However, by installing the tank 8 at a position of heat that escapes to the housing side, the heat can be used for heating the water in the tank 8, and the steam generation speed can be increased and at the same time the temperature rise of the housing can be prevented. It has the dual effect of being able to. In addition, by installing a part of the pipe 12 directly above the heater 9, there is an effect that the water for steam generation can be warmed and the speed of steam generation can be further increased.

  A convection case 14 is installed outside the back surface 2 c of the heating chamber 2. The convection case 14 includes a convection fan 17 powered by a convection heater 15 and a convection motor 16. A punching hole 18 for communicating the heating chamber 2 and the convection case 14 is formed on the back surface 2 c of the heating chamber 2. By driving the convection fan 17, air in the heating chamber 2 is sucked from the punching hole 18, heated by the convection heater 15, and blown again into the heating chamber 2 from the punching hole 18 to mainly perform convection heating.

  The water introduced into the heating chamber 2 is vaporized by radiant heating of the heater 9 or convection heating by the convection heater 15 and rides on the air current of the convection fan 17 installed on the back of the heating chamber 2 so that the inside of the heating chamber 2 is evenly distributed. Circulate. In particular, steam generated on the square plate 6 for steam generation is sucked from the punching hole 18 at the center of the back surface 2c of the heating chamber 2 and is reheated by the convection heater 15, so that the temperature of the steam is efficiently increased and exceeds 100 ° C. It is also possible to superheat steam.

  In addition, high-frequency heating means for performing dielectric heating may be provided in the main body 1. For example, as shown in the figure, a magnetron 19 is provided at the bottom of the heating chamber 2, and a microwave oscillated from the magnetron 19 is propagated into the heating chamber 2 via a waveguide 20 and a rotating antenna 22 driven by a motor 21. Let And the water of the square plate 6 for vapor | steam generation is heated and vaporized with this microwave. In addition, in the figure, although the structure which a microwave oscillates from the bottom part of the heating chamber 2 is shown, it is not restricted to this. For example, a high-frequency heating means may be provided on the side of the heating chamber 2 and another heater for radiant heating may be provided in the lower portion of the heating chamber 2.

  The food to be placed on the square dish 5 in the heating chamber 2 and the water in the steam generating square dish 6 use at least one of the above-described three heat sources of radiant heating, convection heating, and dielectric heating. Heated. What is necessary is just to make it select suitably the heat source to utilize according to a cooking menu.

  Next, the configuration of the steam generating square pan 6 will be described. As shown in FIG. 6, a groove 24 is formed on the peripheral edge 23 of the square dish 6 over the entire circumference, and is provided as a water channel for water flowing from the pipe 12. Moreover, the recessed part 25 connected to the groove part 24 is formed in several places, and water is supplied to the square plate 6 directly from the groove part 24 or along the recessed part 25. FIG. Thereby, water can be spread over the square plate 6 quickly in a wide range. Moreover, since water is supplied to the square plate 6, it is possible to remove water with a relatively large surface area, and there is an effect of further increasing the speed of steam generation and warming of the steam generation water. In addition, an operation portion 26 for operating the opening / closing of a pipe opening / closing valve, which will be described later, is provided on one side of the steam generating square dish 6, and in the first embodiment, it is constituted by two rod-like protrusions.

  In the first embodiment, an example in which the groove 24 and the recess 25 are formed in the peripheral edge 23 of the steam generating square dish 6 is not limited to this. For example, the peripheral edge 23 is inclined inward. You may make it make it.

  As shown in FIGS. 8 to 11, an opening 2 d is formed in the portion of the heating chamber 2 side surface 2 a to which the pipe 13 is connected, and a pipe opening and closing valve 27 indicating a pipe opening and closing mechanism is provided in the opening. Yes. In a state where the steam generating square pan 6 is not inserted to the back side of the heating chamber 2, the pipe opening / closing valve 27 is closed and water cannot be supplied to the heating chamber 2. FIG. 9, FIG. 10, and FIG. 11 show a state in which the steam generating square pan 6 is pushed into the inner side of the heating chamber 2. As shown in the figure, as the steam generating square pan 6 is inserted into the inner side of the heating chamber 2 by the operation unit 26 provided in the steam generating square pan 6, the pipe on-off valve 27 is gradually rotated. Go. When installed completely on the back side, the pipe opening / closing valve 27 is supported by the operation portion 26, the opening 2d is completely opened, and water can be supplied from the pipe 12. What is necessary is just to make it set beforehand according to a cooking menu, for example, the quantity of water thrown in from the pipe 12, the frequency | count of throwing in, etc., for example. In addition, the timing of charging may be such that the temperature in the heating chamber 2 is detected and water is charged based on the detection result. In addition, it is possible to detect the driving of the pipe opening / closing valve 27 and supply water.

  The water introduced from the pipe 12 flows into the groove 24 formed in the peripheral portion 23 of the steam generating square pan 6, and the water travels through the groove 24 or the concave portion 25 of the steam generating square pan 6, and the steam generating square pan 6 is supplied onto the square plate 6 from the periphery of 6. Thereby, since water can be applied to a relatively large surface area, there is an effect of further increasing the efficiency of warming water for generating steam and the speed of generating steam.

  Next, the operation will be described. FIG. 12 is a flowchart showing a cooking procedure. First, a square plate 5 on which an object is to be cooked and a square plate 6 for steam generation are installed in the heating chamber 2 and a tank 8 containing water is installed (S1 to S3). And when a steam utilization menu is selected in the operation part 4, steam utilization cooking is started (S4). When the installation state of the steam generating square pan 6 is incomplete, the pipe opening / closing valve 27 is not opened. Therefore, it is determined whether or not the pipe opening / closing valve 27 is opened (S5). A steam sensor (not shown) in the heating chamber 2 detects that steam is not generated, and notifies the user that cooking is being performed in an incomplete state (S6). When the steam generating square pan 6 is installed at a predetermined position, the amount of water corresponding to the cooking menu is poured from the pipe 12 into the square pan 6 (S7). Then, heating is started by energizing at least one of the heater 9, the convection heater 15, and the magnetron 19. The heating means heats the cooked food, generates steam, and is cooked using the generated steam.

  Here, for example, “yakisoba” is shown as an example of cooking. First, loosen noodles are placed on a square plate 5, vegetables and meat are spread on the noodles and sprinkled with yakisoba sauce, and the square plate 5 is placed in the heating chamber 2. The square plate 6 is also installed at a predetermined position in the heating chamber 2 and water is poured into the square plate 6. While heating with the convection heater 15 so that the inside of the heating chamber 2 may be about 200 degreeC-250 degreeC, the water of the square pan 6 for vapor | steam generation is heated and vaporized. By giving heat and appropriate moisture to the yakisoba, the noodles are stirred after heating for about 20 minutes.

  In addition, in the case of cooking that does not require steam generation, water is not poured into the square dish 6, but the square dish 6 can be used as a general cooking dish because it has a structure on which food can be placed. Therefore, for example, two-stage simultaneous convection heating cooking by the convection heater 15 is possible using the square dish 5 and the square dish 6.

  In addition, since the square plate 6 can be used as a plate on which the food is placed or as a plate for generating steam, water is poured into the square plate 6 with the food being placed on the square plate 6. And it is also possible to cook using steam only with the square plate 6. For example, “tea bowl steaming” is one of the steam use menus that can be cooked only with the square plate 6.

  As described above, according to the first embodiment, since water to be steam is introduced onto the steam generating square dish 6, a heater or a container dedicated to steam generation is not necessary, and the manufacturer aims to reduce the manufacturing cost. be able to. In addition, the user has the effect of improving the cleanability in the heating chamber 2. In addition, since water is poured onto the square plate 6 only in a state where the steam generating square plate 6 is installed at a predetermined position, water is not accidentally spilled into the heating chamber 2. Furthermore, since water is introduced by installing the steam generating square dish 6 in the heating chamber 2, the complexity during use can be eliminated and the usability is improved.
