본 발명은 세탁기와 건조기에 관한 것으로, 특히 세탁기와 건조기 간 데이터 통신을 구현하는 세탁기와 건조기 간 통신 제어방법에 관한 것이다.The present invention relates to a washing machine and a dryer, and more particularly, to a communication control method between a washing machine and a dryer for implementing data communication between the washing machine and a dryer.

일반적으로, 세탁기는 가정에 비치되어 가장 보편적으로 이용되는 가전제품 중의 하나로서, 세제의 유화작용, 회전운동에 따른 세탁 수류의 마찰작용과 세탁물 과의 충격작용 등을 이용하여 세탁 대상물에 부착되어 있는 오염물을 깨끗하게 세탁하는 기기이다.In general, a washing machine is one of the most commonly used household appliances provided at home, and is attached to an object to be washed by using emulsification of detergent, friction of washing water due to rotational movement, and impact on laundry. The machine cleans contaminants.

보통, 가정에서 이용되는 세탁기는 와류형, 교반식, 드럼식 등 다양한 세탁방식을 적용한 제품이 출시되고 있으며, 세탁조와 탈수조의 분리 여부에 따라 분리식과 전자동식으로 구분할 수도 있다.In general, the washing machine used at home is a product that applies a variety of washing methods such as vortex type, stirring type, drum type is released, and may be divided into a separate type and a fully automatic type depending on whether the washing tank and the dehydration tank are separated.

통상, 세탁행정은 세제와 세탁수, 세탁 대상물을 넣고 일정시간 동안 세탁날개를 교반시키면서 세탁수에 함유된 세제의 화학작용과 세탁날개의 물리적 작용으로 세탁물에 묻어있는 오염물질이 제거되도록 하는 과정이다.In general, the washing administration is a process of removing contaminants on laundry by putting detergent, washing water and objects to be washed and stirring washing blades for a predetermined time by chemical action of detergent contained in washing water and physical action of washing blades. .

그리고, 헹굼 행정은 세제가 혼합되지 않은 세탁수를 공급하여 상기 세탁물에 묻어있는 세제성분과 오염물질을 깨끗하게 헹궈내는 과정이고, 탈수 행정은 상기 헹굼 행정의 종료 후에 세탁조를 고속으로 회전시키면서 세탁 대상물에 포함된 수분을 탈수시키는 과정이다.In addition, the rinsing stroke is a process of supplying the washing water not mixed with the detergent to rinse the detergent components and contaminants in the laundry cleanly, and the dehydration stroke is performed on the laundry object while rotating the washing tank at a high speed after the rinsing stroke is finished. It is the process of dehydrating the moisture contained.

한편, 가정에서 많이 이용되는 가전제품 중 하나인 의류 건조기는 세탁기와 별개로 설치하여 젖은 상태의 의류를 자동으로 건조하도록 한 기기로, 건조방식에 따라 제습식과 배기식으로 구분한다.On the other hand, the clothes dryer, one of the home appliances that are used at home, is installed separately from the washing machine to automatically dry the wet clothes, and is classified into a dehumidification type and an exhaust type according to the drying method.

먼저, 제습식 의류 건조기는 내부에 열교환기를 구비하여 공기가 건조기 안에서 순환되어 습기를 응축시킴으로써 물은 건조기 외부로 배출하고, 공기는 다시 히터로 가열하여 드럼 내부로 공급하면서 의류를 건조하는 방식이다.First, the dehumidifying clothes dryer has a heat exchanger therein, and air is circulated in the dryer to condense moisture to discharge water to the outside of the dryer, and the air is heated by a heater to supply the inside of the drum to dry clothes.

그리고, 배기식 의류 건조기는 건조기 외부의 공기를 흡입하여 히터로 가열한 다음에 드럼으로 유도하였다가 다시 건조기 외부로 배출하는 과정에서 드럼 안 의 의류를 건조하는 방식이다.In addition, the exhaust clothes dryer is a method of drying the clothes in the drum in the process of sucking the air from the outside of the dryer, heated by a heater, guided to the drum and then discharged to the outside of the dryer.

이러한 세탁기 및 건조기는 각각 별도로 설치하여 개별적으로 이용하게 되는데, 통상 세탁기에서 세탁 완료된 의류를 꺼내 건조기로 이동하여 젖은 상태의 의류를 건조기의 열풍을 이용하여 건조를 수행하게 된다.These washing machines and dryers are separately installed and used separately. Usually, the clothes which have been washed are removed from the washing machine and moved to the dryer to dry the wet clothes using the hot air of the dryer.

그러나, 이러한 과정에서 건조기는 세탁기에서 적용된 포량 등의 세탁정보를 이용하지 못하여 해당 세탁정보를 사용자가 건조기에 직접 재입력해야 하는 번거로운 문제점이 있었다.However, in this process, the dryer cannot use the washing information such as the quantity applied in the washing machine, and there is a problem in that the user has to directly retype the washing information into the dryer.

이를 해결하기 위해, 최근에는 세탁기의 세탁정보를 건조기에서 수신하여 동일한 세탁정보로 세탁에 이어 건조행정을 수행할 수 있도록 세탁기와 건조기간 데이터 통신을 제공하는 기술이 연구되고 있다.In order to solve this problem, recently, a technology for providing data communication with a washing machine and a drying period has been studied to receive washing information of a washing machine in a dryer and perform a drying administration following washing with the same washing information.

예컨대, 국내특허 출원번호 제2002-0073609호에 개시된 바와 같이 통신 가능한 건조기와 세탁기가 개발되고 있다.For example, as disclosed in Korean Patent Application No. 2002-0073609, a communication dryer and a washing machine have been developed.

도 1에 도시한 바와 같이, 양간의 데이터 통신을 위해 RS-232C 통신 케이블의 시리얼(Serial) 통신라인을 통해 세탁기(10)와 건조기(20)를 연결 구성한다. 여기서, 상기 세탁기(10)와 건조기(20)는 RS-232C 통신 프로토콜에 의해 데이터를 송수신하도록 해당 통신 모듈이 각각 내장되어 있다.As shown in FIG. 1, the washing machine 10 and the dryer 20 are connected to each other through a serial communication line of an RS-232C communication cable for data communication between the two. Here, the washing machine 10 and the dryer 20 each have a corresponding communication module so as to transmit and receive data by the RS-232C communication protocol.

그 제어 동작을 설명하면, 세탁기(10)가 현재 진행하고 있는 세탁행정이 완료되면 건조기(20)와의 통신을 시도한다. 이때, 사용자가 건조기(20)의 행정 개시명령을 입력하면 세탁기(10)와의 통신이 이루어지는데 세탁기(10)에서 최근 수행된 행정의 세탁정보를 건조기(20)로 송신하게 된다.The control operation will be described. When the washing operation 10 is completed, the washing machine 10 attempts communication with the dryer 20. At this time, when a user inputs an administration start command of the dryer 20, communication with the washing machine 10 is performed, and washing information of a stroke recently performed in the washing machine 10 is transmitted to the dryer 20.

여기서, 상기 세탁기(10)에서 건조기(20)로 송신하는 세탁정보는 최근 수행한 세탁 알고리즘 정보, 포량, 포질 등으로 이루어진 세탁관련 정보이다.Here, the washing information transmitted from the washing machine 10 to the dryer 20 is washing related information consisting of recently performed washing algorithm information, quantity, and quality.

이후, 상기 건조기(20)는 세탁기(10)로부터 수신된 세탁정보를 토대로 건조시간 등을 결정하여 건조를 수행한다.Thereafter, the dryer 20 determines drying time and the like based on the washing information received from the washing machine 10 to perform drying.

따라서, RS-232C 통신 케이블을 통해 세탁기(10)와 건조기(20)를 연결 구성함에 따라 건조기(20)가 세탁기(10)의 세탁정보를 그대로 이용하여 건조행정을 수행할 수 있다.Therefore, as the washing machine 10 and the dryer 20 are connected to each other through the RS-232C communication cable, the dryer 20 may perform a drying operation using the washing information of the washing machine 10 as it is.

상술한 바와 같이 종래 기술에 따른 세탁기와 건조기는 유선 케이블로 연결되는데, 시리얼 통신(RS-232 통신)을 위한 포트용 케이블은 길이의 제한이 있었다. 즉, 세탁기와 건조기간의 거리가 멀어질수록 유선 연결이 어려워지는 문제점이 있었다.As described above, the washing machine and the dryer according to the prior art are connected by a wired cable, and the cable for the port for serial communication (RS-232 communication) has a length limitation. In other words, as the distance between the washing machine and the dryer increases, the wired connection becomes difficult.

또한, 유선 케이블이 세탁기나 건조기에 오랜 시간 걸려있거나 외부로 노출되어 경우 포트가 소손될 우려가 있었다.In addition, if a wired cable is hung in a washing machine or a dryer for a long time or exposed to the outside, the port may be damaged.

따라서, 본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위해 안출한 것으로, 본 발명의 목적은 데이터 통신이 가능한 세탁기와 건조기에 있어 거리상의 제약을 없애기 위한 세탁기와 건조기 간 통신 제어방법을 제공하는데 있다.Accordingly, the present invention has been made to solve the above problems of the prior art, an object of the present invention is to provide a communication control method between the washing machine and the dryer to remove the constraint on the distance in the washing machine and dryer capable of data communication have.

본 발명의 다른 목적은 미관상 보다 정리된 외관을 제공하기 위한 세탁기와 건조기 간 통신 제어방법을 제공하는데 있다.Another object of the present invention is to provide a communication control method between a washing machine and a dryer to provide a more clean appearance.

이와 같은 목적을 달성하기 위한 본 발명에 따른 세탁기와 건조기 간 통신 제어방법은 사용자가 입력한 세탁정보에 따라 세탁대상물에 대한 세탁행정을 수행한 후 최근 수행된 세탁행정의 세탁정보를 외부로 송신하는 세탁기와, 세탁기와의 통신을 통해 세탁기로부터 수신된 세탁정보에 따라 건조를 수행하는 건조기로 구성된 세탁기와 건조기 간 통신 제어방법에 있어서, 상기 세탁기와 건조기는; 세탁기와 건조기 간 통신 데이터를 RF(radio frequency) 통신방식으로 송/수신하도록 RF 통신모듈이 각각 내장되며, 건조기 마이컴은 세탁기로부터 수신된 세탁정보를 근거하여 건조시간 등 행정 조건을 결정한 후 결정된 행정조건에 따라 건조를 수행하는 단계를 포함하는데 특징이 있다.In order to achieve the above object, a communication control method between a washing machine and a dryer according to the present invention transmits washing information of a recently performed washing administration after performing a washing administration on a laundry object according to washing information input by a user. A washing machine and a dryer comprising a dryer for performing drying in accordance with washing information received from a washing machine through communication with the washing machine, the communication control method comprising: a washing machine and a dryer; Each RF communication module is embedded to transmit / receive the communication data between the washing machine and the dryer by a radio frequency (RF) communication method, and the dryer microcomputer determines the administrative conditions such as drying time based on the washing information received from the washing machine. It is characterized in that it comprises the step of performing the drying.

따라서, 본 발명에 의하면 세탁기와 건조기간 통신 케이블을 RF 통신모듈로 변경함으로써 케이블 길이에 따른 거리의 제한을 해결하고 유선 케이블 이용으로 인한 안전사고나 케이블 소손 등을 방지할 수 있다.Therefore, according to the present invention, by changing the washing machine and the drying period communication cable to the RF communication module, it is possible to solve the limitation of the distance according to the cable length and to prevent the safety accident or the cable burnout due to the use of the wired cable.

이하 상기의 목적을 구체적으로 실현할 수 있는 본 발명의 바람직한 실시예를 첨부한 도면을 참조하여 설명한다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention that can specifically realize the above object will be described.
