Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an electric rice cooker, and more particularly to a storage structure for a cord reel.

[Prior Art] When attaching a cord reel to an electric rice cooker, the
As shown in the figure, a method is provided in which a recess 2 is provided on the outer surface of the body member 1 and the cord reel 3 is fixed in the recess 2 in the vertical direction. Alternatively, as shown in FIG. 8, the cord reel 3 may be laterally fixed to the recess 2 on the bottom surface of the body member 1.

[Problems to be solved by the device]

However, the vertical mounting method as shown in FIG. 7 requires a cover for closing the recess 2 formed on the side surface of the body member 1, which causes a problem of impairing the appearance of the outer surface of the body member 1. In addition, as shown in FIG.
Since the cord reel 3 is located immediately below, it is necessary to avoid thermal influences, which causes an increase in the total height of the product.

Then, this invention makes it a technical subject to solve the said problem by attaching a cord reel inside the trunk | drum member.

[Means for Solving the Problems]

In order to solve the above problems, the present invention relates to an electric rice cooker in which a cord reel is integrally attached to a part of a body member, and the cord reel is configured by a winding portion and a case-shaped holder with one side open. , The holder is provided with the winding section, the body member is provided with a cord outlet, the cord reel is interposed between the inner surface of the body member and the outer pot, and the open surface of the holder is connected to the body. The holder is fixed to the body member so as to face the inner surface of the member, and the tip of the plug protruding from the cord reel is inserted into the cord outlet.

[Action]

When connecting the cord to the power supply, pull out the cord by pinching the exposed plug from the cord outlet of the body member. When the pulling out of the cord is stopped, it is held at that position by the internal mechanism of the cord reel. When the cord is stored, if the above constraint is released, the cord is automatically wound by the force of the spring in the cord reel.

Further, since the holder constituting the cord reel is attached with the open surface thereof facing the body member side, it is possible to prevent the take-up portion housed therein from being thermally affected.

〔Example〕

FIG. 1 is an example of an electric rice cooker, which has a body member 10, a shoulder member 11, a pot 12 and a lid 13, and is formed at the lower rear end of one side wall 14 of the body member 10. A cord outlet 16 (see FIG. 2) is provided in the recess 15. The tip portion of the plug 17 is exposed from the cord outlet 16.

As shown in FIG. 3, the cord reel 18 has a winding portion 20 housed in a flat case-shaped holder 19, and a power supply lead wire 21 is connected to the winding portion 20. Holder 19
An inclined surface 22 is formed on a part of the side surface of the, and a hook 23 is provided on the inclined surface 22. By hooking the lead wire 21 on the hook 23, the lifting of the lead wire 21 is prevented.

The inner wall surface 24 of the recess 15 formed at the lower rear end of one side wall 14 of the body member 10 is inclined toward the side wall 14 toward the rear as shown in FIGS. 3 and 4. is doing. The cord outlet 16 is formed on the inclined wall surface 24.

The width of the cord outlet 16 matches the width of the holder 19 (see FIG. 4). The cord outlet 16 is formed by cutting into the upper wall surface 25 of the recess 15, and a side cut 27 is provided on one side of the cut 26.

In addition, bottom portions 29, 29 that are bent inward are provided on the inner surface lower portions of the side wall 14 and the rear end wall 28 of the body member 10, and a rib 30 that receives the lower end surface of the holder 19 is provided on the upper surface of the bottom portion 29. 19
A pair of opposing support pieces 31 and screw hole projecting portions 32 that support the lower portions of both side surfaces from both sides are provided.

The cord reel 18 is arranged along the inner side of the rear end wall 28 of the body member 10 and in a state of being slightly inclined as shown by a chain double-dashed line in FIG. This cord reel 18 is a holder while inserting the plug 17 into the outlet 16 as shown by the chain line in FIG.
One end of 19 is fitted into the notch 26 of the cord outlet 16, and at the same time, the retaining projection 33 provided at one end of the holder 19 is fitted into the side notch 27. The bottom surface of the holder 19 is rib 30
It is placed on top and held by the support pieces 31 on both sides. Further, the forked piece 34 provided on the holder 19 is fixed to the screw hole projecting portion 32 with a screw 35.

FIG. 6 shows the positional relationship of the cord reel 18 described above. The cord reel 18 is arranged between the rear end wall 28 of the barrel member 10 and the outer hook 36.

In this case, the holder 19 protects the winding portion 20 from thermal influence, so that the closed surface of the holder 19 faces the inside and the open surface faces the outside.

It should be noted that the holder 19 should be
A heat insulating material 37 is interposed between the outer pot 36 and the outer pot 36.

In addition, on the outer surface of the body member 10, the scooping receiver 40 is attached to the upper portion of the above-mentioned cord outlet 16. The rice scoop receiver 40, as shown in FIGS. 3, 4 and 5,
On the surface facing the body member 10, an engaging claw 41 having a lateral L-shaped cross section is provided in a protruding manner. The engaging claw 41 is a horizontally long hole provided on the side wall 14 of the body member 10.
It is inserted into 42 and is forcedly fitted into an engaging hole 43 provided in the shoulder member 11 fitted along the inside of the laterally long hole 42.

Further, as shown in FIG. 6, a deep recess 45 opened downward is integrally formed inside the front end wall 44 of the body member 10, and a mounting board 46 of an electronic component is inserted into the recess 45. It Recess 45
The lower end open portion of the is closed by a closing lid 47. Also recess
A protrusion 48 protruding upward from the ceiling portion of 45 is coupled to the shoulder member 11 by a screw 49. With this configuration, the outer pot
Even if water is accidentally introduced into 36, the substrate 46 is not splashed with water, and the side surface portion is lower in temperature than the bottom portion, so that the influence on the substrate 46 is small.

Further, in the electric rice cooker of the embodiment, the flat portion 52 is provided on the surface of the heating plate 51 around the temperature sensor 50 at the bottom of the pan, and a gap is positively provided between the bottom surface of the pan 12 and the heating plate 51. There is. With such a configuration, the sensor 50 is less likely to be affected by the heat of the heating plate 51 and the sensitivity is lowered,
When the thickness of the pot 12 is made relatively thick to increase the heat capacity, the temperature of the object to be cooked and the heat-sensitive temperature of the sensor 50 are close to each other, so that heater control is ideal.

The electric rice cooker of the embodiment is as described above, and the cord 17 is pulled out by grasping the plug 17 exposed from the cord outlet 16. As is well known, the cord reel 18 applies a spring force in a direction in which the cord is pulled back by a built-in spring, and when the pulling out of the cord is stopped, the cord is restrained at that position.

When the cord is unconstrained, the cord is automatically wound by the spring force.

[Advantages of the Invention] As described above, according to this invention, the cord reel is interposed between the inner surface of the body member and the outer hook to be fixed to the body member. There is no need to set up a place. Further, since the cord reel is hidden inside the body member, the appearance is good. Also, since the cord reel is composed of the winding section and its holder, it can be attached without changing the structure of the winding section as an off-the-shelf product, and the holder can block the thermal effect on the winding section. You can
