To being evenly arranged multiple cooling silk screens.
Further, the hot face of the thermoelectric slice is fitted closely with heater strip network edge, reinforces the heat dissipation in hot face, the heat
The huyashi-chuuka (cold chinese-style noodles) of electric piece is fitted closely with cooling silk screen edge, is reinforced the heat absorption of huyashi-chuuka (cold chinese-style noodles), that is, is strengthened the heat exchange between thermoelectric slice and air,
Reduce the heat transfer temperature difference between air and thermoelectric slice.
Further, the heating chamber and cooling chamber are coaxially disposed, and the heating chamber and cooling chamber pass through section as annulus
The thermoelectric slice of shape separates.
The thermoelectric slice is made of the galvanic couple that multiple and different semiconductor materials are constituted.When passing through direct current, galvanic couple is in Paar
Under the action of note effect, heat is absorbed at one end, is formed cold end, while releasing heat in the other end, is formed hot end.Multiple galvanic couples
Collective effect has the effect of freezing and heat so that thermoelectric slice generates huyashi-chuuka (cold chinese-style noodles) and hot face.
A kind of hair dryer, including hair dryer shell, and be arranged in hair dryer enclosure interior and be arranged along air-flow direction
Hair dryer air inlet, blower, thermoelectric heater and hair dryer gas outlet.
Further, grid type hole is disposed with close to thermoelectric heater one end on the hair dryer shell.
Further, the filter screen of filtering sucking air is additionally provided between the blower and hair dryer air inlet.
Further, the hair dryer shell and the thermoelectric heater are coaxial.
Further, temperature detector and temperature controller are additionally provided in the hair dryer shell.
Further, in the hair dryer shell, anion generator, hot-air blowout are additionally provided with behind heating chamber outlet
Afterwards, anion therein can mutually be neutralized with the cation generated because hair mutually rubs with comb, after solving hair dryer
Fluffy problem.
Further, the grid type hole is arranged at the handle of hair dryer shell, and air is after cooling chamber from hand
Handle is discharged downwards, can both cool down the handle of hair dryer, in order to avoid user scalds, the cold wind in turn avoiding the blowout of grid type hole is straight
It connects and blows on user's body a possibility that.
The course of work of hair dryer:
Outside air enters, through filtering under the action of blower via the hair dryer air inlet being located on hair dryer shell
It is divided into two strands by thermoelectric slice after net filtration and blower boosting, one air is entered in heating chamber by heating chamber entrance, is being heated
Intracavitary, air skims over multiple heating silk screens, is heated to be hot-air.Hot-air passes sequentially through heating chamber outlet and hair dryer outlet
Mouth blowout.Another strand of air is entered in cooling chamber by cooling chamber entrance, is led to after multiple cooling silk screens coolings in cooling chamber
The grid type hole that supercooling chamber is exported and is located on hair dryer shell is discharged to the external world.
Compared with prior art, the invention has the following advantages:
1, it using pyroelectric technology, introduces thermoelectric slice and thermoelectric heater is made, efficiency can be effectively improved, reduce cost；
2, cooling silk screen, the heating silk screen fitted closely using edge and huyashi-chuuka (cold chinese-style noodles), hot face reinforces thermoelectric heater and air
Between heat exchange, the temperature of heating elements can be effectively reduced, avoided due to potential risks such as high temperature bring fire；
3, using pyroelectric technology, facilitate temperature control；
4, it by the design of cooling chamber, reduces the high problem of leaving air temp and does not damage head during drying up hair
Hair, more safety and stability；
5, it by setting anion generator, can mutually be neutralized with the cation in hair, it is fluffy after solving hair dryer
Loose problem.
