Abstract

A refrigerator includes a door that has a front panel with an operation area to receive a touch operation of a user; a touch sensor assembly that is located rearward the operation area and that includes sensors to generate an input signal based on the touch operation; and a sensor controller connected to the touch sensor assembly and configured to process the input signal received from the touch sensor assembly. The sensor controller is configured to determine whether the touch operation is a push operation or a release operation based on comparison of a voltage value of the processed input signal to predetermined first and second threshold voltage values.

Description

technical field [0001] The present disclosure relates to a refrigerator including a touch sensor. Background technique [0002] A refrigerator is a device capable of keeping objects such as food and drink fresh by cooling its freezer or refrigerating chamber to a certain temperature through repeated freezing or refrigerating cycles. For example, a refrigerator includes a main body that defines a storage space and a door that opens and closes the storage space. The storage space can store items such as food, and the user can open the door to store the items or take out the stored items. [0003] Recently, demand for additional functions of refrigerators other than the basic functions described above is increasing. For example, the door of a refrigerator may include an interface capable of displaying various pieces of information related to the refrigerator (such as information about controlling the refrigerator and information about items stored in the refrigerator) to allo...
