A humidity sensor (not shown) and a pump 35 are connected.

  The control device 80 includes a microcomputer, an input / output circuit, and the like, and based on detection signals from the water tank water level sensor 36, the water level sensor 43, the temperature sensor, and the humidity sensor, the blower fan 28, the first steam heater 52, and the like. The second steam heater 53, the damper 68, the drain valve 70, the steam generating heater 42, the operation panel 11 and the pump 35 are controlled according to a predetermined program.

  In the steam cooker 1 configured as described above, a power switch (not shown) in the operation panel 11 is pressed to turn on the power, and the operation of the operation panel 11 starts the cooking operation. Then, the control device 80 first starts the operation of the pump 35 with the drain valve 70 closed and the exhaust passage 67 closed by the damper 68. Water is supplied into the pot 41 of the steam generator 40 from the water tank 30 through the first to fourth water supply pipes 31 to 34 by the pump 35. And if the water level sensor 43 detects that the water level in the said pot 41 reached the predetermined water level, the pump 35 will be stopped and water supply will be stopped.

  Next, the steam generating heater 42 is energized, and a predetermined amount of water accumulated in the pot 41 is heated by the steam generating heater 42.

  Next, simultaneously with the energization of the steam generating heater 42 or when the temperature of the water in the pot 41 reaches a predetermined temperature, the blower fan 28 is turned on and the first steam heating heater 52 of the steam heating device 50 is energized. To do. Then, the blower fan 28 sucks air (including steam) in the heating chamber 20 from the suction port 25 and sends out air (including steam) to the circulation path 60. Since a centrifugal fan is used as the blower fan 28, a higher pressure can be generated compared to the propeller fan. Furthermore, by rotating the centrifugal fan used for the blower fan 28 at a high speed with a DC motor, the flow velocity of the circulating airflow can be extremely increased.

  Next, when the water in the pot 41 of the steam generator 40 boils, saturated steam is generated, and the generated saturated steam joins the circulating airflow passing through the circulation path 60 at the steam suction ejector 44. The steam discharged from the steam suction ejector 44 flows into the steam temperature raising device 50 through the second pipe 63 at a high speed.

  And the steam which flowed into the said steam temperature rising apparatus 50 is heated by the 1st steam heating heater 52, and turns into a superheated steam of about 300 degreeC (it changes with cooking contents). A part of the superheated steam is ejected downward from the plurality of ceiling steam outlets 55 provided in the lower ceiling panel 54 in the heating chamber 20. Further, another part of the superheated steam is ejected from the side surface steam outlets 22 on both side surfaces of the heating chamber 20 through the steam supply passages 23 provided on both the left and right sides of the steam heating device 50.

  Thereby, the superheated steam ejected from the ceiling side of the heating chamber 20 is vigorously supplied toward the heated object 90 in the center, and the superheated steam ejected from the left and right side surfaces of the heating chamber 20 Then, the product is supplied while being lifted so as to wrap the heated object 90 from below the heated object 90. As a result, convection occurs in the heating chamber 20 in such a manner that it is blown down at the center and rises outside the center. Then, the convection steam is sequentially sucked into the suction port 25 and repeats circulation such that it returns to the heating chamber 20 through the circulation path 60 again.

  By forming convection of superheated steam in the heating chamber 20 in this way, the superheated steam from the steam heating device 50 is sent to the ceiling steam outlet while maintaining the temperature and humidity distribution in the heating chamber 20 uniform. 55 and the side air outlet 22, and can efficiently collide with the heated object 90 placed on the rack 24. Then, the object to be heated 90 is heated by the collision of superheated steam. At this time, the superheated steam in contact with the surface of the object to be heated 90 also heats the object to be heated 90 by releasing latent heat when dew condensation occurs on the surface of the object to be heated 90. As a result, a large amount of heat of the superheated steam can be uniformly and quickly applied to the entire surface of the article 90 to be heated. Therefore, it is possible to realize cooking with no unevenness and good finish.

  Further, in the above cooking operation, when time elapses, the amount of steam in the heating chamber 20 increases, and the surplus amount of steam passes from the discharge port 27 through the discharge passage 64 and the exhaust duct 65. And discharged from the exhaust port 66 to the outside. At this time, the steam 69 passing through the discharge passage 64 is cooled and condensed by the radiator 69 provided in the discharge passage 64, thereby preventing the steam from being discharged to the outside as it is. The water condensed in the discharge passage 64 by the radiator 69 flows down in the discharge passage 64 and is guided to the receiving tray 21, and is processed together with the water generated by cooking after the cooking.

  After the cooking is finished, the control device 80 displays a cooking end message on the operation panel 11 and further sounds a signal by a buzzer (not shown) provided on the operation panel 11. Thereby, when the user who knows the end of cooking opens the door 12, the control device 80 detects that the door 12 has been opened by a sensor (not shown), and instantly opens the damper 68 of the exhaust passage 67. . Thereby, the first pipe 61 of the circulation path 60 communicates with the exhaust duct 65 through the exhaust passage 67, and the steam in the heating chamber 20 is blown by the blower fan 28 through the suction port 25, the first pipe 61, the exhaust passage 67 and The gas is discharged from the exhaust port 66 through the exhaust duct 65. This damper operation is the same even if the user opens the door 12 during cooking. Therefore, the user can safely remove the object to be heated 90 from the heating chamber 20 without being exposed to steam.

  According to the steam cooker 1 configured as described above, when the water tank 30 for storing water to be supplied to the steam generator 40 is stored in or taken out of the water tank storage unit 100, the water inlet 30a of the water tank 30 and If the connection with the receiving port 31 a of the water tank storage unit 100 is insufficient, water may overflow from the water supply port 30 a of the water tank 30. At this time, the water tank storage portion 100 has a shape of a guide recess that covers at least the area below the receiving port 31a of the inserted water tank 30 except for the tank insertion port 100f side. Since the bottom surface portion 100c of the tank storage portion 100 is gradually lowered toward the tank insertion port 100f, the water leakage from the water tank 30 flows out to the tank insertion port 100f side without leaking into the main body casing 10. Therefore, even if water leaks from the water tank 30, it can be drained to the outside of the water tank storage unit 100 to prevent the occurrence of mold or the like due to the accumulated water, and the hygiene and handling can be improved.

  Further, by receiving the water flowing out from the tank insertion port 100f side of the water tank storage unit 100 by the drainage tank 110, the outside of the water tank storage unit 100 is not wetted. In addition, by making the drain tank 110 detachable, the drain tank 110 can be removed and the water accumulated in the drain tank 110 can be discarded, thereby improving the handleability.

  Further, the water flowing out from the tank insertion port 100f side of the water tank storage unit 100 is guided to the drainage tank 110 by the inclined portion 100d as the guide unit, so that the drainage tank 110 reliably receives the water leakage from the water tank 30. be able to. In addition, the guide part which guides the water from the inside of the water tank storage part 100 to the drainage tank is not limited to the inclined part, and may use a groove or a pipe.

  In the above embodiment, the water leaked from the water tank 30 was drained from the water tank storage unit 100 to the drain tank 110, but the water leaked from the water tank may be drained to the outside via a drain hose or the like.

  In the above embodiment, the dew condensation water generated in the circulation path 60 is drained into the heating chamber 20 via the drainage path (drainage pipes 71 and 72). Condensed water generated in the circulation path may be drained through the drain path.

  Moreover, in the said embodiment, although the steam generator 40 and the steam temperature rising apparatus 50 were provided and the steam cooker which heats and cooks a to-be-heated material with superheated steam was demonstrated, the steam cooker of this invention does steam. What is necessary is just to be provided with the steam generator which generate | occur | produces, the tank which stores the water for supplying to the said steam generator, and the tank storage part which stores the said tank detachably.
