A water purifier having an electrolytic sterilization device

The present invention relates to a water purifier, and more particularly, an electrolytic sterilization kit is installed between a water tank of a water purifier or a cold / hot water purifier and a cock that discharges or blocks water, and thus the bacteria of secondary pollution propagated in the water tank are applied to the potential difference of electrolysis. The present invention relates to a water purifier and a cold / hot water machine installed with an electrolytic sterilization kit for supplying water sterilized by cold water cock by killing or erasing by indirect sterilization by radicals generated during direct sterilization and electrolysis.

As well-being winds blow across the society in recent years, the quality of water for people to drink is also required. Especially in drinking water that is directly connected to people's health, they are more interested in using water purifiers or cold and hot water in homes and offices. These water purifiers or cold and hot water are used to make hot water as a means of heating water and make cold water as a cooling means. The cold and hot water are connected to the cock through separate pipes, but bacteria and contaminants are also present in the purified drinking water discharged through the cock. .

A schematic configuration of a water purifier with a sterilizer according to the prior art associated with this study is shown in FIG. 1. Referring to Figure 1, a conventional water purifier equipped with a sterilizer sediment filter (101), sedimentation filter for removing particulate matter by receiving water such as tap water and ground water through the conduit 108 and the raw water switch 109 Passing through the boosting pump 102 for raising the water pressure of the water flowing from the 101, the pre-carbon filter 103 for adsorbing and removing chlorine and oxides from the water flowing from the boosting pump 102, the pre-carbon filter 103 A water is introduced into the membrane 104 for removing heavy metals or ionic substances from the water, and the post carbon filter 105 for receiving water from the membrane 104 and adsorbing and removing gaseous substances dissolved in the water. , A sterilizer 106 for accommodating the water discharged from the post carbon filter 105 and sterilizing microorganisms in the water, a storage tank 107 for storing the sterilized water in the sterilizer 106, and a pipeline 111 To open and close the water in the reservoir tank It can consist of switch 110.

It was. Reference numeral 112 is a switch for removing water.

The electrolytic sterilization kit 300 is not functioning due to failure, breakage or deterioration of the sterilizer 106, as well as in the case of sterilization of silver or antibacterial ball method, the activated carbon and antibacterial ball have a poor function due to their lifetime. In this case, the water is electrolytically sterilized immediately before being discharged through the cock, so that safe water sterilized in an aseptic state can be supplied.

Figure 3 is a view for explaining a bacteria propagation prevention method of the cold and hot water machine equipped with the electrolytic sterilization kit of the present invention, Figure 3 is a water tank 204 is placed on the upper side of the cold and hot water heater case 200, the cock 206, 208 It shows a cold and hot water machine of a well-known structure to supply cold and hot water to the user through.

Although not shown in the drawings, such a cold and hot water heater has a heating means for heating the water and a cooling means for cooling the water in the case 200. In this embodiment, the side of the conduit leading to the cock 206 side will be described as the cold water part, and the side of the conduit leading to the other cock 208 side will be described as the hot water unit.

A supply pipe 210 through which water is supplied is communicated between an inflow port of the cock 206 and the water tank 204 to supply water, and between the circulation port side of the cock 206 and the water tank. Bypass pipeline 212 is connected to the water tank 204 and the cock 206 forms a circulation path.

The cock 206 generally has an inlet port, an outlet port, and a circulation port, and these ports are configured to communicate with each other, and the outlet port is provided with a normal opening and closing member to open and close the outlet port according to a user's operation. It can have a structure. In addition, a small chamber is generally formed at the inlet side of the outlet port, so that water introduced into the chamber can go to the outlet port side or return to the circulation port side. As described above, the small chamber is provided at the inlet side of the inlet port so that water can circulate without congestion in the conduit when the outlet port is blocked, thereby allowing bacteria in the conduit section between the electrolytic sterilization kit 300 and the cock 206. This can prevent breeding.

And, the end of the bypass pipe line 212 is connected to the water tank 204 side to extend to a position higher than the water level so that the water contained in the water tank does not flow back to the bypass pipe side, the water tank ( 204 may be located in a refrigerating compartment in which air cooled by conventional cooling means is stored.

Another supply pipe 222 is connected to the lower side of the water tank 204, the supply pipe 222 is configured to supply water to the hot water tank (224). This hot water tank is equipped with a heater 226 of ordinary band type. The circulation system for circulation of water between the cold water cock 206 and the water tank 204 may be equally applied between the hot water tank 224 and the hot water cock 208. The cocks 206 and 208 are formed with air holes on the outlet port side to remove the water present at the outlet side of the outlet port when the opening and closing member blocks the inlet side of the outlet port.

The cold / hot water machine of the present invention configured as described above performs temperature control of water from the water tank while the normal cooling means and / or the heating means are operated. The water passing through the cooling means becomes cold water and is supplied to the cock 206 side, and the water passing through the heating means becomes hot water and is supplied to the other cock 208 side.

When the pump 214 starts to be driven in this state, the water in the water tank 204 is supplied through the supply pipe 210 and flows into the inlet port of the cock 206 via the electrolytic sterilization kit 300. At this time, when the normal opening and closing member is opened to the outlet port, the water supplied by the pump 214 is discharged to the outlet port. In addition, when the opening and closing member blocks the outlet port, the water coming out of the pump 214 enters the water tank 204 along the bypass pipe 212 while circulating to the circulation port in the small chamber. That is, the water discharged from the water tank 204 through the supply pipe 210 is returned to the water tank 204 through the bypass pipe 212 again. In this circulation process, the water is continuously circulated according to the driving of the pump 214 installed in the supply pipe 210, and the bacteria in the water circulating in this process are sterilized in the electrolytic sterilization kit 300 so that the water without bacteria It is circulated continuously. In addition, since the water supplied to the hot water tank 224 can be circulated in the same manner, water without bacteria can be supplied, but since the water supplied from the water tank is heated by the heater and the germs are sterilized, the water tank is separately provided. There is no need to install a bactericidal device.
