Description

Ultraviolet sterilizer of near sterilization method and water purifier using the same

The present invention relates to a drinking water sterilizer using ultraviolet sterilizing power and a water purifier using the same. More particularly, the present invention relates to a device for sterilizing microorganisms such as E. coli in water and a water purifier equipped with the same. will be.

Recently, due to severe water pollution, the distrust of tap water is very high, while the standard of living and hygiene of the people is greatly improved, and the desire for safe drinking water is greatly increased. In response to these demands, many water purifiers are used.

The simplest type of water purifier of the prior art is to filter out solid contaminants present in the water by using various filtration devices such as filters, brine, and elvan, and to remove and remove harmful chemicals. Collected in the reservoir, it is configured in such a way that can be taken out through the water inlet if necessary.

Recent water purifiers have functions to sterilize microorganisms, such as viruses and bacteria, present in the water of the reservoir using various sterilization means. In addition to the basic filtration and sterilization functions described above, a water purifier having a function of heating and cooling water and providing ice has emerged.

The basic configuration of the conventional water purifier is as shown in Figure 1, by taking the water of the reservoir (2), the reservoir (2), and the reservoir (2) for storing the filtered water inside the body forming the appearance A water supply pipe (4) connected to an external water supply device such as a heating tank (3) for heating and producing hot water by heating to supply water to the water storage tank, and installed in the middle of the water supply pipe to filter solids in the water and adsorb harmful chemical components. A filter (5) to be installed inside the reservoir to sterilize microorganisms in the water (6), a power supply (7) for supplying electricity to each part of the water purifier, and to cool the water of the hydrogen The cooling device 8 etc. which produce a refrigerant | coolant are comprised.

The water purifier uses a lot of ultraviolet sterilizers as sterilizers 6 for sterilization, and is typically installed in the form of installing an ultraviolet lamp in the reservoir 2 as shown in FIG. UV lamps may be installed on the top or side of the reservoir. However, the germicidal power of the UV lamp is sterilizing only in close proximity to the lamp, and since UV rays do not penetrate far into the water, the germicidal power of the UV lamp sharply decreases. Therefore, in order to sterilize all the water in a large water tank (usually 150mm to 250mm in height and 150mm to 300mm in height) to a sufficient degree, the UV lamp should be turned on for a long time so that all the water in the tank can pass around the UV lamp by convection. There are many, short life of the ultraviolet lamp, even if there is a problem that does not sterilize to a sufficient degree.

And even if the water inside the reservoir (2) is temporarily sterilized, in the stagnant water far away from the sterilization apparatus, bacteria that penetrate from the outside can be a problem again.

In particular, commercial water purifiers are used by a large number of people in a relatively short time (lunch time, etc.), so they are often taken out and drinking before the water in the reservoir is sufficiently sterilized, which is a hygienic problem. The problem is that the energy efficiency is low because the UV lamp is kept on even during the time of not growing or using it again.

As described above, a water purifier equipped with a conventional ultraviolet sterilizer has a problem that the ultraviolet lamp must be turned on for a long time, thus, the electricity consumption is high, the life of the ultraviolet lamp is short, and the sterilization is not performed to a sufficient degree.

Therefore, the instant sterilization is performed at the moment of drinking water to reduce the consumption of electricity, increase the use time of expensive ultraviolet lamps, and also can purify perfectly sterilized water. And water purifier using it.

UV sterilizer of the present invention is a type of tube sterilized in one end, the inlet pipe is connected to the side of the upper side, the outlet pipe is connected to the bottom or bottom side, the top is blocked in the form of a UV lamp coupled stopper It is composed. A narrow gap is formed between the ultraviolet lamp and the inner wall of the tube, and sterilization is caused by the ultraviolet light emitted from the ultraviolet lamp as the water passes through the gap.

The water purifier using the ultraviolet sterilizer of the present invention is attached to the ultraviolet sterilizer to the cold water outlet of the conventional water purifier, so that the water taken out when taking out the water for drinking cold water is instantaneously sterilized while passing through the ultraviolet sterilizer. .

The close sterilization method of the present invention is perfect sterilization because the ultraviolet rays are irradiated from the very close part of the surface of the ultraviolet lamp while the water flows through the narrow gap between the ultraviolet lamp and the inner wall of the tube. In addition, since the ultraviolet light is turned on only when the water is taken out of the ultraviolet sterilizer of the present invention, the use period of the ultraviolet light is long, and the maintenance and maintenance cost is low.

The water purifier using the UV sterilizer of the present invention is sterilized instantaneously while the water taken out to drink cold water passes through the UV sterilizer, thus saving electricity because the UV lamp does not need to be turned on for a long time to sterilize the water in the reservoir. . And since the sterilized water is directly sterilized, there is no fear of regrowth of bacteria.

UV sterilizer of the present invention is a very simple structure, can be easily attached to the existing water purifier.

In the present invention, the ultraviolet sterilizer 6 of the close sterilization method, as shown in (a) of FIG. 2, has an inlet tube 62 provided at one end of a tube-shaped body 61 and an upper side of the body 61. ), The outlet pipe 63 provided on the bottom or bottom side of the body 61, the stopper 64 blocking the upper opening of the body 61, the ultraviolet lamp 65 is coupled to the stopper 64, And it is composed of an electric socket 66 coupled to the stopper 64 is exposed to the outside.

The body 61 is made of stainless steel, etc., which does not cause corrosion, but one end is sealed and the other end is preferably made so that female threads are formed on the inner wall.

The inlet pipe 62 and the outlet pipe 63 are short pipes that allow the hose to be coupled to each other, and are attached to the body by a hole or the like. The water inlet pipe 62 and the water outlet pipe 63 may be mutually changed in position.

Plug 64 is to be coupled to the upper opening of the body 61, the ultraviolet lamp 65 is coupled to the bottom, the upper end of the electric socket for supplying electricity to the ultraviolet lamp is coupled. In order to prevent water from penetrating into the side of the stopper, a sealing material 641 such as an O-Ribg is fitted, and it is preferable to form a male screw for engaging with the body 61. And when the body 61 and the stopper 64 is screwed, it is convenient to form two or more tool grooves 642 for turning the stopper on the top surface of the bar.

The ultraviolet lamp 65 is a tube shape in which a filament is built in a quartz tube, and various outputs are produced and marketed. In the case of the water purifier of the present invention, an output of 10 W is sufficient.

The electrical socket 66 is manufactured in a form that can be plugged in to supply external electricity. Since a pair of sockets and plugs for this purpose are manufactured and marketed in various ways, a suitable standard may be selected and attached. In some cases, a wire 661 extending from the ultraviolet lamp 65 may be extended to be connected directly to an external wire without using a separate electric socket.

In the present invention, the ultraviolet sterilizer 6 has a narrow gap formed between the outer wall of the ultraviolet lamp 65 and the inner wall of the body 61, and the water introduced from the water inlet pipe 62 passes through the water outlet pipe 63. It is spilled out and sterilized by ultraviolet rays while the water passes through the gap. Since the size of the gap is about several millimeters, the sterilization effect of the ultraviolet rays is very strong in the area close to the ultraviolet lamp, so that the water is sterilized to a sufficient degree for a few seconds as the water passes through the gap.

When the water flows through the gap between the outer wall of the ultraviolet lamp 65 and the inner wall of the body 61 in the ultraviolet sterilizer 6 of the present invention, when the water flows while turning around the ultraviolet lamp 65, the water is exposed to ultraviolet rays. The longer the time it takes, the higher the sterilization effect. To this end, as shown in FIG. 3, the inlet pipe 62 may be attached to be offset from the center of the body 61. In this case, the water flowing through the water inlet pipe 62 at a constant flow rate flows while turning along the outer wall of the ultraviolet lamp 65.

In addition, as shown in FIG. 4, when the turning groove 643 is formed in the stopper 64 so that the turning groove comes to the water inlet pipe 62, water entering the water inlet pipe changes direction in the turning groove. It flows while turning along the outer wall of the ultraviolet lamp 65.

When the ultraviolet sterilizer 6 is installed inside the water storage tank 2 of the water purifier, the water purifier can be configured more compactly. As described above, in the case of the ultraviolet sterilizer 6 installed inside the water storage tank 2 of the water purifier, it is preferable to extend the inlet pipe 62 along the lower end of the body 61 as shown in FIG. good. When the water inlet pipe is configured in this manner, when the UV sterilizer 6 is vertically coupled to the inside of the water tank 2, water at the bottom of the water tank is introduced into the UV sterilizer 6 through the water inlet pipe 62. Inflow.

In a conventional water purifier, since hot water is taken out by heating, sterilization occurs by heat in the heating process, and thus, no separate sterilizer is required. For cold water, a sterilizer as in the present invention is required. The water purifier which can use cold water cools the water in the water tank by winding a cooling coil 22 on the outside of the bottom of the water tank 2, and the cooled water sinks toward the bottom of the water tank by increasing the specific gravity. Therefore, when the inlet pipe 62 of the ultraviolet sterilizer 6 is extended toward the bottom of the reservoir, cold water of the lowest temperature can be taken out and drinking.

The UV sterilizer 6 of the close sterilization method may be mounted inside the reservoir of a conventional water purifier as shown in FIG. 5, or installed outside the reservoir 2 such as the bottom of the reservoir as shown in FIG. 6. Can be used.

The water purifier using the UV sterilizer 6 of the close sterilization method is configured similarly to a conventional water purifier. As shown in FIGS. 5 and 6, the water purifier body 1 forming the external shape and the water filtered inside the body. Reservoir (2) for storing the water, the water supply pipe (4) connected to the external water supply device, such as a heating tank (3), water pipes and the like to take the water from the reservoir (2) to produce hot water to heat the water supply tank (4) A filter (5) installed in the middle of the water supply pipe to filter solids in the water and adsorbing harmful chemical components, and an ultraviolet sterilizer (6) which is installed inside or outside the reservoir to sterilize microorganisms in the reservoir water; And a power supply 7 for supplying electricity to each part of the water purifier, and a cooling device 8 for producing a refrigerant required to cool the water of low hydrogen.

The body (1) is exposed to the outside to display the operating state of the water purifier and to enable the operation required for use, it is connected to the display operating unit 11, the reservoir (2) or the heating tank (3) and the hose to the hot water or It is preferable to provide a water intake device 12 or the like for allowing cold water to be taken out. And the water supply pipe 4 is provided with a control valve 41, such as a solenoid valve, and the water tank 2 is provided with a water level detector 21, when the water level of the water tank is lowered below a certain level, water can be automatically supplied from the outside. It is configured to be. The cooling coil 22 is wound around the lower end of the water storage tank 2 to cool the water at the bottom of the water storage tank while cooling the coolant generated in the cooling device 8 so that cold water can be supplied to the inside of the water storage tank. The drain pipe 24 is provided with a drain valve 23 for discharging the water to the outside for the purpose, and the heating coil 31 is wound around the heating bath 3 to enable hot water to be used. It is good.

When using hot water, it is advantageous to take out the high temperature water present at the upper end of the reservoir due to its relatively low specific gravity. For this, as shown in FIG. It is good to stretch to the top. And in order to prevent the hot water and cold water mixed in the water tank by convection, it is good to install a separator 25 in the middle of the water tank (2) having a water hole (26).

When the ultraviolet sterilizer 6 is mounted inside the water storage tank 2 of the water purifier, as shown in FIG. 5, the outlet tube 63 of the ultraviolet sterilizer 6 is projected to the outside of the storage tank 2, Connect the outlet pipe with the intake system and the hose. When the ultraviolet sterilizer 6 is mounted on the outside of the water storage tank 2 of the water purifier as shown in FIG. 6, the inlet pipe 62 of the ultraviolet sterilizer 6 is inserted into the inside of the low casting tank 2 and discharged. The pipe 63 is connected to the intake apparatus and a hose.

In addition, a sensor is installed near the intake device 12 to detect that a cup or the like is placed in the water purifier to take out cold water, to detect a flow rate of a hose connected to the cold water intake device 12, or to use a water purifier. The water purifier may be configured by supplying electricity to the ultraviolet lamp 65 of the ultraviolet sterilizer 6 to sterilize water only immediately before using the water purifier, for example, by approaching the water purifier.

When the water purifier is operated in this manner, the ultraviolet lamp is turned on only during use, so that the ultraviolet lamp 65 can be used for a long time, which saves electricity.

The present invention can be used in the water purifier which is a drinking water supply device for home or business.
