2. Description of the Related Art Conventionally, as this type of temperature control device,
There is one as described in JP-A-5-277020. FIG. 12 shows a conventional temperature control device described in the above publication.

In FIG. 12, the temperature adjusting device is a backrest portion 1.
A seat 3 for an automobile, which includes a seat 2 and a seat 2, a Peltier module 4 arranged in a lower space of the seat 3, and a main heat exchanger 5 connected to the Peltier module 4 for cooling or heating an air flow. And a waste heat heat exchanger 6 for exchanging waste heat into an air flow, an air flow blowout hole 8 for blowing out the air flow, which is provided on the front cover 7 of the seat on which the occupant of the backrest portion 1 and the seating portion 2 sits. The heat exchanger 5 communicates with the air flow outlet 8, and an air flow passage 9 provided inside the backrest portion 1 and the seating portion 2 for conveying the air flow to be blown out, and the waste heat heat exchanger 6 is discarded. It was composed of a waste heat air flow passage 10 for carrying a hot air flow, and a blower 11 for carrying an air flow to the main heat exchanger 5 and the waste heat heat exchanger 6 connected to the Peltier module 4.

Then, the Peltier module 4 and the blower 11 are driven during operation of the automobile, and in summer, the air flow carried by the blower 11 is cooled by the main heat exchanger 5 transferred by the Peltier module 4 to produce air. Transported in the flow passage 9,
It was blowing out as cold air from the airflow outlet 8. The waste heat air flow heated by the waste heat heat exchanger 6 transferred by the Peltier module 4 was blown as waste heat from the waste heat air flow passage 10. On the other hand, in winter, the airflow carried by the blower 11 is heated by the main heat exchanger 5 transferred by the Peltier module 4 and carried by the airflow passage 9, and the airflow outlet 8
It was blowing out as warm air. The waste heat air flow cooled by the waste heat heat exchanger 6 transferred by the Peltier module 4 was blown out as waste heat from the waste heat air flow passage 10. In this way, the back and hips of the occupant are cooled or heated to air-condition the seat.

As another conventional temperature control device,
There was a thing as described in Japanese Patent Publication No. 10-504977. FIG. 13 shows another conventional temperature control device described in the above publication.

In FIG. 13, the temperature control device is a seat 3
And an air channel 12 which is formed inside the seat 3 and is positioned in contact with the surface cover 7 of the seat to effectively cool or heat the seated occupant by heat conduction and circulates temperature-controlled air. A heat pump 13 having a Peltier module 4 in communication with the air channel 12 for cooling or warming the air, a control switch 14 for operating the device and at the same time selecting a heating or cooling mode of operation. A controller 15 that automatically adjusts the operation of the heat pump 13 to send the temperature-controlled air according to the heating or cooling operation performed, and the main heat that is connected to the heat pump 13 and selectively heats or cools the air. Unnecessary waste heat is removed from the exchanger 5, the main heat exchanger blower 16 that sends heated or cooled air, and the Peltier module 4. And because of the waste heat heat exchanger 6, it was composed of a waste heat exchanger fan 17 for sending air to the waste heat exchanger 6.

During operation, the Peltier module 4, the main heat exchanger blower 16 and the waste heat heat exchanger blower 17 are driven, and the airflow carried by the main heat exchanger blower 16 is transferred by the Peltier module 4. After being cooled or heated by the main heat exchanger 5, the air channel 12 is circulated, the surface cover 7 of the seat is cooled or heated, and after circulation, the air is returned to the main heat exchanger blower 16 again. The waste heat exchanger blower 17 blows air to the waste heat heat exchanger 6 and blows out the waste heat transferred from the Peltier module 4 to the waste heat heat exchanger 6. In this way, the back and buttocks of the occupant seated on the surface cover 7 of the seat 3 are cooled or heated by heat transfer by heat conduction to air-condition the seat.

[0008]

However, in the above-mentioned conventional device, when the vehicle is stopped during parking in summer and the seat temperature rises due to sunlight, the Peltier module 4 and the blower 11 are driven when restarted. Then, the airflow is cooled and conveyed to the airflow outlet 8, but the specific heat of the air is as small as about 0.29, and the temperature rises before reaching the airflow outlet 8, so that the seat 3 Surface cover 7
Had the problem that it could not be cooled. Further, a part of the airflow outlet 8 may be blocked by a human body, and the blocked airflow outlet 8 cannot blow a cooled airflow, so that part is uncomfortable. Had challenges. Further, since the air flow outlets 8 are provided at a certain interval, it is not possible to uniformly cool or heat all the areas of the seat surface. These are due to the fact that the main heat exchanger has only the function of cooling or heating the airflow with the heat of cooling or heating from the Peltier module.

Further, in the other conventional device described above, since the air circulates through the air channel 12 to cool the seat 3 by heat conduction, the unpleasant sensation of sweat or the like cannot be eliminated even if the human body is cooled. However, there was a problem that it was inferior in comfort. Further, since the air channel 12 actually becomes a passage, it is difficult to provide it in the entire area of the seat 3, and there is a problem that it is difficult to cool or heat the region between the air channels 12 and 12. In this case as well, this is because the main heat exchanger has only the function of cooling or heating the cooling or heating heat from the Peltier module.

The present invention solves the above-mentioned conventional problems. Even if the surface temperature of the seat rises due to solar radiation in the summer, when restarted, the temperature of the area in contact with the human body on the seat surface can be made substantially uniform in a short time. In addition to reducing the feeling of sweat and the like so that you can sit comfortably in the winter, the temperature of the area of the seat surface cover that contacts the human body is heated almost evenly in the winter so that you can sit comfortably. It is an object of the present invention to provide a temperature control device capable of cooling or heating by selecting either or both of convection and heat conduction by blowing hot and cold air on the surface cover.

[0011]

A temperature-controlled part that is heated to adjust the temperature is provided.

Accordingly, when the heat source cools or heats the heat conducting section and the convection section during operation, the heat conducting section conducts cooling heat or heating heat to cool or warm the temperature controlled section, and the convection section. The air blown by the blower is made into cold air or warm air by the heat from the heat source, and is blown out from the temperature controlled part to be cooled or heated. In this case, the heat conduction part and the convection part mutually cool or heat different places of the temperature controlled part. Therefore, the temperature controlled part is cooled or heated in different places by convection by the blowing of cold and warm air and heat conduction from the heat conducting part.

In this way, the temperature controlled part is cooled or heated in different places by convection due to the blowing of cold and warm air and heat conduction from the heat conducting part, so that, for example, the body part of the user in summer. Separately, place the heat conducting part in the place where it drops almost uniformly in a short time, remove sweat with wind,

Therefore, especially in summer, the cold air from the convection part can be selected. Can remove sweat and eliminate the feeling of stuffiness. Further, in the winter, when the heat is exchanged with warm air, the temperature rise is small and the warmth is weak, but the heat conduction in the heat conducting portion allows the temperature rise to be large and the warmth is increased to improve the comfort.
