It is a view shown in the direction, and FIG. 8 is a view showing the flow of air through an adjustment member of a cordless hair dryer capable of mounting and angle adjustment according to an embodiment of the present invention, and FIG. 9 is a view showing the flow of air according to another embodiment of the present invention. This is a diagram showing the combination of the nozzle part of a cordless hair dryer that can be mounted and angle adjusted and the second case.

Referring to Figures 1 and 9, a cordless hair dryer 1000 capable of mounting and angle adjustment according to an embodiment of the present invention includes a case part 100, a rotating member 200 and/or a power member 300 and It may include an adjustment member 400 and may further include a nozzle unit 500 and/or a cradle 600.

The wireless hair dryer 1000, which can be mounted and angle adjusted, sucks the air existing outside the case unit 100 into the internal space of the case unit 100 by the power member 300 and then returns it to the case unit 100. It can provide blowing or warm air to the user by discharging it to the outside. For example, a nichrome wire coated with far-infrared rays may be placed inside the case unit 100, and as the nichrome wire is heated, the temperature of the air inside the case unit 100 may increase. According to this, high temperature air can be provided to the user. Meanwhile, raising and maintaining the temperature of the internal air can be selected by the user. For example, a button may be formed on the case portion 100, and the nichrome wire may be heated by the user manipulating the button. When the user operates a button and the nichrome wire is heated, warm air may be provided to the user. Since this technology is a very basic technology for hair dryers, detailed explanation will be omitted.

The case unit 100 may include a first case 110 and a second case 120.

The first case 110 may be implemented as a cylinder with a hollow interior and an opening at one end. For example, the first case 110 may be implemented as a long cylinder and may be made of synthetic resin. The other end of the first case 110 may be cut in a direction perpendicular to the longitudinal direction of the cylinder, and one end of the first case 110 may be cut diagonally in the thickness direction of the cylinder. That is, one end of the first case 110 may be formed to have an inclined surface. An opening may be formed in a portion of the inclined surface of the first case 110. Here, it is preferable that the shape of the opening corresponds to the outer surface of the rotating member 200, which will be described later, so that the outer side of the rotating member 200 can be completely coupled to the opening without space.

The second case 120 may be made of the same synthetic resin as the first case 110 and may be implemented as a cylinder with a hollow interior like the first case 110. However, the second case 120 may have openings formed at both ends. The other end of the second case 120 may be cut in a direction perpendicular to the longitudinal direction of the cylinder, and one end of the second case 120 may be cut diagonally in the thickness direction of the cylinder. That is, one end of the second case 120 may be formed to have an inclined surface. Here, one end of the second case 120 is preferably formed to have the same slope as the one end of the first case 110.

One end of the second case 120 may be rotatably installed in the first case 110. One end of the second case 120 may be installed to face one end of the first case 110 so that each side is parallel. At this time, the opening formed in one end surface of the first case 110 and the opening formed in one end surface of the second case 120 may be positioned to face each other. According to this, the inner space of the first case 110 and the inner space of the second case 120 can be communicated with each other.

One end of the first case 110 and one end of the second case 120 can be connected and rotated by a rotating member 200, which will be described later, and as the second case 120 rotates, the case portion 100 The overall height can be adjusted. According to this, the air discharge height and position can also be adjusted. This will be described later.

The first case 110 and the second case 120 are provided with a plurality of inlet holes (h) that allow external air to flow into the internal space, and a filter may be placed in each inlet hole (h).

For example, a plurality of inlet holes h may be formed on the other end surface of the first case 110 and the outer surface of the first case 110. On the other end surface of the first case 110, a plurality of rectangular inlet holes h1 and a plurality of circular inlet holes h2 may be formed to be spaced apart from each other. Additionally, a plurality of inlet holes h3 having different lengths may be formed on the outer surface of the first case 110 and spaced apart from each other. At this time, the plurality of inlet holes (h3) formed on the outer surface of the first case 110 are near one end of the first case 110, that is, when the user holds the first case 110 and uses the hair dryer. It is preferable to form it in a part that is difficult to grip.

On the outer surface of the second case 120, a plurality of inlet holes (h4) may be installed in opposite directions. The plurality of inlet holes (h4) may be formed to have a length, and the length may become longer toward the other end of the second case 120.

The plurality of inlet holes (h) described above are formed in various places of the case portion 100 and can intake external air from various positions and directions. The plurality of inlet holes (h) can be arranged in various intake positions while reducing the intake area, thereby maintaining the amount of intake air (total intake area) and diversifying the intake direction and position. According to this, the amount of air each inlet hole (h) intakes is small and the individual intake area is also small, which has the effect of reducing friction noise generated by friction of air during intake. In other words, friction noise can be significantly reduced compared to the case where the hole for introducing air is installed in one large location.

A filter may be placed where a plurality of inlet holes (h) are formed. The filter can prevent foreign substances such as dust and hair from entering the case portion 100 through the inlet hole (h). The filter may be made of a heat-resistant material including glass fiber, heat-resistant fiber, and carbon-based fiber, and is disposed on the inner surface of the inner space of the case portion 100, that is, the portion where the plurality of inlet holes (h) are formed, to prevent foreign substances. It is possible to prevent it from entering the internal space of the case portion 100.

The rotating member 200 is fixed to one end of the first case 110 and is connected to one end of the second case 120 to guide the rotation and fixation of the second case 120. In more detail, the rotating member 200 may include a first rotating member 210 and/or a second rotating member 220.

The first rotating member 210 is fixed to the opening at one end of the first case 110 and can control the rotation radius of the second case 120. Referring to FIG. 6, the first rotating member 210 is implemented in an annular shape with a thickness, and a plurality of first wings 211 that can be coupled to and fixed to the first case 110 are formed to protrude on the outer surface. You can. For example, two or more insertion spaces into which the first wing portion 211 of the first rotating member 210 can be inserted may be formed on the inner surface of the first case 110, protruding in the direction of the inner space, and the first The first rotating member 210 can be fixed to the first case 110 by inserting the wings 211 into each insertion space. According to this, the first rotating member 210 can be prevented from rotating in the first case 110 due to external force.

A seating portion on which the second rotating member 220 can be seated may be formed on the inner surface of the first rotating member 210, protruding in the direction of the inner surface of the first rotating member 210. It is preferable that the protruding height of the seating portion is formed lower than the inner surface of the second rotating member 220. As the seating portion is formed to protrude, a space in which the second rotating member 220 can be seated and disposed can be provided in the inner space of the first rotating member 210.

Meanwhile, a concave portion 212 into which the protrusion 221 of the second rotating member 220 can be inserted may be formed by recessing the inner surface of the first rotating member 210. The protrusion 221 of the second rotating member 220, which will be described later, can be selectively inserted into or removed from the concave portion 212.

The second rotating member 220 is disposed in the inner space of the first rotating member 210 and can rotate along the inner surface of the first rotating member 210. For example, the second rotating member 220 may be implemented as a ring shape. At this time, it is preferable that the outer size (diameter) of the second rotating member 220 is smaller than the inner size (diameter) of the first rotating member 210. This is because if the outer size of the second rotating member 220 is larger than or equal to the inner size of the first rotating member 210, it is difficult to rotate the second rotating member 220.

A second wing portion 222 that can be coupled to the second case 120 may be protruding from one end surface of the second rotating member 220. For example, the second wing portion 222 may protrude in the thickness direction from one end surface of the second rotating member 220 and may be bent in the direction of the outer surface of the second rotating member 220. These second wings 222 may be formed on the left and right sides of the second rotating member 220, respectively. The second wing portion 222 may be in contact with one end surface of the first rotating member 210. That is, the lower side of the second wing 222 may be arranged to rest on one end of the first rotating member 210.

In the above-described second rotating member 220, the second wing portion 222 is in contact with one end surface of the first rotating member 210, and the other end surface of the second rotating member 220 is in contact with the first rotating member 210. It can be prevented from leaving the internal space of the first rotating member 210 by being placed in contact with the seating portion of the. Since the size of the outer surface of the second rotating member 220 is implemented to be smaller than the size of the inner surface of the first rotating member 210, the second rotating member 220 has a second rotating member 220 along the inner surface of the first rotating member 210. It can be rotated inside the rotating member 220.

Meanwhile, the second wing portion 222 may be fixed to the second case 120. For example, an insertion space into which the second wing portion 222 can be inserted may be formed on the inner surface of the second case 120, protruding in the direction of the inner space, and the second wing portion 222 may be inserted into the insertion space. As a result, the second rotating member 220 can be fixed to the second case 120. At this time, the number of insertion spaces may correspond to the number of second wings 222.

The second rotating member 220 is fixed to the second case 120 and can be rotated simultaneously when an external force is applied to the second case 120. For example, when a user holds the second case 120 and applies an external force in one direction, the second rotating member 220 may rotate in the direction of the external force. In other words, the angle of the second case 120 can be adjusted in one direction by rotating the second rotating member 220. This will be described later.

A protrusion 221 may be formed on the outer surface of the second rotating member 220 in a direction perpendicular to the formation direction of the second wing portion 222. For example, the protrusions 221 may be formed on the upper and lower sides of the second rotating member 220, respectively, and may be implemented in a semicircular shape. Meanwhile, the second rotating member 220 is implemented to have a smaller diameter than the inner surface of the first rotating member 210, but the outermost diameter is within the inner surface of the first rotating member 210 due to the above-mentioned protrusion 221. It can be bigger than the side. According to this, the second rotating member 220 can be pressed into the inner surface of the first rotating member 210 by the protrusion 221. The second rotating member 220 on which the protrusion 221 is formed can be fixed and disposed inside the first rotating member 210 by fitting the protrusion 221 to the inner surface of the first rotating member 210. In addition, the protrusion 221 is pressed into contact with the inner surface of the first rotating member 210, so that the second rotating member 220 can be fixed without rotating when no external force is applied.

From now on, the operation in which the second case 120 is rotated by the user will be described with reference to the drawings. Referring to FIG. 5, the user can hold the second case 120 and rotate it in one direction. For example, when the user holds the second case 120 and applies an external force in one direction, the second rotating member 220 coupled to the second case 120 rotates in the direction in which the external force is applied, and the second case 120 also rotates. It can be. At this time, the second rotating member 220 is forcefully fitted to the inner surface of the first rotating member 210, so that it can be fixed at the rotated angle regardless of the angle unless the user applies an external force. According to this operation, the second case 120 is rotated as needed by the user, so an air discharge height suitable for the user can be set. In addition, when the case part 100 is used by being mounted on a cradle 600, which will be described later, there is an effect that the air discharge height can be adjusted to suit the position of the user's head. The second case 120 may be rotated 0 to 90 degrees with respect to the first case 110. If the second case 120 is not rotated based on the first case 110, the first case 110 and the second case 120 are arranged in the longitudinal direction to form a '1' shape. When the second case 120 is rotated 90 degrees based on the first case 110, the first case 110 and the second case 120 are rotated to have directions perpendicular to each other, forming 'a. 'It can be a shape.

Meanwhile, a stopper s that controls the rotation of the second rotating member 220 may be protruding from the first rotating member 210. Referring to FIG. 6, two or more stoppers (s) protruding toward the outer surface may be disposed on the first rotating member 210. This stopper (s) is in contact with a portion of the protruding structure that forms the insertion space of the second case 120 into which the second wing portion 222 is inserted, thereby preventing the second case 120 and the second rotating member 220 from being inserted. The turning radius can be adjusted. That is, the rotatable angle and rotatable direction of the second case 120 can be adjusted depending on the arrangement position (angle) of each stopper (s). This stopper (s) can prevent the second case 120 from rotating 360 degrees. According to this, cables present inside the second case 120 can be easily prevented from being twisted or cut.

The power member 300 is installed inside the second case 120 and can move the air existing outside the case unit 100 into the internal space of the case unit 100 through a plurality of inlet holes (h). there is. When the power member 300 is operated, the air existing outside the case portion 100 passes through the plurality of inlet holes (h) and flows into the inner space of the case portion 100, and the introduced air flows into the second case 120. It can be discharged in the direction of the other end of.

For example, the power member 300 may be implemented as a BLDC digital motor. BLDC digital motors are semi-permanent and can rotate at high speeds even at low power, so they are commonly used in cordless hair dryers. The BLDC digital motor intakes air existing outside the hair dryer and moves it inside the hair dryer, and moves the air inside the hair dryer in one direction to discharge it to the outside of the hair dryer. Hair dryer operation using such a BLDC digital motor is a very basic technology for hair dryers, so detailed explanation will be omitted.

The control member 400 is installed inside the other end of the second case 120 and can adjust the intensity and area of the internal air discharged toward the other end of the second case 120. Additionally, the control member 400 can reduce noise generated from the power member 300.

Referring to FIG. 7, the adjustment member 400 may be implemented in the shape of a disk with a thickness. The adjustment member 400 may be installed inside the second case 120 so that the other end faces the direction of the other end of the second case 120.

For example, the adjustment member 400 may be formed to correspond to the shape of the inner surface of the second case 120. The adjustment member 400 is disposed in the inner space of the second case 120 and can be fitted into the inner surface of the second case 120 to completely close the other end of the second case 120. Accordingly, internal air is prevented from being lost between the inner surface of the second case 120 and the adjustment member 400, and air discharge efficiency can be improved.

Referring to FIG. 8, a depression 410 may be formed in the adjustment member 400 that slopes downward toward the center as it moves from one end to the other end. That is, the depression 410 may be formed to be inclined toward the center along the air discharge direction when the adjustment member 400 is disposed in the second case 120. The internal air may move along the slope of the depression 410. Accordingly, the internal air can be easily prevented from being lost by moving in the outer direction of the adjustment member 400 or from being lost by hitting the inner surface of the second case 120. That is, the depression 410 can guide the direction of movement of the internal air so that the internal air is concentrated in the discharge direction.

Referring to (a) of FIG. 7, a guide portion 420 that guides the moving direction of air is formed in the central portion of the recessed portion 410 of the adjusting member 400, protruding in the direction of one end of the adjusting member 400. You can.

Referring to Figures 7 (b) and (c), a plurality of through holes 410h through which air moves through the recessed portion 410 of the adjusting member 400 are formed radially around the guide portion 420. It can be. At this time, each through hole 410h may be formed to have a length extending from the guide portion 420 toward the outside of the recessed portion 410. Additionally, each through hole 410h may be implemented in a shape whose width becomes wider as it moves from the guide portion 420 toward the outer side of the recessed portion 410. That is, the width of one end of each through hole 410h may be narrower than the width of the other end of each through hole 410h.

The air moving in the internal space may condense as it passes through each through hole (410h). According to this, the intensity of the air discharged to the other end of the second case 120, that is, the wind volume, can be increased.

In addition, the discharge area of the air passing through each through hole (410h) can be expanded according to the shape of each through hole (410h) whose width becomes wider as it moves from the guide part 420 to the outside of the recessed part 410. . In more detail, as the air passing through each through hole 410h moves toward the outside of the depression 410 along the width of each through hole 410h, a larger amount of air may be discharged. Due to this difference in the amount of discharged air, the area of discharged air can gradually increase in the outward direction.

Meanwhile, the width of one end of each through hole 410h is preferably 1/2 to 2/3 of the width of the other end of each through hole 410h. If the width of one end of each through hole (410h) is less than 1/2 of the width of the other end of each through hole (410h), loss may occur when air is discharged, and the width of one end of each through hole (410h) may be This is because if it exceeds 2/3 of the width of the other end of the through hole 410h, there is no difference in the amount of discharged air, so the increase in the area of discharged air may be minimal.

In addition, it is preferable that 10 to 12 of the plurality of through holes 410h described above are formed. This is because, when the plurality of through holes 410h are formed less than 10, the amount of air that can be discharged through each through hole 410h is reduced, thereby reducing the wind volume. On the contrary, if the plurality of through holes 410h are formed in excess of 12, the area through which the noise generated from the power member 300 can penetrate increases, so the effect of noise prevention may be significantly reduced.

The nozzle unit 500 is detachably coupled to the other end of the second case 120 and may be attached by magnetic force. The nozzle unit 500 provides an air passage in order to provide concentrated air discharged from the second case 120 to the user's hair, and may have an internal space and openings formed at both ends. A plurality of magnetic members 510 that form a magnetic field may be disposed at one end of the nozzle unit 500.

In addition, a plurality of first magnetic coupling members 121 that can be magnetically coupled to the magnetic member 510 may be disposed at the other end of the second case 120. The first magnetic coupling member 121 is disposed in a position facing each other when the nozzle part 500 is in contact with the second case 120 so that it can be magnetically attached to the magnetic member 510 of the nozzle part 500. It is desirable to be

For example, the magnetic member 510 of the nozzle unit 500 may be implemented as a magnet, and the first magnetic coupling member 121 may be implemented as a material that sticks to the magnet. Conversely, if the magnetic member 510 of the nozzle unit 500 is implemented as a material that sticks to a magnet, the first magnetic coupling member 121 may be implemented as a magnet. Alternatively, both the magnetic member 510 and the first magnetic coupling member 121 may be implemented as magnets, and in this case, the magnetic member 510 and the first magnetic coupling member 121 may have different electrodes.

Meanwhile, referring to FIG. 9, the magnetic member 510 and the first magnetic coupling member 121 may be formed with protruding and recessed irregularities to improve fixing force. For example, cylindrical protruding irregularities may be formed on the magnetic member 510, and recessed irregularities corresponding to the shape and size of the protruding irregularities may be formed on the first magnetic coupling member 121. The protruding irregularities of the magnetic member 510 can be inserted into the recessed irregularities of the first magnetic coupling member 121 and firmly fixed. According to this, the coupling force between the nozzle unit 500 and the second case 120 can be improved. That is, the nozzle unit 500 and the second case 120 can be prevented from being separated due to vibration generated while the user uses the hair dryer.

The shapes of the above-mentioned protruding and recessed protrusions are not limited to the shapes shown in FIG. 9, and may be made into any shape as long as they can be implemented as protruding or recessed shapes and inserted into and combined with each other.

Referring to FIG. 2, the cradle 600 may be provided with a holding space into which the other end of the first case 110 can be inserted and an attachment space into which the nozzle unit 500 can be attached and detached.

For example, the cradle 600 includes a main body 610 implemented in a cylindrical shape, and an insertion hole corresponding to the shape of the outer surface of the first case 110 is formed in the main body 610 to A holding space into which the end can be inserted may be provided.

Additionally, an attachment space into which the nozzle unit 500 can be attached and detached may be extended to the main body 610 of the cradle 600. In the attachment space, a plurality of second magnetic coupling members that can be magnetically coupled to the magnetic member 510 of the nozzle unit 500 may be disposed so that the nozzle unit 500 can be attached or detached.

For example, the magnetic member 510 of the nozzle unit 500 may be implemented as a magnet, and the second magnetic coupling member may be implemented as a material that sticks to the magnet. Conversely, if the magnetic member 510 of the nozzle unit 500 is implemented as a material that sticks to a magnet, the second magnetic coupling member may be implemented as a magnet. Alternatively, both the magnetic member 510 and the second magnetic coupling member may be implemented as magnets, and in this case, the magnetic member 510 and the second magnetic coupling member may have different electrodes.

The second magnetic coupling members are provided in the same number as the magnetic members 510 so that they can be coupled to the magnetic members 510 when the nozzle unit 500 is disposed in the attachment space 610s, and are arranged in positions opposite to each other. You can. According to this, the nozzle unit 500 is magnetically coupled to the attachment space and can be prevented from being separated from the attachment space by external force. Additionally, the user can easily mount or remove the nozzle unit 500, thereby improving user convenience.

According to the cradle 600 described above, the user can mount the case portion 100 on the cradle 600 by inserting the other end of the first case 110 into the mounting space of the cradle 600 described above. A portion of the first case 110 may be inserted into the mounting space and erected. Here, upright means that the first case 110 and the second case 120 are arranged to have a length in the vertical direction when the first case 110 and the second case 120 do not rotate with each other and are straight.

Meanwhile, a plurality of inlet holes h5 through which air communicates may be formed in the lower portion of the outer surface of the cradle 600. The plurality of inlet holes (h5) form a passage through which air existing outside the cradle 600 is moved to the internal space of the cradle 600, that is, the mounting space, so that the outside of the cradle 600 can communicate with the mounting space. According to these plurality of inlet holes (h5), when the case unit 100 is mounted and operated in the mounting space, air outside the cradle 600 can flow into the mounting space through the plurality of inlet holes (h5). The air flowing into the holding space may flow into the inner space of the case portion 100 through a plurality of inlet holes h1 and h2 formed at the other end of the first case 110.

That is, even if the first case 110 is mounted in the holding space and the plurality of inlet holes (h1, h2) are covered, air flows into the case portion 100 through the plurality of inlet holes (h5) formed in the cradle 600. may flow in. According to this, even if the case part 100 is mounted and used, the air intake efficiency can be prevented from being reduced.

A cable is connected to the cradle 600, and power can be supplied from the outside to supply power to the battery (b) placed inside the first case 110. A first charging terminal connected to a cable may be placed in the holding space of the cradle 600. At this time, it is preferable that the first charging terminal is in contact with the other end of the first case 110. A second charging terminal that supplies power to the battery (b) may be disposed at the other end of the first case 110 by contacting the first charging terminal. The second charging terminal is in contact with the first charging terminal and can supply power supplied from the outside to the battery (b). According to this, there is an effect that the battery (b) can be charged just by placing the case portion 100 on the cradle 600.

A wireless hair dryer 1000 that can be mounted and angle adjusted according to another embodiment of the present invention may include an ultrasonic wave generator. The ultrasonic generator may be disposed in the internal space of the second case 120 and may be implemented as an ultrasonic vibrator that generates ultrasonic vibration. For example, the ultrasonic generator may be disposed adjacent to the control member 400 and transmit ultrasonic vibration to the inner surface of the second case 120 and the control member 400. The transmitted ultrasonic vibration can reduce the adhesion of dust and foreign substances attached to the inner surface of the second case 120 and the control member 400. Dust and foreign substances with reduced adhesion can be removed from the inner space of the second case 120 to the outside of the second case 120 along the air discharged toward the other end of the second case 120.

Meanwhile, the ultrasonic generator may be implemented with a plurality of ultrasonic oscillators that generate different vibration magnitudes. This ultrasonic generator is disposed on the inner surface of the second case 120 and may be arranged to generate larger vibrations toward the other end of the second case 120. According to this, dust and foreign matter attached to the inner surface of the second case 120 can be moved to the other end according to the magnitude of vibration. According to this, even if air is not discharged, dust and foreign matter can be moved toward the other end of the second case 120 and discharged according to the magnitude of ultrasonic vibration.

The user can selectively operate the ultrasonic generator. For example, a button for operating the ultrasonic generator may be installed on the case unit 100, and the user may operate the ultrasonic generator by pressing the button with a finger. That is, when a user uses the hair dryer 1000 for hair care purposes, the ultrasonic generator may not operate. This is because if the ultrasonic generator is operated every time the hair dryer 1000 is used, dust existing inside the case portion 100 may be discharged to the user. Accordingly, the user can operate the ultrasonic generator only when using the hair dryer 1000 for the purpose of removing dust.

According to this, there is an effect in that dust that attaches and accumulates in the inner space of the case part 100 can be easily removed without disassembling the case part 100 or using a cleaning device.

Meanwhile, an anti-static material may be applied to the inner space of the second case 120. Accordingly, dust and foreign substances whose adhesion has been reduced due to ultrasonic vibration can be prevented from re-attaching to the inner surface of the second case 120.

The wireless hair dryer 1000 that can be mounted and angle adjusted according to another embodiment of the present invention may further include a plurality of sensors.

The plurality of sensors may include a distance detection sensor and a tilt detection sensor.

The distance sensor is disposed at the other end of the second case 120 and can detect the distance between the user and the second case 120. The distance detection sensor may be electrically connected to the power member 300. The distance detection sensor can stop the operation of the power member 300 when the distance between the user and the second case 120 is greater than a predetermined distance. Here, the predetermined distance may mean the distance when the user actually uses the hair dryer 1000. For example, the predetermined distance may be 50cm. According to this distance detection sensor, if the user leaves the hair dryer 1000 for a while or forgets to turn off the power, the operation of the power member 300 is automatically stopped, thereby saving power and preventing fire, etc. Risks can be prevented.

The tilt detection sensor is disposed on the cradle 600 and can detect the tilt of the cradle 600. The tilt detection sensor may be electrically connected to the power member 300. The tilt detection sensor detects the tilt of the cradle 600 and, when the tilt of the cradle 600 is greater than a preset value, determines that the cradle 600 has been overturned by an external force and stops the operation of the power member 300. At this time, the case portion 100 may be inserted and placed in the cradle 600, and the preset tilt value may be a value that differs by more than 50% from the minimum detected tilt value. According to this, when the case portion 100 is inserted into the cradle 600 and used, if the cradle 600 is overturned by other external force, the operation of the power member 300 is automatically stopped, so power can be saved and fire, etc. risks can be prevented.
