This utility model relates to the field of household appliance technology, and discloses a steam generator and cooking appliance. The steam generator includes a water tank, a heating element, a water-blocking element, and an impeller assembly. The water tank has a cavity, and the heating element is disposed on the water tank. The water-blocking element includes a water-blocking plate, which is positioned below and close to the high water level line of the water tank, allowing fluid below the water-blocking plate to pass over it. The water is heated into steam and rises in gaseous form until it overflows the liquid surface. The function of the water-blocking plate is to puncture large air bubbles into smaller ones and increase water resistance, thereby preventing water droplets from splashing to the steam outlet, thus achieving stable separation of water and steam.

The invention discloses a spiral-wound membrane assembly, gas-liquid separation equipment and a gas-liquid separation method.The spiral-wound membrane assembly comprises a membrane unit and a central pipe, one side of the membrane unit is connected with the central pipe, and the membrane unit sequentially comprises a first membrane, a first flow guide net, a second membrane and a second flow guide net outwards from the face attached to the central pipe; gas flow channels are respectively formed between the first diaphragm and the second flow guide net and between the second diaphragm and the second flow guide net; a raw water flow channel is formed between the second diaphragm and the second flow guide net; a collecting hole is formed in the outer circumferential face of the center pipe and communicates with the gas flow channel, and a spiral groove is formed in the inner circumferential wall of the center pipe in the axis direction. To-be-treated liquid flows through the raw water flow channel from the water inlet port; under the driving of gas phase side pressure difference, gas in the liquid to be treated penetrates through the first diaphragm, the second diaphragm and the first flow guide net and enters the gas flow channel; and gas enters the central pipe through the collecting holes and is discharged. According to the spiral-wound membrane assembly, the permeation side flow resistance is reduced, and the permeation flux and the separation efficiency are improved.
