Description

Vehicle steering wheel cold or warm air blowing system {Cold or Warm air blowing system through vehicle steering wheel}

The present invention relates to a vehicle handle cold/warm air blowing system, and more particularly, blows cold air discharged through a vehicle air conditioner or warmth discharged from a heater to a driver through a vehicle handle, and the vehicle handle holds the driver's hand to an appropriate temperature It relates to a vehicle steering wheel cooler and air blower system to keep it cool.

In general, the interior of a vehicle must maintain optimum temperature and humidity for a comfortable indoor environment for passengers in the vehicle regardless of external climatic conditions.

In the summer heat, the interior temperature of a car exposed to direct sunlight often overheats to the point of hearing the news of a gas explosion, so an air conditioner is essential to keep the temperature inside the vehicle cool.

Also, in winter, a heater is essential to warm a vehicle for a warm and cozy indoor environment in severe cold.

The vehicle air conditioner serves to reduce the temperature of the room by supplying cool air to the room using the phenomenon of absorbing ambient heat when the liquid evaporates. Looking at the overall configuration of such an air conditioner, the compressor compresses the vaporized high-temperature refrigerant into a high-temperature and high-pressure gas state, and the high-temperature and high-pressure refrigerant compressed by the compressor is liquefied by the air sucked from the front according to the rotation of the cooling fan. It consists of a condenser, an expansion valve that rapidly expands a high-pressure liquid refrigerant into a low-temperature/low-pressure refrigerant, and an evaporator that cools the surrounding air by evaporating the low-temperature refrigerant. The air cooled while passing through the evaporator is supplied to the interior of the vehicle by a blower.

However, as the airbag is mounted in the center of the steering wheel and the remote control for audio is attached, there is a problem that acts as a barrier to the flow of cold or warm air between the air conditioner and the driver. That is, although the driver (driver) is always located in the driver's seat, although there are often empty seats in the passenger seat or the rear seat, cold or warm air is supplied without obstacles to the passenger seat or the rear seat, whereas the driver is always on board In the driver's seat, the steering wheel acts as an obstacle, so there was a problem that cold or warm air was not transmitted properly.

As a part of solving such a problem, in Patent Publication No. 10-2011-0133536 (published date: December 13, 2011) cited herein as a prior document, with reference to FIG. 1 , an air conditioner mounted on a vehicle and A cold and hot air supply pipe 3 is provided so that some of the cold and hot air generated from the air conditioner and heater is supplied to the handle 1 by being connected to the heating and cooling system 2 such as a heater, and the inside of the handle 1 is formed in a hollow state. A plurality of discharge holes 11 are drilled radially on the outer circumferential surface, but the cold and hot air supply pipe 3 and the handle 1 are connected with a flexible coil-type hose 4 to rotate the handle clockwise or counterclockwise We are proposing a technology that enables the stable supply of hot and cold air even in the process of cooling.

However, in the above-described prior art, there is no disclosure of a ventilation system in which hot and cold air is transmitted from the vehicle air conditioning system to the vehicle steering wheel.

Since the steering wheel for a vehicle is in charge of an important function of steering, there is a risk of causing a major accident if the hot/cooler pipe that connects to the steering wheel is tangled with the steering shaft.

In addition, there is a concern that the hot/cooler piping provided around the steering shaft may generate noise by colliding with the steering shaft or peripheral devices.

In addition, there is a risk that the life of the pipe may be shortened due to the twisting movement according to the left and right rotation of the handle or it may be damaged by colliding with other peripheral devices.

Since the above-described steering shaft through-hole bearing 600 is screwed into the steering shaft through-hole 510 to eliminate the play of the steering shaft 400 , it is possible to prevent damage due to noise or vibration, and the steering shaft 400 . It has the effect of enabling smooth rotation of

Meanwhile, referring to FIG. 3 , in the vehicle handle 100 , the steering wheel internal vent pipe 110 is formed in a hollow shape so that cold or warm air can flow along the circular edge of the steering wheel, and the steering wheel internal vent pipe 110 and the vehicle air conditioning The handle fastening part 120 connected to the hot or cold air pipe 300 through which warm or cold air from the system flows, and the cold air or warmth flowing through the handle inner vent pipe 110 are radially distributed on the front part of the handle so that it is discharged to the driver's seat. It is formed to include the formed vent 130 .

As a result, it is possible to directly discharge hot and cold air to the user through the ventilation holes 130 dispersed throughout the steering wheel, thereby enhancing the effect of in-vehicle air conditioning for the driver.

On the other hand, according to another preferred embodiment of the present invention, by forming the handle of a metal material including at least one of aluminum, aluminum alloy, brass, and stainless steel, there is an effect of increasing the effect of cold and heat transmitted to the driver. That is, by manufacturing the handle made of a metal material with high thermal conductivity, such as aluminum, aluminum alloy, brass, or stainless steel, it is possible to increase the transfer efficiency of cold or warm air.
