Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

According to an embodiment of the present invention, a water purifier includes: a pipe having a passage for allowing water to flow or for allowing water to accumulate; the light source module comprises a substrate and a light source for emitting sterilizing ultraviolet rays. The light source module is fixed to the outer wall of the pipe and irradiates the inside of the pipe with sterilizing ultraviolet rays.

The piping may further include: an opening part in a penetrating form; a mounting portion formed so as to surround the periphery of the opening portion; and a fastening portion formed to protrude from the outer wall.

The base plate may further include a fastening groove in a penetrating manner. The fastening member is fastened to the fastening portion through the fastening groove.

The pipe may further include a locking portion protruding from the outer wall and having one end bent.

The substrate may further include a fixing hole in a penetrating manner. The locking portion passes through the fixing hole, and a part of the substrate is inserted between the locking portion and the outer wall.

The water purifier may further include: a sealing member mounted on the mounting portion; and a transparent window that closes the opening and transmits sterilization ultraviolet rays.

The water purifier may further include a fixing member to which the light source module is mounted and fixed to the pipe.

According to an embodiment, the fixing member further includes: a through hole having a through shape; a substrate mounting portion for mounting the substrate so that the light source is positioned in the through hole; and a fastening groove including a fastening hole having a penetrating shape. The fastening portion of the outer wall is fastened to the fastening groove through the fastening hole of the fixing member.

The fastening portion may further include a protrusion formed in a protruding structure at one side.

The fixing member may further include a locking groove as a groove having a structure corresponding to the protruding portion in the inner wall of the through groove.

When the fastening portion moves along the fastening groove while passing through the fastening hole, the protrusion is inserted into the locking groove to fix the fixing member to the pipe.

The area of the piping through which the sterilizing ultraviolet rays pass may be a transparent area formed of a light-transmitting material.

According to another embodiment, the fixing member is attached with the light source module and at least a part of the fixing member contacts a foreign currency of the piping to be fixed to the piping. The light source module attached to the fixing member irradiates sterilizing ultraviolet rays into the pipe through the transparent region.

For example, the first fastening portion may include a groove that opens in a forward direction of the substrate mounting portion, which is a direction in which the pipe is located.

At this time, the second fastening portion is formed such that one end is attached to the outer wall of the pipe and the other end protrudes in the forward direction of the pipe opposite to the direction in which the sterilizing ultraviolet rays are irradiated. And, the other end of the second fastening portion is inserted into the groove of the first fastening portion to fasten the first fastening portion and the second fastening portion to each other.

For example, the first fastening portion may be formed such that one end is connected to the substrate mounting portion and the other end protrudes in a forward direction of the substrate mounting portion, which is a direction in which the piping is located.

The second fastening portion includes a through hole. And, the other end of the first fastening portion is inserted into the through hole of the second fastening portion, thereby fastening the first fastening portion and the second fastening portion to each other.

And, the other end of the first fastening part may include a bent structure. At this time, the other end of the first fastening portion is inserted into the through hole of the second fastening portion, thereby fastening the bent portion of the first fastening portion to the through hole of the second fastening portion.

The second fastening portion includes a groove that opens in a forward direction of the pipe in a direction opposite to a direction in which the sterilizing ultraviolet light is irradiated. And, the other end of the first fastening portion is inserted into the groove of the second fastening portion, thereby fastening the first fastening portion and the second fastening portion to each other.

According to an embodiment of the present invention, the water purifier 100 includes a pipe 110, a light source module 130, and a fixing member 160. The water purifier 100 according to the present embodiment fixes the light source module 130 to the pipe 110 by the fixing member 160, and sterilizes water flowing through the pipe 110 or accumulated in the pipe 110. In the description of the present embodiment, a description of general components of a known water purifier such as a water storage unit and a water purifying device will be omitted.

The pipe 110 is a passage through which water flows for discharge to the outside. If a drain (not shown) of the water purifier 100 is opened, water flows from a water storage part (not shown) along the pipe 110 and is discharged outward through the drain. If the drain port is closed, water that cannot be discharged to the outside due to the drain port being blocked is accumulated in the pipe 110. If water does not flow and accumulates in a space, it may be contaminated with contaminants such as bacteria or viruses.

An opening 111 is formed in the pipe 110. The sterilizing ultraviolet rays of the light source module 130 are irradiated into the pipe 110 through the opening 111. The size of the opening 111 may be determined in consideration of the irradiation angle of the light source module 130 or the emission range of the sterilizing ultraviolet rays. The sterilizing uv light emitting range of the light source module 130 may be different depending on the number of the light sources 132 or the arrangement structure of the plurality of light sources 132.

The pipe 110 has a fastening portion 150 formed on the outside thereof. The fastening portion 150 is coupled to the fixing member 160, whereby the fixing member 160 is fixed to the pipe 110. As shown, the fastening part 150 is formed to have a long length in one direction. Further, a protrusion 151 is formed on a side surface of one end of the fastening portion 150. The protruding portion 151 is formed to correspond to the locking groove 167 of the fixing member 160. Further, the fastening portion 150 is a curved surface having a curvature on a side surface.

An outer wall of the pipe 110 is formed with an installation portion 170 protruding outward. The mounting portion 170 is constituted by a first protruding portion 171 and a second protruding portion 172. The first protrusion 171 and the second protrusion 172 are formed to surround the periphery of the opening 111. The first protrusion 171 and the second protrusion 172 are spaced apart from each other, and the second protrusion 172 is located in an inner region of the first protrusion 171. Referring to fig. 1, the second protruding portion 172 has a structure extending in an outer direction from the opening inner wall 112. Here, the opening inner wall 112 is an inner wall of the pipe 110 constituting the opening 111. And, the height of the second protrusion 172 is smaller than that of the first protrusion 171. Here, the height of the first protrusion 171 and the second protrusion 172 is a length protruding outward from the outer wall of the pipe 110.

A sealing member insertion groove into which the sealing member 180 is inserted may be formed between the first protrusion 171 and the second protrusion 172. The sealing member 180 is made of a material having elasticity such as rubber. The thickness of the sealing member 180 is greater than the height of the second protrusion 172. Here, the thickness of the sealing member 180 refers to a distance between an upper surface in contact with the outer wall of the pipe 110 and a lower surface in contact with the transparent window 120. Accordingly, the sealing member 180 protrudes from the second protrusion 172 when inserted into the sealing member insertion groove. The sealing member 180 protrudes beyond the second protruding portion 172 so that the transparent window 120 can be brought into close contact with the second protruding portion 172 when the fixing member 160 is attached to the pipe 110. Since the transparent window 120 and the second protruding portion 172 are in close contact with each other, the opening 111 of the pipe 110 and the transparent window 120 can be sealed more firmly by the pressure when the fixing member 160 is attached to the pipe 110.

Further, since the sealing member 180 is formed of an elastic material, the pressure applied to the transparent window 120 can be buffered when the pipe 110 is attached to the fixing member 160. Accordingly, the sealing member 180 can prevent the transparent window 120 from being broken due to pressure applied to the transparent window 120 when the fixing member 160 is mounted to the pipe 110.

The light source module 130 includes a light source 132 and a substrate 131. The light source 132 is a light emitting diode chip that emits ultraviolet rays of a wavelength band having a sterilizing effect. That is, the light source module 130 emits sterilizing ultraviolet rays. For example, the bactericidal ultraviolet is ultraviolet in the wavelength band of 300nm to 290 nm. The substrate 131 is a substrate on which a circuit for electrically controlling the light source 132 is formed.

The light source module 130 is attached to the fixing member 160, and irradiates ultraviolet rays into the inside of the pipe 110 through the through hole 164 of the fixing member 160, the transparent window 120, and the opening 111 of the pipe 110.

The fixing member 160 is fixed to the pipe 110. If the fixing member 160 is fixed to the pipe 110, the light source module 130 attached to the fixing member 160 can radiate sterilizing ultraviolet rays into the pipe 110 through the opening 111 of the pipe 110.

According to the present embodiment, the fixing member 160 includes a through hole 164, a substrate mounting portion 161, a fastening groove 165, a transparent window pressing portion 168, and a protruding portion insertion groove 169.

The through hole 164 is a hole penetrating the upper and lower surfaces of the fixing member 160. The through hole 164 has the light source 132 of the light source module 130 attached to the fixing member 160, and is a passage through which the sterilizing ultraviolet rays pass.

The substrate mounting portion 161 is formed on the lower surface of the fixing member 160. The substrate mounting portion 161 protrudes in a lower direction on the lower surface of the substrate 131, and is formed in a structure in which the protruding end is bent. Therefore, the substrate mounting portion 161 will have a groove into which the side surface of the substrate 131 can be inserted. If both side surfaces of the substrate 131 are inserted into the substrate mounting part 161 of the above-described form, the light source module 130 is mounted to the fixing member 160.

The fixing member 160 has a transparent window pressing portion 168 and a protruding portion insertion groove 169 formed on an upper surface thereof.

The transparent window pressing portion 168 extends from the inner wall of the fixing member 160 constituting the through hole 164 and protrudes in the upper direction. At this time, the upper surface of the transparent window pressing portion 168 is lower in height than the upper surface of the fixing member 160 around the outer circumference of the protruding portion insertion groove 169.

The transparent window pressurizing section 168 pressurizes the transparent window 120 when the fixing member 160 is attached to the pipe 110. The transparent window 120 is pressed against the sealing member 180 by the pressing force from the transparent window pressing portion 168, and thereby the sealing between the pipe 110 and the fixing member 160 is made stronger.

The length of the inner wall of the fixing member 160 constituting the transparent window pressing portion 168 and the through hole 164 is greater than the thickness of the light source 132. Here, the length of the inner wall of the fixing member 160 refers to the distance from the upper surface to the lower surface of the fixing member 160. The thickness of the light source 132 is a distance from the lower surface to the upper surface of the substrate 131. Accordingly, when the light source module 130 is mounted to the fixing member 160, the light source 132 is located at the through hole 164 and spaced apart from the transparent window 120. Therefore, breakage caused by the light source 132 and the transparent window 120 being closely attached to each other or colliding with each other can be prevented.

The protruding portion insertion groove 169 is formed along the periphery of the transparent window pressing portion 168. The protruding portion insertion groove 169 is formed in a groove shape recessed from the transparent window pressing portion 168. When the fixing member 160 is attached to the pipe 110, the first protrusion 171 of the pipe 110 is inserted into the protrusion insertion groove 169. Therefore, when the fixing member 160 is attached to the pipe 110, the outer wall of the pipe 110 and the upper surface of the fixing member 160 can be closely attached.

The fixing member 160 is formed at a lower surface thereof with a fastening groove 165. The fastening groove 165 is configured to fasten to the fastening portion 150 of the pipe 110. The fastening groove 165 is located outside the through hole 164 and the protruding portion insertion groove 169.

A fastening portion insertion groove 166 into which the fastening portion 150 of the pipe 110 can be inserted is formed in a part of the fastening groove 165. The fastening portion insertion groove 166 is a groove penetrating the fixing member 160. The inner sidewall of the fixing member 160 constituting the fastening portion insertion groove 166 has a curvature corresponding to the fastening portion 150.

A locking groove 167 is formed in an inner wall of the fixing member 160 constituting the fastening groove 165. The locking groove 167 is a groove structure corresponding to the protrusion 151 of the fastening portion 150 of the pipe 110. If the locking groove 167 is inserted into the protrusion 151 of the fastening portion 150, the fixing member 160 is attached to the pipe 110.

According to the present embodiment, when the fastening portion 150 of the pipe 110 is inserted into the fastening portion insertion groove 166 of the fixing member 160 and then the fixing member 160 is rotated in one direction, the protrusion 151 of the fastening portion 150 is inserted into the locking groove 167 of the fixing member 160. The fixing member 160 is attached to the pipe 110 in this way.

The water purifier 100 may further include a guide 190. Here, the guide 190 may be formed to protrude at a lower surface of the fixing member 160. The guide part 190 guides the position where the substrate 131 of the light source module 130 is mounted to the fixing member 160. For example, the guide portion 190 may be formed to be closely attached to a side surface different from the side surface of the substrate 131 inserted into the substrate mounting portion 161. Such a guide portion 190 can prevent the substrate 131 from moving in a direction different from the direction in which the substrate mounting portion 161 is arranged when mounted on the fixing member 160.

Also, although not shown in the drawings, in order to more firmly fix the light source module 130 to the fixing member 160, the light source module 130 may be further fixed to the fixing member 160 by using screws.

The light source module 130 may be located at an outer wall of a pipe disposed between the water storage part and the water discharge port. Or in the case where the water purifier 100 does not include the water storage part, the light source module 130 is positioned between the inlet into which the raw water is put and the water discharge port, and is closer to the water discharge port therebetween. Therefore, the water purifier 100 may sterilize water before the water is discharged to the outside, rather than storing the water in the water storage part after sterilizing the water. In addition, in the case where purified water is stored in the water storage part, the water purifier 100 may sterilize the water again before the water is discharged to the outside through the discharge port. As such, since the water purifier 100 according to the present embodiment performs sterilization before water is discharged, a water purifying function is improved. If the light source module 130 is fixed to a pipe near the drain port, sterilization can be performed before the water is discharged, thereby improving the water purifying efficiency of the water purifier 100. Further, if the light source module 130 is fixed to the upper portion of the bent pipe 110, the inside of the pipe 110 extending in the lower direction may be irradiated with sterilizing ultraviolet rays. That is, since the irradiation range and irradiation area of the sterilizing ultraviolet rays become large, the water purifier 100 can sterilize a large amount of water at a time.

Fig. 5 shows a side sectional view of a water purifier 200 according to a second embodiment. In describing the water purifier 200 according to the second embodiment, a description of the same configuration as that of the water purifier (100 of fig. 1 to 4) according to the first embodiment will be omitted. The omitted explanation will be referred to the explanation of fig. 1 to 4 as the first embodiment.

Referring to fig. 5, a water purifier 200 according to the second embodiment is different from the water purifier (100 of fig. 1 to 4) according to the first embodiment in the structure of an inner wall (112 of fig. 3) of an opening portion.

At least a part of the opening inner wall 212 is formed to have an inclination. Referring to fig. 5, the opening inner walls 212 facing each other have slopes gradually away from each other from the middle toward the inside of the pipe 110. Accordingly, the opening 111 has a structure in which the diameter gradually increases from the middle toward the inside of the pipe 110.

According to the present embodiment, the inclination of the opening inner wall 212 may be changed according to the illumination angle of the light source module 130. That is, since the opening inner wall 212 is formed to have an inclination, the sterilizing ultraviolet light emitted from the light source module 130 can be irradiated into the pipe 110 without hitting the opening inner wall 212 as much as possible.

If the sterilizing ultraviolet rays collide with the inner wall when passing through the opening, not all the sterilizing ultraviolet rays that collide are reflected toward the inside of the pipe 110. The part of the sterilizing ultraviolet rays impinging on the inner wall of the opening portion can be absorbed by the inner wall. Further, another part of the sterilizing ultraviolet light is reflected on the inner wall of the opening, and can be re-absorbed by the light source 132 toward a place other than the inside of the pipe 110 or toward the light source module 130.

However, the water purifier 200 according to the present embodiment can reduce the phenomenon that sterilizing ultraviolet rays collide with the opening portion inner wall 212 by having the opening portion inner wall 212 inclined.

Further, since the opening inner walls 212 facing each other in the water purifier 200 are spaced farther from each other toward the inside of the pipe 110, the sterilizing ultraviolet light can be reflected toward the inside of the pipe 110 when colliding with the opening inner walls 212 having an inclination.

Therefore, the water purifier 200 according to the present embodiment can reduce the disappearance of the sterilizing ultraviolet rays toward the inside of the pipe 110 by having the inclined opening inner wall 212, thereby improving the sterilizing efficiency and the purifying efficiency of water.

Although the case where the opening inner wall 212 has an inclination from the intermediate portion is shown and described in the present embodiment, the structure of the opening inner wall 212 is not limited thereto. For example, the opening inner wall 212 may have an inclined structure from the entrance of the opening 111. As described above, the portion having the inclination in the opening inner wall 212 and the inclination angle may be changed in consideration of the portion of the light source module 130 that emits the sterilizing ultraviolet light, the irradiation angle, the distance between the light source module 130 and the opening 111, and the like.

Fig. 6 is an exploded view of a part of the components constituting the water purifier according to the third embodiment, fig. 7 is a plan view of the combination of the components of fig. 6, and fig. 8 is a side sectional view of the water purifier.

The description of the water purifier 300 of the third embodiment will be omitted when describing the water purifier 300 of the first embodiment.

According to the third embodiment, the water purifier 300 includes the piping 110, the light source module 330, and the fastening member 340. For example, the fastening member 340 is a screw. That is, in the water purifier 300 of the present embodiment, the light source module 330 is fixed to the pipe 110 by screw fastening.

An outer wall of the pipe 110 is formed with a mounting portion 370 protruding outward. The first sealing member 381, the second sealing member 382, and the transparent window 120 are attached to the attachment portion 370.

The first seal member 381 and the second seal member 382 have a structure in which a through hole having a size at least larger than the opening 111 of the pipe 110 is formed.

The transparent window 120 is located between the first sealing member 381 and the second sealing member 382.

The sum of the thicknesses of the first sealing member 381, the second sealing member 382, and the transparent window 120 is greater than the height of the mounting portion 370. Therefore, when the light source module 330 is fixed to the pipe 110, the substrate 331 is in close contact with the second sealing member 382. At this time, when the light source module 330 is fastened to the pipe 110, both the first sealing member 381 and the second sealing member 382 are pressurized by the substrate 331, so that the opening 111 of the pipe 110 can be firmly sealed.

When the second sealing member 382 is pressed by the substrate 331, the thickness thereof needs to be thicker than that of the light source 332. The second sealing member 382 needs to be thicker than the light source 332 when compressed, so that breakage of the light source 332 and the transparent window 120 due to collision with each other can be prevented when the light source module 330 is fixed to the pipe 110.

Further, a fastening portion 311 having a protruding structure is formed on the outer wall of the pipe 110. The fastening portion 311 has a fastening groove 312 into which one end of the fastening member 340 can be inserted. The upper surface of the fastening portion 311 may be disposed lower than one side of the second sealing member 382 mounted at the mounting portion 370. Here, one surface of the second sealing member 382 is a surface that is in close contact with the substrate 331. Therefore, when the light source module 330 is fixed to the pipe 110 by the fastening member 340, the substrate 331 presses the second sealing member 382. As a result, the first sealing member 381, the transparent window 120, and the second sealing member 382 are closely adhered by a strong force, so that the opening 111 of the pipe 110 can be firmly sealed.

Further, an engaging portion 313 whose end is curved like a hook is formed on the outer wall of the pipe 110. The locking portion 313 may be considered to include a groove into which a part of the substrate 331 can be inserted.

In an embodiment of the present invention, the substrate 331 of the light source module 330 is a metal substrate. Since the substrate 331 is formed of a metal material, heat dissipation efficiency is improved. Further, since the substrate 331 is made of metal, it is strong. Therefore, when the substrate 331 is fixed to the pipe 110, the substrate 331 can be prevented from being bent by the force with which the fastening member 340 and the fastening groove 312 of the pipe 110 are fastened.

A fastening hole 333 through which a part of the fastening member 340 passes is formed at a part of the substrate 331 of the light source module 330. A fixing hole 334 through which the locking portion 313 of the pipe 110 passes is formed in the other portion of the substrate 331.

The locking portion 313 of the pipe 110 is locked to the substrate 331 through the fixing hole 334 of the substrate 331. At this time, in the base plate 331, the inner surface constituting the fixing hole 334 is inserted between the locking portion 313 and the outer wall of the pipe 110. At this time, the lower surface of the substrate 331 is in contact with the lower surface of the curved portion of the locking portion 313. The locking portion 313 does not separate the substrate 331 from the outer wall of the pipe 110 by a predetermined distance or more. The locking portion 313 prevents the substrate 331 fixed to the pipe 110 from moving and the light source 332 from being out of the predetermined position.

According to the present embodiment, the distance from the outer wall of the pipe 110 to the lower surface of one end of the locking portion 313 is the same as the sum of the height from the outer wall of the pipe 110 to the upper surface of the fastening portion 311 and the thickness of the substrate 331. Here, the lower surface of one end of the locking portion 313 is a portion that contacts the lower surface of the substrate 331. Therefore, if the substrate 331 is fixed to the piping 110 by the fastening member 340, the substrate 331 can be maintained horizontal.

If the locking portion 313 is not provided, the force by which the fastening member 340 penetrates the substrate 331 to be coupled to the fastening hole 333 may separate a portion of the substrate 331 that is not fixed to the pipe 110 from the outer wall of the substrate 331. If a portion of the base plate 331 is spaced apart from the outer wall, the force with which the portion pressurizes the first sealing member 381, the transparent window 120, and the second sealing member 382 becomes weak, and thus water leakage occurs.

However, the water purifier 300 of the present embodiment may be fixed to the pipe 110 in a state where the substrate 331 is maintained horizontal by the fastening hole 333 and the locking portion 313 of the pipe 110. Therefore, when substrate 331 is fixed to pipe 110, second seal member 382 is applied with a uniform force as a whole, so that water leakage due to uneven pressurization can be prevented.

If the substrate 331 fixed to the pipe 110 is not kept horizontal, the irradiation angle of the light source 332 is inclined. In this case, only a part of the sterilizing uv rays of the light source 332 may pass through the pipe 110, and another part may be irradiated to the outer wall of the pipe 110 or the like.

In the water purifier 300 of the present embodiment, since the substrate 331 is fixed to the pipe 110 while being maintained horizontal, all of the sterilizing ultraviolet rays of the light source 332 pass through the opening 111 of the pipe 110, and thus the sterilizing efficiency for water is improved.

According to the present embodiment, the fastening holes 333 and the fixing holes 334 of the substrate 331 are formed at positions corresponding to the fastening portions 311 and the locking portions 313 of the pipe 110. For example, the fastening portion 311 and the locking portion 313 of the pipe 110 are located on the center line of the opening 111 of the pipe 110. Also, the fastening hole 333 and the fixing hole 334 of the substrate 331 are located on the center line of the substrate 331.

The light source 332 of the light source module 330 is disposed on the upper surface of the substrate 331. Therefore, if the light source module 330 is fixed to the pipe 110, the light source 332 is disposed inside the second sealing member 382.

The water purifier 300 according to the present embodiment may further include a guide 314 and a guide groove 335.

The guide 314 is formed in the pipe 110, and the guide groove 335 is formed in the substrate 331.

The guide portion 314 is formed outside the mounting portion 370 where the fastening portion 311 and the locking portion 313 are not formed. Therefore, the guide groove 335 is also formed to be recessed in the side surface where the fastening hole 333 and the fixing hole 334 are not formed. If the light source module 330 is mounted to the pipe 110, a part of the guide 314 is inserted into the guide groove 335 of the substrate 331. Therefore, if the light source module 330 is attached to the pipe 110 through the guide portion 314 and the guide groove 335, the center of the light source 332 and the center of the opening 111 of the pipe 110 can be aligned.

The fixing member 460 mounted to the pipe 110 in the water purifier 400 according to the fourth embodiment includes a first fastening part 463, a second fastening part 465, and a substrate mounting part 461.

In the present embodiment, the fixing member 460 and the light source module 130 are disposed in the pipe 110 connected to the drain port 450 that discharges water.

The pipe 110 includes a transparent region having an outer wall made of a light-transmitting material. In the embodiment of the present invention, the entire outer wall of the pipe 110 is formed of a light-transmitting material.

Accordingly, the sterilizing ultraviolet rays of the light source module 130 can be irradiated into the pipe 110 through the entire outer wall of the pipe 110.

For example, the pipe 110 is made of a material having high ultraviolet transmittance such as glass, quartz, or PMMA.

Since the entire outer wall of the pipe 110 is made of a light-transmitting material, the light source module 130 can emit sterilizing ultraviolet rays into the pipe 110 at any position.

The light source module 130 is mounted on the substrate mounting portion 461. The substrate mounting portion 461 may be formed to surround the entire outer side surface of the light source module 130, or may be formed to surround a part of the outer side surface of the light source module 130.

The first fastening portions 463 are formed on both side surfaces of the substrate mounting portion 461, and are formed to protrude in the front direction of the substrate mounting portion 461. Here, the forward direction of the substrate mounting portion 461 is the direction in which the pipe 110 is arranged. One end of the first fastening portion 463 is connected to a side surface of the substrate mounting portion 461, and the other end of the first fastening portion 463 is formed in a curved structure.

The second fastening portion 465 is attached to the outer wall of the pipe 110, and a through hole 466 is formed. For example, the second fastening portion 465 may be attached to the outer wall of the pipe 110 by an adhesive substance. Or the second fastening portion 465 may be fixed to the outer wall of the pipe 110 by any known attaching method. The second fastening portions 465 are formed at positions corresponding to the first fastening portions 463, respectively.

In a state where the first fastening portion 463 is biased, the other end of the first fastening portion 463 is inserted into the through hole of the second fastening portion 465. If the applied force is removed in this state, the bent other end of the first fastening part 463 is caught in the second fastening part 465 to fasten the first fastening part 463 and the second fastening part 465 to each other. The light source module 130 is fixed to the outside of the pipe 110 by such fastening.

Although a pair of the first fastening part 463 and the second fastening part 465 are shown in the drawing, the number and forming positions of the first fastening part 463 and the second fastening part 465 may be changed according to the selection of a person skilled in the art.

According to an embodiment of the present invention, the light source module 130 may be disposed outside the piping 110 by means of the fixing member 460 so as to radiate sterilizing ultraviolet rays to the inside. Therefore, the light source module can be prevented from being damaged by water or moisture of the piping 110. In addition, when a failure occurs in the light source module 130, the substrate mounting portion 461 of the fixing member 460 can be separated from the pipe 110, so that the light source module 130 can be easily repaired or replaced.

Also, the first fastening part 463 of the fixing member 460 may be detachable from the fixing member 460. For example, since Velcro (Velcro) is formed on the outer wall of the fixing member 460 and the first fastening portion 463, the first fastening portion 463 can be attached to and detached from the fixing member 460. Or the outer wall of the fixing member 460 and the first fastening part 463 include a structure having magnetism or magnetic force so that the first fastening part 463 can be detached from the fixing member 460. Furthermore, the first fastening portion 463 may be attached to and detached from the fixing member 460 by another kind of adhesive or adhesive medium.

According to an embodiment of the present invention, the sterilizing ultraviolet rays of the light source module 130 are irradiated to the water accumulated inside the piping 110 through the outer wall of the piping 110. Therefore, the water accumulated in the pipe 110 is sterilized by the sterilizing ultraviolet rays, and thus can be kept clean at all times. That is, although the purified water may be contaminated when flowing along the pipe 110 or accumulating in the pipe 110, the purified water is sterilized again in the pipe 110, and thus the water purifying effect of the water purifier is improved.

In this embodiment, a case where the entire outer wall of the pipe 110 is made of a light-transmitting material will be described. However, the entire outer wall of the pipe 110 is not necessarily formed of a light-transmitting material. A part of the outer wall of the pipe 110 may be formed as a transparent region made of a light-transmitting material. At this time, the fixing member 460 may fix the light source module 130 at a position where the sterilizing ultraviolet rays can be irradiated into the pipe 110 through the transparent region.

In the water purifier 500 according to the fifth embodiment, the fixing member 560 includes a first fastening part 563, a second fastening part 566, and a substrate mounting part 561.

The first fastening portion 563 is formed at the substrate mounting portion 561. According to the fifth embodiment, the first fastening portion 563 has a structure including the groove 564 that is opened toward the front direction of the substrate mounting portion 561. The groove 564 of the first fastening portion 563 may have a structure corresponding to the other end of the second fastening portion 565. In this case, if the other end of the second fastening part 565 is inserted into the groove 564 of the first fastening part 563, the first fastening part 563 and the second fastening part 565 can be firmly fastened. However, the groove 564 of the first fastening portion 563 and the other end of the second fastening portion 565 do not necessarily have corresponding structures. The fixing member 560 may be of any structure as long as it can be fixed to the pipe 110 when the groove 564 of the first fastening portion 563 and the other end of the second fastening portion 565 are coupled to each other. In fig. 10, a first fastening portion 563 is formed at the side surface outer wall of the substrate mounting portion 561. However, the position where the first fastening part 563 of the fifth embodiment is formed is not limited thereto, and may be formed at any position as long as it can be coupled with the second fastening part 565. For example, the first fastening part 563 may be a groove formed between the inner wall and the outer wall of the substrate mounting part 561 without an additional structure.

The second fastening portion 565 is fixed to the outer wall of the pipe 110. The second fastening portion 565 is formed such that one end is attached to the outer wall of the pipe 110 and the other end protrudes in the forward direction of the pipe 110.

The fixing member 560 is fixed to the pipe 110 by inserting the other end of the second fastening portion 565 into the first fastening portion 563.

In the fifth embodiment, the fixing member 560 may be fixed to the pipe 110 by a pair of the first fastening portions 563 and the second fastening portions 565. If the fixing member 560 includes two pairs of the first fastening parts 563 and the second fastening parts 565, the fixing member 560 can be more firmly fixed to the pipe 110.

In the water purifier 600 according to the sixth embodiment, the fixing member 660 includes a first fastening part 663, a second fastening part 665, and a substrate mounting part 661.

The first fastening portion 663 is formed on a side surface of the substrate mounting portion 661. The first fastening portion 663 is formed such that one end is connected to a side surface of the substrate mounting portion 661 and the other end protrudes in the front direction of the substrate mounting portion 661.

The second fastening portion 665 is attached to the outer wall of the pipe 110. The second fastening portion 665 includes a groove 666 that opens in the forward direction of the pipe 110.

The fixing member 660 is fixed to the pipe 110 by inserting the first fastening portion 663 into the other end of the second fastening portion 665.

A part of the fixing members 160, 460, 560, 660 according to the first to sixth embodiments of the present invention is attached to the outer wall of the piping 110. Therefore, the fixing members 160, 460, 560, 660 can be fixed without falling off the pipe 110 even under an external impact.

Fig. 12 schematically shows a structure of a fixing member 760 mounted to a pipe 110 in a water purifier 700 according to a seventh embodiment in plan view.

According to the seventh embodiment, the fixing member 760 includes a first support portion 763, a second support portion 765, and a substrate mounting portion 761.

The first support portion 763 is formed at one side of the substrate mounting portion 761, and the second support portion 765 is formed at the other side of the substrate mounting portion 761. The first support portion 763 and the second support portion 765 are formed of metal or plastic having an elastic force.

One ends of the first support portion 763 and the second support portion 765 are formed to be connected to the substrate mounting portion 761, and the other ends of the first support portion 763 and the second support portion 765 are formed to protrude in the front direction of the substrate mounting portion 761. The other ends of the protruding first support portion 763 and second support portion 765 are in contact with the outer wall of the pipe 110.

The distance between the first support portion 763 and the second support portion 765 is smaller than the diameter of the portion of the pipe 110 to which the fixing member 760 is attached. The pipe 110 is positioned between the first support portion 763 and the second support portion 765 in a state where the first support portion 763 and the second support portion 765 are opened outward by the application of force. If the applied force is removed in this state, the first support portion 763 and the second support portion 765 pressurize the outer wall of the piping 110 due to the elastic force, thereby fixing the fixing member 760 to the piping 110.

In the case where the fixing member 760 includes the first support portion 763 and the second support portion 765 having elastic force, the fixing member 760 may be fixed to the pipe 110 even if an additional constituent portion for fastening the pipe 110 is not provided, unlike the previous embodiment.

Fig. 13 schematically shows a structure of a fixing member 860 attached to a pipe 110 in a water purifier 800 according to an eighth embodiment in plan view.

According to the eighth embodiment, the fixing member 860 includes a first support portion 863, a second support portion 865, a substrate mounting portion 861, and a buffer member 870.

Buffer member 870 is formed on a surface of first support 863 and second support 865 facing each other. The buffer member 870 may be formed of any material as long as it is made of a material such as rubber or sponge that can buffer a force applied from the outside.

Such a cushioning member 870 functions to cushion the pressure received by the pipe 110 from the first support portion 863 and the second support portion 865. Accordingly, the pipe 110 can be prevented from being damaged by the pressurization of the first support portion 863 and the second support portion 865.

Fig. 14 schematically shows a structure of a fixing member 960 attached to a pipe 110 in a water purifier 900 according to a ninth embodiment in plan view.

According to the ninth embodiment, the fixing member 960 includes a first support portion 963, a second support portion 965, a substrate mounting portion 961, and a pattern member 970.

The pattern member 970 is formed at a surface of the first support portion 963 and the second support portion 965 opposite to each other. One surface of the pattern member 970 contacts the first support portion 963 and the second support portion 965, and an uneven pattern is formed on the other surface. The other side is the reverse side of the one side.

When the fixing member 960 is attached to the pipe 110, the other surface of the pattern member 970, on which the concave-convex pattern is formed, contacts the outer wall of the pipe 110. At this time, the uneven pattern increases the friction between the pattern member 970 and the outer wall of the pipe 110. Therefore, when the fixing member 960 is attached to the pipe 110, the friction force is increased by the pattern member 970, so that the fixing member 960 can be prevented from sliding from the smooth outer wall of the pipe 110.

That is, according to the ninth embodiment, the fixing member 960 can be more firmly fixed to the pipe 110 by the pattern member 970.

Fig. 15 schematically shows a structure of a fixing member 960 attached to a pipe 110 in a water purifier 1000 according to a tenth embodiment in plan view.

According to the tenth embodiment, a portion of the first supporting portion 1063 and the second supporting portion 1065 have a curved structure. At this time, the other ends of the first and second supporting portions 1063 and 1065 are bent to face each other.

In this case, the fixing member 1060 may be fixed to the pipe 110 in the same manner as the seventh embodiment. In the tenth embodiment, the surfaces of the other end of the first support portion 1063 and the other end of the second support portion 1065 facing each other are in contact with the outer wall of the pipe 110.

Although not shown in fig. 15, the fixing member 1060 according to an embodiment of the present invention may further include a buffer member (870 of fig. 13) of the eighth embodiment or a pattern member (970 of fig. 14) of the ninth embodiment. At this time, the buffer member 870 and the pattern member 970 are formed at the other ends of the first support portion 1063 and the second support portion 1065 that are in contact with the outer wall of the pipe 110.

Fig. 16 is an exemplary view showing a water purifier according to an eleventh embodiment of the present invention.

Fig. 16 schematically shows a structure of a fixing member 1160 attached to a pipe 110 in a water purifier 1100 according to an eleventh embodiment in plan view.

According to the eleventh embodiment, if a predetermined force is applied in one direction, the first and second supporting parts 1163 and 1165 are bent inward to be wound. Further, if a force in a direction opposite to the direction is applied to the first and second support portions 1163 and 1165 wound by bending, the first and second support portions 1163 and 1165 can be re-unfolded into a linear form. For example, the first support 1163 and the second support 1165 include iron in a Roll (Roll) shape.

As described above, by applying a constant force to the first support portion 1163 and the second support portion 1165, the first support portion 1163 and the second support portion 1165 can be wound around the outer wall of the pipe 110, and the fixing member 1160 can be fixed to the pipe 110.

Although not shown in fig. 16, the fixing member 1160 according to an embodiment of the present invention may further include a buffer member (870 of fig. 13) of the eighth embodiment or a pattern member (970 of fig. 14) of the ninth embodiment. At this time, the buffer member 870 and the pattern member 970 may be formed only on one of the first support portion 1163 and the second support portion 1165 that are in contact with the outer wall of the pipe 110. Or the buffer member 870 and the pattern member 970 may be formed at both the first supporting part 1163 and the second supporting part 1165.

In the seventh to eleventh embodiments of the present invention, a case is described in which the support portions of the fixing members 760, 860, 960, 1060, 1160 include the first support portions 763, 863, 963, 1063, 1163 and the second support portions 765, 865, 965, 1065, 1165. However, the supporting portions are not necessarily constituted by the first supporting portions 763 to 1163 and the second supporting portions 765 to 1165. The support portion may be formed only on one side of the substrate mounting portions 761, 861, 961, 1061, 1161. Also, the support portion may be formed in plurality on one side or both sides of the substrate mounting portions 761 to 1161. The support portions may be formed at positions and numbers different from those of ordinary skill in the art, as long as the fixing members 760 to 1160 can be fixed to the pipe 110.

The fixing members 760, 860, 960, 1060, 1160 of the seventh to eleventh embodiments of the present invention may be fixed to the pipe 110 by elastic force. Such fixing members 760 to 1160 can be easily fixed to any form of piping 110. Further, even if the fixing members 760 to 1160 are fixed to the pipe 110, the position is easily changed and the attachment and detachment are very easy. That is, since the positions where the fixing members 760 to 1160 can be attached are not limited, the light source module 130 can be arranged as needed regardless of the portion of the piping 110. Also, the fixing members 760 to 1160 are easily detached from the fixed pipe 110 to be attached to the pipe 110 of another water purifier, even without additional equipment and technology. Therefore, the fixing members 760 to 1160 are easily transferred to the water purifier requiring sterilization of the pipe 110 and installed. Also, since it is not necessary to replace the fixing members 760 to 1160 mounted with the light source module 130 when the water purifier is replaced, there is an economical advantage.

Although the various embodiments of the present invention have been described above, the present invention is not limited to the various embodiments and features described above, and various modifications and changes may be made without departing from the technical spirit of the scope of the claims of the present invention.
