## Abstract

The present disclosure relates to a humidifier. A humidifier according to one aspect of the present disclosure includes: a case with an intake opening; a fan disposed inside the case; a discharge opening positioned downstream of the fan; a humidification assembly including a humidification device disposed between the fan and the discharge opening, for spraying supplied water, and an outlet through which mist produced by the humidification device is discharged; and an impactor disposed between the outlet and the discharge opening, to which the mist discharged through the outlet is admitted. Thus, the droplet size of humidified air discharged through the discharge opening can be reduced.

## Claims

### Claim 1

A humidifier comprising:
a case with an intake opening;
a fan disposed inside the case;
a discharge opening positioned downstream of the fan;
a humidification assembly including a humidification device disposed between the fan and the discharge opening, for spraying supplied water, and an outlet through which mist produced by the humidification device is discharged; and
an impactor disposed between the outlet and the discharge opening, to which the mist discharged through the outlet is admitted.

### Claim 2 (depends on 1)

The humidifier of claim 1, wherein the mist discharged from the humidification assembly is discharged through the discharge opening after hitting the impactor.

### Claim 3 (depends on 1)

The humidifier of claim 1, wherein the impactor includes:
a lower body including a lower plate disposed above the outlet and a lower hole formed through the lower plate; and
an upper body including an upper plate disposed above the lower body and an upper hole vertically formed through the upper plate.

### Claim 4 (depends on 3)

The humidifier of claim 3, wherein the lower hole and the upper hole are alternately arranged in a circumferential direction of the impactor.

### Claim 5 (depends on 3)

The humidifier of claim 3, wherein the diameter of the lower hole is larger than the diameter of the upper hole.

### Claim 6 (depends on 3)

The humidifier of claim 3, wherein the lower hole vertically faces the upper plate, and the upper hole vertically faces the lower plate.

### Claim 7 (depends on 3)

The humidifier of claim 3, wherein the lower hole is vertically spaced apart from the upper plate, and the impactor includes a lower space formed between the lower hole and the upper plate.

### Claim 8 (depends on 3)

The humidifier of claim 3, wherein the impactor includes:
an outer wall that surrounds the upper plate; and
an upper space surrounded by the outer wall and formed above the upper hole.

### Claim 9 (depends on 1)

The humidifier of claim 1, wherein the impactor includes:
a first lower body including a first lower plate disposed above the outlet and a first lower hole formed through the first lower plate;
a first upper body attached to the top of the first lower body and including a first upper hole which is vertically formed;
a second lower body attached to the top of the first upper body and including a second lower hole which is vertically formed; and
a second upper body attached to the top of the second lower body and including a second upper hole which is vertically formed.

### Claim 10 (depends on 9)

The humidifier of claim 9, wherein mist that has passed through the first upper hole is admitted into the second lower body through the second lower hole.

### Claim 11 (depends on 9)

The humidifier of claim 9, wherein the diameter of the first lower hole is larger than the diameter of the second lower hole.

### Claim 12 (depends on 1)

The humidifier of claim 1, comprising:
a water reservoir disposed inside the case, for storing water supplied to the humidification assembly; and
a humidification flow path formed between the outlet and the discharge opening and surrounding the water reservoir,
wherein the impactor is disposed in the humidification flow path in such a way as to surround the water reservoir.

### Claim 13 (depends on 12)

The humidifier of claim 12, wherein the water reservoir includes:
a bucket forming a space for storing water; and
a bucket housing for holding the bucket,
wherein the impactor is positioned below the bucket.

### Claim 14 (depends on 12)

The humidifier of claim 12, wherein the water reservoir includes a guide rim protruding toward the humidification flow path and positioned above the outlet,
wherein the impactor is seated on the top of the guide rim.

### Claim 15 (depends on 1)

The humidifier of claim 1, wherein the impactor includes:
a lower plate disposed above the outlet; and
a lower hole vertically formed through the lower plate and extending in a circumferential direction of the lower plate.

### Claim 16 (depends on 1)

The humidifier of claim 1, wherein the impactor includes:
a lower body disposed above the outlet and including a lower hole which is vertically formed;
an upper plate disposed above the lower body;
an outer wall spaced radially outward from the upper plate;
an upper rim spaced radially inward from the upper plate;
an outer bridge connecting the upper plate and the outer wall;
an inner bridge connecting the upper plate and the upper rim;
an outer hole formed between the upper plate and the outer wall; and
an inner hole formed between the upper plate and the upper rim.

### Claim 17 (depends on 16)

The humidifier of claim 16, wherein the outer hole and the inner hole are spaced apart from each other radially of the impactor, and the lower hole, positioned between the outer hole and the inner hole, faces the upper plate.

### Claim 18 (depends on 1)

The humidifier of claim 1, wherein the impactor includes:
a lower body including a lower plate disposed above the outlet and a lower hole vertically formed through the lower plate;
an upper plate disposed above the lower body;
an inner hole vertically formed through the upper plate and positioned further radially inward of the impactor than the lower hole; and
an outer hole vertically formed through the upper plate and positioned further radially outward of the impactor than the lower hole.

### Claim 19 (depends on 18)

The humidifier of claim 18, wherein the inner hole is formed to bulge radially inward of the impactor, and the outer hole is formed to bulge radially outward of the impactor.

### Claim 20

A humidifier comprising:
a case with an intake opening;
a fan disposed inside the case;
a discharge opening positioned downstream of the fan;
a water reservoir disposed inside the case in such a way as to be pulled out, and internally having a space for storing water;
a humidification assembly that sprays water supplied from the water reservoir;
a humidification flow path that connects the humidification assembly and the discharge opening and is formed to surround the water reservoir; and
an impactor into which mist produced in the humidification assembly is admitted, and that is disposed in the humidification flow path in such a way as to surround the water reservoir.
