<P>PROBLEM TO BE SOLVED: To provide a light and inexpensive air conditioner for helmet, having a small size, easily being put on and off and capable of conditioning, heating and ventilating the helmet without applying any processing to all conventional helmets. <P>SOLUTION: A Peltier module 2 used for air conditioning and heating and fans 3, 4 of integrated heat sink are assembled to an air conditioning unit 5 and installed to a conventional helmet. An air passage 6 for air conditioning formed of a highly moisture-absorbing fiber material is fixed in the helmet. The fan 3 of the air conditioner and an inlet 8 of the air passage 6 for air conditioning are fixed and air for air conditioning are released from a large number of radially processed holes of the air passage for air conditioning. As a power source used for the air conditioning, a Ni-Cd battery 7 attached to the air conditioning unit 5. The electric power is reduced, as all parts are installed inside and outside of the helmet.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a helmet air conditioner that can be used in all commercially available helmets.

[0002]

2. Description of the Related Art Helmets worn during the operation of motorcycles and bicycles, during construction work, and during work at a guard man have no ventilation for releasing the heat inside, and may suffer heat stroke or heat stroke.

[0003]

The present invention eliminates the drawbacks of the prior art.

[0004]

According to the present invention, a fan is rotated by a nickel CADNICA battery mounted on the outside of a helmet to control the temperature inside the helmet by cooling and heating air and ventilation by an air conditioning unit equipped with a Peltier module. Is an air conditioner for a helmet that holds a.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below.

1 and 2 are structural views of the present invention. FIG. 3 is an explanatory view of the operation principle of the Peltier module.

FIG. 1 is a schematic sectional view of a helmet air conditioner. It consists of a helmet, an air conditioning air passage, and an air conditioning unit.

The air conditioning air passage fixed to the inside of the helmet takes in cooled or heated outside air from the air intake port 8 and discharges the outside air from a large number of holes radially arranged in the air conditioning air passage to cool the inside of the helmet. , Provide heating and ventilation.
The excess air is exhausted from the air exhaust port 9.

FIG. 2 shows an enlarged view of the air conditioning unit. A Peltier module 2 having heat exchangers 10 and 11 fixed to each of the upper joint portion 12 and the lower joint portion 13 and a fan integrated with a heat sheet for feeding the outside air intake and outside air discharge air into each passage are attached. Then, these air conditioning units are integrally attached to the outside of the helmet.

Two heat sink integrated fans are arranged in the air conditioning unit. Since the fan rotates in the same direction, one flows into the helmet for cooling and heating.
One is released into the atmosphere without entering the helmet.

A heat insulating material is used for the casing for the air conditioning unit. An air filter is attached to the rear end surface of the casing to prevent dust and dirt from entering the outside air when taking in the outside air with a fan. Also, install a power supply box on the side of the air conditioning unit and install a nickel CADNICA battery.

As shown in FIG. 3, the Peltier module 2 includes an N-type semiconductor Peltier element 14 and a P-type semiconductor Peltier element 15 at an upper joint 12 (copper electrode) and a lower joint 13.
It is formed by joining with (copper electrode). Connect power supply N
When a current is passed from the P-type semiconductor Peltier element 14 to the P-type Peltier element 15, the heat exchanger 10 absorbs heat and the heat exchanger 11 radiates heat. If a current is applied in the opposite direction, the heat exchanger 1
0 radiates heat, and the heat exchanger 11 absorbs heat. Due to these actions, the temperature of the heat exchanger 10 acting as (a) the heat absorption side is lowered by the cooling action, but the temperature drop of the heat exchanger 10 is mitigated by the outside air sent from the air filter by the fan 4, so the heat exchanger 10 It is possible to prevent the temperature drop. (B) Although the temperature of the heat exchanger 10 acting as the heat radiating side rises due to the heat generation effect, the temperature rise of the heat exchanger 10 is mitigated by the outside air sent from the air filter by the fan 4, so that the heat exchanger 10 is extremely heated. Temperature rise can be prevented.

By installing a switch capable of reversing the flow of current, the helmet air conditioner can be selectively used for cooling or heating.

If only the fan 3 is driven, it can be used for ventilation work.

The air-conditioning air passage is made of a highly hygroscopic fiber circular material and is radially formed as shown in FIG. 1, and has a large number of holes therein for discharging air for cooling / heating and ventilation.

FIG. 4 shows an electrical wiring diagram.

EFFECTS OF THE INVENTION The temperature inside the helmet of a person who is working in the hot sun or who wears a hat for a long time can be lowered, and the body can be protected from heat stroke and heat stroke. We also believe that the air conditioning unit attached to the helmet is lightweight and compact, which reduces air temperature loss and power consumption, and is convinced that it will be safer, more comfortable, and have the greatest effect in preventing accidents compared to general commercially available helmets. Also, it is convenient to carry, so it can be used anywhere.
