In addition, the following embodiments are not intended to limit the scope of the invention, and combinations of features described in the embodiments are not necessarily essential to the invention. Two or more of the plurality of features described in the embodiments may be combined arbitrarily. In addition, the same reference numerals are assigned to the same or similar configurations, and overlapping descriptions are omitted.

FIG. 1 is a perspective view showing the appearance of a cooker 100 according to the embodiment, and FIG. 2 is an exploded perspective view of the cooker 100 . The cooking utensil 100 can be heating cooking utensils such as an electric pressure cooker and a rice cooker. The cooker 100 includes: a main body A, which controls the heating of the inner pot C according to a predetermined heating program; and a cover B, which is detachable from the upper part of the main body A.

The main body A can include a housing portion 10 for housing the inner pot C, a main body shell L, and a human-computer interaction interface 13 . The housing portion 10 is also called an outer pot, and is formed of metal or the like in order to transfer heat to the inner pot C. As shown in FIG. A heating unit (heater), not shown, which heats the inner pot C via the housing portion 10 is disposed below the housing portion 10 . The heating unit can include an induction heating coil for inductively heating the inner pot C housed in the storage unit 10 . Moreover, the main-body part A can also be provided with the control part which controls a heating part. Preferably, the receiving portion 10 is fixed to the main body casing L. As shown in FIG. The man-machine interface 13 can include: an operation part such as a button or a knob, which is used for setting related to cooking; and a display part, which displays the setting content and a clock. In addition, the man-machine interface 13 may further include a notification unit for reporting cooking instructions, setting contents, warnings, etc. by sound.

The cap portion B can include a cap case K (outer cap), an inner cap 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 accommodated in the housing portion 10 . The inner cover 22 is preferably fixed to the cover case K, but may be detachably configured. The handle 23 is a portion that is held by the user to open and close the lid B. As shown in FIG. The pressure switching valve 24 is a valve for switching the pressure mode in the inner pot C during cooking. In addition, the inner lid 22 is detachably attached with a packing P for sealing between the inner lid 22 and (the opening peripheral portion of the inner pot C). The structure for mounting of the pad P is discussed later. In the present embodiment, the main body case L and the cover case K have a cylindrical shape and a disc-shaped form in plan view, but are not limited thereto. For example, the main body case L and the cover case K may have a quadrangular column shape.

Cooker 100 includes locking mechanism D for locking inner lid 22 and accommodating portion 10 in order to close lid portion B with respect to main body portion A. As shown in FIG. The locking mechanism D relatively rotates the cover B and the main body A in a direction parallel to the overlapping surface in a state where the cover B (inner cover 22 ) and the main body A (receptacle 10 ) are overlapped, so that the inner cover The inner lid 22 and the accommodating part 10 are locked in a state where the gasket P seals between the inner pot C and the inner lid 22 . A specific example of the structure of the locking mechanism D will be described below.

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

In order to close the lid B with respect to the main body A, first, place the lid B (inner lid 22 ) on the main body A (accommodating portion 10 ) at a predetermined position where the hook 25 can pass through the notch 12a from top to bottom. above. Thereby, the cover part B (inner cover 22) and the main-body part A (accommodating part 10) will be in the overlapping state. In addition, the body part A and the cover part B may be respectively marked with marks so that the predetermined position where the hook 25 can pass through the notch 12a in the vertical direction is clear to the user at a glance. In this state, the user operates the handle 23 to rotate the lid B by a predetermined angle (for example, 15°) in a direction parallel to the overlapping surface with the main body A (hereinafter also referred to as a circumferential direction). In this way, the flange 12 fits into the hook 25, whereby the closing operation of the main body A and the cover B is completed. FIG. 1 shows a state in which the lid B is closed in this way. In addition, a stopper that restricts rotation over 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 securely engaged.

As described above, the inner lid 22 is detachably attached with the packing P for sealing between the inner lid 22 and (the opening peripheral portion of) the inner pot C. As shown in FIG. A structure for mounting the pad P will be described with reference to FIGS. 3 and 4 . FIG. 3 is an exploded perspective view of the cover B viewed from below, where the inner cover 22 is joined to the lower surface of the cover case K. As shown in FIG. The packing P is an annular cap packing along the inner peripheral shape of the inner cap 22 . The material of the pad P can be silicon rubber, fluororubber, neoprene and the like. The pad holder H holding the pad P includes a metal ring member 31 having a shape suitable for the shape of the pad P, and engaging members 30 are provided at, for example, three places of the ring member 31 . The gasket holder H is concentrically joined to the lower surface of the inner cover 22 by the joining member 30 . FIG. 4 shows a state where the gasket holder H is joined to the inner cover 22 with the joining member 30 .

A groove 32 is formed in the inner peripheral portion of the pad P. As shown in FIG. The packing P is attached to the inner cover 22 by fitting the ring member 31 of the packing holder H into the groove 32 of the packing P over the entire circumference. In a state where the inner pot C is accommodated 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.

The user can easily attach and detach the pad P. As shown in FIG. The user can detach the pad P and clean the pad P alone. When cooking, the user attaches the pad P to the inner lid 22 and stores the inner pot C in the storage portion 10 . Here, when the user forgets to attach the packing P to the inner cover 22 and starts cooking directly, the inner cover 22 and the inner pot C will not be in a sealed state, and therefore, the inside of the inner pot C cannot be heated. pressure, cooking cannot be performed normally. Even if the cooking is started immediately, the steam or moisture of the cooking material boiled in the inner pot C overflows from between the inner pot C and the inner lid 22 . In this case, too, there is a possibility that the overflowing moisture enters the inside of the main body, causing the cooker 100 to break down. In addition, when the user forgets to store the inner pot C in the storage part 10, cooking cannot be performed at all. Assuming that cooking is started immediately, electric power is supplied to the heating part without the inner pot C, and a so-called dry-fired state occurs. Therefore, there is a possibility that the cooker 100 may fail.

Based on the above, it is necessary to reliably prevent the situation of forgetting to attach the pad P to the inner lid 22 or forgetting to store the inner pot C in the accommodating portion 10 and immediately start cooking.

Therefore, the cooker 100 in this embodiment is provided with the prevention mechanism E, and at least any one state (first state) of the state where the inner pot C is not accommodated in the housing portion 10 and the state where the packing P is not attached to the inner lid 22 In this case, the preventing mechanism E restricts the rotation of the lid B (inner lid 22 ) for closing the lid B, thereby preventing the inner lid 22 from being locked by the locking mechanism D with the accommodating portion 10 . The preventing mechanism E will be described with reference to FIGS. 4 to 6 .

FIG. 5 shows an enlarged view of the upper end portion 11 of the main body case L on which the flange 12 of the housing portion 10 hangs. As shown in FIG. 5 , in the upper end portion 11 of the main body case L, a locking hole 52 having a shape dented downward is formed. The locking 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. The locking hole 52 may also be a step, a groove, or a recess formed by the peripheral wall 52a.

FIG. 4 shows the cover portion B where the gasket holder H is engaged with the inner cover 22 . Here, however, the pad P is removed. In FIG. 4 , a lock pin hole 60 is formed at a lower end portion of the lid case K (a portion overlapping with the upper end portion 11 of the main body case L when the lid portion B is closed). The blocking mechanism E can include a locking pin 61 that can pass through the locking pin hole 60 and move. The prevention mechanism E has a drive mechanism F that moves the lock pin 61 . In at least any one state (first state) of the state where the inner pot C is not accommodated in the housing portion 10 and the state where the packing P is not attached to the inner lid 22 (the first state), the drive mechanism F moves the lock pin 61 so that The front end of the lock pin 61 engages with the lock hole 52 to restrict the rotation of the lid B. As shown in FIG. In addition, in the state where the inner pot C is housed in the housing portion 10 and the packing P is attached to the inner lid 22 (second state), the drive mechanism F moves the lock pin 61 so that the front end of the lock pin 61 is disengaged. The hole 52 is locked, so that the restriction on the rotational movement of the cover part B is released. Details of the drive mechanism F are discussed subsequently with reference to FIG. 6 .

In the state where the packing P is removed as shown in FIG. 4 , the locking pin 61 protrudes from the lower end of the cover case K by the driving mechanism F. As shown in FIG. In this state, in order to close the cover B with respect to the main body A, when the cover B is placed on the main body A at a predetermined position where the hook 25 can pass through the notch 12a from top to bottom, the lock pin 61 enters into the lock hole 52 formed in the upper end 11 of the main body casing L. As shown in FIG. Therefore, even if the user tries to rotate the cover B in a direction parallel to the overlapping surface with the main body A, the cover B cannot be rotated because the lock pin 61 contacts the peripheral wall 52a of the lock hole 52 .

On the other hand, when the gasket P is attached to the inner lid 22 by the gasket holder H and the inner pot C is accommodated in the accommodating portion 10, under the action of the driving mechanism F, the top end of the lock pin 61 is disengaged from the lock. Through the hole 52, the locking pin 61 passes through the locking pin hole 60 and sinks into the cover shell K. As a result, the restriction on the rotation of the cover B in a direction parallel to the overlapping surface with the main body A is released, whereby the closing operation of the cover B can be performed.

A detailed configuration example of the drive mechanism F is shown in FIG. 6 . In FIG. 6, the lock pin 61 is arrange|positioned in the cover case K, and can pass through the lock pin hole 60 formed in the lower end part of cover case K, and can move. In addition, as shown in FIG. 4 , a pin hole 40 is formed in a portion of the inner cover 22 that can overlap the packing P attached to the inner cover 22 in plan view. The drive mechanism F may further include an abutment pin 62 which can pass through the pin hole 40 and move so as to abut against the pad P attached to the inner cover 22 . In a state where 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 connection member 63 that connects the abutment pin 62 and the lock pin 61 . With this coupling member 63 , the abutment pin 62 is linked with the lock pin 61 . The drive mechanism F also has a coil spring S as an urging member that urges the lock pin 61 in the direction in which the lock pin 61 protrudes from the lock pin hole 60 . A rod 66 is provided on the upper part of the inner wall 64 of the cover case K, and the rod 66 passes through a clearance fit hole (not shown) formed in the connecting member 63, and is connected with the lower surface of the top plate of the cover case K, and the coil spring S is It is arranged so as to surround this rod 66 . The rod 66 functions as a guide member that guides the movement of the coupling member 63 in a direction parallel to the axis of the lock pin 61 . Furthermore, a restricting member 67 that restricts lateral movement of the lock pin 61 may be provided inside the cover case K. As shown in FIG.

(a) of FIG. 6 shows a state in which the inner pot C is accommodated in the housing portion 10 and the packing P is attached to the inner lid 22 (second state), in order to close the lid portion B with respect to the main body portion A Instead, the cover portion B is placed on the main body portion A at a predetermined position where the hook 25 can pass through the notch 12 a from above to downward. In this case, the packing P pushed up by the inner pot C comes into contact with the contact pin 62 and pushes up the contact pin 62 against the urging force of the coil spring S. As shown in FIG. The locking pin 61 is interlocked with the contact pin 62 via the connecting member 63 , and the top end of the locking pin 61 is disengaged from the locking hole 52 . This is a state in which the restriction of the rotation of the lid B in the direction parallel to the overlapping surface overlapping the main body A is released, and the closing operation of the lid B is enabled.

(b) of FIG. 6 shows the following state: In the state where the packing P is attached to the inner lid 22 but the inner pot C is not accommodated in the accommodating portion 10, the lid portion B is closed in order to close the lid portion B relative to the main body portion A. 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 down. In this case, since there is no inner pot C, the pad P cannot push up the abutting pin 62, and the top end of the locking pin 61 is kept engaged with the locking hole 52 under the action of the force of the coil spring S. as is. This is a state in which the rotation of the cover B in a direction parallel to the overlapping surface overlapping the main body A is restricted, and the closing action of the cover B is prevented. In this way, when the liner P is installed on the inner cover 22, although the abutment pin 62 is in contact with the liner P, as long as the inner pot C is not accommodated in the accommodating portion 10, the locking pin 61 will not overcome the force of the coil spring S The lock pin 61 is moved so that the tip end portion of the lock pin 61 is disengaged from the lock hole 52 .

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

According to the embodiment described above, it is possible to reliably prevent the cooking from being started without attaching the detachable components (the pad P, the inner pot C).

The invention is not limited to the above-mentioned embodiments, and various modifications and changes can be made within the scope of the gist of the invention.
