Description

Water purifier with LED {WATER PURIFIER HAVING UV LED}

The present invention relates to a water purifier having a UV LED, and more particularly, to a water purifier in which ultraviolet rays emitted from the UV LED sterilize the discharge valve, the coaster and the like.

Recently, due to the development of the industry, the water quality of human drinking water is greatly polluted. Water pollution is known to be caused by toxic organic substances, gaseous pollutants or various bacteria. Accordingly, a number of water purifiers for providing clean water that can be drunk are widely distributed on the market.

When using the water purifier in homes, institutions, or offices, germs and dust floating in the air are buried at the entrance of the discharge valve, and the discharge valve and food are in contact while pouring water to eat coffee or cup ramen. The discharge valve always inevitably contains a large amount of bacteria. In addition, when drinking coffee or tea, the contents are thrown into the cup holder, or the water droplets splashing on the contents of the cup while pouring water through the discharge valve are buried in the water purifier body and the cup support. Inevitably there will be a large amount of bacteria.

The present invention relates to a water purifier that sterilizes a discharge valve, a water purifier body, a coaster, etc. using a UV LED, and the related invention relates to a water purifier, in which the name of the invention is "LED disinfection water tap". It was presented in -0628705. However, although the patent invention has a concept of sterilizing the nozzle of the discharge valve, it is not easy to efficiently arrange the UV LED inside the nozzle of the narrow discharge valve, and mentions nothing about the waterproof structure of the UV LED to which water directly comes into contact. There is no In addition, the discharge valve is closed for most of the time, and in the above-described patent invention, since the UV LED is irradiated only inside the nozzle of the discharge valve, the nozzle end of the discharge valve is hardly disinfected and sterilized. It can be seen that only the rod stopper that blocks the tip is sterilized. As a result, this registration invention can be seen that the sterilization effect is very minimal for the nozzle of the discharge valve that food is buried or touched by hand and bacteria are multiplied. In addition, there is no concept of sterilization using UV LEDs for germ-containing cup holders or other water purifier bodies as well as nozzles of discharge valves.

The embodiment provides a water purifier with UV LEDs capable of sterilizing the discharge valve directly.

In the description of the embodiments, the criteria for up, down, left, right, up and down will be described with reference to the drawings unless otherwise noted. In the drawings, the size of each component or a specific portion constituting the components is exaggerated, omitted, or schematically illustrated for convenience and clarity of description. Therefore, the size of each component does not entirely reflect the actual size. Like numbers refer to like elements throughout the specification.

1 shows a simplified illustration of a body 10 having a receptacle 11. Referring to FIG. 1, the accommodating part 11 has five faces, and the five faces are the ceiling surface, the bottom surface, the back surface, the left side, and the right side with respect to the accommodating part 11 when viewed from the front. It is called. 3 to 5, the position of each component will be described with reference to five specified surfaces. As will be described later, the receiving portion 11 of the body 10 has a number of configurations for specifying the present invention, such as discharge valve 400, UV LED module 200, coaster 16, protective cover 13, The element is placed.

2 is a schematic diagram schematically showing the structure of the water purifier 1 according to an embodiment of the present invention. Referring to 2, the water purifier 1 according to an embodiment of the present invention, the water supply source 900 for providing water into the water purifier 1, purifying the contaminants and foreign substances of the water provided from the water supply source 900 To filter unit 800, the water reservoir 300 is stored, the UV LED module 200 disposed in the receiving unit 11, the control unit 500 for controlling the operation of the UV LED 210, the reservoir 300 Various components, such as a discharge valve 400 for extracting the water stored in the outside, the receiving portion 11 and the protective cover 13 for shielding the outside are disposed, and includes a body 10 forming an overall appearance. It may include components.

The water supply source 900 may be a tank for storing unpurified water and may also be a water pipe itself connected to a building from a water supply. In the present embodiment, the filter is a primary filter 810 for removing large impurities such as rust, soil, sand, secondary filter 820 for removing heavy metals, phenol, bacteria, etc. in the water by reverse osmosis, and finally It includes a third filter 830 to purify the water. However, the number of filters of the filter unit 800 may be different, and the function of each filter may be different. In addition, although the filter unit 800 is located inside the body 10 in FIG. 2, alternatively, the filter unit 800 may be located outside the body 10, and furthermore, the water purifier 1 according to the present embodiment may be disposed outside. When used for the purpose of sterilizing sufficiently purified water, the filter unit 800 itself may be omitted.

The operating time, operating cycle, light intensity, etc. of the UV LED 210 on the UV LED module 200 is controlled by the controller 500. The circuit board 220 is connected to the controller 500. As shown in FIG. 2, a connection line may be interposed between the UV LED module 200 and the control unit 500, or the UV LED module 200 and the control unit 500 may be directly connected without the connection line.

Then, when the user opens the discharge valve 400, water is discharged to the outside of the water purifier (1). There may be only one discharge valve 400, but it is common that the discharge valve 400 for cold water and hot water has a total of two discharge valves 400, one or three discharge valves 400.

3 is an enlarged right sectional view of an essential part of the water purifier 1 according to the first embodiment of the present invention.

The body 10 of the water purifier has an accommodating portion 11 at the front side, and a discharge valve 400 is provided at the rear side of the accommodating portion 11, in other words, in an area lower than the discharge valve 400, that is, the discharge valve. The cup support 16, which is located below the 400 and can place the cup, is installed at the bottom of the receiving portion 11, and is located in an area higher than the discharge valve 400, that is, of the receiving portion 11. UV LED module 200 is installed on the ceiling surface. And the protective cover 13 which shields the accommodating part 11 from the outside is provided in the front of the accommodating part 11, with the accommodating part 11 covered. The accommodating part 11 does not necessarily need to exist only in the front of the body 10 of a water purifier, but may be in a side surface. Therefore, if the accommodating part 11 exists in the side surface of the body 10 of a water purifier, it is natural that the protective cover 13 is also provided in the side surface of the body 10 of a water purifier.

On the other hand, there is a hinge at the boundary between the protective cover 13 and the ceiling surface of the receiving portion 11, the protective cover 13 is coupled to the receiving portion 11 through the hinge, the protective cover 13 Can open and close. However, unlike the present embodiment, the hinge may be formed at a boundary where the right side of the protective cover 13 and the receiving portion 11 meet, and at the boundary where the left side of the protective cover 13 and the receiving portion 11 meet. It may be formed, or may be formed at the boundary where the protective cover 13 and the bottom surface of the receiving portion 11 meet. Furthermore, the protective cover 13 does not necessarily have to use a hinge in order to be coupled with the receiving portion 11, but a rail is formed to push and close the protective cover 13, and the protective cover 13 is formed by the rail. It may be a structure that is guided and sliding. The protective cover 13 may be designed to be detachable.

The protective cover 13 is installed to prevent ultraviolet rays emitted from the UV LED module 200 from radiating to the outside of the water purifier 1 to cause damage to a person. Thus, as shown in FIG. 3, the UV blocking film 14 is covered on the surface of the receiving portion 11 side of the protective cover 13. However, the ultraviolet blocking film 14 may be attached to the outer surface of the protective cover 13, and the ultraviolet blocking film 14 is functionally intended to prevent ultraviolet rays from leaking out of the water purifier 1, and thus, the ultraviolet blocking film is necessarily made. It is not necessary for the 14 to be formed as a separate layer to cover the protective cover 13, and the protective cover 13 itself may be formed of an ultraviolet blocking material.

The UV LED module 200 is installed on the ceiling surface of the accommodating part 11, and ultraviolet rays are emitted downward, so that the cup holder 16 is directly sterilized and the discharge valve 400 positioned on the optical path of the ultraviolet rays. Some surfaces can also be sterilized. The UV LED module 200 has a UV LED 210 that emits UV light directly, has a circuit board 220 on which the UV LED 210 is arranged, and additionally emits light from the UV LED 210. Preferably, the lens 230 further includes a lens 230 that helps protect the UV LED 210 and the circuit board 220 from moisture and assists light emission from the UV LED 210. In addition, the UV LED module 200 includes at least one UV LED 210, the UV LED 210 has a dominant wavelength of less than 400nm. For example, it is preferable to generate ultraviolet rays having a peak wavelength of 200 to 350 nm, and to further limit the ultraviolet rays having a peak wavelength of 265 to 340 nm.

LEDs typically have a light emission angle of between 120 ° and 160 ° or even have Lambertians. Accordingly, even when the UV LED module 200 is positioned to face the cup holder 16 vertically as shown in FIG. 3, ultraviolet rays emitted from the UV LED 210 are reflected from the inner surface of the receiving part 11. Therefore, when the inner surface of the accommodating part 11 is surrounded by the reflector 12 as shown in FIG. 3, the UV LEDs 210 having the same number and output without the reflector 12 are arranged, as compared with the case where the reflector 12 is not arranged. Sterilization efficiency is high. In FIG. 3, the reflector 12 is shown to be covered only on the rear surface of the accommodating part 11. However, if the reflector 12 is also covered on the ceiling, bottom, right and left sides of the accommodating part 11, sterilization efficiency will be higher. . However, since the intensity of the light decreases as the ultraviolet rays are reflected on the reflector 12, the UV LED module 200 of the first embodiment mainly aims to sterilize the coaster 16.

On the other hand, the reflecting film 15 covers the protective cover 13, the reflecting film 15, as well as the reflector 12 is to increase the sterilization efficiency of the ultraviolet light emitted from the UV LED 210. In FIG. 3, although the ultraviolet blocking film 14 is illustrated between the protective cover 13 and the reflective film 15, the UV blocking film 14 may be replaced with the protective cover 13. ), The relative position of the protective cover 13, the UV blocking film 14, the reflective film 15 can be changed. However, in order for the reflective film 15 to function properly, it is preferable that the reflective film 15 is formed on the surface of the receiving portion 11 side of the protective cover 13. The UV blocking film 14 may be integrally molded with the protective cover 13, and the reflective film 15 and the UV blocking film 14 may be integrally molded. The UV blocking layer 14 may be made of synthetic resin or metal, and may be formed of, for example, aluminum. When formed of aluminum or other metal, since the UV blocking film 14 can serve as the reflective film 15 at the same time, there is an advantage that can reduce the manufacturing cost. As a result, the reflective plate and the reflective film 15 has an advantage of increasing sterilization efficiency compared to the number and output of the UV LED 210 used.

4 is an enlarged right sectional view of the main part of the water purifier 1 according to the second embodiment of the present invention.

Since the second embodiment of FIG. 4 is basically the same as that of the first embodiment of FIG. 3, the descriptions overlapping with those described in the first embodiment will be omitted and only differences will be described. Compared to the first embodiment, the second embodiment differs only in the position of the UV LED module 200. In FIG. 4, the UV LED module 200 is inclined toward the rear side of the accommodating part 11, and is positioned to face toward the corner where the protective cover 13 and the ceiling surface of the accommodating part 11 meet. Therefore, if the first embodiment is mainly intended to sterilize the coaster 16, the second embodiment sterilizes the coaster 16, but the arrangement of the UV LED 210 to sterilize the top and front side of the discharge nozzle in earnest To have.

In the first embodiment, the ultraviolet light emitted from the UV LED 210 is mainly reflected by the reflectors 12 of the ceiling and bottom surfaces of the accommodating portion 11. In the second embodiment, the UV LED module 200 is used. ) Is positioned slightly inclined without facing the cuprest 16 vertically, so that the ultraviolet rays emitted from the UV LEDs 210 are not only the ceiling and bottom surfaces of the receiving portion 11, but also the receiving portion 11. The reflector 12 and the reflective film 15 on the back and side of the can be more easily reflected. Therefore, the second embodiment is superior in the sterilization effect of the entire accommodating portion 11 as compared with the first embodiment. However, the first embodiment has a better sterilizing effect on the coaster 16 than the second embodiment.

5 is an enlarged right sectional view of the main part of the water purifier 1 according to the third embodiment of the present invention. Since the third embodiment of FIG. 5 is basically the same as that of the first embodiment of FIG. 3, the descriptions overlapping with those described in the first embodiment will be omitted and only differences will be described. Compared to the first embodiment, the third embodiment differs only in the position of the UV LED module 200. In FIG. 5, the UV LED module 200 is installed on the coaster 16. Since the UV LED module 200 of this embodiment mainly sterilizes the discharge nozzle, in particular, sterilizes the nozzle part of the discharge nozzle, the UV LED module 200 is located directly below the nozzle part of the discharge valve 400. It is desirable to.

On the other hand, the UV LED module 200 of the first and second embodiments rarely directly touches the water discharged from the discharge nozzle, but since the UV LED module 200 of the third embodiment is located on the cup holder 16, the discharge nozzle In many cases, the water discharged from directly touches the UV LED module 200. Therefore, compared to the first and second embodiments, the waterproof property of the UV LED module 200 is important, and in order to prevent water from directly contacting the UV LED 210, the lens 230 is mounted on the UV LED 210. It is preferable to provide, or to interpose the waterproof ring between the UV LED 210 and the coaster 16. In addition, when the upper surface of the UV LED module 200 is located lower than the upper surface of the coaster 16, water accumulated in the coaster 16 is accumulated on the UV LED 210, the UV LED 210 and the circuit If water penetrates the substrate 220, a short may occur. Thus, it is preferable that the UV LED module 200 protrudes above the coaster 16 or is at least coplanar.

In addition, although not shown in the drawings, a fourth embodiment in which the first embodiment shown in FIG. 3 and the third embodiment shown in FIG. 5 are combined is also possible. Since the fourth embodiment is basically the same as the first and third embodiments, the descriptions overlapping with those described in the first and third embodiments will be omitted and only the differences will be described. In the first and third embodiments, the UV LED module 200 is located only on the ceiling surface or the bottom surface of the accommodating part 11, but in the fourth embodiment, the first UV LED module (located on the ceiling surface of the accommodating part 11) ( 200A) and the second UV LED module 200B located at the bottom of the receiving portion 11. Therefore, at least two UV LED modules 200 are installed in the fourth embodiment. The configuration other than the UV LED module 200 is the same as in the first and third embodiments.

In addition, although not shown in the drawings, the basic configuration is the same as that of the fourth embodiment, but the fifth embodiment in which only the position and installation angle of the first UV LED module 200A is possible is also possible. Since the fifth embodiment is basically the same as the fifth embodiment, the descriptions overlapping with those described in the fourth embodiment will be omitted and only the differences will be described. Compared to the fourth embodiment, the fifth embodiment differs only in the position of the first UV LED module 200A. That is, in the fifth embodiment, the first UV LED module 200A is inclined toward the rear side of the accommodating portion 11 and is biased toward the corner where the protective cover 13 and the ceiling surface of the accommodating portion 11 meet. Will be located. Therefore, if the first UV LED module 200A of the fourth embodiment is mainly for sterilizing the coaster 16, the first UV LED module 200A of the fifth embodiment sterilizes the coaster 16 but is discharged. The top and front sides of the nozzle are also for sterilization in earnest.

In the fourth embodiment, the first UV in the fifth embodiment is compared with the ultraviolet rays emitted from the first UV LED 210 mainly being reflected by the reflectors 12 of the ceiling surface and the bottom surface of the accommodating portion 11. Since the LED module 200A is positioned slightly inclined without facing the cuprest 16 vertically, the ultraviolet rays emitted from the first UV LEDs 210 may not only be exposed to the ceiling and bottom surfaces of the accommodating part 11. The reflector 12 and the reflective film 15 on the rear and side surfaces of the accommodating portion 11 may be more easily reflected. Therefore, the fifth embodiment is superior to the fourth embodiment in terms of the sterilization effect of the entire accommodating portion 11. However, the fourth embodiment has a better sterilizing effect on the coaster 16 than the fifth embodiment.
