## Background
This application is a 371 application of PCT/JP2010/006275 having an international filing date of Oct. 22, 2010, which claims priority to JP2009-252604 filed Nov. 4, 2009, the entire contents of which are incorporated herein by reference.
TECHNICAL FIELD
The present invention relates to an iron that smoothes out wrinkles in clothing, particularly, a cordless iron of which the iron body has no cord.
BACKGROUND ART
Ironing has an operation of smoothing out wrinkles by moving an iron on clothing and an operation of arranging the shape of the clothing with the iron in place. Ironing is performed by alternately repeating the operation of smoothing out wrinkles and the operation of arranging the shape of the clothing.
In order to make the ironing operation easier, there is a cordless iron of which the iron body has no power cord (for example, PTL 1). The cordless iron includes a stand with a power cord and an iron body equipped with a heater for heating the pressing surface. When the iron body is placed on the stand, the power cord of the stand and the heater of the iron body are electrically connected. That is, the heater is supplied with power only when the iron body is placed on the stand. A user separates the iron body with the pressing surface heated by the heater from the stand and performs ironing, using the remaining heat of the pressing surface. The temperature of the pressing surface gradually decreases during ironing. However, the user occasionally places back the iron body onto the stand to arrange the shape of clothing. In this state, the heater is supplied with power again and the pressing surface is heated. It is possible to perform ironing in the same way as the iron with a power cord, with the cordless iron, by performing the operation described above.
As described above, placing the iron body onto the stand is frequently performed during ironing. When the iron body is placed on the stand, the power receiving portion of the iron body and the power supply portion of the stand are fitted to each other. Accordingly, power receiving terminals of the power receiving portion and electrodes of the power supply portion are electrically connected to each other. However, when the iron body is carelessly placed on the stand, the electric connection is not reliably achieved. Further, carefully placing the iron body onto the stand in order to achieve reliable electric connection was troublesome for the user.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
First Exemplary Embodiment
FIG. 1 is a side view of cordless iron 1 according to a first embodiment of the present invention. FIG. 2 is a partial cross-sectional view of the cordless iron. FIG. 3 is a cross-sectional view showing main parts of the cordless iron. FIG. 4 is a top view of an iron body of the cordless iron. FIG. 5 is a rear view of the iron body of the cordless iron. FIG. 6 is a top view of the cordless iron. FIG. 7 is a top view of a stand for the cordless iron. FIG. 8 is a top view showing main parts of the stand for the cordless iron.
Iron body 1 of a cordless iron includes base 3 that is heated by embedded heater 2. Pressing surface 6 is disposed on the bottom of base 3. Front end portion 6a and rear end portion 6b of pressing surface 6 are pointed. Concave vaporizing chamber 4 is formed on the top of base 3. Tank 7 made of resin stores water that is the basis of steam. The water is supplied and blocked to vaporizing chamber 4 from tank 7 by operating steam button 8. Steam generated in vaporizing chamber 4 is ejected from steam hole 5 formed through pressing surface 6. Steam hole 5 is formed across a wide range of pressing surface 6, including the peripheries of front end portion 6a and rear end portion 6b. Further, the top of base 3 is covered by insulating plate 9. Grip 10 made of resin is disposed above base 3, that is, insulating plate 9.
Terminal portion 13 is disposed at rear portion of iron body 1. Grip 10 is equipped with a grip backplate 12 to cover terminal portion 13 from behind. Accordingly, power receiving portion 14 shaped by recessing the rear surface of iron body 1 inward is formed. Power receiving terminals 15 electrically connected with heater 2 are disposed protruding toward the rear of iron body 1, in power receiving portion 14.
Iron body 1 is placed on stand 16. Seat 17 having support bodies 17a is disposed in stand 16. Pressing surface 6 of base 3 of iron body 1 is supported from below by support bodies 17a, which are composed of rollers. Iron body 1 is placed with the front inclining upward at 20 to 30°. The inclination angle allows a user to easily place and separate iron body 1.
As shown in FIG. 7, support bodies 17a are disposed at two positions in the front-rear direction and support pressing surface 6 at position spaced in the front-rear direction. Further, when iron body 1 is placed on seat 17, iron body 1 is naturally moved back by the rollers of support bodies 17a. Accordingly, iron body 1 is stably supported on stand 16.
Convex power supply portion 18 fitted in power receiving portion 14 of the placed iron body 1 is formed at the rear portion of stand 16, that is, the rear portion of seat 17. Holes 19 in which power receiving terminals 15 are inserted when iron body 1 is placed are formed through the front of power supply portion 18. One hole 19 is formed at each of the left and right of power supply portion 18. Power receiving terminals 15 inserted from holes 19 are electrically connected to electrodes 20 disposed in power supply portion 18.
Shutter 21 that is pushed by a spring (not shown) to close holes 19 is disposed in power supply portion 18. Holes 19 are closed by shutter 21, when iron body 1 is separated from stand 16. When iron body 1 is seated on stand 16, support portion 22 disposed at power receiving portion 14 presses backward an operating portion 21a of shutter 21. Accordingly, support portion 22 turns shutter 21 against the pushing force of the spring and holes 19 are opened. As holes 19 are opened, power receiving terminals 15 are inserted and electrically connected with electrodes 20.
Support portion 22 is disposed at the upper portion in power receiving portion 14, above power receiving terminals 15. Support portion 22 is integrally formed with grip backplate 12 in a thin plate shape, vertically and protruding backward from iron body 1.
Slit 23 which is a groove where support portion 22 is fitted is formed on the top of power supply portion 18. Slit 23 is formed in the movement direction of iron body 1, that is, in the front-rear direction. Therefore, when iron body 1 is placed on stand 16, the position of iron body 1 is restricted to the left and right, such that iron body 1 is stable.
Guide portion 18a inclining left and right and forward from the front end portion of slit 23 is formed at the inlet of slit 23, that is, at the front of power supply portion 18. Guide portion 18a is formed substantially in a V-shape with inclining surfaces. By the shape, when iron body 1 is placed on stand 16, the front end of support portion 22 slides on the inclining surfaces toward the inlet at the front end portion of slit 23, in contact with the inclining surfaces of guide portion 18a. Therefore, support portion 22 is guided to slit 23.
Bulged portion 18b protruding in an arc shape toward power receiving portion 14 when iron body 1 is placed is formed at the lower portion of the front of power supply portion 18, that is, under guide portion 18a. When iron body 1 is placed on stand 16, opening end 14a of power receiving portion 14 slides left and right along the arc surface, in contact with bulged portion 18b. Therefore, power receiving portion 14 is guided to power supply portion 18. Guide portion 18a is positioned above holes 19. Bulged portion 18b is positioned under holes 19.
Accordingly, when iron body 1 is placed on stand 16, power supply portion 18 of stand 16 is reliably fitted in power receiving portion 14 of iron body 1 by guide portion 18a disposed at the upper portion of power supply portion 18 and bulged portion 18b disposed at the lower portion. That is, the positional deviation at an angle to the left and right of power receiving portion 14 is corrected. Accordingly, power receiving terminals 15 and electrodes 20 are reliably electrically connected.
Receiving portion 24 that receives rear end portion 6b of pressing surface 6 of base 3 where iron body 1 is placed is disposed under power supply portion 18. The joint of power receiving terminals 15 and electrodes 20 is positioned forward by rear end portion 6b, with rear end portion 6b positioned in receiving portion 24. That is, the front ends of power receiving terminals 15 are positioned ahead of rear end portion 6b, when iron body 1 is placed on stand 16.
Receiving portion 24 is formed with the top of seat 17 tapered rearward. Accordingly, pointed rear end portion 6b is received in a compact size under power supply portion 18. Further, iron body 1 is also formed with a side 10a of grip 10 tapered toward open end 14a of power receiving portion 14.
Cover 25 that covers the top of rear end portion 6b is disposed under power receiving terminals 15. Cover 25 is formed by extending downward grip backplate 12 where power receiving portion 14 is formed. That is, cover 25 forms a portion of grip 10. The outer edge of cover 25 is formed along the outer edge of base 3. That is, cover 25 covers the upper portion of rear end portion 6b, substantially in the same shape as rear end portion 6b. 
Heat dissipating portions 26 are formed at both sides of power supply portion 18, at the rear portion of stand 16. Heat dissipating portions 26 communicate with both sides of power supply portion 18 through receiving portion 24. When iron body 1 is placed on stand 16, rear end portion 6b is positioned in receiving portion 24. Rear end portion 6b is heated at a high temperature together with the entire pressing surface 6. Heat of rear end portion 6b is discharged outside from receiving portion 24 by heat dissipating portion 26, such that abnormal overheating of power supply portion 18 is suppressed.
Guides 27 are formed at both sides of seat 17. The gap between guides 27 at both sides decreases toward power supply portion 18. Heat dissipating portion 26 is formed between rear ends 27a of guides 27 and power supply portion 18. Accordingly, heat dissipating portion 26 has a sufficient heat dissipation space. Iron body 1 is placed on stand 16, as side 10a of grip 10 is guided by guides 27. Accordingly, power receiving portion 14 of iron body 1 is reliably guided to power supply portion 18 of stand 16.
Receiving portion-upper wall 18c forming the top of receiving portion 24 is formed to incline upward toward the front of stand 16. The rear portion of receiving portion-upper wall 18c extends behind rear end portion 6b such that rear end portion 6b is received in receiving portion 24. Rib 25a protruding in an arc shape toward receiving portion-upper wall 18c of receiving portion 24 is disposed on cover 25 of iron body 1. When iron body 1 is placed onto or separated from stand 16, the top of rib 25a moves in contact with receiving portion-upper wall 18c. Accordingly, iron body 1 is smoothly attached/detached.
Next, the movement and operation of the cordless iron of the embodiment are described. First, a user places iron body 1 onto seat 17 of stand 16. That is, when pressing surface 6 is placed on support bodies 17a, power receiving terminals 15 electrically connected to electrodes 20. Accordingly, electricity is supplied to electrodes 20 through power cord 28.
The temperature of pressing surface 6 is set by a temperature setting unit 29 disposed at grip 10. Heater 2 heats base 3 such that pressing surface 6 reaches a set temperature (for example, 200° C.). As base 3 is heated, vaporizing chamber 4 is also heated. When the temperature of vaporizing chamber 4 reaches the vaporization temperature of water, bimetal 30 turns around and heat-responsive valve 31 opens. In this state, when steam button 8 is pushed, the water stored in tank 7 drops into vaporizing chamber 4. The water dropping in the vaporizing chamber 4 vaporizes into steam and discharged from steam hole 5 formed through the pressing surface 6.
Receiving portion 24 that receives rear end portion 6b of iron body 1 is disposed under power supply portion 18. By this configuration, when iron body 1 is placed on stand 16, the joint of power receiving terminals 15 and electrodes 20 is positioned ahead of rear end portion 6b. That is, pressing surface 6 extends to the rear end of iron body 1. Accordingly, it is possible to make rear end portion 6b pointed without largely reducing the area of pressing surface 6. Since it is possible to ensure the area of pressing surface 6, as described above, it is possible to ensure thermal capacity of pressing surface 6. That is, it is possible to make rear end portion 6b pointed, for a cordless iron using remaining heat. Therefore, in ironing that uses steam, a decrease in temperature of pressing surface 6 is suppressed, such that a cordless iron that is convenient to use is achieved.
A user separates iron body 1 from stand 16, with grip 10 in a hand, for ironing. Further, the user moves forward and backward iron body 1 while pressing down clothing. When iron body 1 moves forward, the clothing is pressed and wrinkles of the clothing are smoothed out by pointed front end portion 6a. Further, as shown in FIG. 4, rear end portion 6b has a pointed shape, the same as front end portion 6a. Therefore, even though iron body 1 moves back, similar to the forward movement, the clothing is pressed and wrinkles of the clothing are smoothed out. Accordingly, return creases are not made. That is, similar to the forward movement of iron body 1, it is possible to move iron body 1 in the direction of rear end portion 6b, which makes ironing easy.
Rear end portion 6b protrudes rearward further than the rear ends of power receiving terminals 15. Accordingly, it is possible to see rear end portion 6b even though iron body 1 moves back. That is, similar to front end portion 6a when iron body 1 moves forward, it is possible to see rear end portion 6b even during backward movement, such that ironing can be efficiently performed in the front-rear direction.
It is possible to move forward iron body 1, with rear end portion 6b at the front, when holding iron body 1 with the other hand. That is, it is not necessary to change the direction of iron body 1 when holding iron body 1 with the other hand.
Further, side 10a of grip 10 is tapered toward open end 14a of power receiving portion 14. Therefore, rear end portion 6b is reliably seen, not only in backward ironing, but in forward movement with rear end portion 6b at the front. That is, usability when moving iron body 1 in the direction of rear end portion 6b is improved.
Open end 14a of power receiving portion 14 is positioned around rear end portion 6b. Therefore, open end 14a is necessarily small. Power supply portion 18 where open end 14a is fitted from outside is also formed small in the left-right direction.
In the embodiment, guide portion 18a and bulged portion 18b that guide power receiving portion 14 to power supply portion 18 are disposed at the front of power supply portion 18. Slit 23 where support portion 22 is fitted is disposed at the center of the top of power supply portion 18. Support portion 22 that is fitted into slit 23 and rib 25a that comes in contact with receiving portion-upper wall 18c of power supply portion 18 are disposed substantially at the center of power receiving portion 14. Similarly, power supply portion 18 is formed small in the left-right direction and side 10a of grip 10 is tapered toward rear end portion 6b. 
Since receiving portion 24 is tapered toward the rear portion of seat 17, when iron body 1 is placed on stand 16, power receiving portion 14 of iron body 1 is guided and fitted on power supply portion 18. Therefore, electrodes 20 of power supply portion 18 and power receiving terminals 15 of power receiving portion 14 are reliably connected. Since receiving portion 24 is tapered toward the rear portion of seat 17, receiving portion 24 is formed in a compact size at the rear portion of stand 16.
Since cover 25 covering the top of rear end portion 6b is disposed under power receiving terminals 15, heat from rear end portion 6b that is heated at a high temperature is blocked. Abnormal overheating of power supply portion 18 is suppressed by this configuration. Further, by the configuration, when iron body 1 is placed onto and separated from stand 16, it is possible to prevent rear end portion 6b from coming in contact with power supply portion 18.
The outer edge of cover 25 is formed along the outer edge of base 3. By this configuration, it is possible to protect power supply portion 18 and prevent overheating of power supply portion 18 while easily see rear end portion 6b. 
Cover 25 is formed by extending downward power receiving portion 14 that is a portion of grip 10. By this configuration, when iron body 1 is placed on stand 16, cover 25 covers power supply portion 18 from the front. Accordingly, power supply portion 18 is protected and overheating is prevented, even if iron body 1 is frequently placed onto and separated from stand 16 during ironing.
Heat dissipating portions 26 that discharge heat of rear end portion 6b to the outside from receiving portion 24 are formed at both sides of power supply portion 18. By this configuration, the heat of rear end portion 6b is dissipated and overheating of power supply portion 18 is prevented, even if iron body 1 is frequently placed onto stand 16 during ironing.
Heat dissipating portions 26 communicate with both sides of power supply portion 18 through receiving portion 24. By this configuration, the air in receiving portion 24 smoothly flows. That is, efficiency of heat dissipation is improved and the internal temperature of receiving portion 24 is prevented from increasing.
Guides 27 that guide power receiving portion 14 to power supply portion 18 are disposed at both sides of seat 17. Since heat dissipating portion 26 is formed between rear ends 27a of guides 27 and power supply portion 18, the air in receiving portion 24 is efficiently discharged to the outside from the closer distance.
Power supply portion 18 is formed by inclining upward the front of receiving portion-upper wall 18c that is the top of receiving portion 24. By this configuration, it is possible to easily separate iron body 1 from stand 16. The inclination angle of the front of receiving portion-upper wall 18c is larger than the inclination angle of the front of pressing surface 6. Therefore, when iron body 1 is separated from stand 16, even if iron body 1 is separated while being lifted upward, rear end portion 6b does not come in contact with receiving portion-upper wall 18c of power supply portion 18. That is, it becomes easy to attach/detach iron body 1 to/from stand 16.
Bulged portion 18b that protrudes in an arc shape toward power receiving portion 14 is formed at power supply portion 18. By this configuration, even if receiving portion 14 is biased to the left and right, when iron body 1 is placed on stand 16, open end 14a of power receiving portion 14 slides left and right along the arc surface, in contact with bulged portion 18b. Accordingly, iron body 1 is moved to a predetermined position and the position is restricted, such that power receiving portion 14 is reliably fitted on power supply portion 18.
Support portion 22 having a plate shape protruding rearward and in the direction perpendicular to the bottom of base 3 is disposed inside power receiving portion 14. Slit 23 which is a groove where the support portion 22 is fitted is disposed on the top of the power supply portion 18. Guide portion 18a inclining toward slit 23 is disposed on the front of power supply portion 18. By this configuration, support portion 22 is fitted in slit 23 and the position of iron body 1 is restricted. Accordingly, iron body 1 is placed at a predetermined position on stand 16 and power receiving terminals 15 and electrodes 20 are reliably connected. Since support portion 22 is fitted with a predetermined length with respect to slit 23, the position of iron body 1 is restricted and it is possible to easily separate iron body 1 from stand 16.
Guide portion 18a inclines forward from slit 23 and is formed substantially in a V-shape to be open left and right. By this configuration, when iron body 1 is placed on stand 16, the front end of support portion 22 is guided to slit 23 while sliding on the inclining surfaces toward the inlet of slit 23, in contact with the inclining surfaces of guide portion 18a. Therefore, support portion 22 is reliably fitted in slit 23.
As described above, iron body 1 is guided inside by guide portion 18a at the upper portion of power supply portion 18 and guided outside by bulged portion 18b at the lower portion of power supply portion 18. That is, iron body 1 is reliably positioned from the upper portion and the lower portion when placed on stand 16, and power receiving terminals 15 and electrodes 20 are reliably connected.
That is, even if iron body 1 is placed on stand 16 with power receiving portion 14 inclining in the left-right direction, support portion 22 is in contact with inclining guide portion 18a and the upper portion of power receiving portion 14 is guided inside. Further, even if iron body 1 is placed on stand 16 with power receiving portion 14 biased in the left-right direction, bulged portion 18b is in contact with power receiving portion 14 and the lower portion of power receiving portion 14 is guided outside. Accordingly, even if iron body 1 is placed on stand 16 carelessly, inclination or deviation in the left-right direction is corrected to the correct position by guide portion 18a and bulged portion 18b. Accordingly, usability of the cordless iron is improved.
Second Exemplary Embodiment
FIG. 9 is a partial cross-sectional view of a cordless iron according to a second embodiment of the present invention. The cordless iron of the embodiment is different from the first embodiment in that cover 25 covering the top of rear end portion 6b is implemented by insulating plate 90 covering the top of base 3. The other configurations are the same as those of the first embodiment.
According to the configuration of the embodiment, it is possible to cover the top from front end portion 6a to rear end portion 6b with insulating plate 90, without a gap. Therefore, it is possible to improve insulating effect of base 3 and simplify the configuration.
Third Exemplary Embodiment
FIG. 10 is a partial cross-sectional view of a cordless iron according to a third embodiment of the present invention. The cordless iron of the embodiment is different from the first embodiment in that protection body 32 is disposed on receiving portion-upper wall 18c of power supply portion 18 that forms the top of receiving portion 24. The other configurations are the same as those of the first embodiment.
Protection body 32 is made of thermally-resistant rubber. When iron body 1 is separated from stand 16, rear end portion 6b is prevented from coming in contact with receiving portion-upper wall 18c of power supply portion 18 by protection body 32.
When iron body 1 is placed on stand 16, power receiving terminals 15 are connected with electrodes 20 through holes 19 of power supply portion 18. Support portion 22 is fitted in slit 23 of power supply portion 18. When iron body 1 is separated, power receiving terminals 15 are separated from holes 19 and support portion 22 is separated from slit 23. In this process, the position of iron body 1 is not restricted with respect to stand 16.
Since the positional restriction is removed, rear end portion 6b easily comes in contact with receiving portion-upper wall 18c of power supply portion 18, in receiving portion 24. Protection body 32 prevents rear end portion 6b and receiving portion-upper wall 18c from coming in contact with each other. Therefore, it is effective to dispose protection body 32 at the upper portion of receiving portion-upper wall 18c where rear end portion 6b and receiving portion-upper wall 18c easily come in contact with each other after the position of iron body 1 is not restricted.
According to the configurations described above, shock when iron body 1 is separated is attenuated. Further, it is possible to protect power supply portion 18 from heat and shock.
INDUSTRIAL APPLICABILITY
As described above, the present invention is useful as a cordless iron, because the iron body is placed at the correct position when being placed on the stand.
