Since it is equipped with the lifting drive means 20 for moving up and down, for example, when washing rice and water are added, the heavy rice cooker 2 that is 20 kg or more is put into the upper heating chamber 3 at the upper or lower position, or heavy rice cooking. The operation of taking out the pot 2 from the upper and lower heating chambers 3 becomes easy, and the burden on the operator can be reduced. That is, for example, when the rice cooker 2 is put in and out of each heating chamber 3, it is not necessary for the operator to lift the rice cooker 2 to the chest level or to lower it to the knee level, thereby reducing the burden on the operator. it can.

  Further, when the placing body 52 of the placing elevating means 19 is supported from below by the open / close door 18, the placing body 52 is not wobbled because the rice cooker 2 is put in and out of the heating chamber 3. The taking in and out operation can be performed easily and stably.

  Furthermore, since the placing body 52 of the placing elevating means 19 is supported on the work table 90 from below, the placing body 52 is wobbled because the rice in the rice cooker 2 is placed on the transporting container 91. Therefore, the cooking operation can be performed easily and stably while the rice cooker 2 is placed on the mounting table 77 of the mounting body 52.

  It should be noted that the lower surface of the base body 78 of the mounting base portion 77 of the mounting body 52 contacts the base support surface 45 of the open / close door 18 in an open state and is supported from below by the base support surface 45. If it is in a state, a simple work that can be performed in the rice cooker 2 taken out from the heating chamber 3 onto the mounting table 77, that is, for example, a process of spreading freshly cooked rice and sprinkling seasonings The mounting body 52 is not wobbled even when the mounting lifting means 19 is stopped at the middle loading / unloading stop position instead of being supported from below by the work table 90, and can be performed easily and stably.

  Further, since the mounting body 52 can be rotated in the vertical direction with respect to the elevating body 51, for example, the mounting body 52 can be easily rotated to a position where it does not interfere with the open / close door 18.

  Further, the mounting body 52 is cantilevered by only one support arm portion 71 provided on the lifting body 51 so as to be pivotable in the vertical direction, and provided at the tip of the support arm portion 71. Since the mounting table portion 77 is supported, the number of parts can be reduced and the configuration can be simplified as compared with, for example, a configuration in which the mounting table portion is supported by a pair of left and right support arm portions. .

  Further, the mounting lifting means 19 is for a work table that outputs a descent stop signal by contact with the work table 90 and a door descent stop switch 83 that outputs a descent stop signal by contact with the open / close door 18. Since the descent stop switch 86 is provided, the mounting elevating means 19 can be appropriately stopped at a desired position.

  In the above-described embodiment, the configuration in which the mounting elevating means 19 has the separate switches 83 and 86 has been described. However, for example, the configuration having only one lowering stop switch that also serves as both the switches 83 and 86 may be used. Good. Further, for example, a configuration having only a descent stop switch 83 that outputs a descent stop signal by contact with the open / close door 18 may be used.

  Further, the switches 31, 34, 61, 83, 86 are not limited to those made of, for example, contact type limit switches, but may be made of, for example, an optical sensor or the like. Further, for example, the control means may detect the load of the drive motor 28 and stop the drive motor 28.

  Further, for example, a covering means such as a cover plate may be attached to the left side plate portion 21 of the apparatus main body 17 so as to cover the rotating shaft 26 and the elevating body 51 with the covering means.

  Further, the number of heating chambers 3 of the apparatus main body 17 is arbitrary, and may be two or four or more, and may be configured to have one heating chamber 3 positioned at the chest height or knee height of the operator. .
