Each heating chamber 2 is provided with an open / close sensor 17 that detects whether the open / close door 15 is in a fully closed state in which the opening 11 of the heating chamber 2 is closed or in a fully open state.

  The shuttle lifting mechanism 7 includes a shuttle support part 18 on which the shuttle K can be placed, and an elevator drive part 19 that can lower and raise the shuttle support part 18 in a substantially vertical direction.

  The raising / lowering drive part 19 consists of the raising / lowering base 20 and the drive means 21, and is arrange | positioned by the base | substrate 23 attached to one side surface 22 of the three-dimensional rice cooker main body 6. FIG. The base 23 has a rectangular plate shape, and the surface thereof is a flat mounting surface 24 so that the lifting drive unit 19 can be easily mounted, and the mounting surface 24 is a vertical surface on one side 22 of the three-dimensional rice cooker body 6. The lifting drive unit 19 can be installed on the three-dimensional rice cooker body 6 without distortion.

  The drive means 21 includes two lot rods 25, a spiral shaft 26, and a drive motor 27, each of which is attached to the attachment surface 24. The two lot rods 25 are in a parallel state in which both axial centers are separated by a predetermined distance, and the upper end portion 28 and the lower end portion 29 of each lot rod 25 support the bearing 30 so that the axial centers are vertical. It is fixed to the vicinity of both sides of the mounting surface 24. The spiral shaft 26 is located between the two lot rods 25 and the axis of the spiral shaft 26 is parallel to the axis of the lot rod 25, and the vicinity of the upper end portion 31 and the lower end portion 32 of the spiral shaft 26. Is fixed to the mounting surface 24 through a bearing 33 so as to be rotatable. The drive motor 27 is mounted near the upper end of the mounting surface 24 so as to be positioned above the spiral shaft 26 and so that the axis of the rotation shaft 34 of the drive motor 27 and the axis of the spiral shaft 26 are collinear. The rotation shaft 34 of the drive motor 27 and the spiral shaft 26 are connected via a transmission means, and the rotational force from the drive motor 27 is transmitted to the spiral shaft 26 to rotate.

  The elevating base 20 has a rectangular plate shape, and is disposed so that one flat surface 35 of the elevating base 20 faces the mounting surface 24 of the base 23, and is fixed to the mounting surface 24 of the base 23. Two parallel lot rods 25 and slidable bearings 36 are fixed to each other at two locations in the vertical direction. A bearing 37 that is rotatably engaged with the helical shaft 26 fixed to the mounting surface 24 is also fitted at one place so as to follow the movement of the elevating base 20. The two lot rods 25 fixed to the mounting surface 24 of the base 23 are passed through the holes of the slidable bearings 36 for the two parallel lot rods 25 and for the spiral shaft 26. The screw shaft 26 fixed to the mounting surface 24 of the base 23 is screwed into the screw hole of the bearing 37 to be screwed. Therefore, the lifting base 20 is supported by the two lot rods 25 so that the mounting surface 24 of the base 23 and one flat surface 35 of the lifting base 20 face each other at a constant interval while maintaining an equilibrium state in the vertical direction. And can be moved up and down by rotation of the spiral shaft 26.

  The elevating base 20 is rotatably connected to the hook support 18 from the other flat surface 38 of the elevating base 20 that does not face the mounting surface 24 of the base 23, that is, the front surface as the elevating base 20. The horizontal shaft 39 protrudes in the horizontal direction.

The shuttle support 18 includes a shuttle mounting table 40 and a support arm 41, and is connected to the lift base 20 so that it can be lifted and lowered in conjunction with the vertical movement of the lift base 20.

  The hook mounting table 40 is formed in a plate shape having the same size as the bottom plate portion 3 of the pot K, and has a pot mounting surface 42 whose upper part is a substantially horizontal flat surface. The pot K can be placed stably, and is disposed in the vicinity of the front surface of the three-dimensional rice cooker body 6. In addition, a guide plate 44 that prevents the pot K from sliding off the pot mounting surface 42 is projected upward on the edge 43 on the side separated from the three-dimensional rice cooker body 6 on the pot mounting surface 42. In addition, four rollers 45 with the axis oriented in the horizontal direction are mounted near the three-dimensional rice cooker body 6 side, and the upper part of the rollers 45 protrudes to the extent that it contacts the bottom plate 3 of the pot K. Thus, the hook can be easily moved on the hook mounting surface 42.

  The support arm 41 is formed by bending a hollow round pipe into an L shape, one end 46 is fixed to the lower part of the hook mounting table 40, and the other end 47 is connected to the lifting base 20. . At the other end 47, a cylindrical collar 48 having a hole in the center and the axis of the hole oriented in the horizontal direction is fixed, and the hole of the collar 48 is a horizontal axis 39 of the lifting base 20. It is inserted so that it can rotate freely. Accordingly, the support arm 41 is connected to the lifting base 20 so as to be rotatable in the vertical direction with the horizontal shaft 39 as a fulcrum, and protrudes forward of the three-dimensional rice cooker body 6 so as to mount the pot mounting table 40. It comes to support. Further, the hook mounting surface 42 of the hook mounting table 40 fixed to one end 46 of the support arm 41 is maintained in a substantially horizontal state, so that the support arm 41 moves downward with the horizontal shaft 39 as a fulcrum. A stopper 49 is attached to the elevating base 20 so as to prevent the support arm 41 from rotating downward from a predetermined position so that the tilted base 20 is not inclined.

  The hook mounting surface 42 of the hook mounting table 40 fixed to the lifting base 20 via the support arm 41 moves up and down in the vertical direction of the lifting base 20 from the upper heating chamber 2a to the lower stage. The space up to the heating chamber 2c is raised and lowered in the state of being close to the opening 11 of each heating chamber 2 in front of the three-dimensional rice cooker body 6.

  Further, when the hook K is carried in and out from the opening 11 of each heating chamber 2, it is substantially the same as the bottom plate portion 3 of the pot K in the state where the hook mounting surface 42 of the pot mounting table 40 is loaded into the heating chamber 2. The height is stopped. Therefore, on the mounting surface 24 of the base 23, when the hook mounting table 40 is moved to a position suitable for loading and unloading the pot K in the respective heating chambers 2, the hoisting table 40 is moved up and down. A position sensor 50 that detects the movement position of the base 20 is provided. The rotation of the drive motor 27 is stopped by the detection of the position sensor 50, so that the hook mounting table 40 can be stopped at a predetermined position. Further, a detection sensor for freely specifying the height of the hook mounting table 40 that moves up and down so that the operator can easily place the pot K on the pot mounting surface 42 and stopping the pot mounting table 40 there. (Not shown) is also provided. In the present embodiment, the height at which the worker can easily place the shuttle K on the shuttle mounting surface 42 is the same as the position suitable for loading and unloading the shuttle K in the middle heating chamber 2b. .

  The hook mounting table 40 vertically moves from a stop position for loading and unloading the pot K in the lower heating chamber 2c to a stop position for loading and unloading the pot K in the upper heating chamber 2a. In addition to this, by further raising the stop position in the upper heating chamber 2a, the support arm 41 can be rotated upward with the horizontal axis 39 of the elevating base 20 as a fulcrum. It moves so that it may invert toward the upper part of the type rice cooker body 6. For this reason, when the pot mounting table 40 is not required, such as after the end of the rice cooking operation, the pot mounting table 40 can be eliminated from the front of the three-dimensional rice cooker main body 6 to free up the space. .

  A reversing arm 51 coupled to and interlocked with the support arm 41 as means for moving the pot mounting table 40 while reversing it upwards above the three-dimensional rice cooker body 6 by rotating the support arm 41 upward. And a reversing stopper 52 attached to the attachment surface 24 of the base 23.

  The reversing arm 51 is formed in a rectangular plate shape. A roller 54 is rotatably fixed to one end side 53 and the other end side 55 is inserted into the horizontal shaft 39 of the elevating base 20. It is attached to the collar 48 of the supporting arm 41. In the reversing arm 51, when the hook mounting surface 42 of the hook mounting table 40 is in a substantially horizontal state, one end side 53 projects from the horizontal shaft 39 of the lifting base 20 so that the support arm 41 protrudes. It protrudes so as to face obliquely upward on the opposite side to the direction in which it is located.

  The reversing stopper 52 is formed by bending a rectangular plate into a U-shape and both ends are directed downward, and one end 56 of the both ends is attached to the collar 48 of the support arm 41. The surface 57 side having the other end is fixed to the upper portion of the mounting surface 24 of the base 23 so as to be disposed above the roller 54 of the reversing arm 51. A contact piece 58 is fixed to one end 56, and the roller 54 of the reversing arm 51 that rises following the support arm 41 by raising the elevating base 20 to the contact piece 58. Are in contact with each other. Since the reversing stopper 52 is formed in a U-shape and the opening portion of the U-shape is disposed downward, it is assumed that the vertically moving lift base 20 has moved up to the highest position. However, the collision between the reversing stopper 52 and the elevating base 20 can be avoided by entering the recessed portion of the U-shape.

  Then, when the elevator base 20 is moved up so that the hook mounting table 40 is moved further above the stop position in the upper heating chamber 2a, the roller 54 of the reversing arm 51 is brought into contact with the contact piece of the reversing stopper 52. After coming into contact with 58, the elevating base 20 is raised in a state in which further raising is prevented. For this reason, even if the elevating base 20 is further raised, the roller 54 of the reversing arm 51 maintains its height, and the position of the horizontal axis 39 of the elevating base 20 that is positioned lower than the position of the roller 54 is better. As the position becomes higher than the position of the roller 54, the support arm 41 side rotates in the ascending direction with the horizontal shaft 39 as a fulcrum. That is, the pot mounting table 40 fixed to the support arm 41 is moved up and inverted to move above the three-dimensional rice cooker body 6.

  Reference numeral 59 denotes an operation panel for performing control for heating the rice using the pot K in the three-dimensional rice cooker body 6 in the three-dimensional rice cooker 1 and controlling the movement of the pot lifting mechanism 7. In addition, in order to operate the shuttle raising / lowering mechanism 7 by pushing a movement button (not shown) on the operation panel 59, the open / close door 15 is in a fully closed state or a fully open state in which the opening 11 of the heating chamber 2 is closed. This can be done after the opening / closing sensor 17 detects this.

  Next, the operation and the like of the three-dimensional rice cooker 1 will be described with reference to the drawings.

  On the operation panel 59, the power is turned on to operate the three-dimensional rice cooker 1 and rice is cooked in each heating chamber 2 in the three-dimensional rice cooker body 6, so that each heating time and heating temperature can be set. Then, the operation of the shuttle lifting mechanism 7 is set.

  First, the operator operates while pressing a movement button (not shown) on the operation panel 59 so that the pot K easily mounts the pot mounting table 40 that is avoided above the three-dimensional rice cooker body 6. And is automatically stopped after being moved to a predetermined position in front of the opening 11 of the middle heating chamber 2b, which is also a position where the pot K can be carried in and out of the middle heating chamber 2b. . Then, the worker places the pot K containing rice and water once on the pot mounting surface 42 of the pot mounting table 40 stopped at a predetermined position in front of the opening 11 of the heating chamber 2b in the middle stage. .

  Next, the cooker K is charged to cook rice for the first time. For example, the upper heating chamber 2a into which the kettle K is loaded after the open / close door 15 of the upper heating chamber 2a is opened to open the opening 11. In order to move it toward the position, the operation button 59 is pressed and operated. Thereby, the pot mounting table 40 moves up and down to the vicinity of the front of the opening 11 of the upper heating chamber 2a in which the open / close door 15 is opened in order to cook rice with the pot K being mounted. Automatically stops the shuttle K at a position where it can be carried in and out.

  Next, since the operator carries the hook K into the upper heating chamber 2a, the guide plate 44 side of the pot K placed on the pot mounting surface 42 is slightly lifted, so that the bottom plate portion of the pot K 3 is supported only by the roller 45 on the hook mounting surface 42, and the hook K easily rolls into the heating chamber 2 and is conveyed toward the heating chamber 2. At this time, in the hook K on the hook mounting surface 42, the support piece 5 protruding from the side plate portion 4 is conveyed into the heating chamber 2 so as to face in the left-right direction.

  The shuttle K moving toward the upper heating chamber 2a has a support roller 13 at the edge 12 where the bottom plate portion 3 of the shuttle K is positioned below the opening 11 of the heating chamber 2 from above the shuttle mounting surface 42. The support piece 5 of the hook K is placed on the support rollers 14 on the wall surfaces 10 on both sides in the heating chamber 2 by being pushed further into the heating chamber 2, It is smoothly carried into the heating chamber 2. The hook K is placed above the gas burner 8 by the support piece 5 being supported by the support roller 14 and pushed into the heating chamber 2 and carried into a proper position in the upper heating chamber 2a. Thus, the opening / closing door 15 is turned to the closed state to close the opening 11 of the heating chamber 2.

  Next, in order to start rice cooking, an operation button (not shown) of the operation panel 59 is pressed to burn the gas in the gas burner 8 in the upper heating chamber 2a, whereby the pot K is heated.

  When rice is cooked in the heating chambers 2 at each stage as described above, first, the open / close door 15 of the heating chamber 2 into which the pot K is put is opened to the open state, and is placed at a predetermined position in front of the opening 11 of the middle heating chamber 2b. The hook mounting table 40 is moved up and down until it stops, and after the pot K is mounted on the pot mounting surface 42 of the pot mounting table 40, the open / close door 15 of the heating chamber 2 into which the pot K is charged is opened. After opening, the pot mounting table 40 is moved up and down to the vicinity of the front of the opening 11 of the heating chamber 2 and stopped at a position where the pot K can be loaded into the heating chamber 2, so that the pot K enters the heating chamber 2. When the door 15 is pushed in and finally the door 15 is closed, the carry-in is completed, the gas is burned, and each rice is cooked.

  Next, the pot K is carried out from the heating chamber 2 where the cooking of rice has been completed. First, after cooking, for example, by opening the opening / closing door 15 of the lower heating chamber 2c to the open state and opening the opening 11, the operation button 59 (not shown) of the operation panel 59 is continuously pressed and operated. In addition, the pot mounting table 40, which has been inverted above the three-dimensional rice cooker body 6 so as not to get in the way, is moved up and down to the vicinity of the front of the opening 11 of the lower heating chamber 2c where the rice cooking has been completed. The kettle K is automatically stopped from the heating chamber 2 at a position where it can be carried in and out.

  Next, the operator pulls out the pot K in the lower heating chamber 2c where the cooking of rice is finished, and is carried out toward the pot mounting table 40. When the hook K in which the support piece 5 is supported by the support roller 14 in the lower heating chamber 2 c is carried out of the heating chamber 2, the bottom plate portion 3 of the hook K is connected to the opening 11 of the heating chamber 2. It is carried out while being placed also on the support roller 13 of the edge portion 12 positioned below, and the support piece 5 is removed from the support of the support roller 14 and the bottom plate portion 3 is supported by the roller 45 on the shuttle mounting surface 42. The pot K is unloaded from the heating chamber 2 onto the pot mounting surface 42.

  Next, by continuing to operate a movement button (not shown) of the operation panel 59, the shuttle K is placed at a predetermined position in front of the opening 11 of the middle heating chamber 2b. It is automatically stopped after moving up and down as it is. This is the same position at which the operator can easily place the pot K after cooking the rice on the pot mounting surface 42 when cooking rice, even at a height that is easy to lift from the pot mounting surface 42. From a certain position, it is lifted by the worker and carried to the next process. Then, the pots K whose rice has been cooked by the respective heating chambers 2 are carried out of the heating chambers 2 to the pot mounting surface 42, and the pot mounting table 40 is moved to a predetermined position in front of the opening 11 of the middle heating chamber 2b. Will be moved up and down to the next process location.

  Thereafter, after all the rice cooking operations are completed, the operator can carry in and out the pot K from the upper heating chamber 2a by continuously operating the movement button (not shown) of the operation panel 59 and operating it. After moving up and down to the position, the reversing arm 51 and the reversing stopper 52 start to come into contact with each other by moving further up and down. Then, the pot mounting table 40 moves upward above the three-dimensional rice cooker body 6 and completely moves up to the top of the three-dimensional rice cooker body 6 to automatically stop and complete the rice cooking operation.

  According to this three-dimensional rice cooker 1, when the pot mounting table 40 is moved up and down in front of the three-dimensional rice cooker main body 6 and pivoted upward toward the apparatus main body, the operator moves on the operation panel 59. Although it is described that the button (not shown) is operated while being pressed, the movement button is not necessarily pressed and may be automatically moved to a predetermined position by pressing once. When the operating operator leaves the three-dimensional rice cooker body, it is possible to avoid an abnormality or an accident caused by the operation of the hook mounting table 40.

  In the above-described embodiment, the predetermined position where the operator temporarily stops the K for placing the hook K on the pot mounting table 40 is the same as the position where the hook K can be taken in and out of the middle heating chamber 2b. However, the stop position may be changed according to the body shape such as the height of the worker, and the height of the hook mounting table 40 that the worker temporarily stops to place the hook K is set to the middle level. In the case where the position is the same as the position at which the pot K can be carried in / out from the heating chamber 2b, the position sensor 50 that detects the position at which the pot K can be loaded / unloaded into / from the middle heating chamber 2b may also serve.

  In the above embodiment, the opening / closing door 15 of each heating chamber 2 is rotated in the horizontal direction in the upper heating chamber 2a, and is rotated in the vertical direction in the middle heating chamber 2b and the lower heating chamber 2c. However, the opening / closing door 15 may be rotated in any direction in the heating chamber as long as there is no hindrance to the operation of the shuttle raising / lowering mechanism 7 according to the purpose such as design and workability.

  In the above-described embodiment, the pot K is placed on the pot mounting surface 42 so that the pot K is loaded into and unloaded from all of the upper heating chamber 2a, the middle heating chamber 2b, and the lower heating chamber 2c. As an easy position, first, the pot K carried by the operator is placed on the pot mounting surface 42 stopped at a predetermined position in front of the opening 11 of the middle heating chamber 2b. However, in loading and unloading the pot K to and from the middle heating chamber 2b, the pot mounting table 40 is not moved to a predetermined position in front of the opening 11 of the middle heating chamber 2b. The hook K that has been conveyed by the operator may be directly carried in.

  Further, in the above-described embodiment, in the lifting drive unit 19 that is one of the configurations in which the shuttle K is moved up and down, the lot rod 25 that supports and guides the lifting base 20 to slide vertically is Although the two identically balanced structures have been described in the configuration, if the elevating base 20 can be smoothly slid without rattling, the lot rod 25 is replaced with one lot rod 25 or another simple rod. It is also possible to use a configuration that can be supported and guided.

  Furthermore, in the above-described embodiment, the heating using the gas burner 8 as the heating means 8 for carrying the cooker K into the heating chamber 2 and cooking rice has been described. For example, a heater or an electromagnetic coil using electricity is used. The structure which uses and heats may be sufficient.
