Hereinafter, the refrigerant structure (hereinafter simply referred to as 'refrigerant structure') mounted on the portable fan according to the present invention will be described in detail with reference to the attached drawings.

Prior to explanation, the portable fan 10 described below includes a safety net 11 that forms a plurality of holes 12 to allow air to pass through, and is coupled to the safety net 11 so that the user can hold it with his or her hand. , a handle 13 equipped with an external operating switch 14, a blowing fan 15 rotatably installed on the safety net 11, and a rotating force transmitted to the blowing fan 15 by being coupled to the safety net 11. To clearly understand the gist of the present invention, it refers to a typical portable fan (10) consisting of a motor (16) and a battery-type power supply (not shown) installed to be rechargeable inside the handle (13). For this reason, detailed description will be omitted.

First, as shown in FIGS. 1 to 3, the refrigerant structure 1 according to the present invention largely includes a receiving member 100 and a cover member 200.

In more detail, as shown in FIGS. 3 to 5, the containing member 100 replaceably accommodates a solid refrigerant therein, and is fitted with a cover member 200 to be described later to store the refrigerant. The first embodiment includes a body 110 and an extension portion 120 (see FIG. 3) or the body 110 and the extension portion 120 as well as additionally Any one of the second embodiments (see FIG. 6) including the additional extension part 130 and the opening and closing means 140 can be used.

For example, as shown, the body 110 is configured to accommodate refrigerant and includes a receiving space 111 and a through hole 113.

The receiving space 111 is formed inside the body 110 to accommodate the refrigerant, and the body 110 has two parts that can be separated and combined with each other to facilitate replacement of the refrigerant by opening and closing the receiving space 111. It can be molded into a body (see Figure 4).

As shown, the through hole 113 has a perforated shape from one side to the other side of the detachable body 110, and a fitting protrusion 220, which will be described later, is inserted into the through hole 113 to cover it. Satisfies a structure that allows attachment and detachment between the member 200 and the receiving member 100.

In addition, as shown, the extension portion 120 has a shape that protrudes radially from the outer surface of the body 110 centered on the through hole 113, and the inside of each extension portion 120 is a receiving space ( 111) Also, it can be extended so that the area where the refrigerant can be accommodated can be increased.

In addition, it extends from the outer surface of the body 110 so that a first cold air dissipation space 121 is formed between each extension part 120, so that the cold air emitted from the outer surface of the extension part 120 is not only released, but also the body ( 110) The cold air discharged into the first cold air dissipation space 121 through the outer surface can be delivered to the user like external air through the suction of the blowing fan 15.

To this end, the outer surface of the extension part 120 is formed with a gap communicating with the first cold air dissipation space 121 between the inner surface of the enclosure 210, which will be described later, and the suction hole 211 is formed through the rotation of the blowing fan 15. In the process in which external air is sucked in and discharged to the user, a structure in which not only the cold existing in the first cold air dissipating space 121 but also the cold existing in the gap is discharged to the user is satisfied.

Meanwhile, as shown in FIGS. 6 to 8, the additional extension portion 130 including the receiving member 100 in the second embodiment is present in the gap excluding the first cold air dissipation space 121 described above. It is designed to control the amount of cold air emitted to the user and includes a cold air discharge hole 131 and a second cold air dissipation space 133.

For this purpose, as shown, the additional extension part 130 has a predetermined height from the outer surface of the extension part 120, but satisfies a bent structure so that the second cold air dissipation space 133 can be formed between it. .

Meanwhile, as shown, the additional extension portion 130 in the present invention is shown to have a bent structure connected to the outer surface of each extension portion 120, but this is only one embodiment, and the above-mentioned extension portion 130 is shown as necessary. The additional extension part 130 may be formed and used only in some of the plurality of extension parts 120.

The additional extension part 130 formed by bending the outer surface of the extension part 120 may have a cold air discharge hole 131 in communication with the second cold air dissipation space 133 formed through the cold air discharge hole 131. A structure in which cold air existing in the second cold air dissipating space 133 is supplied to the user can be satisfied.

At this time, the cold air discharge hole 131, which is perforated to have a predetermined diameter, is partially or completely closed by the rotating opening and closing means 140, so that the discharge amount of cold air existing in the second cold air dissipation space 133 can be adjusted. It is desirable to have it.

For this purpose, the opening and closing means 140 may include a rotating plate 141 and an adjusting protrusion 143, and the adjusting protruding 143 is exposed to the outside through an adjusting hole 217 formed in the enclosure 210, which will be described later. It is installed to be exposed so that the rotary plate 141 can obtain power to rotate through the user's external force.

As shown, the rotating plate 141 is molded into an overall plate shape using synthetic resin materials, etc., and has the number of additional extension parts 130 and Multiple wings are formed radially in accordance with each other.

Here, a rotating hole having a predetermined diameter may be formed in the center of the rotating plate 141 so as not to interfere with the fitting protrusion 220 inserted into the through hole 113, and the rotating hole may be formed on the front surface of the body 110. The rotating plate 141 can be rotatably coupled through the rotating groove 115 formed in the direction (for example, the blowing fan direction).

At this time, it is preferable that the control protrusion 143 is formed on the outer surface of one of the plurality of wings to have a protruding shape so that it can be exposed to the outside of the enclosure 210.

According to the receiving member 100 of the second embodiment described above, when external air is sucked through the suction hole 211 formed in the enclosure 210 through the blowing fan 15, the sucked air is divided into the first and second cold air. The cold air released into the dispersion spaces 121 and 133 is supplied to the user to provide a cooler feeling.

In this process, if the user wants to reduce the amount of cold air supplied, the control protrusion 143 exposed to the outside of the enclosure 210 is rotated so that the cold air discharge hole 131 is completely or partially covered by the wing. The amount of cold air discharged through the cold air discharge hole 131 can be adjusted, and through this adjustment, the amount of cold air supplied to the user is also adjusted, enabling use according to the user's preference in accordance with changes in weather.

And, as shown in FIGS. 3 and 5, the cover member 200 is coupled to surround the outer surface of the aforesaid accommodating member 100 so that the accommodating member 100 can be mounted on the portable fan 10. In order to ensure that the cold air emitted from the containing member 100 is supplied to the user without being lost, it includes an enclosure 210, a fitting protrusion 220, and a filter plate 230.

For example, as shown, the enclosure 210 has an open shape on one side so that the receiving member 100 can be stored in the storage space 215 formed on the inside, and a plurality of suction holes 211 are perforated on the other side. It is formed to satisfy a structure that allows external air to flow into the storage space 215 through the suction force of the blowing fan 15.

At this time, a plurality of first coupling protrusions 213 are formed radially at the open end of the enclosure 210 to enable detachable coupling with the safety net 11 constituting the portable fan 10.

Meanwhile, in another embodiment of the present invention, an adjustment hole 217 is drilled on the outer surface of the enclosure 210 through which the adjustment protrusion 143 constituting the receiving member 100 according to the second embodiment described above can be inserted. It can be formed, and the length of the adjustment hole 217 is such that the cold air discharge hole 131 is opened and closed when the above-described rotating plate 141 rotates, but does not interfere with the first cold air dissipation space 121. It is formed (see Figure 6).

In addition, as shown, the fitting protrusion 220 protrudes to have a pillar shape in one direction from the other side of the enclosure 210 where the suction hole 211 is formed.

The outer surface of the protruding fitting protrusion 220 is inserted into the through hole 113 formed in the body 110 to couple the body 110 to prevent unwanted separation from the enclosure 210.

At this time, a second coupling protrusion 221 is formed at the end of the fitting protrusion 220 to improve the fixing force of the body 110, and a plurality of incisions are formed on the outer surface to allow penetration into the through hole 113. , It is desirable to ensure that the body 110 and the enclosure 210 are coupled by elastic force.

In addition, as shown, the filter plate 230 is molded into the shape of a ring and has a filter 231 inside, so that it can be exchangeably coupled to the other outer surface of the enclosure 210.

A coupling protrusion is formed on the outer surface of the filter plate 230 in the same manner as the above-described first or second coupling protrusion 221, so that it can be coupled to the enclosure 210. However, if necessary, it can be screwed to the outer surface of the enclosure 210. Thus, purified air in which harmful substances contained in the external air flowing into the storage space 215 through the suction hole 211 have been filtered can be introduced.

According to the refrigerant structure (1) according to the present invention, as shown in FIG. 9, in an external environment such as a hot weather, the refrigerant structure (1) is discharged to the user using only the portable fan (10) without the refrigerant structure (1) installed. The temperature of the wind is provided at a temperature of about 27.1°C to 34.5°C, so it does not provide a very cool wind, but the temperature of the wind discharged to the user when the refrigerant structure (1) is installed has a temperature of about 26.7°C to 34°C. As it is provided with a difference of about 0.4°C to 1.3°C, cooler wind can be provided to the user.

As described above, the refrigerant structure (1) according to the present invention is different from the conventional one by sucking in external air by the blowing fan (15) and emitting cool air from the refrigerant contained in the receiving member (100) when supplying cool wind to the user. As the cold air is supplied to the user, it has the effect of providing even cooler wind.

In addition, unlike in the past, when external air is introduced, purified air filtered of harmful substances through the filter plate 230 is supplied to the user along with cold air, which is expected to have the effect of preventing safety accidents such as skin diseases. I do it.

In addition, the existing portable fan has a limitation in that it does not feel cool because it receives the heated air as it is during the hot summer, but the present invention converts hot air into cold air by using a combined refrigerant, allowing you to feel a cooler breeze. The use of this strong BLDC motor ensures that cool air is quickly delivered to the user without the wind spreading sideways. For example, with natural wind, the wind can be transmitted at 2.6 m/s for 1st stage, 3.5m/s for 2nd stage, and 4.4m/s for 3rd stage.

As described above, the present invention has been described with specific details such as specific components and limited embodiments and drawings, but this is only provided to facilitate a more general understanding of the present invention, and the present invention is not limited to the above embodiments. , those skilled in the art can make various modifications and variations from this description.

Therefore, the spirit of the present invention should not be limited to the described embodiments, and the scope of the patent claims described later as well as all things that are equivalent or equivalent to the scope of this patent claim shall fall within the scope of the spirit of the present invention. .
