Embodiment Construction

[0018] Such as figure 1 As shown, the hair dryer comprises a body 2 having a substantially cylindrical shape allowing to constitute a circulation chamber 3 having a longitudinal axis X. The circulation chamber 3 comprises an inlet area 4 and an outlet area 5 . Arranged in this circulation chamber 3 is a circulation system 6 which allows ambient air to be sucked in through the inlet area and then conveyed over the entire length of the circulation chamber 3 for subsequent blowing of the air to the outside of the blower 1 through the outlet area 5 . This circulation system 6 comprises a propeller 7 arranged near the inlet area 4 , a motor 8 allowing to drive the propeller 7 in rotation, and a rectifier 9 arranged downstream of the propeller 7 and allowing to channel the air at the outlet of the propeller 7 . The blower 1 also includes a heating element 10 , arranged downstream of the rectifier 9 , which allows heating of the air in the downstream part of the circulation chamber ...

Abstract

The present invention relates to a hair dryer (1) intended to provide outstanding drying and feel performance while reducing noise. The blower comprises an air circulation chamber (3), an air circulation system (6) and a heating element (10), said air circulation chamber being equipped with an inlet area (4) and an outlet area (5). The blower also comprises a duct (11) arranged in the extension of the circulation chamber. The conduit has an upstream end (12), a downstream end (13) and a neck (14) arranged between said ends, said conduit being arranged between said upstream end and said neck The first part of the gap has a descending angle (α) between 40° and 88° relative to the longitudinal axis (X), the arrangement of the conduit being between the neck and the downstream end The second portion has an opening angle (β) relative to said longitudinal axis, said opening angle being between 1.5° and 3.5°.

Description

technical field [0001] The present invention relates to the field of hair dryers and aims to provide significant drying and feel performance while reducing the noise of the device. Background technique [0002] Traditionally, a hair dryer consists of an air intake area, an air circulation chamber, an air output area, an air circulation system and a heating element. The air circulation system and heating elements are integrated in the circulation chamber. The air circulation system draws in outside air through the entry area, then conveys this air in the circulation chamber from upstream to downstream, and this air passes through the heating elements, the more or less heated air is then blown to the outside through the output area, in order to dry hair. [0003] Known patent application US2013 / 0111777A1 describes a hair dryer configured to increase the air flow at the outlet. To this end, the hair dryer comprises an output head configured to generate a Coanda effect leadin...
