This application claims priority from Republic of Korea Patent Application No. 10-2023-0057129, filed on May 2, 2023, which is hereby incorporated by reference in its entirety.
The present disclosure relates to a refrigerant structure used in a portable fan, which is mounted to be removable from the portable fan, and blows cold air by refrigerant to allow a user to feel a cooler wind.
In general, a portable fan is a device that reduces the size and weight for a user to carry, and the portable fan is widely used in recent years because the user can carry the portable fan in hand or carry the portable fan in a bag.
Such a conventional portable fan is constituted by a safety net having multiple holes so that air can pass through, a handle coupled to the safety net so that the user can grip with a hand and having an operation switch provided outside, a blowing fan rotatably installed in the safety net, a motor coupled to the safety net and transferring rotational force to the blowing fan, and a power supply unit chargeably installed inside the handle.
The conventional portable fan has a structure in which when a motor is driven by manipulating the operation switch, if the motor is driven by using power of the power supply unit, the air is introduced into a rear side through a hole of the safety net while the blowing fan rotates, and then the air is blown to the front side of the safety net.
However, the conventional portable fan has an advantage in that the conventional portable fan can be used while moving, but in particular, when the conventional portable fan is used outside in a scorching season, there is a problem in that a cool wind is not blown as compared with a mounting type fan.
Moreover, since the conventional portable fan has a driving scheme which introduces outdoor air into the safety net and concentrates the outdoor air at a human body (face, neck, etc.) of the user, when the conventional portable fan is used in an atmospheric environment having a high fine dust index, there is a concern about hazardous substances entering a respiratory of the user, and there is a concern about heat generated upon driving the motor being transferred to the user.
In order to solve the problem in the related art, the present disclosure has been made in an effort to allow a cooler wind to be blown at the time of sucking air from a rear side by using a portable fan, and then blowing the sucked air to a front side which is a user direction.
The present disclosure has also been made in an effort to allow a wind blown to a user to be blown in a state in which hazardous substances are removed from the wind.
In an aspect, a refrigerant structure removably mounted on a rear side of a portable fan into which air is introduced is provided. The refrigerant structure includes: an accommodation member 100 accommodating refrigerant; and a cover member 200 fitted and coupled to the accommodation member 100 to cover the accommodation member 100 inside and removably coupled to the portable fan, and having a suction hole 211 to introduce the air, and the accommodation member 100 includes a pair of bodies 110 to be removed from and coupled to each other, and having an accommodation space portion 111 accommodating the refrigerant therein, a through-hole 113 perforated up to the other surface from one surface of the body 110 not to be in communication with the accommodation space portion 111 and to which the accommodation member 100 may be fitted and coupled, multiple extension portions 120 radially protruded on an outer surface of the body 110, and a first cold air emission space portion 121 formed between the body 110 and the extension portion 120, and formed so that the air introduced through the suction hole 211 may be blown to a front side through the portable fan jointly with cold air by the refrigerant.
In addition, it is preferable that the cover member 200 includes an enclosure 210 having a first coupling protrusion 213 removably coupled to the portable fan formed at an opened front side, and the suction hole 211 formed at a rear side, and a storage space portion 215 for accommodating the body 110 formed inside, and a fitting protrusion 220 in which multiple second coupling protrusions 221 radially protruded to have elastic force toward the front side from the rear side of the enclosure 210, and inserted into the through-hole 113, and fitted and coupled to the body 110 at an end portion.
In addition, it is preferable that the accommodation member 100 further includes an additional extension portion 130 in which a second cold air emission space portion 133 may be formed inside multiple respective extension portions 120 radially formed on the outer surface of the body 110, and a rear side of the additional extension portion 130 is opened, and a cold discharge hole 131 is perforated at a front side to allow the air introduced through the cover member 200 to be blown to the front side of the portable fan jointly with cold air present in the second cold air emission space portion 133.
In addition, it is preferable that the accommodation member 100 further includes an opening/closing means 140 for opening/closing an opened diameter of the cold air discharge hole 131, and the opening/closing means 140 includes a rotation plate 141 rotatably coupled onto a front surface of the body 110, and an adjustment protrusion 143 extended on an outer surface of the rotation plate 141 to penetrate an adjustment hole 217 formed in the cover member 200.
In addition, it is preferable that the refrigerant structure further includes a replaceable filter plate 230 provided on an outer surface of the cover member 200.
According to the present disclosure, there is an effect that cool wind is supplied to a user jointly with cold air emitted from refrigerant accommodated in an accommodation member at the time when outdoor air is sucked by a blowing fan and the cool wind is supplied to the user, so cooler wind can be supplied differently from the related art.
Further, an effect is expected, in which purified air in which the hazardous substances are filtered through a filter plate is supplied to the user jointly with the cooling air at the time of introducing the outdoor air, so a safety accident such as skin disease can be prevented differently from the related art.
Further, the related art has a limit in that in respect to the conventional portable fan wind, hot air in the hot summer season is transferred as it is, so the user cannot feel cooling, but in the present disclosure, there is an effect in which by combining and using the refrigerant, a hot wind is converted into a cold wind to allow the user to feel a cooler wind, and the cool wind is rapidly transferred to the user without spreading toe the side by using a BLDC motor having strong straightness.

First, as illustrated in
More specifically, as illustrated in
For example, as illustrated, the body 110 as a component for accommodating the refrigerant includes an accommodation space portion 111 and a through-hole 113.
The accommodation space portion 111 may be formed inside the body 110 to accommodate the refrigerant, and the body 110 may be molded into two bodies to be removed from and coupled to each other to easily replace the refrigerant by opening/closing the accommodation space portion 111 (see
As illustrated, the through-hole 113 has a perforated shape toward the other surface from one surface of the removable body 110, and satisfies a structure in which a fitting protrusion 220 to be described below is inserted into the through-hole 113 to attach/detach the cover member 200 and the accommodation member 100 to/from each other.
Further, as illustrated, the extension portion 120 has a shape in which multiple extension portions 120 radially protrude on an outer surface of the body 110 around the through-hole 113, and the accommodation space portion 111 may also be extended to increase an area of the inside of each extension portion 120 capable of accommodating the refrigerant.
Moreover, cold air extended from the outer surface of the body 110 and discharged from the outer surface of the extension portion 120, and cold air discharged to the first cold air emission space portion 121 through the outer surface of the body 110 may be transferred to the user air through suction of the blowing fan 15 like the outdoor air so that a first cold air emission space portion 121 may be formed between respective extension portions 120.
To this end, an interval through which is in communication with the first cold air emission space portion 121 is formed between the outer surface of the extension portion 120 and an inner surface of an enclosure 210 to be described below, so a structure is satisfied in which in a process in which the outdoor air is sucked from a suction port 211 through rotation of the blowing fan 15 and discharged to the user, the cold air which is present in the first cold air emission space portion 121 and the air which is present in the gap are discharged to the user jointly.
Meanwhile, as the second exemplary embodiment, as illustrated in
To this end, as illustrated, the additional extension portion 130 has a predetermined height from the outer surface of the extension portion 120 and satisfies a structure in which the additional extension portion 130 and the extension portion 120 are linked to be bent so that a second cold air emission space portion 133 may be formed therebetween.
Meanwhile, as illustrated, it is illustrated that the additional extension portion 130 has a structure bent to be linked from the outer surface of each extension portion 120, but this is just one exemplary embodiment, and as necessary, it is also possible that the additional extension portion 130 is formed and used only in some of multiple extension portions 120.
The additional extension portion 130 bent on the outer surface of the extension portion 120 may have the cold air discharge hole 131 perforated, which is in communication with the second cold air emission space portion 133, and may satisfy a structure in which the cold air present in the second cold air emission space portion 133 is supplied to the user through the cold air discharge hole 131.
In this case, it is preferable that the cold air discharge hole 131 perforated to have a predetermined diameter is partially or wholly closed by the rotating opening/closing means 140 to adjust the discharge amount of the cold air present in the second cold air emission space portion 133.
To this end, the opening/closing means 140 may include a rotation plate 141 and an adjustment protrusion 143, and the adjustment protrusion 143 is installed to be exposed to the outside through an adjustment hole 217 formed in the enclosure 210 to be described below to obtain a power to rotate the rotation plate 141 through external force of the user.
As illustrated, the rotation plate 141 is molded in a plate shape as a whole by using a synthetic resin material, and has multiple blades formed radially, which match the number of additional extension portions 130 so as not to interfere with the cold air discharged to the first cold air emission space portion 121.
Here, a rotation hole having a predetermined diameter may be perforated at the center of the rotation plate 141 so as not to interfere with the fitting protrusion 220 inserted into the through-hole 113, and the rotation hole enables the rotation plate 141 to be rotatably coupled through a rotation groove 115 formed on a front surface (e.g., toward the blowing fan) of the body 110.
In this case, it is preferable that the adjustment protrusion 143 is molded to have a protruded shape on the outer surface of any one of multiple blades to be exposed to the outside of the enclosure 210.
By the accommodation member 100 which is the second exemplary embodiment, when the outdoor air is sucked through the suction hole 211 formed in the enclosure 210 through the blowing fan 15, the cold air discharged to the first and second cold air emission space portions 121 and 133 as the sucked air is supplied to the user to provide a cooler feeling.
When the user intends to reduce the amount of the supplied cold air in such a process, the amount of the cold air discharged through the cold air discharge hole 131 may be adjusted as the entirety or a part of the cold air discharge hole 131 is hidden by the blade by rotating the adjustment protrusion 143 exposed to the outside of the enclosure 210, and the amount of the cold air supplied to the user is also jointly adjusted through such adjustment to use the portable fan according to a user's preference to suit a weather change.
In addition, as illustrated in
For example, as illustrated, the enclosure 210 has a shape in which one side is opened so that the accommodation member 100 may be stored in a storage space portion 215 formed inside, and satisfies a structure in which multiple suction holes 211 are perforated at the other side and the outdoor air may be introduced into the storage space portion 215 through suction force of the blowing fan 15.
In this case, multiple first coupling protrusions 213 are radially formed at an opened end portion of the enclosure 210 to be detachably coupled to the safety net 11 constituting the portable fan 10.
Meanwhile, the adjustment hole 217 into which the adjustment protrusion 143 constituting the accommodation member 100 according to the second exemplary embodiment as another exemplary embodiment may be penetrated and inserted may be perforated on the outer surface of the enclosure 210 in the present disclosure, and a length of the adjustment hole 217 is formed as a length not to interfere with the first cold air emission space portion 121 while the cold air discharge hole 131 is opened/closed when the rotation plate 141 rotates (see
Further, as illustrated, the fitting protrusion 220 is protruded to have a pillar shape toward one side from the other side of the enclosure 210 with the suction hole 211.
The outer surface of the protruded fitting protrusion 220 is penetrated and inserted into the through-hole 113 formed in the body 110 and coupled to prevent undesired departure of the body 110 from the enclosure 210.
In this case, a second coupling protrusion 221 is formed at an end portion of the fitting protrusion 220 to enhance fixation force of the body 110, and when multiple incisions are formed on the outer surface and penetrated and inserted into the through-hole 113, it is preferable that the body 110 and the enclosure 210 are coupled by elastic force.
Further, the filter plate 230 is molded in a ring shape as illustrated, and has a filter 231 provided therein and is replaceably coupled to the outer surface of the other side of the enclosure 210.
A coupling protrusion is protruded on the outer surface of the filter plate 230 similarly to the first or second coupling protrusion 221 to be coupled to the enclosure 210, but as necessary, the coupling protrusion is screw-coupled to the outer surface of the enclosure 210, so purified air generated by filtering the hazardous substances included in the outdoor air introduced into the storage space portion 215 may be introduced through the suction hole 211.
By the refrigerant structure 1 according to the present disclosure, a temperature of a wind ejected to the user only by the portable fan 10 in a state in which the refrigerant structure 1 is not mounted in an external environment such as a severe hot season is provided as a temperature of approximately 27.1° C. to 34.5° C., and a very cool wind is not provided, but the temperature of the wind ejected to the user in a state in which the refrigerant structure 1 is mounted is provided as a temperature of approximately 26.7° C. to 34° C., so the temperatures are provided to show a difference of approximately 0.4° C. to 1.3° C., thereby providing a cooler wind to the user.
As described above, according to the present disclosure, the refrigerant structure 1 has an effect that the cool wind is supplied to the user jointly with cooling air emitted from the refrigerant accommodated in the accommodation member 100 at the time when the outdoor air is sucked by the blowing fan 15 and the cooling wind supplied to the user, so cooler wind can be supplied differently from the related art.
Further, an effect is expected, in which purified air in which the hazardous substances are filtered through the filter plate 230 is supplied to the user jointly with the cooling air at the time of introducing the outdoor air, so a safety accident such as skin disease can be prevented differently from the related art.
Further, the related art has a limit in that in respect to the conventional portable fan wind, hot air in a scorching season is transferred as it is, so the user cannot feel cooling, but in the present disclosure, there is an effect in which by combining and using the refrigerant, hot wind is converted into cold wind to allow the user to feel cooler wind, and the cool wind is rapidly transferred to the user without spreading toe the side by using a BLDC motor having strong straightness. For example, the wind can be transferred at 2.6 m/s in a natural wind and a first stage, 3.5 m/s in a second stage, and 4.4 m/s in a third stage.
As described above, the present disclosure has been described by specified matters such as detailed components, and the like and limited exemplary embodiments and drawings, but the description is just provided to assist more overall understanding of the present disclosure and the present disclosure is not limited to the exemplary embodiment and various modifications and changes can be made by those skilled in the art from such a disclosure.
Accordingly, the spirit of the present disclosure should not be defined only by the described exemplary embodiments, and it should be appreciated that claims to be described below and all which are equivalent to the claims or equivalently modified are included in the scope of the present disclosure.
