Description

  The present invention relates to a cooking device.

  A rice cooker, which is one of the cookers, includes a rice cooker body that detachably accommodates a pan, and a lid that is pivotally connected to the rice cooker body by a connecting portion. An exhaust passage for discharging the exhaust in the pan to the outside is formed in the lid. Moreover, the inner cover which obstruct | occludes the upper end opening of a pan is arrange | positioned at the cover body. An exhaust hole communicating with the inside of the pan is formed in the inner lid, and a portion (upstream side) of the exhaust passage is formed between the inner lid and the lid body.

  Patent Document 1 describes a rice cooker in which an inner lid can be attached to and detached from a lid body so that the lower surface of the lid body and the upper surface of the inner lid can be cleaned. This rice cooker prevents misuse by preventing the lid body from being closed with respect to the rice cooker body when the lid is not fitted with an inner lid. The inner lid mounting portion for mounting the inner lid of the lid body is provided with a latch receiving portion for hooking and locking the inner lid on the connection portion side of the lid body. In addition, a locking member that locks the inner lid is slidably disposed on the tip side opposite to the locking receiving portion. In this locking member, when the inner lid is mounted, the locking receiving portion protrudes outward from the lid body, and the locking member of the rice cooker body is locked to the locking receiving portion. When the inner lid is not attached, the latch receiving portion is immersed in the lid body, and the lock member of the rice cooker body cannot be locked to the latch receiving portion. As a result, the lid cannot be kept closed with respect to the rice cooker body.

  Patent Document 2 describes a rice cooker in which a lid can be opened and closed smoothly (slowly) by a damper mechanism provided at a connection portion of the lid. The damper mechanism includes a hinge spring that urges the lid in the opening direction and a brake portion that slidably contacts the connecting portion, and a braking force acts against the urging force of the hinge spring due to friction caused by the slidable contact. ing. The braking force increases as the opening angle increases and becomes maximum at the maximum opening angle.

  Both the inner lid non-mounting prevention function of Patent Document 1 and the damper function of Patent Document 2 are often employed in one lid. However, when the user closes the lid body, the inner lid non-mounting prevention function of Patent Document 1 turns out that the lid body is rotated with respect to the rice cooker body, and the user cannot forget to attach the inner lid because it cannot be locked. There are many cases. In addition, the damper function of Patent Document 2 has a large relationship between the braking force of the lid body and the weight of the lid body. The heavier the braking force, the weaker the braking force, and the lighter the braking force, the stronger the braking force. Therefore, when the weight of the inner lid is heavy, there is an inconvenience that when the lid is noticed that the inner lid is not attached because the inner lid cannot be locked and the hand is released from the lid, the lid is vigorously opened. This problem becomes more prominent as the weight of the inner lid becomes heavier, and in the worst case, it leads to breakage of the connecting portion of the lid.

When the inner lid is mounted on the inner lid mounting portion, the interference portion is retracted toward the inside of the lid body, and the locking with the connection portion is released. In this case, the inner lid mounting portion includes a latch receiving portion that hooks and locks the inner lid on the connection portion side, and the lid regulating member is disposed so as to protrude into the latch receiving portion. ing. If it does in this way, simplification of the control mechanism which has a lid control member can be aimed at.

  In the cooker according to the present invention, when the inner lid is not attached to the lid, the user cannot recognize that the user has forgotten to attach the inner lid because the lid cannot be moved in the closing direction. In addition, since the lid body does not open vigorously by the biasing force of the hinge spring, it is possible to prevent the lid body from being damaged, and to reliably prevent misuse when used without the inner lid attached.

Further, the valve opening / closing member 114 has a cam portion for moving the valve body 106 upward in the advanced position to open the reflux hole 105 and moving the valve body 106 downward in the retracted position to seal the reflux hole 105. 116 is provided.

  Further, the inner lid set 66 of the present embodiment further includes an interference member 117 for preventing the lid 31 from being closed with respect to the cooker body 15 when the lower cover member 69 is not attached. It is arranged. The interference member 117 is disposed in an interference member cover 118 provided on the frame body 73 of the inner lid main body 67 so as to be positioned on the distal end side of the lid body 31. One lower cover locking receiving portion 77 is formed on the hinge connecting portion 24 side of the interference member cover 118. The interference member 117 is movable between a retracted position that does not interfere with the cooking pan 11 by mounting the lower cover member 69 and an advanced position that has advanced so as to interfere with the cooking pan 11 by removing the lower cover, It is urged to the advanced position by a spring (urging member) (not shown). The lower cover member 69 includes a pressing portion 119 that moves the interference member 117 to the retracted position by being attached to the inner lid main body 67.

  The inner lid set 66 configured in this manner closes the lid 31 when the four opening / closing valves 98 to 101, the valve opening / closing member 114 for opening and closing the interlocking reflux valve 101, and the lower cover member 69 are not attached. Since a large number of mechanisms such as the interference member 117 for preventing the interference are provided, the weight is heavy. The lid 31 equipped with the inner lid set 66 is much heavier than the conventional rice cooker or the like in terms of the weight of the plurality of drive mechanisms. Therefore, in order to open the lid 31 by operating the operating member 38, the biasing force in the opening direction by the hinge spring 40 is set large. Conversely, the braking force of a damper mechanism (not shown) that prevents the lid body 31 from opening vigorously is set to be extremely small. Therefore, in a state where the inner lid set 66 is not attached to the lid body 31, the weight is significantly reduced, so that the lid body 31 is vigorously moved by the biasing force of the hinge spring 40.

  However, in the cooking device 10 of the present embodiment, when the inner lid set 66 is removed from the lid body 31, the lid body 31 is provided with a lid regulating member 47 that engages with the hinge connection portion 24 of the cooking appliance body 15. When the inner lid set 66 is not attached, the lid body 31 cannot be rotated in the closing direction. Therefore, the user can immediately recognize that the user has forgotten to wear the inner lid set 66. Further, the lid body 31 cannot be rotated to a position where the lid body 31 is closed with respect to the cooker body 15. Therefore, the cover body 31 is not vigorously opened by the biasing force of the hinge spring 40. That is, since the lid 31 cannot be rotated unless the inner lid set 66 is attached, stable opening and closing can be realized. Therefore, breakage of the lid 31 can be prevented, and erroneous use of the inner lid set 66 without being attached can be reliably prevented.

  The lid regulating member 47 has a lid regulating member 47 because the hinge regulating portion 53 is engaged and disengaged with the hinge connecting portion 24 of the cooker body 15 by moving forward and backward by removing and attaching the inner lid set 66. The restriction mechanism can be simplified. The hinge locking portion 53 is provided with a guide edge 56 at the front edge of the lid 31 in the opening direction, and the inner lid set 66 is located at a position where the hinge locking portion 53 cannot be locked to the hinge connecting portion 24. Even if it is removed, the lid 31 is opened by the urging force of the hinge spring 40, and the hinge locking portion 53 can be locked to the hinge connecting portion 24. Therefore, convenience can be improved.

  In addition, the cooking device 10 of this invention is not limited to the structure of the said embodiment, A various change is possible.

  For example, in the embodiment, the hinge locking portion 53 is locked to the hinge connecting portion 24 in a state where the lid body 31 is rotated 90 degrees with respect to the cooker body 15. The opening angle at which 53 is locked can be changed as desired. Further, two or more locking step portions may be provided on the partition wall portion 25 of the hinge connection portion 24 so as to be locked at two or more open angles. Moreover, in the said embodiment, although the cover body 31 was connected with respect to the cooker main body 15 so that rotation was possible, you may arrange | position so that sliding is possible and it can comprise so that opening and closing is possible. In addition, the lid regulating member 47 is configured by one component disposed so as to be slidable. However, the lid regulating member 47 may be configured to be locked to the hinge connecting portion 24 using a link mechanism or the like.

  The present invention is characterized in that a lid regulating member 47 is provided that prevents the cooker body 15 from moving in the direction of closing the lid 31 when the inner lid set 66 is removed from the lid 31. Therefore, the cooker 10 is not limited to the cooker 10 that can cook various ingredients, and can be applied to a rice cooker that can only cook rice. Moreover, the apparatus which does not mount the damper mechanism which controls the opening speed of the cover body 31 may be sufficient. Moreover, it is not restricted to the structure which provides the cooker main body 15 which has a heating means, It applies also to the cooking pan 11 which arrange | positions the cover body 31 so that opening and closing is possible in the cooking pan 11, and uses the existing stove of a household kitchen as a heating means. Is possible.
