진공 단열 탱크 구조는 열차단 효과가 높아 온수기 또는 급탕탱크 등에 많이 사용되어져 왔으며, 일본 특허공개공보 특개2006-105538호에 기술된 바와 같이 많은 연구개발이 이루어져 왔다.The vacuum insulated tank structure has been widely used in water heaters or hot water supply tanks due to its high thermal barrier effect, and as described in Japanese Patent Laid-Open No. 2006-105538, many research and developments have been made.

도 1은 종래의 일본 특허공개공보 특개2006-105538호의 대표도이다.1 is a representative view of Japanese Patent Laid-Open No. 2006-105538.

종래 온수기의 진공 단열 탱크의 몸체(1)는 내통(11)과 외통(12)으로 이루어진 2중 구조부와 2중 구조부의 하부에 형성된 개구부에는 1 중 구조부(1b)가 설치된다. 또한, 1 중 구조부(1b)에는 내통(11)의 내부공간으로 돌출되도록 히터(4)가 설치되며, 냉수 유입관(2) 및 온수 유출관(3)이 관통되도록 설치된다. 이때, 냉수 유입관(2)은 수도관에 직결되어 사용되고, 냉수 유입관(2)에 의하여 배출된 물이 히터(4)에 의하여 가열이 용이하도록 히터(4)에 인접되는 다수의 배출공이 형성되어 있다. 또한 온수 유출관(3)에 물이 유입되는 관입구는 내통(11)의 상면에 인접되어 있어 내통(11)의 내부에서 발생되는 가스가 유입구에 흡입되어 외부로 배출되는 구조를 이루고 있다.The body 1 of the vacuum insulated tank of the conventional water heater is provided with a double structure 1b having a double structure formed of an inner cylinder 11 and an outer cylinder 12 and an opening formed under the double structure. In addition, the heater 4 is installed in the structure 1b so as to protrude into the inner space of the inner cylinder 11, and the cold water inlet pipe 2 and the hot water outlet pipe 3 are installed therethrough. At this time, the cold water inlet pipe 2 is used directly connected to the water pipe, a plurality of discharge holes adjacent to the heater 4 is formed so that the water discharged by the cold water inlet pipe 2 is easily heated by the heater (4) have. In addition, the inlet for the water flowing into the hot water outlet pipe 3 is adjacent to the upper surface of the inner cylinder 11 has a structure in which gas generated in the interior of the inner cylinder 11 is sucked into the inlet and discharged to the outside.

이러한 구조의 온수기는 냉수 유입관(2)에 수도관이 직결되어 있어 수도관 단말의 수압에 의하여 단열 탱크 내에 물이 유입된 후 히터(4)에 의하여 가열되면서 저장공간의 상부에 설치되는 온수 유출관(3)의 관입구로 가열된 물과 함께 가스가 유입되어 배출된다. 따라서 냉수 유입관(2)에 유입되는 물은 강제적으로 저장용기에 저장된 물의 수압과 가스압을 극복할 수 있는 수압이 필요하게 되고, 수도관 단말로부터 이러한 수압을 얻지 못하게 되는 경우에는 냉수 유입관(2)으로 물이 유입될 수 없으며, 온수 유출관(3)으로 온수가 배출될 수 없다. The water heater of this structure is directly connected to the cold water inlet pipe (2) is a hot water outlet pipe installed in the upper portion of the storage space is heated by the heater (4) after the water is introduced into the insulating tank by the water pressure of the water pipe terminal ( Gas is introduced and discharged together with the water heated through the inlet of 3). Therefore, the water flowing into the cold water inlet pipe (2) forcibly requires a water pressure to overcome the water pressure and gas pressure of the water stored in the storage container, when the cold water inlet pipe (2) is not obtained from the water pipe terminal No water can be introduced into the hot water, and hot water cannot be discharged into the hot water outlet pipe 3.

이와 같은 구조의 강제적인 순환구조의 온수기는 외부로부터 수압이 제공되지 않는 자연 유하식의 냉온수기 및 커피 자판기 등에 사용되는 온수 시스템에는 탱크 내에 저장된 물의 수압과 가열시에 발생되는 가스압을 극복할 수 없어 사용될 수 없다. The forced circulation water heater of such a structure cannot be used in a hot water system used for a natural cold / hot water machine or a coffee vending machine that does not provide water pressure from the outside, and cannot overcome the water pressure of the water stored in the tank and the gas pressure generated during heating.

도 2는 본 발명의 일실시예를 설명하기 위한 단면도이다.2 is a cross-sectional view for explaining an embodiment of the present invention.

도 2에 도시된 실시예의 온수기(100)는 온수탱크(110)와 온수탱크(110)에 설치된 부속설비들로 이루어진다. 온수탱크(110)의 상부에 저장조(300)가 설치되고, 저장조(300)와 온수탱크(110)는 온수용 유입관(101)으로 연결되어 저장조(300)로부터 온수탱크(110)로 물이 자연유하식으로 공급된다. 또한 온수기(100)와 병행으로 냉수기(200)가 설치되며, 냉수기(200)의 냉수탱크(210)는 저장조(300)와 냉수용 유입관(201)으로 연결되어 냉수탱크(210)에 물이 공급되게 된다.Water heater 100 of the embodiment shown in Figure 2 consists of a hot water tank 110 and the accessory equipment installed in the hot water tank (110). Storage tank 300 is installed on the upper portion of the hot water tank 110, the storage tank 300 and the hot water tank 110 is connected to the inlet pipe 101 for hot water, the water from the storage tank 300 to the hot water tank 110 Supplied naturally. In addition, the cold water heater 200 is installed in parallel with the water heater 100, the cold water tank 210 of the cold water heater 200 is connected to the storage tank 300 and the cold water inlet pipe 201 to the cold water tank 210 Water will be supplied.

온수기(100)의 온수 탱크(110)는 단열하기 위하여 벽과 벽사이가 진공된 2중 구조의 몸체(102)와 몸체(102) 하부에 형성된 개구부에 탈부착되는 1중 구조의 헤드(103)로 이루어지며, 헤드(103)에는 온수 탱크 내부에 저장된 물을 가열하는 히터(104)와, 헤드(103)에 관통하여 설치되는 온수용 유입관(101), 온수용 유출 관(105), 온수 탱크 내부의 온도를 감지하는 온도 감지 센서(106)와, 온수 탱크 내부의 물을 퇴수하기 위한 퇴수관(107)이 설치된다.The hot water tank 110 of the water heater 100 is a double structure body 102 is vacuumed between the wall and the wall to insulate and the head 103 of the double structure detachable to the opening formed in the lower portion of the body 102 The head 103 has a heater 104 for heating the water stored in the hot water tank, an inlet pipe 101 for hot water installed through the head 103, an outlet pipe 105 for hot water, and a hot water tank. A temperature sensor 106 for sensing the temperature inside and a discharge pipe 107 for discharging the water inside the hot water tank are installed.

온수기(100)에서 90℃ 이상으로 물을 가열하고, 가열된 물은 20℃ 정도의 상온과 많은 온도 차이를 갖고 있기 때문에 온수탱크(110)로부터 많은 열이 외부로 방출되게 되므로 온수용 유입관(101), 온수용 유출관(105)은 온수탱크(110)의 하부에 설치된 헤드(103)를 관통하도록 설치함으로써 관을 통하여 외부로 유출되는 열을 최소화하도록 한다.Since the water is heated at 90 ° C. or higher in the water heater 100, and the heated water has a large temperature difference with about 20 ° C., a lot of heat is discharged from the hot water tank 110 to the outside so that the hot water inlet pipe ( 101, the hot water outlet tube 105 is installed to penetrate the head 103 installed in the lower portion of the hot water tank 110 to minimize the heat flowing out through the tube.

온수용 유출관(105)은 대략 U자 형상으로 이루어져 헤드(102)를 관통하여 관입구(105')는 온수탱크(110) 내에 위치하게 되고, 관출구는 온수 탱크(110)의 외부에 위치하게 되고, 관출구에는 온수 토출밸브(108)가 설치되고, 온수 토출밸브(108)의 높이는 후술되는 냉수 토출밸브(208)와 같은 높이로 설치되어 사용자가 편리하게 사용할 수 있도록 한다.The hot water outlet pipe 105 is formed in a substantially U shape and penetrates the head 102 so that the inlet 105 'is positioned in the hot water tank 110, and the outlet is located outside the hot water tank 110. The hot water discharge valve 108 is installed at the pipe outlet, and the height of the hot water discharge valve 108 is installed at the same height as the cold water discharge valve 208 to be described later, so that the user can conveniently use it.

온수용 유입관(101) 또한 대략 U자 형상으로 이루어지며 헤드(102)를 관통하고, 관입구는 저장조(300)에 연결되고, 관출구(101')는 온수탱크(110) 내에 위치하게 된다.Hot water inlet pipe 101 also has a substantially U-shape and penetrates the head 102, the inlet is connected to the reservoir 300, the outlet 101 'is located in the hot water tank 110 .

이때 온수용 유입관(101)의 관출구(101')의 높이는 항상 온수용 유출관(105)의 관입구(105')의 높이보다 높게 설치되도록 한다. 온수 토출밸브(108)가 잠겨져 물이 배출되지 않은 상황에서는 온수 탱크(110)의 물은 가열된 상태이기 때문에 온수 탱크(110)내에는 일정량의 가스를 내포되어 있어 가압되게 되어 온수 탱크(110) 전체에 물이 저장되지 않고, 지시선(109)과 같이 온수용 유입관(101)의 관출 구(101')와 온수용 유출관(105)의 관입구(105') 사이의 높이를 유지하게 된다. 또한, 가열에 의하여 더 많은 양의 가스가 발생되어 탱크 내의 압력이 높아지는 경우에는 가스는 저장조(300)와 온수 탱크의 높이 차이에 의하여 발생되는 수압을 극복하고 저장조(300)로 배출되게 된다.At this time, the height of the inlet 101 'of the hot water inlet pipe 101 is always higher than the height of the inlet 105' of the hot water outlet tube 105. In a situation where the hot water discharge valve 108 is locked and no water is discharged, since the water in the hot water tank 110 is heated, a predetermined amount of gas is contained in the hot water tank 110 to pressurize the hot water tank 110. Water is not stored in the whole, and maintains the height between the inlet 101 'of the hot water inlet pipe 101 and the inlet 105' of the hot water outlet tube 105 like the leader line 109. . In addition, when a larger amount of gas is generated by heating and the pressure in the tank is increased, the gas is discharged to the storage tank 300 while overcoming the water pressure generated by the height difference between the storage tank 300 and the hot water tank.

만일 온수용 유입관(101)의 관출구(101')가 온수용 유출관(105)의 관입구(105') 보다 낮게 되면, 온수 탱크(110) 내의 발생가스는 온수용 유출관(105)의 관입구(105')에 유입된 후 온수 토출밸브(108)를 통하여 외부로 배출되어야 하기 때문에 사용자가 온수 토출밸브(108)를 열게 되면 온수가 배출되지 않고 한동안 기체만이 배출되게 되어 사용상 매우 불편하게 된다.If the outlet 101 'of the hot water inlet pipe 101 is lower than the inlet 105' of the hot water outlet tube 105, the generated gas in the hot water tank 110 is the hot water outlet tube 105. Since the user should open the hot water discharge valve 108 after entering the inlet 105 'of the hot water discharge valve 108, when the user opens the hot water discharge valve 108, only the gas is discharged for a while and the gas is discharged for a very long time. It becomes uncomfortable.

또한, 온수용 유출관(105)의 높이가 가장 부분에는 퇴수관(107)에 연결된 연결관(111)이 연결되어 퇴수관(107)의 단부에 설치된 퇴수밸브(112)를 열개되면 온수 탱크(110) 내에 저장된 물 뿐만 아니라 온수용 유출관(105)내의 물도 함께 배출되도록 한다.In addition, the height of the hot water outlet pipe 105 is connected to the connection pipe 111 connected to the discharge pipe 107 at the most part to open the discharge valve 112 installed at the end of the discharge pipe 107 hot water tank ( Not only the water stored in the 110, but also the water in the outlet pipe 105 for hot water is discharged together.

냉수탱크(210)는 단열 진공방식의 2중 구조의 몸체(202) 몸체(202)의 상부 중심에 형성된 개구부에 착탈되는 헤드(203)로 이루어진다. 또한, 헤드(203)에는 냉수탱크(210)에 저장된 물을 냉각시키는 증발기(204)가 설치되며,냉수용 유입관(201)과 냉수용 유출관(205)이 관통되어 설치되고, 냉수탱크(210)의 내부의 온도를 측정하는 온도 센서(206)가 설치된다. 냉수용 유출관(201)의 관출구에는 냉수 토출밸브(208)가 설치된다.Cold water tank 210 is composed of a head 203 detachable to the opening formed in the upper center of the body 202, the body 202 of the dual structure of the adiabatic vacuum system. In addition, the head 203 is provided with an evaporator 204 for cooling the water stored in the cold water tank 210, the cold water inlet pipe 201 and the cold water outlet pipe 205 is installed through the cold water tank ( A temperature sensor 206 for measuring the temperature inside the 210 is installed. A cold water discharge valve 208 is installed at the outlet of the cold water outlet pipe 201.

이때, 냉수기(200)에서 냉수탱크(210)의 상부에 헤드를 설치하고, 냉수용 유 입관(201), 냉수용 유출관(205)이 헤드를 관통하도록 설치하는 이유는 냉각된 물은 상향으로 열전달이 잘 발생되지 않기 때문에 냉각효율을 높이도록 하기 위한 것이다.At this time, the head is installed on the upper portion of the cold water tank 210 in the cold water tank 200, the cold water inlet pipe 201, the cold water outlet pipe 205 is installed to penetrate the head is the cooled water is upward This is to increase the cooling efficiency because heat transfer is not generated well.
