Therefore, a suction port (not shown) for suctioning of dust may be provided inside the housing 10, and the rotating part 700 performing a function of wiping the cleaning surface is provided with a dust suction port (not shown). It may be provided at a position that does not interfere with the suction path.

The rotating part 700 may be rotatably fixed to the housing 10 and may rotate or wipe the cleaning surface in a fixed state.

The rotating part 700 may be provided symmetrically to the left and right with respect to the extension tube 50 so as not to interfere with the suction path of the dust sucked into the extension tube 50 .

A detachable operation member 51 may be provided in the extension tube 50 , and a user may separate the housing 10 from the extension tube 50 through the detachable operation member 51 . The detachable operation member 51 of this embodiment has a structure that separates the extension tube 50 and the housing 10 by pressing and pushing the user, but is not necessarily limited to this structure and may be provided as a switch structure.

A suction pipe 53 and a connecting member 55 may be provided between the extension pipe 50 and the housing 10 .

The connection member 55 guides the dust sucked into the housing 10 to the extension pipe 50 . And the connecting member 55 may be formed of an elastic material.

The housing 10 is rotatably provided on the extension tube 50 to effectively clean the blind spot of the cleaning surface. In detail, by rotating the housing 10, the user can easily clean the blind spot by rotating the housing 10 without twisting the entire cleaner to clean the blind spot, such as the edge of the cleaning surface.

Therefore, as the connecting member 55 is provided with an elastic material, it is possible to facilitate rotation of the housing 10 .

The connecting member 55 is a member provided to surround a part of the outer surface of the suction pipe 53 , and the connecting member 55 is provided at a portion where the extension pipe 50 and the housing 10 are connected.

It is possible to prevent the suction pipe 53 from being damaged by the connection member 55 .

More specifically, in general, the extension tube 50 is extended to form a predetermined length, and a handle portion (not shown) is provided on the extension tube 50 to perform cleaning while the user holds the handle portion.

When the suction pipe 53 having elastic force is provided between the extension tube 50 and the housing 10 , even if the user pushes the extension tube 50 , the force may not be transmitted to the housing 10 well. . Accordingly, the housing 10 may rotate differently from the intended direction of the user.

Therefore, when the connecting member 55 is provided, when the user pushes the extension tube 50, the front end of the extension tube 50 and the front end of the connecting member 55 come into contact with each other to facilitate direction manipulation of the housing 10. can do.

The housing 10 forms the exterior of the nozzle head of the cleaner, and the housing 10 may include a base member 13 and a case 11 .

A water tank 100 , a motor 500 , and the like may be provided in the inner space of the housing 10 formed by combining the base member 13 and the case 11 . And it goes without saying that a suction port penetrating the inner space is provided to suck dust.

Since the case 11 may be made of a transparent material, the user can check the inner space of the housing 10 without removing the case 11 .

And the base member 13 may be provided with a manipulation unit 70 . The operation unit 70 performs an operation to turn on and off the power of the coil module 310, which will be described later, to operate the amount of heat generated by the heating member 330, or to turn on and off the rotation operation of the rotating unit 700. Can be performed. have.

Preferably, the operation unit 70 controls the operation of the coil module, and the operation control may mean an operation of turning on and off the power of the coil module 310 . Of course, the manipulation unit 70 may be formed in a portion of the extension tube 50 to be formed close to a position held by the user.

However, since the coil module 310 is provided inside the housing 10 , the provision of the manipulation unit 70 on the exterior of the housing 10 enables the user to intuitively operate the coil module 310 .

In addition, since the manipulation unit 70 and the coil module 310, which is an object controlled by the manipulation unit 70, are formed in the housing 10, the manipulation unit 70 and the coil module 310 are electrically and physically connected. Since the configuration can be simplified, assembly and manufacturing can be easy.

4 is a perspective view showing the internal configuration of FIG. 2 , FIG. 5 is a diagram illustrating a configuration in which steam or water is supplied to the rotating part of FIG. 4 , and FIG. 6 is a view expressing the rotating part, the nozzle and the hose of FIG. 4 .

Hereinafter, it will be described with reference to FIGS. 4 to 6 .

A water tank 100 for storing water is provided inside the housing 10 .

The water tank 100 may be provided in various shapes to store the water supplied to the rotating part 700 , and may be provided in a partially recessed shape depending on the configuration provided inside the housing 10 .

The water tank 100 is provided with a plurality of holes 101 communicating with the space in which the water is stored. The hole 101 may be provided on the upper surface of the water tank 100 . The upper surface of the water tank 100 means a surface in contact with the water when the water is stored in the water tank 100 to the maximum.

As the hole 101 is provided on the upper surface of the water tank 100 , it is possible to sufficiently secure a storage capacity of water for supplying steam to the rotating part 700 by heating the inside of the water tank 100 .

This is because, if the hole 101 is provided on the side of the water tank 100 , the capacity of the water stored in the water tank 100 may be limited by the location of the hole 101 .

In addition, in this embodiment, the water in the water tank 100 may be heated to supply high-temperature water to the rotating unit 700 . Even in this case, the hole 101 may be formed in the above-described position, and it is preferable to supply water by inserting the hose 200 deeper into the inner space of the water tank 100 .

The hose 200 may be provided with one side connected to the hole 101 and the other side passing through the outer surface of the housing 10 . That is, the hose 200 forms a flow path for moving steam or water inside the water tank 100 to the rotating part 700 .

Accordingly, the other side of the hose 200 passes through the outer surface of the housing 10 , and its position is a position covered by the area of the rotating part 700 .

In detail, the rotating part 700 is fixed to the rotating shaft 531 penetrating the housing 10 and rotates at a predetermined distance from the outer surface of the housing 10 . Therefore, the position where the hose 200 passes through the outer surface of the housing 10 is spaced apart from the rotation shaft 531 and is formed on a part of the outer surface of the housing 10 covered by the rotation unit 700 . desirable.

In addition, the hose 200 may be provided with a nozzle 210 and a tip connected thereto so that the nozzle 210 passes through the outer surface of the housing 10 . Therefore, water moving along the hose 200 is sprayed through the nozzle 210 , so that it can be uniformly supplied to the rotating part 700 .

Of course, the nozzle 210 is spaced apart from the rotation shaft 531 , and it is preferable that a part of the outer surface of the housing 10 covered by the rotation part 700 penetrates the outer surface of the housing 10 .

A plurality of the rotating parts 700 may be provided to increase the cleaning area, and a plurality of hoses 200 may also be provided to supply steam or water to each of the rotating parts 700 .

When the two rotating parts 700 are provided as in the present embodiment, two motors for transmitting rotational force to each of the rotating units are provided to control the rotational speed of each rotating unit differently.

However, since the rotating part 700 performs a function of wiping the cleaning surface by rotating, a single motor 500 is provided rather than a plurality of motors in the housing 10 to control the rotation speed differently. It is preferable to secure a space inside the housing 10 .

This is because the space of the housing 10 is limited, and the cleaning time can be sufficiently secured only when the capacity of the water tank 100 is increased by utilizing the limited space.

Accordingly, the motor 500 for generating the rotational force of the rotating part 700 may be provided, and the motor 500 and the rotating shaft 531 may be provided such that the gears 510 and 530 are meshed with each other.

In order to effectively transmit the power of the motor 500 , the radius of the gear 510 is preferably larger than the radius of the gear 530 .

The heating member 330 is provided inside the water tank 100 or is provided to form at least one surface of the water tank 100 and generates heat by the induction magnetic field generated by the coil 313 accommodated in the coil module 310. .

As the heating member 530 generates heat, the water inside the water tank 100 is heated to supply steam or high-temperature water to the rotating part 700 by the above-described structure.

The principle of the coil module 310 heating the heating member 530 will be described as follows.

A coil 313 is formed by winding the wire, and thus the coil 313 has a center.

When a current is supplied to the wire, the current flows while rotating with respect to the center due to the shape of the coil 313 . Accordingly, a magnetic field in a vertical direction passing through the center of the coil 313 is generated.

At this time, when an AC current having a different phase difference passes through the coil 313 , an AC magnetic field whose direction changes with time is formed. The AC magnetic field generates an induced magnetic field in a direction opposite to the AC magnetic field in an adjacent conductor, and a change in the induced magnetic field generates an induced current in the conductor.

The induced current and the induced magnetic field may be understood as a form of inertia with respect to changes in electric and magnetic fields.

That is, the heating member 330 is provided as a conductor, and the heating member 330 generates an eddy current or eddy current, which is a type of induced current due to the induced magnetic field generated in the coil 313 .

At this time, the eddy current is dissipated by the resistance of the heating member 330 and converted into heat. That is, as a result, the heating member 330 is heated by the heat generated by the resistance, and the temperature of the water inside the water tank 100 rises as the heating member 300 is heated.

In other words, when the heating member 330 is provided with a conductor made of a magnetic material such as iron (Fe), it can be heated by the AC current of the coil 313 provided in the coil module 310 .

Therefore, when the heating member 330 is provided inside the water tank 100 as described above, the heating member 330 is spaced apart from the bottom surface of the water tank 100 by a predetermined distance and is fixed inside the water tank 100, or the water tank 100 ) may be provided in contact with the bottom surface, or may be provided while forming the bottom surface of the water tank 100 .

And it is preferable that the area formed by the heating member 330 is included in the area formed by the coil module 310 . That is, the area of the heating member 330 is preferably the same as the area formed by the coil 313 or larger than the area formed by the coil 313 .

This is because the water in the water tank can be heated more effectively only when the temperature rises uniformly over the entire area of the heating member 330 . The shape of the coil will be described later in detail with reference to FIGS. 8 to 10 .

Looking at the configuration in which steam or high-temperature water (s) is supplied to the rotating unit with reference to FIGS. 5 and 6 , the rotating unit 700 rotates on the cleaning surface in the rotating direction r with respect to the rotating shaft 531 .

The configuration of the hose 200 and the nozzle 210 is spaced apart from the rotation shaft 531 by a predetermined distance to spray steam or water (s) onto a partial area of the rotation unit 700 . Of course, since the hose 200 is provided inside the housing 10, and the nozzle 210 is fixed through the inner space of the housing 10, the position at which steam or water (s) is supplied is fixed. .

Therefore, the position to which steam or water (s) is supplied is fixed, and by rotating the rotating part 700 in the rotational direction r with respect to the rotating shaft 531 , steam or water may be uniformly supplied to the rotating part 700 . can

The rotation unit 700 may include a fixing member 710 that is connected to the rotation shaft 531 and rotates, and a cleaning member 750 that is detachably provided to the fixing member 710 . In addition, the cleaning member 750 may be caught and fixed to the fixing member 710 by a plurality of hooks 730 protruding from the outer surface of the fixing member 710 .

The rotating unit 700 is a member that performs a function of wiping the cleaning surface while rotating, and the rotating unit 700 itself is detachably fixed to the rotating shaft 531 so that a user may replace the rotating unit 700 .

And as in this embodiment, the rotation shaft 531 and the fixing member 710 are connected for structural stability, and the cleaning member 750 is detachably fixed to the fixing member 710 so that the user can use the cleaning member ( 750) may be replaced.

The cleaning member 750 may include various materials and shapes capable of wiping the cleaning surface and absorbing steam or water (s).

In addition, a bearing 533 may be provided in the housing 10 so that the rotation shaft 531 may be provided through the bearing 533 .

7 is a view showing the inside of the water tank of FIG.

Hereinafter, it will be described with reference to FIG.

The water tank 100 may be formed with a hole 101 to which the hose 200 is connected, and the hole 101 is formed on the uppermost surface of the water tank 100 as described above for water contained in the water tank 100 . It is preferable not to limit the amount.

In addition, the water tank 100 may be provided with an outlet 105 and a blowing fan 110 for discharging the air inside the water tank 100 .

As the heating member 330 generates heat in the water tank 100 , a high temperature and high humidity environment is formed, so mold, harmful bacteria, etc. may be propagated inside the water tank 100 and discharged to the user's space. Therefore, it is necessary to dry the inside of the water tank 100 .

Since the inside of the water tank 100 is in communication with the outside by the hole 101 , only the outlet 105 is sufficient to dry the inside of the water tank 100 .

In addition, a water level sensor 130 may be provided in the water tank 100 to prevent the water level L from being formed higher than the outlet 105 . Therefore, the user can supply water to the water tank 100 in a state where only the case 11 is removed, and the amount of water supplied to the inside of the water tank 100 can be detected through the water level sensor 130 .

Of course, since a water inlet communicating with the water tank 100 is formed in the case 11, a user may supply water to the water tank through the inlet, and the water level detected through the water level sensor 130 is separate. It may be displayed to the user through a display (not shown), or the user may be informed through sound or the like.

Meanwhile, a separate suction port 103 may be formed in the water tank 100 to facilitate the flow of air discharged to the discharge port 105 . Preferably, the inlet 103 is formed at different positions at the same height as the outlet 105 in the water tank 100 to further increase the water level L.

In addition, a partition wall 150 for guiding the flow of air is installed inside the water tank 100 to form a flow path through which the air sucked into the inlet 103 is discharged to the outlet 105 .

The partition wall 150 is provided between the inlet 103 and the outlet 105 .

The partition wall 150 may extend from one surface of the water tank to the other surface, and the front end of the partition wall 150 may extend to be provided at a position spaced apart from the other surface of the water tank 100 by a predetermined distance. Accordingly, a flow path may be formed on the other surface of the water tank 100 and the front end of the partition wall 150 to discharge air.

In addition, the inlet 103 and the outlet 105 are located at different heights from the inner surface of the water tank 100 , and a partition 150 is formed between the inlet 103 and the outlet 105 between the inner surface of the water tank 100 and the flow path. It is preferable to form

Because when the inlet 103 and the outlet 105 are formed at the same height on the inner surface of the water tank 100 , in order to partition the flow path by the barrier wall 150 , the barrier wall 150 is formed along the height direction of the water tank 100 . Since it is provided across the inside of the water tank, the position of the hole 101 must be biased by the partition wall 150, and the amount of water stored in the water tank can be reduced by the volume of the partition wall. Other disadvantages may occur.

Accordingly, the inlet 103 and the outlet 105 are formed at different heights on one surface of the inside of the water tank, and the partition wall 150 is located between the inlet 103 and the outlet 105 of the inner surface of the water tank. It is formed to extend to the other surface inside the water tank, and the front end of the partition wall 150 may be spaced apart from the other surface inside the water tank by a predetermined distance to form a flow path.

8 to 10 show the heating temperature rise distribution of the coil 313 having different vertical lengths and the heating member 330 according to the vertical width of the coil 313 .

Hereinafter, it will be described with reference to FIGS. 8 to 10 .

Since the strength of the magnetic field decreases with distance, it is advantageous in terms of energy efficiency to narrow the gap between the coil module 310 and the heating member 330 .

Accordingly, the coil 313 is preferably formed as a single layer as shown in the drawings. That is, it is preferable that the wire is wound in a single layer rather than being wound in a plurality of layers.

Because, when the wire is wound in a plurality of layers, a gap is inevitably generated between the wire and the wire. Therefore, a distance equal to the gap is inevitably generated between the wire of the bottom layer and the wire of the upper layer of the bottom layer. In this case, the distance between the coil of the upper layer of the bottom layer and the tank must be increased.

Of course, even if such a gap can be physically excluded, the efficiency is inevitably reduced because the distance between the coil of the upper layer of the bottom layer and the tank increases as the number of coil layers increases.

Therefore, the coil 313 is preferably formed as a single layer. This means that the area of the coil 313 in contact with the heating member 330 can be increased as much as possible while using the same wire length.

In addition, the coil 310 may be provided in the form of a track forming four straight sections 3131 , 3132 , 3133 , 3134 and curved sections 3135 , 3136 , 3137 and 3138 formed between the straight sections.

And in the graph of each figure, the vertical axis indicates each position of the heating member 330, '1' is one side of the heating member 330, '5' represents the other side of the heating member 330, '2' ' to '4' represents the interval between them. That is, the heating member 330 forms a width extending from '1' to '5'.

In the graph, the horizontal axis represents the temperature increase rate of the heating member 330 .

Hereinafter, the width of the coil 313 and the rate of temperature increase of the heating member 330 to be described are relatively compared to each of the coils 313 illustrated in FIGS. 8 to 10 .

8 is a case in which the heating member 330 is heated using a coil having the widest width, FIG. 9 is a case in which the heating member 330 is heated using a coil having a medium width, and FIG. This is a case in which the heating member 330 is heated using a coil having a width.

Of course, it is preferable that the area formed by the coil is smaller than the area of the heating member 330 .

The temperature increase rate of the heating member by the coil of FIG. 8 shows a uniform temperature increase rate over the entire area of the heating member 330 compared to other coils.

On the other hand, the temperature increase rate of the heating member by the coil of FIGS. 9 and 10 has a significant difference between the width of the heating member 330 and the temperature increase rate of the central portion.

That is, it can be seen that both widths of the heating member 330 and the central portion are relatively uniformly heated as the longitudinal width of the coil is increased on the assumption that the area of each coil is the same. This can be attributed to the fact that a large portion of the area of the coil corresponding to the center of the heating member is moved to both widths of the heating member.

That is, the area of the heating member 330 is preferably covered by the area formed by the coil 313 .

And the longitudinal width of the coil and both widths of the heating member are affected by the shape of the water tank (100). The housing 10 may be provided with an exterior that forms a predetermined width to increase the cleaning area, and the shape of the water tank 100 may be considered in consideration of the exterior of the housing.

As a result, the coil 313 has a vertical axis forming the major axes 3131 and 3132 , a horizontal axis forming the minor axes 3133 and 3134 , and curved portions 3135 , 3136 , 3137 and 3138 connecting the major axis and the minor axis. It may be provided in the shape of a provided track.

The curved portion may have the same radius of curvature and may be formed to fill the corner of the rectangle as much as possible. Therefore, the amount of magnetic field that can be reduced by the shape of the coil at both ends of the heating member can be maximally compensated by matching the radius of curvature of the curved part.

Although representative embodiments of the present invention have been described in detail above, those of ordinary skill in the art to which the present invention pertains will understand that various modifications are possible without departing from the scope of the present invention with respect to the above-described embodiments. . Therefore, the scope of the present invention should not be limited to the described embodiments and should be defined by the claims described below as well as the claims and equivalents.
