Embodiment Construction

[0015] Hereinafter, the present invention will be described according to the embodiments shown in the drawings.

[0016] Referring to Figs. 1 to 3, a heating and blowing device hair dryer according to an embodiment of the present invention is shown, including a cylindrical main body casing 3 having an air inlet 11 at its rear end and an air outlet 12 at its front end. The grip portion 1 is connected to the rear bottom surface of the main body case 3 .

[0017] The main body casing 3 includes a rear air duct 3 where the motor 20 and a fan 21 are arranged, and a front air duct 4 where the heater 65 is arranged. The front air duct 4 is set in the main body case 3 in a state where an annular air flow path is provided between the front air duct 4 and the inner circumferential surface of the main body case 3 . The front air duct 4 is integrally formed with the rear air duct 2 .

[0018] Most of the wind from the fan moves toward the exhaust port 12 through the front air duct 4, an...

Abstract

A heating and blowing apparatus includes a main body housing (3) having an inlet port (11) and a discharge port (12); a rotatingly driven fan (21) and a heating unit arranged on an air flow path, the air flow path extending from the inlet port (11) to the discharge port (12); and an ion generator (5) including a discharge electrode (51) and an opposing electrode (52) arranged in a bypass flow path, the bypass flow path branching off from the air flow path and leading to an ion emission port (13). Further, it includes a cover (6), arranged at the ion emission port (13), having an opening through which ions pass and one or more protrusions (60) provided on a rear surface of the cover (6), the protrusion (60) making contact with the opposing electrode (52) placed closer to the cover (6) than the discharge electrode (51) is, wherein the cover (6) is grounded through the opposing electrode (52).

Description

technical field [0001] The present invention relates to a heating and drying device, such as a hair dryer, air heater and the like. Background technique [0002] Heating and blowing devices such as hair dryers, air heaters, etc. are used to draw air from the air intake and force this air towards the exhaust air by means of a rotating fan. In such an apparatus, a heating unit is arranged on an internal air flow path, and air heated by the heating unit is discharged through an exhaust port. [0003] In the case of the heating and blowing device having the negative ion generator, a bypass path allowing air to be discharged to the outside without passing through the heating unit is provided on the air flow path extending from the air inlet to the air outlet. The presence of the bypass flow is to avoid the limitation of ion throughput caused by the grid-like elements arranged in the exhaust port. The ion generator is arranged on the bypass flow path (see, for example, Japanese ...
