Abstract

An air cleaning module includes a filter, a fan, a light source unit, a housing and a guide structure. The fan is configured to provide a suction direction and a blowing direction of a fluid which are substantially aligned. The light source unit is arranged to be adjacent to the filter to emit a light toward the filter. The light having a property that sterilizes a contaminant source in a fluid. The housing includes a fluid passage space. The guide structure is arranged between the fan and the filter and configured to guide a fluid to move along a fluid passage path set by the guide structure. The filter and the light source unit are arranged in the fluid passage space such that the light source unit sterilizes a fluid as a fluid flows toward the light source unit.

Dependent claims

An air purifying device, comprising:

a housing including an inner space, wherein the housing comprises a bottom surface, a top surface facing the bottom surface, and a side wall connecting the bottom surface and the top surface;
a fan configured to provide a suction direction and a blowing direction of a fluid, wherein the fan includes a blowing port;
a filter configured to filter the fluid passing therethrough;
an inlet configured to introduce the fluid from an external space of the housing into the inner space of the housing;
an outlet configured to discharge the fluid from the inner space to the external space of the housing;
a light source arranged closer to the outlet than the inlet and comprising a plurality of light emitters;
a guide disposed in the housing and configured to provide a first region and a second region different from the first region, the first region including a fluid passage path and the second region provided in an area outside of the fluid passage path, the area extending along the side wall of the housing;
a sensor (i) provided in the second region having a lower flow rate of the fluid than a flow rate of the fluid in the first region, (ii) positioned between a first plane defined by the blowing port of the fan and a second plane defined by the filter, and (iii) configured to sense a material in the fluid, the sensor located to be deviated from the fluid passage path and the sensor disposed on the side wall of the housing;
a controller configured to control the light source and a number of rotations of the fan based on a detection result by the sensor;
and
a display configured to display a control state of the fan,
wherein the filter is disposed in the first region to filter the fluid passing through the fluid passage path.
