Description

초음파 세척기의 가드 결합 구조 진동자 조립체 및 이를 포함하는 초음파 세척기Guard coupling structure vibrator assembly of ultrasonic cleaner and ultrasonic cleaner including the same
본 발명의 실시예는 초음파 세척기의 가드 결합 구조 진동자 조립체 및 이를 포함하는 초음파 세척기에 관한 것이다. An embodiment of the present invention relates to a vibrator assembly having a guard coupled structure for an ultrasonic cleaner and an ultrasonic cleaner including the same.
초음파 진동자는 전원을 공급받아 초음파 주파수대의 진동을 일으키는 장치이다. 초음파 진동자는 세척기, 피부 안마기, 칫솔 등과 같은 다양한 장치에 이용되며, 진동에 의한 세척 효과를 발휘한다.An ultrasonic vibrator is a device that receives power and generates vibration in an ultrasonic frequency band. Ultrasonic vibrators are used in various devices such as washing machines, skin massagers, toothbrushes, and the like, and exhibit cleaning effects by vibration.
초음파 진동자는 전원의 인가 시 전기적 신호를 기계적인 초음파 진동으로 변환하여 내부에 전달하는 기능을 담당한다. 예를 들어, 초음파 진동자의 내부에는 압전소자(Piezo electric element)가 구비되며, 압전소자에서 발생된 진동이 전달될 수 있다. The ultrasonic vibrator converts electrical signals into mechanical ultrasonic vibrations when power is applied and transmits them to the inside. For example, a piezoelectric element is provided inside the ultrasonic vibrator, and vibration generated by the piezoelectric element can be transmitted.
압전소자가 적용된 초음파 진동자 중에서 세척기 분야에는 란쥬반형 진동자가 주로 이용되고 있다. 란쥬반형 진동자는 압전소자에 금속재를 부착하여 진동을 확대하는 구조로 이루어져 있다. 란쥬반형 진동자는 원판형 압전소자에서 발생하는 반경 방향의 진동을 압전소자의 양면에 부착한 금속을 통해 종 방향의 진동으로 변환 및 확대하여 내부로 진동을 전달한다. Among ultrasonic vibrators to which a piezoelectric element is applied, a Ranjuvan-type vibrator is mainly used in the washing machine field. The Ranjuvan type vibrator has a structure that expands vibration by attaching a metal material to a piezoelectric element. The Ranjuvan-type vibrator converts and expands vibration in the longitudinal direction through metal attached to both sides of the piezoelectric element in the radial direction generated by the disc-shaped piezoelectric element, and transfers the vibration to the inside.
한편, 진동자가 결합된 세척기의 구조는 주로 수조의 바닥에 진동자의 상면이 노출되도록 결합된다. 그리고 진동자의 진동은 수조로 전달되며, 수조에 담긴 피세척물(예: 식기 등)은 세척될 수 있다. On the other hand, the structure of the washing machine coupled with the vibrator is mainly coupled to the bottom of the water tank so that the upper surface of the vibrator is exposed. Vibration of the vibrator is transmitted to the water tank, and objects to be washed (eg, dishes, etc.) contained in the water tank can be washed.
그런데, 이와 같이 진동자의 상면이 수조의 바닥을 통해 외부로 노출되는 구조로 이루어짐에 따라, 수조에 담긴 피세척물(예: 식기 등)이 진동자의 상면과 물리적으로 접촉하게 될 경우 피세척물(예: 식기 등)의 파손 및 손상을 유발하는 문제가 발생될 수 있다. However, as the upper surface of the vibrator is configured to be exposed to the outside through the bottom of the water tank, when the object to be washed (eg, tableware) contained in the water tank physically contacts the upper surface of the vibrator ( Ex: tableware, etc.) may cause problems that cause breakage or damage.
본 발명과 관련된 선행문헌으로서, 대한민국 등록특허공보 제10-1648710호(2016.08.17. 공고일)에는 초음파 세척기의 진동자 결합 어셈블리가 개시되어 있다. 다만, 종래의 선행문헌에 따르면 식기 등이 수조 내에서 진동자와 물리적으로 접촉하는 것을 방지하는 가드 구조에 관하여 전혀 제시하고 있지 않다.As a prior document related to the present invention, Korean Patent Registration No. 10-1648710 (2016.08.17. Publication date) discloses a vibrator coupling assembly of an ultrasonic cleaner. However, according to prior literature, there is no suggestion of a guard structure that prevents dishes or the like from physically contacting the vibrator in the water tank.
본 발명의 목적은, 식기 등의 피세척물이 수조 내에서 진동자와 물리적으로 접촉하는 것을 방지하여, 식기 등의 피세척물의 파손 및 손상 그리고 소음을 방지할 수 있는 가드 구조를 구비한 초음파 세척기의 가드 결합 구조 진동자 조립체를 제공하는 것이다. An object of the present invention is to prevent objects to be washed, such as tableware, from physically contacting a vibrator in a water tank, to provide an ultrasonic cleaner having a guard structure capable of preventing damage and noise of objects to be washed, such as tableware and the like. It is to provide a vibrator assembly with a guard coupling structure.
본 발명의 다른 목적은, 식기 등의 피세척물이 수조 내에서 진동자와 물리적으로 접촉하는 것을 방지하여, 식기 등의 피세척물의 파손 및 손상을 방지할 수 있는 초음파 세척기를 제공하는 것이다. Another object of the present invention is to provide an ultrasonic cleaner capable of preventing objects to be washed, such as tableware, from physically contacting a vibrator in a water tank, thereby preventing breakage and damage to objects to be washed, such as tableware.

The top of the housing 200 is open, and the curved portion 111 located on the top of the vibrator 110 may be exposed to the outside through the bottom of the water tank 10 through the top opening of the housing 200 . Accordingly, the vibration transmitted from the vibrator 110 may be transmitted to the inside of the water tank 10.
구체적인 예로서, 하우징(200)은 제1 하우징부(210), 제2 하우징부(220), 제3 하우징부(230)를 포함할 수 있다(도 1 내지 도 4 참조). As a specific example, the housing 200 may include a first housing part 210, a second housing part 220, and a third housing part 230 (see FIGS. 1 to 4).
제1 하우징부(210)은 상기 진동자(100)가 내부 중심을 따라 길이 방향으로 관통 배치되는 제1 중공부(215)를 구비하며 원형 관 형상을 가질 수 있다. The first housing part 210 may include a first hollow part 215 through which the vibrator 100 is penetrating along an inner center in a longitudinal direction and may have a circular tubular shape.
제2 하우징부(220)는 상기 제1 중공부(215)의 하단을 통해 삽입되며 상기 연장부(115)의 직경보다 크고 상기 날개부(113)의 직경보다 작은 제2 중공부(225)를 구비하며, 상기 제1 하우징부(210)의 하부에 나사 체결될 수 있다. The second housing part 220 is inserted through the lower end of the first hollow part 215 and has a second hollow part 225 that is larger than the diameter of the extension part 115 and smaller than the diameter of the wing part 113. It is provided and can be screwed to the lower part of the first housing part 210.
제3 하우징부(230)은 상기 제1 하우징부(210)의 외주 면을 감싸도록 체결되는데, 수조(10)의 바닥에 형성된 홀을 통해 밀봉 결합될 수 있다. The third housing part 230 is fastened to surround the outer circumferential surface of the first housing part 210, and can be sealed through a hole formed at the bottom of the water tank 10.
바람직하게는 제1 하우징부(210)는 확관부(211), 및 환형 돌출부(213)를 포함한다. Preferably, the first housing portion 210 includes an expansion tube 211 and an annular protrusion 213 .
확관부(211)는 제1 중공부(215)의 상단에 위치하는 원추 형상의 관 개방 부위를 말한다. 확관부(211)는 상단 개방 부위로 갈수록 제1 중공부(215)의 직경이 점진적으로 확장 형성되는 원추 형상을 갖는다. The expansion tube 211 refers to a cone-shaped tube opening portion located at an upper end of the first hollow portion 215 . The expansion tube 211 has a conical shape in which the diameter of the first hollow part 215 gradually expands toward the top open portion.
환형 돌출부(213)는 확관부(211)의 하단에 위치하는데, 제1 중공부(215)의 반경 방향으로 직경이 축소되는 환형 띠 형상을 갖도록 돌출된다. The annular protrusion 213 is located at the lower end of the expansion tube 211 and protrudes in a radial direction of the first hollow part 215 to have an annular band shape in which the diameter is reduced.
환형 돌출부(213)는 제1 하우징부(210)의 제1 중공부(215)의 하부를 통해 제2 하우징부(220)가 삽입될 때, 제2 하우징부(220)의 상단과 밀착되는 부분으로서, 제2 하우징부(220)의 체결 거리를 제한한다. 환형 돌출부(213)의 축소된 직경은 제2 중공부(225)의 직경에 대응하는 크기를 가질 수 있다.When the second housing part 220 is inserted through the lower part of the first hollow part 215 of the first housing part 210, the annular protrusion part 213 comes into close contact with the upper end of the second housing part 220. As, the fastening distance of the second housing part 220 is limited. The reduced diameter of the annular protrusion 213 may have a size corresponding to the diameter of the second hollow part 225 .

Meanwhile, when the vibrator 100 is through-coupled to the center of the housing 200, the curved portion 111 should be disposed at a position lower than the upper end of the expansion tube 211. Accordingly, a height difference may occur between the curved portion 111 positioned at the upper end of the vibrating body 110 and the guard structure 300 installed on the expansion pipe 211 . In addition, as the height difference between the curved portion 111 and the expansion pipe 211 is maintained, objects to be washed, such as tableware, contained in the water tank 10 are prevented from directly contacting the curved portion 111 of the vibrator 110. It can be.
한편, 제2 하우징부(220)의 상부에는 적어도 하나의 씰링부(221)가 배치될 수 있다(도 8 참조). 씰링부(221)는 원형 돌출부(213)의 하부와 제2 하우징부(220)의 상부 사이에 개재되어 진동자(110)와 제1, 2 하우징부(210, 220) 간의 결합 부위를 통해 발생되는 틈새를 밀봉하여 수밀 효과를 강화시킬 수 있다 Meanwhile, at least one sealing part 221 may be disposed above the second housing part 220 (see FIG. 8 ).

The gap can be sealed to enhance the watertight effect.
가드 구조물(300)Guard Structure (300)
가드 구조물(300)은 상기 하우징(200)의 상단에 착탈 결합 또는 고정된다. The guard structure 300 is detachably coupled or fixed to the top of the housing 200 .
예를 들어, 가드 구조물(300)은 하우징(200)의 상단 개방부위를 통해 볼록하게 아치 형상으로 설치될 수 있다. 이에 따라, 수조(10)에 담긴 피세척물이 세척 과정 중에 진동체(110)의 곡면부(111)와 물리적으로 접촉되는 것이 방지될 수 있다. 이로 인해, 식기 등의 피세척물의 파손 및 손상을 방지할 수 있다 For example, the guard structure 300 may be convexly installed in an arch shape through an upper open portion of the housing 200 . Accordingly, it can be prevented from physically contacting the curved portion 111 of the vibrator 110 during the cleaning process with the object to be washed contained in the water tub 10 . As a result, it is possible to prevent breakage and damage to objects to be washed, such as tableware.
만일, 가드 구조물(300)이 없다면 수조(10)에 담긴 피세척물, 예를 들어 식기 등은 진동을 전달하는 진동체(110)의 곡면부(111)에 접촉되어 강한 초음파 진동에 의해 손상을 입거나 파손될 가능성이 있다. If there is no guard structure 300, objects to be washed, such as dishes, contained in the water tank 10 are damaged by strong ultrasonic vibration in contact with the curved portion 111 of the vibrator 110 that transmits the vibration. There is a possibility of wear or damage.
따라서, 가드 구조물(300)은 확관부(211)의 상단보다 설정 거리를 두고 높은 위치에 형성되는 것이 바람직하다. 이로써, 가드 구조물(300)이 곡면부(111)와 수조(10) 내의 피세척물 간의 접촉을 막아 피세척물의 파손 및 손상을 방지할 수 있다. Therefore, the guard structure 300 is preferably formed at a higher position than the upper end of the expansion tube 211 at a set distance. As a result, the guard structure 300 prevents contact between the curved portion 111 and the object to be washed in the water tub 10, thereby preventing breakage and damage of the object to be washed.

Vibration of the vibrating body 110 can be spread to a wider range into the inside of the water tank via the expansion rubber ring 240 . According to this configuration, it is possible to expect an effect of improving the washing power by increasing the vibration generation range in the water tank.
또한, 가드 구조물(300)이 확관 고무 링(240)과 함께 하우징(200)에서 분리 교체 가능한 구조로 이루어짐에 따라 오염 또는 손상 시 신품으로 손쉽게 교체할 수 있으며, 용도에 따라 준비된 다양한 형상 및 크기를 갖는 가드 구조물(300)로 변경하여 교체 사용이 가능한 장점이 있다. In addition, as the guard structure 300 is made of a structure that can be separated and replaced from the housing 200 together with the expansion rubber ring 240, it can be easily replaced with a new product in case of contamination or damage, and various shapes and sizes prepared according to the purpose.
