Abstract

To provide a perspiration mannequin in which both a device volume and an area are reduced.SOLUTION: Water fed from a feeding pump 11 is supplied to manifolds corresponding to each portion of a mannequin main body from a feeding pipe 21. A proportional solenoid valve 14 is provided on the front stage of the manifold, and is structured to keep a water supply pressure constant. Moisture corresponding to a perspiration amount is supplied to each of the portions via a multicore wire from each of the manifolds. The multicore wire has a structure such that a large number of metal having a fine diameter are twisted, and communicates inside and outside of the manifold. A pressure set in the proportional solenoid valve 14 is a pressure necessary for pressure-feeding predetermined amount of water corresponding to the perspiration amount from the multicore wire. Due to the structure, a liquid driving source is one pump, and a device volume and surface property become remarkably small. When a pressure applied to the multicore wire is set to such a size as to ignore a water head difference, moisture is supplied to each of the portions with substantially an equal pressure irrespective of the water head difference and is subjected to perspiration, and the perspiration amount becomes substantially an equal in each of the portions.SELECTED DRAWING: Figure 2

Description

  The present invention relates to a sweating mannequin, and more particularly to a sweating mannequin in which the amount of sweating does not depend on the head difference.

  With the revolutionary progress of textiles, the clothing function has also improved dramatically. On the other hand, in order to evaluate the function of the clothes, a simulated human body (thermal) that can reproduce the heat generation and sweating of the human body according to the state of the outside air (temperature and humidity) or according to the situation such as sleeping or active. Mannequins) have been used.

  The heat generation mechanism can be realized by controlling a heater embedded under the artificial skin of the mannequin, but various configurations have been proposed for controlling perspiration.

  FIG. 8 shows an example. The mannequin main body 1 is divided into a plurality of parts A (Aa, Ab...), And water corresponding to the amount of perspiration is sent to each part from the liquid supply system having the following structure.

An electric piston burette 90 (90a, 90b,...) Is arranged corresponding to each part A, and water corresponding to the amount of perspiration from each piston burette 90 flows through the liquid supply pipe 91 (91a, 91b,...). Via the distribution connector 93 (93a, 93b,...). A sweat hole S (Sa, Sb,...) Is provided in each part A for each predetermined area (for example, 30 cm ² ), and is further branched from the distribution pipe 93 and distributed to each sweat hole S.

  In the above configuration, since the piston burette 90 is used corresponding to each part A in order to equalize the amount of perspiration in each part, there is a disadvantage that the device volume and area are large, and the cost is also high.

  The present invention has been proposed in view of the above-mentioned conventional circumstances, and an object of the present invention is to provide a sweating mannequin with reduced device volume and area.

  The following means of the present invention are adopted.

  The water sent from the liquid feed pump is supplied from a liquid feed pipe to a manifold corresponding to each part of the mannequin main body. A proportional solenoid valve is provided in front of the manifold to maintain a constant water supply pressure.

  Moisture corresponding to the amount of perspiration is supplied to each part from each of the manifolds via a multi-core wire. The multi-core wire has a structure in which a large number of thin metal pieces are brought together and communicates inside and outside the manifold. The pressure set in the proportional solenoid valve is a pressure required to pump a predetermined amount of water corresponding to the amount of sweat from the multifilamentary wire.

  The multi-core wire held by the solenoid valve may become clogged and may need to be replaced. Therefore, the unused multi-core wire is plugged, and when necessary, the plug is removed so that the multi-core wire can be replaced with the plugged multi-core wire.

  With the above configuration, the number of liquid drive sources is one, and the bulk and area of the apparatus are significantly reduced. In addition, if the pressure applied to the multifilament wire is set to such a level that the head difference can be neglected, moisture will be supplied to each part with substantially equal pressure regardless of the head difference, and it will be subjected to perspiration. The amount of perspiration is substantially equal in each part.

The figure for deciding the set pressure of a proportional solenoid valve. The figure which shows the conventional liquid supply system to the main body during perspiration.

  FIG. 1 is a configuration diagram of a sweating mannequin to which the present invention is applied.

  The mannequin main body 1 is made of metal or plastic, and a pseudo skin layer is formed on the surface. The pseudo skin layer is provided with a heat generating mechanism for generating heat corresponding to body temperature, and further provided with a sweating mechanism for discharging moisture evaporating from human skin or water corresponding to sweat from the surface of the pseudo skin layer.

  The simulated skin layer is divided into a plurality of parts A (Aa, Ab...) (19 divisions in the example of FIG. 1). The amount of perspiration by the mechanism is controlled by a liquid sending system 3 described below. Further, a control means 4 using a personal computer or the like for controlling the whole of the heat generation control circuit 2 and the liquid feeding system 3 is provided. The state of the mannequin main body 1 (surface temperature, amount of perspiration) or the temperature, humidity, etc. of the environment is transmitted to the control means 4 to be subjected to the heat generation and perspiration control.

  FIG. 2 shows a water distribution circuit of the liquid feeding system 3 according to the present invention.

  The water from the tank 10 is sent out by the liquid sending pump 11 through the liquid sending pipe 21, and the distribution pipes 22 (22a, 22b,...) Corresponding to each part A (Aa, Ab,...) Of the mannequin main body 1. , And supplied from the distribution pipe 22 to the perspiration manifold 18 (18a, 18b,...). An opening / closing valve 16 (16a, 16b,...) For starting and stopping water supply is provided in front of each manifold 18, and it is determined whether or not the portion A corresponding to each manifold 18 is to be subjected to perspiration. can do.

  Drains 17 (17 a, 17 b,...) Are provided on the output side of each manifold 18, and water not subjected to perspiration through the drains 17 is returned to the tank 10 through the drain pipe 23.

  A proportional solenoid valve 14 is inserted between the drainage pipe 23 and a stage before the branch of the liquid supply pipe 21 from the liquid supply pump 11 to each manifold 18, and the water supply pressure of the liquid supply pipe 21 is set to a constant value. A pressure regulating device 15 is provided for maintaining the pressure.

  As will be described below, since it is necessary to drain water from the above mechanism during non-operation, the three-way valve 12 is inserted into the liquid supply pipe 21 between the pump 11 and the proportional solenoid valve 14 so that the liquid is supplied to the liquid supply side. The configuration is such that it can be switched to the side of the air pump 13 that sends air for bleeding.

  FIG. 3 schematically shows a circuit corresponding to one portion, and FIG. 4 shows a manifold used in the present invention.

  As shown in FIG. 4, the manifold 18 is implanted in the cylindrical tube 181 such that a large number of multi-core wires 31 (31a, 31b,...) Communicate with the inside and outside of the tube wall in the diameter direction of the cylindrical tube 181. It is the configuration that was done. Water is supplied to the cylindrical pipe 181 from the distribution pipe 22 distributed corresponding to each part A of the mannequin main body 1, where the water is temporarily stored and returned to the tank 10.

  The multi-core wire 31 has a structure of a predetermined diameter (about 1 mmφ) formed by combining a plurality of (for example, 15 to 20) thin tubular (for example, 0.1 mmφ) metal wires. The pipe wall is communicated inside and outside. Outside the wall of the cylindrical tube 181, a Tygon tube 32 (32 a, 32 b,...) Is connected to the multi-core wire 31 and guided to the relay connector 6. From the relay connector 6, one Tygon tube 33 is guided to one sweat hole S through the Tygon tubes 33 (33 a, 33 b,...) To the sweat holes S provided at the corresponding portions A.

As described above, since the multi-core wire 31 includes a plurality of thin metal wires, water cannot be sent to the Tygon tube 32 unless water is sent to the manifold 18 at a high water supply pressure. The pressure depends on the diameter and the number of the metal pipes to be used, but any pressure may be used as long as the difference in the discharge amount due to the head difference of the mannequin main body 1 can be ignored.
FIG. 5 and FIG. 6 show the pressure adjusting operation by the above configuration.

  First, the three-way valve 12 is set to a liquid sending state, the set pressure of the proportional solenoid valve 14 is set to a predetermined value (for example, 0.5 MPa), and the liquid sending pump 11 is operated. When the water pressure exceeds the set pressure while being sent to the on-off valve 16, the water returns to the tank 10 via the proportional solenoid valve 14 (the thick solid line in FIG. 5A).

  Here, when the on-off valve 16 corresponding to the portion A to be verified (may be all the portions) is opened, water is accumulated in each manifold 18 and reaches the drain 17. Close to complete water accumulation. (FIG. 5 (b)).

  Here, when the electromagnetic valve 16 corresponding to the portion A to be verified is opened as described above, water flows into the manifold 18 and is supplied to the corresponding portion A, so that the pressure in the liquid feed pipe 21 is reduced. Temporarily lower than the set value (gray in FIG. 5B). Then, the pressure adjusting means 15 is operated, and the proportional solenoid valve 14 is adjusted so as to reduce the amount of water returned to the drain pipe 23 to increase the pressure in the liquid feed pipe 21 to the set value. (FIG. 5C).

  Then, while water is being supplied to each part A (FIG. 6A), the supply of water to any part A (or to all parts) is stopped (one of the on-off valves 16a, 16b,...). When (or all) are closed, the pressure in the liquid feed pipe 21 rises rapidly (the thick solid line in FIG. 6B). In this case, the proportional solenoid valve 14 is opened to the drain pipe 23 side so that the pressure adjusting means 15 is operated and the pressure in the liquid feed pipe 21 is maintained at the set value (FIG. 6 (c). The pressure in the liquid pipe 21 can be kept constant.

  The set pressure of the proportional solenoid valve 14 is such that the head difference is negligible, and when using a multi-core wire 31 composed of 19 0.1 φ fine metal wires, 0.3 MPa or more. It is.

  FIG. 7 shows a case where the multi-core wire 31 is used, in which the horizontal axis represents the height from the ground, and the vertical axis represents the deviation of the discharge amount from each sweat hole at a predetermined time on the vertical axis. It shows the results with pressure. At 0.05 MPa (black diamond), the head difference appears in the deviation, and even at 0.1 MPa (black square), it shows an unstable state. A stable result is obtained at 0.3 MPa (black triangle).

  Since the multi-core tube 31 is formed of a tube having a very small diameter as described above, it is easily clogged. Therefore, the multi-core tube 31 not used is usually plugged, and when the multi-core tube 31 in use is clogged, the plug of the multi-core tube 31 that has not been used is removed and the Tygon tube 32 is connected. By doing so, we can respond.

    As described above, according to the present invention, only one pump is used as the liquid feeding drive source, so that both the bulk and the area of the apparatus can be significantly reduced. In addition, since a certain amount of sweating state can be ensured regardless of the head difference, it can be widely used for evaluating the performance of clothes.
