Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.The present embodiment is implemented premised on technical solution of the present invention, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
Based on a flat energy-saving defroster for charged in parallel electric capacity, as shown in Figure 1, comprising:
Heating part 1, for heating frost and making it melt;
Also comprise:
Dull and stereotyped 2, for fixing heating part 1, dull and stereotyped 2 is circular dull and stereotyped;
Capacitor charge and discharge assembly 3, is connected with dc source 7 and heating part 1 respectively, for powering for heating part 1;
Defrosting rod 4, is located on dull and stereotyped 2, and for frost layer being swept from dull and stereotyped 2 surfaces, defrosting rod 4 is inclination sleeve, and it has been sticked porous media hairbrush 41.
As shown in Figure 2, capacitor charge and discharge assembly 3 comprises:
Capacitance group 33, is made up of multiple Capacitance parallel connection;
Charge switch 31, connects capacitance group 33 and dc source 7 and forms closed-loop path;
Discharge switch 32, connects capacitance group 33 and the heating part 1 be located on dull and stereotyped 2 and forms closed-loop path.
Heating part 1 is plated film resistance, and this plated film resistance is close to dull and stereotyped 2 surfaces.
As shown in Figure 3, defroster also comprises the motor 5 for driving defrosting rod 4 motion, and this motor 5 is connected with the pulse power 6.
In addition, defroster also comprises control circuit, as shown in Figure 4, control circuit comprises three buttons SB1, SB2, SB3 and three relay K A1, KA2, KA3, three buttons SB1, SB2, SB3 connect with three relay K A1, KA2, KA3 respectively, and three relay K A1, KA2, KA3 are respectively used to the opening and closing controlling charge switch 31, discharge switch 32 and starting switch 8.
When the present invention uses, first make SB1 close, allow KA1 relay coil be energized, thus charge switch 31 is closed, capacitance group 33 starts charging.After capacitance group 33 charging complete, control SB1 disconnects, and charge switch 31 is disconnected, and capacitance group 33 stops charging.When needs defrost time, control SB2 closes, discharge switch 32 is closed, capacitance group 33 starts to spark simultaneously, and big current, by plated film resistance, produces amount of heat inside frost layer, it is made to melt rapidly until gasification, be separated between the inner surface of whole frost layer and dull and stereotyped 2, and come off under the effect of the rotation of defrosting rod 4, reach the effect of defrosting.The pulse power 6 provides power periodically to motor 5, makes defrosting rod 4 can against plated film resistance by regulating the angle of inclination of defrosting rod 4.When after frost layer and plated film resistive surface transient evaporation, our control SB3 closes, and makes defrosting rod 4 start slow circumvolves, and under the rotating force of porous media hairbrush 41 thereon, frost layer is swept from dull and stereotyped 2 surfaces, so far completes the whole process of defrosting.
By the abrupt release big current of capacitance group 33, inside frost layer, produce rapidly a large amount of heats provides the thawing of frost layer inner surface to gasify, its inner surface is separated with dull and stereotyped 2, then the defrosting rod 4 that motor 5 controls dull and stereotyped 2 surfaces does Periodic Rotating, by the rotating force of the rod 4 that defrosts, frost layer is cleared out of flat board.By means of this innovation, can the automatic energy saving environmental protection of real implement device.
