[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temperature adjusting device used for a seat or the like for cooling or heating a human body.

[0002]

2. Description of the Related Art Conventionally, as this type of temperature control device,
There was a thing as described in Unexamined-Japanese-Patent No. 5-277020. FIG. 10 shows a conventional temperature control device described in the above publication.

In FIG. 10, 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 one as described in Japanese Patent Publication No. 10-504977. FIG. 11 shows another conventional temperature control device described in the above publication.

In FIG. 11, 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 lowering the feeling of sweat and making it comfortable to sit in, in winter the temperature of the surface cover of the seat in contact with the human body is heated almost evenly so that you can sit comfortably. .

[0011]

In order to solve the above-mentioned conventional problems, the temperature control device of the present invention comprises a heat source for cooling or heating, and a heat conducting portion for diffusing the heat from the heat source by heat conduction. , A blower that blows air, a convection section that cools the air blown by the blower with the heat from the heat source or blows it out as mere air, and a temperature controlled by the heat conduction section and the convection section And a section.

Thus, 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. Therefore, the temperature controlled part is cooled or heated by both convection due to the blowing of cold and warm air and heat conduction from the heat conduction part.

In this way, the temperature controlled portion is cooled or heated by both convection due to the blowing of cold and warm air and heat conduction from the heat conducting portion, so that heat conduction from the heat conducting portion is achieved especially in summer. It can be lowered almost uniformly in a short time, and sweat from the convection section can be removed to eliminate the discomfort. Furthermore, even in winter, the seats can be air-conditioned comfortably with almost even heating.

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. Therefore, the temperature controlled part is cooled or heated by both convection due to the blowing of cold and warm air and heat conduction from the heat conduction part.

In this way, the temperature controlled portion is cooled or heated by both convection due to the blowing of cold and warm air and heat conduction from the heat conducting portion, so that heat conduction from the heat conducting portion is achieved especially in summer. It can be lowered almost uniformly in a short time, and sweat from the convection section can be removed to eliminate the discomfort. Furthermore, even in winter, the seats can be air-conditioned comfortably with almost even heating.

It is cooled or heated by both conduction.

In this way, the temperature control part can choose to blow cold / warm air by the convection part and heat conduction from the heat conduction part by only at least one side. 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.

According to a third aspect of the present invention, heat sources are provided in the heat conducting section and the convection section, respectively, and the heat conducting section and the convection section correspond to the respective heat sources. If you select only, the heat conduction part heat source cools or heats only the heat conduction part, and the heat conduction part conducts cooling heat or heating heat to cool or heat the temperature controlled part and adjust it to the set temperature. .

When only the convection section is selected, the convection section heat source cools or heats only the convection section, and the convection section turns the air blown by the blower into cold air or warm air from the heat source and outputs it from the temperature controlled section. Blow out and control to the set temperature.

When both the heat conduction section and the convection section are selected, the heat conduction section heat source cools or heats the heat conduction section and the convection section heat source, and the heat conduction section conducts cooling heat or warming heat. The temperature controlled part is cooled or heated, and the convection part turns the air blown by the blower into cold air or warm air with the heat from the heat source and blows it out from the temperature adjusted part. It is cooled or heated by both heat conduction from the heat conduction part.

In this way, the heat sources are provided in the heat conducting section and the convection section, respectively, and are adapted to the operation by the heat conducting section and the convection section respectively, so that the selection can be facilitated.

According to the fourth aspect of the present invention, the heat source is common to the heat conducting section and the convection section. When only the heat conducting section is selected, the heat source cools or heats the heat conducting section and the convection section. Since the convection unit does not exchange heat with cold air or warm air by stopping the blower, the heat-conducting unit cools or heats the temperature-controlled unit to adjust it to the set temperature.

When only the convection section is selected, the heat source does not cool or heat the heat conduction section, and the convection section turns the air blown by the blower into cold air or warm air by the heat from the heat source from the temperature control section. Blow out and control to the set temperature.

When both the heat conduction section and the convection section are selected, the heat conduction section heat source 28 cools or heats the heat conduction section and the convection section heat source, and the temperature controlled section performs convection by blowing cold and warm air. It is cooled or heated by both heat conduction from the heat conduction part.

In this way, the heat source is shared by the heat conducting section and the convection section, and the heat conduction section and the convection section are adapted to the respective operations, so that the structure can be simplified.

According to a fifth aspect of the present invention, when the temperature of the temperature controlled part is controlled by the heat conducting part,
When a common heat source is operated and a cool / hot air volume adjusting means is provided to prevent cool / hot air from being conveyed from the convection section to the temperature controlled section, if only the heat conducting section is selected, the heat source will be the heat conducting section. And the convection section is cooled or heated, and the convection section is operated by the blower to blow out the cold and warm air, but the cold and warm air volume adjusting means prevents the conveyance. Therefore, the temperature controlled part can be cooled or heated only by the conduction part and adjusted to the set temperature.

In this way, the heat source is common to the heat conducting section and the convection section, and even if the heat conducting section and the convection section are cooled or heated, the temperature controlled section is constituted by only the conduction section with a simple structure. Can be cooled or heated.

According to the sixth aspect of the invention, when the temperature of the temperature controlled part is adjusted by the convection part, the common heat source operates and heat is not transmitted from the heat source to the heat conducting part. If only the convection section is selected by providing the heat transfer amount adjusting means, the heat source prevents the heat source from cooling or heating the heat conducting section, and the convection section causes the air blown by the blower.

According to the eighth aspect of the present invention, the heat source is configured by using the Peltier module, and when the Peltier module is operated, the Peltier module cools or heats the heat conducting section and the convection section in terms of cooling or heating. . The heat conduction part conducts cooling or heating heat of the Peltier module to cool or heat the temperature controlled part, and the convection part cools or warms the air blown by the blower with the cooling or heating heat of the Peltier module. It is blown out from the temperature controlled part and cooled or heated. Therefore, the temperature controlled part is cooled or heated by both convection due to the blowing of cold and warm air and heat conduction from the heat conduction part. Further, since the blower also drives the air to blow air on the surface of the Peltier module where heat is exhausted, it is also sent as waste heat.

When cooled or heated, the heat conduction part conducts cooling or heating heat to cool or heat the seat cover as the temperature controlled part, and the convection part cools the air blown by the blower with the heat from the heat source. Hot air is blown out from the seat cover as a temperature-controlled part to be cooled or heated. Therefore, the seat cover as the temperature controlled portion is cooled or heated by both convection due to blowing of cold and warm air and heat conduction from the heat conducting portion.

In this way, since the seat cover as the temperature controlled portion is cooled or heated by both convection due to the blowing of cold and warm air and heat conduction from the heat conduction portion,
In the summer, the heat from the heat conducting portion can be reduced almost uniformly in a short time, and the wind from the convection portion can remove sweat and eliminate the feeling of discomfort. Furthermore, even in winter, the seats can be air-conditioned comfortably with almost even heating.
