The air wash inlet 31 is formed on a side surface of the water tank body 320. The air wash inlet 31 is formed 360 degrees forward with respect to the water tank body 320. The air wash inlet 31 communicates with the humidifying connection passage 105.

The water tank extender (380) guides the water flowing down from the inner side of the visual body (210) into the water tank (300). Dripping noise can be minimized by guiding the water flowing down from the visual body 210.

The water tank extender (380) is fastened to the lower end of the visual body (210).

In this embodiment, the air wash inlet 31 is formed through the structure of the water tank body 320. The water tank body extension unit 380 may be disposed on the visual body 210 to form the air wash inlet 31. [ A part of the plurality of water tank body extensions 380 is disposed in the water tank 300 and the rest of the water tank body extensions 380 is disposed in the visual body 210 to form an air wash inlet 31). In addition, unlike the present embodiment, the air wash inlet 31 can be formed in a separate structure different from the visual body 210 and the water tank 300. Also, unlike the present embodiment, an opening surface is formed in the visual body 210 to form an air wash inlet 31, and an opening surface may also be formed in the water tank 300 to form the air wash inlet 31.

The air wash inlet 31 may be formed through a combination of the water tank 300 and the visual body 210.

The air wash inlet 31 is disposed on the side of the air wash module 200 and is connected to the humidification channel 106. The air wash inlet 31 may be connected to or connected to the humidification connection passage 105.

The watering unit (400) has a function of supplying water to the humidifying medium (50). The watering unit 400 has a function of visualizing the humidification process. The watering unit 400 has a function of implementing a lane view inside the air wash module 200.

The watering unit 400 sucks the water inside the water tank by rotating the water ring housing 800, sucks the sucked water upward, and injects the pumped water outward in the radial direction. The watering unit 400 includes a watering housing 800 that sucks water inward, sucks the sucked water upward, and then discharges the sucked water in a radially outward direction.

In this embodiment, the water ring housing 800 is rotated to spray water. Water may be sprayed by using a nozzle instead of the water ring housing 800, unlike the present embodiment. Water can be supplied to the humidifying medium 50 by spraying water from the nozzle, and the rain view can be similarly implemented. According to the embodiment, water may be sprayed from the nozzle and the nozzle may be rotated.

The water sprayed from the water ring housing 800 sweeps the humidifying medium 50. The water sprayed from the water ring housing 800 may be sprayed toward at least one of the visual body 210 and the humidifying medium 50.

The water sprayed toward the visual body 210 may implement a lane view. The water sprayed toward the humidifying medium 50 is used to humidify the filtered air. Water may be sprayed toward the visual body 210 to implement a rain view, and water flowing in the visual body 210 may be wetted with the humidifying medium 50.

In this embodiment, a plurality of jetting openings having different heights are arranged in the watering housing 800. The water ejected from any one jetting port forms a droplet on the inner surface of the visual body 210 to implement the lane view and the water discharged from the other jetting port wets the humidifying medium 50 to be used for humidification.

The water ring housing 800 injects water toward the inner surface of the visual body 210 and the water flows down along the inner surface of the visual body 210. A droplet of water droplets is formed on the inner surface of the visual body 210, and the user can see the droplet through the visual body 210.

In particular, the water flowing from the visual body 210 is used to humidify the humidifying medium 50 by wetting it. The humidifying medium 50 is wetted by the water sprayed from the watering housing 800 and the water flowing from the visual body.

The visual body 210 is coupled to the water tank 300 and is located above the water tank 300. At least a part of the visual body 210 is formed of a material capable of viewing through the inside.

The display module 160 may be disposed outside the visual body 210. The display module 160 may be coupled to either the visual body 210 or the upper body 120.

The display module 160 is disposed on the line of sight of the lane view. In the present embodiment, the display module 160 is disposed on the upper body 120.

When the air wash module 200 is mounted, the outer surface of the visual body 210 is brought into close contact with the display module 160. At least a part of the surface of the display module 160 may be formed or coated with a material reflecting light.

The droplet formed on the visual body 210 is also projected on the surface of the display module 160. Thus, the user can observe the movement of the droplet in two places of the visual body 210 and the display module 160.

The water tank 300 is formed with an air wash inlet 31 through which air is communicated. The air wash inlet 31 is located between the connection passage 103 and the humidification passage 106. The air wash inlet 31 is an outlet of the connection passage 103 and an inlet of the humidification passage 106.

The filtered air supplied from the air clean module 100 flows into the air wash module 200 through the air wash inlet 31.

The humidifying medium 50 includes a water bath humidification medium 51 disposed at an inlet of the humidification channel 106 and a discharge humidifying medium 55 disposed at an outlet of the humidification channel 106. The outlet of the humidification channel (106) and the inlet of the discharge channel (107) are connected to each other. Therefore, the discharge humidifying medium 55 may be disposed in the discharge flow path 107.

Since the connection passage 103, the humidification passage 106, and the discharge passage 107 are not formed through a structure such as a duct, it is difficult to clearly distinguish the boundaries. However, when the humidification flow path 106 in which humidification is performed is defined between the water tank humidifying medium 51 and the discharge humidifying medium 55, the connecting flow path 103 and the discharge flow path 107 are naturally defined.

The connection passage 103 is defined between the blowing housing 150 and the water tank humidifying medium 51. The discharge flow path 107 is defined after the discharge humidification medium 55. .

In the present embodiment, the water tank humidifying medium 51 is disposed in the air wash inlet 31 of the water tank 300.

The water tank humidifying medium 51 may be located on at least one of the same plane, outside, or inside as the air wash inlet 31. It is preferable that the water tank humidifying medium 51 is located inside the air wash inlet 31 because water is humidified for humidification.

It is preferable that water flowing down after wetting the water tank humidifying medium 51 is stored in the water tank 300. It is preferable that water flowing down after wetting the water tank humidifying medium 51 is disposed so as not to flow out of the water tank 300.

Thus, the water tank humidifying medium 51 provides humidification for the filtered air passing through the air wash inlet 31.

The filtered air is humidified by the water that is spontaneously evaporated in the humidifying medium (50). The natural evaporation refers to the evaporation of water in the absence of additional heat. As the contact with air increases, as the flow rate of air increases, the lower the pressure in the air, the more natural evaporation is promoted. The natural evaporation may be referred to as natural vaporization.

The humidifying medium 50 promotes natural evaporation of water. In this embodiment, the humidifying medium 50 is wetted with water, but is not immersed in the water tub 300. [

The water tank humidifying medium 51 and the discharge humidifying medium 55 are not always wetted with water stored in the water tank 300 because they are separated from the water stored in the water tank 300. [ That is, the water tank humidifying medium 51 and the discharge humidifying medium 55 are wetted only when operated in the humidifying mode, and when the water tank humidifying medium 51 and the discharge humidifying medium 55 are operated in the air clean mode, As shown in Fig.

The water tank humidifying medium 51 covers the air wash inlet 31 and air flows into the water tank 300 through the water tank humidifying medium 51.

The water dropped into the operation water inlet 241 flows along the surface of the water supply cap 1430 and temporarily stored in the water supply reservoir 1441 and then flows to the lower portion of the discharge humidification medium housing 1440 through the water supply port 1445 .

The water that has passed through the water supply port 1445 falls into the interior of the visual body 210 and then falls to the upper portion of the watering housing 800.

When the watering housing 800 is rotated, the water supplied through the upper water supply is scattered to the inner side of the visual body 210. Thereafter, the scattered water flows along the inner side of the visual body 210 and is stored in the water tank 300, thereby raising the water level of the water tank 300.

The control unit determines the signal sensed by the water level sensor 135 and displays the water level of the water tank 300 in the water level display unit 247.

The user can not immediately see the water level in the water tank 300 at the time of the upper water supply but can immediately check the water level raised through the water level indicator 247 disposed around the operation water inlet 241. [

Since the user can confirm the water level through the water level display part 247 during the upper water supply, the user can adjust the upper water supply flow rate.

The power supply unit 185 rectifies and smoothes the supplied power, changes the voltage to a voltage necessary for operation, and supplies the power to each unit. Further, the power supply unit 185 supplies power to the top cover assembly which is detached from the body. The power supply unit 185 includes a wireless power transmission unit provided in the base body and a wireless power reception unit provided in the top cover assembly to supply operating power to the top cover assembly in a non-contact manner.

In addition, the controller 190 determines that the top cover assembly is mounted on the visual body, and controls the power to be supplied to the top cover assembly through the wireless power transmitter.

The control unit 190 receives the signal of the input unit included in the top cover assembly through the communication unit, and sets the operation mode accordingly to control the operation. When the stand-by mode is set from the input unit of the top cover assembly, the control unit 190 applies a control command to the power source unit so that the visual body operates as a standby voltage, and the top cover assembly also controls the supplied voltage.

11 is a block diagram schematically showing a control configuration for power supply and communication of the humidification cleaner.

11, the power supply unit 185 supplies operation power to the base body 110 and further includes a wireless power transmission unit 410 and a wireless power reception unit 420, (230).

The top cover assembly 230 is provided with an operation module including an input unit and a display unit, and the operation module and the display unit are operated by receiving the power received by the wireless power receiving unit.

The control unit 190 determines whether the top cover assembly is detached from the visual body in response to the detection signal of the cover sensing unit 440 and controls the operation of the wireless power transmitting unit 410 accordingly.

When the top cover assembly is detached, the controller 190 disables the power supply because the power supply is not possible, so that the power supply is not unnecessarily applied.

In addition, when the standby mode is set through the input unit, the controller 190 controls the power unit to operate in the standby mode. In order to receive a signal in the standby mode, the controller 190 applies a voltage according to the standby mode to the top cover assembly. That is, when the power supplied to the top cover assembly is cut off in the standby mode, since the input unit is not operated, the input according to the operation setting or the standby mode can not be received. Therefore, So as to control the power source unit.

In the top cover assembly, a voltage is applied to the input unit and the second display unit through the wireless power receiving unit, and the input / output control units 246 and 470 for controlling the input / output control the output of the second display unit in response to a signal input through the input unit. And transmits the data to the base body via the third communication unit.

The second communication unit inputs the received data to the control unit 190, and controls the operation according to the data input to the control unit.

In addition to a communication unit for communication with the outside, a second communication unit is provided in the base body and a third communication unit is provided in the top cover assembly in order to transmit and receive data between the base body and the top cover assembly. The second communication unit and the third communication unit are wirelessly connected via Bluetooth, Radio Frequency Identification (RFID), infrared data association (IrDA), etc., but other wireless communication methods such as WIFI may be applied .

In the normal mode, when the standby mode is set through the input unit, the input / output control units 246 and 470 transmit data according to the standby mode setting through the third communication unit, and the controller 190 sets the air clean module (100) and the air wash module (200). In addition, the controller 190 controls the voltage applied from the wireless power transmitter to the top cover assembly. Thereby, the standby mode is set, and the voltage applied through the wireless power receiving unit is changed to the low voltage according to the standby mode.

The voltage according to the standby mode is used to receive the key input of the input unit, and the power supply is interrupted for other operations. In some cases, some of the second display units may be operated. For example, among the second display units, it is possible to keep the notification display informing the standby mode setting state, but all the remaining displays can be turned off.

When the standby mode is canceled through the input unit, the input / output control units 246 and 470 transmit data according to the standby mode release through the third communication unit, and the control unit 190 releases the standby mode, And controls the air clean module and the air wash module to operate according to the respective settings. In addition, the control unit 190 applies a normal voltage from the wireless power transmission unit. As the normal voltage is applied to the top cover assembly, all operations are normally performed.

FIG. 12 is a simplified block diagram illustrating the configuration of a wireless power transmission unit for supplying power to a top cover assembly, FIG. 13 is a block diagram of a wireless power reception unit and control configuration of the top cover assembly, 14 is a diagram schematically showing a circuit configuration according to the wireless power transmission of the present invention.

As shown in FIGS. 12 to 14, a wireless power transmission unit is provided in the base body, and a wireless power receiving unit is provided in the top cover assembly. Thus, power is supplied to the top cover assembly, which is separated from the visual body, .

The control unit 190 receives the cover detection signal, determines whether the top cover assembly is mounted on the visual body or is separated, and controls power supply through the wireless power transmission unit on and off.

The wireless power transmission unit 410 includes a filter unit 413, a regulator 414, a switching unit 415, a power transmission unit 416, a current sensing unit 412, and a power transmission control unit 411.

The filter unit 413 filters the input power source, that is, the electric current, and filters the electric current of a predetermined magnitude or more. The filter unit 413 blocks the inrush current.

The regulator 414 generates a voltage to be transmitted from the power transmission unit to the power transmission unit according to the control command of the control unit. The regulator transfers the voltage according to the setting. For example, the regulator 414 outputs a voltage of 12V in normal operation and a voltage of 6.5V in standby mode in response to a control command. At this time, the voltages at the first point PV1 are 12V and 6.5V, respectively.

The current sensing unit 412 is connected between the regulator 414 and the switching unit 415 and senses a current flowing from the regulator to the switching unit. The current sensing unit senses an overcurrent and inputs a sensing signal to the power transmission control unit.

The switching unit 415 applies a wireless power signal to the power transmission unit as a plurality of switches are turned on and off according to the switching control signal of the power transmission control unit. The switching unit may be connected to both ends of the coil of the power transmission unit.

In the power transmission unit 416, current is applied to the coil by the operation of the switching unit, and electricity is induced. Preferably, the coil of the power transmission unit is provided so as to face the rear surface of the switching unit, the power transmission control unit, and the power receiving unit.

The power transfer control unit 411 applies switching control signals (PWM control signals) of different types in the normal mode and the standby mode to the switching unit.

For example, the power transmission control unit 411 applies a switching control signal of a designated frequency in a normal mode and a switching control signal for period switching in a standby mode.

The power transfer control unit applies the PWM control signal of the fixed frequency to the switching unit in the normal mode and performs the high efficiency interval switching at the frequency lower than the normal mode in the standby mode.

The power transmission control unit divides the signal interval into the operation interval and the stop interval, and generates the switching control signal so that the switching unit operates in the operation interval. The power transmission control unit applies a switching control signal of a first frequency to the switching unit when the normal mode is set, and performs a period switching at a frequency lower than the first frequency when the standby mode is set. Lt; / RTI >

In the high-efficiency section switching, since the ineffective circulation current due to the LC resonance is large, the power consumed in the standby mode is increased. Therefore, in order to solve this problem, PWM control is performed by dividing the switching period and the stopping period. The power transmission control unit divides the interval so that the lengths of the operation interval and the stop interval are different, and PWM control is performed in the operation interval. For example, the operation interval of 2 ms and the stop interval of 8 ms are repeated so that the PWM control can be performed only during the operation period.

When the standby mode is set, the power transmission control unit generates the switching control signal with a duty lower than that of the normal mode, and adjusts the ratio of the length of the operation interval to the length of the stop interval according to the duty. The power transmission control unit sets the interval so that the length of the operation interval and the length of the stop interval are equal to each other or the length of the stop interval is longer than the operation interval when the standby mode is set.

The power transfer control unit 411 may control the duty to be 50% in the normal mode and vary the duty within the range of 0 to 50 in the standby mode. In addition, the power transmission control section allows the noise to be reduced through soft switching.

As a result, a predetermined resonance frequency wireless power signal is transmitted by the switching unit with a voltage of a predetermined magnitude outputted from the regulator, and power is supplied from the base body to the top cover assembly in a non-contact manner as an induction current is applied to the wireless power receiving unit side do.

The wireless power transmission unit is not provided with means for detecting whether or not the cover is detached by using electrical contact. However, the control unit 190 determines whether or not the cover is detached through the cover sensing unit formed of a sensor.

The wireless power receiving unit 420 includes a power receiving unit 421 and a rectifying unit 422 and is connected to the switching regulator 490.

The wireless power receiving unit 420 receives power from the base body by an induced current generated in the coil of the power receiving unit 421.

The received power is rectified and smoothed through the rectifying section 422 and input to the switching regulator 490. The switching regulator 490 outputs the operating power supplied to the load, that is, the input section or the second display. At this time, the voltage applied to the second point PV2 is 9V to 20V, and the voltage of the operating power source output from the switching regulator, that is, the voltage at the third point PV3 is 8V or 6.5V depending on the mode.

The input / output control units 246 and 470 apply a control signal to the switching regulator 490 so that the operating power is output at a voltage of a different magnitude depending on the normal mode or the standby mode.

The switching regulator 490 performs DC-DC conversion according to a control signal of the input / output control units 246 and 470, and controls the output voltage according to the normal mode or the standby mode to output an operation power having a voltage of a predetermined magnitude. For example, the switching regulator outputs operating power at a voltage of 8V in normal mode and 6.5V in standby mode.

A rectifying part 422 and a capacitor of a predetermined size are provided between the switching regulator 490 and the power receiving part 421. In the standby mode, since a wireless power signal of 6.5 V is sent from the wireless power transmission unit, it is preferable that a switching regulator is used so that the power efficiency is high. Also, in the standby mode, the switching regulator needs to output a 6.5V operating power with high efficiency, so it is preferable that a large capacity capacitor is used for the wireless power receiving part.

At this time, the switching regulator is controlled by the input / output control unit when the rectified operating power is output by the switching regulator with a predetermined magnitude of voltage, without including a separate microprocessor in the wireless power receiving unit 420. Since the wireless power receiving unit is not provided with a microprocessor, the hardware configuration is simplified and the power consumption is reduced, so that standby power for operation of the top cover assembly is reduced.

15 is a diagram showing an example of a control signal for wireless power transmission according to the present invention.

The humidifying and cleaning apparatus is configured such that the current is supplied to the power receiving unit 421 of the wireless power receiving unit 420 by the current applied to the power transmitting unit 416 so that the operating power is supplied from the base body to the top cover assembly .

In the wireless power transmission unit, a plurality of switches provided in the switching unit are turned on and off according to a switching control signal applied from the power transmission control unit 411 to the switching unit 415, and a current is applied to the power transmission unit 416.

When the operation mode is the normal mode, the power transmission control unit applies the switching control signal of the frequency designated as the switching unit to the switching unit. The PWM control signal of 120k can be applied. The power transfer control unit applies switching control signals successive from T1 to the switching unit.

On the other hand, when the operation mode is the standby mode, as shown in FIG. 15, the power transmission control section sets the interval and performs the interval switching so that the interval is switched.

In the standby mode, although the operation of the humidification cleaner is stopped, some power is supplied to maintain the standby state in order to sense the user's input and receive the transmitted data. Accordingly, the operation of the humidifying and cleaning device is stopped, but a certain amount of power consumption (standby power) is generated. If the value of the standby power is large, it is not only a waste of energy, but also a cause of an increase of the electricity charge. Therefore, it is necessary to control the standby power so as not to exceed a predetermined value. The standby power of electronic devices is regulated so as not to exceed a certain value by country.

To reduce such standby power, there is a need to reduce the output voltage of the regulator in the standby mode and also to control the power supply to the top cover assembly.

Therefore, the power transfer control unit does not apply the PWM control signal for the entire interval in the standby mode, but performs the interval switching so that the switching unit operates in each interval.

The power transmission unit forms an LC resonance circuit composed of a coil and a coffee sitter, and an ineffective circulation current due to resonance is generated. In the normal mode, the standby power is controlled to be relatively small as compared with the power consumed by the operation of the humidification cleaner, but in the standby mode, the standby power can be controlled to a relatively large value.

For example, when the regulation value for the standby power is 1 W and the power consumption by the free circulation current is 1 W, the regulation range is exceeded, and other operations can not be controlled. The free circulation current also causes a decrease in efficiency due to the power supply in a low load state.

Therefore, in order to eliminate or reduce the occurrence of the invalid circulating current, the power transmission control section performs the interval switching.

The power transmission control section is switched for the first section T1 of the first time period t1 to the second time period t2 so that the switching is stopped for the second to third time period t3 of the second section period T2 do.

The power transmission controller repeats the first section T1 (operation section) and the second section T2 (stop section) so that power is supplied to the top cover assembly in the standby mode, thereby reducing power consumption accordingly.

The power transmission control unit may set the lengths of the first section T1 and the second section T2 to be different from each other. The power transmission control unit may change the duty according to the PWM control according to the voltage output from the regulator and the voltage required in the top cover assembly. For example, when the first interval T1 and the second interval T2 are the same, the power transmission control unit can control the operation with 50% duty. In addition, when the first interval T1 and the second interval T2 are set to a length of 1: 4, the transfer control unit can control the operation with a duty of 25%.

In the stop period T2, since the circulation current is zero, the length of the operation interval and the stop interval are variably set as needed, and the power is supplied to the power source at the required voltage. The degree of reduction of the power consumption varies depending on the length of the stationary section. However, if the duty is reduced, there is a problem in amplification of the output, so it is desirable to set the duty of the fixed size moving.

FIG. 16 is a diagram showing a voltage change according to the control signal of FIG. 15. FIG.

As described above, a voltage of a certain magnitude is formed in the wireless power receiving unit, as shown in FIG. 16, by supplying power to the top cover assembly in a wireless power transmission mode through interval switching in the standby mode.

In a first section, which is an operation section, switching power is supplied to be supplied with high efficiency. In a second section, which is a stop section, the switching section of the wireless power transmission section stops operation (S11). As the capacitors are provided in the wireless power receiving unit, the coffee sitter is charged during the operation interval and the capacitors are discharged repeatedly during the stop interval.

Accordingly, the receiving-side voltage of the wireless power receiving unit is changed as shown in the second graph S12, and it is repeated according to the operation interval and the stop interval. In the standby mode, a voltage of about 6.5 V is required for operating the third communication unit as well as the operation module, the input / output control unit, and the switching regulator of the top cover assembly. However, since the voltage of the wireless power transmission unit side is 6.5 V, Accordingly, in order to output a voltage of 6.5 V from the top cover assembly on the receiving side, it is preferable that a large-capacity coffee sheater having a capacity of the coffee sheater of at least a certain size is provided.

The rectifying part of the wireless power receiving part rectifies and smoothens the operating power in which the magnitude of the voltage is changed, and inputs the rectified power to the switching regulator.

At this time, the switching regulator may be changed to another type of regulator, but it is preferable that a switching regulator is used for high efficiency transmission in the standby mode.

17 is a flowchart showing a control method according to the wireless power transmission of the humidification cleaner according to the present invention.

As shown in FIG. 17, the humidifying / cleaning device can filter out foreign matter (fine dust) contained in the air sucked in accordance with the input setting, or control and discharge the humid air, and can also humidify and discharge air .

When the top cover assembly detachable from the visual body is mounted, the controller 190 determines that the top cover assembly is in a normal state and supplies power to the controller (S615).

When the top cover assembly is detached, the controller 190 cuts off the power supply to the top cover assembly, and supplies power to the top cover assembly through the power source when the top cover assembly is in a stationary state. The control unit 190 determines whether or not the top cover assembly is stowed according to a sensing signal input from a cover sensing unit provided at a position where the top cover assembly is stowed.

If the operation mode is the normal mode, the control unit 199 controls the air clean module and the air moisturizer module of the humidification cleaner to operate according to the setting, respectively. The power supply unit applies a normal voltage to the wireless power transmission unit (S670). The power transmission control unit generates a switching control signal having a fixed duty and applies the switching control signal to the switching unit (S680). The power transmission control unit applies a continuous switching control signal having a predetermined frequency to the switching unit.

As a current is applied to the power transmission unit of the wireless power transmission unit, current flows through the wireless power reception unit due to the electromagnetic flow phenomenon, thereby supplying operating power to the top cover assembly (S690).

The input / output control units 246 and 470 determine that the received voltage is a normal voltage, and a voltage of a predetermined magnitude is supplied to each load, for example, the operation module and the illumination or the second display through the switching regulator 490, And operates in the normal operation mode (S700).

When the standby mode is selected through the operation module provided in the top cover assembly (S620), the controller sets the standby mode to the standby mode .

The control unit 190 stops all operations of the humidifying and cleaning apparatus in the standby mode and controls the power supply to the remaining parts except the part related to signal input and key input of the humidifying and cleaning apparatus such that the standby power, The supply is interrupted.

The control unit 190 includes an operation module, a second and a third communication unit for transmitting data of the operation module to the base body, a control unit for controlling transmission of data Since the operation of the input / output control unit is required, power is supplied to some parts.

The control module 190 sets a standby voltage (S630), so that the wireless power transmission unit and the wireless power reception unit of the power supply unit operate to supply power to the top cover assembly during the standby mode.

The controller 190 controls the power unit to reduce the power consumed to supply power to the top cover assembly when the standby mode is set such that the standby power is reduced. As a result, the regulator outputs a lower voltage than the normal mode in standby mode.

When the standby mode is set, the power transfer control unit 411 performs switching control by varying the duty (S640). The power transfer control unit 411 divides the duty cycle into the operation interval and the stop interval in the switching control, A control signal is generated and applied to the switching unit to perform the interval switching. At this time, the duty is changed according to the ratio of the length of the operation gap and the length of the stop section.

Accordingly, when a current is applied to the power receiving unit according to the electromagnetic induction method, power is supplied to the top cover assembly. A voltage lower than the normal voltage is applied to the wireless power receiving unit.

The input / output control units 246 and 470 control the switching regulator to convert the voltage of the operating power supplied through the wireless power receiving unit and apply operating power of standby voltage to each unit (S650). For example, in normal mode, the switching regulator outputs a voltage of 8V, and in standby mode outputs a voltage of 6.5V.

Accordingly, the top cover assembly operates in the standby mode, and a standby state is maintained until a new command is input or the standby mode is released by the operation module (S660).

Power consumed in the standby mode is reduced due to the elimination of the processor of the wireless power receiving unit and the direct control through the input / output control unit. Also, power consumption is reduced by controlling the operation of the switching unit for the wireless power transmission in the normal mode and the standby mode by the fixed switching or the interval switching.

Therefore, according to the present invention, since the wireless power transmitter and the wireless power receiver are provided, it is possible to prevent an electric accident at the terminal for electrical contact. In the present invention, the wireless power transmission unit controls the frequency of the switching unit through the variable duty control in the standby mode, so that the operating power of the set voltage can be more effectively transmitted to the top cover assembly and the power consumption can be reduced. In addition, according to the present invention, unnecessary parts can be removed and power consumption can be reduced by controlling the power received by the wireless power receiving unit through the input / output control unit.
