Description
- The present invention relates to an air cleaner, and more specifically, to an air cleaner including dehumidification and humidification functions.
- All conventional commercialized air cleaners and dehumidifiers circulate air using a method of a rotating Sikorsky or propeller, and thus noise generated when a Sikorsky blade or a propeller blade collides with air is unavoidable.
- Since some dehumidifiers do not have an air circulation function to avoid generation of noise but do not forcibly circulate humidity in the air, dehumidification efficiency is too low, and thus commercialization of most of such dehumidifiers have failed.
- Further, some heating-type humidifiers do not include an air blower but have very low humidification efficiency, and an ultrasonic humidifier that essentially requires an air blower has a serious problem of generating an air blowing noise.
- The present invention is directed to providing an air cleaner having humidification and dehumidification functions and having a low noise level due to rotating a disk without a blade.
- One aspect of the present invention provides an air cleaner which includes a housing including a suction portion through which external air is suctioned and a discharge portion through which the suctioned air is discharged, a filter disposed between the suction portion and the discharge portion and configured to purify the suctioned air, a gas pump connected with the discharge portion and configured to rotate so as to discharge the air purified by the filter to the discharge portion, and a controller configured to control a rotation direction of the gas pump, wherein the gas pump includes a rotor including a gas pump base disk disposed in and rotatably supported by the housing, a gas pump disk array in which segment disks having an open center area are disposed on the gas pump base disk to be spaced apart from each other, and a rotor magnet installed on the gas pump base disk, and a stator including a stator coil disposed in the housing and installed to face the rotor magnet.
- The air cleaner may further include a water tank configured to store water and a liquid pump connected with the same rotating shaft as the gas pump to be rotated in the same direction as the gas pump and configured to suction the water from the water tank and spray the water onto the disk array when the gas pump rotates in a forward direction and not to spray the water onto the disk array when the gas pump rotates in a reverse direction.
- The liquid pump may include a liquid pump housing including an outlet formed to face a forward rotation direction of the gas pump, a liquid pump base disk disposed in the liquid pump housing and connected with the same shaft as the gas pump to be rotatably supported by the liquid pump housing, and a liquid pump disk array in which segment disks spaced apart from each other and having an open center area are stacked on the liquid pump base disk.
- The air cleaner may further include a sensor configured to measure a temperature or humidity of external air, and the controller may be operated in a humidification mode in which air with a high moisture content is discharged by rotating the gas pump in the forward direction when the humidity of external air measured by the sensor is lower than a predetermined humidity range and may be operated in a dehumidification mode in which air with a low moisture content is discharged by rotating the gas pump in the reverse direction when the humidity of external air measured by the sensor is higher than a predetermined humidity range. Further, the controller may operate the gas pump by measuring relative humidity according to temperature.
- The air cleaner may further include a cooling element disposed between the suction portion and the discharge portion and configured to cool moisture in the air being suctioned or heat the cooled moisture according to a direction of a current flow applied from the controller.
- The air cleaner may further include a dew condensation sensor configured to measure a freezing level of dew formed in the cooling element, and the controller may be configured to freeze moisture in the air by allowing a current to flow to the cooling element in a forward direction when the freezing level measured by the dew condensation sensor is lower than a predetermined freezing level and re-melt the frozen moisture by allowing a current to flow to the cooling element in a reverse direction when the freezing level measured by the dew condensation sensor is higher than the predetermined freezing level.
- The air cleaner may further include a sterilizing part connected with the water tank or the cooling element and configured to sterilize water by electrolyzing the water in the water tank or the cooling element.
- The air cleaner may further include a water turbidity sensor configured to measure a pollution level of the water tank or the cooling element, and the controller may operate the sterilizing part when turbidity measured by the water turbidity sensor is higher than a predetermined turbidity.
- An air cleaner according to one embodiment of the present invention can purify and circulate air while noise is virtually not generated.

rotor 121 includes a gaspump base disk 121 a, a gas pump disk array with a plurality of gaspump segment disks 121 b, a spacer (not shown), and therotor magnet 121 c. The gaspump base disk 121 a is rotatably fixed to a rotating shaft and is rotated by an action with thestator coil 122 a to which the current is applied from an external power source. For example, the gaspump base disk 121 a may be rotated in a range of about 10,000 to 15,000 rotations per minute. However, the rotation number of the gaspump base disk 121 a is not limited thereto and may vary depending on a size of the gaspump base disk 121 a. - The gas pump disk array includes a plurality of gas
pump segment disks 121 b spaced apart from each other and stacked on the gaspump base disk 121 a in predetermined distances. The gaspump segment disks 121 b have an open center area, and external air is suctioned into the center area when the gaspump segment disks 121 b are rotated. - Further, for example, the gas pump disk array may be spaced apart by a spacer (not shown) disposed between the gas
pump segment disks 121 b. The gaspump segment disks 121 b are spaced apart from each other to have a space formed therebetween, and centrifugal force and a boundary layer drag effect are applied to air accommodated in each space between the gaspump segment disks 121 b when the gaspump base disk 121 a rotates, and thus the air is moved in an outer direction. - Each of the gas
pump segment disks 121 b may be fixed to an adjacent gaspump segment disk 121 b and the gaspump base disk 121 a by afixing unit 121 d such as a bolt. - The gas
pump segment disk 121 b may have a curved end portion so that gas is easily suctioned or discharged. However, the end portion of the gaspump segment disk 121 b is not limited thereto and may be formed to be angular at a right angle. - In this case, the gas
pump base disk 121 a and the gaspump segment disk 121 b may include a corrosion-resistant material or a specially coated material. - The
rotor magnet 121 c is installed in therotor 121 to interact with thestator coil 122 a and, for example, may be installed in the gaspump base disk 121 a. In this case, therotor magnet 121 c may be a permanent magnet but is not limited thereto and may be formed of an electromagnet. - The
stator 122 is disposed in thehousing 101 and includes thestator coil 122 a interacting with therotor magnet 121 c. Thestator coil 122 a may be formed on a surface facing therotor magnet 121 c, and power may be applied to thestator coil 122 a. - In this case, the
gas pump 120 may use a commercialized BLDC motor with rotating shafts formed on both sides of the commercialized BLDC motor. - The
water tank 130 is connected with thehousing 101 and includes an inner space in which water is stored. Thewater tank 130 is connected with theliquid pump 140 and may supply the water to theliquid pump 140 when theliquid pump 140 rotates. - Further, the
water tank 130 is connected with thecooling element 150 through atube 144 and the like and may store liquid generated when water frozen in thecooling element 150 is melted. - Referring to
FIGS. 5 and 6 , theliquid pump 140 is connected with the rotating shaft of thegas pump 120 to be rotated in the same direction as thegas pump 120, and may discharge or may not discharge water according to a rotation direction. - The
liquid pump 140 includes aliquid pump housing 141, a liquidpump base disk 142, and a liquidpump segment disk 143. Theliquid pump housing 141 includes anoutlet 141 a formed in the same direction as a forward rotation direction of thegas pump 120 and discharges water in a direction F1 when thegas pump 120 rotates in a forward direction and suctions air in a reverse direction F2 when thegas pump 120 rotates in a reverse direction so that the water is not discharged. For example, the outlet may be connected with thetube 144 for spraying water onto the gas pump disk array such that the water discharged from theliquid pump 140 is sprayed onto the gas pump disk array. - The liquid
pump base disk 142 is connected with the rotating shaft to rotate in the same direction of the gaspump base disk 121 a. The plurality of liquidpump segment disks 143 spaced apart from each other are stacked on the liquidpump base disk 142 to form a disk array of theliquid pump 140. The liquidpump segment disk 143 has an open center area connected with thewater tank 130 and suctions water stored in thewater tank 130 into the center area when the liquidpump segment disk 143 rotates. - Further, for example, the liquid
pump segment disks 143 may be spaced apart from each other by a distance of 1 mm by a spacer (not shown) disposed between the liquidpump segment disks 143. The liquidpump segment disks 143 are spaced apart from each other to form a space, and centrifugal force and a boundary layer drag effect are applied to air in each space between the liquidpump segment disks 143 when the liquidpump base disk 142 rotates, and thus the air is moved in an outer direction. Further, there is no blade, and thus noise generation can be minimized. - Each of liquid
pump segment disks 143 may be fixed to an adjacent liquidpump segment disk 143 and a liquidpump base disk 142 by a fixing unit such as a bolt. - The
cooling element 150 is disposed between the intake chamber and the exhaust chamber and cools and freezes moisture in the suctioned air so as to reduce humidity. Thecooling element 150 absorbs or generates heat using a Peltier effect in which heat is absorbed or generated by a current. Since thecooling element 150 can convert between heat absorption and heat generation according to a direction of a current flow, the moisture in the suctioned air may be frozen, and the frozen moisture is re-melted, and thus the water may be transferred to thewater tank 130 in a liquid state. - For example, the
cooling element 150 is formed in a funnel shape with an open center area, and thus the purified and dehumidified air may pass through the open area. - The
sensor 160 may include a humidity sensor for measuring humidity of external air, a temperature sensor measuring a temperature of external air, and a pollution level sensor for measuring a pollution level of external air. Thesensor 160 measures the humidity, temperature, and pollution level of external air and transfers the measured values to thecontroller 170. - The
controller 170 may turn thegas pump 120 on or off according to the humidity, temperature, and pollution level of external air or may change a rotation direction of thegas pump 120. - For example, the
controller 170 is operated in a humidification mode in which thegas pump 120 rotates in a forward direction when the humidity of external air measured by the humidity sensor is lower than a humidity range preset in thecontroller 170. Thegas pump 120 discharges gas regardless of rotation direction, and thus thegas pump 120 discharges the purified air. In this case, when thegas pump 120 rotates in a forward direction, theliquid pump 140 connected with the same rotating shaft as thegas pump 120 also rotates in a forward direction. When theliquid pump 140 rotates in a forward direction, the water inwater tank 130 is suctioned and discharged to an outlet of theliquid pump housing 141, and thus the water is sprayed onto the gas pump disk array through thetube 144 connected with the outlet. Therefore, thegas pump 120 discharges high humidity air including the sprayed super fine particle water drop, and thus a humidification effect is provided. - For another example, when the humidity of external air measured by the humidity sensor is higher than a humidity range preset in the
controller 170, thecontroller 170 is operated in a dehumidification mode in which thegas pump 120 rotates in a reverse direction. Since thegas pump 120 discharges gas regardless of rotation direction, thegas pump 120 discharges the purified air. In this case, when thegas pump 120 rotates in a reverse direction, theliquid pump 140 connected with the same rotating shaft as thegas pump 120 also rotates in a reverse direction. When theliquid pump 140 rotates in a reverse direction, a direction of an outlet of theliquid pump housing 141 is different from a direction of a rotation outlet of theliquid pump 140 disk array, and thus the water is not discharged. Therefore, theliquid pump 140 does not pump water and idles. - Further, in the dehumidification mode, the
cooling element 150 is operated to freeze water included in the suctioned external air so as to reduce humidity of the suctioned air. The suctioned air is re-discharged to the outside through thegas pump 120 while the humidity is lowered. - In this case, the
sensor 160 may further include a dew condensation sensor for measuring a freezing level of dew formed in thecooling element 150. When the freezing level measured by the dew condensation sensor is lower than a predetermined freezing level, thecontroller 170 freezes the moisture in the air on thecooling element 150 by allowing a current to flow to thecooling element 150 in a forward direction. Further, when the freezing level measured by the dew condensation sensor is higher than the predetermined freezing level, the controller allows a current to flow in a reverse direction and re-melts the water frozen in thecooling element 150 so as to supply the water which is frozen in thewater tank 130. - Further, the air cleaner may further include a sterilizing
part 180 for sterilizing the water in thewater tank 130 or thecooling element 150. The sterilizingpart 180 generates hydrogen and a small amount of ozone by performing electrolysis on the water, thereby sterilizing the water. - The sterilizing
part 180 may sterilize water by being operated regardless of whether thegas pump 120 and theliquid pump 140 are operated. That is, the sterilizingpart 180 may simultaneously sterilize water when thegas pump 120 and theliquid pump 140 are operated and may sterilize water while thegas pump 120 and theliquid pump 140 are not operated and air is not purified. - The sterilizing
part 180 may be, for example, a non-diaphragm titanium electrode plate. An electrode plated with platinum on a titanium plate, on which ellipses of the same size are arranged in predetermined distances, is used for a predetermined time as a positive or negative electrode without a diaphragm in a replacement manner such that water is electrolyzed, and thus a module in which hydrogen and little ozone are generated may be used. - The sterilizing
part 180 may be, for another example, a hydrogen patch. The hydrogen patch includes an insulating resin 181 formed in a lateral direction and a platinum wire 182 formed in a vertical direction and woven with the insulating resin 181. In this case, the transverse direction and the vertical direction may be switched. - The sterilizing
part 180 may be, in still another example, a hydrogen generating device. The hydrogen generating device sterilizes water using hydrogen bubbles generated when the water is electrolyzed. - The hydrogen generating device includes, for example, an electrolysis electrode part, a porous ceramic catalyst, and a resistance value sensor. The electrolysis electrode part electrolyzes and sterilizes water which is in contact with a hydrogen generating device. The porous ceramic catalyst absorbs ozone generated in an electrolysis process to reduce harmfulness. The resistance value sensor measures a resistance value of water and a concentration of electrolyte dissolved in the water and transfers the resistance value of water and the concentration of electrolyte to the
controller 170. - The
controller 170 may adjust time for changing and applying a voltage according to the received resistance value. - In this case, the
sensor 160 may further include a turbidity sensor for measuring a pollution level of thewater tank 130 or thecooling element 150. When the result value measured by the water turbidity sensor is higher than a predetermined pollution level, thecontroller 170 may operate the hydrogen-generating device until the result value is lower than the predetermined pollution level. - The
air cleaner 100 may further include adisplay part 190. Thedisplay part 190 may be, for example, a light-emitting diode (LED) for emitting red, blue, and green colors. Thedisplay part 190 may emit different colors according to a state of external air measured by the sensor. - For example, the
display part 190 may display a yellow color when humidity of external air is higher than a predetermined value, may display a red color when a pollution level of external air is higher than a predetermined value, and may display a green color when humidity and a pollution level of external air is lower than a predetermined value. - Further, the
display part 190 may display states of theair cleaner 100 or external air as well as the LED. Thedisplay part 190 may be, for example, a liquid crystal display (LCD) or an organic light-emitting diode (OLED) but is not limited thereto. - The exemplary embodiments of the present invention have been described in detail, but the scope of the present invention is not limited to the above-described specific embodiments. It should be recognized that modifications and changes made by those skilled in the art based on a basic concept of the present invention defined in the appended claims pertain to the scope of the present invention.
