Description

  The present invention relates to a cooking device for cooking food using steam and a rack used in the cooking device.

  2. Description of the Related Art Conventionally, there is a cooking device with a steam generator disclosed in Japanese Patent Application Laid-Open No. 4-123790 (Cited Document 1) as a cooking device that uses steam to cook an object to be heated such as food. This cooking device with a steam generator includes a heating chamber, an induction heating coil, a tank, a water tank, an on-off valve, and a port. Then, after evaporating water is supplied to the water storage tank and the on-off valve is opened to fill the tank with water, an alternating current is passed through the induction heating coil, and the tank is heated by an alternating magnetic field generated in the coil. Steam is generated, and the generated steam is sent into the heating chamber from the port provided on the side wall of the heating chamber. Thus, cooking is performed on an object to be heated placed on a tray positioned below the position of the port.

  However, the cooking device with a steam generator disclosed in the above cited document 1 has the following problems. That is, the port for sending steam into the heating chamber is above the position of the tray on which the object to be heated is placed. Therefore, there is no problem in the case of steaming the object to be heated. However, when the object to be heated is heated by steam, it is only necessary to spray steam from above on the object to be heated. Cannot be wrapped with steam, and the heating rate is slow.

  In the heating cooker with a water vapor generator, a waveguide opening is provided at the top of the heating chamber, while a magnetron is provided at the end of the waveguide opposite to the opening, The cooking of the object to be heated on the tray is also possible by the microwave.

Therefore, in order to shorten the heating time by the steam from the port, it is conceivable that the steam is blown out from the upper part of the heating chamber instead of the steam from the port instead of the microwave. However, the tray on which the object to be heated is placed is placed on a turntable provided at the bottom of the heating chamber. Therefore, the steam blown from the upper part of the heating chamber far from the steam outlet provided in the upper part of the heating chamber does not reach the object to be heated and does not contribute to an increase in the heating rate.

  Next, the control system of the heating cooker 1 will be described.

  The control device 80 includes a microcomputer, an input / output circuit, and the like, and as shown in FIG. 4, the blower fan 28, the first steam heater 52, the second steam heater 53, the damper 68, and the drain valve. 70, the steam generating heater 42, the operation panel 11, the water tank water level sensor 36, the water level sensor 43, the temperature sensor 81 for detecting the temperature in the heating chamber 20 (shown in FIG. 3), and the heating chamber 20 A humidity sensor 82 for detecting the humidity inside the pump and the pump 35 are connected. Based on the detection signals from the water tank water level sensor 36, the water level sensor 43, the temperature sensor 81, and the humidity sensor 82, the blower fan 28, the first steam heater 52, the second steam heater 53, the damper 68, the waste water. The valve 70, the steam generating heater 42, the operation panel 11 and the pump 35 are controlled according to a predetermined program.

  Hereinafter, the operation of performing cooking with the cooking device 1 having the above configuration will be described with reference to FIGS. 3 and 4. When a power switch (not shown) of the operation panel 11 is pressed, the power is turned on, and the cooking operation is started by operating the operation panel 11. Then, first, the control device 80 closes the drain valve 70 and starts the operation of the pump 35 with the exhaust passage 67 closed by the damper 68. Then, water is supplied from the water tank 30 into the pot 41 of the steam generator 40 via the first to fourth water supply pipes 31 to 34 by the pump 35. Thereafter, when the water level sensor 43 detects that the water level in the pot 41 has reached a predetermined water level, the pump 35 is stopped to stop water supply.

  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.

  When the steam generating heater 42 is energized 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 and second steam heaters of the steam temperature raising device 50 are turned on. Energize 52 and 53. 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 external circulation path 60. In that case, since the centrifugal fan is used for the ventilation fan 28, a high pressure can be generated compared with the case where a propeller fan is used. 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 external circulation path 60 at the location of the steam suction ejector 44. Then, the steam discharged from the steam suction ejector 44 flows into the steam temperature raising device 50 through the third pipe 63 at a high speed.

  And the steam which flowed into the said steam temperature rising apparatus 50 is heated by the 1st, 2nd steam heating heaters 52 and 53, and becomes a superheated steam of about 300 degreeC (it changes with cooking contents). A part of this 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. In addition, the other part of the superheated steam is provided on the side steam outlets 22 disposed below the interrupting portions on both side surfaces of the heating chamber 20 via the steam supply passages 23 provided on the left and right sides of the steam heating device 50. Erupted from.

  Thus, the superheated steam ejected from the ceiling side of the heating chamber 20 is vigorously supplied toward the heated object 90 side in the center. At the same time, the superheated steam ejected from the lower side of the rack 24 on the left and right side surfaces of the heating chamber 20 is supplied while rising so as to wrap the heated object 90 from below the heated object 90. As a result, in the heating chamber 20, convection occurs in such a manner that it blows down at the center and rises outside thereof. Then, the convection steam is sequentially sucked into the suction port 25 and repeatedly circulates through the external circulation path 60 and returns to the heating chamber 20 again.

  In this way, by forming a convection of superheated steam in the heating chamber 20, the superheated steam from the steam heating device 50 is blown to the ceiling steam while the temperature and humidity distribution in the heating chamber 20 is kept uniform. It is possible to eject the gas from the outlet 55 and the side outlet 22 and to efficiently collide with the heated object 90 placed on the rack 24, and the heated object 90 is heated by the collision of the superheated steam. In that case, the superheated steam that has contacted the surface of the object to be heated 90 also heats the object to be heated 90 by releasing latent heat when the surface of the object to be heated 90 is condensed. As a result, a large amount of heat of the superheated steam can be reliably and promptly applied to the entire surface of the article 90 to be heated. Therefore, it is possible to realize high-speed cooking with no spots and good finish.

  In addition, when the time elapses during the cooking operation, 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 that time, the steam 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 cooking, the control device 80 displays a cooking end message on the operation panel 11, and a buzzer (not shown) provided on the operation panel 11 sounds a signal. When a user who knows the end of cooking by these messages and buzzer opens the door 12, the control device 80 detects that the door 12 has been opened by a sensor (not shown) and opens the damper 68 of the exhaust passage 67. Open instantly. Then, the first pipe 61 of the external circulation path 60 communicates with the exhaust duct 65 via 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, and the exhaust passage 67. And is discharged from the exhaust port 66 through the exhaust duct 65. This damper operation functions similarly even if the user opens the door 12 during cooking. Therefore, the user can safely take out the object 90 to be heated from the heating chamber 20 without being exposed to steam.

  Hereinafter, as described above, the superheated steam ejected downward from the ceiling side of the heating chamber 20 and the superheated steam ejected from below the racks 24 on the left and right side surfaces of the heating chamber 20 rise. The structure of the heating chamber 20 that wraps the article 90 to be heated on the rack 24 and enables efficient and high-speed cooking will be described in detail.
