On the other hand, the discharge humidification medium housing 1400 is disposed below the top cover assembly 230. The user may supply water through the operation water supply port 241 formed in the top cover assembly 230.

When the cover assembly is mounted on the visual body, the discharge humidifying medium housing 1400 may have a groove formed at one side thereof so that the top connector is easily seated. The discharge humidifying medium housing is configured such that the shape of the groove is similar to that of the top connector.

The user may supply water from the upper side of the top cover assembly 230. The water dropped into the operation water supply port 241 flows along the surface of the water supply cap 1430 and is temporarily stored in the water supply reservoir 1442, and then flows down the discharge humidification medium housing 1440 through the water supply port 1445. .

After passing through the water inlet 1445, the water falls into the interior of the visual body 210, and then falls to the top 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 surface of the visual body 210. Then, the scattered water flows along the inner surface of the visual body 210 and is stored in the water tank 300 to raise the water level of the water tank 300.

The controller determines the signal detected by the water level sensor 135 and displays the water level of the water tank 300 on the water level display unit 247.

The user can not see the water level inside the water tank 300 during the upper water supply, but can immediately check the elevated water level through the water level display unit 247 disposed around the operation water supply port 241.

Since the user can check the water level through the water level display unit 247 during the upper water supply, the upper water supply flow rate can be adjusted.

Meanwhile, in the present embodiment, the top cover assembly 230 has been described as a structure detachable from the visual body 210.

When the communication unit 181 is connected to the mobile device, the display module 160 displays the communication connection state as an icon.

The electrostatic precipitator 500 is mounted on the humidifying and cleaning device to charge and collect dust particles contained in the air.

The electrostatic precipitator 500 may be installed in the filter assembly 10 in which the plurality of filters 14 are installed. The electrostatic precipitator 500 includes a charging unit for forming an electric field, and a dust collecting unit for collecting dust particles charged by the charging unit. While the air passes through the dust collector after passing through the charging unit, dust in the air is collected in the dust collector. The charging unit includes discharge electrodes and counter electrodes disposed in parallel with the discharge electrodes, and dust is charged by corona discharge between the discharge electrodes facing each other and the counter electrodes.

The power supply unit 185 rectifies and smoothes the supplied power, changes the voltage to a voltage required for operation, and supplies the power to each unit. In addition, the power supply unit 185 supplies power to the top cover assembly separated from the body. The power supply unit 185 includes a wireless power transmitter provided in the base body and a wireless power receiver provided in the top cover assembly to supply operating power to the top cover assembly in a non-contact manner.

The controller 190 starts or ends an operation according to a command input through the input unit 245 or the communication unit 181, and sets an operation mode. The controller 190 may be implemented by one or more processors and may be implemented by a hardware device.

The controller 190 controls the electrostatic precipitator 500, the blower motor 22, the aberration motor, the ion generator 137 and / or the ultraviolet unit 136 according to the operation mode, and the lighting unit 165 and the display module. The operation state of the humidifying and cleaning device may be displayed or notified to the user through the 160 and / or the communication unit 181.

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

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

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

As shown in FIG. 11, the power supply unit 185 supplies operating power to the base body 110, and also includes a wireless power transmitter 410 and a wireless power receiver 420 to cover the top cover from the base body. Supply power to 230.

The top cover assembly 230 includes an operation module including an input unit and a display unit, and the operation module and the display unit operate by receiving power received by the wireless power receiver.

The controller 190 determines whether the top cover assembly is separated from the visual body in response to the detection signal of the cover detector 440, and controls the operation of the wireless power transmitter 410 accordingly.

When the top cover assembly is separated, the control unit 190 cannot supply power, thereby blocking the wireless power transmitter to prevent unnecessary power supply.

In addition, when the standby mode is set through the input unit, the controller 190 controls the power supply unit to operate in the standby mode, so that a voltage according to the standby mode is applied to the top cover assembly to receive a signal in the standby mode state. That is, when the power supplied to the top cover assembly is cut off in the standby mode, the input unit does not operate. Therefore, the input according to the operation setting or the release of the standby mode cannot be received, so the voltage according to the standby mode setting is applied to the top cover assembly. Control the power supply as much as possible.

In the top cover assembly, a voltage is applied to the input unit and the second display unit through the wireless power receiver, and the input / output controllers 246 and 470 controlling the input / output control the output of the second display unit in response to a signal input through the input unit. The data is transmitted to the base body through the third communication unit.

The second communication unit inputs the received data to the controller 190 and controls an operation corresponding to the data input to the controller.

In addition, in addition to the 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 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 through Bluetooth, Radio Frequency Identification (RFID), Infrared Data Association (IrDA), and the like, but are not limited thereto. 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 controllers 246 and 470 transmit data according to the standby mode setting through the third communication unit, and the controller 190 controls the air clean module according to the standby mode setting. Control the operation of the 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. Accordingly, the standby mode is set, and the voltage applied through the wireless power receiver 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 cut off for other operations. In some cases, some of the second display units may be operated. For example, the second display unit may maintain the notification display indicating the standby mode setting state, but may turn off all remaining displays.

When the standby mode release is selected through the input unit, the input / output controllers 246 and 470 transmit data corresponding to the standby mode release through the third communication unit, and the controller 190 releases the standby mode and operates the power supply to operate in the normal mode. Control the air clean module and air wash module to operate according to their settings. In addition, the controller 190 allows a general voltage to be applied from the wireless power transmitter. As the top cover assembly is applied with a general voltage, all operations are normally performed.

12 is a block diagram schematically showing a configuration of a wireless power transmitter for supplying power to the top cover assembly, and FIG. 13 is a block diagram briefly showing a wireless power receiver and a 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.

12 to 14, as the base body is provided with a wireless power transmitter, and the top cover assembly is provided with a wireless power receiver, the power supply is connected to the top cover assembly separated from the visual body by using a non-connection method. Supplied.

The controller 190 receives the cover detection signal and determines whether the top cover assembly is mounted on the visual body or separated, thereby controlling the power supply through the wireless power transmitter on and off.

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

The filter unit 413 filters an input power source, i.e., a former, to filter a current larger than or equal to a predetermined size. The filter unit 413 blocks inrush current.

The regulator 414 generates a voltage to be transmitted from the power transmission transmitter to the power transmission receiver according to a control command of the controller. The regulator transmits by changing the voltage according to the setting. For example, the regulator 414 outputs a voltage of 12V in the normal operation in response to the control command, and outputs a voltage of 6.5V in the standby mode setting. At this time, the voltages of 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 to sense the current flowing from the regulator to the switching unit. The current detector detects an overcurrent and inputs a detection signal to the power transmission controller.

The switching unit 415 applies a wireless power signal to the power transmission unit as the 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 transmitter.

In the power transmitter 416, a current is applied to the coil by the operation of the switching unit, and electricity is induced. The coil of the power transmitter is preferably provided to face the back of the side where the switching unit and the power transmission control unit are provided and the power receiver.

The power transmission control unit 411 applies a different type of switching control signal (PWM control signal) to the switching unit in the normal mode and the standby mode.

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

The power transmission controller applies a fixed frequency PWM control signal to the switching unit in the normal mode, and performs the high efficiency section switching at a lower frequency than the normal mode in the standby mode.

The power transmission controller divides the signal section into an operation section and a stop section to generate a switching control signal to operate the switching unit in the operation section. 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 the interval switching to a frequency lower than the first frequency when the standby mode is set, and different frequencies in the normal mode and the standby mode. Generates a switching control signal of.

High-efficiency section switching means that the reactive circulating current by LC resonance is large, and thus power consumption in the standby mode is increased. Thus, PWM control is performed by dividing the switching section and the stop section for each section. The power transmission control unit divides the sections so that the lengths of the operation sections and the stop sections are different so that PWM control is performed in the operation sections. For example, the PWM control can be performed only in the operation section by repeating the operation section of 2ms and the stop section of 8ms.

In addition, the power transmission controller generates the switching control signal with a duty lower than the normal mode when the standby mode is set, and adjusts the ratio of the length of the operation section to the stop section according to the duty. When the standby mode is set, the power transmission controller sets the section so that the length of the operation section and the stop section is the same, or the length of the stop section is longer than the operation section.

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

Accordingly, a predetermined resonant frequency wireless power signal is transmitted by the switching unit with a constant voltage output from the regulator, and power is supplied from the base body to the top cover assembly in a non-contact manner as the induced current is applied to the wireless power receiver side. do.

The wireless power transmitter does not include a means for detecting whether the cover is separated by using electrical contact. However, the controller 190 determines whether the cover is separated through the cover detection unit configured as a sensor.

The wireless power receiver 420 includes a power receiver 421 and a rectifier 422, and is connected to the switching regulator 490.

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

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

The input / output controllers 246 and 470 apply a control signal to the switching regulator 490 to output the operating power at voltages of different magnitudes depending on the normal mode or the standby mode.

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

The rectifier 422 and a capacitor having a predetermined size are provided between the switching regulator 490 and the power receiver 421. In the standby mode, since the 6.5V wireless power signal is transmitted from the wireless power transmitter, it is preferable that a switching regulator having high power efficiency is used. In addition, in the standby mode, the switching regulator must output 6.5V of operating power with high efficiency, and therefore, a capacitor having a large capacity is preferably used for the wireless power receiver.

At this time, the wireless power receiver 420 does not include a separate microprocessor, and when the rectified operating power is output at a voltage having a predetermined size by the switching regulator, the switching regulator is controlled by the input / output controller. Since the microprocessor is not provided in the wireless power receiver, hardware configuration is simplified and power consumption is reduced, thereby reducing standby power for the operation of the top cover assembly.

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

In the humidification and cleaning device, the wireless power transmitter 410 has a current applied to the power receiver 421 of the wireless power receiver 420 by a current applied to the power transmitter 416, so that the operating power is supplied from the base body to the top cover assembly. Supplied.

The wireless power transmitter transmits a current to the power transmitter 416 by turning on / off a plurality of switches provided in the switch according to a switching control signal applied from the power transfer controller 411 to the switch 415.

When the operation mode is the normal mode, the power transmission control unit applies the switching control signal of the frequency specified by the switching unit to the switching unit. For example, a 120k PWM control signal can be applied. The power transfer control unit applies a switching control signal continuous from T1 to the switching unit.

On the other hand, when the operation mode is the standby mode, as shown in Figure 15, the power transmission control section performs the section switching so that the switching is performed for each section by setting the section.

In the standby mode, although the operation of the humidifier cleaner is stopped, some power is supplied to maintain the standby state in order to detect a user's input and receive the transmitted data. As a result, the operation of the humidifying and cleaning device is stopped, but a certain amount of power consumption (standby power) is generated. If the standby power is a large value, not only waste of energy, but also increase the electricity bill, there is a need to control the standby power does not exceed a certain value. Standby power of electronic devices is regulated not to exceed a certain value in each country.

In order to reduce the standby power, it is necessary to reduce the output voltage of the regulator in the standby mode and to control the power supply to the top cover assembly.

Therefore, the power transmission controller does not apply a PWM control signal for all the sections in the standby mode, but performs section switching so that the switching section operates by sectioning sections.

The power transmission unit forms an LC resonant circuit composed of a coil and a coffee sheet, and generates an reactive circulating current due to resonance. In the normal mode, the power consumption according to the operation of the humidification cleaning apparatus is relatively small, but in the standby mode, the standby power must be controlled below a certain value, which may have a relatively large effect.

For example, if the regulation value for the standby power is 1W and the power consumption due to the free circulation current is 1W, it is out of the regulation range and thus other operations cannot be controlled. In addition, the free circulation current causes a decrease in efficiency due to power supply at a low load state.

Therefore, in order to eliminate or reduce the generation of the reactive circulating current, the power transmission controller performs the section switching.

The power transmission control unit is switched during the first period T1 of the first time t1 to the second time t2, and switching is stopped during the second time period to the third time t3 of the second period T2. do.

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

The power transmission controller may set the lengths of the first section T1 and the second section T2 differently. 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, the power transmission controller may control the operation to 50% duty when the first section T1 and the second section T2 are the same. In addition, the forward transmission control unit may control the operation with a duty of 25% when the first section T1 and the second section T2 are set to a length of 1: 4.

In the stop section T2, since the circulating current becomes 0, the operation section and the stop section length are variably set as necessary so that the power is supplied to the power supply with the required voltage. The degree of reduction in power consumption varies depending on the length of the stop section. However, if the duty is small, amplification may occur with respect to the output. Therefore, it is preferable to set a duty of a predetermined size.

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

As described above, as the power is supplied to the top cover assembly by the wireless power transmission method through the interval switching in the standby mode, as shown in FIG. 16, a voltage having a predetermined magnitude is formed in the wireless power receiver.

In the first section, which is an operation section, switching control is performed to supply the operation power with high efficiency. In the second section, which is a stop section, the switching unit of the wireless power transmitter stops the operation (S11). As the wireless power receiver includes a capacitor, the coffee sheet is charged during the operation period, and the capacitor is repeatedly discharged during the stop period.

Accordingly, the voltage of the receiver side of the wireless power receiver is changed as shown in the second graph S12 and is repeated according to the operation section and the stop section. In the standby mode, a voltage of about 6.5V is required to operate the operation module, the input / output control unit, the switching regulator of the top cover assembly, as well as the third communication unit, but the voltage at the wireless power transmitter is 6.5V, and the interval switching is performed. Accordingly, in order to output a voltage of 6.5V from the top cover assembly on the receiving side, it is preferable that a large capacity coffee sheet having a predetermined capacity or more is provided.

The rectifying unit of the wireless power receiver unit rectifies and smoothes the operation power of which the magnitude of the voltage is changed and inputs it to the switching regulator.

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

17 is a flowchart illustrating a control method according to wireless power transmission of the humidifying and cleaning device according to the present invention.

As shown in FIG. 17, the humidifying and cleaning device filters or discharges foreign substances (fine dust) included in the air to be sucked according to the input setting, or controls the smell, and further, humidifies and discharges the air. .

When the top cover assembly detachable from the visual body is mounted, the controller 190 determines the normal state so that power is supplied (S615).

When the top cover assembly is separated, the controller 190 cuts off power supply to the top cover assembly, and when the top cover assembly is in a normal state, the power is supplied to the top cover assembly through the power supply unit. The controller 190 determines whether the top cover assembly is mounted according to a detection signal input from the cover detection unit provided at the position where the top cover assembly is mounted.

If the operation mode is the normal mode, the control unit 199 controls the air clean module and the air moisture module of the humidifying and cleaning device to operate according to their respective settings. The power supply unit allows a normal voltage to be applied to the wireless power transmitter (S670), and the power transmission control unit generates a switching control signal having a fixed duty and applies it 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 the current is applied to the power transmitter of the wireless power transmitter, current flows to the wireless power receiver by an electromagnetic flow phenomenon, and thus operating power is supplied to the top cover assembly (S690).

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

On the other hand, the control unit is a case in which all of the set operation is completed and the operation is stopped for a predetermined time or when the standby mode is selected through the operation module provided in the top cover assembly (S620), the humidification cleaning device is in the standby mode To work.

The controller 190 stops all operations of the humidification cleaner in the standby mode, and reduces the standby power, which is the power consumed in the standby mode, so as to reduce power of the components except for the parts related to signal input and key input of the humidifier cleaner. The supply is cut off.

Even if the standby mode is set, the controller 190 releases the standby mode and receives the setting data according to the second and third communication units for transmitting data of the operation module and the operation module to the base body, and for controlling the transmission of data. Since the operation of the input / output control unit is required, power is supplied to some components.

As the operation module is provided in the top cover assembly, the controller 190 sets the standby voltage (S630), and the wireless power transmitter and the wireless power receiver of the power unit operate to supply power to the top cover assembly during the standby mode.

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

In addition, when the standby mode is set, the power transmission control unit 411 performs a switching control by varying the duty (S640), and the power transmission control unit 411 is switched so as to switch by section by dividing the operation section and the stop section during the switching control. Section switching is performed by generating a control signal and applying it to the switching unit. At this time, the duty is changed according to the ratio of the length of the operation section to the stop section.

Accordingly, when a current is applied to the power transmitter and a current is applied to the power receiver 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 receiver.

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

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

The power consumed in the standby mode is reduced by removing the processor of the wireless power receiver and performing direct control through the input / output controller. In addition, the power consumption is reduced by controlling the operation of the switching unit for the wireless power transmission in the normal mode and standby mode by fixed switching or section switching.

Therefore, according to the present invention, since the wireless power transmitter and the wireless power receiver are provided, an electric accident at the terminal for electrical contact can be prevented. According to the present invention, the wireless power transmitter controls the frequency of the switching unit through the variable duty control in the standby mode, thereby more effectively transmitting the operating power of the set voltage to the top cover assembly and reducing power consumption. In addition, according to the present invention, by controlling the power received by the wireless power receiver through the input and output control unit, it is possible to remove unnecessary components, thereby reducing power consumption.

Although the above has been illustrated and described with respect to preferred embodiments of the present invention, the present invention is not limited to the specific embodiments described above, but in the art to which the invention pertains without departing from the spirit of the invention as claimed in the claims. Various modifications can be made by those skilled in the art, and these modifications should not be individually understood from the technical spirit or the prospect of the present invention.
