Abstract
A blower includes a fan, an inlet through which air is drawn into the fan, and an outlet through which an air flow from the fan is exhausted. The inlet and the outlet have slits with a specific width or an array of through holes with a specific diameter. The relationship A<C, A<B is satisfied, where A represents the width of the slits or the diameter of the through holes of the inlet, B represents a particle size of dust that is allowed to pass through in view of the dust-proof performance of the fan, and C represents the width of the slits or the diameter of the through holes of the outlet. The blowing performance can be improved within the range of dust-proof performance in which damage or functional degradation can be avoided.
Claims12
A blower comprising:
- a fan;
- an inlet through which air is drawn into the fan;
- and
- an outlet through which an air flow from the fan is exhausted,
- wherein the inlet and the outlet have slits with a specific width or an array of through holes with a specific diameter, and
- the following relationship is satisfied:
- A<C,A<B
- where A represents the width of the slits or the diameter of the through holes of the inlet, B represents a particle size of dust that is allowed to pass through in view of dust-proof performance of the fan, and C represents the width of the slits or the diameter of the through holes of the outlet.
An electric apparatus comprising:
- a partitioned chamber that is formed by separating an inside of a main unit case with a partition;
- a heat-exchange element that is located in the partitioned chamber;
- and
- a blower that is located in the partitioned chamber to send air to the heat-exchange element,
- wherein the blower comprises:
- a fan;
- an inlet communicating with the partitioned chamber, through which outside air is drawn and sent by the fan;
- and
- an outlet communicating with the partitioned chamber, through which an air flow sent from the fan is exhausted,
- wherein the inlet and the outlet have slits with a specific width or an array of through holes with a specific diameter, and
- the following relationship is satisfied:
- A<C,A<B
- where A represents the width of the slits or the diameter of the through holes of the inlet, B represents a particle size of dust that is allowed to pass through in view of dust-proof performance of the fan, and C represents the width of the slits or the diameter of the through holes of the outlet, and
- wherein the heat-exchange element is located between the fan and the outlet.
An electric apparatus comprising:
- a partitioned chamber that is formed by separating an inside of a main unit case with a partition;
- and
- a blower that is located in the partitioned chamber,
- wherein the blower comprises:
- a fan;
- an inlet communicating with the partitioned chamber, through which outside air is drawn and sent by the fan;
- and
- an outlet communicating with the partitioned chamber, through which an air flow sent from the fan is exhausted,
- wherein the inlet and the outlet have slits with a specific width or an array of through holes with a specific diameter, and
- the following relationship is satisfied:
- A<C,A<B
- where A represents the width of the slits or the diameter of the through holes of the inlet, B represents a particle size of dust that is allowed to pass through in view of dust-proof performance of the fan, and C represents the width of the slits or the diameter of the through holes of the outlet, and
- wherein the inlet includes a dust collecting element that collects dust.
