The upper tray 60 further includes a guide wall 63 separating the inner space of the tray body 62 and a guide hole 64 formed through the guide wall 63.

The guide wall 63 extends in one direction along the tray body 62. That is, the guide wall 63 extends in the circumferential direction and separates the inner space of the tray body 62 in the radial direction.

Accordingly, the inner space of the tray body 62 is separated into a water supply space 62a and a supply space 62b located radially inward from the water supply space 62a. In other words, the water supply space 62a is disposed closer to the inner side of the case 10 in which the suction part 12 is formed than the supply space 62b.

In this case, the water supply port 61 is formed in the water supply space 62a, and the supply port 65 is formed in the supply space 62b. That is, the water supply space 62a is a portion for receiving water to the water supply assemblies 54 and 55, and the supply space 62b corresponds to a portion for supplying water to the water supply filter 51.

As shown in FIG. 5, the guide wall 63 extends axially upward from the bottom surface of the tray body 62.

The first flow A is supplied from the lower tray 52 to the upper tray 60 and corresponds to the flow in the axial upper direction. That is, the first flow A may be understood as the flow by the feed water pump 55.

Water supplied to the water inlet 61 flows into the inner space of the upper tray 60. In detail, the water supply port 61 flows to the formed water supply space 62a, hereinafter referred to as a second flow B. The second flow (B) flows along the water supply space (62a), and corresponds to the flow in the circumferential direction.

In addition, the second flow B may correspond to a circumferential clockwise or counterclockwise direction depending on the position and number of the water inlets 61. In FIG. 6, the water inlet 61 is formed at one side of the upper tray 60 so that the second flow B is formed clockwise.

That is, the water does not flow into the supply space 62b until the water is received by the guide height h in which the guide hole 64 is formed in the water supply space 62a. Accordingly, predetermined water is accommodated in the water supply space 62a, and water may be accommodated up to the opposite side of one side where the water supply port 61 is formed.

In other words, the water supplied to the water inlet 61 may be uniformly distributed in the upper tray 60 along the second flow B. When water is received in the water supply space 62a by the guide height h, the water flows into the supply space 62b through the guide hole 64.

Hereinafter, this is called a third flow C, and the third flow C corresponds to a radially inward flow. That is, it corresponds to the flow from the water supply space 62a to the supply space 62b through the guide hole 64.

Water flowing into the supply space 62b flows to the humidification filter 51 through the supply port 65. Hereinafter, this is referred to as a fourth flow D, and the fourth flow D corresponds to a flow in an axial lower portion. That is, the fourth flow D may be understood as a flow by gravity.
