Apparatus

The apparatus of the present disclosure comprises: a resin composition that releases a water-soluble substance; a support member that supports the resin composition; a tank body that accommodates the support member and a liquid; a supply port for supplying a liquid to the tank; and a discharge port that is provided below the supply port in a predetermined state and discharges the liquid from the tank. The resin composition is exposed from an opening provided in the support member, and the distance between the supply port and the resin composition is shorter than the distance between the discharge port and the resin composition. As a result, a device for appropriately discharging a water-soluble substance is provided. 本公开的设备包括：树脂组合物，其放出水溶性物质；支承构件，其支承所述树脂组合物；罐体，其收纳所述支承构件和液体；供给口，其向所述罐体供给液体；以及放出口，其在预定状态下设于比所述供给口靠下方的位置，从所述罐体放出液体。所述树脂组合物自设于所述支承构件的开口部暴露，所述供给口与所述树脂组合物的距离比所述放出口与所述树脂组合物的距离短。由此，提供适当地放出水溶性物质的设备。
