- the change (hydrophobicization) of the central portion of the second surface 12 to the second state is slower than that of the other portions, and the hydrophilicity is maintained until the end. Therefore, the water moves from the other portion to the central portion of the second surface 12, and the moisture collects in the central portion of the second surface 12.
- the central portion of the second surface 12 functions as a headrace and promotes the discharge of water to the outside of the moisture absorbing material 10.

- the first surface 11 is formed on the first layer 10A.
- the second surface 12 is formed on the third layer 10C.
- the third layer 10C is arranged closer to the second surface 12 (non-opposing surface) than the first layer 10A.
- the first layer 10A is an example of the first layer of the present invention.
- the third layer 10C is an example of the second layer of the present invention.
- the temperature (phase transition temperature) at which the first layer 10A, the second layer 10B, and the third layer 10C change from the first state to the second state increases in this order. .. That is, the lower the moisture absorbing material 10, the higher the phase transition temperature. Therefore, the hydrophilicity becomes higher in the order of the first layer 10A, the second layer 10B, and the third layer 10C, and it becomes easier to absorb water.
- the phase transition temperature of the first layer 10A is 40 ° C.
- the phase transition temperature of the second layer 10B is 45 ° C.
- the phase transition temperature of the third layer 10C is 50 ° C.
- the lower limit of the temperature (phase transition temperature) at which the temperature changes from the first state to the second state is an example of the temperature at which the degree of hydrophilicity of the polymer compound becomes lower than a predetermined reference in the present invention.
- the moisture absorbing material 10 When the moisture absorbing material 10 is porous, it is desirable that the total surface area of all the pores decreases in the order of the first layer 10A, the second layer 10B, and the third layer 10C. Specifically, in the first layer 10A to the third layer 10C, the hole size may be reduced in the order of the first layer 10A, the second layer 10B, and the third layer 10C. In the first layer 10A to the third layer 10C, it is more desirable that the number of holes is reduced and the size of the holes is reduced in the order of the first layer 10A, the second layer 10B, and the third layer 10C. ..
- phase transition temperature The higher the temperature (phase transition temperature) at which the moisture absorbing material 10 changes from the first state to the second state, the higher the hydrophilicity and the easier it is to absorb water. Therefore, when heat is transferred, water is released first from the layer with the lower phase transition temperature, and water flows from the layer with the lower phase transition temperature to the adjacent layer (the layer with the higher phase transition temperature and higher hydrophilicity). Moving. For example, water moves from the first layer 10A to the second layer 10B. Therefore, the difference in the phase transition temperature or the gradient of the phase transition temperature can strongly promote the movement of water due to heat transfer and prevent the backflow of water.
- the hygroscopic material 10 when the hygroscopic material 10 is porous, the larger the surface area (the total surface area of all the holes), the more advantageous for moisture absorption. On the other hand, the smaller the surface area, the smaller the evaporation loss. Therefore, the smaller the surface area of the hygroscopic material 10, the easier it is to release water as liquid water when the second state is reached. Therefore, by reducing the surface area of the first layer 10A, the second layer 10B, and the third layer 10C in this order, the hygroscopic material 10 is heated to a predetermined heating temperature to release water from the hygroscopic material 10. The water contained in 10 can be effectively transferred from the first layer 10A to the third layer 10C through the second layer 10B as liquid water. As a result, the water collected in the third layer 10C can be effectively discharged as liquid water from the second surface 12 of the third layer 10C to the outside of the hygroscopic material 10 (see FIGS. 4A and 4B). ).
- the temperature for heating the heat conductive member 20 may be gradually increased from a temperature near the phase transition temperature of the first layer 10A to a temperature equal to or higher than the phase transition temperature of the third layer 10C. This makes it possible to reduce the water content (evaporation loss) that evaporates from the hygroscopic material 10 and cannot be accumulated and is lost. In other words, the efficiency of collecting liquid water can be further improved.
- the speed at which the temperature for heating the heat conductive member 20 is increased is determined by the thickness of the moisture absorbing material 10, the composition of the moisture absorbing material 10, the number of holes, the ratio of the volume occupied by the holes to the volume occupied by the bulk portion, and the like.
