Moreover, the user interface 13 may further include a notification unit that notifies cooking guidance, setting details, warnings, and the like by voice.

The lid portion B may include a lid housing K (outer lid), an inner lid 22 , a handle 23 and a pressure switching valve 24 . The inner lid 22 is a lid that covers the opening of the inner pot C housed in the housing portion 10 . The inner lid 22 may be fixed to the lid housing K, or may be detachable. The handle 23 is a portion that a user grips to open and close the lid portion B. As shown in FIG. The pressure switching valve 24 is a valve for switching the pressure mode inside the inner pot C during cooking. In addition, a packing P is detachably attached to the inner lid 22 for sealing between the inner lid 22 and the inner pot C (the periphery of the opening thereof). A configuration for mounting the packing P will be described later. In the present embodiment, the main body housing L and the lid housing K are cylindrical and have a disk-like shape in plan view, but they are not limited to this. For example, the body housing L and the lid housing K may have a square prism shape.

The cooker 100 includes a locking mechanism D that locks the inner lid 22 and the accommodating portion 10 to close the lid portion B on the main body portion A. As shown in FIG. In the locking mechanism D, the lid portion B (inner lid 22) and the main body portion A (accommodating portion 10) are placed on top of each other, and the lid portion B and the main body portion A face each other in a direction parallel to the overlapping surface. When the inner lid 22 and the inner pot C are sealed by the packing P, the inner lid 22 and the housing portion 10 are engaged with each other. A specific example of the configuration of the locking mechanism D will be described below.

The housing portion 10 in the main body portion A has a flange 12 projecting outward from the outer circumference of the upper opening through which the inner pot C is put in and taken out. The accommodating portion 10 is held by the main body housing L with the flange 12 suspended from the upper end portion 11 of the main body housing L. As shown in FIG. On the other hand, a hook 25 (engagement portion) that engages the flange 12 is formed on the outer circumference of the inner lid 22 . The flange 12 is formed with notches 12a at equal angular intervals, which serve as passage portions for the hooks 25. As shown in FIG. The hooks 25 are formed at angular intervals corresponding to the notches 12a. FIG. 3 shows an exploded perspective view of the lid portion B as seen from below. Here, the inner lid 22 is joined to the lower surface of the lid housing K in advance. According to FIG. 3, it can be seen that the hooks 25 projecting inward from the inner circumference of the inner lid 22 are formed at equal angular intervals. The locking mechanism D can include the flange 12 and the notch 12a formed in the housing portion 10 and the hook 25 formed in the inner lid 22 as described above.

To close the lid portion B on the body portion A, first, the lid portion B (inner lid 22) is placed on the body portion A (accommodating portion 10) at a predetermined position where the hook 25 can pass through the notch 12a from top to bottom. to be placed. As a result, the lid portion B (inner lid 22) and the main body portion A (accommodating portion 10) are superimposed. A mark may be provided on each of the body portion A and the lid portion B so that the user can see at a glance the predetermined position where the hook 25 can pass through the notch 12a in the vertical direction. In this state, the user operates the handle 23 to rotate the lid portion B by a predetermined angle (for example, 15°) in a direction parallel to the overlapping surface with the main body portion A (hereinafter also referred to as a circumferential direction). Then, the flange 12 is fitted into the hook 25, and the closing operation between the body portion A and the lid portion B is thereby completed. FIG. 1 shows the state in which the lid portion B is thus closed. A stopper that restricts rotation beyond a predetermined angle may be provided so that the rotation can be completed at a position where the flange 12 and the hook 25 are reliably engaged.

As described above, the inner lid 22 is detachably attached with the packing P for sealing between the inner lid 22 and the inner pot C (the opening peripheral portion thereof). A configuration for mounting the packing P will be described with reference to FIGS. 3 and 4. FIG. 3 is an exploded perspective view of the lid portion B viewed from below, and the inner lid 22 is joined to the lower surface of the lid housing K here. The packing P is a ring-shaped lid packing along the inner peripheral shape of the inner lid 22 . The material of the packing P can be silicon rubber, fluororubber, chloroprene rubber, or the like. A packing holder H that holds the packing P includes a metal ring member 31 having a shape that matches the shape of the packing P, and joint members 30 are provided at three locations on the ring member 31, for example. The packing holder H is concentrically joined to the lower surface of the inner lid 22 by a joining member 30 . FIG. 4 shows a state in which the packing holder H is joined to the inner lid 22 by the joining member 30. As shown in FIG.

A groove 32 is formed in the inner peripheral portion of the packing P. As shown in FIG. The packing P is attached to the inner lid 22 by fitting the ring member 31 of the packing holder H into the groove 32 of the packing P along the circumference. In a state in which the inner pot C is housed in the housing portion 10 and the packing P is attached to the inner lid 22, the above-described closing operation of the lid portion B can be performed.

A user can easily attach and detach the packing P. The user can remove the packing P and clean the packing P alone. When cooking, the user attaches the packing P to the inner lid 22 and accommodates the inner pot C in the accommodation section 10 . Here, when cooking is started with the user forgetting to attach the packing P to the inner lid 22, the inner lid 22 and the inner pot C are not sealed, so the inside of the inner pot C must be pressurized. cannot cook properly. Even if the cooking is started as it is, the steam or moisture of the ingredients boiled in the inner pot C overflows from between the inner pot C and the inner lid 22.例文帳に追加In that case, there is a possibility that the overflowing water may enter the interior of the main body and cause the cooker 100 to malfunction. Also, if the user forgets to put the inner pot C in the housing portion 10, cooking cannot be done in the first place. If cooking is started as it is, electric power is supplied to the heating unit without the inner pot C, resulting in a so-called dry-heating state, which may cause the cooker 100 to malfunction.

In view of the above, it is necessary to reliably prevent cooking from being started while the packing P has been forgotten to be attached to the inner lid 22 or the inner pot C has been forgotten to be accommodated in the accommodation portion 10 .

Therefore, the cooker 100 according to the present embodiment is in at least one of the state in which the inner pot C is not accommodated in the accommodating portion 10 and the state in which the packing P is not attached to the inner lid 22 (first state). In addition, a blocking mechanism E is provided to prevent locking of the inner lid 22 and the housing portion 10 by the locking mechanism D by restricting the rotation of the lid portion B for closing the lid portion B (the inner lid 22). The blocking mechanism E will be described with reference to FIGS. 4 to 6. FIG.

FIG. 5 shows an enlarged view of the upper end portion 11 of the main body housing L on which the flange 12 of the receiving portion 10 is suspended. As shown in FIG. 5, the upper end portion 11 of the main body housing L is formed with a lock hole 52 that is recessed downward. The lock hole 52 is defined by a peripheral wall 52a extending in a direction intersecting the circumferential direction of the main body housing L. As shown in FIG. Lock hole 52 may be a step, groove, or recess defined by peripheral wall 52a.

FIG. 4 shows the lid portion B in which the packing holder H is joined to the inner lid 22 . However, the packing P is removed here. 4, a lock pin hole 60 is formed in the lower end portion of the lid housing K (the portion overlapping the upper end portion 11 of the main body housing L when the lid portion B is closed). Blocking mechanism E may include a locking pin 61 movable through this locking pin hole 60 . The blocking mechanism E has a drive mechanism F that moves the lock pin 61 . In at least one of the state in which the inner pot C is not accommodated in the accommodating portion 10 and the state in which the packing P is not attached to the inner lid 22 (the first state), the drive mechanism F moves the tip of the lock pin 61. Rotational movement of the lid portion B is restricted by moving the lock pin 61 so that the portion is engaged with the lock hole 52 . In addition, in the state (second state) in which the inner pot C is housed in the housing portion 10 and the packing P is attached to the inner lid 22, the drive mechanism F is configured so that the tip portion of the lock pin 61 extends from the lock hole 52. By moving the lock pin 61 away, the restriction on the rotational movement of the lid portion B is released. Details of the drive mechanism F will be described later with reference to FIG.

In a state where the packing P is removed as shown in FIG. In this state, in order to close the lid portion B on the main body portion A, when the lid portion B is placed on the main body portion A at a predetermined position where the hook 25 can pass through the notch 12a from the top to the bottom, the lock pin 61 is locked. The tip portion enters into the lock hole 52 formed in the upper end portion 11 of the main body housing L. As shown in FIG. Therefore, even if the user tries to rotate the lid portion B in a direction parallel to the overlapping surface with the main body portion A, the lock pin 61 abuts against the peripheral wall 52a of the lock hole 52 and cannot be rotated.

On the other hand, when the packing P is attached to the inner lid 22 by the packing holder H and the inner pot 3 is housed in the housing portion 10, the drive mechanism F works to move the tip of the lock pin 61 away from the lock hole 52. , and the lock pin 61 is retracted into the lid housing K through the lock pin hole 60 . As a result, the restriction on the rotation of the lid portion B in the direction parallel to the overlapping surface with the main body portion A is released, and the closing operation of the lid portion B becomes possible.

FIG. 6 shows a detailed configuration example of the drive mechanism F. As shown in FIG. 6, a lock pin 61 is disposed within the lid housing K and is movable through a lock pin hole 60 formed in the lower end of the lid housing K. As shown in FIG. Further, as shown in FIG. 4, a pin hole 40 is formed in a portion of the inner lid 22 that can overlap the packing P attached to the inner lid 22 in plan view. The drive mechanism F may further include an abutment pin 62 that is movable through the pin hole 40 and abuts on the packing P attached to the inner lid 22 . When the packing P is not attached as shown in FIG. 4, the contact pin 62 protrudes from the pin hole 40 .

As shown in FIG. 6 , the drive mechanism F further has a connecting member 63 that connects the contact pin 62 and the lock pin 61 . The connecting member 63 interlocks the contact pin 62 and the lock pin 61 . The drive mechanism F further includes a coil spring S that is a biasing member that biases the lock pin 61 in the direction of protruding from the lock pin hole 60 . A rod 66 is provided on an upper portion of an inner wall 64 of the lid housing K and is connected to the lower surface of the top plate of the lid housing K through a loose fit hole (not shown) formed in the connecting member 63. A coil spring is provided. S is arranged so as to surround this rod 66 . The rod 66 functions as a guide member that guides movement of the connecting member 63 in a direction parallel to the axis of the lock pin 61 . Further, inside the lid housing K, a restricting member 67 that restricts lateral movement of the lock pin 61 may be provided.

FIG. 6(a) shows a state (second state) in which the inner pot C is housed in the housing portion 10 and the packing P is attached to the inner lid 22, and a hook for closing the lid portion B is attached to the body portion A. FIG. 25 shows a state in which the lid portion B is placed on the main body portion A at a predetermined position where the notch 12a can be passed from top to bottom. In this case, the packing P pushed up by the inner pot C comes into contact with the contact pin 62 , and the contact pin 62 is pushed up against the biasing force of the coil spring S. The lock pin 61 interlocks with the contact pin 62 via the connecting member 63 , and the tip of the lock pin 61 leaves the lock hole 52 . This is the state in which the regulation of rotation in the direction parallel to the overlapping surface of the lid portion B with the main body portion A is released, and the closing operation of the lid portion B is possible.

FIG. 6B shows a state in which the packing P is attached to the inner lid 22 but the inner pot C is not accommodated in the accommodating portion 10, and the hook 25 is notched to close the lid portion B to the main body portion A. It shows a state in which the lid portion B is placed on the main body portion A at a predetermined position that allows passage of the lid portion 12a from top to bottom. In this case, since there is no inner pot C, the packing P cannot push up the contact pin 62 , and the tip of the lock pin 61 remains engaged with the lock hole 52 by the biasing force of the coil spring S. This is a state in which the rotation of the lid portion B in the direction parallel to the overlapping surface with the main body portion A is restricted, and the closing operation of the lid portion B is prevented. As described above, when the packing P is attached to the inner lid 22, the contact pin 62 contacts the packing P. However, unless the inner pot C is accommodated in the accommodation portion 10, the lock pin 61 is not in contact with the coil spring S. The tip of the lock pin 61 does not move away from the lock hole 52 against the urging force of .

FIG. 6(c) shows a state in which the packing P is not attached to the inner lid 22, and the hook 25 is placed at a predetermined position where the hook 25 can pass through the notch 12a from top to bottom in order to close the lid portion B of the main body A. A state in which the cover portion B is placed on the portion A is shown. In this case, since the packing P is not attached to the inner lid 22 , the inner pot C does not reach the contact pin 62 even if the inner pot C is housed in the housing portion 10 . Therefore, the contact pin 62 is not pushed up, and the tip of the lock pin 61 remains engaged with the lock hole 52 by the biasing force of the coil spring S. Therefore, in this state, the rotation of the lid portion B in the direction parallel to the overlapping surface with the main body portion A is restricted, and the closing operation of the lid portion B is prevented.
