JP 2005-95569 A

  In Patent Document 1, an upper first lid member and a lower second lid member are provided, a decorative cover is disposed on the upper surface of the first lid member, and an inner lid is provided on the lower surface of the second lid member. There is provided a lid of an instrument that is detachably disposed. The decorative cover has a slightly smaller shape in plan view of the first lid member, and a number of engaging claws that maintain the attached state by plastic deformation are formed on the outer peripheral edge thereof. Further, the first lid member is provided with a shallow concave portion for disposing the decorative cover, and an engagement hole through which the engagement claw penetrates is provided on the outer peripheral edge thereof.

  However, with this fixing structure, the metal decorative cover cannot be disposed so as to cover the outer peripheral edge of the lid. Moreover, when it is set as the shape which covers to an outer periphery, since the outer periphery of a metal decoration cover is exposed, there is a problem in safety and it cannot be put into practical use.

  By the way, in the case of a form similar to a container that is not hingedly connected to the instrument body, such as a lid of a water bottle, a housing groove that is recessed inward is provided at the opening edge of the resin lid body disposed inside, By fitting the opening edge of the decorative cover into the receiving groove, the edge of the decorative cover is prevented from being exposed. However, this form has a poor workability to bend and attach a metallic decorative cover, and is further difficult to remove, and cannot be used for an instrument requiring maintenance.

  The present invention has been made in view of conventional problems, and it is an object of the present invention to provide an instrument lid capable of disposing a decorative cover in a desired region without limiting the disposition region. is there.

  In order to solve the above-described problem, the lid of the instrument of the present invention is a lid that closes the opening of the instrument body so as to be openable and closable, and is provided with two or more locking pieces protruding downward on the outer peripheral part. A first cover member, a decorative cover that covers at least a part of the upper surface of the first cover member, and that has a flange portion that protrudes inwardly on an outer peripheral edge and that the locking pieces are locked to the upper surface; It is set as the structure provided with the 2nd cover member arrange | positioned under the 1 cover member and the outer peripheral part overlaps with the lower surface of the flange part of the said decorative cover.

  It is preferable that the lid body of the instrument is provided with a hinge connection part attached to the second lid member so as to be openable and closable to the instrument body.

  In the lid of the instrument of the present invention, the decorative cover is provided with a flange portion projecting inward, and the flange portion is fixed so as to be sandwiched between the first lid member and the second lid member. Decorative cover can be arranged up to. Moreover, since the outer peripheral edge of the decorative cover is not exposed, the user is not injured at the edge.

  In addition, when the lid is assembled, the decorative cover is disposed on the first lid member, so that the locking pieces and the flanges can be locked in a state in which they cannot be detached. In the state, the first lid member and the second lid member are fixed to each other. That is, instead of positioning and fixing the three members at predetermined positions, it is only necessary to fix the two parts individually, so that the assembly workability can be improved. On the other hand, when removing for maintenance, etc., after disassembling the first lid member and the second lid member, it is relatively easy to disassemble the decorative cover by elastically bending the locking piece of the first lid member. Can be disassembled.

And radial ribs 28 extending radially outward from the center of the. These ribs 27 and 28 also play a role of abutting and positioning on the inner surface of a decorative cover 49 described later. The first lid member 26 has a dimension in the front-rear direction extending substantially over the entire length of the lid body 25 and a dimension in the left-right direction smaller than the entire width of the lid body 25. A fan-shaped exhaust part 29 is provided on the back side of the first lid member 26 so as to cover the hinge connection part 16. Further, an exposed portion 30 formed of a circular opening is provided on the front side of the first lid member 26. The exposed portion 30 exposes the release button 31 having the lock portion 31a, and a bearing portion 32 is provided on the inner back portion thereof. A side wall 33 extending vertically downward is provided on the side surface of the first lid member 26, and four side walls (two on the back side are not shown) projecting to curve downward on the side wall 33. An elastic locking piece 34 is provided. In addition, the front side outer periphery of the 1st cover member 26 comprises the wide locking piece 35 which hardly comprises elasticity. Further, on the lower surface of the first lid member 26, a screwing portion 36 (see FIG. 5) for tightening a screw is projected.

  The second lid member 37 is made of resin and is fixed to the lower side of the first lid member 26 by screws, and has a circular shape in plan view that is substantially the same as the front / rear and left / right dimensions of the lid body 25. . The second lid member 37 has a reverse saucer shape raised upward, and its outer peripheral edge 38 protrudes in the horizontal direction toward the radially outer side and has a circular shape slightly smaller than a decorative cover 49 described later. It is formed and is configured so that it can hardly be seen visually. On the upper surface of the second lid member 37, reinforcing ribs 39 that abut against the lower surface of the first lid member 26 are projected so as to form a lattice shape in plan view. Further, on the back side of the second lid member 37, a connection portion 40 for being attached to the hinge connection portion 16 so as to be openable and closable is provided, and an exhaust cylinder portion 41 connected to the exhaust portion 29 is provided. The second lid member 37 is provided with a screw insertion hole 42 (see FIG. 5) corresponding to the screwing portion 36. Further, a through-hole 43 through which the lock part 31 a of the release button 31 passes is provided on the front side of the second lid member 37. An inner lid attaching portion 44 is provided at the lower portion of the second lid member 37. As shown in FIG. 2, the inner lid 45 attached to the inner lid attaching portion 44 is provided with a seal member 47 that seals the opening edge of the rice cooker 11 on the outer peripheral portion of the metal inner lid main body 46, and the exhaust lid 45. An exhaust member 48 that penetrates the cylinder portion 41 and enters the exhaust portion 29 is provided.

  As shown in FIG. 4, the decorative cover 49 is made of metal (stainless steel) having a mirror finish like the body 13, and the exhaust portion 29 of the first lid member 26 and the release button 31 in the exposed portion are provided. The shape covers the entire surface of the first lid member 26 except for the above. Specifically, the decorative cover 49 has a circular shape in a plan view that curves upward, and is provided with a fan-shaped notch 50 at a position corresponding to the exhaust portion 29 of the first lid member 26 and an exposed portion. An exposure hole 51 is provided at a position corresponding to 30. On the inner peripheral edge of the notch 50 and the exposure hole 51, a folded portion 52 that protrudes inward is provided. In addition, an engagement claw 53 that protrudes further downward from the tip of the folded portion 52 is provided at the top that is the inner end closest to the center in the notch 50 and the position closest to the center in the exposure hole 51. . And in this embodiment, the flange part 54 which protrudes in a horizontal direction toward radial inside is provided in the outer periphery except the said notch part 50. As shown in FIG.

  When assembling the lid body 25 having the above-described configuration, first, the decorative cover 49 is disposed on the first lid member 26, and the decorative cover 49 is pressed against the first lid member 26. As a result, the elastic locking piece 34 of the first lid member 26 comes into contact with the inner end edge of the flange portion 54 of the decorative cover 49, and the elastic locking piece 34 is elastically bent inwardly. When the tip exceeds the inner edge of the flange portion 54, the elastic locking piece 34 is locked to the upper surface of the flange portion 54. When the first lid member 26 and the decorative cover 49 are assembled, the front locking piece 35 hardly bends. Therefore, after the locking piece 35 is locked to the upper surface of the flange portion 54, the rear side is It is preferable to lock by pressing. Thereafter, the engaging claw 53 is bent to fix the decorative cover 49 and the first lid member 26 so that they cannot be detached. Here, the engaging claw 53 of the notch 50 passes through a through hole (not shown) formed in the first lid member 26 and is bent on the inner surface side of the first lid member 26. Further, the engaging claw 53 of the exposure hole 51 is bent on the inner surface side of the first lid member 26 through the inner peripheral edge of the exposed portion 30.

  In this way, when the first lid member 26 and the decorative cover 49 are locked so as not to be detached, the first lid member and the second lid member 37 are then adjusted in position and screwed together. A screw is fastened to the portion 36 and fixed. Thereafter, the connecting portion 40 of the second lid member 37 is pivotally attached to the hinge connecting portion 16 of the instrument main body 12 in a state where the lid body 25 is biased in the opening direction by the hinge spring.

  As described above, the lid body 25 of the present embodiment is configured by the three parts 26, 37, and 49. However, the first lid member 26 and the decorative cover 49 are not positioned and fixed at a time. Since the first lid member 26 and the second lid member 37 are individually fixed, positioning workability is good, and as a result, assembly workability can be improved.

  Further, as shown in FIG. 5, the cover body 25 in this assembled state is provided with a decorative cover 49 over almost the entire surface so as to cover the outer peripheral edge, so that the appearance can be improved and the cleaning property can be improved. It can be improved. In addition, in the decorative cover 49, the elastic locking piece 34 of the first lid member 26 is locked to the upper surface of the flange portion 54 provided so as to protrude inward, and the second lid member 37 is locked to the lower surface of the flange portion 54. The outer peripheral edge portion 38 is superposed. Thus, since it has the structure which covers and covers the edge part of the metallic decorative cover 49, the user's hand does not get injured by interference with the edge.

  Further, when removing (disassembling) the lid body 25 during maintenance or the like, after disassembling the first lid member 26 and the second lid member 37, the locking piece 35 of the first lid member 26 is elastically moved. By bending, the decorative cover 49 can be disassembled relatively easily. Therefore, it is particularly effective in the case of household electrical appliances that require maintenance, such as the rice cooker 10 of the present embodiment.

  In addition, the cover body 25 of the instrument of the present invention is not limited to the configuration of the above embodiment, and various modifications can be made.

  For example, in the above-described embodiment, the large cutout portion 50 is provided in the decorative cover 49 to expose the exhaust portion 29, but only the hole of the exhaust portion 29 is exposed like the exposure hole 51 that exposes the release button 31. It is good also as a structure which provided the hole like this.

  Moreover, in the said embodiment, although the decorative cover 49 was made into the shape which covers substantially the whole 1st cover member 26, if it is a structure which covers at least one part of the outer peripheral part of the 1st cover member 26, it is applicable. . In this case, it is preferable to provide the engaging claw 53 according to the locking state based on the covering region. Incidentally, as in the above-described embodiment, when the cover is covered with the decorative cover 49 over substantially the entire circumference, the engagement claw 53 may not be provided. Thus, in the lid body 25 of the present invention, the arrangement area of the decorative cover 49 where the screwing portion 36 cannot be formed is not limited and can be arranged in a desired area.

  Furthermore, in the said embodiment, although the instrument which applies the cover body 25 of this invention was made into the rice cooker 10, if it is an instrument which requires a cover body, such as an electric pot, it is applicable similarly. However, as a device to which the lid body 25 of the present invention is applied, especially if the lid body 25 is pivotally attached to the device body 12 so as to be openable and closable and a resin part is essential. It is valid.

It is a perspective view which shows the rice cooker which is an instrument provided with the cover body of this invention. It is a center longitudinal cross-sectional view of FIG. It is a top view of FIG. It is a disassembled perspective view of a cover body. It is principal part sectional drawing which cut | disconnected the cover body from the front side to the side part.
