[0002]

2. Description of the Related Art An example of a conventional cooking device such as a microwave oven will be described with reference to FIG. FIG. 6 is a vertical sectional view of the microwave oven. Numeral 31 denotes an oven cabinet. At the time of high-frequency heating, high-frequency electromagnetic waves generated by the high-frequency oscillator 32 are supplied into the oven cabinet by the waveguide 33, and the food 34 on the food placing plate 35 is heated. When the oven is heated, the heater 45 for heating the oven storage is used.
The food 34 is heated by the heat generated by the infrared radiation or convection heat transfer. However, in the above configuration, for example, in the case of reheating rice, there is a disadvantage that as the food is heated, moisture in the food evaporates, and the food surface is dried and hardened.

[0003] To compensate for such a drawback, a steam microwave oven has been proposed. FIG. 7 is a vertical sectional view of a steam microwave oven. In addition to the configuration of the microwave oven shown in FIG. 6, a steam generator 4 having a water tank 43 and a heater 41 is shown.

Further, the water in the steam generator 42 is converted into steam 44 by the heater 41 and released into the oven 36 to prevent the food from drying during heating and cooking.

In the case of reheating fried food,
The food was heated while the water content on the food surface increased due to the transfer of moisture to the food surface due to the evaporation of the food moisture at the center of the fry, and the decrease in the evaporation rate from the food surface due to the increase in humidity in the oven.

The supply of water to 2 and the treatment of drain water are complicated.

[0006] When reheating fried food, etc.,

Embodiment 1 This embodiment will be described below with reference to FIG.

In FIG. 1, reference numeral 1 denotes an oven cabinet having a suction port 3 and a blow-out port 4 for storing food therein and sealed by a door 2, and 5 denotes a communication between the suction port 3 and the blow-out port 4. It is a circulating airway. In the circulation air passage 5, an adsorbent 6 such as silica gel or zeolite,
A blower 7 for sending air to the adsorbent 6 and a heat source 8 such as an electric heater for supplying thermal energy to the adsorbent 6 are provided. Electric power is supplied to the blower 7 and the heat source unit 8 from a power supply unit 9, and a cooking method of performing “humidifying heating cooking” or “dehumidifying heating cooking” manually or based on information from a sensor is selected.

In the above configuration, when "humidifying and heating cooking" is selected by the cooking method selecting means 10, prior to cooking (at the end of cooking), the moisture absorbing step of absorbing moisture in the air to the adsorbent 6 is performed. Thereafter, a humidification heating cooking process is performed. That is, during the moisture absorption process, the cooking method selection means 10

When "dehumidification heating cooking" is selected by the cooking method selection means 10, a dehumidification heating cooking process is performed after a regeneration process of desorbing moisture from the adsorbent 6 prior to cooking. That is, in the regeneration process, the control unit 11 supplies power to the heat source unit 8 and operates the blower 7. In this case, the high-temperature air heated by the heat source unit 8 desorbs the moisture adsorbed by the adsorbent 6 when passing through the adsorbent 6, and becomes humid air from the oven chamber. Emitted when the door is opened.
In the dehumidifying cooking process, the controller heats the food by operating the blower 7 while controlling the heat source 8 so that the temperature of the wind sent from the heat source 8 does not cause the adsorbent 6 to be desorbed, Vapor generated from food during cooking is guided from the suction port 3 to the adsorbent 6, and absorbed by the adsorbent 6, thereby suppressing the humidity in the oven chamber and realizing dehumidifying heating cooking.

In 0 seconds, 40 g of water can be desorbed. Then, the desorbed water vapor is sucked in from the suction port 3 and sent into the oven chamber from the blowout port 4 together with the air guided into the waveguide 14, and further passes through the waveguide 14 to the suction port 3. Alternatively, high-frequency waves supplied into the oven chamber using the blowout port 4 as a power supply port heats foods and the like, thereby realizing heating and humidification cooking.

When "dehumidification heating cooking" is selected by the cooking method selection means 10, a dehumidification heating cooking process is performed after a regeneration process of desorbing moisture from the adsorbent 6 prior to cooking. That is, in the reproduction process, the control unit 10

In the dehumidifying cooking process, the controller operates the blower 7 while controlling the high frequency output so that the adsorbent 6 is not desorbed, so that the high frequency is supplied from the suction port 3 or the outlet 4 to the oven chamber. Power is supplied to the inside, and water vapor generated from food at the time of heating is guided from the inlet 3 to the adsorbent 6 and absorbed by the adsorbent 6, thereby suppressing the humidity in the oven chamber to a low level, thereby realizing dehumidifying heating cooking.

Electric power is supplied from the power supply unit 9 to the blower 7 and the high-frequency supply unit 13, and a cooking method of performing “humidifying heating cooking” or “dehumidifying heating cooking” manually or based on information from a sensor is described. On the basis of a signal from the selected cooking method selecting means 10, the control unit 11 controls the power supply unit 9 and switches between the opening of the suction air passage switching unit and the opening of the blowing air passage switching unit.

In the above configuration, the cooking method selecting means 10
If "humidification and heating cooking" is selected, a humidification and heating cooking process is performed prior to cooking (at the end of cooking), after a moisture absorption process in which the adsorbent 6 adsorbs moisture in the air. That is,

The blower 7 is operated to adsorb moisture to the adsorbent 6.

Next, in the humidification heating cooking process, the control section 11 switches the suction air path switching section 17 to a position to open the suction port 16 indicated by a dotted line as shown in FIG. The humidifying and heating cooking is performed in the same manner as in the second embodiment, with 20 being a position where the outlet 4 indicated by a dotted line is opened.

When "dehumidification heating cooking" is selected by the cooking method selection means 10, the control unit 11 performs a dehumidification heating cooking process after a regeneration process of desorbing moisture from the adsorbent 6 prior to cooking. Let In the regeneration process, the control section 11 sets the suction air path switching section 17 and the blow air path switching section 20 to the positions indicated by the solid lines in FIG. 3 and reproduces the adsorbent in the same manner as in the second embodiment. Further, in the dehumidifying cooking process, the control unit 11 controls the suction air passage switching unit 17 and the blow air passage switching unit 20 as shown in FIG.

In the configuration in which the heating means is provided in the oven storage, humidification and dehumidification heating cooking under optimum heating conditions can be realized as described in the second embodiment.

Further, the circulation air passage and the waveguide may be provided separately. Embodiment 4 Another embodiment of the present invention will be described with reference to FIG. The present embodiment aims at dehumidifying / humidifying heating cooking for supplying the optimum moisture to the oven chamber in a short time. In addition to the configuration of the second embodiment, the suction from the blower 7 into the waveguide 14 is performed. The wind sent to the material 6 can be passed through,

When performing the humidification heating cooking, the control unit 11 performs the humidification heating cooking process based on the humidification heating cooking signal manually or automatically selected by the cooking method selection means 10, and then performs the humidification heating cooking process. Let it do. In the process of absorbing moisture, the control unit 11 operates the blower 7 without supplying electric power to the high frequency supply means 13 to cause the adsorbent 6 to adsorb moisture.
