    摘要: A washing machine appliance and methods of operating a washing machine appliance are provided. The washing machine appliance includes a tub and a rotatable basket within the tub. A volume of water is flows into the tub, causing a load of articles in the basket to be wetted. A first weight of the load of articles is measured during an initial spin operation after flowing the volume of water into the wash tub. A water extraction operation is performed after measuring the first weight of the load of articles. A second weight of the load of articles is measured after the water extraction operation. A load type of the load of articles is determined based on the first weight and the second weight.

    摘要: A washing machine appliance and methods of operating a washing machine appliance are provided. The washing machine appliance includes a motor and a rotatable basket. The motor is operated to rotate the basket to a first speed. The basket is then decelerated from the first speed to a second speed less than the first speed. A deceleration time is determined while decelerating the basket from the first speed to the second speed. The method may include, or the washing machine appliance may be configured for, determining a size of a load of articles in the basket of the washing machine appliance based on the deceleration time. Based on the determined size of the load, one or more operating parameters of the washing machine appliance are selected and an operation of the washing machine appliance is performed according to the one or more selected operating parameters.

    摘要: A washing machine appliance and methods of operating a washing machine appliance are provided. The washing machine appliance includes a motor and a rotatable basket. The motor is operated to rotate the basket. While operating the motor to rotate the basket, a power consumption and a balance condition of a load of articles in the basket are determined. A size of the load of articles in the basket of the washing machine appliance is determined based on the power consumption and the balance condition. Based on the determined size of the load, one or more operating parameters of the washing machine appliance are selected and an operation of the washing machine appliance is performed according to the one or more selected operating parameters.

    摘要: A dishwasher includes a tub defining a wash chamber, a wash rack provided within the wash chamber, an air inlet in fluid communication with the wash chamber at a first position, an air exhaust outlet in fluid communication with the wash chamber at a second position different from the first position, a first gas sensor provided in the dishwasher, and a controller configured to initiate an operation sequence. The operation sequence includes initiating a drying cycle, receiving an air-quality signal from the first gas sensor, measuring, during the drying cycle, an air-quality characteristic within the wash chamber of the dishwasher, determining the measured air-quality characteristic is below a predetermined air-quality threshold, calculating a drying time in response to determining the measured air-quality characteristic is below the predetermined air-quality threshold, and halting the drying cycle in response to an expiration of the drying time.
