Description

[Detailed description of the invention] This invention relates to a cord winding device for electrical equipment.
In particular, the present invention relates to a structure for installing a cord winding device inside a housing of an electrical device.

The drawing shows the embodiment of this idea into an electric cooking machine. In the figure, 1 is the base of the electric cooking machine, on which a raised part 10 for housing the motor and a container 2 for storing food to be processed are placed. The cutter installed in the container 2 is driven by a motor to cut the food.

The casing forming the raised portion 10 of the base is integrally formed with a ceiling wall 10a and four circumferential side walls 10b hanging down from the outer periphery of the ceiling wall 10a, and forms an inverted container shape that opens downward.

Reference numeral 12 designates a bottom plate that covers the open lower surface of the casing, 13 a cap member for accommodating a switch, etc., placed and fixed on the ceiling wall 10a of the casing, and 14 a leg provided on the bottom plate 12.

Reference numeral 30 denotes a take-up reel for winding up the power cord 31, and a central boss portion 30a is rotatably supported by a shaft portion 32a protruding from the reel cover 32.

The reel cover 32 has an annular outer peripheral wall 32b surrounding the outer periphery of the cord storage space 35 between the reel cover 30 and the winding reel 30, and has a cord entry/exit opening 3 at its lower end that opens in the tangential direction.
2c (Figures 3 and 4).

A power cord 3 is attached to the end surface of the boss portion 30a of the winding rule 30.
1, and the reel cover 32 opposite thereto has a conductive ring 34 connected to the motor and the switch, and both are in rotatable contact.

The take-up rule 30 faces outside through an opening 15 provided in the circumferential wall 10b of the raised portion 10 on the side opposite to the container 2, and has an operating knob 30b protruding therefrom.

Reference numeral 16.16a denotes a hanging part formed downward on the ceiling wall 10a of the raised part, and consists of a box-shaped rib 16 that opens downward and a rib 16a that protrudes inside surrounded by the rib. By inserting the plate-like protrusion 32d formed at the upper end of the reel cover 32 into the box-shaped rib 16, the upper end of the reel cover 32 is held and held so that it does not move in the front and back direction when attached to the electric cooking machine. I can do it.

Further, the plate-like projection 32d is held between the ribs 16 and 16c and does not move in the left-right direction.

The lower end of the reel cover 32 has a boss 3 protruding from the lower end.
By fixing it to 2e with the screw 1T inserted from the bottom plate 12, it can be fixed against movement in all directions including the vertical direction.

18 (Fig. 3) is a pair of ribs protruding from the bottom plate 12, and by inserting a protrusion 32f formed at the lower end of the reel cover 32, the boss 32e and the hole in the bottom plate 12 face each other when tightening screws. Position it accordingly.

Instead of the screws 17 that fix the lower end of the reel cover 32, a rib 19 having an L-shaped end surface 19a that comes into contact with the lower end and side surface of the reel cover 32 is provided on the bottom plate 12, as shown in FIGS. and thereby reel cover 3
2. The vertical and horizontal movements of the lower end can be fixed.

To assemble one unit consisting of the take-up reel 30 and reel cover 32, as shown in FIG. The unit is fixed at step 19, but conventionally, the upper end of the unit is completely free before attaching the bottom plate 12, and the bottom plate 12 is attached while checking the engagement state between the reel cover 32 and the ribs 19. As a result, the unit may fall inward of the base protrusion 10, and the screws 1γ and ribs 19 may fall down as well as the cover 3.
20 has the drawback that it does not correspond to the predetermined position, making assembly difficult.

This idea eliminates the above-mentioned drawbacks, and it is shown in the figure that 36
1 is a cord inlet/outlet body which has a cylindrical shape into which the power cord 31 is inserted, and has a flange 36a at the tip and a protrusion 36b protruding at a distance behind the flange 36a.

This cord entrance/exit body 36 is connected to the side wall 1 around the base raised portion 100.
By inserting the cord into the notch 10c provided at the lower end of the cord and sandwiching the peripheral edge of the notch between the flange 36a and the protrusion 36b, it is positioned against the peripheral side wall 10b and is connected to the inner opening end of the cord entrance/exit body. The cord entry/exit opening 32c of the reel cover is opposed to the cord entry/exit opening 32c.

At the same time, a protruding piece 36c protruding from the inner end of the cord entrance/exit body 36
As shown in FIG. 4, it comes into contact with the inner side surface of the base protrusion of the reel cover 32, and the lower end of the reel cover 32 is sandwiched between the circumferential wall 10b and the projecting piece 36c.

Furthermore, by attaching the cord entrance/exit body 36 to the bottom plate 12, it is held between the circumferential wall 10b and the bottom plate 12, and does not fall out from the notch 10c.

Therefore, as shown in Figure 1, inside the inverted base,
After inserting the unit consisting of the take-up reel 30 and the reel cover 32 and hooking the protrusion 32d to the slot 716, when the cord inlet/outlet body 36 is attached to the notch 10c, the protrusion 36
c holds the unit along the inner surface of the circumferential wall 10b.

As a result, the unit is prevented from falling inward of the raised portion of the base, and by attaching the bottom plate 12, the unit can be reliably fixed within the base.

As described above, this invention is based on the idea that when a take-up reel and a reel cover are assembled into an inverted case, the upper end of the reel cover is hung and held on the ceiling wall of the case, and the reel cover has an opening for cord entry and exit. A protruding piece is provided on the cord inlet/outlet body mounted on the peripheral side wall of the casing opposite to the casing, and the lower end of the reel cover is sandwiched between the protruding piece and the peripheral side wall of the casing. Before attaching the bottom plate to the open bottom surface, you can position the reel cover while visually checking the lower end of the reel cover using the protrusion on the cord inlet/outlet body, and when attaching the bottom plate, you can easily assemble the reel cover without having to worry about it falling over. It has become possible to accomplish this.

Furthermore, since the cord inlet/outlet body is used to prevent the door cover from falling down, there is no need to use separate parts, and it is possible to produce a miniature version.
