Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a water purifier for producing drinking water suitable for drinking by treating raw water unsuitable for drinking.

[0002]

2. Description of the Related Art Conventionally, various water purifiers have been proposed for securing drinking water when the supply of water supply is cut off due to a disaster or the like. In particular, in recent years, as consumers' awareness of disasters has increased, small-sized water purifiers for emergency use have been marketed.

[0003] These water purifiers purify raw water that is unsuitable for drinking to produce drinking water. For example, some water purifiers recover distilled water by evaporating the raw water to obtain drinking water.

[0004] However, a heat source is required to quickly obtain distilled water, and it is difficult to use distilled water in an emergency such as a disaster. Therefore, a simpler water purifier that obtains drinking water by filtering raw water is commercially available. Since such a water purifier has a simple structure, it can be reduced in size and cost, and has been relatively widely used.

[0005]

However, in the above-mentioned conventional water purifier, for example, raw water is introduced from above the filter medium,
It was waiting for the raw water to permeate the filter media by gravity. In other words, there is a problem that it is necessary to wait for the raw water to be naturally filtered, which takes a very long time.

[0006] Particularly in an emergency, it is unavoidable that drinking water must be produced using water from lakes, marshes and rivers as raw water. For this reason, emergency water purifiers
Many have a very fine filter medium so that fine foreign substances and various germs can be removed. Therefore, the time required for filtering the raw water is further increased, and it has been difficult to promptly secure a large amount of drinking water.

Furthermore, water purifiers manufactured for emergency use must be miniaturized in order to ensure convenience when stored during normal times, that is, when not in use. Therefore, there is a problem that it is difficult to improve the production capacity of drinking water.

On the other hand, in an emergency, clean water is required for various uses such as medical use in addition to drinking. For this reason,
A water purifier that can quickly produce clean drinking water has been desired.

Therefore, an object of the present invention is to make it possible to easily store a water purifier used in an emergency when not in use and to improve the production capacity of drinking water.

[0010]

In order to achieve the above object, according to the first aspect of the present invention, there is provided a main body having an intake port to which raw water is supplied, and purifying water at the time of passing water. A water-passage treatment section containing a water-passage treatment material in a case; and a pressure feed section that applies pressure to raw water supplied from an intake port of the main body to pass through the inside of the water-passage treatment section. The water treatment section and the pumping section are each detachably provided to the main body.

Here, the raw water is water from which drinking water is obtained by the water purifier according to the present invention, and its purity is not particularly limited. Examples of the water-permeable material included in the water-permeable processing unit include, for example, a filter that purifies water by removing foreign substances in water by filtration, or a substance that adsorbs foreign substances in water and compounds and ions dissolved in water. An adsorbent to be removed, a catalyst that decomposes foreign substances and compounds in water using a catalytic action, and the like can be given. Specific examples of the filter include paper, non-woven cloth, non-woven cloth, hollow fiber membrane, sponge, sponge, and the like using natural fibers and synthetic resin fibers. In addition, as the adsorbent, activated carbon or granular sulfite,
Ion exchange resins and the like. In addition, as the water-passing treatment material, a material that purifies water by coagulating foreign substances in raw water with a coagulant and then filtering, and other known materials used for water purification can be used. is there. The pumping section transfers the raw water by applying a negative pressure to the raw water and sucks the raw water, or pressurizes and feeds the raw water by applying a positive pressure, such as a pump driven by human power or electricity or an internal combustion engine. Is mentioned.

According to the first aspect of the present invention, there is provided a main body having an intake port to which raw water is supplied, and a water passage treatment section containing a water passage treatment material for purifying water at the time of passage of water in a case. , A pressure feed unit for applying pressure to raw water supplied from an intake port of the main body and passing the raw water through the water flow processing unit, and the water flow processing unit and the pressure feed unit are configured to be detachable from the main body. In some cases, the water treatment section and the pumping section can be detached from the main body and stored. Thus, storage during normal times, that is, when not in use, is convenient. Further, the water purifier according to the present invention applies pressure to the raw water to force the water to pass through the water passage treatment section, so that a large amount of raw water can be quickly purified.
Therefore, it is possible to provide a water purifier that is convenient for storage and has high production capacity for drinking water.

[0013] In the water purifier according to the first aspect of the present invention, as in the second aspect of the invention, the main body has at least one pedestal that can be attached to any of the water passage processing section and the pressure feeding section. It is good also as composition characterized by having two or more.

In this case, the main body is provided with at least one pedestal that can be attached to either the water passage processing section or the pressure feeding section. Therefore, another water passage processing section is attached to this pedestal. If it does, it becomes a purification device having only a plurality of water passage processing units in addition to the water passage treatment unit arranged in advance in the main body, and if the pumping unit is mounted on the pedestal, it will have a pumping unit and a water passage processing unit It becomes a purification device.

[0015] Recently, many water purifiers are commercially available which are used for the purpose of obtaining a more delicious drinking water by removing the smell of smell and the like from ordinary tap water. Since these water purifiers are connected to a water pipe to perform filtration by the pressure of the water supply, a member corresponding to a pressure feeding unit such as the water purifier according to the present invention is unnecessary. Therefore, if the pumping unit is removed from the water purifier according to the present invention and connected to a water supply water pipe as a configuration having only a water passage treatment unit, it can be used as a water purifier for purifying tap water. Also, in an emergency, if a pumping unit is attached to the main body instead of the single water passage processing unit, it can be used as a water purifier that can obtain drinking water from unsuitable drinking water other than tap water. This makes it possible to provide a highly convenient water purifier that can be effectively used even during normal times. Also, it is only necessary to store only the pumping section and the spare water passage processing section etc. in case of emergency,
The labor for storage can be saved.

Alternatively, in the water purifier according to claim 1,
As in the invention according to claim 3, the pressure feeding section has a predetermined exterior, the main body includes a plurality of pedestals having the same shape, and a case that the water passage processing section has A configuration may be adopted in which a fitting portion that fits into a pedestal of the main body is provided on an exterior of the pressure feeding unit.

In this case, the main body is provided with a plurality of pedestals, and a fitting portion that fits into the pedestal of the main body is provided on the case of the water-passage processing section and on the exterior of the pumping section. The pedestal can be attached to any of the water passage processing section and the pressure feeding section. With this configuration, if only a plurality of water passage treatment sections are mounted on the main body, and tap water is supplied to the intake port of the main body, it can be used as a water purifier for purifying tap water. Further, if the main body is provided with a water treatment section and a pressure feeding section, it can be used as a water purifier for obtaining drinking water from raw water other than water supply in an emergency. Further, only the pumping section and the spare water passage processing section need to be stored for an emergency, so that the time and effort for storage can be saved.

Further, in a plurality of pedestals of the same shape, the position where the pumping unit and the water passage processing unit are mounted and the number of the pumping unit and the water passage processing unit to be mounted are arbitrary. For this reason, it is also possible to change the positional relationship between the pumping unit and the water passage processing unit and the number of units to be mounted according to the situation. Thus, it is possible to more reliably obtain clean drinking water by using a large number of water passage processing units, and it is also possible to reduce the number of water passage processing units to be used and to save money. Therefore, it is possible to provide a water purifier that can be effectively used even during normal times, is highly convenient, and can be used in various ways depending on the situation.

In the water purifier according to any one of the first to third aspects, as in the invention according to the fourth aspect, an intake pipe extending to the outside of the main body is provided at an intake port of the main body. A filter for filtering raw water flowing into the water intake pipe may be provided at a tip of the water pipe.

In this case, since an intake pipe having a filter at the tip is provided at the intake port of the main body, the operation of obtaining drinking water can be started quickly by immersing the intake pipe in raw water. Therefore, the water purifier according to the present invention can be easily moved to a place where raw water is stored and used. Furthermore, since the raw water is filtered by the filter arranged at the tip of the water intake pipe, foreign substances and dirt flowing into the water purifier are reduced, and excessive contamination and clogging of the water flow treatment section and the pumping section are prevented. It is possible to extend the service life of the water purifier and prevent breakdown.

Further, in the water purifier according to any one of the first to fourth aspects, as in the invention according to the fifth aspect, the pressure-feeding section includes a suction port communicating with a water intake port of the main body, and suction from the suction port. A water storage unit having a discharge port for discharging the collected water, and applying a negative pressure to the water storage unit according to a user's manual operation to suck water from the suction port into the water storage unit, And a pressurizing means for applying a positive pressure to the water storage unit in response to a manual operation by a user and discharging the water in the water storage unit from the discharge port.

In this case, the pumping section sucks water from the suction port according to a user's manual operation, and discharges water from the discharge port according to the user's manual operation. That is, since the pumping section functions as a manual pump, a large amount of raw water can be passed to the water treatment section without using a power source such as electric power or an internal combustion engine. Therefore, a large amount of drinking water can be obtained quickly without using a special power source.

The suction port of the pumping section may be in direct communication with the intake port of the main body, or may be configured to be in communication with the intake port through a water flow treatment section. Therefore, in the main body, the arrangement relationship among the water intake, the pumping unit, and the water treatment unit is not particularly limited.

Further, in the water purifier according to claim 5,
According to a sixth aspect of the present invention, the pressure feeding section may further include a stop valve for stopping movement of water in the direction from the inside of the water storage section to the outside of the suction port. .

In this case, the water in the water storage section of the pumping section is restricted by the stop valve so that the water moves in only one direction, so that the backflow of water during the operation of the pumping section can be prevented. For this reason, the pumping section can be operated efficiently, and drinking water can be obtained quickly. Further, with the improvement of the efficiency of the pumping unit, a larger pressure can be applied, so that, for example, a height difference between the water purifier and the surface of the raw water is large, or the resistance of the raw water when passing therethrough is large. Even when the processing material is used, drinking water can be obtained quickly.

Furthermore, if the stop valve according to the present invention is configured to always keep the closed state in a state where the pumping section is not operated and the water purifier is not used, sanitary reliability can be improved. Generally, when a water purifier is left standing with water stored therein, various bacteria may propagate in the water purifier. For this reason, if you stop using the water purifier, due to hygiene considerations,
In some cases, water was passed for a certain period of time to replace all the water that had accumulated inside the water purifier. However, if the stop valve is configured to always keep the closed state when the water purifier is not used, movement and spread of various bacteria inside the water purifier in a stationary state can be suppressed, and propagation of various bacteria can be suppressed. Surface reliability can be improved.

The raw water taken from the water intake pipe 6 is pumped by the pump cartridge 3, filtered and purified by the cartridges 4 and 5, and then discharged from the purified water discharge pipe 8.

Hereinafter, each part of the water purifier 1 will be described in detail. The gantry 2 is composed of a base part 21 located on the lower side in the figure and a main body 22, and has an intake pipe connecting part 261 and a discharge pipe connecting part 266. Pipes 262, 263, between the intake pipe connecting part 261 and the discharge pipe connecting part 266
264, 265, and the receiving portion 23 is disposed between the pipe 262 and the pipe 263.
The receiving part 24 is arranged between the pipe 264 and the pipe 264, and the receiving part 25 is arranged between the pipe 264 and the pipe 265. Therefore, pipes 262, 263, 264, 2
A water flow path from the intake pipe connection part 261 to the discharge pipe connection part 266 is formed by the receiving part 65, the receiving parts 23, 24, and 25.

The water intake pipe 6 is connected to the water intake pipe connection part 261, and a sponge filter 7 is attached to the tip of the water intake pipe 6. The sponge filter 7 is a sponge or sponge made of synthetic resin, and filters raw water sucked into the water purifier 1 from the water intake pipe 6, and filters out a few mm (millimeter) or a few millimeters of foreign substances contained in the raw water. Foreign matter of the above size is removed. The intake pipe 6 is made of synthetic or natural rubber,
The pipe is made of synthetic resin or metal, and its length is arbitrary. The bellows-like purified water discharge pipe 8 is connected to the discharge pipe connection part 266.

Next, the structure of the pump cartridge 3 will be described with reference to FIG. Pump cartridge 3
Is configured by housing each part in a substantially cylindrical case 31. The upper end of the case 31 is narrowed down narrowly, and a hole 311 communicating with the inside of the case 31 is formed in the end surface thereof. The upper end of the case 31 is protected by an upper cover 312 in which a hole having the same diameter as the hole 311 is formed.

The pump cartridge 3 has a hole 3
A shaft 32 extending through the inside and outside of the case 31
Are arranged along the axial center of the case 31. The shaft 32 is a rod-like member extending in the vertical direction, and the upper end is formed wide to form a handle 321. The handle 321 is a part that a user operating the pump cartridge 3 grips with his / her hand, and may be shaped to fit the user's hand.

Further, the shaft 32 is supported by a support plate 323 above the pressurizing plate 322. The support plate 323 is fixed to the inner surface of the case 31, and a hole through which the shaft 32 passes is formed at the center. The shaft 32 is
It is not fixed to the case 31 and the support plate 323 and can move up and down. The shaft 32 and the support plate 3
The pressurizing means of the water purifier 1 is constituted by 23.

The lower end of the shaft 32 is joined to the pressurizing plate 322 below the case 31. The pressurizing plate 322 is a disc-shaped member that is in close contact with the inner surface of the case 31, and is movable up and down so as to rub against the inner surface of the case 31. Therefore, the shaft 32 and the pressurizing plate 322 move up and down inside the case 31 as a unit.

A space is formed below the pressurizing plate 322 in the case 31. This space serves as a water storage section 324, and the volume of the water storage section 324 changes with the movement of the pressurizing plate 322. In addition, a discharge pipe 34 is provided below the water storage section 324. The discharge pipe 34 is a hollow pipe located at the center of the shaft of the case 31, protrudes downward from the case 31, and communicates with the pipe 263.

A non-woven cloth filter 33 is disposed around the discharge pipe 34. The non-cotton cloth filter 33 is a filter made of synthetic resin, natural fiber, or the like, and has a gap of about 0.5 mm (millimeter), for example. A stop valve 35 is provided below the non-woven cloth filter 33, and an opening of the pipe 262 is located below the stop valve 35. Therefore, pipe 262
Is fed into the pump cartridge 3 through the stop valve 35 and the non-woven cloth filter 33,
The non-cotton cloth filter 33 constitutes an inlet.

When the pressurizing plate 322 rises, the water storage section 32
Raw water flows into pipe 4 from pipe 262. At this time,
Since the raw water passes through the stop valve 35 and the non-woven cloth filter 33, foreign matters having a predetermined size or more, for example, 0.5 mm or more, are removed by the non-woven cloth filter 33. Also,
When the pressurizing plate 322 descends, the raw water in the water storage section 324 is discharged from the discharge pipe 34 to the pipe 263.

Here, the lower structure of the case 31 including the discharge pipe 34 will be described with reference to FIG. FIG. 3 is a plan view showing a configuration of a joint portion between the pump cartridge 3 and the gantry 2. FIG.
(B) shows the configuration of the lower surface of the pump cartridge 3. In FIG. 9A, reference numerals 231 and 232 denote recesses, 233 denotes a socket, 234 denotes an inlet, 235 denotes an outlet, and 236 denotes a claw fitting portion. In FIG. 3B, reference numeral 313 denotes a claw.

As shown in FIG. 3A, the receiving portion 23 has a concave portion 231 and a concave portion 232 provided concentrically. The diameter of the concave portion 231 on the outer peripheral side is substantially equal to the outer diameter of the case 31, the concave portion 232 on the inner peripheral side is formed one step lower than the concave portion 231, and a socket 233 stands upright at the center. The socket 233 has a hollow cylindrical shape, and its inner diameter is substantially equal to the outer diameter of the discharge pipe 34.

Outside the socket 233, an inlet 234 is opened at the bottom of the recess 232. The inlet 234 is an opening communicating with the pipe 262 (see FIG. 1), and raw water is introduced into the pump cartridge 3 from the inlet 234. Further, inside the socket 233, a discharge port 235 is opened on the bottom surface of the concave portion 232. The discharge port 235 is an opening communicating with the end of the pipe 263, and is an opening through which water is discharged from the pump cartridge 3.

On the other hand, as shown in FIG. 3B, a central discharge pipe 34 and a stop valve 35 disposed around the discharge pipe 34 are exposed on the lower surface of the pump cartridge 3.

Therefore, the pump cartridge 3 is
3, the case 31 fits into the recess 231,
The discharge pipe 34 is fitted inside the socket 233 and the stop valve 3
5 is located directly above the concave portion 232. And socket 2
The space between the pump cartridge 3 and the receiving portion 23 is kept watertight because the space between the pump cartridge 3 and the receiving portion 23 is tightly joined between the 33 and the discharge pipe 34 and between the outer periphery of the concave portion 231 and the case 31.
At the joint between the pump cartridge 3 and the receiving part 23, it is possible to further improve the watertightness by appropriately arranging silicone rubber, resin or rubber packing. As described above, each part of the bottom surface of the pump cartridge 3 shown in FIG. 3B constitutes a fitting part in the water purifier 1.

As shown in FIG. 3B, on the outer periphery of the case 31, two flat tabs 313 and 313 opposed to each other with the case 31 interposed therebetween are provided. FIG. 3 (a)
As shown in the figure, outside the concave portion 231 on the upper surface of the main body 22,
Two claw fitting portions 23 opposed to each other with the concave portion 231 interposed therebetween
6,236 are provided. Claw fittings 236, 23
Reference numeral 6 denotes a hole into which the claws 313 and 313 are inserted. The number of the claws 313, 313 and the claws 236, 236 is not limited as long as the number of the claws 313, 313 and the claws 236, 236 are the same.

When the pump cartridge 3 is joined to the receiving portion 23, the pawls 313 and 313 of the case 31 are inserted into the pawl fitting portions 236 and 236, and the case 31 is rotated. Fitting part 23
6 and 236, and the pump cartridge 3 is fixed to the main body 22. In this state, the pump cartridge 3 does not fall out of the main body 22 due to an increase in internal pressure or an external force. When removing the pump cartridge 3 from the receiving portion 23, the pump cartridge 3 may be rotated in a direction in which the claws 313, 313 are disengaged from the claw fitting portions 236, 236, and the pump cartridge 3 may be pulled out.

FIG. 4 is a view showing the structure of the stop valve 35, FIG. 4 (a) is a plan view, and FIG. 4 (b) is a sectional view. As shown in FIGS. 4A and 4B, the stop valve 35 is configured by disposing a plurality of flaps 352 in a base 351 shape.

At the center of the base 351, a shaft hole 353 substantially equal to the outer diameter of the discharge pipe 34 is provided, and around the shaft hole 353, a plurality of flaps 352 are provided. Holes (not shown) penetrating the base 351 are formed in portions covered by the flaps 352, respectively. The flap 352 is a flat member, and one end of the flap 352 is
51, and can be turned up and down on one surface side of the base 351 about the one end as shown by an arrow in FIG. 4B.

That is, when the upward force is applied to the stop valve 35 from below the stop valve 35, the flap 352 rotates upward, and the hole closed by the flap 352 is opened. On the other hand, when a downward force is applied, the flap 352 does not move in close contact with the base 351. For this reason, the stop valve 35 functions as a valve that allows the water flowing from the bottom to the top to pass through and restricts the flow of the water from the top to the bottom.

The stop valve 35 may be configured so that the flap 352 is always closed when the pump cartridge 3 is not operated, that is, when the pump cartridge 3 is left still. In this case, while the water purifier 1 is in the stationary state, movement of water and various bacteria between the pump cartridge 3 and the cartridge 4 can be suppressed, and propagation of various bacteria inside the water purifier 1 can be suppressed. In particular, the water purifier 1 shown in FIG. 1 is for taking raw water that is not suitable for drinking from the water pipe 6, and by suppressing the propagation of various bacteria, the sanitary reliability of the water purifier 1 can be increased.

Next, the operation of the pump cartridge 3 will be described with reference to FIG. When the handle 321 is pulled upward by a user's manual operation in a state where the pump cartridge 3 is joined to the receiving portion 23, the pressurizing plate 322 moves up together with the shaft 32, and the internal volume of the water storing portion 324 increases. , A negative pressure is applied to the inlet 234 (see FIG. 3A).

The raw water is sucked up from the pipe 262 by the negative pressure applied to the inlet 234. This raw water is a stop valve 3
5 through a non-woven cloth filter 33,
It is introduced into the water storage unit 324.

On the other hand, the handle 321 is operated by the user.
Is pressed down, the pressurizing plate 32 together with the shaft 32 is pressed.
2 drops. Then, the internal pressure of the water storage unit 324 rises, and a positive pressure is applied to the water in the water storage unit 324, and the water storage unit 3
The water in 24 is sent from discharge pipe 34 to pipe 263.

When a positive pressure is applied to the water in the water storage section 324, the flap 352 of the stop valve 35 is
1, the water in the water storage section 324 does not flow backward to the pipe 262 side. Further, since the cartridge 4 described later has the stop valve 35, when the pressure in the water storage section 324 decreases, water is discharged from the discharge pipe 34 through the water storage section 3.
It is not sucked into 24.

As described above, in the pump cartridge 3, when the handle 321 is moved up and down by a user's manual operation, raw water is sucked up from the pipe 262 and sent to the pipe 263 under pressure. In the pump cartridge 3, the width of the handle 321 moving up and down can be set to an arbitrary width by adjusting the height inside the case 31 and the position of the support plate 323.

Next, the configuration of the cartridge 4 will be described with reference to FIG. As shown in FIG. 5, the case 41 has a cylindrical shape and has an upper portion opened like the case 31 (see FIG. 2), but the opening is covered by an upper cover 411. Therefore, the inside of the case 41 is kept watertight. Although the opening may be omitted, the same member as the case 31 can be used as the case 41 with the configuration shown in FIG.

In the case 41, a pre-filter 42 is provided at a lower portion as a water-permeable material, and a hollow fiber membrane filter 43 is provided at an upper portion. Pre-filter 42
The support plate 46 is fixed to the lower end of the hollow fiber membrane filter 43, and the support plate 47 is fixed to the upper end of the filter 43. The support plate 46 and the support plate 47 support the filter.

A shaft pipe 44 is provided upright at the center of the shaft of the case 41. The shaft pipe 44 is a hollow rod-shaped member extending from the upper portion of the case 41 to the lowermost end. An upper support 45 is provided at the upper end of the shaft pipe 44.
The upper support 45 supports the upper part of the shaft pipe 44, collects water overflowing on the upper surface of the support plate 47, and guides the water into the shaft pipe 44 as described later.

The pre-filter 42 is a filter made of diatomaceous earth and a synthetic cloth of polypropylene, for example, about 0.45 μm (micrometer).
It has a small gap. Therefore, when water passes through the pre-filter 42, foreign matter having a size of about 0.45 μm or more is removed.

The hollow fiber membrane filter 43 is, for example, 0.1
This is a filter using a hollow fiber membrane having a hole having a diameter of about μm to 0.01 μm. Therefore, foreign matter having a size of, for example, 0.01 μm or more, that is, foreign matter such as germs can be removed by filtration using the hollow fiber membrane filter 43.

The prefilter 42 and the hollow fiber membrane filter 43 are formed so as to have a cylindrical outer diameter, and have a through hole through which a shaft pipe 44 passes at the center of the shaft. The through hole is larger than the outer diameter of the shaft pipe 44, and the inner surface of the through hole and the shaft pipe 44 are separated from each other by a predetermined distance. The outer diameter of the pre-filter 42 and the hollow fiber membrane filter 43 is smaller than the inner diameter of the case 41. Therefore, the pre-filter 42 and the hollow fiber membrane filter 43
Is separated from the inner surface of the case 41 by a predetermined distance.

A stop valve 35a is provided between the prefilter 42 and the hollow fiber membrane filter 43. The stop valve 35a has the same configuration as the stop valve 35 shown in FIG.
And a support plate 4 located on the lower surface of the hollow fiber membrane filter 43.
6 is arranged so as to block the gap. This stop valve 35
Due to a, movement of water from the hollow fiber membrane filter 43 to the pre-filter 42 is restricted.

Further, below the support plate 46 supporting the pre-filter 42, a stop valve 35b is disposed so as to close the lower surface of the case 41. The configuration of the stop valve 35b is as follows.
This is the same as the stop valve 35 of the pump cartridge 3. The stop valves 35a and 35b have a shaft hole corresponding to the shaft hole 353 (FIG. 4A) of the stop valve 35. The diameter of the shaft hole is substantially equal to the outer diameter of the shaft pipe 44. Shall be equal.

The structure of the lower surface of the cartridge 4 is the same as the structure of the lower surface of the pump cartridge 3 shown in FIG. 3B, and the receiving portion 24 has the same structure as the receiving portion 23.
Therefore, the joint between the cartridge 4 and the receiving portion 24 is the same as the structure shown in FIGS. 3A and 3B.

FIG. 6 shows the structure of the support plates 46 and 47.
FIG. 7A is a plan view showing the configuration of the support plate 46.
FIG. 4B is a plan view illustrating a configuration of the support plate 47. FIG.
As shown in (a), the support plate 46 is a disk having a diameter substantially equal to the inner diameter of the case 41, and has a shaft pipe 44 in the center.
A shaft hole 461 through which (FIG. 5) passes is provided. Shaft hole 46
The diameter of 1 is substantially equal to the outer diameter of the shaft pipe 44. Support plate 46
Is made of a water-impermeable material such as a synthetic resin or a metal. A plurality of water holes 462 are formed in the support plate 46 along the outer circumference.

As shown in FIG. 6B, the support plate 47
Like the support plate 46, it is a disk made of a water-impermeable material, and its outer diameter is substantially equal to the inner diameter of the case 41. Also,
In the center of the support plate 47, a shaft hole 471 having a diameter substantially equal to the outer diameter of the shaft pipe 44 is provided.
A plurality of water passage holes 472 are formed along the circumference of.

As shown in FIG. 5, a stop valve 35b is provided at the lower end of the case 41 so that the pump cartridge 3
Raw water pumped through the pipe 263 from the
5b flows below the support plate 46. This raw water flows into the outside of the prefilter 42 through the water holes 462 of the support plate 46, and permeates the prefilter 42 while moving upward. Since the support plate 47 has no water flow path other than the shaft hole 471, the raw water does not move above the support plate 47 but permeates into the pre-filter 42 under a pressure.

The water that has permeated from the outside of the pre-filter 42 reaches the space between the inside of the pre-filter 42 and the shaft pipe 44, rises in this space, and reaches the support plate 47. Since the support plate 47 is provided with the water holes 472 on the shaft pipe 44 side, the water that has passed through the pre-filter 42 rises further through the water holes 472, passes through the stop valve 35a, and becomes hollow. It reaches the support plate 46 located at the lower end of the thread membrane filter 43.

The water that has passed through the pre-filter 42 passes through the water holes 462 of the support plate 46 and rises between the outside of the hollow fiber membrane filter 43 and the case 41 while penetrating the hollow fiber membrane filter 43. The water that has permeated the hollow fiber membrane filter 43 leaches into the space between the inside of the hollow fiber membrane filter 43 and the shaft pipe 44 and rises in the space. The water that has passed through the hollow fiber membrane filter 43 overflows through the water holes 472 of the support plate 47 to the upper portion, flows into the shaft pipe 44 via the upper support 45, passes through the shaft pipe 44, and flows through the pipe 264. Sent to

Therefore, in the cartridge 4, the water pumped from the pump cartridge 3 is filtered by the pre-filter 42 and the hollow fiber membrane filter 43 and sent out to the pipe 264. In this process, foreign matters floating in the water are removed up to various bacteria and the like. Further, the pre-filter 42 and the hollow fiber membrane filter 43 are very fine and have a high resistance when water passes therethrough. However, since the water flowing into the cartridge 4 is pumped by the pump cartridge 3, it quickly Filtered.

Further, the cartridge 4 has a stop valve 35 a between the pre-filter 42 and the hollow fiber membrane filter 43.
Is disposed, and the stop valve 35b is disposed below the pre-filter 42, so that the water in the cartridge 4 does not flow backward toward the pump cartridge 3.

Here, the stop valves 35a and 35b may be configured to be always closed while the water purifier 1 is in the stationary state, similarly to the stop valve 35. In this case, since the pre-filter 42 and the hollow fiber membrane filter 43 are separated by the stop valve 35a in a state where the water in the cartridge 4 does not flow, the pre-filter 42 and the hollow fiber membrane filter 4 are separated.
3 can be prevented from moving and spreading. Further, since the pre-filter 42 and the pump cartridge 3 are separated by the stop valve 35b, movement and diffusion of various bacteria from the pump cartridge 3 to the cartridge 4 can be suppressed. Thereby, propagation of various germs in the cartridge 4 can be suppressed, and the sanitary reliability of the water purifier 1 can be further improved. It should be noted that the above-described effect can be obtained even if only the stop valve 35a is provided in the cartridge 4.

Next, the configuration of the cartridge 5 will be described with reference to FIG. The case 51 is configured similarly to the case 41 (see FIG. 5). That is, the case 51 is a cylindrical member and has an upper opening, and this opening is covered by the upper cover 511. For this reason,
The inside of the case 51 is kept watertight while being connected to the receiving portion 25. The opening may be omitted, but if the configuration shown in FIG.
Available as 1.

Similarly to the case 41, a shaft pipe 44 is provided at the center of the shaft of the case 51, and an upper support 45 is provided at the upper end of the shaft pipe 44.

Therefore, inside the cartridge 5, the water sent from the cartridge 4 via the pipe 264 flows in from below the case 51, moves upward and reaches the upper support 45, and from the upper support 45. It passes through the inside of the shaft pipe 44 and is discharged to the pipe 265.

Further, the cartridge 5 incorporates coconut shell activated carbon 54 and calcium sulfite 55 which is a kind of sulfite as a water-permeable material. Calcium sulfite 55
Are formed, for example, in a granular form. These coconut shell activated carbon 54 and calcium sulfite 55 make it possible to
By absorbing and removing impurities floating or dissolved in water, such as inorganic ions and organic / inorganic molecules, water turbidity and odor can be removed.

In the cartridge 5, a total of nine partition plates 52, 53 are provided which divide the space between the partition plate 57 disposed below the case 51 and the upper support plate 58 at substantially equal intervals in the axial direction. ing. With this structure, a plurality of four-layer compartments densely storing the coconut shell activated carbon 54 as the water-permeating material and six-layer compartments densely containing calcium sulfite 55 as the water-permeating material are formed in the axial direction of the cartridge 5. It has a multilayer structure.

FIG. 8 is a plan view showing the partition plate 52 (53). As shown in the figure, the partition plate 52 (53) is a disk having an outer diameter substantially equal to the inner diameter of the cartridge 5, and has a shaft hole 521 having an inner diameter equal to the outer diameter of the shaft pipe 44 at the center thereof, A water hole 522 for passing water is provided at a nearby eccentric position. As shown in FIG. 8, the shaft pipe 5 fits tightly into the shaft hole 521 of the partition plate 52 (53), while the outer edge of the partition plate 52 (53) is
By being fitted to the inner wall without any gap, it is divided into two adjacent sections that are communicated only by the water holes 522. When such partition plates 52 (53) are arranged at predetermined intervals in the cartridge 5 to form a total of 10 layers, the partition plate 52 and the partition plate 53 are positioned such that the position of the water passage hole 522 is in the cartridge. The direction of the other partition plate 53 relative to the one partition plate 52 is substantially 18 so as to be staggered with respect to the axis 5 (shown alternately in the left and right directions in the cross-sectional view of FIG. 7).
Adjust to a position rotated 0 degrees.

FIG. 9 is a plan view showing the structure of the partition plate 57. As shown in the figure, the partition plate 57 has a shaft hole 571 through which the shaft pipe 44 passes, and a plurality of water holes 572 are arranged around the shaft hole 571. FIG. 10 is a plan view showing the configuration of the upper support plate 58. As shown in FIG. 10, the upper support plate 58 has a shaft hole 581 through which the shaft pipe 44 passes.
A plurality of water holes 583 arranged around the shaft hole 581;
And, it has a water passage hole 582 arranged on the outer peripheral side of the water passage hole 583. Water hole 572, water hole 582 and water hole 5
83 is for passing water across the partition plate 57 and the upper support plate 58.

Further, as shown in FIG. 7, a stop valve 35c is provided between the uppermost section containing the calcium sulfite 55 and the upper support plate 58. Stop valve 35c
Has a configuration similar to that of the stop valve 35 shown in FIG. 4, but has a hole in the center thereof into which the upper support 45 can be inserted. By providing the stop valve 35c, backflow of water from above the upper support plate 58 into the compartment where the calcium sulfite 55 is stored can be prevented.

Here, the stop valve 35c is connected to the stop valve 35.
Similarly to the above, while the water purifier 1 is in the stationary state, the water purifier 1 may always be in the closed state. In this case, in a state where the water in the cartridge 5 does not flow, the section containing the coconut shell activated carbon 54 and the calcium sulfite 55 and the pipe 265 are separated by the stop valve 35c. Thereby, movement and diffusion of various bacteria and the like from the cartridge 5 to the pipe 265 can be suppressed, so that the reliability of sanitary water discharged from the purified water discharge pipe 8 through the pipe 265 can be further improved.

In the cartridge 5 having the above structure,
The water rises through the non-woven cloth filter 56 and the partition plate 57 through the stop valve 35. Thus, the water holes 5 penetrating through the partition plate 52 for partitioning the first-layer section and the second-layer section.
Since the water flow 22 is provided at an eccentric position near the outer edge, the water flow intersects in the axial direction of the cartridge 5 (in FIG. 7,
A water flow flowing from right to left as indicated by the arrow) is generated and passes through the layer of coconut shell activated carbon 54. Water flows from the first layer section through the water holes 522 into the second layer section, but penetrates the partition plate 53 that separates the second layer section and the third layer section. Since the water passage hole 532 is located substantially symmetrically with respect to the axis of the cartridge 5 with respect to the water passage hole 522 of the partition plate 52 through which water has previously passed, the orientation of the partition plate 52 and the shaft hole 521 is changed this time. Generates a water flow in the opposite direction to the water flow in the compartment (a water flow flowing from left to right as indicated by an arrow in FIG. 7). In this way, water is sequentially passed through these compartments so that water flows intersecting in the axial direction of the cartridge 5 are alternated through these ten layers of compartments.

Most of the general water-passage treatment cartridges allow water to pass straight through the water-passage treatment material having a laminated structure along the axial direction of the cartridge. Therefore, in order to increase the distance that water passes through the water passage treatment material, the length of the cartridge needs to be increased.
On the other hand, according to the cartridge 5 having the above configuration,
The direction of the water flow is changed to the direction that intersects the axial direction of the cartridge in each compartment, and the direction of the water flow is passed from bottom to top so as to alternate between multiple compartments, so that water is stored in each compartment. It is possible to lengthen the distance that passes through the provided water-permeable treatment material. Therefore, the processing capacity of the cartridge 5 whose main purpose is to remove substances having negative ion characteristics such as residual chlorine can be further increased as compared with a cartridge of the same size as the conventional one, while securing a necessary amount of treated water. . Since the cartridge 5 contains the coconut shell activated carbon 54 and the sulfite (calcium sulfite 55) as a water-passing treatment material, it is also necessary to remove odor and turbidity in addition to the anionic substances such as residual chlorine. Can be.

As described above, according to the water purifier 1 according to the embodiment of the present invention, when the user moves the handle 321 of the pump cartridge 3 up and down, the raw water is transferred from the intake pipe 6 to the pump cartridge. 3, and further fed to the cartridge 4 by pressure. In the cartridge 4, raw water is filtered by the pre-filter 42 and the hollow fiber membrane filter 43, and the cartridge 5
Sent to Then, in the cartridge 5, the coconut shell activated carbon 54 and the calcium sulfite 55 cause
The water is further purified, and the purified water is discharged from the purified water discharge pipe 8.

Therefore, drinking water can be obtained by manual operation of the user without preparing a special power source. In addition, since the raw water is pumped through the water purifier 1 by operating the pump cartridge 3, a large amount of drinking water can be obtained quickly. In particular, the pump cartridge 3 is provided with a stop valve 35, and the cartridge 4 is provided with a stop valve 35a,
35b, and the cartridge 5 has a stop valve 3
5c are arranged. Therefore, the pump cartridge 3
The water does not flow backward in the water purifier 1 with the operation of
While the water purifier 1 can be operated stably, the movement and diffusion of various bacteria and dirt can be suppressed, and the reliability in hygiene can be improved.

Further, receiving portions 23 and 2 of water purifier 1
The pump cartridges 4 and 25 have the same shape, and can be mounted on any of the pump cartridge 3, the cartridge 4 and the cartridge 5. Therefore, the mounting positions of the pump cartridge 3, the cartridge 4, and the cartridge 5 are arbitrary.

The intake pipe connecting portion 261 of the gantry 2
Is connected to an intake pipe 6 to which a sponge filter 7 is attached at the tip. For this reason, by filtering the raw water flowing into the gantry 2 through the water intake pipe 6 with the sponge filter 7, a relatively large foreign substance can be removed, and the water purifier 1 can be prevented from being soiled or broken down due to the foreign substance.

Here, another usage example of the water purifier 1 will be described.
This will be described with reference to FIG. FIG. 11 is a diagram showing another example of use of the water purifier 1 according to the present invention. In the figure, the same reference numerals are given to the parts having the same configuration as the water purifier 1 shown in FIG. 1, and the description is omitted.

In FIG. 11, reference numeral 10 denotes a case cover,
Reference numerals 1 and 12 denote cartridges. In the cartridge 11, 111, 112 and 113 are granular ceramics, 11
Reference numeral 4 denotes a partition plate, reference numeral 115 denotes a non-cotton cloth filter, and in the cartridge 12, reference numeral 121 denotes quartz diorenite (Ioishi); 122, a convex lens;
25 is an upper support, and 126 is a non-cotton filter.

In the water purifier 1 shown in FIG.
Cartridges 5 in receiving portions 23, 24, 25 of
The cartridge 11 and the cartridge 12 are joined. Although not shown, a water supply pipe is connected to the water intake pipe connection part 261, and tap water is supplied to the water intake pipe connection part 261 at a predetermined water pressure.

The cartridge 11 is made of three kinds of ceramics (crystalline aluminosilicate-based porous fired granulated filter medium) having different grain sizes as a water-permeable material in a case similar to the case 51 of the cartridge 5. It contains granular ceramics 111, 112, 113.

Specifically, the cartridge 11 is vertically divided into three layers by a plurality of partition plates 114 and a non-woven cloth filter 115. The section located in the upper layer is filled with the granular ceramic 111 in the entire section. The granular ceramic 111 is an extremely granular ceramic having very small grains. On the other hand, a predetermined amount of the granular ceramic 112 having an average particle size of 2 mm to 3 mm is accommodated in a section located in the lower layer.
A large-sized granular ceramic 113 having an average particle size of 5 mm to 6 mm is accommodated.

In this case, the granular ceramics 112, 113
Is adjusted so as to secure a space above the lower two sections in which the granular ceramics 112 and 113 can freely move in the sections. The preferred capacity of the ball-shaped ceramic is such that the ball-shaped ceramic occupies about half of the compartment as shown.

Water is introduced into the water introduction port of the cartridge 11 having the above-described structure, and water is sequentially passed from the lower layer to the upper layer across the above-described sections. Then, first, in the lower section,
The large-sized granular ceramics 113 which have been deposited downward by gravity are sowed into the space formed at the upper part in the compartment by the water flow and water pressure going upward from the bottom, thereby causing friction between the granular ceramics 113. And / or cause a collision. The ceramic is a substance that cannot be removed by the cartridge 5, for example, a physicochemical action such as adsorption removal of suspended matter contained in water and an adsorption decomposition of a water-soluble substance (for example, ammonia) and a biochemical purification action. The effect is synergistic, and this ion effect can be amplified when friction and collision between ceramics are generated without interruption. Next, in the middle section, the granular ceramic 112 also causes friction and / or collision, amplifying the ionic effect. Since the granular ceramic 112 has a smaller particle size than the granular ceramic 113 stored in the lower section, by passing water through the middle section from the bottom to the upper side, the granular ceramic 112 is sufficiently mixed with the large granular ceramic 113. A desired ionic effect can be exerted on water that has passed through the gap without contact. And finally, by passing water through the section filled with the granular granular ceramic 111 having the smallest particle size of the upper layer, the water is surely brought into contact with the granular ceramic 111 and the ionic effect is reliably exerted. Can be. Therefore, such granular ceramics 111, 11
Due to the synergistic effect of the three-layer compartment containing 2,113
The ion effect can be further enhanced.

Next, the configuration of the cartridge 12 will be described. The cartridge 12 whose main purpose is to provide at least a mineral component is filled with a quartz diorite limestone (so-called Io stone) 121 having an average particle size of 5 mm to 7 mm, which is a water-permeable material, in a water-permeable material storage section. I do. A convex lens 122 is fixed on the upper part of the cartridge 12.
Of the metal material 1 by the upper support 125 located just below
23 and the metal material 124 are fixed. A shaft pipe 44 is provided at the center of the shaft of the cartridge 12, and an upper support 125 for supporting metal materials 123 and 124 is provided at an upper end of the shaft pipe 44.

The convex lens 122 is a hemispherical convex lens, and the metal members 123 and 124 are a pair of dissimilar metal materials having one end embedded and fixed in the convex lens 122 and extending in a bar shape while maintaining a predetermined interval. A pair of dissimilar metal materials 12
Reference numerals 3 and 124 denote different kinds of metal materials having different ionization energies, preferably, a gold rod or a metal rod having at least a surface plated with gold, and a silver rod or a metal having a silver plated surface. Consists of a combination with a stick. The metal members 123 and 124 both penetrate through the upper support 125 and are supported by the upper support 125. Further, in the upper part of the cartridge 12,
The upper part of the convex lens 122 is exposed outside the cartridge 12, and the bottom surface is exposed inside the cartridge 12.

According to the cartridge 12 having the above structure,
The water that has passed through the layer of quartz diorenite 121 changes from ascending flow to descending flow in the upper gap of the cartridge 12 and descends in the shaft pipe 44. Since a pair of dissimilar metal materials 123 and 124 having different ionization energies are arranged in a non-contact state in the upper gap and the shaft pipe 44, when water passes therethrough, the ionization energy generated between the dissimilar metal materials is reduced. Utilization can be used to ionize water to enhance the antibacterial effect (the effect of suppressing the growth of various bacteria).

In particular, according to the example of the cartridge 12, since the convex lens 122 is exposed outside the cartridge,
With this convex lens 122, the light beam outside the cartridge can be focused on at least a part of the pair of dissimilar metal materials 123 and 124. As a result, the ionizing energy can be amplified by converging the light beam outside the cartridge and capturing a small amount of infrared light into the cartridge and applying thermal energy to the pair of dissimilar metal materials 123 and 124.

The above operation will be described in detail by taking as an example a case where gold and silver are selected as the material of the pair of dissimilar metal materials. The ionization energy of gold (value for monovalent ions) is 9.23 eV, and the ionization energy of silver (value for monovalent ions) is 7.58 eV. Therefore, the difference in ionization energy generated between both metals is 9.23
(EV) −7.58 (eV) = 1.65 (eV), but this value changes depending on the surrounding environment. Utilizing this property, the convex lens 122 converges the light beam outside the cartridge and captures a small amount of infrared light into the cartridge, and imparts thermal energy to the dissimilar metal material of gold and silver, whereby ionization energy is amplified. Thus, the thermal conductivity of gold (315 W / m · K) and the thermal conductivity of silver (427
W / m · K), the difference in the ionization energies is larger, but the cooling action takes place by passing water through the portion where gold and silver have accumulated heat energy, and the ionization energy generated between the two metals Is amplified. As a result, water only passes between the two metals,
The antibacterial effect can be enhanced by ionizing water. The metal members 123 and 124 are not limited to being made of metal, but may be replaced with a bar made of resin or ceramic plated with gold or silver, as long as the above-mentioned effects are exhibited.

In the water purifier 1 configured as described above, when tap water is supplied from the intake pipe connecting portion 261, the tap water is introduced into the cartridge 5 and the coconut shell activated carbon 5
4 and calcium sulfite 55 remove the chlorine odor and turbidity due to residual chlorine in the water, and are discharged from the cartridge 5. The water discharged from the cartridge 5 is introduced into the cartridge 11. Then, suspended substances and water-soluble substances in water are removed by the ionic effect, physicochemical action, and biochemical purification action of the granular ceramics 111, 112, and 113, and the granular ceramics 111, 112, and 113 are discharged from the cartridge 11. Further, the water discharged from the cartridge 11 is introduced into the cartridge 12 and is given a mineral component by the quartz diorite rock 121, and the ionic effect of the metal materials 123 and 124 is added, and the water is discharged from the purified water discharge pipe 8. You.

That is, the water purifier 1 shown in FIG. 11 removes the odor of tap water and foreign matters floating or dissolved in water, and then adds a mineral component to generate purified water. The water purifier 1 is used daily at home or the like, and is covered with a case cover 10 for avoiding dust and the like. The case cover 10 is preferably a transparent or translucent resin, such as a transparent or translucent resin, that transmits light at a predetermined level or more, in order to keep the amount of light incident on the convex lens 122 of the cartridge 12 at a predetermined level or more.

As described above, the water purifier 1 can be used as a water purifier for daily life by mounting a cartridge other than the pump cartridge 3 on the receiving portions 23, 24, and 25 of the gantry 2. In an emergency such as a disaster, as shown in FIG. 1, the pump cartridge 3 is mounted on the receiving portion 23, the cartridge 4 is mounted on the receiving portion 24, and the cartridge 5 is moved to the receiving portion 25. By manual operation of the cartridge 3, the cartridge 3 can be used as a water purifier for producing drinking water from unsuitable raw water. As described above, since the water purifier 1 is useful both in daily life and in an emergency, it is not necessary to secure a special storage place.

Further, in the water purifier 1 shown in FIG. 1, the pump cartridge 3, the cartridge 4, and the cartridge 5 mounted on the gantry 2 are provided with stop valves 35, 35a, 3
Although the stop valves 5b and 35c are provided, these stop valves are effective when the unpurified raw water is pumped by the pump cartridge 3 and purified. On the other hand, FIG.
Since the water purifier 1 shown in Fig. 11 is connected to a water pipe, it can be used without providing a stop valve in each cartridge shown in Fig. 11. In the present embodiment, the pump cartridge 3 and the cartridges 4 and 5 of the water purifier 1 shown in FIG. 1 are provided with stop valves 35, 35a, 35b and 35c inside the cartridge, and the gantry 2 is similar to the stop valve 35. No stop valve is provided. For this reason, only in an emergency where a stop valve is required, high reliability in terms of hygiene is secured by using the stop valve, so that the cost of the gantry 2 and each cartridge shown in FIG. 11 can be reduced. .

In the above embodiment, the water purifier 1 is provided with a non-woven cloth filter 33, a prefilter 42, a hollow fiber membrane filter 43, coconut shell activated carbon 54, calcium sulfite 55, , 112, 113, quartz diorenite 121, etc., but the present invention is not limited to this. For example, paper, non-woven cloth, non-woven cloth using natural fibers or synthetic resin fibers , Hollow fiber membranes, filter materials such as sponges and sponges, ion exchange resins, those that decompose organic substances in water by catalysis, and those that purify water by filtering after aggregating foreign substances in water with a coagulant For example, the present invention can be applied as long as it is used for water purification. In addition, the present invention is not limited to the above-described embodiment in regard to other detailed configurations and the like, and various changes can be made without departing from the spirit of the technical idea described in the claims. Needless to say.

[0104]

As described above, according to the present invention, the following useful effects can be obtained.

According to the first aspect of the present invention, there is provided a main body having an intake port to which raw water is supplied, and a water-passage treatment section in which a water-passage treatment material for purifying water when passing water is accommodated in a case. , A pressure feed unit for applying pressure to raw water supplied from an intake port of the main body and passing the raw water through the water flow processing unit, and the water flow processing unit and the pressure feed unit are configured to be detachable from the main body. In some cases, the water treatment section and the pumping section can be detached from the main body and stored. Thus, storage during normal times, that is, when not in use, is convenient. Further, the water purifier according to the present invention applies pressure to the raw water to force the water to pass through the water passage treatment section, so that a large amount of raw water can be quickly purified.
Therefore, it is possible to provide a water purifier that is convenient for storage and has high production capacity for drinking water.

According to the second aspect of the present invention, the main body is provided with at least one pedestal that can be attached to any of the water passage processing section and the pressure feeding section. By properly selecting the pumping section and mounting it on the base,
It can be used as a water purifier for purifying tap water in daily life or as a water purifier that can obtain drinking water from unsuitable drinking water in an emergency. This makes it possible to provide a highly convenient water purifier that can be effectively used even during normal times. In addition, since only the pumping unit and the spare water passage processing unit need be stored in case of an emergency, it is possible to save labor for storage.

According to the third aspect of the present invention, the main body is provided with a plurality of pedestals, and a fitting portion that fits into the pedestal of the main body is disposed on the case of the water-passage processing section and the exterior of the pumping section. Therefore, any of the water-passage processing section and the pressure feeding section can be attached to the plurality of pedestals of the main body. Thereby, in the plurality of pedestals of the main body, the position where the pumping unit and the water treatment unit are mounted and the number of the pumping unit and the water treatment unit to be mounted can be appropriately changed, so that it can be effectively used even in normal times and the convenience is improved.
