Description

[Detailed Description of the Invention] The present invention relates to a portable heating and cooling device used when working outdoors in hot or cold weather, watching outdoor sports, or driving a motorcycle.

Traditionally, for example, when working outdoors under the scorching sun, workers put a wet towel on their foreheads and bodies to remove the heat, or put a warmer in their pockets to keep warm when it's cold. The device did not yet exist.

In view of these inconveniences, the purpose of the present invention is to provide a simple and portable device that can cool or heat various parts of the body, and its main structure is small. A ventilation path having an air intake port at one end and an air discharge port at the other end and equipped with a blower fan is formed in the housing, and a heat medium storage chamber surrounding the ventilation path is formed, The air blower, which is located away from the body and has a plurality of discharge holes, communicates with the air discharge port through a tube.

An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a small casing made of synthetic resin or other material. Inside the casing 1, for example, as shown in the figure, a pipe bent in a substantially spiral shape is provided, and the inside of the pipe is formed into a ventilation passage 2, with one end thereof being When an enlarged ventilation passage 2a is formed and a motor 4 having a blower fan 3 is provided in the enlarged ventilation passage 2a, the tip of the enlarged ventilation passage 2a is formed as an air intake port 5, and the other end of the ventilation passage 2 is The root of a tube 19, which will be described later, is formed into an air outlet 6 which can be detachably attached. Reference numeral 7 indicates a storage chamber for a heat medium for cooling or heating, and the storage chamber 7 is connected to the housing 1.
A heat insulating layer 8 is interposed therebetween, and the ventilation path 2 is formed within the housing chamber 7 through a tube wall having good thermal conductivity. 9 is code 1 from external power supply 10
1 a connector for connecting 1; 12 a cord for connecting between the connector 9 and the motor 4; 13 a cord for connecting the connector 9 and the motor 4;
1 is an operation switch for rotating or stopping the fan 3 or varying the rotation speed; 14 is a filter; 1
5 is an opening for taking in and taking out the heat medium; 1
6 indicates the plug of the opening 15.

In this way, a sponge may be placed in the storage chamber 7 in advance and soaked with cooling water, or water mixed with ice may be directly poured into the sponge, or the storage chamber 7 may be divided into double chambers and one of the chambers may be divided into two chambers. A cooling heat medium is accommodated in the storage chamber 7 by, for example, placing dry ice in one chamber and water in the other chamber. When cooling the upper body of a person working under the scorching sun, a large number of discharge holes 1 are installed inside clothes A or underwear as shown in Figure 3.
Air blower 1 consisting of a ring-shaped tube having 7
8 with a removable adhesive or the like, and the tube 19 from the air blower 18 is tied to the air outlet 6, and the housing 1 and power source 10 are secured to belt B, for example, with a locking tool. Or carry it over your shoulder like a handbag. When the blower fan 3 is rotated by operating the switch 13, the air from the suction port 5 is cooled by the cooling heat medium in the air passage 2 and passes through the tube 19 to the discharge hole 1 of the blower 18.
7, so workers do not feel hot even under the scorching sun and feel refreshed, increasing work efficiency. still,
If the air conditioner is too effective, you can change the switch 13 to "weak".

FIG. 4 shows a case where the forehead is cooled, and a ventilation device 18 consisting of a curved tube having a large number of discharge holes 17 is shown in FIG.
The ventilator 18 is fixed to the headband 20 so as to be in front of the forehead, and can be used as a substitute for an ice pack when a person has a high fever due to illness, for example.

FIG. 5 shows a case in which a helmet is modified to form a ventilation device 18, an inner shell 18b is provided inside an outer shell 18a of the helmet, and a ventilation chamber 18c is formed between the two.
and a large number of discharge holes 17 are formed in the inner shell 18b, a tube 19 is connected to the ventilation chamber 18c, and the cooled air is discharged through the discharge holes 1.
7 to allow comfortable driving of a motorcycle under the scorching sun, for example.

Furthermore, by changing the shape of the ventilator 18 depending on sweaty areas such as armpits, it can be applied to cooling various areas.

Furthermore, when the above-mentioned device is used for heating in cold weather, a long-lasting heating medium may be placed in the accommodation chamber 7. The ventilation path 2 is not limited to the spiral shape as in the embodiment described above, but may be formed into any other shape such as a meandering shape, and the power source 10 may be any suitable type, such as a dry battery or a battery. Furthermore, if something such as ice water is stored in the storage chamber 7, the housing 1 can be used as a water bottle in case of an emergency.

In addition, if an on-off valve 20 is provided on the side wall of the expanded ventilation passage 2a, when gas is used as a heat medium,
When the valve 20 is opened at the beginning of use, the heat medium gas is sucked together with the outside air by the fan 3, and the cooled or heated air is immediately discharged from the discharge hole 17 of the blower 18. Furthermore, if the tube 19 is connected to the air discharge port 6 through a plurality of connecting fittings, it is possible to cool and heat a plurality of locations at the same time. Furthermore, if a mask is used as the blower 18 and a layer of activated carbon is provided at the filter 14, it can be used as a smoke-proof mask in case of a fire or the like. As described above, according to the present invention, the housing that blows cooled or warmed air can be attached to a band, etc., and the blower that blows out the air can be attached to the body or clothes as appropriate, making it extremely convenient to carry. Therefore, it is possible to work outdoors, watch sports, drive a motorcycle, etc. comfortably in the hot sun or in cold weather, and the structure is simple and can be obtained at low cost.
