Abstract
The utility model relates to an electric hot air blower, which belongs to the technical field of household appliances and electrical heating. The core technology of the electric hot air blower lies in that an electric heater installed in the electric hot air blower is composed of a plurality of ceramic basal electric heating plate units. The ceramic basal electric heating plate units are formed by silkscreening resistor and electrode paste on the surface of a good quality ceramic chip with aluminium trioxide. After high temperature sintering, a resistor and electrode film is formed on the surface of a ceramic substrate. Both ends of each ceramic basal electric heating plate unit are fixedly connected with a mica insulating panel, and connecting lead wires are led out. The ceramic basal electric heating plate units can form electric heaters with different section shapes, such as a square, a triangle, a hexagon, a curtain, etc. The ceramic basal electric heating plate units can also generate far infrared rays under heating state, and far infrared can directly promote the blood circulation of the skin. High speed hot blast strongly rubs the surface of the ceramic chip, and negative ions which are helpful for beauty treatment and health are generated. The electric hot air blower of the utility model can be used as an electric hair dryer for beauty treatment, a warm air blower used for household heating, etc.
Description
Technical field
The utility model relates to the electric-heating technology field, relates in particular to the improvement to the electric heater structure of electric calorifier, and the utility model device can be used as the hair drier of beauty treatment and the warm-air drier of family's heating usefulness.
Background technology
The present electrothermal blower fan that generally uses, as the warm-air drier that dries up the hair-dryer of hair and be used for the heating in winter, general all is to adopt the nichrome resistance wire that is wrapped on the mica support as electric heater, Fig. 1 is the internal structure schematic diagram of existing hair drier, and electric heater wherein is entwined by the nichrome resistance wire.The developer has done the different canoes of much making great efforts to attempt by resistance wire and has reduced noise, and Fig. 2 is the existing common several winding forms of hair drier resistance wire, and Fig. 2 A is the turn formula, and Fig. 2 B is a triangular form, and Fig. 2 C is the long arc form.Though some winding form has certain effect to reducing noise, the potentiality of its noise reduction are very limited.Conclusion is got up, and there is following defective in existing electrothermal blower fan:
1. the resistance wire distribution is longer, and the space that occupies is big, and the support complexity, causes that wind resistance is big, produces bigger noise thus;
2. it is inhomogeneous to be easy to cause resistance wire to twine, and it is too high to produce local temperature thus, and the people is felt like a hen on a hot girdle, and the too high easy oxidation scission of resistance wire that also makes of local temperature, has shortened the service life of electric calorifier;
3. resistance wire mainly sends visible light, so the conventional electric heating device can not have physiotheraping effect;
4. resistance wire can be luminous, and the efficient that electric heating transforms is not high, wastes energy.
Summary of the invention
The utility model is at the defective of existing electrothermal blower fan, proposes to adopt that a kind of noise is little, homogeneous heating, has the electrothermal blower fan of certain physiotheraping effect.
The technical scheme that the utility model adopted is, the electric heater of electrothermal blower fan is made up of multi-disc ceramic base electric heating piece unit, and therefore electric calorifier of the present utility model comprises: have casing, fan, gauge tap, the power supply lead wire of inlet and outlet and the electric heater of being made up of multi-disc ceramic base electric heating piece unit.
Described ceramic base electric heating piece unit is to enclose one deck resistive film on the ceramic substrate surface and a kind of novel electric heating piece that forms.This ceramic substrate can be for containing the high-quality potsherd of alchlor, and thickness is 0.6～0.8 millimeter.Described resistive film is the tabular resistance slurry of circuit on the silk-screen of ceramic substrate surface, and the thermal coefficient of expansion of resistance slurry and ceramic substrate are very approaching, form through high temperature sintering again.
Two ends, ceramic base electric heating piece unit and thermal insulation board fixed connection, pick out lead-in wire after, can utilize multi-disc ceramic base electric heating piece unit combination to become the electric heater of different cross section shape, be installed in the electrothermal blower fan.By the different product requirement, ceramic base electric heating piece unit is connected electrically in described gauge tap and the electronic circuit by the mode of serial or parallel connection.
Compare with prior art, electric calorifier of the present utility model has area of dissipation simple in structure, electric heater is big, windage is little, heating is balanced, the thermal efficiency is high, it is little to take up room, advantages such as easy are installed.If the utility model device is applied on hair-dryer and the warm-air drier, can produce following beneficial effect:
1. because windage is little, and it is smooth and easy to ventilate, the rotating speed of fan can reduce, so noise also reduces;
2. because of the electric heating conversion efficiency height, and fan power is little, so energy efficient;
3. the tabular resistive film high conformity of circuit that sinters into behind resistance, the electrode slurry on the silk-screen of ceramic substrate surface, uniformity of temperature profile, long service life;
4. the ceramic substrate of febrile state produces far infrared with quick flow air friction energy, and far-infrared engergy directly promotes the skin blood circulation, has physiotherapy function;
5. the powerful friction heating of hot blast at a high speed ceramic substrate surface can also produce anion, helps beauty treatment healthy.

The specific embodiment
Be further described below in conjunction with the most preferred embodiment shown in the accompanying drawing.
As shown in Figure 3, be 0.6～0.8 millimeter at thickness, contain high-quality ceramic substrate 2 surfaces of alchlor, tabular resistance, the electrode slurry of circuit on the silk-screen, the thermal coefficient of expansion of resistance, electrode slurry and ceramic substrate 2 are very approaching, again through high temperature sintering, ceramic substrate 2 surfaces form the tabular resistive film 3 of circuit, are ceramic base electric heating piece unit 1, are a kind of novel electric heating pieces.
As shown in Figure 4, two ends, ceramic base electric heating piece unit and mica thermal insulation board 4 fixed connections are integral, and draw to connect lead 5 again; Mica thermal insulation board 4 plays the mounting bracket effect, can be combined into difform electric heater by multi-disc ceramic base electric heating piece unit 1.
The multi-disc ceramic base electric heating piece unit combination that Fig. 5 is mounted in the electric heater in the hair-dryer becomes to have the schematic diagram of different cross section shape electric heater, for example can become cross sectional shape by four ceramic base electric heating piece unit combination is tetragonal tubular electric heater (Fig. 5 A), or to become cross sectional shape by three ceramic base electric heating piece unit combination be leg-of-mutton tubular electric heater (Fig. 5 B), can also be combined into the tubular electric heater (Fig. 5 D) of hexagonal tubular electric heater (Fig. 5 C) and curtain type etc.
