Abstract

Disclosed is a slim-type air processing device adopting a centrifugal fan which is capable of air suction on both sides of the device. The disclosed slim-type air processing device comprises: a housing; a centrifugal fan provided inside the housing; an air suction part which is formed in the housing and is provided in the radial direction of the centrifugal fan; and an air processing part which is mounted in the housing, is disposed on a flow path of air flowing from the air suction part to the centrifugal fan, and processes air passing therethrough in a manner of at least one of dehumidification, humidification, and purification. According to the slim-type air processing device, it is possible to efficiently use the entire area of a filter, and to obtain an effect in which the device has a smaller size and has an improved design.

First claim

The invention claimed is:

1. A slim-type air processing device, comprising:
a housing;
a centrifugal fan provided inside the housing;
an air suction part formed in the housing; and
an air processing part mounted in the housing, disposed on a flow path of air flowing from the air suction part to the centrifugal fan, and processing air, passing therethrough, in a manner of at least one of dehumidification, humidification, and purification,
wherein the centrifugal fan is provided with a shaft parallel to a front-rear direction of the housing, and
the air suction part and the air processing part are provided on both sides of the housing,
wherein the centrifugal fan includes a first inlet disposed toward a front surface of the housing and a second inlet disposed toward a rear surface of the housing,
the air suction part includes a first air suction part formed in one side of the housing, and a second air suction part formed in the other side of the housing, and
an interior of the housing is provided with a first flow path connected from the first air suction part of the housing to the first inlet of the centrifugal fan, a second flow path connected from the first air suction part of the housing to the second inlet of the centrifugal fan, a third flow path connected from the second air suction part of the housing to the first inlet of the centrifugal fan, and a fourth flow path connected from the second air suction part of the housing to the second inlet of the centrifugal fan,
the slim-type air processing device further comprising:
a first opening and closing part provided in the housing and configured to open and close the first flow path;
a second opening and closing part provided in the housing and configured to open and close the second flow path;
a third opening and closing part provided in the housing and configured to open and close the third flow path; and
a fourth opening and closing part provided in the housing and configured to open and close the fourth flow path.

2. The slim-type air processing device of claim 1 , wherein an empty space is formed between an inlet of the centrifugal fan and an inner wall of the housing opposing the inlet.

3. The slim-type air processing device of claim 1 , wherein the air processing part includes an air purification filter.

4. The slim-type air processing device of claim 1 , wherein the centrifugal fan is configured to draw in air on both sides of the housing.

5. The slim-type air processing device of claim 1 , wherein an upper end of the housing is provided with an air discharge part from which air inside of the housing is discharged externally.

6. The slim-type air processing device of claim 1 , further comprising:
a gas sensor for sensing a gas concentration of air outside of the housing;
a dust sensor for sensing a dust concentration of air outside of the housing; and
a control part configured to control a flow path opening and closing operation of the first opening and closing part, the second opening and closing part, the third opening and closing part, and the fourth opening and closing part, based on a value sensed by the gas sensor and the dust sensor.

7. The slim-type air processing device of claim 6 , wherein the air processing part includes a first filter disposed in the first air suction part and having a deodorizing filter, and a second filter disposed in the second air suction part and having a HEPA filter, and
the control part allows the first opening and closing part and the second opening and closing part to be opened when a gas concentration, sensed by the gas sensor, is equal to or greater than a reference value, and
allows the third opening and closing part and the fourth opening and closing part to be opened when a dust concentration, sensed by the dust sensor, is equal to or greater than a reference value.

8. The slim-type air processing device of claim 7 , wherein the control part allows the first opening and closing part and the second opening and closing part to be closed when the gas concentration, sensed by the gas sensor, is lower than the reference value, and
allows the third opening and closing part and the fourth opening and closing part to be closed when the dust concentration, sensed by the dust sensor, is lower than the reference value.

9. The slim-type air processing device of claim 7 , wherein the control part allows the first opening and closing part and the second opening and closing part to be opened and the third opening and closing part and the fourth opening and closing part to be closed, when the gas concentration, sensed by the gas sensor, is equal to or greater than a preset reference value, and
allows the first opening and closing part and the second opening and closing part to be closed and the third opening and closing part and the fourth opening and closing part to be opened, when the dust concentration, sensed by the dust sensor, is equal to or greater than a preset reference value.

10. The slim-type air processing device of claim 1 , wherein the air processing part includes a first filter disposed in the first air suction part and purifying air and a second filter disposed in the second air suction part and purifying air, the first filter and the second filter having different air purification functions.

11. The slim-type air processing device of claim 10 , wherein the first filter includes a deodorizing filter removing an odor in air and the second filter includes a high efficiency particulate air (HEPA) filter removing fine dust and bacteria in air.
