Description

매트용 냉수 순환 공급장치Cold water circulation supply for mat
본 발명은 매트용 냉수 순환 공급장치에 관한 것으로서, 보다 상세하게는 냉동 사이클을 이용한 냉수 순환 공급장치에 비해 부피가 작고, 진동 및 소음이 적어 사용 편의성을 향상시킬 수 있는 매트용 냉수 순환 공급장치에 관한 것이다.The present invention relates to a cold water circulation supply device for a mat, and more particularly, to a cold water circulation supply device for a mat, which is smaller in volume and less vibration and noise than a cold water circulation supply device using a refrigeration cycle, thereby improving usability. It is about.
일반적으로 온수매트는 특허출원 제10-2009-0021259호의 종래기술에 개시된 바와 같이, 매트본체와, 온수보일러 및 순환호스로 크게 구성된다.In general, the hot water mat is largely composed of a mat body, a hot water boiler and a circulation hose, as disclosed in the prior art of Patent Application No. 10-2009-0021259.
이때, 상기 매트본체는 내측에 순환호스를 수용하며 온수보일러로부터 가열된 온수를 통해 난방되도록 형성된다.At this time, the mat body is formed to receive the circulation hose on the inside and is heated by hot water heated from the hot water boiler.
이때, 상기 온수보일러는 내측에 형성된 별도의 워터펌프와 순환호스를 통해 이송되는 물을 임시적으로 집수시켜 순간 가열시키도록 형성되는 온수조와, 상기 온수조의 내측에 부설되어 경유하는 물을 설정된 온도로 가열시키도록 형성되는 히터와, 상기 히터의 설정온도를 제어하거나 워터펌프의 운전을 제어하도록 형성되는 제어장치로 크게 구성된다.At this time, the hot water boiler is a hot water tank is formed to temporarily collect the water transported through the separate water pump and the circulation hose formed in the inner and instantaneous heating, and the water placed in the inner side of the hot water tank to pass through the water to a set temperature And a control device configured to control the set temperature of the heater or to control the operation of the water pump.
다시 말해, 종래의 온수매트는 일반적인 전기매트 전열선 대신 매트 내부에 난방수가 흐를 수 있는 호스관을 매설하고, 소형 전기 보일러로 가열한 물을 호스관(튜브) 내로 순환시키는 방법으로 매트를 가열할 수 있도록 형성된다.In other words, in the conventional hot water mat, the mat can be heated by embedding a hose tube through which a heating water can flow inside the mat instead of a general electric mat heating wire, and circulating water heated by a small electric boiler into the hose tube (tube). So that it is formed.
그러나, 종래에는 오로지 온수만을 제공하여 겨울철에만 사용되는 온수매트가 제공되고 있을 뿐, 여름철에 사용할 수 있는 냉수 매트가 전무하여 소비자의 출시 요구가 계속되고 있는 실정이다.However, in the related art, only hot water is provided to provide only hot water, and thus only a hot water mat used in winter is provided, and there is no cold water mat that can be used in summer.
이에, 최근에는 냉수를 온수와 개별로 구동하여 냉난방을 임의 선택에 따라 구동시킬 있는 매트가 특허출원 제10-2005-0022394호에 개시되어 있기는 하나, 이러한 냉수 및 온수공급 방식은 난방의 경우 외부의 별도의 보일러에서 물을 가열하여 매트 내부에 공급하고, 이를 워터펌프로 돌려서 물을 순환시키는 방식으로 작동하며, 냉각의 경우 워터펌프로 물을 순환하여 물이 침대를 돌고 나서 외부의 컨트롤 장치를 거치는 사이 자연적으로 열을 발산하여 다시 매트로 공급되는 방식으로, 실제로 냉각되는 정도가 작을 뿐만 아니라 물이 공급되는 대상인 침대에 열원이 있을 경우 오히려 수온이 상승되어 실제적인 냉각효과가 거의 없는 문제점이 계속되고 있는 실정이다.Therefore, recently, a mat that can drive cold water separately from hot water to drive cooling and heating according to an arbitrary choice has been disclosed in Patent Application No. 10-2005-0022394. It operates by heating water in a separate boiler of the inside of the mat and circulating the water by rotating it to the water pump.In the case of cooling, the water is circulated by the water pump to turn the external control device In the process of dissipating heat naturally and feeding back to the mat during the process, not only is the degree of cooling actually small, but if there is a heat source in the bed to which water is supplied, the water temperature rises, so that there is little practical cooling effect. It's happening.

상기 케이스(110)의 제1격벽(114)에 의해 제1수용공간(111)과 분리 구획된 제2수용공간(112)에는 저장탱크(120)와 워터펌프(150)가 수용되고, 제2격벽(115)에 의해 제2수용공간(112)과 분리 구획된 제3수용공간(113)에는 제어부(160)가 수용된다. 상기와 같이 케이스(110) 내부에 수용되어 전원이 인가되는 워터펌프(150)와 제어부(160)가 각각 제2수용공간(112)과 제3수용공간(113)으로 분리 수용되므로, 제1수용공간(111)으로부터 축냉카트리지(140)를 착탈하는 과정에서 발생할 수 있는 감전 사고의 위험을 최소화할 수 있다. The storage tank 120 and the water pump 150 are accommodated in the second accommodation space 112 separated from the first accommodation space 111 by the first partition wall 114 of the case 110. The controller 160 is accommodated in the third accommodation space 113 separated from the second accommodation space 112 by the partition wall 115. As described above, since the water pump 150 and the control unit 160 accommodated in the case 110 are applied to the second accommodation space 112 and the third accommodation space 113, respectively, the first accommodation is accommodated. The risk of an electric shock that may occur in the process of detaching the cold storage cartridge 140 from the space 111 may be minimized.
도 7 및 도 8에서 도시하는 바와 같이, 저장탱크(120)는 유입관(121)을 통해 냉각 매트 배관(P)의 배출측 단부(P2)와 연결되어 냉각 매트를 통과한 유체가 저장탱크(120) 내부의 저장공간으로 유입된다. 저장공간에 저장된 유체는 워터펌프(150)의 구동에 의해 소정의 압력으로 열교환부(130)의 입수부(132)로 공급되며, 입수부(132)로 공급된 유체는 유체 이동통로(131)를 통과하는 과정에서 열교환부(130)의 측면에 밀착된 축냉카트리지(140)와의 열교환에 의해 냉각되며, 냉각된 유체는 출수부(133)를 통해 냉수 매트(M) 배관(P)의 공급측 단부(P1)로 제공된다. As shown in FIG. 7 and FIG. 8, the storage tank 120 is connected to the discharge side end P2 of the cooling mat pipe P through the inlet pipe 121 so that the fluid passing through the cooling mat is stored in the storage tank ( 120) flows into the storage space. The fluid stored in the storage space is supplied to the inlet 132 of the heat exchanger 130 at a predetermined pressure by driving the water pump 150, and the fluid supplied to the inlet 132 is a fluid movement passage 131. Cooled by heat exchange with the cold storage cartridge 140 in close contact with the side of the heat exchanger 130 in the process of passing through, the cooled fluid is supplied to the supply side end of the cold water mat (M) pipe (P) through the water outlet (133) Provided at (P1).
한편, 열교환부(130)와 축냉카트리지(140)는 다수 마련되어 서로 교대로 배치되고, 다수의 열교환부(130)에 각각 마련된 유체 이동통로(131)는 서로 연결되므로 축냉카트리지(140)와의 열교환을 위한 시간 및 면적을 충분히 확보할 수 있다. 또한, 케이스(110)의 제1수용공간(111) 내벽면에는 단열재(116)가 마련되어 있으므로, 축냉카트리지(140)의 냉기가 케이스(110) 외부로 손실되는 것을 방지할 수 있다. On the other hand, the heat exchange unit 130 and the cold storage cartridge 140 is provided with a plurality of alternately arranged, and the fluid movement passages 131 provided in each of the plurality of heat exchange unit 130 are connected to each other to exchange heat with the cold storage cartridge 140 Enough time and area can be secured. In addition, since the heat insulating material 116 is provided on the inner wall surface of the first accommodating space 111 of the case 110, it is possible to prevent cold air of the heat storage cartridge 140 from being lost to the outside of the case 110.
특히, 상기 케이스(110)의 내벽면과 열교환부(130) 사이에 개재된 탄성부재(118)에 의해 열교환부(130)가 축냉카트리지(140)와 밀착하는 방향으로 가압되므로, 축냉카트리지(140)와 열교환부(130)의 밀착면이 이격되어 열교환 효율이 낮아지는 것을 방지할 수 있다. In particular, the heat exchange part 130 is pressed in a direction in close contact with the heat storage cartridge 140 by the elastic member 118 interposed between the inner wall surface of the case 110 and the heat exchange unit 130, the heat storage cartridge 140 ) And the contact surface of the heat exchanger 130 is spaced apart to prevent the heat exchange efficiency is lowered.
또한, 다수의 열교환부(130)는 가이드부(135)에 의해 제1수용공간(111) 내에서 제1방향으로 이동 가능한 상태로 배치된다. 따라서 축냉카트리지(140)의 두께가 열변형에 의해 변경되더라도 다수의 열교환부(130)와 축냉카트리지(140)의 밀착상태가 유지되도록 할 수 있다. In addition, the plurality of heat exchangers 130 may be disposed in a state of being movable in the first direction in the first accommodation space 111 by the guide part 135. Therefore, even if the thickness of the cold storage cartridge 140 is changed by thermal deformation, it is possible to maintain the close contact state of the plurality of heat exchange parts 130 and the cold storage cartridge 140.
여기서, 제어부(160, 도 6 참조)를 통해 상기 워터펌프(150)의 구동을 제어할 수 있다. 구체적으로, 제어부(160)는 유체의 온도를 측정하는 온도센서(미도시)와, 워터펌프(150)의 구동주기를 제어하기 위한 타이머(미도시) 중 적어도 어느 하나에서 얻은 값을 이용해 워터펌프(150)가 자동으로 제어되도록 함으로써 축냉카트리지(140)의 교환 주기를 최대로 연장할 수 있으며, 저장탱크(120)에 저장된 유체의 수위를 측정하는 수위센서(미도시)를 통해 유체의 보충시기를 사용자에게 알리는 등의 기능을 제공함으로써, 사용 편의를 향상시킬 수 있다. Here, the driving of the water pump 150 may be controlled through the controller 160 (see FIG. 6). In detail, the controller 160 uses a value obtained from at least one of a temperature sensor (not shown) for measuring the temperature of the fluid and a timer (not shown) for controlling the driving period of the water pump 150. By allowing the 150 to be automatically controlled, the replacement cycle of the cold storage cartridge 140 can be extended to the maximum, and the replenishment timing of the fluid through a water level sensor (not shown) for measuring the level of the fluid stored in the storage tank 120. By providing a function for notifying the user, etc., it is possible to improve the convenience of use.
