Abstract
A dustproof apparatus according to an embodiment of the present technology includes a casing portion, a fan portion, a sensor unit, and a control unit. The casing portion is capable of accommodating an image display apparatus and includes an inlet and an outlet that discharges air sucked in from the inlet. The fan portion is provided at the outlet or the inlet. The sensor unit is capable of respectively measuring a first temperature which is a temperature of the air in a vicinity of the inlet and a second temperature which is a temperature of the air in a vicinity of the outlet. The control unit controls drive of the fan portion on a basis of a temperature difference between the first temperature and the second temperature measured by the sensor unit.
Claims10
A dustproof apparatus, comprising:
- a casing that is capable of accommodating an image display apparatus and includes an inlet and an outlet that discharges air sucked in from the inlet;
- a fan that is provided at the outlet or the inlet;
- a sensor capable of respectively measuring a first temperature which is a temperature of the air in a vicinity of the inlet and a second temperature which is a temperature of the air in a vicinity of the outlet;
- and
- control circuitry configured to control drive of the fan on a basis of a temperature difference between the first temperature and the second temperature measured by the sensor,
- wherein the control circuitry is further configured to control the drive of the fan on a basis of a change in the temperature difference, and
- wherein the control circuitry stops the drive of the fan in a case in which, while the fan is driven, a reduction amount of the temperature difference per unit time becomes equal to or larger than a predetermined threshold value.
An image display system, comprising:
- an image display apparatus;
- and
- a dustproof apparatus including
- a casing that is capable of accommodating the image display apparatus and includes an inlet and an outlet that discharges air sucked in from the inlet,
- a fan that is provided at the outlet or the inlet,
- a sensor capable of respectively measuring a first temperature which is a temperature of the air in a vicinity of the inlet and a second temperature which is a temperature of the air in a vicinity of the outlet, and
- control circuitry configured to control drive of the fan on a basis of a temperature difference between the first temperature and the second temperature measured by the sensor,
- wherein the control circuitry is further configured to control the drive of the fan on a basis of a change in the temperature difference, and
- wherein the control circuitry stops the drive of the fan in a case in which, while the fan is driven, a reduction amount of the temperature difference per unit time becomes equal to or larger than a predetermined threshold value.
A control method, comprising:
- measuring, by a sensor, a first temperature which is a temperature of air in a vicinity of an inlet of a dustproof apparatus capable of accommodating an image display apparatus and a second temperature which is a temperature of air in a vicinity of an outlet of the dustproof apparatus that discharges air sucked in from the inlet;
- and
- controlling, by circuitry, drive of a fan portion provided at the outlet or the inlet of the dustproof apparatus on a basis of a temperature difference between the measured first temperature and second temperature,
- wherein the controlling further comprises controlling the drive of the fan on a basis of a change in the temperature difference and stopping the drive of the fan in a case in which, while the fan is driven, a reduction amount of the temperature difference per unit time becomes equal to or larger than a predetermined threshold value.
