In addition, from the viewpoint of preventing water leakage of the atomizing element 112 due to excessive water pressure from the water tank 111, the water pressure at the water inlet of the atomizing element 112 is preferably 3 cm or less of water. The mist discharged from the atomizing element 112 preferably has a particle size of 3 to 10 μm, more preferably 4 to 6 μm, so that dew condensation on the surface of the vegetable and fruit can be prevented from occurring and the vegetable and fruit can be prevented from rotting. The pore size of the micro-pores of the micro-perforated plate of the atomizing element 112 can be determined based on the target particle size of the water mist.

Further, the water tank 111 is preferably provided on the cover 102 so as to be detachable from the cover 102, so that a user can take out the water tank 111 and add water to the humidifier 110. In addition, the water tank 111 may also be formed integrally with the cover plate 102, i.e., a recess for storing water is formed in the cover plate 102. In this case, a water filling port may be provided in the top of the recess, which is the water tank 111, and a lid may be provided on the water filling port. This also reduces the space occupied by the humidifier 110.

The above describes an example in which the humidifying device 110 has one water tank 111 and one atomizing element 112, respectively, but a plurality of water tanks 111 and/or a plurality of atomizing elements 112 may be provided as necessary. For example, the humidifying device 110 may include one water tank 111 and a plurality of atomizing elements 112, and the one water tank 111 and the plurality of atomizing elements 112 are connected by a plurality of water supply paths 114, so that the mist can be more uniformly diffused in the humidifying compartment 100.
