Heating and blowing apparatus
View Patent ↗A heating and blowing apparatus includes a main body housing having an inlet port and a discharge port. An air flow path extends from the inlet pod to the discharge port. A rotatingly driven fan and a heating unit are arranged on the air flow path. A bypass flow path branches off from the air flow path and leads to an ion emission port. An ion generator including a discharge electrode and an opposing electrode is arranged in the bypass flow path Further, the apparatus includes a cover arranged at the ion emission port and having an opening through which ions pass. One or more protrusions are provided on a rear surface of the cover. The protrusions make contact with the opposing electrode such that the cover is grounded through the opposing electrode.
1. A heating and blowing apparatus comprising:
a main body housing having an inlet port and a discharge port;
a rotatingly driven fan and a heating unit arranged on an air flow path, the air flow path extending from the inlet port to the discharge port;
an ion generator including a discharge electrode and an opposing electrode arranged in a bypass flow path, the bypass flow path branching off from the air flow path and leading to an ion emission port; and
a cover arranged at the ion emission port, the cover having an opening through which ions pass and one or more protrusions provided on a rear surface of the cover, the protrusion making contact with the opposing electrode placed closer to the cover than the discharge electrode is, wherein the cover is grounded through the opposing electrode.
2. The heating and blowing apparatus of 1 , further comprising a biasing unit for pressing the ion generator toward the protrusions of the cover.
3. The heating and blowing apparatus of 1 , wherein the opposing electrode is ring-shaped and the protrusions of the cover are provided in a circumferential direction of the opening for contacting portions of the opposing electrode adjacent an inner circumferential edge of the opposing electrode.
4. The heating and blowing apparatus of 1 , wherein the ion generator includes a cooler for cooling the discharge electrode so as to condense moisture in air into water on the discharge electrode.
5. The heating and blowing apparatus of 1 , wherein the cover is made of an insulating material.
6. The heating and blowing apparatus of 4 , wherein the cooler is a Peltier device.
