Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an iron with a cord reel for general household use.

Conventional Structures and Problems There are generally two types of cord reel devices: one in which the cord is manually reeled in, and the other in which the cord is reeled in using the biasing force of a spring device such as a mainspring. The latter type, which automatically retracts, is preferred in terms of ease of use.

However, in small appliances such as irons, it is necessary to compactly accommodate a cord of about 2 m and reduce the size of the appliance. A pre-winding operation is essential to apply a biasing force to the drum using a spring device. In this case, since the cord is already attached to the drum, the plug connected to the cord gets in the way when either the cord case or the drum is rotated, and the cord is wrapped around the drum. It is necessary to perform pre-winding without maintaining the winding speed, which has disadvantages such as poor workability, easy winding load variation, and unstable winding performance.

Purpose of the Invention In order to solve the above-mentioned conventional drawbacks, the present invention has a drum shape that makes it easy to pre-wind the cord by applying winding force to the cord using a spring device, thereby improving assembly workability and making it easier to wind the cord. To provide an iron with a cord reel that reduces load fluctuation and has stable quality.

In order to achieve the objects described in "Structure of the Invention", the present invention comprises a base having a heater, a handle extending above the base, and a cord reel device for winding a cord. A cord case with a cord outlet provided in a part of the cord case, a drum around which the cord is wound inside the cord case, a mechanism for applying rotational force to the drum in one direction, and an Ail record. It consists of an electrical connection device for the heater and the cord, a locking device for regulating the rotational force of the prepacking drum, and a winding button linked to the locking device, and the cord case is made up of a plurality of members. By forming one or more four sections on the side wall of the take-up drum, assembly workability is improved and cord winding performance is stabilized.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In the figure, 1 is a base having a heater 2, 3 is a cover attached to the base 1, 4 is a handle attached to the cover 3, and a detachable tank 5 is provided in front of the handle. lAL: A cord reel device attached to the stepped portion of the handle 4, which also serves as a support surface when the iron is placed in a free-standing state.

The above-mentioned cord reel device 6 has a cord case 9 which accommodates the cord 7 and forms an outlet 8 for the cord 7 in a part thereof, and a cord case 1° made of a partially transparent material. The cord 7 and the heater 2 are connected to a drum 11.12 provided in the octopus cord cases 9, 10 for winding the cord 7, and a spring device 13 such as a mainspring that gives rotational force in one direction to the drum 11.12. Has a connection stop. It is preferable that the cord be of a rubber insulated structure with high heat resistance and bending resistance, so that it can withstand repeated operations of pulling out and wrapping over a long period of time. The cord 7 has a plug 14 at its tip protruding from the outlet 8. Figure 3.

As shown in FIG. 4, this outlet 8 faces diagonally upward from the side and restricts the direction in which the plug protrudes.Furthermore, due to this restriction, the height at which the plug protrudes is lower than the grip portion 42 of the handle. Therefore, when the cord 7 is stored, it does not get in the way when you hold the iron in your hand, and the height of the packaging box can be made compact and the same as that of a conventional iron. Furthermore, this cord 7 can be drawn out to a length of about 2 m, and in order to be compactly accommodated in the space 15 created by the cord cases 9 and 10, it is arranged in three or four double rows, for example, on the drum 11. I can pray to you on the 12th. Reference numerals 16 and 17 are a small electrode plate and a large electrode plate fixed to the drum 11, and are connected to one end of the cord by welding or the like. Since the small electrode plate 16 and the electrode plate 17 are constantly in contact with the sliding brushes 20, 21 attached to the cord case 9, the contact surfaces must not be roughened by the cord connection. Therefore, each electrode plate has legs 18, 19 for connection with the cord 7, as shown in FIGS. The legs 18 of the small electrode plate 16 face inward of the ring, and the legs 19 of the large electrode plate 1 face outward, so the size of the electrode plate is set to the minimum outer diameter to maintain the insulation distance between the plates. The diameter is sufficient. For example, if the legs 18 of the small electrode plate 16 were to be directed outward from the ring, this configuration would be the best to minimize the size since the large electrode plate would have to have a large diameter to maintain the insulation distance. Furthermore, the foot 18 is located on the through hole 23 of the rotating shaft 22 of the drum 11.12 when the small electrode plate 16 is placed on the drum 12. By welding the end of the cord 7 to this leg 18 and then bending it in a small direction, the through hole 2
3, it is possible to downsize the electrode plate. Furthermore, when welding the cord 7, this leg 18 is connected to the rotating shaft 22.
Since the direction is perpendicular to the direction, the direction of movement of the electric welding electrode becomes the axial direction, which allows for simple movement. To attach the electrode plates 16 and 17 to this drum, connect the cord 7 and then set the cord 7 along the inner wall of the drum 11.
The positioning of the drum 12 is matched to the positioning 24 of the drum 11, and the drum 12 is connected by screws 26 to form an integrated drum. This positioning 24, 25 is such that the shaft 12a of the drum 12 fits into the through hole 23 of the drum 11 by a few millimeters and then starts to fit later, as shown in FIG. By doing so, the fitting of the positioning parts 24 and 25 can be easily done by first fitting the shaft 12a and rotating the drums 11 and 12 around this. Since all you have to do is decide, assembly is much simpler than when fitting two places at the same time. The sliding bluffs 20 and 21 provided in the cord case 9 are each biased by a spring toward the electrode plate side and are in constant contact with each other.
The lead wire 27 is connected to the handle 4 side and connected to the heater 2 via the lead plate 28, and the boss 9d is crushed by ultrasonic welding and attached to the cord case 9.

As shown in FIG. 8, the lead wire attaching portion 29 of the cord case 9 has a slope 9b in the direction in which the lead wire is pulled out so that the sliding brush 20.21 and the lead wire 2.degree. can be easily welded together. This allows the lead wires 27 to be placed on the sliding brushes 20 and 21 without any gaps, making welding easier. The same effect can be obtained by bending the ends of the sliding brushes 20.21 as shown in FIG. 9 instead of creating the large slope 9a, but the machining of the sliding brushes 20.21 will be increased and the boss 9a will have to be bent. When crushing by ultrasonic welding, there is a risk that the bent part will break because it cannot withstand the ultrasonic imaging. Therefore, a better method is to improve the ease of assembly by using the slope 9b.

The spring device 13 has a spiral shape, and its inner and outer ends are engaged with the cord case 1o and the drum 12 to apply rotational force to the drum 12 in one direction. and drum 1
A recess 3o about the diameter of the cord is formed in the side wall 11a of the drum 11 connected to the drum 2. code case 9,1
0 is the cord 7 wound around the drum 11.12, the spring device 13, the large and small electrode plates 16.17, and the sliding bracket 20°21.
It is provided with a pair of members so as to surround the drum rotation shaft 2.
2 and the rotating shaft 31 are connected to each other by screws 32 or the like. This drum rotating shaft 22 is fitted with the shaft 12a with a very small gap so that it can freely rotate smoothly.

On the other hand, since the rotating shaft 31 has a diameter smaller than that of the drum rotating shaft 22, the center deviation with respect to the drum rotating shaft 22 and the error in diameter do not affect the smooth rotation of the shaft 12a. The code case 10 shown in FIG.
As shown in the figure, a window 33 made of transparent resin and a frame 34 made of opaque resin
The window 33 is formed by two-color molding of the drum 11.
The cord 7 wound around the cord 12 occupies most of both side surfaces of the cord case 10 so that it can be seen from the side.

Since the frame 34 and the window 33 are integrated in this way, a complicated structure for mounting the window is not required, the number of parts is small, and the assembly work can be performed simply. Reference numeral 35 designates a screw that connects the cord cases 9 and 1o above each other, and together with the screw 32 constitutes the cord reel device 6 as a unit. It is tightened from the cord case 9 side. Reference numeral 36 denotes a plurality of collars provided on the inner circumferential wall of the drum 11.
Regulates the rotation of 1. 39il-i This lock fitting 38
This is a winding button with a suppressing part 40 provided opposite to one end, and is constantly urged by a spring 41 in a direction away from the lock fitting 38, and by suppressing the lock fitting 38 against the urging force. Remove drum 11 from stopper 36
．． 12 can be rotated.

This winding button 39 is provided near the cord outlet 1 on three sides of the lock fitting 38 attached to the cord case 9, and is flush with the surface of the handle 4 to prevent it from being accidentally pressed during the iron 1 operation. is somewhat low and concave.

Note that there is a hole above the lock fitting 38 for attaching a winding button 39, so the lock fitting 38 is attached to the cord case 9 through this hole.

The operation of the cord case i/j iron of the present invention constructed as described above will be explained.

When the iron is not in use, as shown in FIG.
stands out from When pulling out cord 7, plug 1
4 and pull it in the direction of the arrow to release the spring device 13.
The drum 11. 12 rotates in the direction of the arrow.

At this time, the coat 7 may be completely pulled out, and if the pulling is interrupted at an appropriate length, one of the plurality of stoppers 36 will be caught by the lock fitting 38 and kept in the pulled out state. Therefore, the length of the cord 7 pulled out from the cord reel device 6 can be freely adjusted.

When storing the cord, the take-up button 31 can be pressed. That is, since the drums 11 and 12 are always given a rotational force in the opposite direction of the arrows by the spring device 13, the lock fitting 41 pushed by the suppressing part 40 moves in the two directions of the arrows. When disengaged from the drum 11.
The drum 12 rotates in the opposite direction to the direction of the arrow as described above, and the drums 11.about.12i--y can be housed while being wound in double rows. In the present invention, as described above, the recess 30 having a diameter equal to or larger than the cord 7 is provided in the side wall of the drum 12. This is because it is necessary to wind the mainspring of the spring device 13 several times in advance in the direction C in Fig. 11 so that the cord 7 can be reliably wound even when only a small amount is pulled out. This is to take the code out of the code case 10. Code case 1 as shown in Figure 11
o is a drum 11. It is only slightly larger than the diameter when cord 7 is wound around cord 12. Moreover, the diameter of the side wall of the drum 12 is such that when the cord 7 is wound up, the cord case 11.12 and the cord 7 do not come into contact with each other inside the drum 11. The diameter is approximately the same as when cord 7 is wound around cord 12. For this reason, if you pre-roll, add 1
4 must be taken out of code case 1o.

However, as shown by the broken line in FIG. 11, if the drum side wall shape is circular as in the conventional case, the cord case 10 has a size equal to the diameter of the drum side wall plus the diameter of the cord. However, by partially providing this concave portion 3o and sandwiching the cord 7 in this concave portion 30, the gap between the cord case 1o and the drum 11 becomes unnecessary, so the cord case 10 can be made smaller, and the cord 7 can be connected to the original cord 7 on the side wall of the drum. The purpose of avoiding contact with Cases 9 and 10 remains intact. Also code 7
Since the cords are irregularly wound around the drums 11 and 12, they may not be wound evenly and may overlap in the same area.
5 has the cord 7 double-rowed to minimize its size in order to be compact, so when the cord γ is wound in multiple rows, the winding diameter of the cord 7 becomes large. A situation occurs in which the cord comes into contact with the inner surface of the cord cases 9 and 10 and stops midway through winding. In order to solve this situation, it is possible to make the cord case itself sufficiently large, but as mentioned above, the operability of small appliances such as irons that can be moved freely by hand is significantly impaired. , the code case must be made as small as possible to resolve this.

Furthermore, in the present invention, as described above, one cord case 1o is made of a transparent material and an opaque material, and a window is provided on the side of the cord case 1o so that the cord 7 wound around the drum 11, 12 can be seen from the outside. It is formed. Therefore, even if double winding occurs as described above, it can be easily confirmed through this window 33 that there is no malfunction, and moreover, it can be completely contained by pulling out the cord 7 and winding it again. As a result, it is possible to realize a cord reel that is more compact than conventional concepts. Furthermore, the cord 7 wound around the drum is placed in the cord case 9.
Most of the space is surrounded by 10, so not only fine lint and fluff generated during storage and ironing do not get inside, and electrical failure can be prevented. In addition to improving usability and reducing the effort required when storing cords, it also improves operability when ironing. Furthermore, since the cord case 1° is transparent, a transparent window can be constructed without adding any new parts, which is very rational and does not impair assemblability.

Effects of the Invention According to the present invention configured as described above, the pre-winding operation of the cord reel device when assembling the iron can be greatly improved by allowing the plug to escape to the outside of the cord case, and furthermore, the pre-winding operation of the cord reel device during iron assembly can be greatly improved. When storing the cord, it is very easy to store it by simply pressing the winding button, and the cord case provided at the back of the clap is also compact enough to accommodate the cord, making it easy to operate when ironing. Become something.
