Abstract

Provided is a cyclone type humidifier and wet air purifier combination device using centrifugal force. The humidifier and purifier combination device includes: a main housing; a blower fan provided under a main housing; a bottom housing which is coupled to the main housing and has an air blowing port, a water level sensor, an ultrasonic vibrator and a circular fixing plate; first and second filters which are disposed in the circular fixing plate; an outer cylindrical body which is coupled to the circular fixing plate and has a discharge pipe and an air inlet; an inner cylindrical body which is coupled to the circular fixing plate and includes an air guide body having a funnel shape with an impurity discharge hole; and an air guide housing configured.

Claims

1. A cyclone type humidifier and wet air purifier combination device using centrifugal force, comprising:

a main housing provided with a rotating plate provided in a central portion of a top surface of the main housing;

a blower fan provided at a predetermined position outside the main housing or below the main housing, the blower fan blowing air by means of operation of a motor;

a bottom housing removably coupled to a lower end of the main housing, the bottom housing having at a predetermined position an air blowing port through which air drawn from the blower fan can be sent into the bottom housing, with a water level sensor provided at a position in a bottom surface of the bottom housing, an ultrasonic vibrator provided at another position in the bottom surface of the bottom housing, and a circular fixing plate fixed in a central portion of the bottom surface of the bottom housing, the circular fixing plate having;

a first insert depression formed in an outer circumferential part of the circular fixing plate;

a second insert depression formed in an inner circumferential part of the circular fixing plate;

a first coupling depression formed between the first insert depression and the second insert depression; and

a second coupling depression formed in a central portion of the fixing plate inside the second insert depression;

a first filter and a second filter respectively and removably disposed in the first coupling depression and the second coupling depression;

an outer cylindrical body removably fitted into the first insert depression, the outer cylindrical body including;

a discharge pipe coupled to a central portion of an upper surface of the outer cylindrical body, with an outlet formed in the discharge pipe;

a plurality of water passing notches formed in a circumferential edge of a lower end of the outer cylindrical body at positions spaced apart from each other at predetermined intervals; and

an air inlet formed in the lower end of the outer cylindrical body so that air drawn from the air blowing port is supplied into the outer cylindrical body;

an inner cylindrical body removably fitted into the second insert depression, the inner cylindrical body having a cylindrical shape that is open on upper and lower ends thereof, with a plurality of water passing notches formed in a circumferential edge of a lower end of the inner cylindrical body at positions spaced apart from each other at predetermined intervals, and an air guide body integrally provided on an inner circumferential surface of the inner cylindrical body, the air guide body having a funnel shape that is reduced in diameter from an upper end thereof to a lower end, with an impurity discharge hole formed in the lower end of the air guide body; and

an air guide housing provided on an outer circumferential surface of the outer cylindrical body, the air guide housing being configured such that air drawn from the air blowing port can be supplied into the air inlet of the outer cylindrical body after being mixed with fine water particles generated by the ultrasonic vibrator, wherein the air blowing port, the water level sensor and the ultrasonic vibrator are disposed in the air guide housing,

wherein water is contained in the outer cylindrical body, the inner cylindrical body and the air guide housing.

2. The cyclone type humidifier and wet air purifier combination device as set forth in claim 1, wherein the rotating plate includes a plurality of blades in a perimeter thereof, the blades radially extending outwards, and a plurality of through hole are formed in the rotating plate inside the blades.

3. The cyclone type humidifier and wet air purifier combination device as set forth in claim 1, wherein the first filter has a doughnut shape, and the second filter has a circular plate shape, wherein each of the first and second filters is configured so as to be removable from the circular fixing plate.

4. The cyclone type humidifier and wet air purifier combination device as set forth in claim 1, wherein an air flow guide plate is provided at a position adjacent to the air inlet between an inner circumferential surface of the outer cylindrical body and an outer circumferential surface of the inner cylindrical body so that a mixture of air drawn into the outer cylindrical body through the air inlet and the fine water particles can be rotated by centrifugal force.

5. The cyclone type humidifier and wet air purifier combination device as set forth in claim 1, wherein the air blowing port is closed by a partition wall protruding from the bottom surface of the bottom housing to a predetermined height and is open in an upper portion thereof so that air drawn from the blower fan can smoothly flow through the air blowing port and be prevented from being affected by the water stored in the bottom housing.

6. The cyclone type humidifier and wet air purifier combination device as set forth in claim 1, wherein the ultrasonic vibrator generates vibrations in the stored water and thus induces an ultrasonic atomization phenomenon so that atomized water makes contact with drawn air, thereby primarily removing pollutants from the drawn air.

7. The cyclone type humidifier and wet air purifier combination device as set forth in claim 1, wherein the air guide housing has a streamline shape to make a flow of air drawn from the air blowing port smooth.

8. The cyclone type humidifier and wet air purifier combination device as set forth in claim 1, wherein a water contamination sensor is provided in the air guide housing, the water contamination sensor checking whether the stored water is contaminated.

9. The cyclone type humidifier and wet air purifier combination device as set forth in claim 1, being configured to be adjusted in function in such a way that when an RPM of the motor is comparatively low, a humidifier function is conducted, and when the RPM of the motor is comparatively high, an air purifier function is conducted.

10. The cyclone type humidifier and wet air purifier combination device as set forth in claim 1, wherein a water discharge prevention ring is provided on an inner circumferential surface of the discharge pipe.
