Abstract

PURPOSE:To moderate uncomfortableness of sultry or cold room to be felt immediately after a person gets on a car by having a cooling (or heating) face of a Peltier element occupy an area, especially, to which a human body is easy to access, inside a car wherein an air conditioner is not fully operated yet because an engine is just started, so as to locally and quickly cool or heat said area. CONSTITUTION:At the upper face of an arm rest framework 8 attached to a door panel B, an arm rest face has an open part 8a from which the heat transferring face 2 of a Peltier element 1 is exposed. A Peltier element heat source body 1 wherein the Peltier element 1 has the heat transferring face 2 and a radiating fin 3 joined on the opposite faces thereof is mounted to a cylindrical body 10 which can be turned inside a bellow part of an arm rest. When the heat source body is used, the cylindrical body is turned clockwise until a detent 12 shown on the drawing pushes a power opening/closing microswitch 13 to turn on a power. The action of the cylindrical body 10 is then restraint by the engagement of the ratchet 15 of a stopper 14 into a dent 16. Heat from the heat source body circulates inside the hollow arm rest and is then radiated to the outside of a car after passing through ventilation holes 8b and 8c.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field 1] The present invention relates to a device for controlling the temperature of a small, limited area inside a vehicle interior, such as the surface of an armrest of an automobile.

[Prior Art 1] Modern automobiles have reached a level that is practically satisfactory in terms of their engine and suspension parts, which are responsible for their original function of moving people and goods quickly and safely, and in the future they will For passenger cars, improving ride comfort and interior atmosphere is becoming an important goal.

For example, in Japan, where the climate fluctuates significantly between the four seasons, interior materials can become extremely hot when you get into a car parked in the hot sun, and can even become uncomfortably cold in the depths of winter. It is something that you can feel.

In such cases, if heat can be adjusted locally, especially in areas that come into contact with the human body, the above-mentioned goal of effort should be achieved. However, I have not yet seen or heard of such an idea.

OBJECT OF THE INVENTION] The purpose of the present invention is to provide local air conditioning to areas that are particularly likely to touch the human body and feel unpleasantly hot or cold during mid-summer or mid-winter, when the vehicle interior air conditioner is not fully functioning immediately after startup. The goal is to provide a way to adjust the temperature.

[Structure of the Invention] The dual-use temperature control device of the present invention is configured such that at least a portion of the surface of the part that directly comes into contact with the human body of an occupant inside the vehicle is occupied by a cooling (or heat generating) surface of a Peltier element. .

According to a preferred embodiment of the present invention, the heat generating (or cooling) side of the Peltier element is placed on the inner wall surface of the wall portion (heat transfer surface) made of a good thermal conductor of the rotatable cylindrical body including the cylindrical wall portion made of a good thermal conductor. The heat transfer surface of the heat source body having heat dissipation fins attached thereto is brought to a temperature-controlled area by rotating the cylindrical body, and is configured to be able to be removed from this area, and the cylindrical body is a switch mechanism that operates in conjunction with the movement of the cylinder for supplying operating power to the Peltier element when the cylinder wall made of a thermally conductive material is rotated and brought to a temperature-controlled area; When the cylindrical body and a concave hole or other engaged member provided in a part of the body are brought to the temperature adjustment region, the cylindrical body is heated by the action of an electromagnet that is energized in conjunction with the movement of the cylindrical body. A donkey or other engaging member for stopping the cylinder that is engaged with the engaging member is attached, and by separating the center of gravity of the rotatable cylinder from the cylinder shaft of the cylinder, the transmission is reduced when energized. The structure is such that the weight of the cylindrical body is balanced and the cylindrical body stops rotating at a position where the heating surface is brought outside the range of temperature control.

[Effects of the Invention] The temperature control device for a vehicle according to the present invention has the following effects.

5-a) In mid-summer or cold weather, immediately after the engine has been started, the air-conditioning system is not fully functioning in the vehicle interior, so avoid touching areas that are particularly easily touched by the human body, such as the armrest armrests or headrests. Since it can be quickly cooled or heated, the discomfort of feeling hot or cold immediately after boarding can be alleviated to a considerable extent.

In addition to cooling or warming the human body, the device of the present invention can also be used to store items that are sensitive to temperature changes by incorporating them into an insulating container, thereby cooling or heating those items without relying on air-conditioning equipment. can be protected from the effects of heat.

[Example] ``Next, a temperature control device for a vehicle according to the present invention is shown in the drawings, and will be explained based on an example.

The front and inner surfaces are covered with padding material 9.

The Peltier element heat source body is constructed by joining a heat transfer surface 2 and a heat radiation fin 3 to both sides of a Peltier element 1, respectively. It is assembled to this cylindrical body 10 in such a way that the heat transfer surface 2 is replaced. This figure shows a state in which the Peltier element heat source is not in use, and the heat source is immersed in the inner space of the armrest 6 and protected. A portion 10a of the cylindrical body wall exposed to the surface of the armrest is covered with a pad material 11 so as not to impair the feel and appearance. When you want to use a Peltier element heat source,
