JP 2011-92493 A

  However, in the device of Patent Document 1, the pot mounting table is provided separately from the three-dimensional rice cooker. Since the pot mounting table protrudes to the front of the three-dimensional rice cooker, it disturbs the operator. Therefore, there is a problem that workability is poor because it is necessary to store the pot mounting table above the three-dimensional rice cooker so as not to disturb when not in use.

  This invention is completed based on the above situations, Comprising: It aims at providing the cooking appliance which is equipped with the raising / lowering function of a cooking container, and is excellent in workability | operativity.

  The present invention is a cooking apparatus main body having a cooking chamber, an opening / closing door that opens and closes the cooking chamber, and an opening / closing door whose rear surface is a mounting surface of the cooking container, and the cooking container on the rear surface of the door. By raising and lowering the open / close door from the placed state, an elevating device that elevates and lowers the cooking container between a height position corresponding to the cooking chamber and a height position for performing a delivery operation is provided. The “delivery operation” means an operation of delivering (replacement) the cooking container to / from a transport means such as a work cart.

  The cooking apparatus of the present invention uses an opening / closing door for the lifting platform of the cooking container. If it is an open / close door, it will not interfere with the operator if it is closed when not in use. Therefore, unlike the conventional type in which the mounting table is provided separately from the three-dimensional rice cooker, it is not necessary to perform the work of storing the pot mounting table above the three-dimensional rice cooker after using the lift. Good.

The following configuration is preferable as an embodiment of the present invention.
The elevating device includes an elevating link that elevates and lowers the opening / closing door by a rotation operation around the rotation axis, and a drive unit that rotates the elevating link around the rotation axis. In this configuration, the door is lifted and lowered using the lifting link. If it is a lifting link type lifting device, the structure is relatively simple and the durability is good.

A weight that balances the weight of the elevating link so that a support end that supports the open / close door faces the cooking chamber side, and the open / close door is positioned at a height position corresponding to the cooking chamber, A rotation stopper for stopping rotation of the elevating link at a stop position. In this configuration, the open / close door can be positioned by a mechanical structure (rotary stopper, weight).

The movable part that moves up and down with respect to the initial position by rotating a part of the elevating link upward or downward, thereby rotating the elevating link around the rotation axis. And a moving mechanism for moving the movable body up and down, and when the movable body is separated from the lift link at the initial position, the drive unit is separated from the lift link that is stopped by the rotation stopper. It is a structure. In this configuration, the movable body is separated from the lifting link at the initial position. Therefore, even if the movable body deviates from the initial position and stops, the influence does not reach the lifting link and the opening / closing door.

The cooking chamber has an upper cooking chamber that is higher than a height position where the cooking container is transferred, and a lower cooking chamber that is lower than the height position where the cooking container is transferred. The opening / closing door includes an upper opening / closing door that opens / closes the upper cooking chamber, and a lower opening / closing door that opens / closes the lower cooking chamber, and the lifting device includes the upper opening / closing door. An upper stage lifting device having an upper stage lifting link for raising and lowering the opening and closing door, and a lower stage lifting device having a lower stage lifting link for raising and lowering the lower stage opening and closing door, the upper stage lifting link and the lower stage lifting link are The movable body is positioned above and below, and an initial position of the movable body is set to an intermediate position between the two lifting links. As the movable body moves upward with respect to the initial position, the movable body moves to the upper stage side. Press a part of the lift link By raising, the upper stage lifting link rotates to lower the upper stage opening / closing door from the upper stage position corresponding to the upper stage cooking chamber, and with the downward movement of the movable body based on the initial position Te, by the movable member pushes down a portion of the lower stage side elevation link rotates said lower side lifting link, raises the lower side door from the lower position corresponding to the lower side cooking chamber arrangement It is. In this configuration, the drive unit (movable body or moving mechanism) is shared by the two lifting links. Therefore, compared with the case where a dedicated drive unit is provided for each of the lift links, the number of parts is small and there is a cost merit.

  According to the present invention, the burden on the operator can be reduced.

Each open / close door 33 is configured to open downward by pulling a handle 38 provided on the upper part of the door in the downward direction toward the front, and a rice cooker (the “cooking container” of the present invention) with respect to each heating chamber 31a to 31c. This corresponds to a configuration in which 200 is taken in and out from the front side. In each drawing, some handles 38 are omitted as necessary. The upper heating chamber 31a corresponds to the “upper cooking chamber” of the present invention, and the lower heating chamber 31c corresponds to the “lower cooking chamber” of the present invention. The opening / closing door 33a for opening / closing the upper heating chamber 31a corresponds to the “upper door” of the present invention, and the opening / closing door 33c for opening / closing the lower heating chamber 31c corresponds to the “lower opening door” of the present invention. To do.

  The three-dimensional rice cooker 20 includes a first lifter (corresponding to the “upper stage lifting apparatus” of the present invention) 50a and a second lifter (corresponding to the “lower stage lifting apparatus” of the present invention) 50c. The first lifter 50a is a lifter that uses the open / close door 33a that opens and closes the upper heating chamber 31a as a lifting platform for moving the rice cooker 200 up and down. By raising and lowering the rice cooker 200, the upper stage position (see FIGS. 11 and 21) corresponding to the upper heating chamber 31a and the middle stage position (see FIGS. 10 and 20) corresponding to the middle heating chamber 31b. Go up and down between.

  The second lifter 50c is a lifter that uses the open / close door 33c that opens and closes the lower heating chamber 31c as a lifting platform for raising and lowering the rice cooker 200. The second lifter 50c opens and closes from the state where the rice cooker 200 is placed on the back surface 34. By raising and lowering the door 33c, the rice cooker 200 is moved to a lower position corresponding to the lower heating chamber 31c (see FIGS. 16 and 27) and an intermediate position corresponding to the middle heating chamber 31b (refer to FIGS. 15 and 26). ).

  Note that, in the middle position (corresponding to the “height position for performing the delivery work” of the present invention), as shown in FIGS. It becomes the height substantially the same as the base plate 220 of this, and it becomes possible to perform the delivery operation | work which replaces the rice cooking pot 200 between both. Further, the upper position and the lower position correspond to the “height position corresponding to the cooking chamber” of the present invention.

The first lifter 50 a includes a support member 60, an elevating link (corresponding to the “upper side elevating link” of the present invention) 51 a, a driven link 53 a, and a drive unit 70.
Specifically, as shown in FIG. 2, support frames 45 are attached to the left and right sides of the rice cooker body 30. In FIG. 2, only the support frame 45 attached to the front side of the rice cooker body 30 is shown, but the support frame 45 is attached to the back side as well as the front side.

  The elevating link 51a and the driven link 53a form a pair and are attached to the inner wall of the left and right support frames 45 as a pair. As shown in FIG. 2, the elevating link 51a and the driven link 53a are arranged vertically, the elevating link 51a rotates about the rotation axis H1a, and the driven link 53a rotates about the rotation axis H3a. As shown in FIG. 2, the link tips of the elevating link 51 a and the follower link 53 a protrude forward from the front wall of the rice cooker body 30, and are fixed to the mounting walls 63 provided on both sides of the support member 60. Has been.

  The support member 60 has a long shape in the width direction (X direction) of the three-dimensional rice cooker 20. The support member 60 rotatably supports the opening / closing door 33a via a hinge shaft 65. The open / close door 33a can be rotated about 90 ° about the hinge shaft 65, and can be displaced between an upright position and a horizontal position as shown in FIG. And the back surface 34 of the door 33a is a flat mounting surface, and the rice cooker 200 can be mounted on the back surface 34 when the door 33a is opened and tilted to the horizontal position. The support member 60 is provided with a stopper (not shown) that stops the opening / closing door 33a from rotating in the horizontal position, and the horizontal position is maintained even when the rice cooker 200 is placed on the back surface 34. ing.

  The elevating link 51a, the driven link 53a, the mounting wall 63, and the support frame 45 constitute a four-joint parallel link. When the elevating link 51a is rotated around the rotation axis H1a, the support member 60 maintains its posture. The door 33a is lifted and lowered to move up and down between the upper position shown in FIG. 18 and the middle position shown in FIG.

  The open / close door 33a corresponds to the upper heating chamber 31a, and the neural position is the upper position shown in FIG. The first lifter 50a is configured to position the open / close door 33a at the upper position, which is a neural position, by a mechanical positioning structure.

  Specifically, the elevating link 51a is heavier on the tip side to which the opening / closing door 33a is attached and rotates (tilts) so that the tip faces downward in a free state. Therefore, in the first lifter 50a, a weight W that balances the weight of the lift link 51a is provided so that the lift link 51a faces the tip.

  The attachment structure of the weight W will be described. As shown in FIGS. 5 and 9, the rear end plate 55 is attached to the left and right elevating links 51a by connecting the rear ends. A pair of weights W are attached to the rear end plate 55 on the left and right sides. Since the weight W is set so that the rear part of the link becomes heavy, the elevating link 51a is balanced in a posture in which the tip is directed upward.

  And the supporting member 60 also serves as a rotation stopper of the lifting link 51a, and when the lifting link 51a rotates to the rising position shown in FIG. 18, the supporting member 60 hits the front wall of the rice cooker body 30. The lift link 51a is not further rotated. In other words, the opening and closing door 33a is positioned at the upper position, which is the neutral position, by the support member 60 abutting against the front wall and restricting the rotation of the lift link 51a.

  Note that, according to the present invention, a weight for balancing the weight of the elevating link so that the support end supporting the open / close door faces the cooking chamber, and the height of the open / close door corresponding to the cooking chamber. It is configured to include a rotation stopper (in the embodiment, a support member 60) that stops the elevating link from being rotated at a stop position (in the up position in the embodiment) so as to be positioned at a position.

  As shown in FIGS. 6 and 9, an intermediate plate 56 is attached to the elevating link 51a. 5 and 6 are views of the three-dimensional rice cooker as viewed from the front side, but the intermediate plate 56 is omitted in FIG. 5 for easy understanding of the arrangement structure of the weight W and the arrangement of the intermediate plate 56. In FIG. 6, the rear end plate 55 and the weight W are omitted.

  The intermediate plate 56 is located on the front side of the rear end plate 55 (the rear side of the rotation shaft H1a) and, like the rear end plate 55, connects the left and right lifting links 51a. In addition, rollers 58 a are attached to the middle plate 56 at two locations near the center in the width direction via brackets 57. The roller 58a is a counterpart of the movable plate 71 of the drive unit 70 described below.

  The drive unit 70 functions to rotate the elevating link 51a about the rotation axis H1a, and as shown in FIGS. 3 and 7, a movable plate (corresponding to the “movable body” of the present invention) 71 and A moving mechanism 73 for moving the movable plate 71 in the vertical direction and a motor 77 are provided. The moving mechanism 73 includes a ball screw shaft 74 and a ball nut 75. The movable plate 71 is attached to a ball nut 75. When the ball screw shaft 74 is rotated by the power of the motor 77, the ball nut 75 moves in the vertical direction along the ball screw shaft 74. The plate 71 is moved up and down.

  The moving mechanism 73, the movable plate 71, and the motor 77 which comprise the drive part 70 are arrange | positioned at the center rear part side of the rice cooker main body 30, as shown in FIG. 5, FIG. And in the initial position shown in FIG. 7, the movable plate 71 is located under the roller 58a of the raising / lowering link 51a. Therefore, when the driving unit 70 is driven to raise the movable plate 71 from the initial position, the movable plate 71 pushes the rear side of the elevating link 51a upward through the roller 58a. As a result, the elevating link 51a rotates about the rotation axis H1a (rotates in a direction to lower the tip), and the driven link 53a rotates about the rotation axis H3a. The position is displaced from the position to the middle position shown in FIG.

  The basic structure of the second lifter 50c is the same as that of the first lifter 50a, and the opening / closing door 33c is moved to the lower position shown in FIG. 24 and the middle position shown in FIG. Is to be displaced between. Specifically, as shown in FIGS. 2 and 3, the second lifter 50 c is similar to the first lifter 50 a, and includes a lift link (corresponding to the “lower lift link” of the present invention) 51 c and a driven link. 53c. Like the link on the first lifter 50a side, the lift link 51c and the driven link 53c are attached to the inner wall of the support frame 45. The lift link 51c rotates about the rotation axis H1c, and the driven link 53c rotates. It rotates about the axis H3c. The links 51c and 53c on the second lifter 50c side are on the bottom, and the links 51a and 53c on the first lifter 50a side are on the top.

  As shown in FIGS. 2 and 3, the link tips of the lift link 51 c and the follower link 53 c protrude forward from the front wall of the rice cooker body 30, with respect to the mounting walls 63 provided on both sides of the support member 60. The shaft is fixed.

  The elevating link 51c, the follower link 53c, the mounting wall 63, and the support frame 45 constitute a four-joint parallel link. When the elevating link 51c is rotated about the rotation axis H1c, the support member 60 maintains its posture. The door 33c is moved up and down to displace between the lower position shown in FIG. 24 and the middle position shown in FIG. The open / close door 33c can be rotated about 90 ° about the hinge shaft 65 in the same manner as the open / close door 33c, and can be displaced between an upright position and a horizontal position as shown in FIG. . The back surface 34 of the open / close door 33a is a flat mounting surface. When the open / close door 33a is opened and tilted to the horizontal position, the rice cooker 200 can be mounted on the back surface 34.

  The open / close door 33c corresponds to the lower heating chamber 31c, and the neural position is the lower position shown in FIG. The second lifter 50c is configured to position the open / close door 33c at the lower position, which is a neural position, by a mechanical positioning structure.

  Specifically, the elevating link 51c is heavier on the distal end side to which the opening / closing door 33c is attached and rotates (tilts) so that the distal end faces downward in a free state. And, like the first lifter 50a side, the support member 60 also serves as a rotation stopper for the elevating link 51c. When the elevating link 51c rotates to the lowered position shown in FIG. The elevating link 51c is configured not to rotate any further. In other words, the opening and closing door 33c is positioned at the lower position, which is the neutral position, by the support member 60 abutting against the front wall and restricting the rotation of the lift link 51c.

  Similarly to the lift link 51a on the first lifter 50a side, an intermediate plate 56 is attached to the lift link 51c on the second lifter 50c side so as to connect the left and right lift links 51c. Rollers 58c are attached to the middle plate 56 at two locations near the center in the width direction via brackets 57t.

  As shown in FIG. 7, the roller 58c on the second lifter 50c side is positioned below the movable plate 71 that stops at the initial position. Therefore, when the driving unit 70 is driven to lower the movable plate 71 from the initial position, the movable plate 71 pushes the rear side of the elevating link 51c downward through the roller 58c. As a result, the elevating link 51c rotates about the rotation axis H1c (rotates in the direction in which the tip is raised), and the driven link 53c rotates about the rotation axis H3c. The position is displaced from the position to the middle position shown in FIG.

  That is, in the three-dimensional rice cooker 20, the first lifter 50a and the second lifter 50c share the drive unit 70 by setting the initial position of the movable plate 71 to an intermediate position between the two lifting links 51a and 51c. When the movable plate 71 is raised from the initial position, the first lifter 50a is operated, and the open / close door 33a can be lowered from the upper position, which is the neutral position, to the middle position. Further, when the movable plate 71 is lowered from the initial position, the second lifter 50c is operated, and the open / close door 33c can be raised from the lower position which is the neutral position to the middle position.

Moreover, in this embodiment, since the doors 33a and 33c are neutrally positioned using a mechanical structure, there are the following advantages.
As a method of positioning the open / close door 33a and the open / close door 33c at the neutral position, there is a method of using the drive unit 70 in addition to a method of using a mechanical structure. That is, by using the movable plate 71 of the drive unit 70 to regulate the positions of the elevating link 51a and the elevating link 51c, the open / close door 33a is lowered to the upper position, and the open / close door 33c is lowered to the neutral position. There is a method to restrict the position. However, when positioning using the movable plate 71, if there is an error in the stop position of the movable plate 71, the stop positions of the open / close doors 33a and 33c will deviate from the neutral position.

  Therefore, in order to accurately stop the open / close doors 33a and 33c at the neutral position, it is necessary to control the stop position of the movable plate 71 with high accuracy. In this regard, in the present embodiment, as described above, the opening / closing doors 33a and 33c are positioned at the neutral position by using a mechanical structure, so that there is a merit that the control of the driving unit 70 can be made relatively rough. .

  Further, as shown in FIG. 7, the initial position of the movable plate 71 is set to have a gap between the roller 58a on the first lifter 50a side and the roller 58c on the second lifter 50c side. . That is, when the movable plate 71 is separated from the rollers 58a and 58c of the lift links 51a and 51c at the initial position, the drive unit 70 is separated from the lift links 51a and 51c that are rotationally stopped. .

  With this structure, even if the initial position of the movable plate 71 varies somewhat, the movable plate 71 does not interfere with the rollers 58a and 58c of the lifters 50a and 50c, and the stop positions of the open / close doors 33a and 33c. Will not be affected. That is, the open / close doors 33a and 33c are structured not to be displaced from the neutral position.

2. An operation procedure when cooking (rice cooking) using the upper heating chamber 31a will be described.
(A) Work procedure for moving rice cooker 200 on work cart 210 to upper heating chamber 31a In the state before work, as shown in FIG. 3, open / close door 33a is in the upper position, open / close door 33b is in the middle position, It is assumed that the open / close door 33c is in the lower position and the corresponding heating chambers 31a, 31b, 31c are closed. Further, the lift link 51a on the first lift 50a side is in the raised position, and the lift link 51c on the second lift 50c side is in the lowered position. The movable plate 71 of the drive unit 70 is in the initial position shown in FIGS. 3 and 7, and between the roller 58a on the first lift 50a side and the roller 58c on the second lift 50c side, There is also a gap.

  In order to move the rice cooker (rice cooker containing the washed rice) 200 from the work carriage 210 to the upper heating chamber 31a, first, the door 33a at the upper position is opened by hand, and the door is opened. 33a is displaced from the upright position to the horizontal position (see FIGS. 8 and 18). Thereafter, the driving unit 70 is operated by operating the operation panel P provided on the front wall.

  By the operation of the drive unit 70, the movable plate 71 rises from the initial position. Then, the rising movable plate 71 pushes up the roller 58a of the lift link 51a from below. Therefore, since the elevating link 51a rotates about the rotation axis H1a in the R direction shown in FIG. 19, the open / close door 33a is lowered. When the open / close door 33a is lowered to the middle position (see FIGS. 9 and 19), after the drive unit 70 is temporarily stopped, the work of replacing the rice cooker 200 from the work carriage 210 to the open / close door 33a is performed (FIG. 10, FIG. 10). FIG. 20).

  Thereafter, the drive unit 70 is operated again, and this time the movable plate 71 is lowered. Then, the elevating link 51a is rotated about the rotation axis H1a in the R direction shown in FIG. 21 by the action of the weight W. Therefore, the open / close door 33a rises. When the opening / closing door 33a moves to the upper position shown in FIGS. 11 and 21, the support member 60 abuts against the front wall of the rice cooker body 30, whereby the rotation of the lifting link 51a is restricted, and the opening / closing door 33a is Positioned at position. And after rotation restraint of the raising / lowering link 51a, when the movable plate 71 moves to the initial position, the drive part 70 is stopped.

  As shown in FIGS. 11 and 21, in a state where the open / close door 33a is moved to the upper position, the rice cooking pot 200 on the open / close door 33a faces the entrance of the upper heating chamber 31a. Therefore, by pressing the side surface, the rice cooker 200 is pushed into the heating chamber 31a as shown in FIGS. Thereafter, the open / close door 33a is closed (see FIG. 23).

  By the above, since the rice cooker 200 will be in the heating chamber 31a of the three-dimensional rice cooker 20, after that, the three-dimensional rice cooker 20 will be operated and rice cooking will be started. That is, the heat treatment is started in the heating chamber 31a. Thereby, the rice cooker 200 is heated, and rice is cooked in the rice cooker 200.

(B) Work procedure for transferring cooked rice cooker 200 from upper heating chamber 31a to work cart 210 First, the handle 38 is grasped, and the open / close door 33a of the heating chamber 31a is opened and displaced to the horizontal position. Thereafter, the rice cooker 200 is manually pulled out of the heating chamber 31a and moved onto the open / close door 33a. Next, the drive unit 70 is operated by operating the operation panel P provided on the front wall.

  By the operation of the drive unit 70, the movable plate 71 rises from the initial position. Then, the rising movable plate 71 pushes up the roller 58a of the lift link 51a from below. Therefore, since the elevating link 51a rotates about the rotation axis H1a in the R direction shown in FIG. 19, the open / close door 33a is lowered. When the open / close door 33a is lowered to the middle position, the drive unit 70 is stopped. Thereafter, the rice cooker 200 on the open / close door 33a is moved to the work cart 210 side by pushing the side surface, so that the cooked rice cooker 200 having been cooked can be transferred onto the operation cart 210.

3. The work procedure at the time of cooking (cooking rice) using the lower heating chamber will be described.
(A) Work procedure for moving rice cooker 200 on work cart 210 to lower heating chamber In the state before work, as shown in FIG. 3, open / close door 33a is in the upper position, open / close door 33b is in the middle position, and is opened / closed. It is assumed that the door 33c is in the lower position and the corresponding heating chambers 31a, 31b, 31c are closed. Further, the lift link 51a on the first lift 50a side is in the raised position, and the lift link 51c on the second lift 50c side is in the lowered position. The movable plate 71 of the drive unit 70 is in the initial position shown in FIGS. 3 and 7, and between the roller 58a on the first lift 50a side and the roller 58c on the second lift 50c side, There is also a gap.

  In order to move the rice cooker (rice cooker containing the washed rice) 200 from the work cart 210 to the lower heating chamber 31c, first, the door 33c at the lower position is opened by hand, and the door is opened. 33c is displaced from the upright position to the horizontal position (see FIGS. 13 and 24). Thereafter, the driving unit 70 is operated by operating the operation panel P provided on the front wall.

  The movable plate 71 is lowered from the initial position by the operation of the driving unit 70. Then, the lowering movable plate 71 pushes down the roller 58c of the elevating link 51c from above. Therefore, since the elevating link 51c rotates about the rotation axis H1c in the R direction shown in FIG. 25, the open / close door 33c rises. Then, when the open / close door 33c is raised to the middle position (see FIGS. 14 and 25), after the drive unit 70 is temporarily stopped, the work of replacing the rice cooker 200 from the work carriage 210 to the open / close door 33c is performed (FIG. 15, (See FIG. 26).

  Then, the drive part 70 is operated again and this time the movable plate 71 is raised. Then, the elevating link 51c rotates about the rotation axis H1c in the S direction shown in FIG. Therefore, the open / close door 33c is lowered. When the opening / closing door 33c moves to the lower position in FIGS. 16 and 27, the support member 60 abuts against the front wall of the rice cooker body 30, whereby the rotation of the lifting link 51c is restricted, and the opening / closing door 33c is moved to the lower position. Positioned. And after the rotation restraint of the raising / lowering link 51c, when the movable plate 71 moves to the initial position, the drive part 70 is stopped.

  As shown in FIGS. 16 and 27, when the open / close door 33c is moved to the lower position, the rice cooker 200 on the open / close door 33c faces the inlet of the lower heating chamber 31c. Therefore, by pressing the side surface, the rice cooker 200 is pushed into the heating chamber 31c as shown in FIGS. Thereafter, the open / close door 33 is closed (see FIG. 29).

  By the above, since the rice cooker 200 will be in the heating chamber 31c of the three-dimensional rice cooker 20, after that, the three-dimensional rice cooker 20 will be operated and rice cooking will be started. That is, the heat treatment is started in the heating chamber 31c. Thereby, the rice cooker 200 is heated and rice is cooked.

(B) Work procedure from rice cooking to taking out First, the handle 38 is grasped, the opening / closing door 33c is opened, and it is displaced to a horizontal position. Thereafter, the rice cooker 200 is pulled out from the heating chamber 31c by hand and moved onto the open / close door 33c. Next, the drive unit 70 is operated by operating the operation panel P provided on the front wall.

  The movable plate 71 is lowered from the initial position by the operation of the driving unit 70. Then, the rising movable plate 71 pushes up the roller 58c of the elevating link 51c from below. Therefore, since the elevating link 51c rotates about the rotation axis H1c in the R direction shown in FIG. 25, the open / close door 33c rises. And if the opening-and-closing door 33c raises to a middle position, the drive part 70 will be stopped. Thereafter, the rice cooker 200 on the open / close door 33c is moved to the work cart 210 side by pushing the side surface, so that the cooked rice cooker 200 having been cooked can be transferred onto the operation cart 210.

  In the above description, the case where rice cooking is performed using the upper heating chamber 31a and the case where rice cooking is performed using the lower heating chamber 31c are described separately. However, the heating chambers 31a to 31c in each stage are simultaneously performed. You can also use it to cook rice.

4). Description of Effects The three-dimensional rice cooker 20 disclosed in the present embodiment includes a first lift 50a and a second lift 50c that raise and lower the rice cooker 200. Therefore, an operator's burden is reduced about the work which moves rice cooker 200 from work cart 210 to upper and lower heating chambers 31a and 31c, and the work which moves rice cooker 200 from upper and lower heating chambers 31a and 31c to work cart 210. I can do it.

  In addition, the 1st lift 50a and the 2nd lift 50c have a structure which raises / lowers the rice cooker 200 using the opening-and-closing doors 33a and 33c. If it is the opening and closing door 33, it is not in the way of the operator if it is closed and returned to the upright position when not in use. Therefore, unlike the conventional type in which the mounting table is provided separately from the three-dimensional rice cooker, it is not necessary to perform the work of storing the pot mounting table above the three-dimensional rice cooker after using the lift. Good.

  Moreover, in the three-dimensional rice cooker 20 disclosed in this embodiment, since the drive unit 70 is commonly used by the first lift 50a and the second lift 50c, the drive unit 70 is dedicated for each lift 50a, 50c. Compared with the case of providing, it is possible to reduce the number of parts, and the cost merit is high. There is also an advantage that the apparatus can be miniaturized.

  Moreover, in the three-dimensional rice cooker 20 disclosed in this embodiment, since the raising / lowering links 51a and 51c are made into the both-ends structure, it is possible to raise / lower the rice cooking pot 200 stably. Moreover, in the three-dimensional rice cooker 20 disclosed in this embodiment, since the weight W is arrange | positioned using the dead space made in the right-and-left both sides of the drive part 70, an apparatus can be reduced in size.
