Abstract

PROBLEM TO BE SOLVED: To solve the problem that in a conventional fan, when it becomes intense heat at a temperature beyond 30 degrees, wind becomes hot wind to lose a cooling effect.SOLUTION: A cooling fan includes: a blast blade; power means provided at the rear position of the blast blade and rotating the blast blade; a cooling box provided in the rear of the power means; cold insulator storage means stored in the cooling box; and a cold insulator stored in the cold insulator storage means. When the cold insulator is used as it is, the duration of the cold insulator becomes short by the influence of outside air, but the cooling box is provided in the cooling fan, and thereby the influence of the outside air can be minimized.

Description

    The present invention relates to an apparatus for installing a cool box in a fan of a general household, cooling the inside of the cool box by putting a cold insulating agent in the inside, and sending the cold air by placing the cold air on the wind of the fan.

    In the conventional fan, when the temperature reaches a certain temperature or more, the wind of the fan becomes hot air, and the cooling effect is remarkably lost. For this reason, many users refrain from using a fan when the temperature exceeds a certain level, and the only way to obtain coolness is to use a cooler.

    On the other hand, a cooling effect is provided by using a cooling agent inside the electric fan. (For example, refer to Patent Document 1.)

Japanese Patent Laid-Open No. 2012-077773

    The conventional “fan with detachable cooling agent” having a cooling function using a cooling agent has the following problems. First, the cooler is placed inside the aircraft, but the cooler is used as it is, so the structure is very susceptible to the influence of outside air. Therefore, when it became a very hot day exceeding 30 degrees, the duration of the cryogen was shortened due to the influence of outside air. (See Patent Document 1).

    Next, since high-temperature outside air is directly fed into the main body, the temperature inside the main body is likely to rise, and the structure has a structure that can easily affect the cooling agent. Further, since there is no air blowing means for sending the air cooled by the cold-retaining agent forward, the structure is inefficient regarding sending the cold air. (See Patent Document 1).

    Next, no measures have been taken against water droplets caused by melting ice of the cold insulation agent, and when the cold insulation agent was used, the floor was immersed in the water droplets. (See Patent Document 1).

    The present invention is intended to solve the problems of the conventional configuration as described above, and mainly allows the cool wind to be sent by using only the electric fan by using the cooling agent more efficiently. It is a thing.

    The means for solving the first problem is as follows. In order to make it less susceptible to the influence of outside air on the back surface of the electric fan, a cool box is provided, and a cool storage agent storage means is provided inside the cool storage box, and the cool storage agent storage means is loaded with the cool storage agent. The air inside the cold storage is cooled by this cold insulating agent.

    Moreover, in the means for solving the second problem, outside air is taken in from the outside air introduction section and sent to the preliminary cooling means having a heat removal action. The outside air that has been pre-cooled by the pre-cooling means is then sent to a cool box and further cooled. The cooled air is sent from the blower means to the forward discharge part through the cold air communication means extending in front of the fan, the cool air is discharged from the discharge part, and the cold air is diffused by the wind force of the fan.

    Further, in the third means for solving the problem, a water storage means for receiving water droplets is provided at the lower part of the cooler of the electric fan, the water accumulated in the water storage means at the lower part of the electric fan is provided with a water pipe, and through the water pipe to the swinging shaft portion of the electric fan. It is sent to the provided spout.

    According to the first aspect of the present invention, if the cryogen is used as it is, the duration of the cryogen may be shortened due to the influence of outside air. Therefore, it is possible to minimize the influence of outside air by providing a cool box inside the electric fan. It becomes possible to cool the air inside the cold storage more efficiently by putting a cold storage agent into the cold storage.

    According to the second aspect of the present invention, if the outside air is sent directly to the cool box, the temperature inside the cool box may rise. Therefore, it is possible to take in outside air into the cool box after promoting heat removal and pre-cooling through the pre-cooling means having the heat radiating means before sending it to the cool box. After the preliminary cooling is performed by the preliminary cooling means, the air that has entered the inside of the cool box is further cooled by the cooling agent, and the cool air can be efficiently discharged by sending it to the front surface of the electric fan by the blowing means.

    According to the invention of claim 3, the cool air can be discharged from the plurality of discharge portions, and the cool air can be diffused and discharged in a wide range.

    According to the fourth aspect of the present invention, it is possible to collect water droplets generated by the ice of the cold insulation agent by providing the water storage means under the cold storage, and to prevent the floor from being flooded. Then, the water sent from the water storage means to the spray outlet through the water pipe is discharged in the form of a mist, and the cooling effect can be further enhanced by the heat of vaporization by being put on the wind of the electric fan. This makes it possible to effectively use the water accumulated in the water storage means without directly discarding the water.
