Abstract

본 발명은 세탁기에서 세탁기의 포량을 감지하는 기술에 관한 것으로, 종래의 포량감지 수단에 있어서는 중량 변화에 대한 변위 대 주파수를 룩업테이블로 구축하였기 때문에 센서 및 사용조건의 변화에 따라 오차가 발생하는 결함이 있었는 바, 본 발명은 이를 해결하기 위하여, 제품 출하전 세탁조의 무게를 일정 단위로 증가시키면서 중량센서의 출력주파수를 읽어 그 출력주파수와 단위 무게당 주파수 증가율을 기억장치에 저장한 후, 세탁기에 전원이 투입될 때 상기 중량센서의 출력주파수를 측정하고, 이를 근거로 초기치를 설정하며, 이후, 세탁포의 투입에 의해 증가되는 상기 중량센서의 출력주파수를 검출하여 초기치를 기준으로 주파수 증가율을 구하고, 이를 근거로 상기 기억장치에 저장된 데이탈을 참조하여 포량을 계산하도록 하였다.The present invention relates to a technique for detecting a quantity of a washing machine in a washing machine. In the conventional quantity detecting means, since a displacement versus frequency for a weight change is constructed as a lookup table, an error occurs according to a change in a sensor and a use condition. In order to solve this problem, the present invention reads the output frequency of the weight sensor while increasing the weight of the washing tank in a predetermined unit before shipment of the product, and stores the output frequency and the frequency increase rate per unit weight in the storage device. When the power is turned on, the output frequency of the weight sensor is measured, and the initial value is set based on this. Then, the frequency increase rate is obtained based on the initial value by detecting the output frequency of the weight sensor increased by the input of the laundry cloth. On the basis of this, the dose is calculated by referring to the data stored in the storage device.

세탁물과 물의 무게로 인한 세탁조의 변위를 중량센서로 측정하여 세탁조에 걸리는 하중을 직접 감지하는 방식으로 투입된 세탁물의 포량과 급수량을 감지하고, 이 감지된 정보를 이용하여 세탁행정을 수행하는 세탁기의 포량방법에 있어서, 제품 출하전 세탁조의 무게를 일정 단위로 증가시키면서 중량센서의 출력주파수를 읽어 그 출력주파수와 단위 무게당 주파수 증가율을 기억장치에 저장하는 단계와, 세탁기에 전원이 투입될 때 상기 중량센서의 출력주파수를 측정하고, 이를 근거로 초기치를 설정하는 단계와, 세탁포의 투입에 의해 증가되는 상기 중량센서의 출력주파수를 검출하여 초기치를 기준으로 주파수 증가율을 구하고, 이를 근거로 상기 기억장치에 저장된 데이타를 참조하여 포량을 계산하는 단계로 이루어지는 것을 특징으로 하는 중량센서를 채용한 세탁기의 포량감지 방법.The displacement of the washing tank due to the weight of the laundry and water is measured by the weight sensor to detect the amount of water and the amount of water supplied to the washing tank directly, and the amount of washing machine performs the washing administration using the detected information. The method includes reading the output frequency of the weight sensor while increasing the weight of the washing tub before shipment of the product in a predetermined unit and storing the output frequency and the frequency increase rate per unit weight in a storage device, and when the power is supplied to the washing machine. Measuring an output frequency of the sensor, setting an initial value based on the sensor, and detecting an output frequency of the weight sensor increased by the introduction of a laundry cloth to obtain a frequency increase rate based on the initial value; Calculating a dose by referring to the data stored in the Poryang detection method of a washing machine employing a quantity sensor. 제1항에 있어서, 제품 출하전 세탁조의 무게를 일정치로 설정하여 저장한 후, 전원투입시 중량센서의 출력주파수를 측정하여 그 측정된 주파수가 저장된 주파수에 비하여 이상으로 판명되면 그 값을 투입된 무게로 계산하고, 이후 포의 투입에 따라 증가되는 무게와 더하는 단계를 포함하여 이루어지는 것을 특징으로 하는 중량센서를 채용한 세탁기의 포량감지 방법.According to claim 1, after setting the weight of the washing tank before shipping the product to a certain value and stored, and measuring the output frequency of the weight sensor when the power supply is turned on if the measured frequency is found to be higher than the stored frequency Calculation of the weight, and the amount of weight detection method of the washing machine employing a weight sensor, characterized in that it comprises the step of adding and increasing the weight of the cloth. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
