Air purifier
An air cleaner including a case comprising an upper surface and a side surface, a sensor to measure a degree of contamination of air introduced into the case, a round portion in a shape that is curved on the upper surface of the case, and a sensor air inlet on the round portion and through which air is introduced.
1 . An air cleaner comprising:
a case comprising an upper surface and a side surface;
a sensor unit to measure a degree of contamination of air introduced into the case;
a round portion that is curved between the upper surface of the case and the side surface of the case; and
a sensor air inlet, on the round portion, through which the air is introduced into the case,
wherein the sensor unit comprises a dust sensor, a gas sensor and a sensor cover, the sensor cover having a first cover in which the dust sensor is provided and a second cover in which the gas sensor is provided,
the first cover comprises:
a first inlet part having a first inlet port opened along a lateral direction of the case,
a first flow path part connected to the first inlet part so that air introduced through the first inlet port reaches the dust sensor, and
an accommodating portion connected to the first flow path part to accommodate the dust sensor,
a discharge hole corresponding to a discharge port of the dust sensor so that air discharged from the dust sensor is discharged to an outside of the sensor cover, and
a second cover comprises:
a second inlet part through which air is introduced so that the gas sensor measures a concentration of gas in the air, and
a second flow path part connected to the second inlet part so that the introduced air reaches the gas sensor.
2 . The air cleaner according to claim 1 , wherein
the sensor cover further comprises a connection member to connect the first cover and the second cover so that the first cover and the second cover are integrally formed.
3 . The air cleaner according to claim 1 , wherein
the first inlet part has a shape curved along the round portion.
4 . The air cleaner according to claim 1 , wherein
the first inlet part comprises a rib that forms a step inside the first inlet port to prevent foreign substances from being introduced into the first inlet port.
5 . The air cleaner according to claim 1 , wherein
one side of the accommodating portion is open such that the dust sensor is inserted therethrough.
6 . The air cleaner according to claim 1 , wherein the dust sensor comprises:
a casing;
a suction port on one side of the casing to allow the air to be introduced therethrough;
a dust sensing part inside the casing to measure the concentration of dust in the air; and
a discharge port on another side of the casing through which the air is discharged subsequent to the concentration of dust being measured by the dust sensing part.
7 . The air cleaner according to claim 6 , wherein
the dust sensor further comprises a fan inside the casing to suck the air into the suction port.
8 . The air cleaner according to claim 1 , wherein
the second inlet part has a shape curved along the round portion.
9 . The air cleaner according to claim 1 , wherein the case comprises:
a front surface, the upper surface, a back surface and the side surface having an outlet, the back surface having an inlet, a fan arranged to draw air through the inlet, and a filter arranged to filter the air drawn through the fan into the inlet.
