Embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is further described.

Referring to Fig. 1-Fig. 5, a kind of mechanical programmed controller comprises shell 1, cover plate 5, drive motors M1, driven wheel 4, reduction gearing mechanism and controlling organization; Reduction gearing mechanism and controlling organization setting in the enclosure, cover plate 5 is fixed on the shell 1 through button bit, drive motors M1 is fixed on shell 1 back side through button bit; Be designed with the through hole that connects on shell and the cover plate 5, screw passes through hole cyclelog is fixed on the dryer panel.Controlling organization comprises: orientation lever 1.2, spring 1.3, driving lever 1.4, output shaft 1.5 and gear combination; Said gear combination comprises: gear 1.11 when cam 1.13, ratchet 1.12 and control, the three be superimposed together and with output shaft 1.5 riveted joints be an integral body, the part of output shaft is passed cover plate 5, reaches outside the cover plate.The one end difference rotational fixation of orientation lever 1.2 and driving lever 1.4 is in shell 1 inboard; Orientation lever 1.2 loose ends are provided with the tooth of right angle trigonometry shape, its hypotenuse place face (see figure 3) that contacts with the tooth of ratchet 1.12, and spring 1.3 is arranged on the not one side of mounting teeth of orientation lever 1.2, and is fixed on shell 1 inboard through Baltimore groove; Cam 1.13 matches with driving lever 1.4.Cam 1.13 surfaces are provided with the groove position of the different radians and the degree of depth; Driving lever 1.4 loose ends are hook-shaped; Its tip is stretched in the groove position of cam 1.13 and along with the rotation of cam 1.13 and in cam face or groove position, is slided, and the back of driving lever 1.4 contacts with the 4th electrode 3.4.One end of the 4th electrode and other three electrodes all is provided with inside the shell, and the other end of four electrodes passes shell and is linked in the circuit.

Reduction gearing mechanism comprises five reduction gearing, the undergear engagement of first reduction gearing 2.1 and second reduction gearing 2.2; The upper gear of second reduction gearing 2.2 designs the number of teeth according to time requirement, and two teeth in the 3rd reduction gearing 2.3 every intervals are provided with a long tooth (see figure 4), the long tooth engagement of the upper gear of second reduction gearing 2.2 and the 3rd reduction gearing 2.3; The 3rd reduction gearing and 2.4 engagements of the 4th reduction gearing, the 4th reduction gearing and 2.5 engagements of the 5th reduction gearing, gear 1.11 engagements when the 5th reduction gearing and control; Driven wheel 4 and 2.1 engagements of first reduction gearing.

When turning output shaft 1.5 to rational position clockwise, can drive ratchet 1.12 and cam 1.13 coaxial equidirectional rotations when gear 1.11 clockwise rotates during control.Cam makes driving lever 1.4 rotate in rotation process, and through the motion of driving lever 1.4, the 4th electrode 3.4 deflects and connects with third electrode electrode 3.3; Drive motors M1, blowing motor M 2 all start at this moment, drive driven wheel 4, reduction gearing mechanism and controlling organization operation by drive motors M1.When cam 1.13 runs to another radian, driving lever 1.4 with the cooperation of groove position under action once more, drive that the 4th electrode 3.4 moves to third electrode 3.3 together and second electrode 3.2 is connected, this moment, heat-generating pipe R energising was also started working.The length of heat-generating pipe R operating time is by the arc length control of cam 1.13 surface groove positions; When cam 1.13 is turning to a certain radian, the 4th electrode 3.4 moves to third electrode 3.3 together and second electrode 3.2 breaks off, and this moment, heat-generating pipe R just quit work.After cam 1.13 had moved one-period, the 4th electrode 3.4 also broke off with third electrode 3.3.

In the running of controller, the ratchet 1.12 in the controlling organization is in the process of turning clockwise, and the elastic force that overcomes spring 1.3 turns over from the profile of tooth of orientation lever 1.2, because the restriction of orientation lever profile of tooth, ratchet 1.12 can't rotate counterclockwise.When the gear on second reduction gearing, 2.2 tops rotates, the long tooth of engagement the 3rd reduction gearing 2.3 in the fixing cycle; When not meshing; The long tooth of the 3rd reduction gearing 2.3 leans against the surface of second reduction gearing 2.2; When guaranteeing the intact meshing gear of the 3rd reduction gearing 2.3 every operations, just stop at the origin-location, prevent that gear from reversing and can guarantee that the running time of gear is more accurate.

This program controller can be realized the clockwise 360 degree rotations of output shaft, and moving 324 clockwise, to spend the time length overall be 162 minutes; In running, the operating time and the duration of while may command dryer heat-generating pipe, this design mainly is to realize that at preceding 6 minutes and back 15 minutes heat-generating pipe quits work, and the equal normal power-up of other times; This is designed with double-deck reverse rotation protection, stable performance; Increase ratchet, realize unidirectional operation.
