Description

  The present invention relates to an electrical product. In particular, the present invention relates to an electrically heated hair dryer.

  Various types of electric heating hair dryers are commercially available while providing attractive functions. Regardless of the variation, commercially available electric hair dryers are composed of two or more separate buttons or switches, or a combination of buttons and switches, for normal operation.

  Typically, at least one button or switch is employed to control the motor driven electric fan unit, while the heating unit is controlled by a separate button or switch. Each of these buttons or switches is further provided to control fans and heating at various levels. For user friendliness, these buttons and switches are usually placed on the handle so that the fingers of the hand holding the hair dryer can be easily reached. Due to the limited size of the handle, there are limits to controlling the fan and heating at various stages. For example, in a full-featured hair dryer with buttons or switches that can adjust both the fan and heating in three steps, level 0 indicates no airflow for the motor, level 1 is normal airflow, and level 2 is Indicates a strong blast. Similarly, levels 0-2 for buttons or switches associated with the heating section indicate no heating, normal heating, and high temperature heating, respectively. Hair dryers can also be featured by adding more separate buttons or switches for function and control.

  Of course, miniaturized hair dryers, portable hair dryers, and travel hair dryers are also commercially available. For simplicity, these hair dryers employ a single switch to switch between normal warm air, normal air blowing, and no air blowing. In addition, such travel hair dryers and general and professional hair dryers are provided with mechanical switches for switching to different voltages.

  In high-power hair dryers (generally 1500 W or more) or professional hair dryers, it is generally not practical to employ dual voltage switching. Such a hair dryer is generally manufactured according to the voltage level of the market or the market.

  It is difficult for the user to control the hair dryer with two or more separate buttons or switches. Limited level control is wasteful in terms of energy usage, and user satisfaction is reduced in many respects.

  There is also a need for a simple and trouble-free hair dryer.

  According to the first aspect of the present invention, a hair dryer having a fan and a heater is provided. A hair dryer is equipped with a programmable integrated circuit (IC), a PCB board to which the fan and the heater are connected, and a plurality of preset switches that define the operating level of the fan and the heater either individually or in any combination. And a multi-mode switch that is connected to the PCB board and controls a plurality of preset switches, the multi-mode switch is placed in a position where it can be operated with one hand on the hair dryer, and the user only has to hold the hair dryer. The hair dryer can control a plurality of preset switches via a multi-mode switch to control the hair dryer.

  In one embodiment, the multimode switch is a rotary dial. In addition, the multimode switch may be configured with a toggle switch. The toggle switch may be switchable up and down or up and down. The toggle switch may be a multidirectional toggle switch that can be switched at least up, down, left and right.

  The multimode switch may be a push button. Further, the button may have a first button and a second button, or may be configured as a single button. In addition, the multimode switch can be any combination of the above-described multimode switches. The multimode switch may be located on the top of the hair dryer handle.

In another embodiment, the hair dryer further comprises a far infrared emitter and ion generator connected to the PCB board, and the operating state of the far infrared emitter and ion generator can be determined by one of the preset switches. . Further, the PCB may have a switching power supply unit and an automatic disconnect circuit.

The invention will now be described by way of non-limiting embodiment of the invention with reference to the accompanying drawings.
