Abstract

PROBLEM TO BE SOLVED: To eliminate a feeling of discomfort caused by a seat temperature increased by solar radiation during parking in summer and kept high during later driving. SOLUTION: A Peltier module 20 is designed to provide a heat exchange with cool or warm air and a heat exchange with a thermally conductive sheet 31 and to cool or warm a seat face cover 28 via both convection by a blow of the cool or warm air and thermal conduction from the thermally conductive sheet 31. The thermally conductive sheet 31 is also cooled or warmed. The thermally conductive sheet 31 cools or warms the seat face cover 28 via thermal conduction, and the cool or warm air is conveyed to the seat face cover 28 from which it is blown out. The seat face cover 28 is thus cooled or warmed via both convection by the cool or warm air and thermal conduction from the thermally conductive sheet 31, to thereby cool or warm a region on which an occupant sits substantially evenly in a short time and, especially in summer, improve comfort by eliminating stickiness with sweat.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat air conditioner capable of cooling or heating a seat.

[0002]

2. Description of the Related Art Conventionally, as this type of seat air conditioner, there has been one described in Japanese Patent Application Laid-Open No. Hei 5-277020. FIG. 6 shows a conventional seat air conditioner described in the above publication.

[0003] In FIG. 6, a seat air conditioner includes a backrest 1.
And a seat 3 for a vehicle comprising a seat 2, a Peltier module 4 disposed in a space below 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 provided on the front cover 7 on which the occupant of the backrest 1 and the seating portion 2 sits and blows out the air flow;
An air flow passage 9 communicated from the main heat exchanger 5 to the air flow outlet 8 and provided inside the backrest portion 1 and the seating portion 2 for conveying the blown air flow, and a waste heat heat exchanger 6 It was composed of a waste heat air flow passage 10 for conveying the waste heat air flow, and a blower 11 for conveying the air flow to the main heat exchanger 5 and the waste heat heat exchanger 6 connected to the Peltier module 4.

[0004] The Peltier module 4 and the blower 11 are driven during operation of the automobile. In summer, the air flow conveyed by the blower 11 is cooled by the main heat exchanger 5 which is transferred by the Peltier module 4 and the air is cooled. Conveyed in the flow passage 9,
The air was blown out from the air flow outlet 8 as cold air. The waste heat air flow heated by the waste heat exchanger 6 transferred by the Peltier module 4 was blown out from the waste heat air passage 10 as waste heat.

On the other hand, in winter, the air flow conveyed by the blower 11 is heated by the main heat exchanger 5 transmitted by the Peltier module 4, conveyed by the air flow passage 9, and It was blowing out as warm air. The waste heat air flow cooled by the waste heat exchanger 6 transferred by the Peltier module 4 was blown out from the waste heat air passage 10 as waste heat. In this way, the seat is air-conditioned by cooling or heating the back and buttocks of the occupant.

As another conventional heat transfer device for a seat, there has been one disclosed in Japanese Patent Publication No. 10-504977. FIG. 7 shows a conventional seat air conditioner described in the above publication.

[0007] In FIG.
And an air channel 12 formed inside the seat 3 and positioned in contact with the front surface cover 7 of the seat to effectively cool or heat the seated occupant by heat conduction and circulating temperature-controlled air. A heat pump 13 communicating with the air channel 12 and having a Peltier module 4 for cooling or warming the air, a control switch 14 for operating the device and at the same time selecting operation in a heating or cooling mode; A controller 15 that automatically regulates the operation of the heat pump 13 to send air temperature-controlled according to the heating or cooling operation performed, and a main heat that is connected to the heat pump 13 and selectively heats or cools the air. The exchanger 5, a main heat exchanger blower 16 that sends heated or cooled air, and an unnecessary waste heat from the Peltier module 4. And because of the waste heat heat exchanger 6, we were 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 air flow carried by the main heat exchanger blower 16 is transferred by the Peltier module 4. After being cooled or heated in the main heat exchanger 5, the air channel 12 is circulated to cool or heat the surface cover 7 of the seat. After the circulation, the air returns to the main heat exchanger blower 16 again. The waste heat exchanger blower 17 blows the waste heat heat exchanger 6 and blows out 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 front cover 7 of the seat 3 are cooled or heated by heat transfer by heat conduction to perform air conditioning of the seat.

[0009]

However, in the above-described conventional apparatus, when the vehicle is stopped during parking in summer and the seat temperature rises due to insolation, when the vehicle is restarted, the Peltier module 4 and the blower 11 are driven. Then, the air flow is cooled and conveyed to the air flow outlet 8, but the specific heat of the air is as small as about 0.29, and the temperature rises before reaching the air flow outlet 8, so that the seat 3 Surface cover 7
Has a problem that it cannot be cooled in a short time. In addition, a part of the air flow outlet 8 may be closed by a human body, and the closed air flow outlet 8 cannot discharge the cooled air flow, so that the part has discomfort. Had issues. Further, since the air flow outlets 8 are provided at certain intervals, the entire area of the seat surface cannot be uniformly cooled or heated.

In the above-mentioned conventional device, since the air is circulated through the air channel 12 to cool the seat 3 by heat conduction, even if the human body is cooled, the sense of discomfort such as sweat cannot be eliminated. However, there is a problem that the comfort is inferior. Furthermore, since the air channel 12 actually becomes a passage, it is difficult to provide the air channel 12 over the entire area of the seat 3, and there is a problem that the area between the air channel 12 and the air channel 12 is difficult to cool or heat.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems, and reduces the temperature of the area of the seat surface in contact with the human body at the time of re-driving almost uniformly in a short period of time, and also eliminates the feeling of discomfort such as sweat, thereby providing a comfortable environment. It is an object of the present invention to provide a seat air-conditioning system that enables a user to sit comfortably while comfortably sitting by heating a temperature of a region in contact with a human body on a seat surface almost uniformly in winter.

[0012]

In order to solve the above-mentioned conventional problems, an air conditioner for a seat according to the present invention uses a Peltier module to exchange heat with cold and hot air and heat with a heat conductive sheet, thereby reducing the seat surface. The cover is configured to be cooled or heated by both convection by blowing cold and hot air and heat conduction from the heat conductive sheet.

[0013] Thus, in summer, when the operation is performed, the supplied air flow is heat-exchanged to cool air by the Peltier module, and at the same time, the Peltier module also exchanges heat with the heat conduction sheet to cool it. The cooled heat conductive sheet cools the seat surface cover by heat conduction. Further, the cool air is conveyed to the seat surface cover and blows out from the seat surface cover. Therefore, the seat surface cover is cooled by both convection due to blowing of cold air and heat conduction from the heat conductive sheet.

In winter, when the air conditioner is operated, the supplied air flow is exchanged with warm air by the Peltier module, and at the same time, the Peltier module also exchanges heat with the heat conductive sheet to heat it. The heated heat conductive sheet heats the seat surface cover by heat conduction. Further, the warm air is conveyed to the seat surface cover and blows out from the seat surface cover. Therefore, the seat surface cover is heated by both convection due to the blowing of warm air and heat conduction from the heat conductive sheet.

[0015] In this manner, the seat surface cover is cooled or heated by both convection due to the blowing of cold and hot air and heat conduction from the heat conductive sheet. It can be uniformly reduced in a short period of time, and sweat can be removed from the air outlet by an air current, thereby eliminating the sense of discomfort. Furthermore, even in winter, heating can be performed almost uniformly, and air conditioning of the seats can be performed comfortably.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a Peltier module according to a first embodiment of the present invention; FIG. 2 is a perspective view of a Peltier module; FIG. With
The seat surface cover is configured to be cooled or heated by both convection by blowing of hot and cold air and heat conduction from the heat conductive sheet.

Thus, in summer, when the vehicle is operated, the supplied air flow is heat-exchanged to cool air by the Peltier module. At the same time, the Peltier module also exchanges heat with the heat conducting sheet and cools it. The cooled heat conductive sheet cools the seat surface cover by heat conduction.
Further, the cool air is conveyed to the seat surface cover and blows out from the seat surface cover. Therefore, the seat surface cover is cooled by both convection due to blowing of cold air and heat conduction from the heat conductive sheet.

In winter, when the vehicle is operated, the supplied air flow is exchanged with warm air by the Peltier module. At the same time, the Peltier module also exchanges heat with the heat conducting sheet and heats it. The heated heat conductive sheet heats the seat surface cover by heat conduction. Further, the warm air is conveyed to the seat surface cover and blows out from the seat surface cover. Therefore, the seat surface cover is heated by both convection due to the blowing of warm air and heat conduction from the heat conductive sheet.

In this manner, the seat surface cover is cooled or heated by both convection due to the blowing of cold and hot air and heat conduction from the heat conductive sheet. Therefore, in summer, heat is substantially uniformly transmitted from the heat conductive sheet. It can be reduced in a short time, and sweat can be removed from the air outlet by an air current, thereby eliminating the feeling of discomfort. Furthermore, even in winter, heating can be performed almost uniformly, and air conditioning of the seats can be performed comfortably.

According to a second aspect of the present invention, there is provided a Peltier module for cooling or heating, and a cooling / heating heat exchanger for cooling or heating air passing therethrough from a cooling or heating surface of the Peltier module. A waste heat heat exchanger that conducts heat from a waste heat surface of the Peltier module and exchanges heat with passing air, a blower that blows air to at least the cold / hot heat exchanger, and is connected to the cold / hot heat exchanger. hand,
An air passage body that forms an air passage that guides the air that has been heat-exchanged by the cold / hot heat exchanger to an air outlet provided in the seat; and a ventilation passage formed by combining the air passage body with the air passage body. In the summer season, the seating part of the seat and the backrest part are configured with a heat conductive sheet that cools or heats the surface on the side where the person sits and also exchanges heat with the air blown from the blower. Then, the surface of the Peltier module to be cooled or heated becomes a low temperature surface, and cools the cold / hot heat exchanger. The waste surface of the Peltier module becomes hot, and the waste heat exchanger becomes hot. Since the blower is driven to blow air to the cold / hot heat exchanger and waste heat heat exchanger,
The air blown to the cold / hot heat exchanger is cooled and flows into the ventilation path. At the same time, the surface of the Peltier module to be cooled or heated conducts heat to the heat conductive sheet and cools the heat conductive sheet. Since the ventilation passage is partially formed by the heat conduction sheet, the air passing through the ventilation passage also exchanges heat with the heat conduction sheet. Further, since the heat conductive sheet is provided in contact with the seat surface cover, the seat surface cover is cooled by heat conduction. An air outlet provided in the heat conductive sheet passes through an air outlet provided in the seat surface cover and blows out to the seat atmosphere to cool the human body.

Next, when the operation is performed in winter, the surface of the Peltier module to be cooled or heated becomes a high-temperature surface, and the cooling / heating heat exchanger is heated. The waste surface of the Peltier module is cold, and the waste heat exchanger is cold. Since the blower is driven to blow air to the cold / hot heat exchanger and the waste heat heat exchanger, the air blown to the cold / hot heat exchanger is heated,
It flows into the ventilation path. At the same time, the surface of the Peltier module to be cooled or heated also transfers heat to the heat conductive sheet and heats the heat conductive sheet. Since a part of the ventilation path is formed from the heat conduction sheet, the air passing through the ventilation path also exchanges heat with the heat conduction sheet. Further, since the heat conductive sheet is provided in contact with the seat surface cover, the seat surface is heated by heat conduction. An air outlet provided in the heat conductive sheet passes through an air outlet provided in the seat surface cover and blows out to the seat atmosphere to heat the human body.

In this manner, the seat surface cover is cooled or heated by both convection due to the blowing of cold and hot air and heat conduction from the heat conductive sheet. Therefore, in summer, heat is substantially uniformly transmitted from the heat conductive sheet. It can be reduced in a short time, and sweat can be removed from the air outlet by an air current, thereby eliminating the feeling of discomfort. Furthermore, even in winter, heating can be performed almost uniformly, and air conditioning of the seats can be performed comfortably.

According to a third aspect of the present invention, in the air conditioning system for a seat according to the second aspect, the heat conductive sheet is attached to a cooling or heating surface of the Peltier module, and the cold / hot heat exchanger is formed by the heat conductive sheet. By adopting a configuration in which heat is transferred, the heat conductive sheet is directly transferred from the cooling or heating surface of the Peltier module, thereby increasing the ability to cool or heat the seat surface cover and cooling or heating. Speed increases. Further, since the cooling or heating to the cold / hot heat exchanger can be performed by the heat conduction sheet, the blowing of the cold / hot air by the blower can also be performed.

According to a fourth aspect of the present invention, in the seat air conditioner of the first aspect, the heat conductive sheet is attached to a surface of the Peltier module for cooling or heating. Heat is transferred directly from the cooling or heating surface of the Peltier module, and the seat surface cover is cooled or heated by heat conduction.At the same time, the heat conductive sheet cools or heats the air that has flowed into the ventilation passage, and converts it to cool and hot air. Heat is exchanged and blown out from the air outlet.

As described above, since heat conduction and heat exchange for cold and hot air can be performed only by the heat conducting sheet, the apparatus can be downsized without the need for a heat exchanger for cooling and heating, and can be used in a limited space in the seat. Storage becomes easy. Furthermore, since the function of heat conduction is prioritized, the speed of cooling or heating is increased.

According to a fifth aspect of the present invention, in the seat air conditioner according to any of the second to fifth aspects, the air flowing into the ventilation passage is formed by the heat conduction sheet because the ventilation passage body is formed of a heat conduction sheet. It is cooled or heated by heat and exchanges heat with cold and hot air, is blown out from the air outlet, and is cooled or heated by two heat transfer functions of heat conduction and convection. Is prioritized, so that in summer, the function of removing sweat by airflow and eliminating the feeling of discomfort can be enhanced.

According to a sixth aspect of the present invention, in the air conditioner for a seat according to any of the second to fifth aspects, a heat conductive sheet is provided on a waste heat surface of the Peltier module or a waste heat heat exchanger. The seat is placed on the surface of the seat where the person sits and the backrest does not sit so that the heat is wasted by heat conduction.The waste heat of the Peltier module is transferred to the heat conducting sheet, and Heat is conducted to the non-seat surface.
In other words, since waste heat is processed on the surface where no person is seated, waste heat is blown out to a limited space in the seat, processing is performed more efficiently, and the performance of the Peltier module is improved. Also, the cooling or heating performance is improved.
