Description

Shower with built-in filter}

The present invention relates to a shower device with a built-in filter, and more specifically, to a shower device with a filter having a hollow fiber membrane structure applied thereto.

A shower device generally used for showering is connected to a water pipe and a hose to disperse and spray water.

These showers are installed in toilets, sinks, bathrooms, etc. and spray water in a dispersed manner, so the spray area is larger and the water pressure is higher than using a regular hose, so it can be used efficiently.

However, when using a shower, the raw water supplied through the hose contains residual chlorine for disinfection treatment, which functions to block harmful bacteria. However, the residual chlorine dissolved in the raw water causes a unique odor of tap water, causing discomfort to users. In addition, if it reacts with sensitive skin, problems such as skin problems may occur.

Additionally, since raw water supplied through water pipes is stored in a water tank and then supplied to homes or industrial sites, if the inside of the water tank is contaminated, the contaminants are supplied as is.

If raw water containing contaminants is used directly in the human body or used for dish washing or food ingredients, diseases or health problems may occur due to the contaminants.

In order to solve the above problems, Prior Document 1 (Public Patent Publication No. 10-2012-0126486 Showerhead with Smooth Discharge Function and Filter Function) discloses a configuration that can be used by purifying raw water through a filter.

However, the filter disclosed in Prior Document 1 has a cylindrical structure and does not have a sufficient filtration area in the process of filtering raw water, so the filtration efficiency is not good, and the filter is contaminated in a short period of time by filtered foreign substances, causing the problem that it must be replaced.

Referring to FIGS. 1 to 6, the present invention includes a shower head 100 that disperses and sprays water, and a shower body 200 that induces raw water to flow in and move toward the shower head 100. do.

In addition, it is replaceably built into the shower body 200, and can be replaced so that additives effective for the human body can be added to the integrated filter 300 that filters the incoming raw water and the filtered water filtered through the integrated filter 300. It is configured to include a cartridge 400 provided.

Here, the shower head 100 is provided with a spray plate 110 that sprays and discharges water flowing in from the shower body 200.

The shower body 200 includes an upper body 210 provided on the side of the shower head 100 and a lower body 220 provided below the shower head 100.

The upper body 210 includes a cartridge receiving portion 211 in which the cartridge 400 is accommodated, and a cartridge cover 212 that can seal the inside of the upper body 210 while the cartridge 400 is accommodated. It is composed.

At this time, the cartridge cover 212 is provided with an additive confirmation window 212a through which the consumption state of the additive contained in the cartridge 400 can be checked.

And the upper body 210 includes an inlet hole 213 through which filtered water filtered through the integrated filter 300 flows and a head-side discharge hole 214 through which filtered water is discharged toward the shower head 100. do.

Here, the inlet hole 213 is provided with a filtered water check valve 213a that prevents the filtered water from flowing back when it flows into the upper body 210.

The lower body 220 includes a filter receiving portion 221 in which the integrated filter 300 is accommodated in a detachable structure, and a filter coupling groove 222 that couples the integrated filter 300 to an accurate position and fixes it so that it does not flow. This is formed.

The integrated filter 300 includes a hollow fiber membrane filter 310 having a hollow thread shape and a case 320 provided outside the hollow fiber membrane filter 310 to provide a space through which raw water is filtered. .

The hollow fiber membrane filter 310 has a hollow portion 312 formed inside, and is configured to allow raw water to flow in from the outside. As the raw water passes from the outside of the hollow fiber membrane filter 310 to the hollow portion 312, foreign substances or bacteria are removed. etc. are filtered and discharged.

The hollow portion 312 forms a flow path through which filtered raw water can be discharged.

Here, the hollow fiber membrane filter 310 is provided in plural numbers so as to entirely fill the internal space of the case 320.

This hollow fiber membrane filter 310 is finished by a urethane finishing portion 311 at the top of the case 320, so that only the outer surface of the hollow fiber membrane filter 310 is exposed to the inside of the case 320, and the urethane finishing portion ( The hollow portion 312 is opened to the outside of the upper part of 311).

In manufacturing the hollow fiber membrane filter 310, a plurality of hollow fiber membrane filters 310 are inserted into the case 320, and the end of the hollow fiber membrane filter 310 is located on the discharge portion 322 side of the case 320. After being positioned, molten urethane is injected into the discharge portion 322 and cured.

Thereafter, in a state where the urethane is cured, the cured urethane and the end of the hollow fiber membrane filter 310 are cut together to form the same plane as the end of the discharge portion 322 of the case 320, or the hollow fiber membrane filter 310 is formed. It is manufactured so that the end portion and the urethane finish portion 311 form the same surface as the end portion of the discharge portion 322.

As a result, when raw water flows into the case 320, it flows into the outside of the hollow fiber membrane filter 310 due to water pressure and passes through the hollow portion 312, and in this process, foreign substances and bacteria are filtered and discharged.

The filtrated water filtered as described above is discharged through the hollow portion 312 exposed at the top of the urethane finish portion 311 and flows into the upper body 210.

At this time, the hollow fiber membrane filter 310 has a very fine space of 0.1 micrometer through which raw water passes, so that even bacteria such as E. coli can be filtered without passing through.

The case 320 is made entirely of a transparent material so that the contamination state of the hollow fiber membrane filter 310 provided therein can be easily confirmed with the naked eye.

In addition, a plurality of hollow fiber membrane filters 310 are arranged in a thread form inside the case 320 to filter raw water, thereby maximizing the area in which raw water comes into contact with the hollow fiber membrane filter 310, thereby enabling efficient filtration.

The case 320 includes an inlet 321 through which raw water flows in at the bottom, and an outlet 322 at the top through which the inflow raw water passes through the hollow fiber membrane filter 310 and is filtered and discharged. .

In addition, the case 320 has a coupling protrusion 323 that is provided in a shape corresponding to the filter coupling groove 222 and is inserted into and coupled to the filter coupling groove 222 to prevent the integrated filter 300 from flowing. It is provided.

The coupling protrusion 323 and the filter coupling groove 222 are formed in a shape that is wide at the top and narrow at the bottom to enable smooth insertion at the time of initial insertion, and are guided to the correct position as they move toward the bottom and are coupled, making coupling easy. Subsequent flow can be prevented.

In addition, in the case 320, when the integrated filter 300 is coupled to the lower body 220 and the coupling with the upper body 210 is completed, there is a gap between the upper body 210 and the lower body 220 from the outside to the inside. A filter confirmation window 324 is provided to check the contamination status of the hollow fiber membrane filter 310.

As a result, it is possible to easily check the contamination status of the hollow fiber membrane filter 310 with the naked eye at any time during use, even if the shower unit is not removed.

On the other hand, it is provided on the upper part of the case 320, and when the case 320 is coupled with the upper body 210, the upper body side is watertight to maintain the watertightness of the joint area between the upper body 210 and the case 320. An O-ring 325 is provided.

Here, the case 320 and the upper body 210 are coupled by a screw fastening structure.

In one embodiment of the present invention, the description will be based on a state in which a screw thread is formed in the upper part of the case 320 and a screw groove is formed in the lower part of the upper body 210.

The upper body side watertight O-ring 325 is located at the lower end where the thread is formed at the top of the case 320 and is located at the boundary where the upper body 210 and the case 320 are joined.

Accordingly, as the screw connection between the case 320 and the upper body 210 becomes more solid, the body-side watertight O-ring 325 is compressed, thereby increasing the watertight effect.

And, when coupling the case 320 and the lower body 220, a lower body fixing ring 326 is provided at the lower part of the case 320, which can maintain the coupled state without a separate fastening structure.

The lower body fixing ring 326 is provided in the form of a soft ring, and after coupling the case 320 to the lower body 220, the outside of the inlet 321 of the case 320 protrudes downward from the lower body 220. Insert and couple the lower body fixing ring 326.

At this time, the inlet 321 of the case 320 protrudes below the lower body 220, and a hose connection thread 321h to which a hose is connected is provided on the protruding outside.

Accordingly, the case 320 and the lower body 220 can be easily combined and easily connected to the hose using the hose connection thread portion 321h.

At this time, the lower body fixing ring 326 can also serve as a seal to keep the connection area airtight when connected to the water hose.

Meanwhile, the inlet 321 of the case 320 is provided with a disperser 321a that can disperse the incoming raw water and allow it to flow in.

And a regulator (321d) that can control the pressure of raw water flowing in from the water pipe is provided at the lower part of the disperser (321a).

The disperser (321a) has a second flow path (321l) through which raw water flows from the regulator (321d) formed inside, and is coupled to the correct position when coupled to the inside of the inlet 321 along the lower outer circumference. A disperser coupling ring 321b for fixing is provided.

At this time, a disperser coupling step 321i on which the disperser coupling rim 321d is caught and fixed is provided at a portion inside the case 320 where the disperser coupling rim 321d is coupled.

And a plurality of dispersion inflow holes 321c are formed from the top of the disperser 321a toward the outside.

At this time, when the disperser coupling ring rim 321d is coupled to the disperser coupling step 321i, the dispersion inlet hole 321c is coupled to the inside of the case 320 in a protruding state.

Accordingly, when raw water flows into the plurality of distributed inlet holes 321c, raw water can be directly introduced into the case 320.

A raw water distribution plate (321p) is provided at the top of the distribution inlet hole (321c) to prevent the incoming raw water from flowing directly into the hollow fiber membrane filter 310 provided at the top.

The raw water distribution plate (321p) blocks the flow of raw water in the direction in which raw water flows in and guides the raw water to flow into the distribution inlet hole (321c).

The distributed inlet holes 321c are formed in a radial form at regular intervals, so that when raw water flows into the case 320, it is dispersed and guided to flow in, thereby dispersing the water pressure so that the hollow fiber membrane filter 310 is not damaged. There will be.

At this time, the distribution inlet hole 321c is formed by a plurality of pressure distribution ribs 321q provided radially along the circumference of the disperser 321a, and the pressure distribution rib 321q is provided with a plurality of pressure distribution ribs 321q. The raw water flowing in is dispersed and flows into the dispersion inlet hole (321c).

As a result, when raw water flows in, it flows directly into the hollow fiber membrane filter 310, and it is possible to prevent pressure from being directly applied to the hollow fiber membrane filter 310.

Meanwhile, a disperser inflow inclined surface 321j is formed on the lower inner side of the disperser 321a to guide raw water to flow smoothly from the regulator 321d.

The disperser inlet slope 321j is formed in a shape that becomes narrower toward the top of the second flow path 321k, thereby smoothly guiding the flow of incoming raw water.

The regulator (321d) has a first flow path (321k) formed inside it that communicates so that raw water flows in and moves to the disperser (321a), and is directly connected to the hose connected to the water pipe, preventing the backflow of the introduced raw water. A raw water check valve (321e) is provided to prevent this.

And, on the outside of the valve fixing part 321r to which the raw water check valve 321e is fixedly coupled, a water pressure limiting O-ring 321m having elasticity so that its shape can be deformed by the pressure of incoming raw water is provided.

The water pressure limiting O-ring 321m changes its shape depending on the pressure of raw water flowing in through the inlet 321, and has the function of limiting the pressure of raw water flowing into the hollow fiber membrane filter 310.

The water pressure limiting O-ring (321m) changes its shape in a direction that increases its radius due to the pressure of the raw water. In an environment where the raw water pressure is relatively low (for example, the raw water pressure is 3 bar or less), the water pressure limiting O-ring (321m) Since the radius increase is small, the gap (d) between the valve fixing part (321r) and the inner peripheral surface of the regulator (321d) is maintained relatively wide, and the pressure reduction rate of raw water is low.

Conversely, in an environment where raw water pressure is relatively high (for example, raw water pressure exceeds 3 bar), the radius of the water pressure limiting O-ring (321m) increases significantly, so the gap between the valve fixing part (321r) and the inner peripheral surface of the regulator (321d) ( d) becomes relatively narrow and thus the pressure reduction rate of raw water becomes high.

In other words, the water pressure limiting O-ring (321m) is set to have different degrees of shape deformation depending on the pressure of the incoming raw water, thereby increasing the effect of reducing the pressure of raw water, especially in an environment where the raw water pressure is relatively high. This prevents the hollow fiber membrane filter 310 from being damaged.

In addition, on the lower outer side of the regulator (321d), when the regulator (321d) is coupled to the inlet 321 of the case 320, a water tightness is maintained between the regulator (321d) and the inner periphery of the inlet 321 so that it can be coupled. A regulator O-ring (321f) is provided.

At this time, a plurality of pressure control protrusions 321g are formed along the inner periphery of the regulator 321d.

The pressure control protrusions 321g are provided in the form of protrusions extending in the inflow direction of raw water at regular intervals to disperse the raw water flowing in when raw water flows into the inlet 321.

Here, a pressure control slope 321n is formed at the lower part of the pressure control protrusion 321g to guide the flow of raw water smoothly when raw water flows in and to control the pressure.

And, when the hose is connected, a hose coupling guide portion 321o is formed on the lower inner side of the regulator 321d, which can accurately guide the hose coupling position and facilitate coupling.

As a result, when raw water flows into the case 320, the disperser 321a and the regulator 321d distribute the pressure of the raw water and allow it to flow in, thereby minimizing damage to the hollow fiber membrane filter 310 due to water pressure. There will be.

The cartridge 400 has an additive accommodating portion 410 inside which a functional additive can be accommodated.

The additive receiving portion 410 can accommodate and use various ingredients that are effective for the skin and human body, such as vitamins or moisturizers.

In addition, by providing different cartridges 400 for each component, they can be selectively and easily replaced.

This cartridge 400 has a filtered water inlet hole 420 formed in the center through which filtered water flows in from the bottom, and the filtered water that flows in is formed on one side of the lower part of the cartridge 400 through the additive receiving portion 410 and the additive water is discharged. A hole 430 is formed.

Here, the added water discharge hole 430 causes the introduced filtered water to come into contact with the additive contained in the additive receiving portion 410 and to be discharged with the additive added to the filtered water.

Meanwhile, a bypass groove 450 is formed on one side of the cartridge 400 to communicate between the filtered water inlet hole 420 and the cartridge receiving portion 211 so that a portion of the filtered water is discharged without passing through the cartridge 400.

In the bypass groove 450, when all of the filtered water flows into the cartridge 400 and is discharged, the content of additives increases, which can be harmful to the human body, and the consumption of additives also increases, so a certain amount of the cartridge 400 is used. It is equipped so that it can be discharged without passing through.

On the other hand, the cartridge 400 has a bypass groove so that when the bypass groove 450 is not needed depending on the type of additive, all incoming filtered water flows into the cartridge 400 and is discharged through the additive receiving portion 410. (450) may not be formed.

Accordingly, a plurality of bypass grooves 450 are provided with or without forming them depending on the type and use of the additive, so that they can be selectively replaced and used as needed.

The cartridge 400 is coupled from the top of the upper body 210, and is inserted into and coupled to the cartridge receiving portion 211 provided in the upper body 210.

At this time, the upper part of the cartridge 400 and the upper part of the cartridge accommodating part 211 are provided with a cartridge O-ring that can be fixed to maintain watertightness while the cartridge 400 is coupled to the cartridge accommodating part 211. (440) is provided.

Accordingly, the cartridge 400 is inserted and coupled from the upper part of the cartridge receiving portion 211, and the cartridge cover 212 is coupled, so that the added water can be discharged toward the shower head without leaking.

Meanwhile, the cartridge accommodating portion 211 and the cartridge cover 212 are coupled through a rotational fastening structure of protrusions and grooves.

Specifically, a cover engaging protrusion 211a is provided on the outer periphery of the cartridge accommodating portion 211, and the inside of the cartridge cover 212 rotates while the cartridge cover 212 is inserted into the cover engaging protrusion 211a. A rotational coupling groove 212b that can be coupled is formed.

At this time, the rotation coupling groove 212b has a coupling inducing inclined portion 212c that guides the cartridge cover 212 to come into close contact with the cartridge receiving portion 211 when rotationally coupled with the cover coupling protrusion 211a. is formed

And on the inner periphery of the cartridge accommodating part 211, there is a discharge passage forming protrusion that separates the cartridge 400 from the inner periphery by a certain distance and forms a passage through which the additive water discharged from the cartridge 400 is discharged toward the shower head 100. (211b) is provided.

As a result, after the cartridge 400 is coupled to the cartridge accommodating portion 211, the cartridge cover 212 is inserted and rotated to allow the cartridge 400 to be coupled in close contact with the cartridge cover 212.

As described above, the cartridge O-ring 440 can keep the inside of the cartridge accommodating part watertight as the cartridge cover 212 is in close contact with the cartridge accommodating part 211 and is rotationally coupled.

Figure 7 is an operating state diagram showing a state in which raw water is filtered in a shower head with a built-in filter according to an embodiment of the present invention.

Referring to FIG. 7, raw water flows into the inlet 321 of the case 320, sequentially passes through the regulator 321d and the disperser 321a during the flow, and enters the case 320 with the water pressure adjusted. flows inside.

At this time, the raw water first passes through the regulator 321d, and as the raw water flows into the first flow path 321k formed inside the regulator 321d, the pressure control protrusion ( 321g), the water pressure is distributed and flows in evenly.

The water pressure is distributed, and the inflowed raw water passes through the second flow path 321l formed in the disperser 321a and is dispersed outward from the inlet 321 by the dispersion inlet hole 321c of the disperser 321a. (320) flows inside.

At this time, a raw water dispersion plate 321p is formed on the upper part of the disperser 321a to guide the flow of raw water from the inflow direction toward the dispersion inlet hole 321c.

Here, the raw water check valve 321e is soft and capable of being deformed and restored, and is deformed by the pressure of raw water flowing in, allowing raw water to flow in, and when the pressure of raw water flowing in is released, it is restored to its original form and the raw water flowing in is restored to its original form. Blocks backflow.

As described above, the raw water flowing into the case 320 passes through the hollow portion 312 from the outside of the hollow fiber membrane filter 310, and foreign substances and bacteria are filtered out, and the filtrated water filtered by the hollow fiber membrane filter 310 is It is discharged to the discharge part 322 and flows into the upper body 210.

Figure 8 is an operational state diagram showing the state in which filtered water passes through a cartridge in a shower head with a built-in filter according to an embodiment of the present invention.

Referring to FIG. 8, the filtered water filtered and discharged from the integrated filter 300 flows into the upper body 210 through the inlet hole 213 of the upper body 210.

The filtered water flowing in through the inlet hole 213 is caused by the cartridge 400 accommodated in the upper body 210 being in communication with the inlet hole 213, so that the filtrated water flows through the inlet hole 213 and is in contact with the cartridge 400. The filtered water flows into the inlet hole 420 formed in the lower center.

At this time, a portion of the introduced filtered water is discharged directly through the bypass groove 450 without passing through the cartridge 400.

As described above, the filtered water flowing into the cartridge 400 comes into contact with the additive contained in the cartridge 400 and the additive is added, and the additive water is released through the additive water discharge hole formed on one side of the lower part of the cartridge 400. It is discharged through (430).

The added water discharged through the added water discharge hole 430 moves into the space formed by the discharge passage forming protrusion 211b between the inner periphery of the cartridge receiving portion 211 and the cartridge 400, and the cartridge receiving portion 211 It is discharged to the shower head 100 through the head side discharge hole 214 in communication with (211).

In the above process, the added water that passed through the cartridge 400 and the filtrated water that did not pass through the cartridge 400 are mixed at an appropriate concentration in the flow path between the cartridge 400 and the inner peripheral space of the cartridge receiving portion 211.

At this time, when the inflow of raw water from the outside is blocked inside the cartridge 400, the filtered water remains inside the cartridge 400 and comes into contact with the additive for a long time, allowing the additive to be efficiently added to the filtered water.

Then, when the inflow of raw water begins again, the added water remaining in the cartridge 400 is discharged to the shower head 100 by water pressure.

Meanwhile, the filtered water flowing into the cartridge 400 does not flow back even if the water pressure flowing in is released by the filtered water check valve 213a provided in the inlet hole 213 of the upper body 210 and the cartridge 400 and the cartridge accommodation. It can remain inside the unit 211.

The present invention made as described above can be used by filtering foreign substances and bacteria from raw water flowing in from a water pipe when using a shower, and at the same time, ingredients effective for the human body can be added to the filtered water.

In addition, filtration efficiency can be increased by maximizing the contact area between the hollow fiber membrane filter and raw water during the filtration process, and by dispersing the water pressure of the raw water flowing into the hollow fiber membrane filter to allow it to flow in, it can be used while minimizing damage to the hollow fiber membrane filter. do.
