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 innovative progress of textiles, the fashion function has also improved dramatically. On the other hand, in order to evaluate the function of the clothing, 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, humidity), or according to the situation such as sleeping or active. Mannequins) are being used.

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

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

An electric piston burette 90 (90a, 90b ...) Is arranged corresponding to each portion A, and water corresponding to the amount of sweating from each piston burette 90 connects the liquid feeding pipe 91 (91a, 91b ...). It is sent to the relay connector 92 via the relay connector 92, and is sent from the relay connector 92 to each part A via the distribution pipe 93 (93a, 93b ...). Sweat holes S (Sa, Sb ...) Are provided in each portion A for each predetermined area (for example, 30 cm ² ), and are 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 for the purpose of making the amount of sweating in each part uniform, there is a drawback that both the device volume and the area are large and therefore the cost is 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 having a small device volume and area.

The following means of the present invention are adopted.

The water discharged from the liquid feed pump is supplied from the liquid feed pipe to the manifold corresponding to each part of the mannequin 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 sweating is supplied from each of the manifolds to each portion via a multi-core wire. The multi-core wire has a structure in which a large number of metals having a small diameter are brought together to communicate with each other inside and outside the manifold. The pressure set in the proportional solenoid valve is the pressure required to pump a predetermined amount of water corresponding to the amount of sweating from the multi-core wire.

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

With the above configuration, the liquid drive source is one pump, and the volume and area of the device are significantly reduced. In addition, if the pressure applied to the multi-core wire is set so that the head difference can be ignored, water will be supplied to each part at a substantially uniform pressure regardless of the head difference, and it will be used for sweating, as a matter of course. The amount of sweating is almost equal in each part.

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

The mannequin body 1 is made of metal or plastic, and a pseudo-skin layer is formed on the surface thereof. The pseudo-skin layer is provided with a heat generation mechanism that generates heat corresponding to body temperature, and is provided with a sweating mechanism that emits water evaporating from human skin or water corresponding to sweat from the surface of the pseudo-skin layer.

The pseudo-skin layer is divided into a plurality of parts A (Aa, Ab ...) (19 divisions in the example of FIG. 1), and for each part A, the amount of heat generated by the heat generation mechanism is generated by the heat generation control circuit 2 and sweating. The amount of sweating by the mechanism is controlled by the liquid feeding system 3 described below. Further, a control means 4 using a personal computer or the like that controls the entire heat generation control circuit 2, the liquid feeding system 3, and the like is provided. It goes without saying that the state of the mannequin body 1 (surface temperature, sweating amount), the temperature of the environment, the humidity, etc. are transmitted to the control means 4 and used for the heat generation and sweating 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 feed pump 11 via the liquid feed pipe 21, and the distribution pipe 22 (22a, 22b ...) Corresponding to each part A (Aa, Ab ...) Of the mannequin body 1 Is distributed to the sweating manifold 18 (18a, 18b ...) From the distribution pipe 22. An on-off valve 16 (16a, 16b ...) For starting and stopping water supply is provided in the front stage of each manifold 18, and it is determined whether or not the portion A corresponding to each manifold 18 is subject to sweating. can do.

A drain 17 (17a, 17b ...) Is provided on the output side of each manifold 18, and water that has not been subjected to sweating through the drain 17 is returned to the tank 10 via the drain pipe 23.

A proportional electromagnetic valve 14 is inserted between the front stage of the branch of the liquid feed pipe 21 from the liquid feed pump 11 to each manifold 18 and the liquid drain pipe 23, and the water supply pressure of the liquid feed pipe 21 is set to a constant value. A pressure adjusting device 15 for keeping the value is provided.

As will be described below, since it is necessary to drain water from the above mechanism when the pump is not in operation, a three-way valve 12 is inserted into the liquid feeding pipe 21 between the pump 11 and the proportional solenoid valve 14, and the liquid feeding side and water are inserted. It is configured so that it can be switched to the air pump 13 side that sends the air for bleeding.

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

As shown in FIG. 4, the manifold 18 is planted in the cylindrical tube 181 so that a large number of multi-core wires 31 (31a, 31b ...) Communicate inside and outside the tube wall in the radial direction of the cylindrical tube 181. It has become a structure. Water is supplied to the cylindrical pipe 181 from the distribution pipe 22 distributed corresponding to each portion A of the mannequin main body 1, where it is temporarily stored and returned to the tank 10.

The multi-core wire 31 has a structure having a predetermined diameter (about 1 mmφ) in which a plurality of thin tubular (for example, 0.1 mmφ) metal wires (for example, 15 to 20) are combined to form a cylindrical tube 181. Communicate the pipe wall inside and outside. Outside the tube wall of the cylindrical tube 181 the Tygon tube 32 (32a, 32b ...) Is connected to the multi-core wire 31 and guided to the relay connector 6. From the relay connector 6, the Tygon tube 33 of 1 is guided to the sweat hole S of 1 to the sweat hole S provided in the corresponding portion A via the Tygon tube 33 (33a, 33b ...).

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

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

Here, when the on-off valve 16 corresponding to the part A (which may be all parts) to be verified is opened, water is accumulated in each manifold 18 and reaches the drain 17, where the on-off valve 16 is temporarily used. Closes and the accumulation of water is completed. (FIG. 5 (b)).

Here, when the solenoid 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 the same. It is temporarily lower than the set value (Gray in FIG. 5 (b)). Therefore, the pressure adjusting means 15 is activated, and the proportional solenoid valve 14 is adjusted so as to reduce the amount of water returned to the drain pipe 23, and the pressure in the liquid feed pipe 21 is raised to the set value. (Fig. 5 (c)).

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 (either of the on-off valves 16a, 16b ...). Or all) is closed, the pressure in the liquid feed pipe 21 suddenly rises (FIG. 6 (b) thick solid line). In this case, the proportional solenoid valve 14 opens toward the drain pipe 23 so that the pressure adjusting means 15 operates and the pressure in the liquid feeding pipe 21 is maintained at the set value (FIG. 6 (c), and the feeding pipe 21 is fed. 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 can be ignored, and when a multi-core wire 31 consisting of 19 fine metal wires of 0.1φ is used, it is 0.3 MPa or more. Is.

FIG. 7 shows a case where the multi-core wire 31 is used, and different discharges are made when the height from the ground is taken as the horizontal axis and the deviation of the discharge amount from each sweat hole in a predetermined time is taken as the vertical axis. It shows the result in pressure. At 0.05 MPa (black rhombus), the head difference appears in the deviation, and even at 0.1 MPa (black square), it shows an unstable state. Stable results are obtained at 0.3 MPa (black triangle).

Since the multi-core tube 31 is composed of a tube having a very small diameter as described above, it is easily clogged. Therefore, the multi-core tube 31 that is not used is normally plugged, and when the multi-core tube 31 that is in use is clogged, the plug of the multi-core tube 31 that has not been used until now is removed and the Tygon tube 32 is connected. By doing so, it can be dealt with.

As described above, since the present invention uses only one pump as the liquid feeding drive source, the volume and area of the device can be remarkably reduced. In addition, since a certain amount of sweating state can be secured regardless of the head difference, it can be widely used for evaluation of clothing performance and the like.
