将电源线拉出时，平面涡旋簧储能，停止拉出时，转轴在涡旋簧作用下回转至被棘轮机构锁定，电源线停止动作；收线时利用按钮或其他方式，打开锁定机构，使平面涡旋簧的储能释放，带动转轴将电源线缠绕收回。
2. 用途：自动收线机构应用在熨斗和其它家电产品上的主要目的，是在使用完毕後，将电源线收纳起来，便于存放。
3. 适用的电源线：自动收线机构的电源线主要为两线（不带地线）的橡胶线，目前有日本市场JQA 规格的电源线及美国市场UL 规格的电源线，欧洲市场TUV 规格的棉纱线由于受卷线空间及表层抗摩强度的限制，目前尚未有自动收线的应用。
二．收线机构的主要方式1 ．内部机构介绍：下面以7301 为例阐述自动收线装置的内部机构首先由後盖和中介盖板组成收线的空间及中介盖板提供收线的旋转轴。
在旋转轴的前端安装有大、小滑电环。
此两个滑电环的作用是将电源线与熨斗的内配线连通。
在旋转轴上有可以旋转的前、後卷线筒。
在前後卷线筒之间有电源线。
前後卷线筒靠三颗螺钉锁附在一起，同时将电源线压紧。
电源线的两极分别与固定在前卷线筒上的大、小弹片点焊在一起。
大小弹片的端头部各有两银触点与其点焊在一起。
大小弹片可以与前卷线筒一起围绕着旋转轴转动。
大小弹片通过银触点在大小滑电环上滑动，从而使电源线与熨斗的内配线导通。
银触点起的作用是减少磨损，保证良好的接触，防止电路导通时在大小弹片与大小滑电环之间有弧光放电，确保大小弹片不会与大小滑电环因少许的弧光放电就粘焊在一起。
为了进一步减轻银触点的磨损，在银触点与大小滑电环之间涂有节点油。
在後卷线筒的候部安装有收线的平面涡旋簧。
它的一端与後卷线筒相联，另一端与中介盖板上的槽相联。
这样当电源线向外拉出时，涡旋簧就会储能。
在後卷线筒上装有压紧板以防止涡旋簧在上预紧力时会弹出而增加不安全因素。
在前端由按钮、释放弹簧、锁定片、前卷线筒上的棘轮组成收线的释放机构。
当按钮按下时，锁定片会释放前卷线筒上的棘轮机构，使电源线收进。
不按时，电源线停止。
在按钮、锁定片下有复位弹簧。
该收线机构下面有两个螺钉将後盖、中介盖板锁附在一起。
在中介盖板的下部有卡勾机构，可以与隔基卡接。
上部从後面穿过後盖、中介盖板有两个螺钉锁附在固定在本体上的锁定片上。

我们就曾作过在7302单圈卷线机构上加按钮控制，及在78 61卷线机构中取消按钮而采用拉动电源线收线的尝试，但未经量产的验证。
* ii .收线控制机构与限速机构的方式将于下具体阐述* i i i .在多圈收线机构中未见到限速机构的一个可能原因为，多圈收线需要达到一定的速度，以克服更大的收线阻力。
我们发现当速度较慢时，线的分布会严重不均匀而沿一圈迅速爬高，容易卡死。

对与收拉线60 00次，以及电源线弯曲50 000次，在机构上主要应注意入线口的设计。
入线口的上下两侧向内必须是大的圆弧过渡，以免尖锐的过渡会刮伤电源线；另外电源线入口的左右两侧在与上下便过渡处不得出现锐角或凸出在上下两侧上的锐边。

3. 有关专利：在7861的设计过程中，我们曾受到松下专利的困扰，主要的专利限制有两条：I. 按钮控制的收线机构若不用按钮控制，则需采取大同的棘轮机构或三洋的滑动轨道机构，但也可能牵扯到这两家公司的专利问题.II. 底部开口以利收线这个限制条件对收线空间影响非常大，若要底部封口，则必须给定足够的收线空间•（有关松下在美国申请的专利原文，请参照附录一）4. 空间要求（多圈）**UL・舗就3*»14有養#«»立*«•■二斯示氏0110（^34（40.厲就從空间该上⑥豪eO*M«中醴杆童问・MH w*i£A»Ti«*MT0 8.00 関海代植料童凤去•理《HUt不扈与评侵廉虬«»*«*»*»< «AA#f^K«JLA«Ad>KA 曲4 0B4J1000$盾JUI百什/三.JQA规格电源线的自动收线机构1. 电源线规格日本市场两扁插电压：10 0V电源线外露长度：1. 85m2. 安规要求裸露带电体的电气间隙2。

在後盖的前端长出一个有 孔的卷线筒， 电源线从孔中通过， 直接与内配线 相连 。
电源线 卷在卷线筒上。
线卷好後， 将套在卷线筒後部的橡胶套翻过来 护住电源线。
但是经开了一个简易模後， 发现了许多问题而无 法实施。
2．连杆转动 的手 动收线形 式 此种形式结构与自动收线十分相似。
所不同的是它的後卷 线筒後部没有装储能的平面涡旋簧，而是从其後部长出一个轴， 在後盖的後面上有一个连杆， 可以带动整个卷线轮转动。
从而 达到收线的功能。
此种 ■-TS ------------------------------------------------ K J -1------------------------1!_ -丨「 I i (I c 1 i d 寸w 恚底面夕卜附示意匡后矗侧面夕卜形式的缺点是收线要手工操作，而且收线力一旦取消後，卷紧的线会因线的回弹力而松动。
3 ．插头端的自动收线机构此种设想是将收线装置与熨斗分离，而靠近电源线的插头端，类似于收线装置带一插头，而用不带插头的电源线连接收线装置与熨斗，收线後将收线装置挂在熨斗上。

BAC KGROUND OF THE IN VENT IO NEl ect ri cal ly ope r at ed irons are pr ov i ded wi th an electric cord to extend t o apower out l et. It has been known to provi de the rear end of irons wi th means about which the electric cord may be wound for storage pu rp os es. However, this previousl y known means of storing t he el ect ri c cord has not been successful as the cord in e ss en ce is not ret ai ne d in a coiled configur ation. Th ere has also been the need to reduce the overall length of the i ro n in order to ensure stability of the iron when i t rests on i ts rear face so as to have the hot plate generally upwardl y extendi ng. If the rear of the i ron i s extended to accommodate the cord, the iron becomes less stable due to i ts h ei ght when in the rest pos ition.Steam irons are provided with a resevoir into which water is delivered, which water is transformed into steam duri ng the ironi ng p rocess. Frequently new irons are sold with a beaker which may be used to deliver water t o the water inlet of the iron. Th ese b ea k ers are not physically associated with the iron and accordingly become l ost.OBJECT OF TH E INV ENT IONIt is the obj ect of the present invention t o overcome or sub st ant i al ly ameliorate the above disadvantages.SUM MARY O F TH E IN VENT IONThere is di scl osed herein a garment iron compri sing:a main body provi ding a handle and being equi pp ed wi th a sol epl at e, and electrically ope r at ed means to heat the soleplate, said body havi ng a rear face wi th en ga ga bl e means;an elect ri c cord ex t endi n g fr om said body to connect sai d el ect ri cally operated means to an el ect ri c supply; and a cord r eel about whi ch said cord i s wound, said reel having attachment means to r el eas abl y engage said engagable means to selectively secure said reel to said main body.Preferabl y the reel is hollow so as to provi de a cavi ty, and a beaker i s shaped to be received within said cavity.BRIEF DESCRIPTION OF T HE DRAW IN GSA p referred form of the p resent invention will now be described by way of example wi th reference to the accom panying dr awi ngs wh erein:FIG. 1 is a schematic parts expl oded perspective view of an iron i ncorporati ng a cor d reel and beaker;FIG. 2 is a schematic rear el ev at i o n of t he reel of FIG. 1;FIG. 3 is a schematic fr ont elevation of the reel of FIG. 1; FIG. 4 is a schematic t op pl an vi ew of t he reel of FIG. 1; FIG. 5 is a schematic bottom plan view of t he reel of FIG. 1; andFIG. 6 is a schematic sectioned side el evation of the reel as illustrated in FIG. 5 sectioned along the line 6--6. DESCRIPTION OF TH E PREFERRED EMBODIMENT In the accompanyi ng drawi ngs t here i s schematically depictedan iron 10. The iron 10 includes a main body 11 provided with a sol epl ate 12 wh ich is electrically heated. The body 11 is al so pr ov i d ed with a handle 13 and a rear face 14. Th e soleplate 12 is connected to an el ect ri c cord 15, which co nn ect s the sol epl ate 1 2 t o a suppl y of electricity.Adjacent to the rear face 14 is a lip or flange 16, whi ch pr ov i d es an engagable means to be operatively associated wi th a cord reel 17. The cord reel 17 has a forward flange 18 of " L- shaped" configuration so as to have a base 19 and a forwardly projecting lip 20. The flange 20 ex t ends down the left and right hand sides of the reel 17 and isadapted to en gage the flange 16 so that the reel 17 can be mounted adj acent to the face 14. Th efl ange 18 i s particularly co nfi gu red so that the reel 17 i s coupl ed to the flange 16 by downw ard m ov em ent o f the reel 17 over t he rear face 14.The reel 17 has a recess 21 which forms a loop and within which thecord 15 iswound. The rear of the reel 17 is also pr ov i d ed with a fl ange 22 so that the cord 15 has its loops sandwiched between the flanges 18 and 22.Th e reel 17 is of a tri angul ar confi guration wi th its upper apex pr ovided wi th a trough 23 having a f orward aperture 24 whi ch en abl es the cor d 15 to enter the trough 23, and a rearw ard aperture 25 enabling the cord to extend down wardl y from the trough 23 t o a l ow er trough 26. Th e cord 15 passes thro ugh t he trough 26 and t hen is woun d arou nd t he reel 1 7 so t hat the loops are cont ained i n the recess 21.The reel 17 Is of a hol low con fi gu rat i on so as to provide a central chamber 27. Lo catabl e wi thi n the chamber 2 7 i s a beak er 28 which is of a complementary shape to the chamber 27 and includes a recess 29 i nto which the trough 23 proj ects, and a rear recess 30 down which thecord passes to enter the trough 26. Th e beaker 28 may beof a "dish" co n fi gu r at i on so as to have an open face or alternatively may be provided with a filling neck eq ui pp ed with a s top p er. Ho w ev er the preferred construction of the beaker 28 hasafilling aperture 38 which i nhibi ts st orage of the beak er 28 w i th water i n it.Preferably the beaker 28 can "snap" fit within thechamber 27. To secure thereel 17 in position, there is provided a catch 31. The catch 31 isformed integral with the remainder of t he reel 17 and includesa lever 32 terminating at one end with a finger grip portion 33. The finger grip portion is moved in the di recti on of the arrow 34 to cause pi voting of the lever 32 i n the direction of the arrow 35. The forward end of the lever 32 is pr ov i d ed with acatch member 36 having a catch lip 37. Pivoting of the lever 32 in the di rect i on of the arrow 35 causes pivoting of thecatch member 36 in the direction of thearrow 38. The lip 37 engages a lower portion of the fl ange 16 or an abutment especially provided. When the reel 17 is moved down the flange 16, the lip 37 isresiliently deflected rearward until the reel17 has reached itsrest position. Thereafter, t he lip 37;.m oves i nto i ts clip engagement position. To release the reel 17, the user moves the fi nger gri p portion 33 in the direction of the arrow 34. Thisthen pivots the lip 37 from engagement and permits the reel 17 to be moved upward relative to the fl ange 16 until the flange 18 is disengaged t her ef rom. Preferably, the reel 17 is moul ded of pl asti cs m ateri al. The beaker 28 wouldbe also moulded from plasti cs m at er i al.The above described preferred embodi m ent has the advantage of providing a st or age for the cord 15, which storage in use will not add to the overall length of the iron body 11 so that when the iron body 11 i s resting on i ts rear f ace 14, the cent er of gr avi ty of the iron body 11 is not too high. Normally in use, the reel 17 is removed together with the beaker 28. A ccordingly the reel 17 i s not i nt ended to be a fi xture in respect of the body 11. When the iron 10 is to be stored, thereel 17 i s attached to the bo dy 11.附录二（日本自动卷线专利）。
