Abstract

Iron body 1 includes pressing surface 6 having pointed front end portion 6 a and rear end portion 6 b and a concave power receiving portion 14 having power receiving terminals 15 . Stand 16 includes seat 17 here iron body 1 is placed with the front inclined upward, convex power supply portion 18 having electrodes 20, and receiving portion 24 . In a cordless iron with iron body 1 placed on stand 16, rear end portion 6 b is received in receiving portion 24 , power receiving portion 14 and power supply portion 18 are fitted, and power receiving terminals 15 and electrodes 20 are electrically connected. The joint of power receiving terminals 15 and electrodes 20 are positioned ahead of rear end portion 6 b . Therefore, since the area of pressing surface 6 is ensured and thermal capacity is ensured, it is possible to make rear end portion 6 b pointed. Further, it is possible to see rear end portion 6 b.

Claims (24)

1. A cordless iron comprising:

(I) an iron body having a front end portion and a rear end portion arranged along a longitudinal direction, the iron body comprising:

(I-i) a base having a bottom surface;

(I-ii) a pressing surface disposed on the bottom surface of the base , the pressing surface being extensive in the longitudinal direction and having front and rear pointing edges, respectively, at longitudinal ends thereof;

a grip disposed above the base,

(I-iii) a concave power receiving portion located above the base in the rear end portion of the iron body; and

(I-iv) power receiving terminals disposed in the concave power receiving portion; and

(II) a stand having a bottom surface and first and second ends along a reference direction angled from the bottom surface of the stand, the stand comprising:

(II-i) a seat formed in the stand in the reference direction to receive the iron body therein in such a manner that the longitudinal direction of the iron body is in agreement with the reference direction of the stand, and the front pointing edge of the pressing surface of the iron body is situated on a side of the first end of the stand, while the rear pointing edge of the pressing surface of the iron body is situated on a side of the second end of the stand, wherein the seat is configured to receive the iron body in a position inclined along the reference direction such that the front end portion of the iron body is situated vertically higher than the rear end portion thereof;

(II-ii) a convex power supply portion located on the side of the second end of the stand;

(II-iii) electrodes disposed in the convex power supply portion, wherein when the iron body is positioned in the seat, the electrodes are in electrical contact with the power receiving terminals at locations that are projectable perpendicularly onto the base between the front and rear pointing edges of the pressing surface;

(II-iv) a receiving portion having an upper wall disposed under the convex power supply portion and sloped downwardly towards the second end of the stand to form a receiving space over the seat on the side of the second end of the stand, the receiving space being configured to receive the rear pointing edge of the pressing surface when the iron body is positioned in the seat;

(II-v) a pair of guides running, respectively, in opposite surfaces of the seat in the reference direction towards the second end of the stand and terminating with a space present between respective terminal ends of the guides and the convex power supply portion, wherein the guides function to guide the iron body towards the convex power supply portion when the iron body is being positioned in the seat; and

(II-vi) heat dissipating portions configured to form air channels on the opposite surfaces of the seat on both sides of the convex power supply portion, the air channels being opened, respectively, at the spaces between the terminal ends of the guides and the convex power supply portion, wherein when the iron body is positioned in the seat, the heat dissipating portions function to discharge heat in the receiving portion.

2. The cordless iron of claim 1 , wherein the receiving portion of the stand is sloped downwardly towards the second end of the stand.

3. The cordless iron of claim 1 , wherein the iron body has side surfaces converging towards the rear end portion of the iron body and terminating at the concave power receiving portion.

4. The cordless iron of claim 1 , wherein the iron body comprises a cover having a sloped surface above the base, the sloped surface being extensive in the longitudinal direction continuously from the concave power receiving portion and sloped downwardly, while getting narrower in a lateral direction, towards the rear pointing edge of the pressing surface.

5. The cordless iron of claim 4 , wherein the cover has an terminal end as extensive in the longitudinal direction as the rear pointing edge of the pressing surface.

6. The cordless iron of claim 4 , wherein the cover is formed with an insulating plate surrounding the iron body.

7. The cordless iron of claim 1 , wherein the heat dissipating portions are configured to communicate with the receiving portion on both sides of the convex power supply portion.

8. The cordless iron of claim 1 , wherein the upper wall of the receiving portion is made in part with a protection body at a location of the upper wall where the rear pointing edge of the pressing surface is prone to come in contact with the upper wall when the iron body is being pulled off the seat

wherein.

9. The cordless iron of claim 1 , wherein the upper wall of the receiving portion is more sloped downwardly than the pressing surface of the iron body sloped downwardly in the seat when the iron body is positioned in the stand.

10. The cordless iron of claim 1 , wherein the convex power supply portion further comprises a bulged portion that protrudes in an arc shape toward the first end of the stand.
