This utility model discloses a water-cooled pressure cooking appliance, including a pot body and a pot lid. The pot lid is provided with a water-cooling cavity. The water-cooled pressure cooking appliance also includes a water tank detachably installed on the pot body or the pot lid. The bottom wall of the water tank is provided with a connecting port, which communicates with the water-cooling cavity. When the water tank is removed, coolant can be added to the water tank through the connecting port. The water tank is also provided with a baffle wall protruding towards the inside of the water tank, surrounding the outer periphery of the connecting port. When the water tank is inverted, as the user adds coolant to the water tank, the liquid level in the water tank gradually rises until it contacts the baffle wall. At this time, the coolant and the baffle wall form a water seal, and some air is trapped in the cavity area. The coolant does not completely fill the cavity area, thus strictly controlling the amount of coolant in the water tank. Furthermore, when the heated coolant flows back into the water tank, the risk of coolant overflowing from the vent is reduced because the coolant is far from the vent.
