Thing about blower

Conventional fans cannot blow air in multiple directions at the same time.
In addition, the direction of ventilation is also restricted for air conditioning equipment.

JP 2016-153653

Many conventional fans have the function of swinging, allowing multiple people around them to be exposed to the wind, but each subject is not continuously exposed to the wind, and intermittently. You can only receive the wind when you turn to the person. Therefore, even if a blower with a large air volume is used, it is difficult for each subject to cool down satisfactorily.
However, it is annoying and unreasonable to install multiple fans in the same room so that each person can cool down.
In the case of a ceiling cassette type indoor unit of a package type air conditioner, it is possible to blow air in multiple directions at the same time, but since the direction in which each air outlet is directed is limited, the direction of ventilation is also limited. It is impossible to blow air in one direction.
In addition, a structure that can blow air over a wide angle is also shown, but since it is also blown in unnecessary directions, it is wasteful and it is difficult to blow air to each subject at a sufficient wind speed and volume. ..

The blower is equipped with a plurality of blowout shells that are equipped with outlets and are rotatably fitted to the main body with respect to a substantially vertical and identical rotation axis (the straight line that is the center of the rotational movement of an object is called the "rotation axis"). One or more impellers and outlets driven by a motor to form a space surrounded by air-blocking parts such as the outlet shell, other outlets, intake ports, and other housing parts. By including a wind path (a space that serves as an air flow path is called a "wind path") that connects the impeller and the external space via the air intake and the air intake, multiple arbitrary horizontal blowouts can be made at the same time. It is possible to configure a blower device that enables it. Further, the rotating shaft of the impeller and the rotating core of the motor are substantially the same by directly connecting the impeller and the rotating core of the motor (the rotating shaft is referred to as a "rotating core"). The structure can be made simpler and more rational by making it substantially vertical and making it substantially the same as the rotation axis of the blowout shell with respect to the device.
Further, if the air outlet is provided with a wind direction adjusting blade in the vertical direction, which is pivotally supported by the horizontal rotation axis, it is possible to blow air in any direction, not limited to the horizontal direction.

Hereinafter, common matters and the like regarding the entire disclosure according to the present application will be described, and then examples will be shown.
The matters described in the "mode for carrying out the invention" do not limit the matters described in the claims.

By connecting the rotating core of the motor to the impeller via a gear or the like, the rotating shaft of the rotating core of the motor and the rotating shaft of the impeller can be separated. It is better to connect the rotating core and the impeller directly and arrange them coaxially. Further, by making these rotation axes vertical and matching the rotation axis with respect to the housing of the blowout shell, the gap between the impeller and the hollow portion edge of the upper and lower surfaces of each blowout shell through which the impeller penetrates is minimized. Moreover, it can be suppressed to a constant level, and the movement of pressurized air between the blowout shells and mutual adverse effects can be suppressed, which is better.
In this way, the rotating core of the motor, the impeller, and each blowout shell can have a minimal rational structure by sharing the vertical axis of rotation.

If the air outlet is provided with a blade that is pivotally supported by a horizontal rotation axis and can adjust the wind direction in the vertical direction, it is possible to blow air in any direction in three dimensions, which is better.

When an air filter is provided, it is better to install it on the intake port side where the flow velocity of the air flow is small.

When a tower-type blower is configured according to the disclosure, when the tower type blower is operated with a large air volume, a tipping moment is generated in the housing due to the reaction force of the blown air. Therefore, depending on the conditions, it is necessary to prevent the vehicle from tipping over, but it is conceivable to provide a base stand or increase the width of the housing. In addition, in order to prevent falls due to an earthquake and reduce damage during falls, it is effective to place heavy parts such as motors at the bottom as much as possible to lower the center of gravity.

Generally, since the target person who is exposed to the wind operates the electric fan or the like by himself / herself, the arrangement of the switches and the default blowing direction are the front and the front of the main body. Therefore, the blower according to the disclosure may also be provided with an outlet such as a front facing the base unit or the like that does not rotate, in addition to the outlet shell.

By using the internal shape of each blowout shell as a scroll casing and penetrating them through a centrifugal fan, it is possible to form a blower device that can obtain a large air volume while having a simple structure.
Here, an example of a structure in which a turbo fan, which is a centrifugal fan, is used for the impeller 101, and an intake port 102 is provided on the central portion of the top surface of the device and the side surface of the base unit 104 to intake air is shown.
The blowout shell 103 has a substantially prismatic outer shape, and is composed of a side wall having a scroll-shaped horizontal cross section and an upper and lower bottom surfaces having a blowout port 106.
The impeller 101 is installed so as to penetrate the inside of the blowout shell 103 which is continuously fitted and arranged in the vertical direction.
Of the upper and lower bottom surfaces of the blowout shell 103 having a substantially prismatic outer shape, the bottom surface through which the impeller 101 penetrates forms a hollow blocking diaphragm 111 which is a planar body having a circular through opening 109.
When the impeller 101 is rotated by the motor 105, the hollow space inside the impeller 101 becomes a negative pressure, and the impeller 101 takes in air from the outside of the device through the intake ports 102 above and below the device, and also causes the scroll casing. The space formed by the air outlet shell 103 and the inner surface of the side wall is pressurized to a positive pressure, and each air outlet 106 blows out a jet in a directed direction and blows air.
The adjacent outlet shells 103 are slidably connected to each other by an annular guide, and each outlet shell 103 is rotatably fitted to the same rotation axis as the impeller 101.
The impeller 101 includes an annular rib plate 108 that is close to the hollow blocking diaphragm 111 on the upper and lower bottom surfaces of each blowout shell 103 that penetrates and is orthogonal to the blade of the impeller 101. Further, the clearance between the annular rib plate 108 and the edge of the through opening 109 of the hollow blocking diaphragm 111 is made as small as possible, and the air pressurized by the impeller 101 is adjacent to the outside of the impeller 101. It is better to suppress the distribution between the matching blowout shells 103 and the mutual adverse effects, so that a rational ventilation without waste is possible.
The impeller 101 may use a sirocco fan instead of the turbo fan. Further, when a turbofan is used, the internal shape of the side wall of the blowout shell 103 does not necessarily have to be a scroll shape, and may be a substantially cylindrical shape provided with a blowout outlet.
The blowout shell 103 is arranged with a certain gap between them, the impeller 101 is divided into a size that fits between the upper and lower bottom surfaces in each blowout shell 103, and the divided impeller 101 has spokes. By providing a hub and a hub and connecting them to each other with a rotating core, the hollow space inside the impeller 101 is a gap between the through openings 109 on the upper and lower bottom surfaces of each blowout shell 103 and each blowout shell 103. Since it is directly communicated to the external space through the air, a larger intake amount can be obtained and a larger amount of blown air can be obtained. At this time, if a mesh-shaped frame described later is provided, the structure can be easily constructed, which is better.

In the first embodiment, a centrifugal fan having a length that covers the entire mounting range of the blowout shell 103 is built in, but the entire inside of each blowout shell 103 is communicated, and the impeller is a centrifugal fan that is a shorter turbofan. An example is shown in which the static pressure inside the outlet shell 103 communicated with the fan is pressurized to a positive pressure which is substantially equal pressure, and the ejection flow is blown out from the outlet 106 of each outlet shell 103.
The device has a circular intake port 102 near the center of the top surface, and an impeller 101 is installed in the vicinity of the intake port 102. The impeller 101 has a blocking disk 112 as a bottom surface for blocking airflow, and an annular rib plate 108 as a top surface capable of allowing airflow to pass through through a circular opening, via an impeller rotating core 107. It is connected to the motor 105.
The opening of the annular plate is close to the intake port 102 on the top surface of the device, and the size and the central axis are substantially the same.
When the impeller 101 is rotated, the static pressure in the hollow space inside the impeller 101 becomes a negative pressure, and intake air is taken from the circular opening of the annular rib plate 108 and the intake port 102. The inside of the outlet shell 103 that has been communicated is pressurized to a positive pressure by the impeller 101, and jets are blown out from the outlet 106 of each rotatable outlet shell 103 under substantially uniform conditions to blow air. can.

In the structure of the second embodiment, the opening area of the intake port 102 is limited, and it is difficult to realize a large amount of air. However, the intake port is also on the side surface of the base unit 104 in which the motor 105, the electric circuit, etc. are installed. The area of the entire intake port can be expanded, and a larger amount of air can be blown.
The impeller 101 is a centrifugal fan which is a turbofan having an annular rib plate 108 on the upper and lower surfaces, and is installed in the vicinity of the hollow blocking diaphragm 111 on the upper surface of the base unit 104. The upper part is communicated to the intake port 102 at the top of the housing via the internal air passage 110, and the lower part is communicated to the intake port 102 on the side surface of the base unit 104 via the central opening of the hollow blocking diaphragm 111.
When the impeller 101 rotates, it takes in air from the intake port 102 on the side surface of the base unit 104 and the intake port 102 at the top, and the internal space of each communicating outlet shell 103 outside the impeller 101 is substantially even. Pressurized to a positive pressure, the jets are blown out substantially evenly from the outlet 106 of each outlet shell 103, and the air is blown in the direction in which the outlet 106 is directed.

Most conventional tower fans form a substantially prismatic cross-flow fan consisting of an impeller equipped with a vertical rotating shaft and a runner forming a substantially cylindrical centrifugal fan, and a housing forming a rectifying section. The air taken in from the intake grill on the side surface of the housing passes through the housing and the impeller in the horizontal direction, and is blown out from the air outlet on the side surface of the housing to be blown. In the embodiment, an example of the structure of a device that divides the housing of a blower forming such a conventional cross-flow fan into a plurality of blowout shells 103 in the vertical direction and realizes simultaneous blowing in a plurality of directions is shown.
Similar to the first embodiment, of the upper and lower bottom surfaces of the blowout shell 103 having a substantially prismatic outer shape, the bottom surface through which the impeller 101 penetrates forms a hollow blocking diaphragm 111 which is a planar body having a circular through opening 109. ..
The impeller 101 is provided with a blocking disk 112 as a partition wall and a structural material in the vicinity of the upper and lower bottom surfaces of each blowing shell 103, and a gap between the blocking disk 112 and the edge of the through opening 109 is formed. Make it as small as possible to suppress the flow of air between the insides of the adjacent outlet shells 103.
As a result, the device can blow air in any plurality of substantially horizontal directions depending on the orientation of each blowing shell 103.
In general, the cross-flow fan has a small static pressure and the wind speed of the blown jet is not high, so that it interferes with or cancels the blown jet and the intake airflow of the adjacent jet shells 103, making effective blowing difficult. Will be. Therefore, by providing arcuate grooves and protrusions on the upper and lower bottom surfaces of each outlet shell 103, the relative rotational range of adjacent outlet shells 103 and the projection of the intake port 102 and the outlet 106 onto the horizontal plane are projected. Adjacent blowouts can be made by limiting the angle formed by each other, by enlarging the upper and lower bottom surfaces of the blowout shells 103, or by inserting a horizontal plate whose projection onto the horizontal plane is larger than that of the blowout shells 103. It is better to have a structure for preventing interference between the suction airflow and the blowout airflow of the shell 103.
The impeller 101 is divided into a size that fits between the upper and lower bottom surfaces in each blowout shell 103, and each has spokes and hubs, which are connected to each other by a rotating core, and the upper and lower sides in each blowout shell 103. If the opening on the bottom surface is set to the minimum size that allows only the rotating core to penetrate, air flow inside the adjacent blowout shells 103 can be suppressed, and depending on the conditions, a more rational structure may be used. Can be better.

The entire inside of each blowout shell 103 is communicated, the top of the device is closed in a non-ventilable manner, an intake port 102 is provided on the side surface of the base unit 104, and an impeller 101 which is an axial fan is installed above the intake port 102, and the communication is performed. If the entire inside of the blowout shell 103 is pressurized to a positive pressure, the structure according to the disclosure can be easily realized.

In the fifth embodiment, the structure for sucking air from the side surface of the base unit 104 is shown, but if the impeller 101 is installed close to the top of the device and the air intake port 102 is provided on the top surface of the device, the blowout shell 103 is the same. It is possible to wrap around the entire vertical direction of the device, and it is possible to configure a simple device that is approximately minimized.

Although it is difficult to obtain a large static pressure with the axial flow fan alone, two axial flow fans having blades that mirror each other are arranged coaxially, and one of them is connected to the rotating core of the motor in the forward direction. A larger static pressure can be obtained by constructing a counter-rotating fan in which the other is rotated in the opposite direction via the reversing mechanism.
Here, the rotating core of one impeller is an outer rotating core 113 having a hollow cylindrical shape, and the rotating core of the other impeller is an inner rotating core 114 inserted into the outer rotating core 113, and the inner side is used. The rotating core 114 is directly connected to the rotating core of the motor 105, and is engaged with the outer rotating core 113 via the reversing mechanism 115. The inner rotating core 114 is pivotally supported by a hub portion at the center of the spoke-shaped frame installed at the motor 105 and the intake port 102 on the top surface of the device. The reversing mechanism 115 is held on the upper part of the base unit 104 by a bridge or a bracket take-out, and the outer rotating core 113 is pivotally mounted from the reversing mechanism 115 to the lower part of the hub portion at the center of the spoke-shaped frame. A counter-rotating fan is configured by an impeller 101 joined to the outer rotating core 113 and an impeller 101 joined to the inner rotating core 114, which are close to the upper end and the lower end of the outer rotating core 113, respectively. The blades of these counter-rotating fans are installed in a direction in which the inside of each blowout shell 103 is pressurized to a positive pressure with respect to the rotation direction of each rotation core driven by the motor 105.
As described above, the apparatus includes two sets of counter-rotating fans on the upper and lower sides, and takes in air from the intake ports 102 on the top surface and the side surface of the base unit 104, respectively, to create a space between the two sets of counter-rotating fans. Pressurized to a positive pressure, a jet is blown out from the outlet 106 of each outlet shell 103 set in an arbitrary direction, and the air is blown.
Although the device is a single motor, it can drive two sets of counter-rotating fans, and can realize a large static pressure and a large air volume.

Depending on the configuration of the air passage of the device, it may be optimal to use a mixed flow fan for the impeller, which combines the characteristics of an axial fan and a centrifugal fan.
Here, an example of the structure of a device using a mixed flow fan, in which an intake port is provided only on the top surface of the device, is shown.
An intake port 102 is provided on the top surface of the device, and an impeller 101, which is a mixed flow fan, is installed on the base unit 104. The device includes an internal air passage 110, and when the impeller 101 rotates, the negative pressure generated in the center of the impeller causes air intake from the intake port 102 via the internal air passage 110. At the same time, the impeller 101 pressurizes the space inside each of the outlet shells 103, which is outside the internal air passage 110 and communicates with each other, to a positive pressure, and the outlet 106 of each outlet shell 103 set in an arbitrary direction. Blow out more jets and blow.
In the case of this structure, the impeller 101 may be a turbofan instead of the mixed flow fan.

So far, the structure of the device by the housing or the blowout shell having a substantially cylindrical or substantially prismatic shape has been shown, but here, an example of the structure of the device having a substantially hemispherical shape is shown. Similar to the eighth embodiment, the impeller 101, which is a mixed flow fan, is installed close to the base unit 104, and the air is sucked from the intake port 102 at the top of the housing through the internal air passage 110, and outside the internal air passage 110. Yes, the space inside the housing including the outlet shell 103 is pressurized to a positive pressure, and air is blown from the outlet 106 of each outlet shell 103.
In this embodiment, the blowout shell 103 is an annular member that forms part of a substantially hemispherical outer shape of the device and comprises an outlet 106 with horizontal slits over a range.
In the structure shown in Example 8, the impeller is small with respect to the size of the entire device, and it is difficult to obtain a large air volume. However, in the structure according to the embodiment, the entire device is small, so that the size of the device is large. On the other hand, a relatively large air volume can be obtained. In addition, it can be installed on a table or the like, and it is easy to provide a sufficient air volume to a seated person who surrounds the table and is located within a limited range. Further, since the outer shape of the device is substantially hemispherical, it is easy for the air flowing on the surface of the device to be attracted to the jet jet by the Coanda effect to form a smooth air flow, and it is easy to effectively form a jet jet in the intended direction. ..
The structure may be inverted in the vertical direction and mounted on the ceiling.
In addition, although an example of a structure in which the outer shape is a substantially hemispherical shape is shown here, a floor-standing type supported by a support rod from a base stand or a ceiling-mounted type suspended from the ceiling may be used, and the main body may be a substantially spherical shape. can. In this case, if the structure shown here having a substantially hemispherical outer shape is integrated with the structure inverted in the vertical direction to share the motor, it can be rationally configured. In the case of the ceiling suspension type, it is better to suspend the main body with a plurality of suspension materials in order to prevent the main body from rotating due to the reaction force of the wind pressure at the time of blowing.

The disclosure can be applied to a packaged air conditioner indoor unit, a fan coil unit, an air purifier, etc., in addition to forming a dedicated electric fan or circulator. When applied to air conditioners, it can blow cold and hot air directly to the occupants, like spot air conditioners, without having to reach or maintain the target temperature for the entire room. The sensible temperature can be lowered. As a result, even in a semi-outdoor space or a room with a large ventilation volume, it is possible to provide a sufficient cooling / heating effect with power saving.
Here, an example of the structure applied to the ceiling cassette type package air conditioner indoor unit is shown. The device comprises a portion stored in the ceiling surface and a portion exposed below the ceiling surface. A mechanical unit 117 containing a turbo fan impeller 101, a heat exchange coil 116, etc. was suspended from the upper floor slab in the ceiling surface, and a double cylinder structure was formed under the ceiling surface. The air passage unit 118 including the intake port 102 and the outlet shell 103 is attached so as to project. When the impeller 101 rotates, the hollow central portion becomes negative pressure, and indoor air is introduced from the intake port 102 at the lower end of the internal air passage 110 through the internal air passage 110 installed near the lower end of the impeller 101. do. The impeller 101 pressurizes the introduced air to a positive pressure and blows it to the outer periphery, and this air flows through the heat exchange coil 116 surrounding the outer periphery of the impeller 101 to be cooled or heated, and the wind is cooled or heated. It is sent to the space outside the internal air passage 110 in the way unit 118, and is blown out as a jet from the outlet 106 of each outlet shell 103. The outlet 106 of the outlet shell 103 is provided with a vertical wind direction control blade 119 pivotally supported by a horizontal rotation axis, and the vertical component of the wind direction of the outlet air can be adjusted.
The direction of the air flow in the device is shown as an air flow 127.
Further, the lower part of the heat exchange coil 116 is provided with a dew condensation water receiver. Further, if the air passage unit 118 has a structure in which the mechanical unit 117 is suspended and installed and the ceiling is constructed, the construction and maintenance are facilitated, which is better.
The impeller 101 may be used as a mixed flow fan in combination with the shape of the air passage and the rectifying portion.

In the tenth embodiment, the structure in which the air passage unit 118 is exposed below the ceiling surface is shown, but an example of the structure in which a disk-shaped face unit is provided instead of the air duct unit is shown.
By omitting the protruding air passage unit 118, the intake port 102 is arranged at the center of the face unit 120, which has substantially the same height as the ceiling surface. Similarly, the blowout shell 103 has an annular and band-like shape on the face unit, and is rotatably attached by a slider. The portion of the face unit 120 to which the blowout shell 103 is attached forms a slit that penetrates the top and bottom of the face unit 120. Therefore, the members of the face unit 120 that are divided by the slits are structurally and integrally connected by the cross-linking portion 121.
The mechanical unit 117 has the same structure as that of the tenth embodiment, and the air introduced from the intake port 102 is pressurized by the impeller 101, flows through the heat exchange coil 116, is cooled or heated, and each outlet shell 103 is heated. It is blown out from a slit-shaped outlet 106 having a tool and blown.

The device according to the disclosure may have a structure in which adjacent outlet shells are connected to each other by a guide that is slidably fitted to each other, but when one outlet shell is rotated, the adjacent outlet shells are also rotated. Therefore, the angle adjustment work is inconvenient. Therefore, it is better to install a frame inside and adopt a structure in which the blowout shell is slidably fitted to the frame. As a rational structure of the frame, it is conceivable to have a structure in which the horizontal annular guide 126 for slidably fitting each blowout shell 103 is supported by a linear member or the like from a part of the main body such as the base unit 104. ..
The figure shows an example of a frame structure applied when constructing a blower having a substantially columnar shape as shown in the second embodiment or the like. A mesh composed of a brace 122, a vertical member 123, and a horizontal member 124, which are linear members, is formed in a cylindrical shape to form a frame. The mesh can be easily manufactured by integrally molding a resin or the like. Since these members form a truss in the plane, a large in-plane strength and in-plane rigidity can be exhibited, and at the same time, in the direction of the outlet 106 of the outlet shell 103 fitted and set in any direction. Therefore, it hardly obstructs the airflow blown out from the outlet, and enables uniform and effective airflow. If the vertical member 123 has ribs 125 having a large member cross section at regular intervals, the strength and rigidity of the entire frame can be improved, which is better. Further, when the horizontal annular guide 126 for slidably fitting the blowout shell 103 is provided in the frame as a part of the cross member 124, the strength and rigidity of the frame can be reasonably improved. ,Better. By improving the strength of the frame and the rigidity including the torsional rigidity in this way, it is possible to prevent the frame from being distorted by an external force acting on the frame, such as when the blowout shell 103 is rotated, and the blower device is hindered. Allows use without.
The frame can be applied not only to a device having a substantially prismatic shape, but also to a spherical structure shown in Example 9, a structure of a horizontal face unit of a ceiling cassette type package air conditioner indoor unit shown in Example 11. In the latter case, the frame also has a substantially horizontal disk shape, but here, the vertical member 123 is replaced with a linear member in the radial direction and the horizontal member 124 in the circumferential direction.
