Problems solved by technology

[0012] First, there is the inconvenience that the user needs to arbitrarily change the position of the main body in order to adjust the direction of the wind blown from the fan blade in the vertical direction.
That is, there is a problem that the user needs to manually adjust the up and down direction
[0013] Second, even if the user manually adjusts the up and down directions, there is still the problem of only sending air to one side
That is, although the existing air blower can automatically reciprocate in the left and right directions, it cannot reciprocate in the up and down direction, so there is inconvenience that the user needs to adjust the direction arbitrarily.
[0014] Third, the first safety cover and the second safety cover that are usually used to configure the fan blade are formed in a grid shape, so there is a problem that fine dust or foreign matter in the external air will accumulate on the fan blade as it is used
Therefore, there is a problem that the user feels uncomfortable due to dust when using the air blower.

Abstract

The present invention relates to blowers. A blower according to an embodiment of the present invention includes: an upper fan used to generate a first airflow sucked in and discharged through an upper suction part; the second airflow; the airflow changing device is configured between the upper fan and the lower fan, and is used to generate a third airflow in which the first airflow and the second airflow merge; and the control unit controls the The rotational speeds of the upper fan and the lower fan are used to adjust the discharge direction of the third airflow.

Description

technical field [0001] The present invention relates to blowers. Background technique [0002] Generally, a blower is understood as a device for sucking in air and blowing it to the desired location of the user. Such air blowers are mainly arranged in indoor spaces such as residences or offices, and most of them are activated in hot weather like summer to blow air to users, making users feel cool. [0003] Existing air blowers usually consist of a support rod and a blowing part. The existing literature on such prior blowers is as follows. [0004] prior art literature [0005] patent documents [0006] Publication Patent Publication No. 10-2008-0087365 (Date of Publication: October 1, 2008, Name of Invention: Fan) [0007] The structure of the existing air blower mentioned in the published prior art documents includes: a body with a built-in motor; a fan blade part, which is arranged on the body and combined with the motor, and can rotate with the operation of the motor...
