Description

TANK HAVING ULTRAVIOLET RAYS STERILIZER}

The present invention relates to a water tank that is used as a water storage container in a water purifier, and more particularly, to a water tank in which an ultraviolet sterilization device capable of ultraviolet sterilization of bacteria and the like present in the water tank is embedded.

The water purifier is installed with a water tank capable of storing a certain amount of water for stable supply of water. In addition, an ultraviolet lamp is installed in the tank or in a piping system in which water is supplied in order to sterilize germs propagating in the water.

However, the prior art that is used for ultraviolet sterilization in water purifiers as described above had the following problems.

For example, in the case of the technique in which the ultraviolet lamp 4 is installed directly inside the glass bath 19 as shown in FIG. 5, the ultraviolet lamp 6 is supplied to the power supply 24 although the sterilization effect on water is effective. Because the ultraviolet rays emitted from the glass tank 19 is projected out of the glass tank 19 when exposed to the ultraviolet rays could adversely affect the eyes of the human body, particularly the eyesight could be greatly reduced. In addition, the UV lamp 6 is often damaged in the process of being installed inside the glass bath 19, and mercury encapsulated in the UV lamp 6 for the generation of ultraviolet rays is mixed in the water in the glass bath 19 and harmful to the human body. Had the risk of causing it. Therefore, in the case of the water tank 19 in which the ultraviolet lamp 6 is directly installed, it has been very difficult to handle since a great care must be taken in order to prevent damage of the ultraviolet lamp 6 in the storage or transportation process.

In addition, in the case of the technique of installing the ultraviolet lamp 6 in the supply system as shown in Figure 4, the ultraviolet lamp 6 is embedded in the rigid sealing pipe 15, so that the handling of the ultraviolet sterilization unit is somewhat easier. However, since the ultraviolet lamp is not visible to the naked eye, there is a problem in that it is difficult to check whether there is an operation or damage after installation. In addition, since the sterilization is performed during the flow of water in the supply system has a problem that the sterilization efficiency is very small because the duration of sterilization for the water is very short, only a few seconds to several minutes.

4 and 5, but not described above, reference numeral 1 denotes a power line for supplying power to an ultraviolet lamp, and reference numeral 12 denotes a tank lid. 16 and 17 are inlet and outlet pipes connected for inflow and outflow of water, respectively.

The present invention has been made to solve the problems of the prior art as described above, the sterilization efficiency is high by long time ultraviolet sterilization treatment of the water stored in the water tank by natural convection, and there is very little risk of damage to the UV lamp without exposing UV to the outside There is little fear of adversely affecting the human body, and its purpose is to provide a bath with a built-in ultraviolet sterilizer easy to handle.
