The disclosure relates to a blowing device capable of adjusting a wind direction of air discharged through a discharge portion and an operating method of the blowing device.
Blowing devices may be used as means to forcibly form a flow of air for circulation in an indoor space or to transmit coolness to users by forming a strong airflow around users. Blowing devices have been improved to send air a long distance by forming a strong airflow, or to provide coolness by transmitting the strong airflow to users, or have been improved to provide comfort to users by providing natural airflow, such as natural wind, around users.
Blowing devices of the related art suggest a structure in which air made to flow by a fan may be directly transmitted to users. In the case of such a structure, there is a characteristic that the discharged air may be transmitted a long distance, but there is a problem that an overly strong airflow may be transmitted to users, which may cause the users to experience some discomfort.
In addition, in blowing devices of the related art, the entire structure including a discharge portion moves and controls a wind direction, which causes problems in that vibration of the structure with the discharge portion and excessive power consumption to rotate the structure with the discharge portion may occur.

The base portion 10 is a housing member having an accommodation space therein. As an example, the base portion 10 may have a cylindrical shape extending in a first direction (Z direction), and may include an opening at an upper end thereof.
The air inflow portion 20 is an air inflow passage through which air is introduced from the outside, such as an exterior of the blowing device 1. According to an example, the air inflow portion 20 fluidly communicates with an inside and with an outside of the base portion 10. As an example, one or more air inflow portions 20 may be disposed on one side of the base portion 10. For example, when the base portion 10 has a cylindrical shape, the air inflow portion 20 may be disposed on an outer circumference of the cylindrical shape.
For example, when a plurality of air inflow portions 20 are provided, the plurality of air inflow portions 20 may be sequentially disposed along the outer circumference of the cylindrical shape. For example, the plurality of air inflow portions 20 may be evenly disposed in a circumferential direction along an outer circumferential surface of the base portion 10 such that air may be sucked in from any direction with respect to the base portion 10. As shown in
The blowing body 30 may be connected to an upper end of the base portion 10 in fluid communication to form a flow path. As an example, the blowing body 30 may extend in the first direction (Z direction) and may be provided in the shape of a conduit with a blocked upper end. For example, the blowing body 30 may be formed in a cylindrical shape extending in the first direction (Z direction).
According to an example, when the blowing body 30 is provided in the cylindrical shape extending in the first direction (Z direction), a lower end 31 of the blowing body 30 may be provided in the shape of an opening. Accordingly, the blowing body 30 may form the flow path through fluid communication with the base portion 10 which will be described below. An upper end 32 of the blowing body 30 may be implemented as a blocking wall extending along one plane to block the flow path formed from the lower end 31. A side portion 33 of the blowing body 30 may be provided in the shape of a conduit extending in the first direction (Z direction). In this case, the side portion 33 of the blowing body 30 may be formed in a cylindrical shape. For example, as shown in
According to an example, the blowing body 30 may be disposed on an upper side of the base portion 10. As described above, the lower end 31 of the blowing body 30 may be provided in the shape of the opening, and the lower end 31 of the blowing body 30 may be disposed to be in fluid communication with the upper end of the base portion 10. Accordingly, the blowing body 30 may be disposed on an upper portion of the blowing portion 40 accommodated in the base portion 10. As the blowing body 30 is disposed on the upper portion of the blowing portion 40, the flow path may be formed inside the blowing body 30 in which air transferred from the blowing portion 40 passes through the lower end 31 of the blowing body 30 and moves in the first direction (Z direction).
The blowing portion 40 may move the air introduced from the air inflow portion 20 to the blowing body 30. According to an example, the blowing portion 40 may be disposed to be accommodated in the base portion 10. The blowing portion 40 may be disposed on an upper portion of the air inflow portion 20 in the first direction (Z direction). Accordingly, a flow path of air leading to the air inflow portion 20, the blowing portion 40, and the blowing body 30 may be formed.
As an example, one or more of a dust collection portion 110 or a photocatalyst portion 120 may be disposed between the air inflow portion 20 and the blowing portion 40. For example, the dust collection portion 110 can be a purification device capable of removing contaminants by adsorbing contaminants included in outside air to the dust collection portion 110. As an example, the dust collection portion 110 may adsorb contaminants using a dust collection filter. However, the disclosure is not limited thereto, and other types of dust collection portions removing contaminants may be used. The photocatalyst portion 120 may include a photocatalyst filter including titanium oxide, silver, etc. The photocatalyst filter may be used to produce a sterilization effect on outside air. However, the disclosure is not limited thereto, and other types of photocatalyst portions removing contaminants may be used. The dust collection portion 110 and the photocatalyst portion 120 are described as examples in the above-described embodiment, but any purification device capable of purifying outside air may be disposed between the air inflow portion 20 and the blowing portion 40.
According to an example, when one or more of the dust collection portion 110 or the photocatalyst portion 120 is disposed between the air inflow portion 20 and the blowing portion 40, purified air from which contaminants have been removed from the outside air may pass through the blowing portion 40 and be supplied to the blowing body 30.
The blowing portion 40 according to an example may include a first blowing fan 41, a second blowing fan 42, a blowing fan support portion 43, a first fan housing 44, and a second fan housing 45. As an example, the first blowing fan 41 and the second blowing fan 42 may be disposed in the up and down direction in the first direction (Z direction), and the blowing fan support portion 43 may be disposed between the first blowing fan 41 and the second blowing fan 42. The first driving motor 50 applying a driving force to the blowing portion 40 may be seated in the center of the blowing fan support portion 43. The first fan housing 44 and the second fan housing 45 may be disposed to surround the first blowing fan 41 and the second blowing fan 42.
The first blowing fan 41 and the second blowing fan 42 may each include a plurality of blades rotatable around a central axis extending in the first direction (Z direction). The central axes of the first blowing fan 41 and the second blowing fan 42 may be coupled to a rotation shaft of the first driving motor 50 supported by the blowing fan support portion 43 and receive rotational force.
The first fan housing 44 may include a circular discharge hole 440 provided in a hemispherical shape and disposed thereon. The second fan housing 45 may include a circular suction hole 450 provided in a hemispherical shape to be coupled to the first fan housing 44 and disposed therebelow. The first fan housing 44 and the second fan housing 45 may be coupled to each other to form a housing space in which the first blowing fan 41 and the second blowing fan 42 are accommodated. The air passing through the air inflow portion 20 may flow into the suction hole 450 in the first direction (Z direction), be transferred through the second blowing fan 42 and the first blowing fan 41, and then be discharged to an upper portion, for example, the blowing body 30, in the first direction (Z direction) through the discharge hole 440.
As shown in
In an exemplary case in which the first inner region 310 and the second inner region 320 are asymmetrical, the separation wall 60 can be disposed at an offset position relative to a central axis of the flowing body 30. In these or other cases, one of the first inner region 310 and the second inner region 320 will have a larger volume than the other.
As an example, as the separation wall 60 is disposed inside the blowing body 30, air introduced into the blowing body 30 through the blowing portion 40 may be distributed with respect to the separation wall 60. For example, the flow path of air flowing into the blowing body 30 through the blowing portion 40 may be divided into a first flow path L1 flowing into the first inner region 310 and a second flow path L2 flowing into the second inner region 320.
According to an example, when the first inner region 310 and the second inner region 320 are symmetrically disposed by the separation wall 60, a flow rate of the first flow path L1 flowing into the first inner region 310 may be substantially the same as a flow rate of the second flow path L2 flowing into the second inner region 320. On the other hand, when the first inner region 310 and the second inner region 320 are asymmetrically disposed by the separation wall 60, the flow rate of the first flow path L1 flowing into the first inner region 310 may be different from the flow rate of the second flow path L2 flowing into the second inner region 320.
The first discharge portion 70 is a discharge portion disposed in the blowing body 30 to discharge air accommodated in the first inner region 310 of the blowing body 30 to the outside. As an example, the first discharge portion 70 may be disposed on a side portion 33 of the blowing body 30. For example, the first discharge portion 70 may be provided in the shape of a slit extending in the first direction (Z direction). Accordingly, air along the first flow path L1 in the first inner region 310 may be discharged to the outside through the first discharge portion 70.

Referring to
The second discharge portion 80 according to an example may include a 2-1 outer wall portion 81 and a 2-2 outer wall portion 82 spaced apart from each other in the thickness direction of the side portion 33 of the blowing body 30, and a second release portion 83 formed in space between the 2-1 outer wall portion 81 and the 2-2 outer wall portion 82. According to an example, the 2-1 outer wall 81 may be formed to extend along the outer circumferential surface of the side portion 33 of the blowing body 30. One end of the 2-1 outer wall portion 81 may have a tapered shape whose width narrows toward the second release portion 83. According to an example, the 2-2 outer wall portion 82 may be formed to extend along the outer circumferential surface of the side portion 33 of the blowing body 30. The 2-2 outer wall portion 82 may be provided in a curved shape. The 2-1 outer wall portion 81 and the 2-2 outer wall portion 82 may be disposed to overlap along the outer circumferential surface of the side portion 33 of the blowing body 30. As an example, the second release portion 83 may be formed in a region where the 2-1 outer wall portion 81 and the 2-2 outer wall portion 82 overlap. For example, the second release portion 83 may be formed in a region spaced in the thickness direction of the side portion 33 of the blowing body 30, in the region where the 2-1 outer wall portion 81 and the 2-2 outer wall portion 82 overlap. As an example, when the blowing body 30 has a circular cross-section, the second release portion 83 may be formed in the diameter direction of the circular cross-section of the blowing body 30.
As described above, air along the first flow path L1 in the first inner region 310 may be discharged to the outside through the first discharge portion 70, and air along the second flow path L2 in the second inner region 320 may be discharged to the outside through the second discharge portion 80. Accordingly, the first discharge portion 70 may be disposed in the first inner region 310 of the blowing body 30, and the second discharge portion 80 may be disposed in the second inner region 320 of the blowing body 30.
According to an example, when the first inner region 310 and the second inner region 320 are disposed to be symmetrical to each other with respect to the separation wall 60, the first discharge portion 70 and the second discharge portion 80 may also be disposed to be symmetrical to each other with respect to the separation wall 60. As an example, the first discharge portion 70 may be disposed at 90 degrees or more and less than 180 degrees counterclockwise along the outer circumferential surface of the side portion 33 of the blowing body from one side 61 of the separation wall 60 (i.e., between 90 and 180 degrees). The second discharge portion 80 may be disposed at 90 degrees or more and less than 180 degrees clockwise along the outer circumferential surface of the side portion 33 of the blowing body from one side 61 of the separation wall 60 (i.e., between 90 and 180 degree). However, the disclosure is not limited thereto, and the first discharge portion 70 and the second discharge portion 80 may be disposed at any positions where the air along the first flow path L1 and the air along the second flow path L2 respectively accommodated in the first inner region 310 and the second inner region 320 may be discharged to the outside.
In an exemplary case in which the first inner region 310 and the second inner region 320 are asymmetrical and one of the first inner region 310 and the second inner region 320 will have a larger volume than the other, the first discharge portion 70 and the second discharge portion 80 may be disposed at positions that correspond to the differences in volume of the first inner region 310 and the second inner region 320.
According to an example, the air along the first flow path L1 discharged through the first release portion 73 may move along the 1-2 outer wall portion 72. As an example, because the 1-2 outer wall portion 72 may have the curved shape, the air along the first flow path L1 discharged through the first release portion 73 by the Coanda effect may move along the outer circumferential surface of the side portion 33 of the blowing body. For example, the air along the first flow path L1 discharged through the first release portion 73 may rotate clockwise along the outer circumferential surface of the side portion 33 of the blowing body.
In addition, the air along the second flow path L2 discharged through the second release portion 83 may move along the 2-2 outer wall portion 82. As an example, because the 2-2 outer wall portion 82 may have the curved shape, the air along the second flow path L2 discharged through the second release portion 83 by the Coanda effect may move along the outer circumferential surface of the side portion 33 of the blowing body. For example, the air along the second flow path L2 discharged through the second release portion 83 may rotate counterclockwise along the outer circumferential surface of the side portion 33 of the blowing body.
When the air along the first flow path L1 rotates clockwise along the outer circumferential surface of the side portion 33 of the blowing body and the air along the second flow path L2 rotates counterclockwise along the outer circumferential surface of the side portion 33 of the blowing body, the air along the first flow path L1 and the air along the second flow path L2 may be mixed at a certain position on the side portion 33 of the blowing body to form an airflow S of the mixed air. As an example, the airflow S of the mixed air may be formed in a straight line in the thickness direction of the side portion 33 of the blowing body, for example, when the side portion 33 of the blowing body has a circular cross-section, in the diameter direction of the circular cross-section.
According to an example, the airflow S of the mixed air may be formed by a combination of the air along the first flow path L1 and the air along the second flow path L2. Accordingly, a direction of the airflow S of the mixed air may be determined by the balance of forces of the air along the first flow path L1 and the air along the second flow path L2. For example, when the forces of the air along the first flow path L1 and the air along the second flow path L2 are the same, as shown in
However, as described above, the separation wall 60 may be disposed to be fixed inside the blowing body 30. Therefore, when the separation wall 60 is disposed to be fixed inside the blowing body 30, the first inner region 310 and the second inner region 320 are also separated to be fixed. Accordingly, the flow rate of air introduced into the blowing body 30 through the blowing portion 40 may be separated at a predefined ratio according to the position of the separation wall 60. That is, the flow rate of the first flow path L1 and the flow rate of the second flow path L2 may be fixed. According to an example of the disclosure, in order to adjust the flow rate of the first flow path L1 and the flow rate of the second flow path L2, the flow rate distribution portion 90 may be disposed.
In accordance with additional embodiments, the separation wall 60 may not be fixed and may be provided to be adjustable. In the or other cases, the blowing body 30 may be provided with an electro-mechanical arrangement that is configured to move the separation wall 60 in one or more directions (i.e., horizontally) to adjust the relative volumes of the first inner region 310 and the second inner region 320. The controller 100 can be configured to control a displacement of the separation wall 60.
The flow rate distribution portion 90 may distribute air moving from the blowing portion 40 to the first inner region 310 and the second inner region 320. The flow rate distribution portion 90 according to an example may be disposed between the blowing portion 40 and the separation wall 60 to distribute the air moving from the blowing portion 40 to the first inner region 310 and the second inner region 320.
The flow rate distribution portion 90 according to an example may include a flat plate member extending along a plane. For example, the flow rate distribution portion 90 may be provided in a semicircular plate shape extending along one plane. As an example, the flow rate distribution portion 90 may be disposed at a lower end of the separation wall 60 to be rotatable around a central axis C. For example, the flow rate distribution portion 90 may rotate by 60 degrees or less clockwise and by 60 degrees or less counterclockwise around the central axis C. However, the disclosure is not limited thereto, and a rotation angle of the flow rate distribution portion 90 may be determined differently according to a flow rate distribution ratio of the air along the first flow path L1 and the air along the second flow path L2.
As the flow rate distribution portion 90 rotates around the central axis C, the air moving from the blowing portion 40 may be guided to the first inner region 310 and the second inner region 320. The flow rate of the first flow path L1 moving to the first inner region 310 and the flow rate of the second flow path L2 moving to the second inner region 320 may be adjusted according to the rotation angle of the flow rate distribution portion 90. According to an example, the central axis C of the flow rate distribution portion 90 may be coupled to a rotation shaft of the second driving motor 95 that applies power to the central axis C and receive rotational force. The controller 100 may control the second driving motor 95 to adjust the rotation angle of the flow rate distribution portion 90. Hereinafter, a method of adjusting the direction of the airflow S of the mixed air by adjusting the rotation angle of the flow rate distribution portion 90 using the controller 100 is described in more detail.
Referring to
Next, the air introduced into the air inflow portion 20 may be transmitted to the blowing body 30. (S120) The air introduced into the air inflow portion 20 by the first driving motor 50 may move in the first direction (Z direction) by passing through the blowing portion 40. The air moved in the first direction (Z direction) may be transmitted to the blowing body 30. Accordingly, a flow path of air leading to the air inflow portion 20, the blowing portion 40, and the blowing body 30 may be formed.
According to an example, fine dust may be collected from the air introduced into the air inflow portion 20, and purified air from which contaminants have been removed may be transferred to the blowing portion 40. For example, one or more of the dust collection portion 110 or the photocatalyst portion 120 may be disposed between the air inflow portion 20 and the blowing portion 40. The dust collection portion 110 or the photocatalyst portion 120 may collect fine dust from the air introduced into the air inflow portion 20 and remove contaminants. The air purified by the dust collection portion 110 or the photocatalyst portion 120 may be transferred to the blowing portion 40. However, the disclosure is not limited thereto, and the flow path of air leading to the air inflow portion 20, the blowing portion 40, and the blowing body 30 may be formed without the dust collection portion 110 or the photocatalyst portion 120.
Next, an angle at which the flow rate distribution portion 90 rotates around the central axis C may be adjusted. (S130) As an example, when the user applies an input signal to adjust a direction of the airflow S of mixed air discharged from the blowing device 1, the controller 100 may operate the second driving motor 95. The flow rate distribution portion 90 may rotate at a certain angle clockwise or a counterclockwise direction around the central axis C, by the operation of the second driving motor 95. For example, the flow rate distribution portion 90 may rotate by 60 degrees or less clockwise and by 60 degrees or less counterclockwise around the central axis C.
According to an example, as shown in
Next, a flow rate of air transmitted to each of the first inner region 310 and the second inner region 320 may be distributed using the flow rate distribution portion 90. (S140) For example, the flow rate of air transmitted to each of the first inner region 310 and the second inner region 320 of the blowing body 30 may be adjusted according to the rotation angle of the flow rate distribution portion 90. For example, as shown in
Next, the air in the first flow path L1 may be discharged using the first discharge portion 70, and the air in the second flow path L2 may be discharged using the second discharge portion 80. (S150) For example, the air in the first flow path L1 flowing into the first inner region 310 may be discharged through the first discharge portion 70. In addition, the air in the second flow path L2 introduced into the second inner region 320 may be discharged through the second discharge portion 80.
Next, the air in the first flow path L1 and the air in the second flow path L2 may each move along an outer circumferential surface of the blowing body 30. (S160) For example, the air in the first flow path L1 discharged through the first discharge portion 70 may move along the outer circumferential surface of the blowing body 30. For example, the air of the first flow path L1 discharged through the first release portion 73 included in the first discharge portion 70 may move along the 1-2 outer wall portion 72 provided in a curved shape by the Coanda effect.
In addition, the air of the second flow path L2 discharged through the second discharge portion 80 may move along the outer circumferential surface of the blowing body 30. For example, the air of the second flow path L2 discharged through the second release portion 83 included in the second discharge portion 80 may move along the 2-2 outer wall portion 82 provided in a curved shape by the Coanda effect.
Next, the air of the first flow path L1 and the air of the second flow path L2 may be mixed to form the airflow S of the mixed air moving in a certain direction. (S170) As an example, the air of the first flow path L1 moving along the outer circumferential surface of the blowing body 30 and the air of the second flow path L2 may be mixed to form the airflow S of the mixed air moving in the certain direction. For example, as shown in
On the other hand, as shown in
In addition, as shown in
As described above, the flow rate of the first flow path L1 and the flow rate of the second flow path L2 may be adjusted according to the angle at which the flow rate distribution portion 90 rotates around the central axis C. A discharge direction of the airflow S of the mixed air may be determined based on a difference between the flow rate of the first flow path L1 and the flow rate of the second flow path L2.
