The door 25a may be disposed on the rear panel 23 or the right panel 24.

[0018] As shown in FIGS. 1 to 3, the dashboard 3 is obtained by cutting out a portion disposed on the front side of the interior of the vehicle, and has an internal air supply passage (not shown) and an air outlet 3a on the rear surface side. The cold air blowing pipe 6a of the spot cooler 6 is connected to the front side of one end of the air supply passage, and four air outlets 3a are connected to the rear side of the other end of the air supply passage. When the spot cooler 6 is operated by the control device 7, cold air is discharged from the four air outlets 3a into the internal space 27 through the internal air supply passage of the dashboard 3.

[0019] As shown in FIGS. 1 and 3, two heaters 4 are disposed in the internal space 27 on the lower panel 21 of the housing 2. The heater 4 may be of any type as long as it can heat the surrounding air without harmful exhaust, but a ceramic heater is preferably used from the viewpoint of being easy to carry and having excellent quick heating performance. The arrangement location of each heater 4 is not particularly limited, but it is preferably arranged as far apart as possible to uniformly heat the internal space 27. Each heater 4 is controlled to operate by the control device 7.

[0020] As shown in FIG. 1, a humidifier 5 for reproducing a high-temperature and high-humidity environment in summer is disposed in an internal space 27 on a lower panel 21 of a housing 2. The placement location of the humidifier 5 is not particularly limited, but it may be placed on the upper surface of the dashboard 3. The operation of the humidifier 5 is controlled by a control device 7.

[0021] As shown in FIG. 1, a control device 7 is disposed outside the housing 2. The control device 7 is electrically connected to a seat heater 14, a seat ventilation system (SVS) 15 of an automotive seat 10, a heater 4, a humidifier 5, and a spot cooler 6, and controls the operation of each of them.

[0022] The temperature control performance experience device 1 configured as described above operates as follows. Assemble the housing 2 at a desired location such as an exhibition hall, and arrange the automotive seat 10, the dashboard 3, the heater 4, the humidifier 5, the spot cooler 6, and the control device 7 inside the internal space 27 and outside. Then, electrically connect the seat heater 14 and the seat ventilation system (SVS) 15 of the automotive seat 10, the heater 4, the humidifier 5, the spot cooler 6, and the control device 7.

[0023] For example, when experiencing the performance of the seat ventilation system (SVS) 15 in a high-temperature and high-humidity environment in summer, first operate each heater 4 and the humidifier 5 by the control device 7 to make the internal space 27 in a high-temperature and high-humidity state. Also, in order to approximate the in-vehicle environment in summer more closely, a separate planar heater may be placed on the seating surface of the automotive seat 10 to additionally heat the seating surface.

[0024] After this state becomes a steady state, operate the spot cooler 6 by the control device 7 to blow cold air from the air outlet 3a of the dashboard 3 to reproduce the situation where the vehicle's air conditioner is operating, and operate the seat ventilation system (SVS) 15 by the control device 7. If you sit on the automotive seat 10 in this state, you can experience its cooling performance.

[0025] Also, when experiencing the performance of the seat heater 14 in a low-temperature environment in winter, first operate the spot cooler 6 with the control device 7 to make the internal space 27 in a low-temperature state. Also, to get closer to the in-vehicle environment in winter, the seat ventilation system (SVS) 15 of the vehicle seat 10 may be operated with the control device 7 to additionally cool the seating surface of the vehicle seat 10.

[0026] After this state becomes a steady state, operate the seat heater 14 with the control device 7. If you sit on the vehicle seat 10 in this state, you can experience its heating performance. Note that the spot cooler 6 connected to the dashboard 3 can be reconnected to the heater 4, and the heater 4 can be operated with the control device 7 to warm the internal space 27 and reproduce the situation where the vehicle's air conditioner is operating.

[0027] The present embodiment configured as described above has the following effects. Assemble the housing 2 at a desired location such as an exhibition hall, and arrange the vehicle seat 10, dashboard 3, heater 4, humidifier 5, spot cooler 6, and control device 7 inside the internal space 27 and outside. Then, the performance of the seat ventilation system (SVS) 15 can be experienced in a high-temperature and high-humidity environment created by operating the heater 4 and the humidifier 5. Also, the performance of the seat heater 14 can be experienced in a low-temperature environment created by operating the spot cooler 6. As a result, it becomes possible to experience the temperature control performance of the vehicle seat 10 equipped with the seat heater 14 and the seat ventilation system (SVS) 15 at a desired location such as an exhibition.

[0028] FIG. 4 shows a temperature control performance experience device 1A, which is another embodiment of the present invention. The differences from the temperature control performance experience device 1 are as follows: there are two vehicle seats for experience, namely the automotive seat 10 and the automotive seat 10A; there is one heater 4; and there is no humidifier 5. For the same components, the same reference numerals are used and the description is omitted. The automotive seat 10A is provided with a seat heater 14A instead of the seat heater 14, and a seat ventilation system (SVS) 15A instead of the seat ventilation system (SVS) 15 with respect to the automotive seat 10. The difference between the seat heater 14 and the seat heater 14A lies in the heating performance, and the seat heater 14A can perform rapid heating more than the seat heater 14. The difference between the seat ventilation system (SVS) 15 and the seat ventilation system (SVS) 15A lies in the cooling performance, and the seat ventilation system (SVS) 15A can perform rapid cooling more than the seat ventilation system (SVS) 15. The automotive seat 10 and the automotive seat 10A are arranged side by side in the left-right direction in the internal space 27 on the lower panel 21 of the housing 2. And the heater 4 is arranged in the internal space 27 on the lower panel 21 between the automotive seat 10 and the automotive seat 10A. Here, the seat heater 14A and the seat ventilation system (SVS) 15A respectively correspond to the "temperature control device" in the claims.

[0029] The temperature control performance experience device 1A configured as above operates as follows. Assemble the housing 2 at a desired location such as an exhibition hall, and arrange the automotive seat 10, the automotive seat 10A, the dashboard 3, the heater 4, the spot cooler 6, and the control device 7 inside the internal space 27 and outside.

[0030] For example, when experiencing the performance difference between the seat ventilation system (SVS) 15 and the seat ventilation system (SVS) 15A in a high-temperature environment in summer, first operate the heater 4 with the control device 7 to make the internal space 27 in a high-temperature state. Also, in order to get closer to the in-vehicle environment in summer, a separate planar heater may be placed on the seating surface of the vehicle seat 10 to additionally heat the seating surface.

[0031] After this state becomes a steady state, operate the spot cooler 6 with the control device 7 to send out cold air from the air outlet 3a of the dashboard 3 to reproduce the situation where the vehicle air conditioner is operating, and operate the seat ventilation system (SVS) 15 and the seat ventilation system (SVS) 15A with the control device 7. If you alternately sit on the vehicle seat 10 and the vehicle seat 10A in this state, you can experience the difference in their cooling performance.

[0032] Also, when experiencing the performance difference between the seat heater 14 and the seat heater 14A in a low-temperature environment in winter, first operate the spot cooler 6 with the control device 7 to make the internal space 27 in a low-temperature state. Also, in order to get closer to the in-vehicle environment in winter, operate the seat ventilation system (SVS) 15 and the seat ventilation system (SVS) 15A with the control device 7 to additionally cool the seating surfaces of the vehicle seat 10 and the vehicle seat 10A.

[0033] After this state becomes a steady state, operate the seat heater 14 and the seat heater 14A with the control device 7. If you alternately sit on the vehicle seat 10 and the vehicle seat 10A in this state, you can experience the difference in their heating performance. Note that the spot cooler 6 connected to the dashboard 3 may be reconnected to the heater 4, and the heater 4 may be operated with the control device 7 to warm the internal space 27 to reproduce the situation where the vehicle air conditioner is operating.

[0034] The present embodiment configured as described above has the following effects. At a desired location such as an exhibition hall, the housing 2 is assembled, and the automotive seat 10, automotive seat 10A, dashboard 3, heater 4, spot cooler 6, and control device 7 are arranged inside the internal space 27 and outside. Then, it is possible to experience the difference in performance between the seat ventilation system (SVS) 15 and the seat ventilation system (SVS) 15A in a high-temperature environment created by operating the heater 4. Also, it is possible to experience the difference in performance between the seat heater 14 and the seat heater 14A in a low-temperature environment created by operating the spot cooler 6. As a result, at a desired location such as an exhibition, it becomes possible to comparatively experience the temperature control performance between the automotive seat 10 equipped with the seat heater 14 and the seat ventilation system (SVS) 15, and the automotive seat 10A equipped with the seat heater 14A and the seat ventilation system (SVS) 15A.
