Abstract
The utility model provides refrigeration equipment and a vacuum device, the vacuum device comprises a vacuum box and a vacuumizing unit, and the vacuum box comprises a box body and a box cover. The first side edge of the box cover is rotatably connected to the box body so that the containing cavity of the box body can be opened and closed. And when the box body is closed by the box cover, the sealing ring is elastically pressed on the box cover so as to seal the accommodating cavity. A limiting clamping hook is arranged on the second side edge of the box cover and extends towards the box body; the box body is provided with the limiting clamping protrusion, and the limiting clamping hook is detachably clamped on the limiting clamping protrusion so that closing of the box cover and the box cover can be kept, press fit of the sealing ring on the box cover can be kept, tight press fit of the sealing ring can be effectively guaranteed, and sealing of the sealing ring can be effectively kept.
