Abstract

A water filling electromagnetic valve and check valve are provided at the upstream side and downstream side of a sensor respectively. A vacuum breaker is arranged between the sensor and check valve. These valves are integrally formed in the same housing. An incoming path of the sensor is narrowed to have a slightly smaller diameter than that of an outgoing path of electromagnetic valve. The flow of water passing within the outgoing path of the electromagnetic valve flows into the incoming path of the sensor is rectified beforehand in the outgoing path of the electromagnetic valve and moreover owing to the fact that the incoming path is narrowed, an impeller is rotated while the water flow is stable. Accordingly, the flow rate can be measured in a stable manner, with errors reduced.

본 발명은 온수채움 지시에 따라서 자동적으로 온수채움을 행하는 온수채움기능을 갖는 급탕기등에 있어서 온수채움유량을 검지하기 위한 밸브장치가 부착된 유량센서에 관한 것이다.The present invention relates to a flow sensor with a valve device for detecting the hot water filling flow rate in a hot water heater having a hot water filling function for automatically filling hot water according to the hot water filling instruction.

온수채움기능을 갖는 자동급탕기와 같이, 온수채움의 지시에 따라서 소정의 유량을 욕조에 자동적으로 공급하는 것에서는 욕조에 공급되는 온수량을 유량센서에 의하여 검지하여 그 검지량의 적산치를 산출하고, 소정의 수량이 공급됐을 때에 급탕이 종료한다.In the case of automatically supplying a predetermined flow rate to the bathtub in accordance with the instruction of the hot water filling, such as an automatic hot water heater having a hot water filling function, the amount of hot water supplied to the bathtub is detected by a flow sensor to calculate an integrated value of the detected amount. Hot water supply is complete | finished when predetermined quantity was supplied.

이런 유량센서는 종래에는 급탕기의 하류에 설치된 욕조로의 온수채움회로로의 접속관중에 설치되어 있다.Such a flow sensor is conventionally installed in a connection pipe to a hot water filling circuit to a bathtub installed downstream of a hot water heater.

종래에는 유량센서 단체로서 사용할수 있는 것이 이용되고 있었지만, 유량센서 상류의 유로의 형상 및 유량센서와 접속되는 급탕기의 출탕관등과의 부착시에 오차에 의해 수류에 난류가 생기기 쉽고, 수류에 의하여 회전하는 임펠러에 대하여 수류가 정확히 명중하지 않으면 유량의 검출 정밀도에 오차가 생기기 쉬운 문제가 있었다.Conventionally, the one that can be used as a flow sensor alone has been used, but turbulence tends to occur due to an error when the shape of the flow path upstream of the flow sensor and the tapping pipe of the hot water heater connected to the flow sensor, etc., cause errors. If the water flow does not hit the impeller precisely, there is a problem that an error easily occurs in the detection accuracy of the flow rate.

본 발명은 주로 욕조에 자동적으로 온수채움을 행하기 위하여 설치된 유량센서에 있어서, 필요한 유량검출 정밀도가 얻어짐과 동시에, 제조공정이 간단하고 게다가 온수채움장치에 사용하는 경우에 염가로 유량센서를 제공하는 것을 목적으로 한다.The present invention mainly provides a flow rate sensor which is provided for automatically filling hot water in a bathtub, and at the same time, the required flow rate detection accuracy is obtained, and the manufacturing process is simple, and the flow rate sensor is provided at low cost when used in a hot water filling device. It aims to do it.

본 발명은 급탕기로부터 욕조에 접속된 온수채움회로중에 상기 욕조에 공급되는 온수의 유량을 검지하기 위해 설치되며, 하우징에 형성된 유입로로부터 유입하는 온수에 의하여 회전하는 임펠러를 구비한 유량센서에 있어서, 상기 유입로의 상류에는 상기 욕조로의 온수공급을 제어하기 위한 전자밸브가 구비되며, 상기 전자밸브의 유출로는 상기 유입로에 대하여 직선상에 위치하고 상기 유입로와 일체로 상기 하우징에 형성됨과 동시에, 상기 전자밸브의 유출로의 내경은 밸브체에 의하여 개폐되는 밸브시이트의 내경 이하로 설정된 것을 기술적 수단으로 한다.The present invention is a flow sensor having an impeller installed to detect the flow rate of the hot water supplied to the bathtub in the hot water filling circuit connected to the bathtub from the hot water heater, and rotated by the hot water flowing from the inlet formed in the housing, Upstream of the inflow passage is provided with a solenoid valve for controlling the hot water supply to the bath, the outlet of the solenoid valve is located on a straight line with respect to the inflow passage is formed in the housing integrally with the inflow passage The inner diameter of the outflow path of the solenoid valve is set to be equal to or smaller than the inner diameter of the valve seat opened and closed by the valve body.

본 발명의 유량센서에서는, 전자밸브의 유출로가 유량센서의 유입로에 대하여 직선상에 위치하고, 유입로와 일체로 형성되어 있어 전자밸브의 유출로의 내경이 밸브시이트의 내경 이하로 설정되어 있기 때문에 밸브시이트를 통과하는 온수는 유출로에서 정류되어 유량센서의 유입로를 통과한다.In the flow sensor of the present invention, the outflow path of the solenoid valve is located on a straight line with respect to the inflow path of the flow sensor and is integrally formed with the inflow path so that the inner diameter of the outflow path of the solenoid valve is set to be less than or equal to the inner diameter of the valve seat. Therefore, the hot water passing through the valve seat is rectified in the outflow passage and passes through the inflow passage of the flow sensor.

유량센서의 유입로는 전자밸브의 유출로의 직선상에 있기 때문에 유출로로부터 유출한 온수는 혼란없이 유량센서의 임펠러를 회전시킨다.Since the inflow path of the flow sensor is in a straight line to the outflow path of the solenoid valve, the hot water discharged from the outflow path rotates the impeller of the flow sensor without confusion.

따라서, 검출유량에 오차가 없이 안정한 유량검출을 할수 있기 때문에 매회의 온수채움시에 있어서, 온수채움량의 적산치에 오차가 없이 정밀도가 좋은 온수채움을 행할수 있다.Therefore, since the stable flow rate detection can be performed without any error in the detected flow rate, it is possible to perform hot water filling with high precision without any error in the integrated value of the hot water filling amount at each time of hot water filling.

또한, 전자밸브와 유량센서가 일체로 설치되어 있기 때문에 온수채움회로로의 접속 부착공정수가 감소하고, 온수채움장치로서의 가격을 저감시키는 효과를 갖는다.In addition, since the solenoid valve and the flow rate sensor are integrally installed, the number of steps for attaching and connecting the hot water filling circuit can be reduced, thereby reducing the price of the hot water filling device.

이하 본 발명을 실시예에 근거하여 설명한다.Hereinafter, the present invention will be described based on Examples.

제2도는 본 발명의 밸브장치가 부착된 유량센서(30)을 이용한 온수채움장치 (1)을 나타낸다.2 shows the hot water filling device 1 using the flow sensor 30 with the valve device of the present invention.

이 온수채움장치(1)는 급탕 및 온수채움을 행하기 위한 온수를 공급하기 위한 주급탕기(10)과, 욕조(b)와 접속된 재가열용가열기(20)과, 주급탕기(10)와 재가열용가열기(20)을 접속하는 온수채움과(2)으로 구성되며, 본 발명의 밸브장치가 부착된 유량센서(30)는 온수채움관(2)중에 설치된다.The hot water filling device 1 includes a main water heater 10 for supplying hot water for hot water supply and hot water filling, a reheater 20 connected to the bathtub b, a main water heater 10, and a reheater. It consists of a hot water filling section (2) connecting the molten heater (20), the flow rate sensor 30 with a valve device of the present invention is installed in the hot water filling pipe (2).

주급탕기(10)는 주열교환기(11)에 물을 유도하는 급수관(12)가 상수도 등의 도시하지 않은 물공급원과 접속되며, 주열교환기(11)로부터 온수가 유출하는 출탕관(13)에는 몇개의 급탕구가 설치된 급탕관(14)가 상술한 온수채움관(2)가 분기하여 접속되어 있다.The main water heater 10 has a water supply pipe 12 for inducing water to the main heat exchanger 11 is connected to a water supply source (not shown), such as running water, and the tap water pipe 13 through which hot water flows out from the main heat exchanger 11. The hot-water filling tube 2 is branched and connected to the hot-water supply pipe 14 provided with the hot water supply opening of.

한편, 재가열용급탕기(20)은 목욕물 열교환기(21)과 욕조(b)의 사이에 순환용배관(22), (23)이 접속되며, 한쪽의 순환용 배관(22)에는 욕조(b)내의 온수를 순환시키기 위한 펌프(24)가 설치되며, 상술한 온수채움관(2)는 펌프(24)의 하류에서 순환용배관(22)와 접속되어 있다.On the other hand, the hot water heater 20 for reheating is connected to the circulation pipe 22, 23 between the bath water heat exchanger 21 and the bath (b), the tub (22) to one circulation pipe (22). A pump 24 for circulating hot water therein is provided, and the hot water filling pipe 2 described above is connected to the circulation pipe 22 downstream of the pump 24.

또한, 각 열교환기(11), (21)에는 각각 주버너(15)아 목욕물버너(25)가 구비되어 있다.Moreover, each heat exchanger 11 and 21 is equipped with the main burner 15 and the bath water burner 25, respectively.

밸브장치가 부착된 유량센서(30)은 제1도에 도시한 바와 같이, 유량센서(31)을 중심으로 하여 그 상류측에는 온수채움 전자밸브부(40)이 그리고 하류측에는 체크밸브부(50)이 설치되고, 유량센서(31)과 체크밸브부(50)과의 사이에는 진공브레이커(55)가 배치되어, 이들이 동일의 하우징(30a)에 일체로 형성된 것이다.As shown in FIG. 1, the flow rate sensor 30 equipped with a valve device has a hot water filling solenoid valve portion 40 on the upstream side thereof and a check valve portion 50 on the downstream side thereof. The vacuum breaker 55 is disposed between the flow rate sensor 31 and the check valve portion 50, and these are integrally formed in the same housing 30a.

유량센서(31)은 임펠러실(32)내에 임펠러(33)이 자유롭게 회전하도록 배치된것으로, 임펠러(33)의 사프트(34)에는 제3도에 나타낸 바와 같이 환상의 마그네트(35)가 부착되어 있다.The flow sensor 31 is disposed so that the impeller 33 freely rotates in the impeller chamber 32. An annular magnet 35 is attached to the shaft 34 of the impeller 33 as shown in FIG. have.

하우징(30a)에는, 임펠러실(32)내의 임펠러(33)으로 향하여 소정의 각도로 수류가 닿도록 유입로(36)의 연장선상을 임펠러실(32)내의 물이 유출하는 유출로(37)이 유입로(36)보다 약간직경을 크게하여 형성되어 있다.Outflow path 37 through which the water in the impeller chamber 32 flows out on the extension line of the inflow path 36 so that water flows at a predetermined angle toward the impeller 33 in the impeller chamber 32. The diameter is slightly larger than that of the inflow path 36.

온수채움 전자밸브부(40)은, 상술한 바와 같이 유량센서(31)의 상류에 유량센서(31)이 형성된 하우징(30a)에 일체로 설치된 것으로, 제4도에 도시한 바와 같이, 제1도의 안쪽방향으로 유입구(41)이 설치되며, 유입구(41)로부터는 동일하게 제1도에 있어서 안쪽방향으로부터 지면방향으로 향해 원통상의 유입로가 형성되어 있다.The hot water filling solenoid valve part 40 is integrally installed in the housing 30a in which the flow sensor 31 was formed upstream of the flow sensor 31 as mentioned above, As shown in FIG. The inflow port 41 is provided in the inward direction of the figure, and the inflow port 41 is similarly formed from the inflow port 41 toward the ground direction from the inward direction to the ground direction in FIG.

원통상의 유입로(42)의 말단은 밸브체(43)에 의하여 개폐되는 밸브시이트(44)를 형성하고, 유입로(42)의 내측에는 유입로(42)와 동심상으로 직선형상의 유출로(45)가 설치되어 있다.The end of the cylindrical inflow passage 42 forms a valve seat 44 which is opened and closed by the valve body 43, and the inflow passage 42 has a straight outflow passage concentric with the inflow passage 42. 45 is provided.

여기서, 유출로(45)의 내경은 밸브시이트(44)의 내경과 동일하며, 밸브시이트(44)의 내경보다 크게 되는 일이 없이 바로 하류의 유량센서(31)의 유입로(36)과 접속되도록 하여 일체로 형성되어 있다.Here, the inner diameter of the outflow path 45 is the same as the inner diameter of the valve seat 44, and is connected to the inflow path 36 of the flow sensor 31 immediately downstream without becoming larger than the inner diameter of the valve seat 44. It is formed integrally as possible.

이 때문에, 유입로(42)에 유입한 온수는 그 중심에 있는 유출로(45)를 향하여 밸브시이트(44)를 통하여 주위로부터 균등하게 흘러 들어가게 되기 때문에 유출로(45)에 대하여 정류효과가 있고, 유출로(45)를 통과하는 탕수에는 난류가 적어진다.For this reason, since the hot water flowing into the inflow path 42 flows evenly from the surroundings through the valve seat 44 toward the outflow path 45 in the center, it has a rectifying effect with respect to the outflow path 45. , The turbulence flows less in the hot water passing through the outflow passage 45.

또한, 유출로(45)는 곧 하류의 유량센서(31)의 유입로(36)에 대하여 직선적인 유체로 되어 있기 때문에, 온수채움 전자밸브부(40)의 유출로(45)내를 통과하는 수류는 난류가 되는 일이 없이 정류상태가 유지된 상태로 유입로(36)을 통과하고, 임펠러(33)에 대하여 적절한 각도의 수류로서 임펠러실(32)를 통과하고, 임펠러(33)을 안정하게 회전시킨다.In addition, since the outflow passage 45 is a straight fluid with respect to the inflow passage 36 of the downstream flow sensor 31, the outflow passage 45 passes through the outflow passage 45 of the hot water filling solenoid valve portion 40. The flow of water flows through the inflow path 36 in a state in which the steady state is maintained without becoming turbulent, passes through the impeller chamber 32 as a flow of water at an appropriate angle with respect to the impeller 33, and stabilizes the impeller 33. Rotate it.

또한, 여기서는 유량센서(31)의 유입로(36)은 온수채움 전자밸브부(40)의 유출로(45)보다 약간 직경이 작게 조여있기 때문에 온수채움 전자밸브부(40)의 유출로(45)내를 통과한 수류는 정류상태가 보다 안정되어 유입로(36)에 유입된다.In addition, since the inflow path 36 of the flow sensor 31 is tightened slightly smaller than the outflow path 45 of the hot water filling solenoid valve part 40, the outflow path 45 of the hot filling solenoid valve part 40 is reduced. The flow of water flowing through the inside is more stable and flows into the inflow path (36).

이와 같이 유량센서(31)의 유입로(36)을 통과하는 수류는 온수채움 전자밸브부(40)의 유출로(45)에서 미리 정류되며, 게다가 유입로(36)에 있어서의 조임효과에 의하여 보다 한정한 수류가 되어 임펠러(33)을 회전시키기 때문에 안정한 유량측정을 할수 있으며, 오차가 적어질수 있다.In this way, the water flow passing through the inflow path 36 of the flow sensor 31 is rectified in advance in the outflow path 45 of the hot water filling solenoid valve part 40, and furthermore, due to the tightening effect in the inflow path 36. Since the impeller 33 rotates due to more limited water flow, stable flow rate measurement can be achieved, and errors can be reduced.

유량센서(31)의 유출로(37)에는 진공 브레이커(55)가 설치되며, 단 수시와 같은 경우에 상수도측에 부압력이 생겼을 때 온수채움관(2)를 대기로 개방하여 욕조(b)로부터의 온수의 역류를 방지한다.A vacuum breaker 55 is installed in the outflow path 37 of the flow rate sensor 31, and when the negative pressure is generated on the water supply side in the same case as in the case of the water flow, the hot water filling pipe 2 is opened to the atmosphere to open the bathtub (b). Prevent backflow of hot water from

유출로(37)의 하류측에는 재가열시 등에 욕조(b)로부터의 온수가 역류하지 않도록 하기 위한 체크밸브부(50)이 형성되며, 체크밸브부(50)에는 2개의 밸브체(51), (52)가 설치되어 있다.On the downstream side of the outflow passage 37, a check valve portion 50 is formed to prevent the hot water from the bath b from flowing back during reheating, and the check valve portion 50 has two valve bodies 51, ( 52) is installed.

또한, 하우징(30a)는 복수의 내열성 수지를 조합하여 구성되며, 그 외부에는 유량센서(31)에 있어서 마그네트(35)의 회전수를 검출하기 위하여 설치된 홀 IC등으로 이루어진 자기센서(38)과, 온수채움 전자밸브부(40)에 있어서 밸브체(43)을 구동하기 위한 코일등으로 이루어진 액츄에이터(46)이 구비되어 있다.In addition, the housing 30a is configured by combining a plurality of heat-resistant resins, the outside of which is composed of a magnetic sensor 38 made of a hall IC or the like provided for detecting the rotational speed of the magnet 35 in the flow sensor 31. In the hot water filling solenoid valve part 40, the actuator 46 which consists of a coil etc. for driving the valve body 43 is provided.

이상의 구성으로 이루어진 본 실시예의 온수채움장치(1)에는 도시하지 않은 콘트롤러의 조작에 따라서 주급탕기(10) 및 재가열용가열기(20)을 제어하는 제어유니트(60)이 구비되며, 사용자의 지시에 따라서, 또는 각 급탕구의 급탕전을 개방하면 소정의 제어가 행해져 필요한 온수가 공급된다.The hot water filling device 1 of the present embodiment having the above configuration is provided with a control unit 60 for controlling the main water heater 10 and the reheater heater 20 according to an operation of a controller (not shown). Therefore, when the hot water supply of each hot water supply opening is opened, predetermined control is performed and necessary hot water is supplied.

또한, 제어유니트(60)은 콘트롤러의 조작에 따라서 밸브장치가 부착된 유량센서(30)의 온수채움 전자밸브부(400의 개폐제어도 행하고, 지시에 따라서 온수채움 전자밸브부(40)을 개방하여 온수채움을 개시함과 동시에, 지정된 수량이 욕조(b)에 공급된 것이 유량센서(31)에 의한 적산치에 의하여 검지되면 자동적으로 온수채움 전자밸브부(40)을 폐쇄하여 온수채움을 마친다.In addition, the control unit 60 also controls the opening and closing of the hot water filling solenoid valve portion 400 of the flow sensor 30 with the valve device according to the operation of the controller, and opens the hot water filling solenoid valve portion 40 according to the instruction. By starting the hot water filling and at the same time, when the specified quantity is supplied to the bath (b) by the integrated value by the flow sensor 31, the hot water filling solenoid valve unit 40 is automatically closed to finish the hot water filling. .

이 경우, 유량센서(31)은 온수채움 전자밸브부(40)의 하류에 위치하고, 온수채움이 행하여 지지 않는 경우에는 상수도의 수압이 증가되는 일이 없기 때문에 하우징(30a)에는 본 실시예와 같이 수지를 이용할수 있으며 금속을 이용할 필요가 없다.In this case, the flow rate sensor 31 is located downstream of the hot water filling solenoid valve portion 40, and when the hot water filling is not performed, the water pressure of the tap water does not increase. Resin is available and there is no need to use metal.

또한, 임펠러(33)은 온수채움 전자밸브부(40)을 통과하여 압력이 저하한 온수에 의하여 회전구동되기 때문에 임펠러(33)과 임펠러(33)의 베어링부분의 열화가 작아지고, 또한 이 부분에 이용하는 부재에 대해서도 수지를 이용할수 있다.In addition, since the impeller 33 is rotated by hot water whose pressure has passed through the hot water filling solenoid valve portion 40, the deterioration of the bearing portions of the impeller 33 and the impeller 33 is reduced, and this portion Resin can also be used also for the member used for the.

따라서, 충분한 내구성을 확보하면서 하우징(30a) 및 그의 내부구조에 관해서의 제조가 용이해지기 때문에 밸브기구가 부착된 유량센서를 저렴하게 만들수 있다.Therefore, since the manufacture of the housing 30a and its internal structure is easy while ensuring sufficient durability, the flow rate sensor with a valve mechanism can be made cheap.

또한, 임펠러(33)에 닿는 온수는 온수채움 전자밸브부(40)의 직선형상의 유출로(45)에 의하여 정류되며, 유출로(45)와 직선상에 설치된 유입로(36)에 의하여 정류가 유지되기 때문에 임펠러(33)의 회전이 안정해지고, 매회의 온수채움에 있어서 회전에 오차가 없기 때문에 유량검출에 있어서 필요한 정밀도가 유지된다.In addition, the hot water that reaches the impeller 33 is rectified by the straight outflow passage 45 of the hot water filling solenoid valve portion 40, the rectification is by the inflow passage 45 and the inflow passage 36 installed in a straight line. Since the rotation of the impeller 33 is stabilized, the rotation of the impeller 33 is stabilized, and since there is no error in the rotation of the hot water filling each time, the required precision in the flow rate detection is maintained.
