Description

절수형 전자변기{Automatic toilet bowl with water saving feature}Automatic toilet bowl with water saving feature

본 고안은 변기에 관한 것으로, 특히 개폐판의 여닫힘에 의해 변기내의 물과 오물이 배출되도록 하는 변기에 있어서, 변기내의 수위를 감지하여 항상 적절한 수위를 유지하도록 하도록 함과 아울러 절수를 하도록 하는 절수형 전자변기에 관한 것이다.The present invention relates to a toilet, and in particular, in a toilet in which water and dirt in the toilet are discharged by opening and closing of the opening and closing plate, a section for detecting water level in the toilet to maintain an appropriate level at all times and saving water. It relates to a male electronic toilet.

대부분의 변기에는 물과 오물을 외부로 배출하면서 역류를 방지하기 위해 사이폰이 적용되는데, 이러한 사이폰관을 이용하는 경우 변기세정을 위한 많은 물이 필요하게 되며, 물과 오물을 배출할 때 그 구조에 의하여 큰 소음이 발생하게 된다.Most toilets use siphon to prevent backflow while draining water and dirt to the outside. When using these siphon tubes, a lot of water is required for flushing toilets. This will cause a loud noise.

이러한 문제점을 해결하기 위하여 본 출원인은 공개특허 10-2003-84334호에서 사이폰관을 사용하지 않고, 변기의 배출구에 개폐판을 두어 소량의 물로서 변기를 세정함과 아울러 배출소음이 작은 절수형 변기를 제안한 바 있다.In order to solve this problem, the present applicant does not use a siphon tube in Korean Patent Publication No. 10-2003-84334, and puts an opening and closing plate at the outlet of the toilet to clean the toilet with a small amount of water and a low-noise toilet with low discharge noise. Has been proposed.

그런데, 이러한 본 출원인이 제안한 절수형 변기는 유입되는 물의 수압에 의 해 조절밸브가 동작하여 피스톤을 구동시키고, 피스톤의 동작에 의해 랙기어가 이동하여 배출구를 개폐판이 여닫도록 하는 구조를 갖는데, 이러한 구조는 변기의 내측에서 설치되는 구조로서, 매우 복잡하고, 부품의 수도 많아서 제조비용의 증가를 가져온다.By the way, the water-saving toilet proposed by the present applicant has a structure in which the control valve is driven by the water pressure of the incoming water to drive the piston, and the rack gear is moved by the operation of the piston to open and close the opening and closing plate. The structure is a structure installed inside the toilet, and is very complicated, and the number of parts is large, resulting in an increase in manufacturing cost.

또한 물을 배출하기 위한 개폐판을 조절밸브와 연결된 누름밸브에 의해서 수동으로 동작시키는 구조로서 전자화 및 자동화되어가는 변기의 구조에 역행함으로써 부가가치가 낮으며, 또한 고급화에 한계가 있다.In addition, as a structure that manually operates the opening and closing plate for discharging water by the push valve connected to the control valve, the added value is low, and there is a limit to the high-grade by reversing the structure of the toilet being automated and automated.

따라서, 본 고안은 종래의 이러한 문제점을 감안하여, 변기의 배수와 수위유지를 전자화하기 위해 변기의 내측에 수위감지센서를 높낮이를 달리하여 설치하고, 급수 및 배수를 마이콤에 의해 제어함으로써 항상 일정한 수위 유지와 함께 최소한의 물로 변기의 세정이 가능하도록 한 절수형 전자변기를 제공하는데 그 목적이 있다.Therefore, the present invention, in view of the above problems in the prior art, by installing the water level sensor at different heights to the inside of the toilet in order to electronically maintain the drainage and level maintenance of the toilet, by controlling the water supply and drainage by a microcomputer always a constant water level It is an object of the present invention to provide a water-saving electronic toilet which allows cleaning of the toilet with a minimum of water together with fats and oils.

또한, 상기 변기의 내측 벽면에는 상하 길이방향으로 센서홀이 일체로 형성되고, 그 센서홀의 하측은 변기의 내측과 연통되어 변기내의 수위와 동일한 수위가 유지되도록 유입구가 형성되어 있으며, 센서홀의 내측에 수위감지센서들이 높낮이가 다르게 설치된다.In addition, a sensor hole is integrally formed on the inner wall surface of the toilet in the vertical direction, and a lower side of the sensor hole communicates with the inside of the toilet to form an inlet to maintain the same level as the level in the toilet. Level sensors are installed differently in height.

이와같이 구성되는 본 고안은 수위를 유지하도록 하는 구조와 물내림 등의 구조가 전자화되어 구조가 간단하고, 부가가치가 높으며, 아울러 전자화에 따른 다양한 기능을 부가할 수 있어 고급화에 적합한 효과가 있다.The present invention constituted as described above has a structure that maintains the water level and the structure such as flushing is electronic, so that the structure is simple, the added value is high, and it is possible to add various functions according to the electronic, which is suitable for high-end.

이와 같은 구조를 갖는 본 고안을 첨부한 도면을 참조하여 상세히 설명한다.The present invention having such a structure will be described in detail with reference to the accompanying drawings.

도1은 본 고안의 구조를 보인 도이고, 도2는 동작상태를 설명하기 위한 도이며, 도3은 본 고안을 제어하기 위한 제어 블럭도를 보인 도이다.1 is a view showing the structure of the present invention, Figure 2 is a view for explaining the operating state, Figure 3 is a view showing a control block diagram for controlling the present invention.

도1에서와 같이 본 고안은, 변기(100)의 내측 상단둘레를 따라서 물을 급수하기 위한 급수노즐(121)이 형성되며, 이 급수노즐(121)은 급수관(110)에 연결되어 세정수를 외부로부터 공급받아 물을 담수하게 된다.As shown in FIG. 1, the present invention provides a water supply nozzle 121 for supplying water along the inner upper circumference of the toilet 100, and the water supply nozzle 121 is connected to the water supply pipe 110 to clean the water. Fresh water is supplied from the outside.

급수관(120)에는 마이콤(190)의 제어를 받아 급수관로를 개폐하는 전자식 급수밸브(120)가 설치되어 있으며, 변기(100)의 하측에는 물과 오물을 배출관(140)을 통해 외부로 배출하기 위한 배출구(130)가 형성되어 있다.The water supply pipe 120 is provided with an electronic water supply valve 120 that opens and closes the water supply line under the control of the microcomputer 190, and discharges water and dirt to the outside through the discharge pipe 140 at the lower side of the toilet 100. The outlet 130 is formed.

배출구(130)는 개폐판(170)에 의해 개폐되어 물과 오물을 외부로 배출하며, 이때 개폐판(170)은 후방에 개폐레버(183)가 회전가능하도록 결합되어 모터(180)의 정회전 및 역회전에 의해 개폐판(170)이 개폐된다.The outlet 130 is opened and closed by the opening and closing plate 170 to discharge water and dirt to the outside, the opening and closing plate 170 is coupled to the rear opening and closing lever 183 rotatably in the forward rotation of the motor 180 And the opening and closing plate 170 is opened and closed by the reverse rotation.

이를 위해 모터(180)의 축(181)에는 회전판(182)이 장착되어 있으며. 그 회전판(182)의 가장자리로는 개폐레버(183)의 일단이 편심되게 장착됨과 아울러 개폐레버(183)의 타단이 개폐판(170)의 후방에 회전가능하도록 결합된다.To this end, the rotating plate 182 is mounted on the shaft 181 of the motor 180. One end of the opening and closing lever 183 is eccentrically mounted to the edge of the rotating plate 182, and the other end of the opening and closing lever 183 is rotatably coupled to the rear of the opening and closing plate 170.

변기(100)의 내측으로는 수위를 감지하기 위한 수위감지센서들(161,162,163)이 상하방향으로 높낮이를 달리하여 장착되며, 이 수위감지센서들(161,162,163)이 변기의 내측에서 노출되어 보이는 것과 오물이 유착되어 수위감지능력을 상실하는 것을 막기위해 변기(100)의 내측 후면에 상하방향으로 하부가 개방된 유입구(151)를 갖는 센서홀(150)을 형성한 다음, 그 센서홀(150)의 내측에 상하방향으로 높낮이를 달리한 다수개의 수위감지센서들(161,162,163)을 장착함이 바람직하다.Inside the toilet 100, water level sensors 161, 162 and 163 for detecting the water level are mounted at different heights in the vertical direction. In order to prevent the loss of water level sensing ability to form a sensor hole 150 having an inlet 151 with a lower opening in the vertical direction on the inner rear of the toilet 100, and then the inner side of the sensor hole 150 It is preferable to mount a plurality of water level detection sensors (161, 162, 163) having different heights in the vertical direction.

센서홀(150)의 내측으로 유입구(151)를 통해 물이 유입되며, 대기압에 의해 변기(100) 내측의 수위와 동일하게 수위가 형성됨으로써 수위감지센서들(161,162,163)은 이 센서홀(150)의 수위를 감지함으로써 변기(100) 내측의 수위를 알 수 있는 것이다.Water is introduced into the sensor hole 150 through the inlet 151, and the water level is formed in the same manner as the water level inside the toilet 100 by atmospheric pressure, so that the water level detection sensors 161, 162, and 163 have the sensor hole 150. By detecting the water level of the toilet 100 will be able to know the level.

한편, 도1에서는 좌대(200)의 하단에는 전자센서(191)를 부착하여 사용자의 변기 사용유무를 자동으로 판단하게 되는데, 이때 전자센서(191)는 압력센서로서 사용자가 변기 사용 후 일어서면, 마이콤(190)이 이의 신호를 입력받아 물과 오물을 배출하도록 제어할 수 있고, 다른 방안으로는 전자센서(191)를 버튼타입으로 하 여 변기의 외측부에 부착함으로써 사용자가 버튼을 누르면 마이콤(190)이 물과 오물을 배출하도록 제어할 수 있다.Meanwhile, in FIG. 1, an electronic sensor 191 is attached to the lower end of the pedestal 200 to automatically determine whether the toilet is used by the user. In this case, the electronic sensor 191 is a pressure sensor. The microcomputer 190 may be controlled to discharge water and dirt by receiving a signal thereof. Alternatively, the microcomputer 190 may be attached to the outer side of the toilet by using the electronic sensor 191 as a button type. ) Can be controlled to discharge water and dirt.

이러한 구조를 갖는 본 고안의 동작상태를 설명한다.It describes the operating state of the present invention having such a structure.

마이콤(190)은 초기상태를 도1과 같이 제2수위센서(162)의 위치에서 수위가 유지되도록 하고, 사용자가 변기를 사용 후에 일어서거나 또는 물내림 버튼을 누르게 되면, 마이콤(190)은 전자센서(191)로부터 신호를 입력받아 전자식 급수밸브(120)를 열어서 물을 급수함과 동시에 모터(180)를 정회전시켜 개폐판(170)을 열어 변기(100)내의 물과 오물을 배출관(140)으로 배출하게 된다.The microcomputer 190 maintains an initial state at the position of the second water level sensor 162 as shown in FIG. 1, and when the user stands up after using the toilet or presses the water down button, the microcomputer 190 displays an electronic state. In response to a signal from the sensor 191, the electronic water supply valve 120 is opened to supply water, and at the same time, the motor 180 is rotated forward to open the opening and closing plate 170 to discharge water and dirt in the toilet 100. Will be discharged.

물과 오물이 배출되면서 제3수위감지센서(163)의 위치보다 수위가 낮아지면, 마이콤(190)은 모터(180)를 역회전시켜 개폐판(170)이 배출구(130)를 닫도록 하여 변기(100)내의 수위가 높아지도록 하며, 수위가 제2수위감지센서(162)에 다다르면 전자식 급수밸브(120)를 닫아서 급수를 중단하게 된다.When the water level is lower than the position of the third water level sensor 163 while the water and dirt is discharged, the microcomputer 190 reversely rotates the motor 180 so that the opening and closing plate 170 closes the outlet 130. The water level in the 100 is increased, and when the water level reaches the second water level sensor 162, the water supply is stopped by closing the electronic water supply valve 120.

한편, 허드렛물 등을 변기(100)에 버리게 되면, 수위가 증가하므로 제1수위감지센서(161)로부터 감지신호가 입력되고, 이에따라 마이콤(190)은 모터(180)를 제어하여 개폐판(170)을 열어 물을 배수함으로써 수위를 낮추게 되며, 그 낮아지는 수위가 제2감지센서(162)에 다다르면 다시 모터(180)를 제어하여 개폐판(170)을 닫도록 함으로써 일정한 수위가 유지되도록 한다. On the other hand, if the waste water is discarded in the toilet 100, the water level is increased, so that the detection signal is input from the first water level sensor 161, accordingly, the microcomputer 190 controls the motor 180 to open and close the plate 170 The water level is lowered by opening the water) and the water level is lowered. When the water level reaches the second detection sensor 162, the water level is maintained by controlling the motor 180 to close the opening and closing plate 170 again.
