The present invention relates to a water purification device having a function of purifying tap water supplied to a general house or the like from a water supply facility.

In recent years, in order to eliminate the harmful effects of impurities, such as chlorine contained in the tap water supplied to general houses, the water purification apparatus which can be used in a bathroom, a washroom, etc. has been developed. As a conventional water purifier, there are some in which a filter medium such as activated carbon or ceramics is filled into a filter medium container in a state of being in close contact and formed (for example, see Patent Documents 1 and 2). When such a water purifying device is disposed in a hot water supply pipe such as a bathroom, impurities such as chlorine are adsorbed and filtered when the tap water passes through the water purifier, thereby obtaining clean tap water.

[Patent Document 2] Japanese Patent Application Laid-Open No. 2001-314340

The "water purifier for bathroom" described in Patent Literature 1 is used to connect a connection hose connected to a faucet installed in a bathroom, and a shower hose or a water supply hose. It is hard to use in small place and may be disturbed during use.

On the other hand, since the "water purification shower device" described in Patent Literature 2 can be attached to the water purification unit on the wall surface of the bathroom, it is not necessary to place it on the bottom surface of the bathroom or the like as the "water purification device for the bathroom" described in Patent Literature 1, It is not disturbed during use. However, since the purified water part is exposed, hot water, cold water, or foam of shampoo or soap, which is stuck in the middle of a shower or the like, tends to remain on the outer surface of the purified water part, and it becomes a contaminant that does not drop well for a long period of time, or causes mold. There is a thing to do.

In addition, if the purified water portion is accidentally pulled out of the wall during use, the dropped purified water portion may collide with the bottom surface or be damaged, or it may hit the user and cause pain. In addition, when hot water is supplied to a bathtub using hot water purified by a water purifier, there is a risk of burns when the user comes into contact with the purified water part that has been heated by passing relatively high temperature hot water for a long time.

The problem to be solved by the present invention is that it can be easily used even in a relatively narrow place, and contaminants do not stick well, and do not fall or suffer water purifier even if it accidentally falls off or touches the body. The present invention provides a water purifier excellent in safety.

The water purifying apparatus of the present invention includes a water purifier having a water inlet and an outlet, a casing for detachably accommodating the water purifier in a state in which the water inlet and the water outlet are exposed, and the casing on the wall for detachably attaching the casing to a wall. A fixed holding member is provided, and the outer surface of the casing is formed into a smooth continuous curved surface.

With such a configuration, since the water purifying device can be used in a state fixed to the wall, it can be easily used even in a relatively narrow place. Since the outer surface of the casing housing the water purifier is formed with a smooth continuous curved surface, contaminants do not stick well even when a shower or shampoo foam is splashed on it, and the water purifier is damaged or pained even if it accidentally falls off or contacts the body. I do not accept it. In addition, since the water purifier is housed in the casing, the user does not directly contact the water purifier, which has become hot due to passage of hot water for a long time, and is excellent in safety.

Here, the water purifier includes a cylindrical filter medium container filled with a granular filter material flowably, an inlet provided at one end in the axial direction of the filter medium container to introduce water into the filter medium container, and introduced into the filter medium container. An outlet provided at the other end in the axial direction of the filter medium container for discharging water, and water introduced from the water inlet in order to flow in the filter medium container while drawing a spiral flow toward the water outlet; It is preferable to have a helical frequency portion provided.

With such a configuration, the tap water introduced from the inlet port flows along with the granular filter medium along the channel portion of the inner circumferential surface of the filter medium container while drawing a spiral flow, and at this time, the water and the granular filter medium are continuously contacted with vigorous stirring, so that the tap water Chlorine, impurities, and the like contained can be efficiently adsorbed and removed. In addition, since the granular filter medium flows while drawing a spiral flow with water, the surface of the granular filter medium contacts the water evenly, so that a "water path (part through which water always passes)" is not formed. For this reason, the excellent water purification function can be maintained for a relatively long time.

Moreover, it is preferable to arrange | position so that the said water inlet and said water outlet may be mirror-symmetric by making the surface orthogonal to the said shaft center in the center of the axial center direction of the said filter medium container symmetrical plane. In such a configuration, since the inlet and the outlet are symmetrical with a symmetrical surface interposed therebetween, the function of the inlet and the outlet is reversed to introduce water from the outlet and discharge the water from the outlet. It is also possible to arrange the water inlet and outlet according to the installation place. In addition, contrary to the usual use method, when the water is fed in from the outlet and discharged from the inlet, the particulate filter medium in the filter medium container can be washed (backwashed) in order to generate backflow in the filter medium container.

On the other hand, there is provided a diffusion means for guiding the water introduced from the water inlet in the radial direction of the filter medium container in a radial direction, and between the water inlet and the diffusion means to provide a diffusion chamber having an enlarged shape toward the diffusion means. desirable.

With such a configuration, the water introduced from the water inlet collides with the diffusion means entirely while diffusing in the diffusion chamber of the shape enlarged toward the diffusion means, so that the water flows into the filter medium container so that the water is evenly distributed throughout the granular filter medium. Therefore, the filtration efficiency is improved, and the number of purification treatments can be increased.

Further, as the diffusion means, a water receiving surface in which water introduced from the water inlet contacts, a plurality of water passing holes arranged at equal intervals around the water surface, and the water passing holes adjacent from the water receiving surface A diffusion member having a protrusion formed radially toward the inner circumferential surface of the filter medium container can be provided via the gap.

With this configuration, the water introduced from the water inlet is in contact with the water surface, and then radially diffuses along the radially formed protrusion, and passes through the plurality of water passages arranged around the water surface, and proceeds toward the particulate filter medium. Therefore, the filtration efficiency can be reliably improved while the structure is relatively simple. In addition, since the stiffness and strength of the diffusion member itself can be increased by having the projections formed radially, even if the inflow water pressure from the inlet is increased, it is hardly deformed, and it is possible to cope with an increase in the inflow water amount.

In addition, at least a portion of the casing may be coated with a sterilizing function. Such a structure can prevent mold from occurring on the outer surface or the inner surface of the casing or propagate various germs, so that it can be kept clean for a long time.

It is a figure which shows the inner surface side of a frequency cap.

The casing 11 which comprises the water purification unit 10a shown in FIG. 4, FIG. 5 is formed with the upper casing 11a shown in FIG. 9, and the lower casing 11b shown in FIG. Both the upper casing 11a and the lower casing 11b have a ship shape such as cutting a rugby ball into a plane including its axis. As shown in FIG. 9, the inside of the upper casing 11a is provided with the cavity which can accommodate the upper half of the water purifier 13. As shown in FIG. As shown in Fig. 10, through holes 11c for projecting the water inlet 13v and the water outlet 13w of the water purifier 13 are provided in the left and right portions inside the lower casing 11b, respectively. A plurality of ribs 11e for holding the left and right portions of the water purifier 13 are formed in the portion near the center than the hole 11c, and for fixing the water purifier 13 in the portion near the center than the rib 11e. An approximately cylindrical protrusion 11d is provided.

The water purifier 13 is placed on the rib 11e in the lower casing 11b in such a manner that the water inlet 13v and the water outlet 13w of the water purifier 13 respectively protrude from the through holes 11c. When the upper casing 11a is put on to cover the lower casing 11b and the water purifier 13, and the peripheral edges 11g of the lower casing 11b and the upper casing 11a are joined to each other, the water purification unit shown in FIG. 10a is formed. At this time, as shown in FIG. 3, since the periphery edge part 11g of the lower casing 11b and the upper casing 11a form the uneven | corrugated fitting structure, the lower casing 11b and the upper casing 11a are connected. It can reliably join.

Next, based on FIGS. 11-18, the structure, function, etc. of the water purifier 13 (refer FIG. 3) accommodated in the water purification unit 10a which comprises the water purification apparatus 10 shown in FIG. 1 are demonstrated. FIG. 15 is a partially omitted cross-sectional view taken along line CC of FIG. 11, FIG. 16 is a view showing an open end of the filter medium container, FIG. 17 is a partially omitted cross-sectional view taken along line DD of FIG. 16, and FIG. Some omissions in cross section.

As shown in FIG. 11, FIG. 12, and FIG. 15, the water purifier 13 can be attached or detached to the cylindrical filter medium container 13a which incorporates the filter medium 16, and the opening part 13n of both ends of the filter medium container 13a, respectively. And a cap 13b attached thereto. The left and right frequency caps 13b have the same shape and have a structure in which the inlet port 13v (outlet port 13w) is protruded to the hemispherical body portion 13c in a direction orthogonal to the shaft center 13x. On the outer circumference of the filter medium container 13a, a reinforcing rib 13r shorter than the length in the axial center 13x direction is formed in parallel with the shaft center 13x, and is engaged at a position slightly away from both ends of the reinforcing rib 13r. 13s is provided. In addition, an engaging groove 13d bent in an L shape is provided on the inner circumferential surface of the opening 13m of the cap 13b.

Since the inner diameter of the opening 13m of the water cap 13b is slightly larger than the outer diameter of the opening 13n of the filter medium container 13a, the opening 13n of the filter medium container 13a is formed of the water cap 13b. It can be made to fit in the opening part 13m. Then, the engaging projection 13s of the outer periphery of the filter medium container 13a is inserted into the engaging groove 13d of the inner periphery of the opening 13m of the water cap 13b, and the filter medium container 13a or the water cap 13b. Is rotated clockwise, the engaging projection 13s is fitted into the inner portion of the engaging groove 13d, and the force cap 13b is detachably attached to the filter medium container 13a. At this time, since an adhesive agent is interposed between the cap 13b and the filter medium container 13a, both are firmly fixed.

As shown in FIG. 13, FIG. 14, the water inlet 13v of the frequency cap 13b is communicated in the hemispherical-shaped main-body part 13c, and the several inner side ribs 13e are formed in the inner surface of the main-body part 13c. Is radially formed. In addition, in FIG. 1, FIG. 11, etc., although the inlet 13v and the outlet 13w attach a different name and code | symbol, respectively, the frequency cap attached to the opening part 13n of the both ends of the filter medium container 13a ( Since 13b) is the same shape, the shape and function of the water inlet 13v and the water outlet 13w are also the same. For this reason, 13w can be used as a water inlet and 13v can be used as a water outlet as opposed to the case where FIGS. 1, 11, etc. show.

As shown in FIG. 15, the water purifier 13 is a cylindrical filter medium container 13a in which the granular filter medium 16 is fluidly filled, and the filter medium container 13a for introducing water into the filter medium container 13a. An inlet 13v provided at the other end in the axial center 13x direction of the outlet and a outlet port provided at the other end in the axial center 13x direction of the filter medium container 13a for discharging water introduced into the filter medium container 13a ( 13w) and the spiral shape provided in the inner peripheral surface 13f of the filter medium container 13a in order to flow the water introduced from the water inlet 13v, drawing a spiral flow toward the water outlet 13w in the filter medium container 13a. The frequency unit 15 is provided. In the present embodiment, the particulate filter medium 16 having a volume of about 85 to 95% of the volume of the filter medium container 13a is filled, and the flow space S is provided in the filter medium container 13a to thereby form the inside of the filter medium container 13a. The fluidity of the granular filter medium 16 in Esau is secured.

Further, as a diffusion means for guiding the water introduced from the water inlet 13v radially in the circumferential direction of the filter medium container 13, a substantially disk-shaped diffusion member 14 is disposed on the opening 13m side, and the water inlet 13v is provided. Between the and the diffusion member 14, a diffusion chamber 17 of an enlarged shape toward the diffusion member is provided. In this embodiment, the inner side of the hemispherical cap 13b is the diffusion chamber 17.

As shown in Figs. 16-18, the diffusion member 14 is formed of the water receiving surface 14h formed around the shaft center 14c and the water receiving surface 14h so as to contact the water introduced from the water inlet 13v. Radial radially toward the inner circumferential surface 13f of the filter medium container 13a via a plurality of egg-shaped water passage holes 14a arranged at equal intervals around and between the water passage surfaces 14h and the adjacent water passage holes 14a. It has the formed protrusion 14d. A plurality of mesh bodies 14m are attached to the plurality of water passage holes 14a, respectively.

The ridgeline 14e of the protruding portion 14d has a linear shape, and an inclined surface 14f that forms a downhill gradient toward the inner circumferential surface 13f of the filter medium container 13a is provided at the tip of each protruding portion 14d. These inclined surfaces 14f are disposed at positions away from the inner circumferential surface 13f of the filter medium container 13a. In the region between the water receiving surface 14h and the water passage 14a, a smooth inclined curved surface 14g is formed to make a downhill gradient toward the water passage 14a. As shown in FIG. 17, FIG. 18, the water receiving surface 14h, the protrusion part 14d, the inclined surface 14f, and the inclined curved surface 14g are formed in the both surfaces of the diffusion member 14. As shown in FIG.

As shown in FIG. 15, the water-repelling part 15 is formed in the spiral shelf shape which protruded toward the shaft center 13x from the inner peripheral surface 13f of the filter medium container 13a, and the diffusion member 14 by the water inlet 13v side. ) Is disposed so as to rotate the inner circumferential surface 13f of the filter medium container 13a between the water discharge port 13w and the diffusion member 14. In addition, when the shaft center 13x of the filter medium container 13a is kept horizontal, the one end 15a of the water supply part 15 is located in the lowest part of the diffusion member 14 by the side of the water inlet 13v, and the water outlet ( 13b) is arrange | positioned so that the other end 15b of the frequency part 15 may be located in the lowest part of the diffusion member 14 on the side.

As shown in FIG. 1, FIG. 2, when the water purifier 10 is attached to the wall surface W of a bathroom etc., and tap water is supplied from the water inlet 13v, the tap water will spread | diffuse 17 in the tap cap 13b. ) Flows in contact with the water receiving surface 14h of the diffusion member 14 while being diverted or diffused by the inner circumferential surface of the main body portion 13c and the plurality of power ribs 13e (see FIG. 14), After spreading radially toward the outer circumferential direction, the liquid flows through the plurality of water passage holes 14a and flows into the filter medium container 13a. The tap water which flowed into the filter medium container 13a flows toward the diffusion member 14 at the outlet port 13w while drawing a spiral flow along the water supply part 15 together with the granular filter medium 16. In this flow process, since the tap water and the granular filter medium 16 are in constant contact with vigorous stirring, chlorine or impurities contained in the tap water are adsorbed and removed by the granular filter medium 16.

The tap water which flowed in the filter medium container 13a together with the particulate filter medium 16 while drawing a spiral flow passed through the plurality of water passage holes 14a of the diffusion member 14 on the outlet port 13w side, and then the water cap ( It converges by the inner peripheral surface of the main-body part 13c of FIG. 13b, and the frequency rib 13e (refer FIG. 14), and is discharged as purified water from the water outlet 13w. In addition, as shown in FIG. 15, the water inlet 13v, the water outlet 13w, the diffusion chamber 17, and the diffusion member 14 which were provided in the right and left of the filter medium container 13a which comprises the water purifier 13 are filter media, respectively. Since it is arrange | positioned so that mirror symmetry may be carried out with the center surface 13y orthogonal to the center of the axial center 13x direction of the container 13a, 13w can also be used as a water inlet and 13v as a water outlet. Therefore, the water inlet and the water outlet can be arranged depending on the place of installation, and in contrast to the normal use state, the water is supplied from the water outlet 13w and the water is discharged from the water inlet 13v so as to discharge the water from the water inlet 13v. The granular filter medium 16 may be washed (backwashed).

As described above, the granular filter medium 16 in the filter medium container 13a flows while drawing a spiral flow with the tap water, so that all the granular filter medium 16 evenly contact with the tap water, so that a so-called "water path" is not formed. It can maintain a good water purification function for a long time.

Although the material, the property, etc. of the granular filter material 16 are not limited, In this embodiment, 75 mass% and 20 mass% of activated carbon (brand name) WH2C32 / 60LLSS and WHA28 / 48 by Enviro Chemical Co., Ltd., respectively, When a mixture of 5% by mass of alumina-silica-based ceramics manufactured by Sanes Industrial Co., Ltd. of the present applicant was used, chlorine, impurities, and the like in tap water could be efficiently removed. In addition, since the ceramics also have a function of finely decomposing clusters of water molecules in tap water, the purified water obtained by passing the water purification device 10 is skin-friendly, soft, and has no smell. For this reason, it does not give a tingling feeling to a person of sensitive skin, an atopic constitution or an allergy constitution. Moreover, even if it is used for washing hair, there is no stiffness of the hair after washing the hair, and the effect such that the hot water of the bath does not get dirty easily is obtained.

Since the water purifier 10 can be used in a state fixed to the wall W, it can be used easily even in a relatively narrow place. Since the outer surface of the casing 11 accommodating the water purifier 13 is formed with a smooth continuous curved surface, contaminants are less likely to adhere even if a shower or foam of shampoo is splashed. Since the water purifier 13 is covered with the casing 11, the water purifier 13 may be damaged or suffered even if the water purifying unit 10a accidentally falls or the body comes into contact with the water purifying unit 10a. none. Moreover, since the water purifier 13 is accommodated in the casing 11, there is no possibility that a user directly contacts the water purifier 13 which became high temperature by the passage of hot water for a long time, and is also excellent in safety.

In addition, in order to guide the tap water introduced from the water inlet 13v radially in the circumferential direction of the filter medium container 13a, a diffusion member 14 is provided, and a diffusion member is provided between the water inlet 13v and the diffusion member 14. The diffusion chamber 17 of the shape expanded toward 14 is provided. Therefore, the tap water introduced from the water inlet 13v collides with the diffusion member 14 as a whole while diffusing in the diffusion chamber 17 having an enlarged shape toward the diffusion member 14 and flowing into the filter medium container 13a. Thus, the tap water is dispersed evenly toward the granular filter media 16 as a whole. For this reason, the filtration efficiency is high, and the amount of purified water can be increased compared to the conventional purification device.

In addition, the diffusion member 14 includes a water receiving surface 13h to which the tap water introduced from the water inlet 13v abuts, a plurality of water passage holes 14a arranged at equal intervals around the water receiving surface 13h, and the water receiving surface. A plurality of protrusions 14d are formed radially toward the inner circumferential surface 13f of the filter medium container 13a via the adjacent water passage holes 14a from 14h.

Therefore, the tap water flowing into the diffusion chamber 17 from the water inlet 13v contacts the water surface 14h, and then diffuses radially along the plurality of protrusions 14d, and is disposed around the water surface 14h. It progresses toward the granular filter medium 16 through the several through-holes 14a which were made. For this reason, while being a relatively simple structure, filtration efficiency can be improved reliably. In addition, since the stiffness and strength of the diffusion member 14 itself are improved by having the plurality of radially formed protrusions 14d, it is hardly deformed even if the inflow water pressure from the inlet 13v is increased. It can respond.

Furthermore, since the outer surface and the inner surface of the casing 11 (the surface in contact with the atmosphere) are coated with silver ions having a sterilizing function, the casing 11 may be formed with mold or multiply various germs. It can prevent and keep clean for a long time.

The water purification device of the present invention can be widely used as a constituent member of a hot water supply facility such as a bathroom or a kitchen of a general home or a barber shop, a beauty salon, a pet shop, and the like.

According to the present invention, it is possible to provide a water purifying device which can be easily used even in a relatively small place, and does not easily adhere to contaminants, and does not suffer from damage or pain even if it accidentally falls or the body comes into contact.
