Description

철도차량용 진공식 화장실의 배수장치Drainage of vacuum toilets for railway vehicles

본 발명은 철도차량용 진공식 화장실 유니트의 세정수 공급부에 잔류되어진 세정수를 배출하는 장치에 관한 것으로, 특히 배수밸브를 조작하여 급수탱크에 저장된 물을 배수시킬 때, 급수장치의 세정수 공급부에 잔류된 세정수가 자동으로 배수되도록 하여, 동절기 기온하강시 잔류 세정수에 의한 동파가 방지되도록 된 철도차량용 진공식 화장실의 배수장치에 관한 것이다.The present invention relates to a device for discharging the washing water remaining in the washing water supply unit of the vacuum toilet unit for railway vehicles, in particular, when the water stored in the water supply tank is drained by operating the drain valve, the water remaining in the washing water supply unit of the water supply device The present invention relates to a drainage system of a vacuum toilet for a railroad car, by allowing the used washing water to be automatically drained to prevent freezing by residual washing water during the winter temperature drop.

통상적으로 철도차량에는 급수탱크와 급수배관내의 잔류수를 배수하는 장치가 구비되어 동절기시 모든 급수장치 부분의 동파가 방치되도록 있어 있는데, 화장실의 세정수 공급부는 이러한 배수장치를 작동하더라도 배수가 제대로 이루어지지 못하여 잔류수에 의한 동파가 빈번하게 발생되는 문제가 있었다.In general, railway vehicles are equipped with a device for draining residual water in the water supply tank and the water supply pipe so that freezing of all water supply parts is left during the winter season. There was a problem that the freeze caused by the residual water frequently occurs.

따라서, 화장실의 세정수 공급부의 잔류수에 의한 동파를 방지하기 위해서는 우선 상기 배수장치를 작동하여 급수장치의 배수를 완료한 후 별도로 작업자가 화장실의 세정 버튼을 여러 번 눌러 화장실 공급부에 남아있는 잔여세정수를 따로 배수하는 작업이 필요하게 된다.Therefore, in order to prevent freezing caused by residual water in the washing water supply part of the toilet, first, after the drainage device is operated to complete drainage of the water supply device, the worker separately presses the washing button of the bathroom several times and the remaining cleaning remaining in the toilet supply part is performed. It is necessary to drain the water separately.

종래 화장실의 세정수 공급부의 잔류수가 배수되는 상태를 도 2를 참조로 하여 이하 보다 상세히 설명하기에 앞서서 굵은 점선은 공기흐름을 나타내고, 굵은 실선을 물의 흐름, 그리고 가는 2점쇄선은 전기의 연결을 나타내는 것임을 이해를 돕기 위하여 미리 밝혀 주는 바이다.Before explaining the state in which the residual water of the washing water supply part of the conventional toilet is drained in detail with reference to FIG. 2, the thick dotted line indicates the air flow, the thick solid line indicates the flow of water, and the thin two-dot chain line indicates the electrical connection. It is indicated beforehand to help understanding.

철도차량 운행중 평상시에는 공급전자밸브(6)가 개방된 상태로 유지되고, 세정전자밸브(7)와 가압전자밸브(2)는 각각 닫혀 있으므로 차단코크(11)를 통하여 급수라인으로부터 공급되는 세정수는 제1지역밸브(8a)·세정전자밸브(7) 사이와, 급수가압기(4)의 내부에 유입되는데, 화장실 사용자가 세정버튼(도시안됨)을 누르면 우선 가압전자밸브(2)가 열리며 공압이 급수가압기(4)에 전달되어 급수가압기(4) 내부의 세정수를 두 역지밸브(8a,8b) 사이로 밀어내므로 제1역지밸브(8a)와 세정전자밸브(7) 사이의 세정수가 가압되고, 이후 세정전자밸브(7)가 열리며 가압된 세정수가 변기(5)로 분출되어 변기(5) 내부가 세척된다.Since the supply solenoid valve 6 is kept open and the solenoid valve 7 and the pressurized solenoid valve 2 are closed during the operation of the railway vehicle, the washing water supplied from the water supply line through the shutoff cock 11 is normally closed. Is introduced between the first zone valve (8a) and the washing solenoid valve (7) and inside the water supply pressurizer (4). When the toilet user presses the cleaning button (not shown), the pressurized solenoid valve (2) is opened. Pneumatic pressure is delivered to the water supply pressurizer 4 to push the washing water inside the water supply pressurizer 4 between the two check valves 8a and 8b, so that the washing water between the first check valve 8a and the cleaning solenoid valve 7 After being pressurized, the washing solenoid valve 7 is opened and the pressurized washing water is ejected to the toilet bowl 5 to clean the inside of the toilet bowl 5.

한편, 철도차량의 운행중에는 공압이 배수밸브(1)를 통해서 제1공압 공급라인(a)으로 유입되어 급수탱크(도시안됨) 내부 압력이 소정치 이상으로 가압되는 상태를 유지하므로, 급수탱크에 저장된 물이 차단코크(11)를 통해서 연속적으로 공급되지만, 철도차량의 운행이 종료된 후, 운전자가 배수밸브(1)를 누르면 공압이 제2공압 공급라인(b)으로 유입되어 급수탱크의 배수용 전자밸브(도시안됨)가 열리게 되므로, 급수탱크 및 급수라인 내의 잔류수가 외부로 배출되는데, 도 2 상에서 a로 표시되어진 세정수 공급부의 잔류 세정수는 배수가 제대로 이루어지지 못하므로, 상기 세정버튼을 수차례 반복 조작하여 세정수 공급부의 잔류 세정수를 배출하게 된다.On the other hand, during operation of the railway vehicle, the pneumatic pressure flows into the first pneumatic supply line (a) through the drain valve (1) and maintains the pressure inside the water supply tank (not shown) above a predetermined value. The stored water is continuously supplied through the shutoff cock 11, but after the operation of the railway vehicle is finished, when the driver presses the drain valve 1, the pneumatic pressure flows into the second pneumatic supply line (b) to drain the water supply tank. Since the receiving solenoid valve (not shown) is opened, the residual water in the water supply tank and the water supply line is discharged to the outside, and the residual cleaning water indicated by a on FIG. 2 is not drained properly. It is repeated several times to discharge the residual washing water of the washing water supply unit.

그러나, 상기 종래 기술에 따르면, 철도차량의 운행 종료시 화장실 세정수 공급부의 잔류 세정수를 자동적으로 배출시켜주는 배수장치가 마련되지 못하여, 작업자가 수작업으로 세정수 공급부의 잔류 세정수를 별도로 제거해야되는 번거로움이 있고, 이와 같이 한다고 하더라도 세정수 공급부에 잔류된 세정수가 제대로 배출되지 못한다.However, according to the prior art, a drainage system for automatically discharging the residual washing water of the toilet washing water supply unit at the end of the operation of the railway vehicle is not provided, and an operator must manually remove the residual washing water of the washing water supply unit. There is a hassle, and even in this case, the washing water remaining in the washing water supply unit is not properly discharged.

즉, 잔류 세정수의 제거작업을 별도로 수행해야하는 번거로움에 작업자의 편이성이 크게 저하되고, 또한 잔류 세정수의 배출이 제대로 이루어지지 못하여 세정수 공급부가 빈번하게 동파되는 문제가 발생 되었다.That is, the operator's convenience is greatly reduced due to the trouble of separately performing the removal of the residual washing water, and the washing water supply part frequently freezes because the residual washing water is not discharged properly.

한편, 종래 진공식 화장실 유니트에는 주위의 온도를 감지하여 온도가 강하 할 경우 세정수 공급부의 잔류 세정수를 자동으로 배수시키고, 이후로 화장실이 동작하지 않도록 하는 장치가 구비되어, 철도차량의 운행시는 세정수 공급부의 동파가 방지되고 있지만, 이러한 배수 작동 제어장치는 철도차량의 운행이 종료되어 전원이 차단되면 작동되지 않으므로 그 기능이 상실된다.On the other hand, the conventional vacuum toilet unit is equipped with a device for detecting the ambient temperature and automatically drains the residual washing water in the washing water supply unit when the temperature drops, and prevents the toilet from operating thereafter, Although the freezing of the washing water supply unit is prevented, this drainage operation control device is not operated when the power is cut off after the operation of the railway vehicle is lost its function.

이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 점검자가 배수밸브를 작동하게 되면 세정수 공급부에 남아있는 잔류수가 모두 변기쪽으로 배츨되어 동절기시 잔류 세정수에 의한 동파가 방지되도록 하는 철도차량용 진공식 화장실의 배수장치를 제공함에 그 목적이 있다.Therefore, the present invention has been invented to solve the above conventional problems, when the inspector operates the drain valve, all remaining water remaining in the washing water supply unit is discharged toward the toilet to prevent freezing by residual washing water during the winter season. Its purpose is to provide a drainage system for a vacuum toilet for railway vehicles.

제1도는 본 발명에 따른 철도차량용 진공식 화장실의 배수장치를 나타낸 전체 회로구성도이다.1 is an overall circuit diagram showing the drainage of the vacuum toilet for a railway vehicle according to the present invention.

이에 따르면, 세정수 공급부(a)의 정비 등으로 인하여 세정수 공급부(a)로 공급되는 세정수를 수작업으로 차단하도록 된 차단코크(11)가 급수라인측 세정수 공급라인에 설치되는, 이후 세정수 공급라인에 공급전자밸브(6)·제1역지밸브(8a)·급수가압기(4)·제2역지밸브(8b)·세정전자밸브(7)가 순차적으로 설치되고, 급수가압기(4)에 가압전자밸브(2)가 공급라인으로 연결되며, 또한 공급전자밸브(6)와 제1역지밸브(8a) 사이에 세정수 리턴라인이 연결되고, 이 리턴라인에 배수전자밸브(10)가 설치되며, 상기 각각의 전자밸브(2,6,7,10)는 각각 제어유니트(3)에 연결되고, 이 제어유니트(3)에는 배수밸브(1)의 배수제어상태를 감지하는 배수밸브작동감지수단인 압력스위치(9)가 연결되어 있다.According to this, the blocking coke 11 is installed in the washing water supply line on the water supply line side so as to manually block the washing water supplied to the washing water supply unit a due to maintenance of the washing water supply unit a. The supply solenoid valve 6, the 1st check valve 8a, the water supply pressurizer 4, the 2nd check valve 8b, and the washing solenoid valve 7 are sequentially installed in a water supply line, and a water supply pressurizer 4 is provided. A pressurized solenoid valve 2 is connected to the supply line, and a washing water return line is connected between the supply solenoid valve 6 and the first check valve 8a, and a drain solenoid valve 10 is connected to the return line. And each of the solenoid valves 2, 6, 7, and 10 is connected to a control unit 3, and the control unit 3 operates a drain valve for sensing a drainage control state of the drain valve 1. The pressure switch 9, which is a sensing means, is connected.

한편, 상기 압력스위치(9)는 배수밸브(1)의 제2공압 공급라인(b)에 연결되며, 상기 제어유니트(3)에는 세정버튼(도시안됨)이 연결된다.On the other hand, the pressure switch 9 is connected to the second pneumatic supply line (b) of the drain valve 1, the control unit 3 is connected to the washing button (not shown).

상기 본 발명은 철도차량 운행시(배수밸브(1)의 미조작시)에는 상기 종래 기술에서 연급한 바와 동일하게 작동되므로 그 설명을 생략하고, 이하 철도차량의 운행이 종료된 후 배수밸브(1)의 작동에 의한 배수제어상태를 설명한다.In the present invention, when the railroad vehicle is operated (when not operating the drainage valve 1), the same operation as that described in the related art is omitted, and thus the description thereof is omitted, and after the operation of the railroad vehicle is finished, the drainage valve 1 The following describes the drainage control state by the operation of.

철도차량의 운행이 종료되어 작업자가 배수밸브(1)를 누르게 되면, 배수밸브(1)에 연결된 공압 공급라인이 a에서 b로 변동되어, 제2공압 공급라인(b)에 의해 작동제어되는 급수탱크(도시안됨)의 배수용 전자밸브(도시안됨)가 열려져서 급수탱크 및 급수라인의 잔류수가 배수된다.When the operation of the railway vehicle is finished and the operator presses the drain valve 1, the pneumatic supply line connected to the drain valve 1 is changed from a to b, so that the water supply operated and controlled by the second pneumatic supply line b The solenoid valve (not shown) for the drainage of the tank (not shown) is opened to drain the remaining water from the water supply tank and the water supply line.

이와 같이 배수밸브(1)의 조작에 의해 공압라인이 변동되면 이는 압력스위치(9)에 감지되고, 압력스위치(9)의 감지신호가 제어유니트(3)에 입력되면 제어유니트(3)에서 1차적으로 공급전자밸브(6)를 닫고 배수전자밸브(10)를 열어, 세정수의 공급을 차단하고 공급전자밸브(6)와 제1차역지밸브(8a) 사이의 세정수를 세정수 리턴라인으로 배출 한다.When the pneumatic line is changed by the operation of the drain valve 1 as described above, this is sensed by the pressure switch 9, and when the detection signal of the pressure switch 9 is input to the control unit 3, the control unit 3 receives 1. By closing the supply solenoid valve 6 and opening the drain solenoid valve 10, the supply of the washing water is cut off and the washing water between the supply solenoid valve 6 and the first secondary check valve 8a is removed. To be discharged.

이후 물탱크의 압력이 대기압 수준으로 되는 시간(약 1분)이 경과되면, 제어유니트(3)에서 2차적으로 가압전자밸브(2)를 제어하여 급수가압기(4)에 의한 세정수의 가압이 수회 반복되도록 하면서, 세정전자밸브(7)를 수회 반복적으로 개폐시켜서 세정수 공급라인에 잔류된 세정수를 변기(5)로 배출시키는데, 이러한 작동 중에는 급수가압기(4)의 동작에 의해서 배수전자밸브(10)의 세정수 리턴라인으로부터 급수탱크로부터의 대기중의 공기가 유입되므로, 동작이 완료되면 세정수 공급라인에는 공기만이 채워지게 된다.After a time (about 1 minute) at which the pressure of the water tank reaches the atmospheric pressure level, the control unit 3 secondaryly controls the pressure solenoid valve 2 to pressurize the washing water by the water supply pressurizer 4. The washing solenoid valve 7 is repeatedly opened and closed several times while discharging the washing water remaining in the washing water supply line to the toilet 5 while being repeated several times. During this operation, the drain solenoid valve is operated by the operation of the water supply pressurizer 4. Since air in the atmosphere from the water supply tank flows from the washing water return line of (10), only the air is filled in the washing water supply line when the operation is completed.

한편, 상기 압력스위치(9)는 배수밸브 작동감지수단의 일예로서, 상기에서 언급된 실시예에 한정되지 않고 다양한 형태로 변경 실시될 수 있는데, 다른 일예로는, 배수밸브(1)에 자체 구비되어 공압 공급라인(a,b)의 변동에 따라 접지/단락되는 전기적인 접점이 될 수 있으며, 이러한 경우 그 구조를 더욱 단순화 할 수 있다.On the other hand, the pressure switch 9 is an example of the drain valve operation detecting means, and is not limited to the above-mentioned embodiment can be modified in various forms, as another example, the drain valve 1 is provided with itself It can be an electrical contact that is grounded / shorted according to the fluctuation of the pneumatic supply line (a, b), in this case it can be further simplified the structure.

상기와 같이 본 발명에 따르면, 철도차량이 운행 종료시 배수밸브의 작동에 따라 연동되어 화장실 세정수 공급부의 잔류 세정수가 자동적으로 배수되므로, 작업자의 배수작업이 편리해지고 빈번하게 발생되던 세정수 공급부의 동파가 방지되며, 배수작업 시간이 크게 단측되는 효과가 있다.As described above, according to the present invention, since the residual washing water of the toilet washing water supply unit is automatically drained by interlocking with the operation of the drain valve at the end of the operation of the railway vehicle, the drainage operation of the operator is convenient and the freezing frequency of the washing water supply unit is frequently generated. This is prevented, and the drainage work time is greatly shortened.
