Abstract

A hair dryer structure includes a heat generating module having a permanent magnet, a conductor, and a first motor. The motor drives the conductor to rotate after being energized. When the conductor rotates, the conductor rotates to cut the magnetic field. The magnetic lines of force generate an eddy current reaction that generates thermal energy on the conductor, which is then sent by the air supply device to the outside through the conductor.

Description

Hair dryer structure

The present invention relates to a hair dryer structure which is a structure in which an eddy current is generated by a permanent magnet to heat the conductor.

The commonly used hair dryer is mainly divided into four parts, which are divided into control switch, electric heating element, air supply element and inlet/outlet air outlet, wherein the control opening relationship is used to control the hair dryer power switch and the strong/medium/weak air volume, but such The design can only be limited to blowing only hot air. The functional hair dryer has a different temperature control switch, in addition to adjusting the air volume of the air supply, which can not only blow hot air but also blow cold air. In the early days, the electric heating element was wrapped around a ceramic plate with nickel-chromium wire, and a layer of mica-insulated heat-insulating sheet was placed on the periphery to avoid contact with the plastic case. However, most of the hair dryers today use the technology of thermal catalyst. Avoid the aging of the nickel-chromium wire. If the blower does not blow hot air when it is used, or sometimes it will suddenly emit a spark, it is a problem caused by the aging fracture of the nickel-chromium wire. The air supply component includes a second motor and a blade. The second motor is electrically connected to the control switch. When the control switch is turned on to activate the second motor, the second motor drives the blade to rotate and generates an air volume, and the air volume passes. The electric heating element blows hot air through the air outlet. If the hair dryer does not respond after starting the control switch, the first safety device can be inspected first, and then the second motor and the blade are damaged. The inlet/outlet is for the purpose of When the blade is rotated, the air inlet is used to bring in the wind, and then the air is discharged by the air outlet. During this period, the electric heating element is used to change the temperature of the wind. If the air inlet is blocked by foreign matter such as hair or dust, the wind may be caused by the blower. Large reduction, which in turn makes the temperature of the heating element If the temperature is too high, the temperature of the body will increase. It will cause the safety device to jump off. If the hair dryer is automatically turned off when it is used, it may be caused by too much hair, dust or foreign matter inside. After the district is opened and cleaned up, it can continue to be used.

Today's hair dryers are mostly between 400 watts (W) and 1400 watts (W). The power of a typical household hair dryer is between 800 watts and 1000 watts. In other words, the household hair dryer lasts for an hour. Consuming 1 degree of electricity, the power consumption of the hair dryer is higher than that of TV, oven, electric cooker and microwave oven. If the hair dryer blows for 1 hour a day, the electricity price is 3 yuan, then 30 degrees will be spent in one month. The electricity, that is to say, the extra electricity fee of 90 yuan, so the extra cost for the family is also an extra expense.
