일반적으로 펄세이터형 세탁기는, 세탁조의 바닥에 설치된 펄세이터의 회전에 의해 수류가 발생되어 세탁행정이 이루어진다. 그리고 펄세이터와 함께 세탁조가 회전하여 세탁조 내부의 세탁물을 회전시킴으로써 원심력으로 세탁물에 함유된 수분을 탈취시키는 탈수행정이 이루어진다. 이러한 세탁행정이나 탈수행정은 모두 세탁조의 내부공간에서 이루어진다.In general, in the pulsator type washing machine, water flow is generated by the rotation of the pulsator provided at the bottom of the washing tank, and the washing operation is performed. In addition, the washing tank rotates together with the pulsator to rotate the laundry inside the washing tank so that a dehydration operation is performed to deodorize the moisture contained in the laundry by centrifugal force. Such washing administration or dehydration administration is all performed in the interior space of the washing tank.
그런데, 세탁조의 세탁공간은 하나의 챔버로 이루어져 있으므로, 세탁조에 담기는 모든 세탁물은 세탁도중 혼합된다. 따라서 염색섬유로 된 세탁물은 세탁도중 염색 원료가 물에 녹게 되는데, 이 염색 원료는 속옷 등 흰색의 세탁물에 특히 잘 배이게 된다.However, since the laundry space of the washing tank is composed of one chamber, all the laundry contained in the washing tank is mixed during the washing. Therefore, the laundry made of dyed fiber is dissolved in water during washing, the dyeing material is particularly well matched to white laundry such as underwear.
이와 같이 흰 세탁물이 변색되는 것을 방지하기 위해서는, 다양한 칼라를 갖는 거친 세탁물을 별도로 세탁하고, 희고 부드러운 세탁물들을 따로 세탁하여야 한다. 따라서 한번에 세탁할 수 있는 양의 빨랫감을 여러번에 나누어 세탁하여야 하는 경우가 발생하여 전력의 낭비 및 수돗물의 낭비가 큰 문제점이 있었다.In order to prevent the white laundry from discoloring in this way, the rough laundry having a variety of colors should be washed separately, and the white and soft laundry should be washed separately. Therefore, there is a case in which the amount of laundry that can be washed at a time is divided into several times to be washed, and waste of power and tap water have been a big problem.
본 발명은 상기한 종래의 문제점을 해결하기 위해 안출한 것으로, 본 발명의 목적은 세탁조 내에 소량의 세탁물을 담을 수 있는 다수의 챔버를 설치하여 세탁물별로 별도의 세탁실에서 세탁이 이루어지도록 함으로써, 분리를 요하는 세탁물의 훼손을 방지하고, 여러 종류의 세탁물을 동시 세탁할 수 있도록 하여 전력 및 수돗물의 낭비를 줄이기 위한 것이다.The present invention has been made to solve the above-mentioned conventional problems, an object of the present invention is to install a plurality of chambers that can hold a small amount of laundry in the washing tank to separate the laundry by washing in a separate laundry room, It is to prevent the washing of the required laundry and to be able to wash several kinds of laundry at the same time to reduce the waste of power and tap water.

To form a slope so as to be discharged to (232).
이하에서는 상기와 같은 구성을 갖는 세탁기의 작용을 설명한다.Hereinafter, the operation of the washing machine having the configuration as described above.
사용자는 세탁하고자 하는 세탁물중 일반 세탁물(300)을 세탁조(100) 내에 투입하고, 별도로 분리하여 세탁하고자 하는 소량의 세탁물(310, 320)을 보조 챔버(200)에 투입한다.The user inputs the general laundry 300 among the laundry to be washed into the washing tank 100, and inputs a small amount of laundry 310 and 320 to be separated and washed into the auxiliary chamber 200.
보조 챔버(200)에 세탁물(310, 320)을 투입하기 위하여, 보조 챔버(200)의 상부를 닫고 있는 도어(210)의 손잡이에 손가락을 걸고 도어(210)를 오픈시킨다. 도어(210)는 힌지축(232)을 중심으로 회동하여 보조 챔버(200)의 상부를 개방시킨다. 사용자는 개방된 보조 챔버(200)에 소량의 세탁물(310, 320)을 투입하고, 도어(210)에서 손을 뗀다. 이에 따라 도어(210)를 닫히는 방향으로 탄지하는 비틀림 스프링(234)의 탄성에 의해 도어(210)는 보조 챔버(200)의 상방을 폐쇄한다.In order to inject laundry 310 and 320 into the auxiliary chamber 200, the door 210 is opened by putting a finger on the handle of the door 210 closing the upper part of the auxiliary chamber 200. The door 210 rotates about the hinge shaft 232 to open the upper portion of the auxiliary chamber 200. The user puts a small amount of laundry (310, 320) into the open auxiliary chamber 200, and removes the hand from the door (210). As a result, the door 210 closes the upper side of the auxiliary chamber 200 by the elasticity of the torsion spring 234 that touches the door 210 in the closing direction.
세탁물 투입과정을 마치면, 사용자는 세탁기를 조작하여 세탁시작을 선택한다.After the laundry loading process, the user operates the washing machine and selects the start of washing.
이에 따라 세탁기는 세탁행정에 대비하기 위하여 먼저 저수조(130) 내에 세탁수를 충전한다.Accordingly, the washing machine first fills the washing water in the reservoir 130 to prepare for the washing operation.
이때에는 모터(140)를 회전시켜 벨트(150) 및 풀리(160)와감속기어박스(170) 및 회전축(180)을 통하여 세탁조(100)를 서서히 회전시키면서, 세탁수 공급관(120)을 개방하여 메인 급수로(122)로 세탁수를 공급한다.At this time, while rotating the washing tank 100 through the belt 150, the pulley 160, the reduction gear box 170 and the rotating shaft 180 by rotating the motor 140, by opening the washing water supply pipe 120 The wash water is supplied to the main water supply passage 122.
메인 급수로(122)로 낙하되는 세탁수중 일부는 급수구(220)로 유입되어 세탁수 공급관(120)을 통하여 보조 챔버(200)내로 공급된다. 세탁조(100)가 회전하므로, 다수의 급수구(220)가 차례로 세탁수 공급관(120)의 하방에 위치하여 세탁수를 공급받게 된다.Some of the washing water falling into the main water supply passage 122 flows into the water supply port 220 and is supplied into the auxiliary chamber 200 through the washing water supply pipe 120. Since the washing tub 100 rotates, a plurality of water inlets 220 are sequentially positioned below the washing water supply pipe 120 to receive the washing water.
이와 같이 하여 세탁조(100) 및 각 보조 챔버(200)내에 세탁수가 완충되면, 세탁행정으로 진행하게 된다.In this way, when the washing water is buffered in the washing tank 100 and each auxiliary chamber 200, the process proceeds to the washing operation.
보조 챔버(200)내의 소량의 세탁물(310, 320)은 세탁조(100) 내의 세탁물(300)과 격리되어 있으므로, 세탁조(100) 내에서 발생하는 염료의 분해된 성분이나 기타 더러운 때물이 보조 챔버(200) 내로 유입되지 않으므로 보조 챔버(200)내의 세탁물(310, 320)은 깨끗한 상태로 세탁된다.Since a small amount of laundry (310, 320) in the auxiliary chamber 200 is isolated from the laundry 300 in the washing tank 100, decomposed components of the dye generated in the washing tank 100, or other dirty when the dirt is stored in the auxiliary chamber ( Since it does not flow into the 200, the laundry (310, 320) in the auxiliary chamber 200 is washed in a clean state.
한편, 세탁행정이 종료되고 탈수행정이 시작되면, 세탁조(100)가 고속으로 회전하여 세탁조(100)내의 세탁물(300)에 함유된 수분을 원심력으로 탈수시킨다. 이때 세탁조(100)와 함께 급수관(230)도 함께 회전하므로, 보조 챔버(200)내의 세탁수가 경사진 급수관(230)을 역류하여 배수구(232)로 배출된다.On the other hand, when the washing cycle is finished and the dehydration stroke is started, the washing tank 100 is rotated at high speed to dehydrate the water contained in the laundry 300 in the washing tank 100 by centrifugal force. At this time, since the water supply pipe 230 also rotates together with the washing tank 100, the washing water in the auxiliary chamber 200 flows backward to the inclined water supply pipe 230 and is discharged to the drain 232.
이상에서 설명한 바와 같이 본 발명은, 세탁수 공급관(120)으로부터 일부의 세탁수를 공급받는 1이상의 급수구(220)와, 각 급수구(220)로부터 세탁조(100)의 바닥으로 연장되는 급수관(230)과, 각 급수관(230)의 하단에 연결되어 세탁조(100)의 바닥 가장자리에 안착되는 보조 챔버(200)와, 각 보조 챔버(200)의 상방을 개폐하는 도어(210)를 갖는 다중 세탁실을 갖는 세탁기로서, 다수의 보조 챔버(200) 내에 분리를 요하는 소량의 세탁물(310, 320)을 투입하고 세탁조(100) 내의 다량의 세탁물(300)과 동시에 세탁을 할 수 있으므로, 분리를 요하는 세탁물(310, 320)의 훼손을 방지하고, 여러 종류의 세탁물을 동시에 세탁함으로써 세탁수 및 전력을 절약할 수 있는 효과가 있다.As described above, the present invention provides at least one water supply port 220 that receives a part of the washing water from the washing water supply pipe 120, and a water supply pipe extending from each water supply port 220 to the bottom of the washing tank 100 ( 230, a plurality of laundry rooms having an auxiliary chamber 200 connected to the lower end of each water supply pipe 230 and seated at the bottom edge of the washing tub 100, and a door 210 opening and closing the upper side of each auxiliary chamber 200.
