BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to an improved cable coiling device for electric heaters, more particularly to a cable coiling device that hides the cable in such a way that the coiled cable will not be exposed and hence gives an artistic, reliable, convenient, and safe effect. 
     2. Description of the Prior Art 
     In the conventional way of coiling a power cable of an electric heater (as shown in FIG.  1 ), an exposed cable coiling frame  20  is disposed near the power cable outlet  101  of the casing  10 , so that the power cable A is coiled and stored on the cable coiling frame  20 . It is undeniable that the cable can be coiled and fixed in the position of the cable coiling frame that is disposed on the external side of the casing, and the value and performance that it offers. After years of practicing the prior art, the manufacturers and users realize that such conventional arrangement still has the following shortcomings: 
     1. The exposed cable coiling frame  20  definitely provides a means for collecting a cable A, but the coiled cable A is easily loosened or bears the risk of falling out if it is not securely tied to the cable coiling frame. Furthermore, it also has the shortcoming of not able to tie securely, stably, and artistically. 
     2. The exposed cable coiling frame  20 , regardless of its situations of coiling or decoiling, gives an inharmonic, inartistic, and inconsistent feeling on the overall external appearance of the heater. Meanwhile, the exposed cable coiling frame may be collided or contacted by human body (especially our foot) that may endanger our safety. 
     Of course, other electric appliance manufacturers at present may use an automatic coiler to collect power cable. However, such automatic cable coiling devices may be very complicated in its structure, and hence may have a greater chance for breakdowns, and mostly important it occupies more space and requires a larger volume of the electric appliances, a more expensive manufacturing cost, and a higher selling price for consumers. Under the principle of pursuing better quality with lower price, the automatic cable coiling devices are limited in their uses and only selected for use depending on the special properties of the type, mode, and selectivity of the merchandise. 
     In view of the shortcomings and inconvenience of the prior art mentioned above, which are the subjects of improvements for a long time, hence the inventor of the present invention based on years of experience accumulated from the engagement in the related industry conducted extensive research to resolve the foregoing shortcomings and invented the present invention. 
     SUMMARY OF THE INVENTION 
     The primary objective of the present invention is to provide an improved structure of a cable collecting device for an electric heater, wherein such cable coiling frame being designed to be built in the outlet of the power cable and following the shape of the casing, and an accommodating hood being disposed on the external periphery, and the accommodating hood being operated with a triggering member for lifting to open and close the hood, thereby makes the cable collection very convenient and the cable will not be exposed loosened. It has the merits of being artistic and harmonic in appearance, and safely secured in position that it would not come off easily. 
     Another objective of the present invention is to provide a simple, easy-to-use, and convenient way to collect cables such that they could be hidden without being exposed. It attains the safety purpose since the hidden device helps to preventing the user from being injured by accidents.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Firstly, please refer to FIGS. 2,  3 ,  4 , and  5 . It obviously shows that the improved cable collecting device of an electric heater mainly comprises an accommodating opening  102  having a concave recession being disposed at the outlet of the power cable of the casing, and a cable coiling frame composed of a plurality of supporting legs  201  being disposed at the center of the accommodating opening  102 , and an accommodating hood  30  for exactly covering the accommodating opening  102  and following the shape of the casing  10 , and a triggering member  40  for the coupling that is disposed between the casing  10  and the accommodating hood  30 ; wherein: 
     said casing  10  has an accommodating groove  103  being disposed at the upper middle and extended upwards at the coupling position of the accommodating opening  102  and the accommodating groove  103 , and a transversal axial rod  104 , and furthermore, at least one latch groove  105  being disposed at the lower end of the accommodating opening  102 ; 
     said accommodating hood  30  being disposed at the external side of the upper middle section, and a guiding groove that exactly corresponds to the accommodating groove  103  of the casing  10 , and a pair of rotary arms  302  being extended inward from the lateral sides of the top of the guiding groove  301 , and a transversal axial rod  303  being disposed between the two rotary arms  302 . In addition, at least one latches being exactly latched to the latch  304  of the latch groove  105  of the casing  10 ; 
     said triggering member  40  being disposed between the guiding groove  301  of the accommodating hood  30  and the accommodating groove  103  of the casing  10 , and being arranged as in the shape of the letter “I” in a horizontal position, in which a vertical triggering panel  401  being disposed at the upper end, and a vertical blocking panel  402  being disposed at the lower end, and a pair of transversal position latch  403 ,  404  with longer length adjacent to the upper end than that adjacent to the lower end; wherein the transversal positioning latch  403  adjacent to the upper end exactly latches the transversal axial rod  303  at the upper end of the accommodating hood  30 , and the transversal positioning latch  404  adjacent to the lower end exactly latches into transversal axial rod  104  at the seam of the accommodating opening  102  of the casing  10  and the accommodating groove  103 , such that the accommodating hood  30  is coupled to the casing  10  by the assembling. Two transversal axial rods  303 ,  304  separately act as the rotation axial points, being disposed at the position of the accommodating opening  102  for up and down swinging movement. 
     Further, refer to FIGS. 6,  7 ,  8 ,  9 , and  10 , the structure of the present invention as disclosed above comprises an accommodating opening  102  being designed to disposed in the concave inward status at the cable outlet  101  of the electric heater casing  10 , and an accommodating hood  30  which exactly covers the accommodating opening  102  according to the shape of the casing so that the cable coiling frame composed of a plurality of supporting legs  201  being disposed at the accommodating opening  102 . It exactly occupies the position in a simple way that does not occupy extra space, and at the same time with the covering of the accommodating hood  30  can hide the coiled cable A (please refer to FIG. 5) giving an artistic look (please refer to FIG.  4 ), and the cable will not fall off easily that provides a safe and secure way for collecting the cables. Of course, it also gives a harmonic, consistent look for the overall appearance of the electric heater, and improves the traditional exposed cable coiling frame by preventing the users from the danger of being injured easily by the exposed frame. 
     The “I” shaped triggering member  40  is disposed adjacent to the lower end of the transversal positioning latch  404  being freely pivotally latched to the transversal axial rod  104  of the casing  10 , and another transversal positioning latch  403  being freely pivotally latched to the transversal axial rod  303  of the accommodating hood  30 . In addition, the vertical triggering panel  401 , the vertical blocking panel  402  at the upper end and lower end respectively locate between the accommodating groove  103  of the casing  10  and the guiding groove  301  of the accommodating hood  30 . Therefore, when the user moves the vertical triggering panel  401  of the triggering member  40  at the accommodating groove  103  of the casing  10 , the triggering member  40  will use the transversal axial rod  104  of the casing  10  as the axial point for the up and down swinging movement (please refer to FIGS. 2,  3 ,  5 , and  7 ). At the same, the transversal axial rod  303  is latched to the accommodating hood  30  of the longer transversal latch positioning latch  403 . As the triggering member  40  swings, it links to move the transversal axial rod  303  up and down. 
     Further, since the triggering member  40  has a transversal position latch  403  at its adjacent upper end is set to be longer than the transversal positioning latch  404  at the adjacent lower end, and a latch  304  is disposed at the inner edge of the lower end of the accommodating hood  30  and also set to be exactly inserted into the latch groove  105  of the lower end of the casing  10 . Therefore, the user can aim the latch  304  at the lower end of the freely swung accommodating hood  30  at the latch groove  105  at the lower end of the corresponding casing  10 . When the vertical triggering panel  401  of the triggering member  40  is lifted upward (please refer to FIGS.  5  and  7 ), the latch  304  at the lower end of the accommodating hood  30  can be inlaid into the latch groove  105  of the casing  10 . Meanwhile, the triggering member  40  adjacent to the upper end has a longer transversal positioning latch  403  will guide the transversal axial rod at the upper end of the accommodating hood  30  inside, and passes the vertical line Y of the transversal axial rod  104  of the casing  10  (please refer to FIG.  5 ), and it will automatically press inward instantly to securely latch into a stable position. 
     If the user wants to open the accommodating hood  30 , the user just needs to move the vertical triggering panel  401  at the upper end of the triggering member  40  outward and downward (please refer to FIGS. 7,  8 , and  9 ), and the upper end of the accommodating hood  30  will be linked to move outward and downward, and the originally inlaid latch  304  of the accommodating hood in the latch groove  105  of the casing will displace downward directly and smoothly until it releases the latch. Then the transversal axial rod  303  at the upper end of the accommodating hood  30  is rotated freely at the transversal positioning latch  403  of the triggering member  40 , and then the user can lift the bottom end of the accommodating hood  30  upward (see FIGS. 8,  9 , and  10 ) such that the entire accommodating hood  30  is in the open position, and then the power cable A can be coiled onto the cable coiling frame  20  smoothly and conveniently. Of course, after the power cable is coiled completed, the user can press the accommodating hood down to hide the cable coiling frame  20  and the power cable A inside, and then latch the latch  304  at the lower end of the accommodating hood  30  into the latch groove  105  at the lower end of the casing  10 , and the triggering member  40  is pressed upward and inward so that the accommodating hood  30  is securely coupled to the casing  10 . The present invention can definitely improve the shortcomings of the traditional exposed cable coiling frame. 
     Therefore, in summation of the above description, the improved structure is the research and development subject for enhancement. The inventor of the present invention based on years of experience in the related industry conducted extensive research to enhance the structure of the storage rack herein which is hereby submitted for patent application.
