 Specification

Water purifier technical field

 The present invention relates to a water purifier, and more particularly to a water purifier that is used directly connected to an outflow portion of water and that has a water treatment portion that filters water passing therethrough and a magnetic treatment portion that performs magnetic treatment. Background art

 As a water purifier that is used by directly connecting to the outlet of water, for example, a tap water faucet pipe, a magnetic treatment part in which tap water flowing from a water faucet pipe is subjected to magnetic treatment, and a magnetized water passing through the magnetic treatment part are magnetized. There is known a filter provided with a filter portion to be subjected to a filtration process (Japanese Patent Application Laid-Open No. 7-284776).

 The magnetic processing unit of the water purifier includes a yoke having a bottom formed of a magnetic material in a cylindrical shape having a plurality of holes for allowing tap water to pass therethrough, and an annular magnet disposed at the center of the yoke. It is provided with. The yoke and the magnet are connected by rivets. The toroidal magnet is magnetized so that the two circular sides are the north and south poles.

 The tap water that has flowed into the water purifier first passes through the magnetic processing unit, is subjected to magnetic treatment, and then passes through the filter unit to be filtered. As described above, since the water purifier is provided with the magnetic processing unit, magnetic water that has been subjected to the magnetic treatment and the filtration treatment can always be obtained from the water purifier.

 On the other hand, as a water purifier used directly connected to a tap water faucet pipe, a water purifier equipped with a water purifier filled with a filtering material and having a structure capable of switching a flow direction of tap water in the water purifier is known. (Patent No. 2024557).

The water purifier has a substantially cylindrical body attached to a tap water faucet pipe, A water purification cylinder for purifying tap water passing therethrough, and a substantially cylindrical valve body that fits into the inside of the main body portion from a side surface of the main body portion. The water purifying cylinder has a projection formed so as to project from a side portion, and the projection is integrally fixed to the valve pair. Two flow passages are formed inside the protruding portion to communicate the valve body and the purifying cylinder.

 The valve element has a tap water inlet port for guiding tap water flowing into the main body to the first flow path in the protrusion, and a second flow path in the protrusion for purifying the tap water that has passed through the purification column and has been purified. And a purified water outlet port for guiding water to the tap water outlet port.

 The valve body, the projection, and the purifying cylinder, which are integrally fixed, are rotatably attached to the main body. When the purifying cylinder is rotated by a predetermined angle, the tap water inlet port of the main body communicates with the second flow path, and the purified water outlet port communicates with the first flow path. Therefore, when the purifier is rotated by a predetermined angle with respect to the main body, the tap water flows backward in the purifier.

 As described above, the water purifier is configured such that the direction of water flow in the purification column can be switched, so that clogging of the filter material in the purification column can be discharged by backflowing tap water.

By the way, tap water contains chlorine having a bactericidal effect, but chlorine is removed from the tap water that has passed through the filter section of the water purifier provided with the magnetic treatment section. Then, when not using water purifier for a long time, since the _c chlorine-free magnetized water at the bottom of the filter unit accumulates, if when the bacteria are bred in the filter unit occurs in the filter unit, the tap water containing bacteria There was a problem of being discharged from the water purifier.

In addition, the magnetic processing unit of the water purifier equipped with the magnetic processing unit is configured such that the tap water passes through a magnetic passage formed between the disc-shaped magnet and the yoke, so that the water is magnetically dispersed. At this time, the magnetic flux of the magnet leaks to the outside at this time, so that the magnetic flux is not effectively used or adversely affects external devices (for example, a pacemaker). There was a problem that the sound could be affected.

 In addition, a water purifier that can switch the flow direction of tap water in the water purification cylinder switches the flow direction of the tap water and reverses the flow through the filter medium, thereby discharging the attached matter to the filter medium. By reducing clogging, it is possible to extend the replacement time of the filter medium. Even if the replacement time is extended, it is still necessary to replace the filter medium in a short period of time, for example, three months, and there is a problem that the user has to replace the filter medium and burden the running cost.

 SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to suppress the occurrence of various bacteria in a water purifier used directly in connection with a water outflow side, and to effectively use tap water in a magnetic processing unit. An object of the present invention is to provide a water purifier that performs magnetic treatment, prevents magnetic flux leakage to the outside, and does not require time and effort to maintain use of the water purifier.

It is preferable that they are arranged so as to be located on the upstream side. With this configuration, the water that has flowed into the water purification section passes through the filtration section and is filtered, and the filtered water passes through the magnetic processing section and is magnetically processed. Further, by switching the flow path, the water flowing into the water purification section passes through the magnetic processing section and is magnetically treated, and the magnetically treated water passes through the filtration processing section and is filtered.

 Therefore, magnetized water can be obtained effectively by subjecting the filtered water to magnetic treatment. Also, even if germs are generated in the filtration unit, the bacteria are sterilized by the magnetic processing unit, so that the user can use the water discharged from the water purifier with confidence.

 In addition, the magnetized water that has been magnetically treated by switching the flow path is used to pass through the filtration unit, thereby forcibly discharging adhering matter into the filtration unit by the water flow of the magnetized water, and Thus, the deposit can be dissolved and effectively discharged to the outside. As a result, it is possible to prevent a decrease in the filtration capacity of the filtration unit, and it is possible to extend the replacement time of the filtration material. In addition, the magnetic processing unit is located upstream of the filtration unit when the flow path in the water purification unit is in the forward direction, and is located above the filtration unit when the flow path in the water purification unit is in the reverse direction. It is preferable that they are arranged so as to be located on the downstream side. With such a configuration, water sterilized by the magnetic processing unit passes through the filtration processing unit, so that it is possible to suppress the generation of various bacteria in the filtration processing unit.

Further, the water purification unit is provided with a plurality of the magnetic processing units, It is preferable that the filter is disposed so as to be located on the upstream side and the downstream side of the filtration section when the flow path in the water purification section is in the forward direction and the reverse direction.

The ball 35 is elastically urged by the spring 36 and is fitted into the recess 11 e of the casing 11.

 Therefore, every time the valve body 30 rotates by an angle of about 90 °, the pole 35 is fitted into each of the recesses 1 1 e, so that the user can confirm the rotation angle of the valve body 30. .

The cartridge 40 is equipped with a cylindrical multi-stage filter and can be replaced. It is possible. The filter is filled with a filtering material such as activated carbon, ceramic, or hollow fiber. In addition, the cartridge 40 shown in FIG. 2 has a flow path in which tap water enters the inside of the filter from the outer peripheral portion (the inlet 40a) of the annular filter and reaches a cylindrical passage provided inside the filter. I have. The configuration of the power cartridge 40 is not limited to the above configuration, and the upper and lower ends may be configured to have tap water inlet and outlet.

 As shown in FIG. 4, the magnetic processing unit 50 includes a case 51 made of a synthetic resin, two magnets (neodymium ferrite boron magnets) 52 arranged in the case 51 with opposite polarities, and A yoke 54 made of steel (SS400) for holding a stone 52 and a tubular pipe 56 made of a non-magnetic material and sandwiched between two arrow-shaped 4 dog magnets are provided.

And is housed.

Since the water purifier of the present embodiment is configured as described above, when the water purification unit 20 is rotated around the axis of the valve body 30, the valve body 30 is driven by the storage case 21, and the valve body 30 is moved. It rotates along the inner peripheral surface of the casing 11. When the water purification section 20 and the valve body 30 are rotated to the angular positions shown in FIGS. 1 and 2, the balls 35 of the valve body 30 are fitted into the recesses 1 1 e of the casing 11 and the valve body 30 are rotated. At the same axial position, the first flow path 31 matches and communicates with the tap water inlet port 1 la of the casing 11, and the second flow path 32 is the purified water of the casing 11 Communicate with exit port 1 1 _C.

 Therefore, when the flow path in the water purification section 20 is in the forward direction as shown in FIG. 2, the tap water from the tap water pipe 1 receives the tap water inlet port 11a, the first flow path 31, the flow path 24a, and The liquid is guided to the internal flow path 21 a of the storage case 21 and enters the inlet 40 a of the cartridge 40. Then, the tap water flowing into the flow path in the cartridge 40 is filtered by the filter, and then flows into the magnetic processing unit 50.

The purified water that has flowed into the magnetic processing unit 50 passes through the flow path in the magnetic processing unit 50, After being subjected to gas treatment, it is discharged from the outlet 50b of the magnetic processing unit 50. The magnetized water discharged from the magnetic processing unit 50 passes through the internal flow path 22a, is guided to the purified water outlet port "1 1c" through the flow path 24b, and the second flow path 32. It is discharged from the central hole 15b of 5.

 As described above, in the water purifier S, the tap water first removes unnecessary components by passing through the cartridge 40, and the purified water passes through the magnetic processing unit 50, so that an aggregate of water molecules ( The magnetic treatment effect is effectively exerted on the clusters, and the clusters are decomposed to obtain finely divided magnetized water.

 Furthermore, as shown in Fig. 8, when the water purification section 20 is rotated by an angle of approximately 90 ° from the angular position of Fig. 1 and is in a side-down state, the valve 30 also rotates by an angle of 90 ° from the angular position of Fig. 1. I do. At this time, the ball 35 of the valve body 30 is fitted into the recess 1 1 e of the casing 11, and the third flow path 33 of the valve body 30 matches and communicates with the tap water inlet port 1 la of the casing 11. .

 Accordingly, in this state, the tap water from the tap tap pipe 1 passes through the tap water inlet port 11a and the third flow path 33, is led to the tap water outlet port 11 of the casing 11, and is showered. It is discharged from the small hole 15a of the head 15. That is, in this state, the tap water from the tap water faucet pipe 1 can be discharged as it is without passing through the water purification section 20.

Further, when the water purification unit 20 is further rotated by an angle of approximately 90 ° from the state of FIG. 8 and is rotated through an angle of approximately 180 ° from the angular position of FIG. 1, the water purification unit 20 is completely overturned. In this case, it fitted into the ball 35 cliff one Thing 1 ¹ of the recesses 1 1 e of the valve body 30, opposite to the angular position of FIG. 2, the second flow path 32 is tap water of the casing 1 1 of the valve element 30 The first flow passage 31 communicates with the inlet port 11a, and the purified water outlet port 11c of the casing 11 communicates.

Therefore, when the flow path in the water purification unit 20 is in the opposite direction, the tap water from the tap water pipe 1 flows through the tap water inlet port M la, the second flow path 32, and the flow path 24b. The liquid is guided to the internal flow path 22a of the storage case 22, enters the flow path in the magnetic processing unit 50 from the outlet 50b, is magnetically processed, is further filtered through the flow path in the cartridge 40, and is then filtered. Emitted from 40A. Further, the tap water passes through the internal flow path 21a of the storage case 21 and is guided to the purified water outlet port 11c through the flow path 24a and the first flow path 31, and the central hole 15b of the shower head 15 is formed. Is discharged from

 In this way, the water purifier S of the present embodiment can reverse the tap water from the tap water faucet pipe 1 in the water purifier 20 by inverting the water purifier 20. Therefore, when the inside of the water purification section 20 is contaminated with tap water dirt, iron or water algae, the tap water from the tap water faucet pipe 1 is caused to flow back inside the water purification section 20, and the tap water is returned by the back-flowed tap water. The water purification unit 20 can be washed by discharging water dust, iron 鲭 or algae.

 Therefore, in the water purifier S, the valve 30 can be simultaneously rotated by rotating the water purification section 20, and the flow path of the tap water can be switched by the valve 30, and the tap water can be switched by the filter medium of the cartridge 40. Can be purified. Further, tap water from the tap water faucet pipe 1 can be discharged as it is without passing through the water purification section 20. Further, the tap water can be flowed back into the water purification section 20, thereby washing the water purification section 20.

Next, the magnetic processing unit 50 of this embodiment will be described in detail. In the water purifier equipped with the conventional magnetic treatment device, there is no configuration that effectively uses the magnetism of the magnet for the magnetic treatment and no configuration that leaks the magnetism to the outside. As described above, these are realized by the configuration of the magnet 52 and the yoke 54 and the like. FIG. 4 is a longitudinal sectional view of the magnetic processing unit 50, and FIG. 5 is a front view. As shown in these figures, the yoke 54 of the magnetic processing unit 50 has two opposing arms 54a, 54a on which the rectangular magnets 52 are mounted on the inner surface, a connecting portion 54b connecting these arms, and an inner side of the arm 54a. And four step portions 54c formed so as to sandwich the respective magnets 52. The rectangular magnets 52 having the same shape are arranged between the step portions 54c in the respective arm portions 54a. At this time, the opposing surfaces of the two magnets 52 face each other. The magnet 52 and the yoke 54 are formed at the same height. In this example, the height is 1 Omm.

The magnet 52 of this embodiment is made of NdFeB (neodymium ferrite boron) and has the following characteristics: a residual magnetic flux density Br of 1.344 T, a holding force Hcb force of 008 kA / m, and a holding force Hcj force << 1024 kA. / m, maximum energy product BHm is 343 kJ / m ³ , Hk force << 101 9 kA / m, Hk / Hcj force 0.996, Bd force << 0.666 T, Hd force 516 kA / m. Figure 6 shows the hysteresis curve. FIG. 7 shows a test result obtained by measuring the surface magnetic flux density of a test piece of a magnet used as the magnet 52. As can be seen from Fig. 7, the surface magnetic flux densities of the multiple specimens are about 0.46 to 0.48T for both the N and S poles.

 Figure 5 shows the flow of magnetism with arrows. The magnetic field generated from the N pole of the left magnet 52 crosses the pipe 56, reaches the S pole of the right magnet 52, and further passes from the N pole of the magnet 52 through the right arm 54a and the connecting portion 54b to the left pole. It reaches the arm 54a and reaches the south pole of the magnet 52 on the left. As described above, the water purifier S of the present embodiment has a configuration in which the magnetism is not leaked to the outside by forming the magnetic closed loop.

 The thickness X of the magnet 52 is set to 4 mm, and the width is set to about 8 mm. When the magnet 52 is arranged in the arm 54a, the facing magnet 52 is separated by about 7 mm. In the yoke 54, the thickness Y of each arm 54a located outside the magnet 52 is set to 3.4 mm.

A pipe 56 is provided between the two magnets 52. The greater the flow rate of tap water across the magnetic field, the greater the efficiency of the magnetic treatment. The water purifier S of the present embodiment is configured so that the tap water entering the water purification section 20 is passed through a pipe 56 having a diameter of about 7 mm to increase the flow velocity, so that the tap water is efficiently magnetically treated. ing. Also, since the width of the magnet 52 is set to be larger than the width of the pipe 56, All tap water passing through the pump 56 is magnetically treated. FIG. 9 shows a change in magnetic flux density around the yoke 54 when the thickness X of the magnet 52 is 4 mm and the thickness Y of the yoke 54 is changed. Here, the ratio of the thickness Y to the thickness X is defined as a thickness ratio Z. The horizontal axis is the thickness ratio Z.

 Life is point, country is point a, is point 13, 〇 is point c, and X is change in magnetic flux density at point d. Here, as shown in Fig. 5, point A is the center of the facing magnet 52, point a is the surface of the N pole of the magnet 52, and point b is the outer surface of the left arm 54a at the position corresponding to the magnet 52. Point c is the outside surface of the connecting portion 54b, and point d is the outside of the center of the surface connecting the tips of the two arms 52.

 As is clear from Fig. 9, the magnetic flux density at point A takes a small value when the thickness ratio Z is small, becomes maximum when the thickness ratio Z is about 0.8, and gradually increases when the thickness ratio Z is further increased. Will decrease. At point A, when the thickness ratio Z is 0.0, the magnetic flux density is 0.2T. When the thickness ratio Z is about 0.8, the magnetic flux density doubles to about 0.45T.

 The change in magnetic flux density at point a has the same tendency as point A. However, when the thickness ratio Z is 0.0, the magnetic flux density is 0.395 T. << When the thickness ratio Z is about 0.8, the magnetic flux density is about 0.53 T. Does not.

 From the viewpoint of efficiently magnetically treating the tap water, it is a portion that has a large effect of magnetically treating the tap water substantially passing through the pipe 56 instead of the magnetic flux near the surface of the magnet 52 (point a). It is desirable to design the magnet 52 so that the magnetic flux at the central portion (point A) becomes large.

Therefore, by setting the thickness ratio Z to an appropriate value based on the point A, for example, if the thickness ratio Z is set to 0.2 to 1.2, a magnetic flux density of about 0.3T or more can be obtained at the point A. Can be. If the thickness ratio Z is 0.4 to 1.0, a magnetic flux density of about 0.35 T or more can be obtained at the point A. More desirably, if the thickness ratio Z is set to 0.6 to 1.0, it is possible to obtain a magnetic flux density of about 0.4T or more at the point A. it can.

 On the other hand, when the thickness ratio Z is small, the magnetic flux density at the points b, c, and d becomes large because the leakage flux from the magnet 52 increases, but when the thickness ratio Z increases, the magnetic flux density decreases rapidly, and the thickness ratio Z Approximately 0.8 stops at about 0.8 and falls to about 0.01 to 0.02T. FIG. 10 is an enlarged view of FIG. When the thickness ratio Z exceeds about 0.8, the magnetic flux density at points b and c keeps a substantially constant value, or increases more at the force d, which further decreases. The magnitude of the leakage magnetic flux at points b, c, and d decreases in the order of points b, d, and c when compared at a thickness ratio of about ZO.2. When the thickness ratio Z is about 0.2, a large leakage magnetic flux exceeding 0.1 T is generated at the point b.

 From the viewpoint of leakage of magnetic flux to the outside, it is desirable that the magnetic flux density at points b, c, and d be small. Therefore, by setting the thickness ratio Z to an appropriate value, for example, if the thickness ratio Z is set to 0.4 to 1.2, the magnetic flux density is suppressed to about 0.08T or less at points b, c, and d. be able to. If the thickness ratio Z is desirably 0.6-1.0, the magnetic flux density at points b, c and d can be suppressed to about 0.5 T or less. Further, if the thickness ratio Z is set to 0.7 to 0.9, the magnetic flux density at points b, c, and d can be suppressed to about 0.025T or less.

 As described above, in order to improve the magnetic processing efficiency and reduce the leakage magnetic flux to the outside, the thickness ratio Z is preferably set to 0.4 to 1.0. In this case, the magnetic flux density can give a magnetic flux of about 0.35T or more to the fluid in the tube 1, and the leakage magnetic flux can be suppressed to about 0.08T or less.

Preferably, the thickness ratio Z is set to 0.6 to 1.0. In this case, the magnetic flux density can give a magnetic flux of about 0.4T or more to the fluid in the tube 1, and the leakage magnetic flux can be suppressed to about 0.05T or less. More preferably, the thickness ratio Z is set to 0.7 to 0.9. In this case, the magnetic flux density can give a magnetic flux of about 0.4T or more to the fluid in the tube 1, and the leakage magnetic flux can be suppressed to about 0.025T or less. In the water purifier S of this embodiment, the thickness ratio Z is set to 0.85 (X = 4, Y = 3.4). In the water purifier S of the present embodiment, the actual measured values of the magnetic flux density at point ，, point a, point b, point (the outer surface of the right arm 54a), and point c are 0.445, 0.53T, 0.016T, 0.015T, 0.0063T.

 As described above, the water purifier S of the present embodiment is configured such that the magnet 52 is disposed facing the inside of the two arms 54a of the yoke 54, and the two arms 54a are connected by the connection 54b. , Forming a stable magnetic closed circuit. Then, by setting the thickness Y of the arm portion 54a to an appropriate value, a magnetic field having a magnetic flux density of about 0.4T (point A) is generated, and this magnetic field increases the flow velocity in the pipe 56 and passes the pipe. Since the treated tap water is magnetically treated, the tap water passing through the magnetic treatment section 50 can be effectively subjected to the magnetic treatment.

 In addition, the thickness Y of the arm portion 54a is set appropriately so as not to leak magnetism to the outside, so that the leakage magnetic flux of 0.025T or less is suppressed even at the surface of the yoke 54 at points b and c. Have been. Therefore, considering the distance between the user who uses the water purifier S and the water purifier S, the magnetic field hardly affects the user from the magnetic processing unit 50. S can be used. In general, it is known that the magnetic treatment of tap water can decompose and subdivide the clustered water molecular structure in tap water, thereby increasing the dissolving power and osmotic power of water. . For example, the effect of magnetic treatment is to increase the dissolving power of carbonates (calcium, magnesium, etc.) and other inorganic substances, and to improve the dissolution of organic compounds.

Experiments have also revealed that sterilization is performed simultaneously by magnetic treatment of water. Although the mechanism of sterilization is not clear, it is speculated that the magnetically treated magnetized water penetrates the sprout in bacterial cells because the molecular structure of the water becomes smaller, and the saturated sprout ruptures from the inside. I imagine that they would do it. In addition, when hydrogen bonds between water molecules are divided (subdivided) by receiving the energy of magnetism and far-infrared rays, gas ゃ dissolved oxygen and nitrogen are ejected, and bacteria are also ejected by the volume shrinkage phenomenon of water molecules. Conceivable. At this time, it is assumed that aerobic bacteria (such as bacteria that require oxygen for life support, common bacteria, and Escherichia coli) fall into an oxygen-deficient state and die.

 In addition, microorganisms affect the inherent vibration of the microorganisms themselves, which are electromagnetic waves such as magnetic field lines and far-infrared rays, which are highly sensitive, and affect the activities on the living body side. Microorganisms have a very small capacity to dissipate the body's heat, so it is supposed that far-infrared rays that are absorbed are greatly affected by being converted to heat.

 The results of a test of the bactericidal effect using the magnetic processing unit 50 of the present embodiment are shown below. In the test, the hot spring water was magnetically treated, and the viable cell count, E. coli reaction, and Legionella bacterial count in 550 ml of the hot spring water before and after the magnetic treatment were detected. Before magnetic treatment, they were 3.3 x 1 000 Zml, negative, and 3.0 x 1 000 (per 550 ml), respectively. After magnetic treatment, they were 0.11 X l OOOZm and negative, respectively. (Around 550 ήη）).

In another test of the bactericidal effect, magnetic treatment was performed by circulating the water in the reservoir. _C As a result, the detected value of the coliform bacteria before magnetic treatment was 2.00 xl 0 ^{1 Q} (per 50 ml). No power was detected at all 60 minutes after the start of the magnetic treatment. Thus, it was found that the magnetic treatment has a very effective bactericidal action.

 When the water purification section 20 of the water purifier S is at the angular position in FIG. 1, the tap water from the tap water faucet pipe 1 is guided to the internal flow path 21 a of the storage case 21 and enters the inlet 40 a of the cartridge 40. This tap water is unpurified tap water and contains chlorine, which has a bactericidal action. Therefore, even when the water purifier S is not used for a long time, no germs are generated or propagated in the tap water in the internal channel 21a.

In addition, the flow path from the internal flow path 22a to the purified water outlet port 11c is made of magnetized water that passes through the cartridge 40 and is further divided into clusters by the magnetic processing unit 50. It is then filled with sterilized tap water. Therefore, even when not used for a long time, propagation of various bacteria in the flow path from the internal flow path 22a to the purified water outlet port 11c can be suppressed.

 When the water purification unit 20 is not used for a long time, the water purification unit 20 may be rotated over an angle of approximately 180 ° from the angular position in FIG. In this case, the internal flow path 21a and the first flow path 31 communicate with the purified water outlet port 11c. At this time, tap water containing chlorine remains in the internal flow path 21a of the storage case 21, and the tap water containing chlorine can block invasion of various bacteria from the purified water outlet port 11c. However, there is no possibility that bacteria will enter the water purification section 20 and propagate.

 In addition, when the water purification section 20 is overturned, the second flow path 32 communicates with the tap water inlet port 11 a and is connected to the tap water faucet pipe 1. Therefore, various bacteria are blocked by the tap water from the tap water pipe 1.

 As described above, in the water purifier S of this embodiment, even if the water purifier S is not used for a long time, the bacteria can be prevented from growing in the water purification section 20. Can be prevented.

 Even if the bacteria are present in the cartridge 40, the tap water that has passed through the cartridge 40 is sterilized by the magnetic processing unit 50 located downstream of the cartridge 40. The user can use the tap water that has passed through the water purifier S with confidence.

 In the case of a normal cartridge type water purifier, it is desirable to replace the cartridge in about three months. However, in the water purifier S of the present embodiment, the replacement time of the cartridge 40 can be extended to about six months or more by periodically inverting the water purification unit 20 and reversing the water flow direction in the water purification unit 20. .

In other words, if the water purification section 20 is reversed and the flow path direction is switched, the water is magnetically treated by the magnetic treatment section 40, and the magnetically treated magnetized water is supplied to the cartridge. The water passes through 40 and is discharged out of the water purification section 20.

 Accordingly, the magnetized water, which has been subjected to magnetic treatment and has increased dissolving power and osmotic power, passes through the filter medium in the cartridge 40, so that the magnetized water becomes a filter medium that does not merely discharge the deposits in the cartridge 40. The adhering material can be dissolved and effectively discharged to the outside. As a result, clogging of the cartridge 40 occurs, and the use period of the force cartridge 40 can be extended.

 Next, FIGS. 11 and 12 show another embodiment. Note that the same members as those in the embodiment of FIG. 1 are denoted by the same reference numerals, and redundant description will be omitted. In this embodiment, a magnetic processing unit 50 disposed on the right side of the cartridge 40 via the cartridge 40 and the ring, an auxiliary member disposed on the right side of the magnetic processing unit 50 and integrally fixed to the magnetic processing unit 50 37 is arranged in the storage case 21. Since the auxiliary member 37 is fixed to the valve body 30 by the bolt 25, the cartridge 40, the magnetic processing unit 50, the auxiliary member 37, and the valve body 30 are integrated.

 Further, the holding capacity bar 21 is screwed and fixed to the thread groove of the casing 11, and the water purification section 20 including the cartridge 40, the magnetic processing section 50, and the auxiliary member 37 is moved by the rotation of the valve body 30. It can rotate within the bar 41. Further, a switching lever 61 is attached to a side surface of the casing 11 opposite to the housing case 21. The switching lever 61 is fitted and fixed to the tip of the valve body 30.

Further, in the water purifier S shown in FIG. 11, a tap water inlet port 11a, a tap water outlet port 11b and a purified water outlet port 11c are formed in the casing 11 and the first and second tap holes are formed in the valve body 30. The second and third flow paths 31, 32, and 33 are formed, and the space between the first and second flow paths 31, 32 and the third flow path 33 is sealed by the O-ring 34a as in the embodiment of FIG. It is. The first flow path 31 communicates with the radial flow path 37 a of the auxiliary member 37, is connected to the internal flow path 21 a of the storage cover 21, and communicates with the inlet 40 a of the cartridge 40. The second flow path 32 communicates with the axial flow path 37b and communicates with the outlet 50b of the magnetic processing unit 50. The mounting cover 12 is screwed into the thread groove of the casing 11, and the casing 11 and the tap water pipe 1 are mounted and connected by the mounting cover 12, as in the embodiment of FIG. 2. . Further, in this embodiment, a pole 35 and a spring 36 are provided on the casing 11, and the spring 36 is engaged with and supported by the flange 64 of the sleeve 63, and the plurality of recesses 1 e are formed at an angular interval of about 90 °. The pawl 35 is elastically urged by a spring 36 and is fitted into the recess 11 e of the valve body 30.

 Therefore, every time the valve body 30 rotates by an angle of about 90 °, the ball 35 of the casing 11 is fitted into each of the recesses 1 1 e, whereby the rotation angle of the valve body 30 can be confirmed. The sleeve 63 is bonded and fixed to the casing 11 with an adhesive. Further, the shower head 15 is screwed into the casing 11, and a large number of small holes 15 a are formed in the shower head 15.

 Therefore, in the water purifier S shown in FIG. 11, when the valve body 30 is operated and rotated by the switching lever 61, the cartridge 40 and the magnetic processing unit 50 are moved together with the valve body 30 and the switching lever 61 in the housing cover 21. Rotate. When the switching lever 61, the valve body 30, the cartridge 40 and the magnetic processing unit 50 are rotated to the angular positions shown in FIG. 11, the balls 35 of the casing 11 are fitted into the recesses 1 1 e of the valve body 30, At the same axial position of the valve body 30, the first flow path 31 is in communication with the tap water inlet port 1 la of the casing 11, and the second flow path 32 is connected to the tap water outlet port of the casing 11. Communicate according to 1 1 c. At this time, the flow path in the water purifier S is in the forward direction.

Therefore, tap water from the tap water pipe 1 passes through the tap water inlet port 11a, the first flow path 31, the radial flow path 54 of the auxiliary member 37, and is guided to the internal flow path 2la of the capacity bar 21. The cartridge enters the entrance 40a of the cartridge 40, passes through the inside of the cartridge 40, is subjected to a filtration process, passes through the inside of the magnetic processing unit 50, and is subjected to magnetic processing. Exit 50b. Then, the magnetic processing unit 50 The magnetized water subjected to the magnetic treatment in the above is guided to the second flow path 32 and the purified water outlet port 11c and discharged.

 When the switching lever 61, the valve body 30, the cartridge 40 and the magnetic processing unit 50 are rotated by 90 ° from the angular position shown in FIG. 11, the pole 35 of the casing 11 causes the recess 1 1 e of the valve body 30 to rotate. And the third flow path 33 of the valve element 30 is in communication with the tap water inlet port 1 la of the casing 11. Accordingly, the tap water from the tap water pipe 1 passes through the tap water inlet port 11a and the third flow path 33, is guided to the tap water outlet port 1lb of the casing 11, and is discharged.

 Further, when the switching lever 61, the valve element 30, the cartridge 40 and the magnetic processing unit 50 are rotated again by an angle of 90 °, and from the angular position in FIG. The pole 35 of the singing 1 1 is fitted into the recess 1 1 e of the valve body 30, and the second flow path 32 of the valve body 30 communicates with the tap water inlet port M la of the casing 11, and the first flow path 31 communicates with the purified water outlet port 1 1 c of casing 11. At this time, the flow path of the water purifier S is in the opposite direction.

 Accordingly, tap water from the tap water pipe 1 passes through the tap water inlet port 11a and the second flow path 32, enters the outlet 50b of the magnetic processing section 50, passes through the magnetic processing section 50, and further passes through the cartridge 40. After passing through the inside of the cartridge 40, it is discharged from the inlet 40 a of the cartridge 40. That is, the flow path of the tap water flowing through the cartridge 40 and the magnetic processing unit 50 is reversed from the state shown in FIG.

 Further, the tap water passes through the internal flow path 21 a of the capacity bar 21, passes through the radial flow path 37 a of the auxiliary member 37, is guided to the first flow path 31 and the purified water outlet port M 1 c, and is discharged. Is done. Therefore, when the inside of the cartridge 40 is contaminated with tap water dust, iron or water algae, the tap water of the tap water tap pipe is caused to flow back into the water purifying cylinder 38. The cartridge 40 is washed with the tap water flowing backward. Can be.

Similarly to the water purifier S shown in Fig. 1, if the water purifier S in Fig. 11 is not used for a long time and is left at the angular position shown in Fig. 11, tap water containing chlorine will be discharged. Diameter No germs can propagate because they remain in the counter flow path 37a and the internal flow path 21a. Further, since the inside of the flow path from the purified water outlet port 11c to the second flow path 32 is filled with magnetized water, it is possible to prevent the propagation of various bacteria. Also, even if germs are generated in the cartridge 40, the tap water that has passed through the cartridge 40 is sterilized by the magnetic processing unit 50, so that the user can use the water purifier S with confidence. .

 When not used for a long period of time, the switching lever 61, the valve body 30, the cartridge 40 and the magnetic processing unit 50 are rotated from the angular position shown in FIG. Is also good.

 In this case, in the auxiliary member 37 and the capacity bar 21, tap water containing chlorine stays in the radial flow path 37a and the internal flow path 21a, and various bacteria enter through the purified water outlet port 11c. Also, the bacteria are blocked by the chlorine in the tap water, and the bacteria do not enter the water purification section 20.

 In the above embodiment, the cartridge 40 is located on the upstream side of the magnetic processing unit 50 in the normal use state shown in FIGS. 1 and 11. The present invention is not limited to this, and the magnetic processing unit 50 may be configured to be located on the upstream side of the cartridge 40 in a normal use state of the water purifier S as shown in FIG.

 With this configuration, when the flow path in the water purifier S is in the forward direction, the tap water first passes through the magnetic treatment section 50 in the water purification section 20, and the tap water is subjected to the sterilization treatment together with the magnetic treatment. It is. Therefore, the tap water sterilized in the normal use state passes through the cartridge 40, so that the risk of bacteria growing on the cartridge 40 is reduced. When the flow path in the water purifier S is in the opposite direction, the deposits in the cartridge 40 are forcibly discharged.

Therefore, even if the water purifier S is configured as shown in FIG. 13, it is possible to effectively obtain tap water subjected to magnetic treatment, sterilization treatment, and filtration treatment, and prevent bacterial contamination of the cartridge 40. . Further, as shown in FIG. 14, the magnetic processing unit 50 may be configured to be located on the upstream side and the downstream side of the cartridge 40 in a normal use state of the water purifier S. With such a configuration, it is possible to further prevent the growth of various bacteria in the card judge 40 and extend the service life of the cartridge 40. Further, the tap water passes through the magnetic processing section 50 a plurality of times, so that the magnetic processing efficiency is further improved. Industrial applicability

 As described above, according to the water purifier of the present invention, the magnetic processing unit is provided inside, and in the magnetic processing unit, the magnets are arranged facing the inside of the two arms of the yoke, and the two arms are connected.

The magnetic processing action can be exerted efficiently.

 As a result, the user can use the magnetized water magnetized by the high magnetic processing action, and can use the water purifier of the present invention without worrying about the adverse effect on the external device due to the leakage magnetic flux. it can.

 Further, in the water purifier of the present invention, even when the water is not used for a long period of time, since the magnetized water that has been sterilized by the magnetic processing unit accumulates on the downstream side of the magnetic processing unit, bacteria may proliferate. Thus, bacterial contamination of the cartridge can be prevented. Further, even if germs are generated in the cartridge, the cartridge is sterilized by the magnetic processing unit, so that the user can use the water purifier of the present invention with confidence.

In the water purifier of the present invention, tap water that normally enters the water purification section first passes through the cartridge for filtration processing, and then passes through the magnetic processing section and is discharged to the outside of the water purification section. However, when the water purification section is reversed, the tap water that has entered the water purification section passes through the magnetic processing section, passes through the filtration cartridge, and is discharged outside the water purification section. You can make it.

 By inverting the water purification unit in this way, the magnetized water magnetically processed by the magnetic processing unit can flow into the cartridge having the filtering material. As a result, the water purifier of the present invention, like the conventional water purifier capable of switching the direction of the flow path in the water purification section, reverses the tap water to the cartridge having the filtering material, thereby preventing clogging in the power cartridge. It has the effect of preventing.

 Further, the water purifier of the present invention can effectively dissolve dirt and the like in the cartridge by magnetized water having passed through the magnetic processing section and discharge it to the outside by switching the flow path direction. As a result, it is possible to extend the replacement time of the cartridge in the water purification unit, and it is not necessary to maintain the use of the water purifier. In addition, by configuring the magnetic processing unit to be arranged on the upstream side of the cartridge in a normal use state, sterilized tap water flows into the power cartridge, so that generation of various bacteria in the cartridge is reduced. Can be deterred.

 In addition, by adopting a configuration in which the magnetic processing units are arranged on the upstream side and the downstream side of the cartridge, it is possible to suppress the occurrence of various germs in the cartridge and to extend the service life of the cartridge. it can.

 As described above, according to the present invention, the occurrence of various bacteria in the water purifier is suppressed, the tap water is effectively magnetically treated in the magnetic processing unit, the magnetic flux leaking to the outside is prevented, and the water purifier is prevented. It is possible to provide a water purifier that does not require time to maintain the use of the water purifier.
