Abstract

A dust removing device includes: a dust position estimating unit which estimates a position of a dust area which is an area in which there is dust; an air blow determining unit which determines, based on the estimated position, an air blow mode which causes a predetermined airflow in the dust area; an air blower which performs an air blow in the determined air blow mode; and an air intake unit which takes in air from a space in which the air blow is performed. Note that the dust removing device may include an information storage which stores a control table in which air blow control information defining the air blow mode is written for a position of each dust area, and the air blow determining unit may determine, based on the control table, the air blow mode in accordance with the air blow control information corresponding to the estimated position of the dust area.

First claim

What is claimed is:

1 . A dust removing device comprising:
a dust position estimator which estimates a position of a dust area in which there is dust; an air blow determiner which determines, based on the estimated position of the dust area, an air blow mode which causes a predetermined airflow in the dust area; an air blower which performs an air blow in the determined air blow mode; and an air intake which takes in air from a space in which the air blow is performed.

2 . The dust removing device according to claim 1 , further comprising an information storage which stores a control table which includes air blow control information indicating the air blow mode for each position of each potential dust area,
wherein the air blow determiner determines the air blow mode in accordance with the air blow control information based on the estimated position of the dust area by referring to the control table.

3 . The dust removing device according to claim 1 , wherein the air blow determiner determines, based on the estimated position, at least one of a first air blow mode which disperses dust and a second air blow mode which leads the dispersed dust to the air intake, and
the air blower performs an air blow in the first air blow mode and performs an air blow in the second air blow mode after performing the first air blow.

4 . The dust removing device according to claim 3 , further comprising an information storage which stores a control table that includes air blow control information indicating at least one of the first air blow mode and the second air blow mode for each position of each potential dust area in each potential configuration pattern in the space,
wherein the air blow determiner obtains a configuration pattern in the space in which the air blow is performed and determines at least one of the first air blow mode and the second air blow mode in accordance with the air blow control information based on the obtained configuration pattern and the estimated position of the dust area by referring to the control table.

5 . The dust removing device according to claim 1 , wherein
the dust position estimator detects local states related to dust concentration in different places in the space, and estimates the position of the dust area based on the detected local states.

6 . The dust removing device according to claim 5 , wherein
the local state is a dust concentration, and the dust position estimator determines, as the position of the dust area, a position at which the dust concentration is not less than a predetermined threshold.

7 . The dust removing device according to claim 5 , wherein
the local state is presence of a person, and the dust position estimator determines, as the position of the dust area, at least one of a position at which there is a person and a position at which the person was in a predetermined period of time.

8 . The dust removing device according to claim 5 , wherein
the air blower performs preliminary air blows, while changing air blow directions, before the air blow determiner determines the air blow mode, the dust position estimator detects a dust concentration of air taken in by the air intake for a direction of each preliminary air blow, and determines, as the position of the dust area, a position which corresponds to the direction in which the detected dust concentration is highest, and the air blow determiner determines the direction of the air blow to be the direction in which the dust concentration is highest.

9 . A method for removing dust, comprising:
estimating a position of a dust area in which there is dust; determining an air blow mode which causes a predetermined airflow in the dust area, based on the estimated position of the dust area; performing an air blow in the determined air blow mode; and taking in air from a space in which the air blow is performed.

10 . The dust removing device according to claim 5 , further comprising a statistic information obtainer which obtains a statistically recorded position of a person,
wherein the dust position estimator detects the local state based on the statistically recorded position of the person.

11 . The dust removing device according to claim 10 , wherein the statistic information obtainer further obtains statistically recorded behavior of a person, and the dust position estimator detects the local state based on the statistically recorded behavior triggering dust to fly up.
