Abstract: A refrigeration appliance has a box body and a door arranged in the front of the box body, an accommodating cavity arranged at the top of the box body with a first inlet open upward to allow a control and/or power supply module to enter the accommodating cavity, and a top cap for closing the first inlet. The control and/or power supply module includes a first connector, and the accommodating cavity is arranged to open toward a rear side of the box body to allow a second connector to be engaged with the first connector from the rear side of the box body. This allows to increase a volume of the refrigeration appliance, and the control and/or power supply module is connected conveniently.
