Description

Headset type blower fan {headset type blower fan}

The present invention relates to a headset-type blowing fan, and more particularly, to a headset-type blowing fan capable of cooling off heat and sweat of a wearer by blowing air cooled by a refrigerant.

In general, an electric fan is mainly used for the purpose of lowering body temperature and relieving heat by blowing rear air forward by rotating a fan using a motor.

Although the demand for electric fans is gradually decreasing due to the spread of air conditioners in recent years, the demand is still high due to the high cost of energy. It has become a product.

Here, fans are manufactured in various sizes, from small ones that can be used indoors to large ones that can be used in factories, etc., and there are ceiling type, stand type, tabletop type fans and the like depending on the shape or use. The structure of a general electric fan is largely composed of a support, a motor, a propeller, a protective net, an oscillator, a control panel, etc., and is mainly installed indoors and used by connecting power to an outlet.

However, there is a problem in that the fan cannot cool the heat when the indoor air temperature is high or the ambient air temperature is high because hot air is blown by the fan.

Therefore, in order to cool off the heat, other devices than the electric fan must be operated more, so electricity consumption in summer cannot help but increase rapidly.

5 is a side view and a front view of a main body of a headset type blowing fan according to the present invention.

Referring to FIG. 5 , the main body 200 includes a cover member 210, a protective net 220, and a plurality of discharge holes 230.

The cover member 210 includes an inner cover 211 , an outer cover 212 and a filter 213 .

The inner cover 211 is formed at both ends of the band unit 100 to cover the motor unit 300 and the propeller unit 500, and one surface facing the wearer's head may be opened.

The outer cover 212 is formed at the rear of the propeller unit 500 and has a porous structure so that rear air can be easily sucked in.

The filter 213 is provided between the outer cover 212 and the propeller unit 500, and air sucked in by the propeller unit 500 can be purified by the filter 213.

The protection net 220 may be formed to cross the open surface of the inner cover 211 and may be configured to surround the propeller unit 500 from the outside of the propeller unit 500 .

Here, the protective net 220 may be formed in a grill structure that crosses the front surface of the propeller unit 500 or entirely surrounds the propeller unit 500, but the specific shape is not particularly limited, and the rotation of the propeller unit 500 As long as it can protect the wearer from this, it can be appropriately selected and configured as needed.

A plurality of discharge holes 230 may be formed along the outer surface of the inner cover 211, and as shown in FIG. 5, they are formed in a direction toward the wearer's head and in a direction perpendicular thereto to the propeller unit 500. When the wind blown by the wind hits the wearer's head and returns, it can escape through the discharge hole 230. Therefore, since the wind that hits the wearer's head and returns does not interfere with the path of the wind blown by the propeller unit 500, the blowing efficiency can be further improved.

The motor unit 300 may rotate the propeller unit 400 by being installed inside the body unit 200 to generate power. Here, the motor unit 300 may be electrically connected to a separately provided battery (not shown).

6 is a rear view of the refrigerant receiving part of the headset type blowing fan according to the present invention.

Referring to FIG. 6 , the refrigerant accommodating unit 400 includes a storage member 410 , a plurality of ventilation holes 420 and a condensate receiving member 430 .

The storage member 410 is installed along the outer circumference of the motor unit 300 and may be formed in the form of a tube having an internal space capable of storing low-temperature refrigerant therein.

Here, the storage member 410 may be formed of copper, rubber, or aluminum material, but is not limited thereto, and any material may be appropriately selected and configured as needed as long as the thermal conductivity is excellent.

The refrigerant may be composed of ice, dry ice, water or other liquid refrigerant material and is not limited to a specific type. That is, in addition to the above-mentioned various refrigerant materials, there is no particular limitation on the type as long as it is a refrigerant material capable of rapid cooling that rapidly lowers the temperature, and any material may be appropriately selected and configured according to need.

In addition, a plurality of inlets (not shown) may be formed at the upper end of the storage member 410 to supply or discharge refrigerant into the storage member 410, and the inlet may be opened and closed with a separate stopper member provided. It can be configured in any possible form.

The plurality of ventilation holes 420 may be formed through the inside of the storage member 410 and may be spaced apart from each other at regular intervals along the circumferential direction of the storage member 410 .

The condensate receiving member 430 may receive and store condensate generated on the surface of the storage member 410 by being provided with an inclined surface 431 inclined downward from the lower end of the storage member 410 therein.

Hereinafter, a method in which the headset-type blower fan according to the present invention provides the wearer with cold wind due to a low-temperature refrigerant will be described.

As shown in FIG. 6, the inside of the refrigerant accommodating part 400 is filled with low-temperature refrigerant, and hot air from the rear of the refrigerant accommodating part 400 passes through the ventilation hole 420 by the propeller part 500 to the front. In the process of being blown, heat is exchanged with cold air in contact with the inner circumferential surface of the ventilation hole 420, so the air blown forward becomes a low-temperature state. Therefore, heat exchange efficiency is increased during the time when the air at the rear of the refrigerant accommodating unit 400 passes through the ventilation hole 420, so that cool wind can be provided to the wearer.

In addition, condensate generated on the surface of the refrigerant accommodating part 400 during the heat exchange in this way flows to the lower side of the refrigerant accommodating part 400 along the curved surface of the refrigerant accommodating part 400, and then this condensed water flows into the condensate receiver. Since it flows along the inclined surface 431 of the member 430 and is received and stored in the condensate receiving member 430 as shown in FIG. 6, it is possible to prevent safety accidents by preventing short circuits due to condensate.

The propeller unit 500 is connected to the motor unit 300 and blows air cooled by the refrigerant stored in the refrigerant receiving unit 400 to the wearer's head, and is composed of a plurality of fan blades.

The control unit 600 includes a power member (not shown) installed on one side of the motor unit 300 and sending an electrical signal to the motor unit 300 so that the propeller unit 400 can be rotated according to the wearer's selection. It includes a switch 610 for controlling on/off by power supplied by a power supply member.

As described above, the headset type blowing fan according to the embodiment of the present invention has been shown according to the above description and drawings, but this is merely an example and various changes and modifications are made within the scope of the technical idea of the present invention. That this is possible will be well understood by those skilled in the art to which the present invention belongs.
