Abstract

The present invention provides a cooler and a blowing device using the cooler for a human body, with which coolant is employed to effectively cool down the target object to be cooled. Because of the cooler 40, the coolant 2 can be used to cool down the air inhaled by a blower of the blowing device for human body. Therefore, the air cooled down by the cooler 40 is discharged out from various wind guide pipes 30 to increase the cooling effect for the human body. The cooler 40 comprises: a heat insulation cooler body 41 for storing the coolant 2 in an extracting and inserting manner; and a heat conduction member 42 for performing heat exchange on the coolant 2 inside the cooler body 41 and the air outside the cooler body 41. Because the cooler 40 is installed to the external side of the cooler 20, it is able to cool down the air by a compact and simple structure. Furthermore, the coolant 2 only cools down the external air that comes into touch with the heat conduction member 42, and thus the cooling capability of the coolant 2 can be maintained for a long time.

Description

Cooling device and human air supply device using the same

The present invention relates to a cooling device for effectively cooling a cooling object by a cold preservation agent, and a human body air blowing device using the same.

In recent years, it has been proposed that air is supplied from a designated installation place away from the human body, such as an electric fan, and the wind is provided to the human body by carrying the blower. For example, the patent document 1 (Japanese Patent Laid-Open Publication No. 200554299) discloses that a blower is provided in the vicinity of the waist of the garment, and the outside air is introduced into the inside of the garment, and the cooled clothes that introduce air are discharged from the cuff and the collar. Further, for example, Patent Document 2 (Japanese Laid-Open Patent Publication No. 2013-36410) discloses a person in which a blower is suspended from a head by a headband and air is blown from a blower toward a face. These devices are highly convenient because they can be supplied with air regardless of where they are, and are particularly suitable for preventing heat stroke.

However, in Patent Document 1, it is necessary to form a hole in the clothes in order to provide a blower for introducing the outside air, in other words, since it is necessary to use special clothes, it cannot be applied to existing clothes. As a result, the problem arises that the cost increases and the user cannot wear the clothes that are preferred. Such problems are particularly important, for example, at construction sites. That is, since the clothes on the construction site need to have various special functions, or the marks are exclusive to the operator, and the clothes need to be changed at each site, the cooling clothes described in Patent Document 1 are expensive and are required to cope with all of them. Some of the questions asked.

Further, in Patent Document 2, although the air blower can only be hung from the head regardless of the clothes, it is difficult to stably provide air supply in a use form in which the body is required to constantly move. Such problems are particularly important, for example, at construction sites. Further, in such a field work, there is a possibility that the blower or the headband may hook or touch an object around the work site, and it is difficult to ensure sufficient safety.

Therefore, the applicant of the present invention has proposed a human air supply device for delivering air to a human body, which comprises: a blower disposed on the back side of the human body; and a pair of left and right air guide tubes, which are connected from the blower outlet through the shoulder and the head of the human body. The side portion is formed to extend to the front of the human body; and the base member is provided with a blower and each air guiding duct; the air can be discharged from the discharge hole provided in each air guiding duct toward the human body.

When the air blowing device for a human body is used, since the air guiding duct has a shoulder-hanging structure, it is possible to stably supply air and to wear the existing clothes, and therefore has an advantage that it can be constructed at a low cost.

Since the air supply device for human body can discharge the air of the suction blower from the air duct, the air of the same temperature around the air blower is blown to the human body. Therefore, for example, when the ambient temperature is high at a construction site in the summer, if the air discharged from the air duct is cooled and the air is blown to the human body, the human body cooling effect can be improved. At this time, if the cooling device of the refrigeration circuit is used, the size of the device is increased, and the cooling capacity of the electronic cooling element such as a Peltier element is insufficient. Therefore, if a cold-preservable refrigerant such as a refrigerator is used, the cost is low, and the air can be cooled by a simple structure.

However, in order to cool the air by the refrigerant, for example, when designing a blower unit that houses the blower and the refrigerant, the apparatus is enlarged and the weight is increased, so that it is not suitable for human body wear. In addition, if the refrigerant is installed outside the blower, the air intake of the blower is cooled by the cooling agent. In the case of near air, weight reduction can form a simple structure. However, since the substantially entire surface of the cooling agent is in contact with the outside air for heat exchange, when the air in the vicinity of the air suction port of the blower is cooled by the refrigerant, the air sucked into the blower is only in contact with a part of the surface of the refrigerant. Therefore, there is a problem in that the cooling efficiency of the cooling agent is poor, and the cooling ability of the cooling agent is lowered in a short time.

The present invention has been made in view of the above problems, and an object thereof is to provide a cooling device for effectively cooling a cooling target object by a cold preservation agent and a human body air blowing device using the same.

In order to achieve the above object, the cooling device of the present invention includes: a heat insulating cooling device body that can discharge the cold retaining agent in a pumped manner; and a heat transfer member that fixes the cold retaining agent in the body of the cooling device and the outside of the body of the cooling device The object to be cooled is subjected to heat exchange.

Further, the air blowing device for a human body according to the present invention includes: a pair of left and right air guiding ducts that are formed to extend from the back side of the human body to the front side of the human body via the shoulder and the head side, and are provided with a discharge hole for discharging air; And a blower that sends air to each of the air ducts; and the cooling device is mounted on the outside of the blower, and the air outside the cooler body is cooled by the heat transfer member of the cooling device, and is sucked by the blower.

Thereby, the air cooled by the cooling device is discharged from the respective air ducts, and the cooling effect on the human body is high. At this time, since the portion other than the heat transfer member of the cooling agent of the cooling device is covered by the heat insulating cooler body and is not heat-exchanged with the outside air, only the outside air that is in contact with the heat transfer member is cooled by the refrigerant.

According to the present invention, even when the ambient temperature is high, for example, in a summer construction site, since the air cooled by the cooling device is discharged from each air duct, the cooling effect of the human body can be improved, and thus it is effective for preventing, for example, heat stroke. At this time, it can be constructed by being light and simple. The air is cooled, and only the outside air that is in contact with the heat transfer member can be cooled by the refrigerant, so that the cooling ability of the refrigerant can be maintained for a long time.

The above and other objects, features, and advantages of the present invention will be apparent from the description and appended claims.
