Description

  The present invention relates to a cooking device including a heating chamber and a tray that is disposed in the heating chamber and supports an object to be heated.

  2. Description of the Related Art Conventionally, as a cooking device tray, there is a turntable that is provided on a bottom plate of a heating chamber, on which an object to be heated is placed, and that rotates about a central rotation axis in a plan view (for example, JP-A-2- 306030 gazette: see Patent Document 1). A heating cooker including this turntable includes an upper heater disposed on the ceiling of the heating chamber and a lower heater disposed on the back side of the bottom plate of the heating chamber, and rotates an object to be heated on the turntable. Thus, uneven heating of the object to be heated is prevented in plan view.

  However, since the lower heater is separated from the bottom plate in the conventional turntable as the above-mentioned cooker tray, it is difficult to transfer the heat from the lower heater to the object to be heated. There is a problem that uneven heating occurs.

  Conventionally, as a tray for a heating cooker that can solve such a problem, there is a tray used for a heating cooker that heats an object to be heated with steam (see, for example, Japanese Patent Application Laid-Open No. 2003-302051: Patent Document 2). The tray for the heating cooker is a turntable provided on the bottom plate of the heating chamber, is equipped with a waist-high grill net, and an object to be heated is arranged on the grill net. The object to be heated is disposed between the steam outlets provided at the upper and lower portions of the heating chamber by the waist-high grill net. Thereby, the steam from the steam outlet is sent to the upper side and the lower side of the object to be heated, so that uneven heating between the upper side and the lower side of the object to be heated is prevented.

However, the tray for the heating cooker has a problem that handling is troublesome because it is necessary to mount a grill net before cooking the object to be heated. In addition, since it is necessary to clean the grill net after cooking, there is a problem that it takes time and effort for maintenance. In addition, when cooking is performed by heating the object to be heated only from the upper side, the object to be heated is directly disposed on the turntable, so that the grill net is not necessary and is disposed outside the heating cooker. Therefore, it is necessary to secure an arrangement space for the grill net outside the heating cooker, and there is a problem that the grill net arranged outside the heating cooker gets in the way and gives a complicated impression.

Connected to the steam outlet 22.

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

  The control device 80 is composed of a microcomputer, an input / output circuit, and the like. As shown in FIG. 6, the blower fan 28, the first steam heater 52, the second steam heater 53, the damper 68, the drain valve, as shown in FIG. 70, steam generating heater 42, operation panel 11, water tank water level sensor 36, water level sensor 43, temperature sensor 81 for detecting the temperature in the heating chamber 20, and humidity in the heating chamber 20. The humidity sensor 82 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, operation | movement of the heating cooker 1 which has the said structure is demonstrated. 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 in a state where the exhaust passage 67 is 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 heating 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 and 2nd steam heater 52,53, 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. Further, other portions of the superheated steam are ejected from the steam outlets 22 on both side surfaces of the heating chamber 20 through the steam supply passages 23 provided on the left and right sides of the steam temperature raising device 50.

  As shown by the arrows in FIG. 4, the superheated steam ejected from the left and right side surfaces of the heating chamber 20 is partially transferred from the through hole 4 f serving as the first through hole facing the steam outlet 22 of the tray 4 to the tray 4. And the other part flows to the upper side of the tray 4. Thus, the superheated steam ejected from the steam outlets 22 on both sides of the heating chamber 20 is supplied to the upper side and the lower side of the tray 4. When a sufficient amount of steam is supplied to the lower side of the tray 4, the through holes 4 f are formed as second through holes provided on the front and back edges of the tray 4 when viewed from the opening 20 a side of the heating chamber. Thus, a flow from the lower side to the upper side of the tray 4 is generated.

  Thus, on the upper side of the tray 4 in the heating chamber 20, a flow of steam that blows down at the center and rises at the outside is generated. In addition, on the lower side of the tray 4 in the heating chamber 20, steam flows from the left and right to the front and rear. Then, the steam on the upper side of the tray 4 is sequentially sucked into the suction port 25 and repeats circulation such that it returns to the heating chamber 20 through the external circulation path 60 again.

  In this manner, the flow of superheated steam is formed on both the upper side and the lower side of the tray 4 in the heating chamber 20, thereby maintaining the temperature / humidity distribution in the heating chamber 20 uniformly. The upper object 90 can be heated from both the upper and lower sides. As a result, the upper and lower sides of the object to be heated 90 can be heated without unevenness.

  Further, the superheated steam on the lower side of the tray 4 is returned to the upper side of the tray 4 through the through holes 4f on the opening 20a side and the back side surface 20b of the heating chamber, so that a new lower side of the tray 4 is provided. Superheated steam can be supplied efficiently. Accordingly, the object to be heated 90 can be efficiently heated also from the lower side of the tray 4.

  In addition, when 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.

  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 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, and the exhaust passage 67. Then, the gas 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 remove the object to be heated 90 from the heating chamber 20 without being exposed to steam.

  As described above, according to this embodiment, the tray 4 is locked to the locking portions 3 on the left and right side surfaces of the heating chamber 20, and the through hole 4 f of this tray is opposed to the steam outlet 22. Thus, the object to be heated 90 can be heated without unevenness without using a conventional waist-high grill net. Therefore, it is possible to save the trouble of installing the grill net in the heating chamber before cooking, and maintenance can be facilitated because only the tray 4 needs to be cleaned after cooking.

  In the above embodiment, the tray 4 is locked to the locking portion 3 and heated from both the upper and lower sides of the tray 4. However, when heating is performed only from the upper side of the tray 4, the tray 4 is heated to the bottom surface 20 d of the heating chamber 20. Should be arranged. In this case, it is not necessary to secure a place for disposing the unused grill net as in the prior art, and the unused grill net does not disturb and give a complicated impression.

  Moreover, in the said embodiment, although the latching | locking part 3 was provided below the steam blower outlet 22, you may provide the latching | locking part 3 above the steam blower outlet 22. FIG. In this case, the tray 4 of the present embodiment is locked to the locking portion 3 in the reverse direction so that the through hole 4f of the tray is opposed to the steam outlet 22 and the steam from the steam outlet 22 is reduced. The portion can be supplied to the upper side of the tray 4 through the through hole 4f of the tray, and the other part of the steam can be supplied to the lower side of the tray 4.

  Moreover, in the said embodiment, although the through-hole 4f was provided in the vicinity of the four sides of the tray 4, when it arrange | positions in the heating chamber 20, the through-hole 4f located in the opening 20a side of a heating chamber, and a back side surface Any one of the through holes 4f located on the 20b side may be deleted. Further, the number of through holes 4f formed in the vicinity of each side is not limited to four and may be any number. The shape of the through hole 4f is not limited to a rectangle, and can be any shape such as a square, a circle, or an ellipse.

  Further, the steam may be supplied into the heating chamber 20 only by the steam outlets 22 on both the left and right sides without providing the ceiling steam outlet 55.

In this embodiment, superheated steam at about 300 ° C. at 1 atm is used as the heating fluid. However, other than superheated steam, it does not fall within the scope of the present invention, but steam at about 100 ° C. at 1 atm is used. You can also. Further, not limited to steam, high-temperature air may be used as a heating fluid. In short, as long as an object to be heated can be heated, other heating fluids such as gas and liquid can be used.
