Description

  The present invention relates to a cold air generating apparatus used when spending outdoors in a room without air conditioning or during outdoor heat, or when partially cooling the body with ice or a freezing agent in a hospital or the like. The present invention relates to a cold air generating apparatus in which an apparatus and a known refrigerator are set, a freezing agent is frozen with electric power at night, cold air is generated using the freezing agent in the daytime, and the cold air is used for cooling.

  Traditionally, in midsummer outdoor stadiums and the like, spectators have used portable fans or refrigerated belts, cool sheets, etc., in order to prevent body temperature from rising. In addition, ice bags have been used to partially cool the affected area of patients in hospitals and the like.

  However, since the temperature is originally high in midsummer, it is not possible to obtain a satisfactory cold wind feeling with a fan. In the case where the affected area of the patient is partially cooled with ice cubes, it is difficult for the ice cubes to be continuously and freely cooled at any part of the affected area and at any angle.

  The problem to be solved by the present invention is that a cool fan feeling cannot be obtained with a portable fan or the like as an outdoor air conditioner in midsummer.

  Further, in a hospital or the like, in order to partially cool an affected part of a patient with ice, it is not possible to continuously cool the affected part at any angle at any part of the affected part.

  Therefore, the object of the present invention is to provide a feeling of cool air that is satisfactory even outdoors in the midsummer when the temperature is high, and to continuously cool the affected part at any angle and at any angle of the patient in a hospital or the like. An object of the present invention is to provide a cold air generator capable of generating a cold air.

The container unit has a U-shaped cryogen storage container having an opening on one side and a blower hole in the center of the other closed surface wall, and is provided in the cryogen storage container. And a plurality of misalignment prevention parts and a cryogen set and stored in the cryogen storage container so that an even space is maintained between the misalignment prevention parts and the container wall surface. It is a feature.

  According to the invention of claim 1, the air blown into the main body by the fan is cooled by the freezing agent set and stored in the main body, and this is supplied to the cooling through the cold air blowing pipe. As a result, a satisfactory cold wind feeling can be obtained even outdoors in midsummer.

  In addition, since the freezing agent is frozen in a freezer using electric power at night and stored in the main body as daytime cooling, it is excellent in economic efficiency.

  Further, since the entire apparatus can be downsized and portable, it is convenient in use.

  According to the second aspect of the present invention, which is dependent on the first aspect, the air blown from the air blowing holes of each partition wall spreads radially and regularly flows through the entire surface of each freezing agent without waste and is cooled. Therefore, the effect of cooling air is high, and a feeling of cold air that can be satisfied over a long time can be obtained.

  According to the invention described in claim 3 that depends on either one of claims 1 and 2, the storing and taking out of the freezing agent can be performed very easily.

  According to the invention of claim 4 subordinate to any one of claims 1 to 3, when the freezing agent is set and stored in each of the freezing agent storage chambers, both surfaces of the freezing agent and each partition wall and A uniform space is always maintained between the side walls, and the flow of wind is improved, and the blown air effectively flows over the entire surface of the freezing agent and is efficiently cooled.

  According to the invention of claim 5 subordinate to claim 1, a plurality of container units in which the main body is integrally polymerized, and a container unit in which the plurality of container units are housed and fixed in a closed state. Since it is configured as a double structure of the storage, when the main body is deformed or damaged, it is only necessary to replace the deformed or damaged portion without exchanging the entire main body, which is excellent in economic efficiency.

  In addition, the cold air generating apparatus according to the present invention can be attached to a stroller to give coolness to the child. There is a temperature difference of several degrees between the temperature around the upper body of the adult and the temperature near the ground on the paved road when walking under the hot summer heat, and the baby in the stroller is moving near the ground, Risk of causing dehydration. Therefore, with this cold air generator, if the cold air is used in a stroller rug or the like, an increase in body temperature is prevented, which is effective in preventing dehydration and the like. Ideally, it is desirable to cover a stroller to form a small room and circulate cold air through the room.
