본 발명은 세탁기에 관한 것으로서, 더욱 상세하게는 사용환경 및 운전조건에 따른 열에 의해 커넥터의 팽창 및 수축이 반복되더라도 로터와 하부베어링 사이 에 틈새가 발생하지 않도록 하여, 로터의 유격으로 인해 발생하던 운전시의 소음을 해소할 수 있도록 한 것이다.The present invention relates to a washing machine, and more particularly, to prevent a gap between the rotor and the lower bearing even when the connector is repeatedly expanded and contracted by heat according to the use environment and operating conditions, so that the driving occurred due to the play of the rotor. The noise of the city was to be eliminated.

일반적으로, 세탁기는 세제의 유화 작용 및 세탁날개의 회전에 따른 수류의 마찰작용 및 펄세이터가 세탁물에 가하는 충격작용 등을 이용하여 의복, 침구 등에 부착된 각종 오염물질을 제거하는 제품으로서, 센서에 의해 세탁물의 양과 종류를 감지하여 세탁방법을 자동으로 설정하고 또한 세탁수의 수위를 세탁물의 양과 종류에 따라 적절한 수위까지 급수한 후 마이콤의 제어를 받아 세탁을 수행하게된다.In general, a washing machine is a product that removes various contaminants attached to clothes, bedding, etc. by using the emulsification of the detergent and the friction action of the water flow due to the rotation of the washing blade, and the impact of the pulsator on the laundry. By detecting the amount and type of laundry, the washing method is automatically set, and the water level of the washing water is supplied to the appropriate level according to the amount and type of the laundry, and then washing is performed under the control of the microcomputer.

한편, 기존의 세탁기의 구동방식은 구동 모터의 회전동력을 동력전달용 벨트 및 풀리등을 개재하여 세탁축으로 전달하여 펄세이터를 회전시키거나 탈수축으로 전달하여 세탁조 겸용 탈수조를 회전시키는 방식과, BLDC 모터의 속도제어에 의해 세탁조 겸용 탈수조를 세탁 및 탈수시 각기 다른 속도로 회전시키는 방식이 있다.On the other hand, the driving method of the conventional washing machine is to transmit the rotational power of the drive motor to the washing shaft through the power transmission belt and pulley, etc. to rotate the pulsator or to the dehydration shaft to rotate the washing tank combined dehydration tank and By rotating the BLDC motor, there is a method of rotating the washing / dehydration tank for washing and dewatering at different speeds.

이와 더불어, BLDC 모터를 이용하면서도 동력전달 경로를 달리 제어하여 세탁시에는 펄세이터만을 저속회전시켜 세탁을 행하고, 탈수시에는 펄세이터 및 탈수조를 동시에 고속 회전시켜 탈수를 행하는 방식도 있다.In addition, there is also a method of controlling the power transmission path differently while using a BLDC motor to perform washing by rotating the pulsator at low speed during washing, and dehydrating by rotating the pulsator and the dehydrating tank at the same time at the same time.

또한, 세탁시 일정한 방향으로 세탁조 또는 세탁날개를 고속회전시키면서 펌핑된 수류를 세탁조 내로 분사하여 투과세탁을 수행하는 방식도 적용된다.In addition, a method of performing permeation by spraying the pumped water stream into the washing tank while rotating the washing tank or the washing blade at a high speed during washing is also applied.

도 1은 기존 세탁기의 일예를 나타낸 종단면도로서, BLDC 모터의 속도제어에 의해 세탁 및 탈수를 행하는 세탁기의 구조예를 나타낸 것이다.1 is a longitudinal sectional view showing an example of a conventional washing machine, and shows a structural example of a washing machine that performs washing and dehydration by speed control of a BLDC motor.

그 구성을 살펴보면, 아웃케이스(1) 내부로 서스펜션에 의해 지지되는 외조(1)가 설치되고, 상기 외조(2) 내에는 세탁조 겸용 탈수조(3)(이하, "세탁 조" 또는 "탈수조"중 어느 하나로 선택적으로 칭한다)가 회전 가능하게 설치된다.Looking at the configuration, the outer tank (1) supported by the suspension is installed in the outer case (1), the inside of the outer tank (2) combined washing tank dehydration tank (3) (hereinafter referred to as "washing tank" or "dehydration tank) "Optionally referred to as either" is rotatably installed.

그리고, 외조(2) 하면에 축받침판(5)이 조립되고, 상기 축받침판(5) 하면에 스테이터(6)가 조립되며, 축받침판(5)을 관통하는 축(4)의 하부에 스테이터(6)와 더불어 모터(M)를 이루는 로터(7)가 조립된다.In addition, the bearing plate 5 is assembled to the lower surface of the outer tub 2, the stator 6 is assembled to the lower surface of the bearing plate 5, and the stator is disposed below the shaft 4 passing through the bearing plate 5. 6) and the rotor 7 constituting the motor M is assembled.

또한, 상기 로터(7)의 중심부에는 축(4)의 외주면상에 결합됨과 더불어 상기 로터(7)에 체결되어 상기 로터(7)의 회전력을 축(4)으로 전달하는 커넥터(8)가 설치되고, 상기 로터(7)의 하단부에는 체결너트(10)가 로터(7)를 하부베어링(9) 쪽으로 밀착시키도록 체결된다.In addition, a connector 8 coupled to the outer circumferential surface of the shaft 4 and coupled to the rotor 7 to transfer the rotational force of the rotor 7 to the shaft 4 is installed at the center of the rotor 7. The fastening nut 10 is fastened to the lower end of the rotor 7 to bring the rotor 7 into close contact with the lower bearing 9.

이 때, 통상적으로 커넥터(8)는 플라스틱류로 만들어지게 된다.At this time, the connector 8 is usually made of plastics.

한편, 이와 같이 구성된 종래에는 모터 구동용 컨트롤러(도시는 생략함)의 제어에 의해 스테이터(6)의 코일에 순차적으로 전류가 흘러 로터(7)의 회전이 일어나면, 로터(7)에 결합된 컨넥터와 세레이션 결합된 축(4)이 회전하게 되어 세탁기가 운전된다.On the other hand, in the conventional configuration configured as described above, when a current flows sequentially in the coil of the stator 6 under the control of a motor driving controller (not shown), and the rotation of the rotor 7 occurs, the connector coupled to the rotor 7 The washing machine is operated by rotating the shaft 4 coupled with the serration.

그러나, 세탁기는 사용환경 및 운전조건에 따라 로터(7)의 온도변화가 크게 발생하게 되고, 이에 따라 상기 로터(7)의 중심부에 위치한 커넥터(8)가 팽창 및 수축하게 되는데, 상기 커넥터(8)가 팽창되었다가 수축될 경우 하부베어링(9)과 커넥터(8) 사이에 틈(GAP)이 발생하게 된다. However, in the washing machine, the temperature change of the rotor 7 is greatly generated according to the use environment and operating conditions, and thus the connector 8 located at the center of the rotor 7 is expanded and contracted. ) Is expanded and contracted, a gap is generated between the lower bearing 9 and the connector 8.

이 때, 상기 하부베어링(9)과 커넥터(8) 사이의 틈을 다르게 표현하면, 로터(7) 전체와 하부베어링(9) 사이의 틈을 의미하게 되며, 이는 축(4)방향을 따라 로터(7)의 유격(裕隔)이 있음을 의미한다. At this time, if the gap between the lower bearing 9 and the connector 8 is expressed differently, it means a gap between the entire rotor 7 and the lower bearing 9, which is the rotor along the axis 4 direction. (7) means there is play.                         

따라서, 종래에는 세탁기 운전시 로터(7)의 유격으로 인해 발생하는 소음이 발생하는 문제점이 있었다.Therefore, conventionally, there was a problem in that noise generated due to play of the rotor 7 during driving of the washing machine occurs.

A connector 8 coupled to the outer circumferential surface of the rotor 4 and coupled to the rotor 7 to transmit the rotational force of the rotor 7 to the shaft 4 is installed, and a lower end of the rotor 7 is coupled to the rotor 7. In the motor assembly structure of the fully automatic washing machine in which the nut (10) is fastened to bring the rotor (7) into close contact with the lower bearing (9); An elastic member 11 is provided between the lower bearing 9 and the connector 8 to be assembled on the shaft 4 to provide a clearance between the rotor 7 and the lower bearing 9. It is to prevent the occurrence.

이 때, 상기 탄성부재(11)로서는 스프링와셔 또는 중공형의 판스프링이 설치됨이 바람직하다.At this time, the elastic member 11 is preferably provided with a spring washer or a hollow leaf spring.

이와 같이 구성된 본 발명의 작용은 다음과 같다.The operation of the present invention configured as described above is as follows.

본 발명은 세탁기의 사용환경 및 운전조건에 따라 로터(7)의 온도변화가 크게 발생하여, 로터(7)의 중심부에 위치한 커넥터(8)가 수축하더라도 커넥터(8)와 하부베어링(9) 사이에 작용하는 일정 수준 이상의 면압에 의해 커넥터(8) 하부베어링(9) 사이에 틈이 발생하는 현상이 해소하게 된다.According to the present invention, a large change in temperature of the rotor 7 occurs according to the use environment and operating conditions of the washing machine, so that the connector 8 and the lower bearing 9 may be contracted even if the connector 8 located at the center of the rotor 7 shrinks. The gap between the lower bearings 9 of the connector 8 due to a surface pressure of a predetermined level or more acts on the nozzle is eliminated.

즉, 본 발명은 축(4)상의 하부베어링(9)과 커넥터(8) 사이에 일정한 크기 이상의 면압이 커넥터(8)와 하부베어링(9) 사이에 작용하도록 스프링와셔 등의 탄성부재(11)가 설치되어 있으므로 인해, 커넥터(8)와 하부베어링(9) 사이에 틈 발생이 방지되므로써 로터(7)의 유격이 해소된다.That is, in the present invention, an elastic member 11 such as a spring washer such that a surface pressure of a predetermined size or more is applied between the lower bearing 9 and the connector 8 on the shaft 4 between the connector 8 and the lower bearing 9. Since the gap between the connector 8 and the lower bearing 9 is prevented from occurring, the play of the rotor 7 is eliminated.

따라서, 본 발명에 따르면, 종래와는 달리 세탁기 운전시 로터(7)의 유격으로 인한 운전 소음이 발생하지 않게 된다.Therefore, according to the present invention, unlike the prior art, the operation noise due to the play of the rotor 7 is not generated when the washing machine is operated.

한편, 상기한 바와는 달리, 부품 상호간에 면압을 부여하는 탄성부재(11)는 로터(7)와 체결너트(10) 사이에 설치되어도 동일한 작용을 나타낼 수 있다.On the other hand, unlike the above, the elastic member 11 for imparting the surface pressure between the components may exhibit the same action even if installed between the rotor 7 and the fastening nut 10.

특히, 상기 탄성부재(11)가 커넥터(8)와 하부베어링(9) 사이 및, 체결너트(10)와 커넥터(8) 사이에 동시에 설치되는 경우에는 보다 확실하게 로터(7)의 유격을 방지할 수 있게 됨은 쉽게 알 수 있을 것이다.In particular, when the elastic member 11 is installed at the same time between the connector 8 and the lower bearing 9 and between the fastening nut 10 and the connector 8 at the same time, the play of the rotor 7 is more reliably prevented. Being able to do it is easy to see.
