Abstract

DC60 (17/01/48) in a heater for de-icing (20) used to defrost stuck and accumulated ice crystals. Stay at the cooler There will be a glass tube part (23), heating wire (21) made of a resistor. Metal mounted inside the glass tube (23), a stopper (22) with lead wire inserts built and a cover covering the opening at both ends of the glass tube (23), and the guide wire ( 24) which goes through the lead wire inserts (22a) and connects to The end of the heating wire (21) in front of the inner wall of the guide hole (22a) of the stopper (22) is protruding (22b, 22c) built in such a way that the diameter of the guide hole (22a). ) Is smaller than the outer diameter of the lead wire (24) in order to seal the gap. Between the stopper (22) and the guide (24), when inserting the lead (24), it is possible to prevent the outside air from entering the gap between the lead (24) and the stopper (22). Therefore can Corrosion protection and Lack of pre-heated wire (21) In a de-icing heater (20) used to defrost adhering and accumulated ice crystals. Stay at the cooler There will be a glass tube part (23), heating wire (21) made of a resistor. Metal mounted inside the glass tube (23), a stopper (22) with lead wire inserts built and a cover covering the opening at both ends of the glass tube (23), and the guide wire ( 24) which goes through the lead wire inserts (22a) and connects to The end of the heating wire (21) in front of the inner wall of the guide hole (22a) of the stopper (22) is protruding (22b, 22c) built in such a way that the diameter of the guide hole (22a). ) Is smaller than the outer diameter of the lead wire (24) in order to seal the gap. Between the stopper (22) and the guide (24), when inserting the lead (24), it is possible to prevent the outside air from entering the gap between the lead (24) and the stopper (22).

Claims (5)

1. An ice dehydrator, characterized by the presence of a glass tube section, a heating wire produced. From a metal resistor installed inside the glass tube, the lead wire connected to the heating wire, a stopper with a hole for inserting the lead wire was built and covered. The openings at both ends of the vial, where the internal wall faces Wire through the aforementioned Such industry cork will have many protruding build. When the wire is not inserted into the diameter of the guide wire as The said part of the hunch is in Smaller appearance Outside diameter of such lead wire When the wire is inserted To the said hump will be attached To the outer edge of the said lead and secure the space between the stopper and the said lead. At the same time, several hunches Such an external force will act because Turning Of such lead wires and even in the event that a gap One such hunch with The lead wire is also spaced. Distant in such a way that the space between The lead wire will be fixed. By another one such hunch 2. Ice heaters as described in Clause 1, which are characterized by that Cork shell for filling And the aforementioned lead wire will be silicone rubber 3. Ice heaters as described in claim 1, which are characterized by that Diameter size The hole of the protruding part is in the range 0.76-0.96 times the diameter of the center line. The outside center of such lead wire 4. Ice heaters as described in claim 3, which are characterized by that The width of the protruding It is in the range 0.2 ~ 1.2 times the outer diameter of the lead wire. 5. Dehydration heaters as described in one of Clause 1 to 4, which are characterized by that They are placed on the bottom of the evaporator. In the freeze cycle, which Use the refrigerant at Has combustible properties
