A refrigerator provided with an inner panel molded through injection molding while an accommodation groove in which an installation member is accommodated is formed at the inner panel, and as a gasket is installed at an installation groove of the installation member, the use of a complex mold such as a slide core is minimized while making it easy to install the gasket at the inner panel. The interface includes a finite state machine for managing asynchronous and independent interactions between the internal circuits and external circuits. or more, by mixing an inert gas with water vapor, generating a hydroxide of metallic alkali by mixing the humidified gas with the exhaust gas; and trapping the generated hydroxide out of the mixture gas of the humidified gas and the exhaust gas. The controller in some examples also selectively controls the strength of the magnetic fields of the movers, which provides more customizable door performance.
