Description

[0001] This invention relates to a humidifier, and more particularly, to a humidifier having a waterproof structure applied to a display.

[0002] A humidifier is a device that vaporizes water and emits humidified air with a high moisture content. A humidifier can generate humidified air by evaporating water through natural evaporation, heated evaporation, or ultrasonic vibration.

[0003] The 'upward discharge type large-capacity humidifier' disclosed in Korean Patent No. 10-2500340 includes a water tank for storing water; and a main body that is disposed on an upper side of the water tank and has a discharge hole formed in the upper side, wherein the main body includes a water storage space where supplied water is temporarily stored; a vibrator disposed on the bottom surface of the water storage space; a display disposed on an exterior wall; and a machine room formed in a lower side of the water storage space.

[0004] In the conventional humidifier, since the display is disposed on the peripheral wall of the main body forming the water storage space, there is a problem in that it is difficult to electrically connect to the machine room so as to supply power to the display.

[0005] In addition, since the display is disposed on the peripheral wall of the main body forming the water storage space, there is a risk of electric leakage from the display to the water stored in the water storage space. At this time, there is a problem of causing damage to user's body.

[0008] The invention may further provide a humidifier having a reduced risk of flooding.

[0009] The invention may further provide a humidifier with a reduced risk of short circuit.

[0010] The invention may further provide a humidifier having improved safety in use.

[0011] In accordance with an aspect of the present invention, a humidifier includes a molding member filled between the display substrate and the humidifying device, thereby protecting a display from moisture.

[0012] The humidifier further includes: a case which accommodates the humidifying device and the display; and a water tank which is disposed on an upper side of the humidifying device, and stores water, wherein the case includes: an outer shell which is spaced outward from the water tank; and an inner shell which is disposed inside the outer shell, and in which the water tank is accommodated therein, wherein a first discharge flow path through which humidified air flows is formed between the inner shell and the water tank, and the display is disposed outside the inner shell, so that the display may be isolated from the discharge flow path through which humidified air flows.

[0013] The humidifier further includes: a blowing fan which is disposed on a lower side of the humidifying device and forms a rising airflow, the case includes an outer case which extends downward from the outer shell, and in which the humidifying device and the blowing fan are disposed, wherein a blowing flow path is formed between the humidifying device and the outer case, and the display is disposed on the blowing flow path, so that dry air flowing through the blowing flow path can pass through the display.

[0014] The humidifier further includes: an electrical equipment unit which is disposed on a lower side of the humidifying device and supplies power, the main housing includes a housing recess recessed upward from a lower surface, wherein the housing recess is located above a lower surface of the display housing, and a first communication opening is formed between the housing recess and the lower surface of the display housing, so that the first communication opening may be spaced apart from the flow path of humidified air.

[0015] The electrical equipment unit includes: a power supply unit that supplies power; and an electrical equipment housing in which the power supply unit is accommodated, wherein the electrical equipment housing includes a wire hole which is located in a lower side of the housing recess, and opened upward, so that the wire connected to the electrical equipment unit may be connected to the display through the wire hole.

[0016] The humidifying device includes: a first valve which controls an amount of water inflow; and an accommodation space in which the first valve is disposed, wherein the humidifying device has a second communication opening which is formed to communicate the accommodation space with an internal space of the display housing, so that the wire may be connected to the first valve through the first communication opening and the second communication opening.
