  In the rice cooker disclosed in Patent Document 1, the lid is biased in the opening direction by the spring provided on the hinge portion that pivotally supports the lid. The cooker body and the lid are usually made by resin molding and can be regarded as a rigid body. The lid is closed by the user pressing the lid against the biasing force. When closing the lid, if you accidentally put a finger in the gap between the upper outer periphery near the outer periphery of the upper end of the cooker body and the lower outer periphery near the outer periphery of the lower end of the lid, the cooker body whose fingers are rigid And there is a risk of interfering with the lid. The conventional rice cooker is not provided with any special measures for preventing unintentional interference of fingers with the cooker body and the lid due to pinching of fingers.

  Therefore, the technical problem to be solved by the present invention is to provide a cooking device which can prevent unintended interference of fingers with the cooking device body and the lid.

  In order to solve the above technical problems, according to the present invention, the following heating cooker is provided.

That is, the heating cooker according to the present invention is
A cooker body that accommodates the pot,
And a lid body configured to be pivotable by a hinge on the cooker body, covering an upper portion of the pan.
A flexible gap buffer may be disposed in a gap between the upper end outer peripheral portion of the cooker main body and the lower end outer peripheral portion of the lid.

  In the present invention, a flexible gap cushioning body 50 is disposed in the gap between the upper end outer peripheral portion of the cooker main body 10 and the lower end outer peripheral portion of the lid 11, thereby making it possible to Even if a finger is caught in the gap, the gap cushioning body is flexibly and elastically bent to function as a member that buffers the pinch. Therefore, it is effective in the ability to prevent the unintended interference of the finger with respect to the cooker main body and the cover body by pinching of the finger.

  It is preferable that the said space | interval buffer body has a U-shape opened toward the inner side of the said heating cooker by cross sectional view.

In this way, even if a gap is produced between the gap buffer attached to either the cooker body or the lid and either one, the skirt can reliably hide the gap, and the appearance The design is clean and aesthetics are improved.

  When the lid is pushed down, the pinching force becomes smaller as the part is farther from the hinge, so even if the gap at the front side part is narrowed, the damage caused by the pinching of fingers may be small. On the other hand, if the gap at the rear side with the hinge is not wide, the damage when the finger is pinched will increase. Therefore, it is preferable that the gap is sized to be wider at the rear side with the hinge than at the front side. In this way, by narrowing the gap at the front side portion, the viewer is given an impression that the front is squeezed down, the appearance is clean, and the aesthetics is improved.

  It is preferable that the said space | interval buffer body is detachably attached to the said cooker main body or the said cover body. In this way, the gap buffer can be removed and cleaned, and the gap buffer can be kept clean.

  It is preferable that a sensor for detecting attachment and detachment of the gap buffer is disposed. In this way, heating and cooking can be prevented from being performed with the gap buffer removed.

  Preferably, the lid is closed by an electric motor. In this way, the closing operation of the lid can be performed automatically and smoothly.

  It is preferable that the gap buffer has a U-shape that is open toward the rear with the hinge in a plan view. In this way, the front portion and both side portions where finger pinching is likely to occur can be reliably protected by the gap buffer.

  In the heating cooker according to the present invention, since the gap cushioning body is flexible and elastically bent, it is possible to prevent unintended interference of fingers with the cooker body and the lid.

In this way, by forming the gap A on the front side narrow, the viewer is given an impression that the front is squeezed, the design is clean in appearance, and the aesthetics is improved.

  The front side gap A has a substantially constant gap size in the left and right lateral directions. The gap B on the rear side starts from a gap size similar to the gap A on the front side in the front-rear direction, and after the gap size gradually increases, becomes a substantially constant gap size. The gap A on the front side and the gap B on the rear side are sized so as not to hurt even if a finger is caught in the gaps A and B. If the numerical value which does not limit this invention is illustrated, the size of gap A on the front side is 5 mm to 10 mm, preferably 7 mm to 9 mm, more preferably 7.5 mm to 8.5 mm. Also, the size of the gap B on the rear side is 10 mm to 20 mm, preferably 12 mm to 18 mm, and more preferably 14.5 mm to 15.5 mm.

  The gap buffer 50 is dimensioned to be attached to the gaps A and B formed between the side surface of the rice cooker body 10 and the side surface of the lid 11. As shown in FIG. 5, the gap buffer 50 is U-shaped having three sides in a plan view, and has a shape opened toward the rear side with a hinge. According to the said structure, the site | part of the front side which pinching of a finger | toe tends to generate | occur | produce, and the site | part of the both-sides on either side are protected by the space | interval buffer body 50. FIG. In addition, the gap cushioning body 50 may further include one side extending in the lateral direction in the vicinity of the hinge connection portion 21 and may have a rectangular shape having four sides in a plan view.

  The gap buffer 50 has flexibility, and is made of, for example, a rubber material such as silicone rubber, fluorine rubber or urethane rubber, or a polymeric elastic material such as an elastomer material. The flexible gap buffer 50 functions as a member that softly and elastically bends when fingers are caught in the gaps A and B, thereby buffering finger pinching. Therefore, it is effective in the ability to prevent the unintended interference of the finger with respect to the rice cooker main body 10 and the cover body 11 by pinching of the finger.

  As shown in FIG. 6, the gap buffer body 50 is U-shaped in a cross-sectional view, and has a shape opened toward the inside of the pressure cooker 1. The gap cushioning body 50 has a support rib portion 54, a base portion 52 and a reinforcing rib portion 58 which form a U-shape. The base portion 52 extends in the vertical direction, and the support rib portion 54 and the reinforcing rib portion 58 extend in the lateral direction from the upper and lower portions of the base portion 52, respectively. According to the said structure, in addition to a space | interval buffer body 50 having shape retention property, the space | interval space 51 is formed of the part enclosed by U shape. The gap buffer 50 including the gap space 51 can reduce damage due to pinching of fingers more than when it is configured from a solid body. Moreover, since the gap space 51 works as a heat insulation space, the heat retention property is improved.

  An engagement portion 56 that protrudes upward and extends in a U-shape in a plan view is formed at the center of the upper surface of the support rib portion 54. The engagement portion 56 has a plurality of locking projections 57 on its side surface, and is fitted into the engagement recess 27 formed in a groove shape in a U shape in plan view at the inner member 26 of the lid 11. The gap buffer body 50 is configured to be removable from the lid 11 by the engagement structure of the engagement portion 56 and the engagement recess 27. According to the said structure, the clearance gap buffer 50 can be removed from the lid 11, and can be wash | cleaned, and the clearance gap buffer 50 can be maintained in a clean state.

  In order to facilitate the positioning of the gap buffer body 50 with respect to the rice cooker body 10, a plurality of positioning protrusions 55 are disposed apart from each other on the inner peripheral portion of the engagement portion 56. The positioning projection 55 engages with a notch (not shown) formed in the inner member 26. Therefore, the gap buffer 50 can be attached to a predetermined position of the rice cooker body 10.

  In the cross-sectional view of FIG. 6, a cover portion 53 extending upward is formed at a portion where the base portion 52 and the support rib portion 54 intersect. In the cross-sectional view of FIG. 7, the cover portion 53 overlaps the lower end of the side surface of the lid 11 and covers and hides the lower end of the side surface of the lid 11. According to the said structure, it becomes an appearance-clear design and an aesthetics improves.

  In the cross-sectional view of FIG. 6, a skirt portion 59 extending downward is formed at a portion where the base portion 52 and the reinforcing rib portion 58 intersect. In the cross-sectional view of FIG. 7, the skirt portion 59 overlaps the upper end of the side surface of the body decoration 36 mounted on the outer peripheral upper portion of the shoulder body 32 and hides the upper end of the side surface of the body decoration 36. The skirt portion 59 of the gap buffer 50 attached to the lid 11 extends so as to overlap the upper end of the side surface of the rice cooker body 10. When the gap buffer 50 is attached to the rice cooker body 10, the skirt portion 59 of the gap buffer 50 extends so as to overlap the lower end of the side surface of the lid 11.

  Due to the presence of component tolerances and assembly tolerances, a closure gap of about 1 mm is practically formed between the lower surface of the reinforcing rib 58 and the upper surface of the shoulder cover 34 even in the closed state of the lid 11 . By providing the skirt portion 59, the closed gap is hidden. As described above, the skirt portion 29 makes the appearance clear in design and improves the aesthetics. Further, the heat flow can be prevented from flowing as it is in the lateral direction (substantially horizontal direction) as it is by the skirt portion 29 so that the heat retention property is improved.

  Further, a shock absorber detection sensor 60 for detecting attachment and detachment of the gap shock absorber 50 is provided on the inner member 26. The buffer detection sensor 60 is, for example, a physical sensor such as a micro switch or a reed switch, or an optical sensor such as a photo interrupter. As shown in FIG. 8, the buffer detection sensor 60 is connected to the microcomputer 5 (control unit), and the microcomputer 5 (control unit) controls ON / OFF of energization of various heaters. By providing the buffer detection sensor 60, careless heating and cooking can be prevented from being performed with the gap buffer 50 removed.

  In addition, in order to make an understanding of this invention easy, although it demonstrated using a specific structure and number, this invention is not limited to the specific structure or number of each embodiment mentioned above, Various modifications can be included without departing from the scope of the claims.

  For example, the front side gap A and the rear side gap B may be sized to be substantially the same gap size. In addition, the gap buffer 50 may not have the skirt portion 59, and the base portion 52 may end in the reinforcing rib portion 58. In addition, the gap cushioning body 50 may be configured as a porous base portion 52 having a wide thickness and being sponge-like without having the support rib portion 54 and the reinforcing rib portion 58. Further, there may be a mode in which there is no closing gap between the lower surface of the reinforcing rib portion 58 and the upper surface of the shoulder cover 34, and the lower surface of the reinforcing rib portion 58 abuts on the upper surface of the shoulder cover 34. . Also, the gap buffer 50 may be a non-removable fixed type. The present invention can be applied to those in which the lid 11 is automatically closed by an electric motor, and those in which the lid 11 is manually closed.
