Description

The present invention relates to a cooling/warming device for air conditioning fan clothes. The present invention was originally developed for the cooling of air conditioning fan garments and is generally used for that purpose. However, by changing the heat medium from a cooling agent to a heating agent, it can be easily changed for heating.

Whether indoors or outdoors, there are times when you have to work or exercise in a hot environment. In such a case, if severe conditions overlap, physical and mental abnormalities such as heat stroke may occur, and in the worst case, death may occur.

In order to prevent such a situation, in recent years, it has become common to provide a pocket in clothes to put a cooling agent in, or to attach an air-conditioning fan to the clothes. See the following patent documents.

However, simply adding a cooling agent causes the cooling effect to fade relatively quickly with the passage of time. Since the air-conditioning fan only takes in outside air and blows it into the clothes, it seems that the cooling effect is not sufficient in many cases.

On the other hand, in cold climates, it is common to use a warmer or wear an electric heating vest, so there is not much of a problem. However, it would be advantageous to have a device that could be used in common for cooling in summer and heating in winter by simply replacing the heat medium.

A switch 12 for selecting ON or OFF of the power supply is also provided.

Looking more closely, the device 1 has a housing 2, 3 which can be divided into two halves, 2 and 3, as shown in FIGS. As will be described later, the upper and lower parts 2 and 3 of the housing need to be separated to replace the cooling agent 8 inside, so they are joined with enough strength to separate them with the force of a finger. The lower halves 3 of the housings 2 and 3 are in contact with the skin of the user U, and the upper halves face outward.

Figures 5 and 6 show the formation of the upper housing half 2 of the device and Figures 7 and 8 show the formation of the lower half 3 of the device.

5(a) and 6(a) correspond to the upper half 2 of this apparatus, that is, the upper lid. The planar shape has an elliptical body 21 with short sidewalls 22 depending from the body profile. The left end of the body ellipse is slightly inwardly inclined to form an inclined portion 23 . The upper lid 2 is preferably made of a metal plate or a synthetic resin plate.

As shown in FIGS. 5(b) and 6(b), a metal sheet 24 (for example, aluminum, iron, copper, etc.) having excellent heat transfer properties is adhered to the inner surface of the top lid 2 . An exhaust fan 4 known per se is mounted on the aluminum sheet 24 of the inclined portion 23 .

FIG. 19 is a view of the inside of the device with the upper half (upper cover) opened. (a) is a front view of the upper cover as seen from the inside, and (b) is a front view of the main parts of the lower half of the device as seen from the inside.

The housing main body 21B is preferably made of a metal plate (aluminum, iron, copper, etc.) having excellent heat transfer properties, and aluminum is particularly preferred for molding. As shown in FIG. 18, it is preferable that the entire structure is double-walled with an inner wall 21B1 and an outer wall 21B2, and that the space between the walls is hollow except for support members. This is to increase the heat insulating effect of air. Such a double wall structure of the housing can also be incorporated in the above-described Embodiments 1 and 2 and the below-described Embodiments 4-6.

As shown in FIG. 19(b), the interior of the housing body 21B consists of a cooling agent storage chamber 28B on the right side and an intake/exhaust fan 46B on the left side. A partition 7B having a large opening for air circulation is provided between the two.

As the cold insulator 8B, a wide range of commercially available cold insulators can be adopted as long as the size and function are suitable.

As described above, one side of the cold insulating agent storage chamber 28B is the opening/closing door 26B.

The intake/exhaust fan 46B receives power from the power supply and rotates the fan via a motor. As the intake/exhaust fan 46B, a widely commercially available fan can be adopted as long as the size and function are suitable.

This cooling device 1B takes in outside air from the slit-shaped opening 35B on the right side by the intake and exhaust fan 46B, cools the air with the cold insulation material 8B while passing through the cold insulation agent storage chamber 28B, and blows off the cold air from the slit-shaped opening 25B on the left side. It is. The discharged cool air circulates while cooling the inner surface of the clothes, and goes out from the collar, cuffs, and lower part of the clothes. When the cooling effect of the cooling agent fades, open the opening/closing door and replace it with a new cooled cooling agent.

When the box-shaped cooling device 1B is worn on the human body, it does not matter which side, the front face (FIG. 16(c)) or the rear face (FIG. 16(e)), is the human body side. The selection may be made according to the preference of the user depending on whether or not it is better for the cold air outlet to be closer to the human body.
[Example 4-6]

Although not shown, by replacing the cooling agent in Examples 1-3 with an exothermic agent, a clothing warming device can be obtained. As an exothermic agent, for example, a commercially available body warmer can be used. In a commercially available body warmer, the exothermic agent is, for example, a powder mixture of iron powder, water, verculite, activated carbon, salts, etc., and generates moderate heat by reacting with oxygen in the air. It is also optional to use a sheet-like material formed from the mixed powder, or a sheet-like material holding the mixed powder. Of course, it is also possible to use other heating elements known per se.
