Problems solved by technology

[0012] However, in the above-mentioned configuration, only the rear end 104a of the inner cover 104 is locked to the inner cover locking part 105, so there is a possibility that the inner cover 104 may be dislodged from the inner cover 104 due to the centrifugal force during the rotational movement together with the cover main body 103. The locking part 105 of the inner cover flies out, or the inner cover 104 deviates from the inner cover installation position of the cover main body 103, so that the inner cover 104 cannot be placed correctly
If the inner lid 104 deviates from the inner lid installation position and starts cooking in the state of being installed on the inner lid installation part 105, then the inner lid gasket 108 of the inner lid 104 may not be in close contact with the pot 102. Leaking from between the inner lid liner 108 and the pot 102, the temperature of the space inside the pot 102 will drop, resulting in the failure of cooking

[0166] Figure 15 It is sectional drawing which shows the structure of the rice cooker concerning 2nd Embodiment of this invention. The rice cooker according to the second embodiment of the present invention is different from the first embodiment in that it further includes a fixed portion guide wall 16d. The other structure is the same as that of the rice cooker of 1st Embodiment, Therefore, a duplicate description is abbreviate|omitted, and a different point is mainly demonstrated.

[0167] exist Figure 15Among them, the fixed portion guide wall 16d is formed so as to converge from the front end portion of the hook (inner lid adjusting portion) 14 toward the inner lid attaching position 4A. More specifically, the fixed portion guide wall 16d is inclined so as to approach the inner lid attachment position 4A toward the hinge axis D. As shown in FIG. Here, similarly to the inclined surface (lower curved surface portion) 14a of the hook 14, the fixed portion 4d of the inner...

[0175] Figure 17 It is a partial enlarged cross-sectional view of the rice cooker concerning 3rd Embodiment of this invention. The rice cooker of the third embodiment of the present invention is different from the rice cooker of the first embodiment in that the inner lid locking portion 12 has a damper portion 18 in place of the locking protrusion 12b. The other structure is the same as that of the rice cooker of 1st Embodiment, Therefore, a duplicate description is abbreviate|omitted, and a different point is mainly demonstrated.

[0176] like Figure 17 As shown, in the rice cooker of 3rd Embodiment of this invention, the side wall of the lid main body 3 side of the groove part 12a is comprised by the buffer part 18. The buffer portion 18 includes a friction wall (friction portion) 18b provided so as to be movable in the front-rear direction with respect to the side wall 12h on the side of the pot 12a, and a spring 18a for urging the friction wall 18b toward the side wall...

Abstract

The present invention provides an electric cooker, which can fix the inner cover on the inner cover installation device of the cover main body easily. The mentioned electric cooker contains: electric cooker main body with a house part for containing holloware in the mentioned electric cooker; holloware which is detained in the house part; holloware heating device to induce heating holloware; cover main body of opening part to open / close the electric cooker; inner cover of opening part to seal holloware; inner cover locking-stopping guiding part which sets on the cover main body and can pluggable lock the inner cover which is released the fixation from the inner cover installation position and falls towards the side aparting from the cover main body on the inclined position relative to theinner cover installation position under the state that cover main body is open, and to make the cover main body guide the inner cover to the inner cover installation position when it changes from theopening state to the closing state under the state that the inner cover is locked on the inclined position.

Description

technical field [0001] The present invention relates to a rice cooker with an inner cover. Background technique [0002] Conventionally, there has been proposed a rice cooker in which a user can easily detach the inner lid from the lid main body with one hand (for example, refer to Patent Document 1 (Japanese Patent Laid-Open No. 2002-95580 )). [0003] Figure 26 It is sectional drawing which shows the structure of the conventional rice cooker described in patent document 1. like Figure 26 As shown, the conventional rice cooker includes a rice cooker body 101 having a substantially bottomed cylindrical shape, a pot 102 accommodated in the rice cooker body 101, an opening that can open and close the rice cooker body 101, and is attached to the rice cooker body 101. The lid body 103 on the pot body 101 is detachably attached to the inner side of the lid body 103 (the side covering the opening of the pot 102 ) and a disk-shaped inner lid 104 that seals the opening of the pot...
