2. Description of the Related Art In recent years, creation and evaluation of a comfortable thermal environment from a human standpoint has been required. Conventionally, when housing-related members such as flooring materials of various materials and living-related products such as textiles such as carpets are used as finishing materials for thermal environment control in offices and ordinary houses, performance evaluation of the physical The emphasis was on quality. At present, many new materials have appeared in places of living environment, but it is hard to say that all of them are materials suitable for human sensitivity. On the other hand, from the viewpoint of improving the quality of life, there is a demand for performance evaluation in terms of ease of use and sensory compatibility. To do so, it is necessary to create a universal suitability index obtained from the correlation between the physical properties of the material and the amount of human perception.

[0003] A thermal sensation measurement experiment has been performed to create such a universal suitability index, but a conventional measurement experiment was performed as follows. An air thermostat is prepared to keep the temperature of the heat presenting plate, which is a material, constant, and the heat presenting plate is stored therein. And at the time of measurement experiment, quickly take out the heat presentation board from the air thermostat,
The subject was instantly touched, and the subjective amount of the feeling of warmth and comfort and the feeling of comfort were reported on a prepared scale (for example, 7 steps from very warm to very cold, 4 steps from comfortable to uncomfortable). In addition, the sensed temperature was reported as it was felt.

[0004] However, in the conventional measuring method as described above, if the temperature change is taken into the measuring conditions, a large number of air thermostats is required, the cost is increased, and a wide experimental space must be secured. In addition, when the temperature presentation plate is taken out of the air oven, the surface temperature of the plate starts to decrease from that moment, and the cooling rate depends on the thermal conductivity and heat capacity of the material. Influences the amount of feeling. Therefore, the reliability of the obtained data could not be said to be sufficient. For this reason, the experimental reports so far have been limited to measurements in the room temperature range of the laboratory.

Alternatively, a sheet-like heat generating layer formed by printing is particularly preferable because a wide range of resistance can be obtained and a high voltage to a low voltage can be handled. Specifically, as described in JP-A-3-145090, flat clay minerals such as sericite, mica mineral maskovite, and phlogopite having an average diameter of 5 to 100 μm and a thickness of 0.1 to 20 μm.

As described above, the output of the optical sensor 10 is connected to a control unit (not shown). When the optical sensor 10 detects, for example, the interruption of infrared light, a timer provided in the control unit starts, and a preset value is set.

Next, the operation will be described. The device of the present invention is a method in which a human palm, a finger or the sole of a foot or the like is brought into contact with a surface of various materials set at various temperatures in advance for a certain period of time to provide a thermal sensation, a comfortable sensation, and a subjective amount of sensed temperature. This device is useful for determining the correlation between physical quantities such as thermal conductivity, specific heat, specific gravity, and surface roughness of a material and the above-mentioned human senses. First, the operator attaches the temperature presenting plate 1 made of a required material to the storage box 11 and operates the temperature control device to set the presented temperature. Then, electric power is supplied to the heating resistor layer 4 of the planar heating section 2 to perform heating, and the heat is transmitted to the metal sheet 3 via the insulating layer 5, where the heat is uniformly distributed, and the heat is distributed. The temperature is transmitted to the temperature indicating plate 1. Further, temperature control is performed by a temperature monitor using a thermocouple 7 or 8. For this reason, the surface temperature of the temperature presentation plate 1 is controlled very uniformly to the set temperature. Here, a method of laying a string-shaped heating element such as a nichrome wire instead of the sheet-shaped heating resistor is also conceivable. This makes it impossible to provide a uniform thermal stimulus to the warm and cold sensation receptors scattered on the palm or the like.

When the measurement site of the subject comes into contact with the surface 1a of the temperature presenting plate 1 whose temperature is uniformly controlled in this manner, for example, the optical sensor 10 including infrared transmission sensors provided on the right and left sides of the temperature detection plate 1 detects the interruption of infrared light. Then, the detection signal is sent to the control means (computer). The timer provided in the control means measures the time from the time when the detection signal is received, and notifies the subject of the elapse of time by a notification means such as a buzzer when a preset time has elapsed. In this type of conventional measurement, the operator tells the subject time to time,
Although the work was performed while instructing, according to the apparatus of the present invention, it is possible for the subject alone to perform the measurement in accordance with the instructions on the personal computer screen, except for the explanation before starting the experiment.

Although the present invention has been described based on one configuration example, the present invention is not limited to the above configuration example, and various modifications and changes are possible. For example, assuming floor heating in particular,
In order to obtain a feeling of comfort or thermal sensation due to the material, not only the contact portion of the sole of the foot but also the heating of the leg portion by far-infrared radiation heat from the surface material has an effect. Therefore, an apparatus having a size that can be contacted by applying weight with both feet can be easily obtained by using a planar heating element obtained by screen printing on the heating element section, and sensory measurement for this purpose can be performed.

Example 2 FIG. 3 shows that 10 subjects, men and women in their 20s to 50s, touched four types of temperature-controlled temperature presentation boards for 3 seconds as subjects, and provided four levels of comfort scales ( It shows the relationship between the average value and the surface temperature when the subjective amount is reported in comfortable: 4, slightly comfortable: 3, slightly uncomfortable: 2, uncomfortable: 1). The peak temperature indicating the degree of comfort is a temperature slightly lower than the average temperature of 31.5 ° C. in the portion above the first joint of the middle finger of the subject. At a temperature higher than this, a result was obtained in which the degree of discomfort increased with a material having a high thermal conductivity at the same surface temperature as compared with a material with a low thermal conductivity.

Example 3 FIG. 3 shows that 10 subjects, men and women in their 20s to 50s, touched four kinds of temperature-controlled temperature display boards for 3 seconds. This shows the relationship with the true temperature. Regarding this relationship, there was no difference between the materials, and a linear relationship having almost the same gradient was shown. A temperature lower than the average temperature of 31.5 ° C. in the portion above the first joint of the middle finger of the subject tended to feel higher and a higher temperature lower.
