배수 펌프 {DRAIN PUMP}Drain Pump {DRAIN PUMP}

본 발명은 차압센서를 이용하여 수위를 감지하는 배수 펌프에 관한 것이다.The present invention relates to a drain pump for detecting a water level using a differential pressure sensor.

펌프란 모터에 의하여 회전하는 임펠러의 회전력으로 유체를 이송하는 장치이고, 배수 펌프란 자연 배수가 되지 않는 곳에 설치되어 강제적으로 유체를 토출하는 장치이다.The pump is a device for transferring the fluid by the rotational force of the impeller rotated by the motor, the drain pump is installed in a place where natural drainage is not forced to discharge the fluid.

종래의 배수 펌프는 케이스, 상기 케이스의 내부에 회전가능하게 설치된 임펠러, 상기 케이스의 내부에 설치되며 상기 임펠러를 회전시키는 모터 및 상기 케이스의 일측에 설치된 제어부를 포함한다.The conventional drainage pump includes a case, an impeller rotatably installed in the case, a motor installed in the case and rotating the impeller, and a control unit installed at one side of the case.

상기 케이스에는 배수 펌프가 설치된 곳의 수위를 감지하는 플로 스위치(Flow Switch)가 설치된다. 상기 플로 스위치는 일단부측은 상기 제어부를 감싸는 커버의 내부에 위치되어 제어부측과 접속되고 타단부측은 상기 커버의 외부로 노출된 힌지바, 상기 힌지바의 타단부측에 결합되며 배수 펌프가 설치된 곳의 수면상에 뜨있는 플로트(Float)를 가진다.The case is provided with a flow switch (Flow Switch) for detecting the water level of the place where the drain pump is installed. One end of the flow switch is located inside the cover surrounding the control unit is connected to the control unit side and the other end is coupled to the hinge bar exposed to the outside of the cover, the other end side of the hinge bar, where the drain pump is installed Has a float on the surface of the

그리하여, 배수 펌프가 설치된 곳의 수면이 상승하면 상기 플로트가 상승하고, 상기 플로트의 상승에 따른 신호를 상기 제어부가 수신하여 상기 모터를 구동시킨다. 그러면, 상기 모터에 의하여 상기 임펠러가 회전하면서 유체를 외부로 배출한다. 그리고, 배수 펌프가 설치된 곳의 수면이 하강하면 상기 플로트가 하강하고, 상기 플로트의 하강에 따른 신호를 상기 제어부가 수신하여 상기 모터를 정지시킨다. 그러면, 상기 임펠러가 정지하여 유체가 배출되지 않는다.Thus, when the water surface of the place where the drain pump is installed rises, the float rises, and the controller receives a signal corresponding to the rise of the float to drive the motor. Then, the impeller rotates to discharge the fluid to the outside by the motor. When the water level of the place where the drain pump is installed is lowered, the float descends, and the controller receives a signal according to the descending of the float to stop the motor. Then, the impeller stops and no fluid is discharged.

상기와 같은 종래의 배수 펌프는 상기 플로 스위치의 일부분이 상기 커버의 외부로 노출되어 있으므로, 상기 커버의 외부로 노출된 상기 플로 스위치의 부위에 해당하는 만큼 설치 공간이 더 필요하다. 따라서, 배수 펌프를 설치하여 사용하기 위해서는 상대적으로 넓은 설치 공간이 필요한 단점이 있다.In the conventional drainage pump as described above, since a portion of the flow switch is exposed to the outside of the cover, an installation space is required as much as the portion of the flow switch exposed to the outside of the cover. Therefore, in order to install and use the drain pump, a relatively large installation space is required.

본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위하여 안출된 것으로, 본 발명의 목적은 제어부를 감싸는 커버의 내부에 수위 감지용 차압센서를 설치함으로써, 설치 공간을 감소시킬 수 있는 배수 펌프를 제공함에 있다.The present invention has been made to solve the problems of the prior art as described above, an object of the present invention is to provide a drain pump that can reduce the installation space by installing a differential pressure sensor for detecting the water level inside the cover surrounding the control unit.

이하, 첨부된 도면을 참조하여 본 발명의 일 실시예에 따른 배수 펌프를 상세히 설명한다.Hereinafter, a drain pump according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 일 실시예에 따른 배수 펌프의 사시도이고, 도 2는 도 1에 도시된 커버의 내면을 보인 사시도이다.1 is a perspective view of a drain pump according to an embodiment of the present invention, Figure 2 is a perspective view showing the inner surface of the cover shown in FIG.

도시된 바와 같이, 본 실시예에 따른 배수 펌프는 케이스(110)를 포함한다. 케이스(110)의 내부에는 모터(미도시)가 설치되고, 상기 모터 하측의 케이스(110)의 내부에는 상기 모터에 의하여 회전하는 임펠러(미도시)가 설치된다.As shown, the drain pump according to the present embodiment includes a case 110. A motor (not shown) is installed inside the case 110, and an impeller (not shown) rotated by the motor is installed inside the case 110 below the motor.

상기 임펠러가 회전하면 케이스(110) 외부에 고여있는 유체가 강제로 케이스(110)의 하부에 형성된 유입구(111)로 유입되어, 케이스(110)의 상면에 형성된 배출구(113)를 통하여 배출된다.When the impeller is rotated, the fluid accumulated in the case 110 is forced into the inlet 111 formed in the lower portion of the case 110, and is discharged through the outlet 113 formed in the upper surface of the case 110.

케이스(110)의 측면 일측에는 커버(120)가 결합되고, 커버(120)의 내부에는 상기 모터의 구동 등을 제어하는 제어부(130)가 설치된다. 즉, 제어부(130)는 커버(120)에 감싸여서 보호된다.The cover 120 is coupled to one side of the case 110, and a control unit 130 is installed inside the cover 120 to control driving of the motor. That is, the controller 130 is protected by being wrapped in the cover 120.

제어부(130)는 케이스(110)가 설치된 곳의 수위가 일정 이상이면, 상기 모터를 구동시켜 상기 임펠러를 회전시킨다. 그리고, 케이스(110)가 설치된 곳의 수위를 감지하기 위한 차압센서(140)가 커버(120)의 내부에 설치된다. 차압센서(140)는 제어부(130)와 접속되어 감지한 수위를 제어부(130)로 송신한다.The controller 130 drives the motor to rotate the impeller when the level of the place where the case 110 is installed is a predetermined value or more. Then, the differential pressure sensor 140 for detecting the water level where the case 110 is installed is installed inside the cover 120. The differential pressure sensor 140 is connected to the control unit 130 and transmits the detected water level to the control unit 130.

상세히 설명하면, 커버(120)의 내부에는 상단부는 차압센서(140)의 하측 부위와 연결되고 하단부는 커버(120)의 하측 부위에 지지된 제 1 연통관(151)이 설치되고, 일단부는 차압센서(140)의 상측 부위와 연결되고 타단부는 커버(120)의 상측 부위에 지지된 제 2 연통관(155)이 설치된다.In detail, the upper portion of the cover 120 is connected to the lower portion of the differential pressure sensor 140, and the lower portion is provided with a first communication tube 151 supported at the lower portion of the cover 120, one end of the differential pressure sensor The second communication tube 155 is connected to the upper portion of the 140 and the other end is supported on the upper portion of the cover 120.

제 1 연통관(151)의 하단부 및 제 2 연통관(155)의 타단부는 커버(120)의 외측과 연통되어, 케이스(110)가 설치된 곳에 고여있는 유체가 유입되는 것을 허용한다.The lower end of the first communication tube 151 and the other end of the second communication tube 155 communicate with the outside of the cover 120, allowing the fluid that is standing where the case 110 is installed.

그리하여, 제 1 연통관(151) 또는 제 2 연통관(155)을 통하여 유체가 유입되면 제 1 연통관(151) 또는 제 2 연통관(155)의 내부 압력이 변하고, 제 1 연통관(151) 또는 제 2 연통관(155)의 내부 압력을 차압센서(140)가 감지하여 제어부(130)로 송신하면, 제어부(130)는 설정된 값과 차압센서(140)에서 송신한 신호를 비교하여 상기 모터를 구동 또는 정지시킨다.Thus, when the fluid flows through the first communication tube 151 or the second communication tube 155, the internal pressure of the first communication tube 151 or the second communication tube 155 is changed, the first communication tube 151 or the second communication tube When the differential pressure sensor 140 detects the internal pressure of 155 and transmits the internal pressure to the controller 130, the controller 130 compares the set value with a signal transmitted from the differential pressure sensor 140 to drive or stop the motor. .

본 실시예에 따른 배수 펌프는 수위를 감지하는 차압센서(140)가 커버(120)의 내부에 설치되어 있으므로, 플로 스위치가 외부로 노출된 종래의 배수 펌프에 비하여 상대적으로 좁은 공간에 설치하여 사용할 수 있다.Since the differential pressure sensor 140 for detecting the water level is installed inside the cover 120, the drain pump according to the present embodiment is installed and used in a relatively narrow space compared to a conventional drain pump in which the flow switch is exposed to the outside. Can be.

본 실시예에 따른 배수 펌프는 자연 배수가 되지 않는 곳에 설치되어 사용되므로, 제 1 및 제 2 연통관(151, 155)으로는 이물질이 많이 함유된 오수(汚水)가 유입된다. 그러면, 오수에 함유된 이물질에 의하여 제 1 및 제 2 연통관(151, 155)의 내부가 쉽게 막힐 수 있다. 제 1 및 제 2 연통관(151, 155)의 내부가 막히게 되면, 제 1 및 제 2 연통관(151, 155)의 내부에 아무런 압력 변화가 없게 되므로, 상기 모터가 전혀 구동하지 않게 된다.Since the drain pump according to the present embodiment is installed and used in a place where natural drainage is not performed, filthy water containing a large amount of foreign matter flows into the first and second communication pipes 151 and 155. Then, the inside of the first and second communication pipes (151, 155) can be easily blocked by the foreign matter contained in the sewage. When the interior of the first and second communication pipes 151 and 155 is blocked, there is no pressure change inside the first and second communication pipes 151 and 155, so that the motor is not driven at all.

이를 방지하기 위하여, 본 실시예에 따른 배수 펌프에는 제 1 및 제 2 연통관(151, 155)의 내부를 뚫어서 청소할 수 있는 수단이 마련된다.In order to prevent this, the drain pump according to the present embodiment is provided with means for cleaning the inside of the first and second communication pipes (151, 155).

상기 수단은 제 1 연통관(151) 및 제 2 연통관(155)과 각각 연통되어 제 1 연통관(151) 및 제 2 연통관(155)으로 압축 공기가 공급될 수 있도록 안내하는 제 1 분기관(161) 및 제 2 분기관(165)으로 마련된다.The means communicates with the first communication pipe 151 and the second communication pipe 155, respectively, the first branch pipe 161 for guiding compressed air to be supplied to the first communication pipe 151 and the second communication pipe 155. And a second branch pipe 165.

제 1 분기관(161)의 상단부는 제 1 연통관(151)의 하단부측 외주면 부위와 연통되고 하단부는 커버(120)의 하측 부위에 지지되어 커버(120)의 외측과 연통된다. 그리고, 제 2 분기관(165)의 일단부는 제 2 연통관(155)의 타단부측 외주면 부위와 연통되고 타단부는 커버(120)의 상측 부위에 지지되어 커버(120)의 외측과 연통된다.The upper end portion of the first branch pipe 161 communicates with the outer peripheral surface portion of the lower end side of the first communication tube 151, and the lower end portion is supported by the lower portion of the cover 120 to communicate with the outside of the cover 120. One end of the second branch pipe 165 communicates with an outer peripheral surface portion of the other end side of the second communication tube 155, and the other end is supported by an upper portion of the cover 120 to communicate with the outside of the cover 120.

그러므로, 제 1 분기관(161) 또는 제 2 분기관(165)으로 압축 공기를 주입하면, 제 1 연통관(151) 또는 제 2 연통관(155)의 내부에 존재하는 이물질이 공기의 압력에 의하여 제 1 연통관(151)의 하단부 또는 제 2 연통관(155)의 타단부를 통하여 외부로 배출된다.Therefore, when compressed air is injected into the first branch pipe 161 or the second branch pipe 165, foreign matter present in the first communication pipe 151 or the second communication pipe 155 is removed by the air pressure. It is discharged to the outside through the lower end of the first communication tube 151 or the other end of the second communication tube 155.

제 1 분기관(161) 및 제 2 분기관(165)의 내부가 이물질에 의하여 막히는 것을 방지하기 위하여, 제 1 분기관(161)의 하단부 및 제 2 분기관(165)의 타단부에는 제 1 분기관(161) 및 제 2 분기관(165)을 개폐하는 마개(170)가 각각 삽탈가능하게 삽입된다. 제 1 분기관(161) 또는 제 2 분기관(165)을 통하여 압축 공기를 주입할 경우에만 마개(170)를 개방한다.In order to prevent the interior of the first branch pipe 161 and the second branch pipe 165 from being blocked by foreign matter, the lower end of the first branch pipe 161 and the other end of the second branch pipe 165 may have a first end. Plugs 170 for opening and closing the branch pipes 161 and the second branch pipes 165 are removably inserted, respectively. The stopper 170 is opened only when compressed air is injected through the first branch pipe 161 or the second branch pipe 165.
