Abstract
A microwave oven using DC power which can endure strong vibrations and eliminate noise according to noise standards. The microwave oven includes at least one second choke coil which is arranged outside a magnetron filter box and connected in series to at least one first choke coil installed in the magnetron filter box. Each choke coil and a feed-through condenser constitute a low pass filter. The size of each of the first choke coil is reduced and the size of each of the second choke coil is increased, so as to endure the strong vibrations and eliminate the noise generated by a driving of a magnetron.
Claims25
A microwave oven comprising:
- a magnetron filter box having a magnetron, at least one first choke coil, and a feed-through condenser installed therein;
- and
- at least one second choke coil arranged outside the magnetron filter box and connected in series to the first choke coil, wherein the second choke coil, together with the feed-through condenser, constitute a low pass filter.
A microwave oven comprising:
- a magnetron filter box having a magnetron, first choke coils and feed-through condensers;
- and
- second choke coils arranged outside the magnetron filter box and connected in series to the corresponding first choke coils, wherein the first and second choke coils, together with the feed-through condensers, constitute corresponding low pass filters.
A microwave oven comprising:
- a magnetron filter box having a magnetron and a feed-through condenser;
- and
- choke coils which are installed inside and outside of the magnetron filter box so as to eliminate noise generated by a driving of the magnetron and satisfy vibration standards applied to microwave ovens usable with direct current (DC) power as a power source.
