The specific embodiment
As Fig. 1-shown in Figure 6, power spring 1 is the thin-wall metal spring of airtight similar air spring, and according to its design feature, its length variations amount is bigger when temperature raises or reduce.The effect of heat-insulation layer 2 is to guarantee the thin-wall metal spring of airtight similar air spring as 1 main and ice mould 3 and the electric hot plate 12 generation heat exchanges of power spring, and is few as far as possible with the heat exchange of external environment.The main effect of ice mould 3 is to make water form the ice of easy demoulding shape, and its material is a thermal conductivity material preferably.Drag-line 4 one ends are connected the other end with the foreign steamer of ratchet device 5 and are connected with power spring 1, and effect is the transmission of finishing power spring 1 and 6 power of wind spring by ratchet device 5.Ratchet device 5 can only unidirectionally rotate, and interior wheel is fixed with dialling ice bar rotating shaft 7, and the inner of foreign steamer and wind spring 6 is fixed.Wind spring 6 is a volute spring, its outer end is fixed with the ice mould, the ice that to ice in the mould 3 when dialling ice bar rotating shaft 7 rotations is transferred to, wind spring 8 also is a volute spring, its the inner is connected with runner 9, and the outer end is connected with ice mould 3, and main effect is when the foreign steamer of drag-line 4 pulling ratchet devices 5 rotates, produce damping by runner 9 and the interior wheel of dialling 7 pairs of ratchet devices 5 of ice bar rotating shaft, when the foreign steamer of ratchet device 5 is rotated in wheel motionless; Finish when dialling the ice action when dialling ice bar rotating shaft 7, dialling ice bar rotating shaft 7 can automatically reset, runner 9 is connected and fixed with group ice bar rotating shaft 7, runner 9 drives drag-lines 11 water intakings when dialling the rotation of ice bar, the purposes of water inlet pipe 10 is that a certain amount of water is imported ice mould 3, electric hot plate 12 is connected with time-delay microswitch 13, and microswitch 13 is for often leaving the time-delay cut-off switch.
The piston type supply channel is made of the piston pump 15 of two check valves 14,17 and middle series connection thereof, the brake cable drag-line of coiling interlock mutually on the piston of piston pump and the runner, and the inlet of supply channel links to each other with water receiver, exports with the water inlet pipe 10 of icing mould to link to each other.Water level switch 16 is a normally closed switch, when dropping to a certain degree, liquid level disconnects, and the direction of check valve 14,17 control current, and under certain pressure, just can open, 15 is the piston of simple and easy hydraulic cylinder, the principle of check valve 17 is with check valve 14.
During use, ice machine is packed in the household freezer, water intaking mechanism is contained in outside the case.In the water freezing process in ice mould 3, the temperature of the power spring 1 under the ice mould 3 is along with the temperature of ice mould reduces together, the length of power spring 1 is shunk at this moment, foreign steamer by drag-line 4 pulling ratchet devices 5 when shrinking rotates, because the damping action of wind spring 6, the interior wheel of ratchet device 5 is motionless, drives wind spring 6 when ratchet device 5 foreign steamers rotate and rotates, wind spring 6 savings energy.
When the temperature of power spring 1 dropped to design temperature, power spring 1 touches microswitch 13 electric hot plates 12 started working, and the back length of being heated of power spring 1 begins to recover, beginning ice after ice mould 3 is heated.The time of heating will guarantee that the length of power spring recovers fully, and ice is thrown off fully with the ice mould.
When the length of power spring 1 was recovered, the energy of wind spring 6 began to discharge, and drove group ice bar rotating shaft 7 rotations by ratchet device 5 and will ice dial-out.
When dialling the rotation of ice bar, drive wind spring 8 and drag-lines 11 by runner 9.Wind spring 8 rotates the savings energy, drag-line 11 action of fetching water, and water intaking is moved as shown in Figure 6, when drag-line 11 pulling pistons 15, check valve 4 is opened check valve 17 and is closed, water inlet in the cylinder, when dialling the rotation of ice bar, because the damping action of drag-line 11 can be controlled out the speed of ice.
After the energy release of wind spring 6 reached balance, wind spring 8 drove group ice bars and resets, and this moment, piston 15 also resetted, and check valve 14 is closed check valve 17 and opened, and begins water inlet in the ice machine.Enter next circulation, the liquid level in tank drops to a certain degree, and water level switch 16 disconnects, and ice machine quits work.
