Figure 5 is a partially cutaway perspective view for showing the structure of the rotary blades 300 used in the warm fan and the fan of the present invention, Figure 6 shows an enlarged cross-sectional plan view.

Rotating blade 300 of the present invention is the front and rear heat dissipation layer (360, 370) of the aluminum material corresponding to each other and the insulating layer (350a, 350b) of the ceramic material applied to the inside of the front and rear heat dissipation layer (360, 370) ) And the other ends 335a and 335b of the copper material which are press-bonded to one side or both sides of the insulating layers 350a and 350b so as to face each other, and protrude out of the rotary blade 300 in connection with them. It consists of the heat generating layer 340 of the electrically conductive paste material hardened | coated and hardened so that an electrode part other end 335a, 335b may be energized between the electrode part ends 334a and 334b and the insulating layers 350a and 350b.

It is preferable that a plurality of perforations 336 are provided at one side of the other ends 335a and 335b of the electrode part fixed inside the rotary blade 300 so that the rotary blade 300 is fixed without being shaken while rotating.

In this case, the other ends 335a and 335b of the electrode part and the insulating layers 350a and 350b may be fixed to each other by using the perforations 336, bolts, rivets, and the like, and press-bond the other ends 335a and 335b of the electrode parts. Some of the insulating layers 350a and 350b may be fixed by passing through the perforations. Of course, it is also possible to use an adhesive or the like.

In the present invention, all the rear of the rotary wing 300 may be configured as a heat dissipation layer, but if the purpose is to send the warm air only in one direction, the rear is also configured as a heat insulation layer using a material for heat insulation rather than heat generation. It is possible.

In addition, it is also possible to wrap the outer case (not shown) outside the rotary wing shown in FIG.

The front and rear heat dissipation layers 360 and 370 have been described as being made of aluminum, but in addition, metal, non-ferrous metal, stone, etc. can be widely used.

An example of the manufacturing method of the rotary blade shown in Figure 5 and 6 are as follows.

First, the aluminum sheet cut to a proper standard is drawn to draw to prevent leakage during coating curing of the insulating layers 350a and 350b and the heat generating layer 340 described below, and the surface is anodized. After securing a predetermined or more dielectric strength, for example, withstand voltage of 1800V or more and insulation resistance of 100 kW, fine dust on the surface is removed to form the front and rear heat dissipation layers 360 and 370.

The insulating layers 350a and 350b formed on the inner surfaces of the front and rear heat dissipation layers 360 and 370 are coated with a ceramic insulating adhesive on the inner surface of the front and rear heat dissipation layers 360 and 370, and a known heat press press. It is made to coagulate | consolidate using etc.

Copper foil is used for the electrode parts 334a, 334b, 335a, and 335b, and one end 334a and 334b of the electrode part protrudes outside the rotary blade 300, and the other ends 335a and 335b of the electrode part. Is formed on the insulating layers 350a and 350b on either side so as not to come into contact with the front and rear heat dissipating layers 360 and 370. For this purpose, two copper thin plates cut to a predetermined size are formed on one side of the insulating layers 350a and 350b. Or it is located opposite to both sides and gradually increases the temperature and pressure, and pressurized pressing for a suitable time and then cooled step by step to bond the copper foil on the insulating layer (350a, 350b), then bubbles, warpage, scratches, etc. The surface of the copper foil plate flatly bonded without corrosion is appropriately etched to complete the other ends 335a and 335b of the electrode part.

7 and 8 illustrate a configuration example of the other ends of the electrode parts 335a and 335b coupled to the insulating layers 350a and 350b in the present invention, and contact the heat generating layer 340 at the other ends of the electrode parts 335a and 335b. Unevenness is formed at the end by corrosion.

On the other hand, one end (334a, 334b) and the other end (335a, 335b) of the electrode portion may be configured using one copper foil, or may be configured using a separate copper foil or copper foil and wire.

When one end 334a, 334b of the electrode portion extending to the outside of the front and rear heat dissipation layers 360 and 370 is not composed of the other ends 335a and 335b and one copper foil, the other end of the electrode portion 334a and 334b and the other end thereof. The 335a and 335b may be variously formed by a connection method such as bolting, riveting, welding, or the like.

The heat generating layer 340 is formed by coating and curing a carbon-based conductive paste on the other ends 335a and 335b of the electrode part. As shown in FIG. 7, when the other ends 335a and 335b of the electrode part are formed to face both sides, the electrode When the other ends 335a and 335b are coated to include the uneven parts, and as shown in FIG. 8, when the other ends 335a and 335b are formed on one side, the cutout portion 341 is formed at approximately the center of the entire coating area. Is applied so that the formed conductive paste is heated by heating at a temperature of about 70 ° C. for about 5 hours to completely remove gas (Gas) in the conductive paste.

Thereafter, the insulating adhesive is applied to the contact surfaces of the front and rear heat dissipation layers 360 and 370, and then the front and rear heat dissipation layers 360 and 370 are adhered to each other by thermal pressing to obtain a completed rotary blade 300. do.

Here, although not shown in detail, the contact portions between the electrode portions 334a and 334b and the front and rear heat dissipation layers 360 and 370 should be provided with a moisture proof structure using silicon malting, and the like. On the outer surface of 360, 370, it is preferable to add a post process such as coating well-known far-infrared radiation paints such as ocher, bioceramic, and anion radiation paint.

When power is applied to the rotary blade 300 having the above configuration, heat is generated in the heat generating layer 340 formed between the other ends of the two electrode portions 335a and 335b, and the heat is before and after the heat dissipating layer 360 and 370. The heat is emitted to the outside to the outside, the heat is generated uniformly in the entire area of the heat generating layer 340, the thermal efficiency is maximized.

On the other hand, since the uneven portion formed at the end of the electrode end (335a, 335b) widens the contact surface with the heat generating layer 340 to the maximum, the heat generating layer 340 and the other end ( Attempts to damage the contacts of 335a, 335b) are actively excluded.

In addition, since the cutout portion 341 is formed at the center of the heat generating layer 340 when the structure is configured as shown in FIG. 8, the current shows a smooth flow over the entire surface of the heat generating layer 340. If the far infrared radiation layer, or anion radiation layer is further configured on the surface of the 370, the far infrared ray, anion emissivity can be maximized.

As described above, according to the present invention, since the blade of the fan is composed of a plate-shaped heating element, the function of the hot fan can be simultaneously performed while maintaining the function of the blade fan.

In addition, since the rotary blade is a plate-shaped heating element, the energy efficiency is high, the consumption current is low, there is an advantage that can solve the life problems due to the disconnection of the heating wire.

In addition, there is also an advantage that there is no room for the disturbance of sleep due to the warm air because the red light does not occur even when executing the warm air function.

In addition, there is an advantage that can affect the promotion of user health by allowing far infrared rays and negative ions to be generated in the rotary wing.
