Description

Air controller

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air controller, and more particularly, to an apparatus capable of generating a flow of air by a rotating body and controlling the temperature of the air.

Tesla turbine is a bladeless turbine that consists of a set of disks. The Tesla turbine is characterized in that when the disks rotate, the air inside the Tesla turbine moves to the edges of the disks. When the disk is rotated, air is sucked into the center of the disk, and according to the boundary layer effect, the air moves to the outside of the disk while drawing a spiral trajectory on the surface of the disk.

The boundary layer effect is that when a solid moves, the interface of the fluid adjacent to the surface of the solid also moves along the surface. When the solid and fluid are in contact with each other, there is an interface between the solid and the fluid at a portion of the solid surface. In this case, when the solid moves, the boundary surface also moves along the movement of the solid, wherein the force acting on the interface is not friction but adhesion. On the contrary, when the fluid moves on the surface of the solid material, the solid material is also moved by the adhesive force.

Generally, in a conventional hot air heater, a blade for moving air and a heating element for heating air are separated from each other. For example, the operation structure of the hair dryer is as follows. When air is introduced, a flow of air is formed by a rotating means such as a blade, and the air is heated by a separate heating unit. The heated air is discharged out of the hair dryer through the discharge port. A conventional general warmer may have a large volume of the warmer since the rotating means for providing the flow of air and the heating means for heating the air are separated from each other. In addition, there is a problem that a large noise is generated by the friction between the rotating blade and the air.

In the present invention, to solve the above problems by providing a low noise air controller using the technology used in Tesla turbine.

An air controller according to an aspect of the present invention includes a housing having an inlet port through which air is introduced and a discharge port through which the drawn air is discharged, and laminated at a predetermined interval within the housing, and having a heat exchange part formed thereon. At least one disk, and drive means (rotary drive means) for rotating the disk.

In this case, the heat exchanger may be a heating element or a cooling body.

In this case, the inlet may be disposed in the extending direction of the rotation axis of the disk, the discharge port may be disposed in the extending direction of the tangent to the circumference of the disk.

In this case, an air hole through which air can be distributed may be formed in the center portion of the disc.

At this time, the rotating shaft for rotating the disk may be fixedly coupled to the central portion of the disk.

In this case, the driving means may include a plurality of stator coils and a plurality of permanent magnets (rotor) disposed to be electromagnetically coupled to each other. Each of the permanent magnets may be fixedly coupled to the rotary shaft by predetermined connection means, and the stator coils may be fixedly coupled to the housing, respectively.

In this case, two slip rings are fixedly coupled to the rotating shaft, and each of the slip rings may be configured to receive electricity through a brush.

In this case, the heat exchanger includes a heating element that generates heat when electricity is supplied, and the conductive shaft has two conductive terminals for providing electricity to the heating element, and each conductive terminal is fixed to both terminals of the heating element. May be combined.

In this case, each of the slip rings may include a slip electrode fixedly coupled to the rotating shaft, and each slip electrode may be electrically connected to the two conductive terminals.

In this case, the brush may be configured to supply electricity to the slip ring by sliding contact with the surface of the slip ring when the slip ring rotates.

According to the invention, the disk, to which the heating means are coupled to its surface, can create a flow of air and simultaneously heat the air. Therefore, the air controller does not need a separate means for heating the air can be reduced the overall volume of the air controller. In addition, since the adhesive force between the disk and the air is used, the noise caused by the air flow is reduced.

Hereinafter, with reference to the accompanying drawings an embodiment of the present invention will be described. However, the present invention is not limited to the embodiments described herein and may be implemented in various other forms. The terminology used herein is for the purpose of understanding the embodiments and is not intended to limit the scope of the invention. Also, the singular forms used below include the plural forms unless the phrases clearly indicate the opposite meanings.

The present invention relates to an air controller capable of generating a flow of air by rotation of a disk and adjusting the temperature of the air by using a heat exchanger provided on the surface of the disk. In the following, the idea of the present invention will be described with reference to the air blower in particular among the air controllers, but the idea of the present invention is not limited to the heat blower.

The overall shape of the warm air fan 1 may be, for example, a whistle, and the center of the warm air fan 1 may be a hole having a hole such as a roll of tissue.

The hot air heater 1 includes a rotating part including one or more disks 20 and a rotating shaft 30, a housing 10, an inlet 11 for sucking air, and an outlet 12 for discharging air inside the housing. It may include. The housing 10 is a case forming an outer surface of the warm air fan 1, and may also serve to protect internal components of the warm air fan 1. The housing 10 may include an inlet 11 for introducing air into the housing 10 and a discharge port 12 through which air is discharged from the housing 10. An outer box surrounding the housing 10 may be further provided outside the housing 10. For example, when the hot air fan 1 is used for a hair dryer, a separate enclosure may be provided on the outside of the hot air fan 1 so that the user can easily pick it up by hand.

In FIG. 1, the outer edge of the disk 20 is indicated by a dotted line. The large surfaces of the disks 20 may ideally be all on one plane. In addition, a resistive heating element for providing a heat exchange part may be disposed on the surface of the disk 20.

At the center of the disk 20, the rotation shaft 30, which is the center of rotation of the disk 20, may be fixed and coupled to the disk 20.

FIG. 2 is an internal cross-sectional view of the warm air fan 1 showing a state cut along X-X 'of FIG. 1, and FIG. 3 shows a front view of the warm air fan 1 from another viewpoint.

The warm air fan 1 may be provided with driving means, for example, a motor, for rotating the disk 20. A portion 'A' of FIG. 2 is a portion shown to explain the driving means for rotating the disk 20. When the driving means is a rotary motor, it may be configured to include a rotating shaft 30, a bearing 31, a permanent magnet 32, and a stator coil 33.

The rotating shaft 30 may be coupled to a bearing 31 for rotatably supporting the rotating shaft 30 with respect to the housing 10. An inlet 11 may be formed at an outer side of the bearing 31 to allow air to enter therein.

The permanent magnet 32 may be fixedly coupled to the rotating shaft 30 by a connecting means (eg, a rod) 34. The permanent magnet 32 may rotate about the rotation shaft (30). The stator coil 33 may be provided on an extended surface of the rotation surface of the permanent magnet 32. The stator coil 33 may be attached to the wall of the housing 10. The permanent magnet 32 and the stator coil 33 may serve as one rotary motor. Therefore, when a current flows through the stator coil 33 through the circuit board 40, the permanent magnet 32 rotates, and the rotating shaft 30 fixed to and connected to the permanent magnet 32 rotates, thereby rotating on the rotating shaft 30. The fixedly connected disk 20 can be rotated.

In this case, electricity may be supplied to the circuit board 40 by the power supply 200. The circuit board 40 may be provided with a control circuit 46 for controlling the operation of the driving means.

According to an embodiment of the present invention, the operation principle of the motor provided as the driving means may follow the operation principle of the DC motor, AC motor or BLDC motor. The present invention is not limited by the specific example of the drive means.

Part 'B' of Figure 2 is a portion showing the electricity supply connecting means for supplying electricity to heat the resistive heating element on the rotating disk 20 surface.

Slip rings 41 and 42 may be fixedly coupled to the rotation shaft 30. In this case, the control circuit part 46 of the circuit board 40 formed in the housing 10 may supply electricity to the slip rings 41 and 42 through the brush 43. In this case, the slip ring 41 may be a (+) terminal, the slip ring 42 may be a (-) terminal, and in another embodiment, the slip ring 41 is a (-) terminal and the slip ring 42 is (+). It may be a terminal. The control circuit unit 46 may be configured using electronic components provided on the PCB substrate 40 fixedly coupled to the housing. The outer surfaces of the slip rings 41 and 42 and the brush 43 may be composed of conductors to conduct electricity between them.

4 is a view showing one disk 20 together with the rotation shaft 30 according to an embodiment of the present invention.

Referring to FIG. 4, two

conductive terminals

51 and 52 may be fixedly provided on a part of the surface of the rotating shaft 30 that is fixedly coupled to the center of the disk 20. In addition, an air hole 25 having a predetermined shape may be formed at a periphery of the rotation shaft 30 coupled to the center of the disk 20 as a passage of air introduced from the inlet 11. At this time, the air hole 25 may be disposed adjacent to the space connecting the inlet port 11 on the left side and the inlet port 11 on the right side closest to each other.

The resistive heating element 21 may be disposed on the wide surface of the disk 20 as shown in FIG. 4. In this case, the

conductive terminals

51 and 52 may be fixedly coupled to both terminals 61 and 62 of the resistive heating element 21. For example,

conductive terminals

51 and 52 may be coupled to both terminals 61 and 62 by soldering. Each disk 20 in which the air holes 25 are formed may be fixedly coupled to the rotation shaft 30 by connecting

bridges

71 and 72. The connecting bridges 71 and 72 may be formed integrally with the disk 20.

In the present invention, the arrangement of the resistive heating element 21 may be made by a method such as attaching, laying, installing or printing the resistive heating element on the disk surface.

The

conductive terminals

51 and 52 may be provided by bonding a thin metal foil to the surface of the rotation shaft 30, for example. As shown in FIG. 4, the conductive terminal 51 and the conductive terminal 52 may be insulated from each other.

In one embodiment, the rotating shaft 30, and the disk 20 may be composed of an insulator. The resistive heating element 21 and the

conductive terminals

51 and 52 provided in the disk body may be a conductor.

Alternatively, in another embodiment, the disk 20 body and the resistive heating element 21 may be a conductor, and an insulating film may be provided between the disk body and the resistive heating element 21.

Since the disk 20, the resistive heating element 21, the rotation shaft 30, and the two

conductive terminals

51 and 52 are fixedly coupled to each other, when the rotation shaft 30 rotates, the disk 20 and the two conductive elements are rotated. The

terminals

51 and 52 become one with the rotation shaft and can rotate at the same angular speed. Therefore, the rotation speed of the disk 20 and the two

conductive terminals

51 and 52 may be the same as the rotation speed of the rotation shaft 30. That is, if the rotating shaft 30 rotates at the angular velocity w1, each of the disks 20 may also rotate at the angular velocity w1 and the two

conductive terminals

51 and 52 may also rotate at the angular velocity w1. The disk 20, the resistive heating element 21, the rotating shaft 30, the

conductive terminals

51 and 52, and the slip rings 41 and 42 are fixed to each other and rotated at the same angular speed so that the assembly thereof is 'rotated'. May be referred to. The concept of the rotating unit may further include a rotor (ex: permanent magnet) included in the drive means (motor).

FIG. 5 is a view illustrating only a portion 'B' of FIG. 2, and FIG. 6 is a diagram for describing a coupling relationship between a rotating shaft, a conductive terminal, and slip rings of FIG. 5.

The two brushes 43 shown in FIG. 5 may serve as mediators for providing the currents provided by the control circuit unit 46 to the

rotating slip rings

41 and 42. One end of the brush 43 in contact with the slip ring may slide along the surface of the slip ring when the slip ring rotates to contact the surface to supply current to the surface. The other end of the brush is electrically connected to the control circuit unit 46 and may be fixedly coupled to the housing.

The main body of the slip rings 41 and 42 may be made of an insulator. The surface of the slip rings 41 and 42 which contacts the brush 43 may be a conductor. The slip rings 41 and 42 may have a bobbin-like shape, and a through hole through which the rotating shaft 30 may pass may be formed in the center of the slip rings 41 and 42.

The conductor formed on the outer surface of the slip ring 41 is electrically connected to the conductive terminal 51 formed on the surface of the rotating shaft 30, and the conductor formed on the outer surface of the slip ring 42 is formed on the surface of the rotating shaft 30. It may be electrically connected to the conductive terminal 52 formed. To this end, for example, a via for connecting the conductor formed on the outer surface of the slip ring to the conductive terminal formed on the surface of the rotating shaft may be formed in the cylindrical body of the slip ring. However, the above electrical connection can be made by various conventional techniques. In the specification of the present invention, the 'conductor' may be referred to as a 'slip electrode'.

The brush 43 may be a separate brush for supplying electricity to the slip rings 41 and 42, as described above, instead of the brush included in the driving means such as the rotary motor.

Hereinafter, an exemplary coupling relationship of the rotating shaft, the conductive terminal, and the slip rings will be described with reference to FIG. 6.

First,

conductive terminals

51 and 52 may be formed on the surface of the rotation shaft 30 as shown in FIG. Then, as shown in (b) of Figure 6 by fitting the completed rotary shaft 30 to the slip ring (41, 42) can be provided with a structure as shown in (c) of FIG. Figure 6 is to help understand the relative coupling between the rotating shaft, the conductive terminal, and the slip ring, the process for making this structure is possible in other ways.

FIG. 7 is a flow chart of air in the warm air fan 1 shown in FIG. 2.

FIG. 7 adds a flow of air to that shown by omitting the reference numeral of FIG. 2 for convenience. Reference numeral 301 denotes a flow path of air before being heated which is introduced through the inlet 11. That is, the dotted line 301 indicates the flow path of air before heat exchange. The solid line at 302 denotes a flow path of air heated by the resistive heating element 21. That is, reference numeral 302 denotes a flow path of air after heat exchange. Like this air flow, air may flow between the respective disks 20. The heat-exchanged air flows toward the outer edges of the disks, and if the housing 10 and the discharge port 12 are provided as shown in FIG. 1, the air thus flowed out can be concentrated through the discharge port 12 and flow out. .

conductive terminals

51 and 52 and the surface heating element 21 which are electrically connected to the slip electrodes of the slip rings 41 and 42. The brush 43 does not rotate at the same angular velocity as the rotation shaft 30, but is adapted to supply electricity to the slip rings 41 and 42 by sliding contact with the surfaces of the slip rings 41 and 42, so that the rotary part assembly 503 ) Can be included.

9 is a view for better understanding of the connection relationship between the parts belonging to the rotary assembly 503 and the connection of the rotary assembly 503 and the housing 10.
