Abstract

PURPOSE:To improve water purification efficiency and also to reduce load on a motor for rotating a water purifier by making permeation length of a purifying filter large. CONSTITUTION:Water is subjected to convection by rotation of a water purifying filter formed with permeation ports of water to the upper part and the lower part and water is allowed to permeate to the vertical direction in the inside of the water purifying filter. For example, a permeation port 38 for suction is formed to the upper part of the water purifying filter 24 and a permeation port 34 for discharge is formed to the lower part thereof and a motor 2 is driven to rotate the water purifying filter and water is subjected to convection and thereby water is permeated to the vertical direction in the inside of the water purifying filter 24. As a result, water purification efficiency can be improved and the diameter of the filter 24 is made small and thereby load on the motor 2 can be reduced.

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention relates to a water purification device for purifying tap water or well water.

(b) Conventional technology In the past, as this type of water purification device, for example,
The one shown in Japanese Patent No. 982 is known. This water purification device is attached to a tap and purifies the tap water that comes out of the tap by passing through it only once, so it cannot sufficiently remove chlorine odor, etc., and has the disadvantage of poor water purification efficiency.

In order to solve the above-mentioned problems, the present applicant has filed a patent application filed in 1983-
No. 218596 was proposed. This configuration is shown in Figures 9 and 1.
To explain based on the θ diagram, (l) is the base that houses the electric motor (2). A 7IK# connector (3) is arranged on the upper part of the top surface.

(4) is a bottle stand made of synthetic resin that is removably placed on the base (1), and has a threaded portion (6) integrally formed in its upper part. A rotary shaft (6) passing through a substantially central portion of the bottom of the bottle stand (4) is rotatably supported via a bearing (7), and a lower end of the rotary shaft (6) is engaged with the connector i3J. The connector (8) is firmly attached.

(9) is a substantially cylindrical glass bottle with openings on the top and bottom, and a threaded part formed at the opening on the bottom. This threaded part f
101 is screwed onto the threaded part (5) of the bottle stand (4) to integrate it with the bottle stand (4), and the bottle stand (4) and bottle (9) are integrated.
The container is made up of:

(The water purification filter is detachably attached to the upper part of the rotating shaft +61, and is composed of a synthetic resin filter frame 0, a pair of main filters (13), and a deodorizer (I4).

The filter frame (+2+ is integrally formed with the outward part of the disc part (1[9 and this disc part 06), and has a substantially n-shaped cross section that stands upwardly. The frame body part θ→ has a suction permeation port (lη
(hereinafter referred to as the suction port) and a discharge permeation port α barrel (
(hereinafter referred to as a discharge port) is provided in a protruding manner.

The main filter a'4 is mounted within the frame body part 0 of the filter frame σ to cover the suction port aη and the discharge port α, and is made of foamed resin, sintered resin, or the like. The deodorizing agent a is filled in the filter frame α and in the main filter 03, and is made of granular activated carbon.

- is a lid made of synthetic resin that covers the top opening of the bottle; 9).

Then, put the required amount of tap water or well water into the container consisting of the bottle stand (4) and the bottle (9), and
) Close the top opening with the lid (II) and attach it to the base fl.
Place it on j. When the electric motor (2) is driven, the water filter () rotates, and the water (a) rises along the G111 surface inside the bottle (9) as shown by the arrow (b) in Figure 9.
Water purification filter (1) creates convection that falls approximately in the center,
Due to this convection, suction port 1 + η → main filter 〇3 →
The water passes through the water purification filter (river) many times through the deodorizer ring → main filter +131- + discharge port Q barrel, and passes through the water purification filter (river) many times.During this permeation process, the main filter contains dirt, iron rust, etc. is attached and removed, and the deodorizer t14 removes chlorine odor, mold odor, and bitterness.

However, the above-mentioned water purification filter is formed in an annular shape, and has an inlet αη on the inner surface and an outlet (181) on the outer surface to allow water to pass through in the centrifugal direction. Although it is not necessary to increase the outer diameter in order to increase the water purification efficiency, if the outer diameter of the water purification filter (I) is made large, the load applied to the motor 2 that drives the water purification filter will increase. Grow,'rI!t
# There was a drawback that the life of the machine was shortened.

(c) Problems to be Solved by the Invention The present invention has been made in view of the above-mentioned problems, and is capable of improving water purification efficiency by increasing the length of water permeation, and does not shorten the lifespan of 1 tvj water purification. The purpose is to provide equipment.

Ninth means to solve the problem In order to achieve the above purpose, the water purification filter is formed with water permeation ports at the upper and lower parts, and the water purification filter is
Convection of water is created to allow water to permeate vertically inside the water purification filter.

(E) Function Since it is configured as described above, when tap water or well water is poured into the container and the water purification filter is rotated by an electric machine, the water flows through convection and is sucked in from either the upper or lower permeation port. , passes through the inside of the water purifying filter in the vertical direction and is released from the other permeation port. Water is purified by passing through the water filter many times by convection.

Since water is configured to pass through the water filter in the vertical direction, the height of the water filter can be increased, the length of water filter transmission can be increased, water purification efficiency can be improved, and the diameter of the water filter can be reduced. And electric wtjJ
The load on Ifs can be reduced.

(F) Embodiment An embodiment of the present invention will be described in detail below with reference to FIGS. 1 to 5. Note that the same reference numerals as in the conventional example represent the same parts, so the explanation will be omitted.

(2I is a rotating shaft that is rotatably supported via a bearing (7) at the bottom center of the bottle stand (4), and an electric motor (2
) is fixed with a connector (8) that engages with the connector (3) of the connector (3). On the #1 rotating shaft (toward), a retaining pin is protruded from the lower part of the upper part of the +17 bottle stand (4), and a small diameter part is formed at the upper part, and a small diameter part is formed at the upper end of the small diameter part. It forms a stepped part with a slightly larger diameter than the part.

Another is the water purification filter that is removably attached to the top of the rotating shaft (a), and is made of a resin filter frame. It consists of a pair of main filters (to) and a deodorizer (5).

First, to explain the filter frame f2 [flK, the frame is a box-shaped main frame with a bottom, and the main frame (28i) is rotated from the approximate center of the bottom to form a fitting part into which the rotating shaft is inserted and fitted. A locking pin 21 for the rotating shaft is provided at the bottom of the four outer parts.
) is formed, and by the engagement of this engagement pin υ and engagement S (a), the water purifying filter 41i tar @4 is formed.
1 is fixed and prevented from rotating.

A bulge G31 having a slightly larger diameter than the stepped portion A of the rotating shaft is formed in the fitting portion 4, and a U-shaped portion is formed between the upper surface of the bulge 3η and the upper frame (to be described later). A locking spring (2) is clamped and fixed. This locking spring (to) is formed to have a smaller diameter than the step opening of the rotating shaft.
), the locking spring (-) passes over the stepped portion (c) and comes into elastic contact with the small-diameter portion (-), thereby preventing the water purifying filter from lifting up. In addition, the fitting unit is equipped with a rotating shaft (A) that allows air to be sucked in from the intake port (7) of the upper frame (■), which will be described later.
A space surrounded by the main frame □□□ and the fitting unit is formed through the periphery of the water filter, that is, a ventilation path that guides the inside of the water purifying filter downward without passing through it. (to) are a plurality of discharge permeation ports (hereinafter referred to as discharge ports) bored in the bottom of the main frame (c), and between the discharge ports (b) are blades that extend downward from the bottom of the main frame (to). Dirt 2 (To) is formed.

(to) is an upper frame that is welded and fixed to the upper edge of the upper surface of the main frame (2 to 2~) and the upper end between the parts f to cover the upper surface of the main frame μs, and a recess (2) is formed in the center. The recess has a side surface that slopes upward from the bottom of the recess toward the external gyrus so that the opening expands upward, and a suction permeation port (hereinafter referred to as the suction port) that is recessed on the screen. The above-mentioned ventilation IN! It communicates with (to).

The chrysanthemum is a lower frame that is welded and fixed to the lower part of the main frame (C), and is in contact with the lower end of the wing piece (7) of the main frame (C), leaving a distance between it and the discharge port (to) of the main frame. The space between the holes is opened on the side surface of the lower part of the water purifying filter threshold to discharge Mi4υ.

The main filter rod is installed inside the filter frame □□□, and is designed to cover the suction port and the discharge port (to) of the filter frame (B), and is made of foamed resin, sintered resin, etc. It has extremely small pores of less than a micron. The deodorizing agent is made of granular activated carbon and is filled within the filter frame and into the main filter. The diameter of the pores in the main filter is set to A x B, where A1 is the particle diameter of the deodorizing agent, and B is set to prevent deodorizing particles from leaking through the pores of the main filter.

Next, to explain the operation, the bottle (9) and the bottle stand (4)
A required amount of tap water or well water is poured into a container constructed of , the top opening of the bottle (9) is mid-closed at the end of the lid, and the bottle is placed on the base (1). When the electric motor (2) is driven, the water purification filter (24) rotates, and the water (d) is pumped into the bottle (as shown by the arrow (e) in Fig. 1) by the wing pieces (7).
9) Convection is generated that rises along the inner surface and falls to the top of the water purification filter (b). This convection causes the water to flow through the inlet (
)→Main filter ＼→Deodorizer＠→Main filter 翼→Discharge port (to)→Discharge path←υ and passes through the water purification filter (goods) many times. During this permeation process, dirt and iron rust contained in the water adhere to the pores of the main filter screen and are removed, followed by deodorization to remove chlorine, mold, and bitter odors.

The water filter (24I) has an inlet at the top and an outlet at the bottom, allowing water to pass through in the vertical direction, so the outer diameter of the water filter can be made smaller. The load applied to the electric motor (2) can be reduced, the life of the 'fItr machine (2) can be increased, and the height of the water purification filter (goods) can be increased to thicken the layer of deodorizing punishment.
It is possible to efficiently remove chlorine odor, etc.

In addition, in the conventional structure shown in Figures #I9 and 10, the inner surface of the water purification filter (!) where the suction port aη is formed is approximately vertical, so a large amount of air flows through the suction port αη. There is a drawback that the amount of water sucked in through the suction port a7) decreases, resulting in a decrease in water purification efficiency.

To explain in detail, the rotation of the water purification filter (11) causes the water (
a) rises along the inner surface of the bottle (9) and falls in a spiral shape at the center of the water filter (1), causing a convection (b) t-; An air layer (C) is generated.Water filter +I
When +3 rotates quickly or when the amount of water in the container is small, the air layer (c) reaches into the recess surrounded by the inner surface of the water purifying filter (■), as shown in FIG. Water (a
) falls in a spiral shape into the recess in the center, but since the inner surface of the water filter ill is formed vertically, the upper part of the inner surface blocks the falling water flow (b'). , turbulent flow (b) occurs, entraining air, and the air is sucked in from the suction port αη.Therefore, the amount of water that passes through the water purification filter (I1) is reduced by the air, and the water purification efficiency is improved. There was a drawback that it deteriorated.

On the other hand, the water purification filter (support) of the wooden embodiment has a concave IMII which forms the suction port (end)! Since the I side is formed upward and inclined toward the cutting direction, the upper part of the concave Fyr (b) side surface does not block the flow (e) of water (d), and the water (d) It is sucked in smoothly from the suction port. Therefore, the water (d) does not involve air, and the amount of air sucked in from the suction port can be reduced.

In addition, air (g) is sucked in from the intake port (g) at the rotation center of the water purification filter (to), passes through the ventilation 53 (to), and is released from the bottom of the water purification filter without passing through the inside of the water purification filter. .

To be more specific, at the beginning of rotation of the example water filter,
The water does not have stable convection, and the water filter (24
The air layer generated at the rotation center of the water filter FF14
1 concave FrgI) does not reach the bottom. In this state, the ventilation fjI is
The water in rQ is released from below, and the same amount of water as the released water is sucked in from the intake port.

When the convection of water becomes stable, the air In(g) generated at the rotation center of the water purifying filter f241 reaches the bottom of the concave Fifr@ as shown in FIG. In this state, the rotation of the water purifying filter 1241 causes the water in the air passage (to) to be discharged from below, and the same amount of air as the volume of the discharged water is sucked into the air passage q from the intake port (g). Then, the air in the ventilation path (to) is also released from below, and the same amount of air as the volume of the released air flows from the air intake port (g) into the ventilation path a.
sucked inside.

Due to the convection of water, the air m (g) also moves downward, but the air is sucked in from the intake port (to) and released through the air passage (to) without passing through the inside of the water purification filter. The water purification efficiency can be improved by further reducing the amount of air sucked in from the suction port (to) of the water purification filter (3) and increasing the amount of water passing through the inside of the water purification filter.

When replacing the water filter because it becomes dirty, pull the water filter upwards, the locking spring (to) will deform, and the locking spring (to) will rotate over the stepped part of the rotating shaft. The connection with the shaft is lost. . Pull out the water purification filter (241 from rotation@4), remove the new water purification filter from the rotation shaft, and attach it by reversing the operation.

FIG. 6 shows another embodiment, in which the upper surface of the filter frame is formed flat and a suction port is provided at the outer periphery of the upper surface.

In this configuration, water that has fallen onto the top surface of the water filter □□□ is sucked in from the suction port □□□, so the liquid level (d)
suddenly spreads to the outer periphery on the upper surface of the water filter (2). The air layer (g
) also spreads to the outside on the top surface of the water purification filter, and since air has a lower permeation resistance than water, air is sucked in from the suction port (to) as shown by arrow g' in Figure 6, and permeates through the water purification filter. The amount of water used decreases, and water purification efficiency decreases.

Therefore, in the configuration in which the top surface of the water purification filter (24j) is formed flat as described above, as shown in FIG. It is desirable to have direct communication with the air passage (G) which does not communicate with the inside of the filter I241.

FIG. 8 shows still another embodiment, in which the main frame (2B) of the filter frame is formed into a cylinder shape with a plurality of discharge ports (6) (hereinafter referred to as discharge ports) formed in the top surface. A wing piece (not shown) is bored in the discharge port (44) upward from the top surface. This interval is used for water purification filters (
2. A discharge channel (441) is opened on the upper side surface of the casing.

The lower frame has multiple suction holes (hereinafter referred to as suction ports).
is installed.

Then, when the water purification filter circle is rotated, the blade permeation port (
)→The water passes through the water purification filter 20 many times through the discharge path (41). In this configuration, water is sucked in from the lower part of the water purifying filter 2υ and discharged from the upper part, so air is not drawn in, and therefore there is no need to provide an intake port or a ventilation path.

(G) Effects of the Invention As described above, according to the present invention, the water purification filter is formed with permeation ports in the upper and lower parts thereof, and water is allowed to permeate in the vertical direction inside the water purification filter, so that the diameter of the water purification filter can be reduced. The load applied to the electric motor can be reduced to extend the life of the electric motor, and the height of the water purification filter can be increased to improve water purification efficiency. The side surface of the recess on the top surface of the water filter is turned upward and tilted outward, and a permeation port for water suction is formed on the side surface of the recess, thereby reducing the amount of air that passes through the inside of the filter and increasing the amount of water permeation. In addition, since the air intake port is provided on the upper surface of the rotation center of the water purification filter, and this air intake port is communicated with the air passage that does not communicate with the inside of the water purification filter, the amount of air passing through the inside of the water purification filter can be increased. It is possible to reduce the amount of water permeated and increase the amount of water permeated, which has the effect of improving water purification efficiency.
