Description

[Detailed Description of the Invention] The present invention relates to a structure for attaching a power cord fixing device to an electric appliance.

Conventionally, when attaching a power cord 4 to an electric appliance 1 having a cylindrical outer case 2 as shown in FIG. 1A, the cylindrical outer case 2 as shown in FIG. A power cord fixing tool consisting of an inner and outer two members 3A and 3B, which have a through hole 5 in the middle part of the body 2b and hold a bushing part 4a of a power cord 4 inside the through hole 5. 3 is attached, and a power cord 4 is drawn into the outer case 2 through the through hole 5.

However, when the hole 5 for attaching the power cord fixing device is provided in the middle part of the body 2b, the attachment height of the electric component 6 such as an electric heater must be increased in accordance with the attachment height of the power cord 4. Therefore, a dead space D is created between the bottom of the electrical component 6 and the bottom plate 7 of the outer case 2.

For this reason, there is a problem that the height of the electric appliance 1 itself becomes unnecessarily high, and the cost of materials increases by the height.

On the other hand, in order to improve the above-mentioned problem, the hole for attaching the power cord fixing device is replaced by a through hole provided in the outer case body 2b, and is replaced with a notch opening in the lower peripheral edge 2C of the outer case 2, and the notch is provided with the Attaching the power cord fixing device 3 can reduce the dead space as described above, but on the other hand, if a notch is formed that opens at the bottom end of the outer case, the notch will gradually expand toward its periphery during long-term use. The gap between the notch and the power cord fixture 3 becomes large, resulting in a problem that the power cord fixture 3 becomes loose.

In view of the above-mentioned problems, the present invention provides a notch in which a flange is formed along the opening edge of the lowermost end of the cylindrical case, and the flange is held against the notch from the outside. By installing a power cord fixing device with a lip formed on it, you can prevent the notch from expanding, thereby reducing the cord space that is formed under electrical components such as electric heaters, and also making it easier to connect the power cord to the cylindrical case. The purpose of this invention is to propose a structure for attaching a power cord fixing device to an electric appliance, which enables reliable attachment.

Hereinafter, the present invention will be explained based on the embodiment shown in FIGS. 2 to 6. FIG. 2 shows an electric fryer (hereinafter referred to as fryer) 10 according to the embodiment of the present invention.

Further, the outer member 21 and the inner member 22 can be inserted into and removed from each other, and the cord holder 20 sandwiches the peripheral edge 24 b of the notch 24 between them, and furthermore, the outer member 21 and the inner member 22 are inserted into each other. It is attached to the outer case 11 by connecting them with screws 34.

As shown in FIG. 6, the notch 24 provided in the lower end edge 11a of the outer case 11 cuts a part of the central part of the horizontal elongated hole 25 provided along the lower end surface 11C of the outer case 11. End face 11
It is formed into a roughly T-shape that opens toward C.

Furthermore, the outer case 11 is located at the opening edge 24a of the notch 24.
A bent flange 26 of an appropriate width is formed inwardly.

This flange 26 engages with the cord holder 20 to prevent the notch 24 from expanding in the circumferential direction and to reinforce the notch 24 itself.

In the illustrated embodiment, the flange 26 is formed only at the peripheral edge of the elongated hole 25.

The outer member 21 of the cord holder 20 is composed of a front plate 23 that comes into contact with the outer surface of the cutout peripheral edge 24b of the outer case 11, and a protrusion 29 that projects from the front plate 23.
