Description

Technical Field

[0001] The present invention relates to a humidifier, and more particularly to a humidifier capable of simultaneously discharging purified air and humidified air. Background Art

[0002] To maintain a comfortable indoor environment, you can use a humidifier or air purifier. A humidifier is a device that vaporizes water and expel humidified air with high moisture content, while an air purifier is a device that filters foreign matter from the air in the indoor space and expel comfortable air.

[0003] In recent years, products that combine humidifiers and air purifiers have been produced.

[0004] However, a combined humidifier and air purifier may have a structure that discharges filtered and humidified air through a single outlet. In this case, the filtered and humidified air are discharged simultaneously, which has the advantage of improving indoor comfort. However, because the filtered and humidified air flow through the same flow path, a large amount of moisture may be retained in the discharge area. A flow path with high moisture content is troublesome and requires constant management to maintain internal cleanliness.

[0005] Korean Patent KR10-2463824 discloses a structure in which filtered air and humidified air are discharged together. In the above structure, the filtered air and humidified air are discharged through the same discharge port, so the above-mentioned trouble may occur. Summary of the Invention

[0024] The connecting pipe guide may be connected to the humidifying device at a lower side, and may supply humidified air generated in the humidifying device to the connecting pipe.

[0025] An air supply fan is arranged at the lower side of the humidifier, and an air supply flow path is formed between the water bucket and the main body to transport the air rising by the air supply fan to the first outlet, so that the air flowing by the air supply fan can be transported upward.

[0026] A water tank cover covering the upper side of the water tank is included, and the first discharge port may be formed along the outer circumference of the water tank cover.

[0027] The water tank cover is formed with a through hole for the connecting pipe to pass through, and the water tank cover can maintain the configuration of the connecting pipe.

[0028] A water supply hole for delivering water supplied from an upper side to the inner side of the water tank is formed at the center of the water tank cover. The water supply hole is formed at a lower position than the through hole, and water supplied to the water tank cover can flow into the water supply hole.

[0029] The main body includes an outer cover with a suction port formed on one side and an inner body arranged on the inner side of the outer cover. A lower opening is formed on the peripheral surface of the inner body to allow the filter to be introduced or led out. An upper opening that opens to the upper side can be formed on the upper surface of the inner body.

[0030] The inner body may include an inner wall defining a space for arranging the water tank and an outer wall arranged around the inner wall, wherein an air flow path for ascending air flowing from the air blowing fan is formed between the outer wall and the inner wall.

[0031] Specific matters of other embodiments are included in the detailed description and drawings.

[0032] Effects of the Invention

[0033] The humidifier according to the present invention has one or more of the following effects.

[0034] First, the first outlet for discharging the ventilation air or the air purification air and the second outlet for discharging the humidified air are separated in the vertical direction, which has the advantage of being able to separate the humidified air and the purified air and discharge them.

[0035] Second, the area where the air purification air flows and the area where the humidification air flows are separated, which also has the advantage of being able to manage the corresponding areas separately.

[0036] Third, since the air flowing by the blower fan is discharged at the lower side from which the humidified air is discharged, there is also an advantage that the humidified air can be diffused by the blower air.
