Description

온수보일러의 순환장치{CIRCULATOR FOR FLOOR-HEATING BOILER}Hot water boiler circulator {CIRCULATOR FOR FLOOR-HEATING BOILER}

본 발명은 온수 보일러의 순환장치에 관한 것이다.The present invention relates to a circulation system of a hot water boiler.

일반적인 온수보일러는 온수의 가열 수조와 버너 또는 히터로 구성되고 가열된 온수는 별도의 순환펌프에 의하여 방열관으로 순환하는 장치로 구성되어 있다.The general hot water boiler is composed of a hot water heating tank and a burner or a heater, and the heated hot water is composed of a device that circulates into a heat dissipation pipe by a separate circulation pump.

대형 온수보일러의 경우에는 순환펌프가 공급관의 중간부에 설치되어 있어도 보일러실과 주거 실내와는 격리되어 있기 때문에 펌프의 가동에 따른 기계적 소음의 문제는 비교적 적다.In the case of a large hot water boiler, even if the circulation pump is installed in the middle of the supply pipe, it is isolated from the boiler room and the dwelling room, so the mechanical noise caused by the operation of the pump is relatively small.

그러나 침대단위의 작은 면적의 온수 난방에 있어서는 소형보일러와 순환 펌프가 침대나 실내에 근접 설치되기 때문에 야간에는 소음의 장해가 매우 크다.However, in the hot water heating of a small bed unit, noise disturbance is very large at night because a small boiler and a circulation pump are installed close to the bed or the room.

더욱이 소형 보일러의 경우에는 가열매체의 용량이 크지 않어, 열매체의 가열과 순환작동이 지속되어야만 방열관의 온도를 유효하게 유지할 수 있기 때문에 순환펌프의 가동소음이 지속되므로서 소음의 수면방해 등의 피해가 더욱 크다.In addition, in the case of small boilers, the heating medium does not have a large capacity, and only when heating and circulation operation of the heating medium is continued to maintain the temperature of the heat dissipation pipe effectively. Is even larger.

본 발명의 목적은 소형 온수 보일러에 있어서, 보일러와 순환펌프의 복합기능을 가지면서 구조가 간단하여 취급이 용이하고 조용하고 강력한 힘으로 열매체를 지속적으로 순환시키어 유효하게 난방을 유지할 수 있게 한 온수보일러의 순환장치를 제공하려는데 있다.An object of the present invention is a small hot water boiler, a hot water boiler that has a complex function of the boiler and the circulation pump, the structure is simple, easy to handle, and continuously circulating the heat medium with a quiet and powerful force to effectively maintain the heating To provide a circulatory system.

본 발명은 열매체의 가열수단과 순환수단이 복합구조로 하여 열매체를 가열하는 기능과 가열된 열매체의 순환의 복합기능을 가진다.According to the present invention, the heating means and the circulation means of the heat medium have a complex function of heating the heat medium and the circulation function of the heated heat medium.

즉 보일러동체가 펌프의 동체이며 동체 내부에 열매체를 가열하는 히터와 가열된 열매체를 순환시키는 피스톤이 함께 구비되어 있다. 따라서 보일러와 펌프가단일체이다.That is, the boiler body is the body of the pump, and a heater for heating the heat medium and a piston for circulating the heated heat medium are provided together inside the body. Thus, the boiler and pump are unitary.

보일러 동체를 겸한 펌프동체에는 파워실린더가 결합되어 있고 파워 피스톤은 순환수단인 펌프의 피스톤과 연결되어 있다.The pump body, which also serves as the boiler body, is combined with a power cylinder and the power piston is connected with the piston of the pump, which is a circulation means.

파워 실린더는 통상의 팽창물질이 밀봉된 액튜에이터와 연관되어 있다.The power cylinder is associated with an actuator sealed with a conventional expandable material.

액튜에이터는 공지한 팽창물질이 밀봉된 소형탱크로서 팽창물질을 가열하여 팽창시키는 히터와 팽창물질을 냉각수축시키는 반도체인 냉각소재가 구비되어 있다.The actuator is a small tank in which a known expansion material is sealed and includes a heater that heats and expands the expansion material and a cooling material that is a semiconductor that contracts and expands the expansion material.

따라서 전자제어기의 프로그램에 따라 액튜에이터에서 히터와 냉각소자가 교호로 일정한 주기로 작동하여 팽창물질의 팽창 및 수축을 반복한다.Therefore, according to the program of the electronic controller, in the actuator, the heater and the cooling element alternately operate at regular intervals to repeat expansion and contraction of the expansion material.

이러한 팽창물질의 팽창 압력에 의하여 파워 피스톤이 작동되면서 펌프 피스톤을 구동시키어 보일러에서 가열된 열매체는 지속적으로 공급관을 통하여 방열관으로 순환공급하여 난방한다.The power piston is operated by the expansion pressure of the expansion material to drive the pump piston, and the heating medium heated in the boiler is continuously circulated and supplied to the heat radiating pipe through the supply pipe to be heated.

방열관으로 공급된 열매체는 보일러에 순환되어서 가열되며 반복적인 순환으로 난방용 방열관에서 유효하게 난방을 유지하게 된다.The heat medium supplied to the heat dissipation tube is circulated in the boiler and heated, and the heating medium is effectively maintained in the heat dissipating tube by repeated circulation.

본 발명에서 가열매체의 순환수단은 액튜에이터에 의하여 구동되는 파워 피스톤에 의하여 펌프 피스톤이 느린 주기로 펌핑작용을 하기 때문에 고속회전하는 원심펌프와 같은 소음이 없다.In the present invention, the circulation means of the heating medium has no noise, such as a centrifugal pump that rotates at high speed because the pump piston is pumped at a slow cycle by a power piston driven by an actuator.

또 팽창물질의 팽창력으로 구동력이 발생되기 때문에 힘이 강력하여 가늘고 긴 난방용 방열관으로 열매체가 원활하게 순환될 수 있다. 열매체의 원활한 순환으로 방열관의 온도는 높게 유지된다.In addition, since the driving force is generated due to the expansion force of the expansion material, the heat medium can be smoothly circulated to the thin and long heat radiating tube for heating. The temperature of the heat dissipation tube is kept high by the smooth circulation of the heat medium.

펌프와 보일러가 동일체이므로 구조가 그만큼 간단하고 기계적 마찰부분이 고장날만한 부분이 거의 없다.Since the pump and the boiler are the same, the structure is so simple and there are few parts where the mechanical friction part can fail.

따라서 종래의 소형 보일러에 비하여 취급이 간편하고 조용하게 따뜻한 난방을 할 수 있다.Therefore, the heating is simpler and quieter than the conventional small boiler.

열매체의 가열수단인 보일러 동체(1)는 가열된 열매체의 순환수단인 펌프의 동체를 겸한다. 상기 동체(1)의 내부에는 열매체를 가열하는 전열히터(2)와 가열된 열매체를 순환시키는 밸브(3v)를 가진 피스톤(3)이 상호 간섭되지 않는 조건으로 구비되어 하나의 구성체를 이룬다.The boiler body 1 which is a heating means of a heat medium serves as a body of a pump which is a circulation means of a heated heat medium. Inside the fuselage 1, a heat transfer heater 2 for heating the heat medium and a piston 3 having a valve 3v for circulating the heated heat medium are provided under conditions such that they do not interfere with each other to form a structure.

동체(1)의 선단 유출구(1a)에는 일방향 밸브(1v)를 통하여 방열관 (6)으로 연결된 공급관(1p)이 관접되고 방열관(6)에 연결된 환수관(1p')은 펌프 피스톤(3)의 뒷쪽 동체(1)의 환수구(1b)에 일방향 밸브(1v')와 함께 연결되어 가열매체가 일방향으로 순환된다.The supply pipe 1p connected to the heat dissipation pipe 6 through the one-way valve 1v is connected to the front outlet 1a of the body 1, and the return pipe 1p 'connected to the heat dissipation pipe 6 is connected to the pump piston 3. The heating medium is circulated in one direction by being connected with the one-way valve 1v 'to the return port 1b of the rear fuselage 1.

펌프기능을 갖는 동체(1)의 일단부측에는 내경이 작은 파워 실린더(4)가 결합되고 그 내부에 설치된 파워 피스톤(4a)은 상기 펌프의 피스톤(3)과 로드(4b) 및스프링(4s)에 의하여 일체로 연결되어 있다.A power cylinder 4 having a small inner diameter is coupled to one end of the body 1 having a pump function, and a power piston 4a installed therein is provided with a piston 3, a rod 4b, and a spring 4s of the pump. It is connected integrally by.

상기 파워실린더(4)의 선단부측에 통기공(4c)이 형성되어 파워 피스톤 (4a)의 전후 동작시의 실린더 내부의 진공상태가 해소된다.A vent hole 4c is formed on the tip end side of the power cylinder 4, and the vacuum inside the cylinder during the forward and backward operation of the power piston 4a is eliminated.

따라서 펌프 피스톤(3)은 파워 피스톤(4a)에 의하여 구동되어 가열매체인 온수(w)를 순환시킨다.Therefore, the pump piston 3 is driven by the power piston 4a to circulate the hot water w, which is a heating medium.

상기 파워 피스톤(4)은 액튜에이터(5)에 도관(4d)으로 연결되어 있다. 액튜에이터는 공지의 팽창물질(EM)이 밀봉된 일정한 용적을 가진 탱크이다.The power piston 4 is connected to the actuator 5 by a conduit 4d. The actuator is a tank having a constant volume sealed with a known expandable material (EM).

액튜에이터(5)의 내부에는 팽창물질을 가열하는 전열히터(5h)와 팽창물질을 냉각하는 반도체인 냉각소자(5c)가 구비되어 있고 이들은 외부의 전자 제어기(CB)에 의하여 프로그램에 따라 교호의 일정한 주기로 가열 및 냉각을 반복하여 물질의팽창과 수축작용으로 파워 피스톤(4a)을 작동하게 되어 있다.The inside of the actuator 5 is provided with a heat transfer heater 5h for heating the expansion material and a cooling element 5c, which is a semiconductor for cooling the expansion material, which are alternately fixed according to a program by an external electronic controller CB. The power piston 4a is operated by the expansion and contraction action of the material by repeating heating and cooling in cycles.

본 발명은 도면에 의하여 설명되어 있으나 이 분야의 기술을 가진자가 본 발명으로 부터 극히 용이하게 실시할 수 있는 설계적인 구조의 변경이나 위치변경등은 본 발명의 특허청구의 범위에 속하는 것으로 부언한다.Although the present invention has been described with reference to the drawings, changes in the design structure or position, etc., which can be easily carried out by those skilled in the art, are included within the scope of the claims of the present invention.

본 발명의 방법과 장치에 따른 작용은 다음과 같다.The operation according to the method and apparatus of the present invention is as follows.

도 1에서 펌프 피스톤(3)이 후퇴한 위치에서 동체(1) 내부의 열매체인 온수(w)는 히터(2)에 공급되는 전기 에너지에 의하여 설정된 온도로 가열된다.In FIG. 1, in the position where the pump piston 3 is retracted, hot water w, which is a heat medium inside the body 1, is heated to a temperature set by electric energy supplied to the heater 2.

가열온도는 30-60℃범위이고 온도는 가변하여 선택적으로 조절될 수 있다. 한편 액튜에이터(5)의 히터(5h)가 전자제어기(CB)의 프로그램에 따라 일정한 시간동안 설정된 온도로 가열되면서 팽창물질은 팽창된다.The heating temperature is in the range of 30-60 ° C. and the temperature can be varied and optionally adjusted. Meanwhile, as the heater 5h of the actuator 5 is heated to a set temperature for a predetermined time according to the program of the electronic controller CB, the expanded material is expanded.

가열온도는 팽창물질에 따라 다르나 일반적으로 60- 80℃이다.The heating temperature depends on the expansion material but is generally 60-80 ° C.

이때 액튜에이터(5)에서의 팽창압력이 파워 피스톤(4a)에 작용되고 파워 피스톤(4a)에 의하여 펌프피스톤(3)이 전진되면서 동체(1)의 가열매체인 온수(w)를 유출구(1a)를 거쳐 공급관(1p을 통하여 방열관(6)으로 공급시키는 동시 방열관(6)에 담긴 냉각된 온수는 환수관(1p')을 통하여 환수구(1b)로 환수된다.At this time, the expansion pressure in the actuator (5) acts on the power piston (4a) and the pump piston (3) is advanced by the power piston (4a), the hot water (w) which is the heating medium of the body (1) to the outlet (1a) The cooled hot water contained in the simultaneous heat dissipation tube 6 which is supplied to the heat dissipation tube 6 through the supply pipe 1p is returned to the return port 1b through the return tube 1p '.

한편 도2 에 표시된 바와 같이, 액튜에이터(5)의 히터(5h)는 전자적으로 전원 공급이 차단되는 동시 냉각소자(5c)에 공급되어 가열된 팽창물질(EM)을 신속하게 인위적으로 냉각시킨다.On the other hand, as shown in Fig. 2, the heater 5h of the actuator 5 is supplied to the simultaneous cooling element 5c in which the power supply is cut off electronically to quickly and artificially cool the heated expanded material EM.

냉각소자는 공지된 것으로 본 발명에서는 냉각소자를 채용하여 팽창물질을 신속하게 냉가하므로써 액튜에이터의 싸이클 주기를 단축할 수 있게 하였다.The cooling device is known and in the present invention, by employing the cooling device to quickly cool the expansion material it is possible to shorten the cycle cycle of the actuator.

액튜에이터(5)의 열팽창물질(EM)이 수축되면 파워 피스톤(4a)은 복귀스프링(4s)에 의하여 원위치로 복귀된다. 상기 파워 피스톤(4a)의 복귀동작에 따라 전진된 펌프 피스톤(3)이 복귀되며 피스톤(3)의 복귀시에는 밸브(3v)가 개방되므로 동 피스톤(3)의 후방측의 온수가 밸브(3v)를 통하여 피스톤의 앞쪽으로 이동된다.When the thermal expansion material EM of the actuator 5 contracts, the power piston 4a is returned to its original position by the return spring 4s. The pump piston 3 advanced according to the return operation of the power piston 4a is returned, and upon return of the piston 3, the valve 3v is opened, so that the hot water at the rear side of the piston 3 is opened by the valve 3v. To the front of the piston.

이로써 펌프 피스톤(3)은 일행정을 마치며 이 같은 동작이 반복하여 가열된온수는 지속적으로 순환된다.As a result, the pump piston 3 finishes one stroke, and the heated water is repeatedly circulated through such an operation.

본 발명에서 펌프 피스톤의 왕복주기는 5-10회/분 정도로서 느리며 그러나 가열온도가 30-60℃범위로 높고 순환 길이가 길지 않기 때문에 방열관(6)에서 냉각온도가 현저하게 냉강되기 전에 순환되므로 유효한 난방유지가 가능하다.In the present invention, the reciprocating cycle of the pump piston is slow as about 5-10 times / minute, but since the heating temperature is high in the range of 30-60 ° C. and the circulation length is not long, it is circulated before the cooling temperature is significantly coldened in the heat dissipating pipe 6. Effective heating can be maintained.

또 액튜에이터는 설계적으로 동체에 결합형태로 설치되기 때문에 외부 구조가 간단하고 단순하며 한번 설치후에는 거의 점검할 부분이 없고 전자 프로그램의 설정에 따라 소정의 주기로 액튜에이터의 작용으로 파워 피스톤 및 펌프 피스톤의 연동에 의하여 온수가 순환되므로 기계적 마찰소음이 없이 조용하여 침대에 인접된위치에 설치 사용하기에 적합하다.In addition, since the actuator is designed to be connected to the fuselage by design, the external structure is simple and simple. After installation, there is almost no part to check and the power piston and pump piston Since hot water is circulated by interlocking, it is suitable to be installed in the position adjacent to the bed quietly without mechanical friction noise.

본 발명은 순환수단과 가열수단이 단일체로 구성되고 액튜에이터의 작동으로 파워피스톤이 작동되어 순환수단의 피스톤이 구동되게 구성되어 있기 때문에 구조가 간단하여 설치 및 취급이 간편하고 가열매체의 순환시의 펌프의 기계적 마찰 소음이 없어 소음공해가 없으며 침대의 작은 단위면적의 난방에 있어서 방열관의 내경이 작은 경우라도 강력한 힘으로 원활하게 열매체가 순환되어 따뜻한 난방을 유효하게 유지할 수 있는 효과가 있다.According to the present invention, since the circulation means and the heating means are composed of a single body, and the piston of the circulation means is driven by the power piston being operated by the operation of the actuator, the structure is simple and easy to install and handle. There is no mechanical friction noise, so there is no noise pollution. In the heating of the small unit area of the bed, even if the inner diameter of the heat dissipation tube is small, the heating medium is circulated smoothly with strong force, thereby effectively maintaining warm heating.
