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 exemplary embodiment fixes the light source module 130 to the pipe 110 by using the fixing member 160 to sterilize water that moves through the pipe 110 or accumulates in the pipe 110. do. In describing the present embodiment, description of general components of a known water purifier such as a water storage unit and a water purifier is omitted.

The pipe 110 is a passage through which water moves to be discharged to the outside. When the water outlet (not shown) of the water purifier 100 is opened, the water moves through the pipe 110 in the water storage unit (not shown) and is discharged to the outside through the water outlet. In addition, when the water outlet is closed, the water outlet is blocked in the pipe 110, the water that is not discharged to the outside is accumulated. If water does not flow and accumulates in a space, it may be contaminated by contaminants such as bacteria or bacteria.

The opening 111 is formed in the pipe 110. Through the opening 111, the germicidal ultraviolet light of the light source module 130 is irradiated into the pipe 110. The opening 111 may be sized in consideration of the irradiation angle of the light source module 130 or the emission range of sterile ultraviolet light. The germicidal ultraviolet emission range of the light source module 130 may vary depending on the number of the light sources 132 or the structure in which the plurality of light sources 132 are disposed.

The fastening part 150 is formed on the outer wall of the pipe 110. The fastening part 150 is coupled to the fixing member 160 so that the fixing member 160 is fixed to the pipe 110. The fastening part 150 is formed to have a long length in one direction, as shown in the figure. In addition, the protrusion 151 is formed on one side of the fastening part 150. The protrusion 151 is formed to have a structure corresponding to the locking groove 167 of the fixing member 160. In addition, the fastening part 150 is a curved surface having a curvature on the side.

The outer wall of the pipe 110 is formed with a seating portion 170 of the structure protruding to the outside. The seating unit 170 may include a first protrusion 171 and a second protrusion 172. The first protrusion 171 and the second protrusion 172 are formed to surround the circumference of the opening 111. In addition, the first protrusion 171 and the second protrusion 172 are spaced apart from each other, the second protrusion 172 is located in the inner region of the first protrusion 171. Referring to FIG. 1, the second protrusion 172 extends outward from the opening inner wall 112. Here, the opening inner wall 112 is an inner wall of the pipe 110 forming the opening 111. In addition, the height of the second protrusion 172 is smaller than the height of the first protrusion 171. Here, the heights of the first protrusion 171 and the second protrusion 172 is a length protruding from the outer wall of the pipe 110 to the outside.

The sealing member insertion groove 115 into which the sealing member 180 is inserted is formed between the first protrusion 171 and the second protrusion 172. The sealing member 180 is formed of an elastic material 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 is a distance between the upper surface in contact with the outer wall of the pipe 110 and the lower surface in contact with the transparent window 120. Therefore, when the sealing member 180 is inserted into the sealing member insertion groove 115, the sealing member 180 protrudes from the second protrusion 172. When the fixing member 160 is mounted on the pipe 110 so that the sealing member 180 protrudes more than the second protrusion 172, the transparent window 120 may be in close contact with the second protrusion 172. Since the transparent window 120 and the second protrusion 172 are in close contact with each other, the pressure between the fixing member 160 and the pipe 110 may be reduced between the opening 111 of the pipe 110 and the transparent window 120. It can be sealed more firmly.

In addition, since the sealing member 180 is formed of an elastic material, it is possible to buffer the pressure applied to the transparent window 120 when the fixing member 160 is mounted on the pipe 110. Therefore, the sealing member 180 may prevent the transparent window 120 from being damaged by the pressure applied to the transparent window 120 when the fixing member 160 is mounted on 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 in the wavelength band having a sterilizing effect. That is, the light source module 130 emits sterile ultraviolet light. For example, sterile ultraviolet light is ultraviolet light in the wavelength range of 300 nm to 290 nm. In addition, 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 mounted to the fixing member 160, and 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. Irradiate UV rays with

The fixing member 160 is fixed to the pipe 110. When the fixing member 160 is fixed to the pipe 110, the light source module 130 mounted on the fixing member 160 may radiate sterilizing ultraviolet rays into the pipe 110 through the opening 111 of the pipe 110. It becomes possible.

According to the present embodiment, the fixing member 160 includes a through hole 164, a substrate mounting part 161, a fastening groove 165, a transparent window pressing part 168, and a protrusion 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 is a light source 132 of the light source module 130 mounted on the fixing member 160 is located, the passage through which sterilized ultraviolet light passes.

The substrate mounting portion 161 is formed on the bottom surface of the fixing member 160. The substrate mounting portion 161 protrudes downward from the lower surface of the substrate 131, and has a structure in which the protruding end is bent. Therefore, the substrate mounting portion 161 has a groove into which the side surface of the substrate 131 can be inserted. When both side surfaces of the substrate 131 are inserted into the substrate mounting unit 161 of this type, the light source module 130 is mounted to the fixing member 160.

The upper surface of the fixing member 160 is formed with a transparent window pressing portion 168 and the projection insertion groove 169.

The transparent window pressing unit 168 extends from the inner wall of the fixing member 160 forming the through hole 164 and protrudes upward. At this time, the height of the upper surface of the transparent window pressing unit 168 is lower than the upper surface of the fixing member 160 surrounding the outer periphery of the protrusion insertion groove 169.

The transparent window pressing unit 168 presses the transparent window 120 when the fixing member 160 is mounted on the pipe 110. The transparent window 120 pressurizes the sealing member 180 by the force pressed from the transparent window pressing part 168, and thus the sealing between the pipe 110 and the fixing member 160 is firm.

The length of the inner wall of the fixing member 160 constituting the transparent window pressing unit 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 is the distance from the upper surface to the lower surface of the fixing member 160. In addition, the thickness of the light source 132 is a distance from the lower surface to the upper surface in contact with the upper surface of the substrate 131. Therefore, when the light source module 130 is mounted on the fixing member 160, the light source 132 is positioned in the through hole 164, but is spaced apart from the transparent window 120. Therefore, it is possible to prevent the light source 132 and the transparent window 120 from being in close contact with each other or crashing.

The protrusion insertion groove 169 is formed along the circumference of the transparent window pressing part 168. The protrusion insertion groove 169 is in the form of a recess formed in the transparent window pressing portion 168. When the fixing member 160 is mounted on 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 mounted on the pipe 110, the outer wall of the pipe 110 and the upper surface of the fixing member 160 may be in close contact with each other.

A fastening groove 165 is formed on the lower surface of the fixing member 160. The fastening groove 165 is configured to be fastened with the fastening part 150 of the pipe 110. The fastening groove 165 is located outside the through hole 164 and the protrusion insertion groove 169.

A part of the fastening groove 165 is provided with a fastening part insertion hole 166 into which the fastening part 150 of the pipe 110 can be inserted. The fastening part insertion hole 166 is a hole penetrating the fixing member 160. The inner wall of the fixing member 160 constituting the fastening part insertion hole 166 has a curvature to correspond to the fastening part 150.

A locking groove 167 is formed on an inner wall of the fixing member 160 constituting the locking groove 165. The locking groove 167 is a groove structure corresponding to the protrusion 151 of the coupling part 150 of the pipe 110. . When the protrusion 151 of the fastening part 150 is inserted into the locking groove 167, the fixing member 160 is mounted on the pipe 110.

According to the present embodiment, the fastening part 150 of the pipe 110 is inserted into the fastening part insertion hole 166 of the fastening member 160, and then the fastening part 150 is rotated in one direction. Protruding portion 151 of the) is fitted into the locking groove 167 of the fixing member 160. In this manner, the fixing member 160 is mounted to the pipe 110.

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

In addition, although not shown in the drawings, the light source module 130 may be further fixed to the fixing member 160 by using a screw in order to more securely fix the light source module 130 to the fixing member 160.

The light source module 130 is located on the outer wall of the pipe located between the water reservoir and the water outlet. Alternatively, when the water purifier 100 does not include a water storage unit, the light source module 130 is positioned between the inlet and the water outlet through which the water is not purified, and is located closer to the water outlet. Therefore, the water purifier 100 may sterilize the water before sterilizing the water and before discharging it to the outside, rather than storing the sterilized water. In addition, when the purified water is stored in the water storage unit, the water purifier 100 may sterilize the water once more before the water is discharged to the outside through the outlet. As such, the water purifier 100 according to the present embodiment is sterilized before water is discharged, and thus the water purifying function is improved. If the light source module 130 is fixed to the pipe close to the water outlet, since the water can be sterilized immediately before the discharge, the water purification efficiency of the water purifier 100 can be improved. In addition, if the light source module 130 is fixed to the upper portion of the bent pipe 110, the sterilized ultraviolet light may be irradiated to the inside of the pipe 110 continued in the lower direction. That is, since the irradiation range and irradiation area of the sterilizing ultraviolet light are widened, the water purifier 100 can sterilize a large amount of water at once.

5 is an exemplary view showing a water purifier according to a second embodiment of the present invention.

5 is a side cross-sectional view of the water purifier 200 according to the second embodiment. In the description of the water purifier 200 according to the second embodiment, description of the same configuration as the water purifier (100 of FIGS. 1 to 4) according to the first embodiment will be omitted. The omitted description will be referred to the description of FIGS. 1 to 4 as the first embodiment.

Referring to FIG. 5, the water purifier 200 according to the second embodiment has a structure different from that of the water purifier (100 of FIGS. 1 to 4) and the inner wall of the opening (112 of FIG. 3) according to the first embodiment.

At least a portion of the opening inner wall 212 is formed to have a slope. Referring to FIG. 5, the opening inner wall 212 facing each other has an inclination such that the inner wall 212 gradually moves away from the middle to the inside of the pipe 110. Therefore, the opening 111 has a structure in which the diameter gradually increases toward the inside of the pipe 110 in the middle.

According to the present embodiment, the inclination of the inner wall 212 of the opening may be changed according to the light irradiation angle of the light source module 130. That is, since the opening inner wall 212 is formed to have a slope, the germicidal ultraviolet light emitted from the light source module 130 may be irradiated into the pipe 110 without hitting the possible opening inner wall 212.

When the germicidal ultraviolet rays hit the inner wall while passing through the opening, the germicidal ultraviolet rays are not all reflected and directed toward the inside of the pipe 110. Some of the germicidal ultraviolet light that strikes the inner wall of the opening may be absorbed by the inner wall. In addition, the other part of the sterile ultraviolet light is reflected from the inner wall of the opening, it may be reabsorbed by the light source 132 toward the other than the inside of the pipe 110 or toward the light source module 130.

However, the water purifier 200 according to the present exemplary embodiment may reduce a phenomenon in which germicidal ultraviolet rays collide with the opening inner wall 212 by the opening inner wall 212 having a slope.

In addition, since the water purifier 200 faces each other with the opening inner wall 212 facing each other toward the inside of the pipe 110, the sterilizing ultraviolet light is directed toward the inside of the pipe 110 when it hits the opening inner wall 212 having the slope. Can be reflected to.

Therefore, the water purifier 200 according to the present embodiment may improve the sterilization efficiency and the water purification efficiency of water by reducing the loss of sterilization ultraviolet light directed toward the inside of the pipe 110 by the opening inner wall 212 having the slope.

In the present exemplary embodiment, the opening inner wall 212 has an inclination from the middle portion, but the structure of the opening inner wall 212 is not limited thereto. For example, the opening inner wall 212 may have a structure having an inclination from the inlet of the opening 111. As such, the portion and the inclination angle of the opening inner wall 212 are in consideration of the portion of the light source module 130 in which the germicidal ultraviolet light is emitted, the irradiation angle, the distance between the light source module 130 and the opening 111, and the like. can be changed.

6 to 8 are exemplary views showing a water purifier according to a third embodiment of the present invention.

6 is an exploded view of some components constituting the water purifier of the third embodiment, FIG. 7 is a plan view in which the components of FIG. 6 are combined, and FIG. 8 is a side cross-sectional view of the water purifier.

In the description of the water purifier 300 of the third embodiment, a description overlapping with the water purifier 300 of the first embodiment will be omitted.

According to the third embodiment, the water purifier 300 includes a pipe 110, a light source module 330, and a 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 screwing.

The outer wall of the pipe 110 is formed with a seating portion 370 protruding to the outside. The first sealing member 381, the second sealing member 382, and the transparent window 120 are mounted on the seating portion 370.

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

The transparent window 120 is positioned 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 seating 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 pressed by the substrate 331, and thus, the opening portion of the pipe 110 is formed. 111 may be tightly sealed.

In addition, the second sealing member 382 should be thicker than the thickness of the light source 332 when pressed by the substrate 331. When the second sealing member 382 is compressed to be thicker than the light source 332, when the light source module 330 is fixed to the pipe 110, the light source 332 and the transparent window 120 are prevented from colliding with each other. can do.

In addition, a fastening part 311 having a protruding structure is formed on an outer wall of the pipe 110. The fastening part 311 has a fastening groove 312 into which one end of the fastening member 340 is inserted. The upper surface of the fastening part 311 may be located lower than one surface of the second sealing member 382 seated on the seating part 370. Here, one surface of the second sealing member 382 is a surface in close contact with the substrate 331. Therefore, when the light source module 330 is fixed to the pipe 110 using the fastening member 340, the substrate 331 presses the second sealing member 382. As a result, since the first sealing member 381, the transparent window 120, and the second sealing member 382 are in close contact with each other by a strong force, the opening 111 of the pipe 110 may be tightly sealed.

In addition, the outer wall of the pipe 110 is formed with a locking portion 313 having a structure in which the end is bent like a hook. The locking portion 313 may include a groove into which a portion of the substrate 331 may 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, the heat radiation efficiency is improved. In addition, since the substrate 331 is made of metal, it is hard. Therefore, when the substrate 331 is fixed to the pipe 110, the substrate 331 may be prevented from being bent due to a force by 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 in one portion of the substrate 331 of the light source module 330. In addition, a fixing hole 334 through which the locking portion 313 of the pipe 110 passes is formed at another portion of the substrate 331.

The locking portion 313 of the pipe 110 passes through the fixing hole 334 and the substrate 331 is caught by the substrate 331. At this time, the inner surface of the substrate 331 that forms 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 bent portion of the locking portion 313. The locking portion 313 prevents the substrate 331 from being spaced apart from the outer wall of the pipe 110 by a predetermined distance or more. In addition, the locking portion 313 prevents the substrate 331 fixed to the pipe 110 from moving so that the light source 332 is separated from 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 height of the height from the outer wall of the pipe 110 to the upper surface of the fastening part 311 and the thickness of the substrate 331. Same as sum. Here, the bottom surface of one end of the locking portion 313 is a portion in contact with the bottom surface of the substrate 331.
