Description

Rotary combined water purification system filter head with bypass path {FILTER HEAD FOR WATER PURIFYING SYSTEM WITH BY-PASS LINE}

The present invention relates to a filter head for a rotary-coupled water purification system having a bypass path, and more particularly, it can supply raw water by switching it to a filtering or bypass state according to the state of a bypass valve, and can be replaced inside the water purifier It relates to a rotation-coupled water purification system filter head having a bypass path that enables detachment and attachment only by rotating the installed filter by a certain angle so that water leakage or failure does not occur even when high water pressure is applied.

In modern society, as distrust of tap water increases due to water pollution, more and more consumers use purified water with water purifiers or use bottled water as drinking water, and this trend continues to increase in the future.

A water purifier usually used is composed of at least one filter that removes foreign substances contained in raw water obtained through an inlet and discharges purified water, and an outlet that discharges purified water out of the system.

In the filters of these water purification systems, if a certain amount of water is purified for a certain period of time or a certain amount of water, impurities contained in the water passing through the filter are loaded into the filter and the purification ability is reduced. .

Existing filter replacement of these water purification systems is to connect the supporter and filter in the form of female or male threads, or connect the filter and filter or the connecting hose and fitting used to connect the filter and the supporter using a separate mechanism. In order to block the outflow of raw water, the process of directly blocking the raw water using the raw water shutoff device, replacing the filter, and then adjusting the raw water shutoff device is required, so there is a problem in that workability is poor and complicated.

The filter head 100 of the present invention is configured to be detachably coupled to a separate filter 200, and the filter head 100 is installed inside the water purifier. The filter 200 is a consumable item, and is provided so that it can be replaced after use in a certain amount or for a certain period of time.

The filter head 100 is installed in the water movement path installed inside the water purifier. In general, the water purifier includes a part that receives raw water (water before purification) from an external water inlet pipe or a raw water tank, and a part that discharges purified water from which foreign substances are removed by the filter 200 . The filter head 100 is installed in such a water movement path to guide raw water supplied from the outside into the purified space of the filter 200 , and guides purified water that has been cleaned by filtering foreign substances from the filter 200 to the outside.

In addition, the filter head 100 of the present invention has a function of adjusting the movement path so that the raw water does not flow into the filter 200 and directly passes (bypass). Preferably, the amount of raw water introduced into the filter 200 and filtered, and the amount of raw water passing along the bypass path can be relatively adjusted. That is, by adjusting the amount of filtered raw water from 0% to 100%, the amount of bypassed raw water can be changed from 100% to 0%.

The filter head 100 is preferably installed on the outside of the water purifier body so that an operator or user can easily operate it, and rotate the filter head 100 outward to facilitate the operation of rotating the filter 200 . installed so that

On the left and right sides of the outer surface of the filter head 100, a connector for introducing and discharging water into and out of the filter head 100 is provided. The connector is connected to a flow path formed inside the filter head 100 .

In the present invention, it is configured to have a coupling structure so that a plurality of filter heads 100 can be continuously connected and used. That is, a connector through which the raw water or purified water discharged from the filter head 100 is introduced is separately provided, and a connector through which the raw water or purified water is discharged is separately provided.

In addition, a bypass valve 122 is provided on the upper surface or the front surface of the filter head 100 to control the amount of filtered raw water and bypassed raw water. The bypass valve 122 selectively opens and closes an independent raw water movement path formed inside the filter head 100 to change the amount of raw water introduced into the filter 200 and the amount of raw water discharged without a purification process.

And a structure for fixing the filter 200 is formed on one surface of the filter head 100 . The fixing structure may be formed on the bottom or side surface of the filter head 100 .

In the present invention, the place where the filter 200 is coupled is described by referring to the "bottom, side" of the filter head 100, but the bottom or side of the filter head 100 inside the water purifier does not necessarily face downward or to the side. No, it may be installed upwards.

A first connector 104 , a second connector 106 , a third connector 108 , and a fourth connector 110 are provided on both sides of the filter head 100 forming the outer shape of the filter head 100 , respectively. In the drawings of the present invention, the first connector 104 and the third connector 108 are formed on the left side, and the second connector 106 and the fourth connector 110 are formed on the right side.

A first connector 124 connecting the first connector 104 and the second connector 106 is installed inside the filter head 100 , and the third connector 108 and the fourth connector 110 are connected A second connection pipe 126 is installed. And the first connecting pipe 124 and the second connecting pipe 126 are connected to each other by the third connecting pipe (128). If there is no operation of the valve, the water introduced through the first connector 104 is discharged through the second connector 106 , and the water introduced through the third connector 108 is discharged through the fourth connector 110 . is emitted However, depending on the state of the bypass valve 122 , the water introduced through the first connector 104 may be divided and discharged through the second connector 106 and the fourth connector 110 . To this end, the bypass valve 122 divides the water introduced through the first connector 104 into the filter 200 and the third connector 128 and discharges the water.

The bypass valve 122 may move all of the water introduced through the first connector 104 to the filter 200 through the first connector 124 to be purified. In addition, the bypass valve 122 may move some or all of the water to the second connection pipe 126 through the third connection pipe 128 and discharge it to the outside of the filter head 100 in an unpurified state. have. According to the control state of the bypass valve 122, 100% to 0% of the raw water moves to the filter 200 to be purified, and the remaining raw water is bypassed and discharged without being purified.

A pipe through which raw water is introduced or discharged and a pipe through which purified water is introduced or discharged are respectively connected to the first connector 104 to the fourth connector 110 . Depending on the type of installation, the first connector 104 and the third connector 108 become the inlet, and the second connector 106 and the fourth connector 110 become the outlet, but the opposite movement path is formed. You may be able to connect as much as possible.

On the inner edge of the filter head 100, a fixing guide 112 is formed to protrude by a predetermined height toward the inside. The fixing guide 112 has a space of a certain size formed therein, and the fixing blade 206 formed in the filter 200 is inserted therein. When the filter 200 is rotated to one side in a state coupled to the filter head 100 , the filter 200 is fixed to the filter head 100 while the fixed blade 206 moves to the inside of the fixing guide 112 . In some cases, it is also preferable to form a chin on the inner surface of the fixing guide 112 to prevent the fixing wing 206 from easily coming out.

A rotating plate 114 is rotatably installed on the lower surface of the filter head 100 . The rotating plate 114 is rotatably installed around a rotating shaft disposed in the vertical direction above and below the filter head 100 . The rotating plate 114 changes the position of the connecting pipe within a certain angular range while rotating together with the filter 200 .

A first head connection pipe 116 is installed on one side spaced apart from the center of the rotating plate 114 . And the second head connection pipe 118 is installed at the center of the rotating plate 114, and serves as a rotation shaft of the rotating plate 114 at the same time. The first head connection pipe 116 and the second head connection pipe 118 are respectively coupled to the first filter connection pipe 208 and the second filter connection pipe 210 installed in the filter 200 . Accordingly, water may move between the first head connection pipe 116 and the first filter connection pipe 208 , and between the second head connection pipe 118 and the second filter connection pipe 210 .

The first head connection pipe 116 and the second head connection pipe 118 are connected to the first connection pipe 124 formed inside the filter head 100 according to the rotational state. Among them, the second head connection pipe 118 is always connected to the first connection pipe 124 , but the first head connection pipe 116 is the first connection pipe 124 according to a change in the position of the rotating plate 114 . ) is optionally associated with That is, when the rotating plate 114 is rotated so that the first head connection pipe 116 and the second head connection pipe 118 are arranged in a direction coincident with the longitudinal direction of the first connection pipe 124 , the first connection pipe (124) is connected. However, when the rotating plate 114 rotates 90 degrees so that the first head connection pipe 116 and the second head connection pipe 118 are disposed in a direction that does not coincide with the longitudinal direction of the first connection pipe 124 , the first The connection between the head connection pipe 116 and the first connection pipe 124 is released, so that water does not move.

The fitting protrusion 120 is formed to protrude downward from the bottom surface of the filter head 100 to have a constant cross-sectional shape. The fitting protrusion 120 is a structure for using a filter suitable for each water purifier model, and is manufactured to have a unique shape. The fitting protrusion 120 has a uniform cross-sectional shape and is configured to be inserted into the upper structure of the filter 200 fitted from the bottom.

The fitting protrusion 120 is manufactured in different shapes according to the types of the filter head 100 and the filter 200, and the fitting protrusion 120 having a shape corresponding to the filter head 100 and the filter 200 corresponding to each other. is provided

A movement passage through which water moves is formed in the filter head 100 . The first connector 124 connects the first connector 104 and the second connector 106 . In addition, the second connector 126 connects the third connector 108 and the fourth connector 110 . Accordingly, the first connector 104 is connected to the first head connector 116 and the first filter connector 208 along the first connector 124 . And the second filter connector 210 is connected to the second head connector 118, the second head connector 118 is connected to the second connector 106 through the first connector 124.

The second head connection pipe 118 is connected to the center of the first connection pipe 124 . In addition, the first head connection pipe 116 is positioned where the filter 200 and the filter head 100 are not connected to the first connection pipe 124 in a separated state. Therefore, it cannot form a movement path of water.

However, in a state in which the filter 200 is coupled to the filter head 100 , the first head connection pipe 116 rotates while being connected to the first connection pipe 124 . In order to couple the filter 200 to the filter head 100, the first filter connection pipe 208 and the second filter connection pipe 210 are connected to the first head connection pipe 116 and the second head connection pipe 118, respectively. The filter 200 is rotated in a predetermined direction while being inserted in the . In the present invention, it is shown to be rotated by 90 degrees in a clockwise direction.

When the filter 200 is rotated by 90 degrees, the filter 200 is fixed while the fixed blade 206 is slidably inserted into the fixed guide 112 . Then, the first head connection pipe 116 in which the first filter connection pipe 208 is fitted is connected to the first connection pipe 124 while rotating by 90 degrees in the clockwise direction. Accordingly, a movement path of water may be formed.

As shown in FIG. 6 , a structure is provided inside the filter head 100 to introduce raw water into the filter 200 so that the water purification action occurs, or to bypass the raw water to pass it through without a water purification action.

A raw water supply passage 138 is formed on one side of the first connection pipe 124 in the vertical direction. The lower end of the raw water supply passage 138 is connected to the first head connection pipe 116 . And a bypass valve 122 is installed on the upper side of the raw water supply passage 138, and the control rod 130 is inserted therein to be movable up and down. The control rod 130 adjusts the opening and closing state of the raw water supply passage 138 while moving up and down according to the rotational direction of the bypass valve 122 .

A closing part 132 is provided at the lower end of the control rod 130 . The closing part 132 seals or opens the space of the portion where the raw water supply passage 138 and the first head connection pipe 116 meet. To this end, the diameter of the closing part 132 is configured to be larger than the diameter of the distal end of the raw water supply passage 138 . An O-ring 134 may be further provided on the surface of the closing part 132 for sealing.

When the closing part 132 descends downward, it descends to a position where the first head connection pipe 116 and the raw water supply passage 138 meet to block the passage. Due to this, the raw water introduced through the first connection pipe 124 is in a state in which it cannot enter the filter 200 .

The control rod 130 is in a state inserted into the rod moving passage 136 provided on the upper side of the raw water supply passage (138). One side of the rod moving passage 136 is connected to the third connecting pipe 128 .

7 and 8 show a state of bypassing the raw water.

When the administrator rotates the bypass valve 122 to set the 'bypass mode', the control rod 130 descends downward and the closing part 132 blocks the raw water supply passage 138 . At this time, the rod moving passage 136 and the first connector 124 are in a connected state, and the raw water introduced through the first connector 104 passes through the rod transfer passage 136 and flows into the third connector 128. . Since raw water entering the third connector 128 flows to the fourth connector 110 through the second connector 126 , the water purification action cannot occur in the filter 200 . In this state, the raw water is 100% bypassed.

And when the operator rotates the bypass valve 122 to raise the control rod 130 upward, the closing part 132 rises upward to the lower end of the rod moving passage 136 . Due to this, the connection between the first connecting pipe 124 and the rod moving passage 136 is blocked, so that raw water cannot enter the rod moving passage 136 . And the raw water supply passage 138 is in an open state.

Accordingly, the raw water introduced through the first connector 104 passes through the first connector 124 and the raw water supply passage 138 and flows into the filter 200 while moving to the first head connector 116 . The raw water introduced into the filter 200 flows into the second head connection pipe 118 after the purification process, and the introduced purified water passes through the first connection pipe 124 and is discharged to the second connection port 106 .

As described above, 100% of the raw water introduced into the filter head 100 is converted into purified water while passing through the filter 200 .

If, as shown in FIG. 10 , when the operator properly rotates the bypass valve 122 , the flow of raw water flows in the direction of the first head connection pipe 116 and the third connection pipe 128 according to the position of the control rod 130 . direction can be divided. Therefore, it is possible to properly divide the purified water discharge in the filtered state and the raw water discharge in the bypassed state. However, the amount of water introduced through the first connector 104 will be equal to the sum of the amount of purified water discharged through filtering and the amount of raw water discharged through bypass.

On the other hand, the filter 200, as shown in Figure 12, the stopper 204 is bonded to the upper side of the filter body 202 at the lower side, and fixed blades 206 are formed to protrude from both sides of the stopper 204. . A filtering member (not shown) for filtering foreign substances in the raw water is installed inside the filter body 202 .

A second filter connection pipe 210 is installed in the middle of the stopper 204 , and a first filter connection pipe 208 is installed at a place spaced apart from the second filter connection pipe 210 to one side. The second filter connection pipe 210 and the first filter connection pipe 208 serve as entrances and exits through which water enters or exits the filter body 202 . Depending on the water purification system, the second filter connecting pipe 210 may be the inlet or the first filter connecting pipe 208 may be the inlet.

One or two O-rings are installed in the second filter connection pipe 210 and the first filter connection pipe 208, respectively. Typically, the first filter connection pipe 208 and the second filter connection pipe 210 are configured to be respectively inserted into the first head connection pipe 116 and the second head connection pipe 118, so that the second filter connection pipe is connected. An O-ring is installed on the pipe 210 and the first filter connection pipe 208 . When the second filter connection tube 210 and the first filter connection tube 208 are larger and the first head connection tube 116 and the second head connection tube 118 are inserted, the O-ring is inserted into the first head connection tube ( 116) and the second head connector 118 will be installed.

A fitting groove 212 is formed in the stopper 204 . The fitting groove 212 has an insertion space 212a formed therein so as to have a shape of a constant cross-section in the up-down direction. The shape of the insertion space 212a is the same as that of the fitting protrusion 120 . In a state in which the filter 200 and the filter head 100 are coupled, the fitting protrusion 120 is inserted into the insertion space 212a.

If the filter 200 and the filter head 100 are not the same model, the shape of the cross-section of the fitting protrusion 120 is different from the shape of the cross-section of the insertion space 212a. 100) is not inserted.

The shape of the cross-section of the fitting protrusion 120 and the fitting groove 212 may be variously modified other than those shown in the drawings of the present invention.

A check valve (not shown) for limiting the movement direction of water may be further installed in the first connector 104 to the fourth connector 110 , and the first connector 124 to the third connector 128 . Even if the pressure of the water supplied to the water purifier or the water stored inside the water purifier is reversed due to the check valve, it is possible to prevent the water from flowing back into the filter 200 .
