The length of the storage tank 16 in the insertion / extraction direction) can be easily expanded, and the volume of the storage tank 16 can be easily expanded without changing the projected area in the insertion / extraction direction. Thereby, the enlargement of the storage tank 16 and the increase in the amount of water to be stored can be easily realized.

  In addition, since the heating cookers 1, 1 </ b> A, 1 </ b> B, and 1 </ b> C according to the present embodiment include the frame 56 or the holder 53 </ b> A as a protective wall inside the opening 50 of the side wall 52, It is possible to prevent intrusion and prevent damage to the electric circuit in the storage room 40, accidents of the user, and the like, thereby improving safety.

  Furthermore, since the heating cookers 1B and 1C according to the present embodiment include the conducting wire 61 connected to the control device 62 from the input device 15 through the opening 50 of the sidewall 52, an additional opening used for laying the conducting wire 61 is provided on the sidewall 52. The strength of the tray 4 can be easily maintained.

  Furthermore, since the heating cookers 1A and 1C according to the present embodiment include the holder 53A that conceals the opening 50 of the side wall 52, the user can be prevented from touching the opening 50 of the side wall 52 and safety can be improved. .

  Moreover, the heating cookers 1B and 1C according to the present embodiment are controlled even if water leaks in the storage tank 16 or the electric pump 47 by positioning the control device 62 above the storage tank 16 and the electric pump 47. Does not impair the soundness of the device.

  Therefore, according to the heating cookers 1, 1A, 1B, and 1C according to the present embodiment, the storage tank 16 that stores the water for generating steam is easily used in the cooking device that cooks the object to be heated O using steam. Can be enlarged.
