일반적으로 가습기는 제1도에 도시된 바와 같이 상부에 물받이(2)가 설치된 본체(1)와 물받이(2)에 놓이는 물통(6) 및 무화관(8)으로 구성된다. 한편 물통(6)은 저면 일측으로 물받이(2)에 돌출된 돌기(2a)에 눌려 물이 간헐적으로 유출되는 급수구(7)가 마련되고 본체(1)의 상부 일측에 물통(6)의 물이 담수되는 가습실(5)이 마련된다. 또한 가습실(5)에는 담수된 물을 진동으로 무화시키는 진동자(4)가 설치된다.In general, the humidifier is composed of a main body (1) with a drip tray (2) installed at the top, a bucket (6) placed on the drip tray (2) and an atomizing tube (8) as shown in FIG. Meanwhile, the bucket 6 is provided with a water supply port 7 through which water is intermittently flowed out by being pressed by the protrusion 2a protruding from the drip tray 2 toward the bottom of one side, and the water of the bucket 6 on the upper side of the main body 1. The humidification room 5 to which this fresh water is provided is provided. In addition, the humidifier (5) is provided with a vibrator (4) for atomizing the fresh water with vibration.

이처럼 구성된 종래의 가습기는 물통(6)의 물이 급수구(7)를 통하여 간헐적으로 물받이(2) 내부로 급수되고 또한 급수된 물은 가습실(5)에 설치된 진동자(4)에 의해 진동되어 수증기로 변한 상태에서 팬(3)에 의해 무화관(8)의 상단에 설치된 노즐(8a)을 통하여 실내로 방출되면서 가습된다.In the conventional humidifier configured as described above, the water in the bucket 6 is intermittently supplied into the drip tray 2 through the water inlet 7, and the water supplied is vibrated by the vibrator 4 installed in the humidification chamber 5. It is humidified while being discharged into the room through the nozzle 8a provided on the upper end of the atomizing pipe 8 by the fan 3 in the state changed into water vapor.

한편 가습실(5)의 일측에 수위를 감지하는 수위 감지장치가 설치된다. 즉 가습실(5)의 일측으로 안내기둥(1a)이 입설되고 안내기둥(1a)에는 내부에 최고수위를 감지하는 리드스위치(1b)와 최저 수위를 감지하는 리드스위치(1c)가 각각 내장된다. 그리고 안내기둥(1a)의 외주연에 자성체(1e)가 매설된 부구(1d)가 설치되어 수위에 따라 승강되면서 각 리드스위치(1b)(1c)를 작동시켜 수위를 감지하게 된다. 그러나 가습실(5)의 내부에 안내기둥(1a)과 송풍관(3a)이 별도로 설치됨으로 가습실(5)의 내부 공간이 좁아져 제작하기 어렵고 또한 가습실(5)의 내부를 청소하기 곤란한 등의 문제가 있다.On the other hand, the water level detection device for detecting the water level is installed on one side of the humidification chamber (5). That is, a guide pillar 1a is placed at one side of the humidification chamber 5, and a reed switch 1b for detecting the highest water level and a reed switch 1c for detecting the lowest water level are respectively built in the guide pillar 1a. . In addition, a buoy 1d in which the magnetic body 1e is embedded is installed at the outer circumference of the guide column 1a and ascends according to the water level, thereby operating the respective reed switches 1b and 1c to sense the water level. However, since the guide pillar 1a and the blower tube 3a are separately installed in the humidifying chamber 5, the internal space of the humidifying chamber 5 is narrowed, making it difficult to manufacture, and also difficult to clean the inside of the humidifying chamber 5. There is a problem.

본 고안은 종래의 문제점을 감안하여 개발된 것으로서, 본 고안의 목적은 가습실의 외측에 자성체의 접근에 따라 동작되는 스위치부재를 설치하고 또한 무화관에 자성체가 내장된 부구를 설치하여 가습실의 바닥공간이 넓어지도록 함으로서, 청소하기 편리하도록 한 가습기의 수위 감지장치를 제공함에 있다.The present invention was developed in view of the conventional problems, and an object of the present invention is to install a switch member that operates according to the approach of the magnetic material on the outside of the humidification chamber, and install a buoy with the magnetic material built in the atomizing pipe. By increasing the floor space, it is to provide a level sensor for the humidifier to facilitate the cleaning.

상기 목적을 달성하기 위하여 본 고안은 본체 상부의 가습실 내부로 급수된 물이 초음파 진동으로 무화되어 수증기로 변한 다음 상기 가습실의 상부에 놓인 무화관을 통하여 토출되는 것에 있어서, 상기 무화관의 내측에 형성되어 상기 가습실 바닥 쪽으로 연장 형성된 지주, 상기 지주에 끼워져 수위에 따라 승강되고 자성체가 내설된 부구, 그리고 상기 가습실의 외측 저면에 설치되어 상기 자성체의 자성력에 의해 온/오프되는 스위치부재를 구비하는 특징이 있다.In order to achieve the above object, the present invention is that the water supplied into the humidification chamber of the upper part of the main body is atomized by ultrasonic vibration and is converted into water vapor, and then discharged through the atomization pipe placed on the upper part of the humidification chamber. A support member formed in the support and extending toward the bottom of the humidification chamber, a buoy in which the support is mounted and lifted according to the water level, and a magnetic material is built in, and a switch member installed on the outer bottom of the humidification chamber to be turned on / off by the magnetic force of the magnetic material. It is characterized by having.

이하에서는 첨부도면을 참조하여 본 고안의 바람직한 실시예를 상세히 설명하면 다음과 같다.Hereinafter, a preferred embodiment of the present invention with reference to the accompanying drawings in detail as follows.

제2도는 본 고안 가습기의 단면도이다. 즉 본체(10)의 상부에 물받이(11)가 형성되고 또한 물받이(11)에는 물통(12)이 놓인다. 이때 물받이(11)의 상면에 형성된 돌기(11a)에 물통(12) 저면의 급수구(12a)가 놓이면 물통(12)의 물이 물받이(11)쪽으로 유출된다. 한편 본체(10)의 상부 일측으로 진동자(14)가 형성된 가습실(13)이 마련된다. 또한 가습실(13)의 직 상부에 무화관(16)이 놓이고 무화관(16)의 상단에 가습된 수증기를 실내로 토출시키는 노즐(16a)이 놓인다.2 is a cross-sectional view of the present invention humidifier. That is, the drip tray 11 is formed on the upper portion of the main body 10, and the bucket 12 is placed on the drip tray 11. At this time, when the water supply port 12a of the bottom surface of the water tank 12 is placed on the protrusion 11a formed on the top surface of the water receiver 11, the water of the water tank 12 flows out toward the water receiver 11. Meanwhile, a humidifying chamber 13 in which the vibrator 14 is formed is provided at one upper side of the main body 10. In addition, the atomizing pipe 16 is placed directly above the humidifying chamber 13, and a nozzle 16a for discharging the humidified water vapor into the room is placed at the top of the atomizing pipe 16.

또한 가습실(13)의 일측으로 송풍관(15a)이 형성되고 본체(10)의 내부에는 송풍관(15a)으로 바람을 송풍하는 팬(15)이 설치된다. 또한 무화관(16)의 내주면 일측으로 지주(21)가 형성되고 지주(21)에 자성체(23)가 내설된 부구(22)가 수위에 따라 승강 가능토록 설치된다. 한편 지주(21)와 대응토록 가습실(13)의 외측 저면으로 스위치부재(20)가 설치된다.In addition, a blower tube 15a is formed at one side of the humidifying chamber 13, and a fan 15 for blowing wind to the blower tube 15a is installed inside the main body 10. In addition, a support 21 is formed on one side of the inner circumferential surface of the atomizing pipe 16, and the support 22 having the magnetic body 23 embedded therein is installed to be able to move up and down according to the water level. On the other hand, the switch member 20 is installed on the outer bottom of the humidification chamber 13 so as to correspond to the support 21.

즉 스위치부재(20)는 가습실(13)의 외측 저면에 안내봉(24)이 형성되고 또한 안내봉(24)의 하단으로 고정단자(25)가 설치된다. 한편 안내봉(24)의 외주면에 끼워져 승강되는 이동단자(26)가 마련된다. 즉 각 단자(25)(26)에 전원이 인가된 상태에서 이동단자(26)의 자중에 의해 고정단자(25)와 접하면 가습실(13)이 최고수위가 된다. 또한 수위가 떨어져 부구(22)가 하강되면 이의 자성체(23)에 의해 이동단자(26)가 상승되면서 고정 단자(25)와 떨어지고 이때 최저 수위가 된다.That is, the switch member 20 has a guide rod 24 formed on the outer bottom surface of the humidification chamber 13, and a fixed terminal 25 is installed at the lower end of the guide rod 24. On the other hand, a mobile terminal 26 which is fitted on the outer circumferential surface of the guide rod 24 and is elevated is provided. That is, when the power is applied to each terminal 25, 26, the humidification chamber 13 becomes the highest level when it contacts the fixed terminal 25 by the weight of the mobile terminal 26. In addition, when the water level falls, the float 22 is lowered by the magnetic material 23, the mobile terminal 26 is raised and falls from the fixed terminal 25 and at this time becomes the lowest level.

이처럼 구성된 본 고안은 물통(12) 저면에 형성된 급수구(12a)가 물받이(11)에 돌출 형성된 돌기(11a)에 눌려 물받이(11)로 물이 유출되고 또한 유출된 물은 진동자(14)가 설치된 가습실(13)로 급수된다.The present invention configured as described above is the water supply port 12a formed on the bottom surface of the bucket 12 is pressed by the protrusion (11a) protruding in the drip tray 11, the water flows out into the drip tray 11, and the outflowed water is also a vibrator (14) Water is supplied to the installed humidification chamber 13.

한편 가습실(13)과 물받이(11)의 수위가 일치된 상태에서 급수구(12a) 저면까지 물이 차면 수압에 의해 급수구(12a)가 일시적으로 막히게 되고 또한 진동자(14)의 진동으로 수위가 떨어지면 급수구(12a)가 열리면서 물이 재차 공급되는 과정이 반복된다.On the other hand, when water reaches the bottom of the water inlet 12a while the water level of the humidifying chamber 13 and the water receiver 11 are in agreement, the water inlet 12a is temporarily blocked by the water pressure, and the water level is caused by the vibration of the vibrator 14. When is dropped, the water supply opening (12a) is opened and the process of supplying water again is repeated.

한편 물통(12)의 물이 가습실(13)내부로 공급되면 수위가 변하게 되고 이때 부구(22)가 수위에 따라 승강되면서 최고 수위와 최저 수위를 감지하게 된다. 즉 무화관(16)의 일측면에 형성된 지주(21)에 부구(22)가 결합된 상태에서 수위가 증가되면 상승된다. 이때 자성체(23)가 함께 상승되어 스위치부재(20)에서 멀어진다. 따라서 이동단자(26)가 자중에 의해 하강되어 고정단자(25)와 접하게 되고 이때 최고수위가 본체(10)의 외측으로 표시된다. 또한 수위가 떨어지면 부구(22)가 하강되고 이때 자성체(23)가 함께 하강되어 이동단자(26)가 자성력에 의해 상승된다. 한편 이동단자(26)가 상승되면 고정단자(25)와 떨어지면서 최저수위가 본체(10)의 외부로 표시된다. 또한 무화관(16)을 들어올리면 부구(22)와 지주(21)가 함께 들리기 때문에 가습실(13) 내부 공간이 넓게 확보되어 청소하기 편리하다.On the other hand, when the water in the bucket 12 is supplied into the humidification chamber 13, the water level is changed, and the float 22 is elevated according to the water level to detect the highest water level and the lowest water level. That is, when the water level is increased in the state in which the float 22 is coupled to the support 21 formed on one side of the atomizing pipe 16, it is raised. At this time, the magnetic body 23 is raised together to move away from the switch member (20). Therefore, the mobile terminal 26 is lowered by its own weight to come into contact with the fixed terminal 25, and the highest water level is displayed to the outside of the main body 10. In addition, when the water level falls, the float 22 is lowered at this time, the magnetic body 23 is lowered together, the mobile terminal 26 is raised by the magnetic force. Meanwhile, when the mobile terminal 26 is raised, the lowest water level is displayed to the outside of the main body 10 while falling from the fixed terminal 25. In addition, lifting the atomization pipe 16, because the float 22 and the support 21 is lifted together, the space inside the humidification chamber 13 is secured wide, it is convenient to clean.

이상에서와 같이 본 고안에 따르면 가습실의 외측으로 고정단자와 이동단자가 설치되고 가습실을 덮는 무화관의 내측에 수위에 따라 승강되는 부구가 설치된 상태에서 부구가 하강되면 자성체의 자성력에 의해 이동단자가 고정 단자와 떨어지면서 최저 수위가 표시됨으로 가습실의 내부 공간이 넓게 확보된다. 따라서 가습실의 바닥 청소가 편리한 효과가 있다.As described above, according to the present invention, when the fixed ball and the mobile terminal are installed outside the humidification chamber and the floating ball is lowered in accordance with the water level in the inside of the atomizing pipe covering the humidification chamber, the magnetic force of the magnetic material is lowered. As the moving terminal is separated from the fixed terminal, the minimum water level is displayed, thereby ensuring a wide space inside the humidification chamber. Therefore, the floor cleaning of the humidifying room has a convenient effect.
