It can be understood that the first switch 342 , the second switch 344 , the third switch 346 and the fourth switch 348 may be switches capable of controlling fluid flow, such as solenoid valves and water pumps.

In the steam cooking device 100 of the embodiment shown in FIG. 10 , the switch assembly 34 includes a first switch 342 , a second switch 344 , a third switch 346 and a fourth switch 348 , and the external water tank 32 is connected to the water inlet through the first switch 342 222, and connect the water outlet 224 through the second switch 344.

The steam generator 40 includes a first port, a second port and a third port, the water outlet 224 is connected to the first port through a third switch 346, the second port of the steam generator 40 is connected to the cavity 10, and the third port of the steam generator 40 is connected to the first port. The port is connected to the external water tank 32 through the fourth switch 348.

After the steam cooking device 100 is started, the controller 36 controls the first switch 342 to fill the water in the external water tank 32 into the condensed water tank 22 . The controller 36 controls the third switch 346 to fill the water in the condensed water tank 22 into the steam generator 40 , and the steam generator 40 is heated to generate water vapor to enter the cavity 10 .

The water vapor in the cavity 10 overflows and enters the water cooling device 20 from the exhaust port 12, and the water cooling device 20 absorbs heat to condense the water vapor. The water in the condensed water tank 22 is continuously consumed, and is replenished from the external water tank 32 to the built-in water tank, and plays a cooling role. The water in the condensed water tank 22 keeps a certain amount all the time. When the controller 36 judges that the temperature in the condensed water tank 22 is too high according to the temperature detected by the temperature sensor 21, it controls the first switch 342 and the second switch 344, and the hot water in the condensed water tank 22 is discharged to the external water tank 32. The cold water in the water tank 32 is filled into the condensed water tank 22, and the temperature in the condensed water tank 22 is lowered by continuous circulation so as to achieve the purpose of condensing the steam.

After the steam cooking device 100 works for a period of time, the temperature of the water in the condensed water tank 22 rises to a constant temperature, and the water supply temperature of the steam generator 40 is higher, so that the speed of steam generation is accelerated, the heating efficiency is improved, and energy is saved.

After the steam cooking device 100 finishes working, the controller 36 controls the second switch 344 and the fourth switch 348 to discharge the water in the condensed water tank 22 and the remaining water in the steam generator 40 to the external water tank 32 .

In this embodiment, a fan 25 is arranged outside the condensed water tank 22, and the fan 25 is an independent unit, which plays an auxiliary cooling role. In some embodiments, the steam cooking device 100 can also eliminate the fan 25 .

It can be understood that the first switch 342 , the second switch 344 , the third switch 346 and the fourth switch 348 may be switches capable of controlling fluid flow, such as solenoid valves and water pumps.

It should be noted that the amount of water in the condensed water tank 22 can be detected by the water level sensor 23 , or can be calculated by the open time of the first switch 342 and the flow rate per unit open time.

In addition, in the steam cooking device 100 of the embodiment shown in Figs. 5-10, the water cooling device 20 may be the water cooling device 20 of any of the above embodiments.
