다용도 온수 순환장치{Multipurpose hot water circulating apparatus}Multipurpose hot water circulating apparatus

본 고안은 침구용 매트, 침대의 난방, 의료기, 주택의 보조 난방, 혹한기의 방한 의류등에 적용하여 전자파의 영향에 방행를 받지 않으면서 절전 및 안전에 유용한 다용도 온수 순환장치에 관한 것이다.The present invention is applied to bed mats, bed heating, medical devices, auxiliary heating of homes, cold weather clothing, etc., and relates to a multipurpose hot water circulation device useful for power saving and safety without being affected by electromagnetic waves.

종래 자연 순환 보일러의 경우 급수탱크가 외부에 개방된 상태로 구비되어 있기 때문에 항시 급수탱크내의 순환수가 증발되어 순환수의 량이 감소하게 된다.In the conventional natural circulation boiler, since the water supply tank is provided in an open state to the outside, the circulation water in the water supply tank is always evaporated, thereby reducing the amount of circulation water.

이때, 순화수의 량이 감소하므로서 온수의 순환이 이루어지지 않게 되어 순환 보일러의 기능을 수행할 수 없게 되고, 상기 급수탱크내의 순환수가 증발되어 수위가 낮아지면 자동적으로 급수탱크내에 순환수를 보충하게 된다.At this time, since the amount of purified water is reduced, the circulation of hot water is not made, and thus the function of the circulating boiler cannot be performed, and when the water level is lowered due to evaporation of the circulating water in the water supply tank, the water is automatically replenished in the water supply tank. .

그리고, 겨울철 등과 같이 외부의 온도가 낮을 경우 온수의 순환을 장시간 정지시켜 두면 순환경로내에서 순환수가 동결될 우려가 있으며, 상기 순환 보일러는 부피가 크면서 무게가 무겁기 때문에 이동시킬 수 없고 어느 한 곳에 고정시켜야만 하는 단점이 있다.In addition, when the outside temperature is low, such as in winter, if the circulation of hot water is stopped for a long time, the circulation water may freeze in the circulation path, and the circulation boiler cannot move because it is bulky and heavy. There is a disadvantage that must be fixed.

본 고안은 이와 같은 종래의 문제점을 해결하기 위하여 순환수의 온도를 사용자의 임의로 설정시키고 순환수를 저장하는 저장통을 밀폐시켜 장시간 사용에 의한 순환수의 증발을 방지하여 순환수의 보충이 불필요하도록 하므로서 소음발생을 극소화하고, 제품의 크기를 콤팩트화하여 휴대 및 이동이 편리하도록 한 것으로, 첨부된 도면에 의하여 본 고안의 구성 및 작용효과를 설명하면 다음과 같다.In order to solve the conventional problems, the present invention arbitrarily sets the temperature of the circulating water and seals the storage container for storing the circulating water, thereby preventing evaporation of the circulating water by long-term use, thereby making it unnecessary to replenish the circulating water. Minimized noise generation and compact size of the product to make it convenient to carry and move, the configuration and operation of the present invention by the accompanying drawings as follows.

When the circulation water in the heating tube 1 reaches a predetermined temperature, the first check valve 6 opens and closes so that the circulation water is discharged to the circulation hose 7, and the circulation discharged by opening and closing the first check valve 6. Through a circulation hose 7 for circulating water to dissipate heat, and the circulation hose 7 A circulating water reservoir 8 which performs a contraction operation so that the circulated circulating water is introduced and stored therein, and a circulating water reservoir 8 into the hot water heater 1 in a vacuum state when all the circulating water in the hot water heater 1 is discharged. It consists of a second check valve (9) that is opened and closed to enter the circulating water stored in the), reference numeral 10 is a mat portion in which the circulation hose is disposed.

이와 같이 구성된 본 고안의 작용효과는 도 1과 도 2를 참고로 하여 설명하면 다음과 같다.The operation and effect of the present invention configured as described above will be described with reference to FIGS. 1 and 2.

사용자가 온수 순환기를 동작시켜 온수가 일정온도가 되도록 온도 조절기(4)를 사용자의 임의로 조작시 전원부(3)에서 공급된 전원에 의해 온수 가열통(1)내의 히터(2)에서 열이 발산된다.When the user operates the hot water circulator so that the hot water is at a constant temperature, heat is emitted from the heater 2 in the hot water heater 1 by the power supplied from the power supply unit 3 when the user arbitrarily operates the temperature controller 4. .

이때, 온수 가열통(1)내의 순환수가 히터(2)의 열 발산에 의해 가열되어 일정온도가 되었으면 온도상승에 의한 온수 가열통(1)의 압력 팽창에 의해 제 1체크밸브(6)가 개폐되면서 상기 제 1체크밸브(6)에 연결된 순환호스(7)로 가열된 순환수가 배출되면서 매트부(10)에 배치된 상기 순환호스(7)로 순환된후 수축작용을 수행하는 순환수 저장통(8)으로 유입된다.At this time, when the circulating water in the hot water heater 1 is heated by heat dissipation of the heater 2 and reaches a constant temperature, the first check valve 6 is opened and closed by pressure expansion of the hot water heater 1 due to the temperature rise. While the circulating water heated by the circulation hose (7) connected to the first check valve (6) while being circulated to the circulation hose (7) disposed on the mat portion 10 to perform a contraction action ( 8) flows into.

상기 순환수 저장통(8)내에는 진공상태에서 일정량(약 2/3)의 순환수가 저장되어 있어 순환호스(7)를 통해 순환된 순환수가 유입될 때 정상상태로 팽창된다.The circulation water reservoir 8 is stored in a certain amount (about 2/3) of the circulation water in a vacuum state is expanded to the normal state when the circulation water circulated through the circulation hose (7) is introduced.

한편, 온수 가열통(1)내의 순환수가 제 1체크밸브(6)의 개폐에 의해 순환호스(7)로 순환수가 유입될 때 진공상태가 되는 바, 이때 온수 가열통(1)과 순환수 저장통(8)사이에 위치한 제 2체크밸브(9)가 개폐되면서 순환수 저장통(8)에 유입된 순환수가 진공상태인 온수 가열통(1)의 내부로 유입되면서 상기 순환수 저장통(8)은 다시 수축상태가 된다.On the other hand, when the circulating water in the hot water heater (1) is introduced into the circulation hose 7 by opening and closing the first check valve (6) is a vacuum state, at this time the hot water heater (1) and the circulation water reservoir While the second check valve 9 located between the openings 8 is opened and closed, the circulating water introduced into the circulating water reservoir 8 is introduced into the hot water heating vessel 1 in a vacuum state, and the circulating water reservoir 8 is again. It is in a contracted state.

이와 같이, 온수 가열통(1)내의 순환수가 가열되어 열 팽창에 의해 제 1체크밸브(6)가 개폐되면서 순환호스(7)로 가열된 순환수가 유입되어 매트부(11)로 순환되고, 상기 순환된 순환수가 다시 수축작용을 하는 순환수 저장통(8)에 저장된후 진공상태인 온수 가열통(1)으로 저장된 순환수가 유입되도록 제 2체크밸브(9)가 개폐되므로서 히터(2)에 의해 가열된 순환수가 연속적으로 순환이 이루어진다.As such, the circulating water in the hot water heating tube 1 is heated to open and close the first check valve 6 by thermal expansion, and the circulated water heated to the circulation hose 7 is introduced and circulated to the mat part 11. The second check valve 9 is opened and closed so that the circulated circulated water is stored in the circulating water storage container 8 which contracts again, and then the circulated water stored in the hot water heating container 1 in a vacuum state is opened and closed by the heater 2. The heated circulating water is circulated continuously.

상기 온수 가열통(1)내의 순환수가 히터(2)의 열발산에 의해 가열되어 연속적으로 순환될 때 가열된 순환수가 온도 조절기(4)에 의해 조절된 온도를 초과할 경우 온수 저장통(1)의 일측에 부착된 과열 방지스위치(5)는 자동으로 온/오프작동하여 온도 조절기(4)에 의해 조절된 온도에 맞게 순환수가 가열되도록 전원공급을 제어하게 된다.When the circulated water in the hot water heating tank 1 is heated by heat dissipation of the heater 2 and continuously circulated, when the heated circulating water exceeds the temperature controlled by the temperature controller 4, the hot water storage tank 1 The overheat prevention switch 5 attached to one side is automatically turned on / off to control the power supply to heat the circulating water according to the temperature controlled by the temperature controller 4.

한편, 사용자가 온도 조절기(4)를 조절하여 원하는 온도가 되도록 설정하였을 경우 상기 온도 조절기(4)는 교류 파형의 전파를 통과시키는 '강'과 교류 파형의 반파만을 통과시키는 '약' 및 전원공급을 차단하는 '꺼짐'의 3단계로 조절되는 기능과, 교류 파형의 위상을 제어하여 리니어 제어를 수행하는 기능 및 직류(DC)를 사용하여 전압을 제어하는 휴대용으로 콤팩트하게 제작할 수 있는 기능으로 구분할 수 있다.On the other hand, when the user adjusts the temperature controller 4 to set the desired temperature, the temperature controller 4 supplies 'weak' for passing the electric wave of the AC waveform and 'weak' for passing only the half wave of the AC waveform and power supply. It can be divided into three functions of 'off' to cut off, a function to perform linear control by controlling the phase of AC waveform, and a compact and portable function to control voltage using direct current (DC). Can be.

이상에서 설명한 바와 같이, 본 고안의 다용도 온수 순환장치는 열효율을 극대화 시킬 수 있으며, 최소한의 설비로 필요한 만큼만의 발열을 이용할 수 있어 불필요한 전원소모를 극소화할 수 있고, 히터에 의해 가열된 순환수만을 사용하므로서 전자파가 발생하지 않고 화재의 위험에서 해소되며, 또한 순환수를 밀폐된 상태에서 수축작용을 하는 순환수 저장통에 저장하므로서 순환수 가열에 의한 순환수의 증발이 발생하지 않아 반 영구적으로 사용할 수 있으며 필요에 따라 밀폐 형태로 소형화시킬 수 있으며, 매트부등의 형태에 따라 다양한 용도 즉, 전기 장판의 대용, 전기판넬의 대용, 의료용 찜질기, 침대의 난방에 이용할 수 있는 다양한 효과가 있는 것이다.As described above, the multi-purpose hot water circulator of the present invention can maximize the thermal efficiency, can use only the heat generated as necessary with a minimum amount of equipment can minimize unnecessary power consumption, only the circulating water heated by the heater By using this product, electromagnetic waves are not generated and the risk of fire is eliminated.In addition, the circulating water is stored in a circulating water reservoir that contracts in a closed state, so that the circulating water cannot be evaporated by heating the circulating water so that it can be used semi permanently. And it can be miniaturized in a sealed form if necessary, and there are various effects that can be used for a variety of uses, such as electric blankets, electric panels, medical steamer, bed heating depending on the shape of the mat.
