<p>The utility model relates to a refrigerator and an operation device. According to the operation device, the sensitivity of a touch switch can be adjusted without taking down the operation device from equipment bodies such as the refrigerator and without special operations of an operator. The refrigerator is provided with a storage chamber and the operation device. The operation device receives operations related to setting of the operative condition of the storage chamber and from the operator and is provided with the touch switch, a touch judging unit, a storage unit and a touch judging value correcting unit. The touch switch is used for detecting the static capacitance. The touch judging unit is used for judging whether operation input is conducted on the touch switch or not according to whether the variation of detection values detected by the touch switch exceeds a touch judging value or not. The storing unit is used for storing the variation of past detection values of the touch switch or storing information representing the tendency of the variation to serve as variation information. The touch judging value correcting unit is used for correcting a touch judging valve based on the variation information stored in the storing unit when the variation of the detection values of the touch switch exceeds the correcting judging value set as the value below the touch judging value.</p> |
