Therefore, even if the height of the first side wall 221 is increased to ensure the volume of the drain pan 20, it helps to reduce the obstruction of the drain pan 20 to the airflow at the first air outlet FK1.

In addition, according to the humidity control device 1 of the present embodiment, when the distance between the bottom end of the first incision QK1 and the top surface of the first side wall 221 is set to L1 and the height of the first side wall 221 is set to L2, it is preferably satisfied that 0.15≤L1/L2≤0.25. Therefore, as shown in FIG. 9 , when the drain pan 20 is slightly tilted relative to the horizontal plane (for example, tilted 1° relative to the horizontal plane) due to installation errors, the condensed water in the drain pan 20 can be prevented from overflowing from the first incision QK1.

The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned embodiments.

For example, in the above embodiment, the first side wall 221 has a first cutout QK1, and the second side wall 222 has a second cutout QK2, but it is not limited to this. Only one of the first cutout QK1 and the second cutout QK2 may be provided. For example, when the first air outlet FK1 is an air inlet and the second air outlet FK2 is an air outlet, the second side wall 222 may not have the second cutout QK2.

In addition, in the above embodiment, a step is formed between the bottom end of the second incision QK2 and the bottom of the second inner shell opening KK2, but it is not limited to this. An air guide portion may be formed at the bottom of the second inner shell opening KK2 similar to the bottom of the first inner shell opening KK1, and the end of the air guide surface of the air guide portion close to the second incision QK2 is roughly flush with the bottom end of the second incision QK2.

Furthermore, in the above embodiment, the first cutout QK1 and the second cutout QK2 each have a horizontal bottom surface, but the present invention is not limited thereto. The first cutout QK1 and the second cutout QK2 may be formed in a shape such as an arc shape without a horizontal bottom surface.

Furthermore, in the above-mentioned embodiment, in the length direction of the drain pan 20, the first air outlet FK1 and the second air outlet FK2 are arranged at the same position, and the first incision QK1 and the second incision QK2 are arranged at the same position, but it is not limited thereto. In the length direction of the drain pan 20, the first air outlet FK1 and the second air outlet FK2 may be offset from each other.

Furthermore, in the above-described embodiment, the inner shell 10B for heat insulation is provided in the outer shell 10A, but the present invention is not limited thereto, and the inner shell 10B may be omitted depending on circumstances.

Furthermore, in the above-described embodiment, the humidity control unit 30 has a dehumidification function, but the present invention is not limited thereto, and the humidity control unit 30 may have only a humidification function instead of a dehumidification function.

Furthermore, the humidity control unit 30 in the above-described embodiment may be combined with an air supply device for supplying air to the humidity control unit 30 to form an air handling system.

It should be understood that within the scope of the present invention, various parts in the embodiments can be freely combined, or various parts in the embodiments can be appropriately deformed or omitted.
