  The present invention relates to a simulated skin device and a characteristic evaluation method using the same.

2. Description of the Related Art Conventionally, a test apparatus that simulates human skin has been used to evaluate physical properties such as heat retention characteristics and transpiration characteristics of fabrics used for clothes (see, for example, Non-Patent Document 1). In the test apparatus described in Non-Patent Document 1, an electric heater for heating the metal plate is provided on the lower surface side in order to adjust the surface temperature of the metal plate to which the test sample is attached to the target temperature. In addition, all the heat output from the electric heater according to the supplied power is radiated from the upper surface of the metal plate, that is, the heat radiation from the lower and side surfaces of the metal plate and the direct heat radiation from the electric heater are suppressed. For this purpose, the side and bottom surfaces of the metal plate and the periphery of the electric heater are surrounded by a guard, and the guard heater embedded in the guard is controlled so that the temperature of the guard matches the temperature of the electric heater.
“IS 11092: 1993 (E) (ISO 11092: 1993 (E))”, International Organization for Standardization (International Organization for Standardization)

  In the test apparatus disclosed in Non-Patent Document 1, the amount of heat released from the upper surface of the metal plate is obtained from the power supplied to the electric heater. It is necessary to match the temperature of the heater and the temperature of the guard to suppress heat dissipation from other than the upper surface of the metal plate.

  However, in such a configuration, when the temperature of the metal plate surface, that is, the temperature of the electric heater is changed, it is difficult to follow the temperature of the guard without delay in accordance with the temperature change of the electric heater. For this reason, the test apparatus can perform characteristic evaluation in a steady state in which the surface temperature of the metal plate is kept constant, but performs characteristic evaluation in a transient state in which the surface temperature of the metal plate changes with time. It was difficult.

  On the other hand, for example, when a test is performed assuming that the air enters from a hot outdoor to a cool indoor, or from a cold outdoor to a warm indoor heated, a transient in which the skin temperature changes over time An apparatus capable of simulating a state has been desired.

  The present invention has been made to solve the above problems, and can simulate a transient state in which the surface temperature of the simulated skin can be adjusted in real time and the skin temperature changes over time. It aims at providing the characteristic evaluation method using it.

A simulated skin device according to the present invention is provided between a simulated skin member, a thermoelectric conversion element capable of switching between heating and cooling, which converts electrical energy and thermal energy, and the simulated skin member and the thermoelectric conversion element. A heat flux detecting means for transmitting thermal energy between the simulated skin member and the thermoelectric conversion element and detecting an amount of transmitted thermal energy transmitted between the simulated skin member and the thermoelectric conversion element ; A heat insulating member that cuts off heat energy transmitted between the simulated skin member and the thermoelectric conversion element without going through the heat flux detecting means, and electric power supplied to the thermoelectric conversion element based on the detection result of the heat flux detecting means And a control means for adjusting.

  According to the simulated skin device of the present invention, the heat energy transmitted between the simulated skin member and the thermoelectric conversion element without the heat flux detection means is blocked by the heat insulating member. As a result, almost all of the heat energy is transmitted through the heat flux detection means, so that the amount of heat energy transferred between the simulated skin member and the thermoelectric conversion element can be detected in real time and with high accuracy. Can do. Since the temperature of the simulated skin member can be adjusted in real time by adjusting the power supplied to the thermoelectric conversion element based on the result detected in real time, the transient state in which the skin temperature changes over time is simulated. It becomes possible to do.

  The simulated skin apparatus according to the present invention includes temperature detection means for detecting the surface temperature of the simulated skin member, and the control means controls the power supplied to the thermoelectric conversion element further considering the detection result of the temperature detection means. It is preferable to do.

  If it does in this way, it will become possible to adjust the calorific value of a thermoelectric conversion element also in consideration of temperature nonuniformity on the surface of a simulation skin member.

  In the simulated skin device according to the present invention, a Peltier element is preferably used as the thermoelectric conversion element. Thus, when a Peltier element is used as a thermoelectric conversion element, the simulated skin member can be cooled as well as heated by switching the voltage application direction, and the amount of heating can be adjusted by adjusting the amount of power supplied. In addition, the cooling amount can be adjusted appropriately.

  The characteristic evaluation method according to the present invention is characterized by evaluating the characteristic of the fabric using the simulated skin device.

  As described above, the simulated skin device according to the present invention can adjust the surface temperature of the simulated skin member in real time, and can simulate a transient state in which the skin temperature changes with time. Therefore, according to the characteristic evaluation method according to the present invention, it is possible to evaluate not only the steady state where the skin surface temperature is kept constant, but also the physical characteristics of the fabric in a transient state where the skin temperature changes over time. It becomes possible.

  According to the present invention, the heat energy transmitted between the simulated skin member and the thermoelectric conversion element without passing through the heat flux detecting means is cut off, and the power supplied to the thermoelectric conversion element based on the detection result of the heat flux detecting means. Since the surface temperature of the simulated skin member can be adjusted in real time, it is possible to simulate a transient state in which the skin temperature changes with time.

A humidity sensor 74 is provided.

  First, the simulated skin apparatus 1 which is a main configuration of the characteristic evaluation apparatus will be described. The simulated skin apparatus 1 adjusts the surface temperature of the simulated skin member 10 to a target temperature by heating or cooling the simulated skin member 10 with a Peltier element 20 disposed below the simulated skin member 10, and drives the pump 54. By supplying the water stored in the tank 56 to the surface of the simulated skin member 10, the skin of a person or the like is simulated.

  The simulated skin member 10 includes a square copper plate 12, a square aluminum plate 14 laminated on the upper surface of the copper plate 12, and a simulated skin layer 16 laminated on the upper surface of the aluminum plate 14. As the copper plate 12, a copper plate having a length of 200 mm and a width of 200 mm was used. As the aluminum plate 14, one having a size of 200 mm in length and 200 mm in width was used. For the simulated skin layer 16, for example, a fabric knitted with nylon fibers is preferably used in order to diffuse water on the surface. In addition, it is preferable to apply a paste having a high thermal conductivity between the copper plate 12 and the aluminum plate 14.

  Four temperature sensors 18 are attached to the surface of the aluminum plate 14 at equal intervals (see FIG. 2). The temperature sensor 18 detects the surface temperature of the aluminum plate 14, that is, the temperature of the simulated skin surface, and functions as a temperature detecting means described in the claims.

As the heat flux sensor 20, a known heat flux sensor composed of a pair of thermocouples sandwiching a thin film of a substance that becomes a thermopile or a thermal resistor can be used. In the present embodiment, a commercially available heat flux sensor is used. Each heat flux sensor 20 is also connected to an electronic control device 40 described later, and a detection signal corresponding to the heat flux value is output to the electronic control device 40.

  A Peltier element 22, which is a thermoelectric conversion element that converts electric energy and heat energy, is attached to the lower surface of each heat flux sensor 20 (see FIG. 2). Thermal energy released from the upper surface of the Peltier element 22 is transmitted to the copper plate 12 and the aluminum plate 14 via the heat flux sensor 20, and released from the upper surface of the aluminum plate 14 via the simulated skin layer 16. In addition, it is preferable to apply | coat a paste with high heat conductivity between the copper plate 12 and the heat flux sensor 20, and between the heat flux sensor 20 and the Peltier element 22. FIG.

  Each Peltier element 22 is connected to a Peltier element driving power source (hereinafter simply referred to as “power source”) 42 for supplying power. The amount of heat generated or the amount of heat absorbed by each Peltier element 22 is individually adjusted by controlling the output of the power source 42. Further, switching between heating and cooling by the Peltier element 22 is performed by reversing the polarity of the applied voltage. The power source 42 is connected to an electronic control device 40 described later, and its operation is controlled by a control signal from the electronic control device 40.

  A fan 24 is attached to the lower surface of each Peltier element 22 for releasing heat released from the lower surface of each Peltier element 22 to the outside.

  The side surface and bottom surface of the simulated skin member 10, the side surface of each heat flux sensor 20, and the side surface of each Peltier element are surrounded by a heat insulating member 30 that blocks heat. For example, cork is used as the heat insulating member 30.

  In the present embodiment, the Peltier element 22 is attached via the heat flux sensor 20, and the side surface and bottom surface of the simulated skin member 10, the heat flux sensor 20, and the side surfaces of each Peltier element 22 are surrounded by the heat insulating member 30. All the heat energy emitted from the upper surface of the Peltier element 22 is transmitted to the copper plate 12 and the aluminum plate 14 via the heat flux sensor 20 and is emitted from the upper surface of the aluminum plate 14.

  In addition, 16 sweat holes 50 are formed at equal intervals in the copper plate 12, the aluminum plate 14, and the heat insulating member 30 constituting the simulated skin member 10 so as to penetrate these (see FIG. 2). Each sweat hole 50 is connected to a tank 56 that stores water and a pipe 52 that connects each sweat hole 50. The pipe 52 is provided with a pump 54. When the pump 54 is driven, water stored in the tank 56 is supplied to the upper surface of the aluminum plate 14 constituting the simulated skin member 10 through the pipe 52 and the sweat holes 50. Is done. The water supplied on the aluminum plate 14 is uniformly diffused by the simulated skin layer 16. A mantle heater 58 is attached around the tank 56, and the water stored in the tank 56 is adjusted to an appropriate temperature (eg, 36 ° C.).

  The above-described solenoid valve (not shown) for opening and closing the pump 54 and each pipe 52 is connected to the electronic control device 40 via a communication line such as RS232C, for example, and is controlled by a control signal from the electronic control device 40. Be controlled. That is, the amount of water supplied to the simulated skin member 10 is adjusted by controlling the pump 54 and the electromagnetic valve by the electronic control unit 40. In addition, it is good also as a structure which adjusts the quantity of the water supplied to the simulated skin member 10 by using the thing of the type which squeezes a tube with a roller and pumps water as a pump, and controls the rotation speed of this roller. .

  The electronic control unit 40 includes a microprocessor that performs calculations, a ROM that stores programs for causing the microprocessor to execute each process, a RAM that stores various data such as calculation results, and the like. As the electronic control device 40, a personal computer is preferably used. A dedicated controller may be used in place of the personal computer.

  As described above, the temperature sensor 18, the heat flux sensor 20, the power source 42, the pump 54, and the like are connected to the electronic control unit 40. The electronic control unit 40 controls the power supply 42 based on the detection results from the temperature sensor 18 and / or the heat flux sensor 20 so that the temperature of the aluminum plate 14 matches the preset target temperature stored. The electric power supplied to the Peltier element 22 is adjusted. In other words, the electronic control device 40 functions as a control unit described in the claims.

  The electronic control device 40 is connected to an input device 44 such as a keyboard for setting a sequence to be described later. The electronic control device 40 is also connected to a display 46 that displays measurement results such as sequence setting status and temperature. Then, the electronic control unit 40 adjusts the surface temperature of the simulated skin member 10 according to a preset and stored sequence, and drives the pump 54 and the like to supply water to the surface. In this way, the simulated skin device 1 simulates the skin condition by adjusting the surface temperature of the simulated skin member 10 and the amount of sweat (water supply amount).

  A frame body 82 to which a fabric 80 as a sample is fixed is detachably loaded on the simulated skin apparatus 1. The frame body 82 is a square frame body constituted by two sets of two sides facing each other. A material such as cork, for example, is used for the frame 82, similarly to the heat insulating member 30. The fabric 80 is cut into a square shape that is slightly smaller than the frame body 82, and its outer edge is fixed to the frame body 82 over the entire circumference.

  A windshield 90 is detachably mounted on the upper portion of the frame 82 to block the wind from the outside and suppress the diffusion of heat and moisture to the outside to keep the measurement environment in an appropriate state. The windshield 90 is preferably formed of, for example, an acrylic resin or a vinyl chloride resin in order to facilitate observation of the inside. A blower fan 92 that sends wind to the fabric 80 and suppresses heat retention is detachably attached to the upper portion of the windshield 90. The blower fan 92 is controlled such that the wind speed is 0 to 5 m / sec, for example.

  In addition, the characteristic evaluation apparatus 100 includes a plurality of temperature sensors, humidity sensors, and the like that simultaneously and temporally measure the space between the fabric 80 and the simulated skin member 10 and the temperature and humidity in the windshield 90. . For example, a temperature sensor 71 that measures the temperature of the space and a humidity sensor 73 that measures the humidity of the space are provided between the fabric 80 and the simulated skin member 10. A temperature sensor 72 that measures the temperature of the space, a humidity sensor 74 that measures the humidity of the space, and a wind speed sensor 75 that detects the wind speed in the windshield 90 are provided inside the windshield 90, that is, outside the fabric 80. It has been. In the present embodiment, T-type thermocouples are used as the temperature sensors 71 and 72. Further, as the wind speed sensor 75, a fine wind speed sensor for indoor wind speed was used. The temperature sensors 71 and 72, the humidity sensors 73 and 74, and the wind speed sensor 75 are connected to the electronic control device 40, and measurement results from the sensors are input to the electronic control device 40.

  Next, taking as an example the case of evaluating physical properties such as heat retention characteristics and transpiration characteristics of the fabric using the characteristic evaluation apparatus 100, the operation of the simulated skin apparatus 1 and the characteristics evaluation method of the fabric using the simulated skin apparatus 1 Will be described.

  In the characteristic evaluation apparatus 100, first, a sequence for defining the operation content and the operation sequence from the start of measurement is set and stored in the memory of the electronic control unit 40. The characteristic evaluation apparatus 100 automatically adjusts the temperature of the simulated skin surface, the amount of sweat, and the like according to this sequence, and simultaneously and temporally changes the environment inside and outside the clothes between the simulated skin and the clothes at that time. taking measurement.

  An example of a sequence setting screen displayed on the display 46 is shown in FIG. This setting screen includes a sequence number input column 110 for inputting the total number of set sequences, a display sequence selection column 112 for selecting a sequence number to be displayed, and a setting content column for displaying the setting content of the selected sequence. 114 etc. are displayed. In the display example shown in FIG. 3, the setting contents of the selected first sequence among the five sequences set in the sequence number input field 110 are displayed. In the present embodiment, the maximum number of sequences that can be entered in the sequence number input field 110 is 15.

  The sequence setting content column 114 includes an elapsed time input column 116 for inputting the control start timing of the sequence according to the elapsed time from the start of control, and a heat for selecting whether the control is based on the temperature value or the heat flux value. A control method input field 118, a pump control method input field 120 for inputting a control method such as ON / OFF of the pump 54 and a water supply amount, and a thermal control operation input field for inputting a target surface temperature of the simulated skin member 10. 122 etc. are provided.

  If the “OK button” 124 is selected when the setting input is completed, the input setting is confirmed. On the other hand, when the “Cancel” button 126 is selected, the setting is not finalized and the screen returns to the previous screen. When the “save condition” button 128 is selected, the confirmed setting is saved in a memory or the like. Furthermore, when the “call condition” button 130 is selected, a previously set condition can be called.

  Next, water supply is started at the timing when 30 minutes have elapsed after the start of measurement, and the water supply is stopped when 75 minutes have elapsed, and the target temperature is increased from 30 ° C. to 34 ° C. at the timing when 60 minutes have elapsed after the start of measurement. The operation of the characteristic evaluation apparatus 100 will be described more specifically by taking as an example a case where a sequence is set so as to lower the target temperature from 34 ° C. to 32 ° C. when minutes have elapsed. Needless to say, the present invention is not limited to these examples.

In order to execute this operation, the following first sequence to fourth sequence are set from the sequence setting screen described above.
(1) First sequence [resting state]
Start time 0 minutes Temperature setting Simulated skin surface temperature 30 ° C
Water supply OFF
(2) Second sequence [start sweating]
Start time 30 minutes after starting measurement Temperature setting Simulated skin surface temperature 30 ° C
Water supply ON
(3) Third sequence [skin temperature rise, sweating continued]
Start time 60 minutes after starting measurement Temperature setting Simulated skin surface temperature 34 ℃
Water supply ON
(4) Fourth sequence [skin temperature reduction, sweating stop]
Start time 75 minutes after starting measurement Temperature setting Simulated skin surface temperature 32 ° C
Water supply OFF

  The display example shown in FIG. 3 described above shows the setting of the first sequence. In the setting of the first sequence, “0” time “0” minutes are input in the elapsed time input field 116, “control in temperature value” is selected in the thermal control method input field 118, and “ “Stop” is selected, and “30.0” ± “0.5” ° C. is entered in the thermal control operation input field 122. Similarly, the second to fourth sequences are set. Note that the setting method of the second to fourth sequences is the same as that of the first sequence, and thus description thereof is omitted here.

  Subsequently, according to the set conditions, the first sequence to the fourth sequence are automatically and sequentially executed, so that the actual skin condition is reproduced in a simulated manner. Moisture movement is simulated.

Here, the operation results and measurement results of the characteristic evaluation apparatus 100 when the first to fourth sequences are executed are shown in FIGS. FIG. 4A is a graph showing the time course of the simulated skin temperature, the horizontal axis is the elapsed time (minutes) from the start of measurement, and the vertical axis is the simulated skin temperature (° C.). FIG. 4B is a graph showing the change over time of the simulated skin heat flow, the horizontal axis is the elapsed time (minutes) from the start of measurement, and the vertical axis is the simulated skin heat flow (W / m ² ). FIG. 4 (c) is a graph showing the change over time in the clothing temperature, the horizontal axis is the elapsed time (minutes) from the start of measurement, and the vertical axis is the clothing temperature (° C.). FIG. 4D is a graph showing the change over time in the clothes humidity, the horizontal axis is the elapsed time (minutes) from the start of measurement, and the vertical axis is the clothes humidity (% RH).

  The first sequence is executed until 30 minutes have elapsed from the start of measurement, the surface temperature of the simulated skin member 10 is adjusted to 30 ° C., the drive of the pump 54 is stopped, and water supply is stopped. Therefore, the simulated skin temperature is maintained at approximately 30 ° C. as shown in FIG. Further, during the execution of the first sequence, as shown in FIGS. 4B to 4D, the simulated skin heat flow, the temperature in the clothes, and the humidity in the clothes are kept substantially constant. During the execution of the first sequence, the electronic control unit 40 performs feedback control by, for example, a known PID calculation so that the set target temperature matches the actual surface temperature of the simulated skin member 10 detected by the temperature sensor 18. I do. Note that, by changing the setting of the sequence, feedback control can be performed so that the heat flow rate detected by the heat flux sensor 20 matches the target heat flux. Further, the feedback control may be executed in consideration of the actual temperature and the temperature difference detected by each temperature sensor 18 in addition to the heat flux detected by the heat flux sensor 20.

  When 30 minutes have elapsed after the start of measurement, the second sequence is executed. In the second sequence, the pump 54 is driven to supply water to the surface of the simulated skin member 10. As a result, as shown in FIG. 4D, the humidity in the clothes increases. Here, the water absorption, hygroscopicity, moisture permeability, etc. of the fabric can be evaluated from the rising angle of the humidity in the clothes. In addition, it is possible to evaluate the easiness of moisture accumulation from the height of the peak value and the peak maintenance time.

  Subsequently, the third sequence is executed when 60 minutes have elapsed after the start of measurement. In the third sequence, the target temperature is changed from 30 ° C. to 34 ° C. while the drive of the pump 54 is maintained. Here, as described above, the electronic control unit 40 feeds back the electric power supplied to the Peltier element 22 so that the set target temperature matches the actual surface temperature of the simulated skin member 10 detected by the temperature sensor 18. Control. Therefore, the simulated skin heat flow increases (see FIG. 4B) and the surface temperature of the simulated skin member 10 rises to approximately 34 ° C. (see FIG. 4A). As a result, the temperature in the clothes increases as shown in FIG. Here, the heat radiation characteristics / heat retention characteristics of the fabric can be evaluated from the rising angle of the temperature in the clothes, the peak height, and the peak maintenance time.

  When 75 minutes have elapsed after the start of measurement, the fourth sequence is executed. In the fourth sequence, the drive of the pump 54 is stopped and the target temperature is changed from 34 ° C. to 32 ° C. Therefore, the simulated skin heat flow is reduced (see FIG. 4B) and the surface temperature of the simulated skin member 10 is reduced to about 32 ° C. (see FIG. 4A). As a result, the temperature in the clothes decreases as shown in FIG. In addition, as shown in FIG. 4D, the humidity in the clothes decreases. Here, the heat dissipation characteristics / heat retention characteristics of the fabric can be evaluated from the descending angle of the temperature in the clothes. Further, the transpiration characteristics of the fabric can be evaluated from the descending angle of the humidity in the clothes. Thereafter, the measurement is automatically terminated when 90 minutes have elapsed since the start of the measurement.

  According to the present embodiment, the power supplied to the Peltier element 22 is feedback-controlled so that the set target temperature and the actual surface temperature of the simulated skin member 10 detected by the temperature sensor 18 coincide with each other. Since the temperature of the skin member 10 is adjusted in real time, it is possible to simulate a transient state in which the skin temperature changes with time.

  According to the present embodiment, the heat energy transmitted between the simulated skin member 10 and the Peltier element 22 without passing through the heat flux sensor 20 is blocked by the heat insulating member 30. As a result, almost all of the heat energy is transmitted through the heat flux sensor 20, so that the amount of heat energy transferred between the simulated skin member 10 and the Peltier element 22 is detected in real time and with high accuracy. be able to. Since the power supplied to the Peltier element 22 is adjusted based on the result detected in real time, the temperature of the simulated skin member 10 is adjusted in real time. It becomes possible to simulate with high accuracy.

  Further, according to the present embodiment, the surface temperature of the simulated skin member 10 is controlled by controlling the power supplied to the Peltier element 22 in consideration of the detection result of the temperature sensor 18 in addition to the detection result of the heat flux sensor 20. The amount of heat generated by the Peltier element 22 can be adjusted in consideration of unevenness. As a result, in this embodiment, the temperature unevenness on the surface of the simulated skin member 10 can be suppressed to within ± 0.5 ° C.

  According to the present embodiment, since the Peltier element is used as the thermoelectric conversion element, the simulated skin member 10 can be cooled as well as heated by switching the voltage application direction, and the amount of power supplied is adjusted. This makes it possible to accurately adjust the heating amount and the cooling amount.

  Furthermore, according to the simulated skin apparatus 1, the surface temperature of the simulated skin member 10 can be adjusted in real time as described above, and a transient state in which the skin temperature changes with time can be simulated. Therefore, according to the characteristic evaluation method according to the present embodiment, not only the steady state in which the skin surface temperature is kept constant, but also the physical characteristics of the fabric in the transient state in which the skin temperature changes over time. Is possible.

  Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made. For example, in the above-described embodiment, the case where the simulated skin apparatus 1 according to the present invention is applied to the fabric characteristic evaluation apparatus 100 has been described as an example. However, this is an example of the application, and the application to which the simulated skin apparatus is applied. It goes without saying that the invention is not limited to a fabric property evaluation apparatus.

  In the above embodiment, a copper plate or an aluminum plate is used as a member constituting the simulated skin member 10, but the material is not limited to copper or aluminum, and a member having a material with good thermal conductivity may be used. .

  Further, the number and arrangement of Peltier elements used in the simulated skin apparatus 1 and the number and arrangement of the heat flow rate sensors are not limited to the above-described embodiment, but may be changed as appropriate according to the required specifications of the simulated skin apparatus. Is preferred. Further, an electric heater or the like can be used instead of the Peltier element.
