Description

Filter base for water purifier

The present invention relates to a filter base for water purifiers, and more particularly, to a filter base for allowing a filter to be replaced or for fixing a filter.

Recently, due to the increasing interest in pollution and health due to industrialization, interest in drinking water, which is drinking water, is increasing. In the midst of this trend, one of the devices that can easily eat clean drinking water is a water purifier. Another form of drinking water is to electrolyze purified water to provide alkaline reduced water. It is an ionized water group to prepare and provide such alkaline reduced water.

Such a conventional water purifier and an ionizer are provided with a filter inside. These filters are divided into a primary filter and a secondary filter to perform different filter functions. In addition, the filter has a fixed life, and should be replaced with a new one after a period of use.

At this time, to replace the filter, remove the case and replace the filter installed in the filter base with a new one. Thus, the filter base is provided with a number of connectors and ports.

However, such a conventional filter base has the following problems.

First, the connection between a number of connectors and ports is made by connecting individual parts, so the number of parts is large, and the assembly of the filter base takes a lot of time. There was this.

Second, since the conventional filter base is produced in a form for fixing only two filters, there is no compatibility in a model requiring only one filter or a model requiring three or more filters.

Third, since the inside of the conventional water purifier or ionizer was narrow, the cylindrical filter was inserted and replaced from the top to the bottom. Therefore, it was very inconvenient for replacement, repair, cleaning, etc., because the hand did not go deep inside the hole where the filter was inserted.

Accordingly, the present invention has been made to solve the above problems, the first object of the present invention is to provide a filter base with high productivity without fear of leakage by molding integrally through plastic injection, the number of parts is small. .

A second object of the present invention is to provide a filter base capable of connecting one or two or more filter bases in series according to design requirements.

The third object of the present invention is to provide a filter base that can be easily replaced or repaired by rotating or separating the filter base only when the filter is replaced, since the structure is detachable and rotatable between the filter bases connected in series. .

According to an aspect of the present invention,

The filter inserting portion 120 into which the replaceable filter 30 is fitted on one surface is recessed,

Inside,

A first flow path 200 having one end formed with a first connector 150 and a first port 160 formed at the other end; and

A second flow path 210 having one end formed with a second port 130 and a second connector 140 formed at the other end thereof;

The first connector 150 may be achieved by a filter base for a water purifier, which may be detachably fitted to the second connector 140 of another filter base.

In addition, the second port 130 may be formed at the center of the filter insertion part 120, and the first port 160 may be formed around the second port 130.

In addition, the first connector 150 and the second connector 140 of another filter base are rotatable in a fitted state.

In addition, an internal thread portion 110 for fixing the filter 30 is formed on the inner circumferential surface of the filter inserting portion 120.

In addition, at least one of the first flow path 200 and the second flow path 210 may have a shape bent at 90 degrees.

In addition, the first connector 150 and the second connector 140 are preferably located on the same axis.

The outer appearance of the filter base is more preferably cylindrical.

In addition, the filter base is most preferably formed integrally by injection molding.

In addition, after the water entering the first flow path 200 is treated in the filter 30 through the first port 160, it is discharged to the second flow path 210 through the second port 130. It is possible.

In addition, the plurality of filter bases may be connected in series using the first and second connectors 150 and 140, and the filter 30 having the same or different performance may be fitted into each filter inserting unit 120.

According to one embodiment of the present invention as described above, there is no fear of leakage by integrally molding through plastic injection, the number of parts is small, the productivity is high. That is, it has a long life, hygienic and high productivity.

And, depending on design requirements, one or two or more filter bases can be connected in series. Therefore, a low mold cost is attained corresponding to various models. In addition, a separate piping work is unnecessary just by interconnecting the filter bases.

In addition, since the structure is detachable and rotatable between the filter base connected in series, it is possible to easily replace or repair the filter by rotating or separating only the filter base when replacing the filter.

As shown in FIG. 1, the filter inserting portion 120 into which the filter 30 may be inserted is recessed on the upper surface of the cylindrical filter base 100. Since the filter 30 has a cylindrical shape, the cylindrical filter base 100 can efficiently utilize the space inside the water purifier.

The female screw part 110 is formed along the inner circumferential surface of the filter inserting part 120. Accordingly, a male thread part (not shown) formed in the filter 30 is fitted to the female thread part 110 to fix the filter 30 to the filter base 100.

The second port 130 is formed to protrude to a predetermined height in the central region of the filter inserting portion 120. The second port 130 functions to allow the purified water from the filter 30 to flow out to the second connector 140.

The second connector 140 is in communication with the second port 130. The second connector 140 protrudes from the side surface of the filter base 100 by a predetermined length, and a minute protrusion (not shown) is formed at an end thereof so that the second connector 140 can be detachably attached to the first connector 150.

FIG. 2 is a bottom perspective view of the filter base for water purifier shown in FIG. 1. As shown in FIG. 2, first and second flow paths 200 and 210 are formed in the filter base 100. That is, the first and second connectors 150 and 140 and the first and second flow paths 200 and 210 are arranged in a straight line shape.

The filter base 100 is integrally formed through injection molding of plastic resin.

3 is a front sectional view of the filter base for water purifier shown in FIG. As shown in FIG. 3, the first connector 150 is connected to the first flow path 200, and a first port 160 is formed at an end thereof. In addition, the intermediate region of the first flow path 200 is bent upward at an angle of 90 degrees so that water easily enters the filter 30.

The second port 130 is connected to one end of the second flow path 210, the middle region is bent upward at an angle of 90 degrees, and the second connector 140 is formed at the other end.

The first connector 150 may be connected to a connection pipe obtained as a water supply, or may be connected to the second connector 140 of another filter base 100.

The first port 160 is formed on the bottom surface of one side of the roundly inserted filter insert 120, and has a configuration for connecting with the first filter port 34. For reference, the first filter port 34 is a water inlet for water to be purified, and is formed in an annular shape around the second filter port 32. The second filter port 32 functions as a circular hole formed in the center to discharge purified water out of the filter 30.

The second port 130 protrudes to a predetermined height in the center region of the filter inserting part 120 and functions to connect the second filter port 32 and the second flow path 210.

The intermediate regions of the first and second flow paths 200 and 210 are bent to allow the purified water to flow horizontally with respect to the filter 30 installed vertically.

4 is a front view of a state in which the filter base for water purifier shown in FIG. 1 is continuously connected. As shown in FIG. 4, two or more filter bases may be connected in series. That is, the second connector 140 of the filter base 100A is connected to the first connector 150 of the filter base 100B. As the connection method, a simple insertion and fixing method using a protrusion is used, but various other methods (eg, quick coupling, etc.) may be applied. In the same manner as in FIG. 4, three or more filter bases 100 may be connected in series, and each filter base 100 may be provided with the same filter or different filters (eg, activated carbon filter, hollow fiber membrane filter, ion filter, etc.). Can be installed.

As shown in FIG. 5, the first and second connectors 150 and 140 have two modes connected or separated in the axial direction, but are not limited in the relative rotation direction. Therefore, the filter base 100B may be rotated by a desired angle (eg, 30 degrees, 45 degrees, 90 degrees, etc.). O-ring and the like may be fitted between the first and second connectors 150 and 140 for such a waterproof and rotating structure. Through such relative rotation, only the desired filter base 100 may be turned, and then the filter 30 may be replaced.

<Operation>

Hereinafter, the operation of the filter base for water purifier having the above configuration will be described. First, the filter 30 is inserted into the filter insertion unit 120 and then rotated so that a screw coupling is performed to the female screw unit 110. Then, as shown in FIG. 3, the second filter port 32 is tightly fixed to the second port 130, and the first filter port 34 is tightly fixed to the circumferential surface of the filter insertion part 120.

Water entering the first connector 150 is changed by 90 degrees in the first flow path 200, and then fills the empty space of the filter inserting part 120 through the first port 160. Then, the filter 30 enters through the annular first filter port 34 and is filtered.

The filtered water descends the second filter port 32 to the second port 130 and continues to move through the second flow path 210 and the second connector 140.

At this time, if necessary, if another filter base 100B is connected, the same type of filtration and flow will be repeated. The water exiting the last filter base 100 is then received in a tank (not shown) or provided as drinking water through an instantaneous heating, instant cooling or ionization process.
