Abstract: The present application relates to the field of refrigeration, and provides door assembly and refrigeration equipment. The door assembly includes: a door leaf, including a first door body and a second door body, where the first door body is configured to be rotatably connected to an installation part, and the second door body is configured to move toward an opening side or a hinged side of the first door body with respect to the first door body to switch between a sealing position and an avoidance position; the door leaf is configured to switch between a closing state in which the second door body is in the sealing position and an opening state; the second door body is in the avoidance position when the door leaf is switched between the closing state and the opening state. When the door leaf is in a closing state, the second door body is in the sealing position to ensure the sealing effect of the door leaf.

Abstract: The present application relates to the field of storage technology, and provides a door assembly and a storage cabinet. The door assembly includes a door body provided with a handle groove; a driving assembly; a rack hinged to the door body and provided with a cover plate assembly; and a first detecting member configured to generate a first detecting signal; where the driving assembly is adapted to drive the rack to switch between a pressing state and a resetting state based on the first detecting signal; and in the pressing state, the cover plate assembly avoids the handle groove, and in the resetting state, the cover plate assembly shields the handle groove.

Abstract: An oxygen removal module, a fresh-keeping device and a refrigerator. The oxygen removal module comprises: an electrolyte tank provided with a water inlet; and a water tank provided with a water outlet, the water outlet being connected to the water inlet through a first pipeline, to supplement water to the electrolyte tank by means of the water tank.

Abstract: A refrigerator may include an air duct cover plate, a closed air cavity, an evaporator, and an air guiding rib. The air duct cover plate and a liner of the refrigerator enclose the closed air cavity. The evaporator is disposed on an outer surface of the liner. The air guiding rib is disposed in the closed air cavity. The air guiding rib divides the closed air cavity into an air intake region, a first supply region, and a second supply region that are sequentially in fluid communication. The first supply region is located above the air intake region and includes an upper air outlet. The second supply region is located below the first supply region and is separated from the air intake region by the air guiding rib. A lower air outlet is disposed in the second supply region.
