[Problems to be solved by the invention]
  However, the cooker of the above-described conventional example 1 holds the cord reel between the lower frame and the bottom of the protective frame, and fixes the nail provided on the lower frame and the protruding portion of the cord reel. Since it is temporarily fixed, it is not only necessary to provide the above-mentioned claws and protrusions, but also requires a temporary fixing operation, and the assembly work of the cord reel is complicated. And since the trunk | drum and bottom part (lower frame) of a main body case are separate bodies, the assembly | attachment process for couple | bonding both was required.
[0007]
  In addition, since the cord reel of the conventional example 1 is not provided with a cover member that covers the cord reel like the mounting member of the present invention, water droplets from the inner peripheral surface of the lid, or spilling from the steam pressure control portion. The stick is likely to enter from the vicinity of the hinge portion of the lid, and in some cases, there is a possibility that the water droplets or sticky moisture may be applied to the charging terminal portion of the cord reel.
[0008]
  Further, the cord reel of Conventional Example 1 does not adopt a configuration that can adjust the storage height of the cord reel when the cord reel is arranged vertically in the internal space of the rice cooker body. For example, a 1 liter (5.5 go) cooked rice cooker and a 1.8 liter (1 炊) cooked rice cooker have different height dimensions, so the diameter code is the optimum size corresponding to the height dimension. At present, the reels are separately manufactured and attached, and the cord reel of the conventional example 1 is the same as the above-mentioned current product. That is, the cord reel of Conventional Example 1 cannot be used even for rice cookers having different height dimensions, that is, different sizes.
[0009]
  The electric rice cooker of Conventional Example 2 also has the same problems as in Conventional Example 1. These problems will be described in detail below.
  That is, the cord reel of Conventional Example 2 includes a winding portion and a case-type holder that is open on one side for storing the winding portion, and is an upper surface of a bottom portion formed below the inner surface of the side wall and rear end wall of the body member. The holder is provided with a rib for supporting the holder, a pair of support pieces, and a screw hole projection, and the holder is provided with a bifurcated piece, and the cord reel is assembled to the main body case with these members. Therefore, there are problems such as requiring a large number of these assembling members and troublesome in assembling them.
[0010]
  The cord reel of Conventional Example 2 stores and holds the winding portion with a holder, but does not include a cover member that covers the charging terminal portion of the winding portion, so water droplets or steam from the inner peripheral surface of the lid There is a possibility that the spilled from the pressure adjusting part easily invades from the vicinity of the hinge part of the lid, and in some cases, the water droplets or the water of the squirrel may be applied to the charging terminal part of the cord reel.
[0011]
  Furthermore, the cord reel of Conventional Example 2 is not configured to adjust the storage height of the cord reel when the cord reel is arranged vertically in the internal space of the rice cooker body. For this reason, the cord reel of Conventional Example 2 cannot be used even for rice cookers having different height dimensions (that is, sizes).
[0012]
  The present invention solves the above-described conventional problems, is excellent in workability of attaching the cord reel to the rice cooker body, prevents the charging terminal portion of the cord reel from being exposed to water droplets or sticky water, and further It aims at providing the electric rice cooker which can respond also to the rice cooker from which height differs with the same cord reel by adjusting storage height.

  As described above, the mounting member 60 shown in this embodiment is formed by the eaves 61 and the side plate 62, and the side plate 62 has a leg portion 67 that covers the charging terminal portion 54. Since the upper portion of the cord reel 50 is covered and the leg portion 67 covers the charging terminal portion 54 of the cord reel 50, for example, as shown in FIG. The possibility that the water droplets from the inner peripheral surface of the lid 20 or the moisture of the squirt that spills from the steam pressure adjusting portion will be applied to the charging terminal portion 54 is surely eliminated. In FIG. 6, reference numeral 95 denotes a water drop or a rice bowl.
[0041]
  In order to further secure the above object, in the present embodiment, as shown in FIG. 5, the second eaves 80 and the third eaves 80 are disposed between the eaves 61 and the upper portions of the leg portions 67 on the back surface side of the side plate 62. In the unlikely event that the eaves 61 cannot prevent the moisture of the water drop from dropping directly below the charging terminal portion 54, the second eaves 80 and the third eaves 81 prevents it.
[0042]
  In the electric rice cooker in this embodiment, an assembly example of the cord reel 50 and the attachment member 60 will be briefly described below with reference to FIGS.
  First, the female screw portion 55 of the cord reel 50 that is oriented vertically is aligned with any of the mounting holes 70 to 72 formed in the leg portion 67 of the mounting member 60 and fixed with the screw 73, and the height is adjusted. Any one of the mounting holes 75 to 77 as the portion 74 is fixed with a screw 78. Next, the screw holes 63 and 64 formed in the eaves 61 of the mounting member 60 are aligned with the bosses 66 and 66 formed in the shoulder 4 and fixed with screws 65 and 65. As a result, the cord reel 50 is suspended from the shoulder 4 via the attachment member 60. After that, the plug 53 of the power cord 51 of the cord reel 50 is exposed from the cord outlet of the rice cooker body 1 or all other wiring is terminated. Finally, the outer case 2 is fitted to the shoulder 4.
[0043]
  Thus, in this embodiment, compared with the conventional example which requires a temporary fixing member or a temporary fixing operation, the cord reel can be easily and easily assembled to the shoulder portion in the internal space of the rice cooker body, Assembly work efficiency can be improved.
[0044]
