Hair dryer

Description

Field of the Invention

[0001] The present invention relates to an electric appliance. In particular, the present invention relates to an electric hair dryer.

Background

[0002] Electric hair dryers are available in various forms offering attractive features. Regardless of the variations, the electric hair dryers available in the market are configured with two or more of distinct buttons/switches, or combination of both for normal operations.

[0003] Typically, at least one button/switch is adapted to control the motor driving electric fan components, whereas the heating components are controlled by the distinct button/switch. Each of these buttons/switches further provides control of fan and heat in various levels. For user friendliness, these buttons/switches are usually placed at the handle where they are reachable easily through the fingers of the hand holding the hair dryer. Due to the size restrain on the handle, the various levels are limited. For example, a full-featured hair dryer comprises both buttons/switches employing three-level adjustments, wherein, level 0 represents no airflow for the electric component, level 1 represents regular airflow and level 2 represents high airflow for the electric component. Similarly, level 0-2 for button/switch associated to the heating component represents no heat, regular heat and high heat respectively. Some hair dryers can even feature with more distinct buttons/switches as the features and controls increase.

[0004] There are of course some mini- or portable or travel hair dryers available on the market. These hair dryers adopt one single switch that switching between regular heated air, regular air, and no air blow for simplicity. In addition, such travel hair dryers or those ordinary or professional hair dryers, also feature with a mechanical switch for switching between different voltages.

[0005] In high power (generally above 1500W) hair dryers, or professional grade hair dryers, it is generally not practical to adapt dual voltages switching. The hair dryers are generally made to suit the voltage level of intended region/market.

[0006] It can be seen and understood to users that controlling the hair dryer via two or more distinct buttons/switches can be complicated. It can also be wasteful in energy usage due to the limited level controls, and thus decrease users' satisfactions in many regards.

[0007] It can thus be seen that there exists a need for a simple and robust way for a hair dryer.

[0008] WO 80/00783 relates to a hairdryer with an electrical motor that is removable from the housing and incorporates electrical connections which are automatically made as the motor is inserted into position and are automatically broken as the motor is removed. It enables a user of the hair dryer to replace a burn out or otherwise unserviceable motor. The housing further includes a handle portion incorporating an electrical switch assembly. The electrical switch assembly may be a simply on-off switch or a more complex switch assembly such as a slow-off-fast switch and a separate hot-warm switch. The simple on-off switch provides limited control over the fan and heat level, whilst the more complex slow-off-fast switch and the separate hot-warm can be hard to operate for ordinary user.

[0009] EP 1 661 481 A1 relates to a hair dryer in which direction of wind blown from the hairdryer is same as the direction of wind blown from the hair dryer. It requires separates switches at the front portion to control blow strength and heat level individually. These switches are provided at a location where it can be reach conveniently through the fingers of the hand holding the hair dryer. Similarly, the blow strength and heat level controls are limited by the number of buttons available to be placed on the designated location.

[0010] WO2004/098344A1 relates to a hairdryer having a switch patch for providing various controls over the heat, the fan speed and etc. individually Also similarly, due to the multiple switch available, the operation can be complicated.
