Blower

Abstract

The invention relates to a blower. The blower comprises a base; a housing disposed on the upper side of the base and having an air inlet and an air outlet formed therein; a fan disposed inside the housing; a rotating disk connected to the housing and rotatably disposed on an upper side of the base; a motor for generating power for rotating the rotating disk; and a bearing which is disposed between the rotating disk and the base, is fixed to the rotating disk, and is movably supported by the base. As the bearing disposed on the rotating disk is supported on the base and rotates, the rotation of the blower is stably supported by the base and the bearing.

Description

technical field [0001] The present invention relates to a blower, and more specifically relates to a blower rotation structure. Background technique [0002] Blowers work by creating a flow of air that circulates the air in the interior space or creates an airflow that flows toward the user. When the blower is provided with a filter, the blower can improve indoor air quality by purifying polluted air in the room. [0003] In order to adjust the wind direction of the air discharged from the blower, it is necessary to rotate the main body of the blower, and the blower may be provided with a bearing supporting the rotation of the main body. [0004] However, the conventional air blower has a problem that, when a structure for improving the air blowing performance and filtering performance of the air blower is additionally arranged in the main body, there is no durable bearing capable of supporting the increased load. structure. [0005] In addition, the conventional air blow...

Problems solved by technology

[0004] However, the conventional air blower has a problem that, when a structure for improving the air blowing performance and filtering performance of the air blower is additionally arranged in the main body, there is no durable bearing capable of supporting the increased load. structure

[0005] In addition, the conventional air blower also has a problem that, in order to avoid interference with the rotating disk, the arrangement position of the motor for rotating the main body is limited.

[0006] Korean Patent No. 10-1814574 discloses a bearing structure that supports the rotation of the blower and a motor that is arranged on the base to provide rotational force. However, since the bearing is arranged at the center of the main body, it cannot evenly support the main body scattered radially outward. The problem point of the load

In addition, the inner space of the ring-shaped bearing is wasted, and in order to avoid interference with the bearing and the rotating disk, the motor can only be installed on the base, so there is a problem that the space efficiency is reduced.

In addition, since a sufficient separation distance is not ensured between the non-rotating structure and the rotating structure in the fan, there is a possibility that the life of the bearing and the main body will be shortened due to the friction generated between the structures due to the rotation. question

[0007] Korean Patent No. 10-1370267 discloses a bearing structure that supports a shaft to rotate smoothly inside a sleeve, but only supports the rotation of the shaft and does not describe a structure that supports the entire load of the main body
