1 to 7, the air purifier 100 according to an embodiment of the present invention can not only purify the polluted air from the outside without noise using a BLDC motor, and lowers the humidity according to the external humidity It has a humidification function to increase the dehumidification or humidity, the housing 101, the filter 110, the gas pump 120, the water tank 130, the liquid pump 140, the cooling element 150, the sensor unit 160 And a controller 170.

The housing 101 has a suction part 101a for sucking external air and a discharge part 101b for discharging the sucked air. The inner space of the housing 101 is partitioned into an intake chamber communicating with the inlet 101a and an exhaust chamber communicating with the outlet 101b, and communicated by an open gas pump disc array center region. The outer shape of the housing 101 may have a rectangular parallelepiped shape as shown, but is not limited thereto, and may be cylindrical. The housing 101 may be manufactured by injecting plastic or may be manufactured by pressing a metal.

The filter 110 is disposed between the suction part 101a and the discharge part 101b in the housing 101 to purify the air by removing foreign substances from the air sucked from the suction part 101a.

The filter 110 is, for example, a primary filter 110 to filter dust of a certain size to remove large particles, and a secondary filter 110 to remove dust of small particles by collecting dust with negative ions by plasma discharge. It may be configured to include.

The gas pump 120 is disposed in the housing 101 to suck the purified air from the filter 110 to discharge the purified air to the discharge portion 101b of the housing 101, and the rotor with the rotor magnet 121c installed therein. And a stator 122 including a stator coil 122a to which a current is applied by interaction so that the 121 and the rotor 121 are rotated.

The rotor 121 includes a gas pump base disk 121a, a gas pump disk array 121b, a spacer (not shown), and a rotor magnet 121c. The gas pump base disk 121a is fixed to the rotation shaft so as to be rotatable, and is rotated by the action of the stator coil 122a to which a current is applied from an external power source. For example, the gas pump base disk 121a may be rotated by about 10,000 to about 15,000 revolutions per minute. However, the rotation speed of the gas pump base disk 121a is not limited thereto, and may vary according to the size of the gas pump base disk 121a.

In the gas pump disk array, a plurality of gas pump segment disks 121b spaced apart from each other are stacked on the gas pump base disk 121a at regular intervals. The gas pump segment disk 121b has an open central region, and external air is sucked into the central region as the gas pump segment disk 121b is rotated.

In addition, the gas pump disk array may be, for example, spaced apart by a spacer (not shown) disposed between each gas pump segment disk 121b. Since each gas pump segment disk 121b is spaced apart from each other to form a space, the centrifugal force and boundary layer traction effect on the air located between each gas pump segment disk 121b while the gas pump base disk 121a is rotated. Drag Effect is applied to carry air outward.

Each gas pump segment disk 121b may be fixed to the adjacent gas pump segment disk 121b and the gas pump base disk 121a by fixing means 121d such as a bolt.

Gas pump segment disk 121b may be formed in a curved end portion to facilitate the intake and discharge of gas. However, the end of the gas pump segment disk 121b is not limited thereto, and may be formed to be cornered at right angles.

Here, the gas pump base disk 121a and the gas pump segment disk 121b may include a material having corrosion resistance or a material having a special coating.

The rotor magnet 121c is installed in the rotor 121 and interacts with the stator coil 122a. For example, the rotor magnet 121c may be installed in the gas pump base disk 121a. The rotor magnet 121c may be a permanent magnet, but is not limited thereto and may be configured as an electromagnet.

The stator 122 is disposed in the housing 101 and includes a stator coil 122a that interacts with the rotor magnet 121c. The stator coil 122a may be formed on a surface opposite to the rotor magnet 121c and power is applied.

In this case, the gas pump 120 may be one having a rotating shaft on both sides of a commercially available brushless DC (BLDC) motor.

The water tank 130 is connected to the housing 101 and has an internal space for storing water. The water tank 130 may communicate with the liquid pump 140 to supply water to the liquid pump 140 when the liquid pump 140 is rotated.

In addition, the water tank 130 is connected via the cooling element 150 and the tube tube 144, when the water frozen in the cooling element 150 is thawed, it can store the liquid.

5 to 6, the liquid pump 140 is connected to the same rotation shaft as the gas pump 120 and rotates in the same direction as the gas pump 120, and may or may not discharge water according to the rotation direction. .

The liquid pump 140 includes a liquid pump housing 141, a liquid pump base disk 142, and a liquid pump segment disk 143. The liquid pump housing 141 forms an outlet 141a having the same direction as the forward rotation direction of the gas pump 120 so that water is discharged (F1) when the gas pump 120 is rotated forward, and the gas pump 120 Is reversely rotated so that air is sucked in the opposite direction (F2) so that water is not discharged. Here, the outlet may be connected to the tube tube 144 sprayed on the gas pump disk array, for example, so that water discharged from the liquid pump 140 may be sprayed on the gas pump disk array.

The liquid pump base disk 142 is connected to the rotating shaft and rotates in the same direction as the gas pump base disk 121a. The plurality of liquid pump segment disks 143 are spaced apart from each other on the liquid pump base disk 142 to form a liquid pump 140 disk array. The liquid pump segment disk 143 has an open central region connected to the water tank 130, so that the water stored in the water tank 130 is sucked into the central region as the liquid pump segment disk 143 is rotated.

In addition, the liquid pump segment disk 143 may be spaced at an interval of 1 mm by, for example, a spacer (not shown) disposed between each liquid pump segment disk 143. Since each liquid pump segment disk 143 is spaced apart from each other to form a space, the centrifugal force and boundary layer traction effect on the air located between each liquid pump segment disk 143 as the liquid pump base disk 142 is rotated. Drag Effect is applied to carry air outward, but there is no wing to minimize noise.

Each liquid pump segment disk 143 may be fixed to the adjacent liquid pump segment disk 143 and the liquid pump base disk 142 by fixing means such as bolts.

The cooling element 150 may be disposed between the intake chamber and the exhaust chamber, thereby lowering humidity by cooling and freezing moisture in the sucked air. The cooling device 150 generates endothermic or exothermic heat by using a Peltier effect in which heat is absorbed or generated by current. Since the cooling element 150 can switch between endothermic and exothermic according to the current direction, the cooling element 150 may not only freeze moisture in the sucked air, but also thaw the frozen water again to provide water to the water tank 130 in a liquid state. Can be transported

For example, the cooling device 150 may be formed in a shape of a funnel having an open central area, and may be formed to allow purified and dehumidified air to enter the opened area.

The sensor unit 160 may include a humidity sensor for measuring the humidity of the outside air, a temperature sensor for measuring the temperature of the outside air, and a pollution degree sensor for measuring the pollution degree of the outside air. The sensor unit 160 measures humidity, temperature, and pollution degree of the outside air and transfers the result value to the controller 170.

The controller 170 may operate the gas pump 120 on / off or vary the rotation direction of the gas pump 120 according to the humidity, temperature, and pollution degree of the external air.

For example, the controller 170 operates in a humidifying mode in which the gas pump 120 is rotated forward when the humidity of the outside air measured by the humidity sensor is lower than the humidity range set in the controller 170. Since the gas pump 120 discharges gas regardless of the rotation direction, the gas pump 120 discharges purified air. Here, as the gas pump 120 is rotated in the forward direction, the liquid pump 140 connected to the same rotation shaft is also rotated in the forward direction. When the liquid pump 140 rotates in the forward direction, the water filled in the water tank 130 is sucked out and discharged to the outlet of the liquid pump housing 141, so that the liquid pump 140 is connected to the gas pump disk array through a tube tube 144 connected to the outlet. Will spray water. As a result, since the gas pump 120 discharges the high humidity air including the injected ultra-molecular droplets, the gas pump 120 has a humidifying effect.

As another example, the controller 170 operates in a dehumidification mode in which the gas pump 120 is rotated reversely when the humidity of the outside air measured by the humidity sensor is higher than the humidity range set in the controller 170. Since the gas pump 120 discharges gas regardless of the rotation direction, the gas pump 120 discharges purified air. Here, as the gas pump 120 rotates in the reverse direction, the liquid pump 140 connected to the same rotation shaft is also rotated in the reverse direction. When the liquid pump 140 is rotated in the reverse direction, the outlet direction of the liquid pump housing 141 is different from that of the rotation direction of the disk array of the liquid pump 140 to prevent water from being discharged. As a result, the liquid pump 140 idles without pumping water.

In addition, in the dehumidification mode, the cooling element 150 is operated to freeze moisture contained in the sucked outside air, thereby lowering the humidity of the sucked air. Inhaled air is discharged back to the outside through the gas pump 120 in a low humidity.

At this time, the sensor unit 160 may further include a condensation sensor for measuring the degree of freezing formed on the cooling element 150. In this case, the control unit 170 receives the freezing degree measured from the condensation sensor and lowers the preset freezing degree so that current flows in the forward direction to the cooling element 150 to freeze moisture in the air to the cooling element 150. In addition, if the degree of freezing measured by the condensation sensor is higher than the preset degree of freezing, current flows in the cooling element 150 in a reverse direction to re-dissolve moisture frozen in the cooling element 150 to supply water frozen in the water tank 130. Can be.

The air purifier may further include a sterilization unit 180 for sterilizing water present in the water tank 130 or the cooling device 150. The sterilization unit 180 generates hydrogen by electrolyzing water and sterilizes water by generating a small amount of ozone.

The sterilization unit 180 may operate regardless of whether the gas pump 120 and the liquid pump 140 are driven to sterilize water. That is, the sterilization unit 180 may sterilize water at the same time when the gas pump 120 and the liquid pump 140 are being driven, and the gas pump 120 and the liquid pump 140 are stopped to purify the air. Water can be sterilized even if it is not.

The sterilization unit 180 may be, for example, a barrier-free titanium electrode plate. Electroplated water can be used by replacing the electrode plated with platinum on the titanium plate with the same size ellipse arranged at regular intervals with a positive electrode for a certain time without a diaphragm to generate hydrogen and a small amount of ozone. .

The sterilization unit 180 may be a hydrogen patch as another example. The hydrogen patch is formed to include the insulating resin 181 formed in the horizontal direction and the platinum wire 182 formed in the vertical direction and woven with the insulating resin 181. Here, the horizontal direction and the vertical direction may be reversed.

The sterilization unit 180 may be, for example, a hydrogen generator. The hydrogen generator sterilizes water through hydrogen bubbles generated by electrolysis of water.

The hydrogen generator includes, for example, an electrolysis electrode unit, a porous ceramic catalyst, and a resistance sensor unit 160. The electrolysis electrode unit electrolyzes and sterilizes the water contacting the hydrogen generator. Porous ceramic catalysts absorb ozone from the electrolysis process and reduce the hazard. The resistance sensor 160 measures the resistance of the water, measures the concentration of the electrolyte dissolved in the water, and transmits the measured value to the controller 170.

The controller 170 may adjust the time for applying the variable voltage according to the received resistance value.

At this time, the sensor unit 160 may further include a water turbidity sensor for measuring the degree of contamination of the water tank 130 or the cooling element 150. The controller 170 may receive a result value measured by the water turbidity sensor and operate the hydrogen generator until it is lower than the preset turbidity if the turbidity is higher than the preset turbidity.

The air cleaner 100 may further include a display unit 190. For example, the display unit 190 may be an LED light emitting device that emits red, blue, or green light. The display unit 190 may emit different colors according to the state of the outside air measured by the sensor.

For example, the display unit 190 displays yellow when the humidity of the outside air is higher than the preset value, and displays red when the pollution of the outside air is higher than the preset value, and green when the humidity and the pollution of the outside air are lower than the preset value. Can be displayed as

In addition, the display unit 190 may indicate the state of the air cleaner 100 or the state of external air as well as the LED light emitting device. The display unit 190 may be, for example, an LCD or an OLED, but is not limited thereto.
