Problems solved by technology
[0007] Currently known hair dryers present fundamental safety concerns due to the presence of live parts that are fully exposed to the external environment, and because they may accidentally come into contact with water, thus causing potentially fatal electric shocks to the user
[0008] In addition to the well-known accidents caused by accidentally dropping a hair dryer in a bathtub or washbasin, there is another, more dangerous form of accident caused by water accidentally entering the hair dryer when it is not in use.
In these cases, where the user is unaware that water has infiltrated and reactivates the hair dryer's motor, a short circuit is triggered in the resistance that heats the air in the motor, or worse, in the button of the hair dryer, creating a potential fatal electric shock

Embodiment Construction
[0020] figure 1 Reference numeral 1 in the figure generally denotes a hair dryer according to various embodiments of the present invention.
[0021] The hair dryer 1 comprises a housing 2 which extends along a longitudinal axis X1 and in which a flow tube 4 is arranged.
[0022] The flow tube 4 is in fluid communication with the external environment by means of an inlet port 4IN and a delivery port 4OUT. Inside the flow tube 4, a rotor 6 and a motor unit 8 are arranged coaxially with the axis X1, the motor unit 8 comprising a motor M configured to drive the rotor 6 in rotation about the axis X1.
[0023] The rotor 6 may be driven in rotation for drawing airflow through the port 4IN and sending the airflow through the flow tube 4 towards the port 4OUT.
[0024] Furthermore, at least one electrical resistor is arranged in the flow tube 4 and is designed to heat the air flow sucked in by the rotor 6 . In the embodiment shown in the figures, the hair dryer 1 comprises a first r...

Described herein is a hairdryer (1) including: - a casing (2); - a flow duct (4) provided within the casing (2) and having an intake port (4IN) and a delivery port (40UT); - a motor unit (8) includingan electric motor (M); - at least one rotor (6), which can be driven in rotation by the electric motor (M) and is configured for sucking in an air flow through the intake port (4IN) and sending it into the flow duct (4) towards the delivery port (40UT); and - at least one electrical resistance (10, 12) inserted in the aforesaid flow duct (4) and configured for heating the air flow taken in by theaforesaid rotor (6). The above at least one electrical resistance (10, 12) is coated with electrically insulating material, and the motor unit (8) includes a watertight casing (16) housing the electric motor (M).
Description
technical field [0001] A hair dryer, comprising: [0002] -shell, [0003] - a flow tube disposed in said housing and having an inlet port and an outlet port, [0004] - motor units including electric motors, [0005] - at least one rotor rotatably operated by means of said electric motor and configured for drawing airflow through said inlet port and sending airflow into said flow tube towards said outlet port, [0006] - At least one electrical resistance inserted into said flow tube and configured to heat the air flow entrained by said rotor. Background technique [0007] Currently known hair dryers present fundamental safety concerns due to the presence of live parts fully exposed to the external environment, and since they may accidentally come into contact with water, thus causing potentially fatal electric shocks to the user. [0008] In addition to the well-known accidents caused by accidentally dropping a hair dryer in a bathtub or washbasin, there is another, mo...
