  The heating / cooking apparatus 10 includes a rectangular box-shaped housing 11, a rectangular cooking cabinet 20 disposed in the housing 11, and containing an object to be cooked, and a heater unit 30 disposed in the cooking cabinet 20. And a boiler (steam generator) 40 arranged in the cooking cabinet 20, and a control unit 100 for controlling operations of the heater unit 30 and the boiler 40.

  An opening / closing lid 12 is provided on a front surface of the housing 11, and an operation unit 13 is provided on a front surface of the opening / closing lid 12. The operation unit 13 is provided with an input unit 14 for setting a heating time and switching a cooking mode, and a notification unit 15 such as an LED and a buzzer.

  A water tray (water supply unit) 21 is provided above the cooking cabinet 20. A hole 21 a is formed in the bottom of the water receiving tray 21. Further, a cylindrical water guide path 50 for guiding water W from the water receiving tray 21 to a boiler container 41 described later is provided inside the housing 11. The water guide path 50 is a first guide portion 51 that guides obliquely downward from the bottom of the water receiving tray 21 toward the upper side of the outer side of the cooking chamber 20, and a vertical direction from the upper side of the outer side of the cooking chamber 20 to the lower side of the outer side. And a second guide portion 52 leading to the boiler container 41. The first guide portion 51 has an opening 51 a and is arranged to face the hole 21 a of the water receiving tray 21. The first guide portion 51 and the second guide portion 52 are formed along the wall surface of the cooking cabinet 20, and are formed so that heat in the cooking cabinet 20 is easily transmitted.

  The water guide path 50 is detachable, and can be easily cleaned by removing it from the cooking cabinet 20 as shown in FIG.

  The water tray 21 can store a predetermined amount (for example, 10 cc) of water W. In the middle of the cooking cabinet 20, a metal grill 22 on which an object to be cooked is placed is provided substantially horizontally. Further, a cooking thermistor (temperature sensor) 24 is provided in the cooking cabinet 20.

  The heater section 30 includes an upper surface heater 31 arranged at an upper part in the cooking cabinet 20 and a lower surface heater 32 arranged at a lower part.

  The boiler 40 includes a boiler container 41 located below the grill 22, a boiler heater 42 for heating the boiler container 41, and a boiler thermistor (temperature sensor) 43 attached to the boiler container 41. ing. The capacity of the boiler container 41 has a predetermined amount (for example, 10 cc) or more.

  The control unit 100 independently energizes the control device 110 that performs operation commands, calculations, and detections according to a program for executing a predetermined heating cooking flow, and the upper surface heater 31, the lower surface heater 32, and the boiler heater 42, respectively. And a power supply device 120 for performing the operation.

  The control device 110 is provided with inputs from the in-chamber thermistor 24 and the boiler thermistor 43, inputs from the input unit 14, outputs to the notification unit 15, and outputs to the power supply device 120.

  The power supply device 120 is provided with a first relay 121, a second relay 122, and a third relay 123 connected to the upper heater 31, the lower heater 32, and the boiler heater 42, respectively.

  In the cooking device 10 configured as described above, cooking is performed as follows. First, the lid 12 is opened, and a predetermined amount of water W is poured into the water tray 21. The water W poured into the water tray 21 is guided to the boiler container 41 through the water guide path 50. The water W adheres to the water guide path 50 to some extent. Next, an object to be cooked such as a toast is placed on the grill 22 and the opening / closing lid 12 is closed.

  Set the cooking mode and timer. The timer setting can set an arbitrary time between a minimum of 1 minute and a maximum of 15 minutes to adjust the density of the grill. Thereby, the heating cooking is started, and the boiler control and the heating control are performed.

  In the boiler control, first, the third relay 123 is operated, and when the boiler heater 42 is energized, the water W in the boiler container 41 is heated and becomes steam to fill the cooking chamber 20. The steam covers the object to be cooked. In the state where the water W remains, the temperature of the boiler thermistor 43 does not exceed 100 ° C. When all of the water W evaporates and runs out of water W, the temperature of the boiler container 41 rises sharply, and when the temperature of the boiler thermistor 43 reaches 120 ° C. or higher, it is determined that the water W has run out. The third relay 123 is opened for the device 120, and the power supply to the boiler heater 42 is stopped.

  In the heating control, the first relay 121 and the second relay 122 are operated in a heating pattern according to the selected cooking mode, and the upper heater 31 and the lower heater 32 are energized to start heating cooking.

  When the timer setting time (for example, 10 minutes) elapses from the start of heating, the power supply to the upper surface heater 31 and the lower surface heater 32 is stopped, and the heating cooking is ended.

  The water supplied from the water receiving tray 21 to the boiler container 41 before the start of heating and adhered to the water guide path 50 evaporates when the cooking cabinet 20 becomes high temperature within the heating time and remains as water. Never.

  As described above, the cooking device 10 according to the present embodiment can perform cooking using steam. Further, the water poured into the water receiving tray 21 and adhering when passing through the water guide path 50 is adjacent to the cooking chamber 20 which has become high in temperature during the heating and cooking, so that all the water evaporates and remains as water. Absent.

  For this reason, it is possible to maintain the sanitary condition of the device and prevent the device from corroding without water spoiling or corroding the material forming the water guide path 50. Therefore, troubles such as washing and discarding and drying water are not required.

  As described above, according to the cooking device 10 according to the present invention, while having the steam function, the water in the supply path from the water supply unit to the boiler is not left, so that the sanitary state of the device is maintained, and the corrosion of the device is maintained. Can be prevented.

The present invention is not limited to the above embodiment. For example, although the boiler 40 is used as the steam generator in the above-described example, the steam may be generated using an ultrasonic generator. Although the water receiving tray 21 is shown as the water supply unit, a water tank that can stop the water supply after the cooking is stopped may be used. Further, the configuration and the like of the heater unit 30 may be appropriately changed according to the size and shape of the cooking cabinet 20, the type of the object to be cooked, and the like. In addition, it is given Ru course der various modifications may be implemented without departing from the scope of the present invention.
