Humidifier

A humidifier comprising a water circuit 20 which has a first heat exchanger 32 and a second heat exchanger 42 connected thereto and through which either water of cold water and hot water flows, the first heat exchanger 32 and the second heat exchanger 42 each having an adsorbent and adsorbing moisture in air and desorbing the moisture to discharge the moisture into the air, wherein:

• the water circuit 20 switches flow of the water between a first flow state, in which the water introduced from an inlet 21 flows through the first heat exchanger 32 and flows to an outlet 22 and a second flow state, in which the water introduced from the inlet 21 flows through the second heat exchanger 42 and flows to the outlet 22, and adsorbs and desorbs the moisture alternately by the first heat exchanger 32 and the second heat exchanger 42;
• and
• the water circuit 20 has a bypass passage for connecting the inlet 21 to the outlet 22 at a time of switching the flow of the water.

A humidifier comprising a water circuit 20 which has a first heat exchanger 32 and a second heat exchanger 42 connected thereto and through which waters of cold water and hot water flow, the first heat exchanger 32 and the second heat exchanger 42 each having an adsorbent and adsorbing moisture in air and desorbing the moisture to discharge the moisture into the air,

• wherein the water circuit 20 has switching means 31, 33, 41, and 43 for switching flow of the water between a first flow state, in which the hot water introduced from a first inlet 21 flows through the first heat exchanger 32 and flows to a first outlet 22 and in which the cold water introduced from a second inlet 23 flows through the second heat exchanger 42 and flows to a second outlet 24, and a second flow state, in which the hot water introduced from the first inlet 21 flows through the second heat exchanger 42 and flows to the first outlet 22 and in which the cold water introduced from the second inlet 23 flows through the first heat exchanger 32 and flows to the second outlet 24, and adsorbs and desorbs the moisture alternately by the first heat exchanger 32 and the second heat exchanger 42, characterized in that the water circuit 20 has buffer tanks 39, 49 of the cold water and the hot water disposed upstream of the outlet side switching means 33, 43.
