도 3은 제1실시예에 따른 공용정수시스템에서 살균을 위한 온수의 유동을 설명하기 위한 도면이다. 도 3이하의 도면에서 굵은 은선(hidden line)은 가열되지 않은 물이 유동하는 부분을 나타내고, 굵은 실선은 가열되어 배관을 살균하는 온수가 유동하는 부분을 나타낸다. 또한 도 3이하에서 공용정수시스템이 살균모드로 작동하는 경우 물의 유동을 나타내었다.Figure 3 is a diagram for explaining the flow of hot water for sterilization in a public water purification system according to the first embodiment. In the drawings of FIG. 3 and below, the thick hidden line represents the portion where unheated water flows, and the thick solid line represents the portion where hot water that is heated to sterilize the pipe flows. In addition, Figure 3 and below shows the flow of water when the public water purification system operates in sterilization mode.
도 3에서는 살균되는 배관전체를 도시하였다. 도 3을 참조하면, 공용정수시스템이 살균모드로 동작하는 경우, 제1배관(110)으로 유입된 물은 제1히터(210)에서 가열되어 제1배관(110) 내지 제4배관(140)을 유동하고, 제3배관(130) 또는 제4배관(140)을 통해 외부로 배출될 수 있다. 이는 후술하는 제2실시예에 대해서도 동일하게 적용될 수 있다.Figure 3 shows the entire pipe being sterilized. Referring to FIG. 3, when the public water purification system operates in sterilization mode, the water flowing into the first pipe 110 is heated in the first heater 210 and is heated in the first pipe 110 to the fourth pipe 140. flows and may be discharged to the outside through the third pipe 130 or the fourth pipe 140. This can be equally applied to the second embodiment described later.
한편, 배관의 살균은 제1히터(210)에 의해 가열된 온수를 사용하여 진행할 수 있다. 이때, 배관의 각 부분을 분리하여 살균을 진행할 수 있다. 각 배관을 분리하여 살균하는 구체적인 과정은 하기에 설명한다.Meanwhile, sterilization of pipes can be performed using hot water heated by the first heater 210. At this time, sterilization can be performed by separating each part of the pipe. The specific process of separating and sterilizing each pipe is described below.
살균모드에서 제1히터(210)가 가열되고, 상수도관으로부터 배출되는 원수는 제1히터(210)를 통과하면서 가열되어 온수가 될 수 있다. 제1실시예와 하기에 설명하는 제2실시예의 공용정수시스템에서는 온수를 생산하는 제1히터(210)에 의해 물이 가열되어 공용정수시스템의 배관, 필터(230), 냉각장치(330)를 통과하면서 이들을 살균할 수 있다.In the sterilization mode, the first heater 210 is heated, and the raw water discharged from the water pipe is heated while passing through the first heater 210 to become hot water. In the public water purification system of the first embodiment and the second embodiment described below, water is heated by the first heater 210 that produces hot water, and the piping, filter 230, and cooling device 330 of the public water purification system are heated. They can be sterilized as they pass through.
실시예에서, 살균을 위한 별도의 장치를 추가하지 않고, 음용수를 생산하는데 사용되는 제1히터(210)를 사용하여 생산된 온수를 배관과 이에 구비되는 장치의 살균에 사용할 수 있다. 따라서, 공용정수시스템의 구조를 단순화하여 제작비용을 절약하고 공용정수시스템의 전체크기를 줄일 수 있으며, 동시에 공용정수시스템 내부를 효과적으로 살균할 수 있다.In an embodiment, hot water produced using the first heater 210 used to produce drinking water can be used to sterilize pipes and devices provided therewith, without adding a separate device for sterilization. Therefore, by simplifying the structure of the public water purification system, manufacturing costs can be saved and the overall size of the public water purification system can be reduced, and at the same time, the inside of the public water purification system can be effectively sterilized.

The faucet 50 is a part where cooking water and washing water are discharged, and can be installed separately from the hot and cold module 30 in the kitchen sink 10. The seventh pipe 170 and the washing water pipe 529 may be connected to the faucet 50.
제7배관(170)은 제2배관(120)에서 필터(230)의 출구를 지난 위치에서 분기될 수 있다. 제7배관(170)을 통해 음식물을 조리하는데 사용되는 조리수가 유동할 수 있다. 조리수는 필터(230)를 지난 정수이다. 사용모드에서 물은 필터(230)를 지나 여과되어 조리수가 되고, 조리수는 제7배관(170)을 통해 유동하여 파우셋(50)으로 배출될 수 있다.The seventh pipe 170 may branch from the second pipe 120 at a position past the outlet of the filter 230. Cooking water used to cook food may flow through the seventh pipe 170. Cooking water is purified water that has passed the filter 230. In the use mode, water is filtered through the filter 230 to become cooking water, and the cooking water flows through the seventh pipe 170 and can be discharged into the faucet 50.
제7배관(170)에는 조리수밸브(522)가 배치될 수 있다. 사용자가 조리수를 사용하는 경우 조리수밸브(522)가 개방되어 필터(230)를 통과한 조리수는 제7배관(170)을 유동하여 파우셋(50)으로 배출될 수 있다.A cooking water valve 522 may be disposed in the seventh pipe 170. When a user uses cooking water, the cooking water valve 522 is opened and the cooking water that has passed through the filter 230 may flow through the seventh pipe 170 and be discharged into the faucet 50.
세척수배관(529)은 제2배관(120)으로부터 분기되고 세척수가 유동하는 배관이다. 세척수는 살균물질이 함유된 것으로, 실시예의 공용정수시스템에서는 물을 전기분해하는 과정에서 발생하는 살균물질을 함유한 전해수를 세척수로 사용할 수 있다.The washing water pipe 529 is a pipe that branches off from the second pipe 120 and through which washing water flows. Washing water contains sterilizing substances, and in the public water purification system of the embodiment, electrolyzed water containing sterilizing substances generated in the process of electrolyzing water can be used as washing water.
전해수의 생산을 위해 세척수배관(529)에는 전해수모듈(523)과 세척수밸브(524)가 배치될 수 있다. 전해수모듈(523)은 필터(230)를 통과한 물을 전기분해하여 살균물질을 포함하는 전해수를 생산할 수 있다.To produce electrolyzed water, an electrolyzed water module 523 and a washing water valve 524 may be placed in the washing water pipe 529. The electrolyzed water module 523 can produce electrolyzed water containing sterilizing substances by electrolyzing the water that has passed through the filter 230.
드레인배관(525)은 세척수배관(529)으로 분기되고 전해수모듈(523)을 통과한 물은 파우셋(50)으로 배출되지 않고, 드레인배관(525)을 유동하여 공용정수시스템 외부로 배출될 수 있다.The drain pipe 525 branches off to the washing water pipe 529, and the water that has passed through the electrolyzed water module 523 is not discharged to the faucet 50, but flows through the drain pipe 525 and can be discharged outside the public water purification system. there is.
세척수밸브(524)는 세척수배관(529)에서 드레인배관(525)이 분기되는 지점에 배치될 수 있다. 세척수밸브(524)는 삼방밸브로 구비될 수 있다. 따라서, 세척수밸브(524)의 선택에 따라 전해수모듈(523)에서 배출된 물이 계속 세척수배관(529)을 유동하여 파우셋(50)으로 배출되도록 하거나 또는 드레인배관(525)을 통해 공용정수시스템 외부로 배출되도록 할 수 있다.The washing water valve 524 may be placed at a point where the drain pipe 525 branches from the washing water pipe 529. The washing water valve 524 may be provided as a three-way valve. Therefore, depending on the selection of the washing water valve 524, the water discharged from the electrolyzed water module 523 continues to flow through the washing water pipe 529 and is discharged to the faucet 50 or through the drain pipe 525 to the public water purification system. It can be discharged to the outside.
도 6은 제2실시예에 따른 공용정수시스템에서 살균을 위한 온수의 유동을 설명하기 위한 도면이다. 제2실시예에서는 전술한 제1실시예에 따른 공용정수시스템의 배관살균에 더하여 제7배관(170)을 추가적으로 살균할 수 있다.Figure 6 is a diagram for explaining the flow of hot water for sterilization in a public water purification system according to the second embodiment. In the second embodiment, in addition to sterilizing the pipes of the public water purification system according to the first embodiment described above, the seventh pipe 170 can be additionally sterilized.
한편, 세척수배관(529)과 드레인배관(525)은 온수로 살균하지 않을 수 있다. 세척수배관(529)과 드레인배관(525)은 살균물질이 함유된 전해수가 유동하므로, 전해수에 의해 충분히 살균되므로, 별도로 온수를 이용하여 살균하지 않아도 되기 때문이다.Meanwhile, the washing water pipe 529 and the drain pipe 525 may not be sterilized with hot water. This is because electrolyzed water containing sterilizing substances flows through the washing water pipe 529 and the drain pipe 525, and is sufficiently sterilized by the electrolyzed water, so there is no need for separate sterilization using hot water.
제2실시예는 제1실시예 일부 배관이 추가된 것이므로, 배관 각 부분을 분리하여 살균하는 과정을 설명함에 있어서, 제1실시예에 대해서는 별도의 설명을 생략한다. 이는 하기에 설명하는 제2실시예의 세척과정에 대한 설명으로부터 자명하기 때문이다. 이하에서 도면을 참조하여 배관 각 부분을 분리하여 살균하는 과정을 구체적으로 설명한다.Since the second embodiment is a part of the first embodiment with some pipes added, when explaining the process of separating and sterilizing each part of the pipe, a separate description of the first embodiment will be omitted. This is because it is obvious from the description of the washing process of the second embodiment described below. Below, the process of separating and sterilizing each part of the pipe will be described in detail with reference to the drawings.
도 7 내지 도 11은 제2실시예에 따른 공용정수시스템에서 각 배관들과 장치를 살균하기 위한 온수의 유동을 설명하기 위한 도면이다. 각각의 분리된 살균과정은 특별한 순서가 없이 임의로 진행될 수 있다.Figures 7 to 11 are diagrams for explaining the flow of hot water for sterilizing each pipe and device in the public water purification system according to the second embodiment.
