BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temperature control device capable of cooling or heating.

[0002]

2. Description of the Related Art Heretofore, as a seat temperature adjusting device of this type, there has been one as described in Japanese Patent Laid-Open No. 5-277020. FIG. 9 shows a conventional seat temperature control device described in the above publication.

In FIG. 9, a temperature control device for a seat is a seat 3 for an automobile composed of a backrest part 1 and a seating part 2, a Peltier module 4 arranged in a space below the seat 3, and a Peltier module 4 thereof. Connected to the main heat exchanger 5 for cooling or heating the air flow, a waste heat heat exchanger 6 for exchanging waste heat into the air flow, and a surface cover 7 on which the occupants of the backrest portion 1 and the seating portion 2 sit. Provided in the air flow outlet 8 for blowing out the air flow
An air flow passage 9 provided in the backrest part 1 and the seating part 2 for communicating the air flow blown from the main heat exchanger 5 to the air flow outlet 8, and the waste heat heat exchanger. 6, a waste heat air flow passage 10 that conveys the waste heat air flow from the Peltier module 4,
The main heat exchanger 5 and the waste heat heat exchanger 6 connected to each other were composed of a blower 11 for conveying an air flow.

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 temperature of the seat has been adjusted by cooling or heating the occupant's back and buttocks.

Further, as another conventional heat transfer device for a seat, there is a heat transfer device as described in Japanese Patent Publication No. 10-504977. FIG. 10 shows another conventional seat temperature adjusting device described in the above publication.

In FIG. 10, a temperature control device for a seat is formed in the seat 3 and inside the seat 3, and contacts a surface cover 7 of the seat to effectively cool or heat the seated occupant by heat conduction. Air channel 12 and air channel 1 which circulate the temperature-controlled air
2, a heat pump 13 having a Peltier module 4 for cooling or heating air, a control switch 14 for operating the device and at the same time selecting a heating or cooling mode of operation, and a selected heating Alternatively, a controller 15 that automatically adjusts the operation of the heat pump 13 to send the temperature-controlled air according to the cooling operation, and a main heat exchanger 5 that is connected to the heat pump 13 and selectively heats or cools the air. , A main heat exchanger blower 16 for sending heated or cooled air, a waste heat heat exchanger 6 for removing unnecessary waste heat from the Peltier module 4, and a waste heat for sending air to the waste heat heat exchanger 6. It was composed of a heat exchanger blower 17.

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 temperature of the seat is adjusted by cooling or heating the back and buttocks of the occupant seated from the front cover 7 of the seat 3 by heat transfer by heat conduction.

[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.

Further, since there is only one function of a cooling / warming air flow blowing method and a method of circulating air through the air channel 12 to heat and cool the seat by heat conduction, the heat conduction alone eliminates the feeling of discomfort in the summer. do not do. Further, each of the blowing methods of the cold / warm air flow has a problem that the temperature rises before the air flow is heat-exchanged with the cold air and conveyed.

Even when both convection and heat conduction functions are provided, it is not possible to change the ratio of the amount of heat given to convection and heat conduction. Therefore, in summer use, the user sweats and heat conduction occurs. When the cool air due to convection is desired rather than the cool feeling due to, the heat quantity ratio of the cool air due to convection cannot be increased, and there is a problem that the user must use it with discomfort. Furthermore, in winter use, even if the user desires conduction heat due to heat conduction rather than warm air due to convection, the heat quantity ratio of heat conduction could not be changed. Had the problem of having to use while holding.

The present invention solves the above-mentioned conventional problems. The temperature of a region of the seat surface in contact with a human body is reduced substantially uniformly in a short time by both the air blowing by the convection section and the heat conduction by the heat conduction section. At the same time, it also eliminates the feeling of sweatiness. Since the amount of heat supplied from the convection section and the heat conduction section can be changed, the comfortable seating that has both cooling and heating can be achieved by changing the ratio of convection and heat conduction according to the preference of the user. A temperature control device having a feeling can be provided.

[0013]

In order to solve the above-mentioned conventional problems, the temperature control apparatus of the present invention diffuses heat from at least one heat source for cooling or heating and heat conduction from the heat source. The temperature is controlled by a heat conduction section, a blower that blows air, and a convection section that blows out the air blown by this blower into cold or warm air with the heat from the heat source, or blows out as mere wind, and the heat conduction section and the convection section. The temperature controlled part is provided, and the ratio of the amount of heat given to the heat conducting part and the amount of heat given to the convection part is variable.

Thus, in the summer, the air cooled by the heat source is exchanged with the cool air by the blower. At the same time, the heat source also transfers heat to the heat conducting section for cooling. The cooled heat conducting portion cools the temperature controlled portion by heat conduction.
Further, the cold air is conveyed to the temperature controlled part and blows out from the temperature controlled part. Therefore, the temperature controlled part is cooled substantially uniformly in a short time by both convection due to the blowing of cold air and heat conduction from the heat conduction part. Furthermore, since the ratio of the amount of heat supplied to the convection section and the heat transfer section can be changed, the ratio of the amount of heat transferred from the heat transfer section when sweat is to be rapidly removed in summer. It is possible to quickly eliminate the feeling of discomfort by suppressing the temperature to be low and conversely increasing the ratio of the amount of heat supplied from the convection section.

Next, in the winter, when operating, the air heated by the heat source is heat-exchanged with warm air. at the same time,
The heat source also transfers heat to the heat conducting section to heat it. The heated heat conducting portion heats the temperature controlled portion by heat conduction. Further, the warm air is conveyed to the temperature controlled part and blows out from the temperature controlled part. Therefore, the temperature controlled part is heated almost uniformly in a short time by both convection due to the blowing of warm air and heat conduction from the heat conduction part. Furthermore, since the ratio of the amount of heat supplied to the convection section and the heat conduction section can be changed,
When the user feels the wind from the convection section uncomfortable and wants the conduction heat from the heat conduction section, the ratio of the amount of heat of the warm air supplied from the convection section is kept low to reduce the heat conduction from the heat conduction. A comfortable warm feeling for the user can be realized by increasing the ratio of.

Since the ratio between convection and heat conduction can be freely changed in this manner, it is possible to provide a temperature adjusting device having a comfortable seating feeling for the user.

(Embodiment 5) FIG. 7 is a block diagram of a temperature adjusting apparatus according to Embodiment 5 of the present invention. The same reference numerals as those in the first embodiment have the same structure, and the description thereof will be omitted.

The difference from the first embodiment is that one heat source 20
As shown in FIG. 7, the heat source 20 and the blower 22 are individually provided in the seat portion 51 and the back portion 52 of the seat 50, respectively. In FIG. 7, reference numeral 40 is a Peltier module for cooling or heating, and 41 is a cooling / heating heat exchanger for transferring heat from the surface for cooling or heating of the Peltier module 40 to cool or warm the passing air. Reference numeral 42 denotes a waste heat heat exchanger, which transfers heat from the waste heat surface of the Peltier module 40 and exchanges heat with the passing air. 22 is a blower,
Air is blown to the cold heat heat exchanger 41 and the waste heat heat exchanger 42. Reference numeral 43 denotes an air passage body 4, which is connected to the cold / heat exchanger 41 and guides the air heat-exchanged by the cold / heat exchanger 41 to the blowout hole 25 provided in the seat surface cover 44.
5 is formed. Reference numeral 46 denotes a heat conductive sheet, which forms an air passage 45 in combination with the air passage body 43 and cools the seat surface cover 44 of the seating portion 51 of the seat 50 and the backrest portion 52 when heat is transferred from the cool / heat exchanger 41. Alternatively, heating is performed, and heat is also exchanged with the air blown by the blower 22 in the formed ventilation passage 45, and a blowout hole 25 for blowing the cooled or heated air is also provided and blown out.

The operation and action of the seat temperature control device configured as described above will be described below.

When the Peltier module 40 is operated in summer, the surface of the Peltier module 40 for cooling or heating becomes a low temperature surface, and the cold heat exchanger 41 is cooled. The surface of the Peltier module 40 on which waste heat is generated becomes a high temperature surface, and the temperature of the waste heat heat exchanger 42 becomes high.
Since the blower 22 is driven to blow air to the cold / heat heat exchanger 41 and the waste heat heat exchanger 42, the cold / hot heat exchanger 41 cools the blown air. At the same time, the cold heat exchanger 41 also transfers heat to the heat conductive sheet 46 to cool the heat conductive sheet 46 as well. The cooled air flows into the ventilation passage 45. Since the ventilation passage 45 is partially formed by the heat conduction sheet 46, the air passing through the ventilation passage 45 also exchanges heat with the heat conduction sheet 46. Further, since the heat conductive sheet 46 is provided in contact with the seat surface cover 44, the seat surface cover 44 is cooled by heat conduction. Blow-out hole 2 provided in seat surface cover 44 from blow-out hole 25 provided in heat-conducting sheet 46
Pass 5 and blow into the seat atmosphere.

Next, when the Peltier module 40 is operated in the winter, the surface of the Peltier module 40 to be cooled or heated becomes a high temperature surface, and the cold heat exchanger 41 is heated. The surface of the Peltier module 40 on which waste heat is generated becomes a low temperature surface, and the temperature of the waste heat heat exchanger 42 becomes low. Since the blower 22 is driven to blow air to the cold heat exchanger 41 and the waste heat heat exchanger 42, the cool heat exchanger 41 warms the blown air. At the same time, the cold / heat exchanger 41 transfers heat to the heat conductive sheet 46 and transfers heat to the heat conductive sheet 4.
6 is also heated. The heated air flows into the ventilation passage 45. Since the ventilation passage 45 is partially formed of the heat conduction sheet 46, the air passing through the ventilation passage 45 also exchanges heat with the heat conduction sheet 46. Further, since the heat conduction sheet 46 is provided in contact with the seat surface cover 44, the seat surface cover 44 is heated by heat conduction. From the blowout holes 25 provided in the heat conductive sheet 46, they pass through the blowout holes 25 provided in the seat surface cover 44 and blow out into the seat atmosphere. Further, the convection and heat conduction can change the supply of the heat quantity as already described in the first to third embodiments, so that the heat quantity ratio of the convection and the heat conduction can be set to a desired distribution.

As described above, in this embodiment, since the Peltier module 40 which is the heat source 20 and the blower 22 are individually provided in each of the seat portion 51 and the back portion 52, the heat quantity of the seat portion 51 and the back portion 52 is increased. Can be easily changed individually. The cool / heat exchanger 41 cools or heats the blown air, and at the same time, transfers heat to the heat conductive sheet 46 to cool or heat the seat surface cover 4.
No. 4 can be cooled or heated by both convection due to the blowing of cold and warm air and heat conduction from the heat conduction sheet 46, and the ratio of the amount of heat supply between convection and heat conduction can be changed. In particular, in the summer, the heat conduction from the heat conduction sheet 46 reduces the heat distribution substantially uniformly, and by increasing the heat quantity ratio by convection,
The sweat can be rapidly removed from the blowout hole 25 by the air flow, and the feeling of discomfort can be eliminated. Further, in the winter season, by increasing the heat supply for heat conduction rather than convection, the heat can be rapidly and almost uniformly conducted, and the temperature of the seat 50 can be comfortably adjusted.

It is to be noted that the temperature adjusting device of the present invention is considered to be a seat 50 on which a user can sit, and a seat part 51 on which the occupant of the seat sits and a back part 52 in contact with the back of the occupant. As shown in FIG. 8, a head contact portion 53 contacting the occupant's head and / or an armrest portion 54 contacting the occupant's elbow is used as a seat, and the head contact portion 53, the armrest portion. The heat conduction from the heat conduction unit 21 and the air flow from the convection unit 23 may be performed on the air conditioner 54. And
In the winter, when the legs are warmed and the head is cooled, as in the case of head cold foot heat, the user can enjoy the warmth and prevent drowsiness while driving. In addition, regarding the armrests, it is possible to prevent the indoor equipment that the user comes into contact with from getting hot when the automobile is parked in summer. In this way, even if a plurality of temperature controlled parts are provided, they can be realized by individually providing temperature control devices.

Further, the driving state is controlled according to the environmental conditions inside or outside the vehicle or the running conditions.

As described above, in the present embodiment, by detecting the temperature of the temperature control part 24, the heat source 20, the heat conducting part 21, the convection part 23 or the atmosphere, the convection part 23 and the heat conducting part 21 are detected. The ratio of the amount of heat given can be changed. Then, it is possible to realize a temperature adjusting device which is comfortable for the user and which uses the heat quantity ratio of the convection section and the heat conduction section.

The heat source 20 of the temperature control device of the present invention can be used as long as it has both cooling and heating functions. A Peltier module or heat pump can be used as a heat source with high reliability. If the Peltier module is used, it is small and lightweight, and when it is used as a temperature control device for automobiles, the DC power supply can be used as it is, and the configuration can be simplified without the need for a converter or the like. Furthermore, fine temperature control is possible. In addition, the heat pump has a large output power with respect to the input power,
High efficiency.

As described above, the temperature control device of the present invention is applied to all seats such as automobile seats, motorcycle seats, bicycle seats, train seats, airplane seats, massage seats, sofas, and futons. It can be used for blankets, heads, head pads, pillows, carpets, handles, gloves, shoes, socks, clothes, hats, eye masks, electric jar pots, coolers.

[0080]

As described above, according to the temperature control device of the present invention, the temperature control device has both functions of convection by blowing cold and warm air and heat conduction from the heat conducting portion, and supplies the convection portion and the heat conducting portion. Since the ratio of the amount of heat generated can be changed, the sense of discomfort can be eliminated by increasing the ratio of the amount of heat supplied from the convection section when sweat is desired to be removed. Further, in the winter, when the user feels the wind from the convection section uncomfortable and desires the conduction heat from the heat conduction section, the ratio of heat conduction to heat conduction can be increased. In this way, by freely changing the ratio of convection and heat conduction, it is possible to provide a temperature adjusting device having a comfortable seating feeling according to the taste of the user.
