 201 for closing the lower end opening of the filter body 82, a raw water introduction pipe 7, and a water purification outlet pipe 8, and is for a water purifier to which the filter cartridge 2 can be attached and detached. It is composed of a filter head 3. The raw water introduction pipe 7 of the water purifier filter head 3 and the water purification outlet pipe 8 are connected to a water purifier faucet (not shown) in the kitchen. When the water purifier faucet is opened by turning the lever or the like, tap water is supplied to the raw water introduction pipe 7 from the valve mechanism built in the water purifier faucet. The purified water purified by the water purifier 1 returns from the water purification outlet pipe 8 to the water purifier faucet, and is discharged as it is from the discharge port of the water purifier faucet without passing through the valve mechanism. That is, the water purifier 1 is provided on the downstream side of the valve mechanism built in the water purifier faucet so that the water pressure is not applied to the water purifier 1 when the water is stopped. It is a so-called type II water purifier. However, the water purifier 1 of the present invention is not limited to the type II. It may be used as a so-called I-type water purifier in which water pressure is applied to the water purifier 1 when the water is stopped.

FIG. 4 is a perspective view of an example installed in the upper right corner (not shown) of the storage space under the sink in the kitchen. By inverting the left and right sides of the water purifier holder 300, it can also be installed in the upper left corner (not shown) of the storage space under the kitchen sink. The filter cartridge 2 is installed horizontally with respect to the vertical installation of the filter cartridge 2 in FIG. 1. The angle (acute angle) formed by the insertion direction of the filter cartridge 2 into the opening 312 of the gripping member 301 and the direction perpendicular to the wall surface is preferably 10 degrees or more and 90 degrees or less. If the angle is 10 degrees or more, for example, when there is an obstacle in the front direction of the gripping member 301, or when the upper right corner or the upper left corner of the storage space under the kitchen sink is narrow, the filter cartridge 2 is installed laterally. Even if it cannot be attached or detached, the filter cartridge 2 can be replaced from an oblique direction avoiding the kitchen sink. Further, since the insertion direction of the filter cartridge 2 is the direction in which the angle is the largest along the wall surface, the angle is naturally 90 degrees or less. Further, since the weight of the filter cartridge 2 is applied downward, it can be removed with a smaller force than in the case of vertical mounting. Further, the removing force F of the filter cartridge 2 is preferably 0.5 M kilogram weight or more and 2.0 M kilogram weight or less with respect to the weight M kilogram of the filter cartridge when it is full. When the removing force F is 0.5 M kilogram-force or more, the filter cartridge 2 can be prevented from falling off. When the removing force F is 2.0 M kilogram-force or less, the filter cartridge 2 can be removed with an appropriate force.
In the form of FIG. 4, the gripping member 301 is attached to the mounting member 302 so that the insertion direction of the filter cartridge 2 into the opening 312 is 45 degrees downward with respect to the direction perpendicular to the wall surface.

FIG. 5 is a side view when the gripping member 301 is attached so that the insertion direction of the filter cartridge 2 into the opening 312 is 45 degrees downward with respect to the direction perpendicular to the wall surface. Hereinafter, in a state where the gripping member 301 is gripping the filter cartridge 2, the direction in which the central axis of the cylinder of the filter cartridge 2 faces is the central axis direction, and the gripping member with respect to the mounting member 302 in the embodiments of FIGS. The direction in which the 301 is engaged will be described as the first direction. The gripping member 301 is engaged with and attached to the mounting member 302 in a second direction in which the central axial direction is reversed from the first direction. The first locking portion 313 of the gripping member 301 faces diagonally upward and engages with the second locked portion 323 of the mounting member 302, and the second locking portion 316 faces horizontally on the wall surface. It is engaged with the first locked portion 322 of the mounting member 302 so as to be vertically attached to the mounting member 302. Since the first locking portion 313 is arranged on the first central axis 314 which is the same as the opening direction of the opening 312, the opening direction of the opening 312 of the gripping member 301 is obliquely downward depending on this engagement method. Can be. In this way, by simply reversing the engagement direction of the gripping member 301 with respect to the mounting member 302, the gripping member 301 with respect to the wall surface is equal to the difference in angle between the first central axis 314 and the second central axis 317. The angle of the opening 312 in the opening direction can be changed. That is, the water purifier holder 300 can change the opening direction angle of the opening 312 of the gripping member 301 with respect to the wall in two ways depending on the mounting location, and as a result, the filter cartridge 2 can be easily replaced.

As a matter of course, the first locking portion 313 and the second locking portion 316 of the gripping member 301, and the first locked portion 322 and the second locked portion 323 of the mounting member 302 are When the gripping member 301 is engaged with the mounting member 302 in the first direction, the first locking portion 313 and the first locked portion 322 can be engaged with each other, and the second engaging member 301 can be engaged. When the stop portion 316 and the second locked portion 323 can be engaged and the gripping member 301 is engaged with the mounting member 302 in the second direction, the first locking portion 313 and the second locking portion 313 are engaged. The shape is such that the second locked portion 323 can be engaged with the second locked portion 316 and the first locked portion 322 can be engaged with the second locked portion 316. Further, the first locking portion 313 and the second locking portion 316 may have a notched groove shape, and the first locked portion 322 and the second locked portion 323 may have a convex shape.

If the gripping member 301 and the mounting member 302 are engaged with each other at two locking portions, these two parts are stably fixed, but in order to further increase the stability, the first locking is performed. Another locking portion is provided between the portion and the second locking portion, and another locked portion is provided between the first locked portion and the second locked portion. It may be possible to engage.

FIG. 7 is a perspective view showing an example of a method of assembling the gripping member 301 on the mounting member 302. As shown in FIG. 7, the gripping member 301 is attached from the outside in the longitudinal direction of the attachment member 302. At that time, the reinforcing rib 315 of the gripping member 301 gets over the mounting rib 324 of the mounting member 302. As a result, after obtaining the feeling that the gripping member 301 has reached the mounting member 302, the gripping member 301 can be reliably mounted, and the gripping member 301 does not easily fall off from the mounting member 302.

Further, in order to perform the filter cartridge replacement work in the space under the sink with better workability, the insertion direction of the filter cartridge 2 into the opening 312 of the gripping member 301 in the state of being engaged in the first direction. The angle (acute angle) formed by the insertion direction of the filter cartridge 2 into the opening 312 of the gripping member 301 in the state of being engaged in the second direction is preferably 10 degrees or more and 90 degrees or less. If the angle is 10 degrees or more, the insertion direction of the filter cartridge 2 can be sufficiently changed. Therefore, for example, in the state of being engaged in the first direction, the filter cartridge is caused by an obstacle in the storage space under the kitchen sink. Even when the filter cartridge 2 cannot be inserted, the filter cartridge 2 can be inserted while avoiding obstacles by engaging in the second direction. Further, since the insertion direction of the filter cartridge 2 is often perpendicular to the wall surface under the kitchen sink, for example, the insertion direction of the filter cartridge 2 is relative to the wall surface in the state of being engaged in the first direction. In the case of being vertical, the insertion direction of the filter cartridge 2 in the state of being naturally engaged in the second direction is the direction in which the angle is the largest along the wall surface, so the angle is preferably 90 degrees or less. .. Since the stored items are often placed in the lower direction of the storage portion at the lower part of the kitchen sink, the angle is more preferably 60 degrees or less.

Further, the gripping member has a plurality of reinforcing ribs 315 protruding in the radial direction. The reinforcing ribs 315 that hit the mounting members on the outside of the two convex shapes are also effective as reinforcing ribs for improving the strength of the base of the gripping member because the gripping member 301 having a substantially C shape firmly grips the filter cartridge 2. Is raising.

Further, if the mounting member is provided with opening holes at two places, a binding band, a hook-and-loop fastener, a binding string, etc. are passed through the opening holes, and the filter cartridge is wound and tied, the filter cartridge is held and fixed more reliably. be able to.

The means for fixing the mounting member of the water purifier holder to the wall of the space under the sink may be screw tightening or strong double-sided tape.

Finally, an example of how to replace the filter cartridge 2 of the water purifier 1 will be described.
When the filter cartridge 2 of the water purifier in the present invention is attached or detached, if the filter cartridge 2 is turned 90 degrees counterclockwise, the filter cartridge 2 is easily removed from the water purifier filter head 3 by the bayonet mechanism.

Next, the unused filter cartridge 2 is attached to the water purifier filter head 3. When the tip of the unused filter cartridge 2 is inserted into the water purifier filter head 3, the central axis of the filter cartridge 2 naturally aligns with the central axis of the water purifier filter head 3. When the unused filter cartridge 2 is turned 90 degrees clockwise after getting the feeling of reaching the water purifier filter head 3, the unused filter cartridge 2 can be securely attached to the water purifier filter head 3.

The present invention relates to a holder for installing a water purifier for purifying tap water in a space under a sink in a kitchen, and more particularly to a holder for an undersink type water purifier, which is a wall-mounted water purifier or a stand-type water purifier. It can be applied to all water purifiers. It is not limited to the undersink type water purifier.
