Description

The present invention relates to a rapid-cooling portable electric fan that can rapidly cool the electric fan of a portable (hand-held) electric fan using dry ice to enjoy cool air indoors and outdoors.

A portable fan that has a small built-in rechargeable battery, can be charged outdoors from the USB terminal of a PC, and can be carried outdoors, and the wings of the fan can be rotated by the power of the charged battery to enjoy the wind of the fan with a handheld type. It is becoming popular.

With a portable (hand-held) fan, the amount of air is not sufficient, and only the fresh warm air of the outside air is blown, and it is not easy to send a sufficiently cool fan.

Various attempts have been made to cool the wind of the fan. For example, Patent Literature 1 describes an electric fan and a cool air device for an electric fan that evaporate water by a fan and supply cool air whose temperature is lowered by heat of vaporization. As shown in FIG. 11, in the cool air device 1120 of the cool air fan 1110, the water diffusion cloth 1121 is supported by the flat plate grid-like support portion 1122, and the cover connection portion fixture 1123 and the fan drive portion fixture 1124 are used. The fan 1110 is vertically arranged on the front surface.

As shown in FIG. 12, the water medium from the water supply cylinder 1205 is supplied and permeates the water diffusion cloth 1201, and the planar water diffusion cloth 1201 supported by the plane grid-like support portion 1202 conducts heat conduction. A plurality of ventilation holes 1212 are provided by a metal material having good properties such as aluminum, and the heat of vaporization is taken away by the water that permeates around the ventilation holes 1212 of the water diffusion cloth 1121 and flows down to lower the temperature. The cool air is blown through the plurality of ventilation holes 1212 and the water diffusion cloth 1201.
However, it is not easy to sufficiently lower the temperature of the cool air by the method of lowering the temperature of the air by the heat of vaporization of water as in Patent Document 1.

Further, Patent Document 2 describes a cold air fan, and as shown in FIG. 13, a four-stage hanging bracket 1301 is attached to an electric fan 1304, and ice or dry ice is attached to the first to third stages. It describes a fan 1304 that puts a frozen PET bottle and a small box 1302 containing a cooling agent on the fourth step small box 1303 as a water receiver for receiving drops, and it is dry to cool the wind of the fan. The use of ice has also been shown.
However, in the case of Patent Document 2, the dry ice is just the ones enumerated as being put in the small box 1302, like the ice, the frozen PET bottle, and the ice pack, and the water receiver that receives the drop. The small box 1303 is also indispensable and is not specially devised to cool the wind of the fan with dry ice.

Further, Patent Document 3 describes a portable ice pack fan in which an ice pack frozen in a freezer is mounted on the back of an existing portable fan, and is driven by a dry battery 1406 as shown in FIG. It is shown that the ice pack 1404 is attached to the rear surface form portion 1405 of the fan fan 1403 and the wind cooled by the ice pack 1404 is directed to the front surface by the fan fan 1403.
However, the ice pack 1404 is for freezing in a freezer and does not cool the wind of the fan with dry ice.

Further, Patent Document 4 describes a carbon dioxide fan. As shown in FIG. 15, one end of a stand 1502 is connected to a fan body 1501 and the other end of the stand 1502 is connected to a carbon dioxide box 1503. The carbon dioxide box 1503 is installed in the vent hole of the fan main body 1501, and a guard 1504 is provided on the carbon dioxide box 1503.
However, Patent Document 4 also describes that “a block of carbon dioxide is arranged in a box of carbon dioxide”, and only the use of a solid block of dry ice is shown.

A front surface portion having a tubular portion, a rear surface plate provided with a large number of pores, a rear tubular portion and a rear surface portion having a plurality of horizontal partition plates are formed in combination to form the front surface plate and the rear portion. The space between the face plate stores and holds the granular or powdery dry ice in each section of the plurality of sections divided by the cylindrical portion, the rear tubular portion, and the plurality of horizontal partition plates. Is possible.

In the rapid-cooling portable fan of the present invention, the fan that has entered a large number of pores in the rear face plate passes through the inside of the granular or powdery dry ice and comes into contact with the granular or powdery dry ice to be rapidly cooled. By operating the handheld fan in a high temperature environment, dry ice is used to blow cold air, whose temperature has dropped sufficiently, from a large number of pores on the front plate without damaging the air volume of There is an advantage that the temperature of the fan can be lowered rapidly.
